Side arm release system for eyeglass frame with changeable temple pieces

Abstract

A side arm release system for an eyeglass frame includes front frame having outer edges, each of the edges terminating in a vertical line substantially parallel to a plane defined by the eyeglasses or the like held within the front frame. The vertical line functions as a fulcrum for the release function. The system further includes a pair of axle journals, one each of the journals of the pair integrally depending from the inner surface of each outer end of the front frame, the journal projecting in a direction generally normal to the plane of the eyeglasses held within the front frame. The journals are located proximally to the fulcrum within a dimension having a width of the forward-most ends of side arms. The system also includes a pair of male bayonet clips, each rotationally dependent at one end from axles within respective the journals of the eyeglass frame, and inwardly of the fulcrum in the direction of a nose bridge of the front frame. Each of the temple pieces exhibit a forward end terminating in a vertical camming surface which contacts the fulcrum upon rotation of the arms or temple members. A pair of female bayonet clips are proportioned for complemental engagement of opposing male bayonet clips, the female clips formed integrally upon inner sides of each temple piece proximally to each of the male bayonet clips when the male clips are press- fitted into the female clips. The outward rotation of temple members causes a lever action of the camming surface upon the fulcrum, pulling on the male bayonet clip. Rotation of the eyeglass frame oppositely in direction to the rotation of the side arm will also pull the male bayonet clip out of engagement with its associated female clip and in the direction of the eyeglass frame.

Description

Technical field [0001] The invention relates to a spectacle system with temples or temple pieces that can be changed in a selectable manner. Background technique [0002] In the past, glasses having temple pieces have been proposed, the configuration, color, or design of the temple pieces can be changed. For example, U.S. Patent No. 5,321,442 (1994) entitled Spectacles with, for example, removable lenses, side bars, and adjustable temples by Albanese discloses spectacles with removable temples including the following sleeves, The sleeve can be stuck on the temple piece or slipped from the temple piece. In Gitlin's U.S. Patent No. 3,582,192 (1971) named Detachable Decorative Sleeves for Glasses, Cooper's U.S. Patent No. 5,185,620 (1993) named Glasses System, and Kirschner's U.S. Patent No. 5,185,620 (1993) named Decorative Sunglasses US Patent No. 5,652,635 (1997) teaches other concepts for providing eyeglasses or sunglass frame systems with temple pieces that can be changed in ...
