Definitions

  • the present invention will find application in the field of building closure systems. It will find a particular interest in the field of roller shutters whose apron is intended to be deployed in an inclined position, even flat, in the case of shutters for windows of roofs, verandas or similar.
  • a roller shutter comprises, in a usual manner, an apron composed of a juxtaposition of blades at least hinged together capable of being deployed from a winding tube, knowing that slides provide lateral guidance of this deck to ensure its deployment in front of a door, window or the like.
  • a drive mechanism acts on the winding tube to, depending on the direction of rotation communicated to the latter, control the deployment or folding of the deck.
  • the direction of rotation communicated to the winding tube has the effect of exerting traction on the deck which largely compensate for the forces resulting from the friction of the latter, in particular at the level of the lateral guidance of the blades in the wings.
  • the apron deploys, usually, under the effect of its own weight during the unwind command. If, in a vertical position, the weight of the blades is sufficient to compensate for the friction forces to which reference has been made above, at the slightest inclination imparted to this roller shutter, these friction forces increase considerably and it is no longer possible to ensure the deployment of the deck by gravity. In sum, in this case, it is advisable to push the apron behind the scenes.
  • a first solution consisted in conferring a driving function, as the case may be, on the unwinding shaft or the winding tube, this as a function of the direction of movement to be communicated to the deck.
  • the unwinding axis is driven, motorized or manual, whereas the rotation imparted to the winding tube through the deployment of the deck results in the tensioning of a spring of torsion.
  • this spring causes, in turn, the winding tube. Note that, if for this lift of the deck is acting on the manual or motorized means controlling the rotation of the unwinding shaft, this action has the sole function of releasing that of the spring for the drive of the winding tube.
  • a torsion spring is connected at one of its ends to the winding tube, while the opposite end of this torsion spring is integral with a drive shaft connected by transmission means to the winding tube. unwinding axis.
  • the torsion spring can store a compressive force such that, at the time of release, the roller shutter, in particular the apron, can be damaged.
  • the present invention attempts to address the problems of these known solutions.
  • the drive device makes it possible to preserve a mechanical transmission, whether manual or motorized, between the unwinding shaft and the winding tube, this through a differential allowing to ensure a variable transmission ratio.
  • this variable transmission ratio results from the transformation of a control in rotation both in a rotation and an axially variable displacement of a drive wheel acting on the winding tube.
  • resilient return means contribute to the axial displacement of said output wheel.
  • the input rotation control is provided through an axis in the form of a worm on which is mounted the output wheel defined as a nut integral in rotation of the winding tube while by being movable axially on the axis that defines the worm.
  • the nut that defines the drive wheel and output move axially in one direction or the other, either under the braking effect of the winding tube, resulting in the stressing of elastic return means, or by acceleration of the winding tube resulting from the return of the energy of these elastic return means in the preferred form of a compression spring.
  • the advantages deriving from the present invention consist in that the retransmission, at variable speed, of the drive of the unwinding shaft to the winding tube takes place through a direct mechanical connection without the interposition of a spring knowing that the elastic return means used here do not provide a retransmission of movement, but allow, through the energy they are able to accumulate according to the direction of rotation communicated, to ensure, if necessary , a play catch that can present this transmission mechanism through a differential speed.
  • the present invention is in the field of roller shutters 1, in particular whose apron 2 is provided capable of being deployed in a flat position, or more or less inclined, as is the case of roller shutters for roof windows, verandas or similar 3.
  • the apron 2 of such a shutter 1 is composed of a juxtaposition of blades 4 at least hinged together and capable of being deployed from a winding tube knowing that the slides 6 provide the lateral guidance of the apron 2 to guarantee its deployment at the front of the window 3 or the like.

  • Drive means 9, more particularly in the form of an electric motor, are provided for rotating the unwinding shaft 8, while transmission means 10, connecting the unwinding shaft 8 to the winding tube 5 are able to train the latter in a variable transmission ratio.
  • these transmission means 10 comprise an integrated differential device 11 comprising an input shaft 12 on which is mounted in rotation an output drive wheel 13 which is integral in rotation the winding tube 5, means 14 being adapted to allow the transformation of the rotation of the input shaft 12 into a rotation and / or an axial linear displacement of the output drive wheel 13, to allow a differential angular rotation of the input shaft 12 with respect to the output drive wheel 13.
  • This differential speed makes it possible to transmit to the winding tube 5 a variable rotational speed with respect to the driving speed communicated by the means 9 on the unwinding axis 8.
  • a suitable belt transmission or gearing can act on the input shaft 12 of the differential device 11.
  • a pulley 15 around which is wound a belt 16, coming, moreover, to be wound at least around a second pulley 17 fast with rotation of the unwinding axis 8 on which the drive means 9 act.
  • the pulley 17 is not necessarily mounted on the end of the unwinding shaft 8, knowing that it can be directly dependent of said drive means 9.
  • This transmission can be defined by a gear adapted through which it is also possible to obtain a reversal of the direction of rotation between the unwinding shaft 8 and the winding tube 5. This reversal may be necessary depending on the passage of the deck 2 above or below the unwinding axis 8 and / or the winding direction around the winding tube 5.
  • the means 14, allowing through the input shaft 12 to communicate to the output drive wheel 13 a rotation and / or an axial displacement, substantially consist of an input shaft 12 in the form of a screw endless having a helical thread 18 with which is able to cooperate said output drive wheel 13 designed in the form of a nut.
  • this output drive wheel 13 may have, internally to its bore, a tapping or, as illustrated in FIG. 2, sections of ribs 19 designed adapted to engage the helical thread 18.
  • the device 7, according to the invention further comprises elastic compression biasing means 20 capable of accumulating energy, in particular during the winding control phase of the deck 2, to be able to restore it in phase deployment of said deck 2, or vice versa.
  • elastic return means 20 allow, by repelling in axial translation the output drive wheel 13 on the worm defined by the output shaft 12, to compensate the differential of when at the beginning of deployment, the initial section of the winding tube 5 requires the latter to be driven at a lower angular velocity at the angular velocity communicated to it by the input shaft 12 on which the transmission means 10.
  • the elastic return means 20 are in the form of a compression spring 21 interposed between the output drive wheel 13 and a stop plane 21A.
  • this abutment plane 21A can be located inside the winding tube 5 in which, moreover, the compression spring extends. 21 and the output drive wheel 13. As illustrated, it can be rotatably mounted within the winding tube 5 while being movable in translation.
  • this winding tube 5 may be formed one or more grooves, or ribs, axial 22 with which one or are able to cooperate one or more ribs, respectively grooves 23, that includes periphery and according to generators, the output drive wheel 13.
  • the output drive wheel 13 and the compression spring 21 take place in a transmission cage 5A, located on one side of a support cheek J and in connection with each other. , for transmission by rotation, with the winding tube 5.
  • a transmission cage 5A located on one side of a support cheek J and in connection with each other. , for transmission by rotation, with the winding tube 5.

  • this transmission cage 5A may be formed one or more grooves, or ribs, axial with the one or which is able to cooperate one or more ribs, respectively grooves, that includes periphery and generators, the output drive wheel 13.
  • the transmission by belt or gear acts on the input shaft 12 through an epicyclic gear train 39.
  • a sun gear carrier 40 engaged, through planetary gear 41, on the one hand, with a driving ring defined by the pulley 15, and, on the other hand, with a drive shaft acting, directly or through a torque limiting device 24, on the winding tube 5.
  • a transmission cage 5A in which is mounted, integral in rotation and free in translation, said output drive wheel 13, designed in the form of a nut and cooperating, through at least a helical thread 18, with the input shaft 12 on which this wheel 13 is mounted.
  • the device 7, comprises resilient compression biasing means 20 capable of accumulating energy, in particular during the winding control phase of the deck 2, to be able to restore it in phase. deployment of said deck 2, or vice versa.
  • these elastic return means 20 allow, by repelling in axial translation the output drive wheel 13 on the worm defined by the output shaft 12, to compensate the differential of when at the beginning of deployment, the initial section of the winding tube 5 requires the latter to be driven at a lower angular velocity at the angular velocity communicated to it by the input shaft 12 on which the transmission means 10.
  • the elastic return means 20 are in the form of a compression spring 21 interposed between the output drive wheel 13 and a stop plane 21A formed in the transmission cage 5A.
  • the motor housed in the unwinding tube 8 and to which it communicates a constant speed of rotation, drives the pulley 17 and, through the belt 16, the pulley 15 in form drive crown.
  • This movement is accompanied by the compression of the spring 21 whose energy can be restored during a reverse rotation control deployment.
  • the energy accumulated by the spring 21 allows, in this case, to accelerate the output wheel 13 and thus the speed of rotation of the winding tube 5
  • the transmission means 10 comprise a torque limiter 24 to ensure their disengagement with respect to the winding tube 5 in case of blockage.
  • this torque limiter 24 is interposed between the pulley 15 and the input shaft 12 of the differential device 7.

These teeth, with inclined teeth, are caused to cooperate through the maintenance of the disk 25 against the pulley 15 under the action of resilient return means 28, shown here in the form of a conical spring washer, called belleville.
  • this washer provides resistance to the axial displacement of the disc 25 relative to said pulley 15 which allows the torque limiter 24 declutch disengaging beyond a certain torque resistant.
  • the torque limiter 24 ensures the connection, for rotational transmission, between the transmission cage 5A and the winding tube 5.

  • they comprise a set screw 32 which is able to control in rotation, directly or indirectly, the winding tube 5 and / or the transmission cage 5A. It is understood that by acting in rotation on any one of these elements, while the transmission means 10 are themselves stationary, the resulting angular velocity differential can be absorbed only when through an axial component displacement of the output drive wheel 13 on the input shaft 12. Depending on the direction of rotation communicated by the adjusting screw, this displacement leads to prestress the spring of compression 21.
  • the adjusting screw 32 acts on a peripheral toothing 33 carried by the flange 15A integral with the winding tube 5.
  • the disc 25A could be defined in the manner of a crown and carry a toothing with which such a set screw 32 could cooperate.
