Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention is to maintain the folded state of the eyeglasses, more specifically, the temples on both sides, and when one temple is opened, the other temple is automatically opened, and both temples can be opened with one touch. Regarding eyeglasses that can be worn.

[0002]

[Prior art]

 In conventional general eyeglasses, temples are attached to the ends of the armatures provided at both ends of the lens frame with hinges, and both temples are folded by the action of the spring incorporated in the hinge and the cam provided on the hinge. It is designed to be held in either the posture or the open posture.

[0003]

[Problems to be solved by the device]

 By the way, in the conventional eyeglasses as described above, both temples maintain the folded and open postures individually, so when trying to wear the temples in the folded state, the temples must be opened individually. It is difficult to operate with one hand, and it is extremely dangerous to wear glasses with one hand while driving a car, for example.

[0004] Furthermore, eyeglasses in which the temples on both sides are always open have been proposed by Japanese Utility Model Laid-Open No. 5-30828, but since the temples on both sides are about to always be in the open posture, the temples are folded. This is inconvenient because it must be stored in the spectacle case when it is held, and it has to be taken in and out of the spectacle case.

Therefore, an object of the present invention is to make one temple always open, while the other temple self-holds either a folded posture or a folded posture, and the folding of one temple is pressed down by the other temple. The purpose is to provide eyeglasses that can be worn by one-touch operation by holding them while holding the temple open.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention relates to eyeglasses in which temples are attached to the ends of the arms provided at both ends of the lens frame with hinges, respectively, while the temples maintain an always open posture with elastic members. On the other hand, a structure is adopted in which the temple is elastically biased and the temple is held by a resilient member in either a folded posture or an open posture.

[0007]

[Action]

 After folding one temple, fold the other temple, the folding of one temple can be held by holding it with the other temple, and if you hold the other temple in your hand when you wear it, Is automatically opened and can be worn with one touch.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1A and 1B, temples 4 and 5 are attached with hinges 6 and 7 to the end portions of the end pieces 2 and 3 provided at both ends of the lens frame 1, and the left side of FIG. One of the temples 4 located at is elastically urged to automatically return to the open position shown by the solid line in FIG. 1 (B), and the other temple 5 has the folded posture shown in FIG. It is designed to elastically hold itself in one of the open positions shown by the solid line in B).

2 (A) and 2 (B) show the structure of a hinge 6 for attaching the temple 4 to the end of the armature 2, and a hinge piece 8 fixed to the end of the armature 2 and the hinge piece 8. The other hinge piece 10 attached to the shaft 9 by means of the pivot 9, the storage portion 11 fixed to the inner surface side at the tip of the temple 4 and holding the other hinge piece 10 movably in the length direction of the temple 4. It comprises a coil spring 12 which is assembled in the storage part 11 and presses the other hinge piece 10 into the storage part 11, and one hinge piece 8 is provided with a cam edge 13 against which the end of the storage part 11 is pressed. ing.

The cam edge 13 is formed at the rear end of the one hinge piece 8 in a substantially semi-circular shape projecting inward from the rear, and the cam edge 13 has a forked top and bottom shape, and the other hinge piece 10 in between. The circular tip portion of the first hinge piece 8 is fitted in, and the one hinge piece 8 and the other hinge piece 10 are connected to each other by a pivot 9 eccentric to the cam edge 13 toward the outside.

On the other hand, in the hinge piece 10, the rear end side of the circular tip portion and the shaft 14 connected to the rear end are housed in the housing portion 11, and the coil spring 12 fitted on the shaft 14 is fitted to the front end side of the shaft 14. It is loosely fitted and is contracted between a spring bearing 16 fixed to the housing portion 11 by a pin 15 and a spring bearing 17 fixed to the rear end of the shaft 14, and the other hinge piece 10 receives the other hinge piece 10 via the shaft 14. The pressure is within 11.

Due to such a pulling force of the coil spring 12, the front end surface of the housing portion 11 is in pressure contact with the cam edge 13 of the one hinge piece 8.

On the other hand, the temple 4 is rotatable around the pivot 9 with respect to the armor 2, and the pivot 9 is eccentric to the cam edge 13 toward the outside, so that the tip of the housing portion 11 is attached to the cam edge 13. When the surfaces are in pressure contact, on the other hand, the temple 4 always generates a rotational force in the outward direction in which the radius of the cam edge 13 becomes smaller with the pivot 9 as the center. When one temple 4 is folded and freed as shown in (A), it automatically rotates clockwise in the same figure, and as shown in FIG. 2 (B), one temple 4 is moved from the rear end of the armature 2. It has an open posture that projects backwards.

The open posture of the first temple 4 is maintained by the front end surface of the first temple 4 contacting the rear end surface of the armature 2.

3 (A) and 3 (B) show the structure of the hinge 7 for attaching the temple 5 to the end of the armature 3 on the other hand, and since it is basically the same as the hinge 6 described above, The same parts are designated by the same reference numerals, and only the differences will be described.

The cam edge 13 provided on the one hinge piece 8 of the hinge 7 has a holding portion 13a in an open posture which is at a right angle to the rear end of the end piece 3, and an acute angle from the inner end of the holding portion 13a. It is formed by a folding posture holding portion 13b extending forward, and one of the folded state of the other temple 5 and the open posture shown in FIG. It is designed to elastically self-hold.

It should be noted that any one of the hinges 6 and 7 has a structure in which the temples 4 and 5 can be pushed outward while the temples 4 and 5 are in the open posture. The hinges 6 and 7 may have a structure other than that shown.

The spectacles of the present invention have the above-described structure. When the temples 4 and 5 are held in the folded state, the temple 4 is first folded and then the temple 4 is folded as shown in FIG. 1 (A). Then, the other temple 5 is folded, and the other temple 5 is superposed on the one temple 4.

On the other hand, the temple 4 has elasticity to return to the normally open posture, but the other temple 5 elastically holds either the folded posture or the open posture, and therefore, the other temple 5 is folded. By overlapping the one temple 4 on the one temple 4, the folded state of the one temple 4 can be pressed and held by the other temple 5, and both temples 4 and 5 are folded as shown in FIG. 1 (A).

When wearing glasses, the other temple 5 located on the outer side is held by a fingertip, and when the lens frame 1 is lifted as a whole, the weight of the lens frame 1 side causes the other temple 5 to move. Automatically takes on the open posture, and the temple 4 on the other hand is released from the pressing and holding by the other temple 5, so that the temple 4 automatically rotates to the position of the open posture.

As described above, the one-touch operation of holding the temple 5 on the other hand with the fingertip and lifting it up brings both temples 4 and 5 into the open posture as shown by the solid line in FIG. You will be able to install it as it is.

As described above, by stacking the other temple 5 on the one temple 4, the folded state of both temples 4 and 5 can be maintained without using a spectacle case, and the other temple 5 can be held with a fingertip when worn. With one-touch operation of holding and lifting the whole body, both the temples 4 and 5 are in the open posture and can be worn as they are with one hand, and the glasses can be worn safely, for example, while driving a car.

[0024]

[Effect of device]

 As described above, according to this invention, the folded state of both temples can be held by overlapping the two temples, while on the other hand, the temples can be opened by simply holding the temples with your fingertips and lifting the entire temple, and with one hand. Since it can be worn with one-touch operation, it can be worn safely while driving a car.

Further, since both temples can be kept in the folded state without being inserted into the spectacle case, they can be worn quickly and are convenient.
