Opening e.g. inclined atrium window, closure device e.g. blind, for curved frontage, has sliders with length lower or equal to sum of width of leafs such that shutter presents zigzag or rectilinear form at deployed state

摘要

The device has an accordion-pleated shutter (1) formed of a succession of motorized leafs (2) articulated one with respect to another by articulation units i.e. hinges (3). Transversal edges of one leaf have supporting and guiding elements (4) i.e. rubbles, that are respectively guided by curved parallel sliders (5). The sliders are constituted of lateral posts (7) or parallel lower or upper cross pieces (12) of a peripheral frame (6). The sliders have a length lower or equal to the sum of the width of the leaves such that the shutter presents a zigzag or rectilinear form at a deployed state.
