Description

La présente invention concerne une porte sectionnale.The present invention relates to a sectional door.

On connaít déjà des portes sectionnales et on citera, à titre d'illustration, le document de brevet FR-A-2 467 952. Dans ce document, la porte sectionnale décrite est du type qui comprend essentiellement un vantail constitué d'une pluralité de panneaux articulés les uns par rapport aux autres, chacun desdits panneaux comportant des coulisseaux identiques prévus pour pouvoir coulisser le long de deux glissières respectivement prévues sur les côtés de la baie que ladite porte est destinée à fermer. Chacune desdites glissières présente une partie sensiblement verticale et une partie sensiblement horizontale à l'intérieur du local que ladite porte est destinée à fermer reliée entre elles par une partie courbée.We already know sectional doors and we will cite, by way of illustration, the patent document FR-A-2 467 952. In this document, the sectional door described is of the type which essentially comprises a leaf consisting of a plurality of panels hinged relative to each other, each of said panels comprising identical slides designed to be able to slide along two slides respectively provided on the sides of the bay that said door is intended to close. Each of said slides has a substantially vertical part and a part substantially horizontal inside the room that said door is intended to close connected together by a curved part.

Les glissières sont creuses et les coulisseaux sont pourvus de galets pour pouvoir rouler à l'intérieur desdites glissières.The slides are hollow and the slides are provided with rollers for being able to roll inside said slides.

Or, il s'avère qu'un tel arrangement de porte n'est pas nécessairement très sain du fait notamment de l'eau qui peut stagner à l'intérieur des glissières. De plus, les galets sont difficilement accessibles et sont donc difficiles à nettoyer.However, it turns out that such a door arrangement is not necessarily very healthy. in particular makes water which can stagnate inside the slides. In addition, the pebbles are difficult to access and therefore difficult to clean.

Le but de la présente invention est de proposer une porte sectionnale qui ne présente pas ces inconvénients.The object of the present invention is to propose a sectional door which does not not have these drawbacks.

A cet effet, une porte sectionnale selon la présente invention est caractérisée en ce que chacune desdites glissières est tubulaire et en ce que chacun desdits coulisseaux comprend des galets d'axes horizontaux se trouvant sensiblement dans le plan du panneau correspondant et prévus pour pouvoir rouler sur le tube constitutif de chaque glissière, au moins un galet se trouvant tourné, par rapport à ladite glissière, vers l'extérieur dudit local alors qu'au moins un autre galet se trouve tourné vers l'intérieur dudit local.To this end, a sectional door according to the present invention is characterized in that each of said slides is tubular and that each of said runners comprises rollers with horizontal axes located substantially in the plane of the corresponding panel and designed to be able to roll on the constituent tube of each slide, at least one roller being turned, relative to said slide, towards the outside of said room when at least one other roller is facing inside said room.

Dans l'exemple de réalisation représenté, ces deux parties de repos sont reliées entre elles à au moyen d'une partie courbée 33a, 33b. Chaque partie de repos fermé 31a, 31b est fixée, d'une part, sur une platine 34a, 34b au sol et, d'autre part, sur le montant (non représenté) de la baie que la porte ferme au moyen de supports 35a (35b est non visible sur la Fig. 1). Quant à chaque partie de repos ouvert 32a, 32b, elle est destinée à se trouver à l'intérieur du local fermé par la porte et elle est fixée au plafond du local fermé par la porte au moyen de supports 36a, 36b.Each slide 30a, 30b essentially consists of a rest part 31a, 31b in the closed position of the leaf 10 (called closed rest part), part generally substantially vertical (in reality, as will be understood later, this part 31a, 31b is slightly inclined from the inside towards the outside to allow better closing of the leaf 10 on its embrasure) and of a part of rest 32a, 32b in the open position of the leaf 10 (so-called open rest part), part which is, in the illustrated embodiment, substantially horizontal but which could be an extension of the previous game. In the example of illustrated embodiment, these two rest parts are connected to each other by means of a curved part 33a, 33b. Each closed rest part 31a, 31b is fixed, with a firstly, on a plate 34a, 34b on the ground and, secondly, on the upright (not shown) of the opening that the door closes by means of supports 35a (35b is not visible in Fig. 1). As for each open rest part 32a, 32b, it is intended to be at inside the room closed by the door and it is fixed to the ceiling of the room closed by the door by means of supports 36a, 36b.

    Comme on le comprendra aisément, par l'exercice d'une force verticale ascendante sur au moins l'un des panneaux 11 à 15, on peut faire coulisser l'ensemble desdits panneaux 11 à 15, par l'intermédiaire des coulisseaux 21a à 25a, 21b à 25b sur les glissières 30a et 30b, d'abord sur les parties de repos fermé 31a et 31b, puis sur les parties de repos ouvert 32a et 32b.As will be easily understood, by the exercise of a vertical force ascending on at least one of the panels 11 to 15, we can slide the assembly of said panels 11 to 15, via slides 21a to 25a, 21b to 25b on the slides 30a and 30b, first on the closed rest parts 31a and 31b, then on the open rest parts 32a and 32b.

    Lorsque l'ensemble des panneaux 11 à 15 est supporté par les parties de repos ouvert 32a et 32b, la porte sectionnale est ouverte.When all of the panels 11 to 15 are supported by the rest parts open 32a and 32b, the sectional door is open.

    Ensuite, lorsqu'elle est ouverte, par l'exercice d'une force horizontale tournée vers l'extérieur du local, on peut faire coulisser l'ensemble desdits panneaux 11 à 15 d'abord sur les parties de repos ouvert 32a et 32b puis sur les parties de repos fermé 3 la et 31b. Lorsque l'ensemble des panneaux 11 à 15 est supporté par les parties de repos fermé 31a et 31b (comme cela est représenté à la Fig. 1), la porte sectionnale est fermée.Then, when it is open, by the exercise of a horizontal force turned towards the outside of the room, it is possible to slide all of said panels 11 to 15 first on the open rest parts 32a and 32b then on the closed rest parts 3 la and 31b. When all of the panels 11 to 15 are supported by the parts of closed rest 31a and 31b (as shown in Fig. 1), the sectional door is closed.

    On notera que l'exercice des forces verticales ou horizontales peut se faire manuellement et, dans ce cas, au moins un panneau comporte par exemple une poignée appropriée (non représentée) ou, au contraire, de manière motorisée, par exemple au moyen d'un moteur électrique et un système, tel qu'une crémaillère, un câble sans fin, etc. (également non représentés). Cela n'est pas décrit plus en détail, dans la mesure où cela n'est pas l'objet de la présente invention.Note that the exercise of vertical or horizontal forces can be done manually and, in this case, at least one panel has for example a suitable handle (not shown) or, on the contrary, in a motorized manner, by example using an electric motor and a system, such as a rack, a endless cable, etc. (also not shown). This is not described in more detail, insofar as this is not the object of the present invention.

    Pour "alléger" le vantail 10, on a prévu, de chaque côté de la porte sectionnale, des moyens de compensation du poids desdits panneaux 11 à 15 constitués d'un moyen de rappel, tel qu'un ressort, un contrepoids, etc. Dans l'exemple de réalisatin représenté, chaque moyen de rappel est un ressort 40a, 40b qui est relié au vantail 10 par l'intermédiaire d'un système de mouflage 41a, 41b. Ce système de mouflage 41a, 41b est constitué, dans le mode de réalisation représenté à la Fig. 1, d'un jeu de poulies 42a, 42b fixé sur le montant de la baie et d'une poulie 43a, 43b à l'extrémité haute du ressort correspondant 40a, 40b. Un câble 44a, 44b est fixé sur le panneau bas 15, passe dans les réas des poulies 42a, 42b, puis dans le réa dans la poulie 41a pour venir se fixer au montant de la baie. L'extrémité basse de chaque ressort 40a, 40b est fixée sur la platine 34a, 34b correspondante.To "lighten" the leaf 10, there is provided, on each side of the sectional door, means for compensating for the weight of said panels 11 to 15 consisting of a return means, such as a spring, counterweight, etc. In the example of realization shown, each return means is a spring 40a, 40b which is connected to the leaf 10 via a hauling system 41a, 41b. This hauling system 41a, 41b is constituted, in the embodiment shown in FIG. 1, a set of pulleys 42a, 42b fixed on the upright of the rack and a pulley 43a, 43b at the upper end of the corresponding spring 40a, 40b. A cable 44a, 44b is fixed to the bottom panel 15, passes through the sheaves of the pulleys 42a, 42b, then through the sheave through the pulley 41a to come attach to the amount of the rack. The lower end of each spring 40a, 40b is fixed on the corresponding plate 34a, 34b.

    On comprendra que le ressort 40a, 40b exerce une force verticale ascendante sur le vantail 10 qui décroít avec le nombre de panneaux 11 à 15 qui se trouvent dans la position horizontale reposant sur les parties de repos ouvert 32a et 32b. En choisissant une raideur appropriée de chaque ressort 40a, 40b et en l'ajustant éventuellement au moyen de systèmes droite/gauche 45a, 45b, la force verticale exercée par les ressorts 40a, 40b compensent en grande partie le poids des panneaux 11 à 15 qui se trouvent en position verticale reposant sur les parties de repos fermé 31a et 31b.It will be understood that the spring 40a, 40b exerts an ascending vertical force on the leaf 10 which decreases with the number of panels 11 to 15 which are in the horizontal position resting on the open rest parts 32a and 32b. By choosing an appropriate stiffness of each spring 40a, 40b and possibly adjusting it to means of right / left systems 45a, 45b, the vertical force exerted by the springs 40a, 40b largely compensate for the weight of the panels 11 to 15 which are located in a vertical position resting on the closed rest parts 31a and 31b.

    On a représenté à la Fig. 2 un coulisseau 50 en position sur une glissière 30. Sur cette Fig. 2, on voit également la partie basse d'un panneau 101 et la partie haute d'un panneau 102. Le coulisseau 50 est par ailleurs fixé par exemple par vissage au panneau 102 par l'intermédiaire d'une platine 51.There is shown in FIG. 2 a slide 50 in position on a slide 30. In this FIG. 2, we can also see the lower part of a panel 10 1 and the upper part of a panel 10 2 . The slide 50 is also fixed for example by screwing to the panel 10 2 by means of a plate 51.

    On a représenté à la Fig. 3 le même coulisseau 50 mais coupé selon le plan III/III de la Fig. 2. On reconnaít, sur cette Fig. 3, la glissière 30 qui, selon une caractéristique de la présente invention, présente une section circulaire. Elle est ici constituée d'un tube à section circulaire. On reconnaít également le panneau 102 déjà représenté à la Fig. 2 ainsi que la platine 51. Les moyens de fixation de la platine 51 sur le panneau 102 ne sont pas représentés.There is shown in FIG. 3 the same slide 50 but cut along plane III / III of FIG. 2. We recognize, in this Fig. 3, the slide 30 which, according to a characteristic of the present invention, has a circular section. Here it consists of a circular section tube. We also recognize the panel 102 already shown in FIG. 2 as well as the plate 51. The means for fixing the plate 51 on the panel 10 2 are not shown.

    Le coulisseau 50 comprend en outre deux galets 52a et 52b qui sont montés sur une double chape 53 ( dite ci-après chape 53) de manière à pouvoir tourner librement tout en enserrant le tube constituant la glissière 30. Ces galets 52a et 52b sont situés de part et d'autre de la glissière 30, respectivement du côté tourné vers l'intérieur du local dans lequel la porte sectionnale est installée et du côté tourné vers l'extérieur de ce local, ceci lorsque le vantail 10 se trouve en position verticale.The slide 50 further comprises two rollers 52a and 52b which are mounted on a double yoke 53 (hereinafter called yoke 53) so that it can rotate freely while enclosing the tube constituting the slideway 30. These rollers 52a and 52b are located on either side of the slide 30, respectively on the side facing the interior of the room in which the sectional door is installed and on the outward side of this local, this when the leaf 10 is in a vertical position.

    Chaque galet 52 comprend donc deux parties tronconiques galbées 521 qui présentent un rayon de courbure égal au rayon du tube de la glissière 30 de manière à pouvoir reposer sur ce tube et qui sont placées de part et d'autre d'une partie en retrait, ici cylindrique également galbée avec un rayon de courbure inférieur à celui du tube de la glissière 30. De cette manière, chaque galet 52 roule sur le tube de la glissière 30 en ne prenant appui sur lui (par les parties 521) que sur une surface limitée. Au delà de chaque partie 521, se trouve une partie 523 cylindrique droite présentant à son extrémité un chanfrein.Each roller 52 therefore comprises two curved frustoconical parts 52 1 which have a radius of curvature equal to the radius of the tube of the slide 30 so as to be able to rest on this tube and which are placed on either side of a recessed part , here also cylindrical, curved with a radius of curvature less than that of the tube of the slideway 30. In this way, each roller 52 rolls on the tube of the slideway 30 by bearing on it (by the parts 52 1 ) only on limited area. Beyond each part 52 1 is a straight cylindrical part 52 3 having at its end a chamfer.

    La chape 53 présente une section en forme de deux U dont les âmes 531 se font face, les jambes 532 d'un côté étant confondues alors que les jambes 533 de l'autre côté sont distinctes. Ces dernières portent des supports d'axe 54 (voir également Fig. 2) qui sont solidarisés (par exemple par des rondelles élastiques emmanchées au bout des axes 55) et supportent respectivement les axes 55 autour desquels tournent les galets 52a et 52b.The yoke 53 has a section in the form of two U whose cores 53 1 face each other, the legs 53 2 on one side being combined while the legs 53 3 on the other side are distinct. These latter carry axle supports 54 (see also FIG. 2) which are secured (for example by elastic washers fitted at the end of the axes 55) and respectively support the axes 55 around which the rollers 52a and 52b rotate.

    La chape 53 présente un tourillon 56 qui est monté à pivotement dans un manchon 57 lui-même solidaire de la platine 51. Ainsi, la chape 53 est montée à pivotement sur le panneau 11 à 15 correspondant selon un axe horizontal dans le plan dudit panneau.The yoke 53 has a pin 56 which is pivotally mounted in a sleeve 57 itself secured to plate 51. Thus, the yoke 53 is mounted at pivoting on the corresponding panel 11 to 15 along a horizontal axis in the plane said panel.

    On notera que, dans le mode de réalisation avantageux représenté, l'axe de pivotement de ladite chape 53 se trouve sensiblement dans le plan de symétrie du coulisseau correspondant.It will be noted that, in the advantageous embodiment shown, the axis of pivoting of said yoke 53 is substantially in the plane of symmetry of the corresponding slide.

    Comme on peut le remarquer sur la Fig. 1, le panneau bas 15 présente dans sa partie basse des coulisseaux 26a et 26b spéciaux qui ont pour objet de stopper la chute du vantail 10 lorsque les ressorts 40a et 40b ne sont plus reliés au vantail 10, suite, par exemple, à la coupure accidentée des câbles 44a et 44b. Un tel coulisseau est nommé ci-après stoppe-chute 60 et est représenté en perspective à la Fig. 4.As can be seen in FIG. 1, the bottom panel 15 present in its lower part of the special slides 26a and 26b which are intended to stop the fall leaf 10 when the springs 40a and 40b are no longer connected to leaf 10, continued by example, to the accidental cut of cables 44a and 44b. Such a slide is named below stop-fall 60 and is shown in perspective in FIG. 4.

    Il présente des similitudes avec les coulisseaux 50. En effet, les galets 62 sont identiques aux galets 52 et sont montés de la même manière, notamment avec des supports d'axe 64 et axes identiques aux supports d'axes 54 et axes 55. La chape 63 est sensiblement identique à la chape 53 bien que le tourillon 66, contrairement au tourillon 56, soit décalé par rapport à l'axe de symétrie de la chape 63 (voir Figs. Sa et 5b) et donc du stoppe-chute 60.It has similarities with the slides 50. Indeed, the rollers 62 are identical to the rollers 52 and are mounted in the same way, in particular with axis supports 64 and axes identical to axis supports 54 and axes 55. The clevis 63 is substantially identical to the yoke 53 although the journal 66, unlike the pin 56, either offset from the axis of symmetry of the yoke 63 (see Figs. Sa and 5b) and therefore of the stop-fall 60.

    La platine 61 est arrangée sous la forme d'une équerre pour pouvoir se fixer, d'une part, sur le bord latéral du panneau bas 15 et, d'autre part, sur le bord inférieur du panneau bas 15. Sur la platine 61, un manchon 67 est monté tournant sur et par rapport à la platine 61, contrairement au manchon 57 qui lui était solidaire de la platine 51. Une butée 68 est prévue pour limiter la rotation du manchon 67.The plate 61 is arranged in the form of a square to be able to be fixed, on the one hand, on the lateral edge of the bottom panel 15 and, on the other hand, on the lower edge of the bottom panel 15. On the plate 61, a sleeve 67 is mounted rotating on and by compared to the plate 61, unlike the sleeve 57 which was integral with the plate 51. A stop 68 is provided to limit the rotation of the sleeve 67.

    Le tourillon 66 est emmanché dans le manchon 57 dans lequel il peut pivoter. Sur le manchon 67, sont prévus des moyens 69 pour arrimer le câble 44a, 44b relié au ressort 40a, 40b correspondant. En fonctionnement normal, ce câble 44a, 44b exerce une force qui génère un couple tenant à faire tourner le manchon dans le sens montré par la flèche A sur la Fig. 4. Un moyen de rappel, tel qu'un ressort hélicoïdal (non représenté) tend à faire tourner le manchon 67 dans le sens opposé (voir flèche B).The pin 66 is fitted into the sleeve 57 in which it can pivot. On the sleeve 67, means 69 are provided for securing the cable 44a, 44b connected to the corresponding spring 40a, 40b. In normal operation, this cable 44a, 44b exerts a force which generates a couple holding to turn the sleeve in the direction shown by arrow A in FIG. 4. A return means, such as a helical spring (not shown) tends to rotate the sleeve 67 in the opposite direction (see arrow B).

    Une patte 70 est solidaire du manchon 67 et présente, à son extrémité libre, un trou oblong 70a dans lequel est engagé un téton 71 solidaire de la chape 63. Dans un mode de réalisation particulier, le téton 71 est constitué par l'axe du galet 62 correspondant.A tab 70 is integral with the sleeve 67 and has, at its free end, a oblong hole 70a in which is engaged a stud 71 integral with the yoke 63. In a particular embodiment, the stud 71 is constituted by the axis of the roller 62 corresponding.

    Une plaque 72, renforcée sur sa périphérie par un bourrelet 72a, est montée pivotante sur la chape 63 selon un axe X qui est parallèle à l'axe du tourillon 66. Une charnière 73 est prévue sur la chape 63 de manière à matérialiser l'axe X. Au repos, cette plaque 72 repose sur la chape 63 et elle présente un trou 72b qui reçoit un ergot de centrage 74 solidaire de la chape 63. Comme on le verra par la suite, en action, c'est-à-dire lorsque le stoppe-chute est actif, la plaque 72 forme un angle avec la chape 63.A plate 72, reinforced on its periphery by a bead 72a, is mounted pivoting on the yoke 63 along an axis X which is parallel to the axis of the journal 66. A hinge 73 is provided on the yoke 63 so as to materialize the axis X. At rest, this plate 72 rests on the yoke 63 and it has a hole 72b which receives a lug centering 74 integral with the yoke 63. As will be seen later, in action, that is to say when the fall arrest device is active, the plate 72 forms an angle with the yoke 63.

    La plaque 72 présente également une échancrure 75 en forme de U dont les jambes sont parallèles à l'axe de pivotement X et dont l'âme est en demi-circulaire de rayon légèrement supérieur au rayon extérieur du tube qui constitue la glissière 30. Ainsi, la largeur entre lesdites jambes du U est voisine du diamètre extérieur de la glissière 30.The plate 72 also has a U-shaped notch 75 whose legs are parallel to the pivot axis X and whose core is semi-circular from radius slightly greater than the outside radius of the tube which constitutes the slide 30. Thus, the width between said legs of the U is close to the outside diameter of the slide 30.

    On va maintenant expliquer le fonctionnement d'un stoppe-chute selon la présente invention, et ceci en référence aux Figs. 5a et 5b.We will now explain the operation of a fall-arrest according to the present invention, and this with reference to Figs. 5a and 5b.

    Aux Fig. 5a et 5b, on peut reconnaítre la glissière 30, la chape 63, le tourillon 66, la plaque 72 munie de son échancrure 75, le manchon 67 auquel sont fixés, d'une part, les moyens 69 pour arrimer le câble 44a, 44b et, d'autre part, la patte 70 et son trou oblong 70a ainsi que le téton 71. On voit également l'axe X. On remarquera également les galets 62 qui sont représentés en pointillés par les seules traces de leurs parties 621 de rayon égal à celui de la glissière 30.In Figs. 5a and 5b, we can recognize the slide 30, the yoke 63, the journal 66, the plate 72 provided with its notch 75, the sleeve 67 to which are fixed, on the one hand, the means 69 for securing the cable 44a, 44b and, on the other hand, the tab 70 and its oblong hole 70a as well as the stud 71. We also see the X axis. We will also note the rollers 62 which are shown in dotted lines by the only traces of their parts 62 1 of radius equal to that of slide 30.

    A la Fig. 5a, le câble 44a, 44b est tendu Les galets 62 peuvent circuler librement sur la glissière 30 et l'échancrure 75 de la plaque 72 ne vient pas en contact avec le tube de la glissière 30. La patte 70 est en équilibre et se trouve ainsi sensiblement horizontale. Dans cette position, le téton 71 est sensiblement au centre du trou oblong 70a de la patte 70.In Fig. 5a, the cable 44a, 44b is tensioned The rollers 62 can move freely on the slide 30 and the notch 75 of the plate 72 does not come into contact with the slide tube 30. The tab 70 is in equilibrium and is thus found substantially horizontal. In this position, the stud 71 is substantially in the center of the oblong hole 70a leg 70.

    A la Fig. 5b, le câble 44a, 44b est coupé. Cette situation est donnée à titre d'exemple mais l'homme du métier comprendra que le stoppe-chute ici décrit deviendra actif dans d'autres situations équivalentes à celle-ci.In Fig. 5b, the cable 44a, 44b is cut. This situation is given as example but those skilled in the art will understand that the stop-drop described here will become active in other situations equivalent to this.

    Le ressort (non représenté) dont l'action n'est plus contrebalancée par celle du câble 44a, 44b agit sur l'ensemble constitué du manchon 66, de la patte 70 pour le faire tourner comme cela est représenté par une flèche A à la Fig. 5b. Lorsque le trou oblong 70a arrive en butée sur le téton 71, la chape 63 pivote autour de son axe 66 et la plaque 72 pivote par rapport à son axe X. Elles prennent alors la forme d'un V tout en étant arc-boutées sur ladite glissière 30 correspondante. Les bords de l'échancrure 75 entrent alors en contact avec le tube de la glissière 30. La plaque 72 est alors dans une position de coin et toute action supplémentaire sur le vantail 10 qui tend à le faire descendre entraíne une augmentation de cet effet de coincement.The spring (not shown) whose action is no longer offset by that of the cable 44a, 44b acts on the assembly consisting of the sleeve 66, of the tab 70 for the rotate as shown by an arrow A in FIG. 5b. When the hole oblong 70a comes into abutment on the stud 71, the yoke 63 pivots about its axis 66 and the plate 72 pivots with respect to its axis X. They then take the form of a V all by being braced on said corresponding slide 30. The edges of the notch 75 then come into contact with the tube of the slideway 30. The plate 72 is then in a corner position and any additional action on leaf 10 which tends to do so going down causes an increase in this jamming effect.
