Abstract: An apparatus, system and method including a latching device for displaceably retaining a panel relative to a frame. The latching device includes at least a bolt which is carried on the latching device and is operatively associated with the panel to prevent disengagement of the panel. The latching device includes at least one pressure responsive device operatively coupled to the bolt to retain the bolt in a desired position and release the bolt when a predetermined pressure differential occurs relative to two, generally opposite, sides of the panel or when a pressure decrease occurs on one side of the panel.

Abstract: A method and apparatus for maintaining a panel in a closed position and releasing a panel upon application of changes resulting from a pressure change in an area adjoining the panel. The apparatus includes a latch mechanism attached to a structure having a bolt for engaging corresponding panel. The latch mechanism may be retained on the corresponding panel with the bolt engaging the structure. A pressure responsive device is provided to detect a change in pressure on one side of the panel and facilitating release of the bolt in response to a pressure change of a predetermined range or force. The latch mechanism and pressure responsive device vent to or communicate with only one side of the panel. A reservoir on one side of the panel communicates with a pressure responsive chamber of the pressure responsive device. The reservoir is generally on the same side of the panel to provide a pressure volume which is generally isolated from ambient pressure, such as during a decompression event. The method includes a method of maintaining a latch mechanism in a closed position subject to a pressure change, including sensing the pressure change on only one side of the panel.

Abstract: A method and apparatus for maintaining a panel (40) in a closed position and releasing a panel upon application of changes resulting from a pressure change in an area adjoining the panel. The apparatus includes a latch mechanism (24) attached to a structure having a bolt (60) for engaging corresponding panel. The latch mechanism may be retained on the corresponding panel with the bolt engaging the structure. A pressure responsive device (66) is provided to detect a change in pressure on one side of the panel and facilitating release of the bolt in response to a pressure change of a predetermined range or force. The latch mechanism and pressure responsive device vent to or communicate with only one side of the panel. A reservoir (93) on one side of the panel communicates with a pressure responsive chamber of the pressure responsive device. The reservoir is generally on the same side of the panel to provide a pressure volume which is generally isolated from ambient pressure, such as during a decompression event. The method includes a method of maintaining a latch mechanism in a closed position subject to a pressure change, including sensing the pressure change on only one side of the panel.

Abstract: An apparatus, system and method including a latching device for displaceably retaining a panel relative to a frame (24). The latching device includes at least one bolt (79) which is carried on the latching device and is operative ly associated with the panel to prevent disengagement of the panel. The latchin g device includes at least one pressure responsive device (26) operatively coupled to the bolt to retain the bolt in a desired position and release the bolt when a predetermined pressure differential occurs relative to two, generally opposite, sides of the panel when a pressure decrease (P1, P2) occurs on one side of the panel.
