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.

A lock device that prevents operation of at least one chassis spindle from retracting a latch bolt, and which may provide auto-unlock features. Locking of the lock device can effectuate linear displacement of a slider body from an unlocked position to a locked position. Linear displacement of the slider body is translated into rotational displacement of a cam body that includes, or is coupled to, a locking shaft having a cam protrusion, thereby rotating the cam protrusion. As the cam protrusion rotates, the cam protrusion lifts a locking lug to a locked position wherein the locking lug prevents rotational displacement of a first chassis spindle. When in the locked position, a slider arm of the slider body can be positioned in a retention slot. Subsequent rotable displacement of a second chassis spindle can effectuate displacement of the slider arm from the retention slot and facilitate unlocking of the lock device.

A lock with an emergency unlocking feature includes a latch bolt, a top rotation member, a restriction plate and a driving member. The driving member is connected to the deadbolt. When the top rotation member is rotated from a close position to an open position while the lock is locked, a restriction member drives the restriction plate to press a resilient unit. The restriction plate is moved to disengage the engaging member on the restriction plate from the second notch of the driving member. The guide slot of the transmission plate pulls the second guide member to move the deadbolt to the unlocked position, and the latch bolt moves to the open position. When in an emergency situation, the user rotates the handle to retract both of the deadbolt and the latch bolt without using a key to unlock the deadbolt to save time.

A lockout system includes a hasp assembly and a plurality of tags. The hasp assembly has a back plate defining slots each sized and shaped to receive a tag. The back plate and tags each have openings that align when a tag is received in a slot. A first hasp portion has a first loop portion and a second hasp portion has a second loop portion. The first and second hasp portions are rotatable with respect to one another such that moving the lockout system has both an unlocked position and a locked position associated with an open position and a closed position. In the closed position, the first and second hasp portions complete and define a closed loop, where one or more tags can be installed in slots preventing further movement from the closed position.

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.

A safety lock and access key for doors that otherwise need to remain locked comprising a lock body containing a spring biased catch extending from one end of the body to engage in a keep of the door frame, a lever for moving the catch into the body to unlock the door, and a tool for unlocking locked doors.

An anti-barricading thumb turn assembly is configured for use with a lockset including a bolt movable to lock and unlock a door. The anti-barricading thumb turn assembly includes a spindle connected to a thumb turn with a biasing member on one side of the lockset. The lockset is also operable by a key from the other side of the door to lock and unlock the door. Under normal operation, the spindle and thumb turn rotate as the bolt is locked and unlocked. In a barricading situation in which the thumb turn is held in an attempt to prevent the spindle from rotating, the biasing member allows the spindle to rotate relative to the thumb turn upon application of sufficient force through rotation of the key to overcome the biasing force and unlock the bolt even if the thumb turn is held stationary.

A lock for a door including a configurable lock function. The lock includes a removable and user accessible actuator which when removed from the lock disables a lock function, and when inserted into the lock enables the lock function. Removal of the actuator places the lock in a disabled condition in which the lock cannot be locked by other means. Insertion of the actuator into the lock places the lock in an enabled condition in which the lock is locked or unlocked by the position of the actuator. The lock is installed without the actuator when the lock is intended to be used only in a passage operation where the door provides access only, but does not restrict access. The lock is installed with the actuator when the lock is intended to be used in a privacy operation where the lock is intended to restrict access to an area.

The present invention relates to an anti-barricade door handle assembly which comprises an integrated auxiliary door handle for use in an emergency. The auxiliary door handle can be configured between a stowed configuration and an activated configuration. The auxiliary door handle is operable to operate a lock when in the activated configuration and inoperable when in the stowed configuration. The auxiliary door handle can only be configured to the activated configuration by an authorized user. The auxiliary door handle is configured to override a primary door handle which operates the lock in normal, non-emergency use.

A multifunction securing mechanism for a compartment closable by a door and includes a key cylinder, a latching assembly which may be a two-point latching assembly movable between a latching and an unlatching position, a rotatable member configured for a lazy-cam function connecting the key cylinder and latching assembly, at least one catch located on a surface adjacent the outside of the door, and a bar pivotally mounted to the outside of the door and movable between a first closed position and a second opened position. A first release mechanism is located on an interior side of the door for changing a positon of the latching assembly, and a second release mechanism is located on the interior side of the door for changing a position of the bar, both for allowing a user to open a latched and secured door from the inside.
