Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure for attaching a decorative part to be attached to a spectacle frame vine provided with a spring hinge.

[0002]

[Prior art]

 General eyeglass frame vines are foldably connected via hinges. The armor is brazed to the frame that holds the lens, and each hinge piece of the hinge is brazed to the inner surface of the end of the armor and the vine, which means that the horn bends against the fixed armor. However, the vine cannot sustain a stable folding operation. In other words, a small hinge may loosen its shaft screw or wear on the sliding surface, resulting in looseness of the vine, and the worn glasses may be displaced or come off.

In addition, since the hinge is small in size, it is troublesome to manufacture, and the hinges in the most open state are parallel to each other, and the joint structure does not open further. Of course, if the eyeglasses are simply worn on the face, the opening degree of the vine is sufficient, and since the vine has some elasticity, it can be slightly curved to fit on the face. .

However, it is only for a short period of time that the spectacles worn by the vine do not rattle because they fit the face only with the spring characteristics of the vine, and the spring characteristics of the vine itself are extremely bent and plastically deformed. Unless the material is used, it is always constant and can be restored to its original shape by removing the force, but as mentioned above, the hinge connecting the vines becomes loose. In the conventional hinge joint structure using only hinges, there is no means to absorb the impact force when some kind of impact is applied to the front frame, and the glasses may fall from the face, the lens may be damaged, There are also situations where the frame itself is bent.

By the way, as one means for solving such a problem of the spectacle frame, a joint structure that allows the temple to be opened slightly further outward from the linear state with the armature is desired and used partially. ing. FIG. 7 shows a conventional example of this joint structure, which is called a spring hinge. That is, the basic idea of the spring hinge is to braze the fixed butterfly piece (b) to the armor (a) and fix the other hinge piece as a sliding butterfly piece (c) to allow sliding for a certain distance. , The outward opening can be given to the crane.

A guide groove (e) is formed inside the temple (d), and the sliding butterfly piece (c) slides using the guide groove (e) as a guide. A coil spring (F) is housed inside the moving butterfly (C). Therefore, when the crane (d) is opened to the outside, the contact point (g) between the armor (a) and the crane (d) serves as the base point, and the sliding butterfly piece (c) is pulled toward the fixed butterfly piece (b) side. Then, the coil spring (f) is compressed. A clasp (H) is housed in the sliding butterfly (C), and the claw (L) is locked to the bottom of the guide groove (E) of the temple (D), and the coil spring (F) is It is interposed in a compressed state between the metal fitting (h) and the groove bottom (n) of the sliding butterfly (c).

Therefore, by pushing the crane (d) outward, the sliding butterfly (c) moves to the fixed butterfly (b) side, the coil spring (f) is compressed, and the coil spring (f) is restored. The vine (d) pushed open by the action of force tries to return to its original position. If the spring force is applied to the temple (d) in this way, the rattling of the temple (d) is prevented, and the worn glasses do not cause a stable position shift.

By the way, since the spectacle frame itself has a decorative function, it is provided with various decorations. One of them is that metal pieces are attached to the outer surface of the vine. This kind of metal piece is fixed by inserting a screw pin provided on the back side into a hole penetrating the vine and screwing a nut on the inside of the vine to fix it, or by caulking the part protruding to the inside. . However, a spring hinge type crane as shown in FIG. 7 cannot be provided with a hole through which the screw pin is inserted.

[0009]

[Problems to be solved by the present invention]

 As described above, it is not possible to attach a decorative part made of metal pieces or the like to the outer surface of the temple of the eyeglass frame provided with the spring hinge. The problem to be solved by the present invention is this problem. It is possible to attach a metal piece or the like even to a crane that is connected by a spring hinge, and there is no hindrance to the function of the spring hinge. The attachment structure for decorative parts is provided.

[0010]

[Means for Solving the Problems]

 The structure for attaching the decorative part to the spring hinge vine of the spectacle frame according to the present invention is configured so that the function of the spring hinge is not hindered when the decorative part is attached to the outer surface of the vine. Although the basic structure is almost the same as that shown in FIG. 7, a guide groove is formed inside the temple for the sliding butterfly piece to be constrained to move, and a pin hole penetrates through this guide groove. A groove is formed around the pin hole.

A pin projects from the back surface of the decorative component, the pin is inserted into a pin hole formed by penetrating the temple, and the pin tip is crimped. The caulking portion is fitted in the groove formed around the pin hole, and the caulking secures the decorative component, and the caulking portion does not protrude from the bottom of the guide surface. Therefore, there is no hindrance to the movement of the sliding butterfly piece. Further, when fixing the decorative component with a single pin, the decorative component rotates around the pin, but is provided with a detent.

As the rotation preventing means, two pins may be provided on the above decorative component. When fixing with one pin, the back surface of the decorative component and the temple surface are fitted to each other to prevent rotation. It can also be configured to. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.
