Definitions

  • the present invention relates to blinds, roller shutters and other assemblies in which the flexible closing member is wound on a drum which is rotated by an electric motor and with which is associated a device capable of ensuring its automatic braking in order to immobilize the aforementioned member as soon as said electric motor is no longer supplied with power.
  • One of the aims of the invention is the production of an automatic braking device of the aforementioned type which, despite a simplified mechanical construction compared to the usual technique, is remarkably effective with regard to braking force.
  • Another object of the invention is to provide the device with an unlocking system which is capable of being easily operated by hand in the event of a failure of the supply current.
  • the device according to the invention is characterized in that it comprises a braking disc which is angularly retained in the fixed frame while being free to move axially therein and against the opposite faces from which two plates are applied turning one of which is carried by a clean cylinder head, by magnetic attraction, to move axially against elastic means as soon as the winding of the electric motor is excited, while the other receives, through a suitably intermediate bearing arranged, the action of the manual control mechanism.
  • a yoke 7 made of magnetic metal, the end of which faces towards the rotor 5 is hollowed out by a cylindrical depression or bowl 7 a inside which comes engaging an annular projection 5 is provided on said rotor.
  • a spring 8 which surrounds the shaft 6 and which tends to elastically separate said cylinder head from the rotor.
  • this cylinder head 7 comprises a plate 7 b which the spring 8 tends to apply against a disc 9 made of a material with a high coefficient of friction, which disc is angularly immobilized by at least one longitudinal key 10 a secured to a fixed spacer 10 attached to the inside of the frame 2.
  • the disc 9 is in fact pinched between the aforementioned plate 7b and an opposite plate 11 suitably immobilized on the shaft 6, for example using 'a pin 12. It will be observed that the plate 11 is freely traversed by longitudinal fingers 13 fixed inside blind housings formed in the cylinder head 7.
  • the end of this lever 17 which is turned towards the inside of the frame 2 is applied against the central part of a bar 19 provided with pushers 20 slidably mounted in the perforations of the spacer 10; springs 21, carried by the pushers 20 and bearing against the spacer 10, tend to push the bar 19 against the rocking lever 17.
  • the pushers 20 pass through the spacer 10 in order to bear against the outer ring of a ball bearing 22, of the deep groove type, the inner ring of which slides and rotates on the hub of the plate 11 linked to the shaft 6. It is therefore conceivable that the operation of the rocking lever 17 to using the cable 18 (whose free end is accessible outside the frame 2) causes, by pressing the pushers 20 against the bearing 22, the axial displacement of the latter which in turn repels the fingers 13 and the cylinder head 7 against spring 8.
