DETAILED DESCRIPTION OF THE INVENTION

(8) FIG. 1a shows a perspective view of an item of furniture 1 comprising a furniture carcass 2 and a folding-sliding-door having movable door wings 3a, 3b; 4a, 4b. The door wings 3a, 3b are movably supported by a guide system 5 between a first position, in which the door wings 3a, 3b; 4a, 4b are aligned coplanar to one another, and a second position, in which the door wings 3a, 3b; 4a, 4b are aligned parallel to one another. The door wings 3a, 3b, in a second (parallel) position, can be inserted into a lateral receiving compartment 8a of the furniture carcass 2. The door wings 4a, 4b, in a parallel position to one another, can be inserted into a further receiving compartment 8b. The functionality will be explained in the following with the aid of the door wings 3a, 3b, and the same explanations apply for the door wings 4a, 4b. The guide system 5 includes a longitudinal rail 7 having a longitudinal direction (L), and a running carriage 6 configured to be coupled to the second door wing 3b is displaceably supported along the longitudinal rail 7. In a mounted position, the longitudinal rail 7 is arranged substantially horizontally and parallel to a front edge of the furniture carcass 2.

(9) FIG. 1b shows the item of furniture 1, and the door wings 3a, 3b have been moved from the coplanar position shown in FIG. 1a into an angled position to one another. The first door wing 3a can be movably supported on a carrier 11, for example by two or more furniture hinges 10. The carrier 11 can be inserted in a depth direction (Z) into the receiving compartment 8a. In the shown figure, the carrier 11 is located in a transfer position, so that the running carriage 6 can be transferred between the longitudinal rail 7 and the carrier 11. In the shown transfer position, the carrier 11 is releasably locked to the longitudinal rail 7, and the locking between the longitudinal rail 7 and the carrier 11 can be released by an entry of the running carrier 6 in or onto the carrier 11. The carrier 11 is in the form of a longitudinally extending column, a length of the column corresponding to at least half of a height of the door wings 3a, 3b. The two door wings 3a, 3b are pivotally connected to one another about a vertically extending axis by at least one hinge fitting 9. The second door wing 3b is displaceably supported along the longitudinal rail 7 via the running carriage 6.

(10) FIG. 2a shows the item of furniture 1 with the door wings 3a, 3b which are now aligned parallel to one another. The carrier 11 has been unlocked from the longitudinal rail 7 by an entry of the running carriage 6, so that the carrier 11 (jointly with the running carriage 6 and the door wings 3a, 3b) can be inserted in the depth direction (Z) along a guide rail 17 (FIG. 3) of the guide system 5 into the receiving compartment 8a, the guide rail 17 extending transversely to the longitudinal direction (L) of the longitudinal rail 7.

(11) FIG. 2b shows the item of furniture 1 with the door wings 3a, 3b which are now located in a fully inserted condition within the receiving compartment 8a. The door wings 3a, 3b are thus movably supported by the guide system 5 between a first position according to FIG. 1a, in which the door wings 3a, 3b are aligned substantially coplanar to one another, and a second position according to FIG. 2b, in which the door wings 3a, 3b are aligned substantially parallel to one another and in which the door wings 3a, 3b can be accommodated within the receiving compartment 8a. In this way, for example, a kitchen 12 as shown in FIG. 2a, 2b can be entirely covered, so that the kitchen 12 can be visually separated from a remaining area of a living room. In the shown embodiment, the receiving compartment 8a is formed by a sidewall 13a and by a stationary furniture part 13b spaced from the sidewall 13a in a parallel relationship. The door wings 3a, 3b, in a parallel position to one another, can be inserted between the sidewall 13a and the stationary furniture part 13b.

(12) FIG. 3 shows a perspective view of the guide system 5 in a region between the sidewall 13a and the stationary furniture part 13b, between which the receiving compartment 8a for receiving the door wings 3a, 3b is formed. The longitudinal rail 7 has a longitudinal direction (L) extending parallel to a front edge of the furniture carcass 2 in a mounted position. A guide rail 17 having a longitudinal direction (L2) is arranged on the stationary furniture part 13b. The longitudinal direction (L) of the longitudinal rail 7 and the longitudinal direction (L2) of the guide rail 17 extend transversely, preferably substantially at a right angle, to one another. The carrier 11 is configured for movably supporting the at least one door wing 3a. In a mounted condition, the door wing 3a is pivotally supported, for example by two or more hinges (FIG. 1b), on the carrier 11 about a vertically extending axis in the mounted position. The carrier 11 includes at least one guiding device 14 for moving the carrier 11 along the guide rail 17 in the depth direction (Z) and in a direction opposite the depth direction (Z). In the shown figure, the guiding device 14 of the carrier 11 includes at least one running wheel 14a movably supported along a first running limb 17a of the guide rail 17.

(13) In the shown embodiment, the carrier 11 can be releasably locked to the longitudinal rail 7 via a receiving device 15. The receiving device 15 is configured so as to receive the running carriage 6, so that the running carriage 6 can be moved from the longitudinal rail 7 into the receiving device 15. For this purpose, guide grooves 20, 21 may be arranged in the longitudinal rail 7. The guide grooves 20, 21 extend in the longitudinal direction (L) of the longitudinal rail 7 and are aligned flush with corresponding guide grooves 20a, 21a of the receiving device 15 when the receiving device 15 is in the transfer position. In this way, the running wheels of the running carriage 6 can be displaced between the longitudinal rail 7 and the receiving device 15 without a disturbing abutting edge.

(14) For the improved decoupling between the receiving device 15 and the carrier 11, it can be provided that the receiving device 15 includes at least one supporting roller 16 separate from the guiding device 14 of the carrier 11, the at least one supporting roller 16 being movable along the guide rail 17. It can be preferably provided that the guide rail 17 includes a first running limb 17a and at least one second running limb 17b separate from the first running limb 17a. The running wheel 14a of the guiding device 14 is movably supported along the first running limb 17a of the guide rail 17, and the at least one supporting roller 16 of the receiving device 15 is movably supported along the second running limb 17b of the guide rail 17.

(15) The carrier 11 and the receiving device 15 are connected to one another in a movement-coupled manner upon a movement along the guide rail 17 in the depth direction (Z). It is preferably provided that the receiving device 15 and the carrier 11, upon a movement along the guide rail 17 in the depth direction (Z) and in a direction opposite the depth direction (Z), are coupled to one another without clearance. For the improved support of the carrier 11, at least one further guide rail 18 may be provided, and a further running wheel 19 of the carrier 11 is displaceably supported along the further guide rail 18.

(16) FIG. 4 shows a perspective view of the guide rail 17 configured to be arranged on the stationary furniture part 13b and to be arranged in the depth direction (Z) of the furniture carcass 2. An adjustment device 25 is arranged on the front end-face of the guide rail 17, the adjustment device 25 having a rotationally supported operating element 26. By rotating of the operating element 26 with the aid of a tool, at least one abutment 28 for determining an end position of the carrier 11 relative to the guide rail 17 can be adjusted. In the shown embodiment, the abutment 28 is formed or arranged on an ejector 36 of an ejection device 27. By overpressing the abutment 28 into an overpressing position arranged behind the end position, the carrier 11 can be ejected in a direction opposite the depth direction (Z) by a force of the ejection device 27.

(17) FIG. 5 shows the guide system 5 in an exploded view. The guide rail 17 has a longitudinal direction (L2), and the at least one abutment 28 is displaceably supported in the longitudinal direction (L2) by an actuation of the adjustment device 25. The operating element 26 is arranged on the front-end of the guide rail 17, the operating element 26 being rotationally arranged on a bearing portion 30, but arranged non-displaceably in the longitudinal direction (L2). For this purpose, the operating element 26 can have an undercut (for example in the form of a recess) in which the bearing portion 30 can be received in a form-locking manner. The bearing portion 30 is configured to be fixed to the front-end region of the guide rail 17 by a first screw 31. The operating element 26 is in threading engagement with a coupling rod 32 via a threaded portion 37, and the coupling rod 32 can be moved in the longitudinal direction (L2) by an actuation of the operating element 26. The coupling rod 32 is connected to the ejection device by a second screw 33, the ejection device 27 being configured to be displaceable in or along at least one linear guide 34a of the guide rail 17. By the ejection device 27, the carrier 11 can be ejected in a direction opposite the depth direction (Z).

(18) In the shown embodiment, two abutments 28 are provided, and each of the abutments 28 is formed or arranged on an ejector 36 of the ejection device 27. Each of the ejectors 36, in a usual manner, includes a lockable force storage member configured to be unlocked by a movement of the abutments 28 into an overpressing position arranged behind the end position. The ejection device 27 further includes an insertion slit 29 for a portion of the carrier 11, so that the position of the carrier 11 can be stabilized in the end position in a direction extending transversely to the longitudinal direction (L2). By applying a force to the furniture parts 3a, 3b in the end position of the carrier 11, the receiving device 15 of the carrier 11 can contact the abutments 28 so as to move them into the overpressing position, so that the force storage members of the ejectors 36 can be unlocked, and the carrier 11 can be ejected in a direction opposite the depth direction (Z) by a force of these force storage members.

(19) FIG. 6a shows the guide system 5 in a side view, in which the carrier 11 adopts a first end position relative to the guide rail 17. By the adjustment device 25, the at least one abutment 28 can be adjusted in the longitudinal direction (L2) of the guide rail 17. For displaceably supporting the abutment 28 and/or the ejection device 27, at least one or a plurality of linear guides 34a, 34b, 34c can be provided. The linear guide 34a is formed on the guide rail 17, whereas the two other linear guides 34b, 34c are arranged on the ejection device 27. By an actuation of the adjustment device 25, the linear guides 34b, 34c can be displaced relative to pins 38a, 38b which are stationarily arranged relative to the guide rail 17.

(20) FIG. 6b shows the guide system 5 with the carrier 11 in a second end position, the second end position deviating from the first end position. By adjusting the abutment 28 for determining an end position of the carrier 11, manufacturing tolerances of the door wings 3a, 3b or a different width of the door wings 3a, 3b can be compensated for. Therefore, a front-end face of the door wings 3a, 3b, in the inserted condition within the receiving compartment 8a of the furniture carcass 2, can be aligned flush relative to the front end faces of the sidewall 13a and of the stationary furniture part 13a. According to an embodiment, it can be provided that the at least one abutment 28 can be adjusted by the adjustment device 25 between 0 mm and 50 mm, preferably between 0 mm and 130 mm.
