The device has a blocking unit i.e. mobile piece, mechanically connected with a striking bar and for cooperating or non-cooperating with a stopper along an orientation of the blocking unit and along orientation units of the blocking unit. The orientation units comprise a cross or star shaped finger (12) and a tipping device (22), and allow intervening for exclusively changing the orientation of the blocking unit when the bar moves along a specific segment in one of two moving directions. A support (11) is located at an end of the striking bar. An independent claim is also included for a screen system comprising a striking bar.
