Description

[Detailed explanation of the invention] In conventionally known glasses with temples attached with hinges, the screws on the hinge become loose, and even if you try to put on your glasses by holding one temple, the other temple will fall inward, causing one of the temples to fall inward. It may not be possible to hang just by holding the vine.

Also, the hinge screws may loosen and fall off without you even realizing it.

This invention allows the vine to open and close using a mechanism separate from the hinge.
However, it is designed so that it can be maintained at any desired opening degree. Next, embodiments of the present invention will be described.

A groove 2 is provided on the inner surface from the front end to the rear end of the sheath body 1. Arc-shaped grooves 3, 3 are provided on both sides of the groove in the rear half of the sheath body 1 to form a hole with a circular cross section. An arc-shaped recess 4 is provided in the section, a deep notch 5 is provided in the center of the recess 4, and a hole 15 having a width corresponding to the diameter of the hole 15 having a circular cross section in the sheath body is provided in the rear half of the main body 6 which is inserted into the groove 2 of the sheath body 1. A long hole 7 is provided, projections 8, 8 are provided on the side surface of the front end of the main body 6, a hole 9 is provided behind the hole 9, the main body 6 is inserted into the groove 2 of the sheath body 1, and a coil spring 10 is inserted into the long hole 7 of the main body. The straight part of the receiving piece 12 having one end formed in a bifurcated arc shape is fixed to the lower part of the armor 11, and this arc-shaped curved part 1
Hook the protrusions 8, 8 on the front end of the main body 6 to the spring 1.
This invention relates to a temple hinge device for eyeglasses, which is characterized in that the sheath body 1 is fixed to the inner surface of the temple 14 while the sheath body 1 is kept in tension. The hole 9 is a hole for inserting the tip of a hook for pulling out the main body 6.

In the present invention, the arc-shaped curved portion 13 at the tip of the receiving piece 12 attached to the armor engages with the arc-shaped recess 4 at the front end of the sheath body 1, and the protrusion 8 provided at the front end of the main body 6,
8 is hooked onto the arcuate curved portions 13, 13 of the receiving piece 12. Also, a coil spring 10 fitted into the elongated hole 7 of the main body 6
When the main body 6 hits the end face of the groove 2 of the sheath body 1 and an attempt is made to pull the main body 6 out of the sheath body 1, the spring 10 contracts and the main body 6 tends to be retracted. Therefore, the protrusions 8, 8 provided on the main body 1 are supported by the curved parts 13, 13 of the receiving piece 12, and since these protrusions are retracted by the coil spring 9, the protrusions 8, 8 are supported by the curved parts 13, 13 of the receiving piece 12. Part 13,
13, and a large frictional force is generated between the engagement surfaces of the two. Therefore, when the temple is closed or opened, the opening degree of the temple is reliably maintained. In this way, the opening angle of the temples is reliably maintained, so if you open both temples and hold one temple to put on your glasses, you can easily hang the glasses with the other temple open.

Furthermore, since no screws are used in the opening/closing part of the vine, there is no chance of the vine coming off due to screws falling off, which is the case with hinge-based opening/closing mechanisms.
