초록 ▼

An automatic door latch has a case and a bolt movable within the case between a fully extended position in which the bolt extends forwardly of the case and a partially extended position in which the bolt is positioned to contact a door strike. There is a plunger mounted on the bolt, with the bolt and plunger being relatively movable. A spring biases the bolt toward a fully extended position and a spring biases the plunger outwardly of the case. The plunger has a projection which limits outward movement of the plunger to a position in which its extension is the same as that of the bolt when it is in its partially extended position. There is a stop on the bolt movable toward and away from the case and there are projections on the case which coact with the bolt stop to limit bolt extension to its partially extended position. The plunger has a cam cooperating with the bolt stop to cause movement of the stop away from the case and toward the bolt during outward movement of the bolt relative to the plunger to permit the bolt to move to a fully extended position.
