Hinged-slatted venetian draw-blind - with bottom slat angled when lowered for progressive angled overlap on raising

摘要

The blind has slats (1) interconnected by hinge joints, and a draw organ (5) engaging an end rail (2). There is a slide element on the slats acting in conjunction with a guideway on an adjacent slat extending over the slat width, and levers able to effect an inclined setting of the bottom slat, when the blind is lowered. When the blind is drawn up the slats are progressively and correspondingly inclined upwards, one thrusting above the other in the fashion of roof tiles. The inclined setting of the bottom slat may be effected by a triangular-sectioned end rail, the sloping surface of which serves as support for this slat when the blind is raised.
