Aerial location self-actuating emergency sea surface marker for capsized vessels
First Claim
1. An emergency location marker system for capsized vessels comprising:
- a location marker container and bracket for securing the container to an exposed or outside surface of a vessel;
an inflatable sea surface location marker means formed in a relatively large surface area flat configuration for floating on the surface of the sea and blanketing a sufficient surface area of the sea for high visibility location by aerial search, said location marker means having at least one flexible joint thereacross permitting said location marker means to flex in response to wave motion while adhering to the sea surface;
a source of compressed gas coupled to the inflatable sea surface location marker means, said location marker means and source of compressed gas being housed in the container;
and a sensor valve means coupled between the source of compressed gas and location marker means responsive to one of water and pressure within the container caused by a capsized condition of the vessel to leave air from the source of compressed gas for inflating the sea surface location marker means;
said container comprising separable segments constructed with at least one break seam for opening in response to inflation of the location marker means for releasing the inflated location marker means;
and a line stored in the container, said line being secured at one end to the vessel and at the other end to the location marker means.

Abstract
An emergency location marker system for capsized vessels is housed in an emergency location marker canister or container (10) secured by a bracket (22) to an exposed or outside surface of the vessel (60). An inflatable aerial location marker (40) is deflated and folded in the small space of the canister. The aerial location marker is formed to provide upon inflation a relatively large surface area flat configuration to blanket a sufficient area of the sea surface for high visibility. The high visibility sea surface area blanketing marker (40) is formed with at least one flexible joint (41) for responding flexibly to wave motion while adhering to the sea surface. The sea surface area marker may be in a flat circular configuration, for example six feet in diameter and formed with a high visibility color. Flexible joints (41) along intersecting diameters permit flexing of the flat circular configuration marker in response to waves from all directions. A source of compressed air or gas such as a compressed air cylinder (36) is also housed in the canister (10) coupled to the inflatable marker bladder. A valve (38) on the compressed air cylinder or cartridge is activated by water immersion to inflate the bladder. The canister is comprised of separable segments constructed with break seams (32a,34) for opening or exploding in response to inflation of the location marker for releasing the inflating bladder. The canister also incorporates a feed line (44) for example on a rotating spool (26). One end (46) of the line is secured to the vessel and the other end to the location marker.

8. An emergency location marker system for vessels lost at sea below the water surface comprising:
-
an inflatable sea surface location marker constructed to form upon inflation a relatively large surface area flat configuration for blanketing a sufficient sea surface area for high visibility location by aerial search, said inflatable sea surface location marker being formed with at least one flexible joint for permitting said marker to flex in response to wave motion while adhering to the sea surface; a location marker system container for storing the sea surface location marker in deflated folded form in a relatively small volume and bracket means for securing the container to an outside surface of a vessel; a source of compressed gas and a sensor valve means for coupling the source of compressed gas to the inflatable sea surface location marker in the container, said sensor valve means being responsive to one of water and pressure in the container caused by a capsized condition of the vessel to inflate the location marker from the source of compressed gas; said container comprising separable segments constructed with at least one break seam for breaking open in response to inflation of the location marker for releasing the inflated location marker; and a line stored in the container secured at one end to the vessel and at the other end to the location marker. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
