  • Publication number: 20140035296
    Abstract: 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.

  • Patent number: 7578475
    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.

  • Patent number: 6913297
    Abstract: A latch mechanism for releasably securing a first structure to a second structure. The latch mechanism includes a housing adapted to be attached to the first structure and an actuator pivotally attached to the housing. Selective pivotal movement of the actuator pivots a bolt member between a latched position and an unlatched position. The latch mechanism is sealed to prevent the flow of fluid through the latch mechanism.

  • Patent number: 6755448
    Abstract: A blowout latch is provided to latch a first panel to a second panel. The latch is coupled to the first panel and engaged with the second panel. The latch includes a biasing mechanism which is disengagable under pressure to move the first panel relative to the second panel. The latch may also be selectively disengaged with a lesser force than that required to overcome the biasing mechanism by bypassing the biasing mechanism. When manually disengaged, the latch maintains a biasing load on a bolt of the latch. A trigger of the latch is provided to bypass the biasing mechanism and disengage a roller assembly of the latch from the second panel.

  • Patent number: 6513841
    Abstract: Disclosed is a blowout latch for releasably securing an aircraft panel to an aircraft structure. The blowout latch includes a housing, a bolt, and a handle. The housing includes a bias section that has a plate, a block adjacent the plate, at least one coil spring having opposing ends, a roller mount, and a roller pin. The roller mount has a roller mount base. One end of the coil spring contacts the roller mount base. The opposing end of the coil spring contacts the block. The roller pin is rotatably mounted to the roller mount. The bolt is rotatably mounted to the housing and is used to engage the aircraft structure. The bolt has a secured position. The bolt is held in its secured position by the coil spring which biases the roller pin against the bolt. The handle is rotatably mounted to the bolt and is moveable between a latched position and an unlatched position, without the use of a tool. The handle provides an indicator when the blowout latch is in an open position.

  • Patent number: 4914783
    Abstract: A sliding hinge for mounting a nose cone or cover on a nacelle or housing, such as an equipment package suspended from the wing of an aircraft. Typically two hinges are used, positioned at opposite sides of the housing, for pivoting the nose cone upward to provide access to the equipment within the housing. Each hinge includes a sleeve mounted in the housing, a slide block sliding in the sleeve, and a slide arm pivotally attached to the slide block and mounted in the nose. To open the package, the nose is initially slid forward from the housing and then pivoted to an upward position. During this operation the slide arm slides out of the sleeve from a retracted position to an extended position and then pivots upward to the open position, with the slide block remaining in the sleeve.

  • Patent number: 4819300
    Abstract: A strut assembly having first and second sections pivotally linked together. An overlying sleeve is extendable to lock the sections together in the extended position and retractable to allow folding of the sections relative to one another. A member is arranged at the joint between sections and biased to extend outwardly into interference with the path of extension of the sleeve. A link linking the first and second sections cooperates with the member to retract same when the strut assembly is collapsed in order that the sleeve will automatically lock the sections together when the assembly is again extended.
