Abstract

A corner construction fastening one cabinet plate member to another cabinet plate member by using a joining element, the cabinet plate members having a pair of inner and outer walls at both sides and the joining element having a body to support the walls and under sides of the members and two extensions to be inserted into slots formed in end portions of the walls.

Claims

1. A corner construction comprising:

(a) a joining element having;

(i) an angular body which is lowered at the front end of a right angle or an obtuse angle consisting of two straight sides and

(ii) two extensions each of which has a rib and

(b) two angularly related plate members each of which has a pair of two spaced walls, the end portions of the two outer walls being cut out in order to meet each other in making corner joints and the end portions of the two inner walls each having a slot sized, shaped, and positioned to receive one of said extensions of said joining element so that said joining element is engaged against said corner joints and holds them firmly.

2. A corner construction according to claim 1 wherein said angular body has a certain thickness to support said two spaced walls of said angularly related plate members.

3. A corner construction according to claim 1 wherein said ribs are outwardly turned.

4. A corner construction according to claim 1 wherein said two angularly related plate members are made by bending a sheet plate.

5. A corner construction according to claim 1 wherein said two angularly related plate members are made by two separate sheet plates.

6. A corner construction according to claim 1 wherein said two spaced walls are made by a bending operation.

7. A corner construction according to claim 1 wherein said two angularly related plate members are made by a molding process.

8. A corner construction according to claim 1 wherein each one of said slots is made so that it leans toward the end portion of the corresponding one of said inner walls.
