    摘要： Latch and lock structure for a door wherein the latch includes a bolt and is pivotally mounted upon the door for movement around an axis substantially perpendicular to the plane of the door when it is in its closed position. The latch has an end portion with a recess opening radially of said axis. A bracket is secured to the door for engagement by the latch when it is in the latch position. An L-shaped lever is pivotally secured to the bracket and has an abutment on one leg thereof which is receivable into said recess when said latch is in the latched position. Actuating means engages the other leg of said L-shaped lever for pivoting same and thereby moving said abutment out of said recess. Resilient means yieldably urges said abutment means into the locked position, said actuating means limiting the amount of said urging.
