Patent number: 9759009Abstract: A window covering includes a first rail; window covering material, a liner, a first lift cord, and a second lift cord. The liner is positioned adjacent to the rear side of the window covering material and is moveable from a retracted position to an extended position. The liner has at least one pocket. Each pocket defines a channel within the liner. The first and second lift cords extend from the first rail to a position adjacent to a bottom edge of the window covering material. Each lift cord extends through a channel defined by a pocket of the one or more pockets. The window covering may be a Roman shade or other window covering, such as a top down bottom up shade. Preferably, the liner covers the lift cords such that no portion of a lift cord is exposed sufficiently for a child to become entangled within any of the lift cords.Type: GrantFiled: March 9, 2010Date of Patent: September 12, 2017Assignee: Whole Space Industries LTDInventor: Tzong-Fu Lin

Patent number: 9506290Abstract: A tension device for a corded-loop drive system has a base with a sprocket on the base such that the cord loop travels over the sprocket. At least one resilient finger has a first end attached to the base and a free end. Each finger is sized and positioned to engage the cord loop when the tension device is not properly mounted to a wall or window frame and prevent movement of the cord loop around the sprocket. There is a hole in the finger through which a screw passes. When the base is placed on a mounting surface and the screw is driven into the mounting surface, the free end of the finger will have moved from the first position to a second position away from the cord so that the cord loop may move around the sprocket and the window covering can be fully raised and fully lowered.Type: GrantFiled: October 14, 2011Date of Patent: November 29, 2016Assignee: Whole Space Industries LTDInventor: Tzong-Fu Lin

Patent number: 9382753Abstract: A window covering includes a liner positioned adjacent to the rear side of window covering material. The liner is attached to at least one of the window covering material and a first rail to define at least one cavity between the window covering material and the liner. At least one ladder is attached to the liner and positioned in the at least one cavity. The at least one ladder has vertically spaced rungs. At least one lift cord extends from the first rail to a position adjacent to the bottom edge of the window covering material. The at least one cord passes adjacent to the at least one ladder such that the at least one lift cord passes over the rungs of the at least one ladder such that the at least one lift cord alternates from passing behind and in front of successive rungs.Type: GrantFiled: March 8, 2011Date of Patent: July 5, 2016Assignee: Whole Space Industries LTDInventor: Tzong-Fu Lin

Patent number: 9016347Abstract: A looped-cord system includes a beaded cord having a set of beads connected in series to form a loop with a space between each pair of adjacent beads. In one embodiment a stop sized to fit within the space between a pair of adjacent beads is attached to a housing. A resilient finger located opposite the stop pushes a portion of the beaded cord adjacent to and not engaging the sprocket against the stop so the stop is within a space between a pair of adjacent beads, thereby preventing movement of the cord loop. Applying tension to the cord loop overcomes the resilient finger and moves the cord away from the stop enabling movement of the cord loop. In another embodiment a key engages the sprocket preventing the sprocket from turning until tension is applied to the cord loop by proper installation of the tensioner on the cord loop.Type: GrantFiled: September 22, 2011Date of Patent: April 28, 2015Assignee: Whole Space Industries Ltd.Inventor: Tzong-Fu Lin

Patent number: 8684063Abstract: 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.Type: GrantFiled: November 23, 2011Date of Patent: April 1, 2014Assignee: Whole Space Industries LTDInventor: Tzong-Fu Lin

Patent number: 8561665Abstract: 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.Type: GrantFiled: September 27, 2011Date of Patent: October 22, 2013Assignee: Whole Space Industries LtdInventor: Tzong-Fu Lin

Patent number: 8544522Abstract: 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.Type: GrantFiled: October 14, 2011Date of Patent: October 1, 2013Assignee: Whole Space Industries LtdInventor: Tzong-Fu Lin

Publication number: 20130248125Abstract: 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.Type: ApplicationFiled: March 20, 2012Publication date: September 26, 2013Applicant: WHOLE SPACE INDUSTRIES LTDInventor: Tzong-Fu Lin

Patent number: 8511363Abstract: 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.Type: GrantFiled: February 13, 2012Date of Patent: August 20, 2013Assignee: Whole Space Industries Ltd.Inventor: Tzong-Fu Lin
