Abstract: The present invention relates to a self-raising window covering and a control mechanism for the window covering. In particular, the window covering includes a drive unit, such as constant force spring, that is adapted to apply a substantially constant rotational force on the drive axle. A cord winding assembly is coaxially mounted on the drive axle, and includes at least one winding drum operatively connected to a second end of the raising cord and having a tapered portion, as well as a rotatable positioning member for moving the cord winding assembly laterally along the drive axle upon rotation of the positioning member. The cord winding assembly is adapted to translate the rotational force on the drive axle to a raising force on the raising cord, wherein the raising force is greater than a downward force exerted by the shade element and bottom rail throughout the range of opening and closing.

Abstract: A window covering having a head rail and a plurality of rows suspended from the head rail by a securement cord member and at least one opening cord member is provided. Each of the plurality of rows is collapsible and includes a pair of opposed longitudinal regions. The distance between the opposed longitudinal regions is varied by moving the securement cord member, the opening cord member, or both. The rows are also tilted into an open or closed position by moving the securement cord member, the opening cord member, or both. A bottom rail may also be provided and suspended from the head rail such that the plurality of rows are located between the head rail and the bottom rail.

Abstract: A cellular structure such as a honeycomb window treatment comprises a plurality of rows of elongated cells secured to one another. Each of the rows is constructed by providing a first longitudinally extending length of material, which includes a first surface and a second surface, as well as, a lesser width portion and a greater width portion. A second length of material is also provided that includes a first surface and a second surface of the first material. The second surface of the second material is secured to the first surface over the greater width portion of the first material along a plurality longitudinally extending locations on the second surface of the second material to form a row. A longitudinally extending crease is also formed in the first material such that the lesser width portion and the greater width portion of the first material lie on opposite sides of the crease.

Abstract: An adjustable shade rail for use with a window covering and method of making the shade rail is provided by combining a first and second rail element. The width of the adjustable shade rail can be adjusted by varying the position of the first rail element in relation to the second rail element.

Abstract: A fastener module and fabric panel suitable for use with a window covering having a plurality of openable rows is provided. More particularly, the fastener module enables engagement and disengagement of control cords from panels of a window covering.

Abstract: The present invention relates to a window shade or a window covering having a control mechanism for raising and lowering the window covering. The control mechanism is provided with a separator system. In particular, the present invention relates to a control mechanism with a separator system that provides a disengagement function to prevent or minimize damage to the control mechanism as a result of unintended force on the window shade or window covering. The separator system utilizes a body movable between a mated position where a clutch axle and a winding axle move synchronously, and an unmated position where the winding axle is allowed to rotate independent of the clutch axle.

Abstract: A suspension system for a window covering that eliminates the use of pull cords is provided. The suspension system includes a control module having a winding drum and a spring disposed about an axle. A friction member or reaction member is also provided to offset difference in the force exerted by the spring on a suspension cord versus the weight of the window covering member.

Abstract: Cellular panels may be suspended from head rails through the use of a rigid strip of material positioned with the cellular panel. In order to securely position the rigid strip and cellular panel with respect to the head rail, a securement insert is provided. The securement insert includes a cap securable with the head rail by an interference fit and a slot member including a restricting member extending from the cap.

Abstract: A window covering having a plurality of panels comprising a head rail and a plurality of panels suspended from the head rail by a securement member and at least one opening member is provided. Each of the plurality of panels is collapsible and includes a pair of opposed longitudinal regions. A bottom rail may also be provided and suspended from the head rail such that the plurality of panels are located between the head rail and the bottom rail.

Abstract: An improved cutter for minimizing deflection of the scissor blades during the cutting of a rigid slat, in particular the slats of a Venetian blind. The cutter includes a first scissor and a second scissor pivotally joined to each other at a fulcrum. The scissors further include blade portions suitable for cutting a slat when the scissors are closed. An engagement member is located at the distal end of each scissor. The engagement members are adapted to cooperatively engage one another as the jaw members are closing so that the engagement member of the second scissor is on top of the engagement member of the first scissor.

Abstract: A cordless window covering having a differential suspension mechanism. The suspension mechanism is composed of a first rotary drum for winding and unwinding the suspension cord of a window covering and a second rotary drum housing a spring with one end connected to the second rotary drum and the other end of the spring connected to an axle. Rotation of the first rotary drum and at least one end of the spring are linked by a transmission system. In operation, the transmission system creates a differential rotation rate between the first rotary drum and the relative rotation rate of the two ends of the spring. In this manner, a greater length of cord can be deployed for with a shorter length of spring extension.

A bottom rail may also be provided and suspended from the head rail such that the plurality of panels are located between the head rail and the bottom rail.

Abstract: A cutting machine for window shades comprising a head rail, a bottom rail, and a plurality of light blocking sections. The cutting machine comprises a body with a platform for supporting the window shade, a clamp mechanism for securing the window shade, a blade rotationally connected to the body for cutting the window shade, and an actuating mechanism. The actuating mechanism is operatively connected to the blade, causing the blade to move in a rotational movement for cutting the secured window shade.

Abstract: A suspension cord control mechanism composed of an arresting mechanism and a biasing mechanism operable to move a light blocking element after the user has released a suspension cord. The biasing mechanism is loaded when the suspension cord is drawn by a user to lift the window covering. When the suspension cord is released, movement of the cord is stopped by the arresting mechanism and the biasing mechanism unloads to further move the light blocking element.

Abstract: A window covering including a plurality of panels vertically suspended from a vertical securement member is provided. The plurality of panels is secured with the securement member about an upper transverse portion of the panels at spaced intervals along the securement member. The closure rows are convertible between different configurations by detaching the lower transverse portions of the closure rows from the suspension members.
