Abstract
Floats having a buoyant portion and a chamber portion hold liquid within their chambers above the interface of the surrounding body of liquid and gas which creates a downward force which stabilizes the float. If the liquid is water, the float holds water in the inner chamber which is disposed above the waterline of the body of water in which the float is suspended. The elevated water exerts a downward force that acts against rocking, swaying, and other destabilizing forces.
Claims5
A float suitable for supporting objects on water comprising:
- at least one floatation device comprising a buoyant material of a size sufficient to support at least 10 pounds above a waterline, wherein said floatation device is unitary with or secured to an inner chamber wherein the inner chamber comprises a chamber top and a inner wall secured or unitary with the chamber top, wherein the inner chamber is open only on a side opposite to the chamber top, and wherein the inner chamber is adapted to be substantially filled with a volume of the water thereby creating suction which is sufficient to raise the water in the inner chamber above a waterline, and wherein the water raised above the waterline remains in connection with the water of the waterline,
- wherein the suction stabilized float has only one inner chamber, and
- wherein the float additionally comprises an umbrella wherein the umbrella is attached to the chamber top via a tube that penetrates the chamber top but maintains a gas and liquid tight seal with the chamber top.
