ABSTRACT:
An adjustable fifth wheel hitch includes a support frame having base rails that are secured to the frame of a vehicle and a pair of spaced guide rails that bridge between the base rails. The fifth wheel hitch also includes a head assembly having a jaw assembly for engaging a kingpin on a trailer. A head support and a pair of uprights mount the head assembly for relative fore-and-aft sliding movement along the guide rails between a towing position and a maneuvering position. A releasable lock secures the head assembly in either selected position. The lock includes a dual bar latch and a leaf spring for biasing the latch into a locking position. The dual bars of the latch are offset or dimensioned so that each bar is selectively received in only one of two similarly offset or dimensioned, cooperating apertures formed in one of the guide rails.
