Abstract
Motorized actuation device for a Venetian blind or the like placed inside an insulating glass frame including a first magnet, arranged inside the insulating glass frame and directly connected to the respective actuation system, and a second external magnet, the second magnet being associated with the translatory part of a kinematic system for converting the rotary motion into a translatory motion, and the kinematic system being connected to an actuation gearmotor.

Motorized actuation device for a Venetian blind (10) placed inside an insulating glass frame (13), comprising a first magnet (19), arranged inside the insulating glass frame and directly connected to a respective actuation system (16,18,20,21) for manipulating the blind, and a second external magnet (27), said second magnet being associated with a translatory part (26) of a kinematic system (23) for converting rotary motion into a translatory motion, and wherein said kinematic system is a screw-and-nut kinematic system (23) in which a worm screw (24) is rigidly coupled to an output shaft of an electric gearmotor (25) and a nut (26) is mounted on said screw (24) and is thereby slidingly retained with respect to the insulating glass frame (13).
In combination, an insulating glass frame (13), a Venetian blind (10) placed inside said insulating glass frame (13), a motorized actuation device for said Venetian blind (10), a venetian blind actuation system (16, 18, 20, 21), a first magnet (19) arranged inside said insulating glass frame and directly connected to said Venetian blind actuation system (16,18,20,21), a second external magnet (27), a kinematic system (23) for converting rotary motion into translatory motion, and an actuation gearmotor (25), said kinematic system (23) being connected to said actuation gearmotor (25);
- wherein said gearmotor (25) has an output shaft, and wherein said kinematic system (23) comprises a worm screw (24) and a nut (26), said worm screw (24) being rigidly coupled to said output shaft of said electric gearmotor (25), said nut (26) threadedly engaging said worm screw and being retained slideably with respect to said insulating glass frame (13) said second external magnet being connected to said nut (26).
