Description

[0001] The present invention relates to a device for moving a sliding door or folding-sliding door relative to a furniture wall with the features of the preamble of claim 1, a device for moving a movable furniture part, in particular a sliding door or folding-sliding door, relative to a fixed furniture part, in particular a furniture wall, with the features of the preamble of claim 18 and a piece of furniture with at least one such device.

[0002] Furthermore, the invention relates to a method for mounting a device on a furniture wall.

[0003] Devices for moving a sliding door or folding-sliding door relative to a furniture wall are already known, comprising a first guide system to be fastened to the furniture wall and a second guide system to be fastened to the furniture wall at a vertical distance from the first guide system. The two guide systems each have at least one guide and a guide body displaceably mounted on the guide, and a support to which the sliding door or folding-sliding door is to be fastened and which is connectable or connected in a movement-coupled manner to the two guide bodies of the guide systems. Such a device is disclosed, for example, in AT 519 374 B1. The disadvantage, however, is that the support can assume enormous dimensions depending on the dimensions of the respective piece of furniture. This not only complicates transport but also the assembly of such a support.

[0004] Based on this, a solution already exists that provides for the beam to be constructed in pieces. Such a pieced beam is described, for example, in AT 519 897 A1. However, such pieced beams require additional assembly steps, as the individual beam sections must be joined together before final assembly. Therefore, the assembly of such a pieced beam still involves considerable effort.

[0005] The document AT 519 513 A1 describes an arrangement for guiding a sliding door or folding-sliding door on a furniture wall, comprising a first guide system to be attached to the furniture wall and a second guide system to be attached to the furniture wall at a vertical distance from the first guide system. The two guide systems each comprise at least one guide and a guide body displaceably mounted on the guide, a support to which the sliding door or folding-sliding door is to be attached and which is motion-coupled to the two guide bodies of the guide systems, and a cable pull device for compensating a tilting moment of the support or the sliding door or folding-sliding door arranged thereon about a tilting axis by means of a restoring moment.The cable pulling device comprises at least two separate traction cables, wherein a first of these two traction cables is arranged between the guide body of the first guide system and at least one end of the guide of the first guide system and is designed to be seamlessly connected to the second guide system. A second of these two traction cables is arranged between the guide body of the second guide system and at least one end of the guide of the second guide system and is designed to be seamlessly connected to the first guide system.

[0006] Document US 8,231,187 B2 describes a hinge bracket that can be attached to a sliding door system. The sliding door system includes components capable of achieving a fully recessed or partially overlapping sliding door system position without the hinge bracket.

[0007] The object of the invention is to avoid at least one of the disadvantages described above and to provide a device, furniture and method that is improved compared to the prior art.

[0008] These objects are achieved by the features of independent claims 1, 13, 17 and 19.

[0009] Advantageous embodiments of the invention are defined in the dependent claims.

[0010] An essential idea with regard to the device according to the invention for moving a sliding door or folding-sliding door relative to a furniture wall, with a first guide system to be fastened to the furniture wall and a second guide system to be fastened to the furniture wall at a vertical distance from the first guide system, wherein the two guide systems each have at least one guide and a guide body displaceably mounted on the guide, and a carrier to which the sliding door or folding-sliding door is to be fastened and which is connectable or connected in a movement-coupled manner to the two guide bodies of the guide systems, is that the carrier comprises at least two carrier sections which are movable relative to one another in a longitudinal direction of the carrier, such that the length of the carrier can be adjusted by a relative movement of the at least two carrier sections to one another.In other words, the support is designed to be telescopic. This has the advantage that the support can now be very easily adapted to the specific dimensions of a piece of furniture. Furthermore, assembly is simplified, as joining individual support sections is no longer necessary. It should also be noted that, due to the connection to the guide bodies, which are slidably mounted on the guide, the support only moves with the guide bodies when the guide bodies move along the guide, but does not itself exert any rotational movement.

[0011] It can also be provided that the at least two carrier sections are frictionally connected to one another, preferably wherein at least one friction element is provided which is arranged on one of the at least two carrier sections and rests against the other of the at least two carrier sections, particularly preferably wherein the at least one friction element comprises a rubber material.

[0012] It is particularly advantageous if the at least two support sections are connected to one another purely by frictional engagement. Thus, the relative movement of the provided support sections is limited by the purely frictional connection of the support sections. In other words, no locking element is provided that acts directly on the support sections and locks them relative to one another.

[0013] Furthermore, it can be provided in a device that all pre-assembled components of the device have a maximum length of 1200 mm and a maximum width of 800 mm so that they can be arranged on a Europool pallet for shipping purposes.

[0014] On the other hand, an essential idea with regard to the device according to the invention for moving a movable furniture part, in particular a sliding door or folding-sliding door, relative to a fixed furniture part, in particular a furniture wall, with at least two spaced-apart engagement means, which are each rotatably mounted relative to a bearing device, and a telescopic synchronization device which connects the at least two engagement means to one another or via which the at least two engagement means can be connected to one another in order to synchronize a rotational movement of the at least two engagement means, is that at least one carrier is provided which is connected or connectable to at least one of the bearing devices of the at least two engagement means, surrounds the synchronization device at least in part and is telescopic.Because the carrier is connected or connectable to at least one of the bearing devices, the carrier does not perform any rotational movement when the engagement means rotate relative to the respective bearing device.

[0015] It can be provided that the respective bearing device of the at least two engagement means is arranged in or on one of the two guide bodies of the guide systems.

[0016] As mentioned above, protection is also sought for a piece of furniture with at least one furniture wall, at least one sliding door or folding-sliding door, and at least one device, wherein the first and second guide systems are attached to the at least one furniture wall and the at least one sliding door or folding-sliding door is attached to the support. The furniture can be provided with a receiving area for accommodating components of a kitchen, a clothes storage device, or the like.

[0017] Further advantages and details of the invention are apparent from the figures and the accompanying description. These show: Fig. 1 a perspective view of a piece of furniture with a folding sliding door and a device for moving the folding sliding door, Fig. 2 a perspective view of a device for moving a folding sliding door, Fig. 3a-3b perspective views of the first and second guide systems of the device, Fig. 4a-4d different representations of a carrier of the device, Fig. 5a-5d Detailed views of the carrier, Fig. 6a-6b a perspective view of the device and a detailed representation thereof, Fig. 7 a schematic representation of a furniture wall with a device for moving a folding sliding door in a partially assembled state, Fig. 8 a schematic representation of the furniture wall with the device in a further partially assembled state, and Fig. 9 a schematic representation of the furniture wall with the device in the assembled state.

[0018] Fig. 1 shows a piece of furniture 29 with a fixed furniture part 31 with two furniture walls 3 and a folding / sliding door 2, which comprises two door leaves 2a, although only one door leaf 2a is shown. This makes the receiving area 30 visible. The door leaves 2a can be pivotally connected to one another via the hinges 42. A device 1 for moving the folding / sliding door 2 relative to the furniture wall 3 is arranged on the right-hand furniture wall 3 in the illustration. At this point, it should be noted that such a device 1 can also be arranged on the opposite furniture wall 3, so that another folding / sliding door 2 could also be moved by this same device 1. In addition, another furniture wall can be provided parallel to the furniture wall 3, so that a receiving shaft is formed for receiving the folding / sliding door 2.

[0019] The device 1 comprises a first guide system 4 fastened to the furniture wall 3 and a second guide system 5 fastened to the furniture wall 3 at a vertical distance 6 from the first guide system 4, wherein the two guide systems 4, 5 each have at least one guide 7, 8 and a guide body 9, 10 displaceably mounted on the guide 7, 8. Furthermore, the device 1 comprises a support 11 to which the folding-sliding door 2 can be fastened. In this regard, the interfaces 20 are provided, to which the door leaf (not shown) of the folding-sliding door 2 can be fastened.It can thus be provided that the support 11 has at least two interfaces 20 for fastening the sliding door or folding-sliding door 2, preferably wherein the at least two interfaces 20 are arranged on different support sections 11a, 11b, 11c of the support 11, particularly preferably wherein at least one interface 20 is adjustable at least in the vertical direction 21, preferably also in the horizontal direction 22. The support 11 is further connected in a movement-coupled manner to the two guide bodies 9, 10 of the guide systems 4, 5. In addition, the support 11 comprises at least two support sections 11a, 11b, 11c, which are movable relative to one another in a longitudinal direction 12 of the support 11, so that the length 13 of the support 11 can be adjusted by a relative movement of the at least two support sections 11a, 11b, 11c to one another.

[0020] The piece of furniture 29 also has a carriage rail 33, along which a carriage 32 is slidably mounted. This carriage 32 is connected to the door leaf 2a via a hinge, so that by moving the carriage 32 along the carriage rail 33, the folding-sliding door 2 can be moved between a first position, in which the door leaves 2a are aligned substantially coplanar to one another, and a second position, in which the door leaves are aligned substantially parallel to one another. Also located in the extension of the carriage rail 33 is a transfer device 34, which is, however, connected to the guide body 9 and on which the carriage 32 can be arranged in the second position of the folding-sliding door 2. In this second position, the folding-sliding door 2 can then be moved along the guides 7, 8 of the two guide systems 4, 5, so that the folding-sliding door 2 can be lowered into a receiving shaft.

[0021] Fig. Figure 2 shows the device 1 with the carrier 11, which comprises the carrier sections 11a, 11b, 11c. It can be seen that the two guide bodies 9, 10 each have a locking device 26 for releasably securing the at least two carrier sections 11a, 11b, 11c to the corresponding guide body 9, 10. In the illustrated embodiment, the carrier sections 11b, 11c are releasably secured to the corresponding guide body 9, 10 via the respective locking device 26.

[0022] Fig. Figure 3a shows the first guide system 4 with the guide 7, along which the guide body 9 is slidably mounted. The pull cable 23a is visible, which is arranged between the two ends 7a, 7b of the guide 7 and whose function will be explained in more detail later.

[0023] Fig. Figure 3b, on the other hand, shows the second guide system 5 with the guide 8, along which the guide body 10 is slidably mounted. This shows the traction cable 23b, which is arranged between the two ends 8a, 8b of the guide 8 and whose function will also be explained in more detail later.

[0024] Fig. 4a shows the carrier 11 of the device 1, which comprises the three carrier sections 11a, 11b, 11c. Starting from the Fig. 4a, the support sections 11a, 11b, 11c can be moved relative to each other in the longitudinal direction 12 of the support 11, so that the length 13 of the support 11 is adjustable. Fig. 4b the carrier 11, wherein the carrier section 11b has been moved relative to the carrier sections 11a, 11c, so that the length 13 of the carrier 11 is now less than in Fig. 4a.

[0025] Fig. 4c shows an exploded view of the carrier 11, so that the synchronization device 15 is visible, which comprises the synchronization sections 15a, 15b, 15c, 15d. The synchronization sections 15a, 15b, 15c, 15d are movable relative to each other in the longitudinal direction 16, so that the length 17 of the synchronization device 17 is adjustable. Furthermore, the two synchronization sections 15c, 15d can be connected to the guide bodies 9, 10 by means of engagement means 24a, 24b (see Fig. 5a). It can therefore be provided that the device 1 comprises a synchronization device 15, via which the two guide bodies 9, 10 of the guide systems 4, 5 can be coupled to one another, preferably wherein the synchronization device 15 comprises at least two synchronization sections 15a, 15b, 15c, 15d, which are movable relative to one another in a longitudinal direction 16 of the synchronization device 15, so that the synchronization device 15 can be adjusted in its length 17 by a relative movement of the at least two synchronization sections 15a, 15b, 15c, 15d to one another.

[0026] As shown, at least one energy accumulator 18 can be provided to support the movement of a sliding door or folding-sliding door 2 relative to a furniture wall 3, preferably wherein the at least one energy accumulator 18 is arranged such that it is effective between one of the at least two synchronization sections 15a, 15b, 15c, 15d and one of the at least two support sections 11a, 11b, 11c and / or one of the two guide bodies 9, 10, particularly preferably wherein the at least one energy accumulator 18, preferably designed as a torsion spring, has two distal ends 18a, 18b, wherein a first end 18a is connected to one of the at least two synchronization sections 15a, 15b, 15c, 15d and a second end 18b is connected to one of the at least two support sections (11a, 11b, 11c) or one of the two guide bodies (9, 10) is connected.Also visible are the two sleeves 28a, 28b, via which the two synchronization sections 15a, 15c can be connected to each other and the two synchronization sections 15b, 15d can be connected to each other. The intermediate pieces 25a, 25b, 25c, however, are connected to the respective support section 11a, 11b, 11c and serve to rotatably support the synchronization device 15. However, the synchronization device 15 is connected to the intermediate pieces 25a, 25c in such a way that a movement of the support sections 11a, 11b, 11c relative to each other simultaneously moves the synchronization sections 15a, 15b, 15c, 15d relative to each other.It can thus be provided that a first 15a of the at least two synchronization sections 15a, 15b, 15c, 15d is connectable or connected to a first 11c of the at least two carrier sections 11a, 11b, 11c and a second 15b of the at least two synchronization sections 15a, 15b, 15c, 15d is connectable or connected to a second 11b of the at least two carrier sections 11a, 11b, 11c, so that by a relative movement of the at least two carrier sections 11a, 11b, 11c to one another, the carrier 11 can be adjusted in its length 13 and at the same time also the synchronization device 15 can be adjusted in its length 17, and / or wherein the synchronization device 15 is arranged substantially in the interior of the carrier 11. The plug pins 41 also serve to connect the respective synchronization sections 15a, 15c and 15b, 15d to each other.Finally, the recesses 35 in the support sections 11b, 11c are visible, which serve to connect the support sections 11b, 11c with the respective guide body 9, 10 (see . Fig. 6a).

[0027] Fig. 4d shows a top view of the carrier 11. The friction elements 14 are visible, which are connected to the carrier section 11b and bear against the carrier section 11a. It can therefore be provided that the at least two carrier sections 11a, 11b, 11c are connected to one another in a frictionally engaged manner, preferably with at least one friction element 14 being provided, which is arranged on one of the at least two carrier sections 11a, 11b, 11c and bears against the other of the at least two carrier sections 11a, 11b, 11c, particularly preferably with the at least one friction element 14 comprising a rubber material. It is preferably provided that the at least two carrier sections 11a, 11b, 11c are connected to one another purely in a frictionally engaged manner.

[0028] In addition, the socket pin 41 and the locking device 19 are visible, wherein the locking device 19, in the assembled state of the device 1, protrudes through the synchronization sections 15a, 15c, through the sleeve 28a and through the energy accumulator 18. It can thus be provided that the at least one energy accumulator 18 is designed as a torsion spring, wherein the torsion spring is preloaded in the delivery state and is secured by a locking device 19, preferably a grub screw, wherein the preload is released by loosening the locking device 19, so that a driving force can be exerted by the torsion spring on the synchronization device 15 and thus on a sliding door or folding-sliding door 2.

[0029] Fig. Figure 5a shows the guide body 9, on which the carriage 32 is arranged. This carriage 32 comprises the rolling elements 36a, 36b, wherein the rolling elements 36a serve to absorb horizontal forces and the rolling element 36b serves to absorb vertical forces. Furthermore, the bearing device 27 is shown, which serves to rotatably support the engagement means 24a of the guide body 9. The traction cable 23a can be wound and unwound on the engagement means 24a during a movement of the guide body 9 along the guide 7 of the first guide system 7a. Also shown is the locking device 26, which has an eccentric lever 38 and two opposing plates 39a, 39b, wherein the plates 39a, 39b are connected to one another and to the eccentric lever 38 via a bolt 40 (see also Fig. 5d). The guide body 10 is also designed similarly. It can therefore be provided that the respective bearing device 27 of the at least two engagement means 24a, 24b is arranged in or on one of the two guide bodies 9, 10 of the guide systems 4, 5. The synchronization sections 15c, 15d furthermore have a flattened area, so that by connecting the synchronization sections 15c, 15d to the engagement means 24a, 24b, a movement coupling can be established between the engagement means 24a, 24b and the synchronization sections 15c, 15d, and thus the synchronization device 15.

[0030] Fig. 5b shows a sectional view of the Fig. 5a, wherein the eccentric lever 38 and thus also the plates 39a, 39b were rotated counterclockwise and the eccentric lever 38 itself was actuated. This reveals the opening 37 through which the locking device 19 is accessible. By unscrewing the locking device 19, designed as a grub screw, the force stored in the energy accumulator 18 can be released. Also shown here are the plug pin 41 and the associated connection to the support sections 15a, 15c and the sleeve 28a. Furthermore, the locking device 19 has already been partially unscrewed.

[0031] Fig. Figure 5c shows another sectional view of the Fig. 5a, wherein the locking device 19 starting from the Fig. 5b has been unscrewed sufficiently far so that the locking device 19 no longer prevents a rotational movement of the synchronization device 15 relative to the carrier 11 and thus a discharge of the energy accumulator 18 is possible.

[0032] Fig. 5d shows a sectional view of the Fig. 5a, so that the bolt 40, via which the eccentric lever 38 is connected to the plate 39b, is visible. The other plate 39a is also connected to the bolt 40, but this plate 39a is mounted displaceably along the bolt 40, so that by actuating the eccentric lever 38, the plates 39a, 39b are movable relative to each other.

[0033] Fig. 6a shows the carrier 11, which is not yet connected to the two guide bodies 9, 10. Fig. Figure 6b shows a detailed view of the framed area of ​​the Fig. 6a. The recess 35 of the support section 11c is visible. To connect the support section 11c to the guide body 9, the support section 11c is screwed onto the bolt 40 (see Fig. 5d) such that the bolt 40 can be moved into the recess 35. After the bolt 40 has been moved into the recess 35, the carrier 11 is moved such that the bolt strikes the left end of the recess 35 in the illustration. The locking device 26 is then locked, so that the carrier section 11c is firmly connected to the guide body 9. A similar process is carried out when connecting the carrier section 11b to the guide body 10. However, when the relevant bolt 40 is moved into the recess 35 of the carrier section 11b, a relative movement of the carrier sections 11a, 11b, 11c to one another is carried out, so that the length 13 of the carrier 11 is essentially adapted to the vertical distance 6 between the two guide systems 4, 5 in the usual assembly position.It can therefore be provided that the two guide bodies 9, 10 each have a locking device 26 for the releasable fastening of the at least two carrier sections 11a, 11b, 11c to the corresponding guide body 9, 10.

[0034] Fig. 7, Fig. 8 and Fig. 9 each show a schematic representation of a furniture wall 3 and a device 1 for moving a folding-sliding door 2 relative to the furniture wall 3 in different mounting positions. The cable pull device 23, which comprises the two pull cables 23a, 23b, is visible.It can therefore be provided that the device 1 has a cable pulling device 23 for compensating a tilting moment KM of the support 11 and a sliding door or folding-sliding door 2 arranged thereon about a tilting axis KA by means of a restoring moment RM, preferably wherein the cable pulling device 23 comprises at least two separate pulling cables 23a, 23b, a first 23a of these two pulling cables 23a, 23b is arranged between the guide body 9 of the first guide system 4 and at least one end 7a, 7b of the guide 7 of the first guide system 4 and is designed without a connection to the second guide system 5, and a second 23b of these two pulling cables 23a, 23b is arranged between the guide body 10 of the second guide system 5 and at least one end 8a, 8b of the guide 8 of the second guide system 5 and is designed without a connection to the first guide system 4.

[0035] Furthermore, as is the case in the present exemplary embodiment, it can be provided that each of the guide bodies 9, 10 comprises at least one engagement means 24a, 24b for at least one traction cable 23a, 23b, and the engagement means 24a, 24b of the guide bodies 9, 10 can be coupled to one another via a synchronization device 15, which is preferably separate from the carrier 11, preferably wherein the synchronization device 15 is designed to transmit a torque between the engagement means 24a, 24b of the guide bodies 9, 10.

[0036] The carrier 11 comprises two carrier sections 11a, 11b, which are movable relative to one another in the longitudinal direction 12 of the carrier 11, such that the length 13 of the carrier 11 can be adjusted by a relative movement of the carrier sections 11a, 11b to one another. In the usual assembly position of the device 1, the longitudinal direction 12 runs essentially parallel to the vertical direction 21 and essentially normal to the horizontal direction 22. Furthermore, the carrier 11 comprises a synchronization device 15, which has two synchronization sections 15a, 15b, which are movable relative to one another in a longitudinal direction 16 of the synchronization device 15, such that the length 17 of the synchronization device 15 can be adjusted by a relative movement of the synchronization sections 15a, 15b to one another.The longitudinal direction 16 of the synchronization device 15 also runs, in the usual assembly position of the device 1, essentially parallel to the vertical direction 21 and essentially normal to the horizontal direction 22. Furthermore, the support 11 has a force accumulator 18, which acts between the synchronization section 15a and the support section 11a, and wherein a force stored in the force accumulator 18 is secured by a locking device 19. Furthermore, the interfaces 20 are provided, at which the folding-sliding door 2 can be arranged. Furthermore, the guide bodies 9, 10 each have a locking device 26 for releasably fastening the support sections 11a, 11b to the corresponding guide body 9, 10. In . Fig. 7, the locking device 26 of the guide body 9 is shown in the closed position and the locking device 26 of the guide body 10 is shown in the open position.

[0037] In the following, the method according to the invention for mounting a device 1 on a furniture wall 3 will be described with reference to the sequence of figures of Fig. 7 to 9, where - in a first process step, the first guide system 4 or the second guide system 5 is attached to the furniture wall 3 (see Fig. 7), - in a second process step, the other guide system 4, 5 is fastened to the furniture wall 3 at a vertical distance 6 from the guide system 4, 5 fastened to the furniture wall 3 during the first process step (see Fig. 7), - in a third method step, one 11b of the at least two carrier sections 11a, 11b is connected to one 10 of the two guide bodies 9, 10 (see Fig. 8), - in a fourth process step, the length 13 of the carrier 11 is essentially adapted to the vertical distance 6 of the two guide systems 4, 5 (see Fig. 9), and - in a fifth method step, the other 11a of the at least two support sections 11a, 11b is connected to the other guide body 9, so that the guide bodies 9, 10 of the guide systems 4, 5 are connected to one another in a movement-coupled manner via the support 11.

[0038] It may be provided that after the fifth process step, the following process step is additionally carried out: - Loosening a locking device 19, preferably a grub screw, by means of which a force stored in a force accumulator 18 can be locked, so that a driving force is exerted on a sliding door or folding sliding door 2 (see Fig. 9).

[0039] In the present case, the locking device 19 in the form of a grub screw was turned out so far that the locking device 19 is only connected to the carrier section 11a, but no longer simultaneously to the synchronization section 15a and the energy accumulator 18.

[0040] Furthermore, the at least two carrier sections 11a, 11b can be suspended from the respective guide body 9, 10 during the third and / or fifth method step and / or each locked via a locking device 26.

[0041] Finally, it is possible that in the course of the adaptation of the length 13 of the carrier 11 carried out in the fourth method step, essentially to the vertical distance 6 between the two guide systems 4, 5, preferably simultaneously, a length 17 of a synchronization device 15 is essentially adapted to the vertical distance 6 between the two guide systems 4, 5, preferably wherein in the course of the adaptation of the length 17 of the synchronization device 15, a first synchronization section 15a of the synchronization device 15 is connected to an engagement means 24a of the first guide body 9 and a second synchronization section 15b of the synchronization device 15 is connected to an engagement means 24b of the second guide body 10, so that the two engagement means 24a, 24b are coupled to one another.

[0042] At this point, it should be noted that by coupling the support sections 11a, 11b to the guide bodies 9, 10 of the guide systems 4, 5, the support sections 11a, 11b are fixed relative to one another. Although the preferably provided friction elements 14 ensure a frictional connection between the support sections 11a, 11b, relative movement of the support sections 11a, 11b to one another is still possible.
