Abstract
A screw jack assembly includes a first body defining a longitudinal axis and a screw drive disposed within the first body. The screw jack assembly also includes a second body movable relative to the first body and coupled to the screw drive, and a first gear coupled to the screw drive. The screw jack assembly further includes a handle assembly having a tube member coupled to the first body. The handle assembly also includes a second gear coupled to the first gear. The handle assembly further includes a handle member coupled to the second gear and adapted to rotate about a rotational axis substantially perpendicular to the longitudinal axis. The handle member is adapted to selectively rotate between an operating position and a stowed position about the longitudinal axis based, at least in part, on rotation of the tube member relative to the first body along the longitudinal axis.
