Description

[Detailed explanation of the invention] The vertical piece of the cross-shaped connecting fitting, which is called a armor in the industry and is generally attached to the joint part of the lens frame by brazing, is connected to the temple with a hinge. Therefore, each time the temples are opened or closed, a bending force is applied to the square-shaped metal fittings, which causes them to open outward, widening the distance between the ends of the temples, making the ear hooks at the ends of the temples no longer close to the face, and making it difficult to wear glasses. It will slide down, and you won't feel stable when wearing it.

The purpose of the present invention is to provide armor, that is, a connecting metal fitting, that will not cause the armor to bend outward from the bending part and widen the distance between the ends of the temples due to opening and closing of the temples, even if the glasses are used for a long time. That is.

The present invention uses vertical pieces 2 of the 〓-shaped connecting fittings, which are called in the industry as armor that is brazed to the joints of the metal frame of the lens, or the 〓-shaped connecting fittings that are fixed to both left and right sides of the upper edge of the plastic frame. In the case of a plastic frame, fold the joint 3 inward so as to surround it with the horizontal piece 1, or in the case of a plastic frame, bend it inward so that the protruding part of the upper edge to which the horizontal piece 1 is fixed is surrounded by the horizontal piece 1, and then A gap 5 is provided between the folded piece 4 which is bent inward and the folded piece 6 is bent outward, and this bent piece 6 is bent in the same direction as the square-shaped vertical piece 2, that is, vertically. This invention relates to a metal fitting for connecting an eyeglass frame and a temple, in which a hinge is formed on the inner surface of No. 7 as a brazing surface.

When wearing glasses, the left and right temples are generally opened to the larger eyes. When pushing in, the ear hook part at the end of the temple 8, that is, the modern 9, has a downward bent part bent inwardly, so the temple is expanded at the lower end of the downward bent part of the modern. Pushed in. At this time, in conventional eyeglasses, a bending force acts on the bending part of the armor 10, that is, the 〓-shaped connecting metal fitting, and it gradually opens outward, widening the distance between the left and right ends 9, making it difficult to wear the glasses. It has a stick and is easy to slide down.
In order to see clearly, I have to push my glasses in and raise the lens position all the time. Also, when opening the temple, the joint tends to be turned inside out, and the groove line soldered to joint 3 is likely to be turned over, which may cause the edge of the lens to chip or cracks to form in the lens.

However, according to the present invention, the force that prevents the ear hook portions of the vines from spreading from side to side is applied to the bending portion between the inwardly bent bending piece 4 of the connecting fitting and the opposing bending piece 6. This force acts as a force, and since this force does not reach the horizontal piece 1 of the joint 3, the groove line soldered to the joint 3 will be reversed, resulting in chipped edges of the lens or cracks in the lens. There's no way I can get in. In addition, the size of the bending of this bent part is such that the gap 5 between the inwardly bent bent piece 4 and the opposing bent piece 6 is as small as a gap, so that no permanent deformation occurs, and due to its elasticity. It has excellent effects such as being easily restored and allowing the mod to be used in close contact with the sides of the face.

Claims (1)

[Scope of utility model registration request] The vertical piece 2 of the 〓-shaped connecting piece that connects the eyeglass frame and the temple is bent inwardly with the horizontal piece 1 so as to surround the joint 3 of the lens frame, and this is further bent inwardly to form a bent piece 4. Bend this bent piece 6 outward with a gap 5 between it and bend it in the same direction as the square-shaped vertical piece 2, that is, vertically, and place the inner surface of this bent piece 7 on the brazing surface of the hinge. A metal fitting for connecting the formed glasses frame and temple.
