Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a connecting device and a connecting method between spectacles and detachable (clip-on) sunglasses, and particularly relates to a connecting technique between a detachable sunglass having no arm for detachably connecting to spectacles and spectacles. is there.

[0002]

[Prior art]

 In general, eyeglasses are used to enhance the vision of people with low vision, and sunglasses help protect eyes from strong, unsightly light. Normally, eyeglasses include a lens frame whose inner ends are connected to each other by a noise frame, and a lens is fitted into each lens frame, and an arm (vine) is attached to an outer end of the lens frame via a hinge. .

[0003] Visual acuity is classified into normal vision, myopia, hyperopia and astigmatism. Myopia is present if the incoming parallel rays are focused in front of the retina. This makes it easier for the viewer to see things near, but not so far away. By using concave lenses in spectacles, myopia can be properly corrected.

[0004] There is also hyperopia if the incoming parallel rays are focused after the retina. This makes it difficult for viewers to see things near them and things far away. In the case of astigmatism, the cause is that the spherical surface of the eyeball, especially the cornea, is not uniform, and the incoming parallel rays are not directly focused at one point on the retina, so that the viewer is focused on the field of view. I don't know.

[0005] As described above, spectacles are used for correcting vision, but on the other hand, in midsummer, when ultraviolet rays are strong, spectacle users want sunglasses equipped with corrective lenses. In other words, unlike sunglasses worn by people who do not have poor vision, those wearing spectacles due to poor refraction of the eye will need another sunglass with a vision correction lens that corresponds to the eyeglass lens they usually use. Yes, but this is expensive.

[0006] In order to solve this problem, by attaching detachable sunglasses without an arm (vine) and with a colored lens (glass) to the front of the eyeglasses, it is possible to use ordinary sunglasses with a prescription. Similar corrected vision is obtained.

FIG. 9 is a cross-sectional view illustrating a state in which conventional glasses and detachable sunglasses are connected to each other. The spectacles 10 include a first lens frame 2 whose inner ends are connected to each other by a first nose frame 3, a lens 1 fitted to each first lens frame 2, and a first lens frame 2. And an arm (vine) 4 attached to the outer end of the body via a hinge 5. In addition, the detachable sunglasses 20 include a second lens frame 22 whose inner ends are connected to each other by a second nose frame 23, and a colored lens 21 (without degree) fitted to each second lens frame 22. Prepare.

In order to connect the spectacles 10 and the detachable sunglasses 20 to each other, the first nose frame 3 of the spectacles 10 and the second nose frame 3 of the detachable sunglasses 20 have accommodating recesses 25 and 26, respectively. The permanent magnets 27 and 28 are formed and inserted into the receiving recesses 25 and 26, respectively, whereby the detachable sunglasses 20 are stably connected to the glasses 10 by the magnetic effect of the permanent magnets 27 and 28. .

However, the connection structure between the glasses 10 and the detachable sunglasses 20 has the following disadvantages. That is, since the accommodating recesses 25 and 26 for accommodating the permanent magnets 27 and 28 are limited to the eyeglasses 10 and the detachable sunglasses 20, respectively, the first and second nose frames 3 and 23 become large, and The design flexibility of the detachable sunglasses 20 is restricted. Furthermore, the larger first and second noise frames 3 and 23 and the permanent magnets 27 and 28 increase the total weight of the combination including the glasses 10 and the detachable sunglasses 20, and make the wearing comfort worse. .

Further, since the permanent magnets 27 and 28 are mounted on the first and second nose frames 3 and 23 of the spectacles 10 and the detachable sunglasses 20, respectively, the assembling work is performed by permanent magnets. Care must be taken while paying attention to the directional characteristics of the magnets 27 and 28, which makes assembly difficult and reduces productivity. In the worst case, if the permanent magnets 27 and 28 are incorrectly assembled, it becomes impossible to connect the glasses 10 and the detachable sunglasses 20.

FIG. 10 shows a magnetic flux distribution between the glasses 10 and the detachable sunglasses 20. When the pair of permanent magnets 27 and 28 are used to connect the spectacles 10 and the detachable sunglasses 20 to each other, the N pole and the S pole of the permanent magnets 27 and 28 are adjacent to each other, and between them. Due to the resulting attraction, they are properly bonded to each other. However, since the magnetic force generated in the north and south poles of the permanent magnets 27 and 28 is maintained in an open state, the magnetic force is diffused and lost to the outside. Thereby, the coupling force between the glasses 10 and the detachable sunglasses 20 is considerably reduced.

[0012]

 Accordingly, the present invention has been made to solve such a conventional problem, and an object of the invention is to make it possible to easily connect spectacles and detachable sunglasses, and to manufacture the connecting means. Another object of the present invention is to provide an eyeglass-removable sunglass connection structure that simplifies the assembly process, reduces the cost of eyeglasses and detachable sunglasses, and increases their design flexibility.

The present invention also enhances the productivity and quality of the glasses and the detachable sunglasses, prevents the detachable sunglasses connected to the glasses from being undesirably connected to the glasses, and improves the usability of the user. Things.

[0014]

[Means for Solving the Problems]

 To this end, there is provided, in accordance with one aspect of the invention, an apparatus for connecting spectacles and detachable sunglasses to each other. The glasses have a first lens frame joined together by a first nose frame at each inner end, a lens mounted on each of the first lens frames, and a hinge at an outer end of each first lens frame.
