An Articulated Ladder is a portable ladder with one or more pairs of locking hinges which allow the ladder to be set up in several configurations such as a single or extension ladder, with or without a stand-off, a stepladder, a trestle ladder, scaffold or work table. Each pair of articulated joints in the ladder can be locked in one or more positions to accommodate the various configurations. The locking positions of the hinges allow set-up at the proper angles to accommodate each configuration that the manufacturer has designated.
