Description

The invention relates to a piece of furniture, in particular a cabinet, with at least one sliding door which is held and guided by a guide device.

A piece of furniture, in particular a cupboard, can advantageously be locked by means of sliding doors. To open a cabinet, the sliding doors are pushed aside and do not have to be rotated into the room against the user like rotating doors. On the other hand, space is also required for the sliding doors to be opened in which they can be parked.

From [1], US2014 / 150208A1 , A cabinet with a guide device is known, by means of which sliding doors can be folded and moved parallel to the side wall of the cabinet into a parking space. The space provided for the parking space inside the cabinet is no longer available for using the cabinet.

The 2], US8763205B2 discloses a cabinet with a plurality of sliding doors, each of which is held and guided by a drive device which can be displaced along guide rails, so that the sliding doors can be lifted off a cabinet opening and moved laterally. The drive devices include drives and drive arms which are connected to the sliding doors via connecting devices. The sliding doors of this cabinet are therefore not transported to a specially provided parking space, but are moved in front of an adjacent sliding door. With a cabinet with two sliding doors, the user can therefore slide one in front of the other sliding door. The opened sliding door stands therefore in front of the closed sliding door in the user's field of vision. In cabinets of this type, the sliding doors must therefore be precisely aligned and guided in order to avoid collisions during the displacement and to produce an advantageous appearance when the sliding doors have reached the end position.

Due to the relatively complex guidance of the sliding doors, which are lifted from the cabinet opening when opened and moved against the cabinet opening when closed and are moved in parallel outside this area, the guide device has various tasks which are hardly satisfactorily solved in the prior art. In addition to the precise guidance for avoiding collisions and for the desired alignment of the sliding doors, it would be particularly desirable if the sliding doors could be guided and held more stably, so that vibrations and noises can be avoided, in particular in the area of parallel guidance of the sliding doors. Furthermore, it would be desirable if the sliding doors reliably closed the cabinet opening after the closing process, so that exposed gaps and remaining play of the sliding doors can be avoided. Another disadvantage of known solutions is that the sliding doors can often not be moved completely away from the associated cabinet opening, after which access to the cabinet opening is hindered. A limited ability to move the sliding door also does not allow a maximum size of the cabinet opening to be realized.

The GB738486A discloses a guiding device for a car door which is lifted from an opening by means of levers and can subsequently be displaced along holding elements by means of rails which are connected to the car door, each of which is slidably held in one of the rails and connected to one of the levers.

The DE202005004059U1 discloses a guide system for a sliding door with a guide rail and a roller carriage guided along the guide rail, on which the sliding door is pivoted about a roller carriage axis.

The WO2004095997A1 discloses a room divider for a shower cubicle with a sliding door that connects flush to an adjacent room divider element in the closed state. The JP2009127199A discloses a piece of furniture according to the preamble of claim 1, with a door mechanism which allows a door connected thereto to be moved in front of an adjacent door.

The US2009230722A1 discloses an apparatus for supporting a sliding door which is movable between a closed position and a fully open position, comprising a door bracket for fixed attachment to the sliding door; a track mounted along an exterior of a vehicle and extending from a vehicle opening to a distal end, the length of the track from the opening to the distal end being less than that of the sliding door between the closed position and the full Open position through the route.

The present invention is therefore based on the object of providing an improved piece of furniture with at least one sliding door which can advantageously be displaced between an open position and a closed position by means of an improved guide device is.

In particular, a guide device is to be created by means of which a sliding door held therewith, or generally a flat separating element, can be precisely moved along a transport path which has at least one curve.

The guiding device should, in particular, allow the sliding area of the cabinet doors to be enlarged, thereby opening an associated cabinet opening completely and realizing the cabinet opening in the maximum size.

By means of the guide device, the sliding door held should be able to be kept as free of play as possible and be moved without noise. Furthermore, the sliding door should be displaceable by means of the guide device in such a way that a corresponding cabinet opening can be reliably closed.

The guide device should also have a simple structure and take up little space so that the cabinet space is available to the user without significant restrictions.

Furthermore, the guide device should be able to absorb the load of the sliding door in whole or in part.

A piece of furniture provided with the guiding device, in particular a cabinet, should therefore be able to be advantageously dimensioned, operated and used.

This object is achieved with a piece of furniture according to claim 1, which is provided with at least one improved guide device. advantageous Embodiments of the invention are specified in further claims.

When the sliding door is moved against the cabinet opening, the guide drive is moved into the interior of the cabinet and the guide lever is rotated. The sliding door can therefore be moved laterally into the end position and at the same time against the cabinet opening while the guide drive is moving. This allows the guide fitting to be guided past the guide drive and moved against the cabinet opening. The guide fitting is therefore moved further in the closing direction of the sliding door than the guide drive. When the guide drive exits the end area, the guide lever is turned back again, so that the guide fitting is guided past the guide drive in the other direction and the guide drive is pulled by the guide lever. In the opening direction of the sliding door, too, the guide fitting runs a further path than the guide drive.

The guide device thus allows due to the cornering of the guide drive and the rotation of the curved guide lever to move the guide fitting and thus the sliding door along the front of the cabinet over a wider area than the guide drive itself is moved. This allows the cabinet opening to be realized with the maximum size. Furthermore, the sliding door can be completely moved away from the cabinet opening, so that the user has unhindered access to the interior of the cabinet. By means of the curved guide lever, the guide fitting can thus be guided in front of the guide drive during the opening process of the sliding door and the cabinet opening can be opened completely.

According to the invention, it is provided that the drive body of the guide drive holds two guide rollers arranged one behind the other in the running direction and is additionally connected to the second end piece of the guide lever by a coupling spring.

The coupling spring is preferably a spiral spring or a cylindrical spring which is arranged in a recess within the drive body and is anchored with a first end piece in the drive body and with the second end piece in the guide lever. Preferably the coupling spring is in a e.g. cylindrical recess in the drive body arranged coaxially to the hinge pin, which is preferably rotatably mounted in the drive body. In this way, the coupling spring can be integrated into the drive body in a space-saving manner and coupled to it. The coupling of the drive, i.e. of the hinge pin and the coupling spring with the guide lever in a simple manner.

The guide drive is rotated as it passes through the end area, the coupling spring is tensioned accordingly and one Force or torque exerted on the guide lever. The second end piece of the guide lever, which is connected to the guide fitting, is rotated by the torque against the cabinet and the sliding door is pulled against the frame of the cabinet opening, as a result of which it is sealed.

According to the invention, the guide lever is curved against the opening direction of the sliding door or in the same direction as the end region of the guide channel. For example, the guide lever is L-shaped or crescent-shaped. Due to the curvature of the lever, in the end position of the guide drive when the first sliding door is open, it can engage the adjacent second sliding door on the edge and hold the first sliding door in front of the second sliding door.

The curve shape of the end region of the guide channel is preferably selected such that the guide drive is rotated to an angle which passes through the end region and lies in a range from 65 ° to 180 °. For example, the end region runs at least approximately in a quarter circle or semicircular arc. The curve can also run in a spiral and have a continuously reduced curve radius. The radius of the curve can be linear or non-linear, possibly logarithmic, along the end area. The curve radius can also be reduced linearly in a first curve area and non-linearly in a second curve area. The curve shape is chosen such that the desired rotation of the guide drive and thus a desired tension of the coupling spring results.

The guide channel can be formed by a single guide rail which is bent accordingly in the end region. However, this is associated with a correspondingly high outlay, if the cross-section of the guide channel is to be maintained when bending the guide rails.

A straight guide rail is preferably provided, to which a rail element connects, which is provided in a guide plate. The end region of the guide channel can advantageously be stamped into the guide plate. Alternatively, the guide plate is cast from metal or plastic. Using the guide rail and the guide plate, the guide channel can therefore be realized over the entire length with a constant channel cross section.

In a preferred embodiment, the sliding door or the guide fitting is provided with a door stop against which a first lever stop provided on the first end piece of the guide lever can be rotated when the guide drive exits the end region. In a further preferred embodiment, the guide drive has a drive stop against which a second lever stop provided on the second end piece of the guide lever can be rotated when the guide drive exits the end region. The drive stop can be easily formed by the drive body itself. These two configurations are preferably provided in combination with the door stop, the drive stop and the first and second lever stop, by means of which the range of rotation of the guide lever during parallel travel with respect to the sliding door or the guide fitting on the one hand and the drive on the other hand is limited.

The door stop and the first lever stop on the one hand and / or the drive stop and the second lever stop on the other hand are preferably provided such that after the guide drive has entered a part of the Guide channel that runs parallel to the front of the cabinet, or after the guide drive has entered the straight guide rail, the door stop is preferably free of play on the first lever stop and the drive stop is preferably free of play on the second lever stop. A rotation of the guide lever in one direction is therefore limited by the door stop and a rotation of the guide lever in the other direction is limited by the drive stop. In this position of the guide lever, the sliding door is therefore guided parallel to the cabinet door without lateral displacements perpendicular to the running direction and corresponding vibrations being able to occur.

In a preferred embodiment, it is provided that the door stop and the first lever stop and / or the drive stop and the second lever stop are each elastically mounted, designed to be elastic, or can be connected to one another via an elastic element. In this way, noises are avoided when the abovementioned stops meet. In addition, even when manufacturing tolerances occur, it is ensured that the sliding door is guided without play.

In a further preferred embodiment, the guide drive has at least one support roller which is supported on a runway running parallel to the guide channel and is preferably integrally formed on the guide rail and on the drive plate. This guide drive allows the load of the sliding door or a part thereof to be taken up and the sliding door to be guided along the guide channel or guide and support channel.

If, on the other hand, the guide drive mainly serves to guide the sliding door and for this purpose, for example, engages in the guide channel from below, is carried by the support roller ensures that the guide roller always remains engaged in the guide channel. This makes it possible to use a guide channel with channel walls which have the minimum height required for the guide rollers and therefore take up little space.

The guide rollers are preferably held by first bearing shafts, which project at least approximately vertically into the guide channel from above or from below. The at least one idler roller, on the other hand, is held by a second bearing shaft, which is oriented at least approximately horizontally.

The guide drive according to the invention with at least two guide rollers or with at least two guide rollers and at least one support roller fulfills various functions. By equipping with a coupling spring, it is possible to implement a closing function in addition to the management function or the management function and the carrying function. By means of the closing function, an additional force can automatically be exerted on the sliding door, by means of which the sliding door can be moved in a desired direction, in particular a direction perpendicular to the cabinet front, under the action of force.

With the guide device according to the invention and the guide drive according to the invention, it is thus possible to advantageously further develop a cabinet with sliding doors. The sliding doors held by the guide device are guided precisely and stably and are held stable in any position, especially in the end positions. The sliding doors can be completely moved away from the cabinet openings. In addition, the locking function is improved in such a way that cabinet openings of maximum size can be reliably closed.

The guide device can be arranged on the top or the bottom. In addition, one guide device each can be provided on the top and the bottom of the sliding door. If the guiding device e.g. is provided only on the top or the bottom of the cabinet, a complementary guide and support device is provided on the bottom or the top of the cabinet. If the complementary guiding and carrying device completely takes over the carrying function, the guiding device according to the invention can only provide the guiding function. As mentioned, however, the use of the at least one support roller is also advantageous in this case.

shows an embodiment of a cabinet 9 according to the invention with a

Cover plate 93 and side plates 94 as well as with two sliding doors 91, 92 each held by a guide device 6 according to the invention, each of which closes a cabinet opening 90 (see Fig. 1b ) are provided. A force vector F1 illustrates that the first sliding door 91 is pulled against the frame of the cabinet opening 90 by means of the guide device 6. The function of the guide device 6 connected to the second sliding door 92 is identical, which is why only the guide device 6 connected to the first sliding door 91 is described below.

Fig. 1b shows the cabinet 9 from Fig. 1a after the first sliding door 91 by means of the associated guide device 6 was lifted from the associated cabinet opening 90 and laterally moved in front of the second sliding door 92. The guide device 6 comprises a carriage 62 which has been guided along a guide rail 68 to an intermediate wall 95 and which is connected to the first sliding door 91 via a curved guide lever 63. The first sliding door 91 is held in front of the cabinet 9 by means of the guide device 6 during the parallel displacement in such a way that it cannot be displaced perpendicular to the running direction. When trying to move the sliding door 91 perpendicular to the running direction in one direction or the other, the guide device 6 exerts a corresponding counterforce F2 or F3.

Fig. 1b further shows that the first sliding door 91 held by the curved guide lever 63 has been completely moved in front of the second sliding door 92 and is aligned coaxially to the second sliding door 92 in this position. The cabinet opening 90, which has a maximum size, was therefore completely exposed. The curved guide lever 63 engages around the second sliding door 92 and can therefore hold the first sliding door 91 outside the area of the associated cabinet opening 90.

Fig. 2a shows the cabinet 9 with the guide device 6 in the configuration of FIG Fig. 1a after removal of the first sliding door 91 and a side wall 94 and a cut through the middle of the cover plate 93. The guide device 6 comprises the straight guide rail 68 which connects to a guide plate 69 into which the drive 62 has been inserted. The drive 62 is connected to a first end piece of the curved guide lever 63, the second end piece of which is connected to a guide fitting 61, from which the first sliding door 91 has been released. On the A complementary guiding and holding device 1 is provided on the underside of the cabinet 9, said device having a complementary drive 11 and associated complementary fittings 10. The complementary drive 11 can be displaced along a curved path in such a way that the complementary fitting 10 is displaced parallel to the guide fitting 61 when the sliding door 91 is displaced. The complementary guiding and holding device 1 optionally allows the sliding door 91 to be carried completely, which is why the guiding device 6 is not loaded by the weight of the sliding door 91 in this embodiment of the invention.

Fig. 2b shows the cabinet 9 in the configuration of Fig. 1b after removal of the first sliding door 91 and a cut through the center of the cover plate 93. The guide fitting 61 and the complementary fitting 10 were moved parallel to each other along identical curves k. The guide drive 62 is within the space opening 90 in the end stop near the intermediate wall 95, the guide fitting 61 being held in front of the second sliding door 92 by the guide lever 63.

Fig. 3a shows the guide device 6 in the configuration of FIG Fig. 2a with the guide plate 69 with a rail element 690, which connects to the guide rail 68. Through the guide rail 68 and the rail element 690, a guide channel 60 open at the bottom (see Fig. 3c ) formed in which the guide drive 62 is slidably held. The guide drive 62 is connected in an articulated manner to the guide fitting 61, from which the first sliding door 91 has been detached, via the guide lever 63 which is curved in an almost L-shape. A first end piece 63A of the guide lever 63 is through a first lever joint, ie through a first hinge pin 613 Guide fitting 61 rotatably connected. The guide plate 69 is provided with mounting holes 692 through which mounting screws 699 can be inserted into the cover plate 93.

Fig. 3b shows the guide drive 62, the guide lever 63 and the guide fitting 61, which from the guide device of Fig. 3a were taken without changing their mutual position. The guide drive 62 shown comprises a drive body 621 with two vertically aligned bearing shafts 626, of which guide rollers 622 are rotatably held. The drive body 621 is rotatably connected to a second end piece 63B of the guide lever 63 by a second swivel joint or by a second hinge pin 623. The guide fitting 61 and the guide drive 62 can therefore be rotated about parallel axes of rotation approximately in the same plane up to one stop each.

Fig. 3b shows that the guide drive 62 or the drive stop formed by the drive body 621 is rotatable against a second lever stop 632, which is formed by an angled element on the second end piece 63B of the guide lever 63. Fig. 3d shows that a first lever stop 631, which is provided on the first end piece 63A of the guide lever 63, can be rotated against a door stop 611, which is formed by an angled element on the guide fitting 61. Elastic elements 6351, 6352 are shown schematically, which can be inserted between the door stop 611 and the first lever stop 631 on the one hand and the drive stop 621 and the second lever stop 632 on the other hand. The elastic elements 6351, 6352, such as leaf springs or elastic plastics or natural rubber, make it possible for the first and second lever stops 631, 632 to strike the door stop 611 or dampen the drive stop 621 mechanically and acoustically and hold it together without play.

Fig. 3c shows the guide device 6 of Fig. 3a from below with a view into the guide rail 68 and the rail element 690 in the guide plate 69, through which a guide channel 60 is formed. The guide channel 60 runs through the guide rail 68 and inside the rail element 690 of the guide plate first along an elongated 90 ° curve, which is then followed by a further small curve of almost 90 °. This curve shape forms the end region 600 of the guide channel 60. In this end region 600, the guide drive 62 was moved into the cabinet opening 90 and rotated by approximately 135 °. By the rotation of the guide drive 62, which is connected to the guide lever 63 by a coupling spring 65 (see Fig. 4 ) a force or a torque will be transmitted to the guide lever 63 so that it is rotated further until the sliding door 91 is firmly against the frame of the cabinet opening 90.

Fig. 3d shows the guide drive 62, the guide lever 63 and the guide fitting 61 of Fig. 3b from underneath.

Fig. 4 shows the guide drive 62, the guide lever 63 and the guide fitting 61 of Fig. 3b in exploded view. The individually shown guide lever 63 is almost L-shaped or approximately crescent-shaped and has at the first end piece 63A the first lever stop 631 and a first joint opening 6301, into which the first joint pin 613 can be inserted, which leads through an opening 610 in the guide fitting 61 becomes. The guide fitting 61 is designed in the form of an angle. The first leg of the angle or of the guide fitting 61 forms a fitting plate 617 which can be connected to the sliding door 91 and which is provided with mounting openings 6171. On the second leg of the angle there are two Openings 610 are provided, into which the hinge pin 613 can optionally be inserted. With the guide fitting 61 of the first sliding door 91, the hinge pin 613 is inserted into the right opening 610 and with the guide fitting 61 of the second sliding door 91 the hinge pin is inserted into the left opening 610. The same guide device 6 can therefore be assembled in such a way that it can be used on both sides of the cabinet 9 for each of the sliding doors 91, 92.

At the second end piece 63B, the guide lever 63 has the second lever stop 632 and a second joint opening 6302, into which the second joint bolt 623 can be inserted, which is mounted in the drive body 621 of the guide drive 62 in a bearing cylinder 6211. Concentric to the bearing cylinder 6211, the bearing housing 621 has an annular receiving opening 6210, into which the coupling spring 65 shown can be inserted, which has a winding package 651 with two spring end pieces 651 and 652. The first spring end piece 652 can be inserted into a coupling opening 6215 in the drive body 610 (see Fig. 7b ). The second spring end piece 653 can be inserted into a spring opening 6305 in the second end piece 63B of the guide lever 63. The guide drive 62 is therefore connected to the guide lever 63 on the one hand by the second hinge pin 623 and on the other hand by the coupling spring 65. When the guide drive 62 rotates (to the right), the coupling spring 65 is tensioned and a torque is exerted on the guide lever 63.

Fig. 5a shows the guide device 6 in the configuration of the cabinet 9 of FIG Fig. 1a from below with the sliding door 91 connected to the guide fitting 61 in the end position of the guide drive 62, as also shown in FIGS Figures 3a-d is shown. The guide lever 63 was moved together with the guide drive 62 into the cabinet opening 90 and rotated counterclockwise, whereby the guide fitting 61 was guided to the right against the cabinet 9. The coupling spring 65 has been tensioned by the rotation of the guide drive 62 as it passes through the end region 600 of the guide channel 60, which is why a corresponding torque M1 acts on the guide lever 63. A corresponding force F1 is transmitted through the guide lever 63 to the guide fitting 61, with which the sliding door 91 is pulled almost vertically against the cabinet 9.

In Fig. 5a the distance d1 is also shown, by which the guide fitting 61 was guided past the guide drive 62 to the right.

Fig. 5b shows the guide device 6 of Fig. 5a in the process of opening the sliding door 91 shortly before the guide drive 62 exits the guide plate 69 and enters the guide rail 68. The sliding door 91 has been lifted off the cabinet opening 90 and the guide fitting 61 has already been guided past the guide drive 62 to the left.

Fig. 5c shows the guide device 6 of Fig. 5b after the guide drive 62 has entered the shortened guide rail 68 and moved to the end stop on the intermediate wall 95. The first sliding door 91 has been completely moved away from the associated cabinet opening 90 and moved in front of the second sliding door 92. The guide fitting 61 is held in front of the guide drive 62 by the distance d2 by the curved guide lever 63. When the first sliding door 91 is displaced in the direction of the guide rail 68, the guide fitting 61 has traveled a distance d = d1 + d2 more than the guide drive 62.

After entering the guide rail 68, the guide drive 62 is aligned parallel to the longitudinal axis x of the guide rail 68. The second lever stop 632 bears on the drive stop or on the drive body 621 and cannot be turned further to the left in the direction R2 shown. At the same time, the first lever stop 631 abuts the door stop 611 and can no longer be turned to the right in the opposite direction R1. The guide lever 63 is thus held in rotation by the door stop 611 and the drive stop 621 in both directions R1 and R2. The sliding door 91 can therefore only be moved axially along a displacement axis y, which runs parallel to the longitudinal axis x of the guide rail 68. Displacements perpendicular to the displacement axis y as well as corresponding vibrations and noises are excluded.

Fig. 6 shows the guide device 6 in a preferred embodiment from below with a view approximately along the longitudinal axis x of the guide rail 68. In this embodiment, the guide drive 62 is provided with a support wheel 628, which can roll on a horizontally aligned catwalk 688, 698, which is additionally on the Guide rail 68 and the guide plate 69 is provided running parallel to the guide channel 60. The drive body 621 has an additional holding part 6218, which holds a second bearing shaft 627, by means of which the supporting wheel 628 is rotatably mounted (see also Fig. 7a ). The guide wheel 62 is always held at the same height by the supporting wheel 628, thereby ensuring the constant engagement of the guide rollers 622 in the guide channel 60. It is thus possible to use a guide channel 60 or a guide rail 68 and a rail element 690 which have only a small wall height. In addition, the guide drive 62 can support the load of the sliding door 91 or a part thereof.

Next shows Fig. 6 that the second lever stop 632 is not provided in one piece on the guide lever 63 in this embodiment. Instead, a cylindrical lever stop 632 is fastened to the guide lever 63 by means of a rivet. The cylindrical lever stop 632 is preferably made of an elastic material, so that a play-free connection can be realized and noises during operation of the guide device 6 are avoided. The door stop 611 and the first and second lever stops 631, 632 can therefore be formed in one piece or fastened in some other way.

Fig. 7a shows this from the guide device 6 of FIG Fig. 6 removed guide drive 62, which has 2 guide rollers 622 and a support roller 628, which are held by first and second bearing shafts 626, 627.

Fig. 7b shows the guide drive 62 of FIG Fig. 7a with a section along the line AA, which runs through the receiving opening 6210 for the coupling spring 65 and through the coupling opening 6215, in which the first spring end piece 652 is anchored. The second spring end piece 653, like the second hinge pin 623, protrudes from the receiving opening 6210.

The guide device 6 can also be developed in such a way that individual device parts, in particular the drive stop 621, the door stop 611, the first lever stop 631 and / or the second lever stop 632, are adjustable, so that the areas in which the guide fitting 61 against the guide lever 63 and the guide drive 62 can be rotated against the guide planes 63, can be adjusted. It can also be provided that the bearing shaft 627, which holds the support wheel 628, can be displaced in parallel in height. For example, the Bearing shaft 627 are stored in a carriage which is displaceable along the holding part 6218.
