Description

Multilayer lens structure of glasses

The present invention relates to a multi-layer lens structure for glasses, which mainly refers to a structure that can enhance the strength and stability of the combination of the lens and the frame.

Conventional skiing or other sports glasses to avoid fogging. The glasses are often provided with a multi-layer lens consisting of front and rear lenses, the front lens has a suitable thickness to block the external strong wind, and the rear lens and the front lens set a spacing frame. And the interval between the front and rear lenses can block the temperature of the front lens, and can avoid the fogging of the rear lens due to the body surface temperature.

In order to improve the wearing comfort, the multi-layer lens is generally designed to be thinner than the front lens to reduce the wearing weight. However, when the multi-layer lens is combined with the frame, the edge of the lens is prone to breakage at the end of the lens. Multilayer lenses cannot be combined with a stable combination of frames.

The purpose of this creation is to provide a structure that enhances the strength and stability of the composite lens combination.

The multi-layer lens of the present invention comprises a front lens, a rear lens, a spacer frame and a reinforcing frame, wherein the thickness of the rear lens is smaller than that of the front lens; and the spacer frame is a hollow annular body, and the front and rear sides are respectively behind the front lens The surface is close to the peripheral position and the front surface of the rear lens is fixed near the peripheral edge, and the front and rear lens centers are spaced apart, and the front and rear lens edges and the spacer frame have a concave ring groove; and the reinforcing frame has appropriate strength. And the hollow annular body, the front side of the reinforcing frame is fixed to the periphery of the rear surface of the rear lens, and the peripheral strength of the rear laminated lens can be improved.

The multi-layer lens of the present invention can be combined with the frame of the lens, and the front of the frame has a buckle edge which can be engaged with the concave ring groove of the multi-layer lens. When assembled, the edge of the lens can be embedded by the flexibility of the multi-layer lens and the frame. In the concave ring groove of the layer lens, the assembly process is reinforced by the reinforcing frame after the thinner lens, so that the peripheral edge of the rear lens can be prevented from being broken due to the assembly process, and the lens is combined with the reinforcing frame to increase the strength after assembling the multi-layer lens. It is then joined to the side wall of the frame to ensure that the multi-layer lens can be stably assembled on the frame when the lens is subjected to external force to improve assembly stability and reliability.

Referring to Figures 1 to 4, the laminated lens 1 of the present invention includes a front lens 11, a rear lens 12, a spacer frame 13, and a reinforcing frame 14, the rear lens 12 having a smaller thickness than the front lens 11; and the spacer frame 13 In the hollow annular body, the front and rear sides are respectively fixed to the peripheral position of the rear surface 11 of the front lens 11 and the front surface 121 of the rear lens 12, and the center of the front and rear lenses 11 and 12 are spaced apart by 130, and A concave ring groove 131 is formed between the end edges of the front and rear lenses 11 and 12 and the spacer frame 13.

The reinforcing frame 14 has a suitable strength and is a hollow annular body. The front side of the reinforcing frame 14 is fixed to the periphery of the rear surface 122 of the rear lens 12, and the peripheral edge strength of the laminated lens 1 can be improved.

The laminated lens 1 of the present invention can be combined with the frame 2 of the lens, and the front edge of the frame 2 has a fastening edge 21 which can be engaged with the concave ring groove 131 of the multi-layer lens 1. When assembled, the laminated lens 1 and the frame 2 can be assembled. The flexible buckle edge 21 can be embedded in the concave ring groove 131 of the multi-layer lens 1. The assembly process is reinforced by the reinforcing frame 14 after the thinner circumference of the lens 12, thereby preventing the peripheral edge of the rear lens 12 from being broken by the assembly process.

After the multi-layer lens 1 is assembled, the lens 12 is combined with the reinforcing frame 14 to increase the strength and then joined to the side wall of the buckle edge 21 of the frame 2 to ensure that the multi-layer lens 1 can be stably assembled on the frame 2 when the lens is subjected to an external force. Improve the stability and reliability of the assembly, and the design does not need to use the thicker lens 12 to have the combined strength and stability, and can be combined with light weight, better wearing comfort and better assembly stability.

Therefore, according to the above, the present invention can improve the better strength and good comfort of the multi-layer lens, and the foregoing embodiment is an example of the creation, and is not a limitation of the creation, and the equivalent change according to the spirit of the creation should also belong to Within the scope of this creation.
