Description

Relais mecanique auailiaire. 11 arrive frequemment dans 1a pratique clue 1'effort necessaire pour provoquer 1e fonctionnement d'un appareil soit plus Brand que la force dont an dispose, par exemple d'un relais de precision thermique ou m6ca- nique. 0n est alors amene ä prevoir entre 1e relais et 1'appareil principal ä commander, un organe intermediaire capable de fournir 1'effort necessaire pour effectuer cette com- mande. Auxiliary mechanical relay. It frequently happens in practice that the effort required to bring about the operation of a device is greater than the force available to it, for example a thermal or mechanical precision relay. It is then necessary to provide, between the relay and the main apparatus to be controlled, an intermediate member capable of supplying the force necessary to carry out this control.

La presente invention a pour objet un relais mecanique auxiliaire place entre la ser- rure d'un appareil et plusieurs relais de com- mande independants, comportant plusieurs elements montes sur un arbre commun et cooperant chacun avec 1'un des relais de com- mande, 1'arbre portant ces elements etant soli- daire d'un organe en Prise avec un levier de commande relie ä la serrure, de telle maniere que lors d'un declenchement d'un relais, il provoque par une mouvement angulaire, si- multanement et automatiquement, 1e rearme-, ment des relais de commande, la remise en place des elements cooperant avec eux, ainsi que 1'ouverture de la serrure, 1e rearmement manuel de cette derniere provoquant un de- placement angulaire en sens contraire de Far- bre portant lesdits elements, ce qui fait que tous les organes sont alors ä nouveau en Posi tion de fonetionnement. The subject of the present invention is an auxiliary mechanical relay placed between the lock of an appliance and several independent control relays, comprising several elements mounted on a common shaft and each cooperating with one of the control relays. , the shaft carrying these elements being integral with a member in engagement with a control lever connected to the lock, in such a way that when a relay is triggered, it causes by an angular movement, if simultaneously and automatically, the first rearmament, ment of the control relays, the refitting of the elements cooperating with them, as well as the opening of the lock, the first manual rearmament of the latter causing an angular displacement in the opposite direction of Far - bre carrying said elements, which means that all the organs are then again in the operating position.

Le dessin annexe represente, ä titre d'exemple; l'une des multiples formes d'exe- cution possibles de 1'objet de la presente in- vention adaptee ä la commande d'un disjonc- teur par deux relais thermiques ind6pen- dants. The accompanying drawing shows, by way of example; one of the multiple possible embodiments of the object of the present invention adapted to the control of a circuit breaker by two independent thermal relays.

La fig. 1 en est une vue en perspective, les positions respectives des organes corres- pondant ä une Position "enclenchee" de 1'ap- pareil ä commander; La fig. 2 est une vue en perspective du meme relais, les positions respectives des organes correspondant ä une Position "d6clen- ch6e" de 1'appareil ä commander. fig. 1 is a perspective view, the respective positions of the members corresponding to an "engaged" position of the apparatus to be controlled; fig. 2 is a perspective view of the same relay, the respective positions of the members corresponding to a "triggered" position of the device to be controlled.

Selon 1a fig. 1, un cliquet 1 pivote ä Tune de ses extremites sur un axe fixe 2 est commande par un relais contre 1'action d'un ressort 3, qui tend ä maintenir une butee 4 prisonniere dans un evidement 16 de 1'extre- mit6 libre du cliquet 1. Cette butee 4 est solida.ire d'un volant 5 monte fou sur un arbre 6. Ce volant 5 est sollicite par un res- sort 7, qui tend ä faire echapper la butee 4 de 1'evidement 16. Sur ce meme volant 5 est fixe un ergot d'entrainement 8 qui sert en meme temps d'attache pour 1e ressort 7. U ne goupille 9 solidaire de Farbre 6 est destinee 'a venir en Prise avec 1'ergot 8 lors du fonc- tionnement du relais. Sur cet arbre 6 est goupille dans un angle determine un organe constitue par un levier 10 comportant une fente 11 en forme d'arc dans laquelle glisse librement un ergot 12 rive sui 1'extremite libre d'un levier de commande constitue par une manivelle 13, sollicitee par un ressort 1 < l-. L'une des extremites de la fente 11. est Mar- gie de fagon ä former une surface d'appui 1.5 sur laquelle vient reposer Fergot 12 de la manivelle 13 lorsque Fappareil ä. commander est enelenche. According to fig. 1, a pawl 1 pivots at one of its ends on a fixed axis 2 is controlled by a relay against the action of a spring 3, which tends to maintain a stop 4 prisoner in a recess 16 of the free end. of the pawl 1. This stopper 4 is solida.ire a flywheel 5 loosely mounted on a shaft 6. This flywheel 5 is biased by a spring 7, which tends to cause the stopper 4 to escape from the recess 16. On this same flywheel 5 is fixed to a driving lug 8 which serves at the same time as an attachment for the first spring 7. A pin 9 integral with the shaft 6 is intended to come into engagement with the lug 8 during operation. of the relay. On this shaft 6 is pinned in a determined angle a member constituted by a lever 10 comprising a slot 11 in the form of an arc in which a lug 12 slides freely along the free end of a control lever constituted by a crank 13 , solicited by a spring 1 < l-. One of the ends of the slot 11. is Margie so as to form a bearing surface 1.5 on which Fergot 12 of the crank 13 comes to rest when the apparatus is in operation. order is enelenche.

Un deuxieme ensemble cliquet volant semblable ä celui qui vient d.'etr,e decrit e:st prevu sur Farbre 6 pour 1a, commande du dis- joncteur par un deuxieme relais entierement independant. A second flywheel pawl assembly similar to that just described is provided on the shaft 6 for the control of the circuit breaker by a second fully independent relay.

Le fonetionnement du dispositif est 1e suivant: Admettons quo los conditions soient tolles quo 1'un des relais doive declencher et agir sur 1'appa.reil ä comma.nder qui peut "eire un disjoncteur par exemple. The operation of the device is as follows: Let us assume that the conditions are tolles that one of the relays must trigger and act on the device to be controlled which can be a circuit breaker for example.

Dans ce cas, 1e relais exerce une poussee sur 1e cliquet 1 en sens contraire de Faction du ressort 3 jusqu'ä degagement de la butee 4 de 1'evidement 1.6 du cliquet 1.. L'effort necessaire pour effectuer ce degagement est tres faible et peut etre fourni par un relais de precision. Des quo la butee 4 solidaire du volant 5 est liberee, celui-ei execute un mouvement de rotation accelere sur Farbre 6 sous Faction du ressort 7. Lorsque gräce ä. ce mouvement accelere la masse du volant 5 a acquis une force vive suffisante, son ergot 8 vient en Prise avee la goupille 9 solidaire de Faxe 6 et Fentraine. Le levier 10 goupille sur laxe 6 est entraine en meme temps quo celui-ei et sa, face d'appui 1.5 glisse sous Fergot 12 jusqu'ä, ce que celui-ei se trouve en face de la fente 11. A ce moment, la manivelle 13 sollicitee par un ressort 14 pivote autour de son axe 17 et commande 1e declenehement du disjoncteur, dune Part, et 1e rearmement des relais de commande, d'autre Part. Ce RTI ID="0002.0278" WI="19" HE="4" LX="1459" LY="484"> rea.rmement est conimande par Fergot 12 qui coulisse dans la fente 11 de forme tolle qu'en fin de course de la mani- velle 13, la butee 4 solidaire du volant 5, entmine par son ergot 8 et la goupille 9 de Farbre 6, se trouve dans une Position en deQa de la Position quelle occupait avant 1e fone- tionnement du relais (fig. 2). In this case, the relay exerts a thrust on the pawl 1 in the opposite direction to the action of the spring 3 until the abutment 4 disengages from the recess 1.6 of the pawl 1. The effort required to effect this disengagement is very low. and can be supplied by a precision relay. As soon as the stopper 4 integral with the flywheel 5 is released, the latter executes an accelerated rotational movement on the shaft 6 under the action of the spring 7. When thanks to. this movement accelerates the mass of the steering wheel 5 has acquired sufficient momentum, its lug 8 comes into engagement with the pin 9 integral with Faxe 6 and Fentraine. The lever 10 pinned on the axis 6 is driven at the same time as the latter and its bearing face 1.5 slides under Fergot 12 until the latter is opposite the slot 11. At this moment, the crank 13 urged by a spring 14 pivots around its axis 17 and controls the first triggering of the circuit breaker, on the one hand, and the first resetting of the control relays, on the other hand. This RTI ID="0002.0278" WI="19" HE="4" LX="1459" LY="484"> rea.rment is commanded by Fergot 12 which slides in the slot 11 in a tolle form until the end of stroke of the crank 13, the stopper 4 secured to the flywheel 5, leading by its lug 8 and the pin 9 of the shaft 6, is in a position below the position which it occupied before the first operation of the relay (fig. 2).

Une campe 1.8 prevue sur 1'extremite du cliquet l einpeehe un coincement eventuel de la butee 4 sur 1'extremite de ce cliquet. A camp 1.8 provided on the end of the pawl einpeehe a possible jamming of the stop 4 on the end of this pawl.

Lors du mouvement d'armement de 1a. serrure du disjoncteur, la manivelle 13 est ramenee par celui-ei dans sa Position primi tive contre Faction du ressort 14. Au cours de ce mouvement. Fergot 12 glisse dann la fente 11. du levier 10 ce qui fait pivoter Far bre 6 dans un sens tel quo la butee 4 vienne ü nouveau s'appuyer sur la faoe de 1'evide- ment 16. Puis Farbre 6 continuant ä tour- ner, la goupille 9 quitte Fergot 8 jusqtt'ä, ce quo Fergot 12 se trouve au-dessus de la.face d'appui 15: ä ce moment, la forme de 1'ex- tremite de la rainure de guidage 11 et le poids du levier 10 ramme celui-ei en arriere et la. face 15 vient se placer sous 1'ergot 12. Puis, lors dun iouvement d'enclenehement du disjoneteur, la iuanivelle 13 est liberee de 1'organe qui Factionne et vient, sous Faction du ressort 14, s'appuyer sur la face 15. L'ap- pareil est a.insi prei pour un nouveau fonc- tionnement. During the arming movement of 1a. circuit breaker lock, the crank 13 is brought back by the latter in its primitive position against the action of the spring 14. During this movement. Fergot 12 slides in the slot 11. of the lever 10 which causes Far bre 6 to pivot in a direction such that the stopper 4 comes to rest again on the face of the recess 16. Then shaft 6 continues to rotate, pin 9 leaves Fergot 8 until Fergot 12 is above bearing face 15: at this moment, the shape from the end of the guide groove 11 and the weight of the lever 10 rammes it back and forth. face 15 comes to be placed under 1'ergot 12. Then, during a triggering movement of the circuit breaker, the level 13 is released from the organ which activates and comes, under the action of the spring 14, to rest on the face 15. The appliance is thus prepared for a new operation.

Il est clair qn'il est possible de disposer de fagon differente los < livers organes du relais auxiliaire decrit ici z titre d'exemple il est en particulier possible de prevoir un ou plusieurs relais agissant sur 1e meme arbre 6, il suffit pour cela de prevoir Farbre 6 de longueur suffisante pour y monter 1e nom- bre de relais necessaires. Les volants etant montes fous sur Farbre 6, chaque relais agit individuellement, tandis qu'ils sont tous rear- mes simultanement par 1'intermediaire de leurs ergots 8 et goupilles 9. It is clear that it is possible to have the bodies of the auxiliary relay described here in a different way. As an example, it is in particular possible to provide one or more relays acting on the same shaft 6. provide shaft 6 with sufficient length to fit the number of relays required. Since the flywheels are loosely mounted on the shaft 6, each relay acts individually, while they are all reset simultaneously by means of their lugs 8 and pins 9.

Le relais auxiliaire utilise pour la com- mande d'un disjoncteur par un relais thermi- que decrit ici ä titre d'exemple peut etre adapte ä d'autres genres de relais ainsi qu'h d'autres appareils ä commander, saus sortir du cadre de la presente invention. The auxiliary relay used for the control of a circuit breaker by a thermal relay described here by way of example can be adapted to other types of relays as well as to other devices to be controlled, without leaving the framework of the present invention.
