Abstract: An improved hinge for a collapsible ladder includes a pivot pin which has a sufficiently simple construction to permit it to be fabricated by die-casting on a cost-competitive basis. The simple construction is made possible by an improved axial detent arrangement for a shaft which rotates and slides within the hub and to which the hinge locking pins are secured. The detent arrangement includes a detent bore extending radially biased against the shaft. A suitable detent recess in the shaft is angularly aligned with the detent bore for each locking position of the shaft. Axial alignment of the bore and a recess is achieved by fully extending the shaft out of the hub against the restoring force of a bias spring in the hub. The recess and bias member are contoured to permit disengagement of the detent by rotation of the shaft but not by axially applied forces.
