Abstract
The invention provides an apparatus for alignment of a trailer hitch with a trailer tongue, so that the operator does not leave the cab of the towing vehicle in order to facilitate the alignment. The system may comprise a control assembly and a remote assembly, the control assembly further comprising a display unit and a receiver, and the remote assembly further comprising a video camera, a transmitter, and a light. The remote system may be removably attached to the rear end of the towing vehicle and positioned to provide a vertical view of the hitch area, and the control assembly may be removably attached to a surface within the cab. The transmitter provides a wireless video signal of the hitch area for reception by the receiver and subsequent display on the display unit. Power for the system may be provided by batteries, and in the case of the remote assembly, a plug adaptable for attachment to the standard cable socket for trailer braking and lights. The system allows the operator to see the hitch area from the operator'"'"'s seat during the attachment process so that the operator may properly align the towing vehicle with the tow object without requiring a second person or the operator having to get out and check the alignment. The system thus promotes safety and reduces the probability of damage to the towing vehicle by the tongue of the trailer. An illumination means such as a light may be provided with the remote assembly for use during nighttime and inclement weather.
