Abstract
A fire protection device for use in isolating a building structure having several sides from an external fire includes a plurality of folded fire-resistant protective covers and a releasing mechanism. Each protective cover has dimensions large enough to cover one of the several sides of the building structure. The protective covers are composed of knit, woven or nonwoven textiles composed of flame resistant fibers including cotton, polyester, polyamide, viscose, themoset fibers, inorganic fibers and carbon fibers with a fabric areal weight between 20 grams per square meter to 300 grams per square meter. The textiles are impregnated with a fire resistant material which absorbs heat, such as aluminum trihydrate (ATH) or other hydrated metal salts, borates, silicates, phosphates, bromides and chlorides, moisture absorbing polymers such as poly-acrylates and starch derivatives so that the amount of impregnated material is less than 50% of the fabric weight. The releasing mechanism releases each protective cover.

DESCRIPTION OF THE PREFERRED EMBODIMENT
[0069] Referring to FIG. 24 in conjunction with FIG. 25 a fire protection device 610 involves placing a fire resistant sheet material over a building to prevent the building from burning down in a surrounding fire. There is nothing more important with these types of fire protection devices than being able to quickly deploy them before a fire starts on the building to be protected. Often there is little warning of an approaching fire, especially in urban areas where the threatening fire starts in the next-door neighbor's house at night. Also, wild fires overtake rural buildings with amazing speed. Without the ability to quickly and completely deploy the fire protective sheet material, the building will succumb to tire before the sheet material can be deployed. A building 611 has a pitched roof 612 and perpendicular walls 614 and 619. Housings 616 and 617 are adjacent and parallel to the ridge 618 of the roof 612. Each of the housings 616 and 617 contains a cylinder upon which the sheet material 620 is rolled in order to compact the sheet material 620 within each of the housings 616 and 617. The sheet material 620 is folded in at least one location to define folded portions 622 and 624 before the sheet material 20 is rolled over the cylinder within each of the housings 616 and 617. Deployment or the compacted sheet material 620 is accomplished by lines 628 and 630 which are connected to the edges 632 and 634 of the folded portions 622 and 624, respectively. The user pulls on lines 628 and 630 to cause the sheet material 620 to be removed from housing 616, deployed over the roof 612 in its folded over condition and pulled to the ground 640 where it will later be secured. Each sheet material 620 is deployed over the wall 619 as well as the wall 614 by pulling on lines 628 and fastening edges 632 where they intersect with Velcro or other suitable means of securing these edges together against the wind caused by a fire. The same procedure is accomplished for the other wall by pulling lines 630 and securing the edges 634 together with Velcro. The result is a very quickly and completely deployed fire resistant sheet material 620 which will substantially prevent the building 611 from burning. The sheet materials 620 may be secured to the ground 640 by placing rocks 629 over the material which overlays the ground 640. In addition, a bar 641 may be sewn in the leading edge of each sheet material 620 to better secure each sheet material to the ground 40 and to better deploy the sheet material 620 from either of its housings 616 or 617.
[0070] Still referring to FIG. 24 in conjunction with FIG. 25 the fire protection device 610 is used in isolating a building structure 611 having several sides from an external fire. The fire protection device 610 includes a plurality of folded fire-resistant protective covers 710 and releasing mechanism 720. Each fire-resistant protective cover 711 has dimensions large enough to cover one of the several sides of the building structure 611. The fire-resistant protective covers/textiles 711 are composed of knit, woven or nonwoven textiles composed of flame resistant fibers including cotton, polyester, polyamide, viscose, themoset fibers, inorganic fibers and carbon fibers with a fabric areal weight between 20 grams per square meter to 300 grams per square meter. The textiles 711 are impregnated with a fire resistant material which absorbs heat, such as aluminum trihydrate (ATH) or other hydrated metal salts, borates, silicates, phosphates, bromides and chlorides, moisture absorbing polymers such as poly-acrylates and starch derivatives so that the amount of impregnated material is in the range of 30% to 50% of the fabric weight. The releasing mechanism 720 releases each protective covers 711.
[0071] From the foregoing it can be seen that a covering for protecting a building from fire has been described. It should be noted that the sketches are not drawn to scale and that distances of and between the figures are not to be considered significant.
[0072] Accordingly it is intended that the foregoing disclosure and showing made in the drawing shall be considered only as an illustration of the principle of the present invention.
