DOMAINE TECHNIQUETECHNICAL AREA
La présente invention se rapport à un dispositif de connexion entre un tuyau d'aspiration, du type flexible et une unité d'aspiration mobile.The present invention relates to a connection device between a suction hose, of the flexible type and a mobile suction unit.
La présente invention concerne également un dispositif d'obturation et d'éjection de sac jetable d'aspirateur ledit sac étant fixé, lors de l'opération de nettoyage sur une partie du bâti dudit aspirateur.The present invention also relates to a device for closing and ejecting a disposable vacuum cleaner bag, said bag being fixed, during the cleaning operation, to a part of the frame of said vacuum cleaner.
L'invention s'applique de manière générale à toute unité d'aspiration mobile du type aspirateur, déplaçable par 1'utilisateur dans une zone à nettoyer et comportant un sac récupérateur de poussières, amovible et jetable.The invention generally applies to any mobile suction unit of the vacuum cleaner type, movable by the user in a zone to be cleaned and comprising a removable and disposable dust collecting bag.
TECHNIQUE ANTERIEUREPRIOR ART
L'état de la technique dans ce domaine est constitué, par exemple par le document US-A-3.335.744, lequel décrit un système fixe et central d'aspiration, connecté à un tuyau d'aspiration. Le système d'aspiration comporte un clapet d'obturation agencé sur une ouverture d'aspiration et escamotable élastiquement lors de la mise en place du tuyau d'aspiration. Le système ainsi décrit concerne une installation centrale associée à un ensemble de conduits d'aspiration répartis dans les sols et/ou les murs de bâtiment.The state of the art in this field consists, for example, of document US-A-3,335,744, which describes a fixed and central suction system, connected to a suction pipe. The suction system comprises a shutter valve arranged on a suction opening and retractable elastically when the suction pipe is put in place. The system thus described relates to a central installation associated with a set of suction ducts distributed in the floors and / or walls of the building.
II est également connu de réaliser des moyens d'obturation pour sacs, par exemple par l'intermédiaire du document FR-A-932.776, lequel décrit un sac muni d'un moyen d'obturation. Ce dernier pivote entre une position d'ouverture et une position de fermeture de 1 'entrée de remplissage du sac, à l'aide d'un système mécanique constitué d'un axe de pivotement, d'un moyen de rappel élastique ainsi que d'une pièce faisant office de butée pour le moyen d'obturation, agencés sur une plaquette rigide du sac. Un tel système présente un ensemble d'inconvénients et notamment, dans sa construction, pour laquelle un nombre de pièces distinctes important est nécessaire, générant ainsi un coût de fabrication élevé.It is also known to produce sealing means for bags, for example by means of document FR-A-932.776, which describes a bag provided with sealing means. The latter rotates between a position opening and closing position of the bag filling inlet, using a mechanical system consisting of a pivot axis, an elastic return means as well as a part acting as stop for the closure means, arranged on a rigid plate of the bag. Such a system has a set of drawbacks and in particular, in its construction, for which a large number of separate parts is necessary, thus generating a high manufacturing cost.
En outre, l'agencement du système et plus particulièrement du moyen d'obturation sur la plaquette rigide, de manière accessible, fragilise ledit système, et la configuration particulière du moyen d'obturation ne permet pas son actionnement simple et/ou automatique avec un organe de commande indépendant.In addition, the arrangement of the system and more particularly of the closure means on the rigid plate, in an accessible manner, weakens said system, and the particular configuration of the closure means does not allow its simple and / or automatic actuation with a independent control unit.
L'objet de la présente invention vise à remédier aux inconvénients de 1'art antérieur et à réaliser de manière simple, pas coûteuse, 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 aims to remedy the drawbacks of the prior art and to provide a simple, inexpensive, and easy to use, vacuum cleaner whose connection system of the suction pipe works optimally in combination with a means of sealing the dust collection bag.
L'objet de la présente invention consiste à fournir un dispositif d'obturation de sac d'aspirateur que l'utilisateur peut actionner sans entrer en contact directement avec ledit sac lors de l'opération de l'obturation.The object of the present invention is to provide a vacuum bag closure device which the user can operate without coming into direct contact with said bag during the closure operation.
Un autre objet de la présente invention vise à fournir à l'utilisateur d'aspirateurs un dispositif d'éjection dudit sac du bâti de l'aspirateur, simple et peu contraignant.Another object of the present invention is to provide the user of vacuum cleaners with a device for ejecting said bag from the frame of the vacuum cleaner, simple and not very restrictive.
Un autre objet de l'invention consiste à utiliser un moyen d'obturation du sac d'aspirateur occupant un espace limité, facilement réalisable, à faible coût et pouvant être disposé en position d'ouverture ou de fermeture au gré de l'utilisateur. Un autre objet de l'invention vise à fournir un dispositif de sécurité visant à interdire la fixation du tuyau d'aspirateur sur le bâti de 1'aspirateur lorsque le sac est obturé.Another object of the invention consists in using a means for closing the vacuum cleaner bag occupying a limited space, easily achievable, at low cost and which can be disposed in the open or closed position at the discretion of the user. Another object of the invention is to provide a safety device intended to prevent the attachment of the vacuum cleaner hose to the frame of the vacuum cleaner when the bag is closed.
Un objet supplémentaire de l'invention vise à fournir un dispositif de fermeture automatique de sacs d'aspirateurs.Another object of the invention is to provide a device for automatically closing vacuum cleaner bags.
EXPOSE DE L ' INVENTIONSTATEMENT OF THE INVENTION

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 la, laquelle contient un moyen d'obturation dudit sac 1, ainsi que 1'agencement de ce moyen sur ledit sac 1. La zone rigide la, 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 la, 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 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 for guiding 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 moves the shutter 5.
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 1'évidement 4b. Ce dernier sert donc de logement à la languette 5c, de manière à pouvoir tourner dans l'evidement 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. La languette 5c est de préférence centrée sur une ligne médiane ou de symétrie, non représentée aux figures, de 1'oreille représentant le lobe plein 5a et le lobe perforé 5b. L'evidement 4b est ainsi également centré sur une ligne médiane ou de symétrie, non représenté aux figures, de l'oreille virtuelle définie par la perforation profilée 4a. L'arbre de pivotement ainsi réalisé par la languette 5c, est centré sur un axe x-x' schématisant également 1 'axe d'assemblage des différentes pièces constituant la zone rigide la du sac 1. L'evidement 4b est également centré sur l'axe x-x' . Avantageusement la languette 5c, le lobe plein 5a et le lobe perforé 5b sont réalisés en une seule pièce, laquelle est obtenue par exemple par découpage dans une feuille cartonnée.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 with a tongue 5c associated with the shutter 5, the shape of which is conjugated 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 tongue 5c is preferably centered on a center line or line of symmetry, not shown in the figures, of the ear representing the solid lobe 5a and the perforated lobe 5b. The recess 4b is thus also centered on a center line or line of symmetry, not shown in the figures, of the virtual ear defined by the profiled perforation 4a. The pivot shaft thus produced by the tongue 5c, is centered on an axis xx ′ also schematically representing the axis of assembly of the different parts constituting the rigid zone la of the bag 1. The recess 4b is also centered on the axis xx '. Advantageously, the tongue 5c, the solid lobe 5a and the perforated lobe 5b are produced in a single piece, which is obtained for example by cutting from a cardboard sheet.
Le volet 5 est logé dans la perforation profilée 4a et les formes conjuguées, de la perforation 4a associée à l'evidement 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. La perforation profilée 4a, et/ou 1'évidement 4b sont également utilisés comme butées extrêmes contre lesquelles le volet 5 vient s'appuyer dans l'une ou l'autre de sa position d'ouverture ou de fermeture. 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 1'entrée de remplissage du sac 1 et dans la position de fermeture du volet 5, le lobe plein 5a est en regard de 1'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 guide means 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. The profiled perforation 4a, and / or the recess 4b are also used as extreme stops against which the flap 5 comes to bear in one or the other of its position d 'opening or closing. 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 la 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 la, 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 la, 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. Avantageusement, le volet 5 est réalisé à partir du moyen de guidage 4 en utilisant une portion de matière soustraite par tout moyen connu audit moyen de guidage 4, lors de la réalisation la perforation profilée 4a. Le volet 5 est ensuite découpé de manière à être mobile par rotation dans la perforation profilée 4a et à disposer en regard de l'orifice 2a, le lobe perforé 5b ou le lobe plein 5a pour respectivement ouvrir ou fermer 1'accès au sac 1. 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 la 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 integral with the bag 1 and provided with an orifice 2a, the guide means 4 having the profiled perforation 4a in which is housed the shutter 5 and a rigid front sheet 6 in which is formed an opening 6a so as to enclose the shutter 5 in the profiled perforation 4a. The rigid zone 1a, consisting of plates or strips assembled successively, makes it possible to obtain optimum 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 for the bag 1. Such a preferred embodiment makes the rigid area 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. Advantageously, the flap 5 is produced from the guide means 4 using a portion of material subtracted by any known means from said guide means 4, during the production of the profiled perforation 4a. The flap 5 is then cut so as to be movable by rotation in the profiled perforation 4a and to have opposite the orifice 2a, the perforated lobe 5b or the full lobe 5a to respectively open or close the access to the bag 1. 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 1a with the bag 1. The use of any other means of fixing the rigid front sheet 6 on the fixing plate 2 is possible.
Préférentiellement, l'épaisseur du volet 5 est légèrement inférieure à l'épaisseur du moyen de guidage 4 de manière à faciliter sa rotation dans 1 'espace libre délimité par la plaque de fixation 2, la feuille rigide frontale 6 ainsi que par une surface définie par 1 'épaisseur du moyen de guidage 4 et le contour de la perforation profilée 4a.Preferably, the thickness of the flap 5 is slightly less than the thickness of the guide means 4 so as to facilitate its rotation in one free space delimited by the fixing plate 2, the front rigid sheet 6 as well as by a defined surface. by the thickness of the guide means 4 and the contour of the profiled perforation 4a.
Avantageusement, la zone rigide la 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.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 have respectively 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 to transmit a rotational movement to it.
Le moyen d'entraînement 10 est commandé par un organe de commande 11 actionné de l'extérieur du bâti 13 de l'aspirateur, ledit moyen d'entraînement 10 étant 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 la du sac 1.The drive means 10 is controlled by a control member 11 actuated from outside the frame 13 of the vacuum cleaner, said drive means 10 being secured to 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 la bag 1.
L'organe de commande 11 est monté mobile en translation au dessus de la zone rigide la pour exercer une déformation sur ladite zone rigide la permettant de désolidariser le sac 1 du bâti 13 de l'aspirateur. La zone rigide la présente une flexibilité suffisante pour se dégager d'un rebord 14 et d'une rainure 14b lorsque l'utilisateur exerce une pression sur l'organe de commande 11. Avantageusement l'organe de commande 11 revient en position initiale par translation après l'éjection du sac 1 par l'intermédiaire d'un ressort lia agencé dans ledit organe de commande 11.The control member 11 is mounted movable in translation above the rigid zone 1a to exert a deformation on said rigid zone allowing it to separate the bag 1 from the frame 13 of the vacuum cleaner. The rigid zone 1a has sufficient flexibility to disengage from a flange 14 and a groove 14b when the user exerts pressure on the control member 11. Advantageously the control member 11 returns to the initial position by translation after the bag 1 has been ejected via a spring 11a arranged in said control member 11.
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 1 '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 du sac 1 de remplissage. 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 et permettre ainsi le verrouillage de la buse 20 sur le bâti 13. Les moyens de coopération sont par exemple constitués de moyens du type mâle/femelle. Préférentiellement, le dispositif comporte un moyen mâle agencé sur la buse 20 et un moyen femelle agencé sur 1 'organe de commande 11. Selon une variante de réalisation du dispositif conforme à l'invention, ce dernier comporte un moyen mâle agencé sur l'organe de commande 11 et un moyen femelle agencé sur la buse 20.2 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 and the flap 5 for closing the bag 1 movable between an open position and a closed position of the filling bag 1. 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 and thus allow the locking of the nozzle 20 on the frame 13. The cooperation means consist for example of means of the male / female type. Preferably, the device comprises a male means arranged on the nozzle 20 and a female means arranged on the control member 11. According to an alternative embodiment of the device according to the invention, the latter comprises a male means arranged on the member 11 and a female means arranged on the nozzle 20.
De manière avantageuse les moyens de coopération sont 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. Le 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 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.Advantageously, the cooperation means consist 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 locking operation. The locking of the nozzle 20 on the frame 13. The locking can only be obtained when the lug 21 is introduced into the clearance 11b or passes through the clearance 11b. Such cooperation is only possible 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 1 ' aspirateur lequel est en rotation libre par rapport à la buse 20 par 1'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 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 by means of 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 to separate the bag 1 from the frame 13.
Selon une variante de réalisation du dispositif de connexion conforme à l'invention, les moyens de coopération entre la buse 20 et l'organe de commande 11, sont réalisés par le volet d'obturation 5 directement, en empêchant l'opération de verrouillage de la buse 20. Cette dernière vient en butée contre le volet d'obturation 5 lorsque ce dernier est en position de fermeture du sac 1.According to an alternative embodiment of the connection device according to the invention, the means of cooperation between the nozzle 20 and the control member 11 are produced by the shutter 5 directly, preventing the locking operation from the nozzle 20. The latter abuts against the shutter 5 when the latter is in the closed position of the bag 1.
Selon une variante additionnelle de réalisation du dispositif conforme à l'invention et représenté aux figures 3, 3a et 3b, ce dernier comporte une buse 20 munie d'au moins un éperon 22 sur sa périphérie, un support de buse 30 monté mobile par 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 de l'organe de commande 11, ledit éperon 22 s'étendant 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 3, 3a and 3b, the latter comprises a nozzle 20 provided with at least one spur 22 on its periphery, a nozzle support 30 mounted movable by 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 of the control member 11, said spur 22 extending outwards from the slot 31 to bear 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 separate 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 de manière solidaire sur ledit moyen d'entraînement 10. La came 10b est agencée sur le moyen d'entraînement 10 dans 1'espace libre situé entre le bâti 13 et la zone rigide la. 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 moyen d'obturation.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 situated between the frame 13 and the rigid zone 1a. Thus, the finger 32 causes the cam 10b to tilt during rotation of the nozzle 20 corresponding either to a shutter or to an opening of the bag 1 by the shutter means.
La figure 3a 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.FIG. 3a 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 3b 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 1 'éperon 22 sur le premier niveau 16 du système de butée 15 après un premier enfoncement El de la buse 20, la deuxième position correspondant à un positionnement de 1 'éperon 22 au delà du premier niveau 16 après une première rotation RI 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 1 'ouverture du sac 1 lors de la première rotation RI et le verrouillage de la buse 20 sur le bâti 13 lors de la deuxième rotation R2. En outre le premier enfoncement El permet de loger 1'éperon 22 dans la fente 31 et le deuxième enfoncement E2 correspond à 1'introduction de la buse 20 dans le sac 1 de manière à traverser la membrane d'étanchéité 3.FIG. 3b represents the stop system 15 having two distinct levels 16 and 17 allowing the nozzle 20 to occupy successively 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 of the nozzle 20, the second position corresponding to a positioning of the spur 22 beyond the first level 16 after a first rotation RI 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 levels 16 and 17 sufficiently extended along an internal periphery 19 of the frame 13 so as to pe rmit successively the opening of the bag 1 during the first rotation RI and the locking of the nozzle 20 on the frame 13 during the second rotation R2. Furthermore, the first recess E1 accommodates the spur 22 in the slot 31 and the second recess E2 corresponds to the introduction of the nozzle 20 into the bag 1 so as to pass through the sealing membrane 3.
Dans ce mode de réalisation, la mise en oeuvre de moyens tels qu'un ergot 21 et un dégagement 11b n'est plus indispensable.In this embodiment, the implementation of means such as a lug 21 and a clearance 11b is no longer essential.
La figure 3c 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 renfoncement El, la première rotation RI, le deuxième renfoncement E2 ainsi que la deuxième rotation R2.FIG. 3c represents the functional diagram of the positioning of the nozzle 20 on the frame 13. By diagramming the four successive stages of the locking including the first recess El, the first rotation RI, the second recess 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 butée 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 déverrouillage 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.Advantageously, the device according to the invention comprises a boss 18 arranged on the frame 13 opposite the second level 17 of the stop 15, said spur 22 is housed between the boss 18 and the second level 17 in the position for locking the nozzle 20 on the frame 13. Thus the nozzle 20 cannot be separated from the frame 13. The unlocking or detaching of the nozzle 20 from the frame 13 is carried out in reverse to locking by releasing the spur 22 from the boss 18 against which the spur 22 bears in the locked position.
Ainsi, les moyens de coopération permettent d'actionner automatiquement 1'ouverture et la fermeture du sac 1 avec respectivement 1'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 respectively with the locking and unlocking operation of the nozzle 20 on the frame 13.
Selon une variante avantageuse du dispositif conforme à l'invention, le dégagement 11b débouche sur un espace libre dans lequel se déplace une tige non représentée aux figures et solidaire du support de buse 30 après le deuxième renfoncement E2. Ainsi une face lie de l'organe de commande 11 vient en surplomb et réalise une butée pour la tige lorsque l'utilisateur exerce une pression sur l'organe de commande 11 lorsque la buse 20 est verrouillée sur le bâti 13 correspondant à une position d'une ouverture du moyen d'obturation du sac 1. Ce dernier ne peut alors être désolidarisé du bâti 13.According to an advantageous variant of the device according to the invention, the clearance 11b opens onto a free space in which moves a rod not shown in the figures and secured to the nozzle support 30 after the second recess E2. Thus a face of the control member 11 overhangs and achieves a stop for the rod when the user exerts pressure on the control member 11 when the nozzle 20 is locked on the frame 13 corresponding to a position d an opening of the means for closing the bag 1. The latter cannot then be separated from the frame 13.
Selon une autre variante de réalisation du dispositif conforme à l'invention, un appui complémentaire peut être ménagé sur le bâti 13 empêchant toute translation de 1'organe de commande 11 lorsque le moyen d'obturation du sac 1 est en position d'ouverture.According to another alternative embodiment of the device according to the invention, additional support can be provided on the frame 13 preventing any translation of the control member 11 when the means for closing the bag 1 is in the open position.
Selon une autre variante du dispositif conforme à l'invention, le bossage 18 est remplacé par une rampe inclinée par rapport à 1 '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 with respect 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 El. Le dispositif ainsi conçu interdit à la buse 20 de se désolidariser du bâti 13 tant que le moyen ou volet 5 d'obturation du sac 1 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 made in the frame 13. The spur 22 is 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 means or flap 5 for closing the bag 1 is not in the closed position.
Avantageusement le dispositif conforme à 1 ' invention le bâti 13 comporte une deuxième butée 15 symétrique par rapport à la première pour assurer une meilleure stabilité de l'ensemble verrouillé, lequel est constitué de la buse 20 et du bâti 13. 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, which consists of the nozzle 20 and the frame 13. In this alternative embodiment , the stop system 15 corresponds to a bayonet type system
Les figures 2, 3, 3a, 3b, 3c et 4 schématisent ainsi un dispositif de connexion entre une unité d'aspiration et un tuyau d'aspiration, constitué de la buse 20, des moyens de verrouillage de la buse 20 sur le bâti 13 ainsi que des moyens de coopération permettant à la buse 20 de coopérer avec l'organe de commande 11, de telle sorte que le verrouillage de ladite buse 20 est possible dès que le volet 5 est dans sa position d'ouverture.Figures 2, 3, 3a, 3b, 3c and 4 thus schematize a connection device between a suction unit and a suction pipe, consisting of the nozzle 20, means for locking the nozzle 20 on the frame 13 as well as cooperation means allowing the nozzle 20 to cooperate with the control member 11, so that the locking of said nozzle 20 is possible as soon as the flap 5 is in its open position.
Le fonctionnement du dispositif conforme à 1 ' invention est illustré dans ce qui suit par les opération suivantes.The operation of the device according to the invention is illustrated in the following by the following operations.
L'utilisateur commence par fixer le sac 1 à 1'intérieur du bâti 13 par l'intermédiaire du rebord 14 et de la rainureThe user begins by fixing the bag 1 inside the frame 13 via the flange 14 and the groove
14b, de façon à engager le moyen d'entraînement 10 dans l'entaille 5d. L'utilisateur fait ensuite tourner l'organe de commande 11 de manière à positionner le volet 5 dans sa position d'ouverture. La buse 20 peut alors être fixée, sur le bâti 13. Lorsque le sac 1 est rempli, l'utilisateur sépare la buse 20 du bâti 13, tourne le volet 5 dans sa position d'obturation à l'aide de l'organe de commande 11 et sépare la partie du bâti 13 sur laquelle est fixé le sac 1 du reste de l'unité d'aspiration. L'utilisateur peut alors désolidariser le sac 1 de la partie du bâti 13 amovible, par exemple au dessus d'une poubelle, par une simple pression sur l'organe de commande 1114b, so as to engage the drive means 10 in the notch 5d. The user then rotates the control member 11 so as to position the flap 5 in its open position. The nozzle 20 can then be fixed, on the frame 13. When the bag 1 is filled, the user separates the nozzle 20 from the frame 13, turns the shutter 5 to its closed position using the control 11 and separates the part of the frame 13 on which the bag 1 is fixed from the rest of the suction unit. The user can then separate the bag 1 from the part of the removable frame 13, for example above a trash can, by a simple pressure on the member 11
Un autre fonctionnement du dispositif conforme à l'invention et obtenu par une variante de réalisation. L'utilisateur fixe le sac 1 initialement fermé par exemple, sur le bâti 13. L'engagement de la buse 20 dans le bâti 13, par l'intermédiaire d'éperons 22 et du support de buse 30, et selon des mouvements respectifs El, RI, E2 et R2, permet respectivement d'ouvrir 1'entrée de remplissage du sac 1, et de verrouiller la buse 20 sur le bâti 13. Lorsque l'utilisateur sépare la buse 20 du bâti 13, le volet 5 du sac 1 se trouve automatiquement dans sa position de fermeture. L'organe de commande 11 est ensuite utilisé uniquement pour séparer la partie rigide la dudit bâti 13, par un mouvement de translation de l'organe de commande 11. Une simplification pourrait dans ce cas être envisagée, et laquelle consisterait à utiliser le moyen d'entraînement 10, associé à la came 10b, comme organe de commande 11 à l'intérieur du bâti 13. L'utilisateur devrait alors séparer le sac 1 du bâti 13 par ses propres moyens et notamment par une torsion de la zone rigide la.Another operation of the device according to the invention and obtained by an alternative embodiment. The user fixes the bag 1 initially closed, for example, on the frame 13. The engagement of the nozzle 20 in the frame 13, by means of spurs 22 and of the nozzle support 30, and according to respective movements El , RI, E2 and R2, allow respectively to open the filling inlet of the bag 1, and to lock the nozzle 20 on the frame 13. When the user separates the nozzle 20 from the frame 13, the flap 5 of the bag 1 is automatically in its closed position. The control member 11 is then used only to separate the rigid part la from said frame 13, by a translational movement of the control member 11. A simplification could in this case be envisaged, and which would consist in using the means d 'drive 10, associated with the cam 10b, as a control member 11 inside the frame 13. The user should then separate the bag 1 from the frame 13 by his own means and in particular by twisting the rigid zone 1a.
Un avantage du dispositif conforme à 1'invention réside dans 1'obtention d'une fermeture automatique du sac 1 par le déverrouillage de la buse 20 ou par actionnement de 1 'organe de commande 11 directement par l'utilisateur.An advantage of the device according to the invention lies in obtaining an automatic closure of the bag 1 by unlocking the nozzle 20 or by actuating the control member 11 directly by the user.
Un autre avantage du dispositif conforme à l'invention est obtenu par 1'absence de contact direct entre l'utilisateur et le sac 1 rempli de poussières après une utilisation de l'aspirateur. L'éjection se faisant par simple pression sur l'organe de commande 11.Another advantage of the device 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. The ejection is done by simple pressure on the control member 11.
Un avantage supplémentaire du sac 1 conforme à l'invention réside dans la réalisation d'un système d'obturation, comprenant un volet 5 pivotant d'une part et dépourvu d'axe de rotation pour ledit volet 5. POSSIBILITES D 'APPLICATION INDUSTRIELLEAn additional advantage of the bag 1 according to the invention lies in the production of a closure system, comprising a flap 5 pivoting on the one hand and devoid of a rotation axis for said flap 5.
