[0059] FIG. 5 the upper and lower spacer devices 7, 8 of FIG. 2 in a preferred embodiment provided for guiding a door 11 with only one door element 111;

[0060] FIG. 6a the upper spacer device 7 of FIG. 5, which is held by the upper guide rail 15;

[0061] FIG. 6b the lower spacer device 8 of FIG. 5, which is held by the lower guide rail 16;

[0062] FIG. 7 a part of the displacement device 10 of FIG. 2 with the upper spacer device 7 in a preferred embodiment; and

[0063] FIG. 8 the upper spacer device 7 of FIG. 7 in exploded view.

[0064] FIG. 1 shows an inventive functional entity or a piece of furniture 1 in the embodiment of a wardrobe in which a door compartment 18 is integrated on each side. The piece of furniture 1 comprises side walls 1A, an upper board 1B, a lower board 1C and partitions 1D, each of which together with an associated side wall 1A delimits a door compartment 18. In each door compartment 18 an inventive displacement device 10 with a mounting profile 14 is arranged, which is automatically displaceable within the door compartment 18 by manual operation or by means of a drive device (see FIG. 3, drive device 2). Doors 11 are held by the mounting profiles 14 of the sliding devices 10, which are retracted into or moved out of the associated door compartment 18 when the mounting profile 14 is moved. When the door 11 leaves the respective door compartment 18, the mounting profile 14 is displaced along a running axis x from the rear side 181 of the door compartment 18 to an entrance opening 180 of the door compartment 18.

[0065] In the first door compartment 18, a foldable sliding door 11 is held, which comprises a first and a second door element 111, 112, which are hinged to each other and can be folded towards each other. The door 11 held in the second door compartment 18 by the mounting profile 14 inside the second door compartment 10 comprises only one door element 111. The first door element 111 comprises an inner side 1111 and an outer side 1112. The second door element 112 comprises an inner side 1121 and an outer side 1122 (see FIG. 4b).

[0066] In FIG. 1, the foldable sliding door 11 is fully extended from the first door compartment 10 and fully unfolded so that the door elements 111, 112 are aligned in one plane and only their outer sides 1112, 1122 are visible. The door elements 111, 112 of the foldable sliding door 11 and the door element 111 of the one-piece door 11 are of equal size. The foldable sliding door 11 shown in the closed position covers therefore two thirds of the wardrobe opening 100.

[0067] The rear-sided edge 1115 of the first door element 111 of the foldable sliding door 11, which is trailing when the sliding door 11 is moved out, is connected by mounting hinges 131 to the mounting profile 14 symbolically shown by a dashed line.

[0068] The leading front-sided edge 1116 of the first door element 111 is connected by door hinges 132 to the trailing rear-sided edge 1125 of the second door element 112, whose leading front-sided edge is connected at the top to a front carriage 5F. The front carriage 5F is guided in a support rail 17, which comprises curved sections and support rail sections 171 on both sides, which extend into the door compartments 18. When entering the door compartment 18 and when travelling along the support rail 17, the front carriage 5F moves forward within an associated path, whereby the change of direction takes place within the curved section.

[0069] Inventive functional entities 1 comprise at least one spacer device 7, 8. FIG. 1 shows schematically that in this preferred embodiment of the functional entity 1 each of the displacement devices 10 comprises an upper spacer device 7 and a lower spacer device 8, which allow to precisely guide and hold the doors 11 and the door elements 111, 112, respectively.

[0070] FIG. 2 shows the displacement device 10 arranged in the first door compartment 18 of the functional entity 1 of FIG. 1 with the foldable sliding door 11, the door elements 111, 112 of which are shown cut away to show the spacer devices 7 and 8. The door elements 111, 112, which are connected to each other by door hinges 132 shown schematically, are aligned parallel to each other and can be pushed into the door compartment 18 in this alignment.

[0071] The mounting profile 14 is connected to the first door element 111 by mounting hinges 131 and is held in a vertical position by a holding device 4 (shown symbolically by dotted lines). The holding device 4 can be of any embodiment, for example a scissors cross, a parallelogram or preferably a device with holding cords as shown in FIG. 3.

[0072] The mounting profile 14 is connected at the upper end to an upper guide carriage 5, which is guided in an upper guide rail 15, and at the lower end to a lower guide carriage 6, which is guided in a lower guide rail 16. The upper guide carriage 5 comprises support rollers 591 and guide rollers 592 and, in addition to the guide function, also comprises a support function. The lower guide carriage 6 comprises guide rollers 692, which are guided in the lower guide rail 16 (see FIG. 3).

[0073] The upper guide carriage 5 and the lower guide carriage 6 are located directly in front of the entrance opening 180 of the door compartment 18. The carriage body 51 of the upper guide carriage 5 rests against a buffer device or damper device 3 mounted in the upper guide rail 15.

[0074] The upper guide rail 15 holds front-sided an upper spacer device 7 and the lower guide rail 16 holds front-sided a lower spacer device 8, each comprising a device body 71, 81. FIG. 2 shows that the spacer devices 7, 8 are enclosed between the two parallel door elements 111, 112.

[0075] On the side facing the first door element 111, the upper and lower spacer devices 7, 8 each comprise at least one first spacer roller 791, 891 and at least one first device magnet member 771, 871. On the side facing the second door element 112, the upper and lower spacer devices 7, 8 each comprise at least one second spacer roller 792, 892 and at least one second device magnet member 772, 872.

[0076] The first spacer rollers 791, 891 keep the first door element 111 at a distance and can roll along its inner side 1111. The second spacer rollers 792, 892 keep the second door element 112 at a distance and can roll on its inner side 1121. The two door elements 111, 112 can therefore not hit the device body 71, 81 of the spacer devices 7, 8 or the guide rails 15, 16.

[0077] The first device magnet members 771, 871 interact with first door magnet members 751, 851 which are connected to the first door element 111 (see FIG. 5). The second device magnet members 772, 872 interact with second door magnet members 752, 852 which are connected to the second door element 112. The first and the second device magnet members 771, 871; 772, 872 and the first and the second door magnet members 751, 851; 752, 852 interact magnetically and exert forces on each other which pull the two door elements 111, 112 against the spacer devices 7, 8. Therefore, the first and/or the second spacer rollers 791, 891; 792, 892 are always in contact with the inner sides 1111, 1121 of the first and/or second door element 111, 112 and preferably run there on the door magnet member 751, 851; 752, 852 or a cover 76, 86 provided on the door magnet member 751, 851; 752, 852, which are preferably designed as running surfaces. As mentioned, at least one of the corresponding device magnet members 771, 871; 772, 872 and the door magnet members 751, 851; 752, 852 is formed as a permanent magnet, so that a permanent magnet part cooperates with a ferromagnetic part. In preferred embodiments, the device magnet members 771, 871; 772, 872 and the door magnet members 751, 851; 752, 852 may be permanent magnets.

[0078] When moving into or out of the door compartment 18, the two door elements 111, 112 are therefore guided and held by the two spacer devices 7, 8 without play or substantially without play. In particular, even after the two door elements 111, 112 have entered the door compartment 18, their end faces 1116, 1125, which are connected to each other by the door hinges 132, are held stably by the spacer devices 7, 8. The door elements 111, 112 are therefore kept stable during travel and also when stationary and can neither strike inwards against the guide rails 15, 16 nor outwards against a side wall 1A or a separation wall 1D (see FIG. 1).

[0079] The displacement device 10 can be used to hold a single-part or multi-part door 11. With reference to FIG. 2, the use of the displacement device 10 in combination with a door with two door elements 111, 112 was described. The inventive spacer devices 7, 8, on the other hand, can also be used to guide only one door element 111 of a single-part door 11 or of the first door element 111 of a multi-part door 11. FIG. 5 shows a part of a displacement device 10 which is provided for guiding only one door element 111.

[0080] FIG. 3 shows the displacement device 10 of FIG. 2 with a preferred holding device 4 and an optionally provided drive device 2 from the other side.

[0081] The holding device 4 comprises a first front-sided cable connection device 84, a first lower reel assembly 431 disposed at the lower end of the mounting profile 14, a first upper reel assembly 411 disposed at the upper end of the mounting profile 14, and a first rear-sided cable connection device 44 disposed at the rear-sided end of the upper guide rail 15, and a first holding cable 421 connected at a first end to the first front-sided cable connection device 84, routed counterclockwise around the first lower reel assembly 431 and clockwise around the first upper reel assembly 411, and connected at a second end to the first rear-sided cable connection device 44.

[0082] Furthermore, the holding device 4 comprises a second front-sided cable connection device 74, a second upper reel assembly 412 disposed at the upper end of the mounting profile 14, a second lower reel assembly 432 disposed at the lower end of the mounting profile 14, and a second rear-sided cable connection device 45 disposed at the rear-sided end of the lower guide rail 16, and a second holding cable 422 connected at a first end to the second front-sided cable connection device 74, routed clockwise around the second upper reel assembly 412 and counterclockwise around the second lower reel assembly 432, and connected at a second end to the second rear-sided cable connection device 45.

[0083] The preferably adjustable first front-sided cable connection device 84, by means of which the first pull cord 421 can be tensioned in order to vertically align the mounting profile 14, is integrated into the lower spacer device 8. The second front-sided cable connection device 74 is integrated in the upper spacer device 7. The two rear cable connection devices 44, 45 preferably each comprise an entry pulley through which the respective holding cable 421, 422 can be inserted into a housing. Preferably, a tension spring is provided in the second rear-sided cable connection device 45, via which a constant tensile force can be transmitted to the second holding cable 422.

[0084] Hence, in the inventive holding device 4, preferably one of the holding cables 421, 422, in this embodiment the second holding cable 422, is always held resiliently. The first holding cable 421, on the other hand, is held inelastically or firmly by the first front-sided cable connection device 84 and the first rear-sided cable connection device 44 after installation. The first front-sided cable connection device 84 is adjustable to tighten the first holding cable 421 and to align the mounting profile 14 vertically.

[0085] Furthermore, the displacement device 10 optionally comprises a drive device 2 by means of which the door 11 can be automatically driven out of the door compartment 18. The exemplarily shown and preferably used drive device 2 comprises a drive unit 21 with a drive element and a pulley connected thereto, on which a pull cord 22 is wound. The drive element is, for example, a spiral spring or a helical spring, which is tensioned or released when the pulley rotates. The pull cord 22 can therefore be pulled off the pulley by force and is automatically wound back onto the pulley as it rotates back.

[0086] The pull cord 22 is guided via a first deflection roller 23, which is rotatably mounted on a deflection unit 230, and a second deflection roller 24 to a pull cord connection 72, which is arranged on the upper spacer device 7. The deflection unit 230 can be moved along the mounting profile 14 and can optionally be fixed. By moving the deflection unit 230, a desired tension can be applied to the pull cord 22.

[0087] In FIG. 3, the mounting profile 14 has been moved almost to the rear side 181 of the door compartment 18, therefore the pull cord 22 has been extended further and the drive element has been tensioned. As soon as the pull cord 22 is released again, the pulley is turned back by the tensioned drive element.

[0088] By connecting the drive device 2 to the mounting profile 14 or the guide carriage 5, it is no longer necessary to mount the drive device 2 on a rear wall, a separation wall 1D or a side wall 1A of the functional entity 1. It is particularly advantageous that the displacement device 10 with the holding device 4 and the drive device 2 can be installed in differently dimensioned door compartments 18 without modification. Only the lengths of the holding cables 421, 422 and of the pull cord 22 need to be adjusted accordingly.

[0089] It is further shown that the spacer devices 7, 8 are provided with rotatable locking levers 73, 83, by means of which the mounting profile 14, which is displaced towards the opening 180 of the door compartment 18, can be locked in order to carry out maintenance work or adjustments.

[0090] FIG. 4a shows the upper spacer device 7 of FIG. 2 with the device magnet members 771, 772 detached from the device body 71 and a sectional view through the two door elements 111, 112, which shows the door magnet members 751, 752 sunk into the door elements 111, 112 and the covers 76 shown in sectional view lying on the door magnet members 751, 752. The device body 71 of the spacer device 7 comprises a mounting beam 711 on the upper side, which is inserted into a mounting channel of the upper guide rail 15 and locked by locking screws 712. The upper guide rail 15 is symbolically shown with dashed lines.

[0091] If the upper and lower guide rails 15, 16 comprise an identical or at least functionally identical holding channel, the upper spacer device 7 can be turned by 180 and used as a lower spacer device 8, for example when using a scissor cross as holding device 4. The spacer device 7 can also be connected to a device magnet member 771 on one side only, if only one door element 111 is to be moved into the door compartment 118.

[0092] On both sides, the device body 71 comprises in this preferred embodiment threaded holes into which connection screws 78 can be screwed to mount the first device magnet member 771 on one side and the second device magnet member 772 on the other side of the device body 71. Preferably, an elastic element 781 is provided between the connection screws 78 and the device magnet members 771, 772, which transmits the compressive force of the connection screws 78 elastically to the device magnet members 771, 772. However, the device magnet members 771, 772 can also be connected to the device body 71 in a force-fitting or form-fitting manner in other ways. For example, the device magnet members 771, 772 can be inserted into recesses in the device body 71, for example glued and/or encapsulated or only held magnetically. If the device body 71 is made of a ferromagnetic material, the device magnet members 771, 772 are automatically held in the recesses of the device body 71.

[0093] The first plate-shaped door magnet member 751 is arranged inside a door recess 1110 on the inner side 1111 of the first door element 111 and fastened by means of a mounting screw 7511. A cover or cap 76 is inserted into the door recess 1110, the outer side of which lies in a plane with the inner side 1111 of the first door element 111. The second plate-shaped door magnet member 752 is located inside a door recess 1120 on the inner side 1121 of the second door element 112 and fastened by means of a mounting screw 7521. A cover or cap 76 is inserted into the door recess 1120, the outer side of which lies in a plane with the inner side 1121 of the second door element 112.

[0094] The cover 76 can for example be made of metal, plastic or wood. Alternatively, the cover 76, for example a foil or a plate, can cover the entire inner side 1111, 1121 of the door elements 111, 112. In preferred embodiments, the cover 76 therefore forms a coating on the door elements 111, 112.

[0095] FIG. 4b shows the upper spacer device 7 of FIG. 4a after mounting the device magnet members 771, 772. Instead of the upper guide rail 15, the upper guide carriage 5 with the support rollers 591 and the guide rollers 592 is shown in this illustration. It can be seen that the door elements 111, 112 shown in sectional view are held at a distance from the device body 71 by the spacer rollers 791, 792 and are simultaneously pulled against the spacer rollers 791, 792 by the device magnet members 771, 772. The door 11 is thus held precisely both when it is moved and when it is stationary.

[0096] FIG. 5 shows the upper and lower spacer devices 7, 8 of FIG. 2 in a preferred embodiment for guiding a door 11 with only one door element 111, from which a centre piece has been cut out. The spacer devices 7, 8 are consequently only provided on one side with a spacer roller 791, 891 and a device magnet member 771, 871. The upper guide rail 15 and the lower guide rail 16, which hold the upper and lower spacer devices 7, 8 front-sided, are shown shortened. Door recesses 1110 are provided on the inner side 1111 of the door element 111, which extend over almost the entire width of the door element 111. A portion of the plate-shaped upper door magnet members 751 has been cut away to show the door recess 1110. The plate-shaped door magnet members 751, 752 comprise holes 7510, 8510 into which mounting screws 7511 are inserted. The covers 76, 86 extend across the entire length of the door recesses 1110.

[0097] FIG. 6a shows the upper spacer device 7 of FIG. 5, which is held by the upper guide rail 15. The upper guide rail 15 comprises a mounting channel 150 on the lower side, into which a mounting beam 711 connected to the device body 71 of the upper spacer device 7 is inserted. The inserted mounting beam 711 is locked or tensioned by means of locking screws 712. Above the mounting channel 150, the upper guide rail 15 comprises a cross-section within which the upper guide carriage 5 can be moved up to a buffer device or damper device 3.

[0098] In this embodiment, the device magnet member 771, which is offset from the spacer roller 791, is plate-shaped and preferably held in a recess 710 of the device body 71 and fixed with a connection screw 78. The device magnet members 771, 772; 871, 872, on the other hand, can comprise any shape and, for example, be cylindrical, pill-shaped, tablet-shaped, plate-shaped and have a round, rectangular, square or polygonal cross-section. The contactless cooperation of the door magnet members 751, 752; 851, 852 and the device magnet members 771, 772; 871, 872 allows the latter to be connected to the device body 71, 81 at a location where no further function of the spacer device 7, 8 is impaired.

[0099] The spacer roller 791 is rotatably mounted in a roller holder 715 by means of a bearing shaft 790. The roller holder 715 is preferably held form-fittingly in a bearing chamber 716 of the device body 71 and is fixed by means of a mounting screw or adjustment screw 713. Preferably, the roller holder 715 is slidably mounted and can be positioned as desired by means of the adjustment screw 713.

[0100] It should be noted that in this preferred embodiment the spacer roller 791 projects beyond the device body 71 not only on the side of the associated device magnet members 78 but also front-sided. The door element 111 is therefore not only guided during the axial displacement within the door compartment 18 but also during the pivoting movement at the exit of the door compartment 18 and kept at a distance from the device body 71.

[0101] FIG. 6b shows the lower spacer device 8 of FIG. 5, which is held by the lower guide rail 16. The lower guide rail 16 also comprises a mounting channel 160 in which a mounting beam 811 connected to the device body 81 of the lower spacer device 8 is held. The lower roller holder 815 is also slidably mounted and comprises a buffer body 8153 which holds a buffer element 8154 and which is guided through an opening in the device body 81.

[0102] The lower and upper spacer devices 7, 8 are therefore basically interchangeable. Furthermore, the spacer devices 7, 8 can advantageously comprise further functional elements, such as preferably adjustable buffer devices, damping devices, stop device, locking lever 83, rope connection devices 84.

[0103] FIG. 7 shows a part of the displacement device 10 of FIG. 2 with the upper spacer device 7, which in this preferred embodiment comprises two spacer rollers 791, 792. The first spacer roller 791 is held by a roller holder 715 which is slidably mounted within a bearing chamber 716 of the device body 71 and is selectively slidable by means of an adjustment screw 713. The guide carriage 5 guided within the upper guide rail 15 is advanced with the carriage body 51 to the damping device 3.

[0104] FIG. 8 shows an exploded view of the upper spacer device 7 of FIG. 7. The roller holder 715 comprises guide ribs 7151 on the lower side and the upper side, which are guided in corresponding guide tracks 718 of the bearing chamber 716. The roller holder 715 is also preferably integrally connected to a buffer piston 7153, on the front side of which a buffer element 7154 is held. The spacer roller 791 and the buffer element 7154 are therefore preferably firmly coupled to each other, so that when adjusting the end stop of the upper guide carriage 5, the first spacer roller 791 is simultaneously optimally positioned and does not have to be positioned separately. In addition, the roller holder 715 comprises a holding flange 7152, by means of which the head of the adjustment screw 713 is held rotatably but not axially displaceably within a screw chamber. Furthermore, the roller holder 715 comprises a tool opening 7150 through which a screwdriver can be inserted into the screw chamber to turn the adjustment screw 713.

[0105] The device body 71 comprises a bearing chamber 716 into which the roller holder 715 can be inserted. A transfer opening 717 is provided on the rear wall of the bearing chamber 716, through which the buffer piston 7153 with the buffer element 7154 is guided. A threaded bore 719 is also provided on the rear wall of the bearing chamber 716, into which the adjustment screw 713 is screwed. By turning the adjustment screw 713, the roller holder 715 with the first spacer roller 791 and the buffer element 7154 can therefore be moved relative to the device body 71.
