<p>A lock mountable to a displaceable wing (1) including a casing (5) and operating means including at least one hand operable unlatching lever (109) operable in an unlatching direction to cause a corresponding unlatching cam (101) to displace in an unlatching direction, an engaging member (7) supported by the casing and displaceable between a fully displaced disposition and a fully retracted disposition, the unlatching cam being operably connected to the engaging member by an angularly displaceable unlatching rocker (87) supported at a pivotal joint (333) disposed between the engaging member and the unlatching cam, the unlatching rocker having a first arm (88) operably associated with an unlatching arm of the unlatching cam and a substantially opposed second arm (90) operably associated with the engaging member, the unlatching cam being displaceable in an unlatching direction to cause unlatching arm to displace the first arm of the rocker to displace the second arm in the opposite direction to thereby cause the engaging member be displaced towards the fully retracted disposition. A lock as described above and including an angularly displaceable driver member (158) having an undisplaced disposition and being connectable to at least one remote engaging member to actuate the remote engaging member, said driver member being displaceable towards the undisplaced disposition by displacement of an unlatching cam in an unlatching direction, said driver member being displaceable from the undisplaced disposition by displacement of an unlatching cam in the opposite direction.</p> |
