Abstract
Safety-drum antipanic lock comprising a bolt (3, 103), an actuating rod pivotingly connected to the door, at each of its ends, by means of a unit formed by a housing (1, 101) fixed onto said door and a lever (2, 102) pivotingly mounted, in said housing (1, 101), at least one lever (2, 102) being an actuating lever cooperating with components of its housing (1, 101) to actuate the bolt (3, 103). The housing (1, 101) of the actuating lever (2, 102) is associated with at least a safety-drum (19, 20; 120) driving a bit (21, 23; 151) co-operating with actuating means for said housing to actuate the bolt (3, 103). Said housing (1, 101) of the actuating lever (2, 102) comprises at least two different operating means (14, 15a, 15b; 114) capable of separately co-operating each with a drum (19, 20; 120) to actuate said bolt (3, 103).
