Abstract: A hollow, thin wall, generally rectangular shaped corner connector key forms the frame corner and connects together the adjacent ends of tubular screen frame members. The legs of the L-shaped key form a hollow box-like corner portion, against which the frame ends are abutted. Integral leg extensions telescopically fit into and are frictionally locked against the interior wall surfaces of the frame members. The hollow, tubular cross-section shape of the key, whose box-like corner portion corresponds to the cross-sectional shape of the exterior of the frame members, and whose leg extensions correspond to the interior cross-section of the frame members, coupled with the frame member abutments and the frictional locking, substantially rigidifies the frame corner and resists out-of-plane twisting or bending of the frame.

Abstract: An angled bolt is used for securing a mitered connection between two plates particularly furniture boards. To obtain a satisfactory fit between the miters, the position of the bolt shanks in the plates must be well fixed. This is obtained by a stop provided on the bolt so as to extend substantially in the plane of the joint. The stop may take the shape of a ring or a star. To be able to assemble plates also in other than right-angle positions, the connecting corner link is designed as a hinge, with the hinge pin extending perpendicularly to the bolt shanks and having flattened protruding ends which form the stops. These stops come automatically into their position in the plane of the joint.
