ABSTRACT:
A folding step for vehicles, and specifically for use on the front bumpers of large semitrailer tractors. The step is used for servicing the vehicles, for example, cleaning the windshield and the like and yet will permit the step to be folded up very quickly for transport position. It also may be used as an entrance step for vehicles. The step automatically locks under spring pressure in either its usable or stored positions, and thus minimum time is utilized in operating the step, and safety is enhanced.
