A MULTI LAYER PANE UNIT WITH A BUILT-IN ADJUSTABLE LIGHT SCREENING DEVICE AND AN INSULATION WINDOW HAVING SUCH A PANE UNIT
In a multi-layer glass unit having a built-in, adjustable screening device a rotatable driving device for the screening device is arranged in the edge sealed space between the glass layers along one of the side edges and may be coupled to an external drive unit by means of a rotatable magnetic coupling comprising an internal magnet member in driving connection with the rotatable driving device and an external magnet member positioned outside the space and being in driving connection with the external drive unit. The magnet members are arranged with poles facing each other on respective sides of an interface section of the airtight sealed space, which has the form of a comparatively thin wall part in a member forming part of the edge sealing and constituting a bearing for the external magnet member.
