Abstract

Drawer pull-out guide comprising a basic-structure rail, which can be fastened on a basic furniture structure, also comprising at least one pull-out rail, which is mounted such that it can be displaced relative to the basic-structure rail between an open position and a closed position, and further comprising at least one lifting device, by means of which the pull-out rail can be raised relative to the basic-structure rail towards the end of the closing movement, wherein the lifting device is of at least two-part design, wherein the lifting device has a raising device, for raising the pull-out rail, and a bearing device, for supporting the pull-out rail in the closed position, wherein the raising device, in the closed position of the pull-out rail, is relieved of the loading of the pull-out rail.

First claim

1 . A drawer extension guide, comprising:
a carcass rail which can be fastened to a furniture carcass, at least one extension rail which is supported displaceable relatively to the carcass rail between an open position and a closed position, at least one lifting device, by way of which the extension rail can be raised relative to the carcass rail towards the end of the closing movement, wherein the lifting device is of at least two-part design, wherein the lifting device has a raising device for raising the extension rail and a bearing device for supporting the extension rail in the closed position, wherein the raising device is relieved of the extension rail in the closed position of the extension rail.

2 . The drawer extension guide according to claim 1 , wherein the extension rail has an elevation directed to the carcass rail and/or the carcass rail has an elevation directed to the extension rails.

3 . The drawer extension guide according to claim 2 , wherein the extension rail can be raised by the interaction of the elevation and the raising device and that the elevation is supported by the bearing device in the closed position.

4 . The drawer extension guide according to claim 2 , wherein the elevation is formed by an embossing of the extension rail and/or of the carcass rail.

5 . The drawer extension guide according to claim 1 , wherein the raising device is formed by a first area and the bearing device is formed by a second area, wherein the first and second area are connected to each other.

6 . The drawer extension guide according to claim 5 , wherein the first area, which is formed by the lifting device, is formed softer than the second area and/or is formed of another material than the second area.

7 . The drawer extension guide according to claim 1 , wherein the raising device comprises at least one lifting rolling body.

8 . The drawer extension guide according to claim 7 , wherein the bearing device comprises at least one supporting rolling body which is separate from the lifting rolling body, wherein it is preferably provided that the at least one lifting rolling body, one the at least one supporting rolling body have the same diameter.

9 . The drawer extension guide according to claim 8 , wherein the at least one lifting rolling body consists of another material than the at least one supporting rolling body.

10 . The drawer extension guide according to claim 8 , wherein the lifting rolling body is formed softer than the supporting rolling body.

11 . The drawer extension guide according to claim 8 , wherein the lifting rolling body consists of plastic and the at least one supporting rolling body is made of metal.

12 . The drawer extension guide according to claim 1 , wherein load transmitting rolling bodies, which are separate from the lifting device, are arranged between the carcass rail and extension rail.

13 . The drawer extension guide according to claim 12 , wherein the rolling bodies are arranged in a common, displaceably supported.

14 . The drawer extension guide according to claim 1 , wherein the raising device and the bearing device are arranged one after the other on a rolling track.

15 . An arrangement comprising a drawer and a drawer extension guide according to claim 1 .
