Abstract:
An anti-barricading turn hub assembly is configured for use with a lockset including a bolt movable to lock and unlock a door. The anti-barricading turn hub assembly includes a spindle connected to a thumb turn on one side of the lock. The spindle is releasably engaged to a turn hub that is operable by the key from the other side of the door. Under normal operation, the spindle and turn hub rotate together to lock and unlock the bolt. In a barricading situation in which the thumb turn is held to prevent the turn hub assembly from rotating, the turn hub disengages from the spindle upon application of sufficient force through rotation of the key, and the disengaged turn hub can be rotated to unlock the bolt even if the thumb turn is held to keep the spindle from rotating.

Claim (Index 1):
An anti-barricading system for a door, the system comprising:\n a lockset configured for mounting to the door, the lockset including:\n a lockset housing configured for mounting within the door; \n at least one bolt mounted for movement relative to the lockset housing between a locked position and an unlocked position, wherein the lockset includes a thumb turn on one side of the door for moving the bolt between the locked position and the unlocked position and a keyway on the other side of the door for receiving a key for moving the bolt between the locked position and the unlocked position; \n a turn hub assembly mounted to the lockset, the turn hub assembly including:\n a spindle engaged to the thumb turn; and \n a turn hub releasably engaged to the spindle, wherein in an engaged position rotation of the thumb turn rotates the spindle and the turn hub together to move the bolt between the locked position and the unlocked position and rotation of the key rotates the turn hub and the spindle together to move the bolt between the locked position and the unlocked position, and wherein in response to the thumb turn being held from rotation the turn hub disengages from the spindle in response to rotation of the key to rotate the turn hub to move the bolt between the locked position and the unlocked position while the spindle remains stationary.
