  • Patent number: 8925979
    Abstract: A latching system for releasably securing a first member to a second member in a closed position. The latching system includes a command latch assembly comprising a hook latch assembly including a handle selectively moveable from a first handle position toward a second handle position and a hook member adapted to selectively engage a first keeper when the handle is in the first handle position and to disengage from the first keeper when the handle is moved to the second handle position. The latching system also includes a remotely located slave latch assembly comprising a pin latch assembly adapted to secure a second keeper to the pin latch assembly when the handle of the hook latch assembly is in the first handle position and to disengage the second keeper when the handle of the hook latch assembly is moved to the second handle position.

  • Patent number: 7185926
    Abstract: A latch mechanism for releasably latching a first member to a second member. The latch mechanism includes a bracket adapted to be attached to the first member and bolt pivotally coupled to the bracket. A handle is pivotally coupled to the bracket and is operatively associated with the bolt such that the handle selectively pivots the bolt between a latched and unlatched position. A trigger is pivotally coupled to the handle and a locking member is pivotally coupled to the trigger. The locking member is adapted to releasably couple the trigger to the bracket to prevent pivotal movement of the handle and the bolt from the latched position. The trigger includes the tool receiving recess such that the latch mechanism may be moved between the latched and unlatched positions with the mechanical advantage provided by the tool.
