Description

Domaine technique de l'inventionTechnical field of the invention

La présente invention se rapporte à un dispositif d'arrêt d'urgence, présentant notamment une architecture et une étanchéité améliorée.The present invention relates to an emergency stop device, in particular having improved architecture and improved sealing.

Etat de la techniqueState of the art

Aujourd'hui, un dispositif d'arrêt d'urgence connu tel que décrit par exemple dans le document US7790996 comporte un bouton de commande mobile en translation entre deux positions suivant un axe de commande et susceptible d'actionner un poussoir coopérant avec une unité de contact électrique. Pour déverrouiller de tels dispositifs d'arrêt d'urgence, le bouton de commande est actionné en rotation. Pour pouvoir être aisément manipulée, le bouton doit présenter une forme lui permettant d'être facilement préhensible par rapport au reste du dispositif. Il prend donc souvent une forme particulièrement saillante, ce qui augmente son encombrement en profondeur.Today, a known emergency stop device as described for example in the document US7790996 comprises a control button movable in translation between two positions along a control axis and capable of actuating a pusher cooperating with an electrical contact unit. To unlock such emergency stop devices, the control knob is rotated. To be easily manipulated, the button must have a shape that allows it to be easily gripped relative to the rest of the device. It therefore often takes a particularly prominent shape, which increases its size in depth.

La demande de brevet FR2792453A1 décrit une solution classique de dispositif d'arrêt d'urgence.The patent application FR2792453A1 describes a conventional solution of emergency stop device.

Le brevet EP2700080B1 décrit pour sa part un dispositif d'arrêt d'urgence plus compact. Dans cette solution, la fonction de déverrouillage est assurée par une bague rotative, indépendante du bouton. La rotation de la bague sert à initier le déverrouillage pour faire revenir le bouton d'actionnement en position initiale de repos. Le retour en position initiale est ensuite assuré par le ressort (R1 dans ce document) qui est aussi employé pour réaliser le déclenchement du dispositif. La fonction de déclenchement du dispositif est en effet assurée par deux ressorts (R1, R2) dont les constantes de raideur sont ajustées l'une par rapport à l'autre. La raideur du ressort principal (R1) doit tenir compte de la raideur de l'autre ressort (R2) et est choisie relativement faible pour donner au dispositif d'arrêt d'urgence la sensibilité souhaitée. Elle ne peut en effet pas être augmentée sans détériorer le fonctionnement global du dispositif. En effet, une augmentation de la raideur du ressort R1, qui serait souhaitable pour mieux assurer le retour du bouton vers sa position initiale de repos, serait cependant préjudiciable au fonctionnement du dispositif lors de la phase de déclenchement. Il en ressort que la solution décrite dans ce brevet EP2700080B1 conserve certains inconvénients.The patent EP2700080B1 describes a more compact emergency stop device. In this solution, the unlocking function is provided by a rotating ring, independent of the button. The rotation of the ring serves to initiate the unlocking to return the actuating button to the initial position of rest. The return to the initial position is then ensured by the spring (R1 in this document) which is also used to trigger the device. The triggering function of the device is indeed provided by two springs (R1, R2) whose stiffness constants are adjusted relative to each other. The stiffness of the main spring (R1) must take into account the stiffness of the other spring (R2) and is chosen relatively low to give the emergency stop device the desired sensitivity. It can not be increased without deteriorating the overall operation of the device. Indeed, an increase in the stiffness of the spring R1, which would be desirable to better ensure the return of the button to its initial rest position, however, would be detrimental to the operation of the device during the triggering phase. It follows that the solution described in this patent EP2700080B1 keeps some disadvantages.

Le but de l'invention est donc de proposer un dispositif d'arrêt d'urgence dans lequel la fonction de déverrouillage pour le retour du bouton de commande vers la position initiale de repos est particulièrement fiable et mise en oeuvre sans préjudice sur la fonction de déclenchement.The object of the invention is therefore to provide an emergency stop device in which the unlocking function for the return of the control button to the initial rest position is particularly reliable and implemented without prejudice to the trigger function.

La solution de l'invention permet également de régler certains autres inconvénients des dispositifs antérieurs, notamment en termes d'étanchéité du dispositif.The solution of the invention also makes it possible to regulate certain other disadvantages of the prior devices, in particular in terms of sealing the device.

Description détaillée d'au moins un mode de réalisationDetailed description of at least one embodiment

De manière connue, un dispositif d'arrêt d'urgence 1 est destiné à la commande d'un circuit électrique et peut être actionné par un opérateur pour ouvrir le circuit électrique en cas d'urgence.In known manner, an emergency stop device 1 is for controlling an electric circuit and can be actuated by an operator to open the electrical circuit in case of emergency.

Le dispositif d'arrêt d'urgence 1 de l'invention pourra être monté à travers une ouverture de diamètre standard (par exemple diamètre 22mm ou 30mm) réalisée dans une paroi ou dans une boîte d'encastrement fixée sur la paroi ou encastrée dans la paroi. De manière classique, une bague de fixation 25 sera par exemple employée pour assurer la fixation du dispositif sur la paroi. On définit le côté avant de la paroi comme le côté duquel le bouton de commande est accessible et le côté arrière de la paroi comme le côté où est placé l'ensemble de contacts électriques.The emergency stop device 1 of the invention may be mounted through an opening of standard diameter (for example diameter 22mm or 30mm) made in a wall or in a mounting box fixed on the wall or embedded in the wall. Typically, an attachment ring 25 will for example be used to ensure the attachment of the device on the wall. The front side of the wall is defined as the side of which the control knob is accessible and the back side of the wall as the side where the set of electrical contacts is placed.

Dans la suite de la description et sur les dessins annexés, nous définissons un axe de commande (X) suivant lequel les parties mobiles du dispositif 1 sont actionnés en translation. Les termes "supérieur", "inférieur", 'haut" ou "bas" sont à comprendre en prenant comme référence l'axe de commande (X) selon une direction verticale.In the remainder of the description and the accompanying drawings, we define a control axis (X) according to which the moving parts of the device 1 are actuated in translation. The terms "upper", "lower", "high" or "low" are to be understood by taking the control axis (X) as a reference in a vertical direction.

Dans la suite de la description, on définit trois positions ou états distincts du dispositif. Ces trois positions s'appliquent à tous les éléments mobiles du dispositif d'arrêt d'urgence décrit ci-dessous. Ces trois positions sont les suivantes :

  • Position de repos dans laquelle les différents éléments mobiles sont à l'état repos, c'est-à-dire avant actionnement du dispositif ;
  • Position actionnée obtenue après un actionnement du dispositif ; L'actionnement est alors réalisé jusqu'à ce que le bouton de commande arrive en butée ;
  • Position actionnée-relâchée obtenue après actionnement du dispositif et relâchement du bouton de commande ; Pour sortir de cette position, le dispositif devra être déverrouillé.
In the remainder of the description, three distinct positions or states of the device are defined. These three positions apply to all moving parts of the emergency stop device described below. These three positions are as follows:
  • Rest position in which the various mobile elements are in the idle state, that is to say before actuation of the device;
  • Actuated position obtained after an actuation of the device; The actuation is then carried out until the control button reaches the stop;
  • Actuated-released position obtained after actuation of the device and release of the control button; To exit this position, the device must be unlocked.

Le dispositif d'arrêt d'urgence de l'invention comporte plusieurs ensembles fonctionnels :

  • Un ensemble de commande ;
  • Un ensemble d'actionnement ;
  • Un ensemble de déverrouillage ;
  • Un ensemble de contacts électriques.

  • The lower part 141 of the inner casing 14 is inserted through the standard opening made in the wall, so that its shoulder bears against the wall, at the periphery of the opening, on the front side of the wall;
  • The fixing ring is positioned on the lower part of the inner casing to lock the attachment of the device to the rear side of the wall.

L'ensemble de commande du dispositif d'arrêt d'urgence comporte un bouton de commande 11, monté en coulissement dans la partie tubulaire 133 du boîtier externe 13 du corps, de manière à pouvoir être actionné en translation par rapport au corps du dispositif selon ledit axe de commande (X). Le bouton de commande 11 est initialement dans une position de repos dans laquelle le circuit électrique commandé est fermé. Par pression vers l'intérieur du dispositif, le bouton de commande 11 est coulissé dans la partie tubulaire 133 pour être amené dans une position actionnée dans laquelle il vient en butée contre le corps du dispositif, permettant alors d'ouvrir de manière positive le circuit électrique. Après actionnement, le bouton de commande 11 est relâché mais reste alors accroché dans une position dite actionnée-relâchée, dans laquelle le circuit électrique reste ouvert. Le circuit électrique reste ouvert jusqu'à ce que le dispositif soit déverrouillé.The control assembly of the emergency stop device comprises a control knob 11, slidably mounted in the tubular portion 133 of the outer casing 13 of the body, so as to be actuable in translation relative to the body of the device according to said control axis (X). The control knob 11 is initially in a rest position in which the controlled electric circuit is closed. By pressing inside the device, the control knob 11 is slid into the tubular portion 133 to be brought into an actuated position in which it abuts against the body of the device, thereby allowing the circuit to be positively opened. electric. After actuation, the control button 11 is released but then remains hooked in a so-called actuated-relaxed position, in which the electrical circuit remains open. The electrical circuit remains open until the device is unlocked.

Le bouton de commande 11 comporte avantageusement une tête 111 sur laquelle une pression peut être appliquée pour actionner le dispositif et une queue 112 s'étendant dans une direction axiale vers l'intérieur du dispositif et destinée à coopérer avec l'ensemble d'actionnement du dispositif. La tête du dispositif comporte avantageusement une section de forme non circulaire, lui permettant de coopérer en rotation avec la bague de déverrouillage 20.The control knob 11 advantageously comprises a head 111 on which a pressure can be applied to actuate the device and a shank 112 extending in an axial direction towards the inside of the device and intended to cooperate with the actuating assembly of the device. device. The head of the device advantageously comprises a section of non-circular shape, enabling it to cooperate in rotation with the unlocking ring 20.

En référence aux figures 3A et 3B, l'ensemble d'actionnement comporte un poussoir d'actionnement 12 accroché au bouton de commande 11 par l'intermédiaire d'organes de fixation réalisés à la fois sur le bouton de commande 11 et le poussoir d'actionnement. Ces organes de fixation sont par exemple des organes d'encliquetage, permettant d'assurer l'encliquetage du poussoir d'actionnement sur la queue 112 du bouton de commande 11.With reference to Figures 3A and 3B , the actuating assembly comprises an actuating pusher 12 hooked to the control button 11 by means of fixing members made both on the control button 11 and the actuating pusher. These fixing members are, for example, latching members, making it possible to snap the actuating pusher onto the tail 112 of the control knob 11.

Le poussoir d'actionnement 12 est monté coulissant dans la collerette du boîtier interne 14. Le poussoir d'actionnement 12 se présente sous la forme d'une pièce cylindrique comprenant un manchon interne 120 et un manchon externe 121 formant entre eux une cuvette 122. Le poussoir d'actionnement 12 comporte également une collerette 123 réalisée sur son manchon externe.The actuating pusher 12 is slidably mounted in the flange of the inner casing 14. The actuating pusher 12 is in the form of a cylindrical piece comprising an inner sleeve 120 and an outer sleeve 121 forming between them a bowl 122. The actuating pusher 12 also has a flange 123 made on its outer sleeve.

L'ensemble d'actionnement comporte un ressort d'actionnement R1 venant prendre appui d'une part contre le fond de la cuvette 143 du boîtier interne et d'autre part contre la collerette 123 du poussoir d'actionnement 12, de sorte que le poussoir 12 d'actionnement soit monté sur ce ressort d'actionnement R1.The actuating assembly comprises an actuating spring R1 bearing on the one hand against the bottom of the bowl 143 of the inner casing and on the other hand against the flange 123 of the actuating pusher 12, so that the actuating pusher 12 is mounted on this actuating spring R1.

L'ensemble d'actionnement comporte également un poussoir de déclenchement 15. Ce poussoir de déclenchement 15 se présente sous la forme d'une douille qui est accrochée au poussoir d'actionnement 12 tout en conservant un degré de liberté en translation dans la direction axiale par rapport au poussoir d'actionnement 12 entre deux positions de butée. L'ensemble d'actionnement comporte un ressort de déclenchement R2 venant prendre appui d'une part au fond de la cuvette 122 du poussoir d'actionnement 12 et d'autre part dans le fond 150 de la douille formée par le poussoir de déclenchement 15.The actuating assembly also comprises a triggering pusher 15. This triggering pusher 15 is in the form of a socket which is attached to the actuating pusher 12 while maintaining a degree of freedom in translation in the axial direction. relative to the actuating pusher 12 between two stop positions. The actuating assembly comprises a trigger spring R2 bearing firstly at the bottom of the bowl 122 of the actuating pusher 12 and secondly in the bottom 150 of the sleeve formed by the triggering pusher 15 .

L'ensemble d'actionnement comporte également un organe de déclenchement 16 et un organe d'accrochage 17 par exemple composés chacun d'un doigt venant se loger dans un logement radial réalisé sur le poussoir de déclenchement 15. Chacun de ces deux organes est monté sur un ressort hélicoïdal R3, R4 distinct de manière à pouvoir se déplacer de manière radiale par rapport à l'axe de commande (X). L'organe de déclenchement 16 et l'organe d'accrochage 17 sont positionnés de manière à coopérer chacun avec le boîtier interne selon la position du poussoir de déclenchement 15. L'organe de déclenchement 16 et l'organe d'accrochage 17 sont susceptibles de se déplacer suivant deux plans parallèles distincts, perpendiculaires à l'axe de commande (X). Le plan de translation de l'organe de déclenchement 16 est situé au-dessus du plan de translation de l'organe d'accrochage 17. Sur la surface interne de son ouverture centrale, boîtier interne comporte des formes de cames destinées à être suivies par l'organe de déclenchement 16 et l'organe d'accrochage 17, permettant à chacun de ces organes de remplir leur fonction.The actuating assembly also comprises a triggering member 16 and an attachment member 17, for example each consisting of a finger which is housed in a radial housing formed on the triggering pusher 15. Each of these two members is mounted on a helical spring R3, R4 distinct so as to be able to move radially with respect to the control axis (X). The triggering member 16 and the hooking member 17 are positioned so as to cooperate each with the inner casing according to the position of the triggering pusher 15. The triggering member 16 and the attachment member 17 are susceptible to move in two distinct parallel planes, perpendicular to the control axis (X). The plane of translation of the release member 16 is situated above the plane of translation of the fastening member 17. On the inner surface of its central opening, the inner casing comprises cam shapes intended to be followed by the trigger member 16 and the attachment member 17, allowing each of these organs to perform their function.

L'organe de déclenchement 16 est en butée contre une butée 144 du boîtier interne pour verrouiller le déplacement du poussoir de déclenchement 15 vers le bas et le maintenir en position de repos jusqu'à ce qu'une énergie suffisante soit emmagasinée dans le ressort d'actionnement R1. Lorsque le bouton de commande 11 est suffisamment enfoncé, sous l'action d'une forme de came réalisée sur le corps, l'organe de déclenchement 16 s'escamote dans son logement, déverrouillant le poussoir de déclenchement 15. Sous l'action du ressort de déclenchement R2, le poussoir de déclenchement 15 est entraîné en translation vers le bas. Après déclenchement, par les liaisons mécaniques existant à la fois entre, d'une part, le poussoir de déclenchement 15 et le poussoir d'actionnement 12 et, d'autre part, entre le poussoir d'actionnement 12 et le bouton de commande 11, le bouton de commande 11 est maintenu en position actionnée-relâchée vers l'intérieur du corps. L'organe d'accrochage 17 coopère avec une butée 145 réalisée sur le boîtier interne pour permettre d'accrocher le poussoir de déclenchement 15 au corps lorsque le bouton de commande 11 est enfoncé dans sa position actionnée et ainsi de maintenir/verrouiller le poussoir d'actionnement 12 et le bouton de commande 11 dans la position actionnée-relâchée.The triggering member 16 abuts against a stop 144 of the inner casing to lock the movement of the triggering pusher 15 downwards and hold it in the rest position until sufficient energy is stored in the spring of the casing. R1 actuation. When the command button 11 is sufficiently depressed, under the action of a cam formed on the body, the trigger member 16 retracts into its housing, unlocking the trigger pushbutton 15. Under the action of the trigger spring R2, the pusher trigger 15 is driven in translation downwards. After triggering, by the mechanical links existing between both, on the one hand, the triggering pushbutton 15 and the actuating pusher 12 and, on the other hand, between the actuating pusher 12 and the control button 11 the control knob 11 is held in the actuated-released position towards the inside of the body. The hooking member 17 cooperates with an abutment 145 made on the inner casing to allow the triggering pusher 15 to be hooked to the body when the control knob 11 is depressed into its actuated position and thus to hold / lock the pusher. 12 and the control knob 11 in the actuated-released position.

L'ensemble de contacts électriques comporte avantageusement au moins une unité de contact électrique 18, généralement au moins deux unités de contact électrique pour assurer une redondance lors de l'actionnement du dispositif. Chaque unité de contact électrique 18 comporte un jeu de contacts électriques normalement fermé (contacts NC pour "Normally Closed"). Chaque unité de contact 18 comporte par exemple un poussoir 180 solidaire d'un pont de contacts mobiles destiné à être actionné de manière axiale par la queue du poussoir de déclenchement. Les unités de contact sont par exemple fixées sur une embase 19 assemblée sur le corps du dispositif, plus précisément directement sur la partie basse 141 du boîtier interne. Ces caractéristiques étant classiques dans le domaine de la boutonnerie industrielle, elles ne sont pas décrites dans la présente demande de brevet.The set of electrical contacts advantageously comprises at least one electrical contact unit 18, generally at least two electrical contact units to ensure redundancy during actuation of the device. Each electrical contact unit 18 has a normally closed set of electrical contacts (NC contacts for "Normally Closed"). Each contact unit 18 comprises for example a pusher 180 integral with a movable contact bridge intended to be actuated axially by the tail of the triggering pusher. The contact units are for example fixed on a base 19 assembled on the body of the device, more specifically directly on the lower part 141 of the inner housing. These characteristics being conventional in the field of industrial buttoning, they are not described in the present patent application.

L'ensemble de déverrouillage comporte une bague de déverrouillage 20 distincte du bouton de commande 11, qui est montée mobile en rotation sur le boîtier externe 13 du corps, plus précisément sur la partie tubulaire 133 du capot du boîtier externe. La bague de déverrouillage 20 est agencée en périphérie du bouton de commande 11 et coopère en rotation avec le bouton de commande 11 pour le déverrouiller. Des moyens d'entraînement sont agencés entre la bague et le bouton de commande pour assurer l'entraînement du bouton de commande 11 par la bague de déverrouillage 20 lorsque la bague est actionnée en rotation. Ces moyens d'entraînement sont par exemple réalisés par la forme extérieure de la section du bouton de commande 11 et la forme interne de la section de la bague de déverrouillage 20. Sur les figures annexées, le bouton de commande présente une section sensiblement carrée (arrondie à ses sommets) et la bague présente une section dont la forme intérieure vient épouser le contour résultant de cette forme carrée.The unlocking assembly comprises an unlocking ring 20 separate from the control button 11, which is rotatably mounted on the outer casing 13 of the body, more precisely on the tubular portion 133 of the outer casing cover. The unlocking ring 20 is arranged at the periphery of the control knob 11 and cooperates in rotation with the control knob 11 to unlock it. Driving means are arranged between the ring and the control knob to drive the control knob 11 by the unlocking ring 20 when the ring is actuated in rotation. These drive means are for example made by the outer shape of the section of the control knob 11 and the internal shape of the section of the unlocking ring 20. In the accompanying figures, the control knob has a substantially square section (Rounded at its vertices) and the ring has a section whose inner shape comes to marry the contour resulting from this square shape.

Selon un aspect particulier de l'invention, en plus du ressort d'actionnement R1 et du ressort de déclenchement R2, l'ensemble de déverrouillage comporte un ressort R5 spécifique agencé pour entraîner le bouton de commande vers sa position initiale de repos. Ce ressort de déverrouillage R5 est avantageusement logé dans le boîtier externe 13 du corps et est guidé par la paroi formée de la collerette située en partie haute du boîtier interne. Il présente une extrémité attachée au bouton de commande 11 et une autre extrémité attachée au fond du boîtier externe 13. Il est avantageusement précontraint entre ses deux extrémités, en translation dans la direction axiale et en torsion autour de cette direction axiale de manière à assurer également le retour de la bague vers sa position initiale après rotation.According to a particular aspect of the invention, in addition to the actuating spring R1 and the trigger spring R2, the unlocking assembly comprises a specific spring R5 arranged to drive the control button to its initial rest position. This unlocking spring R5 is advantageously housed in the outer casing 13 of the body and is guided by the wall formed of the flange located in the upper part of the inner casing. It has one end attached to the control button 11 and another end attached to the bottom of the outer casing 13. It is advantageously prestressed between its two ends, in translation in the axial direction and in torsion around this axial direction so as to also ensure the return of the ring to its initial position after rotation.

Lors de la rotation de la bague de déverrouillage 20, celle-ci entraîne en rotation le bouton de commande 11 qui entraîne en rotation le poussoir d'actionnement 12 puis le poussoir de déclenchement. La rotation du poussoir de déclenchement 15 libère l'organe d'accrochage 17 de la butée réalisée sur le corps et permet de libérer le bouton de commande 11, qui, sous l'action du ressort de déverrouillage R5, est alors ramené vers sa position de repos. Le ressort de déverrouillage R5 étant précontraint en torsion et en compression, le retour du bouton de commande 11 vers sa position initiale suit une trajectoire de translation combinée à une rotation.During rotation of the unlocking ring 20, the latter rotates the control knob 11 which rotates the actuating pusher 12 and the triggering pusher. The rotation of the release pusher 15 frees the latching member 17 of the stop made on the body and releases the control knob 11, which, under the action of the unlocking spring R5, is then returned to its position rest. The unlocking spring R5 being prestressed in torsion and compression, the return of the control knob 11 to its initial position follows a translational trajectory combined with a rotation.

L'emploi d'une bague de déverrouillage 20 distincte du bouton de commande 11 permet de pouvoir proposer un dispositif présentant une architecture particulièrement compacte.The use of an unlocking ring 20 separate from the control button 11 makes it possible to propose a device having a particularly compact architecture.

Selon un autre aspect particulièrement avantageux de l'invention, on comprend que les trois ressorts R1, R2, R5 sont montés dans des espaces agencés de manière concentrique autour de l'axe de commande (X). Le ressort R2 est situé au plus près de l'axe de commande, le ressort R1 est monté en périphérie du ressort R2 et le ressort R5 est monté en périphérie du ressort R1. Cet agencement permet notamment de gagner en compacité dans le sens de la hauteur.According to another particularly advantageous aspect of the invention, it is understood that the three springs R1, R2, R5 are mounted in spaces arranged concentrically around the control axis (X). The spring R2 is located closer to the control axis, the spring R1 is mounted at the periphery of the spring R2 and the spring R5 is mounted at the periphery of the spring R1. This arrangement allows in particular to gain compactness in the direction of the height.

Bien entendu, les deux ressorts R1 et R2 devront être choisis et adaptés pour assurer un déclenchement du dispositif lorsqu'une certaine pression est exercée sur le bouton de commande. Le ressort R5 sera pour sa part choisi pour assurer le retour du bouton de commande en position initiale, de manière indépendante du choix des deux ressorts R1 et R2. La fonction de déverrouillage sera donc totalement indépendante de la fonction de déclenchement du dispositif.Of course, the two springs R1 and R2 will have to be chosen and adapted to trigger the device when a certain pressure is exerted on the control button. The spring R5 will be selected for the return of the control knob to the initial position, independently of the choice of the two springs R1 and R2. The unlocking function will therefore be totally independent of the triggering function of the device.

Le dispositif d'arrêt d'urgence comporte avantageusement un ensemble lumineux complètement intégré au dispositif, assemblé sur un circuit imprimé 21 logé dans le boîtier externe 13. Cet ensemble lumineux est destiné à assurer une fonction de signalisation lumineuse du dispositif d'arrêt d'urgence. Cet ensemble lumineux comporte par exemple une ou plusieurs diodes électroluminescentes soudées sur le circuit imprimé 21 et connectées à des blocs d'alimentation. L'ensemble lumineux est par exemple commandé pour allumer en jaune ou en rouge le dispositif d'arrêt d'urgence selon l'état de fonctionnement de ce dernier. Le capot 131 du boîtier externe 13 peut présenter une couronne transparente 132 laissant passer la lumière des diodes vers l'extérieur. Cet ensemble lumineux étant logé dans le boîtier externe, son fonctionnement ne vient pas perturber le fonctionnement de l'ensemble d'actionnement. Les blocs d'alimentation des diodes électroluminescentes sont par exemple placés du côté arrière de la paroi et sont reliés aux diodes par des fils passant par exemple par un trou adjacent à l'ouverture de fixation du dispositif ou à travers l'ouverture de fixation du dispositif 1 si celle-ci est de taille adaptée au passage des fils d'alimentation.The emergency stop device advantageously comprises a light assembly completely integrated in the device, assembled on a printed circuit 21 housed in the outer casing 13. This light assembly is intended to provide a light signaling function of the stop device. emergency. This light assembly comprises for example one or more light-emitting diodes soldered on the printed circuit 21 and connected to power supply units. The light assembly is for example controlled to turn yellow or red emergency stop device according to the operating state of the latter. The cover 131 of the outer housing 13 may have a transparent ring 132 passing the light of the diodes outwardly. This luminous assembly being housed in the outer casing, its operation does not disturb the operation of the actuating assembly. The power supply units of the light-emitting diodes are for example placed on the rear side of the wall and are connected to the diodes by wires passing for example through a hole adjacent to the fixing opening of the device or through the fixing opening of the device. device 1 if it is of a size adapted to the passage of the supply son.

Selon un aspect particulièrement avantageux de l'invention, la séparation bien distincte de la fonction d'actionnement et de la fonction de déverrouillage permet de proposer une solution d'étanchéité particulièrement efficace. Le boîtier externe 13 comporte une première solution d'étanchéité et le boîtier interne 14 comporte une deuxième solution d'étanchéité.According to a particularly advantageous aspect of the invention, the separation quite distinct from the actuating function and the unlocking function makes it possible to propose a particularly effective sealing solution. The outer casing 13 comprises a first sealing solution and the inner casing 14 comprises a second sealing solution.

La première solution d'étanchéité comporte notamment un joint à lèvre 22 agencé dans une gorge 110 réalisée sur le flanc latéral du bouton de commande 11. Ce joint à lèvre est destiné à venir frotter contre la paroi interne de la partie tubulaire 133 du capot 131 du boîtier externe 13. Il permet ainsi d'assurer l'étanchéité dans le coulissement du bouton de commande. La présence du ressort de déverrouillage R5 spécifique permet par ailleurs d'assurer le retour du bouton de commande vers sa position de repos, malgré le frottement du joint à lèvre lors du fonctionnement.The first sealing solution comprises in particular a lip seal 22 arranged in a groove 110 formed on the lateral flank of the control knob 11. This lip seal is intended to rub against the inner wall of the tubular portion 133 of the cover 131 of the outer casing 13. It thus ensures sealing in the sliding of the control knob. The presence of the specific unlocking spring R5 also makes it possible to return the control knob to its rest position, despite the friction of the lip seal during operation.
