ABSTRACT:
A ladder assembly for ease of access to a wharf or pier is disclosed. The ladder assembly includes a pair of vertical frame members having channels therein which are disposed about a ladder which is free to move upwardly and downwardly within the channels. The ladder may be secured to a cleat on the pier in a raised position when not in use. Upon releasing the ladder from the cleat, the ladder will move downwardly under its own weight so that its lower portion enters the water. A plate member attached to the top rung of the ladder will engage the deck surface of the pier in the lowermost position of the ladder.
