US 7,107,126 B2 · Method of determining a shading and ventilation position for a roller band

Abstract

A method and apparatus for determining a shading and ventilation position of a a roller blind. The method including steps of identifying the final slat position in which the bottom slat is at the limit of contact with the bottom end stop of the blind, assigning to this final slat position a data defining the position, and calculating a shading and ventilation position data defining the shading and ventilation position from the data of the final slat position. The method also includes steps of storing the shading and ventilation position data in a shading and ventilation position memory. The method enabling storing of the best shading and ventilation position without necessitating the storage in memory at the site of manufacture.

A method of determining a shading and ventilation venting position (PIA) in a control system of an actuator (11) which is used to move a sun-protection, privacy or closure device (1) comprising stackable slats (2, 3) connected together by perforated parts (4), which method comprises the following steps:

identifying, by analyzing the torque exerted on the actuator (11), the final slat position (PLF) in which the bottom slat (3) is at the limit of contact with the bottom end stop of the device (1), assigning to this final slat position (PLF) a data (dPLF) defining said position, calculating a shading and ventilation position data (dPIA) defining the shading and ventilation position (PIA) from the data (dPLF) of the final slat position (PLF), and storing the shading and ventilation position data (dPIA) in a shading and ventilation position memory (13).
