Each pair of fixing articles outward each pair of extension through holes are respectively inlaid in each pair of receiving rooms in both distal ends of each curved portion of each temple, and each curved portion is caught in each curved opening of each connecting element, so as for each temple to be pivotally coupled to each end of the lens as well as each connecting element.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is related to a coupling structure for a pair of eyeglasses, with innovatory convenience and comfort features, and more particularly to a coupling structure in which connecting elements are used for completing the pivotal connection between a one-piece lens and temples.
2. Description of the Related Art
As the continuous development of technology, various new products are emerged in the current market. Eyeglasses also become an indispensable device in the daily life of modern people. Eyeglasses for myopia, presbyopia and vision correction emphasize practicality, eyeglasses for industry use, sunglasses and windproof eyeglasses emphasize functionality, and stylized eyeglasses emphasize aesthetic appearance and fashion.
In addition to the practicality, functionality or aesthetic appearance, a pair of eyeglasses must be worn comfortably. A most common style of eyeglasses in the current market is a pair of eyeglasses with only a pair of lenses or a one-piece lens. This kind of frameless eyeglasses is popular with most people because it is light to be worn. However, it is still not so comfortable to wear a pair of frameless eyeglasses because the lenses or temples may touch a wearer's face.

Therefore, in order to solve the above-mentioned problems, the present invention is to provide a coupling structure for a pair of eyeglasses that substantially obviates the drawbacks of the related conventional art.
A primary objective of the present invention is to provide a coupling structure for a pair of eyeglasses, in which connecting elements are used for completing the pivotal connection of a one-piece lens and temples.
Another primary objective of the present invention is to provide a coupling structure for a pair of eyeglasses, which is assembled with a simpler method for saving time and manpower cost spent in assembly and disassembly.
Still another primary objective of the present invention is to provide a coupling structure for a pair of eyeglasses, whose connecting elements are made of soft material so as for a wearer to feel comfortable when the connecting elements being in contact with a wearer's face.
Yet another primary objective of the present invention is to provide a coupling structure for a pair of eyeglasses, which provides better effects of tight and pivotal connection between a one-piece lens and temples.
According to above objectives, the present invention provides a coupling structure for a pair of eyeglasses. The coupling structure includes at least a one-piece lens, at least a pair of connecting elements and at least a pair of temples. Each pair of fixing articles are inserted through each curved groove of each connecting element and respectively into and through the extension through holes in both distal ends of each curved groove, so as for each pair of fixing articles to respectively protrude outward both extension through holes, and each flange in each hollow is caught in each concave of each curved groove so as for each connecting element to be firmly coupled to each end of the lens. Each pair of fixing articles outward each pair of extension through holes are respectively inlaid in each pair of receiving rooms in both distal ends of each curved portion of each temple, and each curved portion is caught in each curved opening of each connecting element, so as for each temple to be pivotally coupled to each end of the lens as well as each connecting element. While the pair of eyeglasses with the coupling structure of the present invention being worn, a wearer will feel comfortable because each attachment piece of each connecting element provides soft and tender contact with the face of a wearer.
