[Industrial applications]

 The present invention relates to a temple hinge structure.

[0002]

[Prior art]

 A conventional hinge structure in a temple in which a connecting member is pivotally attached to the front end of a temple body is usually brazed with a hinge piece at the front end of the temple body and a rear end of the connecting member, and both hinge pieces are connected. They were in a meshed state and were connected by a pivot.

[0003]

[Problems to be solved by the device]

 As described above, the conventional hinge structure has a problem in that the manufacturing efficiency of the temple is poor because the brazing process that requires skill and is time-consuming is essential. Also, when targeting a thin temple, a special small hinge piece with a small vertical width must be manufactured in accordance with it, and the brazing area is small, which makes brazing difficult. was there. In addition, since the bearing piece is thin, the base part of the bearing piece is easily broken, and the hinge does not have sufficient strength. In recent years, materials such as titanium alloys, aluminum, and superelastic alloys that require brazing in a special atmosphere or require special coating before brazing have been adopted as materials for eyeglasses. However, there is a problem that the brazing requires high technology. An object of the present invention is to provide a temple hinge structure that eliminates the brazing process and solves such a problem.

[0004]

[Problems to be solved by the device]

 In order to solve the above problems, the present invention adopts the following means. The hinge structure of the temple according to the present invention (hereinafter referred to as the hinge structure) is a temple in which a connecting member is pivotally attached to the front end of the temple body, and the front end portion of the temple body is formed in an annular shape and the rear end of the connecting member is formed. The part is also formed in an annular shape, and both annular parts are stacked vertically with their insertion holes aligned with each other. The upper and lower pieces are bent so as to face each other at the upper and lower sides of the side pieces, and the insertion hole and the core of the annular portion are formed on the upper and lower pieces. The upper and lower ends of the pivot shaft, which is housed in the groove formed between the upper piece and the lower piece of the U-shaped box member with the axial holes provided together, and through which both shaft holes and both insertion holes are inserted are called the upper piece. The temples can be bent by holding them on each of the lower pieces. Further, the front end portion of the temple main body and the rear end portion of the connecting member are brought into contact with the inner surface portion of the side piece of the box member so that the temple is held in the expanded state. .

In addition to the hinge structure according to the present invention, in a temple in which a connecting member is pivotally attached to the front end of the temple body, either one of the front end portion of the temple body or the rear end portion of the connecting member is attached. It is formed in a bifurcated shape, and the end portions of both branch parts are annular parts, and the other of the front end part of the temple body or the rear end part of the connecting member is an annular part inserted between the upper and lower annular parts. Then, the stacked portions of the annular portions are formed by bending the upper piece and the lower piece so as to face each other above and below the side piece, and align the insertion hole and the hole center of the annular portion with the upper piece and the lower piece. Of the U-shaped box member provided with a shaft hole, and is housed in the groove formed between the upper piece and the lower piece. The temples can be bent by holding them on each side. Further, the front end portion of the temple body and the rear end portion of the connecting member are brought into contact with the inner surface portion of the side piece of the box member so that the temple is held in the expanded state. is there.

In each of the hinge structures, it is preferable to use a connecting screw as a pivot, and in that case, the connecting screw is inserted through each annular portion from one shaft hole side of the box member toward the other shaft hole. Insert it through the hole, and screw the threaded part of the connecting screw into the other shaft hole to tighten it.

Further, in each of the above hinge structures, a washer piece having a through hole with a common hole center may be arranged between the adjacent annular portions. In this case, the washer piece is preferably integrally provided on the inner surface of the side piece of the box member.

Further, in each of the above-mentioned hinge structures, each annular portion of the front end portion of the temple main body and the rear end portion of the connecting member has, for example, a through hole punched at the center of a disc-shaped portion or a wire rod formed into an annular shape. It is formed by bending.

[0009]

[Action]

 However, in the hinge structure according to the present invention, since the temple body 2 and the connecting member 3 are connected by the pivot 24 using the box member 16, the temple can be bent, and when the temple is in the unfolded state. The front end portion 2a of the temple main body 2 and the rear end portion 3a of the connecting portion 3 are brought into contact with the inner surface portion 30 of the side piece 17 of the box member 16, respectively, and the expanded state is maintained.

When the connecting screw is used as the pivot, when opening and closing of the temple becomes unsatisfactory, the opening and closing hardness can be easily returned to the required state by adjusting the tightening degree of the connecting screw.

The washer piece 31 interposed between the adjacent annular portions prevents the annular portions from rubbing against each other. If the temple body and the connecting member are made of titanium, the contact surfaces may become rough due to the friction between the annular parts, and the smoothness of temple opening and closing may be impaired. , It is solved by interposing a washer piece in this way.
