Abstract
A hinge and a reconfigurable ladder having at least one pair of hinges is disclosed. The ladder has stile sections connected together by the hinges. The hinges consist of two hinge members mountable to ends of respective stile sections. A hinge cover extends over and receives the hinge members which are pivotally connected to the cover. The hinge members are linked to each other to control the pivotal movement of the hinge member so that they both pivot in unison and to the same extend relative to the cover. The hinge members have locating apertures. A locking mechanism is cooperable with the locating apertures for locking the hinge members in a desired relative position to one another.
