Abstract
The clip includes a lens carrying member and a spectacle clamping member which are situated on opposite sides of a bifurcated support member. A single simple "c" shaped spring retains the members together, urges the clamping member toward its spectacle clamping position and urges the lens carrying member toward either an operative position, where the sunglass lenses intersect the line of sight, or an inoperative position, where the sunglass lens are remote from the line of sight.

A clip for mounting sunglass lenses on spectacles comprising support means, lens carrying means movably mounted relative to said support means, clamping means mounted for movement relative to said support means, between a clamping position proximate to said support means wherein the spectacles are clamped and a position remote from said support means and substantially "c" shaped spring means, said spring means at least partially defining a recess into which said support means, said lens carrying means and said clamping means are at least partially received, said spring means retaining said support means, said lens carrying means and said clamping means and providing sufficient force to bias said clamping means towards said clamping position and said lens carrying means toward either an operative or inoperative position.
A clip for mounting sunglass lenses on spectacles comprising support means, lens carrying means movably mounted relative to said support means, frame clamping means movably mounted relative to said support means, and substantially "c" shaped spring means, said spring means at least partially defining a recess into which said support means, said lens carrying means and said frame clamping means are at least partially received, said spring means retaining said support means, said lens carrying means and said frame clamping means and providing sufficient force to bias said clamping means towards a clamping position and said lens carrying means toward either an operative or inoperative position, said spring mean shaving first and second edges, said clamping means comprising first spring means edge retaining means, said carrying means comprising second spring means edge retaining means, said first spring means edge retaining means and said second spring means edge retaining means respectively retaining said first and second spring means edges and being situated, at least in part, within said spring means recess, said first spring means edge retaining means comprising a substantially cylindrical member having an elongated edge receiving recess.
A clip for mounting sunglass lenses on spectacles comprising support means, lens carrying means movably mounted relative to said support means, frame clamping means movably mounted relative to said support means, and substantially "c" shaped spring means, said spring means at least partially defining a recess into which said support means, said lens carrying means and said frame clamping means are at least partially received, said spring means retaining said support means, said lens carrying means and said frame clamping means and providing sufficient force to bias said clamping means towards a clamping position and said lens carrying means toward either an operative or inoperative position, said spring means has first and second edges, said clamping means comprises first spring means edge retaining means, said carrying means comprising second spring means edge retaining means, said first spring means edge retaining means and said second spring means edge retaining means respectively retaining said first and second spring means edges and being situated, at least in part, within said spring means recess, said second spring means edge retaining means comprising a member having an end and a spring means edge receiving recess spaced from said end.
A clip for mounting sunglass lenses on spectacles comprising support means, lens carrying means movably mounted relative to said support means, frame clamping means movably mounted relative to said support means, and substantially "c" clamped spring means, said spring means at least partially defining a recess into which said support means, said lens carrying means and said frame clamping means are at least partially received, said spring means retaining said support means, said lens carrying mans and said frame clamping means and providing sufficient force to bias said clamping means towards a clamping position and said lens carrying means toward either an operative or inoperative position, spring means having first and second edges, said clamping means comprising first spring means edge retaining means, said carrying means comprising second spring means edge retaining means, said first spring means edge retaining means and said second spring means edge retaining means respectively retaining said first and second spring means edges and being situated, at least in part, within said spring means recess, said first spring means edge retaining means comprising a substantially cylindrical member having an elongated edge receiving recess, said carrying means being movable relative to said support means between said operative and inoperative positions, wherein said member has an axis and wherein said first spring means edge exerts a force on said member directed along a line which is situated on one side of said axis, when said carrying means is in said operative position, and on the other side of the axis, when said carrying means is in said inoperative position.
