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.
