[0002] Furthermore, the invention relates to a piece of furniture with at least one movable furniture part, in particular at least one furniture door, a fixed furniture part and at least one such arrangement.

[0003] Arrangements for guiding a movable furniture part relative to a stationary furniture part are known from the prior art.

[0004] The applicant's own WO 2018 / 129568 A1 discloses an arrangement for guiding a movable furniture part, in particular at least one furniture door, relative to a stationary furniture part, wherein in one embodiment two such arrangements for guiding a movable furniture part are provided, which make it possible to move a movable furniture part along a guide rail arranged on a stationary furniture part. A similar arrangement is disclosed in US 5078461A.

[0005] If the movable furniture part comes to an abrupt stop during a movement – ​​for example, due to it hitting an obstacle – the at least one first ropes of the two arrangements are subjected to a high load at a connection point between the at least one first ropes and the stationary furniture part. This constitutes an overload situation. Such an overload can lead to the breaking of the at least one first ropes or to the loosening of a connection between the at least one first ropes and the stationary furniture part.

[0006] The object of the present invention is to overcome the disadvantages of the prior art and to provide a fastening device that is improved compared to the prior art. A further object is to provide a piece of furniture with at least one such arrangement.

[0007] These problems are solved by the features of independent claims 1 and 9.

[0008] With regard to the arrangement, it is therefore provided that the at least one fastening device has a bearing device which is designed in such a way that the at least one first rope is mounted so as to be movable to a limited extent in an overload case relative to the stationary part of the furniture.

[0009] This ensures that at least one of the first cables does not break in an overload situation, or that the connection between the at least one first cable and the stationary furniture part does not come loose. Instead, any overload that occurs is compensated for by the relative movement of the at least one first cable relative to the stationary furniture part.

[0010] It is also provided that the storage device comprises at least one slide to which the at least one first rope can be attached. Furthermore, it is provided that the storage device comprises at least one device for fixing the at least one first rope, wherein preferably the at least one fixing device comprises a notch.

[0011] According to the invention, the at least one fastening device has at least one guide for guiding the at least one slide.

[0012] This makes it easier to carry out a limited movement of at least one first rope, at least in an overload case, relative to the stationary part of the furniture.

[0013] It is further provided that the at least one fastening device includes at least one elastic means for absorbing forces acting on the at least one first rope.

[0014] This allows for better compensation of the overload. Furthermore, the presence of at least one elastic element ensures a dampened deceleration of the movable furniture part into its end position.

[0015] Furthermore, the arrangement comprises at least one additional guide rail, at least one additional guide device movably mounted thereon, at least one additional cable which can be attached to the stationary furniture part on one side and coupled to the at least one additional guide device on the other, and at least one additional fastening device for attaching the at least one additional cable to the stationary furniture part, wherein the at least one additional fastening device includes a bearing device designed such that the at least one additional cable is mounted with limited movement relative to the stationary furniture part, at least in the event of an overload. This results in improved support of the movable furniture part on the stationary furniture part.

[0016] Finally, at least one support is provided to which the movable furniture part can be attached, and which is movably mounted on the provided guide rails via the provided guide devices.

[0017] Further advantageous embodiments of the invention are defined in the dependent claims.

[0018] It has also proven advantageous that the at least one fastening device comprises at least one base body, wherein the at least one elastic means is connected to the at least one base body and the bearing device.

[0019] This creates suitable points of attack for at least one elastic means.

[0020] According to another aspect of the invention, the at least one elastic means is designed as a spring, preferably as a compression spring.

[0021] It may also be provided that at least one first rope is arranged partially inside the spring.

[0022] This facilitates a space-saving design of the arrangement.

[0023] It can also be provided that at least one guide for guiding at least one slide is designed in a groove shape.

[0024] Preferably, the at least one fastening device may include an interface for connecting the at least one fastening device to the stationary furniture part and / or to the at least one guide rail, preferably at one end of the at least one guide rail.

[0025] According to a further aspect of the invention, the first rope and the at least one further rope can each be attached in the region of one end of the respective guide rail to the stationary part of the furniture, wherein the ends of the respective guide rail are spaced apart from each other in a longitudinal direction of the guide rails.

[0026] This distributes the overload occurring in an overload situation between the two arrangements, thus reducing the individual load on each arrangement.

[0027] It may also be provided that the arrangement includes at least one synchronization device for synchronizing the movements of the provided guide devices.

[0028] This prevents the guide devices from jamming due to uneven stress on the movable part of the furniture.

[0029] Preferably, the furniture may include at least one, preferably shaft-shaped, cavity for at least partially accommodating the at least one movable furniture part.

[0030] Further details and advantages of the invention are explained in more detail below with reference to the figures and the drawings. These show: Fig. 1 a perspective front view of a piece of furniture with an arrangement according to the invention, Fig. 2a a schematic representation of an arrangement according to the invention with a movable and a stationary furniture part, Fig. 2b a schematic representation of an arrangement according to the invention with a movable and a stationary furniture part in an overload case, Fig. 3 a schematic representation of a further embodiment of an arrangement according to the invention with a movable and a stationary furniture part, Fig. 4 a schematic representation of a further embodiment of an arrangement according to the invention with a movable and a stationary furniture part, Fig. 5 a perspective view of an arrangement according to the invention, Fig. 6 an arrangement according to the invention in a perspective exploded view, Fig. 7 a side view of an arrangement according to the invention, Fig. 8 a side view of an arrangement according to the invention in an overload case

[0031] Figure 1 Figure 1 shows a perspective front-side view of a piece of furniture 100. This piece of furniture 100 has two movable furniture parts 2, each comprising two furniture fronts 24. Also visible are a stationary furniture part 3 designed as a furniture body and cavities 101 arranged on this stationary furniture part 3 for receiving the movable furniture parts 2. The movable furniture parts 2 can be folded together by means of the carriages 25 and the rail system 26, and can also be moved, at least partially, into the cavity 101 by means of the arrangements 1 according to the invention (not visible).

[0032] Figure 2a Figure 1 shows an embodiment of the invention comprising two arrangements 1 according to the invention, a movable 2 and a fixed furniture part 3 in a schematic side view.

[0033] The ropes 6, 19 of the arrangements 1 are on the one hand coupled to the guide devices 5, 18 by means of coupling devices 27 and on the other hand attached to the fixed furniture part 3 by means of the fastening devices 7, 20 via the guide rails 4, 17.

[0034] A fastening device 7, 20 is arranged at one end 16 of the guide rail 4 and a second fastening device 7, 20 is arranged at one end 21 of the guide rail 17. No fastening device is arranged at the ends 160, 210 of the guide rails 4, 17.

[0035] Furthermore, a synchronization device 23 is visible, which synchronizes the movements of the guide devices 5, 18.

[0036] The longitudinal direction L of the guide rails 4, 17 is also recognizable.

[0037] Figure 2bFigure 1 shows an embodiment of the invention comprising two arrangements 1 according to the invention, a movable 2 and a stationary furniture part 3 in a schematic side view in an overload case.

[0038] An obstacle 28 is visible, onto which the movable furniture part 2 has collided. As a result, the movable furniture part 2, and thus also the support 22, the synchronization device 23, and the two arrangements 1 according to the invention, are no longer in a position normal to the longitudinal direction L of the guide rails 4, 17. The cables 6, 19 are therefore subjected to tensile stress.

[0039] An overload occurs on the ropes 6 and 19, which is compensated for by the fastening devices 7 and 20. Without the fastening devices 7 and 20, the ropes 6 and 19 could be damaged.

[0040] Figure 3Figure 1 shows a further embodiment of the invention in a schematic side view.

[0041] Fastening devices 7, 20 are arranged at all ends of the guide rails 4, 17, 16, 160, 21, 210.

[0042] The ropes 6, 19 are each attached on both sides to the stationary furniture part 3 by the associated fastening devices 7, 20 and by the guide rails 4, 17.

[0043] The ropes 6, 19 are further coupled to the guide devices 5, 18 via the coupling devices 27.

[0044] Figure 4 Figure 1 shows a further embodiment of the invention in a schematic side view.

[0045] This embodiment differs from the embodiment shown above. Figure 3by providing two ropes 6, 60 and 19, 190 respectively per guide device. These ropes 6, 60, 19, 190 are in turn attached to the ends 16, 160, 21, 210 of the guide rails 4, 17 by the associated fastening devices 7, 20 and by the guide rails 4, 17 to the stationary furniture part 3.

[0046] Furthermore, the ropes 6, 60, 19, 190 are coupled to the respective guide devices 5, 18 by means of the coupling devices 27.

[0047] Figure 5 shows an arrangement according to the invention in a perspective view.

[0048] A guide device 5, 18, which is movable on the guide rail 4, 17, an end of the fastening device 7, 20 and the support 22 can be seen.

[0049] Furthermore, at least the first rope 6, 19 is shown, which is mounted on the bearing device 8 by means of the notch 12.

[0050] Figure 6shows an arrangement according to the invention in a perspective exploded view.

[0051] This figure primarily illustrates the construction of the fastening device 7, 20.

[0052] In this embodiment, the elastic means 9, designed as a compression spring, is arranged in a base body 10 of the fastening device 7, 20. It is also conceivable that the base body 10 is at least partially enclosed by the elastic means 9.

[0053] In this embodiment, the bearing device 8 and the slide 13 are combined in a single component. However, separate designs of the bearing device 8 and the slide 13 are also possible.

[0054] In this embodiment, the bearing device 8 has a slot-shaped recess 12 for storing the rope 6, 19. However, the shape of the recess 12 can be arbitrarily designed.

[0055] Furthermore, the guide rail 4, 17 as well as the guide device 5, 18 and the support 22 are visible.

[0056] Figure 7 Figure 1 shows an embodiment of an arrangement 1 according to the invention in a side view. For better understanding of the invention, part of the fastening device 7, 20 has been cut out.

[0057] The rope 6, 16 is coupled via the coupling device 27 to the guide device concealed by the guide rail 4, 17.

[0058] Furthermore, the rope 6, 19 is connected to the fastening device 7, 20 by means of the sled 13 and the bearing device 8.

[0059] In this embodiment, the rope 6, 19 is not arranged partially within the elastic means 9 designed as a spring.

[0060] The base body 10 of the fastening device 7, 20 is connected to the guide rail 4, 17 by means of the interfaces 15.

[0061] Furthermore, the support 22 connected to the non-visible guide device 5, 18 is recognizable.

[0062] Figure 8 Figure 1 shows an embodiment of an arrangement 1 according to the invention in a side view under an overload condition. For better understanding of the invention, part of the fastening device 7, 20 has been cut out.

[0063] In the event of an overload, the cable 6, 19 is subjected to a tensile force. This tensile force moves the bearing device 8 and thus the carriage 13 against a force applied by the elastic means 9, which is designed as a spring, parallel to a longitudinal direction of the guide device 4, 17.

[0064] The resulting overload is therefore compensated by the movement of the bearing device 8 and additionally by the elastic means 9.

[0065] This ensures that the rope 6, 19 is not damaged in the event of overload and that the connection between the rope 6, 19 and the stationary furniture part 3 is not loosened.
