[0034]
[0035] 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 or 10, respectively, 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
[0036] In the detail view of
[0037] 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 12 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.
[0038]
[0039]
[0040]
[0041] The clamping mechanism comprises a clamping lever 25, which is mounted on a fastening part 23 so it is rotatable about a bolt-shaped rotational axis 24. The fastening part 23 is plate-shaped and forms a side wall 22 of the receptacle 20, which is arranged opposite to the clamping lever 25. The holding part 12 is fixed by clamping in a friction-locked manner between a contact surface 26 of the clamping lever 25 and the side wall 22 and secured against pulling out. For this purpose, the rotational axis 24 is arranged in front of the contact surface 26 viewed in the insertion direction of the holding part 12, so that the holding part 12, upon insertion into the receptacle 20, firstly passes a plane perpendicular to the insertion direction in which the rotational axis 24 is arranged, before the holding part 12 touches the contact surface 26. The clamping lever 25 is thus made self-locking and in the event of traction forces on the holding part 12, the clamping lever 25 having the surface 26 is pressed even more strongly against the holding part 12.
[0042] The clamping lever 25 is designed as a two-armed lever, wherein the contact surface 26 for the clamping fixing of the holding part 12 is formed on one arm and means for unlocking the clamping lever 25 engage on a second arm. The clamping lever 25 is formed angled in this case and is pre-tensioned by an integrally formed spring 30 in the clamping position. The spring 30 is designed in this case as a leaf spring and is supported on the housing 15. The means for unlocking comprise a bolt 28, which is formed so it is displaceable in a wedge-shaped gap 29 between the arm 27 and the fastening part 23. If the bolt 28 is pushed toward 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 such that the contact surface 26 disengages from the holding part 12. The holding part 12 can thus be pulled out easily after rotation of the clamping lever 25. The bolt 28 is guided in this case along a side wall of the fastening part 23.
[0043] The clamping lever 25 is produced in this case from a bent metal plate, which encloses a section of the plate-shaped fastening part 23 in a U shape. The bottom of the U is formed on the contact surface 26 in this case, so that a linear contact surface 26 presses against the holding part 12.
[0044]
[0045] Furthermore, the unit 18 for lateral adjustment is shown, in which a threaded bolt 40 engages in a threaded borehole 41. A knurled nut 19 is fixed on the threaded bolt 40, wherein an 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 therefore be displaced in relation 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. During the lateral adjustment, the slide 17 is pivoted, since it is guided on one side on the housing 15 and on the other side via the bolt 28 on fastening part 23.
[0046]
[0047]
[0048]
[0049] 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.
[0050]
[0051] Furthermore, a modified slide 127 is provided on the fastening part 123, which is used for unlocking the clamping lever 125. For this purpose, a holder 136 is provided on the slide 127, to receive a section 137 of a wire bow, which is used for unlocking the clamping lever 125. The wire bow is arranged on the opposite side with a section 148 in a wedge-shaped gap 129 between the clamping lever 125 and the fastening part 123. By pulling the traction element of the means 128 for unlocking the clamping lever 125, the clamping lever 125 can be moved against the force of a spring into the unlocked position. Oblong holes 138 are provided on the slide 127, which are penetrated by pins 139 to guide the slide 127 accordingly.
[0052]
[0053] The plate-shaped fastening part 123 is inserted into a receptacle 133 on the housing 115. Furthermore, an opening 121 is formed in the region of the receptacle 120 on the housing 115. The fastening part 123 has a receptacle 135 for insertion of an edge section of the knurled nut 119, so that the fastening part 123 can be displaced in relation to the housing 115 for a lateral adjustment.
[0054]
[0055] The clamping lever 125 comprises an actuating arm 157, which can cooperate with the slide 151.
[0056] Furthermore, a receptacle 131 for inserting a spring 130, which is designed as a leaf spring and acts on the clamping lever 125 to pre-tension it in the locked position, is provided on the plate-shaped fastening part 123.
[0057]
[0058]
[0059] For the installation of the movable furniture part, the web-shaped holding part 212 is inserted into the receptacle 220 of the device 210 and fixed via a clamping mechanism, which secures the holding part 212 in a clamped and friction-locked manner against pulling out.
[0060] Outside the receptacle 220, in addition to the holding part 12, a linearly movable web 228 is provided, which is connected to a slide 217, which is pre-tensioned via a spring 232 in a starting position. The spring 232 is supported in this case on one side on the slide 217 and on the other side on a stop 233 on the tab 209.
[0061] As shown in
[0062] The clamping lever 225 is produced from a bent metal plate, which encloses a section of the plate-shaped fastening part 223 in a U shape. A contact surface 226 is formed in this case on the bottom of the U, which presses as a linear contact surface 226 against the holding part 212.
[0063] To disengage the clamping lever 225, the holding web 228 can be inserted via the slide 217 against the force of the spring 232 into the receptacle 220, whereby the clamping lever 225 in
[0064]
[0065] Optionally, in the devices 210 or 210, a unit can be provided for lateral, height, and depth adjustment to adapt the front panel alignment. The unit for lateral adjustment can have a knurled nut, for example, which engages with an edge in a receptacle 235 and causes a housing to be moved laterally in relation to the receptacle 220 in the horizontal direction by rotating, as was already described above.
[0066]
[0067] A holding part 312, which is formed as strip-shaped and can also consist of a steel plate, can be fixed on the receptacle 320. The holding part 312 is fixed on a movable slide rail 305 of a pullout guide 301, for example, by welding. The pullout guide 301 comprises a stationary guide rail 302, which can be fixed on a furniture body. The holding part 312 can also be fixed, however, on another furniture part, for example, a sliding door or on a stationary furniture body.
[0068] For the installation of the web-shaped holding part 312, it is inserted into the receptacle 320 and fixed via the clamping mechanism having the two clamping levers 325, which secure the holding part 312 in a clamped and friction-locked manner against pulling out (
[0069] For unlocking of the clamping mechanism, an unlocking element 328 is provided, which can easily move the clamping levers 325 formed as flaps in the opening direction. For this purpose, the unlocking element 328 is mounted so it is pivotable on the fastening part 323, as is recognizable from
[0070] In all exemplary embodiments, only one installation direction is shown. The device can be designed with further clamping mechanisms so that the movable furniture part can be displaced in the desired depth, height, and/or laterally, and then fixed.
