Abstract

Uses bistable mechanical actuator (11) comprising one piece movable cylinder (14) with both translation and rotation movement in fixed tube (13) to which it is linked , by interaction of guide finger (16), to ramp (15). The part (14) is pushed by spring (18) in direction of a switch and connected to manually activated traction part (17), which exerts force opposite to that of the spring. The actuator is brought to stable state either by the rotation of motor casing, or by the part . Controller for an electric motor driving a movable part, it includes a switch (12) controlling the motor supply and switch actuator reacting to retain the movable part to initiate opening of the switch and interrupt the supply. The actuator can occupy a first state in which the switch is closed and a second state in which the switch is open. A manual means (17) is used to put the actuator in its first state and is moved into its second state by retention of the movable part. The mechanical actuator is a bistable unit. The motor casing (3) is capable of turning through a limited angle around its axis, against the action of a spring (6,7), under the effect of a torque created by the movable part.

Description

La présente invention a pour objet un dispositif de commande d'un moteur électrique entraínant un mobile, par exemple un volet roulant ou une porte, comprenant un interrupteur contrôlant l'alimentation du moteur et des moyens d'actionnement de cet interrupteur réagissant à une retenue du mobile, en particulier par un obstacle, pour provoquer l'ouverture dudit interrupteur et couper l'alimentation du moteur, ces moyens d'actionnement comprenant un dispositif mécanique d'actionnement pouvant occuper un premier état dans lequel l'interrupteur est fermé et un second état dans lequel l'interrupteur est ouvert, et des moyens pour mettre le dispositif mécanique d'actionnement dans son premier état, le dispositif d'actionnement étant amené dans son second état par la retenue du mobile.The present invention relates to a device for control of an electric motor driving a mobile, for example a roller shutter or a door, comprising a switch controlling the power supply to the motor and means for actuating this switch reacting to restraint of the mobile, in particular by an obstacle, to cause the opening of said switch and cut off the power to the motor, these actuating means comprising a device actuation mechanics that can occupy a first state in which the switch is closed and a second state in which the switch is open, and means for putting the mechanical device in its first state, the device actuation being brought into its second state by the mobile restraint.

Un tel dispositif est connu de la demande de brevet DE 27 34 512. Dans ce dispositif, l'interrupteur commandant l'alimentation du moteur est ouvert au repos et sa fermeture est assurée par un mécanisme centrifuge entraíné par le moteur, le lancement du moteur étant assuré par un relais de démarrage à chute retardée commandé par un interrupteur manuel à poussoir. Les moyens de mise en marche du moteur et les moyens d'arrêt automatique en cas de surcouple sont ainsi associés, mais en plus de sa relative complexité, un tel dispositif nécessite un câblage particulier pour l'alimentation du relais de démarrage.Such a device is known from the DE patent application 27 34 512. In this device, the switch controlling the motor supply is open at rest and its closing is ensured by a centrifugal mechanism driven by the engine, the engine starting being ensured by a delayed fall start relay controlled by a manual push button switch. The means of starting the engine and the means automatic shutdown in the event of overtorque are thus associated, but in addition to its relative complexity, a such device requires special wiring for the starter relay supply.

Du brevet EP 0 703 344, on connaít par ailleurs un dispositif de commande d'un volet roulant motorisé opérant par la détection d'une soudaine augmentation du couple résistant exercée par le volet roulant sur le moteur. A cet effet, le bâti du moteur est monté rotativement et sa rotation est limitée par deux ressorts antagonistes déterminant le surcouple à atteindre dans chaque sens de rotation pour que la rotation du bâti actionne un interrupteur qui coupe l'alimentation du moteur. La retenue du mobile peut être provoquée soit par son arrivée en fin de course, soit par un obstacle. La mise en marche du moteur s'effectue, de manière conventionnelle, au moyen d'un commutateur.EP 0 703 344, we also know a motorized shutter control device operating by detecting a sudden increase in the resistant torque exerted by the roller shutter on the engine. For this purpose, the motor frame is mounted rotationally and its rotation is limited by two antagonistic springs determining the overtorque to reach in each direction of rotation so that the rotation of the frame actuates a switch which cuts motor power. Mobile restraint can be caused either by arriving at the end of the race, either by an obstacle. Starting the engine is carried out, in a conventional manner, by means of a switch.

La présente invention a également pour but d'associer les moyens d'arrêt automatique du moteur à la commande manuelle de la mise en marche du moteur, mais par des moyens mécaniques simples ne nécessitant pas de câblage auxiliaire et utilisant une commande manuelle mécanique, telle qu'une commande à tringle, à câble ou à cordon.The present invention also aims to associate the means of automatically stopping the engine when ordered starting the engine manually, but by simple mechanical means requiring no wiring auxiliary and using manual control mechanical, such as a rod, cable or cord.

Le dispositif de commande selon l'invention est caractérisé en ce que le dispositif mécanique d'actionnement est un dispositif bistable et en ce que les moyens pour mettre le dispositif d'actionnement dans son premier état sont exclusivement manuels.The control device according to the invention is characterized in that the mechanical device actuator is a bistable device and in that the means to put the actuating device in its first state are exclusively manual.

L'invention est applicable aussi bien à un moteur à un sens de rotation qu'à un moteur à deux sens de rotation. The invention is equally applicable to an engine with a direction of rotation than a two-way motor rotation.

Le dispositif ne nécessite pas d'autre câblage extérieur que celui nécessaire à l'alimentation du moteur. L'installation s'en trouve donc simplifiée.The device does not require any other wiring external than that necessary to supply the engine. Installation is therefore simplified.

Dans son exécution la plus simple, le dispositif d'actionnement est une came rotative actionnant un interrupteur monostable et présentant sur son pourtour une encoche dont la largeur angulaire correspondant à la rotation de la came nécessaire à l'actionnement de l'interrupteur et dans laquelle est engagé un doigt du carter du moteur pour son entraínement lorsque le carter du moteur est entraíné en rotation, contre l'action d'un ressort, par le couple résistant.In its simplest execution, the device actuator is a rotary cam actuating a monostable switch and presenting on its periphery a notch whose angular width corresponding to the rotation of the cam necessary for the actuation of the switch and in which a finger is engaged crankcase for its drive when the motor housing is rotated, against the action of a spring, by the resistant torque.

Selon un autre mode de réalisation, le dispositif mécanique bistable est constitué d'une pièce cylindrique mobile en translation et en rotation dans une pièce tubulaire cylindrique fixe à laquelle elle est liée par l'interaction d'au moins un ergot guidé par au moins une rampe, cette pièce mobile étant, d'une part, poussée par un ressort en direction de l'interrupteur et, d'autre part, reliée à un organe de traction actionnable manuellement, permettant d'exercer une traction opposée à la poussée du ressort, le dispositif étant amené dans son second état stable, soit par la rotation du carter du moteur contre l'action d'un ressort, cette rotation du carter étant provoquée par le couple résistant créé par la retenue dudit mobile, soit par une nouvelle traction sur l'organe de traction. According to another embodiment, the device mechanical bistable consists of one piece cylindrical mobile in translation and rotation in a fixed cylindrical tubular part to which it is linked by the interaction of at least one guided lug by at least one ramp, this moving part being, of a part, pushed by a spring towards the switch and, on the other hand, connected to a body of manually actuated traction for exercising traction opposite the spring thrust, the device being brought into its second stable state, either by the rotation of the motor housing against the action of a spring, this rotation of the casing being caused by the resistant torque created by the restraint said mobile, either by a new traction on the traction member.

Les figures 4a, 4b, 4c, 4d et 4e représentent cinq états successifs du dispositif bistable utilisés dans le mode d'exécution représenté à la figure 3.Figures 4a, 4b, 4c, 4d and 4e show five successive states of the bistable device used in the embodiment shown in Figure 3.

La figure 8 est une vue en coupe selon VIII-VIII de la figure 7. Figure 8 is a sectional view along VIII-VIII of the figure 7.

La figure 9 est une vue schématique partielle en coupe radiale d'un troisième mode d'exécution.Figure 9 is a partial schematic sectional view radial of a third embodiment.

La figure 10 est une coupe selon X-X de la figure 9.FIG. 10 is a section along X-X of FIG. 9.

A la figure 1, C désigne une commande manuelle, par exemple un cordon souple à tirer ou une tringle rigide à pousser/tirer, B un dispositif d'actionnement bistable, M un moteur dont le carter peut pivoter autour de l'axe du moteur contre l'action d'un ressort de retenue et D un détecteur de décalage angulaire entre le carter du moteur M et un point fixe. Le moteur M entraíne une charge L, par exemple un volet roulant. En supposant initialement que l'interrupteur d'alimentation du moteur est ouvert, c'est-à-dire que le dispositif d'actionnement B est dans un premier état stable P, une action de l'utilisateur sur la commande C a pour effet de faire basculer le dispositif bistable B de son état P dans son état P. Si, dans cet état, le détecteur de décalage angulaire D ne détecte pas de décalage angulaire, le moteur M est énergisé. Cette fonction peut s'écrire M = (P & S).In FIG. 1, C designates a manual control, by example a flexible cord to pull or a rigid rod push / pull, B an actuating device bistable, M a motor whose housing can pivot around the axis of the motor against the action of a spring and D an angular offset detector between the motor housing M and a fixed point. Engine M causes a load L, for example a roller shutter. Assuming initially that the switch motor supply is open, i.e. the actuator B is in a first state stable P, user action on command C has the effect of tilting the bistable device B from its P state to its P state. If, in this state, the angular offset detector D does not detect angular offset, the motor M is energized. This function can be written M = (P & S).

Lorsque le détecteur D détecte un décalage angulaire du carter du moteur, il émet un signal de stop S au dispositif bistable B qui bascule alors dans son état P. Le moteur M n'est plus alimenté.When detector D detects an angular offset of the crankcase, it sends a stop signal S to the bistable device B which then switches to its state P. Motor M is no longer powered.

Le moteur représenté à la figure 2 est un moteur classique monophasé à deux enroulements et condensateur de déphasage, dans lequel chacun des enroulements joue le rôle d'enroulement auxiliaire selon que la tension d'alimentation est appliquée entre P1 et N ou P2 et N.The motor shown in Figure 2 is a motor classic single phase with two windings and capacitor phase shift, in which each of the windings plays the role of auxiliary winding depending on whether the voltage power is applied between P1 and N or P2 and N.

Le premier mode d'exécution sera décrit en relation avec les figures 3 et 4a à 4eThe first mode of execution will be described in relation with figures 3 and 4a to 4e

A la figure 3 est représenté un support cylindrique 1 constituant un point fixe, par exemple l'un des supports du tube d'enroulement d'un volet roulant motorisé. Ce support cylindrique 1 présente deux rainures longitudinales diamétralement opposées 2. Coaxialement au support cylindrique 1 et dans le prolongement de celui-ci se trouve un manchon cylindrique 3 solidaire du carter du moteur (non représenté) pouvant constituer le prolongement de ce carter. L'autre extrémité du carter du moteur est soutenue de manière à pouvoir tourner librement autour de son axe. Le manchon 3 est prolongé par deux barres longitudinales 4 et 5 fixées rigidement au manchon 3 et s'étendant respectivement dans chacune des rainures 2 du cylindre fixe 1. Ces barres 4 et 5 sont maintenues angulairement au moyen d'une paire de ressorts en V 6 et 7 insérés entre chaque barre et les parois de la rainure 2 correspondante. Le carter du moteur est donc maintenu angulairement élastiquement en position. Les barres 4 et 5 sont en outre reliées par une traverse 8 dans le manchon 3. Cette traverse 8 porte, en sa partie médiane, une paire de cames 9 et 10 disposées symétriquement relativement à un plan passant par l'axe de pivotement du manchon 3. La came 9 est prévue pour coopérer avec un premier dispositif d'actionnement bistable 11 et la came 10 pour coopérer avec un second dispositif d'actionnement bistable non représenté, disposé, comme les cames 9 et 10 symétriquement relativement au même plan diamétral de symétrie. Le dispositif bistable 11 actionne un interrupteur 12 qui commande l'alimentation du moteur pour l'un des sens de rotation. L'autre dispositif bistable commande un second interrupteur identique à l'interrupteur 12 et monté, comme le dispositif bistable, symétriquement relativement au même plan de symétrie.In Figure 3 is shown a cylindrical support 1 constituting a fixed point, for example one of the roller shutter tube supports motorized. This cylindrical support 1 has two diametrically opposite longitudinal grooves 2. Coaxial with cylindrical support 1 and in the extension of it is a sleeve cylindrical 3 secured to the motor housing (not represented) which may constitute an extension of this casing. The other end of the motor housing is supported so that it can rotate freely around of its axis. Sleeve 3 is extended by two bars longitudinal 4 and 5 rigidly fixed to the sleeve 3 and extending respectively in each of the grooves 2 of the fixed cylinder 1. These bars 4 and 5 are maintained angularly by means of a pair of V-shaped springs 6 and 7 inserted between each bar and the walls of the corresponding groove 2. The motor housing is therefore angularly elastically held in position. The bars 4 and 5 are further connected by a cross member 8 in the sleeve 3. This cross member 8 carries, in its part middle, a pair of cams 9 and 10 arranged symmetrically relative to a plane passing through the axis sleeve 3 pivoting point. The cam 9 is provided for cooperate with a first actuation device bistable 11 and cam 10 to cooperate with a second bistable actuator not shown, arranged like cams 9 and 10 symmetrically relatively to the same diametrical plane of symmetry. The bistable device 11 actuates a switch 12 which controls the motor supply for one of the directions of rotation. The other bistable device controls a second switch identical to switch 12 and mounted, like the bistable device, symmetrically relatively to the same plane of symmetry.

Le dispositif bistable 11 est constitué d'une pièce cylindrique tubulaire fixe 13 et d'une pièce cylindrique 14 mobile en rotation et en translation dans la pièce 13. La paroi de la pièce fixe 13 est découpée par une rainure 15 formant un circuit de rampes et de pièges pour un doigt radial 16 fixé sur la pièce mobile 14 traversant la rainure 15 avec un faible jeu et s'étendant radialement en dehors de la pièce 13 de manière à pouvoir être entraínée par la came 9, en ce qui concerne le bistable 11. La pièce mobile 14 est reliée à l'extrémité d'une tringle ou câble 17 de manière à ne pas être gênée dans sa rotation. La pièce mobile 14 est en outre soumise à l'action d'un ressort 18 travaillant en compression et tendant à pousser la pièce 14 en direction de l'interrupteur 12.The bistable device 11 consists of a part fixed tubular cylindrical 13 and one piece cylindrical 14 movable in rotation and in translation in room 13. The wall of the fixed room 13 is cut by a groove 15 forming a circuit ramps and traps for a radial finger 16 fixed on the moving part 14 crossing the groove 15 with a slight clearance and extending radially outside the part 13 so that it can be driven by the cam 9, in as regards the bistable 11. The movable part 14 is connected to the end of a rod or cable 17 of so as not to be hampered in its rotation. The room mobile 14 is further subjected to the action of a spring 18 working in compression and tending to push the part 14 in the direction of switch 12.

Le fonctionnement de ce mode d'exécution sera décrit en relation aux figures 4a à 4eThe operation of this embodiment will be described in relation to figures 4a to 4e

Dans la position représentée à la figure 4a, le doigt 16 de la pièce mobile 14 du bistable est maintenu par le ressort 18 dans l'extrémité gauche du circuit 15 proche de l'interrupteur 12. La pièce 14 est en appui contre le poussoir de l'interrupteur 12 et son contact 12a est ouvert : le moteur n'est pas alimenté. Si l'utilisateur exerce une traction sur la tringle 17 dans le sens de la flèche F1, la pièce 14 est tirée en arrière. Lors de ce mouvement, son doigt 16 glisse le long de la rampe 15a en entraínant la pièce 14, comme indiqué par la flèche F2. Le doigt 16 vient finalement buter contre la butée 15b.In the position shown in Figure 4a, the finger 16 of the movable part 14 of the bistable is held by the spring 18 in the left end of the circuit 15 close to the switch 12. The part 14 is in support against the switch 12 switch and its contact 12a is open: the motor is not supplied. Yes the user exerts traction on the rod 17 in the direction of arrow F1, the part 14 is pulled in back. During this movement, his finger 16 slides the along the ramp 15a by driving the part 14, as indicated by arrow F2. Finger 16 finally comes abut against the stop 15b.

Lorsque la traction sur la tringle 17 est relâchée, le doigt 16 vient s'engager dans le piège 15c du circuit 15, comme représenté à la figure 4b. Le dispositif bistable se trouve alors dans son second état stable. La pièce 14 est écartée de l'interrupteur 12, son contact est fermé et le moteur est alimenté.When the pull on the rod 17 is released, the finger 16 engages in circuit trap 15c 15, as shown in Figure 4b. The device bistable is then in its second stable state. The part 14 is moved away from the switch 12, its contact is closed and the motor is supplied.

Si le carter du moteur est alors entraíné en rotation par la retenue du mobile entraíné par le moteur, par exemple par l'arrivée en butée contre le caisson de l'extrémité d'un volet roulant lors de son enroulement, le manchon 3 pivote contre l'action de l'un des ressorts 6 ou 7, par exemple le ressort 7, et la came 9 vient entraíner le doigt 16 qui s'échappe de son piège 15c pour revenir à sa première position stable le long de la rainure 15, comme indiqué par la flèche F3, figure 4c, sous la poussée du ressort 18. L'interrupteur 12 est alors actionné, son contact 12a s'ouvre et l'alimentation du moteur est interrompue.If the motor housing is then rotated by retaining the mobile driven by the engine, by example by the arrival in abutment against the box of the end of a roller shutter when it is rolled up, the sleeve 3 pivots against the action of one of the springs 6 or 7, for example spring 7, and cam 9 comes to train finger 16 which escapes from its trap 15c to return to its first stable position along groove 15, as indicated by arrow F3, FIG. 4c, under the thrust of the spring 18. Switch 12 is then actuated, its contact 12a opens and the motor supply is interrupted.

L'arrêt peut être également commandé manuellement par une traction sur la tringle 17. Le dispositif bistable 11 opère dans ce cas comme représenté aux figures 4d et 4e. Lors de la traction sur 17, le doigt 16 vient buter contre la rampe 15d qui l'écarte du piège 15c. Une fois relâché, le doigt 16 se déplace axialement le long de 15e, la rampe 15f et le ramène dans la position représentée à la figure 4a.The stop can also be controlled manually by a pull on the rod 17. The bistable device 11 operates in this case as shown in FIGS. 4d and 4th. When pulling on 17, finger 16 abuts against the ramp 15d which separates it from the trap 15c. Once released, finger 16 moves axially along 15th, ramp 15f and bring it back to the position shown in Figure 4a.

Si les deux dispositifs d'actionnement bistables équipant le dispositif de commande sont indépendants, rien n'empêche l'utilisateur d'actionner simultanément ces deux dispositifs bistables, c'est-à-dire de donner deux ordres contradictoires. Ceci peut être évité mécaniquement ou électriquement.If the two bistable actuators equipping the control device are independent, nothing prevents the user from operating simultaneously these two bistable devices, that is to say to give two contradictory orders. This can be avoided mechanically or electrically.

La figure 5 illustre une solution mécanique. Les pièces mobiles 14 et 14' des deux dispositifs bistables présentent une gorge annulaire 19, respectivement 19'. Entre les deux pièces mobiles 14 et 14' est monté un tiroir 20 pouvant coulisser transversalement entre les deux dispositifs bistables et s'engager alternativement dans les gorges 19 et 19'. La longueur de ce chariot 20 est telle qu'il est toujours engagé dans l'une des gorges 19 ou 19'. Dans la position représentée à la figure 5, le chariot 20 est engagé par l'une de ses extrémités dans la gorge 19 de la pièce mobile 14, tandis que son autre extrémité est en butée contre la surface cylindrique de la pièce mobile 14'. La pièce 14 est ainsi verrouillée, de sorte qu'une traction sur sa tringle 17 est sans effet. Par contre, dès que la pièce 14' arrive en butée contre l'interrupteur 12', la pièce 14 est libérée. Figure 5 illustrates a mechanical solution. Rooms mobile 14 and 14 'of the two bistable devices have an annular groove 19, respectively 19 '. Between the two moving parts 14 and 14 'is mounted a drawer 20 which can slide transversely between the two bistable devices and engage alternately in the gorges 19 and 19 '. The length of this cart 20 is such that he is still engaged in one of 19 or 19 'gorges. In the position shown in Figure 5, the carriage 20 is engaged by one of its ends in the groove 19 of the moving part 14, while its other end is in abutment against the cylindrical surface of the moving part 14 '. Exhibit 14 is thus locked, so that a pull on its rod 17 has no effect. However, as soon as the room 14 'comes up against the switch 12', the part 14 is released.

Une solution électrique est représentée à la figure 6. L'un des interrupteurs, par exemple l'interrupteur 12, est équipé d'un contact inverseur permettant de relier la borne a, soit à la borne b, soit à la borne c, cette borne c étant reliée à l'interrupteur 12' de telle sorte que la fermeture de l'interrupteur 12' n'est efficace que si l'interrupteur 12 est actionné et inversement, l'actionnement de l'interrupteur 12 ayant pour effet d'amener le contact 12b dans la position représentée et son relâchement ayant pour effet de le faire revenir sur la borne b. An electrical solution is shown in FIG. 6. One of the switches, for example the switch 12, is equipped with a change-over contact making it possible to connect terminal a, either to terminal b , or to terminal c , this terminal c being connected to the switch 12 'so that the closing of the switch 12' is effective only if the switch 12 is actuated and vice versa, the actuation of the switch 12 having the effect of bring the contact 12b into the position shown and its release having the effect of causing it to return to the terminal b.

Le deuxième mode sera maintenant décrit en relation avec les figures 7 et 8.The second mode will now be described in relation with Figures 7 and 8.

Ces figures représentent l'une des extrémités d'une installation de volet roulant montée dans une embrasure. On retrouve le carter 3 du moteur tubulaire logé à l'intérieur d'un tube d'enroulement 21 partiellement représenté entraíné par le moteur. L'extrémité représentée du carter 3 est munie d'un flasque 22 par lequel il est monté dans un bâti rectangulaire 23 muni d'une découpe principale circulaire 24. Le flasque 22 est muni d'une couronne 25 engagée dans la découpe circulaire 24 dans laquelle elle peut tourner librement. Dans son point le plus bas, la couronne 25 est munie d'un premier doigt 26 dirigé vers le centre de la couronne et d'un second doigt radial 27 dirigé vers l'extérieur, dans une découpe rectangulaire 28 du bâti 23 dans laquelle sont logés deux ressorts antagonistes 29 et 29' travaillant en compression et s'appuyant sur chacun des côtés du doigt 27. Au centre de la couronne 25 est monté, fixe, un interrupteur 30 muni d'une bascule bistable 31, c'est-à-dire un interrupteur à borne centrale et deux contacts pour établir une liaison électrique entre la borne centrale et alternativement l'un ou l'autre des contacts, c'est-à-dire soit entre N et M1 ou N et M2(figure 2) pour faire tourner le moteur dans un sens ou dans l'autre. La partie visible de la bascule 31 présente un profil en V obtu. L'interrupteur 30 est porté par un support 32 fixé au bâti 23. Coaxialement à l'axe X du moteur et du tube d'enroulement est montée une came 33 présentant, dans sa partie inférieure, une encoche 34 s'étendant sur un angle bien déterminé, et une partie saillante 35 en forme de dièdre d'angle égal à l'angle du profil en V de la bascule 31 de l'interrupteur et engagée dans ce profil. Le doigt 26 est engagé dans l'encoche 34. L'espace entre chacune des extrémités de l'encoche 34 et le doigt 26 est égal au déplacement angulaire de la came 33 nécessaire à l'actionnement de la bascule 31, c'est-à-dire à la fermeture de l'interrupteur 30 dans une position ou dans l'autre. La came 33 peut être entraínée manuellement en rotation par un axe 36. Afin de ne pas risquer d'endommager l'interrupteur 30, la liaison entre l'axe 36 et la came 33 est une liaison élastique ou à friction.These figures represent one of the ends of a rolling shutter installation mounted in a embrasure. We find the casing 3 of the tubular motor housed inside a winding tube 21 partially shown driven by the engine. The illustrated end of the casing 3 is provided with a flange 22 by which it is mounted in a frame rectangular 23 with a main cutout circular 24. The flange 22 is provided with a crown 25 engaged in the circular cutout 24 in which it can rotate freely. In its most point bottom, the crown 25 is provided with a first finger 26 directed to the center of the crown and a second radial finger 27 directed outwards, in a rectangular cutout 28 of the frame 23 in which are housed two opposing springs 29 and 29 'working in compression and supported on each side of the finger 27. In the center of the crown 25 is mounted, fixed, a switch 30 provided with a bistable rocker 31, i.e. a central terminal switch and two contacts to establish an electrical connection between the central terminal and alternatively one or the other of contacts, i.e. either between N and M1 or N and M2 (figure 2) to turn the motor in one direction or in the other. The visible part of the scale 31 has an obtuse V-profile. Switch 30 is carried by a support 32 fixed to the frame 23. Coaxially with the X axis of the motor and the winding tube is mounted a cam 33 having, in its lower part, a notch 34 extending over a well-defined angle, and a projecting part 35 in the form of a dihedral of equal angle at the angle of the V-profile of the rocker 31 of the switch and engaged in this profile. Finger 26 is engaged in notch 34. The space between each of the ends of the notch 34 and the finger 26 is equal the angular displacement of the cam 33 necessary for the actuation of the flip-flop 31, that is to say at the closing of the switch 30 in a position or in the other. Cam 33 can be driven manually in rotation by an axis 36. In order not to risk of damaging the switch 30, the connection between the axis 36 and the cam 33 is an elastic connection or friction.

Le dispositif est représenté au repos, moteur arrêté. Pour mettre en marche le moteur, l'utilisateur tourne l'axe 36 dans un sens ou dans l'autre, selon le sens de rotation du moteur désiré. La rotation de la came 33 a pour effet, d'une part, de fermer l'interrupteur par le dièdre 35 et, d'autre part, d'amener l'un des côtés de l'encoche 34 contre le doigt 26. Supposons, par exemple, que la came 30 a été entraínée dans le sens des aiguilles d'une montre. C'est donc l'extrémité droite de l'encoche 34, figure 7, qui vient en contact avec le doigt 26. Lorsqu'un couple résistant parvient à faire tourner le carter 3 dans le sens contraire des aiguilles d'une montre, en comprimant le ressort 29', le doigt 26 entraíne la came 33 en rotation dans le même sens, ce qui a pour effet de ramener le dièdre 35 dans la position représentée, c'est-à-dire de ramener la bascule 31 de l'interrupteur dans la position représentée. L'alimentation du moteur est coupée. Après disparition du surcouple résistant, le ressort 29' ramène le carter 3 dans la position représentée.The device is shown at rest, engine stopped. To start the engine, the user turns axis 36 in one direction or the other, depending on the direction of rotation of the desired motor. The rotation of the cam 33 a on the one hand, to close the switch by the dihedral 35 and, on the other hand, to bring one of the sides of the notch 34 against the finger 26. Suppose, by example, that the cam 30 has been driven in the direction clockwise. So this is the end right of the notch 34, figure 7, which comes into contact with finger 26. When a resistant couple manages to rotate the housing 3 anticlockwise clockwise, compressing the spring 29 ', the finger 26 drives the cam 33 in rotation in the same direction, which has the effect of bringing the dihedral 35 in the position shown, that is to say to bring flip-flop 31 of the switch in the position represented. The motor supply is cut off. After disappearance of the resistant overtorque, the spring 29 ' returns the casing 3 to the position shown.

Dans cette exécution, le dispositif bistable est donc constitué par l'interrupteur lui-même.In this embodiment, the bistable device is therefore constituted by the switch itself.

Le troisième mode d'exécution représenté aux figures 9 et 10 est en fait une variante d'exécution du deuxième mode d'exécution dont elle reprend la plupart des éléments, en particulier les éléments non représentés. A la figure 9, on reconnaít la couronne 25 du flasque du carter 3 avec ses doigts radiaux 26 et 27. La came rotative 33' diffère de la came 33 en ce qu'elle présente une partie centrale saillante 37 engagée entre deux interrupteurs monostables 38 et 38' dont le contact est ouvert au repos, contrairement aux interrupteurs 12 et 12' du premier mode d'exécution. La partie saillante 37 de la came présente une forme telle qu'au repos, les interrupteurs 38 et 38' ne sont pas actionnés, alors qu'un entraínement en rotation de la came 33' par l'axe 36 actionne l'un ou l'autre des interrupteurs par la partie 37. On voit donc que la partie 37 peut prendre diverses formes et qu'elle pourrait aussi être divisée en deux parties, par exemple deux plots. Par ailleurs, le contour extérieur de la came 33', comme celui de la came 33, peut être quelconque, à l'exception de l'encoche 34.The third embodiment shown in Figures 9 and 10 is actually a variant of the second mode of execution from which it incorporates most of the elements, in particular elements not shown. In Figure 9, we recognize the crown 25 of the flange of the casing 3 with its radial fingers 26 and 27. The cam rotary 33 'differs from cam 33 in that it has a projecting central part 37 engaged between two monostable switches 38 and 38 'including the contact is open at rest, unlike switches 12 and 12 'of the first embodiment. The projection 37 of the cam has such a shape that at rest, the switches 38 and 38 'are not actuated, while a rotational drive of the cam 33 'by axis 36 activates one or other of the switches through part 37. So we see that the part 37 can take various forms and it could also be divided into two parts, by example two studs. In addition, the outer contour of cam 33 ', like that of cam 33, can be any, with the exception of notch 34.

Le fonctionnement de ce troisième mode d'exécution est le même que celui du deuxième mode d'exécution à la seule différence que la bistabilité est assurée ici par la came 33'. En position actionnée de l'un des interrupteurs, la stabilité de la came est assurée par le frottement du poussoir de l'interrupteur sur la came. Cette stabilité pourrait être augmentée en formant une légère dépression dans la partie 37. La stabilité dans la position neutre pourrait être assurée par frottement ou par un moyen auxiliaire tel qu'une bille montée élastiquement. Au moyen d'une telle bille, il serait possible d'assurer la stabilité de la came 33' dans ses trois positions. De tels moyens pourraient être également prévus sur un bouton d'entraínement de l'axe 36.The operation of this third embodiment is the same as that of the second embodiment at the only difference that bistability is ensured here by the cam 33 '. In the actuated position of one of the switches, the stability of the cam is ensured by the friction of the switch pusher on the cam. This stability could be increased by forming a slight depression in part 37. The stability in the neutral position could be ensured by friction or by an auxiliary means such as resiliently mounted ball. By means of such a ball, it would be possible to ensure the stability of the cam 33 'in its three positions. Such means could also be provided on a training button axis 36.
