Abstract

PURPOSE:To eliminate the contact of nickel with the skin and to enable even a person having a nickel allergy to be used without worry by constituting at least the sections in contact with the skin of at least members without contg. the nickel. CONSTITUTION:The spectacle frame 1 is a general spectacle frame of a two-eye type and the metallic sections in contact with the skin are constituted of at least the members which do not contain the nickel among metals which are the sources for the metal allergy. The metallic sections which come into contact with the skin are applicable to various kinds of spectacle frame constituting members, such as temples 2, bow side ends 3, rims 4, bridges 5 and pads 6. The members which do not contain the nickel are solid metallic materials without contg. the nickel, lining materials coating the surfaces of base materials, plating coating the surfaces of the base materials, etc., for which non-metallic materials, such as resin coating films and ceramic coating, are usable. The resin coating films among these materials may be coating films of either org. or inorg. system.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spectacle frame used for, for example, eyeglasses for correcting vision, sunglasses, sports goggles, and protective spectacles for various works, and more particularly to a spectacle frame in consideration of a metal allergy.

[0002]

2. Description of the Related Art Various materials have been used for conventional eyeglass frames of this type, but metal frames are widely used from the viewpoints of strength, durability, and design. There is. Various materials are used as the metal material.

However, the selection of the material is made only from the viewpoints of strength, function, aesthetics and the like, and no one has paid attention to metal allergy.

On the other hand, recently, skin problems such as dermatitis due to piercing have become a problem, and it has been found that the cause is metal allergy. Various metals have been found to cause metal allergies, but nickel is a major cause.

Nickel is also widely used in eyeglass frames, and for people with an allergic constitution that causes a metal allergy due to nickel, it is not possible to use eyeglass frames using nickel, resulting in a narrow range of product selection. Is becoming

The present invention has been made to solve the above-mentioned problems of the prior art, and an object thereof is to provide a spectacle frame which does not cause metal allergy.

[0007]

In order to achieve the above object, in the present invention, at least a metal portion of the spectacle frame main body which comes into contact with the skin contains at least nickel among the metals serving as a metal allergic source. It is characterized in that it is configured by a member that does not exist.

The metal part that comes into contact with the skin can be applied to various eyeglass frame components such as temples, ear hooks, rims, bridges and nose pads.

The nickel-free member may be a solid metal material containing no nickel, a covering material covering the surface of the base material, a plating covering the surface of the base material, or the like.

Further, a non-metal material such as a resin coating film or a ceramic coating can be used. Of these, the resin coating film may be either an organic coating film or an inorganic coating film.

[0011]

In the spectacle frame having the above-mentioned structure, the part that comes into contact with the skin is
Since it is composed of a member that does not contain at least nickel, nickel does not come into contact with the skin and can be safely used by people with a nickel allergy.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to illustrated embodiments.

1 (a) and 1 (b) show an eyeglass frame 1 according to an embodiment of the present invention. This spectacle frame 1 is a general twin-lens type spectacle frame in which a metal part that comes into contact with the skin is formed of a member that does not contain at least nickel among the metals serving as the metal allergic source.

As the metal part which comes into contact with the skin, various eyeglass frame components such as temples 2, ear hooks 3, rims 4, bridges 5, nose pads 6 can be applied. FIG. 3 shows a rope type ear hook 31. Since the metal surface of such a rope type ear hook 31 directly contacts the skin, it is effective to use a member not containing nickel as in the present invention. Of course, a member not containing nickel may be partially provided in the eyeglass frame component.

Further, since at least the metal portion that comes into contact with the skin may be formed of a member that does not contain nickel, it is possible to configure all the metal forming portions of the spectacle frame with a nickel-free metal material that does not contain nickel.

There are various nickel-free metallic materials, for example, JIS H 3201 (brass) and JIS H 3241.
(Red copper), DIN CuZn15 (Messing 85), JIS H 373
1 (phosphor bronze), phosphor bronze for springs, various copper / tin alloys DI
N CuSn6 DIN CuSn6 DIN CuSn8, SUS 404, SUS 43
Various metal materials such as 0, SUS 410L and SUH 409 can be applied.

FIG. 1D shows an example of a single-lens type eyeglass frame. In such a single-lens type, unlike the above-mentioned twin-lens type, since it is considered that the upper edge of the rim 4 of the front part contacts the forehead and allergy is likely to occur, a nickel-free member is used as a member used in such a portion. Is effective.

Of course, the type of the spectacle frame is not limited to the example shown in the figure, and in short, it can be applied to various spectacle frames having a portion that comes into contact with the skin.

FIG. 2 shows various structural examples of members not containing nickel.

FIG. 2 (a) shows a case where a nickel-free solid metal material 101 is used in a portion in contact with the skin 100.
FIG. 2B shows the surface of the base material 102 covered with a nickel-free upholstery material 103, regardless of the material of the base material 102.
In FIG. 2C, the surface of the base material 102 is covered with the plating 104.

Further, as shown in FIG. 2 (d), a non-metal material 105 such as a resin coating film or a ceramic coating may be coated. Of these, the resin coating film may be either an organic coating film or an inorganic coating film.

In the spectacle frame having the above structure, the skin 100
Since the part that comes into contact with is composed of a member that does not contain at least nickel, nickel does not come into contact with the skin and can be safely used by people with a nickel allergy. It should be noted that in the above embodiment, only nickel was described as a metal that is a source of metal allergy, but metal allergy may occur in addition to nickel, and the type thereof varies depending on the constitution. The present invention focuses on the fact that the number of nickel allergies is large, and the site that comes into contact with the skin is made of a nickel-free member. Therefore, if other metals that are sources of metal allergy are appropriately selected and prepared in combination with nickel that does not contain the metal of allergy source, users with various metal allergy constitutions can wear glasses according to their constitution. You can select the frame and use it with confidence.

[0023]

EFFECTS OF THE INVENTION The present invention has the above-described structure and action, and since the site that comes into contact with the skin is composed of a member that does not contain at least nickel, nickel does not come into contact with the skin, and nickel allergic Even people with this constitution can use it with peace of mind.
