Abstract
Abstract An amphibious vehicle is disclosed which is capable of supporting a permanent installation, such as a cabin, in all modes of travel. The vehicle comprises a central platform having a pair of retractable wheels mounted below to support the vehicle in a land travel mode. The platform further includes a plurality of lateral tubes intermittently spaced below for receiving a plurality of telescoping beams. These beams are adapted to telescope out of both sides of the platform in cantilevered positions to support a quantity of floor panels. The floor panels are adapted to be pivoted into a vertical stowed position when the beams are fully retracted into the tubes. In the stowed position, the floor panels are located on the sides of the platform to still provide sufficient space on the platform for supporting a permanent installation. A plurality of pontoons are securely mounted below the central platform and the floor panels to support the vehicles in water. A marine motor and propeller combination is also mounted below the platform to drive the vehicle in water.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
266 words
An amphibious vehicle which is convertible into a vehicledrawn trailer or a sea-going vessel, said vehicle comprising: a central platform having a pair of retractable wheels mounted thereon for supporting the vehicle as a trailer and a plurality of elongated storage containers intermittently spaced and mounted to the central platform, said platform further having at least one central floatable pontoon mounted below for supporting the vehicle as a sea-going vessel; a plurality of elongated support members telescopically supported in said elongated storage containers, said support members being movable to retract within said storage containers in a stowed position, and to extend out from said storage containers in a cantilevered position; a pair of side floatable pontoons, one mounted respectively on each side of the central pontoon, each side pontoon connected to and movable with respective support members, said respective support members of one side are staggered with respect to said support members of said other side; a plurality of floor panels pivotally connected to said elongated support members, said floor panels adapted to lie on said support members in a horizontal position when said support members are extended to form a floor, said floor panels also adapted to be stowed in a vertical position adjacent the side of said central portion to enable the central platform to have sufficient space to support a permanent installation at all times, and jack means on each side of the central platform for moving the elongated support members including a pair of relatively movable jack members connected to at least one of said elongated support members for moving the same.
Claim 2
Dependent Claim
266 words
An amphibious vehicle which is convertible into a vehicledrawn trailer or a sea-going vessel, said vehicle comprising: a central platform having a pair of retractable wheels mounted thereon for supporting the vehicle as a trailer and a plurality of elongated storage containers intermittently spaced and mounted to the central platform, said platform further having at least one central floatable pontoon mounted below for supporting the vehicle as a sea-going vessel; a plurality of elongated support members telescopically supported in said elongated storage containers, said support members being movable to retract within said storage containers in a stowed position, and to extend out from said storage containers in a cantilevered position; a pair of side floatable pontoons, one mounted respectively on each side of the central pontoon, each side pontoon connected to and movable with respective support members, said respective support members of one side are staggered with respect to said support members of said other side; a plurality of floor panels pivotally connected to said elongated support members, said floor panels adapted to lie on said support members in a horizontal position when said support members are extended to form a floor, said floor panels also adapted to be stowed in a vertical position adjacent the side of said central portion to enable the central platform to have sufficient space to support a permanent installation at all times, and jack means on each side of the central platform for moving the elongated support members including a pair of relatively movable jack members connected to at least one of said elongated support members for moving the same.
Claim 3
Dependent Claim
101 words
The invention of claim 1 where said jack means further includes: a lead screw journaled beneath said platform, said lead screw having a left handed threaded section and a right hand threaded section; one end of each jack member being threadedly connected to a respective threaded section of said lead screw, the other ends of said jack members being pivotally connected together with one of said support members, whereby rotation of said lead screw either moves the one ends of the jack members together or apart to cause the connected ends to be either drawn toward or away from said platform.
Claim 4
Dependent Claim
18 words
The invention of claim 1 wherein said support members are integrally interconnected to be movable as a unit.
Claim 5
Dependent Claim
32 words
The invention of claim 1 wherein each support member further includes a first and second group of elongated beams, the second group of beams telescoped within the first group of elongated beams.
Claim 6
Dependent Claim
36 words
The invention of claim 1 wherein each of said jack means further includes: at least one lead screw connected to said support member, said lead screw having a left handed section and a right handed section.
