Description

Le domaine de l'invention est celui de la conception et de la fabrication de bagages.The field of the invention is that of the design and manufacture of luggage.

Le domaine de l'invention est plus particulièrement celui des mécanismes d'ouverture et de fermeture intégrés dans des bagages.The field of the invention is more particularly that of opening and closing mechanisms integrated into luggage.

L'ouverture et la fermeture d'un ouvrant par rapport à un dormant sur lequel est monté mobile l'ouvrant peuvent être réalisées de manière purement manuelle telle que cela est traditionnel dans le domaine de la bagagerie, ou alors être réalisées de manière motorisée tel que cela peut être constaté dans d'autres domaines techniques.The opening and closing of an opening relative to a frame on which the opening is movably mounted can be carried out in a purely manual manner as is traditional in the field of luggage storage, or else be carried out in a motorized manner such as that this can be seen in other technical fields.

Pour une conception ou l'actionnement est uniquement manuel, l'ouvrant est classiquement couplé au dormant à l'aide d'une charnière.For a design where the operation is only manual, the sash is conventionally coupled to the frame using a hinge.

Dans ce cas, l'ouvrant est ouvert ou fermé en étant simplement pivoté autour d'un axe de pivotement formé par la charnière.In this case, the opening is opened or closed by simply being pivoted around a pivot axis formed by the hinge.

Selon une conception classique d'un mécanisme d'ouverture d'un bagage à actionnement manuel, le mécanisme n'exerce pas ou peu de résistance à l'encontre d'une manipulation de l'ouvrant par un utilisateur.According to a classic design of a manually operated luggage opening mechanism, the mechanism exerts little or no resistance against manipulation of the opening by a user.

Ainsi, un utilisateur peut aisément rabattre l'ouvrant sur le dormant, faisant passer de la sorte l'ouvrant d'une position ouverte à une position rabattue sur le dormant.Thus, a user can easily fold the sash onto the frame, thereby moving the sash from an open position to a folded position on the frame.

Les mécanismes avec un actionnement manuel sont généralement pourvus de moyens de verrouillage de l'ouvrant dans sa position rabattue sur le dormant.Manually operated mechanisms are generally provided with means for locking the sash in its folded position on the frame.

De tels moyens de verrouillage peuvent être constitués par :

  • une encoche présentée par l'ouvrant sur une de ses tranches ;
  • un cran présenté par le dormant et destiné à s'engager dans l'encoche dans la position rabattue de l'ouvrant ;
  • un actionneur couplé au cran pour permettre de le rétracter de l'encoche lors de l'ouverture de l'ouvrant.
Such locking means may consist of:
  • a notch presented by the opening on one of its edges;
  • a notch presented by the frame and intended to engage in the notch in the folded position of the opening;
  • an actuator coupled to the notch to allow it to be retracted from the notch when opening the sash.

Le cran peut présenter un biseau et des moyens de rappel dans une position en saillie. De cette manière, quand l'ouvrant est rabattu il exerce une pression sur le cran et le repousse, autorisant de la sorte le passage de l'ouvrant dans sa position rabattue. Arrivé dans sa position rabattue, l'encoche se retrouve en vis-à-vis du cran qui, sous l'effet des moyens de rappel, s'engage dans l'encoche et verrouille l'ouvrant dans sa position rabattue.The notch may have a bevel and return means in a projecting position. In this way, when the sash is folded down it exerts pressure on the notch and pushes it back, thereby allowing the sash to pass into its folded position. Arriving in its folded position, the notch finds itself opposite the notch which, under the effect of the return means, engages in the notch and locks the opening in its folded position.

S'agissant des mécanismes motorisés, l'emploi de moteurs électriques permet d'ouvrir et de fermer un ouvrant par rapport à un dormant sans nécessiter l'intervention d'une personne. Dans ce cas, il n'est alors pas nécessaire d'ouvrir ou de refermer manuellement l'ouvrant, le moteur étant apte à réaliser à lui seul l'ouverture ou la fermeture de l'ouvrant.Regarding motorized mechanisms, the use of electric motors makes it possible to open and close an opening in relation to a frame without requiring the intervention of a person. In this case, it is then not necessary to manually open or close the sash, the motor being able to carry out the opening or closing of the sash on its own.

EP 3 476 715 A1 divulgue un mécanisme d'ouverture/fermeture d'un ouvrant par rapport à un dormant, du type provoquant à l'ouverture une translation de l'ouvrant d'un plan de fermeture à un plan d'ouverture parallèle au plan de fermeture, suivie d'un pivotement de l'ouvrant autour d'un axe de pivotement orthogonal à la translation de l'ouvrant, et inversement à la fermeture, qui permette la motorisation des deux déplacements. EP 3 476 715 A1 discloses a mechanism for opening/closing an opening relative to a frame, of the type causing upon opening a translation of the opening from a closing plane to an opening plane parallel to the closing plane, followed a pivoting of the opening around a pivot axis orthogonal to the translation of the opening, and conversely to closing, which allows the motorization of the two movements.

Ces différents types de mécanismes présentent chacun leurs spécificités et leurs avantages intrinsèques. Le mécanisme purement manuel et mécanique permet une fermeture de l'ouvrant réalisable de manière naturelle et intuitive pour un utilisateur. Le mécanisme motorisé offre quant à lui une fermeture de l'ouvrant automatique ne nécessitant pas d'intervention directe de l'utilisateur.These different types of mechanisms each have their own specificities and intrinsic advantages. The purely manual and mechanical mechanism allows closing of the opening which can be achieved in a natural and intuitive manner for a user. The motorized mechanism provides automatic closing of the sash, requiring no direct intervention from the user.

Il peut être ainsi recherché à concilier les avantages d'un mécanisme d'ouverture classique avec un actionnement manuel à ceux d'un mécanisme motorisé.It may thus be sought to reconcile the advantages of a conventional opening mechanism with manual operation with those of a motorized mechanism.

C'est précisément l'objectif de l'invention de proposer un bagage disposant d'un dispositif d'ouverture et de fermeture de l'ouvrant qui concilie l'intuitivité de la fermeture d'un mécanisme d'ouverture manuel, à la capacité de fermeture automatique produite par un moteur.It is precisely the objective of the invention to propose luggage having a device for opening and closing the opening which combines the intuitiveness of closing a manual opening mechanism, with the capacity automatic closing produced by a motor.

L'invention a également pour objectif de fournir un tel bagage qui permette de déclencher un verrouillage automatique lors du passage d'un ouvrant dans une position rabattue sur son dormant.The invention also aims to provide such luggage which makes it possible to trigger automatic locking when an opening is placed in a folded position on its frame.

Ces objectifs, ainsi que d'autres qui apparaîtront par la suite, sont atteints grâce à l'invention qui a pour objet un bagage comprenant :

  • un caisson formant un dormant ;
  • un couvercle formant un ouvrant mobile par rapport au dormant entre une position fermée dans laquelle il est rabattu sur le dormant, et au moins une position ouverte ;
  • au moins un moteur électrique motorisant l'ouverture et la fermeture de l'ouvrant ; caractérisé en ce qu'il comprend :
  • des moyens de détermination d'une force exercée E sur l'ouvrant et/ou une vitesse de déplacement D de l'ouvrant lors de l'application d'un effort par un utilisateur entraînant un déplacement de l'ouvrant depuis l'une de ses positions ouvertes en direction de sa position fermée ;
  • une unité électronique paramétrée avec une force seuil S et/ou une vitesse seuil V ;
et en ce que l'unité électronique est en outre paramétrée pour piloter le moteur électrique pour qu'il entraîne l'ouvrant en position fermée si la force exercée E est supérieure ou égale à la force seuil S, ou si la vitesse de déplacement D est supérieure ou égale à la vitesse seuil V.These objectives, as well as others which will appear subsequently, are achieved thanks to the invention which relates to luggage comprising:
  • a box forming a frame;
  • a cover forming a movable opening relative to the frame between a closed position in which it is folded onto the frame, and at least one open position;
  • at least one electric motor powering the opening and closing of the sash; characterized in that it includes:
  • means for determining a force exerted E on the opening and/or a speed of movement D of the opening during the application of a force by a user causing a movement of the opening from one of its open positions towards its closed position;
  • an electronic unit configured with a threshold force S and/or a threshold speed V;
and in that the electronic unit is further configured to control the electric motor so that it drives the opening in the closed position if the force exerted E is greater than or equal to the threshold force S, or if the movement speed D is greater than or equal to the threshold speed V.

Grâce au bagage selon l'invention, un utilisateur peut déclencher une fermeture automatique du couvercle en initiant manuellement cette fermeture.Thanks to the luggage according to the invention, a user can trigger automatic closing of the lid by manually initiating this closing.

Cet utilisateur n'a en effet pas de besoin d'accompagner complètement la fermeture du couvercle grâce au moteur électrique qui prend le relai du mouvement initié manuellement.This user does not in fact need to completely accompany the closing of the lid thanks to the electric motor which takes over from the movement initiated manually.

De ce fait, la fermeture automatique par le biais du moteur est initiée de manière particulièrement intuitive.As a result, automatic closing via the motor is initiated in a particularly intuitive manner.

Cette fermeture automatique est plus précisément réalisée dès que l'utilisateur exerce un effort suffisant sur le couvercle. L'effort est détecté grâce aux moyens de détermination qui permettent d'obtenir la force exercée ou la vitesse de déplacement de l'ouvrant résultants de l'action de l'utilisateur. La force exercée ou la vitesse de déplacement sont ensuite comparées à la force seuil ou la vitesse seuil pour permettre le déclenchement du pilotage du moteur électrique par l'unité électronique dans le cas où la force exercée E ou la vitesse de déplacement D a atteint ou dépassé à la force seuil S ou la vitesse seuil S.This automatic closing is more precisely carried out as soon as the user exerts sufficient force on the cover. The effort is detected using the determination means which make it possible to obtain the force exerted or the speed of movement of the opening resulting from the action of the user. The force exerted or the speed of movement are then compared to the threshold force or the threshold speed to enable the activation of the control of the electric motor by the electronic unit in the case where the force exerted E or the speed of movement D has reached or exceeded at the threshold force S or the threshold speed S.

Cette fermeture automatique par le moteur électrique permet également d'assurer le bon passage en position fermée de l'ouvrant.This automatic closing by the electric motor also ensures the correct passage into the closed position of the opening.

Avec un bagage selon l'art antérieur disposant d'un mécanisme classique à actionnement manuel, un utilisateur peut initier la fermeture du couvercle et le laisse retomber sur le caisson du bagage. Cette cinématique permet de verrouiller le couvercle dans une position fermée. Toutefois il peut être constaté certaines situations dans laquelle le couvercle n'arrive pas à atteindre sa position fermée et verrouillée, par exemple si l'inertie conférée au couvercle lors de l'initiation de la fermeture n'est pas suffisante.With luggage according to the prior art having a conventional manual actuation mechanism, a user can initiate the closing of the cover and lets it fall onto the luggage compartment. This kinematic allows the lid to be locked in a closed position. However, certain situations may be observed in which the cover cannot reach its closed and locked position, for example if the inertia given to the cover when initiating closing is not sufficient.

De plus, la retombée du couvercle sur le caisson peut être brutale, au risque de dégrader progressivement le bagage.In addition, the lid falling back onto the box can be abrupt, with the risk of gradually damaging the luggage.

La fermeture automatique du couvercle du bagage selon l'invention évite ces situations. Ainsi, lorsqu'un utilisateur initie manuellement la fermeture, cette dernière est terminée de manière certaine et contrôlée (non brutale) par le moteur électrique, et l'utilisateur peut se saisir du bagage et le déplacer sans risque d'ouverture inopinée.The automatic closing of the luggage cover according to the invention avoids these situations. Thus, when a user manually initiates the closing, the latter is completed in a certain and controlled manner (not suddenly) by the electric motor, and the user can grab the luggage and move it without risk of unexpected opening.

Avantageusement, le bagage comprend une charnière entre l'ouvrant et le dormant, le moteur électrique coopérant avec la charnière pour ouvrir ou fermer l'ouvrant, et les moyens de détermination comprennent un premier capteur de position d'un organe de la charnière, dit « organe témoin », les moyens de détermination étant paramétrés pour calculer la force exercée E à partir d'un déplacement de l'organe témoin engendré par l'application de l'effort sur l'ouvrant ainsi que d'une résistance à ce déplacement exercée par le moteur électrique, et/ou calculer la vitesse de déplacement de l'ouvrant à partir d'un déplacement de l'organe témoin engendré par l'application de l'effort sur l'ouvrant.Advantageously, the luggage comprises a hinge between the opening and the frame, the electric motor cooperating with the hinge to open or close the opening, and the determination means comprise a first position sensor of a hinge member, called “control member”, the determination means being configured to calculate the force exerted E from a movement of the control body generated by the application of the force on the opening as well as a resistance to this movement exerted by the electric motor, and/or calculate the speed of movement of the opening from a movement of the indicator member generated by the application of the force on the opening.

De cette manière, la détection de la force exercée sur l'ouvrant, et/ou de la vitesse de cet ouvrant est réalisée par le biais d'un organe de la charnière. Cette détermination est réalisée de manière indirecte.In this way, the detection of the force exerted on the opening, and/or the speed of this opening is carried out by means of a hinge member. This determination is made indirectly.

De plus, en étant situé sur cette charnière, la position de l'organe témoin permet de déterminer la position de l'ouvrant par rapport au dormant, ainsi que les évolutions de position de l'ouvrant par rapport au dormant grâce aux évolutions de la position de cet organe témoin.In addition, by being located on this hinge, the position of the indicator member makes it possible to determine the position of the opening relative to the frame, as well as changes in the position of the opening relative to the frame thanks to changes in the position of this witness body.

Dans ce cas, selon une conception préférentielle, la charnière comprend :

  • un mécanisme de conversion d'un mouvement de rotation du moteur électrique en un mouvement de translation, le mécanisme de conversion comprenant un organe de transmission mobile en translation le long d'un axe de translation T ;
  • un organe de couplage couplé par une première de ses extrémités à l'ouvrant sur un premier point de pivot excentré d'un axe de rotation de l'ouvrant, et à une seconde de ses extrémités à l'organe de transmission sur un second point de pivot, une translation de l'organe de transmission selon un premier sens entraînant une ouverture de l'ouvrant, et une translation de l'organe de transmission selon un second sens entraînant une fermeture de l'ouvrant ;
l'organe de transmission formant l'organe témoin.In this case, according to a preferred design, the hinge comprises:
  • a mechanism for converting a rotational movement of the electric motor into a translational movement, the conversion mechanism comprising a transmission member movable in translation along a translation axis T;
  • a coupling member coupled by a first of its ends to the opening on a first pivot point eccentric to an axis of rotation of the opening, and at a second of its ends to the transmission member on a second point pivot, a translation of the transmission member in a first direction causing an opening of the opening, and a translation of the transmission member in a second direction causing a closing of the opening;
the transmission member forming the witness member.

Cette conception de la charnière permet que l'organe témoin soit formé par un organe du mécanisme de conversion permettant de transmettre le mouvement produit par le moteur électrique jusqu'à l'ouvrant.This design of the hinge allows the indicator member to be formed by a member of the conversion mechanism making it possible to transmit the movement produced by the electric motor to the opening.

En conséquence, c'est de manière sûre et certaine que le déplacement de l'organe témoin peut être corrélé à un déplacement de l'ouvrant.Consequently, it is in a safe and certain manner that the movement of the witness member can be correlated to a movement of the opening.

Selon une caractéristique préférentielle, l'ouvrant est :

  • mobile par rapport au dormant entre une position d'ouverture maximale et une position d'ouverture intermédiaire dans laquelle l'ouvrant est directement positionné à proximité de sa position fermée et fait saillie par rapport au dormant ;
  • mobile par rapport au dormant entre la position d'ouverture intermédiaire et la position fermée ;
et l'unité électronique est en outre paramétrée pour piloter le moteur électrique pour qu'il tende à maintenir l'ouvrant dans sa position d'ouverture intermédiaire en exerçant une résistance R allant à l'encontre d'une translation de l'ouvrant dans sa position d'ouverture intermédiaire à sa position fermée, avec la résistance R égale à la force seuil S.According to a preferred characteristic, the opening is:
  • movable relative to the frame between a maximum opening position and an intermediate opening position in which the opening is directly positioned near its closed position and projects relative to the frame;
  • movable relative to the frame between the intermediate open position and the closed position;
and the electronic unit is further configured to control the electric motor so that it tends to maintain the opening in its intermediate opening position by exerting a resistance R going against a translation of the opening in its intermediate opening position to its closed position, with the resistance R equal to the threshold force S.

Selon ce mode de réalisation, l'ouvrant présente une position proche de sa position fermée, qu'il tend à maintenir.According to this embodiment, the opening has a position close to its closed position, which it tends to maintain.

Une telle position d'ouverture intermédiaire peut permettre, par exemple, d'éviter que l'ouvrant n'adopte une position dans laquelle il peut être très difficilement préhensible par un utilisateur, par exemple pour interrompre sa fermeture ou pour le rouvrir.Such an intermediate opening position can make it possible, for example, to prevent the opening from adopting a position in which it can be very difficult for a user to grasp, for example to interrupt its closing or to reopen it.

Cette position d'ouverture intermédiaire peut également procurer au bagage une cinématique d'ouverture relativement sophistiquée et susceptible de procurer un aspect qualitatif au bagage.This intermediate opening position can also provide the luggage with relatively sophisticated opening kinematics and capable of providing a qualitative appearance to the luggage.

Dans sa position d'ouverture intermédiaire, ce n'est que lors de l'application d'un effort supérieur ou égal à la résistance exercée par le moteur électrique (et ainsi équivalente à la force seuil), que l'ouvrant va pouvoir passer dans sa position fermée sous l'action du moteur électrique.In its intermediate opening position, it is only when applying a force greater than or equal to the resistance exerted by the electric motor (and thus equivalent to the threshold force), that the sash will be able to pass in its closed position under the action of the electric motor.

Avantageusement, l'ouvrant est :

  • mobile en rotation par rapport au dormant entre la position d'ouverture maximale et la position d'ouverture intermédiaire ;
  • mobile en translation par rapport au dormant entre la position d'ouverture intermédiaire et la position fermée.
Advantageously, the opening is:
  • movable in rotation relative to the frame between the maximum opening position and the intermediate opening position;
  • movable in translation relative to the frame between the intermediate opening position and the closed position.

L'ouvrant présente alors une cinématique d'ouverture qualitative et/ou attractive.The opening then presents a qualitative and/or attractive opening kinematics.

Dans ce cas, selon une caractéristique préférée, la charnière comprend au moins un bâti mobile monté mobile en translation sur au moins un élément de guidage en translation présenté par le dormant, et l'ouvrant est monté au moins mobile en rotation sur le ou les bâtis mobiles.In this case, according to a preferred characteristic, the hinge comprises at least one mobile frame mounted movable in translation on at least one guiding element in translation presented by the frame, and the opening is mounted at least movable in rotation on the one or more mobile frames.

Selon une conception avantageuse, le dormant présente un cadre délimitant un emplacement occupé par l'ouvrant dans sa position fermée, et les moyens de détermination comprennent au moins un second capteur de position de l'ouvrant par rapport au cadre, positionné à proximité immédiate du cadre, le ou les seconds capteurs de position étant indépendants du ou des premiers capteurs de position, les moyens de détermination étant paramétrés pour calculer la force exercée E à partir d'un signal du ou des seconds capteurs engendrés par l'application d'un effort sur l'ouvrant dans sa position d'ouverture intermédiaire à la force exercée.According to an advantageous design, the frame has a frame delimiting a location occupied by the opening in its closed position, and the determination means comprise at least a second position sensor of the opening relative to the frame, positioned in the immediate vicinity of the opening. frame, the second position sensor(s) being independent of the first position sensor(s), the determination means being configured to calculate the force exerted E from a signal from the second sensor(s) generated by the application of a force on the opening in its intermediate opening position to the force exerted.

Un second capteur, ou plusieurs seconds capteurs, permettent de s'assurer que l'effort appliqué sur l'ouvrant pour le fermer est complètement capté par les moyens de détermination.A second sensor, or several second sensors, ensure that the force applied to the opening to close it is completely captured by the determination means.

En effet, du fait que le premier capteur permet de déterminer la force exercée sur l'ouvrant de manière indirecte, l'intégration d'autres capteurs permet de s'assurer qu'une force exercée sur l'ouvrant est correctement déterminée.Indeed, because the first sensor makes it possible to determine the force exerted on the opening indirectly, the integration of other sensors makes it possible to ensure that a force exerted on the opening is correctly determined.

Dans ce cas, selon une conception préférée, le ou les seconds capteurs sont positionnés à proximité immédiate d'un bord avant du cadre, opposé à un bord arrière du cadre, la charnière étant positionnée dans le dormant du côté du bord arrière du cadre.In this case, according to a preferred design, the second sensor(s) are positioned in the immediate vicinity of a front edge of the frame, opposite a rear edge of the frame, the hinge being positioned in the frame on the side of the rear edge of the frame.

Cette conception permet de compenser le phénomène de levier et l'apparition d'un moment parasite dans le cas où une personne exerce une force sur une partie de l'ouvrant qui est opposée à la charnière.This design makes it possible to compensate for the lever phenomenon and the appearance of a parasitic moment in the case where a person exerts a force on a part of the opening which is opposite the hinge.

Plus précisément, dans le cas où une personne exerce un effort pour tendre à fermer l'ouvrant sur un bord avant opposé au bord arrière de l'ouvrant, alors cet effort produit un effet de levier sur la charnière et cet effort n'est pas correctement capté par le ou les premiers capteurs du fait de la présence d'un moment parasite au niveau de la charnière.More precisely, in the case where a person exerts an effort to tend to close the opening on a front edge opposite the rear edge of the opening, then this effort produces a leverage effect on the hinge and this effort is not correctly captured by the first sensor(s) due to the presence of a parasitic moment at the hinge.

Aussi, le positionnement d'un ou de plusieurs seconds capteurs à proximité immédiate du bord avant du cadre permet de compenser ce moment parasite et de s'assurer que l'effort appliqué sur l'ouvrant soit correctement déterminé.Also, the positioning of one or more second sensors in the immediate vicinity of the front edge of the frame makes it possible to compensate for this parasitic moment and to ensure that the force applied to the opening is correctly determined.

Au final, un effort de même intensité permet d'entraîner la fermeture automatique de l'ouvrant, que cet effort soit appliqué sur une partie ou une partie arrière de l'ouvrant.Ultimately, an effort of the same intensity makes it possible to cause the automatic closing of the opening, whether this effort is applied to a part or a rear part of the opening.

Selon une caractéristique préférée, le ou les seconds capteurs sont des capteurs à effet Hall, et l'ouvrant porte un ou des aimants positionnés en regard du ou des capteurs à effet Hall.According to a preferred characteristic, the second sensor(s) are Hall effect sensors, and the opening carries one or more magnets positioned opposite the Hall effect sensor(s).

De tels capteurs à effet Hall permettent de déterminer la position de l'ouvrant par rapport au cadre grâce à la capacité de ces capteurs à déterminer la position d'un objet par le biais des champs magnétiques.Such Hall effect sensors make it possible to determine the position of the opening relative to the frame thanks to the ability of these sensors to determine the position of an object through magnetic fields.

Un bagage selon l'invention est illustré par les figures 1 à 6.Luggage according to the invention is illustrated by the figures 1 to 6 .

Le bagage comprend un caisson 20 et un couvercle 10 monté mobile sur le caisson 20.The luggage comprises a box 20 and a cover 10 movably mounted on the box 20.

Le caisson 20 forme un dormant 2, et le couvercle forme un ouvrant 1.The box 20 forms a frame 2, and the cover forms an opening 1.

En d'autres termes, l'ouvrant 1 est monté mobile par rapport au dormant 2.In other words, the opening 1 is mounted movable relative to the frame 2.

En référence aux figures 1 à 6, l'ouvrant 1 est mobile entre une position fermée et au moins une position ouverte.With reference to figures 1 to 6 , the opening 1 is movable between a closed position and at least one open position.

Dans sa position fermée, l'ouvrant 1 est rabattu sur le dormant 2.In its closed position, the opening 1 is folded onto the frame 2.

Selon la figure 3, et tel que cela est détaillé par la suite, le dormant 2 présente un cadre 200. Ce cadre 200 délimite un emplacement qui est occupé par l'ouvrant 1 dans sa position fermée F.According to Figure 3 , and as detailed below, the frame 2 has a frame 200. This frame 200 delimits a location which is occupied by the opening 1 in its closed position F.

En référence au premier mode de réalisation illustré par les figures 1 et 2, l'ouvrant 1 est monté mobile en rotation uniquement sur le dormant 2.With reference to the first embodiment illustrated by the figures 1 And 2 , the opening 1 is mounted movable in rotation only on the frame 2.

En référence au deuxième mode de réalisation illustré par les figures 3 à 6, l'ouvrant 1 présente une cinématique d'ouverture ou de fermeture plus complexe par rapport au premier mode de réalisation.With reference to the second embodiment illustrated by the figures 3 to 6 , the opening 1 has more complex opening or closing kinematics compared to the first embodiment.

Plus précisément, l'ouvrant 1 est :

  • mobile en rotation par rapport au dormant (2) entre une position d'ouverture maximale et une position d'ouverture intermédiaire ;
  • mobile en translation par rapport au dormant 2 entre la position d'ouverture intermédiaire et la position fermée.
More precisely, opening 1 is:
  • movable in rotation relative to the frame (2) between a maximum opening position and an intermediate opening position;
  • movable in translation relative to the frame 2 between the intermediate open position and the closed position.

La position d'ouverture intermédiaire, illustrée par la figure 5, correspond notamment à une position dans laquelle l'ouvrant 1 est suffisamment écarté de sa position fermée, par le biais d'une translation, pour qu'il puisse être saisi par un utilisateur du bagage.The intermediate opening position, illustrated by the figure 5 , corresponds in particular to a position in which the opening 1 is sufficiently moved away from its closed position, by means of a translation, so that it can be grasped by a user of the luggage.

Bien entendu, le bagage selon le premier mode de réalisation peut également présenter un ouvrant 1 qui, tout en étant uniquement monté mobile en rotation, présente une position d'ouverture intermédiaire comparable à celle du deuxième mode de réalisation.Of course, the luggage according to the first embodiment can also have an opening 1 which, while only being mounted movable in rotation, has an intermediate opening position comparable to that of the second embodiment.

Pour permettre la mobilité de l'ouvrant 1 sur le dormant 2, le bagage comprend une charnière 3 entre l'ouvrant 1 et le dormant 2.To allow the mobility of the opening 1 on the frame 2, the luggage includes a hinge 3 between the opening 1 and the frame 2.

La charnière 3 est décrite plus précisément par la suite en référence aux deux modes de réalisation.The hinge 3 is described more precisely below with reference to the two embodiments.

Le bagage comprend également :

  • au moins un moteur électrique 40 ;
  • des moyens de détermination 5 d'une force exercée E sur l'ouvrant 1 et/ou une vitesse de déplacement D de l'ouvrant 1 lors de l'application d'un effort par un utilisateur entraînant un déplacement de l'ouvrant 1 depuis l'une de ses positions ouvertes en direction de sa position fermée ;
  • une unité électronique 6 couplée au moteur électrique 40 et aux moyens de détermination 5.
The baggage also includes:
  • at least one electric motor 40;
  • means 5 for determining a force exerted E on the opening 1 and/or a speed of movement D of the opening 1 during the application of a force by a user causing a movement of the opening 1 from one of its open positions towards its closed position;
  • an electronic unit 6 coupled to the electric motor 40 and to the determination means 5.

Le ou les moteurs électriques 40 motorisent l'ouverture et la fermeture de l'ouvrant 1. A cet effet, le ou les moteurs électriques 40 coopèrent avec la charnière 3.The electric motor(s) 40 motorize the opening and closing of the opening 1. For this purpose, the electric motor(s) 40 cooperate with the hinge 3.

Selon les présents modes de réalisation, le bagage comprend notamment deux moteurs électriques 40.According to the present embodiments, the luggage notably comprises two electric motors 40.

Ces moteurs électriques 40 sont des moteurs à courant continu à balais. Chaque moteur électrique 40 est en outre équipé d'un réducteur 41 et produit un mouvement de rotation.These electric motors 40 are brushed direct current motors. Each electric motor 40 is further equipped with a reduction gear 41 and produces a rotational movement.

La charnière comprend plus précisément deux sous-ensembles dont un sous-ensemble gauche et un sous-ensemble droit coopérant chacun avec l'un des deux moteurs électrique 40.The hinge more precisely comprises two sub-assemblies including a left sub-assembly and a right sub-assembly each cooperating with one of the two electric motors 40.

Bien entendu, il est envisageable que la charnière 3 comprenne deux sous-ensembles dont un seul coopère avec un unique moteur électrique 40.Of course, it is possible that the hinge 3 comprises two sub-assemblies, only one of which cooperates with a single electric motor 40.

Tel qu'expliqué précédemment, grâce aux moyens de détermination 5, il est possible d'obtenir la force exercée E sur l'ouvrant et/ou une vitesse de déplacement D de l'ouvrant 1.As explained previously, thanks to the determination means 5, it is possible to obtain the force exerted E on the opening and/or a movement speed D of the opening 1.

La force exercée E résulte d'un actionnement manuel par un utilisateur, soit en d'autres termes du saisissement de l'ouvrant 1 par une main M de l'utilisateur et l'application d'un effort pour fermer l'ouvrant 1.The force exerted E results from manual actuation by a user, or in other words from the grasping of the opening 1 by a hand M of the user and the application of an effort to close the opening 1.

Ces moyens de détermination 5 sont décrits plus en détails par la suite.These determination means 5 are described in more detail below.

De plus, selon l'invention, l'unité électronique 6 est paramétrée avec une force seuil S et/ou une vitesse seuil V.Furthermore, according to the invention, the electronic unit 6 is parameterized with a threshold force S and/or a threshold speed V.

Par exemple cette force seuil S peut être égale à 20N.For example, this threshold force S can be equal to 20N.

La force exercée E est ainsi utilisée par l'unité électronique 6 qui est paramétrée pour piloter le moteur électrique 40 pour qu'il entraîne l'ouvrant 1 en position fermée si la force exercée E est supérieure ou égale à la force seuil S.The force exerted E is thus used by the electronic unit 6 which is configured to control the electric motor 40 so that it drives the opening 1 in the closed position if the force exerted E is greater than or equal to the threshold force S.

Selon un autre exemple, la vitesse seuil V peut correspondre à une vitesse angulaire de rotation de l'ouvrant 1 déterminée expérimentalement pour correspondre à une vitesse suffisante pour permettre le passage de l'ouvrant 1 d'une position ouverte à sa position d'ouverture intermédiaire.According to another example, the threshold speed V can correspond to an angular speed of rotation of the opening 1 determined experimentally to correspond to a speed sufficient to allow the passage of the opening 1 from an open position to its opening position intermediate.

Dans ce cas, dès que la vitesse de déplacement D est supérieure ou égale à la vitesse seuil C, alors l'unité électronique 6 pilote le moteur électrique 40 pour qu'il entraîne, suite à l'arrivée de l'ouvrant 1 dans sa position d'ouverture intermédiaire, son passage de cette position d'ouverture intermédiaire à sa position fermée.In this case, as soon as the movement speed D is greater than or equal to the threshold speed C, then the electronic unit 6 controls the electric motor 40 so that it drives, following the arrival of the opening 1 in its intermediate opening position, its passage from this intermediate opening position to its closed position.

Le bagage comprend également des moyens d'arrêt du moteur électrique 40.The luggage also includes means for stopping the electric motor 40.

Ces moyens d'arrêt du moteur électrique 40 sont configurés pour interrompre une fermeture de l'ouvrant 1 par le moteur électrique 40 suite à la détection d'une résistance allant à l'encontre de la fermeture de l'ouvrant.These stopping means of the electric motor 40 are configured to interrupt a closing of the opening 1 by the electric motor 40 following the detection of a resistance going against the closing of the opening.

Tel que cela est détaillé par la suite, cette résistance est détectée à l'aide des moyens de détermination 5.As detailed below, this resistance is detected using the determination means 5.

Le ou les moteurs électriques 40 peuvent entraîner en mobilité l'ouvrant 1 sur le dormant 2 à l'aide de la conception décrite ci-après du couplage du ou des moteurs électriques 40 à la charnière 3.The electric motor(s) 40 can move the opening 1 on the frame 2 using the design described below of the coupling of the electric motor(s) 40 to the hinge 3.

En référence à la figure 2, et aux figures 4 à 6, la charnière 3 comprend un mécanisme de conversion d'un mouvement de rotation en un mouvement de translation.In reference to the figure 2 , and to figures 4 to 6 , the hinge 3 includes a mechanism for converting a rotational movement into a translational movement.

Ce mécanisme de conversion comprend un organe intermédiaire 43 qui est mobile en translation sous l'effet du moteur électrique 40.This conversion mechanism comprises an intermediate member 43 which is movable in translation under the effect of the electric motor 40.

En référence à la figure 2 :

  • le moteur 40 et le réducteur 41 permettent d'entraîner en rotation une vis 42 ;
  • le mécanisme de conversion correspond à une vis à billes, l'organe intermédiaire 43 étant plus particulièrement un écrou 430.
In reference to the figure 2 :
  • the motor 40 and the reduction gear 41 make it possible to rotate a screw 42;
  • the conversion mechanism corresponds to a ball screw, the intermediate member 43 being more particularly a nut 430.

L'écrou 430 est couplé sur la vis 42.Nut 430 is coupled to screw 42.

L'organe intermédiaire 43, et plus particulièrement l'écrou 430, est mobile le long d'un axe de translation T qui est formé par l'axe d'extension de la vis 42.The intermediate member 43, and more particularly the nut 430, is movable along a translation axis T which is formed by the extension axis of the screw 42.

Selon le premier mode de réalisation illustré par la figure 2, dans lequel l'ouvrant 1 est uniquement monté mobile en rotation sur le dormant 2, la charnière 3 comprend également un bras de transmission 7 qui couple l'organe intermédiaire 43 à l'ouvrant 1. Plus particulièrement, le bras de transmission 7 couple l'organe intermédiaire 43 au couvercle 10.According to the first embodiment illustrated by the figure 2 , in which the opening 1 is only mounted to move in rotation on the frame 2, the hinge 3 also comprises a transmission arm 7 which couples the intermediate member 43 to the opening 1. More particularly, the transmission arm 7 couples the intermediate member 43 to the cover 10.

Tel qu'illustré par la figure 2, le bras de transmission 7 est plus précisément couplé par une première extrémité à l'ouvrant 1 sur un premier point de pivot 71 qui est excentré de l'axe de rotation R de l'ouvrant 1. Le bras de transmission 7 est également couplé par une seconde extrémité, opposée à la première extrémité, à l'organe intermédiaire 43 sur un second point de pivot 72.As illustrated by the figure 2 , the transmission arm 7 is more precisely coupled by a first end to the opening 1 on a first pivot point 71 which is eccentric from the axis of rotation R of the opening 1. The transmission arm 7 is also coupled through a second end, opposite the first end, to the intermediate member 43 on a second pivot point 72.

Le dispositif 1 est configuré de manière à ce qu'une translation de l'organe intermédiaire 43 selon un premier sens entraîne l'ouverture de l'ouvrant 1, et qu'une translation de l'organe intermédiaire 43 selon un second sens entraîne une fermeture de l'ouvrant 1.The device 1 is configured in such a way that a translation of the intermediate member 43 in a first direction causes the opening of the opening 1, and that a translation of the intermediate member 43 in a second direction causes a closing of sash 1.

Selon le deuxième mode de réalisation illustré par les figures 4 à 6, dans lequel l'ouvrant 1 présente une mobilité en translation entre sa position d'ouverture intermédiaire et sa position fermée, la charnière 3 présente les mêmes caractéristiques que celle du premier mode de réalisation, et comprend également au moins un bâti mobile 8 monté mobile en translation sur au moins un élément de guidage 80 en translation présenté par le dormant 2.According to the second embodiment illustrated by the figures 4 to 6 , in which the opening 1 has mobility in translation between its intermediate opening position and its closed position, the hinge 3 has the same characteristics as that of the first embodiment, and also comprises at least one movable frame 8 mounted movably in translation on at least one guide element 80 in translation presented by the frame 2.

Plus précisément, la charnière 3 comprend deux bâtis mobiles 8, soit un bâti mobile 8 pour chaque sous-ensemble.More precisely, the hinge 3 comprises two movable frames 8, i.e. one movable frame 8 for each subassembly.

L'ouvrant 1 est alors monté mobile en rotation sur le ou les bâtis mobiles 8.The opening 1 is then mounted to move in rotation on the mobile frame(s) 8.

Des chemins de came complémentaires, dont un premier chemin de came C1 et un deuxième chemin de came C2 présentés par le dormant 2 et/ou par les bâtis mobiles 8, permettent de transformer le mouvement de translation de l'organe intermédiaire 43 le long de l'axe de translation T soit en un mouvement de translation de l'ouvrant 1, soit en un mouvement de rotation de l'ouvrant 1.Complementary cam paths, including a first cam path C1 and a second cam path C2 presented by the frame 2 and/or by the movable frames 8, make it possible to transform the translation movement of the intermediate member 43 along the translation axis T either in a translation movement of the opening 1, or in a rotational movement of the opening 1.

Plus spécifiquement, selon le mode de réalisation illustré par les figures 4 à 6, le bâti mobile 8 porte l'axe de rotation R et un second axe de rotation A ;
De plus, l'ouvrant 1 comprend une partie fixe 11 s'étendant à l'intérieur du caisson 20 dans la position fermée de l'ouvrant 1. Cette partie fixe est solidaire d'un plan principal de l'ouvrant 1.More specifically, according to the embodiment illustrated by the figures 4 to 6 , the mobile frame 8 carries the axis of rotation R and a second axis of rotation A;
In addition, the opening 1 comprises a fixed part 11 extending inside the box 20 in the closed position of the opening 1. This fixed part is integral with a main plane of the opening 1.

La partie fixe 11 coopère avec le bâti mobile 8 pour permettre à l'ouvrant 1 d'être mobile en rotation autour de l'axe de rotation R.The fixed part 11 cooperates with the movable frame 8 to allow the opening 1 to be movable in rotation around the axis of rotation R.

Selon le présent mode de réalisation, la charnière 3 comprend :

  • une première came P1 mobile dans le premier chemin de came C1, la première came P1 étant également le premier point de pivot 71 auquel est couplé le bras de transmission 7 ;
  • une deuxième came P2 mobile dans le deuxième chemin de came C2 ;
  • un deuxième bras de transmission 73 couplé à la première came P1 à une première extrémité et à la deuxième came P2 à une deuxième extrémité ;
  • un troisième bras de transmission 74 couplé à la deuxième came P2 à une extrémité et au second axe de rotation A à une deuxième extrémité.
According to this embodiment, the hinge 3 comprises:
  • a first cam P1 movable in the first cam path C1, the first cam P1 also being the first pivot point 71 to which the transmission arm 7 is coupled;
  • a second cam P2 movable in the second cam path C2;
  • a second transmission arm 73 coupled to the first cam P1 at a first end and to the second cam P2 at a second end;
  • a third transmission arm 74 coupled to the second cam P2 at one end and to the second axis of rotation A at a second end.

Tel que cela est illustré par les figures 4 et 5, la translation de l'organe intermédiaire 43 le long d'une première section de la vis 42 entraîne une translation du bâti mobile 8 entre une position basse et une position haute, et ainsi une translation de l'ouvrant 1 entre sa position fermée et sa position d'ouverture intermédiaire.As illustrated by the figures 4 And 5 , the translation of the intermediate member 43 along a first section of the screw 42 causes a translation of the mobile frame 8 between a low position and a high position, and thus a translation of the opening 1 between its closed position and its intermediate opening position.

Cette translation du bâti mobile 8 est permise grâce au premier chemin de came C1 et au deuxième chemin de came C2 qui présentent chacun une portion rectiligne. La translation de l'organe intermédiaire 43 le long de la première section de la vis 42 entraîne, grâce au bras de transmission 7, au deuxième bras de transmission 73, au troisième bras de transmission 74, ainsi qu'aux contraintes exercées par les chemins de cames, le déplacement de la première came P1 et de la deuxième came P2 uniquement le long des portions rectilignes de leur chemin de came respectives.This translation of the mobile frame 8 is enabled thanks to the first cam path C1 and the second cam path C2 which each have a rectilinear portion. The translation of the intermediate member 43 along the first section of the screw 42 causes, thanks to the transmission arm 7, the second transmission arm 73, the third transmission arm 74, as well as the constraints exerted by the paths of cams, the movement of the first cam P1 and the second cam P2 only along the rectilinear portions of their respective cam paths.

Tel que cela est illustré par les figures 5 et 6, la translation de l'organe intermédiaire 43 le long d'une seconde section de la vis 42 entraîne une rotation de l'ouvrant 1 autour de l'axe de rotation R qui est situé sur le ou les bâtis mobiles 8, et ainsi une rotation de l'ouvrant 1 par rapport au dormant 2.As illustrated by the figures 5 And 6 , the translation of the intermediate member 43 along a second section of the screw 42 causes a rotation of the opening 1 around the axis of rotation R which is located on the movable frame(s) 8, and thus a rotation of the opening 1 relative to the frame 2.

Cette rotation de l'ouvrant 1 est permise grâce au premier chemin de came C1 et au deuxième chemin de came C2 qui présentent chacun une portion courbe qui prolonge leur portion rectiligne. La translation de l'organe intermédiaire 43 le long de la deuxième section de la vis 42 entraîne quant à elle, grâce au bras de transmission 7, au deuxième bras de transmission 73, au troisième bras de transmission 74, ainsi qu'aux contraintes exercées par les chemins de cames, le déplacement de la première came P1 et de la deuxième came P2 uniquement le long des portions courbes de leur chemin de came respectives. La première came P1 et la deuxième came P2 sont alors plus spécifiquement entraînées en rotation autour respectivement de l'axe de rotation R et du second axe de rotation A.This rotation of the opening 1 is allowed thanks to the first cam path C1 and the second cam path C2 which each have a curved portion which extends their rectilinear portion. The translation of the intermediate member 43 along the second section of the screw 42 causes, thanks to the transmission arm 7, the second transmission arm 73, the third transmission arm 74, as well as the stresses exerted by the cam paths, the movement of the first cam P1 and the second cam P2 only along the curved portions of their respective cam paths. The first cam P1 and the second cam P2 are then more specifically rotated around the axis of rotation R and the second axis of rotation A respectively.

Tel qu'expliqué précédemment, les moyens de détermination 5 permettent d'obtenir la force exercée E et/ou une vitesse de déplacement D de l'ouvrant 1.As explained previously, the determination means 5 make it possible to obtain the force exerted E and/or a speed of movement D of the opening 1.

A titre principal, cette détermination est réalisée de manière indirecte.Mainly, this determination is made indirectly.

En effet, les moyens de détermination 5 comprennent un premier capteur 51 de position d'un organe de la charnière, dit « organe témoin ».Indeed, the determination means 5 comprise a first sensor 51 for the position of a hinge member, called a “control member”.

Les moyens de détermination 5 sont ainsi paramétrés pour calculer la force exercée E, et/ou la vitesse de déplacement D de l'ouvrant 1, à partir d'un déplacement de l'organe témoin engendré par l'application de l'effort sur l'ouvrant 1.The determination means 5 are thus configured to calculate the force exerted E, and/or the speed of movement D of the opening 1, from a movement of the witness member generated by the application of the force on opening 1.

Selon les présents modes de réalisation, l'organe de transmission 43 forme l'organe témoin.According to the present embodiments, the transmission member 43 forms the control member.

Plus précisément, le premier capteur 51 de position permet de déterminer la position de l'organe intermédiaire 43, et plus précisément de l'écrou 430, le long de son axe de translation T. La position de l'ouvrant 1 par rapport au dormant 2 est alors corrélée à la position de l'organe intermédiaire 43 le long de l'axe de translation T.More precisely, the first position sensor 51 makes it possible to determine the position of the intermediate member 43, and more precisely of the nut 430, along its axis of translation T. The position of the opening 1 relative to the frame 2 is then correlated to the position of the intermediate member 43 along the translation axis T.

L'évolution de la position de l'organe intermédiaire 43 le long de l'axe de translation T permet notamment de déterminer l'évolution de la position de l'ouvrant 1.The evolution of the position of the intermediate member 43 along the translation axis T makes it possible in particular to determine the evolution of the position of the opening 1.

En d'autres termes, la position réelle de l'écrou 430 et sa vitesse de déplacement permettent aux moyens de détermination de calculer la position de l'ouvrant 1 et sa vitesse de déplacement D.In other words, the real position of the nut 430 and its speed of movement allow the determination means to calculate the position of the opening 1 and its speed of movement D.

De plus, en étant couplés au moteur électrique 40, les moyens de détermination 5 intègrent une valeur de couple moteur instantané délivrée par le moteur électrique, voire de couple résistant si le moteur exerce un couple allant à l'encontre d'une rotation de la vis 42 et d'un déplacement de l'organe intermédiaire 43.Furthermore, by being coupled to the electric motor 40, the determination means 5 integrate a value of instantaneous motor torque delivered by the electric motor, or even of resistant torque if the motor exerts a torque going against a rotation of the screw 42 and a movement of the intermediate member 43.

L'ensemble de ces données (couple du moteur électrique 40, position réelle de l'écrou 430 et vitesse instantanée de l'écrou 430) permet de déterminer une résistance à la fermeture de l'ouvrant 1 exercée par le moteur électrique 40, et de réaliser un calcul, par le biais des moyens de détermination 5, de la valeur de la force exercée E.All of these data (torque of the electric motor 40, real position of the nut 430 and instantaneous speed of the nut 430) makes it possible to determine a resistance to the closing of the opening 1 exerted by the electric motor 40, and to carry out a calculation, via the determination means 5, of the value of the force exerted E.

En référence au second mode de réalisation illustré par les figures 4 à 6, et dans lequel l'ouvrant 1 peut adopter une position d'ouverture intermédiaire (figure 5), l'unité électronique 6 est en outre paramétrée pour piloter le moteur électrique 40 pour qu'il tende à maintenir l'ouvrant 1 dans sa position d'ouverture intermédiaire.With reference to the second embodiment illustrated by the figures 4 to 6 , and in which the opening 1 can adopt an intermediate opening position ( figure 5 ), the electronic unit 6 is also configured to control the electric motor 40 so that it tends to maintain the opening 1 in its intermediate opening position.

Le moteur électrique 40 utilise alors son couplage aux moyens de détermination 5 pour exercer une résistance R (soit un couple résistant) allant à l'encontre d'une translation de l'ouvrant 1 de sa position d'ouverture intermédiaire à sa position fermée.The electric motor 40 then uses its coupling to the determination means 5 to exert a resistance R (i.e. a resistant torque) going against a translation of the opening 1 from its intermediate opening position to its closed position.

Avantageusement, la résistance R est égale à la force seuil S.Advantageously, the resistance R is equal to the threshold force S.

L'ouvrant 1 dans sa position d'ouverture intermédiaire reste ainsi dans sa position d'ouverture intermédiaire si un utilisateur applique un effort sur l'ouvrant 1 pour le fermer et que cet effort ne produit pas une force exercée E égale ou supérieure à la force seuil S.The opening 1 in its intermediate opening position thus remains in its intermediate opening position if a user applies an effort on the opening 1 to close it and this effort does not produce an exerted force E equal to or greater than the threshold force S.

Dès que l'utilisateur exerce un effort suffisant et que la force exercée E est égale ou supérieure à la force seuil S, alors le moteur entraîne la fermeture de l'ouvrant 1 en entraînant son passage en position fermée.As soon as the user exerts sufficient effort and the force exerted E is equal to or greater than the threshold force S, then the motor causes the closing of the opening 1 by causing it to move into the closed position.

A titre secondaire, la détermination de la force exercée E peut être réalisée de manière directe.Secondary, the determination of the force exerted E can be carried out directly.

En effet, en référence aux figures 3 et 5, les moyens de détermination 5 comprennent un second capteur 52 de position de l'ouvrant 1 par rapport au cadre 200. Ce second capteur 52 est bien entendu indépendant du premier capteur 51.Indeed, with reference to figures 3 And 5 , the determination means 5 comprise a second sensor 52 for the position of the opening 1 relative to the frame 200. This second sensor 52 is of course independent of the first sensor 51.

Ce second capteur 52 est positionné à proximité immédiate du cadre 200.This second sensor 52 is positioned in the immediate vicinity of the frame 200.

Plus précisément, le second capteur 52 est positionné à proximité immédiate d'un bord avant 201 du cadre 200, opposé à un bord arrière 202 du cadre 200, la charnière 3 étant positionnée dans le dormant 2 du côté du bord arrière 202 du cadre 200.More precisely, the second sensor 52 is positioned in the immediate vicinity of a front edge 201 of the frame 200, opposite a rear edge 202 of the frame 200, the hinge 3 being positioned in the frame 2 on the side of the rear edge 202 of the frame 200 .

Selon le présent mode de réalisation le second capteur 52 est un capteur à effet Hall et un aimant 520 complémentaire du capteur à effet Hall est porté par l'ouvrant en vis-à-vis du second capteur 52.According to the present embodiment, the second sensor 52 is a Hall effect sensor and a magnet 520 complementary to the Hall effect sensor is carried by the opening facing the second sensor 52.

Un tel capteur à effet Hall permet de mesurer une variation de champ magnétique et permet ainsi de détecter la position de l'aimant 520 par rapport au second capteur 52 et ainsi de déterminer la position de l'ouvrant 1 par rapport au bord avant 201 du cadre 200.Such a Hall effect sensor makes it possible to measure a variation in the magnetic field and thus makes it possible to detect the position of the magnet 520 relative to the second sensor 52 and thus to determine the position of the opening 1 relative to the front edge 201 of the frame 200.

Les moyens de détermination 5 sont alors paramétrés pour corréler un signal du second capteur 52 engendré par l'application d'un effort sur l'ouvrant 1 dans sa position d'ouverture intermédiaire à la force exercée E.The determination means 5 are then configured to correlate a signal from the second sensor 52 generated by the application of a force on the opening 1 in its intermediate opening position to the force exerted E.

En référence à la figure 5, un tel second capteur 52 permet de compenser la présence d'un moment parasite, résultant d'un effet de levier, dans le cas où une première force F1 est appliquée sur une partie avant de l'ouvrant 1. En effet, l'application d'une force sur une partie avant de l'ouvrant 1 provoque l'apparition d'un moment parasite du fait de la distance de la partie avant de l'ouvrant 1 par rapport à la charnière 3.In reference to the figure 5 , such a second sensor 52 makes it possible to compensate for the presence of a parasitic moment, resulting from a leverage effect, in the case where a first force F1 is applied to a front part of the opening 1. In fact, the application of a force on a front part of the opening 1 causes the appearance of a parasitic moment due to the distance of the front part of the opening 1 relative to the hinge 3.

Ainsi, le premier capteur 51, en étant intégré dans la charnière 3, permet une meilleure détection d'une seconde force F2 appliquée sur une partie arrière de l'ouvrant 1, à proximité de la charnière 3, comparativement à la détection de la première force F1.Thus, the first sensor 51, by being integrated into the hinge 3, allows better detection of a second force F2 applied to a rear part of the opening 1, near the hinge 3, compared to the detection of the first force F1.

Le second capteur 52 permet in fine de corriger la force déterminée et augmente la précision des moyens de détermination 5 pour obtenir la bonne force exercée E.The second sensor 52 ultimately makes it possible to correct the determined force and increases the precision of the determination means 5 to obtain the correct force exerted E.
