Abstract

A rear view mirror for mounting on the windshield of a motor vehicle which mirror provides a one position, relatively continuous, panoramic rear view without significant distortion of distance perspective, which mirror comprises a central flat surface mirror and two side or wing mirrors having a flat surface but a convexly curved surface toward the exterior peripheral horizontal edge area thereof and vertically hinged in line with the vertical plane of the central mirror on the interior edge to provide a substantially continuous reflecting rear view, the side or wing mirrors adjustably hinged at the rear and an extension lever to provide for the horizontal adjustment of the mirrors about a horizontal axis, the mirror and the motor vehicle having a windshield which includes the rear view panoramic mirror.

Claims

1. A panoramic rear-view mirror adapted to be mounted on the windshield of a motor vehicle, which mirror provides a one position, relatively continuous, panoramic rear view without distortion of distance perspective, while at the same time keeping the forward view of the highway within peripheral vision, which mirror comprises in combination:

(a) mirror housing means which comprises a first and a second wing mirror casing;

(b) a flat reflecting surface mirror centered between the first and second side mirror casings;

(c) a first reflecting mirror disposed in the first wing casing and a second reflecting mirror disposed in the second wing casing, the first and second mirrors in the same vertical plane as the center mirror, and the adjacent mirror edges closely adjacent to the respective edges of the central mirror to provide a substantially continuous reflecting mirror view;

(d) the first and second mirrors having a flat surface reflecting area and a convexly curved mirror surface area at the exterior peripheral edge, the flat surface occupying a substantial area portion of said mirror to provide minimal distortion of distance perspective;

(e) first adjustment means to secure the first and second casings to the central mirror and to move the first and second casings about a vertical axis with respect to the central mirror;

(f) second adjustment means to move the first and second mirrors within the respective casings about a horizontal axis within the respective casings; and

(g) means to connect at a defined distance the central mirror to the motor vehicle.

2. The mirror of claim 1 wherein the means to secure the first and second casings to the central mirror comprises top and bottom strong friction hinge pins secured through the first and second casings to the top and bottom, respectively, of the mirror.

3. The mirror of claim 1 wherein the means to move the first and second mirrors comprises a strong friction hinge secured to the back of the first and second mirrors and an extension lever to permit manual movement of the first and second mirrors about the horizontal hinge axis.

4. The mirror of claim 1 wherein the peripheral convexly curved area extends a distance of about one inch, or less, from the flat surface central area to the exterior mirror edge.

5. The mirror of claim 1 wherein the maximum separation between the edge of the wing mirrors and the center mirror is about one millimeter or less.

6. The mirror of claim 1 wherein the means to connect comprises a telescoping arm secured at the one end to the back of the central mirror and adapted to be secured at the other end to the windshield.

7. A motor vehicle having a windshield and which includes a rear-view mirror of claim 1 secured to the windshield.

8. A motor vehicle having a windshield and which includes a rear-view mirror of claim 1 wherein the means to connect comprises a telescoping arm secured at the one end to the back of the central mirror and adapted to be secured at the other end to the windshield.

9. A panoramic, rear-view mirror adapted to be mounted on the windshield of a motor vehicle, which mirror provides a one position, relatively continuous, panoramic rear view without distortion of distance perspective, while at the same time keeping the forward view of the highway within peripheral vision, which mirrors comprises in combination:

(a) mirror housing means which comprises a first and a second wing mirror casing;

(b) a flat reflecting surface mirror centered between the first and second side mirror casings;

(c) a first reflecting mirror disposed in the first wing casing and a second reflecting mirror disposed in the second wing casing, the first and second mirrors in the same vertical plane as the center mirror, and the adjacent mirror edges closely adjacent to the respective edges of the central mirror to provide a substantially continuous reflecting mirror view;

(d) the first and second mirror having a flat surface reflecting area and a gently convexly curved mirror surface area at the exterior peripheral edge which convexed mirror surface area extends a distance of about one inch or less from the flat surface area.

(e) first adjustment means to secure the first and second casings to the central mirror and to move the first and second casings about a vertical axis with respect to the central mirror;

(f) second adjustment means to move the first and second mirror within the respective casings about a horizontal axis within the respective casings; and

(g) means to connect at a defined distance the central mirror to the windshield of a motor vehicle which means comprises a telescoping arm secured at the one end to the back of the central mirror and adapted to be secured at the other end to the windshield.

10. A motor vehicle having a windshield and which includes a rear-view mirror of claim 9.
