ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a magnetic coupling system, and more particularly to a coupling system which is provided with forceful magnets for pivotally securing a temple to an eyeglass hinge.
2. Description of the Related Art
Referring to
FIG. 3
, a conventional coupling system for securing a temple
92
to a hinge
901
of an eyeglasses
90
includes the hinge
901
and the pivotal member
921
at the front end of the temple
92
. The hinge
901
is provided with holes
902
in the pivotal member of the hinge
901
, and the pivotal member
921
of the temple
92
is provided with a hole
922
in the center. After the pivotal member
921
being inserted in the pivotal member of the hinge
901
, a screw
93
is screwed through the holes of
902
and
922
so as to pivotally secure the temple
92
to the hinge
901
of the eyeglasses
90
.
However, after being used for a period of time, the screw
93
will be gradually loosen because the frequent movement of the temple
92
. If a wearer is unwary of the loosen screw, the eyeglasses
90
worn by the wearer will fall down at any time.
SUMMARY OF THE INVENTION
Accordingly, an objective of the present invention is to provide a magnetic coupling system which is convenient for pivotally securing a temple to a hinge of an eyeglasses.
Another objective of the present invention is to provide a magnetic coupling system whose forceful magnets are inlaid in the pivotal flanges of the eyeglass hinge and the temple so as to pivotally couple the temple to the eyeglass hinge in a magnetically reinforced manner.
To achieve these advantages, a magnetic coupling system for securing a temple to an eyeglass hinge in the present invention includes a pivotal flange on the rear end of the eyeglass hinge and one clipping structure formed on the front end of the temple. One coupling magnet is provided in the pivotal flange of the eyeglass hinge. The clipping structure includes a pair of opposed pivotal flanges spaced one from the other to capture the pivotal flange of the eyeglass hinge therebetween and two magnets respectively secured in the pair of opposed pivotal flanges for respective magnetic coupling to the coupling magnet in the pivotal flange of the eyeglass hinge. Therefore, the temple is pivotally coupled to the eyeglass hinge in a magnetically reinforced manner.
