Description

Attached lens assembly for optical glasses

Technical Field

The present invention relates to an accessory lens assembly for optical glasses, particularly in relation to the structure of the accessory lens.

Background

In general, in order to shield a person with myopia, hyperopia, or other visual impairment from glare and to avoid irritation to the eyes, an auxiliary lens is disposed on an optical eyeglass (main lens) for correction, and the auxiliary lens is generally a sunglass lens. In the prior art, the structure of the attached glasses is various, and the combined positioning mode of the attached glasses and the optical glasses is also various. Among them, the auxiliary glasses fixedly clamped on the optical glasses by the butterfly clip are most widely used. However, the butterfly clip type of attachment also presents some problems in use.

First, the accessory mirror lens on the market is mostly two formula, and two lenses are connected to the centre need additionally erect a well roof beam, perhaps joins in marriage a picture frame again and assembles two lenses together, has increased the cost.

Secondly, accessories attached with the glasses on the market are made to be rough, flat, free of stereoscopic impression and not attractive enough.

And thirdly, most of accessories on the market and the butterfly clamp are matched by a cylindrical clamping groove and a rolling shaft, the auxiliary mirror lens is positioned by means of tight fit when being upwards lifted, the clamping groove and the rolling shaft are matched too tightly and are not easy to lift, the clamping groove and the rolling shaft are matched too loosely and are not easy to clamp, and the auxiliary mirror lens can slide down and is difficult to position when being lifted.

And fourthly, clip leg foot covers on the market are all cylindrical foot covers, the stress area is small, and the lens is easy to shake.

Based on the above problem, the inventor has redesigned a utility model attaches mirror subassembly to be applicable to optical glasses, convenient equipment, reduce cost can multi-angle location when upwards lifting, and the installation location is easy during the use, and the lens does not rock.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 12, an auxiliary lens assembly for optical glasses according to the present invention includes a lens 10, an accessory 20 and a butterfly clip 30.

The lens 10 is a piece type goggles, the middle of the lens 10 is directly cut to form a middle beam 11, namely the middle beam 11 is arranged, and the structure is simple. Specifically, the polarizer may be designed and cut into a piece of goggles, and the lens 10 is used as the main body of the auxiliary lens assembly. The one-piece goggles can be cut into various shapes and have various colors, can be dyed and coated, can also be used for laser patterns such as eyebrows and the like, or realize the functions of more lenses, and has the advantages of flexible and convenient use, various colors and random wearing and putting.

The best design of the accessory 20 is reverse trapezoid, the accessory 20 is used as a key component of the auxiliary glasses and is erected between the auxiliary glasses lens 10 and the butterfly clip 30, the appearance is attractive, the shape is similar to the nose bridge, and the lens looks three-dimensional and attractive and elegant. The back of the fitting 20 is provided with a lens slot 21, the lens slot 21 having an upper groove 22, a lower groove 23 and a slot bottom 24. The bridge 11 of the lens 10 is placed in the lens groove 21 of the fitting 20, and the upper groove 22 and the lower groove 23 are respectively clamped on the upper and lower sides of the bridge 11 of the lens 10, so that the lens 10 is assembled with the fitting 20. Therefore, the lens 10 is convenient to assemble, the material cost of an additionally erected middle beam and the material cost of the lens frame are saved, the cost of the attached glasses is reduced, and the price is superior. In order to assemble fixedly better, the utility model discloses the preferred design is lens groove 21 tank bottom 24 of accessory 20 designs for shallow curved surface spill for firmly block the well roof beam 11 of lens 10, prevent that lens 10 from rocking, lens 10 is difficult to separate with accessory 20, guarantees to attach mirror normal use. Further, the utility model discloses a preferred design is the lower slot 23 of accessory 20 lens groove 21 sets to the crescent of falling, is identical with the well roof beam 11 radian of lens 10, can block the well roof beam 11 of lens 10 better, prevents that lens 10 from rocking.

The top of the lens slot 21 of the fitting 20 is provided with a projection 25 at the back, the projection 25 is provided with a roller slot 26, and a roller 31 at the upper end of the butterfly clip 30 is inserted into the roller slot 26, so that the butterfly clip 30 is assembled with the fitting 20. The utility model discloses an optimal design is: the roller slot 26 cross-section of the lug 25 of the accessory 20 is rhombus, correspondingly, the roller 31 cross-section of the butterfly clip 30 is also rhombus, a plurality of clamping points (specifically, four clamping points can be provided) are arranged on the surfaces of the inner wall of the rhombus roller slot 26 and the rhombus roller 31, three clamping pits 27 are formed in the rhombus roller slot 26, and four convex strips 311 are formed on the surface of the rhombus roller 31, so that when the auxiliary glasses are worn in daily life, the lifting height of the auxiliary glasses can be adjusted as required when the auxiliary glasses are not used or need to be lifted, compared with the traditional cylindrical roller and the clamping slots, the lifting height of the auxiliary glasses can be better fixedly kept.

The butterfly clip 30 of the present invention may be in the form shown in the drawings, but is not limited to the structure shown in the drawings, and includes a front clip portion 32 and a rear clip portion 33.
