Abstract
A set of window covering panels may be raised or lowered from a header mounted upon the window casing. Pull cords and drop cords on the panels permit the panels to be raised and lowered one at a time or all at a time. Guide members keep the panels in vertical alignment and cam surfaces permit one panel to slide up behind the next higher panel when shifting the panels into a nested condition.
Claims7
A set of panels for providing a window covering or blinds comprising,
- a header member serving to mount the panel set with respect to a window opening on the inside window frame;
- the panels in the set each comprising a generally rectilinear, substantially rigid frame and a fabric-like material mounted upon the frame serving to provide a light occluding effect or a selected aesthetic effect,
- the panel frame including upper and lower frame bars and a pair of spaced apart side rails connected to the frame bars,
- vertical guide means arranged on each panel extending along the side rails serving to guide consecutive panels in the set into an overlying, juxtaposed condition when the set is arranged in a minimally light occluding position as well as to guide consecutive panels into a deployed, aligned generally planar, contiguous position when the set of panels is disposed in a maximally light occluding position,
- said guide means including an elongate, stationary portion on one panel cooperable with a slider member carried by an adjacent panel movable along the elongate portion as the panels in the set are raised or lowered with respect to each other, and
- guide surfaces on the upper and lower frame bars on panels consecutive in the set serving to promote sliding a lower panel onto one side of the next adjacent panel and into an overlying position so that all panels in the set may nest together into an area of vertical plane not substantially larger than the area of a typical panel,
- the guide surfaces being generally complimentary, confronting, substantially beveled surfaces on adjacent frame bars,
- and a cord system connected to the panel set for raising and lowering the panel set with respect to the header member.

- said guide means including an elongate slot extending substantially the length of the guide rail on one panel co-operable with a slider member carried by an adjacent panel movable along the elongate slot as the panels in the set are raised or lowered with respect to each other, said slider member being configured and arranged in the slot for sliding action therealong, and
