Abstract
Abstract A rectangular platform is removable secured horizontally by one side to one side wall of a mobile home below the lower limit of its door. A pair of telescoping legs are pivotally connected in depending relation to the opposite side of the platform in underthe-platform folding relation. A pair of steps are similarly connected with and supported by pairs of bars pivotally connected with the platform in a downwardly and outwardly projecting direction. Hand rails are supported by upstanding supports pivotally connected with marginal side edges of the platform. The hand rail supports, legs and pairs of step supporting bars are foldable towards the respective upper and lower surfaces of the platform for collapsing and rendering the device portable.
