Description

La présente invention concerne un dispositif de commande motorisée pour l'ouverture et la fermeture d'un portail. Il s'agit plus particulièrement, quoique non exclusivement, d'un dispositif destiné à un portail extérieur à deux vantaux pivotants et comprenant, pour actionner chaque vantail, un moteur électrique «tubulaire» monté suivant l'axe de pivotement vertical du vantail et logé dans la partie supérieure d'un élément vertical latéral creux du vantail, le stator du moteur étant solidaire du pivot supérieur du vantail tandis que son rotor est lié en rotation avec l'élément du vantail, par l'intermédiaire d'un réducteur de vitesse et d'un arbre d'entraînement.The present invention relates to a motorized control device for opening and closing a gate. It is more particularly, although not exclusively, a device intended for an external gate with two pivoting leaves and comprising, for actuating each leaf, an “tubular” electric motor mounted along the vertical pivot axis of the leaf and housed in the upper part of a hollow vertical lateral element of the leaf, the motor stator being integral with the upper pivot of the leaf while its rotor is linked in rotation with the element of the leaf, by means of a speed reducer and a drive shaft.

Un dispositif de motorisation de ce genre, pour portail à deux vantaux, est déjà décrit dans le brevet français 2 450 334. L'avantage principal d'un tel dispositif de motorisation est d'être entièrement logé à l'intérieur des éléments du portail qu'il doit actionner, en étant notamment intégré à l'intérieur des montants latéraux des deux vantaux, ces montants ayant une structure tubulaire.A motorization device of this kind, for a portal with two leaves, is already described in French patent 2,450,334. The main advantage of such a motorization device is that it is entirely housed inside the elements of the portal. that it must operate, in particular being integrated inside the lateral uprights of the two leaves, these uprights having a tubular structure.

Dans ce dispositif connu, la commande d'arrêt de chaque moteur, en fin de course du vantail correspondant dans les sens l'ouverture ou de la fermeture, est assurée au moyen d'un limiteur de couple coopérant avec des contacts électriques. De plus, en début d'ouverture ou en fin de fermeture du portail, interviennent des moyens de verrouillage électro-magnétiques permettant de libérer ou d'immobiliser les vantaux par rapport au sol et/ou l'un par rapport à l'autre. Ces moyens de verrouillage situés en dehors de l'axe de pivotement, compliquent la structure du dispositif, et ils nécessitent, pour leur alimentation électrique, le passage de câbles électriques dans les montants et autres éléments des vantaux, ce qui est une solution onéreuse et difficile à mettre en oeuvre notamment dans le cas de la transformation d'un portail manoeuvré manuellement en un portail automatique.In this known device, the stop command for each motor, at the end of the travel of the corresponding leaf in the opening or closing directions, is ensured by means of a torque limiter cooperating with electrical contacts. In addition, at the start of the opening or closing of the gate, electro-magnetic locking means are used to release or immobilize the leaves relative to the ground and / or one relative to the other. These locking means located outside the pivot axis, complicate the structure of the device, and they require, for their electrical supply, the passage of electrical cables in the uprights and other elements of the leaves, which is an expensive solution and difficult to implement in particular in the case of the transformation of a manually operated gate into an automatic gate.

La présente invention vise à éliminer ces inconvénients, en fournissant un dispositif perfectionné de commande motorisée dans lequel le même mécanisme assure pour chaque vantail les fonctions d'entraînement en pivotement dans les deux sens, d'arrêt en fin de course d'ouverture ou de fermeture, et de verrouillage dans les positions extrêmes, ceci dans un but de simplification constructive, de plus grande fiabilité, de sécurité, d'économie et d'adaptation rapide en cas de transformation d'un portail manuel.The present invention aims to eliminate these drawbacks by providing an improved motorized control device in which the same mechanism provides for each leaf the functions of pivoting in both directions, of stopping at the end of the opening stroke or of closing, and locking in extreme positions, with the aim of constructive simplification, greater reliability, security, economy and rapid adaptation in the event of conversion of a manual gate.

A cet effet, l'invention a essentiellement pour objet un dispositif de commande motorisée pour l'ouverture et la fermeture d'un portail, du genre précisé plus haut, dans lequel l'arbre d'entraînement du ou de chaque vantail, arbre dont l'axe coïncide avec l'axe vertical de pivotement du vantail, est accouplé à l'élément du vantail par l'intermédiaire de moyens du genre «came», qui d'une part assurent une liaison en rotation entre l'arbre d'entraînement et le vantail lorsque ce dernier est libre de pivoter autour de l'axe précité, et qui d'autre part sont aptes à provoquer un déplacement vertical limité du vantail, en transformant le mouvement de rotation de l'arbre d'entraînement en un mouvement de translation verticale de l'élément considéré du vantail suivant précité, lorsque cet élément est empêché de pivoter.To this end, the invention essentially relates to a motorized control device for the opening and closing of a gate, of the type specified above, in which the drive shaft of the or each leaf, shaft of which the axis coincides with the vertical pivot axis of the leaf, is coupled to the element of the leaf by means of the “cam” type, which on the one hand ensure a rotational connection between the shaft of drive and the leaf when the latter is free to pivot about the aforementioned axis, and which on the other hand are capable of causing a limited vertical movement of the leaf, by transforming the rotational movement of the drive shaft into a vertical translational movement of the element considered from the aforementioned leaf, when this element is prevented from pivoting.

Les moyens de liaison du genre «came», entre l'arbre d'entraînement et l'élément du vantail, sont constitués, dans une première forme de réalisation de l'invention, d'une part, au moins un galet monté tournant sur un axe horizontal porté par l'arbre d'entraînement, et d'autre part, par au moins une double rampe inclinée formant un «V» inversé et solidaire de l'élément précité du vantail, le ou chaque galet coopérant avec la double rampe inclinée correspondante de manière à provoquer un soulèvement limité du vantail, lorsque ce dernier est empêché de pivoter. Ainsi, lorsque le vantail est libre de pivoter, les galets restent à la pointe supérieure des «V» inversés formés par les doubles rampes, et toute rotation de l'arbre d'entraînement s'accompagne d'une rotation de même valeur des rampes, donc du vantail. Par contre, si le vantail est empêché de pivoter, la rotation de l'arbre d'entraînement, dans un sens ou dans l'autre, provoque la «montée» des rampes inclinées contre lesquelles sont poussés les galets, donc le soulèvement du vantail, par une sorte de liaison helicoïdale.The “cam” type connection means, between the drive shaft and the leaf element, consist, in a first embodiment of the invention, on the one hand, at least one roller mounted rotating on a horizontal axis carried by the drive shaft, and on the other hand, by at least one inclined double ramp forming an inverted "V" and integral with the aforementioned element of the leaf, the or each roller cooperating with the double ramp corresponding inclination so as to cause a limited lifting of the leaf, when the latter is prevented from pivoting. Thus, when the leaf is free to pivot, the rollers remain at the upper point of the inverted "V" formed by the double ramps, and any rotation of the drive shaft is accompanied by a rotation of the same value of the ramps , so the leaf. On the other hand, if the leaf is prevented from pivoting, the rotation of the drive shaft, in one direction or the other, causes the “rise” of the inclined ramps against which the rollers are pushed, therefore the lifting of the leaf , by a sort of helical connection.

Il en résulte que le verrouillage du vantail dans ses positions extrêmes peut être réalisé méchanique- ment, par de simples butées empêchant le pivotement du vantail mais franchissables dans un sens par le vantail lorsque celui-ci est soulevé. Lors de la mise en marche du moteur, le mouvement de rotation de l'arbre d'entraînement est, dans un premier temps, transformé en un soulèvement du vantail qui lui permet d'échapper à la butée de verrouillage. Dans un second temps, le mouvement de rotation de l'arbre d'entraînement, qui se poursuit, imprime au vantail un mouvement de rotation dans le sens de l'ouverture ou de la fermeture. Après franchissement de la butée, le vantail «retombe» en position «basse», et toute sa rotation s'effectue en position «basse», dans la forme de réalisation considérée. Seulement en fin de rotation, donc à l'arrivée en position d'ouverture ou de fermeture complète, le vantail se soulève de nouveau en rencontrant une autre butée, et il retombe finalement dans cette butée.As a result, the leaf can be locked in its extreme positions mechanically, by simple stops preventing the leaf from pivoting but which can be crossed in one direction by the leaf when it is raised. When the motor is started, the rotational movement of the drive shaft is first transformed into a lifting of the leaf which allows it to escape the locking stop. In a second step, the rotation movement of the drive shaft, which continues, gives the leaf a rotational movement in the direction of opening or closing. After crossing the stop, the leaf "falls" in the "low" position, and all of its rotation takes place in the "low" position, in the embodiment considered. Only at the end of rotation, therefore on arrival in the fully open or closed position, the leaf lifts again by meeting another stop, and it finally falls back into this stop.

Dans ce cas, le dispositif comprend encore, avantageusement, un contact électrique de fin de course, provoquant l'arrêt du moteur, qui est disposé de manière à être actionné par un élément du vantail après un soulèvement de ce dernier sur une hauteur prédéterminée. L'arrêt du moteur lorsque le vantail parvient dans une position extrême peut ainsi être automatiquement commandé, simplement en plaçant sur la trajectoire du vantail un butoir dont la hauteur est supérieure à la hauteur prédéterminée mentionnée ci-dessus. Ce butoir constitue pour le vantail un obstacle qui, lorsqu'il est rencontré, provoque le soulèvement du vantail jusqu'à la hauteur pour laquelle le contact de fin de course est actionné. Après coupure de l'alimentation du moteur, le vantail peut revenir de lui-même en position basse, si l'on prévoit un ensemble moto-réducteur «réversible».In this case, the device also advantageously comprises an electrical end-of-travel contact, causing the motor to stop, which is arranged so as to be actuated by an element of the leaf after the latter has been raised to a predetermined height. Stopping the motor when the leaf reaches an extreme position can thus be automatically controlled, simply by placing a stopper on the path of the leaf whose height is greater than the predetermined height mentioned above. This stopper constitutes for the leaf an obstacle which, when encountered, causes the leaf to be raised to the height for which the limit switch is actuated. After switching off the power supply to the motor, the leaf can return by itself to the low position, if a “reversible” motor-reduction unit is provided.

Le poids du vantail assure une certaine pression minimale des doubles rampes inclinées sur les galets correspondants. Pour obtenir le couple d'entraînement désiré, et pouvoir éventuellement ajuster la valeur de ce couple, on prévoit encore des moyens à ressort qui créent une force supplémentaire d'application des doubles rampes inclinées sur les galets. Il peur s'agir d'un ressort mécanique, notamment de type hélicoïdal et coaxial à l'arbre d'entraînement, ou d'un ressort à gaz, formant aussi un amortisseur. Dans ce dernier cas, le ressort à gaz, coaxial à l'arbre d'entraînement, a son extrémité supérieure liée audit arbre, et son extrémité inférieure liée à un tube d'axe vertical, solidaire de la pièce comportant les doubles rampes inclinées.The weight of the leaf ensures a certain minimum pressure of the double ramps inclined on the corresponding rollers. To obtain the driving torque ment desired, and possibly be able to adjust the value of this torque, it also provides spring means which create an additional force of application of the double ramps inclined on the rollers. It may be a mechanical spring, in particular of the helical type and coaxial with the drive shaft, or a gas spring, also forming a shock absorber. In the latter case, the gas spring, coaxial with the drive shaft, has its upper end linked to said shaft, and its lower end linked to a tube with a vertical axis, integral with the part comprising the double inclined ramps.

Dans le cas de la forme de réalisation définie ci-dessus, le fait que la rotation du vantail s'effectue en position «basse» peut être gênant, si le vantail risque de rencontrer des cailloux ou d'autres obstacles présents sur le sol. Cet invonvénient éventuel est évité par une deuxième forme de réalisation, dans laquelle les moyens de liaison du genre «came», entre l'arbre d'entraînement et un élément du vantail, sont constitués, d'une part, par au moins un galet monté tournant sur un axe horizontal porté par l'arbre d'entraînement et, d'autre part, par au moins une double rampe inclinée en forme générale de «V» et solidaire de l'élément précité du vantail, la ou chaque double rampe inclinée étant appliquée sous le galet ou l'un des galets par des moyens à ressort exerçant sur l'élément précité du vantail une force verticale orientée de bas en haut et de valeur supérieure au poids du vantail.In the case of the embodiment defined above, the fact that the leaf is rotated in the "low" position can be troublesome, if the leaf risks encountering stones or other obstacles present on the ground. This possible disadvantage is avoided by a second embodiment, in which the “cam” type connecting means, between the drive shaft and an element of the leaf, consist, on the one hand, of at least one roller. mounted rotating on a horizontal axis carried by the drive shaft and, on the other hand, by at least one double ramp inclined in the general shape of "V" and integral with the aforementioned element of the leaf, the or each double ramp inclined being applied under the roller or one of the rollers by spring means exerting on the aforementioned element of the leaf a vertical force oriented from bottom to top and of value greater than the weight of the leaf.

Ainsi, lorsque le vantail est libre de pivoter, celui-ci est soulevé et maintenu en position «haute» par les moyens à ressort, le ou chaque galet se plaçant à la pointe, donc au point le plus bas de la double rampe inclinée correspondante en «V». Par contre, quand le vantail rencontre un obstacle qui l'empêche de pivoter, le galet a tendance à «monter» sur la rampe, ce qui se traduit par un abaissement de la rampe donc du vantail, l'abaissement s'effectuant à l'encontre de l'action des moyens à ressort. Ainsi, le vantail reste soulevé durant toute sa rotation, de sorte qu'il se situe plus haut par rapport à d'éventuels obstacles présents sur le sol, et en parvenant contre une butée de verrouillage, ce vantail est automatiquement abaissé par l'effet de mouvement relatif du galet et de la rampe. Au moment de la mise en action du dispositif, à partir d'une position d'arrêt sur une butée, l'effet obtenu est inverse: le début de rotation de l'arbre d'entraînement autorise le soulèvement du vantail sous l'action des moyens à ressort, et le vantail qui échappe ainsi à la butée peut amorcer son mouvement de rotation, en restant en position «haute».Thus, when the leaf is free to pivot, it is lifted and kept in the "high" position by spring means, the or each roller being placed at the point, therefore at the lowest point of the corresponding double inclined ramp. in "V". On the other hand, when the leaf encounters an obstacle which prevents it from pivoting, the roller tends to “climb” on the ramp, which results in a lowering of the ramp, therefore of the leaf, the lowering being effected at the against the action of spring means. Thus, the leaf remains raised during its entire rotation, so that it is located higher in relation to possible obstacles present on the ground, and when reaching against a locking stop, this leaf is automatically lowered by the effect. relative movement of the roller and the ramp. When the device is put into action, from a stop position on a stop, the effect obtained is opposite: the start of rotation of the drive shaft allows the leaf to be lifted under the action spring means, and the leaf which thus escapes the stop can initiate its rotational movement, remaining in the "up" position.

Dans le cadre de cette deuxième forme de réalisation, les moyens de liaison du genre «came» comprennent encore avantageusement, de part et d'autre de la ou de chaque double rampe inclinée formant un «V», deux parties secondaires à concavité tournée vers le haut, moins profondes que la partie principale en «V» et séparées de cette dernière par des becs. Grâce à ce profil de came particulier, lorsque le galet «monte» le long de l'une des rampes, il franchit finalement le bec situé au sommet de la rampe pour «retomber» dans l'une des parties secondaires concaves. Le galet et le profil de came sont ainsi immobilisés l'un par rapport à l'autre dans une position relative pour laquelle le vantail est maintenu en position «basse», ce qui assure l'arrêt et le verrouillage (en coopération avec la butée), dans les positions de fermeture et d'ouverture, l'immobilisation du vantail dans la butée de verrouillage se faisant de façon sûre, même en cas de vent.In the context of this second embodiment, the “cam” type connection means still advantageously comprise, on either side of the or each double inclined ramp forming a “V”, two secondary parts with concavity facing towards the top, less deep than the main “V” part and separated from the latter by beaks. Thanks to this particular cam profile, when the roller "rises" along one of the ramps, it finally crosses the spout located at the top of the ramp to "fall back" in one of the concave abutments. The roller and the cam profile are thus immobilized with respect to each other in a relative position for which the leaf is held in the "low" position, which ensures stopping and locking (in cooperation with the stop ), in the closed and open positions, the leaf is immobilized in the locking stop safely, even in the wind.

Dans tous les cas, la ou les doubles rampes inclinées peuvent être formées sur une pièce qui présente un passage central traversé par l'arbre d'entraînement, et qui est liée axialement et en rotation avec l'élément précité du vantail. La pièce pourvue des rampes inclinées peut être directement solidarisée avec l'élément du vantail, tel que montant, ou bien être liée en rotation à cet élément par l'intermédiaire d'un limiteur de couple.In all cases, the inclined double ramp or ramps can be formed on a part which has a central passage through which the drive shaft passes, and which is connected axially and in rotation with the aforementioned element of the leaf. The part provided with inclined ramps can be directly secured to the leaf element, such as an upright, or else be linked in rotation to this element by means of a torque limiter.

Dans cette construction, tous les composants du dispositif sont logés à l'intérieur du vantail plus particulièrement en étant regroupés dans le montant latéral situé du côté le l'axe de pivotement, au-dessous du pivot supérieur. Le principe de fonctionnement exige évidemment que le montage de la partie supérieure du vantail, ainsi que le pivot inférieur, autorisent un mouvement de translation verticale, sur une course de quelques centimètres, pour permettre le soulèvement du vantail.In this construction, all the components of the device are housed inside the leaf, more particularly by being grouped in the lateral upright situated on the side of the pivot axis, below the upper pivot. The operating principle obviously requires that the mounting of the upper part of the leaf, as well as the lower pivot, allow a vertical translational movement, over a stroke of a few centimeters, to allow the leaf to be raised.

En regroupant ainsi tous les composants, et en assurant par un seul mécanisme les fonctions d'entraînement en rotation, de fin de course et de verrouillage, le dispositif de commande motorisée selon l'invention supprime tous les moyens de verrouillage électro-magnétiques placés à distance, ou autres dispositifs de verrouillage indépendants, et par conséquent tout passage de câbles électriques dans les éléments des vantaux.By thus grouping all the components, and by ensuring by a single mechanism the functions of rotary drive, end of travel and locking, the motorized control device according to the invention eliminates all the electromagnetic locking means placed at distance, or other independent locking devices, and consequently any passage of electric cables in the elements of the leaves.

Le mouvement vertical du vantail permet, par ailleurs, de résoudre les problèmes de blocage au sol par l'effet du gel en hiver, ou en raison de petits obstacles présents sur la trajectoire du vantail.The vertical movement of the leaf also makes it possible to solve the problems of blocking on the ground by the effect of frost in winter, or due to small obstacles present in the path of the leaf.

En outre, la rencotre d'un obstacle imprévu et important au cours du mouvement de rotation du vantail provoque automatiquement l'arrêt de ce mouvement, en évitant toute détérioration, et en assurant toute la sécurité souhaitable au cas où l'obstacle serait constitué par une personne ou par un véhicule.In addition, the meeting of an unforeseen and significant obstacle during the leaf rotation movement automatically causes the stop of this movement, avoiding any deterioration, and ensuring all the desirable safety in case the obstacle is constituted by a person or by a vehicle.

La diminution importante du nombre de pièces, par comparaison avec le dispositif existant évoqué en introduction, permet d'augmenter sensiblement la fiabilité du portail motorisé, et cette simplification a aussi pour conséquence une réduction de coût de l'ensemble.The significant reduction in the number of parts, in comparison with the existing device mentioned in the introduction, makes it possible to significantly increase the reliability of the motorized gate, and this simplification also has the consequence of reducing the cost of the assembly.

Enfin, le regroupement de tous les composants nécessaires à la motorisation permet de transformer de façon simple, rapide, et économique un portail à manoeuvre manuelle en un portail automatique. A l'inverse, un portail avec dispositif de commande motorisée selon la présente invention peut être facilement équipé, notamment en ce qui concerne l'aménagement des butées de verrouillage, de manière à être manoeuvrable aussi manuellement, notamment en cas de coupure de l'alimentation électrique.Finally, the regrouping of all the components necessary for the motorization makes it possible to transform in a simple, fast, and economic way a gate with manual operation into an automatic gate. Conversely, a gate with a motorized control device according to the present invention can be easily equipped, in particular with regard to the arrangement of the locking stops, so as to be maneuverable also manually, in particular in the event of power cut. power supply.

De toute façon, l'invention sera mieux comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemples non limitatifs, deux formes d'exécution de ce dispositif de commande motorisée pour l'ouverture et la fermeture d'un portail:

Le portail représenté sur la figure 1 comprend deux vantaux 1 et 2 qui sont montés pivotants, autour d'axes verticaux, par l'intermédiaire de pivots latéraux supérieurs 3 et inférieurs 4, ancrés par exemple dans des poteaux 5 en maçonnerie. Chaque vantail 1 ou 2 possède une ossature rectangulaire formée principalement de deux montants latéraux tubulaires 6 et 7, reliés entre eux par au moins un élément horizontal supérieur 8 et au moins un élément horizontal inférieur 9. Le garnissage intérieur des vantaux 1 et 2 peut être réalisé par un barreaudage 10 et/ou un remplissage 11, suivant toute disposition connue. Dans l'exemple considéré, chaque vantail 1 ou 2 décrit un pivotement d'environ 90°, entre une première position extrême définie par une butée centrale commune 12 qui est la position de fermeture, et une seconde position extrême déterminée par une butée latérale respectivement 13, 14, qui est la position d'ouverture complète (indiquée sommairement par le tracé en traits mixtes), les butées 12, 13 et 14 étant fixées au sol.The portal shown in FIG. 1 comprises two leaves 1 and 2 which are pivotally mounted, around vertical axes, by means of upper lateral 3 and lower 4 pivots, anchored for example in masonry posts 5. Each leaf 1 or 2 has a rectangular frame formed mainly by two tubular lateral uprights 6 and 7, connected together by at least one upper horizontal element 8 and at least one lower horizontal element 9. The interior lining of the leaves 1 and 2 can be produced by a bar 10 and / or a filling 11, according to any known arrangement. In the example considered, each leaf 1 or 2 describes a pivoting of approximately 90 °, between a first extreme position defined by a common central stop 12 which is the closed position, and a second extreme position determined by a lateral stop respectively 13, 14, which is the fully open position (indicated roughly by the dashed line), the stops 12, 13 and 14 being fixed to the ground.

Les deux vantaux 1 et 2 étant équipés de dispositifs de motorisation similaires, on décrira seulement dans la suite le dispositif associé à l'un de ces vantaux, tel que le vantail 1. Plus particulièrement, on décrira d'abord une première forme d'exécution, en référence aux figures 2 à 8.The two leaves 1 and 2 being equipped with similar motorization devices, we will only describe in the following the device associated with one of these leaves, such as the leaf 1. More particularly, we will first describe a first form of execution, with reference to Figures 2 to 8.

La motorisation de l'ouverture et de la fermeture du vantail 1 est assuré par un moto-réducteur électrique «tubulaire» 15, à deux sens de rotation, disposé suivant l'axe de pivotement vertical 16 du vantail 1. Le moto-réducteur 15 est logé dans la partie supérieure de montant latéral 6 du vantail, au-dessous du pivot supérieur 3, le stator du moteur étant rendu solidaire du pivot supérieur 3.The motorization of the opening and closing of the leaf 1 is ensured by an “tubular” electric motor-reducer 15, with two directions of rotation, arranged along the vertical pivot axis 16 of the leaf 1. The motor-reducer 15 is housed in the upper side upright 6 of the leaf, below the upper pivot 3, the stator of the motor being made integral with the upper pivot 3.

Le montant latéral 6 du vantail 1 est monté pivotant autour de l'axe vertical 16, et aussi coulissant suivant cet axe 16, par l'intermédiaire d'au moins deux bagues de guidage 17 et 18 entournant le stator du moto-réducteur 1 5. Ce montage permet un mouvement supplémentaire de translation verticale de l'ensemble du vantail 1, le pivot inférieur 4 étant réalisé de manière à autoriser ce mouvement de translation.The lateral upright 6 of the leaf 1 is pivotally mounted about the vertical axis 16, and also sliding along this axis 16, by means of at least two guide rings 17 and 18 surrounding the stator of the gear motor 1 5 This mounting allows an additional movement of vertical translation of the entire leaf 1, the lower pivot 4 being produced so as to allow this translational movement.

L'arbre de sortie 19 du moto-réducteur 15, constituant l'arbre d'entraînement en rotation du vantail 1, dépasse sous le moto-réducteur 15, suivant l'axe vertical 16. L'arbre d'entraînement 19 est traversé diamétralement par un axe horizontal 20, sur lequel sont montés tournants deux galets opposés 21 et 22, de forme extérieure tronconique.The output shaft 19 of the geared motor 15, constituting the rotary drive shaft of the leaf 1, protrudes under the geared motor 15, along the vertical axis 16. The drive shaft 19 is crossed diametrically by a horizontal axis 20, on which are mounted rotating two opposite rollers 21 and 22, of frustoconical external shape.

A l'intérieur du montant latéral tubulaire 6, et au niveau des galets 21 et 22, est montée une pièce formant came 23, solidarisée avec le montant 6. La pièce 23 présente un passage central 24 traversé par l'arbre d'entraînement 19, et elle comporte surtout deux doubles rampes inclinées 25 et 26, diamétralement opposées. Chaque double rampe 25 ou 26 possède une partie montante et une partie descendante, qui se raccordent à leur partie supérieure de manière à former un «V» inversé, les surfaces de roulement des rampes étant tournées vers le bas. Les deux galets 21 et 22 coopèrent respectivement avec les deux doubles rampes 25 et 26, chaque double rampe prenant appui sur l'un des galets qui peut rouler le long de cette double rampe.Inside the tubular lateral upright 6, and at the level of the rollers 21 and 22, is mounted a piece forming a cam 23, secured to the upright 6. The piece 23 has a central passage 24 crossed by the drive shaft 19 , and it mainly comprises two double inclined ramps 25 and 26, diametrically opposite. Each double ramp 25 or 26 has a rising part and a falling part, which are connected at their upper part so as to form an inverted "V", the running surfaces of the ramps being turned downwards. The two rollers 21 and 22 cooperate respectively with the two double ramps 25 and 26, each double ramp bearing on one of the rollers which can roll along this double ramp.

L'arbre d'entraînement 19 forme, à son extrémité inférieure, une chape à laquelle est liée, par l'intermédiaire d'une goupille 27, l'extrémité supérieure d'un ressort à gaz 28 disposé lui aussi suivant l'axe vertical 16, à l'intérieur du montant latéral 6. La tige 29 du ressort à gaz 28 se termine, à son extrémité inférieure, par un embout 30 qui est lié, par l'intermédiaire d'un petit axe horizontal 31, à l'extrémité inférieure d'un tube 32 d'axe vertical, entourant le ressort à gaz 28. L'extrémité supérieure du tube 32 est rendue solidaire de la pièce formant came 23, donc du montant 6. Le ressort à gaz 28, agissant de haut en bas sur la pièce 23 par l'intermédiaire du tube 32, tend à appliquer les doubles rampes inclinées 25 et 26 contre les galets respectifs 21 et 22, en tirant le montant 6 vers le bas.The drive shaft 19 forms, at its lower end, a yoke to which is linked, by means of a pin 27, the upper end of a gas spring 28 also arranged along the vertical axis 16, inside the lateral upright 6. The rod 29 of the gas spring 28 ends, at its lower end, by a nozzle 30 which is linked, by means of a small horizontal axis 31, to the lower end of a tube 32 with a vertical axis, surrounding the gas spring 28. The upper end of the tube 32 is made integral with the cam part 23, therefore with the upright 6. The gas spring 28, acting from above below on the part 23 via the tube 32, tends to apply the double inclined ramps 25 and 26 against the respective rollers 21 and 22, pulling the upright 6 downwards.

Ainsi, le propre poids du vantail 1 et l'effort supplémentaire créé par le ressort à gaz 28 tendent, normalement, à maintenir les deux galets 21 et 22 dans la région de la pointe des «V» formés par les doubles rampes 25 et 26, comme le montre plus particulièrement la figure 2. Le vantail 1 occupe alors sa position normale basse, également indiquée sur la figure 3. Lorsque le vantail 1 occupe cette position, et qu'il n'est empêché de pivoter par aucun obstacle, le couple de rotation communiqué par le moto-réducteur 15 à l'arbre d'entraînement 19 peut être transmis au vantail 1 par l'intermédiaire de l'axe porte-galets 20, des galets 21 et 22, et de la pièce formant came 23, pour faire pivoter le vantail dans le sens de l'ouverture ou de la fermeture autour de l'axe 16.Thus, the own weight of the leaf 1 and the additional effort created by the gas spring 28 tend, normally, to maintain the two rollers 21 and 22 in the region of the point of the "V" formed by the double ramps 25 and 26 , as shown more particularly in FIG. 2. The leaf 1 then occupies its normal low position, also indicated in FIG. 3. When the leaf 1 occupies this position, and it is not prevented from pivoting by any obstacle, the torque communicated by the geared motor 15 to the drive shaft 19 can be transmitted to the leaf 1 via the roller-bearing axis 20, the rollers 21 and 22, and the cam-forming part 23 , to rotate the leaf in the opening or closing direction around axis 16.

Au contraire, si un obstacle placé volontairement ou involontairement sur le passage du vantail 1 s'oppose au pivotement de ce dernier, la mise en marche du moto-réducteur 15, et la rotation de l'arbre d'entraînement 19 qui en résulte, provoquent la «montée» des rampes inclinées 25 et 26 contre lesquelles sont poussés les galets 21 et 22, comme le montre la figure 4. La pièce formant came 23 est ainsi déplacée vers le haut, suivant la flèche 33, avec le montant latéral 6 et l'ensemble du vantail 1.On the contrary, if an obstacle placed voluntarily or involuntarily on the passage of the leaf 1 opposes the pivoting of the latter, the starting of the geared motor 15, and the rotation of the drive shaft 19 which results therefrom, causes the “inclined” ramps 25 and 26 against which the rollers 21 and 22 are pushed, as shown in FIG. 4. The cam part 23 is thus moved upwards , according to arrow 33, with the lateral upright 6 and the entire leaf 1.

Le moto-réducteur 15 possède un contact électrique de fin de course incorporé 34, qui est actionné par la bague de guidage supérieure 17 du montant 6 si le vantail 1 a été soulevé d'une hauteur prédéterminée h, par exemple égale à 3 centimètres. A l'instant où la bague 17 vient actionner ce contact 34, l'alimentation électrique du moto-réducteur 15 est immédiatement interrompue, de sorte que l'arbre d'entraînement 19 ne communique plus, par l'intermédiaire de l'axe porte-galets 20, le couple de rotation transformé en force de soulèvement par la pièce 23.The gear motor 15 has a built-in electrical limit switch 34, which is actuated by the upper guide ring 17 of the upright 6 if the leaf 1 has been raised from a predetermined height h, for example equal to 3 centimeters. At the moment when the ring 17 actuates this contact 34, the electrical supply to the geared motor 15 is immediately interrupted, so that the drive shaft 19 no longer communicates, via the door shaft. -galets 20, the torque converted into lifting force by the part 23.

A partir de ce moment, le vantail 1 revient de lui-même en position basse, sans décrire aucun pivotement autour de l'axe vertical 16, en raison de la réversibilité du moto-réducteur 15. La descente du vantail 1, à laquelle contribue le ressort à gaz 28, s'accompagne du retour des deux galets 21 et 22 dans la région de la pointe des «V» formés par les doubles rampes inclinées 25 et 26.From this moment, the leaf 1 returns by itself to the low position, without describing any pivoting about the vertical axis 16, due to the reversibility of the gear motor 15. The descent of leaf 1, to which contributes the gas spring 28 is accompanied by the return of the two rollers 21 and 22 in the region of the point of the "V" formed by the double inclined ramps 25 and 26.

Par contre, si le vantail 1 est soulevé seulement d'une hauteur inférieure à la hauteur prédéterminée h, la bague 17 ne vient pas actionner le contact électrique de fin de course 34. Ceci se produit au cas où le vantail 1 rencontre sur son passage un obstacle de hauteur inférieure à la hauteur h; dans un tel cas, après soulèvement du vantail 1 sur une hauteur égale à celle de l'obstacle, le moto-réducteur 15 continue de transmettre un couple de rotation au vantail 1 et ce dernier franchit l'obstacle, après quoi il redescend en position basse et peut encore poursuivre son mouvement de pivotement.On the other hand, if the leaf 1 is raised only from a height less than the predetermined height h, the ring 17 does not actuate the electrical limit switch 34. This occurs in the case where the leaf 1 encounters in its path an obstacle of height less than the height h; in such a case, after lifting the leaf 1 over a height equal to that of the obstacle, the gear motor 15 continues to transmit a torque to the leaf 1 and the latter crosses the obstacle, after which it descends into position low and can still continue its pivoting movement.

Par combinaison des diverses séquences particulières décrites ci-dessus, le fonctionnement d'ensemble du portail s'effectue comme suit, en considérant par exemple le mouvement d'ouverture du vantail 1, à partir de la position de fermeture dans laquelle le vantail est arrêté sur la butée centrale 12:By combining the various specific sequences described above, the overall operation of the gate is carried out as follows, considering for example the opening movement of the leaf 1, from the closed position in which the leaf is stopped on the central stop 12:

La mise en marche du moto-réducteur 15, commandée soit par un bouton-poussoir soit à distance par un émetteur de signaux portatif, provoque tout d'abord le «déverrouillage» du vantail 1, qui se soulève légèrement, de façon à échapper à la butée centrale 12. Le vantail 1 est alors mis en rotation et, après franchissement de la butée 12, il revient dans sa position basse, qu'il conserve normalement durant tout le mouvement de pivotement autour de l'axe vertical 16, jusqu'à l'approche de la butée latérale 13.The starting of the geared motor 15, controlled either by a push button or remotely by a portable signal transmitter, firstly causes the "unlocking" of the leaf 1, which lifts slightly, so as to escape the central stop 12. The leaf 1 is then rotated and, after crossing the stop 12, it returns to its low position, which it normally retains throughout the pivoting movement around the vertical axis 16, until when approaching the lateral stop 13.

Les figures 5 à 8 illustrent, très schématiquement, ce qui se passe lorsque le vantail 1 parvient à la butée latérale 13:Figures 5 to 8 illustrate, very schematically, what happens when the leaf 1 reaches the lateral stop 13:

Cette butée 13 comporte, au-dessus d'une embase 35 fixée au sol, une partie surélevée 36 et un butoir 37, séparés par une partie évidée 38. La partie surélevée 36 possède, par rapport à un plan de référence horizontal, ne hauteur a inférieure à la hauteur de soulèvement h du vantail provoquant l'actionnement du contact électrique de fin de course. Au contraire, le butoir 37 possède une hauteur b supérieure à la hauteur de soulèvement h précitée.This stop 13 comprises, above a base 35 fixed to the ground, a raised part 36 and a stopper 37, separated by a recessed part 38. The raised part 36 has, with respect to a horizontal reference plane, no height a less than the lift height h of the leaf causing the actuation of the electrical limit switch. On the contrary, the stopper 37 has a height b greater than the abovementioned lifting height h.

En atteignant la butée 13, comme le montre la figure 5, la partie inférieure du vantail 1 vient d'abord buter contre le flanc extérieur de la partie surélevée 36. Le vantail 1, empêché de pivoter par l'obstacle que constitue cette partie 36 de la butée 13, décrit un premier déplacement vertical, en se soulevant de la hauteur a.On reaching the stop 13, as shown in FIG. 5, the lower part of the leaf 1 first comes to abut against the external flank of the raised part 36. The leaf 1, prevented from pivoting by the obstacle which this part constitutes 36 of the stop 13, describes a first vertical movement, rising from the height a.

Après avoir été ainsi soulevé, le vantail 1 est de nouveau entraîné en rotation et il franchit entièrement la partie surélevée 36, comme indiqué à la figure 6, puis il «tombe» sur la partie évidée 38, dont la largeur correspond sensiblement à l'épaisseur du vantail 1.After having been thus lifted, the leaf 1 is again driven in rotation and it completely crosses the raised part 36, as shown in FIG. 6, then it "falls" on the hollow part 38, the width of which corresponds substantially to the leaf thickness 1.

Le moto-réducteur continuant de fonctionner et ayant toujours tendance à faire pivoter le vantail 1, ce dernier rencontre alors un nouvel obstacle constitué par le butoir 37. Le vantail 1 est de nouveau soulevé, en glissant contre le flanc du butoir 37, comme montré à la figure 7. Lorsque le vantail 1 s'est déplacé vers le haut sur la hauteur h, le contact de fin de course est actionné et commande immédiatement la mise à l'arrêt du moto-réducteur.The gear motor continuing to operate and always having a tendency to pivot the leaf 1, the latter then encounters a new obstacle constituted by the stopper 37. The leaf 1 is again raised, sliding against the side of the stopper 37, as shown in FIG. 7. When the leaf 1 has moved upwards on the height h, the limit switch is actuated and immediately controls the stopping of the gear motor.

Le vantail 1 «retombe» alors dans la partie évidée 38, et il se trouve finalement immobilisé entre la partie surélevée 36 et le butoir 37 - voir la figure 8.The leaf 1 then "falls back" into the hollowed out part 38, and it is finally immobilized between the raised part 36 and the stopper 37 - see FIG. 8.

Lorsque le moto-réducteur est commandé dans le sens de la fermeture du vantail 1, ce dernier commence par se soulever pour franchir la partie surélevée 36 de la butée 13, puis il «retombe» au-delà de la partie 36 et décrit alors son mouvement de pivotement, jusqu'à ce qu'il parvienne à la butée centrale 12 qui intervient de manière similaire à la butée latérale 13.When the gearmotor is controlled in the direction of closing the leaf 1, the latter begins by lifting to cross the raised part 36 of the stop 13, then it "falls" beyond the part 36 and then describes its pivoting movement, until it reaches the central stop 12 which acts similarly to the lateral stop 13.

Les parties surélevées 36 des butées peuvent être amovibles, pour permettre aussi la manoeuvre du portail en cas de coupure temporaire de l'alimentation électrique des moto-réducteurs.The raised parts 36 of the stops can be removable, to also allow the gate to operate in the event of a temporary cut in the electrical supply to the geared motors.

Le même genre de butées est, bien entendu, utilisable quel que soit l'angle de pivotement des vantaux 1 et 2.The same kind of stops is, of course, usable regardless of the pivot angle of the leaves 1 and 2.

On comprend également qu'un obstacle placé involontairement sur le passage d'un vantail 1 ou 2 intervient de la même manière qu'une butée. Si l'obstacle, tel que caillou, est de faible hauteur, inférieure à la valeur h (toujours par rapport au même plan de référence), il peut être franchi après un léger soulèvement du vantail. Par contre, la présence d'un obstacle plus important, tel qu'une pierre, impose un soulèvement plus important du vantail et provoque l'immobilisation du vantail.It is also understood that an obstacle placed involuntarily on the passage of a leaf 1 or 2 intervenes in the same way as a stop. If the obstacle, such as a pebble, is of low height, less than the value h (always with respect to the same reference plane), it can be cleared after a slight lifting of the leaf. On the other hand, the presence of a larger obstacle, such as a stone, imposes a greater lifting of the leaf and causes the immobilization of the leaf.

Le ressort à gaz 28 assure la descente du vantail 1 ou 2 après chaque franchissement d'obstacle, qu'il s'agisse d'un obstacle placé volontairement (butée) ou involontairement sur le passage du vantail. Ce ressort 28 s'oppose en outre à l'effet que pourrait avoir le vent sur la rotation du vantail 1 ou 2, et il s'oppose aussi à un soulèvement manuel du vantail par une personne mal intentionnée.The gas spring 28 ensures the descent of the leaf 1 or 2 after each obstacle crossing, whether it is an obstacle placed voluntarily (stop) or involuntarily on the passage of the leaf. This spring 28 also opposes the effect that the wind could have on the rotation of the leaf 1 or 2, and it also opposes a manual lifting of the leaf by a malicious person.

A la place du ressort à gaz 28, on peut employer un ressort hélicoïdal ou un autre ressort mécanique remplissant les mêmes fonctions.Instead of the gas spring 28, it is possible to use a helical spring or another mechanical spring fulfilling the same functions.

Les figures 9 à 16 sont relatives à une autre forme d'exécution; sur ces figures, les éléments qui correspondent à ceux précédemment décrits sont désignés par les mêmes repères.Figures 9 to 16 relate to another embodiment; in these figures, the elements which correspond correspond to those previously described are designated by the same references.

Ainsi, la figure 9 montre de nouveau partiellement un vantail 1, comportant du côté de son articulation un montant latéral tubulaire 6, au sommet duquel se raccorde un élément horizontal 8. Le vantail 1 est monté pivotant, autour d'un axe vertical 16, par l'intermédiaire de pivots latéraux, la figure 9 montrant seulement le pivot supérieur 3 ancré dans une partie en maçonnerie 5, telle que poteau.Thus, FIG. 9 again partially shows a leaf 1, comprising on the side of its articulation a tubular lateral upright 6, at the top of which a horizontal element 8 is connected. The leaf 1 is pivotally mounted, around a vertical axis 16, by means of lateral pivots, FIG. 9 showing only the upper pivot 3 anchored in a masonry part 5, such as a post.

Un moto-réducteur électrique «tubulaire» 15, à deux sens de rotation, est disposé suivant l'axe de pivotement vertical 16 du vantail 1. Le moto-réducteur 15 est logé dans la partie supérieure du montant 6, au-dessous du pivot supérieur 3, le stator du moteur étant solidaire de ce pivot 3.A “tubular” electric motor-reducer 15, with two directions of rotation, is arranged along the vertical pivot axis 16 of the leaf 1. The motor-reducer 15 is housed in the upper part of the upright 6, below the pivot upper 3, the stator of the motor being integral with this pivot 3.

Le montant 6 du vantail 1 possède une possibilité de coulissement vertical, suivant l'axe 16, grâce à des bagues de guidage 17 et 18 entourant le stator du moto-réducteur 15. Ce montage coulissant permet un mouvement limité de translation verticale, donc de soulevement et d'abaissement de l'ensemble du vantail 1, le pivot inférieur (non représenté) étant réalisé de manière à ne pas s'opposer à ce mouvement vertical.The upright 6 of the leaf 1 has a possibility of vertical sliding, along the axis 16, thanks to guide rings 17 and 18 surrounding the stator of the geared motor 15. This sliding assembly allows a limited movement of vertical translation, therefore of raising and lowering of the entire leaf 1, the lower pivot (not shown) being produced so as not to oppose this vertical movement.

L'arbre de sortie 19 du moto-réducteur 15, constituant l'arbre d'entraînement en rotation du vantail 1, dépasse sous le moto-réducteur 15, suivant l'axe vertical 16. L'arbre d'entraînement 19 porte un axe horizontal 20, sur lequel est monté tournant un galet 21, pouvant présenter une forme extérieure tronconique.The output shaft 19 of the geared motor 15, constituting the rotary drive shaft of the leaf 1, protrudes under the geared motor 15, along the vertical axis 16. The drive shaft 19 carries an axis horizontal 20, on which is mounted rotating a roller 21, which may have a frustoconical external shape.

A l'intérieur du montant latéral tubulaire 6 est montée une pièce 23 formant came, qui présente un passage central 24 traversé par l'arbre d'entraînement 19. La pièce 23 est liée axialement avec le montant 6, comme indiqué en 39, et elle est aussi liée en rotation avec ce montant 6, par l'intermédiaire d'un limiteur de couple 40.Inside the tubular lateral upright 6 is mounted a part 23 forming a cam, which has a central passage 24 traversed by the drive shaft 19. The part 23 is axially linked with the upright 6, as indicated at 39, and it is also linked in rotation with this upright 6, by means of a torque limiter 40.

Pour former une came, la pièce 23 comporte, au niveau du galet 21, un évidement dont le bord inférieur forme, prinipalement, une double rampe inclinée 25 ayant une allure générale en «V», c'est-à-dire avec deux rampes de rouledment de même pente moyenne a mais d'inclinaisons opposées, l'une étant «montante», et l'autre «descendante» - voir aussi figure 10. Le profil de came comprend encore, de part et d'autre de la double rampe 25 en «V», deux parties secondaires 41, d'allure incurvée et ayant leur concavité tournée vers le haut. Les parties 41 sont moins profondes que la partie principale en «V», et elles sont séparées de cette dernière par des becs 42.To form a cam, the part 23 comprises, at the level of the roller 21, a recess whose lower edge forms, mainly, a double inclined ramp 25 having a general "V" shape, that is to say with two ramps of rolling of the same average slope a but of opposite inclinations, one being "rising", and the other "descending" - see also Figure 10. The cam profile also includes, on either side of the double ramp 25 in "V", two secondary parts 41, curved in appearance and having their concavity turned upwards. The parts 41 are less deep than the main "V" part, and they are separated from the latter by nozzles 42.

Comme le montre la figure 10 la came comprend encore, au-dessus de la double rampe inclinée 25 formant un «V», un bec 43 de forme générale triangulaire et tourné vers le bas, dont les bords sont sensiblement de même pente a que la double rampe inclinée 25.As shown in FIG. 10, the cam also comprises, above the inclined double ramp 25 forming a "V", a beak 43 of generally triangular shape and turned downwards, the edges of which are substantially of the same slope as the double inclined ramp 25.

La figure 10 étant une représentation développée du profil de came, on comprend aisément que les parties apparaissant comme sensiblement rectilignes sur cette figure ont, en réalité, une allure hélicoïdale.FIG. 10 being a developed representation of the cam profile, it is easily understood that the parts appearing to be substantially rectilinear in this figure have, in reality, a helical shape.

L'arbre d'entraînement 19 comporte un prolongement 44 dirigé vers le bas, auquel est lié un disque 45. Un ressort hélicoïdal 28, travaillant en compression et coaxial à l'arbre d'entraînement 19, est appuyé par son extrémité inférieure sur la disque 45, tandis que son extrémité supérieure prend appui sous la pièce 23 formant came, par l'intermédiaire d'une bague 46.The drive shaft 19 has an extension 44 directed downwards, to which a disc 45 is linked. A helical spring 28, working in compression and coaxial with the drive shaft 19, is supported by its lower end on the disc 45, while its upper end bears under the part 23 forming a cam, by means of a ring 46.

Le ressort 28 exerce, sur la pièce 23, une force verticale F orientée de bas en haut, que est transmise au montant 6 du vantail 1 en raison de la liaison axiale (en 39) réalisée entre la pièce 23 et le montant 6. Le ressort 28 est choisi de telle sorte que la valeur de la force F soit supérieure au poids P du vantail 1. Ainsi, le ressort 28 a une double action: d'une part, il applique fortement la double rampe inclinée 25 ou l'une des parties 41 du profil de came sous le galet 21, et d'autre part, il tend à soulever l'ensemble du vantail 1.The spring 28 exerts, on the part 23, a vertical force F oriented from bottom to top, which is transmitted to the upright 6 of the leaf 1 due to the axial connection (at 39) formed between the part 23 and the upright 6. The spring 28 is chosen so that the value of the force F is greater than the weight P of the leaf 1. Thus, the spring 28 has a double action: on the one hand, it strongly applies the double inclined ramp 25 or one parts 41 of the cam profile under the roller 21, and on the other hand, it tends to lift the entire leaf 1.

Le fonctionnement d'ensemble du portail, illustré très schématiquement par les figures 11 à 16 nécessite en outre l'intervention d'une butée de fermeture 12 et d'une butée d'ouverture 13, fixées au sol et coopérant avec la partie inférieure du vantail 1. La butée de fermeture 12 comporte, au-dessus d'une embase 47, un butoir 48 et une partie surélevée 49 séparés par une partie évidée 50. La butée d'ouverture 13 comporte de manière similaire, au-dessus d'une embase 35, une partie surélevée 36 et un butoir 37 séparés par une partie évidée 38.The overall operation of the portal, illustrated very diagrammatically by FIGS. 11 to 16, further requires the intervention of a closing stop 12 and an opening stop 13, fixed to the ground and cooperating with the lower part of the leaf 1. The closing stop 12 comprises, above a base 47, a stop 48 and a raised part 49 separated by a recessed part 50. The opening stop 13 similarly comprises, above a base 35, a raised part 36 and a stopper 37 separated by a recessed part 38.

Le portail étant initialement supposé fermé, le vantail 1 est en position «basse» et repose dans la partie évidée 50 de la butée de fermeture 12, comme le montre la figure 11. Cette position est maintenue par l'introduction du galet 21 dans l'une des parties secondaires concaves 41 du profil de came.The gate being initially assumed to be closed, the leaf 1 is in the “low” position and rests in the hollowed out part 50 of the closing stop 12, as shown in FIG. 11. This position is maintained by the introduction of the roller 21 into the 'one of the concave secondary parts 41 of the cam profile.

Pour commander l'ouverture, le moto-réducteur 15 est mis en marche dans un sens provoquant la mise en rotation de l'arbre d'entraînement 19 selon la flèche 51. Le vantail 1 étant empêché de tourner par la partie surélevée 49, le galet 21 est extrait de la partie secondaire concave 41, franchit le bec voisin 42 et se met à rouler sur la partie «descendante» de la double rampe inclinée en «V» 25. En fait, le galet 21 reste à un niveau constant, et dans le mouvement relatif ainsi créé, c'est le vantail qui se soulève sous l'action du ressort, comme indiqué par la flèche 52 de la figure 12. On note qu'au cours de son soulèvement, le vantail 1 glisse le long du butoir 48.To control the opening, the gear motor 15 is started in a direction causing the rotation of the drive shaft 19 according to arrow 51. The leaf 1 being prevented from rotating by the raised part 49, the roller 21 is extracted from the concave secondary part 41, crosses the neighboring spout 42 and starts rolling on the “descending” part of the double ramp inclined in “V” 25. In fact, the roller 21 remains at a constant level, and in the relative movement thus created, it is the leaf which lifts under the action of the spring, as indicated by the arrow 52 of FIG. 12. It is noted that during its lifting, the leaf 1 slides along stopper 48.

Le mouvement de soulèvement du vantail 1 se poursuit, jusqu'à ce que le galet 21 parvienne au point le plus bas de la double rampe inclinée en «V». A ce moment, comme le montre la figure 13, le bord inférieur du vantail 1 se situe plus haut que la partie surélevée 49 de la butée de fermeture 12.The lifting movement of the leaf 1 continues, until the roller 21 reaches the lowest point of the double ramp inclined in "V". At this time, as shown in FIG. 13, the lower edge of the leaf 1 is located higher than the raised part 49 of the closing stop 12.

L'arbre d'entraînement 19 poursuivant son mouvement de rotation suivant la flèche 51, et le vantail étant désormais libre de pivoter, le mouvement de pivotement du vantail 1 dans le sens de l'ouverture peut véritablement débuter, comme indiqué par une flèche 53 sur la figure 14. Pendant tout le mouvement d'ouverture, le vantail 1 pivote à la même vitesse que l'arbre d'entraînement 19, en restant dans sa position «haute», le galet 21 se maintenant au point le plus bas de la double rampe inclinée 25.The drive shaft 19 continuing its rotational movement along arrow 51, and the leaf being now free to pivot, the pivoting movement of leaf 1 in the direction of opening can actually begin, as indicated by an arrow 53 in FIG. 14. During the entire opening movement, the leaf 1 pivots at the same speed as the drive shaft 19, remaining in its “high” position, the roller 21 remaining at the lowest point of the double inclined ramp 25.

En fin de mouvement d'ouverture, le vantail 1 atteint la butée de fermeture 13 après avoir franchi librement la partie surélevée 36, et il vient d'abord heurter le butoir 37 qui empêche la poursuite de la rotation du vantail. Le mouvement de rotation de l'arbre d'entraînement 19 selon la flèche 51 n'étant pas encore interrompu, le galet 21 va alors rouler sur la partie «montante», de la double rampe inclinée en «V» 25. En fait, le galet 21 restant à un niveau constant, c'est le vantail 1 qui s'abaisse alors, en glissant le long du butoir 37, comme indiqué par une flèche 54 sur la figure 15.At the end of the opening movement, the leaf 1 reaches the closing stop 13 after having crossed the raised part 36 freely, and it first strikes the stopper 37 which prevents the leaf from continuing to rotate. The rotational movement of the drive shaft 19 according to arrow 51 not yet being interrupted, the roller 21 will then roll on the “rising” part, of the double ramp inclined in “V” 25. In fact, the roller 21 remaining at a constant level, it is the leaf 1 which then lowers, by sliding along the stopper 37, as indicated by an arrow 54 in FIG. 15.

Ce mouvement se poursuivant, le bord inférieur du vantail 1 descend dans la partie évidée 38 en parve- nantplus bas que la partie surélevée 36, ce qui assure un début de verrouillage. En fin de «montée» du galet 21, celui-ci franchit l'un des becs 42 et «retombe» dans la partie secondaire concave 41 opposée à celle qu'il avait précédemment quitée - voir figure 16. Le vantail 1 est ainsi arrêté et verrouillé en position d'ouverture. Le moto-réducteur 15 s'arrête automatiquement grâce à une temporisation, le limiteur de couple 40 permettant la rotation de l'arbre 19 et de la pièce 23 alors que le vantail 1 se trouve déjà bloqué.This movement continuing, the lower edge of the leaf 1 descends into the recessed part 38, reaching lower than the raised part 36, which ensures the start of locking. At the end of the "climb" of the roller 21, it crosses one of the spouts 42 and "falls" in the concave secondary part 41 opposite to that which it had previously left - see FIG. 16. The leaf 1 is thus stopped and locked in the open position. The gear motor 15 stops automatically thanks to a time delay, the torque limiter 40 allowing the rotation of the shaft 19 and the part 23 while the leaf 1 is already blocked.

On comprend que le processus exactement inverse se déroule lors de la fermeture du portail, pour laquelle les rôles des deux butées 12 et 13 sont simplement échangés, le vantail décrivant en position «haute» sa rotation l'amenant en position fermée.It is understood that the exactly opposite process takes place during the closing of the gate, for which the roles of the two stops 12 and 13 are simply exchanged, the leaf describing in the "high" position its rotation bringing it into the closed position.

On notera que, au cas où en début de mouvement d'ouverture ou de fermeture le vantail 1 ne se soulèverait pas sous la seule action du ressort 28, par exemple en raison du gel, le galet 21 viendrait coopérer avec le bec 43 du profil de came, pour provoquer positivement le «décollage» du vantail 1.It will be noted that, in the event that at the start of the opening or closing movement the leaf 1 does not lift under the sole action of the spring 28, for example due to frost, the roller 21 would cooperate with the spout 43 of the profile cam, to positively cause leaf "takeoff" 1.

Au lieu d'un seul galet 21, on peut prévoir deux galets diamétralement opposés, coopérant respectivement avec deux profils de came. Il est également possible de supprimer le limiteur de couple 40 associé à un fonctionnement temporisé, et de prévoir, à la place, des contacts électriques de fin de course actionnés par le vantail 1 arrivant en position d'ouverture ou de fermeture.Instead of a single roller 21, two diametrically opposite rollers can be provided, cooperating respectively with two cam profiles. It is also possible to remove the torque limiter 40 associated with a timed operation, and to provide, instead, electrical limit switches actuated by the leaf 1 arriving in the open or closed position.
