Abstract

A method is provided for producing, by machine and/or by hand, a double-walled drawer frame for a drawer including an inner wall and an outer wall. The method includes the following, in particular carried out chronologically in the order indicated: arranging a spacer part on the inner wall and/or the outer wall, arranging the two walls substantially parallel with each other, displacing the two walls relative to each other in a direction parallel with a longitudinal direction of the walls and/or in a direction transverse to the longitudinal direction, and joining the two walls to each other in the course of the displacement movement.

First claim

The invention claimed is:

1. A method of producing a double-walled drawer frame for a drawer, the drawer frame including an inner wall, an outer wall, and a spacer part therebetween, the method comprising in the order indicated:
arranging the spacer part formed of elastically compressible material on the inner wall or the outer wall,
arranging the inner wall and the outer wall substantially parallel to each other,
elastically compressing the spacer part,
displacing the inner wall and the outer wall relative to each other in a direction parallel to a longitudinal direction of the inner wall and the outer wall, and
joining the inner wall and the outer wall to each other during the displacing.

2. The method according to claim 1 , further comprising compressing the spacer part when the inner wall and the outer wall are arranged substantially parallel to each other.

3. The method according to claim 1 , further comprising gluing the spacer part on the outer wall and/or on the inner wall.

4. The method according to claim 1 , wherein the spacer part is formed substantially cuboid-shaped, the method further comprising gluing the cuboid-shaped spacer part on a lateral face on the outer wall and/or on the inner wall.

5. The method according to claim 4 , wherein an edge of the spacer part is flattened in a direction parallel to a longitudinal direction of the inner wall and the outer wall.

6. The method according to claim 1 , wherein the spacer part has a slot, the method further comprising attaching the spacer part to a front side of the double-walled drawer frame between the outer wall and the inner wall by introducing a longitudinal web located on the front side into the slot.

7. The method according to claim 6 , wherein the slot has an opening configured to widen in a V-shape and/or to be arranged substantially in a direction parallel to a longitudinal direction of the inner wall and the outer wall.

8. The method according to claim 1 , wherein the double-walled drawer frame further includes a guide device including:
a guide groove, and
a guide web,

the method further comprising:
arranging the guide web in the guide groove, and
displacing the guide web in the guide groove in a direction parallel to a longitudinal direction of the walls.

9. The method according to claim 8 , wherein the guide groove and the guide web has a substantially semicircular bend of a sheet metal part, the method further comprising:
after or during the arranging the inner wall and the outer wall substantially parallel to each other and elastically compressing the spacer part, arranging the substantially semicircular bend of the guide web in the substantially semicircular bend of the guide groove, and
wherein the displacing the inner wall and the outer wall relative to each other in a direction parallel to the longitudinal direction of the inner wall and the outer wall includes displacing the substantially semicircular bend of the guide web in the substantially semicircular bend of the guide groove.

10. The method according to claim 9 , wherein a radius of the substantially semicircular bend of the guide groove is greater than a radius of the substantially semicircular bend of the guide web.

11. The method according to claim 8 , wherein the outer wall and the inner wall are manufactured from sheet metal, wherein:
the guide web is manufactured from the same piece of sheet metal as the outer wall so as to have a one-piece construction with the outer wall, and/or
the guide groove is manufactured from the same piece of sheet metal as the inner wall.

12. The method according to claim 11 , wherein a front side of the double-walled drawer frame between the outer wall and the inner wall is manufactured from the same piece of sheet metal as the inner wall, and the guide groove is arranged at the front side.

13. The method according to claim 8 , wherein the double-walled drawer frame comprises a first holding device and a second holding device for holding the guide groove on the guide web, the method further comprising:
pushing the guide web in the guide groove and into the first holding device, and
affixing the second holding device to the outer wall.

14. The method according to claim 13 , wherein the first holding device is arranged in a first end region of the guide groove and/or is joined to the guide groove so as to be fixed in place, and
the second holding device is arranged in a second end region of the guide groove and/or is formed as a retaining clip.

15. The method according to claim 8 , wherein the arranging of the guide web in the guide groove comprises displacing the inner wall and the outer wall relative to each other in a direction transverse to the longitudinal direction of the inner wall and the outer wall and/or so that the guide groove encompasses the guide web.

16. The method according to claim 1 , wherein the double-walled drawer frame has a mounting device, the mounting device including:
a mounting groove formed by a bent end piece of the outer wall, and
a mounting web joined to the inner wall,
wherein the method further comprises:
arranging the mounting web in the mounting groove, preferably by displacing the two walls relative to each other in a direction transverse to the longitudinal direction of the walls and preferably so that the at least one mounting groove engages behind the at least one mounting web,
wherein the displacing comprises displacing the mounting web in the mounting groove in the direction parallel to the longitudinal direction of the inner wall and the outer wall.

17. The method according to claim 16 , wherein the mounting web comprises a play compensation device to compensate for play between the mounting groove and the mounting web, wherein the play compensation device is configured to widen the mounting web, the method comprising:
wedging the mounting web in the mounting groove by the play compensation device, and
compressing the play compensation device when the mounting web is arranged in the mounting groove.

18. The method according to claim 17 , wherein the play compensation device is a projection, the projection being flexible and/or having lateral flanks in ramp form.

19. The method according to claim 16 , wherein the arranging of the mounting web in the mounting groove is performed by displacing the inner wall and the outer wall relative to each other in a direction transverse to the longitudinal direction of the inner wall and the outer wall so that the mounting groove engages behind the mounting web.

20. The method according to claim 1 , wherein the double-walled drawer frame has a guide device and a mounting device, the guide device and the mounting device being arranged at two opposing long sides of the outer wall and/or the inner wall, the method further comprising joining the inner wall and the outer wall to each other on the two opposing long sides while displacing the inner wall and the outer wall relative to each other in a direction transverse to the longitudinal direction.

21. A double-walled drawer frame for a drawer comprising:
an inner wall, an outer wall, and
a spacer part arranged between the inner wall and the outer wall,
wherein the double-walled drawer frame is produced by the method according to claim 1 .

22. The double-walled drawer frame according claim 21 , wherein the spacer part:
is substantially cuboid-shaped, and/or
has a slot.

23. The double-walled drawer frame according clai
