ABSTRACT:
A hitch apparatus having a modular configuration for mounting to a vehicle, in order to conveniently hitch a trailer thereto. The modular hitch apparatus has movable structure that is configured for selectively tilting a trailer with respect to the vehicle so as to facilitate loading and unloading equipment, automobiles, materials, etc., onto or off of the trailer. The hitch apparatus includes an elongated chamber-like structure that has an open top and an interior which is in communication with the open top. The chamber-like structure may be configured to be anchored to the frames of a variety of vehicles including conventional pickup trucks, cars, etc. The chamber-like structure is sized and configured in the manner of a conventional pickup truck bumper. The apparatus further includes an engageable member such as a ball hitch movably connected to a structural trailer part (e.g. a trailer hitch socket). This ball hitch is mounted for movement with respect to the chamber-like structure, so that the combination hitch connection may be selectively positioned through the use of extendable members. Thus, the ball hitch may be moved between two major positions; one being a lowered position adjacent the chamber-like structure and the other being a raised position above the chamber-like structure. The extendable members move an engageable member in such a way as to facilitate aligning the engageable member with the hitchable structure of a trailer, so that the engageable member and trailer may be more easily connected.
