ROPE LADDER WITH MOLDED HARD ELASTOMER STEPS AND A METHOD FOR ASSEMBLY OF THE SAME Abstract of the Disclosure A rope ladder. Each step is a molded one-piece hard elastomer member having a pair of rope-receiving openings, the upper outlet from which closely confines a pair of ropes, while the bottom of the opening is much wider. Each opening tapers inwardly from bottom to top, and each step has a pair of vertical bolt openings therethrough adjacent each opening. A separate wedge collar for each opening bears against the bottom of each step and has a single through opening; at its upper end the opening is the same width as the lower end of the step's opening, and it tapers inwardly down to an outlet that closely confines the two ropes. Each wedge collar has a pair of vertical bolt passages aligned with those of the step to enable bolting the step to the collar. A generally diamond-shaped wedge heart is wedged in between the two ropes of each pair, lying partly inside the opening through the step and partly inside the opening through the wedge collar. The wedge heart has an upper vertex, a lower vertex, and two rope-engaging side grooves, which lock the pair of ropes in place.
