     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1-7 thereof, a new portable washing cart embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, it will be noted that the portable washing cart 10 comprises a main body 12 having a hollow interior enclosed by a left front door 14 pivotally mounted to a left vertical edge of the main body and a right front door 16 pivotally mounted to a right vertical edge of the main body, as shown in FIG. 1 of the drawings. A left top door 18 is pivotally mounted to a left horizontal edge of the main body, with a right top door 20 being similarly pivotally mounted to a right horizontal edge of the main body. As shown in FIG. 2, the doors 14-20 can be opened to facilitate or permit access into the interior of the main body. Preferably, the top doors 18 and 20 engage upper edges of the front doors 14 and 16 when opened so as to be supported in a substantially horizontal orientation to permit use of the top doors as a support surface or counter. If desired, wheels or casters 21 can be rotatably mounted to the main body 12 to facilitate rolling movement of the device 10 across a floor or ground surface. A handle 23 can be secured to a side of the main body 12 for facilitating manual acceleration of the device in cooperation with the wheels 21. Further, a linen basket 25 can be secured to a side of the main body 12 for receiving clean or soiled linen. 
     With continuing reference to FIG. 2, it can be shown that an interior counter top 22 is mounted within the interior of the main body 12. A fixed sink 32 is fixedly mounted within an aperture of the counter top 22, and a movable sink 34 is removably positioned within an aperture of the counter top and can be extended therefrom as shown in FIG. 4. Further, a movable faucet 36 is similarly removably positioned within an aperture of the counter top 22 which can also be extended therefrom for remote placement relative to an individual. If desired, the present invention 10 may further comprise a horizontal panel 24 extending across the interior of the main body 12 and spaced beneath the counter top 22, and a vertical panel 26 bisecting a longitudinal length of the interior of the main body 12. The panels 24 and 26 cooperate to define a storage compartment 28, as well as to support water handling means 30 within the main body 12 for supplying water to the movable faucet 36 and for receiving waste water for storage from the sinks 32 and 34. 
     As best illustrated in FIGS. 2 through 4, it can be shown that the water handling means 30 according to the present invention 10 preferably comprises a fresh water tank 38 and a waste water tank 40 mounted within the main body 12. A battery powered demand pump 42 is positioned in fluid communication with the fresh water tank 38 for receiving fluid therefrom and maintaining a desired pressure within the water handling means 30. In other words, the demand pump preferably operates such that a drop in pressure within the water handling means 30 will cause the demand pump to automatically energize to maintain a desired minimum pressure within the water handling means 30. To this end, the demand pump may include a pressure sensor fluid communication with an output of the demand pump 42 which is in controlling electrical communication with an electric motor of the pump. If desired, a thermostatically controlled heater 44 can also be positioned into fluid communication with the demand pump so as to heat water being pumped therethrough to a desired temperature. Water pumped by the demand pump is received by a supply conduit 46 positioned into fluid communication with an output of the demand pump 42. The supply conduit 46 extends into communication with the movable faucet 36 such that water from the fresh water tank 38 is continuously supplied to the movable faucet for use during a shampooing or washing procedure. To handle waste water generated during use of the device 10, drain conduits 48 extends from the sinks 32 and 34 and into fluid communication with the waste water tank 40. By this structure, water can be dispensed by the movable faucet 36 into either of the sinks 32 and 34 during a washing procedure, whereby waste water will then gravitationally flow into the waste water tank 40. If desired, an additional and unillustrated waste water pump can be positioned into fluid communication with the drain conduits to create a vacuum or suction assisting in the disposal of the waste water into the waste water tank. 
     As shown in FIGS. 3 and 5, the water handling means 30 may further comprise a supply conduit reel 50 for storing the supply conduit when the same is unextended from the main body 12. Similarly, a drain conduit reel 52 can be included with the water handling means 30 of the invention 10 to store the drain conduit 48 coupled to the movable sink 34 during periods of non-extension thereof. As shown in FIG. 5 for the drain conduit reel 52 only, each of the conduit reels 50 and 52 is substantially similar in design and includes a spool 54 rotatably mounted upon an unillustrated axle secured within the main body 12. The drain conduit 48 extends through a center of the spool and through an unillustrated aperture therein to wind upon the spool 54. An unillustrated rotatable coupling, if desired, can be interposed between portions of the drain conduit 48 to permit ease of rotation of the spool 54 during winding of the drain conduit 48 thereonto. An unillustrated manual crank can extend from a rear of the main body 12 to permit manual reeling of the drain conduit 48 onto the spool 54. However, it is preferable that an unillustrated torsion or spiral spring be interposed between the spool and the axle supporting it so as to cause an automatic rewinding of the drain conduit 48 onto the spool. Suitable and unillustrated locking means of conventional configuration can be provided in combination with the spring for selectively locking the spool in a desired orientation so as to maintain a desired length of the drain conduit 48 off of the spool 54. 
     As shown in FIGS. 6 and 7, the movable sink 34 comprises a bottom wall 56 having a neck aperture 58 directed thereinto for accommodating a neck of an individual being shampooed or otherwise washed. A U-shaped side wall 60 extends around a portion of an outer periphery of the bottom wall and includes tapered forward portions 62 extending along laterally opposed sides of the neck aperture 58. The drain conduit 48 extends through the bottom wall 56 such that fluids within the movable sink can flow into the drain conduit for ultimate reception within the waste water tank 40. Preferably, the movable sink 34 is constructed of a substantially ductile, malleable, or deformable material permitting selective and non-resilient deformation of the movable sink 34 into a desired configuration. In other words,it is desirable for the material of the sink 34 to be deformable into a specific configuration, whereby such configuration is retained by the material. Examples of suitable materials include soft plastics, lead alloys, or other conventionally know ductile materials. By this structure, the movable sink can be placed behind a head of an individual residing within a bed and selectively deformed into a desired configuration so as to minimize water loss or escape of water from the movable sink 34. A washing procedure such as shampooing may then commence without a need for moving the patient from the bed. 
     Lastly, and as shown in FIG. 1, the linen basket 25 preferably comprises a U-shaped support bar 64 secured to the side of the main body 12. A mesh bag 66 is coupled to the U-shaped support bar 64 and depends downwardly therefrom for receiving objects such as linen. 
     In use, the portable washing cart 10 according to the present invention can be easily utilized for facilitating the washing or bathing and shampooing of an individual residing within a bed such as can be found within hospitals. 
     As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and descried in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
