Abstract
A hitch coupler () including an E-shaped frame (), a pin () and a conical spring (). The frame () includes a back plate (), a top plate (), a middle plate () and a bottom plate (). The top (), middle () and the bottom () plates include aligned openings. The pin () extends through the aligned holes () in the top (), middle () and bottom () plates, with the pin () being configured to slide within the aligned openings (). The conical spring () surrounds and engages the pin (). The conical spring () biases a bottom of the pin () through the middle plate () and the bottom plate (). The pin () includes a retainer () that extends through a slot () in the top plate () as the pin () is pulled against the bias of the spring (). The retainer () abuts against a top of the top plate () when the retainer () is located above the top plate (). The retainer () is located between the pin () and the spring ().
