Abstract
A locking device that can be mounted into a rotating or swinging door is disclosed. The locking device can have a deadbolt. The locking device can detect the position of the deadbolt and/or whether the door is closed. The locking device can have a camera, microphone and speaker. The locking device can send images detected by the camera and audio detected by the microphones to a remote computer.
Claims20
A system for sensing the position of a lock comprising:
- a bolt, wherein the bolt has at least a first bolt position and a second bolt position;
- a bolt motor, wherein the bolt motor is configured to move the bolt from the first bolt position to the second bolt position;
- an interference element;
- and
- a sensor comprising a first mechanical switch and a second mechanical switch;
- wherein when the interference element and the sensor are in a first orientation with respect to the bolt, one of the interference element or the sensor is attached to the bolt such that the attached interference element or sensor rotates around an axis between a first rotational position when the bolt is in the first bolt position, and a second rotational position when the bolt is in the second bolt position,
- wherein the first mechanical switch is activated by physical contact with the interference element when the attached interference element or sensor is in the first rotational position, and wherein the second mechanical switch is activated by physical contact with the interference element when the attached interference element or sensor is in the second rotational position, wherein the second mechanical switch is inactive when the attached interference element or sensor is in the first rotational position, wherein the first mechanical switch is inactive when the attached interference element or sensor is in the second rotational position, and wherein the first mechanical switch is 45° to 135° away from the second mechanical switch relative to the axis
- a processor and a motor current sensor configured to detect a motor current, wherein the system is configured that when the motor current sensor detects that the motor current exceeds a reference value, the processor signals that the bolt is positioned at an extent of travel for the bolt.

A system for sensing the position of a lock comprising:
- a bolt, wherein the bolt has at least a first bolt position and a second bolt position;
- a bolt motor, wherein the bolt motor is configured to move the bolt from the first bolt position to the second bolt position;
- a battery removably connected to the bolt motor;
- an interference element;
- an open or closed door position sensor for detecting whether a door, in which the lock is installed, is open or closed;
- and
- a sensor comprising a first mechanical switch and a second mechanical switch;
- wherein when the interference element and the sensor are in a first orientation with respect to the bolt, one of the interference element or the sensor is attached to the bolt such that the attached interference element or sensor rotates between a first rotational position when the bolt is in the first bolt position, and a second rotational position when the bolt is in the second bolt position,
- wherein the first mechanical switch is activated by physical contact with the interference element when the attached interference element or sensor is in the first rotational position, and wherein the second mechanical switch is activated by physical contact with the interference element when the attached interference element or sensor is in the second rotational position, wherein the second mechanical switch is inactive when the attached interference element or sensor is in the first rotational position, and wherein the first mechanical switch is inactive when the attached interference element or sensor is in the second rotational position.
