Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is directed to eyeglass frames made of a material other than metal, and relates to a pattern formed on the eyeglass frames.

(Prior art) Metal eyeglass frames are made of materials with high tensile strength and excellent spring characteristics, and are extremely slim frames. The outer surface of the frame is plated, painted, or sometimes has a decorative board formed by applying paint containing epoxy resin and pigments.

However, on the other hand, the decorative forms of eyeglass frames made of materials such as nylon and plastic are limited compared to the above-mentioned metal eyeglass frames, and it is not possible to form particularly fine patterns or designs. For example, it is possible to print on the outer surface of a nylon frame, but it is difficult to form a delicate printed pattern, and the ink film a attached to the surface due to printing is slightly smaller than the surface b. However, as shown in FIG. 7, it is in a protruding state. Therefore, ink film a that protrudes due to contact and friction in daily life.
will inevitably wear out, and the corners of the pattern formed will disappear. On the other hand, a transfer method is known in which a predetermined pattern is formed by wrapping a film with ink attached to the outer surface of the frame and allowing the ink from the film to penetrate into the frame in an atmosphere heated to a high temperature. It is widely used in the frame industry. However, in the case of nylon and plastic frames, which are the subject of this invention, the materials cannot withstand high heat, so not only is it not possible to form patterns using this transfer method, but the patterns obtained by this transfer also cannot be formed. It is well known that the pattern is blurred and the pattern is not delicate or clear.

(Objective of the Present Invention) As described above, decorative means for eyeglass frames made of materials other than metal, such as plastic and nylon, are limited, and it has been difficult to form delicate and clear patterns. The present invention is a technology devised to solve these problems, and is a technique that uses glasses frames made of plastic, nylon, etc., especially frames with unprecedented delicate and indelible patterns on the inner surface of the temples. It is to provide the vines of

(Structure of the present invention) The pattern of the decorative body according to the present invention is not only formed by applying ink to the outer surface, but also by partially forming a rough surface on the outer surface. A pattern, design, or letter that can be seen by the human eye due to the diffused reflection of light caused by the light. That is, if the rough surface is formed with a predetermined contour, a kind of pattern will be formed.

By the way, the formation of the rough surface is a sanding method that has been conventionally used in various fields.A prescribed sheet is attached to the surface to be processed, and glass powder or steel stone is crushed from the top of the sheet. The powder is sprayed at a high speed, and the powder is struck against the frame surface only in the holes previously formed in the sheet, thereby roughening the surface. Therefore, the sanded portion not only has a rough surface, but also has a shallow concave shape, and the concave bottom is roughened. A predetermined pattern or the like is punched out on the sheet that is pasted onto the frame surface before sanding, and the sheet can be pasted at an appropriate location. The present invention also includes patterns and designs formed by applying paint with a predetermined color to the concave bottom, and in this case, the paint is applied as is after sanding. do it.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the temples for glasses frames according to the present invention will be described in detail below with reference to the drawings.

(Example) Fig. 1 shows a general eyeglass frame made of plastic or nylon, and the frame consists of a front frame 1 and a temple 2, and the temple 2 is attached to both sides of the front frame 1 via hinges 3. They are connected so that they can be opened and closed. The front frame 1 has two frames 5, 5 for fixing the lenses 4, which are integrally formed symmetrically through a connecting part 6, and nose pads 7, 7 are also formed on the frame 5 below the connecting part 6. It is integrally formed. And these front frames 1
and the crane 2 are made of a non-metallic material such as plastic or nylon; however, the hinge 3 is made of a metal material in order to open and close the temple 2, and each butterfly piece 3a, 3b is embedded in the front frame 1 and the temple 2, respectively. It is fixed to metal fittings 8 and 9.

By the way, FIG. 2 shows an enlarged longitudinal cross-sectional view of the inner surface 13 of the temple 2. A shallow recess 11 is formed in the inner surface 13, and the bottom 12 of the recess 11 is very deep. It has a rough surface with fine irregularities. Since the recess 11 has a predetermined shape, the rough surface is displayed on the inner surface 13 as a kind of pattern or letters.
That is, although the bottom 12 of the recess 11 is not coated with a certain color of paint, the surface of the vine 2 is a polished smooth glossy surface, and there are some areas within such a smooth surface. Unlike other surfaces, the formed rough surface reflects light diffusely and appears as a pattern in a predetermined shape.

Incidentally, such eyeglass frames made of nylon or plastic are made of at least a semi-transparent material, and the temple 2 generally has a metal core (not shown) embedded therein in order to increase its bending rigidity.
Therefore, since it is semi-transparent, the core bar embedded inside the temple 2 is obvious from the outside, and the pattern formed on the inner surface 13 will be obstructed by the core bar. Therefore, the above-mentioned core bar is not embedded in the eyeglass frame temple 2 according to the present invention.
Therefore, in order to increase the bending rigidity equivalent to the embedding of the core metal, the thickness, particularly the thickness, of the temple 2 is increased.
However, if the pattern is not formed on the temple 2 by forming it on the front surface of the front frame, it is free to embed the core bar in the conventional manner.

FIG. 3 shows a cross section of the vine 2. In this case, the pattern formed on the inner surface 13 passes through the inside of the translucent vine 2 (particularly the nearly transparent vine 2), and from the outer surface 10 side. fully recognized. Furthermore, the outer surface 10
A C-plane 14 is formed on the C-plane 14, and the pattern on the inner surface 13 becomes clear from the direction of the C-plane 14 due to the bending of light.

By the way, to form a pattern by roughening the surface, a sheet 15 is attached to the inner surface 13 as shown in FIGS. 4a and 4b. The sheet 15 is punched with holes 16 having a predetermined pattern.
5 If sand is poured from the top surface, the sand hits the inner surface 13 only at the hole 16, as shown in FIG. 4b.
A recess 11 is formed on the inner surface 13, and the bottom 12 of the recess 11 is a rough surface. Here, the type and form of the sheet 15 is not limited, and any sheet 15 that can be sanded can be used; for example, the sheet 15 shown in FIG. 5a can be used. The sheet 15 is composed of each layer of a support 17, an auxiliary body 18, a film 19, and a protective paper 20, and the film 19 has holes 16 formed with delicate patterns/designs (see Fig. 5a). ). Therefore, the protective paper 20 is peeled off and the inner surface 13 is removed.
(Figure 5b). Support 1 as shown in c
7 is peeled off and sanded (Fig. 5 d). The auxiliary body 18 is damaged by the sand driving process, and the blown sand enters the hole 16 and destroys and removes the inner surface 13, forming a recess 11 as shown in e, and the bottom 12 of the recess 11. exhibits a rough surface.

Also, Fig. 6 shows the recess 11 formed by sand hammering.
The bottom 12 of the sheet 15 is coated with a paint having a predetermined color to form a paint film 21. In this way, the sheet 15 can be used as is to apply the paint.

As mentioned above, the temples of the glasses frame according to the present invention are made of semi-transparent nylon, plastic, etc. other than metal, and are formed by sanding into the recesses with rough bottoms on the surface. Also, a predetermined pattern is created by applying paint to the recessed portion, and the following effects can be obtained.

(Effects) Decorative methods for eyeglass frames made of plastic or nylon were extremely limited, but even when the surface is roughened by sand hammering, the patterns formed are extremely delicate and clear. possible,
It can give a novel image that cannot be seen in conventional plastic frames, etc., and since the concave part formed on the inner surface also shows a pattern, the pattern will never disappear or the corners will become blurred. There isn't. This is the same when a coating film is formed on the bottom of the recess, and more diverse images can be provided.

The pattern can also be seen from the outer surface of the vine, and by forming a C surface at the corner of the outer surface,
There are various decorative modes, such as being able to be seen from the C-plane by utilizing the bending of light.
