WO 2009/052822 . These strings are complicated to mount, and may be broken, mounted erroneously or become tangled in the process, thus causing the screening arrangement to malfunction or even be broken. - This problem has been attempted solved with a screening arrangement of the type mentioned initially. Such a screening arrangement is known from
JP 11-152974 A - This arrangement has the drawback that the shutter needs to be completely open in order to recharge the batteries, which in turn implies a risk of that the batteries not being sufficiently recharged. Furthermore, the batteries will need replacement at the end of their life time.
- Another drawback lies in the mounting process, which is still rather complicated in that the plug and socket system, or indeed any other battery recharging system, must be arranged with great precision to ensure proper recharging of the batteries and to avoid full power drain or damage to the recharging system during use of the shutter.
- Therefore, it is the object of the invention to provide a screening device of the type mentioned in the introduction, whereby the power supply to the electrical motor is simplified, and whereby the mounting process may be carried out in a simple and straightforward manner.

- With such a screening device electrical power may be lead from the electrical outlet in the frame through the electrcal contact means and the at least one electrical guide of the side rail, the electrical connection device of the bottom element and finally to the electrical motor driving the screening arrangement.
- Thereby a steady supply of electrical power to the motor is ensured at all times after mounting of the screening device. Thus, the need for guide cord systems, batteries and recharging systems are elimiated, which in turn ensures a screening device being lightweight, very simple and straight forward to mount on a window or indeed another opening in a building which it is desired to screen.
- According to a preferred embodiment the electrical outlet is provided with a mounting bracket comprising at least one electrical contact point, and the side rail comprises a connection element adapted for engagement with the mounting bracket, the connection element comprising the at least one electrical contact means, the at least one electrical contact means being adapted for electrical contact with the at least one electrical contact point of the mounting bracket.

- According to a further preferred embodiment the slide shoe is arranged on the bottom element in such a way that, in a mounted position of the screening arrangement on the frame of the window, it is aligned with the side rail and movable in relation to the bottom element. Thereby a screening device is provided which may be adapted to the actual width of the window or other opening in a building, in a particularly simple and robust manner.
- According to a preferred embodiment the screening arrangement further comprises a biasing means arranged on the bottom element and adapted for urging the electrical connection device against the electrical guide, whereby an improved electrical connection between electrical guide and electric motor is obtained.
- According to a preferred embodiment the first transmission means comprises a shaft rotatable by means of the motor and a gear wheel at opposite ends of the shaft, and the second transmission means comprises a rack extending in the longitudinal direction, L, of each of the side rails.

Thereby a screening arrangement is obtained which may be operated manually, e.g. in case the electrical drive means malfunctions.
- According to a preferred embodiment the screening arrangement further comprises at least one suspension element arranged on the bottom element, the suspension element being adapted to move the electrical connection device between a first position in which the electrical connection device is in electrical connection with the electrical guide and a second position in which the electrical connection device is not in electrical connection with the electrical guide. Thereby a screening arrangement is obtained in which a possibility for manual disruption of the electrical driving system is included, which may be of advantage particlularly during mounting of the device, but also e.g. when it is desired to operate the screening device manually.
- According to a preferred embodiment the side rails further comprise an outer profile and an inner profile arranged such as to form between them a guide slot for guiding the bottom element. Thereby a particularly robust and well functioning guidance of the bottom element is obtained, which in turn also leads to a more stable electrical connection between electrical guide and electric motor.

Figs 1 and 2 show an embodiment of a screening arrangement generally designated 1. As shown inFig. 1 , thescreening arrangement 1 is adapted to be mounted on a frame constituted by aframe 2 representing a window. Theframe 2 is preferably a pivotable frame, but may likewise be a stationary frame, 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. Thescreening arrangement 1 may thus be utilized in connection with e.g. windows having a frame only, windows having a sash and a frame, or in doors. - The
frame 2 has atop piece 21, abottom piece 22 and twoside pieces frame 2 furthermore comprises twoelectrical outlets 25, 26 (cf.Fig. 2 ), one on eachside piece top piece 21 or even thebottom piece 22. - In the embodiment shown, the
screening arrangement 1 comprises atop element 4 positioned at thetop piece 21, a screening body 6 (shown inFig. 1 only) and abottom element 7. At its upper end edge, thescreening body 6 is accommodated in thetop element 4 and its opposed, lower end edge is fastened to thebottom element 7. According to the invention, thebottom element 7 is adapted to be electrically operated during operation of thescreening arrangement 1, i.e. when moving thebottom element 7 and hence thescreening body 6 between the non-screening position shown inFigs 1 and3 and a screening position, in which thescreening body 6 covers the frame aperture partly or fully. To this end the bottom element comprises anelectric motor 710, cf.Fig. 3 . - Furthermore, and as shown on
Fig. 3 , thescreening arrangement 1 comprises twoside rails respective side piece frame 2 by means of fastening elements, such as screws, and to thetop element 4, e.g. by means of a snap or click connection or a plug and socket conenction. In the mounted position of thescreening arrangement 1, opposite ends of thebottom element 7 and opposite side edges of thescreening body 6 are guided in theseside rails top element 4 includes a spring-biased roller bar. However, other screening arrangements having other kinds of screening bodies and other configurations of the top element are conceivable as well. Hence, it is noted that as used herein the term "screening body" is intended to encompass all feasible types of screening bodies, examples being blinds, pleated blinds, venetian blinds, curtains, insect screens, awnings, roller shutters and shades. - Turning now to
Fig. 3 depicting thescreening arrangement 1 according to the invention, it may be seen that thetop element 4 has a left-hand side surface 414 and a right-hand side surface 415, each comprising aconnection element - Furthermore, with reference also to
Figs. 4 and 5 , thebottom element 7 and the twoside rails screening arrangement 1 comprises an electrical drive means. Arranged in thebottom element 7, the electrical drive means comprises anelectric motor 710, a first transmission means 711, 712, 713 and at least oneelectrical connection device motor 710. - In the embodiment shown, the first transmission means 711, 712, 713 comprises a
shaft 711 arranged such as to be rotatable by means of theelectric motor 710 andgear wheels shaft 711. - Arranged in the
side rail 8 the electrical drive means comprises a second transmission means 810 and twoelectrical guides 811, 812 (or electrical carriers) extending substatially in a longitudinal direction L of theside rail 8. Similarly, arranged in theside rail 9 the electrical drive means comprises a second transmission means 910 and twoelectrical guides side rail 9. - In the embodiment shown the second transmission means comprises a
rack - It is noted that other configurations of the first transmission means 711, 712, 713 and the second transmission means 810 are feasible. For instance, the second transmission means may be a rail or a track, while the first transmission means comprise wheel(s) adapted for being guided in or on the rail or track.
- It is noted that the first transmission means 711, 712, 713 and the second transmission means 810 may be mounted in such a way with respect to each other that smaller variations in the width of the frame, on which the
screening arrangement 1 is mounted, may be absorbed. For instance, thegear wheels shaft 711, and thereby in a direction perpendicular to the longitudinal extension of therack 810. Alternatively the entire first transmission means 711, 712, 713 may be mounted in such a way as to be movable with respect to the remainingbottom element 7 in a direction parallel with theshaft 711, and thereby in a direction perpendicular to the longitudinal extension of therack 810. - It is noted that in principle only one of the side rails 8, 9 need to be equipped with the electrical guides described above, and that another number than two electrical guides, particularly one electrical guide although in principle also more than two, may be provided in one of or each of the side rails.

side rail 8 extending in a longitudinal direction L (cf.Fig. 7 ) of theside rail 8, the lateral side surface facing theframe 2 in the mounted position of thescreening arrangement 1. During installation of the screening arrangement theside rail 8 is slid into place. So the electrical contact means 813, 814 on theside rail 8 are adapted to be slidable relative to theframe 2 and/or theelectric outlet 25 at least in the direction of installation. Preferably the contact means 813, 814 have a smooth surface configured to slide.

bottom element 7 comprises a biasing means 717 (cf.Fig. 5 ) adapted for urging theelectrical connection device electrical guide electrical connection devices - In the embodiment shown, a similar electrical connection system is provided in the
side rail 9 and the adjacent end of thebottom element 7 comprising thegear wheel 713. In another embodiment it is, however, feasible that the electrical connection system described above is provided in only one of the side rails and the adjacent end of the bottom element. - Furthermore, the
bottom element 7 comprises, at the end comprising thegear wheel 712, aslide shoe 716 in which theelectrical connection devices slide shoe 716 is arranged on thebottom element 7 in such a way that, in a mounted position of thescreening arrangement 1 on theframe 2 of the window, it is aligned or even fixed in relation to theside rail 8 and movable in relation to thebottom element 7. Theelectrical connection devices slide shoe 716 in any suitable way, examples being moulding, soldering, riveting, snap connection or frictional connection. - The
slide shoe 716 is arranged on thebottom element 7 in such a way that it is movable, e.g. about a pivot axis, between a first position in which theelectrical connection devices electrical guides 811, 812 (cf.Fig. 5 ) and a second position in which theelectrical connection devices electrical guides 811, 812 (cf.Fig. 4 ). - The biasing means 717 may likewise be arranged in or on the
slide shoe 716, e.g. as a suitable spring element affecting the pivot axis around which theslide shoe 716 is movable. - The
slide shoe 716 may be manually operable by means of ahandle element 721. Theslide shoe 716 may furthermore comprise a housing 720 (cf.Figs. 8 and 9 ) for protective purposes. Thehandle element 721 preferably extends through an opening in thehousing 720 as shown onFigs. 8 and 9 . The sliding shoe may be automatically operable. For example a ramp may automatically lift and lower theshoe 716, so theelectrical connection devices electrical guides side rail bottom element 7. - The slide shoe is mounted adjacent to the gear wheel as shown in the figures. Alternatively the slide shoe may be mounted in such a way that the shaft extends into the slide shoe, the gear wheel being arranged in the slide shoe, preferably in the housing of the slide shoe, or that the shaft extends through the slide shoe.
- It is noted that the
slide shoe 716 is an optional yet preferred feature of the screening arrangement, and that a similar slide shoe may be provided at the end of thebottom element 7 comprising thegear wheel 713. - It is furthermore noted that the

connection element 815 and the mountingbracket 27 do not directly fit each other, an adapter element (not shown) may be provided for insertion between theconnection element 815 and the mountingbracket 27. In yet another embodiment, theconnection element 815 may be omitted, and the electrcal contact means 813, 814 arranged on theside rail 8 may be adapted for direct contact with the electrical contact points 271, 272 of the mountingbracket 27. - It is noted that the
side rail 9 and theelectrical outlet 26 may be equipped similarly. - With reference to
