Abstract
An exemplary rotation converter includes an input component, an output component, and an intermediate component engaged between the input component and the output component. The input component is rotatable from an input component home position in each of a first direction and an opposite second direction. The intermediate component is configured to move to an actuated position in response to rotation of the input component in either direction, and to rotate the output component in an actuating direction as the intermediate component moves to the actuated position.
Claims20
An exit device assembly configured for mounting to a door having an egress side, a non-egress side, and a door preparation, the exit device assembly comprising:
- a trim assembly configured for mounting to the non-egress side of the door, the trim assembly comprising a drive spindle having a drive spindle home position, wherein the drive spindle is rotatable from the drive spindle home position in each of a drive spindle first direction and a drive spindle second direction opposite the drive spindle first direction;
- a pushbar assembly configured for mounting to the egress side of the door, the pushbar assembly comprising:a latch control assembly;a drive assembly comprising a pushbar, wherein the drive assembly is configured to actuate the latch control assembly when the pushbar is depressed;
- andan actuator configured to actuate the latch control assembly when the actuator is rotated in an actuator actuating direction from an actuator home position to an actuator rotated position;
- and
- a rotation converter mounted inside the door between the egress side and the non-egress side of the door, the rotation converter engaged between the drive spindle and the actuator;
- wherein the rotation converter is configured to convert rotation of the drive spindle from the drive spindle home position in the drive spindle first direction to rotation of the actuator from the actuator home position in the actuator actuating direction;
- and
- wherein the rotation converter is configured to convert rotation of the drive spindle from the drive spindle home position in the drive spindle second direction to rotation of the actuator from the actuator home position in the actuator actuating direction.
A rotation converter for an exit device assembly, the rotation converter comprising:
- a housing;
- an output member rotatably mounted to the housing;
- a shuttle movably mounted to the housing and engaged with the output member, wherein the shuttle has a shuttle home position and a shuttle actuated position and is configured to move in a shuttle actuating direction from the shuttle home position to the shuttle actuated position, and wherein the shuttle is configured to rotate the output member in an output member actuating direction during movement of the shuttle in the shuttle actuating direction;
- and
- an input member rotatably mounted to the housing and engaged with the shuttle, wherein the input member has an input member home position and is rotatable from the input member home position in each of an input member first direction and an input member second direction opposite the input member first direction;
- wherein the input member is configured to drive the shuttle in the shuttle actuating direction during rotation of the input member from the input member home position in the input member first direction, thereby causing the shuttle to rotate the output member in the output member actuating direction;
- and
- wherein the input member is configured to drive the shuttle in the shuttle actuating direction during rotation of the input member from the input member home position in the input member second direction, thereby causing the shuttle to rotate the output member in the actuating direction.
A method of operating an exit device assembly comprising a trim assembly mounted to a non-egress side of a door, a pushbar assembly mounted to an egress side of the door, and a rotation converter mounted inside the door between the egress side and the non-egress side of the door, the rotation converter engaged
- between a drive spindle of the trim assembly and an actuator of the pushbar assembly, the method comprising:converting, by the rotation converter, rotation of the drive spindle in a drive spindle first rotational direction to rotation of the actuator in an actuator actuating direction;
- andconverting, by the rotation converter, rotation of the drive spindle in a drive spindle second rotational direction opposite the drive spindle first rotational direction to rotation of the actuator in the actuator actuating direction.
