DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temple mounting structure for an eyeglass frame.

[0002]

2. Description of the Related Art In a conventional eyeglass frame, a temple is generally rotatably mounted via a hinge so as to be fixed to a lens frame. However, since a small machine screw is used as the pivot for the hinge,
There is a problem that the machine screw is easily loosened and easily damaged. Various temple mounting structures have been proposed in place of hinges, but many of them require time and effort for mounting and dismounting, and many have complicated and large structures.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems and to provide a temple mounting structure for an eyeglass frame which can be easily mounted and removed from the armor and can be made compact. Aim.

[0004]

In order to achieve the above object, a temple mounting structure according to the present invention is provided with a pair of shaft support pieces provided at an end of an armor with a holding space portion interposed therebetween. The pivot is fixed to the front end of the connecting member connected to the tip of the temple, and a pair of holding pieces are provided which are inserted into the holding space and hold the pivot. A male screw portion is provided on the outer periphery of the rear end portion, and an engagement groove having an arc-shaped cross section along the outer peripheral surface of the pivot is provided on the opposing surfaces of the pair of holding pieces, and the temple slides. A female screw portion to be screwed into the male screw is provided on a cylindrical tightening cover that is freely fitted, and the tightening cover is fitted on the connecting member, and is rotated and tightened, whereby the pair of tightening covers is used. Hold the holding piece of Kigakarigomizo is configured to engage the pressed contact state to the pivot.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded view of parts constituting a temple mounting structure according to the present invention.
Shows a state in which the temple is attached to the armor.
The temple mounting structure includes an armor 1 fixed to the outer portion of the lens frame 20 (see FIG. 2) by brazing or other joining means, and a connecting member 3 fixedly connected to the tip of a temple 2 made of a wire. And a cylindrical tightening cover 4 which is slidably fitted to the temple 2 and is fitted to and held by the connecting member 3.

A pair of shaft support pieces 5, 5 are provided at one end of armor 1.
Are provided integrally with the sandwiching space 6 interposed therebetween, and the pivot 7 is fixedly supported by the biaxial support pieces 5 and 5. The connecting member 3 has a front half portion of a short columnar body divided in half by a split groove 8 extending in the axial direction. The front end portion of the connecting member 3 is inserted into the holding space 6 of the armor 1 to pinch the pivot 7 from both sides. A pair of holding pieces 9, 9 are formed, and engaging grooves 10, 10 having an arc-shaped cross section along the outer peripheral surface of the pivot 7 are provided on the opposing surfaces of the holding pieces 9, 9. Also, the connecting member 3
An external thread 11 is provided on the outer periphery of the rear end. On the other hand, the fastening cover 4 is provided on the inner peripheral surface with the male screw portion 1 of the connecting member 3.
A female threaded portion 12 screwed to 1 is provided, and the rear portion is formed in a tapered cylindrical body whose tapered portion is narrowed. A knurl 13 extending in the axial direction is provided on the outer peripheral surface of the tightening cover 4 to prevent slippage of fingers during a rotation operation. The decorative function can be enhanced by changing the external shape of the fastening cover 4. The corner 9a of one of the holding pieces 9 of the connecting member 3 functions as a stopper for restricting outward expansion when the temple 2 is opened. Furthermore, the opposing surfaces 9b, 9b of the tip portions of the two holding pieces 9, 9 are slightly inclined outwardly, so that when they are inserted into the holding space 6, the pivotal connection 7 between the two holding pieces 9, 9 can be easily formed. ,
In addition, they are guided securely and pinched.

[0007] To attach the temple 2 to the armor 1, the clamping pieces 4 of the connecting member 3 are detached from the connecting member 3 and held on the temple 2 in a sliding state. Is inserted into the holding space 6 of the armor 1 and pushed in while guiding the pivot 7 between the opposing surfaces 9b, 9b of the holding pieces 9, 9, the holding pieces 9, 9 are pushed and expanded to both sides. The two engagement grooves 10, 10 are engaged with the pivot 7, and the connecting member 3
However, the temple 2 is thus mounted rotatably about the pivot 7. Next, when the fastening cover 4 is fitted to the connecting member 3 and rotated, and the female screw portion 12 is screwed into the male screw portion 11 and tightened, the clamping cover 4 causes the two holding pieces 9 and 9 to approach each other. Held, both engagement grooves 1
The inner surfaces of 0 and 10 are pressed against the outer peripheral surface of the pivot 7 so that the temple 2 is attached to the pivot 7 so as to be rotatable around the pivot 7 and the connecting member 3 is unexpectedly curled 1. There is no danger of dropping off, and the installation is completed.

When the temple 2 is to be removed for repair or replacement, the connecting member 3 can be easily removed by pulling the connecting member 3 against the armor 1 with the covering cover 4 loosened.

[0009]

As described above, according to the present invention,
Since the temple can be easily attached to and detached from the armor, it is convenient for repairing or replacing the temple. Moreover, since the connecting member is covered with the covering cover, the entire mounting portion can be made compact. Further, by changing the appearance shape of the covering cover, a decorative function can be provided.
