ABSTRACT:
A self-storing step assembly comprises an upright U-shaped member having a pair of parallel legs each reciprocally mounted in a tubular housing secured to a vehicle. A compression coil spring is disposed in each of the housings, between a pair of annular guide members, to engage a respective one of the legs to raise the step member to its stored position and to permit a workman to engage the step member with his foot to move it downwardly against the force of the springs to a lowered position.
