A portable, collapsible air flow deflection apparatus detachably connectable to the roof of a motor vehicle for diverting air flow above and to the sides of the frontal surface of a vehicle in tow behind the motor vehicle. A pair of triangular, planar rigid panels are hinged along common edges and are relatively positioned at an angle thereabout to provide a V-shaped member. An internal planar frame cooperatively engages the hinged panels to fix the shape of the deflection member. Adjustable hold-down means secured to the frame compressively anchor the deflection member to the motor vehicle roof in an upright orientation, presenting a wedge-shaped deflection surface toward the front of the motor vehicle. Hinged and resilient portions along the lower edges of the deflection member adjust to the contour of the motor vehicle roof for presenting a continuous air deflection surface therewith. Wing-like extensions can be removably secured to the hinged panels to extend rearwardly therefrom for increasing the size of the air deflection pattern for use with towed vehicles having larger frontal surface areas.

Portable air flow deflector apparatus detachably connectable to the roof of a motor vehicle for reducing the air drag of a vehicle in tow by said motor vehicle by deflecting encountered air flow away from a forward surface of the towed vehicle, comprising: a. collapsible air deflection means mountable on said motor vehicle roof for deflecting air flow above and to the sides of said vehicle in tow, comprising: i. a first pair of like sized air deflecting panels each having a planar generally triangular surface for deflecting air flow; ii. first hinge means for connecting said pair of air deflectiNg panels along first corresponding edges thereof, defining a first hinge axis therealong; and iii. second hinge means connected along second corresponding edges of each of said pair of air deflecting panels for providing operative engagement of said second panel edges with said roof, said second hinge means providing variable angular engagement of said deflecting panels relative the general plane of said roof; b. a generally planar triangular frame oriented generally parallel to the general plane of said roof and cooperatively engaging said second hinge means and said pair of air deflecting panels along their said second edges, said pair of air deflecting panels cooperatively engaging said frame to define a fixed air deflection angle between said deflecting panels about said first hinge axis; and c. hold-down means operatively connected with said frame and with said air deflection means for securing said air deflection means to said roof under compressive pressure of said frame such that said first hinge axis obliquely diverges upward from the general plane of said roof and toward said towed vehicle.
