The present invention is characterized by providing a regulating means for moving the lens mounting frame to a hanging position or to an inward position from the hanging position.

[Function] Therefore, when the support piece is pushed into the upper frame when not in use, the lens mounting frame is moved from the hanging position to the inward position by the regulating means, and in this state, the temple is moved against the support piece. When rotated, the temple, support piece, and upper frame surround the lens mounting frame.
It can be folded into a flat and thin shape, and when the support piece is pulled out from the upper side piece, the lens mounting frame moves to the hanging position where it is in use.

[Embodiments] Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

1 to 7 show an embodiment of the present invention,
Fig. 1 is a plan view showing the folded state, Fig. 2 is a plan view showing the use state, Fig. 3 is a side sectional view showing the connecting body and the upper frame portion, and Fig. 4 shows the use state in the right half. Plane sectional view showing the right half in the folded state,
FIG. 5 is a front sectional view showing the left half in a used state, the right half in a folded state, FIG. 6 is a perspective view showing the guide groove portion, and FIG. 7 is an exploded perspective view showing the operating section.

As shown in FIGS. 4 and 5, the upper frame 1 has a cylindrical shape with a hollow 2, and a horizontal arm 3a of a support piece 3 having a shape in plan view is slidably arranged in the hollow 2. and
Further, at the end of the vertical arm 3b of the support piece 3, a temple 4 is rotatably provided via a hinge 4a, as shown in FIG. A receiving portion 8 that rotatably supports a portion of a connecting body 6 fixed to a portion of the lens mounting frame 5 by means of a pin 7 protrudes from the side arm 3a of the support piece 3 in the hollow 2. be done. Furthermore, an engaging pawl 9 is formed at the tip of the side arm 3a disposed within the hollow 2 of the frame body 3, so that it can be engaged with and disengaged from a locking pawl 11 of an operating section 10, which will be described later.

The operating portion 10 is fixed at the center of the hollow 2, and as shown in FIGS. 4, 5, and 7, has a T-shape in plan view, and has a central hole 12a and a lateral groove 12b. The block body 12 is inserted into the horizontal groove 12b of the block body 12 so as to be retractable.
The engaging claw 11 is urged to contact the inner wall of the upper frame 1 by receiving the elastic force of the spring 13 built in the central hole 12a, and the engaging claw 11 is fitted into the engaging claw 11 and is It consists of an operation button 14 that partially projects from the upper frame 1 so that the engaging claw 11 can be moved from outside the upper frame 1.

Further, a plurality of female screws 15 are carved in both ends of the hollow 2, and a small screw 16 is screwed into one of the female screws 15 through the upper frame 1, so that the upper frame 1 is connected to the upper frame 1. A fixed stopper body 17 is provided, and the inner surface of the stopper body 17 and the receiving portion 8 come into contact with each other, thereby regulating the distance by which the support piece 3 extends outward. That is, the stopper body 17 can be moved in the left and right directions in FIG. The distance between the pair of lens mounting frames 5 is adjusted.

A spring 18 is interposed between the foot portion 12a of the block body 12 and the receiving portion 8 of the support piece 3, and the spring 18 always urges the support piece 3 outward. As shown in FIG. 6, the lens attachment frame 5 is latched to the upper part of the neck 6a of the connecting body 6, and the lens mounting frame 5 is suspended downward, that is, as will be described later, so that the glasses can be used. It is biased in the direction.

Further, as shown in FIG. 6, a guide groove 19 is formed in the upper frame 1 of the connecting body 6 portion. This guide groove 19 is formed continuously so that a lower part 19a exists near the inner edge of the upper frame 1, and an upper part 19b exists near the center.
As shown in the figure, when the connecting body 6 is positioned above the guide groove 19, the lens mounting frame 5 becomes parallel to the extending direction of the temple 4, and when the connecting body 6 is positioned below the guide groove 19, Lens mounting frame 5
is made to hang down to the upper frame 1. In this way, the connecting body 6 and the guide groove 19 serve as means for regulating the positional movement of the lens mounting frame 5.

Therefore, when the glasses are not in use, when the side arm 3a of the support piece 3 is pushed into the upper frame 1, the engagement claw 9 of the support piece 3 engages with the locking claw 11 of the block body 12, and the support piece 3 is held in the shortened state by the upper frame 1. When the above-mentioned support piece 3 is pushed in, the connecting body 6
is raised along the guide groove 19 centering on the pin 7 and against the elastic force of the end portion 18a of the spring 18, thereby making the lens mounting frame 5 parallel to the extending direction of the temple 4. When the temple 4 is rotated relative to the support piece 3, the lens mounting frame 5 is positioned within the frame formed by the upper frame 1, the support piece 3, and the temple 4, as shown in FIG. This means that the glasses frame can be folded to become thinner as a whole.

Next, the operation of shifting from the non-use state to the use state will be described below.

Rotate the temple 4 around the hinge 4a,
When the vertical arm 3b of the support piece 3 is aligned with the vertical arm 3b and the operation button 14 is then pressed, the engaging claw 11 is pushed inward of the hollow 2 against the elastic force of the spring 13. At this time, the engagement between the engagement claw 11 and the locking claw 9 is released. Then, the horizontal arm 3a of the support piece 3 is connected to the spring 1
8 moves to the end of the upper frame 1,
The support piece 3 is held by the upper frame 1 where the stopper body 17 and the receiving part 8 come into contact.

During the movement of the above-mentioned side arm 3a, the connecting body 6 is guided so as to be moved from the upper part to the lower part of the guide groove 19. Furthermore, since the connecting body 6 receives a downward biasing force from the end 18a of the spring 18, it rotates around the pin 7 and is forcibly moved to the lower part of the guide groove 19. Then, the lens mounting frame 5 fixed to the connecting body 6 is rotated to the hanging position, which is the operating state, with respect to the upper side frame 1, and in this state, the lens mounting frame 5 is attached to the end 1 of the spring 18.
It is held in the hanging position by the elastic force of 8a.

In the above embodiment, the regulating means for moving the lens mounting frame 5 to the folded state or the hanging state is constituted by the connecting body 6 provided on the lens mounting frame 5 and the guide groove 19 formed on the upper side frame 1. However, a screw thread or a twisting part is formed on the side arm 3a of the support piece 3, and the screw thread or twisting part converts the pushing force of the support piece 3 against the upper frame 1 into rotational force. It is also conceivable to rotate the lens mounting frame 5 to the above-mentioned state.

Further, as another example of the stopper body 17 that restricts the movement of the support piece 3 described above, the stopper body 1
It is also conceivable to form one female thread 15 on the upper side frame 1 and form a plurality of insertion portions into which the machine screws 6 can be inserted.

[Effects] Since the present invention is constructed as described above, the glasses frame can be easily changed from a used state to a flat and thin non-used state, and vice versa, by moving the support piece in and out of the upper frame. can be provided.
