DETAILED DESCRIPTION OF THE INVENTION

(9) 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 and the door wings 4a, 4b are movably supported by a guide system 5 between a first position, in which the door wings 3a, 3b; 4a, 4b are aligned substantially coplanar to one another, and a second position, in which the door wings 3a, 3b; 4a, 4b are aligned substantially parallel to one another. In the second (parallel) position, the door wings 3a, 3b can be inserted into a lateral receiving compartment 8a of the furniture carcass 2, whereas the door wings 4a, 4b, in a parallel position to one another, can be received within a further receiving compartment 8b. The functionality will be explained with the aid of the door wings 3a, 3b, and the same explanations apply to the other 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 condition, the longitudinal rail 7 is aligned substantially horizontally and parallel to a front edge of the furniture carcass 2.

(10) FIG. 1b shows the item of furniture 1, in which 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, for example, by two or more hinges 10 on a carrier 11, the carrier 11 being insertable into the receiving compartment 8a in a depth direction (Z). In the shown figure, the carrier 11 is located in a transfer position, so that the running carriage 6 can be transferred to and from between the longitudinal rail 7 and the carrier 11.

(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 carriage 6 in or onto the carrier 11. The carrier 11 can be in the form of a longitudinal column, the length of which corresponding to at least half of a height of the door wings 3a, 3b. The two door wings 3a, 3b are hingedly 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.

(12) 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 into the receiving compartment 8a in the depth direction (Z) along at least one guide rail 17, 18 (FIG. 3) of the guide system 5. The at least one guide rail 17, 18 extends transverse to the longitudinal direction (L) of the longitudinal rail 7.

(13) 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 from a first position according to FIG. 1a, in which the door wings 3a, 3b are aligned substantially coplanar to one another, into 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 received within the receiving compartment 8a. In this way, for example, a kitchen 12 as shown in FIGS. 2a, 2b can be entirely covered so as to visually separate the kitchen 12 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 mutually spaced from the sidewall 13a in a parallel relationship. The door wings 3a, 3b, in parallel position to one another, can be inserted between the sidewall 13a and the stationary furniture part 13b.

(14) FIG. 3 shows a perspective view of the guide system 5 in region of 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 fixed to the stationary furniture part 13b, and the longitudinal direction (L) of the longitudinal rail 7 and the longitudinal direction (L2) of the guide rail 17 extend transverse, preferably substantially at a right angle, to one another.

(15) The carrier 11 is configured for movably supporting the door wing 3a, and the door wing 3a can be pivotally supported, for example, via two or more hinges 10 (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.

(16) The carrier 11 is configured to be releasably locked to the longitudinal rail 7 via a receiving device 15. The receiving device 15 is configured to receive the running carriage 6, and the running carriage 6 is configured to run between the longitudinal rail 7 and the receiving device 15. For this purpose, guide grooves 20, 21 may be arranged in the longitudinal rail 7, the guide grooves 20, 21 being aligned flush with corresponding guide grooves 20a, 21a of the receiving device 15 in the transfer position of the receiving device 15. In this way, the running wheels 6a of the running carriage 6 can be displaced between the longitudinal rail 7 and the receiving device 15 without a disturbing abutting edge.

(17) The receiving device 15 is configured to be movably supported relative to the carrier 11 in the longitudinal extension (L1) of the carrier 11. In this way, the receiving device 15 and the carrier 11 can be displaced relative to one another in the longitudinal extension (L1) of the carrier 11, so that the receiving device 15 can be decoupled from undesired torsional movements or sagging movements of the carrier 11 when a mechanical force is exerted to the carrier 11 (for example caused by a force of the door wing 3a or due to an adjustment device for adjusting a position of the door wing 3a). As a result, the guide grooves 20, 21 of the longitudinal rail 7 and the guide grooves 20a, 21a of the receiving device 15, in the transfer position, always remain aligned flush to one another upon a sagging movement or upon a torsional movement of the carrier 11. As a result, a precise displacement of the running carriage 6 between the longitudinal rail 7 and the receiving device 15 can be guaranteed.

(18) For an improved decoupling between the receiving device 15 and the carrier 11, the receiving device 15 includes at least one supporting roller 16a separate from the guiding device 14 of the carrier 11, and the at least one supporting roller 16a is movably supported 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, and 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 16a of the receiving device 15 is movably supported along the second running limb 17b of the guide rail 17.

(19) The carrier 11 and the receiving device 15 are connected in a motionally-coupled manner to one another upon a movement along the guide rail 17 in the depth direction (Z). Preferably, the receiving device 15 and the carrier 11, upon a movement along the guide rail 17 in the depth direction (Z) and upon a movement in a direction opposite the depth direction (Z), are coupled to one another without clearance. For improving the 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.

(20) FIG. 4a shows the item of furniture 1 with the furniture carcass 2, the furniture carcass 2 comprising the stationary furniture part 13b, a cover plate 2a and a sidewall 2b. At least one, preferably two or more, guide rails 17, 18 for displaceably supporting the carrier 11 is or are fixed to the stationary furniture part 13b. The carrier 11 and the receiving device 15 for the running carriage 6 are configured as constructional units which are separate from one another and which are configured to be fixed to one another.

(21) In the shown embodiment, at least one further guide rail 22 for guiding the receiving device 15 is provided, the at least one further guide rail 22 being arranged in a parallel relationship to the guide rails 17, 18 for guiding the carrier 11. The vertically extending, lengthy carrier 11 is movable along the guide rails 17, 18 by a scissor mechanism 24.

(22) FIG. 4b shows the framed region of FIG. 4a in an enlarged view. The carrier 11 includes an interface (mounting member) 23 to allow the receiving device 15 to be fixed (mounted) to the carrier. The interface (mounting member) 23 is configured such that the receiving device 15 and the carrier 11 are fixable to one another by sliding the receiving device 15 in a sliding direction (SR), thus in the depth direction (Z), extending parallel to the at least one guide rail 17, 18. The interface 23 can include at least one guide 23a for guiding the receiving device 15. The guide 23a, in a cross-sectional plane extending perpendicular to the longitudinal extension (L1) of the carrier 11, can be configured substantially U-shaped. The interface 23 includes at least one abutment 25 configured to limit a movement of the receiving device 15 onto the carrier 11 in the sliding direction (SR).

(23) The receiving device 15 can include a plurality of supporting rollers 16a, 16b. The supporting rollers 16a, in a mounted condition of the receiving device 15, are rotatable about a horizontally extending axis and the supporting rollers 16b are rotatable about a vertically extending axis.

(24) FIG. 5a shows the receiving device 15 configured to be fixed to the carrier 11. The carrier 11 has already been pre-mounted to the guide rail 17 via the guiding device 14 having the running wheel 14a. The interface 23 of the carrier 11 can be seen, the carrier 11 having the U-shaped guide 23a for sliding the receiving device 15 onto the carrier 11. A movement of the receiving device 15 in the sliding direction (SR) can be limited by the abutment 25. The guiding device 15 with the running wheels 16a, 16b is displaceably supported along a further guide rail 22 separate from the guide rails 17, 18.

(25) Preferably, the receiving device 15 includes at least one guiding portion 32 configured to be moved along the guide 23a of the interface 23 upon sliding the guiding device 15 in the sliding direction (SR).

(26) FIG. 5b shows the fixed condition of the receiving device 15 on the carrier 11 in a cross-sectional view. The receiving device 15 can be, preferably releasably, secured or locked to the carrier 11 by a locking device 26. The locking device 26 can include at least one lever arm 26a, and it can be preferably provided that the at least one lever arm 26a includes a curved bearing surface 26b and/or at least one locking element 26c, and/or can include at least one spring element 26d, and it can be preferably provided that the at least one spring element 26d is formed by a material elasticity of a plastic portion, and/or can be at least partially arranged in a cavity 11a of the at least one carrier 11, and/or can include at least one pivotable lever arm 26a pressurized by a force of at least one spring element 26d, the lever arm 26a being pivotable against the force of the at least one spring element 26d upon the sliding operation the at least one receiving device 15, and/or can include at least one lever arm 26a and/or at least one locking element 26c, and at least one recess 26e is provided for receiving the at least one lever arm 26a and/or the at least one locking element 26c, and it can be preferably provided that the at least one lever arm 26a and/or the at least one locking element 26c are arranged on the at least one carrier 11 and the at least one recess 26e is arranged on the at least one receiving device 15.

(27) FIG. 6a shows the item of furniture 1 with the furniture carcass 2 in a perspective view. The second door wing 3b is located in a position in which the furniture carcass 2 is covered and the first door wing 3a is hidden for the sake of improved overview. By an ejection device 28, preferably comprising a Touch-Latch function, the door wings 3a, 3b can be ejected from a coplanar position into an angled position to one another.

(28) In the shown embodiment, a mounting portion 27 separate from the carrier 11 is provided. At least two hinges 10 for moving the first door wing 3a are arranged or are configured to be arranged on the mounting portion 27. The mounting portion 27 has a height substantially corresponding to a height of the carrier 11. The mounting portion 27 is configured to be connected to the carrier 11 via at least one fastening device 29.

(29) It can be preferably provided that that in a first step, all hinges 10 provided for moving the door wing 3a are jointly pre-mounted to the mounting portion 27. In a second step, the hinges 10 pre-mounted to the mounting portion 27 are to be connected to the first door wing 3a. In a third step, the mounting portion 27 fixed to the first door wing 3a is to be connected to the carrier 11 via the at least one fastening device 29.

(30) Moreover, the mounting portion 27 fulfils a further function, namely that the mounting portion 27 forms at least one counter-abutment 30 (FIG. 6b) configured to block a movement of the receiving device 15 in a direction opposite the sliding direction (SR). In a mounted condition of the receiving device 15 on the carrier 11, the receiving device 15 is thus received between the abutment 25 of the interface 23 and the mounting portion 27. As a result, a movement of the receiving device 15 within the interface 23 can be prevented or largely restrained.

(31) FIG. 6b shows the encircled region A of FIG. 6a in an enlarged view. The counter-abutment 30 of the mounting portion 27 can be seen, and a movement of the receiving device 15 in a direction opposite the sliding direction (SR) can be prevented by the counter-abutment 30.

(32) FIG. 7a shows the item of furniture 1 with the furniture carcass 2 in a view from the rear.

The longitudinal rail 7 for guiding the door wings 3a, 3b is arranged on the top plate 2a of the furniture carcass 2. The guide rails 17, 18 for displaceably supporting the carrier 11 and the further guide rail 22 separate from the guide rails 17, 18 are fixed to the stationary furniture part 13b. By the scissor mechanism 24, the carrier 11 is movable along the guide rails 17, 18 in a horizontal direction.

(33) FIG. 7b shows the encircled region A of FIG. 7a in an enlarged cross-sectional view, in which the receiving device 15 secured by the locking device 26 can be seen. For reducing a possibly occurring clearance of the receiving device 15 in its mounted condition, at least one clearance compensating element 31 can be provided. By the clearance compensating element 31, a clearance between the at least one receiving device 15 and the at least one carrier 11 in a direction extending parallel to the at least one guide rail 17, 18 can be compensated for. Thereby, it can be provided that the at least one clearance compensating element 31 is arranged on the at least one receiving device 15. In the shown embodiment, at least two clearance compensating elements 31 are arranged on mutually opposing sides of the receiving device 15.

(34) The at least one clearance compensating element 31 can be configured as a spring buffer, and the spring buffer can include a compressible or an elastically deformable plastic material. Alternatively, the clearance compensating element 31 can also include a bearing member pressurized by a force storage member. By the bearing member, a clearance between the receiving device 15 and the carrier 11 can be compensated for.

(35) The method for mounting at least one guide system 5 is characterized by the following, preferably in the indicated order chronologically performed, method steps: the guide rail 17, 18 provided for guiding the at least one carrier 11 is fixed to the stationary furniture part 13b, the at least one carrier 11 is displaceably supported on the at least one guide rail 17, 18 via the at least one guiding device 14, the at least one running carriage 6 is coupled to the at least one door wing 3a, 3b, and the at least one receiving device 15 for receiving the at least one running carriage 6 and the at least one carrier 11 are fixed to one another by sliding in a sliding direction (SR) in a direction extending parallel to the at least one guide rail 17, 18.
