Selon ces dispositifs ou mécanismes connus jusqu'à présent forment interrupteur, le verrouillage des contacts se fait par l'intermédiaire d'un système bielle-manivelle comportant un grand nombre de pièces et dont le montage est difficile tout en étant bien entendu d'un coût relativement élevé à cause du nombre des pièces et de l'emploi d'une main-d'oeuvre importante.According to these devices or mechanisms known up to now form a switch, the locking of the contacts is done by means of a connecting rod-crank system comprising a large number of parts and the assembly of which is difficult while being of course relatively high cost because of the number of parts and the use of large labor.

La présente invention a donc pour but de remédier aux inconvénients précités en fournissant une solution selon laquelle le nombre de pièces est réduit et le montage aisé. De préférence, cette solution doit en outre présenter l'avantage d'occuper un volume plus faible que les dispositifs antérieurs.The present invention therefore aims to remedy the aforementioned drawbacks by providing a solution according to which the number of parts is reduced and the assembly is easy. Preferably, this solution must also have the advantage of occupying a smaller volume than the prior devices.

En outre, la solution selon la présente invention doit être de préférence d'une grande adaptabilité en pouvant être applicable non seulement au verrouillage des contacts d'interrupteurs mais également à d'autres applications générales nécessitant le déplacement d'un élément mécanique tel qu'un bras.In addition, the solution according to the present invention must preferably be of great adaptability, being able to be applicable not only to the locking of the switch contacts but also to other general applications requiring the displacement of a mechanical element such as an arm.

Cette solution consiste selon la présente invention en un dispositif, montable dans un bâti, de commande du déplacement d'un bras entre au moins deux positions, une première position dite d'arrêt et une deuxième position dite de service, comprenant un organe, déplaçable en translation et/ou en rotation dans le plan de déplacement du bras entre au moins deux positions, une première position dite «hors fonctionnement», correspondant à ladite position d'arrêt du bras et une deuxième position dite «en fonctionnement» correspondant à ladite position de service du bras, de commande dudit bras par l'intermédiaire d'un élément de transmission prenant appui sur ledit bras de manière librement coulissante pour permettre le déplacement dudit élément de transmission le long dudit bras dans son plan de déplacement et entre trois positions distinctes avantageusement non alignées, une première position dite enclenchée pour laquelle ledit bras est dans ladite position de service, une deuxième position dite déclenchée et une troisième position dite de réenclenchement ou d'armement pour lesquelles deuxième et troisième positions ledit bras est dans ladite position d'arrêt: et un dispositif de verrouillage comprenant un élément allongé monobloc prenant appui, dans la position verrouillée, à une extrémité contre une butée d'arrêt tandis que l'autre extrémité coopère avec ledit élément de transmission, ledit dispositif de verrouillage étant déplaçable entre au moins deux positions, une première position dite «verrouillée», une deuxième position dite «déverrouillée» et reprenant par ailleurs sa position verrouillée lorsque l'élément de transmission est déplacé vers sa troisième position de réenclenchement, caractérisé en ce que l'extrémité de l'élément allongé monobloc opposée à l'extrémité prenant appui contre ladite butée d'arrêt est solidaire dudit élément de transmission.According to the present invention, this solution consists of a device, mountable in a frame, for controlling the movement of an arm between at least two positions, a first so-called stop position and a second so-called service position, comprising a movable member. in translation and / or in rotation in the plane of movement of the arm between at least two positions, a first position called "non-operating", corresponding to said arm stop position and a second position called "in operation" corresponding to said operating position of the arm, controlling said arm by means of a transmission element bearing on said arm in a freely sliding manner to allow movement of said transmission element along said arm in its plane of movement and between three positions advantageously separate, not aligned, a first so-called engaged position for which said arm is in said service position, a second position said triggered and a third position called resetting or arming for which second and third positions said arm is in said stopped position: and a locking device comprising a one-piece elongated element bearing, in the locked position, at one end against a stopper while the other end cooperates with said transmission element, said locking device being movable between at least two positions, a first position called "locked", a second position called "unlocked" and also taking up its locked position when the transmission element is moved to its third reset position, characterized in that the end of the elongated one-piece element opposite the end bearing against said stopper is integral with said transmission element .

Selon un mode de réalisation particulier, l'élément de transmission précité est constitué par l'une des deux extrémités d'une biellette dite de transmission dont l'autre extrémité coopère avec l'organe de commande. Avantageusement, l'extrémité de la biellette constituant l'élément de transmission prend appui par contact roulant ou glissant sur le bras précité tandis que l'autre extrémité coopérant avec l'organe de commande est articulée sur celui-ci.According to a particular embodiment, the aforementioned transmission element consists of one of the two ends of a so-called transmission link, the other end of which cooperates with the control member. Advantageously, the end of the link constituting the transmission element bears by rolling or sliding contact on the aforementioned arm while the other end cooperating with the control member is articulated on the latter.

Selon encore un autre mode de réalisation particulier, l'extrémité de l'élément allongé précité solidaire de l'élément de transmission est articulée sur ledit élément de transmission. La butée d'arrêt est fixe et est formée par un épaulement contre lequel vient buter l'extrémité correspondante de l'élément allongé.According to yet another particular embodiment, the end of the above-mentioned elongate element secured to the transmission element is articulated on said transmission element. The stopper is fixed and is formed by a shoulder against which the corresponding end of the elongated element abuts.

Selon une variante, la butée d'arrêt précitée peut être mobile et dans ce cas le moyen de déclenchement automatique précité est avantageusement prévu pour agir sur la butée d'arrêt afin de déplacer ladite butée d'arrêt pour déverrouiller le dispositif de verrouillage.According to a variant, the abovementioned abutment can be movable and in this case the abovementioned automatic triggering means is advantageously provided to act on the abutment in order to move said abutment to unlock the locking device.

Selon encore un autre mode de réalisation particulier, l'élément de transmission précité et le dispositif de verrouillage peuvent être réalisés en une seule pièce monobloc et, de préférence, l'élément de transmission, le dispositif de verrouillage et l'organe de commande peuvent également être réalisés en une seule pièce monobloc en simplifiant ainsi avantageusement considérablement la structure du dispositif.According to yet another particular embodiment, the aforementioned transmission element and the locking device can be made in a single piece and, preferably, the transmission element, the locking device and the control member can also be produced in a single piece, thereby advantageously simplifying the structure of the device considerably.

Ce dispositif de commande est applicable comme interrupteur et de ce fait la présente invention concerne également une application du dispositif de commande précité comme interrupteur et dans ce cas le bras précité est électriquement conducteur et comprend à son extrémité libre un plot de contact coopérant dans la deuxième position de service précitée avec un élément de contact fixe comportant un plot de contact correspondant et électriquement conducteur.This control device is applicable as a switch and therefore the present invention also relates to an application of the aforementioned control device as a switch and in this case the aforementioned arm is electrically conductive and comprises at its free end a contact pad cooperating in the second aforementioned service position with a fixed contact element comprising a corresponding and electrically conductive contact pad.

Avantageusement, on peut disposer plusieurs dispositifs précités en parallèle sur un même circuit ou sur des circuits différents. Si plusieurs dispositifs sont disposés en parallèle, il est alors avantageusement prévu un moyen d'accouplement des organes de commande précités entre eux. Selon un mode de réalisation avantageux, un arbre pivotant unique est disposé près de l'extrémité de l'élément allongé de chaque dispositif précité opposée à celle solidaire de l'élément de transmission et comprend des prolongements associés auxdites extrémités et en nombre égal au nombre d'éléments allongés, susceptibles par un déplacement relatif des éléments allongés avec les butées d'arrêt avec lesquelles ils coopèrent, de rompre l'appui des éléments allongés contre les butées d'arrêt, ledit arbre pivotant étant pourvu d'une lamelle rigide dans l'axe de débattement ou de déclenchement de chaque élément allongé de manière que lorsqu'un élément allongé est déclenché, ledit élément allongé déclenché agit sur sa lamelle associée et entraîne le pivotement dudit arbre pivotant et des prolongements qui lui sont solidaires et qui provoquent à leur tour le déclenchement des autres dispositifs de verrouillage de manière à couper complètement le(s) circuit(s).Advantageously, one can have several aforementioned devices in parallel on the same circuit or on different circuits. If several devices are arranged in parallel, there is then advantageously provided a means of coupling the aforementioned control members together. According to an advantageous embodiment, a single pivoting shaft is arranged near the end of the elongated element of each aforementioned device opposite to that secured to the transmission element and comprises extensions associated with said ends and in number equal to the number elongated elements, susceptible by relative displacement of the elongated elements with the stops with which they cooperate, to break the support of the elongated elements against the stops, said pivoting shaft being provided with a rigid lamella in the axis of movement or triggering of each elongated element so that when an elongated element is triggered, said elongated element triggered acts on its associated lamella and causes the pivoting of said pivoting shaft and of the extensions which are integral with it and which cause in turn the triggering of other locking devices so as to completely cut the circuit (s).

Ainsi, on peut constater que le dispositif selon la présente invention a un nombre réduit de pièces et que leur montage est aisé. En outre, il a l'avantage d'occuper un volume beaucoup plus faible que celui des dispositifs antérieurs. Egale- ment, l'adjonction d'un moyen de rappel, notamment élastique, tel qu'un ressort coopérant avec l'organe de commande, permet lorsque le dispositif de verrouillage est en position déverrouillée et que l'extrémité de la biellette constituant l'élément de transmission est rendue libre et ne transmet plus l'effort important de pression sur le bras de l'organe de commande, de permettre à l'élément de transmission de revenir à sa première position enclenchée en passant obligatoirement par la troisième position de réenclenchement pour laquelle le dispositif de verrouillage reprend sa position verrouillée ce qui rend possible ensuite l'amenée du bras dans la deuxième position de service permettant de réaliser la fermeture des contacts dans le cas de l'application comme interrupteur.Thus, it can be seen that the device according to the present invention has a reduced number of parts and that their assembly is easy. In addition, it has the advantage of occupying a much smaller volume than that of the prior devices. Also, the addition of a return means, in particular elastic, such as a spring cooperating with the control member, allows when the locking device is in the unlocked position and the end of the link constituting the the transmission element is made free and no longer transmits the significant pressure force on the arm of the control member, to allow the transmission element to return to its first engaged position, necessarily passing through the third position resetting for which the locking device returns to its locked position, which then makes it possible to bring the arm into the second service position, making it possible to close the contacts in the case of application as a switch.

D'autre part, lors du déclenchement automatique du dispositif de verrouillage et de la libération du bras, la masse mobile de l'ensemble des pièces mise en mouvement est faible, ce qui permet dans l'application du dispositif selon la présente invention comme interrupteur une ouverture rapide du plot de contact mobile solidaire du bras en coupant ainsi le courant. Cette ouverture rapide des contacts est favorable à la coupure des courants importants.On the other hand, during the automatic release of the locking device and the release of the arm, the mobile mass of all the parts set in motion is low, which allows in the application of the device according to the present invention as a switch rapid opening of the movable contact pad secured to the arm, thereby cutting off the current. This rapid opening of the contacts is favorable for breaking the large currents.

Par ailleurs, le bras précité est avantageusement incliné par rapport à l'élément de transmission, où l'extrémité de la biellette pouvant le constituer, selon un angle d'inclinaison prédéterminé de sorte que la partie du bras coopérant avec l'élément de transmission et lui servant de chemin de roulement ou de glissement ait pour effet de faire rouler ou glisser l'élément de transmission sur le bras en cas de déclenchement du dispositif de verrouillage. En outre, lorsque le mécanisme de commande est dans la position de service tel que décrit ci-dessus, l'effort très important s'exerçant sur le bras se subdivise en deux composantes dont l'une s'exerce sur l'élément de transmission et l'autre correspond à la pression contrebalancée par le dispositif de verrouillage. De ce fait, en choisissant un angle d'inclinaison approprié, l'effort exercé sur le dispositif de verrouillage est suffisamment faible pour permettre, dans l'application du disppositif selon la présente invention comme interrupteur le déverrouillage du mécanisme grâce à un effort très faible à l'aide du moyen de déclenchement automatique qui peut être par exemple constitué par un déclencheur électromagnétique, ou une bilame métallique.Furthermore, the aforementioned arm is advantageously inclined relative to the transmission element, where the end of the link can constitute it, at a predetermined angle of inclination so that the part of the arm cooperating with the transmission element and serving as a raceway or sliding has the effect of rolling or sliding the transmission element on the arm in the event of release of the locking device. In addition, when the control mechanism is in the service position as described above, the very large force exerted on the arm is subdivided into two components, one of which is exerted on the transmission element. and the other corresponds to the pressure counterbalanced by the locking device. Therefore, by choosing an appropriate angle of inclination, the force exerted on the locking device is low enough to allow, in the application of the device according to the present invention as a switch, the unlocking of the mechanism thanks to a very low force. using the automatic triggering means which can for example be constituted by an electromagnetic trigger, or a metallic bimetallic strip.

Par ailleurs, comme mentionné précédemment, le dispositif selon la présente invention permet un déplacement du bras précité entre chacune des première position d'arrêt et deuxième position de service précitées alors que le dispositif de verrouillage reste verrouillé. Cette disposition est avantageuse étant donné qu'elle évite toute usure prématurée du mécanisme de verrouillage.Furthermore, as mentioned above, the device according to the present invention allows a movement of the aforementioned arm between each of the aforementioned first stop position and second service position while the locking device remains locked. This arrangement is advantageous since it avoids any premature wear of the locking mechanism.

En outre, comme mentionné précédemment lorsque le dispositif de la présente invention est appliqué comme interrupteur multipolaire à pôles parallèles, il permet de provoquer par un système simple le déverrouillage du dispositif de verrouillage de tous les pôles parallèles lorsque l'un des pôles voit le déverrouillage de son propre dispositif de déverrouillage.In addition, as mentioned previously when the device of the present invention is applied as a multipole switch with parallel poles, it makes it possible to cause, by a simple system, the unlocking of the locking device of all the parallel poles when one of the poles sees the unlocking. its own unlocking device.

Les figures 10 à 12 représentent encore un autre mode de réalisation d'un dispositif de commande selon la présente invention, la figure 10 représentant l'élément de transmission dans sa première position enclenchée, la figure 11 représentant l'élément de transmission dans sa deuxième position déclenchée et la figure 12 représentant l'élément de transmission dans sa troisième position de réenclenchement.Figures 10 to 12 show yet another embodiment of a control device according to the present invention, Figure 10 showing the transmission element in its first engaged position, Figure 11 showing the transmission element in its second triggered position and Figure 12 showing the transmission element in its third reset position.

En référence aux dessins et plus particulièrement aux figures 1 à 3, on a représenté un dispositif, montable dans un bâti 1, de commande du déplacement d'un bras 2 entre au moins deux positions, une première position dite d'arrêt représentée aux figures 2 et 3 et une deuxième position dite de service, représentée à la figure 1, comprenant avantageusement un moyen de rappel 3 constitué dans l'exemple représenté par un ressort, dudit bras 2 vers la première position d'arrêt.Referring to the drawings and more particularly to Figures 1 to 3, there is shown a device, mountable in a frame 1, for controlling the movement of an arm 2 between at least two positions, a first so-called stop position shown in the figures. 2 and 3 and a second so-called service position, represented in FIG. 1, advantageously comprising a return means 3 constituted in the example represented by a spring, from said arm 2 towards the first stop position.

Selon la présente invention, ce dispositif comprend un organe 4 déplaçable en translation et/ou en rotation dans le plan de déplacement du bras, de commande du bras 2 par l'intermédiaire d'un élément de transmission 5, constitué avantageusement dans l'exemple représenté par l'extrémité 5b d'une biellette de transmission, prenant appui en 6 sur le bras 2 de manière librement coulissante pour permettre le déplacement de l'élément de transmission 5 le long du bras 2 et dans son plan de déplacement et entre au moins trois positions distinctes, avantageusement non alignées, une première position dite enclenchée représentée à la figure 1 pour laquelle le bras 2 est dans la position de service, une deuxième position dite déclenchée représentée à la figure 2 et une troisième position dite de réenclenchement ou d'armement représentée à la figure 3 pour lesquelles deuxième et troisième positions le bras 2 est dans la position d'arrêt. Ce dispositif de commande comprend en outre un dispositif de verrouillage 7 coopérant avec l'élément de transmission 5 en étant solidaire de celui-ci déplaçable entre au moins deux positions, une première position dite verrouillée autorisant le déplacement de l'élément de transmission 5 entre les première et troisième positions enclenchée et de réenclenchement mais empêchant l'élément de transmission de se déplacer vers sa deuxième position déclenchée par action sur l'organe de commande 4; et une deuxième position dite «déverrouillée» représentée à la figure 2 d'une part provoquant l'autorisation de déplacement dudit élément de transmission 5 vers sa deuxième position déclenchée, et d'autre part ne permettant audit élément de transmission de revenir à sa première position enclenchée qu'en passant obligatoirement par la troisième position de réenclenchement obtenue par le retour de l'organe de commande 4 à sa position hors fonctionnement représentée à la figure 3, ledit dispositif de verrouillage 7 reprenant par ailleurs sa position verrouillée lorsque l'élément de transmission est déplacé vers sa troisième position de réenclenchement comme on peut le voir clairement à partir de la figure 3.According to the present invention, this device comprises a member 4 movable in translation and / or in rotation in the plane of movement of the arm, for controlling the arm 2 by means of a transmission element 5, advantageously constituted in the example represented by the end 5b of a transmission link, bearing at 6 on the arm 2 in a freely sliding manner to allow the movement of the transmission element 5 along the arm 2 and in its plane of movement and between the at least three distinct positions, advantageously not aligned, a first so-called engaged position shown in FIG. 1 for which the arm 2 is in the service position, a second so-called triggered position shown in FIG. 2 and a third position called reclosing or d armament shown in Figure 3 for which second and third positions the arm 2 is in the stop position. This control device further comprises a locking device 7 cooperating with the transmission element 5 by being integral with the latter movable between at least two positions, a first so-called locked position authorizing the movement of the transmission element 5 between the first and third positions engaged and reset but preventing the transmission element from moving to its second position triggered by action on the control member 4; and a second position known as “unlocked” represented in FIG. 2 on the one hand causing the authorization to move said transmission element 5 to its second triggered position, and on the other hand not allowing said transmission element to return to its first engaged position that necessarily passing through the third reset position obtained by the return of the control member 4 to its non-operating position shown in Figure 3, said locking device 7 also resumes its locked position when the element transmission is moved to its third reset position as can be clearly seen from Figure 3.

Selon le mode de réalisation représenté aux figures 1 à 3, le dispositif selon la présente invention est appliqué comme interrupteur et dans ce cas le bras 2 est électriquement conducteur et comprend à son extrémité libre 2a un plot de contact 8 coopérant dans la deuxième position de service représentée à la figure 1 avec un élément de contact 9 fixe comportant un plot de contact 10 correspondant et électriquement conducteur.According to the embodiment shown in Figures 1 to 3, the device according to the present invention is applied as a switch and in this case the arm 2 is electrically conductive and comprises at its free end 2a a contact pad 8 cooperating in the second position of service represented in FIG. 1 with a fixed contact element 9 comprising a corresponding contact pad 10 and electrically conductive.

Le dispositif selon la présente invention comprend avantageusement un moyen de déclenchement automatique MDA du dispositif de verrouillage 7 pour l'amener dans la position déclenchée représentée à la figure 2. Selon un mode de réalisation particulier, le dispositif de verrouillage 7 comprend un élément allongé 13 prenant appui, dans la position enclenchée de l'élément de transmission 5 représentée à la figure 1, à une extrémité 13a contre une butée d'arrêt 14 tandis que l'autre extrémité 13b est solidaire de l'élément de transmission 5.The device according to the present invention advantageously comprises an automatic triggering means MDA of the locking device 7 to bring it into the triggered position shown in FIG. 2. According to a particular embodiment, the locking device 7 comprises an elongated element 13 bearing, in the engaged position of the transmission element 5 shown in Figure 1, at an end moth 13a against a stopper 14 while the other end 13b is integral with the transmission element 5.

Dans le cas d'application du dispositif comme interrupteur, le moyen de déclenchement automatique MDA est constitué de préférence par un déclencheur de type thermique, tel qu'une bilame, ou du type électromagnétique. Le déclencheur automatique MDA peut être valablement réalisé par tout moyen mécanique exerçant un effort sur l'extrémité 13a et qui provoquera le déclenchement du dispositif de verrouillage 7 lorsqu'un déplacement, une pression, une température ou une mesure d'une grandeur quelconque dépasseront une valeur prédéterminée.In the case of application of the device as a switch, the automatic triggering means MDA preferably consists of a trigger of the thermal type, such as a bimetallic strip, or of the electromagnetic type. The automatic trigger MDA can be validly produced by any mechanical means exerting a force on the end 13a and which will cause the triggering of the locking device 7 when a displacement, a pressure, a temperature or a measurement of any magnitude exceeds a predetermined value.

Selon une autre caractéristique de ce dispositif selon la présente invention, l'extrémité 5b de la biellette constituant l'élément de transmission 5 prend appui par contact roulant ou glissant en 6 sur le bras 2 tandis que l'autre extrémité 5a coopérant avec l'organe de commande 4 est articulée en 11 sur l'organe de commande 4. Dans l'exemple représenté notamment aux figures 1 à 3, la biellette prend appui par contact roulant en comportant à son extrémité 5b constituant l'élément de transmission 5 une roulette 12 qui, dans l'application comme interrupteur, est avantageusement isolante.According to another characteristic of this device according to the present invention, the end 5b of the link constituting the transmission element 5 bears by rolling or sliding contact at 6 on the arm 2 while the other end 5a cooperating with the control member 4 is articulated at 11 on the control member 4. In the example shown in particular in Figures 1 to 3, the link is supported by rolling contact with at its end 5b constituting the transmission element 5 a roller 12 which, in the application as a switch, is advantageously insulating.

On doit noter que selon une autre caractéristique de ce dispositif, le bras 2 est incliné par rapport à la biellette selon un angle d'inclinaison prédéterminé de manière que le bras forme un chemin de roulement ou de glissement pour l'élément de transmission 5 de la biellette de façon que l'élément de transmission 5 ait normalement tendance à rouler ou glisser sur le bras 2 en cas de verrouillage du dispositif de verrouillage 7 comme on peut le voir en comparant les positions des figures 1 et 2.It should be noted that according to another characteristic of this device, the arm 2 is inclined relative to the link at a predetermined angle of inclination so that the arm forms a rolling or sliding path for the transmission element 5 of the link so that the transmission element 5 normally has a tendency to roll or slide on the arm 2 in the event of the locking of the locking device 7 as can be seen by comparing the positions of FIGS. 1 and 2.

Selon une autre caractéristique de ce dispositif, le bras 2 est monté pivotant et coulissant à l'une 2b de ses extrémités 2a, 2b dans une encoche 16 réalisée dans le bâti 1, le moyen de rappel 3 du bras 2 repoussant le bras 2 vers le fond 17 de l'encoche 16 de façon à permettre ensuite l'ouverture des contacts lorsque l'élément de transmission 5 ne prend pas appui sur le bras 2 comme on le voit bien à partir des figures 1 et 2 notamment. On doit noter que cette caractéristique de construction est intéressante pour compenser les jeux de montage ou l'usure des contacts provoqués par la coupure du courant. On peut également noter que d'autres formes de bras de contact peuvent être réalisées. On peut citer par exemple une lame flexible élastique ou un pont de contact comme celui représenté à la figure 9 et qui sera décrit plus loin.According to another characteristic of this device, the arm 2 is pivotally mounted and sliding at one 2b of its ends 2a, 2b in a notch 16 produced in the frame 1, the return means 3 of the arm 2 pushing the arm 2 towards the bottom 17 of the notch 16 so as to then allow the opening of the contacts when the transmission element 5 is not supported on the arm 2 as can be seen from Figures 1 and 2 in particular. It should be noted that this construction characteristic is advantageous for compensating for assembly play or wear of the contacts caused by the power cut. It can also be noted that other forms of contact arm can be produced. Mention may be made, for example, of an elastic flexible blade or a contact bridge such as that shown in FIG. 9 and which will be described later.

Par ailleurs, selon une autre caractéristique avantageuse, ce dispositif comprend en outre un moyen de rappel 18, notamment élastique, tel qu'un ressort, de l'organe de commande 4 dans la position initiale hors fonctionnement pour laquelle le bras 2 est dans la première position d'arrêt. Dans l'exemple représenté aux figures 1 à 3, notamment, l'organe de commande 4 est constitué par une manette montée pivotante sur un axe 20 de position fixe.Furthermore, according to another advantageous characteristic, this device further comprises a return means 18, in particular elastic, such as a spring, of the control member 4 in the initial non-operating position for which the arm 2 is in the first stop position. In the example shown in Figures 1 to 3, in particular, the control member 4 is constituted by a lever pivotally mounted on an axis 20 of fixed position.

Selon encore une autre caractéristique de ce dispositif, l'extrémité 13b de l'élément allongé 13 solidaire de l'élément de transmission 5 est articulée en 21 sur l'élément de transmission 5.According to yet another characteristic of this device, the end 13b of the elongate element 13 secured to the transmission element 5 is articulated at 21 on the transmission element 5.

Selon l'exemple représenté aux figures 1 à 3, la butée d'arrêt 14 est fixe et est formée par un épaulement 22 contre lequel vient buter l'extrémité correspondante 13a de l'élément allongé 13.According to the example shown in FIGS. 1 to 3, the stopper 14 is fixed and is formed by a shoulder 22 against which the corresponding end 13a of the elongate element 13 abuts.

Par ailleurs, pour permettre un bon fonctionnement de ce dispositif, celui-ci comprend diverses butées 24, 25, 26, des moyens de guidage 27, 28 limitant et guidant le déplacement de chacune des pièces précitées du dispositif selon la présente invention. En outre, l'élément allongé 13 peut comporter avantageusement un prolongement 30 éventuellement élastique formant profil de came permettant par coopération avec l'une des butées et/ou l'un des moyens de guidage précités lors du déplacement de l'organe de commande 4 de la deuxième position de service précitée à la première position d'arrêt précitée de ramener l'extrémité opposée libre 13a de l'élément allongé 13 en position enclenchée comme on le voit bien à la figure 3. Le fonctionnement de ce dispositif représenté aux figures 1 à 3 est particulièrement simple et le suivant:Furthermore, to allow proper operation of this device, it comprises various stops 24, 25, 26, guide means 27, 28 limiting and guiding the movement of each of the aforementioned parts of the device according to the present invention. In addition, the elongate element 13 may advantageously include an optionally elastic extension 30 forming a cam profile allowing, by cooperation with one of the abutments and / or one of the aforementioned guide means during the movement of the control member 4 from the aforementioned second service position to the aforementioned first stop position to bring the free opposite end 13a of the elongated element 13 into the engaged position as can be seen in FIG. 3. The operation of this device shown in the figures 1 to 3 is particularly simple and the following:

Le dispositif de verrouillage 7 étant verrouillé comme représenté à la figure 1, par déplacement de l'organe de commande 4 en position de fonctionnement représentée à la figure 1, l'élément de transmission 5 de la biellette de transmission, guidé par le dispositif de verrouillage 7, fait pivoter le bras 2 jusqu'à l'amener en position d'appui forcé contre l'élément de contact 9 en fermant le circuit de courant. On doit noter que dans cette position de service le point d'articulation 11 entre l'élément de transmission 5 et l'organe de commande 4 a dépassé la droite d passant par le point d'appui 6 de la biellette de transmission sur le bras 2 et par l'axe d'articulation 20 de l'organe de commande 4 ce qui permet de maintenir l'organe de commande 4 dans sa position de fonctionnement correspondant à la position de service du bras 2. Par ailleurs, on doit noter que le dispositif est à déclenchement libre étant donné que même lorsque l'organe de commande 4 est bloqué dans la position en fonctionnement représentée à la figure 1, on a la sécurité d'obtenir l'ouverture du circuit sous l'action prédéterminée du moyen de déclenchement automatique MDA car il se produit alors le soulèvement de l'extrémité 13a de l'élément allongé 13 et sous l'effet du moyen de rappel 3 du bras 2 le déplacement de l'élément de transmission 5 et donc de la biellette pour aboutir à la position déclenchée représentée à la figure 2 pour laquelle le circuit de courant est ouvert.The locking device 7 being locked as shown in FIG. 1, by displacement of the control member 4 in the operating position shown in FIG. 1, the transmission element 5 of the transmission link, guided by the locking 7, pivots the arm 2 until it brings it into the forced support position against the contact element 9 by closing the current circuit. It should be noted that in this service position the point of articulation 11 between the transmission element 5 and the control member 4 has exceeded the straight line d passing through the fulcrum 6 of the transmission link on the arm 2 and by the hinge pin 20 of the control member 4 which makes it possible to maintain the control member 4 in its operating position corresponding to the operating position of the arm 2. Furthermore, it should be noted that the device is freely triggered since even when the control member 4 is locked in the operating position shown in FIG. 1, it is safe to obtain the opening of the circuit under the predetermined action of the means of MDA automatic triggering because the end 13a of the elongated element 13 then rises and under the effect of the return means 3 of the arm 2 the displacement of the transmission element 5 and therefore of the link to achieve at the triggered position shown in fi gure 2 for which the current circuit is open.

On obtient donc tous les avantages mentionnés précédemment dans la partie introductive de la description.We therefore obtain all the advantages mentioned previously in the introductory part of the description.

En référence à la figure 4, on a représenté plusieurs dispositifs des figures 1 à 3 disposés en parallèle pour former un interrupteur multipolaire. Ainsi, il est prévu avantageusement dans ce cas divers moyens d'accouplement tels que 32 des organes de commande 4 entre eux. En outre, avantageusement, un arbre 34 pivotant unique est disposé près de l'extrémité libre 13a de l'élément allongé 13 de chaque dispositif de verrouillage 7 opposée à celle 13b solidaire de l'élément de transmission 5 et comprend des prolongement 36 associés auxdites extrémités 13a en un nombre égal au nombre d'éléments allongés 13, susceptibles par un déplacement relatif des éléments allongés 13 avec les butées d'arrêt 14 avec lesquelles ils coopèrent, de rompre l'appui des éléments allongés 13 contre les butées d'arrêt 14. Par ailleurs, cet arbre pivotant 34 est pourvu d'une lamelle rigide 35 dans l'axe de débattement ou de déclenchement de chaque élément allongé 13 de manière que lorsqu'un élément allongé 13 est déclenché, ledit élément déclenché agit sur sa lamelle associée 35 et entraîne le pivotement de l'arbre pivotant 34 et des prolongements 36 qui lui sont solidaires et qui provoquent à leur tour le déclenchement des autres dispositifs de verrouillage 7 de manière à couper complètement le circuit. Dans l'exemple représenté à la figure 4a, les butées 14 sont fixes et les prolongements 36 de l'arbre 34 passent sous la butée fixe 14 voisine pour pouvoir rompre l'appui de chaque extrémité 13a de l'élément allongé 13 contre la butée d'arrêt 14.Referring to Figure 4, there are shown several devices of Figures 1 to 3 arranged in parallel to form a multipole switch. Thus, it is advantageously provided in this case various coupling means such as 32 of the control members 4 between them. In addition, advantageously, a single pivoting shaft 34 is disposed near the free end 13a of the elongated element 13 of each locking device 7 opposite to that 13b secured to the transmission element 5 and comprises extensions 36 associated with said ends 13a in a number equal to the number of elongated elements 13, capable of a relative displacement of the elongated elements 13 with the stops 14 with which they cooperate, to break the support of the elongated elements 13 against the stops 14. Furthermore, this pivoting shaft 34 is provided with a rigid strip 35 in the axis of movement or triggering of each elongated element 13 so that when an elongated element 13 is triggered, said triggered element acts on its lamella associated 35 and drives the pivoting shaft 34 and the extensions 36 which are integral with it and which in turn cause the triggering of the other locking devices 7 so as to cut the circuit completely. In the example shown in FIG. 4a, the stops 14 are fixed and the extensions 36 of the shaft 34 pass under the adjacent fixed stop 14 in order to be able to break the support of each end 13a of the elongated element 13 against the stop stop 14.

Notamment, en référence à la figure 6, l'élément allongé 50 peut être monté pivotant selon un axe 51 de position fixe disposé en un point espacé de ses extrémités 50a et 50b de manière que son extrémité 50a opposée à celle 50b solidaire de l'élément de transmission 5 prenne appui en position verrouillée contre une butée 52 d'arrêt qui est dans l'exemple représenté mobile, comporte un épaulement 55 formant butée d'arrêt de l'élément 50 qui peut comporter par exemple un évidement correspondant 56, en position verrouillée. Dans ce cas, le moyen de déclenchement automatique MDA peut être avantageusement prévu pour actionner la butée d'arrêt 52 de façon à déverrouiller le dispositif de verrouillage 7. Selon une caractéristique particulière, l'extrémité 5b constituant l'élément de transmission 5 de la biellette peut être articulée de manière coulissante sur l'élément allongé 50 qui comprend à cet effet une rainure de coulissement 58. En traits fantômes est représentée la position de réenclenchement. Selon encore une autre variante de réalisation, représentée à la figure 5, l'organe de commande précité peut être constitué par un bouton-poussoir 60 déplaçable en translation dans une encoche 61 du bâti 1 et peut comporter à son extrémité 60a coopérant avec l'élément de transmission 5 deux épaulements 62, 63 formant saillie extérieurement disposés de part et d'autre de ladite extrémité 60a et de manière avantageusement symétrique, un épaulement 62 servant de point d'appui d'un moyen de rappel 64 de l'organe de commande dans la première position d'arrêt et l'autre épaulement 63 coopérant avec un évidement 65 correspondant du bâti 1 formant butée d'arrêt de l'organe de commande (bouton-poussoir 60) dans la deuxième position de service telle que représentée. On doit noter que la première position d'arrêt est représentée en traits fantômes. Par ailleurs, on prévoit une butée 66 sur laquelle prend appui l'élément de transmission 5 de la biellette de manière que lors du déverrouillage de l'élément allongé 13, sous l'effet du moyen de déclenchement automatique MDA, la butée 66 agisse sur l'élément de transmission 5 de manière à chasser l'épaulement 63 du bouton-poussoir 60 hors de l'évidement 65 et permettre ainsi la remontée du bouton-poussoir 60. Pour la fermeture du dispositif, la combinaison du moyen de rappel élastique 64, des moyens de guidage 28 et 66 et du prolongement 30 précité de l'élément allongé 13 permet d'amener l'élément allongé 13 en position verrouillée représentée en traits forts tout en amenant le bras 2 dans la deuxième position de service représentée en traits forts selon le principe de fonctionnement décrit pour les figures 1 à 4.In particular, with reference to FIG. 6, the elongated element 50 can be pivotally mounted along an axis 51 of fixed position disposed at a point spaced from its ends 50a and 50b so that its end 50a opposite to that 50b secured to the transmission element 5 takes support in the locked position against a stop 52 which is in the example shown movable, has a shoulder 55 forming a stop of the element 50 which can for example include a corresponding recess 56, in locked position. In this case, the automatic tripping means MDA can advantageously be provided to actuate the stopper 52 so as to unlock the locking device 7. According to a particular characteristic, the end 5b constituting the transmission element 5 of the rod can be hingedly slidably on the elongated element 50 which for this purpose comprises a sliding groove 58. In phantom lines is shown the reset position. According to yet another alternative embodiment, represented in FIG. 5, the aforementioned control member can be constituted by a push button 60 movable in translation in a notch 61 of the frame 1 and can comprise at its end 60a cooperating with the transmission element 5 two shoulders 62, 63 projecting outwardly arranged on either side of said end 60a and advantageously symmetrically, a shoulder 62 serving as a fulcrum of a return means 64 of the control in the first stop position and the other shoulder 63 cooperating with a corresponding recess 65 of the frame 1 forming a stop stop for the control member (push button 60) in the second service position as shown. It should be noted that the first stop position is shown in phantom lines. Furthermore, a stop 66 is provided on which the transmission element 5 of the connecting rod bears so that when the elongated element 13 is unlocked, under the effect of the automatic triggering means MDA, the stop 66 acts on the transmission element 5 so as to drive the shoulder 63 of the push-button 60 out of the recess 65 and thus allow the push-button 60 to be raised. To close the device, the combination of the elastic return means 64 , guide means 28 and 66 and the aforementioned extension 30 of the elongated element 13 makes it possible to bring the elongated element 13 to the locked position shown in strong lines while bringing the arm 2 into the second service position shown in lines strong according to the operating principle described for Figures 1 to 4.

Une autre variante de réalisation est représentée à la figure 7. Dans ce cas, l'élément de transmission constitué par une extrémité de la biellette de transmission précitée et le dispositif de verrouillage précité sont réalisés en une seule pièce monobloc constituée par une barre ayant en un endroit espacé de ses extrémités 100a, 100b un coude 101 élastique constituant l'élément de transmission servant de point d'appui de l'ensemble 100 biellette-dispositif de verrouillage sur le bras 2. La position déclenchée et déverrouillée est représentée en pointillés tandis que la position de réenclenchement est représentée en traits fantômes. Selon encore un autre mode de réalisation particulier de la figure 9, l'élément de transmission précité est constitué par une extrémité de la biellette de transmission précitée, le dispositif de verrouillage et l'organe de commande peuvent être constitués par une seule pièce monobloc 70 constituée par une barre ayant en un endroit espacé de ses extrémités 70a, 70b un coude 71 élastique. Ainsi, on peut considérer que le coude 71 constitue l'élément de transmission, l'extrémité 70a de la pièce monobloc 70 constitue le dispositif de verrouillage, l'extrémité 70b constituant la biellette de transmission dont la partie extrême constitue l'organe de commande 70c formé par un bouton-poussoir déplaçable en translation dans le bâti 72. Le bouton-poussoir comprend avantageusement un épaulement 73 coopérant avec un profil correspondant 74 du bâti 72, un moyen de rappel élastique 75 étant avantageusement prévu pour repousser le bouton-poussoir de la pièce monobloc 70 vers la position de réenclenchement représentée en traits fantômes.Another alternative embodiment is shown in FIG. 7. In this case, the transmission element constituted by one end of the aforementioned transmission link and the aforementioned locking device are produced in a single piece consisting of a bar having in a place spaced from its ends 100a, 100b an elastic bend 101 constituting the transmission element serving as the fulcrum of the assembly 100 link-locking device on the arm 2. The triggered and unlocked position is shown in dotted lines while that the reset position is shown in phantom lines. According to yet another particular embodiment of FIG. 9, the aforementioned transmission element is constituted by one end of the aforementioned transmission link, the locking device and the control member can be constituted by a single piece 70 constituted by a bar having at a location spaced from its ends 70a, 70b an elastic bend 71. Thus, it can be considered that the elbow 71 constitutes the transmission element, the end 70a of the single piece 70 constitutes the locking device, the end 70b constituting the transmission link, the end part of which constitutes the control member. 70c formed by a push button movable in translation in the frame 72. The push button advantageously comprises a shoulder 73 cooperating with a corresponding profile 74 of the frame 72, an elastic return means 75 being advantageously provided for pushing the push button from the single piece 70 to the reset position shown in phantom lines.

En référence à la figure 8, on a représenté un autre mode de réalisation selon lequel le bras 110 est monté en pont entre deux bords 111, 112 du bâti et comprend deux plots 113, 114 de contact avec deux éléments de contact correspondants 115, 116, respectivement. Le bras 110 est repoussé vers les bords 111, 112, sous l'effet d'un moyen de rappel élastique 117 tel qu'un ressort. Selon une caractéristique particulière de ce mode de réalisation, la biellette de transmission précitée peut comprendre un corps 118 creux dans lequel coulisse une tige 119 comportant une collerette 120 de retenue d'un ressort 121 tendant à repousser la tige 119 hors dudit corps creux 118. La collerette 120 sert également de butée de coulissement de la tige 119 dont l'extrémité libre 119a constitue en fait l'élément de transmission précité prenant appui sur ledit bras 110.Referring to Figure 8, there is shown another embodiment according to which the arm 110 is mounted in a bridge between two edges 111, 112 of the frame and comprises two contact pads 113, 114 with two corresponding contact elements 115, 116 , respectively. The arm 110 is pushed back towards the edges 111, 112, under the effect of an elastic return means 117 such as a spring. According to a particular characteristic of this embodiment, the aforementioned transmission link tee may comprise a hollow body 118 in which slides a rod 119 comprising a collar 120 for retaining a spring 121 tending to push the rod 119 out of said hollow body 118. The collar 120 also serves as a sliding stop for the rod 119 whose the free end 119a in fact constitutes the aforementioned transmission element bearing on said arm 110.

D'autre part, l'élément allongé précité du dispositif de verrouillage 7 peut être constitué avantageusement par une barre 125 coudée en 126 à un endroit espacé de ses extrémités de manière que le ressort 121 interne au corps creux 118 de la biellette de transmission compense avec le cou- dage élastique 126 l'action du moyen de rappel 117. On doit noter également dans ce cas que dans la position de service représentée en traits forts, l'articulation 11 du corps creux 118 à l'organe de commande 4 est située au-delà de la droite d passant par l'axe d'articulation 20 de l'organe de commande 4 et le point d'articulation 21 de la roulette 12. Dans ce cas, le ressort 121 permet d'exercer une pression sur les plots de contact 113, 114 afin de compenser leur usure étant donné qu'il agit à l'encontre du moyen de rappel 117. Ce mode de réalisation permet en outre une ouverture plus rapide des contacts. En référence aux figures 10 à 12, selon encore une autre variante de réalisation, l'organe de commande précité est constitué par un bouton-poussoir 200 déplaçable en translation dans une encoche 199 du bâti, lequel bouton-poussoir 200 comprend à son extrémité coopérant avec l'élément de transmission 201 précité une fente 202 que l'on voit bien à la figure 11 disposée sensiblement perpendiculairement à l'axe de translation X-X du bouton-poussoir 200. L'élément de transmission 201 est constitué par un axe de transmission logé dans la fente 202 et passant par ailleurs à travers une rainure 203 réalisée dans la masse du bras 2' et le long du bras 2' d'une distance prédéterminée. Le dispositif de verrouillage 204 comprend un élément allongé comprenant une partie 205 en forme de tige dont le déplacement est guidé entre deux séries de butées fixes 206, 207; 208, 209, la butée d'arrêt 210 précitée de l'extrémité de la partie 205 opposée à celle coopérant avec l'élément de transmission 201 est mobile et prévue actionnée par le moyen de déclenchement automatique MDA pour déverrouiller le dispositif de verrouillage 204.On the other hand, the above-mentioned elongated element of the locking device 7 can advantageously consist of a bar 125 bent at 126 at a location spaced from its ends so that the spring 121 internal to the hollow body 118 of the transmission link compensates with the elastic bending 126 the action of the return means 117. It should also be noted in this case that in the service position shown in strong lines, the joint 11 of the hollow body 118 to the control member 4 is located beyond the straight line d passing through the articulation axis 20 of the control member 4 and the articulation point 21 of the caster 12. In this case, the spring 121 makes it possible to exert pressure on the contact pads 113, 114 in order to compensate for their wear since it acts against the return means 117. This embodiment also allows faster opening of the contacts. With reference to FIGS. 10 to 12, according to yet another alternative embodiment, the aforementioned control member consists of a push button 200 displaceable in translation in a notch 199 of the frame, which push button 200 comprises at its cooperating end with the aforementioned transmission element 201 a slot 202 which can be seen clearly in FIG. 11 arranged substantially perpendicular to the axis of translation XX of the push button 200. The transmission element 201 is constituted by a transmission axis housed in the slot 202 and also passing through a groove 203 made in the mass of the arm 2 'and along the arm 2' from a predetermined distance. The locking device 204 comprises an elongated element comprising a rod-shaped part 205 whose movement is guided between two series of fixed stops 206, 207; 208, 209, the abovementioned stop 210 at the end of the part 205 opposite to that cooperating with the transmission element 201 is mobile and provided actuated by the automatic release means MDA to unlock the locking device 204.

Selon une caractéristique particulière, le dispositif de verrouillage 204 a son élément allongé qui comprend à son extrémité solidaire de l'élément de transmission 201 une partie 211 recourbée le long du bouton-poussoir 200 et comportant une saignée 212 dans laquelle pénètre l'élément de transmission, disposée principalement sensiblement parallèlement à l'axe X-X de translation du bouton-poussoir 200 et ayant un prolongement 212a de forme appropriée disposée généralement sensiblement perpendiculairement à l'axe de translation X-X.According to a particular characteristic, the locking device 204 has its elongated element which comprises at its end integral with the transmission element 201 a part 211 curved along the push-button 200 and comprising a groove 212 into which the element of transmission, disposed mainly substantially parallel to the axis XX of translation of the push button 200 and having an extension 212a of suitable shape generally arranged substantially perpendicular to the axis of translation XX.

Selon l'exemple représenté, le bouton-poussoir 200 comprend à son extrémité coopérant avec l'élément de transmission 201 une encoche centrale définissant deux joues d'extrémité au bouton-poussoir 200, la fente 202 précitée du bouton-poussoir 200 étant réalisée sur chaque joue de manière que l'axe de transmission constituant l'élément de transmission 201 traverse de part en part lesdites joues en passant dans ladite encoche et avantageusement fasse saillie extérieurement du profil du bouton-poussoir 200. Par ailleurs, le bras 2' dans la rainure 203 duquel passe l'élément de transmission 201 est logé dans ladite encoche de manière librement pivotante comme on le conçoit bien à partir des figures 10 à 12.According to the example shown, the push button 200 comprises at its end cooperating with the transmission element 201 a central notch defining two end cheeks to the push button 200, the aforementioned slot 202 of the push button 200 being produced on each cheek so that the transmission axis constituting the transmission element 201 passes right through said cheeks passing through said notch and advantageously protrudes externally from the profile of the push button 200. Furthermore, the arm 2 ′ in the groove 203 from which the transmission element 201 passes is housed in said notch in a freely pivoting manner as is well understood from FIGS. 10 to 12.

En outre, la partie recourbée 211 de l'élément allongé comprend deux flasques dont on voit le flasque 211a, disposés de part et d'autre extérieurement du bouton-poussoir, chaque flasque comportant la saignée 212 précitée, les parties en saillie de l'élément de transmission 201 pénétrant dans la saignée 212 de chaque flasque.In addition, the curved part 211 of the elongated element comprises two flanges, the flange 211a of which can be seen, arranged on either side externally of the push button, each flange comprising the above-mentioned groove 212, the protruding parts of the transmission element 201 penetrating into the groove 212 of each flange.

Le fonctionnement de ce dispositif est particulièrement simple.The operation of this device is particularly simple.

A partir de la troisième position de réenclenchement représentée à la figure 12, par action sur le bouton-poussoir 200 dans le sens de la flèche représentée à la figure 12 l'élément de transmission 201 est amené à coulisser dans la rainure 203 et dans la saignée 212 jusqu'à aboutir dans son prolongement 212a pour aboutir à la position enclenchée représentée à la figure 10 pour laquelle le bras 2' est en position de service. Lors du déverrouillage du dispositif de verrouillage 204 sous l'effet du moyen de déclenchement automatique MDA et sous l'effet des divers moyens de rappel tels que le ressort 3, l'élément allongé du dispositif de verrouillage se déplace vers la droite dans le sens de la flèche R représentée à la figure 11 et l'élément de transmission 201 se déplace dans la fente 202 du bouton-poussoir jusqu'à aboutir à la position représentée à la figure 11 pour laquelle l'élément de transmission 201 est dans la deuxième position déclenchée précitée. Lorsque l'élément de transmission 201 bute contre le bord latéral de la fente 202, il se produit un léger choc avec l'arrêt concomitant du mouvement vers la droite du dispositif de verrouillage 204 amenant l'élément de transmission 201 à quitter le prolongement 212a de la saignée 212 pour revenir dans la saignée 212 proprement dite en libérant ainsi le bouton-poussoir 200 qui remonte en position hors fonctionnement comme représenté à la figure 12, l'élément de transmission 201 étant alors revenu dans sa troisième position de réenclenchement, lequel mouvement a ramené le dispositif de verrouillage 204 en position verrouillée comme on le voit bien à la figure 12.From the third reset position shown in FIG. 12, by pressing the push button 200 in the direction of the arrow shown in FIG. 12 the transmission element 201 is caused to slide in the groove 203 and in the groove 212 until reaching in its extension 212a to reach the engaged position shown in Figure 10 for which the arm 2 'is in the service position. When unlocking the locking device 204 under the effect of the automatic release means MDA and under the effect of various return means such as the spring 3, the elongated element of the locking device moves to the right in the direction of the arrow R represented in FIG. 11 and the transmission element 201 moves in the slot 202 of the push-button until reaching the position represented in FIG. 11 for which the transmission element 201 is in the second above triggered position. When the transmission element 201 abuts against the lateral edge of the slot 202, a slight shock occurs with the concomitant stop of the movement to the right of the locking device 204 causing the transmission element 201 to leave the extension 212a from the recess 212 to return to the recess 212 proper, thereby releasing the push button 200 which rises to the non-operating position as shown in FIG. 12, the transmission element 201 then having returned to its third reset position, which movement brought the locking device 204 back to the locked position as can be seen in FIG. 12.
