Description
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 hwd 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 watf;r 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. T'he locking
element is an
interfacing mechanism which provides the means for coupling to a recreational
vehicle's
holding tank waste outlet valve. The locking element is locatE:d on the
locking cap and is
fixed thereon. The locking cap is a cup shaped structure having an aperture
and a flter
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
2
CA 02462064 2004-03-26
cylindrical embodiment having a hollow interior and a thin gauged wall. The
outlet element
provides the housing means for the water extension wand. 7'he 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 vvater 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.

shorter than the
traditional method of back-flushing to disrupt the layer.
While these waste cleaning and removal devices may be suitable for the
purposes for which
they were designed, they would not be as suitable for the purposes of the
present invention, as
hereinafter described.
SUMMARY OF THE PRESENT INVENTION
The present invention discloses a device which can be used to remove waste
material and
debris from the holding tank of a recreational vehicle. The present invention
comprises an
outlet element being T or Y-shaped having an end cap on one end and a locking
cap on the
other end which locking cap connects by using a locking element to the tank
coupling valve
of the recreational vehicle. An extension wand which is connected to an inlet
water hose at
the inlet hose coupling element passes through O-rings disposed in the end cap
and the
locking cap whereby the extension wand travels or passes into the inner area
of the
holding tank. The extension wand has water outlet perforations on its end
which are disposed
interior of the holding tank so as to disperse the pressurized fluid
throughout the inner tank.
The waste material then exits through a filter means disposed in the locking
cap then through
the outlet element and into the outlet hose which is thereafter connected to a
septic tank
which receives the waste material from the interior of the holding tank.
A primary object of the present invention is to provide a waste containment
cleaning device
that may be used on recreational vehicles holding tanks.
Another object of the present invention is to provide a waste containment
cleaning device that
may have selectively attachable coupling means for the coupling with a sub-
level septic tanks
inlet valve.

CA 02462064 2004-03-26
Yet another object of the present invention is to provide a waste containment
cleaning device
that may be operational without the presents of chemicals.
Additional objects of the present invention will appear as the description
proceeds.
The present invention overcomes the shortcomings of the prior art by providing
a waste
containment cleaning device that is in expensive, light weight, easy t:o
manipulate, selectively
attachable to recreational vehicles (i.e. trailer, travel units and some mass-
passenger
vehicles).
The foregoing and other objects and advantages will appear from the
description to follow. In
the description reference is made to the accompanying drawings, which form a
part hereof,
and in which is shown by way of illustration specific embodiments in which the
invention
may be practiced. These embodiments will be described in sufficient detail to
enable those

other embodiments
may be utilized and that structural changes may be made without departing from
the scope of
the invention. In the accompanying drawings, like reference characters
designate the same or
similar parts throughout the several views.
