The temple 300 is divided into a front half 301 and a rear half 302, and an insertion hole reaching the window 303 is formed through the front half 301. The latter half 302 is inserted into the insertion hole,
An adjusting knob 305 having an internal thread is screwed to the external thread 304 provided at the tip thereof.

Then, when the adjusting knob 305 is rotated, the latter half body 302 slides in the front-rear direction by the female screw, and the entire length of the temple 300 is adjusted.

(Problems to be Solved by the Invention) However, the above conventional example has the following problems.

(A) Because the components are sealed (the slide hole 10
3 is inside the adjusting knob 205, and is inside the insertion hole of the front half body 301). (A) Perspiration of the user is likely to be accumulated in the sealed portion, which causes corrosion.

(B) Maintenance such as lubrication is difficult.

(C) Since the plating solution is likely to remain in the manufacturing process (causing corrosion), long-time cleaning is required, resulting in high cost.

There is a problem.

In order to prevent the latter half bodies 102 and 302 from rotating, the one shown in (b) must be molded into a sectional shape corresponding to the slide hole 103 and the insertion hole. Therefore, the latter half
The design of 102,302 is limited and affects the decorativeness of the entire temple 100,300.

In the case of (c), in order to prevent rotation of the latter half body 202, it is necessary to cut the cross-sectional shape of the end portions of the front and rear half bodies 201 and 202 into a semicircular shape, which increases the cost.

This invention is to solve the above-mentioned problems, and it is possible to open the constituent parts for length adjustment and freely change the cross-sectional shape of the latter half of the body. The aim is to provide temples for unwanted eyeglasses.

(Means for Solving the Problem) In order to achieve the above object, the present invention comprises a front half and a rear half divided along the front-back direction, and the front half is provided with a plurality of arm portions toward the rear half. And an open space is formed between the arms, and a support member provided with a female screw from the front to the rear is arranged in the open space, and further in the open space and closer to the rear half body than the support member. At this position, an adjusting knob having a male screw to be screwed into the female screw is arranged, the adjusting knob is rotatably connected to the latter half body, and the latter half body is slidable in the front-rear direction along the front half body. It is provided with a guide member to be held on.

(Operation) In this invention based on the above configuration, when the adjusting knob is rotated, the male screw moves in the front-rear direction along the female screw of the support member. The rear half body connected to the adjusting knob slides in the front-rear direction while being guided by the guide member, and the entire length of the temple is adjusted.

Here, the support member, the male screw, and the adjusting knob are exposed in an open space formed between the arms of the front half body.

(Embodiment) Next, this invention will be described with reference to FIGS.

1 to 6 show the first embodiment. A temple 2 of eyeglasses that is openably and closably connected to a rim 1 includes a front temple (front half) 3 and a rear temple (half) 4 that are divided along the front-rear direction. The front temple 3 is provided with two arms 5 parallel to the rear temple 4, and an open space 6 is formed between the two arms 5. A screw receiving portion 7 as a support member fixed to the arm portion 5 is provided in the open space 6, and a female screw 8 is provided at the center of the screw receiving portion 7 from the front to the rear.

Further, at a position closer to the rear temple 4 side than the screw receiving portion 7 in the open space 6, a male screw 9 screwed into the female screw 8 is provided.
There is provided an adjusting knob 10 having. This adjustment knob 10
Is rotatably connected to the connecting rod 11 of the rear temple 4 by the structure shown in FIG. The adjusting knob 10 is provided with an insertion hole 12 and a large-diameter engagement groove 13. An engaging claw 14 provided at the tip of the connecting rod 11 is arranged in the engaging groove 13. The engagement claw 14 has a larger diameter than the insertion hole 12.

On the other hand, a guide member 15 is fixed to the connecting rod 11. As shown in FIG. 3, the guide member 15 is provided with a guide hole 16 so as to be movable with respect to the arm 5. Thus
The rear temple 4 is slidable in the front-rear direction with respect to the front temple 3.

Next, the operation of the temple 2 will be described.

First, when the adjusting knob 10 is rotated in a predetermined direction in the state shown in FIG. 1, the male screw 9 moves forward along the female screw 8, so that the rear temple 4 slides forward as shown in FIG. The overall length will be shorter. Also, adjust knob
When 10 is rotated in the opposite direction to the above, the rear temple 4 slides backward as shown in FIG. 6 by the operation opposite to the above, and the temple 2 as a whole becomes longer.

In this way, by adjusting the length of the temple 2 steplessly, it is possible to perform fitting in accordance with the facial shape of the user.

And since all the members that are the mechanism for adjusting the length of the temple 2 are exposed in the open space 6,
The user's sweat does not collect and corrode, and maintenance such as lubrication is easy. Further, in the manufacturing process of the temple 2 as well, since there is no sealed part in each component, the plating liquid does not remain. Therefore, the cleaning is easy and the manufacturing cost can be reduced.

Further, since the guide member 15 serves as both the slide mechanism and the rotation preventing mechanism of the rear temple 4, the cross-sectional shape of the temple 4 can be freely set, and the temple 2 having excellent decorativeness can be provided. Since the cutting process for preventing rotation is unnecessary, the cost is low.

Furthermore, when the adjusting knob 10 is rotated from the state shown in FIG. 6, the rear temple 4 is separated from the front temple 3. Therefore, if various temples of various shapes and colors are prepared and used by appropriately exchanging them, various variations can be enjoyed according to T / P / O.

7 and 8 show the second embodiment. In this embodiment, guide grooves 17 are provided above and below the guide member 15, and the arm portions 5 are recessed in the guide grooves 17. Other configurations, operations, and effects are similar to those of the first embodiment.

The effect is similar to that of the first embodiment.

(Effect of the Invention) Since the present invention is configured as described above, by adjusting the length of the temple steplessly, it is possible to perform fitting according to the facial shape of the user.

Since all the members that are the mechanism for adjusting the length of the temple are exposed in the open space, sweat of the user does not accumulate and corrode, and maintenance such as lubrication is easy. Further, in the temple manufacturing process as well, since there is no sealed portion in each component, the plating liquid does not remain. Therefore, the cleaning is easy and the manufacturing cost can be reduced.

Further, since the guide member serves as both the slide mechanism and the rotation preventing mechanism of the rear temple, the temple cross-sectional shape can be freely set, and it is possible to provide a temple with excellent decorativeness and There is no need to cut the latter half body to prevent rotation, which results in low cost.
