Description

[Detailed description of the invention] (Industrial application field) This invention relates to parts of eyeglasses, specifically to a modern device that allows glasses to be held in the wearer's ears.

(Prior art) When wearing glasses, the part that goes over the wearer's ears,
In other words, many modern items are made of plastic.

On the other hand, Utility Model Application No. 57-184913, Utility Model Application No. 55-
A modern made of silicone has also been proposed, as disclosed in Publication No. 125614.

(Issues to be Solved) The plastic glasses that have existed in the past are not very comfortable to wear, slip easily, and tend to cause the glasses to slip off, making them unsatisfactory.

On the other hand, silicone rubber has a moderate degree of flexibility, and if a mold is made of silicone rubber, it can be expected to improve the feeling of wearing and prevent slippage, etc. Therefore, as mentioned above, silicone rubber Several modern versions have also been proposed.

However, due to its characteristics, silicone rubber is difficult to process and mold, and as disclosed in Japanese Utility Model Application Publication No. 55-125614, a special mold must be used to form the entire modern mold with silicone rubber.
It was not very practical because it required a large amount of money to make the mold and the silicone rubber itself was expensive.

Furthermore, if the entire modern was made of silicone rubber in this way, it would not be possible to provide the necessary strength to the modern, and the durability would be poor and it would be inevitable that the modern would be deformed and damaged in a short period of time.

Furthermore, if you insert a silicone rubber modern directly into a metal temple like this, the sweat that seeps through the silicone rubber little by little during use will react with the metal and cause the temple to break down. It was inevitable that the metal would corrode and the temple would turn an ugly green color.

On the other hand, as disclosed in Japanese Utility Model Application Publication No. 57-184913, a plastic core coated with silicone rubber requires less silicone rubber, but is difficult and time-consuming to manufacture. Considering manufacturing costs, this was not very practical.

Furthermore, the silicone rubber coating was easily peeled off from the plastic core, which caused problems in terms of durability.

In particular, the end surface of the modern lens near the lens, which is called the forepart, and the end surface of the modern lens, which is called the tip end, frequently come into contact with or bump into other objects when putting on and taking off glasses or during other daily use. Therefore, tears and scratches were likely to occur, and the silicone rubber coating was likely to peel off from there.

Furthermore, since the opening part is coated with silicone rubber, this part easily gets entangled with the wearer's hair.
This makes it uncomfortable to wear and gives the user discomfort when putting on and taking off.

This invention aims to solve the above-mentioned problems regarding modern glasses using silicone rubber, and it can be produced at low cost, is highly durable, feels comfortable to wear, and has a good appearance. The purpose is to provide a modern pair of glasses made of silicone that fully utilizes the characteristics of silicone rubber and is highly practical.

(Means for Solving the Problems) This invention provides that the middle part 5 of the plastic modern main body 2 has a step in which the outer diameter of the small mouth part 6 and the tip part 7 are enlarged compared to the middle part 5. A tube 3 made of silicone rubber having a wall thickness approximately corresponding to the step is covered so that the portion 6 and the tip 7 are exposed, and the outer periphery of the mouth portion 6 and tip portion 7 and the outer circumferential end of the tube 3 are covered. The purpose is to solve the above problem by configuring a silicone modern that is connected with almost no difference in level.

(Function) Like conventional glasses, glasses are held over the ears, and the part that comes in contact with the ears is covered with a tube made of silicone rubber, so the softness unique to silicone rubber provides a comfortable fit. , to prevent glasses from slipping off.

Furthermore, since the mouth and tip parts, which are likely to come into contact with or be hit by other objects, are not coated with silicone rubber, there is no risk of the silicone rubber being scratched or torn from these parts. Furthermore, although these parts often come into contact with the wearer's hair, since they are not covered with silicone rubber, hair does not get tangled in these parts.

In addition, since the outer periphery of the exposed edge and tip of this plastic and the outer periphery of the silicone rubber tube are connected with almost no difference in level, hair or other objects may get caught in the connection and may be removed from this area. There is no risk of the silicone rubber breaking and the appearance is good.

Furthermore, since the metal temples and silicone rubber are not in direct contact, corrosion of the temples due to perspiration is prevented.

(Example) Fig. 1 is a cross-sectional view of an embodiment of a silicone modern of glasses according to this invention, in which 1 is a metal temple and 2 is a plastic modern main body. has a stepped shape in which the outer diameters of the small mouth part 6 and the tip part 7 are enlarged compared to the intermediate part 5.

This intermediate portion 5 is covered with a tube 3 made of silicone rubber as shown in FIG. This tube 3 made of silicone rubber is obtained by cutting a long tube material into an appropriate length.

When the tube 5 is placed over the middle portion 5 of the modern main body 2, its outer diameter has a wall thickness that almost matches the outer diameters of the small mouth portion 6 and the tip portion 7; , so that there is almost no difference in level between the outer periphery of the edge portion 6 and the outer periphery of the tip portion 7.

The tube 3 can be easily attached to the central portion 5 by swelling the tube 3 and then inserting it into the main body 2.

The modern body 2 and the tube 3 may be of the same color, but if they are colored in different colors, the design can be more novel.

(Effects of the invention) The silicone end of the glasses according to this invention has the structure as described above, and the part of the Γ end that comes into contact with the ear is covered with a silicone rubber tube, so it has a softness unique to silicone rubber. The umbrella provides a comfortable fit and prevents the glasses from slipping off.

Γ A simple tube is used for the silicone rubber part, and there is no need to perform the technically difficult process of forming silicone rubber using expensive molds, resulting in high productivity and low raw material and processing costs.

Γ The strength is maintained by the plastic modern main body, so it has sufficient strength and is much stronger than moderns made only of silicone rubber.

Γ Since silicone rubber is not coated on the edges and tips, which tend to collide with objects or get scratched, the silicone rubber does not tear or peel from these areas, and has excellent durability.

Γ The wearer's hair will not get caught in the mouth or tip, and the wearer will not feel uncomfortable when putting on and taking off.

Γ Since the silicone rubber is not in direct contact with the temples, the temples are not corroded by sweat that has soaked into the silicone rubber, and staining and discoloration of the temples can be prevented.

Γ The middle part of the modern main body has a smaller diameter than the mouth and tip, and both ends of the silicone rubber tube and the mouth and tip touch gently with almost no difference in appearance. There is a sense of unity and nothing unnatural.

It has excellent effects such as adding aesthetic value to glasses by applying different colors to the main body and tube, and is extremely practical as it makes full use of the properties of silicone rubber.
