Abstract

The oven door lock comprises a lever (3), accessible from the oven front, which can be rotated about a spindle (4), parallel to the door hinge, mounted on the oven chassis (C). A stop (5) extending from the lever spindle to the inside of the oven has a free end (5a). The stop rotates with the lever about the spindle. The lever is in the active position when the stop free end obstructs the passage of a strike plate (6), located on the door perimeter, during door opening. This prevents the door being opened. The inactive position is obtained by manual displacement of the lever towards the door handle (2) so as to move the door away from the stop free end and free passage of the strike plate. The door can then be opened by pulling on the handle.

Description

La présente invention a pour objet un dispositif de sécurité pour l'ouverture de la porte d'un appareil de cuisson domestique, notamment d'un four, encastrable ou non, ou encore d'une cuisinière.The present invention relates to a safety device for opening the door of a domestic cooking appliance, in particular an oven, built-in or not, or even a stove.

Lorsque ce type d'appareils est utilisé dans un environnement où peuvent évoluer des enfants, on conçoit aisément qu'il est indispensable de prévoir un système qui n'autorise l'ouverture de la porte qu'à des adultes.When this type of device is used in an environment where children can evolve, it is easy to see that it is essential to provide a system that only allows the door to be opened by adults.

Tous les systèmes connus reposent sur le fait qu'on impose à l'utilisateur d'effectuer une double manipulation, à savoir un actionnement préalable pour désactiver la sécurité, puis une traction sur la poignée de la porte pour ouvrir celle-ci. Cette double manipulation rend plus difficile l'ouverture de la porte et permet en conséquence d'éviter que des enfants soient à même d'ouvrir seuls la porte.All known systems are based on the fact that the user is required to perform a double manipulation, namely a prior actuation to deactivate the security, then a pull on the door handle to open it. This double manipulation makes it more difficult to open the door and consequently prevents children from being able to open the door alone.

Les systèmes connus à l'heure actuelle sont installés sur la poignée de la porte du four. Cela présente l'avantage évident de permettre à l'utilisateur d'ouvrir la porte d'une même main. En contrepartie cependant, un système de sécurité donné intégré à la poignée de la porte n'est pas transposable tel quel à une autre gamme d'appareils de cuisson pour laquelle, pour des raisons notamment d'esthétisme, la poignée aura une forme différente.The systems known at present are installed on the handle of the oven door. This has the obvious advantage of allowing the user to open the door with one hand. On the other hand, however, a given security system integrated into the door handle cannot be transposed as such to another range of cooking appliances for which, for reasons notably of aesthetics, the handle will have a different shape.

En outre, dans le cas des portes de fours ou de cuisinières abattantes, pour lesquelles la poignée est horizontale, généralement dans la partie supérieure de la porte, les sécurités connues consistent en l'actionnement latéral d'un dispositif, généralement de la gauche vers la droite. Ce type de dispositif est très bien adapté aux utilisateurs qui sont droitiers, alors qu'il s'avère être une gêne pour les gauchers.In addition, in the case of oven doors or drop-down cookers, for which the handle is horizontal, generally in the upper part of the door, the known safety means consist in lateral actuation of a device, generally from the left towards the right. This type of device is very well suited to users who are right-handed, while it turns out to be a nuisance for left-handers.

La présente invention a pour but de proposer un dispositif de sécurité fonctionnant sur le principe de la double manipulation, mais qui ne présente pas les inconvénients mentionnés ci-dessus.The present invention aims to provide a safety device operating on the principle of double manipulation, but which does not have the drawbacks mentioned above.

Plus précisément, l'invention a pour objet un dispositif de sécurité pour l'ouverture de la porte d'un appareil de cuisson, ladite porte comportant une poignée, le dispositif de sécurité étant caractérisé en ce qu'il comporte un levier accessible au niveau de la façade de l'appareil de cuisson et susceptible d'être déplacé en rotation autour d'un axe sensiblement parallèle à l'axe de rotation de la porte et monté sur le châssis de l'appareil, et une butée s'étendant depuis l'axe vers l'intérieur de l'appareil et possédant une extrémité libre, ladite butée étant solidaire du levier en rotation autour de l'axe, le dispositif de sécurité étant susceptible d'être dans une première position dite activée, dans laquelle l'extrémité libre de la butée vient obstruer le passage d'une gâche située sur le contour de la porte lors de l'ouverture de celle-ci, et dans une deuxième position dite désactivée, obtenue par déplacement manuel du levier vers la poignée, entraînant la butée en rotation autour de l'axe de façon à éloigner de la porte l'extrémité libre de la butée, et libérer le passage de la gâche.More specifically, the invention relates to a safety device for opening the door of a cooking appliance, said door comprising a handle, the safety device being characterized in that it comprises a lever accessible at the front of the cooking appliance and capable of being rotated about an axis substantially parallel to the axis of rotation of the door and mounted on the chassis of the apparatus, and a stop extending from the axis towards the interior of the apparatus and having a free end, said stop being integral with the lever rotating about the axis , the safety device being capable of being in a first so-called activated position, in which the free end of the stopper obstructs the passage of a keeper situated on the contour of the door when the latter is opened , and in a second so-called deactivated position, obtained by manual movement of the lever towards the handle, driving the stop in rotation about the axis so as to move the free end of the stop away from the door, and free the passage of spoils.

Comme le dispositif selon l'invention est placé sur le châssis, et non sur la poignée, et qu'il est par ailleurs très peu visible depuis l'extérieur (seul le levier est apparent), un même dispositif peut être utilisé pour plusieurs gammes d'appareils de cuisson, indépendamment de l'esthétisme que l'on veut donner à la façade avant de l'appareil.As the device according to the invention is placed on the chassis, and not on the handle, and moreover it is hardly visible from the outside (only the lever is visible), the same device can be used for several ranges cooking appliances, regardless of the aesthetics that you want to give to the front of the appliance.

De plus, le déplacement du levier peut se faire aisément, que l'utilisateur soit droitier ou gaucher.In addition, the movement of the lever can be done easily, whether the user is right-handed or left-handed.

Par ailleurs, dans une variante tout à fait avantageuse de la présente invention, le dispositif de sécurité peut être neutralisé par une action volontaire de l'utilisateur.Furthermore, in an entirely advantageous variant of the present invention, the safety device can be neutralized by voluntary action by the user.

A l'heure actuelle, aucun système connu n'offre cette possibilité de sorte qu'un utilisateur doit toujours, même lorsqu'il n'y a pas d'enfants à proximité, faire usage de cette sécurité, ce qui peut représenter, à terme, un inconvénient. En terme de commercialisation, il est également beaucoup plus intéressant de proposer un appareil de cuisson à un large éventail d'utilisateurs, ces derniers ayant postérieurement la possibilité d'utiliser ou non la sécurité.At present, no known system offers this possibility so that a user must always, even when there are no children nearby, make use of this security, which can represent, at term, a drawback. In terms of marketing, it is also much more interesting to offer a cooking appliance to a wide range of users, the latter subsequently having the option of using security or not.

A cette fin, le dispositif selon l'invention peut comporter en outre des moyens susceptibles de placer le dispositif de sécurité dans un état dit neutralisé, dans lequel la butée est, par rapport au levier, dans une position angulaire telle que le passage de la gâche est toujours libéré, quelle que soit la position du levier.To this end, the device according to the invention may further comprise means capable of placing the safety device in a so-called neutralized state, in which the stop is, relative to the lever, in an angular position such that the passage of the keeper is always released, regardless of the position of the lever.

Les différents aspects de l'invention seront mieux compris au vu de la description suivante faite en référence aux figures annexées dans lesquelles :

  • Les figures 1a et 1b sont des vues partielles de côté de la façade avant d'un appareil de cuisson illustrant le dispositif de sécurité respectivement dans sa position activée et dans sa position désactivée ;
  • Les figures 2a et 2b illustrent une mise en oeuvre particulière d'un dispositif selon l'invention, respectivement dans une position non neutralisée, et dans une position neutralisée ;
  • Les figures 3a et 3b sont des vues en coupe dans le plan contenant le levier 3 des figures 2a et 2b.
The various aspects of the invention will be better understood in view of the following description made with reference to the appended figures in which:
  • Figures 1a and 1b are partial side views of the front panel of a cooking appliance illustrating the safety device in its activated position and in its deactivated position respectively;
  • Figures 2a and 2b illustrate a particular implementation of a device according to the invention, respectively in a non-neutralized position, and in a neutralized position;
  • Figures 3a and 3b are sectional views in the plane containing the lever 3 of Figures 2a and 2b.

Sur les figures 1a et 1b, on a représenté partiellement, en coupe latérale, la façade avant d'un appareil de cuisson à porte abattante 1, équipé d'un dispositif de sécurité selon l'invention. Dans le cas d'une porte abattante, la poignée 2 est horizontale. Le dispositif de sécurité comporte d'une part un levier 3 accessible pour l'utilisateur au niveau de la façade de l'appareil, et une butée 5. Le levier 3 et la butée 5 sont solidaires en rotation autour d'un axe 4 fixé au châssis C de l'appareil de cuisson, et s'étendant parallèlement à la poignée de la porte et à l'axe de rotation de la porte.In Figures 1a and 1b, there is shown partially, in side section, the front face of a cooking appliance with a flap door 1, equipped with a safety device according to the invention. In the case of a drop-down door, the handle 2 is horizontal. The safety device comprises on the one hand a lever 3 accessible to the user at the front of the device, and a stop 5. The lever 3 and the stop 5 are integral in rotation around a fixed axis 4 to frame C of the cooking appliance, and extending parallel to the door handle and to the axis of rotation of the door.

Dans la position activée représentée sur la figure 1a, le dispositif de sécurité est tel que l'extrémité libre 5a de la butée repose sur la partie supérieure de la porte. Selon l'invention, cette extrémité libre vient dans cette position obstruer le passage d'une gâche 6 située sur la partie supérieure de la porte. Il n'est donc pas possible pour un utilisateur d'ouvrir la porte tant que le dispositif de sécurité est activé.In the activated position shown in FIG. 1a, the safety device is such that the free end 5a of the stop rests on the upper part of the door. According to the invention, this free end comes in this position to obstruct the passage of a keeper 6 located on the upper part of the door. It is therefore not possible for a user to open the door as long as the safety device is activated.

Pour désactiver le dispositif de sécurité, il suffit de déplacer manuellement le levier 3 vers la poignée de la porte, c'est-à-dire vers le bas dans l'exemple illustré sur la figure 1b, comme indiqué par la flèche F1. La butée 5, qui est solidaire du levier dans sa rotation autour de l'axe 4, est alors entraînée sur un parcours angulaire suffisant pour éloigner du haut de la porte l'extrémité libre 5a de la butée, et libérer le passage de la gâche. Il est alors possible d'ouvrir la porte 1 en tirant sur la poignée 2.To deactivate the safety device, it suffices to manually move the lever 3 towards the door handle, that is to say down in the example illustrated in FIG. 1b, as indicated by the arrow F 1 . The stop 5, which is integral with the lever in its rotation about the axis 4, is then driven over an angular path sufficient to move the free end 5a of the stop from the top of the door, and free the passage of the striker . It is then possible to open the door 1 by pulling on the handle 2.

Dans un mode préférentiel de réalisation du dispositif de sécurité selon l'invention, un ressort de rappel 7 permet au dispositif de sécurité de retourner automatiquement dans sa position activée dès lors que l'utilisateur n'appuie plus sur le levier. Le déplacement, automatique ou non, du levier 3 dans le sens inverse à la flèche F1 est de préférence limité, par exemple par un rebord 8 fixé au châssis C de l'appareil, sur lequel le levier 3 vient buter.In a preferred embodiment of the safety device according to the invention, a return spring 7 allows the safety device to automatically return to its activated position as soon as the user no longer presses the lever. The movement, automatic or not, of the lever 3 in the opposite direction to the arrow F 1 is preferably limited, for example by a flange 8 fixed to the chassis C of the device, on which the lever 3 abuts.

En référence aux figures 2a et 2b, un mode de réalisation particulièrement avantageux du dispositif de sécurité selon l'invention consiste à prévoir le levier 3 et la butée 5 sous forme de deux pièces distinctes montées libres en rotation autour de l'axe, et solidarisées en rotation par des formes particulières données à ces deux pièces. Plus précisément, le levier 3 possède un premier épaulement 30 sur lequel vient s'appuyer un prolongement 50 de la butée s'étendant le long de l'axe 4. La façon dont vient prendre appui ce prolongement permet aux deux pièces d'être solidarisées en rotation et d'avoir un positionnement angulaire relatif rendant possible, lorsque le levier 3 est actionné dans le sens de la flèche F1 (figures 1b et 2a), l'entraînement en rotation de la butée sur un parcours angulaire suffisant pour libérer le passage de la gâche 6.With reference to FIGS. 2a and 2b, a particularly advantageous embodiment of the safety device according to the invention consists in providing the lever 3 and the stop 5 in the form of two separate parts mounted free in rotation around the axis, and secured in rotation by particular shapes given to these two parts. More precisely, the lever 3 has a first shoulder 30 on which an extension 50 of the abutment extending along the axis 4 rests. The way in which this extension comes to bear allows the two parts to be secured in rotation and to have a relative angular positioning making it possible, when the lever 3 is actuated in the direction of the arrow F 1 (FIGS. 1b and 2a), to drive the stop in rotation over an angular path sufficient to release the strike plate 6.

Dans une variante préférée de l'invention, le dispositif de sécurité comporte en outre des moyens qui permettent de neutraliser volontairement et simplement le dispositif de sécurité, c'est-à-dire de positionner la butée angulairement par rapport au levier de façon telle qu'elle n'obstrue jamais le passage de la gâche, et ce, quelle que soit la position du levier, et en particulier lorsque ce dernier n'est pas actionné par l'utilisateur.In a preferred variant of the invention, the safety device furthermore comprises means which make it possible to neutralize the safety device voluntarily and simply, that is to say to position the stop angularly relative to the lever so that 'It never obstructs the passage of the striker, and this, whatever the position of the lever, and in particular when the latter is not actuated by the user.

Un exemple de tels moyens est illustré sur les figures 2a, 2b et 3a, 3b :An example of such means is illustrated in FIGS. 2a, 2b and 3a, 3b:

Dans cet exemple, le levier 3 comprend un second épaulement 31 sur lequel le prolongement 50 de la butée 5 est susceptible de venir s'appuyer (figures 2b et 3b).In this example, the lever 3 comprises a second shoulder 31 on which the extension 50 of the stop 5 is capable of coming to bear (Figures 2b and 3b).

Plus précisément, l'utilisateur qui souhaite neutraliser le dispositif de sécurité déplace manuellement la butée 5 en rotation autour de l'axe 4, comme l'indique la flèche F2 sur la figure 2b. Cette action libère le prolongement 50 du premier épaulement 30. Le levier est en outre susceptibe d'être translaté manuellement le long de l'axe 4. Par cette translation, on amène le prolongement 50 en appui sur le deuxième épaulement 31. La façon dont vient prendre appui ce prolongement permet là encore aux deux pièces d'être solidarisées en rotation. Cependant, le positionnement angulaire de la butée et du levier est tel que l'extrémité 5a de la butée ne peut jamais venir obstruer le passage de la gâche, et ce, même lorsque le dispositif est supposé être dans une position activée.More specifically, the user who wishes to neutralize the safety device manually moves the stop 5 in rotation about the axis 4, as indicated by the arrow F 2 in FIG. 2b. This action frees the extension 50 from the first shoulder 30. The lever is also capable of being manually translated along the axis 4. By this translation, the extension 50 is brought to bear on the second shoulder 31. The way in which comes to bear this extension again allows the two parts to be secured in rotation. However, the angular positioning of the stop and the lever is such that the end 5a of the stop can never obstruct the passage of the strike, even when the device is supposed to be in an activated position.

Si l'utilisateur souhaite remettre en service le dispositif de sécurité, il lui suffit de translater le levier dans le sens inverse à la flèche F3. Le prolongement 50 de la butée vient alors automatiquement en appui sur le premier épaulement. La position angulaire de la butée est alors suffisante pour entraver l'ouverture de la porte (figure 1a).If the user wishes to put the safety device back into service, he simply has to translate the lever in the opposite direction to the arrow F 3 . The extension 50 of the stop then automatically comes to bear on the first shoulder. The angular position of the stop is then sufficient to hinder the opening of the door (Figure 1a).

La présente invention a été décrite dans le cadre d'un appareil de cuisson à porte abattante. Bien entendu, le système est facilement transposable aux portes à ouverture latérale.The present invention has been described in the context of a cooking appliance with a drop-down door. Of course, the system can easily be transposed to doors with lateral opening.
