Abstract

An apparatus that provides an electronic image of areas around sides and rear of a large tractor trailer rig produced on a weatherproof screen that is located on the lower portion of the driver'"'"'s side mirror. One (1) camera would be located on the rear of the trailer in a center mounted position, while another camera would be located on a passenger side near the front of the vehicle so that it can see the entire side of the vehicle. The cameras would be equipped with fixed wide-angle lenses. The video signal from each camera would be routed to an automatic switcher that displays each signal for a pre-determined time or allows for the manual selection of either camera on a permanent basis. The video signal is then displayed on the weatherproof monitor portion of the side view mirror. In such a manner the truck driver can look at the mirror and the monitor in order to see all three (3) sides of the vehicle at once. This feature eliminates looking in various directions to check for obstructions while backing up or changing lanes.

Claims

1. A semi truck rig side mirror system for providing video images illustrating exterior areas of a semi truck rig, said semi truck rig side mirror system comprising:

first and second cameras capable of being attached to the semi truck rig;

a video display located at a lower portion of said side mirror assembly; and

,

a video switcher capable of being located within a cab portion of the semi truck rig;

wherein said video switcher automatically changes said video images between said cameras and thereby sequentially displays the exterior areas while viewing said side mirror assembly.

2. The semi truck rig side mirror system of claim 1, wherein each of said first and second cameras comprises:

a mount assembly capable of being attached to an exterior surface of the semi truck rig;

a body attached to said protective mount assembly; and

,

a lens attached to said body and capable of providing a 180-degree viewing angle along the exterior areas of the semi truck rig;

wherein said first and second cameras are spaced apart along the exterior surface of the semi truck rig.

3. The semi truck rig side mirror system of claim 1, wherein said side mirror assembly is capable of being mounted to an existing mirror mounting frame of the semi truck rig, said side mirror assembly comprising:

a mirror frame;

a mirrored glass portion attached to said mirror frame and located on an upper portion of said side mirror assembly; and

,

a protective glass cover attached to said mirror frame;

wherein glass cover covers said mirrored glass portion and said video display; and

,

wherein said video display illustrates said video image beneath said mirrored glass portion.

4. The semi truck rig side mirror system of claim 1, wherein said video display is located at the lower portion of said mirror assembly and positioned behind said protective glass cover and contained within said mirror frame.

5. The semi truck rig side mirror system of claim 1, further comprising:

an internal electric heating element located within said side mirror assembly; and

,

an automatic thermostatic switch electrically coupled to said internal electric heating element.

6. The semi truck rig side mirror system of claim 2, wherein said mount assembly comprises:

a U-shaped camera tilting bracket rotatably located therein.

7. The semi truck rig side mirror system of claim 1, wherein said video switcher comprises:

a switching speed potentiometer receiving said video images from each of said first and second cameras and thereafter displaying said video images for a pre-determined time.

8. The semi truck rig side mirror system of claim 7, wherein said video switcher further comprises:

a camera selector switch;

a plurality of input jacks connected to said camera selector switch;

a plurality of multiplexer circuits controlled by said camera selector switch; and

,

a plurality of video display drivers connected to said multiplexer circuits.

9. The semi truck rig side mirror system of claim 8, wherein said selector switch causes a sequential display of said video images on a timed basis, wherein the time interval of said sequential display is adjusted by said switching speed potentiometer.

10. A semi truck rig side mirror system for providing video images illustrating exterior areas of a semi truck rig, said semi truck rig side mirror system comprising:

first and second cameras capable of being attached to the semi truck rig, said first and second cameras facing rearwardly relative to a front end of the semi truck rig;

a side mirror assembly spaced from said first and second cameras and capable of being attached to the semi truck rig;

a video display located at a lower portion of said side mirror assembly; and

,

a video switcher capable of being located within a cab portion of the semi truck rig;

wherein said video switcher automatically changes said video images between said cameras and thereby sequentially displays the exterior areas while viewing said side mirror assembly.

11. The semi truck rig side mirror system of claim 10, wherein each of said first and second cameras comprises:

a mount assembly capable of being attached to an exterior surface of the semi truck rig;

a body attached to said protective mount assembly; and

,

a lens attached to said body and capable of providing a 180-degree viewing angle along the exterior areas of the semi truck rig;

wherein said first and second cameras are spaced apart along the exterior surface of the semi truck rig.

12. The semi truck rig side mirror system of claim 10, wherein said side mirror assembly is capable of being mounted to an existing mirror mounting frame of the semi truck rig, said side mirror assembly comprising:
