CROSS-REFERENCES TO RELATED APPLICATIONS
Not Applicable.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a rack for supporting an object.
2. Description of Related Art
A rack of this kind is disclosed in EP 0 166 095.
It is the object of the invention to form such a rack for supporting an object so as to enhance the load-bearing capacity thereof.
BRIEF SUMMARY OF THE INVENTION
This object is achieved by a rack comprising a pair of parallel corner profiles (
1
) each having two legs (
2
,
3
) connected at an angle along an edge, a groove (
4
) extending parallel to the edge and having a longitudinal portion (
5
) which extends through the edge and which is inclined with respect to the two legs (
2
,
3
) and a transverse portion (
6
) formed at the base of the longitudinal portion (
5
) and extending to both sides thereof with respective first and second portions (
13
,
13
′), bolts (
44
) engaging each of the longitudinal portions (
5
) of the grooves (
4
) and sliding blocks (
20
) positioned in the transverse portions (
6
) and cooperating with the bolts for fastening the object to be supported to the frame, the sliding blocks (
20
) each having a first region (
27
) and a second region (
27
′) being in contact with respective ones of the two portions (
13
,
13
′), characterized in that the two portions (
13
,
13
′) of the transverse portion (
6
) and the contacting two regions (
27
,
27
′) of the sliding block (
20
) are both inclined towards each other so as to produce a formfit connection between the sliding block (
20
) and the transverse portion (
6
).
Advantageously, the two legs of the corner profile do nto bend up even under high loads because the form-fit produced between both portions of the groove and the corresponding regions of the sliding block cooperates in stabilizing the connection.
