The present disclosure is directed to a flight deck barrier apparatus or device including a frame having a first jamb, a second jamb, and a header. A foldable barrier mechanically coupled to the second jamb. An edge beam mechanically coupled to the foldable barrier. The edge beam configured to mechanically cooperate with strikers along the first jamb and mechanically cooperate with strikers along the second jamb. The edge beam including a plurality of catches. Respective ones of the plurality of catches interlock with corresponding ones of the strikers along the first jamb when the foldable barrier is in a stowed position such that a flight deck of an aircraft is accessible. Respective ones of the plurality of catches interlock with corresponding ones of the strikers along the second jamb when the foldable barrier is in an expanded position limiting access to the flight deck barrier of the aircraft.

A lock assembly including a plurality of button assemblies having a plurality of indicator elements. A position of the indicator elements sets a lock combination. A code blocker is configured to cover and prevent access to the plurality of button assemblies when the lock assembly is in a first position, for example in an unlocked position, and to allow access to the plurality of button assemblies when the lock assembly is in a second position, for example in a locked position.

The pushbutton combination lock has a lock bolt mechanism with a lock bolt movably mounted on a frame between a locking position and an unlocking position. The lock bolt mechanism further has two lock bolt actuating mechanisms arranged to move the lock bolt between the locking position and the unlocking position. The lock has a pushbutton combination locking mechanism for locking the first lock bolt actuating mechanism to prevent the lock bolt from being moved by the first lock bolt actuating mechanism to the unlocking position while the second lock bolt actuating mechanism is independent from the pushbutton combination locking mechanism. The pushbutton combination locking mechanism is further rotatably or slidably mounted to the frame such that the user can choose the side for locking and the side for free operation.

A combination faux switch and sliding bolt lock, one or more imitation switches mounted on a cover to an enclosure, the cover and switches resembling a circuit breaker panel, each switch having a toggle arm including a back portion disposed in the enclosure behind the cover, manipulation of the toggle arm moving the back portion between first and second positions, the back portion slidably attached to a bolt one end of which is received in an aperture in the side walls of the enclosure locking the cover to the enclosure. One embodiment of the invention includes a plurality of combination faux switched and sliding bolts such that a locking combination may consist of any combination of the switches appearing to be in “off” or “on” positions.

A lock includes a housing having a plurality of apertures receiving buttons. A biasing member biases each button towards an un-pressed position. A plurality of spools includes circumferential grooves. Each circumferential groove has a notch that is angularly displaced relative to each of the other notches on that spool. A plurality of legs is in communication with one of the buttons and contacts one of the circumferential grooves. A locking plate includes apertures receiving the spools. An actuator is associated with the locking plate and a latch. Pressing and releasing the buttons causes translation of the spool rotationally orienting a notch to be adjacent to the locking plate. The locking plate only moves into an unlocked position, when driven by the actuator disengaging the latch and unlocking the lock if all of the notches which are adjacent to the locking plate are in a unlocked rotational orientation.

A keyless gate latch to selectively latch a gate to a post wherein the keyless gate latch comprises a keeper assembly including a keeper member having a keeper stop movable between a latched position and an unlatched position normally biased in the latched position and a latch assembly including an actuator lever rotatably between a latched position and an unlatched position at least partially disposed within a housing and including a latch stop such that when the latch member and the actuator lever are each in the latched position, the keeper stop and the latch stop when engaged with each other prevent the gate from being opened and when the actuator lever is rotated from the latched position to the unlatched position the actuator lever engages the latch member moving the latch member from the latched position to the unlatched position preventing the keeper stop from engaging the latch stop allowing the gate to be opened.

A drawstring lock includes a housing that allows the two ends of a drawstring to pass through, a stop mechanism disposed on the housing, and a lock mechanism connected to the stop mechanism. The housing is able to shift freely along the drawstring and once reaching its desired position, it is able to operate the stop mechanism so that the housing is stopped and cannot be shifted. Subsequently, the lock mechanism is used to lock the stop mechanism, keeping it secured until the lock mechanism is unlocked.
