Abstract

<P>PROBLEM TO BE SOLVED: To provide a structure which can be more exactly adapted to facial forms, can be adapted to a plurality of the facial forms by a combination of the same frame and the same temples, can be set to the gripping force in such a manner that the gripping force of the spectacles are made to meet the requirement of a user; can be the more appropriate spectacles by making the effective adjustment of the angles of the frame in the case of bifocal and thick lenses, and can be adapted to the degradation in the elastic force of the spectacles themselves due to changes with the lapse of time, and can be adapted to the facial width of a person that change. <P>SOLUTION: The spectacles are of the structure formed by integrating the frame 1 and the temples 5 by means of balls 2, A sockets 3, B sockets 4, adjusting screws 6, and set screws 7 to a spherical hinge. The resistance to turning of the spherical hinge is adjusted by the tightening force of the adjusting screws 6. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

Industrial application fields

  The present invention relates to a structure of eyeglasses.

General eyeglasses are made with an effort to match each person's face shape, but it is almost impossible to make eyeglasses with perfectly adapted dimensions. The major factor is that the left and right ears are not arranged symmetrically with the nose at the center. Also, maintenance is indispensable because the elasticity of the glasses itself decreases with age and the human face also changes.

Problems to be solved by the invention

The structure of the glasses can be adapted as much as possible to the human face shape.

Means for solving the problem

The crane is connected with a spherical hinge so that the crane can be adjusted vertically and horizontally with respect to the frame.

Action

It is possible to form eyeglasses that are more suitable for the face shape and lens of the person than before.

Since the relative position between the vine and the frame can be changed, the same product can be adjusted to suit a plurality of people.

In FIG. 1, 1 is a frame, 2 is a sphere, 3 is a socket A, 4 is a socket B, 5 is a temple, 6 is an adjusting screw, 7 is a set screw, and 8 is a lens. The sphere 2 has a rod portion 2a and is integrated with the frame 1 by bonding or the like. The A socket 3 is a half crack and has a notch 3a and screw holes 3b and 3c. The B socket 4 is half cracked and has holes 4a and 4b. The temple 5 has a hole for allowing the adjusting screw 6 and the set screw 7 to pass therethrough.

The half-cracked A socket 3 and B socket 4 are integrated with the temple 5 by the adjusting screw 6 and the set screw 7, and the ball 2 is built in to form a spherical hinge. Then, the rotational resistance of the spherical hinge is adjusted by adjusting the tightening force of the adjusting screw 6. Smooth rotation resistance can be obtained by appropriately selecting the elastic coefficient of the material of the temple 5 to be compressed. When the temple 5 is folded and stored, the notch 3 a of the A socket 3 stores the rod portion 2 a of the sphere 2.

Other examples

In FIG. 3, 10 is a frame, 11 is a sphere, 12 is a socket, 13 is a temple, and 14 is a lens. The sphere 11 has a rod portion 11a and is integrated with the frame 10 by bonding or the like. The socket 12 has a finger 12a having elasticity. The socket 12 grips the ball 11, and a smooth rotation resistance is obtained by an appropriate elasticity of the finger 12a. The socket 12 and the temple 13 are integrated by bonding or the like.

The invention's effect

Since the present invention is configured as described above, the following effects can be obtained.

Even if the positions of the left and right ears are not perfectly symmetrical with the nose supporting the glasses, the vine position can be adjusted up, down, left, and right to fit the user with a spherical hinge. For example, the height of each vine of the left eye and the right eye and the interval between the left and right can be changed.

If the center distance of the eyeball is the same, it can be adapted to a plurality of users, so even a combination of the same frame and vine can be adapted to a plurality of face shapes. As a result, costs are reduced.

In the case of a bifocal lens, more appropriate glasses can be obtained by adjusting the angle of the frame. It is effective especially when the degree is strong.

FIG.

In this embodiment, since the gripping force of the glasses can be adjusted, it is possible to set the gripping force according to the user's request. In addition, since the width of the face can be reduced or the elasticity can be corrected to compensate for the aging of the vine, the use period of the glasses can be extended.
