Description

La présente invention se rapporte à un opercule de plombage pour l'occultation d'un objet, tel qu'un interrupteur, une cellule de lecture, un organe de commande, une connexion ou autre. Elle se rapporte aussi à un compteur comportant un tel opercule.The present invention relates to a sealing cover for the concealment of an object, such as a switch, a reading cell, a control member, a connection or the like. It also relates to a counter comprising such a cover.

D'une manière générale, les dispositifs de plombage sont utilisés pour assurer l'intégrité d'un produit, par exemple d'un appareil de mesure tel qu'un compteur d'électricité, qui est confié à un utilisateur éventuellement susceptible de chercher à le démonter pour le falsifier. Dans ce cas, il est courant de relier une vis et son support par un fil de plombage fermé par un plomb d'authentification qui est détruit par le démontage de la vis.In general, the sealing devices are used to ensure the integrity of a product, for example a measuring device such as an electricity meter, which is entrusted to a user who may possibly seek to disassemble it to falsify it. In this case, it is common to connect a screw and its support by a sealing lead closed by an authentication lead which is destroyed by dismantling the screw.

Or, certains compteurs sont programmables et leur programmation peut être effectuée par l'intermédiaire d'une cellule de lecture optique ou magnétique placée derrière une fenêtre située sur le capot du compteur. Elle est aussi possible par l'intermédiaire d'une connexion. Ainsi pour ces compteurs, il est nécessaire d'assurer l'intégrité des moyens de comptage, mais aussi de garantir que leur programmation n'a pas été modifiée ou falsifiée.However, some meters are programmable and their programming can be carried out by means of an optical or magnetic reading cell placed behind a window located on the cover of the meter. It is also possible via a connection. Thus for these counters, it is necessary to ensure the integrity of the counting means, but also to guarantee that their programming has not been modified or falsified.

La présente invention permet d'occulter l'accès aux moyens de programmation, cellule optique ou magnétique, ou autre d'un dispositif de comptage et d'une manière générale d'occulter l'accès à un objet, tel qu'un organe de commande, interrupteur, connexion ou autre, tout en permettant d'assurer l'intégrité de cette occultation par plombage.The present invention makes it possible to conceal access to the programming means, optical or magnetic cell, or other of a counting device and generally to conceal access to an object, such as a control, switch, connection or other, while ensuring the integrity of this occultation by sealing.

De manière plus précise, un opercule de plombage selon la présente invention comprend :

  • une base comportant une ouverture pour permettre l'accès audit objet à occulter,
  • une pièce d'obturation apte à coopérer avec la base de manière à obturer l'ouverture et comprenant des moyens de passage pour le passage d'un fil de plombage,
  • des moyens de fixation pour solidariser ladite pièce d'obturation à la base,
  • une pièce de fermeture comprenant des moyens de passage prévus pour coopérer avec les moyens de passage de la pièce d'obturation de manière telle qu'un fil de plombage introduit dans lesdits moyens de passage rend la pièce de fermeture solidaire de la pièce d'obturation.
More specifically, a sealing seal according to the present invention comprises:
  • a base comprising an opening to allow access to said object to be obscured,
  • a closure piece able to cooperate with the base so as to close the opening and comprising passage means for the passage of a sealing wire,
  • fixing means for securing said closure piece to the base,
  • a closure piece comprising passage means provided for cooperating with the passage means of the closure piece so that a sealing wire introduced into said passage means makes the closure piece integral with the closure piece .

Selon une réalisation particulière, les moyens de passage de la pièce d'obturation comportent un téton traversé par un passage et comprenant une fente coupant le passage.According to a particular embodiment, the means of passage of the closure part comprise a stud crossed by a passage and comprising a slot cutting the passage.

Dans ce cas, les moyens de passage de la pièce de fermeture comportent un évidement apte à recevoir le téton et dans cet évidement une saillie présentant une encoche ladite saillie étant apte à pénétrer la fente du téton.In this case, the means for passing the closing part comprise a recess capable of receiving the stud and in this recess a projection having a notch, said projection being able to penetrate the slot of the stud.

Avantageusement, la pièce de fermeture comporte une fente de guidage incorporant l'encoche de la saillie.Advantageously, the closure part comprises a guide slot incorporating the notch of the projection.

Pour la préhension de la pièce de fermeture, celle-ci peut comporter deux évidements latéraux.For gripping the closure part, it may include two lateral recesses.

Selon un mode de réalisation particulier, les moyens de fixation comportent :

  • ménagé dans la base, au moins un trou débouchant,
  • supporté par la pièce d'obturation, au moins un pion épaulé apte à pénétrer dans ledit au moins un trou débouchant,
  • des moyens de verrouillage pour interdire la séparation de ladite pièce d'obturation d'avec la base lorsque celles-ci sont fixées l'une à l'autre.
According to a particular embodiment, the fixing means comprise:
  • formed in the base, at least one through hole,
  • supported by the closure part, at least one shoulder pin capable of penetrating said at least one through hole,
  • locking means for preventing the separation of said closure piece from the base when these are fixed to each other.

De manière préférée, chaque trou débouchant de la base est prolongé par un ajour présentant une largeur inférieure à la plus grande largeur du trou et à l'extension de l'épaulement du pion épaulé.Preferably, each hole emerging from the base is extended by an aperture having a width less than the largest width of the hole and the extension of the shoulder of the shouldered pin.

Avantageusement, deux trous débouchants sont prévus dans la base de part et d'autre de l'ouverture.Advantageously, two through holes are provided in the base on either side of the opening.

Préférentiellement, les moyens de verrouillage comportent :

  • au moins un trou débouchant percé dans la pièce d'obturation et positionné en vis-à-vis d'un trou débouchant de la base lorsque la pièce d'obturation coopère avec la base,
  • au moins une patte fixée sur la pièce de fermeture prévue pour traverser un trou débouchant de la pièce d'obturation et pénétrer un trou débouchant de la base et possédant une extension supérieure à la largeur de l'ajour.
Preferably, the locking means comprise:
  • at least one through hole drilled in the closure piece and positioned opposite a hole opening from the base when the closure piece cooperates with the base,
  • at least one tab fixed on the closure part provided for passing through a hole opening out from the closure part and penetrating a hole opening out from the base and having an extension greater than the width of the aperture.

En variante, la base peut être en métal.Alternatively, the base can be made of metal.

L'invention concerne aussi un compteur comportant un tel opercule.The invention also relates to a counter comprising such a cover.

D'autres caractéristiques et avantages de l'invention ressortiront clairement de la description qui en est faite ci-après, à titre indicatif et nullement limitatif, en référence au dessin annexée, sur lequel :

  • la figure 1 représente schématiquement une vue perspective de dessous en éclaté d'un opercule de plombage conforme à l'invention ;
  • la figure 2 représente schématiquement une vue perspective de dessus en éclaté de l'opercule de plombage de la figure 1 ;
  • la figure 3 représente schématiquement une vue perspective de dessous de l'opercule de la figure 1 assemblé ;
  • la figure 4, composée de la figure 4a et de la figure 4b représente schématiquement deux coupes perpendiculaires de l'opercule de la figure 1.
Other characteristics and advantages of the invention will emerge clearly from the description which is given below, for information and in no way limitative, with reference to the appended drawing, in which:
  • Figure 1 schematically shows a perspective exploded view from below of a sealing seal according to the invention;
  • FIG. 2 schematically represents an exploded perspective view from above of the sealing seal of FIG. 1;
  • Figure 3 schematically shows a perspective view from below of the cover of Figure 1 assembled;
  • FIG. 4, composed of FIG. 4a and of FIG. 4b, schematically represents two perpendicular sections of the cover of FIG. 1.

La figure 1 représente schématiquement une vue de dessous en éclaté d'un opercule de plombage 1 conforme à l'invention. Sur cette figure et les suivantes, l'opercule présente un contour circulaire mais peut prendre d'autres contours, carré ou rectangulaire ou autre, selon l'environnement sur lequel il doit s'adapter.Figure 1 schematically shows an exploded bottom view of a sealing seal 1 according to the invention. In this figure and the following ones, the cover presents a circular outline but can take other contours, square or rectangular or other, according to the environment on which it must adapt.

L'opercule 1 est constitué d'une base 10, une pièce d'obturation 20, et d'une pièce de fermeture 30.The cover 1 consists of a base 10, a closing piece 20, and a closing piece 30.

La base 10 est prévue pour être fixée sur l'élément qui comprend ou protège l'objet à occulter. Ainsi dans l'exemple de réalisation représenté et bien adapté à l'occultation d'une cellule optique de lecture/écriture pour la lecture des données issues d'un compteur et la programmation de ce dernier, deux ouvertures 11, 12 sont prévues pour permettre la fixation de la base 10 sur la fenêtre de la cellule (non représentée) à l'aide de vis ou par emboutissage sur des picots prévus à cet effet sur la fenêtre.The base 10 is intended to be fixed to the element which comprises or protects the object to be obscured. Thus in the embodiment shown and well suited to the concealment of an optical read / write cell for reading data from a counter and programming the latter, two openings 11, 12 are provided to allow fixing the base 10 on the cell window (not shown) using screws or by stamping on pins provided for this purpose on the window.

En variante, la base 10 peut être moulée directement avec la fenêtre plutôt que de prévoir une pièce rapportée.Alternatively, the base 10 can be molded directly with the window rather than providing an insert.

Malgré tout, faire appel à une pièce rapportée permet de fabriquer celle-ci en métal. Ceci est particulièrement avantageux dans une application d'obturation d'une cellule d'écriture/lecture de compteur car la base 10 sert alors à la fixation par aimantation de la tête de lecture/écriture utilisée pour lire les données délivrées par le compteur et/ou la programmation de celui-ci, étant entendu que le boîtier du compteur est normalement réalisé en matière plastique.In spite of everything, using an insert makes it possible to make it out of metal. This is particularly advantageous in an application for closing a meter read / write cell since the base 10 is then used for fixing by magnetization the read / write head used to read the data delivered by the meter and / or programming it, it being understood that the meter housing is normally made of plastic.

Dans l'exemple de réalisation représenté, la base 10 est donc une plaque circulaire mince percée d'une ouverture principale 13 destinée à permettre l'accès à l'objet (non représenté) occulté par l'opercule 1 quand celui-ci est en place.In the embodiment shown, the base 10 is therefore a thin circular plate pierced with a main opening 13 intended to allow access to the object (not shown) obscured by the cover 1 when the latter is in square.

La base 10 comprend encore de part et d'autre de l'ouverture 13, deux trous débouchants 14, 15 prolongés chacun par deux ajours 16a, 16b et 17a, 17b.The base 10 also comprises on either side of the opening 13, two through holes 14, 15 each extended by two openings 16a, 16b and 17a, 17b.

La pièce d'obturation 20 est destinée à coopérer avec la base 10. Elle comporte une face inférieure 21 et une face supérieure visible sur la figure 2.The closure piece 20 is intended to cooperate with the base 10. It has a lower face 21 and an upper face visible in FIG. 2.

La face inférieure 21 supporte deux pions épaulés 26, 27 disposés de manière à pouvoir être introduits simultanément dans les trous débouchants 14, 15 de la base 10, puis par une rotation de la pièce d'obturation 20, à glisser le long des ajours 16a, 17b respectivement ou 16b, 17a respectivement selon que la rotation est horaire ou antihoraire.The lower face 21 supports two shoulder pins 26, 27 arranged so that they can be introduced simultaneously into the through holes 14, 15 of the base 10, then by a rotation of the closure piece 20, to slide along the openings 16a , 17b respectively or 16b, 17a respectively depending on whether the rotation is clockwise or counterclockwise.

La pièce d'obturation 20 est percée de deux trous débouchants 24, 25 disposés de manière telle que, lorsque les pions 26, 27 sont en place dans les ajours 16a, 17b ou de manière équivalente 16b, 17a, les trous 24, 25 sont en vis-à-vis des trous débouchants 14, 15 respectivement percés dans la base 10.The sealing piece 20 is pierced with two through holes 24, 25 arranged in such a way that, when the pins 26, 27 are in place in the openings 16a, 17b or in an equivalent manner 16b, 17a, the holes 24, 25 are opposite the through holes 14, 15 respectively drilled in the base 10.

La figure 2 représente une vue perspective de dessus en éclaté de l'opercule 1.FIG. 2 represents an exploded perspective view from above of the cover 1.

La face supérieure 22 de la pièce d'obturation 20 supporte un téton 23 traversé de part en part par un passage 28 et comprenant une fente 29 coupant ledit passage 28 à angle droit. Le passage 28 est destiné à recevoir le fil de plombage comme cela sera détaillé plus loin.The upper face 22 of the closure piece 20 supports a stud 23 traversed right through by a passage 28 and comprising a slot 29 cutting said passage 28 at right angles. The passage 28 is intended to receive the sealing wire as will be detailed below.

De retour à la figure 1, on voit que la pièce de fermeture 30 possède deux pattes 34, 35 prévues pour traverser les trous débouchants 24, 25 de la pièce d'obturation et pénétrer les trous 14, 15 de la base 10. Toutefois, l'extension ou la largeur de ces pattes 34, 35 est supérieure à la largeur des ajours 16a, 16b, 17a, 17b. De cette manière, les pattes 34, 35 ne peuvent pas pénétrer les ajours 16a,16b,17a,17b.Returning to FIG. 1, it can be seen that the closure part 30 has two tabs 34, 35 provided for passing through the through holes 24, 25 of the closure part and penetrating the holes 14, 15 of the base 10. However, the extension or the width of these legs 34, 35 is greater than the width of the openings 16a, 16b, 17a, 17b. In this way, the tabs 34, 35 cannot penetrate the openings 16a, 16b, 17a, 17b.

La pièce de fermeture 30 possède un évidement 33 apte à recevoir le téton 23 de la pièce d'obturation. Une saillie 39 présentant une encoche 38 est disposée dans l'évidement 33 de manière à pénétrer la fente 29 du téton 23 lorsque les pièces 20 et 30 sont emboîtées. Dans ce cas, l'encoche 38 se trouve dans la continuité du passage 28.The closing piece 30 has a recess 33 able to receive the stud 23 of the sealing piece. A projection 39 having a notch 38 is disposed in the recess 33 so as to penetrate the slot 29 of the stud 23 when the parts 20 and 30 are fitted. In this case, the notch 38 is in the continuity of the passage 28.

On peut voir sur la figure 2 que la face supérieure 32 de la pièce de fermeture 30 comprend une fente de guidage 37 incorporant l'encoche 38. La fente de guidage 37 facilite l'introduction du fil de plombage, lorsque les différents éléments 10, 20, 30 sont emboîtés. De part et d'autre de la fente 37, deux évidements latéraux 40a, 40b facilitent la préhension de la pièce de fermeture 30.It can be seen in FIG. 2 that the upper face 32 of the closure part 30 comprises a guide slot 37 incorporating the notch 38. The guide slot 37 facilitates the introduction of the sealing wire, when the various elements 10, 20, 30 are nested. On either side of the slot 37, two lateral recesses 40a, 40b facilitate gripping of the closing part 30.

La figure 3 représente schématiquement une vue perspective de dessous de l'opercule assemblé. La base 10 est pourvue d'ouverture 11, 12 pour sa fixation autour de l'objet à occulter. Par cette fixation la base 10 est normalement inamovible.FIG. 3 schematically represents a perspective view from below of the assembled cover. The base 10 is provided with opening 11, 12 for its fixing around the object to be obscured. By this fixing the base 10 is normally irremovable.

Pour assurer l'obturation de l'ouverture 13 et le plombage de l'opercule, la pièce d'obturation 20 est d'abord rendue solidaire de la base 10 grâce à des moyens de fixation prévus à cet effet. Dans l'exemple de réalisation représenté, ces moyens de fixation sont constitués d'une part par les trous débouchants 14, 15 et les ajours 16a, 17b ou de manière équivalente 16b, 17a, par les pions épaulés 26, 27 et par des moyens de verrouillage constitués ici par les pattes 34, 35 et les trous débouchants 24, 25.To seal the opening 13 and seal the seal, the sealing piece 20 is first made integral with the base 10 by means of fixing provided for this purpose. In the example of embodiment shown, these fixing means consist on the one hand of through holes 14, 15 and the openings 16a, 17b or in an equivalent manner 16b, 17a, by the shouldered pins 26, 27 and by means locking here constituted by the legs 34, 35 and the through holes 24, 25.

Pour solidariser la pièce d'obturation 20 à la base 10, on fait d'abord pénétrer les pions 26, 27 dans les trous débouchants 14, 15 respectivement. Puis par un mouvement de rotation, on fait ensuite translater les pions 26, 27 dans les ajours 16a, 17b respectivement. Les ajours possédant une largeur inférieure à l'extension de l'épaulement des pions, le mouvement de retrait vertical est alors interdit pour la pièce d'obturation 20. Dans cette position, les trous débouchants 24, 25 dont est pourvue la pièce d'obturation 20 se retrouvent en vis-à-vis des trous débouchants 14, 15 respectivement de la base 10.To secure the closure piece 20 to the base 10, the pins 26, 27 are first penetrated into the through holes 14, 15 respectively. Then by a rotational movement, the pins 26, 27 are then translated into the openings 16a, 17b respectively. The openings having a width less than the extension of the shoulder of the pins, the vertical withdrawal movement is then prohibited for the closure piece 20. In this position, the through holes 24, 25 which are provided with the piece of obturation 20 are found opposite the through holes 14, 15 respectively of the base 10.

Pour immobiliser la pièce d'obturation 20 dans cette position, il suffit de faire appel aux moyens de verrouillage. On fait pénétrer les pattes 34, 35 à travers les trous débouchants 24, 25 de la pièce d'obturation 20 puis dans les trous débouchants 14, 15 de la base 10. L'extension ou largeur des pattes 34, 35 étant supérieure à la largeur des ajours 16a, 16b, 17a, 17b, les pattes 34, 35 ne peuvent translater dans les ajours et la pièce de fermeture est donc bloquée en rotation, entraînant le blocage de la pièce d'obturation 20 dans sa position.To immobilize the closure piece 20 in this position, it suffices to use the locking means. The legs 34, 35 are made to penetrate through the through holes 24, 25 of the closure piece 20 then into the through holes 14, 15 of the base 10. The extension or width of the legs 34, 35 being greater than the width of the openings 16a, 16b, 17a, 17b, the lugs 34, 35 cannot translate into the openings and the closure part is therefore locked in rotation, causing the blocking piece 20 to lock in its position.

Le fil de plombage est alors utilisé pour solidariser la pièce de fermeture 30 à la pièce d'obturation 20, comme on va le voir notamment en référence à la figure 4.The sealing wire is then used to secure the closure part 30 to the closure part 20, as will be seen in particular with reference to FIG. 4.

La figure 4 est composée d'une figure 4a et d'une figure 4b représentant deux coupes perpendiculaires de l'opercule assemblé. La figure 4a est une coupe de l'opercule selon un axe s'étendant selon la fente 29 de la pièce d'obturation 20. La figure 4b est une coupe de l'opercule selon un axe s'étendant selon la fente de guidage 37 de la pièce de fermeture 30. Dans l'exemple de réalisation représenté, lorsque les différents éléments sont emboîtés, ces deux axes sont perpendiculaires, mais on comprend qu'il pourrait en être autrement.Figure 4 is composed of a Figure 4a and a Figure 4b showing two perpendicular sections of the assembled cover. Figure 4a is a section of the cover along an axis extending along the slot 29 of the closure member 20. Figure 4b is a section of the cover along an axis extending along the guide slot 37 of the closing part 30. In the embodiment shown, when the different elements are fitted, these two axes are perpendicular, but it is understood that it could be otherwise.

Lorsque les pièces d'obturation 20 et de fermeture 30 sont emboîtées, le téton 23 est introduit dans l'évidement 33 et la saillie 39 pénètre la fente 29. Dans cette configuration, le téton 23 de la pièce d'obturation, et l'encoche 38 pratiquée dans la saillie 39 forment globalement un passage pour un fil de plombage 50. Ce dernier est introduit dans la fente de guidage 29 qui le guide vers le passage 28 à l'intérieur duquel il traverse l'encoche 38 pour ressortir à l'autre extrémité du passage 28. De cette manière la pièce de fermeture 30 est solidaire de la pièce d'obturation. En effet, le retrait vertical de la pièce de fermeture 30 est interdit grâce au blocage du fond de la saillie 39a par le fil de plombage 50, lui-même immobilisé par les parois supérieures 23a du passage 28.When the shutter 20 and closure 30 pieces are fitted, the stud 23 is introduced into the recess 33 and the projection 39 penetrates the slot 29. In this configuration, the stud 23 of the shutter piece, and the notch 38 formed in the projection 39 generally form a passage for a sealing wire 50. The latter is introduced into the guide slot 29 which guides it towards the passage 28 inside which it passes through the notch 38 to exit the 'other end of the passage 28. In this way the closure part 30 is integral with the closure part. In fact, the vertical withdrawal of the closing part 30 is prohibited by blocking the bottom of the projection 39a by the sealing wire 50, itself immobilized by the upper walls 23a of the passage 28.

Le fil de plombage 50, une fois ses extrémités reliées par un plomb d'authentification (non représenté), ne peut être retiré du passage 28 : l'intégrité de l'obturation de l'ouverture 13 est donc ainsi garantie.The sealing wire 50, once its ends connected by an authentication lead (not shown), cannot be removed from the passage 28: the integrity of the closure of the opening 13 is thus guaranteed.

En effet, une fois le dispositif en place et fermé par un plomb, le seul moyen d'accéder à l'ouverture 13 est de briser soit le fil de plombage soit le plomb. Le dispositif décrit précédemment peut aussi être réalisé selon des variantes tout en restant dans le cadre de la présente invention.Indeed, once the device in place and closed with a lead, the only way to access the opening 13 is to break either the sealing wire or the lead. The device described above can also be produced according to variants while remaining within the scope of the present invention.

Par exemple, il peut être prévu un trou débouchant unique associé à un ajour sur la base, et donc corrélativement qu'un pion épaulé unique supporté par la pièce d'obturation apte à pénétrer le trou et à glisser dans l'ajour, tandis qu'une patte unique supportée par la pièce de fermeture vient bloquer verticalement l'ensemble formant l'opercule.For example, a single through hole may be provided associated with an aperture on the base, and therefore correlatively that a single shouldered pin supported by the closure piece capable of penetrating the hole and sliding in the aperture, while 'a single tab supported by the closure piece vertically blocks the assembly forming the cover.

D'autre part, il peut aussi être prévu plus de deux trous débouchants sur la base coopérant avec un nombre de pions et de pattes égal.On the other hand, it can also be provided more than two through holes on the base cooperating with an equal number of pins and legs.

Selon une autre variante, les trous débouchants prévus sur la base ne sont pas associés à un ajour, le ou les trous pouvant prendre par exemple une forme rectangulaire. Dans ce cas, le ou les pions épaulés doivent être prévus rectangulaires et aptes à pivoter sur eux-mêmes dans un mouvement de rotation d'un quart de tour. On fait pénétrer chaque pion dans son trou respectif puis on imprime au pion le mouvement de rotation qui bloque l'épaulement c'est-à-dire la longueur du pion contre les bords du trou. Une fois la pièce de fermeture en place, il n'est plus possible d'accéder au pions afin de les dégager. La pièce d'obturation est donc bien solidarisée à la base.According to another variant, the through holes provided on the base are not associated with an aperture, the hole or holes possibly taking, for example, a rectangular shape. In this case, the shoulder piece (s) must be rectangular and able to pivot on themselves in a quarter-turn rotational movement. Each pawn is made to penetrate into its respective hole, then the pawn is given the rotational movement which blocks the shoulder, that is to say the length of the pawn against the edges of the hole. Once the closing part in place, it is no longer possible to access the pins to release them. The closure piece is therefore securely attached to the base.

Les appareils de mesure comme les compteurs peuvent avantageusement comporter un opercule tel que décrit précédemment, par exemple pour assurer l'intégrité de l'occultation d'une fenêtre d'accès à un dispositif de lecture/écriture du compteur. Ce dispositif de lecture/écriture permettant d'une part le relevé du compteur mais aussi sa programmation, notamment en ce qui concerne les tarifs applicables, il est particulièrement intéressant de pouvoir plomber son accès afin de pouvoir mettre à jour, simplement et de manière économique, les fraudes ou tentatives de fraude.Measuring devices such as meters can advantageously include a cover as described above, for example to ensure the integrity of the concealment of an access window to a meter read / write device. This reading / writing device allowing on the one hand the reading of the meter but also its programming, in particular with regard to the applicable tariffs, it is particularly advantageous to be able to seal its access in order to be able to update, simply and economically , fraud or attempted fraud.
