Description

La présente invention se rapporte à un dispositif d'actionnement pour un appareil électrique interrupteur. 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.The present invention relates to an actuating device for an electrical switch device. 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.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.

Le document US 6,423,912 décrit un tel dispositif d'actionnement dans lequel la manette porte un bouton monté sur ressort masquant les ouvertures lorsqu'elle est en position déverrouillée. Lorsque la manette est en position "Arrêt", une pression du bouton permet d'enclencher le verrouillage de la manette mais également de dégager les ouvertures prévues pour le passage des cadenas.The document US 6,423,912 discloses such an actuating device in which the handle carries a spring-mounted knob concealing the openings when in the unlocked position. When the joystick is in the "Off" position, pressing the button makes it possible to engage the locking of the handle but also to clear the openings provided for the passage of the padlocks.

D'autres dispositifs de verrouillage sont décrits dans les brevets US 3,657,497 , US 4,032,732 ou US 6,596,952 .Other locking devices are described in the patents US 3,657,497 , US 4,032,732 or US 6,596,952 .

Le but de l'invention est de proposer un dispositif d'actionnement d'un appareil électrique qui soit simple d'utilisation, compact et d'un coût réduit.The object of the invention is to provide a device for actuating an electrical device that is easy to use, compact and low cost.

Ce but est atteint par un dispositif d'actionnement pour un appareil électrique interrupteur, comprenant un corps sur lequel est montée une manette rotative et un dispositif de verrouillage de la rotation de la manette qui comprend :

  • un organe de verrouillage mobile en translation suivant un axe principal entre une position de verrouillage de la rotation de la manette et une position de déverrouillage,
  • un élément coulissant monté sur la manette, mobile en translation suivant ledit axe principal et définissant une ouverture pouvant accueillir un ou plusieurs cadenas dans une position de verrouillage,
  • ledit dispositif de verrouillage étant caractérisé en ce qu'il comporte également un mécanisme d'entraînement coopérant d'une part avec l'organe de verrouillage et d'autre part avec l'élément coulissant pour convertir le mouvement de translation de l'un dans un sens déterminé en un mouvement de translation de l'autre dans un sens opposé.
This object is achieved by an actuating device for a switch electrical apparatus, comprising a body on which is mounted a rotary handle and a device for locking the rotation of the handle which comprises:
  • a locking member movable in translation along a main axis between a locking position of the rotation of the handle and an unlocking position,
  • a sliding element mounted on the handle, movable in translation along said main axis and defining an opening for accommodating one or more padlocks in a locking position,
  • said locking device being characterized in that it also comprises a driving mechanism cooperating on the one hand with the body of locking and on the other hand with the sliding element to convert the translational movement of one in a given direction into a translational movement of the other in an opposite direction.

Selon un premier mode de réalisation de l'invention, le mécanisme d'entraînement est constitué d'une biellette présentant une première extrémité solidaire de l'organe de verrouillage et une seconde extrémité solidaire de l'élément coulissant.According to a first embodiment of the invention, the drive mechanism consists of a rod having a first end secured to the locking member and a second end secured to the sliding member.

Selon une particularité de ce premier mode de réalisation, la biellette est montée rotative sur la manette.According to a feature of this first embodiment, the rod is rotatably mounted on the handle.

Selon une autre particularité, l'organe de verrouillage et l'élément coulissant sont chacun montés coulissants respectivement à la première extrémité et à la seconde extrémité de la biellette.According to another feature, the locking member and the sliding member are each slidably mounted respectively at the first end and the second end of the rod.

Selon un second mode de réalisation de l'invention, le mécanisme d'entraînement comporte une roue dentée coopérant avec des dents correspondantes formées d'une part sur l'élément coulissant et d'autre part sur l'organe de verrouillage.According to a second embodiment of the invention, the drive mechanism comprises a gear wheel cooperating with corresponding teeth formed on the one hand on the sliding element and on the other hand on the locking member.

Préférentiellement, l'organe de verrouillage comporte un bouton solidaire en translation de celui-ci, permettant d'actionner le dispositif de verrouillage.Preferably, the locking member comprises a button integral in translation thereof, for actuating the locking device.

Avantageusement, l'organe de verrouillage comporte une tige apte à s'engager, en position de verrouillage, dans un orifice correspondant formé à travers le corps.Advantageously, the locking member comprises a rod adapted to engage, in the locking position, in a corresponding orifice formed through the body.

Avantageusement, un ressort de rappel est monté sur l'organe de verrouillage sollicitant l'organe de verrouillage vers la position de déverrouillage.Advantageously, a return spring is mounted on the locking member urging the locking member to the unlocking position.

Préférentiellement, en position de verrouillage de la manette, l'élément coulissant fait saillie à l'extérieur de la manette et, en position de déverrouillage, il est affleurant de la manette.Preferably, in the locking position of the handle, the sliding element protrudes outside the handle and, in the unlocked position, it is flush with the handle.

Selon une particularité, le dispositif d'actionnement peut comporter un dispositif permettant d'inhiber le dispositif de verrouillage.According to one feature, the actuating device may comprise a device for inhibiting the locking device.

Selon une autre particularité, le dispositif d'actionnement est déporté par rapport à l'appareil électrique interrupteur et la manette coopère avec un axe de transmission solidaire d'un organe mobile rotatif de l'appareil électrique interrupteur.According to another feature, the actuating device is offset relative to the switch electrical apparatus and the handle cooperates with a transmission shaft secured to a rotating movable member of the switch electrical apparatus.

Le dispositif d'actionnement défini ci-dessus est particulièrement adapté pour commander un appareil électrique interrupteur.The actuating device defined above is particularly suitable for controlling an 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 :

  • Les figures 1A et 1B représentent schématiquement le dispositif d'actionnement selon l'invention, présentant un dispositif de verrouillage selon un premier mode de réalisation, respectivement en position de déverrouillage de la manette et en position de verrouillage de la rotation de la manette.
  • Les figures 2A et 2B représentent schématiquement le dispositif d'actionnement selon l'invention disposant d'un dispositif de verrouillage selon un second mode de réalisation, respectivement en position de déverrouillage de la manette et en position de verrouillage 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:
  • FIGS. 1A and 1B schematically represent the actuating device according to the invention, having a locking device according to a first embodiment, respectively in the unlocking position of the handle and in the locking position of the rotation of the handle.
  • FIGS. 2A and 2B schematically represent the actuating device according to the invention having a locking device according to a second embodiment, respectively in the unlocking position of the handle and in the locking position of the rotation of the handle.

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. De tels dispositifs d'actionnement sont bien connus de l'art antérieur et sont par exemple utilisés pour la commande d'un 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 actuating devices are well known in the prior art and are for example used for controlling a circuit breaker.

En référence aux figures 1A à 2B, 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 commandant l'ouverture ou la fermeture de contacts électriques dans l'appareil. La manette 2 est fixée sur un support 30 de l'axe de transmission 3 par exemple à l'aide d'une vis 31, ledit support d'axe 30 étant solidaire de la tête 32 de l'axe de transmission 3 et disposé de manière coaxiale par rapport à l'axe 3. Un roulement à billes 4 est positionné coaxialement entre le corps 10 et le support d'axe 30 pour permettre la rotation de la manette 2 par rapport au corps 10.With reference to FIGS. 1A to 2B, 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 principal axis (A) is integral with that of a transmission axis 3 responsible for transmitting the movement of the handle 2 to a rotary member of the electrical switch device present in the cabinet, said rotary member controlling the opening or closing of electrical contacts in the apparatus. The lever 2 is fixed on a support 30 of the transmission shaft 3, for example by means of a screw 31, the said axle support 30 being integral with the head 32 of the transmission shaft 3 and disposed of coaxial manner with respect to the axis 3. A ball bearing 4 is positioned coaxially between the body 10 and the axis support 30 to allow the rotation of the handle 2 relative to the body 10.

Le support d'axe 30 a la forme d'un chapeau composé d'un capuchon 300 recevant la tête 32 de l'axe de transmission 3, étendu vers l'extérieur d'une plaque annulaire 301.The spindle support 30 has the shape of a cap consisting of a cap 300 receiving the head 32 of the transmission shaft 3, extended outwardly of an annular plate 301.

Selon l'invention, le dispositif d'actionnement 1 comporte 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". 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". Pour cela, le dispositif de verrouillage comporte un élément coulissant 20 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.According to the invention, the actuating device 1 comprises a locking device mounted on the handle 2 and for locking the rotation of the handle 2 when the latter is in its "off" position. For security reasons, the locking of the handle 2 should be possible only when the handle 2 is in its "off" position. For this, the locking device comprises a sliding element 20 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 knob rotation 2.

La manette 2 présente un logement 24 dans lequel est logé l'élément coulissant 20 extractible. L'élément coulissant 20 est doté d'une ouverture 200, par exemple de forme oblongue, par laquelle il est possible de faire passer des cadenas afin d'empêcher le retour de l'élément coulissant 20 dans son logement 22 et donc de verrouiller le dispositif d'actionnement 1. Cet élément coulissant 20 est mobile en translation suivant l'axe principal (A). Selon une variante de réalisation, cette ouverture peut être définie entre l'élément coulissant 20 et la manette 2.The handle 2 has a housing 24 in which is housed the extractable sliding member 20. The sliding element 20 has an opening 200, for example oblong, through which it is possible to pass padlocks to prevent the return of the sliding element 20 in its housing 22 and thus to lock the actuating device 1. This sliding element 20 is movable in translation along the main axis (A). According to an alternative embodiment, this opening can be defined between the sliding element 20 and the lever 2.

En position de déverrouillage (figures 1A et 2A), l'élément coulissant 20 est affleurant de la manette 2 tandis qu'en position de verrouillage (Figures 1 B et 2B) il est saillant par rapport à la manette 2 afin de dégager son ouverture 200 prévue pour recevoir les cadenas.In the unlocking position (FIGS. 1A and 2A), the sliding element 20 is flush with the handle 2 while in the locking position (FIGS. 1B and 2B) it protrudes with respect to the handle 2 in order to disengage its opening 200 provided to receive padlocks.

L'organe de verrouillage 21 comporte une tige 210 apte à se déplacer en translation suivant l'axe principal (A) et destinée à venir traverser un orifice 100 formé à travers le corps 10 du dispositif 1. Cet orifice 100 se trouve en vis-à-vis de la tige 210 uniquement lorsque la manette 2 est dans sa position "Arrêt". Ainsi, la tige 210 ne peut s'engager dans cet orifice 100 pour verrouiller la rotation de la manette 2 que lorsque la manette 2 est dans la position "Arrêt". Un deuxième orifice 302 est également prévu à travers le support d'axe 30, en vis-à-vis de la tige 210. De même un troisième orifice 101 est prévu sur une autre partie du corps 10. Ce troisième orifice 101 est situé en vis-à-vis de la tige 210 uniquement lorsque la manette 2 se trouve dans la position "Arrêt" et est situé dans le même axe que l'orifice 100.The locking member 21 comprises a rod 210 adapted to move in translation along the main axis (A) and intended to pass through an orifice 100 formed through the body 10 of the device 1. This orifice 100 is in contact with only when the handle 2 is in its "off" position. Thus, the rod 210 can engage in this orifice 100 to lock the rotation of the handle 2 when the lever 2 is in the "Off" position. A second port 302 is also provided through the axle holder 30, opposite the rod 210. Likewise a third port 101 is provided on another part of the body 10. This third port 101 is located in vis-à-vis the rod 210 only when the handle 2 is in the "Off" position and is located in the same axis as the orifice 100.

L'organe de verrouillage 21 comporte également un bouton 211 monté sur l'extérieur du dispositif d'actionnement, solidaire en translation de la tige 210 et permettant l'actionnement du dispositif de verrouillage. Lorsque la manette 2 est en position "Arrêt", une pression sur le bouton 211 permet d'enclencher le dispositif de verrouillage et d'engager la tige 210 dans l'orifice 100 du corps 10. L'organe de verrouillage 21, comportant la tige 210 et le bouton 211, est solidaire en rotation de la manette 2.The locking member 21 also comprises a button 211 mounted on the outside of the actuating device, integral in translation with the rod 210 and for actuating the locking device. When the handle 2 is in the "Off" position, pressing the button 211 makes it possible to engage the locking device and to engage the rod 210 in the orifice 100 of the body 10. The locking member 21, comprising the rod 210 and the button 211, is integral in rotation with the handle 2.

Le mouvement de translation de l'organe de verrouillage 21 s'accompagne d'un mouvement correspondant de l'élément coulissant 20 en utilisant un mécanisme d'entraînement (22a, 22b) monté sur la manette 2. Ce mécanisme d'entraînement (22a, 22b) 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 20 suivant l'axe principal (A) et dans le sens opposé à celui de l'organe de verrouillage 21. Une pression sur le bouton 211 de l'organe de verrouillage 21 entraîne donc une extraction de l'élément coulissant 20.The translational movement of the locking member 21 is accompanied by a corresponding movement of the sliding member 20 by using a drive mechanism (22a, 22b) mounted on the handle 2. This drive mechanism (22a , 22b) makes it possible to transform the translational movement of the locking member 21 along the main axis (A) and in a given direction into a translation movement of the sliding element 20 along the main axis (A) and in the opposite direction to that of the locking member 21. A pressure on the button 211 of the locking member 21 thus causes an extraction of the sliding element 20.

L'extraction de l'élément coulissant 20 hors de la manette 2 permet de dégager son ouverture 200 afin de pouvoir y laisser passer des cadenas (non représentés) permettant le verrouillage de la rotation de la manette 2 lorsque celle-ci est dans la position "Arrêt". Si la manette 2 n'est pas dans la position "Arrêt", la tige 210 de l'organe de verrouillage 21 bute contre le corps 10 du dispositif 1 et l'extraction de l'élément coulissant 20 hors de la manette 2 est impossible ou dans tous les cas insuffisante pour pouvoir y insérer les cadenas. Le deuxième orifice 302 prévu à travers le support d'axe 30 et le troisième orifice 101 prévu également à travers le corps 10 permettent uniquement à la tige 210 de poursuivre sa translation lors du verrouillage et donc à l'élément coulissant 20 de s'extraire suffisamment pour pouvoir passer les cadenas à travers l'ouverture 200.The extraction of the sliding element 20 out of the lever 2 makes it possible to disengage its opening 200 in order to be able to pass padlocks (not shown) allowing the locking of the rotation of the lever 2 when the latter is in the position "Stop". If the handle 2 is not in the "Off" position, the rod 210 of the locking member 21 abuts against the body 10 of the device 1 and the extraction of the sliding element 20 out of the handle 2 is impossible or in any case insufficient to be able to insert the padlocks. The second orifice 302 provided through the axle support 30 and the third orifice 101 also provided through the body 10 only allow the rod 210 to continue its translation during locking and thus the sliding member 20 to extract enough to be able to pass the padlocks through the opening 200.

Selon un premier mode de réalisation du dispositif de verrouillage représenté en figures 1A et 2A, le mécanisme d'entraînement est constitué d'une biellette 22a montée rotative sur la manette 2 et présentant une extrémité solidaire de l'élément coulissant 20 et une autre extrémité solidaire de l'organe de verrouillage 21 et plus particulièrement du bouton 211 de celui-ci. La biellette 22a présente par exemple à chacune de ses extrémités deux ouvertures oblongues 220 dans lesquelles sont montés l'élément coulissant 20 et le bouton 211. Lorsque la manette 2 est dans sa position "Arrêt", une pression sur le bouton 211 engage la tige 210 jusque dans l'orifice 100 pour verrouiller la rotation de la manette 2 et entraîne également une rotation de la biellette 22a et un mouvement d'extraction de l'élément coulissant 20 hors de la manette 2 afin de dégager son ouverture 200 prévue pour le passage des cadenas.According to a first embodiment of the locking device represented in FIGS. 1A and 2A, the drive mechanism consists of a link 22a rotatably mounted on the handle 2 and having an end secured to the sliding element 20 and another end integral with the locking member 21 and more particularly the button 211 thereof. The rod 22a has for example at each of its ends two oblong openings 220 in which are mounted the sliding element 20 and the button 211. When the lever 2 is in its "off" position, a pressure on the button 211 engages the rod 210 to the hole 100 to lock the rotation of the handle 2 and also causes a rotation of the link 22a and an extraction movement of the sliding member 20 out of the handle 2 to clear its opening 200 provided for the padlock passage.

Selon un second mode de réalisation du dispositif de verrouillage représenté en figures 1 B et 2B, le mécanisme d'entraînement est constitué d'une roue dentée 22b montée en rotation sur la manette 2 et coopérant avec des dents 220b, 221 b correspondantes formées d'un côté sur l'élément coulissant 20, suivant l'axe principal (A) et de l'autre côté, parallèlement, sur le bouton 211 de l'organe de verrouillage 21. Lorsque la manette 2 est dans la position "Arrêt", une pression sur le bouton 211 pour verrouiller la rotation de la manette 2 engrène les dents 221 b du bouton 211 sur la roue dentée 22b ce qui entraîne la rotation de la roue dentée 22b, celle-ci entraînant, dans le sens opposé à celui de la pression du bouton 211, l'extraction de l'élément coulissant 20 permettant de dégager l'ouverture 200 prévue pour le passage des cadenas.According to a second embodiment of the locking device shown in FIGS. 1B and 2B, the drive mechanism consists of a toothed wheel 22b rotatably mounted on the handle 2 and cooperating with corresponding teeth 220b, 221b formed of one side on the sliding element 20 along the main axis (A) and on the other side parallel to the button 211 of the locking member 21. When the lever 2 is in the "Off" position , pressing the button 211 to lock the rotation of the lever 2 engages the teeth 221b of the button 211 on the toothed wheel 22b which causes the rotation of the toothed wheel 22b, the latter causing, in the opposite direction to that the pressure of the button 211, the extraction of the sliding element 20 to clear the opening 200 provided for the passage of padlocks.

Selon l'invention, l'organe de verrouillage 21 est par exemple monté sur un ressort 23 sollicitant le bouton 211 dans le sens du déverrouillage et donc la rentrée de l'élément coulissant 20 dans son logement 24 prévu sur la manette 2. Le ressort 23 est par exemple de type hélicoïdal et est placé dans un logement de la manette 2 et autour de la tige 210 de l'organe de verrouillage. Le ressort 23 s'appuie à une extrémité contre le bouton 211 et à son autre extrémité contre la manette 2.According to the invention, the locking member 21 is for example mounted on a spring 23 urging the button 211 in the unlocking direction and thus the retraction of the sliding element 20 in its housing 24 provided on the handle 2. The spring 23 is for example helical type and is placed in a housing of the handle 2 and around the rod 210 of the locking member. The spring 23 is supported at one end against the button 211 and at its other end against the handle 2.

Selon l'invention, il est possible de prévoir un dispositif 5 permettant d'inhiber le dispositif de verrouillage. Ce dispositif 5 se compose d'une pièce coulissante, montée sur le corps 10 et accessible de l'extérieur du dispositif d'actionnement 1, venant s'interposer sur le chemin de translation de l'organe de verrouillage 21 en obturant le passage prévu pour la tige 210 (figure 1A). Ainsi la tige 210 ne peut se déployer complètement lors du verrouillage, l'extraction de l'élément coulissant 20 est alors insuffisante pour pouvoir faire passer les cadenas.According to the invention, it is possible to provide a device 5 for inhibiting the locking device. This device 5 consists of a sliding part, mounted on the body 10 and accessible from outside the actuating device 1, coming to be interposed on the translation path of the locking member 21 by closing the passage provided for the rod 210 (Figure 1A). Thus, the rod 210 can not deploy completely during locking, the extraction of the sliding element 20 is then insufficient to be able to pass padlocks.

II est bien entendu que le mécanisme d'entraînement 22a, 22b coopère avec l'organe de verrouillage 21 et avec l'élément coulissant 20 et permet de convertir le mouvement de translation de l'un dans un sens déterminé en un mouvement de translation de l'autre dans le sens opposé. Ainsi, selon une variante de réalisation, l'organe de verrouillage 21 peut être actionné non pas par pression du bouton 211 mais par l'extraction de l'élément coulissant 20.It is understood that the drive mechanism 22a, 22b cooperates with the locking member 21 and with the sliding element 20 and makes it possible to convert the translation movement of the one in a given direction into a translation movement of the other in the opposite direction. Thus, according to an alternative embodiment, the locking member 21 can be actuated not by pressing the button 211 but by extracting the sliding element 20.

II 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.
