ABSTRACT:
A stabilizing apparatus for rigidifying tubular, slide-out compartment support systems used in recreational vehicles and trailers. This apparatus employs one or more extensible tubular leg assemblies capable of being locked at selected lengths to fit terrain of the parked vehicle. Pairs of legs are adapted to form an A-frame in which the apex of the A is securely clamped to a single tubular slide out or underframe member. The legs are usually spread at an angle of 25-60.degree. from the vertical with foot pads at their outer ends substantially parallel to the ground level. Once so positioned the outer, lower ends of the spread legs are interconnected by a flexible strap equipped with a rachet tensioner or come along device whereby the strap may be tensioned to place the engaged attachment bracket under compression serving thereby to stabilize the slide out against lateral sway or movement. In other instances where the slide out compartment in supported on two or more laterally spaced slide rails, a single leg is clamped at an angle to each of such rails and then tensioned by the ratchet strap to laterally stabilize the slide out structure.
