Abstract:
A device and method for inhibiting the spread of a fire to the roof of a building by placing a base supporting a sprinkler on the roof. A hose connected to the base and in fluid communication with the sprinkler provides a source of water ejected from the sprinkler onto the roof. The interior of the base may be wetted to increase its weight. A rope, normally stored on a spool removably attached to the base, may be used to reposition the base on the roof.

BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     This invention relates to protection devices and methods used with buildings and, more particularly, to devices and methods for discouraging the spread of a wild fire to the roof of a building.  
         [0003]     2. Description of the Related Art  
         [0004]     The spread of wild fires to residential areas is a constant threat in many locations, particularly during dry seasons. Often such wild fires cause damage to many homes and buildings which are burned either from direct contact with flames or from embers spewed from the fire that fall on the roofs of homes and buildings and, sometimes from a long distance from the fire. Thus, such fires threaten destruction to large areas crowded with residential homes and other buildings.  
         [0005]     A variety of water systems for controlling fires which frequently occur on a dwelling or a building have been employed in the past. Such systems are disclosed in U.S. Pat. Nos. 5,263,543, 3,653,444, 3,754,600, and 6,360,968; all of which disclose elaborate sprinkler systems which may be installed on a roof top. Roof top systems are often a good tool for fighting a fire which has already started consuming the building, and may also be effective in preventing the fire from spreading to the building in the first place. They may also stop the fire from spreading to neighboring buildings.  
         [0006]     Roof top systems are bulky and take time to install on a roof. When the spread of a wild fire is imminent, there may not be enough time to order, deliver, and install a sprinkler system on the roof tops of buildings and single homes not already so equipped.  
         [0007]     When a wild fire threatens a certain area, firefighters have little option but to directly fight the fire itself, or take the necessary actions to address the threat of the fire spreading. A lack of manpower and adequate resources in many instances results in devastation of homes and buildings without any type of fire prevention or fire suppression equipment.  
         [0008]     Therefore, there is a long standing need to provide a fire prevention system that is inexpensive and can be quickly and easily delivered and installed in most buildings.  
         [0009]     It is a primary object of the present invention to provide a fire fighting device which can be quickly and easily implemented by mounting the device on the roof of a building.  
         [0010]     Another object of the present invention to provide a device which uses a regular garden hose to spray water on the roof of a building.  
         [0011]     Yet another object of the present to provide a lightweight and inexpensive device for preventing fire from spreading to a building.  
         [0012]     Still another object of the present invention is to provide an easily storable and transportable device for dousing a roof top with water to prevent ignition from burning embers generated by a near or distant ground fire.  
         [0013]     A further object of the present invention is to provide a device easily positionable at a selected location on a roof to discharge a spray of water onto the roof.  
         [0014]     A yet further object of the present invention is to provide an inexpensive method for soaking a roof with water to prevent ignition from flames and burning embers of an adjacent fire.  
         [0015]     A still further object of the present invention is to provide a method for quickly mounting a device on a roof for discharging a spray of water onto the roof.  
         [0016]     These and other objects of the present invention will become more apparent to those skilled in the art as the description of the present invention proceeds.  
       SUMMARY OF THE INVENTION  
       [0017]     The present invention relates to a device and to a method for fighting and/or preventing a fire in close proximity from spreading to and damaging a building. The device is lightweight, inexpensive, and can easily be mounted on the roof of the building in a few minutes. The device is hooked up to a regular garden hose to discharge a spray of water and soak the roof with water. Thus, the fire will be less likely to spread to the soaked roof of the building, and may also prevent the fire from spreading to neighboring buildings.  
         [0018]     The device includes a mounting base supporting a conventional lawn sprinkler and plumbing for conveying water to the sprinkler with a regular garden hose connected to the base. The device is mounted on the roof by tossing a line or rope over the roof and then throwing the device itself onto the roof. This places the device on the roof with the rope on one side of the roof and the garden hose on the other side of the roof. Two people pulling on the hose and the rope from each side of the roof position the device on the roof. Once positioned, a hose faucet connected to the hose is opened to cause water flow to the sprinkler and spray the roof.  
         [0019]     In one embodiment of the device, the base includes a water absorbing material wetted with water from the hose to increase the weight of the device and discourage it from moving in response to strong winds. The rope may be used to tether the device.  
         [0020]     The device is ideal for single family homes, especially single story buildings and may be used on flat or pitched roofs. The device can be installed in a matter of minutes without requiring a user to climb onto the roof or to use a ladder. It is preferably lightweight, to make it easier to mount it on the roof and it can be significantly weighed down after mounting by filling it with water. As a standard garden hose is used for the source of water it can be mounted by an average person and requires neither a firefighter nor a professional to mount. Once mounted, and the water faucet activated, the device may be left unmonitored to water the roof, and activities relating to evacuation may be undertaken. The device may be stored near the garden hose and faucet to have it is readily available, especially during periods of high fire danger. It can also be installed by a firefighter or a neighbor, in case a resident of the home is out. As the device is lightweight and inexpensive, firefighters can have a large supply of the devices on their trucks for use on homes potentially in the path of a spreading fire.

     DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0027]      FIG. 1  illustrates a roof soaking device  10  located on roof  12  of a building  14 , such as a home. The device has a mounting base  16  supporting a sprinkler  18 . A hose  20  provides water to the sprinkler. A line or rope  22  extends from base  16  to aid in positioning the device on the roof.  
         [0028]     Referring particularly to  FIGS. 2 and 3 , base  16  has an outer cover  24  formed from a material impermeable to water, such as a vinyl or other plastic, and a water absorbing filling  26 . The filling may be a sponge pillow(s) inside the outer cover to give the base its form. Though illustrated as being generally square, base  16  may be of a variety of different geometric shapes. The base is lightweight and weighs in the order of less than ten pounds and may weigh in the range of two and five pounds. Such light weight will enable an individual of average strength to toss the device onto the roof of a single story building.  
         [0029]     Sprinkler  18 , which may be a commercially available sprinkler providing a continuous or an oscillating spray pattern, may include a circular wide head  28  and a base  30 , interconnected by a narrow neck  32 . The neck extends through an aperture  34  in top surface  36  of cover  24 . The diameter of aperture  34  is intermediate the diameter of the neck and the diameters of the sprinkler head and its base. Manufacturers providing suitable sprinklers include companies referred to as Orbit and Rainbird (both of which are registered trademarks). A variety of sprinklers other than the type illustrated, may be mounted on the base.  
         [0030]     A pipe  40  is attached to sprinkler  40 , such as at neck  32 , to provide fluid communication between the pipe and the sprinkler. The pipe lies beneath cover  24  and extends to and through an opening  41  in side  42  of base  16 . A conventional hose coupling  44  is at the terminal end of the pipe. The pipe generally lies above filling  36  and serves to hold the sprinkler in place. Holes  46  dispersed along the pipe permit water to seep into the filling in the base. The weight of the water absorbed by the filling increases the weight of the device and it becomes less likely to be moved by the wind. A water hose  20  (see  FIG. 1 ) or other water source is attached to coupling  44  to convey water to sprinkler  18  via pipe  40  and coupling  44 .  
         [0031]     As shown in  FIGS. 2 and 4 , rope  20  is coupled to base  16 , generally on a side opposite coupling  44 , and attached to ring  54  secured by strap  50 . A spool  46  about which the rope is wrapped is attached to top surface  36  of the base by a strap segment  52 . Strap  50  may be sewn to the cover  24  by a stitching along the strap. Strap segment  52  wraps about the spool to retain the spool attached to base  16 . Ring  54  may be secured between strap  50  and top surface  36  of cover  24 , as shown. The length of the rope  20  should be greater than at least half the height of the top of building  14  to allow an individual of average height standing on the ground to grasp the spool end of the rope when device  10  is positioned on the roof.  
         [0032]     Device  10  may include handles formed by further straps  60 ,  62  attached to base  16 . A yet further strap  64  may be attached to the base to extend across pipe  40 . It is to be noted that straps  50 ,  60 ,  62 ,  64  and strap segment  52  may be formed from a single strap. The free end of strap segment  52  forms a loop for partially encircling spool  46  and is held in place by a latch  66 , as shown in  FIGS. 2, 4  and  4 A. When the device is used, latch member  23  is opened, to release the spool. The latch member includes an elongated turning knob  60 , which may be inserted in an elongated aperture  70  of a plate  72  attached to strap segment  52 . Knob  24  is turned to engage the strap segment and retain the spool and turned again to permit disengagement and release of the spool.  
         [0033]     Before mounting device  10  on a roof, a garden hose  20  is connected to coupling  44  and spool  46  is released from strap segment  52 . The spool, with rope  22  unraveling therefrom is tossed over roof  12  of building  14 . Device  10 , with the attached hose, is thrown onto the roof. This will place base  16  on the roof with the rope dangling from the roof on the other side of the building.  
         [0034]     When device  10  has been placed on the roof, with hose  20  and rope  22  on opposite sides of the building, two people pulling on the hose and the rope, respectively, can position the device to a selected location on the roof. Once positioned, the hose faucet is turned on to convey water to base  16  and distribute it through the sprinkler to spread the water on the roof. Rope  22  may also be tied to a part of the house to tether the device and prevent it from being moved by strong winds.  
         [0035]     Upon turning on the water faucet, filling  26  inside base  16  of device  10  fills with water to weigh down the base. This additional weight helps to prevent the device from moving in case of strong winds. The maximum weight of the base once filled to capacity is in the order of between eight and twenty pounds, and more specifically between ten and fifteen pounds. Also, additional straps or ropes attached to one or more of handles  60 ,  62  may be provided to tether the device to keep it from moving.  
         [0036]     Device  10  is light weight, inexpensive, and can easily be mounted on the roof of a building. Once mounted, the device can be used to soak the roof of the building with water. The wetted roof will be less likely to catch on fire and it may even serve in the capacity of a fire break to prevent a spread of the fire past the building.  
         [0037]     The device is ideal for single home structures, especially single story structures, and may be used on any type of roof, whether flat or pitched. The device can be installed in a matter of minutes without having to climb onto the roof nor does it require the use of a ladder. Since the device is relatively light weight, little effort is needed to mount it on a roof. Since the device can be significantly weighed down after installation by filling it with water, it will remain on the roof, even in high wind conditions. The device fits a standard garden hose, and can be installed and mounted by an average homeowner and does not require a firefighter or a professional for installation. The device in the operating mode may be left unmonitored to water the roof while the house or building is being evacuated. The device may be stored near a garden faucet readily available for use, by the homeowner, a firefighter or a neighbor. Furthermore, since the device is light weight and inexpensive, firefighters can have a large quantity of the devices on hand for installation on a large number of homes when the spread of a wild fire to the homes is imminent.
