Description
La présente invention concerne un appareil électrique comprenant un boîtier présentant sur une face frontale une manette de commande manuelle mobile entre deux positions extrêmes "marche" et "arrêt" et dotée de deux indications normalisées de position visibles une à une par l'utilisateur, l'une affectée à la position "marche" et dénommée ci-après indication "I", ayant la forme d'un tiret vertical et l'autre affectée à la position "arrêt" et dénommée ci-après indication "0", la forme d'un rond. Un appareil de ce type est déjà connu, comme par example du document GB.A. 495 577The present invention relates to an electrical appliance comprising a box having on a front face a manual control lever movable between two extreme positions "on" and "off" and provided with two standardized position indications visible one by one by the user, l 'one assigned to the "on" position and hereinafter referred to as indication "I", having the form of a vertical dash and the other assigned to the "off" position and hereinafter referred to as indication "0", the form of a round. An apparatus of this type is already known, such as for example from the document GB.A. 495,577
Pour ce type d'appareil électrique à manette de commande manuelle portant les indications "I" et "0", tel que par exemple un disjoncteur modulaire sous boîtier moulé, il est connu de réaliser par moulage la manette sous la forme d'un bouton qui est monté pivotant sur un axe fixe par rapport au boîtier de disjoncteur et qui est pourvu d'une saillie de préhension de part et d'autre de laquelle sont situées les deux indications ; par pivotement, le bouton passe de la position "marche" (fermeture du disjoncteur) dans laquelle seule apparaît l'indication "I", à la position "arrêt" (ouverture du disjoncteur) dans laquelle seule apparaît l'indication "0", et vice versa.For this type of electrical device with manual control handle bearing the indications "I" and "0", such as for example a modular circuit breaker in a molded case, it is known practice to mold the handle in the form of a button which is pivotally mounted on a fixed axis relative to the circuit breaker housing and which is provided with a gripping projection on either side of which the two indications are located; by pivoting, the button switches from the "on" position (closing of the circuit breaker) in which only the indication "I" appears, to the "off" position (opening of the circuit breaker) in which only the indication "0" appears, and vice versa.
On connaît déjà divers procédés permettant de réaliser les indications "I" et "0" portées par la manette de commande manuelle d'un appareil électrique, notamment un disjoncteur sous boîtier moulé. L'un consiste en un marquage par tampographie des deux symboles de part et d'autre de la prise manuelle de la manette. Ce procédé est toutefois long à exécuter, est coûteux et entraîne toujours des rebuts ; de plus, une erreur d'inversion des deux marques sur la manette est toujours possible ; également, les deux marques peuvent être effacées.Various methods are already known for making the indications "I" and "0" carried by the manual control lever of an electrical device, in particular a circuit breaker in a molded case. One consists of a padlock marking of the two symbols on either side of the manual grip of the joystick. This process is however long to execute, is expensive and always involves waste; in addition, an inversion error of the two marks on the controller is always possible; also, the two marks can be deleted.
Un autre procédé connu consiste à réaliser par un double moulage la manette avec deux saillies figurant les deux symboles considérés ; cependant, ce moulage a une durée de cycle relativement longue et est d'un coût élevé.Another known method consists in making the handle by double molding with two projections representing the two symbols considered; however, this molding has a relatively long cycle time and is of high cost.
La présente invention a pour but de remédier à tous ces inconvénients et de réaliser d'une manière simple et peu onéreuse les deux indications normalisées "I" et "0" de la manette de commande manuelle d'un appareil électrique, en les rendant indélébiles et apparentes sur l'appareil.The object of the present invention is to remedy all these drawbacks and to carry out in a simple and inexpensive manner the two standardized indications "I" and "0" of the manual control lever of an electrical appliance, by making them indelible. and visible on the device.
A cet effet, selon l'invention, un appareil électrique comprenant un boîtier présentant une face frontale munie d'une manette de commande manuelle susceptible d'être déplacée entre deux positions extrêmes "marche" et "arrêt", la manette s'étendant en recouvrement sur un élément support fixe par rapport au boîtier et portant sur sa face avant deux indications de position dont l'une est un tiret vertical indiquant la position "marche" et l'autre est un rond indiquant la position "arrêt", les deux indications étant placées l'une par rapport à l'autre de manière qu'une seule d'entre elles apparaisse après déplacement de la manette d'une position à l'autre, est caractérisé en ce que la manette et l'élément support sont de couleurs contrastantes, et que la manette est percée de deux ouvertures à travers chacune desquelles apparaît l'élément support sous-jacent et qui ressortent chacune sur l'élément support par contraste desdites couleurs, l'une des ouvertures étant rectiligne et constituant l'indication de la position "marche", l'autre ouverture étant circulaire et constituant l'indication de la position "arrêt".To this end, according to the invention, an electrical appliance comprising a housing having a front face provided with a manual control handle capable of being moved between two extreme "on" and "off" positions, the handle extending in covering on a support element fixed relative to the housing and carrying on its front face two position indications, one of which is a vertical dash indicating the "on" position and the other is a circle indicating the "off" position, both indications being placed in relation to each other so that only one of them appears after moving the handle from one position to another, is characterized in that the handle and the support element are of contrasting colors, and that the handle is pierced with two openings through each of which appears the underlying support element and which each emerge on the support element by contrast of said colors, one of the openings being rectilinear and constituting the indication of the "on" position, the other opening being circular and constituting the indication of the "off" position.
De préférence, les deux ouvertures rectiligne et circulaire ménagées dans la manette viennent de moulage avec cette dernière. Grâce à cette réalisation particulièrement simple des deux indications "I" et "0" de la manette, il en résulte avantageusement une réduction significative du coût global de fabrication de l'appareil électrique.Preferably, the two rectilinear and circular openings formed in the handle come from molding with the latter. Thanks to this particularly simple embodiment of the two indications "I" and "0" of the lever, this advantageously results in a significant reduction in the overall cost of manufacturing the electrical appliance.

Sur les figures 1 et 2, un boîtier moulé 10 électriquement isolant d'un appareil électrique tel que par exemple un disjoncteur, présente sur une face frontale 11 une lumière 13 de débattement d'une manette 15 de commande manuelle du disjoncteur.In FIGS. 1 and 2, a molded
La manette 15 est réalisée sous forme de bouton pivotant d'axe A₁ susceptible d'occuper deux positions extrêmes de pivotement, à savoir une position "marche", figure 1, correspondant à la fermeture du disjoncteur et une position symétrique "arrêt", figure 2, correspondant à l'ouverture du disjoncteur. La manette est sollicitée de façon classique en direction de l'une ou l'autre de ses deux positions par un ressort de rappel (non figuré).The
A l'exception de la manette de commande manuelle, on n'a pas représenté sur les figures 1 et 2 les autres organes qui constituent le mécanisme du disjoncteur car ils ne font pas partie de l'invention, celle-ci s'appliquant par ailleurs à tout autre type d'appareil électrique muni d'une manette de commande manuelle.With the exception of the manual control lever, the other members which constitute the mechanism of the circuit breaker have not been shown in FIGS. 1 and 2 since they are not part of the invention, the latter applying by elsewhere to any other type of electrical appliance fitted with a manual control lever.
Comme le montrent les figures 1 et 2, la manette 15 présente sur sa partie supérieure semi-cylindrique 17 une prise manuelle 18 accessible de l'extérieur du boîtier et susceptible de venir en butée sur la face avant il du boîtier de part et d'autre de la lumière 13 selon les positions "marche" et "arrêt" de la manette.As shown in FIGS. 1 and 2, the
La manette 15 pourvue de sa prise 18 est réalisée d'une seule pièce par moulage d'une matière isolante et est généralement d'une couleur différente de celle du boîtier 10.The
Dans un mode d'exécution, le boîtier 10 est formé de deux coquilles moulées d'importances inégales qui sont convenablement appliquées l'une contre l'autre et assemblées l'une avec l'autre au moyen de tout système de fixation approprié ; sur les figures 4 et 6, seule est visible la face frontale de l'une des coquilles, désignée par le repère général 21, l'autre coquille étant supposée enlevée.In one embodiment, the
Comme il apparaît sur les figures 4 et 6, la coquille 21 du boîtier présente tranversalement en saillie sur sa face latérale un axe tubulaire fixe 23 servant de support à la manette 15, cet axe s'étendant au milieu de la lumière 13 ménagée dans la face frontale 11 et recevant en engagement l'axe A₁ porté par la manette 15 ; lors de cet engagement, la partie semi-cylindrique 17 de la manette vient s'appliquer sur l'axe 23.As it appears in FIGS. 4 and 6, the
Il est à noter que l'axe de support 23 vient de moulage avec la coquille 21 du boîtier et est de même couleur que celle-ci.It should be noted that the
De manière connue en soi, la manette porte deux symboles ou repères normalisés servant à indiquer les positions "marche" et "arrêt" qu'elle peut occuper : comme le montre la figure 3, l'un des symboles a la forme d'un tiret vertical (indication "I") identifiant la position "marche", tandis que l'autre symbole a la forme d'un rond (indication "0") identifiant la position "arrêt". Les deux indications "I" et "0", figure 3, sont agencées en alignement de part et d'autre de la prise 18 de la manette, de manière à apparaître une à une lorsque la manette passe d'une position à l'autre.In a manner known per se, the joystick carries two standard symbols or marks used to indicate the "on" and "off" positions which it can occupy: as shown in FIG. 3, one of the symbols has the form of a vertical dash (indication "I") identifying the "on" position, while the other symbol has the shape of a circle (indication "0") identifying the "off" position. The two indications "I" and "0", FIG. 3, are arranged in alignment on either side of the
Suivant l'invention, comme le montrent les figures 4 et 6, les deux indications "I" et "0" sont constituées par deux ouvertures respectivement rectiligne 26 (figure 4) et circulaire 27 (figure 6) ménagées dans la partie 17 de la manette 15 et à travers chacune desquelles apparaît l'axe sous-jacent 23 supportant la manette ; en choisissant pour la manette 15 et l'axe 23 des couleurs respectives qui contrastent l'une avec l'autre, les ouvertures rectiligne 26 et circulaire 27 ressortent une à sur l'axe 23 par contraste des couleurs, indiquant ainsi de façon très visible à l'utilisateur la position "marche" ou "arrêt" qu'occupe la manette.According to the invention, as shown in Figures 4 and 6, the two indications "I" and "0" consist of two respectively rectilinear 26 (Figure 4) and circular 27 (Figure 6) openings formed in
A titre d'exemple non limitatif, la manette 15 est de couleur grise, tandis que l'axe support 23, c'est-à-dire en fait le boîtier dont il vient de moulage, est de couleur noire.By way of nonlimiting example, the
Avantageusement, les deux ouvertures rectiligne 26 et circulaire 27 viennent directement de moulage avec la manette 15 ; elles peuvent également être réalisées par des découpes dans la manette.Advantageously, the two rectilinear 26 and circular 27 openings come directly from molding with the
Il est à noter que l'axe 23 de support de la manette présente un diamètre tel que toute la partie semi-cylindrique 17 de la manette 15 repose sur cet axe 23, de sorte que chacune des deux ouvertures 26, 27 se détache toute entière par rapport à l'axe 23.It should be noted that the
Sur la figure 5, on a illustré le boîtier moulé 10 muni de la manette 15 occupant la position "marche" dans laquelle l'ouverture rectiligne 26 est visible par contraste des couleur, l'ouverture circulaire étant cachée par la face frontale du boîtier. De façon similaire, la figure 7 montre la manette 15 dans sa position "arrêt" repérée par l'ouverture circulaire 27 qui ressort par contraste, l'ouverture rectiligne étant cachée par la face frontale du boîtier 10.In Figure 5, there is illustrated the
Ainsi, dans le cas d'une manette montée pivotante sur un axe prévu dans le boîtier, l'invention utilise à profit cet axe comme fond sur lequel se détache chaque ouverture pratiquée dans la manette.Thus, in the case of a handle pivotally mounted on an axis provided in the housing, the invention makes use of this axis as a bottom on which detaches each opening made in the handle.
Bien entendu, l'invention s'applique également à une manette réalisée sous forme de poussoir ou coulisseau mobile en translation entre les deux positions extrêmes "marche" et "arrêt" ; dans ce cas, il est prévu dans le boîtier un support plat fixe, de couleur contrastant avec celle de la manette, sur lequel s'étend en recouvrement la manette percée des deux ouvertures rectiligne et circulaire, de manière à obtenir l'effet de contraste recherché.Of course, the invention also applies to a lever produced in the form of a push button or slide movable in translation between the two extreme positions "on" and "off"; in this case, there is provided in the housing a fixed flat support, in a color contrasting with that of the handle, on which extends in overlap the handle pierced with two rectilinear and circular openings, so as to obtain the effect of contrast research.
