Abstract
Abstract A combined air foil and loading ramp for a pickup truck which includes a mounting bracket attached to the upper edge of a pickup truck tailgate with a rigid panel connected thereto for positioning in downwardly and forwardly inclined relation when the tailgate is in a vertical, closed position, positioned in overlying engagement with the upper surface of the tailgate or extending rearwardly from the upper edge of the tailgate in a generally horizontal position to form a loadbed extension when the tailgate is in a horizontal open position and extending downwardly and rearwardly in an inclined direction to form a loading ramp when the tailgate is in downwardly inclined relation to the loadbed of the pickup truck. The combined air foil and loading ramp converts the tailgate of a pickup truck to an air foil causing the air to flow over the closed tailgate for increasing the miles per gallon of gasoline consumed by the pickup truck engine, acts as a storage box for protecting tools or other items stored under the panel when the tailgate is closed, serves as an extension for the loadbed of the pickup when the tailgate is in a horizontal position and becomes an inclined loading ramp when the tailgate is positioned in the downwardly inclined position.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
118 words
A combined air foil and loading ramp for a pickup truck having a tailgate pivotally movable between a vertical, closed position and an open position comprising a bracket positioned on the upper edge of the tailgate, means securing the bracket to the tailgate for movement therewith, a rigid panel, means connecting the panel to the bracket for positioning the panel in a downwardly and forwardly inclined position with the free edge of the panel terminating adjacent the floor of a loadbed of a pickup truck to form an air foil when the tailgate is in vertical position, said panel forming an extension of the tailgate surface when the tailgate is in open position to form a loading ramp.
Claim 2
Dependent Claim
118 words
A combined air foil and loading ramp for a pickup truck having a tailgate pivotally movable between a vertical, closed position and an open position comprising a bracket positioned on the upper edge of the tailgate, means securing the bracket to the tailgate for movement therewith, a rigid panel, means connecting the panel to the bracket for positioning the panel in a downwardly and forwardly inclined position with the free edge of the panel terminating adjacent the floor of a loadbed of a pickup truck to form an air foil when the tailgate is in vertical position, said panel forming an extension of the tailgate surface when the tailgate is in open position to form a loading ramp.
Claim 3
Dependent Claim
59 words
The structure as defined in claim 1 wherein said means connecting the panel to the bracket includes a hinge structure enabling the panel to pivot from a downwardly and forwardly inclined position when the tailgate is in vertical, closed position to a position forming an extension of the loadbed and tailgate surface when the tailgate is in open position.
Claim 4
Dependent Claim
49 words
The structure as defined in claim 1 wherein said panel is constructed of two components, means telescopically adjustably connecting said components to enable the distance between the top edge of the tailgate to the free edge of the panel to be adjusted to fit pickup trucks having different dimensions.
Claim 5
Dependent Claim
69 words
The structure as defined in claim 1 wherein said bracket is of U-shaped configuration and includes parallel legs interconnected by a bight portion with the legs telescoped over the upper edge of the tailgate when in vertical position with the bight portion overlying the top edge of the tailgate to protect the tailgate from dents and protect the paint from being scratched along the top edge of the tailgate.
Claim 6
Dependent Claim
66 words
The structure as defined in claim 4 wherein the leg of said bracket engaged with the forward surface of the tailgate when the tailgate is in vertical position includes a downwardly and forwardly inclined groove and a vertical, upwardly opening groove receiving an edge of the panel with fastening devices clamping the panel rigidly in place and forming said means connecting the panel to the bracket.
Claim 7
Dependent Claim
55 words
The structure as defined in claim 1 wherein said panel includes a free edge having a resilient insert engaged with the floor of the loadbed to deflect air upwardly to form an air foil to reduce drag and increase gas mileage and also to produce downward force on the traction wheels of the pickup truck.
Claim 8
Dependent Claim
45 words
The structure as defined in claim 1 wherein said bracket is provided with a downwardly opening recess telescopically received over the upper edge of a tailgate, said means securing the bracket to the tailgate including fasteners extending through the bracket into engagement with the tailgate.
Claim 9
Dependent Claim
54 words
The structure as defined in claim 1 wherein said means connecting the panel to the bracket includes a downwardly inclined and downwardly opening groove receiving an edge of the panel and a second groove opening outwardly and upwardly in parallel relation to the tailgate for receiving the panel when in the extension forming position.
Claim 10
Dependent Claim
48 words
The structure as defined in claim 2 together with lock means releasably connecting the free edge of the panel to the floor of the loadbed to provide a lockable storage area enclosed by the floor, tailgate and rigid panel for storage of tools, tool box and the like.
