Description

  The present invention relates to a front-frame-replaceable spectacle that allows anyone to easily attach and detach a front frame having a different shape and material, and to enjoy the design of glasses by replacing the front frame, and to enhance the practicality.

  Conventional spectacles for attaching / detaching a front frame have been considered to be attached / detached using a magnet or to be attached / detached with a clip.

  For this reason, since a magnet or a clip is attached to the spectacle frame or the spectacle front frame, an extra process may be required or the appearance of the spectacle frame as a whole may be impaired.

In addition, there is a drawback that the front frame comes off due to impact.

  The problem to be solved was to easily attach and detach the spectacles front frame 4 to the spectacle frame 1 and maintain an appearance that is the same as that of general spectacles when the spectacles frame 1 is attached.

Means adopted by the present invention for solving the above-described problems will be described with reference to the accompanying drawings.

That is, according to the present invention, as shown in FIG. 1, the entire spectacles 9 are divided into the spectacle frame 1 and the spectacle front frame 4, and the hook portions 2 and 3 are formed in the central portion on the back side of the spectacle frame 1. Attach the legs 5 and 6 with brazing or the like. In FIG. 2, the glasses front frame 4 is fixed to the glasses frame 1 by pinching the nose pads 7 and 8 inward, and hooking the nose foot 5 to the hook portion 2 and hooking the nose foot 6 to the nose foot portion 3.

  According to the present invention, the front frame of the spectacles can be easily detached from or attached to the spectacle frame by grasping the nose pad portion of the spectacles and curving inward. Also, if you have various glasses front frames, you can change the image and change the application by replacing them.

As shown in FIG. 1, hook portions 2 and 3 projecting in the optical axis direction of the spectacle lens are formed in the central portion on the back side of the spectacle frame 1 as a main body frame, and nose feet 5 and 6 are formed on the upper edge of the spectacle front frame 4. Attach the tip with brazing. As shown in the drawing, the intermediate portion between the tip of the nose feet 5 and 6 and the nose pad portions 7 and 8 is bent toward the inner edge from the upper edge side of the spectacles front frame 4 to form a bent portion. At this time, as shown in FIG. 2, the interval 11 of the hooked portions of the nose feet 5 and 6 is attached a little wider than the interval 10 of the hooked portions 2 and 3.

In FIG. 2, the nose pad portions 7 and 8 are pinched with the fingertips, and force is applied to the inside to make the interval 12 of the hooked portions of the nose feet 5 and 6 narrower than the interval 10 of the hooking portions 2 and 3, that is, in front of the glasses With the gap between the edge of the frame 4 and the bent part slightly widened, the spectacles front frame 4 and the spectacle frame 1 as the main body frame are moved in the optical axis direction of the spectacle lens so as to approach each other. When the hook portions 2 and 3 are inserted and the hands are released, the spectacle front frame 4 can be fixed to the spectacle frame 1 by the repulsive force of the nose feet 5 and 6 made of a spring material.

As a modified embodiment of the present invention, FIG. 3 shows holes 16 and 17 on both sides of the bridge of the front spectacle frame 13. Pins 18 and 19 with notches as shown in the figure are attached to the central portion on the back side of the spectacle frame 14 by brazing or the like. At this time, the hole of the bridge is made slightly larger than the thickness of the pin, and the distance between the pins 18 and 19 and the distance 21 between the holes 16 and 17 of the bridge are the same. As in the embodiment, the nose pads 7 and 8 are engaged with the increments of the knob pins 18 and 19 so that the nose feet 5 and 6 engage as shown in the enlarged view in the direction b.
Thereby, the stability was further increased.

As shown in FIG. 4, the appearance is not impaired by adjusting the position of the bridge 15 to the height of the glasses 14.
