ABSTRACT:
A pivotal rivet assembly for use in swingably securing a riveted member to a companion member, comprising a pivotal rivet member having a rivet shank portion for pre-riveting, and an integrally-formed, cylindrical head, an outer portion of which head is provided with a pair of diametrically-opposed lugs the under-surfaces of which lie in a common plane perpendicular with respect to the axis of symmetry of the rivet and in spaced, parallel relation with respect to the annular shoulder defined by the juncture of the rivet shank portion with the rivet head. The companion member to be swingably attached is provided with a through opening, the peripheral size and shape of which opening is complemental with the outer peripheral shape of the pivotal rivet head and its integral lugs to permit passage therethrough of said rivet head upon assembly or disassembly. The thickness of the companion member swingably joined is somewhat less than the length of the pivotal rivet head between the undersides of its opposed lugs and the annular shoulder to admit a resilient, split-ring retainer in circumjacent embracing disposition for constraining the riveted and companion members to relative swinging movement.
