Abstract

An emergency light and smoke alarm system comprises a smoke detector mounted in a housing for detecting smoke and producing an audible and visual signal in response to the detected smoke. A flashlight is mounted on a bracket provided on the housing such that a portion of the bracket physically and electrically separates the battery terminals of the flashlight at their normal interface. When the flashlight is removed from the bracket the battery terminals are pushed into contact by a spring which turns on the flashlight.

Claims

1. A portable emergency light and smoke alarm system comprising a portable housing having a mounting bracket;

a smoke detector mounted in said housing for sensing the presence of smoke;

audible alarm means mounted in said housing and operably connected to said smoke detector for sounding an audible signal upon the sensing of smoke by said smoke detector;

light means mounted in said housing and operably connected to said smoke detector for producing a visual signal upon the sensing of smoke by said smoke detector;

DC power means mounted in said housing;

circuit means connected to said smoke detector, said audible alarm means, said light means and said DC power means for activating said smoke detector, said audible alarm means and said light means by said DC power means upon the sensing of smoke by said smoke detector; and

a flashlight mounted on said bracket of said housing, said flashlight having a DC power source for activating said flashlight wherein said bracket includes means for deactivating said DC power source of said flashlight so as to maintain said flashlight in the off position when said flashlight is mounted on said bracket and wherein said DC power source is activated automatically upon removal of said flashlight from said bracket so as to activate said flashlight.

2. An emergency light and smoke alarm system according to claim 1 including an indicating light means for indicating the condition of said means for supplying electrical power.

3. An emergency light and smoke alarm system according to claim 1 wherein said means for separating said battery terminals comprises a separator plate.

4. An emergency light and smoke alarm system according to claim 1 wherein said housing is provided with a plurality of louvered openings so as to allow smoke to penetrate the housing.

5. An emergency light and smoke alarm system according to claim 1 further including a manually actuated control means for operating said lamp independent of the detection of smoke by said smoke detector.
