Equipment e.g. hinge plate, for controlling opening of window leaf chassis with respect to door frame chassis in building, has striker receiving joint ball so that actuation of bolt causes rotation of arm to exert force to open leaf chassis

摘要

The equipment (1) has a mobile control rod (5) actuated in translation via a peripheral linkage (6) by a lock bolt (7) of a window leaf (2) of a window. An articulated arm (8) is integrated to the mobile rod. A striker receives a joint ball (11) of the arm in a closing position of the leaf, so that actuation of the lock bolt for opening causes rotation of the arm in a direction to exert a pushed force on the striker when the leaf is in the closing position for opening of a chassis of the leaf around a rotation axis of the leaf.
