| 20110297334 | SPRING SYSTEM FOR ROLLER BLINDS - A roller blind including a roller of having a roller length and a roller outer diameter, a fabric attached to said roller for winding and unwinding from said roller. The fabric has a fabric length, a fabric weight, a fabric height, and fabric thickness. The blind includes a bottom bar having a bottom bar weight, and at least one spring operatively connected to the roller to drivingly rotate the roller in at least one direction of rotation. The spring is selected according to a Protocol such that it's length ensures that it drives the roller with a constant operating force. | 12-08-2011 |
| 20110041407 | LOUVER ROTATING MECHANISM - A louver rotating mechanism for louvers of a sectional covering for architectural openings is adapted to rotate the louvers between an open position and a closed position. In the open position, the louvers are in generally parallel planes, and in the closed position, the louvers are generally in a common plane. The rotating mechanism includes a slot and gate system. | 02-24-2011 |
| 20100288451 | OPERATING UNIT FOR ARCHITECTURAL COVERINGS - The invention relates to an operating unit ( | 11-18-2010 |
| 20100236730 | Roller blind mounting system and parts therefor - A roller blind mounting system including at least one roller, at least one telescopic end plug and at least two brackets. The telescopic end plug is engageable within an end-opening of one of said rollers. The end plug includes a hollow body and a telescopically movable member or plunger co-axially positionable with respect to the hollow body such that a first axial extending length portion of the plunger projects from the hollow body and a second axial extending length portion is held within the hollow body. The plunger is telescopically movable between a first end position in which the first portion of the plunger projects from the cylindrical body and a second end position in which at least part of the first portion is inserted into the cylindrical body. | 09-23-2010 |
| 20100212843 | COVERING FOR AN ARCHITECTURAL OPENING - The present invention relates to end stops for use in retractable coverings for architectural openings where the end stops have impact-absorbing means which are bi-directionally cushioning. The end stop will remain at a dedicated position even after being impacted. | 08-26-2010 |
| 20100101741 | OPERATING SYSTEM FOR AN ARCHITECTURAL COVERING - Operating system ( | 04-29-2010 |
| 20090258752 | OPERATING AND MOUNTING SYSTEM FOR A WINDOW COVERING - An operating unit ( | 10-15-2009 |
| 20090199977 | COVERING AND COMPONENT PARTS THEREOF - An architectural covering arrangement having two side rails for mounting in parallel either side of a window pane and at least one movable end rail for mounting perpendicular to the side rails and extending from one side rail to the other side rail, the side rails having on respective faces to be mounted on a window pane, a two-layer fastening structure with one of the layers adhered to the respective side rail and the other of the two layers to be adhered to the window pane, the two layers being freely attachable and detachable from one another. | 08-13-2009 |
| 20090057512 | BRACKET FOR MOUNTING A GUIDING RAIL - Bracket for mounting a guiding rail to a support surface. The mounting bracket includes a body part having a main body defining a mounting hole and opposite parallel first and second snap flanges. The bracket further has a clip part for engaging its body part and has at least one resilient tongue and at least one resilient arm extending from the clip part in alignment with the first and second snap flanges. The invention also relates to the combination of the mounting bracket and a guiding rail, as well as to a method for mounting a plurality of the brackets and the guiding rail to a mounting surface. | 03-05-2009 |
| 20090056885 | HEAD RAIL ASSEMBLY - A head rail or head rail assembly for an architectural closure, the head rail including an elongate front wall having left hand and right hand longitudinal ends and an elongate bottom wall having left hand and right hand longitudinal ends. A left hand end structure is positioned adjacent to the left hand longitudinal end of the bottom wall and a right hand end structure is positioned adjacent to the right hand longitudinal end of the bottom wall. A first slot is defined between the left hand end structure and the left hand longitudinal end of the bottom wall and a second slot is defined between the right hand end structure and the right hand longitudinal end of the bottom wall. At least one of the first and second slots is closed by a removable closure. | 03-05-2009 |
| 20090056269 | ANCHORING DEVICE - The invention provides an anchoring device for anchoring an elongate guide element of an architectural covering. The anchoring device includes a body having a rear surface. The body is suitable for attachment to a support structure with the rear surface in close contact with the support structure. The body includes a receiving cavity for receiving the elongate guide element, a first entrance to the receiving cavity and a second entrance to the receiving cavity. The receiving cavity can receive the elongate guide element selectively either through the first entrance, with the rear surface having a first orientation with respect to the elongate guide element, or through the second entrance, with the rear surface having a second orientation with respect to the elongate guide element, and wherein the second orientation is substantially different from the first orientation. | 03-05-2009 |
| 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 |
| 20080210390 | CONTROLLING A POSITION OF A FLEXIBLE COVERING - A control apparatus for positioning and counterbalancing an amount of flexible blind material wound onto or unwound from a rotatable shaft of a windable covering such as a blind. The apparatus includes a main body and a variable torque device, at least partially fitted within the main body, having means of achieving a variable torque to prevent rotation of the shaft due to a variable weight of blind material hanging from the shaft in any position between a wound position and an unwound position of the blind material defining full travel of the windable covering. | 09-04-2008 |
