Description

[Detailed Description of the Invention] The present invention relates to plastic eyeglasses that simplify the installation of hinges on the plastic eyeglasses and also allow the use of hinges with decorative patterns on their surfaces.

Conventionally, in plastic eyeglasses, grooves were formed on both sides of the frame body into which hinges (commonly known as "armor hinges") for connecting the glasses were to be embedded.
After the hinge is brazed into the groove, the hinge is plated, but since the plating process requires a temperature of around 140 degrees, chemicals are required in the pre-treatment stage of the plating process. The material itself of the plastic eyeglass frames is attacked, reducing the product value.In addition, the hinges that are used are not attacked by chemicals during the plating process, so the plating process is also done with gold plating. It has been impossible to use hinges with decorative surface patterns, etc., which are difficult to pre-treat.

In view of these drawbacks, the present invention provides a plastic eyeglass frame in which grooves are cut out on both sides of the plastic eyeglass frame to embed and attach hinges that connect the tips at the ends. The above-mentioned drawbacks are solved by providing plastic eyeglasses in which the hinges are fixed with screws through holes drilled from the back side of the eyeglass frames after the hinges are embedded in the grooves and fitted with screws. An embodiment of the present invention will be described below based on the drawings. 1 is an eyeglass frame made of plastic;
A groove 4 into which a hinge 3 to which a wisdom piece 2 is connected is embedded is formed in the end portions of both sides of the eyeglass frame 1.

As shown in FIG. 2, the groove 4 is formed at both side ends of the eyeglass frame body 1, and when the upper and lower rod members 5, 5a remain and the hinge 3 is embedded, the surface portion 6 of the hinge 3 is inserted into the eyeglass frame body. The side end 7 of the hinge 3 is shaped to be flush with the back surface of the eyeglass frame 1.

The hinge 3 according to the present invention has been plated with an aesthetic decorative pattern on the surface in advance, and after being embedded in the groove 4 of the eyeglass frame 1, the hinge 3 is inserted through the through hole 8 drilled from the back side of the eyeglass frame 1. By forcibly inserting the screw 9, the screw 9 is screwed into the back surface 10 of the hinge 3, and the hinge 3 is integrated with the eyeglass frame 1.

Incidentally, a screw hole may be provided in advance in the back surface portion 10 of the hinge 3 so that the screw 9 can be easily screwed into the hole.

Reference numerals 11 and 11a are branch pieces that protrude above and below the side end 7 of the hinge 3, and holes 12 and 12a to which the chisel 2 is connected are formed in the branch pieces 11 and 11a.

In short, the present invention consists of a plastic eyeglass frame 1
A plastic eyeglass frame has a groove 4 cut out on both sides of the frame to which a hinge 3 for connecting the tooth 2 is embedded and installed, and the hinge 3 is plated with a surface decoration pattern etc. After the hinge 3 is fitted into the groove 4, the hinge 3 is screwed through the through hole 8 drilled from the back side of the eyeglass frame 1, so the conventional method of brazing the hinge 3 is completely eliminated. Since the hinge 3 can be screwed through the through hole 8 drilled from the back side of the eyeglass frame 1 without using the plastic eyeglass frame 1, plastic eyeglasses can be made with the chemicals necessary for plating in the pre-treatment step. There is no fear that the frame material itself will be attacked, and therefore the hinge 3 can be decorated with all kinds of aesthetic decorative patterns depending on the time and place, which significantly increases the commercial value. It is possible to improve.

Furthermore, in the case of the present invention, since the hinge 3 is securely screwed into the eyeglass frame body 1 with the screw 9 in an embedded state, there is no fear that the hinge 3 will wobble once it is screwed on, and it can be used permanently. In addition, compared to the method of protruding a pipe body from the hinge 3 and embedding the pipe body in the eyeglass frame body 1, the productivity is extremely high because precision in the installation and angle of the pipe body is not required. high,
Since the hinge 3 is thick, it can sufficiently play the role of a pipe body, and since the hinge 3 can be easily replaced, it has great practical effects, such as being able to provide functional eyeglasses.
