Description

Spectacle lens combination structure

This creation is about a combination structure of spectacle lenses, and mainly refers to a structure that can have better combination stability and convenient lens replacement.

Conventional glasses generally have frames, lenses, nose bridges, temples and other components. The lenses can have optical power, sun-shading or protection, and can have different colors to have a better wearing appearance. The frame is a full frame When the frame is in the shape of the lens, it has a sleeve hole that can fit the lens, and the lens can be set in the sleeve hole to be bundled by the sleeve hole; and when the frame is a half-frame type, an insert groove is provided, and the upper edge of the lens can be embedded The embedding groove is assembled on the frame, and after the lens and the frame are combined, a bolt combination can also be arranged.

However, although the lens is assembled with the frame by the fitting or embedding method, although it is easy to assemble, the combination stability is not good, which may cause the lens to be easily detached from the frame when wearing, and the bolt screw method can have better combination stability. But it must be screwed with tools, which is inconvenient to assemble and replace the lens.

The purpose of this creation is to provide a structure with better combination stability and convenient lens replacement.

This creation includes a frame, a lens, a nose bridge, and an assembly. The frame has a groove, and a buckle part is provided in the center of the upper part of the frame. The buckle part has a buckle edge; and the upper part of the lens can be It is embedded in the groove of the lens frame, and a concave portion that is recessed upward is provided below the center; the nose is set in the concave portion of the lens, and a pivot is provided behind the center; and the assembly has a pivoting portion below, There is a connecting piece in the center and a hook on the top. The pivot has a pivot hole that can fit the pivot of the nose bridge. The bottom of the connecting piece is connected with the pivot and the upper is connected with the hook. Portion connection; and the hook portion has an extension portion that extends toward the front, and the front of the extension portion has a hook portion that protrudes downward and can be buckled with the buckle edge of the buckle portion of the frame.

In one embodiment, the buckle edge of the mirror frame is located below the front side of the buckle part, and the upper back side of the buckle part has an arc edge.

In one embodiment, the pivot hole of the assembly has an opening whose width is slightly smaller than the diameter of the pivot.

When assembling this creation, the upper edge of the lens can be inserted into the groove of the frame, and the fitting groove of the nose bridge can be fitted into the concave part of the lens, and the pivot hole of the assembly can be fitted with the pivot, and the upper part of the assembly can be hooked. The part is moved forward and the hook part and the buckle edge position are hooked and positioned, and the upper and lower parts of the lens can be clamped by the frame and the nose bridge at the same time to have a better combination stability, and the lens will not fall off when being worn.

Please refer to Figure 1. This creation includes a mirror frame 1, a lens 2, a nose bridge 3, and an assembly 4. The mirror frame 1 is a half-frame body with an insert groove 11, and the insert groove 11 has two sides respectively. The buckle groove 111 is further provided with a buckle portion 12 in the upper center of the lens frame 1, the buckle portion 12 has an arc 121 on the upper back side, and a buckle edge 122 on the lower front side of the buckle portion 12.

The upper part of the lens 2 can be inserted into the embedding groove 11 of the frame 1, and an embedding edge 21 that can be inserted into the embedding groove 111 of the frame 1 is respectively provided on the upper two sides, and a concave portion 22 recessed upward is provided below the center. The recess 22 has a retaining edge 221 on both sides.

The nose bridge 3 is located at the recess 22 of the lens 2 and has a fitting groove 31 that can be engaged with the peripheral edge of the recess 22 of the lens 2, and a pivot 32 is provided behind the center.

The assembly 4 is made of a slightly flexible hard material. It has a pivotal portion 41 at the bottom, a connecting piece 42 in the center, and a hook portion 43 at the top. The pivotal portion 41 has a pivot that fits the nose bridge 3 The pivot hole 411 of the column 32, the pivot hole 411 has an opening 412 whose width is slightly smaller than the diameter of the pivot column 32; and the lower part of the connecting piece 42 is connected with the pivot part 41, and the upper part is connected with the hook part 43; and the hook part The portion 43 has an extension portion 431 extending forward, and the front of the extension portion 431 has a hook portion 432 that protrudes downward and can be buckled with the buckle edge 122 of the buckle portion 12 of the frame 1.

Please refer to Figures 1 to 4. The upper edge of the lens 2 can be inserted into the groove 11 of the frame 1, and the buckle edge 21 can be buckled and positioned with the buckle groove 111, and the fitting groove of the nose bridge 3 31 fits the position of the concave portion 22 of the lens 2, and the two sides of the nose bridge 3 can be positioned against the retaining edge 221.

Please refer to Figure 2, this creation allows the opening 412 of the pivot hole 411 of the assembly 4 to flexibly expand so that the pivot hole 411 can be fitted to the pivot post 32, and after fitting, the width of the opening 412 is flexibly restored so that the pivot hole 411 does not Will be separated from the pivot 32, and as shown in Figure 3, the upper hook portion 43 of the assembly 4 is moved forward and the hook portion 432 can be easily moved to the position of the front buckle edge 122 along the arc 121 of the buckle portion 12 of the frame 1 The buckle edge 122 is positioned so that the upper and lower sides of the lens 2 can be clamped by the frame 1 and the nose bridge 3 at the same time to have a better combination stability, and it can ensure that the lens 2 will not fall off when worn.

In this creation, when the lens 2 is to be replaced, the hook portion 43 of the assembly 4 can be separated from the buckle portion 12 of the frame 1, then the frame 1 and the nose bridge 3 can be quickly taken out, and another lens 2 can be quickly assembled. Convenient function.

Based on the above, this creation can have better combination stability and easy to replace lens effects, and the frame of this creation can also be a full-frame type, and the foregoing embodiments are examples of creation, not the limitation of this creation. The equivalent changes made by this creative spirit should also fall within the scope of this creative.
