Description:
FIELD OF THE INVENTION 
   This invention relates to a pressurized washing system. More particularly, this invention relates to a boat-mounted pressurized washing system for permanent installation and full integration into a boat or recreational vehicle for the purposes of washing the same and surrounding areas by delivering water expelled under high-pressure. 
   BACKGROUND OF THE INVENTION 
   Pressurized washing systems are relatively common. It is well known that the washing efficiency of a liquid such as water increases when delivered to the desired object to be washed under a higher pressure stream rather than at lower pressures. One common application and desired use for a pressurized-washing means is in the area of washing boats or recreational vehicles (RVs) such as motor homes and trailers, due to their tendencies of becoming frequently defiled, from salt, insects, birds and dirt from infinite sources. 
   It is old in the art to provide a portable means of supplying water under high pressure for the washing of such vehicles and the like. For example, U.S. Pat. No. 6,189,811, issued Feb. 20, 2001 to David Rudy, describes and illustrates a portable pressure washing system having a solar-voltaic power supply, to deliver a pressurized stream of water. 
   U.S. Pat. No. 5,975,423, issued Nov. 2, 1999 to Terrence D. Rice, teaches of a portable, fully self-contained pressure wash-down system, wherein the components are contained in a single enclosure, for storage and transportation thereof. Unfortunately, due to the weight of the enclosed components comprising the washing unit, i.e. battery, pump and motor unit, as well as the hoses, water supply means, and various nozzles, the system is rather heavy and burdensome to transport long distances. 
   Along these same lines, in an effort to help minimize the weight of these portable systems and make them less burdensome, smaller pumps implementing less heavy motors are generally utilized, thereby providing a significantly less powerful stream of water than may often be desired for a given purpose. Furthermore, the length of hose incorporated with these portable systems is limited to the small amount of storage space provided within the unit, often requiring the operator to frequently move the pressure-washing system from area to area when washing a large boat or RV. 
   Because of the aforementioned shortcomings of the prior art in this field, there is a need for a pressurized washing system with a more powerful pumping system, providing increased pressure delivery over the portable systems for use on vehicles such as boats or RVs, which can be permanently mounted and incorporated within such vehicles eliminating the burdensome transportation, unpacking, and setting up required by the portable systems of prior art. 
   SUMMARY OF THE INVENTION 
   It is therefore an object of the present invention to provide a self contained pressure washing system to be permanently mounted within a boat or in the alternative, an RV. 
   Another object of the present invention to provide a pressure washing system which can be fully integrated and hard wired into a boat&#39;s generator or shore-power supply, eliminating the need for extension cords or alternative power means. 
   It is also an object of the present invention to provide a pressure washing system for a boat having its own fresh water reservoir, in connection with an exterior filling means such as a remote quick connector fitting on the side of the vessel. 
   Another object of the present invention is to provide for an easily storable supply of hose, long enough to allow the user to wash all aspects of the boat or vehicle, eliminating the burden of coiling and storing lengthy hoses. 
   A further object of the present invention is to provide an easily accessible location on the boat or RV to access the remotely stowed hose supply, and having a quick-connector means for attachment of a spray nozzle thereto. 
   Finally, it is an object of the present invention to provide a fully integrated pressure washing system which can easily be incorporated into both newly manufactured vehicles, and retrofitted into older, existing boats or RVs, without sacrificing a significant amount of space therewithin. 
   The foregoing objects are accomplished in the preferred embodiment of the invention by providing a boat mounted pressure washing system, to be fully integrated and mounted within the boat. The pressure washing system comprises an internally mounted pump and drive unit, a fresh water reservoir, and a high pressure hose of predetermined length, and may be mounted in a variety of locations within the boat, such as the bilge, engine room, or storage cabinet. The fresh-water reservoir is hooked up to an external filling means having a quick connector located remotely on side of the boat for attachment of a dock-side hose, and supplies water to the pump unit. The output from the pump is connected to the high pressure hose, storable on an adjacent or remotely located recoiling hose reel. The length of the hose is determined by the user&#39;s individual preference, but is generally long enough to reach the entire length of the boat and immediate surrounding areas such as the dock. 
   The distal end of the hose is guided through a sleeve running inside the boat, and terminates in a quick-connection fitting positioned within an aperture on the exterior surface of the boat for connection with a nozzle of preference. When desired to activate and use the pressure wash system, the operator simply energizes the pump unit by turning on a corresponding power supply switch on the fuse panel of the boat, connects a nozzle to the fitting located on the end of the hose accessible through the aperture in exterior surface of the boat, and draws out the desired length of remotely stored hose to begin use. 
   Once finished, the user simply shuts off the power switch, removes the nozzle, and with the assistance of the spring-recoiled hose reel, guides the hose back through the access aperture located within the interior spaces of the boat. 
   As stated above, further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter, such as integrating the system into an RV or trailer. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses. Referring now to  FIG. 1 , the boat mounted pressure wash system  10  is shown, incorporated and in use with a boat  12 . The mounting location within the boat  12 , and actual type of boat  12  with which the pressure wash system  10  is shown is not intended to limit the scope of the present invention&#39;s applications. Specifically, in an alternative application not illustrated, the pressure wash system  10  of the present invention may be mounted in conjunction with a recreational vehicle (RV) or camper trailer. 
   Referring now to  FIGS. 1 and 2  together, the individual components of the pressure wash system  10  are more clearly illustrated. Comprising four primary components: a fresh water reservoir  20 , a pressurizing pump  30 , a hose storage reel  40 , and a high pressure hose  50  of predetermined length, the pressure wash system  10  may be mounted either unitarily as a whole, or separated so as to allow individual components to be remotely located, providing more flexibility for the system  10  to be adaptable to individual boat applications. 
   The fresh water reservoir  20  used for holding a supply of water for the pressure wash system  10 , has a predetermined volume and is mounted within the interior spaces of the boat, such as the bilge or engine compartment. Other mounting locations such as within a storage cabinet or closet may also be utilized depending upon the users preference, available space and ease of accessibility. The reservoir has a general water supply line  22  connecting between the reservoir  20  and the outside surface of the boat  12 , whereby terminating in a universal hose fitting  24 . The reservoir  20  is easily refilled with fresh water when depleted, by attaching a hose from the dock-side water supply to the universal fitting  24  located on the outside of the boat  12 . The installation of the water supply line requires only minor modification to the boat  12  in terms of cutting a single aperture  25  in the desired, location on the boat  12 , proximal the mounted reservoir  20  within the boat, and routing the supply line  22  between the reservoir  20  and the fitting  24  mounted through the aperture  25 . 
   While specific reference has been made above to using a dockside water for the water source utilized by the pressure wash system, the present invention is intended to further encompass applications where the water source for the wash system is provided by water stored in the built in on-board water tanks, commonly provided on both marine vessels and recreational vehicles. 
   The reservoir  20  further connects to a pump supply line  26  which feeds water stored within the reservoir  20  to the pressurized pump  30  during use of the pressure wash system  10 . The pressurized pump  30  is of a high pressure liquid pumping unit readily available on the market, and generally will be one universally used for all applications of the system  10 . Alternatively, a plurality of different pumps  30  may be implemented, depending on individual users performance preference, but regardless of which type of pump  30  is utilized in each installation, the drive motor implemented in the pump will be of marine grade, having sparkless brushes for marine applications. The pressurized pump  30  motor is designed to be hard wired directly into the boat&#39;s AC shore supply or generator power supply  32 , eliminating any need for extension cords, or additional circuitry when energizing the pump  30  motor. By providing a means for the pump  30  to be energized with either AC shore power or generator power, the pressure washing system  10  may be utilized while the boat  12  is out to sea, thereby supplying the pump  30  with power from the boat&#39;s generator. In the alternative, while the boat is docked, the pressure washing system  10  may be utilized wherein the pump  30  may be energized with AC shore power supplied to the boat by a power cord from the shore, thereby conserving fuel in not requiring the boat&#39;s  12  generator to be operating continuously. A circuit breaker dedicated to the pressure wash pump  30  is remotely located on the fuse panel of the boat  12 , whereby the power supply  32 , either shore power or generator provides for energizing the pump  30  when the user activates the circuit. 
   The pump  30  supplies a pressurize supply of water from the reservoir  20  to a high pressure hose  50  of predetermined length by means of a pressure supply line  41  connected to the permanently mounted hose reel  40  located inside the boat  12  either proximal to the pump  30 , or located elsewhere within the boat. The hose reel  40  of which several currently marketed designs may be utilized with the system  10 , releasably stores the high pressure hose  50  in a series of coils upon the reel, and has a spring loaded or electromechanically assisted recoiling means  42  for selectively winding or unwinding the hose  50  from the hose reel  40 . The recoiling means  42  allows the user to withdrawal the hose  50  from the reel  40  when so desired, lock the reel at any position to utilize the pressure wash system  10 , and subsequently provide for returning the hose  50  to the reel  40  when finished. The hose reel  40  also depicted in  FIGS. 4 and 5 , has a slidable guide means  44  attached to a lateral track  46  implemented into the reel  40 , for guiding the hose  50  evenly onto the hose reel  40  during recoiling. The specific length of the high pressure hose  50  is predetermined by the user&#39;s preference and available storage space, but generally when fully extended, will be of a length significantly longer than the length of the boat  12  upon which the system  10  is mounted, thereby providing for enough hose  50  length to wash the entire boat  12  and surrounding areas. 
   Referring now to  FIGS. 3 ,  4 , and  5 , the distal end  52  of the high pressure hose  50  is fed from the reel  40  through a flexible sleeve  54  having a greater inside diameter than that of the high pressure hose  50 . The sleeve  54  provides for a guiding means to slidably guide the high pressure hose  50  from the remotely mounted hose reel  40  to an aperture  56  located remotely outside the boat  12 . The distal end  52  of the hose  50  outside the boat  12  terminates in a quick release fitting  58  for attachment to a removable spray nozzle  60 , and further has a recoil-stop means  55  located on the distal end, providing for a preventative means of full retraction of the hose  50  into the inside of the boat  12  due to the recoiling means of the hose reel  40 . The recoil-stop means  55  comprises an annular bushing of rubber or plastic having a greater diameter than the aperture  56  thereby preventing full retraction of the distal end  52  of the hose  50  into the boat  12 . 
   Referring to  FIGS. 4 and 5 , the aperture  56  and corresponding high pressure hose  50  access may be positioned in a variety of locations on the outside of the boat  12  pursuant to the users preference and accessibility, whereby installation requires only minor modification in terms of cutting a single hole in the desired, remote location on the boat  12 . Specifically,  FIG. 4  shows the hose access aperture  56  on a horizontal deck surface  13  of a boat  12 , wherein an alternative embodiment of the present invention,  FIG. 5  shows the hose access aperture concealable within a cabinet or access panel  15 . 
   As mentioned above, the scope of the present invention is not intended to be limited to installations on boats of either power or sail. The pressure wash system  10  may be just as easily adapted for mounting in conjunction with a recreational vehicle (RV) or camper trailer and can be installed during the manufacture of new vehicles, as well as being retrofitted into older, existing boats or RVs. 
   The description of the invention is merely exemplary in nature and, thus, variations that do not depart from the gist of the invention are intended to be within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
