Abstract

A composed element, such as a piece of furniture, wherein the composed element comprises at least a rear wall, as well as a number of constructional parts forming a whole in which the rear wall has to be provided. The rear wall forms the rear side of the composed element and includes one or more rear wall parts. The composed element comprises seats for installing at least one of the rear wall parts, which are configured such that the rear wall part can be slid into the seats starting from the rear side of the composed element from a position differing from the final plane in which the rear wall part will be situated in the final condition.

First claim

The invention claimed is:

1. A composed element comprising a number of constructional parts interconnected at an angle by means of locking profiles defining at least one corner connection, wherein a tongue and groove coupling with locking parts is applied, wherein said locking parts substantially are located on one side of the tongue only, wherein at both sides of the tongue, opposite-positioned portions are present, including first portions on the side where the locking parts are present, and second portions on the other side, wherein, when the second portions are positioned against each other, there is a spacing between the first portions;
wherein said spacing is less than 1 mm and more than 0.1 mm;
wherein a second spacing is defined on a second side of the tongue opposite the locking parts, the second spacing having a top surface aligned with a top surface of the spacing.

2. The composed element of claim 1 , wherein said spacing is 0.3 to 0.5 mm.

3. The composed element of claim 1 , wherein pretension is integrated into the at least one corner connection.

4. The composed element according to claim 1 , wherein such spacing is applied to two successive corner connections of the composed element.

5. The composed element of claim 1 , wherein the locking parts define an overlap with a pretension between the locking parts at the overlap.

6. The composed element of claim 5 , wherein the pretension acts in a direction offset from a separation direction of the constructional parts.

7. The composed element of claim 1 , wherein the tongue defines a split tongue comprising a gap.

8. The composed element of claim 7 , wherein first portion of the constructional part defining the groove is offset a distance from the second portion of the constructional part defining the groove.

9. The composed element of claim 8 , wherein the first and second portions of the constructional part defining the tongue are offset by the distance between the first and second portions of the constructional part defining the groove and the spacing between the first portions.
