Abstract
A lock system includes a first housing, a plug, and a deadlock system. The first housing including a first side defining an opening. The plug is disposed within the first housing and is configured to move within the opening between an open position and a plugged position. The deadlock system is disposed within the first side of the first housing and coupled to the plug. The deadlock system is configured to move between a first position and a second position. The deadlock system (i) inhibits movement of the plug in the first position and (ii) allows movement of the plug in the second position.
Claims23
A lock system comprising:
- a first housing including a first side defining an opening;
- a plug disposed within the first housing and configured to move within the opening between a first position and a second position;
- and
- a deadlock system disposed within the first side of the first housing and operatively coupled to the plug, the deadlock system including:
- an actuator engaging the plug and configured to move between a third position and a fourth position, and
- a biasing member coupled to the actuator and configured to move the actuator between the third position and the fourth position, wherein:
- the actuator (i) inhibits movement of the plug in the third position and (ii) allows movement of the plug in the fourth position, and
- movement of the biasing member disengages the actuator from the plug to allow movement of the plug.

- a deadlock system disposed within the first side of the first housing and including:
- an actuator engaging the plug and configured to move between a third position and a fourth position, and
- a biasing member coupled to the actuator and configured to move the actuator between the third position and the fourth position, and
- a first actuation system disposed within the first side of the first housing and configured to move between a fifth position and a sixth position,
- wherein the first actuation system (i) moves the plug from the second position to the first position when the first actuation system moves from the fifth position to the sixth position, and (ii) secures the plug in the second position when the first actuation system moves from the sixth position to the fifth position, and
- wherein movement of the biasing member disengages the actuator from the plug to allow movement of the plug.
