In a spectacle frame having a front rim with two opposite end portions and, at each said end portion, a respective temple member connected to said front rim by a corresponding hinge for pivotal movement about a corresponding pivot axis between an open position where said temple member extend rearwardly with respect to said front rim for use and a closed position where said temple member extends along said front rim for storage, the improvement wherein said hinge comprises: an elastic wire member having a pair of arms extending substantially longitudinally of said temple member and attached to said temple member for movement therewith about said pivot axis between two positions respectively corresponding to said open position and said closed position of said temple member, each arm having a shaft portion bent therefrom along said pivot axis, and a bearing member provided on the corresponding end portion of said front rim, said bearing member including bearing means formed along said pivot axis to receive said shaft portion of each arm, and projection means arranged in a path of movement of at least one of said arms between said two positions for abutting said one arm and elastically deforming said one arm along said pivot axis during movement of said one arm from each of said two positions to the other.
Claim 3
Dependent Claim
84 words
The improvement of claim 1, wherein said projection means includes a first slope surface arranged for contacting with said one arm to elastically deform the same in a predetermined direction along said pivot axis during movement of said one arm from one of said two positions to the other, and a second slope surface arranged for contacting with said one arm to elastically deform the same in said predetermined direction during movement of said one arm from said other position to said one position.
Claim 4
Dependent Claim
24 words
The improvement of claim 1, wherein each said shaft portion of said elastic wire member is bent in an opposite direction from the other.
Claim 5
Dependent Claim
76 words
The improvement of claim 1, wherein said bearing member has a pair of L-shaped recesses each including a pair of leg portions into one of which a corresponding one of said arms inserts when said temple member is in said open position, and into the other of which said corresponding arm inserts when said temple member is in said closed position, and wherein said bearing means has portions positioned at respective corners of said L-shaped recesses.
Claim 6
Dependent Claim
30 words
The improvement of claim 4, wherein said bearing member further includes wall means along an outer periphery of each of said L-shaped recesses for limiting movement of the corresponding arms.
