Definitions

  • This invention relates to a pocket burglar alarm which can be fitted to wallets, wads of bank-notes, credit cards etc. It is common knowledge that wallets and other small objects of value which are generally kept in pockets or handbags can be stolen by pick-pockets without the owner realizing what is happening.
  • the principle is based on the application to the object of a tiny card fitted with an acoustic alarm or buzzer supplied by an electric battery; this acoustic alarm is activated automatically by a switch consisting of a photoelectric cell which transmits current to the buzzer only when excited by light.
  • the same is fitted with a small mobile screen covering the above photoelectric cell when the object to which the burglar alarm card is applied, is used normally, so as to prevent the electric photocell from being constantly activated by light and consequently setting off the acoustic alarm continuously.
  • the card When, on the other hand, the card is to be activated in its function of burglar alarm - the object to which the card is applied must first be placed into a pocket or bag to which light cannot filter - and then the screen which covers the photoelectric cell is removed.
  • the photoelectric cell operated switch In the dimness, the photoelectric cell operated switch is not activated and consequently does not enable the buzzer; if however a potential robber attempts to slide the object with the card from the pocket or bag, the photoelectric cell of the card - without its covering screen - is exposed to light which excites the same and indirectly activates the buzzer.
  • the card in question is consequently not only useful as a burglar alarm but can also prevent the owner from losing the same in that when the device is applied to the object and activated, the alarm will go off even if the object is dropped accidentally from the bag or pocket, and is consequently exposed to light.
  • an elastic clip which is attached to the wallet, wad of bank-notes or credit card, is fitted on the back, that is on the opposite side to that on which the photoelectric cell is fitted; alternatively, an elastic band could be fitted on the back into which the object can be fixed, or the card in question could be fitted into a specially designed compartment made on special wallets having an opening through which the photoelectric cell of the card can be exposed to light.
  • the device in question consists of a light and thin card (1) - made possibly in plastic - on which a battery (2) is installed for supplying power to an acoustic alarm (3) connected with a switch consisting of a photoelectric cell (4) between the same; when this photoelectric cell (4) is exposed to light, the same transmits the battery (2) current to the buzzer (3) thereby setting off the acoustic alarm of the same (3).
  • the card in question (1) is also fitted with a mobile screen (5) - which may be realized either in a version revolving around a pin having an eccentric support (refer to figure 2) or in a shutter version, sliding parallel to the same - so as to cover the photoelectric cell (4) in a position in which it can totally cover the same so as to interrupt the flow of electric current from the battery (2) to the acoustic alarm (3).
  • a mobile screen (5) which may be realized either in a version revolving around a pin having an eccentric support (refer to figure 2) or in a shutter version, sliding parallel to the same - so as to cover the photoelectric cell (4) in a position in which it can totally cover the same so as to interrupt the flow of electric current from the battery (2) to the acoustic alarm (3).
  • a spring (6) is fitted on the back of this burglar alarm card (1) for fixing the device in question to the objects of value to be protected.
  • this spring (6) may be replaced by any other equivalent means of fixing, such as an elastic band.
