ABSTRACT:
A grappling hanging device for attachment to an overhead beam has a primary hanging hook mounted in a frame plate. A rectangular bar extends laterally from the base of the primary hanging hook. The width of the plate is slightly less than a circular area of the keyhole aperture and its thickness slightly less than the spaced walls of the keyhole aperture of the support plate. The opposite end of the support plate has a latching loop extending therefrom. When the lifting force is lowered, the support plate will rotate about the bar in the circular part of the keyhole opening, thereby swinging the opposed latch around to loop over the end of the hook. Once about 180.degree. rotation has occurred, the cross plate will slide to the closed end of the keyhole slot, and lock the hanging mechanism in place.
