Title: Universal guide device for sliding doors of a piece of furniture

description

The present invention relates to a universal guide device for sliding doors of a piece of furniture according to the preamble of claim 1, which has at least one rod that can be fixed to a furniture body. The sliding door is slidably mounted on the rod via at least two rollers.

Guide devices of the generic type are known in many embodiments. A guide device in the lower and a further guide device in an upper end region of the sliding door element are usually required for mounting a sliding door element on a piece of furniture. Likewise, two guide devices, namely one in an upper region and one in a lower region of the furniture body, are usually used on the furniture body in order to enable the sliding door to be moved securely.

A guide device for sliding doors is known from EP 1 057 963 A2, which has a guide rail which has a C-shaped fastening groove in its central cross-sectional area for receiving fastening means. Guide grooves are provided above and below the fastening groove in order to guide rollers. However, such a guide device is only conditionally suitable for heavy sliding doors, such as glass doors in particular.

It is therefore an object of the present invention to provide a guide device for sliding doors, in particular for glass doors, which provides a simple and stable structure with inexpensive manufacturability and is suitable for various types of installation.

This object is achieved by a guide device with the features of claim 1. Advantageous further developments are the subject of the subclaims.

The guide device according to the invention comprises at least one guide element which is fastened to a furniture body by means of holding elements and at least two rollers which are fastened to the sliding door at the same time via fastening elements. The sliding door is slidably mounted on the guide element via the rollers. According to the invention, the guide element is designed as a cylindrical rod and the rollers have such a tread that the tread always lies completely on the rod at the point of contact between the roller and the rod. In other words, the rollers have a partially circular shape in section. This provides a simply constructed and stable guide device, which is particularly useful for heavy sliding doors such. B. sliding glass doors is suitable. The guide device consists of simply constructed parts, so that it can be produced relatively inexpensively. Furthermore, an unintentional unhooking of the sliding doors is not possible with such a design using an upper and lower rod.

The guide device according to the invention preferably has two cylindrical rods. One of the rods is preferably arranged in an upper region of the furniture body and the other rod is fastened to the furniture body in a lower region. This enables the sliding door to be guided in a particularly secure manner. According to another preferred embodiment of the present invention, two rods are arranged adjacent to one another, either on an upper part of the furniture body or on a lower part of the furniture body. As a result, the sliding door is only guided on an upper or lower area and the opposite area of the sliding door is exposed relative to the furniture body. Nevertheless, the sliding door is safely stored and guided on two parallel bars.

The guide device preferably has one or more continuously adjustable stops in order to prevent the sliding door from being inadvertently pushed off the guide device. The stop or stops are particularly preferably attached to the rod.

The continuously adjustable stops are designed so that they form a closed annular area which is pushed onto the rod. Starting orthogonally from the ring-shaped body of the stops is a projection that forms a soft stop on one side for the guide rollers of the sliding doors. At the same time, there is a threaded hole in the projection into which a grub screw is inserted. By tightening the grub screw, the stop is fixed on the rod. This stop can also be continuously adjusted by simply loosening the grub screw.

Each roller is preferably fastened to the sliding door by means of a fastening element. The fastening element is guided through a through opening formed in the sliding door. These are preferably punctiform fastenings which are flush with the glass pane on the outside of the sliding door. In this exemplary embodiment, the fastening element is an integral part of the structure of the roller. This prevents another additional type of fastening, which is particularly aimed at ensuring that no additional components need to be used when using glass doors. The through opening within the sliding door can be designed in a step-like manner or it is also possible for a conical area with a larger diameter to adjoin a cylindrical area toward the outside of the sliding door. Because of this shape, the fastening element with a complementary shape is used within this through opening. The outside of the fastener is flush with the outside of the sliding door.

The roller is constructed in such a way that the tread has a rubber-like convex shape, the fixed axis, which is connected to the fastening element, being mounted relative to the rotatable part of the roller via a bearing.

The cylindrical rods of the guide device are particularly preferably arranged on the outside of the furniture body. This enables the sliding door to be made larger than an opening provided in the furniture body. The rod is particularly preferably attached to a surface of the front of the furniture body or to upper or lower surfaces (surfaces parallel to the floor).

According to a further preferred embodiment of the present invention, the rod is attached to the furniture body at an angle. As a result, the sliding door can also be easily guided inside the furniture body. However, the rods can also be attached to the furniture body using holding elements. The holding elements for the rods are preferably designed such that they only partially grip around the rods. The holding elements particularly preferably grip around the rod in such a way that the holding elements do not interfere with the running of the rollers on the rod. In other words, the area of the rod on which the rollers run is not covered by the holding elements. When the holding elements are designed to connect a plurality of furniture bodies to one another, the holding elements can also completely encompass the rods.

According to the invention, if there are no bores arranged in the running rail or the like or a two-part design of the actual running rail receptacle after connecting the holding element, for example on a wall, the individual adjustment bearings of the individual holding elements assigned to a running rail or the like can be aligned that they form aligned support points for the non-positive support of the respective track mountings. For this it is only necessary to recognize the different distance of the individual adjustment bearings from the substructure and to arrange the individual adjustment bearings in alignment with one another. A holding element preferably consists of a fastening element and a running rail holder (rod holder).

The fastening member connected to the substructure is preferably designed as a pot-like fastening bush, which rests with its pot bottom of the substructure, so that the adjustment bearing can be rotatably supported in an internal thread of the fastening bush with a complementary external thread. This opens up the possibility, after connecting the fastening bushing to the substructure, of changing the distance of the adjustment bearing, which is preferably in the form of an adjusting disk, from the substructure, the Surface of the adjustment disk facing away from the adjustment disk forms an adjustment surface adjacent to the running track receptacle. This ensures - when using track receptacles of the same type - an exactly aligned arrangement of the track receptacles of the holding elements is guaranteed.

In a further embodiment of the invention, the wall of the pot-like fastening bush has an external thread, onto which a union bell can be screwed by means of a complementary internal thread.

The running track receptacle itself consists of a holding area receiving the running track, the supporting or holding rod and a hollow cylindrical extension which is connected to the holding area and is directed against the substructure and which is supported with a counter surface, preferably with an annular supporting surface, on the adjusting surface of the adjusting bearing. Depending on the local conditions, track mountings can be used in which the hollow cylindrical extension directed against the substructure has different lengths, so that tolerances can be compensated for.

In an internal thread of the hollow cylindrical extension there is a grub screw that can be adjusted against the running rail or the supporting or holding rod, by means of which the running rail or the carrying or holding rod can be clamped in a force-locking manner with respect to the holding area.

The union bell is fixed to the hollow cylindrical extension of the running rail receptacle in such a way that the union bell is rotatably and axially immovably fixed to the running rail receptacle by means of a clamping ring encircling an outer groove of the hollow cylindrical extension of the running rail receptacle. bell engages with a flange between a shoulder on the outer wall of the hollow cylindrical extension and the clamping ring. On the one hand, this type of fastening enables the union bell to be screwed onto the external thread of the fastening element designed as a pot-like fastening bush, and on the other hand fixes the distance between the running rail receptacle and the adjustment bearing.

The holding area of the running track receptacle can be designed differently; it can encompass the rail or the support or support bar by a little more than half the circumference or completely. An additional fixing of the running rail or of the supporting or holding rod with respect to the rail clamping profile can take place in that the rail clamping profile has a threaded hole for receiving a grub screw.

With reference to the above-described invention, the term “running rail” is to be understood as a rail or rod on which sliding elements of various types, for example rolling, can be guided. However, the above-described clamp holders can also be used for rails that only have a supporting function, for example for The clamp holders are also suitable for fastening, for example, grip elements which have been defined as holding rods.

According to a further advantageous embodiment of the present invention, a second guide element is designed as a U-shaped rail, in which one end of the sliding door is guided. This enables a particularly stable attachment of the sliding door to the furniture body. However, the U-shaped rail increases the friction compared to the use of the rollers. In order to enable the sliding door to be moved as quietly as possible, the rollers are preferably constructed in several parts, the running surface being made of plastic.

The sliding door is particularly preferably designed as a sliding glass door.

A first exemplary embodiment according to the present invention is described below with reference to FIGS. 1 to 4.

As shown in FIG. 1, a guide device has two guide elements (running rails) which are designed as cylindrical rods 6. A sliding door 1 is slidably mounted on the rods 6 via four rollers 3. The rollers 3 are fastened to the sliding door 1 by means of fastening elements 5. The sliding door 1 is designed as a glass door and has through openings through which the fastening elements 5 are inserted in order to fasten the rollers 3 and at the same time the sliding door 1.

The through openings within the glass door can be designed as a stepped bore or as a bore with a cylindrical extension and a conical area. The fastening element 5, designed to be complementary to this, is inserted into the bore with the aid of a glass protector 54 and thus fastened against the fixed part 56 of the roller 3. The fastening element is fastened by means of a connecting screw 52, which is screwed into a threaded bore within the fixed part 56 with its thread, which is not described in more detail.

The fastening element 5 is shown in more detail in FIGS. 19 and 20. The fastening element 5 has a through bore 57 in its base, which can be designed as a cylinder bore or as an elongated hole. A cylindrical region 59 is adjoined by a conical shear area 66 at the fastener 5. A blind bore 60 is made within the fastening element 5, at the bottom of which the through bore 57 is located. In the area of the conical area 66, the fastening element 5 is closed by a closure cap 62. The closure cap 62 has an undercut 63 in which a spring element is introduced. This spring element in turn nestles in an undercut 61 of the fastening element 5. The closure cap for dismantling the glass pane can thus be removed in a simple manner.

A further embodiment of a fastening element 58 is shown in FIG. 22. The geometrical structure of the fastening element is identical to that of the fastening element 5 in terms of its outer dimensions. However, the fastening element 58 is made in one piece and has a threaded shoulder 64 following the cylindrical region 59. The threaded neck 64 is screwed into the fixed part 56 of the roller 3. In order to be able to screw the fastening element 58 into the fixed part 56, there are tool attachments in the form of bores 65 on the outside of the fastening element 58.

As shown in FIG. 1, the two rods 6 are arranged on the furniture body 2 in such a way that one rod is attached to an upper region of the furniture body 2 and the second rod to a lower region of the furniture body 2. The rods 6 are fastened to the furniture body 2 by means of holding elements 7 or 17. As can be seen in particular from FIG. 1, a stop 13 with an elastic element 14 is provided on each of the two upper ends of the upper rod 6 in order to limit the displacement of the sliding door 1. The adjustable stop 13 is attached directly to the rod 6 and limits the displacement of the rollers 3 to the right or left. The adjustable stop 13 consists of a ring 24, on which a projection 23 is formed orthogonally. Within the ring 24 there is a through bore 20 for receiving the rod 6. A threaded bore 22 is provided in the projection 23, which extends obliquely to the central axis of the stop 13. In this threaded bore 22, a grub screw 21 is screwed to fasten the stop 13 on the rod 6. On one side of the projection 23 there is an elastic element 14 for limiting the running path of the rollers 3. For a pleasing appearance, the stop 13 has a bevel 25 on the projection 23. The structure of the stop 13 can be seen in FIGS. 17 and 18.

As shown in particular in FIGS. 2 and 3, the holding element 7 consists of three parts, namely a holding part 8, which has an external thread and a receiving area 9 for the rod 6 (see FIG. 3), a base part 10, which on the Furniture body 2 is fastened, and a lock nut 11. The base part 10 and the lock nut 11 are screwed onto the external thread area of the holding part 8. The rod 6 is fixed in the receiving area 9 of the holding part 8 by means of a grub screw 12 (cf. FIG. 3). The holding element 7 according to the invention in particular enables a height adjustment of the rod 6 by screwing the holding part 8 into the base part 10 or unscrewing it from the latter. As a result, the distance between the rod 6 and the furniture body 2 is changed. The final position of the holding element 7 can then be secured with the lock nut 11. This enables the rod to be aligned in a simple manner even after assembly and by the customers themselves.

A second embodiment of a holding element 17 is shown in FIGS. 9 to 12. The holding element 17 consists essentially of a running track receptacle 26, which is supported indirectly on a base part 29. The base part 29 is non-positively connected to an arbitrary substructure (not shown) by means of a fastening screw 18. Essential additional components of the holding element 17 are an adjustment bearing 31 and a coupling bell 19.

The base part 29 to be connected to the base construction is designed as a pot-like fastening bush, the pot base 30 of which rests on the substructure, not shown. A wall 67 (see FIG. 13) of the base part 29 has an internal thread 44 and an external thread 45. An adjustment bearing 31, which is designed as an adjustment disk 32, can be screwed into the internal thread 44. The running rail receptacle 26 has a hollow cylindrical extension 34, which forms a support sleeve 33 and is supported with an annular support surface 37 on an adjustment surface 37 of the adjustment bearing 31.

The support is provided by a cap 19, which is rotatably and axially immovably fixed to a flange 40 on an outer wall 68 of a hollow cylindrical extension 34. The fixing takes place on the one hand by supporting the flange 40 on a shoulder 35 of the hollow cylindrical extension 34 and on the other hand by means of a clamping ring 41 which surrounds a groove 39 of the hollow cylindrical extension.

The defined support of the annular support surface 38 of the support sleeve 33 on the adjustment surface 37 of the adjustment bearing 31 is carried out by screwing the coupling bell 19 onto an external thread 45 of the base part 29 (see FIG. 13).

The fixing of a running rail or rod, not shown, within the holding area 27 of the running rail receptacle 26 can be done by a Grub screw 43, which is screwed into an internal thread 42 of the hollow cylindrical extension 34. Alternatively, a grub screw 43 can be inserted into a threaded bore 28 in the holding area 27.

As shown in FIGS. 10 to 12, various configurations of the holding area 27 are conceivable.

The mounting of the holding element 17 is carried out by non-positively connecting the fastening member 18 to the respective substructure, the adjustment bearings 31 screwed to the fastening member 18 subsequently being aligned. Subsequent screwing of the coupling bell 19 with the fastening member 18 until the support sleeve 33 rests on the adjustment bearing 31 results in the non-positive clamping of the running track receptacle 26.

As shown in particular in FIG. 1, the rods 6 are fastened via the holding elements 7 or 17 to an upper region (upper side of the furniture) or lower region (lower side of the furniture) of the furniture body 2. This makes it possible for the sliding door 1 to be arranged at only a small distance h from the open area of the furniture body 2 (cf. FIG. 3).

As can also be seen from FIGS. 2 and 3, the receiving area 9 of the holding part 8 for receiving the rod 6 is designed in such a way that it has two arc-shaped arms which protrude beyond a central axis XX of the rod 6. As a result, the rod 6 cannot be removed upwards or downwards from the holding elements 7 or 17, but must always be guided out of the holding elements 7 in the direction of its longitudinal axis XX. As can further be seen from FIG. 3, the distance between the sliding door 1 and the furniture body 2 can be changed in a simple manner by arranging washers between the fastening element 5 and the rollers 3.

A second exemplary embodiment according to the present invention is described below with reference to FIG. 5. The same or functionally the same parts are denoted by the same reference numerals as in the first embodiment.

The second exemplary embodiment essentially corresponds to the first exemplary embodiment. In contrast to the first exemplary embodiment, the rod 6 of the guide device is fastened to a front region of the furniture body 2 via the holding elements 7. As a result, the sliding door 1 can have smaller dimensions than in comparison with the first exemplary embodiment. Furthermore, the distance between the sliding door 1 and the furniture body 2 can be adjusted to a certain extent by the holding element 7. In comparison with the first exemplary embodiment, the receiving area 9 of the holding part 8 is furthermore rotated by 90 °, so that the open section of the receiving area 9 points upward again, so that there is no obstruction of the roller 3 when rolling via the holding element 7. Otherwise, the second exemplary embodiment corresponds to the first exemplary embodiment, so that reference can be made to the description there.

FIG. 6 shows a guide device according to a third exemplary embodiment of the present invention. Identical or functionally identical parts are identified by the same reference symbols as in the exemplary embodiments described above. As shown in FIG. 6, in contrast to the previous exemplary embodiments, the rod 6 is fastened to an angle 16, which in turn is fastened to the furniture body 2. The angle 16 is fastened inside the furniture body. As in the second exemplary embodiment, the rod 6 is then fastened to the forward-facing region of the angle 16 via holding elements 7. In the lower area of the furniture body 2, a U-shaped rail 15 is arranged, in which the lower part of the sliding door 1 is guided. Thus, a rod 6 and a U-shaped rail 15 are provided as guide elements in the third embodiment. It should be noted that the U-shaped rail 15 can also be arranged in the upper area of the furniture body 2 and the rod 6 for this purpose can be arranged in the lower area of the furniture body 2. As a result of this embodiment of the invention shown in FIG. 6, it is in particular also possible for the sliding door 1 to be guided inside the furniture body 2, so that it does not protrude over the furniture body 2.

FIG. 7 shows a guide device according to a fourth exemplary embodiment of the present invention. Identical or functionally identical parts are identified by the same reference symbols as in the exemplary embodiments described above.

In contrast to the previously described exemplary embodiments, in the fourth exemplary embodiment two rods 6 used as guide elements are arranged directly adjacent. This makes it possible for the two guide rods 6 to be arranged, for example, only on an upper or lower region of the furniture body 2 and thus for only an upper or lower end of the sliding door 1 to be fixed on the furniture body 2. The other end of the sliding door 1 can be designed without a guide device. As shown in FIG. 7, the rollers 3 are guided on the lower rod 6 in the lower region of the rod. Of course, the rollers 3 of the lower rod 6 can also be guided on the upper area thereof.

FIG. 8 describes a guide device according to a fifth exemplary embodiment of the present invention. Identical or functionally identical parts are designated with the same reference symbols as in the previous exemplary embodiments.

As shown in FIG. 8, an angle 16 is fastened on an outer area of the furniture body 2, more precisely on the upper surface of the furniture body. The rod 6 is again fastened to the angle 16 via holding elements 7. The twisting of the angle 16 results in a wide range of design options for arranging the guide device according to the invention. Otherwise, the fifth embodiment corresponds to the previously described embodiments, so that a further description can be omitted.

The present invention thus relates to a guide device for sliding doors of a piece of furniture, in particular for sliding glass doors with a high weight. The guide device comprises at least one guide element designed as a cylindrical rod 6 and at least two rollers 3 which are fastened to the sliding door 1 via fastening elements 5. The rod 6 is fastened to the furniture body 2 via holding elements 7. The rollers 3 have a tread 4 such that the tread 4 lies completely on the rod 6 at the point of contact with the rod 6.

Instead of the holding element 7 described in FIGS. 1 to 8, the alternative holding element 17 can of course also be used. As already mentioned above, the roller 3 also forms the connection to the sliding door 1 via the fastening element 5. As a result, fewer individual parts are required and, at the same time, the visible area of the sliding door 1 is not impaired. The roller 3 is composed of two half-shells 49 and 50. The half-shell 50 is screwed into the half-shell 49. After the half shells 49 and 50 are screwed together, the tread 4 is embedded between their free ends. The tread 4 is preferably made of a rubber-like material in order to ensure that the sliding door 1 runs silently. A subsequently fixed part 56 is then screwed into the half-shell 50. In the part 56 there is a bearing 51, the outer ring of which is supported in the half-shell 49. The cage of the bearing 51 is mounted on the fixed part 56. The bearing 51 is held by a locking ring 69 on the fixed part 56.

The fixed part 56 has a projecting area 70 which protrudes from the roller 3. Inside the fixed part 56 there is a threaded hole, not shown. In order to connect the sliding door 1 to the roller 3, the sliding door 1 is brought into contact with the glass protection 55 with the aid of a glass protection 55 which bears against the outer surface of the projecting area 70. The fastening element 5 is inserted within the through opening located in the sliding door 1. A connecting screw 52 is used for the non-positive and positive connection of the holding element 5 and thus clamping the sliding door 1 to the fixed part 56. For a clean end of the holding element 5, the outer end of which is flush with the surface of the sliding door, a closure cap in the form of a closure element 53 is inserted into the fastening element 5. With such a construction, the roller 3 is connected directly to the sliding door 1 via the fastening element 5.
