ABSTRACT:
A tow hitch assembly for connecting a tractor vehicle to a trailer vehicle includes a mounting member adapted to be secured to the frame of one of the vehicles and a tow bar releasably securable to the mounting member at one end and adapted to be secured at its opposite end to the other vehicle. The connection between the tow bar and mounting member is defined by a pair of spaced-apart, parallel disc-shaped knuckles mounted on either side of a tangential flat surface on the mounting member and by a rounded nose forming the end of the tow bar which nose has a pair of flat sidewalls. The nose is sized for close-fitting insertion between the knuckles and has a radius of curvature that is the same as the radius of curvature of the knuckles. The knuckles and the nose have alignable bores so that a pin may be inserted therethrough to releasably secure the tow bar and mounting member together. By having a common radius of curvature with the knuckles, the tow bar is pivotal about the pin in a vertical plane with the rounded surface of its nose adjacent the tangential flat surface and with its sidewalls adjacent a respective knuckle. In an alternate embodiment, the mounting member is releasably secured to a bracket mounted to the frame of one of the vehicles.
