Abstract
Abstract A waste dispensing device for recreational vehicles includes an elongate longitudinally compressible and extensible hose which is connected to the waste outlet fitting of a recreational vehicle. The dispensing device includes an exterior housing structure which is secured to and positioned around that end portion of the hose which is connected to the recreational vehicle. The hose may be longitudinally retracted and contained within the exterior housing structure when the vehicle is being moved, and conversely, the hose may be longitudinally extended for connection to a waste disposal system, when the vehicle is stationary.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
188 words
A waste dispensing device for recreational vehicles and the like comprising: an elongate, flexible inner tubular member being longitudinally retractable and extensible between an extended position and a retracted position, a coupling element secured to one end of said tubular member and being adapted to be attached to the waste outlet fitting of a recreational vehicle, an elongate, rigid spout secured to the other end of said tubular member and projecting longitudinally therefrom, an elongate, exterior housing structure positioned around said inner tubular member and including an elongate rigid cylindrical sleeve and an elongate flexible outer tubular member, said outer tubular member having one end thereof connected to said coupling element and having the other end thereof connected to said rigid sleeve, said exterior housing structure having a length dimension substantially less than one-half the length dimension of the inner tubular member when the latter is in the extended position, an annular clamping cap positioned around and connected with said spout, the clamping cap releasably engaging an end portion of said rigid sleeve to retain the inner tubular member in a retracted position within said exterior housing structure.
