The drivers (12,13) are rigidly connected (11) by means of a crossbar (14) which integrates the two drivers and is releasably joined to these. The width of the assembly (2) and/or the spacing between the rope sectors (3,5) and that between the drives (12,13) and slides is less than half the width of the window. An additional driver can be fixed to the rope sectors and drives and slides ride in a guide (6) on the assembly piece (2), the guide (6) either integrated with the second guide or again screwed, riveted or welded to the assembly as an independent component. The rope ends are hinged by adjusters to the connection (11) and crossbar, using rollers at all four corners of the assembly piece frame to give a single rope four-roller system. |
