Abstract: One possible embodiment of the invention could comprise an interlocking device for the adjusting the length of at least one telescopic tow bar leg of a tow bar. The telescopic tow bar leg could comprise an inner bar and outer bar, the inner bar being generally movably received by the outer bar. Movement of an outer bar mounted pawl into engagement with inner bar may lock the inner bar in relationship to the outer bar. A pawl release mechanism may be used to either act directly upon the pawl or to rotate a cam that contacts the pawl. Either action generally causes the at least two surfaces of the pawl to move out of contact with the inner bar's pawl engagement area, thus substantially allowing the inner bar to move relative to the outer bar. This could allow a user to adjust the length of the telescopic leg.

Abstract: A towbar for a vehicle. The towbar includes a yoke and a drawbar rotatably connected to the yoke. The drawbar is attached to the towing vehicle. A pair of connecting bars is attached to the yoke and to the vehicle being towed. A lock assembly is connected between the yoke and the to drawbar. The lock assembly is adapted to move from a first position in which the drawbar is free a to rotate and a second position in which the drawbar is retained to the yoke.

Abstract: The specification discloses several embodiments of an interlocking device. The specification discloses a preferred embodiment of an interlocking device having an inner bar slideable within the confines of an outer bar. The outer bar has a first end and a second end. When the inner bar slides towards the second end of the outer bar, a plug, which is attached to the inner bar, is adapted to abut a plug barrier thereby preventing the inner bar from sliding towards the second end.The outer bar of the interlocking device further defines an interlocking member passage and an interlocking member stop. The interlocking device further has an interlocking member attached to the inner bar. When the inner bar slides towards the first end of the outer bar, at least a portion of the interlocking member moves transverse to the sliding axis of the inner bar and into the interlocking member passage. The interlocking locking member further abuts the interlocking member stop, thereby stopping the inner bar from sliding towards the first end of the outer bar. The interlocking device preferably has a cam attached to the outer bar and adjacent to the interlocking member stop. The cam may be actuated to release the interlocking member from the interlocking member stop thereby allowing the inner bar to slide through the confines of the outer bar.
