| 440120500 | SELF-PROPELLED VEHICLE HAVING LAND AND WATER PROPULSION MEANS (E.G., AMPHIBIOUS VEHICLE) | 81 |
| 20080227343 | AMPHIBIOUS DRIVE SYSTEM FOR A BOAT - An improved amphibious drive system for a watercraft. The amphibious drive system features a paddled drive wheel which is operatively mounted to a drive frame. The drive frame pivots about a horizontal pivot joint. The drive wheel can thereby be raised and lowered with respect to the watercraft. In the elevated position the drive wheel is only partially submerged in the water (such that the drive wheel may operate like a paddlewheel). In the lowered position the drive is submerged more deeply in the water. The amphibious drive system also features a mount plate for attaching the amphibious drive system to the transom of the watercraft. A swing-arm frame links the drive frame to the mount plate. The swing-arm frame pivots in the horizontal direction relative to the watercraft via a vertically-oriented kingpin. This action angularly offsets the thrust from the drive wheel, thereby allowing steering. | 09-18-2008 |
| 20080227344 | AMPHIBIOUS ALL-TERRAIN VEHICLE - An amphibious, all-terrain vehicle utilizing a pair of hydrostatic pumps to independently provide power to hydraulic drive mechanisms of the left and right side of the vehicle respectively.

Using a novel hydraulic manifold assembly, the vehicle can operate in three distinct modes: wheels only, wheels and propellers, and propellers only. The hydraulic manifold assembly also allow the vehicle to by put in neutral mode for starting. The wheel motors are mounted in a pair of undercarriage assemblies that are outside of the vehicle's body and fluidly connected to the hydraulic manifold assembly thorough a hose chase that extends well above the vehicle's waterline to eliminate the potential for water to enter the body of the vehicle when operated in the water. | 09-18-2008 |

| 20100003872 | DRIVE-STEERING CONTROL SYSTEM AND VEHICLES EQUIPPED THEREWITH - A drive-steering control system suitable for off-road land and amphibious vehicles. The system includes first and second steering input levers, each operable to rotate in forward and rearward pivotal directions. A coupling mechanism converts and transmits rotation of the first steering input lever in the forward pivotal direction into rotation of the second steering input lever in the rearward pivotal direction, and vice-versa. A reducing mechanism operates to selectively reduce the propulsion outputs of first and second propulsion devices, and a converting mechanism operates to convert the rotations of the steering input levers into inputs to the reducing mechanism. Depending on the directions the steering input levers are rotated, the reducing mechanism reduces the propulsion output of either the first or second propulsion device, which causes either the lefthand or righthand side of the vehicle to travel at a lower speed and thereby turn the vehicle either left or right. | 01-07-2010 |

The vehicle includes a deployment device to deploy the elements on one side before beginning to deploy the elements on the other side of the rolling base. The elements are deployed in at least three different configurations.

| 20130078877 | MULTI-PURPOSE AMPHIBIOUS VEHICLE - When the multi-purpose amphibious vehicle moves on surfaces of any type of terrain, it runs on a rolling track by rolling friction faster than a critical speed. The multi-purpose vehicle can run very smoothly and economically with a single engine, can provide multi-terrain capability with no hesitation between surfaces of different types of terrains, and can go as fast on the surfaces of water, snow and ice as it can run on the surface of land. Journey between islands, use for arctic expeditions, higher speed entry along inland rivers, and on the other hand, operation on areas of marsh or swamp using lower ground pressure tracks are all possible with this multi-purpose amphibious vehicle. | 03-28-2013 |

| 20140057504 | AMPHIBIOUS PERSONNEL CARRIER RUNNING ON LAND AND WATER SURFACES - The purpose of an embodiment of this invention is, in order to satisfy the requirements for 21st century amphibious landing operations, to develop an amphibious personnel carrier capable of driving faster than 25 Km/hr on the surface of water, executing a seamless transition from sea to land and maneuvering with a mechanized task force for sustained operations ashore. This goal is achieved by the amphibious personnel carrier being composed of 4 front tires and two set of rear tracked belts including six tires configured in a 3×3 arrangement to which the principle of moving on the surface of water depending upon the elevation force being generated over the critical speed is applied, and an engine that can propel the vehicle to run on land and water surfaces with its own traction by the rolling friction over the critical speed. | 02-27-2014 |
| 20140302731 | STABLE HIGH-SPEED UTILITY VEHICLE - This disclosure describes a stable, high-speed utility vehicle. In an implementation, an example utility vehicle provides stable, fast transport over snow and ice. A chassis places the center of gravity of the entire vehicle low for stability during quick turns at high speed. The hull of the vehicle can float over snow or loose debris. The hull includes angular side panels that grip and grab snow when the vehicle tilts substantially to one side. The sides constitute a rail or riding surface for the vehicle to support the vehicle during sideways traverse on a steep slope. Multiple simultaneous steering mechanisms enable the vehicle to turn stably, in a tight radius, even at relatively high speeds. In an implementation, the vehicle features a 200-500 HP engine with speeds of 60 mph to transport work crews to remote utility sites. | 10-09-2014 |

A wheel segment is pivotally attached to the center wheel section about a pivot axis extending along the side of the center wheel section. The wheel segment is movable from a rolling orientation, where the outer edge of the wheel segment is aligned with an outer edge of the center wheel section such that the folding wheel takes a rolling circular shape, to a folded orientation where the wheel segment extends laterally away from the pivot axis. Two, three, or more wheel segments can be pivotally attached to corresponding sides of the center wheel section. | 02-27-2014 |

| 20160375737 | Maneuverable Platforms - 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. | 12-29-2016 |

| 20110217887 | VEHICLE DRIVE TRANSMISSION AND STEERING SYSTEM - On an amphibious ATV, a triple-differential transmission is combined a continuously-variable drive. The gearbox can be set at a low ratio, for negotiation of difficult terrain, and at a high ratio for cruising trails. The high-low shift mechanism is located upstream, in the drive train, of the forward-reverse shift mechanism. Both mechanisms are located upstream of the steer-differential and of the two wheel-differentials. Main power from the engine is passed, through the mechanisms, directly to a wheel-ring that is common to both wheel-differentials. The common wheel-ring is bearing'd, not from the gearbox housing, but from the wheel-shafts, which are themselves bearing'd into the gearbox housing. Similarly, the steer-diff-housing is bearing'd, not from the gearbox housing, but from the steer-shafts, which are themselves bearing'd from the gearbox housing, which makes for a compact, narrow, layout of the gearbox—well suited to the ATV. The steer-brake-disks are located on the steer-shafts, and are positioned outside the gearbox housing. | 09-08-2011 |
