Abstract

A locking mechanism includes a locking section (7) that can be rotated about an axis parallel to a main axis. The locking section can be made to pivot by a hand lever (2) in a temporary manner whenever an angular divergence between the hand lever and a transmission shaft exceeds a specified threshold. An independent claim is also included for an electrical switch.

Description

appareil électrique interrupteur, tel que par exemple un disjoncteur. L'invention a également pour objet un appareil électrique interrupteur intégrant un tel dispositif d'actionnement. Le dispositif d'actionnement est par exemple déporté par rapport à l'appareil électrique interrupteur.electrical apparatus switch, such as for example a circuit breaker. The invention also relates to an electrical switch device incorporating such an actuating device. The actuating device is for example offset relative to the electrical switch device.

Pour des raisons de sécurité, le verrouillage de la manette d'un dispositif d'actionnement pour appareil électrique interrupteur ne doit être possible que lorsque la manette se trouve dans la position "Arrêt". Pour cela, il est connu de doter le dispositif d'actionnement d'un dispositif de verrouillage de la manette lorsque celle-ci est dans sa position "Arrêt". Afin de maintenir la manette en position verrouillée, des cadenas sont accrochés à travers une ou plusieurs ouvertures formées sur la manette. Le brevet US 6,423,912 décrit notamment un tel dispositif de verrouillage.For safety reasons, it is only possible to lock the handle of a switchgear actuator when the handle is in the "Off" position. For this, it is known to provide the actuating device with a locking device of the handle when it is in its "off" position. In order to keep the handle in the locked position, padlocks are hooked through one or more openings formed on the handle. The patent US 6,423,912 describes in particular such a locking device.

Cependant, lorsque les contacts de l'appareil électrique interrupteur sont soudés entre eux suite par exemple à un court circuit, le verrouillage de la rotation de la manette en position "Arrêt" doit être rendu impossible étant donné qu'un opérateur pourrait croire que les contacts sont ouverts alors que ceux-ci sont en réalité fermés car soudés.However, when the contacts of the electrical switch device are welded together following for example a short circuit, locking the rotation of the handle in the "off" position must be made impossible since an operator might believe that the contacts are open while these are actually closed because welded.

Les brevets US 6,797,903 et US 5,222,382 (ou le correspondant EP 0 450 699 ) présentent des solutions permettant d'empêcher une telle situation. Dans ces brevets, la rotation de la manette vers sa position "Arrêt" alors que les contacts sont soudés entre eux, provoque la rotation d'un élément venant obturer le passage par lequel doit passer un organe de verrouillage. Même si l'opérateur force sur la manette pour la ramener en position "Arrêt", le verrouillage demeure impossible.Licences US 6,797,903 and US 5,222,382 (or the correspondent EP 0 450 699 ) present solutions to prevent such a situation. In these patents, the rotation of the handle to its "stop" position while the contacts are welded together, causes the rotation of an element from closing the passage through which must pass a locking member. Even if the operator forces the joystick back to the "Off" position, locking is still impossible.

Cependant, en forçant sur la manette pour tenter de la ramener dans sa position arrêt alors que les contacts sont soudés entre eux, l'opérateur peut endommager la manette et l'appareil électrique interrupteur. En outre, si en forçant sur la manette, l'opérateur parvient à décoller les contacts, il risque la création d'arcs électriques ce qui peut s'avérer dangereux.However, by forcing on the joystick to try to bring it back to its off position while the contacts are welded together, the operator can damage the controller and the electrical switch device. In addition, if by forcing on the controller, the operator manages to take off the contacts, it risks the creation of arcs which can be dangerous.

Le document EP 0 472 477 décrit un dispositif pour bloquer une poignée de disjoncteur lorsque les contacts sont soudés. Lors de la soudure des contacts, après passage d'un point mort par action manuelle, la poignée vient s'immobiliser et se bloquer dans une position intermédiaire stable, située entre la position d'ouverture et la position de fermeture. Dans cette position intermédiaire, une pièce déformable se déforme sous l'action de la poignée de sorte à venir en butée contre une butée fixe du dispositif.The document EP 0 472 477 discloses a device for locking a circuit breaker handle when the contacts are soldered. When soldering the contacts, after passing a neutral position by manual action, the handle comes to rest and lock in a stable intermediate position, located between the open position and the closed position. In this intermediate position, a deformable part deforms under the action of the handle so as to abut against a fixed stop of the device.

Dans un tel dispositif, la pièce déformable est particulièrement sollicitée et elle exerce la double fonction de détection du couple lorsqu'un opérateur tente de ramener la poignée vers la position ouverte alors que les contacts sont soudés et de limitation du couple en bloquant la rotation de la poignée contre la butée fixe lorsque les contacts sont soudés. La pièce doit ainsi présenter à la fois une certaine souplesse et une certaine rigidité pour exercer les deux fonctions. En outre, lors d'une soudure des contacts, en position intermédiaire de la poignée, la pièce déformable est sollicitée de manière permanente ce qui peut causer, si la pièce est usée, un retour de la poignée en position d'ouverture alors que les contacts sont soudés.In such a device, the deformable part is particularly stressed and it has the dual function of detecting the torque when an operator tries to return the handle to the open position while the contacts are welded and torque limiting by blocking the rotation of the handle against the fixed stop when the contacts are welded. The piece must thus have both flexibility and rigidity to perform both functions. In addition, during a welding of the contacts, in the intermediate position of the handle, the deformable part is permanently biased which may cause, if the part is worn, a return of the handle in the open position while the contacts are soldered.

Le but de l'invention est donc de proposer un dispositif d'actionnement fiable qui évite l'endommagement de la manette et de l'appareil électrique lorsqu'un opérateur tente de ramener la manette vers la position "Arrêt" alors que les contacts sont soudés entre eux et qui évite la naissance d'arc électrique si l'opérateur parvenait à décoller les contacts en tournant la manette vers sa position "Arrêt".The object of the invention is therefore to provide a reliable actuating device that avoids damage to the controller and the electrical device when an operator tries to return the handle to the "Stop" position while the contacts are welded between them and which avoids the birth of electric arc if the operator managed to take off the contacts by turning the handle to its "Stop" position.

Ce but est atteint par un dispositif d'actionnement pour un appareil électrique interrupteur comprenant :

  • un corps sur lequel est montée une manette rotative autour d'un axe principal, coopérant avec un axe de transmission apte à commander l'ouverture ou la fermeture de contacts électriques de l'appareil électrique interrupteur,
  • des moyens de liaison élastiques entre la manette et l'axe de transmission,
  • des moyens de blocage en rotation de la manette par rapport au corps, mis en oeuvre lorsqu'un écart angulaire entre la manette et l'axe de transmission dépasse un seuil déterminé, ledit dispositif étant caractérisé en ce que
  • les moyens de blocage comportent un organe de blocage rotatif autour d'un axe parallèle à l'axe principal, et en ce que
  • l'organe de blocage est sollicité en pivotement par la manette, de manière temporaire, à chaque fois que l'écart angulaire entre la manette et l'axe de transmission dépasse le seuil déterminé.
This object is achieved by an actuating device for a switch electrical apparatus comprising:
  • a body on which is mounted a rotary handle about a main axis, cooperating with a transmission axis adapted to control the opening or closing of electrical contacts of the electrical switch device,
  • elastic connection means between the handle and the transmission axis,
  • locking means in rotation of the lever relative to the body, implemented when an angular gap between the handle and the axis of transmission exceeds a determined threshold, said device being characterized in that
  • the locking means comprise a rotational locking member about an axis parallel to the main axis, and in that
  • the locking member is pivotally urged by the handle, temporarily, whenever the angular distance between the handle and the transmission axis exceeds the determined threshold.

Par rapport à l'enseignement du document US 5,222,382 cité ci-dessus, le blocage en rotation de la manette dans le dispositif de l'invention est donc réalisé par rapport au corps du dispositif. En outre, par rapport au dispositif décrit dans le document EP 0 472 477 , les fonctions de détection et de limitation du couple sont réalisées par deux moyens différents ce qui permet de fiabiliser le fonctionnement du dispositif au cours du temps. De plus, dans l'invention, l'organe de blocage n'est sollicité que temporairement, et ne bloque la manette qu'à chaque tentative de retour de la manette en position arrêt alors que les contacts sont soudés. La manette ne marque aucune position intermédiaire dans laquelle l'organe de blocage est sollicité de manière permanente.In relation to the teaching of the document US 5,222,382 cited above, the locking in rotation of the handle in the device of the invention is made with respect to the body of the device. In addition, compared to the device described in the document EP 0 472 477 the detection and limitation of the torque functions are performed by two different means which makes reliable operation of the device over time. In addition, in the invention, the locking member is solicited only temporarily, and only blocks the handle when each attempt to return the handle in the off position while the contacts are welded. The lever does not mark any intermediate position in which the locking member is permanently biased.

Selon une particularité, l'organe de blocage est solidaire en rotation de l'axe de transmission.According to one feature, the locking member is integral in rotation with the transmission axis.

Selon une autre particularité, l'organe de blocage est mobile entre une position de repos dans laquelle il est solidaire en rotation de la manette et une position de travail dans laquelle, pivoté par la manette lorsque l'écart angulaire entre la manette et l'axe de transmission dépasse le seuil déterminé, il s'appuie contre le corps du dispositif et bloque la rotation de la manette.According to another feature, the locking member is movable between a rest position in which it is rotatably connected to the handle and a working position in which, pivoted by the handle when the angular gap between the handle and the transmission axis exceeds the determined threshold, it rests against the body of the device and blocks the rotation of the joystick.

Selon une autre particularité, l'organe de blocage comporte au moins une came contre laquelle s'appuie une partie de la manette pour être entraîné en pivotement.According to another feature, the locking member comprises at least one cam against which a portion of the lever rests to be pivotally driven.

Selon une autre particularité, l'organe de blocage peut comporter deux cames formées symétriquement par rapport à un plan passant par son axe et l'axe principal. La partie de la manette en suivant l'une des cames entraîne l'organe de blocage en pivotement dans un sens ou dans l'autre. L'organe de blocage, en pivotant, s'appuie donc contre le corps du dispositif et bloque alors la rotation de la manette. Avec deux cames symétriques, un organe de blocage de cette configuration permet de bloquer la manette dans un sens de rotation ou dans l'autre.According to another feature, the locking member may comprise two cams formed symmetrically with respect to a plane passing through its axis and the main axis. The portion of the handle following one of the cams causes the locking member pivoting in one direction or the other. The locking member, pivoting, therefore leans against the body of the device and then blocks the rotation of the joystick. With two symmetrical cams, a locking member of this configuration makes it possible to lock the lever in one direction of rotation or the other.

Selon l'invention, le pivotement de l'organe de blocage est réalisé dans le sens opposé à celui de rotation de la manette.According to the invention, the pivoting of the locking member is in the opposite direction to that of rotation of the handle.

Selon l'invention, l'organe de blocage comporte des dents aptes à coopérer avec des dents correspondantes formées sur le corps.According to the invention, the locking member comprises teeth capable of cooperating with corresponding teeth formed on the body.

Selon une particularité, l'organe de blocage est sollicité de sa position de travail vers sa position de repos par un ressort de rappel. L'organe de blocage peut également être ramené vers sa position de repos naturellement en suivant la came en sens inverse.According to one feature, the locking member is biased from its working position to its rest position by a return spring. The locking member can also be returned to its rest position naturally by following the cam in the opposite direction.

Selon l'invention, les moyens de liaison élastiques sont par exemple constitués d'une lame ressort. L'utilisation d'autres moyens de liaison peut être envisagée. La lame ressort a par exemple une forme trapézoïdale afin de mieux répartir les efforts s'exerçant entre la manette et l'axe de transmission.According to the invention, the elastic connection means consist for example of a spring blade. The use of other connecting means can be envisaged. The spring blade has for example a trapezoidal shape to better distribute the forces exerted between the handle and the transmission axis.

Le dispositif d'actionnement décrit ci-dessus est parfaitement adapté pour la commande d'un appareil électrique interrupteur et peut être monté sur une armoire dans laquelle est placé l'appareil électrique interrupteur. Dans ce cas, l'axe de transmission est solidaire d'un organe mobile rotatif de l'appareil électrique interrupteur.The actuating device described above is perfectly suitable for controlling an electrical switch device and can be mounted on a cabinet in which is placed the electrical switch device. In this case, the transmission axis is secured to a rotating movable member of the electrical switch device.

D'autres caractéristiques et avantages vont apparaître dans la description détaillée qui suit en se référant à un mode de réalisation donné à titre d'exemple et représenté par les dessins annexés sur lesquels :

  • La figure 1 représente schématiquement suivant une coupe axiale le dispositif d'actionnement selon l'invention.
  • Les figures 2A et 2B représentent de manière schématique le fonctionnement de l'invention. La figure 2A représente l'état de la manette en marche normale tandis que la figure 2B représente la mise en oeuvre des moyens de blocage de la rotation de la manette lorsque les contacts de l'appareil électrique interrupteur sont soudés.
  • La figure 3 représente de manière schématique le fonctionnement d'une variante des moyens de blocage de la rotation de la manette.
Other features and advantages will appear in the detailed description which follows with reference to an embodiment given by way of example and represented by the appended drawings in which:
  • Figure 1 shows schematically in axial section the actuating device according to the invention.
  • Figures 2A and 2B show schematically the operation of the invention. FIG. 2A shows the state of the joystick in normal operation whereas FIG. 2B shows the implementation of the means for blocking the rotation of the handle when the contacts of the electrical switch device are soldered.
  • Figure 3 schematically shows the operation of a variant of the locking means of the rotation of the joystick.

Le dispositif d'actionnement 1 selon l'invention est par exemple déporté par rapport à l'appareil électrique interrupteur et monté sur la porte d'une armoire électrique afin de permettre à l'opérateur de manipuler l'appareil électrique sans ouvrir l'armoire électrique. Une telle armoire ne peut être ouverte que si le dispositif d'actionnement 1 se trouve dans une position "Arrêt" (ARRET sur les figures 2A, 2B et 3). De tels dispositifs d'actionnement sont bien connus de l'art antérieur et sont par exemple utilisés pour la commande déportée de disjoncteur.The actuating device 1 according to the invention is for example remote from the electrical switch device and mounted on the door of an electrical cabinet to allow the operator to manipulate the electrical device without opening the cabinet electric. Such a cabinet can be opened only if the actuating device 1 is in a "stop" position (OFF in FIGS. 2A, 2B and 3). Such actuating devices are well known in the prior art and are for example used for the remote control circuit breaker.

En référence à la figure 1, un dispositif d'actionnement 1 déporté selon l'invention comporte un corps 10 sur lequel est montée une manette 2 rotative dont le mouvement de rotation autour d'un axe principal (A) est solidaire de celui d'un axe de transmission 3 chargé de transmettre le mouvement de la manette 2 à un organe rotatif de l'appareil électrique interrupteur présent dans l'armoire, ledit organe rotatif de l'appareil électrique commandant l'ouverture ou la fermeture des contacts électriques dans l'appareil électrique interrupteur. L'axe de transmission 3 est solidaire d'un support d'axe 4 ayant la forme d'un chapeau composé d'un capuchon 40 recevant la tête 30 de l'axe de transmission 3, étendu vers l'extérieur d'une plaque annulaire 41. Le support d'axe 4 est disposé de manière coaxiale par rapport à l'axe de transmission 3. Un roulement à billes 5 est positionné coaxialement entre le corps 10 et le support d'axe 4 pour permettre la rotation de l'axe de transmission 3 par rapport au corps 10.Referring to Figure 1, a remote actuating device 1 according to the invention comprises a body 10 on which is mounted a rotary lever 2 whose rotational movement about a main axis (A) is integral with that of a transmission axis 3 responsible for transmitting the movement of the lever 2 to a rotary member of the electrical switch device present in the cabinet, said rotary member of the electrical apparatus controlling the opening or closing of the electrical contacts in the electrical appliance switch. The transmission shaft 3 is integral with an axle support 4 having the shape of a cap composed of a cap 40 receiving the head 30 of the transmission shaft 3, extended towards the outside of a plate The shaft support 4 is arranged coaxially with respect to the transmission axis 3. A ball bearing 5 is positioned coaxially between the body 10 and the axis support 4 to allow the rotation of the shaft. transmission axis 3 with respect to the body 10.

Le support d'axe 4 est solidaire en rotation de la manette 2 par l'intermédiaire de moyens de liaison élastiques, tels que par exemple une lame ressort 6. En fonctionnement normal, la lame ressort 6 est chargée de transmettre au support d'axe 4, et donc à l'axe de transmission 3, le mouvement de rotation imprimé à la manette 2 par l'opérateur ou en cas de disjonction le mouvement de rotation de l'axe de transmission 3 à la manette 2.The axis support 4 is integral in rotation with the lever 2 by means of elastic connection means, such as for example a spring blade 6. In normal operation, the spring blade 6 is responsible for transmitting to the axis support 4, and therefore to the transmission axis 3, the rotational movement printed on the lever 2 by the operator or in case of disjunction the rotational movement of the transmission shaft 3 to the lever 2.

La lame ressort 6 est d'une flexibilité suffisante pour, en fonctionnement normal, solidariser en rotation la manette 2 et le support d'axe 4 et pour, lorsque le support d'axe est immobilisé dû à une soudure entre les contacts, fléchir lorsqu'un couple de rotation est exercé sur la manette 2.The spring blade 6 is of sufficient flexibility for, in normal operation, to rotate the lever 2 and the axle support 4 in rotation and, when the axle support is immobilized due to a weld between the contacts, to bend when a torque is exerted on the handle 2.

La lame ressort 6 est par exemple disposée suivant un plan axial du dispositif 1 et présente par exemple une forme trapézoïdale afin de mieux répartir les efforts sur sa longueur lorsqu'elle fléchit. La petite base de la lame ressort 6 est par exemple reliée à la manette 2 tandis que la grande base est reliée au support d'axe 4.The spring blade 6 is for example arranged in an axial plane of the device 1 and has for example a trapezoidal shape to better distribute the forces along its length when it flexes. The small base of the spring blade 6 is for example connected to the handle 2 while the large base is connected to the axis support 4.

Le support d'axe 4 comporte en outre un plot 42 se dressant sur sa plaque annulaire 41 suivant un axe parallèle à l'axe principal (A), traversant le corps 10 et formant un axe sur lequel est monté un organe de blocage 7, 7a, 7b. Lors de la rotation de l'axe de transmission 3 et donc du support d'axe 4, le plot 42 suit une rainure 12 formée à travers le corps 10.The axis support 4 further comprises a stud 42 standing on its annular plate 41 along an axis parallel to the main axis (A), passing through the body 10 and forming an axis on which a locking member 7 is mounted, 7a, 7b. During the rotation of the transmission axis 3 and thus of the axis support 4, the stud 42 follows a groove 12 formed through the body 10.

Selon un premier mode de réalisation représenté sur les figures 2A et 2B, l'organe de blocage 7a est constitué d'un levier monté en rotation sur le plot 42 et susceptible de pivoter suivant un plan perpendiculaire à l'axe principal (A) entre une position de repos et une position de travail.According to a first embodiment shown in Figures 2A and 2B, the locking member 7a consists of a lever rotatably mounted on the stud 42 and pivotable in a plane perpendicular to the main axis (A) between a rest position and a working position.

L'organe de blocage 7a comporte un creux dans lequel est engagée une partie de la manette 2 par exemple une protubérance 20 formée sur celle-ci. Le creux définit une came 70a sur laquelle s'appuie la protubérance 20 pour faire pivoter l'organe de blocage 7a autour de son axe lorsque les contacts sont soudés et donc lorsque l'axe de transmission et le support d'axe sont immobilisés. La rotation de la manette 2 entraîne donc le pivotement de l'organe de blocage 7a jusqu'à ce que celui-ci vienne dans sa position de travail, en appui contre le corps 10 du dispositif 1. La rotation de la manette 2 dans un sens allant de sa position "Marche" (MARCHE) vers sa position "Arrêt" (ARRET) entraîne un pivotement de l'organe de blocage 7a dans le sens opposé.The locking member 7a has a recess in which is engaged a portion of the handle 2, for example a protuberance 20 formed thereon. The recess defines a cam 70a on which the protuberance 20 rests to pivot the locking member 7a about its axis when the contacts are welded and therefore when the transmission axis and the axis support are immobilized. The rotation of the handle 2 therefore causes the locking member 7a to pivot until it comes into its working position, bearing against the body 10 of the device 1. The rotation of the handle 2 in a direction from its "ON" position (ON) to its "OFF" position (OFF) causes a pivoting of the locking member 7a in the opposite direction.

L'organe de blocage 7a comporte en outre des dents 71 a pour s'accrocher sur des dents 11 correspondantes formées sur le corps 10 du dispositif 1 lorsqu'il est en appui contre le corps 10.The blocking member 7a further comprises teeth 71a for catching on corresponding teeth 11 formed on the body 10 of the device 1 when it bears against the body 10.

En fonctionnement normal, la rotation de la manette 2 entre ses positions "Marche" (MARCHE) et "Arrêt" (ARRET) s'accompagne d'une rotation de l'axe de transmission 3 et du support d'axe 4 portant l'organe de blocage 7a, la transmission du mouvement étant réalisée par l'intermédiaire de la lame ressort 6. L'écart angulaire entre la manette 2 et l'ensemble support d'axe 4/axe de transmission 3 est alors nul.In normal operation, the rotation of the handle 2 between its "ON" and "OFF" positions (OFF) is accompanied by a rotation of the transmission shaft 3 and the axis support 4 carrying the blocking member 7a, the transmission of the movement being performed by means of the spring blade 6. The angular distance between the handle 2 and the support assembly axis 4 / transmission axis 3 is then zero.

Lorsque les contacts sont soudés entre eux à la suite par exemple d'un court circuit, l'axe de transmission 3, le support d'axe 4 et donc l'organe de blocage 7a se trouvent immobilisés et la manette 2 est donc dans sa position "Marche" (MARCHE). L'exercice d'un couple rotatif sur la manette 2 pour la ramener vers sa position "Arrêt" (ARRET) entraîne une flexion de la lame ressort 6 et donc une rotation d'un certain angle de la manette 2 par rapport au support d'axe 4. L'écart angulaire entre la manette 2 et l'ensemble support d'axe 4/axe de transmission 3 augmente sous l'exercice de ce couple de rotation. En tournant la manette 2 par rapport au support d'axe 4 et en augmentant l'écart angulaire, la protubérance 20 s'appuie contre la came 70a de l'organe de blocage 7a amorçant le pivotement de l'organe de blocage 7a dans le sens opposé à celui de la rotation de la manette 2. Lorsque l'écart angulaire entre la manette 2 et l'ensemble support d'axe 4/axe de transmission 3 dépasse un seuil déterminé, l'organe de blocage 7a, en pivotant, prend sa position de travail et vient donc en appui contre le corps 10 du dispositif 1, ses dents 71a coopérant avec les dents 11 correspondantes du corps 10 (figure 2B). Au-delà de ce seuil, la rotation de la manette 2 par rapport au corps 10 est impossible, la protubérance 20 de la manette 2 venant alors en butée contre l'organe de blocage 7a (figure 2B).When the contacts are welded together following for example a short circuit, the transmission axis 3, the axis support 4 and therefore the locking member 7a are immobilized and the lever 2 is in its place. "ON" position. The exercise of a rotary torque on the handle 2 to bring it back to its "OFF" position causes the spring blade 6 to bend and thus to rotate at a certain angle of the handle 2 relative to the support 4. The angular difference between the handle 2 and the support assembly axis 4 / transmission axis 3 increases under the exercise of this torque. Turning the knob 2 relative to the bracket of axis 4 and increasing the angular difference, the protrusion 20 rests against the cam 70a of the locking member 7a initiating the pivoting of the locking member 7a in the opposite direction to that of the rotation of the 2. When the angular difference between the handle 2 and the axis support assembly 4 / transmission axis 3 exceeds a determined threshold, the locking member 7a, by pivoting, takes its working position and therefore comes into bearing against the body 10 of the device 1, its teeth 71a cooperating with the corresponding teeth 11 of the body 10 (Figure 2B). Beyond this threshold, the rotation of the handle 2 relative to the body 10 is impossible, the protrusion 20 of the handle 2 then abuts against the locking member 7a (Figure 2B).

Selon un second mode de réalisation représenté en figure 3, l'organe de blocage 7b est monté en rotation sur le plot 42 et a la forme d'un papillon présentant deux ailes symétriques par rapport au plan axial passant par son axe de rotation, formant entre elles un creux définissant deux cames 70b, 71 b symétriques. Une partie de la manette 2, par exemple une protubérance 20 formée sur celle-ci, est engagée dans le creux de l'organe de blocage 7b. Cet organe de blocage 7b comporte en outre deux surfaces d'appui symétriques, chacune formée sur un flanc opposé à une came 70b, 71 b. Ces deux surfaces d'appui sont munies de dents 72b, 73b pouvant coopérer avec des dents 11 correspondantes du corps 10 du dispositif 1.According to a second embodiment shown in FIG. 3, the locking member 7b is rotatably mounted on the stud 42 and has the shape of a butterfly having two wings symmetrical with respect to the axial plane passing through its axis of rotation, forming between them a hollow defining two cams 70b, 71b symmetrical. A part of the handle 2, for example a protrusion 20 formed on it, is engaged in the hollow of the locking member 7b. This locking member 7b further comprises two symmetrical bearing surfaces, each formed on a side opposite a cam 70b, 71b. These two bearing surfaces are provided with teeth 72b, 73b that can cooperate with corresponding teeth 11 of the body 10 of the device 1.

Le fonctionnement de l'invention avec l'organe de blocage selon ce second mode de réalisation est identique à précédemment.The operation of the invention with the locking member according to this second embodiment is identical to previously.

En fonctionnement normal, la rotation de la manette 2 entraîne une rotation du support d'axe 4 et de l'axe de transmission 3. L'écart angulaire entre la manette 2 et l'ensemble support d'axe 4/axe de transmission 3 est nul.In normal operation, the rotation of the handle 2 causes a rotation of the axis support 4 and the transmission axis 3. The angular difference between the handle 2 and the axis support assembly 4 / transmission axis 3 is zero.

Lorsque les contacts sont soudés entre eux et que l'organe de blocage 7b solidaire du support d'axe 40 est immobilisé, une rotation de la manette 2 dans un sens ou dans l'autre modifie l'écart angulaire entre la manette 2 et l'ensemble support d'axe 4/axe de transmission 3, cette modification étant permise par une flexion dans un sens ou dans l'autre de la lame ressort 6 reliant la manette 2 au support d'axe 4. La protubérance 20 s'engage alors sur l'une des cames 70b, 71 b de l'organe de blocage 7b pour amorcer le pivotement de l'organe de blocage 7b dans le sens opposé à celui de rotation de la manette 2. Lorsque l'écart angulaire entre la manette 2 et l'ensemble support d'axe 4/axe de transmission 3 est supérieur à un seuil déterminé, l'organe de blocage 7b, dans sa position de travail, vient s'appuyer contre le corps 10 du dispositif 1 par l'une de ses surfaces d'appui, ses dents 72b, 73b coopérant avec les dents 11 correspondantes formées sur le corps 10 pour bloquer la rotation de la manette 2. Au-delà de ce seuil, la rotation de la manette 2 par rapport au corps 10 est alors impossible, la protubérance 20 de la manette 2 venant en butée contre l'organe de blocage 7b.When the contacts are welded together and the locking member 7b integral with the axis support 40 is immobilized, a rotation of the handle 2 in one direction or the other changes the angular difference between the handle 2 and the 4) axle support assembly / transmission axis 3, this modification being allowed by a bending in one direction or the other of the spring blade 6 connecting the lever 2 to the axis support 4. The protrusion 20 engages then on one of the cams 70b, 71b of the locking member 7b to initiate the pivoting of the locking member 7b in the opposite direction to that of rotation of the handle 2. When the angular distance between the joystick 2 and the shaft support assembly 4 / transmission axis 3 is greater than a determined threshold, the locking member 7b, in its working position, bears against the body 10 of the device 1 by one of its bearing surfaces, its teeth 72b, 73b cooperating with the corresponding teeth 11 formed on the body 10 to block the rotation of the handle 2. Beyond this threshold, the rotation of the handle 2 relative to the body 10 is then impossible, the protrusion 20 of the handle 2 abuts against the locking member 7b.

Dans ce second mode de réalisation, grâce à ses deux cames 70b, 71 b symétriques, l'organe de blocage 7b présente l'avantage de pouvoir être actionné en pivotement dans un sens ou dans l'autre selon le sens de la rotation forcée de la manette 2.In this second embodiment, thanks to its two cams 70b, 71b symmetrical, the locking member 7b has the advantage of being able to be pivotally actuated in one direction or the other in the direction of the forced rotation of the joystick 2.

Selon l'invention, le retour de l'organe de blocage 7, 7a, 7b de sa position de travail vers sa position de repos est par exemple réalisé naturellement lors du retour de la manette 2 en position "Marche" (MARCHE), la protubérance 20 de celle-ci suivant la came en sens inverse jusqu'à ce que l'écart angulaire entre la manette 2 et l'ensemble support d'axe 4/axe de transmission 3 revienne à une valeur proche de zéro. Selon une variante de réalisation, l'organe de blocage 7, 7a, 7b peut également être montée sur un ressort de rappel (non représenté) pour être ramené en position de repos.According to the invention, the return of the blocking member 7, 7a, 7b from its working position to its rest position is, for example, achieved naturally when the lever 2 is returned to the "ON" position (ON). protuberance 20 thereof along the cam in the opposite direction until the angular spacing between the handle 2 and the shaft support assembly 4 / transmission axis 3 returns to a value close to zero. According to an alternative embodiment, the locking member 7, 7a, 7b can also be mounted on a return spring (not shown) to be returned to the rest position.

Le dispositif d'actionnement 1 comporte en outre un dispositif de verrouillage monté sur la manette 2 et permettant de verrouiller la rotation de la manette 2 lorsque celle-ci est dans sa position "Arrêt" (ARRET). Pour des raisons de sécurité, le verrouillage de la manette 2 ne doit être possible que lorsque la manette 2 est dans sa position "Arrêt" (ARRET). Pour cela, le dispositif de verrouillage comporte un élément coulissant 23 solidaire de la manette 2 et extractible de celle-ci et un organe 21 de verrouillage, tous deux mobiles en translation suivant l'axe principal (A) entre une position de déverrouillage et une position de verrouillage de la rotation de la manette 2. L'organe 21 de verrouillage comporte par exemple une tige 210 apte à traverser un orifice 100 du corps et un orifice 43 du support d'axe 4 pour bloquer la manette 2 en rotation lorsqu'elle se trouve dans sa position "Arrêt" (ARRET).The actuating device 1 further comprises a locking device mounted on the handle 2 and for locking the rotation of the handle 2 when it is in its "OFF" position. For safety reasons, the locking of the handle 2 should only be possible when the handle 2 is in its "OFF" position. For this, the locking device comprises a sliding element 23 integral with the lever 2 and extractable thereof and a locking member 21, both movable in translation along the main axis (A) between an unlocking position and a locking position of the rotation of the handle 2. The locking member 21 comprises for example a rod 210 adapted to pass through a hole 100 of the body and an orifice 43 of the axis support 4 to lock the handle 2 in rotation when it is in the "OFF" position.

L'élément coulissant 23 est doté d'une ouverture 24, par exemple de forme oblongue, par laquelle il est possible de faire passer des cadenas afin d'empêcher le retour de l'élément coulissant 23 dans son logement et donc de verrouiller le dispositif d'actionnement 1. Cet élément coulissant 23 est mobile en translation suivant l'axe principal (A). Le mouvement de translation de l'organe de verrouillage 21 s'accompagne d'un mouvement correspondant de l'élément coulissant 23 en utilisant un mécanisme d'entraînement monté sur la manette 2. Ce mécanisme d'entraînement constitué d'une biellette 22 permet de transformer le mouvement de translation de l'organe de verrouillage 21 suivant l'axe principal (A) et dans un sens déterminé, en un mouvement de translation de l'élément coulissant 23 suivant l'axe principal (A) et dans le sens opposé à celui de l'organe de verrouillage 21. Lorsque la manette 2 est dans sa position "Arrêt", une pression sur un bouton 211 de l'organe de verrouillage 21 entraîne donc une extraction de l'élément coulissant 23.The sliding element 23 is provided with an opening 24, for example of oblong shape, through which it is possible to pass padlocks to prevent the return of the sliding element 23 in its housing and thus to lock the device This sliding element 23 is movable in translation along the axis principal (A). The translational movement of the locking member 21 is accompanied by a corresponding movement of the sliding member 23 by using a drive mechanism mounted on the handle 2. This driving mechanism consists of a rod 22 allows to transform the translation movement of the locking member 21 along the main axis (A) and in a given direction, into a translation movement of the sliding element 23 along the main axis (A) and in the direction opposite to that of the locking member 21. When the handle 2 is in its "Off" position, pressing a button 211 of the locking member 21 thus causes extraction of the sliding element 23.

Il est bien entendu que l'on peut, sans sortir du cadre de l'invention, imaginer d'autres variantes et perfectionnements de détail et de même envisager l'emploi de moyens équivalents.It is understood that one can, without departing from the scope of the invention, imagine other variants and refinements of detail and even consider the use of equivalent means.
