The door has stops (36) for at least one pivot between two panels to hold them in a coplanar orientation. The stop can be integrated into the leaf guides for movement between open and closed conditions.

Description

L'invention concerne un vantail pour porte sectionnelle, destiné à obturer une ouverture d'une construction, et une porte comprenant un tel vantail, telle qu'une porte de garage.The invention relates to a leaf for sectional door, intended to close an opening of a building, and a door comprising such a leaf, such as a garage door.

Le vantail des portes sectionnelles est généralement composé de panneaux s'étendant transversalement sur toute la largeur du vantail, deux panneaux adjacents étant articulés l'un à l'autre.The leaf of the sectional doors is generally composed of panels extending transversely over the entire width of the leaf, two adjacent panels being articulated to one another.

En position fermée, le vantail est sensiblement vertical et obture l'ouverture, et en position ouverte, il est sensiblement horizontal, et par exemple situé sous le plafond, dans la construction.In the closed position, the leaf is substantially vertical and closes the opening, and in the open position, it is substantially horizontal, and for example located under the ceiling, in the construction.

Pour l'ouverture de la porte, le vantail est déplacé verticalement, le panneau supérieur pivotant depuis la position verticale vers la position horizontale, tandis que le panneau suivant reste vertical. Ceci est rendu possible par les articulations entre panneaux successifs. Successivement, les panneaux suivants - depuis la partie supérieure du vantail jusqu'à sa partie inférieure - vont effectuer le même mouvement jusqu'à ce que le vantail soit sensiblement plan et horizontal.For the opening of the door, the leaf is moved vertically, the upper panel pivoting from the vertical position to the horizontal position, while the next panel remains vertical. This is made possible by the joints between successive panels. Successively, the following panels - from the upper part of the leaf to its lower part - will make the same movement until the leaf is substantially flat and horizontal.

Le guidage du vantail entre la position fermée et la position ouverte est assuré par des galets latéraux fixés à chaque articulation entre deux panneaux adjacents par des supports de galets, lesdits galets coopérant avec des rails de guidage latéraux liés à un encadrement fixé à la construction.The guiding of the leaf between the closed position and the open position is provided by lateral rollers fixed to each joint between two adjacent panels by roller supports, said rollers cooperating with lateral guide rails connected to a frame fixed to the construction.

De telles portes nécessitent donc l'emploi de nombreux galets et supports de galets, d'où un coût important. De plus, le temps de montage s'en trouve considérablement augmenté, ce qui n'est pas souhaitable.Such doors therefore require the use of many pebbles and pebble supports, hence a significant cost. In addition, the mounting time is considerably increased, which is not desirable.

Ce problème peut être résolu par l'emploi de panneaux de plus grande hauteur, le vantail comportant alors moins d'articulations, et nécessitant de ce fait un nombre de pièces de guidage moins important.This problem can be solved by the use of panels of greater height, the leaf then having fewer joints, and thus requiring a smaller number of guide pieces.

Cependant, l'utilisation de panneaux de grande hauteur ne permet pas de fabriquer des vantaux dont la hauteur peut être ajustée de façon à convenir à toute la gamme des hauteurs des ouvertures des constructions.However, the use of high panels does not allow to manufacture leaves whose height can be adjusted to suit the entire range of heights of the openings of the constructions.

II serait alors nécessaire d'ajouter au vantail un plus petit panneau afin d'adapter la hauteur dudit vantail à la hauteur de l'ouverture considérée. Un ensemble relativement important de panneaux de différentes hauteurs devrait ainsi être prévu en fonction de la hauteur souhaitée du vantail. Ceci s'avérerait extrêmement coûteux, notamment en outillage et en stockage.It would then be necessary to add to the leaf a smaller panel in order to adapt the height of said leaf to the height of the opening considered. A relatively large set of panels of different heights should thus be provided depending on the desired height of the leaf. This would prove extremely expensive, especially in tools and storage.

L'invention a pour but de résoudre ces problèmes.The object of the invention is to solve these problems.

A cet effet, et selon un premier aspect, l'invention concerne un vantail pour porte sectionnelle, destiné à obturer une ouverture d'une construction et pouvant être guidé entre une position fermée, dans laquelle le vantail est sensiblement vertical, et une position ouverte, dans laquelle le vantail est sensiblement horizontal, ledit vantail comportant une pluralité de panneaux s'étendant transversalement sur toute la largeur dudit vantail, lesdits panneaux comportant des moyens réciproques d'articulation permettant l'articulation mutuelle de deux panneaux adjacents.For this purpose, and according to a first aspect, the invention relates to a door leaf for sectional door, intended to close an opening of a construction and can be guided between a closed position, in which the leaf is substantially vertical, and an open position , wherein the leaf is substantially horizontal, said leaf having a plurality of panels extending transversely across the entire width of said leaf, said panels having reciprocal articulation means for mutual articulation of two adjacent panels.

Selon une définition générale de l'invention, le vantail comporte en outre un système de blocage d'au moins une articulation entre deux panneaux adjacents dans une position où lesdits deux panneaux sont sensiblement coplanaires.According to a general definition of the invention, the leaf further comprises a locking system of at least one joint between two adjacent panels in a position where said two panels are substantially coplanar.

Ainsi, l'invention permet de diminuer considérablement le nombre de pièces de guidage nécessaires (galets et supports de galets) et le temps de montage associé, puisque le nombre d'articulation effectives, nécessitant de telles pièces de guidage, est réduit.Thus, the invention makes it possible to considerably reduce the number of necessary guide pieces (rollers and roll supports) and the associated assembly time, since the effective number of joints, requiring such guide pieces, is reduced.

De plus, il est possible d'utiliser des panneaux de petite taille, associés les uns aux autres, de façon à créer un vantail de la hauteur souhaitée, sans pour autant augmenter le nombre de pièces de guidage.In addition, it is possible to use small panels, associated with each other, so as to create a leaf of the desired height, without increasing the number of guide pieces.

Grâce à l'invention, un nombre restreint de panneaux de tailles différentes suffit pour couvrir toute la gamme de hauteurs souhaitées.Thanks to the invention, a limited number of panels of different sizes is sufficient to cover the entire range of desired heights.

De façon à obtenir une porte sectionnelle, le vantail présente au moins une articulation non bloquée entre deux panneaux adjacents.In order to obtain a sectional door, the leaf has at least one non-locked joint between two adjacent panels.

Le système de blocage peut intégrer des moyens de guidage du vantail entre la position fermée et la position ouverte.The locking system can incorporate leaf guiding means between the closed position and the open position.

En outre, le système de blocage peut être placé à l'extérieur du vantail et solidariser au moins deux panneaux adjacents au voisinage de leurs deux bords latéraux. Le système de blocage est par exemple agencé pour renforcer les panneaux qu'il solidarise.In addition, the locking system can be placed outside the leaf and secure at least two adjacent panels in the vicinity of their two side edges. The locking system is for example arranged to reinforce the panels that it solidifies.

Ainsi, le système de blocage peut former moyen de renfort du vantail, ce dernier pouvant donc être sensiblement dépourvu de moyens de renfort intérieurs, ce qui simplifie le montage du vantail et diminue son coût.Thus, the locking system can form the leaf reinforcement means, the latter can therefore be substantially devoid of internal reinforcing means, which simplifies the mounting of the leaf and reduces its cost.

Par « à l'intérieur du vantail », on entend dans la structure même du vantail, notamment si ce dernier est creux. L'expression « à l'extérieur du vantail » signifie que le système de blocage est une pièce rapportée venant se positionner sur le vantail.By "inside the leaf" is meant in the same structure of the leaf, especially if it is hollow. The expression "outside the leaf" means that the locking system is an insert that is positioned on the leaf.

L'invention permet de munir le vantail d'un système de blocage pouvant en outre avoir une fonction de support d'autres pièces et une fonction de renfort, ceci évitant ainsi un montage fastidieux ou nécessitant la fixation de nombreuses pièces.The invention makes it possible to provide the leaf with a locking system that can also have a function of supporting other parts and a reinforcing function, thus avoiding a fastidious assembly or requiring the attachment of many parts.

Ceci est particulièrement avantageux dans le cas d'un vantail dont les panneaux sont réalisés en matière plastique. En effet, la fixation de pièces directement dans la matière plastique s'avère peu satisfaisante, et le vantail dépourvu de renforts intérieurs ne présenterait pas la résistance requise.This is particularly advantageous in the case of a leaf whose panels are made of plastic. Indeed, the attachment of parts directly in the plastic is unsatisfactory, and the leaf lacking internal reinforcements do not have the required strength.

Selon une réalisation possible, le système de blocage comprend au moins une barre présentant une section en U, ladite barre étant placée longitudinalement à un bord latéral du vantail de sorte à entourer une partie extrême latérale d'un ensemble d'au moins deux panneaux adjacents au voisinage de leur articulation, le fond du U couvrant la tranche desdits panneaux, une première branche du U étant adjacente à un premier côté des panneaux et une deuxième branche du U étant adjacente à un deuxième côté des panneaux, la hauteur de ladite barre étant inférieure à la hauteur du vantail.According to one possible embodiment, the locking system comprises at least one bar having a U-shaped section, said bar being placed longitudinally at a lateral edge of the leaf so as to surround a lateral end portion of a set of at least two adjacent panels in the vicinity of their articulation, the bottom of the U covering the edge of said panels, a first leg of the U being adjacent to a first side of the panels and a second leg of the U being adjacent to a second side of the panels, the height of said bar being less than the height of the leaf.

Par exemple, le système de blocage comprend trois couples de barres, les deux barres d'un même couple entourant les parties extrêmes latérales opposées d'au moins deux panneaux adjacents, de sorte que le vantail comporte trois panneaux effectifs et deux articulations effectives.For example, the locking system comprises three pairs of bars, the two bars of the same pair surrounding the opposite lateral end portions of at least two adjacent panels, so that the leaf comprises three effective panels and two effective joints.

Selon d'autres caractéristiques, les panneaux sont creux et comprennent une paroi intérieure et une paroi extérieure, les moyens de guidage étant fixés à un panneau par l'intermédiaire du système de blocage, de telle de sorte qu'une paroi dudit panneau soit prise en sandwich entre une partie desdits moyens de guidage et une partie dudit système de blocage.According to other features, the panels are hollow and comprise an inner wall and an outer wall, the guide means being fixed to a panel by means of the locking system, such that a wall of said panel is taken sandwiched between a portion of said guide means and a portion of said locking system.

Par exemple, chaque panneau du vantail est réalisé en un matériau appartenant au groupe formé par les matières plastiques opaques, les matières plastiques translucides, le bois et le métal. Les panneaux peuvent être réalisés en des matériaux différents ou des couleurs différentes afin d'obtenir des effets esthétiques variés.For example, each panel of the leaf is made of a material belonging to the group formed by opaque plastics, translucent plastics, wood and metal. The panels can be made of different materials or different colors in order to obtain varied aesthetic effects.

Selon l'invention, chaque panneau du vantail est réalisé à partir d'un profilé en matière plastique, ledit profilé étant choisi parmi un ensemble constitué de deux profilés de hauteurs différentes.According to the invention, each panel of the leaf is made from a plastic profile, said profile being selected from an assembly consisting of two profiles of different heights.

Ainsi, seuls deux profilés sont nécessaires pour couvrir sensiblement toute le gamme des hauteurs de vantail. Il s'ensuit un gain considérable en termes de coûts de fabrication et de stockage.Thus, only two profiles are necessary to cover substantially the entire range of leaf heights. This results in a considerable gain in terms of manufacturing and storage costs.

Chaque profilé peut être monobloc et comprendre une partie médiane, sensiblement parallélépipédique, une première partie extrême présentant une gorge longitudinale, et une deuxième partie extrême comportant un tube longitudinal apte à coopérer avec la gorge d'un profilé adjacent de sorte à permettre l'articulation mutuelle de deux panneaux adjacents.Each profile may be one-piece and comprise a median, substantially parallelepipedal portion, a first end portion having a longitudinal groove, and a second end portion comprising a longitudinal tube adapted to cooperate with the groove of an adjacent profile so as to allow articulation of two adjacent panels.

Enfin, selon un deuxième aspect, l'invention concerne une porte sectionnelle comprenant deux rails latéraux de guidage destinés à être fixés à la structure d'une construction au niveau d'une ouverture de ladite construction, ainsi qu'un vantail tel que précédemment décrit, le vantail pouvant être guidé par les rails entre une position fermée, dans laquelle le vantail obture l'ouverture, et une position ouverte.Finally, according to a second aspect, the invention relates to a sectional door comprising two lateral guide rails intended to be fixed to the structure of a construction at an opening of said construction, as well as a leaf as previously described. , the leaf being guided by the rails between a closed position, in which the leaf closes the opening, and an open position.

On se réfère tout d'abord à la figure 1 qui représente une porte 1 sectionnelle, telle qu'une porte de garage.Referring firstly to Figure 1 which shows a sectional door 1, such as a garage door.

On définit une première direction D1, sensiblement verticale, par rapport à laquelle seront employés les termes « longitudinal », « hauteur », « inférieur », « supérieur ».We define a first direction D1, substantially vertical, with respect to which will be used the terms "longitudinal", "height", "lower", "higher".

La porte 1 comprend un encadrement 2, destiné à être fixé à la structure d'une construction au niveau d'une ouverture de ladite construction. L'encadrement 2 comprend lui-même deux montants verticaux 3, 4 ainsi qu'une traverse supérieure 5 sensiblement horizontale.The door 1 comprises a frame 2, intended to be fixed to the structure of a construction at an opening of said construction. The frame 2 itself comprises two vertical uprights 3, 4 and a substantially horizontal upper cross member 5.

On définit une deuxième direction D2, sensiblement parallèle à la traverse 5, par rapport à laquelle seront employés les termes « latéral », « transversal », « largeur », ainsi qu'une troisième direction D3 telle que (D1, D2, D3) forme un repère orthogonal.We define a second direction D2, substantially parallel to the crossbar 5, with respect to which will be used the terms "lateral", "transverse", "width", and a third direction D3 such that (D1, D2, D3) forms an orthogonal reference.

La porte 1 est également munie de deux rails latéraux de guidage 10. Chaque rail de guidage 10 forme un angle et comprend une première partie fixée sur un montant 3, 4 et une deuxième partie 7, 8, s'étendant selon la direction D3 depuis la traverse supérieure 5.The door 1 is also provided with two lateral guiding rails 10. Each guide rail 10 forms an angle and comprises a first part fixed on an upright 3, 4 and a second part 7, 8, extending in the direction D3 from the top rail 5.

La porte 1 comporte de plus une traverse arrière 9, parallèle à la traverse supérieure 5, connectant les extrémités des deuxièmes parties 7, 8 des rails 10 non liées aux montants 3, 4. Les deuxièmes parties 7, 8 des rails 10 et la traverse arrière 9 sont destinées à être fixés au plafond à l'intérieur I de la construction.The door 1 further comprises a rear crossmember 9, parallel to the upper crossmember 5, connecting the ends of the second parts 7, 8 of the rails 10 not connected to the uprights 3, 4. The second parts 7, 8 of the rails 10 and the crossbar Rear 9 are intended to be attached to the ceiling inside I of the building.

La porte 1 comprend en outre un vantail 11 destiné à obturer l'ouverture de la construction.The door 1 further comprises a leaf 11 intended to close the opening of the construction.

Le vantail 11 comporte des moyens de guidage (supports de galets 12 et galets 13) coopérant avec les rails latéraux 10, de sorte que le vantail 11 peut être déplacé entre une position fermée, dans laquelle le vantail est sensiblement vertical et obture l'ouverture, et une position ouverte, dans laquelle le vantail est sensiblement horizontal, et situé sous le plafond de la construction, à l'intérieur 1 de celle-ci.The leaf 11 comprises guide means (supports of rollers 12 and rollers 13) cooperating with the lateral rails 10, so that the leaf 11 can be moved between a closed position, in which the leaf is substantially vertical and closes the opening , and an open position, in which the leaf is substantially horizontal, and located under the ceiling of the building, inside 1 thereof.

L'équilibrage de la porte 1 est réalisé par un système d'arbre et de ressorts non représenté.The balancing of the door 1 is achieved by a shaft and spring system not shown.

Le vantail 11 comporte une pluralité de panneaux 14 s'étendant transversalement sur toute la largeur du vantail 11. Comme il sera décrit plus loin, les panneaux 14 comprennent des moyens réciproques d'articulation pour permettre le pivotement d'un panneau par rapport au panneau adjacent lors de l'ouverture ou de la fermeture de la porte 1.The leaf 11 comprises a plurality of panels 14 extending transversely over the entire width of the leaf 11. As will be described later, the panels 14 comprise reciprocating means of articulation to allow the pivoting of a panel relative to the panel adjacent when opening or closing the door 1.

Chaque panneau 14 est réalisé à partir d'un profilé monobloc creux en matière plastique, par exemple en PVC. Deux profilés 15, 16 seulement sont utilisés pour la réalisation de l'ensemble des panneaux 14 du vantail 11. Le premier profilé 15, représenté en section sur la figure 2, présente une hauteur plus importante que le deuxième profilé 16, représenté en section sur la figure 3.Each panel 14 is made from a hollow monobloc profile made of plastic, for example PVC. Only two profiles 15, 16 only are used for producing all the panels 14 of the leaf 11. The first section 15, shown in section in Figure 2, has a greater height than the second section 16, shown in section on Figure 3.

Chaque profilé 15, 16 comprend une paroi intérieure 17 sensiblement plane, destinée à être placée à l'intérieur I de la construction, et une paroi extérieure 18 courbe, généralement parallèle à la paroi intérieure 17, destinée à être placée à l'extérieur E de la construction. La paroi extérieure 18 du premier profilé 15 est en creux, tandis que la paroi extérieure 18 du deuxième profilé 16 est bombée. Chaque profilé 15, 16 comprend ainsi une partie médiane 19 sensiblement parallélépipédique, dont une face est en creux ou bombée.Each section 15, 16 comprises a substantially flat inner wall 17, intended to be placed inside I of the construction, and an outer wall 18 curved, generally parallel to the inner wall 17, to be placed outside E construction. The outer wall 18 of the first section 15 is hollow, while the outer wall 18 of the second section 16 is curved. Each section 15, 16 thus comprises a substantially parallelepipedal median portion 19, one face of which is hollow or curved.

Une ou plusieurs parois internes 20 de renfort sont prévues perpendiculairement aux parois intérieure 17 et extérieure 18.One or more internal reinforcing walls 20 are provided perpendicularly to the inner 17 and outer 18 walls.

Les profilés 15, 16 comprennent en outre une première partie extrême 21, destinée à former la partie supérieure d'un panneau 14. La première partie extrême 21 comporte une gorge 22 longitudinale, ouverte à l'opposé de la partie médiane 19, et présentant une section en arc de cercle couvrant un angle d'environ 180 à 230°.The profiles 15, 16 further comprise a first end portion 21, intended to form the upper part of a panel 14. The first end portion 21 comprises a longitudinal groove 22, open opposite the middle portion 19, and having an arcuate section covering an angle of about 180 to 230 °.

Les extrémités des parois de la gorge 22 sont décalées en hauteur l'une par rapport à l'autre, l'extrémité située vers la paroi extérieure 18 du profilé 15, 16 étant plus haute que l'extrémité située vers la paroi intérieure 17 du profilé 15, 16. Ainsi, d'une part, la paroi de la gorge 22 située vers la paroi extérieure 18 du profilé 15, 16 forme un bec en saillie, et, d'autre part, l'ouverture de la gorge 22 est orientée légèrement vers la paroi intérieure 17.The ends of the walls of the groove 22 are offset in height relative to each other, the end located towards the outer wall 18 of the profile 15, 16 being higher than the end located towards the inner wall 17 of the profile 15, 16. Thus, on the one hand, the wall of the groove 22 located towards the outer wall 18 of the profile 15, 16 forms a projecting spout, and, on the other hand, the opening of the groove 22 is slightly oriented towards the inner wall 17.

En outre, les extrémités des parois de la gorge 22 forment chacune un repli 23, 24 vers l'intérieur de ladite gorge 22.In addition, the ends of the walls of the groove 22 each form a fold 23, 24 towards the inside of said groove 22.

Au voisinage de la gorge 22, la paroi extérieure 18 du profilé 15, 16 forme un renfoncement 25.In the vicinity of the groove 22, the outer wall 18 of the profile 15, 16 forms a recess 25.

Par ailleurs, au niveau de la première partie extrême 21, la paroi intérieure 17 comprend une première portion, s'étendant dans la continuité de la paroi intérieure 17 de la partie médiane 19 et formant une saillie 26, et une deuxième portion 27, s'étendant sensiblement parallèlement à la direction de la paroi intérieure 17 de la partie médiane 19, en retrait vers la paroi extérieure 18.Furthermore, at the first end portion 21, the inner wall 17 comprises a first portion, extending in the continuity of the inner wall 17 of the middle portion 19 and forming a projection 26, and a second portion 27, s extending substantially parallel to the direction of the inner wall 17 of the middle portion 19, recessed towards the outer wall 18.

Entre la saillie 26 et la deuxième portion en retrait 27 est ainsi formée une rainure 28, ouverte vers le haut, et munie de dents intérieures 29 agencées sur la saillie 26.Between the projection 26 and the second recessed portion 27 is thus formed a groove 28, open upwards, and provided with inner teeth 29 arranged on the projection 26.

Les rôles des replis 23, 24, du renfoncement 25, de la rainure 28 et des dents 29 seront expliqués plus loin.The roles of the recesses 23, 24, the recess 25, the groove 28 and the teeth 29 will be explained later.

Enfin, les profilés 15, 16 comprennent une deuxième partie extrême 30, destinée à former la partie inférieure d'un panneau 14.Finally, the profiles 15, 16 comprise a second end portion 30 intended to form the lower part of a panel 14.

La deuxième partie extrême 30 comporte tout d'abord une portion sensiblement parallélépipédique 31 s'étendant depuis la partie médiane 19 et en prolongement de celle-ci. La distance entre les parois intérieure 17 et extérieure 18 du profilé 15, 16 au niveau de la portion parallélépipédique 31 est inférieure à celle existant au niveau de la partie médiane 19, par exemple de l'ordre de la moitié ou des deux tiers.The second end portion 30 firstly comprises a substantially parallelepipedal portion 31 extending from the middle portion 19 and an extension thereof. The distance between the inner 17 and outer 18 walls of the profile 15, 16 at the parallelepipedal portion 31 is less than that existing at the middle portion 19, for example of the order of half or two thirds.

En prolongement de la portion parallélépipédique 31, la deuxième partie extrême 30 comporte un tube longitudinal 32 dont le centre est situé sensiblement en prolongement de la paroi intérieure 17 de la portion parallélépipédique 31, et dont le diamètre est voisin de la moitié de la distance entre les parois intérieure 17 et extérieure 18 du profilé 15, 16 au niveau de la partie médiane 19. Le tube 32 présente des saillies extérieures longitudinales 33, sensiblement diamétralement opposées, et s'étendant sensiblement parallèlement aux parois internes 20 de renfort au voisinage du centre du tube.In extension of the parallelepipedal portion 31, the second end portion 30 comprises a longitudinal tube 32 whose center is located substantially in extension of the inner wall 17 of the parallelepipedal portion 31, and whose diameter is close to half the distance between the inner and outer walls 17 of the profile 15, 16 at the middle portion 19. The tube 32 has longitudinal outer projections 33, substantially diametrically opposed, and extending substantially parallel to the inner reinforcing walls 20 in the vicinity of the center. of the tube.

Le tube 32 du premier profilé 15 comprend des renforts intérieurs 34, tandis que le tube 32 du deuxième profilé 16 en est dépourvu, notamment pour économiser de la matière.The tube 32 of the first profile 15 comprises internal reinforcements 34, while the tube 32 of the second profile 16 is devoid of it, in particular to save material.

Enfin, la paroi extérieure 18 du profilé 15, 16 est prolongée au-delà de la portion parallélépipédique 31, sensiblement jusqu'en regard des saillies 33, de sorte qu'une gorge 35 est formée entre la portion parallélépipédique 31, la paroi extérieure 18 et le tube 32.Finally, the outer wall 18 of the profile 15, 16 is extended beyond the parallelepipedal portion 31, substantially facing the projections 33, so that a groove 35 is formed between the parallelepipedal portion 31, the outer wall 18 and the tube 32.

Comme dans le cas de la première partie extrême 21, une rainure 28 existe entre une saillie 26 située en prolongement de la paroi intérieure 17 du profilé 15, 16 et une portion en retrait 27 de ladite paroi intérieure 17. La rainure 28 est située sur la partie médiane 19, au voisinage de la portion parallélépipédique 31 de la deuxième partie extrême 30. La rainure 28 est ouverte vers le bas et comprend des dents 29 intérieures agencées sur la saillie 26.As in the case of the first end portion 21, a groove 28 exists between a projection 26 located in extension of the inner wall 17 of the profile 15, 16 and a recessed portion 27 of said inner wall 17. The groove 28 is located on the middle part 19, in the vicinity of the parallelepipedal portion 31 of the second end portion 30. The groove 28 is open downward and includes inner teeth 29 arranged on the projection 26.

Les parties extrêmes 21, 30 des profilés 15, 16 peuvent également comporter des parois intérieures de renfort.The end portions 21, 30 of the profiles 15, 16 may also comprise internal reinforcing walls.

Les parois des profilés 15, 16 présentent une épaisseur de l'ordre de 0,8 à 1,5 mm. La hauteur du premier profilé 15 est de l'ordre de 250 à 350 mm, et la hauteur du deuxième profilé 16 de l'ordre de 100 à 200 mm. L'épaisseur totale des profilés 15, 16 - entre la paroi intérieure 17 et la paroi extérieure 18 - est voisine de 40 mm.The walls of the profiles 15, 16 have a thickness of the order of 0.8 to 1.5 mm. The height of the first section 15 is of the order of 250 to 350 mm, and the height of the second section 16 of the order of 100 to 200 mm. The total thickness of the profiles 15, 16 - between the inner wall 17 and the outer wall 18 - is close to 40 mm.

Chaque panneau 14 est réalisé par découpe de l'un des profilés 15, 16 à la dimension souhaitée.Each panel 14 is made by cutting one of the profiles 15, 16 to the desired size.

On décrit à présent la coopération de panneaux 14 adjacents, en référence à la figure 4, sur laquelle est représenté un panneau médian 14a, réalisé à partir du deuxième profilé 16, associé à chacune de ses parties extrêmes supérieure et inférieure à un panneau supérieur 14b et inférieur 14c tous deux réalisés à partir du premier profilé 15.The cooperation of adjacent panels 14 is now described, with reference to FIG. 4, on which is represented a median panel 14a, made from the second section 16, associated with each of its upper and lower end portions with an upper panel 14b. and lower 14c both made from the first profile 15.

Le tube 32 d'un profilé 15, 16 est apte à coopérer avec la gorge 22 d'un profilé 15, 16 adjacent, de sorte à permettre l'articulation mutuelle de deux panneaux 14 adjacents. Ainsi, le tube 32 est logé dans la gorge 22, tandis que la paroi de la gorge 22 située vers la paroi extérieure 18 du profilé 15, 16 est logée dans la gorge 35.The tube 32 of a profile 15, 16 is adapted to cooperate with the groove 22 of a profile 15, 16 adjacent, so as to allow the mutual articulation of two adjacent panels 14. Thus, the tube 32 is housed in the groove 22, while the wall of the groove 22 located towards the outer wall 18 of the profile 15, 16 is housed in the groove 35.

Les parties extrêmes 21, 30 de chaque profilé 15, 16 présentent des moyens réciproques permettant de limiter l'amplitude du mouvement d'articulation mutuelle de deux panneaux adjacents, comme illustré sur la figure 4.The end portions 21, 30 of each profile 15, 16 have reciprocal means for limiting the amplitude of the mutual articulation movement of two adjacent panels, as illustrated in FIG. 4.

D'une part, le mouvement d'articulation du panneau inférieur 14c est limité par rapport au panneau médian 14a dans le sens inverse des aiguilles d'une montre par la coopération du repli 24 avec une saillie 33 et de la paroi extérieure 18 avec le renfoncement 25.On the one hand, the hinge movement of the lower panel 14c is limited compared to the medial panel 14a in the opposite direction of clockwise by the cooperation of the fold 24 with a projection 33 and the outer wall 18 with the recess 25.

D'autre part, le mouvement d'articulation du panneau supérieur 14b est limité par rapport au panneau médian 14a dans le sens des aiguilles d'une montre par la coopération du repli 23 avec l'autre des saillies 33.On the other hand, the articulation movement of the upper panel 14b is limited with respect to the medial panel 14a in the clockwise direction by the cooperation of the fold 23 with the other of the projections 33.

II est à noter que les profilés 15, 16 sont conçus pour empêcher qu'un utilisateur se pince les doigts lors du pivotement des panneaux 14 les uns par rapport aux autres.It should be noted that the profiles 15, 16 are designed to prevent a user pinches his fingers when pivoting the panels 14 relative to each other.

Plusieurs panneaux 14 sont associés de cette façon afin de former le vantail 11. Le nombre de panneaux 14 réalisés à partir du premier profilé 15 et le nombre de panneaux 14 réalisés à partir du deuxième profilé 16 sont déterminés en fonction de la hauteur totale souhaitée du vantail 11.Several panels 14 are associated in this way to form the leaf 11. The number of panels 14 made from the first profile 15 and the number of panels 14 made from the second profile 16 are determined according to the desired total height of the leaf 11.

L'un des profilés, par exemple le deuxième profilé 16, peut être réalisé en matière plastique translucide, de façon à permettre une entrée de lumière dans la construction lorsque le vantail est en position fermée. D'autres matériaux (aluminium, bois, etc.) ou d'autres couleurs peuvent être utilisés pour obtenir des effets esthétiques variés.One of the profiles, for example the second profile 16, may be made of translucent plastic, so as to allow light entry into the construction when the leaf is in the closed position. Other materials (aluminum, wood, etc.) or other colors can be used to achieve various aesthetic effects.

De façon à éviter un trop grand nombre d'articulations du vantail 11, l'invention prévoit un système de blocage, qui est maintenant décrit en référence aux figures 5 à 15.In order to avoid too many joints of the leaf 11, the invention provides a locking system, which is now described with reference to Figures 5 to 15.

Le système de blocage comprend un ensemble de barres 36 destinées à être fixées sur les panneaux 14 et à solidariser au moins deux panneaux 14 adjacents au voisinage de leurs bords latéraux.The locking system comprises a set of bars 36 intended to be fixed on the panels 14 and to secure at least two panels 14 adjacent to the vicinity of their side edges.

Une barre 36 présente une section en U comprenant un fond 37, une première branche 38 et une deuxième branche 39 s'étendant depuis le fond 37 sur une distance moindre que la distance sur laquelle s'étend la première branche 38, par exemple la moitié.A bar 36 has a U-shaped section comprising a bottom 37, a first leg 38 and a second leg 39 extending from the bottom 37 for a distance less than the distance over which the first leg 38 extends, for example half .

La barre 36 comprend au voisinage de chacune de ses extrémités une fente 40 longitudinale pratiquée dans le fond 37 du U, vers la première branche 38, ladite fente 40 étant destinée à recevoir une partie des moyens de guidage du vantail 11 entre la position fermée et la position ouverte.The bar 36 comprises in the vicinity of each of its ends a longitudinal slot 40 formed in the bottom 37 of the U, to the first leg 38, said slot 40 being intended to receive a portion of the guide means of the leaf 11 between the closed position and the open position.

La barre 36 est placée longitudinalement à un bord latéral du vantail 11, de sorte à entourer une partie extrême latérale d'un ensemble d'au moins deux panneaux 14 adjacents au voisinage de leur articulation. Le fond 37 du U couvre la tranche des panneaux 14, la première branche 38 du U est adjacente à la paroi intérieure 17 des panneaux 14, et la deuxième branche 39 du U est adjacente à la paroi extérieure 18 des panneaux 14. L'articulation entre les panneaux 14 est ainsi bloquée, dans une position où lesdits panneaux 14 sont sensiblement coplanaires.The bar 36 is placed longitudinally at a lateral edge of the leaf 11, so as to surround a lateral end portion of an assembly of at least two panels 14 adjacent to the vicinity of their articulation. The bottom 37 of the U covers the edge of the panels 14, the first leg 38 of the U is adjacent to the inner wall 17 of the panels 14, and the second leg 39 of the U is adjacent to the outer wall 18 of the panels 14. The articulation between the panels 14 is thus blocked, in a position where said panels 14 are substantially coplanar.

La hauteur de la barre 36 est inférieure à la hauteur du vantail 11, et sensiblement égale à la hauteur de l'ensemble de panneaux 14 qu'elle entoure.The height of the bar 36 is less than the height of the leaf 11, and substantially equal to the height of the set of panels 14 that it surrounds.

La partie extrême supérieure et la partie extrême inférieure de la barre 36 sont agencées de telle sorte que les parties extrêmes adjacentes de deux barres 36 adjacentes puissent coopérer au voisinage d'une articulation entre deux panneaux 14 et autoriser l'articulation mutuelle desdits panneaux 14.The upper end portion and the lower end portion of the bar 36 are arranged such that the adjacent end portions of two adjacent bars 36 can cooperate in the vicinity of a joint between two panels 14 and allow the mutual articulation of said panels 14.

A cet effet, comme représenté sur les figures 5, 7 et 15, la partie extrême supérieure de la barre 36 présente une échancrure 41, et la partie extrême inférieure présente une proéminence 42 arrondie apte à coopérer avec l'échancrure 41 d'une barre 36 adjacente.For this purpose, as shown in Figures 5, 7 and 15, the upper end portion of the bar 36 has a notch 41, and the lower end portion has a rounded protrusion 42 capable of cooperating with the notch 41 of a bar 36 adjacent.

La barre 36 est placée sur l'ensemble de panneaux 14 qu'elle entoure de sorte que la gorge 22 du panneau 14 supérieur de l'ensemble saille au-dessus de l'échancrure 41 et que le tube 32 du panneau 14 inférieur de l'ensemble soit en regard de la proéminence 42 arrondie. Le pivotement d'un panneau 14 par rapport à un panneau 14 adjacent n'est ainsi pas entravé par les barres 36 adjacentes.The bar 36 is placed on the set of panels 14 which it surrounds so that the groove 22 of the upper panel 14 of the assembly protrudes above the notch 41 and that the tube 32 of the lower panel 14 of the together be next to the rounded prominence 42. The pivoting of a panel 14 with respect to an adjacent panel 14 is thus not impeded by the adjacent bars 36.

Selon le mode de réalisation représenté, le système de blocage comprend trois couples de barres 36, les deux barres 36 d'un même couple entourant les parties extrêmes latérales opposées d'au moins deux panneaux 14 adjacents, de sorte que le vantail 11 comporte trois panneaux 14 effectifs et deux articulations effectives (voir figure 14). Les barres 36 solidarisent ici deux ou trois panneaux 14.According to the embodiment shown, the locking system comprises three pairs of bars 36, the two bars 36 of the same pair surrounding the opposite end portions of at least two adjacent panels 14, so that the leaf 11 comprises three effective panels 14 and two effective joints (see Figure 14). The bars 36 solidarisent here two or three panels 14.

Le système de blocage intègre également des moyens de guidage du vantail 11 entre la position fermée et la position ouverte.The locking system also incorporates means for guiding the leaf 11 between the closed position and the open position.

A cet effet, les supports de galets 12 présentent la forme d'un L comportant :

  • une première branche 43 apte à être introduite à l'intérieur d'un panneau 14 par la fente de la barre 36 de sorte que la paroi intérieure 17 du panneau 14 soit prise en sandwich entre la première branche 43 du support de galet 12 et la première branche 38 de la barre 36 en U ;
  • et une deuxième branche 44, saillant vers l'extérieur du vantail 11, apte à porter un galet 13 pour le guidage du vantail 11 entre la position fermée et la position ouverte.
For this purpose, the roller supports 12 have the shape of an L comprising:
  • a first branch 43 adapted to be introduced inside a panel 14 by the slit of the bar 36 so that the inner wall 17 of the panel 14 is sandwiched between the first branch 43 of the roller support 12 and the first branch 38 of the U-shaped bar 36;
  • and a second branch 44 protruding outwards from the leaf 11, capable of carrying a roller 13 for guiding the leaf 11 between the closed position and the open position.

Des moyens de fixation, tels que des vis 45, permettent de solidariser la paroi intérieure 17 du panneau 14, le support de galet 12 et la barre 36 (figure 11). Un vissage des supports de galets 12 directement dans le panneau 14 ne serait pas satisfaisant, dans la mesure où le panneau 14 est réalisé à partir d'un profilé 15,16 creux en matière plastique.Fixing means, such as screws 45, make it possible to secure the inner wall 17 of the panel 14, the roller support 12 and the bar 36 (FIG. 11). Screwing the roller supports 12 directly into the panel 14 would not be satisfactory, since the panel 14 is made from a hollow section 15,16 of plastics material.

D'autres supports de galets 12, par exemple ceux destinés à être placés à l'extrémité inférieure du vantail 11, comportent en outre une troisième branche 46, sensiblement parallèle à la première branche 43, ladite troisième branche 46 étant destinée à être placée à l'extérieur du panneau 14, sensiblement en contact avec la première branche 38 de la barre 36 en U (voir figures 8 et 12).Other roller supports 12, for example those intended to be placed at the lower end of the leaf 11, further comprise a third leg 46, substantially parallel to the first leg 43, said third leg 46 being intended to be placed at the outside of the panel 14, substantially in contact with the first leg 38 of the U-shaped bar 36 (see FIGS. 8 and 12).

Par ailleurs, le vantail 11 peut également comprendre un profilé inférieur 47 apte à coopérer avec la partie extrême inférieure du vantail 11, et destiné à recevoir un joint 48 (figures 9, 13).Furthermore, the leaf 11 may also include a lower section 47 adapted to cooperate with the lower end portion of the leaf 11, and for receiving a seal 48 (Figures 9, 13).

Le profilé inférieur 48 comporte un logement longitudinal 49 destiné à recevoir le tube 32 du panneau 14 inférieur du vantail 11 et à coopérer avec lui. En outre, le profilé inférieur 48 comporte une paroi en saillie 50 s'étendant depuis le logement 49 vers le panneau 14 inférieur et destinée à être engagée dans la rainure 28 de la deuxième partie extrême 30 dudit panneau 14, la fixation étant assurée par les dents 29. Enfin, le profilé inférieur 48 comporte une gorge 51, ouverte vers le bas, destinée à recevoir le joint 48.The lower section 48 comprises a longitudinal recess 49 intended to receive the tube 32 of the lower panel 14 of the leaf 11 and to cooperate with it. In addition, the lower profile 48 has a projecting wall 50 extending from the housing 49 to the lower panel 14 and intended to be engaged in the groove 28 of the second end portion 30 of said panel 14, the fixing being ensured by the Finally, the lower profile 48 has a groove 51, open downwards, intended to receive the seal 48.

Un profilé haut (non représenté) peut également être prévu pour coopérer avec la gorge 22 du panneau 14 supérieur du vantail 11. De plus, la porte 1 peut être munie d'un serrure destinée à permettre le verrouillage du vantail 11 en position fermée.A high profile (not shown) may also be provided to cooperate with the groove 22 of the upper panel 14 of the leaf 11. In addition, the door 1 may be provided with a lock for allowing the locking of the leaf 11 in the closed position.

Sur la figure 14 est représenté une porte 1 dont le vantail 11 est dans une position intermédiaire entre la position fermée et la position ouverte.In Figure 14 is shown a door 1 whose leaf 11 is in an intermediate position between the closed position and the open position.

Les deux panneaux 14 inférieurs sont solidarisés par un premier couple de barres 36, les deux panneaux 14 médians sont solidarisés par un deuxième couple de barres 36, et les trois panneaux 14 supérieurs - deux panneaux 14 réalisés à partir du premier profilé 15 et un panneau réalisé à partir du deuxième profilé 16 - sont solidarisés par un troisième couple de barres 36.The two lower panels 14 are secured by a first pair of bars 36, the two median panels 14 are secured by a second pair of bars 36, and the three upper panels 14 - two panels 14 made from the first section 15 and a panel made from the second profile 16 - are secured by a third pair of bars 36.

Les supports de galets 12 sont intégrés aux barres 36, et sont associés aux galets 13 qui coopèrent avec les rails 10 pour le déplacement du vantail 11 entre la position fermée et la position ouverte.The roller supports 12 are integrated in the bars 36, and are associated with the rollers 13 which cooperate with the rails 10 for the movement of the leaf 11 between the closed position and the open position.

Le vantail 11 comporte ainsi trois panneaux effectifs et deux articulations effectives. L'encombrement du vantail 11 lors de son déplacement est supérieur à celui d'une porte sectionnelle connue, mais le gain en coût et en temps de montage est très important.The leaf 11 thus comprises three effective panels and two effective joints. The size of the leaf 11 during its movement is greater than that of a known sectional door, but the cost and time gain is very important.

Bien entendu, l'invention n'est pas limitée à cette réalisation particulière. On pourrait notamment bloquer certaines des articulations du vantail 11 de façon différente, ou à des endroits différents, par exemple par des vis placées au niveau des articulations.Of course, the invention is not limited to this particular embodiment. One could in particular block some of the joints of the leaf 11 differently, or at different locations, for example by screws placed at the joints.
