Definitions

  • the present invention relates to a spring box of a vertical rolling curtain fall arrest device.
  • 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 shaft and a driven shaft 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 electrical or electronic.
  • the US patent US-2,878,865 for example, published March 24, 1959 , and owned by the company US Steel, implements this principle, and discloses a device for stopping the fall of a roller shutter in the event, 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 still 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, covering this outer end, and one of which side wall 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.
  • the present invention aims to continue the improvement process of the spring box manufactured by the applicant by simplifying the mechanical elements which does not depend on reliability, and making modular, and possibly replaceable, security elements.
  • the rocking latch of this model comprises a finger articulated by its base on one of the flanges in an axial direction and a radial direction relative to the fixed shaft.
  • the lock also comprises a return spring acting on the finger of the lock, so that this finger, at least one side edge of the end is beveled along a plane secant with the cylinder wrapped with the toothed wheel, is capable of escape the notch at least following a race in this axial direction.
  • the lock with two degrees of freedom of rotation of the old model has many advantages: it is also preserved.
  • the vertical displacement roller shutter device spring box according to the invention is remarkable in that the outer end of the compensation spring is made integral by means of fixing a bar mounted to move in translation in two parallel buttonholes each arranged adjacent the periphery of each of the flanges of the coil.
  • 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 fixing means of the compensation spring on the bar comprise a clip.
  • This bar advantageously consists of a cylindrical rod whose two ends are provided with circlips cooperating with the edges of the buttonholes arranged in the flanges.
  • the end of the bar cooperating with the finger of the lock is constituted by a movable stirrup.
  • the base of the latch finger is articulated on an axial pin integral with one of the flanges of the coil.
  • the base of the finger is articulated on a cylindrical rod arranged axially in two bores of these flanges.
  • the lock before assembly, further comprises a holding member to be removed after mounting, preferably a plastic ring now compressed the return spring.
  • the base of the finger has a U-shaped cross section, at least one oblong slot of a width substantially equal to but greater than the diameter of the rod or the pin being arranged in at least one wing of said U so as to cooperate with this rod or this nipple.
  • the invention also relates to a locking mechanism particularly adapted to the spring box described above.
  • this locking mechanism Prior to assembly to form the spring box according to the invention, this locking mechanism more advantageously comprises a holding element, intended to be removed after mounting, preferably a plastic ring arranged around at least a portion of the leg and at least a portion of the end of the finger, now compressed the return spring.
  • the base of the finger has a U-shaped cross section, at least one oblong slot of a width substantially equal to but greater than the diameter of the hinge rod being arranged in at least one wing of the U so as to cooperate with this rod.
  • FIGS. 1 and 2 are perspective views of a spring box of a vertical rolling shutter fall arrest device according to the invention, respectively showing the locking mechanism mounted, and before mounting.
  • the Figure 3 shows an axial section of the spring box according to the invention.
  • FIGS. 4a and 4b are respectively detailed sections of the finger joint of the lock and the attachment of the locking mechanism according to the invention, shown by the loupes A and B of the Figure 3 .
  • FIGS. 5a, 5b and 5c are partial perspective views, respectively, of the end of the spring of compensation and the latch finger in normal operation, the end of the compensation spring and the latch finger shortly after the breaking of the compensation spring, and the finger engaged in a notch of the toothed wheel when the coil is blocked.
  • 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 3 assembled at their peripheries by spacers 31, and forming a coil with respect to this shaft 2 and whose rotation ensures the vertical displacement of a curtain (not shown) secured to the box 1.
  • the fall arrest device also comprises a notched wheel 7 integral with the shaft 2, and a rocker lock 8 rotated by the flanges 3.
  • This latch 8 is adapted to cooperate with at least one notch 9 of the toothed wheel 7 and to lock the rotation of the flanges 3 to avoid the descent of the curtain.
  • the tilting bolt 8 comprises a finger 10 whose at least one lateral edge 11 of the end 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 a displacement of the finger 10 is allowed by the specific articulation that the lock 8 comprises around a cylindrical rod 12 passing through the flanges 3, which articulation, shown in section on the Figure 4a , comprises an orifice 13 abutting against a shoulder 14 of this rod 12 and an oblong slot 15 located on the same side as the beveled side edge 11 of the blocking finger 10, oblong slot which is of a width substantially equal to but greater than the diameter of the rod 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 4, 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 13 and the elongated hinge slot 15, the wing corresponding to the oblong slot 15 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 16 biased towards the rod 12 and the fixed shaft 2, by the force exerted by the compensation spring 4.
  • buttonsholes 17 of the flanges being those of ropes passing between the support axis of rotation of the finger 10, that is to say the bead wire 12, and the axis of rotation of the flanges 3, that is to say say the shaft 2, any radial expansion of the compensation spring 4, leading to a radial displacement of its outer end 6, results in a distance from the end of the rod 16 of the end of the finger 10.
  • the spring box 1 is thus rotatable about the fixed support shaft 2, thanks to bearings, and is held in axial position on the shaft 2 by means of a guide plate comprising the toothed wheel 7 around it from which it can turn freely, as the Figure 3 and more particularly the Figure 4b .
  • the toothed wheel 7 is fixed on said shaft 1 by a through bolt 20.
  • the tilting of the lock 8 around its support axis 12 is limited by any means, such as a stop carried by the guide plate or the flange 3 opposite, or a circular shoulder forming a third ring 21 with cams 22 arranged laterally. so that the tip of the finger 10, when it is completely clear of the toothed wheel 7 in the direction of the rise of the closing apron, then come back, when we come down the closing apron, bear on a face of a cam 22.
  • the cams 22 having the same height that the teeth of the toothed wheel 7, the finger 10 of the lock 8 is brought thus, in the direction of the descent of the closing apron, to a notch 9 of the toothed wheel 7 where it locks immobilizing the curtain, after however, have allowed to unwind the apron of the closure at least one additional notch compared to the previous locking position.
  • FIGS. 1 and 2 show that the outer end 6 of the compensation spring 4 of the spring box according to the invention is fixed on the bar or rod 16 movable in translation in the flanges.
  • This rod 16 is an intermediate piece that plays the same role as the internal flanges of the previous spring box model.
  • the outer end 6 of the compensation spring 4 is made integral with this rod 16 by the tabs of a clip 19, in the same manner that the curved outer end of the compensation spring was fixed on the periphery of the inner flanges.
  • the end of the rod 16 has the same trigger function as the finger of the anterior internal flange.
  • the energy produced by the expansion of the compensation spring 4, when it breaks, is advantageously used to move the end of the rod 16.
  • the inertia of the rod 16 is much lower than that of the internal flanges, the response time of the parachute is improved.
  • the replacement of the internal flanges by a simple rod 16 also provides the advantages of a material saving in manufacture, and a simplification to assembly.
  • the return spring 18 Before assembly of the mechanism 8 on the flanges 3 and on the shaft 2, the return spring 18 is temporarily associated with a plastic ring 27 arranged around the fixing lug 26 of the return spring 18 and passing through a hole 30 formed in the end of the finger 10, the ring 27 having the effect of maintaining compressed the return spring 18.
  • the embodiment of the latch 8 in the form of a separate mechanism provides many advantages, but is not a technical constraint: the finger 10 is alternatively articulated on an integral pin by construction of one of the flanges 3.
  • the mechanical part on which is fixed the outer end 6 of the compensation spring 4 is not necessarily a cylindrical rod 16 as shown in the various figures. This is usually a bar that slides in two buttonholes 17. These buttonholes are preferably rectilinear, but they are also alternately in a circular arc.
  • the end of this rod, or bar also comprises, in another variant, a movable stirrup on which the finger 10 rests.
  • one or more return elements may, in these variants, connect the rod 16, or the stirrup, to at least one flanges 3.
  • the outer end 6 of the compensation spring 4 is, in the preferred embodiment of the invention, fixed by a clip 19 on the rod 16. Any other means of fixing the outer end 6 of the compensation spring 4 on the rod 16, or the bar, such as bolts and nuts, rivets, glue or solder, would not be beyond the scope of the present invention.
