Abstract

Abstract Disclosed is a telescoping trailer hitching post having a ball coupling member at its upper end for coupling engagement with a coupling socket at the front end of a trailer tongue, a pair of rings welded to opposite sides of the post, a chain anchored at its one end to one of the rings and adapted to be wrapped around the trailer tongue and locked by means of a padlock to the one or to the opposite ring to prevent theft of the trailer. A ground receptacle is anchored in concrete with its upper end flush with the surface of the ground, and the post is telescoped within the receptacle between a completely housed position within the receptacle and a raised position above the ground. A pair of vertically spaced discs are provided near the bottom end of the post, for cooperative engagement with a vertical key welded to the inside of the receptacle adjacent its top edge to support the post in the raised position and to prevent the post from being pulled out of the receptacle.
