Description

The present invention relates to the structure of spectacles.

General spectacles are made in an effort to fit each person's face shape, but it is nearly impossible to manufacture spectacles with dimensions that are perfectly adapted. The main reason for this is that the left and right ears are not completely symmetrical with the nose at the center. In addition, the elasticity of the spectacles itself decreases with aging, and the face of a person changes, so maintenance is essential.
Japanese Patent No. 4609795 addresses this problem.

Patent No. 4609795

[Development of wearing comfort in spectacle frames] Journal of the Japan Society of Mechanical Engineers 2009.12 p36-37

To improve ease of use while taking advantage of the features of spherical hinge spectacles (Patent No. 4609795). To prevent the detachment of a temple due to the falling off of screws of general spectacles.

The temples of ordinary spectacles are connected to the hinge portion of the frame with screws, but the temples are connected to this hinge portion via a spherical hinge structure, replacing the screws with pins.

The spherical hinge spectacles of Patent No. 4609795 have various advantages such as adjustment of temporal pressure and absorption of height difference between the left and right ears. Easy and practical effect can be obtained. However, a large frictional torque is required to prevent slippage during strenuous exercise, and the temple cannot be folded smoothly. The present invention facilitates temple folding.

When ordinary spectacles are used for many years, the screws are loosened due to the rotation of the temples, and eventually the screws come off and the temples often come off. According to the present invention, since the temple has a structure in which the pin is fitted, the temple can be prevented from coming off. In addition, the degree of freedom in selecting dimensions, structural materials, etc. is increased, and the rotation of the temples is made smoother, extending the life of both.

As a result of experiments confirming that there is no hindrance to daily life with only one temple, the other temple can be abolished and replaced. It is possible to adopt a structure in which a decorative banner is screwed to the frame. ,

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 is a frame, 2 is an A socket, 3 is a B socket, 4 is a pin, 5 is an adjusting screw, and 6 is a right temple. The frame 1 has rods 1a and spheres 1b. The A socket 2 is split in half and has a hole 2a into which the adjusting screw 5 is inserted and a hole 2b into which the small diameter portion 4a of the pin 4 is inserted. The B socket 3 is split in half and has a screw hole 3a into which the adjusting screw 5 is screwed and a hole 3b into which the small diameter portion 4b of the pin 4 is inserted. The pin 4 has a small diameter portion 4a and a small diameter portion 4b. The right temple 6 is inserted into the hole 2b, and the small diameter portion 4b is inserted into the hole 3b. The A socket 2 and the B socket 3 are integrated by an adjusting screw 5 and incorporate a ball 1b to form a spherical hinge. The tightening force of the adjustment screw 5 regulates the friction torque of the spherical hinge, and at the same time the pin 4 is pressed and fixed by the A socket 2 and the B socket 3 . A socket portion is formed by the A socket 2 , the B socket 3 , the pin 4 and the adjusting screw 22 .

In FIG. 2, 7 is a left temple and 8 is a lens. There are rods 1c and spheres 1d of frame 1 and there are nose pads 1e and 1f. The left temple 7 is connected to the ball 1d via a socket portion, like the right temple 6 in FIG.

In FIG. 3, 10 is a frame, 11 is a temple, 12 is a banner, 13 is a screw, and 14 is a lens. The frame 10 has rods 10a and balls 10b. The temple 11 is connected to the ball 10b through a socket portion, like the right temple 6 in FIG. The banner 12 is for decoration and displays decorations, names, etc., and is connected to the frame 10 by screws 13. - 特許庁

In FIG. 4, 20 is a C socket, 21 is a D socket, 22 is an adjusting screw, 23 is a temple, and 24 is a ball. The C socket 20 has a pin 20a, the D socket 21 has a pin 21a, and a temple 23 is inserted. form a hinge. The tightening force of the adjusting screw 22 regulates the friction torque of the spherical hinge, and at the same time, the pin 20a and the pin 21a come into contact with the temple 23 and are fitted.
