Description

  The present invention is a significant evolution of Patent No. 3924686 (glasses frame without hinges), utility model No. 3139414, (overopening stop (armor)) and temples.

Along with the change of the part name (named as an over-opening stop in utility model No. 3139414), the part position is firmly established as an armor in the industry. Will be changed.

The outline of the frame without the hinges is made with a pair of plastic lenses with edge glasses.
To fix the lens, a groove is cut around the lens instead of a hole, and a fixed line is stretched around the groove and fixed to the bridge. The temple is opened and closed around the fixed line (registered).

Patent No. 3924686, patent name, glasses frame without hinges

Utility Model No. 3139414 Over-opening Stopper

With regard to the patent No. 3924686 and the utility model No. 3139414 acquired earlier, the drawings up to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5 have already been registered in the patent and utility model. (Drawings added as necessary for explanation)
However, the eyeglass frame without the patent name and the hinge did not have the essential requirement of the forward tilt angle required for the eyeglass frame and could not be commercialized.

  The patent No. 3924686, patent name “glasses frame without hinges” has an unprecedented structure in the past, but has no forward tilt angle, and it was an urgent task to create the forward tilt angle.

  According to the present invention, it was possible to provide a forward tilt angle to the glasses frame that did not have a hinge. The conventional glasses frame shared the forward tilt angle with the armor and the opening and closing with the hinge. However, the glasses frame has no hinge. It took a long time because it was difficult to provide the two functions of opening and closing and the forward tilt angle in a single armor (equivalent position).

Means for Solving the Invention

Eyeglass frame / Temple opening / closing integrated armor with forward tilting angle FIG. 6 of the temple opening / closing integrated armor with forward tilting angle is an assembled view, and a front plate (2-1) and a small box (2-2) are joined to the rear. The temple (3-1), which is formed as a unitary body, is provided with a cam (3-2) on the inner side near the tip, and the cam is provided with a hole (3-3) for receiving a pipe. The swing pipe (3-4) has a constricted shape at the center.
(1) Armor having an inclination angle and (2) Connecting a temple with a cam (3) Three points of a swing pipe are combined to form a temple opening and closing integrated armor with a forward inclination angle.

  A temple-opening integrated armor with forward tilt (hereinafter referred to as armor) is a combination of the front plate (2-1) and the rear box (2-2) in the shape of a box at the rear. Inclination angle (2-3AB) FIG. 7 is provided with grooves (2-3A) (2-3B) for fitting the temple cams (3-2) into a curved surface, and FIG. Is provided with a landing (hole) (2-5) that allows the pipe to move up and down along the back of the front plate at the center of the box, and is fitted into a lens notch (4-4) at the bottom of the box 9 (2-4) portion (fitting allowance) having a width and height for this purpose is provided, and further, a fixing bolt (2-6) for fixing the lens after fitting into the lens is provided behind the bottom portion.

  In the armor of FIG. 11 (3-1) of the armor, the half-moon shaped cam (3-2) on the back side closer to the tip is aligned with the inclination angle (forward inclination angle) of the armor. The cam (3-2) is provided with an inclined angle, and the pipe (3-3) is provided with a pipe mounting hole (3-3) in the center and rearward (FIG. 11), and the pipe inserted therein freely swings. Opening (3-3AB) is provided at both ends of the cam hole for easy operation. Further, when the temple is closed due to the provision of a forward tilt angle, the temple becomes a downward X-shaped intersection. Therefore, the bent portion of the front portion of the temple is twisted inward by an amount corresponding to the forward tilt angle to form an X-shaped intersection. I will cancel.

  A tip ring (3-4B) attached to the tip after passing through the cam hole in FIG. 13 (3-4A) and the swinging pipe for combining the armor and the temple and opening and closing the temple smoothly. The appearance of the swing pipe has a constriction at the center, and the pipe can be swung after it is placed in the hole of the temple cam (hereinafter referred to as a pipe). An opening (3-5AB) is provided so as not to damage the fixed wire passing through (3-5) (Fig. 13).

  Assembling an armor with a built-in temple opening and closing with a forward tilt ・ Fitting the cam of the temple of “0011” into the groove of the armor of “0010”, then the pipe of “0012” (3-4A) to the landing of the armor (hole) , From FIG. 10 (2-5), insert into the hole (3-3) of the combined cam, and insert the tip ring (3-4B) from the landing (hole) (2-5) on the opposite side, The pipe (3-4A) is widened so that the tip ring (3-4B) does not come off the pipe (3-4A). Since it is made up of two lenses and the left and right relations are made in the opposite direction, what is the forward tilt angle mentioned above? Let me tell you that it exists for the other lens.

About the box washer ・ The box washer is a part that mounts the armor on the lens, and has a square-shaped edge (2-7) in FIG. 14 and uses the opening (2-7B) outward. To do.
The armor insertion portion (2-4) is inserted into the notch (4-4) on the outer side of the previously completed lens, and the opening (2-) of the box washer is inserted into the rear bolt (2-6) of the armor. 7B) is faced outward and fitted into the bolt, and fixed with the nut (5-1) and cap nut (5-2). The edge of the box washer firmly presses around the lens notch.

  FIG. 15 L-shaped washer is an improved part on the bridge side, L-shaped horizontally long, with a bulge in the center and a hole (1-4C) through which the lens fixing bolt is passed, and the front lens contact surface is made smooth, The rear part (FIG. 15) is made of an elastic material so as to cover the lens receiver (1-2) without damaging the lens (hereinafter referred to as L-shaped seat). After using the armor to the lens, the fixing line is passed through the pipe hole (3-5) of the armor, along the groove around the lens, and connected to the hole (1-2AB) of the lens receiving plate of the bridge. After fitting the recess (4-3) inside the lens to the lens fixing bolt (1-3) of the bridge, use the L-shaped seat and fix it with the nut (5-1) and the cap nut (5-2) To do.

Effect of the invention

A pair of lenses (4) on the bridge side is a combination of the lens recess (4-3), fixing bolt (1-3) and lens receiver (1-2). It is sandwiched between the rear end of the bridge and the end of the L-shaped washer (1-4A), and the lens is not fixed.
On the temple side, the armor is fixed to the lens, but the temple opens from the half-opened position while gradually extending the fixing line, and stops at the open position up to the V shape. Because the lens is loaded for the first time, even if it opens more than the face width when worn, the temple is an opening and closing in the landing area of the armor and does not apply any load to the lens.

  It is a strong spectacle frame. The load from the side when worn is absorbed by the temple, and the front and rear impacts are absorbed by the sandwiching between the tip of the bridge and the tip of the L washer, and the upper and lower loads are received by the lens receiver (1 -2) and the lens fixing bolt are combined with the lens recess, and the fixing line expands and contracts around the lens recess to absorb the load of the lens holder and prevent the astigmatic lens from rotating.

  The eyeglass frame is comfortable to wear.-The eyeglass frame has a soft structure, the temples open and close truly smoothly due to the landing of the pipe insertion hole on the side, etc., and exquisite wearing using the expansion and contraction of the fixed line around the lens. You can get a feeling, and it is also a feature that there is little slippage.

The frame material can be chosen.-The temple material can be lightly worn even if metal, celluloid, bamboo, etc. are used.

  For safety ・ This eyeglass frame is equipped with a temple opening and closing integrated armor with a forward tilt angle, so that the eyeglass frame has both ends of the pipe attached to the temple cam paired with the armor from the armor. Even if the fixing line that passes through the pipe without breaking is cut off, the armor is firmly fixed to the lens, and on the bridge side, it is sandwiched between the back of the bridge tip and the L-shaped washer, and the shape of the glasses is maintained. It is safe to use for a while until maintenance. Especially when driving a car.

Processing errors have been reduced ・ Evolution of the armor (Temple opening and closing integrated armor) ・ Glasses frames without hinges have further reduced processing errors.
With conventional hole-opening eyeglasses, the screw hole position of the lens does not reach the inner side, and the outer side can rattle the frame, but it is easy to use expensive equipment, but it is difficult to spread it to a lot of times, It also increases the cost.
The eyeglass frame is grooved around the lens, but with the widespread use of nyroll eyeglasses, the grooving device is prevalent and I think it is easy to grooving.
In addition to grooving, this eyeglass lens has a dent on the inside of the lens and a notch on the outside, but in recent years with the advent of high-performance lens processing machines, this lens processing can be easily processed, Since the widespread use of high-performance lens processing machines does not go on and off, we have created a simple cutting machine with a palm size that is simple and free of processing errors.

Since the glasses frame without hinges is a frame frame, you can make the lens shape and lens size completely freely.
Therefore, the manufacturer does not make various types according to size, and does not make wasteful size, and as a result, secure profit can be secured.
In addition, we don't have to worry about distantly selling sizes in eyeglass stores, and we can deal with customers with a variety of glasses from original designs, sizes, dyeing, etc. and a small amount of frames, so we eliminate excessive inventory and waste I can

Industrial applicability

In general, although the conventional spectacle frame has made significant progress in the material, the structure of each part is a fixed type, so-called rigid structure.
In comparison, the eyeglass frame without this hinge has a soft structure that absorbs shocks on both the bridge and temple sides.
The hinge-free eyeglass frame can be used from plasticizers to precious metals, bamboo, hard wood, etc., regardless of the material. Is possible.
Because there was an unprecedented structure, there was an opinion that adjustment at the spectacle store stage was difficult, so we suddenly devised a “palm-sized lens processing device” and added that it can be provided in parallel, plus I hope that the eyeglasses can be made freely in both design and size at the stage of eyeglasses, and that communication with the end consumer will be expanded and helped to revitalize.
