Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to foldable glasses which can be compactly stored by rotating a front portion about a bridge.

[0002]

2. Description of the Related Art In general, both glasses are generally folded and stored in a case. Since the vine is attached via hinges to the yoke that is brazed on both sides of the front part, the glasses removed from the face are folded around the hinges, but in this case the vine is connected to the front part of the glasses It will be in an overlapping state. Therefore, even if it is folded, its thickness is relatively large, and the case for storing is thick.

Therefore, in order to be able to fold and store more compactly, glasses that can be folded vertically as well as in the conventional direction are used. FIG. 5 shows a case where conventional folding glasses are folded. A first joint (c) is provided on the two ends (b) and (b) which are brazed on both sides of the front part (a), and a crimp is provided through a second joint (d) provided at the end of the front end.
(E) is installed.

The vine (e) can be opened and closed via a second joint (d), while the first joint (c) can rotate the tip of a two-piece split yoke (b). , At the same time crane
Turn (e). FIG. 5 shows a state in which the vine (e) turns and is folded, and the front part (a) and the vine (e),
(E) is in the same plane. Since ordinary glasses do not have the first joint (c), if the vines (e) and (e) are folded, they will overlap the inside of the front part (a). Therefore, the thickness at the time of storage is the size obtained by adding the crane (e) and (e) to the front part (a).

However, since the first joints (c) and (c) are provided on both sides of the front portion (a), the front portion (a) is particularly suitable for moving the body while wearing glasses. The first joints (c) and (c) move due to the weight of ()), and as a result, the front part (a) is inclined and sometimes tries to come off the face. Of course,
With the first joint (c), the fit of the glasses worn is not good.

[0006]

As described above, the conventional folding glasses have the above-mentioned problems. The problem to be solved by the present invention is this problem. The present invention provides foldable glasses that can be stored compactly and that are stable without the front part of the worn glasses being tilted.

[0007]

When the foldable glasses of the present invention are folded and stored in a case, they are in the state shown in FIG. 5, but the yoke to which the vine is attached has an integral structure that does not rotate. Made up of In the present invention, a shaft hole is provided in the bridge, and a shaft extending from the rim is fitted and attached to the shaft hole. Of course, the rim is folded because the shaft fitted in the shaft hole can rotate.

By the way, the bridge in which the shaft hole is formed is located at the center of the wad of the front part, and a wavy is attached to both sides of the wad, or the wavy is continuously formed in the wad. A coil spring is attached to the shaft that fits in the shaft hole, and the spring force is urged so as to return to the original state when the hand is released from the folded rim. That is, it is folded and stored in the case, but at the same time as it is taken out of the case, the front part rotates independently to the original state.
Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0009]

FIG. 1 is an embodiment showing foldable glasses according to the present invention. In the figure, 1 is a rim, 2 is a wading, 3 is a yoroi, 4 is a vine, and a wading 2 is both mayu 5,
5 are connected by a bridge 6, and the yoroi 3 and 3 are formed continuously on both sides of the wadding 2. Of course, there is also a case where the yoke 3 is manufactured as a separate part, and this is brazed to the side end of the waddle 3. A crane 4 is attached to the tip of the yoke via a joint 7 so as to be foldable.

Here, the rim 1 has a ring shape that restrains the entire circumference of the lens 8, but a half rim restraining the upper half is used, and a high-tensile thread such as a water thread is used on the lower side. In some cases. By the way, the rims 1 and 1 are attached to the bridge 6 of the wadding 2 so that they can be folded. An axis extending from the rim 1 toward the center can be fitted into the bridge 6 and rotated.

FIG. 2 shows the bridge 6 and the shaft 9 separated. The bridge 6 is a cylinder having a shaft hole 10 into which the shaft 9 is fitted. The bridge 6 has notches 11 and 11 at both ends and slit grooves 12 and 12 at predetermined positions from both ends. Has formed. The notches 11, 11 are formed in a range in which stoppers 13, 13 provided on the shafts 9, 9 and protruding from the outer periphery can be fitted and moved. That is, the rotation angle at which the shaft 9 rotates when the rim 1 is folded is regulated by the notch 11.

One of the slit grooves 12, 12 is a ring 1
This is a kind of window for fitting the shafts 4, 14 into the grooves 15, 15 formed at the tip of the shaft.
When the slits 12 are fitted, the spring rings 14 can be fitted into the grooves 15 from the slit grooves 12. The shafts 9, 9 are not disengaged from the shaft holes 10 of the bridge 6 by fitting the rings 14, 14 into the grooves 15, 15.

A coil spring 16 is wound around the shaft 9, one end of which is fitted in a fixing hole 17 provided on the outer periphery, and the other end of which is locked to the bridge 6. Therefore, if the shaft 9 rotates at the same time as the rim 1 is folded, the coil spring 16 is twisted to generate a spring force, a torque is generated to reverse the shaft 9, and if the hand is released, the rim 1 returns to the original state. Return to position.

The shaft 9 has a coil spring 16 as shown in FIG.
Is wound, but is formed as a stepped shaft 9 so that the coil spring 16 does not hinder the fitting in the shaft hole 10 of the bridge 6. Increase the outer diameter at the tip and base of the shaft 9,
This portion fits with the inner peripheral surface of the shaft hole 10 with almost no clearance, and can stably support the rim 1 without rattling.

FIG. 3 shows a case where the shaft 9 is fitted in the shaft hole 10 of the bridge 6. Rim 1 shown in FIG.
Is a state where the stopper 13 is in contact with the tip of the notch 11 and the rim 1 is stopped at a predetermined position. Even in this state, so that the rim 1 stops stably,
The spring force of the coil spring 16 is urged. If the surface of the lens 8 fitted on the rim 1 is pressed, the lens 9 is folded and the shaft 9 rotates, and the coil spring 16 wound on the shaft 9 is further twisted. 1 can return to its original position by itself.

In the embodiment, the shafts 9, 9 are fixed to the rims 1, 1 and are fitted in the shaft holes 10 of the bridge 6. The shaft 9 supports the rim 1 and the lens 8 in a cantilever state. Therefore, the shaft hole 1 of the bridge 6
A single shaft can be fitted to the 0 and the rims 1 and 1 can be screwed or brazed to both ends of the shaft. When the rim 1 is folded, it may be screwed and attached so that the screw is tightened when the rim 1 is folded.

Of course, even when one shaft is used, the coil spring is wound, the rotation angle of the shaft is restricted, and the basic structure is the same as that shown in FIG. FIGS. 4A and 4B show a case where the foldable glasses of the present invention are stored in a case. Although the case 18 is small, and particularly the thickness H is thin, since the rims 1 and 1 are folded and do not overlap with the vines 4 and 4, they can be stored in the thin case 18.

The crane 4, 4 is inserted into the case 18 in a bent state, and the rim 1, 1 stands up as shown in FIG. However, by closing the lid 19, the rims 1 and 1 are pressed and stored in the case 18. At the same time when the lid 19 is opened, the rims 1, 1 can be raised by the spring force of the coil springs 16, 16.

As described above, in the folding glasses of the present invention, the shaft attached to the rim is fitted into the shaft hole of the bridge in the center of the wad, and the coil spring is wound around the shaft to return the rim to its original state. And the following effects can be obtained.

[0020]

The folding glasses according to the present invention can be compacted by folding the vine and the rim fitted with the lens and can be stored in a small case. These folded glasses can be stored in a particularly thin case because the rims and the crane do not overlap. A coil spring is wound around the shaft on which the rim is mounted, and when the rim is taken out of the case, the rim can return to its original state by itself due to the spring force. At the same time, the rim does not rattle due to the biased spring force and is stabilized. On the other hand, the shaft provided on the rim is attached by fitting into the shaft hole of the bridge in the center of the wadding, and the vine is attached to both sides of the wadding via joints, and it has a folding structure independent of each other The worn glasses do not tilt or come off.
