Abstract
A hitch coupler includes a frame that includes a back plate, a first plate connected to the back plate, a second plate connected to the back plate at a position spaced from the first plate extending between the first plate and the second plate and cooperating therewith to define an interior space, and a third plate connected to the back plate spaced from the second plate, wherein the first, second and third plates each include an aperture extending therethrough. The frame also includes a pin extending through the first, second and third apertures, such that the pin extends through the interior space and is adapted to slide within the apertures between an extended position and a retracted position, and a spring member biasing the pin towards the extended position.
