Amphibious vehicle with improved cleat design

A tracked vehicle having at least one endless drive track comprised of endless chains and multiple spaced, separate and distinct track cleats, at least one of said track cleats comprising a stiff body, a chamber formed within said body and means for preventing entry or transmission of foreign materials including fluids such as liquids or gas into or through said chamber.

A separate and distinct cleat comprising a stiff metal body, a chamber formed within said body, and means for preventing entry or transmission of foreign materials including fluids such as liquids or gas into or through said chamber.

An amphibious vehicle having a pair of elongated pontoons held substantially parallel by spaced beams, each pontoon enveloped by an endless drive track powered by a drive means, said endless drive track comprised of drive chains and track cleats, said cleats having a base, top, and two sides forming a chamber having opposing open ends and means for sealing said open ends, said means for sealing including means to prevent the transmission of fluids such as gas or liquids into or through said chamber.

An amphibious vehicle having at least one pontoon, each pontoon enveloped by an endless drive track powered by a drive means, said drive track comprised of endless chains and track cleats, at least two of said cleats disposed as a pair, each cleat in said pair having a base, a top, a side normal to and disposed between said base and top, and a sloped side angled to and disposed between said base and side, an adjacent angle between said base and side and a spaced angle between said base and sloped side, said adjacent angles and spaced angles in each pair of cleats being substantially equivalent.

A tracked vehicle having at least one endless drive track comprised of endless chains and multiple, spaced, separate and distinct track cleats, at least one of said track cleats comprising a stiff metal body, a chamber formed within said body, said chamber being filled with a plastic material to exclude the entry or transmission of foreign materials including fluids such as liquids or gas into or through said chamber.

An amphibious vehicle having at least one pontoon, each pontoon enveloped by an endless drive track powered by a drive means, said endless drive track comprised of endless chains and multiple, spaced, separate and distinct track cleats, at least one of said cleats comprising a body, a chamber formed within said body, and said chamber being filled with a closed cell material to exclude the entry or transmission of foreign materials including fluids such as liquids or gas into or through the chamber.
