Description

La présente invention concerne de manière générale une cartonnette de sac d'aspirateur, le sac d'aspirateur étant destiné à être monté sur ou dans un aspirateur par le biais de cette cartonnette.The present invention generally relates to a vacuum cleaner cardboard bag, the vacuum bag being intended to be mounted on or in a vacuum cleaner by means of this cardboard.

Il est connu dans l'art antérieur des sacs d'aspirateur avec des cartonnettes, comme en particulier celle divulguée dans le document JP08173359 . En contrepartie, ce système présente notamment l'inconvénient de comporter une came latérale à la cartonnette, ce qui peut présenter des risques de coincement et de non-qualité de fonctionnement.It is known in the prior art vacuum bags with cardboard, as in particular that disclosed in the document JP08173359 . In return, this system has the particular disadvantage of having a cam side to the cardboard, which can present risks of jamming and non-quality of operation.

Un but de la présente invention est de répondre aux inconvénients de l'art antérieur mentionnés ci-dessus et en particulier, tout d'abord, de proposer une cartonnette de sac d'aspirateur qui facilite le montage du sac d'aspirateur sur l'aspirateur, sans présenter de risques de coincement.An object of the present invention is to meet the disadvantages of the prior art mentioned above and in particular, first of all, to provide a vacuum cleaner cardboard that facilitates the mounting of the vacuum bag on the vacuum cleaner, without risk of jamming.

Pour cela un premier aspect de l'invention concerne une cartonnette de sac d'aspirateur agencée pour être fixée à un sac d'aspirateur, l'aspirateur comprenant :

  • un support de sac,
  • une cavité agencée pour recevoir le sac d'aspirateur,
  • un capot agencé pour fermer et ouvrir la cavité,
  • une butée, coulissante entre une première position et une deuxième position, la butée dans la première position étant agencée pour former une butée mécanique pour le capot et l'empêcher de fermer la cavité, et la butée dans la deuxième position étant agencée pour laisser le capot fermer la cavité,
la cartonnette étant agencée pour être montée sur le support de sac et comprenant des moyens de commande de la butée pour la placer dans la deuxième position lors d'un mouvement de montage de la cartonnette sur le support de sac,
caractérisée en ce que la butée comprend deux extrémités agencées de part et d'autre de la butée suivant une direction transversale par rapport à une direction de coulissement de la butée, et en ce que les moyens de commande de la butée sont deux ergots chacun agencé pour entrer en contact avec l'une des deux extrémités de la butée. La cartonnette selon la présente invention comporte deux ergots qui sont chacun agencé pour pousser la butée sur ses extrémités latérales. Ainsi, le risque de coincement ou d'arc-boutement est réduit puisqu'il y a deux points d'application de l'effort de la cartonnette sur la butée, et ces deux points sont le plus éloignés possible l'un de l'autre, car ils sont aux extrémités de la butée.For this, a first aspect of the invention relates to a vacuum cleaner cardboard arranged to be attached to a vacuum bag, the vacuum cleaner comprising:
  • a bag holder,
  • a cavity arranged to receive the vacuum bag,
  • a cover arranged to close and open the cavity,
  • a stop sliding between a first position and a second position, the stop in the first position being arranged to form a mechanical stop for the cover and prevent it from closing the cavity, and the stop in the second position being arranged to leave the hood close the cavity,
the cardboard being arranged to be mounted on the bag support and comprising means for controlling the stop to place it in the second position during a mounting movement of the cardboard on the bag support,
characterized in that the abutment comprises two ends arranged on either side of the abutment in a direction transverse to a direction of sliding of the abutment, and in that the control means of the abutment are two lugs each arranged to make contact with one of the two ends of the stop. The cardboard according to the present invention comprises two lugs which are each arranged to push the abutment on its lateral ends. Thus, the risk of jamming or jamming is reduced since there are two points of application of the force of the cardboard on the stop, and these two points are the farthest possible one of the other because they are at the ends of the abutment.

Selon un mode de réalisation, la cartonnette comprend deux parties latérales agencées sur un même plan pour former une interface de coulissement avec le support de sac, et les deux ergots sont en saillie par rapport au plan. Le fait de décaler les ergots en altitude par rapport au plan de la cartonnette, et en particulier le plan de guidage, permet de dissocier par construction les fonctions, et une non-conformité ou dérive dimensionnelle sur les ergots sera sans influence sur la fonction de coulissement, et une non-conformité ou dérive dimensionnelle sur les parties latérales de coulissement sera sans influence sur le déplacement de la butée.According to one embodiment, the cardboard comprises two lateral parts arranged on the same plane to form a sliding interface with the bag support, and the two pins are projecting with respect to the plane. The fact of shifting the lugs in altitude with respect to the plane of the cardboard, and in particular the guide plane, makes it possible to dissociate the functions by construction, and a nonconformity or dimensional drift on the lugs will have no influence on the function of sliding, and a nonconformity or dimensional drift on the lateral sliding parts will have no influence on the displacement of the stop.

Selon un mode de réalisation, l'aspirateur comprend un embout de flexible d'aspiration, la cartonnette comprend :

  • un corps plat comprenant les parties latérales,
  • un orifice agencé pour recevoir l'embout de flexible d'aspiration,
  • un opercule articulé et agencé pour occuper une position de fermeture de l'orifice lorsque ce dernier ne reçoit pas l'embout de flexible d'aspiration,
  • des moyens élastiques agencés pour maintenir l'opercule en position de fermeture,
et la cartonnette comprend une partie de fixation des moyens élastiques qui est une partie plane rabattue et maintenue sur le corps plan. La cartonnette selon cette mise en oeuvre est pratique à fabriquer, avec un simple rabat de la partie de fixation pour les mettre en tension.According to one embodiment, the vacuum cleaner comprises a suction hose nozzle, the cardboard comprises:
  • a flat body comprising the lateral parts,
  • an orifice arranged to receive the suction hose nozzle,
  • an articulated lid and arranged to occupy a closed position of the orifice when the latter does not receive the suction hose nozzle,
  • elastic means arranged to hold the lid in the closed position,
and the cardboard comprises a fixing part of the elastic means which is a flat part folded and held on the plane body. The cardboard according to this implementation is convenient to manufacture, with a simple flap of the fixing portion to put them in tension.

Selon un mode de réalisation, le corps plan et la partie de fixation sont agencés pour être réalisés par moulage par injection avec la même matière. La fabrication par moulage se fait en une seule étape, pour le corps plan et la partie de fixation, ce qui permet de surmouler les moyens élastiques (une lame de ressort, un ressort ou une épingle par exemple) à la partie de fixation, ce qui évite de devoir les assembler ensuite.According to one embodiment, the planar body and the fixing portion are arranged to be made by injection molding with the same material. The manufacturing by molding is done in a single step, for the flat body and the fixing part, which allows overmoulding the elastic means (a leaf spring, a spring or a pin for example) to the fixing part, this which avoids having to assemble them afterwards.

Selon un mode de réalisation, la cartonnette est agencée pour se monter en coulissant sur le support de sac jusqu'à une position de butée contre le support de sac.According to one embodiment, the cardboard is arranged to slidably mount on the bag support to a stop position against the bag support.

Selon un mode de réalisation, la cartonnette comprend des moyens de retenue agencés pour coopérer avec le support de sac et retenir la cartonnette sur le support de sac lorsqu'elle est en position de butée contre le support de sac. Ces moyens de retenue garantissent que la cartonnette restera en place une fois mise en place sur le support, par déformation élastique par exemple des moyens de retenue eux-mêmes ou d'une partie du support de sac, comme une lame flexible par exemple.According to one embodiment, the cardboard comprises retaining means arranged to cooperate with the bag support and retain the cardboard on the bag support when in abutment position against the bag support. These retaining means ensure that the cardboard remains in place once placed on the support, by elastic deformation, for example retaining means themselves or a portion of the bag support, such as a flexible blade for example.

Selon un mode de réalisation, le support de sac comprend des moyens élastiques, et les moyens de retenue sont des ailes en saillie par rapport au plan et agencées pour déformer les moyens élastiques du support de sac pour créer un effort de retenue. Cette mise en oeuvre permet de dissocier géométriquement la fonction de retenue avec la fonction de coulissement assurée par les parties latérales sur un même plan.According to one embodiment, the bag support comprises elastic means, and the retaining means are wings projecting from the plane and arranged to deform the elastic means of the bag support to create a retaining force. This implementation makes it possible to geometrically dissociate the retaining function with the sliding function provided by the lateral parts on the same plane.

Un deuxième aspect de l'invention concerne un sac d'aspirateur comprenant une cartonnette selon le premier aspect de l'invention.A second aspect of the invention relates to a vacuum bag comprising a cardboard according to the first aspect of the invention.

Un troisième aspect de l'invention concerne un dispositif de fixation de sac d'aspirateur comprenant un sac d'aspirateur selon le deuxième aspect de l'invention, et un support de sac d'un aspirateur.A third aspect of the invention relates to a vacuum bag attachment device comprising a vacuum bag according to the second aspect of the invention, and a bag holder of a vacuum cleaner.

Un dernier aspect de l'invention concerne un aspirateur comprenant :

  • un sac d'aspirateur avec un cartonnette,
  • un support de sac,
  • une cavité agencée pour recevoir le sac d'aspirateur,
  • un capot agencé pour fermer et ouvrir la cavité,
  • une butée, coulissante entre une première position et une deuxième position, la butée dans la première position étant agencée pour former une butée mécanique pour le capot et l'empêcher de fermer la cavité, et la butée dans la deuxième position étant agencée pour laisser le capot fermer la cavité,
la cartonnette étant agencée pour être montée sur le support de sac et comprenant des moyens de commande de la butée pour la placer dans la deuxième position lors d'un mouvement de montage de la cartonnette sur le support de sac,
caractérisé en ce que la butée comprend deux extrémités agencées de part et d'autre de la butée suivant une direction transversale par rapport à une direction de coulissement de la butée, et en ce que les moyens de commande de la butée sont deux ergots chacun agencé pour entrer en contact avec l'une des deux extrémités de la butée.A final aspect of the invention relates to a vacuum cleaner comprising:
  • a vacuum bag with a cardboard,
  • a bag holder,
  • a cavity arranged to receive the vacuum bag,
  • a cover arranged to close and open the cavity,
  • a stop sliding between a first position and a second position, the stop in the first position being arranged to form a mechanical stop for the cover and prevent it from closing the cavity, and the stop in the second position being arranged to leave the hood close the cavity,
the cardboard being arranged to be mounted on the bag support and comprising means for controlling the stop to place it in the second position during a mounting movement of the cardboard on the bag support,
characterized in that the abutment comprises two ends arranged on either side of the abutment in a direction transverse to a direction of sliding of the abutment, and in that the control means of the abutment are two lugs each arranged to make contact with one of the two ends of the stop.

Selon un mode de réalisation, la butée est embarquée sur le support de sac.According to one embodiment, the stop is embedded on the bag support.

D'autres caractéristiques et avantages de la présente invention apparaîtront plus clairement à la lecture de la description détaillée qui suit d'un mode de réalisation de l'invention donné à titre d'exemple nullement limitatif et illustré par les dessins annexés, dans lesquels :

  • les figures 1a et 1b représentent une coupe simplifiée d'un aspirateur sans et avec sac, respectivement ;
  • la figure 2 représente une cartonnette selon l'invention, montée sur un support de sac de l'aspirateur ;
  • la figure 3 représente une vue isométrique de la cartonnette de la figure 2.
Other features and advantages of the present invention will appear more clearly on reading the following detailed description of an embodiment of the invention given by way of non-limiting example and illustrated by the appended drawings, in which:
  • the Figures 1a and 1b represent a simplified section of a vacuum cleaner with and without a bag, respectively;
  • the figure 2 represents a cardboard according to the invention, mounted on a bag holder of the vacuum cleaner;
  • the figure 3 represents an isometric view of the cardboard of the figure 2 .

La figure 1a représente une coupe d'un aspirateur qui comprend une cavité 30 agencée pour recevoir un sac d'aspirateur, un support de sac 20 sur lequel une cartonnette 10 de sac d'aspirateur peut se monter, un capot 40 agencé pour ouvrir et fermer la cavité 30, et une butée 50.The figure 1a represents a section of a vacuum cleaner which comprises a cavity 30 arranged to receive a vacuum bag, a bag support 20 on which a cardboard 10 of vacuum bag can be mounted, a cover 40 arranged to open and close the cavity 30, and a stop 50.

Tel que représenté figure 1a, aucun sac d'aspirateur 15 n'est installé dans la cavité 30, sur le support de sac 20, et toute utilisation de l'aspirateur sera sans effet d'une part, et d'autre part, une telle utilisation dans ces conditions risque d'endommager l'aspirateur avec des poussières qui risquent d'être véhiculées dans le circuit de ventilation interne, en particulier dans le moto ventilateur. Pour prévenir un tel risque, l'aspirateur comprend la butée 50 qui, lorsqu'aucun sac d'aspirateur 15 n'est installé, est dans une première position telle que représentée et empêche le capot 40 de fermer la cavité 30 (en formant une butée mécanique pour le capot 40), ce qui alerte l'utilisateur que l'aspirateur n'est pas équipé d'un sac d'aspirateur 15. Le jeu j représenté entre le capot 40 et une poignée de l'aspirateur est important et indique à l'utilisateur que l'aspirateur n'est pas en configuration pour être utilisé.As shown figure 1a no vacuum bag 15 is installed in the cavity 30, on the bag support 20, and any use of the vacuum cleaner will be without effect on the one hand, and on the other hand, such use under these conditions risk of damaging the vacuum cleaner with dust which may be carried in the internal ventilation circuit, in particular in the motorcycle fan. To prevent such a risk, the vacuum cleaner comprises the stop 50 which, when no vacuum bag 15 is installed, is in a first position as shown and prevents the hood 40 from closing the cavity 30 (forming a mechanical stop for the hood 40), which alerts the user that the vacuum cleaner is not equipped with a vacuum bag 15. The game j shown between the cover 40 and a handle of the vacuum cleaner is important and indicates to the user that the vacuum cleaner is not in configuration to be used.

La figure 1b représente l'aspirateur de la figure 1a, avec un sac d'aspirateur 15 installé dans la cavité 30, le sac d'aspirateur 15 comprenant la cartonnette 10 montée sur le support de sac 20. Lors de son montage sur le support de sac 20, la cartonnette 10 a repoussé la butée 50 dans une deuxième position telle que représentée, et laisse le capot 40 fermer la cavité 30.The figure 1b represents the vacuum cleaner of the figure 1a with a vacuum bag 15 installed in the cavity 30, the vacuum bag 15 comprising the cardboard 10 mounted on the bag support 20. When mounted on the bag support 20, the cardboard 10 has pushed back the stop 50 in a second position as shown, and let the cover 40 close the cavity 30.

La figure 2 représente le support de sac 20 qui embarque la butée 50, et sur lequel est montée la cartonnette 10 du sac d'aspirateur 15 (non représenté ici pour des raisons de clarté).The figure 2 represents the bag support 20 which embeds the stop 50, and on which is mounted the cardboard 10 of the vacuum bag 15 (not shown here for the sake of clarity).

La cartonnette 10 présente une forme générale plane, et se monte sur le support de sac 20 en coulissant. A cet effet, la cartonnette 10 présente deux parties latérales 12a et 12b qui sont agencées sur un même plan (celui du corps de la cartonnette 10), et qui s'engagent dans des rainures du support de sac 20, jusqu'à ce que la cartonnette 10 arrive en butée sur le support de sac 20 comme représenté sur la figure 2.The cardboard 10 has a generally planar shape, and is mounted on the bag support 20 by sliding. For this purpose, the cardboard 10 has two lateral parts 12a and 12b which are arranged on the same plane (that of the body of the cardboard 10), and which engage in grooves of the bag support 20, until the cardboard 10 abuts on the bag support 20 as shown in FIG. figure 2 .

Par ailleurs, la cartonnette 10 comprend deux ergots 11a et 11b, et pendant le coulissement d'insertion de la cartonnette 10 dans le support de sac 20, les ergots 11a et 11b sont agencés de telle sorte qu'ils poussent la butée 50 pour la placer dans la deuxième position de la figure 1b, pour laisser le capot 40 fermer la cavité 30. La butée 50 est montée coulissante sur le support de sac 20, comme le montre la flèche, pour pouvoir passer de la première position vers la deuxième position.Furthermore, the cardboard 10 comprises two lugs 11a and 11b, and during the insertion sliding of the cardboard 10 into the bag support 20, the lugs 11a and 11b are arranged in such a way that they push the abutment 50 for the place in the second position of the figure 1b , to let the hood 40 close the cavity 30. The stop 50 is slidably mounted on the bag support 20, as shown by the arrow, to be able to move from the first position to the second position.

Les deux ergots 11a et 11b qui forment donc des moyens de commande de la butée 50 sont espacés l'un de l'autre pour entrer en contact avec la butée 50 au niveau de ses deux extrémités latérales, ce qui limite le risque de coincement ou arc-boutement lors du coulissement de la butée 50 dans le support de sac 20.The two lugs 11a and 11b which thus form control means of the stop 50 are spaced from each other to make contact with the abutment 50 at its two lateral ends, which limits the risk of jamming or bracing during the sliding of the stop 50 in the bag support 20.

De plus, comme le montre la figure 3, les ergots 11a et 11b sont en protubérance par rapport au plan formé par le corps de la cartonnette 10. Cela permet de dissocier la fonction de commande de la butée 50 de la fonction de coulissement de la cartonnette 10 dans le support de sac 20. En effet, les parties latérales 12a et 12b sont sur un même plan (celui de coulissement), et les ergots 11a et 11b sont eux en protubérance ou en saillie par rapport à ce plan. En conséquence, les interactions entre les fonctions sont limitées, et une dérive dimensionnelle ou une non-conformité sur les ergots 11a et 11b aura peu de conséquences sur les parties latérales 12a et 12b, et réciproquement.In addition, as shown in figure 3 , the lugs 11a and 11b are in protrusion with respect to the plane formed by the body of the cardboard 10. This makes it possible to dissociate the control function from the stop 50 of the sliding function of the cardboard 10 in the bag support 20. Indeed, the side portions 12a and 12b are on the same plane (that of sliding), and the lugs 11a and 11b are protruding or protruding from this plane. Consequently, the interactions between the functions are limited, and dimensional drift or nonconformity on the lugs 11a and 11b will have little effect on the lateral parts 12a and 12b, and vice versa.

En raison de la forme en trois dimensions de la cartonnette 10, on peut envisager de la réaliser par une opération de moulage, avec du polypropylène par exemple.Because of the three-dimensional shape of the cardboard 10, it can be envisaged to make it by a molding operation, with polypropylene for example.

La cartonnette 10 comprend un orifice 13 qui peut laisser passer un embout d'aspiration relié à un suceur d'aspirateur. Afin de limiter les fuites de poussières lors du changement de sac d'aspirateur 15, la cartonnette 10 peut être équipée d'un opercule amovible ou pivotant, avec des moyens élastiques pour assurer une fonction de fermeture automatique dès que l'embout d'aspiration n'est pas inséré dans l'orifice 13. Ces moyens élastiques peuvent être une lame flexible, un ressort ou une épingle.The cardboard 10 comprises an orifice 13 which can pass a suction nozzle connected to a vacuum nozzle. In order to limit the escape of dust during the change of the vacuum bag 15, the cardboard 10 can be equipped with a removable or pivoting lid, with elastic means to ensure an automatic closing function as soon as the suction nozzle is not inserted into the orifice 13. These resilient means may be a flexible blade, a spring or a pin.

On peut profiter du fait que la cartonnette 10 est réalisée par moulage pour surmouler les moyens élastiques directement dans la cartonnette 10. On peut même envisager de surmouler les moyens élastiques dans une partie plane de la cartonnette 10 qui sera rabattue et fixée (par soudage ultrason par exemple) sur le corps de la cartonnette 10 après moulage, pour mettre en tension les moyens élastiques par la même occasion.We can take advantage of the fact that the cardboard 10 is made by molding to overmold the elastic means directly in the cardboard 10. It is even possible to overmold the elastic means in a flat portion of the cardboard 10 which will be folded and fixed (by ultrasound welding for example) on the body of the cardboard 10 after molding, to tension the elastic means at the same time.

Une fois la cartonnette 10 en butée sur le support de sac 20 comme représenté à la figure 2, on peut prévoir une fonction anti retour, car la butée 50 coulissante est équipée de moyens de retour élastiques dans la première position, qui tendent à pousser constamment la cartonnette 10 hors du support de sac 20.Once the cardboard 10 abuts on the bag support 20 as shown in FIG. figure 2 it is possible to provide an anti-return function, since the sliding stop 50 is equipped with elastic return means in the first position, which tend to constantly push the cardboard 10 out of the bag support 20.

A cet effet, on peut implanter des ailes (non visibles sur les figures 2 et 3), en saillie sous la cartonnette 10, pour coopérer avec une partie déformable du support de sac 20, et assurer une fonction anti retour. Par exemple, les ailes en saillie sous la cartonnette peuvent déformer une ou plusieurs pattes élastiques du support de sac, et tout mouvement d'extraction nécessite une déformation supplémentaire, ce qui crée un effort anti retour.For this purpose, one can implant wings (not visible on the Figures 2 and 3 ), projecting under the cardboard 10, to cooperate with a deformable portion of the bag support 20, and provide an anti-return function. For example, the wings projecting under the cardboard may deform one or more elastic tabs of the bag support, and any extraction movement requires additional deformation, which creates an anti-return effort.

On comprendra que diverses modifications et/ou améliorations évidentes pour l'homme du métier peuvent être apportées au mode de réalisation de l'invention décrit dans la présente description sans sortir du cadre de l'invention défini par les revendications annexées.It will be understood that various modifications and / or improvements obvious to those skilled in the art can be made to the mode of embodiment of the invention described in the present description without departing from the scope of the invention defined by the appended claims.
