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.

Claims

1. A ladder assembly for attachment to a wharf or pier comprising:

a pair of elongated frame members, each frame member having a channel extending the length of the frame member;

a ladder member mounted in said channels for movement along the length of said frame members, said ladder member including a pair of vertical side members interconnected by a plurality of rungs; and

a flat plate member attached to and extending from one of said rungs in a plane generally perpendicular to said side members, said ladder member being mounted in said channels for free movement along the length of said channels, and with said ladder member being of a material having sufficient weight and density so that said ladder member will fall into the water surrounding said wharf or pier until said plate member contacts said wharf or pier.

2. The ladder assembly of claim 1 further including a support having at least one post member for attachment to said wharf or pier and a bracket secured to and extending from the post member and being attached to the upper end of said frame members, said bracket acting as a stop to prevent upward movement of said plate member.

3. The ladder assembly of claim 1 further including a rope and pulley assembly wherein said rope is attached to said ladder member and said pulley is attachable to said wharf or pier in a position to receive said rope.

4. The ladder assembly of claim 3 further including a cleat member for attachment to said wharf or pier for the purpose of receiving said rope so as to secure said ladder member in a fixed position.

5. The ladder assembly of claim 1 wherein said ladder member has a top rung one end of said ladder and wherein said plate member is attached to said top rung.

6. A ladder assembly for attachment to a wharf or pier comprising:

a pair of elongated frame members, each frame member having a channel extending the length of the frame member;

a ladder member mounted in said channels for movement along the length of said frame members, said ladder member including a pair of vertical side members interconnected by a plurality of rungs;

a flat plate member attached to and extending from one of said rungs in a plane generally perpendicular to said side members; and

a support having at least one post member for attachment to said wharf or pier and a bracket secured to and extending from the post member and being attached to the upper end of said frame members, said bracket acting as a stop to prevent upward movement of said plate member.
