ネが位置ズレするなど、安定性が損われる。2. Description of the Related Art Eyeglasses are provided with vines on both sides of a front portion so that they can be folded. That is, both vines are opened when the glasses are worn on the face, and both folds are closed when the glasses are removed from the face. By the way, the hinge that connects the temples of the glasses is very small, and it takes a great burden to support a long temple. Therefore, the sliding surface is worn due to bending, the vine is loosened, and the glasses worn are misaligned, which impairs stability.

る。Particularly, in recent years, since a spectacle frame is preferably made of a material that is light and has excellent spring properties, a titanium material is often used as a material satisfying this requirement. In many cases, the hinge is also made of titanium, and the wear of the sliding surface is particularly remarkable in this titanium hinge. And with the titanium hinge, the sliding surface that has been cut is a fine uneven surface like a casting, that is, it is not a smooth surface, so creases are generated during the folding operation of the vine, and a smooth folding operation can be performed. Absent. That is, smooth sliding cannot be obtained.

を介して折畳むことが出来る。Therefore, in the prior art, smooth sliding is provided by interposing a washer on the sliding surface of this small hinge,
Measures are taken to prevent wear. FIG. 6 is an external view showing a hinge of an eyeglass frame for folding a vine that has been conventionally used. As shown in the figure, the hinge is a butterfly piece.
(A) and (b) are connected by shaft screws (c) so that they can be bent.One of the butterfly pieces (b) has its joint surface (d) brazed to the end piece, and the other The joint surface (d) of the butterfly piece (a) is brazed to the vine. Therefore, the vine can be folded via the hinge.

施例を図面に基づいて詳細に説明する。On the other hand, the folding operation of the temple of the spectacle frame is not necessarily limited to the case where the hinge is used, and it is also possible to directly form a joint piece at the temple end and connect it to the joint piece provided at the front portion. Therefore, in the present invention, it is possible to attach a bush with a washer to the top of this joint in the same manner as the hinge top. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

ることで円盤状のワッシャが形成される。FIG. 2 shows a state in which the bush 1 is fitted in the shaft hole of the top 5. As shown in the figure, the cylinder 2 fits in the shaft hole, but the washer 3 having a large outer diameter abuts the end surface 6a of the top 5, and the tip portion 7 of the cylinder 2 projects from the shaft hole. Therefore, the protruding tip portion 7 is processed to form a washer, and the tool 8 as shown in FIG.
Is pressed against the tip portion 7 of the cylinder 2. The tip of the tool 8 has a conical shape, and if the conical portion 9 is pressed into the cylindrical hole and is fitted therein, the cylindrical tip portion 7 is expanded and the tool 8 is further pressed to form a disk-shaped washer. To be done.

間を残すことなく該端面6bと密着する。A flat surface 10 is formed around the conical portion 9 of the tool 8, and when the flat surface 10 is spread by the conical portion 9, the flat surface 10 hits and is pressed, and as a result, it is crushed into a washer. In this case, the C surface 11 or the R surface is formed at both ends of the shaft hole of the top 5 and at the corners with the end surfaces 6a and 6b. By forming the C surface 11 or the R surface, the tool 8
The washer formed by being pressed by is closely attached to the end surface 6b without leaving a gap between the washer and the end surface 6b.

In this way, the bush 1 is fixed to one of the tops 5, that is, it does not come off during the assembly work. The washers 3 and 12 of the bush 1 are the sliding surfaces 14 of the other butterfly piece,
If the butterfly piece bends due to the folding operation of the crane, smooth sliding occurs between the surfaces of the washers 3 and 12 and the top sliding surfaces 14 and 14 of the other butterfly pieces. To do.

のような効果を得ることが出来る。The present invention includes not only the hinge described in the embodiment but also a joint in which a top is directly provided at the temple end. In the case of the joint piece, a bush with a washer is fitted in the shaft hole like the hinge piece, and the cylinder protruding from the shaft hole is pushed open to form the washer. That is, washers are formed in close contact with both end faces, and the joint piece is connected to the joint piece on the front portion side via a shaft screw. As described above, the joint and hinge of the spectacle frame according to the present invention have the bush with a washer fitted in the shaft hole of one of the tops, and the following effects can be obtained.

得る。In the joint and hinge of the eyeglass frame according to the present invention, since the bush with washer is attached to the shaft hole of one of the tops, the cylinder of the bush is fitted into the shaft hole and the washers are provided at both ends. It will not form and come off. Therefore, the joint and the hinge can be assembled smoothly, and the efficiency of the assembly work of the eyeglass frame can be improved. Then, as compared with the conventional case of handling a small washer, the workability is improved by fitting the cylinder of the bush into the shaft hole and molding the washer on the opposite side. A washer is placed on the sliding surface of the top to prevent abrasion of the sliding surface even if the joint or hinge bends as the fold operation of the vine is performed. The operation can be performed smoothly.
