Abstract

A tailgate construction for pickup trucks and other vehicles which permits the passage of air therethrough to reduce the drag on the vehicle associated with the tailgate construction when the vehicle is in use and thus increase the gas mileage of the vehicle. Also disclosed is a shutter mechanism for selectively preventing the passage of air through the tailgate construction.

Claims

1. A low air drag tailgate construction adapted to be pivotally mounted in the tailgate opening between the truck sidewalls at the trailing end of the open top cargo compartment of a pickup truck on the tailgate mounting brackets provided on the pickup truck in replacement of the conventional tailgate normally associated therewith, said tailgate construction comprising:

an open frame having a peripheral configuration corresponding generally to the configuration of the tailgate opening to the open top cargo compartment of the pickup truck, said open frame pivotally connected to the trailing end of the pickup truck in lieu of the conventional tailgate for selectively extending around the tailgate opening at the trailing end of the open top cargo compartment, said open frame comprising a pair of spaced apart, parallel generally vertically extending end plates having upper and lower ends;

an upper, generally horizontal, tubular edge member extending between and connected to the upper ends of said end plates;

a lower, generally horizontal, tubular edge member extending between and connected to said end plates adjacent the lower ends thereof;

at least one generally vertically extending tubular brace member extending between and connected to said upper and lower tubular edge members intermediate their ends; and

a pair of pivot connectors attached to the lower ends of said end plates below said lower tubular edge member and coaxially aligned along a common tailgate pivot axis generally parallel to said upper and lower tubular edge members, said pivot connectors adapted to pivotally connect said open frame to the tailgate mounting brackets on the pickup truck so that said open frame can be pivoted upwardly to a closed position whereby said end plates extend along opposite sides of the tailgate opening, said upper tubular edge member extends along the upper edge of the tailgate opening, and said lower tubular edge member extends along the lower edge of the tailgate opening, said open frame defining opening therethrough between said end plates, said upper and lower tubular edge members, and said brace member; and

an expanded metal screen cover member covering the openings through said open frame and attached to that side of said open frame facing the truck cargo compartment along said end plates, and said upper and lower edge members for retaining cargo in the cargo space, said expanded metal screen cover member defining a plurality of small air passages therethrough so that the size of any one of said air passages is sufficiently small to retain cargo in the cargo compartment yet at least seventy-five percent of the cover member area is open through said air passages to permit air to flow therethrough to reduce the air drag associated therewith, said expanded metal screen cover member constructed and arranged so that it is strong in a direction normal to the plane of said cover member to prevent bending of said cover member when engaged by cargo in the cargo compartment and to reinforce said open frame.

2. The low air drag tailgate construction of claim 1 further including a pair of catch assemblies mounted on said end plates constructed and arranged to selectively hold said open frame in its closed position.

3. The low air drag tailgate construction of claim 2 further including locating means for limiting the pivotal movement of said open frame from its closed position to an open position where said open frame lies in a generally horizontal plane.

4. The low air drag tailgate construction of claim 3 wherein said end plates have a peripheral contour matching the contour of the side walls of the cargo compartment and said end plates are in registration with the side walls at the tailgate opening when said open frame is in its closed position.
