Abstract
A smoke detector is provided with a threaded member which is adapted to be inserted into a conventional light bulb socket whereby the smoke detector is energized by standard AC power. A battery is incorporated on the smoke detector to provide standby power in the event of AC power failure. A battery charger is also incorporated on the smoke detector and is electrically connected to the AC power source and the battery for providing constant charging for the battery during normal operation.
Description
LIGHT SOCKET ADAPTED SMOKE DETECTOR
BACKGROUND OF THE INVENTION
1. FIELD OF THE INVENTION
The present invention relates generally to safety alarm devices. More specifically, the present invention is a smoke detector designed to utilize standard AC household power during normal conditions.
The invention incorporates a nine volt battery and a charger therefor to provide a backup power source in the event of standard AC power failure.
BACKGROUND OF THE INVENTION
1. FIELD OF THE INVENTION
The present invention relates generally to safety alarm devices. More specifically, the present invention is a smoke detector designed to utilize standard AC household power during normal conditions.
The invention incorporates a nine volt battery and a charger therefor to provide a backup power source in the event of standard AC power failure.
2. DESCRIPTION OF RELATED ART
It seems that almost daily the public is made aware of deaths, injuries, and property damage caused by accidental fires. The extent of the deaths, injuries, and property damage could have been mitigated, in most instances, if a reliable early warning system had been in place. For this reason federal, state, and municipal governments are now requiring the installation of early warning devices in domestic dwellings, hotels, hospitals and many commercial establishments. The early warning device usually required is that of a smoke detector and alarm.
One type of smoke detector, of the low cost variety, is powered by a self contained battery which requires yearly replacement. Should the battery become disconnected, the smoke detector would become inoperative. U.S. Patents Numbers 4,139,846 (Conforti), 4,251,811 (Wittlinger), and 5,105,371 (Shaw et al . ) exemplify smoke detector systems powered by batteries.
Another type of smoke detector is powered by standard household AC voltage and employs a battery as a backup power source. Systems of this type require complex circuitry to periodically test the backup battery. Furthermore, these systems are relatively expensive and complicated to install. Types of these systems are disclosed in U.S. Patents Numbers 4,088,986 (Boucher), 4,138,670 (Schneider et al.), 4,290,057 (Knight), 4,380,760 (Kornblit), 4,972,181 (Fiene), 5,621,394 (Garrick et al.) and in Japanese Patent Abstracts 52075298 and 52075299.
None of the above inventions and patents, taken either singly or in combination, is seen to disclose a smoke detector powered by standard AC
household voltage having ease of installation combined with a constant backup battery recharging system as described and claimed in the instant invention.
SUI~IARY OF THE INVENTION
The present invention is a smoke detector alarm device powered, in normal operation, by standard household AC. The detector is designed to be mounted in a conventional AC light bulb socket. A nine volt battery provides standby power in the event of AC
power failure. A charger, for keeping the battery fully charged during normal operation, is incorporated in the detector circuitry.
Accordingly, it is a principal object of the invention to provide an improved smoke detector utilizing standard household AC power as a main power source.
It is another object of the invention to provide an improved smoke detector utilizing a rechargeable DC
power source as a backup to the main power source.
It is a further object of the invention to provide an improved smoke detector wherein the backup power source is recharged by the main power source during normal operation.

BRIEF DESCRIPTION OF THE DRAWINGS
Fig. 1 is a largely diagrammatic, top perspective view of a smoke detector for use with a standard light bulb socket.
Fig. 2 is a largely diagrammatic, bottom perspective view of a second embodiment of the present invention having features as otherwise shown in Fig.
1.
Similar reference characters denote corresponding features consistently throughout the attached drawings.
DETAINED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Fig. 1 of the present invention illustrates a smoke detector at 10. Smoke detector 10 comprises an elongate member 12 having one end integrally attached to a saucer-shaped member 14. A second end of member 12 is provided with screw threads 16 so that member 12 may be engaged with a standard AC light bulb socket.
Conventional smoke detection and alarm circuitry is enclosed within member 12 and is normally powered by standard AC. Saucer shaped member 14 is formed with a bottom portion 18 having plural smoke access openings 19 (see Fig. 2) therein.
A nine volt battery 20 and a battery charger 22 are attached on an inside surface of member 14. As depicted by line 24, battery charger 22 is electrically in circuit with the AC power source, via member 12, and with battery 20 so as to provide constant recharging power for battery 20 in normal operation. The recharging circuitry is conventional.
In use, the smoke detector 10 is simply screwed into a live standard AC light bulb socket. Smoke detector 10 is immediately operational and battery 20 begins to recharge if needed. If AC power is subsequently interrupted, battery 20 will function as an emergency source to power smoke detector 10 and insure uninterrupted protection. Upon restoration of AC power, detector 10 will automatically revert to normal operation.
Fig. 2 illustrates a second embodiment of the present invention which is identical to the first embodiment but with the addition of a light bulb socket at 30. The socket 30 employs a conventional circuit housed within member 14 to provide standard AC
thereto. The circuit for socket 30 may be provided with a standard switch for on/off operation. The circuit for socket 30 is separate and independent from the circuit of the smoke detector. The instant embodiment allows the retention of a light source at the point of use of the smoke detector.
It is to be understood that the present invention is not limited to the sole embodiments described above, but encompasses any and all embodiments within the scope of the following claims.
