Definitions

  • the present invention relates to a spring box roll-arrestor device with vertical movement secured with rolling, and corresponding safety elements.
  • the technical sector of the invention is that of the realization of a safety device and maneuvering a closure of this type controlling the access of a garage, a store, a warehouse, an bay, etc ...
  • the main purpose of the invention is to meet the criteria that must meet such safety devices, especially in the context of standards, particularly French and European.
  • the reference standards and more particularly the standards NFP 25362, NF EN 12453, NF EN 12604 and NF EN 13241-1 specify "that vertical erasure closures must include a restraint, unsolicited in normal operation, preventing the fall of the deck in case of failure of one of the elements of the carrier system, subject to a path limited to 0.30 meter or 300 mm ".
  • the considered failure is for example the breaking or unloading of a cable, a chain, a strap etc ... of suspension of the curtain, or the rupture of a compensation spring or any other element of the mechanism for winding and / or suspending the curtain.
  • a large number of safety devices are based on the principle of the angular offset between a driving element and a driven element connected by a return spring. This shift tends to cancel in the event of a reduction in the load or the driving force, or on the contrary to increase in the case of overload.
  • a non-nominal value of this angular offset triggers the shutdown of the system, its blocking or an alarm, whether by exclusively mechanical means, or by electrical or electronic means.
  • the US patent US 2878865 for example, published March 24, 1959, and which held the company US Steel, implements this principle and discloses a device for stopping the fall of a roller shutter in case, in particular, rupture of the compensation spring.
  • the locking element is a pawl associated with a ratchet wheel.
  • the patent application FR-2.739.656 published April 11, 1997, in the name of G. Tournier describes a device for actuating a roll-up closure having a spring-loaded fall arrest system.
  • the device comprises a fixed axis on which is mounted at least one coil provided with at least one spiral compensation spring.
  • the inner end of the spring is integral with the fixed axis and its outer end is integral with the coil, the latter being itself coupled to the upper end of the apron performing the closure. winding.
  • the safety device for stopping the fall of the apron in case of breakage of the spring is such that it allows coupling the coil to the fixed axis after an angular displacement of this coil relative to the locking device, this movement being controlled by a return element mounted between the coil and this locking device.
  • a winding flange secured to the upper part of the deck is coupled to the coil by a finger secured to the coil, and passing through the flange to move a movable member between a waiting position, in operation normal, and a locking position with a toothed wheel secured to the fixed axis, the finger remaining always engaged in the mobile device in case of failure of the spring.
  • This vertical displacement locking device comprises in a known manner, both in the vertical panel closing devices and in the "winch" type drive systems, a fixed shaft, at least one flange rotating relative to this shaft and whose rotation ensures the vertical movement of the closure, and a means of compensation of the weight of the closure by action on the flange.
  • this compensation means is constituted by a "spiral" type spring whose inner end is fixed on the fixed axis and the outer end is fixed to a bell which covers this outer end and a wall of which lateral is constituted by the flange.
  • the fall arrest device also comprises a toothed wheel secured to the shaft and a rocking lock rotated by the flange.
  • the lock is adapted to cooperate with at least one notch of the toothed wheel and to block the rotation of the flange to prevent the free fall of the panel.
  • the rocker lock further includes a finger, at least one side edge of the end is beveled along a plane secant with the casing cylinder of the toothed wheel, which finger is laterally movable relative thereto a race allowing him at least to escape the guts.
  • the toothed wheel of this device comprises at least two rings.
  • the first comprises locking notches in rotation of the closure.
  • the second placed laterally with respect to the first in the direction of the lateral displacement of the finger, comprises at least one cam whose face against which the beveled lateral edge of the end of the finger rests is able to evade this. this completely from the notched wheel in the direction of the rise of the closure.
  • the other face is able to bear the end of this finger. It is profiled along a slope bringing this end in front of a locking catch in the direction of the descent of the closure: the distance between two positions of successive cams is at least equal to that separating two notches.
  • This bar cooperates with the finger end of the lock and keeps this finger away from the notch of the notched wheel in the normal state of the compensation spring.
  • the end of the bar is disassociated from the end of the lock finger after the breaking of the compensation spring, releasing the end of this finger. This is then driven in a radial direction by the return spring towards the notch of the toothed wheel.
  • the present invention therefore aims to overcome this disadvantage, and to improve the reliability of the latest model fall arrest device manufactured by the applicant company.
  • the vertical displacement roller shutter device spring box according to the invention is remarkable in that the release of the finger is further prevented in the normal state of the compensating spring, during curtain maneuvers, by means safety.
  • these safety means comprise at least one safety catch arranged at the end of the finger and cooperating with the end of the bar.
  • this safety catch consists of a safety tooth arranged at the end of the finger and cooperating with the end of the bar.
  • the safety catch is also advantageously constituted by a safety notch arranged at the end of the finger and cooperating with the end of the bar.
  • this notch and this tooth have a common wall, the notch being arranged after the tooth towards the end of the finger.
  • the first end of said bar is very advantageously constituted by a cylindrical rod.

  • the notch and / or the tooth are made in a safety lever fixed on the finger by snapping and traversed by a hinge axis of the finger on the first flange.
  • the safety hook or the safety lever of this first preferred embodiment is either, and preferably, made of plastic or metal.
  • the safety means of the spring box fall arrest device advantageously comprise at least one piece of link connecting the bar and the coil, this connecting piece having a predetermined mechanical strength greater than the first forces undergone in the normal state of the compensation spring, and lower than the second forces experienced in the case of the breaking of the compensation spring .
  • this connecting piece connects the bar at least to the first flange or to the second flange.
  • the connecting piece is very advantageously constituted by an elongate blade having a transverse constriction.
  • the connecting piece consists of a wire.
  • the connecting piece is connected to an axis of articulation of the latch finger on the first flange.
  • said safety means comprise two copies of the connecting piece arranged respectively at the first end of the bar and at a second end of this bar.
  • the invention also relates to safety elements for composing the spring box described above.
  • a first type of safety element is conspicuously constituted of a plate of the general shape of a hook comprising a triangular part having an edge comprising the tooth or the safety notch, a hollowed out central part intended to allow the insertion on the first or the second flange, and a rounded portion adapted to surround an axis of articulation of the base of the finger of the rocking lock.

  • This blade preferably comprises at one end a first light adapted to surround a portion of the bar and at the other end a second light adapted to surround a pivot axis of the finger of the rocking lock.
  • the safety elements according to the invention are very advantageously, whatever their types, either made of plastic material or metal.
  • the spring box 1 of the fall arrest device for closing vertical displacement in question is mounted on a fixed shaft 2. It comprises two flanges 3a, 3b assembled at their peripheries by spacers 4, forming a rotating spool with respect to this shaft 2 and whose rotation ensures the vertical movement of a curtain (not shown) secured to the box 1.
  • the fall arrest device also comprises a toothed wheel 7, integral with the shaft 2, and a rocker lock 8 rotated by the flanges 3a, 3b.
  • This lock 8 is adapted to cooperate with at least one notch 9 of the toothed wheel 7 and to block the rotation of the flanges 3a, 3b to prevent the curtain from going down.
  • the rocking lock 8 comprises a finger 10, at least one lateral edge 11 of the end of which is bevelled along a plane intersecting with the casing cylinder of the toothed wheel 7, which is of the same axis as the fixed shaft 2.
  • the finger 10 is mounted laterally movable with respect to the toothed wheel 7 in a race allowing it to at least escape the notch 9, the secant plane being inclined of course in the direction of the lateral displacement of the lock 8.
  • Such displacement of the finger 10 is allowed by the specific articulation that the latch 8 comprises around a cylindrical rod 12 passing through the flanges 3a, 3b, which articulation comprises an orifice abutting against a shoulder of this rod 12 and an oblong slot situated on the same side as the beveled side edge 11 of the blocking finger 10, an oblong slot which is of a width substantially equal to but greater than the diameter of the bead wire 12 so as to make possible the lateral displacement of the finger 10.
  • This movement must allow the latch 8 to escape at least the notch 9 in which it would be blocked, for example following the break of the compensation spring 5, by pivoting the latch 8 around the rod 12 in an axial plane.
  • the base of the finger 10 has a U-shaped cross section whose wings carry the orifice and the oblong slot of the joint, the wing corresponding to the oblong slot being bent to facilitate its pivoting.
  • the latch 8 is always prevented from tilting thanks to the stop formed by the end of the rod 13 biased towards the rod 12, and towards the fixed shaft 2, by the force exerted by the compensation spring 5.

  • the spring box 1 In normal operation, the spring box 1 is rotatable about the fixed support shaft 2, thanks to bearings, and it is maintained in axial position on the shaft 2 by means of a guide plate comprising the toothed wheel 7 around which she can turn freely.
  • the toothed wheel 7 is fixed on the shaft 2 by a through bolt.
  • the tilting of the lock 8 around its support axis 12 is limited by any means, such as an abutment carried by the guide plate or the flange 3a opposite, or a circular shoulder forming a third ring 18 cam 19 disposed laterally so that the end of the finger 10, when it is completely clear of the toothed wheel 7 in the upward direction of the closing apron, then return, when the closing apron is lowered, to bear on one side of a cam 19.
  • FIGS. 1 and 4 show that the outer end 6 of the compensation spring 5 of the spring box 1 according to the invention is fixed on the bar or rod 13 movable in translation in the flanges 3a, 3b.
  • This rod 13 is an intermediate piece which plays a role of attachment similar to that of the counter-rotating internal flanges of one of the previous spring box models.
  • the outer end 6 of the compensation spring 5 is secured to said rod 13 by the tabs of a clip 17, in the same manner that the curved outer end of the compensation spring was fixed on the inner flanges. .
  • the end of the rod 13 has for its part the same trigger function as the finger of the anterior internal flange.
  • the energy produced by the expansion of the compensation spring 5 during its break is advantageously used to move the end of the rod 13.
  • the inertia of the rod 13 being much weaker than that of the internal flanges of the previous model, the response time of the parachute is improved.
  • the replacement of the inner flanges by a single rod 13 also provides the advantages of a saving of material in manufacture, and a simplification during assembly.
