Abstract

(57) [Summary] [Purpose] The purpose is to strengthen the lenses of rimless glasses. [Structure] An elastic cushion material made of resin was wrapped around the periphery of the lens. [Effect] By strengthening with the cushioning material, cracking and chipping from the peripheral edge can be prevented, and the lens is less likely to be damaged.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of rimless glasses.

[0002]

[Prior Art]

 Rimless spectacles, which are constructed by screwing the lens directly to the bridge, wisdom, etc. without the use of a cold and hard metal rim, have a wide field of view, are smart, and feel calm, so they are popular. is doing. However, since there is a general premise that a transparent material must be used for the lens, many brittle materials are used. However, there was a problem that it was easily chipped.

In addition, when such rimless spectacles are used for a long period of time, due to lack of strength of the lens, a defect occurs around the connecting portion between the lens and the bridge or wisdom, which causes various obstacles in the connecting portion. There was a problem that was caused.

[0004]

[Problems to be solved by the device]

 The present invention has been made in view of the above problems of the conventional rimless spectacles. Therefore, it is a technical problem to provide rimless spectacles in which the lens is not easily scratched and the connecting portion is not easily damaged.

[0005]

[Means for Solving the Problems]

 Therefore, in the present invention, the periphery of the lens is surrounded by the elastic cushion material made of resin, and the bridge and the lens stopper of the tip are connected to the lens while the elastic cushion material is sandwiched between the lens and the bridge. We decided to provide rimless spectacles in which the lens is less likely to be damaged and less likely to break down by strengthening the periphery of the lens and the vicinity of the lens stop by adopting a means of directly connecting to the left and right lenses.

【Example】

 Hereinafter, the present invention will be described based on embodiments.

A concave groove 11/11 is formed around the lens 1.1, and a rubber band-like elastic cushion material 2.2 is fitted around the lens 1.1 so as to be fitted into the concave groove 11/11. After that, screw holes 12, 12, ... Are drilled in the required portions of the lens 1.1, and the lens stoppers 31, 41, 41 of the bridge 3 and the wisdom 4.4 are screwed. At the time of screwing, the elastic cushion material should be sandwiched between each lens stopper and the lens.

In this way, the contact portion of the lens with the lens stopper is protected by the elastic cushion material, and the lens is less likely to be scratched and rattling. In addition, the cushioning material has elasticity, so the lens stopper and the lens can be buffer-coupled to completely seal the gap between them and keep the lens stable even if the lens processing accuracy is not so high. There is also.

In addition to the above embodiments, various methods such as those shown in FIGS. 3 to 6 can be adopted as the method of attaching the elastic cushion material to the lens. Further, as rimless spectacles using a lens protected by such a cushion material, in addition to connecting the bridge and the wisdom separately to the lens, the bridge and the wisdom are connected by a metal wire rod. Things can also be adopted. Also, if you use colored elastic cushions, you can expect decorative effects.

[0010]

[Effect of the device]

 As described above, the rimless spectacles of the present invention have the effect of protecting the entire lens with the elastic cushioning material and preventing damage or rattling of the lens, and thus have high industrial utility value.
