Description

ASPIRATEUR COMPORTANT UNE CONNEXION AMELIOREE AVEC UN VACUUM CLEANER WITH IMPROVED CONNECTION WITH
TUYAU D'ASPIRATIONSUCTION PIPE
DOMAINE TECHNIQUETECHNICAL AREA
La présente invention se rapporte à une connexion entre un tuyau d'aspiration, du type flexible et une unité d'aspiration mobile.The present invention relates to a connection between a suction hose, of the flexible type and a mobile suction unit.
La présente invention concerne principalement un aspirateur contenant un sac récupérateur de poussières obturable et dont l'obturation ou l'ouverture est commandée simultanément à un déblocage ou un blocage de moyens d'ouverture du bâti de l'aspirateur.The present invention relates mainly to a vacuum cleaner containing a closable dust collecting bag and the closing or opening of which is controlled simultaneously with the unlocking or blocking of means for opening the frame of the vacuum cleaner.
L'invention s'applique de manière générale à toute unité d'aspiration mobile du type aspirateur, déplaçable par l'utilisateur dans une zone à nettoyer et comportant un sac récupérateur de poussières, amovible et/ou jetable.The invention applies generally to any mobile suction unit of the vacuum cleaner type, movable by the user in a zone to be cleaned and comprising a dust-collecting bag, removable and / or disposable.
TECHNIQUE ANTERIEUREPRIOR ART
Il est déjà connu de réaliser des moyens d'obturation pour sacs, par exemple par l'intermédiaire du document WO-95/15109, lequel décrit un dispositif de connexion entre une buse d'un tuyau d'aspirateur et le bâti dudit aspirateur. Un tel dispositif permet de commander l'ouverture et la fermeture d'un sac récupérateur de poussières avec respectivement le verrouillage et le déverrouillage de la buse sur le bâti. Un tel système présente cependant un ensemble d'inconvénients et notamment, dans sa construction. La configuration particulière du moyen d'obturation actionné à l'aide de la buse ne permet pas la commande simultanée ou automatique d'autres organes. Il n'est ainsi pas possible de bloquer l'ouverture du bâti de l'aspirateur tant que le tuyau d'aspiration est connecté sur l'unité d'aspiration. Ceci constitue un désavantage non négligeable dans la mesure où l'utilisateur risque de détériorer les organes de fermeture de l'aspirateur.It is already known to produce sealing means for bags, for example by means of document WO-95/15109, which describes a connection device between a nozzle of a vacuum cleaner hose and the frame of said vacuum cleaner. Such a device makes it possible to control the opening and closing of a dust collecting bag with respectively the locking and unlocking of the nozzle on the frame. However, such a system has a number of drawbacks and in particular in its construction. The particular configuration of the closure means actuated by means of the nozzle does not allow simultaneous or automatic control of other members. It is therefore not possible to block the opening of the vacuum cleaner frame while the hose is connected to the suction unit. This constitutes a non-negligible disadvantage insofar as the user risks damaging the closing members of the vacuum cleaner.
EXPOSE DE L'INVENTIONSTATEMENT OF THE INVENTION
L'objet de la présente invention vise à remédier aux inconvénients de l'art antérieur et à réaliser de manière simple et facile à utiliser, un aspirateur dont le système de connexion du tuyau d'aspiration fonctionne de façon optimale en association avec un moyen d'obturation du sac récupérateur de poussières.The object of the present invention is to remedy the drawbacks of the prior art and to produce, in a simple and easy to use manner, a vacuum cleaner whose connection system of the suction pipe works optimally in combination with a means of '' dust bag closure.
L'objet de la présente invention vise également à réaliser un aspirateur dont le verrouillage du tuyau d'aspiration permet de commander simultanément le moyen d'obturation et un moyen de blocage permettant d'empêcher l'accès au volume interne de l'aspirateur.The object of the present invention also aims to produce a vacuum cleaner, the locking of the suction pipe makes it possible to simultaneously control the closure means and a blocking means making it possible to prevent access to the internal volume of the vacuum cleaner.

MEILLEURE MANIERE DE REALISER L'INVENTIONBEST WAY TO IMPLEMENT THE INVENTION
La figure 1 représente un sac 1 jetable d'aspirateur comportant une zone rigide 1a, laquelle contient un moyen d'obturation dudit sac 1, ainsi que l'agencement de ce moyen sur ledit sac 1. La zone rigide 1a, réalisée par exemple en matériau plastique et/ou cartonné, est constituée notamment d'un moyen de guidage 4 et d'un volet 5 d'obturation et d'ouverture du sac 1. Le moyen de guidage 4 est réalisé à partir d'un matériau rigide, par exemple cartonné, lequel comporte une perforation profilée 4a pour guider le volet 5 d'obturation et d'ouverture de l'entrée de remplissage du sac 1. Le volet 5 d'obturation est monté dans la zone rigide 1a, laquelle est pourvue de la perforation profilée 4a dont la forme et le contour réalisent le moyen de guidage 4 dans lequel se déplace le volet 5 d'obturation.FIG. 1 represents a disposable vacuum cleaner bag 1 comprising a rigid zone 1a, which contains a means for closing said bag 1, as well as the arrangement of this means on said bag 1. The rigid zone 1a, produced for example in plastic and / or cardboard material, consists in particular of a guide means 4 and a shutter 5 for closing and opening the bag 1. The guide means 4 is made from a rigid material, by cardboard example, which comprises a profiled perforation 4a to guide the shutter 5 for closing and opening the filling inlet of the bag 1. The shutter 5 for shutter is mounted in the rigid zone 1a, which is provided with the profiled perforation 4a, the shape and contour of which provide the guide means 4 in which the shutter 5 moves.
La perforation profilée 4a, ménagée dans le moyen de guidage 4, présente une forme d'oreille associée à un évidement 4b, le volet 5 d'obturation épousant partiellement par ses formes la perforation profilée 4a et présentant une surface inférieure à la perforation profilée 4a pour permettre la rotation dudit volet 5 d'obturation, lequel est entraîné par un moyen d'entraînement 10 solidaire d'une languette 5c associée au volet 5 dont la forme est conjuguée de l'évidement 4b. Ce dernier sert donc de logement à la languette 5c, de manière à pouvoir tourner dans l'évidement 4b et matérialiser ainsi un axe de rotation du volet 5. La perforation profilée 4a se présente donc sous une forme d'oreille virtuelle. Le volet 5 d'obturation, épousant partiellement par ses formes la perforation profilée 4a, présente également une forme d'oreille constituée d'un lobe plein 5a et d'un lobe perforé 5b. Le lobe plein 5a et le lobe perforé 5b se rattachent à la languette 5c de manière à ce que cette dernière puisse remplir le rôle d'un arbre de pivotement. L'arbre de pivotement ainsi réalisé par la languette 5c, est centré sur un axe x-x' schématisant également l'axe d'assemblage des différentes pièces constituant la zone rigide 1a du sac 1. L'évidement 4b est également centré sur l'axe x-x'.The profiled perforation 4a, formed in the guide means 4, has an ear shape associated with a recess 4b, the shutter 5 closing partially conforming by its shapes to the profiled perforation 4a and having a surface smaller than the profiled perforation 4a to allow the rotation of said shutter 5 which is driven by a drive means 10 integral a tongue 5c associated with the flap 5, the shape of which is combined with the recess 4b. The latter therefore serves as a housing for the tongue 5c, so as to be able to rotate in the recess 4b and thus materialize an axis of rotation of the flap 5. The profiled perforation 4a is therefore in the form of a virtual ear. The shutter 5, partially hugging its profiled perforation 4a, also has an ear shape consisting of a solid lobe 5a and a perforated lobe 5b. The solid lobe 5a and the perforated lobe 5b are attached to the tongue 5c so that the latter can fulfill the role of a pivot shaft. The pivot shaft thus produced by the tongue 5c, is centered on an axis xx 'also schematically showing the axis of assembly of the different parts constituting the rigid zone 1a of the bag 1. The recess 4b is also centered on the axis x-x '.
Le volet 5 est logé dans la perforation profilée 4a et les formes conjuguées, de la perforation 4a associée à l'évidement 4b et du volet 5 associé à la languette 5c, permettent au dit volet 5 d'être mobile par rotation dans le moyen de guidage 4 entre une position d'ouverture et une position de fermeture du sac 1 de remplissage. La forme et le contour de la perforation profilée 4a, associés à la configuration du volet 5 en forme d'oreille, permettent audit volet 5 d'être guidé tout au long de sa trajectoire, s'étendant entre une position d'ouverture et de fermeture de l'entrée de remplissage du sac 1. Selon une variante de réalisation du dispositif conforme à l'invention, le volet 5 est constitué d'un unique lobe plein 5a associé à la languette 5c. Le volet 5 d'obturation recouvre une partie de la surface de la perforation profilée 4a, de manière à permettre au dit volet 5 d'obturation de se déplacer dans ladite perforation profilée 4a. Ainsi dans la position d'ouverture du sac 1 , le lobe perforé 5b est en regard de l'entrée de remplissage du sac 1 et dans la position de fermeture du volet 5, le lobe plein 5a est en regard de l'entrée de remplissage du sac 1.The flap 5 is housed in the profiled perforation 4a and the conjugate forms, of the perforation 4a associated with the recess 4b and of the flap 5 associated with the tongue 5c, allow said flap 5 to be movable by rotation in the means of guide 4 between an open position and a closed position of the filling bag 1. The shape and contour of the profiled perforation 4a, associated with the configuration of the flap 5 in the form of an ear, allow said flap 5 to be guided along its trajectory, extending between an open position and closing the bag filling inlet 1. According to an alternative embodiment of the device according to the invention, the flap 5 consists of a single solid lobe 5a associated with the tongue 5c. The shutter 5 covers part of the surface of the profiled perforation 4a, so as to allow said shutter 5 to move in said profiled perforation 4a. Thus in the open position of the bag 1, the perforated lobe 5b is facing the filling inlet of the bag 1 and in the closed position of the flap 5, the full lobe 5a is facing the filling inlet from bag 1.
La zone rigide 1a du sac 1 est constituée d'un assemblage formant une structure sandwich incluant une plaque de fixation 2 solidaire du sac 1 et munie d'un orifice 2a, le moyen de guidage 4 présentant la perforation profilée 4a dans laquelle est logé le volet 5 d'obturation ainsi qu'une feuille rigide frontale 6 dans laquelle est ménagée une ouverture 6a de manière à enserrer le volet 5 d'obturation dans la perforation profilée 4a. La zone rigide 1a, constituée de plaques ou lamelles assemblées successivement permet d'obtenir une rigidité et une flexibilité optimale pour solidariser et désolidariser le sac 1 du bâti de l'aspirateur. La plaque de fixation 2, réalisée de préférence en un matériau rigide constitue avec l'orifice 2a l'entrée de remplissage du sac 1. Une telle réalisation préférentielle rend la zone rigide 1a, et en particulier le dispositif d'obturation, particulièrement solide et résistant aux chocs. Il n'existe en effet aucune possibilité d'accéder au volet 5 de manière à le tordre ou à le déformer malencontreusement. La feuille rigide frontale 6 comporte une ouverture 6a centrée sur l'orifice 2a. La feuille rigide frontale 6 est par exemple collée ou agrafée sur la plaque de fixation 2 de manière à solidariser l'ensemble de la zone rigide 1 a avec le sac 1. L'utilisation de tout autre moyen de fixation de la feuille frontale rigide 6 sur la plaque de fixation 2 est envisageable.The rigid zone 1a of the bag 1 consists of an assembly forming a sandwich structure including a fixing plate 2 secured to the bag 1 and provided an orifice 2a, the guide means 4 having the profiled perforation 4a in which the shutter 5 is housed as well as a front rigid sheet 6 in which an opening 6a is formed so as to enclose the shutter 5 of obturation in the profiled perforation 4a. The rigid zone 1a, consisting of plates or strips assembled successively, makes it possible to obtain an optimal rigidity and flexibility for securing and detaching the bag 1 from the frame of the vacuum cleaner. The fixing plate 2, preferably made of a rigid material constitutes with the orifice 2a the filling inlet of the bag 1. Such a preferred embodiment makes the rigid zone 1a, and in particular the closure device, particularly solid and impact resistant. There is indeed no possibility of accessing the flap 5 so as to twist or deform it inadvertently. The front rigid sheet 6 has an opening 6a centered on the orifice 2a. The rigid front sheet 6 is for example glued or stapled to the fixing plate 2 so as to secure the whole of the rigid zone 1 a with the bag 1. The use of any other means of fixing the rigid front sheet 6 on the fixing plate 2 is possible.
Avantageusement, la zone rigide 1a comprend une membrane d'étanchéité 3 dans laquelle est ménagé un trou 3a. La membrane d'étanchéité 3 est disposée entre la plaque de fixation 2 et le moyen de guidage 4. Le trou 3a est de préférence réalisé par deux incisions perpendiculaires centrées sur l'orifice 2a, sur l'ouverture 6a et sur le lobe perforé 5b lorsque le volet 5 est en position d'ouverture du sac 1. L'utilisation d'une membrane d'étanchéité 3 est particulièrement avantageuse pour rattraper le jeu et par conséquent les défauts d'étanchéité lorsqu'un tuyau d'aspirateur est en communication avec le sac 1 à travers l'orifice 2a. La plaque de fixation 2, la membrane d'étanchéité 3 et la feuille rigide frontale 6 présentent respectivement un perçage 2b, 3b et 6b lesquels permettent au moyen d'entraînement 10, lequel est solidaire de la languette 5c de traverser cette dernière et de lui transmettre un mouvement de rotation. Le moyen d'entraînement 10 est commandé par un organe de commande 11 actionné par exemple de l'extérieur du bâti 13 de l'aspirateur. Le moyen d'entraînement 10 est solidaire de la languette 5c par l'intermédiaire d'une entaille 5d ménagée dans ladite languette 5c. Le bâti 13 constitue, bien entendu, un boîtier ou une enveloppe externe d'un ensemble d'aspiration comportant notamment des organes d'aspiration du type moteur/ventilateur. De manière avantageuse l'entaille 5d peut être remplacée par deux entailles croisées perpendiculaires. Le moyen d'entraînement 10 présente une forme complémentaire de l'entaille 5d. L'ensemble, constitué de la plaque de fixation 2, de la membrane d'étanchéité 3, du moyen de guidage 4, du volet 5 et de la feuille rigide frontale 6, représenté à la figure 1 , constitue ainsi la zone rigide 1a du sac 1.Advantageously, the rigid zone 1a comprises a sealing membrane 3 in which a hole 3a is formed. The sealing membrane 3 is disposed between the fixing plate 2 and the guide means 4. The hole 3a is preferably made by two perpendicular incisions centered on the orifice 2a, on the opening 6a and on the perforated lobe 5b when the flap 5 is in the open position of the bag 1. The use of a sealing membrane 3 is particularly advantageous to make up for the play and therefore the sealing faults when a vacuum cleaner hose is in communication with the bag 1 through the opening 2a. The fixing plate 2, the sealing membrane 3 and the front rigid sheet 6 respectively have a bore 2b, 3b and 6b which allow the drive means 10, which is integral with the tongue 5c to pass through the latter and from it transmit a rotational movement. The drive means 10 is controlled by a control member 11 actuated for example from the outside of the frame 13 of the vacuum cleaner. The drive means 10 is integral with the tongue 5c by means of a notch 5d formed in said tongue 5c. The frame 13 constitutes, of course, a housing or an external envelope of a suction assembly comprising in particular suction members of the motor / fan type. Advantageously, the notch 5d can be replaced by two perpendicular crossed notches. The drive means 10 has a shape complementary to the notch 5d. The assembly, consisting of the fixing plate 2, the sealing membrane 3, the guide means 4, the flap 5 and the front rigid sheet 6, represented in FIG. 1, thus constitutes the rigid zone 1a of the bag 1.
La figure 2 représente un dispositif de connexion entre un tuyau d'aspirateur et un sac 1 récupérateur de poussières agencé sur le bâti 13 d'un aspirateur, ledit dispositif comportant une buse 20 de fixation formant l'extrémité du tuyau d'aspiration, des moyens de verrouillage de la buse 20 sur le bâti 13 ainsi que le volet 5 d'obturation du sac 1 déplaçable entre une position d'ouverture et une position de fermeture. Le dispositif comporte l'organe de commande 11 , et des moyens de coopération agencés sur l'organe de commande 11 et sur la buse 20 pour coopérer lorsque le volet 5 d'obturation est dans la position d'ouverture de façon à verrouiller la buse 20 sur le bâti 13. Les moyens de coopération sont par exemple constitués de moyens du type mâle/femelle.2 shows a connection device between a vacuum cleaner hose and a dust collecting bag 1 arranged on the frame 13 of a vacuum cleaner, said device comprising a fixing nozzle 20 forming the end of the suction hose, means for locking the nozzle 20 on the frame 13 as well as the shutter 5 for closing the bag 1 movable between an open position and a closed position. The device comprises the control member 11, and cooperation means arranged on the control member 11 and on the nozzle 20 to cooperate when the shutter 5 is in the open position so as to lock the nozzle 20 on the frame 13. The cooperation means for example consist of means of the male / female type.
Les moyens de coopération sont par exemple constitués d'un ergot 21 agencé sur la buse 20 et d'un dégagement 11b ménagé dans une partie de l'organe de commande 11 , ledit ergot 21 se logeant dans le dégagement 11b lors de l'opération de verrouillage de la buse 20 sur le bâti 13. Le verrouillage ne peut être obtenu que lorsque l'ergot 21 est introduit dans le dégagement 11b ou lorsqu'il passe à travers le dégagement 11b. Une telle coopération n'est possible que lorsque l'organe de commande 11 , mobile par rotation, se trouve dans une position angulaire bien déterminée. Cette dernière correspond à la position d'ouverture du moyen d'obturation du sac 1. Une rotation de l'organe de commande 11 correspond à une rotation du moyen d'entraînement 10 lequel est solidaire mécaniquement de l'organe de commande 11.The cooperation means consist for example of a lug 21 arranged on the nozzle 20 and a recess 11b formed in a part of the control member 11, said lug 21 being housed in the recess 11b during the operation for locking the nozzle 20 on the frame 13. The locking can only be obtained when the lug 21 is introduced into the clearance 11b or when it passes through the clearance 11b. Such cooperation is not possible that when the control member 11, movable by rotation, is in a well-defined angular position. The latter corresponds to the open position of the means for closing the bag 1. A rotation of the control member 11 corresponds to a rotation of the drive means 10 which is mechanically integral with the control member 11.
Avantageusement, la buse 20 est connectée à un tuyau flexible constituant le tuyau de l'aspirateur lequel est en rotation libre par rapport à la buse 20 par l'intermédiaire de tout moyen connu. Ainsi l'utilisateur de l'aspirateur ne se trouve nullement gêné par le verrouillage fixe de la buse 20 sur le bâti 13. L'organe de commande 11 est ainsi monté mobile par rotation pour fermer ou ouvrir le sac 1 d'une part et par translation éventuellement pour désolidariser le sac 1 du bâti 13.Advantageously, the nozzle 20 is connected to a flexible hose constituting the hose of the vacuum cleaner which is in free rotation relative to the nozzle 20 via any known means. Thus the user of the vacuum cleaner is in no way hampered by the fixed locking of the nozzle 20 on the frame 13. The control member 11 is thus mounted movable by rotation to close or open the bag 1 on the one hand and by translation if necessary to separate the bag 1 from the frame 13.
Selon une variante additionnelle de réalisation du dispositif conforme à l'invention et représenté aux figures 3a, 3b et 3c, ce dernier comporte une buse 20 munie d'au moins un éperon 22 sur sa périphérie, un support de buse 30 monté mobile en rotation sur le bâti 13 et comportant d'une part au moins une fente 31 dans laquelle se déplace l'éperon 22 et d'autre part un doigt 32 coopérant avec le moyen d'entraînement 10. L'éperon 22 s'étend vers l'extérieur de la fente 31 pour prendre appui sur un système de butée 15 en forme d'escalier à deux niveaux 16, 17 pour guider le verrouillage de la buse 20 sur le bâti 13 en utilisant quatre positions distinctes pour l'éperon 22.According to an additional embodiment of the device according to the invention and shown in Figures 3a, 3b and 3c, the latter comprises a nozzle 20 provided with at least one spur 22 on its periphery, a nozzle support 30 mounted movable in rotation on the frame 13 and comprising on the one hand at least one slot 31 in which the spur 22 moves and on the other hand a finger 32 cooperating with the drive means 10. The spur 22 extends towards the outside of the slot 31 to rest on a stop system 15 in the form of a two-level staircase 16, 17 to guide the locking of the nozzle 20 on the frame 13 using four distinct positions for the spur 22.
Le moyen d'entraînement 10 coopère avec le doigt 32 par l'intermédiaire d'une came 10b, représentée à la figure 4 et agencée solidairement sur ledit moyen d'entraînement 10. La came 10b est agencée sur le moyen d'entraînement 10 dans l'espace libre situé entre le bâti 13 et la zone rigide 1a. Ainsi, le doigt 32 fait basculer la came 10b lors d'une rotation de la buse 20 correspondant soit à une obturation soit à une ouverture du sac 1 par le volet 5. La figure 3b représente le support de buse 30, muni de la fente 31 dans laquelle se déplace l'éperon 22 et du doigt 32 pilotant l'organe de commande 11.The drive means 10 cooperates with the finger 32 by means of a cam 10b, shown in FIG. 4 and arranged integrally on said drive means 10. The cam 10b is arranged on the drive means 10 in the free space located between the frame 13 and the rigid zone 1a. Thus, the finger 32 causes the cam 10b to tilt during a rotation of the nozzle 20 corresponding either to a closure or to an opening of the bag 1 by the flap 5. FIG. 3b shows the nozzle support 30, provided with the slot 31 in which the spur 22 moves and the finger 32 driving the control member 11.
La figure 3c représente le système de butée 15 présentant deux niveaux distincts 16 et 17 permettant à la buse 20 d'occuper successivement plusieurs positions lors de la mise en place de ladite buse 20 sur le support de buse 30. La première position correspond à un appui de l'éperon 22 sur le premier niveau 16 du système de butée 15 après un premier enfoncement E1 de la buse 20, la deuxième position correspondant à un positionnement de l'éperon 22 au delà du premier niveau 16 après une première rotation R1 dans le plan d'extension du premier niveau 16, la troisième position correspondant à un appui de l'éperon 22 sur le deuxième niveau 17 après un deuxième enfoncement E2, la quatrième position correspondant au verrouillage de l'éperon 22 sur le bâti 13 après une deuxième rotation R2 dans le plan d'extension du deuxième niveau 17. Le système de butée 15, solidaire du bâti 13 et s'étendant au voisinage de la périphérie du support de buse 30, présente des niveaux 16 et 17 suffisamment étendus le long d'une périphérie interne 19 du bâti 13 de manière à permettre successivement l'ouverture du sac 1 lors de la première rotation R1 et le verrouillage de la buse 20 sur le bâti 13 lors de la deuxième rotation R2. En outre le premier enfoncement E1 permet de loger l'éperon 22 dans la fente 31 et le deuxième enfoncement E2 correspond à l'introduction de la buse 20 dans le sac 1 de manière à traverser la membrane d'étanchéité 3.FIG. 3c shows the stop system 15 having two distinct levels 16 and 17 allowing the nozzle 20 to successively occupy several positions during the positioning of said nozzle 20 on the nozzle support 30. The first position corresponds to a support of the spur 22 on the first level 16 of the stop system 15 after a first depression E1 of the nozzle 20, the second position corresponding to a positioning of the spur 22 beyond the first level 16 after a first rotation R1 in the extension plane of the first level 16, the third position corresponding to a support of the spur 22 on the second level 17 after a second depression E2, the fourth position corresponding to the locking of the spur 22 on the frame 13 after a second rotation R2 in the extension plane of the second level 17. The stop system 15, integral with the frame 13 and extending in the vicinity of the periphery of the nozzle support 30, has d es levels 16 and 17 sufficiently extended along an internal periphery 19 of the frame 13 so as to allow successively the opening of the bag 1 during the first rotation R1 and the locking of the nozzle 20 on the frame 13 during the second rotation R2. Furthermore, the first depression E1 makes it possible to house the spur 22 in the slot 31 and the second depression E2 corresponds to the introduction of the nozzle 20 into the bag 1 so as to pass through the sealing membrane 3.
La figure 3d représente le schéma fonctionnel de la mise en place de la buse 20 sur le bâti 13. En schématisant les quatre étapes successives du verrouillage incluant le premier enfoncement E1 , la première rotation R1 , le deuxième enfoncement E2 ainsi que la deuxième rotation R2.Figure 3d shows the block diagram of the establishment of the nozzle 20 on the frame 13. By diagramming the four successive stages of locking including the first depression E1, the first rotation R1, the second depression E2 as well as the second rotation R2 .
Avantageusement le dispositif conforme à l'invention comprend un bossage 18 agencé sur le bâti 13 en regard du deuxième niveau 17 de la butéeAdvantageously, the device according to the invention comprises a boss 18 arranged on the frame 13 opposite the second level 17 of the stop.
15, ledit éperon 22 est logé entre le bossage 18 et le deuxième niveau 17 dans la position de verrouillage de la buse 20 sur le bâti 13. Ainsi la buse 20 ne peut être désolidarisée du bâti 13. Le déverrouiilage ou la désolidarisation de la buse 20 du bâti 13 s'effectue de manière inverse au verrouillage en dégageant l'éperon 22 du bossage 18 contre lequel l'éperon 22 est en appui dans la position de verrouillage.15, said spur 22 is housed between the boss 18 and the second level 17 in the locking position of the nozzle 20 on the frame 13. Thus the nozzle 20 cannot be separated from the frame 13. The unlocking or uncoupling of the nozzle 20 from the frame 13 is carried out in reverse to locking by releasing the spur 22 of the boss 18 against which the spur 22 is supported in the locked position.
Ainsi, les moyens de coopération permettent d'actionner automatiquement l'ouverture et la fermeture du sac 1 avec respectivement l'opération de verrouillage et de déverrouillage de la buse 20 sur le bâti 13.Thus, the cooperation means make it possible to automatically activate the opening and closing of the bag 1 with the locking and unlocking operation of the nozzle 20 on the frame 13 respectively.
Selon une autre variante du dispositif conforme à l'invention, le bossage 18 est remplacé par une rampe inclinée par rapport à l'horizontale et agencée sur la périphérie interne 19 du bâti 13.According to another variant of the device according to the invention, the boss 18 is replaced by a ramp inclined relative to the horizontal and arranged on the internal periphery 19 of the frame 13.
Selon une autre variante de réalisation du dispositif conforme à l'invention, la butée 15 est constituée d'une rainure profilée ménagée dans le bâti 13. L'éperon 22 se déplace ainsi dans la rainure profilée et ne peut en aucune manière être dégagé de ladite rainure profilée tant qu'il n'est pas dans la première position correspondant au premier enfoncement E1. Le dispositif ainsi conçu interdit à la buse 20 de se désolidariser du bâti 13 tant que le volet 5 n'est pas en position fermée.According to another alternative embodiment of the device according to the invention, the stop 15 consists of a profiled groove formed in the frame 13. The spur 22 thus moves in the profiled groove and cannot in any way be released from said profiled groove as long as it is not in the first position corresponding to the first depression E1. The device thus designed prohibits the nozzle 20 from detaching from the frame 13 as long as the flap 5 is not in the closed position.
Avantageusement le dispositif conforme à l'invention le bâti 13 comporte une deuxième butée 15 symétrique par rapport à la première pour assurer une meilleure stabilité de l'ensemble verrouillé. Dans cette variante de réalisation, le système de butée 15 correspond à un système du type baïonnetteAdvantageously, the device according to the invention, the frame 13 comprises a second stop 15 symmetrical with respect to the first to ensure better stability of the locked assembly. In this alternative embodiment, the stop system 15 corresponds to a bayonet type system
Les figures 5, 6 et 7 représentent une autre variante de réalisation de l'aspirateur conforme à l'invention.Figures 5, 6 and 7 show another alternative embodiment of the vacuum cleaner according to the invention.
La figure 5 représente ainsi un assemblage déjà effectué de la buse 20 sur le bâti 13 de l'aspirateur. Le maintien de la buse 20 est obtenu notamment à l'aide de portions flexibles 121 , 122 présentant à leur extrémité des rebords 121a, 122a venant s'engager dans une rainure correspondante ménagée dans le bâti 13. La coopération entre la buse 20 lors de sa mise en place sur le bâti avec l'organe de commande 11 permet d'actionner un moyen de blocage 102 pour empêcher l'ouverture du bâti 13 tant que la buse 20 demeure verrouillée sur l'aspirateur.FIG. 5 thus represents an assembly already carried out of the nozzle 20 on the frame 13 of the vacuum cleaner. The maintenance of the nozzle 20 is obtained in particular by means of flexible portions 121, 122 having at their ends rims 121a, 122a coming to engage in a corresponding groove made in the frame 13. The cooperation between the nozzle 20 during its positioning on the frame with the control member 11 makes it possible to actuate a locking means 102 to prevent the opening of the frame 13 as long as the nozzle 20 remains locked on the vacuum cleaner.
Avantageusement une partie du bâti 13 réalise un capot 13d susceptible de refermer un espace interne 13b contenant le sac 1 et de verrouiller la buse 20. Le capot 13d est maintenu en position ou libéré à l'aide d'un clapet de fixation 103 pivotant. Ce dernier est de préférence monté sur un axe de rotation 104 et contre un ressort de rappel 105 du type lame flexible. Le clapet de fixation 103 présente à l'une de ses extrémités un ergot 103a venant en appui contre un bord d'appui 13a ménagé sur une paroi 13c de l'aspirateur. Dans une telle position, le capot 13d sur lequel est fixé la buse 20 se trouve solidarisé avec le restant de l'unité d'aspiration et plus particulièrement avec la partie complémentaire au capot 13d contenant par exemple le moteur, le ventilateur et d'autres éléments constitutifs de l'unité d'aspiration. La libération du capot 13d est obtenue par une pression sur le clapet de fixation 103 de façon à le faire pivoter autour de son axe de rotation 104 contre le ressort de rappel 105. L'ergot 103a se trouve ainsi dégagé du bord d'appui 13a et le capot 13d peut être dégagé pour rendre accessible le volume intérieur de l'aspirateur. Le capot 13d est monté pivotant sur l'unité d'aspiration à l'aide de moyens d'articulation du type charnières, non représentés aux figures.Advantageously, part of the frame 13 produces a cover 13d capable of closing an internal space 13b containing the bag 1 and of locking the nozzle 20. The cover 13d is held in position or released by means of a pivoting fixing valve 103. The latter is preferably mounted on an axis of rotation 104 and against a return spring 105 of the flexible blade type. The fixing valve 103 has at one of its ends a lug 103a bearing against a support edge 13a formed on a wall 13c of the vacuum cleaner. In such a position, the cover 13d on which the nozzle 20 is fixed is secured to the remainder of the suction unit and more particularly to the part complementary to the cover 13d containing for example the motor, the fan and other components of the suction unit. The release of the cover 13d is obtained by pressing the fixing valve 103 so as to make it pivot about its axis of rotation 104 against the return spring 105. The lug 103a is thus released from the bearing edge 13a and the cover 13d can be released to make the interior volume of the vacuum cleaner accessible. The cover 13d is pivotally mounted on the suction unit by means of articulation means of the hinge type, not shown in the figures.
Selon une variante de réalisation de l'aspirateur conforme à l'invention, le capot 13d peut également être amovible. Il est évident qu'une libération du capotAccording to an alternative embodiment of the vacuum cleaner according to the invention, the cover 13d can also be removable. Obviously a release of the hood
13d n'est possible que lorsque la buse 20 se trouve déverrouillée dudit capot 13d. En effet, le moyen de blocage 102 empêche tout actionnement du clapet de fixation 103 lorsque la buse 20 est verrouillée sur le capot 13d tel que cela est représenté à la figure 5. Le moyen de blocage 102 est donc susceptible de venir en appui contre le clapet de fixation 103 pour empêcher la libération du capot 13d. Le moyen de blocage 102 est solidaire de l'organe de commande 11 et du moyen d'entraînement 10. Ainsi tout actionnement de l'organe de commande 11 par l'intermédiaire de la buse 20 entraîne automatiquement un actionnement du moyen de blocage 102. Ceci est possible grâce aux moyens de coopération. Ces derniers permettent par l'intermédiaire du verrouillage de la buse 20 de commander simultanément l'ouverture du volet 5 et le blocage du clapet de fixation 103 empêchant ainsi l'ouverture du capot 13d. L'organe de commande 11 est ainsi monté mobile en rotation et comporte le moyen d'entraînement 10 venant s'engager dans une partie du volet 5 pour déplacer ce dernier par rotation.13d is only possible when the nozzle 20 is unlocked from said cover 13d. Indeed, the locking means 102 prevents any actuation of the fixing valve 103 when the nozzle 20 is locked on the cover 13d as is shown in Figure 5. The locking means 102 is therefore capable of coming into abutment against the fixing valve 103 to prevent the release of the cover 13d. The locking means 102 is integral with the control member 11 and the drive means 10. Thus any actuation of the control member 11 via the nozzle 20 automatically causes actuation of the locking means 102. This is possible thanks to the means of cooperation. The latter make it possible, by means of the locking of the nozzle 20, to simultaneously control the opening of the flap 5 and the blocking of the fixing valve 103 thus preventing the opening of the cover 13d. The control member 11 is thus mounted mobile in rotation and comprises the drive means 10 coming to engage in a part of the flap 5 to move the latter by rotation.
Le sac 1 récupérateur de poussières est disposé dans l'aspirateur de préférence à l'aide d'un support de sac sur lequel il est fixé. Selon une variante de réalisation d'un tel montage et conformément à l'invention, le sac 1 peut également être monté sur le capot 13d et sur le moyen d'entraînement 10 avant la fermeture de l'unité d'aspiration par ledit capot 13d.The dust collection bag 1 is preferably placed in the vacuum cleaner using a bag support on which it is fixed. According to an alternative embodiment of such an assembly and in accordance with the invention, the bag 1 can also be mounted on the cover 13d and on the drive means 10 before the suction unit is closed by said cover 13d .
Selon l'exemple de réalisation représenté notamment à la figure 6 les moyens de coopération sont réalisés avec des dentelures 101 solidaires de la buse 20 et venant s'engager dans un bras denté 100 solidaire de l'organe de commande 11 et du moyen d'entraînement 10 pour obtenir une liaison mécanique du type engrenage. Le moyen de blocage se trouve disposé diamétralement opposé au bras denté 100.According to the embodiment shown in particular in Figure 6 the cooperation means are made with serrations 101 secured to the nozzle 20 and engaging in a toothed arm 100 secured to the control member 11 and the means of drive 10 to obtain a mechanical connection of the gear type. The locking means is placed diametrically opposite the toothed arm 100.
La figure 6 représente une section, sensiblement selon la direction F montrée à la figure 5 d'une part, et dans une situation dans laquelle le clapet de fixation 103 peut être actionné d'autre part. Ce dernier n'est effectivement plus bloqué par le moyen de blocage 102. Une telle situation correspond par conséquent à l'obturation du sac. Dans une telle variante de réalisation de l'aspirateur conforme à l'invention, l'organe de commande 11 n'est pas accessible directement par l'utilisateur. Par ailleurs, les portions flexibles 121 , 122 sont susceptibles de s'engager dans des rainures de guidage ménagées dans le capot 13d. Les rainures de guidage présentent des dimensions différentes de façon à n'avoir qu'une seule possibilité d'engagement de la buse 20 dans le capot 13d, c'est à dire qu'une seule orientation. Cette dernière permettra en effet d'obtenir un engagement des dentelures 101 avec le bras denté 100.6 shows a section, substantially in the direction F shown in Figure 5 on the one hand, and in a situation in which the fixing valve 103 can be actuated on the other hand. The latter is effectively no longer blocked by the locking means 102. Such a situation therefore corresponds to the closing of the bag. In such an alternative embodiment of the vacuum cleaner according to the invention, the control member 11 is not directly accessible by the user. Furthermore, the flexible portions 121, 122 are capable of engaging in guide grooves formed in the cover 13d. The guide grooves have different dimensions so as to have only one possibility of engagement of the nozzle 20 in the cover 13d, that is to say only one orientation. The latter will in fact make it possible to obtain engagement of the serrations 101 with the toothed arm 100.
La figure 7 permet de schématiser le fonctionnement et la coopération des différents éléments lors du montage de la buse 20 sur le bâti 13. Le sac 1 présente une ouverture d'aspiration fermée et est monté dans l'aspirateur ou sur le capot 13d de manière à permettre l'engagement du moyen d'entraînement 10 dans une partie du volet 5. Le capot 13d est ensuite fixé sur l'unité d'aspiration à l'aide du clapet de fixation 103. L'utilisateur engage ensuite la buse 20 et plus précisément les rebords de maintien dans les rainures de guidage selon une direction E3 sensiblement normale au capot 13d. Lors de cet engagement transversal selon une direction E3, les dentelures 101 viennent s'engrener avec les dents du bras denté 100 et les rebords 121a, 122a de maintien viennent en butée contre des arrêts spécifiques prévus dans le bâti 13. L'utilisateur procède ensuite à une rotation de la buse 20 selon une direction R3 schématisée aux figures 6 et 7. La rotation de la buse 20 se poursuit jusqu'à une position de butée complémentaire, et à pour effet de faire pivoter en sens inverse le moyen d'entraînement 10 ainsi que le moyen de blocage 102. Ce dernier vient par conséquent buter contre le clapet de fixation 103 et empêche l'ouverture du capot 13d. En outre, la rotation du moyen d'entraînement 10 à pour conséquence de déplacer le volet d'obturation 5 et de dégager l'orifice d'accès du sac 1. L'utilisateur transmet ensuite un deuxième mouvement de translation E4 à la buse 20 parallèlement à la direction E3. Ce dernier déplacement de la buse 20 a pour conséquence d'engager l'extrémité de ladite buse 20 dans l'orifice de remplissage du sac 1 ou contre la membrane d'étanchéité 3 d'une part, et de faire pénétrer les rebords de maintien 121a, 122a dans des logements spécifiques prévus dans le bâti 13, et ce à l'aide des forces de rappel élastiques générés par les portions flexibles 121 et 122. Ce dernier mouvement de translation E4 a pour conséquence d'interdire à la buse 20 de tourner en rotation d'une part et d'être retirée du capot 13d ou du bâti 13 d'autre part.FIG. 7 makes it possible to schematize the operation and the cooperation of the different elements during the mounting of the nozzle 20 on the frame 13. The bag 1 has a closed suction opening and is mounted in the vacuum cleaner or on the cover 13d so to allow the engagement of the drive means 10 in a part of the flap 5. The cover 13d is then fixed to the suction unit by means of the fixing valve 103. The user then engages the nozzle 20 and more precisely the retaining flanges in the guide grooves in a direction E3 substantially normal to the cover 13d. During this transverse engagement in a direction E3, the serrations 101 mesh with the teeth of the toothed arm 100 and the retaining flanges 121a, 122a come into abutment against specific stops provided in the frame 13. The user then proceeds to a rotation of the nozzle 20 in a direction R3 shown diagrammatically in FIGS. 6 and 7. The rotation of the nozzle 20 continues until a complementary stop position, and has the effect of rotating the drive means in the opposite direction 10 as well as the locking means 102. The latter therefore abuts against the fixing valve 103 and prevents the opening of the cover 13d. In addition, the rotation of the drive means 10 has the consequence of displacing the shutter 5 and clearing the access orifice of the bag 1. The user then transmits a second translational movement E4 to the nozzle 20 parallel to direction E3. This last movement of the nozzle 20 has the consequence of engaging the end of said nozzle 20 in the filling orifice of the bag 1 or against the sealing membrane 3 on the one hand, and penetrate the retaining flanges 121a, 122a into specific housings provided in the frame 13, and this using elastic return forces generated by the flexible portions 121 and 122. This last translational movement E4 has the consequence of prohibit the nozzle 20 from rotating on the one hand and from being removed from the cover 13d or from the frame 13 on the other hand.
Avantageusement la buse 20 et le bâti 13 comportent des éléments de contact 110, 111 pour établir des connexions électriques entre le tuyau d'aspiration et le bâti 13 avec l'opération de verrouillage de la buse 20 sur le bâti 13. En effet des éléments de contact électriques en l'occurrence des parties cylindriques et tubulaires s'engageant les unes dans les autres sont prévues dans le bâti 13 et dans la buse 20. De telles opérations d'engagement se produisent lors du second mouvement de translation de la buse 20, à savoir selon la direction E4. Les connexions électriques ainsi effectuées contribuent également à bloquer en rotation la buse 20 lorsque cette dernière est définitivement engagée dans le capot 13d. Différentes fonctions ou fonctionnements commandés électriquement peuvent être commandés directement à partir du tuyau d'aspiration.Advantageously, the nozzle 20 and the frame 13 comprise contact elements 110, 111 for establishing electrical connections between the suction pipe and the frame 13 with the operation of locking the nozzle 20 on the frame 13. Indeed elements electric contact in this case cylindrical and tubular parts engaging one another are provided in the frame 13 and in the nozzle 20. Such engagement operations occur during the second translational movement of the nozzle 20 , namely according to direction E4. The electrical connections thus made also contribute to blocking in rotation the nozzle 20 when the latter is definitively engaged in the cover 13d. Different electrically controlled functions or functions can be controlled directly from the suction pipe.
Après une opération de nettoyage l'utilisateur dégage la buse 20 de l'aspirateur en opérant de la façon détaillée ci-après. Il exerce une pression sur les portions flexibles 121 , 122 de façon à libérer les rebords de maintien 121a et 122a et tire sur la buse 20 selon une direction opposée à la direction E4 pour rencontrer en fin de course une butée. L'utilisateur procède ensuite à une rotation inverse au sens de rotation R3 ce qui devient possible dans la mesure où notamment les éléments de contact électriques sont déconnectés, pour finalement retirer la buse 20 selon une direction opposée à la direction E3. L'aspirateur se trouve ainsi dans un état de fin d'utilisation dans lequel le volet 5 obture complètement le sac 1 récupérateur de poussières et dans lequel le moyen de blocage 102 se trouve dégagé de l'appui contre le clapet de fixation 103 rendant ainsi possible l'ouverture du capot 13d. Le sac 1 récupérateur de poussières peut ainsi être évacué ou tout simplement laissé à l'intérieur de l'aspirateur dans l'attente d'une nouvelle utilisation. Le tuyau d'aspiration se trouve donc séparé du bâti 13.After a cleaning operation, the user releases the nozzle 20 from the vacuum cleaner, operating in the manner detailed below. It exerts pressure on the flexible portions 121, 122 so as to release the retaining flanges 121a and 122a and pulls on the nozzle 20 in a direction opposite to the direction E4 to meet a stop at the end of the race. The user then proceeds to reverse rotation in the direction of rotation R3 which becomes possible insofar as in particular the electrical contact elements are disconnected, to finally withdraw the nozzle 20 in a direction opposite to the direction E3. The vacuum cleaner is thus in a state of end of use in which the flap 5 completely closes the bag 1 dust collector and in which the blocking means 102 is released from the support against the fixing valve 103 thus making possible opening of the cover 13d. The bag 1 recuperator of dust can thus be removed or simply left inside the vacuum cleaner while waiting for a new use. The suction pipe is therefore separated from the frame 13.
Un avantage de l'aspirateur conforme à l'invention réside dans l'obtention d'une fermeture automatique du sac 1 par le déverrouillage de la buse 20.An advantage of the vacuum cleaner according to the invention lies in obtaining an automatic closure of the bag 1 by unlocking the nozzle 20.
Un autre avantage de l'aspirateur conforme à l'invention est obtenu par l'absence de contact direct entre l'utilisateur et le sac 1 rempli de poussières après une utilisation de l'aspirateur.Another advantage of the vacuum cleaner according to the invention is obtained by the absence of direct contact between the user and the bag 1 filled with dust after use of the vacuum cleaner.
Un avantage supplémentaire de l'aspirateur conforme à l'invention réside dans l'obtention d'une plus grande hygiène, dans la mesure ou le tuyau d'aspiration ne peut être séparé du bâti 13 tant que le sac 1 n'est pas obturé. En outre le capot 13d de l'aspirateur ne peut être ouvert tant que le tuyau d'aspiration demeure fixé sur le bâti 13. Une telle conception présente l'avantage de ne pas détériorer les charnières d'articulation du capot 13d sous l'effet d'efforts de torsion, ou tout simplement d'encombrer l'utilisateur avec un sous- ensemble constitué du tuyau, du capot 13d et éventuellement du sac 1 lorsque ce dernier est solidaire dudit capot 13d.An additional advantage of the vacuum cleaner according to the invention lies in obtaining greater hygiene, since the suction pipe cannot be separated from the frame 13 until the bag 1 is closed. . In addition, the cover 13d of the vacuum cleaner cannot be opened as long as the suction pipe remains fixed on the frame 13. Such a design has the advantage of not damaging the hinges of articulation of the cover 13d under the effect torsional forces, or simply to clutter the user with a subassembly consisting of the pipe, the cover 13d and possibly the bag 1 when the latter is integral with said cover 13d.
