Description

[0001] The present invention relates to a fitting for a sliding door, in particular of a piece of furniture or household appliance or a partition, with a rail having at least one track along which a running part with at least one roller can be moved, wherein the running part has a holder made of a metal sheet and an adapter, wherein at least one retaining means is provided on the adapter to fix at least one further functional part to the adapter.

[0002] German patent DE 10 2011 050 395 A1 discloses a fitting for a sliding door in which the sliding doors are held on the tracks by means of running elements. Each running element comprises a rotatably mounted roller and an anti-derailment device fixed longitudinally to a mounting plate of the running element along the track. The anti-derailment device has a pivotally mounted lever that is fixed to a holder. An activator is also provided, which can be coupled to a self-closing mechanism. A problem with such running elements is that the various additional functions of the running element usually require separate attachment to the metal sheet of the running element. This necessitates numerous components and fasteners. Furthermore, assembly is complex, as all functional parts must be individually positioned and attached to the metal sheet.

[0003] EP 2 330 268 A2 discloses a sliding door with a running element that can be braked in an end position by means of a damper. For this purpose, the running element is coupled to a driver that moves along a guide track.

[0004] In WO 2012 / 156340 A1, a fitting for a sliding door is disclosed in which at least one roller is rotatably mounted on a holder, the holder being slidably mounted relative to a mounting plate that can be fixed to a sliding door. An adjustment mechanism allows the vertical position of the mounting plate to be aligned relative to the holder so that an activator is positioned for self-closing and / or a stop.

[0005] DE 20 2009 014 882 U1 discloses a fitting set for two sliding door leaves with running parts for a rear and a front sliding door leaf, wherein each running part has a roller carrier attached to the sliding door leaf and an activator for actuating a closing aid.

[0006] Further fittings for sliding doors are shown in documents DE 20 2013 104 004 U1 and DE 10 2009 052 419 A1.

[0007] It is therefore an object of the present invention to create a fitting for a sliding door that allows for increased flexibility in the assembly of functional parts.

[0008] This problem is solved with a fitting for a sliding door having the features of claim 1.

[0009] In the fitting according to the invention, the running element includes a holder made of a metal sheet and an adapter to which an anti-disengagement device is attached. Additionally, at least one retaining element is formed on the adapter to fix another functional part to it, so that, depending on the design of the fitting, the functional parts can be fixed to the adapter. The functional parts can be mounted to the adapter without tools; they simply need to be inserted, slid, or otherwise attached to the adapter. During the assembly of the furniture, it can then be decided which function the fitting part should perform, with the corresponding functional part simply being mounted on the adapter.

[0010] Preferably, the adapter is provided with at least two retaining elements, and in particular at least three retaining elements, to fix two or three different functional parts to the adapter. The retaining elements can be designed as a groove, recess, hook, and / or opening, depending on which connection mechanism is suitable for the functional part. The functional parts can then be fixed to the adapter by clamping and / or snapping.

[0011] In a further embodiment of the invention, at least one activator for coupling the running element with a self-closing mechanism for an opening or closing movement is provided or integrally formed on the adapter. The self-closing mechanism can provide movement of the sliding door in either the opening or closing direction, depending on the position in which the self-closing mechanism is mounted. The self-closing mechanism can be designed with damping so that the sliding door is slowed down before reaching an end position.

[0012] Alternatively or additionally, at least one stop can be mounted on the adapter to act as a spacer against a track of an adjacent sliding door. This allows the sliding door to be moved to a maximum end position relative to an adjacent sliding door during an opening movement.

[0013] For easy assembly of the functional components, the adapter can have an undercut groove on the top or another side into which the functional components can be inserted. This simplifies assembly and also allows for the arrangement of several functional components side by side.

[0014] In a further embodiment, a locking device for locking the sliding door in an end position can be mounted on the adapter.

[0015] To accommodate the individual mounting points and retaining elements on the adapter, it is preferably made of plastic, particularly by injection molding. The adapter can be fixed to the metal plate of the track using screws, which simultaneously also serve to fix the track to a sliding door, thus securing both the adapter to the bracket and the track to the sliding door. Preferably, the adapter is designed such that the openings for the screw heads are extended to allow the use of identical screws of the same length. This prevents incorrectly selected screws from damaging the surfaces of sliding doors or reducing the minimum load-bearing capacity in the sliding door / track area. Furthermore, standardized fastening materials can be used, which significantly simplifies inventory management and assembly.

[0016] According to the invention, means are provided to attach and pre-fix the adapter to the holder, which simplifies assembly.

[0017] The fitting according to the invention preferably has two running parts, one for the front sliding door and one for the rear sliding door, with an adapter for mounting functional parts being provided on both running parts.

[0018] The invention is explained in more detail below with reference to several exemplary embodiments and the accompanying drawings. These show: Fig. 1 a perspective view of a piece of furniture with a fitting according to the invention; Fig. 2 a perspective view of a fitting for the front door; Fig. 3 a perspective view of a fitting on the rear door; Fig. 4 a perspective view of the running part for the rear door; Fig. 5A to 5E several views of the running part of the Fig. 4 in different configurations; Fig. 6 a perspective view of the adapter of the running part of the Fig. 4; Fig. 7A and Fig. 7B Two views of two running parts with a spacer in different positions; Fig. 8 a perspective view of an activator on the running part in the engagement position; Fig. 9A to 9C several views of a fitting of a front sliding door; Fig. 10 a perspective view of the adapter of the fitting of the Fig. 9; Fig. 11A and Fig. 11B two views of two running parts of the fittings with a stop, and Fig. 12A to 12E several views of a running part for a rear sliding door.

[0019] A cabinet unit 1 comprises a cabinet body 2, to the top of which a rail 3 is fixed. In the lower area, another rail can be provided on one of the bases of the cabinet body 2 to guide a rear sliding door 4 and a front sliding door 5.

[0020] In Fig. Figure 2 shows a running element 40 of the fitting, which suspends the front sliding door 5 from the track 3. The track 3 has an upper raceway 6 in which a roller of the running element 40 is movably mounted. An activator 49 is provided on the running element 40, which engages with a driver 8 of a self-closing mechanism, the housing 7 of which is mounted on the underside of the top panel. The driver 8 engages through a recess in the track 3.

[0021] In Fig. Figure 3 shows a running element 10 for the movable support of the rear sliding door 4. The running element 10 comprises a roller that is movable in a lower track 6' of the rail 3, the tracks 6 and 6' being arranged vertically one above the other. A projection 29, acting as an activator, is provided on the running element 10 and engages with a follower 8 of a self-closing mechanism. The housing 7 of the self-closing mechanism is mounted on the underside of the top panel, and the follower 8 of the self-closing mechanism for the rear sliding door 4 also passes through a recess in the rail 3. Self-closing mechanisms can be provided distributed across the furniture body 2 in both the closed and, if required, the open positions of the sliding doors 4 and 5.

[0022] In Fig. Figure 4 shows the running element 10 in detail. The running element 10 comprises a holder 11 made of sheet metal, in which several openings 12 are cut out so that the holder 11 can be fixed to the rear sliding door 4 using screws. An adapter 14 is fixed to the holder 11, which has an opening 12' that aligns with an opening 12 in the holder 11, so that both the adapter 14 and both parts together can be fixed to the sliding door 4 using a single screw. A roller 13 is rotatably mounted on the adapter 14 and rolls on the track 6' of the rail 3. Two or more running elements 10 can be mounted on the sliding door 4.

[0023] The adapter 14 is manufactured as a molded plastic part and has numerous retaining elements to secure functional components. First, bearing ribs 15 are arranged on opposite sides of the roller 13, on which an anti-dislodgement device is rotatably mounted. The anti-dislodgement device comprises a bearing element 16, which is rotatably held on the bearing ribs 15, and a lower rib 17, which engages the rail 3 below the track 6' in the locked position. The two ribs 17 are connected to each other via a handle section 18, which is located below the roller 13. By pivoting the handle section 18 towards the holder 11, the locked position can be released to allow the sliding door 4 to be lifted for removal. During assembly, after the sliding door has been hung, the handle section 18 is pivoted so that a rib of the rail 3 with the track 6' is received in a receptacle 19 between the bearing element 16 and the lower rib 17.

[0024] The adapter 14 also has an undercut groove 20 on its upper surface, to which several functional parts are mounted and inserted. The functional parts can be mounted on the adapter 14 as needed; that is, only some or none of the functional parts can be fixed to the adapter 14.

[0025] A first functional part is designed as a retaining element 21, which is fixed in the groove 20 by a base section 22. Two parallel oriented webs 23 are formed on the base section 22; these webs are designed to be flexible and have a tapered neck section, so that the webs 23 can be locked onto a component, in particular to detachably fix the sliding door 4 in an open or closed position.

[0026] Another functional component is a spacer 24, which is also secured by being inserted into the groove 20. The spacer 24 has a protruding projection 25, which serves as a stop against another component, in particular an adjacent sliding door.

[0027] Furthermore, an activator 26 is fixed to the groove 20, which protrudes obliquely upwards from the top of the adapter 14 and has an angled projection 27 which can engage with a driver of a self-closing mechanism to enable opening damping.

[0028] Furthermore, the adapter 14 has two projections 29 molded onto opposite sides of the roller 13, which can also be used as activators to engage the running element 10 in an open or closed position with a self-closing mechanism. It is also conceivable to insert or slide these activators 29 as separate components into corresponding retaining elements formed on the adapter 14.

[0029] A collision damper 30 is provided on one side of the adapter 14 and is inserted into an opening 28 on the adapter 14. The collision damper 30 has an outer stop 31 and can be compressed to exert a damping force.

[0030] In Fig. In section 5A, the adapter 14 is fixed to the holder 11, with a locking device rotatably fixed to the bearing lugs 15 in addition to the activators 29. No other functional parts are provided on the adapter 14.

[0031] In Fig. 5B was compared to Fig. 5A The spacer 24 is inserted into the groove 20 to use it as a stop against an adjacent sliding door.

[0032] In Fig. In 5C, the spacer 24 on the adapter 14 was further supplemented by the activator 26.

[0033] In Fig. Figure 5D shows a design on adapter 14 in which only a retaining element 21 for a locking mechanism is inserted into the groove 20 to latch the sliding door in an open or closed position. Furthermore, a collision damper 30 is inserted into the opening 28 of adapter 14.

[0034] In Fig. Figure 5E shows a configuration in which a collision damper 30, the retaining element 21, and the activator 26 are mounted on the adapter 14. The mounting of the functional parts can be freely configured depending on the application.

[0035] In Fig. Figure 6 shows the adapter 14 without functional parts, and it can be seen that a variety of functional parts can optionally be attached to the adapter 14, depending on the design of the fitting.

[0036] In the Fig. 7A and Fig. Figure 7B illustrates the function of the spacer 24. The spacer 24 is mounted on the running element 10 via the adapter 14 and serves to maintain a predetermined distance between the sliding door 4 and an adjacent sliding door 5. For this purpose, the spacer 24 projects upwards from the adapter 14, and a projection 25 can engage with a stop 39 located adjacent to a roller 13 of the running element 40. The stop 39 can be formed on the holder 11, 41 or on the adapter 14, 44 of the running element of the other sliding door 4, 5.

[0037] In Fig. Figure 8 shows the function of the activator 26, which is fixed to the upper groove 20 of the adapter 14. The activator 26 engages with its projection 27 in a receptacle of a driver 33, which is movably mounted on a housing 32. The driver 33 is held in an open or closed position by a spring, and a damper can optionally be provided to slow the movement of the driver 33 and thus of the sliding door 4.

[0038] In the Fig. Figures 9A to 9C show an embodiment of a running element 40 of a front sliding door 5. The sliding door 5 can be suspended from two or more running elements 40. The running element 40 comprises a bracket 41 made of a sheet metal part, which is designed as an angle and has a horizontal upper section 42. The vertical section is provided with openings 43 for fixing the bracket 41 to the sliding door 5 by means of screws. An adapter 44 is fixed to the upper horizontal section 42 to allow functional parts to be mounted on the running element 40.

[0039] The adapter 44 includes U-shaped guide ribs 45 on opposite sides, into which a lateral edge section 46 of the horizontal section 42 is inserted. This allows the adapter 44 to be pre-fixed, and after assembly, it can be secured to the section 42 by means of screws 57.

[0040] Adapter 44 is equipped with an anti-lift device which is pivotably mounted on the adapter 44. The anti-lift device comprises a horizontal web 50 which engages the profile of the rail 3 below the track 6 to prevent the sliding door 5 from being lifted. The web 50 is connected to a handle section 51 to allow the anti-lift device to be pivoted from a locked position to a released position.

[0041] In Fig. 9B shows the adapter 44 with a first functional part in the form of an activator 49 for closing damping. The activator 49 is also shown in Fig. Figure 2 shows how it engages with a driver 8 of a self-retracting mechanism. Furthermore, a stop 56 is formed adjacent to the activator 49, which acts as an impact surface for a collision damper 30.

[0042] In Fig. In 9C, the running element 40 is additionally provided with an activator 47, which can engage with a self-closing mechanism for opening damping. For this purpose, the activator 47 has a ridge 48, which can engage with a driver of a self-closing mechanism for opening damping.

[0043] In Fig. Figure 10 shows the adapter 44 without functional parts. It can be seen that the adapter 44 has a central opening 53 for mounting the rotatable roller 13, with bearing elements 52 for securing it against dislodging being provided on opposite sides of the roller. The through-holes 54 for the screws 57 are also shown.

[0044] On opposite sides, the adapter 44 has an undercut groove 55 for mounting the activators 47 and / or 49.

[0045] In the Fig. 11A and Fig. Figure 11B shows the function of the stop 56, which can be engaged with the collision damper 30 of the running element 10. When the sliding doors 4 and 5 are moved one above the other, the stop 31 of the collision damper 30 first comes into contact with the stop 56. This slows the movement of the rear sliding door 4 relative to the front sliding door 5, regardless of whether the front sliding door 5 or the rear sliding door 4 is being moved. In any case, a loud impact is avoided by first moving the collision damper 30 against the stop 56.

[0046] In the Fig.Figures 12A to 12E show a running element 10 for a rear sliding door 4, on which an adapter 14 is arranged. The openings 12' have such lengths and diameters that the same screws 57 can be used to fasten the adapter 14 to the holder 11 or to the sliding door 4 as are used to fasten the holder 11 to the sliding door 4 via the openings 12 formed on the holder 11.

[0047] In the illustrated embodiments, adapters 14 and 44 are equipped with several functional parts, which in particular form a self-closing mechanism, a damping mechanism, a spacer, or a stop. It is, of course, possible to attach further functional parts to adapters 14 and 44. Furthermore, when assembling the fitting, the user can decide which of the aforementioned functional parts are mounted on adapters 14 and 44, with the functional parts preferably being able to be mounted without tools, so that the fitting can be assembled appropriately, similar to a modular system.
