A door lock system includes an escutcheon with a keyless cylinder handle. A locking block is disposed in the handle cylinder and spring biased to a locked position to prevent removal of the handle. The locking block may only be moved to an unlocked position by accessing a lock spindle extending through an opening on a rear side of the escutcheon mounted to the door.

The present invention relates generally to mechatronic locks and more specifically, and preferably, wireless mechatronic smart lock systems for locking doors which can be operated by a mechanical tool after positive authentication of the user. In a first aspect, there is provided a mechatronic lock system arranged for actuating a door lock operating member for locking and unlocking a door upon activation of said system comprising: an outside lock interface, comprising means for receiving a mechanical tool, arranged for operating said door lock operating member by a user of said lock system upon receiving said mechanical tool; an inner assembly, comprising: a wireless communication unit, arranged for wireless communication with a wireless communication device for authorizing said user; a control unit, in communicative connection with said wireless communication unit and arranged to activate said system for unlocking said door by activating a mechatronic clutch arranged for coupling said outside lock interface to said door lock operating member; wherein said mechatronic clutch is activated upon positive authorization of said user for opening said door by operating said outside lock interface.

A control and information system is for a lavatory of an aircraft, where the lavatory has a door. The system contains a door actuator for opening and closing, a lock actuator for locking and unlocking the door, a control device for controlling the door actuator and the lock actuator, a human-machine interface for actuating the door by a user, as well as a communication interface for exchanging information between an authorized entity and the control device. The lavatory contains a wall structure supporting the door, and the control and information system. A user controls the door via the human-machine interface. Information about the communication interface is exchanged between the control device and the authorized entity.

An exemplary embodiment provides an electric lock, comprising: (a) a knob; (b) a lock body; (c) a rotatable shaft comprising a rotatable-shaft front end and an opposing rotatable-shaft rear end, wherein the rotatable-shaft rear end is fixedly connected to the lock body to control a locking and unlocking of the lock body; (d) a gear assembly comprising a gear and a movable piece with a common axis center; and (e) a motor assembly for driving the gear to rotate. The knob and the rotatable shaft are connected via the movable piece; the movable piece interacts with the gear via a mechanical barrier, such that electrically driving the gear by the motor assembly causes the movable piece to rotate; and the movable piece can pass over the mechanical barrier when a sufficient rotational force is applied to the knob, such that the movable piece is free to rotate relative to the gear, thereby allowing a user to manually control the locking and unlocking of the lock body. In some exemplary embodiments, the provided design of the electric lock structure significantly improves the safety of the electric lock.

An intelligent lock, overlock, and lock system can be electrically controlled to open and close one or more locks. The lock, lock system, and method may function on a frequency selected to avoid cross talk, which permits numerous locks to function simultaneously on the same central system with little interruption or delay. A lock may be used as an overlock for an existing lock or be a primary lock and may include a pivoting engagement structure that engages a locking mechanism to provide added strength.

Apparatus for unlocking and locking a lock (1′) enabling access to protected areas. The apparatus comprises a housing (5) with a housing interior (64). A rotational shaft (30) is in operative connection with the housing. A motor (10) extends in the housing interior (64), is in operative rotational connection with shaft (30) and is operative to rotate the shaft (30). A battery cell (9) extends in the housing interior (64) and is in partially surrounding relation of the motor (10). The battery cell is in operative electrical connection with the motor (10). In cross section, the battery cell (9) includes at least two points (34) and (36) such that a line segment (32) joining these two points passes through the motor (10).

A transmission structure of a rotary shaft of an electronic lock contains: a drive unit which includes a holding plate, a motor, a worm, and a driven wheel. The holding plate includes an externally threaded portion and a fixing orifice. The driven wheel includes an internally threaded orifice, two protrusions, two flat zones, two arcuate fringes, and a tooth section. The transmission unit includes a guide element, a movable element, a resilient element, a retainer, and an acting element. The guiding element has a central orifice, the movable element has a guiding orifice, and the acting element has a slidable post. The frame includes a defining orifice and is welded with the holding plate. The connection seat is received in the defining orifice and includes a retaining portion. After the connection seat is received in the defining orifice, the retaining portion is engaged with a fastening ring.

The present disclosure relates to a bi-directional overrunning clutch, electronic door locks having bi-directional overrunning clutches, and methods of using the same. In certain embodiments, the electronic door lock includes a first locking mechanism for driving an inner wheel through a first torque to rotate a rotatable shaft to operate a locking device on a door by a user from outside, a second locking mechanism for driving inner wheel through the first torque to operate the locking device from an inside, a third locking mechanism for driving an outer wheel rotatable coaxially around the rotatable shaft through a second torque to operate the locking device electronically, and the bi-directional overrunning clutch. When outer wheel rotates at second torque, inner wheel and rotatable shaft rotate along with outer wheel, and when inner wheel rotates at first torque, outer wheel does not rotate along with inner wheel and rotatable shaft.
