The present invention relates to a hinge fixing structure of a synthetic resin spectacle frame, and more particularly, a hinge for connecting the spectacle leg so that it can be folded to the eyeglass frame more quickly and conveniently, as well as a beautiful appearance and a hinge at a precise position. It relates to a hinged structure of a synthetic resin frame (including glasses legs) configured for installation.

In general, synthetic eyeglass frames are manufactured by injection molding, unlike metal eyeglass frames, so they can be mass-produced and inexpensively supplied for practical use.

In the conventional configuration of forming a hinge for connecting the eyeglass frame to the synthetic resin eyeglass frame as described above, there is one configured to install the eyeglass leg by injecting the shape and shape of the hinge integrally when the synthetic eyeglass frame is ejected from the mold, the hinge in this configuration It is not precise, and the structure of the injection mold is complicated, so there are other disadvantages such as high cost.

In order to solve these shortcomings, the synthetic eyeglass frames are injected, and a metal hinge is provided and installed separately.

In this case, after the metal hinge was heated, the hinge installation part of the synthetic resin eyeglass frame was melted using the heat so that the metal hinge was fixed to the synthetic eyeglass frame.

In the case of doing as described above, the work time due to heating and pressurizing the hinge takes a lot, and thus the productivity is lowered.

In addition, the accuracy is reduced, when the installation of the spectacles on the spectacle frame is twisted because the spectacles are installed in relation to the reliability in terms of quality is deteriorated in the end is a major obstacle to the high-grade synthetic resin spectacle frame, there is a problem such as a competitive advantage.

The hinge fixing structure of the synthetic resin spectacle frame of the present invention for solving the above problems can be easily assembled by forming a hinge for connecting the eyeglasses legs to the synthetic resin spectacle frame to install the hinge on the spectacle frame more quickly and conveniently The purpose is to reduce the cost by improving the productivity, and to make the appearance beautiful, and in particular, by installing the hinge at the correct position on the spectacle frame to increase the reliability of the quality of the synthetic resin spectacle frame to have a competitive edge.

The hinge fixing structure of the synthetic resin spectacle frame of the present invention for achieving the above object is provided with a fixing hole formed with a screw hole to form a seating groove and a screw groove for coupling the hinge to the hinge mounting portion for connecting both sides of the spectacle frame It is characterized in that by providing a hinge coupled to the fixing portion of the hinge to the seating groove and screwed through the screw groove, described in detail with reference to the accompanying drawings as follows.

1 is a perspective view showing the overall configuration of the present invention, Figure 2 is an exploded perspective view of the main portion of the present invention, Figure 3 is an enlarged cross-sectional view of the main portion of Figure 1 according to the present invention, Figure 4 is an enlarged other configuration of the present invention One cross section.

In forming the synthetic resin eyeglass frame of the present invention, to form a mounting groove (2) for coupling and fixing the hinge (1) to the hinge installation portion (4) for connecting the eyeglass legs on both sides of the eyeglass frame (5), The screw groove 3 is formed to penetrate from the side or the bottom of the groove 2 to the mounting groove 2,

The hinge 1 is formed on the eyeglass frame 5 by forming a fixing part 100 having a screw hole 10 to be coupled to the seating groove 2 and coupled to the screw 6 coupled through the screw groove 3. Combining the fixing portion 100 of the hinge (1) to the seating groove (2) formed, is configured by coupling the screw (6) to the screw groove (3) and the screw hole (10),

The seating groove 2 and the fixing part 100 of the hinge coupled thereto are formed to have a square or one or more planes in cross section so as not to turn in a coupled state,

In the seating groove 2 and the hinge 1, a step groove 20 is formed around the inlet of the seating groove 2 in order to prevent the hinge from moving in the correct position, and the fixing part 100 of the hinge 1 is fixed. It is configured to form the engaging piece 200 to be coupled to the end groove 20 at the starting point.

In the drawings, reference numeral 30 denotes a nose support of the glasses, 31 a lens, and 32 a glasses leg.

Referring to the operation of the hinge structure of the synthetic resin eyeglass frame of the present invention as described above in detail as follows.

First, the mounting groove 2 for coupling and fixing the hinge 1 to the hinge installation portion 4 for connecting the glasses legs to both sides of the eyeglass frame 5 is formed, and the fixing portion formed in the hinge 1 ( Since the screw 6 is coupled to the screw groove 3 and the screw hole 10 to fix the screw hole 3 formed through the screw hole 3 in the fixing part 100. 10 is fastened to the hinge 1 is fixed to the hinge installation portion (4).

Therefore, the hinge 1 may be firmly coupled to the hinge installation unit 4 unless the screw 6 fastened to the screw hole 10 is disassembled.

In addition, a square or one or more cross-sections of the seating grooves 2 formed in the hinge installation part 4 of the eyeglass frame 5 and the fixing part 100 of the hinge are flat and formed at the entrance of the seating groove 2 ( 20) and the locking piece 200 formed in the hinge can be fixed in the correct position without the hinge is coupled to the seating groove is not deeply entered into the seating groove.

The hinge (1) made of metal on the spectacle frame (5) formed of synthetic resin is fixed to a rigid and accurate position and can be used to interconnect with the hinge formed on the spectacles. When using the spectacles, the hinge mounting part is used to fold and unfold the spectacles. Pulling phenomenon received from the hinge (1) installed in (4) is eliminated by the screw (6) and the engaging piece 200, so it can withstand the movement that occurs when folding and spreading the glasses legs can maintain a firm coupling state.

According to the hinged structure of the synthetic resin eyeglass frame (including glasses leg) according to the present invention as described above, since the metal hinge can be easily and firmly fixed to the synthetic eyeglass frame, the productivity is improved and the cost is reduced. The appearance is beautiful, and in particular, the hinge is installed at the correct position on the spectacle frame, thereby increasing the confidence in the quality of the synthetic resin spectacle frame and having an effect such as competitiveness.
