CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is related to application number (docket AAFP-Po2), filed 27 June 20o6 and entitled "Fire Sprinkler", which is incorporated in its entirety by this reference.
TECHNICAL FIELD
[0002] This invention relates generally to the fire suppression and extinguishment field, and more specifically to a new and improved sprinkler system and method of installation in the fire suppression and extinguishment field.
BACKGROUND
BACKGROUND
[0003] Fire sprinkler systems have been used in the United States to protect warehouses and factories for over one hundred years. Fire sprinkler systems are positioned near the ceiling of a room where hot "ceiling jets" spread radially outward from a fire plume. When the temperature at an individual sprinkler reaches a pre-determined value, the thermally responsive element in the sprinlder activates and permits the flow of water as a water jet through an orifice toward a deflector. The metal deflector redirects the water jet into thin streams or "ligaments" that break up into droplets due to surface tension. The water droplets serve three purposes:
(i) delivering water to the burning material and reducing the combustion rate, (2) -wetting the surrounding material and reducing the flame spread rate, and (3) cooling the surrounding air through evaporation and displacing air with inert water vapor.
(i) delivering water to the burning material and reducing the combustion rate, (2) -wetting the surrounding material and reducing the flame spread rate, and (3) cooling the surrounding air through evaporation and displacing air with inert water vapor.
[0004] A typical sprinlder has a coverage area of 200 ft2 (18.5 m2), which is typically measured in a circular pattern with a radius of 8 feet (2.5 m) or in a square pattern with equal sides of 14 feet (4.25 m). A typical metal building includes at least three beams, such as rafters, extending along the width of a space and separated from each other by a distance of 25-30 feet (7.5m to gm). As shown in FIGURES
and 4, a conventional fire sprinlder system for a typical metal building includes four supply lines, each with four typical sprinklers.
and 4, a conventional fire sprinlder system for a typical metal building includes four supply lines, each with four typical sprinklers.
[0005] From a labor and materials viewpoint, the installation of every individual supply line is an additional cost. An additional supply line requires additional labor, as the installers of the fire sprinlder system must fasten each supply line to a structural member near the ceiling, which typically requires the use of a ladder or a platform. An additional supply line also requires additional metal, which is the typical material for the supply lines. Thus, there is a need in the fire suppression and extinguishment field to create an improved sprinkler system and method of installation that reduces the labor and/or materials costs. This invention provides such improved sprinkler system and method of installation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0011] The following description of the preferred embodiments of the invention is not intended to limit the invention to these preferred embodiments, but rather to enable any person skilled in the art of fire suppression and extinguishment to make and use this invention.
[0012] As shown in FIGURES 1 and 2, the fire sprinlder system lo of the preferred embodiments includes a supply line 12 and a series of sprinklers 14 connected to the supply line 12. The fire sprinkler system lo of the preferred embodiments is preferably installed in a space having a width Wi of at least 20 feet (6m) and a length Li of at least 20 feet (6m), and is more preferably installed in a space having a width of at least 20 feet (6m) and a length of approximately 25-30 feet (7.5m to gm). The space is preferably defined by two beams 16 extending along the width of the space and separated by a distance equal to the length of the space. The beams 16 function to support the weight of the roof (shown in FIGURE 5). The beams 16 are preferably steel I-shaped rafters 16, but the beams 16 may be any suitable structural member to transfer the weight of the roof, may be made from any suitable material, and may be shaped in any suitable manner. The height of the space is preferably 20 to 40 feet (6 to 12m), but may alternatively be any suitable height. In a variation of the preferred embodiment, the space may include a series of purlins :18 extending the length of the space and separated by a distance of approximately feet (1-2m). The purlins 18, which span lengthwise between the rafters 16 and are fixed onto the rafters 16, function to support the weight of the roofing sheets (not shown) of the roof. The purlins 18 are preferably steel Z-shaped purlins 18, but the purlins 18 may be any suitable structural member to support the roofing sheets of the roof, may be made from any suitable material, and may be shaped in any suitable manner. Preferably, the fire sprinlder system io is installed in a metal building (such as a prefabricated metal building), but the fire sprinkler system io may alternatively be installed in any suitable shelter.
[0013] The supply line 12 of the preferred embodiments functions to supply a fire suppressing or extinguishing substance to the sprinlders 14. The supply line 12 preferably supplies water to the sprinlclers 14, but may alternatively supply any suitable substance that suppresses or extinguishes fires. The supply line 12 preferably extends along the width Wi of the space, and is preferably located between the beams i6. More preferably, the supply line 12 generally bisects the distance between the beams 16.
[0094] As shown in FIGURES 2 and 5, the series of sprinklers 14 of the preferred embodiments function to disperse the fire suppressing or extinguishing substance in a coverage area having a length L2 and a width W2. Preferably, the width W2 of each coverage area is less than the length L2 of each coverage area. In a first variation, the width W2 of each coverage area is less than 66% of the length L2 of each coverage area. In a second variation, the width W2 of each coverage area is less than 33% of the length L2 of each coverage area. In a third variation, the length L2 of each coverage area is at least 20 feet (6m) and the width W2 of each coverage area is approximately 5-6 feet (1-2m). In a fourth variation, the length L2 of each coverage area is approximately equal to the distance between the rafters 16 of the space, and the width W2 of each coverage area is approximately equal to the distance between the purlins 18. In alternative variations, the length L2 and the width W2 of each coverage area may be any suitable dimension.
[0015] Each sprinkler 14 of the preferred embodiments is connected to the supply line 12 and located along the supply line 12 such that the coverage areas of the sprinklers 14 overlap at least a significant portion of the space. Each sprinkler 14 is preferably oriented such that the length L2 of its coverage area extends in opposite directions toward the beams 16 and the width W2 of each coverage area extends to the two closest purlins 18. Locating the supply line 12 between the rafters 16 and orienting the sprinklers 14 towards the rafters 16 allows the fire sprinkler system 1o to be installed in a typically metal building with one-half of the supply lines of a conventional fire sprinkler system, which greatly reduces the labor and materials for the fire sprinkler system io. Although only one version is shown, the sprinkler 14 may be an upright-type sprinlder (above the supply line), a pendant-type sprinkler (below the supply line), or may alternatively be two horizontal-type sprinklers connected back-to-back.
[0016] In a variation of the preferred embodiments, as shown in FIGURES 6 and 7, each sprinkler 14 is located along the supply line 12 between two purlins 18 such that each sprinlder 14 generally bisects the distance between either the two closest purlins 18 or the closest purlin 18 and a wall2o or other structural member.
When the sprinlder 14 is located between two rafters 16 and between two purlins 18, it is generally centered within a volume 24 defined by a vertical extension of the rafters 16 on two sides, the purlins 18 on two sides, a first horizontal extension of the top of the purlins 18 (i.e., the roof 22) on one side, and finally a second horizontal extension of the bottom of the purlins 18. The hot "ceiling jets" that spread radially outward from a fire plume generally fills this volume 24. By centering the sprinlder 14 in this volume, the fire sprinlder system 1o may be able to respond faster to the fire.
[0017] As a person slalled in the art of fire suppression and extinguishment will recognize from the previous detailed description and from the figures and claims, modifications and changes can be made to the preferred embodiments of the invention without departing from the scope of this invention defined in the following claims.
