It can also be made of a spring, a metal, resin, rubber, or the like, which has an extremely strong elasticity.

Further, as described in claim 3, the connecting main shaft 2 and the link mechanism 3 are provided with an attaching / detaching mechanism 8 so as to be detachable.

Further, one or more magnets and magnetic bodies 10 are relatively mounted at arbitrary positions on the apron frame 6, the eyeglass frame main body 1 and the temple 4, as described in claim 4, and the magnet and the magnet Magnetic body 10
The front hanging frame 6 can rotate and move relative to the eyeglass frame main body 1 and the temple 4 due to the magnetic attachment, and the front hanging frame 6 can be attached to and detached from the plurality of arbitrary positions of the eyeglass frame main body 1 by suction. Structured.

FIG. 5 shows an example in which the release mechanism 9 for releasing the suction is realized by making the release mechanism elastic body 13 function between the bridge 11 and the pad 12. In this case, the glasses are used. When the bridge 11 is pressed while the frame body 1 is attached to the face, the pad 12 and the release mechanism elastic body 13 connected to the pad 12 push up the forehead frame, thereby expanding the gap between the eyeglass frame body 1 and the forehead frame 6 and magnetizing. In this case, the release mechanism elastic body 13 is connected to the bridge 11,
It can be applied to any position between the spectacle frame 1 and the front frame 6 other than between the pads 12.

FIG. 2 shows a detachable mechanism 8 according to a third aspect of the present invention, in which the connecting main shaft 2 and the link mechanism 3 are formed so as to be relatively fitted into each other, and a detachable magnet and a magnetic body 14 are provided at their respective ends. This is an embodiment in which attachment and detachment are enabled by the suction force.

Further, as shown in FIG. 3, a notch 15 is relatively formed in the connecting main shaft portion 2 and the link mechanism portion 3 as an attaching / detaching mechanism 8 so that an elastic force is exerted in the circumferential direction, so that the connecting main shaft portion 2 and the link mechanism portion are formed. It is also conceivable that the fitting claw 16 is provided relatively to the third member 3 so that it can be attached and detached.

FIG. 4 shows the link mechanism 3 according to the first embodiment.
This is an embodiment in which the front frame 6 is rotated in an inverted manner without having the frame.

FIG. 4 also includes an elastic body 7, and FIG.
The mechanism is detachable as shown in FIG.

[0020]

Since the present invention is configured as described above, it has the following effects.

According to the mechanism of the first aspect, the front lens is rotated in the reverse direction, and an effect that the back of the lens surface is exposed at the temple position on the side surface of the main body frame can be obtained.

Since the link mechanism is provided as in the mechanism of the second aspect, the front frame can be rotated and moved laterally while keeping the same lens surface.

Since the elastic body acts in the rotation direction,
An automatic rotation driving force can be obtained.

According to the third aspect, the front hanging frame is detachable.

According to the fourth aspect of the present invention, the forehead frame obtains a rotation and lateral movement relative to the temple and magnetically attaches to the temple by magnetically attaching the magnet and the magnetic body. By taking a long distance, it is possible to obtain the effect of sliding and moving while following the change in the magnetic attachment point caused when the temple is folded.

According to the release mechanism of the fifth aspect, the crisp magnetic release of the front hanging frame can be performed.
