Abstract
Abstract A hinge portion of a spectacle frame of generally lightweight construction is provided with essentially thin and limited vision obstructing side pieces. The hinge comprises a cam bearing flat metallic component fixedly secured to the respective side end of the front piece of the frame, and a subassembly comprising a ball-shaped cam follower and a spring urging the follower against the cam, the follower and the spring being guidedly housed in an axial bore provided in an elongated metallic body secured to a metallic side piece or to a metallic core of a lightweight side piece, forming the fore and hinge portion of the side piece and a part of an unitary metallic external structure therefor.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
189 words
A spectacle frame conprising a front piece having respectively spaced side end portions; a cam element rigidly connected to each one of said side end portions of said front piece and with said cam element having a cam surface; a connecting element for each side end portion having a substantially flat end portion; means for mounting said connecting elements on said side end portions for movement between a closed and an open position; cam follower means accommodated in each of said connecting elements and including at least one cam follower member and means for urging said cam follower member into contact, with said cam surface; and side pieces, each side piece having a substantially flat end portion rigidly connecting one side piece to and overlying a respective one of said connecting elements at only one side thereof which faces away from said front piece when the respective connecting element is in said closed position thereof, whereby said end portion of each of said side pieces at least partly conceals said respective connecting element from view in a direction normal to and facing said one side of said connecting element.
Claim 2
Dependent Claim
189 words
A spectacle frame conprising a front piece having respectively spaced side end portions; a cam element rigidly connected to each one of said side end portions of said front piece and with said cam element having a cam surface; a connecting element for each side end portion having a substantially flat end portion; means for mounting said connecting elements on said side end portions for movement between a closed and an open position; cam follower means accommodated in each of said connecting elements and including at least one cam follower member and means for urging said cam follower member into contact, with said cam surface; and side pieces, each side piece having a substantially flat end portion rigidly connecting one side piece to and overlying a respective one of said connecting elements at only one side thereof which faces away from said front piece when the respective connecting element is in said closed position thereof, whereby said end portion of each of said side pieces at least partly conceals said respective connecting element from view in a direction normal to and facing said one side of said connecting element.
Claim 3
Dependent Claim
