| Abstract: |
An air current deflecting device for use with a vehicle pulling a trailer or the like. An elongated transparent deflecting shield is pivotally secured to a pair of spaced-apart support members which are detachably secured to the vehicle so as to position the deflecting shield above the roof of the vehicle. The shield includes a face portion having a length approximately equal to the width of the vehicle roof and having wing portions at opposite ends thereof which extend downwardly and rearwardly therefrom. The shield is selectively movable from a position wherein the leading edge of the face portion is positioned below and forwardly of the trailing edge of the face portion so that the inclined face portion will deflect air currents passing over the vehicle roof upwardly and rearwardly above the forward end of the trailer. The lower or leading edge of the shield is positioned above the vehicle roof to permit a certain amount of air to pass therebelow to eliminate the formation of a vacuum pocket rearwardly of the shield means. The shield may also be selectively pivoted to an inoperative position wherein the face portion of the shield is substantially parallel to the roof of the vehicle.

I claim:
1. An air current deflecting device for a vehicle pulling a trailer, comprising,
- a support means adapted to be detachably secured to the vehicle roof,
- and an elongated deflecting shield means mounted on said support means spaced above the roof of said vehicle, said shield means having its longitudinal axis transverse to the direction of travel of said vehicle and having a face portion with leading and trailing edges, said trailing edge normally being positioned above and rearwardly of said leading edge so that said face portion deflects the air passing over the roof of said trailer,
- said support means being comprised of first and second support members detachably secured to said vehicle at opposite sides of the roof thereof, each of said support members including first and second resilient suction cup members mounted on the roof and having a bar secured thereto and extending therebetween,
- an upstanding post means secured to said bar and extending upwardly therefrom,
- said shield means being pivotally secured to the upstanding post means on said first and second support members inwardly of the outer ends of said shield means.
