Abstract

A compactable, foldable, floatable, continuous, boom-fence is quickly and readily launched, often from the deck of a boat, via accordian-like folded sections, in turn quickly interconnected to like sections, to form an overall boom-fence projecting above the water surface, while also depending below the water surface, thereby creating a water boom to fence a large water surface area during the control of a contaminate unwantedly spreading over a surface of water. Each section of the boom-fence comprises planar rectangular fence panels flexibly secured together with flexible coupling panels and cable, and provided with both planar buoyant materials and planar retractable hinged dampening fins, tending to keep the planar rectangular fence panels upright during their deployment, when confronted with forces created by waves, wind, and tides or currents. In a preferred embodiment the planar rectangular fence panels are made of sheet metal having their tops folded over a continuous cable, having their bottoms equipped with foldable, hinged, oppositely positioned sheet metal dampening fins held in their active dampening positions by stiffleg springs, having planar rectangular foam floats attached to each side of the fence panels nearer their top than their bottom, and having each end of each fence panel secured to a flexible coupling made of coated fiberglass cloth and between sections composed of several panels, Velcro fasteners join the midsection of such a flexible coupling, where also cable connectors are utilized.

Dependent claims

A compactable, foldable, floatable, continuous boom-fence quickly deployable to control the spreading of contaminates over water surfaces, comprising multiple planar fence panels;

each multiple planar fence panel having a top portion formed about and attached to a continuous cable extending throughout all fence panels and between all adjacent planar fence panels, each multiple planar fence panel having a slotted bottom portion with the slots staggered horizontally to accept projections of dampening fins located on each side, each multiple planar fence panel having dampening fins with their projections inserted through the slots of the bottom portion and then their outer portions of the inserted projections are twisted to a right angle thus creating a limited hinging action, whereby the dampening fins are either folded parallel to the planar fence panel for compactness or are deployed to their approximate right angle position, and each dampening fin is notched to allow clearance for the twisted outer portions of the inserted projections of the opposite dampening fin, each multiple planar fence panel having positioners consisting of stiffleg springs, which deploy and lock into position upon the full opening of the dampening fins, keeping the dampening fins hinged at right angles on both sides of each planar fence panel, and the opening of the dampening fins is accomplished by action in the water or by gravity and thereafter the stiffleg springs maintain the fins in an open position on both sides of each planar fence panel, each multiple planar fence panel having an upper middle portion having in turn planar floats consisting of a foamed material of a density of approximately four pounds per cubic foot and of a sufficient volume to provide adequate buoyancy to support the wetted weight of the entire planar fence panel and to provide freeboard of approximately 1/3 of the height of the panel to extend above the mean water line by 1/4 of the volume of the float and be equally distributed from end to end, such additional buoyancy complements the functioning of the dampening fins;
and each multiple planar fence panel having flexible couplings extending to adjacent planar fence panels consisting of woven fiberglass cloth impregnated with fortified silicone rubber.

A compactable, foldable, floatable, continuous boom-fence quickly deployable to control the spreading of contaminates over water surfaces, comprising:

(a) multiple boom-fence panels, each having:
(1) a planar metallic rectangular body for upright positioning relative to the surface of the water with portions located both above and below the water surface,
(2) planar floats secured to each side of the planar metallic rectangular body to maintain its upright positioning with portions located both above and below the water surface;
(3) planar metallic dampening fins foldably secured to the planar metallic rectangular body to be during deployment below the surface of the water to maintain the upright position;
(4) a continuous surrounding integral metallic receiver at the top of the planar rectangular body to receive a continuous joining member extending beyond to other boom-fence panels.
(b) continuous multiple boom-fence flexible couplings, each used between boom-fence panels to accommodate relative changing positions thereof, while continuing the continuity of an entire boom-fence, having:
(1) a coated fiberglass cloth impregnated with fortified silicone rubber extending between and beyond adjacent boom-fence panels;
and
(2) fasteners to secure the fiberglass cloth to adjacent boom-fence panels;
and
(c) centrally detachable boom-fence flexible couplings, each used between boom-fence panels, which are to be conveniently connected and separated during use, to accommodate such connections and separations and to continue to accommodate, when connected, relative changing positions of the boom-fence panels, while continuing the continuity of the entire boom-fence, having:
(1) coated fiberglass cloth impregnated with fortified silicone rubber in two portions to be releasibly joined together at their overall midsection and, when joined, extending between and beyond adjacent boom-fence panels;
(2) fasteners to secure the respective two portions of this coated fiberglass cloth to adjacent boom-fence panels;
and
(3) a joining member section with fasteners, at respective ends, to join together at their midsection the coated fiberglass cloth impregnated with fortified silicone rubber extending from adjacent boom-fence panels.
