Description

[Detailed description of the invention] (Industrial application field) The present invention includes a front temple and a rear temple, and allows for easy replacement of the rear temple and adjustment of the length of the temple after the replacement, as well as a good appearance. This invention relates to a temple for glasses that has good elasticity and excellent stability.

(Prior Art) The ear hooks of conventional eyeglasses were generally of a half-hook type as shown in Fig. 1;
When playing sports that involve strenuous movements, such as golf or tennis, or performing various types of work that involve strenuous movements, there are inconveniences such as glasses slipping off or falling off during the activity. In order to avoid such drawbacks as much as possible, glasses with a cable-type ear hook as shown in FIG. 2 have been conveniently used. However, having two types of glasses with different ear hooks was not only extremely uneconomical, but also
It was also inconvenient to have to carry unused glasses.

As eyeglass temples that attempt to solve some of these problems, those disclosed in Japanese Utility Model Application Publications No. 138852/1982 and No. 82223/1988 have been proposed.

The former (Utility Model Application No. 49-138852) is shown in Figure 10a,
As shown in b, after the front end engagement piece d of the rear temple c is slidably inserted into the square hole-shaped insertion hole b of the square tube-shaped front temple a, and the length of the temple is adjusted as desired. By tightening the rear end portion of the front temple A, which has been split into two, with a set screw e, the front temple A and the rear temple C can be integrated.

The latter (Utility Model Application No. 59-82223) is shown in Figure 11a,
As shown in b, the rear joint piece i of the front temple h can be slidably inserted into the square insertion hole g provided in the front part of the rear temple f, and the rear end portion of the front temple h A screw fitting groove k with a flat groove bottom j is provided in the longitudinal center portion of the lower surface, and a set screw l is installed from the lower surface of the rear temple f, and the rear end joint piece of the front temple is fitted with a set screw l. After adjusting the amount of insertion of i, tighten the set screw l to open the screw fitting groove k.
The front vine h and the rear vine f were integrated.

(Problem to be solved by the invention) However, the former and latter glasses temples had the following problems in common.

Although the length of the temple is fixed by tightening the set screw, the inner surface of the insertion hole and the outer surface of the joint piece are formed to be slidable in surface contact.

Therefore, even if the set screw is tightened to adjust the length of the temple, even if the set screw loosens a little, the tip of the threaded part will not come into contact with the outer surface of the joint piece, and the insertion length of the joint piece will immediately change. There was a problem that led to variable instability.

When wearing glasses, the temples are pushed outward, so if you adjust the length of the temples to a longer one, that is, if you reduce the amount of insertion of the joining piece, the joint between the front temple and the rear temple will be reduced. There was a problem where parts were easily unstable due to their strength.

Although the length of the vine is adjusted by adjusting the amount of insertion of the engaging piece into the square insertion hole, there were no marks or other markings provided to guide the length adjustment. There were problems in that it took time to match the lengths of the left and right temples, and that the glasses could not be adjusted correctly.

The object of the present invention is to provide a temple for glasses that can solve the above-mentioned problems and also allows for diversification of the temple design, thereby contributing to improving the fashionability of the glasses.

(Means for Solving the Problems) In order to solve the above problems, the present invention employs the following means.

That is, the temple of glasses 1 according to the present invention includes a front temple 2 and a rear temple 3, and one of the front temple 2 and the rear temple 3 is the front temple 2 and the rear temple 3.
It has an insertion part 9 extending in the length direction of the front temple 2 and opening at the rear end of the front temple 2 and opening at the front end of the rear temple 3. At one of the front end parts of the joint piece part 5, screw engagement parts 16, which can be inserted into the insertion part 9 and are grooves, recesses, or through-holes, are arranged in parallel at small intervals in the length direction. The connecting piece 5 which is inserted into the insertion part 9 is connected to the threaded part 19.
can be fixed to the insertion section 9 using a set screw 17 that can be engaged with the screw engagement section 16. Further, the exposed joint piece portion 11 that comes off from the insertion portion 9 is attached to one of the front temple 2 or the rear temple 3.
Even when the length of the rear temple 3 is at its maximum, a cover part 10 that covers at least the outside thereof is formed protrudingly.
The outer surface 26 of the front portion of the cover member 10 or the outer surface 26 of the rear portion of the front temple is in contact with the inner surface 27 of the cover member 10. Further, a positioning scale 2 is provided at a pitch equal to the pitch between the screw engaging portions 16.
3 are arranged side by side on either the connecting piece part 5 or the cover part 10, and the other side is provided with a mark 25 that can match the scale, and when the mark 25 matches the required scale 23, the threaded part 19 is the screw engaging part 1
It is characterized by being able to engage with 6.

(Function) By integrating the front temple 2 and the rear temple 3 through the insertion portion 9, the connecting piece portion 5, and the set screw 17, a half-hook type ear hook portion 4a shown in FIG. 1 is provided. A desired temple according to the purpose, such as a temple or a temple having a cable-type ear hook part 4b shown in FIG. 2, can be constructed by simply replacing the rear temple 3.

At this time, by aligning the mark 25 with a required scale, the amount of insertion of the joining piece 5 into the insertion portion 9 can be adjusted, thereby making it possible to adjust the length of the vine to a desired value. . Then, when the set screw 17 is engaged with the screw engaging portion 16 and screwed in the adjusted state, the front temple 2 and the rear temple 3 are reliably integrated. When integrated in this way, a part of the joint piece 5 may come off from the insertion part 9 depending on the length of the temple, but the exposed joint piece 11 has a maximum length. At least the outer side thereof is covered by the cover part 10 even when the cover part 10 is opened.

When the set screw 17 is screwed, the outer surface 26 of the front portion of the rear temple 3 or the outer surface 26 of the rear portion of the front temple 2 comes into contact with the inner surface 27 of the cover portion 10 (see Fig. 4). , the cover portion resists outward expanding deformation of the front temple 2 or the rear temple 3, and improves stability at the joint portion of the front temple and the rear temple.
