Description

[Detailed description of the invention] This invention is an improvement to the hinge of the eyeglass temple attachment part.

In order to prevent glasses from slipping off while wearing, it is known that the temples have spring properties or springs are inserted in the hinges, but these all tend to lose their effectiveness as the period of use increases. The disadvantage was that it decreased.

This idea was devised for the purpose of attaching a magnet to the hinge and using its repulsion and attraction to apply pressure to the temples to prevent them from slipping down when wearing glasses, and to further secure them when folded. It is what was done.

To explain the structure of the present invention with reference to the drawings, Fig. 1 is a partial schematic diagram of the glasses with the hinge of the invention attached, Fig. 2 is a front view of the hinge for glasses according to the invention when it is unfolded, and Fig. 3 is a half of the hinge. 4 is a front view, FIG. 5 is a right side view, FIG. 6 is a plan view of the other half of the hinge, FIG. 7 is a front view, and FIG. 8 is a left side view.

In the drawings, reference numeral 1 denotes a hinge half-part structure, and a first upright surface 2 and a second upright surface 3 are provided at the upper and lower portions of the axis of the shaft-attached portion, respectively.

Reference numeral 6 designates the other half of the hinge, which has horizontal surfaces 7 on the sides and lower part of the axis of the shaft-attached portion that come into contact with the first upright surface 2 when the hinge is bent, and the second upright surface when the hinge is unfolded. A third upright surface 8 is provided opposite to the first upright surface 2 and the horizontal upright surface 7, and magnets 4 and 9 are buried in the first upright surface 2 and the horizontal upright surface 7, respectively, with different polarity surfaces facing each other. magnets 5 and 1, respectively, with the same polar surfaces facing the

In addition, in the figure, 11 is the hinge axis, 12 is the axis center line, and 13 is the hinge axis.
indicates the front frame of the glasses, and 14 indicates the temple.

When the glasses with the hinge of the present invention are worn, the magnets 5 and 10 embedded in the lower upright surfaces of both components 1 and 6 face each other with the same polar planes (N and N or S and S). The temples 14 work against each other so as to come into pressure contact with the sides of the face, and are prevented from slipping down as much as possible.

Furthermore, since the magnets 4 and 9 embedded in the upper upright surface and the side horizontal surface of both structures are opposed with different polarity surfaces (N and S or S and N), when the temple 14 is folded, the opposing surfaces are in close contact with each other. Since the device is held in this state, there is no risk that the handle will open and interfere with operation when stored in a case, pocket, etc.

The magnetic hinge of the present invention does not lose its function over time compared to conventional spring-like temples or hinges with springs, so that glasses can be worn comfortably for a long period of time.
