This invention relates to a barrier to prevent flood water intrusion into a structure. More specifically, the present invention provides a portable barrier gate to seal openings in a structure to prevent flood water intrusion.
Homes and buildings located in flood-prone areas may be subject to occasional inundation with water during flood periods. The National Oceanic and Atmospheric Administration estimates that flood damage has resulted in around $8.2 billion from 2013 through 2023. Even small flooding in a residential structure, such as a single inch of flood water in a 2,500 square foot home, can result in about $25,000 in damage, according to the Federal Emergency Management Agency.
In order to minimize the damage and inconvenience from such occasions, devices have been suggested for removable installation in structure openings located at or below expected flood levels. When installed, such barriers prevent or substantially minimize ingress of flood waters within the height limits of the barrier panels. Examples of such barriers are seen in Smith (U.S. Pat. No. 7,523,589), disclosing a frame with scissor jacks to extend the sides and covered with a metal panel, Petty (GB Pat. 2,114,197), disclosing a hinged frame installed in a bag of extensible material, such that depressing the activator mechanism extends the sides laterally to lock the frame in the doorway or window.
Buss (DE Pat. 4,023,286) discloses a barrier formed of a frame that is mounted into the base of an opening and comprises threaded supports to press a seal against the soffit of the opening. Harrison (U.S. Pat. No. 6,427,396) and Russell (U.S. Pat. No. 5,943,832) each discloses a scissor jack allowing for lateral sliding of support members to fit a or door frame and includes a front panel cover to access to the scissor adjusting mechanism.
Other attempts for more permanent flood water barriers generally require permanent fitments, such as channels or anchor wells, disposed in the doorway for receiving a gate or panel, such as Iskra (GB Pat. 2,114,199) and Lawrence (GB Pat. 2,254,639). However, permanent channels and anchor wells are subject to wear from vehicles and weather, and can damage the fitment thereby reducing sealing and allowing for potential water intrusion. Further, permanent fitments can be unsightly, and can damage the opening since the channel or anchor well requires drilling into the opening's frame, base, or structure's slab. This compromises the stability of the structure, from minor reductions in structure results in deterioration in structural integrity or serious damage to the structural walls.
As such, an unmet need exists in the art for a watertight barrier of a building that can resist significant hydrodynamic forces while concurrently not compromising the structural integrity of the building.
The invention provides for a watertight barrier, comprising at least one extendable anchor and at least one flood gate. The anchor member is formed of aluminum, stainless steel, surgical steel, plastics. Useful aluminums include alloys, such as 2024, 6061, and 7075 aluminum. Plastics can include nylon, polyphenylene sulfide, polyetheretherketone, polyetherimide, polyamideimide, or fiber-reinforced plastics, such as carbon fiber, fiberglass, or aramid fiber in a matrix. Useful matrixes include, but are not limited to, epoxy, vinyl ester, and polyester.
The one or more flood gates include a gate main panel with a silicone seal disposed at least on the bottom edge of the gate main panel. Where the gate main panel is used without an extendable gate panel, the silicone seal is disposed around the bottom edge and the vertical edges, either as a single seal or as multiple seals, each disposed on an edge of the gate main panel. Where the gate main panel is used with one extendable gate panel, the silicone seal is disposed around the bottom edge and the vertical edge opposite the extendable gate panel. Where gate main panel is used with two extendable gate panels, the silicone seal is disposed around the bottom edge only. The extendable gate panel is slidingly connected to the gate main panel and includes a silicone seal along the bottom and outer edge of the extendable gate panel, or a silicone seal is disposed on the bottom edge and a second seal is disposed on the outer edge of the extendable gate panel. An extension panel seal is disposed on the outer face of the gate main panel or the interior face of the extendable gate panel, such that the extension panel seal fits between the gate main panel and the extendable gate panel. The interior of the gate main panel optionally includes cross beam supports, foam insulation, or spray insulation. In other variations of the invention, the flood gates include a gate main panel and at least one extendable panel. The main gate and at least one extendable panel include at least one silicone seal on the bottom edge of the panel that acts as a lower silicone seal that provides a water-tight seal on the lower edge of the flood gate. The main gate panel further includes a gate seal on its first vertical edge, allowing the main gate panel to form a watertight seal with the at least one extendable panel, while concurrently permitted the at least one extendable panel to slide from a retracted position to an extended position. Main gate panel includes a silicone seal on the second vertical edge to engage the building structure, where one extendable panel is used, or a second gate seal where a second extendable panel is used. If the gate uses only one extendable panel, the silicon seal on the second vertical edge is either integrated with the lower silicone seal or a separate silicone seal disposed on the second vertical edge. The at least one extendable gate panel further includes a first panel seal disposed on a first vertical edge of the at least one extendable gate panel to engage the building structure. Where two extendable gate panels are used, the second extendable gate panel includes a second panel seal disposed on a second vertical edge of the second extendable gate panel to engage the building structure. The gate further includes an extension mechanism disposed in the gate main panel and adapted to extend the at least one extendable gate panel, or extend both the first and second extendable gate panels, where present.
The panels are optionally made of aluminum, stainless steel, surgical steel, carbon fiber, plastic. Specific variations are similar to those materials disclosed for the anchors. However, as the panels require less strength compared to the anchors, additional materials can be used. Additional examples include acrylonitrile butadiene styrene (ABS), high impact polystyrene (HIPS), acrylic (PMMA), cellulose acetate, cyclic olefin copolymer (COC), ethylene-vinyl acetate (EVA), ethylene vinyl alcohol (EVOH), polyvinylfluoride (PVF), polyvinylidene fluoride (PVDF), polytetrafluoroethylene (PTFE), polychlorotrifluoroethylene (PCTFE), fluorinated ethylene-propylene (FEP), perfluoroalkoxy polymer (PFA), polyethylenechlorotrifluoroethylene (ECTFE), polyethylenetetrafluoroethylene (ETFE), perfluoropolyether (PCPE), acrylic/PVC polymer, aromatic polyester polymers (liquid crystal polymer), polyoxymethylene (acetal), polyamide (PA, nylon), polyamide-imide (PAI), polyaryletherketone (PAEK), polybutadiene (PBD), polybutylene (PB), polybutylene terephthalate (PBT), polycaprolactone (PCL), polychlorotrifluoroethylene (PCTFE), polyethylene terephthalate (PET), polycyclohexylene dimethylene terephthalate (PCT), polycarbonate (PC), polyhydroxyalkanoate (PHA), polyketone (PK), polyester, polyethylene (PE), polyetheretherketone (PEEK), polyetherimide (PEI), polyethersulfone (PES), chlorinated polyethylene (CPE), polyimide (PI), polylactic acid (PLA), polymethylpentene (PMP), polyphenylene oxide (PPO), polyphenylene sulfide (PPS), polyphthalamide (PPA), polypropylene (PP), polystyrene (PS), polysulfone (PSU), polytrimethylene terephthalate (PTT), polyurethane (PU), polyvinyl acetate (PVA), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), and styrene-acrylonitrile (SAN).

The portable barrier gate of the present invention consists of flood gate 10 and extendable anchor 20. In a preferred embodiment, flood gate 10 is extendable, thereby allowing the flood gate to fit snugly into a structure opening. Where the structure opening has large dimensions, such as a garage door opening, the portable barrier gate can use more than one flood gate 10 to provide a watertight seal on the opening. As seen in
In the illustrated example, extendable anchor 20 is formed of upper anchor member 21a with integrated jack 23, gate interface 26, and lower anchor member 21b with base seal 22, which is optionally silicone. In some variations, extendable anchor 20 or upper anchor member 21a includes anchor interface plate 24, having a larger cross-sectional surface area compared to upper anchor member 21a, and upper base seal 22a, as seen in
Extendable anchor 20 can be a formed from rectangular hollow structural section (HSS) beam, an I-beam, or T beam. Optional materials for the extendable anchor are aluminum, stainless steel, surgical steel, carbon fiber, or plastic capable of withstanding compressive forces.
Optionally, upper anchor member 21a and lower anchor member 21b each include anchor member fixation aperture 28 that correspond to one another such that when upper anchor member 21a is connected to lower anchor member 21b, the corresponding anchor member fixation apertures align. A pin is inserted into anchor member fixation aperture 28, locking upper anchor member 21a to lower anchor member 21b.
In certain embodiments, gate interface 26 has an H-shaped cross section, forming a channel on either side of the interface, seen in
Extendable anchor 20 is extended to fit within the upper threshold and lower threshold of the opening using jack 23, such as a lever-style jack. However, the exemplary jack is a screw-style jacking system with a worm or screw drive 23a, with a rotational activator, 23b, shown in
