Abstract

<P>PROBLEM TO BE SOLVED: To provide light and fine resin frame components decorated in such a manner that enlarged portions and non-enlarged portions appear in relief. <P>SOLUTION: The spectacle frame components 10 composed of transparent thermoplastic resins partially or wholly having convex curved surfaces on the surfaces are used as base materials and after the rear faces 13 of the spectacle components are coated with a primer 14, gold foil 15 is scattered and sprinkled on the back surfaces and thereafter the rear faces of the spectacle frame components are subjected to coating with a pearl coating material 16 of the color different from that of the sprinkled gold foil so as to cover the gold foil to provide the decorations in such a manner that the portions decorated with the gold foil apear to vary in the enlarged portions and non-enlarged portions depending upon angles owing to the convex lens effect of the convex curved surfaces and appear in relief at some angles. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention particularly relates to a decorative spectacle frame component made of resin.

  The main methods for decorating conventional resin frames are: (a) a decorative object brazed to a temple core and covered with a transparent resin so that it can be seen from the outside; (b) the outside However, a transparent resin plate and a colored resin plate on the inner side were laminated to form a double structure, and a color difference was provided.

  However, as shown in (a) above, a decorative object is brazed to a temple core, covered with a transparent resin and seen through from the outside, the frame itself becomes thicker and heavier, and the nose, ears The skin will rub and become red due to the burden on the skin. The decoration can only be applied to limited parts. Next, as shown in (b), the outer plate is transparent and the inner colored plate is laminated to form a double structure. In addition, it must be decorated by cutting or the like, which is very laborious and expensive. Also, it was very difficult to give decorations that looked up.

  Accordingly, in the present invention, a spectacle frame component made of a transparent thermoplastic resin having a partially or entirely convex curved surface is used as a base material, and after applying a primer to the back surface of the spectacle frame component, a metal The foil is scattered on the back surface, and then the back surface of the spectacle frame part is coated with a paint having a color different from that of the sown metal foil so as to cover the metal foil, The above-mentioned problem has been solved by making the enlarged portion and the non-enlarged portion appear to change according to the angle by the convex lens effect of the convex curved surface, or to appear to rise depending on the angle.

  The decorative spectacle frame part of the present invention can use light and thin members as they are without making temples and other frame parts thick, large and heavy, and in appearance, that is, when viewed from the eyes of others. By changing the viewing angle or the angle of exposure to light, the decorative part of the frame part to which the decoration of the present invention is applied changes the enlarged part and the non-enlarged part due to the convex lens effect of the convex curved surface of the frame part surface. It is possible to easily and inexpensively provide spectacle frame parts and spectacles that appear and appear to rise depending on the angle and have a decorative effect that has never been seen before.

  In a spectacle frame part made of a transparent thermoplastic resin having a partially or entirely convex curved surface, after applying a primer on the back surface of the spectacle part, the gold foil is scattered on the back surface, The back surface of the spectacle frame component is coated with a pearl paint having a color different from that of the plated gold foil so as to cover the gold foil, and the gold foil decoration portion is enlarged and non-expanded due to the convex lens effect of the convex curved surface. The decoration was realized so that the image appears to change depending on the angle, or the image appears to rise depending on the angle.

  Hereinafter, the present invention will be described in detail with reference to the drawings. (Hereinafter, a description will be given with a temple as a representative of a spectacle frame part.) FIG. 1 is a perspective view of a temple 10 decorated with an embodiment of the present invention. The temple 10 that does not have a reinforcing cored bar is made of a transparent thermoplastic resin whose surface 11 has a partially or entirely convex curved surface 12. The transparent thermoplastic resin includes one selected from polyamide, polyimide, polyetherimide, polycarbonate, polysulfide polymer, polysulfone, polyetherketone, and other engineering plastics, and / or a blend or alloy thereof. Is preferred.

  FIG. 2 is an enlarged cross-sectional view taken along the line B-B of FIG. 1. The surface 11 of the temple 10 is formed as a convex curved surface 12 and the center is not reinforced with a cored bar. Can be seen. And the primer 14 is apply | coated to the said back surface 13 (a primer may be apply | coated entirely). Next, the metal foil 15 (preferably a gold foil) is spread and scattered, and the entire back surface or a part of the metal foil 15 is applied so as to cover the metal foil with a paint 16 having a color different from that of the metal foil. . Of course, it does not matter if the painted portion is applied to the upper surface 17 and the lower surface 18 of the temple.

  The paint 16 is preferably a pearl paint, and if a pearl paint that is thin enough to transmit light is used, the effect of making the decorative part stand out vividly and float is increased. Moreover, you may give a clear coat in the whole.

  FIG. 3 is a cross-sectional view of the temple 10a in the enlarged cross-sectional view taken along the line B-B in FIG. 1, and a part of the temple 10a may be convex in this way. In the portion 15a, a portion that appears to be enlarged and a non-enlarged portion appear due to a change in angle, and appear to float depending on the angle.

  Further, the cross-sectional shape may be elliptical as shown in FIGS. Moreover, the cross-sectional shape of a part of the temple may be the convex curved surface or the spherical surface. And the decoration part may be given on a plane like FIG. 3, and may be given on a curved surface like FIG.

  FIG. 6 is a cross-sectional view for explanation when gold foil is used for the decorative part and pearl paint is used for the paint. In this case, the gold foil 15 which is the decorative part is clearly visible. The multilayer structure of 16 plate-like particles 21 repeats regular reflection / transmission to cause multi-layer reflection, pearly luster occurs, and a part of the multi-reflected light passes through the gold foil. It is assumed that the gold leaf 15 is conspicuously seen as receiving the backlight due to the bright golden reflection 22 on the surface of the gold leaf.

  FIG. 7 is a view of the temple decoration portion viewed from the position of the arrow C in FIGS. Further, when viewed from the angle of the arrow F, there is an effect that the virtual image of the decorative portion reflected on the upper surface or the lower surface remains and floats up. Such an effect cannot be obtained with a conventional resin temple penetrating a metal core. In spite of these effects, the temples are much lighter and thinner than before. Therefore, the burden on the ear or nose of the wearer and the body is reduced.
