Description

[0001] The present invention relates to a guide system for guiding at least one movable door leaf, in particular a folding sliding door, relative to a fixed piece of furniture, comprising: at least one support for the movable mounting of the at least one door leaf, at least one guide rail to be attached to the fixed part of the furniture for guiding the at least one support, at least one guide device for the slidable mounting of the at least one support along the guide rail, at least one carriage which can be coupled to the at least one door leaf, at least one receiving device for receiving the at least one carriage, wherein the at least one receiving device and the at least one support are designed as separate building units and can be attached to each other.

[0002] Furthermore, the invention relates to a piece of furniture with a fixed furniture part and at least two furniture parts movable relative to the fixed furniture part, wherein the at least two furniture parts are movable relative to the fixed furniture part by means of a guide system of the type to be described.

[0003] Furthermore, the invention relates to a method for assembling a guide system of the type to be described.

[0004] WO 2018 / 204947 A1 discloses a guide system according to the preamble of claim 1. AT 521133 B1 discloses a further guide system according to the preamble of claim 1, wherein the receiving device for receiving the carriage and the support, which is movable in a depth direction of the furniture body, are designed as separate components that are to be attached to one another. In an assembled state, the receiving device and the support are mounted so as to be movable relative to each other in a longitudinal direction of the support, such that these components can be decoupled from each other by a load on the other component. To assemble the receiving device, it must be slid in a longitudinal direction onto the support pre-mounted on the furniture until a projection arranged on the support engages in a recess arranged on the receiving device (see Fig. 6a (AT 521133 B1). Mounting the mounting device on the beam can be relatively complex, especially if the beam is of considerable length and access is difficult.

[0005] The object of the present invention is to provide a guide system of the type mentioned above, avoiding the disadvantages discussed above, and simplifying the mounting of the receiving device on the carrier.

[0006] This is achieved according to the invention by the features of claim 1. Further advantageous embodiments of the invention are defined in the dependent claims.

[0007] According to the invention, the at least one support has an interface for attaching the at least one receiving device, wherein the interface is designed such that the at least one receiving device and the at least one support can be attached to each other by sliding them in a sliding direction parallel to the at least one guide rail.

[0008] In other words, the receiving device can be connected to the support by a movement in a direction transverse, preferably perpendicular, to a longitudinal direction of the support, so that the receiving device can be slid or snapped onto the support, for example from the front, with the support pre-mounted on the furniture body.

[0009] This simplifies assembly because the mounting device does not need to be positioned on the support from above, which would also require a relatively large ceiling height. In contrast, the invention allows the mounting device to be connected to the support by a substantially horizontal sliding movement, without the need to position the mounting device on the support from above.

[0010] To secure the receiving device to the carrier, at least one locking device can be provided, by which the receiving device can be locked to the carrier, preferably releasably.

[0011] The interface can have at least one guide for guiding the at least one receiving device, wherein preferably the at least one guide is designed in a substantially U-shape in a cross-sectional plane perpendicular to a longitudinal extension of the at least one support. This enables precise linear movement of the receiving device when it is slid onto the support in the sliding direction for assembly.

[0012] The interface can have at least one stop to limit the sliding movement of the at least one receiving device.

[0013] According to one embodiment, at least one play-compensating element can be provided with which play between the at least one receiving device and the at least one support in a direction parallel to the at least one guide rail can be compensated. Preferably, the at least one play-compensating element is arranged on the at least one receiving device. It is particularly preferred that at least two play-compensating elements are arranged on opposite sides of the at least one receiving device.

[0014] According to one embodiment, at least one mounting part is provided for mounting the at least one door leaf to the at least one support, wherein the at least one mounting part has at least one counter stop with which the at least one receiving device can be locked against the sliding direction. Preferably, the at least one mounting part comprises at least two hinges for the movable mounting of the at least one door leaf.

[0015] The furniture according to the invention has a fixed furniture part and at least two door leaves that are movable relative to the fixed furniture part, wherein the at least two door leaves can be guided relative to the fixed furniture part by a guide system of the type described.

[0016] Further details and advantages of the present invention will become apparent from the following description of the figures. Figs. 1a, 1b show a perspective view of a piece of furniture with a furniture body and furniture parts that can be moved relative to it; Figs. 2a, 2b show the furniture according to the Figuren 1a, 1b In further positions of the furniture parts relative to each other, Fig. 3 shows the guide system in a perspective view, wherein the receiving device is detachably locked to the longitudinal rail, Figs. 4a, 4b show the furniture with the guide rails attached to the stationary furniture part as well as an enlarged detail view thereof, Figs. 5a, 5b show the receiving device to be attached to the support in a perspective view and the receiving device attached to the support in a cross-sectional view, Figs. 6a, 6b show a piece of furniture with a concealed door leaf, which is to be attached to the support via a separate mounting part, as well as an enlarged detail view thereof, Figs. 7a, 7b show the furniture according to Fig. 6a, 6b a view from the rear as well as an enlarged detail view.

[0017] Fig. 1a Figure 1 shows a perspective view of a piece of furniture 1 with a furniture body 2 and a folding-sliding door, which has movable door leaves 3a, 3b; 4a, 4b. The door leaves 3a, 3b and 4a, 4b are movably mounted by a guide system 5 between a first position, in which the door leaves 3a, 3b; 4a, 4b are essentially coplanar to each other, and a second position, in which the door leaves 3a, 3b; 4a, 4b are essentially parallel to each other. In the second (parallel) position, the door leaves 3a, 3b can be slid into a lateral receiving compartment 8a of the furniture body 2, while the door leaves 4a, 4b can be received in a further receiving compartment 8b in a position parallel to each other. The functionality is explained below using door leaves 3a and 3b as examples, whereby the same explanations apply to the other door leaves 4a and 4b.The guide system 5 comprises a longitudinal rail 7 with a longitudinal direction (L), wherein a carriage 6, which can be coupled to the second door leaf 3b, is movably mounted along the longitudinal rail 7. In its assembled state, the longitudinal rail 7 is oriented essentially horizontally and parallel to a front edge of the furniture carcass 2.

[0018] Fig. 1b The furniture shown is 1, with the door leaves 3a, 3b extending from the in Fig. 1a The two door leaves 3a, shown in the coplanar position, were moved to an angled position relative to each other. The first door leaf 3a can, for example, be movably mounted on a support 11 via two or more hinges 10, the support 11 being slid into the receiving compartment 8a in a depth direction (Z). In the figure shown, the support 11 is in a transfer position, so that the carriage 6 can be moved back and forth between the longitudinal rail 7 and the support 11.

[0019] In the transfer position shown, the support 11 is detachably locked to the longitudinal rail 7, the locking mechanism between the longitudinal rail 7 and the support 11 being releasable by the carriage 6 entering or being placed on the support 11. The support 11 can be 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. The two door leaves 3a, 3b are pivotally connected to each other about a vertical axis via at least one hinge fitting 9. The second door leaf 3b is mounted to move along the longitudinal rail 7 via the carriage 6.

[0020] Fig. 2a Figure 1 shows the furniture 1 with the door leaves 3a and 3b, which are now aligned parallel to each other. The support 11 was unlocked from the longitudinal rail 7 by the entry of the carriage 6, so that the support 11 (together with the carriage 6 and the door leaves 3a, 3b) moves in the depth direction (Z) along at least one guide rail 17, 18 running transversely to the longitudinal direction (L) of the longitudinal rail 7. Fig. 3 ) of the guidance system 5 can be inserted into the receiving compartment 8a.

[0021] Fig. 2b Figure 1 shows furniture 1 with door leaves 3a and 3b, which are now in a fully retracted position in the receiving compartment 8a. The door leaves 3a and 3b are thus guided by the guide system 5 from a first position according to... Fig. 1a , in which the door leaves 3a, 3b are essentially coplanar to each other, and a second position according to Fig. 2b , in which the door leaves 3a, 3b are essentially aligned parallel to each other and are movably mounted within the receiving compartment 8a. In this way, for example, a configuration as in the Figuren 2a, 2b The kitchen 12 shown is completely covered, so that it can be visually separated from the rest of the living space. In the illustrated embodiment, the receiving compartment 8a is formed by a side wall 13a and a fixed furniture part 13b spaced parallel to the side wall 13a, wherein the door leaves 3a, 3b can be inserted between the side wall 13a and the fixed furniture part 13b in a position parallel to each other.

[0022] Fig. 3 Figure 1 shows a perspective view of the guide system 5 in the area of ​​the side wall 13a and the fixed furniture part 13b, between which the receiving compartment 8a for receiving the door leaves 3a, 3b is formed. The longitudinal rail 7 has a longitudinal direction (L) which, in a mounting position, runs parallel to a front edge of the furniture body 2. A guide rail 17 with a longitudinal direction (L2) is mounted on the fixed furniture part 13b, wherein the longitudinal direction (L) of the longitudinal rail 7 and the longitudinal direction (L2) of the guide rail 17 run transversely, preferably substantially at right angles to each other.

[0023] The support 11 is designed for the movable mounting of the door leaf 3a, wherein the door leaf 3a is, for example, mounted via two or more hinges 10 ( Fig. 1b The support 11 is pivotably mounted about an axis running vertically in the mounting position. The support 11 has at least one guide device 14 by which the support 11 can be moved along the guide rail 17 in the depth direction (Z) and in a direction opposite to the depth direction (Z). In the figure shown, the guide device 14 of the support 11 has at least one roller 14a, which is movably mounted along a first tread 17a of the guide rail 17.

[0024] The carrier 11 can be detachably locked to the longitudinal rail 7 via a receiving device 15. The receiving device 15 is designed to receive the carriage 6, which is movable between the longitudinal rail 7 and the receiving device 15. For this purpose, guide grooves 20, 21 can be formed in the longitudinal rail 7, which extend in the longitudinal direction (L) of the longitudinal rail 7 and which, in the transfer position of the receiving device 15, are aligned with corresponding guide grooves 20a, 21a of the receiving device 15. In this way, the rollers 6a of the carriage 6 can move without a disruptive impact edge between the longitudinal rail 7 and the receiving device 15.

[0025] The receiving device 15 is movably mounted relative to the support 11 in the longitudinal extent (L1) of the support 11. In this way, the receiving device 15 and the support 11 are displaceable relative to each other in the longitudinal extent (L1) of the support 11, so that the receiving device 15 is decoupled from unwanted torsional movements or lowering movements of the support 11 by a mechanical force exerted on the support 11 (for example, by the weight of the door leaf 3a or by an adjustment device for setting a position of the door leaf 3a). This results in the guide grooves 20, 21 of the longitudinal rail 7 and the guide grooves 20a, 21a of the receiving device 15 always remaining aligned with each other in the transfer position when the carrier 11 is lowered or twisted, thus ensuring precise displacement of the carriage 6 between the longitudinal rail 7 and the receiving device 15.

[0026] To improve the decoupling between the receiving device 15 and the support 11, the receiving device 15 may have at least one support roller 16a separate from the guide device 14 of the support 11, which is movably mounted along the guide rail 17. Preferably, the guide rail 17 has a first tread 17a and at least one second tread 17b separate from the first tread 17a, wherein the roller 14a of the guide device 14 is movably mounted along the first tread 17a of the guide rail 17 and the at least one support roller 16a of the receiving device 15 is movably mounted along the second tread 17b of the guide rail 17.

[0027] The support 11 and the receiving device 15 are coupled to each other during movement along the guide rail 17 in the depth direction (Z), preferably being coupled without play during movement along the guide rail 17 in the depth direction (Z) and in a direction opposite to the depth direction (Z). For improved support of the support 11, at least one further guide rail 18 may be provided, along which at least one further roller 19 of the support 11 is movably mounted.

At least one, preferably two or more, guide rails 17, 18 for the movable support of the carrier 11 are attached to the fixed furniture part 13b. The carrier 11 and the receiving device 15 for the carriage 6 are designed as separate and attachable units.

[0029] In the illustrated embodiment, at least one further guide rail 22 is provided for guiding the receiving device 15, wherein the guide rail 22 is arranged parallel to the guide rails 17, 18 for guiding the support 11. The vertically extending elongated support 11 is movable along the guide rails 17, 18 by means of a scissor mechanism 24.

[0030] Fig. 4b shows the in Fig. 4a The framed area is shown in an enlarged view. The support 11 has an interface 23 for attaching the receiving device 15, the interface 23 being designed such that the receiving device 15 and the support 11 can be attached to one another by sliding them in a sliding direction (SR) (i.e., in the depth direction (Z)) parallel to at least one guide rail 17, 18. The interface 23 can have at least one guide 23a for guiding the receiving device 15. The guide 23a can be substantially U-shaped in a cross-sectional plane perpendicular to the longitudinal extent (L1) of the support 11. The interface 23 has at least one stop 25 by which movement of the receiving device 15 on the support 11 in the sliding direction (SR) can be limited.

[0031] The receiving device 15 can comprise several support rollers 16a, 16b, wherein the support rollers 16a are rotatable about a horizontal axis and the support rollers 16b are rotatable about a vertical axis in a mounted state of the receiving device 15.
