摘要： A latch for latching a first object with a second object includes a catch attached to the first object. The latch includes a hook portion having a hook which engages with the catch attached to the first object that the latch holds in place. The latch includes a base portion that is fixed to a rigid surface of the second object. The ladder includes a pinch flex portion connected to the base portion and the hook portion. When the pinch flex portion is compressed or pinch flexed downward to the base portion, the hook portion moves off of the first object, thus releasing the first object to move away from the second object. When the first object is to be held or latched to the second object, the first object is moved against a cam portion of the hook portion, pushing the hook portion back away from the first object until the first object clears the hook of the hook portion, whereupon the hook portion no longer being restrained by the first object, under a force bias created in the pinch flex portion by the pinch flex portion being compressed, automatically moves back and catches or latches the first object to the second object without any spring or other component to create the force bias. The latch is one piece. A method for latching a first object to a second object, such as a front rail and a rear rail of a ladder. A ladder.
