发明名称 Weather resistant dock walkway
摘要 A weather resistant dock walkway comprises a dock walkway substructure in combination with a plurality of elongated planks each with a first and second opposite ends. The planks are rotatable between a horizontal position and a vertical position, and are arranged side-by-side. The first and second opposite ends of each plank are attached to the opposite ends of the substructure. The planks are responsive to contact with a body of water such that the planks rotate from a horizontal position to a vertical position to enable surging water to circulate freely between the vertical planks to prevent surge damage to the weather resistant dock walkway. A ratchet system can be used to reversibly lock the planks in a vertical position.
