Description

La présente invention concerne un dispositif de verrouillage de la commande d'un appareil électrique à commande manuelle.The present invention relates to a device for locking the control of an electrical appliance with manual control.

On sait que pour certains appareils électriques à commande manuelle, notamment des interrupteurs disposés sur l'alimentation en puissance d'un réseau, il peut être souhaitable de maintenir la commande dans une position prédéterminée, en particulier pour des raisons de sécurité.It is known that for certain electrical devices with manual control, in particular switches arranged on the power supply of a network, it may be desirable to maintain the control in a predetermined position, in particular for safety reasons.

On connait des dispositifs permettant d'effectuer le verrouillage de la commande manuelle d'un appareil électrique. Toutefois, ces dispositifs ne permettent généralement pas la mise en place aisée et efficace d'un cadenas ou d'un plombage. Certains d'entre eux peuvent en effet recevoir un cadenas, mais leur structure est telle qu'un verrouillage effectif ne peut être obtenu par un simple plombage. D'autres au contraire peuvent recevoir un plombage efficace, mais ne permettent pas la mise en place d'un cadenas.Devices are known for effecting the locking of the manual control of an electrical appliance. However, these devices generally do not allow the easy and effective installation of a padlock or a seal. Some of them can indeed receive a padlock, but their structure is such that an effective locking cannot be obtained by a simple sealing. Others on the contrary can receive an effective sealing, but do not allow the installation of a padlock.

Un but de la présente invention est de réaliser un dispositif de verrouillage de la commande d'un appareil électrique à commande manuelle, ayant une structure simple et permettant un verrouillage effectif, aussi bien avec un cadenas qu'avec un simple fil plombé.An object of the present invention is to provide a device for locking the control of an electric device with manual control, having a simple structure and allowing effective locking, both with a padlock and with a simple leaded wire.

En vue de la réalisation de ce but, on prévoit selon l'invention un dispositif de verrouillage de la commande d'un appareil électrique à commande manuelle, caractérisé en ce qu'il comprend deux parties articulées l'une à l'autre par des moyens d'articulation, des moyens d'accrochage disposés le long d'un bord espacé des moyens d'articulation, au moins une surface de butée portée par l'une des parties, et au moins une ouverture de verrouillage formée dans chacune des parties et disposée pour venir en regard de l'ouverture de verrouillage correspondante de l'autre partie lorsque le dispositif est en position de verrouillage.With a view to achieving this goal, there is provided according to the invention a device for locking the control of an electric apparatus with manual control, characterized in that it comprises two parts articulated to one another by articulation means, hooking means arranged along an edge spaced from the articulation means, at least one abutment surface carried by one of the parts, and at least one locking opening formed in each of the parts and arranged to come opposite the corresponding locking opening of the other part when the device is in the locking position.

Ainsi, pendant la mise en place du dispositif les deux parties sont inclinées l'une par rapport à l'autre autour des moyens d'articulation, la surface de butée est écartée de la commande manuelle qui peut être éventuellement manoeuvrée. Au contraire, lorsque le dispositif de verrouillage est mis en place avec les ouvertures de verrouillage en regard, la surface de butée empêche la manoeuvre de la commande manuelle. Le dispositif de verrouillage peut être maintenu en position de verrouillage soit par la tige d'un cadenas s'étendant à travers les ouvertures, soit par un fil passant par les ouvertures et serré contre le bord du dispositif de verrouillage par un plombage.Thus, during the installation of the device, the two parts are inclined relative to each other around the articulation means, the abutment surface is moved away from the manual control which can be optionally operated. On the contrary, when the locking device is put in place with the locking openings facing each other, the abutment surface prevents the operation of the manual control. The locking device can be held in the locking position either by the rod of a padlock extending through the openings, or by a wire passing through the openings and tightened against the edge of the locking device by a seal.

Selon une version avantageuse de l'invention, les moyens d'articulation entre les parties adjacentes sont en saillie par rapport aux surfaces de butée lorsque le dispositif est en position de verrouillage. Ainsi, l'appui du dispositif de verrouillage sur la commande manuelle se trouve renforcé.According to an advantageous version of the invention, the articulation means between the adjacent parts protrude relative to the abutment surfaces when the device is in the locked position. Thus, the support of the locking device on the manual control is reinforced.

Selon une version préférée du dispositif de verrouillage selon l'invention, les ouvertures de verrouillage sont formées dans des ailes, chacune articulée à l'une des parties adjacentes.According to a preferred version of the locking device according to the invention, the locking openings are formed in wings, each articulated to one of the adjacent parts.

Ainsi, le dispositif de verrouillage peut être fabriqué à plat et les ouvertures de verrouillage sont mises en regard par une rotation des ailes autour de leur moyen d'articulation.Thus, the locking device can be manufactured flat and the locking openings are brought into facing by a rotation of the wings around their articulation means.

Selon une autre caractéristique de la version préférée de l'invention, au moins l'une des ailes comporte. un téton de positionnement s'étendant transversalement au plan de l'aile, et l'autre aile comporte un trou correspondant pour recevoir le téton de positionnement lorsque le dispositif est en position de verrouillage. Ainsi, en faisant pénétrer le téton de positionnement d'une aile dans le trou correspondant de l'autre aile, on assure un positionnement du dispositif de verrouillage avant la mise en place des moyens de maintien tels que le cadenas ou le fil plombé.According to another characteristic of the preferred version of the invention, at least one of the wings comprises. a positioning stud extending transversely to the plane of the wing, and the other wing has a corresponding hole for receiving the positioning stud when the device is in the locking position. Thus, by penetrating the positioning pin of a wing in the corresponding hole of the other wing, the locking device is positioned before the holding means such as the padlock or the lead wire are put in place.

Selon un autre aspect de l'invention, les ouvertures de verrouillage sont obturées par une cloison fragile suivant une direction transversale à son plan et résistante selon une direction sensiblement parallèle à son plan, et de préférence, la cloison comporte des rainures d'affaiblissement. Ainsi, on peut découper la cloison selon une ouverture exactement appropriée à la section des moyens de maintien.According to another aspect of the invention, the locking openings are closed by a fragile partition in a direction transverse to its plane and resistant in a direction substantially parallel to its plane, and preferably, the partition has weakening grooves. Thus, the partition can be cut out according to an opening exactly suitable for the section of the holding means.

En référence aux figures, le dispositif de verrouillage selon l'invention comporte deux parties 1, articulées l'une à l'autre par des moyens d'articulation 2, des moyens d'accrochage, formés ici par des ergots 3 en saillie par rapport aux extrémités des parties 1, sont disposés le long d'un bord espacé des moyens d'articulation 2. Dans le mode de réalisation représenté, chaque partie 1 porte une surface de butée 4 et comporte trois ouvertures 5 de verrouillage qui viennent en regard des ouvertures de verrouillage correspondantes de l'autre partie lorsque le dispositif est dans une position de verrouillage (figures 5, 6).With reference to the figures, the locking device according to the invention comprises two parts 1, articulated to each other by articulation means 2, attachment means, formed here by lugs 3 projecting from at the ends of parts 1, are arranged along an edge spaced from the articulation means 2. In the embodiment shown, each part 1 carries a stop surface 4 and has three locking openings 5 which come opposite the corresponding locking openings of the 'other part when the device is in a locking position (Figures 5, 6).

Les moyens d'articulation 2, formés par une paroi mince en forme de pont réunissant les parties 1, font saillie par rapport aux surfaces de butée 4 (figures 5, 6).The articulation means 2, formed by a thin wall in the form of a bridge joining the parts 1, protrude relative to the abutment surfaces 4 (FIGS. 5, 6).

Les ouvertures de verrouillage 5 sont formées dans des ailes 6, chacune articulée par une charnière 7 à l'une des parties 1 adjacentes.The locking openings 5 are formed in wings 6, each articulated by a hinge 7 to one of the adjacent parts 1.

Dans le mode de réalisation représenté, chacune des ailes 6 comporte un téton 8 de positionnement, s'étendant transversalement au plan de l'aile 6 et un trou 9 correspondant au téton de positionnement 8 dans l'autre aile pour recevoir ce téton de positionnement lorsque le dispositif est en position de verrouillage.In the embodiment shown, each of the wings 6 comprises a positioning stud 8, extending transversely to the plane of the wing 6 and a hole 9 corresponding to the positioning stud 8 in the other wing to receive this positioning stud when the device is in the locked position.

La figure 5 illustre une variante de réalisation du dispositif dans laquelle les ouvertures de verrouillage 5 sont obturées par une cloison mince 10, comportant des rainures d'affaiblissement 11, de sorte que la cloison 10 est fragile suivant une direction transversale à son plan et relativement résistante selon une direction sensiblement parallèle à son plan.FIG. 5 illustrates an alternative embodiment of the device in which the locking openings 5 are closed by a thin partition 10, having weakening grooves 11, so that the partition 10 is fragile in a direction transverse to its plane and relatively resistant in a direction substantially parallel to its plane.

A titre d'exemple, le dispositif de verrouillage selon l'invention a été réalisé en une matière plastique, plus particulièrement du polypropylène qui présente à la fois une rigidité suffisante pour que les parties 1 en forme de plaque et les ailes 6 soient rigides, et également une souplesse suffisante pour qu'une paroi mince constituée dans ce matériau soit souple afin de réaliser les charnières 2 et 7. Le dispositif a ainsi pu être moulé en une seule pièce. Sa fabrication est donc rapide et peu onéreuse.By way of example, the locking device according to the invention has been made of a plastic material, more particularly polypropylene which has both sufficient rigidity so that the plate-shaped parts 1 and the wings 6 are rigid, and also sufficient flexibility for a thin wall made of this material to be flexible in order to produce the hinges 2 and 7. The device could thus be molded in one piece. Its manufacture is therefore quick and inexpensive.

On a illustré sur les figures 4 et 5 la mise en place du dispositif de verrouillage selon l'invention sur un interrupteur dont le boîtier 12 comporte des logements 13 de forme sensiblement complémentaire à celle des ergots 3 du dispositif. L'interrupteur comporte en outre une commande manuelle basculante 14, encadrée par les logements 13.Illustrated in Figures 4 and 5 the establishment of the locking device according to the invention on a switch whose housing 12 has recesses 13 of shape substantially complementary to that of the pins 3 of the device. The switch further comprises a tilting manual control 14, framed by the housings 13.

Pour la mise en place du dispositif, les deux parties 1 sont inclinées l'une par rapport à l'autre autour de l'articulation 2, les ailes 6 étant dans une position quelconque, par exemple repliées sensiblement perpendiculairement aux parties 1, comme représenté sur la figure 4. Les ergots 3 sont alors introduits dans les logements 13, puis les parties 1 sont rabattues, tout en maintenant les ailes 6 sensiblement parallèles l'une à l'autre, jusqu'au moment où les encoches 5 de chaque aile 6 sont en coincidence. La commande 14 de l'interrupteur est ainsi en regard d'une surface de butée 4 et, dans le cas représenté sur la figure 5, du côté de la charnière 2 faisant saillie par rapport à la surface 4. Les ailes 6 sont alors plaquées l'une contre l'autre et le téton 8 d'une aile pénètre dans le trou 9 correspondant de l'autre aile de sorte que le dispositif est maintenu provisoirement en position de verrouillage. Le dispositif est ensuite maintenu plus fermement en position verrouillée, soit par l'introduction d'une ou plusieurs tiges de cadenas 15, d'un diamètre voisin de l'ouverture 5 qui a été pratiquée dans l'aile 6, soit au moyen d'un fil 16 maintenu serré dans une ouverture 5 par un plombage 17. On constate qu'en raison du faible jeu qui existe entre l'ouverture 5 et la tige de cadenas 15 ou entre la boucle du fil 16 et le rebord des ailes 6, les parties 1 ne peuvent pivoter que d'une quantité négligeable autour de la charnière 2 et toute tentative de manoeuvre de la commande manuelle 14 amène celle-ci en contact avec la surface de butée 4 et le côté de la charnière 2 sans qu'il soit possible de basculer complètement la commande 14. De plus, en bloquant la charnière 2 entre les parties 1, les moyens de verrouillage empêchent un arrachement du dispositif dont les ergots 3 ne peuvent être dégagés des logements 13.For the installation of the device, the two parts 1 are inclined relative to each other around the articulation 2, the wings 6 being in any position, for example folded substantially perpendicular to the parts 1, as shown in FIG. 4. The pins 3 are then introduced into the housings 13, then the parts 1 are folded down, while keeping the wings 6 substantially parallel to each other, until the notches 5 of each wing 6 are coincidental. The control 14 of the switch is thus opposite a stop surface 4 and, in the case shown in FIG. 5, on the side of the hinge 2 projecting relative to the surface 4. The wings 6 are then pressed one against the other and the stud 8 of one wing enters the corresponding hole 9 of the other wing so that the device is temporarily held in the locked position. The device is then held more firmly in the locked position, either by the introduction of one or more padlock rods 15, with a diameter close to the opening 5 which has been made in the wing 6, or by means of 'a wire 16 held tight in an opening 5 by a seal 17. It can be seen that due to the small clearance which exists between the opening 5 and the padlock rod 15 or between the loop of the wire 16 and the edge of the wings 6 , the parts 1 can only pivot by a negligible amount around the hinge 2 and any attempt to operate the manual control 14 brings the latter in contact with the abutment surface 4 and the side of the hinge 2 without it being possible to completely tilt the control 14. In addition, by blocking the hinge 2 between the parts 1, the locking means prevent the device from being torn off, the pins 3 of which cannot be released from the housings 13.

Dans la variante de réalisation de la figure 6, le dispositif de verrouillage selon l'invention est plus particulièrement adapté à un interrupteur comportant deux boutons poussoirs 18, 19 alternativement enfoncés ou sortis. Le dispositif comporte comme dans le mode de réalisation précédent deux parties 1, articulées autour d'une charnière 2 et supportant des ailes 6 dans lesquelles sont réalisées des ouvertures 5. Dans ce mode de réalisation, l'une des surfaces de butée 4 est en saillie par rapport au plan de l'autre surface de butée 4 et est disposée, lors de la mise en place du dispositif, en face du bouton 19 qui est en position enfoncée. Ainsi, indépendamment du fait que la partie 1 supérieure masque le bouton poussoir 18, celui-ci ne peut être manoeuvré car il entraînerait la sortie du bouton 19 qui viendrait alors en butée contre la surface de butée 4 correspondante.In the variant embodiment of FIG. 6, the locking device according to the invention is more particularly adapted to a switch comprising two push buttons 18, 19 alternately pressed in or out. As in the previous embodiment, the device comprises two parts 1, articulated around a hinge 2 and supporting wings 6 in which openings 5 are made. In this embodiment, one of the abutment surfaces 4 is in projecting from the plane of the other abutment surface 4 and is disposed, when the device is put in place, opposite the button 19 which is in the depressed position. Thus, regardless of the fact that the upper part 1 masks the push button 18, it cannot be operated because it would cause the button 19 to exit, which would then come into abutment against the corresponding abutment surface 4.

Bien entendu l'invention n'est pas limitée aux modes de réalisation décrits ci-dessus et on peut y apporter des variantes d'exécution.Of course, the invention is not limited to the embodiments described above and it is possible to make variant embodiments.

Par exemple, la partie 1 au lieu d'être réalisée en matière plastique peut être réalisée en un matériau rigide, tel que de l'acier ou un alliage léger, la charnière 2 étant alors réalisée par un axe engagé dans des manchons solidaires des parties 1. Les ouvertures 5 peuvent également être réalisées dans des ailes 6 rigidement reliées aux parties 1 transversalement à celles-ci.For example, part 1 instead of being made of plastic material can be made of a rigid material, such as steel or a light alloy, the hinge 2 then being produced by an axis engaged in sleeves integral with the parts 1. The openings 5 can also be produced in wings 6 rigidly connected to the parts 1 transversely to the latter.

Bien que le dispositif selon l'invention ait été représenté avec trois ouvertures 5, permettant d'introduire trois cadenas différents suivant les normes de sécurité en vigueur, on peut prévoir une seule ouverture associée à chaque partie 1 ou au contraire un plus grand nombre d'ouvertures.Although the device according to the invention has been shown with three openings 5, making it possible to introduce three different padlocks according to the safety standards in force, it is possible to provide a single opening associated with each part 1 or on the contrary a greater number of 'openings.

On comprend également aisément que le profil des surfaces de butée 4 peut être adapté à la forme de la commande manuelle de l'appareil électrique sur lequel le dispositif de verrouillage est monté.It is also easily understood that the profile of the abutment surfaces 4 can be adapted to the shape of the manual control of the electrical device on which the locking device is mounted.

De plus, bien que pour des raisons de symétrie de mouvement de la commande manuelle 14, la charnière 2 ait été représentée dans une position médiane du dispositif, on peut prévoir d'excentrer la charnière 2 ou de la remplacer par tout moyen équivalent permettant un mouvement des surfaces de butée 4 pour les écarter de la commande manuelle lorsque les ouvertures 5 ne sont pas maintenues en coincidence et au contraire maintenir celle-ci à proximité de la commande manuelle lorsque les ouvertures 5 sont mises en coincidence et maintenues dans cette position.In addition, although for reasons of symmetry of movement of the manual control 14, the hinge 2 has been shown in a central position of the device, provision may be made to offset the hinge 2 or to replace it by any equivalent means allowing a movement of the abutment surfaces 4 to move them away from the manual control when the openings 5 are not kept in coincidence and on the contrary keep the latter close to the manual control when the openings 5 are placed in coincidence and maintained in this position.
