  • the present invention is related to electronic lock systems and, more particularly, to a door security system, the locked/unlocked state of which is controlled by a microprocessor and a driving device which can be optionally replaced.
  • an electrically controlled door lock which typically employs an access code system, for example, a key pad or a card reader for receiving an access code input by a user of the door to identify whether the input access code is valid through a recognition device, and to them output a control signal generated from a microprocessor to cause the door latch to be released for access.
  • an access code system for example, a key pad or a card reader for receiving an access code input by a user of the door to identify whether the input access code is valid through a recognition device, and to them output a control signal generated from a microprocessor to cause the door latch to be released for access.
  • the major difference between the mechanically structured door lock and the electrically controlled door lock is that the latter does not need a general key to lock /unlock the door so that it is unnecessary for a user to carry the bulky key.
  • the electrically controlled door lock still has the following disadvantages: (1) The access code system of the electrically controlled door lock can only be accessed outdoors or disposed on the wall near the door so that it is easily damaged, thereby resulting in safety and maintenance problems; (2) The user must always remember the access code of keypad-type door lock; however, in these changing times, the number of personal passwords used for a variety of electronic products increase daily. Therefore, because the user must remember so many passwords, he may easily become confused or forget the password, thereby resulting in inconvenient use.
  • the electronic lock system includes a recognition device including a microprocessor, a scanner, an input element, a display unit, a memory device, and a data-scanning comparator, wherein the scanner, the input element, the display unit, the memory device, and the data-scanning comparator are electrically connected to the microprocessor, respectively; a lock assembly having a lock operator for selectively locking/unlocking the lock system, an actuating device for driving the lock operator, a fastener for engaging with the actuating device, and a fastening controller; a controlling device having a first marker, wherein the microprocessor will generate a signal for allowing a user to change valid data stored in the memory device corresponding to the first marker after scanning the first marker; and a driving device having a second marker which is scanned by the scanner for obtaining scanned data to be compared with the corresponding valid data stored in the memory device after inserting the driving device into the actuating device, wherein if the scanned data is valid, the micro

  • the electronic lock system is convenient for the key assembly and for changing the stored key data to meet enhanced security requirements.
  • the marker attached on one side of the control device can be scanned by the bar code scanner.
  • the scanned optical signal is converted to a digital signal and then the digital signal is sent to the data-scanning comparator via the microprocessor.
  • the digital signal is compared with the corresponding valid data stored in the memory. If the digital signal is valid, the microprocessor will send out a signal to turn on the power of the input element so as to allow the user to change the valid data stored in the memory. The user can update the corresponding valid data stored in the memory device without replacing the lock system at any time.
  • the input element is a key pad and the display unit is a liquid crystal display.
  • the electronic lock system of the present invention can be applied to the door lock.
  • the system includes a recognition device including a microprocessor, a scanner, an input element, a display unit, a memory device, and a data-scanning comparator, wherein the scanner, the input element, the display unit, the memory device, and the data-scanning comparator are all electrically connected to the microprocessor, respectively; a lock assembly having a door bolt, an actuating device for driving the door bolt to reciprocate, a fastener for engaging with the actuating device, and a fastening controller for engaging/disengaging the fastener with/from the actuating device; a control key having a first marker, wherein the microprocessor will generate a signal for allowing a user to change valid data stored in the memory device corresponding to the first marker after scanning the first marker; and a driving key having a second marker which is scanned by the scanner for obtaining scanned data to be compared with the corresponding valid data stored in the memory device after inserting
  • the lock assembly further includes a sliding slot for allowing the door bolt to slide therein, and a resilient element outwardly urging against the door bolt for keeping the door bolt extending into a hole disposed on a door frame.
  • the door bolt has a plurality of continuously spacedly disposed slots at the bottom thereof and the actuating device has a plurality of toothed structures disposed along a periphery at one end thereof to be engaged with the slots of the door bolt so as to reciprocate with the door bolt when the actuating device is driven.
  • Both the control key and driving key have prior bar codes attached or etched thereon, respectively.
