<p>A latch is disclosed comprising a casing adapted to be fixedly mounted in a door. A carriage is mounted in the casing and adapted for sildable movement relative to the casing between an actuated position and a return position. A first spring biases the carriage to the return position and a lock bolt mounted to the carriage is biased to protrude from the casing when the carriage is in the return position. A master cam and a slave cam are each pivotally mounted to the casing such that the master cam directly acts upon the slave cam which in turn actuates the sliding movement of the carriage from the return position to the actuated position.</p> |
