By the way, the surface (e) of the vine (b) to which the butterfly piece (g) is attached is coated and protected. The pins (ri) and (ri) are made of metal, and the material is different from that of the resin vine (b), so the adhesion of the coating liquid applied is different, and the metal head surface (wa) Or, a situation occurs in which one of the coats on the vine surface (e) is peeled off. The appearance of the vine (b) is spoiled by the partial peeling of the coat.

Conventionally, various prior documents regarding the vines of resin eyeglass frames have been known.
For example, the "vine of the resin eyeglass frame" according to Japanese Patent Application Laid-Open No. 2000-310755 does not thicken the resin layer in order to counter the bending moment acting on the vine joint portion in the vine of the resin eyeglass frame. It is a highly elastic and strong vine.
That is, a core metal 1 is embedded in the central shaft of the resin vine, and the core metal 1 is a thin flat wire having a round wire having a circular cross section at the tip, and the thickness of the flat wire on the joint portion side of the core metal. Is slightly increased to cover the decrease in strength due to the softening phenomenon due to high heat when brazing the butterfly piece 2.
"Vine of resin eyeglass frame" according to JP-A-2000-310755

In a resin eyeglass frame, the head of a pin that fixes a hinge piece that can be attached so that the vine can be folded may spoil the appearance of the vine.
The problem to be solved by the present invention is this problem, and a vine joint structure of a resin spectacle frame capable of fixing a hinge piece constituting a hinge is provided so that the head does not surface. .. In addition to resin spectacle frames, spectacle frames made of tortoiseshell, spectacle frames using animal horns, or wooden spectacle frames are also included.

The spectacle frame according to the present invention is intended for resin, tortoiseshell, animal horns, or wooden spectacle frames, and the spectacle frame has a front portion and two vines, and the vines are front portions. It is attached to both sides of the eyeglasses so that it can be folded via hinges. The hinge consists of both wing pieces and a shaft pin (shaft screw), one wing piece is attached to the side end of the front part, the other wing piece is attached to the base of the vine, and both wing pieces mesh with each other. It is connected by a shaft pin in the state. Therefore, the vine can be folded by connecting it to the front part with a hinge.

Each butterfly piece is fixed by a pin press-fitted from the surface, and the tip of the pin penetrates a hole provided in the substrate of the butterfly piece and the tip is crimped. Then, the head of the pin is embedded in the surface of the front portion and the surface of the vine to form a recess. That is, a step is formed between the surface and the surface of the head to form a recessed state, and a disk-shaped piece made of resin, bekko, or wood is fitted in the recessed recess to be flush with the same surface. It is made up. The pin head is covered with the piece so as not to surface, and the entire surface is coated.

The vine joint structure of the resin spectacle frame, the bekko spectacle frame, the wooden spectacle frame, or the spectacle frame made of animal horns of the present invention is attached to both sides of the front part so that the vines can be folded through hinges. There is. The basic structure is the same as the joint structure that has been used conventionally, but the head of the pin that fixes the butterfly piece to the front part and the vine is embedded, and the recess formed is made of resin or bekko, etc. Piece is fitted.

That is, the pin head has a structure that does not surface to the outside, and the appearance is improved. There are hinges to which the vines are attached, but the hinge attachment structure is designed so that it does not surface.
The pin head is embedded in the surface to form a recess, and a resin piece, a bekko piece, or a wooden piece fits into the recess to form the same surface. Therefore, the coat formed by applying it to the resin surface or the surface of Becko or the like does not peel off and becomes a stable coat layer forever.

FIG. 5 is a cross-sectional view of an embodiment of the present invention in which a butterfly piece is attached to the inside of a vine. A specific example showing the appearance of a conventional resin eyeglass frame. FIG. 5 is a cross-sectional view of a hinge piece mounting structure constituting a conventional hinge, in which the butterfly piece is mounted inside a vine by two pins.

FIG. 1 is an example in which the hinge pieces constituting the hinge are fixed to the vine via a pin.
In the figure, 1 is a vine, 2 is one wing piece constituting a hinge, 3 is a substrate, 4a and 4b are pins, and the wing piece 2 is pinned by the substrate 3 in contact with the inner surface 5 of the vine 1. Has been done. The pins 4a and 4b have heads 6a and 6b having a large outer diameter, and the substrate 3 is arranged on the inner surface of the vine 1 and fixed by being sandwiched between the crimped portions 7a and 7b at the tip.
That is, the two pins 4a and 4b at predetermined intervals from the surface 8 of the vine 1 are press-fitted, the tip thereof is inserted through a hole provided in the substrate 3, and the portion protruding from the substrate 3 is crimped. 7a and 7b are formed.

The structure is the same as before, in which two pins 4a and 4b are press-fitted from the surface 8 of the vine 1, the tip protruding inward 5 is inserted into the hole of the substrate 3 of the butterfly piece 2, and the tip is crimped. is there. However, in the present invention, the heads 6a and 6b of the pins 4a and 4b are embedded in the vine 1, and a depression is formed on the surface 8. Then, resin pieces 9a and 9b or Becko pieces 9a and 9b are press-fitted to fill the dents.

Therefore, the surfaces 10a and 10b of the resin pieces 9a and 9b are flush with the vine surface 8, and of course, there is no step. If the resin pieces 9a and 9b are made of the same material as the vine 1, the mounting structure of the butterfly piece 2 is not surfaced, and not only the appearance of the vine 1 but also the appearance of the spectacle frame is improved.
Of course, it is also possible to give a kind of decorative effect by using the press-fitted pieces 9a and 9b. That is, the pieces 9a and 9b are made of a material different from that of the vine 1, and the surface 8 of the vine 1 can be decorated by press-fitting the pieces.

On the other hand, the pieces 9a and 9b can be press-fitted into the recess and the coating liquid can be applied to the surface 8 having the same surface to form a coating layer. Of course, it may not be coated, but the surface 8 of the vine 1 on which the heads 6a and 6b of the metal pins 4a and 4b are not surfaced has a stable coating layer and may be partially peeled off. The appearance of the vine 1 is not impaired. Of course, the same applies to the butterfly pieces attached to both sides of the front portion.

In the case of the front portion, two pins are press-fitted from the surface, and the butterfly pieces provided on the front portion are fixed by these pins. Then, the head is embedded inside the front portion to form a recess so that the head of the pin does not surface. Then, as in the case of the vine, a resin piece is press-fitted into the recess to close it. Therefore, the presence of the press-fitted pin is not surfaced, and the appearance of the front portion is improved.
