Abstract
Abstract A blind side mirror system and apparatus including a fixed mirror and a rotating mirror so combined and operable to provide blind side viewing when backing or turning a semi-trailer. A belt drive is employed to pivot the rotating mirror according as the cab is turned. The mirror system is adjustable, and positioned and controlled from the cab, and can be positioned for view of the blind side when backing and turning in either direction. The mirrors can be rotated to a position where there will be minimum interference when not required. The mirrors are mounted in such a manner as to utilize normal rear view mirrors or direct viewing by the driver.

Claim 1
Independent Claim
201 words
A blind side mirror system for combination vehicles such as semi-trailers, including a tractor and a trailer comprising: A. a revolvable support having a vertical axis of rotation fixedly positioned outboard of the longitudinal sides of said trailer; B. means for selectively controllably revolving said support independently of said tractor and trailer and the angular relationship therebetween; C. a fixed mirror mounted on said revolvable support in a fixed position thereon, and movable in a fixed circle with and upon revolving said support; D. a rotatable mirror rotatably mounted in a fixed position on said revolvable support and movable with and upon said support in said fixed circle upon revolving said support, and; E. drive means interconnecting said support revolving means and said rotatable mirror for angularly rotating said rotatable mirror about the axis thereof on and with respect to said revolvable support and with respect to said fixed mirror thereon simultaneous with revolution of said support in a coupled controlled synchronized angular position adjustment of said rotatable mirror with respect to said fixed mirror to correlate and adjust the lines of sight between said mirrors for unobstructed rear viewing along the trailer sides and behind the trailer from the tractor.

A blind side mirror system for combination vehicles such as semi-trailers, including a tractor and a trailer comprising: A. a revolvable support having a vertical axis of rotation fixedly positioned outboard of the longitudinal sides of said trailer; B. means for selectively controllably revolving said support independently of said tractor and trailer and the angular relationship therebetween; C. a fixed mirror mounted on said revolvable support in a fixed position thereon, and movable in a fixed circle with and upon revolving said support; D. a rotatable mirror rotatably mounted in a fixed position on said revolvable support and movable with and upon said support in said fixed circle upon revolving said support, and; E. drive means interconnecting said support revolving means and said rotatable mirror for angularly rotating said rotatable mirror about the axis thereof on and with respect to said revolvable support and with respect to said fixed mirror thereon simultaneous with revolution of said support in a coupled controlled synchronized angular position adjustment of said rotatable mirror with respect to said fixed mirror to correlate and adjust the lines of sight between said mirrors for unobstructed rear viewing along the trailer sides and behind the trailer from the tractor.
Claim 3
Dependent Claim
71 words
A mirror system as claimed in claim 1, including bracket means attachable with respect to said trailer, a controllable electric motor mounted on said bracket and having an output shaft extending therethrough, said support means including an upper support pivotally mounted in said bracket and a lower support attached tO said output shaft of said motor, said motor upon actuation simultaneously and conjointly revolving said supports and the mirrors mounted thereon.
Claim 4
Dependent Claim
72 words
A mirror system as claimed in claim 2, said fixed mirror being interconnected and fixed between said upper and lower supports, upper and lower pivots mounting said rotating mirror between said upper and lower supports, a pulley attached to said mounting bracket, a pulley attached to said rotating mirror lower pivot, and interconnecting drive means between said pulleys operable for compensating rotation of said rotating mirror upon rotation of said support means.
Claim 5
Dependent Claim
22 words
A mirror system as claimed in claim 3, wherein a twisted belt drive interconnects said pulleys for rotation of said rotating mirror.
Claim 6
Dependent Claim
63 words
A mirror system as claimed in claim 3, wherein the drive means for the rotating mirror includes an idler gear attached to said mounting bracket, a first gear attached to said mounting bracket in operative association with said idler gear, and a second gear attached to said rotating mirror pivot operatively engaged with said idler gear for operable rotation of said rotating mirror.
Claim 7
Dependent Claim
46 words
A mirror system as claimed in claim 3, wherein the cab of said tractor includes a rear view mirror, said mirror system being so mounted as to permit use in conjunction with said rear view mirror, or direct viewing by a vehicle operator in said cab.
