Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an eyeglass frame in which precious metal parts such as gold and platinum are attached for decoration.

[0002]

[Prior art]

 The eyeglass frame can be hung on the face by fitting the lens to the rim formed on the front part. Therefore, the eyeglass frame needs to be light and hard to get tired, and a recent metal eyeglass frame is often made of a light material having excellent spring properties such as titanium. On the other hand, eyeglasses are required to be fashionable because they are worn on the face, and are decorated not only with functionality but also with various decorations.

For example, the eyeglass frame is often decorated by plating, painting, or printing, but other decorative parts can be attached. For example, jewelry such as diamonds and rubies are fixed to the base, and this is attached to the vine or the front part of the glasses frame. In many cases, decorative parts made of base metal such as gold or platinum are attached. FIG. 5 shows a part of the eyeglass frame. A roy (b) is attached to the outside of the rim (a), and a vine (d) is attached to the tip of the roy via a shaft coupling (c). They are connected so that they can be folded.

A groove is provided on the outer surface of the vine (d), and a noble metal component (e) is fixed to the groove. Two pins (f) and (f) protrude from the back side of the noble metal part (e), and these pins (f) and (f) pass through holes provided in the vine (d), and The tip is crimped. By the way, the wire rods of the components that make up the eyeglass frame in recent years are very thin. For example, a groove is provided on a vine (d) having a height of about 2 mm, a precious metal component (e) is fitted, and In (f), caulking is often difficult in terms of space. In this case, the tip of the crimped pin is exposed on the back side of the vine (d), which is not preferable in appearance.

On the other hand, in the case of a spectacle frame made of titanium, since the above-mentioned noble metal parts cannot be directly brazed, nickel plating must be applied to titanium in advance. appear. Corrosion also causes cracks in the corners, leaving problems in strength. When brazing, extra brazing often flows to the surface and the appearance of the eyeglass frame is often impaired.

[0006]

[Problems to be solved by the invention]

 As described above, there is a problem as described above when attaching a conventional decorative component made of a noble metal. The problem to be solved by the present invention is this problem. Even if it is a very thin and slim eyeglass frame, it provides an eyeglass frame in which small noble metal parts are stably mounted.

[0007]

[Means for solving the problem]

 The eyeglass frame according to the present invention has noble metals such as gold and platinum attached as decorative parts. In recent years, eyeglass frames are made of very thin wires, preferably made of a material such as titanium, which is light and has excellent spring properties. In the present invention, the precious metal decorative parts are stably mounted on the slim eyeglass frame made of such a thin wire, but spot welding is used as the mounting means.

A small projection is provided on the back side of the noble metal decorative component, and spot welding is performed via the projection. The projection may be very thin and short, and can be stably attached even if the base of the attached frame is small. Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0009]

【Example】

 FIG. 1 is an embodiment showing an eyeglass frame according to the present invention. The appearance is almost the same as that of the eyeglass frame shown in FIG. 5, but the form of the precious metal part 2 attached to the vine 1 is different. ing. That is, the noble metal component 2 is a wire having an elongated rectangular cross section, and is attached to the surface-side corner of the crane 1. That is, a notch groove is formed in the surface side corner of the crane 1, and the noble metal parts 2 and 2 are fitted and attached to this groove. If the height dimension H of the crane 1 is 2 mm, the noble metal part 2 becomes a square bar of about 0.7 mm.

In the present invention, spot welding is adopted so that the noble metal component 2 can be attached to the vine 1 even if it is so thin. In addition, a small projection is provided on the back side of the noble metal component 2 in order to limit the welding location, and spot welding is instantaneously performed via the projection.

FIG. 2 shows a specific example of the noble metal component 2, and a projection 4 is provided on the back surface 3 so as to protrude. The projection 4 is an elongated projection having a triangular cross section, and the tip is pointed. Here, even if the material of the crane 1 is titanium, spot welding is performed via the projections 4 without applying nickel plating to the surface. Since the projection 4 is small and the pointed end is sharp, welding is performed instantaneously.

At this time, if spot welding is performed in an inert gas atmosphere, the welding strength is further increased. Here, the shape of the projection 4 is not particularly limited, and a conical projection with a sharp tip may be provided at two places on both ends of the back surface 3 of the noble metal component 2.

FIG. 3 shows another embodiment of the glasses frame according to the present invention, in which a curved noble metal part 5 is attached to a vine 6. The noble metal component 6 is fixed to the crane 6 at both front and rear ends thereof, and the above-mentioned projections are provided at both ends thereof. FIG. 4 is an enlarged view showing the noble metal component 5, and conical projections 7a and 7b are provided on the back surfaces at both ends. Both ends of the curved noble metal part 5 are fixed while leaving a gap between the noble metal part 5 and the crane 6. Moreover, since the welding is performed by spot welding, the attachment strength is high, and the noble metal component 5 does not come off the crane 6.

The projections 7a and 7b are spot-welded by instantaneously applying a high current in a state where the projections 7a and 7b are in contact with the pedestal of the crane 6. , Fats and oils, and oxide film are removed. As described above, the megane frame according to the present invention is obtained by spot welding noble metal parts, and has the following effects.

[0015]

[Effect of the invention]

 The eyeglass frame of the present invention has a noble metal part attached for decoration, and the noble metal part is spot-welded to the frame. At this time, a small projection is provided on the back surface of the noble metal part, and spot welding is performed through the projection, so that even narrow and small noble metal parts can be spot-welded, and mounting is stable. I do.

[0016] Even if the eyeglass frame is made of titanium, spot welding is possible, and there is no need to previously apply nickel plating as in the conventional brazing, there is no allergy problem, and the brazing at the time of brazing is not performed. It does not damage the appearance of the frame.
