Abstract
An improved venetian type blind has slats having at least one small hole adjacent one edge of each slat. At least two ladders having opposing cord type rails and rungs extending therebetween carry slats and are connected to the bottomrail. A first lift cord runs through the holes and adjacent to the first ladder. A second lift cord runs across the opposite edge of each slat adjacent the rail of a second ladder. A similar arrangement can be provided using pairs of spaced apart holes and two pairs of lift cords. A tilt mechanism attached to the headrail moves the oppositely disposed lift cords and the rails of the ladders together when the blind is changed from an open to closed position.
Claims27
A venetian type blind comprising:
- a bottomrail;
- a plurality of slats above the bottomrail, each slat having a first edge and a second edge parallel to the first edge and a hole near the first edge so that each hole is at least partially obscured by an adjacent slat when the slats are in at least one of two closed positions;
- a first ladder connected to the bottomrail and having opposite rails and rungs extending therebetween, one rail of the first ladder positioned adjacent the first edge near the hole in each slat and the second rail positioned adjacent the second edge of the slats;
- a first lift cord connected to the bottomrail, the first lift cord running through the hole in each slat;
- a second ladder connected to the bottomrail and having opposite rails and rungs extending therebetween, one rail of the second ladder positioned adjacent the first edge and the second rail positioned adjacent the second edge of the slats;
- at least one second lift cord connected to the bottomrail and running adjacent the second edge of the slats and adjacent the second rail of one of the ladders the second lift cord being engaged with at least some of the rungs of that ladder;
- a headrail above the bottomrail and the plurality of slats through which the lift cords pass;
- and
- a tilt mechanism attached to the headrail and to which the first and second ladders are attached.

A venetian type blind comprising:
- a bottomrail;
- a headrail above the bottomrail;
- a plurality of slats between the headrail and the bottomrail, each slat having a first edge and a second edge parallel to the first edge and a hole near the first edge so that each hole is at least partially obscured by an adjacent slat when the slats are in at least one of two closed positions;
- a first ladder having opposite rails and rungs extending therebetween, the first ladder carrying the slats, positioned near the hole in each slat and connected to the bottomrail;
- a first lift cord running through the hole in each slat and adjacent the first ladder, there being no other lift cord adjacent the first ladder;
- a second ladder having opposite rails and rungs extending therebetween, the second ladder carrying the slats, spaced apart from the first ladder and connected to the bottomrail;
- a third ladder having opposite rails and rungs extending therebetween, the third ladder carrying the slats, spaced apart from the first ladder and connected to the bottomrail;
- a second lift cord passing from the headrail along the second edge of the slats adjacent to one rail of the second ladder and engaging at least some of the rungs of the second ladder, through the bottomrail along the second edge of the slats adjacent one rail of the third ladder and engaging at least some of the rungs of the third ladder, and into the headrail;
- and
- a tilt mechanism attached to the headrail to which tilt mechanism at least the first, second and third ladders are attached.
