Claim 1
Independent Claim
210 words
A wind deflector for a vehicle pulling a trailer, comprising: a support frame including spaced runners each having a respective forward and rear end, an elongated bendable flat deflector member having a respective trailing and leading edge, means for securing the respective opposite ends of said leading edge of said deflector member to the respective forward ends of said runners so that said leading edge extends between the forward ends of said runners in contact with the roof of the vehicle and said deflector member extends upwardly and rearwardly therefrom to said trailing edge. support means on the rear ends of said runners operatively connected to the trailing edge of said deflector member, and means for removably securing said support frame to the roof of a vehicle so that the forward ends of said runners are in close proximity to the vehicle windshield and said runners are in abutting contact with the surface of the vehicle roof and with said means acting to hold and maintain the leading edge of said deflector member in abutting contact with the vehicle roof whereby air is deflected only upwardly to pass over the vehicle and trailer and is prevented from passing beneath said deflector member to thereby reduce the air content rearwardly thereof.

Claim 3
Dependent Claim
93 words
A wind deflector as defined in claim 1 including: means for pivotally securing the respective opposite ends of said leading edge to the forwards ends of said runners, said support means comprising, a respective upstanding rigid support arm secured at its lower end to the respective rear ends of said runners, and means for selectively removably securing the respective opposite ends of said trailing edge to selected longitudinal points on said upstanding support arms whereby the angle of inclination of said wind deflector relative to the roof of the vehicle can be varied.
Claim 4
Dependent Claim

A wind deflector as defined in claim 2 including: means for pivotally securing said respective upstanding support arms to said runners whereby upon detachment of said trailing edge from said support arms, said arms and said wind deflector are movable to a folded position in substantial parallel and juxtaposition with each other and with said runners, and means for releasably securing said support arms and said wind deflector to said runners when in folded position.
Claim 5
Dependent Claim
28 words
A wind deflector as defined in claim 1 including a protective covering on that part of said support frame being in contact with the roof of the vehicle.
Claim 6
Dependent Claim
43 words
A wind deflector as defined in claim 1 including: said deflector being of transparent material, rigid mounting strips secured to respective side edges of said deflector, a stiffener member secured to said trailing edge, and a protective covering secured to said leading edge.
Claim 7
Dependent Claim
39 words
A wind deflector as defined in claim 1 including: a rigid member connecting the rear ends of said runners to define a closed rear end of said frame support, and the front end of said frame support being open.
