Abstract

PROBLEM TO BE SOLVED: To constitute a temple connecting structure utilizing the restitutive force of an elastic spring member with simplicity, thereby improving the assembly work thereof, reducing the cost of manufacture and preventing an enormous increase in the size of a wraparound endpiece in order to build the spring member therein. SOLUTION: Connecting pieces 2 and 3 projectingly disposed at the top and bottom of the wraparound endpiece 1 are provided with introducing grooves 4 and 5 and further the deep portions of the introducing grooves are provided with shaft holes 6 and 7. Circular shafts 10 and 11 disposed in a coupling 9 at the top end of the temple 8 are inserted into the shaft holes 6 and 7 through the introducing grooves 4 and 5. At this time, the coupling 9 thrusts the elastic spring 12 integrated with the wraparound endpiece 1 disposed at the wraparound endpiece 1 and the dislodging and shaking of the temple 8 are prevented by the restitutive force of the spring 12.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temple connecting structure for spectacles utilizing a restoring action of an elastic spring portion formed integrally with a yoke.

[0002]

2. Description of the Related Art Eyeglasses utilizing the restoring action of an elastic spring member have a structure in which a conventional spring member is manufactured and assembled as a separate part, and an example thereof is shown in FIG. Proposed.

[0003]

However, this is because the use of the spring member as a separate part increases the cost due to assembly, such as manufacturing, brazing for fixing the spring member, and screwing work. Since a space for incorporating the members is required, there is a problem that the size of the yoke is enlarged.

[0004]

In order to solve the above-mentioned problems, the present invention employs the following means. That is, the temple connecting structure of the glasses according to the present invention is such that the connecting portion of the temple is inserted between the connecting pieces protruding up and down of the yoke, and the connecting portion is connected to the upper and lower connecting pieces by a pivot. However, it is characterized in that the temple is prevented from dropping and rattling by pressing an elastic spring portion formed integrally with the yoroi and restoring action of the elastic spring portion.

[0025]

The present invention has the following excellent effects. (1) By adopting a configuration in which the elastic spring portion that applies a biasing force to the temple is manufactured as a single piece, improvement in the efficiency of assembling and manufacturing eyeglasses and reduction in manufacturing cost can be expected. (2) Since the elastic spring portion for applying the urging force to the temple is manufactured as a single piece, there is no need for a concave portion or a space for screwing, which is necessary when the elastic spring material is formed separately. It is possible to prevent enlargement of the yoroi. (3) The temple can be stably opened and closed without rattling even when the pivot formed as a screw, a pin, a shaft, or the like is slightly worn by the biasing force due to the restoring action of the elastic spring portion. (4) When the temple in the deployed state is configured to be elastically further expanded outward, excellent fit to the temporal region can be obtained when wearing glasses.
