Patent number: 11148764Abstract: A unique watercraft that includes a plurality of flotation elements which are aligned longitudinally and fit together end to end, comprising the watercraft hull. Unlike other watercraft, it does not rely upon a low center of gravity for stability. A front flotation element pivots about an axis and this pivotal motion is used for both steering and for maintaining balance. The effective profile of the hull changes dynamically as the front flotation element is turned. These hull changes allow the operator to balance and make agile maneuvers. Equilibrium can be easily maintained in this manner when the watercraft is moving forward and when it is otherwise stationary in water. In a preferred embodiment, the watercraft is ridden like a bicycle. Balance is actively maintained by a rider who steers right and left to adjust transverse weight distribution. The riding experience feels similar to operating a conventional bicycle on land.Type: GrantFiled: January 19, 2020Date of Patent: October 19, 2021Inventors: Dennis Brown Lee Brown, Sean Clinton Richard Brown

Patent number: 5217398Abstract: A pedal operated catamaran includes a pair of side-by-side buoyant hulls, and a rigid frame releasably mounted to the hulls in one of two alternative positions, to maintain the hulls parallel to one another. The catamaran includes a propeller mounted for rotation with an elongated, longitudinal propeller drive shaft. A gear train drivably associates the propeller drive shaft and a crankshaft, for propeller rotation responsive to rotation of the crankshaft. The propeller drive shaft further is pivotally mounted to allow selective alternative latching of the propeller in a retracted position and in one of several operating positions, as controlled by a hand-operated lever. The latching mechanism allows on-the-fly adjustment of the propeller position. In the retracted position, the propeller is automatically angularly locked above the hulls, to facilitate car top carrying of the craft without disassembly.Type: GrantFiled: April 14, 1992Date of Patent: June 8, 1993Assignee: Yamaha Hatsudoki Kabushiki KaishaInventors: Abraham Meron, Masanori Sugita

Patent number: 5183422Abstract: A pedal boat for recreational use includes an inflatable ring on top of which is mounted a platform structure carrying a seat, pedals and a steering mechanism. The pedals drive a shaft mounted diametrically of the ring and carrying paddles. The steering action is effected by clutching the left or right paddles on the drive shaft.Type: GrantFiled: March 12, 1992Date of Patent: February 2, 1993Inventor: Thomas Guiboche

Patent number: 5127855Abstract: A water-borne vehicle with floats, a frame which is mounted on the floats providing a seat and a steering mechanism, and a propulsion means for propelling the vehicle in the water. The propulsion means comprises a plate which is generally parallel to the surface of the water and which is displaced up and down by a foot pedalled crank. A connecting arm is attached at one end rigidly and perpendicularly to the plate and at the opposite end to the crank. The horizontal position of the plate is maintained by an upright member which is slidably retained between rollers that maintain its upright position and is pivotally attached to the plate. As the crank is rotated, one end of the connecting arm follows a circular path, displacing the plate upward and downward. As the plate oscillates up and down, the upright member slides up and down between the rollers and maintains the horizontal position of the plate as directly below the upright member.Type: GrantFiled: November 1, 1990Date of Patent: July 7, 1992Inventor: William O. Heywood

Patent number: 5110313Abstract: A separable blade assembly for a rubber raft, which can be easily disassembled and conveniently carried, including two blade members, two rod members, and a bolt member. The two blade members can be associated to form a blade assembly and the two rod members can be inserted through central holes of the blade members and connected by the bolt member for driving the blade assembly. When mounted on a rubber raft, one can step on two pedals of the rod members to consequently rotate the blade assembly and move the raft forward.Type: GrantFiled: September 25, 1989Date of Patent: May 5, 1992Inventor: Tsai J. Po

Patent number: 5088944Abstract: A collapsible water bike includes a plurality of assemblies which are interconnectable using connecting assemblies that are easily locked and unlocked. The bike is driven by a pedal assembly that is operatively connected to a propeller and is steered by handlebars that are connected to a rudder.Type: GrantFiled: November 5, 1990Date of Patent: February 18, 1992Inventor: Simon Kats

Patent number: 5058522Abstract: A portable personal floatation device for water sports such as fishing and the like is constructed of a light material such as styrofoam and has a main cross panel with an opening for a user to fit through so the floatation device surrounds the user. The device is designed to be easily accessible for the user, with a door provided on a side panel. The central opening in the main panel of the device accommodates the occupant to carry the device and wade into the water, and as the device begins to float, the occupant may sit on the main panel of the device.Type: GrantFiled: May 21, 1990Date of Patent: October 22, 1991Inventor: Martin G. Bauer

Patent number: 5030145Abstract: A manually operable unit having a single handle for driving, steering and tilting a boat propeller. The crank handle, when turned, drives the propeller through bevel gearing. A vertical sleeve surrounding a vertical drive shaft has an offset U-shaped portion terminating in a sleeve serving as a bearing for the crank handle. Pushing the crank handle against the bearing rotates the vertical sleeve which mounts the propeller, therefore steering the propeller. Pulling of the handle will tilt the vertical sleeve with respect to a mounting C-clamp to pivotally raise the propeller.Type: GrantFiled: July 11, 1990Date of Patent: July 9, 1991Inventor: Robert Chase
