ROLLO MIT EINEM VORBESTIMMTEN WINKELGESCHWINDIGKEITSVERLAUF

摘要

The roller blind (3) consists of a foil with horizontal reinforcing ribs (5) at regular intervals. Each rib defines space sharp 90 degrees bend in the foil, and the section in between is gently curved. There is a bar (4) at the bottom of the foil. The foil is wound up on a roller (2) which is shaped as an isosceles triangle. The roller shaft (1) is driven by a motor (M) driving through a reduction gear (R) with non-circular gear wheels (1-6).
