Description

Hinge manufacturing method and that hinge of metal eye-glasses

The present invention relates to a hinge manufacturing method of the metal glasses and the hinge, and more specifically, to form a hinge to connect the eyeglass legs from the eyeglass frame integrally to the eyeglass frame and the eyeglass legs to be mutually assembled and assembled In addition to the convenience of the glasses production cost is to be significantly reduced.

In general, metal glasses have a structure that connects eyeglass legs to both ends of the frame, and then obtains an integrated eyeglass frame by blanking the metal plate (using a mold to obtain a specific shape from the metal plate). After the bending process is made of a spectacle frame is made of a structure that connects the spectacles legs on both sides end, the object to be carried out in the present invention is a spectacle frame obtained by integrally by blanking the metal plate.

Therefore, the following background description will be limited to the one-piece glasses using the metal plate.

Metal glasses (hereinafter referred to as 'glasses') generally have a structure in which a pair of spectacle frames for installing a lens and a pair of spectacles for wearing glasses are coupled to each other by a hinge. After forming the connecting rod bent in the form of "a" by welding or adhesive method, the hinge of the pair of glasses is mutually coupled by a screw by providing a hinge of the spectacle frame at one end of the connecting rod.

Here, the spectacle hinge is configured by arranging a pair of fixing pieces having a coupling hole formed at regular intervals up and down, and at the same time, forming a screw with a coupling hole of the fixing piece on one side thereof.

The hinge of the spectacles is made of a joining piece having a coupling hole and is constructed by welding or bonding to one side end of the spectacles.

As described above, the conventional eyeglass hinge is a structure in which the hinge frame and the eyeglass legs are separately configured and then assembled together, and the construction and assembly thereof are very difficult, and the configuration process is complicated, resulting in a large amount of defect rate as well. It was a situation that caused an increase in manufacturing costs.

In order to describe this in more detail, a conventional eyeglass hinge manufacturing method will be described.

Attaching step of attaching the connecting rod bent in the form of "b" with a welding or adhesive to the both ends of the eyeglass frame formed integrally with the lens mounting portion and the nose ring mounting hole through the blacking process;

A pair of eyeglass frame hinges configured to attach a pair of fixing pieces having a coupling hole to one side end of the connecting rod with a welding or adhesive at a predetermined interval up and down, and to form a screw with a coupling hole of the one fixing piece;

An eyeglass hinge hinge step of attaching a coupling piece having a coupling hole to one end of the eyeglass by welding or adhesive;

The hinge coupling step of placing the coupling pieces of the eyeglass hinge hinge between the upper and lower fixing pieces of the eyeglass frame hinge to screw each other.

Therefore, such a conventional eyeglass hinge is manufactured by separately manufacturing the eyeglass frame and the hinge and the eyeglass leg and the hinge through a separate process, and then attached and assembled by the above method, the process and assembly is very difficult. In addition, there is a problem that a lot of defects occur when the hinge is attached by welding or adhesive, which makes it impossible to reduce the work efficiency and mass production, and also has a problem of raising the cost of the product according to the individual manufacture of the hinge.

The present invention has been invented to solve the above-mentioned conventional problems, in particular, by presenting a hinge manufacturing method of integrally constituting the hinge to each side of the spectacle frame both ends and one end of the glasses leg to simplify the manufacturing process and parts of the hinge In addition, the invention has been invented with a focus on the technical problem in order to maximize productivity as well as reduce manufacturing costs.

In order to solve the above problems, the hinge manufacturing method of the metal glasses proposed in the present invention,

A metal frame member is manufactured by blinding the lens frame 101 and the nose frame mounting hole 102 to produce a spectacle frame 100, with both ends of the spectacle frame 100, the upper and lower fixing pieces 12, 12 '.
