Benefits of technology

[0004] Another object is to provide such portable bilge pumps operated by rechargeable battery power, minimizing exhausting repetitive arm movement or leg movement, which can be extremely tiring to users.

Problems solved by technology

If permanently installed, they can become clogged by entrained objects adrift in the bilge, they draw current from the vessel's batteries and may discharge them more than is desirable.
If they are “portable” bilge pumps, they are often heavy and clumsy, difficult to keep in the desired operating position, and they demand the user's arm or leg movements over long periods of time.
This exhausts the user unless additional crew members are available to operate such pumps by taking turns at pumping.

Embodiment Construction

[0020] The principal components which are combined to produce the portable bilge pumps of this invention are clearly shown in the Figures, where the elongated intake conduit 10 has a distal end 11 on which an electric bilge pump 12 is operatively mounted.

[0021] Conduit 10 is preferably a rigid hollow tube and has a proximal end 13 where an ergonomically comfortable hand-grip 14 is positioned, to which a detachable battery case 16 enclosing a rechargeable battery 17 is mounted, and connected by suitable electrical conductors to bilge pump 12. A discharge tube 18 forming a protruding extension of conduit 10 beyond hand grip 14 provides an anchor collar 19 to which the proximal end of a flexible discharge hose 21 can be solidly anchored, either by a standard garden hose coupling 22, or by a screw-type expandable and contractible hose clamp 23, preferably formed of stainless steel.

[0022] A stand-off form of hand-grip 14 is shown in FIGS. 1-4, provided with a short protruding stand-off...

Abstract

A manually portable bilge pump having a motor powered by a rechargeable battery, enclosed in a detachable battery housing, has an intake conduit extending downward to the deepest region of a vessel's bilge and a discharge conduit preferably extending overboard or to the galley sink for delivering pumped bilge water outside the vessel.

Description

FIELD OF THE INVENTION [0001] The manually portable bilge pumps of this invention fill an important need in the marine equipment field. They are light in weight, convenient to deploy and maneuver manually, and adaptable to perform many different roles in the pumping of different vessels' bilges, ranging from sailboats, cabin cruisers and open launches up to larger vessels. BACKGROUND OF THE INVENTION [0002] Bilge pumps for small boats and pleasure boats of all kinds have exhibited many disadvantages. If permanently installed, they can become clogged by entrained objects adrift in the bilge, they draw current from the vessel's batteries and may discharge them more than is desirable. If they are “portable” bilge pumps, they are often heavy and clumsy, difficult to keep in the desired operating position, and they demand the user's arm or leg movements over long periods of time. This exhausts the user unless additional crew members are available to operate such pumps by taking turns at ...
