DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION
As shown in FIG. 1, a fire fighting tool in accordance with the present invention includes a longitudinally extending tubular nozzle 20 with a plurality of relatively small holes 22 extending along the longitudinal length and around the circumference of the nozzle 20. The nozzle 20 also includes a generally bullet shaped forward portion 24 which also includes a plurality of small holes 22 so that the surface of the nozzle 20 is essentially covered with the holes 22 so that water is sprayed out of the holes for extinguishing a fire. In a preferred embodiment of the invention the nozzle 20 has a length of about 80 cm and a diameter of about 5 cm (1.5 to 2.5 inches). The nozzle 20 is made of any suitable metal or alloy in the same manner as conventional fire fighting nozzles.
A tubular member or portion 26 is connected to or extends from the nozzle 20 and is free of the small holes in the nozzle. This tubular member extends across an opening in the wall of a structure so that the nozzle extends into the structure about 5 to 10 cm. The tubular member or portion 26 also includes a mounting member 21 and a handle 25 for carrying the nozzle 20.
The tubular member 26 is connected to a conventional fire hose 30 by means of a conventional coupling 28. As shown, the line 23 indicates the interior surface of a wall.
A mounting assembly 32 includes a base 34 that rests on an opening in a wall 33 as for example a window sill and an upper 36. The upper portion 36 includes an extension 37 having a plurality of openings for adjusting the width of the base 34 to accommodate walls of different thicknesses. The base 34 is also fitted with a suitable handle 38 for carrying the assembly 32 prior to installation and after removal when a fire has been extinguished. The assembly 32 also includes a pair of rotatable clamping members 40 for engaging an inner and an outer surface of the wall 33. The rotatable clamping members rotate about pivot points 41 and include a generally flat extension 42 that engages the bottom of the upper portion 36 to limit the rotation of the clamping members 40. The clamping members 40 also include a first perpendicular portion extending downwardly from an outer end of the first extension 42 and inwardly extending portion connected to downwardly extending portion 43. The two downwardly extending portions 43 are designed to engage the inner and outer surfaces of a wall. One of the clamping members includes a brace 44 that extends between the downwardly extending portion 43 and the inwardly extending portion to add rigidity to the assembly. The other clamping member 43 includes a turn buckle 45 and pivot 46 to apply a force against the downwardly extending portion 43. Also, one of the inwardly extending portions includes a handle 47 for positioning the clamping member 40 against the wall 33.
In addition, the assembly includes a locking device 50 adapted to receive the mounting member 21 thereunder and a bar 57 for holding the member 21 in place. The locking device 50 and bar 57 are fixed to the upper portion 36 for positioning the nozzle 20 and fastening the tubular member 26 in place. A locking/release handle 59 locks or releases the locking device in a conventional manner.
A top or plane view of the mounting assembly 32 is illustrated in FIG. 3. The assembly 32 includes the locking device 50 fixed to an upper portion 36 and handle 38 for carrying the assembly 32 from place to place. The mounting assembly 37 includes a lock base 51 and pin 52 to limit movement of the upper portion 36 on the base 34. A pair of mounting brackets 53 is also provided for carrying a transparent shield (not shown in FIG. 3). A pair of spring bias pins 55 is adapted to engage holes 37 for locking the assembly in a conventional manner. Any conventional means for locking the assembly in place and to properly space the clamping members 40 may be used.
FIG. 4 shows a transparent heat protector 60 of glass or plastic such as that used on a fireman's helmet to protect the fireman's face. As illustrated the heat protector 60 includes a metal boarder 62 and a pair of brackets 63 for mounting on or being attached to the mounting bracket 53 (see FIG. 3) on the base 34. A lower portion of the heat protector 60 also includes a U-shaped opening 64 which allows a fire hose to pass through the protector 60. One or two handles 65 may be attached to the sides of the protector 60.
FIG. 6 shows the heat shield 60 in an upright position with a hose and the entire assembly fixed to an opening in a wall 33. Further details as shown in FIG. 6 have been described with respect to the FIG. 2.
FIG. 7 illustrates the mounting assembly 32 in clamping member with the clamping member 40 fixed in a spaced apart position prior to installation on a wall. As illustrated, the clamping members 40 have been partially released from a position adjacent the assembly 32 toward a perpendicular position for engaging a wall (not shown in FIG. 7).
A schematic illustration in FIG. 8 illustrates the use of the mounting assembly on a relatively thin wall before adjustment of the spacing between the two clamping members 40. While FIG. 9 shows the mounting assembly properly fixed to a wall 33.
While the invention has been described in connection with its preferred embodiments, it should be recognized that changes and modifications may be made therein without departing from the scope of the appended claims.
