ABSTRACT:
A spectacle frame has temple members each of which can be turned around a corresponding pivot axis between a first position where the temple member is opened with respect to a front rim for use and a second position where the temple member is bent toward the front rim for storage. The frame includes a pair of hinges for connecting the corresponding temple members to said front rim. Each hinge comprises an elastic wire member and a bearing member. The wire member has a pair of arms extending from one end of the corresponding temple member substantially in parallel with a longitudinal direction of the temple member, and a pair of shaft portions each bent from a corresponding arm along the corresponding pivot axis. The bearing member, which is provided on one end of the front rim, includes a bearing portion formed along the pivot axis to receive the pair of shaft portions of the wire member, and at least one projection arranged in the path of movement of at least one of the arms of the wire member between two positions corresponding to the first and second positions of the temple member. The projection is configured to elastically deform the arm along the pivot axis during movement of the arm between the aforementioned two positions.
