Abstract
A hitch coupler includes a frame having vertically spaced apart plates extending outwardly therefrom. Each plate includes a pin receiving aperture adapted to receive a pin member therethrough. The pin member is moveable between extended and retracted positions. The pin member includes a pin housing having a vertical guide slot disposed thereon. A lock mechanism is pivotally coupled to the frame member and includes a locking flange which is adapted to engage the guide slot when the pin member is in the extended position. The lock mechanism is biased towards a lock position such that the locking flange of the lock mechanism is adapted to automatically engage the guide slot disposed on the pin housing of the pin member when the guide slot is aligned with the locking flange of the lock mechanism. In the locked position, the locking mechanism acts to retain the pin member in the extended position.
