Description

La présente invention concerne d'une manière générale les ensembles articulés comportant, globalement, d'une part, deux pièces, dont une, dite ci-après par simple commodité pièce mâle, comporte en saillie au moins un tourillon par lequel elle est en prise à pivotement avec une cuvette prévue de manière complémentaire en creux sur l'autre, dite ci-après par simple commodité pièce femelle, et, d'autre part, un ressort de rappel, qui, intervenant entre ces deux pièces, les sollicite en permanence en direction d'une position relative donnée de repos l'une par rapport à l'autre.The present invention relates generally to articulated assemblies comprising, on the one hand, two parts, one of which, hereinafter called for simple convenience male part, has at least one protruding pin by which it is engaged pivoting with a bowl provided in a complementary hollow on the other, hereinafter called for simple convenience female part, and, on the other hand, a return spring, which, intervening between these two parts, requests them permanently towards a given relative position of rest with respect to each other.

C'est le cas, par exemple, du capot et du volet des boîtiers pour appareillage électrique dans lesquels le corps de boîte contenant l'appareillage électrique est fermé par un capot sur lequel fait surface cet appareillage électrique et auquel est articulé un volet pour la protection de celui-ci au repos.This is the case, for example, of the cover and of the flap of housings for electrical equipment in which the box body containing the electrical equipment is closed by a cover on which this electrical equipment surfaces and to which a flap for the protection of the latter at rest.

Dans les boîtiers de ce type connus à ce jour, l'articulation du volet au capot se fait usuellement par un axe spécifique, qui traverse l'une et l'autre de ces deux pièces, et sur lequel est engagé le ressort de rappel associé.In cases of this type known to date, the articulation of the flap to the cover is usually done by a specific axis, which passes through one and the other of these two parts, and on which is engaged the associated return spring .

Conjointement, ce ressort de rappel est usuellement un simple ressort de torsion, qui, par sa partie médiane de torsion, est engagé sur l'axe précédent, et dont une aile d'extrémité prend appui sur le capot tandis que l'autre porte sur le volet.Together, this return spring is usually a simple torsion spring, which, by its median torsion part, is engaged on the preceding axis, and one end wing of which bears on the cover while the other bears on the blind.

Constituant par lui-même une pièce supplémentaire, l'axe ainsi mis en oeuvre complique le montage de l'ensemble, au détriment des coûts.Constituting by itself an additional part, the axis thus implemented complicates the assembly of the assembly, at the expense of costs.

En particulier, ce montage est difficilement "automatisable".In particular, this assembly is difficult to "automate".

Il est connu par ailleurs d'assurer l'articulation de deux pièces l'une par rapport à l'autre par au moins un tourillon, qui, en saillie sur l'une de ces deux pièces, est en prise à pivotement avec une cuvette prévue de manière complémentaire en creux sur l'autre de celles-ci.It is also known to ensure the articulation of two parts with respect to each other by at least one pin, which, projecting from one of these two parts, is pivotally engaged with a bowl provided in a complementary hollow on the other of these.

Mais, dans le cas où, comme en l'espèce, doit conjointement intervenir un ressort de rappel, le problème se pose de l'implantation et du montage de ce ressort de rappel.But, in the case where, as in the present case, a recall spring must intervene jointly, the problem arises installation and installation of this return spring.

La présente invention a d'une manière générale pour objet une disposition permettant d'apporter une solution particulièrement simple à ce problème.The present invention generally relates to a provision making it possible to provide a particularly simple solution to this problem.

De manière plus précise, elle a tout d'abord pour objet un ensemble articulé, comportant, d'une part, deux pièces, dont une, dite pièce mâle, comporte en saillie au moins un tourillon en prise à pivotement avec une cuvette prévue de manière complémentaire en creux sur l'autre, dite pièce femelle, et, d'autre part, un ressort de rappel, qui, intervenant entre ces deux pièces, les sollicite en permanence en direction d'une position relative donnée de repos l'une par rapport à l'autre, cet ensemble articulé étant d'une manière générale caractérisé en ce que, le ressort de rappel comportant une partie médiane de torsion et de compression et deux ailes d'extrémité dont une, au moins, dite ci-après par simple commodité aile d'accrochage, s'étend latéralement, le tourillon de la pièce mâle est évidé axialement et forme ainsi un logement pour la partie médiane de ce ressort de rappel, en ce que, en bordure d'une échancrure affectant au moins localement ce tourillon, il est prévu un ergot sous lequel peut être engagée l'aile d'accrochage du ressort de rappel, et en ce que, en correspondance avec cette échancrure, la pièce femelle comporte elle-même un évidement, qui recoupe sa cuvette, et dans lequel peut s'engager axialement cette aile d'accrochage du ressort de rappel ; elle vise plus particulièrement, mais non nécessairement exclusivement, le cas des boîtiers pour appareillage électrique dans lesquels un capot et un volet forment l'un avec l'autre un tel ensemble articulé.More specifically, it firstly relates to an articulated assembly, comprising, on the one hand, two parts, one of which, known as the male part, has projecting at least one pin pivotally engaged with a bowl provided with in a complementary manner recessed on the other, called the female part, and, on the other hand, a return spring, which, acting between these two parts, urges them permanently towards a given relative position of rest one relative to the other, this articulated assembly being generally characterized in that, the return spring comprising a median part of torsion and compression and two end wings, one of which, at least, said below for simple convenience, attachment wing extends laterally, the pin of the male part is axially hollowed out and thus forms a housing for the middle part of this return spring, in that, at the edge of a notch affecting at least locally this turn Ilon, there is provided a lug under which can be engaged the latching wing of the return spring, and in that, in correspondence with this notch, the female part itself comprises a recess, which cuts through its bowl, and in which can axially engage this latching wing of the return spring; it relates more particularly, but not necessarily exclusively, to the case of housings for electrical equipment in which a cover and a flap form with each other such an articulated assembly.

Au montage, et la présente invention a encore pour objet le procédé correspondant, le ressort de rappel est d'abord engagé dans le logement prévu pour lui dans la pièce mâle, avec crochetage de son aile d'accrochage sous l'ergot que comporte à cet effet celle-ci, en sorte que cette pièce mâle forme dès lors avec ce ressort de rappel un sous-ensemble unitaire dont la manipulation se trouve ainsi simplifiée, et les deux pièces sont ensuite amenées en prise l'une avec l'autre suivant leur position de repos.During assembly, and the present invention also relates to the corresponding method, the return spring is first engaged in the housing provided for it in the male part, with hooking of its attachment wing under the lug which comprises this effect this, so that this male part therefore forms with this return spring a unitary subassembly whose handling is thus simplified, and the two parts are then brought into engagement with the other according to their rest position.

Il suffit, dès lors, de les écarter l'une de l'autre par rapport à cette position de repos pour que, interférant par l'un des flancs de son évidement avec l'aile d'accrochage du ressort de rappel, la pièce femelle provoque le dégagement de cette aile d'accrochage de l'ergot sous lequel elle était jusqu'alors engagée, et que, ainsi libérée, la partie médiane du ressort de rappel, jusqu'alors soumise à une précontrainte de torsion et de compression, s'engage d'elle-même plus avant dans la cuvette de la pièce femelle, jusqu'à trouver sa place définitive dans celle-ci.It is therefore sufficient to separate them from each other with respect to this rest position so that, interfering with one of the sides of its recess with the latching wing of the return spring, the part female causes the release of this latching wing of the lug under which it was hitherto engaged, and that, thus released, the middle part of the return spring, hitherto subjected to a pretension of torsion and compression, engages itself further into the bowl of the female part, until it finds its final place in it.

Les opérations correspondantes peuvent avantageusement être automatisées, au bénéfice des coûts.The corresponding operations can advantageously be automated, at a cost benefit.

Il en est d'autant plus ainsi que, suivant un développement de l'invention, le tourillon de la pièce mâle est préférentiellement globalement abattu latéralement par un chanfrein pour en permettre un engagement par simple encliquetage dans la cuvette de la pièce femelle.This is all the more so since, according to a development of the invention, the pin of the male part is preferably generally felled laterally by a chamfer to allow engagement by simple snap-fastening in the bowl of the female part.

Ces figures illustrent, à titre d'exemple, l'application de l'invention à un boîtier 10 mis en oeuvre pour le logement d'un appareillage électrique 11, en l'espèce un socle de prise de courant.These figures illustrate, by way of example, the application of the invention to a housing 10 used for housing an electrical apparatus 11, in this case a socket outlet.

De manière connue en soi, ce boîtier 10 comporte un corps de boîte 12, dans lequel est logé le mécanisme de l'appareillage électrique 11, un capot 13 qui ferme le corps de boîte 12, et sur lequel fait surface l'appareillage électrique 11, ainsi qu'il est visible à la figure 2, et, pour la protection de l'appareillage électrique 11 au repos, un volet 14, qui, articulé au capot 13 suivant l'un des bords de celui-ci, se rabat de lui-même sur ce capot 13 au repos.In a manner known per se, this box 10 comprises a box body 12, in which is housed the mechanism of the electrical equipment 11, a cover 13 which closes the box body 12, and on which the electrical equipment 11 surfaces. , as can be seen in FIG. 2, and, for the protection of the electrical apparatus 11 at rest, a flap 14, which, articulated to the cover 13 along one of the edges thereof, folds down itself on this cover 13 at rest.

Dans leurs réalisations propres, le corps de boîte 12, le capot 13 et le volet 14 ne relèvent pas de la présente invention et ils ne seront donc pas décrits en détail ici.In their own embodiments, the box body 12, the cover 13 and the flap 14 do not fall under the present invention and they will therefore not be described in detail here.

Le capot 13 et le volet 14 constituent conjointement, au sens de la présente invention, un ensemble articulé 18.The cover 13 and the flap 14 jointly constitute, within the meaning of the present invention, an articulated assembly 18.

Cet ensemble articulé 18 est du genre comportant, d'une part, deux pièces, dont une, en l'espèce le volet 14, dite ci-après pièce mâle, comporte en saillie au moins un tourillon 20 par lequel elle est en prise à pivotement avec une cuvette 21 prévue de manière complémentaire en creux sur l'autre, en l'espèce le capot 13, dite ci-après pièce femelle, et, d'autre part, un ressort de rappel 22, qui, intervenant entre les pièces 13, 14, les sollicite en permanence en direction d'une position relative donnée de repos l'une par rapport à l'autre, cette position de repos étant en l'espèce celle pour laquelle, tel que représenté à la figure 1, le volet formant la pièce mâle 14 est rabattu sur le capot formant la pièce femelle 13.This articulated assembly 18 is of the type comprising, on the one hand, two parts, one of which, in this case the flap 14, called below male part, projecting at least one pin 20 by which it is pivotally engaged with a bowl 21 provided in a complementary manner hollow on the other, in this case the cover 13, hereinafter called part female, and, on the other hand, a return spring 22, which, acting between the parts 13, 14, urges them permanently towards a given relative position of rest relative to each other, this rest position being in this case that for which, as shown in FIG. 1, the flap forming the male part 14 is folded over the cover forming the female part 13.

Bien entendu, deux tourillons 20, 20' sont en pratique prévus dos à dos sur la pièce mâle 14 en étant chacun respectivement en saillie sur deux bords opposés de celle-ci.Of course, two pins 20, 20 ′ are in practice provided back to back on the male part 14, each projecting respectively on two opposite edges thereof.

Ces tourillons 20, 20' forment conjointement, tel que schématisé en traits interrompus sur les figures 1, 11A et 11B, un axe d'articulation A.These pins 20, 20 ′ jointly form, as shown diagrammatically in broken lines in FIGS. 1, 11A and 11B, an axis of articulation A.

Dans la forme de réalisation représentée, les tourillons 20, 20' sont implantés à la faveur de décrochements 23, 23' que présente la pièce mâle 14 dans deux de ses angles, et, de manière complémentaire, la pièce femelle 13 comporte, dans ses angles correspondants, des bossages 24, 24' dans lesquels sont chacune respectivement implantées les cuvettes 21, 21' correspondantes.In the embodiment shown, the pins 20, 20 ′ are implanted by means of recesses 23, 23 ′ which the male part 14 presents in two of its angles, and, in a complementary manner, the female part 13 comprises, in its corresponding angles, bosses 24, 24 'in which are respectively located the corresponding cups 21, 21'.

En pratique, à la face d'un bossage 24, 24', et, donc, de la pièce femelle 13, sur laquelle est ainsi présente une cuvette 21, 21', se raccorde une facette oblique 25, 25'.In practice, an oblique facet 25, 25 'is connected to the face of a boss 24, 24', and therefore of the female part 13, on which a bowl 21, 21 'is thus present.

Suivant l'invention, le ressort de rappel 22 comportant une partie médiane 26, de torsion et de compression, et deux ailes d'extrémité 27, 27', dont une, au moins, l'aile d'extrémité 27, dite ci-après par simple commodité aile d'accrochage, s'étend latéralement, sensiblement radialement par rapport à la partie médiane 26, le tourillon 20 de la pièce mâle 14 est évidé axialement et forme ainsi un logement 28 pour la partie médiane 26 du ressort de rappel 22, il est prévu, en bordure d'une échancrure 29 affectant au moins localement le tourillon 20, un ergot 30 sous lequel peut être engagée l'aile d'accrochage 27 du ressort de rappel 22, et, en correspondance avec cette échancrure 29, la pièce femelle 13 comporte elle-même un évidement 31, qui recoupe sa cuvette 21, et dans lequel peut s'engager axialement, comme décrit plus en détail ultérieurement, cette aile d'accrochage 27 du ressort de rappel 22.According to the invention, the return spring 22 comprising a central portion 26, of torsion and compression, and two end wings 27, 27 ', including one, at least, the end wing 27, called ci- after for simple convenience attachment wing, extends laterally, substantially radially with respect to the middle part 26, the pin 20 of the male part 14 is axially hollowed out and thus forms a housing 28 for the middle part 26 of the return spring 22, there is provided, at the edge of a notch 29 affecting at least locally the pin 20, a lug 30 under which can be engaged the attachment wing 27 of the return spring 22, and, in correspondence with this notch 29, the female part 13 itself comprises a recess 31, which intersects its bowl 21, and in which can engage axially, as described in more detail later, this attachment wing 27 of the return spring 22 .

Dans la forme de réalisation représentée, le logement 28 du ressort de rappel 22 se prolonge dans la pièce mâle 14 au-delà du tourillon 20, à la faveur d'un bossage interne 32 de cette pièce mâle 14, et il s'agit en pratique d'un logement borgne, figure 7.In the embodiment shown, the housing 28 of the return spring 22 extends into the male part 14 beyond the pin 20, thanks to an internal boss 32 of this male part 14, and it is in practice of a blind housing, figure 7.

Par ailleurs, dans cette forme de réalisation, l'autre aile d'extrémité du ressort de rappel 22, c'est-à-dire son aile d'extrémité 27', s'étend elle aussi latéralement, sensiblement radialement par rapport à la partie médiane 26 de ce ressort de rappel 22, et, en conséquence, le tourillon 20 présente, pour son passage, une fente 33, qui se prolonge tout au long du logement 28, en affectant donc la paroi latérale du bossage interne 32 de la pièce mâle 14.Furthermore, in this embodiment, the other end wing of the return spring 22, that is to say its end wing 27 ', also extends laterally, substantially radially with respect to the middle portion 26 of this return spring 22, and, consequently, the pin 20 has, for its passage, a slot 33, which extends throughout the housing 28, thus affecting the side wall of the internal boss 32 of the male part 14.

Mais, en variante, cette aile d'extrémité 27' pourrait tout aussi bien s'étendre parallèlement à l'axe de la partie médiane 26 du ressort de rappel 22, par exemple suivant une génératrice de celle-ci, et venir alors s'ancrer dans le fond du logement 28.However, as a variant, this end wing 27 ′ could just as easily extend parallel to the axis of the central part 26 of the return spring 22, for example along a generator thereof, and then come anchor in the bottom of the housing 28.

Quoi qu'il en soit, c'est par cette aile d'extrémité 27' que ce ressort de rappel 22 agit sur la partie mâle 14.Anyway, it is by this end wing 27 'that this return spring 22 acts on the male part 14.

Dans la forme de réalisation représentée, l'ergot 30 fait saillie circulairement sur la tranche de l'échancrure 29 du tourillon 20, au débouché du logement 28, suivant une longueur L1 suffisante pour assurer la retenue de l'aile d'accrochage 27 du ressort de rappel 22.In the embodiment shown, the lug 30 projects circularly on the edge of the notch 29 of the pin 20, at the outlet of the housing 28, along a length L1 sufficient to ensure the retention of the attachment wing 27 of the return spring 22.

Il est globalement arrondi, et la portion restante de la tranche de l'encoche 29 est elle-même globalement cintrée.It is generally rounded, and the remaining portion of the edge of the notch 29 is itself generally bent.

Dans la forme de réalisation représentée, le tourillon 20 fait saillie sur une embase 34 qui, de contour circulaire, avec un diamètre supérieur au diamètre extérieur du tourillon 20, fait elle-même saillie sur la face correspondante de la pièce mâle 14.In the embodiment shown, the pin 20 projects from a base 34 which, of circular outline, with a diameter greater than the outside diameter of the pin 20, itself projects from the corresponding face of the male part 14.

L'ensemble est d'un seul tenant avec cette dernière.The whole is in one piece with the latter.

Abstraction faite de l'encoche 29 et de la fente 33, le tourillon 20 est globalement tubulaire.Apart from the notch 29 and the slot 33, the pin 20 is generally tubular.

Dans la forme de réalisation représentée, il est conjointement globalement abattu latéralement par un chanfrein 35, pour son engagement par simple encliquetage dans la cuvette 21 de la pièce femelle 13.In the embodiment shown, it is jointly generally knocked down laterally by a chamfer 35, for its engagement by simple snap-fastening in the bowl 21 of the female part 13.

Le tourillon 20' a, extérieurement, une constitution sensiblement analogue à celle du tourillon 20.The trunnion 20 'has, on the outside, a constitution substantially similar to that of the trunnion 20.

Cependant, au lieu d'être tubulaire comme celui-ci, il est massif.However, instead of being tubular like this, it is massive.

A son raccordement avec la cuvette 21, l'évidement 31 de la pièce femelle 13 a circulairement une largeur L2 au moins égale au diamètre de l'aile d'accrochage 27 du ressort de rappel 22.At its connection with the bowl 21, the recess 31 of the female part 13 has a circular width L2 at least equal to the diameter of the attachment wing 27 of the return spring 22.

En pratique, les flancs de l'évidement 31 s'étendent radialement, en sorte qu'ils s'écartent l'un de l'autre à compter de la cuvette 21.In practice, the sides of the recess 31 extend radially, so that they move away from each other from the bowl 21.

En pratique, également, pour permettre au ressort de rappel 22 de s'y engager, la cuvette 21 de la pièce femelle 13 a, axialement, une profondeur P2 qui, mesurée à compter de son débouché, est supérieure à la profondeur P1 suivant laquelle le tourillon 20 de la pièce mâle 14 y est engagé, figure 11A, et l'évidement 31 qui recoupe cette cuvette 21 s'étend axialement en conséquence.In practice, also, to allow the return spring 22 to engage therein, the cup 21 of the female part 13 has, axially, a depth P2 which, measured from its outlet, is greater than the depth P1 according to which the pin 20 of the male part 14 is engaged therein, FIG. 11A, and the recess 31 which intersects this bowl 21 extends axially as a result.

Dans la forme de réalisation représentée, la cuvette 21 est étagée en deux niveaux, à savoir, à compter de son débouché, un premier niveau de plus grand diamètre D1, pour l'engagement du tourillon 20, et un deuxième niveau de plus petit diamètre D2, pour l'engagement du ressort de rappel 22, figures 9 et 11B.In the embodiment shown, the bowl 21 is stepped in two levels, namely, from its outlet, a first level of larger diameter D1, for the engagement of the pin 20, and a second level of smaller diameter D2, for engaging the return spring 22, Figures 9 and 11B.

En pratique, dans cette forme de réalisation, la partie 36 de la cuvette 21 correspondant à l'engagement du ressort de rappel 22 est formée par des nervures 38 qui, issues de la paroi périphérique de cette cuvette 21, s'étendent radialement, de manière étoilée, en direction de l'axe de celle-ci, et qui, à un même niveau, comportent chacune transversalement un épaulement 39 pour l'appui du ressort de rappel 22.In practice, in this embodiment, the part 36 of the cup 21 corresponding to the engagement of the return spring 22 is formed by ribs 38 which, coming from the peripheral wall of this cup 21, extend radially, from starred manner, in the direction of the axis thereof, and which, at the same level, each have transversely a shoulder 39 for supporting the return spring 22.

Dans la forme de réalisation représentée, les nervures 38 sont au nombre de trois.In the embodiment shown, the ribs 38 are three in number.

Enfin, dans la forme de réalisation représentée, un fût 40 s'étend axialement dans la cuvette 21, à compter du fond de cette cuvette 21 et jusqu'à la partie 36 au moins de celle-ci correspondant à l'engagement du ressort de rappel 22, pour le guidage de celui-ci, et, dans cette partie 36 au moins de la cuvette 21, l'extrémité libre 41 au moins de ce fût 40 est effilée.Finally, in the embodiment shown, a barrel 40 extends axially in the bowl 21, starting from the bottom of this bowl 21 and up to at least part 36 thereof corresponding to the engagement of the spring of reminder 22, for guiding the latter, and, in this part 36 at least of the bowl 21, the free end 41 at least of this barrel 40 is tapered.

Par exemple, l'extrémité libre 41 du fût 40 est globalement tronconique.For example, the free end 41 of the barrel 40 is generally frustoconical.

En pratique, les nervures 38 se raccordent à ce fût 40.In practice, the ribs 38 are connected to this barrel 40.

Au montage, le ressort de rappel 22 est engagé par sa partie médiane 26 dans le logement 28 prévu pour lui sur la pièce mâle 14, suivant la flèche F1 de la figure 3, avec son aile d'extrémité 27' glissée dans la fente 33 du tourillon 20 jusqu'au fond du logement 28.During assembly, the return spring 22 is engaged by its middle part 26 in the housing 28 provided for it on the male part 14, according to the arrow F1 in FIG. 3, with its end wing 27 'slid into the slot 33 from pin 20 to bottom of housing 28.

Le ressort de rappel 22 est ensuite soumis à une torsion, suivant la flèche F2 de la figure 3, jusqu'à ce que son aile d'accrochage 27 arrive au droit de l'échancrure 29 du tourillon 20, puis à une compression suivant la flèche F1 de la figure 3, pour le crochetage de cette aile d'accrochage 27 sous l'ergot 30, comme représenté à la figure 10.The return spring 22 is then subjected to a torsion, along arrow F2 in FIG. 3, until its attachment wing 27 arrives at the level of the notch 29 of the journal 20, then to compression according to the arrow F1 of FIG. 3, for hooking this attachment wing 27 under the lug 30, as shown in FIG. 10.

La pièce mâle 14 forme alors avec le ressort de rappel 22 un sous-ensemble unitaire.The male part 14 then forms with the return spring 22 a unitary sub-assembly.

Dans ce sous-ensemble unitaire, le ressort de rappel 22 est sous précontrainte de torsion et de compression.In this unitary sub-assembly, the return spring 22 is under pretension of torsion and compression.

Les deux pièces mâle 14 et femelle 13 sont ensuite amenées en prise l'une avec l'autre suivant leur position de repos représentée à la figure 1, par simple encliquetage des tourillons 20, 20' de la pièce mâle 14 dans les cuvettes 21, 21' de la pièce femelle 13.The two male 14 and female 13 parts are then brought into engagement with each other according to their rest position shown in FIG. 1, by simple snap-fastening of the pins 20, 20 ′ of the male part 14 in the bowls 21, 21 'of the female part 13.

Ainsi qu'il est aisé de le comprendre, cet encliquetage est facilité par le chanfrein 35 des tourillons 20, 20' de la pièce mâle 14, et/ou par un congé 42 arrondissant l'arête des bossages 24, 24' de la pièce femelle 13.As is easy to understand, this snap-fastening is facilitated by the chamfer 35 of the pins 20, 20 'of the male part 14, and / or by a leave 42 rounding the edge of the bosses 24, 24' of the part female 13.

Au terme de cet encliquetage, la partie de l'aile d'accrochage 27 du ressort de rappel 22 qui fait saillie hors du tourillon 20 de la pièce mâle 14 s'engage dans l'évidement 31 de la pièce femelle 13, tel que schématisé en traits interrompus à la figure 6.At the end of this snap-fastening, the part of the attachment wing 27 of the return spring 22 which projects out of the pin 20 of the male part 14 engages in the recess 31 of the female part 13, as shown schematically in broken lines in Figure 6.

Pour parfaire le montage, il suffit, ensuite, d'écarter l'une de l'autre les pièces mâle 14 et femelle 13, par pivotement autour de leur axe d'articulation A, par exemple en relevant la pièce mâle 14, tel que schématisé par la flèche F3 sur la figure 2.To complete the assembly, it suffices, then, to separate the male parts 14 and female parts 13 from one another, by pivoting about their articulation axis A, for example by raising the male part 14, such that shown diagrammatically by arrow F3 in FIG. 2.

Retenue par le flanc correspondant de l'évidement 31 de la pièce femelle 13, l'aile d'accrochage 27 du ressort de rappel 22 échappe alors à l'ergot 30 de la pièce mâle 14, en sorte que, sous l'effet de la précontrainte de compression à laquelle il était jusqu'alors soumis, le ressort de rappel 22 s'engage de lui-même axialement dans la cuvette 21 de la pièce femelle 13, jusqu'à venir porter par sa partie médiane 26 contre les épaulements 39 des nervures 38 présentes dans celle-ci, comme représenté à la figure 11B.Retained by the corresponding side of the recess 31 of the female part 13, the attachment wing 27 of the return spring 22 then escapes the lug 30 of the male part 14, so that, under the effect of the compression preload to which it was previously subjected, the return spring 22 engages itself axially in the bowl 21 of the female part 13, until it comes to bear by its middle part 26 against the shoulders 39 ribs 38 present therein, as shown in Figure 11B.

En service, le ressort de rappel 22 coopère par son aile d'accrochage 27 avec la pièce femelle 13 et par son autre aile d'extrémité 27' avec la pièce mâle 14, et il sollicite donc en permanence ces deux pièces 13, 14 en direction de leur position de repos représentée à la figure 1.In service, the return spring 22 cooperates by its attachment wing 27 with the female part 13 and by its other end wing 27 'with the male part 14, and it therefore permanently biases these two parts 13, 14 in direction of their rest position shown in Figure 1.

Ainsi qu'il est aisé de le comprendre, les facettes obliques 25, 25' des bossages 24, 24' de la pièce femelle 13 offrent avantageusement un dégagement lors d'une ouverture du volet formant la pièce mâle 14.As is easy to understand, the oblique facets 25, 25 ′ of the bosses 24, 24 ′ of the female part 13 advantageously provide clearance when the shutter forming the male part 14 is opened.

Bien entendu, la présente invention ne se limite pas à la forme de réalisation décrite et représentée mais englobe toute variante d'exécution.Of course, the present invention is not limited to the embodiment described and shown, but encompasses any variant.

Son domaine d'application n'est pas non plus limité aux seuls boîtiers pour appareillage électrique du type de celui plus particulièrement décrit et représenté.Its field of application is not limited to only housings for electrical apparatus of the type more particularly described and shown.
