ABSTRACT:
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates generally to a waste containment-cleaning device and, more specifically, to a waste containment-cleaning device that may be selectively attached to a recreational vehicle in order to clean and maintain a recreational vehicle holding tank. The present invention is a holding tank cleaning device having a selectively attachable septic tank coupling adapter, and having a selectively extendable retractable water extension wand. The holding tank cleaning device consists of a water hose extension wand, one rubber gasket O-rings, a locking element, a locking cap, an outlet element, a locking band, an end cap, an intake hose coupling element, and an outlet hose having a septic tank coupling adapter at one of its distal ends. The water extension wand is an elongated cylindrical shaped flexible structure having an orifice extending through the length thereof. The water extension wand is furnished with a series of perforations at one of its distal ends and an intake hose-coupling element at the other distal end. The water extension wand provides the means for delivering pressurized fluids into a recreational vehicles holding tank. Also the water extension wand may receive its pressurized fluid load via a water hose that may be coupled to the intake hose-coupling element. The water extension wands perforations located at one of its distal ends provides the means for projecting a pressurized fluid load in various directions in order to access and clean hard to reach sections of a recreational vehicles holding tank. The intake hose coupling device is an adaptive fitting that provides the means for the water extension wand to be selectively coupled to pressurized water hose adapter. The rubber gasket o-rings resembles that of a conventionally manufactured rubber gasket o-rings. The rubber gasket O-rings provides the means for a leak resistant seal around the water extension wand as it slides through the end cap and the locking cap. The rubber gasket O-rings are located one in the locking cap and the other in the end cap. The locking element is an interfacing mechanism which provides the means for coupling to a recreational vehicles holding tank waste outlet valve. The locking element is located on the locking cap and is fixed thereon. The locking cap is a cup shaped structure having an aperture and a filter therein. Also the locking cap provides the means for retaining the components within said invention as it works in conjunction with the outlet element and the end cap. The locking cap is located at one of the distal ends of the outlet element. The outlet element is a T-shaped cylindrical embodiment having a hollow interior and a thin gauged wall. The outlet element provides the housing means for the water extension wand. The outlet element having three ends is coupled to the front cap at one of it ends, coupled to the end cap at yet another end, and coupled to the outlet hose at the other end. The outlet element provides transfer medium for waste material as it is cleaned out of a holding tank and travels down the outlet hose. The end cap is a modified cup shaped structure having an aperture therein. The end cap provides the retaining means for the components that comprise said invention when used in conjunction with the outlet element and the locking cap. Also the end cap provides supportive means for the water extension wand as it traverses through the aperture of the end cap, through the outlet element and through the aperture of the locking cap. The locking band resembles that of a conventional selectively adjustable band clamp and provides the coupling means for the outlet hose and the outlet element. The outlet hose is a high pressure drainage hose fitted with a conventional septic tank coupling adapter at one of its distal ends and having said invention coupled to the other distal end. The outlet hose provides the sewage evacuation means for the holding tank of a recreational vehicle. The user of said invention may selectively attach said invention to the outlet valve of a recreational vehicles holding tank. The user of said invention may then introduce pressurized water into the holding tank via a water hose as it works in conjunction with the water extension wand. The water extension wand protrudes from the locking cap and is interfaced with the inner cavity of the recreational vehicle holding tank. A volume of pressurized water is forced into the inner cavity of the recreational vehicle holding tank and it forced out of the tank via the locking caps. The waste matter from the holding tank is the flushed through the outlet element, then in turn flushed down the outlet hose and into a sub-level or other type of septic tank.

An extension spray gun comprising a plurality of hollow pole sections telescopically secured together to form an extendable pole having a spray nozzle secured to one end of the pole and a valve secured to the other end of the pole to control flow of paint through a flexible hose extending between the valve and the nozzle. Paint is delivered from the hose to a chamber formed in the nozzle and flows through a passage in the nozzle to a spray tip. A valve element in the chamber is spring urged to close the passage when pressure of paint in the chamber is less than the predetermined pressure.

Apparatus for storing a recreational vehicle sewer hose assembly comprising spaced cone members affixed to a central aperture mandrel with one cone element being slidably received respective to the mandrel and to the remaining fixed cone element. The mandrel is aperture and has an inlet end which can be connected to a water supply that the slidable cone can be removed from the mandrel, a sewer hose assembly telescopingly received in a collapsed manner about the mandrel, and the slidable cone member replaced upon the mandrel with the collapsed sewer hose being captured so that it is in stored relationship therebetween. During the above manipulation, water flow into the mandrel and through the apertures to wash any accumulation of sewage from the interior of the hose assembly. This expedient enables the entire apparatus to be subsequently drained so that the entire combination can be conveniently handled and stored in a sanitary and compact manner.

A tank flushing apparatus designed in particular to be utilized in conjunction with a toilet waste holding tank. The tank flushing apparatus includes a connector assembly to facilitate attachment to a hose which in turn extends from a source of liquid, such as water. The connector assembly is attached to an elongated conduit, the inner end of which is formed into a nozzle assembly. The nozzle assembly extends through a hole formed within the holding tank and is constructed also to form a liqu
