In addition, the breakable front panel must be periodically removed to service or replace the fire extinguisher within the cabinet. On certain cabinets, this is accomplished by removing a closure plate mounted on the top wall of the cabinet and allowing the panel to slide downwardly from the bottom wall of the cabinet or by lifting the panel upwardly with respect to the top wall. For example, myprior US. Pat. No. 3,587,913, issued to William L. Fudge and Lloyd L. Klein, on June 28, 1971, discloses a bottom mounted closure, platewhich permits removal of a breakable front panel vertically downwardly through the bottom.

wall of a fire extinguisher cabinet. On manyoccasions, this operation results in the panel being inadvertently dropped with the possibility of. accidental breakage of the panel and possible injury to the individual servicing the fire extinguisher. Since the longitudinal'dimension of such cabinets are normally vertically oriented, removal of the panel member in a vertical direction generally requires considerable clearance inthe direction in which the panel member is removed.

SUMMARY OF THE INVENTION With these problems in mind, a cabinet for fire extinguishers is provided which is formed from an elongated, open front, rectangular box having spaced guideways extending in a direction transversely of the longitudinal dimension of the cabinet along an edge of a top and bottom wall adjacent the open front. A breakable panel member, for-closing the open front, is insertable into and removable from the guideways transversely of the longitudinal dimension of the panel member and cabinet. One sidewall limits movement of the panel member in one direction along the guideways and has an angular edge portion whichoverlies an adjacent edge of the panel member. A removable closure member, having-a material thickness dimension somewhat greater than that of the cabinet walls, extends substantially between the top and bottom walls and is disposed in a closure forming position to limit movements of the panel member along the guideways in an opposite direction. The closure member is cross-sectionally L-shaped and has one leg disposed in justaposition to the other sidewallv with the other leg thereof overlying the adjacent edge of the panel member andthe opposite ends thereof each .received within an adjacent guideway when the closure member is in the closure forming position. A lock is mounted on the one leg generally midway between the opposite ends of the closure member for insertion into an opening formed through the other sidewall adjacent the open front.

The particular arrangement of the spaced guideways, the angular edge portion on the one sidewall and the of a fire extinguisher within the cabinet. This not only permits removal of the panel member in a limited amount of space, with a minimum of difficulty, but since such cabinets are normally mounted with their longitudinal dimension vertically oriented, permits removal of the closure member substantially without fear.

that the panel member will accidentally fall to the ground. An important consideration, in cabinets of the general type here, is the cost of manufacture; and the present invention provides or improves construction I which can be economically manufactured.

DESCRIPTION OF THE PREFERRED EMBODIMENT extending along an edge of each of the top and bottom walls 15, 16 are each formed from an inwardly formed angular edge portion 19, rigidly attached to the respective top and bottom wall l5, 16 adjacent the open front of the cabinet 10, and a longitudinally extending flange member 20. Flange members 20 each have a crosssectionally L-shaped configuration including a leg portion 20a spaced inwardly of an adjacent angular edge portion 19 and leg portions 20b which are rigidly affixed to respective top and bottom walls 15, 16 by spot welding or the like. Each of the leg portions 20a extend parallel to respective edge portions 19 to form the guideways 18. As shown in the drawings, each of the top and bottom walls l5, 16 are provided with appropriate angular edge portions 21 for joining (also by spot welding or the like) the top and bottom walls 15,16 to the side walls l3, l4 and the back wall 17 so as to form 3 For the purpose of providing quick access to a fire extinguisher A during periods of emergency, there is provided an elongated, breakable, transparent panel I member 25. While such panel members 25 have heretofore been formed from a material such as glass, it will may be utilized as long as their characteristics are of a somewhat similar nature. to glass or construction of such a nature as to permit quick access to the fire extinguisher A during such periods of emergency. Panel member 25 is generally planar and slidably insertable into the guideways 18 to close the open front of the cabinet and prevent unauthorized access to 'or theft of the fire extinguisher A. Fire extinguisher cabinets of the above-described type are generally secured to a supporting wall structure with the longitudinal dimension thereof vertically oriented so as to support the fire extinguisher A in a vertically oriented position, see FIG. 1. Heretofore, fire extinguisher cabinets of the above type have been constructed so the breakable panel member 25 is either slidably removed vertically upwardly through the top wall or vertically downwardly through the bottom wall 16 for periodic servicing, inspection or replacement of the fire extinguisher A. In either case, the panel member -is removed from its position closingthe open front ofthe cabinet along itslongitudinal dimension, resulting in a requirement for substantial clearance adjacent the cabinet 10 in the direction in which the panel 25 is to be removed. In the present embodiment, the panel 25 is slidably insertable into or removable from the guideways 18 in a sideways direction transversely of the longitudinal dimension of the panel 25 and cabinetlO. Thus, substantially lesser clearance is required for removal of the breakable panel 25 from the cabinet 10 of the present invention.

"One of the side walls (side wall 13) is positioned adja- 8 cent the open front to limit movement of the panel member 25 along the guideways l8 in one direction so as to position the panel 25 to close the open front of the cabinet 10. An angular edge portion 13a is rigidly attached to the side wall.l3 adjacent the open front so as to overlie an adjacent edge of the panel 25 when the panel 25 is in engagement with the side wall 13 and closing the. open front'of the cabinet 10. The overlying be appreciated that other materials (i.e., plastics, etc.)

ual servicing the fire extinguisher. Likewise, in a bottom wall mounting, removal of the closure member from the bottom wall often results in the panel accidentally dropping out of the cabinet, again with the possibility of breakage of the panel and injury tothe individual servicing the fire extinguisher. As can .be seen from the drawings, the construction of the present cabinet 10 wherein the panel member 25 is removed from the guideways 18 in a sideways or transverse direction with respect to a vertical longitudinal dimension of the cabinetlO, permits removal of the closuremember 28 from itsclosure-forming position without the possibility that the panel member 25 may accidentally drop from the guideways 18. As can been seen, particularly in FIGS.

3-and-5, closure member 28 has an L-shaped cross section with one leg 28a thereof disposed in juxtaposition to'tlie other side wall 14 and the other leg 28b'disposed to overlie an adjacent edge of the panel member 25 when the closure member 28 is in the closure-forming position of FIGS. 3 and 5. The other side wall 14 is formed generally midway between the top and bottom walls 15, 16 with a keyhole-shaped opening 29 which is disposed. generally adjacent the open front of the cabinet 10, for a reason to be hereinafter described.

Lock means 30 is mounted on the leg 28a generally midway between opposite ends thereof for insertion into the keyhole-shaped opening 29. A rotatable latch member 31 is 'mounted on the lock 30 for rotation into a position wherein it has lockable engagement with the side wall 14 (see FIG. 4) to maintain the closure member 28 in the closure-forming position of FIGS..l-'5. In

formed angular edge portion 14a which is substantially relationship of the'angular edge portion 13a, together with the angular edge portions 19, serves as protection against the elements entering the cabinet 10 when the panel member 25 is in place as well as to protect the panel member 25 from the accidental displacement.

A removable closure member 28 extends longitudinally substantially between the top and bottom walls l5, 16. The closure member 28' is provided for limiting movements of the panel 25 along the spaced guideways 18 in an opposite direction to remove the panel 25 from the guideways 18. Heretofore, such'closure mem bers have been associated with eitherthe top or bottom wall of such cabinets and have been constructed in such-a way as to add unnecessarily to the cost of these types of cabinets. In a top wall mounting, such closure members have not only not been weatherproofed, but have required the removal of the panel member from the cabinet along its longitudinal dimension for periin alignment with the leg portions 20a of flange members 20. Flange member 14a extends parallel to and in a coincident relationship with the other'leg 28b of the closure member 28 when the closure member 28 is in its closure-forming position. The flange 14a serves to 11. This increased thickness adds substantially to the odic inspection, etc. This not only requires consider- ()5 strength of the closure member 28 and effectively makes it more difficult to deform the member 28 so as to gain unauthorized 'entry into 'the cabinet 10.

What I claim is: 1. In an improved fire extinguisher cabinet comprisa. an. elongated open front rectangular box having spaced side walls and spaced top and bottom walls;

. b. spaced guideway means, extending along an edge of each of said top and bottom 'walls adjacent the open front;
