Window construction
The present invention refers to a window construction, particularly to be used in a train, vehicle, car, helicopter, aircraft or building, which comprises a laminated window glazing having electrically switchable layer means arranged in a laminate, and controlling means being coupled to the switchable layer means for controlling the sunlight transparency of the switchable layer means.
1. Window construction, particularly to be used in a train, vehicle, car, helicopter, aircraft or building, which comprises a laminated window glazing having electrically switchable layer means arranged in a laminate, and controlling means being coupled to the switchable layer means for controlling the sunlight transparency of the switchable layer means, wherein the controlling means comprises at least a display for indicating a presently adjusted or switched status of transparency of the window glazing or of the switchable layer means, and/or at least a switch to be operated by a person or passenger for controlling the transparency of the window glazing or switchable layer means,
wherein the controlling means comprises a touch sensitive system or touch sensitive panel for realizing the switch or a touch screen for realizing the switch and the display, and wherein the controlling means comprises a controlling unit or interface electrically coupled to the touch sensitive panel or system or touch screen, the switchable layer means of the window glazing, and to a voltage supply,
the window construction comprising a first wiring for coupling the touch sensitive panel or system or the touch screen to the controlling unit, wherein the first wiring is arranged on or within the window glazing, and/or a second wiring for coupling the controlling unit to the switchable layer means, wherein the second wiring is arranged on or within the window glazing.
2. Window construction according to claim 1 , characterized in that the controlling means is arranged at least partly on or within the window glazing.
3. Window construction according to claim 1 , characterized in that the the touch sensitive panel or system or touch screen is accessible inside of a vehicle or building or passenger compartment.
4. Window construction according to claim 3 , characterized in that the touch sensitive panel or system or touch screen is arranged on or in the window glazing.
5. Window construction according to claim 3 , characterized in that the switchable layer means and the touch sensitive panel, touch sensitive system, or touch screen are in the same layer plane.
6. Window construction according to claim 1 , characterized in that the controlling unit is arranged on or within the window glazing.
7. Window construction according to claim 1 , characterized in that the window glazing comprises a wiring layer comprising the first and second wirings.
8. Window construction according to claim 1 , characterized in that the laminated window glazing comprises panes, made of glass or plastic selected from polycarbonate, PMMA or hard polyurethane, and interlayers made of an adhesive foil selected from a polyvinylbutyral or polyurethane or EVA foil, and the electrical switchable layer means comprises at least a first electrode layer, a second electrode layer, and an electrochromic layer arranged between the first and second electrode layers, and wherein the first electrode layer is portioned into a plurality of electrode fields corresponding to respective darkening fields or segments which are separately and independently controllable electrically by the controlling means, and that the second electrode layer is the common electrode coupled to electrical reference potential.
9. Window construction according to claim 8 , characterized in that the electrode fields and corresponding darkening fields are formed in stripes vertically or horizontally arranged.
10. Window construction according to claim 1 , characterized in that a controlling unit of the controlling means is installed in a free space between panes of the window glazing.
11. Window construction according to claim 1 , characterized in that the window glazing comprises an insulating gap or insulating space like in an insulating window which is defined by two parallel panes made of glass or plastic, and an insulating spacer profile circumferentially extending in the form of a frame between the panes.
12. Window construction, particularly to be used in a train, vehicle, car, helicopter, aircraft or building, which comprises a laminated window glazing having electrically switchable layer means arranged in a laminate, and controlling means being coupled to the switchable layer means for controlling the sunlight transparency of the switchable layer means,
wherein the controlling means comprises at least one display for indicating a presently adjusted or switched status of transparency of the window glazing or of the switchable layer means, and/or at least one switch to be operated by a person or passenger for controlling the transparency of the window glazing or switchable layer means, and
wherein the controlling means comprises a touch sensitive system or touch sensitive panel for realizing the switch and the display, the touch sensitive panel or system or touch screen is accessible inside of a vehicle or building or passenger compartment,
wherein the touch sensitive panel or system or touch screen comprises a printed structure or circuit.
