Abstract:
1. A protection system for motorized pedestrian access passageways, comprising a shaped structure ( 7 ) with at least one seat ( 25 ) situated to a side of an access passageway, a mechanism for the closing or opening of said access passageway, at least one sliding shutter ( 12 ), which moves with an oscillating movement for the closing or opening of the passageway itself, by respectively emerging from or re-entering said at least one seat ( 25 ) of said shaped structure ( 7 ), wherein said mechanism includes a support rod ( 6 ), a lever ( 8 ), a crank ( 22 ), an activation motor ( 23 ) and arms ( 28 ) for supporting and activating said sliding shutter ( 12 ), said sliding shutter ( 12 ) being provided with at least a rod-shaped hooking support ( 18 ) to fix said sliding shutter ( 12 ) to at least one portion of a longitudinal strip ( 17 ) which is entrained by the sliding shutter ( 12 ) along said seat ( 25 ), said longitudinal strip ( 17 ) sliding inside side guides ( 9 , 10 ) provided in prefixed positions of said shaped structure ( 7 ), so as to inhibit access to the seat ( 25 ) when the sliding shutter ( 12 ) is positioned, to close the access passageway, wherein said sliding shutter ( 12 ) is fixed ( 11 ) to said longitudinal strip ( 17 ) by means of at least a hooking support rod ( 18 ), so that said sliding shutter ( 12 ) integrally entrains said strip ( 17 ) during a closing and opening movement of the passageway, said said hooking support rod ( 18 ) being constrained, by means of a sliding element ( 15 ), to a guiding rod ( 14 ) wherein closing of the sliding shutter ( 12 ) causes a lifting of an upper profile ( 1 ) of said shutter ( 12 ), said upper profile ( 1 ) thus contacting a wedge ( 2 ), which is interposed with respect to parallel elements ( 27 ) of the shaped structure ( 7 ), by means of at least one elastic element ( 4 ).
