A hitch for allowing a trailer to be first disconnected from a vehicle, to be then jacked so it is level with the support surface, and then be automatically jacked back to the level of the vehicle so that it can be easily reconnected to the vehicle. A switch is pivotally associated with the trailer for movement in a plane parallel to a vertical plane extending along the longitudinal axis of the trailer. A lock is provided for locking the switch in any one of an infinite number of positions with the longitudinal axis of the switch in the plane parallel to the vertical plane extending along the longitudinal axis of the trailer.
A combination, retractable jack and support apparatus for trailer tongues. The jack is pivotally connected to counterbalance which is used to raise or lower the support apparatus. The design provides a sturdy horizontal support for trailers in port, disconnected from towing vehicles; and a means to facilitate mechanical retraction of the support apparatus when coupling to a towing vehicle for road travel.
An adjustable coupler apparatus for a trailer hitch includes a drawbar assembly and a hitch head assembly. The drawbar assembly is interconnected to a tow vehicle and includes an elongate bar and a drawbar angle adjuster that is pivotally interconnected and angularly adjustable relative to the bar. The hitch head assembly includes a ball component and a channel that is pivotally interconnected to the ball component. A horn is slidably received by the channel. The horn and the drawbar angle adjuster are selectively coupled to interconnect the trailer to the tow vehicle.
A spring bar for a weight distributing hitch includes an elongated body carrying an integral hanger for securing to a trailer to be towed behind a towing vehicle. Preferably, the integral hanger is a lug with a cooperating retaining tab. The spring bar also includes a trunnion allowing cantilever mounting of the spring bar to a ball mount head of a trailer hitch that is secured to a towing vehicle.
A towing device is provided including a bracket (12) and an elongate hitch rod (14). The bracket (12) includes a longitudinal bore (34) and one or more pins (36) oriented transverse to the longitudinal bore (34). An end portion of each pin extends partially into the longitudinal bore. The hitch rod (14) includes a cylindrical shaft (50) and a clevis (52) connected to the shaft's distal end. The clevis (52) is attached to the shaft (50) in a manner that weights the shaft in a desired orientation. The shaft (50) includes at least one groove (60) with a spiral portion (62) and a notch (64). The spiral portion (62) extends from the shaft's proximal end and ends with the notch (64). During use, the transverse pin (36) engages the notch (64), thereby locking the rod (14) with the bracket (12). The weighted orientation of the shaft encourages this engaged arrangement.
The recreational vehicle jack remote control is for use with a recreational vehicle having a pair of support jacks which are raised and lowered by an electric motor connected to the jacks. The electric motor is controlled by a normally open, double-pole, triple throw switch in the recreational vehicle. The recreational vehicle jack remote control is a modification of the circuit which includes a portable radio frequency transmitter, at least one radio frequency receiver mounted in the recreational vehicle, and a plurality of relays. The transmitter has an "up" button for raising the support legs, and a "down" button for lowering the support legs. When the "up" button is pressed, the relay coil of at least one relay is energized, closing the relay switch contacts to apply current to the electric motor with the proper polarity for raising the legs. When the "down" button is pressed, the relay coil of at least one relay is energized, closing the relay switch contacts to apply current to the electric motor with the opposite polarity for lowering the legs.
