Abstract

A compact automatic stop device for two mechanisms for counting revolutions which consist of coaxial counting wheels (10, 10') each associated with a notched cam (14, 14') interacts with a cutoff finger (24, 24') securely fastened to a common cutoff lever (20, 20'), so that when the notches (19) are aligned, the cutoff lever actuates a switch (26, 26'). A set-to-zero lever (29, 29') makes it possible to reset the counting wheels to zero by acting via hammers (33') on core cams (18'). The counting wheels, the cutoff levers and the set-to-zero levers of each counting mechanism are pivoted in a common cradle (5, 5') articulated with respect to a fixed casing (1) having profiled parts (36, 37, 36', 37') which are intended to interact with the cutoff levers and the set-to-zero levers during the displacement of the cradles.

Description

La présente invention a pour objet un dispositif d'arrêt automatique pour l'entraînement motorisé électrique de porte, volet, store ou similaire, comprenant deux mécanismes de comptage de tours, constitués de roues coaxiales entraînées à des vitesses différentes et associées chacune à une came à encoche coopérant avec un doigt de coupure solidaire d'un levier de coupure commun sollicité par un ressort maintenant les doigts de coupure en appui contre les roues à encoche de telle manière que lorsque les encoches sont alignées, les doigts de coupure pénètrent dans les encoches et un interrupteur est actionné par le levier de coupure, le dispositif comprenant en outre deux mécanismes de mise à zéro des mécanismes de comptage constitués essentiellement de moyens de débrayage des roues de comptage et d'un levier de mise à zéro munis de marteaux agissant sur des cames coeur associées respectivement à chacune des roues du mécanisme de comptage.The present invention relates to an automatic stop device for the electric motorized drive of a door, shutter, blind or the like, comprising two revolution counting mechanisms, consisting of coaxial wheels driven at different speeds and each associated with a cam with a notch cooperating with a cutting finger integral with a common cutting lever biased by a spring holding the cutting fingers in abutment against the notched wheels so that when the notches are aligned, the cutting fingers penetrate into the notches and a switch is actuated by the cut-off lever, the device further comprising two mechanisms for zeroing counting mechanisms consisting essentially of disengaging means of the counting wheels and of a zeroing lever provided with hammers acting on heart cams associated respectively with each of the wheels of the counting mechanism.

Un tel dispositif est connu du brevet FR 2 455 695 à la différence toutefois que ce dispositif antérieur ne comporte qu'un seul mécanisme de comptage. Dans ce dispositif, le mouvement différentiel des roues de comptage est obtenu par une liaison cinématique réalisée au moyen d'un élément de renvoi à engrènement intermitent pivoté sur un axe parallèle aux roues de comptage. Ce type d'engrènement permet de compter un grand nombre de tours avec une bonne précision, mais présente des inconvénients lorsqu'il s'agit de réaliser un dispositif assurant deux points d'arrêt automatique comme ceci est généralement nécessaire dans le cas d'un store ou d'un volet roulant. En effet, pour entraîner deux mécanismes de comptage, il est nécessaire d'avoir deux renvois indépendants qui doivent être pivotés soit sur deux axes différents eux-mêmes différents de l'axe supportant l'entrée du mouvement sur la première roue, soit sur un même axe mais les renvois étant alors disposés dans le prolongement l'un de l'autre. En outre, un engrènement intermittent nécessite des aménagements d'accompagnement comme celui de la présence d'un ressort de maintien en position pendant la période de non engrènement. Tout ceci est source d'encombrement important, de complications et donc de surcoût. En outre, dans le dispositif antérieur, les moyens de débrayage et de mise à zéro des roues de comptage sont relativement compliqués et les roues de comptage sont montées sur un berceau pivotant sur le bâti alors que le levier de coupure est monté directement sur le bâti. Ceci allonge la chaîne des tolérances et nécessite le respect d'une grande précision sur les constituants élémentaires du dispositif.Such a device is known from patent FR 2 455 695 with the difference, however, that this prior device only comprises a single counting mechanism. In this device, the differential movement of the counting wheels is obtained by a kinematic connection produced by means of a return element with intermittent meshing pivoted on an axis parallel to the counting wheels. This type of meshing makes it possible to count a large number of turns with good precision, but has drawbacks when it comes to making a device ensuring two automatic stopping points as this is generally necessary in the case of a blind or roller shutter. Indeed, to drive two mechanisms counting, it is necessary to have two independent references which must be pivoted either on two different axes themselves different from the axis supporting the entry of the movement on the first wheel, or on the same axis but the references being then arranged in the extension of one another. In addition, an intermittent meshing requires accompanying arrangements such as that of the presence of a holding spring in position during the non-meshing period. All this is a source of significant bulk, complications and therefore additional cost. In addition, in the prior device, the means for disengaging and zeroing the counting wheels are relatively complicated and the counting wheels are mounted on a cradle pivoting on the frame while the cut-off lever is mounted directly on the frame. . This lengthens the chain of tolerances and requires compliance with great precision on the elementary components of the device.

Du brevet US 4 171 473, on connaît également un mécanisme de comptage comportant trois roues de comptage disposées coaxialement et dans lequel chaque roue de comptage engrène avec un pignon distinct, les pignons étant disposés sur un même axe avec lequel ils sont solidaires en rotation. Le mouvement différentiel des roues de comptage est obtenu grâce à un rapport différent entre chaque couple de roue et pignon. Chaque roue comporte des zones de glissement et des encoches coopérant avec des galets ayant la fonction de leviers de coupure. Ce dispositif est complexe et nécessite un axe de pignon par mécanisme de comptage, un pignon par roue de comptage et une liaison cinématique entre chaque axe de comptage et l'axe d'entrée du mouvement. En outre, la remise en position de début de comptage n'est pas aisée, ni très rapide car il est nécessaire, après avoir amené la porte, volet roulant ou similaire dans la position d'arrêt souhaitée, d'agir axialement sur une molette pour débrayer l'axe de pignon de l'axe d'entrée, puis l'entraîner manuellement en rotation jusqu'à ce que les roues de comptage du mécanisme de comptage prennent la position permettant à tous les galets du mécanisme de coupure de pénétrer simultanément dans les encoches des roues de comptage. Si les roues de comptage sont dans une position quelconque, l'opération peut prendre beaucoup de temps.From US Pat. No. 4,171,473, there is also known a counting mechanism comprising three counting wheels arranged coaxially and in which each counting wheel meshes with a separate pinion, the pinions being arranged on the same axis with which they are integral in rotation. The differential movement of the counting wheels is obtained thanks to a different ratio between each pair of wheel and pinion. Each wheel has sliding zones and notches cooperating with rollers having the function of cutting levers. This device is complex and requires a pinion axis by counting mechanism, a pinion by counting wheel and a kinematic connection between each counting axis and the movement input axis. Furthermore, resetting to the start of counting is not easy, nor very fast because it is necessary, after having brought the door, roller shutter or the like in the desired stop position, to act axially on a thumb wheel to disengage the pinion axis from the input axis, then drive it manually in rotation until the counting wheels of the counting mechanism assume the position allowing all the rollers of the cutting mechanism to simultaneously penetrate into the notches of the counting wheels. If the counting wheels are in any position, the operation may take a long time.

L'invention a pour but de réaliser un dispositif d'arrêt automatique à deux points d'arrêt plus simple et moins encombrant que les dispositifs antérieurs.The object of the invention is to provide an automatic stop device with two stop points which is simpler and less bulky than the prior devices.

Le dispositif d'arrêt automatique selon l'invention est caractérisé en ce que les roues de comptage, les leviers de coupure et les leviers de mise à zéro propres à chacun des mécanismes de comptage sont pivotés dans un berceau commun articulé, par rapport à un bâti fixe portant le pignon d'entrée et les interrupteurs, autour d'un axe parallèle à l'axe des roues de comptage, de telle sorte que chacun des ces berceaux peut pivoter d'une première position, dans laquelle les roues de comptage sont en prise avec le pignon, vers une seconde position, dans laquelle les roues de comptage sont écartées dudit pignon, et en ce que le bâti fixe présente des parties profilées destinées à coopérer avec les leviers de coupure et les leviers de mise à zéro lors du déplacement des berceaux, de manière à assurer la mise à zéro des cames coeur et la fermeture de l'interrupteur correspondant lorsque les berceaux sont amenés dans leur seconde position, des ressorts étant prévus pour maintenir les roues de comptage engrenées, les doigts de coupure en appui sur les cames à encoche et les leviers de mise à zéro en appui sur les parties profilées correspondantes du bâti fixe.The automatic stop device according to the invention is characterized in that the counting wheels, the cut-off levers and the zeroing levers specific to each of the counting mechanisms are pivoted in a common articulated cradle, relative to a fixed frame carrying the input pinion and the switches, about an axis parallel to the axis of the counting wheels, so that each of these cradles can pivot from a first position, in which the counting wheels are in engagement with the pinion, towards a second position, in which the counting wheels are spaced from said pinion, and in that the fixed frame has profiled parts intended to cooperate with the cut-off levers and the zeroing levers during displacement of the cradles, so as to ensure the zero setting of the heart cams and the closing of the corresponding switch when the cradles are brought into their second position, springs being pr seen to keep the counting wheels meshed, the cutting fingers pressing on the notched cams and the zeroing levers pressing on the corresponding profiled parts of the fixed frame.

Chaque berceau, avec ses roues de comptage, son levier de coupure et son levier de mise à zéro, constitue une unité relativement simple et dont la précision est facile à assurer. Le mécanisme de transmission de la commande de débrayage et de mise à zéro de l'art antérieur est supprimé au profit de simples contours profilés du bâti jouant le rôle de cames fixes commandant le mouvement du levier de mise à zéro et du levier de coupure lors du pivotement du berceau.Each cradle, with its counting wheels, its cut-off lever and its zero-setting lever, constitutes a relatively simple unit whose precision is easy to ensure. The transmission mechanism of the disengaging and zeroing control of the prior art is eliminated in favor of simple profiled contours of the frame acting as fixed cams controlling the movement of the zeroing lever and the cut-off lever during pivoting of the cradle.

Les roues de comptage sont de préférence entraînées par un pignon d'entrée commun à deux dentures différentes. Dans chaque mécanisme de comptage certaines des roues sont en prise avec l'une des dentures et les autres avec l'autre denture.The counting wheels are preferably driven by a common input gear with two different teeth. In each counting mechanism, some of the wheels are engaged with one of the teeth and the others with the other teeth.

Selon une exécution préférée de l'invention, les ressorts sont réduits au nombre de deux pour l'ensemble du dispositif, l'un de ces ressorts reliant entre eux les leviers de coupure des deux mécanismes de comptage et assurant simultanément le maintien embrayé des roues de comptage, et l'autre ressort reliant entre eux les leviers de mise à zéro des deux mécanismes de comptage. Comparativement, un dispositif selon le brevet français 2 455 695 comporte trois ressorts par mécanisme de comptage, sans compter le ressort de maintien en position de l'élément de renvoi à engrènement intermittent.According to a preferred embodiment of the invention, the springs are reduced to two for the whole of the device, one of these springs connecting together the cut-off levers of the two counting mechanisms and simultaneously ensuring that the wheels are engaged. and the other spring connecting the zeroing levers of the two counting mechanisms to each other. In comparison, a device according to French patent 2 455 695 comprises three springs by counting mechanism, without counting the spring for holding in position the return element with intermittent meshing.

Les mécanismes de comptage pouvant être disposés de part et d'autre de l'axe d'entrée, de préférence symétriquement, l'encombrement axial d'un dispositif à deux points d'arrêt est le même que celui d'un dispositif à un seul point d'arrêt.The counting mechanisms can be arranged on either side of the input axis, preferably symmetrically, the axial size of a device with two breakpoints is the same as that of a single breakpoint device.

Le dessin annexé représente, à titre d'exemple, un mode d'exécution du dispositif selon l'invention.The accompanying drawing shows, by way of example, an embodiment of the device according to the invention.

La figure 2 est une vue en coupe selon II-II de la figure 1, la partie à gauche de l'axe de symétrie étant représentée sans le levier de mise à zéro, tandis que la partie à droite de l'axe est représentée sans le levier de coupure.Figure 2 is a sectional view along II-II of Figure 1, the part to the left of the axis of symmetry being shown without the zeroing lever, while the part to the right of the axis is shown without the cut-off lever.

La figure 3 est une vue analogue à celle de la figure 1 dans laquelle l'un des berceaux est représenté en position de débrayage et mise à zéro.Figure 3 is a view similar to that of Figure 1 in which one of the cradles is shown in the disengaged position and set to zero.

Le dispositif représenté comprend un bâti 1 dans lequel est pivoté un arbre 2 portant un long pignon présentant, sur sa longueur, deux dentures différentes 3 et 4. L'arbre 2 est destiné à être entraîné par le moteur d'entraînement de la porte, store, volet roulant ou analogue, plus précisément par la sortie du réducteur associé à ce moteur. Sur le bâti 1 sont en outre montés, symétriquement à l'axe 2, deux berceaux identiques 5 et 5' montés pivotant sur le bâti 1 autour d'un axe commun 6 situé dans le plan de symétrie et du dispositif et ils sont munis d'un bras 5a, respectivement 5'a, par lequel ils peuvent être basculés manuellement au moyen de poussoirs non représentés.The device shown comprises a frame 1 in which is pivoted a shaft 2 carrying a long pinion having, along its length, two different teeth 3 and 4. The shaft 2 is intended to be driven by the drive motor of the door, blind, roller shutter or the like, more specifically by the output of the reduction gear associated with this motor. On the frame 1 are also mounted, symmetrically to the axis 2, two identical cradles 5 and 5 'pivotally mounted on the frame 1 around a common axis 6 located in the plane of symmetry and of the device and they are provided with 'an arm 5a, respectively 5'a, by which they can be tilted manually by means of pushers not shown.

Dans le berceau 5 sont montées coaxialement quatre roues de comptage 7, 8, 9, 10 libres en rotation sur un axe commun. Les roues 7 et 8 présentent un nombre de dents différent et il en est de même des roues 9 et 10. Chacune des roues de comptage est flanquée d'un côté d'une came à encoche constituée d'une roue lisse coaxiale à la roue de comptage et dont la circonférence est interrompue par une encoche 19 (figure 1), et de l'autre côté d'une came coeur formant un bloc avec la roue de comptage. Les roues de comptage 7, 8, 9, 10 sont ainsi respectivement associées à une came à encoche 11, 12, 13, 14 et à une came coeur 15, 16, 17, 18.In the cradle 5 are coaxially mounted four counting wheels 7, 8, 9, 10 free to rotate on a common axis. The wheels 7 and 8 have a different number of teeth and the same is true of the wheels 9 and 10. Each of the counting wheels is flanked on one side by a notched cam consisting of a smooth wheel coaxial with the wheel counting and whose circumference is interrupted by a notch 19 (Figure 1), and on the other side of a heart cam forming a block with the counting wheel. The counting wheels 7, 8, 9, 10 are thus respectively associated with a notched cam 11, 12, 13, 14 and with a core cam 15, 16, 17, 18.

Dans le berceau 5 est en outre pivoté un levier de coupure 20 autour d'un axe 27 parallèle à l'axe 2. Ce levier de coupure 20 est muni de quatre doigts 21, 22, 23, 24 reliés rigidement au levier de coupure et coopérant respectivement avec les cames à encoche 11, 12, 13, 14. Le levier de coupure 20 est en outre muni à l'une de ses extrémités d'un bras coudé 25 relié rigidement au levier de coupure et destiné à actionner un premier interrupteur 26 fixé sur un prolongement du bâti 1.In the cradle 5 is further pivoted a cut-off lever 20 around an axis 27 parallel to the axis 2. This cut-off lever 20 is provided with four fingers 21, 22, 23, 24 rigidly connected to the cut-off lever and cooperating respectively with the notched cams 11, 12, 13, 14. The cut-off lever 20 is further provided at one of its ends with a bent arm 25 rigidly connected to the cut-off lever and intended to actuate a first switch 26 fixed on an extension of the frame 1.

Dans le berceau 5 est en outre pivoté, autour d'un axe 28 parallèle à l'axe 2, un levier de mise à zéro 29 muni de quatre bras constituant des marteaux destinés à actionner respectivement chacune des cames coeur 15 à 18. Sur la figure 2, le levier de mise à zéro et ses marteaux n'ont pas été représentés, de manière à voir clairement le levier de coupure. A la figure 1, seul l'un des marteaux 33 est visible.In the cradle 5 is further pivoted about an axis 28 parallel to the axis 2, a zeroing lever 29 provided with four arms constituting hammers intended to actuate each of the core cams 15 to 18 respectively. Figure 2, the zero lever and its hammers have not been shown, so as to clearly see the cut lever. In Figure 1, only one of the hammers 33 is visible.

Le second mécanisme de comptage monté dans le berceau 5' est réalisé de manière identique au premier mécanisme de comptage et comporte les mêmes éléments qui ont été désignés par les mêmes références que ceux du premier mécanisme de comptage accompagnées du signe ' de manière à éviter une répétition de la description. Le levier de mise à zéro 29' de ce second mécanisme de comptage est visible en plan dans la partie droite de la figure 2. On distingue les quatre marteaux de mise à zéro 30', 31', 32', 33'. Le levier de coupure 20' du second mécanisme n'a pas été représenté à la figure 2. On remarquera que la symétrie des deux mécanismes de comptage n'est totale, la position des cames à encoche et des cames coeur étant inversée par rapport à la position de ces éléments dans le premier mécanisme de comptage, les pièces constituées d'une roue de comptage, d'une came à encoche et d'une came coeur étant les mêmes pour les deux mécanismes de comptage. Les doigts de coupure et les marteaux de mise à zéro se trouvent en conséquence décalés relativement aux mêmes éléments du premier mécanisme de comptage.The second counting mechanism mounted in the cradle 5 'is produced in an identical manner to the first counting mechanism and comprises the same elements which have been designated by the same references as those of the first counting mechanism accompanied by the sign 'so as to avoid repetition of the description. The zeroing lever 29 ′ of this second counting mechanism is visible in plan on the right side of FIG. 2. There are the four zeroing hammers 30 ′, 31 ′, 32 ′, 33 ′. The cut-off lever 20 ′ of the second mechanism has not been shown in FIG. 2. It will be noted that the symmetry of the two counting mechanisms is not complete, the position of the notched cams and of the core cams being reversed with respect to the position of these elements in the first counting mechanism, the parts consisting of a counting wheel, a notched cam and a core cam being the same for the two counting mechanisms. The cutting fingers and the zeroing hammers are therefore offset relative to the same elements of the first counting mechanism.

Le bras coudé 25' du levier de coupure du second mécanisme de comptage coopère avec un second interrupteur 26' fixé comme l'interrupteur 26.The bent arm 25 'of the cut-off lever of the second counting mechanism cooperates with a second switch 26' fixed like the switch 26.

Les leviers de coupure 20 et 20' sont reliés entre eux par un premier ressort de traction 34 qui a simultanément pour effet de maintenir les doigts de coupure en appui sur les cames à encoche et de maintenir les roues de comptage des deux mécanismes en prise avec les dentures 3 et 4 du pignon d'entrée. Les leviers de mise à zéro 29 et 29' des deux mécanismes sont également reliés par un second ressort de traction 35 qui fournit la force nécessaire à l'actionnement des cames coeur.The cut-off levers 20 and 20 'are interconnected by a first tension spring 34 which simultaneously has the effect of keeping the cut-off fingers in contact with the notched cams and of keeping the counting wheels of the two mechanisms engaged with the teeth 3 and 4 of the input pinion. The zeroing levers 29 and 29 ′ of the two mechanisms are also connected by a second tension spring 35 which provides the force necessary for the actuation of the heart cams.

Le bâti 1 présente, de chaque côté, des parties profilées 36 et 37, respectivement 36' et 37' jouant le rôle de cames pour la commande du mouvement des leviers de mise à zéro 29 et 29' et des leviers de coupure 20 et 20'.The frame 1 has, on each side, profiled parts 36 and 37, respectively 36 'and 37' playing the role of cams for controlling the movement of the levers of zero setting 29 and 29 'and cut-off levers 20 and 20'.

Dans la partie gauche de la figure 1, on voit distinctement la forme de la partie profilée 36 en forme de saillie latérale présentant à son extrémité une rampe sur laquelle s'appuie un bec 38 constituant l'extrémité du levier de mise à zéro 29.In the left-hand part of FIG. 1, we can clearly see the shape of the profiled part 36 in the form of a lateral projection having at its end a ramp on which a spout 38 which constitutes the end of the zero-setting lever 29 rests.

Alors que les leviers de mise à zéro 29 et 29' sont en appui sur les parties profilées 36 et 36' lorsque les roues de comptage sont en prise avec le pignon d'entrée, les parties profilées 37 et 37' n'entrent en contact que momentanément avec les bras coudés 25 et 25' des leviers de coupure lors de la mise à zéro, comme ceci sera décrit plus loin en relation avec la figure 3.While the zeroing levers 29 and 29 'are supported on the profiled parts 36 and 36' when the counting wheels are engaged with the input pinion, the profiled parts 37 and 37 'do not come into contact that momentarily with the bent arms 25 and 25 ′ of the cut-off levers during zeroing, as will be described later in relation to FIG. 3.

Sur les figures 1 et 2, les doigts de coupure 21 à 24 sont représentés engagés dans les encoches des cames à encoche 11 à 14, ce qui signifie que le premier mécanisme de comptage est dans une position d'arrêt, le bras coudé 25 du levier de coupure agissant sur l'interrupteur 26 sous l'effet du ressort 34. Par contre, les doigts de coupure du second mécanisme de comptage ne sont pas engagés dans les encoches des cames à encoche 11' à 14'. Le second mécanisme est donc dans une position intermédiaire dans laquelle le bras coudé 25' est maitenu écarté de l'interrupteur 26'.In FIGS. 1 and 2, the cutting fingers 21 to 24 are shown engaged in the notches of the notched cams 11 to 14, which means that the first counting mechanism is in a stopped position, the bent arm 25 of the cut-off lever acting on the switch 26 under the effect of the spring 34. On the other hand, the cut-off fingers of the second counting mechanism are not engaged in the notches of the notched cams 11 'to 14'. The second mechanism is therefore in an intermediate position in which the bent arm 25 'is kept away from the switch 26'.

Le dispositif est utilisé avec un moteur à deux enroulements permettant d'assurer la rotation du moteur selon deux sens de rotation. L'interrupteur 26 est branché en série avec l'un des enroulements du moteur et un interrupteur de commande d'un premier sens de rotation, tandis que l'autre interrupteur 26' est branché en série avec le second enroulement du moteur et un interrupteur de commande du second sens de rotation.The device is used with a motor with two windings allowing the motor to rotate in two directions of rotation. Switch 26 is connected in series with one of the motor windings and a switch for controlling a first direction of rotation, while the other switch 26 'is connected in series with the second motor winding and a switch for controlling the second direction of rotation.

Une pression verticale sur le bras 5'a du berceau 5 a pour effet de faire basculer celui-ci autour de son axe 6 comme représenté à la figure 3. Les roues de comptage sont débrayées des dentures 3 et 4 du pignon d'entrée et, lors de ce basculement, le bec 38' du levier de mise à zéro 29' quitte la partie profilée 36' permettant au levier de mise à zéro 29' de pivoter en direction des cames coeur. Sous l'effet du ressort 35, les marteaux de mise à zéro 30' à 33' agissent sur chacune des cames coeur 15' à 18' et alignent les encoches des cames à encoche 11' à 14'. Le bras coudé 25' du levier de coupure vient buter contre la partie profilée 37' du bâti et il est écarté de l'interrupteur 26'. Lorsqu'on relâche ensuite la pression sur le bras d'actionnement 5'a du berceau 5', celui-ci revient dans sa position initiale, les leviers de mise à zéro et de coupure occupant alors la position représentée dans la partie gauche de la figure 1, c'est-à-dire doigts de coupure dans les encoches des cames à encoche et interrupteur 26 actionné par le bras coudé 25.A vertical pressure on the arm 5'a of the cradle 5 has the effect of tilting the latter around its axis 6 as shown in FIG. 3. The counting wheels are disengaged from the teeth 3 and 4 of the input pinion and , during this tilting, the spout 38 'of the zeroing lever 29' leaves the profiled part 36 'allowing the zeroing lever 29' to pivot in the direction of the heart cams. Under the effect of the spring 35, the zeroing hammers 30 'to 33' act on each of the heart cams 15 'to 18' and align the notches of the notched cams 11 'to 14'. The bent arm 25 ′ of the cutting lever abuts against the profiled part 37 ′ of the frame and it is moved away from the switch 26 ′. When the pressure is then released on the actuating arm 5'a of the cradle 5 ', the latter returns to its initial position, the zeroing and cut-off levers then occupying the position shown in the left-hand part of the FIG. 1, that is to say cutting fingers in the notches of the notched cams and switch 26 actuated by the bent arm 25.

Le réglage des points d'arrêt du dispositif s'effectue comme suit :The setting of the stopping points of the device is carried out as follows:

L'interrupteur de commande de sens 1 étant activé, c'est-à-dire fermé, le berceau 5 du premier mécanisme de comptage est amené dans sa position de débrayage et de mise à zéro correspondant à la position 5' représentée à la figure 3. Le premier enroulement du moteur est alimenté et l'organe contrôlé (porte, store ou volet roulant) est entraîné. Lorsque le premier point d'arrêt automatique souhaité est atteint, le berceau 5 est relâché et vient occuper la position représentée à la figure 1. L'interrupteur 26 est actionné et le moteur n'est plus alimenté.The direction control switch 1 being activated, that is to say closed, the cradle 5 of the first counting mechanism is brought into its declutching and zeroing position corresponding to the position 5 'shown in the figure 3. The first winding of the motor is supplied and the controlled component (door, blind or roller shutter) is driven. When the first desired automatic stop point is reached, the cradle 5 is released and comes to occupy the position shown in FIG. 1. The switch 26 is actuated and the motor is no longer supplied.

On procède de manière similaire pour régler le second point d'arrêt automatique en actionnant l'interrupteur de commande de sens 2 et en déplaçant le berceau 5' comme représenté à la figure 3. Dès que le second point d'arrêt souhaité est atteint, on relâche le berceau 5' dont les leviers viennent occuper la même position que celle du berceau 5 de la figure 1.We proceed in a similar way to set the second automatic stop point by actuating the direction control switch 2 and moving the cradle 5 'as shown in FIG. 3. As soon as the second desired stop point is reached, the cradle 5 ′ is released, the levers of which occupy the same position as that of the cradle 5 in FIG. 1.

Pendant le réglage du second point d'arrêt, les roues de comptage du premier mécanisme de comptage ont été entraînées en rotation et les encoches des roues à encoche ne coïncident plus. Les leviers du premier mécanisme occupent la position représentée à la figure 3.During the setting of the second stop point, the counting wheels of the first counting mechanism were rotated and the notches of the notched wheels no longer coincide. The levers of the first mechanism occupy the position shown in FIG. 3.

Le fonctionnement en période d'utilisation sera décrit à partir de la position représentée à la figure 1. Dans cette position, le dispositif réglé est dans sa première position d'arrêt. L'interrupteur 26 est ouvert et une action sur l'interrupteur de commande du premier sens reste sans effet. Une action sur l'interrupteur de commande de second sens de rotation a par contre pour effet d'alimenter le moteur et d'entraîner l'organe contrôlé jusqu'à ce que les encoches des roues à encoches du second mécanisme de comptage arrivent en alignement permettant au levier de coupure 20' de basculer et d'actionner l'interrupteur 26' entraînant l'arrêt du moteur dans sa seconde position d'arrêt.Operation during periods of use will be described from the position shown in FIG. 1. In this position, the adjusted device is in its first stop position. The switch 26 is open and an action on the first direction control switch has no effect. An action on the second direction of rotation control switch on the other hand has the effect of powering the motor and driving the controlled member until the notches of the notched wheels of the second counting mechanism arrive in alignment allowing the cut-off lever 20 'to switch and actuate the switch 26' causing the engine to stop in its second stop position.

Pendant ce temps, les roues de comptage du premier dispositif de comptage ont été entraînées et leurs encoches ne sont plus alignées, de telle sorte qu'au moins l'un des doigts de coupure est en appui sur la partie circulaire de la roue à encoche correspondante et que l'interrupteur correspondant n'est pas actionné, comme représenté à la figure 3.During this time, the counting wheels of the first counting device have been driven and their notches are no longer aligned, so that at least one of the cutting fingers is in contact with the circular part of the corresponding notched wheel and the corresponding switch is not actuated, as shown in FIG. 3.

Le dispositif décrit est bien entendu susceptible de variantes. En particulier, le nombre de roues de comptage de chaque mécanisme de comptage pourrait être différent de quatre, mais pratiquement il faut prévoir au minimum trois roues de comptage, par exemple deux roues engrenant avec la denture 3 et une roue engrenant avec la denture 4. Chaque mécanisme de comptage peut comprendre par exemple deux fois trois roues coopérant respectivement avec les dentures 3 et 4 ou trois roues engrenant avec l'une des dentures et deux roues avec l'autre denture du pignon d'entrée. Au lieu de deux ressorts commun aux deux mécanismes, il pourrait être prévu des ressorts propres à chaque mécanisme.The device described is of course subject to variations. In particular, the number of counting wheels for each counting mechanism could be different from four, but practically a minimum of three counting wheels must be provided, for example two wheels meshing with teeth 3 and one wheel meshing with teeth 4. Each counting mechanism can for example comprise two times three wheels cooperating respectively with the teeth 3 and 4 or three wheels meshing with one of the teeth and two wheels with the other teeth of the input pinion. Instead of two springs common to the two mechanisms, provision could be made for springs specific to each mechanism.

Le dispositif pourrait comporter deux pignons d'entrée parallèles, un pour chaque mécanisme de comptage.The device could include two parallel input gears, one for each counting mechanism.
