<p>An espagnolette lock which, on the one hand, requires only low actuating forces and, on the other hand, permits the identical lock to be actuated by means of a cipher-bit key, a security cylinder, a cylinder olive or rotary grip, whereby various components must be interchanged, but in which the basic structure of the lock remains always unchanged. The lock includes an actuating pin of a nut formed so as to at least approximate a circular eccentric pin which, at least in proximity to the axis of symmetry of a locking plate, connects with the latter so as to, upon rotation of the nut through an angle of 180 DEG , forcibly moves the plate out of its opened condition into its locking condition, and vise versa, and arrests the latter in the open-and locked positions.</p> |
