ABSTRACT:
A latch for a hitch having release mechanism including a pair of parallel oriented cylinders which are disposed to lock together two separable elements of a hitch. The locking cylinders are disposed between the confronting surfaces within portions of the separable hitch elements to receive a compression force across the both of the cylinders when the hitch elements are receiving an tensions so as to separate them. To release the hitch elements while under tension, one of the cylinders is rotated, causing the adjacent, parallel disposed cylinder to rotate in the opposite direction, rolling over the confronting surfaces in the same directions, and eventually out of and releasing the two separable hitch elements. Multiple embodiments are shown which relate to variations in hitch styles, and further embodiments relate to smaller clamping devices, such as hand tools, and to rotational couplers which are releasable while under torque.
