Definitions

  • the present invention concerns a multi-pane glazing unit.
  • GB 2 415 989 A discloses a glazing unit with a varying gap width according to the preamble of claim 1.
  • the object of the invention is to solve or reduce the problem of the radio frequency dependent signal attenuation of multi-pane glazing units.
  • a glazing unit with a gap width between a first glass pane and a second glass pane which varies between a minimum gap width and a maximum gap width allows to create a glazing unit with a plurality of gap widths.
  • the minimum gap width is 6 mm and the maximum gap width is 24 mm.
  • the varying gap width allows to reduce the signal attenuation for certain frequency bands significantly. This could be further used to design the glazing unit such as to have a certain desired radio frequency transmission function. For example, in some applications, it could be desirable to rather attenuate a first frequency band with respect to a radio signal in a second frequency band.
  • the invention refers to a multi-pane glazing unit.
  • Multi-pane glazing units are also called insulating glass or insulating glass unit.
  • the multi-glazing unit can comprise a direction for mounting the multi-glazing unit in the sense that the multi-glazing unit has an external side and/or an internal side.
  • the multi-glazing unit could comprise an external side which is configured to be arranged to point to the external side of a space and an internal side which is configured to be arranged to point to the inside of a space.
  • the space is for example, a building space, like a room, a hall, etc..
  • the space can however also be a vehicle, like a car, truck, airplane, train, etc..
  • the space can be any other space.
  • the space is preferably closed or closable to the outside.
  • the space can however also be semi-closed or even open.
  • the external side could be defined e.g., by a functional coating which acts different compared to the internal side, e.g., a sun protection or a silvering. If there is no difference between a first side and a second side of the glazing unit, the external side shall be the first side and the internal side the second side without any limitation of the invention.

  • the first glass pane 1 has the non-plane form, while the second glass pane 2 has a plane form (parallel to the glazing plane).
  • the first glass pane 1 (and the second glass pane 2) has preferably a constant thickness.
  • the embodiments with glass panes with varying thicknesses and with non-plane forms have however the disadvantage that they require the production of special glass panes.
  • the change in the thickness of the glass pane increases the weight (for larger thicknesses) or reduces the insulation effects (for smaller thicknesses).
  • the second glass pane 2 could be arranged between the first glass pane 1 and the third glass pane and (only) (the first side, the second side and/or the pane plane of) the second glass pane 2 could be arranged at said angle 8 (while the third glass pane 3 is parallel to the second glass pane 2).
  • the gap width 7 between the second glass pane 2 and the third glass pane 3 is constant. Such an embodiment is shown in Fig. 4 .
  • the first and third glass pane 1, 3 are parallel to the glazing plane, while the second glass pane 2 is arranged at an angle 8 to the glazing pane, the first glass pane 1 or the third glass pane 3.
  • the second side of the first glass pane 1 and a second side of the third glass pane would be parallel to the glazing unit plane.

  • An embodiment of a triple-pane glazing unit with a gap width varying over glazing unit plane between a minimum gap width 4 and a maximum gap width 5 allows to significantly reduce said transmission drops.
  • the thick black transmission line drawn in Fig. 11 would be the theoretical minimum transmission line for an embodiment as shown in Fig. 1 with the gap width varying between the minimum gap width 4 of 6 mm and the maximum gap width 5 of 24 mm.

  • One or more or all of the at least two glass panes may have a special coating e.g., for an increased thermal insulation.
  • a coating is not covering the whole pane surface but divided into (small) areas in order to allow radio signals to go through.
  • the gap width between first glass pane 1 and the second glass pane 2 varies.
  • the minimum gap width is 6 mm and the maximum gap width is 24 mm.
