[0001] Guide system for guiding at least one movably mounted door leaf along a furniture wall
[0002] The present invention relates to a guide system for guiding at least one movably mounted door leaf along a furniture wall, comprising:
[0003] - a first guide rail to be attached to the furniture wall,
[0004] - at least one second guide rail to be fixed to the furniture wall at a vertical distance from the first guide rail,
[0005] - a support for pivotally supporting at least one door leaf,
[0006] - at least one first guide device by which the carrier is movably mounted along the first guide rail,
[0007] - at least one second guide device by which the carrier is movably mounted along the second guide rail,
[0008] - a cable pulling device for compensating a tilting moment of the beam about a tilting axis by a restoring moment.
[0009] Such guide systems are usually used to guide at least one door leaf, which can be inserted in a depth direction of the furniture along a furniture wall into a furniture body or into a receiving compartment located laterally next to the furniture body.
[0010] A particular challenge in guiding such a door leaf is that the door leaf tends to tilt due to its weight. Such tilting of the door leaf also leads to a slanted position of the support and to a tilting of the two guide devices, which can cause the guide devices to jam with their associated guide rails. In the event of such a jam, movement of the door leaf is impossible or at least significantly hampered. A primary goal is therefore to ensure that the two guide devices are guided relative to their associated guide rails in a way that is largely secure against tilting.
[0011] Guide systems for a door leaf with a cable pull device for tilt-free guidance of a door leaf are shown, for example, in US 2007 / 0159037A1 (Fig. 4), in WO 2018 / 129568 A1 (Fig. 5a), in DE 197 09 461 A1 (Fig. 5), in EP 1 394 349 A1 (Fig. 1), and in EP 0 128 503 A1 (Fig. 3). To improve the stability of the two guide devices relative to one another, a crosswise cable guide is advantageous, for which at least two cables are provided. However, the installation of two cables is complicated for an installer and also involves increased component complexity.
[0012] The object of the present invention is to provide a guidance system of the type mentioned at the outset while avoiding the disadvantages discussed above.
[0013] This is achieved according to the invention by the features of patent claim 1. Further advantageous embodiments of the present invention are defined in the dependent claims.
[0014] According to the invention, it is provided that the cable pulling device has at least one, preferably exactly one, cable, wherein the cable is guided crosswise over at least two deflection pulleys arranged on the two guide devices and / or on at least one carrier.
[0015] The prior art mentioned above does provide for a cross-shaped cable guide, but this requires at least two cables. With the present invention, however, a single cable is generally sufficient to form a cross in the cable guide. This significantly simplifies the assembly of the cable pulling device.
[0016] The piece of furniture according to the invention comprises a furniture body, at least one door leaf movable relative to the furniture body and at least one guide system of the type in question.
[0017] Further details and advantages of the present invention will become apparent from the following description of the figures.
[0018] Fig. 1a, 1b show a perspective view of a piece of furniture with a furniture body and door leaves movable relative thereto,
[0019] Fig. 2a, 2b show the furniture according to Figures 1a, 1b in further positions of the door leaves relative to each other,
[0020] Fig. 3 shows the guide system in a perspective view,
[0021] Fig. 4 shows the guidance system in a schematic side view,
[0022] Fig. 5 shows the guide system with the cable pulling device in a schematic side view,
[0023] Fig. 6a, 6b show the cable pulling device in a perspective view and an enlarged detailed view thereof,
[0024] Fig. 7a, 7b show the cable pulling device in a further perspective view as well as an enlarged detailed view thereof,
[0025] Fig. 8a, 8b show two different embodiments of an inclination adjustment device by which an inclination of the support relative to a vertical can be adjusted. Fig. 1a shows a perspective view of a piece of furniture 1 with a furniture body 2 and at least one door leaf 3a, 3b; 4a, 4b mounted so as to be movable relative to the furniture body 2.
[0026] In the illustrated embodiment, a folding-sliding door is provided, with the door leaf 3a and the door leaf 3b being hinged together via a vertically extending first pivot axis. The other two door leaves 4a, 4b are hinged together via a vertically extending second pivot axis.
[0027] The door leaves 3a, 3b and the door leaves 4a, 4b are each movable by a guide system 5 between a first position in which the door leaves 3a, 3b; 4a, 4b are aligned substantially coplanar to one another, and a second position in which the door leaves 3a, 3b; 4a, 4b are aligned substantially parallel to one another.
[0028] The door leaves 3a, 3b can be inserted in a second (parallel) position into a lateral receiving compartment 8a of the furniture body 2, while the two other door leaves 4a, 4b can be inserted in a parallel position to each other into a further receiving compartment 8b.
[0029] The functionality is explained below using door leaves 3a and 3b, whereby the same explanations apply to door leaves 4a, 4b.
[0030] The guide system 5 comprises a guide 7 with a longitudinal direction
[0031] L, wherein a carriage 14, which can be coupled to the second door leaf 3b, is mounted so as to be movable along the guide 7. In an assembled position, the guide 7 is aligned essentially horizontally and parallel to a front edge of the furniture body 2.
[0032] Preferably, the guide 7 is designed as a guide rail.
[0033] Fig. 1b shows the piece of furniture 1, wherein the door leaves 3a, 3b have been moved from the coplanar position shown in Fig. 1a into an angular position relative to each other.
[0034] The first door leaf 3a can, for example, be pivotally mounted on a support 11 via two or more furniture hinges 10, wherein the support 11 (together with the two door leaves 3a, 3b) can be inserted into the receiving compartment 8a in the depth direction Z.
[0035] In the figure shown, the carrier 11 is in a transfer position in which the carrier 11 is connected to the guide 7 in the longitudinal direction L in such a way that the carriage 14 can be transferred back and forth between the guide 7 and the carrier 11.
[0036] In the transfer position shown, the carrier 11 is releasably locked relative to the guide 7, wherein the locking of the carrier 11 can be released by the carriage 14 entering or onto the carrier 11.
[0037] The support 11 is designed in the form of an elongated column, the length of which corresponds to at least half the height of the door leaves 3a, 3b.
[0038] The two door leaves 3a, 3b are articulated to one another via at least one hinge fitting 9 about an axis of rotation which runs vertically in the assembled position. The second door leaf 3b is guided so as to be movable along the guide 7 via the carriage 14. Fig. 2a shows the piece of furniture 1 with the door leaves 3a and 3b, which are now aligned parallel to one another. The support 11 has been unlocked from the guide 7 by the carriage 14 entering, so that the support 11 (together with the carriage 14 and the door leaves 3a, 3b) can be pushed into the receiving compartment 8a in the depth direction Z along at least two guide rails 12a, 12b (Fig. 3) of the guide system 5 which are spaced apart from one another in the height direction.
[0039] Fig. 2b shows the piece of furniture 1 with the door leaves 3a, 3b, which are now in a fully inserted state in the receiving compartment 8a. The door leaves 3a, 3b are thus movably mounted by the guide system 5, starting from a first position according to Fig. 1a, in which the door leaves 3a, 3b are aligned substantially coplanar to one another, and a second position according to Fig. 2b, in which the door leaves 3a, 3b are aligned substantially parallel to one another and can be accommodated within the receiving compartment 8a.
[0040] In this way, for example, a kitchen 37 as shown in Figures 2a, 2b can be completely covered, so that the kitchen 37 can be visually separated from the remaining area of a living space.
[0041] In the exemplary embodiment shown, the receiving compartment 8a is formed by a first furniture wall 13a and by a second furniture wall 13b which is spaced apart substantially parallel from the first furniture wall 13a, wherein the door leaves 3a, 3b can be received in a parallel position to one another between the two furniture walls 13a, 13b.
[0042] Fig. 3 shows the guide system 5 in a perspective view. The guide 7 allows the door leaves 3a, 3b to be guided along an end face of the furniture body 2. The support 11 is designed for pivotally supporting the first door leaf 3a and can have at least one furniture hinge 10 or several furniture hinges 10, which are spaced apart from one another in a longitudinal direction of the support 11.
[0043] The carrier 11 is mounted so as to be movable in the depth direction Z via a first guide device 19a along a first guide rail 12a and via a second guide device 19b along a second guide rail 12b.
[0044] The carrier 11 and / or the guide devices 19a, 19b can have or can have at least one rolling element 35 (Fig. 8a, Fig. 8b) which is mounted so as to be movable along a guide rail 12a, 12b.
[0045] It is preferably provided that the carrier 11 and / or the guide devices 19a, 19b have or have a plurality of rolling elements 35 which are rotatably mounted about an axis running horizontally in the assembled position and / or about an axis running vertically in the assembled position and which can roll on a guide rail 12a, 12b.
[0046] In the illustrated embodiment, at least one further guide rail 12c is provided, which is spaced apart in a vertical direction from the two guide rails 12a, 12b. The guide rails 12a, 12b, 12c each have a longitudinal direction LI.
[0047] Fig. 4 shows a schematic side view of the guide system 5, wherein the first guide rail 12a and the second guide rail 12b are fastened to the furniture wall 13a, wherein the second guide rail 12b is arranged at a vertical distance 6 from the first
[0048] Guide rail 12a is arranged on the furniture wall 13a. The support 11 is mounted so as to be movable in the depth direction Z via the first guide device 19a along the first guide rail 12a and via the second guide device 19b along the second guide rail 12b.
[0049] At least one door leaf 3a is pivotally mounted on the support 11, with the door leaf 3a being indicated by a dotted line. The support 11 is connected to the two guide devices 19a, 19b in a motion-coupled manner.
[0050] Furthermore, a cable pulling device 15 (Fig. 5) is provided for compensating a tilting moment 16 of the support 11 about a tilting axis 17 by means of a restoring moment 18. When the support 11 or the door leaf 3a is vertically aligned, the tilting axis 17 is horizontally aligned.
[0051] The cable pulling device 15 thus ensures that at least one door leaf 3a is guided stably in every position, without the guide devices 19a, 19b tilting relative to the guide rails 12a, 12b.
[0052] Fig. 5 shows a schematic side view of the guide system 5. The carrier 11 is mounted so as to be movable between a retracted end position and an extended end position in the depth direction Z along the two guide rails 12a, 12b.
[0053] In the figure shown, the support 11 is located approximately in a middle position between the retracted end position and the extended end position. The support 11 is movably mounted along the guide rails 12a, 12b via the two guide devices 19a, 19b. At least two deflection pulleys 24a, 24b for at least one, preferably exactly one, cable 15a of the cable pulling device 15 are rotatably mounted on the support 11 and / or on the guide devices 19a, 19b.
[0054] The reference numerals 23a, 23b, 23c, 23d denote deflection elements, wherein the cable 15a is arranged stationary on the deflection elements 23a, 23b, 23c, 23d, i.e. that in the case of a
[0055] During movement of the support 11 along the guide rails 12a, 12b, essentially no relative movement occurs between the cable 15a and the deflection elements 23a, 23b, 23c, 23d. The deflection elements 23a, 23b, 23c, 23d are arranged on the guide rails 12a, 12b.
[0056] The cable 15a is guided crosswise over the two deflection pulleys 24a, 24b arranged on the two guide devices 19a, 19b and / or on at least one support 11. In this way, a largely jam-free movement of the support 11 and the guide devices 19a, 19b can be ensured.
[0057] The cable 15a of the cable pulling device 15 is guided in the illustrated embodiment as follows:
[0058] - a first rope end 20 of the rope 15a is arranged on the first guide rail 12a, preferably stationary, at the point A,

[0067] To adjust the tension of the cable 15a, at least one adjustment device 25 can be provided, by which the two cable ends 20, 21 of the cable 15a can be tensioned relative to one another. In the illustrated embodiment, the adjustment device 25 is arranged on the second guide rail 12b.
[0068] In order that the cable 15a can be guided twice around the two deflection pulleys 24a, 24b, the two deflection pulleys 24a, 24b have two essentially parallel guide grooves 27a, 27b (Fig. 6b) for guiding the cable 15a, wherein the cable 15a is guided with a first cable section in a first of the two guide grooves 27a, 27b and with a second cable section in a second of the two guide grooves 27a, 27b.
[0069] According to possible embodiments, it can be provided that the rope 15a
[0070] - has a crossing point 22 which is arranged substantially in the middle of the at least one carrier 11, and / or
[0071] - has at least one cable section which is guided between the two guide rails 12a, 12b essentially parallel to the carrier 11, preferably stationary (cable section between point D and point E), and / or
[0072] - has at least one cable section which is guided substantially parallel to a longitudinal direction LI of the first and second guide rails 12a, 12b (cable section between points A and B, cable section between points C and D, cable section between points E and F, cable section between points G and H, cable section between points I and J).
[0073] When the carrier 11 moves between the retracted end position and the extended end position, the carrier 11 can be guided along at least one cable section which runs substantially parallel to a longitudinal direction LI of the first and second guide rails 12a, 12b.
[0074] The cable 15a has a first cable end 20, which is arranged at a first end of the first guide rail 12a. A second cable end 21 of the cable 15a is arranged at a first end of the second guide rail 12b.
[0075] According to possible embodiments, it can be provided that
[0076] - the first end of the first guide rail 12a and the first end of the second guide rail 12b are arranged diametrically to each other, and / or
[0077] - a position of at least one of the two cable ends 20, 21 is adjustable by an adjusting device 25 relative to the first end of the first or second guide rail 12a, 12b, and / or

[0079] According to one embodiment, it can be provided that the cable 15a is guided in such a way that the cable 15a forms a first Z-shape and at least one second Z-shape in a side view of the furniture wall 13a, preferably wherein the two Z-shapes are arranged mirror-symmetrically to one another.
[0080] Fig. 6a shows the cable pulling device 15 according to Fig. 5 in a perspective view, wherein the first cable end 20 of the cable 15a is fastened to the first guide rail 12a at the point A.
[0081] As already described, the cable 15a is guided around the deflection pulleys 24a, 24b and the deflection elements 23a-23d at points B-I. The second cable end 21 is held at point J on the second guide rail 12b, with the tension of the cable 15a being adjustable by an adjusting device 25.
[0082] According to one embodiment, the cable 15a can have at least one cable section that is guided in a substantially U-shaped manner around at least one of the two guide rails 12a, 12b. In the present case, the cable 15a is guided around the second guide rail 12b in a U-shaped manner.
[0083] In principle, routing the cable 15a around the two deflection elements 23c, 23d is not absolutely necessary. However, this measure is advantageous because it provides a reserve of cable, and tensioning the cable 15a can be easily accomplished by the adjustment device 25.
[0084] Fig. 6b shows the area framed in Fig. 6a in an enlarged view. The deflection pulley 24a and / or the deflection pulley 24b has two essentially parallel guide grooves 27a, 27b for guiding the cable 15a. It can be provided that the cable 15a is guided with a first cable section in a first of the two guide grooves 27a, 27b and with a second cable section in a second of the two guide grooves 27a, 27b.
[0085] The deflection rollers 24a, 24b and / or the deflection elements 23a-23d can have at least one, preferably pivotable, safety bracket 26, which is designed to prevent the cable 15a from jumping out of the deflection rollers 27a, 27b and / or out of the deflection elements 23a-23d.
[0086] Preferably, it can be provided that the cable 15a is deflected once, preferably twice, by substantially 90° on at least one deflection pulley 24a, 24b, preferably on both deflection pulleys 24a, 24b.
[0087] In a further embodiment, it can be provided that the cable 15a is deflected by substantially 90° on at least one deflection element 23a-23d, preferably on all deflection elements 23a-23d.
[0088] Fig. 7a shows the cable pulling device 15 in a further perspective view.

The second (lower) deflection pulley 24b can also have two substantially parallel guide grooves 27a, 27b for guiding the cable 15a. The cable 15a is guided with a first cable section in a first guide groove 27a and with a second cable section in the second guide groove 27b.
[0092] The adjustment device 25 at point J for adjusting the tension of the cable 15a can have at least one rotatable adjustment element 28, for example in the form of a clamping screw. However, it is also possible for the adjustment element 28 to be designed as part of a worm gear, wherein the tension of the cable 15a can be variably adjusted by rotating the adjustment element 28.
[0093] Fig. 8a shows a first embodiment of an inclination adjustment device 34, by means of which an inclination of the support 11 can be adjusted relative to a vertical. This inclination adjustment device 34 serves to correct any misalignment of the support 11 and / or any misalignment of the door leaf 3a pivotally mounted on the support 11.
[0094] The inclination adjustment device 34 is preferably located on the second (lower) guide device 19b, wherein the first (upper) guide device 19a itself does not have an inclination adjustment device 34.
[0095] The inclination adjustment device 34 comprises at least one threaded portion 30, which is in threaded engagement with a bearing 31a of the second (lower) guide device 19b and with a counterbearing 31b. The counterbearing 31b is arranged on a pivot lever 33, on which the second (lower) deflection pulley 24b is also mounted. In the assembled position, the second deflection pulley 24b is held in place by the cable 15a, which is guided twice around it.
[0096] When the threaded portion 30 is rotated by means of a tool 32, for example a screwdriver, the guide device 19b (and thus the carrier 11) is moved relative to the stationary second deflection roller 24b. In this way, the position of the carrier 11 relative to a vertical line can also be adjusted.

[0100] In the assembled position, the second deflection pulley 24b is held in place by the rope 15a which is guided twice around it.
[0101] By rotating the threaded portion 30 by means of a tool 32, for example a screwdriver, the relative position between the second guide device 19b and the carrier 11 can be adjusted via at least one linear guide 36, preferably via a plurality of linear guides 36.
[0102] In the illustrated embodiment, the at least one linear guide 36 comprises an elongated hole arranged on the second guide device 19b, in which a guide element arranged on the carrier 11, for example a bolt, is displaceably guided. In kinematic reversal, it is also possible for the elongated hole to be arranged or formed on the carrier 11 and the guide element engaging in the elongated hole to be arranged or formed on the guide device 19b.
