Description

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

Sliding doors can be used to separate rooms in a building or lock cabinets. To open a cabinet, the sliding doors are pushed aside and do not need to be turned into the room like revolving doors. On the other hand, space is needed for the opening sliding doors, where they can be parked.

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

The 2], US8763205B2 discloses a cabinet having a plurality of sliding doors that are held and guided by guide rails slidable drive devices, so that the sliding doors can be lifted from a cabinet opening and moved laterally. The drive devices include drives with drive arms, which are connected via a respective connecting device with the sliding doors. The sliding doors of this cabinet are therefore not transported in a specially designated parking space, but moved in front of an adjacent sliding door. For a cabinet with two sliding doors, the user can therefore push one in front of the other sliding door. So that Sliding doors can be moved in the manner described by the guide drives, a rail device is required, which is adapted to move the drive or drive modules of the drive in appropriate tracks.

Rail systems or rail devices are usually provided by the manufacturer of the drives and rails in dimensions that are required for the final product. If the rail devices comprise only straight rail elements, it is also possible for the furniture manufacturer to cut them if necessary. This is hardly possible with complex rail systems that have curve shapes or that have combined rail shapes with curves and straight lines.

During installation, the prefabricated elements of the rail system are assembled piece by piece. Subsequently, at least one drive is inserted into the rail device. This assembly of the entire guide device causes considerable effort and requires appropriately trained personnel.

The present invention is therefore based on the object to provide an improved rail device for a guide device. Furthermore, a guide device is to be provided which comprises such a rail device, and a piece of furniture with at least one sliding door, in particular a cabinet which is equipped with such a rail device or guide device.

The rail device should be able to be adapted continuously with little effort to the dimensions of a cabinet. Furthermore, furniture and cabinets, which have different dimensions, can be retrofitted with little effort with such a rail device or guide device.

The rail device should be simple and can be manufactured at low cost. In particular, sections of the rail device having curves can be advantageously produced.

The guide device provided with the rail device should be mounted with reduced effort and the dimensions of the cabinet can be adjusted. Any adjustments should be made with minimal effort.

This object is achieved with a rail device, a guide device and a piece of furniture, in particular a cabinet, which have the features mentioned in claim 1, 12 and 14 respectively. Advantageous embodiments of the invention are specified in further claims.

The rail device is provided for a guide device having at least one drive, by means of which a sliding door can be displaced and displaced along a guide channel provided in the rail device, which extends through an at least partially straight first rail part and at least one adjoining it at least partially along a curve extending second rail part is formed.

According to the invention, bearing elements are provided which engage in one another in a form-fitting manner and by which the second rail part is held displaceable parallel to a longitudinal axis of the first rail part. Furthermore, fastening means are provided, through which the second Rail part at a selected position with the first rail part is connectable.

By moving the second rail part relative to the first rail part, the guide track can thus be selectively extended or shortened and adapted to the dimensions of a cabinet. If second rail parts are slidably provided on both sides of the first rail part, the guide rail can be optionally extended or shortened on both sides.

The parts of the rail device must therefore not be assembled according to the cabinet dimensions and then assembled sporadically. The rail device or preferably the entire guide device with one or more drives can already be delivered pre-assembled and assembled by the furniture manufacturer as a unit. After or during assembly of the rail device or the guide device, the second rail parts provided on each side of the first rail part can be displaced in order to lengthen or shorten the guide rail on one or both sides.

The inventive solution therefore makes it possible to mount the rail device or even the complete guide device in a single operation within a very short time and without special training of the staff.

The slidable mounting of the rail plate can be done in various ways, wherein it must be ensured that the first and the second rail part at the ends facing each other, i. are always aligned coaxially to each other in the transition region.

This is achieved particularly advantageously by providing that the first and the second rail part in the Overlap transition region of the guide channel and at least on one side of the guide channel positively and against each other slidably engage each other.

The overlapping parts of the first and second rail part preferably adjoin in common on at least one side of the guide channel and each form a tread part for a guide element guided in the guide channel. In the transition from the first to the second rail part and vice versa, the guide element, e.g. a leadership role, therefore always guided by at least one of the two tread parts.

Preferably, the second rail part, which forms the second channel portion and has a first and a second channel wall, is part of a plastic or metal-made rail plate, which extends on the first side of the guide channel first plate member and extending on the second side of the guide channel second Plate part has. The use of this rail plate makes it possible to produce the second rail part precisely with any curve. Further, the rail plate can be advantageously coupled to the first rail part or associated auxiliary elements, such as auxiliary rails. Furthermore, the mounting plate preferably has options for mounting a collection device.

The first and the second rail part are preferably connected together at least on a first side of the guide channel by a first auxiliary rail, along which the second rail part or the rail plate is displaceable and fixable at a selected position. The first auxiliary rail thus supports the displaceable mounting and fastening of the rail plate and can, at least in the transition region between the first and second rail part at least partially limit the guide channel and form a tread or a tread part on which the guide member can be supported. If the first auxiliary rail is required for further purposes, for example for the storage of rollers of the drive, this may extend along the entire rail device and supplement the first rail part. If, for example, the first rail part has at least approximately an L-profile, this can be supplemented to form a U-profile on the basis of the first auxiliary rail preferably coupled thereto in a form-fitting manner. Through this synergistic connection can be dispensed with the formation of the first rail part with a complete U-profile.

For example, the first plate part of the rail plate is slidably and fixably connected to a wall profile of the first auxiliary rail, which adjoins the first side of the guide channel, which adjoins the first rail wall of the second rail part and which is coupled to a first profile part of the first rail part. Due to the wall element, which adjoins seamlessly to the first rail wall of the second rail part, a channel wall of the guide channel is therefore formed, at least in the transition region between the first and second rail part.

The second plate part of the rail plate is preferably slidably coupled to a second profile part of the first rail part and forms a wall piece of a second rail wall of the second rail part, which adjoins the guide channel together with a wall element of the second profile part of the first rail part and forms a common running surface for the guide element ,

The rail plate is preferably by means of screws with rail elements of the first rail part or with others Rail elements of the rail device, in particular the auxiliary rails connected. For this purpose, these rail elements preferably have a screw channel which runs parallel to the longitudinal axis of the first rail part and on the inside of which threaded elements are provided, in which mounting screws can engage in a form-fitting manner. The mounting screws can be mounted at any position of the screw channel extending along the rail device. The mounting plate can thus be moved continuously and fixed by means of mounting screws at any position.

The first plate part of the rail plate is e.g. connected by mounting screws with the coupling profile of the first auxiliary rail, which has a screw channel for receiving the mounting screws.

In contrast, the second plate part of the rail plate can have a coupling profile which engages positively in the second profile part of the first rail part.

In a preferred embodiment, a second auxiliary rail is provided, which is connected to the second or a third plate part of the rail plate. Preferably, the second rail also has a screw channel, in which mounting screws can be fixed at any points to connect the track plate stable on this page with the rail device.

In a preferred embodiment, the first and the second auxiliary rail, which are preferably interconnected by transverse struts, each have a running surface along which rollers of the drive are guided.

Fig. 1a shows a cabinet 9 according to the invention with a provided on the underside guide device 1, the two drives 11, 11 ', which are displaceably mounted in a rail device 2 according to the invention and which are each connected to a sliding door 91, 92. The sliding doors 91, 92 serve to lock each one cabinet opening and can be lifted from the associated cabinet opening and moved laterally. For stable leadership of Sliding doors 91, 92 are held and guided at the top by a respective complementary guide 6.

Fig. 1b shows the cabinet 9 of Fig. 1a after the first sliding door 91 has been lifted by means of the associated drive 11 from the cabinet opening 90 and laterally displaced parallel in front of the second sliding door 92. The complementary guide 6 at the top of the cabinet comprises in this preferred embodiment, a drive 62 which has been guided along a guide rail 68 to an intermediate wall 95 and which is connected via a curved guide lever 63 with the first sliding door 91.

Fig. 2a shows the cabinet 9 with the partially exposed guide device 1, which has a rail device according to the invention 2 and guided therein drives 11, 11 ', which are connected via drive arms 18, each with a guide fitting 19 (see Fig. 4b ). Shown further is the complementary guide 6 in the configuration of Fig. 1a after removing the first sliding door 91 and a side wall 94 and a section through the center of the cover plate 93rd

The drive 11 is displaceable within the rail device 2 along a guide rail such that the guide fitting 19 is displaced parallel to the complementary fitting 61 during the displacement of the sliding door 91. If necessary, the guide device 1 allows the sliding door 91 to be fully supported, after which the complementary guide 6 is not loaded by the weight force of the sliding door 91.

Fig. 2b shows the cabinet 9 in the configuration of Fig. 1b after removing the first sliding door 91 and a section through the center of the cover plate 93. The guide fitting 19 and Complementary fitting 61 has been displaced parallel to each other along identical curves k. The complementary drive 62 is located within the space opening 90 in the end stop near the partition wall 95, the complementary fitting 61 being held by the lever 63 in front of the second sliding door 92.

Fig. 3a shows the cabinet 9 in the configuration of Fig. 1b seen from below with the two drives 11, 11 ', which have been moved to the same side of the rail device 2. The second drive 11 'is in the closed position of the second sliding door 92 in the end stop, whereby the associated cabinet opening 90' is closed. The first drive 11 is in the open position of the first sliding door 91 in the end stop, whereby the associated cabinet opening 90 has been completely exposed.

In this preferred embodiment, the drive 11 has a first drive module 111, which is displaceable perpendicular to the cabinet front in relation to a second drive module 112, which can be moved parallel to the cabinet front. This will be with reference to the Fig. 4a and Fig. 4b explained in more detail below.

For the displacement of the first drive module 111, the rail device 2 has a rail channel 20 with a first channel section 201, to which a second channel section 202 connects on both sides, which runs along a curve against the rear side of the cabinet 9. Fig. 5d shows that in the rail channel 20, a guide roller 1111 is held, by means of which the first drive module 111 can be moved back and forth. The guide channel 20 is formed by a straight first rail part 21 and on both sides adjoining second rail parts 22, which are each part of a rail plate 220. The rail plate 220 is made of plastic or metal, for example. For example, the rail plate 220 manufactured by a die-casting or injection molding process, which allows to produce the curve shapes of the second rail parts 22 precisely.

The rail plate 220 with the second rail part 22 is displaceable relative to the first rail part 21, so that the rail channel 20 can, if necessary, be adapted to the dimensions of the cabinet 9 and the sliding door 91. Between the two rail parts 21, 22 thus results in a transition region 200 whose length changes in the displacement of the second rail part 22.

To move the drive 11 parallel to the cabinet front, the rail device 2 in addition to a first and a second auxiliary rail 31, 32, which are parallel to each other and straight. By means of the auxiliary rails 31, 32, the second drive module 112 of the drive 11 is mounted axially displaceable.

Despite the complexity of the rail device 2 this can be mounted together with the guide device 2 due to its flexibility and only then adjusted. An elaborate construction of the rail device on site is eliminated due to the adjustability of the rail device. 2

The guide device 1, as in Fig. 3a and Fig. 6 can be assembled and mounted on the cabinet cover or the bottom of the cabinet 96 and screwed. As a result, the second rail parts 22 can be moved as needed and then fixed. The assembly process is thus reduced to a few assembly steps and can be completed within a short time without special detailed knowledge.

Fig. 3b shows the cabinet 9 in the configuration of Fig. 3a seen from below without the drives 11, 11 'and the sliding doors 91, 92, with respect to the exposed rail device 2. It is shown that the rail device 2 is provided at both ends 2A, 2B with rail plates 220, which are arranged symmetrically to the cabinet center are. The now completely shown rail channel 20 has the shape of a wide "U" which can be stretched or compressed by displacement of the two rail plates 220 along the longitudinal axis x of the first rail part 21 in its width. The two rail plates 220 are now adjusted so that the two cabinet doors 91, 92, as in Fig. 1a shown, after closing close flush with the ends of the cabinet.

Fig. 4a shows a section through the rail device 2 along the in Fig. 3b Plotted line A - A with the first drive 11, which has a transverse to the cabinet front first drive module 111 and a movable parallel to the cabinet front second drive module 112 in which the first drive module 111 is slidably mounted. For clarity, some device parts are hidden, which are not required for the description of the invention. The section A - A passes through the first and second auxiliary rails 31, 32, in which the rollers 1121, 1122 of the second rail module 112 are mounted, and through the rail plate 220. The section passes through the part of the second channel section 202 of the second Rail part 22 which extends perpendicular to the cabinet front and in which the guide roller 1111 of the retracted first drive module 111 is in the end position.

Fig. 4b shows a section through the rail device 2 along the in Fig. 3b Plotted line B - B with the first drive 11 displaced up to this position and the first drive module 111 driven outwards transversely to the cabinet front, which is connected to the guide fitting 19 via the drive arms 18. The rail plate 220 has been cut away, so it can be seen that the guide roller 1111 is retracted into the first channel section 202 of the guide channel 20 and thus into the first rail part 21.

In this embodiment, the drive 11 has a tension spring 1123, which always exerts a tensile force F on the extended first drive module 111 and pulls it back against the second drive module 112. The guide roller 1111 is therefore drawn against a first rail wall of a profile part of the first rail part 21 and extends primarily along this rail wall.

Fig. 4b shows further that the two auxiliary rails 31, 32 on the bottom and the top each have a tread 315, 315 'and 325, 325'. When mounting the guide device 1 on the underside of the cabinet 9, the rollers 1121, 1122, as in Fig. 4b shown supported on the lower treads 315, 325. When mounting the guide device 1 at the top of the cabinet 9, the rollers 1121, 1122, however, on the opposite treads 315 ', 325' supported.

Fig. 5a shows a section through the rail device 2 along the in Fig. 3b drawn line C - C facing an end piece 2A of the rail device 2, on which the sliding rail plate 220 is provided.

Shown are the first rail part 21 and provided in the rail plate 220 second rail member 22, which are mutually displaceable and aligned with the facing end pieces coaxially with each other.

The FIGS. 5a and 5b show that the rail plate 220 is displaceable parallel to the longitudinal axis of the first rail part 21 and thus parallel to the cabinet front. For this purpose, the rail device 2 a plurality of bearing elements 218, 311, 2211; 219, 2191, 2221, which engage in one another in a form-fitting manner and by which the second rail part 22 is held displaceable parallel to a longitudinal axis x of the first rail part 21. Furthermore, fastening means 7, 317, 218 are provided, by means of which the second rail part 22 can be connected to the first rail part 21 at a selected position.

The connection of the second rail part 22 or the rail plate 220 with the first rail part 21 is for this preferred embodiment of the rail device 2 with reference to Fig. 5a and 5d explained.

In the present embodiment, the rail plate 220 has first, second, and third plate parts 221, 222, 223. The first plate part 221 is connected by a first auxiliary rail 31 to a first profile part 218 of the first rail part 21. The auxiliary rail 31 has a coupling profile 311 facing the first rail part 21, which comprises a screw channel 317, a receiving profile 3111 and a wall profile 3112. The first plate part 221 is screwed with mounting screws 7, which are inserted into the screw channel 317, with the first auxiliary rail 31 at a selected position. By a provided on the first plate member 221 coupling profile 2211 which engages in the receiving profile 3111 of the first auxiliary rail 31, there is an axial bearing of the rail plate 220th Das Wall profile 3112 adjoins the guide channel 20 and completes the approximately L-shaped first rail part 21 to a U-profile. The wall profile 3112 of the first auxiliary rail 31 also engages in a form-fitting manner in the first profile part 218 of the first rail part and in effect forms a rail wall for the guide channel 20.

This embodiment of the rail device 2 with the first auxiliary rail 31 is selected such that the auxiliary rail 31 is additionally used in the embodiment of the guide device 1 for the storage of a roller 1121 of the drive 11. The first auxiliary rail 31 and the form-fitting coupled first rail part 21 therefore complement each other ideally. Alternatively, however, it is also possible to use a U-profile-shaped first rail part 21 with a first profile part 218, which is connected to the rail plate 220 in the same way as the second profile part 219 of the first rail part 21. If necessary, the first rail part 21 is provided with its own screw channel. For example, Coupling profile 311 is taken from the first auxiliary rail and integrally connected to the first rail part 21.

The second profile part 219 of the first rail part 21 has a groove-shaped receiving profile 2191 into which a coupling part 2221 provided on the second plate part 222 engages, to which a wall piece 2222 adjoins. Fig. 5d shows that the second profile part 219 and the wall piece 2222 together form a running surface for the guide element 1111. The guide member 1111 is therefore further supported in the one or the other direction, either by the profile part 219 or by the wall piece 2222 in the onward journey or when leaving the transition region 200.

Fig. 5d further shows that the first rail part 21 and the first auxiliary rail 31 are screwed to a transverse strut 52 which results in a stable connection between the first rail part 21 and the first auxiliary rail 31.

The described connection of the first rail part 21 with the second rail part 22 forms the guide channel 20, which comprises the first channel section 201 along the first rail part 21 and the second channel section 202 along the second rail part 22, which meet in the transition region 200. The wall profile 3112 of the auxiliary rail 31 fits seamlessly into the first side wall 2201 of the second rail part 22. On the other hand, the wall piece 2222 of the second plate part 222 widens to the second side wall 2202 of the second rail part 22.

Fig. 5a further shows that the second plate part 222 of the rail plate 220 is followed by a third plate part 223, which is screwed to a second auxiliary rail 32. For this purpose, the second auxiliary rail 32 on a coupling profile 321, which is provided with a screw channel 327, are screwed into the mounting screws 7.

The first and the second auxiliary rail, which are interconnected by transverse struts 51, 52, have running surfaces 315, 325, along which runners 1121, 1122 of the second drive module 112 of the drive 11 are linearly guided. While the first drive module 111 of the drive 11 of Fig. 4a is guided with the guide roller 1111 along the curved guide channel 20, the second drive module 112 with the rollers 1121 and 1122 linearly along the two auxiliary rails 31, 32 are moved.

Fig. 5b shows the end piece 2A of the rail device 2 of Fig. 5a with the rail element 22 displaced outwards.

Fig. 5c shows the end piece 2A of the rail device 2 of Fig. 5a in exploded view.

Fig. 5d shows the end piece 2A of the rail device 2 of Fig. 5a in front view.

Fig. 6 shows a provided with the inventive rail device 2 guide device 1, which can be mounted on the underside or the top of a cabinet. The guiding device 1 can, as shown, be delivered fully assembled, mounted and subsequently adapted to the dimensions of the cabinet 9 by loosening the mounting screws 7 and displacing the mounting plates 220 as required, as shown in FIG Fig. 6 is shown.
