Abstract
Disclosed are various embodiments of lock devices, systems, and methods. A lock of the application can include an internal mechanism to permit backdriven operation and lost motion operation. In one form the lock can be made from an assembly of parts that have locating features that require one way installation/assembly. The lock can include an internal power source capable of driving electronics used to determine handedness of a door.
Claims27
A door lock apparatus comprising:
- a locking mechanism actuatable between a locked position and an unlocked position;
- an electronically controllable actuator operable to actuate the locking mechanism between the locked position and the unlocked position via at least one driving member based upon an electronic command;
- a first position sensor coupled to and moveable with the driving member;
- a manual actuator operable to actuate the locking mechanism between the locked position and the unlocked position;
- a second position sensor coupled to and moveable with the manual actuator;
- an encoder configurable in a plurality of physical states by moving the first position sensor and the second position sensor;
- and
- a controller operable to control the electronically controllable actuator and to evaluate a position of the locking mechanism for both a left hand configuration of the lock and a right hand configuration of the lock based upon input from at least one of the first position sensor and the second position sensor.
The door lock apparatus according to claim 8 wherein the deadbolt is tapered substantially along an axis of motion.
A non-transitory computer readable medium configured to store executable instructions comprising:
- lock actuation instructions executable to control an actuator to apply force to a locking mechanism of a door lock in a locking direction and an unlocking direction;
- and
- position sensing instructions executable to evaluate a state of an encoder including a plurality of circuits, the state of said circuits varying based upon the locking mechanism position;
- wherein a first set of states of the plurality of circuits designates a position of the locking mechanism for a left handed lock and a second set of states of the plurality of circuits designates a position of the locking mechanism for a right handed lock.
An electromechanical door lock comprising:
- a locking mechanism actuatable between a locked position and an unlocked position;
- a motor operable to apply force to the locking mechanism in a locking direction and an unlocking direction via at least one gear;
- a knob operable to apply force to the locking mechanism in the locking direction and the unlocking direction, the knob being in a lost motion relationship with the gear;
- an encoder configured to assume a plurality of states depending upon a position of the gear and a position of the knob, a first group of the plurality of states providing information for a left handed configuration of the door lock and a second group of the plurality of states providing information for a right handed configuration of the door lock;
- and
- a controller operable to control the motor to apply force to the locking mechanism, receive information from the encoder indicating the position of the gear and the position of the knob, and evaluate position of the locking mechanism for a left hand configuration of the door lock or a right hand configuration of the door lock.
