Abstract
Abstract A stabilizer wing for a racing vehicle in which the wing includes a main airfoil to which a flap is attached at the trailing edge thereof. At least one and preferably two rudders are connected to the airfoil and extend upwardly therefrom with one of the rudders being fixedly positioned relative to the airfoil. The remaining rudder is pivotal relative to the airfoil and is connected by a suitable actuator to the flap so that as the racing vehicle rounds a curve the rudder is caused to pivot which in turn causes the flap to move to increase the downward pressure exerted upon the vehicle by the stabilizer wing.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
211 words
A stabilizer wing for use with a racing vehicle, said wing comprising an airfoil, means securing said airfoil to said vehicle in a position generally horizontal whereby wind in striking said airfoil during travel of said vehicle forces said vehicle downwardly against the road surface, said airfoil having a leading edge and a trailing edge, flap means pivotally connected to said airfoil at its trailing edge, a rudder projecting above and extending generally along the longitudinal dimension of said airfoil, means pivotally connecting said rudder to said airfoil wherein said rudder will be caused to shift about its pivot connection toward the airfoil when subjected to oncoming wind during travel of said vehicle in a turn, said flap means having an upper and a lower position, means interconnecting said rudder and flap means for causing pivotal movement of said flap means relative to the airfoil as said rudder shifts about its pivot connection with said flap means moving from its lower into its upper position as said vehicle is traveling in said turn and also for causing pivotal movement of said rudder relative to the airfoil as said flap means shifts about its pivot connection with said rudder moving away from the airfoil as said vehicle is traveling down a straightaway.
Claim 2
Dependent Claim
211 words
A stabilizer wing for use with a racing vehicle, said wing comprising an airfoil, means securing said airfoil to said vehicle in a position generally horizontal whereby wind in striking said airfoil during travel of said vehicle forces said vehicle downwardly against the road surface, said airfoil having a leading edge and a trailing edge, flap means pivotally connected to said airfoil at its trailing edge, a rudder projecting above and extending generally along the longitudinal dimension of said airfoil, means pivotally connecting said rudder to said airfoil wherein said rudder will be caused to shift about its pivot connection toward the airfoil when subjected to oncoming wind during travel of said vehicle in a turn, said flap means having an upper and a lower position, means interconnecting said rudder and flap means for causing pivotal movement of said flap means relative to the airfoil as said rudder shifts about its pivot connection with said flap means moving from its lower into its upper position as said vehicle is traveling in said turn and also for causing pivotal movement of said rudder relative to the airfoil as said flap means shifts about its pivot connection with said rudder moving away from the airfoil as said vehicle is traveling down a straightaway.
Claim 3
Dependent Claim
46 words
The stabilizer wing of claim 1 wherein said rudder has an upright position generally paralleling the direction of travel of said vehicle when the vehicle travels down said straightaway and a second position shifted in the direction of turn when said vehicle travels about said turn.
Claim 4
Dependent Claim
55 words
The stabilizer wing of claim 2 wherein said rudder and flap interconnecting means includes means for causing said rudder to shift from its second into its upright position as said flap shifts from its upper into its lower position due to the force of wind upon said flap during straight line travel of said vehicle.
Claim 5
Dependent Claim
42 words
The stabilizer wing of claim 3 and a second rudder projecting above and extending generally along the longitudinal dimension of said airfoil spaced laterally frOm said first mentioned rudder, means securing said second rudder in a fixed position relative to said airfoil.
Claim 6
Dependent Claim
15 words
The stabilizer wing of claim 4 wherein said second rudder extends in an upright position.
Claim 7
Dependent Claim
125 words
The stabilizer wing of claim 5 wherein said rudder and flap interconnecting means includes a rigid actuator rod connected at one end to said first mentioned rudder at a location spaced from the pivot connection of the rudder to the airfoil, the other end of said actuator rod extending slidably through said second rudder, cable and pulley means connected between said other actuator rod end and said flap at a location spaced from the pivot connection of the flap to the airfoil wherein movement of said first mentioned rudder into its second position causes said actuator rod to shift in the direction of said second rudder with said cable and pulley means causing said flap to be shifted from its lower into its upper position.
