Description

Lens clamp structure

Technical Field

The present invention relates to a lens clamp structure, and more particularly to a lens clamp structure attached to a frame for a spectacle.

Background

For the myopia group, the sunglasses for correcting the eyesight are worn, so the sunglasses cannot be worn at the same time, and the solution is that the sunglasses with the diopter are directly matched in another way besides the contact lenses, but the contact lenses cannot be accepted by the myopia group due to the problems of adaptability, time consumption in wearing, easy eye diseases caused by improper cleaning and the like, and the sunglasses matched with the diopter are not adopted due to the problems of diopter limitation, high cost, discomfort indoor occasions and the like.

To solve these problems, the industry has developed an attached lens made of polarized lenses, so as to attach to the front side of the existing myopia glasses, and to integrate the functions of sunglasses on the myopia glasses, so as to solve the use requirements of myopia people for sunglasses, and there are many kinds of attached lens structures in the industry, as follows:

1. taiwan patent publication No. M368086 discloses an elastic clip of a sunglass lens, which is formed by connecting a bridging element between two sunglass lenses, and is mainly characterized in that: an elastic clip is provided on the bridging element, so that the user can firmly clip on the middle beam of the main frame by using the elastic clip to fix the sunglasses lens on the main frame.

2. Taiwan patent No. M429112 discloses a detachable auxiliary sunglasses, which is combined with a holding device of the sunglasses, and a structure of an externally-hung sunglasses of a pair of ordinary eyeglasses is mounted on the sunglasses by using the holding device.

3. The taiwan patent No. M329178 is an externally-hung sunglasses, which includes a pair of sunshade lenses, the middle of the sunshade lenses is connected by a middle beam, the middle beam includes two ends of the middle beam, extending portions are respectively arranged along the sunshade lenses, each extending portion is provided with at least two vertical protruding columns for combining the sunshade lenses, each extending portion is provided with an elastic convex buckle which is vertically protruded inwards and used for buckling the glasses frame, and the rear edge of the middle beam is provided with a groove hook with a downward opening for hooking the middle beam of the glasses, so that the externally-hung sunshade lenses can be stably hooked on the glasses frame and tightly combined together, or the two can be quickly separated.

However, the above-mentioned clamping mechanism and the additional lens are mostly directly molded or locked together, so that other additional lenses cannot be replaced, that is, each additional lens has an independent clamping mechanism, which is inconvenient to use, and the locking process has disadvantages of troublesome assembly, increased working hours, etc. for manufacturers.

Accordingly, the inventor of the present invention has studied and improved the existing structure and defects with the help of the abundant design development and practical manufacturing experience of the related industry for many years, and provides a lens clamp structure to achieve the purpose of better practical value.
