Abstract
Abstract Truck air foils, more particularly air foils which serve to deflect or direct air flow normally impinging on the front of a truck or a trailer box in such a manner as to decrease wind resistance thereagainst, the air foils being adjustable to accommodate, for different sizes and configuration of trucks, tractors and trailers, and for adjustably varying the flow angle and direction of the air. The air foils can be moved to retracted storage positions to facilitate shipping, such as folded flat against a trailer box, or stored in recesses in the roof or wall thereof, and when mounted in operative air deflecting positions, do not interfere with the visibility of standard top running lights of the vehicle.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
206 words
A truck air foil mounted on the front surface of a box thereof, and the like, comprising: A. a generally triangular shaped air foil including: i. a substantially rectangularly shaped solid top portion; ii. a substantially rectangularly shaped solid bottom portion; and iii. means hingedly and adjustably interconnecting said top and bottom portions; B. a mounting means for said air foil including: i. means connecting said air foil to said box by attaching a hinge to said box and to said substantially rectangularly shaped top portion on its free edge opposite the edge hingedly and adjustably interconnecting said top and bottom portions; and, ii. a plurality of parrallel vertically spaced positioning brackets on said surface of said box hingedly and adjustably connecting the substantially rectangularly shaped bottom portion to said box by engaging the free edge of said bottom portion opposite the edge hingedly and adjustably interconnecting said top and bottom portions, whereby the angular configuration and position of said air foil can be adjustably varied by selectively connecting said free edge of said bottom portion to different positioning brackets on said box, and whereby said airfoils are capable of movement to a stored inoperative position with respect to said box to minimize overall box dimentions.
Claim 2
Dependent Claim
206 words
A truck air foil mounted on the front surface of a box thereof, and the like, comprising: A. a generally triangular shaped air foil including: i. a substantially rectangularly shaped solid top portion; ii. a substantially rectangularly shaped solid bottom portion; and iii. means hingedly and adjustably interconnecting said top and bottom portions; B. a mounting means for said air foil including: i. means connecting said air foil to said box by attaching a hinge to said box and to said substantially rectangularly shaped top portion on its free edge opposite the edge hingedly and adjustably interconnecting said top and bottom portions; and, ii. a plurality of parrallel vertically spaced positioning brackets on said surface of said box hingedly and adjustably connecting the substantially rectangularly shaped bottom portion to said box by engaging the free edge of said bottom portion opposite the edge hingedly and adjustably interconnecting said top and bottom portions, whereby the angular configuration and position of said air foil can be adjustably varied by selectively connecting said free edge of said bottom portion to different positioning brackets on said box, and whereby said airfoils are capable of movement to a stored inoperative position with respect to said box to minimize overall box dimentions.
Claim 3
Dependent Claim
23 words
A truck air foil as claimed in claim 1 wherein said air foil is horizontally mounted on the front surface of a box.
Claim 4
Dependent Claim
39 words
A truck air foil as claimed in claim 2 and including generally triangularly shaped air foils vertically positioned on the front surface of a box proximate the side edges of the box and beneath the horizontally mounted air foil.
Claim 5
Dependent Claim
25 words
A truck air foil as claimed in claim 3 wherein said vertical air foils are mounted adjustably for varying the angular configuration and position thereof.
Claim 6
Dependent Claim
29 words
A truck air foil as claimed in claim 2 including a tractor, trailer combination, said air foil being mounted on the front surface of the box of said trailer.
Claim 7
Dependent Claim
39 words

Claim 8
Dependent Claim
204 words
A truck air foil mounted on the front surface of a box thereof, and the like, comprising: A. a generally triangular shaped air foil including: i. a substantially rectangularly shaped solid first portion; ii. a substantially rectangularly shaped solid second portion; and, iii. means hingedly and adjustably interconnecting said first and second portions; B. mounting means for said air foil including: i. means connecting said air foil to said box by attaching a hinge to said box and to said substantially rectangularly shaped first portion on its free edge opposite the edge hingedly and adjustably interconnecting said first and second portion; ii. a plurality of parallel, spaced positioning brackets on said surface of said box hingedly and adjustably connecting the substantially rectangularly shaped second portion to said box by engaging the free edge of said second portion opposite the edge hingedly and adjustably interconnecting said first and second portions, whereby the angular configuration and position of said air foil can be adjustably varied by selectively connecting said free edge of said second portion to different positioning brackets on said box, and whereby said air foils are capable of movement to a stored inoperative position with respect to said box to minimize overall box dimensions.
Claim 9
Dependent Claim
204 words
A truck air foil mounted on the front surface of a box thereof, and the like, comprising: A. a generally triangular shaped air foil including: i. a substantially rectangularly shaped solid first portion; ii. a substantially rectangularly shaped solid second portion; and, iii. means hingedly and adjustably interconnecting said first and second portions; B. mounting means for said air foil including: i. means connecting said air foil to said box by attaching a hinge to said box and to said substantially rectangularly shaped first portion on its free edge opposite the edge hingedly and adjustably interconnecting said first and second portion; ii. a plurality of parallel, spaced positioning brackets on said surface of said box hingedly and adjustably connecting the substantially rectangularly shaped second portion to said box by engaging the free edge of said second portion opposite the edge hingedly and adjustably interconnecting said first and second portions, whereby the angular configuration and position of said air foil can be adjustably varied by selectively connecting said free edge of said second portion to different positioning brackets on said box, and whereby said air foils are capable of movement to a stored inoperative position with respect to said box to minimize overall box dimensions.
