Abstract

A hand held an portable pump has a housing with an inlet on the bottom and an outlet on its side. A central tube extends up from the housing and has a bulb attached at its end. An inlet gate is positioned proximate the inlet to operate between a closed position in which the flow of liquid there through is inhibited and an open position in which liquid may flow through the inlet. The outlet has an outlet gate that is positioned to inhibit the flow of liquid into the housing in its closed position and to permit the flow of liquid out of the housing and into a discharge tube in the open position. The bulb is operated between an at rest position and a deflected or compressed position to urge fluid into and out of the bulb and in turn draw liquid through the inlet into the housing and to urge the liquid out of the outlet and into the discharge tube.

Claims4

Dependent claims

A portable toilet tank and bowl drainage device, said device comprising:

a housing having a first end for positioning proximate a submerged surface and a second end spaced from said first end, said housing having an inlet proximate said first end configured to receive liquid positioned on said submerged surface and an outlet configured to discharge liquid received from said inlet;
a hand pumping device in communication with said housing, said hand pumping device being operable by a user to urge fluids including said liquid into and out of said housing;
an inlet gate mounted within said housing and proximate said inlet, said inlet gate being operable between an open position to allow liquid to flow into said housing and a closed position to inhibit the flow of liquid out of said inlet;
an outlet gate mounted within said housing and proximate said outlet, said outlet gate being operable between an open position to allow liquid to out from said housing and a closed position to inhibit the flow of liquid into said housing;
and
a discharge tube having a first end connected to said outlet and a second end spaced away from said housing.
