摘要:
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.
摘要:
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.
摘要:
An apparatus and method for making expandable honeycomb structures suitable for use as window coverings is provided. Material is fed to a folder and past a cutter. Adhesive is applied to the material downstream of the cutter and the material is cut to desired lengths. The cut strips of material are stacked with similarly formed strips to form the honeycomb structure.
摘要:
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. A sliding module is mounted with the frame and is also secured with the control cord. The first abutment stop limits or arrests the movement of the sliding module at a first position, and the second abutment stop maintains the sliding module at a second position.
摘要:
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.
摘要:
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.

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. A clutch member or locking member is also operatively connected with the axle and adapted to releasably lock the drive axle in a desired position.
