Abstract
A pump handle system includes a pump handle and a main shaft. The pump handle is operable to radially pivot from a starting position in a first pivot direction and back to the starting position in a second pivot direction opposite the first pivot direction. The main shaft is driven by the pump handle to rotate approximately a first half of a predetermined rotational distance in a first rotational direction a first time the pump handle is pivoted out from the starting position in the first pivot direction, and rotate approximately a second half of the predetermined rotational distance in the first rotational direction a first time the pump handle is pivoted back to the starting position in the second pivot direction. The main shaft rotates in a second rotational direction opposite the first rotational direction a second time the pump handle is pivoted in the two-movement push-pull motion.
