Abstract
An elongate frame such as for carrying vehicles includes length-adjusting and width-adjusting assemblies that enable the frame to fully occupy differently-sized enclosures. Pivotably extensible and retractable length-adjusting sections form the length-adjusting assembly. Several length settings are achievable by selectively unlocking different combinations of sections. Overshooting of settings is avoided, despite machine-driven adjustment, by elimination of overtravel-type movement in each section. Telescopically adjustable joints, each with automatic end position latching and backup stop protection, form the width-adjusting assembly and guide the frame's sides in stable upright movement while the frame's forward end is unfolded. Minimal restrictions on vehicle size are achieved by a vehicle-supporting assembly including variable-tread wheel cradle supports, lengthwise-shifting posts which, together with the supports, establish length-adjustable vehicle-loading zones, an adapter assembly which operatively couples the width-adjusting assembly and each support to optimize tolerance for wider treads based on the width setting selected, and a toothed plate interface which operatively c…
