One-way self-closing drain plug apparatus
First Claim
1. A one-way self-closing drain plug assembly for a boat comprising:
- a hollow body assembly having an inlet and an outlet;
at least two chambers being located in said hollow body assembly;
a first chamber houses a valve assembly including a manual mechanism for opening and closing said valve assembly, wherein said manual mechanism includes a handle coupled to said valve assembly for opening and closing thereof, and said handle is shaped into a paddle that, when in the open position, is disposed perpendicular to the longitudinal axis of said boat, whereby said valve assembly is automatically closed when left open and when exposed to moving fluid caused by movement of said boat;
a second chamber houses a safety device; and
said safety device enables fluid flow to occur in one direction and prevent fluid flow from an opposite direction by blocking access to said first chamber regardless of the position of said valve assembly.

Abstract
The present invention is a drain plug apparatus designed and configured to remain in the drain hole of a conventional pleasure water vessel, regardless of whether the vessel is in or out of the water. This drain plug apparatus includes a body assembly having at least two chambers. One chamber will house a shut-off valve for enabling the boater to open or close the drain plug apparatus. This will render water to escape or prevent entrance to the boat, respectively. A safety assembly is included in the second and each subsequent chamber. The safety assembly will prevent water passage into the water vessel should the user forget to close the drain plug assembly, prior to placing the boat in water.
