  • Patent number: 4114553
    Abstract: A device for mooring marine units when attached to a wharf or which serves as a cleat when mounted on the deck of a boat. The device comprises a hollow yieldable plastic or preferably metallic tubular anchor element with open ends at opposite ends of a bore defined by the walls of the element, which when secured in upright position serves as a chimney for circulating air therethrough to maintain the rope anchor element relatively cool.Certain walls of the tube are provided with keyhole shape slots which are open at the ends of the tube for admitting a rope therethrough which is slid endwise of the slot to the enlarged circular terminal inner end. To prevent its withdrawal, the rope has a knot larger than the slot. In the plastic tube the edges of the slots can be spread so that the rope will pass tightly therethrough and the resilient nature of the plastic acts to yieldingly resist tugging as the boat rides up and down.
