Discussions and depictions pertaining to these, if present, are presented as examples only and do not limit the applicability of other characteristics, unless otherwise indicated.

(20) In general, the invention described herein relates to a selectively engaged flood defense system that is configured to form an effective barrier against floodwaters. The apparatus 100 is configured to sealingly engage with a potential entryway 102. The entryway may be defined as a doorway, hallway, window, or other point of physical entry (whether via a person or other matter) to where flood waters may enter through.

(21) In reference to FIGS. 1-7, the apparatus is illustrated in an embodiment of the present design. A flood barrier portion 104 constructed of a sufficiently rigid material is provided. A double-faced steel panel with polyurethane core is the preferred material to be utilized with the present invention. The material may be high-density polyethylene (HDPE) or a similar suitable material resistant to forces generated by the water, as well as oxidation and other detrimental effects inherent in regions where flooding is common. The barrier portion 104 is dimensioned to sealingly engage with the entryway 102. Each barrier portion 104 is comprised of an exterior side 106 and interior side 108. A plurality of apertures 110 are positioned along a perimeter substantially near each edge (113, 114, 115, 116) of the barrier portion 104.

(22) In specific reference to FIG. 2 and FIG. 5, a seal 118 is positioned central in relation to the apertures to provide a sealed engagement with an entryway gasket 120. To effectively seal the entryway, the seal 118 and entryway gasket 120 are similarly dimensioned to sufficiently contact one another. Each of the seal and gasket may be constructed of a rubber, or another suitable material commonly used in the arts.

(23) Each aperture 110 receives a fastener 122 therethrough as shown in FIG. 4. The fasteners 122 engage with receivers 124 positioned along a surface of the entryway frame 126. In a preferred embodiment, each fastener 122 is a threaded member configured to threadingly engage a corresponding receiver having threads therein. Once each fastener 122 is engaged with the corresponding receiver 124 the pressure provided therefrom is sufficient to provide a sealed engagement between the seal 118 and entryway gasket 120. In an embodiment, the sealed engagement results in a positive sealing pressure exceeding pressure caused by floodwater and other intrusive objects, effectively sealing the door.

(24) In an embodiment, each machine screw 124 threadingly engages a tapped insert 122. Once machine screw is removed, a cap screw is engaged with the tapped insert 122 to protect from corrosion and foreign materials entering the receiver.

(25) In a preferred embodiment and as illustrated in FIG. 6, a brace assembly 200 is engaged with the exterior side of the barrier 104 comprised of a substantially vertical member 202 and substantially horizontal member 204. The vertical member 202 is affixed to the exterior side 106 while the horizontal member 204 contacts the ground or other support. At least one brace 206 extends between each member to provide support to the apparatus 100 during stressful flood conditions. To provide adequate support, the brace assembly 200 is constructed of sufficiently rigid material such as a metal, metal alloy, or high-density plastic such as HDPE.

(26) In a preferred embodiment, the brace assembly 200 is fastened to a concrete slab exterior to the structure using masonry inserts 212. Once the brace assembly is removed, the masonry insert receivers 304 receivers are protected from corrosion and foreign materials with a cap screw 308.

(27) In use, when water is present on the exterior side 106 of the assembly 100, leakage through the entryway is prevented by the effective engagement of the barrier portion and the entryway as described above. Before a flood event, a user may procure a barrier portion, entryway frame, and fasteners. The user positions the barrier portion with the exterior side to the oriented to the exterior of a structure. The frame is affixed to the entryway, or the entryway may be provided with the frame permanently affixed thereto. Apertures are aligned with the receivers and fasteners are positioned therethrough to threadingly engage the harder and frame. The user may then ensure a sealed engagement between the gasket and seal has been made. After flooding has ceased or the threat thereof has ended, the barrier may be removed by unthreading the fasteners from the receivers and removing the barrier from the entryway.

(28) In an alternate embodiment, the user may procure the brace assembly and affix the brace assembly to the exterior side of the barrier portion. The brace assembly is configured to provide additional support to the assembly 100 to ensure that the strong forces resulting from flood waters do not compromise the structure of the assembly, structure, or entryway.

(29) In an alternate embodiment, the top edge 113 of the barrier portion may not have a rubber seal, leaving the bottom 115 and side edges 114, 116 having the rubber seal. The top edge 113 may not have a plurality of apertures disposed thereon. As a result, the user only fastens the bottom 115 and side edges 114, 116.

(30) In an instance where the entryway 102 is too large for a single barrier portion 104, any number of barrier portions may be affixed to one another at an edge (113, 114, 115, 116) utilizing secondary fasteners. In this manner, the user may construct a barrier of any size for a multitude of entryway 102 sizes and configurations.

(31) FIG. 8 illustrates a structure 800 having the entire entryway embodied as a door and window 804 covered by the barrier system as described above. In embodiments, the system may be provided in a multitude of sizes and shapes to effectively cover entryways as illustrated in FIGS. 10-13. FIG. 9 illustrates the similarities between a door and window system having similar components to engage with the exterior of the entryway. Both the full doorway and window barrier systems may be installed in a similar manner as embodiments described hereinabove, as illustrated in FIG. 10 and FIG. 11. Each may be provided with, or without a brace assembly when affixed to the structure 800.

(32) In reference to FIGS. 12 and 13, the barrier system is illustrated engaged and engaging with a garage door entryway 1200 or similar large entryway. As described above, one skilled in the art may appreciate that the barrier system may be provided in any shape or size that may effectively engage with an entryway to prevent flood waters from entering a structure. The barrier system affixes to the frame 1210 of the garage door entryway 1200 as well as a horizontal girt 1220 affixed between each side of the frame 1210. The girt 1220 has a plurality of fasteners and receivers to removably engage the barrier system thereto.

(33) In an embodiment, the girt 1220 may function as a fastening means for an upper garage door barrier assembly such that the entire garage door may be covered by the barrier assembly system. Although not specifically shown in FIG. 13, the assembly may be configured in a similar manner as FIG. 7 and/or FIG. 8 above.
