Description

  The present invention relates to a temple for a spectacle frame, and more particularly to a temple for applying a biasing force to a face.

  There are various types of spectacle frames, for example, a pair of annular rims, a bridge that connects between the inner edges of both rims, and an outer edge of each rim that is rotatably connected via a spring hinge. A spectacle frame having a temple is known. The spectacle frame described in Patent Document 1 includes a spring hinge that connects the temple and the armor, and when the temple is opened, the tip of the leaf spring provided on the temple at a predetermined position contacts the end of the armor. It has a structure that touches.

  When the temple is further opened from a predetermined position, the leaf spring is bent along with the opening, and a restoring force is exerted to push the temple back to the predetermined position. Therefore, when this spectacle frame is worn, it is possible to apply a biasing force to the face by adjusting the temple opening so that it opens slightly from the predetermined position. can do.

However, the above-described spectacle frame has a problem in that the structure of the spring hinge is complicated, so that it takes time and effort to manufacture and assemble, and the cost increases. In addition, in order to maintain the initial performance for a long time, there is a problem that requires regular maintenance. Furthermore, the spring hinge has a problem that the temple shape becomes large and a smart design cannot be achieved.
