Abstract
ABSTRACT OF THE DISCLOSURE
A fire extinguisher cabinet protectively encloses a fire extinguisher of the portable type and provides a transparent movable access panel through which the fire extinguisher may be readily seen. Movement of the access panel and an actuating arm thereon actuates an audible alarm to indicate that the cabinet has been opened. A trigger member controlled by a key controlled lock is provided to move the actuating arm to inactive position. The cabinet discourages theft of the fire extinguisher as the same cannot be removed therefrom without opening the access panel and actuating the alarm unless the key controlled lock and actuating arm is moved to inactive position prior to moving the access panel. This invention is distinguishable from other inventions by reason of the arrangement of the access panel and its actuating arm and the trigger member of the alarm device engaged thereby.

Description
~o~709;~
Background of the Invention (1) Field of the Invention:
This invention relates to cabinets in which portable fire extinguishers may be positioned for convenient access in case of a fire.
t2) Description of the Prior Art:
Prior structures of this type have provided cabinets in which portable fire extinguishers may be positioned. See for example U.S.Patent 3,042,910 of July 3, 1962 to Frank T. Shull wherein a cabinet with a hinged door is provided with oppositely disposed pressure plates normally engaging the sides of the extinguisher therein, the arrangement is such that removal of the extinguisher actuates an alarm controlled by the pressure plates normally engaging the sides of the extinguisher therein.
The prior art includes several devices which support or otherwise hold fire extinguishers and incorporate alarm devices actuated by move~
ment of the supporting devices, for example hooks on which the fire extinguishers can be suspended. See U.S. Patent No. 3,145,375 of Aug.
18, 1964 to V.B. Webb.
The present invention provides a cabinet with a transparent drop front and built in alarm means which is actuated when the drop front is moved to perm;t the fire extinguisher to be removed from the cabinet. ;
Summary of the Invention A fire extinguisher cabinet comprises a wall mounted box of a size sufficient to enclose a portable fire extinguisher, a transparent slidable front panel normally closes the box and is held in closed position by a simple latch which upon manual actuation drops the panel and permits the fire extinguisher to be removed from the cabinet. An audible alarm device is positioned in the cabinet and normally held inoperative by a 28 trigger arm. A key controlled lock having an actuating arm for engaging and moving the trigger arm is positioned through the transparent slidable front panel. Actuation of the key controlled lock will move the actuating ,:~t .
'31LO9~7~3 arm to a second position where it will not engage the trigger arm of the alarm device. The cabinet carries warnings of the audible alarm which will sound if the cabinet is opened before the actuating arm of the loak mechanism is disengaged.
The cabinet thus substantially deters theft of the fire ext;nguisher therefrom and/or sounds the audible alarm in the event of a fire and the legitimate removal of the fire extinguisher for its indicated purpose.

Description of the Preferred Embodiment :
By referring to Figures 1 and 2 of the drawings the fire extinguisher cabinet may be seen and in Figure 1 a broken line representation of a fire extinguisher F is illustrafed positioned on a bottDm 10 of a rectangular cabinet including top and side walls 11 and 12 respectively and a back panel 13. Tha forward edges 28 of the sid~s 12 and the top 11 define inwardly turned chunnels 14. There is no "1~47(1~3 comparable channel on the forward edge of the bottom 10 of the cabinet.
transparent slidable front panel 15 is movably positionecl in the inturned channels 14 and held in a position closing the front of the fire extinguisher cabinet by a manually movable latch 16 mounted on the bottom 10 of the cabinet. A key actuated cylinder lock assembly 17 is posit;oned ;n an aperture in the upper right hand por-tion of the transparent slidable front panel 15 and arranged to move an actuat;ng arm 18 in an arc based on the axis of the cylinder lock assembly 17. :
In Fiaure 1 of the drawings the actuating arm 18 is shown in horizontal position and overly;ng one end of a trigger arm 19 which is pivoted intermediate 10 its ends by a pivot 20 to the side wall 12. The arrangement is best illustrated ;n Figures 3 and 4 of the drawlngs and by referring to F;gure 3 it will be seen that the one end of the trigger arm 19 is posit;oned ;n spaced relation below the actuatin arm 18. This relative positioning of the arms 18 and 19 is maintained as long as the transparent slidable front panel 15 ;5 in elevated pos;tion clos;ng the front of the fire extinguisher cabinet .
By referring now to Figure 2 oF the drawingsj the transparent front panel 15 is shown moved downwardly reiative to the top 11 ancJ the trigger arm 19 ;s shown after hav;ng engaged the end of the actuating arm 18 and moved lt to a second position as best seen in Figure 4 of the drawings. The trigger arm 19 normally is engaged 20 behind a pair of hori~ontally spaced members 21 which are formed on the upper end of a vertically positioned cross sectionally c`hannel shape mounting bracket 22 An elongated leaf spring 23 is affixed to the mount;ng bracket 22 and is normally held in vertical position by the trigger arm 19 as best seen in Figures 3 and 5 of the draw;ngs.
Still referring to Figures 5 and 6 of the drawings it will be seen that the ~;
bracket 22 which is mounted on the wall 12 of the extinguisher cabinet and on the ~-inside thereof normally supports a compressed gas container 24 which has an actua-28 ting valve and stem 25 in its uppermost end on which is positioned a horn 26, the , , . . ~ , ., , ~ , , ~ , .. .
1~47~93 - arrangement is such ~hat when the stem 25 is moved from its normal vertica1 position the valve therein opens and the compressed gas contents of the con-tainer 24 are discharged through the horn 26 to create a loud sound.
It will thus be seen that as a direct result of moving the latch 16 and dropping the transparent slidable front panel 15 to gain access to the fire extinguisher F, the horn 26 is actuated and an audible alarm given.
In Figures 7 and 8 of the drawings, details of the bracket 22, the spring 23 and a clamping band 27 may be seen and will be recognized as the means for holding the gas container 24 in operative Position in the bracket 22.
The bracket 22, the pressure container 24, the valve stem 25 and the horn 26 are commercially available items made by Falcon Safety ~roducts Inc. of Mountainside, New Jersey, U.S.A.and are normally actuated by a slide piece holding the spring 23 in vertical position with the slide piece being attached to a chain which in turn is attached to a window sash, a door, or ~-the like so that the alarm is sounded when the window or the door is opened.
In Figures 1 - 6 the alarm device is shown enclosed in a housing 28 ~
which may be removed to permit replacement of a recharged compressed gas ~ -container 24, etc.
It will thus be seen that a fire extinguishing cabinet has been 2û disclosed in which a portable fire extinguisher may be conveniently positioned and that it is readily available by actuating a simpie manual latch 16 and ~;permitting the transparent slidable front panel 15 of the cabinet to drop downwardly.
It will also be observed that when this occurs an audible alarm will be given; if desired an electric switch 26 (see Figures 5 and 6) can be incorporated in the audible alarm device and connected by a suitable electric circuit with an adjacent or a remote audible or visible alarm as desired.
28 Although but one embodiment of the present invention has been illus-trated and described, it will be apparent to those skilled in the art that various . ~ . .
