Abstract
The latch or bolt (4) of a door lock is engaged and driven by a finger (24) on a control arm (22), pivoted on a pin (20) fixed to the case (12) of the lock. The control arm is driven by a cylindrical sliding member (36) engaging a tab (32) thereof; this member in turn is driven against a spring action (40) along a fixed guide shaft (38), which is coaxial to it, by a control lever (42) hinged on a fixed pin (44) in the lock case, whose axis intersects the axis of the cylindrical sliding member. Control lever head (42') is sufficiently extended to engage two diametrically opposite parts of the cylinder, in rest position.
