CORNER JOINT ASSEMBLY FOR DOOR MOUNTING FRAME AND DOOR MOUNTING FRAME INCORPORATING SUCH ASSEMBLY

摘要

At least one tab (34,36) extends from the first frame (10), being preferably of one-piece structure with it, and is spot-welded to the second frame. The points at which the at least one tab is spot-welded to the second frame are defined by studs (38) produced by embossing in the unwelded state. The second tab (36) is so angled in its extent from the abutting area (22) of the first frame that on fitting together of the frames it locates on the area of the second frame abutting over the corner. One of the two frames, preferaby the first, is horizontally arranged and the other second frame is a side structure of the first. The horizontal frame is composed of two part components (18,20), of which the first (18) is an angle with two arms (22,30).
