【Example】

 1 is a sectional view showing an embodiment of the eyeglass hinge of the present invention, FIG. 2 is a sectional view taken along the section line II-II of FIG. 1, and FIG. 3 is an exploded perspective view.

As shown in these drawings, the spectacle hinge 21 is a frame hinge member 24 fixed to the inner side of the spectacles (upper side in FIG. 1) at the tip of the armature 22 and a frame hinge member by a hinge shaft screw 26. The arm hinge member 25 assembled with 24, the elastic urging member 27 and the stop ring 28 integrally mounted on the arm hinge member 25, and the elastic urging member 27 and the stop ring 28 can be accommodated. And a case 29 fixed to the inner surface of the eyeglasses at the base end of the temple 23.

The frame hinge member 24 has its base bottom surface brazed and fixed to the end piece 22, and the case 29 also has its base bottom surface brazed and fixed to the inner side surface 23 a of the temple 23.

The frame hinge member 24 and the arm hinge member 25 are assembled so that their shaft holes 24a and 25a are aligned with each other, and a hinge shaft screw 26 is screwed therein so as to be rotatable within a predetermined angle range around this shaft screw.

The elastic urging member 27 is mounted integrally with the arm hinge member at the front end opposite to the shaft hole 25a in the longitudinal direction of the arm hinge member 25. The elastic urging member 27 is a set screw 31 screwed to the arm hinge member 25, and a coil spring 32 that is slidably fitted on the set screw 31 and is retained by a head 31a of the set screw 31. It consists of and.

Further, a stop ring 28 is externally fitted to the set screw 31 at a position where it comes into contact with the arm hinge member 25 in a clearance state with respect to the set screw 31. As shown in FIG. 3, the stop ring 28 is formed of a spring steel plate into a cylindrical shape, and has a slit 28a at one position in the circumferential direction, and is made of a cylindrical body that can be elastically expanded in diameter. In its natural state, its outer diameter is set to be larger than the inner diameter of a stop ring fitting portion 34, which will be described later, formed in the accommodation hole 30. Therefore, when the stop ring 28 is accommodated in the accommodating hole 30, the stop ring 28 is elastically pressed into the stop ring fitting portion 34.

The housing hole 30 of the case 29 includes a large diameter portion 30a and a small diameter portion 30b continuous with the large diameter portion 30a from the temple base end side, and the large diameter portion 30a faces the arm hinge member 25. And open. The large-diameter portion 30a uses the inner side surface 23a of the temple 23 on one side, and has a rectangular square hole 33 whose cross-sectional shape orthogonal to the longitudinal direction of the case 29 has long sides in the inner and outer directions of the spectacles (vertical direction in FIG. 2). And a stop ring fitting portion 34 which is formed so as to overlap a part of the square hole 33, has an arcuate surface in which the stop ring 28 is inscribed, and whose inner diameter is the distance between the opposing arcuate surfaces. Composed together.

The small diameter portion 30b has an inner diameter that allows the head portion 31a of the set screw 31 and the coil spring 32 to move freely.

A procedure for assembling the eyeglass hinge 21 using such parts and members will be described with reference to the sectional view shown in FIG. 4, the coil spring 32 and the stop ring 28 are attached to the set screw 31 in this order, and the threaded portion 31b (see FIG. 3) of the set screw 31 is provided in the arm hinge member 25 through a screw hole (not shown). Screw). Next, a case 29 with a temple is inserted so as to cover these stop ring 28 and elastic urging member 27. During this insertion operation, the stop ring 28 is diametrically outwardly sandwiching the slit 28a. From above, the stop ring 28 is inserted into the large diameter portion 30a while keeping the diameter of the stop ring 28 reduced. The stop ring 28 is preferably inserted with its slit 28a facing the temple 23 or facing in the opposite direction.

By being assembled in this way, as shown in FIG. 1, the stop ring 28 elastically expands in the large-diameter portion 30a and becomes in contact with the stop-ring fitting portion 34. It is fitted and fixed. By inserting the case 29 into the arm hinge member 25 to a predetermined position in this manner, the temple 23 and the case 29 are correctly assembled to the arm hinge member 25 via the stop ring 28.

According to the eyeglass hinge 21 of the present invention, when the arm hinge member 25 and the temple 23 are assembled, the case 29 is put on the arm hinge member 25 to which the elastic biasing member 27 and the stop ring 28 are attached. It can be achieved simply by inserting into.

In the eyeglass hinge 21 assembled in this way, the elastic biasing member 27 serves to elastically control the expansion of the temple 23 outward of the glasses. That is, in the structure of the eyeglass hinge 21 of the present invention, as shown in the sectional view of FIG. 5, even when the pressure of the arrow A is applied to the eyeglass frame 1 from the outer side of the eyeglass, the coil spring 32 is actuated. Since the temple 23 elastically expands outwardly of the eyeglasses, the eyeglass frame is not deformed and the contact point P between the tip of the armature 22 and the base end of the temple 23 is not damaged.

The elastic force of the elastic biasing member 27 can be adjusted by adjusting the screwing length of the screw portion 31 b of the set screw 31.

Even after the arm hinge member 25 and the temple 23 are assembled, if the case 29 is pulled with a force larger than the pressure contact force of the stop ring fitting portion 34 due to the elastic force of the stop ring 28, the assembly is completed. Since it can be released, as described above, the screwing length of the screw portion 31b of the set screw 31 can be adjusted.
