This composition is about a combined structure of multi-layer lenses for eyeglasses, mainly referring to a multi-layer lens that can improve the strength and applicability of the structure.

It is known that skis or other sports glasses are often provided with double-layer lenses to avoid fogging. As shown in Figures 6 and 7, the double-layer lenses are composed of a front lens 1', a rear lens 2', and a spacer frame 3' , The front lens 1'has an appropriate thickness to block external strong winds; the rear lens 2'is thinner than the front lens to reduce weight; and the spacer frame 3'is a hollow ring-shaped body, and the spacer frame 3'is reared by dispensing The front surface 21' of the side and the rear lens 2'are bonded by an adhesive 5', the front side of the spacer frame 3'and the rear surface 11' of the front lens 1'are set by adhesive bonding, and the front and rear lenses 1', 2' There is a partition 4'between them.

However, because the rear lens 2'is thin, it is easy to cause the front lens 1'to be combined with the frame (not shown) before the double-layer lens. The edge of the rear lens 2'is likely to break due to improper installation, and the dispensing method is easy. The unevenness of the bonding position causes unevenness and poor bonding strength, and will cause the rear lens 2'and the spacer 3'to fall off and be missing.

In order to improve the aforementioned situation, a sheet-like double-sided adhesive tape (not shown in the figure) can be pasted on the front surface 11' of the front lens 1'and the front surface 21' of the rear lens 2'at first, and then cut out separately to remove the non-corresponding combined spacer frame. The double-sided tape at the 3'position allows the front and rear lenses 1'and 2'to be bonded to the front and rear sides of the spacer 3'by the double-sided tape respectively, so that it can have better bonding stability and flat texture, but the Adopting double-sided tape will cause obvious material waste, manufacturing environmental problems and assembly time-consuming inconvenience.

The purpose of this creation is to provide a multi-layer lens with better combined strength and applicability.

This creation includes a front lens, a rear lens, and a spacer frame. The front lens has a rear surface; the spacer frame is thicker than the rear lens and is a hollow ring body with an inner ring surface and a front surface. The torus wraps and joins the end edge of the rear lens; the front surface of the spacer frame is combined with the rear surface of the front lens, and there is a space between the front and rear lenses.

Further, the thickness of the rear lens is smaller than that of the front lens; and the front surface of the spacer frame and the rear surface of the front lens are combined by viscose bonding or snapping.

Further, the spacer frame and the rear lens can be separable and combinable components, the inner ring mask can fit the fitting groove of the end edge of the rear lens; and the spacer frame and the rear lens can also be combined by shot molding.

Further, the outer edge of the spacer frame is provided with a joint part that can be combined with the frame of the glasses, and the joint part has a buckle or a joint groove, and the frame is provided with an assembly part combined with the joint part of the spacer frame, the joint part corresponds The buckle piece of the joint part and the position of the joint groove are respectively provided with a buckle wall and an insert block.

Further, the spacer and the rear lens can be directly bonded to the soft cushion body by adhesive.

The combination of the lens edge and the spacer frame with better strength after the creation of the multi-layer lens can greatly improve the strength of the rear lens edge. Therefore, the combination process of the multi-layer lens and the frame will not cause the rear lens edge to break, and it can be better assembled Stability, and the original creation can make the buckle piece and the joint groove of the joint part of the spacer frame be combined with the buckle wall and the insert block of the joint part of the frame, which can have better combined stability.

In this creation, the spacer frame itself has much better strength than the rear lens, so the spacer frame can be combined with the frame, not only the combination of the front lens and the frame, but the creation can make the buckle of the joint of the spacer frame, The joint groove is combined with the buckling wall and the insert of the frame assembly part respectively, which can have better combination stability, and if the spacer frame and the rear lens are separable, the fitting groove of the rear lens and the spacer frame can be made It can be detached, and another different rear lens can be set up for better applicability.

The inner annular surface 31 has a fitting groove 33 that can be fitted to cover the end edge of the rear lens 2, this embodiment For example, the spacer frame 3 and the rear lens 2 are separable and combinable components, and the spacer frame 3 and the rear lens 2 can also be joined by injection molding, and after molding, the inner annular surface 31 can be wrapped. The combination of the end edge of the rear lens 2; the front surface 32 of the spacer frame 3 and the rear surface 11 of the front lens 1 are bonded by an adhesive 5 (can also be combined by snapping or other suitable methods), and the front and rear lenses 1, 2 are combined There is a spacer 4 between the spacers. The thickness of the spacer frame 3 allows the fitting groove 33 to have a spacer 4 with a proper spacing on the front side of the spacer frame 3, and prevents the temperature of the front lens 1 from being directly transmitted to the rear lens 2 for anti-fog effect.

The outer edge of the spacer frame 3 of the present invention is provided with a joint portion 34 that can be combined with the frame 6. The joint portion 34 has a fastening piece 341 and a joint groove 342, and the frame 6 has a joint portion 61 and a joint portion 34 of the spacer frame 3 In combination, corresponding to the fastening piece 341 of the engaging portion 34, the engaging groove 342 is provided with a engaging wall 611 and an insert 612, respectively.

After the creation of the multi-layer lens 10, the end edge of the lens 2 is combined with the spacer frame 3 of better strength. Therefore, the process of combining the multi-layer lens 10 and the frame 6 will not cause the end edge of the rear lens 2 to break, and may have better assembly stability.

In this creation, since the spacer frame 3 itself has much better strength than the rear lens 2, the spacer frame 3 can be provided in combination with the frame 6, and it is not necessary that only the front lens 1 and the frame 6 are combined. The engaging piece 341 and the engaging groove 342 of the engaging portion 34 are combined with the engaging wall 611 and the insert 612 of the connecting portion 61 of the frame 6 respectively, which can have better combined stability.

In this creation, when the spacer frame 3 and the rear lens 2 are in a detachable structure, the rear lens 2 can be disengaged from the fitting groove 33 of the spacer frame 3, and another lens of different colors, UV resistance, and optical power can be set according to requirements , With better applicability.

In addition, the frame of this creation can also be provided with a combination of a ring groove and the front edge of the front lens (not shown in the figure), and the front lens can also be provided with a combination of a groove and a frame combination (not shown), so this creation The frame can be combined with the spacer frame of the multi-layer lens or the front lens for better applicability.

Please refer to FIG. 5, since the edge of the rear lens 2 is reinforced by the spacer frame 3 and has good strength, the rear lens 2 and the rear side of the spacer frame 3 can be glued with glue 5 such as sponge cushion 7 or other soft cushions. The end edge of the rear lens 2 may be broken when worn. The front lens 1 or the spacer 3 may be provided with an engagement device on both sides to engage a headband (not shown in the figure), and the glasses may have a light weight effect.

Therefore, as mentioned above, after the creation of the lens, the edge of the lens is joined to the spacer frame to improve the better structural strength, assembly stability, and applicability of the multi-layer lens. The foregoing embodiment is an example of this creation, not a limitation of this creation. Equivalent changes made by this creative spirit should also fall within this creative category.
