Abstract
Although the angle of sideward and backward directions to be confirmed through rearview mirrors by a driver while driving a car is about 60°, the angle at which other cars running side by side reach the back doors of the said car, existing rearview mirrors allow only 45°, keeping drivers from seeing sideward space (so-called dead space). This invention has solved above shortcomings by Outside and Inside Rearview Mirror for cars, using the system of encasing a convex curve mirror that covers a wide angle so as to see sideward space to be confirmed in the rearview Mirror box, and setting a convex lens with magnification and curvature fitted to the curve mirror so as to magnify reduced images of cars on the convex curve mirror as much as the size on existing rearview mirrors, and pick up a wide range of images on the curve mirror, in front of the same mirror.
Description
DESCRIPTION
Outside and Inside Rearview Mirror for cars that have removed dead space through a convex lens and a convex curve mirror.
Technical Field
An invention in the technical field of optics, complementing short¬ comings of existing rearview mirrors through a convex curve mirror that covers wide view in compensation for reduced images of objects, and a convex lense that magnifies images of everything.
Background Art Any driver in a car equipped with existing rearview mirrors cannot see sideward objects to be confirmed without fail, because his/her side¬ ward and backward view through rearview mirrors is limited to an angle of 45°. (so-called dead space).
Auxiliary rearview mirrors, circular or rectangular convex curve mirrors introduced to supplement the said shortcomings, have enabled dri¬ vers to see sideward objects, but have completely kept them from measur¬ ing the distance to the objects, because images of cars on the side and in the rear were reduced to - as a result of being convex curve mirr¬ ors.
Disclosure of Invention
This invention has settled the foregoing problems by allowing drive¬ rs a wide field of view to the side and the rear that requires the most careful confirmation possible. Rearview Mirror on the side of driver's seat : This is composed of a convex curve mirror with curvature of 1,060mm
R encased in a Rearview Mirror box, and a convex lens, made of blue glass or F.R.P., cut out from a circular convex lens 22cm in diameter with curvature of -176mm R inside and + 132mm R outside according to the size of a Rearview Mirror box 18cm in width, 12cm in right length and 11 cm in left length, and set in front of the curve mirror. Rearview Mirror on the side of assistant driver's seat :
This is composed of a convex curve mirror with curvature of l,060ιmrι R encased in a Rearview Mirror box, and a convex lens, made of blue gla¬ ss or F.R.P., cut out from a circular convex lens 22cm in diameter with curvature of -176mm R inside and + 151mm R outside, according to the size of a Rearview Mirror box 18cm in width, 12cm in left length and 11 cm in right length, and set in front of the curve mirror. Inside Reaview Mirror :
This is composed of a convex curve mirror with curvature of 1,060mm R encased in a Rearview Mirror box, and a convex lens, made of blue glass or F.R.P., cut out from a circular convex lens 22 cm in diameter with curvature of -176mm R inside and + 132mm R outside, according to the size of a Rearview Mirror box 20cm in width and 6cm in length, and set in front of the curve mirror.
Both the Outside and Inside Rearview Mirror are made with the encas¬ ed convex curve mirror integrated with the convex lens set in front of the curve mirror in a frame, which is fixed in the Rearview Mirror box. In case of using a F.R.P. convex lens, its surface is proctected with a glass cover with same curvature as that of the outside of the convex lens.
There are some reasons for setting the convex lens in front of the convex curve mirror as aforesaid.
Supposing that a convex lens is only to magnify reduced images of objects to their original size, it will suffice to set a convex lens the
size of a Rearview Mirror box with curvature of -1,060mm R inside corre¬ sponding to that of a convex mirror and + 353mm R outside in front of the convex mirror with curvature of 1,060mm R encased in a Rearview Mirror box. But the convex lens so set can show, in the course of magn- ifying all the images picked up by the encased convex curve mirror, merely 55% of them around the conter of the curve mirror, ending in eff¬ ect similar to a plane mirror of same size.
Therefore in order to secure a range desired by drivers and see images within the sucured range magnified as much as ones on existing rearview mirrors, a convex lens, cut out to be 22cm in diameter and according to the size of a Rearview Mirror box, with curvature corresponding to that of an encased convex curve mirror, should be modified to be more curved inside and more raised outside corresponding to the increase of curvatu¬ re inside. To explain in detail, every time the curvature of a convex lens is changed to widen the gap between the center of the inside of the lens and the surface of an encased convex curve mirror by 1mm from the initi¬ al state in which the rims of both the convex curve mirror with curvatu¬ re of 1,060mm R encased in a Rearview Mirror box and a convex lens, cut out to be 22cm in diameter and according to the size of a Rearview Mirror box, set in front of the curve mirror, are made to contact closely each other, the convex lens shows a wider range of images picked up by the curve mirror by 1°. Inspired by the foregoing phenomenon of the convex lens, this Rearview Mirror is made with the inside curvature of the con- vex lens modified from -1,060mm R to -176mm R, the outside curvature of the same lens done from + 353mm R to + 132mm R in case of Rearview Mirr¬ or on the side of driver's seat, and to + 151mm R in case of Rearview Mirror on the side of assistant driver's seat so as to leave spaces of 17mm between the centers of both the encased convex curve mirror and the
convex lens set in front of the curve mirror.
It improves, without changing magnification, the range of images picked up by the encased convex curve mirror by about 17°. While the range drivers can confirm through existing rearview mirroesis about 45°, this device provides drivers with a range of some 60°, that is 70% of the whole size of the encased curve mirror around its center, allowing dirvers to see cars of same direction reach back doors of a test car, and in case of Inside Rearview Mirror, 2/3 of the backs of both front seats. However, convex lenses of both Outside and Inside Rearview Mirror form another small and vague images of cars on the side and in the rear due to the thickness of lenses,causing headlights of cars in the rear to look double at night. To remove these demerits, the convex curve mirror is encased in Rearview Mirror box slantingly with its lower part popped out by 1cm compared with its upper part, and the convex lens is set vertically in front of the curve mirror.
