Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an eyeglass frame, and more particularly, to an eyeglass frame having a function as a health appliance.
[0002]
[Prior art]
Conventionally, in an eyeglass frame, it has been proposed that an ore that generates negative ions is contained in a member of the frame to achieve a health promotion effect by the generated negative ions. For example, in Japanese Patent Application Laid-Open No. 11-242190, in a spectacle frame including a plurality of parts made of metal or synthetic resin, at least a part of the surface of at least one part is formed with a coating film mixed with tourmaline ore. Are described. In Japanese Patent Application Laid-Open No. 11-271690, regarding a resin modern to be extrapolated to an ear hook of a temple of eyeglasses, tourmaline, an energy exchange material, and magnetite are provided on an elastic pad portion arranged at a portion facing the ear. It is described that a powder or molded article is included.
[0003]
On the other hand, natural radioactive rare element-containing minerals are known as negative ion generating substances. For example, JP-A-51-67089 describes that natural minerals containing radioactive elements such as radium, thorium, and uranium are powdered and mixed with building materials, walls, cement, synthetic resins, and the like. . Japanese Patent Application Laid-Open No. 2000-262641 describes an eyesight device that can be attached to a vine or the like of spectacles made of a material in which such a negative ion generating substance is uniformly dispersed in a synthetic resin material. .
[0004]
[Problems to be solved by the invention]
Although conventionally used tourmaline is listed as a negative ion generating substance, it is presently not clearly understood how negative ions are generated. In addition, as shown in JP-A-51-67089, generation of negative ions has been confirmed in natural radioactive rare element-containing minerals, but when mixed with synthetic resin, it becomes light pale brown. Since it is colored, its use as a surface material has a problem in design. It is also conceivable to attach another coloring material on top of that, but the amount of negative ions is reduced accordingly. In Japanese Patent Application Laid-Open No. 2000-262541, the design of the spectacle frame is used as it is by not using it directly for the spectacle frame but by mounting it separately from the frame. There are many design problems. In addition, since it is attached away from the human body, the generated negative ions react with the positive ions in the air before affecting the human body, and the effect is reduced.
[0005]
Therefore, an object of the present invention is to provide a spectacle frame that exhibits a sufficient negative ion effect using such a natural radioactive rare element-containing mineral and that does not limit the color of the spectacle frame.
[0006]
[Means for Solving the Problems]
An eyeglass frame according to the present invention is characterized in that a resin layer containing a powdered natural radioactive rare element-containing mineral is formed on at least a part of a surface of a member constituting the eyeglass frame on a human body side. Furthermore, the member is characterized in that a resin plate containing the mineral is bonded to another resin plate with an adhesive and is formed by machining. Furthermore, the member is characterized in that a laminated plate formed by extrusion using a plurality of types of resin materials including a resin material in which the mineral is mixed is formed by machining. Further, the resin layer is embedded in a concave portion formed in the member. Further, the resin layer is formed by being applied to the member.
[0007]
Since the present invention has the above-described configuration, the resin layer containing the natural radioactive rare element-containing mineral formed on the human body-side surface of the eyeglass frame is in close contact with the human body or is located at a close distance, which has occurred. Negative ions can have a sufficient effect on the human body, and have the effects of relaxing, relieving fatigue, promoting metabolism, promoting blood circulation, improving health, and improving physiological functions.
[0008]
And the outer part important in the design of the spectacle frame-that is, the surface of the constituent members of the spectacle frame on the side opposite to the human body can use the same coloring material as before, so that the design is not damaged. rare. Therefore, it is possible to realize a spectacle frame that can display various designs and can also expect a health promotion effect.
[0009]
Then, a powdered natural radioactive rare element-containing mineral is mixed to form a resin plate, which is then bonded to another resin plate constituting the outside of the eyeglass frame and molded by machining such as grinding to form a member. The resin layer containing the mineral can be easily formed. Further, by using a resin, it becomes possible to mold into various shapes as in the related art. If the laminated plate is formed by extrusion using the resin material mixed with the mineral and other resin materials, the resin layer containing the mineral can be easily manufactured with uniform quality.
[0010]
In addition, even after the members constituting the spectacle frame are formed, the resin layer can be easily formed by forming a concave portion in the member by machining or the like and embedding the resin containing the mineral therein. Even when the members constituting the spectacle frame are made of metal, the resin layer can be easily formed by applying and solidifying the liquid resin containing the mineral on the surface on the human body side. By forming the resin layer as described above, it is possible to form the resin layer without impairing the design of the finally finished spectacle frame.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of an eyeglass frame according to the present invention will be described in detail. FIG. 1 shows a perspective view of the entire eyeglass frame 1. A resin layer 2 containing a powdered natural radioactive rare element-containing mineral is formed inside the eyeglass frame 1 on the human body side, and another resin layer 3 is formed outside the eyeglass frame 1. . As shown in the plan view of FIG. 2, the entire rim frame and temple, which are members of the eyeglass frame 1, have a two-layer structure.
[0012]
FIG. 3 schematically shows a manufacturing process of the eyeglass frame 1. The resin plate 4 on which the resin layer 3 is formed is formed in a plate shape using a synthetic resin material such as acetate or celluloid. The resin plate 5 is obtained by mixing a powdered natural radioactive rare element-containing mineral with a synthetic resin material such as acetate or celluloid and solidifying it in a plate shape. It is preferable that the natural radioactive rare element-containing mineral is pulverized, fired, and powdered to have an average particle size of about 1 μm. Examples of the natural radioactive rare element-containing mineral include ores such as samarskiite (containing uranium oxide), fergusonite (containing yttrium oxide), and xenotime (containing yttrium oxide), but are not limited thereto. It is preferable that the amount of the mineral added is about 2% by weight at the stage of the resin plate 5. However, as long as the annual radiation dose is 1 mSv (milli-sievert) or less, there is no problem even if it is added more.
[0013]
The resin plates 4 and 5 thus formed are bonded to each other using an adhesive to form an integrated resin block 6. The resin block 6 is cut into an appropriate size and divided to form a large block 7 and a small block 8. Then, the large block 7 is formed into a rim frame 9 by machining such as grinding. Similarly, the small block 8 is formed into a temple 10 by machining such as grinding. Then, a hinge is embedded in both of them, and they are joined together with screws, so that the spectacle frame 11 is finished. The thickness of the resin layer 2 can be appropriately adjusted by the degree of grinding of the large block 7 and the small block 8. In addition, the resin layer 2 may be formed only on the temple 10, and the resin layer 2 may be left only on the ear hook portion of the temple 10 by grinding. In addition, the resin layer 2 may be left only at the nose pad portion of the rim frame 9, and where and how thick the resin layer 2 is formed can be set as appropriate.
[0014]
In the above example, the adhesive is manufactured using an adhesive, but it can be formed by extrusion. For example, as the material for forming the resin layer 2, a mixture of the powdered mineral described above and the chip-shaped resin material is used, and as the material for forming the resin layer 3, a coloring material such as a dye is added to the chip-shaped resin material. Using the mixture, the two are separately heated and melted, and then extruded at the same time to form a two-layer laminated plate of upper and lower layers. The laminated plate thus formed is processed into a rim frame or a temple by machining in the same manner as the resin block 6 described above. As described above, if extrusion molding is used, a uniform quality resin layer 2 can be easily formed, and a laminated plate having three or more layers can be easily manufactured. It is also possible to express deeper shades by being laminated.
[0015]
FIG. 4 shows an example in which a resin layer 13 containing a natural radioactive rare element-containing mineral is embedded in a temple 12. FIG. 4B is a cross-sectional view taken along line AA ′. The temple 12 has a groove 14 for embedding the resin layer 13 after being roughly formed from a resin block or a laminated plate by grinding or the like. As shown in FIG. 4B, the groove 14 is formed on the human body side, that is, on the inner surface when the temple is attached to the spectacle frame. The resin layer 13 is poured into the groove 14 after the powdered mineral is added to a liquid resin material appropriately selected from an acrylic resin, a urethane resin, an epoxy resin, a silicone resin, a polyester resin, and the like, and uniformly mixed. It is formed by solidification. After the resin layer 13 is formed, finishing of the entire temple 12 is performed. The resin layer 13 may be formed by solidifying a resin layer in advance into the shape of the groove 14, fitting the groove into the groove 14, and fixing the resin with an adhesive.
[0016]
FIG. 5 shows an example in which the resin layer 15 is applied and formed when the temple 12 is formed using a metal material. FIG. 5B is a cross-sectional view taken along line BB ′. Examples of the metal material used for the temple 12 include a titanium alloy, a nickel alloy, and nickel silver, and a resin material that adheres to such a metal material is preferably used for the resin layer 15. For example, the above-mentioned powdered mineral is added to a liquid resin material appropriately selected from an acrylic resin, a urethane resin, an epoxy resin, a silicone resin, a polyester resin, and the like, and uniformly mixed. Thereafter, as shown in FIG. 5B, a resin layer 15 is applied to a predetermined thickness on the side of the human body when the temple 12 is attached to the spectacle frame, that is, on the inner surface. By using the above method, a resin layer containing a natural radioactive rare element-containing mineral can be formed even in an eyeglass frame formed of a metal material. Of course, such a coating method can also be adopted for a spectacle frame formed of a resin material.
[0017]

[0018]
And the outer part important in the design of the spectacle frame-that is, the surface of the constituent members of the spectacle frame on the side opposite to the human body can use the same coloring material as before, so that the design is not damaged. rare. Therefore, it is possible to realize a spectacle frame that can display various designs and can also expect a health promotion effect.
[0019]
Then, a powdered natural radioactive rare element-containing mineral is mixed to form a resin plate, which is then bonded to another resin plate constituting the outside of the eyeglass frame and molded by machining such as grinding to form a member. The resin layer containing the mineral can be easily formed. Further, by using a resin, it becomes possible to mold into various shapes as in the related art. If the laminated plate is formed by extrusion using the resin material mixed with the mineral and other resin materials, the resin layer containing the mineral can be easily manufactured with uniform quality.
[0020]
In addition, even after the members constituting the spectacle frame are formed, the resin layer can be easily formed by forming a concave portion in the member by machining or the like and embedding the resin containing the mineral therein. Even when the members constituting the spectacle frame are made of metal, the resin layer can be easily formed by applying and solidifying the liquid resin containing the mineral on the surface on the human body side. By forming the resin layer as described above, it is possible to form the resin layer without impairing the design of the finally finished spectacle frame.
