VERRIEGELUNGSVORRICHTUNG AN KOKSOFENTUEREN

摘要

By providing a single biasing element (spring) connected through pull rods to toggle means in laterally-inverted relationship, there are overcome the problems of (1) inequality of forces on the latching beams and (2) the need for relatively massive springs. The toggle means provide a force-multiplying effect. Moreover, no special actuating element is required for latching or unlatching.
