Abstract: A security indicator has a two part telescopic locking bar attached to the handle of a door at one end and to the door or door jamb at the other end through an end piece. The device includes a cup or tube which encases the door handle, preventing use of the handle. The length of the bar is fixed by aligning apertures in each part of the telescopic locking bar to form a continuous aperture, inserting a frangible pin through the continuous aperture and locking the frangible pin in place with a padlock received by a hole in the frangible pin. The pin has a narrow portion which can be broken by relatively little human force. The device requires someone who does not have the key to the padlock on the frangible pin to break the frangible pin to enter a door fixed with the device. A broken pin alerts the occupant that an entry has occurred during his/her absence. A sleeve normally protects the narrow portion but slides easily away to expose the narrow portion when entry is desired.

Abstract: An improved secure latch for a fixture having a door with a double-wall structure, including an endwall with an exit port and an inner sidewall with a slot near the endwall and parallel thereto. An entry port of a facing member and an orifice of a tongue, slidably receivable through the slot, of a latch attached to the facing member are aligned with the exit port as the door is in a closed configuration such that a bolt of a lock installed in the door is slidable therethrough as the bolt is displaced between a locked configuration and an unlocked configuration. The secure latch is adapted to retain the door in a closed configuration as the bolt is in a locked configuration even though the facing member may be forced clear of the bolt. Further, the secure latch prevents the lock from being sprung open without inflicting severe and visible damage to the door and/or the facing member. A modified embodiment provides the endwall without the exit port and the facing member without the entry port.

Abstract: A vehicle door is provided including a latching mechanism carried by the door constructed and arranged to move between an unlatched relation with a door opening catch and a latched relation with the door opening catch. The latching mechanism includes a movable releasing component constructed and arranged to be in a latching position within the door structure when the latching mechanism is in latched relation with the door opening catch and to be moved from the latching position in a generally downward direction into a releasing position to move the latching mechanism into unlatched relation with the door opening catch. A motion-transmitting assembly is disposed within a space defined by the door to transmit a manual motion of an external door handle to downward motion of the movable releasing component.

Abstract: An apparatus for locking an aircraft door provided in the outer wall of an aircraft includes at least one locking shaft pin that locks the aircraft door in a fixed, closed position relative to the outer wall of the aircraft when the locking shaft pin is positioned or rotated into a locking position. The locking shaft pin is connected to a mechanical linkage forming a positioning arrangement. The positioning arrangement is coupled to a control element, which essentially includes a membrane connected to a control rod. The membrane is arranged within a housing so as to form an interior air chamber on one side of the membrane and an exterior air chamber on the other side of the membrane. The air pressure of the cabin interior is applied to the interior air chamber through an interior air pressure port, and the exterior ambient air pressure is applied to the exterior air chamber through an exterior air pressure port.

Abstract: The Earthquake Actuated Door Latch mounts outside a cabinet or beside the cabinet door. The device contains a pivoted catch assembly with a weight on one end and a door catch, or hook, on the other. The catch assembly is stable in two positions, one on each side of the cabinet door. An earth tremor causes the weight to shift out of the cocked position to the operated position (the second stable position) putting the hook where it interferes with opening of the cabinet door. Weight and hook move as a unit, minimizing delay, and an internal lock prevents rebound.
