- 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 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.

- 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.

Abstract
Description
La présente invention concerne une boîte à ressort de dispositif antichute de rideau roulant à déplacement vertical.The present invention relates to a spring box of a vertical rolling curtain fall arrest device.
Le secteur technique de l'invention est celui de la réalisation d'un dispositif de sécurité et de manoeuvre d'une fermeture de ce type contrôlant l'accès d'un garage, d'un magasin, d'un entrepôt, d'une baie, etc...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 ...
Le but principal de l'invention est de respecter les critères auxquels doivent satisfaire de tels dispositifs de sécurité, notamment dans le cadre des normes, en particulier françaises et européennes.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.
Les normes de référence, et plus particulièrement les normes NFP 25362, NF EN 12453, NF EN 12604 et NF EN 13241-1 spécifient "que les fermetures à effacement vertical doivent comporter un dispositif de retenue, non sollicité en fonctionnement normal, empêchant la chute du tablier en cas de défaillance d'un des éléments du système porteur, sous réserve d'un parcours limité à 0,30 mètre ou 300 mm".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 ".
La défaillance envisagée est par exemple la rupture ou le délestage d'un câble, d'une chaîne, d'une sangle etc... de suspension du rideau, ou encore la rupture d'un ressort de compensation ou de tout autre élément du mécanisme d'enroulement et/ou de suspension du rideau.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.
Ces problèmes sont connus de longue date, et les solutions mécaniques proposées sont très nombreuses et variées.These problems are known for a long time, and the mechanical solutions proposed are very numerous and varied.
Un grand nombre de dispositifs de sécurité reposent sur le principe du décalage angulaire existant entre un arbre menant et un arbre mené reliés par un ressort de rappel. Ce décalage tend à s'annuler en cas de diminution de la charge ou de la force motrice, ou au contraire à s'accroître en cas de surcharge. Une valeur non nominale de ce décalage angulaire déclenche l'arrêt du système, son blocage ou une alarme, que ce soit par des moyens exclusivement mécaniques, ou bien électriques ou électroniques.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.
Le brevet américain
Un autre dispositif de ce genre est décrit dans la demande de brevet
Pour satisfaire plus précisément aux spécifications des normes rappelées ci-dessus, différents systèmes de sécurité ont été développés récemment par différents fabricants, tout en s'appuyant sur des principes mécaniques bien connus dans le domaine technique de référence.To meet more precisely the specifications of the standards mentioned above, various security systems have been developed recently by different manufacturers, while relying on mechanical principles well known in the technical field of reference.
La demande de brevet
De façon également connue en soi, le dispositif de sécurité pour arrêter la chute du tablier en cas de rupture du ressort est tel qu'il permet de coupler la bobine à l'axe fixe après un déplacement angulaire de cette bobine par rapport au dispositif de verrouillage, ce déplacement étant contrôlé par un élément de rappel monté entre la bobine et ce dispositif de verrouillage. Dans ce but, un flasque d'enroulement solidaire de la partie supérieure du tablier est couplé à la bobine grâce à un doigt solidaire de la bobine, et traversant le flasque, pour venir déplacer un élément mobile entre une position d'attente, en fonctionnement normal, et une position de blocage avec une roue crantée solidaire de l'axe fixe, le doigt restant toujours engagé dans le dispositif mobile, en cas de défaillance du ressort.In a manner also known per se, 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. For this purpose, 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.
Une variante plus originale du même dispositif a fait l'objet, par le même déposant, de la demande de brevet
Si ces deux derniers dispositifs de sécurité, basés sur le principe de la détection du déplacement angulaire d'un élément intermédiaire, répondent effectivement aux exigences telles que celles indiquées dans la norme ci-dessus, ils ont comme inconvénient principal, une fois qu'ils ont bloqué la chute du tablier de fermeture, d'empêcher, si ce n'est de pouvoir remonter celui-ci, tout au moins de le descendre complètement pour fermer l'ouverture concernée. Quand la défaillance du système de fermeture a eu lieu en cours de manoeuvre, le tablier est en partie ouvert ou fermé ; pour terminer la manoeuvre, il faut alors démonter le système d'enroulement. Cette opération nécessite l'intervention de techniciens spécialisés qui ne sont pas forcément disponibles au moment de l'incident. Le responsable ou l'usager du local ne peut pas alors fermer l'accès à son local et empêcher toute intrusion non autorisée, ce qui peut être gênant quand il s'agit d'un commerce. De plus, les techniciens doivent intervenir alors qu'une grande partie du tablier tire sur le système d'enroulement et qu'une autre partie est encore enroulée, tandis qu'il n'y a plus de système de compensation et que le système de blocage de sécurité est inaccessible. En effet, dans les deux dispositifs ci-dessus, l'anti-chute est situé à l'intérieur du tablier enroulé ; pour accéder au système de sécurité afin de le débloquer, il faut démonter l'ensemble du système. C'est un travail long et très complexe, qui nécessite de grandes précautions, car des éléments du système, n'étant plus soutenus, risquent d'échapper aux techniciens.If these last two safety devices, based on the principle of the detection of the angular displacement of an intermediate element, actually meet the requirements such as those indicated in the above standard, they have the main disadvantage, once they have blocked the fall of the closing apron, to prevent, if not to be able to go up this one, at least to lower it completely to close the opening concerned. When the failure of the closing system has occurred during operation, the deck is partly open or closed; to complete the maneuver, it is then necessary to disassemble the winding system. This operation requires the intervention of specialized technicians who are not necessarily available at the time of the incident. The manager or the user of the local can not then close access to its premises and prevent unauthorized intrusion, which can be embarrassing when it comes to a business. In addition, the technicians must intervene while a large part of the deck pulls on the winding system and another part is still wound, while there is no more compensation system and the security blocking system is inaccessible. Indeed, in the two devices above, the anti-fall is located inside the rolled apron; To access the security system in order to unlock it, you have to dismantle the entire system. It is a long and very complex work, which requires great caution, because elements of the system, being no longer supported, may escape the technicians.
La demande de brevet
Le blocage de sécurité étant enclenché, et le tablier ou panneau étant arrêté en position à moitié fermé ou ouvert, il est possible:
- d'une part de relever complètement celui-ci, sans avoir à intervenir sur le système d'enroulement proprement dit, et donc d'accéder et d'utiliser son local en attendant les techniciens de dépannage, et
- d'autre part de rabaisser manuellement le tablier pour mettre son local en sécurité si les techniciens ne peuvent intervenir dans un délai raisonnable afin d'éviter à l'usager de devoir exercer une surveillance en les attendant.
- on the one hand to completely recover it, without having to intervene on the winding system itself, and therefore to access and use its premises while waiting for the repair technicians, and
- on the other hand to manually lower the deck to secure his premises if technicians can not intervene within a reasonable time to prevent the user from having to monitor while waiting for them.
Ce dispositif antichute de fermeture à déplacement vertical comporte d'une manière connue, tant dans les dispositifs de fermeture à panneau vertical que dans les systèmes d'entraînement de type « treuil », un arbre fixe, au moins un flasque tournant par rapport à cet arbre et dont la rotation assure le déplacement vertical de la fermeture, et un moyen de compensation du poids de la fermeture par action sur ce flasque.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.
Dans la réalisation décrite, ce moyen de compensation est constitué par un ressort de type « spiral » dont l'extrémité intérieure est fixée sur l'axe fixe et l'extrémité extérieure est fixée à une cloche, couvrant cette extrémité extérieure, et dont une paroi latérale est constituée par le flasque.In the embodiment described, 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.
Le dispositif anti-chute comprend aussi une roue crantée solidaire de l'arbre et un verrou basculant entraîné en rotation par le flasque. Le verrou est apte à coopérer avec au moins un cran de la roue crantée et à bloquer la rotation du flasque pour éviter la descente en chute libre du panneau. De manière remarquable, le verrou basculant comporte de plus un doigt dont au moins un bord latéral de l'extrémité est biseauté suivant un plan sécant avec le cylindre enveloppe de la roue crantée, lequel doigt est monté mobile latéralement par rapport à celle-ci suivant une course lui permettant au moins d'échapper au cran.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. Remarkably, 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.
Ainsi, bien que le tablier de fermeture soit bloqué dans sa descente par le verrou basculant, il est possible de le remonter puisque, dans ce sens, le verrou s'effacera cran après cran et, dès que l'on relâchera le poids du tablier, celui-ci ne pourra pas descendre au-delà du cran dans lequel se bloquera immédiatement le doigt du verrou, son biseau ne permettant son effacement que dans le sens de la remontée.Thus, although the closing apron is blocked in its descent by the rocking latch, it is possible to go up since, in this sense, the lock will fade notch after cran and, as soon as we release the weight of the apron , it will not be able to go down beyond the notch in which will immediately block the finger of the lock, its bevel not allowing its deletion only in the direction of the ascent.
De plus, la roue crantée de ce dispositif comprend au moins deux couronnes. La première comporte les crans de blocage en rotation de la fermeture. La deuxième, placée latéralement par rapport à la première dans le sens du déplacement latéral du doigt, comporte au moins une came dont la face contre laquelle s'appuie le bord latéral en biseau de l'extrémité du doigt est apte à faire échapper celui-ci complètement de la roue crantée dans le sens de la remontée de la fermeture. L'autre face est apte à prendre en appui l'extrémité de ce doigt. Elle est profilée suivant une pente ramenant cette extrémité en face d'un cran de blocage dans le sens de la descente de la fermeture: la distance entre deux positions de cames successives est au moins égale à celle séparant deux crans.In addition, 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.
Ainsi, grâce aux cames de cette deuxième couronne et au biseau du doigt du verrou de blocage, il est possible d'une part de remonter complètement jusqu'en partie haute, comme évoqué précédemment, l'ensemble du tablier de fermeture par effacement du doigt du verrou grâce à son bord latéral biseauté, et d'autre part de redescendre le tablier pas à pas d'une distance correspondant au plus à la distance entre deux cames, le doigt du verrou se relogeant à chaque fois dans un cran de la roue crantée. Il suffit que la distance entre deux positions de cames successives soit inférieure à 300 mm pour respecter la norme indiquée précédemment.Thus, thanks to the cams of this second ring and the bevel of the locking bolt finger, it is possible on the one hand to completely go up to the upper part, as mentioned above, the entire closing plate by erasing the finger the lock with its beveled side edge, and secondly to lower the deck step by step to a distance corresponding to the distance between two cams, the lock finger relocating each time in a notch of the wheel notched. It is sufficient that the distance between two successive cam positions is less than 300 mm to meet the standard indicated above.
Ce dispositif antichute de fermeture à déplacement vertical répond au problème posé et apporte de plus des solutions techniques particulières, qui permettent par exemple:
- de disposer l'ensemble du dispositif de sécurité à l'extérieur du système d'enroulement et de compensation du tablier de fermeture, ce qui permet une intervention plus facile,
- de remonter ou de descendre complètement le tablier de fermeture et de le sécuriser dans cette position en supprimant alors tout effort de rotation sur le système d'enroulement, ce qui simplifie l'intervention des techniciens de dépannage,
- dans le cas d'un dispositif à compensation par ressort de type « spiral », d'éviter que celui-ci, quand il se casse, vienne bloquer le système de sécurité, ce qui peut se produire quand celui-ci est directement lié au ressort de compensation ou à la boite qui enferme celui-ci. En effet, en cas de rupture, le ressort à lame se détend brusquement et s'ouvre au maximum en se plaquant contre la paroi extérieure de la boîte qui le renferme, en risquant d'empêcher tout mouvement de rotation relatif de celle-ci par rapport à tout autre organe, tel que justement de sécurité.
- to arrange the entire safety device outside the winding and compensation system of the closing apron, which allows easier intervention,
- to raise or lower the closing apron completely and to secure it in this position while eliminating any rotational force on the winding system, which simplifies the intervention of the repair technicians,
- in the case of a "spiral" type spring-compensated device, to prevent the latter, when it breaks, from blocking the security system, which may occur when it is directly linked to compensation spring or the box that encloses it. In fact, in the event of breakage, the leaf spring suddenly relaxes and opens as far as possible against the outer wall of the box which encloses it, risking preventing any relative rotational movement of the latter by to any other body, such as security.
Ce dernier risque semble être l'inconvénient de certains dispositifs antichute très simplifiés à ressort spiral, où est seulement mis en oeuvre le déplacement radial ou tangentiel de l'extrémité libre du ressort au moment de la rupture pour contrôler directement une pièce mécanique assurant le blocage.This last risk seems to be the disadvantage of some very simplified fall arrest devices with spiral spring, where is only implemented the radial or tangential displacement of the free end of the spring at the time of rupture to directly control a mechanical part ensuring the blocking .
Des exemples de ces systèmes antichute simplifiés sont décrits notamment dans la demande de brevet
Selon une démarche inverse de celle tendant à une simplification extrême des mécanismes au détriment de la fiabilité, la société demanderesse a déposé le
La présente invention vise à poursuivre la démarche d'amélioration de la boîte à ressort fabriquée par la demanderesse en simplifiant les éléments mécaniques dont ne dépend pas la fiabilité, et en rendant modulaires, et éventuellement remplaçables, les éléments de sécurité.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.
Pour ce faire, la plus grande partie du modèle précédent de boîte à ressort est conservée.To do this, most of the previous model of spring box is retained.
C'est-à -dire que l'invention a pour objet une boîte à ressort de dispositif antichute de rideau roulant à déplacement vertical, cette boîte étant du type de celles de la forme générale d'un cylindre présentant au moins une ouverture latérale et comportant:
- une bobine formée de l'assemblage de deux flasques et dont la rotation autour d'un arbre fixe assure le déplacement vertical du rideau,
- un ressort spiral de compensation du poids du rideau par action sur les flasques, l'extrémité intérieure du ressort de compensation étant destinée à être fixée à l'arbre fixe,
- une roue crantée destinée à être fixée sur cet arbre,
- un verrou basculant apte à coopérer avec au moins un cran de la roue crantée et à bloquer la rotation de la bobine pour éviter la descente du rideau en cas de rupture du ressort de compensation.
- a coil formed of the assembly of two flanges and whose rotation around a fixed shaft ensures the vertical movement of the curtain,
- a spiral spring for compensating the weight of the curtain by acting on the flanges, the inner end of the compensation spring being intended to be fixed to the fixed shaft,
- a notched wheel intended to be fixed on this shaft,
- a tilting latch adapted to cooperate with at least one notch of the toothed wheel and to block the rotation of the coil to prevent the curtain from falling down in the event of rupture of the compensation spring.
Le verrou basculant de ce modèle comprend un doigt articulé par sa base sur l'un des flasques selon une direction axiale et une direction radiale par rapport à l'arbre fixe. Le verrou comprend aussi un ressort de rappel agissant sur le doigt du verrou, de telle sorte que ce doigt, dont au moins un bord latéral de l'extrémité est biseauté suivant un plan sécant avec le cylindre enveloppe de la roue crantée, est susceptible d'échapper au cran au moins en suivant une course selon cette direction axiale.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.
Le verrou à deux degrés de liberté de rotation de l'ancien modèle présente de nombreux avantages: il est aussi conservé.The lock with two degrees of freedom of rotation of the old model has many advantages: it is also preserved.
En revanche, les flasques intermédiaires contre-rotatifs aux flasques de la bobine sont supprimés dans le nouveau modèle, et l'extrémité extérieure du ressort de compensation n'y est plus fixée.On the other hand, the counter-rotating intermediate flanges on the flanges of the spool are removed in the new model, and the outer end of the compensation spring is no longer fixed thereto.
Au contraire, la boîte à ressort de dispositif antichute de rideau roulant à déplacement vertical selon l'invention est remarquable en ce que l'extrémité extérieure du ressort de compensation est rendue solidaire par des moyens de fixation d'une barrette montée mobile en translation dans deux boutonnières parallèles agencées chacune au voisinage de la périphérie de chacun des flasques de la bobine.On the other hand, 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.
Une extrémité de cette barrette coopère avec l'extrémité du doigt du verrou et maintient ce doigt à distance du cran de la roue crantée dans l'état normal du ressort de compensation. L'extrémité de la barrette est dissociée de l'extrémité du doigt du verrou après la rupture du ressort de compensation, libérant de la sorte l'extrémité de ce doigt. Celui-ci est alors entraîné suivant une direction radiale par le ressort de rappel vers le cran de la roue crantée.One end of 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.
De préférence, les moyens de fixation du ressort de compensation sur la barrette comprennent une agrafe.Preferably, the fixing means of the compensation spring on the bar comprise a clip.
Cette barrette est avantageusement constituée d'une tige cylindrique dont les deux extrémités sont munies de circlips coopérant avec les bords des boutonnières agencées dans les flasques.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.
Dans une variante de réalisation de l'invention, l'extrémité de la barrette coopérant avec le doigt du verrou est constituée d'un étrier mobile.In an alternative embodiment of the invention, the end of the bar cooperating with the finger of the lock is constituted by a movable stirrup.
On tire aussi bénéfice du fait que l'extrémité de la barrette coopérant avec le doigt est rappelée en direction opposée à ce doigt par un élément de rappel.It also benefits from the fact that the end of the bar cooperating with the finger is biased in the opposite direction to this finger by a return member.
Dans un mode de réalisation de l'invention, la base du doigt du verrou est articulée sur un téton axial solidaire de l'un des flasques de la bobine.In one embodiment of the invention, the base of the latch finger is articulated on an axial pin integral with one of the flanges of the coil.
Dans un autre mode de réalisation, la base du doigt est articulée sur une tringle cylindrique agencée axialement dans deux alésages de ces flasques.In another embodiment, the base of the finger is articulated on a cylindrical rod arranged axially in two bores of these flanges.
Fort avantageusement, dans un mode de réalisation préféré de l'invention, le verrou est un ensemble mécanique comprenant:
- un flan présentant une patte de fixation et une partie en forme de couronne destinée à être engagée sur l'axe fixe,
- une tringle cylindrique destinée à traverser les flasques de la bobine parallèlement à l'axe fixe, et dont une extrémité est solidaire de ce flan,
- le ressort de rappel dont une extrémité est fixée à la patte du flan, et dont l'autre extrémité porte sur la base du doigt,
- le doigt dont la base est articulée autour de la tringle cylindrique.
- a blank having a fixing lug and a crown-shaped portion intended to be engaged on the fixed axis,
- a cylindrical rod intended to pass through the flanges of the coil parallel to the fixed axis, and one end of which is integral with this blank,
- the return spring whose one end is fixed to the flap of the blank, and the other end of which bears on the base of the finger,
- the finger whose base is articulated around the cylindrical rod.
Selon ce mode de réalisation préféré, avant montage, le verrou comprend de plus un élément de maintien destiné à être supprimé après montage, de préférence un anneau en plastique maintenant comprimé le ressort de rappel.According to this preferred embodiment, before assembly, the lock further comprises a holding member to be removed after mounting, preferably a plastic ring now compressed the return spring.
Fort avantageusement, la base du doigt présente une section droite en forme de U, au moins une lumière oblongue d'une largeur sensiblement égale mais supérieure au diamètre de la tringle ou du téton étant agencée dans au moins une aile dudit U de manière à coopérer avec cette tringle ou ce téton.Advantageously, 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.
L'invention concerne aussi un mécanisme de verrouillage particulièrement adapté à la boîte à ressort décrite précédemment.The invention also relates to a locking mechanism particularly adapted to the spring box described above.
Ce mécanisme, pré-assemblé séparément par un technicien qualifié, est remarquable en ce qu'il comprend:
- un flan présentant une partie en forme de couronne destinée à être engagée axialement sur l'arbre fixe, et une patte de fixation s'étendant perpendiculairement au plan de cette couronne,
- une tringle cylindrique solidaire du flan par une extrémité et s'étendant perpendiculairement au plan de la couronne, cette tringle étant destinée à traverser les flasques de la bobine parallèlement à l'arbre fixe,
- le doigt articulé par sa base autour de la tringle selon une direction perpendiculaire et une direction parallèle au plan de la couronne, dont au moins un bord latéral de l'extrémité est biseauté suivant un plan sécant avec le cylindre enveloppe de cette couronne,
- le ressort de rappel dont une extrémité est fixée à la patte du flan, et dont l'autre extrémité porte sur la base du doigt.
- a blank having a ring-shaped portion intended to be engaged axially on the fixed shaft, and a fastening tab extending perpendicular to the plane of this ring,
- a cylindrical rod secured to the blank at one end and extending perpendicularly to the plane of the ring, this rod being intended to pass through the flanges of the coil parallel to the fixed shaft,
- the finger articulated by its base around the bead wire in a perpendicular direction and a direction parallel to the plane of the crown, at least one side edge of the end of which is beveled along a plane intersecting with the cylinder which surrounds the crown,
- the return spring whose one end is fixed to the flap of the blank, and whose other end is on the base of the finger.
Avant montage pour constituer la boîte à ressort selon l'invention, ce mécanisme de verrouillage comprend de plus avantageusement un élément de maintien, destiné à être supprimé après montage, de préférence un anneau en plastique agencé autour d'au moins une partie de la patte et d'au moins une partie de l'extrémité du doigt, maintenant comprimé le ressort de rappel.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.
De préférence, la base du doigt présente une section droite en forme de U, au moins une lumière oblongue d'une largeur sensiblement égale mais supérieure au diamètre de la tringle d'articulation étant agencée dans au moins une aile du U de manière à coopérer avec cette tringle.Preferably, 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.
Ces quelques spécifications essentielles rendent évidents pour l'homme de métier les avantages supplémentaires apportés par cette boîte à ressort par rapport au modèle précédent de la demanderesse.These few essential specifications make it obvious to the skilled person the additional benefits of this spring box over the previous model of the Applicant.
Les spécifications détaillées de l'invention sont données dans la description qui suit en liaison avec les dessins ci-annexés. Il est à noter que ces dessins n'ont d'autre but que d'illustrer le texte de la description et qu'ils ne constituent en aucune sorte une limitation de la portée de l'invention.The detailed specifications of the invention are given in the following description in conjunction with the accompanying drawings.

Un ressort de compensation 4, de type « spiral », enroulé sur lui-même, dont l'extrémité intérieure 5 est fixée à l'arbre fixe 2, exerce au niveau de son extrémité extérieure 6 un couple antagoniste à celui exercé par le poids du rideau sur la bobine 1.A compensating
Le dispositif antichute comprend également une roue crantée 7 solidaire de l'arbre 2, et un verrou basculant 8 entraîné en rotation par les flasques 3. Ce verrou 8 est apte à coopérer avec au moins un cran 9 de la roue crantée 7 et à bloquer la rotation des flasques 3 pour éviter la descente du rideau.The fall arrest device also comprises a notched

La base du doigt 10 présente une section droite en forme de "U" dont les ailes portent l'orifice 13 et la lumière oblongue d'articulation 15, l'aile correspondant à la lumière oblongue 15 étant courbée pour faciliter son pivotement.The base of the
En effet, le doigt 10 est monté basculant autour de la tringle 12 entre:
- une position d'attente représentée sur la
Figure 1 (ou sur laFigure 5a ), par appui de son extrémité contre l'extrémité d'une barrette 16 (ici une tige cylindrique) solidaire de l'extrémité extérieure 6 du ressort decompensation 4,laquelle tige 16 est en butée dans deux boutonnières 17 rectilignes agencées au voisinage de la périphérie des flasques 3; - et une position de blocage, telle que représentée sur la
Figure 5c , par appui de son extrémité dans un des crans 9 de la roue crantée 7, le basculement du doigt 10 étant assuré par un ressort de rappel 18 quand l'extrémité de la tige 16 s'est effacée.
- a waiting position represented on the
Figure 1 (or on theFigure 5a ), by pressing its end against the end of a bar 16 (here a cylindrical rod) integral with theouter end 6 of thecompensation spring 4, whichrod 16 abuts in tworectilinear buttonholes 17 arranged in the vicinity of the periphery of theflanges 3; - and a locking position, as shown on the
Figure 5c , by pressing its end into one of thenotches 9 of thetoothed wheel 7, the tilting of thefinger 10 being ensured by areturn spring 18 when the end of therod 16 has cleared.

Quand le ressort de compensation 4, dont l'extrémité extérieure 6 recourbée est fixée par une agrafe 19 sur la tige 16, assure son rôle d'équilibre du poids du rideau, le verrou 8 est toujours empêché de basculer grâce à la butée formée par l'extrémité de la tige 16 rappelée en direction de la tringle 12, et de l'arbre fixe 2, par la force exercée par le ressort de compensation 4.When the
Quand le ressort de compensation 4 se rompt, le plus souvent alors qu'il est tendu, c'est-à -dire enroulé, il a tendance à se dérouler, c'est-à -dire que son extrémité extérieure 6 a tendance à s'éloigner de l'arbre fixe 2.When the
La direction générale des boutonnières 17 des flasques étant celles de cordes passant entre l'axe support de rotation du doigt 10, c'est-à -dire la tringle 12, et l'axe de rotation des flasques 3, c'est-à -dire l'arbre 2, toute expansion radiale du ressort de compensation 4, conduisant à un déplacement radial de son extrémité extérieure 6, se traduit par un éloignement de l'extrémité de la tige 16 de l'extrémité du doigt 10.The general direction of the

En fonctionnement normal, la boîte à ressort 1 est donc mobile en rotation autour de l'arbre support fixe 2, grâce à des paliers, et est maintenue en position axiale sur cet arbre 2 grâce à une platine de guidage comprenant la roue crantée 7 autour de laquelle elle peut tourner librement, comme le montrent bien la
Le basculement du verrou 8 autour de son axe de support 12 est limité par tout moyen, tel qu'une butée portée par la platine de guidage ou le flasque 3 en regard, ou un épaulement circulaire formant une troisième couronne 21 à cames 22 disposée latéralement afin que l'extrémité du doigt 10, quand celui-ci est entièrement dégagé de la roue crantée 7 dans le sens de la montée du tablier de fermeture, revienne ensuite, quand on redescend le tablier de fermeture, prendre appui sur une face d'une came 22. Les cames 22 ayant la même hauteur que les dents de la roue crantée 7, le doigt 10 du verrou 8 est ramené ainsi, dans le sens de la descente du tablier de fermeture, vers un cran 9 de la roue crantée 7 où il se bloque en immobilisant le rideau, après avoir permis cependant de dérouler le tablier de la fermeture d'au moins un cran supplémentaire par rapport à la position de blocage précédente.The tilting of the

Cette tige 16 est une pièce intermédiaire qui joue le même rôle que les flasques internes du modèle de boîte à ressort précédent. L'extrémité extérieure 6 du ressort de compensation 4 est rendue solidaire de cette tige 16 par les pattes d'une agrafe 19, de la même manière que l'extrémité extérieure recourbée du ressort de compensation était fixée sur la périphérie des flasques internes.This
