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.

A smart-lock system and a method of operating the system is disclosed. The system comprises a smart-lock on a door of a room. The door comprises a first and a second side. The first side of the door lies on the interior side of the room and the second side of the door lies on the exterior side of the room. At least one sensor is disposed on the first side of the door to detect the presence of any user on the interior side of the room and at least one sensor is disposed on the second side of the door to detect the presence of any user at the exterior side of the room. The smart-lock is configured to lock the room when the room is occupied.

A door module for use with a door system, and applications thereof, are disclosed. The door module comprises a door frame and a door articulated to the door frame, a touchless door module comprising a door motor assembly, a door locking assembly, a control assembly and a power source. The door motor assembly can be configured for displacing the door between an open position and a closed position, responsive to a door opening signal or a door closing signal, respectively, emitted from the control assembly. The locking assembly can be configured for displacing a locking bolt between a locked position at which it is engageable with a locking strike, responsive to a locking signal emitted from the control assembly, and an unlocked position, responsive to an unlocking signal emitted from the control assembly. The control assembly comprises in some embodiments at least one touchless inside sensor, wherein an entrance signal includes a signal received form the at least one inside touchless sensor, resulting in generating a door closing signal and an occupied signal, and an exit signal received by the at least one inside sensor resulting in generating a door opening signal. The control assembly may further comprise a signaling system configured for emitting noticeable door mode indicia responsive to door parameters.

A status indicator for a locking mechanism may include a status indicator face, a status indicator plate, a cam coupling, and a locking mechanism coupler. The status indicator face and status indicator plate may be at least partially moveable relative to one another. The locking mechanism coupler may have a greater rotational range of motion than the cam coupling. The status indicator face may indicate the state of a locking mechanism and may have a viewing angle greater than or equal to 180 degrees.

The present application provides a lock (100) for a door. The lock comprises a housing (102), a lock mechanism (108), and a bolt (104). An end portion (112) of the bolt comprises a trigger (106). The lock mechanism is operable to move the bolt between a locked position in which the end portion extends through an opening in the housing and projects from the housing, and an unlocked position in which the end portion is within the housing. The lock further comprises a retraction mechanism (110), wherein actuation of trigger causes the retraction mechanism to automatically move the bolt from the locked position into the unlocked position.

A latching system and method are configured to selectively latch and unlatch a first component in relation to a second component. The latching system and method include an actuator, a first coupler secured to the actuator, a latch, and a second coupler secured to the latch. The first coupler is configured to couple to the second coupler to couple the actuator to the latch. The first coupler is configured to uncouple from the second coupler to uncouple the actuator from the latch in response to the latch being manually operated.

The present disclosure is directed to a bi-fold door system, apparatus, or device including a first panel, a second panel, and a center post. When in a fully closed position, the bi-fold door limits access to a lavatory on an aircraft, and, alternatively, when in a fully opened position, the bi-fold door allows or provides access to the lavatory on the aircraft. When in the closed position, a user within the lavatory may lock the bi-fold door in the closed position by stepping on a foot pedal at an interior of the bi-fold door. The foot pedal mechanically cooperates with a lock rod and an escapement mechanism the user stepping on the foot pedal moves the lock rod from a retracted position to an extended position locking the bi-fold door in the closed position. To exit the lavatory, the user may unlock the bi-fold door utilizing the foot pedal and then interact with a hands-free actuation mechanism to move the bi-fold door from the closed position to the opened position. When in the opened position, the bi-fold door may be held open for a selected period of time such that the user may exit the lavatory without physically contacting the bi-fold door.

A latch is provided for latching the doors of cubicles or stalls provided in public washrooms. The latch includes a body mounted within a cavity formed between the inner and outer door surfaces, the body rotatably mounting a spindle having a latching member mounted at one end. Biasing means in the form of one or more cam followers acting on a corresponding number of cam surfaces is provided between the body and the spindle to hold the spindle in a closed position but, once displaced from the closed position, to bias the spindle toward a fully open position.

A method for controlling actuations of an automatic toilet flushing mechanism compares manual flush timestamps, latch open timestamps and latch close timestamps in association with uses of a toilet stall to generate a stall use profile. Automatic toilet flushing may be controlled based on the stall use profile. Stall usage data, toilet usage data and/or water usage data may be collected and provided for improved maintenance and water conservation.
