As shown in FIG. 3, the screwless hinge mechanism of the present embodiment comprises a pair of upper and lower bearing members 1.1 fixed to the end of the end piece E on the take-out side, and a pair of these bearing members. And a shaft member 2 pivotally supported between the members 1.1.

That is, each bearing member 1 of the present embodiment is formed in a cover-like cap shape, and is brazed and joined to the end of the end piece E on the take-out side so as to face each other. A cylindrical shaft member 2 is pivotally supported between the upper and lower pair of bearing members 1.1 so that the shaft T can rotate freely. The temple T is orthogonal to the shaft member 2 between the pair of bearing members 1.1. It is joined by brazing.

In the screwless hinge mechanism of this embodiment, the opening and closing operation of the temple T is performed by rotating the shaft member 2 between the bearing members 1 and 1, as shown in FIG. When the base end t of the temple T contacts the end piece E, the temple T stops at the maximum spread position.

As described above, in the screwless hinge mechanism of the present embodiment, since the temple T is directly fixed to the shaft member 2 pivotally supported between the pair of upper and lower bearing members 1.1, the conventional structure is employed. As described above, it is not necessary to use a hinge screw serving as a hinge shaft, and it is not necessary to carve a female screw in the bearing member 1. Therefore, the hinge mechanism can be made extremely slim and simple, which can greatly contribute to weight reduction and slimness of the entire eyeglass frame, and does not bother with the loosening of the hinge screw due to vibration or the like.

Further, since the maximum expansion of the temple T can be reliably restricted by bringing the base end t of the temple T into contact with the end piece E, it is necessary to add another temple expansion restricting means to the hinge mechanism. In this respect, the hinge mechanism can be simplified in this respect as well.

Second Embodiment A screwless hinge mechanism according to a second embodiment shown in FIGS. 5 and 6 comprises a pair of upper and lower bearing members 1.1 fixed to a temple T, and a pair of these bearing members. 1 and a shaft member 2 pivotally supported between the two.

A cylindrical shaft member 2 is rotatably supported between the pair of upper and lower bearing members 1.1 so that the end piece E can be taken out by the shaft member 2 between the pair of bearing members 1.1. Are brazed and joined in an orthogonal state.

In the screwless hinge mechanism of this embodiment, the opening and closing operation of the temple T is performed by the rotation of the bearing member 1.1 with respect to the shaft member 2 fixed to the end piece E, and When the base end t of the T contacts the end piece E, the temple T stops at the maximum spread position.

As described above, in the screwless hinge mechanism according to the present embodiment, the temple T is directly fixed to the pair of upper and lower bearing members 1.1 for pivotally supporting the shaft member 2 fixed to the end piece E. Therefore, similarly to the above-described first embodiment, there is no need to use a hinge screw serving as a hinge shaft, and it is not necessary to engrave a female screw in the bearing member 1. Therefore, the hinge mechanism can be made extremely slim and simple, greatly contributing to the weight reduction and slimness of the entire eyeglass frame, and the hinge screw is not bothered by loosening due to vibration or the like.

Further, since the maximum expansion of the temple T can be reliably restricted by bringing the base end t of the temple T into contact with the end piece E, it is necessary to add another temple expansion restriction means to the hinge mechanism. In this respect, the hinge mechanism can be simplified in this respect as well.

Embodiments which are specific examples of the present invention are generally configured as described above. However, the present invention is not limited to these embodiments, and various embodiments are described within the scope of the claims. Can be changed.
