Abstract: Manual deployment apparatus for specialty, pleated or multi-cellular window covering treatments including uniquely hinged mounting rails and single and/or continuous strand pull cords. The invention consists of apparatus that is used to acquire two modes of pleated or multi-cellular shade fabric deployment over generally curvillinear window openings, but particularly over window openings having circular and segmented shapes. A translational deployment, known as the "Blossom Mode" moves a sculptured shade from its rest position by actuation of a continuous cord that is under constant tension. The shade may be deployed to any extent from the mere movement from the completely stowed position to the fully extended. The second modality, known as the "Fan Mode" contemplates deployment of the multi-cellular shade by commencing with the stowed shade marginally secured between a pair of superimposed, and hingably connected rails.

Abstract: A motorized blind assembly has top and bottom horizontal end members and a horizontal intermediate blind base member displaceable between the top and bottom members. The ends of a foldable and extensible accordion-like blind are secured, respectively, to the top end member and to the blind base member. An idle pulley is mounted on the bottom end member while a blind drive mechanism is mounted on the top end member; the latter mechanism including a drive friction pulley and a motor assembly able to drive the drive pulley in either of the two directions of rotation. An operating belt winds around the drive and idle pulleys and a mechanism connects the ends of the belt to the base member, this latter mechanism being conceived so that, when the motor assembly is energized, the blind base member moves between the end members causing the blind to fold and unfold. The ends of the belt may alternatively be secured directly to the blind base member.

Abstract: A pleated fabric is connected between an upper fixed sill and a movable sill. The movable sill is between the upper fixed sill and a lower fixed sill. Two string loops are resiliently secured to the sills and slidably frictionally engaged with the movable sill symmetrical relative to the sills and to a central axis parallel to the direction of movement of the movable sill. The tension in the strings is adjustably set by a single tension spring and a turnbuckle connected between and to the loops. The friction engagement of the strings to the movable sill is set to a friction load having a value which provides smooth operation and tends to keep the movable sill in place at whatever location the sill is moved to regardless the blind orientation relative to gravity.

Abstract: This invention is an improvement over my U.S. Pat. No. 4,326,577 for a window screen arrangement comprising a novel roller combination for winding and unwinding the screen or shade element and at the same time positioning of the entire screen assembly in a desired position vertically on a window to provide partial screening in any part of the window while at the same time permitting additional screening provided by the operation of the screen upon a roller. The method of supporting the screen in the window opening comprises a novel arrangement of cords for support and positioning which permit the foregoing without the use of pulleys, springs, counter-weights, hooks, clamps or other positioning devices to hold the screen assembly in any given location by permitting its roller features to function.

Abstract: A sun blind suitable for installation in, for example, window openings, including window openings having an inclination from the vertical, is disclosed. The sun blind comprises a first bar disposed at the top of the window opening, a second bar movable with respect to the first bar, a foldable sun blinding member attached between the first and second bars and a third bar disposed at the bottom of the window opening. A first cord arrangement is used to move the second bar and thus the sun blinding member. A second cord arrangement is used to guide the second bar and the sun blinding member. A suitable tension means, such as a spring, preferably located in the third bar, applies tension to the second cord arrangement so as to keep the cords of the second cord arrangement taut and thus properly guide the sun blinding member and the second bar with respect to the inclination of the window opening.
