Abstract: An anchoring system for mobile homes, trailers and similar vehicles in which a rod structure extending over the top of the vehicle is anchored on opposite sides of the vehicle and a resilient means is incorporated in the rod structure for maintaining tension on the rod structure to maintain the rod structure firmly in effective operating condition. A strap structure extending over the vehicle is anchored on opposite sides and beneath the vehicle, by anchoring devices held by a channel iron in runners or other supporting surfaces for the vehicle. Straps may also be connected to the frame and the anchoring device so that the vehicle is anchored over the top and at the frame by a dual type system.

Abstract: A stair construction in which a stair tread member is releasably clamped in position upon a pair of spaced tread support frame members in a manner such that a tubular sleeve of carpeting or other flexible tread covering material is simultaneously snugly, yet releasably, fitted in place on the tread member. The construction includes a pair of individual side frame assemblies in a parallelogram linkage form wherein the inclination of the prefabricated side frame assemblies can be adjusted as required in the field while maintaining the tread support frame members in a true horizontal position.
