Abstract:
A window covering has an upper rail and lift cords that extend from the upper rail to window covering material. The lift cords are wound onto respective conical spools when the window covering material is retracted and is unwound from the spools when the window covering material is extended. The conical spools move along a portion of the length of a shaft that couples the conical spools to a spring motor when the window covering material is moved from a retracted position to an extended position. The lift cords are unwound from the spools so that a segment of the lift cord that extends from the spool through a hole in the headrail is positioned adjacent a portion of the spool that has a smaller diameter when the window covering material is in the extended position as compared to when the window covering material is in the retracted position.
Abstract:
A window covering includes a roller attached to a mounting device and an actuation device attached to the roller to rotate the roller in at least one of a first direction and a second direction. A front member is attached to the mounting device. A second member is attached to the roller. A plurality of ballast members are attached to the front member. Each ballast member has a portion that extends to the second member to engage the second member to cause the front member to form substantially parallel folds when the second member is wound about the roller to retract the front member to a retracted position. Preferably, the folds are similar to or exactly like the transverse folds in shade material that are formed when a conventional Roman shade is raised.
Abstract:
A window covering may include a roller attached to a mounting device, and a front member attached to the mounting device. Strips may extend from a roller attached to the mounting device. An upper portion of each strip may be attached to the roller and a lower portion of each strip may be connected to a bottom portion of the front member. Each strip passes through a respective column of ballast members. The ballast members are connected to the front member. The columns may each be comprised of ballast members that are not more than six inches below an immediately adjacent upper ballast member when the front member is in the extended position. The spacing of the ballast members and widths of the strips cooperate to prevent any of the strips from being pulled away from the ballast members to form a loop having a diameter greater than twelve inches.
Abstract:
A cordless Roman shade includes a head rail internally provided with a tension lifting mechanism for providing a balancing force or a tension force; a shade connected at an upper portion to the head rail and including a plurality of horizontal cells; a plurality of lines associated with the shade and controlled by the tension lifting mechanism to rewind or release, so as to lift or lower the shade to a desired height; and at least one bracing system mounted on the lowest cell of the shade to stretch open and thereby stiffen the lowest cell. A user may apply an upward or downward force at the stiffened lowest cell to lift or lower the shade.
Abstract:
A foldable traverse rod includes a rod assembly and a slide assembly. The rod assembly has a first and a second rod portion connected end to end via a hinge, such that the second rod portion may be turned about the hinge to a folded position to locate on a top of the first rod portion, or to an extended position to locate in line with the first rod portion. Both of the first and the second rod portion are internally correspondingly divided into a plurality of slide channels. The slide assembly includes a plurality of link bars separately mounted in the slide channels of the rod assembly. The link bars may be sequentially pulled outward or pushed inward via a linkage system.
Abstract:
A safety buckle of a curtain comprises a curtain body and an upper beam; an auto slide-stop installed within the upper beam for controlling the curtain body to a predetermined position; and a control rope set having a first end and a second end which are at opposite sides. The first end is a rope and the second end. The safety buckle comprises a male pin having a body portion and a guide end. The body portion is positioned at a bottom of the guide end and is connected to a distal end of the rope. A female pin is firmly secured to the upper beam and has a pin seat. The pin seat is formed with a hollow guide hole. When the ropes are pulled, the male pin is separated from the female pin so that the upper beam and the ropes are in a safe state.

Abstract:
A window covering includes window covering material that extends from a first rail. A first lift cord extends from the first rail to a position adjacent the bottom of the window covering material. A first spacer cord extends from the first rail to a position adjacent to a bottom of the window covering material. First hitches extend from the first spacer cord to encircle the first lift cord. The window covering may have additional lift cords and may utilize other similar spacer cords having hitches that extend to those lift cords as well.
Abstract:
A window covering includes a plurality of cord shrouds for enclosing or covering lift cords. Each of the cord shrouds may be continuously attached to the window covering material via a continuous attachment mechanism that includes one or more columns of stitching, beads of adhesive or welding. The cord shrouds may prevent the lift cords from being pulled away from the window covering material to form loops that could pose a danger to a young child. Embodiments of the window covering may be configured as top down bottom up shades or other types of shades. The window covering material may be composed of any of a number of different materials. For example, the window covering material could include pleated material, or could be comprised of a sheet of material consisting of woven wood, interconnected fabric segments, non woven fabric or woven fabric.
Abstract:
A window covering includes a first set of lift cords extending from a headrail to middle rail. The first set of lift cords is extendable between the headrail and the middle rail to a predetermined distance, which defines a lowermost position of the middle rail relative to the headrail. The first set of lift cords is also retractable to a wound position for defining an uppermost position of the middle rail. A second set of lift cords extends from the headrail to the bottom rail and is extendable from between the middle rail and bottom rail to define an extended position of window covering material. The predetermined distance that the first set of lift cords may extend is selected to help prevent children from becoming entangled in the first set of lift cords when the middle rail is lowered away from the headrail.
