Description

La présente invention concerne le domaine du bâtiment, notamment l'aménagement des volets roulants sur les fenêtres des pièces d'immeubles et a pour objet un ensemble de caisson de volet roulant destiné à être monté sur une fenêtre avant pose, également dénommé volet monobloc, réalisé préférentiellement en polychlorure de vinyle (PVC).The present invention relates to the building sector, in particular the fitting of roller shutters on the windows of building parts and relates to a set of roller shutter boxes intended to be mounted on a window before installation, also called monobloc shutter, preferably made of polyvinyl chloride (PVC).

Il existe actuellement essentiellement deux types de caissons pour volets roulants, à savoir, d'une part, les caissons comportant des embouts fonctionnels à position variable dans un corps tubulaire, formé par assemblage de profilés longitudinaux en forme de planches et dont les extrémités sont fermées par des embouts à fonction esthétique et, d'autre part, des caissons comprenant un corps tubulaire formé comme ci-dessus et n'étant pourvus que d'embouts, à la fois fonctionnels et esthétiques, au niveau des extrémités dudit corps.There are currently essentially two types of boxes for rolling shutters, namely, on the one hand, the boxes comprising functional end pieces with variable position in a tubular body, formed by assembling longitudinal profiles in the form of boards and the ends of which are closed. by end pieces with an aesthetic function and, on the other hand, boxes comprising a tubular body formed as above and being provided only with end pieces, both functional and aesthetic, at the ends of said body.

Toutefois, ces deux types de caissons nécessitent, du fait de la très faible épaisseur des embouts fonctionnels, des interventions d'usinage sur un ou plusieurs des profilés formant le corps tubulaire afin de réaliser des passages pour les dispositifs de manoeuvre du tablier, éventuellement de types différents, tels que tige ou sangle, ce qui entraîne un montage progressif desdits dispositifs de manoeuvre, interdisant tout pré-montage.However, these two types of boxes require, because of the very small thickness of the functional end pieces, machining operations on one or more of the profiles forming the tubular body in order to make passages for the devices for operating the deck, possibly of different types, such as rod or strap, which leads to a progressive mounting of said operating devices, preventing any pre-mounting.

En outre, ces caissons existants, généralement conçus pour des montages dans l'épaisseur du mur ou "entre ébrasement", ne sont pas adaptés à des mises en oeuvre en applique, dans lesquelles lesdits caissons forment des saillies apparentes à l'intérieur des locaux, nécessitant des travaux de finition fastidieux entre la partie du caisson apparente et le plafond, longitudinalement et latéralement, aucune surface de fixation suffisante pour les caches n'étant prévue sur les éléments fixes dudit caisson.In addition, these existing boxes, generally designed for mounting in the thickness of the wall or "between splaying", are not suitable for surface-mounted applications, in which said boxes form visible projections inside the premises. , requiring tedious finishing work between the part of the visible box and the ceiling, longitudinally and laterally, no sufficient fixing surface for the covers being provided on the fixed elements of said box.

De ce fait, lesdits caches ou éléments de finition sont fréquemment collés sur la trappe de visite ou d'accès dudit caisson et doivent donc être remis en place et, le cas échéant, refaits à neuf après chaque démontage de ladite trappe, cette dernière faisant souvent appel pour son démontage à des outils tranchants entraînant des risques de détérioration et ne permettant pas d'accéder aux vis de fixation des différents éléments montés dans ledit caisson.As a result, said covers or finishing elements are frequently glued to the inspection or access hatch of said box and must therefore be replaced and, if necessary, refurbished after each dismantling of said hatch, the latter doing often called for its disassembly with sharp tools leading to risks of deterioration and not allowing access to the fixing screws of the various elements mounted in said box.

Par ailleurs, le montage des caissons existants sur les traverses dormantes supérieures des fenêtres est obtenu soit par vissage direct, ce qui, toutefois, rend ledit montage relativement long et fastidieux, soit par vissage d'un profilé puis par encliquetage ou clippage, du caisson sur ledit profilé, ladite liaison par clippage ou encliquetage étant verrouillée ou bloquée au moyen d'un profilé de maintien supplémentaire disposé à l'intérieur du local et assemblé par collage audit caisson.Furthermore, the mounting of the existing boxes on the upper sleepers of the windows is obtained either by direct screwing, which, however, makes said mounting relatively long and tedious, or by screwing a profile then by snap-fastening or clipping, of the box on said section, said connection by clipping or snap-fastening being locked or blocked by means of an additional retaining section arranged inside the room and assembled by bonding to said box.

Néanmoins, outre sa complexité de mise en oeuvre, ce dernier montage ne présente pas une grande résistance à la poussée du vent, qui est généralement opposée à la direction de l'encliquetage, ni au couple de basculement généré par la partie en porte-à-faux intérieur du caisson.However, in addition to its complexity of implementation, this latter assembly does not have a great resistance to the thrust of the wind, which is generally opposed to the direction of the latching, nor to the tilting torque generated by the door-to-door part. - false inside of the box.

La présente invention a notamment pour but de pallier l'ensemble des inconvénients précités.The present invention aims in particular to overcome all of the aforementioned drawbacks.

Elle a, en effet, pour objet un ensemble de caisson de volet roulant comprenant, d'une part, un corps tubulaire, préférentiellement de section rectangulaire ou carrée, constitué par des profilés supérieur, inférieur, extérieur et intérieur à double paroi, assemblés entre-eux par encliquetage au niveau de leurs bords longitudinaux et, d'autre part, deux embouts montés sur les deux extrémités dudit corps tubulaire et contre lesquels les profilés précités sont en appui, caractérisé en ce qu'au moins le rebord inférieur de l'un des embouts présente une largeur suffisante pour le montage des éléments de fixation et de transmission des organes de commande du tablier dudit volet roulant, en ce que le profilé supérieur comporte, au niveau de son bord longitudinal tourné vers l'intérieur, une surface de fixation d'un cache longitudinal, au moins partiellement masquée par le bord supérieur du profilé intérieur formant trappe d'accès et prolongée au niveau des embouts, et en ce que le profilé inférieur comporte une partie d'un dispositif d'accrochage mécanique par encastrement, s'étendant sur toute la longueur dudit profilé inférieur et coopérant, lors du montage, avec une partie complémentaire fixée sur la traverse dormante supérieure d'une fenêtre pour le montage dudit caisson de volet roulant.It has, in fact, for object a set of rolling shutter box comprising, on the one hand, a tubular body, preferably of rectangular or square section, constituted by upper, lower, exterior and interior profiles with double wall, assembled between them by snap-fastening at their edges longitudinal and, on the other hand, two end pieces mounted on the two ends of said tubular body and against which the aforementioned profiles are supported, characterized in that at least the lower edge of one of the end pieces has a width sufficient for the mounting of the fastening and transmission elements of the control members of the deck of said rolling shutter, in that the upper profile comprises, at its longitudinal edge facing inwards, a surface for fixing a longitudinal cover, at least partially hidden by the upper edge of the inner profile forming an access hatch and extended at the end pieces, and in that the lower profile comprises part of a mechanical fastening device by embedding, extending over the entire length of said lower profile and cooperating, during assembly, with a complementary part fixed to the upper dormant cross member of a window for mounting said housing rolling shutter sound.

Comme le montrent plus particulièrement les figures 2 à 5 des dessins annexés, l'ensemble de caisson de volet roulant comprend, d'une part, un corps tubulaire, préférentiellement de section rectangulaire ou carrée, constitué par des profilés 2 à 5 à double paroi, assemblés entre-eux par encliquetage au niveau de leurs bords longitudinaux et, d'autre part, deux embouts 6 montés sur les deux extrémités dudit corps tubulaire et contre lesquels les profilés précités sont en appui.As shown more particularly in Figures 2 to 5 of the accompanying drawings, the roller shutter box assembly comprises, on the one hand, a tubular body, preferably of rectangular or square section, formed by profiles 2 to 5 with double wall , assembled together by snap-fastening at their longitudinal edges and, on the other hand, two end pieces 6 mounted on the two ends of said tubular body and against which the aforementioned profiles are supported.

Conformément à l'invention, au moins le rebord inférieur 7 de l'un des embouts 6 présente une largeur suffisante pour le montage des éléments 8' et 9' de fixation et de transmission des organes de commande 8 et 9 du tablier dudit volet roulant et le profilé supérieur 2 comporte, au niveau de son bord longitudinal 2' tourné vers l'intérieur, une surface de fixation 10 d'un cache 11 longitudinal, au moins partiellement masquée par le bord supérieur 5' du profilé intérieur 5 formant trappe d'accès et prolongée au niveau des embouts 6, le profilé inférieur 3 comportant une partie 12 d'un dispositif d'accrochage mécanique par encastrement, s'étendant sur toute la longueur dudit profilé 3 et coopérant, lors du montage, avec une partie 12' complémentaire fixée sur la traverse dormante supérieure 13 d'une fenêtre pour le montage dudit caisson 1 de volet roulant.According to the invention, at least the lower edge 7 of one of the end pieces 6 has a sufficient width for mounting the elements 8 ′ and 9 ′ for fixing and transmitting the control members 8 and 9 of the apron of said roller shutter and the upper profile 2 comprises, at its longitudinal edge 2 ′ facing inwards, a fixing surface 10 of a longitudinal cover 11, at least partially masked by the upper edge 5 ′ of the internal profile 5 forming a hatch d access and extended at the end pieces 6, the lower profile 3 comprising a part 12 of a mechanical fastening device by embedding, extending over the entire length of said profile 3 and cooperating, during assembly, with a part 12 'complementary fixed on the upper sleeper 13 of a window for mounting said box 1 of roller shutter.

La surface de fixation 10 masquée peut avantageusement être obtenue, d'une part, en déportant la zone d'encliquetage 14 du profilé supérieur 2 avec le profilé intérieur 5 vers le bas, de manière à permettre l'aménagement d'une surface frontale 10 située au-dessus de ladite zone d'encliquetage 14 et en retrait par rapport à cette dernière et, d'autre part, en prolongeant le bord supérieur longitudinal 5' du profilé intérieur 5 formant trappe d'accès au-delà de la zone d'encliquetage avec le profilé supérieur 2.The concealed fixing surface 10 can advantageously be obtained, on the one hand, by moving the latching zone 14 of the upper profile 2 with the inner profile 5 downwards, so as to allow the development of a front surface 10 located above said latching zone 14 and recessed with respect to the latter and, on the other hand, by extending the longitudinal upper edge 5 ′ of the internal profile 5 forming an access hatch beyond the latching zone with the upper profile 2.

Cette disposition permet de mettre en place un cache 11 en forme de plaque allongée, découpé dans sa partie supérieure en fonction de la configuration du plafond contre lequel il est appliqué, le bord inférieur dudit cache pouvant présenter une position inclinée ou en biais par rapport au profilé supérieur 2, sans que ce défaut esthétique ne soit apparent ou visible de l'intérieur du local.This arrangement makes it possible to set up a cover 11 in the form of an elongated plate, cut in its upper part according to the configuration of the ceiling against which it is applied, the lower edge of said cover possibly having an inclined or oblique position relative to the upper section 2, without this aesthetic defect being apparent or visible from inside the room.

Afin de pouvoir réaliser également une finition esthétique entre les embouts 6 et le plafond, lesdits embouts 6 peuvent comporter un décrochement supérieur 15, s'étendant sur les faces apparentes intérieures desdits embouts 6 pour la mise en place d'un cache angulaire 16, ce dernier étant de niveau avec la surface de fixation 10 du profilé supérieur 2, pour sa portion adjacente audit profilé 2, et permettant ainsi de prolonger la surface de fixation 10 au-delà du profilé supérieur 2, sur toute la longueur de la face intérieure du caisson 1.In order to be able to also achieve an aesthetic finish between the end pieces 6 and the ceiling, said end pieces 6 may include an upper recess 15, extending over the visible interior faces of said end pieces 6 for the installation of an angular cover 16, this the latter being level with the fixing surface 10 of the upper profile 2, for its portion adjacent to said profile 2, and thus making it possible to extend the fixing surface 10 beyond the upper profile 2, over the entire length of the inner face of the box 1.

De plus, cette fixation des caches 11 et 16 autorise un démontage du profilé intérieur 5 formant trappe d'accès sans conséquence pour ces derniers.In addition, this fixing of the covers 11 and 16 allows the inner section 5 to be removed, forming an access hatch, without consequences for the latter.

Selon un mode de réalisation de l'invention, représentée aux figures 1 et 2 des dessins annexés, le dispositif d'accrochage mécanique est constitué, d'une part, par un élément profilé 12' de solidarisation monté sur la traverse dormante supérieure 13 de la fenêtre et comprenant notamment une aile inclinée d'ancrage 17 et une rampe 18 de positionnement et de guidage d'encastrement, opposée à ladite aile d'ancrage 17 et, d'autre part, par un renfoncement profilé longitudinal 12 de la paroi extérieure du profilé inférieur 3 délimité, d'un côté, par une fente 19 destinée à recevoir avec conjugaison de forme l'aile inclinée d'ancrage 17 et, du côté opposé, par une portion de paroi en biais 20 prenant appui sur la rampe 18 de l'élément profilé de solidarisation 12' lors de l'encastrement de ce dernier dans le renfoncement 12 longitudinal dudit profilé inférieur 3.According to one embodiment of the invention, shown in Figures 1 and 2 of the accompanying drawings, the mechanical fastening device consists, on the one hand, of a profiled element 12 'for fastening mounted on the upper sleeper cross member 13 of the window and comprising in particular an inclined anchoring wing 17 and a ramp 18 for positioning and guiding of embedding, opposite to said anchoring wing 17 and, on the other hand, by a longitudinal profiled recess 12 of the external wall of the lower profile 3 delimited, on one side, by a slot 19 intended to receive with conjugation of form the inclined anchoring wing 17 and, on the opposite side, by a portion of the oblique wall 20 bearing on the ramp 18 of the profiled securing element 12 ′ when the latter is embedded in the longitudinal recess 12 of said lower profile 3.

L'aile inclinée 17 constitue donc un point d'ancrage et de fixation solide du caisson 1, permettant une solidarisation rigide de ce dernier avec la traverse supérieure 13 de la fenêtre à l'encontre de la poussée exercée par le vent et du couple généré par la partie du caisson 1 en porte-à-faux.The inclined wing 17 therefore constitutes a solid anchoring and fixing point of the box 1, allowing a rigid connection of the latter with the upper cross member 13 of the window against the thrust exerted by the wind and the torque generated. by the part of the box 1 overhanging.

De plus, l'élément profilé de solidarisation 12' peut comporter une portion plane proéminente 21, s'étendant sur toute la longueur dudit élément profilé 12' et reposant contre une portion correspondante 22 de la paroi du renfoncement 12, ladite portion plane 21 et/ou ladite portion de paroi 22 étant munie d'un matériau adhésif 23 permettant un verrouillage de la liaison par encastrement entre le caisson 1 et la traverse dormante supérieure 13 concernée, notamment un verrouillage à l'encontre d'une poussée tendant à soulever ledit caisson 1.In addition, the profiled securing element 12 ′ may comprise a protruding planar portion 21, extending over the entire length of said profiled element 12 ′ and resting against a corresponding portion 22 of the wall of the recess 12, said planar portion 21 and / or said wall portion 22 being provided with an adhesive material 23 allowing a locking of the connection by embedding between the box 1 and the upper sleeper 13 concerned, in particular a locking against a thrust tending to lift said box 1.

Le montage de ce dernier sur la traverse dormante supérieure d'une fenêtre s'effectue par conséquent sans aucun outillage, par accrochage de l'aile inclinée 17 dans la fente 19, puis par encastrement du profilé 12' dans le renfoncement 12 lors de l'abaissement du caisson 1. En fin d'encastrement, le poids du caisson assure la compression du matériau adhésif 23 entre les portions 21 et 22, ce notamment durant sa phase de prise.The mounting of the latter on the upper dormant cross member of a window is therefore carried out without any tools, by hooking the inclined wing 17 in the slot 19, then by embedding the profile 12 'in the recess 12 during the lowering of the casing 1. At the end of embedding, the weight of the casing ensures the compression of the adhesive material 23 between the portions 21 and 22, this in particular during its setting phase.

Le dispositif d'accrochage mécanique par encastrement précité assure ainsi, sous l'action du poids propre du caisson 1, une solidarisation rigide de ce dernier sur la traverse 13, en particulier à l'encontre de la poussée du vent.The aforementioned mechanical fastening device by embedding thus ensures, under the action of the self-weight of the box 1, a rigid fastening of the latter on the cross member 13, in particular against the thrust of the wind.

Comme indiqué ci-dessus, l'un au moins des embouts 6 présente un rebord inférieur 7 de grande largeur permettant le montage de l'ensemble des éléments d'actionnement et de support du tablier du volet roulant sur un seul côté dudit embout 6, à savoir celui tourné vers l'intérieur du caisson 1.As indicated above, at least one of the end pieces 6 has a wide wide bottom edge 7 allowing the assembly of all of the actuating and support elements of the roller shutter deck on one side of said end piece 6, namely the one facing the inside of the box 1.

En vue de la fixation de la plaquette support 8' de la tige de manoeuvre 8 du treuil ou de l'arbre porteur 34 du tablier, ledit rebord inférieur 7 peut comporter des nervures de renforcement assurant une prise solide aux vis de fixation de ladite plaquette support 8'.With a view to fixing the support plate 8 ′ of the operating rod 8 of the winch or of the support shaft 34 of the deck, said lower flange 7 may include reinforcing ribs ensuring a solid grip on the fixing screws of said plate support 8 '.

Conformément à un mode de réalisation de l'invention représentée aux figures 1 et 6 des dessins annexés, l'un des embouts 6 comporte un dispositif 9' de passage de sangle de manoeuvre 9 obturable, composé d'un corps 24 de forme cylindrique, traversé, d'une part, par une fente 25 radiale, dans laquelle s'étendent au moins partiellement, de manière transversale, les extrémités libres des poils d'une brosse 26 implantée dans l'une des parois délimitant ladite fente 25 et disposé, d'autre part, dans un logement 27 adapté, ouvert vers l'intérieur du caisson 1 et vers l'extérieur de ce dernier et ménagé dans le rebord inférieur 7 de l'embout 6 considéré, ledit corps 24 de forme cylindrique pouvant être disposé, lors de sa mise en place sur ledit embout 6, soit dans une des deux positions d'obturation possibles, soit en position de passage de sangle 9.In accordance with an embodiment of the invention shown in FIGS. 1 and 6 of the appended drawings, one of the end pieces 6 comprises a device 9 ′ for passing the closable operating strap 9, composed of a body 24 of cylindrical shape, crossed, on the one hand, by a radial slot 25, in which extend at least partially, transversely, the free ends of the bristles of a brush 26 implanted in one of the walls delimiting said slot 25 and arranged, on the other hand, in a suitable housing 27, open towards the inside of the box 1 and towards the outside of the latter and formed in the lower edge 7 of the end piece 6 considered, said body 24 of cylindrical shape being able to be disposed , when it is placed on said endpiece 6, either in one of the two possible closing positions, or in the strap passage position 9.

Ledit corps 24 de forme cylindrique peut être pourvu de deux protubérances radiales extérieures opposées 28 et 28', adaptées pour l'obturation de l'ouverture extérieure du logement 27 recevant ledit corps 24, à savoir, l'une pour une obturation de niveau avec la paroi extérieure du rebord inférieur 7 de l'embout 6 considéré et l'autre pour une obturation avec recouvrement de ladite ouverture extérieure, au moyen d'une plaquette de recouvrement 28'' de ladite ouverture disposée à l'extrémité de ladite protubérance 28'. Le corps de forme cylindrique 24 pourra ainsi, en fonction de la présence ou de l'installation ultérieure d'une sangle de manoeuvre 9, être positionné dans l'une des trois positions possibles précitées.Said body 24 of cylindrical shape can be provided with two opposite external radial protrusions 28 and 28 ′, suitable for closing the external opening of the housing 27 receiving said body 24, namely, one for level filling with the outer wall of the lower edge 7 of the end piece 6 considered and the other for a closure with covering of said external opening, by means of a covering plate 28 '' of said opening arranged at the end of said protuberance 28 '. The cylindrical body 24 may thus, depending on the presence or subsequent installation of an operating strap 9, be positioned in one of the three possible positions mentioned above.

Afin d'augmenter la stabilité mécanique et les caractéristiques d'isolation du caisson 1, il peut être prévu qu'au moins les profilés supérieur 2 et inférieur 3 présentent des parois internes à conformation non planes, dont certaines portions de forme concaves épousent le pourtour extérieur du rouleau formé par le tablier enroulé, de manière à déporter lesdites parois internes au plus près dudit rouleau.In order to increase the mechanical stability and the insulation characteristics of the casing 1, it can be provided that at least the upper 2 and lower 3 sections have internal walls with non-planar conformation, some portions of concave shape matching the periphery outside of the roller formed by the rolled up apron, so as to offset said internal walls as close as possible to said roller.

Cette disposition permet d'obtenir une section maximale pour les profilés supérieur 2 et inférieur 3, sans perte d'enroulement, aboutissant à une stabilité mécanique maximale pour ces derniers et ménageant des lames d'air isolantes de dimensions élevées entre les parois internes et externes desdits profilés 2 et 3.This arrangement makes it possible to obtain a maximum section for the upper 2 and lower 3 sections, without loss of winding, resulting in maximum mechanical stability for the latter and providing insulating air spaces of large dimensions between the internal and external walls. of said sections 2 and 3.

En vue de rigidifier la partie inférieure du caisson 1 et notamment la liaison avec la traverse dormante supérieure 13 de la fenêtre, il est prévu un profilé de renfort métallique 29, préférentiellement d'une masse relativement importante, positionné sur la paroi interne du profilé inférieur 3, par accrochage et encliquetage, et pouvant former, en outre, avec ce dernier un réservoir de récupération longitudinal, après étanchéification au niveau des zones de jonction avec les embouts 6, ledit réservoir présentant un bord latéral intérieur 29' plus élevé que le bord latéral extérieur.In order to stiffen the lower part of the box 1 and in particular the connection with the upper dormant cross member 13 of the window, there is provided a metal reinforcing profile 29, preferably of a relatively large mass, positioned on the internal wall of the lower profile. 3, by hooking and snap-fastening, and capable of forming, in addition, with the latter a longitudinal recovery tank, after sealing at the junction zones with the end pieces 6, said tank having an inner lateral edge 29 'higher than the edge lateral exterior.

Ce profilé de renfort métallique 29 permet ainsi d'augmenter également l'inertie du caisson 1 et la stabilité de son assise sur la fenêtre.This metal reinforcing profile 29 thus also increases the inertia of the box 1 and the stability of his seat on the window.

Le réservoir constitué comme décrit ci-dessus permet de récupérer l'eau s'écoulant d'un tablier enroulé à l'état mouillé et, du fait de sa configuration, assure un déversement d'un trop plein éventuel sur l'extérieur de la fenêtre à travers la fente de passage du tablier.The reservoir constituted as described above makes it possible to recover the water flowing from an apron wound in the wet state and, because of its configuration, ensures a possible overflow spillage on the outside of the window through the apron passage slot.

Selon une autre caractéristique préférée de l'invention, le profilé supérieur 2 peut comporter au niveau de son bord extérieur une aile 30 s'étendant vers le bas, sous la zone d'assemblage 30' par encliquetage avec le profilé extérieur 4, contre la paroi externe de laquelle repose une portion de la paroi interne dudit profilé extérieur 4, un matériau adhésif 31, tel qu'une bande adhésive double-face mise en place lors de l'extrusion du profilé supérieur, assurant un liaisonnement entre les deux parois en contact et stabilisant le profilé extérieur 4, notamment la partie basse de ce dernier, en particulier contre les effets du vent.According to another preferred characteristic of the invention, the upper profile 2 can comprise, at its outer edge, a wing 30 extending downward, under the assembly zone 30 ′ by snap-fastening with the outer profile 4, against the outer wall of which rests a portion of the inner wall of said outer profile 4, an adhesive material 31, such as a double-sided adhesive strip put in place during the extrusion of the upper profile, ensuring a bonding between the two walls in contact and stabilizing the external profile 4, in particular the lower part of the latter, in particular against the effects of wind.

Afin de garantir un assemblage solide des profilés 2 à 5 sur les embouts 6 et une étanchéité maximale au niveau de leurs zones de jonction, le contact entre les profilés supérieur 2, extérieur 4 et intérieur 5, d'une part, et les embouts 6, d'autre part, est réalisé au moyen de surfaces d'appui entre les bords latéraux des parois externes et internes desdits profilés 2, 4 et 5 et des nervures correspondantes desdits embouts 6, le contact entre le profilé inférieur 3 et les embouts 6 étant réalisé par emboîtement partiel des bords latéraux extrêmes dudit profilé inférieur 3 dans des rainures correspondantes ménagées dans lesdits embouts 6, ces contacts étant verrouilés par l'intermédiaire de moyens de fixation, tels que par exemples des vis, au moins au niveau des angles dudit caisson 1, sauf en ce qui concerne le profilé intérieur.In order to guarantee a solid assembly of the profiles 2 to 5 on the end pieces 6 and a maximum seal at their junction zones, the contact between the upper 2 profiles, exterior 4 and interior 5, on the one hand, and the end pieces 6 , on the other hand, is produced by means of bearing surfaces between the lateral edges of the external and internal walls of said sections 2, 4 and 5 and corresponding ribs of said end pieces 6, the contact between the lower section 3 and the end pieces 6 being produced by partial interlocking of the extreme lateral edges of said lower section 3 in corresponding grooves made in said end pieces 6, these contacts being locked by means of fixing means, such as for example screws, at least at the angles of said box 1, except for the inner profile.

Comme le montrent les figures 1 à 3 et 7 des dessins annexés, le guidage du tablier peut être assuré préférentiellement, d'une part, lors de son entrée dans le caisson 1, par des rampes latérales 32 solidaires des embouts 6 et/ou avantageusement par un ou des guides profilés 33 montés par encliquetage sur la face avant du profilé inférieur 3 et, d'autre part, en cours d'enroulement sur l'arbre porteur 34, par des plaques métalliques latérales 35, épousant sensiblement le contour de la section interne dudit caisson 1 et fixées, au moyen de vis, soit sur la paroi de fond 37 des embouts 6, soit sur des écarteurs 36, à une distance éventuellement réglable de ladite paroi de fond 37, lesdites plaques de guidage 35 comportant un prolongement inférieur 35' s'étendant dans la zone des rampes latérales 32 et formant un bossage ou bombement pour l'appui et le guidage latéral du tablier lors de son entrée dans le caisson 1.As shown in Figures 1 to 3 and 7 of accompanying drawings, the guiding of the apron can preferably be ensured, on the one hand, when it enters the box 1, by lateral ramps 32 secured to the end pieces 6 and / or advantageously by one or more profiled guides 33 mounted by snap-fastening on the front face of the lower section 3 and, on the other hand, during winding on the support shaft 34, by lateral metal plates 35, substantially following the contour of the internal section of said box 1 and fixed, by means of screw, either on the bottom wall 37 of the end pieces 6, or on spacers 36, at a possibly adjustable distance from said bottom wall 37, said guide plates 35 having a lower extension 35 'extending in the area of the ramps lateral 32 and forming a boss or bulge for the support and lateral guidance of the deck when it enters the box 1.

Les guides profilés 33 permettent, en cas de mise en place, un guidage des lames du tablier sur toute leur longueur, plusieurs guides profilés 33, de longueur finie, pouvant être disposés, avec des espacements adaptés, à des endroits quelconques entre deux embouts 6 en étant encliquetés sur la face avant du profilé inférieur 3.The profiled guides 33 allow, in the event of installation, a guiding of the blades of the deck over their entire length, several profiled guides 33, of finite length, which can be arranged, with suitable spacings, at any places between two end pieces 6 by being snapped onto the front face of the lower profile 3.

Les rampes latérales 32 pourront constituer avec les prolongements inférieurs bombés 35' une fente de passage et de guidage pour les crochets latéraux des lames d'un tablier à crochets dits "anti-tempête".The lateral ramps 32 may constitute, with the curved lower extensions 35 ′, a passage and guide slot for the lateral hooks of the blades of an apron with so-called "storm-proof" hooks.

Pour le cas où les caissons 1 sont de grande longueur et renferment plusieurs tabliers côte à côte, il peut être prévu au moins un séparateur de tabliers (non représenté), disposé dans le corps tubulaire dudit caisson 1 à un emplacement quelconque entre les deux embouts 6, traversé par l'arbre porteur 34 et composé par l'assemblage de deux plaques de guidage 35 au niveau de leur face arrière, lesdites plaques 35 étant solidarisées aux profilés inférieur 3 et supérieur 2 par l'intermédiaire de languettes 38 au niveau de portions de parois internes 38' desdits profilés 2 et 3 situées à proximité du profilé intérieur 5 et accessibles, sans outillage spécial (tel qu'un tournevis coudé), lorsque ledit profilé intérieur 5 est enlevé, ce même lorsque l'arbre porteur 34 et le tablier sont en place.In the case where the boxes 1 are very long and contain several aprons side by side, there can be provided at least one apron separator (not shown), arranged in the tubular body of said box 1 at any location between the two end pieces 6, crossed by the carrier shaft 34 and composed by the assembly of two guide plates 35 at their rear face, said plates 35 being secured to the lower 3 and upper 2 sections by means of tongues 38 at the level of portions of internal walls 38 ′ of said sections 2 and 3 located near the internal section 5 and accessible, without special tools (such as an angled screwdriver), when said inner section 5 is removed, even when the support shaft 34 and the deck are in place.

Afin de faciliter l'accès à l'intérieur du caisson 1 et de permettre le remplacement de tout élément contenu dans ce dernier, le profilé intérieur 5, formant trappe d'accès, est monté de manière amovible par encliquetage sur les bords longitudinaux intérieurs 2' et 3' des profilés supérieur 2 et inférieur 3 et sur des crochets 6' correspondants des embouts 6 et recouvre la totalité de la face verticale intérieure dudit caisson 1, inclusivement celle des embouts 6 au moyen de caches d'extrémité présentant un léger rebord destiné à masquer les vis d'assemblage des profilés supérieur 2 et inférieur 3 avec les embouts 6 (non représentés), l'étanchéité entre lesdits embouts 6 et ledit profilé intérieur 5 étant réalisée par l'intermédiaire de joints à lèvre verticaux 39 fixés sur les faces verticales intérieures desdits embouts 6, contre lesquelles repose ledit profilé intérieur 5 après montage.In order to facilitate access to the interior of the housing 1 and to allow the replacement of any element contained therein, the interior profile 5, forming an access hatch, is removably mounted by snap-fastening on the interior longitudinal edges 2 'and 3' of the upper 2 and lower 3 sections and on hooks 6 'corresponding to the end pieces 6 and covers the entire inner vertical face of said box 1, including that of the end pieces 6 by means of end caps having a slight rim intended to hide the assembly screws of the upper 2 and lower 3 sections with the end pieces 6 (not shown), the seal between said end pieces 6 and said internal profile 5 being produced by means of vertical lip seals 39 fixed on the inner vertical faces of said end pieces 6, against which said inner section 5 rests after mounting.

Conformément à une autre caractéristique de l'invention, représentée aux figures 1 et 2 des dessins annexés, un profilé 40 en un matériau d'isolation thermique, épousant partiellement le contour extérieur du rouleau formé par le tablier enroulé, est mis en place, préférentiellement par encliquetage sur les profilés supérieur 2 et inférieur 3, dans l'ouverture existant avant installation du profilé intérieur 5, un espace libre 41 étant ménagé entre ledit profilé 40 d'isolation thermique et ledit profilé intérieur 5, pour autoriser la mise en place éventuelle d'une couche d'isolant phonique 42, collée par exemple sur le profilé intérieur 5.According to another characteristic of the invention, shown in Figures 1 and 2 of the accompanying drawings, a profile 40 of a thermal insulation material, partially matching the outer contour of the roll formed by the rolled apron, is preferably put in place by snap-fastening on the upper 2 and lower 3 profiles, in the opening existing before installation of the interior profile 5, a free space 41 is provided between said profile 40 for thermal insulation and said interior profile 5, to allow possible installation a layer of sound insulation 42, bonded for example on the interior profile 5.

Selon une caractéristique supplémentaire de l'invention, représentée partiellement aux figures 1 à 3 des dessins annexés, tous les assemblages par vis entre les profilés 2 à 4, les plaques de guidage 35 et des plaques 43 de support de treuil et d'arbres porteurs 34, d'une part, et les embouts 6, d'autre part, sont réalisés au niveau de nervures ou d'écarteurs 36, à distance de la paroi de fond 37 desdits embouts 6 et préférentiellement parallèlement à cette dernière, tout en étant disposés dans des endroits directement accessibles à travers l'ouverture obtenue après enlèvement du profilé intérieur 5 et, le cas échéant, d'un profilé 40 en un matériau d'isolation thermique.According to an additional characteristic of the invention, shown partially in Figures 1 to 3 of the accompanying drawings, all the screw connections between the sections 2 to 4, the guide plates 35 and the plates 43 for supporting the winch and the carrier shafts 34, on the one hand, and the end pieces 6, on the other hand, are produced at the level of ribs or spacers 36, at a distance from the bottom wall 37 of said end pieces 6 and preferably parallel to the latter, while being arranged in places directly accessible through the opening obtained after removal of the inner profile 5 and, where appropriate, of a profile 40 in a thermal insulation material.

Les seules vis de fixation mises en place par l'extérieur pourront éventuellement être celles assurant la solidarisation des extrémités des bords intérieurs 2' et 3' des profilés supérieur 2 et inférieur 3 sur les embouts 6, ces vis étant toutefois masquées par les caches d'extrémité du profilé intérieur 5 au moyen d'un rebord recouvrant une portion des faces latérales visibles des embouts 6 (non représentés).The only fixing screws put in place from the outside could possibly be those ensuring the joining of the ends of the inner edges 2 ′ and 3 ′ of the upper 2 and lower 3 sections on the end pieces 6, these screws however being masked by the covers end of the inner section 5 by means of a flange covering a portion of the visible side faces of the end pieces 6 (not shown).

La plaque 43 de support de treuil et d'arbre 34 porteur ou enrouleur pourra être munie d'une languette de fixation coudée autorisant une fixation déportée par rapport à la paroi de fond 37 de l'embout 6 considéré.The winch support plate 43 and carrier shaft 34 or reel may be provided with a bent fixing tab allowing a remote fixing relative to the bottom wall 37 of the end piece 6 considered.

Ainsi, il est non seulement aisé d'effectuer le montage de l'ensemble des éléments destinés à être disposés dans les embouts 6, en assurant un montage d'un seul côté sur lesdits embouts 6, mais également possible d'éviter toute mise en place de vis d'assemblage visibles sur les faces apparentes, à l'intérieur du local, du corps tubulaire du caisson 1 et desdits embouts 6.Thus, it is not only easy to carry out the assembly of all the elements intended to be arranged in the end pieces 6, by ensuring mounting on one side on said end pieces 6, but also possible to avoid any setting in place of visible assembly screws on the visible faces, inside the room, of the tubular body of the box 1 and of said end pieces 6.

Grâce à l'invention, il est donc possible de réaliser un ensemble de caisson de volet roulant dans lequel tous les éléments de support et de manoeuvre du tablier ou de l'arbre porteur 34 peuvent être prémontés dans les embouts 6, limitant de ce fait les opérations d'usinage sur les profilés longitudinaux 2 à 5 à de simples mises à la longueur, le montage desdits éléments de support et de manoeuvre et l'assemblage dudit caisson 1 n'entraînant aucune mise en place de vis de fixation apparentes.Thanks to the invention, it is therefore possible to produce a set of roller shutter boxes in which all the support and maneuvering elements of the deck or of the carrying shaft 34 can be pre-assembled in the end pieces 6, thereby limiting the machining operations on the longitudinal sections 2 to 5 to simple length cuts, the mounting said support and maneuvering elements and assembling said box 1 resulting in no fitting of visible fixing screws.

De plus, les nervures de rigidification structurelle des embouts 6 pourront être apparentes au niveau de leur partie insérée dans les murs et recouvertes par la paroi de fond 37 au niveau de leur partie apparente (figures 4 et 5).In addition, the structural stiffening ribs of the end pieces 6 may be visible at their part inserted into the walls and covered by the bottom wall 37 at their visible part (Figures 4 and 5).

En outre, les différentes caractéristiques de l'invention permettent d'obtenir un caisson 1 présentant, d'une part, une rigidité et une stabilité mécanique élevées, d'autre part, une étanchéité à l'eau et à l'air et une isolation thermique et phonique supérieures à celles des caissons de l'art antérieur, ce sans perte de volume d'enroulement pour le tablier et, enfin, un moyen de liaisonnement avec la fenêtre qui est facile et rapide à mettre en oeuvre et qui assure un positionnement sûr et stable dudit caisson 1.In addition, the various characteristics of the invention make it possible to obtain a box 1 having, on the one hand, a high rigidity and mechanical stability, on the other hand, a water and air tightness and a thermal and sound insulation superior to those of the boxes of the prior art, this without loss of winding volume for the deck and, finally, a means of bonding with the window which is easy and quick to implement and which ensures a safe and stable positioning of said box 1.

Par ailleurs, il est également possible, par la prévision d'une surface de fixation 10 telle que décrite ci-dessus, de recouvrir au moyen d'un cache 11 ou d'un couvre-joint standard, non recoupé, des interstices de largeurs variables pouvant exister entre le plafond et le dessus du caisson, ce tout en masquant les défauts de parallélisme entre ces derniers.Furthermore, it is also possible, by providing a fixing surface 10 as described above, to cover by means of a cover 11 or a standard, uncut joint cover, gaps of widths variables that may exist between the ceiling and the top of the box, while masking the lack of parallelism between the latter.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention selon la revendication 1.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings.
