| 20080245490 | ATTACHMENT OF AN ARCHITECTURAL COVERING - A system for attaching a shade material to a roller having recesses in its surface includes inserting portions of the shade material into an associated elongated recess and retaining the material in the recess with an attachment member having peaks and valleys along its length for intermittent engagement with the material within the recess. | 10-09-2008 |
| 20090236050 | WINDOW COVERING - An window covering is disclosed. The window covering comprises a first roller and a spaced apart second roller mounted in a window frame. A first sheet is connected to the first roller at its trailing edge and a second sheet is connected to the second roller at its trailing edge. Each flexible sheet is movable from a stowed position, where it is coiled around a corresponding roller to a deployed position where it is drawn away from the roller to cover the window. The rollers bias the sheets toward the stowed position. The leading edges of the sheets may be removably connectable so that, when deployed together, the sheets cover the window between the rollers and resist being pulled into the stowed position. At least a portion of the first sheet permits more light to pass through than the second sheet. | 09-24-2009 |
| 20090283224 | DUAL ROLL BLIND SYSTEM - A dual roll blind system is able to adjust a light shading degree and comprises a winding roll which includes a roll casing rotatably supported between both side plates of a ceiling bracket; a driving winding roll which includes a moving member disposed between both side plates in parallel with the winding roll and is thread-engaged with a screw shaft rotating by means of a blind winding device of one side, a straight moving member which is provided for left and right straight movements by restricting the rotation of the moving member, and a roll casing engaged with the moving member and the straight moving member; a first blind raw material of which upper end is fixed at the winding roll and in which a light transmission part and a light non-transmission part having constant widths are alternately formed in a width wise direction; a second blind raw material of which upper end is fixed at the driving winding roll and which has a light transmission part and a light non-transmission part corresponding to the first blind raw material and is movable left and right; and a counter weight bar which fixes a lower end of the first blind raw material with a lower end of the second blind raw material being slidably inserted into the counter weight bar in a parallel direction. | 11-19-2009 |
| 20120125546 | SMOKE OR FIRE BARRIER - A twin roller smoke or fire barrier having: two parallel rollers and a curtain comprised of narrow curtain portions rolled on the rollers and arranged along the length of the rollers of alternate rollers with end margins overlapping opposite each other; the barrier including: a mechanism for varying separation of the rollers by at least the change in the overall diameter of one roller and its curtain portions between wound-up and unwound states, the mechanism including: movable supported roller or rollers; whereby in the unwound state of the curtain, the overlapping margins abut or at least are separated by a negligible amount at the rollers. | 05-24-2012 |
| 20120145338 | COVER APPARATUS FOR VEHICLE - A cover apparatus for a vehicle includes: a center cover windup part including a center cover and a center windup shaft part that houses the center cover so as to be drawn therefrom and wound therearound; and side cover windup parts each including a side cover and a side windup shaft part that houses the side cover so as to be drawn therefrom and wound therearound. The center windup shaft part and the side windup shaft parts are supported with axes thereof being displaced from each other and end portions thereof overlapping each other in the axis directions thereof so that side edges of the center cover and side edges of the side covers overlap each other in the state in which center cover and the side covers are drawn. | 06-14-2012 |
| 20120193041 | Multi-Display Dual-Function Shade for Glass Window/Door - A multi-display dual-function shade includes a piece of transparency printed with multiple displaying sections and two motors to roll the transparency onto two parallel rollers. The shade acts as a variable glowing display lit by daylight and provides privacy all the time. Multiple displaying sections provide various displaying effect and allow users to choose a desired amount of daylight through the shade anytime of a day or year. The printed transparency can be detached from one roller and completely rolled up onto the other roller to leave the glass window/door uncovered when needed. The multi-display dual-function shade allows easy insertion of new displaying sections into or replacement of the existing transparency to increase the displaying capacity. An integrated multi-display dual-function shade system can be made by installing the shade between the two panes of the glass window/door. An online server system can be set up to generate the customized shade. | 08-02-2012 |
| 20120267060 | SPRING MOTOR FOR DRIVE FOR COVERINGS FOR ARCHITECTURAL OPENINGS - A covering for architectural openings. | 10-25-2012 |
| 20130020037 | WINDOW SHADE - A window shade that reduces the risk of an individual becoming entangled in cords used to operate the shade includes a headrail adapted for horizontal mounting above a window, a shading material attached to the headrail, and at least one cord for raising and lowering the shading material. The cord is attached to a location adjacent a lower end of the material, and extends upward through cord guides toward the headrail. The cord is encased within a collapsible shroud attached to each cord guide. The shroud is adapted to longitudinally extend as the shading material is lowered toward a deployed position, and then longitudinally collapse as the shading material is raised toward a stowed position. The cord is secured to and is wound about a spool fixed to a spring-loaded roller. The roller provides tension on the cord that counterbalances the weight of the shade so that the shading material may be positioned at any desired level. The shade does not require a graspable cord or cords for operation. | 01-24-2013 |
| 20150068690 | ADJUSTABLE WINDOW COVERING SYSTEM - An adjustable window covering system for substantially or partially covering a window to block light, provide privacy, reduce heating/air conditioning costs, reduce installation costs, or change the aesthetic appeal of the window or the area around the window is disclosed. A user can dynamically adjust the configuration, location, position, and material layer of the adjustable window covering system without the use of tools and without damage done to the walls of a window. | 03-12-2015 |
| 20150376941 | COVERING FOR AN ARCHITECTURAL OPENING - A covering for an architectural opening is provided. The covering may include a head rail, a first roller rotatably supported by the head rail, a second roller rotatably supported by the head rail, a first shade attached to the first roller, and a second shade attached to the second roller. The second roller may be positioned rearward of the first roller. The first shade may be wrappable about the first roller. The first shade may include two laterally-separable sheets interconnected by a plurality of vertically-spaced vanes. The second shade may be wrappable about the second roller. | 12-31-2015 |
| 20160053536 | DOOR, IN PARTICULAR VERTICAL-LIFT DOOR, FOR CLOSING AN OPENING IN A WALL WHICH SEPARATES TWO DIFFERENT TEMPERATURE ZONES FROM ONE ANOTHER - A door, in particular vertical-lift door, for closing an opening in a wall, in particular in a wall which separates two different temperature zones from one another, having a movable, flexible door leaf which comprises multiple separate, flexible door leaf layers which are guided such that they are spaced apart from one another in the closed state of the door, and having at least one winding shaft onto which the door leaf can be wound up in order to open the door, in which two adjacent door leaf layers are connected to one another by at least one spacer which ensures a spacing, defined by the spacer, of the two door leaf layers at least in the region of the spacer in the closed state of the door. | 02-25-2016 |
