Abstract

The switch has a padlocking accessory with a sheath (30) fixed with respect to a fixed extended trunk. A crown (40) has openings (45), at its upper edge (44), for passage of a padlock. The crown is mounted outside the sheath for moving between an inactive lower position and an active upper position, to disengage a movable actuating head (10) to a lower position and to surmount the head by the upper edge into upper position.

Description

La présente invention concerne un bouton-poussoir à accrochage, notamment un bouton d'arrêt d'urgence, destiné à commander un organe interrupteur et comprenant une tête d'actionnement mobile et un fût allongé fixe.The present invention relates to a latching pushbutton, in particular an emergency stop button, for controlling a switch member and comprising a movable actuating head and a fixed elongated barrel.

De tels boutons-poussoirs sont destinés à être montés sur un support plan, la tête étant apte à coulisser selon un axe principal perpendiculaire au support pour prendre une position sortie et une position enfoncée. Le fût est agencé pour traverser une ouverture du support et être fixé au dessous du support. Par "accrochage", on veut dire qu'une pression exercée sur le bouton entraîne son abaissement vers une position enfoncée qui reste maintenue, la position initiale ne pouvant être rétablie que par une nouvelle action exercée manuellement, directement ou par une clé, sur le bouton.Such push buttons are intended to be mounted on a flat support, the head being able to slide along a main axis perpendicular to the support to take an extended position and a depressed position. The drum is arranged to pass through an opening of the support and be fixed below the support. By "hooking", it is meant that a pressure exerted on the button causes it to be lowered to a depressed position which remains maintained, the initial position can only be restored by a new action exerted manually, directly or by a key, on the button.

Dans les boutons d'arrêt d'urgence (voir par exemple le document FR 2 521 768 ), l'organe interrupteur est commandé par un mécanisme à rupture brusque qui se déclenche quand l'utilisateur exerce une pression sur la tête, afin de mettre en oeuvre un circuit électrique de sécurité. Le bouton peut ensuite être rétabli dans son état normal par un réarmement du mécanisme sous l'effet d'une rotation ou d'une traction exercée sur la tête.In the emergency stop buttons (see for example the document FR 2,521,768 ), the switch member is controlled by a snap mechanism that triggers when the user exerts pressure on the head, to implement an electrical safety circuit. The button can then be restored to its normal state by resetting the mechanism under the effect of a rotation or traction exerted on the head.

Le document US 2850587 décrit un dispositif selon les préambules des revendications 1 et 7.The document US 2850587 describes a device according to the preambles of claims 1 and 7.

Il est souhaitable de pouvoir cadenasser un bouton-poussoir à accrochage, et spécialement un bouton d'arrêt d'urgence, afin d'éviter qu'un opérateur ne ramène de manière intempestive la tête dans sa position initiale sortie. Il existe des dispositifs de verrouillage connus à capot cadenassable basculant, mais ces dispositifs sont relativement complexes et peu commodes.It is desirable to be able to lock a latching pushbutton, and especially an emergency stop button, to prevent an operator from inadvertently returning the head to its initial position out. There are known locking devices with tilting padlock, but these devices are relatively complex and inconvenient.

On sait aussi utiliser pour cadenasser un bouton d'arrêt d'urgence un accessoire en forme de tulipe monté fixe autour du bouton (catalogue Schneider Electric, Automatismes Industriels 2001, page C100). Un tel accessoire présente à son bord supérieur des orifices qui, quand la tête a été activée et enfoncée, sont alors dégagés et autorisent l'introduction de cadenas. L'inconvénient de cet accessoire est qu'il gêne la commande manuelle de la tête du bouton.It is also known to use to lock an emergency stop button a tulip shaped accessory mounted around the button (Schneider Electric catalog, Industrial Automation 2001, page C100). Such an accessory has at its upper edge openings which, when the head has been activated and depressed, are then released and allow the introduction of padlocks. The disadvantage of this accessory is that it hinders the manual control of the button head.

L'invention a pour but de permettre de cadenasser un bouton-poussoir à accrochage, particulièrement un bouton d'arrêt d'urgence, au moyen d'un accessoire simple, bien adapté à la structure du bouton et ne perturbant pas l'actionnement de la tête du bouton par l'opérateur.The object of the invention is to enable a latching push-button, particularly an emergency stop button, to be padlocked by means of a simple accessory that is well adapted to the structure of the button and does not disturb the actuation of the button. the head of the button by the operator.

Selon l'invention, l'accessoire de cadenassage comprend

  • un fourreau fixe par rapport au fût et de forme intérieure adaptée à la partie haute du fût,
  • une couronne présentant à son bord supérieur au moins un orifice de passage de cadenas, la couronne étant montée sur l'extérieur du fourreau pour se déplacer entre une position basse inactive et une position haute active, par un mouvement limité au moyen d'éléments de butée, de manière à dégager la tête en position basse et à surmonter la tête par son bord supérieur en position haute.
According to the invention, the lockout accessory comprises
  • a sheath fixed relative to the barrel and of inner shape adapted to the upper part of the barrel,
  • a crown having at its upper edge at least one padlock passage, the ring being mounted on the outside of the sleeve to move between an inactive low position and a high active position, by a limited movement by means of elements of stop, so as to release the head in the low position and to overcome the head by its upper edge in the high position.

La couronne, qui de préférence coulisse par rapport au fourreau et est empêchée de tourner par des éléments d'indexation, peut présenter une butée qui, en position haute, coopère avec une collerette externe située en haut du fourreau. La pose de l'accessoire peut être facilitée si le fourreau présente en bas un appui interne sur lequel repose un rebord annulaire du fût du bouton-poussoir. Il est avantageux que le bord supérieur de la couronne offre deux échancrures ouvertes vers le haut et facilitant la préhension de la tête d'actionnement quand la couronne est en position basse de repos.The ring, which preferably slides relative to the sleeve and is prevented from rotating by indexing elements, may have a stop which, in the upper position, cooperates with an outer collar located at the top of the sheath. The installation of the accessory can be facilitated if the sheath has at the bottom an internal support on which rests an annular rim of the barrel of the push-button. It is advantageous that the upper edge of the crown provides two notches open upwards and facilitates the gripping of the actuating head when the crown is in the low rest position.

De préférence, l'accessoire de cadenassage est un sous-ensemble unitaire formé par un assemblage télescopique de la couronne avec le fourreau, afin de pouvoir être rapporté d'une pièce au bouton-poussoir.Preferably, the padlocking accessory is a unitary subassembly formed by a telescopic assembly of the crown with the sheath, so that it can be attached in one piece to the pushbutton.

L'invention concerne aussi l'accessoire de cadenassage proprement dit, doté d'un fourreau et d'une couronne montée sur l'extérieur du fourreau, la couronne présentant à son bord supérieur au moins un orifice de passage de cadenas, et étant apte à se déplacer entre une position basse inactive et une position haute active, par un mouvement de coulissement limité au moyen d'éléments de butée, en restant assemblée au fourreau.

Le bouton d'arrêt d'urgence A illustré sur les figures est destiné à être monté sur un su p-port plan B (voir figures 6 à 8), tel qu'un panneau, pupitre, coffret, etc.., et il est doté d'un accessoire de cadenassage C susceptible de recevoir un ou plusieurs cadenas D. Le bouton A est de révolution autour d'un axe X et possède une tête de poussée coulissante 10 et un fût cylindrique fixe 20. La tête de poussée 10 a une partie épanouie 11 propre à être actionnée par l'opérateur et une jupe cylindrique 12 guidée sur le fût. Le fût 20, qui en variante pourrait être prismatique, a une partie haute 21 de guidage de la tête, et une partie basse 22 de fixation contre l'envers du support par un élément 23 de tout type connu (utilisant par exemple un écrou, ou une embase de fixation à vis de serrage). Un joint 24 est prévu pour assurer l'étanchéité du passage du fût dans une ouverture circulaire 25 du support B, le joint étant posé sur un rebord 26. Le fût inclut un mécanisme d'actionnement d'un circuit électrique qui n'est pas l'objet de l'invention.The emergency stop button A illustrated in the figures is intended to be mounted on a plane port B (see Figures 6 to 8 ), such as a panel, desk, cabinet, etc., and it is equipped with a padlocking accessory C may receive one or more padlocks D. The button A is of revolution about an axis X and has a sliding thrusting head 10 and a fixed cylindrical barrel 20. The thrusting head 10 has a blooming portion 11 adapted to be actuated by the operator and a cylindrical skirt 12 guided on the barrel. The barrel 20, which could alternatively be prismatic, has an upper part 21 for guiding the head, and a lower part 22 for fixing against the back of the support by an element 23 of any known type (using, for example, a nut, or a clamping screw mounting base). A seal 24 is provided to seal the passage of the barrel in a circular opening 25 of the support B, the seal being placed on a flange 26. The barrel includes a mechanism for actuating an electrical circuit that is not the subject of the invention.

De façon préférentielle, l'accessoire de cadenassage C est constitué par un sous-ensemble unitaire télescopique, obtenu par l'assemblage indémontable d'un fourreau 30 et d'une couronne 40 mobile relativement au fourreau, le sous-ensemble étant adjoint au bouton-poussoir de manière à l'envelopper sans gêne.Preferably, the padlocking accessory C is constituted by a telescopic unitary subassembly, obtained by the unmountable assembly of a sleeve 30 and a ring 40 movable relative to the sleeve, the subassembly being attached to the button -poussoir so as to wrap it without embarrassment.

Le fourreau 30 est posé de façon à envelopper le fût 20 tout en laissant dégagée la partie d'actionnement 11 de la tête, tant en position sortie qu'en position enfoncée. Il présente une face interne cylindrique 31 adaptée à la forme extérieure du fût et une face externe 32 à parties cylindriques. A son extrémité haute, le fourreau offre une collerette externe 33 servant de butée haute à la couronne ; à son extrémité basse, le fourreau offre un appui interne 34 pour recevoir le fût et une portée externe 35 limitant le mouvement de la couronne vers le bas (voir figure 8). Les termes "interne" et "externe" désignent le côté des pièces situé radialement vers l'intérieur et respectivement vers l'extérieur.The sleeve 30 is placed so as to surround the barrel 20 while leaving the actuating portion 11 of the head free, both in the extended position and in the depressed position. It has a cylindrical inner face 31 adapted to the outer shape of the barrel and an outer face 32 with cylindrical portions. At its upper end, the sheath offers an outer collar 33 serving as a high stop to the crown; at its lower end, the sheath provides an internal support 34 to receive the barrel and an outer bearing 35 limiting the movement of the crown down (see figure 8 ). The terms "inner" and "outer" refer to the side of the pieces located radially inwards and outwards, respectively.

Entre la face interne 31 du fourreau et la face en regard du fût est ménagé un espace pour loger la jupe 12 de la tête 10. Il est prévu un élément d'encliquetage 36, point dur ou élément analogue de retenue, pour maintenir la couronne en position basse sur le fourreau et un élément d'indexation 37 pour guider le mouvement de la couronne (voir figure 6). Un élément d'encliquetage 38, point dur ou élément analogue de retenue est aussi prévu pour maintenir la couronne en position haute sur le fourreau (voir figure 7 ; l'élément 38 est montré au moyen d'une coupe dans un plan diamétral différent de celui de la figure 6).Between the inner face 31 of the sheath and the face facing the barrel is provided a space for housing the skirt 12 of the head 10. There is provided a detent element 36, hard point or similar retaining element, to hold the crown in the lower position on the sheath and an indexing element 37 to guide the movement of the crown (see figure 6 ). A latching element 38, hard point or similar retaining element is also provided to hold the crown in the upper position on the sheath (see FIG. figure 7 ; the element 38 is shown by means of a section in a diametrical plane different from that of the figure 6 ).

La couronne 40 est mobile en translation selon la direction X par rapport au fourreau 30, de façon limitée en haut par la collerette 33 et en bas par la portée 35. La couronne a une face interne 41 et une face externe 42, toutes deux cylindriques. Une large ouverture latérale 43 est prévue pour faciliter la juxtaposition de boutons dans un encombrement min i-mal. La couronne a un bord supérieur 44 qui présente d'une part trois orifices 45 de passage pour différents cadenas, ces orifices étant distribués à 120°, et d'autre part deux échancrures 46 ouvertes vers le haut et diamétralement opposées, destinées à faciliter la préhension de la tête lors d'une traction de réarmement. La couronne 40 offre à sa partie basse une butée interne 47 prévue pour coopérer avec la collerette 33 du fourreau 30, et vers l'intérieur un bord biseauté ou arrondi 48. Il est prévu à l'intérieur de la couronne une rainure 49 dirigée selon l'axe X pour guider l'élément d'indexation 37 (bille, picot ou élément analogue) prévu à l'extérieur du fourreau.The ring gear 40 is movable in translation in the X direction relative to the sleeve 30, limited at the top by the collar 33 and at the bottom by the bearing surface 35. The ring has an inner face 41 and an outer face 42, both cylindrical . A wide lateral opening 43 is provided to facilitate the juxtaposition of buttons in a mini- mal space. The ring has an upper edge 44 which has on the one hand three orifices 45 of passage for different padlocks, these orifices being distributed at 120 °, and on the other hand two notches 46 open upwards and diametrically opposite, intended to facilitate the gripping the head during a rearming pull. The ring 40 has at its lower part an internal abutment 47 designed to cooperate with the flange 33 of the sleeve 30, and inwardly a beveled or rounded edge 48. There is provided inside the ring a groove 49 directed according to the X axis for guiding the indexing element 37 (ball, pin or similar element) provided outside the sheath.

Le fonctionnement de l'accessoire de cadenassage va être expliqué en regard des fig ures. Les figures 1,4 et 6 montrent le bouton d'arrêt d'urgence A en position de repos. Le fourreau 30 enveloppe le fût en reposant sur la face supérieure du support B. Des dégagements rectilignes peuvent être prévus sous le fourreau pour l'aligner sur une nervure éventuelle du support. La couronne de cadenassage 40 est maintenue en position basse sur le fourreau par application de son bord 48 contre la portée externe 35 du fourreau. Lors d'un arrêt d'urgence, l'opérateur presse la tête 10 qui vient dans la position indiquée en tirets sur la figure 1. Il convient d'observer que l'accessoire de cadenassage, par sa forme et sa disposition, ne gêne pas la manoeuvre du bouton par l'opérateur.The operation of the padlocking accessory will be explained with reference to FIGS. The figures 1 , 4 and 6 show the emergency stop button A in the rest position. The sheath 30 wraps the barrel resting on the upper face of the support B. Straight clearances may be provided under the sheath to align with a possible rib of the support. The lockout ring 40 is held in the lower position on the sheath by applying its edge 48 against the outer bearing surface 35 of the sheath. During an emergency stop, the operator presses the head 10 which comes in the position indicated in dashes on the figure 1 . It should be noted that the lockout accessory, by its shape and its arrangement, does not hinder the operation of the button by the operator.

Si l'opérateur ne souhaite pas cadenasser le bouton, il peut saisir facilement la partie 11 de la tête qui est alors enfoncée et exercer sur elle un mouvement de traction ou rotation pour réarmer le bouton avec retour de la tête à sa position normale inactive. Les échancrures 46 lui permettent éventuellement d'exercer une meilleure prise sur le bord de la partie 11.If the operator does not wish to lock the button, he can easily grasp the part 11 of the head which is then depressed and exert on it a traction or rotation movement to reset the button with return of the head to its normal inactive position. The notches 46 allow it to possibly exercise a better grip on the edge of the portion 11.

Si l'opérateur veut cadenasser le bouton, il fait monter la couronne qui franchit le point dur 36 et coulisse sur le fourreau, avec glissement de l'élément d'indexation 37 du fourreau dans la rainure de guidage 48. Quand la butée 47 s'applique contre la collerette 33 (figures 2,5 et 7), la couronne est parvenue à sa position active haute. Les orifices 45 sont alors suffisamment dégagés de la partie épanouie 11 de la tête pour que l'on puisse engager un à trois cadenas D, comme indiqué figure 7. Pour décadenasser le bouton, l'opérateur retire le cadenas D et fait descendre la couronne qui glisse sur le fourreau jusqu'à buter contre sa portée 35 et/ou contre le support B. Il peut alors ramener le bouton à sa position de repos.If the operator wants to lock the button, it raises the crown that crosses the hard point 36 and slides on the sleeve, with sliding of the indexing element 37 of the sleeve in the guide groove 48. When the stop 47 s against the flange 33 ( figures 2 , 5 and 7 ), the crown has reached its active high position. The orifices 45 are then sufficiently clear of the open part 11 of the head so that one can engage one to three padlocks D, as indicated figure 7 . To unlock the button, the operator removes the padlock D and down the crown that slides on the sleeve to abut against its scope 35 and / or against the support B. It can then return the button to its rest position.
