Abstract
Description
- The invention relates to a multi functional roller blind for an architectural opening, such as a window, the blind having multiple shade members with distinct characteristics.
- Various multi functional coverings for architectural openings have been proposed in the past, for example having two shade members one of the shades which will be translucent and the other being able to block light. Or one of the shades provides significant thermal insulation while other is translucent. One of the shades may even be an insect screen. Some of such window coverings are known as so-called night&day shades. The purpose of this type of window covering being that the user can select and operate one of the shade members upon his needs to cover his window.
- Different types of multi-functional roller blinds have also been proposed in the art. Such as a multi functional roller blind having a single sheet of fabric having sections with different characteristics which sheet can be spooled between a pair of rollers. By spooling the one sheet different sections can be selected. This is e.g. disclosed by
DE102007028286 . This type of roller blind has as drawback that it is not possible to select and operate the sheet to be used. - Another multi-functional roller blind is disclosed in
US 7093643 and this one uses pair of roller blinds one in front of the other. Each of these blinds can be used independent from the other. Although this multi functional roller blind makes it possible to select and use the sheet to be used, it needs double the space to install as for a single roller blind. Such space is often not available. - It is therefore an object of the invention to propose a multi-functional roller blind covering for an architectural opening combining the advantages of both needing little space for mounting and of the possibility of selecting and using each shade member.
- These and other objects of the invention are achieved by providing a multi functional roller blind for an architectural opening such as a window having at least two parallel first and second roller blind units provided with first and second shade members respectively and a parallel profile,
the first roller blind unit is between the profile and the second roller blind unit, and the first shade member is attached by a free end to the profile and the second shade member is attached by a free end to the first roller blind unit but not retractable into that first unit, and movement of the first or second units respectively extends or retracts the first and/or second shade member,
and first and second tension cord arrangements are routed through the respective first and second roller blind units such that each tension cord arrangement prevents the unit through which it is routed from moving on its own accord. - Thus this blind can be mounted in the same space as would be available for a single roller, and at the same time each unit can be selected and operated.
- According to a further aspect of the invention the first roller blind unit includes a first spring driven roller in a first housing and the first shade member is attached by the first end to the first roller and the first shade member can be wound and unwound from the first roller into and out of the first housing upon movement of the first housing,
and the second roller blind unit includes a second spring driven roller in a second housing, a second shade member attached by a first end to the second roller and by a second end to the first housing and the second sheet can be wound and unwound from the second roller into and out of the second housing upon movement of the first or second housing. - Advantageously, a pair of parallel side guides is provided extending perpendicular to the rollers and being capable of guiding the movement of each roller blind unit.
- Advantageously, each of the first and second shade members is sized so that when extended by itself it covers the architectural opening.
- According to another aspect of the invention, the first cord guiding arrangement of the multi functional roller blind unit includes a pair of left and right guide cords which are routed through the first roller blind unit according to an H-type cord routing scheme, and advantageously the second cord guiding arrangement also includes a pair of left and right guide cords which are routed through the second roller blind unit also according to an H-type cord routing scheme.
- According to another advantageous aspect of the blind the first and/or second roller blind units include at least one cord channel through which the tension cords can be routed.
- According to another aspect the cord channel is part the first or second housing of the respective roller blind unit.
Advantageously, the cord channel is formed by a U-shape profiled housing flange which flange is closed by a flange covers shaping the channel. - According to another aspect of the invention the first and/or second housing is provided with a pair of left and right housing ends, the housing ends having an entrance to the cord channel.
- Another aspect of the invention is that the first shade member has different shade characteristics from the second shade member
- The invention will be more clearly understood from the following description, given by way of example only, with reference to the accompanying drawings, in which:
-

Figure 1 , comprises a pair of substantially parallel first and second rollerblind units profile 7 parallel to the roller blind units. First rollerblind unit 3 is movably arranged betweenprofile 7 and second rollerblind unit 5, and includes first blind sheet orshade member 9 fixed on a first spring drivenroller 11 with one end 9A (not shown) and an opposite end 9B fixed toprofile 7. - Second roller
blind unit 5 is movably arranged beneath the first roller blind unit and includes secondblind sheet 13 fixed on second spring drivenroller 15 by oneend 13A and tounit 3 by anopposite end 13B. - Also shown in
Figure 1 is a schematic representation of a cord guiding arrangement for the multi-functional roller blind, this arrangement includes a first pair of left andright tension cords blind unit 3 and a second pair of left andright tension cords second roller unit 5. Each pair of tension cords is routed in a conventional H-type routing. Tension or compression springs (not shown) are present in the cord arrangements to keep the cords tensioned. The ends of the respective cords will be fixed to the window frame directly or to intermediary stationary profiles upon mounting of theblind assembly 1. - In use either first
blind unit 3 or secondblind unit 5 can be manipulated by pulling it downward or moving it up. By such movements the unit will slide along the tension cords while at the same time deploying or winding up its sheet depending on the chosen movement. Additionally left and right side guide profiles can be used to guide the rollerblind units - As shown in
Figure 2 the first rollerblind unit 3 includes aroller 11, a housing 27, a spring bias arrangement 29 with atorsion spring 31, and a pair of left andright housing ends right covers - The
roller 11 is rotatably mounted within the housing 27 and has secured to it the first end 9A of the first covering sheet 9 (not shown). Thetorsion spring 31 is provided to bias the roller 25 in a direction to roll the coveringsheet 9 onto the roller 25 and into the housing 27. - The second roller
blind unit 5 has the same parts assembled in the same way and includes aroller 15, a housing 37, a spring bias arrangement 39 withtorsion spring 41, a pair of left and right housing ends 43a, 43b and a pair of left andright covers - The
torsion springs roller tension cords - Each housing 27, 37, includes a pair of top and bottom cord channels 47, 49. The cord channels are built up by a pair of top and bottom U-shaped profiled
flanges bottom plug tubes - In the installed multi functional roller blind of each roller blind unit preferably only the cord channels facing the adjacent roller blind unit will be used.
- In the arrangement of
Figure 1 , this means that from the first rollerblind unit 3 the bottom cord channel 49 is in use for left andright cords right tension cords left tension cord 17 is attached by a first end to a top window frame or thefixed profile 7, the cord is then routed down towards the firstroller bind unit 3, enters by leftbottom plug tube 59b into bottom channel 49 and exits at the other end by right bottom plug tube 61 b, thecord 17 continues down and will be attached to a lower right corner or portion of a window frame. Theleft tension cord 21 for the second rollerblind unit 5 is routed similarly but enters the lower rollerblind unit 5 by the top left plug tube 59a and the top cord channel 47 and exits at the other end by righttop plug tube 61 a. - The
right tension cords left siblings -
Figures 3A-3D shows the multi functional roller blind mounted in an architectural opening, having atop side 63, abottom side 65, aleft side 67 and aright side 69. Thecord tensioning arrangements units -
Figure 3A illustrates that in the closed position both first and second rollerblind units top side 63 of the architectural opening. Theprofile 7 is fixed to thetop side 63 of the architectural opening. - Upon manipulation of
top unit 3 and moving it downward to the opposite side of the architectural opening, thelower side 65, the first coveringsheet 9 is unwound from the roller and pulled to cover the entire architectural opening. The result of this action is shown inFigure 3B . - Alternatively, starting from the position of
Figure 3A when both blind units are adjacent thetop side 63, by manipulating and moving downwardly thelower unit 5, the second coveringsheet 13 is unwound form the roller and pulled to cover the entire architectural opening. The result of this action is shown inFigure 3C . - Alternatively both
