Arm powered cycle/vehicle suitable for paraplegics

摘要

A human powered cycle/vehicle utilizes a reciprocating arcuate handlebar motion to operate a double acting propulsion mechanism which imparts constantly proportional input versus output motion to its surface engaging propulsion wheel(s). The propulsion mechanism contains a mechanism (4) which causes both backward and forward motions of a set of handlebars (1) to propel the machine forward. The propulsion mechanism may comprise a chain, or a belt, cord or gears. A bevel gear and shaft version is also disclosed (figure 11). A drive-train clutch (52) may be included which enables the propulsion mechanism to be disengaged thus allowing the cycle/vehicle to be reversed and or moved (pushed) in either direction via its' surface engaging wheel(s) in isolation to the propulsion mechanism. A steering mechanism may also be attached to the handlebars (1).
