The present invention relates to an eyeglass that can be opened outward so that it can be easily worn.

[0002]

2. Description of the Related Art Conventionally, as a spectacle frame capable of opening a temple of this kind outward from a predetermined position, a rim 2 for holding a lens 1 is fitted with a metal fitting 3 as shown in FIGS. It is proposed that one end of the tip 4 is fixed and a temple 5 is connected to the other end of the tip 4 via a spring hinge 6.

Specifically, the spring hinge portion is fixed to the temple 5 by brazing the case 5a, while a sliding set including a temple side hinge 6a, a spring 7a and a spring receiving piece 7b is placed inside the case 5a. Insert it slidably and insert pin 8 into the long hole of hinge 6b on the temple side from one side wall of case 5a.
And the case 5a and the temple 5 are slid with respect to the temple-side hinge 6a while being opened further outward from a predetermined position.

In the above conventional example, the case 5a of the temple 5 is used.
Inside of the, spring 7a, spring receiving piece 7b, temple side hinge 6
Since the sliding set containing a is installed, the above case 5a
Has a drawback that the shape becomes very long and thick, and the shape becomes large as a whole, which impairs aesthetics and makes the glasses heavy. Furthermore, since the connection length between the case 5a and the temple 5 becomes large, the working time for brazing and the like increases.

In response to the above problem, as shown in FIG. 7, a notch 4a 'is provided at the end of the wisdom 4'on the temple 5'side, and a convex through hole 6b'-is formed on the wiping side hinge 6b'. 1 and a convex pressing portion 7b 'that slides inside the through hole 6b'-1.
There is provided a spectacle frame in which the spring 7a 'is pressed and the end of the spring 7a' is locked by a screw 9 '. (Actual Kaihei 3-47516)

Further, as shown in FIGS. 8A and 8B, the dovetail grooves 5b "and 6a" -1 are provided on the temple 5 "and the temple side hinge 6a" so as to face each other, and these dovetail grooves 5b "and 6a are provided. "-1" is connected through the letter-shaped front and rear piece members 10a ", 10b", the compression spring 7a "is interposed between these piece members 10a", 10b ", and the front side piece member 10a" is a temple. There is provided a spectacle frame which is fixed by tightening a nut 9 "from the outside of the 5". (JP-A 61-176908)

[0007]

However, in the conventional example shown in FIG. 7, although the length of the spring hinge portion is shortened and the structure is simplified, the temple does not come into contact with the wisdom in a stationary state. Since it is assembled only by the engagement of the wisdom side hinge and the temple side hinge, the strength of the connection part between the wisdom side and the temple is weak and there is a problem of instability.

Further, in the conventional example of FIG. 8, the number of parts is large and the structure is complicated, so that the assembling work is troublesome and
The glasses themselves become heavy. In addition, since the temple and the temple-side hinge are connected to each other only at the two ends of the dovetail groove by two separate member members, the temple and the temple-side hinge have a weak connection strength.

The present invention has been made in view of the above problems, and improves the structure of the spring hinge that connects the temple and the wisdom of the spectacle frame to improve the connection strength between the temple and the temple side hinge. The number of parts is reduced, and
The purpose is to provide beautiful spectacles.

[0010]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention connects a temple of a pair of spectacles and a wisdom by a spring hinge so that the temple can be freely rotated from a closed position to a predetermined open position. Is a frame of eyeglasses that can be opened further outward from the open position of the temple, and a long groove that slidably accommodates a stopper and a spring for urging the stopper is provided on the hinge attachment side of the temple. A spring receiving portion is provided at one end of the long groove, and guide holding walls for temple side hinges are provided on both sides of the long groove, while a side wall and a spring receiving portion which slidably engage with the guide holding wall are provided at the temple side hinge.

When opening the outside from a predetermined position, the temple to compress the spring is to provide a spectacle frame, characterized in that it is configured to slide.

In the spectacle frame, the spring receiving portion of the temple has a predetermined gap between the temple and the tip of the temple. Further, in the above spectacle frame, the length of the guide holding wall of the temple is shorter than that of the side wall of the temple side hinge, and the difference is the same as the gap.

[0012]

In the spectacle frame of the present invention, when wearing spectacles,
Since the temple can be slid with respect to the hinge on the temple side while compressing the spring, the temple can be further extended outward from the predetermined open position.

Further, in the spectacle frame, since the temple and the temple-side hinge are provided with the guide holding wall and the side wall which slidably engage with each other, the strength of the connecting portion between the temple and the temple-side hinge is increased. It is possible to reduce the number of parts.

When it is mounted in the screw hole 17f of No. 7, the insertion projection 19c is set to project inward from the spring receiving portion 17e of the temple-side hinge 17.

The relationship between the length L2 of the side wall 17d of the temple-side hinge 17 shown in FIG. 2 and the length L3 of the guide holding wall 15b of the temple 15 shown in FIG. 1 is as shown in FIG. 3 (A). , L2> L3, and L2-L3 = S.

Next, a process of assembling the temple 15 and the temple-side hinge 17 having the above-mentioned structure will be described. First, the stopper 20 is arranged at the end of the stopper slide portion 15d of the long groove 15a.

Next, the spring 21 is attached to the long groove 15a.
It is inserted into the inside, one end thereof is brought into contact with the spring receiving portion 15c, the spring 21 is compressed, and the other end thereof is brought into contact with the stopper 20 to be assembled.

Thereafter, the temple 15 having the stopper 20 and the spring 21 assembled therein is attached to the temple-side hinge 17 from the stopper slide portion 15d side. Specifically, the end surface of the guide holding wall 15b on the stopper slide portion 15d side of the temple 15 is arranged in the opening of the temple side hinge 17, and the guide holding wall 15b is engaged with the side wall 17d to move the temple 15 to the temple side hinge 17. The spring receiving portion 17e is pushed in and inserted.

The temple 15 is pushed until the stopper 20 arranged on the stopper slide portion 15d comes to a position corresponding to the screw hole 17f of the temple side hinge 17.

In this state, the screw hole 1 of the temple side hinge 17
The screw 19 is inserted into 7f, and the insertion protrusion 19c of the screw 19 is inserted into the through hole 20a of the stopper 20. Since the stopper 20 is movably accommodated in the long groove 15a, the temple 15 connected to the stopper 20 via the screw 19 is slidably attached to the temple-side hinge 17.

In the assembled state, the long groove 15a of the temple 15 is arranged with the long groove 17c of the temple hinge 17 on the upper side, as shown in FIG.
The storage part 22 which stores is formed. In the storage section 22,
As shown in FIG. 3C, one end of the spring 21 abuts on the spring receiving portion 15c of the temple 15, and
The other end is in contact with the spring receiving portion 17e of the temple-side hinge 17 to compress and store the spring 21. As a result, the spring 21 exerts a force of returning to the original length, and presses the spring receiving portion 15c of the temple 15 and the spring receiving portion 17e of the temple-side hinge 17 in opposite directions, and thus the temple-side hinge 17 The stopper 20 connected to the stationary portion is stationary while being pressed against the end of the stopper slide portion 15d of the temple 15.

In the stationary state, the guide holding wall 15b of the temple 15 and the side wall 17d of the temple-side hinge 17 have the length relationship (L2-L3 = S), as shown in FIG. There is a gap S between the end of the guide holding wall 15b on the side of the stopper slide 15d and the spring receiving portion 17e of the temple hinge 17.

In this way, after the temple side hinge 17 and the temple 15 are assembled, the tip side hinge 2 is connected to the tip 24 by brazing or gluing welding in advance.
The hinge eye 23a of No. 3 is engaged with the hinge eye 17b of the temple side hinge 17, and the hinge screw 25 rotatably pivots from the outside to complete the assembly.

When wearing the glasses assembled as described above,
The temple 15 is rotated to a predetermined open position with the hinge screw 25 as a rotation axis. Further, as shown in FIG. 3 (C), when a force X is applied to open the temple 15 in the outward direction in order to make it easier to put on the glasses, the temple 15 moves relative to the temple-side hinge 17 and FIG. It will be in the open state shown in.

More specifically, the temple-side hinge 17 rotates about the hinge screw 25 as a fulcrum, and in response to this rotation, the front end face of the temple 15 which is in contact with the rear end face of the tip 24 is pushed,
The temple 15 compresses the spring 21 and slides with respect to the temple-side hinge 17. As shown in FIG. 4A, the sliding of the temple 15 ends when the end of the guide holding wall 15b of the temple 15 on the stopper slide portion 15d abuts on the spring receiving portion 17e of the temple hinge 17.

In the opened state, the guide holding wall 15b of the temple 15 moves in the direction of the spring receiving portion 17e by the gap S, so that the spring 21 is compressed by the length S as shown in FIG. 4 (B). . When the application of the force X for opening the temple 15 outward is stopped by the spring force generated by the compression of the slide 21, the temple 15 returns to the predetermined open position shown in FIG.

[0031]

As is apparent from the above description, in the spectacle frame of the present invention, the temple and the hinge on the temple side are integrally formed with the guide holding wall and the side wall which slidably engage with each other, and engage with each other. Since the temples and the hinges on the temple side are connected by doing so, the strength of the connecting portion between the temples and the hinges on the temple side can be reliably maintained. Further, since the temple and the temple side hinge are not connected as separate members, the number of parts can be reduced.

At the predetermined open position of the temple, the end face of the temple abuts against the end face of the tooth and is supported, and since the temple side hinge and the tooth side hinge are connected via the hinge screw, It has various advantages such as being able to solve the problem of strength of the connection portion with the wisdom.
