Abstract (en)
A fast-sliding roll up door comprises a flexible curtain (12) adapted to close an opening defined by an upper crosspiece (14) and a base plane (16), and by a pair of longitudinal uprights (18). The upper edge (12a) of the curtain (12) is connected to a winding shaft (20) driven in rotation by control means that control the vertical movement of the curtain (12), which include a transmission roller (24) parallel to the winding shaft (20), whose outer surface is engaged by a portion of the curtain (12). The rotation of the roller (24) is controlled by driving means that include a first pair of gear wheels (28) coupled to the ends of the roller (24), and a second pair of rotatable gear wheels (38) adjacent to the base plane (16). Such gear wheels (28, 38) are engaged by flexible drive members (32, 36) each of which supports a side dragging member (40) for dragging the curtain (12). Counterweight means (42, 44) connected to said winding shaft (20) controls the rotation thereof.
