Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure, and more particularly to a connecting structure effective for connecting a temple and an eyepiece of an eyeglass frame so as to be relatively rotatable.

[0002]

2. Description of the Related Art There are various types of connecting structures for rotatably connecting a temple and an eyepiece of an eyeglass frame to each other, and for example, a connecting structure using a hinge is provided on the market. ing.

[0003] In this conventional connection structure, the fixed side member of the hinge is attached to the yoke side, the movable side member is attached to the temple side, and the fixed side member and the movable side member are connected to each other via a screw. Is relatively rotatable, and the temple can be closed and opened on the back side of the lens.

[0004] However, since the eyeglass frame employing the connection structure having the above-described structure does not have a mechanism for urging the temple in the closing direction, when used in sports or the like in which the temple is intense, There is a possibility that the eyeglass frame is shifted from the mounting position or falls off.

[0005] In order to solve the above-mentioned problems such as displacement of the mounting position, a connection structure using a hinge with a spring has been proposed. For example, a hinge with a spring for spectacles described in Japanese Patent Publication No. 6-64264, a registered utility model publication no.
No. 4670, for example.

[0006] These connecting structures include a mechanism for rotatably connecting the temple and the yoke to the temple of the glasses frame and a mechanism for urging the temple with respect to the yolo by a spring in a rotating direction. Therefore, since the temple can be urged in the closing direction, there is no possibility that the eyeglass frame will be displaced from the mounting position or fall off even when used in sports or the like in which movement is severe.

However, in the connection structure having the above-described structure, since the number of components is large and the structure is complicated, it takes time and effort to process and assemble, and the production cost increases.

In order to reduce such disadvantages, a connecting member which can be moved to a connecting portion of the temple and a moving member for connecting the temple and the yoke relatively rotatably. An urging member capable of urging against the yellowing is provided, and when the temple and the yellowing are relatively rotated, the moving member abuts on the connecting portion of the yellowing and opposes the urging force of the urging member. Some are configured to be pressed. In this connection structure, a pair of pieces are formed as a temple connection portion by bifurcating to form a horizontal gap, and the moving member disposed in the gap is biased by the biasing force of the biasing member. The movable member is positioned on a pair of outer plates arranged to close both sides of the gap of the temple from the outside, and a front portion of the gap. And an inner plate integrally connected between the outer plates and movable integrally with the outer plate, and a biasing member is housed in a deep portion of the gap.

However, in this connection structure,
Since the urging member disposed in the temple gap cannot stay at the predetermined position by itself, the urging member disposed in the temple gap is stopped at the predetermined position. In order to hold the moving member, the moving member must be relied on. That is, in order to hold the urging member at a predetermined position in the gap between the temples, the moving member must be configured to connect the pair of outer plates by the inner plate as described above.

Therefore, when the moving member is moved by being urged by the urging force of the urging member, the contact surface between the moving member and the temple is large and the friction is excessive, so that the moving member can move smoothly. Therefore, there is a possibility that the urging force of the urging member cannot be sufficiently exerted.

The present invention focuses on the above problems and solves the problem. The purpose of the present invention is to prevent the eyeglass frame from being displaced from the mounting position even when used in sports or the like in which movement is severe. There is no danger of falling off, the number of components is small, the structure is simple, the manufacturing unit price can be reduced, and the urging force of the urging member can be fully exerted. It is an object of the present invention to provide a connection structure that is effective for connecting a temple and a yoke relatively rotatably.
