ABSTRACT:
A hitching device is provided for connecting a trailer to a towing vehicle. The device reduces shocks and vibrations that can be transmitted between the trailer and the towing vehicle. The hitching device mounts on the rear section of the towing vehicle. A swing plate has hitching means attached to it for connection with the trailer. The swing plate is connected to swing means which allow the plate to swing forward or rearward. As the swing plate moves forward and rearward the hitching means remain at a constant angular orientation. The swing plate has a central position wherein the swing plate is at a lowest level. As the swing plate swings forward or rearward out of the central position it moves to a higher level. Gravity tends to force the swing plate back to the central position when the swing plate is displaced from the central position. The swing of the swing plate reduces shocks that typically are transmitted between the trailer and the towing vehicle. The tendency of the swing plate to be moved to the central position damps vibrations that can be transmitted between the trailer and the towing vehicle.
