Abstract

1. Folding door assembly of the kind comprising two panels hinged one to the other, these being a first panel (1) of small width hinged to an upright (4) of the frame of the door and a second panel (2) of greater width hinged to the first panel, said second panel assuming a position crosswise to the frame with one part on either side thereof when the door is in the open position, characterised in that the door is used in conjunction with a conventional rebated frame with no floor-mounted element and in that the hinged means of the first panel (1) are installed in a fixed position at a distance sufficiently far away from the upright to allow the said first panel (1) to open in a direction opposite from that in which the rebate faces such that, in the closed position, the edge of the second panel butts into the rebate, thus allowing a conventional lock to be used and in that the assembly also comprises a channel (15) shaped to contain a slot, said channel being intended to be positioned in the lintel rebate to enable a peg (20) secured to the second panel (2) to slide in the slot.

Description

La présente invention a pour objet une porte pliante constituée d'au moins deux panneaux articulés l'un sur l'autre, permettant de dégager une ouverture large, tout en occupant en position ouverte un débatte­ment réduit. Les figures 1 et 2 représentent en coupe horizontale schématique le fonctionnement d'une telle porte. Elle est constituée de deux panneaux, un premier panneau 1 et un deuxième panneau 2 réunis par une articu­lation 3. Le premier panneau 1 dont la largeur est dans cet exemple la moitié de celle du deuxième panneau 2, c'est-à-dire le tiers de la largeur de la porte, est articulé sur le montant ou cadre 4 inscrit dans une ou­verture de la cloison 5. Le deuxième panneau est articulé sur le premier. Quand on ouvre la porte, le deuxième pan­neau 2 se replie contre le premier panneau 1. Il en ré­sulte deux avantages. Pendant l'ouverture, la porte balaye une surface réduite 6,et une fois ouverte, la porte ne déborde de la cloison que du tiers de sa largeur, de part et d'autre du plan de la cloison.The present invention relates to a folding door consisting of at least two panels hinged one on the other, allowing to release a wide opening, while occupying in the open position a reduced clearance. Figures 1 and 2 show in schematic horizontal section the operation of such a door. It consists of two panels, a first panel 1 and a second panel 2 joined by a hinge 3. The first panel 1 whose width in this example is half that of the second panel 2, that is to say the third of the width of the door, is articulated on the upright or frame 4 inscribed in an opening in the partition 5. The second panel is articulated on the first. When the door is opened, the second panel 2 folds back against the first panel 1. This has two advantages. During the opening, the door scans a reduced surface 6, and once opened, the door projects beyond the partition only by a third of its width, on either side of the plane of the partition.

Il peut y avoir plus de deux panneaux articu­lés.Mais l'intérêt ne croît pas avec le nombre des panneaux : la structure se complique, et la porte repliée occupe une épaisseur non négligeable qui limite sérieusement la largeur libre. C'est pourquoi dans la plupart des applications,on se limite à deux panneaux mais on com­prendra par la suite que la présente invention s'appli­que aussi bien aux portes constituées de 3 panneaux et davantage.There may be more than two hinged panels, but the interest does not increase with the number of panels: the structure is complicated, and the folded door occupies a significant thickness which seriously limits the free width. This is why in most applications, it is limited to two panels but it will be understood subsequently that the present invention applies equally well to doors made up of 3 panels and more.

Ces portes suscitent un grand intérêt de la clientèle. Mais les réalisations proposées jusqu'à pré­sent sont d'un prix élevé,qui en limite la diffusion. On voit immédiatement sur le dessin, que les panneaux cons­titutifs d'une porte se déplacent aussi bien d'un côté que de l'autre de la cloison. Une feuillure normale ne peut pas être utilisée, et ce d'autant plus que le deu­xième panneau 2 doit être de préférence guidé dans une glissière pratiquée dans le linteau de la porte, pour éviter un débattement désordonné.These doors arouse great interest from customers. But the achievements proposed so far are of a high price, which limits their dissemination. It is immediately seen in the drawing, that the panels constituting a door move as well on one side as on the other of the partition. A normal rebate cannot be used, all the more so since the second panel 2 must preferably be guided in a slide made in the lintel of the door, to avoid disorderly movement.

Il faut donc prévoir un cadre spécial pour une telle porte,ce qui est un facteur d'accroissement du prix de revient.It is therefore necessary to provide a special frame for such a door, which is a factor in increasing the cost price.

La présente invention a essentiellement pour but de proposer une porte présentant ces avantages, à un prix comparable à celui d'une porte ordinaire. L'in­vention prévoit principalement une telle porte pliante à débattement réduit, utilisant un cadre standard.The main object of the present invention is to propose a door having these advantages, at a price comparable to that of an ordinary door. The invention mainly provides such a folding door with reduced clearance, using a standard frame.

Pour obtenir ce résultat, l'invention a pour objet un ensemble de porte pliante du type comportant deux panneaux articulés l'un à l'autre, un premier panneau de faible largeur articulé sur un montant du cadre de la porte et un deuxième panneau de plus grande largeur articulé sur le premier, ce deuxième panneau en position d'ouverture de la porte venant se placer en travers du cadre, avec une partie de chaque côté de celui-ci, caractérisé en ce que la porte est utilisée en combinaison avec un cadre à feuillure classique et que l'articulation du premier panneau est située à une distance du montant suffisante pour permettre l'ouverture dudit premier panneau en sens opposé à la feuillure, de façon qu'en position de fermeture le bord du deuxième panneau vienne battre dans la feuillure, en permettant l'emploi d'une serrure classique, et en ce qu'il comporte en outre un profilé formé avec une rainure, ce profilé étant destiné à être placé dans la feuillure du linteau, de façon à permettre le glissement dans la rainure d'un doigt solidaire du deuxième panneau.To obtain this result, the invention relates to a folding door assembly of the type comprising two panels hinged to each other, a first panel of small width articulated on an upright of the door frame and a second panel of greater width articulated on the first, this second panel in the open position of the door coming to be placed across the frame, with a part on each side of it, characterized in that the door is used in combination with a conventional rebate frame and the articulation of the first panel is located at a distance from the upright sufficient to allow the opening of said first panel in the opposite direction to the rebate, so that in the closed position the edge of the second panel comes to beat in the rebate, allowing the use of a conventional lock, and in that it further comprises a profile formed with a groove, this profile being intended to be placed in the rebate of the lintel, of so as to allow sliding in the groove of a finger secured to the second panel.

De cette façon, le deuxième ou grand panneau s'ouvre par un geste habituel comme une porte ordinaire, avec une poignée près du bord et une serrure standard et non comme une porte de placard saisie par le centre. De plus, la venue du bord du panneau dans la feuillure permet une obturation de grande qualité, permettant l'emploi de la porte comme porte coupe-feu par exemple. Avantageusement, le deuxième panneau a une largeur égale au double de celle du premier. On obtient ainsi, avec deux panneaux, un débattement réduit au maximum, la porte en position ouverte n'avançant de chaque côté du cadre que d'un tiers de sa largeur.In this way, the second or large panel opens by a usual gesture like an ordinary door, with a handle near the edge and a standard lock and not like a cupboard door grabbed by the center. In addition, the coming of the edge of the panel in the rebate allows a high quality shutter, allowing the use of the door as a fire door for example. Advantageously, the second panel has a width equal to twice that of the first. There is thus obtained, with two panels, a clearance reduced to the maximum, the door in the open position advancing on each side of the frame only one third of its width.

D'autres caractéristiques et avantages de l'in­vention apparaîtront au cours de la description suivante donnée à titre d'exemple non limitatif, en regard des dessins ci-joints, d'un mode de réalisation de l'invention, et qui fera bien comprendre comment elle peut être mise en oeuvre.Other characteristics and advantages of the invention will appear during the following description given by way of nonlimiting example, with reference to the attached drawings, of an embodiment of the invention, and which will make it clear how it can be implemented.

La figure 3 est une vue en coupe d'un profilé métallique standard 10 pour cadre standard de porte d'in­térieur de locaux d'habitation. Il comporte une feuillure délimitée par les ailes 11 et 12 du profilé. La largeur de l'aile 12 définit l'épaisseur de la porte adaptable dans ce cadre. La largeur de l'aile 11 définit l'impor­tance du recouvrement entre la porte et le cadre dans les conditions standard.Figure 3 is a sectional view of a standard metal profile 10 for a standard interior door frame of living quarters. It comprises a rebate delimited by the wings 11 and 12 of the profile. The width of the wing 12 defines the thickness of the door that can be adapted within this framework. The width of the wing 11 defines the extent of the overlap between the door and the frame under standard conditions.

Conformément à la présente invention, pour pla­cer dans un tel cadre standard une porte pliante,ou arti­culée, selon l'invention, on utilise un profilé 15 (figure 4) formant un rail de guidage, et dont les dimensions correspondent sensiblement à celles de la feuillure.According to the present invention, to place in such a standard frame a folding door, or hinged, according to the invention, a profile 15 is used (Figure 4) forming a guide rail, and whose dimensions correspond substantially to those of the rabbet.

Dans la feuillure du linteau 16, on place une longueur du profilé 15 correspondant sensiblement à l'ouverture de la baie. La surface inférieure du lin­teau (figure 6) une fois garnie de ce profilé est alors sensiblement plane et définit le niveau supérieur de la porte, qui peut alors passer en-dessous et débat­tre d'un côté ou de l'autre. Le profilé 15 peut être soudé ou vissé au linteau, ou fixé autrement.In the rebate of the lintel 16, a length of the section 15 is placed corresponding substantially to the opening of the opening. The lower surface of the lintel (Figure 6) once filled with this profile is then substantially flat and defines the upper level of the door, which can then pass below and debate on one side or the other. The profile 15 can be welded or screwed to the lintel, or otherwise fixed.

Le premier panneau 1, dont la largeur est sensiblement égale au tiers de la largeur de la porte est articulé sur le cadre par deux pivots.The first panel 1, the width of which is substantially equal to one third of the width of the door is articulated on the frame by two pivots.

Un premier pivot supérieur comprend un doigt 20 (figure 7) engageable dans le trou 21 d'une platine 22 avantageusement fixée dans le profilé 15 (figure 6). A titre d'exemple, le doigt 20 peut coulisser dans un tu­be 23 logé dans l'épaisseur de la porte et être sollici­té vers le haut par un ressort 24. Pour enlever la porte, il suffit d'abaisser le doigt 20 par exemple au moyen d'un taquet 25 passant par une fente du tube 23 et une fente pratiquée dans la porte, et affleurant la surface de la tranche de celle-ci.A first upper pivot comprises a finger 20 (FIG. 7) which can be engaged in the hole 21 of a plate 22 advantageously fixed in the profile 15 (FIG. 6). For example, the finger 20 can slide in a tube 23 housed in the thickness of the door and be urged upwards by a spring 24. To remove the door, it suffices to lower the finger 20 for example to by means of a cleat 25 passing through a slit of the tube 23 and a slit made in the door, and flush with the surface of the edge thereof.

Un deuxième pivot inférieur (figures 9 et 10) peut être constitué par un bossage 30 formé sur une tôle emboutie 31, fixée à une équerre 32, elle-même fixée au montant 4 du cadre. Un bras de l'équerre est passé à l'intérieur du cadre par une découpure appropriée. La fi­xation peut être réalisée par vis, soudure ou autrement.A second lower pivot (Figures 9 and 10) may be constituted by a boss 30 formed on a stamped sheet 31, fixed to a bracket 32, itself fixed to the upright 4 of the frame. An arm of the square is passed inside the frame by an appropriate cutout. The fixing can be carried out by screws, welding or otherwise.

La figure 11 représente en coupe la contrepar­tie femelle 35 du pivot mâle 30. Ce peut être un chapeau en matière plastique, logé dans une cavité de forme corres­pondante formée dans le bas de la porte. Le frottement matière plastique sur métal se fait sans bruit, sans usure, sans lubrifiant. Une telle crapaudine supporte sans fatigue des charges élevées bien supérieures à celles que peuvent supporter des charnières. Le panneau 1 ainsi monté, suppor­tera sans inconvénient le deuxième panneau 2 par des char­nières convenables.Figure 11 shows in section the female counterpart 35 of the male pivot 30. It can be a plastic cap, housed in a correspondingly shaped cavity formed in the bottom of the door. The friction between plastic and metal is noise-free, wear-free and lubricant-free. Such a cradle easily withstands high loads much higher than those that can support hinges. The panel 1 thus mounted, will support the second panel 2 without drawbacks by suitable hinges.

Ces dispositions de pivots sont en elles-mêmes connues. Il en est fait application à la présente inven­tion. En particulier,le bossage 30 de même que le trou 21 de la platine 22 qui sont coaxiaux, sont situés à une cer­taine distance du montant 4, pour permettre au panneau 1 (représenté en pointillé sur la figure 9) de s'ouvrir vers le côté opposé à la feuillure. L'axe de pivotement est donc situé sensiblement dans le plan médian de la feuillure du cadre, et à une distance du bord intérieur de celui-ci égale à la moitié de l'épaisseur de la porte, dans le cas le plus raisonnable, ou l'axe de pivotement est placé à égale distance des deux faces.These pivot arrangements are known in themselves. Application is made to the present invention. In particular, the boss 30 as well as the hole 21 of the plate 22 which are coaxial, are located at a certain distance from the upright 4, to allow the panel 1 (shown in dotted lines in FIG. 9) to open towards the opposite side of the rebate. The pivot axis is therefore located substantially in the median plane of the frame rebate, and at a distance from the inner edge thereof equal to half the thickness of the door, in the most reasonable case, or the pivot axis is placed at equal distance from the two faces.

La figure 8 représente un doigt de guidage du deuxième panneau 2 articulé sur le premier. Le doigt comporte un axe 41 sur lequel est monté rotatif un galet 42 par exemple en matière plastique. Le galet 42 tourne librement à l'intérieur du profilé 15, avec un minimum de jeu. L'axe 41 peut tout simplement être vissé dans le haut du panneau 2, au milieu de la largeur. Ce galet sert simplement au guidage de la porte. Il n'est pas porteur, il ne supporte pas le panneau 2. Celui-ci est supporté par le panneau 1,par des charnières appropriées 51, 52, 53.FIG. 8 represents a guide finger of the second panel 2 articulated on the first. The finger has an axis 41 on which a roller 42, for example made of plastic, is rotatably mounted. The roller 42 rotates freely inside the profile 15, with a minimum of play. The axis 41 can simply be screwed into the top of the panel 2, in the middle of the width. This roller is simply used to guide the door. It is not a carrier, it does not support the panel 2. This is supported by the panel 1, by appropriate hinges 51, 52, 53.

La figure 12 représente schématiquement la por­te en place dans son cadre. Le panneau 1 est articulé par le pivot inférieur constitué du chapeau 35 reposant sur le bossage 30,et par le pivot supérieur constitué du doigt 20 engagé dans le trou 21 de la platine 22, fixée au pro­filé 15 lui-même fixé au profilé formant le linteau 16. Le deuxième panneau 2 est articulé sur le premier par exemple par trois charnières 51, 52, 53, du type permettant de rabattre complètement un panneau contre l'autre. Le pan­neau 2 est en outre guidé par le galet 42 glissant dans le profilé 15.Figure 12 shows schematically the door in place in its frame. The panel 1 is articulated by the lower pivot constituted by the cap 35 resting on the boss 30, and by the upper pivot constituted by the finger 20 engaged in the hole 21 of the plate 22, fixed to the profile 15 itself fixed to the profile forming the lintel 16. The second panel 2 is articulated on the first, for example by three hinges 51, 52, 53, of the type allowing one panel to be completely folded against the other. The panel 2 is further guided by the roller 42 sliding in the profile 15.

Enfin une serrure 55 permet de maintenir la porte en position fermée. On remarquera que c'est une serrure usuelle, du type utilisé normalement sur les portes clas­siques en un seul battant. Elle s'ouvre, avec la porte, par un geste habituel, comme pour une porte classique, et non comme une porte de placard, repliable en V, qui est saisie par le milieu.Finally, a lock 55 keeps the door in the closed position. Note that it is a usual lock, of the type normally used on conventional doors with a single leaf. It opens, with the door, by a usual gesture, as for a traditional door, and not as a cupboard door, foldable in V, which is gripped by the middle.

La description a été faite en se référant à un cadre formé d'un profilé métallique. L'invention s'appli­que tout aussi bien sur n'importe quelle feuillure de cadre de tout type, en métal ou en bois. En particulier, l'invention permet de remplacer toute porte existante par une porte pliante, avec un minimum de dépense. Pour des raisons de simplicité, de robustesse et d'éco­nomie, le profilé 15 sera en métal, bien qu'un profilé en bois (une baguette) avec une rainure et un trou 21 peut très bien fonctionner.The description has been made with reference to a frame formed by a metal profile. The invention applies equally well to any frame rebate of any type, made of metal or wood. In particular, the invention makes it possible to replace any existing door with a folding door, with a minimum of expense. For reasons of simplicity, robustness and economy, the profile 15 will be made of metal, although a wooden profile (a rod) with a groove and a hole 21 can work very well.

L'esprit de l'invention est essentiellement à voir dans l'usage d'un cadre conventionnel, recevant une porte pliante, à débattement réduit.The spirit of the invention is essentially to be seen in the use of a conventional frame, receiving a folding door, with reduced clearance.

La porte pliante selon l'invention se monte avantageusement avec deux pivots, de préférence à des paumelles usuelles, les pivots étant à l'écart suffisant pour permettre l'ouverture du premier panneau en direction opposée à la feuillure, et avec l'adjonction du profilé supérieur 15, avec le galet 42 correspondant au milieu du deuxième panneau 2.The folding door according to the invention is advantageously mounted with two pivots, preferably with conventional hinges, the pivots being at a sufficient distance to allow the opening of the first panel in the direction opposite to the rebate, and with the addition of the upper section 15, with the roller 42 corresponding to the middle of the second panel 2.

Les figures 13 et 14 représentent en coupe hori­zontale une porte selon l'invention à l'état fermé, et à l'état entr'ouvert, respectivement. Dans cet exemple, on a representé les panneaux articulés par des paumelles. La paumelle 61, reliant le panneau 1 au montant 4 n'est pas placée à l'endroit habituel, mais est écartée du bord du panneau 1 pour permettre son ouverture en sens inverse de la feuillure. Le bord extérieur 56 du panneau large 2 vient battre (flèche F) dans la feuillure 57 du montant 4', dans des conditions similaires à celles d'une porte ordinaire. La porte selon l'invention est normalement équipée d'une serrure 55 standard, absolument normale, et assurant la fermeture et le blocage de la porte comme pour une porte ordinaire. En effet, le déplacement initial du bord 56 du panneau 2, lors de l'ouverture, est per­pendiculaire au plan du cadre 4, avec seulement un rayon de rotation plus court. L'ouverture se fait par un geste habituel.Figures 13 and 14 show in horizontal section a door according to the invention in the closed state, and in the half-open state, respectively. In this example, the panels articulated by hinges have been shown. The hinge 61, connecting the panel 1 to the upright 4 is not placed in the usual place, but is moved away from the edge of the panel 1 to allow its opening in the opposite direction of the rebate. The outer edge 56 of the wide panel 2 flaps (arrow F) in the rebate 57 of the upright 4 ', under conditions similar to those of an ordinary door. The door according to the invention is normally equipped with a standard lock 55, absolutely normal, and ensuring the closing and locking of the door as for an ordinary door. In fact, the initial movement of the edge 56 of the panel 2, during opening, is perpendicular to the plane of the frame 4, with only a shorter radius of rotation. The opening is done by a usual gesture.

On voit que l'on peut utiliser un cadre standard et même pour le deuxième panneau une porte standard, raccourcie de l'épaisseur du premier panneau. On a donc réalisé une porte à faible surface balayée, et à faible débattement procurant ainsi un avantage important pour les fermetures de locaux exigus (WC, dégagements, etc.) fréquents dans les logements modernes, pour un supplément de prix étonnamment peu élevé, par rapport à une porte ordinaire. En particuler, une porte selon l'invention peut être mise à la place d'une porte classique à tout moment, à la conception d'un logement, à la mise en service, ou postérieurement. L'architecte concepteur n'a pas à réserver les emplacements qui seront munis de telles portes. On peut aussi, avec deux portes pliantes, réaliser la fermeture d'une baie large, c'est-­à-dire l'équivalent d'une cloison escamotable.We see that we can use a standard frame and even for the second panel a standard door, shortened by the thickness of the first panel. We therefore produced a door with a small swept surface and low clearance, thus providing an important advantage for closings of tight spaces (toilets, clearances, etc.) frequent in modern housing, for a surprisingly low price supplement, by compared to an ordinary door. In particular, a door according to the invention can be replaced in place of a conventional door at any time, when designing a housing, when it is put into service, or afterwards. The designer architect does not have to reserve the sites which will be fitted with such doors. It is also possible, with two folding doors, to close a wide opening, that is to say the equivalent of a retractable partition.
