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.

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: 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.

Abstract: A system for customizing lengths of fabric material for constructing rows of a window covering. The system includes a container box supported by a substrate and a cutter for trimming desired lengths of material from a roll of material.

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 longitudinal portion of the panels at spaced intervals along the securement member. The panels are freely suspended or dangle from the securement member such that a lower longitudinal portion of the panels is not connected with the securement member or the opening member. A weighted edge member may be included about the lower longitudinal portion of the panels. The window covering is opened by adjusting the opening member to rearwardly and vertically stack the plurality of panels.

Abstract: A control mechanism for use in a window covering to control the raising and lowering of one or more control cords to open and close light blocking elements is provided. The control mechanism includes a frame which is mountable within a support structure, such as the headrail, and includes as a first abutment stop and a second abutment stop. The position of the frame of the control mechanism is slidingly adjustable relative to the head rail to accommodate different width window spaces.

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 customizable width panel and anchor member for a window covering. The panel is customizable in width and preferably comprises a plurality of spaced openings along a longitudinal portion thereof. The anchor member, which is restrainedly positionable with a control member has a selectable width and is restrainedly positioned with the longitudinal portion of the panel.

Abstract: A fastener module 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: A window shade comprising a plurality of collapsible shade rows. Each of the shade rows being adjustable from a closed state to an opened state by an operating mechanism, and including a stiff first transverse region and an opposed second transverse region having a stiffened edge portion. When in the closed state, the window covering includes no or minimal gaps between the rows so that light is substantially or completely blocked. Also, the securement and opening members are also concealed from view when observed from the front or face of the window covering. The operating mechanism causes the narrowing of the rows by drawing the first transverse region and the opposed second transverse region closer together. The operating mechanism further causes the rows to be pivotally rotated to further widen opening in the window covering.
