DOGGING SECURITY INDICATOR FOR EXIT DEVICE

摘要

An exit device having a dogging mechanism assembly for providing a visual indication of the state or position of at least certain components of the exit device, such as, for example, a latch, drive rod, and/or a hook bracket. The dogging mechanism assembly includes a displaceable arm actuator mechanism that is coupled to the hook bracket, the hook bracket being adapted to lockingly engage the drive rod. The actuator arm mechanism is adapted to displace an indicator mechanism at least from a first indicator position to a second indicator position as the actuator arm mechanism is displaced to at least one of a first position and a second position. The indicator mechanism has one or more indicators that provide a visual indication of a state or position of a component of the exit device when the indicator mechanism is in at least one of a first and second indicator position.

主权项

1. An apparatus for selectively restraining the axial displacement of a drive rod to retain a positon of a latch of an exit device, the apparatus comprising:
an arm actuator mechanism; a hook bracket structured to be coupled to the arm actuator mechanism and to selectively lockingly engage the drive rod to prevent axial displacement of the drive rod; and an indicator mechanism structured for engagement by the arm actuator mechanism, the engagement between the indicator mechanism and the arm actuator mechanism structured to displace the indicator mechanism from a first indicator position to a second indicator position as the arm actuator mechanism is displaced from a first position to a second position, the indicator mechanism having one or more indicators that indicate a state of the drive rod when the indicator mechanism is in at least one of the first and second indicator positions.
