<p>Jacks and handle systems for jacks are disclosed. In one embodiment, a jack includes a base, a pivotable handle sleeve, a lifting portion, coupling structure affixed to at least one of the base and the lifting portion, and a first elongate rigid member. The coupling structure defines a passageway extending generally perpendicular to the base and an opening generally perpendicular to the passageway. The first elongate rigid member has proximal and distal ends, and the distal end of the first elongate rigid member is configured to interact with the pivotable handle sleeve to actuate the lifting portion. The distal end is also configured to pass through the passageway and interact with the opening to operatively couple the first elongate rigid member to the lifting portion apart from the pivotable handle sleeve such that the first elongate rigid member extends generally perpendicularly to the base.</p> |
