\IIIIIIJ I w H mm mum W J ALARM SYSTEM FOR SIGNALLING FOR EMERGENCY HELP The present invention is related to signallingdevices and more particularly is concerned with a system for signalling to neighbors, passerbys, and other observers that the person using it is in need of urgent help because of serious illness or danger from intruders.

BACKGROUND OF THE INVENTION It has been reported that nearly million people in the United States are living alone and comprise senior citizens, young adults, and those inflicted with organic diseases, such as diabetes, heart trouble, periodic convulsions, and similar anomalies whereby whenseizure is imminent they need immediate physical help. Some States and cities in California have already established ,programs through the local police departments to periodically call persons registeredv with them, such as persons having permanent illnesses and senior citizens who live alone and do not have relatives or close friends to periodically visit or telephone to them to ascertain their physical conditions. g

The usual procedure in this case is for a. rnember'of the police force to call the registered person on the telephone at a predetermined time every morning. If no reply is forthcoming, a messenger with first aidkit is sent to the dwelling of the registered person to investigate and to administer first aid if necessary; or, even to break into the residence if no answer is forthcoming.

emergency switch which can be-taken into bed at night or during illness and placed at an easily accessible region of the'be d, such as under the pillow. When an emergency occurs, .theperson provided with the device presses a' button onthe switch to start the intermittent blowing of the alarm device together with the flashing age and easily can be carried in the shirt pocket of the user, while the receiver is built into the alarm and light signalling unit/Both the transmitter and the receiver operate with dry batteries. The latter mechanism has the capability of operating manually and automatically;

a pushbutton switch on the transmitter serves for manual operation and a gravityoperable switch serves to automatically energize the transmitter when a person is fallen on the floor at a supine, prone, or lateral posishut-in or unfrequented person is attacked by an intruder, burgler, or other criminal he or she has no recourse to contacting the police during such an event. Even healthy people living alone, or even with other members of the dwelling, are vulnerable to such crimes, since the attacker or the intruder will not let the person to approach the telephone or any window to call for help. i v

After having thoroughly scrutinized the above-stated situations and the uncontrollable problems involved with established police programs, the present invention SUMMARY OF THE INVENTION The present invention principally comprises a portable, compact, and small-size alarm as'well as light signalling system, which can beplaced anywhere either' outside of the dwelling or on a sill of a window that faces the busiest part of the street in that locality. The invention is provided with an extended electric cord having at the terminal end thereof an easily operable tion.

To achive these attributes, an object of the invention is to provide analarm system which is compact, lightweight, small, and easily portable from one place to another, and is preferably oflow cost, since many of the prospective users of such a device usually have limited funds.

A further object of the invention is to provide a sys' tern which consists of two units with a long electric cable connecting them remotely; one of the units having a sound alarm and flashing lights with a special switch to set the alarm and the flashing light to operate synchronously at a rate from 30 to 35 times per minute, and the other unit being a timing mechanism to channel current to the alarm and light signalling unit.

A still further object of the invention is to provide in the timing mechanism a microsw itch which turns on the alarm and light signalling unit at a predetermined time after it is set. 1

Another object of the invention is to provide on the face of the alarm and light signalling unit with large letters spelling the word HELP, the letters being die-cut in the face panel backed by a transparent red plastic or glass sheet, so that when the light flashes, the letters can be seen from a considerable distance.

A still further object of the invention is to provide a switch means on the alarm and light signalling unit housing, whereby if the piercing sound of the alarm device is uncomfortable to the person using the device and having extreme case of ear trouble can turn off the sound alarm-device, which is a high dB buzzer or alarm I the sounding of the alarm.

Another object of the invention is to provide in the system a microwave transmitter and receiver combination, the receiver serving to close a normally open switch to the remotely located alarm and light flashing unit upon energization of the transmitter either manually or automatically and broadcasting an aerial signal I structures within the housing thereof.

from any room of the dwelling to the receiver located in the alarm and light signalling unit.

Other objects and advantages of the invention will become apparent from the specification taken in conjunction with the accompanying drawing, wherein:

FIG. 1 represents the entire system comprising the sound alarm, flashing signal light, the timing mechanism, the emergency switch and the connecting cables. I

FIG. 6 is an isolated view of the receiver solenoid relay which closes the auditory alarm and light mechanisms.

FIG. 7 is the perspective view of the microwave transmitter.

FIG. 8 is a cross-sectional view of the panel shown in FIG. 3.

Referring to the drawing, the system comprises a portable alarm and light signalling unit 1 having a housing 2, which is preferably made of plastic or metal, a front panel 3 made of sheet metal or sheet plastic having the letters HELP die-cut therein and backed by a transparent sheet of plastic or glass 4 of preferably red color. An electric alarm device 5, such as a high dB (about 80 to 90) buzzer or siren, is disposed on the housing 2 at a section that offers maximum audibility at a distance of 100 to I25 feet. An on-off switch 6 is connected in series with the alarm device 5 to electrically disconnect the alarm device 5 from the system, when desired, leaving only the light bulbs 7 and 8 to flash repeatedly at a rate of about 30 to 35 flashes per minute and to illuminate the HELP during each flash.'The switch 6 is maintained closed most of the time for the most effective operation of the system.

A timing mechanism 9, which may be similar to an electric clock mechanism, except that the timer 9 is provided with a push-on and push-off switch means 10 and an indicator light 11, which is lit when switch 10 is closed; switch 10 also serves as a main power switch and, when closed, it receives through cable 12 a l volt a-c current such as that provided in a household current outlet. When closed, switch 10 provides current to the auditory alarm device 5, electric lamps 7 and 8, through cable 13 and fuse plug 14 plugged in a socket 15 located at the base section 16 of the housing 2. When the main pushbutton switch '10 is opened, the auditory alarm 5, lamps 7 and 8, and the emergency switch 17, which receives current channeled by switch 10 through cable 34, become deactivated.

As the electric current is led through cable 12 into the timing mechanism 9 the direct-connected timing mechanism 9 begins to operate, independently of any switch provided in the system, and when switch 10 is turned on it channels current through cable 13 to the fuse plug 14 and and its socket 15. Between the fuse plug 14 and socket 15 is a light flasher 18 (FIG. 5) of a type usually used for flashing Christmas tree lights or caution lights on the outside door of a photographic darkroom. From the fuse plug 14 and flasher 18 the current is branched off to the sound alarm device 5 and the two lamps 7 and 8. The flasher 18 causes the alarm device 5 and the lamps 7 and 8 to operate together about 30 to times per minute.

The light-and-alarm combination can also be turned on indirectly by means of the timing mechanism 9, which normally contains a built-in lever such as the one exemplified by numeral 19 of FIG. 5. This lever is usually located adjacent the core of the rotor of. the timing mechanism and is normally in a position shown by numeral 19A when the device is operating in its quiescent state. However, when the system user desires to operate the alarm 5 and the lights 7 and 8 at a predetermined time, ordinarily the next morning, he sets the timing pointer 20 on the timing mechanism 9 to the required time before going to bed so that in case he does not wake up due to an organic illness, passing out, or a stroke (even death!) the lever 19 automatically moves to position as at 19, shown in FIG. 5, when the set time has arrived. This action moves down the lever 21 of a microswitch'22, which is positioned adjacent the lever 19 (during manufacture of the timing mechanism) with its lever. 21 in abutment with lever 19 and closes the microswitch 22. Since the microswitch 22 is connected in series with cable 23 and 24 and pushbutton switch 10, the closing action of the microswitch 22 channels the current from the l l5-volt source to the I alarm device 5 and the lamps 7 and 8, energizing them to operation. The setting of the timing mechanism to actuate the light-alarm combination is accomplished with a knurled knob 25 at the back side of the timing mechanism 9, and to adjust the timing hand on the front surface of the timing mechanism 9 the knurled knob 26 is used.

A modified way of operating the light-alarm signalling system is by providing a battery-operated microwave transmitter 27, which may be carried in a shirt pocket and operated by pressing a button 28 during emergency. The button 28 is a pushbutton switch which closes the transmitter circuit from which a signal is transmitted to the receiver 29 provided with a relay solenoid coil 30, shown in FIG. 5. When the aerially transmitted signal reaches the receiver 29 the signal is amplified therein and fed to the solenoid coil 30, which becomes energized and closes the spring-biased switch 31 connected in series with the cables 23 and 24. Closure of the switch 31 results in the actuation of the alarm device 5 and the lamps 7 and 8 by a current passing through the flasher 18.

The signal transmission can be achieved from any part of the dwelling to the receiver 29, which may be located at a distance of up to I25 feet from the transmitter 27. The transmitter is also provided internally to its housing with a gravity-operated switch located in a section designated 32 by broken lines in FIG. 7. In this case, when a person 'carryingthe transmitter 27 is seized by a sudden attack of a cardiac trouble or stroke,

causing him to fall on the floor and not be able to get up, the gravity-operated switch 32 becomes closed and thereby energizes the transmitter 27, which then transmits a signal to the receiver 29 and resulting in the closure of switch 31. Numeral 35 is a telescopic antenna which may be left at a predetermined extension at all times.

Another advantage that may be attributed to the invention is to replace the emergency switch 17 by a nor;

mally open thermostatic switch which may be taken into bed at night or during illness, the same way as switch 17, so that when an unexpected disaster inflicts the person, the bodytemperature falls and thereby the -tem. This switch would be particularly suitable for situations where the person living alone is not frequented by any relatives or neighbors.

The disclosure of the invention described herein presents preferred methods of operating the invention;

however, variations thereof in the form, construction,

and application, such as for remotely operating electrical machines or mechanisms, can be made without departing from the spirit and scope of the appended claims.
