Abstract

A corner connector for connecting at least two frame profiles of a frame rack arranged perpendicular to each other, which frame rack consists of a plurality of pieces, at least one of which is designed to bear against one or more of the frame profiles, characterized in that the piece which is designed to bear against one or more of the frame profiles is a first molded sheet metal part with a receiving opening in which or on which a threaded sleeve is situated.

First claim

The invention claimed is:

1. A corner connector for connecting at least two frame profiles of a frame rack which are arranged perpendicular to each other, having a plurality of pieces, at least one of which is designed to bear against one or more of the frame profiles, comprising:
wherein the piece which is designed to bear against one or more of the frame profiles is a first molded sheet metal part with a receiving opening in which or on which a threaded sleeve is situated, wherein the threaded sleeve is press-fitted in the receiving opening or welded in or on the receiving opening, wherein the first molded sheet metal part has at least two legs emerging from a central piece, the two legs being perpendicular to each other, for engaging with the respective frame profile and for bearing against at least one inner wall of a respective frame profile, wherein the receiving opening is formed in the central piece, and wherein a second molded sheet metal part is provided, which has a reference surface for the central piece of the first molded sheet metal part, and
wherein the reference surface has another receiving opening having dimensions which correspond to the receiving opening of the first molded sheet metal part, and the threaded sleeve being press-fitted in the other receiving opening of the reference surface or welded on or in the other receiving opening.

2. The corner connector according to claim 1 , wherein at least one leg emerges from the reference surface for engagement with a third frame profile.

3. The corner connector according to claim 2 , wherein the at least one leg has a passage.

4. The corner connector according to claim 1 , wherein the legs of the first molded sheet metal part are bent.

5. The corner connector according to claim 1 , wherein the legs or bent regions of the legs have lugs and the reference surface is formed on a central plate, which is contoured so that the reference surface lies against the lugs of the first molded sheet metal part.

6. The corner connector according to claim 1 , wherein the central plate has an opening which remains accessible when the frame profiles are placed on the corner connector.

7. A corner connector for connecting at least two frame profiles of a frame rack which are arranged perpendicular to each other, comprising:
a first metal part having;
two legs extending perpendicular to each other from a central portion, the legs each being configured to bear against a frame profile;
the central portion having a circular opening therein;
a threaded sleeve having a top and a bottom;

a second metal part having:
a central portion;
the central portion of the second metal part having a circular opening therein lying below the central opening in the first metal part, and
the bottom of the threaded sleeve being attached to the opening in the central portion of the second metal part and the top of the threaded sleeve being attached to the opening in the central portion of the first metal part, the sleeve remaining accessible when the frame profiles are placed on the corner connector.

8. The corner connector of claim 7 wherein edges of the legs of the first metal part are bent around edges of the second metal part to hold the first metal part and second metal part together.
