Abstract

A smoke alarm structure includes a first housing containing a sensor and audible alarm in electrical communication with a second housing. The second housing includes a back-up battery structure cooperative with a signal test button and a delay button in association to delay actuation of the audible alarm to permit audible alarms due to various signals such as cooking smoke and the like developed temporarily by individuals within a dwelling.

Claims

1. A smoke alarm apparatus, comprising,

a first housing, the first housing including a smoke sensor member, and

an audible alarm contained within the first housing adjacent the smoke sensor member, and

a second housing, the second housing spaced from and below the first housing, with an electrical connector conduit in electrical communication between the first housing and the second housing, and the second housing including a signal test button in cooperation with the smoke sensor member to effect selective actuation of the audible alarm, and

a delay button, the second housing including a forward wall, with the delay button and the signal test button projecting through the forward wall, and

a timer and delay circuit within a timer and delay circuit housing contained within the second housing in cooperation with the delay button to effect a timed delay of the audible alarm, and

the second housing including an illumination housing bulb mounted to the second housing, with a fiber optic cable housing positioned adjacent the illumination bulb and directed along the forward wall, and a fiber optic cable, with a fiber optic cable rear distal end positioned adjacent the illumination bulb, and a fiber optic forward distal end, and a lower fiber optic cable housing mounted to the fiber optic cable housing, with the fiber optic cable forward end including a first fiber optic cable branch positioned adjacent the delay button, and a second fiber optic cable branch positioned adjacent the signal test button to provide for illumination of the signal test button and the delay button.

2. An apparatus as set forth in claim 1 with a bifurcated support contained within the second housing, and a second housing slot directed through the forward wall forwardly of the bifurcated support, and a first rod with the first rod including a first distal end pivotally mounted within the bifurcated support, and a first rod second distal end, and a second rod slidably and telescopingly receiving the first rod second distal end and the first rod therewithin, wherein the second rod includes a cylinder slidably mounted about the second rod, with the cylinder including a flexible note web mounted to the cylinder.
