Abstract

The mechanism (13) has a control handle (40) pivotably moved in a door (12), where the mechanism occupies a door releasing configuration in which a bolt (41) is in an unlocked position and the handle is in an unlocked position. The handle is driven against an elastic return unit i.e. spring, by a user from a rest position to its unlocked position. The bolt remains in a locked position until that a bearing surface (79) of the handle is in contact with a bearing surface (78) of the bolt. The bolt is driven against the return unit by the handle until its unlocked position.

Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

L'invention a trait aux mécanismes de fermeture de porte, en particulier, mais non exclusivement, dans les enveloppes pour appareils électriques.The invention relates to door closing mechanisms, in particular, but not exclusively, in enclosures for electrical appliances.

ARRIERE PLAN TECHNOLOGIQUEBACKGROUND TECHNOLOGY

On connaît déjà de nombreux mécanismes de fermeture de porte où il faut agir sur la poignée pour déplacer le pêne lors de la fermeture et lors de l'ouverture de la porte.Many door closing mechanisms are already known where it is necessary to act on the handle to move the bolt during closing and when opening the door.

On a déjà proposé diverses solutions pour que la fermeture de la porte puisse s'opérer sans avoir à manoeuvrer la poignée.Various solutions have already been proposed so that the closing of the door can take place without having to maneuver the handle.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

L'invention vise à fournir un tel mécanisme de fermeture, qui soit particulièrement simple, commode et économique.The invention aims to provide such a closure mechanism, which is particularly simple, convenient and economical.

Elle propose à cet effet un mécanisme de fermeture de porte comportant, sur ladite porte, une poignée de commande et un pêne, et comportant, sur une portion dormante sur laquelle est montée ladite porte, un organe de retenue ; caractérisé en ce que ledit mécanisme admet :

  • une configuration porte ouverte où ladite poignée et ledit pêne sont chacun dans une position de repos où ils sont appliqués contre une butée de fin de course respective par un moyen de rappel élastique respectif ;
  • une configuration porte fermée où ladite poignée est dans la position de repos et ledit pêne est dans une position de verrouillage où il est engagé à accrochage avec ledit organe de retenue, avec, au cours du passage entre la configuration porte ouverte et la configuration porte fermée, la poignée qui reste en position de repos et le pêne qui est entraîné, à l'encontre de son moyen de rappel élastique, au contact dudit organe de retenue, vers une position de franchissement dudit organe de retenue puis entraîné par son moyen de rappel élastique vers ladite position de verrouillage ; et
  • une configuration de libération de porte où le pêne est dans une position de déverrouillage où il est dégagé de l'organe de retenue et ladite poignée est dans une position de déverrouillage où une surface d'appui que comporte la poignée est contre une surface d'appui que comporte le pêne, avec, au cours du passage entre la configuration porte fermée et la configuration porte ouverte, la poignée qui est entraînée, à l'encontre de son moyen de rappel élastique, par un utilisateur, de sa position de repos à sa position de déverrouillage, et le pêne qui reste dans la position de verrouillage jusqu'à ce que la surface d'appui de la poignée soit venue au contact de la surface d'appui du pêne, lequel est alors entraîné, à l'encontre de son moyen de rappel élastique, par la poignée, jusqu'à sa position de déverrouillage.
It proposes for this purpose a door closing mechanism comprising, on said door, a control handle and a bolt, and comprising, on a dormant portion on which is mounted said door, a retaining member; characterized in that said mechanism admits:
  • an open door configuration where said handle and said bolt are each in a rest position where they are applied against a respective end stop by a respective elastic return means;
  • a closed door configuration where said handle is in the rest position and said bolt is in a locking position where it is engaged to hook with said retaining member, with, during the passage between the open door configuration and the closed door configuration , the handle which remains in the rest position and the bolt which is driven, against its elastic return means, in contact with said retaining member, to a position for crossing said retaining member and then driven by its return means elastic to said locking position; and
  • a door release configuration where the bolt is in an unlocked position where it is disengaged from the retaining member and said handle is in an unlocked position where a bearing surface that includes the handle is against a surface of support that includes the bolt, with, during the passage between the closed door configuration and the open door configuration, the handle which is driven, against its resilient biasing means, by a user, its rest position to its unlocking position, and the bolt which remains in the locking position until the bearing surface of the handle has come into contact with the bearing surface of the bolt, which is then driven, against its elastic return means, by the handle, to its unlocked position.

Le fait que le pêne et la poignée soient chacun munis de son propre moyen de rappel élastique et de sa propre butée de fin de course et la façon dont la poignée et le pêne sont mobiles lors des changements de configuration rend possible la mise en oeuvre du mécanisme de fermeture de porte avec un nombre de composants particulièrement réduit.The fact that the bolt and the handle are each provided with its own elastic return means and its own limit stop and the manner in which the handle and the bolt are movable during configuration changes makes it possible to implement the door closing mechanism with a particularly small number of components.

Ainsi, si l'on prévoit qu'un berceau de montage est ménagé dans la porte, le mécanisme selon l'invention peut être mise en oeuvre avec uniquement la poignée, le pêne et les moyens de rappel élastique.Thus, if it is expected that a mounting cradle is provided in the door, the mechanism according to the invention can be implemented with only the handle, the bolt and the elastic return means.

Selon des caractéristiques préférées, le mécanisme comporte sur ladite porte un berceau de montage comportant une platine.According to preferred features, the mechanism comprises on said door a mounting cradle comprising a plate.

Un tel berceau permet de mettre en oeuvre le mécanisme de fermeture de porte de façon particulièrement performante, tant à la fabrication qu'à l'utilisation.Such a cradle makes it possible to implement the door closing mechanism in a particularly efficient manner, both in manufacture and use.

De préférence, pour les mêmes raisons :

  • ladite poignée et ledit pêne comportent chacun une platine avec la platine de la poignée et la platine du pêne qui sont de part et d'autre de la platine du berceau ;
  • ladite surface d'appui d'au moins un parmi la poignée et le pêne fait partie d'une patte d'appui saillante, la platine du berceau présentant une ouverture de passage pour ladite patte d'appui ;
  • ladite patte d'appui fait partie dudit pêne, ladite surface d'appui dudit pêne étant formée par une surface distale de ladite patte d'appui ;
  • ladite surface d'appui de ladite poignée est formée par une tranche de sa platine ;
  • la platine du berceau, la platine de la poignée et la platine du pêne sont de longueur semblable ;

  • la portion dormante présente une gouttière recevant la platine du pêne en configuration porte fermée ; et/ou
  • ledit organe de retenue saille du versant interne de ladite gouttière tandis qu'un renfoncement d'accès à ladite poignée est ménagé dans le versant externe de ladite gouttière.
Preferably, for the same reasons:
  • said handle and said bolt each comprise a plate with the plate of the handle and the plate of the bolt which are on either side of the plate of the cradle;
  • said bearing surface of at least one of the handle and the bolt is part of a protruding support lug, the platen of the cradle having a passage opening for said support lug;
  • said support leg is part of said bolt, said bearing surface of said bolt being formed by a distal surface of said support leg;
  • said bearing surface of said handle is formed by a slice of its plate;
  • the deck of the cradle, the plate of the handle and the plate of the bolt are of similar length;
  • the cradle plate is oriented parallel to the general orientation plane of the door; in said rest position, the plate of the handle is oriented parallel to the general orientation plane of the door; and in the rest position, the plate of the bolt is oriented transversely to the general orientation plane of the door;
  • the dormant portion has a gutter receiving the platen of the bolt in closed door configuration; and or

DESCRIPTION DETAILLEE D'UN EXEMPLE DE REALISATIONDETAILED DESCRIPTION OF AN EXEMPLARY EMBODIMENT

Le capot de coffret 10 illustré sur les dessins comporte une portion dormante 11 prévue pour être assujettie de façon rigide à un corps de coffret (non représenté), une porte 12 articulée sur la portion dormante le long de son côté opposé à celui visible sur les figures 1, 3 et 4 ; et un mécanisme 13 de fermeture de la porte 12.The cabinet cover 10 illustrated in the drawings comprises a dormant portion 11 intended to be rigidly attached to a cabinet body (not shown), a door 12 articulated on the dormant portion along its side opposite to that visible on the figures 1 , 3 and 4 ; and a mechanism 13 for closing the door 12.

Ici, le capot 10 est prévu pour fermer un corps de coffret muni de deux rails de fixation pour des appareils électriques modulaires, tels que des interrupteurs différentiels et des disjoncteurs, afin que l'on puisse installer dans ce corps deux rangées chacune formée par un ensemble d'appareils électriques modulaires disposés côte à côte sur l'un des rails.Here, the cover 10 is designed to close a box body provided with two fixing rails for modular electrical devices, such as differential switches and circuit breakers, so that two rows each formed by a box can be installed in this body. set of modular electrical appliances arranged side by side on one of the rails.

La portion dormante 11 du capot 10 présente un panneau central 14 dans lequel sont ménagées deux fenêtres allongées 15 chacune obturée par un opercule 16.The dormant portion 11 of the cover 10 has a central panel 14 in which are formed two elongated windows 15 each closed by a cover 16.

Chaque fenêtre 15 est prévue pour permettre le passage des nez des appareils électriques disposés en rangée sur l'un des rails. Suivant le nombre d'appareils électriques installés, les opercules 16 sont enlevées en totalité ou en partie.Each window 15 is provided to allow the passage of the nose of electrical appliances arranged in a row on one of the rails. Depending on the number of electrical devices installed, the covers 16 are removed in whole or in part.

Le panneau central 14 est longé sur la totalité de son pourtour, qui est ici globalement rectangulaire avec les angles arrondis, par un rebord saillant 17.Central panel 14 is skirted over its entire periphery, which here is generally rectangular with rounded corners, by a protruding flange 17.

Le rebord 17 est entouré par un rebord périphérique 18, qui délimite le pourtour de la portion dormante 11, lequel pourtour, tout comme le pourtour du panneau 14, est globalement rectangulaire à angles arrondis.The flange 17 is surrounded by a peripheral flange 18, which delimits the periphery of the dormant portion 11, which periphery, like the periphery of the panel 14, is generally rectangular with rounded corners.

L'espace situé entre le rebord interne 17 et le rebord périphérique 18 forme une gouttière 19.The space between the inner rim 17 and the peripheral rim 18 forms a gutter 19.

Le versant de la gouttière 19 formé par le rebord interne 17 est moins élevé que le versant formé par le rebord périphérique 18, la tranche 20 du rebord interne 17 étant en retrait par rapport à la tranche 21 du rebord périphérique 18.The slope of the trough 19 formed by the internal rim 17 is less than the slope formed by the peripheral rim 18, the edge 20 of the inner rim 17 being recessed with respect to the edge 21 of the peripheral rim 18.

Ici, la tranche 20 est formée par un bourrelet d'un joint d'étanchéité 22 que comporte le rebord interne 17.Here, the wafer 20 is formed by a bead of a seal 22 that includes the internal rim 17.

Le capot 10 est prévu pour venir en appui sur le corps de coffret (non représenté) par sa tranche 23 situé en bout d'une paroi latérale située au droit de la paroi externe du rebord périphérique 18.The cover 10 is provided to bear on the casing body (not shown) by its edge 23 located at the end of a side wall located at the right of the outer wall of the peripheral flange 18.

Le verrouillage du capot 10 s'effectue grâce à des cheminées 24. Lorsque le capot 10 est en place sur le corps, chaque cheminée 24 est alignée avec une cheminée du corps, de sorte que, pour chaque couple de cheminées, la tige d'une vis de verrouillage peut passer de l'alésage de la cheminée 24 à celui de la cheminée du corps pour s'y mettre en prise.The cover 10 is locked by means of chimneys 24. When the cover 10 is in place on the body, each chimney 24 is aligned with a chimney of the body, so that, for each pair of chimneys, the rod of a locking screw can pass from the bore of the chimney 24 to that of the chimney of the body to engage with it.

La porte 12 comporte un panneau central 25 sur le pourtour duquel se trouve un rebord 26 ayant globalement le même contour que le rebord interne 17. La tranche 27 du rebord 26 est relativement étroite et vient en appui, lorsque la porte 12 est fermée, sur le joint 22 formant la tranche 20 (voir plus particulièrement la figure 5).The door 12 comprises a central panel 25 around the edge of which is a flange 26 having generally the same contour as the inner flange 17. The edge 27 of the flange 26 is relatively narrow and bears, when the door 12 is closed, on the seal 22 forming the wafer 20 (see more particularly the figure 5 ).

Le long de son côté illustré sur les figures 1, 3 et 4, la porte 12 présente un berceau 30 de montage du mécanisme de fermeture 13.Along its side illustrated on figures 1 , 3 and 4 the door 12 has a cradle 30 for mounting the closure mechanism 13.

Le berceau 30 comporte une platine 31, une contre-platine 32, deux joues 33, une façade 34 et un ressaut 35.The cradle 30 comprises a plate 31, a counterplate 32, two cheeks 33, a frontage 34 and a projection 35.

La platine 31 est orientée parallèlement au plan d'orientation générale de la porte 12.The plate 31 is oriented parallel to the general orientation plane of the door 12.

La contre-platine 32 et les joues 33 saillent transversalement de la platine 31 vers l'opposé de la portion dormante 11.Counterplate 32 and cheeks 33 protrude transversely from plate 31 towards the opposite of dormant portion 11.

Ici, la platine 31 a un contour globalement en forme de trapèze isocèle dont les côtés opposés non parallèles seraient arrondis.Here, the plate 31 has a contour generally isosceles trapezium whose opposite non-parallel sides are rounded.

Le plus grand des deux côtés parallèles appartient au pourtour de la porte 12.The larger of the two parallel sides belongs to the periphery of the door 12.

La contre-platine 32 s'étend le long du plus petit des côtés parallèles et chaque joue 33 s'étend le long d'un respectif des côtés non parallèles.Backplate 32 extends along the smaller of the parallel sides and each flange 33 extends along a respective non-parallel side.

La contre-platine 32 et les joues 33 forment une paroi continue qui borde la platine 31 le long de ses côtés en retrait par rapport au pourtour de la porte 12.The counterplate 32 and the flanges 33 form a continuous wall which borders the plate 31 along its recessed sides with respect to the periphery of the door 12.

La façade 34 saille transversalement de la platine 31 le long de son côté appartenant au pourtour de la porte 12 (plus grand des deux côtés parallèles), vers la portion dormante 11, c'est-à-dire que la façade 34 saille de la platine 31 de sa face opposée à celle dont saille la contre-platine 32 et les joues 33.The facade 34 protrudes transversely from the plate 31 along its side belonging to the periphery of the door 12 (larger of the two parallel sides), towards the dormant portion 11, that is to say that the facade 34 protrudes from the platinum 31 of its opposite face to that which counter platinum 32 and the cheeks 33.

De part et d'autre de la platine 31, à partir de chacune des joues 33, la façade 34 se prolonge par une paroi située au même niveau que la joue 33 correspondante, à laquelle elle se raccorde.On either side of the plate 31, from each of the cheeks 33, the facade 34 is extended by a wall located at the same level as the corresponding cheek 33, to which it is connected.

Le ressaut 35 comporte une portion en regard de la platine 31. Cette portion saille transversalement du côté de la contre-platine 32 et des joues 33 opposé à celui par lequel la contre-platine 32 et les joues 33 se raccordent à la platine 31. Le ressaut 35 comporte en outre, de part et d'autre de la platine 31, une portion s'étendant au-delà de la joue 33 correspondante et se raccordant à la façade 34 (voir plus particulièrement la figure 7).The projection 35 has a portion opposite the plate 31. This portion projects transversely towards the side of the backplate 32 and the cheeks 33 opposite to that by which the backplate 32 and the cheeks 33 are connected to the plate 31. The projection 35 further comprises, on either side of the plate 31, a portion extending beyond the corresponding cheek 33 and connecting to the front 34 (see more particularly the figure 7 ).

La portion du ressaut 35 en regard de la platine 31 est en retrait par rapport à la façade 34 avec globalement la forme d'une bande étroite longeant la contre-platine 32.The portion of the projection 35 opposite the plate 31 is set back with respect to the facade 34 with generally the shape of a narrow band along the backplate 32.

Comme on le voit notamment sur les figures 2, 5 et 9, cette bande étroite est inclinée vers l'opposé de la platine 31.As we see in particular on figures 2 , 5 and 9 this narrow band is inclined towards the opposite of the plate 31.

Le berceau 30 forme, d'une part, un renfoncement central 36 délimité par la platine 31, la contre-platine 32, les joues 33 et le ressaut 35 ; et, d'autre part, deux renfoncements latéraux 37 chacun délimité par la façade 34 et par le ressaut 35.The cradle 30 forms, on the one hand, a central recess 36 delimited by the plate 31, the counterplate 32, the cheeks 33 and the projection 35; and, on the other hand, two lateral recesses 37 each delimited by the facade 34 and the projection 35.

Le renfoncement central 36 est ouvert vers l'opposé de la portion dormante 11 et les renfoncements latéraux 37 sont ouverts vers la portion dormante 11.The central recess 36 is open towards the opposite of the dormant portion 11 and the lateral recesses 37 are open towards the dormant portion 11.

Le mécanisme 13 comporte une poignée de commande 40, un pêne 41, un ressort 42 de rappel de la poignée 40 et deux ressorts 43 de rappel du pêne 41.The mechanism 13 comprises a control handle 40, a bolt 41, a spring 42 for returning the handle 40 and two springs 43 for returning the bolt 41.

La poignée 40 comporte une platine 45 et deux jambages 46, chacun situé à une extrémité respective de la platine 45.The handle 40 comprises a plate 45 and two legs 46, each located at a respective end of the plate 45.

La platine 45 est allongée avec ses extrémités étroites opposées qui sont arrondies.The plate 45 is elongate with its opposite narrow ends which are rounded.

Du côté que l'on voit à gauche sur les figures 1, 3 et 4, la platine 45 présente un opercule défonçable 47, ici à contour circulaire. Entre l'opercule 47 et l'extrémité opposée, la platine 45 présente une ouverture allongée 48.On the side that we see on the left on figures 1 , 3 and 4 the plate 45 has a knockout seal 47, here circular contour. Between the seal 47 and the opposite end, the plate 45 has an elongated opening 48.

Le jambage 46 que l'on voit à gauche de la poignée 40 sur la figure 1 saille de la platine 45 vers la portion dormante 11. Il est muni d'un tourillon d'articulation 49 orienté parallèlement à la direction générale d'allongement de la platine 45. Dans le tourillon 49 est ménagé un alésage coaxial 50.The jamb 46 that is seen to the left of the handle 40 on the figure 1 it moves from the plate 45 to the dormant portion 11. It is provided with a hinge pin 49 oriented parallel to the general direction of elongation of the plate 45. In the pin 49 is formed a coaxial bore 50.

L'autre jambage 46 que comporte la poignée 40 à l'extrémité que l'on voit à droite sur la figure 1 est identique, si ce n'est qu'il en est l'image miroir.The other leg 46 that includes the handle 40 at the end that is seen to the right on the figure 1 is identical, except that it is the mirror image.

On notera en particulier que les deux tourillons 49 sont alignés parallèlement à la direction générale suivant laquelle s'allonge la platine 45, de façon excentrée ; et que le tourillon 49 de chacun des deux jambages 46 saille vers l'extérieur de la poignée 40.It will be noted in particular that the two pins 49 are aligned parallel to the general direction along which the plate 45 extends, eccentrically; and that the trunnion 49 of each of the two legs 46 protrudes towards the outside of the handle 40.

Les jambages 46 sont légèrement flexibles élastiquement afin de pouvoir être rapprochés l'un de l'autreThe legs 46 are slightly elastically flexible in order to be closer to one another

Cela permet l'encliquetage de la poignée 40 dans le berceau 30, qui présente pour chaque tourillon 49 une ouverture 51 dont le pourtour forme palier.This allows the latching of the handle 40 in the cradle 30, which has for each trunnion 49 an opening 51 whose perimeter form bearing.

Chaque ouverture 51 est ménagée dans une respective des joues 33, à partir de la platine 31 et à partir de la façade 34. L'ouverture 51 comporte également une légère encoche dans la façade 34.Each opening 51 is formed in a respective cheeks 33, from the plate 31 and from the front 34. The opening 51 also has a slight notch in the facade 34.

Lorsque la poignée 40 est encliquetée dans le berceau 30, elle peut pivoter autour des tourillons 49 entre la position rabattue illustrée sur les figures 2, 3 et 5 à 8 ; et la position relevée illustrée sur les figures 4, 9 et 10.When the handle 40 is snapped into the cradle 30, it can pivot about the journals 49 between the folded position illustrated in FIGS. figures 2 , 3 and 5 to 8 ; and the raised position illustrated on the figures 4 , 9 and 10 .

Dans la position rabattue, la platine 45 de la poignée 40 est orientée parallèlement à la platine 31 du berceau 30, et donc parallèlement au plan d'orientation générale de la porte 12. La surface externe de la platine 45 est alors sensiblement à fleur de la tranche du ressaut 35 tandis qu'environ la moitié de la platine 45, située au-delà des jambages 46, est en débord de la surface externe de la façade 34.In the folded position, the plate 45 of the handle 40 is oriented parallel to the plate 31 of the cradle 30, and therefore parallel to the general orientation plane of the door 12. The outer surface of the plate 45 is then substantially flush with the edge of the projection 35 while about half of the plate 45, located beyond the legs 46, is in excess of the outer surface of the facade 34.

Dans la position relevée, la platine 45 est inclinée vers la platine 31 et vers la contre-platine 32.In the raised position, the plate 45 is inclined towards the plate 31 and towards the backplate 32.

Pour faire passer la poignée 40 de la position rabattue à la position relevée il faut tirer sur la portion de la platine 45 en saillie de la surface externe de la façade 34.To move the handle 40 from the folded position to the raised position must pull the portion of the plate 45 projecting from the outer surface of the facade 34.

Pour loger la partie saillante de la platine 45 et pour permettre à la main d'un utilisateur de venir chercher la face arrière de cette portion saillante afin de relever la poignée 40, le rebord 18 de la portion dormante 11 présente un renfoncement 55 en correspondance avec le renfoncement 36 du berceau 30, lorsque la porte 12 est fermée (voir plus particulièrement la figure 4).To accommodate the projecting portion of the plate 45 and to allow the hand of a user to come to the rear face of this protruding portion to raise the handle 40, the rim 18 of the dormant portion 11 has a recess 55 in correspondence with the recess 36 of the cradle 30, when the door 12 is closed (see more particularly the figure 4 ).

Pour que la poignée 40 ne puisse pivoter qu'entre la position rabattue et la position relevée, elle est munie, ici au centre de la paroi latérale de la platine 45 en regard de la contre-platine 32, d'un ergot 56 présentant une face droite 57 tournée vers le ressaut 35 et une face inclinée 58 tournée vers la platine 31. Les faces 57 et 58 forment des butées de fin de course fixant respectivement la position rabattue et la position relevée (voir plus particulièrement la figure 2).So that the handle 40 can pivot only between the folded position and the raised position, it is provided, here at the center of the side wall of the plate 45 opposite the counter plate 32, a lug 56 having a right face 57 turned towards the projection 35 and an inclined face 58 facing the plate 31. The faces 57 and 58 form end stops respectively fixing the folded position and the raised position (see more particularly the figure 2 ).

Dans la position rabattue, la face 57 est en appui contre un redan 59 saillant de la contre-platine 32 et du ressaut 35.In the folded position, the face 57 is in abutment against a recess 59 protruding from the backplate 32 and the projection 35.

Dans la position relevée, la face 58 est en appui contre la platine 31.In the raised position, the face 58 bears against the plate 31.

Le ressort 42 est fait en fil à ressort avec une portion centrale hélicoïdale 60 dont une extrémité se raccorde à une patte 61 et l'autre extrémité à une patte 62, les pattes 61 et 62 étant disposées transversalement l'une par rapport à l'autre lorsque le ressort 42 est au repos (figure 1).The spring 42 is made of spring wire with a helical central portion 60, one end of which connects to a tab 61 and the other end to a tab 62, the tabs 61 and 62 being arranged transversely relative to one another. other when the spring 42 is at rest ( figure 1 ).

Ainsi qu'on le voit sur la figure 8, lorsque la poignée 40 et le ressort 42 sont montés dans le berceau 30, la patte 61 est en appui sur la platine 31 du berceau 30 et la patte 62 sur la platine 45 de la poignée 40.As we see on the figure 8 when the handle 40 and the spring 42 are mounted in the cradle 30, the tab 61 bears on the plate 31 of the cradle 30 and the tab 62 on the plate 45 of the handle 40.

Pour maintenir le ressort 42, la platine 45 présente un logement 63 pour la portion centrale 60 et une encoche 64 pour la patte 62 tandis que la platine 31 est munie de deux nervures 66 entre lesquelles est engagée la patte 61.To maintain the spring 42, the plate 45 has a housing 63 for the central portion 60 and a notch 64 for the tab 62 while the plate 31 is provided with two ribs 66 between which is engaged the tab 61.

Avant encliquetage de la poignée 40 dans le berceau 30, la portion centrale 60 et la patte 62 sont engagées respectivement dans le logement 63 et dans l'encoche 64. La patte 61 est mise en place entre les nervures 66 en même temps que la poignée 40 est encliquetée dans le berceau 30.Before snapping of the handle 40 in the cradle 30, the central portion 60 and the lug 62 are respectively engaged in the housing 63 and in the notch 64. The lug 61 is placed between the ribs 66 at the same time as the handle 40 is snapped into the cradle 30.

Le ressort 42 sollicite la poignée 40 vers la position rabattue où la face 57 de l'ergot 56 est en appui contre le redan 59.The spring 42 urges the handle 40 towards the folded position where the face 57 of the lug 56 bears against the step 59.

Le pivotement de la poignée 40 de la position rabattue à la position relevée s'effectue à l'encontre du ressort 42, lequel rappelle la poignée 40 vers la position rabattue lorsque plus aucun effort n'est exercé sur celle-ci.The pivoting of the handle 40 from the folded position to the raised position is effected against the spring 42, which recalls the handle 40 to the folded position when no more effort is exerted on it.

Le pêne 41 comporte une platine 70, deux jambages 71 chacun situé à une extrémité respective de la platine 70, et deux pattes 72 d'appui avec la poignée 40, situées à distance l'une de l'autre entre les jambages 71.The bolt 41 comprises a plate 70, two legs 71 each located at a respective end of the plate 70, and two tabs 72 of support with the handle 40, located at a distance from one another between the legs 71.

Le pêne 41 a une longueur semblable à celle de la poignée 40 et de la platine 31.The bolt 41 has a length similar to that of the handle 40 and the plate 31.

La platine 70 est globalement rectangulaire.The plate 70 is generally rectangular.

Elle forme, à partir de celui de ses grands côtés que l'on voit en bas sur les dessins, un cran 75 permettant son accrochage sur la portion dormante 11, qui est ici munie à cet effet de deux dents d'accrochage 76 dont l'une est visible sur la figure 1 et l'autre sur les figures 6 et 10.It forms, from that of its long sides that can be seen below in the drawings, a notch 75 allowing its attachment to the dormant portion 11, which is here provided for this purpose with two attachment teeth 76 of which one is visible on the figure 1 and the other on the figures 6 and 10 .

Les jambages 71 saillent du grand côté de la platine 70 opposé à celui formant une extrémité du cran 75.The legs 71 project from the long side of the plate 70 opposite that forming one end of the notch 75.

Chaque jambage 71 est muni d'un tourillon d'articulation 77 orienté parallèlement à la direction générale suivant laquelle s'allonge la platine 70. Les tourillons 77 sont alignés. Ils saillent chacun vers l'extrémité du pêne 41 que l'on voit à droite sur la figure 1. Chaque tourillon 77 présente un diamètre correspondant à celui de l'alésage 50 des tourillons 49.Each leg 71 is provided with a hinge pin 77 oriented parallel to the general direction along which the plate 70 extends. The pins 77 are aligned. They project each towards the end of the bolt 41 that is seen to the right on the figure 1 . Each pin 77 has a diameter corresponding to that of the bore 50 of the journals 49.

Comme on le voit sur la figure 7, lorsque le mécanisme 13 est assemblé, chaque tourillon 77 est engagé dans l'alésage 50 de l'un des tourillons 49, le pêne 41 étant ainsi mobile à pivotement coaxialement à la poignée 40.As we see on the figure 7 when the mechanism 13 is assembled, each pin 77 is engaged in the bore 50 of one of the journals 49, the bolt 41 being thus pivotally movable coaxially with the handle 40.

De même que les jambages 71, les pattes d'appui 72 saillent de la platine 70 depuis le grand côté opposé à celui formant une extrémité du cran 75.Like the jambs 71, the bearing lugs 72 project from the plate 70 from the long side opposite that forming one end of the notch 75.

Chaque patte 72 a la forme d'une équerre dont la branche distale est orientée transversalement à la platine 70. La surface d'extrémité distale 78 de chaque patte 72 forme une surface d'appui pour la poignée 40, ici prévue pour venir en contact avec la tranche 79 de la paroi latérale de la platine 45 (figure 9).Each tab 72 has the shape of a bracket whose distal branch is oriented transversely to the plate 70. The distal end surface 78 of each tab 72 forms a bearing surface for the handle 40, here intended to come into contact with the slice 79 of the side wall of the plate 45 ( figure 9 ).

Pour le passage des pattes d'appui 72, la platine 31 présente deux ouvertures 80.For the passage of the support legs 72, the plate 31 has two openings 80.

Pour le passage du jambage 71 que l'on voit à droite sur la figure 1, la platine 31 présente une ouverture 81 à proximité de l'ouverture 51 correspondante.For the passage of the jamb 71 that we see on the right on the figure 1 the plate 31 has an opening 81 near the corresponding opening 51.

Le pêne 41 est mis en place après la poignée 40, de la façon expliquée ci-après.The bolt 41 is put in place after the handle 40, as explained below.

Le pêne 70 est d'abord placé dans une position où le jambage 71 que l'on voit à droite sur la figure 1 est en regard de l'ouverture 81, chacune des pattes d'appui 72 est en regard de l'une des ouvertures 80 et le jambage 71 que l'on voit à gauche sur la figure 1 est en regard du renfoncement latéral 37 que l'on voit à gauche.The bolt 70 is first placed in a position where the jamb 71 that is seen to the right on the figure 1 is opposite the opening 81, each of the support lugs 72 is opposite one of the openings 80 and the jamb 71 that is seen to the left on the figure 1 is next to the lateral recess 37 that we see on the left.

Le pêne 41 est alors rapproché de la platine 31, jusqu'à ce que les tourillons 77 des jambages 71 soient alignés avec les tourillons 49 de la poignée 40 puis le pêne 41 est déplacé selon la direction d'alignement pour engager les tourillons 77 dans les alésages 50.The bolt 41 is then brought closer to the plate 31, until the trunnions 77 of the legs 71 are aligned with the trunnions 49 of the handle 40 and the bolt 41 is moved in the alignment direction to engage the trunnions 77 in the bores 50.

A la fin de ce mouvement d'engagement, une queue 85 que comporte chaque ressort 43 s'engage dans une empreinte 86 de la façade 34 (figure 7 et 8).At the end of this engagement movement, a tail 85 which each spring 43 comprises engages in an impression 86 of the facade 34 ( figure 7 and 8 ).

L'encliquetage des queues 85 dans les empreintes 86 empêche le retrait du pêne 41, qui est ainsi maintenu en place.The snapping of the tails 85 into the cavities 86 prevents the removal of the bolt 41, which is thus held in place.

Le montage du mécanisme 13 est alors terminé.The assembly of the mechanism 13 is then completed.

Le pêne 41 est mobile à pivotement, coaxialement à la poignée 40, entre la position de repos illustrée sur la figure 2 (mécanisme 13 en configuration porte ouverte) et la position de déverrouillage illustrée sur les figures 9 et 10 (configuration de libération de porte).The bolt 41 is pivotally movable, coaxially with the handle 40, between the rest position illustrated on the figure 2 (mechanism 13 in the open door configuration) and the unlocking position illustrated on the Figures 9 and 10 (door release configuration).

Dans la position de repos, la platine 70 du pêne 41 est orientée transversalement à la platine 31 du berceau 30 et donc transversalement au plan d'orientation générale de la porte 12.In the rest position, the plate 70 of the bolt 41 is oriented transversely to the plate 31 of the cradle 30 and therefore transversely to the general orientation plane of the door 12.

Les ressorts 43 sollicitent le pêne 41 vers la position de repos (figure 2).The springs 43 urge the bolt 41 towards the rest position ( figure 2 ).

Chaque ressort 43 est fait en fil à ressort avec une portion centrale hélicoïdale 90 dont une extrémité se raccorde à une patte 91 et l'autre extrémité à une patte 92. L'extrémité de la patte 91 opposée à la portion centrale 90 se raccorde à la queue 85. Les pattes 91 et 92 sont parallèles l'une à l'autre lorsque le ressort 43 est au repos (figure 1).Each spring 43 is made of spring wire with a helical central portion 90, one end of which connects to a tab 91 and the other end to a tab 92. The end of the tab 91 opposite the central portion 90 is connected to the tail 85. The tabs 91 and 92 are parallel to each other when the spring 43 is at rest ( figure 1 ).

Pour maintenir le ressort 43, chaque jambage 71 présente une gorge 93 pour la patte 92 et, à l'opposé du tourillon 77, un doigt 94 sur lequel est enfilée la portion centrale 90.To maintain the spring 43, each leg 71 has a groove 93 for the lug 92 and, opposite the trunnion 77, a finger 94 on which is threaded the central portion 90.

Pour que le pêne 41 ne puisse pivoter au-delà de la position de repos, il est muni, ici au centre de la platine 70 à proximité de son extrémité opposée au cran 75, d'un ergot 95 dont la venue en appui sur la platine 31 fixe la position de repos (voir plus particulièrement la figure 2).So that the bolt 41 can not pivot beyond the rest position, it is provided, here in the center of the plate 70 near its end opposite the notch 75, a lug 95 whose coming abutting on the platinum 31 sets the rest position (see more particularly the figure 2 ).

Ainsi, la platine 31 joue le rôle d'une butée de fin de course contre laquelle est appliqué le pêne 41 en l'absence de sollicitation externe (position de repos).Thus, the plate 31 acts as a limit stop against which is applied the bolt 41 in the absence of external stress (rest position).

De même, le redan 59 joue le rôle d'une butée de fin de course contre laquelle est appliquée la poignée 40 en l'absence de sollicitation externe (position de repos correspondant à la position rabattue).Similarly, the redan 59 plays the role of an end stop against which is applied the handle 40 in the absence of external stress (rest position corresponding to the folded position).

Lorsque la porte 12 est ouverte (configuration illustrée sur la figure 2), aucune sollicitation externe ne s'applique sur la poignée 40 et sur le pêne 41, lesquels sont alors tous deux en position de repos.When the door 12 is open (configuration illustrated on the figure 2 ), no external stress applies to the handle 40 and the bolt 41, which are then both in the rest position.

On observera que la surface d'appui 78 du pêne 41 est alors à l'écart de la surface d'appui 79 de la poignée 40, de sorte qu'en configuration porte ouverte, il n'existe aucune transmission d'effort entre le pêne 41 et la poignée 40.It will be observed that the bearing surface 78 of the bolt 41 is then away from the bearing surface 79 of the handle 40, so that in open door configuration, there is no transmission of effort between the bolt 41 and the handle 40.

Lorsque la porte 12 est fermée (configuration illustrée sur les figures 3 et 5 à 8), la poignée 40 est, tout comme lorsque la porte est ouverte, en position de repos ou rabattue tandis que le pêne 41 est dans une position de verrouillage où il est engagé à accrochage avec les dents 76 dont est munie la portion dormante 11.When the door 12 is closed (configuration illustrated on the figures 3 and 5 to 8 ), the handle 40 is, as when the door is open, in the rest position or folded while the bolt 41 is in a locking position where it is engaged to hook with the teeth 76 which is provided with the dormant portion 11.

Chaque dent 76 saille de la paroi du rebord interne 17 formant l'un des versants de la gouttière 19, laquelle reçoit la platine 70 lorsque la porte 12 est fermée.Each tooth 76 protrudes from the wall of the inner rim 17 forming one of the slopes of the channel 19, which receives the plate 70 when the door 12 is closed.

Comme on le voit sur la figure 2, chaque dent 76 présente une rampe 96 et une face de retenue 97 en retrait par rapport à la rampe 96.As we see on the figure 2 each tooth 76 has a ramp 96 and a retaining face 97 set back from the ramp 96.

Le cran 75 du pêne 41 présente une rampe 98 et une face de retenue 99 en retrait par rapport à la rampe 98.The notch 75 of the bolt 41 has a ramp 98 and a retaining face 99 set back from the ramp 98.

Ici, la rampe 98 présente une portion inclinée et une portion droite. La portion inclinée s'étend de l'extrémité que l'on voit en bas sur les dessins (extrémité distale du pêne 41) à la portion droite. La portion droite s'étend de la portion inclinée à la face de retenue 99.Here, the ramp 98 has an inclined portion and a straight portion. The inclined portion extends from the end which is seen below in the drawings (distal end of the bolt 41) to the right portion. The straight portion extends from the inclined portion to the retaining face 99.

Lorsque l'on ferme la porte (passage de la configuration porte ouverte illustrée sur la figure 2 à la configuration porte fermée illustrée sur les figures 3 et 5 à 8), la rampe 98 vient au contact de la rampe 96, ce qui a pour effet d'entraîner le pêne 41 à l'encontre des ressorts 43 (sens de rotation où l'ergot 95 s'éloigne de la platine 31), vers une position de franchissement des dents 76, où l'arête entre la rampe 98 et la face de retenue 99 (cran 75) est au niveau de l'arête entre la rampe 96 et la face de retenue 97 (dents 76).When closing the door (passage of the open door configuration shown on the figure 2 to the closed door configuration illustrated on the figures 3 and 5 to 8 ), the ramp 98 comes into contact with the ramp 96, which has the effect of driving the bolt 41 against the springs 43 (direction of rotation where the lug 95 away from the plate 31), to a crossing position of the teeth 76, where the edge between the ramp 98 and the retaining face 99 (notch 75) is at the edge between the ramp 96 and the retaining face 97 (teeth 76).

Au-delà de la position de franchissement, c'est-à-dire lorsque la rampe 99 du cran 75 est au-delà des rampes 96 des dents 76, le pêne 41 est entraîné en sens inverse par les ressorts de rappel 43 et la face de retenue 99 du cran 75 vient en regard des faces de retenue 97 des dents 76, le mouvement se poursuivant jusqu'à la position de verrouillage où les dents 76 sont engagées à accrochage avec le cran 75 du pêne 41, ainsi qu'on le voit plus particulièrement sur la figure 6.Beyond the crossing position, that is to say when the ramp 99 of the notch 75 is beyond the ramps 96 of the teeth 76, the bolt 41 is driven in the opposite direction by the return springs 43 and the retaining face 99 of the notch 75 comes opposite the retaining faces 97 of the teeth 76, the movement continuing to the locking position where the teeth 76 are engaged to hook with the notch 75 of the bolt 41, as well as sees it more particularly on the figure 6 .

Au cours du passage entre la configuration porte ouverte (figure 2) et la configuration porte fermée (figures 3 et 5 à 8), la poignée 40 est restée dans la position de repos (position rabattue).During the passage between the open door configuration ( figure 2 ) and the closed door configuration ( figures 3 and 5 to 8 ), the handle 40 has remained in the rest position (folded position).

Comme expliqué ci-dessus, pour ouvrir la porte 12, l'utilisateur fait passer la poignée 40 de la position rabattue (position de repos) à la position relevée illustrée sur les figures 4, 9 et 10 (position de déverrouillage).As explained above, to open the door 12, the user moves the handle 40 from the folded position (rest position) to the raised position illustrated on the figures 4 , 9 and 10 (unlock position).

Lorsque la poignée 40 passe de sa position de repos à sa position de déverrouillage, le pêne 41 reste dans la position de verrouillage tant que la surface d'appui 79 de la poignée 40 n'est pas venue au contact de la surface d'appui 78 du pêne 41. Lorsque le contact est établi, le pêne 41 est entraîné par la poignée 40 à l'encontre des ressorts 43.When the handle 40 moves from its rest position to its unlocked position, the bolt 41 remains in the locking position as long as the bearing surface 79 of the handle 40 has not come into contact with the bearing surface. 78 of the bolt 41. When the contact is established, the bolt 41 is driven by the handle 40 against the springs 43.

Lorsque la poignée 40 est en position de déverrouillage (position relevée, fixée par l'application de l'ergot 56 contre la platine 31), le pêne 41 est lui aussi dans une position de déverrouillage, où il est dégagé des dents 76, de sorte que la porte 12 peut être ouverte.When the handle 40 is in the unlocked position (raised position, fixed by the application of the lug 56 against the plate 31), the bolt 41 is also in an unlocked position, where it is cleared teeth 76, so that the door 12 can be opened.

Lorsque l'utilisateur relâche la poignée 40, le ressort 42 ramène la poignée 40 dans sa position de repos (position rabattue) tandis que les ressorts 43 ramènent le pêne 41 vers sa position de repos.When the user releases the handle 40, the spring 42 returns the handle 40 to its rest position (folded position) while the springs 43 return the bolt 41 to its rest position.

Le mécanisme 13 est ainsi ramené automatiquement dans la configuration porte ouverte (figure 2).The mechanism 13 is thus brought automatically back into the open door configuration ( figure 2 ).

L'opercule 47 de la poignée 40 ferme un logement 100 (figure 5) prévu pour accueillir le barillet d'une serrure (non représentée) permettant de verrouiller la poignée 40 en position de repos. La poignée 40 ne pouvant quitter la position de repos, elle ne peut agir sur le pêne 41, de sorte que dans la configuration porte fermée, le pêne 41 ne peut être entraîné par la poignée 40 vers la position de déverrouillage.The cover 47 of the handle 40 closes a housing 100 ( figure 5 ) designed to receive the barrel of a lock (not shown) for locking the handle 40 in the rest position. The handle 40 can not leave the rest position, it can not act on the bolt 41, so that in the closed door configuration, the bolt 41 can be driven by the handle 40 to the unlocked position.

Bien entendu, lorsque l'on installe la serrure, on enlève l'opercule 47.Of course, when the lock is installed, the lid 47 is removed.

Dans des variantes non représentées, il est prévu une seule dent telle que 76 ou alors davantage que deux dents telles que 76 ; il est prévu un seul ressort tel que 43 ou alors davantage que deux ressorts tels que 43 ; et/ou il est prévu plusieurs ressorts tels que 42.In variants not shown, there is provided a single tooth such as 76 or more than two teeth such as 76; there is provided a single spring such as 43 or more than two springs such as 43; and / or there are provided several springs such as 42.

Dans d'autres variantes non représentées, l'on met en oeuvre un ou plusieurs organes de retenue différents des dents 76 et/ou des moyens de rappel élastiques différents des ressorts 42 et 43.In other variants not shown, it implements one or more different retaining members of the teeth 76 and / or elastic return means different from the springs 42 and 43.

Dans d'autres variantes non représentées, la poignée telle que 40 est montée différemment, par exemple en étant mobile à translation plutôt qu'à pivotement ; les pattes d'appui telles que 72 sont prévues sur la poignée telle que 40 plutôt que sur le pêne tel que 41 ou à la fois sur la poignée et le pêne ; il n'y a qu'une seule patte d'appui ou davantage que deux ; et/ou le pêne est conformé différemment, en étant par exemple moins long que la poignée 40 ou la platine 31.In other variants not shown, the handle such as 40 is mounted differently, for example by being movable in translation rather than pivoting; the support legs such as 72 are provided on the handle such as 40 rather than the bolt such as 41 or both on the handle and the bolt; he there is only one support leg or more than two; and / or the bolt is shaped differently, being for example shorter than the handle 40 or the plate 31.

Dans d'autres variantes non représentées, le dispositif auquel appartient la porte 12 est d'un type différent, par exemple un coffret prévu pour une seule rangée d'appareils électriques modulaires ou alors pour davantage que deux rangées, est d'un autre type d'enveloppe électrique qu'un coffret, par exemple une armoire, voire est un dispositif différent d'une enveloppe électrique, par exemple une armoire à pharmacie.In other variants not shown, the device to which belongs the door 12 is of a different type, for example a box provided for a single row of modular electrical appliances or for more than two rows, is of another type electric enclosure that a cabinet, for example a cabinet, or is a device different from an electrical envelope, for example a medicine cabinet.

De nombreuses autres variantes sont possibles en fonction des circonstances, et l'on rappelle à cet égard que l'invention ne se limite pas aux exemples décrits et représentés.Many other variants are possible depending on the circumstances, and it is recalled in this regard that the invention is not limited to the examples described and shown.
