Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component of a spectacle frame made of bamboo, and a spectacle frame formed by using the component. Here, the eyeglass frame to which the present invention is applied includes a frame formed of a half rim and a frame for frameless eyeglasses having no rim.

[0002]

2. Description of the Related Art In general, metals and resins are used as materials for eyeglass frames, and sometimes eyeglass frames composed of a combination of metals and resins are actually used. In the case of metal eyeglass frames, thin and slim frames are manufactured to take advantage of the characteristics of the material.Especially, eyeglass frames made of titanium material, which is light and has excellent spring properties, are the mainstream of metal eyeglass frames in recent years. Has become.

[0003] On the other hand, in the case of a resin eyeglass frame,
Due to its material strength, it is not possible to make a thin and slim eyeglass frame like metal, but it has good skin contact when hung on the face, and the manufacturing cost is compared because it is made by injection molding It has the advantage of being cheaper. Of course, even if it is made of resin, its type is diversified, and recently, a frame having a spring property (elasticity) similar to metal has been developed.

[0004]

As described above, metals and resins are mainly used as materials for conventional eyeglass frames,
Each has its own characteristics. The present invention provides an eyeglass frame and parts thereof made of bamboo, which is a material completely different from conventional materials.

[0005]

The components of the eyeglass frame of the present invention use bamboo as a material. Bamboo is a perennial plant that grows or grows in the wild in Yamano. There are many types of bamboo, such as mousoudake, madake, kurotiku, and nariyadake. Bamboo has a great influence on Japanese culture since ancient times, and there are many ornamental bamboo forests in Japanese gardens. Building materials made of bamboo,
It is used in various places such as musical instruments, crafts, bows and arrows.

The parts of the eyeglass frame according to the present invention are made of this bamboo. The bamboo is sticky and light, so that it can be used as a material for the eyeglass frame. Therefore, when processing a bamboo into a predetermined shape to form a part, on the other hand, there is a case where it is constituted by laminating thin plate materials, and when forming a laminated structure, a plurality of thin plates are bonded to each other, screwed, or Fixed by swaging.

Although bamboo is light and has excellent spring properties, the strength is increased and the spring properties are further improved by forming a thin layer of thin plates as described above. Here, when laminating the thin plate, the fiber direction of the bamboo is arranged in the same direction,
It is not a laminated structure in which the direction is different from that of a veneer plate. The bamboo parts cover all parts, such as front frames, vines, yoroi, and nose pads (butterflies). In particular, for nasal pads, vines, and moderns that come into direct contact with the skin, it is better to use the flesh side rather than the outer skin side as the contact surface to promote sweat absorption. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0008]

FIG. 1 shows an eyeglass frame according to the present invention.
The material is bamboo. Its shape is similar to that of the conventional plastic eyeglass frame, and it consists of a front frame 1 and a crane 2, and the front frame 1 is connected to the rims 3, 3 on which the lens is fitted and the rims 3, 3. The front frame 1
The vines 2 and 2 are mounted on both sides of the vehicle so as to be foldable via hinges.

Here, the eyeglass frame shown in FIG. 1 is merely a specific example, and for example, as is often used as a general form of a metal frame,
It is also possible to use a connecting member for connecting 3 as a separate part, or to attach a roughly L-shaped yoke to both sides of the front frame 1 as separate parts, and to connect the crane 2 to this yoke. In this case, individual bamboo parts are separately processed.

The front frame 1 is made of a material obtained by cutting a cylindrical bamboo into a flat plate and cutting it into a predetermined shape. One of the methods is to use a laser beam or a water jet. Can be used. By moving while irradiating the laser beam, it can be cut into the shape of the front frame 1. Although laser processing is a conventionally known method, bamboo has a high fibrous quality and is brittle in one direction, so the cutting surface using a metal tool may be rough or cut. There are problems such as chipping or cracking.

In the processing method of irradiating a laser beam or jetting a water jet, no stress acts on the bamboo material, and it is possible to process even a very fine shape. Does not crack. Figure 2 shows Figure 1
The rim 3 has a fitting groove 5 on the inner periphery of the rim 3 in which a lens is fitted.
6 are formed. Therefore, in order to form the fitting groove 5 by irradiating the laser beam, a ring processed by irradiating the laser beam from the directions of both arrows along the slopes 6 and 6 is bonded.

FIG. 3 shows a front frame 1 having a plurality of plate members 7.
FIG. 3 is an enlarged cross-sectional view taken along the line AA in a case where the front frames 1a, 7b are stacked so that they are fixed in a state where they are correctly overlapped with each other.
Becomes In this case, by forming the fitting groove 5, the shape of each of the plate members 7a, 7b.
a, 7b... are separately laser-processed, or a rectangular plate material is used for the lamination.
Any of the cases in which the processed slope 6 is bonded as described above.

FIG. 4 is a specific example showing the crane 2,
The crane 2 passes through small holes 8, 8.
... is filled with resin. FIG. 5 is an enlarged cross-sectional view taken along the line BB in FIG. 4, and the holes 8, 8 are filled with a resin 9 and cured. This crane 2 is not only laser-processed in its outer shape but also laser-processed in hole 8, so that both holes 8,
No matter how thin the ribs 10 between the eight, they will not break. Further, it is also possible to form a concave portion without penetrating the hole 8 by laser processing, and to fill and cure the concave portion with a resin.

As shown in the cross section of the hole in FIG. 5, the inner surface of the hole 8 is formed with small irregularities, so that the filled and cured resin 9 does not come off. This hole 8
Is machined using a tool, the inner peripheral surface has no such irregularities and becomes a flat surface. As a result, the filled and cured resin 9 comes off from the hole 8. When irradiating a laser beam, the fibrous material of the bamboo and the soft part of the meat,
Since the same position is repeatedly irradiated, small irregularities are necessarily formed on the inner peripheral surface.

The tip of the vine is generally L-shaped so as to hang on the ear, but if it has a certain thickness, a modern inserted into a metal vine is not required. However, if the tip of the vine 2 is thin, it will be painful to put it on the ear, so a modern can be attached.
FIG. 6 shows another embodiment of the crane 2 of the present invention.
Indicates a vine to which no modern is attached, and (b) indicates a case where a modern 11 is attached to the tip. These vines and moderns come into contact with the skin when wearing glasses, but the flesh side is used as the contact surface instead of the outer skin side so that generated sweat is easily absorbed.

The vine 2 is attached to both sides of the front frame 1, and the vine 2 has hinges interposed therebetween so as to be foldable. Each hinge piece of the hinge is fixed to the front frame and the vine, respectively, but is generally screwed. An adhesive can be applied and fixed. Of course, screwing and fixing with an adhesive may be used. FIG. 7 shows another form of the eyeglass frame of the present invention, which forms a half rim, and has the same basic structure as a conventional half rim.

When the rims 3 and 3 are connected by a connecting member, not when the front frame 1 is formed integrally,
When attaching the yoke to both sides of the front frame 1, the connecting means of these components forms irregularities to be fitted to each other on each component, and when they are properly positioned, they are fixed with screws or an adhesive.

Although bamboo is light and excellent in elasticity, it may be partially chipped due to its directivity, and is impregnated with a resin to prevent such a phenomenon. That is, by immersing a part or the whole in an appropriate resin liquid, the resin liquid can penetrate along fine holes formed along the fiber structure, and as a result, the strength is improved, Can be prevented. This is, of course, the same for laminated components.

As described above, the eyeglass frame of the present invention uses bamboo as at least a part thereof, and the following effects can be obtained.

[0020]

The eyeglass frame according to the present invention is made of bamboo, and is therefore a very light frame. In the case of a conventional resin-made eyeglass frame, the weight is at least 10 g with the lens inserted, but in the case of the bamboo-made eyeglass frame of the present invention, it can be reduced to about half, that is, 5 g. This weight corresponds to extremely slim glasses made of titanium material in recent years. The appearance of the bamboo glasses frame gives a certain amount of volume, but it is lighter than it looks, so it is surprising to pick it up, and it does not feel heavy even when worn on the face, and of course it does not cause fatigue .

Since it is made of bamboo, it is gentle on the skin, so that it can be used without any problem even for allergic people, and because it can absorb sweat, there is no sticky feeling. Can be released to the outside. And the lifetime is semi-permanent. On the other hand, since it has an effect of suppressing electromagnetic waves, it is less susceptible to electromagnetic waves generated when making a mobile phone call. Another important effect is that bamboo is a natural plant and is environmentally friendly.
