12を有している。First, the structure of a twisted eyeglass temple according to a first embodiment of the present invention will be described with reference to FIGS. In the figure, what is indicated by reference numeral 1 is a temple hinged to each of the left and right ends J and E of the front frame F of the plastic glasses. The temple 1 is a rod-shaped member formed of a thermoplastic synthetic resin (in this embodiment, an acetate resin material is used) in a small width. The proximal end of the rod-shaped temple 1 is formed to be thin in the vertical direction, and has a pivotal support portion 11 in which a shaft support hole 11a is bored in the vertical direction. Then, the pivot portion 11 is fitted between the U-shaped piece members B of the chi E. The hinge screw S is inserted into the screw holes B1.
The temple 1 is hinged to the left and right ends of the front frame F so as to be freely foldable by being inserted into B1 and the shaft support hole 11a of the pivot portion 11. The other end side of the temple 1 is an ear hook portion bent into a shape that can be hooked on the ear of the spectacle wearer.

It has become. Due to this torsion, the proximal end side of the small-width temple 1 with respect to the torsion portion is substantially orthogonal to the shaft support hole 11a of the pivot portion 11, and the distal end side of the torsion portion is smaller than the torsion support portion. A side contact surface 13 is formed substantially parallel to the hole 11a.

優れている。In the twisted eyeglass temple 1 constructed in such a manner as to be twisted, the twisted winding portion P of the twisted portion provides a decorative accent that is different from the decoration by conventional plating or coining. Since the design can be improved and the design is improved, a small-width side contact surface 13 that is substantially parallel to the side of the wearer of the spectacles is formed inside the ear hook 12 of the temple 1. The temporal portion fits on the contact surface 13 so that the wearing comfort of the glasses is good. Further, in the temple 1, since the core metal 2 is inserted into the temple 1 made of a thermoplastic synthetic resin, the temple 1 is stronger and more durable than a normal plastic temple. Furthermore, since the base end side of the temple 1 is formed to be thin in the up-down direction, it is possible to secure a good side view when wearing spectacles, and it is also excellent in safety when driving a car or the like.

The eyeglass temple 1 is further twisted by 180 ° from the temple 1 of the first embodiment twisted by 90 °. Thereby, a spiral torsion part P is formed at the torsion part of the temple 1, and the design is further improved. In the present embodiment, the temple 1 is twisted 270 ° (90 ° × 3) with respect to the base end side, but forms a temporal contact surface 13 substantially parallel to the temporal region of the spectacle wearer. The angle can be freely set to a possible twist angle, that is, an angle that is an odd multiple of 90 °.

And the lower mold Mb are retracted up and down to make the temple mold 1 'of FIG.
Is removed from the mold to obtain a temple mold 1 'having a small width (see FIG. 8). Thereafter, a metal core 2 to which the pivot 11 of the metal piece having the shaft support hole 11a is connected is prepared, and the core of the metal core 2 is inserted into the core hole 14 'of the temple mold 1' and joined. At the base end side of the mold 1 ', a pivot portion 11 of a metal piece having a pivot hole 11a is provided. Then, when the ear hook forming portion 12 'on the distal end side of the temple mold 1' into which the core metal 2 is inserted is bent into a required shape to form the ear hook portion 12, the temple mold 1 shown in FIG. 'Is obtained.

Is held by the chucks CC in a cooled state (see FIG. 10). In this gripping state, only the intermediate portion of the temple mold 1 'is heated and softened by the heating means H. Before the softened portion of the temple mold 1' is hardened, the rear chuck C is moved to the position shown in FIG. Rotate about 90 ° in the direction of the arrow to twist. Then, a temporal contact surface 13 is formed on the distal end side from the intermediate portion, and a twisted winding portion P having a variety of appearances is formed on the torsion portion, as shown in FIG. Such a twisted eyeglass temple 1 is obtained.
