Description

L'invention concerne de manière générale les dispositifs d'ouverture et de fermeture d'un battant mobile autour d'un axe, tels que par exemple une porte, ou bien un battant de portail, et plus particulièrement un dispositif comprenant un ensemble mobile en translation dans un plan essentiellement vertical qui porte un élément de roulement et un moteur d'entraînement en rotation de l'élément de roulement autour d'un axe.The invention relates generally to devices for opening and closing a leaf movable around an axis, such as for example a door, or else a gate leaf, and more particularly a device comprising a movable assembly in translation in an essentially vertical plane which carries a rolling element and a motor for driving the rolling element in rotation about an axis.

On connaît déjà de la technique antérieure un dispositif de ce type dans lequel l'ensemble constitué par le moteur et une roulette est solidaire de pattes de guidage munies de douilles à billes. Ces pattes de guidage sont mobiles en translation sur un arbre vertical fixé sur le battant. En outre, dans ce dispositif, la roulette est montée en son centre sur un arbre de sortie du moteur.A device of this type is already known from the prior art in which the assembly constituted by the motor and a roller is integral with guide tabs provided with ball bushings. These guide tabs are movable in translation on a vertical shaft fixed on the leaf. In addition, in this device, the caster is mounted in its center on an output shaft of the engine.

Le dispositif précité présente cependant un certain nombre d'inconvénients.The above device however has a number of drawbacks.

Tout d'abord, en cours de fonctionnement, on remarque que l'adhérence de la roulette sur le sol est très irrégulière. En effet, selon un sens d'avancement du battant, cette adhérence est pratiquement nulle alors qu'elle est trop élevée dans le sens inverse. Lorsque la roulette adhère très fortement au sol, un couple de force s'exerce verticalement sur le battant qui peut alors sortir de ses gonds. Par ailleurs, lorsque l'adhérence de la roulette sur le sol est très faible, le battant avance difficilement.First of all, during operation, we notice that the grip of the caster on the ground is very irregular. Indeed, according to a direction of movement of the leaf, this adhesion is practically zero while it is too high in the opposite direction. When the wheel adheres very strongly to the ground, a force couple is exerted vertically on the leaf which can then come out of its hinges. In addition, when the grip of the caster on the ground is very weak, the leaf hardly advances.

En outre, on observe que la force d'avancement exerçée par le dispositif sur le battant est généralement faible.In addition, it is observed that the advancing force exerted by the device on the leaf is generally low.

En particulier, lorsque la roulette rencontre un obstacle, du type pierre ou bosselage, sur son chemin, une certaine flexion s'applique sur les pattes de guidage à douilles à billes, qui ont tendance à se bloquer en translation. De ce fait, les pattes de guidage ne permettent pas une remontée suffisante du moteur pour que la roulette passe l'obstacle. Ainsi, la roulette reste bloquée sur l'obstacle, le moteur tourne dans le vide et le battant n'avance plus.In particular, when the caster encounters an obstacle, of the stone or embossing type, in its path, a certain bending is applied on the guide tabs with ball bushings, which tend to lock in translation. Therefore, the guide tabs do not allow a sufficient rise of the engine for the wheel to pass the obstacle. Thus, the caster remains blocked on the obstacle, the motor turns in a vacuum and the leaf does not advance any more.

Dans ce dernier cas, la flexibilité du système de guidage se déplaçant sur l'arbre vertical et l'adhérence trop faible de la roulette sur le sol sont deux inconvénients qui se cumulent.In the latter case, the flexibility of the guidance system moving on the vertical shaft and the too weak grip of the caster on the ground are two disadvantages which are cumulative.

Afin de pallier ces inconvénients, on recommande alors généralement d'utiliser ce dispositif en association avec un chemin de roulement parfaitement dégagé sur lequel la roulette peut se déplacer sans risque de rencontrer un obstacle quelconque, ce qui entraîne des coûts supplémentaires de réalisation. Enfin, pour obtenir une adhérence plus régulière de la roulette sur le sol, le dispositif précité comporte un système de compensation du type vérin ou équivalent qui exerce une force de compensation sur le moteur, cette force étant positive ou négative afin d'augmenter ou de diminuer l'adhérence de la roulette sur le sol. Ce système de compensation n'est pas simple et augmente le coût de réalisation du dispositif.In order to overcome these drawbacks, it is generally recommended to use this device in combination with a perfectly clear raceway on which the caster can move without the risk of encountering any obstacle, which leads to additional production costs. Finally, to obtain a more regular grip of the caster on the ground, the aforementioned device comprises a compensation system of the jack or equivalent type which exerts a compensating force on the motor, this force being positive or negative in order to increase or decrease the grip of the caster on the ground. This compensation system is not simple and increases the cost of producing the device.

La présente invention vise à pallier les inconvénients précités en proposant un nouveau dispositif d'ouverture et de fermeture tel que décrit dans la revendication 1.The present invention aims to overcome the aforementioned drawbacks by proposing a new opening and closing device as described in claim 1.

Des aspects préférés de l'invention sont explicités dans les sous-revendications.Preferred aspects of the invention are explained in the dependent claims.

La description qui va suivre, en regard des dessins annexés donnés à titre d'exemples non limitatifs fera bien comprendre en quoi consiste l'invention et comment elle peut être réalisée.The description which follows, with reference to the appended drawings given by way of nonlimiting examples will make it clear what the invention consists of and how it can be implemented.

La figure 1 est une vue schématique en perspective du dispositif selon l'invention.Figure 1 is a schematic perspective view of the device according to the invention.

La figure 2 est une vue de face du dispositif de la figure 1.Figure 2 is a front view of the device of Figure 1.

La figure 3 est une vue de côté du dispositif de la figure 1 en mouvement.Figure 3 is a side view of the device of Figure 1 in motion.

La figure 4 est une vue de côté d'une variante de réalisation du dispositif de la figure 3.FIG. 4 is a side view of an alternative embodiment of the device of FIG. 3.

En référence tout d'abord aux figures 1 et 2, on a représenté un dispositif d'ouverture et de fermeture d'un battant mobile autour d'un axe vertical.Referring firstly to Figures 1 and 2, there is shown a device for opening and closing a movable leaf around a vertical axis.

Ce dispositif comporte un élément de roulement, ici une roulette à pneumatique 10 présentant un diamètre d'environ 100mm. Cette roulette est montée à rotation de façon excentrique sur un arbre d'entraînement d horizontal, relié à un pignon d'entraînement 11. Ce pignon d'entraînement 11 coopère avec un pignon 21 monté à rotation sur un arbre de rotation de sortie d'un moteur 20. L'excentrique entre l'arbre d'entraînement en rotation d et l'axe central de la roulette 10 est ici de l'ordre de 10mm.This device comprises a rolling element, here a pneumatic caster 10 having a diameter of approximately 100mm. This roller is rotatably mounted eccentrically on one of horizontal drive shaft connected to a drive gear 11. This drive gear 11 cooperates with a pinion 21 rotatably mounted on an output rotary shaft a motor 20. The eccentric between the rotational drive shaft d and the central axis of the caster 10 is here of the order of 10mm.

Selon une variante de réalisation, on peut envisager un élément de roulement de forme ovoïde entraîné en rotation autour d'un axe de sorte que la distance entre l'axe de rotation et la surface de contact de l'élément de roulement avec le sol varie.According to an alternative embodiment, it is possible to envisage an ovoid-shaped rolling element driven in rotation about an axis so that the distance between the axis of rotation and the contact surface of the rolling element with the ground varies. .

En outre, on distingue sur les figures 1 et 2 un châssis 30 qui comporte deux tiges 31, 32 parallèles raccordées entre-elles à chacune de leurs extrémités par deux parties transversales inférieure et supérieure 33, 34. Les deux tiges 31, 32 du châssis 30 sont emprisonnées en translation essentiellement dans un plan vertical respectivement entre deux ensembles de galets 41, 42, 43, 44, 41', 42', 43', 44' montés à rotation libre sur des parties 52, 53 solidaires du battant ici non représenté. Selon la direction longitudinale des tiges, la partie inférieure transversale 33 du châssis 30 se situe en dessous des galets et la partie supérieure transversale 34 du châssis se trouve au-dessus desdits galets. Le moteur 20 est alors solidaire d'un support 22 fixé sur la partie inférieure transversale 33 du châssis 30. Ainsi, le châssis 30 porte le moteur 20 et permet de déplacer ce dernier en translation verticale.In addition, there are in FIGS. 1 and 2 a chassis 30 which comprises two parallel rods 31, 32 connected to each other at each of their ends by two lower and upper transverse parts 33, 34. The two rods 31, 32 of the chassis 30 are trapped in translation essentially in a vertical plane respectively between two sets of rollers 41, 42, 43, 44, 41 ', 42', 43 ', 44' mounted with free rotation on parts 52, 53 integral with the leaf here not represented. In the longitudinal direction of the rods, the lower transverse part 33 of the chassis 30 is located below the rollers and the upper transverse part 34 of the chassis is located above said rollers. The motor 20 is then secured to a support 22 fixed on the lower transverse part 33 of the chassis 30. Thus, the chassis 30 carries the motor 20 and makes it possible to move the latter in vertical translation.

Plus particulièrement, on distingue sur la figure 1, un bâti 50 comprenant un premier panneau vertical 51 destiné à être fixé sur le battant non représenté. Ce premier panneau 51 comporte à chacun de ses bords verticaux deux parois 52, 53 qui s'étendent à partir desdits bords verticaux du panneau 51 essentiellement perpendiculairement à ce dernier. Ces deux parois 52, 53 présentent des faces intérieures en regard l'une de l'autre. Deux ensembles de galets 41, 42, 43, 44, 41', 42', 43', 44' sont montés respectivement sur les faces intérieures en regard desdites parois 52, 53. Chaque ensemble de galets comporte deux paires de galets montées à rotation libre sur chacune desdites parois 52, 53. Chaque paire de galets 41, 42, 43, 44 est montée en vis-à-vis de part et d'autre de chaque tige 31, 32 du châssis 30. Les deux paires de galets d'un même ensemble sont disposées à distance l'une de l'autre suivant l'axe longitudinal de chaque tige 31, 32 pour former un guidage de chaque tige 31, 32 en translation. Bien entendu, les deux ensembles de galets 41, 42, 43, 44, 41', 42', 43', 44' sont montés au même niveau de telle sorte que chaque paire de galets montée sur une paroi se trouve en regard d'une autre paire de galets montée sur l'autre paroi. Chaque galet 41, 42, 43, 44, 41', 42', 43', 44' présente ici une forme essentiellement cylindrique de révolution avec un axe central de rotation et est muni sur sa surface périphérique cylindrique d'une gorge annulaire 43a, 44a, 43'a, 44'a de section en V. Les galets sont réalisés par exemple en matière plastique rigide.More particularly, there is a distinction in FIG. 1, a frame 50 comprising a first vertical panel 51 intended to be fixed to the leaf, not shown. This first panel 51 has at each of its vertical edges two walls 52, 53 which extend from said vertical edges of the panel 51 essentially perpendicular to the latter. These two walls 52, 53 have interior faces facing each other. Two sets of rollers 41, 42, 43, 44, 41 ', 42', 43 ', 44' are mounted respectively on the interior faces opposite said walls 52, 53. Each set of rollers comprises two pairs of rollers mounted for rotation free on each of said walls 52, 53. Each pair of rollers 41, 42, 43, 44 is mounted opposite each side of each rod 31, 32 of the frame 30. The two pairs of rollers d 'the same set are arranged at a distance from each other along the longitudinal axis of each rod 31, 32 to form a guide for each rod 31, 32 in translation. Of course, the two sets of rollers 41, 42, 43, 44, 41 ', 42', 43 ', 44' are mounted at the same level so that each pair of rollers mounted on a wall is opposite another pair of rollers mounted on the other wall. Each roller 41, 42, 43, 44, 41 ', 42', 43 ', 44' has here an essentially cylindrical shape of revolution with a central axis of rotation and is provided on its peripheral surface cylindrical with an annular groove 43a, 44a, 43'a, 44'a of V section. The rollers are made for example of rigid plastic.

On notera que suivant le mode de réalisation de la figure 1 et 2, les tiges 31, 32 sont dirigées suivant des axes parallèles essentiellement obliques par rapport au panneau 51 du bâti monté verticalement sur le battant non représenté. Ces tiges 31, 32 se déplacent en translation entre les galets dans les gorges en V de ces derniers. Le déplacement de ces tiges se fait dans la direction longitudinale des tiges suivant une direction essentiellement oblique. En outre, l'axe de rotation d de la roulette 10 est ici sécant à la direction de translation desdites tiges 31, 32 et est essentiellement perpendiculaire à cette dernière.It will be noted that according to the embodiment of Figure 1 and 2, the rods 31, 32 are directed along parallel axes essentially oblique to the panel 51 of the frame mounted vertically on the leaf not shown. These rods 31, 32 move in translation between the rollers in the V-shaped grooves of the latter. The displacement of these rods takes place in the longitudinal direction of the rods in an essentially oblique direction. In addition, the axis of rotation d of the caster 10 here intersects the direction of translation of said rods 31, 32 and is essentially perpendicular to the latter.

Suivant une variante de réalisation plus particulièrement représentée sur la figure 4, les tiges 31, 32 sont disposées d'une façon parallèle par rapport au panneau 51 et donc au battant non représenté. Suivant ce mode de réalisation, les galets sont disposés en vis-à-vis de part et d'autre des tiges selon l'axe longitudinal desdites tiges. Selon cette variante, l'axe de rotation d de la roulette 10 est décalé par rapport à la direction de translation desdites tiges 31, 32.According to an alternative embodiment more particularly shown in Figure 4, the rods 31, 32 are arranged in a parallel manner relative to the panel 51 and therefore to the leaf not shown. According to this embodiment, the rollers are arranged opposite each other of the rods along the longitudinal axis of said rods. According to this variant, the axis of rotation d of the caster 10 is offset relative to the direction of translation of said rods 31, 32.

On remarquera sur la figure 2 que le dispositif comporte sur l'axe d de rotation de la roulette 10 un limiteur de couple constitué d'une part, par deux rondelles 12, 13 FERRODO (marque déposée) disposées de part et d'autre du flasque de la roulette 10, une première rondelle 12 étant placée entre la roulette et les pignons d'entraînement 11, 21 et une deuxième rondelle 13 étant placée de l'autre côté du flasque et d'autre part, par deux rondelles de Belleville 14,15 et un écrou de serrage 16 disposé au bout de l'axe d du côté opposé au moteur. Les rondelles de Belleville 14, 15 sont placées entre la deuxième rondelle FERRODO (marque déposée) 13 et l'écrou de serrage 16. Ainsi, lorsque le battant arrive en fin de course, le limiteur de couple évite à la roulette de patiner car la pression exerçée sur les rondelles FERRODO (marque déposée) est inférieure à la pression exerçée par la roulette sur le sol.It will be noted in FIG. 2 that the device comprises on the axis d of rotation of the caster 10 a torque limiter constituted on the one hand, by two washers 12, 13 FERRODO (registered trademark) arranged on either side of the flange of the caster 10, a first washer 12 being placed between the caster and the drive pinions 11, 21 and a second washer 13 being placed on the other side of the flange and on the other hand, by two Belleville washers 14 , 15 and a clamping nut 16 disposed at the end of the axis d on the side opposite the motor. The Belleville washers 14, 15 are placed between the second FERRODO (registered trademark) washer 13 and the clamping nut 16. Thus, when the wing reaches the end of its travel, the torque limiter prevents the roller from slipping because the the pressure exerted on the FERRODO washers (registered trademark) is less than the pressure exerted by the caster on the ground.

Par ailleurs, suivant le mode de réalisation des figures 1 et 2, l'ensemble moteur 20 et roulette 10 est disposé à l'intérieur du châssis 30 c'est-à-dire entre le panneau 51 du bâti et les tiges 31, 32. Ceci permet d'obtenir un gain de place et de constituer un dispositif moins encombrant.Furthermore, according to the embodiment of FIGS. 1 and 2, the motor 20 and caster 10 assembly is disposed inside the chassis 30, that is to say between the panel 51 of the frame and the rods 31, 32 This makes it possible to save space and to constitute a less bulky device.

Suivant un autre mode de réalisation, comme plus particulièrement représenté sur la figure 4, on peut envisager que l'ensemble constitué par le moteur 20 et la roulette 10 est disposé à l'extérieur du châssis 30.According to another embodiment, as more particularly shown in FIG. 4, it can be envisaged that the assembly constituted by the motor 20 and the caster 10 is arranged outside the chassis 30.

En outre, il convient de noter que la roulette est légèrement inclinée par rapport au plan de translation vertical du châssis 30, de sorte que l'axe de pivotement de la roulette passe au proche voisiange de l'axe de pivotement du battant, afin d'éviter un dérapage de celle-ci lorsque le dispositif est en fonctionnement pour l'ouverture ou la fermeture du battant. En effet, lorsque le battant pivote autour de son axe de pivotement, tout point situé sur le battant décrit une portion de cercle présentant un rayon plus ou moins grand en fonction de la distance du point à l'axe de pivotement. La roulette étant située en dehors du battant à un certain niveau, l'angle d'inclinaison de la roulette 10 par rapport au châssis 30 est alors ajusté de manière que la roulette suive la portion de cercle décrit par les points du battant situés au même niveau afin d'éviter tout dérapage.In addition, it should be noted that the caster is slightly inclined relative to the vertical translation plane of the chassis 30, so that the pivot axis of the caster passes close to the pivot axis of the leaf, in order to '' avoid slipping of the latter when the device is in operation for opening or closing the leaf. In fact, when the leaf pivots about its pivot axis, any point located on the leaf describes a portion of a circle having a greater or lesser radius as a function of the distance from the point to the pivot axis. The caster being located outside the leaf at a certain level, the angle of inclination of the caster 10 relative to the frame 30 is then adjusted so that the caster follows the portion of the circle described by the points of the casing situated at the same level to avoid any skidding.

En référence aux figures 3 et 4, nous allons maintenant décrire le fonctionnement du dispositif selon l'invention monté sur un battant de portail par exemple.Referring to Figures 3 and 4, we will now describe the operation of the device according to the invention mounted on a gate leaf for example.

Il convient de noter que d'une manière générale le sol sur lequel est monté un battant de portail présente généralement une certaine pente afin de faciliter l'ouverture et la fermeture dudit battant.It should be noted that in general the ground on which a gate leaf is mounted generally has a certain slope in order to facilitate the opening and closing of said leaf.

Sur les figures 3 et 4, on distingue deux variantes de réalisation du dispositif selon l'invention représentées à deux positions différentes du battant, et plus particulièrement à la position ouverte et à la position fermée.In Figures 3 and 4, there are two alternative embodiments of the device according to the invention shown in two different positions of the leaf, and more particularly in the open position and the closed position.

Lorsque le battant est ouvert, ici l'ensemble mobile du dispositif se trouve en position basse A, position dans laquelle la partie transversale supérieure 34 du châssis 30 est positionnée juste au-dessus des galets 41, 42, 43, 44, à proximité de ces derniers. Dans cette position, on remarquera que le moteur 20 et la roulette 10 se trouvent en dessous des ensembles de galets.When the leaf is open, here the mobile assembly of the device is in the low position A , position in which the upper transverse part 34 of the frame 30 is positioned just above the rollers 41, 42, 43, 44, near these latter. In this position, it will be noted that the motor 20 and the caster 10 are located below the sets of rollers.

Pour fermer le battant, le moteur en fonctionnement entraîne la roulette qui roule sur le sol incliné en poussant le battant ouvert vers sa position fermée. Entre la position ouverte et la position fermée l'ensemble mobile remonte, les tiges 31, 32 du châssis se translatant verticalement entre les galets de manière à positionner ledit ensemble en position haute B lorsque le battant est fermé. Dans cette position haute B, on remarque que la partie transversale inférieure 33 du châssis 30 se trouve juste en dessous des galets 41, 42, 43, 44, à proximité de ces derniers, et l'ensemble constitué par le moteur 20 et la roulette 10 se trouve au niveau desdits galets. Il convient de noter que d'une manière avantageuse, lorsque la roulette rencontre un obstacle sur son chemin, la flexion s'exerce sur la tige et non pas sur les galets. La tige fléchie légèrement se translate tout de même correctement entre les galets en rotation libre, ce qui permet de soulever le moteur suffisamment pour que la roulette passe l'obstacle. On a alors aucunement besoin d'un chemin de roulement pour la roulette. En outre, la roulette tournant de façon excentrique sur le sol, a tendance à chaque tour à faire remonter le moteur. Le poids du moteur s'opposant à cette remontée produit l'effet inverse en contribuant au maintien de la roulette sur le sol. De plus, il est intéressant de souligner que le montage excentrique de la roulette permet, pour un couple moteur donné, d'obtenir à chaque tour, lorsque la distance entre l'axe de rotation de la roulette et son point de contact avec le sol est la plus faible, une force maximale d'appui. On améliore ainsi l'adhérence de la roulette sur le sol pentu ou non quel que soit le sens d'avancement du dispositif et du battant.To close the leaf, the motor in operation drives the caster which rolls on the inclined ground by pushing the open leaf towards its closed position. Between the open position and the closed position, the movable assembly rises, the rods 31, 32 of the chassis translating vertically between the rollers so as to position said assembly in the high position B when the leaf is closed. In this high position B , we notice that the lower transverse part 33 of the chassis 30 is located just below the rollers 41, 42, 43, 44, close to the latter, and the assembly formed by the motor 20 and the roller 10 is located at said rollers. It should be noted that, advantageously, when the roller encounters an obstacle in its path, the bending is exerted on the rod and not on the rollers. The slightly bent rod still translates correctly between the freely rotating rollers, which allows the motor to be raised enough for the roller to pass the obstacle. There is then no need for a raceway for the wheel. In addition, the caster rotating eccentrically on the ground, tends to turn the engine every turn. The weight of the motor opposing this rise produces the opposite effect by helping to keep the caster on the ground. In addition, it is interesting to emphasize that the eccentric mounting of the caster makes it possible, for a given engine torque, to obtain at each revolution, when the distance between the axis of rotation of the caster and its point of contact with the ground is the weakest, maximum support force. This improves the grip of the caster on the slope or not, whatever the direction of travel of the device and the leaf.

On observera que l'on peut utiliser la roulette montée à rotation de manière excentrique avec d'autres systèmes de guidage/translation que celui décrit dans la présente description.It will be observed that the caster mounted for rotation eccentrically can be used with other guidance / translation systems than that described in the present description.

Par ailleurs, il est intéressant de noter que le moteur du dispositif présente ici une puissance de l'ordre de 20 Watts et la force obtenue au bout du battant, pour un poids total du dispositif de l'ordre d'un kilo, est de l'ordre de 6 à 14 kilos.Furthermore, it is interesting to note that the motor of the device here has a power of the order of 20 Watts and the force obtained at the end of the leaf, for a total weight of the device of the order of one kilo, is around 6 to 14 kilos.
