Filed:

Jan 27, 1986

Appl. No.:

6/822650

Inventors:

James R. Dykes - Savannah GA

International Classification:

F16B 4100

US Classification:

70232

Abstract:

A trailer king pin lock for preventing theft of a trailer by negating connection of a trailer king pin with a tractor fifth wheel coupling. A sleeve is provided that is receivable about the trailer king pin. A locking unit housing, which extends radially relative to the sleeve, is attached to the sleeve and carries a locking cylinder for sliding movement therein. A bore is provided in the sleeve and is enclosed by the housing. The locking cylinder passes through the bore for insertion into an annular groove typically found in a trailer king pin. A radially extending locking cylinder retaining pin is carried by the locking cylinder and is outwardly extendable upon the turning of a key inserted into the locking cylinder. The outward extension of the locking cylinder retaining pin prevents extraction of the locking cylinder from the annular groove through the bore, thereby fixing the locking cylinder within the annular groove and retaining the king pin lock on the king pin against unauthorized attempts at removal therefrom.
