Human Propulsion System

摘要

A human-propulsion-system utilizing a telescoping arm lever assembly and an optional pedal assembly to be adapted to or incorporated into other mechanisms including, but not limited to, wheelchairs and vehicles. The arm lever assembly and the pedal assembly can be utilized in combination or independently further being operatively connected to a converter that utilizes gears and one-way clutches to receive the reciprocal movements of the arm lever assembly and the rotational movements of the pedal assembly converting them into a combined unidirectional output. The arm lever assembly utilizes a slide mechanism that correspondingly moves the load end closer to the fulcrum point when the arm lever assembly is extended and correspondingly moves the load end farther away from the fulcrum point when the arm lever assembly is retracted offering a range of adjustable leverages. The arm lever assembly is further rotated left or right to provide a means of (steering) control.

主权项

1. A human-propulsion-system having an arm lever assembly with a force end that is telescoping, a fulcrum point, and a load point that correspondingly changes distance from the fulcrum point when the force end is extended or retracted comprising:
an arm lever having at least two telescoping sections wherein, one is a lower section that telescopically supports an upper section while maintaining rotational unity, further the upper section provides the force end and is graspable by at least one hand of an operator; a reciprocating member supports the lower section rotationally free and further provides the fulcrum point to allow the operator to reciprocate the arm lever assembly; a sliding mechanism, that provides the load point, is linearly supported by the reciprocating member and further connected to the telescoping action of the upper section; a controller operatively connecting the rotational movements of the arm lever assembly to a controlled (steerable) assembly; a support mechanism comprising: a pivot support that pivotally supports the arm lever assembly at the fulcrum point; a frame attached to the pivot support; a seat supported by the frame to support the operator; and a leg member attached to the frame forward of the seat that is utilized by the operator's legs; and a converter, having an input end and an output end, wherein the input end acts upon the reciprocating movements of the arm lever assembly and converts them into a unidirectional rotation of the output end to be utilized to motivate a function of the supports mechanism, further the converter is operatively supported by the frame.
