Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem wherein it is difficult to prevent a spectacle frame from shifting while being worn and it is difficult particularly to hold the spectacle frame during heavy exercise or operation accompanied by vibrations, or in an environment of high temperature and high humidity. <P>SOLUTION: Surfaces of the spectacle frame and a component thereof that come into contact with the skin and hair are coated with liquid fluoride rubber to be silicon-bridged and the liquid fluoride rubber is cured to form a fluoride rubber film, thereby preventing the spectacle frame from shifting during wearing with surface characteristics of stickiness and large frictional force characteristic of gum. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a spectacle frame and parts thereof, and more particularly to a spectacle frame and parts thereof having an excellent anti-skid function.

The eyeglass frame is a member having a function of holding the eyeglass lens at a correct position on the face of the wearer, and it goes without saying that it plays an extremely important role for correcting vision.
None None

  The eyeglass frame is held by the nose and ears of the eyeglass wearer, but it is easy to slip during wearing, and the eyeglass frame is difficult to use during intense exercise, vibration work, or in a hot and humid environment. It is a place where we often experience daily shifts from the correct wearing position and struggling to maintain the position.

  As a measure to prevent misalignment of the glasses frame during wearing, it has been conventionally known that it is effective to make the skin contact portion such as the nose pad and the temple hook part difficult to slip. Attempts have been made to make it difficult to slip by forming a soft silicone resin layer on the surface of the hanging portion, and some have been commercialized.

  However, the formation of the soft silicone resin layer is performed by an injection molding method using a dedicated mold, which is very expensive and the silicone resin has a property of allowing moisture, sweat, and fat to permeate. Therefore, moisture, sweat, or fat penetrates into the silicone resin layer from the surface of the silicone resin layer during wearing, and stays between the silicone resin layer and the surface of the nose pad body or ear hook body, peeling off the silicone resin layer. It is easy to occur, and there is a problem in durability. In addition, since moisture, sweat, and fat contain dirt, if these penetrate into the silicone resin layer, the north pad and ear hook part will become dirty and yellow, which is not preferable from the viewpoint of hygiene. There wasn't.

  The present inventor has an anti-slip function comparable to that of the above soft silicone resin layer, and has excellent durability, no possibility of peeling phenomenon, prevention of dirt, and low anti-slip function. As a result of diligent research to realize an excellent spectacle frame and its parts, this was successfully realized this time and is proposed here as the present invention.

  The above problem was solved by applying a liquid fluororubber capable of silicon cross-linking to the surface of the eyeglass frame and its parts in contact with the skin and hair and curing it to form a very thin fluororubber film.

  When wearing eyeglass frames, it is possible to wear it comfortably even under intense environments such as intense exercise and vibration, high temperature and humidity sweating, by preventing the slippage due to the large surface characteristics of the rubber-like sticky friction force. Due to the chemical properties of fluorine, it prevents the penetration of moisture, sweat, and fat containing dirt into the interior, and there is no risk of peeling or yellowing and has high durability. In addition, a dedicated mold is not required at all, and it can be manufactured at a low cost, which is excellent in terms of cost.

  The greatest feature is that an ultra-thin fluororubber film is formed by applying liquid fluororubber capable of silicon cross-linking to the eyeglass frame and the parts of its parts in contact with the skin and hair.

  FIG. 1 is a perspective view of a spectacle frame according to the present invention, FIG. 2 is an enlarged perspective view of a nose pad that is one of the parts of the spectacle frame, and FIG. 3 is an enlarged perspective view of an ear hook. In the figure, 1 is an eyeglass frame, 2 is a nose pad, 3 is an ear hook connected to the temple 4, and the nose pad 2 and the ear hook 3 are both made of hard synthetic resin. And the liquid fluororubber which can carry out silicon bridge | crosslinking is apply | coated to the location which touches a wearer's skin and head hair of these nose pads 2 and the ear hook part 3 at least. The liquid fluororubber capable of silicon crosslinking is applied by appropriate means such as spraying or brush printing. After coating, the liquid fluororubber evaporates and cures the solvent contained therein, resulting in a very thin fluororubber film 5. This fluororubber film 5 has a surface property with a large, sticky frictional force, which is a basic property of a rubber-like substance, and also has chemical properties of fluorine such as durability, solvent resistance, and chemical resistance as it is. keeping.

  In this embodiment, the fluororubber film 5 is formed only on the part of the nose pad 2 and the ear hook 3 of the temple 4 that is in contact with the skin and the hair. However, the fluororubber film 5 may be formed on the entire surface of these parts or other parts. Of course, it may be formed at appropriate locations on the eyeglass frame 1.

  The spectacle frame and its parts according to the present invention have the above-described configuration. When these are worn, the spectacle frame 1 is prevented from being displaced by the thick surface characteristics of the fluororubber film 5 having a thick frictional force. The glasses frame 1 can be worn comfortably even under intense conditions of motion, vibration, and high-temperature and high-humidity sweating, and the chemical properties of fluorine can penetrate dirt, moisture, sweat, and fat into the interior. Prevents peeling and yellowing and has high durability. In addition, it does not require any special mold or the like, and can be manufactured at a low cost.

  It can be widely used not only for vision correction but also for various eyeglass frames such as sunglasses.
