Abstract
A quick-action rolling shutter door and to modules thereof. Quick-action rolling shutter doors are used for closing openings in tie walls of warehouses or factory buildings in order to restrict the loss of energy from heated or cooled rooms, and to protect the environment by keeping escaping noise, odours and dust emissions to a minimum. Known quick-action rolling shutter doors have disadvantages in relation to heat insulation. The object is to provide an improved quick-action rolling shutter door with corresponding modules. According to a first aspect, a flexible quick-action rolling shutter door hanging (12) can be wound up onto a roller, is guided on at least one side by a guiding device and has at least one thick-walled insulating layer (36, 38) consisting of plastic foam material.
Claims9
A quick-action rolling shutter door hanging including a crash protection device, in which the quick-action rolling shutter door hanging (12) may be slid in the vertical direction along a guide rail (26) of a guiding device (14), the crash protection device comprising at least one guide part holding a bottom portion of said quick-action rolling shutter door hanging, said guide part including an upper sliding body as well as a lower sliding body connected thereto via a vertical coupling belt (110), said upper sliding body directly engaging said quick-action rolling shutter door hanging (12), and wherein said bottom sliding body engages a coupling (96) which in turn engages said quick-action rolling shutter door hanging (12), wherein said coupling (96) includes a first coupling part (98) on the side of the rail and a second coupling part (102) on the side of the hanging, which parts can be decoupled under the influence of a force acting transversely to the direction of travel of said door hanging.
