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.

Dependent claims

A pump handle system comprising:

a pump handle comprising a base portion and a handle portion, the pump handle operable to radially pivot at a pivot point in the base portion 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;
and
a main shaft driven by the pump handle, the main shaft configured 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,
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,
rotate approximately the first half of the predetermined rotational distance in a second rotational direction opposite the first rotational direction a second time the pump handle is pivoted out from the starting position in the first pivot direction, and
rotate approximately the second half of the predetermined rotational distance in the second rotational direction a second time the pump handle is pivoted back to the starting position in the second pivot direction.
