Description

La présente invention concerne un dispositif d'actionnement manuel coopérant avec un appareil électrique interrupteur tel qu'un disjoncteur-moteur logé dans un coffret et muni d'un bouton de commande de marche et d'un bouton de commande d'arrêt à mouvements alternés.The present invention relates to a manual actuation device cooperating with an electrical switch device such as a motor circuit breaker housed in a box and fitted with a run control button and a control button stop with alternating movements.

De tels dispositifs de commande sont bien connus et comprennent un bouton marche à impulsion et un bouton d'arrêt d'urgence verrouillable, ces boutons ayant des axes parallèles, étant associés à une paroi du coffret et coopérant respectivement avec les organes marche et arrêt de l'appareil. On constate que, dans certains cas, en dépit du fait que le bouton d'arrêt d'urgence est enfoncé en position arrêt et se trouve verrouillé dans cette position, il est cependant possible de mettre le disjoncteur-moteur à l'état marche en appuyant fortement sur le bouton marche du coffret ; une telle manoeuvre est causée par les déformations et les tolérances qui se manifestent dans le montage.Such control devices are well known and include a impulse start button and a lockable emergency stop button, these buttons having parallel axes, being associated with a wall of the cabinet and cooperating respectively with the device on and off. We note that, in some cases, despite the fact that the emergency stop button is pressed in position stop and is locked in this position, it is however possible to set the motor circuit breaker in the operating state by pressing the on button strongly of the box; such an operation is caused by deformations and tolerances that manifest themselves in the montage.

Le document GB 1 079 012 décrit un appareil interrupteur dont le boítier est muni d'un bouton marche et d'un bouton arrêt qui agissent sur un mécanisme à serrure de déclenchement et de réarmement. Cet appareil ne présente pas de disposition capable d'empêcher, quand l'appareil est logé dans un coffret, l'inconvénient décrit ci-dessus, dû à une cinématique de transmission complexe et aux déformations et tolérances qui altèrent cette cinématique.The document GB 1 079 012 describes a switching device, the housing of which is fitted with an on and off button which act on a mechanism trigger and reset lock. This device has no layout able to prevent, when the device is housed in a cabinet, the inconvenience described above, due to complex transmission kinematics and deformations and tolerances which alter this kinematics.

L'invention a pour but d'éviter cet inconvénient et vise à rendre inopérant l'actionnement du bouton marche du coffret quand le bouton d'arrêt d'urgence du coffret est verrouillé en position arrêt.The invention aims to avoid this drawback and aims to make inoperative actuation of the cabinet on button when the emergency stop button on the cabinet is locked in the off position.

Selon l'invention,

  • le bouton marche à impulsion est relié au bouton marche de l'appareil par l'intermédiaire d'un organe de transmission déclenchable pouvant prendre d'une part un état normal dans lequel est active la transmission au bouton marche d'une impulsion exercée sur le bouton marche à impulsion et d'autre part un état de sécurité dans lequel cette transmission est inactivée,
  • entre le bouton d'arrêt d'urgence et le bouton d'arrêt est disposé un mécanisme de sécurité qui met l'organe de transmission (20) dans son état de sécurité lorsque le bouton d'arrêt d'urgence est enfoncé.
According to the invention,
  • the impulse on button is connected to the on button of the device by means of a triggerable transmission member which can take on the one hand a normal state in which the transmission to the on button of an impulse exerted on the button on impulse and on the other hand a safety state in which this transmission is inactive,
  • between the emergency stop button and the stop button is arranged a safety mechanism which puts the transmission member (20) in its safe state when the emergency stop button is pressed.

Le but visé est donc atteint par des moyens simples, faisant de préférence intervenir pour l'organe de transmission déclenchable un organe à déclenchement brusque, par exemple un levier à genouillère dont le coude est appliqué contre une paroi de glissement prévue sur un levier par ailleurs en appui sur une butée effaçable lorsque le bouton d'arrêt d'urgence est enfoncé.The aim is therefore achieved by simple means, preferably involving for the triggerable transmission member, an abruptly triggered member, for example a toggle lever whose elbow is applied against a wall of sliding provided on a lever otherwise bearing on an erasable stop when the emergency stop button is pressed.

    • Le dispositif d'actionnement 10 illustré sur les figures est associé à un disjoncteur-moteur 11 logé dans un coffret 12 dont la paroi antérieure 13 est munie de boutons-poussoirs d'axes parallèles X1 et X2, à savoir un bouton marche à impulsion 14 et un bouton d'arrêt d'urgence 15 du type dit coup de poing, pour commander, par l'intermédiaire d'éléments de transmission décrits plus loin, un organe de commande marche 16 et un organe de commande arrêt 17 du disjoncteur-moteur 11. Les organes 16,17 sont des boutons sollicités par pression, du type basculant comme décrit dans le document EP-559 507, mais pouvant aussi bien être du type coulissant ; ces organes peuvent prendre deux positions par mouvements alternés, chacun restant maintenu dans l'une ou l'autre position, c'est- à-dire qu'à l'état marche du. disjoncteur-moteur l'organe marche 16 est enfoncé et l'organe arrêt 17 sorti, tandis qu'à l'état arrêt du disjoncteur-moteur l'organe marche 16 est sorti et l'organe arrêt 17 enfoncé.The actuating device 10 illustrated in the figures is associated with a motor circuit breaker 11 housed in a box 12 whose front wall 13 is provided with pushbuttons with parallel axes X1 and X2, namely a pulse on button 14 and an emergency stop button 15 of the so-called punch type, for controlling, by via transmission elements described below, a control member on 16 and a stop control member 17 of the motor circuit breaker 11. The members 16,17 are buttons pressed by pressure, of the rocking type as described in document EP-559 507, but which can also be of the sliding type ; these organs can take two positions by alternating movements, each remaining maintained in one or the other position, that is to say in the running state of. motor circuit breaker the on-board member 16 is pressed in and the off-member 17 is out, while that in the stop state of the motor circuit breaker the on member 16 is out and the off member 17 pressed.

    Selon l'invention, le bouton marche 14 du coffret est relié à l'organe marche 16 du disjoncteur-moteur par l'intermédiaire d'un organe de transmission 20 déclenchable,de préférence à déclenchement brusque; l'organe de transmission 20 peut prendre une position normale dans laquelle est activée la transmission à l'organe 16 d'une impulsion exercée sur le bouton 14 et une position de sécurité dans laquelle cette transmission est inactivée. D'autre part, entre le bouton d'arrêt d'urgence 15 du coffret et l'organe d'arrêt 17 du disjoncteur-moteur est disposé un mécanisme de sécurité 30 qui agit sur l'organe de transmission 20 pour que celui-ci soit mis dans son état de sécurité lorsque le bouton d'arrêt d'urgence est enfoncé, afin d'inactiver la transmission quand a lieu une tentative de forçage du bouton marche 14.According to the invention, the on button 14 of the box is connected to the member operation 16 of the motor circuit breaker via a transmission member 20 triggerable, preferably abruptly triggered; the transmission member 20 can take a normal position in which transmission to the organ is activated 16 of an impulse exerted on the button 14 and a safety position in which this transmission is disabled. On the other hand, between the emergency stop button 15 of the box and the stop member 17 of the motor circuit breaker is arranged a security 30 which acts on the transmission member 20 so that it is put in its safety state when the emergency stop button is pressed, in order to activate the transmission when an attempt is made to force the start button 14.

    L'organe de transmission à déclenchement brusque 20 comprend ici un levier à genouillère articulée 21 coopérant à une extrémité 22 avec un élément mobile du bouton marche 14 et à l'autre extrémité 23 avec un levier 24 suceptible d'agir par poussée sur l'organe marche 16. Le levier 24 peut tourner autour d'un axe Y1 orthogonal aux axes X1,X2. Le coude 25 du levier à genouillère 21 est appliqué contre une paroi de glissement d'un levier pivotant 31 qui fait partie du mécanisme de sécurité 30. L'organe de transmission à déclenchement brusque 20 peut en variante être constitué par tout autre organe de transmission, apte à prendre un état normal actif et un état de sécurité inactif, entre le bouton marche 14 et l'organe marche 16 du disjoncteur-moteur.The abruptly triggered transmission member 20 here comprises a articulated toggle lever 21 cooperating at one end 22 with a movable element of the start button 14 and at the other end 23 with a lever 24 capable of acting by thrust on the walking member 16. The lever 24 can rotate around an axis Y1 orthogonal to the axes X1, X2. The elbow 25 of the toggle lever 21 is applied against a sliding wall of a pivoting lever 31 which is part of the safety 30. The abruptly triggered transmission member 20 can alternatively be constituted by any other transmission organ, capable of assuming a normal state active and an inactive safety state, between the start button 14 and the start member 16 of the breaker-motor.

    Le levier 31 est en forme approximative de T dont l'âme 32 pivote à son extrémité 32a autour d'un axe X3 parallèle aux axes X1,X2 et dont l'aile 33 porte d'un côté la paroi de glissement 34 pour le coude de la genouillère et de l'autre côté une portée 35 appliquée normalement contre une butée 41 ménagée sur un levier pivotant 40. Un faible ressort de rappel 36,qui est par exemple un ressort en épingle (voir figures 2 à 8) est associé au levier 31 pour tendre à appliquer la paroi 34 contre le coude 25 de la genouillère. Le levier 40 est disposé entre le bouton d'arrêt d'urgence 15 et l'organe d'arrêt 17 du disjoncteur-moteur de façon à pivoter autour d'un axe Y2 parallèle à l'axe Y1 ou confondu avec celui-ci ; il coopère avec la partie mobile 15a du bouton 15 par un appui 42 et avec l'organe 17 par un doigt 43. D'autrte part, un ressort de rappel 44 peut être associé au levier 24 affecté à l'actionnement du bouton marche.The lever 31 has an approximate T shape, the core 32 of which pivots at its end 32a around an axis X3 parallel to the axes X1, X2 and the wing 33 of which carries a side the sliding wall 34 for the knee elbow and on the other side a bearing 35 normally applied against a stop 41 formed on a pivoting lever 40. A weak return spring 36, which is for example a hairpin spring (see Figures 2 to 8) is associated with the lever 31 to tend to apply the wall 34 against the elbow 25 of the kneepad. The lever 40 is disposed between the emergency stop button 15 and the stop member 17 of the motor circuit breaker so as to pivot around an axis Y2 parallel to or coincident with the axis Y1; it cooperates with the mobile part 15a of the button 15 by a support 42 and with the member 17 by a finger 43. On the other hand, a return spring 44 can be associated with lever 24 assigned to actuate the button market.

    Le fonctionnement du dispositif représenté va être décrit en regard des figures 3 à 8.The operation of the device shown will be described with reference to Figures 3 to 8.

    Quand le bouton d'arrêt d'urgence 15 est au repos et que l'opérateur actionne le bouton marche 14 (voir figure 3), l'élément mobile de ce dernier entraíne le levier à genouillère 21 dont le coude 25 glisse sur la paroi 34 du levier 31. Comme le bouton 15 est au repos, le levier 40 est en position haute (voir figure 4) et maintient par sa butée 41 le levier 31; la paroi 34 ne pouvant pas se déplacer, la genouillère ne se déforme pas et contraint le levier 24 à pivoter pour mettre l'organe marche 16 en position active ; simultanément et sous l'effet de la serrure interne du disjoncteur-moteur, l'organe arrêt 17 est amené à sa position sortie, à proximité du doigt 43 du levier 40. En relâchant le bouton 14, l'opérateur laisse celui-ci remonter sous l'effet d'un ressort interne ; le bouton reprend sa position indiquée en tirets sur la figure 3 et les divers éléments des organes 20,30 occupent les positions visibles figure 5.When the emergency stop button 15 is at rest and the operator activates the start button 14 (see Figure 3), the mobile element of the latter drives the toggle lever 21 whose elbow 25 slides on the wall 34 of the lever 31. As the button 15 is at rest, the lever 40 is in the high position (see FIG. 4) and maintains by its stop 41 the lever 31; the wall 34 being unable to move, the toggle does not does not deform and forces the lever 24 to pivot to put the walking member 16 in active position; simultaneously and under the effect of the internal lock of the motor circuit breaker, the stop member 17 is brought to its extended position, near finger 43 of the lever 40. By releasing button 14, the operator lets it go up under the effect an internal spring; the button returns to its position indicated in dashes in Figure 3 and the various elements of the organs 20, 30 occupy the positions visible in FIG. 5.

    Quand l'opérateur actionne le bouton d'arrêt d'urgence 15, celui-ci s'enfonce et, via le levier 42, enfonce l'organe arrêt 17 du disjoncteur-moteur, de sorte que celui-ci est mis à l'arrêt (voir figure 7). De plus, la butée 41 du levier s'abaisse et laisse désormais à la portée 35 du levier 31 la possibilité de se déplacer et donc au levier 31 de pivoter. Simultanément l'organe marche 16 du disjoncteur-moteur est mis en position sortie par la serrure interne du disjoncteur-moteur. Si par inadvertance l'opérateur presse alors le bouton marche 14 (figure 6), la genouillère plie dès que le levier 24 rencontre l'organe 16, car le coude 25 fait pivoter en sens horaire le levier 31 alors libéré (voir figure 8), en tendant le léger ressort 36. Quand l'opérateur relâche sa pression sur le bouton marche 14, les divers éléments des organes 20,30 reviennent à leur position initiale (voir figure 5).When the operator actuates the emergency stop button 15, it sinks and, via lever 42, sinks the stop member 17 of the motor circuit breaker, so that it is stopped (see Figure 7). In addition, the stop 41 of the lever lowers and now leaves the range 35 of the lever 31 the possibility of moving and therefore the lever 31 to pivot. Simultaneously the on-board member 16 of the motor circuit breaker is switched on in the extended position by the internal lock of the motor circuit breaker. If inadvertently the operator then presses the start button 14 (FIG. 6), the knee brace bends as soon as the lever 24 meets the member 16, because the elbow 25 rotates the lever 31 clockwise then released (see figure 8), by stretching the light spring 36. When the operator releases pressing the start button 14, the various elements of the organs 20.30 return to their original position (see Figure 5).
