Abstract:
An actuation unit connected with light blocking means movably arranged between a rolled-up condition and an opened-out condition in a hermetic air space of a double-glazing unit having a pair of glass panes between which said hermetic air space is formed, said actuation unit comprising a magnetic kinematic coupling device connected with means for generating a rotary motion and with kinematic systems for moving said light blocking means, said magnetic kinematic coupling device comprising at least one first permanent magnet which is arranged outside said hermetic air space and which is connected in rotation with a shaft of said means for generating a rotary motion, and at least one second permanent magnet arranged adjacent said first permanent magnet and having a polarization extending parallel to the polarization extension of said first magnet such that said second permanent magnet rotates in relation to the rotation of said first magnet in response to a closure of radial field lines, said at least one second permanent magnet being connected to a shaft of said kinematic systems for moving said light blocking means arranged inside said hermetic air space for rotation of said shaft of said kinematic systems for moving said light blocking means dependent upon the rotation of said at least one first permanent magnet.
