Rear-wall insert wedge

1. An insert wedge configured for fixedly clamping a first panel within a groove in a second panel, the insert wedge comprising:

a square angle which has a broad limb and a wedge-like, narrow limb; and

a spring tongue which is integrally formed on an outer side of the broad limb and extends by way of its free tongue end beyond an outer side of the narrow limb;

wherein the narrow limb has a slot, which is open to the outer side of the said narrow limb and runs parallel to the spring tongue, close to a transition region to the spring tongue.

2. The insert wedge according to claim 1 , wherein the outer side of the narrow limb and an inner side of the broad limb form an angle of 90°.

3. The insert wedge according to claim 1 , wherein the spring tongue is inclined in relation to the inner side of the broad limb.

4. The insert wedge according to claim 1 , wherein the outer side of the spring tongue smoothly adjoins the outer side of the narrow limb.

5. The insert wedge according to claim 4 , wherein the outer side of the narrow limb and the outer side of the spring tongue form an angle of between 10° and 20°.

6. The insert wedge according to claim 1 , wherein the outer and/or inner side of the narrow limb and/or the outer side of the spring tongue has projections.

7. The insert wedge according to claim 1 , wherein the broad limb has a cutout which is open to the inner side of the said broad limb and to the outer side of the said broad limb, which outer side is averted from the narrow limb.

8. The insert wedge according to claim 1 , wherein the outer side of the narrow limb and/or the outer side of the spring tongue forms a flat or a corrugated contact area.

9. The insert wedge according to claim 1 , wherein the narrow limb and/or the spring tongue are/is in the form of a solid wall or are/is formed by a series of spaced-apart vertical struts.

10. The insert wedge according to claim 1 , wherein the broad limb has a protruding pin on its inner side.

11. An arrangement comprising two panels which are connected to one another, the first panel from amongst the said two panels being inserted into a groove in the other, second panel, and comprising an insert wedge according to claim 1 , wherein the wedge-like, narrow limb of the said insert wedge is pushed in a clamping manner into a gap, which is present within the groove when the first panel is inserted, until the broad limb bears by way of its inner side against the second panel, and the spring tongue of the said insert wedge is straightened and pressed against the first panel, wherein the second panel has a bore which is, in particular, open to the groove, a pin of the insert wedge, which pin projects from the inner side of the broad limb, engaging in the said bore.

12. The arrangement according to claim 11 , wherein a groove width of the groove is larger than a panel thickness of the first panel by at most the width of the narrow limb.

13. The insert wedge according to claim 4 , wherein the outer side of the narrow limb and the outer side of the spring tongue form an angle of 15°.

14. An insert wedge configured for fixedly clamping a first panel within a groove in a second panel, the insert wedge comprising:

a square angle which has a broad limb and a wedge-like, narrow limb; and a spring tongue which is integrally formed on an outer side of the broad limb and extends by way of its free tongue end beyond an outer side of the narrow limb;

wherein the broad limb has a cutout which is open to the inner side of the said broad limb and to the outer side of the said broad limb, which outer side is averted from the narrow limb.

15. The insert wedge according to claim 14 , wherein the outer side of the narrow limb and an inner side of the broad limb form an angle of 90.

16. The insert wedge according to claim 14 , wherein the spring tongue is inclined in relation to the inner side of the broad limb.

17. The insert wedge according to claim 14 , wherein the outer side of the spring tongue smoothly adjoins the outer side of the narrow limb.

18. The insert wedge according to claim 17 , wherein the outer side of the narrow limb and the outer side of the spring tongue form an angle of between 10 and 20.

19. The insert wedge according to claim 14 , wherein the outer and/or inner side of the narrow limb and/or the outer side of the spring tongue has projections.

20. The insert wedge according to claim 14 , wherein the narrow limb has a slot, which is open to the outer side of the said narrow limb and runs parallel to the spring tongue, close to a transition region to the spring tongue.

21. The insert wedge according to claim 14 , wherein the outer side of the narrow limb and/or the outer side of the spring tongue forms a flat or a corrugated contact area.

22. The insert wedge according to claim 14 , wherein the narrow limb and/or the spring tongue are/is in the form of a solid wall or are/is formed by a series of spaced-apart vertical struts.

23. An insert wedge configured for fixedly clamping a first panel within a groove in a second panel, the insert wedge comprising:

a square angle which has a broad limb and a wedge-like, narrow limb; and a spring tongue which is integrally formed on an outer side of the broad limb and extends by way of its free tongue end beyond an outer side of the narrow limb;

wherein the broad limb has a protruding pin on its inner side.
