摘要： A safety hitch for a trailer or the like which replaces the conventional safety chains of a trailer hitch. A conventional tongue member is adapted to be connected to a trailing vehicle and has a conventional connecting structure on one end thereof such as a hole for reception of a pin or other conventional structure such as that used for ordinary ball-type hitches. An abutment member is spaced upwardly from but is attached to the tongue member. A rigid safety member is pivotally attached to the tongue member through a lever mechanism and horizontally disposed pivotal points. The safety member extends under the abutment member and between the abutment member and the tongue member. The other end of the of the safety member is attached through a vertical pivot, which is located directly above the vertical pivot of the tongue member. Additionally, a horizontal pivot is disposed on the other end of the safety member adjacent the vertical pivot. The safety member and its associated structure does not interfere with the ordinary function of an ordinary trailer hitch apparatus, and it furthermore allows the pulling vehicle to maintain control of the trailing vehicle even if the primary and conventional hitch mechanism becomes unfastened. This structure prevents the tongue member from digging into the ground as is often the case when conventional safety chains are used.
