摘要：
A door latch has an actuating mechanism which retracts the latch tongue by a small amount of rotation of a doorknob. The actuating mechanism includes a wheel rotated by the knob which has a projecting tooth engaging a lever that pulls a plate connected to the latch arm. The lever arm is longer than the tooth.
