Definitions

  • the present invention relates to a screening arrangement for adjusting the light intake of a window and comprising an extensible screen.
  • the invention furthermore relates to a method for providing variable screening of a window.
  • a screening arrangement comprises a screen in the form of a blind or shade, such as a roller blind or a pleated blind.
  • a roller blind is typically comprised of a flexible screen, typically made of fabric, arranged on a roller shaft.
  • the fabric used can be of varying quality depending on the purpose. For instance, the fabric may be a light fabric, which allows a generous amount of light into the room. The fabric can otherwise be a thick fabric with a light impermeable coating to ensure a dark room.
  • the problem with this type of roller blind is that it is difficult to adjust the amount of light. The only way to adjust the light intake is to vary the covering length of the blind. In the prior art, several attempts have been made in order to alleviate this problem.
  • the screen comprises an elastic fabric provided with apertures.
  • the screen is wound on a winding tube driven by a motor, and can be deployed to a length corresponding to the window.
  • the load bar at the lower end edge of the screen is fixed in position relative to a stationary bolt or support at the lower end of the window, following which the screen is subjected to either a traction to widen the apertures, or relaxed to close the apertures.
  • an arrangement of the kind mentioned in the introduction is devised, in which the arrangement is provided with tensioning means in the form of two winding tubes.
  • the traction on the screen ensuring increased permeability during the unwinding of the screen is provided by the weight of the load bar.
  • this arrangement is dependent on partly a sufficient weight of the load bar, partly on the installation position as the arrangement is only suitable in installations in which the gravity acts entirely, or at least mostly, in the direction.
  • this screening arrangement is unsuitable for screening windows installed either horizontally or obliquely, for instance roof windows installed in an inclined roof.
  • a screening arrangement of the kind mentioned in the introduction which is furthermore characterized in that the traction means comprises a cord system including at least one traction cord having a first end in connection with the roller shaft and a second end in connection with the second end portion of the extensible screen, and a spring device to provide pre-tensioning of the at least one traction cord, the cord system being configured to apply a traction force on the extensible screen such that the tension exerted by the cord system on the extensible screen provides said first stretched state during unwinding of the extensible screen.
  • a screening arrangement which can be used in a wide range of windows, including windows installed in an inclined roof surface, or even horizontally.
  • the control of the degree of permeability of the extensible screen is improved as well.
  • permeability, permeable etc. as used herein are to be interpreted as encompassing transmission of light and heat from one side of the screening arrangement to the other. Permeability thus encompasses light permeability, including transparency and translucency, but also the ability to allow heat transfer from the inside to the outside, or vice versa.
  • a bottom bar is connected to the second end portion of the extensible screen.
  • this also opens up to the possibility of accommodating the spring device in the bottom bar.
  • the spring device is provided behind a header and/or side rails of the screening arrangement.
  • the spring device is provided behind the side rail and comprises a first, movable pulley, a second pulley fixed to a stationary part of the screening arrangement, a third pulley fixed to a stationary part of the screening arrangement, and a tension spring connected at one end to a stationary part of the screening arrangement at a fixed connection point and at the other end to a movable connection point coupled to the first pulley, the second end of each traction cord being guided around the first pulley, the second pulley and the third pulley and further to the bottom bar of the screening arrangement.
  • the spring device comprises forming at least one traction cord with at least one elastic portion.
  • the spring device provides a "cord reserve" ensuring proper functioning of the screening arrangement in that the pre-tensioning of the cord system makes it possible to accommodate a surplus length of each traction cord when the extensible screen is brought from the first stretched state to the second stretched state. Once the extensible screen is brought back from the second stretched state, the cord reserve is again released.
  • a method for providing variable screening is provided as defined in independent claim 21.
  • the pre-tensioning of the cord system may in principle be configured in relation to the driving torque and rotational speed on the roller shaft according to any suitable interrelationship which provides for the desired tension in the first and the second stretched state.
  • the pre-tensioning of the cord system is interrelated to the rotation of the roller shaft during the movement from the non-screening position via the first screening position to the second screening position, such that:
  • Figs 1 to 3 schematically illustrate embodiments of a screening arrangement 100 adapted to be arranged in a window 150.
  • the window will be referred to only as “window” and the invention is in particular intended for use in a roof window, installed in an inclined roof surface.
  • Directional terms such as “upper”, “lower” etc. relate to the position shown in the drawings.
  • the invention is in principle applicable to all types of windows for installation in all types of roofs, including flat roofs, and facades, however.
  • the window has, in a manner known per se, at least one frame encasing a window opening to be screened. In the embodiment shown in Fig.
  • a stationary frame 151 is configured to be installed in a roof surface, and an openable frame in the form of a sash 152 is connected to the frame 151 by means of a set of hinges (not shown in detail).
  • a set of hinges not shown in detail.
  • the screening arrangement 100 comprises an extensible screen 6 and has a predefined length between a first end portion 61 and a second end section 62, and is made from a material having variable properties as regards permeability, including transparency, as will be described in further detail in the following.
  • Terms such as permeability, light permeability, transparency, light intake etc. are used interchangeably in the following, and even though the terms are used in connection with light transmission from the outside to the inside in the description of the embodiments, these terms do not preclude that the permeability also includes light transmission from the inside to the outside and heat transfer from the outside or in, or vice versa.
  • the first end portion 61 is connected to a roller shaft 1 connected to drive means (not shown) such that the extensible screen 6 may be wound up on and unwound from the roller shaft 1 under rotation thereof.
  • the extensible screen 6 is typically rectangular, and the width of the extensible screen corresponds to or is slightly smaller than the length of the roller shaft. This may however be different depending on the specific installation, the width being defined between opposed side portions 63, 64.
  • the roller shaft 1 is typically positioned at the top of the window, for instance fastened by suitable brackets to one of the frames of the window. Most commonly the roller shaft 1 is arranged horizontally at the top of the window. This is however not limiting for the screening arrangement 100 which may be suitably used in any direction depending on the size and shape of the window.
  • the extensible screen 6 may thus be brought from a non-screening position in which the extensible screen 6 is wound more or less completely on to the roller shaft 1 and to one or more screening positions by moving the second end portion 62 downwards, hence typically in the direction towards the bottom of the window, as will be elaborated on below.
  • the screening arrangement 100 comprises a header 9 arranged to cover at least the roller shaft 1 at the top of the window and two side rails 10 in which the side portions 63, 64 of the extensible screen 6 are guided. Furthermore, the screening arrangement 100 comprises a bottom bar 4 connected to the free or second end portion 62 of the extensible screen 6.
  • the screening arrangement is provided in the form of an external awning in which the screen 6 in the non-screening position is accommodated in a top element forming the header 9 and connected to the top piece of the stationary frame 151.
  • Side rails 10 guiding the side portions of the screen 6 and the bottom bar 4 are connected to the header 9.
  • the side rails 10 are slidingly connected to the bottom piece of the sash 152 in a manner known per se.
  • the extensible screen 6 may in general be formed by any material such as textile made with at least one of elastic, lamellae, knits, pleat, non-woven or the like, in which a plurality of openings or apertures 8 are able to form.
  • such apertures may also be provided as interstices in a mesh, as indicated schematically in the embodiments of Figs 1 , 1a and 2 , and the term "apertures" will be adhered to in the following.
  • a traction force applied to the material in the direction of arrows A in Fig. 1 i.e. in a first direction, may stretch or extend the material in order to widen apertures 8 that may vary in size depending on the size of the traction force.
  • the first direction here corresponds to a height direction of the screening arrangement 100 as depicted in Fig.
  • the first direction corresponds to the winding and unwinding directions.
  • the apertures 8 In an unstretched, or substantially relaxed, state, the apertures 8 barely show, and hence there is little permeability. In a stretched state, the apertures 8 are increased in size in at least the first direction, and thereby light intake from a window can be varied.
  • a fabric with apertures is described in WO 2011 /150902 A1 in which the fabric or textile is elastic in a first direction and is substantially inelastic in a second direction and wherein apertures, the size of which can be controlled according to the elasticity of the fabric, are formed in the fabric or textile when the textile is stretched in the direction in which the textile is elastic.
  • the fabric will have the properties indicated in Figs 5a and 5b , as the fabric is formed as a warp, having a plurality of warp threads of elastic fibres or yarns and weft yarns Y added by conventional joining techniques and typically designed as threads arranged in pairs, one behind the other.
  • the weft yarns are substantially non-elastic, so that the screen, so that the screen may be stretched in the longitudinal direction, that is in the direction of the warp yarns, that is from the length L2 to the length L, without significantly shrinking in the transverse direction, i.e. in the direction of the weft yarns, where the dimension B in the width dimension is substantially constant.
  • Additional means may also be provided to keep the extensible screen substantially inextensible in a direction substantially perpendicular to said first direction, such that when traction is exerted on the screen in the first direction, the dimension B in the second direction is substantially unchanged.
  • means that limit the extension of the extensible screen in the first direction may also be provided. These means may inherent in the fabric used in the extensible screen, or be provided as separate elements.
  • the screening arrangement 100 comprises traction means which is operated to bring the screening arrangement from a first screening position to a second screening position, and vice versa.
  • the traction means is configured to maintain the extensible screen 6 in the first stretched state during unwinding of the extensible screen 6 until the well-defined end stop has been reached, corresponding to a first screening position, and in which the extensible screen 6 is brought to a second screening position in which the extensible screen 6 is in a second stretched state. This is carried out by continued rotation of the roller shaft 1 in the unwinding direction, and the permeability of the extensible screen 6 is decreased in the second stretched state relative to the first stretched state.
  • FIG. 2 shows the details of the screening arrangement 100 in one embodiment, the bottom bar 4 being indicated only schematically for reasons of clarity.
  • the traction means comprises a cord system including at least one traction cord 3 having a first end 3a in connection with the roller shaft 1 and a second end 3b in connection with the second end portion 62 of the extensible screen 6, and a spring device 5 to provide pre-tensioning of the at least one traction cord 3.
  • the cord system is configured to apply a traction force on the extensible screen 6 such that the tension exerted by the cord system on the extensible screen 6 provides said first stretched state during unwinding of the extensible screen 6.
  • the position of the roller shaft 1 is denoted by axis X1.
  • the cord system comprises two traction cords 3, each being associated to a respective spring device 5. By having two traction cords 3, the load is more evenly distributed.
  • each spring device 5 is positioned within the confines of the bottom bar 4 and comprises a tension spring directly connected to the second end 3b of the traction cord 3, but other arrangements are conceivable.
  • Other configurations of such a spring device to provide pre-tensioning of the traction cord or cords include the provision of a spring device placed behind the header and/or side rails, and by forming the traction cord or cords at least partially by elastic portions.
  • pre-tensioning is to be interpreted as encompassing any configurations of the cord system which allows the traction cord or cords to be kept tight at all times, and which is able to provide a "cord reserve” which serves partly to compensate for the differences in wound up length of the traction cord(s) relative to the unwound length of extensible screen during unwinding, partly to accommodate a surplus length of the traction cord(s) when the extensible screen is brought from the first stretched state to the second stretched state.
  • each traction cord 3 is connected to the second end portion 62 of the extensible screen 6 via the bottom bar 4 and to the roller shaft 1 in that a first end 3a is wound onto the roller shaft 1, here in the opposite direction of the winding of the extensible screen 6.
  • the winding of the traction cords may also be provided on a separate winding reel.
  • the winding reel may be connected directly to the roller shaft or via a suitable transmission mechanism such as a belt drive or a chain drive.
  • the screening arrangement 100 further comprises at least one idler shaft or pulley 2, here two pulleys 2, one positioned at either side of the extensible screen 6 along an axis X2 to cooperate with a respective traction cord 3.
  • a fixed pin with a low friction surface may be used.
  • the pulleys 2 are arranged substantially parallel to and at a distance from the roller shaft 1, each traction cord 3 being guided around the respective pulley 2 such that the respective traction cord 3 forms a loop between the roller shaft 1 and the second end portion 62 of the extensible screen 6, either directly to the second end portion or via the bottom bar 4.
  • the pulleys 2 are located near the end point for the travel of the extensible screen 6.
  • a positioning element comprising an optional guide roller 7, having a positioning surface arranged to position the extensible screen 6 in the predefined screening plane in those case in which a desired screening plane is defined in the deployed position.
  • the wound up position is when the extensible screen 6 is fully withdrawn and the entirety of the window opening to be screened is exposed, i.e. a non-screening position.
  • the deployed position is when the extensible screen 6 is unwound and deployed to cover the entire window opening in a first screening position.
  • the extensible screen 6 is furthermore adapted to assume a second screening position, in which the material of the extensible screen 6 is in a second stretched state and is stretched to a reduced level relative to the first stretched state and the apertures 8 are in a more closed condition.
  • a partially unwound extensible screen 6 is shown.
  • the roller shaft 1 is rotated in a first rotational direction (counter-clockwise in the embodiment shown) and the extensible screen 6 moves downwards.
  • the bottom bar 4 may also be positioned in a number of intermediate positions in between to provide a variety of screening positions.
  • the extensible screen 6 is in a first stretched state, as indicated schematically by the relatively large distance between the dashes.
  • the traction cords 3 are wound onto the roller shaft 1 during the unwinding of the screen 6.
  • the extensible screen 6 is deployed, i.e. unwound from the roller shaft 1, and the extensible screen 6 is in a first stretched state.
  • the position of the second end portion 62 of the extensible screen, or of the bottom bar 4, relative to the window opening to be screened is in a well-defined end point, which may be mechanically defined, for instance by an abutment, or controlled electronically by suitable programming of the drive means.
  • the roller shaft 1 may receive its driving torque to unwind and wind up the extensible screen 6 from a motor.
  • the drive means of the embodiment of Fig. 2 comprises a tubular motor incorporated in the roller shaft 1, but may also be positioned externally of the roller shaft, in mechanical connection with the roller shaft.
  • the tubular motor is connected to a control system including calibration means such as a revolution counter and/or one or more sensors.
  • the motor may thus be configured to provide the screening arrangement 100 with a suitable torque at a suitable speed over predefined time periods.
  • the drive means of the screening arrangement is typically calibrated, for instance by a revolution counter, in order to detect the deployed position.
  • the extent of the desired stretch of the extensible screen 6 is able to be determined and programmed into the control means.
  • One simple manner of achieving the well-defined end point is by programming the control means to detect an increase in the power consumption of the tubular motor.
  • Fig. 3b the extensible screen 6 is in a first stretched state in this first screening position which substantially corresponds to the level of tension during unwinding, i.e. in Fig. 3a.
  • Fig. 4 illustrates the relative magnitudes of the tensional forces in the cloth of the extensible screen 6 and the cord system/spring device, respectively, at the positions indicated in Figs 3a to 3d .
  • Fig. 4 illustrates the relative magnitudes of the tensional forces in the cloth of the extensible screen 6 and the cord system/spring device, respectively, at the positions indicated in Figs 3a to 3d .
  • the pre-tensioning of the cord system is interrelated to the rotation of the roller shaft 1 during the movement from the non-screening position via the first screening position to the second screening position, such that the tension in the extensible screen 6 exceeds the tension of the cord system during the movement from the non-screening positon to the first screening position.
  • Fig. 3c illustrates a second screening position, which has been reached following a continuing rotation of the roller shaft 1 in the first rotational direction, i.e. to unwind the extensible screen 6 further to reach a second stretched state.
  • position "3c” it is noted that the tension in the extensible screen 6 is lower than the tension in the cord system in this second screening position. This results in the permeability of the extensible screen 6 being lower than in the first screening position, thus attaining a darkening effect.
  • the roller shaft 1 may then be rotated even further to allow the extensible screen 6 to attain the position shown in Fig. 3d , in which the extensible screen 6 is substantially completely relaxed, such that a minimum permeability is obtained.
  • the relationship between the tension in the screen 6 and the cord system including the spring device is illustrated in Fig. 4 , position "3d".
  • the level of tension of the cord system relative to the tension of the extensible screen in the second screening position shown in Fig. 3c , and the amount of screening material of the extensible screen 6 remaining on the roller shaft 1 to allow further rotation and a completely relaxed condition as in Fig. 3d is of course dependent on the predefined length of the extensible screen 6 as defined between the first end portion 61 and the second end portion 62. By definition, this predefined length corresponds to a completely relaxed state of the extensible screen 6.
  • the predefined length of the extensible screen 6 may alternatively be configured relative to the height of the window opening to be screened as one of the following options:
  • the maximum stretched length of the extensible screen in accordance with the predefined length and/or the height of the window opening to be screened.
  • the maximum stretched length may be of use in defining the relationship between the first and second stretched state, but also in the dimensioning of for instance the header of the screening arrangement in accordance with the cloth thickness of the extensible screen.
  • the ratio between the maximum stretched length and the predefined length of the extensible screen 6 lies in the range 1.2 to 2.0, preferably 1.3 to 1.7, even more preferably about 1.5.
  • the relationship between the torque provided by drive means on the roller shaft and the force which the traction cords 3 influence the bottom bar 4 depends on several factors including the dimensioning of the roller shaft 1, the elasticity, thickness and predefined length of the extensible screen 6, of whether the traction cords 3 are wound up on a separate winding reel or on the roller shaft 1 itself, and if so, on a part of reduced diameter thereof; and last but not least the configuration and dimensioning of the spring device acting to provide a pre-tensioning of the traction cords 3.
  • the cord system is operable to provide a "cord reserve" inherent in the spring device 5 to ensure proper functioning of the screening arrangement 100.
  • the pre-tensioning of the cord system provides for a cord reserve such that a surplus length of the traction cord or cords 3 is accommodated when the extensible screen 6 is brought from the first stretched state to the second stretched state.
  • This cord reserve is then again released when the extensible screen 6 is to be brought back to its collapsed position by rotating the roller shaft 1 is subsequently rotated in a second rotational direction (clockwise in the embodiment shown), opposite to the first rotational direction shown in Figs 3a to 3d , and thus returns the extensible screen 6 on to the roller shaft 1.
  • the roller shaft 1 is then set to rotate further in the second rotational direction.
  • the traction cords 3 will at the same pace unwind from the roller shaft 1 and follow the path of the extensible screen 6 until the extensible screen 6 is in a wound up position.
