Description

Screening arrangement having a first screening device and a second screening device having a freely movable screening body

The present invention relates to a screening arrangement com- prising a first screening device having a screening body adapted for screening an aperture of a frame and comprising an upper end edge and a lower end edge, said lower end edge being fastened to a first lower operating element, a second screening device having a screening body adapted for screening an aperture of a frame and comprising a lower end edge and an upper end edge, said upper end edge being fastened to a second upper operating element and the lower end edge fastened to a second lower operating element, a top element adapted to be positioned at a top piece of the frame, two side rails adapted to be connected to side pieces of said frame, each operating element extending substantially in parallel to each other in a first longitudinal direction defining, in a condition of use, a width direction, said first longitudinal direction being substantially perpendicular to a second longitudinal direction defining a height direction, each side rail extending, in the condition of use, substantially perpendicularly to each operating element in the second longitudinal direction and including at least one longitudinally extending track.

When designing screening arrangements for screening an aperture in a frame of for instance a window, a number of factors must be considered in order to meet customers' demands. The requirements for screening the aperture may depend on the season, time of the day etc. Furthermore, the fact that the space available for screening devices in the frame is limited entails that great care must be taken when designing screening devices for meeting such demands in order to secure sufficient stability and reliability during operation. Screening arrangements setting out to meet such varying requirements while still being within the space limitations are disclosed in, e.g., EP1022428 and WO 2006/050728.

Furthermore, it is known to have a screening arrangement with one screening device only, this screening device having two independ- ently movable operating elements, which is especially appreciated in use due to the inherent flexible use.

However, with the above screening arrangements it has not proven possible to meet all of the requirements to flexibility set by to- day's customers.

With this background it is an object of the invention to provide a screening arrangement providing increased flexibility during use.

This and further objects are met by a screening arrangement of the kind mentioned in the opening paragraph, which is furthermore characterized in that said first lower operating element, said second upper operating element and said second lower operating element being movable independently of each other in said second longitudinal direction, the operating elements being guided in the same track in each side rail. By making all of the operating elements movable independently of each other, a larger number of varying screening positions are obtainable in comparison with the prior art arrangements. Hence, the screening arrangement is very flexible in use. For instance, the two screening devices may be chosen and positioned such that the upper portion of the frame aperture is covered by a roller blind preventing direct sunlight from entering the room, whereas the second screening device may be positioned in an arbitrary position in the lower portion of the frame. The operating elements of the second screening device may thus be distanced from each other to a desired extent to provide a pleasant shadowing effect.

In order to ascertain correct operation of the screening arrangement, each screening device may comprise at least one cord system including a plurality of cords.

Such cord systems are advantageously provided in that the first screening device comprises a parallel guidance cord system including two cords, each cord being guided through said first lower operating element. The parallel guidance cord system provides for parallelism between the operating element and the top element of the screening arrangement. Alternatively or additionally, the second screening device may comprise a parallel guidance cord system including two cords, each cord being guided through said second upper operating element, and a holding cord system. The holding cord system holds the screening body in shape. This is particularly important in case the screening arrangement is mounted in for instance a roof window mounted in an inclined roof surface.

In a further development of this embodiment, the holding cord system comprises a holding cord extending from the upper corner of the sash through the operating element through a first set of apertures of the screening body, and along the operating element, along the opposite sash side piece, and returns to operating element, up through the screening body through a second set of apertures to operating element, through operating element and up back to the upper sash corner. A pleasant appearance and a possibility of making the internal mechanism of the first screening device more inconspicuous are obtained in an embodiment, in which the screening arrangement furthermore comprises a top rail extending in said first longitudinal direction.

In a further development of this embodiment, which is particu- larly advantageous with respect to mounting of the screening arrangement, the screening arrangement further comprises a set of angular brackets, each angular bracket having a first leg being accommodated in first reception means in the form of a track in the back side of the top rail, and each angular bracket having a second leg accommodated, in the condition of use, in reception means in the form of a track in the back side of a respective side rail.

Correct operation of the screening arrangement is facilitated by an embodiment, in which the operating elements comprise side guidance means adapted for cooperation with the track in the side rails. A particularly compact appearance of the screening arrangement is achieved in an embodiment, in which the second upper operating element is adapted to be moved to a position in which it overlaps the first lower operating element slightly. This reduces the overall height of the two abutting operating elements of the first and second screening devices, respectively.

In order to facilitate the mounting, the screening arrangement may have a supply condition and a condition of use, in said supply condition, at least one fitting is releasably connected with the top element and the operating elements.

In principle, the two screening devices of the screening arrangement may be of any suitable kind. However, it is preferred that the first screening device is a rolling blind and the second screening device is a folding blind. This provides for a good combination of screening possibilities.

In the following the invention will be described in further detail by means of examples of embodiments with reference to the schematic drawings, in which

Figs 9 and 10 show, on a larger scale, perspective views of further details of the screening arrangement of Fig. 1; and Figs 11 to 15 are perspective views of a window provided with a screening arrangement in an embodiment of the invention shown in different positions.

Figs 1 to 10 show an embodiment of a screening arrangement generally designated 1. As shown in Figs 1 and 5, the screening ar- rangement 1 is adapted to be mounted on a frame constituted by a sash 2 representing a window. The sash 2, in turn, is adapted to be connected with a stationary frame (not shown), which in a mounted position of the window lines an opening in a building. It is noted that the term "frame" is to be understood as incorporating any substantially rectangular structure positioned in any opening in a building, whether in a wall or the roof, and surrounding an aperture to be screened. Although the sash shown in Figs 1 and 5 is the sash of a roof window and the screening arrangement 1 is mounted on the sash 2 of the window, a screening arrangement according to the invention may just as well be mounted on the stationary frame instead of the sash and may also be utilized in connection with e.g. windows having a frame only, or in doors. The sash 2 has a top piece 21, a bottom piece 22 and two side pieces 23 and 24 surrounding an aperture, which is covered by a suit- able panel element such as a glazing in the form of an insulating pane (not shown).

The screening arrangement 1 comprises two screening devices 100 and 200 to be described in further detail below. Furthermore, the screening arrangement 1 includes a top element 4 adapted to be posi- tioned at the sash top piece 21 such that a top rail 440 of the top element 4 extends in a first longitudinal or width direction. Side rails 8, 9 are adapted to be positioned at the left-hand side piece 23 and right- hand side piece 24, respectively, to extend in the second longitudinal or height direction. The terms "left-hand" and "right-hand" refer to the ori- entation shown in for instance Figs 1 and 5 and are utilized for reasons of convenience only. Similarly, the terms "front" and "back" are utilized to denote the sides of the screening arrangement, "front" being the side intended to face inwards into the room of the building, and "back" the outwards facing side. The first screening device is a roller blind, having in a manner known per se a spring-loaded roller bar at the top of the frame, from which bar the screening body is unrolled in order to obtain a screening position. In the embodiment shown, the first screening device 100 is a roller blind having black-out properties. A detailed description of an ex- ample of such a black-out blind is present in Applicant's international application No. PCT/DK2007/050049, the contents of which are incorporated herein by reference. The first screening device 100 comprises a screening body 106 and an operating element 172, in the following re- ferred to as first lower operating element 172. At its upper end edge, the screening body 106 is accommodated in the top element 4 and its opposed, lower end edge is fastened to the first lower operating element 172. The first lower operating element 172 extends in a first longitudinal direction defining a width direction. The first longitudinal direction is substantially perpendicular to a second longitudinal direction defining a height direction. Thus, the width direction is parallel to the top and bottom pieces 21 and 22 and the height direction to the side pieces 23 and 24 of the sash 2. In the top element 4, means for rolling-up the screening body are provided, for instance of the kind mentioned in the above- mentioned international application.

In the embodiment shown, the second screening device 200 is a pleated blind comprising a screening body 206 including a number of pleats of any suitable material, e.g. a textile material. The screening body 206 could also be a pleated blind having a cell structure. At its upper end edge, the screening body 206 is fastened to a second upper operating element 271 and its opposed, lower end edge is fastened to a second lower operating element 272. The second upper and lower operating elements 271, 272 extend substantially in parallel to each other in the first longitudinal or width direction. Eventually, the screening arrangement comprises a plurality of cords constituting one or more cord systems to ensure proper operation of the screening arrangement. In principle, there should be one parallel guidance cord system for each operating element. However, it has turned out sufficient to utilize one parallel guidance cord system for the first screening device 100 and one parallel guidance cord system for the second screening device 200 as will be described in further detail below. Referring in particular to Fig. 6, there are thus two cord systems of the second screening device 200: A first, parallel guidance cord system and a second, holding cord system. The first cord system, i.e. the parallel guidance cord system, comprises two cords, of which one cord 291 (cf. Fig. 6) being adapted to extend from the right-hand lower corner of the sash, up through or along the second upper operating element 271 and further up to the top element 4. The other cord (not shown) is routed in a mirror-inverted manner. At the top element 4, each cord may be connected with a respective pre-tensioning device adapted to be connected with the top element 4 in a track and/or to press against the top cover portion of a cover 430. Alternatively or additionally, there may, as shown, be a pre- tensioning device in the form of a spring 271a in the operating element 271. The cord 291 forms a loop 291a, the engagement between the loop 291a and the spring 271a being carried out in a manner known per se. The other operating element 272 may be provided with a similar parallel guidance cord system, or parallelism may be ensured by the second cord system, the holding cord system. The pre-tensioning devices entail that the cords are held at a suitable tension all of the time, thereby ensuring that the operating elements 271 and 272 are at all times kept substantially in parallel with the top and bottom pieces 21, 22 of the sash 2 during operation of the screening arrangement 1. In the mounted position, the cords are hidden behind the side rails 8, 9. The ends of the cords 291 are connected to the screening arrangement itself and/or the sash near the sash bottom 22 and top 21 pieces in any suitable manner, for instance as shown and described in Applicant's co- pending application. The second cord system, i.e. the holding cord system, comprises a holding cord 293 provided to extend in a closed loop. Referring to the embodiment shown, the route of the holding cord 293 extends from one end connected with the other end (for instance by means of a simple knot or in any other manner) at the upper corner of the sash through the operating element 271 through a first set of apertures of the screening body 206, and along the operating element 272, along the opposite sash side piece. The cord 293 makes a turn near the bottom sash piece 22 and returns to operating element 272, up through the screening body through a second set of apertures to operating element 271, through operating element 271 and up to the upper sash corner. Another holding cord (not shown) correspondingly runs in mirror-image fashion in relation to the central vertical axis of Fig. 6 between the diametrically opposite corners. To provide proper tension of the holding cord 293, a spring 272a is arranged in operating element 272. By the illustrated position of the spring 272a, an excellent parallel guidance of the operating element 272 is achieved, although a spring alternatively or supplementary could be arranged at one of the cord holders at the ends of the cords. These cords, too, may be held or guided in any suit- able manner at the diametrically opposite corners of the frame or sash.

Installation of the entire screening arrangement 1 in a frame, for instance the sash 2 of Figs 1 and 5, is carried out in the following manner:

The first screening device 100 of the screening arrangement 1 is provided in its supply condition. At the installation site, the top element 4 is connected to the frame, i.e. for example the sash 2. In the embodiment shown and described in the above, this is thus carried out by guiding coupling members on the outer side of end pieces (not shown) of screening device 100 over bracket members positioned at the upper ends of each sash side piece. A bracket (not shown) for connection of the cord systems is fastened to the each of the side pieces 23, 24, near the bottom piece 22. Following this, the side rails 8, 9 are joined to the top rail 440 at the mitred ends by means of the angular brackets 85. A more detailed description of the manner of mounting the screening arrangement is disclosed in Applicant's co-pending international applications No. PCT/DK2007/050047 and PCT/DK2007/050157, the contents of which are incorporated herein by reference.

In the step of joining the side rails 8, 9 to the top rail 440, each side rail 8, 9 is brought from a position, in which the side rail 8, 9 is out of alignment with the second longitudinal direction, to a position, in which the side rails 8, 9 are in alignment with the second longitudinal direction, during the step of connecting the side rails 8, 9 to the top rail 440.

Fig. 2 shows the first screening device 100 in a condition of use of the screening arrangement 1 but before the second screening device 200 has been mounted. Further details shown in Fig. 2 are top element 4 and side rails 8, 9. The screening arrangement 1 in the embodiment shown may either be delivered with the details shown in Fig. 2 in one package and the second screening device 200 in a further one. In the supply condition, a set of angular brackets (not shown) is connected to the top rail 440 of the top element 4. This operation is advantageously carried out by a suitable tool to secure that the angular brackets assume correct positions. The top rail 440 has two ends, which in the em- bodiment shown are mitred, and of which the left-hand mitred end 445 and the right-hand mitred end 446 are indicated in Fig. 2. The mitred ends 445, 446 are adapted to be joined to a respective mitred end of the side rails 8, 9. The top rail 440 has been joined to side rails 8, 9 in joints by means of angular brackets 85. Opposite ends of the first lower operating element 172 are introduced into these side rails 8 and 9. Operating element 172 may now be moved to an arbitrary position in the sash aperture, thus providing adequate screening by means of the screening body 106. During operation, the operating element 172 is guided in the side rails 8,9 by means of side guidance means in each end.

In Figs 3 and 4 the second screening device 200 of the screening arrangement 1 is shown in a supply condition attained at the manufacturer and indicating the condition or state, in which the second screening device 200 is supplied and delivered. As shown in Figs 3 and 4, the second screening device 200 is supplied in a condition, in which the operating elements 271, 272 and the screening body 206 are held together by means of two fittings 210. In the embodiment shown the fittings are identical to each other. Although not shown in detail, the cords 291, 292 of the guidance cord system and the cords 293 of the holding cord system are secured in the fittings 210. Each operating element 271, 272 is provided with side guidance means 2701, 2702 in each end. The side guidance means are adapted for cooperation with a track in the side rails.

Fig. 5 shows the screening arrangement 1 in an intermediate position between the supply condition and the condition of use, as the operating elements 271, 272, the screening body 206 and the cords of the cord systems are still secured to each other by means of the fittings 210. The fittings 210 are releasably connected to the operating ele- ments 271, 272 in any suitable manner, for instance by means of snap engagement means for cooperating with the operating elements 271, 272, respectively, to provide positive engagement with these elements. Other means for releasable connection are conceivable as well, including the use of adhesive, interlocking elements of for instance the VELCRO® type etc. The fittings 210 assist in the mounting of the screening arrangement by keeping the cords securely without the risk of entangling of the cords. Alternative means for holding the cords temporarily to the fitting include the use of a supplemental fitting separate from the fitting 210 and designed more or less exclusively for holding the cord, and may be quite simple. In principle, the cords could be attached temporarily to e.g. the second lower operating element 272 by adhesion.

In the condition of use of the screening arrangement 1 shown in Fig. 1, the fittings 210 have been removed, and the cord systems attached properly as will be described in further detail below. The operat- ing elements 271, 272 are movable independently of each other in the second longitudinal direction, for instance to the position shown in Fig. 1. In the embodiment shown, the operating elements 271 and 272 are adapted to act as handles during operation of the screening arrangement 1, i.e. when moving one or both of the operating elements 271 and 272 and hence the screening body 206 between a non-screening position corresponding to the position shown in Fig. 1 and a screening position, in which the screening body 206 covers the sash aperture partly or fully. However, instead of being manually operated, the screening arrangement may be operated by other means, e.g. by elec- trical operating means.

Consequently, the screening arrangement according to the invention contains three operating elements that are movable independently of each other to obtain a variety of non-screening and screening positions. Examples of non-screening and screening positions are given in Figs 11 to 15, to be described in further detail below.

Fig. 7 shows a particular feature of the present invention. In the condition of use, the two screening devices are operable substantially in the same plane. This is due to the fact that the ends of each op- eratϊng element 172, 271 and 272 are guided in the same track in each side rail 8, 9 by means of the side guidance means at each end of the respective operating element. As indicated in Fig. 7, the second upper operating element 271 may assume such a position relative to the first lower operating element 172 of the first screening device 100 that these elements overlap slightly by a distance e.

Referring now to Figs 8, 9 and 10, the structure of the top element 4 and the side rails 8, 9 will be described in more detail.

The side rails 8, 9 are joined to the top element 4 by means of angular brackets 85 to form a mitre joint between the top rail 440 of the top element 4 and the respective side rail 8 and 9. Just as the top rail 440 has a predetermined height, each side rail 8, 9 has a predetermined width, and in the embodiment shown the predetermined height is substantially the same as said predetermined width, the mitre joint thus being a 45° mitre joint. Other angles are conceivable, however, this en- tails that a similar configuration of the front sides of the three elements, i.e. top rail and two side rails, is not achievable.

In Fig. 9, right-hand side rail 9 will be described, the left hand side rail 8 having a corresponding, however mirror-inverted configuration: The side rail 9 has a front side 914, a back side 915, a longer edge 916 and a shorter edge 917, and extends in a second longitudinal direction between a first end and a second mitred end 919. In the back side 915 a track 920 acting as a reception means for the angular bracket 85 is provided. A further track 921 having a longitudinally extending aperture 922 is adapted for receiving the side edge of the screening body 106 of the first screening device 100 and one end of each operating element 172, 271, 272. A flange 923 extending at substantially right angle to the plane defined by the two longitudinal directions, i.e. by the track 920, abuts, in the mounted position, the inner side face of the frame side piece 24, i.e. the face closest to the panel element of the window. The small flange portion 924 overlaps part of the front face of the frame side piece 24 to provide for an overlap between the side rails and the frame side pieces. For use in frames having a bevelled inner side face, i.e., in which the inner side face forms an angle slightly larger than 90° with the front face, the side rails of the screening arrangement may be formed with a corresponding angle between the flange 923 and the plane defined by the track 920. Eventually, the side rail 9 is provided with an aperture 925 located in flange 923. The aperture 925 is situated at a distance from the second mitred end 919. There may be more than one aperture along the side rail 9. The aperture or apertures are intended for receiving suitable fastening means. Such means may include screws introduced through aperture 925 and the other apertures along the side rail 9. As the uppermost aperture 925 of the side rail 9 is positioned at a distance from the second mitred end 919, a slight de- formation of the side rail 9 may take place such that the mitre joint is not compromised. In this manner, the screening arrangement takes up the tolerances of the frame or sash without affecting the mitre joint.

Fig. 10 shows the top rail 440 of the top element 4 with reception means for the angular brackets 85 in the form of a first track 447 on the back side of the top rail 440. The first track 447 is constituted by the back side surface 450 of the top rail 440 and the walls 451 protruding from the back side portions 454, 455 extending on the back side of the top rail 440. Fig. 10 also shows a second track 448, which is constituted by the above-mentioned walls 451 and the walls 453 also protrud- ing from the back side portions 454, 455 extending from the top rail 440. The walls 451, 453 and back side portions 454, 455 constituting the tracks 447, 448 extend in the longitudinal direction of the top rail 440 providing the tracks 447, 448 with parallel planes, which provides for an easier production process for instance by extrusion. Referring now to Figs 11 to 15a number of the non-screening and screening positions obtainable by the screening arrangement will be described.

Fig. 11 shows a window and a screening arrangement that has been brought to a position, in which the aperture of the frame is sub- stantially non-screened. That is, the first screening device 100, i.e. the roller blind, is rolled up and the first lower operating element 172 is close to the top element 4 and hence to the sash top piece 21, possibly even to such an extent that part of the first lower operating element 172 is accommodated in the top element 4. The second screening device 200, i.e. the folding blind, is positioned at the sash bottom piece 22 and the folds of the blind are closely packed between operating elements 271 and 272.

A further non-screening position is shown in Fig. 12, in which the first screening device 100 is rolled up at the top element 4. Contrary to the position shown in Fig. 11, the second screening device 200 has been moved to a position just below the first screening device 100. As the operating elements 172, 271 and 272 are all operable in the same track in the respective side rail and hence moved within the same plane, the second upper operating element 271 abuts on and possibly overlaps slightly the first lower operating element 172. However, all operating elements are relatively slender and as mentioned, the first lower operating element 172 may be partly accommodated in the top element 4 and the second upper and first lower operating elements 172, 271 overlap slightly. This entails that the degree to which the sash aperture is affected by the screening devices in the non-screening position is minimized. Examples of heights of each operating element are 1 to 4 cm, more specifically 2.5 cm.

In Fig. 13, one screening position is shown, in which the first lower operating element 172 of the first screening device 100 has been moved downwardly in the track of the respective side rail 8,9. Hence, the screening body 106 screens an upper portion of the aperture. The second screening device 200 is in a position, in which the second lower operating element 272 abuts on the sash bottom piece 22 and the sec- ond upper operating element 271 has been moved upwardly in the track in the respective side rail 8,9. The screening body 206 of the second screening device 200 thus screens a lower portion of the aperture.

In Fig. 14, the position of the first screening device 100 corresponds to that of Fig. 13. The second screening device 200 is positioned substantially in continuation of the first screening device 100, as the upper edge of the second upper operating element 271 abuts on and overlaps the lower edge of the first lower operating element 172. One portion of the aperture is hence screened by the cloth of the roller blind, and another portion by the folds of the screening blind.

In Fig. 15, the first screening device 100 is in its maximum screening position, as the cloth of the roller blind covers substantially the entire aperture. The second screening device 200 is in a position corresponding to that of Fig. 11, i.e. folded up at the sash bottom piece 22.

The invention should not be regarded as being limited to the described embodiments. Several modifications and combinations of the different embodiments will be apparent to the person skilled in the art.
