ABSTRACT:
An energy-saving streamlining structure for the fronts of motor trucks, motor homes, buses and the like, comprises when deployed a forward-pointing transparent conical shell supported on the front of a truck by a stem generally axial to the shell; telescoping and rotary linkages of the stem fold the shell into damage resistant horizontal opposed-segment or bow-tie storage-configuration compactly retracted against the front of the vehicle. Transparent panels provide driver-view of the highway through the unit, anti-shake spring biasing stabilizes the mechanism when deployed, and power drive provides for remote control operation from the truck cab at all times. Compactness and integration of the parts adapt the unit for after-market attachment and capability for transfer from one vehicle to another as well as for installation as original equipment at the factory; in an embodiment provision is made for the invention when deployed to return to storage mode when the vehicle reduces speed to a predetermined rate.
