Abstract
A combination lock can be operated manually via the manipulation of dials and by way of an electronic key. The lock includes one or more rotatable selectors each having multiple indicia disposed thereon. Rotation of the rotatable selectors to predetermined indicia places the lock in the unlocked position. The lock can further include an electronic port and an actuator. Upon receipt of a predetermined credential via the port, the actuator can place the lock in in the unlocked position. The lock further includes a knob that, when the lock is in the unlocked position, can be rotated between a first position in which the lock is in a closed position and a second position in which the lock is in an open position.
Claims29
A combination lock with electronic override configured to mount to a standard three-hole locker prep on a door, the combination lock comprising:
- a knob rotatable between a first position in which the combination lock is in a closed position and a second position in which the combination lock is in an open position;
- a plate fixed to the rotatable knob, the plate at least in part defining a slot;
- a locking slider disposed in the slot;
- a rotatable drive shaft having a recess sized to selectively receive the locking slider, wherein when the locking slider is received in the recess, the knob is operatively connected to the drive shaft and the combination lock is in an unlocked position, and when the locking slider is not received in the recess, the knob is not operatively connected to the drive shaft, and the combination lock is in a locked position;
- a circuit board including a microcontroller;
- a port in communication with the microcontroller and configured to receive a credential;
- an actuator in communication with the microcontroller, the actuator operatively coupled to the locking slider, wherein upon receipt of a predetermined credential by the microcontroller, the microcontroller is configured to instruct that actuator to translate the locking slider into the recess of the drive shaft;
- and
- one or more rotatable selectors each having multiple indicia disposed thereon, the one or more rotatable selectors operatively coupled to the locking slider;
- wherein rotation of the one or more rotatable selectors to predetermined indicium is configured to selectively place the combination lock in the locked position and the unlocked position;
- and
- wherein when the combination lock is in the unlocked position, rotation of the knob causes rotation of the drive shaft to selectively place the combination lock in the closed position and the open position.
A locker securable by a combination lock having an electronic override, the locker comprising:
- a locker door,
- a lock housing disposed on the locker door,
- a knob partially disposed within the lock housing, the knob rotatable between a first position in which the combination lock is in a closed position and a second position in which the combination lock is in an open position;
- a plate disposed within the lock housing and fixed to the knob, the plate including a slot, and a locking slider disposed within the slot;
- a drive shaft partially disposed within the lock housing and extending out a back side of the lock housing and through the locker door, the drive shaft having a recess sized to selectively receive the locking slider, wherein when the locking slider is received in the recess, the knob is operatively connected to the drive shaft and the lock housing is in an unlocked position, and when the locking slider is not received in the recess, the knob is not operatively connected to the drive shaft, and the lock housing is in a locked position;
- a circuit board disposed within the lock housing and including a microcontroller;
- an electronic port coupled to the circuit board,
- an electronically-operated actuator in electronic communication with the microcontroller, the actuator operatively coupled to the locking slider, wherein upon receipt of a predetermined credential by the microcontroller, the actuator translates the locking slider from the locked position to the unlocked position;
- and
- a rotatable selector having multiple indicia disposed thereon, the rotatable selector operatively coupled to the locking slider, wherein rotation of the rotatable selector to a predetermined indicium shifts the lock housing between the locked position and the unlocked position;
- and
- a locking mechanism disposed on a side of the locker door opposite of the lock housing, the locking mechanism including a rotatable shaft configured to receive the drive shaft;
- wherein when the combination lock is in the unlocked position, rotation of the knob is configured to cause rotation of the rotatable shaft of the locking mechanism to selectively place the combination lock in the closed position and the open position.
