Abstract

See full text

A rotatable telescoping drain assembly permanently mounted at the end to waste receptacle drain on the underside of a recreational vehicle consisting of a swivel coupling unit attached to an axially extensible flow hose within a telescoping support tube assembly, a tie rod assembly connected to and extending between the tube assembly and the swivel coupling unit, and a discharge spout unit connected to the other end of the telescoping support tube and flow hose assembly which includes an internal valve. The telescoping tube assembly can be relatively telescoped, the swivel coupling relatively swiveled, and the tie rod relatively pivoted to locate the spout into the inlet of appropriate waste storage facility. During travel of the vehicle the discharge spout and drain assembly is supported within an enclosed cabinet mounted on the vehicle. The telescoping drain assembly allows the vehicle operator to conveniently avoid the usual mess associated with emptying liquid waste receptacles on the vehicle.
