AI Technical Summary

Benefits of technology

The present invention provides a floatation device that can easily be mounted without being stabilized, which can be difficult when trying to mount a non-stabilized device. The device also provides ballast almost immediately upon deployment in water, reducing the risk of overturning due to wind and waves. Additionally, the device provides ballast without adding extra weight to depend on water-retaining chambers.

Problems solved by technology

Rescue rafts use either no ballast system or an ineffective, unweighted water-retaining chamber.

Embodiment Construction

[0011]The invention includes any floatation device for which ballast is provided by sponge, usually but not necessarily compressed synthetic sponge, contained in one or more permeable enclosures, which enclosures in turn are secured to the underside of the device. As used in this application, “floatation device” or “floatation element” refers to any item capable of providing buoyancy, such as, for instance, inflated synthetic rubber.

[0012]Referring now to the drawings, FIG. 1 illustrates a suitable placement of permeable enclosures 14 and 16 of a sponge ballast system 10 according to the present invention, said enclosures indicated with shading, said enclosures being secured to the underside 13 of a floatation device 12 having at least one inflatable element 30, a forward portion 31 with a bow 32, a rear portion 33 with a stern 34, a length extending between the bow 32 and the stern 34, a width that is less than the length, and a floor 36 including inflatable chambers 38. FIG. 2 ill...

Abstract

A floatation device of any size or shape stabilized by a ballast system comprised of sponge contained in permeable enclosures, which enclosures in turn are secured to the underside of the device, which sponge, upon contact with water, rapidly absorbs such water and provides prompt, sufficient ballast.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is a continuation of U.S. patent application Ser. No. 12 / 932,022 filed Feb. 16, 2011 and claims the benefit of U.S. Provisional Application No. 61 / 338,349 filed by Stanton Dennis Terrell and Cynthia Mary Shell-Terrell and awarded a filing date of Feb. 18, 2010.BACKGROUND OF THE INVENTION[0002]The present invention relates generally to floatation devices and more specifically, as to certain embodiments, to stabilized rescue rafts.[0003]Stabilized survival rafts are well known. For ballast, these rafts rely on a depending, weighted, water-enclosure system. These water-enclosure systems are designed in one of three ways: (one) several depending enclosures along the underside of a raft; (two) one large, depending enclosure under the center of a raft; or (three) several peripheral depending enclosures. These enclosures are sometimes referred to as “water-retaining chambers.” The several depending enclosures is seen in U.S. Pat....
