Abstract
Abstract A portable sink unit particularly intended for use by campers comprises a water tank and a water basin supported by a basinsupporting frame carried at the upper ends of a number of upstanding support rods slidably mounted within bores extending downwardly in the sidewalls of the water tank and securable in any desired vertical position. When not in use, the aforementioned supporting frame is disposed above the water basin with the upstanding rods extending through openings in a peripheral flange of the basin so as to hold the basin against the top surface of the tank. The unit may also comprise side basins which can function as dish drainers or rinsing bowls and these side basins are usefully supported by arms pivotally mounted on the upstanding rods for movement between laterally extending supporting positions and retracted stowed positions. The side basins can be stowed in nesting disposition with the water basing against the top surface of the tank. The water tank also usefully comprises a built in electrically operated water pump and compartments or recesses are usefully provided in the walls of the tank for housing the various water flow conduits or pipes and the electrical cord for the pump when the unit is not in use.
