摘要:
The overboard drive mechanism for boats propulsion and maneuverability on water of the present invention, is manually, solar, and engine powered. The device when connected to the manual system (cycling means), is designed for single cycling and double cycling system. The device also is designed with double gearbox, overboard gearbox and aero gearbox or submersible gearbox which rotates in the overboard gearbox to turn the boat while the propeller is running in water. The maximum rotation of the submersible gearbox/rudder is 360 degrees. The device is portable and is also designed to propel the boat on water by rotating the propeller up in the Air on a high speed. The device can also be used to propel the boat forward and backwards using only steering wheel without reverse gear. The principle use of the present invention is for boat racing, transport, patrol, leisure, rescue during floods and environmental purposes.
摘要:
A paddle device. First and second paddle assemblies each have a paddle blade extending from a paddle end of a paddle arm so that the paddle structures each have a paddle blade end and a paddle arm end. A hand crankable crank shaft arrangement have a center and first and second ends and having handle segments. The paddle arm end of the first paddle structure is coupled to the first end of the crank shaft arrangement and the paddle arm end of the second paddle structure is coupled to the second end of the crank shaft arrangement. First and second handle grips are rotatably coupled to the crank shaft arrangement so as to permit the crank shaft arrangement to rotate with respect to the first and second handle grips when the crankshaft arrangement is cranked. This abstract is not to be considered limiting.

The present invention relates to a bicycle for water and land including: a first floating means, which is provided on and rotates together with a front wheel frame rotating in conjunction with handlebars, for unfolding on both sides by means of buoyancy to float the front wheel frame when entering water; a second floating means, which is provided on a rear wheel frame, for unfolding on both sides by means of buoyancy to float the rear wheel frame when entering water; and propellers, which are provided on a plurality of spokes installed on the rear wheel frame so that the surfaces face the direction in which the rear wheel rotates, for generating propelling force in water.
摘要:
Set of pieces in kit form for the quick assembly of boats, optionally propelled by pedals and paddlewheels, configurable for one or some passengers, constituted by a basic structure with several crossbars placed traversely in relation to the direction of advance of the boat, that are secured to at least two main longitudinal floats whose number is equal to the number of passengers plus one. All the necessary elements for propulsion and control of the pedal boat and for passenger's accommodation are placed between each two adjacent floats. The basic structure previously cited gets rigidity with two longitudinal bars or plates that ends in two traverse segments each one. The longitudinal section of these longitudinal bars or plates is secured to the traverse crossbars of the boat and their respective traverse sections are fixed to one of the floats. The propulsion and control elements of the boat can be joined and assembled side by side serially in a number equal to the number of passengers of the boat.
摘要:
An improved muscle propelled boat or watercraft like construction is characterized in that said construction comprises a hull (2) including a propelling assembly (5), which is driven by the combined action of the arms and legs of the user, the propelling assembly comprising a gear transmission (50).

摘要:
A device for insertion in watercraft including propulsion means comprising a pair of flappers which oscillate through an arcuate path in a transverse direction with respect to the central longitudinal dimension of the watercraft. As input force is applied, the flappers twist to form an angle of attack for providing forward thrust. The means for applying propulsive force includes a pair of pedals, and further includes pedal cranks operatively associated with the propulsion means, the fore ends of the pedals being pivotally attached to a fixed point.
摘要:
A device including propulsion means extending below the water line comprising a pair of flexible fins each adapted to oscillate through an arcuate path in a generally transverse direction with respect to the central longitudinal dimension of said watercraft, and means operatively associated with said propulsion means for applying input force to said propulsion means whereby as input force is applied said flexible fins can twist to form an angle of attack for providing forward thrust with respect to the longitudinal dimension of the watercraft while moving in both directions along said arcuate path, each said fin being carried at its upper trailing edge by a fixed pivot and at its upper leading edge by a retainer which is normally engaged while being disengageable when said leading edge strikes a resistance element allowing said fin to pivot aft to clear the resistance element and re-engageable as the fin rotates forward and resumes producing thrust.
