The hollow bars (9) connected to one another in an articulated manner are guided in side grooves (7) and over a drivable lifting shaft (6). The lifting shaft (6) is mounted at both ends in a carrier (4a and 4b, respectively) which are provided with a guide groove (8). A guide divided up by a deflection wedge (11) into two separate branches (11a, 11b) reaching to a support (13) at the lower carrier end is provided only on one (4a) of these carriers. Guide bolts arranged only at the relevant end of every second bar (9) interact with the guide which is present only on one side, the end pins (12b), offset alternately, of said guide bolts folding the armouring behind the lifting shaft (6) by the action of the deflection wedge (11). In order to be able to keep the bars on the other roller-shutter side, in addition, in the correct position during and after folding, there are provided on the carriers (4a, 4b), on the front and rear sides, guide ribs (14) which extend over the entire height of the storage space and serve at the same time as catch-locking tongues for the removable support channel (13). …<IMAGE>… |
