Abstract
Abstract Two elements are hinged together by one end thereof and are detachably locked by the other ends to form the key holder. The detachable locking means includes in one embodiment, a cylindrical member having a slot therein and being screw threaded on the outer surface. The engaging ends of the element are kinked or misaligned and will enter the slots. A closure nut is screw threadably engageable on the screw threaded outer surface of the cylindrical member thus closing the slot. The outer side of the nut is apertured to permit free rotation of the nut on the element but preventing axial disengagement of the element from the nut when engaged on the cylindrical member. Another embodiment is provided with detachable locks at each adjacent pair of ends of the holder with the slots on one side being a relatively loose fit to permit the other ends to be displaced sideways from one another when the lock of the one ends are disconnected so that keys can be removed or replaced upon the holder.
