ACTUATION UNIT FOR VENETIAN BLINDS OR THE LIKE

摘要

An actuation unit for light-blocking means, such as Venetian blinds or the like, which are accommodated in a double-glazing unit or are fixed to a window and are suitable to be moved from a fully packed or rolled-up condition to an opened-out condition and viceversa. The unit comprises a magnetic kinematic coupling device which is associated with means for generating a rotary motion and with kinematic systems for moving the blocking means; the device is constituted by at least one first permanent magnet which is connected so as to rotate with the axis of the motor means, and at least one second permanent magnet, whose polarization is parallel and similar to that of the first magnet and which is suitable to rotate in relation to the rotation of the central magnet by virtue of the closure of radial field lines.
