A powered maneuverable and retractable trailer jack adapted for attachment
to a tongue of a trailer has an external sleeve, a gear rack on an
exterior of the external sleeve, a housing containing at least one gear
engaged with the gear rack and operative to move the external sleeve
relative to the housing, the housing including a mount configured for
attachment to the tongue of a trailer whereby the external sleeve is
laterally offset relative to the tongue of a trailer, an internal rod
within the external sleeve, the internal rod extending through a wheel
fork at a lower distal end of the internal rod and the external sleeve
and attached to a drive gear which is engaged with a shaft gear upon a
drive shaft rotationally mounted in the wheel fork, and a drive sprocket
attached to the drive shaft, a wheel mounted upon an axle rotationally
mounted within the wheel fork, and a wheel sprocket attached to the axle
proximate to the wheel, and a chain which extends continuously from the
wheel sprocket to the drive sprocket; the lateral offset of the trailer
jack relative to the trailer tongue being equal to or greater than a
width of the wheel fork.
