Abstract
An apparatus provided for releasing the dogging function of a panic device for an exit door without the use of a key or other external device includes an end cap button; an adjustable connecting rod assembly; and a modified latch plate; Depressing the end cap button pushes the rod assembly to rotate the modified latch plate to release the dogging function of the panic device.
Claims8
A dogging release mechanism for a panic device in an exit door, the panic device having an elongated housing, a door latch mechanism for operating a door latch at one end of the elongated housing, a panic bar configured to operate the door latch mechanism and a dogging mechanism for holding the door latch mechanism in a dogged or unlocked position, the dogging mechanism including a latch plate rotatably mounted within the housing for rotation by an external key, the latch plate having a latch for engaging the door latch mechanism to prevent operation by the panic bar, the dogging release mechanism comprising:
- an end cap configured to be mounted in an end of the panic device housing opposite the one end with the door latch;
- a button mounted within said end cap and configured to be manually depressed toward the interior of the panic device housing;
- a connecting rod assembly configured to be disposed in the housing of the panic bar device and including one end arranged to be contacted by said button when the button is depressed to thereby transmit a force from the button to push said connecting rod assembly, said connecting rod assembly further including an opposite end engageable to the latch plate so that the force transmitted from the button to push the connecting rod assembly rotates the latch plate thereby rotate the latch away from the door latch mechanism.

- a latch plate rotatably mounted within the housing for rotation by an external key, said latch plate including a latch for engaging the door latch mechanism to prevent operation by the panic bar and a lever separate from said latch;
- an end cap configured to be mounted in an end of the panic device housing opposite the one end with the door latch;
- a button mounted within said end cap and configured to be manually depressed toward the interior of the panic device housing;
- a connecting rod assembly configured to be disposed in the housing of the panic bar device and including one end arranged to be contacted by said button when the button is depressed to thereby transmit a force from the button to push said connecting rod assembly, said connecting rod assembly further including an opposite end engaged to said lever of said latch plate so that the force transmitted from the button to push the connecting rod assembly rotates the latch plate thereby rotate the latch away from the door latch mechanism.
