A sliding hitch with a self-arming latch is described. The hitch includes a carriage slideably mounted on a base. The base includes a latching pin on a pivot arm that is biased to extend toward engagement with the carriage and a rotatable shaft with an arming member and a locking member. Rotation of the shaft to an unlocked orientation, cams the pivot plate away from the carriage to withdraw the pin and enable sliding of the carriage on the base. An arm of the arming member is also rotated into the path of a protuberance associated with the carriage. Contact between the protuberance and the arm during sliding of the carriage along the base causes rotation of the shaft to a locked orientation enabling extension of the pin toward engagement with the carriage and engaging the locking member with the pivot plate to restrict withdrawal of the pin. |
