In addition, the top surface of the upper hinge shaft 141 and the bottom surface of the lower hinge shaft 141 are the inner top surface of the upper insertion groove 133 of the temple connection portion 113 and the inner lower surface of the lower insertion groove 133. It is formed with a corresponding inclined surface, and at this time, the thickness (T) between the rear end of the upper hinge axis 141 and the rear end of the lower hinge axis 141 is the inner tip and lower insertion of the upper insertion groove 133 of the temple connecting portion 113. It is set larger than the width (S) between the inner ends of the grooves (133).

Figures 4a to 4d are plan views showing the main parts of the temple assembly process and folding process of the temple hinge connection device for an eyeglass frame according to the present invention.

The temple hinge connection device 100 for an eyeglass frame according to the present invention not only allows the temple 120 to be easily assembled to the main front 110, but also allows the temple 120 to rotate stably without fear of separation, and the temple (120) is able to maintain a stable folded and unfolded state. The temple assembly process and temple folding operation process are described below.

First, when assembling the temple 120 to the main front 110, the main part of the temple 120 is located behind the insertion groove 133 of the temple connection part 113 of the main front 110, as shown in FIGS. 2, 3a, and 4a. The hinge axis 141 of the front connection part 121 is positioned in parallel.

Next, as shown in Figures 3b and 4b, the connection plate 142 of the main front connection part 121 is inserted into the fitting groove 132 of the temple connection part 113, and the hinge axis 141 of the main front connection part 121 is inserted. When inserted into the insertion groove 133 of the temple connection part 113, the temple 120 can be easily assembled into the temple connection part 113 of the main front 110.

That is, in the temple hinge connecting device 100 for an eyeglass frame according to the present invention, the inner upper surface of the upper insertion groove 133 and the inner lower surface of the lower insertion groove 133 of the temple connecting portion 113 are formed as inclined surfaces, The upper surface of the upper hinge axis 141 and the lower surface of the lower hinge axis 141 are formed with corresponding inclined surfaces.

And the thickness (T) between the rear end of the upper hinge axis 141 and the rear end of the lower hinge axis 141 is equal to the inner end of the upper insertion groove 133 of the temple connection portion 113 and the inner end of the lower insertion groove 133. It is set larger than the width (S) between them.

Therefore, when the hinge axis 141 of the main front connection part 121 is inserted into the insertion groove 133 of the temple connection part 113, it can be smoothly inserted along the inclined surface, and after insertion is completed, the upper part as shown in Figure 3b. The upper and lower rear ends of the hinge shaft 141 are caught in the hinge connection hole 131, so that the temple 120 cannot be separated from the temple connection portion 113 of the main front 110. A solid assembled state can be maintained.

Meanwhile, in the temple hinge connection device 100 of an eyeglass frame according to the present invention, the temple 120 has a hinge axis 141 in the left and right directions centered on the hinge connection hole 131 of the temple connection part 113 of the main front 110. It is folded while rotating. When the temple 120 is rotated toward the main front 110 and folded, the inside of the rear chamfered surface of the hinge axis 141 and the outside of the front chamfered surface of the hinge shaft 141 are in contact with the hinge connection hole 131, as shown in FIG. 4C. It is caught by the arc-shaped locking protrusions 134 protruding on both sides of the interior, allowing the temple 120 to maintain a stable folded state, and when the temple 120 is rotated to the opposite side and unfolded to wear glasses, the hinge axis (as shown in Figure 4d) The inner side of the front chamfered surface and the outer side of the rear chamfered surface of 141) are caught by the arc-shaped locking protrusion 134 of the hinge connection hole 131, allowing the temple 120 to maintain a stable unfolded state.

In this way, the temple hinge connection device 100 of an eyeglass frame according to the present invention not only allows the temple 120 to be conveniently hinged to the main front 110, but also prevents the temple 120 from being separated from the main front 110 during use. It can be rotated and unfolded or folded stably without any concerns.

In addition, the temple hinge connection device 100 for an eyeglass frame according to the present invention can stably maintain the folded and unfolded state of the temple 120 through the arc-shaped locking protrusion 134 provided in the hinge connection hole 131, thereby maintaining the eyeglasses. It becomes easy to store and wear.

Although the invention made by the present inventor has been described in detail according to the above-mentioned embodiments, the present invention is not limited to the above-described embodiments and can of course be changed in various ways without departing from the gist of the invention.
