Abstract:
A rack-driven seated handcycle is a semi-recumbent style two, three, or four wheeled human powered cycle that uses a linearly designed toothed rack with teeth located on the topside and bottom side of the rack, and a gear that meshes with the top teeth and a gear that meshes with the bottom teeth, at least one ratchet mechanism, and a chain coupling the upper and lower gears with the drive wheel which may be located in front or back of the rider. The rider pushes and pulls the “handlebars” forward and rearward to pull the rack back and forth in relation to the pinions above and below the toothed rack to drive chain(s) to propel the cycle forward. Each forward and each rearward stroke may constitute a power stroke to propel the cycle. A plurality of gear speeds is able to in select a lever ratio for each of the forward and the rearward strokes.

Claim (Index 1):
A rack-driven seated handcycle comprising:\n a. at least two wheels adapted to support and mobilize said rack-driven seated handcycle, said at least two wheels coupled to a frame, said frame comprising a beam; b. a seat adapted to support a user, said seat mounted upon said beam; c. at least one handle fixedly coupled to a first rack, said at least one handle adapted to be grasped by at least one hand of the user; d. first rack comprising a first longitudinal side, said first longitudinal side comprising a first set of teeth; e. a first axle mounted to said frame, said axle comprising a first pinion mounted to said first axle, said first pinion adapted for communication with said first set of teeth;\n wherein said first axle is turned via the longitudinal movement of said first rack; \n f. a tint sprocket mounted to said first axle, said first sprocket coupled to a first chain, said first chain coupled to a first ratchet; g. a second sprocket coupled to a second chain, said second chain coupled to a second ratchet; h. wherein said first and second ratchets coupled to at least one of said at least two wheels, said first and second ratchets arranged for rotation opposite one another for provision of drive power to at least one of said at least two wheels.
