## Background
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention is related to a pair of eyeglasses, and more particularly, to a pair of eyeglasses in which engaging element and connecting element are used for completing the pivotal connection between lens and temple.
2. Description of Prior Art
From eyeglasses for myopia, presbyopia, and vision correction emphasizing practicality, eyewear for industry use, sunglasses, and windproof eyeglasses emphasizing functionality, to stylized eyeglasses emphasizing aesthetic appearance and fashion as mainstream, eyeglasses almost become an indispensable device in the daily life of modern people. And the most common style of eyeglass in the current market is a pair of eyeglasses with an eyeglass frame to support a pair of lens (framed eyeglasses) or with only a pair of lens (frameless eyeglasses), wherein the temples are pivotally connected to the left and right opposite sides of the frame (lens) with screw. However, when eyeglasses pivotally connected in such way are used for a long time, the screw may become loose or worn and thus lead to loosening of temples. At this moment a supplementary tool (screw driver) is needed to back the screw out or drive the screw in for further reparation or taking-apart. However, not only does such process of taking-apart take much time and efforts, but it is also easy for screw to be indirectly damaged and thus become unusable when being backed out or driven in. And if there is no supplementary tool at hand, then the replacement cannot be done at all, which causes much inconvenience.
In addition, when this type of eyeglass is produced by ordinary eyeglass manufacturers, it is often needed to complete the pivotal connection of eyeglass frame (lens) and temples by handwork. Therefore in addition to the cost of raw materials, there will also be extra cost of manpower for performing this handwork, and thus the production cost cannot be decreased and the competitiveness in the industry is lost.
BRIEF SUMMARY OF THE INVENTION
In order to solve above-mentioned problems, one primary objective of the present invention is to provide a pair of eyeglasses, in which engaging element and connecting element are used for completing the pivotal connection of lens and temples and which reduces complexity in assembling.
Another primary objective of the present invention is to provide a pair of eyeglasses which is assembled with a simpler method for saving time and manpower cost spent in completing pivotal connection and disassembly.
Still another primary objective of the present invention is to provide a pair of eyeglasses, the engaging element and connecting element of which can be disposed respectively on lens and on temples and which provides better replaceability.
Yet another primary objective of the present invention is to provide a pair of eyeglasses, the engaging element and connecting element of which can be disposed respectively on lens and on temples and which provides better effect of pivotal connection.
According to above objectives, the present invention provides a pair of eyeglasses in which pivotal connection between lens and temples are completed by using engaging element and connecting element. The pair of eyeglasses comprises at least a lens, at least a pair of temples, at least a pair of engaging element, and at least a connecting element. The lens includes at least a pair of engaging elements disposed on the left and right opposite sides of the lens, and the engaging elements include a C type engaging portion. The pair of temples include at least a connecting element disposed at one end of the temples to be pivotally connected to the engaging elements of the lens, and the connecting element includes at least a connecting pillar and is at least partially suspended. Wherein when the connecting element and the engaging elements are pivotally connected to each other, the connecting pillar of the connecting element is disposed in the C type engaging portion for the pivotal connection of the lens and the temples to be completed in a simple and fast way.
Since the assembly method of the pair of eyeglasses of the present invention in which engaging element and connecting element are used to complete pivotal connection of lens and temples is simpler, the time and manpower cost spent in completing pivotal connection and disassembly can be greatly reduced. And also because the pair of eyeglasses is assembled by several components, if one of the components cracks or is worn out and leads to damage, only the damaged component needs to be replaced individually and no unnecessary waste will be generated.

The connecting pillar 411 can be roughly in the shape of a square structure, a round structure, or with at least a chamfer angle for corresponding to the inner surface 812 of the C type engaging portion 811. Wherein when the connecting elements 41 and the engaging elements 81 are pivotally connected to each other, the connecting pillar 411 of the connecting elements 41 is disposed in the C type engaging portion 811 for the pivotal connection of the lens 11 and the temples 21 to be completed in a simple and fast way. Moreover, when the inner surface 812 of polygon structure of C type engaging portion 811 and the connecting pillar 411 of the square structure are pivotally connected to each other and turned, a interference effect can be formed for the temples 21 to achieve the effect of locating when rotating. And since the top supporting piece 813 disposed on the C type engaging portion 811 includes surface with multiple curvatures or different slopes, therefore when the temples 21 adduct, there will be interference effect of different degrees generated between the surface of top supporting piece 813 and the connecting elements 41 as the adduction angle of temples 21 changes for the temples 21 to have the function of interlocking and locating when being located on the lens 11.
The pair of eyeglasses of the present invention is assembled in a simpler way by using engaging element and connecting element for completing the pivotal connection of lens and temples, and therefore time and manpower cost spent in completing pivotal connection and disassembly can be greatly saved. Moreover, because the pair of eyeglasses is assembled by several components, if one of the components cracks or is worn out and leads to damage, only the damaged component needs to be replaced individually and no unnecessary waste will be generated.
While the invention has been described by way of examples and in terms of the preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. To the contrary, it is intended to cover various modifications and similar arrangements as would be apparent to those skilled in the art. Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
