Description

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

The present invention relates to a drawer having at least two adjustable vertical sides and a panel attached to the front side of the side wall.

Drawers of the type described above, in particular for the structure of fixing the panel to the front of the side wall and the structure of the means for adjusting the panel, are known in many embodiments.

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

This purpose is that two fastener plates having housings extending in the side wall direction and enclosing the side wall portions at the side are attached to the inside of the panel facing the side wall portion, each housing having a height adjustment eccentric, and It accommodates the clamping eccentric aligned with the height adjustment eccentric, the clamping eccentric engages behind the thrust bearing of each side wall region, the thrust bearing section is elastically pivotable from the plane of the side wall, and the clamping eccentric is the side wall By pressing the housing in the negative longitudinal direction, it moves on the thrust bearing section while deflecting the thrust bearing section, and after the thrust bearing section springs back, it can be brought into the engaged position behind the thrust bearing, and then the height adjustment eccentric is Front recess of the side wall Made in accordance with the invention is placed in the support system.

This type of configuration comprises relatively few and simple individual parts and ensures high 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.

The fastener plate with the housing which in turn receives the height adjustment eccentric and the 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 fastener area in the side wall. Thus, the panel is pre-fixed against the drawer even without the clamping eccentric operated, and the drawer can be transported in this state without the risk of missing 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 which easily biases the thrust bearing section laterally from the starting position.

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

The thrust bearing section is thus made 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.

With separate installations forming the bearing sections, these separate installations are virtually independent of the materials used in the side walls and can be structurally designed without special treatment of the side walls, so that the clamping eccentric is relatively easy on these thrust bearing sections. The moving advantage and the clamping eccentric also provide the advantage of being firmly engaged behind the thrust bearing.

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

Exemplary embodiments of the invention will be described in the accompanying drawings and will be described in more detail below.

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. In addition, 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 portion 2, a fastener plate having a housing 4 extending and extending in the side wall portion 2 direction and facing each side wall portion 2 in a radial direction ( 3) is fixed to each panel 1, the housing 4 receives the height adjusting eccentric 5 and the clamping eccentric 6 and the side wall 2 so as to surround the side wall 2 side by side. Can be pressed onto the bed. In the pressed state, the height adjustment eccentric 5 is placed in a supporting manner in the front recess 7 of the side wall 2, the clamping eccentric 6 being illustrated in FIGS. 10, 11 and 16. As shown, it meshes behind the thrust bearing 8 in the side wall 2.

Any possible vertical adjustment of the panel 1 with respect to the drawer can be further carried out via the height adjustment eccentric 5, while fixing the panel 1 to the front of the side wall 2 is a clamping eccentric. 6 and thrust bearing 8 are possible.

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 be elastically pivoted from the plane of the side wall 2. When the housing 4 is pressed onto 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 echoed back 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 is engaged behind the thrust bearing 8 and pressed into the recess 10, the panel 1 is first connected to the drawer in place. By actuating the clamping eccentric 6, the panel 1 can be firmly fixed to the front side 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 fastener plate 3 having a vertical leg 3a extending in the direction of the side wall part 2, which side wall part 2 is made in one part with the fastener 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 fastener 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 fastener 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 are each riveted in the holes 12, 13 of the legs 3a provided such that the two eccentrics are rotatably rotatable.

In addition, as shown in FIG. 1, the front recess 7 in the wall portion 2 is opened to the recess 14, and the installation portion 15 can be inserted into and engaged with the recess 14. . The installation part 15, which is made of one piece of elastic plastic, forms the thrust bearing section 9 described above and has an opening 10, the opening 10 being delimited on the fastener plate 3 so that the panel ( The side facing 1) 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 fastener portion 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 faces radially with the clamping eccentric 6, which is advantageously also provided with an clamping eccentric 6 or an access bevel. Through the mounting bevel 15 and the access bevel 16 on the clamping eccentric 6 and through other displacements, the thrust bearing section 9 can now be elastically displaced laterally in the plane of the side wall 2. This possibility guides 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. This now causes the clamping eccentric 6 to engage behind the thrust bearing 8, as shown more clearly in FIG. 16, echoing back to the starting position.

In the position shown in FIG. 16, the panel 1 is first fixed in place in the drawer. By actuating the clamping eccentric 6, it 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 is used to guide a tool, such as a screw driver, to pivot the thrust bearing section 9 in the displacement region of the clamping eccentric 6 when the panel 1 needs to be disassembled. do.

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

In addition, the fixed 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, it is ejected into the recess 14 region of the side wall portion 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 part both in the transverse direction and in the longitudinal direction of the side wall part 2.

16, the clamping surfaces of the crimping eccentric 6 and the thrust bearing 8 are operated so as to be slightly inclined to the rotational axis of the crimping eccentric 6, so that the dynamic load ( Even in the case of a dynamic load, it is ensured that the receiving portion 15 having the thrust bearing 8 and the crimping eccentric 6 cannot be loosened with each other.

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 formfitting overlap of the side wall part 2 in these stepped transition regions, so that a form of form fit between the side wall part 2 and the installation part 15 at least in the clamped state. This is because the transition region is engaged in depressions of the installation portion 15 delimited by the lug 15a in the clamped state. If necessary, it may be sufficient to fabricate a form pit in only one transition area.

The fastener 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 fastener plate 3, the legs 3a and the plate 11 are pressed. It can be seen from FIGS. 2 to 5 that they can be provided as bent-stamped parts and connected by spot welds.

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

As an alternative thereto, however, the mounting unit, which comprises the housing 4 and the fastener 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 one part as a manufactured injection molded part.

18, 19 and 20a to 20e show an exemplary embodiment of the invention, in which the installation part 15 is made as a one-part bent mold part made of metal.

In addition, mountings made of this type of metal may 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 via proper positioning of the free cuts 22, so that the thrust bearing section with the thrust bearing 8 for the crimping eccentric 6 is shown. (9) 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 fastener plate 3 always has an elliptical hole 3c through which the fastener screw can be guided to fix it to the panel 1, which allows horizontal adjustment of the panel 1. This is because these elliptical holes 3c are enabled.
