Fire extinguishing tool
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The field of invention relates to fire extinguishing apparatus, and more particularly pertains to a new and improved fire extinguishing tool wherein the same is utilized to impact fire and associated flames preventing oxygen access thereto. 
     2. Description of the Prior Art 
     Fire extinguishing apparatus of various types is utilized in the prior art to minimize damage associated with flame structure. A conventional manner of addressing such flames are associated with various liquid and mechanical structure to minimize access of oxygen to the flame and its propagation. 
     Accordingly, it may be appreciated that there continues to be a need for a new and improved fire extinguishing too as set forth by the instant invention which addresses both the problems of ease of use as well as effectiveness in construction and in this respect, the present invention substantially fulfills this need. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing disadvantages inherent in the known types of fire extinguishing apparatus now present in the prior art, the present invention provides a fire extinguishing tool wherein the same utilizes a planar impact surface positioned forwardly of an associated handle to address flame propagation. 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 extinguishing tool which has all the advantages of the prior art fire extinguishing apparatus and none of the disadvantages. 
     To attain this, the present invention provides a fire extinguishing tool formed as a paddle plate, including top and bottom planar surfaces coextensive relative to one another, with a handle mounted medially and longitudinally aligned relative to the plate to provide a grasping surface for an individual to impact a fire extinguishing associated flames by smothering such flames preventing oxygen access to the flame area. A modification of the invention includes a central conduit directed through the plate, with a bottom surface of the plate including a matrix of valves directed therethrough, with the handle defining a pneumatic reservoir for directing an inert gas through the bottom surface upon impacting of flames in a fire extinguishing situation. 
     My invention resides not in any one of these features per se, but rather in the particular combination of all of them herein disclosed and claimed and it is distinguished from the prior art in this particular combination of all of its structures for the functions specified. 
     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.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 9 thereof, a new and improved fire extinguishing apparatus embodying the principles and concepts of the present invention and generally designated by the reference numerals 10 and 10a will be described. 
     More specifically, the fire extinguishing tool 10 of the instant invention essentially comprises a paddle plate 11 formed of a rigid construction, including a plate rear edge spaced from a plate forward edge, with plate side edges defining top and bottom coextensive surfaces of the paddle plate 11. The rear edge 12 fixedly mounts a support handle 15, wherein the support handle is longitudinally aligned with the plate 11 and substantially medially of the rear edge 12 substantially parallel to the side edges 14. 
     FIG. 4 illustrates the plate 11 receiving a fire retardant fabric sheath 16, utilizing such commercially available fabric such as Nomex (R). A sheath entrance opening 17 permits access of the plate 11 therewithin, wherein the sheath 16 defines a cavity complementary to the geometric configuration of the paddle plate 11. A sheath wall split 18 substantially orthogonally oriented relative to the sheath entrance 17 includes a drawstring 19 directed in a serpentine relationship about the split 18 permitting securement of the split and associated sheath about the paddle plate 11. 
     The modified aspect of the invention, as illustrated in FIGS. 5-9 set forth as a fire extinguishing tool 10a, includes a paddle plate top planar surface 20 spaced from a paddle plate bottom planar surface 21. A tubular handle 22 is mounted fixedly and extending rearwardly of the rear edge 12, in a manner as set forth in the description of FIG. 1. The tubular handle 22 includes a pneumatic chamber 23 therewithin, with a fill valve 24 extending rearwardly of a rear end of the handle 22 to permit refilling of the pneumatic chamber 23 with inert gas utilized in fire fighting, such as Halon gas and the like. Plural rows of venting conduits 25 orthogonally project through the bottom surface 21. A central pneumatic conduit 26 is in pneumatic communication with the pneumatic chamber, with each of a plurality of secondary conduits 27 in communication with the conduit 26 and an associated venting conduit 25 through one of a plurality of valve members, each of the valve members including a spherical check ball 28. Each spherical check ball 28 is disposed at an intersection of a secondary conduit 27 and a venting conduit 25, wherein the spherical check ball 28 is normally biased in contiguous communication with an interior end of the venting conduit 25 by a check ball spring 29. Impact with a surface directs the ball rearwardly within a cavity defined at an intersection of the conduit 25 and the secondary conduit 27 to permit projection of the inert gas exteriorly of the venting conduit 25 and onto an associated fire to be extinguished. 
     A modified handle structure 22a is illustrated in FIGS. 8 and 9, wherein a slide member 31 is mounted for reciprocation within a slot 30 formed within the handle 22a. The slide member 31 includes a slide member leg 32 fixedly mounted to the slide member 31 at a forward end of the leg, with a rear end of the leg fixedly mounted to a valve block 33. Reciprocation of the slide member 31 accordingly effects reciprocation of the valve block 33 within the pneumatic chamber 23. The valve block 33 is biased to a rearward or first position by a return spring 39. Manual displacement of the valve block to a forward position, or second position, as illustrated in FIG. 9, displaces a plurality of annular &#34;O&#34; ring seals 35 that are positioned on opposed sides of a nozzle conduit entrance 38 of a nozzle conduit 37. The &#34;O&#34; ring seals 35 are spaced apart a predetermined width to define a gap 36, wherein each nozzle conduit entrance 38 is equal to a spacing substantially equal to or less than the predetermined width to normally prevent access of the inert gas through the nozzle conduits 37. The nozzle conduits are directed rearwardly towards the rear terminal end of the handle 23a to selectively project inert gas onto an individual&#39;s hand to thereby extinguish a flame directed about the individual&#39;s hand and further effect a cooling of the hand due to the loss of the inert gas projected from the nozzle conduits 37. A valve block bore 34 coaxially directed through the valve block 33 coextensively therethrough permits directing of the inert gas through the valve block into the associated central conduit 26, in a manner as described above. 
     It should be further noted that a slide member seal 30a mounted within the slot 30 effects sealing closure of an inert gas within the pneumatic chamber during reciprocation and positioning of the slide member relative to the slot 30. 
     As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
