Abstract
An extendable and retractable step structure mounted to a recreational or like vehicle to facilitate passenger ingress and egress. The step structure basically includes a frame mountable to the vehicle beneath a doorway or other passenger ingress-egress location, at least one step tread and a movable linkage arrangement supporting the step tread from the frame for controlled movement between a retracted position wherein the step tread and the linkage arrangement are withdrawn into frame and an extended position wherein the step tread and the linkage arrangement are extended outwardly from the frame. Four embodiments are disclosed, two being equipped with a single step tread, a third having two step treads, and a fourth having three step treads, for selective use in differing vehicles having differing above-road elevations.
