Abstract

An electronically controlled lock with a single throw acting as a passage lock and also as a deadbolt lock is provided by the invention. The lock is equipped with an electronic activation device on its exterior housing and a door lever on its internal housing. A user unlocks the door from outside by touching an electronic key against the electronic activation device. After the door is unlocked, the throw acts as a passage lock. The door can be locked internally by moving the door lever from a horizontal position upwardly to a vertical position.

Claims

1. An electronic lock capable of acting as a passage lock and as a deadbolt lock of a door having an external side and internal side, comprising:

an external housing for mounting on the external side of a door;

an electronic access device on the external housing;

a control circuit enclosed by the external housing and coupled to the electronic access device;

an electrically activated mechanism coupled to the control circuit;

a latch having a throw and being capable of extending the throw into at least a passage position and a locking position, the latch being engaged and disengaged by the electrically activated mechanism;

a tail piece having a first end and a second end, the tail piece being engaged to an outside lever;

an internal housing for mounting on the internal side of the door; and

an inside lever mounted on the internal housing and engaged to the first end of the tail piece,

wherein moving the inside lever from a horizontal position upwardly to at least a vertical position engages the latch to extend the throw into the locking position,

wherein activating the electronic access device disengages the outside lever when the throw is in the locking position, and

wherein the throw being in the passage position enables the electronic lock to act as a passage lock and the throw being in the locking position enables the electronic lock to act as a deadbolt lock.

2. The electronic lock of claim 1, wherein the electronic access device further including a powering circuit, the powering circuit being capable of receiving power from an external device and powering the control circuit with the power received from the external device.

3. The electronic lock of claim 1, further comprising:

a data storage unit coupled to the control circuit; and

a data retrieval connector placed on the external housing, the data retrieval connector being coupled to the data storage unit, wherein the data retrieval connector being capable of downloading information stored in the data storage unit to an external data reading device.

4. The electronic lock of claim 1, further comprising a power unit mounted on the internal housing, the power unit being coupled to the control unit.

5. The electronic lock of claim 1, further comprising an outside lever mounted on the external housing, wherein activating the electronic access device engages the outside lever to the latch.

6. The electronic lock of claim 1, further comprising a lock indicator mounted on the internal housing, the lock indicator being activated when the throw being in the unlocking position.

7. The electronic lock of claim 1, wherein the electronic access device being touch coupling reader.

8. The electronic lock of claim 1, wherein the electronic access device being a magnetic access reader.

9. The electronic lock of claim 1, wherein the electronic access device being a RFID reader.

10. The electronic lock of claim 1, further comprising an audio alarm coupled to the control circuit, wherein the audio alarm emits an audible alarm when the electronic access device is activated.

11. A method for using a single bolt of an electronic lock as a deadbolt and passage lock, the electronic lock being mounted on a door and having an internal lever, an external lever, a latch, and a throw, comprising the steps of:

receiving an activation request from an activation access device of the electronic lock;

validating the activation request;

engaging the external lever to the latch; and

moving the throw in the latch from a deadbolt lock position into a passage lock position.

12. The method of claim 11, further comprising the step of placing the throw to a deadbolt position when the internal lever is moved from a horizontal position to an upward vertical position.

13. The method of claim 11, further comprising the step of recording the activation request into a log;

14. The method of claim 11, further comprising the step of transferring information in the log to the activation access device.

15. The method of claim 11, further comprising the step of emitting an audible alarm when the throw being moved to the passage lock position.

16. The method of claim 11, further comprising the step of receiving power from an external power unit.

17. The method of claim 11, further comprising the step of activating a visual indicator to indicate the latch being in the passage lock position.

18. The method of claim 11, further comprising the steps of:

receiving an activation request from an activation access device;

starting a timer;

placing the throw to the deadbolt position when the external lever being moved from a horizontal position to an upward vertical position; and

disengaging the external lever from the latch when the timer expires.

19. A method for using a single bolt of an electronic lock as a deadbolt lock and as a passage lock, the electronic lock being mounted on a door and having an internal lever, an external lever, a latch, and a throw, comprising the steps of:

electronically disengaging the bolt while in the locking position by activating the activation access device, or alternatively,

engaging the bolt into a locking position by rotating the internal lever from a horizontal position to a vertical position.

20. An electronic lock capable of acting as a passage lock and as a deadbolt lock of a door having an external side and internal side, comprising:

means for mounting the electronic lock on the external side of a door;

means for activating the electronic lock;

means for controlling the electronic lock;

means for enabling the electronic lock to extend a bolt inside the electronic lock into at least a passage position and a locking position;

means for opening the door from outside;

means for opening the door from inside;

means for engaging the means for opening the door from outside to the means for enabling electronic lock to extend a bolt inside the electronic lock;

wherein moving the means for opening the door from inside from a horizontal position upwardly to at least a vertical position engages the means for enabling the electronic lock to extend a bolt inside the electronic lock to extend the bolt into the locking position,

wherein activating the means for activating the electronic lock engages the means for enabling the electronic lock to extend a bolt inside the electronic lock to extend the bolt into a passage position, and

wherein the bolt being in the passage position enables the electronic lock to act as a passage lock and the bolt being in the locking position enables the electronic lock to act as a deadbolt lock.

21. The electronic lock of claim 20, wherein the electronic access device further including powering means, the powering means being capable of receiving power from an external device and powering the means for controlling the electronic lock with the power received from the external device.
