ABSTRACT:
The invention relates to the method of making a hinge joining rigid plastic pieces at least one fourth inch thick and includes machining a series of hinge knuckles along straight edges of first and second pieces of rigid plastic, machining keyhole shaped passages perpendicular to and across the width of hinge knuckles of the pieces, the keyhole shaped passages each having a tubular central portion and an outwardly extending slot of narrower width on one side of each knuckle, each hinge knuckle having a width less than the space between adjacent knuckles so that the knuckles of each of the two pieces may be assembled by interleaving the hinge knuckles, and inserting a hinge pin through the aligned tubular central portion to hinge together the first and second pieces. The invention also relates to the hinge structure as so manufactured.
