Abstract

PROBLEM TO BE SOLVED: To stably obtain jerking to impart adequate resistance to turning action and to impart a spring characteristic to the turning action so as to improve the mountability of spectacles by holding resin ornaments in housing parts of temples and bringing the resin ornaments into pressurized contact with the outer peripheral surfaces of the bearing parts of wraparound endpieces. SOLUTION: An opening formed by branches 3b and 3c is the housing part 6 in which the resin ornament 5 as an energizing member is housed. The resin ornament 5 is formed to an elliptic shape which is nearly the same as the shape of the housing part 6 and is formed with the recessed groove 5a to be fitted with the branches 3b and 3c on its outer periphery. While the resin ornament is exchangeable as desired, the resin ornament retains the state that the resin ornament is fitted into the housing part 6. The end 5b of the resin ornament 5 is held in pressurized contact with the bearing part 2a in the state that the resin ornament 5 is fitted into the housing part 6 and, therefore, the impartation of the jerking by the sliding resistance to the opening and closing (turning) action of the temple 3 is made possible. Also, the opening action of the temple 3 in an abutment position may be stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge structure for spectacles, and is a structure capable of generating "blow" and "spring" when opening and closing a temple.

[0002]

2. Description of the Related Art A general hinge structure of eyeglasses in the prior art is, as shown in FIG. 10, a frame 1 joined to a yoke 110 and a temple 111 by a method such as brazing.
01 and 102 and a screw 103 for fastening the two frames 101 and 102.

In recent years, rimless eyeglasses have been widely used. However, as shown in FIG.
A structure in which the 20a and 121a are integrally formed is also frequently used.

[0004] In such a hinge structure, a "gap" at the time of opening / closing the temple (hereinafter, a turning torque required for opening / closing the temple is referred to as "gaki") is used to slide a metal piece by tightening a screw. It is obtained by the sliding resistance generated on the moving surface. In addition, there is a type in which a resin washer is interposed between sliding surfaces to stabilize sliding resistance and impart lubricity.

[0005]

However, in the case of the above-mentioned prior art, the sliding resistance by the sliding surface perpendicular to the pivot axis of the hinge is mainly used to obtain the head. If the screws are loosened due to the opening and closing operations of the temple, the urging force in the direction of pressing the sliding surfaces in the axial direction is weakened, which immediately leads to a decrease in the surface pressure of the sliding surfaces, and there is a possibility that the lifting is reduced or eliminated.

Referring to FIG. 10 as an example, when the screw 103 is fastened and fixed to the top 101 of the yoke 110 side, the shaft hole 102b of the bearing portion 102a of the top 102
Is slidably rotated on the outer peripheral surface of the screw 103 at the axial center, and thus eccentricity is likely to occur due to the fitting of the axial hole 102b with the outer peripheral surface of the screw 103 at the axial center (generally common). If the fitting is tight, the eccentricity is reduced, but the screw is rotated, so that the fitting is performed with a certain clearance.) This may hinder the smooth rotation of the temple.

Further, in order to improve the wearing and detaching properties of the glasses and the fit of the temple at the time of wearing, a spring hinge using a spring spring or the like is employed. An urging force for holding the camera in a position where rotation is restricted (for example, in a state where the temples are opened and glasses can be mounted), or the rotation restriction position is allowed by allowing a little more opening from the rotation restriction position. There is a lot of eyeglasses that have a biasing force to return, and the temples have more freedom in the rotation angle of the temple by opening further after the rotation is restricted, but the spring hinge has a structure. However, there is also a problem that parts processing and assembling are difficult due to the conventional attempt to make the structure as small as possible, which leads to an increase in cost.

An object of the present invention is to solve the above-mentioned problems of the prior art. It is an object of the present invention to provide an eyeglass for rotatably connecting two members constituting eyeglasses such as a temple and a temple. In the hinge structure, a hinge structure capable of stably obtaining a lift that gives a moderate resistance to the turning operation, and improving the wearability of the glasses by giving a spring property to the turning operation, is provided. To provide.

It is also preferable that each of the bearing portion and the urging member is provided with an engagement portion for restricting the rotation angle of the two members constituting the spectacles in contact with each other.

The rotation angle of the two members constituting the spectacles is regulated by the engaging portion. For example, when the two members constituting the spectacles are a skull and a temple, the opening / closing angle of the temple can be set. Further, the biasing member is formed of a resin material or a rubber-like elastic body, and it is possible to obtain a spring property that allows some rotation after the rotation angle is regulated by using the elasticity.

Further, two members constituting the eyeglasses rotatably connected by the connecting means, a sliding member sliding along a guide portion provided on one of the two members, It is characterized by comprising a connecting member for connecting the sliding member to a predetermined position of the other member of the two members that is separated from the rotation axis of the connecting means.

[0016] With this configuration, the sliding member slides along with the connecting member along the guide portion provided on one of the members along with the rotating operation of the two members constituting the eyeglasses,
The sliding resistance makes it possible to give a swing to the turning operation.

The connecting member is preferably a link, so that the sliding member can be reliably moved with the turning operation of the two members.

Preferably, one of the two members includes a rod portion used as the guide portion, and the sliding member includes a fitting hole that slides on the rod portion. The configuration of the unit can be simplified.

It is also preferable that the guide portion and the sliding member are magnetically attracted to each other by magnetic force generating means provided on at least one of them, so that the sliding resistance according to the magnitude of the magnetic attraction force is stabilized. Can be obtained.

The sliding member and the connecting member are formed by opening a part of a central portion in the axial direction of the elastic cylindrical member, and forming the rod-shaped guide portion and the other of the two members. It is also preferable to have two fitting cylinder parts and a flexible part connecting the two tubular parts.

By providing such a cylindrical member, at least one of the rod-shaped guide portion and the two cylindrical portions fitted with the other of the two members is provided.

The angle of rotation of the two engaging members is restricted. For example, when the two members constituting the eyeglasses are a yoro and a temple, the opening / closing angle of the temple can be set. . Further, the rotation angle is not limited by the direct contact of the two members constituting the glasses,
By setting the shape and material of the connecting member, it becomes possible to obtain a spring property that allows some rotation by its bending.

It is preferable that the urging member or the sliding member is made of a resin material.

It is also preferable that the two members constituting the spectacles are a yoroi and a temple.
