And the film can reflex the rear scene into the eyes.

Description

Sandwich type colcur reflector

The utility model is a kind ofly can see that the place ahead can see the tinted glasses (sunglasses) of inclined to one side rear scenery again.

Principle of the present utility model is: be provided with interlayer in lens, reflex reflector (reflective metal film) is arranged in the interlayer, this device can reflex to the scenery at inclined to one side rear in the eye.

The utility model is the reflective glasses continue my the another kind application after application on April 23rd, 87 " No. 24238 reflective glasses of 87206862.5 utility models ".The former is not attractive in appearance outside because of plated film, is out of favour this person then improve to some extent (plated film is in interlayer).

The purpose of this utility model makes the person of wearing can see that the place ahead can see inclined to one side rear again exactly, and is similar with general tinted glasses again in appearance.

Structure of the present utility model and method for making are as follows:

Shape of the present utility model, is made up of eyeglass A and mirror holder B as Fig. 1 with general tinted glasses.

The front view (FV) of its eyeglass such as Fig. 2 (with about two eyeglasses represent).Every eyeglass is by inside and outside two-layer synthetic, and its reflex reflector is just in this in interlayer between outer lens, and as Fig. 3 (respectively with about two eyeglasses represent), b is an outboard profile, 1. is outer eyeglass, 2. is the internal layer eyeglass, 3. is reflex reflector (reflective metal film); A is a front perspective view,

Be the eyeglass main part, transparent (can see through the light identical) with this colour of lens, in order to watching the place ahead scenery,

For having the reflex reflector part in the eyeglass interlayer, in order to watch inclined to one side rear scenery (this place area account for eyeglass area 1/5).(code name among its each figure logical)

Outer eyeglass is the colored transparent glass mirror, and its thickness is 1.2 ± 0.3 millimeters.The internal layer eyeglass is coloured (or colourless) clear glass eyeglass, and its shape, size and thickness have its difference only with outer eyeglass, is (to be equivalent to Fig. 3 a's by ear one side The place) thin slightly 0.01-0.1 millimeter, as Fig. 4 it

Place's (outboard profile, represent with the single eyeglass in right side), plate one deck reflective metal film (reflex reflector) on herein, this film plays reflective mirror, the scenery at inclined to one side rear can be reflexed in the eye, if outer eyeglass is light, then on this film, coat skim colored paint (without white paint) again, as Fig. 5 (outboard profile), in case locate forwards reflective here, make not too obvious in appearance herein Within be the forward and backward figure of the amplification at this place, 3. be reflective metal film, 4. be the thin layer colored paint, (more than, the internal layer eyeglass it

The place compare the eyeglass elsewhere thin go part, reflective metal film 3., the thin layer colored paint 4., their thickness on figure all greater than ratio in kind),, outer eyeglass need not be coated with this lacquer (can to block a part reflective because of deep-color lens) if being dark, but after this operation, all must make whole internal layer eyeglass with thick, through reconditioning interior outer lens is overlapped again, sticking again limit (with interior outer lens edge sealing stick together), mix mirror holder again.

Reflected light path of the present utility model such as Fig. 6 (with about two eyeglasses represent), p is an incident ray, q is an emergent ray.

The visual field of the present utility model is 160 ° ± 5 ° (because of the eyeglass size has discrepancy slightly), as Fig. 7,5. for the place ahead common vision area of two orders is 100 °, for independent one visual district, inclined to one side rear is 30 ° * 2, is non-vision area 7., 8. 6., 7. is 100 °, 8. is 50 ° * 2.

Outer eyeglass of the present utility model is advisable with color depth, can make like this

Be in not too obvious in appearance.The colour saturation of internal layer eyeglass with have or not, determining vision area bright-dark degree 6., but this Qu Taiming (surpass 5. district) is not suitable for also, otherwise can makes vision confusing.

Other structures of the present utility model are with general tinted glasses.

Claims

A kind ofly can see that the place ahead can see the tinted glasses of inclined to one side rear scenery again, it is characterized in that in the eyeglass of this mirror interlayer being arranged, reflective metal film is housed in the interlayer, this film can reflex to the scenery at inclined to one side rear in the eye.
