Abstract: A latch mechanism for use in attaching portions or panels on an aircraft. The latch mechanism and related method include a detent mechanism for releasably coupling a bolt portion of the latch to a handle portion of the latch. The latch allows the bolt and handle to conjointly pivot with respect to a corresponding mounting bracket. The latch operates to relieve pressure in an excess pressure condition when the forces associated with the detention mechanism are overcome.

Abstract: An apparatus, system and method including a latching device (24) for displaceably retaining a panel (40) relative to a frame (32). The latching device includes at least a bolt (78) 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 (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 oppposite, sides of the panel or when a pressure decrease occurs on one side of the panel.

Abstract: A damping device using viscous shear to moderate substantially linear movement. The device has a housing with one or more reservoirs containing a viscous fluid, such as silicone, and one or more retractable struts that can extend from the housing. The strut has a portion formed as a toothed rack, and an associated axle has a pinion gear on a portion associated with the toothed rack of the strut. The teeth of the rack mate with teeth of the pinion gear. A disk, or preferably series of spaced disks, can be mounted on the axle inside the reservoir to dampen linear movement of the strut, from shear with a static plate adjacent to the disk on the axle. The relatively fixed, spaced disks or plates are adjacent to or interdigitated with the disks on the gear axles to dampen linear movement of a strut.

Abstract: A latch system including a first portion and a second portion which are attached to corresponding pieces. The first portion is engageable with the second portion. A drive device is coupled to at least one of the first portion and the second portion for controllable operation of the device to engage and disengage the first portion and second portion. A controller is provided and coupled to the drive device for controllably operating the drive device to engage and disengage the latch. The first and second portion may be provided in the form of a hook and keeper configuration with one of the hook portion and keeper portion being driven by the drive device. A sensor may be provided on the latch assembly coupled to the controller for detecting at least one condition such as the latch being engaged or the latch being disengaged. Also disclosed is a method of latching using a first portion, second portion, drive device and controller for controllably latching and unlatching a latch assembly.

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 translation: 一种用于将面板保持在关闭位置并且在施加由与面板相邻的区域中的压力变化引起的变化时释放面板的方法和装置。 该装置包括附接到具有用于接合相应面板的螺栓的结构的闩锁机构。 闩锁机构可以被保持在相应的面板上，螺栓与结构接合。 提供压力响应装置以检测面板一侧的压力变化，并且有助于响应于预定范围或力的压力变化释放螺栓。 闩锁机构和压力响应装置仅与面板的一侧排放或连通。 面板一侧的储存器与压力响应装置的压力响应室相通。 储存器通常在面板的同一侧上，以提供通常与环境压力隔离的压力体积，例如在减压事件期间。 该方法包括一种将锁定机构保持在受压变化的关闭位置的方法，包括仅感测面板一侧的压力变化。
