Telescoping drain assembly for recreational vehicles

In combination with a recreational vehicle having a discharge pipe for liquid waste, a telescoping drain assembly movable between a storage position and an operating position for transporting liquid waste from said discharge pipe to a discharge location spaced from said vehicle, said telescoping drain assembly comprising a swivel coupling unit comprising a pair of relatively rotatable aligned tubular members rotatable about an axis in the direction of waste discharge through said coupling unit, one of which members is connected to said discharge pipe, an axially extensible flow hose of flexible construction connected to one end of the other one of said tubular members, a telescoping tube assembly having a pair of ends and comprising a plurality of axially telescoped tubes positioned about said flow hose at a position spaced from said coupling unit, a tie rod assembly connected to and extending between one end of said tube assembly and said coupling unit, said tie rod assembly comprising tie rod members pivotally connected for pivotal movement about an axis extending transversely through said flow hose at a location spaced from said coupling unit, a discharge spout unit connected to the other end of said telescoping tube assembly, and a valve member in said discharge spout unit movable between open and closed positions, whereby said telescoping tube assembly can be relatively telescoped to locate said spout a desired distance from said vehicle and said swivel coupling members can be relatively swiveled and said tie rod members relatively pivoted about said transverse axis to locate said spout at a desired position located to one side of and below said discharge pipe.
