Abstract
An exit device assembly is provided in which the exterior trim can be locked and unlocked from an interior lock cylinder assembly on the interior side of the door and from an exterior lock cylinder assembly on an exterior side of the door. The interior lock cylinder assembly is located on a center case of the pushbar assembly, and the exterior lock cylinder assembly is located on the exterior trim. The interior lock cylinder assembly is operable to transition the exterior trim between a locked state and an unlocked state, and the exterior lock cylinder assembly is operable to lock and unlock the exterior trim.
Claims20
An exit device assembly for mounting to an ingress side and an egress side of a door, the exit device assembly comprising:
- a pushbar assembly configured for mounting to the egress side of the door, the pushbar assembly including a pushbar for movement between a projected position and a depressed position and a latch control assembly operably connected with the pushbar and a latch mechanism such that the movement of the pushbar from the projected position to the depressed position moves the latch control assembly from a deactuated state to an actuated state that actuates the latch mechanism;
- an exterior trim configured for mounting to the ingress side of the door, the exterior trim including a manual actuator that is operably connected to one of the latch control assembly and the latch mechanism actuate the latch mechanism from the deactuated state to the actuated state;
- an exterior lock cylinder assembly mounted on the exterior trim, the exterior lock cylinder assembly being configured to rotate between a first position in which the manual actuator is prevented from being operated to actuate the latch mechanism and a second position in which the exterior lock cylinder assembly enables manual actuator to be operated to actuate the latch mechanism;
- an interior lock cylinder assembly mounted on the pushbar assembly, the interior lock cylinder assembly being configured to rotate between a first position in which the manual actuator is prevented from being operated to actuate the latch mechanism and a second position in which the interior lock cylinder assembly enables the manual actuator to be operated to actuate the latch mechanism;
- a locking arm mounted in the exterior trim that is movable by operation of each of the interior lock cylinder assembly and the exterior lock cylinder assembly;
- and
- a pivot arm in the exterior trim that is connected to the locking arm, wherein the locking arm is biased to a locked position in which the manual actuator is prevented from being operated to actuate the latch mechanism;
- wherein the exterior lock cylinder assembly acts on the locking arm to pivot the locking arm between the locked and position and an unlocked position, and the interior lock cylinder assembly acts on the pivot arm to pivot the locking arm between the locked position and the unlocked position.

- an exterior lock cylinder assembly mounted on the exterior trim, the exterior lock cylinder assembly being configured to rotate between a first position in which the manual actuator is prevented from being operated to actuate the latch mechanism and a second position in which the exterior lock cylinder assembly enables manual actuator to be operated to actuate the latch mechanism;
- an interior lock cylinder assembly mounted on the pushbar assembly, the interior lock cylinder assembly being configured to rotate between a first position in which the manual actuator is prevented from being operated to actuate the latch mechanism and a second position in which the interior lock cylinder assembly enables the manual actuator to be operated to actuate the latch mechanism;
- a locking arm pivotally mounted in the exterior trim, wherein the locking arm is pivotal by operation of each of the interior lock cylinder assembly and the exterior lock cylinder assembly from a locked position in which the locking arm is positioned to prevent the manual actuator from being operated to actuate the latch mechanism and an unlocked position in which the manual actuator is enabled to be operated to actuate the latch mechanism;
- and
- a pivot arm connected to the locking arm and pivotally coupled to the exterior trim, wherein the exterior lock cylinder assembly acts on the locking arm to pivot the locking arm between the locked and unlocked positions, and the interior lock cylinder assembly acts on the pivot arm to pivot the locking arm between the locked and unlocked positions, wherein:
- the pivot arm extends between a first end and an opposite second end;
- the first end is connected to the locking arm;
- and
- the second end is connected to a spring biasing mechanism that biases the locking arm to the locked position.
