Description

Drawer

The present invention relates to a drawer with a base, two side frames and a rear wall connecting the side frames, at least one housing of an adjusting device being fixed to the rear wall.

DE 10 2014 007 828 A1 discloses a device for aligning a base of a drawer, in which a recess is made in the base, into which a receiving housing is inserted. In the receiving housing, an adjusting screw and an adjusting body are provided in order to align the bottom of the drawer relative to a guide rail of a pull-out slide. Aligning the floor to adjust the inclination is necessary, but making a recess in the floor leads to a weakening of the material, which can lead to problems with high weight loads.

It is therefore the object of the present invention to create a drawer that has a simply constructed adjusting device that can accommodate high loads.

This object is achieved with a drawer with the features of claims 1.

In the drawer according to the invention an adjusting device is provided on a rear wall, which has at least one housing and at least one re relative to the housing movable pressure rod, which can be supported directly or via a stamp on a rail of a pull-out guide. As a result, the inclination can be adjusted by moving the push rod relative to the housing, the weight loads being able to be diverted to the running rail of a pull-out guide via the housing fixed to the rear wall and the push rod. This avoids the provision of recesses on the floor and enables the adjustment device to be arranged on a rear region of the rear wall which is not visible in the assembled position.

The adjusting device preferably comprises a rotating part with an eccentric which is rotatably mounted on the housing. As a result, the pressure rod can be continuously adjusted relative to the housing, with the eccentric can be moved by hand either using a tool or an integrally formed actuating section.

A stamp is preferably attached to an underside of the pressure rod which has a receiving section, preferably an opening, into which a hook protruding from the rail can be inserted. As a result, the stamp can be fixedly mounted on the running rail, so that the distance between the stamp and the housing can be adjusted during an adjustment process. For a stable connection, the stamp can be held on a guide in a displaceable manner. The guide can optionally be formed on a separate guide component or integrally with the housing. If the guide is formed on the housing, this can have a guide channel which is open downward in the direction of the running rail and in which the stamp is held displaceably.

According to a first variant, the rear wall and / or side frame is made from a bent sheet steel or extruded aluminum profile. The bent steel sheet can have a bent edge in the upper wall or frame area, which is preferably U-shaped in cross section, the housing being fixed in or on the bent edge. Additionally or alternatively, the rear wall and / or side frame can have an edge which is bent over in the lower region and on which a guide component for the pressure rod or the stamp is provided. The pressure rod or the stamp can be passed through an opening on the lower bent edge.

According to a second variant, the rear wall is made from a wood-based material. The rear wall can then have a first recess into which the housing is inserted, on which the adjustment device is mounted. Optionally, a second recess can be provided on the rear wall, in which a guide element for the stamp or the pressure rod is arranged.

The drawer according to the invention is preferably used in furniture in order to be able to adjust the orientation of a front panel of the drawer. The drawer can also be used for household appliances.

The invention is explained in more detail below on the basis of several exemplary embodiments with reference to the accompanying drawings. Show it: Figure 1 is a view of a rear wall of a drawer according to the invention Shen;

Figure 1 1 is a perspective view of a rear wall of a

Drawer according to a further embodiment, for example, and

Figure 12 is a perspective exploded view of the adjusting device of the drawer of Figure 11.

A drawer 1 comprises a base 2, two side frames 3 and a rear wall 4 connecting these side frames 3. On the rear wall 4 is at least a housing 5 with an adjustment device for adjusting the inclination vorgese hen. A rotating part 6 is rotatably mounted on the housing 5 and can be rotated relative to the housing 5 via an actuating section 7.

As can be seen from the enlarged views of FIGS. 2A and 2B, the actuating section 7 can be pivoted by 180 °, for example, from the upwardly pointing position shown in FIG. 2A, as shown in FIG. 2B. As a result, the drawer 1 is raised relative to a pull-out guide 10. The pull-out guide 10 comprises a guide rail 11 which can be fixed to a furniture body, a central rail 12 and / or a running rail 13 on which a protruding hook 14 is formed. The Ha ken 14 engages in a stamp 8 which is connected to the rotating part 6 via a pressure rod 15. The stamp 8 is guided on a lower portion of the housing 5 and can be rela tively moved to the push rod 15 via an eccentric on the rotating part 6 in order to adjust the height of the rear wall 4.

In this exemplary embodiment, the rear wall 4 is made from a bent steel sheet and comprises an upper bent edge 40 and a lower bent edge 41, which are bent in a U-shape in cross section. At the upper edge 40, an upper portion of the housing 5 is inserted, while rend at the lower edge 41, a lower portion of the housing 5 is inserted. On the lower edge 41 there is an opening through which the punch 8 and / or the hook 14 are passed.

In FIG. 4, the rear wall 4 is shown without the pull-out guide 10. On the punch 8, a receiving portion 20 for inserting the hook 14 is formed out. The punch 8 is held ver slidably in the housing 5 in a lower portion.

As can be seen from FIGS. 5 and 6, the housing 5 has a downwardly open guide channel 16 in a lower area into which the stamp 8 is inserted from below. The punch 8 has a guide web 19 on the side, which is inserted into a corresponding groove on the guide channel 16. Furthermore, a channel for receiving the pressure rod 15 is formed on the housing 5, which channel is also pushed into the guide channel 16 from below. The pressure rod 15 is inserted into an upper receptacle on the punch 8 and is arranged on its upper side on an eccentric 17 of the rotating part 6.

The rotating part 6 is rotatably held on a bearing 60 of the housing 5, see above that by rotating the rotating part 6 of the eccentric 17 acts on an end face of the pressure rod 15 to push the pressure rod 15 relative to the housing 5 to ver. As a result, the rear region of the drawer can be changed relative to the running rail 13 of the pull-out guide 10, in particular in order to adjust the inclination of the front panel of the drawer 1. The housing 5 is connected to a side frame 3 via one or more lateral tabs 18.

In Figure 7, a further embodiment of a drawer is shown, in which a rotating part 26 of an adjusting device is arranged on a rear wall 4 made of a bent sheet steel. The rotating part 26 is accessible from a front side of the rear wall 4, that is to say from the interior of the drawer, and can be rotated by a tool to adjust the height or the inclination of the drawer.

FIG. 8 shows a rear view of the rear wall 4 of FIG. 7, and it can be seen that a modified housing 25 of an adjusting device is fixed on the rear wall 4, on which the rotary part 26 is rotatably mounted. The housing 25 is fixed via locking projections 27 to openings of a bent edge 40 of the rear wall 4 in the upper area, but can also be attached by other means. In the housing 25, a push rod 15 is inserted, preferably from below, which cooperates with the rotating part 26 for a height adjustment. The pressure rod 15 engages in the lower area in a modified punch 8 which is slidably mounted on a lower edge 41 of the rear wall 4. For the displaceable mounting of the stamp 8, it has two webs 31 with projections 32 which are guided in bent tabs 42 of the rear wall 4. For this purpose, corresponding openings, preferably as elongated holes, are cut out on the bent tabs 42. Optionally, the stamp 8 could also be immovably fixed to the tabs 42, in which case the pressure rod 15 is passed through the stamp 8 and rests directly on an upper side of the running rail.

In FIG. 9 it becomes clear that the stamp 8 can also be designed with more than one, in the present exemplary embodiment, with two receiving sections 20. These receiving sections 20 are arranged next to one another in the longitudinal direction of the rear wall, one of the two receiving sections preferably being covered by a bent edge 41 in the lower region of the rear wall 4. In FIGS. 10A and 10B, the adjusting device is shown without the rear wall 4. The rotary part 26 is held in a rotary bearing 28 on a housing 25 and is formed integrally with an eccentric 29. The eccentric 29 contacts an end face of the pressure rod 15 so that the pressure rod 15 is moved relative to the housing 25 in the direction of the running rail 13 by rotating the rotating part 26. Resilient latching webs with latching projections 27 are also integrally formed on the housing 25 and can be inserted into corresponding openings on the upper edge 40 in the upper region of the rear wall.

The pressure rod 15 is inserted on its underside in a receptacle 33 of the stamp 8. The punch 8 is guided over the two webs 31 on the tabs 42 of the rear wall 4. The pressure rod 15 is supported by the stamp 8 on an upper side of the rail 13. Alternatively, the pressure rod 15 can contact the rail 13 directly.

In FIGS. 11 and 12, a further embodiment of a drawer is shown in the rear area, a modified rear wall 4 'being used as a plate, in particular a plate made of a wood material, plastic or another material. In the rear wall 4 'a recess 45 is rich in the upper Be and a recess 55 is introduced in the lower region, in particular as blind holes.

In the upper recess 45, a housing 44 of an adjusting device is inserted, on which the rotary part 6 already described above with an Actuating section 7 is rotatably arranged. The rotating part 6 acts via an eccentric 17 on an end face of the pressure rod 15, which is guided on a guide element 50 in the lower area. The guide element 50 is inserted into the lower recess 55 and comprises a channel for the displaceable mounting of a stamp 8. The stamp 8 is fixed to a hook 14 of the rail 13 via a receiving section 20. By rotating the rotating part 6, the pressure rod 15 can be adjusted relative to the rear wall 4 ', so that a height adjustment takes place, as already explained in the first embodiment.

In the illustrated embodiments, an eccentric 17 or 29 is used to adjust the Drucksta bes 15 relative to the housing 5, 25 and 44. It is also possible to use a worm, an adjusting screw or another adjusting element instead of an eccentric. The pressure rod 15 can optionally be supported directly on the rail 13 of the Auszugfüh tion 10 or via a stamp 8. The stamp 8 can be fixed to the pressure rod 15 by fastening means or by gluing.
