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 11):
An anti-barricading turn hub assembly for use with a lockset including a movable bolt, the turn hub assembly comprising:\n a spindle that is engaged to a thumb turn of the lockset; and a turn hub releasably engaged to the spindle and the turn hub is rotatable by a key from a side of the lockset opposite the spindle, wherein, in response to the thumb turn being free to rotate, both the key and the thumb turn are operable to rotate the spindle and the turn hub 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 to allow the key to rotate the turn hub to move the bolt between the locked position and the unlocked position while the spindle remains stationary.
