Abstract:
An actuator device is provided for use in a view-through window covering having a plurality of cells. The actuator device includes at least one cooperating pair of control members including a first control member that engages an upper portion of each cell and a second control member that engages a lower portion of each cell. The cooperating pair of control members are engaged with the cells along a plane parallel to the plane of the window covering, whereby relative movement of the control members modifies the size of the space between the cells. A cell and method of manufacturing a cell for a multi-cell window covering is also disclosed. The method includes the steps of providing a flexible material, stiffening a portion of the flexible material, and creating at least one control engagement formation and at least one control clearance formation in axially extending sections of the stiffened flexible material that will become an upper portion and a lower portion of the cell. The method is further defined by folding the flexible material to create a closed element and securing the flexible material to itself to maintain the shape of the closed element.
Abstract:
A window covering includes at least one pair of cell-supporting cords comprising a first support cord supporting an upper portion of each cell and a second support cord supporting a lower portion of each cell. The collapse and expansion of each cell is accomplished by the respective raising and lowering of the second support cord without movement of the first support cord.
Abstract:
A window covering is described having a carrier grid and a plurality of horizontal strips of fabric secured to the carrier grid. The strips are disposed in overlapping and vertically spaced relation to cover an area of a window.
Abstract:
An actuator device (12) is provided for use in a view-through window covering (10) having a plurality of cells (14). The actuator device (12) includes at least one cooperating pair of control members including a first control member (16) that engages an upper portion of each cell (14) and a second control member (18) that engages a lower portion of each cell (14). The cooperating pair of control members are engaged with the cells (14) along a plane parallel to the plane of the window covering, whereby relative movement of the control members modifies the size of the space between the cells. A cell (14) and method of manufacturing a cell for a multi-cell window covering (10) is also disclosed. The method includes the steps of providing a flexible material, stiffening a portion of the flexible material (76), and creating at least one control engagement formation and at least one control clearance formation in axially extending sections of the stiffened flexible material (76) that will become an upper portion and a lower portion of the cell (14). The method is further defined by folding the flexible material to create a closed element and securing the flexible material (76) to itself to maintain the shape of the closed element.
Abstract:
A window shade (60) having a power actuation system. The window shade includes a fixed member (63); a rotatable member (62) that is rotatable relative to the fixed member; a reversible motor (64) mounted to the fixed member, wherein the reversible motor includes a mechanism for driving the rotatable member such that rotation of the reversible motor in a first direction deploys a shade material and rotation of the reversible motor in a second direction stows the shade material; and a control circuit (66) coupled to a set of motor leads of the reversible motor, wherein the control circuit switches the reversible motor among at least three operational states, including: a hold state in which the motor leads are shorted to resist rotation, a deploy state in which the motor leads are connected to a power source to deploy the shade material, and a stow state in which the motor leads are connected in reverse to the power source to stow the shade material.
