[Prior Art] Conventional glasses generally have a lens body and two temples, and the lens body can be a lens or a combination of a frame and a lens, and the two temples are respectively disposed on one side of the lens body, and the glasses can be expanded or folded so that the glasses can be expanded or folded It is worn or stored and carried; the main body and the temples are designed to match the head shape of the human head and can prevent the main body of the glasses and the temples from pressing the human face and the side of the head. Causes discomfort. The sixth figure shows one of the conventional eyeglass structures, which mainly has a lens main body 1 ', two temples 2'' and the eyeglass main body 1' and the two temples 2, respectively, which are matched with the human head type design with curvature, and The two sides of the main body of the lens are respectively pivotally connected by the engaging element 3' and the end of the temple 2', and the two-leg 2 can be rotated or unfolded by the engaging element 3' as a pivotal corresponding to the main direction of the eyeglass. However, since the two temples 2' are designed in Thai, the temples 2' are greatly convexly protruded from the rear of the lens main body 丨', and the ends of the lens main body 具 have the first parallel line A, and a second parallel line B' having a central outer edge parallel to the first parallel line A and a third parallel line C' parallel to the first parallel line A after the folded outer edge of the lens main body ' Increasing the distance D' from the main body 1' itself causes an increase in the folded volume, and causes the folded glasses to be easily placed in the pocket of the clothes or other small space, which is inconvenient to carry, and the volume of the case must be larger than the size of the case. The folded eyeglass volume will also cause the glasses case Should be increased is missing. Form No. A0101 Page 3 of 18 Page 0992016591-0 201133054 In order to improve the above situation, the conventional structure has the lens body itself or the temple foldable design. However, the lens body can be folded down to greatly reduce the structural strength of the glasses itself. The glasses disclosed in U.S. Patent No. 5638146 disclose that the two mirror legs can be respectively folded on the upper and lower sides of the lens body. However, the structure will still increase the distance between the upper and lower glasses, and cannot effectively reduce the volume after folding. Further, as shown in the seventh figure, the U.S. Patent No. 6,375,323 discloses that the inner concave portion 41 is disposed under the frame of the lens main body 4', and the temple 5 is folded into the inner concave portion 41 when folded. Reducing the folded volume, however, the foregoing design will destroy the shape integrity of the lens body 4, and the lens body 4' will be difficult to set the shape of the inner concave portion when the lens is purely a lens, and the eye will be recorded after the eye is removed. "The splicing position 51 is still convex to the spectacles main body 4, ❹, and corresponds to the sixth figure, the seventh figure of the glasses has the first, second, and third parallel lines e, F, G, and the folded temples 5' will increase the convexity distance of the main body 4 of the glasses itself, the beauty of the 68th7Η) glasses reveal the meaning ^ ^ brother chat can be folded in front of the main body of the glasses and "by the temples on the lens of the lens body (four) role, however, the mirror _ After the combination will be in the head ^ (four) ^, still with a folded body material can effectively reduce the missing.
