A latch mechanism includes a hook-handle assembly coupled to a first panel and a clevis coupled to a second panel. The hook-handle assembly engages the clevis to secure the first panel relative to the second panel.

A door security assembly for blockading a door in a lockdown situation includes a blockade device. An element of the blockade device insertable into a gap defined by a door and a crash bar that is engaged to the door. Each of a pair of fasteners engaged to the blockade device is selectively engageable the crash bar, so that the blockade device is reversibly engaged to the crash bar with the element positioned in the gap. The blockade device prevents actuation of the crash bar so that the door cannot be opened. The fasteners are positioned so that two hands are required to simultaneously disengage the fasteners from the crash bar to enable disengagement of the blockade device from the crash bar.

An assembly can include a chassis that includes a chamber and an opening; a cover movable for access to the chamber via the opening; a cover latch; and a cover latch release that includes a push panel operatively coupled via a linkage to a pull panel that includes a finger grip surface, where the linkage rotates the pull panel responsive to rotation of the push panel to expose the finger grip surface, and where further rotation of the pull panel releases the cover latch.

A drawer release mechanism has a handle having ends, a cylindrical portion and a flange. A pair of end cap interfaces are engaged to the ends of the handle. The end cap interfaces have rotational shafts, cylindrical receiving portions, receiving slots, and flange slots. A pair of end caps are exterior to the end cap interfaces, the end caps have flange recesses, rotation surfaces, shaft openings, and cam receiving areas, where the rotational shafts are disposed through the shaft openings, the receiving portions are adjacent to the rotation surfaces, and the flange slots are disposed in the flange recesses. The end caps are attached to a drawer. A cam is engaged to each of the rotational shafts. Each cam includes a shaft receiver, an actuator support and a cam actuator. The cams engage levers to release a drawer from a cabinet upon actuation of the handle.

Disclosed is a security device for securing a deadbolt door lock having an interior face plate and a lever movable between a locked position and an unlocked position. The security device includes a base member configured to be secured to the interior face plate of the deadbolt lock, and a lock member pivotably secured to the base member so that the lock member pivots between an open position and a closed position. The lock member is configured to prevent movement of the lever from the locked position to the unlocked position when the lock member is in the closed position and to permit movement of the lever from the locked position to the unlocked position when the lock member is in the open position.

An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state is disclosed. The interchangeable electro-mechanical lock core may include a moveable plug having a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which corresponds to the lock device being in the unlocked state. The interchangeable electro-mechanical lock core may include a core keeper moveably coupled to a lock core body. The core keeper may be positionable in a retain position wherein the core keeper extends beyond an envelope of lock core body to hold the lock core body in an opening of the lock device and a remove position wherein the core keeper is retracted relative to retain position to permit removal.

Locking device is disclosed for parcel boxes or lockers. The device comprises a user operable handle and a lock mechanism comprising a motor to rotate a pinion to move a rack attached to a handle-blocker and to a deadbolt. The handle-blocker controls transition of the user operable handle between open and closed positions due to movement of the rack, and simultaneously the deadbolt is configured to move between locking and unlocking positions. In the closed position, the handle-blocker and the handle-body have a linear connection with each other and in open position this connection is lost. The handle may be activated by tapping the handle-cover, or by using an RFID, NFC or by mobile technologies. A method to operate opening and closing a parcel box locked with the locking device allows one or more users to access the parcel box via software application paired with the device.

A lockset with a sliding spindle assembly allows ingress using a key on the outside or a button on the inside. The sliding spindle assembly provides first and second sliding mechanisms operated from the outside and inside, respectively, that operate a clutch to couple the outside handle to the main spindle. Each sliding mechanism comprises a key cylinder or twist and/or push button lock that rotates a cam to linearly advance (slide) a cam follower that incorporates a spindle receiver. The first sliding mechanism slides its spindle receiver between clutching and non-clutching positions with respect to the main spindle. The second sliding mechanism slides the main spindle itself between clutching and non-clutching positions with respect to the first sliding mechanism's spindle receiver. The sliding spindle assembly can be incorporated into a legacy lockset and also be used in a double-latch lockset.

An actuating device (12) comprising a stationary structure (20); an actuating element (22) rotatable relative to the stationary structure (20); an electric power source (24, 82); a spindle (26) arranged to be rotated by rotation of the actuating element (22); a locking member (28) movable between a locked position (66) and an unlocked position (86); an electromechanical transfer device (30, 84) arranged in the spindle (26), the transfer device (30, 84) being configured to adopt a locked state (68) and an unlocked state (78); a receiver device (34) fixed with respect to the spindle (26), the receiver device (34) being electrically connected 62 to the transfer device (30, 84); and a transmitter device (32) fixed with respect to the stationary structure (20) and arranged to be electrically powered by the power source (24, 82), the transmitter device (32) being configured to wirelessly transmit power to the receiver device (34).
