Electronically operated lock cylinder
An electronic lock cylinder that may be a direct replacement for a European-style standard cylinder is disclosed. The lock cylinder may include a core, a first shaft rotatably mounted in the core, and a second shaft rotatably mounted in the core and coaxial with the first shaft. A first cam and a second cam may be each rotatably mounted in the core and coaxial with the first shaft. The first cam may include a first lug and the second cam may include a second lug, where the first lug and the second lug may each be coupled to a deadbolt. A clutch may be disposed on the first shaft and shiftable from a first position to a second position, and a motor may be disposed in the core and operatively coupled to the clutch and configured to shift the clutch from the first position to the second position. When the clutch is in the first position, the first shaft is operatively coupled to the first cam, and the second shaft is decoupled from both the first cam and the second cam, when the clutch is in the second position, both the first shaft and the second shaft are operatively coupled to the second cam.
1. An assembly for an electronically operated lock cylinder, comprising:
a core having a proximal side and a distal side and a proximal cam, the proximal cam configured to operatively couple to a deadbolt;
an access housing operatively coupled to the core on the proximal side and including an access knob and an input for receiving an electronic credential;
a control housing operatively coupled to the core on the distal side and including a control knob and at least one battery receptacle;
an actuator;
the core including a channel and wiring disposed in the channel, the wiring configured at least in part to transmit power from the battery receptacle to the access housing;
wherein, upon receipt of a predetermined credential by the input, the actuator configured to operatively couple the access knob to the proximal cam.
2. The assembly of claim 1 , the input is one or more wireless antennas.
3. The assembly of claim 2 , wherein the one or more wireless antennas includes at least one of an RFID, Bluetooth, BLE, NFC, or Mobile ID antenna.
4. The assembly of claim 1 , the input including a biometric sensor.
5. The assembly of claim 1 , the input including a keypad.
6. The assembly of claim 1 , further comprising an antenna configured to operatively couple the assembly to the internet.
7. The assembly of claim 1 , further comprising at least one battery disposed in the battery receptacle.
8. The assembly of claim 1 , the core including a first shaft coupled to the control knob and a second shaft coupled to the access knob, wherein upon receipt of a predetermined credential by the input, the actuator configured to operatively couple the first shaft to the second shaft.
9. The assembly of claim 8 , a clutch disposed on the first shaft and shiftable from a first position to a second position, wherein in the second position the clutch operatively couples the first shaft to the second shaft.
10. The assembly of claim 9 , further comprising a distal cam, the clutch further including a clutch spline, wherein when the clutch in in the first position, the clutch is operatively coupled to the distal cam, wherein when the clutch is in the second position, the clutch is operatively coupled to the proximal cam.
11. The assembly of claim 10 , further comprising a slider operatively connected to the actuator, the slider being operatively coupled to the clutch.
12. The assembly of claim 11 , the slider including a finger, the finger being disposed within a recess in the clutch.
13. The assembly of claim 1 , the actuator comprising an electric motor.
