ABSTRACT:
Disclosed is a hinge assembly for an eyeglass frame which comprises a male hinge member to which a female hinge member is pivotally interconnected. The female hinge member includes a pair of parallel hinge leaves which are joined by a connecting wall in the outer side of the female hinge member. Each hinge leaf includes a pin-receiving slot perpendicular to the longitudinal axis of the female hinge member and a ramp leading to the slot. A raised surface positioned between each ramp and the connecting wall helps guide a pin along the ramp. The male hinge member includes a hinge ear with a pin extending above and below it. The male hinge member and the female hinge member are brought together by inserting the hinge ear between the hinge leaves, with the pin aligned against the side of the raised surfaces as a guide, and forcing the members together so that the pin travels along the ramps until it is engaged by the pin-receiving slots.
