DETAILED DESCRIPTION OF THE INVENTION

(7) An item of furniture 1 comprises a furniture body 2, on the side walls of which one or more pullout guides 3 are fixed, which have at least one movable rail 5. A drawer 4 is held so it is movable on two such rails 5, wherein a device 10 for fixing the drawer 4 on the rail 5 is provided for this purpose on each rail 5, as is recognizable from the bottom view of FIG. 2. A first device 10 having lateral adjustment for fixing the drawer and a second device 10 without lateral adjustment for fixing the drawer are fixed on a rail 5 on a bottom 7 of the drawer 4. Each device 10 comprises a housing 15 in this case, which is fixed on a front panel 6 and/or the bottom 7 of the drawer 4.

(8) In the detail view of FIG. 2, the device 10 is shown during the installation. The housing 15 can be fixed via fastening means 16 on the lower side of the drawer 4, wherein a receptacle 20 is provided for inserting a holding part 12. The holding part 12 is held on the rail 5 of the pullout guide 3. In this case, the web-shaped holding part 12 can optionally be fixed via an integrally formed tab 9 on the rail 5 or can be formed as a separate component which is fixed on the rail 5 or is fixed on the rail 5 via further components, or the holding part 12 is a part of the rail profile of the rail 5. A unit 11 for depth adjustment is provided on the tab 9, which has a rotationally-fixed, but axially-displaceable mounted threaded bolt 14, on which a knurled nut 13 is mounted so it is rotatable, but axially immovable. The threaded bolt 14 can thus be moved in the longitudinal direction of the rail 5 by rotating the knurled nut 13 and can therefore move a stop which specifies the maximum insertion depth of the holding part 12 into the receptacle 20. Such a unit 11 for depth adjustment can optionally also be omitted.

(9) For the installation, the drawer 4 is placed on the two rails 5 of the two pullout guides 3 and pushed into the closed position. In this case, a web-shaped holding part 12 is inserted into the receptacle 20 of the device 10 or 10, respectively, on each of the opposing sides and fixed via a clamping mechanism, which secures the holding part 12 in a clamping and friction-locked manner against pulling out. A lateral front panel alignment can be adapted via a unit 18 for lateral adjustment. The unit 18 for lateral adjustment comprises a knurled nut 19, which causes the receptacle 20 to be moved laterally in the horizontal direction in relation to the housing 15 by rotation, to perform a lateral adjustment.

(10) FIGS. 3 and 4 show the device 10, on which a receptacle 20 for receiving the holding part 12 is formed. The device 10 comprises a plate-shaped fastening part 23, on which the clamping lever 25 is mounted so it is rotatable about a rotational axis 24 and is pre-tensioned by a spring 30 in the locked position. The clamping lever 25 can also be fastened differently or embodied in one piece with the fastening plate. If the clamping lever is not mounted so it is rotatable, the clamping lever can fulfill its function by bending. The clamping lever 25 is produced here from a bent metal plate, which encloses a section of the plate-shaped fastening part 23 in a U shape. A contact surface 26, which presses as a linear contact against the holding part 12, is formed in this case on the bottom of the U.

(11) Furthermore, a modified slide 27 is provided on the fastening part 23, which has a different shape than the slide 17 in FIG. 2, but is also used for unlocking the clamping lever 25. For this purpose, a holder 36 is provided on the slide 27, to actuate the means for unlocking 28, which comprise a traction element which engages with a section 37 in the holder 36. The traction element is arranged on the opposite side with a section 48 in a wedge-shaped gap 29 between the clamping lever 25 and the fastening part 23. By pulling the traction element, the clamping lever 25 can be pivoted against the force of a spring into the unlocking position. Oblong holes 38, which are penetrated by pins 39, are provided on the slide 27 to guide the slide 27 accordingly.

(12) FIG. 5A shows the clamping lever 25 in the locked position, but without holding part 12. The slide 27 has spring elements 42, which are supported against a section of the means for unlocking 28 and thus hold the slide 27 in its starting position. To unlock the clamping lever 25, the slide 27 is moved against the force of the spring elements 42 along the oblong holes 38 until the position shown in FIG. 5B is reached. By displacing the slide 27, the traction element of the means 28 for unlocking the clamping lever 25 is moved, which is moved along the gap 29 and thus has pivoted the clamping lever 25 counterclockwise. The gap between the contact region 26 of the clamping lever 25 and the opposing side wall 22 is thus enlarged, so that the holding part 12 can be pulled out of the receptacle 20 nondestructively.

(13) The plate-shaped fastening part 23 is inserted into a receptacle 33 on the housing 15. Furthermore, a recess 21 is formed on the housing 15 in the region of the receptacle 20. The fastening part 23 has a receptacle 35 for inserting an edge section of the knurled nut 19, so that the fastening part 23 can be displaced in relation to the housing 15 for a lateral adjustment.

(14) In the illustrated exemplary embodiment, both the clamping lever 25 and also the fastening part 23 consist of metal, in particular a steel plate. Particularly high holding forces can thus be applied to the holding part 12, which is also metallic.
