Abstract

The present invention's design provides a kind of sunglasses that can regulate any light and shade; the characteristics of this glasses are that lens materials adopts polarized lenses; several pieces are formed by stacking; control gear can make overlapping each sheet relatively rotate respectively; thereby change the light and shade of eyeglass; in using overall process, all can regulate, can adapt to various different light and shade requirements, extremely easy to use, and more help protection to eyes.

Description

Sun glasses capable of adjusting brightness

The invention relates to sunglasses which can be adjusted by a user at any time.

Currently known sunglasses: one is colored glass or plastic, the brightness of which is fixed, and the other is color-changing material, but the color-changing material has the disadvantages of slow color change, long response time and unsuitability for the requirements of users, and the color-changing material has high price and can not be adjusted freely.

The invention aims to provide sunglasses which are suitable for different users and can adjust the brightness at any time according to respective wishes.

The design of the invention is realized in such a way that each of the left and right lenses of a pair of glasses is formed by overlapping at least two polarized lenses, a distance can be reserved between the lenses, the left and right lenses can synchronously rotate by using a control mechanism, the upper and lower overlapped lenses are relatively rotated along the overlapped surface, if one lens rotates clockwise, the other opposite lenses rotate anticlockwise, and the overlapped lenses can be static, the other lenses rotate or can be all rotated. The properties of the polarizer, which can be briefly described as follows: when two sheets are overlapped and face the light to be completely transparent and brightest, a line is marked on the same positions of the two sheets, at the moment, the two lines are overlapped, the two lines are rotated relatively, the two lines are intersected to form an included angle, the larger the included angle is, the darker the lens is, when the included angle is 90 degrees, the lens becomes completely dark, and after the included angle is larger than 90 degrees, the lens gradually turns bright, so that the aim of randomly adjusting the brightness is fulfilled. This is a new application of polarization phenomena in the field of spectacles.

The design of the invention can actively adjust brightness in the whole using process, the response of the change is immediate, no time delay exists, the invention has the effects of convenient use, meeting the respective desire of each user to obtain the brightness, and improving the protection effect on eyes, and the latest polarizer material is not high in price, so the cost is lower.

The adjustable sunglasses designed according to the present invention may be implemented as follows:

example 1: FIG. 1 is a cross-sectional view of sun glasses with adjustable shade, which is adjusted by gears and rotated, cut along the superposed surface of the polarizer:

its main structure includes: the lens (1) is shown as a polaroid on one side of the section, the other side of the section is also provided with a similar polaroid and a frame gear (2), the lens is embedded in the polaroid, the left structure and the right structure are the same, a pinion (4) is centered and meshed with the left frame gear and the right frame gear, the spectacle frame (3) is provided, and a pinion shaft (5) extends out of the spectacle frame.

The rotating shaft (5) and the pinion (4) can drive the left and right frame gears and the polarized lens to synchronously rotate after moving, thereby achieving the purpose of adjusting brightness, and the rotation angle of the lens can be random.

Example 2: FIG. 2 is a cross-sectional view of adjustable-shade sunglasses adjusted for rotation by flexible connecting strips, taken along the coincident plane of the polarizers:

its main structure includes: lens (1), spectacle frame (3), circle shape frame (7) can be at the mirror holder internal rotation, and the lens inlays in circle shape frame, and the left and right sides structure is the same, and flexible connecting strip (6) flexible, nevertheless can not stretch out and draw back, and its both ends are fixed on circle shape frame, are equipped with the toggle structure of push-and-pull usefulness on flexible connecting strip or the circle shape frame.

The left and right circular frames (2) and the lens (1) can synchronously rotate by pushing or pulling the toggle structure through the connecting strip (6), so that the aim of adjusting the brightness is fulfilled, and the rotation angle of the lens can be more than 90 degrees and less than 150 degrees.

Claims

1. The adjustable light and shade sunglasses that the user can adjust at will at any time, its characteristic is:

a. the lens material is a polarizing lens.

b. Each lens is formed by laminating at least two polarizing plates, and a distance can be reserved between the plates.

c. The lens is rotated by a control mechanism to adjust the brightness.

2. The eyewear of claim 1 wherein the control mechanism causes at least one of the overlapping polarizers to rotate relative to the remaining lenses along the overlapping surface, the corresponding polarizers in the left and right lenses being in synchronized linkage.
