BACKGROUND OF THE INVENTION

This invention relates generally to the field of fire suppression devices and more specifically to a fire control enclosure.

In an ongoing attempt to prevent wildfires from spreading, the idea of controlled burns has become popular. A controlled burn creates a section of ground where flammable materials have been eliminated so that a fire would have to jump over the bare ground to access adjacent burnable materials.

Such open burning conditions are problematic with presently available equipment and tools as even while practicing known safe control burn techniques, sizable risk of fire jumping over the controlled burn remains. Therefore, it would be helpful to have an easy to deploy fire resistant structure that could cover the control burn area preventing embers from flying to other areas having ignitable material.

BRIEF SUMMARY OF THE INSTANT INVENTION

The primary object of the invention is to provide a novel fire control enclosure that allows fire professionals to safely create a fire break in foliage or other flammable material without risk of having the fire accidentally spread to other areas.

A further object of the invention is to provide a fire control enclosure that can be air lifted to fire locations.

Other objects and advantages of the present invention will become apparent from the following descriptions, taken in connection with the accompanying drawings, wherein, by way of illustration and example, an embodiment of the present invention is disclosed.

In accordance with a preferred embodiment of the invention, there is disclosed a fire control enclosure comprising: a telescoping rigid structural frame assembly, flame retardant fabric, a plurality of wheels, a plurality of smoke exhaust outlet pipes, the telescoping rigid structural frame assembly that can be formed into an elongate structure comprising a plurality of frame members, thet frame members comprising a plurality of equally spaced vertical support poles and roof support joists, the telescoping frame members being horizontally disposed and forming the basis of the roof support joists, the side walls, a roof cover, end walls and a drag sheet constructed of the fire retardant fabric attached to the frame members to form an enclosed structure. The smoke exhaust outlet pipes being attached to the roof support joist and through apertures in the roof cover; the wheels being attached to the bottom end of the vertical support poles, and the telescoping rigid structural frame assembly and the flame retardant fabric capable of compressed for storage or expanded for use. The drag sheet capable of extending from the distal end of said enclosure to an area essentially equal to the length of the enclosure, enabling the drag sheet to cover the section of ground that has just been ignited, to ensure that any residual fire be eliminated and no embers can fly to out from the controlled burn area as the deployed fire enclosure is moved forward.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Detailed descriptions of the preferred embodiment are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner.

Referring now to FIG. 1 we see a perspective view of the embodiment 100. A fire-resistant cover 2, 36, 8 creates an enclosure that can be used to enclose controlled burns for fire safety concerns. Exhaust pipes 6 allow smoke to escape. Alternatively, the exhaust pipes may be closed, wherein the fire control enclosure then can be located over a fire, exhausting the oxygen within the fire control enclosure, therefore extinguishing the fire. Apertures 12 allow a person to insert the nozzle 32 of a blow torch to ignite a fire within the enclosure. The apertures are covered with a fire-resistant flap 30 which is attached at its top edge as shown in FIG. 6. Drag sheet 10 is attached to the distal end of the enclosure and is essentially a similar length to the enclosure so that when the enclosure is rolled forward on metal wheels 4, the recently burned area is covered by the drag sheet 10 to ensure that all fire in that area is extinguished. The fire-resistant cover is made of light weight material developed by NASA for extreme temperature conditions. It is called Beta Cloth. Beta cloth is a type of fireproof silica fiber cloth used in the manufacture of Apollo/Skylab A7L space suits, the Apollo Thermal Micrometeoroid Garment, the McDivitt Purse and in other specialized applications. Beta cloth consists of fine woven silica fiber, similar to fiberglass. The resulting fabric will not burn and will melt only at temperatures exceeding 650° C. (1,200° F.). To reduce its tendency to crease or tear when manipulated, and to increase durability, the fibers are coated with Teflon.

A tight weave of Beta cloth makes it more durable against atomic oxygen exposure. Its ability to resist atomic oxygen exposure makes it commonly used as the outer-most layer in multi-layer insulation for space, and it was used significantly on the Space Shuttle and the International Space Station. It was implemented in NASA space suits after the deadly 1967 Apollo 1 launch pad fire, in which the astronauts' nylon suits burned through. After the fire, NASA demanded any potentially flammable materials were to be removed from both the spacecraft and space suits. Beta cloth was developed by a Manned Spacecraft Center team led by Frederick S. Dawn and including Matthew I. Radnofsky working with the Owens-Corning and DuPont companies.

FIG. 2 is a perspective view of the interior of the enclosure with the front and rear panels and the drag sheet removed for clarity purposes. This view shows vertical support rods 14 as well as telescoping horizontal structural members 22, 18, 20 and the roof joist members 16. The telescoping principle is shown in FIG. 3 as fully extended use position and FIG. 4 as compressed to its storage position where smaller diameter tubes 28 can slide into or out of larger diameter tubes 26.

The tubes are made of light weight metal such as 6061 aluminum.

FIG. 5 is a perspective view of the embodiment 100 in the compressed, or stored position. All telescoping support tubes are compressed, and the flexible fire-resistant fabric 2 is folded accordion style to take up very little room. Drag sheet 10 is rolled up and stored. Wheels 4 are abutting each other and exhaust pipes 6 are also in close proximity to each other.

FIG. 6 is a perspective view of the embodiment 100 with the front cover 8 removed. Internal flaps 30 can be seen covering apertures 12. A user can insert the nozzle 32 of a blow torch to ignite a fire within the enclosure of the embodiment 100. The user can also temporarily push flap 30 aside to view conditions within the enclosure 100.

FIG. 7 is a partial section view showing exhaust pipe 6 having internal steel wool type baffling to ensure the collection of all embers as they try to escape the enclosure 100. The inverted J shape of the exhaust pipe 6 further reduces the chance of smoke and embers being blasted into the upper atmosphere.

FIG. 8 is a perspective view of the embodiment 100 being loaded or removed from a flatbed truck. Its relatively light weight makes it easy to maneuver.

FIG. 9 is a perspective view of the embodiment 100 being used as an enclosure for a vehicle fire. A fire department can quickly deploy the embodiment to cover a burning vehicle and thereby contain any fire and also help eliminate the fire be reducing the amount of available oxygen allowed to surround the vehicle.

FIG. 10 is a perspective view of the embodiment 100 where the flaps of the front and back of the enclosure 100 allow the enclosure 100 to be rolled over the fence so that a control burn fire can be set on either side of the fence without danger of embers flying to surrounding areas.

FIG. 11 is a perspective view of the embodiment 100 being lifted by a fleet of drones 44 so that it can be deployed and dropped in a controlled manor in a fire zone to help extinguish unwanted fires in remote locations.
