  "abstract": "A device to secure a door chock to an industrial helmet more particularly a firefighter's helmet.",
  "claims": [
    "1. A device to secure a door chock to an industrial helmet comprising: an L-shaped body having a relatively flat planar vertical section and a relatively flat planar horizontal section; a clamp; means in which to secure said L-shaped body to said clamp; and means in which to secure said door chock to the L-shaped body; wherein said flat planar vertical section further comprises raised side walls extending outwards from said flat planar vertical section; wherein said raised side walls create a snug fit when said door chock is positioned in said device; and wherein said helmet is a firefighter's helmet having a brim.",
    "2. The device according to claim 1, wherein securing said means in which to secure said door chock to the L-shaped body is selected from the group consisting of bungee cord, cable tie, circle cotter, cord, cotter pin, hairpin clip, knockout ring, o-ring, R-clip, rope, rubber band shock cord, helical or coil spring, strap, twine, thread and wire.",
    "3. The device according to claim 1, further comprising one or more pairs of horizontal cuts into the planar vertical section, wherein each of the pair of horizontal cuts are forged into opposing sides of said planar vertical section; wherein said cuts accommodate and secure an o-ring to said device.",
    "4. The device according to claim 1, wherein said clamp is a c clamp screw compressor clamp having a serrated thumb screw head; wherein a side of said c clamp opposing a side with the thumb screw head is positioned over the brim of the helmet and the side with the thumb screw is situated below the brim so that when the thumb screw head turns, a lower portion of the clamp comes in contact with the brim of said helmet securing said device to said helmet.",
    "5. The device according to claim 1, wherein the planar horizontal section comprises a bore hole and a side of a c clamp opposing a thumb screw comprises a bore hole.",
    "6. The device according to claim 5, wherein said bore hole in said planar horizontal section traverses an entire width of said planar horizontal section and is an elongated mount hole.",
    "7. The device according to claim 5, wherein side walls of the bore hole of the planar horizontal section and side walls of the bore hole in the c clamp are threaded.",
    "8. The device according to claim 1, wherein said L-shaped body is secured to said clamp with a screw.",
    "9. The device according to claim 8, wherein said screw is capable of moving said L-shaped body across said clamp so as to position said L-shaped body closer to or farther away from the helmet to which said device is mounted and then securing said device to said helmet when an optimal positioning of said device has been determined.",
    "10. The device according to claim 1, wherein said L-shaped body is forged as a single unit or the flat planar vertical section and the flat planar horizontal section are manufactured separately and then fused together.",
    "11. The device according to claim 1, wherein the L-shaped body is manufactured from a material selected from the group consisting of high polymer resin, ceramic, a metal and any combination thereof, provided said material is impact and chemical resistant, anti-static, resistant to chemicals, lightweight, waterproof and up to 500° heat resistant.",
    "12. The device according to claim 11, wherein said L-shaped body is manufactured from iron, aluminum, copper, carbide, cermet, stainless steel, polymide-imide (PAI), poly ether imide (PEI), polyacetal (POM), poly phenylene sulfide (PPS), poly ether ether ketone (PEEK), poly tetra fluoro ethylene (PTFE), polymide 6 (PA6), polyethylene (PE), polypropylene (PP), vinyl chloride resin (VC), polystyrene (PS), polyethylene-telephthalate (PET), acrylonitrile butadiene (ABS) and any combination thereof.",
    "13. The device according to claim 12, wherein said L-shaped body and said clamp are formed from durable and lightweight aluminum or stainless steel or a steel alloy.",
    "14. The device according to claim 1, wherein said device may be mounted on both traditional and modern style firefighter helmets.",
    "15. The device according to claim 1, wherein a width of the L-shaped body is between 1 to 2 inches and a length of the planar vertical section is 5½ inches and a length of the flat planar horizontal section is between 1¼ to 1¾ inches.",
    "16. The device according to claim 1, wherein said L-shaped body further comprises one or more holes."

  "description_excerpt": "Firefighters are routinely confronted with unpredictable situations. In addition to carrying tools such as axes and crowbars, a firefighter must often hold, transport and operate a fire-hose nozzle for prolonged durations. In many instances, a firefighter encounters self-closing doors which are prevalent in apartment buildings, public schools, hospitals, offices and many other buildings. These doors impede a firefighter's entry into a room causing a potentially dangerous delay.\n\nOne of the most valuable tools used by a firefighter is a door chock (also known as a door stop or door wedge) which enables the firefighter the ability to keep such self-closing doors open while he/she moves equipment from one room to the next. If a large building is on fire, the firefighter may have to use the door chock several times as he/she moves from one room to the next. It is imperative that the firefighter can access his/her door chock at all times.\n\nCurrently, firefighters retain their door chock on their helmet using a large rubber band that fits around their helmet. There are several problems associated with the use of a standard rubber band. First, not all fire helmets are designed the same so one rubber band may not be as useful for one helmet as opposed to another. Second, it may be difficult, particularly when the firefighter is wearing gloves, to access the rubber band to release the door chock and then secure it again behind the rubber band particularly when the rubber band is wet or covered in flame-retardant foam.",
