Abstract

The blind strips are moved sideways by means of a threaded shaft running through the carriage. The shaft has a nut with internal thread corresponding to that of the shaft. A drive spindle has a pinion attached to it connected to a second pinion on a second shaft. The drive spindle has a nut with cogging round the outside and an internal thread corresponding to that of the drive spindle. The axial movement of the nut is limited by two stop pieces. The nut is connected to a third pinion. The drive spindle has a coupling on one end which grips into holes in a sprocket wheel, pivot mounted on the pivot pin of a wall bearing. The sprocket wheel can be turned in both directions by a pulley chain which turns the drive spindle.
