EP0000003 A1 Abstract: A combination lock, particularly a domestic door lock, comprises a rotable and axially movable plunger (14), a plurality of axially displaceable pins (17, 17a) disposed around the plunger (14), a rotary ward disc carried by the plunger slots (19, 20, 21) in the pins (17, 17a) to allow rotary movement of the plunger (14) only when selected ones of the pins (17a) are axially displaced relative to the remainder of the pins (17), to have slots (19) therein aligned with the ward disc (18), and a member (23, 24) carried by the plunger (14) and capable of moving the pins (17, 17a) to an aligned position upon axial movement of the plunger (14). A user can move said selected pins (17a) to render the plunger (14) turnable to open the door and then easily pull or push the plunger to cause said member (23, 24) to re-align the pins (17, 17a) to prevent the selected pins (17a) remaining depressed and the "combination" visible.
