Abstract: A latch including a housing having side members each having an elongated slot, a bolt mounted rotatably to the housing and positioned between the side members of the housing, a trigger mounted rotatably to the housing, and a pin and roller positioned slidably within the elongated slots of the side members of the housing. The bolt is moveable between a first, closed position and a second open position. The trigger is moveable between a first position, in which the pin and roller are engaged with the bolt when the bolt is in its first position, and a second position, in which the pin and roller are disengaged from the bolt. The latch can be opened automatically when a defined load is provided on the bolt, or manually by depressing the trigger to disengage the pin and roller from the bolt.

Abstract: A handle mechanism includes a gear drive having an interior end and an exterior end; an inside handle fixed to the interior end; a button; a finger; a handle drive; an outside handle; and a spring. The button has an interior end and an exterior end, which is positioned within the exterior end of the gear drive. The handle drive is positioned within the exterior end of the gear drive and is rotatable relative thereto. The outside handle and the handle drive rotate together. The outside handle moves between a first position, wherein it is constrained from rotation, and a second position. The finger is fixed to the exterior end of the button, which moves between a first position, wherein the finger causes the gear drive and the handle drive to rotate together, and a second position. The spring biases the button and the outside handle toward their first positions.

Abstract: A latch including a housing having a cylinder, a compression spring positioned within the cylinder, and a ball positioned at one end of the compression spring, a hook positioned slidably within the housing, and a star wheel positioned around the hook and having a plurality of holes formed therein. The ball under load from the spring aligns with and engages one of the holes of the star wheel to retain it in place. The star wheel is moveable rotatably such that the ball disengages the one of the holes of the star wheel to enable the hook to move axially and be adjusted relative to the housing, and the ball is adapted to engage another of the holes of the star wheel to retain the star wheel and prevent inadvertent rotation.
