Description

La présente invention concerne les portes étanches coulissantes et leurs dispositifs de suspension, de telles portes étant utilisées, notamment pour des enceintes dans lesquelles doivent être maintenues une température et/ou une atmosphère déterminées.The present invention relates to watertight sliding doors and their suspension devices, such doors being used, in particular for enclosures in which a determined temperature and / or atmosphere must be maintained.

Le Document DE-A-2 616 495 décrit un dispositif de suspension d'une porte étanche coulissante comprenant un rail de guidage ayant une section transversale en forme générale de C, fixé sur un mur et délimitant deux surfaces de guidage, dont l'une comporte des encoches avec lesquelles coopèrent au moins des éléments de roulement ou de glissement portés par des moyens de support de la porte, et dont l'autre coopère avec d'autres éléments de roulement ou glissement portés par un bras relié à la porte, ce bras étant disposé entièrement à l'intérieur du rail à section en C et travaillant en compression, les deux surfaces de roulement étant situées sur un même niveau dans un même plan.Document DE-A-2 616 495 describes a device for suspending a sliding waterproof door comprising a guide rail having a cross section in the general shape of C, fixed to a wall and delimiting two guide surfaces, one of which has notches with which at least the rolling or sliding elements carried by the door support means cooperate, and the other of which cooperates with other rolling or sliding elements carried by an arm connected to the door, this arm being disposed entirely inside the C-section rail and working in compression, the two rolling surfaces being located on the same level in the same plane.

D'autre part, un dispositif de suspension d'une porte étanche coulissante de construction simple et peu coûteuse permettant d'obtenir une force de fermeture de la porte sensiblement accrue par rapport à ce qui était déjà obtenu dans les systèmes de l'art antérieur est décrit dans la demande de brevet FR-A-2 208 436. Dans ce dispositif, le moyen de support de la porte est essentiellement constitué par un bras de traction dont une première extrémité coopère avec un premier organe de guidage solidaire du mur, par rapport auquel il peut se déplacer angulairement et en translation et dont l'autre extrémité supporte de façon oscillante la porte proprement dite.On the other hand, a device for suspending a sealed sliding door of simple and inexpensive construction making it possible to obtain a closing force of the door significantly increased compared to what was already obtained in the systems of the prior art. is described in patent application FR-A-2 208 436. In this device, the door support means essentially consists of a traction arm, a first end of which cooperates with a first guide member secured to the wall, by ratio in which it can move angularly and in translation and the other end of which supports the door itself in oscillating fashion.

Le dispositif comprend également un deuxième rail de guidage fixé au mur, dont la surface de guidage délimite au moins une rampe ou une encoche avec laquelle coopère au moins un galet ou élément de roulement ou de glissement porté par des moyens de support de la porte.The device also comprises a second guide rail fixed to the wall, the guide surface of which delimits at least one ramp or a notch with which at least one roller or rolling or sliding element cooperates carried by means of supporting the door.

Toujours dans ce dispositif, l'angle formé par le bras de traction avec l'horizontale permet lorsque le galet situé sur le deuxième rail de guidage tombe dans une encoche, d'engendrer une force d'application de la porte sur le dormant égale à 1,4 jusqu'à 1,7, fois le poids de la porte, ce qui naturellement est favorable à l'obtention d'une bonne étanchéité.Also in this device, the angle formed by the traction arm with the horizontal allows when the roller located on the second guide rail falls into a notch, to generate a force for applying the door on the frame equal to 1.4 to 1.7 times the weight of the door, which naturally favors obtaining a good seal.

Un perfectionnement à ce dispositif est décrit dans le certificat d'addition FR-A-2 361 518.An improvement to this device is described in the addition certificate FR-A-2 361 518.

Ce perfectionnement consiste à remplacer les deux rails de guidage par un profilé en forme de Cfixé contre le mur, le bord de l'aile inférieure du C formant la surface dudit deuxième rail de guidage, et la partie supérieure du C délimitant une surface de roulement dirigée vers l'intérieur du profilé et constituant ledit premier rail de guidage. Cette solution simplifie notablement la fabrication du dispositif de suspension et en diminue par conséquent le prix de revient.This improvement consists in replacing the two guide rails by a C-shaped profile fixed against the wall, the edge of the lower wing of the C forming the surface of said second guide rail, and the upper part of the C delimiting a rolling surface. directed towards the inside of the profile and constituting said first guide rail. This solution significantly simplifies the manufacture of the suspension device and consequently reduces the cost price.

Aussi perfectionné que soit ce dernier dispositif, il présente toutefois les inconvénients suivants. En premier lieu, la position du galet d'extrémité du bras de traction qui est toujours au dessus de celle du galet roulant sur l'aile inférieure du C, impose une distance vers le haut non négligeable entre le bord de l'aile inférieur du C et sa partie supérieure. Ceci se traduit par un manque de compacité de l'ensemble galets, bras de traction et profilé en C, qui a pour conséquence de rendre trop important l'espace qui doit être réservé au profilé en C au-dessus de la porte étanche, la réservation de cet-espace se faisant naturellement au détriment de la hauteur disponible pour la porte elle-même.As sophisticated as this latter device is, it nevertheless has the following drawbacks. Firstly, the position of the end roller of the traction arm which is always above that of the roller running on the lower wing of the C, imposes a significant upward distance between the edge of the lower wing of the C and its upper part. This results in a lack of compactness of the rollers, traction arm and C-profile assembly, which has the consequence of making too much space which must be reserved for the C-profile above the watertight door, the reservation of this space is done naturally at the expense of the height available for the door itself.

En deuxième lieu l'angle d'inclinaison formé par le bras de traction avec l'horizontale, lorsque la porte est en position ouverte augmente d'une quantité ,"\' lorsque la porte passe en position fermée, ce qui limite l'efficacité maximum de la force de fermeture è celle obtenue pour l'angle résiduel.Secondly, the angle of inclination formed by the traction arm with the horizontal, when the door is in the open position increases by an amount, "\ 'when the door moves to the closed position, which limits the efficiency. maximum closing force to that obtained for the residual angle.

Enfin, le point d'articulation du bras de traction sur la porte se trouvant à l'extérieur du profilé en forme de C expose les galets de suspension aux poussières, ce qui nécessite le montage d'un profilé extérieur ou carter de protection qui augmente d'autant le prix de revient de l'ensemble.Finally, the point of articulation of the traction arm on the door located outside the C-shaped profile exposes the suspension rollers to dust, which requires the mounting of an outer profile or protective casing which increases all the more the cost price of the whole.

Le but de la présente invention est d'apporter des perfectionnements aux dispositifs ci-dessus en vue d'obtenir un dispositif plus compact, une plus grande efficacité de fermeture, et un meilleur aspect extérieur, tout en réduisant son prix de revient.The object of the present invention is to provide improvements to the above devices with a view to obtaining a more compact device, greater closing efficiency, and a better external appearance, while reducing its cost price.

A cet effet conformément à l'invention, l'axe d'oscillation du ou de chaque bras de compression est situé au-dessus des galets.For this purpose in accordance with the invention, the axis of oscillation of the or each compression arm is located above the rollers.

L'avantage de cette disposition selon laquelle l'axe d'oscillation se trouve situé au-dessus des galets, réside en ce que l'angle que forme le bras oscillant lors de la fermeture de la porte est inférieur à celui qui correspond à la porte ouverte, ce qui augmente l'efficacité de la force de fermeture.The advantage of this arrangement, according to which the axis of oscillation is located above the rollers, is that the angle formed by the swinging arm when the door is closed is less than that which corresponds to the door open, which increases the efficiency of the closing force.

Suivant une autre caractéristique de l'invention, le ou chaque bras de compression comprend une première extrémité articulée sur une tige reliée à la porte dont l'axe longitudinal est orientée dans une direction parallèle à l'axe du rail de guidage, et une seconde extrémité munie d'une tige sur laquelle est fixée en rotation un galet coopérant avec la surface de guidage ne comportant pas d'encoches.According to another characteristic of the invention, the or each compression arm comprises a first end articulated on a rod connected to the door whose longitudinal axis is oriented in a direction parallel to the axis of the guide rail, and a second end provided with a rod on which is fixed in rotation a roller cooperating with the guide surface having no notches.

Suivant un mode de réalisation préféré de l'invention, la porte est montée sur des ferrures reliées de façon oscillante au bras de compression et qui supportent le ou chaque élément de roulement ou de glissement coopérant avec la première surface de guidage.According to a preferred embodiment of the invention, the door is mounted on fittings connected in an oscillating manner to the compression arm and which support the or each rolling or sliding element cooperating with the first guide surface.

De préférence, les bras de compression sont inclinés sur l'horizontale d'un angle inférieur à 45° lorsque la porte est en position de fermeture.Preferably, the compression arms are inclined to the horizontal by an angle less than 45 ° when the door is in the closed position.

L'invention sera mieux comprise à l'aide de la description qui va suivre donnée à titre d'exemple et faite en se référant aux dessins annexés, sur lesquels:

  • - la Fig. 1 est une vue schématique montrant la décomposition des forces lorsque la porte est en équilibre sur le rail de guidage;

  • - la Fig. 5 est une vue en coupe du dispositif de suspension suivant la ligne 5-5 de la Fig. 4.
The invention will be better understood with the aid of the description which follows, given by way of example and made with reference to the appended drawings, in which:
  • - Fig. 1 is a schematic view showing the breakdown of the forces when the door is balanced on the guide rail;
  • - Figs. 2A and 2B schematically represent the positions of the door relative to the guide rail in the respectively closed and open positions;

La porte P et ses dispositifs de suspension sont représentés de façon schématique aux Fig. 1 et 2A, 2B. Sur ces figures, la porte P est suspendue à un rail de guidage 1 par l'intermédiaire de dispositifs de suspension S comprenant chacun deux galets G, et Gz qui aussurent le déplacement longitudinal de la porte, par roulement sur le rail de guidage. Dans le rail de guidage sont ménagées des encoches 2 dans lesquelles tombent les galets G1 lorsque la porte est dans la position fermée de la Fig. 2A.Door P and its suspension devices are shown diagrammatically in FIGS. 1 and 2A, 2B. In these figures, the door P is suspended from a guide rail 1 by means of suspension devices S each comprising two rollers G, and Gz which also have the longitudinal movement of the door, by rolling on the guide rail. In the guide rail are provided notches 2 into which the rollers G 1 fall when the door is in the closed position of FIG. 2A.

Les détails de réalisation de chaque dispositif de suspension S et sa coopération avec la porte P et le rail de guidage sont représentés aux Fig. 3 à 5. La porte est représentée en position ouverte sur la Fig. 3. Elle est représentée en position fermée reposant sur ses bourrelets d'étanchéité B à la Fig. 4.The construction details of each suspension device S and its cooperation with the door P and the guide rail are shown in Figs. 3 to 5. The door is shown in the open position in FIG. 3. It is shown in the closed position resting on its sealing beads B in FIG. 4.

Sur ces figures, le rail de guidage 1 est constitué par un profilé en forme de C couché, ouvert vers le bas, et maintenu appliqué au mur M par une première aile 1a, par l'intermédiaire d'une ferrure 4 et d'une aile 5a d'une équerre 5, l'ensemble étant serré par une vis 6 qui les traverse et est vissée dans le mur M.In these figures, the guide rail 1 is constituted by a C-shaped section lying down, open downwards, and kept applied to the wall M by a first wing 1a, by means of a fitting 4 and a wing 5a of a bracket 5, the assembly being tightened by a screw 6 which passes through them and is screwed into the wall M.

Le rail de guidage 1 est également fixé par son âme supérieure 1 à l'aile supérieure 5b de l'équerre 5 par l'intermédiaire d'un moyen de fixation 7, de façon que l'âme 1 soit plane et à peu près horizontale. L'extrémité libre 1 c de l'aile 1a du rail 1 est repliée obliquement vers l'intérieur du C et forme un angle voisin de 45° avec l'horizontale de façon à constituer une surface de guidage plane 8 interne au profilé C.The guide rail 1 is also fixed by its upper core 1 to the upper wing 5b of the bracket 5 by means of a fixing means 7, so that the core 1 is flat and more or less horizontal . The free end 1c of the wing 1a of the rail 1 is folded obliquely towards the inside of the C and forms an angle close to 45 ° with the horizontal so as to constitute a flat guide surface 8 internal to the profile C.

La surface de guidage 8 et l'aile 1c présentent également en deux emplacements prédéterminés les encoches 2 que l'on peut voir sur la Fig. 4. L'aile du C opposée au mur M comprend deux parties 1 d et 1 e formant entre elles un angle obtus. La partie 1d est adjacente à l'âme 1b. La partie 1e s'étend parallèlement à l'aile 1a et se termine à son extrémité libre par un rebord 1f dirigé vers l'intérieur du profilé, ce rebord délimitant dans l'angle formé intérieurement avec la partie adjacente 1e, une surface de roulement 9 à section en arc de cercle située à l'intérieur du rail de guidage 1 et constituant ainsi une deuxième surface de guidage dont le plan moyen est à peu près perpendiculaire à la surface de guidage 8. Sur la surface de guidage 8 roule le galet Gi monté fou autour d'une bague 10 qui est fixée par un boulon 11 à une aile supérieure oblique 13a d'un profilé 13 en V. L'aile inférieure 13b du profilé 13 est à peu près horizontale et fixée au bord supérieur de la porte P à l'aide d'un moyen de fixation 14.The guide surface 8 and the wing 1c also have, at two predetermined locations, the notches 2 which can be seen in FIG. 4. The wing of C opposite the wall M comprises two parts 1 d and 1 e forming between them an obtuse angle. The part 1d is adjacent to the core 1b. Part 1e extends parallel to wing 1a and ends at its free end with a rim 1f directed towards the inside of the profile, this rim delimiting in the angle formed internally with the adjacent part 1e, a rolling surface. 9 with a circular arc section located inside the guide rail 1 and thus constituting a second guide surface whose mean plane is approximately perpendicular to the guide surface 8. On the guide surface 8 rolls the roller Gi mounted idly around a ring 10 which is fixed by a bolt 11 to an oblique upper wing 13a of a profile 13 in V. The lower wing 13b of profile 13 is roughly horizontal and fixed to the upper edge of the door P by means of a fixing means 14.

L'aile oblique 13a supporte également un dispositif support du galet Gz composé de deux équerres 15 et 16, (Fig. 5) à ailes perpendiculaires. Les ailes 15a et 16a de ces équerres sont fixées sur l'aile 13a à l'aide de moyens de serrage 17 et 18. Les autres ailes 15b et 16b sont maintenues écartées parallèlement l'une à l'autre par une entretoise 19 et une tige 20, les axes longitudinaux de l'entretoise 19 et de la tige 20 étant disposés parallèlement à l'axe longitudinal du rail de guidage 1. Sur la tige 20 est articulée l'âme 21a a d'un bras de compression 21 en forme de chape entre les jambes 21b et 21c duquel tourillonne, sur une tige 22 perpendiculaire à la tige 20, le galet Gz. Ce galet Gz repose sur la surface de roulement 9 et possède une surface périphérique torique, ce qui permet un déplacement angulaire de l'axe du galet Gz par rapport à la surface 9. La tige 20 se trouve au-dessus des galets Gi et G2, près de l'âme 1b du C; les plans moyens des deux galets se coupent au voisinage de cette tige et sont inclinés à peu près d'un même angle sur la verticale.The oblique wing 13a also supports a roller support device G z made up of two brackets 15 and 16, (Fig. 5) with perpendicular wings. The wings 15a and 16a of these brackets are fixed to the wing 13a by means of clamping means 17 and 18. The other wings 15b and 16b are held apart apart from one another by a spacer 19 and a rod 20, the longitudinal axes of the spacer 19 and of the rod 20 being arranged parallel to the longitudinal axis of the guide rail 1. On the rod 20 is articulated the core 21a has a compression arm 21 in the form yoke between the legs 21b and 21c from which pivots, on a rod 22 perpendicular to the rod 20, the roller Gz. This roller G z rests on the rolling surface 9 and has a toric peripheral surface, which allows an angular displacement of the axis of the roller G z relative to the surface 9. The rod 20 is located above the rollers Gi and G 2 , near the core 1b of C; the mean planes of the two rollers intersect in the vicinity of this rod and are inclined at about the same angle on the vertical.

Le fonctionnement du dispositif est décrit ci-après. Lorsque la porte est en position de translation, c'est-à-dire en position d'ouverture partielle ou totale, le dispositif a la configuration représentée à la Fig. 3. Lors de la translation de la porte, les galets G1, G2 roulent respectivement le long de leur chemin de guidage 8 et 9. Lorsque la porte parvient au voisinage ou dans sa position de fermeture, les galets Gi tombent dans les encoches 2 de l'aile 1a, ce qui provoque un déplacement de la porte vers le sol et vers le mur. Lors de ce déplacement, l'angle formé par les plans moyens des galets Gi et G2 augmente d'une valeur a d'environ 15° pour prendre la position représentée sur la Fig.4 où l'on peut voir que les galets G2 ont basculé autour de leur point d'appui sur la surface de roulement 9.The operation of the device is described below. When the door is in the translational position, that is to say in the partial or total open position, the device has the configuration shown in FIG. 3. During the translation of the door, the rollers G 1 , G 2 roll respectively along their guide path 8 and 9. When the door reaches the vicinity or in its closed position, the rollers G i fall into the notches 2 of wing 1a, which causes the door to move towards the floor and towards the wall. During this movement, the angle formed by the mean planes of the rollers G i and G 2 increases by a value a of approximately 15 ° to take the position shown in Fig.4 where it can be seen that the rollers G 2 have tilted around their fulcrum on the rolling surface 9.

En se reportant à la Fig. 1, on peut examiner comment s'effectue la décomposition des forces lorsque la porte est en position de fermeture. Le poids Po de la porte, transmis par le profilé 13, s'exerce sur la tige 20. Sa ligne d'action, à partir de cette tige passe entre les galets Gi et Gz. Si l'on suppose que la surface de roulement 8 n'intervient pratiquement pas dans la transmission des efforts, ce qui est effectivement le cas dans la réalité du fait de l'appui des bourrelets B sur le mur M, le poids Po de la porte peut se décomposer en une composante PT dirigée suivant le bras de compression 21 et une composante horizontale PH. On voit sur la Fig. 1 que si β représente l'angle que forme le bras de compression par rapport à l'horizontale lorsque la porte se trouve en position de fermeture, la composante horizontale PH du poids qui est égale à

Figure imgb0001
, est supérieure à Po si l'on prend la précaution de choisir un angleginférieur à 45°.Referring to FIG. 1, we can examine how the forces are broken down when the door is in the closed position. The weight Po of the door, transmitted by the profile 13, is exerted on the rod 20. Its line of action, from this rod passes between the rollers Gi and Gz. If it is assumed that the rolling surface 8 practically does not intervene in the transmission of forces, which is actually the case in reality due to the support of the beads B on the wall M, the weight Po of the door can be broken down into a component P T directed along the compression arm 21 and a horizontal component P H. We see in Fig. 1 that if β represents the angle formed by the compression arm with respect to the horizontal when the door is in the closed position, the horizontal component zontale P H of the weight which is equal to
Figure imgb0001
 , is greater than Po if we take the precaution of choosing an angle less than 45 °.

Dans sa partie inférieure, la porte est guidée par des galets 30 de forme conique et d'axe vertical, dont la génératrice la plus proche du mur est inclinée par rapport à la verticale de l'angle ,8 précité. De la sorte, la réaction exercée par le mur sur la partie inférieure de la porte est absorbée par les galets de guidage inférieurs.In its lower part, the door is guided by rollers 30 of conical shape and vertical axis, the generatrix closest to the wall is inclined relative to the vertical of the angle, 8 above. In this way, the reaction exerted by the wall on the lower part of the door is absorbed by the lower guide rollers.

En revenant au dispositif représenté aux Fig. 3 et 4, le bras de compression 21 fait un angle β avec l'horizontale lorsque la porte est en position fermée et un angle α+β lorsque celle-ci est en position ouverte. L'angle d'inclinaison du bras de compression avec l'horizontale est donc minimal lorsque la porte se trouve en position fermée, et cette situation est naturellement favorable à une plus grande efficacité de la force de fermeture de la porte. On notera qu'avec le dispositif de l'invention tel qu'il vient d'être décrit, il est toujours possible d'obtenir des valeurs de ,8 quelconques entre 0 et 45° en augmentant par exemple la distance entre les deux ailes du C et/ou en remontant le rebord 1f du même profilé.Returning to the device shown in Figs. 3 and 4, the compression arm 21 makes an angle β with the horizontal when the door is in the closed position and an angle α + β when the latter is in the open position. The angle of inclination of the compression arm with the horizontal is therefore minimal when the door is in the closed position, and this situation is naturally favorable to greater efficiency of the closing force of the door. It will be noted that with the device of the invention as just described, it is always possible to obtain values of any 8 between 0 and 45 ° by increasing for example the distance between the two wings of the C and / or by raising the rim 1f of the same profile.
