An apparatus for controlling pivoted closing systems in which the controls (1') for the drive means (4) of a mobile closing structure (2) are two cam elements (11, 12), whose active profile (H11, H12) lies parallel with the axis of rotation (X) of the mobile structure (2), the two cam elements being attached to a support (10) which is fixed to the axis (X) and may be separated by an angle determined according to the preset value ( alpha ), and cam element interception means (13), fixed to the mobile structure (2), which interact with the cam elements (11, 12) in a direction (X13) parallel with the axis (X) and can have at least two configurations, so as to allow the drive means to pass from a first to a second speed. <IMAGE> |
