Battery free smart lock
First Claim
1. A smart lock system comprising:
- i. an electrically operable smart lock element configured to be affixed to a door and having a locking mechanism configured for locking/unlocking the door, the smart lock element comprising;
a. an electrically powered key pad configured for the entry of a currently valid key code for opening of the locking mechanism and the door;
b. an externally manually operatively accessible mechanically operated power generator directly electrically connected to the smart lock element for solely providing operating energy, for powering the smart lock element, without any other power source, and for powering the electrically powered key pad for operative entry of the currently valid key code for unlocking the locking mechanism; and
c. an electronic control element;
ii. a remote, separate controller element configured to be in communication with the smart lock element, via a communication connection, only when the mechanically operated power generator provides operating energy to the smart lock element, and wherein the controller element is configured to constantly receive and store updated constantly changing currently valid key code information from a location source remote from the controller element and to transmit the currently valid key code information to the smart lock element when in communication therewith;
the remote location source generating and communicating constantly changing currently valid key code information to the controller element;
iii. a communication router to which the smart lock element is electronically connected for the communication connection, when the smart lock element is provided with the operating energy;
wherein the electronic control element within the smart lock element is configured to synchronize with the controller element, only upon the providing of the operating energy and activation of the electronic control element with an activation element to receive and store the changing and currently valid updated key code information prior to any unlocking activation of the locking mechanism, and with the electronic control element configured to compare received and stored currently valid key code information corresponding to the current valid updated key code information with entered key codes via the electrically powered key pad; and
wherein the locking mechanism is configured to be unlocked thereafter by an operator of the electrically powered key pad with direct entry of a currently valid key code, separately known to the operator of the electrically powered key pad, corresponding to the currently valid key code currently stored in the electronic control element.

Abstract
A smart lock system and method having a smart lock element, a data entry interface element; a mechanically operated power generator such as a dynamo as the sole power source; and an electronic control element. A separate controller is in communication with the smart lock element, only when the dynamo provides power to the smart lock. The controller element constantly receives and store updated key code information from a remote location source. With the providing of the operating energy to the smart lock the electronic control element receives and stores updated key code information from the controller, if any, prior to any unlocking activation of the locking mechanism. The electronic control element compares stored key code information with entered key codes and the locking mechanism is unlocked thereafter with entry of a valid key code corresponding to a key code stored in the electronic control element.

4. A method of operation of a smart lock system, with remotely generated constantly changing key codes, for closing and opening a door locked with the smart lock system, by an operator of the lock, comprising the steps of:
-
a) providing a smart lock on a door, with the smart lock having an electrically powered key pad for direct entry by the operator of a currently valid key code separately known by the operator, an electronic control element, and a manually operationally accessible mechanically operated dynamo as a sole power source for the smart lock; b) providing a controller element separate and remote from the smart lock and configured to be in data transmission communication with the smart lock only upon powering of the smart lock with the dynamo, wherein the controller element is configured to receive constantly changing updated currently valid key code information from a source remote thereto and to transmit the updated currently valid key code information to the smart lock for operational storage in the electronic control element; c) configuring the mechanically operated dynamo to open communication with the controller upon initial activation of the dynamo to provide power, and prior to entry of the currently valid key code, to effect transmission of updated currently valid key code information; and d) completion of powering the smart lock with the dynamo for direct electrically powered entry of a currently valid key code corresponding to the current updated valid key code information via the electrically powered key pad; e) electrically powered comparison, by the electronic control element, of the directly entered key code by the operator with the electrically powered key pad, with a stored current key code for the validation thereof and the opening of the door.
