Antipanic lock and housing for such a lock

Abstract

The antipanic lock comprises at least a bolt and an actuating rod pivotingly connected to a door by a unit formed by at least two housings fixed onto the door and two levers (2) integral, towards their one end, with the actuating rod and pivotingly mounted, at their other end, into an associated housing (4); said lock comprises a torsion spring (10), in a first dihedron corresponding to a first direction of opening of the door, the actuating rod and the levers (2) towards a neutral position, one of the levers being a control lever co-operating with members in order to actuate the bolt. The first leg of a torsion spring (10) is arranged so as to allow the associated lever (2) to pivot in order to be located in a second dihedron corresponding to a second direction of opening of the door; a second leg of a torsion spring (10) is provided to pull off towards a neutral position, in this second dihedron, an associated lever (2) and the actuating rod, while the bolt control-lever and the members (26) of its housing are arranged so as to further ensure the actuation of the bolt when this control lever had been located in the second dihedron, the lock thus being reversible.
