Description
La présente invention concerne de manière générale un dispositif d'accouplement d'un conduit d'aspiration pour aspirateur.The present invention relates generally to a device for coupling a suction duct for vacuum cleaner.
Il est connu dans l'art antérieur des dispositifs d'accouplement de conduits d'aspirateur tel que celui décrit dans le document
Un but de la présente invention est de répondre aux inconvénients de l'art antérieur mentionnés ci-dessus et en particulier, tout d'abord, de proposer un dispositif d'accouplement fiable, économique à construire et présentant une bonne ergonomie d'utilisation.An object of the present invention is to meet the drawbacks of the prior art mentioned above and in particular, firstly, to provide a reliable coupling device, economical to build and having good ergonomics of use.
Pour cela un premier aspect de l'invention concerne un dispositif d'accouplement d'un conduit d'aspiration, le dispositif comprenant :
- une pièce femelle et
- une pièce mâle agencée pour s'insérer dans la pièce femelle jusqu'à une position d'accouplement, la pièce femelle comprenant au moins une butée axiale femelle, la pièce mâle comprenant au moins une butée axiale mâle agencée pour s'engager et entrer en butée avec la butée axiale femelle et empêcher un mouvement de retrait de la pièce mâle depuis la position d'accouplement,
- des moyens élastiques liés à l'une de la butée axiale femelle ou de la butée axiale mâle pour la rendre mobile et agencés pour permettre l'engagement et la mise en butée automatique de la butée axiale mâle avec la butée axiale femelle lors d'un mouvement d'insertion de la pièce mâle dans la pièce femelle jusqu'à la position d'accouplement,
- au moins une bague rotative comprenant une came angulaire, agencée pour être pivotée depuis une première position où les moyens élastiques sont libres, vers une deuxième position où les moyens élastiques sont contraints par la came angulaire, de sorte que lorsque la pièce mâle est en position d'accouplement, la butée axiale femelle et la butée axiale mâle sont désengagées l'une de l'autre, permettant ainsi un retrait de la pièce mâle hors de la pièce femelle. Le dispositif d'accouplement selon la mise en oeuvre ci-dessus est aisé à commander, puisque le déverrouillage se fait en pivotant une unique bague rotative : l'utilisateur n'a qu'une interface à commander, suivant un seul mouvement pour accoupler la pièce mâle (le mouvement d'insertion selon une direction axiale du conduit d'aspiration) et un seul mouvement pour retirer la pièce mâle (le pivotement de la bague rotative). De plus, le dispositif compte un nombre de composants réduit, ce qui limite les coûts de fabrication.
- a female part and
- a male part arranged to fit into the female part to a coupling position, the female part comprising at least one female axial stop, the male part comprising at least one male axial stop arranged to engage and enter stop with female axial stop and prevent withdrawal movement of the male part from the coupling position,
- elastic means connected to one of the female axial abutment or the male axial abutment to make it movable and arranged to allow the engagement and the automatic abutment of the male axial abutment with the axial abutment female during a movement of insertion of the male part in the female part to the coupling position,
- at least one rotating ring comprising an angular cam, arranged to be pivoted from a first position where the elastic means are free, to a second position where the elastic means are constrained by the angular cam, so that when the male piece is in position coupling, the female axial stop and the male axial stop are disengaged from each other, thus allowing removal of the male piece out of the female part. The coupling device according to the implementation above is easy to control, since the unlocking is done by pivoting a single rotating ring: the user has only one interface to control, in a single movement to couple the male piece (the insertion movement in an axial direction of the suction duct) and a single movement to remove the male piece (the pivoting of the rotating ring). In addition, the device has a reduced number of components, which limits manufacturing costs.
Selon un mode de réalisation, la bague rotative est agencée pour pouvoir :
- pivoter de la première position vers la deuxième position selon un premier sens de rotation,
- pivoter de la première position vers une troisième position selon un deuxième sens de rotation opposé au premier sens de rotation,
- pivoting from the first position to the second position in a first direction of rotation,
- pivoting from the first position to a third position in a second direction of rotation opposite to the first direction of rotation,
Selon un mode de réalisation, la pièce mâle et/ou la pièce femelle sont chacune formée par un assemblage de plusieurs composants. Pour faciliter la conception, il peut être intéressant de former des assemblages.According to one embodiment, the male part and / or the female part are each formed by an assembly of several components. To facilitate the design, it can be interesting to form assemblies.
Selon un mode de réalisation, le dispositif comprend des moyens d'éjection agencés pour être commandés par la bague rotative lorsqu'elle est pivotée, et pour créer un effort axial de retrait sur la pièce mâle à partir d'un couple de rotation exercé par la bague rotative, de sorte à provoquer un mouvement de retrait de la pièce mâle depuis la position d'accouplement. L'ergonomie est améliorée car la seule action de déverrouillage provoque l'éjection de la pièce mâle. On peut envisager d'utiliser une came ou un levier pour transformer le couple et/ou mouvement de rotation de la bague rotative en effort et/ou mouvement axial de la pièce mâle.According to one embodiment, the device comprises ejection means arranged to be controlled by the rotating ring when it is pivoted, and to create an axial withdrawal force on the male part from a torque exerted by the rotating ring, so as to cause a withdrawal movement of the male part from the coupling position. The ergonomics are improved because the only unlocking action causes the ejection of the male part. It is conceivable to use a cam or lever to transform the torque and / or rotational movement of the rotating ring into force and / or axial movement of the male part.
Selon un mode de réalisation, la pièce mâle et la pièce femelle comprennent chacune au moins une butée angulaire agencée pour s'engager l'une avec l'autre lorsque la pièce mâle est en position d'accouplement, de sorte à bloquer une rotation relative entre la pièce femelle et la pièce mâle en position d'accouplement. L'utilisateur n'a pas à exercer de contre couple sur le dispositif ou l'aspirateur pour maintenir ces derniers : les butées angulaires assurent cette fonction. Le dispositif peut donc être commandé d'une seule main par exemple, en agissant uniquement sur la bague rotative.According to one embodiment, the male piece and the female piece each comprise at least one angular abutment arranged to engage with each other when the male piece is in the coupling position, so as to block a relative rotation. between the female part and the male part in the coupling position. The user does not have to exert against torque on the device or the vacuum cleaner to maintain the latter: the angular stops provide this function. The device can be controlled by one hand for example, by acting only on the rotating ring.
Selon un mode de réalisation, les butées angulaires comprennent les moyens d'éjection. Le dispositif est simplifié en cumulant les fonctions sur les mêmes pièces.According to one embodiment, the angular stops comprise the ejection means. The device is simplified by combining the functions on the same parts.
Selon un mode de réalisation, les butées angulaires comprennent des dents avec des pentes, sur la pièce mâle et sur la pièce femelle, agencées pour s'imbriquer les unes dans les autres de sorte à offrir le blocage en rotation lorsque la pièce mâle est dans la position d'accouplement, et à provoquer un mouvement axial de retrait de la pièce mâle lors d'un glissement entre les pentes, provoqué par le couple exercé par la bague rotative. Les pentes des dents, qui sont coniques, provoquent un mouvement axial sous l'effet du couple dans une direction tangentielle. On reproduit ainsi une came qui transforme le mouvement et/ou couple rotatif exercé sur la butée axiale liée aux moyens élastiques par la bague rotative en mouvement et/ou effort axial de la pièce mâle.According to one embodiment, the angular stops comprise teeth with slopes, on the male part and on the female part, arranged to fit into each other so as to offer the locking in rotation when the male part is in the coupling position, and to cause an axial movement of withdrawal of the male part during a sliding between the slopes, caused by the torque exerted by the ring press. The slopes of the teeth, which are tapered, cause axial movement under the effect of torque in a tangential direction. A cam is thus reproduced which transforms the rotary movement and / or torque exerted on the axial stop connected to the elastic means by the rotating ring in movement and / or axial force of the male piece.
Selon un mode de réalisation, le dispositif comprend une piste de guidage conique agencée pour déplacer ladite une de la butée axiale femelle ou de la butée axiale mâle liée aux moyens élastiques, lors du mouvement d'insertion de la pièce mâle dans la pièce femelle jusqu'à la position d'accouplement et l'engagement entre la butée axiale femelle et la butée axiale mâle, et ledit mouvement de retrait provoqué par lesdits moyens d'éjection est suffisant pour positionner l'une de la butée axiale femelle ou de la butée axiale mâle liée aux moyens élastiques en regard de la piste de guidage conique. Le retrait de la pièce mâle se fait en deux temps : le mouvement de retrait provoqué par les moyens d'éjection a pour effet de placer la butée axiale (mâle ou femelle) liée aux moyens élastiques face à la piste de guidage conique, et les moyens élastiques encore partiellement contraints vont créer un effort sur la piste de guidage conique pour finir d'éjecter la pièce mâle.According to one embodiment, the device comprises a conical guide track arranged to move said one of the female axial abutment or the male axial abutment linked to the elastic means, during the insertion movement of the male part in the female part until at the coupling position and the engagement between the female axial stop and the male axial stop, and said withdrawal movement caused by said ejection means is sufficient to position one of the female axial abutment or abutment axial male linked to the elastic means facing the conical guide track. The removal of the male part is done in two steps: the withdrawal movement caused by the ejection means has the effect of placing the axial stop (male or female) linked to the elastic means facing the conical guide track, and the resilient means still partially constrained will create a force on the conical guide track to finish ejecting the male part.
Selon un mode de réalisation, ladite une de la butée axiale mâle ou de la butée axiale femelle liée aux moyens élastiques comprend un ergot d'actionnement agencé pour être commandé par la bague rotative, et un ergot de clipsage avec une première portion agencée pour glisser sur la piste de guidage conique lors du mouvement d'insertion et une deuxième portion agencée pour s'engager avec l'autre que ladite une de la butée axiale mâle ou de la butée axiale femelle liée aux moyens élastiques.According to one embodiment, said one of the male axial abutment or the female axial abutment linked to the elastic means comprises an actuating pin arranged to be controlled by the rotary ring, and a clipping lug with a first portion arranged for sliding on the conical guide track during the insertion movement and a second portion arranged to engage with each other that said one of the male axial stop or the female axial stop connected to the elastic means.
Selon un mode de réalisation, l'une de la butée axiale femelle ou de la butée axiale mâle liée aux moyens élastiques est formée par trois surfaces planes mobiles, les moyens élastiques étant constitués par trois pattes élastiques, et l'autre de la butée axiale femelle ou de la butée axiale mâle est une surface plane formant une couronne autour du conduit d'aspiration. On peut envisager d'agencer les trois surfaces planes mobiles à 120° pour augmenter la stabilité de l'assemblage.According to one embodiment, one of the female axial abutment or the male axial abutment linked to the elastic means is formed by three movable flat surfaces, the elastic means being constituted by three elastic tabs, and the other of the axial abutment. female or male axial abutment is a flat surface forming a ring around the suction duct. It is conceivable to arrange the three moving flat surfaces at 120 ° to increase the stability of the assembly.
Selon un mode de réalisation, ladite surface plane formant une couronne est embarquée sur la pièce femelle.According to one embodiment, said flat surface forming a crown is embedded on the female part.
Selon un mode de réalisation, la pièce mâle et la pièce femelle forment chacune une portion du conduit d'aspiration.According to one embodiment, the male piece and the female piece each form a portion of the suction duct.
Selon un mode de réalisation, les moyens élastiques, l'une de la butée axiale femelle ou de la butée axiale mâle liée aux moyens élastiques et la bague rotative sont embarqués sur l'une de la pièce mâle ou de la pièce femelle.According to one embodiment, the elastic means, one of the female axial stop or the male axial stop connected to the elastic means and the rotary ring are embedded on one of the male part or the female part.
Selon un mode de réalisation, la bague rotative est agencée pour pouvoir être commandée manuellement par un utilisateur.According to one embodiment, the rotary ring is arranged to be manually controlled by a user.
Un second aspect de l'invention est un aspirateur comprenant au moins un conduit d'aspiration et au moins un dispositif selon le premier aspect de l'invention.A second aspect of the invention is a vacuum cleaner comprising at least one suction duct and at least one device according to the first aspect of the invention.
On peut envisager d'utiliser le dispositif d'accouplement entre les différents accessoires d'un aspirateur, tels que :
- le suceur et le tube, télescopique ou non ;
- le tube télescopique et la crosse ;
- la crosse et le flexible ;
- le flexible et l'aspirateur.
- the nozzle and the tube, telescopic or not;
- the telescopic tube and the stick;
- the butt and the hose;
- the hose and the vacuum cleaner.

La pièce mâle 20 est agencée pour s'insérer dans la pièce femelle 10 jusqu'à une position d'accouplement, et comme cela sera expliqué ci-dessous, le dispositif d'accouplement est agencé de telle sorte que l'insertion de la pièce mâle 20 dans la pièce femelle 10 conduisant automatiquement à un accouplement verrouillé ne requiert qu'un seul mouvement axial de la part de l'utilisateur, et le déverrouillage puis le retrait de la pièce mâle 20 hors de la pièce femelle 10 ne requièrent qu'un mouvement de rotation de la bague rotative 30 de la part de l'utilisateur.The

Comme expliqué à la
De plus, l'embout 20a comprend des dents 25 de forme sensiblement conique qui sont agencées pour s'engager dans des dents 15 également coniques de la pièce femelle 10, afin d'empêcher toute rotation de la pièce mâle 20 lorsqu'elle est verrouillée dans la pièce femelle 10. En d'autres termes, les dents 15 et 25 forment des moyens de butée angulaire, lorsque la pièce mâle 20 est accouplée dans la pièce femelle 10.In addition, the

En conclusion, l'insertion et le verrouillage automatique de la pièce mâle 20 dans la pièce femelle 10 ne nécessitent qu'un mouvement axial de la part de l'utilisateur.In conclusion, insertion and automatic locking of the

Dans le cas représenté sur la
Il est à noter que l'utilisateur n'agit que sur la bague rotative 30, et n'a pas besoin de maintenir l'embout 20a pour l'empêcher de tourner, car même si une partie du couple de rotation exercée sur la bague rotative 30 par l'utilisateur est transmise à l'embout 20a par l'intermédiaire des ergots d'actionnement, l'embout 20a est bloqué en rotation par les dents 25 de l'embout 20a engagées dans les dents 15 de la pièce femelle 10. Cet effet est obtenu par les dents 15 et 25 coniques lorsque la pièce mâle 20 est verrouillée dans la pièce femelle 10. L'utilisateur n'a qu'à appliquer une rotation à la bague rotative 30.It should be noted that the user only acts on the
Cependant, dès que la rotation de la bague rotative 30 pousse les surfaces planes 21 suffisamment pour qu'elles ne soient plus en regard de la surface plane 11, alors un mouvement de retrait axial de la pièce mâle 20 est possible, et ce mouvement de retrait est même provoqué par le dispositif lui-même. En effet, les dents 25 de la pièce mâle 20 et les dents 15 de la pièce femelle 10 sont coniques ou en pente, et agissent comme une came qui transforme le couple et/ou le mouvement rotatif de la pièce mâle 20 en effort et/ou mouvement axial de retrait de la pièce mâle 20, si bien que le mouvement de retrait est automatique.However, as soon as the rotation of the
De plus, ce mouvement de retrait, prédéterminé par la hauteur des dents 25 de la pièce mâle 20 et celles de la pièce femelle 10, est calculé pour éjecter la pièce mâle 20 de sorte que les ergots de clipsage 23 soient en regard de la piste de guidage conique 12 de la pièce femelle 10. Ainsi, les pattes élastiques 24 qui exercent un effort radial sur la piste de guidage conique 12 créent à leur tour un effort axial sur la pièce mâle 20, de sorte qu'elle est poussée encore un peu plus hors de la pièce femelle 10.In addition, this withdrawal movement, predetermined by the height of the
En d'autres termes, le déverrouillage de la pièce mâle 20, provoqué par la rotation de la bague rotative 30, crée un mouvement axial de retrait de la pièce mâle 20, qui est à nouveau éjectée hors de la pièce femelle 10 par l'action des pattes élastiques 24.In other words, the unlocking of the
En conclusion, l'accouplement du dispositif peut être réalisé avec un seul mouvement axial de l'utilisateur imposé à la pièce mâle 20 conduisant à un verrouillage automatique, et un seul mouvement rotatif de déverrouillage appliqué par l'utilisateur sur la bague rotative 30 conduisant au déverrouillage et à l'éjection automatique de la pièce mâle, ce qui procure une bonne ergonomie d'utilisation au dispositif.In conclusion, the coupling of the device can be achieved with a single axial movement of the user imposed on the
