Fast mode roller shutter, has flexible plastic components protruding at surface of door leaf in closing condition and dimensioned with respect to their dimensions such that components keep positions of leaf on distance

摘要

The shutter has a door leaf (3) formed from panels (2) that are connected with each other in a flexible manner. A frame (4) guides the leaf and a roll shaft (5), where the leaf is wound on the shaft in number of positions. The cross sectional profile of the panels has central, upper and lower connection sections, where the upper section is engaged into the lower section. Flexible plastic components (7) protrude at the surface of the door leaf in a closing condition and are dimensioned with respect to their dimensions such that the components keep the positions of the leaf on a distance.
