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.

The invention relates to a device (200) for locking a door, which comprises: a bolt (40) comprising a bar (52) configured to engage in a housing secured to the frame (80) accommodating the door and a pusher means secured to the bar (41) and spaced apart from the bar by a stem and in which the bolt is positioned on the door at a height relative to the foot of the door of between thirty and eighty centimetres, such that the bar of the bolt can be engaged with or disengaged from the housing secured to the frame by pressure applied by a user's knee against the pusher means.

A device includes a door latch activator configured to disengage a door latch from a door frame and a door handle coupled to the door latch activator and configured to activate the door latch activator to disengage the door latch from the door frame. The device further includes a movable plunger having a first end coupled to the door latch activator and adapted to activate the door latch activator to disengage the door latch from the door frame, and an arm rest coupled to a second end of the plunger. The second end is opposite the first end, and the arm rest includes a base region adapted to receive a downward force to engage the plunger. When the base region engages the plunger, the plunger causes the door latch activator to disengage the door latch from the door frame. The plunger may be spring-activated.

The present gate includes a barrier frame and a gate in the barrier frame. The gate is opened by inserting a foot into a foot opening in the gate, which action compresses springs disposed about pivot pins between the gate and the barrier frame and draws an extended latch downwardly and out of a latch receiver that is bottomless, which action unlatches and frees the gate from the barrier frame such that the gate can be swung open. Downward travel of the gate is minimized until a foot pushes a pivoting stop out of the way.

Apparatuses, systems, and methods are provided for detecting an alert status of a locking apparatus for an entry point. An external force may be received at a locking apparatus operating in a locked state and determining a first indicia corresponding to the received external force, separately receiving an indication of the external force at an accelerometer of the locking apparatus and determining a second indicia corresponding to the received indication of the external force, comparing the first indicia and the second indicia to determine an alert condition, and selectively performing at least one alert operation corresponding to the determined alert condition.

A lock mechanism includes a pedal, a vertical rod, a rod support, a hinge, a hinge support, a hinge lock, and magnets. When the pedal is pushed up the vertical rod, the hinge will lower into a cavity of the hinge lock and the lock mechanism will be in a “locked” mode. To “unlock” the lock mechanism, the user pushes the pedal down the vertical rod, then the hinge will raise out of the cavity of the hinge lock and now the lock mechanism will be in an “unlocked” mode. Then when the user wants to lock the lock mechanism while being inside a bathroom stall, the user will align a door with a wall/stand of the bathroom stall and then push the pedal up so the hinge will lower into the cavity of the hinge lock and the lock mechanism will be in a “locked” mode.

A foot operated door opener device that includes a pair of pedals near the lower corner of the door below the door knob/lever. The pedals are connected to a shaft that pivots within housings that are mounted to either side of the door across from one another. The pedal is hooked to a flexible strap or cable that runs vertically up to the knob/lever horizontal shaft. The cable or strap is connected and wrapped around the rotatable knob/lever shaft. As the operator depresses the pedal the cable or strap is pulled downward and rotates the knob/lever unlatching the door. The pedal is pulled or pushed by the operators' foot/shoe to open. Once the operator is through the doorway, the operator can close and re-latch the door by pulling or pushing the door pedal by foot without ever having to touch the knob/lever handle with their hands.

A foot operated door opener comprises a front panel, a rear panel and an anti-slippery structure formed on the front panel. The front panel and the rear panel are connected and pivotally rotated through a hollow connecting tube of the front panel and two fixing tubes of the real panel. The present invention provides user's foot enough tension or fiction to easily flip or rotate the front panel from the rear panel in a folded or unfolded condition and push or pull the door along with the foot. The door will be hence opened simply by user's foot without their hands touching it. This could benefit the user with both hands holding and carrying stuffs and also could prevent germs or bacterial infection by not touching the door.

A door latch operating device that is a safer door handle alternative to a traditional door knob or handle. This device includes a door handle offering numerous surfaces that a person can use to operate the door latch using his or her foot, elbow, knee or handy object such as an umbrella or handbag

A hands-free door opening system for opening doors without contact includes a foot pull apparatus and a hands-free door hardware apparatus. The foot pull apparatus comprises a pull plate coupled to a door. A pull body coupled to the pull plate and the pull plate define a pull cavity dimensioned to receive a user's foot. The hands-free door hardware apparatus comprises a sensor housing coupled to a wall adjacent the door. A fob sensor is coupled within the sensor housing to recognize the presence of an authorized key fob. A transmitter is coupled within the sensor housing and is in operational communication with the fob sensor. An electronic door handle is coupled within the door and has a receiver in communication with the transmitter to disengage when the authorized key fob is detected.
