MÉCANISME DE COMMANDE POUR UN STORE À DOUBLE PAS ET ENSEMBLE DE STORES À DOUBLE PAS

摘要

A control mechanism for a double pitch blind including an array of tiltable slats (81, 82) having a first sub-array of tiltable first slats (81) and a second sub-array of tiltable second slats (82). The control mechanism includes a first spool drive (22) and a second spool drive (21), both the first spool drive and the second spool drive being configured to be rotated by a single common drive shaft (26). The first spool drive has elongate members (32a, 32b) extendable and retractable on opposite sides of the slats and the second spool drive has elongate members (34a, 34b) extendable and retractable on opposite sides of the slats. The first and second spool drives are configured to transfer rotation of the drive shaft to spool-in and so retract and to spool-out and so extend the elongate members. The first spool drive spools by a first length (L1), and the second spool drive spools by a second length (L2). The first length is larger than the second length, so that the slats are moved between open and closed states.
