The lock consists of an assembly of at least two articulated links (2, 3) with a slider mechanism. The slider mechanism incorporates a bar (17) pivoted to the end of one link, engaging with teeth on the other. The two links (2, 3) are connected respectively to the blind shaft (6) and the first slat (5) of the blind. The first link (2) is made from metal or plastic, is curved in shape and has a slot (11) for projecting tips on the toothed link (3). Once the bar has engaged with the teeth the blind can only be raised by turning the shaft (6).

Description

La présente invention est relative à un dispositif de verrou automatique pour tablier de volet roulant dont l'axe d'enroulement n'est pas arrêté en rotation.The present invention relates to a device for automatic lock for roller shutter apron of which the winding axis is not stopped in rotation.

Elle vise plus précisément un verrou automatique qui assure à la fois le blocage du tablier lorsqu'il se trouve en position basse - lames emboítées les unes dans les autres - et l'impossibilité de le remonter par toute action extérieure (tentative d'effraction), lorsque la rotation du tablier n'est pas effectuée par le système de manoeuvre.More specifically, it targets an automatic lock which ensures both the locking of the apron when it found in low position - blades fitted together the others - and the impossibility of reassembling it by any external action (attempted break-in), when the deck rotation is not performed by the maneuver.

Dans le cas de la manoeuvre à sangle, l'arbre reste libre en rotation, notamment dans le sens de la remontée du tablier, car la sangle enroulée sur la poulie ne stoppe l'axe d'enroulement du tablier que dans le sens de la descente du tablier, à l'aide du système de frein.In the case of the strap operation, the shaft remains free in rotation, in particular in the direction of the ascent of the apron, because the strap wound on the pulley does not stop the winding axis of the deck only in the direction of the lowering the apron, using the brake system.

Dans le cas de la manoeuvre à treuil possédant un système de débrayage en fin de course basse, l'axe d'enroulement du tablier demeure encore libre en rotation dans le sens de remontée du tablier, le système de mécanisme de débrayage évitant simplement l'enroulement à l'envers du tablier. In the case of a winch maneuver with a system clutch at end of travel, winding axis of the deck remains free to rotate in the direction of the apron, the mechanism mechanism declutch simply avoiding winding upside down apron.

Dans le cas des systèmes de manoeuvre à treuil mûs par un moteur électrique équipé éventuellement d'un mécanisme de roue libre qui évite de ne pas développer d'effort dans le sens de la descente du tablier pour des raisons évidentes de sécurité, ce mécanisme laissant libre en rotation l'axe d'enroulement dans le sens de la remontée du tablier.In the case of winch-operated maneuvering systems electric motor possibly fitted with a freewheeling which avoids not developing any effort in the direction of descent of the apron for reasons safety, this mechanism leaving free in rotation of the winding axis in the ascent direction of the apron.

Les dispositifs connus tels que notamment celui visé dans le brevet français n° 2 720 100, réalise un verrouillage automatique du tablier dans les coulisses, mais ces systèmes fonctionnent tous avec des axes d'enroulement bloqués en rotation par la manoeuvre, lorsque les lames du tablier se trouvent en position basse.Known devices such as in particular that referred to in French Patent No. 2,720,100, locks in behind the scenes, but these systems all work with winding shafts blocked in rotation by the operation, when the blades of the deck are in the low position.

La présente invention vise donc à pallier ces inconvénients en proposant un dispositif qui offre un blocage en rotation de l'axe d'enroulement lorsque le tablier se trouve complètement déroulé indépendamment du système de manoeuvre, tout en garantissant un auto-ajustage du verrou en fonction des dimensions choisies pour les caissons de volet roulant.The present invention therefore aims to overcome these disadvantages by proposing a device that offers a rotation axis lock when the apron is completely unrolled independently of the maneuvering system, while guaranteeing self-adjustment of the lock according to the dimensions chosen for roller shutter boxes.

A cet effet, le verrou pour volet roulant, équipé d'un axe d'enroulement du tablier libre en rotation selon l'invention, se caractérise en ce qu'il comporte un ensemble d'au moins deux maillons articulés entre eux par un système de glissière, et dont l'amplitude de la course est réglée par un système d'échappement formé notamment par une barrette articulée à l'une des extrémités de l'un des maillons et coopérant au niveau de l'autre maillon, chacune des extrémités libres des maillons étant respectivement connectée à l'axe d'enroulement du tablier et à la première lame du tablier.For this purpose, the roller shutter lock, equipped with a axis of winding of the free deck in rotation according to the invention is characterized in that it comprises a set of at least two links hinged together by a slide system, and the amplitude of the stroke is regulated by an exhaust system formed in particular by a bar articulated at one end of one links and cooperating at the level of the other link, each of the free ends of the links being respectively connected to the winding axis of the deck and to the first blade of the deck.

D'autres caractéristiques et avantages de la présente invention ressortiront de la description faite ci-après, en référence aux dessins annexés qui en illustrent un exemple de réalisation dépourvu de tout caractère limitatif. Sur les figures :

  • la figure 1 est une vue en coupe, en élévation latérale, illustrant le mécanisme de verrou complètement enroulé sur l'axe d'enroulement du tube ;

  • la figure 3 est une vue en coupe, en élévation latérale, illustrant la cinématique du mécanisme formant verrou lorsque le tablier est en position basse ;
  • la figure 4 est une vue en perspective du mécanisme formant verrou.
Other characteristics and advantages of the present invention will emerge from the description given below, with reference to the appended drawings which illustrate an embodiment thereof devoid of any limiting character. In the figures:
  • Figure 1 is a sectional view, in side elevation, illustrating the latch mechanism fully wound on the winding axis of the tube;
  • Figure 2 is a sectional view, in side elevation, illustrating the kinematics of the latch mechanism during the descent of the deck;
  • Figure 3 is a sectional view, in side elevation, illustrating the kinematics of the latch mechanism when the deck is in the low position;
  • Figure 4 is a perspective view of the latch mechanism.

Selon un mode préféré de réalisation, le dispositif formant verrou selon l'invention comporte principalement une série de maillons 1, 2, 3, 4, reliant l'axe 6 de rotation du tablier du volet roulant à l'une des lames 5 formant ce tablier.According to a preferred embodiment, the device forming a lock according to the invention mainly comprises a series of links 1, 2, 3, 4, connecting axis 6 of rotation of the roller shutter deck to one of the blades 5 forming this apron.

Ainsi, un premier maillon 1 est relié à l'axe 6 du tablier. Ce maillon 1 s'étend sous la forme d'une plaque de section droite curviligne, préférentiellement réalisée dans une matière plastique ou métallique, afin de s'adapter le plus fidèlement possible à la courbure de l'axe 6 tubulaire.Thus, a first link 1 is connected to the axis 6 of the apron. This link 1 extends in the form of a plate curvilinear cross-section, preferably made in a plastic or metallic material, in order to adapt as closely as possible to the curvature of the tubular axis 6.

Selon un deuxième mode de réalisation (non représenté sur les figures), on substitue au premier maillon 1 une patte qui fait saillie par rapport à l'axe 6 du tablier et qui assure, comme le premier maillon 1, la liaison avec un second maillon 2. According to a second embodiment (not shown in the figures), we replace the first link 1 with a tab which projects from axis 6 of the deck and which like the first link 1, ensures the connection with a second link 2.

Le second maillon 2 qui est connecté à l'autre extrémité libre 8 du premier maillon 1 ou de la patte, notamment à l'aide d'une goupille 9 ou d'une tige, s'articule autour de cet axe 9 liant les deux maillons 1, 2.The second link 2 which is connected at the other end free 8 of the first link 1 or of the lug, in particular at using a pin 9 or a rod, revolves around of this axis 9 connecting the two links 1, 2.

Le débattement angulaire du second maillon 2 par rapport au premier maillon 1 est limité en amplitude par une butée 10 pratiquée au niveau de l'axe d'articulation 9 des deux maillons 1, 2.The angular movement of the second link 2 relative to at the first link 1 is limited in amplitude by a stop 10 made at the hinge pin 9 of the two links 1, 2.

Lorsque le second maillon 2 vient en butée contre le premier maillon 1, il réalise une liaison rigide apte à transmettre un couple ou une force.When the second link 2 abuts against the first link 1, it provides a rigid connection suitable for transmit a torque or a force.

Selon une caractéristique avantageuse, le second maillon 2, réalisé en matière plastique ou métallique, se présente sous la forme d'un élément de profil sensiblement curviligne et comporte, d'une part un évidement central 11 et d'autre part, sur ses parois latérales 12, 13, un orifice 14 oblong. Les lumières 14 ainsi réalisées et l'évidement central 11 autorisent l'articulation et le guidage en translation d'un troisième maillon 3. Ce dernier 3 coopère avec le précédent 2 par l'intermédiaire d'un axe 15 faisant saillie et qui chemine au travers des lumières 14.According to an advantageous characteristic, the second link 2, made of plastic or metallic material, is present as a profile element substantially curvilinear and comprises, on the one hand a central recess 11 and on the other hand, on its walls lateral 12, 13, an oblong orifice 14. The lights 14 thus produced and the central recess 11 allow the articulation and the guiding in translation of a third link 3. The latter 3 cooperates with the previous 2 via an axis 15 making protruding and which travels through the lights 14.

Selon une autre caractéristique avantageuse de l'invention, le second maillon 2 présente à son autre extrémité 16 libre (celle qui n'est pas liée au premier maillon), une barrette 17 articulée autour d'un axe 18 solidaire de l'extrémité du deuxième maillon 2. Cette barrette 17 dans son mouvement oscillant, réalise un mécanisme d'échappement par rapport à des parois inclinées 19 formées sur l'une des faces 20 du troisième maillon 3.According to another advantageous characteristic of the invention, the second link 2 presents to its other free end 16 (the one which is not linked to the first link), a bar 17 articulated around an axis 18 secured to the end of the second link 2. This bar 17 in its oscillating movement, achieves a escape mechanism with respect to walls inclined 19 formed on one of the faces 20 of the third link 3.

Le mouvement de débattement angulaire de la barrette 17 par rapport à son axe d'articulation 18, est limité par un système de butée pratiqué à l'extrémité du second maillon 2.The angular movement of movement of the bar 17 relative to its axis of articulation 18, is limited by a stop system practiced at the end of the second link 2.

Selon une autre caractéristique avantageuse de l'invention, le troisième maillon 3, réalisé en matière plastique ou métallique, se présente également sous la forme d'un élément de profil curviligne ; il comporte sur sa face externe 20 une pluralité de zones en relief formant des crans 19 à la manière d'une roue à rochet.According to another advantageous characteristic of the invention, the third link 3, made of plastic or metallic, also occurs under the shape of a curvilinear profile element; it features on its outer face 20 a plurality of raised areas forming notches 19 in the manner of a ratchet wheel.

Les crans 19 ainsi formés emprisonnent la barrette 17 et offrent en fonction du débattement angulaire de celle-ci et de la position du troisième maillon 3 par rapport au second maillon 2, une pluralité de positions de réglage et de blocage.The notches 19 thus formed trap the bar 17 and offer depending on its angular travel and the position of the third link 3 relative to the second link 2, a plurality of adjustment positions and blocking.

Le troisième maillon 3 est rendu solidaire par l'intermédiaire notamment d'une goupille 21 à un quatrième maillon 4 relié quant à lui à la première lame 5 du tablier qui chemine au travers de la tulipe 22 solidaire de la coulisse du châssis du volet roulant.The third link 3 is made integral by in particular through a pin 21 to a fourth link 4 connected to the first blade 5 of the apron which runs through the tulip 22 secured to the slide of the roller shutter frame.

En fonction des dimensions du caisson devant recevoir le tablier du volet roulant, le dispositif de verrou selon l'invention sera modifié, par le retrait du quatrième maillon 4 ou par l'ajout d'un deuxième maillon 4, afin d'allonger le système.Depending on the dimensions of the box to receive the roller shutter curtain, the locking device according to the invention will be modified by the withdrawal of the fourth link 4 or by adding a second link 4, so to lengthen the system.

Selon une autre caractéristique avantageuse de l'invention, la barrette 17 tourne autour de son axe d'articulation 18 sur le deuxième maillon 2 de manière à pouvoir se rabattre sur le troisième maillon 3, lors de l'enroulement du tablier. A cette fin, elle comporte à l'une de ses extrémités, une patte 23 qui permet d'escamoter la barrette 17 lors de l'enroulement.According to another advantageous characteristic of the invention, the bar 17 rotates around its axis articulation 18 on the second link 2 so as to be able to fall back on the third link 3, when winding the deck. To this end, it includes one of its ends, a tab 23 which allows retract the bar 17 during winding.

Selon encore une autre caractéristique avantageuse de l'invention, on dispose au niveau de l'articulation 9 reliant le premier maillon 1 et le second maillon 2 un organe élastique 24 du type ressort, de manière à faire pivoter le second maillon 2 contre ce premier maillon 1 et laisser ainsi libre le coulissement du troisième maillon 3 au sein des coulisses 14 oblongues pratiquées dans le second maillon, ce mouvement se perpétuant jusqu'à ce que la barrette 17 vienne au contact d'un cran 19 pratiqué en surface du troisième maillon 3.According to yet another advantageous characteristic of the invention, there is at the joint 9 connecting the first link 1 and the second link 2 one elastic member 24 of the spring type, so as to make pivot the second link 2 against this first link 1 and thus allow the sliding of the third link 3 within the 14 oblong slides made in the second link, this movement continues until bar 17 comes into contact with a notch 19 practiced on the surface of the third link 3.

Le mode de fonctionnement du dispositif objet de l'invention, formant verrou entre le tablier du volet roulant et l'axe de rotation du tablier est le suivant :
On réalise une liaison rigide entre le tube et la première lame du tablier grâce à l'ensemble des maillons 1, 2, 3, 4, qui viennent en butée positive l'un contre l'autre, afin de former un ensemble rigide en position déroulée du tube.The operating mode of the device which is the subject of the invention, forming a lock between the roller shutter deck and the axis of rotation of the deck is as follows:
A rigid connection is made between the tube and the first blade of the deck thanks to the set of links 1, 2, 3, 4, which come into positive abutment against one another, in order to form a rigid assembly in position unwound from the tube.

Le mouvement de l'ensemble des maillons se décompose de la manière suivante : le premier maillon 1 demeure solidaire du tube d'enroulement, le deuxième maillon s'articule autour de son axe 9 jusqu'au moment où il vient en butée contre le premier maillon 1.The movement of all the links breaks down as follows: the first link 1 remains secured to the winding tube, the second link revolves around its axis 9 until it abuts against the first link 1.

Le quatrième maillon 4, qui peut être éventuellement ôté en fonction de la configuration choisie, est attelé à la première lame 5 du tablier. Ce quatrième maillon 4 s'articule autour d'un axe 21 jusqu'au moment où il vient en butée contre le troisième maillon 3.The fourth link 4, which can optionally be removed depending on the configuration chosen, is coupled to the first blade 5 of the deck. This fourth link 4 revolves around an axis 21 until it comes in abutment against the third link 3.

Le deuxième maillon 2 comporte de chaque côté une lumière oblongue 14, afin de permettre le déplacement de l'axe d'articulation 15 du troisième maillon 3 par rapport au deuxième maillon 2. Ce déplacement a lieu lorsque le tablier est complètement descendu dans les coulisses et jusqu'à ce que le tube ait terminé sa rotation, lors de sa position de blocage final. The second link 2 has a light on each side oblong 14, to allow movement of the axis of articulation 15 of the third link 3 with respect to the second link 2. This displacement takes place when the apron went completely backstage and until the tube has finished rotating, when its final blocking position.

C'est dans cette période que s'effectue l'auto-ajustage en longueur du mécanisme de verrou. La barrette 17 articulée vient s'engager dans l'un des crans 19 prévus en surface 20 du troisième maillon 3, afin d'immobiliser celui-ci 3 par rapport au deuxième maillon 2 et réaliser la liaison rigide recherchée entre le tube d'enroulement du tablier et la première lame du tablier.It is during this period that self-adjustment is carried out in length of the latch mechanism. Bar 17 articulated engages in one of the notches 19 provided on the surface 20 of the third link 3, in order to immobilize this one 3 compared to the second link 2 and realize the desired rigid connection between the winding tube of the apron and the first blade of the apron.

Selon une autre caractéristique avantageuse de l'invention, on prévoit de disposer au bout de l'axe supportant le tube d'enroulement du tablier 6, un organe élastique notamment du type ressort plat hélicoïdal, afin de créer un léger couple qui est nécessaire à la rotation du tube dans le sens de la descente ; ce montage est particulièrement utilisé dans le cas d'une manoeuvre à sangle. Cet organe élastique garantit que la barrette 17 est en prise sur l'un des crans 19 réalisés sur la face 20 du troisième maillon 3.According to another advantageous characteristic of the invention, it is planned to have at the end of the axis supporting the winding tube of the deck 6, a member elastic in particular of the flat helical spring type, so to create a slight torque which is necessary for the rotation of the tube in the direction of descent; this montage is particularly used in the case of a maneuver to strap. This elastic member guarantees that the bar 17 is engaged on one of the notches 19 made on the face 20 of the third link 3.

L'invention telle que décrite ci-dessus offre de multiples avantages : elle concilie tous les paramètres de fonctionnement (la hauteur optimale du tablier, l'arcboutement du verrou), cette manoeuvre pouvant être définie en atelier et affinée sur le chantier, par l'ajout à l'une des extrémités des deux maillons principaux formant verrou, de maillons supplémentaires, afin de s'adapter au gabarit du caisson du volet roulant, quel que soit le type d'organe de manoeuvre et particulièrement ceux qui laissent libres en rotation l'axe d'enroulement du tablier, le réglage final sur le chantier s'effectue automatiquement grâce aux lumières ménagées dans l'un des maillons du verrou ce qui permet l'auto-ajustage en longueur du mécanisme.The invention as described above offers multiple advantages: it reconciles all parameters of operation (the optimal height of the deck, the arching of the lock), this maneuver being able to be defined in the workshop and refined on site, by adding at one end of the two links main lock, additional links, in order to adapt to the size of the roller shutter box, whatever the type of actuator and especially those who allow free rotation the winding axis of the deck, the final adjustment on the site is carried out automatically thanks to the lights formed in one of the links of the lock which allows self-adjusting length of the mechanism.

Il demeure bien entendu que la présente invention n'est pas limitée aux exemples de réalisation décrits et représentés ci-dessus, mais qu'elle en englobe toutes les variantes.Of course, the present invention is not not limited to the embodiments described and shown above, but that it includes all variants.
