Description

L'invention concerne un verrou de liaison entre un tablier et un arbre d'enroulement du volet roulant. Le domaine d'application de l'invention et donc naturellement celui des volets roulants.The invention relates to a connection lock between an apron and a winding shaft of the roller shutter. The field of application of the invention and therefore naturally that of roller shutters.

Les volets roulants sont utilisés au niveau des ouvertures des bâtiments telles que par exemple des portes ou des fenêtres. Ils peuvent être utilisés comme un moyen de protection, c'est-à-dire empêcher une intrusion à l'intérieur du bâtiment en l'absence du propriétaire des lieux ou pour régler la luminosité à l'intérieur d'une pièce en réglant la hauteur du déroulement du volet ou selon modèle, en inclinant les lames du tablier.Roller shutters are used at the openings of buildings such as for example doors or windows. They can be used as a means of protection, ie to prevent intrusion into the building in the absence of the owner of the premises or to adjust the brightness inside a room by adjusting the height of the shutter or depending on the model, tilting the apron blades.

Un volet roulant comporte généralement un coffre disposé en partie supérieure de l'ouverture. Un arbre d'enroulement du volet est disposé dans ce coffre et directement relié à un moteur ou une manivelle permettant de dérouler manuellement le volet. L'invention concerne plus particulièrement la liaison mécanique entre le tablier et l'arbre d'enroulement du volet roulant.A roller shutter generally comprises a chest arranged in the upper part of the opening. A winding shaft of the flap is disposed in this trunk and directly connected to a motor or a crank for manually unwinding the flap. The invention relates more particularly to the mechanical connection between the deck and the winding shaft of the shutter.

Il est connu en référence aux documents EP 1 728 962 et EP-A-1 726 771 qu'un volet roulant peut contenir un dispositif d'attelage entre le tablier du volet roulant et l'arbre d'enroulement. Ce dispositif d'attelage est un verrou de liaison qui est attelé en une première extrémité soit directement à l'arbre d'enroulement, au moyen d'un crochet et de rainures spécifiquement disposées sur l'arbre d'enroulement, soit au moyen de bagues enfilées autour de l'arbre d'enroulement et qui sont reliées au verrou de liaison grâce à une broche de liaison. Ce verrou de liaison comporte, en une deuxième extrémité, un dispositif d'attache avec le tablier, ou plus spécifiquement avec la première lame du tablier. Les deux extrémités sont reliées par des maillons articulés selon un axe parallèle à l'axe longitudinal de l'arbre d'enroulement et qui sont aptes à se bloquer lorsque le volet est totalement déroulé et donc d'assurer une fonction de verrou.It is known with reference to the documents EP 1 728 962 and EP-A-1,726,771 a roller shutter may contain a coupling device between the rolling shutter apron and the winding shaft. This coupling device is a link lock which is coupled at a first end either directly to the winding shaft, by means of a hook and grooves specifically arranged on the winding shaft, or by means of rings threaded around the winding shaft and which are connected to the link lock by means of a connecting pin. This connection lock comprises, at a second end, a fastening device with the apron, or more specifically with the first blade of the deck. The two ends are connected by links articulated along an axis parallel to the longitudinal axis of the winding shaft and which are able to lock when the flap is fully unwound and thus to provide a lock function.

En particulier, EP-A-1 726 771 divulgue un dispositif d'attelage entre le tablier et l'arbre d'enroulement d'un volet roulant, la particularité étant que ce dispositif d'attelage comporte un profil de liaison amovible et réversible. La réversibilité de ce profil de liaison entre le tablier et le verrou de liaison permet d'accrocher deux types de tablier ayant deux épaisseurs de lames différentes. Cela permet en outre de décrocher le tablier du verrou de liaison sans pour autant avoir à enlever le verrou de liaison de l'arbre d'enroulement. Le profil de liaison présente une forme en H dont les extrémités d'une des branches sont repliées en angle droit vers l'autre branche. Ainsi, une fois que le profil de liaison a été retiré du verrou de liaison, par un mouvement de translation, il est impossible de décrocher le profil de liaison du tablier autrement qu'en le faisant glisser le long de la première lame du tablier jusqu'à son extrémité. Cette opération nécessite d'avoir un dégagement latéral au niveau du tablier de la longueur d'au moins celle du profil de liaison amovible. Ceci est particulièrement désavantageux car il n'y a pas toujours assez d'espace à l'extrémité latérale du tablier pour pouvoir dégager le profil de liaison. En particulier on peut imaginer la présence d'un mur, d'une joue support de manoeuvre ou d'une coulisse latérale, qui empêcherait l'extraction du profil de liaison amovible sur le côté et empêcherait ainsi de désolidariser le profil de liaison du tablier. Or, pour des volets de grande largeur, plusieurs verrous de liaison sont répartis sur la longueur de la première lame afin de répartir le poids du volet. Ainsi, pour retirer le profil de liaison du tablier, il convient de détacher les autres verrous de liaison jusqu'à l'extrémité latérale. Ceci est évidemment très contraignant et augmente considérablement le temps de démontage d'un volet roulant.In particular, EP-A-1,726,771 discloses a coupling device between the deck and the winding shaft of a roller shutter, the particularity being that this coupling device comprises a removable and reversible connection profile. The reversibility of this connection profile between the deck and the connection lock makes it possible to hang two types of deck having two different thicknesses of blades. This also makes it possible to unhook the deck of the link lock without having to remove the connection lock of the winding shaft. The connection profile has an H-shape whose ends of one of the branches are bent at right angles to the other branch. Thus, once the link profile has been removed from the link lock, by a translational movement, it is impossible to unhook the deck connection profile other than by sliding it along the first apron blade to its end. This operation requires to have a side clearance at the deck of the length of at least that of the removable connection profile. This is particularly disadvantageous because there is not always enough space at the lateral end of the deck to be able to clear the connection profile. In particular one can imagine the presence of a wall, a cheek support or a lateral slide, which would prevent the extraction of the removable connection profile on the side and thus prevent the disassembly of the connection profile of the apron . However, for flaps of large width, several connection locks are distributed over the length of the first blade to distribute the weight of the flap. Thus, to remove the connection profile of the deck, it is necessary to detach the other connection locks to the lateral end. This is obviously very restrictive and considerably increases the disassembly time of a roller shutter.

C'est à ces inconvénients qu'entend plus particulièrement remédier l'invention en proposant un verrou de liaison plus pratique à installer et à désinstaller.It is these drawbacks that the invention intends to remedy more particularly by proposing a connection lock that is more practical to install and to uninstall.

A cet effet l'invention concerne un verrou de liaison pour volet roulant, permettant la liaison entre le tablier et l'arbre d'enroulement du volet, ce verrou comprenant au moins deux maillons articulés entre eux selon un axe d'articulation parallèle à l'axe géométrique de l'arbre d'enroulement du volet, dont un maillon supérieur attaché avec l'arbre d'enroulement et dont un maillon inférieur et pourvu d'un profil de liaison au tablier. Conformément à l'invention, le profil de liaison et le maillon inférieur définissent entre eux un espace de coincement d'une boucle d'accrochage du tablier, alors que le profil de liaison peut être libéré du tablier en le retirant du maillon inférieur par un mouvement de translation axiale, puis en le dégageant transversalement du tablier.For this purpose the invention relates to a connection lock for roller shutter, allowing the connection between the deck and the winding shaft of the flap, this latch comprising at least two links articulated between them along an axis of articulation parallel to the door. geometric axis of the winding shaft of the flap, including an upper link attached with the winding shaft and including a lower link and provided with a connection profile to the deck. In accordance with the invention, the connecting profile and the lower link define between them a wedging space of a hanging loop of the deck, while the connecting profile can be released from the deck by removing it from the lower link by a axial translational movement, then releasing it transversely of the apron.

Grâce à l'invention, il est désormais possible de détacher le profil de liaison du tablier sans le faire glisser jusqu'à l'extrémité de la première lame du tablier, c'est-à-dire selon une direction perpendiculaire à l'axe longitudinal de l'arbre d'enroulement, en configuration montée du tablier sur l'arbre d'enroulement. En effet, en configuration assemblée du profil de liaison sur le maillon inférieur, la boucle d'accrochage du tablier est enfermée, ou coincée, entre le profil de liaison et le maillon inférieur, alors que, lorsque l'on retire le profil de liaison du maillon inférieur, la boucle n'est plus coincée entre le maillon inférieur et le profil de liaison et il est possible de détacher transversalement le profil de liaison du tablier.. Par ailleurs, le maillon inférieur est avantageusement revêtu d'une matière plastique à très faible coefficient de frottement afin de ne pas agresser la peinture déposée sur les lames lors de l'enroulement du tablier. De plus, afin de marquer le moins possible les lames du tablier par ce verrou de liaison au cours des cycles d'enroulement et de déroulement du volet roulant, le verrou de liaison a été conçu de manière à ce que le maillon supérieur et les maillons intermédiaires ont une épaisseur légèrement inférieure à celle des bagues auxquelles est rattaché le verrou de liaison.Thanks to the invention, it is now possible to detach the connection profile of the deck without sliding it to the end of the first deck blade, that is to say in a direction perpendicular to the axis longitudinal axis of the winding shaft, in mounted configuration of the deck on the winding shaft. Indeed, in the assembled configuration of the link profile on the lower link, the apron latching loop is enclosed, or wedged, between the link profile and the lower link, while, when removing the link profile of the lower link, the loop is no longer wedged between the lower link and the connecting profile and it is possible to detach transversely the connection profile of the deck .. Furthermore, the lower link is advantageously coated with a plastic material to very low coefficient of friction so as not to attack the paint deposited on the blades during the winding of the deck. In addition, to mark as little as possible the deck blades by this connecting lock during the winding and unwinding cycles of the shutter, the connecting lock was designed so that the upper link and the intermediate links have a slightly lower thickness to that of the rings to which the connection lock is attached.

Selon des aspects avantageux mais non obligatoire de l'invention, un verrou de liaison peut incorporer une ou plusieurs des caractéristiques suivantes, prises dans toute combinaison techniquement admissible :

  • Le maillon inférieur est apte à verrouiller l'assemblage du profil de liaison avec la lame supérieure du tablier.
  • Le profil de liaison présente un moyen d'accrochage à la lame supérieure du tablier.
  • Le moyen d'accrochage inclut un crochet qui est porté par le profil de liaison et qui est apte à s'accrocher sur une boucle portée par la lame supérieure du tablier.
  • L'espace entre le maillon inférieur et le profil de liaison, en configuration montée du profil de liaison sur le maillon inférieur, est inférieur au diamètre d'ouverture de la boucle de manière à ce que la boucle ne puisse pas se décrocher du profil de liaison.
  • Le profil de liaison et le maillon inférieur présentent des moyens de fixation élastique permettant de fixer le profil de liaison au maillon inférieur.
  • Les moyens de fixation élastique incluent une languette solidaire du maillon inférieur et une ouverture située sur le profil de liaison alors que la languette est apte à rentrer dans l'ouverture, immobilisant ainsi le profil de liaison par rapport au maillon inférieur.
  • Le maillon inférieur du verrou comporte sur sa surface externe c'est-à-dire directement en contact avec le tablier lors de l'enroulement du tablier autour de l'arbre d'enroulement, une matière plastique ayant un coefficient de frottement inférieur à 0.12 quand elle est associée avec les lames d'un tablier en aluminium laqué.
  • Le maillon inférieur est fabriqué par un procédé de bi-injection de la matière.
  • L'épaisseur du maillon supérieur et d'au moins un maillon intermédiaire entre le maillon supérieur et le maillon inférieur est inférieure à l'épaisseur de deux bagues entre lesquelles le verrou est intercalé et qui lient le verrou de liaison à l'arbre d'enroulement.
According to advantageous but not mandatory aspects of the invention, a link lock may incorporate one or more of the following features, taken in any technically permissible combination:
  • The lower link is able to lock the assembly of the connection profile with the upper blade of the deck.
  • The connection profile has a fastening means to the upper blade of the deck.
  • The attachment means includes a hook which is carried by the connecting profile and which is adapted to catch on a loop carried by the upper blade of the deck.
  • The space between the lower link and the link profile, in mounted configuration of the link profile on the lower link, is smaller than the opening diameter of the loop so that the loop can not fall out of the profile of the link. link.

Sur les figures 1 à 7 est représenté un verrou de liaison 100 conçu pour atteler un tablier 300 à un arbre d'enroulement 200 d'un volet roulant. Ce verrou de liaison 100 peut également, comme suggéré par son nom, assurer une fonction de verrou du volet, c'est-à dire empêcher de remonter le volet en forçant depuis le bas vers le haut du tablier 300. En pratique, des maillons articulés 102 compris dans le verrou de liaison se bloquent une fois qu'ils sont alignés selon la direction verticale du volet, c'est-à-dire quand le volet est complètement déroulé.On the Figures 1 to 7 there is shown a link lock 100 designed to couple an apron 300 to a winding shaft 200 of a roller shutter. This connection lock 100 can also, as suggested by its name, provide a latch function of the flap, that is to say prevent the flap from being raised by forcing from the bottom to the top of the deck 300. In practice, links hinges 102 included in the link lock lock once they are aligned in the vertical direction of the flap, that is to say when the flap is fully unwound.

Comme représenté figure 1, un verrou de liaison 100 comprend plusieurs maillons articulés 102 autour d'un axe X102 qui, en configuration monté du verrou sur l'arbre d'enroulement 200, est parallèle à l'axe longitudinal de l'arbre d'enroulement 200. Ces maillons articulés 102 sont de la forme d'une portion d'anneau à profil circulaire. On distingue un maillon supérieur 104, comportant une broche de liaison 106 s'étendant selon un axe parallèle à l'axe X102, un maillon inférieur 108, de plus grande largeur, largeur notée L108 prise selon un axe parallèle à l'axe X102 et des maillons intermédiaires 103. Le nombre de maillons 103 intermédiaires évolue de 0 à 3 en fonction du diamètre d'enroulement final, faisant ainsi évoluer la distance entre l'arbre d'enroulement et la coulisse du volet roulant.As shown figure 1 a link lock 100 comprises a plurality of articulated links 102 about an axis X102 which, in the mounted configuration of the lock on the winding shaft 200, is parallel to the longitudinal axis of the winding shaft 200. Articulated links 102 are in the form of a circular profile ring portion. One distinguishes an upper link 104, having a connecting pin 106 extending along an axis parallel to the axis X102, a lower link 108, of greater width, width denoted L108 taken along an axis parallel to the axis X102 and Intermediate links 103. The number of intermediate links 103 changes from 0 to 3 depending on the final winding diameter, thereby changing the distance between the winding shaft and the shutter slide.

Le maillon supérieur 104 et les maillons intermédiaires 103 ont une épaisseur e1. Le maillon inférieur 108 inclut une fente traversante 105, s'étendant selon une largeur L108 du maillon inférieur 108, largeur prise selon un axe X108, s'étendant le long du maillon inférieur 108, selon un axe parallèle à l'axe X108.The upper link 104 and the intermediate links 103 have a thickness e1. The lower link 108 includes a through slot 105, extending along a width L108 of the lower link 108, taken along an axis X108, extending along the lower link 108, along an axis parallel to the axis X108.

Le maillon inférieur 108 comprend au centre une languette flexible 112, de largeur L112, largeur prise selon un axe parallèle à l'axe X108. On définit un axe Z112 comme un axe perpendiculaire à l'axe X108 et tangent à la portion de cercle définie par le maillon inférieur 108, tangente prise à l'extrémité libre du maillon inférieur 108. De la même manière, on définit un axe Y112 comme un axe perpendiculaire à l'axe X108 et Z112. La languette 112 a sa plus grande dimension selon l'axe Z112 et sa plus faible dimension selon l'axe Y112. Ainsi, la direction de déformation préférentielle de la languette 112 est une direction D1 qui est une direction parallèle à l'axe Y112.The lower link 108 comprises in the center a flexible tongue 112, width L112, width taken along an axis parallel to the axis X108. An axis Z112 is defined as an axis perpendicular to the axis X108 and tangent to the portion of circle defined by the link lower 108, tangent taken at the free end of the lower link 108. In the same way, an axis Y112 is defined as an axis perpendicular to the axis X108 and Z112. The tongue 112 has its largest dimension along the axis Z112 and its smallest dimension along the axis Y112. Thus, the direction of preferential deformation of the tongue 112 is a direction D1 which is a direction parallel to the axis Y112.

Au regard de la figure 2, un profil de liaison 110 s'étend selon un axe X110. Le profil de liaison 110 a une forme, en section transversale, en partie complémentaire de la fente 105. Le profil de liaison 110 porte en outre un crochet 114 en forme de J, centré sur un axe X114, parallèle à l'axe X110 et de diamètre d'ouverture Φ114. Le profil de liaison 110 contient une ouverture 116, de largeur L116 au centre du profil de liaison 110, centre de la dimension prise selon la direction X110. Par ailleurs, le profil de liaison 110 a une longueur L110, sensiblement supérieure à la largeur L108 du maillon inférieur 108 et la largeur L116 de l'ouverture 116 est sensiblement égale à la largeur L112 de la languette 112.In view of the figure 2 a connection profile 110 extends along an axis X110. The connecting profile 110 has a shape, in cross section, partly complementary to the slot 105. The connection profile 110 also carries a J-shaped hook 114, centered on an axis X114, parallel to the axis X110 and opening diameter Φ114. The connection profile 110 contains an opening 116, of width L116 in the center of the connection profile 110, the center of the dimension taken in the direction X110. Furthermore, the connection profile 110 has a length L110, substantially greater than the width L108 of the lower link 108 and the width L116 of the opening 116 is substantially equal to the width L112 of the tongue 112.

L'assemblage du profil de liaison 110 avec le maillon inférieur 108 amène le verrou de liaison 100 dans la configuration de la figure 3. En effet, la fente 105 et le profil de liaison 110 ayant des formes en partie complémentaires, le profil de liaison 110 est apte à coulisser dans la fente 105 selon l'axe X110, les axes X110 et X108 sont alors confondus. La forme de la fente 105 est telle qu'une fois le profil de liaison 110 inséré dans la fente 105, le profil de liaison 110 est apte à coulisser uniquement selon l'axe X108. Lors de l'installation du profil de liaison 110 dans le maillon inférieur 108, il convient de tirer la languette 112 dans la direction D1, puis d'insérer le profil de liaison 110 dans la fente 105 prévue à cet effet jusqu'à ce que l'ouverture 122 arrive au même niveau axial, selon l'axe X108, que la languette 112. L'opérateur doit alors lâcher la languette 112, celle-ci effectuant alors un retour élastique dans le sens opposé à la direction D1 et vient se loger dans l'ouverture 116. La languette 112 bloque donc le mouvement de translation, selon l'axe X108, du profil de liaison 110 par rapport au maillon inférieur 108. Dans cette configuration, on note e2 la largeur de l'espace entre le profil de liaison 110 et le maillon inférieur 108, largeur prise selon un axe Y112, axe perpendiculaire à l'axe Z112 et à l'axe X108, et représentée figure 5.The assembly of the connection profile 110 with the lower link 108 brings the connection lock 100 into the configuration of the figure 3 . Indeed, the slot 105 and the connecting profile 110 having partially complementary shapes, the connection profile 110 is slidable in the slot 105 along the axis X110, the axes X110 and X108 are then merged. The shape of the slot 105 is such that once the connection profile 110 inserted in the slot 105, the connection profile 110 is able to slide only along the axis X108. During the installation of the connection profile 110 in the lower link 108, it is necessary to pull the tongue 112 in the direction D1, then insert the connection profile 110 in the slot 105 provided for this purpose until the opening 122 reaches the same axial level, along the axis X108, as the tongue 112. The operator must then release the tongue 112, the latter then performing a springback in the opposite direction to the direction D1 and comes to housed in the opening 116. The tongue 112 thus blocks the translational movement, along the axis X108, of the connection profile 110 with respect to the lower link 108. In this configuration, we note e2 the width of the space between the linkage profile 110 and the lower link 108, width taken along an axis Y112, axis perpendicular to the axis Z112 and the axis X108, and shown figure 5 .

Plus précisément, la vue en coupe représentée figure 5 montre bien que la languette 112 est bien logée dans l'ouverture 116.More specifically, the sectional view shown figure 5 shows that the tongue 112 is well housed in the opening 116.

La figure 6 permet de visualiser l'assemblage complet du verrou de liaison 110 avec un tablier 300, un arbre d'enroulement 200 et un jeu de bagues 202 associées.The figure 6 allows to visualize the complete assembly of the connection lock 110 with an apron 300, a winding shaft 200 and a set of associated rings 202.

Le tablier 300, comprend plusieurs lames 302, la lame supérieure 304, c'est-à-dire la lame destinée à être accrochée au profil de liaison 110, comporte sur l'extérieur une boucle 306, centrée sur un axe X306, parallèle à l'axe longitudinal de l'arbre d'enroulement 200 en configuration montée, et de diamètre d'ouverture Φ306. La valeur du diamètre Φ306 est sensiblement égale à la valeur du diamètre Φ114 du crochet 114, de manière à ce que le tablier 300 puisse s'accrocher au profil de liaison 110. Le fait d'utiliser une liaison par crochets permet d'accrocher des tabliers ayant plusieurs épaisseurs de lames et de permettre une articulation relative entre les pièces pour passer de la position enroulée sur le tube à la position complétement déroulée.The apron 300 comprises several blades 302, the upper blade 304, that is to say the blade to be attached to the connecting profile 110, has on the outside a loop 306, centered on an axis X306, parallel to the longitudinal axis of the winding shaft 200 in assembled configuration, and of opening diameter Φ306. The value of the diameter Φ306 is substantially equal to the value of the diameter Φ114 of the hook 114, so that the apron 300 can hook onto the connection profile 110. The fact of using a hook connection makes it possible to hook aprons having multiple thicknesses of blades and allow a relative articulation between the parts to move from the wound position on the tube to the fully unwound position.

Les bagues 202 sont enroulées autour de l'arbre d'enroulement 200 et sont solidaires de celui-ci grâce à des saillies 204 disposées sur la forme interne des bagues 202. Ces saillies 204 coopèrent avec des rainures longitudinales 206 de l'arbre d'enroulement 200 afin de bloquer la rotation des bagues 202 par rapport à l'arbre d'enroulement 200. Une vis de liaison est généralement disposée pour fixer les bagues 202 sur l'arbre d'enroulement 200. Le mode de réalisation de cet assemblage utilise des bagues 202 mais il existe un autre mode de réalisation, non représenté sur les figures, où il est possible de fixer le verrou de liaison 100 directement sur l'arbre d'enroulement 200. Par exemple par vissage à l'aide des 2 trous 105 positionnés dans le maillon 104.The rings 202 are wound around the winding shaft 200 and are secured thereto by projections 204 disposed on the inner shape of the rings 202. These projections 204 cooperate with longitudinal grooves 206 of the shaft. winding 200 to lock the rotation of the rings 202 relative to the winding shaft 200. A connecting screw is generally arranged to fix the rings 202 on the winding shaft 200. The embodiment of this assembly uses rings 202 but there is another embodiment, not shown in the figures, where it is possible to fix the link lock 100 directly on the winding shaft 200. For example by screwing with the 2 holes 105 positioned in the link 104.

L'arbre d'enroulement 200 est centré sur un axe X200, qui dans cette configuration, est sensiblement parallèle aux axes X104, X102 et X120. Les bagues 202, centrées sur un axe X202 et d'épaisseur e202, sont enfilées autour de l'arbre d'enroulement 200 de manière à ce que l'axe X202 et l'axe X200 soient confondus.The winding shaft 200 is centered on an axis X200, which in this configuration is substantially parallel to the axes X104, X102 and X120. The rings 202, centered on an axis X202 and of thickness e202, are threaded around the winding shaft 200 so that the axis X202 and the axis X200 coincide.

Le verrou de liaison 100 est intercalé entre les bagues 202, et est fixé aux bagues 202 au moyen d'une broche 106, non représentée surs les figures 1 à 7, et venant se loger de part et d'autre des perçages longitudinaux 208 des bagues 202. L'épaisseur e1 des maillons 102, hormis celle du maillon inférieur 108, est strictement inférieure à l'épaisseur e202 des bagues 202, ceci a pour avantage que le tablier 300 repose, lors des phases d'enroulement et de déroulement, de préférence sur les bagues 202 plutôt que sur le maillon supérieur 104 et sur les maillons intermédiaires 103 du verrou 100. En effet, les bagues 202 sont conçues pour marquer le moins possible les lames 302 du tablier 300, il est donc préférable que le tablier 300 repose sur les bagues 202 plutôt que sur les maillons 102, étant susceptibles de rayer les lames 302 du tablier 300.The link lock 100 is interposed between the rings 202, and is fixed to the rings 202 by means of a pin 106, not shown on the Figures 1 to 7 , and coming to be housed on either side of the longitudinal bores 208 of the rings 202. The thickness e1 of the links 102, except that of the lower link 108, is strictly less than the thickness e202 of the rings 202, this has the advantage that the deck 300 rests, during the winding and unwinding phases, preferably on the rings 202 rather than on the upper link 104 and on the intermediate links 103 of the lock 100. Indeed, the rings 202 are designed to mark the less possible the blades 302 of the deck 300, it is therefore preferable that the deck 300 rests on the rings 202 rather than the links 102, being likely to scratch the blades 302 of the deck 300.

En pratique, l'opérateur commence par enfiler les bagues 202 autour de l'arbre d'enroulement 200, puis fixe le verrou de liaison 100, alors désolidarisé du profil de liaison 110, aux bagues 202 et au moyen d'une broche de liaison 106, représentée à la figure 1 et 7, dans des perçages longitudinaux 208.In practice, the operator begins by threading the rings 202 around the winding shaft 200, then sets the link lock 100, then disconnected from the connection profile 110, to the rings 202 and by means of a connecting pin 106, shown in FIG. figure 1 and 7 , in longitudinal bores 208.

Il convient ensuite d'accrocher indépendamment le profil de liaison 110 au tablier 300 puis de glisser le profil de liaison 110 dans la fente 105 du maillon inférieur 108 et de le bloquer au moyen de la languette 112. En configuration assemblée du verrou de liaison 100 avec le tablier 300, la boucle 306 est coincée, ou enfermée, dans un espace E compris entre le crochet 114 du profil de liaison 110 et un doigt 108A du maillon inférieur 108. En effet, la largeur e2 de l'espace E laissé entre le profil de liaison 110 et le maillon inférieur 108 est strictement inférieur au diamètre d'ouverture Φ306. Le tablier 300 est alors coincé entre le profil de liaison 110 et le maillon inférieur 108 : la liaison entre le tablier 300 et l'arbre d'enroulement 200 est alors assurée et les axes X114 et X306 sont alors confondus.It is then necessary to hook the connection profile 110 to the apron 300 independently and then to slide the connection profile 110 into the slot 105 of the lower link 108 and to block it by means of the tongue 112. In assembled configuration of the connection lock 100 with the apron 300, the loop 306 is jammed, or enclosed, in a space E between the hook 114 of the connection profile 110 and a finger 108A of the lower link 108. Indeed, the width e2 of the space E left between the connection profile 110 and the lower link 108 is strictly less than the opening diameter Φ306. The apron 300 is then wedged between the connection profile 110 and the lower link 108: the connection between the deck 300 and the winding shaft 200 is then ensured and the X114 and X306 axes are then merged.

Lors de la désinstallation, l'opérateur commence par retirer le profil de liaison 110 du maillon inférieur 108, en tirant sur la languette 112 dans la direction D1 puis en le faisant glisser le long de l'axe X108. Une fois le profil de liaison 110 dégagé du maillon inférieur 108, il ne reste plus qu'à détacher transversalement, c'est-à-dire selon une direction perpendiculaire à l'axe X110, le profil de liaison 110 de la première lame 302 du tablier 300.During the uninstallation, the operator first removes the link profile 110 from the lower link 108, pulling the tab 112 in the direction D1 and then sliding it along the axis X108. Once the link profile 110 is clear of the lower link 108, it remains only to detach transversely, that is to say in a direction perpendicular to the axis X110, the connection profile 110 of the first blade 302. apron 300.

Un autre aspect de l'invention est l'utilisation d'une couche de matière plastique ayant un très bon coefficient de frottement au niveau de la surface extérieure 109 du maillon inférieur 108. Le maillon inférieur 108 est plus large que les autres car étant directement en contact avec le tablier 300, il subit des contraintes mécaniques fortes liées au poids du tablier 300. Du fait de sa dimension, le maillon inférieur 108 a une largeur supérieure à une distance d202 entre les bagues 202, distance prise selon un axe parallèle à l'axe X200 en configuration montée du verrou 100 sur l'arbre 200, le maillon inférieur 108 recouvre donc les bagues 202. Ainsi, lors de l'enroulement du tablier 300 autour de l'arbre d'enroulement 200 les lames 302 viennent en contact de la surface extérieure 109 du maillon inférieur 108, ce qui est susceptible de rayer les lames 302 dans le temps. Ainsi, le maillon inférieur 108 est bi-matière : la matière sur le côté intérieur du maillon inférieur 108, c'est-à-dire orientée vers l'arbre d'enroulement 200 en configuration montée, est par exemple un polyamide chargé de fibres de verre permettant d'apporter de la résistance mécanique au maillon 108 et une peau en polyamide, (ou tout matériau à bon coefficient de frottement, disposée sur la surface extérieure 109 du maillon inférieur 108. Cette peau a un très bon coefficient de frottement de manière à ce que les lames 302 du tablier 300 ne soient pas rayées par le maillon 108 lors de l'enroulement du volet. La fabrication du maillon inférieur 108 est réalisée par une technique de bi-injection.Another aspect of the invention is the use of a plastic layer having a very good coefficient of friction at the outer surface 109 of the lower link 108. The lower link 108 is wider than the others since it is directly in contact with the deck 300, it undergoes strong mechanical stresses related to the weight of the deck 300. Because of its size, the lower link 108 has a width greater than a distance d202 between the rings 202, distance taken along an axis parallel to the axis X200 in mounted configuration of the latch 100 on the shaft 200, the lower link 108 thus covers the rings 202. Thus, during the winding of the deck 300 around the winding shaft 200 the blades 302 come into contact of the outer surface 109 of the lower link 108, which is likely to scratch the blades 302 in time. Thus, the lower link 108 is bi-material: the material on the inner side of the lower link 108, that is to say oriented towards the winding shaft 200 in mounted configuration, is for example a fiber filled polyamide of glass to provide mechanical strength to the link 108 and a polyamide skin, (or any material with a good coefficient of friction, disposed on the outer surface 109 of the lower link 108. This skin has a very good coefficient of friction of so that the blades 302 of the deck 300 are not scratched by the link 108 when the winding of the shutter. The manufacture of the lower link 108 is performed by a bi-injection technique.
