Description

Description

[0001] The present invention relates to a transport device for transporting goods, in particular plate-shaped goods, according to the preamble of claim 1 and to arrangements comprising such a transport device.

[0002] Transport devices for transporting goods, in particular plate-shaped goods, are known from the prior art, which comprise a base frame and at least one support device arranged on or at the base frame (see e.g. CN 106829478 B). The goods to be transported can be arranged or are arranged on the base frame and the at least one support device serves to support the goods to be transported, in particular laterally, which can be plate goods such as windows, doors, railings, window grilles, fence panels, sheet metal panels, etc. In the transport device shown in CN 106829478 B, the plate goods to be transported are stored indirectly on the base frame, in that the support devices comprise L-shaped angles which are arranged on the base frame and on which the plate goods are arranged.

[0003] Transport devices are also known which comprise wheels arranged on the base frame for moving the transport device (see e.g. EP 0 603 151 A2). In the transport device shown in EP 0 603 151 A2, the goods to be transported can be arranged directly on the base frame and can be supported laterally by a U-shaped support device arranged on the base frame. Wheels in the form of rigid fixed castors are arranged at the four corners of the essentially rectangular base frame. This allows the transport device to be moved on a surface.

[0004] Furthermore, transport devices are known which can be placed on a surface and which have wheels which can be moved back and forth between a storage position and a driving position by means of a movement device (see, for example, EP 3 431 363 A1). In the driving position, the load of the transport device rests on the wheels and in the storage position the wheels are unloaded. However, EP 3 431 363 A1 does not provide any further details about the movement device.

[0005] The object of the invention is to provide a transport device which is improved compared to the prior art and which in particular comprises an improved movement device by which the movement of the at least one wheel from the storage position to the driving position is facilitated.

[0006] This object is achieved by a transport device having the features of claim 1. Advantageous embodiments of the invention are defined in the dependent claims.

[0007] The invention provides that the movement device comprises at least one pivot rod rotatably mounted on the base frame and a lever attached to the at least one pivot rod, wherein the at least one wheel is arranged on the at least one pivot rod, preferably by means of a holder, wherein an axis of rotation of the at least one wheel is eccentric to a central axis of the at least one pivot rod, wherein by means of lever actuation of the lever and the associated rotation of the at least one pivot rod, the at least one wheel can be moved from the storage position to the driving position and vice versa.

[0008] The lever is rigidly or non-rotatably connected to the at least one pivot rod, whereby a movement of the lever causes a rotation of the at least one pivot rod rotatably mounted on the base frame. The at least one wheel can be arranged on the at least one pivot rod by means of a holder known per se, wherein the holder can also be rigidly or non-rotatably connected to the at least one pivot rod. The holder can be, for example, a fork-shaped holder, wherein an axis of rotation of the wheel runs between the forks. The at least one wheel can be, for example, a transport roller, transport roller, fixed roller or heavy-duty fixed roller.

act.

[0009] By arranging the at least one wheel on the at least one swivel rod, in which the rotation axis of the at least one wheel runs eccentrically to the central axis of the at least one swivel rod, the at least one wheel pivots about the central axis when the lever is operated. Starting from the storage position, the at least one swivel rod with at least one wheel arranged on it is thus rotated when the lever is operated, whereby the at least one wheel is pivoted about the central axis until it rests on a surface. By further pivoting in the same direction, the transport device is lifted from the surface and rests at least partially on the at least one wheel, which is then in the driving position. When moving from the storage position to the driving position, the transport device is lifted, whereby the weight of the transport device acts at least partially on the at least one wheel. In the driving position, the transport device can be moved on the surface, whereby the transport device represents a mobile transport device.

[0010] In a corresponding manner, starting from the driving position of the at least one wheel, when the lever is operated in the other direction, the at least one wheel is pivoted upwards in relation to the central axis until it is relieved of load, whereby the transport device is lowered onto the ground. When moving from the driving position to the storage position, the transport device is lowered towards the ground or floor. In the storage position, the at least one wheel has no contact with the ground, it is essentially completely relieved of load and has no load-bearing function. The transport device can thus be placed stationary on the ground and rest on the ground on storage surfaces and/or feet that can be arranged on the base frame.

[0011] According to a preferred embodiment, it can be provided that the movement device comprises at least one pulling device, wherein the at least one pulling device is arranged on the lever in an articulated manner, preferably pivotable relative to the lever. The pulling device, which is arranged on the lever in an articulated manner, allows the lever to be actuated by means of the pulling device. When the pulling device is pulled, the lever is moved accordingly, whereby the at least one pivoting rod is rotated and the at least one wheel arranged on the at least one pivoting rod is moved from the storage position to the driving position. Alternatively or in addition to the pulling device, the movement device can comprise at least one further actuating device in order to actuate the lever hydraulically, pneumatically and/or by means of a spindle drive.

[0012] Preferably, it can be provided that a connecting end of the at least one pulling device is pivotally connected to the lever, preferably to a lever end of the lever, wherein preferably an actuating end of the at least one pulling device has a handle. The provision of a handle at the actuating end of the pulling device makes it easier to actuate the lever.

[0013] In a preferred embodiment, it can be provided that the transport device comprises a support device, preferably arranged on the lever and/or on the support device, for supporting the at least one pulling device. The support device, which can protrude from the lever and can be formed in one piece with the lever or can be arranged, for example, on a mast of the support device, serves to support the pulling device. In particular, if the pulling device is designed as a rod, the pulling device can rest on the support device (when not in use) and thus assume a defined position relative to the lever.

[0014] According to a particularly preferred embodiment, it can be provided that the at least one traction device comprises a traction rod and a traction cable connected to the traction rod. The traction rod is pivotably arranged on the lever (preferably at the lever end of the lever) with one end, which represents the connecting end of the traction device. The traction cable is attached to the traction rod at an end of the traction rod facing away from the connecting end, and the traction cable is connected to the traction device at its free end, which represents the actuating end of the traction device.

direction, can have a handle.

[0015] In a particularly preferred embodiment, it can be provided that the at least one traction device comprises a locking device for locking the at least one traction device to the transport device. The locking device serves in particular to lock the lever position when the at least one wheel is in the driving position. In other words, starting from the storage position of the at least one wheel, the traction device can be actuated until the at least one wheel has been pivoted into a driving position in which the load of the transport device rests at least partially on the at least one wheel. This position of the traction device and thus the position of the lever can then be locked by means of the locking device, so that the at least one wheel remains in the driving position, even if no further actuation or force is exerted on the traction device.

[0016] It can preferably be provided that when the towing device is locked, the central axis of the at least one swivel rod and the axis of rotation of the at least one wheel span a plane that runs obliquely to the vertical, the vertical and the plane that runs obliquely to the vertical enclosing a dead center angle. As a result, the towing device is locked before the dead center of the movement of the axis of rotation of the at least one wheel relative to the central axis of the at least one swivel rod is reached. In other words, the central axis of the at least one swivel rod and the axis of rotation of the at least one wheel span a plane that runs obliquely to the vertical (the central axis and the axis of rotation are therefore not vertically above one another). When the at least one wheel is pivoted from the storage position to the driving position, the at least one wheel is not pivoted beyond the dead center at which the central axis of the swivel rod and the axis of rotation of the at least one wheel would intersect a common vertical. If the dead center is not exceeded, a movement from the driving position to the storage position can be initiated when the lock is released, favored by the weight of the transport device.

[0017] Preferably, it can be provided that the transport device comprises a limit stop, wherein the limit stop limits a movement of the at least one pulling device in the pulling direction, wherein preferably when the position of the at least one pulling device is limited by the limit stop, the dead center angle is greater than 0°. In other words, the limit stop prevents the dead center from being exceeded.

[0018] It can be provided that the locking device is arranged at an end of the pull rod facing the pull rope or between the pull rod and the pull rope. The locking device can also be arranged on the pull rod or on the pull rope.

[0019] It can be provided that the locking device comprises two clamping plates, wherein the traction cable is arranged between the two clamping plates.

[0020] According to a preferred embodiment, the locking device can comprise a projection - preferably in the form of a locking lug - which can be brought into engagement with a corresponding counter-projection arranged on the transport device - preferably in the form of a locking hook - for locking and can be disengaged to release the locking. When the projection is engaged with the counter-projection, the pulling device and thus the lever position is locked. In the locked state, no lever actuation is possible. When the projection is brought out of engagement with the counter-projection again, the lever can be actuated in both directions by means of the pulling device. Preferably, as described above, a limit stop is provided in order to limit a pulling movement of the pulling device in the pulling direction, so that the dead center of the movement of the axis of rotation of the at least one wheel relative to the central axis of the at least one pivot rod is not exceeded.

[0021] Preferably, it can be provided that the counter projection is arranged on the at least one support device. The counter projection can be formed, for example, from a folded sheet metal which is arranged on the at least one support device and

through which the traction device is guided, for example by providing an opening (e.g. elongated hole) in a limit stop of the folded sheet through which the traction cable of the traction device is guided.

[0022] The traction cable can then be pulled (and the lever can thus be operated) until the projection of the locking device is in a position in which it can be brought into engagement with the counter projection. In this position, which corresponds for example to a lever position in which at least one wheel is in the driving position, the projection can then be brought into engagement with the counter projection and the lever position can thus be locked. The folded sheet metal can also simultaneously form or include a limit stop which prevents the dead point from being exceeded when the traction device is pulled further in the pulling direction.

[0023] According to a particularly preferred embodiment, it can be provided that the movement device for dampening the movement of the at least one wheel from the driving position into the storage position comprises at least one damping device, preferably in the form of an oil brake.

[0024] When pivoting the at least one wheel from the storage position to the driving position, the at least one wheel is preferably not pivoted beyond the dead center at which the center axis of the pivot rod and the axis of rotation of the at least one wheel would intersect a common vertical. In other words, even in the driving position, the vertical distance between the center axis and the axis of rotation is smaller than the distance between the center axis and the axis of rotation along a common straight line. As a result, in the driving position of the at least one wheel, a lever effect arises between the point of contact of the at least one wheel with the ground and the at least one pivot rod, and the weight of the transport device supports pivoting of the at least one wheel back into the storage position. If the transport device is heavily loaded and therefore heavy, and the locking of the traction device is released, without the provision of a damping device, an abrupt change of position of the at least one wheel from the driving position to the storage position would occur and the transport device could possibly be set down abruptly and unintentionally on the ground. In order to counteract this unwanted movement, a damping device can be provided, which is preferably designed as an oil brake. The damping device preferably only has a damping effect on the movement during a movement of the at least one wheel from the driving position to the storage position, i.e. during a lowering movement of the transport device. As a result, the damping device offers no resistance during the lifting movement of the transport device, whereas it has a damping effect during the lowering movement of the transport device and thus brakes this movement so that the transport device can gently touch down on the ground.

[0025] Preferably, it can be provided that the at least one damping device is arranged between the lever and the base frame. The damping device is connected on the one hand (at a first end) to the lever and on the other hand (at a second end) to the base frame. Since the at least one pivot rod is rotated during the transition from the driving position to the storage position and the lever is attached to the at least one pivot rod and is thereby moved, the lowering movement of the transport device can be dampened by arranging the damping device between the lever and the base frame. Preferably, it can be provided that the fastening point of the damping device on the lever and/or base frame has an elongated hole, so that the first phase of the lowering movement (i.e. while the fastening is being moved along the elongated hole) still takes place without braking, which makes it easier to release any locking mechanism on the pulling device.

[0026] In a particularly preferred embodiment, it can be provided that at least two wheels are arranged on the at least one pivot rod, spaced apart from one another along the at least one pivot rod. For example, two wheels can be provided, which are arranged at the respective ends of the at least one pivot rod.

and whose axes of rotation are eccentric to the central axis of the at least one pivot rod.

[0027] Preferably, it can be provided that the base frame has a longitudinal extension, wherein the at least one pivot rod is arranged substantially transversely to the longitudinal extension on the base frame. In other words, the base frame has a longitudinal extension and a transverse extension, wherein the at least one pivot rod runs substantially parallel to the transverse extension. The at least one pivot rod can, for example, run along approximately 50% to approximately 100% of the transverse extension.

[0028] It can be provided that the at least one swivel rod is arranged substantially centrally in relation to the longitudinal extension on the base frame. An approximately central arrangement of the at least one swivel rod in relation to the longitudinal extension makes handling of the transport device easier. If, for example, two wheels are arranged on the swivel rod, a vertical axis is formed between the two wheels, around which the transport device can be easily rotated, which makes steering the transport device easier when driving on the ground or floor.

[0029] According to a preferred embodiment, it can be provided that the at least one pivoting rod is arranged off-center in relation to the longitudinal extent on the base frame. Preferably, the at least one pivoting rod is arranged off-center in a direction opposite to a pulling direction of the pulling device. As a result, when the pulling device is actuated and the transport device is raised in this way, the transport device tilts (around the point of contact of the at least one wheel with the ground) and the transport device tips to the ground at the end that is further away from the at least one pivoting rod. If the pulling device is arranged accordingly, the transport device then tips to the ground at the end at which the pulling device was also actuated.

[0030] It can be provided that the at least one pivot rod is arranged eccentrically with respect to the longitudinal extent on the base frame by approximately 0.5% to approximately 20%, preferably approximately 0.5% to approximately 5% or approximately 10% to approximately 20% of the longitudinal extent. If the transport device only comprises a pivot rod with a lever arranged thereon, the pivot rod can preferably be arranged eccentrically with respect to the longitudinal extent on the base frame by approximately 0.5% to approximately 5%. If the transport device comprises a pivot rod with a lever arranged thereon and additionally a support wheel that can be pivoted relative to the base frame (as will be described below), the pivot rod can preferably be arranged eccentrically with respect to the longitudinal extent on the base frame by approximately 10% to approximately 20%.

[0031] According to a further embodiment variant, it can be provided that at least two pivoting rods spaced apart from one another in the direction of the longitudinal extension are arranged on the base frame.

[0032] It can be provided that the movement device comprises a first pivot rod with a first lever arranged thereon and a second pivot rod with a second lever arranged thereon, which is spaced apart from the first pivot rod in the direction of the longitudinal extension, wherein a first pulling device is preferably arranged in an articulated manner on the first lever and a second pulling device is arranged in an articulated manner on the second lever. In this way, the first pulling device can be actuated from a first end of the transport device, which actuates the first lever and thus rotates the first pivot rod and can thus move the wheels arranged on the first pivot rod back and forth between the storage position and the driving position. The second pulling device can be actuated from a second end of the transport device opposite the first end, which actuates the second lever and thus rotates the second pivot rod and can thus move the wheels arranged on the second pivot rod back and forth between the storage position and the driving position. The pulling devices can be constructed as described above and equipped with locking devices. In particular, the pulling devices can each comprise a pull rod and a pull rope with a handle. When pulling on the first pull rope

From the first end of the transport device, the wheels arranged on the first swivel rod swivel from their storage position to their driving position, thereby lifting the transport device in the area of the first swivel rod. The driving position of the wheels on the first swivel rod can be locked using a locking device. In a similar way, when the second pull rope is pulled from the second end of the transport device, the wheels arranged on the second swivel rod swivel from their storage position to their driving position, thereby lifting the transport device in the area of the second swivel rod. The driving position of the wheels on the second swivel rod can be locked using a locking device. Overall, this means that the load can be distributed between both swivel rods, making it easier to lift the transport device.

[0033] In a particularly preferred embodiment, it can be provided that at least one support wheel is arranged on the base frame, wherein the at least one support wheel is preferably designed as a steering roller. The at least one support wheel can also be designed as a rigid roller, e.g. in the form of a fixed roller.

[0034] Preferably, it can be provided that the at least one support wheel is relieved of load when the at least one wheel is in the storage position, wherein the at least one support wheel is preferably relieved of load when the at least one wheel is in the driving position and the base frame is horizontally aligned. In other words, the transport device does not rest on the at least one support wheel when the at least one wheel is in the driving position and the base frame is horizontally aligned. In this position, the transport device can tilt about the point of contact of the at least one wheel with the ground or floor, so that the at least one support wheel arranged on the base frame is brought into contact with the ground or floor. In the tilted state, the transport device rests on the at least one wheel and the at least one support wheel.

[0035] In a further preferred embodiment, it can be provided that the at least one support wheel is arranged on a swivel bracket, wherein the swivel bracket is arranged on the base frame so that it can pivot relative to the base frame, wherein the swivel bracket is connected to the lever with a connecting lever. The connecting lever can be connected to the lever in an articulated manner on the one hand and to the swivel bracket on the other. When the lever is actuated to move the at least one wheel from the storage position to the driving position, the connecting lever is also actuated and swivels the swivel bracket so that the support wheel arranged on the swivel bracket is also swiveled towards the ground. When the at least one wheel is in the driving position, the load of the transport device is then supported on the at least one wheel on the one hand and on the at least one support wheel on the other. When the lever is actuated in the opposite direction, i.e. to move the at least one wheel from the driving position to the storage position, the swivel bracket moves accordingly and the at least one support wheel is relieved of load and no longer has a supporting function.

[0036] According to a preferred embodiment, it can be provided that the at least one support wheel is arranged at one end of the base frame with respect to a longitudinal extension of the base frame, wherein preferably the at least one support wheel is arranged substantially centrally on the base frame with respect to a transverse extension of the base frame running transversely to the longitudinal extension.

[0037] Preferably, it can be provided that a support wheel is arranged at each end of the base frame in relation to the longitudinal extension. The provision of support wheels at both ends of the base frame facilitates the handling of the transport device. To facilitate maneuvering of the transport device, it can be provided that one of the support wheels is designed as a swivel castor and the other as a rigid castor.

[0038] According to a particularly preferred embodiment, it can be provided that at least one parking device, preferably in the form of a foot or a runner, is arranged on the base frame, wherein the transport device rests on a base when the at least one wheel is stored by means of the at least one parking device. With other

According to the invention, the at least one parking device has at least one parking surface which is in contact with the ground or floor when the at least one wheel is in the storage position in which it has no contact with the ground and therefore no supporting function.

[0039] Preferably, it can be provided that when the at least one wheel is stored, at least one insertion space between the base frame and the ground remains free, wherein a tine or a fork of a forklift or a pallet truck can be inserted into the at least one insertion space. This enables or facilitates the transport of the transport device by means of a forklift or pallet truck.

[0040] In a preferred embodiment, it can be provided that the base frame comprises at least one storage device, wherein the goods to be transported can be placed or are placed on the at least one storage device. In this case, the goods are stored directly on the base frame by being stored on the at least one storage device. The at least one storage device can comprise at least one support surface and/or at least one strut. The at least one storage device can be constructed like a frame, wherein at least one support surface and/or at least one strut is or are arranged within the frame, wherein the goods can be placed on the frame and/or the at least one support surface and/or the at least one strut. The base frame can also itself represent one or more storage devices in the form of struts arranged on the base frame or forming the base frame. The base frame can thus comprise a frame with a longitudinal extension and a transverse extension, wherein at least one support surface and/or at least one strut is or are arranged within the frame.

[0041] Preferably, it can be provided that the base frame is aligned substantially horizontally. However, it can also be provided that the base frame and/or the at least one storage device is or are slightly inclined relative to the horizontal (for example by about 1° to 30°, preferably about 3°). In other words, the at least one storage device can be inclined obliquely relative to the horizontal starting from an outer end of the storage device along a transverse extension of the base frame. This reduces the risk of the goods placed on the storage device falling sideways from the storage device.

[0042] For the transport of, for example, rod-shaped goods, the transport device or its support device(s) or storage device(s) can also be equipped with compartments for rod material.

[0043] Preferably, it can be provided that the at least one support device extends substantially vertically upwards from the base frame.

[0044] According to a preferred embodiment, it can be provided that the at least one support device comprises a support frame, wherein the support frame comprises at least one support leg running obliquely to the vertical, preferably several support legs arranged in pairs in a substantially A-shape. Plate-shaped goods in particular can be leaned against the support legs. The inclination of the support legs can, for example, be between approximately 1° and 30° deviating from the vertical. Two opposing support legs running obliquely to the vertical can be arranged in an A-shape when viewed from the side.

[0045] In a further embodiment, it can be provided that the support frame comprises at least one support leg, preferably substantially at a right angle, protruding from the at least one support leg, wherein the at least one support leg is preferably arranged on the base frame. The goods are stored indirectly on the base frame by being stored on the support legs and being supported laterally by the support legs.

[0046] According to a particularly preferred embodiment, it can be provided that the at least one support device comprises a lifting beam for lifting the transport device by means of a lifting device, wherein preferably at least one crane eye and/or at least one lashing eye is or are arranged on the lifting beam. The lifting beam can be a part

of the support frame (e.g. the upper beam).

[0047] All elements of the frames or rods of the transport device (e.g. base frame, parking device, storage device, support device, support frame, lifting beam) can be designed as hollow profiles, in particular rectangular hollow profiles, as U-profiles or as L-profiles.

[0048] Protection is also sought for an arrangement comprising a transport device according to the invention and at least one external lifting device, characterized in that the at least one external lifting device comprises a handle bar, a crossbar arranged on the handle bar, preferably running transversely to the longitudinal extent of the handle bar, and at least one lifting bolt for lifting the transport device, wherein the at least one lifting bolt is formed by the crossbar or is arranged on the crossbar, wherein at least one support wheel, preferably at least two support wheels, is or are arranged on the crossbar, wherein the at least one lifting bolt for lifting the transport device can be brought into engagement with the base frame, preferably with at least one suspension lug formed or arranged on the base frame, particularly preferably corresponding to the at least one lifting bolt.

[0049] The at least one suspension lug can be formed, for example, by two or more spaced-apart metal sheets which are arranged on the base frame and each have a recess which corresponds to the shape of the at least one lifting bolt.

[0050] According to a preferred embodiment, it can be provided that an axis of rotation of the at least one support wheel is concentric to a central axis of the crossbar, wherein preferably the at least one lifting bolt is arranged on a bolt holder protruding from the crossbar, wherein preferably a first imaginary line along the handlebar to the central axis and a second imaginary line from the at least one lifting bolt to the central axis span a common plane and enclose an angle of approximately 90° to approximately 150°, particularly preferably approximately 100° to approximately 120°.

[0051] To lift the transport device, the lifting device can be pushed under the transport device and the lifting bolt can be brought into engagement with a lug on the base frame by pivoting the lifting device (by moving the handle bar towards the ground so that the lifting device pivots around the support wheels resting on the ground, whereby the bolt holder protruding from the crossbar, together with the lifting bolt arranged on it, pivots towards the transport device). If the lifting device is pivoted further, the transport device is raised so that it now also rests on the support wheels and can be moved along by rolling on them.

[0052] According to a further preferred embodiment, it can be provided that the at least one support wheel is arranged on the crossbar by means of a wheel holder, wherein an axis of rotation of the at least one support wheel is eccentric to a central axis of the crossbar, wherein preferably the at least one lifting bolt is formed by the crossbar, wherein preferably a first imaginary line along the handlebar to the central axis and a third imaginary line from the axis of rotation of the at least one support wheel to the central axis span a common plane and enclose an angle of approximately 110° to approximately 170°, particularly preferably approximately 145° to approximately 165°.

[0053] The at least one support wheel is arranged on the crossbar by means of a wheel holder known per se, whereby the wheel holder can be rigidly or rotationally fixedly connected to the crossbar. The wheel holder can be, for example, a fork-shaped wheel holder, whereby an axis of rotation of the support wheel runs between the forks. The at least one support wheel can be, for example, a transport roller, transport roller, fixed roller or heavy-duty fixed roller.

[0054] To push the transport device, the lifting device can be pushed under the transport device and the lifting bolt can be moved by pivoting the lifting device (by moving the handle bar towards the transport device so that the lifting device

by pivoting the support wheels resting on the ground in the direction of the transport device, whereby the lifting bolt pivots in the direction of the transport device) into engagement with a lug on the base frame. The transport device can then be moved by rolling on the wheels and the support wheels.

[0055] According to a particularly preferred embodiment, it can be provided that the arrangement comprises a first external lifting device with a first lifting bolt according to the type described above (in which an axis of rotation of the at least one support wheel runs concentrically to a central axis of the crossbar) and a second external lifting device with a second lifting bolt according to the type described above (in which an axis of rotation of the at least one support wheel runs eccentrically to a central axis of the crossbar), wherein a first suspension lug is arranged or formed at a first end of the base frame with respect to a longitudinal extension of the base frame, wherein a second suspension lug is arranged or formed at a second end of the base frame with respect to a longitudinal extension of the base frame, wherein the first lifting bolt can be brought into engagement with the first suspension lug and the second lifting bolt can be brought into engagement with the second suspension lug in order to lift the transport device. The first suspension lug and the second suspension lug are preferably designed identically so that both external lifting devices can be used at both ends of the transport device.

[0084] Fig. 29 shows a further embodiment of a proposed transport device with wheels in storage position in a side view, and

[0085] Fig. 30 shows the transport device of Fig. 29 in a plan view.

[0086] Fig. 1 shows a first embodiment of a proposed transport device 1 in a side view, Fig. 2 shows the transport device 1 of Fig. 1 in a front view, and Fig. 3 shows the transport device 1 of Fig. 1 in a plan view.

[0087] The transport device 1 shown is used to transport goods 2, in particular plate-shaped goods 2, and comprises a base frame 3 on which the goods 2 to be transported can be arranged or are arranged (two plate-shaped goods 2 are shown in dashed lines as an example), a support device 4 arranged on the base frame 3 for supporting the goods 2 to be transported, in particular laterally, two wheels 5 arranged on the base frame 3, and a movement device 6 for moving the wheels 5 from a storage position to a driving position and vice versa. In the position of the movement device 6 shown, the wheels 5 are in the storage position, in which the wheels 5 are unloaded. The transport device 1 is parked in a stationary manner on a base U. Several parking devices 23 (in the form of feet or runners) are arranged on the base frame 3 of the transport device 1 shown, and the transport device 1 rests on the base U by means of the parking devices 23 (the load of the transport device 1 is therefore not supported on the wheels 5 in this position). In order to lift the transport device 1, which is parked stationary on the base U, with a forklift or pallet truck, insertion spaces E remain free between the base frame 3 and the base U, into which prongs or forks of a forklift or pallet truck can be inserted.

[0088] The base frame 3 comprises a storage device 24 on each side of the support device 4, wherein the goods 2 to be transported can be placed or placed on the storage devices 24. In the example shown, the base frame 3 has a frame with a longitudinal extension L and a transverse extension Q, wherein several struts 38 are arranged within the frame, which together with the frame form the storage devices 24. The two storage devices 24 are slightly inclined (by about 3°) from the horizontal starting from the center in the direction of the outer ends along the transverse extension Q of the base frame 3. This reduces the risk of the goods 2 placed on the storage devices 24 falling sideways from the storage devices 24. In the direction of the longitudinal extension L of the base frame 3, the base frame 3 is aligned essentially horizontally.

[0089] At both ends 3a, 3b of the base frame 3 in relation to the longitudinal extension L, a support wheel 20 is arranged on the base frame 3. The two support wheels 20 are each arranged essentially centrally on the base frame 3 in relation to the transverse extension Q of the base frame 3 and in the example shown are designed as rigid rollers (e.g. fixed rollers). At both ends 3a, 3b of the base frame 3 in relation to the longitudinal extension L, a suspension lug 35a, 35b is also arranged on the base frame 3. The suspension lugs 35a, 35b are designed the same and form engagement points for external lifting devices 30a, 30b described later.

[0090] In the illustrated position of the transport device 1 which is stationary on the ground U and in which the wheels 5 are in the storage position, the support wheels 20 are also unloaded, i.e. the load of the transport device 1 is neither supported on the wheels 5 nor on the support wheels 20 in this position.

[0091] The support device 4 arranged on the base frame 3 extends from the base frame 3 essentially vertically upwards and comprises a support frame 25. The support frame 25 of the transport device 1 shown comprises a plurality of support legs 26 arranged in pairs in an essentially A-shape. The struts 38 of the base frame 3 running in the direction of the transverse extension Q of the base frame 3 are arranged essentially at right angles to the support legs 26 running obliquely to the vertical, so that the goods 2 can be safely stored on the base frame 3 and a sideways falling of the goods 2 can be avoided.

[0092] As described above, the movement device 6 of the transport device 1 serves to move the wheels 5 from a storage position to a driving position and vice versa, wherein in the storage position the wheels 5 are unloaded and in the driving position the load of the transport device 1 is at least partially supported on the wheels 5. In the driving position of the wheels 5, the transport device 1 can be moved on the ground U, whereby the transport device 1 represents a mobile transport device. In the position of the movement device 6 shown in Figs. 1 to 3, the wheels 5 are in the storage position in which the wheels 5 are unloaded.

[0093] The movement device 6 of the transport device 1 shown comprises a pivot rod 7 which is rotatably mounted on the base frame 3 and which is arranged on the base frame 3 essentially transversely to the longitudinal extent L (i.e. essentially in the direction of the transverse extent Q of the base frame 3). A lever 8 and two wheels 5 spaced apart along the pivot rod 7 are arranged on the pivot rod 7 by means of brackets 9. The lever 8 and the fork-shaped brackets 9 are rigidly or non-rotatably connected to the pivot rod 7. The axes of rotation DR of the wheels 5 run between the forks of the brackets 9. The concentric axes of rotation DR of the wheels 5 run essentially parallel to the transverse extent Q of the base frame 3. The pivot rod 7 has a central axis MS which also runs essentially parallel to the transverse extent Q of the base frame 3 and thus parallel to the axes of rotation DR of the wheels 5. The concentric axes of rotation DR of the wheels 5 are eccentric to the central axis MS of the pivot rod 7. The central axis MS of the pivot rod 7 and the axes of rotation DR of the wheels 5 span a plane 44 running obliquely to the vertical 43, wherein the vertical 43 and the plane 44 running obliquely to the vertical 43 enclose a dead center angle TW.

[0094] By means of lever actuation of the lever 8 and the associated rotation of the pivot rod 7, the wheels 5 can be moved from the storage position to the driving position and vice versa. In order to move the wheels 5 from the storage position shown in Fig. 1 to the driving position, the lever 8 must be pivoted anti-clockwise (with respect to the lever position shown in Fig. 1) about the central axis MS of the pivot rod 7.

[0095] To facilitate the execution of this lever movement, the movement device 6 comprises a pulling device 10, which is arranged on the lever 8 in an articulated manner, in particular pivotable relative to the lever 8. In the embodiment shown, a connecting end 10a of the pulling device 10 is pivotally connected to a lever end of the lever 8, and an actuating end 10b of the pulling device 10 has a handle 11. For vertical support

the pulling device 10, the transport device 1 comprises a support device 12 arranged on the support device 4. In the example shown, a rod-shaped support device 12, which runs in the direction of the transverse extension Q of the base frame 3, is arranged on support legs 26 of the support frame 25 of the support device 4. The pulling device 10 comprises a pull rod 13 and a pull cable 14 connected to the pull rod 13, to the free end of which the handle 11 is attached.

[0096] To lock the pulling device 10 to the transport device 1, the pulling device 10 comprises a locking device 15. In the example, the locking device 15 is arranged on an end of the pull rod 13 facing the traction cable 14. The locking device 15 comprises a projection 17 (here in the form of a locking lug) which can be brought into engagement with a corresponding counter-projection 18 (here in the form of a locking hook) arranged on the transport device 1 for locking and can be disengaged to release the locking. The counter projection 18 is arranged here on support legs 26 of the support frame 25 of the support device 4 and is made of a folded sheet metal through which the traction device 10 or its traction cable 14 is guided, in that an opening 41 (e.g. elongated hole) is provided in the sheet metal hook through which the traction cable 14 is guided. The traction cable 14 can be pulled in the pulling direction Z (and thus the lever 8 can be actuated) until the projection 17 of the locking device 15 is in a position in which it can be brought into engagement with the counter projection 18. In this position, which corresponds for example to a lever position in which the wheels 5 are in the driving position, the projection 17 can then be brought into engagement with the counter projection 18 and the lever position can thus be locked. The folded sheet metal forming the counter projection 18 in the example simultaneously also forms a limit stop 42 which prevents the dead center (at which the center axis MS of the pivot rod 7 and the rotation axes DR of the wheels 5 intersect a common vertical) from being exceeded during further pulling on the pulling device 10 in the pulling direction Z.

[0097] In the illustrated embodiment, the pivot rod 7 (running in the direction of the transverse extension Q) is arranged off-center with respect to the longitudinal extension L on the base frame 3. Specifically, the pivot rod 7 is arranged off-center with respect to the longitudinal extension L on the base frame 3, starting from the center M of the longitudinal extension L of the base frame, by a distance A which is approximately 3% of the longitudinal extension L. This results in a first length L1 from the first end 3a of the base frame 3 to the center axis MS of the pivot rod 7 and a second length L2 from the center axis MS of the pivot rod 7 to the second end 3b of the base frame 3, wherein the second length L2 is greater than the first length L1 and the first length L1 and the second length L2 result in the longitudinal extension L.

[0098] Fig. 4 shows the transport device 1 according to Fig. 1 with wheels 5 in the driving position in a side view, Fig. 5 shows the transport device 1 of Fig. 4 in a front view, and Fig. 6 shows the transport device 1 of Fig. 4 in a plan view.

[0099] Starting from the position of the transport device 1 in Figs. 1 to 3, the pulling device 10 was pulled in the pulling direction Z (and thus the lever 8 was actuated) until the projection 17 of the locking device 15 was brought into a position in which it could be brought into engagement with the counter projection 18. This locked the pulling device 10 (and thus the lever position of the lever 8) relative to the transport device 1 and thus fixed the pivot position of the pivot rod 7. With this position of the pivot rod 7, the wheels 5 are pivoted so far relative to the base frame 3 that they are in the driving position and the transport device 1 can be moved on the ground U.

[00100] Due to the arrangement of the wheels 5 on the swivel rod 7, in which the rotation axes DR of the wheels 5 run eccentrically to the central axis MS of the swivel rod 7, the wheels 5 pivot about the central axis MS when the lever 8 is actuated by the pulling device 10. Starting from the storage position of the wheels 5 shown in Figs. 1 to 3, the swivel rod 7 with the wheels 5 arranged on it is thus rotated when the lever is actuated, whereby the wheels 5 are pivoted about the central axis MS until they rest on the ground U. By pivoting further in the same direction,

the transport device 1 is raised from the ground U and rests at least partially on the wheels 5, which are then in the driving position shown in Figs. 4 to 6. When moving from the storage position to the driving position, the transport device 1 is raised, whereby the weight of the transport device 1 acts at least partially on the wheels 5. In the driving position, the transport device 1 can be moved on the ground U, whereby the transport device 1 represents a mobile transport device.

[00101] Due to the off-center arrangement of the pivot rod 7 in relation to the longitudinal extension L of the base frame 3, when the traction device 10 is actuated and the transport device 1 is thereby raised, depending on the loading situation of the transport device 1, the transport device 1 tilts (around the point of contact of the wheels 5 with the ground U) in the direction of one of the two ends 3a, 3b of the base frame 3. In the example shown, the transport device 1 tilts minimally to the ground at the end 3b that is further away from the pivot rod 7, in this case at the end 3b at which the traction device 10 was also actuated.

[00102] When the wheels 5 were pivoted from the storage position to the driving position, the wheels 5 were not pivoted beyond the dead center, at which the center axis MS of the pivot rod 7 and the rotation axes DR of the wheels 5 would intersect a common vertical. When the towing device 10 is locked - as shown in Figs. 4 to 6 - the center axis MS of the pivot rod 7 and the rotation axes DR of the wheels 5 form a plane 44 running obliquely to the vertical 43, the vertical 43 and the plane 44 running obliquely to the vertical 43 enclosing a dead center angle TW. In order to prevent movement beyond the dead center, a limit stop 42 is provided, which in the example shown is formed from the folded sheet metal forming the counter projection 18. The limit stop 42 limits a movement of the pulling device 10 in the pulling direction Z, whereby when the position of the pulling device 10 is limited by the limit stop 42, the dead center angle TW is still greater than 0°, and thus the dead center cannot be exceeded.

[00103] Because the wheels 5 were not pivoted beyond the dead center, a lever effect is created in the driving position of the wheels 5 between the point of contact of the wheels 5 with the ground U and the pivot rod 7, and the weight of the transport device 1 supports pivoting of the wheels 5 back into the storage position. If the transport device 1 is heavily loaded and therefore heavily weighted, releasing the locking mechanism of the traction device 10 would result in an abrupt change of position of the wheels 5 from the driving position to the storage position and possibly an unintentional, abrupt setting down of the transport device 1 on the ground U. In order to counteract this unintentional movement, the movement device 6 comprises a damping device 19 in the form of an oil brake for dampening the movement of the wheels 5 from the driving position to the storage position. This is arranged between the lever 8 and the base frame 3 and has a dampening effect on the movement during a lowering movement of the transport device 1. The fastening points of the damping device 19 on the lever 8 and the base frame 3, which are not shown in detail in the figures, have an elongated hole so that the first phase of the lowering movement (i.e. while the fastening is being moved along the elongated hole) is still unbraked, which makes it easier to release the locking of the pulling device 10.

[00104] Fig. 7 shows a second embodiment of a proposed transport device 1 in a side view and Fig. 8 shows the transport device 1 of Fig. 7 in a front view. The wheels 5 are in the storage position. In comparison with the embodiment shown in Figs. 1 to 6, the pivot rod 7 is arranged further off-center in relation to the longitudinal extension L of the base frame 3, namely by a distance A that is approximately 15% of the longitudinal extension L (see Fig. 11). Furthermore, the transport device 1 shown here does not comprise a support wheel 20 at both ends of the base frame 3, but only one support wheel 20 is provided in the form of a steering roller, which is arranged on a pivot bracket 21, wherein the pivot bracket 21 is arranged on the base frame 3 so as to be pivotable relative to the base frame 3, and wherein the pivot bracket 21 is connected to the lever 8 by a connecting rod 22. The swivel bracket 21 is

The rotation axis DS of the swivel bracket 21 is pivotably mounted on the base frame 3.

[00105] Due to the described off-center arrangement of the swivel rod 7 and the swivel bracket 21 connected to the lever 8 by means of a connecting rod 22, when the lever is actuated by pulling on the pulling device 10 in the pulling direction Z, the swivel rod 7 pivots about the center axis MS of the swivel rod 7 and the swivel bracket 21 pivots about the rotation axis DS of the swivel bracket 21, whereby the swivel bracket 21 only starts to lift the transport device 1 when the greatest actuating force on the swivel rod 7 has passed. In other words, when the pulling device 10 is actuated, the transport device 1 is first lifted in the area of the wheels 5 and only then in the area of the support wheel 20.

[00106] Fig. 9 shows the transport device 1 of Fig. 7 during the movement of the wheels 5 from the storage position to the driving position in a side view. In this position of the transport device 1 it can be seen that it is already slightly lifted off the ground U in the area of the wheels 5, while in the area of the support wheel 20 it is still supported on the ground U by means of the parking device 23.

[00107] Fig. 10 shows the transport device 1 of Fig. 7 with wheels 5 in the driving position in a side view, and Fig. 11 shows the transport device 1 of Fig. 10 in a top view. In this position, the transport device 1 is completely lifted off the ground U and the weight of the transport device 1 rests on the wheels 5 and the support wheel 20. The pulling device 10 is locked relative to the transport device 1 by means of the locking device 15 and counter projection 18 and the dead center angle TW is greater than 0°, i.e. the dead center has not been exceeded.

[00108] Fig. 12 shows a further embodiment of a proposed transport device 1 with wheels 5 in storage position in a perspective view, Fig. 13 shows the transport device 1 of Fig. 12 with wheels 5 in driving position in a perspective view, and Fig. 14 shows the transport device 1 of Fig. 13 in a further perspective view.

[00109] Like the embodiment according to Figs. 1 to 6, the transport device 1 shown here comprises a swivel rod 7 arranged only slightly off-center and two support wheels 20 at both ends 3a, 3b of the base frame. However, the swivel rod 7 does not extend essentially along the entire transverse extension Q of the base frame 3, but the swivel rod 7 is shorter than the transverse extension Q and runs between two struts 38 of the base frame 3 that run parallel to the longitudinal extension L.

[00110] The support device 4 or its support frame 25 comprises a lifting beam 27 for lifting the transport device 1 by means of a hoist, with a crane eye 28 and four lashing eyes 29 being arranged on the lifting beam 27. To reinforce the support frame 25 of the support device 4, the support frame 25 comprises a reinforcing strut 48 running in the direction of the longitudinal extension L and two diagonal struts 49 which connect the crane eye 28 to the reinforcing strut 48 and ensure a uniform introduction of force into the support frame 25 starting from the crane eye 28.

[00111] Fig. 15 shows a detailed view of a damping device 19 in the form of an oil brake. This is arranged between the lever 8 and the base frame 3 and has a damping effect on the movement during a lowering movement of the transport device 1. The fastening points 50 of the damping device 19 on the lever 8 and the base frame 3 have an elongated hole, so that the first phase of a lowering movement of the transport device 1 (i.e. during the displacement of the fastening along the elongated hole) still takes place without braking, which makes it easier to release any locking mechanism of the pulling device 10.

[00112] Fig. 16 shows a detailed view of a counter projection 18. This is formed from a folded sheet metal which is arranged on support legs 26 of a support frame 25 of a support device 4. The counter projection 18 in the form of the folded sheet metal also forms a limit stop 42 which limits a movement of the pulling device 10 in the pulling direction Z. An opening 41 in the form of an elongated hole is formed in the limit stop 42,

through which the traction cable 14 of the traction device 10 is guided. However, a locking device 15 arranged on the traction device 10 does not fit through the opening 41, so that the limit stop 42 limits the movement of the traction device 10 in the traction direction Z.

[00113] Fig. 17 shows a detailed view of a pulling device 10 equipped with a locking device 15 comprising a pull rod 13 and a pull cable 14, wherein the locking device 15 is arranged at an end of the pull rod 13 facing the pull cable 14. Fig. 18 shows the locking device of Fig. 17 in an exploded view. The locking device 15 shown here comprises a middle part 51 formed in one piece with the pull rod 13 and two clamping plates 16. Screws 53 are guided through the clamping plates 16 and the middle part 51 and are screwed together with nuts so that the clamping plates 16, between which the middle part 51 is located, are screwed together. One end of the pull cable 14 is guided through a slot 52 in the middle part 51 into the middle part 51 and arranged between the clamping plates 16. To anchor the traction cable 14 in the locking device 15, the clamping plates 16 and the central part 51 of the locking device 15, which is formed in one piece with the pull rod 13, each have a recess 39 into which a cable end 40 of the traction cable 14, which is formed larger than a cable diameter of the traction cable 14, is inserted. Lugs formed on the clamping plates 16 and on the central part 51 together form a projection 17 of the locking device 15, which can be brought into engagement with a counter projection 18 to lock the traction device 10.

[00114] Fig. 19 shows a locking device 15 according to Figs. 17 and 18 during the locking process with a counter projection 18, and Fig. 20 shows the locking device 15 of Fig. 19 in a locked state. The counter projection 18 is formed from a folded sheet metal, which at the same time also forms a limit stop 42 in which an opening 41 in the form of an elongated hole is formed. A pull cable 14 of the pull device 10 is guided through this opening 41. By pulling on the pull device 10 in the pulling direction Z, a projection 17 of the locking device 15 is brought into a position in which it can be brought into engagement with the counter projection 18. By moving the pulling device 10 downwards (this movement is made possible by the opening 41 in the form of an elongated hole), the projection 17 is brought into engagement with the counter projection 18 and the pulling device 10 is locked.

[00115] In addition to the movement device 6, the transport device 1 can also be lifted with the aid of at least one external lifting device. Fig. 21 shows an embodiment of a first external lifting device 30a in a perspective view, and Fig. 22 shows the first external lifting device 30a of Fig. 21 in a front view. Fig. 23 shows an embodiment of a second external lifting device 30b in a perspective view, and Fig. 24 shows the second external lifting device 30b of Fig. 23 in a front view. Both external lifting devices 30a, 30b shown each comprise a handle bar 31, a crossbar 32 arranged on the handle bar 31 and running transversely to the longitudinal extension of the handle bar 31, and a lifting bolt 33a, 33b for lifting the transport device 1. Two support wheels 34 are arranged on the respective crossbar 32. To lift the transport device 1, the respective lifting bolt 33a, 33b can be brought into engagement with the base frame 3, preferably with at least one suspension lug 35a, 35b formed or arranged on the base frame 3, particularly preferably corresponding to the at least one lifting bolt 33a, 33b.

[00116] In the first external lifting device 30a with a first lifting bolt 33a, the axes of rotation DU of the support wheels 34 are concentric with a central axis MQ of the crossbar 32, and the lifting bolt 33a is arranged on a bolt holder 36 protruding from the crossbar 32. A first imaginary line 45 along the handle bar 31 to the central axis MQ and a second imaginary line 46 from the first lifting bolt 33a to the central axis MQ span a common plane and enclose an angle W1 of approximately 110°.

[00117] In the second external lifting device 30b with second lifting bolt 33b, the support wheels 34 are arranged on the crossbar 32 by means of wheel holders 37, and the rotation axes DU of the support wheels 34 are eccentric to the central axis MQ of the crossbar 32.

The second lifting bolt 33b is formed by the crossbar 32 itself. A first imaginary line 45 along the handlebar 31 to the central axis MQ and a third imaginary line 47 from the common axis of rotation DU of the support wheels 34 to the central axis MQ span a common plane and enclose an angle W2 of approximately 160°.

[00118] Fig. 25 shows an embodiment of a proposed arrangement comprising a transport device 1 partially placed on a step S, a first external lifting device 30a according to Fig. 21 and a second external lifting device 30b according to Fig. 23 in a side view, Fig. 26 shows the arrangement of Fig. 25 in a plan view, Fig. 27 shows the transport device 1 of Fig. 25 during lifting by means of the first external lifting device 30a and the second external lifting device 30b, and Fig. 28 shows the transport device 1 of Fig. 27 in the raised state.

[00119] In the position shown in Figures 25 and 26, the transport device 1 is partially placed on a step S. The transport device 1 rests on the step S with two parking devices 23. A first suspension lug 35a is arranged at a first end 3a of the base frame 3 and a second suspension lug 35b is arranged at a second end 3b of the base frame 3. Both suspension lugs 35a, 35b are designed identically and correspond to the shapes of the first lifting bolt 33a of the first external lifting device 30a and the second lifting bolt 33b of the second external lifting device 30b. To lift the transport device 1, the first lifting bolt 33a is brought into engagement with the first suspension lug 35a and the second lifting bolt 33b is brought into engagement with the second suspension lug 35b.

[00120] In the position of the arrangement shown in Fig. 27, the two lifting bolts 33a, 33b are already in engagement with the suspension lugs 35a, 35b and the transport device 1 is lifted by pivoting the handle bars 31 of the two external lifting devices 30a, 30b clockwise (this is indicated in Fig. 27 by the curved arrows).

[00121] In the position of the arrangement shown in Fig. 28, the transport device 1 is raised. The weight or load of the transport device 1 now rests on the support wheels 34 of the two external lifting devices 30a, 30b, and the transport device can be driven in the raised state by means of the support wheels 34 over the step S and set down again after the step S by pivoting the handle bars 31 of the two external lifting devices 30a, 30b in an anti-clockwise direction.

[00122] Fig. 29 shows a further embodiment of a proposed transport device 1 in a side view and Fig. 30 shows the transport device 1 of Fig. 29 in a top view. The wheels 5 are in the storage position. In comparison with the embodiment shown in Figs. 1 to 6, two pivoting rods 7, 7' spaced apart from one another in the direction of the longitudinal extension L are arranged on the base frame 3.

[00123] The movement device 6 of the transport device 1 shown here comprises a first pivot rod 7 with a first lever 8 arranged thereon and a second pivot rod 7', which is spaced apart from the first pivot rod 7 in the direction of the longitudinal extension L and has a second lever 8' arranged thereon. A first pulling device 10 is articulated on the first lever 8 and a second pulling device 10' is articulated on the second lever 8'. The two pulling devices 10, 10' are aligned in opposite directions so that the two pulling devices 10, 10° can be operated from both ends of the transport device 1. By providing several pivot rods 7, 7' and several pulling devices 10, 10' coupled thereto, even a heavily loaded transport device 1 can still be lifted manually.
