Abstract: A worktop assembly for use in a travel trailer including a first structural portion, a second structural portion and a plurality of bracket assemblies. The first structural portion has a first end and a second end and the second structural portion has a first end and a second end. The plurality of bracket assemblies include a first bracket assembly and a second bracket assembly. The first bracket assembly is connected to the first structural portion proximate to the first end and to the second structural portion proximate to the first end. The second bracket assembly is connected to the first structural portion proximate the second end and the to the second structural portion proximate to the second end. Each bracket assembly has a plurality of pivot points.

Abstract: The powered ramp door lift is used in cargo trailers and other ramp door applications and includes a powered winch assembly, a pair of wire cables or nylon straps connecting the winch assembly to the ramp door, and a “pusher” mechanism. The winch assembly mounted to the trailer header winds and unwinds the cables onto a pair of spools mounted to a drive shaft, which is driven by an electric motor. The “pusher” mechanism prevents the “unspooling” problems that effect the operation of winches in automated ramp door applications. The pusher mechanism engages the ramp door in the closed position and applies an outward force to the ramp door over a small portion of its travel to assist in the initial lowering of the ramp door from the closed position. The winch assembly also includes a cable tension winch shut off mechanism, which deactivates the winch motor in the absence of any tension on cables.

Abstract: A convertible sofa-bed which includes a support frame. A seat support is slidably connected to the support frame by a roller and a back support which is pivotally connected to the seat support. The back support includes a hook part which provides for positive connection of the back and seat supports to assure smooth transitional shifting.
