Definitions

  • a roller shutter generally comprises several compensating springs which are arranged in parallel, each in a housing, and act on the winding axis to balance the weight of the deck.
  • the roller shutter is driven either manually or for example by an electric motor which includes a brake, this brake acting by lack of current.
  • This brake prevents the winding drum from rotating around its axis in the absence of electrical power.
  • the capacities of the electric motor of the brake and of the drive structure are calculated to be sufficient even in the event of failure of one or more compensating springs.
  • the compensating springs fulfill their function, the shutter is subjected to forces much lower than those that the structure can support, and there is no risk of failure, in particular no risk of rupture of the transmission, this rupture can be the cause of a sudden fall of the curtain.
  • the invention finally relates to a rolling shutter comprising a safety device as previously described.
  • the shutter of fig. 1 comprises a fixed shaft 1, forming the axis of rotation of a drum 2 on which the apron 3 of the shutter can be wound.
  • the drum 2 is rotated by an electric motor 4 mounted on a flange 5 fixed on the shaft 1.
  • the flange 5 comprises a reduction gear 6 and a set of pinions engaged with a crown 7 secured to the drum 2.
  • the rotation of the motor 4 and of the reduction gear 6 drives the crown 7 and the drum 2 in rotation around the shaft 1.
  • Two compensation devices are shown on either side of the motor 4. They each include a housing 10, 10 ′ secured to the shaft 1 and a crown 11, 11 'secured to the drum 2.
  • a compensation spring 12, 12' is housed in each housing 10, 10 '.
  • the housing 10 is made from two flanges 10 a and 10 b which are assembled around the spring 12 when the latter is put in place.
  • the housing 10 ′ is manufactured identically.
  • Each spring 12, 12 ' is connected on the one hand to the crown 11, 11' and on the other hand to the central part of the housing 10, 10 '.
  • each spring 12, 12 ' is urged to wind in the opposite direction so that it resists movement and stores energy.
  • each spring 12, 12 ′ unwinds so that it assists in the winding movement.
  • the springs 12 and 12 ′ thus compensate for the weight of the deck 3.
  • FIG. 2 and 3 The mechanism of Figures 2 and 3 is completely inserted into a fixed shaft 201 which serves as an axis of rotation for a drum not shown on which is capable of winding the deck of a roller shutter.
  • a fixed sleeve 204 is fixed with a screw 205 to the shaft 201.
  • a movable sleeve 206 free in rotation receives the free end of a compensating spiral spring 207 by means of a spacer 208 fixed by a screw 209.
  • the other end of the spiral spring 207 is made integral with the winding drum by any appropriate means.
  • an eccentric 230 provided for actuating a switch 231 such as for example a mini-breaker, this mini-breaker being used for controlling the drive device 2.
  • the mini-breaker 231 can be mounted in series with the power supply of the drum drive motor around the shaft 201.
  • the angular movement of the hexagonal profile 220 rotates the eccentric enough for it to trigger the mini-switch 231 by a pressure on its actuator 231a.
  • the angular displacement of a movable sleeve 206 is detected by the mini-switch 231 thanks to the profile 220 which plays the role of actuator, and the information can be transmitted by triggering an alarm or by cutting off the power supply to the drive motor.
