Definitions

  • the invention relates to a device for rotating the winding drum of a roller shutter and a roller shutter comprising such a device.
  • DE-A-35 044 489 discloses a device for manually controlling a electrically driven roller shutter in which a frame is resiliently pushed and wearing a brake shoe, a second shoe can be rotated through a blocking unit.
  • the reduction ratio obtained is low and it is necessary to make the control rod make a large number of turns in order to control the rotation of the shutter.
  • the blocking unit is offset relative to the axis of the shutter winding tube, so that the angular position of the control rod is imposed, which is not without causing difficulties when setting up such a component rolling.
  • US-A-4 651 940 discloses a particularly complex device, therefore expensive, in which a support element connected to a central shaft has a bearing surface capable of cooperating with a disc controlled by translation by an electromagnet.
  • the presence of an electromagnet increases significantly the cost price of the system and the risk of failure.
  • the reducer used does not allow easy handling of the roller shutter by its manual control.
  • the invention solves the problems of the prior art thanks to a device for driving in rotation a winding element of a roller shutter relatively simple to manufacture and use Easy.
  • a device for driving in rotation a roller shutter curtain winding element comprising a motor electric, essentially consisting of a stator and a rotor, and a brake, intended to prevent rotation of said winding element by relative to a fixed casing when said motor is not activated, said brake comprising at least one member, integral in rotation with said rotor and intended to cooperate with at least one blocking element carried by a flange, said motor and said brake being mounted inside said fixed casing, characterized in that said device comprises a fixed crown by report to said housing and a sleeve cooperating with said flange and said ring to form a planetary gear, said sleeve being able to be locked in rotation relative to said crown by means a brake spring.
  • the crown, sleeve and flange form a planetary gear which constitutes an effective reducer for the transmission of movement from the sleeve to the flange when it must be driven in rotation for manual control of the roller shutter.
  • the device includes a drum connected to a manual and coaxial control element with the flange, the sleeve and the crown. Thanks to this aspect of the invention, the manual drive movement is effectively transmitted from the manual control element such as, for example, a rod connected to a crank, up to the flange.
  • the manual control element such as, for example, a rod connected to a crank
  • the brake spring is arranged between on the one hand the crown and on the other hand the drum and the sleeve. This construction allows for a large area of scope of the brake spring inside the drive device ce which allows it to effectively block the rotating flange.
  • the envelope of the brake spring is able to expand radially when applied to drum of a torque transmitted by the sleeve.
  • the envelope of the brake spring does not expand radially when transmitting a torque from the sleeve drum.
  • the drum is surrounded on most of its circumference by a collar of the sleeve.
  • This collar serves as the central core of the brake spring.
  • the element winding can be a cylinder or a disc supporting the deck.
  • the element of blocking can consist of one or two skids in the shape of a crown and the member secured to the rotor is a ring, a disc or a plate.
  • the invention finally relates to a rolling shutter comprising a drive device as previously described.
  • the device of FIG. 1 comprises a fixed casing 1, in which is arranged an electric motor 2 supplied with current by electrical conductors 3.
  • the fixed casing here has the shape of a cylindrical tube circular section but any tube, cylindrical or not, which whatever its section, would be compatible with the invention.
  • the tree of output 4 of the electric motor 2 is engaged with a reduction gear 5 whose outlet is fixed in rotation at the center of a disc 6 at the periphery which is mounted a winding cylinder 7 of the deck not shown a roller shutter.
  • the winding cylinder 7 will be driven to roll up or unwind the roller shutter deck.
  • an assembly 10 forming a brake At the end of the shaft 4 opposite the reduction gear 5 is disposed an assembly 10 forming a brake.
  • this assembly comprises, in particular, a metal ring 11 fixed in rotation relative to the shaft 4, but capable of sliding axially on this shaft.
  • a spiral spring 12 mounted around the shaft 4 bearing against the rotor 2 a of the electric motor 2 and against the internal face of the ring 11 tends to move the ring 11 away from the rotor of the electric motor 2.
  • the electric motor 2 When the electric motor 2 is not activated, no current flows in the rotor 2a and the ring 11 is subjected to the sheer force of the spring 12, thereby the distance from the electric motor.
  • the electric motor operates, the current in the rotor 2 has the electric motor armature magnetic forces which tend to draw the collar 11 towards the rotor and moving in the direction thereof.
  • the ring 11 is closed at its end furthest from the rotor 2a of the motor 2, by a surface 13 substantially orthogonal to the axis of the shaft 4. Moreover, a disk 14 is fixedly mounted in rotation and translation relative to the shaft 4 by means of an elastic pin 15. The distance between the disc 14 and the ring 11 therefore varies according to the position of the ring 11 relative to the rotor of the electric motor.
  • Two pins 16 and 16 ' are mounted in holes in the disc 14 and the ring 11; they carry a plate or tray 17 that they can rotate. Thus the disc 14 and the plate 17 are integral with the rotor 2 a .
  • a flange 18 carries one or two pads 19 and 19 ′ in the form of a crown, immobilized in rotation relative to the latter and arranged inside the space between the disc 14 and the ring 11, on either side of the free plate 17.
  • the operation of the brake motor is as follows: When the electric motor 2 is activated, the magnetic forces induced in the rotor 2 a attract the ring 11 towards the rotor, so that the disc 14 and the ring 11 are spaced apart sufficiently so that the contact between the plate 17, the disc 14 and the ring 11 on the one hand, and the pads 19 and 19 'on the other hand is not blocking. On the contrary, when the motor 2 is not activated, the spring 12 pushes the ring 11 in abutment against the pad 19 ', the ring 11 therefore presses the pad 19' against the plate 17 which is pressed itself against the pad 19 in abutment against the disc 14.
  • the device further comprises means for driving the flange 18 rotating inside the fixed casing 1.
  • These means include a rod 20 connected at its outer end to a reference angle, itself connected to a crank 21 capable of being taken in hand by a user.
  • the end of rod 20 closest to the brake motor is provided with external splines allowing it to be fixed in rotation inside a drive drum 22.
  • the drum 22 is provided with a lug 23. Over the greater part of its circumference not corresponding at the angular sector occupied by the lug 23, the drum 22 is surrounded by a flange 24 of a sleeve 25.
  • the sleeve 25 carries two axes of rotation 26 and 26 'of two toothed wheels 27 and 27'.
  • Wheels 27 and 27 ' are the satellites of a planetary gear centered on the flange 18.
  • the teeth of the toothed wheels 27 and 27 ' are engaged with teeth formed on the one hand on a crown 29 fixed inside the casing 1 and on the other hand on the flange 18.
  • the flange 18 is mounted inside ring 29, the contact between the external cylindrical surface of the flange 18 and the internal cylindrical surface of the crown 29 being a sliding contact.
  • an internal cylindrical part of the crown 29 is arranged around the drive drum 22 of the flange 24 and sleeve 25.
  • a brake spring 30 is disposed in the annular space located between the crown 29, on the one hand, and the drum 22 or the sleeve 25 on the other hand.
  • the rod 20 is rotated by means of the crank manipulated by the user.
  • the drum 22 is then rotated and it rotates the sleeve 25 without being prevented by the spring 30 according to what we saw previously.
  • the sleeve 25, the axes 26 and 26 ', the wheels teeth 27 and 27 ' rotate the flange 18 in the direction of rotation of the rod 20.
  • the shaft 4 being integral with the flange 18 thanks to the assembly brake 10, it is rotated and thereby the reduction gear 5, the disc 6 and cylinder 7 are also set in motion.
  • the roller shutter has been shown with a cylinder 7, but it can operate with one or more discs 6 connected directly to the deck of the roller shutter, in particular if it consists of slats or blades.
  • the invention has been presented with a brake motor with skates, but it applies to any type of brake applicable to its technical field, and in particular a dog brake whose element blocking consists of the dog itself.
