Inclined shutter has flexible connectors on one side fixed at certain points in end regions of successive shingles to define maximum spacing to improve stability

摘要

the inclined shutter has an inclined winding shaft (14) and inclined shingles (26,28) in side guide rails. Flexible connector elements (32) on at least one side are fixed at certain points (46) in the end regions of successive shingles to define a maximum distance between these fixing points in operation. The connector elements can be provided on the lower side of the installation between the shingles to extend over the entire width.
