Height adjustment device for a drawer

The innovation concerns a height adjustment device for a drawer according to the generic term of claim 1.

So far, it is only known to provide a height adjustment device between a front panel and the drawer itself in order to set the drawer at the correct angle.

The aim of the innovation is to make such a device simpler and more cost-effective and also to make it more accessible.

To solve the problem posed, the innovation is characterized by the technical teaching of claim 1.

The essential feature of the innovation is that/3 a detachable, spring-loaded connection is arranged between at least the front part of the drawer and the associated part of the drawer-side guide rail and that/8 a height adjustment part is arranged in the area of this detachable, spring-loaded connection.

In a preferred embodiment of the present innovation, it is provided that this height adjustment part is designed as a push-off part, which essentially has a wedge-shaped run-up curve that is positioned in the space between the drawer and the associated guide rail and determines the distance between the two mentioned parts.

It is preferred if this wedge-shaped run-on part is arranged on the free, pivotable end of a lever so that it can be easily operated.

If the drawer-side guide rail is arranged below the drawer, the height adjustment part is easily accessible, because the height adjustment part, which is designed as a lever, is attached to the spring-loaded clip-on part, which in turn is attached to the underside of the drawer.

Of course, the kinematic reversal is also included in the present innovation, namely that the spring-loaded part itself is arranged on the guide rail and an associated locking recess is arranged on the underside of the drawer.

In this case, the height adjustment part can be arranged either on the drawer base or on the angle arranged there or on the drawer-side guide rail.

Instead of the rotating lever described here with a corresponding run-up curve, eccentric levers can also be used, which, with a corresponding eccentric roller curve, adjust the distance between the drawer base and the drawer-side guide

rail and make this distance adjustable.

Of course, the innovation is not limited to the fact that the drawer-side guide rail is attached detachably and lockably below the drawer bottom. In another embodiment, the drawer rail is arranged next to the drawer (ie on the side), with a corresponding eccentric lever then also engaging in the space between the drawer-side guide rail and the bottom of the drawer.

A further embodiment of the present innovation is claimed, in which the lever does not act as a height adjustment lever, but as a side adjustment lever. In this embodiment, the guide rail is arranged laterally next to the drawer side wall and the locking arrangement is also located on the drawer side, with the previously described adjustment lever again being squeezed into this gap and changing the distance between the guide rail and the drawer side wall with its wedge-shaped run-on curve, so that the side play of the drawer can be adjusted in relation to the drawer-side guide rail.

The subject matter of the present innovation arises not only from the subject matter of the individual protection claims, but also from the combination of the individual protection claims with one another.

All information and features disclosed in the documents, including the summary, in particular the spatial configuration shown in the drawings are claimed as essential to the invention, insofar as they are individually

or in combination are new compared to the state of the art.

The innovation is explained in more detail below using drawings that merely show one way of implementing it. The drawings and their descriptions reveal further key features and advantages of the innovation.

and 9 : A top view of the drawer interior.

Figures 1 and 5 show the new adjustment lever 1 in side view and top view. As can be seen from Figure 3, this is attached to a connector 2, which connects the drawer 6 to the drawer guide rail 8.

The connector 2 is a snap-in connector and consists of a profile which is preferably attached to the underside or front panel of the drawer and is provided with a snap-in spring 5 which snaps into an associated snap-in recess 9 in the drawer guide rail.

The locking connector 2 thus ensures a firm connection between the drawer 6 and the drawer guide rail 8, which can be released at any time with little effort. The adjustment lever attached to the locking connector 2

1 is in the locked state of the snap connector

2 between drawer 6 and drawer guide rail 8.

The approximately wedge-shaped overrun part 4 can be rotated about an axis 12 via the lever arm 3.

0 If now - as shown in Figure 8 - the lever

3 is rotated in the direction of arrow 10, the approximately wedge-shaped run-on part 4 slides between the guide rail 8 and the drawer 6, as shown in Figure 9.

As a result, as can be seen from Figure 7, the drawer 6 is raised in the direction of arrow 11 and its height is adjusted compared to Figure 6.

It would of course be equally conceivable to make a lateral adjustment in this way instead of a 0 height adjustment.

Instead of the adjustment lever with the overrun part, an eccentric screw can of course also be used, which serves the same purpose of being able to move between the drawer

and drawer guide rail and thus adjust the distance between the two.

The innovation ensures simple, cost-effective and easily accessible height adjustment.
