It is premised that it is configured to include a hinge part 30 that enables the opening and closing movement of the leg part from the spectacle frame as a starting point.

Since the spectacle frame 10 is similar to or identical to a conventional one as shown in the drawing, a detailed description thereof will be omitted.

That is, the spectacle frame 10 is used as a means for fixing the position of the spectacle lens by inserting the spectacle lens in the same or similar manner as the prior art, but in the present invention, a predetermined fitting hole 11, stopper 12, processing The hinge part 30 is fixedly coupled by the interaction of the hole 13 or the like.

In detail, the spectacle frame 10 is further configured with a fitting hole 11 for inducing internal acceptance of the connector 35 and a stopper 12 for preventing external detachment of the connector from the inside of the fitting hole. do.

In addition, in the eyeglass frame 10, a processing hole 13 must be drilled through to form a space in which the connector 35 can be fixed to the end of the stopper 12 protruding from the inner surface of the fitting hole 11, and the connector 35 can be fixed. , At this time, it is obvious that the shape or structure of the processing hole 13 is not limited to that shown in the drawings.

The stopper 12 may be selectively provided on any one of the inner surfaces of the fitting hole 11 as shown in FIGS. 6 and 7, and a setting space should be secured around the stopper so that the end of the connector 35 can be inserted into the inside and fixed. do.

In particular, such a stopper 12 should be built with a predetermined inclined surface for more robust coupling force and elastic fixing, and eventually, after the end of the connector approaches the fitting hole, shape deformation is performed along the inclined surface of the stopper, and the stepped space Can be position constrained.

Here, the stopper 12 is closely related to the shape of the connector 35 to be described later, and due to the shape characteristics of the connector, it is engaged with the stopper made of an inclined surface or other structure to restrain the connector.

On the other hand, the hinge part 30 proposed in the present invention includes a connector 35 bent in a setting shape, and the connector 35 is an attachment type in which positioning is restricted by simple fitting at both ends of the spectacle frame. do.

At this time, the connector 35 is provided in a vertically branched shape and is positionally restricted by the binding member 1 above and below the fastening piece 21 located at the end of the temple 20.

The above-described detailed configuration of the connector 35 is eventually related to the interaction of the stopper 12, and organic mutual coupling with the stopper can be achieved by the branched connector structure corresponding to the set width.

For example, the gap between the third extension surface 35-3 and the fifth extension surface 35-5 corresponds to the width of the stopper 12, and the length of the fourth extension surface 35-4 and the stopper The widths match each other within the margin of error. In addition, the fourth extension surface adheres to the position at the end of the stopper, which is due to the step caused by the formation of the stopper 12 on the inner surface of the fitting hole 11.

In addition, the end of the connector 35 that is internally constrained to the spectacle frame 10 may be configured in a concave-convex shape.

This is shown in detail in FIG. 8, and as shown in the drawing, the end of the connector 35 accommodated inside the fitting hole 11 is made of a concave-convex surface within a set range, thereby increasing the contact area of the connector in the inner space of the fitting hole. As it is secured, it contributes to the increase in bonding strength.

When the user wears the glasses of the present invention, it is necessary not to feel uncomfortable due to lateral pressure transmitted from the temples 20 to the left and right sides of the face.

As the elastic restoring force of the elastic member 40 increases, the lateral pressure transmitted from the temples 20 to the left and right of the user's face increases, and the elastic restoring force of the elastic member 40 is determined by the material and thickness.

As the material of the elastic member 40, a material having elastic restoring force such as rubber, foamed resin, or urethane may be used, and the elastic restoring force increases proportionally as the thickness of the elastic member 40 increases.

Depending on the direction of contact between the first end 22 and the second end 41, the contact point X through which force is transmitted varies.

Therefore, the first end 22 and the second end 41 have an arc shape when viewed from the plane direction, so that the force is transmitted along the contact direction between the first end 22 and the second end 41 can allow the position change of the contact point X to move flexibly according to the shape of the arc.

With the above configuration, in this embodiment, the maximum value of the angle R at which the temples 20 can be opened from the glasses frame 10 is larger than in the prior art, so that users with large heads can wear glasses smoothly. do,

The elastic member 40 prevents the temples 20 from being separated from the user's head due to excessive opening of the temples 20 when the user wears the glasses, but prevents the lateral pressure transmitted from the temples 20 to the left and right sides of the face. By selecting the material and size of the elastic member 40 so as not to feel discomfort due to it, it is possible to provide glasses having a comfortable fit compared to the prior art.
