Definitions

  • the present invention relates to a window covering device, comprising a window cover, a motor arrangement and a wand, and to a wand for a window covering device.
  • One problem with prior art window covering devices powered by solar cells is that the electrical connection between the solar cells and the motor can be a challenge and/or not visually attractive, e.g. if electrical threads or cords needs to be included in the fabric, or if a loose cable is needed between the solar cells and the motor.
  • Another problem with prior art window covering devices powered by solar cells is that the solar cells may affect and limit the visual design of the blinds or of the window.
  • An object of the present invention is therefore to provide a wand for and a window covering device which solves the drawbacks of the prior art.
  • the present invention relates to a window covering device comprising a window cover, a motor arrangement and a wand, wherein the motor arrangement comprises an electrical motor, arranged to actuate the window cover, power storage means and driver electronic means arranged to control actuation of the electrical motor and charging of the power storage means, wherein the wand is arranged to be hanging in the window covering device by means of a mechanical wand connection means, wherein solar cells are arranged at the wand, wherein the wand is arranged to be in electrical connection with the motor arrangement by means of an electrical wand connection means and wherein the motor arrangement is placed inside a tube or a headrail of the window covering device.
  • the motor arrangement comprises an electrical motor, arranged to actuate the window cover, power storage means and driver electronic means arranged to control actuation of the electrical motor and charging of the power storage means
  • the wand is arranged to be hanging in the window covering device by means of a mechanical wand connection means
  • solar cells are arranged at the wand
  • a wand is known in the field of window covering devices as a stick or rod hanging at the side of the window cover and being used for controlling e.g. the position of horizontal slats in Venetian blinds by turning the wand.
  • a wand is placed at curtains and being used for manually pulling the curtains without having to touch the fabric of the curtain. Therefore a wand hanging at a window covering device will be perceived as a device for controlling the position of the blind and thus will not be seen as negatively affecting the visual appearance or impression of the blind.
  • the wand is provided with solar cells used for charging the power storage means, which could be e.g. a battery or a capacitor, for powering the electrical motor of the window covering device.
  • the wand is elongated and can have any suitable cross sectional shape such as circular, triangular, rectangular, octagonal, etc.
  • the wand could be flat having two major sides where one or both sides are covered with solar cells.
  • the solar cells are including means for converting solar energy to electrical energy.
  • the solar cells could be a rigid solar cell based on silicon technology such as Sunpower silicon cells in a PET and ETFE enclosure, or a thin film solar cell technology such as amorphous silicon or copper indium gallium selenide, as for example the custom flex module from mia2ole.
  • An advantage with providing solar cells on a wand is, as explained above, that the wand will in normal use be arranged sufficiently close to a window and therefore be exposed to enough light to power the window covering device. Moreover, since the wand is hung in the window covering device it requires no or very little installation efforts. In addition, and since the wand is hung in the window covering device by means of mechanical wand connection means, it may be possible to use the wand for mechanically regulating the position of the window cover provided that a suitable mechanism for mechanically regulating the window cover is included and connected to the mechanical wand connection means.
  • Such mechanism could be a mechanism for tilting the slats of a Venetian blinds, or for starting and stopping the motor by pulling the wand, or winding and unwinding fabric in a roller blind, etc.
  • Window cover could be e.g. a roller blind, honeycomb blind, Venetian blind, roman blind, curtain, panels etc.
  • actuating the window cover could be moving the roller blind fabric on a tube, or moving honeycomb blind or Venetian blinds up and down or moving the position of horizontal slats of blinds, or for curtain and panel options actuating could be to move in a horizontal direction.
  • the solar cells are integrated in the wand.
  • the solar cells could be integrated inside the wand or being integrated in the wand on the external side of the wand, or a combination.
  • the wand has a handle portion for a user to pull and/or turn the wand to control the position or motion of the window cover.
  • the handle portion can be the lower portion of the wand.
  • the handle portion can be shaped to direct the user to grab the handle portion e.g. by being comprised of a material with some friction/tactile means.
  • the handle portion can be the entire wand thereby the user may grab the wand at any suitable position of the wand.
  • the mechanical wand connection means and the electrical wand connection means are arranged at the upper end portion of the wand, when the wand is arranged hanging in the at the window covering device, and the handle portion is arranged at the lower end portion of the wand.
  • the wand comprises a tube having at least one transparent portion and the solar cells are arranged inside the tube at the transparent portion.
  • the tube can provide proper protection for the solar cells.
  • the tube could be transparent at one or several portions of the tube or the entire tube can be transparent. Portions that are not transparent may be covered by another surface material, such as a veneer or other material for a design purpose.
  • the solar cells comprise a solar cell film arranged inside the transparent tube.
  • a solar cell film arranged inside a tube may be a cheap way or realizing the invention.
  • the film can be flexible and inserted into the tube.
  • the electrical wand connection means and the mechanical wand connection means are arranged in a common connection structure. Thereby it may be easier for users since less assembly is needed and in addition it may give a nice look.
  • the wand is elongated and having a total length of least 30 cm, preferably at least 40 cm. A certain length may also be required in order to ensure large enough surface area to be covered by solar cells.
  • the wand may be easily reachable for the user which might require a certain length.
  • the wand may have a width of between 0.3 cm - 5 cm, preferably between 1 cm - 3 cm. Since the wand is an elongated stick the width is referring to the diameter of the wand if the wand is a rod with a circular cross section, or the corresponding cross sectional measure for a wand having another shape than a rod with circular circumference.
  • the mechanical wand connection means and the electrical wand connection means are detachable from the window covering device allowing the wand to be detachable from the window covering device.
  • a detachable wand could be used and/or sold as a separate article.
  • the window covering device comprises wireless control means for controlling the motion of the window cover wirelessly.
  • the wand, or any other suitable portion of the window covering device can include wireless control means such that the blind can be operated wirelessly. For instance zigbee or any other suitable protocol can be used for controlling the window covering device.
  • the wand may then be used for the sole purpose of charging the power source of the window covering device, or it may in addition be used for controlling the motion of the window cover.
  • the window covering device may comprise solar cell driver electronics for controlling transport of electricity from the solar cells to the power storage means.
  • the present invention relates to wand of a window covering device, wherein the wand comprises solar cells, wherein the wand is arranged to be in electrical connection with a motor arrangement placed inside a tube or headrail of the window covering device by means of an electrical wand connection means and wherein the wand is arranged to be mechanical connection with the window covering device by means of a mechanical wand connection means allowing the wand to hang in the window covering device.
