ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a fire protection system and more particularly pertains to deluging portions of a building which are not protected by means of fire retardant material such as windows and eaves.
2. Description of the Prior Art
The use of roof sprinklers is known in the prior art. More specifically, roof sprinklers heretofore devised and utilized for the purpose of protecting a roof from wild fires are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.
By way of example, the prior art includes U.S. Pat. No. 5,125,458 to Berman; U.S. Pat. No. 4,175,703 to Valiant; U.S. Pat. No. 4,453,155 to Cooper; and U.S. Pat. No. 4,428,434 to Gelaude.
In this respect, the fire protection system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of deluging portions of a building which are not protected by means of fire retardant material such as windows and eaves.
Therefore, it can be appreciated that there exists a continuing need for a new and improved fire protection system which can be used for deluging portions of a building which are not protected by means of fire retardant material such as windows and eaves. In this regard, the present invention substantially fulfills this need.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of roof sprinklers now present in the prior art, the present invention provides an improved fire protection system. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved fire protection system which has all the advantages of the prior art and none of the disadvantages.
To attain this, the present invention essentially comprises a building having a periphery with a roof situated thereon and a plurality of windows. The roof is supported by rafters which are angled downwardly from a ridge to at least one eave thereof. At least one eave extends beyond the periphery of the building a predetermined distance. It should be noted that the roof and the periphery are constructed from a fire retardant material. As shown in
FIG. 1
, a reservoir tank is included. Such tank comprises a cylindrical tank positioned distant the building above the ground. In use, the reservoir tank is adapted to contain a predetermined amount of water. With reference still to
FIG. 1
, a plurality of underground supply pipes are included each formed of PVC connected at a first end thereof to the reservoir. Such supply pipes extend to the building so that the water may flow from the reservoir tank to the building. Further provided is a plurality of above ground distribution pipes. Each above ground distribution pipe is formed of PVC with a metallic covering for protection against UV radiation. Note FIG.

. The above ground distribution pipes include at least one vertical pipe situated vertically on the periphery of the building, as shown in
FIG. 1. A
lower end of the at least one vertical pipe is connected to a second end of the underground pipe. The distribution pipes further include a plurality of horizontal pipes connected to an upper end of the vertical pipe and extended along the length of the at least one eave on an underside thereof. See FIGS.

, a plurality of rafter sprinklers are connected to the horizontal pipes of the above ground distribution pipes. Preferably, there is one rafter sprinkler for every two rafters. By this design, the rafter sprinklers are adapted to spray water upwardly towards the rafters upon the supply of water thereto. It should be noted that each rafter sprinkler has a first predetermined breadth of spray dependent on spacing between the rafters. Also included is a plurality of window sprinklers connected to the horizontal pipes of the above ground distribution pipes above each of the windows of the building. The window sprinklers are each adapted to spray water downward on to an associated window upon the supply of water thereto. Each window sprinkler has a second predetermined breadth of spray dependent on the width of the windows. A pump is included to effect the flow of the water from the reservoir tank through the pipes and to the sprinklers upon the receipt of an activation signal. For transmitting a heat detection signal upon a surrounding temperature surpassing a predetermined amount, at least one heat sensor is situated beneath the at least one eave. A reset switch is adapted to generate a reset signal upon the depression thereof. Finally, a controller is connected to the pump, the heat sensor, and the reset switch. In operation, the controller is adapted for transmitting to the pump an activation signal upon the receipt of a heat detection signal. The controller continues to transmit the activation signal until the receipt of the reset signal.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
It is therefore an object of the present invention to provide a new and improved fire protection system which has all the advantages of the prior art roof sprinklers and none of the disadvantages.
It is another object of the present invention to provide a new and improved fire protection system which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new and improved fire protection system which is of a durable and reliable construction.
An even further object of the present invention is to provide a new and improved fire protection system which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such fire protection system economically available to the buying public.
Still yet another object of the present invention is to provide a new and improved fire protection system which provides in the apparatuses and methods of the prior art some of the advantages thereof, while simultaneously overcoming some of the disadvantages normally associated therewith.
Still another object of the present invention is to deluge portions of a building which are not protected by means of fire retardant material such as windows and eaves.
Lastly, it is an object of the present invention to provide a new and improved fire protection system for a bu
