Definitions

  • the present invention relates to an anti-fall device of a flexible structure closing apron capable of being wound around a substantially cylindrical support system and mounted to rotate around a fixed shaft, generally above an opening to condemn.
  • the invention finds a particularly advantageous, but not exclusive, application in the field of vertical erasure closures equipping the accesses of industrial and commercial buildings.
  • curtain or “apron” generally refer to any means capable of closing an opening.
  • the winding of the deck is traditionally performed around at least one spool mounted to rotate on said fixed shaft.
  • This elastic return means is responsible for at least partially counterbalancing the weight of the deck by restoring during the opening phase, the energy stored as torque during the closing phase.
  • roller curtains around a fixed shaft are subject to a number of regulatory and prescriptive requirements.
  • the French standard NF P 25-362 replaced by the European standard EN 12604: 2000, having the status of a French standard, taking effect on January 20, 2001, concerns the safety of users in case of failure of the closing.
  • the outer end of the compensation spring is integral with the locking element which is mounted movably in displacement on the corresponding coil, the locking element being able to move in the direction of a static member integral with the fixed shaft. to cooperate by locking with a stop portion of said static member, said locking member being held away from the static member by the restoring force exerted by the compensation spring.
  • the compensation spring is the only part controlling the immobilization or displacement of the locking element relative to the coil. In other words, it alone ensures the immobilisation of the blocking element in the passive position, it also controls only the displacement in the direction of the static body, and finally it guarantees only the maintenance in active position, the passive and active positions being those in which said blocking element and said static body are respectively at a distance and in contact with each other.
  • the axis 7a is capable of moving axially along an axis parallel XX 'to that YY' of the shaft 3, between two positions A, B, the so-called unlocking A in which it is kept at a distance from the notch 8 of the static member 9, by placing the axial thrust member 101 under stress, by the sole restoring force of the compensation spring, at its outer end.
  • the means for unlocking the flap 7b after its blocking consist of a rocking lever 12, 12A resiliently biased by a return spring 13. 13A, disposed near the notch 8 of the static plate 9, outside thereof and pivotable about a fixed axis 14, 14A perpendicular to the plate 9 and parallel to the axis 7a of the shutter 7b.
