20090050043 | DRAIN PLUG AND PORT ASSEMBLY - A drain plug apparatus for draining a container that is particularly suited for transom drains in recreational boats is shown. The apparatus has a threaded drain plug that couples with a flanged tubular drain port with upper and lower sets of threads separated by a section without threads and at least one drain hole, in one embodiment. The distal end of the drain port has a number of slits that secure and orient the drain plug at the opening of the port in an open or closed position. | 02-26-2009 |
20090260557 | ENSURING INSTALLATION OF DRAIN PLUG WHEN LAUNCHING AQUATIC VESSEL - An auxiliary strap, connected to a tie-down strap for securing a boat to a trailer, is removably anchored to a drain opening in the boat, by being connected to a tethered drain plug, or by being connected to a spring clip that extends into the drain opening. The connection of the tie-down strap to the drain opening reminds the boater to reinstall the drain plug before launching the boat. | 10-22-2009 |
20100300343 | Check Valve Boat Plug Systems - A boat plug system for automatically sealing a boat. The boat plug system is mounted in a drain hole passing through the boat's transom and includes: a cylindrical-shaped plug; a ball valve assembly removably coupled within the cylindrical-shaped plug; and further comprising a ball, a sealing ball seat component having a frustroconical shape to receive the ball when the ball valve assembly is in the sealed position, and at least one screen; and a plug cap/tool further comprising a tool head on one side for removably coupling the ball valve assembly within the cylindrical-shaped plug and an opposite side of the plug cap/tool from the tool head is for sealing the cylindrical-shaped plug. Water may flow out of the boat's drain hole, but is substantially stopped from flowing from the exterior of the boat to the interior via the drain hole. | 12-02-2010 |
20110041750 | SELF-BAILING WATERCRAFT VALVE - A valve for use in combination with a self-bailing hole of a watercraft includes a flange, a skirt, a valve member, a retention member, and a base member. The flange has a central aperture opening into a hollow interior of the skirt. The hollow interior contains the valve member, which is movable between a sealed configuration preventing fluid flow through the valve and an unsealed configuration allowing fluid flow through the valve. One end of the skirt is secured to the flange, while the other end of the skirt has an opening larger than the central aperture of the flange. The retention member prevents the valve member from exiting the hollow interior of the skirt in the unsealed configuration, while the base member is used to secure the valve within the self-bailing hole of the watercraft. | 02-24-2011 |
20110259255 | Tamper Proof Boat Drain Plug - A boat plug has external threads that mate with a boat hole housing, and an end keyed to operate the plug. In preferred embodiments the key has a first end portion that mates with the plug, and a second end portion that mates with a driver. The first end portion, and the corresponding recess in the plug, can advantageously have depths of no more than 1 cm, and more preferably no more than 5 mm. In other aspects of preferred embodiments, the first end portion comprises a recess having irregularities, and independently the second end portion comprises a nut. | 10-27-2011 |
20150075415 | Angled Drain Port with Plug - A drain plug including a first handle on an interior side of a boat and a second handle on an exterior side of the boat, allowing the drain plug to be operated from an exterior side of the boat or from the interior side of the boat. The handles are also sized to prevent passage through a drain port to prevent the drain plug from being lost. The drain port in which the drain plug is disposed may be angled to provide for clearance between the first handle of the drain plug and the hull of the boat and enable a user to easily grasp the interior handle of the drain plug to install and uninstall the drain plug by hand. | 03-19-2015 |
20220135185 | Marine Drainage Device - A drainage device for directing fluid away from a thru-hull fitting located on a hull of a vessel includes: a channel body mountable proximate to and extendable away from the hull of the vessel; a groove formed along at least a partial length of the thru-hull body; and a lip protruding from a bottom edge of the channel body at an end of the channel body that is distal from the hull of the vessel when the drainage device is mounted thereon. | 05-05-2022 |
