Description

Drawer with two side frames and one cover {DRAWER COMPRISING TWO LATERAL FRAMES AND A COVER}

The invention relates to a drawer which is adjustable with respect to the drawer in at least the vertical direction and has two side walls and a panel attached to the front of the side walls.

Drawers of the above-mentioned type are known in many embodiments, in particular for the construction of fixing the panels to the front of the side walls and the construction of the means for adjusting the panels.

The present invention is based on the object of providing a drawer of the type according to the kind distinguished by a simple configuration, in particular comprising only some individual parts for fixing and adjusting the panel on the front of the side wall.

This object is achieved in accordance with the present invention, wherein the two fastener plates with housings extending in the side wall direction and enclosing the side walls on the side are attached to the panel in an interior facing the side wall, respectively. The housing of the housing accommodates the height adjustment eccentric and the clamping eccentric aligned with the height adjustment eccentric, the clamping eccentric engages behind the thrust bearing in each side wall area, and the thrust bearing section pivots elastically from the plane of the side wall. Preferably, the clamping eccentric moves on the thrust bearing section during deflection of the thrust bearing section by pressing the housing in the longitudinal direction of the side wall, and after the thrust bearing section springs back into the engaged position behind the thrust bearing. May come, and then the height adjustment Groups are placed to be supported in the forward recess of the side wall.

This type of configuration comprises relatively few and simple individual parts and ensures a high degree of pre-installation or pre-assembly, so that the final assembly of this drawer, in particular here the connection and adjustment of the panel, can be carried out easily and quickly.

A fixture plate with a housing that also receives a height adjusting eccentric and a clamping eccentric can be fully preassembled. In order to connect the panel to the side wall of the drawer, the panel with the housing only has to be pressed on the side wall and then locked against the fixture area in the side wall. Thus, the panel is also pre-secured against the drawer even without the clamping eccentric actuated, and the drawer can be transported in this state without risk of losing the panel.

In order to allow the clamping eccentric to move easily on the thrust bearing section, the clamping eccentric and / or the thrust bearing section have an access bevel that facilitates deflecting the thrust bearing section laterally from the basic position.

According to another feature of the invention, the thrust bearing section comprises a flexible spring member formed by free cuts provided on the side wall.

The thrust bearing section is thus produced in one piece with the side wall, which is of course particularly advantageous in terms of cost.

However, the thrust bearing section may also include installed parts fixed on the side wall.

Preferably, this type of installation is provided to be able to engage in a corresponding recess in the side wall.

The use of separate installations to form the bearing sections allows these separate installations to be designed virtually independent of the material used for the side walls and to be structurally designed without special treatment of the side walls, such that the clamping eccentric moves and clamps on these thrust bearing sections. It also provides the advantage that the eccentric is relatively easy to securely engage behind the thrust bearing.

Other features of the invention are the subject of the other dependent claims.

In essence, the present invention relates to the ability to fix and adjust the panel 1 (see FIGS. 15 and 16) of the drawer on the front of the side wall 2 of the drawer, thus completing all the individual parts in the drawing for clarity. Drawers have been omitted. Also, only one of the side walls 2 of the drawer is shown for simplicity.

In order to fix this panel 1 to the side wall 2, it has a housing 4 which extends and is positioned in the direction of the side wall 2, and a fixture plate 3 opposite to each side wall 2. ) Is fixed to each panel 1, the housing 4 on the side wall 2 to receive the height adjusting eccentric 5 and the clamping eccentric 6 and to surround the side wall 2 side by side. Can be stressed on. In the pressed state, the height adjusting eccentric 5 is placed supported in the front recess 7 of the side wall 2, the clamping eccentric 6 being exemplarily shown in FIGS. 10, 11 and 16. It is shown behind the thrust bearing 8 in the side wall 2, shown.

Any possible vertical adjustment of the panel 1 to the drawer can be further carried out via the height adjustment eccentric 5, while fastening the panel 1 firmly against the front of the side wall 2 is clamped. It is possible through the eccentric 6 and the thrust bearing 8.

All exemplary embodiments share this basic construction principle.

In addition, all exemplary embodiments share the feature that the thrust bearing section 9 with the thrust bearing 8 can in particular be elastically pivoted from the plane of the side wall 2. When the housing 4 is pressed on the side wall 2, the clamping eccentric 6 can move on the thrust bearing section 9 by deflecting the thrust bearing section 9 laterally, and the recess 10 The extent of the recessed area towards the panel 1 until it lies in the area forms the thrust bearing 8 described above. In this position, the thrust bearing section 9 is elastically restored to its original position, such that the clamping eccentric 6 is engaged behind the thrust bearing 8.

This is particularly clearly shown in FIGS. 15 and 16.

As soon as the clamping eccentric 6 engages behind the thrust bearing 8 and is pressed into the recess 10, the panel 1 is first connected to the drawer in place. By operating the clamping eccentric 6, the panel 1 can be firmly fixed to the front of the side wall 2.

If height adjustment of the panel 1 is required, such height adjustment is made before the panel 1 is finally fixed by actuating the height adjustment eccentric 5.

In the following, specific features of the individual exemplary embodiments will be described.

1 shows a fixture plate 3 with a vertical leg 3a extending in the direction of the side wall 2, which side wall 2 is made of a single piece with the fixture plate 3. This leg 3a forms the first half of the housing 4 described above. The separately produced plate 11 has a base band 11a, which can be inserted into the slot 3b of the fixture plate 3 using the band 11a, and then parallel with the legs 3a. Can be brought in position. In this position, the plate 11 is connected to the fixture plate 3 by any method such as welding, gluing, crimping or the like. Thus, the housing 4 is formed by the legs 3a and the plate 11.

The height adjusting eccentric 5 and the clamping eccentric 6 each have holes 12 and 13 in the leg 3a provided to allow both the height adjusting eccentric 5 and the clamping eccentric 6 to be quietly rotatable. Is riveted within.

In addition, as shown in FIG. 1, the front recess 7 in the wall 2 is opened to the recess 14, and the installation part 15 can be inserted into and engaged with the recess 14. . This installation part 15, made of a single piece of elastic plastic, forms the thrust bearing section 9 described above and has an opening 10, the opening 10 being delimited on the fixture plate 3 so as to provide a panel 1. The side facing) forms a thrust bearing 8 for the clamping eccentric 6 by the edge.

The installation part 15 has a trough shaped access bevel 16 on the side facing the fixture part 3 and the panel 1, the access bevel 16 being particularly clearly shown in FIG. 7. In the intermediate mounting step shown in FIG. 15, this access bevel 16 is opposite to the clamping eccentric 6, which clamping eccentric is advantageously carried out with the access bevel. Through other displacements and through the access bevel 16 on the installation 15 and the clamping eccentric 6, the thrust bearing section 9 can now be elastically displaced laterally from the plane of the side wall 2. The possibility therefore arises for guiding the clamping eccentric 6 on the thrust bearing section 9 until the clamping eccentric 6 reaches the region of the opening 10 of the installation 15. It is now elastically restored to the starting position so that the clamping eccentric 6 is engaged behind the thrust bearing 8, as shown more clearly in FIG. 16.

In the position shown in FIG. 16, the panel 1 is first fixed in position substantially on the drawer. By operating the clamping eccentric 6, the panel can be pressed against the thrust bearing 8, and the panel 1 can be fixedly clamped on the front side of the side wall 2.

If height adjustment of the panel 1 is required, the height adjustment of the panel is carried out before the clamping eccentric 6 is tightened.

16 also shows more clearly that the leg 3a has an opening 17 in the thrust bearing section 9 area. This opening 17 can guide a tool, such as a screwdriver, to pivot the thrust bearing section 9 out of the displacement region of the clamping eccentric 6 when the panel 1 needs to be disassembled. Used to

As shown more clearly in FIGS. 17 and 16, the mounting portion has a spring web 18 in the rear end region facing away from the panel 1, the spring web 18 being provided with a mounting portion 15. While in the mounted state it is supported on one side of the side wall 2, the contact area 19 of the installation part 15 opposite to the spring web 18 is on the other side of the particular side wall 2. Is supported. Thus, the installation part 15 is fixed to the rear end with respect to the side wall 2.

In addition, the stationary cam 20 (see FIG. 6) is molded into the rear end region of the mounting portion 15 and, when the mounting portion 15 is mounted, protrudes into the recess 14 region of the side wall 2. Meshes behind the lug 21 (see FIG. 1A).

By means of the aforementioned means, the installation part 15 is fixed to the side wall 2 in the transverse direction and in the longitudinal direction of the side wall 2.

In addition, as clearly shown in FIG. 16, the clamping surfaces of the crimping eccentric 6 and the thrust bearing 8 working together run slightly inclined to the axis of rotation of the crimping eccentric 6. This ensures that the receptacle 15 with the thrust bearing 8 and the crimping eccentric 6 are not loosened with each other even in the case of dynamic loads.

In addition-as shown in the alternative embodiment of FIG. 14-the installation part 15 places a protruding lug 15a in the transition region between the recess 7 and the recess 14 of the side wall 2. At this time, the protruding lug 15a is enlarged. This results in a fitting overlap of the side walls 2 in these stepped transition regions, thus providing a kind of fit between the side wall 2 and the installation part 15 at least in the clamped state. fit occurs because the transition region engages in depressions of the installation part 15 delimited by the lug 15a with the clamped state. If necessary, it may be sufficient to fabricate a fit in only one transition area.

The fixture plate 3 with the housing 4 can be manufactured as a whole from a plurality of individual parts, for example, after being assembled with the fixture plate 3, the legs 3a and the plate 11 are bent. It can be seen from FIGS. 2 to 5 that they can be provided as stamp-stamped parts and connected by spot welds.

In this case, for convenience the clamping eccentric 6 is mounted before the plate 11 is connected to the fixture plate 3.

As an alternative to this, however, the mounting unit, which comprises the housing 4 and the fixture plate 3 made of the legs 3a and the plate 11 and is completely shown in FIG. 5, is made of metal or plastic, for example. It is also conceivable to be produced in a single piece as a manufactured injection molded part.

18, 19 and 20A-20E show an exemplary embodiment of the invention, in which the installation part 15 is made as a single piece of bent mold made of metal.

Furthermore, mountings made of this type of metal can be designed by forming suitable spring tabs and other supports, which may be fixed inside the recesses 14 of the side walls 2.

Finally, FIG. 21 design the side wall 2 through proper positioning of the free cuts 22, so that the thrust bearing section 9 with the thrust bearing 8 for the crimping eccentric 6 is shown. ) Shows the possibility that it can be designed as a bow-shaped spring member. By accomplishing this purpose, shown in FIGS. 21-23, no additional installation part 15 may be necessary at all.

In summary, it should be noted once again that the greatest advantage of the present invention is that a number of parts required for fixing and adjusting the panel 1 of the drawer can be prefabricated to a good degree and pre-mounted. The pre-mounted unit can be provided so that even a less technically skilled end user can fix the panel 1 to the drawer and adjust it as necessary.

In any case, the fixture plate 3 always has an elliptical hole 3c, through which the fastener screw can be guided to secure the panel 1, which allows the horizontal adjustment of the panel 1 to be carried out. It is because it becomes possible by the elliptical hole 3c.
