Abstract
A trailer coupling has a removable unitary coupler-receiving element that includes both a ball configured to receive a spherical cavity coupler and a cylindrical neck configured to receive a drawbar eye. A latch is movable about a vertical axis between a closed position, where it engages the coupler-receiving element, and prevents removal of the eye from the neck, and an open position where it is separated from the coupler-receiving element and permits use of the ball. A locking mechanism locks the latch in its closed position and holds it against free movement from its open position. A trigger located in a finger-receiving cavity in the latch releases the locking mechanism. Because the latch rotates about a vertical axis, it can have a low profile and not extend substantially above the ball in the orientation.
