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. |
