Description

L'invention est relative à un dispositif de prolongement d'une manette basculante de commande d'un appareil électrique susceptible d'être fixé sur l'extrémité de la manette pour accroître sa hauteur.The invention relates to a device for extending a tilting joystick for controlling an electrical appliance capable of being fixed to the end of the joystick to increase its height.

Les manettes basculantes de manoeuvre des disjoncteurs miniatures sont relativement courtes, et il est assez difficile de les manoeuvrer. La présente invention concerne un prolongateur permettant de rendre plus aisée la préhension de la manette et accessoirement d'individualiser les disjoncteurs en permettant la fixation d'une étiquette sur le prolongateur.The tilting operating levers for miniature circuit breakers are relatively short, and it is quite difficult to operate them. The present invention relates to an extender making it easier to grip the handle and incidentally to individualize the circuit breakers by allowing the attachment of a label on the extender.

Le dispositif selon l'invention est caractérisé par le fait qu'il comporte une barrette de prolongement en matière plastique rigide ayant un profil en H dont la base est susceptible d'être engagée à chevauchement et clipsée sur ladite extrémité par flexion de l'âme de section réduite du profiléen H, et une clé de blocage susceptible d'être engagée dans la partie supérieure du profilé en H pour s'opposer à toute flexion de l'âme du profilé et verrouiller la barrette sur la manette.The device according to the invention is characterized in that it comprises an extension bar made of rigid plastic material having an H profile, the base of which is capable of being engaged overlapping and clipped onto said end by bending of the core of reduced section of the profile H, and a locking key capable of being engaged in the upper part of the profile in H to oppose any bending of the core of the profile and to lock the bar on the lever.

L'emploi d'un matériau rigide évite toute déformation sous l'effort de manoeuvre et la forme particulière de la barrette autorise une déformation ou l'encliquetage du prolongateur par l'avant, toute déformation étant par la suite empêchée par l'insertion de la clé de blocage. Le montage par l'avant permet un encliquetage sur une manette d'un disjoncteur équipé d'un bloc auxiliaire, notamment d'un bloc de protection différentiel dont le profil déborde et empêche un glissement du prolongateur par le côté sur la manette. La manette peut comporter d'origine des saillies ou nervures permettant le clipsage ou l'encliquetage de la barrette de prolongement, ou selon un mode de mise en oeuvre préféré, l'encliquetage s'effectue sur une barre d'accouplement des manettes des différents pôles d'un disjoncteur multipolaire, ladite barre constituant une surépaisseur ou un renflement à l'extrémité des manettes.The use of a rigid material avoids any deformation under the maneuvering force and the particular shape of the bar allows a deformation or the latching of the extension from the front, any deformation being subsequently prevented by the insertion of the locking key. Mounting from the front allows snapping onto a handle of a circuit breaker fitted with an auxiliary block, in particular a differential protection block, the profile of which protrudes and prevents sliding of the extension cable from the side on the handle. The lever may have original projections or ribs for clipping or snap-on of the extension bar, or according to a preferred embodiment, the snap-on is effected on a coupling bar of the handles of the different poles of a multipole circuit breaker, said bar constituting an additional thickness or a bulge at the end of the handles.

Un autre but de la présente invention est de permettre l'individualisation des disjoncteurs par la fixation d'une étiquette. Selon un développement de l'invention, l'étiquette est insérée dans 1-a partie supérieure de la barrette et est verrouillée ou maintenue par la clé de blocage insérée en position montée dans la partie supérieure du profilé. La clé de blocage est en un matériau transparent, et selon un développement de l'invention, elle est conformée en loupe facilitant la lecture de l'étiquette.Another object of the present invention is to allow the individualization of circuit breakers by attaching a label. According to a development of the invention, the label is inserted into 1-a upper part of the bar and is locked or held by the blocking key inserted in the mounted position in the upper part of the profile. The locking key is made of a transparent material, and according to a development of the invention, it is shaped like a magnifying glass facilitating the reading of the label.

La clé de blocage épouse en position montée le profil externe de la barrette, de manière à constituer un ensemble monobloc rigidement assujetti à la manette du disjoncteur. En position montée tout déplacement latéral du prolongateur est empêché par l'effort de serrage exercé sur la manette. Le dé--montage du prolongateur peut être effectué par enlèvement de la clé de blocage et par la suite par un pincement de la partie supérieure du profilé tendant à écarter les pattes enserrant la manette.The locking key matches the external profile of the bar in the mounted position, so as to constitute a one-piece assembly rigidly secured to the handle of the circuit breaker. In the mounted position, any lateral movement of the extension is prevented by the tightening force exerted on the lever. The extension can be removed by removing the locking key and subsequently by pinching the upper part of the profile tending to spread the tabs surrounding the handle.

D'autres avantages et caractéristiques ressortiront plus clairement de la description qui va suivre d'un mode de mise en oeuvre de l'invention; donné à titre d'exemple non limitatif et représenté au dessin annexé, dans lequel :

  • la figure 1 est une vue schématique en perspective de la manette et du prolongateur selon l'invention, représentés en position démontée;
  • la figure 2 est une vue de côté à échelle agrandie, représentant le prolongateur encliqueté sur la manette, la clé de blocage étant démontée;
  • la figure 3 est une vue en élévation de la clé de blocage;
  • la figure 4 est une vue en élévation et en coupe de la barrette;
  • la figure 5 est une vue en plan de la barrette.
Other advantages and characteristics will emerge more clearly from the description which follows of an embodiment of the invention; given by way of nonlimiting example and represented in the appended drawing, in which:
  • Figure 1 is a schematic perspective view of the handle and the extender according to the invention, shown in the disassembled position;
  • Figure 2 is a side view on an enlarged scale, showing the extension snapped onto the handle, the locking key being removed;
  • Figure 3 is an elevational view of the locking key;
  • Figure 4 is an elevational view in section of the bar;
  • Figure 5 is a plan view of the bar.

Sur les figures, un disjoncteur 10 bipolaire constitué par l'assemblage de deux pôles ayant chacun une manette 12, 14 de manoeuvre, présente une barre d'accouplement 16 en forme de U emboîtée sur les extrémités des manettes 12, 14 pour permettre une commande simultanée par basculement des manettes 12, 14 des pôles du disjoncteur 10. La barre d'accouplement 16 en fer U emboîtée sur les manettes 12, 14, constitue un renflement ou une surépaisseur en bordure des manettes 12, 14. Le dispositif de prolongement ou prolongateur, désigné par le repère général 18, comporte une barrette 20, constituée par un profilé de forme générale en H et une clé de blocage 22. Le profilé en H 20 présente à sa base deux pattes 24, 26 susceptibles de s'emboîter sur les manettes 12, 14 et la barre d'accouplement 16. Les pattes 24, 26 pré--sentent un écartement réduit à la base correspondant sensiblement à l'épaisseur des manettes 12, 14, mais inférieur à la partie renflée constituée par la barre d'accouplement 16 (voir fig. 2). La barrette 20 est en un matériau plastique rigide, par exemple en une résine polycarbonate renforcée, et l'âme ou pont de liaison 28 entre les deux branches du profilé en H est d'une épaisseur suffisamment faible pour conférer une certaine souplesse suffisante à un écartement des pattes 24, 26 pour l'encliquetage sur l'ensemble manettes 12, 14 - barre d'accouplement 16. La déformation de la barrette 20 peut être réalisée par pincement de sa partie supérieure tendant à rapprocher les deux branches et à fléchir l'âme 28 pour écarter les pattes inférieures 24, 26.In the figures, a bipolar circuit breaker 10 constituted by the assembly of two poles each having a lever 12, 14 for operating, has a U-shaped coupling bar 16 fitted on the ends of the levers 12, 14 to allow control simultaneous by tilting of the handles 12, 14 of the poles of the circuit breaker 10. The coupling bar 16 of iron U fitted on the handles 12, 14, constitutes a bulge or an additional thickness at the edge of the handles 12, 14. The extension device or extension, designated by the general reference 18, comprises a bar 20, constituted by a generally H-shaped profile and a locking key 22. The H-shaped profile 20 has at its base two tabs 24, 26 capable of fitting onto the levers 12, 14 and the coupling bar 16. The legs 24, 26 have a reduced spacing at the base corresponding substantially to the thickness of the levers 12, 14, but less than the bulged part formed by the bar mating 16 (see fig. 2). The bar 20 is made of a rigid plastic material, for example a reinforced polycarbonate resin, and the core or connecting bridge 28 between the two branches of the H-shaped section is of a thickness that is sufficiently small to confer a certain sufficient flexibility on a spacing of the tabs 24, 26 for snapping onto the lever assembly 12, 14 - coupling bar 16. The deformation of the bar 20 can be achieved by pinching its upper part tending to bring the two branches together and to bend the 'soul 28 to spread the lower legs 24, 26.

La barrette 20 est verrouillée en position montée sur les manettes 12, 14 par insertion entre les branches 32, 34 dela partie supérieure de la barrette 20, d'une clé de blocage 22 remplissant l'intervalle ménagé entre les branches 32, 34. La clé de blocagej en forme de plaquette d'une largeur correspondant à l'écartement des branches 32, 34 en position montée de la barrette 20, est maintenue en position montée par l'encliquetage de deux pattes d'extrémité 36, 38 à saillies 40 dans des décrochements 42 ménagés dans la face interne des branches 32, 34. La clé de blocage 22 est en un matériau rigide, par exemple identique à celui de la barrette 20 et l'élasticité nécessaire à l'encliquetage des pattes 36, 38 est conférée par une saignée 44, ménagée dans les pattes 36, 38. En position montée de la clé de blocage 22, la face supérieure de cette dernière affleure avec les extrémités des branches 32, 34 en obturant entièrement le dessus de la barrette 20. La clé de blocage 22 est en un matériau transparent et est conformée pour présenter une face supérieure convexe et une face inférieure concave de rayon plus grand que celui de la face supérieure, la combinaison des deux faces constituant ainsi une barrette à effet de loupe. Entre les branches 32, 34 du profilé 20 sont disposées deux nervures 46, 48, dont la face supérieure est légèrement en retrait de l'extrémité des branches 32, 34. Les nervures 46, 48 constituent un support d'une étiquette 50 en forme de plaquette posée sur les bords des nervures 46, 48 et coiffée par la clé de blocage 22 en position montée de cette dernière. Il est facile de voir que l'étiquette 50 est retenue par les deux arêtes intérieures de la clé de blocage 22, qui en facilite sa lecture par l'effet de loupe décrit ci-dessus. La longueur de l'étiquette 50 est inférieure à l'écartement des pattes 36, 38 entre lesquelles elle s'emboîte.The bar 20 is locked in the position mounted on the levers 12, 14 by insertion between the branches 32, 34 of the upper part of the bar 20, of a locking key 22 filling the gap between the branches 32, 34. The locking keyj in the form of a plate with a width corresponding to the spacing of the branches 32, 34 in the mounted position of the bar 20, is maintained in the mounted position by the snap-fastening of two end tabs 36, 38 with projections 40 in recesses 42 formed in the internal face of the branches 32, 34. The locking key 22 is made of a rigid material, for example identical to that of the bar 20 and the elasticity necessary for the latching of the legs 36, 38 is imparted by a groove 44, formed in the legs 36, 38 In the mounted position of the locking key 22, the upper face of the latter is flush with the ends of the branches 32, 34 by completely sealing off the top of the bar 20. The locking key 22 is made of a transparent material and is shaped to have a convex upper face and a concave lower face with a radius greater than that of the upper face, the combination of the two faces thus constituting a bar with magnifying glass effect. Between the branches 32, 34 of the profile 20 are arranged two ribs 46, 48, the upper face of which is slightly set back from the end of the branches 32, 34. The ribs 46, 48 constitute a support for a label 50 in the form plate placed on the edges of the ribs 46, 48 and capped by the locking key 22 in the mounted position of the latter. It is easy to see that the label 50 is retained by the two internal edges of the locking key 22, which makes it easier to read by the magnifying glass effect described above. The length of the label 50 is less than the spacing of the tabs 36, 38 between which it fits.

Le dispositif de prolongement selon l'invention est mis en oeuvre de la manière suivante :

  • Le prolongateur 20, 22 est livré comme pièce détachée, la longueur correspondant aux longueurs standard des barres d'accouplement 16. Pour la mise en place de la barrette 20 sur l'ensemhle manettes 12, 14 - barre d'accouplement 16, il suffit de pincer les branches supérieures 32, 34 et d'encliqueter la barrette sur la barre d'accouplement 16 et les manettes 12, 14, le montage étant facilité par la flexion de l'âme 28 de la barrette 20. Lorsque les faces latérales du disjoncteur 10 sont dégagées, la barrette 20 peut bien entendu être glissée par le côté sur l'ensemble manettes 12, 14 - barre d'accouplement 16, le coulissement étant éventuellement facilité par un pincement des branches supérieures 32, 34. La barrette 20 étant encliquetée, on pose l'étiquette 50 sur les supports 46, 48 et on encliquète la clé de blocage 22 entre les branches 32, 34 de la partie supérieure de la barrette 20. L'encliquetage est facilité par la saignée 44 permettant une déformation des pattes 36, 38. En position montée, la clé de blocage 22 verrouille la barrette 20 sur les manettes 12, 14 empêchant tout glissement latéral ou tout arrachement du prolongateur 20, 22, notamment lors d'une manoeuvre ou d'un déclenchement brutal du disjoncteur. La clé de blocage 22 est positionnée latéralement par les nervures 46, 48 engagées entre les pattes 36, 38. L'étiquette 50 peut être lue avec un agrandissement à travers la loupe constituée par la clé de blocage 22.
The extension device according to the invention is implemented in the following manner:
  • The extension 20, 22 is delivered as a spare part, the length corresponding to the standard lengths of the coupling bars 16. For the installation of the bar 20 on the set of levers 12, 14 - coupling bar 16, it suffices pinch the upper arms 32, 34 and snap the bar onto the coupling bar 16 and the levers 12, 14, the mounting being facilitated by the bending of the core 28 of the bar 20. When the lateral faces of the circuit breaker 10 are released, the bar 20 may well heard being slid from the side over the lever assembly 12, 14 - coupling bar 16, the sliding being possibly facilitated by pinching the upper branches 32, 34. The bar 20 being snapped on, the label 50 is placed on the supports 46, 48 and the locking key 22 is engaged between the arms 32, 34 of the upper part of the bar 20. The engagement is facilitated by the groove 44 allowing the legs 36, 38 to be deformed. In the mounted position, the locking key 22 locks the bar 20 on the levers 12, 14 preventing any lateral sliding or any tearing of the extender 20, 22, in particular during an operation or a sudden tripping of the circuit breaker. The locking key 22 is positioned laterally by the ribs 46, 48 engaged between the tabs 36, 38. The label 50 can be read with an enlargement through the magnifying glass formed by the locking key 22.

Le démontage s'effectue par une opération inverse d'enlèvement de la clé de blocage 22, notamment par insertion d'un ' outil pour serrer les pattes 36, 38. Après enlèvement de la clé de blocage 22 la barrette 20 peut être arrachée en pinçant les branches supérieures 32, 34. La hauteur de la barrette-.20 correspond bien entendu à la prolongation recherchée, et la longueur du prolongateur 20, 22 correspond à celle de la manette ou plus exactement de la barre d'accouplement 16 des manettes 12, 14. Il est clair que le prolongateur selon l'invention est utilisable sur des manettes dépourvues d'une barre d'accouplement, mais conformées pour présenter une extrémité renflée ou des évidements d'encliquetage des parties d'encliquetage 24, 26. de la barrette 20.The disassembly is carried out by a reverse operation of removing the locking key 22, in particular by inserting a ' tool for tightening the tabs 36, 38. After removing the locking key 22 the bar 20 can be torn off by pinching the upper branches 32, 34. The height of the bar-.20 corresponds of course to the desired extension, and the length of the extension 20, 22 corresponds to that of the lever or more exactly of the coupling bar 16 of the levers 12, 14. It is clear that the extender according to the invention can be used on levers without a coupling bar, but shaped to have a bulged end or latching recesses of the latching parts 24, 26. bar 20.

L'invention n'est bien entendu nullement limitée au mode de mise en oeuvre plus particulièrement décrit et représenté.The invention is of course in no way limited to the mode of implementation more particularly described and shown.
