Maneuverable Platforms

Abstract

A maneuverable platform capable of operating on both fluid bodies (e.g., lakes, rivers, oceans, etc. in either liquid or frozen form) and land is provided. The platform has an above water portion formed of one or more sections onto discrete sections of which are positioned a number of buoyant propulsion members configured to support the above water portion and engage a fluid body or the ground to collectively provide support, propulsion and steering for the platform. The buoyant propulsion members are configured such that they provide buoyancy to the platform when the platform is at rest and lift when the platform reaches a specified hydrodynamic speed such that the platform planes atop the fluid of the fluid body during operation. The maneuverable platform, including the above water portion and the buoyant propulsion members, may be modular such that the platform may be split into sections of predetermined configuration to operate independently.

What is claimed is: 
     
         1 . A maneuverable platform comprising:
 a platform body defining a generally horizontal plane, the platform body being formed of at least one platform portion;   a plurality of buoyant propulsion members disposed on the underside of the platform body, the plurality of buoyant propulsion members comprising at least one buoyant wheel each, each of the buoyant wheels comprising a cylindrical toothed body rotatable about the longitudinal axis of the cylindrical toothed body;   wherein the buoyant propulsion members are rotatably interconnected to the platform about a vertical axis orthogonal to the longitudinal axis of the cylindrical toothed body;   wherein the buoyant wheels are arranged in relation to the platform to provide rotational stability to the platform; and   wherein the buoyant wheels are sufficiently buoyant such that they provide sufficient buoyant upthrust to the platform when at rest to float the platform atop a fluid body, and such that they provide dynamic buoyant lift greater than the buoyant upthrust to the platform when in motion.   
     
     
         2 . The maneuverable platform of  claim 1 , wherein at least 66% of the radius of the buoyant wheels are disposed above the waterline. 
     
     
         3 . The maneuverable platform of  claim 1 , wherein the teeth of the cylindrical toothed body are formed of right-angles. 
     
     
         4 . The maneuverable platform of  claim 1 , wherein the tangent of the outer circumference of the wheels to the surface of the water forms an angle of 45 degrees or less. 
     
     
         5 . The maneuverable platform of  claim 1 , wherein the teeth contact the water at an angle within 10 degrees of parallel with the mean surface of the water. 
     
     
         6 . The maneuverable platform of  claim 1 , wherein the teeth contact the water at an angle within 5 degrees of parallel with the mean surface of the water. 
     
     
         7 . The maneuverable platform of  claim 1 , further comprising a height regulator disposed between the at least one buoyant propulsion member and the platform such that at least the buoyant wheels are movable along a vertical axis orthogonal to the horizontal plane of the platform. 
     
     
         8 . The maneuverable platform of  claim 7 , wherein the height regulator comprises at least two vertically movable elements interconnected on either end of the cylindrical body of the buoyant wheel such that the two ends of the cylindrical body are independently movable along a vertical axis orthogonal to the horizontal plane of the platform. 
     
     
         9 . The maneuverable platform of  claim 7 , wherein the height regulator comprises at a single vertically movable element interconnected to the cylindrical body of the buoyant wheel. 
     
     
         10 . The maneuverable platform of  claim 1 , wherein a plurality of the buoyant wheels are rotatably interconnected to an interconnecting frame that is rotatably interconnected to the platform. 
     
     
         11 . The maneuverable platform of  claim 9 , wherein four buoyant wheels are interconnected to the interconnecting frame. 
     
     
         12 . The maneuverable platform of  claim 1 , comprising a plurality of detachably interconnected platform portions, wherein each platform portion comprises at least one buoyant propulsion member. 
     
     
         13 . The maneuverable platform of  claim 12 , wherein the plurality of detachably interconnected platform portions may be engaged and disengaged relative to each other in at least two configurations. 
     
     
         14 . The maneuverable platform of  claim 12 , wherein the each platform can be detachably interconnected to each other platform on all sides. 
     
     
         15 . The maneuverable platform of  claim 1 , wherein the platform is maneuverable over at least both fluid body and solid ground. 
     
     
         16 . The maneuverable platform of  claim 1 , wherein each of the wheels is coated with a hydrophobic material. 
     
     
         17 . The maneuverable platform of  claim 1 , further comprising at least one independently rotatable roller disposed on either side of each of the buoyant wheels such that rotation of the buoyant wheel causes rotation of the rollers. 
     
     
         18 . The maneuverable platform of  claim 17 , wherein the rollers comprise cylindrical toothed bodies such that they cooperatively engage the toothed bodies of the buoyant wheels. 
     
     
         19 . The maneuverable platform of  claim 1 , further comprising at least one motor mechanically engaged with each of the buoyant wheels to provide motive force thereto. 
     
     
         20 . The maneuverable platform of  claim 19 , wherein each of the buoyant wheels is driven by a separate motor.
