Abstract
A venetian type blind has a bottomrail, a headrail positioned above the bottomrail, a pivot slat positioned between the headrail and the bottomrail and a tilt slat located immediately below the pivot slat. A set of upper ladders extends from the headrail to the pivot slat and carries a set of upper slats. A set of lower ladders extends from the bottomrail to the tilt slat with each lower ladder being connected to a pivot member on the pivot slat. The lower ladders carry a set of lower slats. At least one pivot cord connects the pivot slat to the tilt slat. This arrangement allows the lower slats to be separately tilted to a different position from the upper slats.
Claims15
A venetian type blind comprising:
- a. a bottomrail;
- b. a headrail positioned above the bottomrail;
- c. a pivot slat positioned between the headrail and the bottomrail, the pivot slat comprised of:
- i. an elongated pivot slat body having a front edge and a rear edge;
- ii. a plurality of upper ladder connectors attached to the elongated pivot slat body the connectors positioned and configured to receive an upper ladder front rail adjacent the front edge of the elongated pivot slat body and an upper ladder rear rail adjacent the rear edge of the elongated pivot slat body;
- and
- iii. a plurality of lower ladder tilt members each tilt member connected to the elongated pivot slat body and positioned below the elongated pivot slat body and between the front edge and the rear edge of the elongated pivot slat body;
- d. a plurality of upper ladders each upper ladder having a front rail and a rear rail and extending from the headrail, each rail of an upper ladder attached to an upper ladder connector;
- e. a tilt slat positioned immediately below the pivot slat, the tilt slat comprised of:
- i. an elongated tilt slat body having a front edge and a rear edge;
- ii. a plurality of lower ladder connectors attached to the elongated tilt slat body the connectors positioned and configured to receive a lower ladder front rail adjacent the front edge of the elongated tilt slat body and a lower ladder rear rail adjacent the rear edge of the elongated tilt slat body;
- f. at least one pivot cord running from each lower ladder connector to a said lower ladder tilt member;
- g. a plurality of lower ladders extending from the bottomrail toward the headrail each lower ladder attached to a lower ladder connector,
- h. a plurality of upper slats carried on the upper ladders
- i. a plurality of lower slats carried on the lower ladders;
- j. at least two lift cords each having a terminal end attached to the bottomrail, running past the lower slats and the upper slats and passing into the headrail;
- and
- k. wherein rotation of the tilt slat causes corresponding rotation of the bottom rail.
