Description

La présente invention concerne un dispositif d'ouverture et de fermeture pour une porte d'enveloppe telle qu'un coffret ou une armoire, par exemple destinée à loger des appareils électriques à basse tension, la porte étant applicable au moyen d'un joint d'étanchéité sur un bord fixe profilé de l'enveloppe.The present invention relates to an opening and closing device for an envelope door such as a box or a cabinet, for example intended to house low-voltage electrical devices, the door being applicable by means of a gasket. sealing on a fixed profiled edge of the envelope.

Le brevet EP-76 711 décrit un dispositif d'ouverture et de fermeture comprenant :

  • un corps fixé à la porte et logeant une pièce de manoeuvre solidaire en rotation d'un pêne susceptible de coopérer par un épaulement avec une aile de retenue associée au bord profilé,
  • le pêne pouvant tourner autour d'un axe perpendiculaire au plan de la porte et présentant une came inclinée par rapport à cet axe pour transformer la réaction du bord profilé en couple de rotation du pêne à l'encontre d'un couple de rappel antagoniste.
Patent EP-76,711 describes an opening and closing device comprising:
  • a body fixed to the door and housing a maneuvering piece integral in rotation with a bolt capable of cooperating by a shoulder with a retaining wing associated with the profiled edge,
  • the bolt being able to rotate about an axis perpendicular to the plane of the door and having a cam inclined with respect to this axis to transform the reaction of the profiled edge into a torque of rotation of the bolt against an antagonistic return torque.

Le pêne peut coopérer avec le bord profilé grâce à une pièce fixe rapportée au bord profilé et munie de deux zones d'appui raccordées par une rampe. Cette disposition engendre une prise d'appui graduée du pêne et a pour but d'empêcher la réouverture de l'armoire même si l'utilisateur n'exerce pas un effort suffisant pour obtenir une fermeture complète. Dans ce cas, la porte s'arrête dans une position de fermeture intermédiaire.The bolt can cooperate with the profiled edge thanks to a fixed part attached to the profiled edge and provided with two support zones connected by a ramp. This arrangement generates a graduated support catch for the bolt and is intended to prevent the reopening of the cabinet even if the user does not exert sufficient effort to obtain complete closure. In this case, the door stops in an intermediate closing position.

D'autre part, lorsque le bord profilé ne possède pas de pièce à prise d'appui graduée, il a été constaté que le frottement du pêne sur le bord profilé, au cours de sa rotation sous l'effet du couple de rappel, est parfois suffisant pour arrêter la porte avant que celle-ci n'atteigne la position définitive de fermeture.On the other hand, when the profiled edge does not have a part with a graduated support grip, it has been observed that the friction of the bolt on the profiled edge, during its rotation under the effect of the restoring torque, is sometimes sufficient to stop the door before it reaches the final closed position.

L'invention a pour but d'assurer à l'aide de moyens simples, dans un dispositif d'ouverture et de fermeture du type précédemment décrit, que le pêne ne s'arrête pas dans une position instable et que la porte vient dans sa position de fermeture définitive.The object of the invention is to ensure, using simple means, in an opening and closing device of the type described above, that the bolt does not stop in an unstable position and that the door comes into its final closed position.

Selon l'invention, l'épaulement du pêne rotatif coopère avec une rampe qui est associée à l'aile de retenue et dont l'orientation détermine à la fermeture une décroissance de la compression du joint depuis une position d'enclenchement du pêne sur la rampe jusqu'à une position de fermeture définitive. Il en résulte que le pêne rotatif ne s'arrête pas dans une position intermédiaire instable et vient occuper une position définitive stable.According to the invention, the shoulder of the rotary bolt cooperates with a ramp which is associated with the retaining wing and whose orientation determines on closing a decrease in the compression of the seal from a position of engagement of the bolt on the ramps to a final closed position. As a result, the rotary bolt does not stop in an unstable intermediate position and comes to occupy a stable final position.

La surface de glissement du bord profilé peut être perpendiculaire au plan de la porte quand celle-ci est en position fermée, la rampe s'étendant sur la tranche d'un élément de paroi mince situé sensiblement dans le prolongement de la surface de glissement. L'aile de retenue peut être parallèle au plan de la porte fermée, la rampe étant prévue sur le bord d'une pièce plate d'appui pour le péne, cette pièce étant apposée à l'aile de retenue.The sliding surface of the profiled edge may be perpendicular to the plane of the door when the latter is in the closed position, the ramp extending over the edge of a thin wall element situated substantially in the extension of the sliding surface. The wing of restraint can be parallel to the plane of the closed door, the ramp being provided on the edge of a flat support piece for the bolt, this piece being affixed to the retaining wing.

Les avantages et caractéristiques de l'invention seront mieux compris à l'aide de la description faite ci-après en regard des figures.The advantages and characteristics of the invention will be better understood with the aid of the description given below with reference to the figures.

La figure 9 illustre en vue de dessus une variante de la pièce de rampe.Figure 9 illustrates a top view of a variant of the ramp part.

Le dispositif d'ouverture et de fermeture représenté est associé à une enveloppe 10 telle qu'un coffret ou une armoire pour appareils électriques à basse tension. Il comprend un corps de serrure 20 monté traversant dans un orifice 11 ménagé dans une porte 12 de l'enveloppe, l'orifice ayant un axe X-X' perpendiculaire au plan P-P' de la porte. Un rebord 13 de la porte vient recouvrir en position fermée un bord 14 d'une partie fixe 15 de l'enveloppe. La porte 12 pivote autour d'un axe non représenté, perpendiculaire au plan des figures 1 à 7, et comprend un joint d'étanchéité 16 comprimé à l'état fermé. Le joint s'étend sur le pourtour de la porte près de son rebord 13.The opening and closing device shown is associated with an envelope 10 such as a box or a cabinet for low-voltage electrical devices. It comprises a lock body 20 mounted through through an orifice 11 formed in a door 12 of the envelope, the orifice having an axis X-X 'perpendicular to the plane P-P' of the door. A rim 13 of the door covers in closed position an edge 14 of a fixed part 15 of the envelope. The door 12 pivots about an axis not shown, perpendicular to the plane of Figures 1 to 7, and comprises a seal 16 compressed in the closed state. The seal extends around the perimeter of the door near its edge 13.

Les volumes intérieur et extérieur à l'enveloppe sont respectivement référencés 17 et 18 sur les figures.The interior and exterior volumes of the envelope are respectively referenced 17 and 18 in the figures.

Dans le corps 20 est montée rotative autour de X-X' une pièce de commande 21 manoeuvrable de l'extérieur de l'enveloppe au moyen d'un outil ou d'une clé. La pièce de commande est solidaire d'un pêne 22 sollicité par un ressort de torsion 23. Le pêne 22 présente une came 24 inclinée et décalée par rapport à l'axe X-X' de manière qu'en s'appliquant sur le bord fixe 14 de l'enveloppe quand la porte se ferme selon la flèche F1 elle transforme l'effort de réaction en couple de rotation du pêne (flèche F2, figure 2) à l'encontre du couple de rappel produit par le ressort 23 (flèche F3, figures 3 et 4). A la came 24 se raccorde un épaulement arrière 25, avantageusement constitué par une surface plane et prévu pour prendre appui derrière une surface plane de retenue propre à la partie fixe 15 de l'enveloppe. Le bord profilé 14 présente une extrémité 14a qui coopère avec le joint 16 pour assurer l'étanchéité souhaitée et participer au glissement du pêne 22, une aile 14b perpendiculaire au plan P de la porte et une aile de retenue 14c parallèle au plan P dans la position de fermeture.In the body 20 is rotatably mounted around XX ′ a control part 21 which can be operated from the outside of the envelope by means of a tool or a key. The control part is integral with a bolt 22 biased by a torsion spring 23. The bolt 22 has a cam 24 inclined and offset with respect to the axis XX 'so that when it is applied to the fixed edge 14 of the envelope when the door closes according to arrow F1 it transforms the reaction force into a torque of rotation of the bolt (arrow F2, FIG. 2) against the return torque produced by the spring 23 (arrow F3, Figures 3 and 4). To the cam 24 is connected a rear shoulder 25, advantageously constituted by a surface flat and designed to bear behind a flat retaining surface specific to the fixed part 15 of the envelope. The profiled edge 14 has an end 14a which cooperates with the seal 16 to ensure the desired seal and participate in the sliding of the bolt 22, a wing 14b perpendicular to the plane P of the door and a retaining wing 14c parallel to the plane P in the closed position.

A l'aile de retenue est associée selon l'invention une rampe 30 qui est parallèle à la longueur du bord 14 et du joint 16 et qui relie une zone 34 de prise d'appui et d'enclenchement du pêne à une zone 35 de fermeture définitive par une zone intermédiaire inclinée 36, la zone 34 étant située plus à l'intérieur de l'armoire que la zone 35. Au cours de la fermeture de la porte, l'épaulement 25 prend appui par son extrémité 25a sur la zone 34, puis décrit la rampe 30 sous l'effet du ressort de torsion jusqu'à la zone 35. Le joint d'étanchéité d'épaisseur nominale, comprimé dès qu'il rencontre l'extrémité 14a du bord profilé, est immédiatement comprimé à une épaisseur e₁ dans la position d'enclenchement (figure 6), puis revient progressivement à une épaisseur e₂ > e₁ dans la position de fermeture définitive (figure 7).According to the invention, a ramp 30 is associated with the retaining wing, which is parallel to the length of the edge 14 and of the joint 16 and which connects a zone 34 for taking hold and engaging the bolt to a zone 35 for final closure by an inclined intermediate zone 36, the zone 34 being located more inside the cabinet than the zone 35. During the closing of the door, the shoulder 25 is supported by its end 25a on the zone 34, then describes the ramp 30 under the effect of the torsion spring up to zone 35. The seal of nominal thickness, compressed as soon as it meets the end 14a of the profiled edge, is immediately compressed to a thickness e₁ in the latching position (Figure 6), then gradually returns to a thickness e₂> e₁ in the final closed position (Figure 7).

La rampe 30 peut être située (figures 5 à 7) sur une cornière 37 vissée ou collée au bord profilé 14. Plus précisément, la rampe est alors localisée sur la tranche d'un élément de paroi mince 38 situé sensiblement dans le prolongement d'une aile 39 de la cornière qui est apposée à l'aile 14b et qui détermine la surface de glissement parallèle à l'axe X-X', tandis que l'autre aile 40 de la cornière est apposée à l'aile 14c et détermine la surface de retenue perpendiculaire à l'axe X-X'.The ramp 30 can be located (FIGS. 5 to 7) on an angle iron 37 screwed or glued to the profiled edge 14. More precisely, the ramp is then located on the edge of a thin wall element 38 situated substantially in the extension of one wing 39 of the angle iron which is affixed to the wing 14b and which determines the sliding surface parallel to the axis XX ′, while the other wing 40 of the angle iron is affixed to the wing 14c and determines the retaining surface perpendicular to the axis XX ′.

La rampe 30 peut aussi être située (figure 9) en salle 41 sur le bord d'une pièce plate 42 apposée à l'aile 14c par vissage ou collage, cette saillie étant dans le prolongement de l'aile 14b.The ramp 30 can also be located (FIG. 9) in room 41 on the edge of a flat piece 42 affixed to the wing 14c by screwing or gluing, this projection being in the extension of the wing 14b.

Le fonctionnement du dispositif décrit est le suivant.The operation of the device described is as follows.

L'utilisateur souhaitant fermer la porte fait pivoter celle-ci dans le sens défini par la flèche F1 (figure 1). La came 24, initialement dans la position indiquée figure 1, entre en contact avec l'extrémité 14a du bord profilé 14, puis avec la surface de glissement 14b; ce faisant, l'extrémité 14a du bord 14 imprime un couple de rotation selon la flèche F2 au pêne 22, de sorte que le pêne tourne tout en glissant sur cette extrémité (voir figure 2 et en tirets figure 8). Puis l'utilisateur pousse suffisamment la porte pour que le joint 16 appliqué sur l'extrémité 14a se comprime à l'épaisseur e1 (figure 6); l'épaulement 25 du pêne est alors libéré et, sous l'effet du ressort 23, peut commencer à tourner selon la flèche F3 (voir figures 3 et 8) et à glisser sur la rampe 30 pour descendre de la zone 34 à la zone 35. La porte est alors complètement fermée et le joint d'étanchéité est comprimé à l'épaisseur e₂ > e₁. La position de fermeture du pêne est stable ; il ne peut pas revenir dans sa position initiale sans un acte volontaire d'ouverture de l'utilisateur.The user wishing to close the door rotates it in the direction defined by the arrow F1 (Figure 1). The cam 24, initially in the position indicated in FIG. 1, comes into contact with the end 14a of the profiled edge 14, then with the sliding surface 14b; in doing so, the end 14a of the edge 14 prints a torque according to the arrow F2 to the bolt 22, so that the bolt rotates while sliding on this end (see FIG. 2 and in dashes FIG. 8). Then the user pushes the door enough so that the seal 16 applied to the end 14a is compressed to the thickness e1 (FIG. 6); the shoulder 25 of the bolt is then released and, under the effect of the spring 23, can start to rotate according to arrow F3 (see Figures 3 and 8) and slide on the ramp 30 to descend from zone 34 to zone 35. The door is then completely closed and the seal is compressed to the thickness e₂> e₁. The bolt closing position is stable; it cannot return to its initial position without a voluntary act of opening the user.

L'épaulement 25 peut présenter vers son extrémité 25a une partie inclinée parallèle à la partie 36 de la rampe, le reste de l'épaulement étant perpendiculaire à l'axe X-X'. Pour ouvrir la porte, l'utilisateur fait tourner la pièce de commande 21 en comprimant le joint pour permettre à l'épaulement de passer de la zone de fermeture 35 à la zone de déclenchement 34, puis il peut tirer sur la porte tandis que le pêne 24 glisse sur la surface de glissement 14b. La compression du joint s'effectue par exemple à l'aide d'une pression exercée sur la porte, mais cette pression n'est pas impérative.The shoulder 25 may have towards its end 25a an inclined part parallel to the part 36 of the ramp, the rest of the shoulder being perpendicular to the axis XX ′. To open the door, the user rotates the control piece 21 by compressing the seal to allow the shoulder to pass from the closing zone 35 to the triggering zone 34, then he can pull the door while the bolt 24 slides on the sliding surface 14b. The compression of the seal is carried out for example using a pressure exerted on the door, but this pressure is not imperative.

La pièce de commande 21 peut de plus présenter, à l'opposé du pêne 22 par rapport à l'axe X-X', un bras 50 relié par un tourillon 51 à une tringle de manoeuvre 52 parallèle au bord profilé 14 et au joint 16 (figure 8). La tringle est reliée à une autre pièce de commande 21' à bras 50' par un tourillon 51' et elle est commandée par un organe de commande centrale 53 disposé entre les pièces 21, 21', de préférence au milieu. L'organe de commande 53 est manoeuvrable par une poignée verrouillable et peut lui-même présenter un troisième pêne similaire aux deux autres. Les pênes coopèrent tous avec des rampes orientées selon l'invention, ce qui permet de repartir sur la longueur du joint 16 l'effort exercé sur celui-ci.The control piece 21 may also have, opposite the bolt 22 relative to the axis XX ', an arm 50 connected by a pin 51 to an operating rod 52 parallel to the profiled edge 14 and to the joint 16 (Figure 8). The rod is connected to another control part 21 'with arms 50' by a pin 51 'and it is controlled by a central control member 53 disposed between the parts 21, 21', preferably in the middle. The control member 53 is maneuverable by a lockable handle and may itself have a third bolt similar to the other two. The bolts all cooperate with ramps oriented according to the invention, which allows to spread over the length of the seal 16 the force exerted on it.
