Portable washing device

A washing apparatus for holding a supply of a washing liquid dispensed from a pressurized source, said washing apparatus comprising:

• a portable elongated wand having first and second ends, said wand having an outer surface forming a handle means to facilitate manual gripping and manipulation, said wand having an internal cavity extending substantially from said first to said second ends;
• an expandable reservoir for receipt of a supply of said washing liquid, said reservoir being disposed within said cavity;
• reservoir biasing means for applying a predetermined pressure on the washing liquid within said expandable reservoir;
• an inlet valve mounted on said first end of said wand and communicating with said expandable reservoir within said cavity;
• a nozzle mounted on said first end of said wand and communicating with said reservoir;
• a discharge valve between the reservoir and the nozzle;
• manual operating means mounted on said wand for selectively opening and closing said discharge valve;
• an inlet valve mounted on said first end of said wand, said inlet valve communicating with said expandable reservoir;
• a charging stand independent of said wand;
• said charging stand having a coupling for connection to the pressurized source of washing liquid and a filling valve, a fluid connection between said coupling and said filling valve, said filling valve and said inlet valve having separate coupling parts interengagable in interfacing relationship to establish a fluid flow path for pressurized washing liquid for filling said reservoir, said reservoir biasing means being yieldably movable to a biasing position for applying said predetermined biasing pressure to the washing liquid in response to a filling of said reservoir, said predetermined pressure being sufficient to expel the washing liquid through the discharge valve and the nozzle upon operation of said manual operating means;
• and
• valve biasing means biasing the filling and inlet valves to a closed position when the coupling parts are separated and to an open position for filling said reservoir when said coupling parts are interengaged.

A washing apparatus containing a supply of a washing liquid dispensed from a pressurized source of the washing liquid, said washing apparatus comprising:

• a portable elongated tubular wand having first and second ends, a handle means and an internal reservoir;
• a manifold mounted on said first end of said elongated wand;
• an inlet tube communicating with said manifold;
• a nozzle communicating with said manifold;
• a manifold port communicating between said manifold and said reservoir;
• an inlet valve interposed between said inlet tube and said manifold;
• a discharge valve interposed between said nozzle and said manifold, said discharge valve having valve biasing means for biasing said discharge valve in a closed position, said discharge valve further having means for manually opening said discharge valve;
• a charging stand for filling said reservoir with the washing liquid from the pressurized source, said charging stand being connected to the pressurized source and having a filling tube interengagable with said inlet tube, said filling tube having a filling valve interposed between said filling tube and said pressurized source, said inlet valve and said filling valve each having means for opening said valves simultaneously when said inlet tube is forcibly interengaged with said filling tube, said inlet valve and said filling valve each further having means for closing said valves when said inlet tube is disengaged from said filling tube and said wand is separated from said stand;
• and
• biasing means for pressurizing the supply of washing liquid held in said reservoir, said biasing means being mounted within said wand and being biased to a pressurized status by the pressure of the pressurized source when said reservoir is filled.
