REPLACEMENT STRUCTURE OF EYEGLASSES LENS

A replacement structure of eyeglasses lens is disclosed. A frame comprises two circular openings corresponding to each other, at least one recess at the periphery of each circular opening, and a sliding slot connected with the recess. A lens rim is around the lens periphery, wherein the rim shape is circular to correspond to the circular opening for assembling the rim in the circular opening, and a projection is protruded from the rim periphery to correspond to the recess and embedded in the recess. When the rim is rotated, the projection is moved into the sliding slot to fasten the lens. Accordingly, the assembly and disassembly of the lens with the frame does not require any tools, being simpler, easier, and faster. Furthermore, the different color and style of the rim is used to match with the frame, so the use is richer and more is varied to attract consumers' attention.

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a replacement structure of eyeglasses lens. More particularly, the replacement structure of eyeglasses lens is not only that the assembly and disassembly procedure of the lens with the frame does not require tools, so the procedure is simpler, easier, and faster, but also that the different color and style of the rim is used to match with the frame, so the use is richer and more varied to attract the consumer's attention, which the replacement structure of eyeglasses lens has more product competitiveness and is increased in practical characteristic.

Description of Related Art

The general glasses are divided into optical glasses, sunglasses, sport spectacles, and safety glasses, according to their uses and function. The frame design of different type of the glasses is different. For example, in the full-rim glasses, the lens is all received in the frame to protect the safety of the lens, so the full-rim glasses are used in optical glasses with expensive lens. However, the half-rim glasses is lighter than the full-rim glasses, so it is used in sunglasses, sports spectacles, and safety glasses, which emphasis in light weight and well-executed, for user doing sport, outside exercise, or construction.

Whatever the glasses is applied for, the basic structure of the glasses comprises the lens assembled with the frame. The lens is assembled with the assembly hole of the frame and fixed in the screw hole in the assembly hole of the frame by the screws, so the lens is held between the assembly holes of the frame. Then, the temples are pivoted with the two sides of the frame to complete the assembly of the glasses.

The lens of the foregoing glasses is fixed between the assembly holes of the frame by screws; however, in the actual use, it requires the tools for assembling the lens with the frame or separating the lens from the assembly holes. It is inconvenient to assemble or separate the lens, if the user does not have the proper tool in hands, it results that the lens cannot be assembled with or separated from the frame.

SUMMARY OF THE INVENTION

Accordingly, the object of the present invention is related to a replacement structure of eyeglasses lens. In which, not only that the assembly and disassembly procedure of the lens with the frame does not need the tools, so the procedure is simpler, easier, and faster, but also that the different color and style of the lens rim is used to match with the frame, so the use is richer and more varied to attract the consumer's attention. The replacement structure of eyeglasses lens has more product competitiveness and is increased in practical characteristic.

For the above object, a replacement structure of eyeglasses lens comprises a frame and a lens. The frame comprises two circular openings corresponding to each other, at least one recess at the periphery of each circular opening, and a sliding slot connected with the recess. A lens rim is firmly around the periphery of the lens, wherein the shape of the lens rim is circular to correspond to the circular opening for assembling the lens rim in the circular opening, and a projection is protruded from the periphery of the lens rim to correspond to the recess at the periphery of the circular opening and embedded in the recess. When the lens rim is rotated, the projection is moved into the sliding slot to fasten the lens.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Please refer toFIG. 1, which is an exploded perspective view of a replacement structure for eyeglasses lens according to an embodiment of the present invention. The replacement structure for eyeglasses lens comprises a frame1and two lenses2.

The frame1comprises two circular openings11corresponding to is each other, at least one recess12at the periphery of each circular opening11, and a sliding slot13connected with the recess12.

A lens rim21is firmly around the periphery of each lens2, wherein the shape of the lens rim21is circular to correspond to the circular opening11of the frame1for assembling the lens rim21in the circular opening11. A projection22is protruded from the periphery of the lens rim21to correspond to the recess12at the periphery of the circular opening11.

Please also refer toFIG. 2, which is a schematic diagram of a replacement structure for eyeglasses lens when it is assembled according to an embodiment of the present invention. When the replacement structure of eyeglasses lens of the present invention is assembled, the lens rim21, which is firmly around the periphery of each lens2, is corresponded to the circular opening11of the frame1, and the projection22at the periphery of the lens rim21is corresponded to the recess12at the periphery of the circular opening11, then, the lens rim21is assembled in the circular opening11and the projection22is embedded into the recess12. Next, the lens rim21is rotated toward the sliding slot13, which is connected to the recess12, so the projection22is moved into the sliding slot13to embed the projection22to the sliding slot13, please refer toFIG. 3, which is a schematic diagram of a replacement structure for eyeglasses lens after it is assembled according to an embodiment of the present invention, and then, the lens rim21together with the lens2is assembled in the circular opening11of the frame1, please refer toFIG. 4, which is a schematic diagram of a replacement structure for eyeglasses lens after it is assembled according to an embodiment of the present invention.

Accordingly, the lens2with the lens rim21is not only directly rotated to be assembled in the circular opening11of the frame1, when the lens is replaced, the lens2with the lens rim21is also directly rotated to drive the projection22move toward the recess12, making the projection22separate from the recess12to take out the lens2together with the lens rim21from the circular opening11of the frame1, whereby the lens2is replaced.

According to the above description and embodiments, comparison with the prior art, the replacement structure of eyeglasses lens of the present invention has the advantages as following:

1. The lens with the lens rim of the present invention are rotated in the circular opening of the frame to assemble the lens with the lens rim in the circular opening or to separate from the circular opening, so it does not require the tools during the assembly or disassembly of the lens and the frame, making the procedure of assembling or disassembling the lens and the frame simpler, easier, and faster.

2. Because the outer edge of the lens has the lens rim, the different color and style of the lens rim is used to match with the frame, making is the use richer and more varied to attract the consumer's attention, the replacement structure of eyeglasses lens has more product competitiveness.
