- PURSE ALARM BACKGROUND OF THE INVENTION 1.
- Field of the Invention This invention relates generally to anti-theft devices and more particularly is directed'towards a portable alarm device to inhibit purse snatching.
- Another object of the present invention is to provide a low cost, efficient alarm device for use in inhibiting purse-snatching. Another object of this invention is to provide an anti-purse-snatching device of simple design and construction and one which is conveniently set and worn by the wearer but which is substantially tamper-proof and cannot be readily disabled by the thief.
- This invention features a purse alarm comprising an electronic alarm unit adapted to beplaced in and secured to a purse or handbag and a cord connected at one end to the alram unit and at the other end formed with a simple loop that is slipped on and off the wrist of the wearer without tripping the alarm, the cord forming part of the circuit for the alarm unit.
- the cord includes a jack connection which, when separated as when the purse is pulled away by a thief, closes a circuit to the alarm causing it to go off.
- the alarm unit in the bag includes a relatively inaccessable reset button which must be closed together with the reconnection of the jack connections before the alarm can be deenergized.
- FIG. 1 is a view in perspective, partially cut away showing a purse alarm made according to the invention
- FIG. 2 is a circuit diagram of the alarm unit.
- FIG. 3 is a view in perspective showing the device in use.
- the purse alarm unit is generally organized about a box or housing containing the electronic alarm components and adapted to be placed in a purse 12 carried by a wearer.
- the box 10 is secured within the purse by means of a chain 14 connected at one end to the box and the other end to a safety pin 16, preferably of the type with an enlarged head 18 such as used for infants and which is relatively difficult to open.
- the pin may be fastened to the lining of the purse to prevent a thief from readily removing the box 10 and discarding it after it is actuated.
- the flexible cords 20 and 22 contain three electrical wires which travel the full length of the cord and the plug connector 24 is provided with three prongs, one for each wire.
- the cord section 22 preferably forms into a resilient coil section 28 and terminates in a loop 30 at its free end, which loop is passed over the wrist or forearm of the wearer.
- the resilient coil section 28 offers a certain freedom of movement with the bag, permitting it to be placed on a counter, for example, allowing the wearer to use both hands without too great a restriction and also prevents the cord from drooping.
- An adjustable clip 32 is used to form the loop and to permit changes in sizes of the loop opening.
- the circuit in the cord is not continuous around the loop so that the loop can be opened or adjusted without tripping the alarm. In practice, the loop will be adjusted so that it can be slipped on and off the wrist by the wearer yet if pulled by a thief will cause the jacks to separate before coming off the wrist.
- the box 10 is quite compact and preferably about the size of a package of cigarettes. It is of relatively rugged construction being formed ofa metal stamping, molded of plastic, or the like.
- the box is closed on all sides but with one wall held in place by screws to permit access to the interior of the box to service the unit or to replace the battery.
- the screws should be sufficiently small and difficult to manipulate so as to make it practically impossible for a thief to open the box while running. Philips screws or other relatively uncommon connecting devices may thus be used to advantage.
- the box is also provided with reset switch 34 which is deeply recessed within the box opposite a relatively small opening 36.
- the switch can be actuated only by means of a small, thin instrument inserted through the opening 36 and will be effective in turning off the alarm only if the jacks 24 have been connected. This further inhibits the thief from turning off the alarm once it has been triggered.
- the circuit is generally organized about a DC operated alarm buzzer 38 connected by lead 40 to a silicon controlled rectifier (SCR) 42.
- a voltage suppression rectifier 44 and a current sustaining resistor 46 are connected in parallel across the buzzer 38.
- a battery 48 is connected in parallel to the buzzer 38 and to the SCR 42.
- a nine volt battery is employed and is connected by leads 50 and 52 to the lead 40.
- the reset switch 34 is connected in the lead 52 and is a normally closed, spring-loaded switch, the function of which will be described below.
- the cord sections 20 and 22 each includes three leads 54, 56 and 58 with the lead 54 connected to the lead 40 and to the lead 52 while the lead 56 is connected to the base of a PNP silicon transistor 60.
- a lead 62 connects the base of the transistor 60 to the cathode contact of the SCR 42 and is provided with a base supply resistor 64.
- the lead 58 connects to a lead 66 which, in turn, is connected to the gate contact of the SCR 42.
- the lead 66 is provided with a current limiting resistor 68 and also connects to the collector of the transistor 60 as well as to the collector of another PNP silicon transitor 70.
- the base of the transistor 70 is connected by lead 72 to the emitter of the transistor 60.
- the emitter of the transistor 70 is connected by lead 74 to the lead 54 and a base leakage resistor 76 is connected between the lead 72 and the lead 54.
- the circuit configuration is such that the system is always armed or on, yet its on state does not result in the drawing of any significant power from the battery 48.
- the reason for maintaining the circuit on at all times is; first, that it is necessary to keep current flowing in the flexible cord since the triggering mechanism is the breaking of the circuit, which in this instance, is a disconnection of the plug jacks 24. Secondly, if an ON-OFF switch were provided, it would be possible for the user to forget to switch the device on when the purse or handbag is in use and thus the system would offer no protection.
- the transistors 60 and 70 will remain cut off. As a result the silicon control rectifier 42 will not have any gate current and also will be cutoff. This will prevent any current from flowing through the buzzer 38.
- the connection between the base of the transistor 60 and the positive supply is broken and base current then flows to the transistor 60 through the resistor 64.
- the transistor 60 thus turns on and also turns on the transistor 70.
- Gate current then flows to the SCR 42 through the resistor 68 and the SCR is then turned on. The current thereupon flows through the alarm buzzer 38 and the alarm is sounded.
- lt is the nature of a silicon controlled rectifier, such as the SCR 42, that if the plug is reconnected and, in turn, the gate current to the SCR 42 stops flowing the SCR will continue to be in an ON state and the alarm will continue to sound. only the breaking of the connection to the battery, using the normally closed spring contact switch 34, will shut off the alarm.
- the bag-snatcher wishes to escape, he must either; (1) run with the alarm sounding in the bag he has snatched, (2) he must shut off the alarm but, as explained above, this requires an object thinner than a pencil and a two-hand operation in addition to having ajack connection available and in place, or (3) he must rip or tear the alarm box from the lining of the handbag.
- a thief will certainly be the center of attraction, particularly in an urban area and the likelihood of his capture is increased. To this extent the device becomes a deterrent.
- these operations are virtually impossible to perform while the thief is running and if he slows or stops, this again will make his capture more likely.
- the device will, therefore, serve effectively as a deterrent.

PURSE ALARM BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates generally to anti-theft devices and more particularly is directed'towards a portable alarm device to inhibit purse snatching.
2. Description of the Prior Art A large percentage of women carry a purse or handbag in which they keep money and personal effects when traveling and shopping. Since the bag or purse often contains money and other valuable items, it has become a frequent object of theft. Purse snatchers will grab the handbag and run with it to a secluded place where the bag will be searched for valuables and then discarded. Purse-snatching has reached serious proportions, particularly in urban areas, and is of particular concern because of frequent injury sustained by the victims, particularly elderly women. While various types of alarm devices have been developed heretofore, these have not been particularly suitable for inhibiting purse-snatchers because of their cost, size and efficiency and also because of the relatively complex steps that must be followed to set and wear the device.
Accordingly, it is an object of the present invention to provide a low cost, efficient alarm device for use in inhibiting purse-snatching. Another object of this invention is to provide an anti-purse-snatching device of simple design and construction and one which is conveniently set and worn by the wearer but which is substantially tamper-proof and cannot be readily disabled by the thief.
SUMMARY OF THE INVENTION This invention features a purse alarm comprising an electronic alarm unit adapted to beplaced in and secured to a purse or handbag and a cord connected at one end to the alram unit and at the other end formed with a simple loop that is slipped on and off the wrist of the wearer without tripping the alarm, the cord forming part of the circuit for the alarm unit. The cord includes a jack connection which, when separated as when the purse is pulled away by a thief, closes a circuit to the alarm causing it to go off. The alarm unit in the bag includes a relatively inaccessable reset button which must be closed together with the reconnection of the jack connections before the alarm can be deenergized.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view in perspective, partially cut away showing a purse alarm made according to the invention,
FIG. 2 is a circuit diagram of the alarm unit. and,
FIG. 3 is a view in perspective showing the device in use.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings, the purse alarm unit is generally organized about a box or housing containing the electronic alarm components and adapted to be placed in a purse 12 carried by a wearer. The box 10 is secured within the purse by means of a chain 14 connected at one end to the box and the other end to a safety pin 16, preferably of the type with an enlarged head 18 such as used for infants and which is relatively difficult to open. The pin may be fastened to the lining of the purse to prevent a thief from readily removing the box 10 and discarding it after it is actuated. Also connected to the box 10 are sections of insulated electrical cords 20 and 22 detachably connected to one another by means of a plug or jack connector 24 which, in practice, should separate under a pull of perhaps ten pounds. The flexible cords 20 and 22 contain three electrical wires which travel the full length of the cord and the plug connector 24 is provided with three prongs, one for each wire. The cord section 22 preferably forms into a resilient coil section 28 and terminates in a loop 30 at its free end, which loop is passed over the wrist or forearm of the wearer.
The resilient coil section 28 offers a certain freedom of movement with the bag, permitting it to be placed on a counter, for example, allowing the wearer to use both hands without too great a restriction and also prevents the cord from drooping. An adjustable clip 32 is used to form the loop and to permit changes in sizes of the loop opening. The circuit in the cord is not continuous around the loop so that the loop can be opened or adjusted without tripping the alarm. In practice, the loop will be adjusted so that it can be slipped on and off the wrist by the wearer yet if pulled by a thief will cause the jacks to separate before coming off the wrist.
The box 10 is quite compact and preferably about the size of a package of cigarettes. It is of relatively rugged construction being formed ofa metal stamping, molded of plastic, or the like. The box is closed on all sides but with one wall held in place by screws to permit access to the interior of the box to service the unit or to replace the battery. Preferably the screws should be sufficiently small and difficult to manipulate so as to make it practically impossible for a thief to open the box while running. Philips screws or other relatively uncommon connecting devices may thus be used to advantage. The box is also provided with reset switch 34 which is deeply recessed within the box opposite a relatively small opening 36. The switch can be actuated only by means of a small, thin instrument inserted through the opening 36 and will be effective in turning off the alarm only if the jacks 24 have been connected. This further inhibits the thief from turning off the alarm once it has been triggered.
Referring now more particularly to FIG. 2 of the drawings, a detailed description of the circuit will be given. The circuit is generally organized about a DC operated alarm buzzer 38 connected by lead 40 to a silicon controlled rectifier (SCR) 42. A voltage suppression rectifier 44 and a current sustaining resistor 46 are connected in parallel across the buzzer 38. Also, connected in parallel to the buzzer 38 and to the SCR 42 is a battery 48. Preferably a nine volt battery is employed and is connected by leads 50 and 52 to the lead 40. The reset switch 34 is connected in the lead 52 and is a normally closed, spring-loaded switch, the function of which will be described below. The cord sections 20 and 22 each includes three leads 54, 56 and 58 with the lead 54 connected to the lead 40 and to the lead 52 while the lead 56 is connected to the base of a PNP silicon transistor 60. A lead 62 connects the base of the transistor 60 to the cathode contact of the SCR 42 and is provided with a base supply resistor 64. The lead 58 connects to a lead 66 which, in turn, is connected to the gate contact of the SCR 42. The lead 66 is provided with a current limiting resistor 68 and also connects to the collector of the transistor 60 as well as to the collector of another PNP silicon transitor 70. The base of the transistor 70 is connected by lead 72 to the emitter of the transistor 60. The emitter of the transistor 70 is connected by lead 74 to the lead 54 and a base leakage resistor 76 is connected between the lead 72 and the lead 54.
The circuit configuration is such that the system is always armed or on, yet its on state does not result in the drawing of any significant power from the battery 48. The reason for maintaining the circuit on at all times is; first, that it is necessary to keep current flowing in the flexible cord since the triggering mechanism is the breaking of the circuit, which in this instance, is a disconnection of the plug jacks 24. Secondly, if an ON-OFF switch were provided, it would be possible for the user to forget to switch the device on when the purse or handbag is in use and thus the system would offer no protection.
As long as the plug 24 is connected, the transistors 60 and 70 will remain cut off. As a result the silicon control rectifier 42 will not have any gate current and also will be cutoff. This will prevent any current from flowing through the buzzer 38.
Should the plug 24 be disconnected or the flexible cord cut, the connection between the base of the transistor 60 and the positive supply is broken and base current then flows to the transistor 60 through the resistor 64. The transistor 60 thus turns on and also turns on the transistor 70. Gate current then flows to the SCR 42 through the resistor 68 and the SCR is then turned on. The current thereupon flows through the alarm buzzer 38 and the alarm is sounded.
lt is the nature of a silicon controlled rectifier, such as the SCR 42, that if the plug is reconnected and, in turn, the gate current to the SCR 42 stops flowing the SCR will continue to be in an ON state and the alarm will continue to sound. only the breaking of the connection to the battery, using the normally closed spring contact switch 34, will shut off the alarm.
Accordingly, ifthe bag-snatcher wishes to escape, he must either; (1) run with the alarm sounding in the bag he has snatched, (2) he must shut off the alarm but, as explained above, this requires an object thinner than a pencil and a two-hand operation in addition to having ajack connection available and in place, or (3) he must rip or tear the alarm box from the lining of the handbag. In the first case, a thief will certainly be the center of attraction, particularly in an urban area and the likelihood of his capture is increased. To this extent the device becomes a deterrent. In the second and third situations. these operations are virtually impossible to perform while the thief is running and if he slows or stops, this again will make his capture more likely.
In addition to the foregoing features, several other advantages are present in the system. For example, if the thief wishes to stop the alarm, once tripped, he must have both jack connectors and try to re-insert the plug connected to the alarm box. However, from the operation of the circuit described above, it will be seen that once the alarm is tripped, only the reset button 34 inside the box can be used to shut off the alarm and this is effective only if the plug has been reconnected. Should the thief try to cut the wires before snatching, the alarm will sound since the electric circuit has been broken. Should the thief try to short the circuit at some point in the cable between the plug and the alarm box by piercing the cable with a sharp metallic object, then he will short the third wire and this will trip the alarm.
thief. The device will, therefore, serve effectively as a deterrent.
While the system has been described with particular reference to the illustrated embodiment, numerous modifications thereto will appear to those skilled in the art. For example, if a woman makes a practice of keeping most of her money in a handbag, a pick-pocket could remove the wallet from the handbag without her tripping the alarm. In this case, an extra chain and pin can be attached to the device running from the flexible cord on the wrist side to the wallet. Thus, if the wallet was snatched from the handbag, the plug would be disconnected and the alarm would sound.
Also, instead of using an SCR as the triggering switch device, other circuits may be employed which draw no significant current from the battery. For example, a circuit using field effect transistors may be employed. Preferably any such circuit should utilize high impedance, semi-conductive components.
Having thus described the invention what I claim and desire to obtain by Letters Patent of the United States is:
