Abstract
Abstract This invention describes a demountable type of air deflector device in the form of a triangular prism which can be attached to the upper front wall of a large van or semitrailer, and which extends over the top of the cab. The triangular shaped structure can have a closed top and bottom or, if desired, apparatus such as a refrigerating unit may be placed on the front wall of the van and air allowed to pass up through the air deflector past the refrigerating unit and up over the top of the van. Shock mounts may be provided for attaching the structure to the van, and means are provided for rapidly removing the deflector device as occasion demands.
