ABSTRACT:
An adaptor plate generally Y-shaped in plan is provided having a central opening formed therethrough. The adaptor plate is positionable over the step plate of a step bumper with the opening in the plate registered with the central hitch ball mounting shank receiving opening formed in the step plate and the adaptor plate is secured to the step plate through the utilization of the threaded shank of a hitch ball and the attendant nut and washer therefor. The free ends of the divergent arms of the Y-shaped adaptor plate project rearwardly of the rear margin of the step plate and have front-to-rear extending openings formed therein with which elongated hooks of trailer safety chains may be engaged and the forwardly projecting stem of the Y-shaped adaptor plate at least closely opposes the center face plate portion of the associate step bumper projecting upwardly from the forwardly margin of the step plate to thereby limit angular displacement of the adaptor plate relative to the step plate about the shank of the attaching hitch ball. The adaptor plate defines a rearwardly opening recess between the free ends of the rearwardly divergent arms of the adaptor plate and the recess provides clearance for a trailer hitch tongue coupler engaged with the hitch ball.
