ABSTRACT:
A quick hitch coupling apparatus for coupling a trailer provided with a hitch coupler and a vehicle provided with a tow bar receiver channel, includes a hitch sleeve and a tow bar. The hitch sleeve is fit slidably over the receiver channel of the vehicle and is releasably secured thereto. The tow bar is releasably and pivotally connected to the hitch sleeve at one end, and is provided with a hitch ball at its opposite end. The hitch ball is moved laterally from side to side to the position the ball beneath the hitch coupler of the trailer. It may be necessary to move the tow vehicle forward or rearward a short distance to position the tow bar ball directly beneath the trailer coupling. The trailer is then connected to the hitch ball, and the vehicle is moved forward to straighten the connections between the vehicle, the tow bar, and the trailer. The user then releases the connections between the hitch sleeve and receiver channel, and the hitch sleeve and the tow bar, and continues to back the vehicle toward the trailer to insert the tow bar into the receiver channel. The user then releasably secures the hitch sleeve to the receiver channel, and the receiver channel to the tow bar, to establish a connection between the trailer and vehicle that is equivalent to the connection provided by conventional receiver channel type trailer hitch assemblies.
