[0001] Arrangement for guiding a movable furniture part
[0002] The present invention relates to an arrangement for guiding a movable furniture part, preferably a sliding door or folding-sliding door, having the features of the preamble of claim 1. The invention further relates to a piece of furniture having such an arrangement and a method for compensating a tipping moment using such an arrangement.
[0003] Basically, the challenge when guiding a sliding door or folding sliding door on a furniture wall is that the sliding door or folding sliding door tends to tilt due to its weight and the resulting tipping moment, which subsequently leads to the door becoming wedged between the vertically spaced guides of the guide systems and thus makes it impossible or at least significantly more difficult to move the door.
[0004] A variety of arrangements are known from the prior art that propose a compensation device for compensating such a tilting moment in order to avoid the negative effects described above. For example, DE 28 47 578 A1 discloses a compensation device with a cable pull device. The cable pull device has a cable that can absorb loads resulting from the tilting moment.
[0005] Particularly with folding / sliding doors, such an arrangement presents the problem that in the closed position—i.e., when the door leaf or leaves of the folding / sliding door are closed—the tilting moment no longer acts in the same plane as the guides of the guide system. As a result, a cable of the cable pull device is no longer sufficiently loaded, meaning that the folding / sliding door can no longer be held in position by the compensation device. This can make opening the folding / sliding door more difficult. It can also result in increased wear and a visually unattractive overall appearance.
[0006] The applicant's own AT 522708 solves this problem by means of a pivoting lever mechanism which is provided in addition to the cable pulling device.
[0007] The disadvantage is the relatively complex construction of such a pivoting lever mechanism, which also requires a lot of space. Furthermore, the assembly of such an arrangement is difficult and time-consuming. Finally, a pivoting lever mechanism is also costly.
[0008] The object of the present invention is to provide an arrangement for guiding a movable furniture part, preferably a sliding door or folding sliding door, which is improved compared to the prior art, a piece of furniture with such an arrangement and a method for compensating a tipping moment with such an arrangement
[0009] These objects are achieved by the features of claims 1 , 17 and 18 .
[0010] In the arrangement for guiding a sliding door or folding-sliding door on a furniture wall, at least one pre-tensioning device is provided, via which the support can be subjected to a force, preferably in the direction of a longitudinal extension of the guide of at least one of the guide systems, at least in a closed position of the movable furniture part. The support can therefore be subjected to a force via the pre-tensioning device. This places load on the cable of the cable pull device again, so that the cable pull device functions as intended even in a closed position and a folding-sliding door can be held in position.
[0011] Compared to the known solution, both the complexity and space requirements as well as the manufacturing costs of an arrangement according to the invention can be reduced.
[0012] According to the invention, a piece of furniture is further provided with at least one fixed furniture part, at least one movable furniture part, preferably a sliding door or folding sliding door, and at least one arrangement according to the invention for guiding the movable furniture part on the fixed furniture part, preferably wherein the movable furniture part can be arranged in a shaft-shaped cavity of the furniture.
[0013] With regard to a method for assembling an arrangement according to the invention, it is provided that in an open position and when moving the support or a movable furniture part arranged thereon between an open position and a closed position, loads resulting from a tilting moment are absorbed by the cable pulling device, wherein the support is brought into contact with the pretensioning device at least in the closed position, preferably shortly before reaching the closed position or an intermediate position, which exerts a force on the support, preferably in the direction of a longitudinal extension of the guide of at least one of the guide systems.
[0014] Further advantageous embodiments of the invention are defined in the dependent claims. It can be provided that the pretensioning device has at least one energy accumulator, preferably a spring, particularly preferably a compression spring. In particular, if a spring or compression spring is provided, this represents a simple possibility for implementing a pretensioning device.
[0015] Preferably, the pretensioning device can be provided with at least one plunger for contacting the carrier. This also contributes to a simple and cost-effective design of the pretensioning device.
[0016] If the pretensioning device has at least one energy accumulator and at least one plunger, the pretensioning device is essentially designed as a spring plunger.
[0017] It can be provided that the pre-tensioning device is arranged on the fixed furniture part and / or the second guide system.
[0018] Alternatively, the pretensioning device can be arranged on the carrier.
[0019] The position of the pre-tensioning device can therefore be selected as best as possible depending on external conditions, for example the space available in a piece of furniture.
[0020] Preferably, it can be provided that a force between 10 N and 20 N, preferably 30 N, can be exerted on the carrier via the pretensioning device.
[0021] It has been shown that such a force is sufficient to tension a rope of a rope pulling device accordingly and thus to ensure perfect functioning of the compensation device even in a closed position.
[0022] It can further be provided that the pretensioning device is a
[0023] Housing includes .
[0024] It has proven advantageous if the energy accumulator is arranged in the housing and / or the plunger is movably mounted in the housing.
[0025] Particularly preferably, it can be provided that the carrier can be subjected to a force in the region of a lower end of the carrier via the pretensioning device at least in a closed position.
[0026] As a result, the pre-tensioning device acts on a beam essentially at the same point as a tilting moment, allowing the compensation device to act accordingly.
[0027] Preferably, the at least one cable pulling device can comprise at least one, preferably exactly one, cable, which is attached to the support at one end, preferably at both ends. If only one cable is provided, the construction and assembly of the arrangement are simplified even further.
[0028] It can further be provided that the at least one cable pulling device has at least one cable tensioning device with which the tension of a cable of the at least one cable pulling device can be adjusted, preferably with the at least one cable tensioning device being arranged on the support. It can further be provided that the at least one cable pulling device has at least one deflection device, preferably with a deflection pulley, by means of which a cable of the at least one cable pulling device can be deflected.
[0029] These measures facilitate the installation of the rope and improve the stability and rigidity of the arrangement.
[0030] According to a further embodiment of the invention, the at least one deflection device can be arranged or can be arranged on the fixed furniture part and / or a guide system.
[0031] Preferably, the compensation device can be at least partially, preferably completely, pre-assembled on the support in the delivery state of the assembly. This significantly facilitates the assembly of the assembly on a fixed piece of furniture.
[0032] According to a further embodiment, it can be provided that the energy accumulator acts between the carrier and a cable end of the cable, preferably wherein the cable is arranged at least partially within the energy accumulator.
[0033] In this case, the cable of the cable pulling device is pre-tensioned via the pre-tensioning device so that the cable pulling device also functions perfectly in the closed position.
[0034] Furthermore, it can be provided that the pre-tensioning device comprises a stop, wherein the stop is arranged on the fixed furniture part, wherein at least in a closed position a stop plate arranged on the support can be brought into contact with the stop (25). This stop serves to compensate for any distance between
[0035] To reliably bridge the support and the fixed furniture part in the shooting position.

[0051] Figure 1a shows a schematic, perspective view of a piece of furniture 100 in an open position, Figure 1b shows the corresponding intermediate position and Figure 1c shows the corresponding closed position.
[0052] A cavity 101 is provided on the side of the furniture 100, which is formed by two spaced-apart furniture walls 101a. A movable furniture part 2, in this exemplary embodiment a folding-sliding door, can be lowered into this cavity 101 when folded. When the folding-sliding door 2 is spread open, it conceals the interior 100a of the furniture 100.
[0053] The movable furniture part 2 is composed of two door leaves 2a, which are folded together in the positions shown in Figures 1b and 1c. From the intermediate position shown in Figure 1b, the movable furniture part 2 can be moved into a closed position in which the door leaves 2a form an angle greater than 0° (Figure 1c).
[0054] Figure 2 shows a schematic, perspective view of a part of a piece of furniture 100 in an intermediate position. An arrangement 1 can be seen which has two guide systems 4, 6 arranged on a furniture wall 101a. The first guide system 4 is arranged at a vertical distance 5 from the second guide system 6.
[0055] The guide systems 4, 6 each comprise a guide 7, 8 and an associated guide body 9, 10. The guide bodies 9, 10 are movably mounted on the associated guide 7, 8. The guide bodies 9, 10 are further connected to a support 11, so that the support 11 is movably mounted on the fixed furniture part 3 via the guide systems 4, 6.
[0056] On the support 11, several hinges 14 are provided, via which a movable furniture part 2 is pivotally mounted on the support 11.
[0057] In addition, a cable 18 of the cable pulling device 16 can be seen.
[0058] Figure 3a shows a schematic, perspective view of a part of a piece of furniture 100 in a closed position, Figure 3b shows detail A of Figure 3a and Figure 3c shows detail B of Figure 3b.
[0059] The furniture 100 is arranged in a closed position so that the movable furniture part 2 covers an interior space 100a of the furniture.
[0060] In this exemplary embodiment, the pretensioning device 17 is arranged on the fixed furniture part 3 (furniture wall 101a) or on the second guide system 6 via a holder 13 for a deflection roller 20 of a deflection device 16b. A stop plate 19 is provided on the support 11, which can be contacted by a plunger 17b of the pretensioning device 17. It can also be provided that the pretensioning device 17 is arranged on the support 11 and the stop plate 19 is arranged on the fixed furniture part 3.
[0061] The pretensioning device 17 can therefore exert a force on the support 11 via the stop plate 19. It can be seen that the pretensioning device 17 already exerts a force on the support 11 in an intermediate position according to Figure 1b. In particular, the plunger 17b can also come into contact with the stop plate 19 shortly before reaching the intermediate position.
[0062] Figure 4a shows a schematic side view of a part of an assembly 1 and a movable furniture part 2. It shows how the tilting moment 12 of the movable furniture part 2 acts on the support 11. The resulting loads can be absorbed and the tilting moment 12 compensated via the cable 18 of the cable pulling device 16.
[0063] A cable tensioning device 16a, which is shown again in Figure 4b, is arranged on the support 11. During assembly of the arrangement 1, the cable 18 is inserted into the cable tensioning device 16a and tensioned. The cable tensioning device 18 can be designed as desired.
[0064] Figure 4c shows detail B of Figure 4a. It can again be seen that the pretensioning device 17 is arranged on a holder 13 for a deflection pulley 20 of a deflection device 16b. The cable 18 is deflected via the deflection pulley 20 and is fastened to a fastening point 19a on the stop plate 19. The cable 18 is thus fastened with this end to the support 11 via the stop plate 19. The other end of the cable 18 can also advantageously be arranged on the support 11.
[0065] Figure 5a shows a schematic, perspective view of a pretensioning device 17, Figure 5b a corresponding exploded view and Figure 5c a corresponding sectional view.
[0066] The pretensioning device 17 comprises a housing 17c. The plunger 17b is guided in the housing 17c and is acted upon by the energy accumulator 17a in the form of a compression spring. A cover cap 17e, which is fixed in the housing 17c by a locking pin 17f, serves as a counterbearing for the energy accumulator 17a.
[0067] The pretensioning device 17 can be attached to the holder 13 via fastening means 17d, here in the form of screws, which can be passed through openings in the housing 17c. However, in principle, any suitable means can be used as fastening means 17d.
[0068] Fig. 6a shows a schematic view of another embodiment of a pretensioning device 17. The pretensioning device can be seen from a side facing away from the furniture wall 101a. Fig. 6b shows a view from a side facing the furniture wall 101a.
[0069] In this exemplary embodiment, the pretensioning device 17 comprises a force accumulator 17a in the form of a compression spring. The cable 18 is guided through the force accumulator 17a, with a cable termination 18a resting against one end of the force accumulator 17a. The other end of the force accumulator 17a rests against an angle 17g, which is arranged on the support 11 or is directly or indirectly connected to it. The cable 18 is thus mounted on the support 11 via the pretensioning device 17.
[0070] The support 11 is only partially shown in Figs . 6a and 6b since it would cover a large part of the pretensioning device 17, at least in Fig . 6a.
[0071] Furthermore, a stop 25 can be seen which is fastened to the holder 13. The stop plate 19 arranged on the support 11 can come into contact with this stop 25, at least in a closed position. In this exemplary embodiment, the energy accumulator 17a therefore exerts a force parallel to the longitudinal extent of a guide 7, 8 on the angle 17g and thus on the support 11. This presses the stop plate 19 against the stop 25 so that it always rests against the stop 25 in the closed position. This also puts the cable 18 of the cable pull device 16 under load again so that the cable pull device 16 functions as intended even in a closed position and a folding / sliding door can be held in position.
[0072] The stop 25 can be made of a plastic, for example. This improves the damping properties of the stop 25 and results in lower noise levels when the stop plate 19 strikes the stop 25.
[0073] In Figs. 6a and 6b, a support roller 21 can also be seen. The support roller 21 is rotatably mounted on a lever 22. The lever 22 is pivotally mounted on the holder 13 and pretensioned in the direction of the cable 18 by a spring 23, here a torsion spring. As a result, the cable 18 is pretensioned via the support roller 21, which assists the pretensioning device 17.
