Definitions

  • the present invention relates to a safety means and more particularly to means to be used in conjunction with safes, strong rooms and the like. More specifically, the invention relates to a device which can be incorporated within or added to a combination lock for safes or the like which renders such combination lock pickproof.
  • a safety mechanism for safes in the form of a combination trap, which includes a mechanical part and an electronic part.
  • the mechanical part comprises a toothed or cammed wheel keyed on the safe's combination wheel shaft and a pivotably mounted lever arm, one free end of which is adapted to engage the toothed or cammed wheel.
  • the other free end of the arm is in contact with an electromagnet which in turn is part of an electronic circuit. When activated, the electromagnet attracts the lever arm. The free end thereof then engages the toothed or cammed wheel thus locking it and preventing its rotation.
  • a door safe 1 is provided with a common combination mechanism 2, operated from the outside by combination wheel 3.
  • the wheel is mounted on an axis or shaft 4.
  • the electrical part of the present invention comprises (see Fig. 4) a microswitch or sensor 11 which is connected to toothed wheel 5 and which senses the revolutions of the wheel 5 regardless of its direction and outputs pulses representative thereof.
  • the electrical pulses are counted by a microprocessor 12.
  • the microprocessor 12 activates electromagnet 10 which forms part of the locking mechanism 20. This attracts lever arm 6 and causes the end 8 to engage wheel 5 and block its rotation.
  • the microprocessor 12 releases the electromagnet 10 and consequently the combination wheel 3 is released.
  • the microprocessor 12 may calculate the predetermined period by keeping an internal count of time as, for example, by executing a sequence of instructions a predetermined number of times. Alternatively, the microprocessor 12 may determine the elapsed time by receiving inputs from a timer 22.
  • the microprocessor may maintain a software generated calendar, and alter the magnitude of the predetermined period (during which the lock is disabled) so that it is enlarged to 30 minutes or more on weekends, holidays, etc.
