Description

The present invention relates to an eyeglass frame that is thin, light, yet durable, and has a clear and colorful pattern.

Eyeglass frames are generally required to be light and durable, and conventionally metal or plastic materials have been used as the material. Titanium and aluminum are mainly used as metal materials, and nylon and polycarbonate are mainly used as plastic materials.
By the way, eyeglass frames are not limited to plastic eyeglasses, but also metal eyeglasses, which consist of a front part and both temples, and the temples are attached to both sides of the front part and can be folded via joints.

Figure 6 shows a conventional general metal eyeglass frame, in which (A) represents the front part and (B) represents the temple. ) can be folded through the joints (d) and (d) attached to the endpieces (c) and (c) on both sides.
FIG. 7 is a plan view of the glasses frame, in which (a) shows the case where the temple (b) is open, and (b) shows the case where the temple (b) is folded.

The temple (B) is attached to the tip of the approximately L-shaped endpiece (C) via the joint (D), so when the temple (B) is folded, the front part (A) and A large space (e) is formed between them. Therefore, if a folded eyeglass frame is left on the floor and a load P is applied by stepping on it, a large bending stress will act on the corner A of the endpiece (C), causing damage to the endpiece (C). Accidents such as this occur.

Eyeglasses are known that are configured to have a flexible fit without causing deformation of the temples or damage to the lenses.
That is, in glasses in which an endpiece is connected to the temple, a lens is bolted to the endpiece, and both ends of the bridge are bolted to a pair of lenses, a part of the endpiece is connected so that the coil axis is approximately vertical. The coil spring comprises at least one coil spring oriented in the opposite direction. Further, the portions of the bridge on both lens sides are constituted by at least one coil spring whose coil axis is substantially vertical.

In this way, conventional eyeglass frames have approximately L-shaped end pieces on both sides of the front part, so when the temples are folded, a large space is formed between the front part and the eyeglass frame. When an external force is applied, the armor will be crushed. In addition, the front part is not flat, as a nose pad is attached, and the thickness of the glasses frame increases when both temples are folded.
These are the problems that this invention aims to solve. Plastic glasses have a thin thickness when folded, have excellent durability against external forces, and have a colorful appearance and excellent design. Provide a frame.

The eyeglass frame according to the present invention is made of plastic, and its basic form is the same as the conventional one, consisting of a front part and two temples. The front part has a connecting part between both rim parts into which the lens fits, and has an integrated structure.
A sheet of constant thickness is used as the material constituting the eyeglass frame, and the sheet is cut into a predetermined front shape. Although the specific cutting method is not limited, it is possible to cut using a tool operated by a computer based on a program.
The temples are also cut into a predetermined shape using a sheet of a certain thickness.

The front portion and temples formed by cutting the sheet are configured as flat plate-like bodies without being curved into a three-dimensional shape. The connecting lower edge, which is provided in the center of the front part and is formed between both rim parts, is curved in a concave shape to form a nose pad, but has a three-dimensional shape so that it touches both sides of the nose. It does not have a pair of nose pads.

Also, the temples are attached to both sides of the front part via joints so that they can be folded, but there is no endpiece.
By the way, the specific material of the sheet forming the front part and temples constituting the glasses frame of the present invention is not limited, but in the case of plastic, nylon or polycarbonate is used.

The eyeglass frame according to the present invention has a flat front part and a flat temple, and both temples are attached to both sides of the front part via joints. Therefore, the glasses frame with two folded temples is thin and can be carried around by being stored in a breast pocket. There is no gap between the folded temple and the front part, so even if the glasses frame left on the floor is stepped on by foot, it will not be damaged, resulting in a durable glasses frame. .

On the other hand, the front part and temples are constructed by cutting sheet material, making the glasses frame comfortable to wear. In other words, it is possible to construct a thin and light eyeglass frame by constructing the front part and temples using thin titanium wire, but the contact area with the skin is small and the stability when worn is poor. However, since the glasses frames of the present invention are made of resin, they are comfortable to wear.

Furthermore, the flat surface formed on the front part and vine made of sheet material is large, and colorful patterns can be printed on this flat surface, making it thin and light with rich decorative properties, yet durable. It becomes a glasses frame.
The sheet material is then cut to form the front part and vine in a predetermined shape, which is processed using computer-controlled tools and is easier and cheaper to manufacture than injection molding using expensive molds. I can do it.

FIG. 3(a) is a front view and FIG. 3(b) is a perspective view of the front part of the glasses frame of the present invention. With the vine attached to the front part, (a) shows when the vine is open, and (b) shows when the vine is folded. A detailed view showing the mounting structure of the temples attached to the side ends of the front part. Rear view when two vines are folded. When a colorful pattern is printed on the front surface. A specific example showing a conventional general metal eyeglass frame. The temples are attached to the side edges of the front part. (a) shows the temples open, and (b) shows the temples folded.

FIG. 1 shows an embodiment of a front part 1 constituting a glasses frame according to the present invention, in which (a) shows a front view and (b) shows a perspective view. The front part 1 is made of plastic, and is formed from a thin sheet material having a constant thickness, and by cutting the sheet material. The front part 1 has both rim parts 2, 2 and a connecting part 3 in the center, and both rim parts 2, 2 are symmetrically connected at the connecting part 3 and are integrated.

The front portion 1 is made of a plastic sheet having a certain thickness. Using the sheet material, the front part 1 with the rim parts 2, 2 formed on both sides of the connecting part 3 is cut, and the computer operates a cutting tool based on a created program to cut it into a predetermined shape. You can. For example, there are various cutting tools such as wires, end mills, and lasers.
The sheet material is configured as a substantially flat plate-shaped front part 1 without being curved three-dimensionally, and a nose pad part 4 curved into a smooth concave shape is formed on the lower side of the connecting part 3.

By the way, as the sheet material, a light material such as metal titanium material or aluminum material can be used, but in the present invention, transparent plastic material such as nylon or polycarbonate is used.
These nylon and polycarbonate materials are hard, resilient, and hard to break.
The front part 1 is constructed as a flat plate-like body, but in the case of a front part made of plastic, it can be curved to some extent because it has particularly excellent restoring force.

FIG. 2 shows the temple 5 attached to the front part 1, (a) shows the temple 5 when it is open, and (b) shows the temple 5 when it is folded.
The glasses frame of the present invention uses a joint 6 as a means for attaching the temple 5 so that it can be folded, but does not employ brazing that requires heating. That is, if it is partially heat-treated by brazing or the like, it will locally soften and its strength will decrease.
The joint 6 consists of both butterfly pieces 7a, 7b and a shaft screw 8, and each butterfly piece 7a, 7b is fixed to the temple 5 and the front part 1 with pins 9, 9.

FIG. 3 shows an enlarged view of the butterfly piece 7a fixed to the temple 5. The butterfly pieces 7a, 7b are rectangular plates, and the plate-shaped butterfly piece 7a is fixed to the temple 5 via two pins 9, 9. The inside of the temple 5 is cut out to form a concave groove, and the butterfly piece 7a fits into this groove, and the tips of pins 9, 9 inserted into the holes penetrating from the surface are attached to the temple 5 by caulking the butterfly piece 7a. Fixed. The butterfly piece 7a is fixed without protruding from the inner surface of the temple 5 by fitting into the groove.

FIG. 2(b) shows a state in which the temple 5 is folded. The butterfly piece 7a fits into the groove formed on the inside of the temple 5, and the butterfly piece 7b fits into the groove formed on the inside of the front part 1, so that there is almost no gap between the temple 5 and the front part 1. Folds without leaving anything behind.
FIG. 4 shows a rear view when the two temples 5, 5 are folded. It has a structure that does not. That is, even when the temples 5, 5 are bent and deformed, the tips 10, 10 do not come into contact with the lenses 11, 11, and the lens surfaces are not scratched or the lenses 11, 11 are not damaged.

FIG. 5 is a specific example showing a pattern formed on the front surface of the front part 1. The front section 1, which is constructed by cutting a sheet material, has a larger surface area than a case where a thin wire is bent and formed, and therefore a clear and colorful pattern can be printed.
Since the vine 5 is also configured as an elongated plate, its surface area is large and, like the front part 1, a colorful pattern is printed.
