Rolling slat blind for use in lintel of building, has drive sprocket for rotation of orthogonal toothed axes in case of fixation of apron, and driving piece for driving toothed axes by tubular motor

摘要

The blind has a drive sprocket for rotation of orthogonal toothed axes in case of fixation of an apron. A toothed axis tube assures direct transmission of rotation between the toothed axes by an intermediary of belts. An aluminum tube prevents lateral movement of the belts. A driving piece drives the toothed axes by a tubular motor. A centering piece assures centering of the toothed axes, where the blind confirms to ISO 2000standards.
