摘要： A trailer adapted to be coupled to a tow vehicle and including a frame including a draw bar tube defining a longitudinal axis. The trailer includes a drawbar support pivotally coupled to the draw bar tube and rotatable relative to the drawbar tube about an axis parallel to the longitudinal axis. The drawbar support is biased toward a substantially horizontal orientation. A sliding member is receivable in the drawbar tube and is configured for movement along the longitudinal axis in response to movement of the tow vehicle. A latch member is connected to the sliding member. The latch member is configured to move in response to movement of the sliding member from a first position wherein the drawbar support is retained in a substantially vertical orientation to a second position wherein the draw bar support is free to rotate toward the substantially horizontal orientation.

摘要： A receiver extends from the top of a retractable wheel assembly to receive the lower end of a jackstand or the like. Upon exerting pressure on a foot operated plate, a wheel is extended from the bottom of a plate and locked in place with a catch to permit transport of a trailer or the like attached to the jackstand. Upon release of the catch, the wheel will retract to bring the plate into contact with the ground and immobilize the trailer.

摘要： An improved jack assembly for use with a trailer tongue of a towed vehicle. The jack assembly including telescoping height adjustment of the assembly, a pivot assembly for pivoting between a vertical and horizontal stowed position, and a clip for maintaining a handle assembly in a stowed position when not in use. The jack assembly also includes the use of bushings for the telescoping tubes to enhance the sliding movement between the tubes and aid in maintaining the axial alignment of the tubes thereby extending the life of the jack assembly. The pivot assembly further includes an attachment bracket that may be rotated to accommodate at least two different sizes of trailer tongues.

摘要： A jack with an optionally pivoting foot provides a trailer owner the ability to change between a wheel and a flat foot or a flat foot and a wheel upon a jack depending from a trailer tongue. The present invention has an optional foot attached to a jack that rotates from a horizontal position to underneath an existing foot. The foot has two parallel spaced apart flanges extending upwards from a base. The flanges have a bolt through a centered hole near the wheel about which the pivoting foot rotates. Opposite the base, the flanges have three holes about the perimeter through which a handle inserts. The handle secures the foot in either horizontal or vertical configurations. When in a vertical configuration, a wheeled jack does not move upon nor embed into the ground. A jack with a flat foot prevents a trailer from moving.

摘要： A trailer mover secured to the forwardly extending tongue of a recreational or multi-purpose trailer. The trailer mover includes a bracket pivotally attached to the trailer tongue and a gearbox rotatably attached to the bracket. The gearbox is pivotally movable between a lowered vertical working position and a raised horizontal storage position. Further, the gearbox is selectively rotatable with respect to the bracket to allow steering when in the working position. A rubber-tired groundwheel extends from the distal end of the gearbox and is powered by a hand crank, which drives a set of gears which provide a mechanical advantage.

摘要： The swivel jack assembly is used with trailers to vertically position a trailer tongue for mounting onto a hitch of the towing vehicle. The swivel jack assembly includes a jack-mounting bracket welded to an outer housing of the jack, and a tongue-mounting bracket mounted onto the tongue portion of a trailer. The jack also includes a novel swivel mechanism for pivoting the mechanism in either an upright support position or a horizontal stowed position. A cup-shaped section of the jack-mounting bracket nests within a cup-shaped section of the tongue-mounting bracket. When in the upright position, the jack extends vertically and may be used to raise or lower the tongue and support the trailer. The swivel jack assembly keeps the trailer in a level position when the trailer is disengaged from the towing vehicle. The swivel jack assembly is pivotally mounted onto the trailer tongue such that they can be pivotally repositioned to a stowed position when not in use.
