Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention enables fine and complex characters and patterns (for example, word trademarks, graphic trademarks, etc.) to be completely integrated with the glasses. The present invention relates to a method for displaying characters and patterns on a cored spectacle temple, which makes it possible to display them on the surface of the spectacle temple in an attractive and easy manner.

(Prior art) A metal core is embedded in the temple body that forms the outer shape of a spectacle temple8.
When displaying letters or patterns on the surface of a spectacle temple, conventionally, as shown in Figs. This was done by fitting the formed decorative body C into a fitting recess e formed in the temple body d and fixing it with adhesive. Alternatively, as shown in FIG. 1O, a decorative body C with letters or patterns attached by printing or the like is fitted into a fitting recess e formed in the temple body d, and the upper surface of the decorative body in the fitting recess e is A transparent epoxy resin g is applied to the recess f formed in the part.
The main body d is filled with resin, and the decorative body C is hung by curing the resin.
This was done by sticking to the Alternatively, this has been achieved by directly adhesively fixing the decorative body to the threaded part of the temple surface, or by stamping or printing characters or patterns on the threaded part of the temple surface.

(Problem to be Solved by the Invention) However, in the case of fitting and fixing the decorative body C into the fitting recess e, forming the fitting recess e, filling the resin, and curing the filled resin, etc. This has the problem of requiring time and effort, resulting in poor work efficiency, and thus resulting in an increase in production costs. In addition, not only the letters and patterns but also the surface of the pedestal that holds the letters and patterns appear on the surface of the eyeglass temple, resulting in the problem of weakening the impression of the letters and patterns. . Furthermore, the decorative body C, which is adhesively fixed to the fitting recess e or fixed by filling resin, is not completely integrated with the metal core (see Figures 9 and 10), so the spectacle temple is bent. There was also a risk that the decorative body C would peel off when processing to form an ear hook. Furthermore, even if it does not peel off, there is a problem in that the partially generated fftlJjl1 part spoils the appearance of the text and pattern parts. Such a problem is that while small character pieces or pattern pieces (for example, rAJ rBJ rCJ character pieces) are manufactured separately from the pedestal, fine fittings matching the shape of each of these character pieces, etc. are produced. Insertion grooves are carved into the temple surface, and then corresponding letter pieces, etc. are fitted and fixed into each of the fitting grooves, so that only the letter pieces or pattern pieces appear on the spectacle temple surface. At first glance, it seems as if the problem can be solved by doing something. However, it is extremely difficult to carve such a fitting groove with precision, and even if a fitting groove is formed, it is very difficult to fit small pieces of letters etc. into the fine fitting groove. It can be said that it is virtually impossible to display only a letter piece or a pattern piece on the surface of the temple by the method described above, since it is difficult to do so.

In addition, when the decorative body is directly adhesively fixed to the surface of the spectacle temple, as in the case where the decorative body is fixed to the fitting recess, not only the surface of the pedestal other than the letters and patterns will be exposed, but also the wall thickness will be reduced. Since the pedestal itself is exposed, there is a problem in that it is not possible to form good-looking letters and patterns, and in addition, the decorative body is more likely to peel off because the entire pedestal is exposed. There was also.

Also, when stamping letters or patterns on the surface of the vine, if the letters or patterns are large and simple in shape, it is unnecessary, but if the letters or the like are small or complex,
Formation of such character parts, etc. was “practically impossible.”

Furthermore, when letters or patterns are printed on the surface of the temple, there is a problem that they are easily worn away.

Furthermore, in each of the above-mentioned cases, when a recess is formed in the character portion or the pattern, there is also the problem that dirt adheres to the recess, impairing the cleanliness of the glasses.

The object of the present invention is to provide a method for displaying characters and patterns on a temple of glasses that can solve these problems.

(Means for Solving the Problems) A method for displaying letters and patterns on a thoughtful glasses temple according to the present invention (hereinafter referred to as a method) includes forming letters and patterns consisting of protrusions integrally on the surface of the pedestal piece 7. After brazing the decorative body 1 having the concave and convex portions 10 on the back surface of the decorative body 1 to the required portions of the front surface or the back surface of the core metal 2, the core metal 2 is
The decorative body 1 is embedded in a temple body 12 having the outer shape of a temple of spectacles, and then, by cutting a portion of the temple body 12 that faces the decorative body concavo-convex portion 10, the concavo-convex portion 10 is removed. The tip portion 16 of the protrusion is cut off, thereby making characters or patterns made up of protrusions appear on the surface of the temple.

(Example) Examples of the present invention will be described below based on the drawings. ′
1 shows the metal core 2 to which the decorative body 1 is fixed, and FIG. 2 shows the decorative body 1 together with the front part of the metal core 2.

The core metal 2 has a front portion 3 formed flat and an elongated linear portion 5 connected thereto, and a hinge piece 6 is brazed to the inner front end portion of the flat front portion 3.

The decorative body 1 has a concave-convex portion 1 formed of protruding letters of the alphabet, for example, ABC, on a surface portion 9 of a pedestal piece 7 having a rectangular plate shape and having a width substantially equal to the width of the flat front portion 3.
0 and is manufactured by means such as press working or casting.

To carry out the present invention, first, as shown in FIG. 1, the decorative body 1 is brazed to the inner surface 11 of the flat front portion 3 of the core bar 2 at its back surface. After that, a horizontally long flat temple body made of plastic, celluloid, acetate, etc. is held in a mold in a softened state, and the core bar 2 carrying the decorative body 1 is sequentially inserted from the front end of the temple body, and the glasses temple is The core metal 2 is embedded over substantially the entire length of the temple body 12, which has an external shape (see FIG. 3).

After embedding the core metal, by applying appropriate pressure to the temple body 12, the concavo-convex portion 10 of the decorative body 1 is closely integrated with the temple body 12 (see Fig. 4), and as a result, a spectacle temple as shown in Fig. 3 is formed. 13 will be produced.

In the spectacle temple 13 manufactured in this manner, when the convex tip end portion 16 of the concave and convex portion 10 is removed by cutting the portion 15 facing the decorative body concave and convex portion 10, the result is as shown in FIGS. 5 and 6. , ABC letter 17 consisting of convex parts
This results in a temple of glasses in which the inner surface portion 19 shows. Note that for the purpose of preventing corrosion, it is preferable to apply plating to the characters and pattern portions formed in this way.

In the present invention, "the core metal and the decorative body are embedded in the temple body forming the outer shape of the spectacle temple" means, in addition to inserting the core metal into the temple body as described above. It can also be achieved by dividing the upper plate and the lower plate and bonding and integrating the upper plate and the lower plate with the core bar sandwiched therebetween.

(Effects of the Invention) Since the present invention is configured as described above, even if the characters or patterns are fine or complicated, they can be neatly and easily integrated into the glasses. It can appear on the surface.

This will be explained in detail below.

(2) In the present invention, a separately molded decorative body is fixed to a core metal. Since the decorative body is formed separately from the core metal in this way, the decorative body can be
It can be easily formed with uneven parts such as fine and complicated letters or patterns by means such as press working or casting, and therefore, by cutting the temple body after inserting the core metal, These characters and patterns can be faithfully displayed on the surface of the temple.

(2) In the present invention, since the decorative body is brazed to the metal core, the letters and patterns formed by cutting the temple body are completely integrated with the glasses temple. Therefore, unlike the conventional case where the decorative body is fixed with adhesive, there is no risk of the decorative body peeling off even when the ear hook is formed by bending the temple of the spectacles. Characters and patterns can be made with excellent stability.

■ In the present invention, the tip of the protrusion of the uneven portion is removed by leaving the core metal and the decorative body embedded in the temple body that forms the outer shape of the temple of glasses, and cutting the part facing the decorative body. I am planning to do so. Therefore, unlike the conventional case where a decorative body having a concavo-convex portion formed in a concave part formed on the surface of a spectacle temple is fitted and fixed,
Because it is possible to display only the desired characters and patterns,
The characters and patterns make a strong impression on the viewer and become a scale.

Also, since the characters and patterns are revealed by cutting, the characters and patterns are flush with the surface of the temple. Therefore, unlike the conventional case where a decorative body with uneven parts is fitted into a recess or stamped to reveal letters or patterns, dirt may adhere to the letters or patterns, making it difficult to clean the glasses. There is no problem of loss of feeling. Also, unlike when printing characters or patterns, there is no risk of the characters etc. being worn out.

■ In the present invention, after a simple pre-process of brazing the decorative body to the core metal, the core metal with the decorative body formed in this way is embedded in the main body of the vine through the same process as before. The desired letters and patterns can be made to appear by simply cutting the part of the vine body that faces the uneven parts of the decorative body, making the overall work more efficient. Furthermore, characters and patterns can be formed at low cost.
