A housing (15) of an espagnolette lock comprises, beside an ordinary rotatable member (16) for actuation of an operating rod (12) for fastening members (13), a second rotatable member (21), which is adapted for cooperation with a cylinder lock of conventional type. A displaceable locking bolt (25) extends between the two rotatable members. The second rotatable member (21) is provided with a finger (33), which is in the form of a hook (34) extending into a slot in the bolt, and upon rotation in one direction moves the bolt away from the first rotatable member (16), and which is also formed as a cam (35) for forcing the bolt towards the first rotatable member, upon rotation in the opposite direction. The first rotatable member (16) is provided with an external guiding surface (26) having such peripheral extension, that the bolt (25) can lock the first rotatable member in a certain angular position thereof only, corresponding to a full locking position of the espagnolette. The guiding surface (26) is in this position terminated by a detent (28) for engagement with the bolt. <IMAGE> |
