Definitions

  • the invention relates to a code type lock comprising a key operated bolt and an electronic device capable of storing a code and permitting or preventing the opening of said bolt depending on the coincidence or non-coincidence of another code entered through a keyboard with the previously stored code.
  • An electronic combination door lock with dead bolt sensing means is known from U.S. ⁇ A ⁇ 4,148,092.
  • Electronic circuitry for the keyboard compares an input code with a stored code and generates an enabling signal only if the input code is the same as the stored code.
  • the outer turning knob is restrained from being manually moved to retract the dead bolt when the door is in its locked condition. This restraining of the outer knob is removed by the enabling signal which requires very little energy so that the dead bolt can be manually retracted.
  • Several different codes can be stored so that different persons can have access. The code can be reprogrammed or changed by means of the keyboard.
  • the lock of the invention is intended to be used in a safe and may present the particularity whereby each time said safe is opened the stored code is erased and the user, on leaving it closed, is able to set a new code, which may be identical to or different from the previously stored one.
  • the invention provides a means of dissuading said undue manipulations which consists in blocking the lock for a certain time, for example, half an hour, when the keyboard is unduly pressed.
  • the control system requires a direct current electric power supply, for which reason the safes will have to be connected to the mains through a current rectifying system.
  • a code type lock which comprises:
  • the lock may also be provided with:
  • An emergency power supply system with a battery, which is energized in the event of a failure in the mains supply;
  • a suitably arranged system of lamps which will always show the state of the various components of the safe and, if pertinent, indicate the possibility of performing the necessary operations to open it;
  • a key which has to be inserted in the lock of the safe on commencing the service which serves as an activator thereof and has a mechanical system which -prevents its extraction when the pin of the lock is engaged.
  • the key has at its forward end duly positioned conductor rings which, with their positioning, number, mutual separation and thickness, also make it possible to obtain a high number of combinations so that only one key may be used with a given safe.
  • the present invention has developed an arrangement according to which, when the safe is closed, it is nevertheless possible to open it, in an emergency, with a special auxiliary key which shifts the entire lock unit backward, therefore releasing the anchoring systems which close its rear cover; thanks to this it is possible to attain access to the mechanisms and other mecanical and electronic systems of the safe.
  • the door can be closed with the key-operated bolt only, independently from the electronic circuit, and the green lamp will turn off after a predetermined period of time, for example, 30 seconds.
  • the yellow lamp 10-B turns on, through the switch counter 40, which means that the code has been accepted.
  • the impulses will be counted by the counter 40 which, on being connected with the yellow lamp 10-B, will make the latter turn . on and flash for a predetermined time, for example, 4 seconds, thanks to the action of the timer 44, it then being possible to enter a new code.
  • the inputs 42 and 48 serve to reset the main storage and the counter. The subsequent digits which might be pressed out on the keyboard would not be accepted.
  • the comparator 46 will emit an impulse toward the flip-flop switch 13 which, in turn, will turn on the green lamp 10A.
  • the main storage 39 will be cleared or erased through the input 48.
  • the yellow lamp 10B will turn off and the red lamp 11 will turn on, thus indicating that the current supply 54 or 25 for the system has been cut off for a predetermined period of time, for example, half an hour, thanks to the action of the timer 36.
  • the lock according to the invention is also provided with an alarm system, to signal possible undue manipulations, comprising three sensors 49: a first thermal sensor, a second movement sensor and a third sensor formed by a microswitch for the door. Inside the lock, the sensors operate through a timer 50 a logic gate 51 which actuates an electronic switch 52 to energize an alarm siren or a warning light 53.
  • the 110-220 volt alternating current mains 54 are used as the primary electric power supply for the electric circuits which have just been described. From said mains the current is passed through a transformer which converts it to 13.5 volts. From there it passes to a diode bridge where it is converted into direct current. From this point the current passes to a 5 volt direct current regulator 58 which supplies the entire electronic system, except the mechanical lock, which is actuated by the solenoid 22, and the siren 53. In the event of a failure in the mains, the system would be supplied from the battery 25, through the logic gate 57; the invention also provides an auxiliary battery charging unit.
  • a sensor 55 will activate a flashing unit 56 which makes the red lamp 11 commence flashing by action of the logic gate 37.
  • the battery will then be connected and will assume the task of supplying the electric circuits of the device.
  • a detachable handle 102 On the external end of the key there is a detachable handle 102. If anyone attempts to extract the key by force, this handle breaks off from the body of the key which remains inside the lock.
  • a reinforced stop 104 which limits the movement of the key.
  • This stop is solidly connected with the door 103,. shown in section, in said Fig. 2.
  • the body of the key is provided with an annular groove which cooperates with a cylindrical pin P, which prevents its extraction when the lock is engaged.
  • M1 designates the key microswitch; M2 the lock microswitch (open); M3 the lock microswitch (closed); and M4 the shaft R actuating microswitch.
  • MP designates the control microcomputer. This very strong shaft R, controlled by the solenoid 122, blocks the pin P in the cases where said solenoid operates.
  • an auxiliary battery is provided for the cases of main current cutoffs.
  • this is a low power battery, it cannot energize the solenoid, which cannot therefore actuate the strong shaft R; the result of this is that the pin P can be forced and the shaft can break.
  • the pin P and the manual actuator T are connected by a spring S so that the shaft cannot break on attempting to force the system.
  • Figs. 5A and 5B show, on the one hand, the lock unit assembly 201 and, on the other, the pertinent parts with which an authorized person can open the safe even if it is closed.
  • the lock unit In the normal position, the lock unit has its latch 203 inserted in the hole 205 existing in the wall 207 of the safe, whereby the latter is kept closed.
  • Figs. 6A and 6B show the rear cover of the safe, which normally prevents access to the mechanisms and mechanical systems thereof.
  • the device of the invention has been spoken of in terms which might be called generic ones. This is due to the fact that all the electronic components are well known and they are available on the market under different embodiments. The functioning of same, isolately considered, is also known by experts on the matter.
