Definitions

  • the present invention relates to a device for maneuvering the door leaf shaft of a roller shutter. It relates more particularly to a cord winch system equipped with a brake means on the apron-carrying shaft, an active declutching means when there is too much torque on the shaft, a system limit switch which acts on the winch when the bulkhead is in the low position.
  • Known cord winch systems having a coupling system between the driving part (winch) and the receiving part (support shaft of the roller shutter deck) with ratchets; generally this system works only in one direction and is conditioned by the presence of a resistant torque on the receiving part.
  • the ratchet system authorizes the raising of the apron and leaves the descent of the shutter free, the latter being only braked by the presence of a brake, disposed in a position very set back from the winch part, which considerably increases the overall dimensions.
  • these devices do not include an end-of-travel system, which, thanks to mechanical stops, makes it possible on the one hand to limit the low travel of the deck, and on the other hand, blocks the deck in a state which avoids any intrusion.
  • the present invention therefore aims to overcome these drawbacks by proposing a cord winch having a declutching mechanism active in both directions of rotation, which combines both a limit switch and braking system very integrated in the mechanism of the winch, for a better compactness of the whole.
  • the cord winch is characterized in that it comprises a shaft integral with a pulley, receiving at its periphery a crown, trapping the cord of the winch and being able to disengage with respect to said pulley, the peripheral part of the pulley further comprising a belt provided with inclined walls, these canted surfaces generating areas of friction and sliding for the crown being able to move in a relative movement of rotation relative to said pulley, said shaft being moreover connected by the one of its ends to a gear train forming a reducer between the winch part and the solid part of the shaft of the roller shutter deck, each of the parts being connected together by an irreversibility brake system acting on a solid lining a casing surrounding said winch, said gear train being further provided with a limit switch system for limiting the movement of the table er of the roller shutter in the low position.
  • the cord winch according to the invention essentially comprises a pulley 1 integral in its center with a cylindrical portion 2, stopped in translation at one of its ends, by a casing 3 disposed around said pulley 1.
  • the peripheral part 4 of the latter 1 comprises a belt 5 provided with inclined walls 6, forming a profile in ⁇ whose angle ⁇ relative to the horizontal is between 5 and 45 ° and preferably chosen to be close to 20 °
  • These surfaces 6 on a slope generate friction and sliding zones for a crown 7 which can move in a relative movement of rotation relative to said pulley 1.
  • the crown 7 mainly comprises two flanges 8, 9, generally made of plastic material and obtained by molding, the latter are made integral with a friction ring 10, one of the walls 11 of which is in contact with the surfaces 6 in cant, by a plurality of metal washers 12 with variable flexibility.
  • Said ring 10 is produced from an assembly of cups 13, preferably made of plastic, in particular polypropylene, and the internal wall of which has a profile similar to the cant surface 6 present on the crown 7 of the axial part 2 central.
  • the metal washers 12 are kept outside their elastic deformation zone, within an zone in which they work in a constant and permanent deformation mode whatever the force applied, which makes it possible to prestress the assembly constituted by the flanges 8, 9, the washers 12, the cups 13.
  • the flexible metal washers 12 preferably extend in the form of a blade, each of the ends 14, 15 of which can be curved in order to facilitate their attachment within the flange 8, 9, or of the cup 13.
  • cleaning is carried out on the internal face, a plurality of shoulders capable of receiving and holding in position one of the ends of the washer, while the other end of the washer cooperates at the level of preferentially frustoconical notches arranged on the lateral blanks of the bearing ring.
  • the crown 7 is assembled by juxtaposition of two flanges 8, 9 each provided with a plurality of flexible washers 12 and a rolling ring 10, the assembly being connected by a fixing system 16, which passes right through the flanges 8, 9, such as in particular screws.
  • the crown 7 traps between its two flanges 8, 9 the cord 33 of the winch.
  • the winch thus equipped can be disengaged in both directions of use.
  • the superelevated surfaces 6, as a function of the adhesion coefficients of the materials in contact and the value of the friction cone, are calculated so as to allow the engine torque to pass only over a certain range. Beyond, the contacting surfaces slide relative to each other, creating the disengagement. Thus, if the user requests the winch cord excessively when going up or down, the winch system clips these excessively high torque values, detrimental to the mechanical strength of the device and of the rolling shutter assembly as a whole, and stabilizes around an average value.
  • the winch has on its central cylindrical part 2 an engagement zone 17, generally a straight toothing intended to produce the sun gear 18 of an epicyclic train, forming a reducer between the winch part and the integral part of the shaft 19 of the roller shutter deck.
  • this planetary 18 circulates satellites 20, in particular three, arranged at 120 ° and connected to a common shaft 22 which communicates with the shaft 19 of the deck, these satellites 20 also mesh on a fixed crown 21, peripheral placed in the one of the protective casings surrounding the pulley.
  • a brake system 23 Interposed between the shaft of the deck 19 and the shaft 22 linked to the reducer, a brake system 23 of irreversibility.
  • this irreversibility brake 23 consists of an elastically deformable device depending on the type of stresses, generally torsion, applied to one or the other of its ends.
  • a spiral spring 24 is used, the direction of the helix of which is such that, if the strands 25, 26 terminals become integral with the driving lug 28, cooperating at the end of the shaft 22, in such a way that the number of turns of this spring tends to increase, this will tend to decrease the outside diameter of this spring.
  • the latter can therefore rotate freely and will not come into contact with a lining 29 placed at the level of the diameter change zone of the spring and inside the winch frame.
  • a limit switch system 30 in the lower position of the deck.
  • an epicyclic train is developed whose gears forming the satellites and the planetary have a number of prime teeth between them. If we consider a tooth on each gear having this property, the kinematics of these gears determines a single point of crossing for the two teeth considered, this crossing repeating itself according to a period of n turns (n integer). It therefore suffices to determine by a suitable choice of number of teeth of the various gears belonging to the planetary gear, a reduction coefficient between the shaft 22 linked to the winch and the shaft 19 secured to the roller shutter deck, this coefficient also determining the number of turns of the receiving shaft required to move the stroke of said deck.
