Having been received in the groove 42, the cord 6 pushes the actuator 36 at the outer end portion 36A and the actuator 36 causes the movable terminal 34 to move against the biasing force of the spring 33, as indicated by an imaginary line in Fig. 2, thus opening the switch 26. As long as the switch 26 is in its opened state, the device 1 generates no audible alarm. When a pulling force is exerted on the cord 6 received in the groove 42, the cord 6 is detached from the groove 42 either transversely of the groove 42, i.e., transversely of the gap 46 or pulled out longitudinally of the groove 42.

If the purse or wallet containing therein the device 1 is picked from a user's pocket and brought away from the user's body, the cord 6 will be pulled and detached from the groove 42 of the main body 4. Thereupon, the actuator 36 is released from the restriction by the cord 6 and thereby allows the movable terminal 34 to move under the biasing force of the spring 33. Consequently the switch 26 is closed and the audible alarm is generated. To stop generation of the audible alarm, the cord 6 may be pressed again into the groove 42.
- the main body 4 may be provided with a slide button or the like to stop the audible alarm.
- the slide button may be slidably moved until it bears against the movable terminal 34 and the button may be further moved so as to separate the terminal 34 from the stationary terminal 35.
- the slide button can stop the audible alarm generated after the cord 6 is detached.
- the main body 4 of the device 1 is connected to user's clothes or the like by means of the flexible cord 6, the main body 4, in other words, a purse or wallet containing therein this main body 4, is substantially free from restriction by the cord 6 in a user's pocket. Additionally, the cord 6 is readily detached from the main body 4 regardless of the direction in which the main body 4 moves in the pocket. In this manner, the device 1 is very convenient to carry, as the orientation of the device 1 in the pocket is not important.
- the checker pattern 7 and the rubber pads 10 provided on the surface of the main body 4 serve to increase a frictional force between the main body 4 and the purse or wallet and facilitate the main body 4 to remain in the purse or wallet even when the purse or wallet is being picked from the pocket.
- the device 1 might disadvantageously fall off from the purse or wallet before the cord 6 is detached from the main body 4.
- the invention may be implemented in the form of the device 1 having neither the checker pattern 7 nor the rubber pads 10 on the main body 4 so far as these components are initially considered to be unnecessary for a specific embodiment. It is also possible to provide the main body 4 with a hook member or the like by means of which the main body 4 is fixed to the purse or wallet.
- Fig. 5 is a view similar to Fig. 3 showing another embodiment of the invention.
- the contact means of the switch 26 comprises the stationary terminal 35 and the movable terminal 34 in a form of a leaf spring adapted to come in contact with the stationary terminal 35 under its own elasticity.
- the cord 6 may be inserted along an arrow X between the movable terminal 34 and the stationary terminal 35 to open the switch 26. Inversely, coming out of the cord 6 from its position causes the movable terminal 34 to come in contact with the stationary terminal 35 and thereby to close the switch 26, whereupon the audible alarm is generated.
- an appropriate mechanism other than the cord receiving groove 42 may be adopted to detachably hold the cord 6 within the main body 4.
- the cord 6 may be detachably held within the main body 4 by pinching the cord 6 between the movable terminal 34 and the stationary terminal 35 as in the case of the embodiment illustrated by Fig. 5. It is also possible to provide the cord 6 with an appropriate non-conductive member by means of which the movable terminal 34 is moved.
- the alarm device can be put in a purse, a wallet or a credit card case and generates audible alarm if the purse or the like is picked from a user's pocket and brought away from the user's body. Accordingly, the device can offer a reliable antitheft effect for these purse, wallet and credit card case.
- Such an alarm device is featured in that the main body thereof is connected to user's clothes or the like by means of a flexible cord. This feature makes the device very convenient to carry, as any specific orientation of the main body within the purse or the like is not essential for the device to work and the cord is readily detached from the main body regardless of a direction in which the main body is pulled.

- Details of an alarm device according to the invention will be more fully understood from the description given hereunder in reference with the accompanying drawings.
- An alarm device 1 shown by Fig. 1 in a perspective view is substantially rectangular in a form as well as in a size of a credit card. The device 1 comprises a main body 4 having a thickness of 2 - 5 mm and a
flexible cord 6 separably engaged with the main body 4. - The main body 4 has an
upper face plate 2 and alower face plate 3, both being substantially of a same size and secured together at their four corners by means ofscrews 5. Anupper face plate 2 is preferably made of electrically non-conductive material and has a pair of transverselyopposite surfaces opposite end surfaces upper face plate 2 is partially engraved on its top surface with achecker pattern 7 and carries thereoncircular rubber pads 10. Both thechecker pattern 7 and therubber pads 10 frictionally prevent the device 1 from slipping off a purse into which the device is inserted. Thelower face plate 3 is also preferably made of electrically non-conductive material and has an outer surface similar to that of theupper face plate 2. Thelower face plate 3 haslateral surfaces end surfaces lateral surfaces end surfaces upper face plate 2. Thelateral surfaces end surfaces 9b have the same height but theend surface 9a has a relatively small height. Theend surfaces lower face plates groove 16 opening laterally of the main body 4. Alight emitting diode 17 for checking a life of a source battery and a push-button 18 are exposed on thelateral surface 8a of thelower face plate 3. - The
cord 6 is preferably made of electrically non-conductive material having aportion 6A (Fig. 2) which is extending within the main body 4 along thegroove 16 and aremaining portion 6B which is extending outward from thegroove 16. Theportion 6B is provided with ahook member 19. - Fig. 2 is a plan view of the device 1 previously shown by Fig. 1 as the
upper face plate 2 as well as the cord have been disengaged from the device 1, separately showing the main body 4 and thecord 6. - Fig. 3 is a sectional view taken along a line III-III in Fig. 2.
- Fig. 4 is a circuit diagram illustrating an
electric circuitry 21 incorporated in the main body 4 to generate audible alarm. Thelower face plate 3 has on its inner surface with arib 10 extending continuously along thelateral surfaces end surfaces rib 10 is contiguous to thesurfaces end surface 9a locating at the left hand in Fig. 2. Theelectric circuitry 21 and the other components are arranged within a recess surrounded by therib 10. Apart 10a of therib 10 extending in parallel to theend surface 9a has a cut-out 41 through which a recess communicates with the interior and exterior of the main body 4 and acord receiving groove 42 extending outside thepart 10a between thelateral surfaces lower face plate 3 has asloped surface 43 extending upward from theend surface 9a to thecord receiving groove 42. In Fig. 3, theupper face plate 2 and thecord 6 received in thegroove 42 are indicated by imaginary lines. - The
electric circuitry 21 incorporated in the main body 4 comprises anaudible alarm generator 22, aspeaker 23, asource battery 24 and an on/off switch 26 all of which are electrically connected by aconductor 27 one to another. Thecircuitry 21 further includes a batterylife check circuit 29. Thecircuit 29 comprises aswitch 31 in addition to the previously mentionedlight emitting diode 17 and push-button 18. Thecircuitry 21 is so arranged that theaudible alarm generator 22 is energized to generate the audible alarm from thespeaker 23 when theswitch 26 is closed and deenergized to stop the alarm generation when theswitch 26 is opened. Contact means for theswitch 26 comprise amovable terminal 34 normally biased by aspring 33 to close theswitch 26, astationary terminal 35 with which theterminal 34 can detachably come in contact and anactuator 36 which is ourwardly bearing against themovable terminal 34 and biased by thespring 33 outwardly of thelower face plate 3. Theactuator 36 is made of electrically non-conductive material and has anouter end portion 36A extending outward of thelower face plate 3, aninner end portion 36B extending inwardly of thelower face plate 3 and a pair ofwing portions 36C transversely extending from theactuator 36 at an intermediate portion between the outer andinner end portions outer end portion 36A extends outward beyond therib 10a so as to lie in or outside thecord receiving groove 42 and theinner end portion 36B is bearing against themovable terminal 34. The pair of thewing portions 36C can bear against the inner wall of therib 10 in the proximity of the cut-out 41 thereof so as to keep theactuator 36 inside of therib 10a. Theupper face plate 2 may be detached from the main body 4 for exchange of thebattery 24. - The
check circuit 29 is so arranged that, upon depression of thepushbutton 18 exposed through thelateral surface 8a, theswitch 31 is closed and, if thebattery 24 is still not exhausted, thediode 17 is turned on a light. Thepushbutton 18 is normally biased by aspring 51. If the invention is implemented in the form of the device which requires no check of thebattery 24, thecircuit 29 may be eliminated. - The
cord 6 is longer than the length of theend surface 9a of thelower face plate 3 and has a diameter so dimensioned that, as shown in Fig. 3, thecord 6 can be introduced along an arrow X into agap 46 between the top of thesloped surface 43 and theupper face plate 2, then pressed into thecord receiving groove 42 in which thecord 6 is closely in contact with the upper andlower face plates groove 42, thecord 6 pushes theactuator 36 at theouter end portion 36A and theactuator 36 causes themovable terminal 34 to move against the biasing force of thespring 33, as indicated by an imaginary line in Fig. 2, thus opening theswitch 26. As long as theswitch 26 is in its opened state, the device 1 generates no audible alarm. When a pulling force is exerted on thecord 6 received in thegroove 42, thecord 6 is detached from thegroove 42 either transversely of thegroove 42, i.e., transversely of thegap 46 or pulled out longitudinally of thegroove 42. - The device 1 as has been described above may be put into a purse or a wallet with the
cord 6 of which theportion 6A is detachably held in thegroove 42 and thehook 19 of thecord 6 is fastened to user's clothes or the like. If the purse or wallet containing therein the device 1 is picked from a user's pocket and brought away from the user's body, thecord 6 will be pulled and detached from thegroove 42 of the main body 4. Thereupon, theactuator 36 is released from the restriction by thecord 6 and thereby allows themovable terminal 34 to move under the biasing force of thespring 33. Consequently theswitch 26 is closed and the audible alarm is generated. To stop generation of the audible alarm, thecord 6 may be pressed again into thegroove 42. Aside thecord 6 the main body 4 may be provided with a slide button or the like to stop the audible alarm. The slide button may be slidably moved until it bears against themovable terminal 34 and the button may be further moved so as to separate the terminal 34 from thestationary terminal 35. The slide button can stop the audible alarm generated after thecord 6 is detached. - In view of a fact that the main body 4 of the device 1 is connected to user's clothes or the like by means of the
flexible cord 6, the main body 4, in other words, a purse or wallet containing therein this main body 4, is substantially free from restriction by thecord 6 in a user's pocket. Additionally, thecord 6 is readily detached from the main body 4 regardless of the direction in which the main body 4 moves in the pocket. In this manner, the device 1 is very convenient to carry, as the orientation of the device 1 in the pocket is not important. - The
checker pattern 7 and therubber pads 10 provided on the surface of the main body 4 serve to increase a frictional force between the main body 4 and the purse or wallet and facilitate the main body 4 to remain in the purse or wallet even when the purse or wallet is being picked from the pocket. - Should the main body 4 be slippery within the purse or wallet or should the
cord 6 be not readily detached from the main body 4, the device 1 might disadvantageously fall off from the purse or wallet before thecord 6 is detached from the main body 4. It should be understood that the invention may be implemented in the form of the device 1 having neither thechecker pattern 7 nor therubber pads 10 on the main body 4 so far as these components are initially considered to be unnecessary for a specific embodiment. It is also possible to provide the main body 4 with a hook member or the like by means of which the main body 4 is fixed to the purse or wallet. - Fig. 5 is a view similar to Fig. 3 showing another embodiment of the invention. In the case of this device 1, the contact means of the
switch 26 comprises thestationary terminal 35 and themovable terminal 34 in a form of a leaf spring adapted to come in contact with thestationary terminal 35 under its own elasticity. As indicated by imaginary lines, thecord 6 may be inserted along an arrow X between themovable terminal 34 and thestationary terminal 35 to open theswitch 26. Inversely, coming out of thecord 6 from its position causes themovable terminal 34 to come in contact with thestationary terminal 35 and thereby to close theswitch 26, whereupon the audible alarm is generated. - Without departing from the scope of the invention, an appropriate mechanism other than the
cord receiving groove 42 may be adopted to detachably hold thecord 6 within the main body 4. For example, thecord 6 may be detachably held within the main body 4 by pinching thecord 6 between themovable terminal 34 and thestationary terminal 35 as in the case of the embodiment illustrated by Fig. 5. It is also possible to provide thecord 6 with an appropriate non-conductive member by means of which themovable terminal 34 is moved. - The alarm device according to the invention can be put in a purse, a wallet or a credit card case and generates audible alarm if the purse or the like is picked from a user's pocket and brought away from the user's body. Accordingly, the device can offer a reliable antitheft effect for these purse, wallet and credit card case.
- Such an alarm device is featured in that the main body thereof is connected to user's clothes or the like by means of a flexible cord. This feature makes the device very convenient to carry, as any specific orientation of the main body within the purse or the like is not essential for the device to work and the cord is readily detached from the main body regardless of a direction in which the main body is pulled.
