Abstract:
A ladder includes a first section having at least one step. The ladder includes a second section having a least one step. The ladder includes a platform attached to the first and second sections. The ladder includes a hinge mechanism connected to the first section and second section, about which the first section and second section move between an open state, where the first and second sections are in an angular relationship for use, and a folded state where the first and second sections and the platform are essentially in parallel, as shown in FIGS. 4 and 5.The ladder includes a foldable tray mechanism attached to the hinge mechanism about which the foldable tray mechanism moves between the open state independently of the first and second sections, where the foldable tray is in an angular relationship with the first and second sections for use, and a folded state where the foldable tray essentially forms a plane with the first section. A hinge for a stepladder. A step to a ladder. Methods for using a stepladder.
