Abstract
Fastening means for attaching eyeglass members together includes a barbed locking pin inserted into a bushing. More particularly, rimless eyeglasses require new technology to render them long-lasting and fail-safe. Said unique means of attachment is a highly effective replacement for the typical screw attachment means in many eyeglass configurations, including rimless and rimmed versions. In one embodiment, the barbed pin is inserted into the bushing such that the barbs restrict removal. The barbs can be spaced circumferentially along a length of the pin or can be intermittently distributed along the pin. In another embodiment, co-planer barbs along the pin create additional sharp corners to facilitate a connection between the pin and bushing. In a preferred embodiment the barbs are metal. The invention disclosed facilitates fail-safe attachment of eyeglass members together including a temple hinge mounting-bracket to a temple or lens and a bridge member to a pair of lenses.
