Definitions

  • This invention relates to electromechanical locks, a method of actuating such a lock on a system for such lock actuation. More particularly, the invention is concerned with a battery-powered lock where different access codes can be applied and where the system changes according to the level of the battery voltage.
  • the present invention is directed to providing an improved system for indicating a low-battery voltage.
  • This invention is directed to providing an improved system of operation wherein an incorrect access code is used.
  • This invention has as an object the provision of a new and improved battery-powered electromechanical lock method and system for signaling the condition of a low battery voltage, and further for introducing a penalty sequence wherein an incorrect access code more than a predetermined number of times.
  • an electromechanical lock with a circuit is responsive to a lock actuation signal to actuate a locking mechanism mechanically between an open and closed position.
  • a microprocessor coupled to the driver circuit to respond to access codes keyed into the lock. If an incorrect access code is keyed in more than a predetermined number of times, preferably five, a penalty sequence is applied. Such sequence would be the activation of indication means, for instance the flashing of an LED, for a predetermined time period. After that, if an invalid access code is keyed in, a second penalty sequence is applied. Such penalty sequence can be applied after the invalid code is attempted more than a predetermined number of times. The penalty sequence can also be the indication of LED flashing for a predetermined period of time.
  • a further aspect of the invention includes signaling low battery voltage. This is preferably effected when a correct access code is entered and preferably after activating the locking mechanism.
  • the low battery signal is activated in this situation each time the lock is activated.
  • Such signal is preferably an LED, which emits multiple flashes for a predetermined period of time.
  • FIGs 1 and 2 there is shown a representation of a battery-powered electromechanical lock 10 where the lock can be accessed under low battery conditions in accordance with the algorithmic sequence described.
  • the battery-powered electromechanical lock 10 comprises a housing 12 which is mounted on one side of a door 14.
  • An electronic logic circuit 20 powered by a battery 24 is mounted within the housing 12. It is responsive to a coded input sequence entered via a keypad 22 mounted to the housing 12.
  • the logic circuit 2- causes a solenoid plunger or latch 16 mounted within the door 14 to move between a closed and open position when a coded input sequence is received via a user entering the correct combination from the keypad 22.
  • the door 14 can be opened if the plunger 16 is retracted into the open position.
  • the plunger 16 is actuated to its open position, the plunger 16 remains retracted for a sufficient period of time to permit the user to open the door 14.
  • Locking of the door 14 can be effected, for instance when the user re-enters the correct access code to enable the door 14 to once again be locked in the closed position.
  • the lock 10 when under low voltage conditions, needs to be replaced.
  • the lock 10 includes a voltage or power-detection circuit 26 which is coupled between the logic circuit 20 and the battery 24. The circuit generates a low battery voltage signal whenever the current output from the battery 24 falls below a predetermined level.
  • the logic circuit 20 responds to the low voltage signal and causes a light-emitting diode 28 mounted on the keypad 22 in the housing 12 to be illuminated to give a visual indication that the battery 24 is low.
  • the system for indicating when the battery is low is illustrated in Figure 5.
  • the lock is activated as indicated by block 62.
  • the battery low signal is indicated in a sequence block 64 and the LED 28 would flash multiple times for a predetermined period, for instance five seconds as indicated by block 66.
  • This technique of indicating the low battery condition is particularly effective since it will be apparent to the user each time the door is opened, because the user is at the lock wherein the signaling is effected. Such signaling will continue until the low battery condition is changed, either by replacement of the battery or by application of an alternative battery source.
  • the logic circuit 20 comprises a microprocessor 30 having a read-only memory unit 32 and a random-access memory 34.
  • the memory 32 has at least one combination or authorized access code stored therein to be retrieved for comparison purposes with another access code entered by the user via the keypad 22.
  • the RAM would store these multiple correct access codes so that multiple different users can use this code.
  • the RAM 34 is coupled between the microprocessor 30 and an external interface unit 36 via a common database 38.
  • the interface 36 can be accessed for downloading the access variation program 100 into the RAM 34.
  • the microprocessor 30 controls the operation of the plunger 16.
  • the lock 10 also includes a transistor-type solenoid driver circuit 40 coupled between the microprocessor 30 and solenoid 42.
  • the solenoid 42 causes the plunger to move between open and closed positions when the microprocessor 30 sends an actuation signal to the driver 40.
  • the operation of the solenoid driver 40 and solenoid 42 are well known to those skilled in the art.
  • the driver 40 can be different from the solenoid driver, for instance a motor driver may be employed.
  • the code indicator entry 44 is the light-emitting diode 28 mounted on the keypad 22.
  • the lock 10 is shipped with a user code length which is factory sent and is either four or six digits.
  • the code length is not changeable.
  • the preferred lock has the LED 28 and has no audible signal means. There are preferably two codes.
  • the lock could be shipped in a preset form with user codes set as 1-1-1-1 (-1-1) and 5-5-5-5(-5-5). This is represented in Figure 3 by block 70.
  • the user enters zero four times, as indicated by block 72. This switches the LED on, as indicated by block 72.
  • the user enters the old code 76. If the old code is invalid 78, the LED is turned off 80 and the system would return to permit the user to enter the zero four times again to repeat the process.
  • the LED is on 84. The user then enters the new code twice 84 and the LED interrupts each keystroke to go off/on for each keypad entry 86. After the code length is entered effectively, the LED will be in the on or off position according to the code entered by the user.
  • the LED is off in the normal state 122. If an invalid code is entered 124, the system will be operable and the LED will be off. Alternatively, if the code is invalid 126, there is an opportunity to re-enter the code 128. If a subsequent invalid code 130 is entered, this cycles back and the opportunity is given to re-enter the code up to five times. After attempting to enter the code five times, if the input is invalid five times 132, a penalty sequence 134 applies. This causes the LED to flash every two seconds for five minutes 136. Thereafter, the code entry is permitted. Should the entry be invalid twice 138, a penalty sequence is applied again 140. The penalty sequence is the flashing of the LED every two seconds for five minutes 142.
  • This system provides for an effective use of a penalty after attempting to enter invalid codes. It is effective for signaling the user of the invalidity of the codes.
  • the lock system of the present invention provides for effective use.
  • the lock can be applied on safes or in other situations between a door and a door jamb as required.
  • the invention has been described with regard to a preferred embodiment. Many variations and modifications are possible.
