Abstract
A human powered watercraft or land vehicle is described herein. A watercraft or land vehicle may have two pedals that reciprocated are in a linear or slightly curved trajectory but not a circular motion. As the two pedals are reciprocated, an output shaft is rotated in either a clockwise or counterclockwise direction when the left pedal is pushed forward or when the right pedal is pushed forward. The output shaft may be connected to a propeller of a watercraft or a land vehicle so as to propel the watercraft or land vehicle forward. The output shaft may receive rotational input through two gears mounted to the output shaft with one-way bearings that enable the output shaft to rotate in the same direction regardless of whether the left pedal or the right pedal is being pushed forward.
Claims1
A human powered vehicle operative to rotate a propeller or rotate a wheel by reciprocating left and right pedals, the vehicle comprising:
- a frame;
- a left pedal operative to reciprocate linearly or through a partial curved trajectory;
- a right pedal operative to reciprocate linearly or through a partial curved trajectory;
- a left rack attached to the left pedal so that reciprocating the left pedal reciprocates the left rack;
- a right rack attached to the right pedal so that reciprocating the right pedal reciprocates the right rack;
- a left shaft;
- a right shaft;
- a left pinion engaged to the left rack so that the left pinion reciprocates with the left rack, the left pinion attached to the left shaft;
- a right pinion engaged to the right rack so that the right pinion reciprocates with the right rack, the right pinion attached to the right shaft;
- a left beveled gear attached to the left shaft;
- a right beveled gear attached to the right shaft;
- a main shaft;
- an upper one way bearing;
- an upper beveled gear attached to the main shaft with the upper one way bearing;
- a lower one way bearing;
- a lower beveled gear attached to the main shaft with the lower one way bearing;
- a transmission box attached to the frame, the transmission box having an input shaft and an output shaft, the input shaft operative to rotate the output shaft, the main shaft being coupled to the input shaft;
- and
- the propeller or the wheel attached to the output shaft.
