Definitions

  • the subject of the present invention is a drive device for a Venetian blind comprising a box open downwards in which is mounted a motor driving, by means of a speed reducer, a drive shaft on which are mounted two pulleys located near the ends of the box and at least one intermediate pulley, pulleys intended for winding the laces of the awning and for opening its blades, each of these pulleys being rotatably mounted in a cradle.
  • the motor equipped with its reducer, and rigidly fixed to the bottom of the box, at an intermediate point between the ends of the box and has two drive shafts on which are mounted the pulleys whose cradles are rigidly fixed to the walls of the box by screws.
  • the motor equipped with its reducer, and rigidly fixed to the bottom of the box, at an intermediate point between the ends of the box and has two drive shafts on which are mounted the pulleys whose cradles are rigidly fixed to the walls of the box by screws.
  • Alignment faults result in vibrations which are transmitted by all the elements to the box, giving rise to significant noise.
  • the object of the present invention is to provide a drive device for a Venetian blind obviating the above-mentioned drawbacks, that is to say silent, easy to make and to install.
  • the drive device is characterized in that the motor is a tubular motor mounted inside said drive shaft and whose head is rigidly connected to the box, that said drive shaft is supported at its ends and at least the intermediate cradle is mounted floating in the box.
  • the intermediate cradle respectively the intermediate cradles, being mounted floating in the box, the axis of their pulley is automatically aligned with the axis of the drive shaft.
  • the use of a tubular motor makes it possible to have a single drive shaft of large cross section. These features help suppress vibrations and make the drive unit quiet.
  • the device shown in Figures 1 and 2 comprises a metal box 1 formed of a rectangular profile open downwards and two end flanges 2 and 3.
  • the drive shaft 4 is tubular and of hexagonal section. Inside the shaft 4 is mounted a tubular motor 5 associated with a reduction gear, motor whose head 6 is rigidly fixed to the flange 3, while the end 7 of the drive shaft 4 is journalled in the flange 2 which serves as a bearing.
  • the drive shaft 4 passes through two end pulleys 8 and 9 and an intermediate pulley 10 which are of course integral in rotation with the shaft 4.
  • Each of these pulleys has a central groove for winding the laces of the blind Venetian and two lateral grooves for driving scales for the orientation of the blind slats.
  • the pulleys 8, 9 and 10 are rotatably mounted respectively in a cradle 11, 12 and 13 shown diagrammatically. These cradles are mounted floating in the box 1 in the vertical direction. For this purpose, each cradle has two lateral tenons 14 and 15 engaged with a vertical clearance in cutouts 16 and 17 of the box 1.
  • the position of the drive shaft 4 is determined by the end flanges 2 and 3.
  • the cradles 11, 12 and 13 are floating, the pulleys 8, 9 and 10 can automatically align with the shaft training.
  • This embodiment is advantageous in that it allows the motorized drive shaft to be easily attached. The blind can therefore be pre-assembled and even pre-installed.
  • the second embodiment differs from the first embodiment in that the drive shaft 4 is supported by the end cradles 11 and 12 instead of being supported by the end flanges 18 and 19, these flanges can therefore be made lighter and fixed to the box by simple interlocking.
  • the cradles 11 and 12 are therefore rigidly fixed to the side walls of the box 1, preferably by interlocking without a set of split pins 20 and 21, the two arms of which come automatically hooked in known manner on the external face of the box.
  • the intermediate cradle 13 is however mounted floating as in the first embodiment. The same would be the case for other intermediate cradles.
  • the motor head 6 is rigidly fixed to an intermediate support 22 which is rigidly fixed to the cradle 12.
  • the end 7 of the drive shaft is, in a similar manner, journalled in an intermediate support 23 rigidly fixed to the cradle 11 .
  • the intermediate support 22 pre feels a shape adapted to the head 6 of the engine and partially enveloping this head.
  • the head 6 of the engine is fixed to the part 22 by two screws such as the screw 24, the support 22 itself being fixed to the cradle 12 by three ears such as 25 and 26 provided with a hole through which they are engaged. pins 27 of the cradle 12 on which they are held by clips.
