Description

렌즈 고정구조가 개선된 사출안경 및 그 제조방법{Injection molding glasses and manufacturing method with improved lens fixing structure}[0001] The present invention relates to an injection lens having an improved lens fixing structure and a manufacturing method thereof,

본 발명은 합성수지재로 사출하여 만드는 사출안경에 관한 것이며, 좀 더 구체적으로는 사출방식으로 안경을 구성하면서도 렌즈를 고정하는 구조가 금속재의 경우와 같이 강한 힘으로 렌즈를 조일 수 있도록 하며, 간단한 구조 및 공정으로 제조가 가능하고 외관도 단정한 사출안경과 그 제조방법에 관한 것이다.The present invention relates to an injection eyeglass which is made by injection molding with a synthetic resin material. More specifically, it is possible to tighten a lens with a strong force as in the case of a metal material, The present invention relates to an injection eyeglass and a manufacturing method thereof.

주지된 바와 같이 안경의 재질에 따른 분류상 크게 합성수지 안경과 금속 안경으로 구분된다.As is well known, the classification according to the material of glasses is largely divided into synthetic resin glasses and metal glasses.

이러한 합성수지 안경과 금속 안경은 기본적으로 렌즈를 결합하고 고정하는 방법상에 차이가 있는데, 합성수지 안경은 재질 특성상 자체적인 수축이 가능하고 가열하면 더욱 잘 늘어나는 특성이 있으므로 렌즈를 고정시 테를 벌려 렌즈를 끼우고 자체가 수축함에 의해 렌즈가 이탈되는 것을 방지하고 있으며, 금속 안경의 경우에는 늘어나는 성질이 거의 없으므로 렌즈를 끼우기 위해 테의 일부가 절개되어 벌릴 수 있도록 구성한 다음 테를 벌려 렌즈를 끼우고 다시 절개부를 나사로 잠그는 방법을 채택하고 있다.These synthetic resin glasses and metal glasses are fundamentally different from each other in the way of combining and fixing the lenses. Since synthetic resin glasses can be shrunk by itself due to its material properties, In order to insert the lens, a part of the frame is opened so that it can be opened. Next, the lens is put in place and the lens is inserted again. In this case, A method of locking the part with screws is adopted.

이와 같은 합성수지 안경의 단점은 렌즈의 고정이 자체의 수축력에만 의지하므로 렌즈를 고정하는 힘이 부족하여 크기 않은 충격에도 렌즈가 잘 빠져버리는 문제가 있었고, 금속 안경의 경우는 강력하게 렌즈를 고정할 수 있다는 장점이 있으나, 고정을 위한 구조를 구비하는데 작업시간과 비용이 많이 필요하고, 외관상으로도 단정하지 못한 단점이 있었다.The disadvantage of such synthetic resin spectacles is that since the fixation of the lens depends only on the contracting force of the lens itself, there is a problem that the force for fixing the lens is insufficient, However, it has a disadvantage in that it requires a lot of work time and cost, and it can not be determined even in appearance.

따라서 근래에는 합성수지 안경이 많은 호응을 받고 있는 현실이고, 합성수지 안경의 디자인 다양화와 기능성에 대한 개발이 촉진되는 추세이므로 이러한 합성수지재 사출안경에도 렌즈를 강력하게 고정할 수 있는 구조가 필요하였던 것이다.Therefore, in recent years, synthetic resin spectacles have received a great deal of attention, and since the development of design diversity and functionality of synthetic resin spectacles is being promoted, a structure capable of strongly fixing the lenses to such synthetic resin re-injection spectacles was needed.

한편, 아래 선행기술문헌과 같이 종래 합성수지를 이용한 사출안경에도 금속 안경의 경우와 같이 절개부를 구성하고 고정나사를 이용하여 결합하는 구조가 제안되기도 하였으나, 결합을 위한 구성이 외부로 전부 노출되고 안경다리를 결합하기 위한 구성과 동시에 구성되므로 렌즈를 분리하기 위하여 안경다리를 동시에 분리하여야 하고 다시 렌즈 결함을 위하여 안경다리도 결합하여야 하며, 외관도 단정하지 못 한 등 많은 문제점이 발견되었다.In the meantime, as in the following prior art documents, there has been proposed a structure in which an incision part is formed by using a fixing screw, as in the case of a metallic eyeglass, even in injection glasses using conventional synthetic resins, So that it is necessary to separate the glasses legs at the same time in order to separate the lenses. In addition, it is necessary to connect the glasses legs to the lens defects again.
