Definitions

  • the present disclosure relates to screening devices for screening a window, and more particularly to a screening device with a screen with an adjustable length in which the position of the free end of the screen can be controlled with an electric drive.
  • the disclosure also relates to a method for controlling the position of the free end of a screen of a screening device for screening a window.
  • EP 0 845 572 A1 discloses a device for controlling and actuating a venetian blind in a double-glazing unit of the type constituted by a rectangular frame which supports at least two panes which are mutually parallel and spaced so as to form a chamber isolated from the outside and inside which chamber the venetian blind is accommodated and moved.
  • the venetian blind is moved by means of an electric motor.
  • the device comprises at least one permanent magnet which is arranged on a bottom element of the venetian blind and at least one sensor which is fixed to the frame of the double-glazing unit in a specific position in order to signal that the venetian blind has passed and/or has reached the position of the sensor.
  • This device has the drawback that only a very limited number of positions for the venetian blind may be obtained since for each position in which it may be desired to position the venetian blind a sensor must be provided.
  • a sensor in case a high degree of freedom in choice of positions for the screening arrangement is desired a correspondingly high number of sensors would be needed.
  • the construction with a large number of magnets would be rather complicated and expensive.
  • Another drawback lies in the arrangement of the fixed sensors on the frame of the double-glazing unit which may cause the sensors to form an obstruction or even be subjected to damage e.g. when cleaning the window, and is furthermore, this solution aesthetically unappealing.
  • a roller blind material is wound on a spindle rotated by an electric drive motor.
  • the power supply for the electric drive motor is controlled by sensors positioned at each end of the required blind movement.
  • the blind material is wound on a shaft, contained in a housing and driven by the electric drive motor.
  • a rod forms the lower edge of the blind. Rotation of the shaft in one direction lowers the blind to a point and rotation in the other direction raises it to a point. Magnets in one end of the rod activate reed switches at the end positions of the blind to switch off the electric drive motor.

  • a window screening device that has an inexpensive, simple and robust user interface for manually adjusting the position of the free end of the screen, thereby adjusting the length of the screen and the area of the window covered by the screen.
  • the provision of a manually freely adjustable position indicating element and arrangement that ensures that the free end of the screen follows the position of the position indicating element in a slave like manner provides for an intuitive user interface.
  • This new user interface can be used in addition to a remote control that is configured to adjust the position of the screen.
  • the device allows for free positioning the free end of the screen anywhere between the completely retracted and completely extended position of the screen
  • the circuit or processor is configured to control the longitudinal position of the free end as a slave of the longitudinal position of the position indicator.
  • the sensor arrangement is configured to detect the direction of the detected difference in longitudinal position between the actual longitudinal position of the free end and the actual longitudinal position of the position indicator.
  • the process or control circuit is able to determine in which direction to move the free end of the screen by means of the electric drive.
  • the sensor arrangement and the circuit or processor are arranged to form a closed loop to control the longitudinal position of the free end with the aim to minimize the detected difference in longitudinal position between the actual longitudinal position of the free end and the actual longitudinal position of the position indicator.
  • the position indicator is disposed on the elongated guide member.
  • the position indicator is slidably positionable along the elongated guide member.
  • the screening device further comprises two parallel spaced rails for guiding the two edges of the screen.

  • the position indicator is arranged detachably on one of the two side rails.
  • the position indicator is releasably coupled to the free edge so that the position indicator moves in unison with the free edge when the free end moves longitudinally.
  • the position indicator is magnetically coupled to the free end or mechanically coupled to the free end with a certain degree of flexibility that allows minor displacement in the longitudinal direction.
  • the object above is also achieved by providing a method for controlling the position of a free end of a screen of a screening device for screening a window, the screen having a variable length, a fixed width between two edges of the screen and a positionable free end, the longitudinal position of the free end determining the length of the screen and an electric drive operably connected to the screen for adjusting the position of the free end, the method comprising detecting the difference between the actual longitudinal position of a manually positionable position indicator and the actual longitudinal position of the free end, and activating the electric drive to move the free edge in a direction that reduces the detected difference in in longitudinal position.
  • This method provides for an intuitive way for a user or operator to adjust the position of the screening device.
  • the method further comprises deactivating the electric drive when the detected difference is zero or below a predetermined threshold.
  • the method further comprises manually positioning the position indicator for indicating a desired longitudinal position of the free end.

  • the frame 20 has a top piece 21, a bottom piece 22 and two side pieces 23 and 24 surrounding an aperture, which is covered by a suitable panel element such as a glazing in the form of an insulating pane.

  • the positon of the free end 4 can be adjusted by electric drive means connected to the screen to e.g. when moving the free edge 4 and hence the screen 5 between the non-screening position shown in Fig. 1 and a screening position, in which the screen 5 covers the frame aperture partly or fully shown in Figs. 2A and 2B .

  • the top element 3 includes a spring-biased winding shaft.
  • the term "screen” is intended to encompass all feasible types of screens, examples being blinds, pleated blinds, venetian blinds, curtains, insect screens, awnings, roller shutters and shades.
  • the screening device 100 further includes a position indicator 6.
  • the position indicator 6 is arranged on an elongated guide member that extends close to and parallel with one of the two edges of the screen 5.
  • the elongated guide member can be one of the side rails 1, 2.
  • the elongated guide member can be formed by a rod or string that extends close to and parallel with one of the edges of the screen 5.
  • the position indicator 6 is disposed on the elongated guide member such as to be displaceable in the longitudinal direction thereof, i.e. in a direction between the top element 3 and the end of the maximum longitudinal extension of the screen 5, e.g. the end of the side rail 1, 2 opposite to the top element 3.
  • the position indicator 6 is arranged on side rail 2.
  • the position indicator 6 may be continuously or stepwise displaceable in the longitudinal direction of the side rail 2 by a user or operator.
  • the position indicator 6 is disposed such on the elongated guide member that is will stay in the position selected by a user or operated, i.e. the position indicator 6 will not slide down under the influence of gravity.
  • the position indicator 6 is displaceable along the substantially entire possible longitudinal extend of the screen 5 in order to define a position anywhere substantially 0 and 100% of the possible longitudinal extend of the screen 5.
  • the position indicator 6 is manually displaceable to manually define any arbitrary position of the screen 5.
  • the screening device 100 further comprises a sensor arrangement for determining any difference d between the longitudinal position of the free edge 4 and the position indictor element 6.
  • Fig. 2A shows a situation where a user has move the position indicator 6 downwards from a higher position where the position indicator 6 is shown in uninterrupted lines to a lower position where the position indicator 6 is shown in interrupted lines.
  • the sensor arrangement detects the difference d in longitudinal position of the free end 4 and the position indicator 6.

  • the sensor arrangement is connected to a circuit for or processor that controls the action of the electric drive.
  • the circuit for or processor is in receipt of a signal form the sensor arrangement indicative of a difference in longitudinal position and the direction thereof.
  • the circuit or processor Upon detection of a difference in position and the direction thereof the circuit or processor instructs the electronic drive to adjust the position of the free edge in the detected direction of the difference in longitudinal position, thereby reducing the difference in longitudinal position.
  • the circuit or processor continues to move the free edge until the sensor arrangement indicated that there is no difference in position, or until the difference in longitudinal positon has dropped below a predetermined threshold. When this happens the free end 4 and the position indicator 4 are located in a substantially the same longitudinal position, there is longitudinal overlap.
  • the position indicator 6 and the bottom element or free edge 4 have the same longitudinal position. There is no physical overlap required and the position indicator 6 may merely be aligned with the bottom element 4. Thus, the position indicator 6 acts as a guide and sets a target destination for the bottom element and the free end or bottom element 4 is a slave to the position indicator 6.
  • the bottom element positioning device will be described in detail further below.
  • an operator or user When operating the screening device 100, an operator or user displaces or slides the position indicator 6 from its current or initial position to a desired position illustrated on Fig. 2A by showing the position indicator 6 in interrupted lines. Thereupon the bottom element is moved, particularly by activating the electrical drive, in direction of the arrow shown in Fig. 2A to the desired position in which the position indicator 6 and the bottom element 4 are in the same longitudinal position again. The bottom element 4 is stopped when the position indicator 6 reaches the longitudinal position of the bottom element 4, as shown on Fig. 2B . The screen 5 has thus arrived at the desired position.
  • FIG. 3 and 4 another of a screening device 101 is shown in a perspective view and a side view, respectively.
  • the electric drive of the screening device 101 is arranged in the bottom element 4.
  • the sensor arrangement includes two sensor elements; a free end component 8 and a position indicator component 10.
  • the free end component includes a magmatic element 8, such as a plate of magnetic material and the position indicator component is a permanent magnet 10.
  • the sensor elements 7, 9 are Reed or Hall sensors. Since the sensor elements 7 and 9 are spaced longitudinally, the difference in signal between the two sensor elements 7 and 9 indicates the direction of the difference in longitudinal position between the free and 4 and the position indicator 6. Assuming that the window and the covering device are arranged vertically, a stronger signal from the higher placed sensor 7 than from the lower placed sensor 9 is an indication that the position indicator 6 has a longitudinal position that is higher than the free end 4 and thus the free end 4 should move upwards in order to reduce the difference in longitudinal position between the free end 4 and the position indicator 6.
  • a stronger signal from the lower placed sensor 9 than from the higher placed sensor 7 is an indication that the position indicator 6 has a longitudinal position that is lower than the free end 4 and thus the free end 4 should move downwards in order to reduce the difference in longitudinal position between the free end 4 and the position indicator 6.
  • the permanent magnet 10 When the magnetic element 8 and the permanent magnet 10 are sufficiently close to each other, which will be the case the position indicator 6 and the bottom element 4 are substantially in the same longitudinal position, the permanent magnet 10 will attract the magnetic element 8 such as to form a magnetic connection.
  • the metallic element 8 and the permanent magnet 10 are adapted to interact, and particularly to take up a position in alignment with each other, when the bottom element 4 and the position indicator 6 are located in substantially the same longitudinal position. The result is that in any further movement of the bottom element 4 the position indicator 6 will follow the bottom element 4 due to the magnetic force between the metallic element 8 and the permanent magnet 10. So when the screening device is operated by e.g. a remote control, or an automated system operating on timing opening or sensor the position indicator 6 will follow the bottom element 4 and remain aligned.
  • the magnetic connection between the bottom element 4 and the position indicator 6 will cause the position indicator to follow the longitudinal position of the bottom element as a slave.
  • the user may also manually control the position of the screen 5 and release the position indicator 6 from the bottom element 4 by manually sliding the position indicator and the manual force thereby overcoming the magnetic force and disengaging the magnetic connection.
  • a signal is triggered and sent from the sensor element 7, 9 to the electric drive or to a control device of the electric drive means.
  • the signal from the sensor elements 7, 9 may cause the electrical drive to reverse its direction of operation to move the bottom element 4 in a direction opposite to the initial direction of movement in case the bottom element 4 has been moved too far, or it may cause the electric drive to stop when the desired positon has been reached, i.e. When the bottom element 4 and the position indicator 6 have substantially the same longitudinal position.
  • the at least one sensor element is configured to register the direction of movement that ended the longitudinal alignment of the position indicator 6 and bottom element 4. So the at least one sensor element can register if the position indicator is moved above the bottom element or below the bottom element. This may for example be done by plural sensors or by employing a first signal when the position indicator is moved above the bottom element and a second signal when the position indicator is moved below the bottom element. For example some sensors may be direction sensitive.
  • the screening device without the two sensor elements 7, 9 as well as the screen device in which the free end component and/or the position indicator component has been omitted are also feasible. In the latter case the two sensor elements 7, 9 may be used to detect whether the desired position has been reached. In the screening device where both the bottom element component and the position detector component have been omitted by sensing the presence of the position detector 6, and in another embodiment where only the bottom element component has been omitted by sensing the presence of the position detector component.

  • bottom element positioning device comprises no sensor or detector
  • the bottom element positioning device comprises no sensor or detector
  • the side rail 2 comprises a magnetic material strip 11 and the position detector 6 is provided with a permanent magnet so that the position detector 6 may be mounted on the side rail 2 by a magnetic attractive force between the magnetic material strip 11 and the permanent magnet.
