Abstract
Abstract A foldable retractable step assembly for campers and like vehicles comprises a bracket with means for attachment to a structural support member of a camper. At least one step and riser, preferably a plurality of steps and risers, are suspended on the bracket. Pivotal mounting means with associated stop means pivotally mount the upper end of the upper riser on the bracket and the upper ends of the subsequent risers on the outer ends of the adjacent steps. Pivotal mounting means mount the inner ends of the steps on the lower ends of the risers. The steps and risers thus are alternately adjustable between an extended use position, and a folded, nesting, transport position underlying the bracket. Retracting means are associated with the bracket which enable retraction of the folded assembly beneath the support when the assembly is in transport position.

A folding, retractable step assembly for entering a door of a camper or the like, the step assembly comprising: a. a pair of laterally spaced brackets each having a longitudinal slot, b. attaching means for attaching the brackets to a structural support member of the camper, c. a pair of laterally spaced first angle iron risers one inward of each bracket, one leaf of each riser being parallel to its associated bracket and the other leaf of each riser projecting inward toward each other from the inner side of said one leaf, d. a pivot on each first riser slidably engaging the slot in the associated bracket for movement of the first risers between a retracted position within and parallel to the brackets and an extended position projecting downward from the front end of the brackets, e. a pair of stop members on each bracket spaced apart vertically and longitudinally for engaging opposite sides of the associated first riser in the extended position of the latter while permitting the first risers to slide between them to and from said retracted position, f. a pair of laterally spaced first angle iron step supports one inward of each first riser, one leaf of each step support being parallel to said one leaf of the associated first riser and the other leaf of each step support projecting inward toward each other from the inner end of said one leaf, g. a pivot interconnecting the outer end of said one leaf of each first riser and the inner end of said one leaf of the associated first step support, h. the end of said other leaf of each first riser and associated first step support adjacent the interconnecting pivot being arranged for mutual abutment in the extended position of said step supports, i. a first step member supported between said other leaves of the step supports, j. a pair of laterally spaced second angle iron risers, one inward of each first step support, one leaf of each second riser being parallel to said one leaf of the associated first step support and the other leaf of each second riser projecting inward toward each other from the inner side of said one leaf, k. a pivot interconnecting the outer end of said one leaf of each first step support and the inner end of said one leaf of the associated second riser, l. said other leaf of each first step support terminating at its outer end inward of its associated one leaf and forming an abutment for the associated second riser in the extended position of the latter, and m. a second step member pivoted to the outer ends of the second risers, the inner end of the second step and the outer ends of the second risers being arranged for mutual abutment in the extended position of the second step, n. whereby the second step may be folded removably against said other leaves of said second risers, the second risers may be folded removably against said other leaves of said first step supports, and the first step supports may be folded removably against said other leaves of the first risers.
