<p>The fitting is for a single handle window, and comprises a central lock with control housing, one or more angle linkages, and control rods with locking devices working with catches fixed to the frame. There is an angle bearing forming the bottom hinge, and an articulated link limits the amount for which the window can tilt open and acts as a hinge when it swings open. The fitting is mounted between the central lock and the horizontal arm of the articulated link, and incorporates a coupling lever (40) unfolding in a direction opposite to that of the horizontal link arm (31). The lever contains a hole (49) whose straight portion is parallel to the working direction of the control rods.</p> |
