Abstract

The shutter rolls on to a shaft with its ends held up by supporting members joined by coupling elements (8) to lateral slideways (7) in which the shutter edges move as the shutter goes up and down. Each of the coupling elements comprises a connecting piece (13) with its lower end (14) engaged with the upper end of a slideway (7), while its upper end (24) has a support for the shaft and forms an extension to the lateral supporting member of the doorway or window aperture. Each coupling element (8) is made from a rigid central core embedded by over-moulding or other means, in an outer sleeve of a supple synthetic material. The core can be, for example, an I-section metal bar.

Description

L'invention a trait à un volet roulant pour porte, fenêtre ou analogue, comprenant un arbre sur lequel s'enroule un tablier et qui est maintenu, à ses extrémités, par des joues supports coopérant, par l'intermédiaire de moyens de liaison, avec des coulisses latérales dans lesquelles sont à même de se déplacer les extrémités latéralres dudit tablier.The invention relates to a rolling shutter for a door, window or the like, comprising a shaft on which an apron is wound and which is held, at its ends, by cooperating supporting cheeks, by means of connection means, with lateral slides in which the lateral ends of said apron are able to move.

La présente invention trouvera son application dans le domaine des volets roulants.The present invention will find its application in the field of roller shutters.

L'on connaît déjà un certain nombre de volets roulants répondant à la description ci-dessus. Plus particulièrement, un volet roulant comporte, habituellement, un arbre sur lequel et duquel s'enroule et se déroule un tablier composé d'une juxtaposition de lames reliées les unes aux autres à l'aide de moyens d'articulation appropriés. Cet arbre est maintenu, à ses extrémités, par des paliers ou analogues équipant des joues supports. Celles-ci peuvent être fixées, directement, sur la maçonnerie, mais elles peuvent, aussi, être rapportées à l'aide de moyens de liaison appropriés, aux coulisses latérales qui s'étendent, verticalement, de part et d'autre de l'embrasure correspondant à la porte, fenêtre ou analogue. En fait, dans ces coulisses latérales, se déplacent les extrémités latérales des lames correspondant au tablier, en cours de déploiement ou de repliement de ce dernier. Ainsi, une coulisse latérale emprunte, fréquemment, la forme d'un profilé en «U» comprenant deux ailes s'étendant parallèlement depuis un fond et entre lesquelles viennent se situer lesdites extrémités des lames. Très fréquemment, un cloisonnement intermédiaire, parallèle au fond, délimite un canal vertical dans l'extrémité supérieure duquel est insérée, en partie, une patte de liaison constituant, substantiellement, les moyens de liaison venant relier une joue support à ladite coulisse latérale.A number of roller shutters are already known which correspond to the above description. More particularly, a rolling shutter usually comprises a shaft on which and from which a deck is rolled up and unrolled, composed of a juxtaposition of slats connected to each other by means of appropriate articulation means. This shaft is held at its ends by bearings or the like fitted to support cheeks. These can be fixed directly to the masonry, but they can also be attached, using appropriate connecting means, to the side slides which extend, vertically, on either side of the recess corresponding to the door, window or the like. In fact, in these side slides, move the lateral ends of the blades corresponding to the deck, during deployment or folding of the latter. Thus, a lateral slide often takes the form of a "U" profile comprising two wings extending parallel from a bottom and between which are located said ends of the blades. Very often, an intermediate partition, parallel to the bottom, delimits a vertical channel in the upper end of which is inserted, in part, a connecting lug constituting, substantially, the connecting means coming to connect a support cheek to said lateral slide.

Selon un premier mode de réalisation connu, la patte de liaison est en forme d'une équerre dont la branche verticale vient s'insérer dans ladite coulisse latérale et y est immobilisée par des moyens de fixation, tels que vis ou analogues. Par ailleurs, la joue support comporte, dans ces conditions, dans sa partie inférieure horizontale, soit une glissière, soit des passants destinés à être engagés sur la branche horizontale de ladite patte de liaison en équerre.According to a first known embodiment, the connecting tab is in the form of a square whose vertical branch is inserted into said lateral slide and is immobilized there by fixing means, such as screws or the like. Furthermore, the support cheek has, under these conditions, in its lower horizontal part, ie a slide, or passers-by intended to be engaged on the horizontal branch of said connecting bracket at an angle.

Une autre solution consiste à réaliser cette patte de liaison de manière rectiligne dont la partie inférieure est, tout comme précédemment, immobilisée dans la coulisse, tandis que sur sa partie supérieure sont engagés les passants ou la glissière situés, dans de telles conditions, en bordure verticale avant de la joue support.Another solution consists in making this connecting tab in a rectilinear manner, the lower part of which is, as before, immobilized in the slide, while on its upper part are engaged the passers-by or the slide located, under such conditions, at the edge vertical front of the support cheek.

Ces solutions présentent, toutes deux, un certain nombre d'inconvénients du point de vue de leur tenue mécanique. Ainsi, les pattes de fixation, qu'elles soient en équerre ou rectilignes, se présentent sous forme de plats métalliques de sorte que, très fréquemment, leur rigidité est insuffisante pour supporter, intégralement, le poids du tablier, celui de l'arbre d'enroulement et, le cas échéant, le caisson contenant ce mécanisme. Aussi, il est usuel de soulager le poids supporté par les joues supports par des jambes de force fixées, par exemple, sur la maçonnerie. Ceci, bien entendu, complique sérieusement la procédure de montage du volet roulant.These solutions both have a certain number of drawbacks from the point of view of their mechanical strength. Thus, the fixing lugs, whether square or rectilinear, are in the form of metal dishes so that, very often, their rigidity is insufficient to fully support the weight of the deck, that of the shaft d 'winding and, if necessary, the box containing this mechanism. Also, it is usual to relieve the weight supported by the supporting cheeks by struts fixed, for example, on the masonry. This, of course, seriously complicates the procedure for mounting the roller shutter.

D'un autre côté, la souplesse relative des pattes de fixation permet, par déformation de ces dernières, d'ajuster la position angulaire des coulisses latérales par rapport à ces joues supports sachant que lesdites coulisses latérales sont rapportées, fréquemment, sur les tableaux de l'embrasure correspondant, à la porte, fenêtre ou analogue. Or, précisément, ces tableaux ne s'étendent pas, forcément, dans des plans parallèles auxdites joues supports.On the other hand, the relative flexibility of the fixing lugs makes it possible, by deformation of the latter, to adjust the angular position of the lateral slides relative to these support cheeks knowing that said lateral slides are reported, frequently, on the tables of the corresponding doorway, door, window or the like. However, precisely, these tables do not necessarily extend in planes parallel to said support cheeks.

Finalement, l'inconvénient majeur rencontré au travers des moyens de liaison connus et décrits ci-dessus, consiste en ce que la pose, à postériori, de l'ensemble arbre d'enroulement joue-support (ou caisson prééquipé de joues supports) sur des coulisses déjà fixées sur les tableaux de la porte, fenêtre ou analogue, n'est envisageable que si l'on dispose d'une place suffisante, soit horizontalememnt, soit verticalement, par rapport à l'extrémité supérieure des coulisses latérales. En effet, en cas d'usage de pattes de liaison en équerre, il doit être possible de reculer une joue support par rapport à l'extrémité supérieure de la coulisse d'une longueur au moins égale à la branche horizontale de cette patte de liaison. De même, lors d'un montage par le dessus l'on doit avoir la possibilité de soulever ladite joue support au-dessus de l'extrémité supérieure d'une coulisse latérale d'une longueur correspondant, soit à la partie saillante de la patte de liaison, soit à la partie introduite de cette dernière dans l'extrémité supérieure de ladite coulisse latérale. L'on peut, en effet, imaginer, tout particulièrement, dans ce dernier cas de figure, d'associer, préalablement, les pattes de fixation aux coulisses latérales ou inversement aux joues supports avant le montage de ces dernières.Finally, the major drawback encountered through known connection means and described above, consists in that the fitting, a posteriori, of the cheek-support winding shaft assembly (or box pre-equipped with support cheeks) on slides already fixed on the door, window or similar panels, can only be envisaged if there is sufficient space, either horizontally or vertically, relative to the upper end of the lateral slides. Indeed, when using connecting brackets at right angles, it must be possible to move back a supporting cheek relative to the upper end of the slide of a length at least equal to the branch horizontal of this connecting tab. Likewise, when mounting from above, it must be possible to lift said support cheek above the upper end of a lateral slide of a corresponding length, that is to say the projecting part of the tab. connecting, or to the part introduced from the latter into the upper end of said lateral slide. One can, in fact, imagine, very particularly, in the latter case, to associate, beforehand, the fixing lugs with the lateral slides or vice versa with the supporting cheeks before the mounting of the latter.

En fait, c'est précisément pour cette raison que l'on a tendance à réduire, au strict minimum, la longueur saillante d'une patte de liaison au-dessus d'une coulisse latérale pour, justement, limiter le mouvement vertical qu'il convient de conférer à une joue support en vue d'obtenir l'emboîtement. Or, il est évident que, plus la longueur de la patte de liaison est réduite, que ce soit en ce qui concerne sa partie introduite dans la coulisse ou celle logée dans la joue support, plus on affaiblit la tenue mécanique de cette liaison joue support - coulisse latérale.In fact, it is precisely for this reason that there is a tendency to reduce, to the strict minimum, the protruding length of a connecting tab above a lateral slide in order, precisely, to limit the vertical movement that it is necessary to give a cheek support in order to obtain nesting. However, it is obvious that, the more the length of the connecting lug is reduced, either as regards its part introduced into the slide or that housed in the support cheek, the more the mechanical strength of this support cheek connection is weakened - side slide.

La présente invention se veut à même de répondre à l'ensemble des problèmes précités en garantissant une liaison rigide entre une joue support et une coulisse latérale, liaison qui permet, pour autant, le réglage angulaire de cette dernière par rapport à ladite joue support. En fait, principalement, l'objet de la présente invention a pour but de faciliter le montage d'une joue support sur l'extrémité supérieure d'une coulisse latérale, ceci tout en réduisant au minimum l'encombrement procuré par un tel volet roulant, conforme à l'invention, au cours de ce montage.The present invention is intended to respond to all of the aforementioned problems by guaranteeing a rigid connection between a support cheek and a lateral slide, a connection which allows, however, the angular adjustment of the latter relative to said support cheek. In fact, mainly, the object of the present invention is to facilitate the mounting of a support cheek on the upper end of a lateral slide, this while minimizing the space provided by such a roller shutter , according to the invention, during this assembly.

A cet effet, l'invention concerne un volet roulant pour porte, fenêtre ou analogue, comprenant un arbre sur lequel s'enroule un tablier et qui est maintenu, à ses extrémités, par des joues supports coopérant, par l'intermédiaire de moyens de liaison, avec des coulisses latérales dans lesquelles se déplacent les extrémités latérales dudit tablier, caractérisé par le fait que lesdits moyens de liaison sont constitués par une patte de liaison dont la partie inférieure est engagée dans l'extrémité supérieure de la coulisse latérale, tandis que des moyens d'accrochage, équipant l'extrémité supérieure de la bordure avant de la joue support, viennent coopérer avec l'extrémité libre de la partie saillante correspondant à la patte de liaison de manière à contrebalancer le poids répercuté par ladite joue support sur cette patte de liaison sur laquelle elle prend appui au moins par l'intermédiaire de l'extrémité inférieure de sa bordure avant.To this end, the invention relates to a rolling shutter for a door, window or the like, comprising a shaft on which an apron is wound and which is held, at its ends, by cooperating supporting cheeks, by means of connection, with lateral slides in which the lateral ends of said deck move, characterized in that said connecting means are constituted by a connecting tab, the lower part of which is engaged in the upper end of the lateral slide, while hooking means, fitted to the upper end of the front edge of the support cheek, cooperate with the free end of the part protruding corresponding to the connecting tab so as to counterbalance the weight reflected by said support cheek on this connecting tab on which it bears at least through the lower end of its front edge.

Selon une autre caractéristique de l'invention, la partie inférieure de la patte de liaison est montée en rotation à l'intérieur de la coulisse latérale.According to another characteristic of the invention, the lower part of the connecting tab is rotatably mounted inside the lateral slide.

L'invention est exposée plus en détail dans la description qui va suivre et se rapportant au dessin joint en annexe représentant seulement un mode d'exécution.The invention is explained in more detail in the description which follows and relating to the attached drawing in the appendix representing only one embodiment.

Telle que représentée dans la figure 1 du dessin ci-joint, la présente invention est relative à un volet roulant 1 comprenant un arbre d'enroulement 2 d'un tablier 3 lequel est constitué par une juxtaposition de lames 4 reliées les unes aux autres à l'aide de moyens d'articulation appropriés. L'arbre d'enroulement 2 de ce volet roulant 1 est maintenu, à ses extrémités, par des paliers ou analogues équipant des joues supports 5. Bien entendu, l'ensemble de ce mécanisme du volet roulant 1 peut être contenu dans un caisson surmontant l'ouverture recevant la porte, fenêtre ou analogue.As shown in Figure 1 of the accompanying drawing, the present invention relates to a roller shutter 1 comprising a winding shaft 2 of an apron 3 which is constituted by a juxtaposition of blades 4 connected to each other at using appropriate means of articulation. The winding shaft 2 of this rolling shutter 1 is maintained at its ends, by bearings or the like fitted to the supporting cheeks 5. Of course, the whole of this mechanism of the rolling shutter 1 can be contained in a box surmounting the opening receiving the door, window or the like.

Te que visible plus particulièrement dans les figures 2 et suivantes, une joue support 5 s'étend au-dessus de l'extrémité supérieure 6 d'une coulisse latérale 7 dont elle est, par ailleurs, rendue solidaire par l'intermédiaire de moyens de liaison 8 conformes à l'invention.Te visible more particularly in Figures 2 and following, a support cheek 5 extends above the upper end 6 of a side slide 7 which it is, moreover, made integral by means of means link 8 according to the invention.

En fait, ces coulisses latérales 7 accueillent les extrémités latérales 9, 10 du tablier 3 et en assurent le guidage au cours de son déploiement ou encore de son repliement. Ainsi, ces coulisses latérales 7 sont, le cas échéant rapportées sur les montants du cadre dormant de la porte, fenêtre ou analogue, ou encore fixées sur les tableaux 11, 12 de la maçonnerie.In fact, these lateral slides 7 receive the lateral ends 9, 10 of the apron 3 and guide them during its deployment or even its folding. Thus, these lateral slides 7 are, if necessary attached to the uprights of the frame of the door, window or the like, or even fixed to the tables 11, 12 of the masonry.

Quant aux moyens de liaison 8 venant relier une joue support 5 à une coulisse latérale 7, ils sont constitués substantiellement, par une patte de liaison 13 dont la partie inférieure 14 est destinée à être introduite dans l'extrémité supérieure 6 de ladite coulisse latérale 7.As for the connection means 8 coming to connect a support cheek 5 to a lateral slide 7, they consist substantially, by a connection tab 13 whose lower part 14 is intended to be introduced into the upper end 6 of said lateral slide 7 .

A ce propos, il convient d'observer qu'une telle coulisse latérale 7 est constituée, habituellement, par un profilé de section approximative en forme de « U » comprenant un fond 15 d'où s'étendent deux ailes parallèles 16, 17 entre lesquelles viennent se déplacer, précisément, les extrémités latérales 9, 10 du tablier 3.In this regard, it should be observed that such a lateral slide 7 is usually constituted by a section of approximate section in the shape of a "U" comprising a bottom 15 from which extend two parallel wings 16, 17 between which move, precisely, the lateral ends 9, 10 of the deck 3.

Finalement, un cloisonnement intermédiaire 18 délimite, avec le fond 15, un canal vertical fermé 19 à l'intérieur de cette coulisse latérale 7. C'est précisément, dans l'extrémité supérieure de ce canal 19 que vient s'insérer la partie inférieure 14 de la patte de liaison 13.Finally, an intermediate partition 18 delimits, with the bottom 15, a closed vertical channel 19 inside this lateral slide 7. It is precisely, in the upper end of this channel 19 that the lower part is inserted 14 of the connecting lug 13.

Par ailleurs, sur l'extrémité libre 20 de la partie saillante 21 correspondant à cette patte de liaison 13 et s'étendant au-dessus de la coulisse latérale 7 vient s'accrocher la joue support 5. A cet effet et selon l'invention, cette dernière comporte, sensiblement à l'extrémité supérieure 22 de sa bordure avant 24 des moyens d'accrochage 25. Ceux-ci ont pour fonction de créer un point d'appui 26 du côté 27 de cette patte de liaison 13, opposée par rapport au côté où se situe cette joue support 5, de manière à contrebalancer le poids répercuté par cette dernière sur cette patte de liaison 13 sur laquelle elle prend appui au moins par l'intermédiaire de l'extrémité inférieure 29 de sa bordure avant 24.Furthermore, on the free end 20 of the projecting part 21 corresponding to this connecting tab 13 and extending above the lateral slide 7 is hooked the support cheek 5. For this purpose and according to the invention , the latter comprises, substantially at the upper end 22 of its front edge 24 of the hooking means 25. These have the function of creating a fulcrum 26 on the side 27 of this connecting lug 13, opposite with respect to the side where this support cheek 5 is located, so as to counterbalance the weight reflected by the latter on this connecting lug 13 on which it is supported at least by means of the lower end 29 of its front edge 24.

Il est évident qu'en maintenant, de cette manière, la joue support 5, simultanément, à son extrémité supérieure et à son extrémité inférieure, l'on obtienne une parfaite tenue mécanique de cette liaison joue support 5 - coulisse latérale 7.It is obvious that by maintaining, in this way, the support cheek 5, simultaneously, at its upper end and at its lower end, one obtains perfect mechanical strength of this connection cheek support 5 - lateral slide 7.

Préférentiellement, les moyens d'accrochage 25 constituent, également, des moyens de prise d'appui de la joue support 5 sur la patte de liaison 13.Preferably, the attachment means 25 also constitute means for taking support from the support cheek 5 on the connecting lug 13.

Ainsi, selon un mode de réalisation préférentiel, lesdits moyens d'accrochage 25 se présentent sous forme d'un prolongement 30 de la joue support 5 à l'extrémité supérieure 22 de la bordure avant 24. Dans la face inférieure 31 de ce prolongement 30 est aménagé un logement 32 apte à accueillir l'extrémité libre 20 de la patte de liaison 13. L'on comprend, ainsi, que pour amener les moyens d'accrochage 25 d'une joue support 5 en coopération avec la patte de liaison 13, il suffit de soulever ladite joue support 5, par rapport à sa position finale de montage, d'une hauteur 33 correspondant à la profondeur du logement 32.Thus, according to a preferred embodiment, said attachment means 25 are in the form of an extension 30 of the support cheek 5 at the upper end 22 of the front edge 24. In the lower face 31 of this extension 30 is provided a housing 32 adapted to receive the free end 20 of the connecting lug 13. It is thus understood that to bring the attachment means 25 of a support cheek 5 in cooperation with the connecting lug 13 , it suffices to lift said support cheek 5, with respect to its final mounting position, by a height 33 corresponding to the depth of the housing 32.

De la même manière, dans un plan horizontal, en dehors de l'encombrement général de la joue support 5, il doit être possible de déplacer cette dernière, par rapport à la coulisse latérale 7, sur une longueur correspondant, sensiblement, à la longueur 34 du prolongement 30 qui correspond, sensiblement, à l'épaisseur 35 d'une coulisse latérale 7.In the same way, in a horizontal plane, apart from the general dimensions of the support cheek 5, it must be possible to move the latter, relative to the lateral slide 7, over a length corresponding, substantially, to the length 34 of the extension 30 which corresponds, substantially, to the thickness 35 of a lateral slide 7.

Selon un mode de réalisation avantageux représenté en figure 3 et permettant d'améliorer encore, cette tenue mécanique de la liaison entre une joue support 5 et une coulisse latérale 7, dans le chant avant 36 de cette joue support 5 est aménagée une rainure 37 débouchant à son extrémité inférieure 38, tandis qu'à son extrémité supérieure 39, cette rainure 37 est délimitée par le prolongement 30 et donne accès, par conséquent, au logement 32. Préférentiellement, la largeur de cette rainure 37 est ajustée à la largeur de la patte de liaison 13, tout comme le logement 32 est de section ajustée à celle de cette dernière.According to an advantageous embodiment shown in FIG. 3 and making it possible to further improve, this mechanical strength of the connection between a support cheek 5 and a lateral slide 7, in the front edge 36 of this support cheek 5, a groove 37 opens out. at its lower end 38, while at its upper end 39, this groove 37 is delimited by the extension 30 and gives access, therefore, to the housing 32. Preferably, the width of this groove 37 is adjusted to the width of the connecting tab 13, just as the housing 32 is of section adjusted to that of the latter.

A ce propos, cette patte de liaison 13 peut être, soit rigide, soit comporter une âme centrale rigide 40 présentant une grande inertie. Ainsi, cette âme 40 peut être conçue, substantiellement, par un profilé métallique de section en forme de « I » tel que représenté dans la figure 4.In this regard, this connecting tab 13 can be either rigid, or include a rigid central core 40 having a high inertia. Thus, this core 40 can be designed, substantially, by a metal section section in the shape of an "I" as shown in FIG. 4.

De plus, cette âme centrale rigide 40 peut être noyée, par surmoulage ou autre, dans une enveloppe 40A conçue en un matériau synthétique plus souple. De cette manière, il est possible de diminuer, de manière appréciable, le bruit de fonctionnement d'un tel volet roulant 1. Tout particulièrement, l'on évite de répercuter sur les coulisses latérales 7 les éventuelles vibrations transmises aux joues supports 4 par des moyens de transmission motorisés.In addition, this rigid central core 40 can be embedded, by overmolding or the like, in an envelope 40A made of a more flexible synthetic material. In this way, it is possible to reduce, appreciably, the operating noise of such a rolling shutter 1. In particular, it is avoided to pass on the lateral slides 7 any vibrations transmitted to the supporting cheeks 4 by motorized transmission means.

Conformément à l'invention, la patte de liaison 13, tout particulièrement sa partie inférieure 14, est montée en rotation dans une coulisse latérale 7. Le but consiste à autoriser à cette coulisse latérale 7 de pivoter, selon un angle suffisant, par rapport à la patte de liaison 13 permettant d'ajuster la position angulaire de cette coulisse latérale 7 par rapport aux tableaux 11, 12 de la maçonnerie. Il se peut, en effet, qu'en raison des tolérances dans le domaine de la construction, ces tableaux 11, 12 ne soient pas totalement d'équerre au plan du volet roulant et, par conséquent, parallèles aux joues supports 5.According to the invention, the connecting lug 13, in particular its lower part 14, is rotatably mounted in a lateral slide 7. The aim is to allow this lateral slide 7 to pivot, at a sufficient angle, relative to the connecting lug 13 for adjusting the angular position of this lateral slide 7 relative to the tables 11, 12 of the masonry. It may be, in fact, that due to tolerances in the field of construction, these tables 11, 12 are not completely square to the plane of the rolling shutter and, consequently, parallel to the supporting cheeks 5.

Selon un mode de réalisation préférentiel, ladite coulisse latérale 7 comporte, au niveau de ses parois parallèles internes 41, 42 des portions de parois concaves 43, 44 avec lesquelles sont destinés à coopérer les bords verticaux convexes 45, 46 de la partie inférieure 14 correspondant à la patte de liaison 13.According to a preferred embodiment, said lateral slide 7 comprises, at its internal parallel walls 41, 42 portions of concave walls 43, 44 with which are intended to cooperate the convex vertical edges 45, 46 of the corresponding lower part 14 to the connecting lug 13.

Bien entendu, une telle partie inférieure 14 de la patte de liaison peut être immobilisée, verticalement, à l'intérieur du canal 19 de la coulisse latérale 7 à l'aide de moyens de fixation usuels, tels que vis, goupilles ou analogues.Of course, such a lower part 14 of the connecting tab can be immobilized, vertically, inside the channel 19 of the lateral slide 7 using conventional fixing means, such as screws, pins or the like.
