摘要

The device (40) has strings (5) connected to a blind and a support (41) for rolling spool (42). The support is formed by lower and upper parts (41a, 41b) fabricated by the assembly of passage holes (48) to slide strands of the strings. The lower part is attached to different types of rails and upper part is linked to the spool. The upper and lower parts are assembled by non-permanent links.
