Description

[Detailed Description of the Invention] [Technical field of the present invention] The present invention relates to folding half glasses.
In detail, when using it, it is placed comfortably on the wearer's komekami part and nose part and it is comfortable to wear. The present invention relates to folding half-glasses having a lens protection function that works in a complementary manner with a provided cushioning pad to skillfully protect a scratch-resistant claw-eye lens.

[Conventional technology and technical problems to be solved]

For reading glasses that are not worn all the time, but worn only during work such as reading and writing, they should be as compact as possible because portability is required, and that they are comfortable to wear when worn. is necessary. For this reason, small spectacles with half or less vertical width of the lens called half spectacles or "kanime" (crab eye) have been widely used, and recently folding spectacles have been marketed. Is coming.

By the way, the conventional folding glasses (six-fold glasses) have a drawback that the folded ear hanging temple hits the lens and damages the lens. To solve this, the folding mechanism of the ear hanging temple is used. Has come to some suggestions. The proposal is, for example, Jikho Sho 60-41044.
As in "Temple Folding Mechanism for Six-Fold Glasses" disclosed in the publication, the temple is bent at the center between the rims that are folded with the eyepieces facing each other, and the folded end is placed on the upper edge of the Klings pad. By placing it on the bridge, rim, and bracket, a stable box frame structure can be formed, and the left and right rims such as the “six-fold glasses that can be easily folded” disclosed in Japanese Utility Model Publication No. 62-3782. Is connected by a bridge having a biaxial hinge function, the center is hinge-connected to the left and right ends of the bridge, and a coil spring is arranged at a required portion so that the coil can be bent.

However, in all of these proposals, the length of the temple reaches the ear, and the lens size is intended for ordinary glasses, and the length of the lens is less than half and the length of the temple = sandwiching arm is half. The work is too delicate for half eyeglasses, and is practically inapplicable. Therefore, as for half glasses, the front frame and the temple as disclosed in Japanese Utility Model Publication No. 62-2581 are configured to be extendable and contractible so that the front frame and the temple are reduced to a minimum when carrying the device, and the front frame and the temple are worn when using. A "stretchable spectacle frame" that can be stretched and used according to the size of the wearer's head has been proposed and is now on the market. However, no matter how expandable or contractable it is, there is a limit to the reduction size due to restrictions on the component size, and it cannot be made as compact as half the size like a folding type.

The present invention has been made in view of the above-mentioned current situation in the six-fold glasses and the telescopic half glasses, and does not damage the lens,
On the contrary, not only can the front frame and the sandwich arm be folded in a form that protects from damage, but it goes one step further, and when it is used, it can be put on by putting a stable fit on the wearer's komekami and nose. SUMMARY OF THE INVENTION It is a technical object to provide typical folding half glasses.

[Means adopted for solving the problem]

Means adopted by the present inventor to solve the above technical problems will be described below with reference to the accompanying drawings.

That is, according to the present invention, the left and right rims 11 are provided for holding the crab-eye lens L having a small vertical size, and the hinge 13 is provided at the center of the bridge 12 for connecting and integrating these left and right rims 11. And a crab-shaped front frame 1 which is foldable to the eyepiece side; and has a length of approximately half the width of the crab-shaped front frame 1.
The left and right ends of the crab-shaped front frame 1 each have a pair of left and right wide frontal side clamping arms hinged to the eyepiece side so as to be foldable; and inside the free ends of these clamping arms 2. And a pair of left and right rubber-like cushioning pads 3 having a required thickness, which are mounted to face each other, said cushioning pads 3 being on the frontal side when the crab-shaped front frame 1 and frontal-side clamping arm 2 are in an expanded state. Each of the left and right rims 11 is folded on the eyepiece side so as to be able to make a buffer contact with each other, and the sandwiching arm 2 is folded to the outer surface side of the folded left and right rims. The cushioning pads 3 collide with each other below the bridge 12, and the sandwiching arm 2 is held in a separated state so as not to contact the left and right crab-eye lenses L, and the sandwiching arm 2 is held.
The technical problem described above has been solved by adopting the mechanical means that the claw-shaped lens L is configured to be widely protected over the width of the.

〔Example〕

Hereinafter, the present invention will be described in more detail with reference to the embodiments shown in the accompanying drawings. 1 is a front perspective explanatory view of half glasses which is an embodiment manufactured by applying the present invention, and FIG. 2 is a perspective explanatory view of a front frame of the same glasses which is bent at a right angle. Fig. 3 is a plan view of the front frame folded until the eyepiece sides of the left and right rims face each other, and Fig. 4 folds the sandwiching arm along the outer surface of the folded left and right rims to abut the cushioning pads at the free ends. The plan view in the opened state, No. 5
FIG. 6 is a side view of the half glasses of FIG. 4 viewed from the bridge side, and FIG. 6 is a front view of the same.

In the drawing, what is indicated by reference numeral 1 is a crab-shaped front frame, and symmetrically provided with a rim 11 holding a claw-lens L for presbyopia whose vertical size is about 1/3 of the horizontal size. ,
Moreover, these rims 11 and 11 are bridges having hinges 13.
It is possible to fold it to the eyepiece side by 12.

Reference numeral 2 designates a wide frontal-side clamping arm for clamping the frontal side of the wearer, which is made of a metal strip having slits in the longitudinal direction and having a good spring property. Has been done. The sandwiching arms 2 are rotatably supported by L-shaped hinge connecting portions provided at the left and right ends of the crab-shaped front frame 1 and can be folded inward.

What is indicated by reference numeral 3 is a thick silicone rubber cushioning pad symmetrically mounted inside the free end of the sandwiching arm 2 (FIG. 3).

The outline of the half glasses of the present embodiment is as described above,
At the time of use, the crab front frame 1 and the sandwiching arms 2.2 are expanded, and the cushioning pads 3.3 at the left and right ends of the sandwiching arms
If you place it on the left and right side of the wearer's own side and pinch it from both sides and place the nose pad below the bridge 12 on the side of the nose, you can freely read, write and do other detailed work like normal reading glasses. It can be performed.

On the other hand, when carrying the half glasses of this embodiment, first, the left and right rims 11 and 11 are folded on the eyepiece side, and the sandwiching arms 2 and 2 are folded to the outer surface side of the folded left and right rims. Since the buffer pads 3 and 3 attached to the free ends of the arms are made thick, the separated state is maintained without contacting the crab-eye lenses L and L fitted by the folding of the rims 11 and 11. As a result, the two arms 2 and 2 collide with each other in a buffer manner below the bridge 12, and the sandwiching arms 2 and 2 are in a posture of broadly protecting the crab-eye lens L on their side surfaces.

[Effect of the present invention]

As described above with reference to the embodiments, the half eyeglasses manufactured by applying the present invention are provided with cushioning pads attached to the free ends of both sandwiching arms when the sandwiching arms are folded to the outer surface side of the folded left and right rims. Since they collide with each other under the bridge, the arm itself does not contact the crab lens at all, so not only does it have no harmful effect on the lens, but on the contrary, the side of the pinching arm has crabs. The lens L can be broadly protected.

Further, in the half glasses of the present invention, the rubber-like cushioning pad attached to the free end of the eyeglasses properly clamps the wearer's komekami part when worn, so that the nose pad of the front part is worn. It fits stably on the nose of the person and the comfort is very good.

As described above, the present invention can solve the problems of lens damage, uncomfortable wearing, and troublesome folding operation, which have been inevitable in this type of half glasses, and do not complicate the structure structurally. Therefore, it can be provided at low cost, and there are great advantages both practically and economically.
