SMOKE GUARD DEVICE AND ACCESSORIES
A smoke-barrier device for under-door gaps is taught. A basic barrier comprises a unit of expandable/compressible material covered by one end of a length of fire-resistant and smoke and gas impermeable material, and is sized to completely seal the mandated gap beneath doors in the event of a fire. Another style includes magnetic material on the other end of the length of fire-resistant, moisture and gas impermeable material to further adhere the barrier to a metal door. Intumescent material may be fixed on the central part of the length of fire-resistant, moisture and gas impermeable material. The device is sized to fit commercial and private doors spaces and is offered in a kit including tape to place about top and sides openings of a door, luminescent tape to be placed on a window in the room, and a flashlight of various styles. The fire-resistant material may also be water impermeable.
1 . A device constructed of compressible/expandable material covered by a first end of a length of fire resistant cloth, said device so arranged that when said first end is inserted into a gap between the bottom of the door and the floor said device prevents smoke, poisonous gases, or fire from traversing the gap.
2 . The device, as recited in claim 1 , wherein said compressible/expandable material is foam.
3 . The device, as recited in claim 2 , wherein said foam is memory foam.
4 . The device, as recited in claim 1 , wherein said fire resistant cloth is impermeable to smoke and gas.
5 . The device, as recited in claim 4 , wherein said fire resistant cloth is impermeable to moisture.
6 . The device, as recited in claim 1 , further comprising intumescent material affixed to said device.
7 . The device, as recited in claim 1 , wherein a second end of said length of fire resistant cloth includes magnetic material arranged so as to attach said second end of said length of fire resistant cloth to a magnetic metal section of a door.
8 . The device, as recited in claim 7 , wherein said magnetic material is a piece of magnetic metal fixed to said second end of said length of fire resistant cloth.
9 . The device, as recited in claim 7 , wherein intumescent material is affixed to a central area of said length of fire resistant cloth.
10 . The device, as recited in claim 9 , wherein said intumescent material is self-adhering.
11 . The device, as recited in claim 1 , further comprising a second end of said length of fire resistant cloth comprising adhesive arranged so as to adhere second end of said length of fire resistant cloth to the door.
12 . The device, as recited in claim 1 , in combination with strips of self-adhering luminescent tape sized to be secured over door top and side openings.
13 . The device, as recited in claim 1 , wherein said device is rated for either one or two hours according to UL1784.
14 . The device, as recited in claim 1 , further comprising a carrying case for said device.
15 . The device, as recited in claim 1 , further comprising a carrying case for said device permitting said device to be folded for easy insertion into a suitcase.
16 . The device, as recited in claim 1 , in combination with strips of self-adhering luminescent tape sized to be secured over a window giving notice to fire-fighters.
17 . The device, as recited in claim 1 , in combination with a flashlight or a glow light giving notice to fire-fighters.
18 . The device, as recited in claim 1 , wherein said device is sized to fit with a hollow door to be released from the door in the event of a fire.
19 . A device constructed of a length of fire resistant cloth having a first end and a second end, said first end wrapped about and affixed to a compressible/expandable material covered so that when said first end is inserted into a gap between the bottom of the door and the floor said device prevents any smoke from traversing the gap, said second end comprising either magnetic or adhesive adhering means so arranged as to adhere second end of said length of fire resistant cloth to the door, and a section of intumescent material affixed to a central area of said length of fire resistant cloth.
20 . A kit containing:
A device constructed of a length of fire resistant cloth having a first end and a second end, said first end wrapped about and affixed to a compressible/expandable material covered so that when said first end is inserted into a gap between the bottom of the door and the floor said device prevents any smoke from traversing the gap, said second end comprising either magnetic or adhesive adhering means so arranged as to adhere second end of said length of fire resistant cloth to the door, and a section of intumescent material affixed to a central area of said length of fire resistant cloth, and strips of self-adhering luminescent tape sized to be secured over door top and side openings.
