Description

La présente invention concerne une porte coulissante à ouverture d'urgence, du genre utilisé pour la fermeture de vastes locaux destinés à recevoir simultanément un grand nombre de personnes.The present invention relates to a sliding door with emergency opening, of the type used for closing large premises intended to accommodate a large number of people simultaneously.

De telles portes comprennent généralement un vantail, ou deux vantaux se faisant vis-à-vis, chaque vantail étant constitué d'un panneau fixe par rapport à un bâti lié à l'encadrement de la porte par articulation, et d'au moins un panneau mobile relié au bâti par l'intermédiaire d'un chemin de roulement permettant au panneau mobile de coulisser parallèlement au panneau fixe. Le panneau mobile est normalement en position de fermeture, et il coulisse automatiquement en position d'ouverture à l'approche d'une personne.Such doors generally include a leaf, or two leaves facing each other, each leaf consisting of a panel fixed relative to a frame linked to the frame of the door by articulation, and at least one mobile panel connected to the frame via a raceway allowing the mobile panel to slide parallel to the fixed panel. The movable panel is normally in the closed position, and it slides automatically into the open position when a person approaches.

Toutefois, ce mouvement de coulissement est relativement lent, en vue d'assurer une bonne tenue du matériel, et si des occupants du local, pris de panique pour une raison quelconque, se précipitent sur la porte, ils peuvent s'y appuyer avant son ouverture totale, empêchant ainsi la poursuite du mouvement de coulissement.However, this sliding movement is relatively slow, in order to ensure that the equipment is well maintained, and if the occupants of the room, panicking for some reason, rush onto the door, they can lean against it before it total opening, thus preventing the sliding movement from continuing.

On a cherché à remédier à cet inconvénient en donnant au panneau mobile un degré de liberté de rotation pour lui permettre de s'ouvrir comme un vantail traditionnel, vers l'extérieur du local, quand on excerce une pression sur lui. Mais plusieurs inconvénients subsistent. D'une part, les règlements de sécurité imposent une rotation d'amplitude supérieure à 90°, de sorte qu'une fois le panneau mobile ouvert il présente un encombrement qui interdit d'ouvrir de la même manière le panneau fixe. L'ouverture obtenue est donc limitée à la largeur du panneau mobile.We sought to remedy this drawback by giving the movable panel a degree of freedom of rotation to allow it to open like a traditional leaf, towards the outside of the room, when pressure is exerted on it. But several drawbacks remain. On the one hand, the safety regulations impose an amplitude rotation greater than 90 °, so that once the movable panel is open, it has a bulk which prevents the fixed panel from being opened in the same way. The opening obtained is therefore limited to the width of the movable panel.

D'autre part, pour cette opération, le panneau mobile doit pouvoir tourillonner en haut et en bas, en particulier dans le plancher. Pour rendre le mouvement rotatif compatible avec le mouvement normal de coulissement, on prévoit de loger le tourillon inférieur dans une gorge du plancher qui autorise les deux mouvements. Mais, en particulier dans les lieux publics, cette gorge est constamment exposée à être encrassée par des détritus divers qui compromettent le fonctionnement de la porte.On the other hand, for this operation, the movable panel must be able to swivel up and down, in particular in the floor. To make the rotary movement compatible with the normal sliding movement, provision is made to accommodate the lower pin in a groove in the floor which allows the two movements. But, especially in public places, this groove is constantly exposed to being clogged with various detritus which compromise the functioning of the door.

Une solution partielle est donnée à ces problèmes par le DE-A-2 322 907. Selon ce document, le panneau mobile est relié par un ergot à une chaîne sans fin actionnée par un moteur. L'ergot est engagé librement et latéralement dans la chaîne, de sorte que l'actionnement en rotation de la porte dégage l'ergot de la chaîne. Mais le mécanisme d'entraînement (chaîne et moteur) n'accompagne pas la porte et encombre en permanence la partie supérieure du passage. En outre, pendant la rotation, la rétraction coulissante du panneau mobile est obtenue par une bielle fixée d'une part au panneau mobile et d'autre part au linteau. Pendant la rotation, la bielle tire le panneau mobile en position retractée. Un tel système n'est pas d'une fiabilité absolue et peut conduire à des coincements.A partial solution is given to these problems by DE-A-2 322 907. According to this document, the movable panel is connected by a lug to an endless chain actuated by a motor. The lug is freely and laterally engaged in the chain, so that the actuation in rotation of the door releases the lug from the chain. But the drive mechanism (chain and motor) does not accompany the door and permanently clogs the upper part of the passage. In addition, during rotation, the sliding retraction of the movable panel is obtained by a connecting rod fixed on the one hand to the movable panel and on the other hand to the lintel. During rotation, the connecting rod pulls the movable panel into the retracted position. Such a system is not absolutely reliable and can lead to jamming.

La présente invention vise à réaliser une porte coulissante à ouverture d'urgence qui permette de dégager le plus grand espace possible et présente une fiabilité optimale.The present invention aims to provide a sliding door with emergency opening which makes it possible to free up the largest possible space and has optimum reliability.

Suivant l'invention, la porte coulissante à ouverture d'urgence comprend au moins un vantail constitué d'un panneau fixe par rapport à un bâti lié à l'encadrement de la porte et d'au moins un panneau mobile relié au bâti par l'intermédiaire d'un chemin de roulement permettant au panneau mobile de coulisser parallèlement au panneau fixe. Cette porte comprend un système d'articulation pour permettre un mouvement de rotation des panneaux autour d'un axe vertical, et elle est caractérisée en ce que les moyens moteurs de coulissement sont fixés au bâti pour être entraînés solidairement avec le bâti dans son mouvement de rotation.According to the invention, the sliding door with emergency opening comprises at least one leaf consisting of a fixed panel with respect to a frame linked to the frame of the door and at least one movable panel connected to the frame by the 'through a raceway allowing the movable panel to slide parallel to the fixed panel. This door includes an articulation system to allow a rotational movement of the panels about a vertical axis, and it is characterized in that the sliding motor means are fixed to the frame to be driven integrally with the frame in its movement of rotation.

Le périmètre de l'encadrement est entièrement dégagé puisque non seulement les deux panneaux, mobile est fixe, mais également le bâti et les moyens moteurs de coulissement sont affectés par le mouvement de rotation.The perimeter of the frame is entirely cleared since not only the two panels, mobile is fixed, but also the frame and the sliding motor means are affected by the rotational movement.

L'ouverture dégagée est donc maximale, aussi bien en hauteur que latéralement.The clear opening is therefore maximum, both in height and laterally.

Suivant une réalisation perfectionnée de l'invention, la porte comprend un étage de commande des moyens moteurs pour provoquer automatiquement le coulissement du panneau mobile dans le sens de l'ouverture quand le vantail est sollicité en rotation dans le sens de l'ouverture.According to an improved embodiment of the invention, the door comprises a stage for controlling the motor means for automatically causing the sliding of the movable panel in the direction of opening when the leaf is rotated in the direction of opening.

Une fois la porte ouverte par rotation, le panneau mobile est ainsi ramené sur le panneau fixe, ce qui diminue de moitié la prise au vent et réduit les risques de bris en diminuant l'encombrement.Once the door is opened by rotation, the movable panel is thus brought back to the fixed panel, which halves the wind resistance and reduces the risk of breakage by reducing the size.

De préférence, l'étage de commande des moyens moteurs comprend un dispositif pour actionner les moyens moteurs à une vitesse inférieure à la vitesse normale de coulissement quand le vantail est sollicité en rotation dans le sens de l'ouverture.Preferably, the motor means control stage comprises a device for actuating the motor means at a speed lower than the normal sliding speed when the leaf is rotated in the direction of opening.

Pendant l'ouverture rotative de la porte, le coulissement à vitesse lente évite de causer des blessures à la foule qui se précipite en s'appuyant contre les panneaux.Sliding at low speed during the rotary opening of the door avoids causing injury to the rushing crowd leaning against the panels.

Suivant une réalisation avantageuse de l'invention, la porte comprend des moyens élastiques pour s'opposer au mouvement de rotation du vantail dans le sens de l'ouverture pendant une fraction de la course rotative dudit vantail voisine de sa position de fermeture.According to an advantageous embodiment of the invention, the door comprises elastic means for opposing the movement of rotation of the leaf in the direction of opening during a fraction of the rotary stroke of said leaf close to its closed position.

Après une poussée fugitive ayant provoqué l'entrebaillement de la porte, celle-ci se referme automatiquement par l'effet des moyens élastiques si cette poussée n'est pas poursuivie.After a fugitive push having caused the door to open, the latter closes automatically by the effect of elastic means if this push is not continued.

De la même manière, la porte comprend des moyens élastiques pour provoquer le mouvement de rotation du vantail dans le sens de l'ouverture pendant une fraction de la course rotative dudit vantail voisine de sa position d'ouverture totale.Likewise, the door includes elastic means for causing the leaf to rotate in the opening direction. during a fraction of the rotary stroke of said leaf close to its fully open position.

Au-delà d'un certain degré d'ouverture, ces moyens élastiques contribuent à assurer automatiquement l'ouverture complète de la porte.Beyond a certain degree of opening, these elastic means automatically contribute to ensuring the complete opening of the door.

Suivant une réalisation avantageuse de l'invention, l'ensemble des moyens élastiques précités comprend un organe à coulissement longitudinal articulé d'une part en un point du bâti, et d'autre part en un point de l'encadrement de la porte, ces points d'articulation étant disposés de manière à se trouver alignés avec l'axe de rotation du vantail dans une position angulaire intermédiaire de ce dernier.According to an advantageous embodiment of the invention, all of the above-mentioned elastic means comprises a member with longitudinal sliding articulated on the one hand at a point of the frame, and on the other hand at a point of the door frame, these articulation points being arranged so as to be aligned with the axis of rotation of the leaf in an intermediate angular position of the latter.

De préférence, l'organe à coulissement longitudinal est un vérin pneumatique.Preferably, the member with longitudinal sliding is a pneumatic cylinder.

Suivant une réalisation préférée de l'invention, la porte comprend des moyens de verrouillage du bâti sur l'encadrement de la porte, déverrouillables par l'action d'une pression prédéterminée exercée transversalement au vantail.According to a preferred embodiment of the invention, the door comprises means for locking the frame on the frame of the door, unlockable by the action of a predetermined pressure exerted transversely to the leaf.

La porte ne peut donc pas s'ouvrir accidentellement, par exemple sous l'effet d'un courant d'air. Son ouverture nécessite une poussée notable, correspondant à un geste volontaire.The door cannot therefore open accidentally, for example under the effect of a draft. Its opening requires a notable push, corresponding to a voluntary gesture.

Dans le cas où les moyens moteurs du panneau mobile comprennent une vis actionnée par un moteur et coopérant avec un écrou fixé sur ce panneau, l'invention prévoit de disposer un barreau mobile monté sur un mécanisme de verrouillage fixé au bâti, ce mécanisme étant disposé de telle manière que le barreau puisse venir s'engager dans une roue dentée montée en bout de la vis pour bloquer la rotation de cette dernière, ce qui réalise le verrouillage du mouvement coulissant.In the case where the motor means of the movable panel comprise a screw actuated by a motor and cooperating with a nut fixed on this panel, the invention provides for having a movable bar mounted on a locking mechanism fixed to the frame, this mechanism being arranged in such a way that the bar can come to engage in a toothed wheel mounted at the end of the screw to block the rotation of the latter, which realizes the locking of the sliding movement.

Corrélativement, l'invention prévoit encore de disposer un pène pour coopérer avec l'encadrement de la porte, ce qui réalise le verrouillage du mouvement de rotation du bâti.Correspondingly, the invention also provides for having a bolt to cooperate with the door frame, which achieves the locking of the rotational movement of the frame.

Le mécanisme de verrouillage est avantageusement commandé par un électro-aimant alimenté par une batterie autonome, la position de verouillage correspondant au manque de courant. D'autres particularités et avantages de l'invention ressortiront encore de la description détaillée qui va suivre.The locking mechanism is advantageously controlled by an electromagnet powered by an autonomous battery, the locking position corresponding to the lack of current. Other features and advantages of the invention will emerge from the detailed description which follows.

En référence aux Figures 1 et 2, une porte conforme à l'invention comprend un bâti 1 lié à l'encadrement 2 de la porte. Ce bâti porte un panneau fixe 3, lié rigidement au bâti, et un panneau mobile 4 monté sur un chemin de roulement pour coulisser parallèlement au panneau fixe 3, de manière à offrir, en position ouverte, un passage approximativement égal à la moitié de l'encadrement 2.With reference to Figures 1 and 2, a door according to the invention comprises a frame 1 linked to the frame 2 of the door. This frame carries a fixed panel 3, rigidly connected to the frame, and a movable panel 4 mounted on a raceway to slide parallel to the fixed panel 3, so as to offer, in the open position, a passage approximately equal to half the coaching 2.

Le bâti 1 comprend un poteau 5 monté rotatif sur deux paliers 6 et 7, placés à ses deux extrémités.The frame 1 comprises a post 5 rotatably mounted on two bearings 6 and 7, placed at its two ends.

Un moteur électrique 8 actionne une vis sans fin 9 portant un écrou (non représenté sur les Figures 1 et 2) solidaire du panneau mobile 4.An electric motor 8 actuates an endless screw 9 carrying a nut (not shown in Figures 1 and 2) secured to the movable panel 4.

On comprend que la porte peut s'ouvrir non seulement par coulissement du panneau mobile 4, mais également par rotation de l'ensemble des deux panneaux (Figure 2), cette rotation affectant également le bâti 1, de sorte que l'encadrement 2 se trouve alors entièrement dégagé, le moteur 8 étant également entraîné avec la vis 9 dans le mouvement de rotation du bâti 1.It is understood that the door can open not only by sliding of the movable panel 4, but also by rotation of the assembly of the two panels (Figure 2), this rotation also affecting the frame 1, so that the frame 2 is is then completely released, the motor 8 also being driven with the screw 9 in the rotational movement of the frame 1.

On va maintenant décrire cette porte en détail en référence aux Figures 3 à 10.We will now describe this door in detail with reference to Figures 3 to 10.

L'encadrement 2 comporte un linteau 11 formé d'un profilé en U portant une cornière 12. Dans un orifice pratiqué dans l'aile horizontale de cette cornière passe un tourillon 13 solidaire du poteau. 5 pour constituer le palier 6. Le poteau 5 comporte, à sa base, un autre tourillon 14 coopérant avec une plaque d'assise 15 pour constituer le palier 7.The frame 2 comprises a lintel 11 formed of a U-shaped profile carrying an angle 12. In an orifice made in the horizontal wing of this angle passes a pin 13 secured to the post. 5 to constitute the bearing 6. The post 5 comprises, at its base, another journal 14 cooperating with a seat plate 15 to constitute the bearing 7.

Une cornière 16 s'applique d'une part sur le sommet du poteau 5 à section carrée et d'autre part sur l'une de ses faces. A cette cornière est fixé un profilé un U 17 à âme verticale par des boulons 18, 19 (Figure 5). Les boulons 19 qui assemblent l'âme du profilé 17 avec l'aile verticale de la cornière 16 tiennent aussi assemblé un fer plat 21 auquel sont soudés deux tronçons 22 de tube à section rectangulaire. Dans ces tronçons sont logés des écrous 23 qui coopèrent avec des boulons 24 pour tenir une équerre de renforcement 25 et un profilé spécial 26.An angle iron 16 is applied on the one hand to the top of the post 5 of square section and on the other hand to one of its faces. To this angle iron is fixed a U 17 profile with a vertical core by bolts 18, 19 (Figure 5). The bolts 19 which assemble the web of the profile 17 with the vertical wing of the angle iron 16 also hold a flat iron 21 to which two sections 22 of tube with rectangular section are welded. In these sections are housed nuts 23 which cooperate with bolts 24 to hold a reinforcement bracket 25 and a special profile 26.

Alors que le profilé 17 s'étend sur toute la longueur de la porte et constitue la pièce maîtresse du bâti 1 (Figure 3), les profilés spéciaux 26 sont de longueur limitée et répartis sur la longueur du bâti 1, chacun étant renforcé par son équerre 25.While the profile 17 extends over the entire length of the door and constitutes the centerpiece of the frame 1 (Figure 3), the special profiles 26 are of limited length and distributed over the length of the frame 1, each being reinforced by its square 25.

Des boulons 47 (fig. 5) fixent au profilé 26 une bordure 27 fixée au bord supérieur d'un panneau de verre 28 constituant le panneau fixe 3. Ce panneau est muni, à sa base, d'une plinthe en H 29 venant, d'une part, s'encastrer sur lui et, d'autre part, enfourcher un fer carré 31 fixé sur un fer plat 32 lui-même fixé à la base du poteau 5.Bolts 47 (fig. 5) fix to the profile 26 an edge 27 fixed to the upper edge of a glass panel 28 constituting the fixed panel 3. This panel is provided, at its base, with an H-shaped plinth 29, on the one hand, to be embedded on him and, at on the other hand, straddle a square iron 31 fixed on a flat iron 32 itself fixed at the base of the post 5.

Les profilés spéciaux 26 servent de support à une cage à billes 33 s'étendant sur toute la longueur de la porte, et dans lequel coulisse un coulisseau 34 aux extrémités duquel sont fixés deux fers plats 36 (Figures 3 et 9) portant chacun une tige filetée 37. Deux écrous 38 sur cette tige filetée enserrent une aile horizontale d'un profilé 39 formant bordure supérieure d'un panneau de verre 41 constituant le panneau mobile 4.The special profiles 26 serve to support a ball cage 33 extending over the entire length of the door, and in which slides a slide 34 at the ends of which are fixed two flat bars 36 (Figures 3 and 9) each carrying a rod threaded 37. Two nuts 38 on this threaded rod enclose a horizontal wing of a profile 39 forming the upper edge of a glass panel 41 constituting the movable panel 4.

Ce vantail mobile comporte, à sa base, une plinthe 42 (Figure 9) analogue à la plinthe 29 du vantail fixe 3 qui enfourche un profilé rectangulaire 43 en matière plastique sur lequel elle coulisse à frottement doux. Le profilé 43 est fixé sur une cornière 44 fixée sur la plinthe 29 du vantail fixe 3 (Figure 10).This movable leaf comprises, at its base, a plinth 42 (Figure 9) similar to the plinth 29 of the fixed leaf 3 which straddles a rectangular profile 43 of plastic material on which it slides with gentle friction. The section 43 is fixed to an angle iron 44 fixed to the plinth 29 of the fixed leaf 3 (Figure 10).

Il résulte de ce qui vient d'être dit au sujet de la base des vantaux 3 et 4 qu'aucun de ces vantaux n'est en contact avec le sol.It follows from what has just been said about the base of the leaves 3 and 4 that none of these leaves is in contact with the ground.

Le coulisseau 34 porte, dans sa partie médiane, une fourche 45 (Figure 6) qui enserre un écrou à billes 46 coopérant avec une vis sans fin 9. Cette vis est portée par deux paliers 48 (Figure 3) fixés aux profilés spéciaux 26 et accouplée à un moteur électrique 8 par l'intermédiaire d'un manchon 51.The slide 34 carries, in its middle part, a fork 45 (Figure 6) which encloses a ball nut 46 cooperating with an endless screw 9. This screw is carried by two bearings 48 (Figure 3) fixed to the special sections 26 and coupled to an electric motor 8 via a sleeve 51.

Le moteur 8 est fixé par des moyens connus non représentés au profilé spécial 26 et il est doté d'un étage de commande automatique 8a en lui-même connu pour provoquer sa mise en marche automatique dans le sens de l'ouverture ou de la fermeture suivant que, respectivement, une personne ou un véhicule s'approche ou s'éloigne de la porte.The motor 8 is fixed by known means not shown to the special profile 26 and it is provided with an automatic control stage 8a in itself known to cause its automatic starting in the direction of opening or closing. depending on whether, respectively, a person or a vehicle approaches or leaves the door.

Dans l'exemple décrit, il est prévu une programmation de l'étage de commande pour actionner le moteur à une vitesse donnée, relativement grande, sur la plus grande partie de sa course et à une vitesse réduite au voisinage des fins de course du panneau mobile 4, en vue de minimiser les chocs en fin de course. Cette disposition, en elle-méme connue, n'a pas à être décrite ici en détail.In the example described, there is provision for programming the control stage for actuating the motor at a given speed, relatively high, over most of its travel and at a reduced speed in the vicinity of the limit switches of the panel. mobile 4, in order to minimize impact at the end of the stroke. This arrangement, in itself known, need not be described here in detail.

Il résulte de la description qui vient d'être faite jusqu'ici, que l'ensemble constitué par les panneaux 3 et 4 et le bâti 1, peut pivoter autour de l'axe du poteau 5, la porte s'ouvrant par rotation suivant la flèche F (Figures 4, 5, 7, 8).It follows from the description which has just been made so far, that the assembly constituted by the panels 3 and 4 and the frame 1, can pivot around the axis of the post 5, the door opening by following rotation arrow F (Figures 4, 5, 7, 8).

Au voisinage de l'extrémité de la porte opposée au poteau 5, un contacteur 52 est fixé sur le profilé spécial 26 et comporte un bras mobile 53 venant en appui sur une cornière 54 fixée au linteau 11 (Figures 4 et 7). On comprend que, quand la porte est actionnée en rotation, le bras 53 se déplace pour actionner le contacteur 52. Le contacteur est connecté à l'étage de commande programmé du moteur 8 pour provoquer la mise en marche du moteur 8 à vitesse lente dans le sens de l'ouverture dès que la porte amorce un mouvement de rotation dans le sens de l'ouverture.In the vicinity of the end of the door opposite the post 5, a contactor 52 is fixed on the special section 26 and comprises a movable arm 53 bearing on an angle 54 fixed to the lintel 11 (Figures 4 and 7). It is understood that, when the door is actuated in rotation, the arm 53 moves to actuate the contactor 52. The contactor is connected to the programmed control stage of the motor 8 to cause the starting of the motor 8 at slow speed in the opening direction as soon as the door starts a rotational movement in the opening direction.

Une butée 55 en matériau résilient est fixé sur une équerre 56 solidaire du profilé spécial 26 pour prendre appui sur la cornière 54 quand le bâti 1 de la porte est en position de fermeture (Figures 4 et 7).A stop 55 in resilient material is fixed on a bracket 56 integral with the special profile 26 to bear on the angle 54 when the frame 1 of the door is in the closed position (Figures 4 and 7).

Un verrou 57 (Figure 8) comprend une bille prisonnière 58 sollicitée en saillie par un ressort 59 logé dans un boîtier 61 pour coopérer avec un orifice 62 pratiqué dans un profilé 63 solidaire du profilé spécial 26, le boîtier 61 qui retient la bille prisionnière étant lui-même fixé à une cornière 70 solidaire du linteau 11:

  • Un dispositif de verrouillage 64 (Figure 7) comprend un électro-aimant logé dans un boîtier 65 fixé au profilé spécial 26 par l'intermédiaire d'un pied 66. Sur le pied 66 est articulé en 67 un levier 68 relié à un noyau 69 de l'électro-aimant. Ce levier comporte à l'une de ses extrémités un barreau 71 pouvant venir coopérer avec une roue dentée 72 clavetée sur la vis sans fin 9. A l'autre extrémité du levier est articulé un loquet 73 dont le corps 74 est fixé dans un fer plat 75 solidaire du profilé spécial 26.
A latch 57 (Figure 8) comprises a captive ball 58 urged projecting by a spring 59 housed in a housing 61 to cooperate with an orifice 62 formed in a profile 63 integral with the special profile 26, the housing 61 which retains the captive ball itself fixed to an angle 70 secured to the lintel 11:
  • A locking device 64 (Figure 7) comprises an electromagnet housed in a housing 65 fixed to the special profile 26 by means of a foot 66. On the foot 66 is articulated at 67 a lever 68 connected to a core 69 of the electromagnet. This lever comprises at one of its ends a bar 71 which can come to cooperate with a toothed wheel 72 keyed on the worm screw 9. At the other end of the lever is articulated a latch 73 whose body 74 is fixed in an iron flat 75 secured to the special profile 26.

L'électro-aimant est disposé de manière que le noyau 69 soit attiré vers le bras en cas d'excitation et remonte vers le haut, sous l'effet de moyens élastiques non représentés, en cas de manque de courant. Dans la position de manque de courant (Figure 7), le pène 76 est déplacé vers le haut vis-à-vis de la cornière 54 et le barreau 71 est engagé dans la roue dentée 72. En cas d'excitation, ces positions sont inversées, la roue 72 est libérée et le pène 76 est effacé.The electromagnet is arranged so that the core 69 is attracted towards the arm in the event of excitation and rises upwards, under the effect of elastic means not shown, in the event of a lack of current. In the position of lack of current (Figure 7), the bolt 76 is moved upwards towards the angle 54 and the bar 71 is engaged in the toothed wheel 72. In the event of excitation, these positions are reversed, the wheel 72 is released and the bolt 76 is erased.

Dans l'exemple décrit, l'électro-aimant est alimenté par une batterie autonome.In the example described, the electromagnet is powered by an autonomous battery.

A l'extrémité de la porte voisine du poteau 5 est monté un vérin 77 (Figures 3 et 4) dont le corps 78 est articulé en 79 sur la cornière 12 fixée au linteau 11 et dont la tige 81 est articulée en 82 sur un gousset 83 prolongeant la cornière 16 solidaire du poteau 5.At the end of the door next to the post 5 is mounted a jack 77 (Figures 3 and 4) whose body 78 is articulated at 79 on the angle 12 fixed to the lintel 11 and whose rod 81 is articulated at 82 on a gusset 83 extending the angle 16 secured to the post 5.

Les points 79 et 82 sont disposés de manière telle qu'ils se trouvent alignés avec l'axe 98 du poteau 5 dans une position intermédiaire de la porte dans son mouvement de rotation (Figure 11), c'est-à-dire dans la position 77a du vérin, figurée en traits tiretés.The points 79 and 82 are arranged in such a way that they are aligned with the axis 98 of the post 5 in an intermediate position of the door in its rotational movement (Figure 11), that is to say in the position 77a of the jack, shown in dashed lines.

Le vérin 77 travaille constamment à la compression et peut être à ressort, ou, comme dans l'exemple décrit, à air comprimé.The jack 77 works constantly under compression and can be spring loaded, or, as in the example described, compressed air.

Dans la position fermée 3 du panneau fixe, le vérin en position 77 (Figure 11) s'oppose à l'ouverture de la porte, jusqu'à ce que le panneau atteigne la position 3a (en traits tiretés) correspondant à la position 77a du vérin. Au-delà, et jusqu'à la position 3b du panneau (en traits mixtes) d'ouverture complète, correspondant à la position 77b du vérin, le vérin aide à l'ouverture de la porte.In the closed position 3 of the fixed panel, the jack in position 77 (Figure 11) opposes the opening of the door, until the panel reaches position 3a (in dashed lines) corresponding to position 77a cylinder. Beyond, and up to position 3b of the panel (in phantom) full opening, corresponding to position 77b of the jack, the jack helps to open the door.

Enfin, un capot 84 lié au linteau 11 et un capot 85 lié au bâti 1 cachent et protègent les mécanismes décrits. Pour plus de clarté, ces capots ont été supposés enlevés sur les Figures 1 à 4.Finally, a cover 84 linked to the lintel 11 and a cover 85 linked to the frame 1 hide and protect the mechanisms described. For clarity, these covers have been assumed to be removed in Figures 1 to 4.

On va maintenant décrire le fonctionnement de la porte.We will now describe the operation of the door.

A partir de la position de fermeture, telle que représentée sur l'ensemble des Figures (sauf la Figure 2), le fonctionnement normal de la porte consiste dans le coulissement du panneau mobile 4 parallèlement au panneau fixe 3, sous l'effet du moteur 8 actionnant la vis sans fin 9 qui provoque le déplacement translatif de l'écrou 46 et un même déplacement de la fourche 45.From the closed position, as shown in all the Figures (except Figure 2), the normal operation of the door consists in the sliding of the mobile panel 4 parallel to the fixed panel 3, under the effect of the motor 8 actuating the worm screw 9 which causes the translational displacement of the nut 46 and the same displacement of the fork 45.

La mise en marche du moteur 8 peut être provoquée manuellement, par action sur un bouton, ou, comme ici, automatiquement par l'approche d'une personne ou d'un véhicule.The engine 8 can be started manually, by pressing a button, or, as here, automatically by the approach of a person or a vehicle.

Le même mouvement se produit en sens inverse pour l'opération de fermeture.The same movement occurs in reverse for the closing operation.

Dans les deux cas, le panneau mobile se déplace à grande vitesse sur la plus grande partie de sa course et à vitesse lente au voisinage de ses fins de course.In both cases, the movable panel moves at high speed over most of its travel and at slow speed in the vicinity of its limit switches.

En service normal, seul le mouvement coulissant précité est susceptible de se produire, le bâti 1 étant immobilisé en rotation par le verrou à bille 57 qui s'oppose à la rotation des panneaux sous l'effet d'un simple courant d'air ou d'une légère poussée accidentelle.In normal service, only the aforementioned sliding movement is likely to occur, the frame 1 being immobilized in rotation by the ball lock 57 which opposes the rotation of the panels under the effect of a simple draft or a slight accidental push.

Sie la poussée accidentelle en question est relativement forte, elle peut forcer le verrou 57 et laisser la porte s'entr'ouvrir. Mais si l'auteur de la poussée ne persiste pas, la porte se referme sous l'effet du vérin 77 qui s'oppose à l'ouverture.If the accidental thrust in question is relatively strong, it can force the latch 57 and allow the door to open. But if the author of the push does not persist, the door closes under the effect of the jack 77 which opposes the opening.

Si la poussée est à la fois forte et persistante, la porte poursuit son mouvement d'ouverture jusqu'à dépasser la position 77a de compression maximale du vérin et, dès lors, ce vérin aide à l'ouverture de la porte. En même temps, le contacteur 52 provoque le mouvement de coulissement du panneau mobile 4 dans le sens de l'ouverture, à vitesse lente. La vitesse lente permet d'éviter de blesser les personnes qui se pressent contre la porte, tandis que l'ouverture progressive diminue l'espace balayé par les panneaux en rotation et diminue de moitié la prise au vent sur les panneaux quand la rotation est terminée.If the thrust is both strong and persistent, the door continues its opening movement until it exceeds the position 77a of maximum compression of the jack and, consequently, this jack assists in the opening of the door. At the same time, the contactor 52 causes the sliding movement of the movable panel 4 in the direction of opening, at low speed. The slow speed avoids injuring people pressing against the door, while the progressive opening reduces the space swept by the rotating panels and halves the wind resistance on the panels when the rotation is complete .

En position de non-utilisation de la porte, par exemple en fermeture de nuit, l'actionnement du dispositif de verrouillage 64·permet de bloquer les deux mouvements possibles de la porte, en coulissement par la roue dentée 72 et en rotation par le loquet 73. La position de verrouillage correspondant au manque de courant, il y a là un effet anti-vol supplémentaire.In the non-use position of the door, for example at night closing, the actuation of the locking device 64 · makes it possible to block the two possible movements of the door, sliding by the toothed wheel 72 and rotating by the latch 73. The locking position corresponds to the lack of current, there is an additional anti-theft effect.

En utilisation normale, une panne de courant du secteur ne peut pas verrouiller intempestivement la porte puisque l'alimentation de l'électro-aimant est autonome.In normal use, a mains power failure cannot inadvertently lock the door since the power supply to the electromagnet is autonomous.

La porte objet de l'invention présente l'avantage important de dégager entièrement le passage défini par l'encadrement 2, non seulement sur toute la largeur, par effacement des deux panneaux, mais également sur toute la hauteur, par effacement du bâti et du mécanisme qu'il contient (Figure 2).The door object of the invention has the important advantage of completely clearing the passage defined by the frame 2, not only over the entire width, by erasing the two panels, but also over the entire height, by erasing the frame and the mechanism it contains (Figure 2).

Il en résulte qu'en cas de panique d'une foule, le plus large espace est offert à l'évacuation. De même, si l'ouverture en rotation est nécessitée par le passage d'un véhicule tel qu'un camion, le dégagement en hauteur permet le passage de gabarits importants.As a result, in the event of a crowd panic, the widest space is offered for evacuation. Similarly, if the opening in rotation is required by the passage of a vehicle such as a truck, the clearance in height allows the passage of large sizes.

L'utilisation d'une telle porte se justifie d'ailleurs non seulement en vue de la sécurité des personnes en cas de panique, mais également en vue de la préservation de la porte elle-même, si elle vient à être heurtée accidentellement par un véhicule. Le fait qu'elle cède facilement en rotation permet, en effet, d'éviter son endommagement grave.The use of such a door is also justified not only for the safety of people in case of panic, but also for the preservation of the door itself, if it comes into being accidentally struck by a vehicle. The fact that it easily yields in rotation makes it possible to avoid its serious damage.

On notera également que les panneaux ne sont nulle part en appui sur le sol, mais suspendus au bâti. Leur rotation n'implique donc aucun roulement, et ne nécessite donc aucun chemin de roulement pratiqué dans le sol et susceptible de s'encrasser.It will also be noted that the panels are nowhere in abutment on the ground, but suspended from the frame. Their rotation therefore does not involve any rolling, and therefore does not require any raceway made in the ground and liable to clog.

Bien entendu, l'invention ne se limite pas à l'exemple décrit, et l'on pourrait concevoir de nombreuses variantes sans sortir de son cadre. Ainsi, le moteur électrique et le système vis-écrou pourraient être remplacés par un vérin hydraulique ou pneumatique. De même, on pourrait facilement concevoir une porte à quatre panneaux répartis suivant deux vantaux mobiles en rotation, sans modification notable de la réalisation décrite.Of course, the invention is not limited to the example described, and one could conceive of numerous variants without departing from its scope. Thus, the electric motor and the screw-nut system could be replaced by a hydraulic or pneumatic cylinder. Similarly, one could easily design a door with four panels distributed along two movable leaves in rotation, without significant modification of the embodiment described.
