Abstract:
This is a portable, pressurized washing system for use in various situations. It is designed to provide low power, medium to low pressure water at high volumes. Its initial application is for use in equestrian applications. The basic design allows for easy mounting inside a horse trailer, and will supply water under pressure to a user outside the trailer who wishes to hose off a horse, equipment or the trailer itself. There are obviously other applications outside equestrian uses, such as but not limited to, mountain biking, motor-crossing or even SCUBA diving.

Description:
BACKGROUND OF THE INVENTION  
       [0001]     As any equestrian knows washing hot horses after any grueling event, such as Hunter Paces or Eventing, when away from the home barn, can be difficult and dirty. Most often, a equestrian will take a closed container of water, pour it into a bucket, and use a sponge to wipe down his/her horse. This results, rather quickly, in dirty water in the bucket, dirty water splashed on the rider and more irksome it can result in dirty water splashed on the rider&#39;s clean breeches—clean breeches that are needed for another event that day. Furthermore, the water from the water bucket and sponge is obviously not under any pressure, nor is it clean after the first sponge rinse, as mentioned above, and thus does not effectively wipe the sweat and dirt from the horse&#39;s hide.  
         [0002]     Thus was born this device, which the inventor has trade named “The Hoser”. It is simple in concept and can be adapted to a wide variety of usages and configurations. The inventor initially created the Portable Self-Contained Water Supply and Pressurized Method of Distributing Water for use with his own horses in his own horse trailer. The first implementation was a large, closed, plastic container of water, strapped inside the trailer, with a pump mounted on top of that tank, and with a hose attached to the discharge port of the pump. Thus, he could easily extend the hose that is attached to the plastic container, out of the trailer and spray down his horses with pressurized water. The horses were cleaner and happier, he never got dirty with a dirty sponge and water, and so he never had to bring the water bucket and sponge to another event again! 
         [0003]     Since that time many other methods of employing the Portable Self-Contained Water Supply and Pressurized Method of Distributing Water device have been contemplated. For instance, it can also be readily adapted to other sports, such as dirt biking, SCUBA diving and mountain biking—in fact it can be adapted for any sport that needs to hose down equipment or animals away from home.

       SUMMARY OF THE INVENTION  
       [0010]     This is a portable, pressurized washing system for use in various situations. It is designed to provide medium to low pressure water at high volumes. Its initial application is for use in equestrian applications. The basic design allows for easy mounting inside a horse trailer, and will supply water under pressure to a user outside the trailer who wishes to hose off a horse, equipment or the trailer itself. The device is comprised of five major subassemblies, a main water tank, a pump, a hose and hose assembly, a mounting method, and an electrical system. The device is completely self contained, in that at the remote location, there is no need for an external water supply, nor is there a need for any other equipment, such as an air compressor. There are obviously other applications outside equestrian uses, such as but not limited to, mountain biking, motor-crossing, boating or even SCUBA diving. This Portable Self-Contained Water Supply and Pressurized Method of Distributing Water device is designed for ease of use, compactness and portability. To that end the inventor designed this device with those concepts in mind. For instance, the current preferred embodiment is on wheels, but also has a hold down hooking block. This allows the user to employ this invention by either leaving it in place and extending the hose outside of the trailer, or by wheeling it outside the trailer by use of chrome plated steel handlebars and rust resistant plastic wheels to a more desirable location. The main water tank further demonstrates the ease of use design. There is a finger screw cap on the topside of the main water tank. This screw cap can be easily twisted and removed to allow a user to easily, and quickly fill the device with water from a home water spigot or hose. Finally, the hose storage compartment makes the invention not only easy to use, but also compact. The hose storage compartment will neatly store the hose, so the hose does not present an entanglement hazard. The following description relays some additional desired functionality, but in no way limits the scope of this invention.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0014]     The terminology used herein should be interpreted in its broadest reasonable manner, even though it is being utilized in conjunction with a detailed description of a certain specific preferred embodiment of the present invention. This is further emphasized below with respect to some particular terms used herein. Any terminology that the reader should interpret in any restricted manner will be overtly and specifically defined as such in this specification. The preferred embodiment of the present invention will now be described with reference to the accompanying drawings, wherein like reference characters designate like or similar parts throughout.  
         [0015]     As mentioned in the Summary of Invention, the Portable Self-Contained Water Supply and Pressurized Method of Distributing Water device is comprised of five major sub-assemblies. These include the main water tank ( FIG. 1 ), a hose and hose assembly ( FIG. 3 ), and electrical system ( FIGS. 1 and 2 ) and a pump ( FIGS. 1 and 2 ). Each sub-system will be described in kind.  
       Main Water Tank  
       [0016]     In this preferred embodiment the main water tank  1  (as shown in  FIG. 1 ) is a 30-gallon standard drum like tank made out of opaque high-density polyethylene (HDPE). However, the main water tank  1  (as shown in  FIG. 1 ) can come in various sizes and shapes depending on the water usage requirements and placement requirements for a given application. For instance, the main water tank  1  (as shown in  FIG. 1 ) could be a 60-gallon square container that is affixed in the rectangular storage compartment found on the front of many horse trailers. Additionally, the main water tank  1  (as shown in  FIG. 1 ) can be made out of any durable material and can be optionally impregnated with color to suit the taste of a user. The main water tank  1  (as shown in  FIG. 1 ) is further comprised of a filler with finger screw cap  16  (as shown in  FIG. 2 ), a water tank siphon port  21  (as shown in  FIG. 3 ), handlebar mounts  17  (as shown in  FIG. 2 ), a hose storage compartment  15  (as shown in  FIGS. 1 and 3 ), a battery compartment  14  (as shown in  FIG. 2 ), a hold down hooking block  19  (as shown in  FIG. 2 ), wheel axle mounts  18  (as shown in  FIG. 2 ) and a resting foot  22  (as shown in  FIG. 3 ). Affixed to the main water tank  1  (as shown in  FIG. 1 ) are chrome plated steel handlebars  6  (as shown in  FIG. 1 ), galvanized steel wheel axles with retaining nuts and washers  13  (as shown in  FIG. 1 ), and rust resistant plastic wheels  11  (as shown in  FIG. 1 ) with rubber tread  12  (as shown in  FIG. 1 ). Of course, the inventor contemplates materials other than chrome plated steel handlebars, galvanized steel wheel axles, and rust resistant plastic wheel. The inventor further contemplates additional means of moving this invention other than by use of wheels and/or handlebars.  
       Pump  
       [0017]     The pump  2  (as shown in  FIGS. 1 and 2 ), in this preferred embodiment, is a 12-volt DC, 5 amp, 3 gallon per minute at 45 pounds per square inch (PSI), self-priming, auto shutoff water pump. A water siphon tube with compression fittings  7  (as shown in  FIG. 3 ) is affixed to the water siphon port  21  (as shown in  FIG. 3 ), and to the inlet port of the pump  2  (as shown in  FIGS. 1 and 2 ). A pump outlet pressure line with compression fittings  20  (as shown in  FIG. 2 ) attaches at one end to the discharge port of the pump and terminates with a fitting to which the plastic coiled standard hose  9  (as shown in  FIG. 3 ) attaches. The inventor fully contemplates that the actual size and gallons per minute delivery of the pump, and diameter of the siphon tube, will depend on the application. Additionally, in this preferred embodiment, the actual pump  2  (as shown in  FIGS. 1 and 2 ) is affixed to the to a galvanized steel mounting bracket  3  (as shown in  FIG. 1 ). This galvanized steel mounting bracket  3  (as shown in  FIG. 1 ) creates a stable, durable, rust proof method for attaching the pump  2  (as shown in  FIGS. 1 and 2 ) and in turn is affixed to the main water tank  1  (as shown in  FIG. 1 ). Of course, as with all other aspects of this invention, the inventor fully anticipates that the method of affixing the pump to the water tank can and will change to meet the circumstances in which this invention is used.  
       Electrical System  
       [0018]     The present embodiment of this invention uses a lead acid battery  8  (as shown in  FIG. 2 ) to power the pump  2  (as shown in  FIGS. 1 and 2 ). The lead acid battery  8  (as shown in  FIG. 2 ) fits snugly into the battery compartment  14  (as shown in  FIG. 2 ) and is wired, as appropriate, to the pump  2  (as shown in  FIG. 2 ), the environmentally sealed, power on/off, single pole single throw (SPST), toggle switch  4  (as shown in  FIG. 1 ) and power indicator lamp  4  (as shown in  FIG. 1 ). The environmentally sealed, power on/off, single pole single throw (SPST), toggle switch  4  (as shown in  FIG. 1 ) is mounted into the galvanized steel mounting bracket  3  (as shown in  FIG. 1 ) and wired into the electrical circuit. Along with the environmentally sealed, power on/off, single pole single throw (SPST), toggle switch  4  (as shown in  FIG. 1 ) there is a power indicator lamp  4  (as shown in  FIG. 1 ). This power indicator lamp  4  (as shown in  FIG. 1 ) is simply used to easily show the user whether the device is powered on or not and is wired in parallel to the power leading to the pump  2  (as shown in  FIGS. 1 and 2 ). Upstream of the environmentally sealed, power on/off, single pole single throw (SPST), toggle switch  4  (as shown in  FIG. 1 ) (i.e. between the toggle switch and the battery a fuse is placed to prevent accidental overloads. It should be noted that the inventor might also modify this design so that the device can be powered by an external power source such as a car battery or other power sources. Additionally, the inventor fully anticipates that other designs of this same device will not have a self-contained battery and therefore the device&#39;s electrical requirements will be modified to be easily hooked up to, and run off of, a standard car battery, or the like. For example, an application of this device could power the pump by establishing a connection to the horse trailer&#39;s electrical system via a socket on a standard trailer hitch. Alternatively, other electrical hookups schemes could use in-line splicing to a car or trailer&#39;s electrical system.  
       Hose and Hose Assembly  
       [0019]     The hose, in this preferred embodiment is a half-inch standard coiled plastic garden hose  9  (as shown in  FIG. 3 ). It attaches at one end to the pump outlet pressure line with compression fittings  20  (as shown in  FIG. 2 ) and terminates by screwing into a typical multi-mode garden style spray nozzle  10  (as shown in  FIG. 3 ). The hose  9  (as shown in  FIG. 3 ) can be of various lengths depending on the application. The spray nozzle  10  (as shown in  FIG. 3 ) is an integral part of this design and allows a user some measure of control over how the water is delivered (i.e. in different water stream shapes, such as mist, cone, flat, jet, shower, angled, or vertical).  
       Mounting Method  
       [0020]     The preferred embodiment of this device has provided for a simple, yet effective mounting method. A hold down hooking block  19  (as shown in  FIG. 2 ) is levered onto a plate screwed into the floor of a horse trailer. This stops the device from rolling around when the trailer (or other locomotion apparatus) is under way. Additionally, the user could use bungee or Velcro straps to hold the handlebars tight against the walls of the trailer. The inventor also contemplates the use of a storage box found on the front support member of many horse trailers to house and secure an appropriate water tank.  
         [0021]     The foregoing description and methods detail certain preferred embodiments of the present invention and describe the best mode contemplated. It will be appreciated, however, that no matter how detailed the foregoing description appears, the invention can be practiced in many ways without departing from the spirit of the invention. Therefore, the description contained in this specification is to be considered exemplary, rather than limiting, and the true scope of the invention is only limited by the following claims and any equivalents thereof.
