DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 to 7 thereof, a new and improved smoke alarm apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
More specifically, the smoke alarm apparatus 10 of the instant invention essentially comprises a first housing 11 separated from a second housing 12 by intermediate electrical connector conduit 19. The invention as illustrated in the relative FIGS. 1 and 2 sets forth the use of relative alternating current directed into the first housing by an electrical power supply 20, as opposed to a battery member supply 17 contained within the second housing 12.
The invention includes a smoke sensor member 13 in cooperation with an audible alarm 14. Such a first housing 11 by a typical fire code is positioned adjacent a ceiling or the like (not shown) within a dwelling. The smoke sensor member 13 is of conventional circuitry available in the prior art of types typified in U.S. Pat. Nos. 4,833,458 and 4,525,703, both patents incorporated herein by reference as examples of conventional smoke alarm detector apparatus.
The second housing 12 is arranged to include a signal test button 15 cooperative with the audible alarm 14 for proper indication of a circuit effectiveness of the organization, with the second housing 12 including a delay button 18 cooperative through a timer and delay circuitry housing 22 (see FIGS. 5 and 6) to effect delay of the audible alarm during actuation to prevent actuation of the audible alarm or its temporary disengagement during such conditions as fireplace smoke, cooking smoke, and the like being directed into a dwelling containing the smoke alarm structure to permit clearing of such transitory smoke. In this manner, individuals may prevent undesirable alarm signals from being directed from the audible alarm 14. Further, it should be noted that a circuit indicator light 16 utilizing typical LED type light members may be utilized to provide for visual indication of circuit availability. Further, the organization is arranged to include a battery charge indicator meter 21 of a typical analog scale, such as illustrated in the FIG. 5 for example, to indicate battery strength of the battery member 17.
The modified second housing 12a, as illustrated in the FIG. 7, is arranged to include an illumination bulb 23 arranged for continuous illumination in cooperation with a fiber optic cable 24 contained within a fiber optic cable housing 25 directed from the illumination bulb downwardly along a forward face of the lower housing 12a. The fiber optic cable housing 25 is directed into a fiber optic cable first branch 26 and a fiber optic cable second branch 27 within a lower fiber optic cable housing 25a. The first branch is directed to effect illumination of the delay button 18, with the second branch 27 oriented towards the test button 15 to provide for continuous positioning illumination of the second housing and its components for use of the organization in conditions of limited available light.
Further, a bifurcated support 28 is contained within the second housing 12a positioned rearwardly of a second housing slot 34 directed through the forward wall of the housing 12a. A first rod 29 is pivotally mounted at its rear distal end within the bifurcated support 28 and is telescopingly received within a second rod 30. The second rod 30 includes a second rod cylinder 31 slidably mounted relative to the free distal end of the second rod, with the second rod cylinder 31 containing a flexible note web 32 mounted to the second rod cylinder 31. The note web 32 contains various telephone numbers wherein an individual may remove the second rod cylinder 31 and the associated web 32 to take such information to a convenient to telephone various organizations such as a fire department, police department, a hospital, and the like. During periods of non-use, the second rod 30 is directed towards the bifurcated support 28 to receive the first rod 29 within the second rod and accordingly position the first rod 29 and the second rod 30 within the second housing slot 34. During periods of need, the second rod 30 is mounted downwardly relative to the slot 34 removing the second cylinder 31. The note web 32 is typically directed in a projecting orientation relative to the forward wall of the housing 12a from the second housing slot 34 for ease of grasping of the note web 32 during periods of use.
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.
