Collapsible airfoils which reduce wind resistance in their operational positions on the front and rear of a vehicle are moved with minimum effort to and from collapsed stored positions on the sides of the vehicle, such as a truck. Slide mechanisms for the folding airfoil sections are provided front and rear on the vehicle side walls. A secure locking device for the airfoils in their erected operational positions is provided.
1. An airfoil to lessen wind resistance in truck bodies and the like comprising a collapsible and erectable airfoil consisting of two companion airfoil sections each having folding panels and an attached internal folding support frame, supporting guide rail means for each airfoil section on the two side walls of a truck body equipped with the airfoil including a pivoted strut, at least one panel of each airfoil section having a locking element thereon, a coacting locking element receiver on the adjacent end wall of the truck body, said supporting guide r...
