20140035296 | PRESSURE RELIEF LATCH MECHANISM - A latch mechanism having a mounting bracket, a body portion, and a flange portion. The latch mechanism is used for connecting a first and second members. The body portion has walls extending from a flange portion defining a chamber therein. A detent mechanism is positioned in the chamber. A bolt, movably carried on the latch mechanism, has connected front and rear bolt portions and may include a spring biased ball for engaging a recess on the rear bolt in the latched position. A receptacle is defined in the mounting bracket. A head portion of the rear bolt is positioned relative to the receptacle in the latched position. A portion of the rear bolt travels through the receptacle when unlatching and engages the detent mechanism in the latched position. A gasket provided between the head and the receptacle seals the head in the receptacle in the latched position. | 02-06-2014 |
20120242097 | PRESSURE RELIEF LATCH, HIGH REPEATABILITY - A pressure relief latch for use in securing panels on an air-craft. The latch includes an apparatus and method to retain the latch in a latched condition under certain conditions. The latch includes a detention assembly which includes at least a portion which has a coefficient of thermal expansion which differs from a housing of the latch. | 09-27-2012 |
20120242096 | PRESSURE RELIEF LATCH MECHANISM - 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. | 09-27-2012 |
20110101710 | TOOL OPERATED CHANNEL LATCH - A latch mechanism for releaseably latching or holding a first member with respect to a second member in a structure. The latch mechanism includes a bolt assembly, mounting brackets, and a locking trigger. The latch mechanism also includes a rotatable locking cam for providing retention of the bolt assembly in a latched or locked condition. | 05-05-2011 |
20080308366 | VISCOUS SHEAR DAMPING STRUT ASSEMBLY - 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. | 12-18-2008 |
