Abstract
Abstract A combined flashlight, smoke detector and emergency alarm assembly. A housing contains a flashlight having a bulb, reflector and window at one housing surface for illuminating an area adjacent to the assembly. A smoke detector is enclosed by said housing and includes an alarm for indicating the presence of smoke. A relay automatically turns the flashlight on when the alarm is activated. Vents in the housing permit ingress of smoke to the detector. A battery assembly in the housing provides power for the flashlight, smoke detector and alarm. A manually operable, momentary, normally closed, switch is provide to permit the alarm to be disabled, with the alarm enabled if this switch is released. Another switch is provided to enable the alarm independent of the smoke detector system as an emergency alarm. A manual flashlight switch is further provided to permit the flashlight to be used in a normal manner in a non-alarm situation. The battery assembly includes plural battery cells providing a higher voltage to the smoke alarm and having a tap to provide a relatively lower voltage to the flashlight.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
200 words
A combination flashlight, smoke detector and emergency alarm assembly which comprises: a housing; illumination means at one surface of said housing comprising a flashlight bulb and reflector means for illuminating an area adjacent to said assembly; a smoke detection system in said housing for detecting the presence of products of combustion; an audible alarm means in said housing; a battery means in said housing for powering said smoke detection system, alarm and flashlight bulb; automatic switch means for turning said alarm on when the level of combustion products at said detection system exceeds a predetermined threshold; a relay energized by said automatic switch means to automatically turn said flashlight bulb on when said automatic switch means is activated; handle means extending from said housing for use in carrying said combination; and a manually engagable, momentary, normally closed, switch on said handle, said manually engagable switch in series with said automatic switch means to disable said alarm while said switch is manually engaged; whereby a person in a fire situation will be alerted by said alarm and can hold said momentary switch open to turn the alarm off during escape, with the alarm automatically reactivated should said momentary switch be released.
Claim 2
Dependent Claim
200 words
A combination flashlight, smoke detector and emergency alarm assembly which comprises: a housing; illumination means at one surface of said housing comprising a flashlight bulb and reflector means for illuminating an area adjacent to said assembly; a smoke detection system in said housing for detecting the presence of products of combustion; an audible alarm means in said housing; a battery means in said housing for powering said smoke detection system, alarm and flashlight bulb; automatic switch means for turning said alarm on when the level of combustion products at said detection system exceeds a predetermined threshold; a relay energized by said automatic switch means to automatically turn said flashlight bulb on when said automatic switch means is activated; handle means extending from said housing for use in carrying said combination; and a manually engagable, momentary, normally closed, switch on said handle, said manually engagable switch in series with said automatic switch means to disable said alarm while said switch is manually engaged; whereby a person in a fire situation will be alerted by said alarm and can hold said momentary switch open to turn the alarm off during escape, with the alarm automatically reactivated should said momentary switch be released.
