DETAILED DESCRIPTION OF THE INVENTION

(11) A piece of furniture 1 comprises a furniture body 2, on the side walls of which one or more pull-out guides 3 are fixed, which each have at least one movable rail 5. A drawer 4 is held displaceably on two such rails 5, wherein a device 10 or 10 is provided on each rail 5 for fixing the drawer 4 to the rail 5, as can be seen from the bottom view of FIG. 2. A first device 10 with lateral adjustment for fixing the drawer 4 and a second device 10 without lateral adjustment for fixing the drawer 4 to a rail 5 are fixed to a bottom 7 of the drawer 4. Each device 10 and 10 comprises a housing 15, which is fixed to a front panel 6 and/or to the bottom 7 of the drawer 4.

(12) In the detailed view of FIG. 3A, the device 10 is shown during assembly. The housing 15 can be fixed on the underside of the drawer 4 via fastening means 16, wherein a receptacle 20 is provided for inserting a holding part 12. The holding part 12 is attached to the rail 5 of the pull-out guide 3. In this case, the web-shaped holding part 12 can selectively be fixed to the rail 5 by means of an integrally formed tab 9, e.g. by welding, or by means of further components, or the holding part 12 is a part of the rail profile of the rail 5. A device 11 for depth adjustment is provided on the tab 9, which has a non-rotational threaded bolt 14 on which a knurled nut 13 is rotatably supported but is non-displaceable in the axial direction. As a result, by rotating the knurled nut 13, the threaded bolt can be moved in the longitudinal direction of the rail 5 and thus move a stop which predetermines the insertion depth of the holding part 12 in the receptacle 20. Optionally, such a device 11 for depth adjustment can also be dispensed with.

(13) For assembly, the drawer 4 is placed on the two rails 5 of the two pull-out guides 3 and pushed into the closed position. In this case, a respective web-shaped holding part 12 is inserted at opposite sides into the receptacle 20 of the device 10 or 10 and fixed via a clamping mechanism that secures the holding part 12 by clamping and frictional engagement against being pulled out.

(14) FIG. 3B shows the mounted position of the drawer 4. The holding part 12 has been inserted into the receptacle 20 and secured there against being pulled out. The lateral joint pattern can now be adjusted via a device 18 for lateral adjustment. The device 18 for lateral adjustment comprises a knurled nut 19 which, by rotating, causes the housing 15 to be moved laterally in the horizontal direction relative to the receptacle 20 to perform lateral adjustment.

(15) In FIGS. 4A to 4C, the device for depth adjustment is shown in detail. Two angled webs 91 and 92 are provided on a carrier 95, between which the knurled nut 13 is rotatably mounted but axially in a non-displaceable manner. The knurled nut 13 is mounted in this case on a threaded bolt 101, on which a pin 14, which is passed through an opening in the web 92, is provided on one side, and a stop 100 is provided on the other side. The block-shaped stop 100 is guided at a distance from the web 91 by a guide element 90. By rotating the knurled nut 13, the stop 100 can be displaced for depth adjustment in the longitudinal direction of the pull-out guide 3, as can be seen from the different positions of FIGS. 4B and 4C.

(16) FIG. 5 shows the device 10 without the holding part 12. The device 10 comprises a slide 17 which serves to unlock the clamping mechanism. As a result, the drawer 4 can be dismantled again after the assembly when the slide 17 is actuated.

(17) FIG. 6 shows the device 10 without the housing 15, but with the holding part 12, which is clamped in the receptacle 20 in a clamping manner.

(18) The clamping mechanism comprises a clamping lever 25, which is rotatably mounted on a fastening part 23 about a pivot 24. The fastening part 23 is of plate-shaped design and forms a side wall 22 of the receptacle 20, which is arranged opposite the clamping lever 25. The holding part 12 is fixed by clamping in a frictional manner between a contact surface 26 of the clamping lever 25 and the side wall 22 and secured against being pulled out. For this purpose, the pivot 24 is arranged in front of the contact surface 26, as seen in the direction of insertion of the holding part 12, so that the holding part 12, when being inserted into the receptacle 20, first passes a plane perpendicular to the insertion direction which is arranged in the pivot 24, before the holding part 12 touches the contact surface 26. As a result, the clamping lever 25 is formed in a self-locking manner and acts on the holding part 12 in the case of tensile forces, with the clamping lever 25 being pressed with the contact surface 26 even more strongly against the holding part 12.

(19) The clamping lever 25 is designed as a two-armed lever, wherein the contact surface 26 is formed on one arm for the clamping fixing of the holding part 12, and means for unlocking the clamping lever 25 act on a second arm 27. The clamping lever 25 is designed in the form of an angle and is pretensioned into the clamping position by an integrally formed spring 30. In this case, the spring 30 is designed as a leaf spring and rests on the housing 15. The means for unlocking comprise a bolt 28, which is slidably formed in a wedge-shaped gap 29 between the arm 27 and the fastening part 23. When the bolt 28 is moved along fastening part 23 to the end of the arm 27, the arm 27 is moved by the wedge-shaped formation of the gap 29, and the clamping lever 25 rotates so that the contact surface 26 is disengaged from the holding part 12. As a result, the holding part 12 can be easily pulled out after the clamping lever 25 has been turned. The bolt 28 is guided along a side wall of the fastening part 23.

(20) The clamping lever 25 is in this case made from a bent metal plate which engages around a portion of the plate-shaped fastening part 23 in a U-shaped manner. The bottom of the U is formed in this case on the contact surface so that a line-shaped contact surface 26 rests against the holding part.

(21) FIG. 7 shows an exploded view of the device 10 with the housing 15. A slot-shaped receptacle 33 is provided on the housing 15, on which the fastening part 23 is held displaceably with the clamping lever 25. In this case, a head section on the pivot 24 is guided in a groove-shaped guide 34. The fastening part 23 can be guided in the housing 15 via further or other surfaces. Furthermore, the slide 17 is shown, which is designed as a cap-shaped part and holds the bolt 18 between two arms 31. The bolt 28 can be displaced along the wedge-shaped gap 29 by means of a movement of the slide 17. The slide 17 is pretensioned in this case by a spring 32 into an initial position, in which the bolt 28 does not unlock the clamping lever 25. Only by shifting the slide 17 against the force of the spring 32 unlocking of the clamping lever 25 is effected.

(22) Furthermore, the device 18 for lateral adjustment is shown, in which a threaded bolt 40 engages in a threaded bore 41. A knurled nut 19 is fixed on the threaded bolt 40, wherein one edge of the knurled nut engages in a U-shaped receptacle 35 on the fastening part 23. By rotating the knurled nut 19, the fastening part 23 can thus be displaced relative to the housing 15 in the longitudinal direction of the threaded bolt 40, i.e. in a plane parallel to the front panel 6 of the drawer 4.

(23) FIGS. 8A to 8C show the device 10 with the housing 15 in detail. The plate-shaped fastening part 23 is slidably mounted within the receptacle 33 of the housing 15 and in turn itself supports the clamping lever 25 via the pivot 24. The slide 17 engages around the housing 15 in a U-shaped manner and is guided linearly in order to pivot the clamping lever 25 for an unlocking operation by displacement.

(24) In FIG. 9, the device 10 is shown in an unlocking position, in which the slide 17 has been pushed onto the housing 15. The bolt 28 thus moves the clamping lever 25 so that the contact surface 26 moves slightly away from the opposing side wall 22 so that a holding part 12, which is arranged between the side wall 22 and the contact surface 26, can be pulled out of the receptacle 20. The movement of the contact surface 26 can be in a range between 0.02 to 4 mm, in particular 0.4 mm to 2 mm.

(25) FIG. 10 shows the device 10, which is designed like the device 10, but without the device 18 for lateral adjustment. In this respect, the knurled nut 19 and the threaded bolt 40 are missing. Apart from that, the device 10 can be designed identically or mirror-symmetrically to the device 10. In this case, the fastening part 23 can be movably mounted in the housing 15, so that the device 10 forms a loose bearing, whereas on the opposite side a fixed bearing is provided which positions the drawer 4 within the furniture body 2 in the horizontal lateral direction.

(26) In the exemplary embodiment shown, both the clamping lever 25 and the fastening part 23 consist of metal, in particular of a steel sheet. As a result, particularly high holding forces can be applied to the likewise metallic holding part 12.

(27) In the exemplary embodiment shown, the clamping lever 25 is mounted with two arms around a pivot 24. It is also possible to form the clamping lever 25 with only one arm. Furthermore, other means for unlocking the clamping lever 25 can also be provided instead of the slide 17, for example a pivotable unlocking lever.

(28) It is understood that the clamping lever 25 is merely representative of an example for a clamping element. Another clamping element, e.g. a clamping shoe or a clamping roller, is also possible for the use according to the invention.
