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.
