ABSTRACT:
An improved retractable bed comprises two or more telescoping rail packs with a deck attached therebetween for supporting a cargo. Each rail pack comprises a strong and rigid intermediate rail interposed between a base rail fixed to a support surface and a primary rail. The intermediate rail has one set of support rollers for rolling along the base rail, and a second set of support rollers for rollingly supporting the primary rail. Two sets of guide rollers laterally retain the intermediate rail to the base rail and the intermediate rail to the primary rail. The present invention includes caliper brakes that act between the primary rail and base rail to selectively lock the rail packs at desired locations. A screw and handle mechanism may also be used to translate the retractable bed and to lock it relative to a support surface.
