摘要： A travel trailer stabilizing system having a right and left compound above-axle strut for bracing a trailer body at the axle or axles, each compound strut having an overlever arm for applying a stiffening force with a mechanical advantage to oppose any oscillatory motion of the frame on the tires. The mechanical advantage of the lever is configured to transfer a part of the weight of the trailer from the tires to the rigid struts.

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.

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 hydraulically extensible frame is coupled to the hitch portion of a trailer by a pivoting mount. The pivoting mount permits the frame to pivot between a generally vertical operative position and a generally horizontal stowed position. A foot member is secured to an end of the frame opposite the pivoting mount. The foot member engages the ground. An actuator is carried by the frame in a location adapted to be engaged by a foot of a human user when the frame is in the operative or deployed position. The actuator pivots relative to the frame for storage and use as a handle. The actuator selectively extends the frame to raise the hitch portion in response to actuation by the foot of the user.

摘要： The present invention relates to a trailer safety stand for temporarily supporting a conventional trailer having a landing gear, wherein the stand comprises a pedestal having a top for engaging the underside of the nose portion of a trailer and a bottom for engaging the ground; means for adjusting the height of the pedestal; a locking device for fixing the height of the pedestal; and means for actuating and de-actuating the locking device. In one embodiment of the present invention, the means for actuating and de-actuating the locking device is a lever that is pivotally connected to the pedestal at a first point along the lever and connected to the locking device at a second point along the lever. When a force is applied away from the pedestal at a third point along the lever, the locking device is actuated and the height of the pedestal is fixed. When a force is applied toward the pedestal at the third point along the lever, the locking device is de-actuated and the height of the pedestal is adjustable.

摘要： A powered, directionally steerable trailer jack that can be used to elevate and lower a trailer tongue and having a caster wheel assembly affixed to a lower end of the jack. The caster wheel assembly includes a shroud having the wheels' axle journaled for rotation at a lower end thereof along with a pair of shafts also journaled for rotation in the shroud and oriented parallel to the axle. A chain and sprocket arrangement provides a low-speed, high torque transmission between one of the shafts and the axle and a high-speed, low torque transmission between the other of the shafts and the axle. The trailer jack assembly can be tilted out of its vertical disposition to provide adequate clearance when the trailer is being pulled over uneven road surfaces. The power for driving the wheels may be provided manually by means of a crank for turning one or the other of the shafts or by an electric motor coupled one of the shafts.
