Description
La présente invention concerne des perfectionnements apportés aux boîtiers à raccord tournant pour suceur d'aspirateur.The present invention relates to improvements made to housings with a rotary coupling for a vacuum cleaner nozzle.
Un boîtier à raccord tournant pour suceur d'aspirateur comporte généralement un dessus et une paroi latérale dont la partie postérieure fait corps avec un manchon. Ce manchon débouchant à l'extérieur est destiné à recevoir une tubulure d'un raccord branché rigidement ou de façon articulée sur un manche tubulaire d'aspirateur. La tubulure du raccord est montée tournante autour d'un axe antéro-postérieur et immobilisée en translation dans le manchon.A rotary connector housing for a vacuum cleaner nozzle generally has a top and a side wall, the rear part of which forms a body. This sleeve opening to the outside is intended to receive a tubing of a connector rigidly connected or articulated on a tubular handle of a vacuum cleaner. The connection tubing is mounted to rotate about an anteroposterior axis and immobilized in translation in the sleeve.
Le dessus du boîtier fait corps avec un conduit interne sensiblement vertical, faisant communiquer la tubulure de raccordement précitée avec une fenêtre d'une semelle de glissement rapportée et fixée sous le boîtier, fenêtre qui débouche dans un canal longitudinal aspirant de la semelle.The top of the housing forms a body with a substantially vertical internal conduit, communicating the aforementioned connection tubing with a window of a slip sole fitted and fixed under the housing, window which opens into a longitudinal channel suction from the sole.
Un premier type connu de montage tournant de la tubulure consiste à ménager de moulage dans la tubulure près de son extrémité libre une gorge débouchant à l'extérieur et dans le manchon près du conduit une gorge débouchant à l'intérieur, à disposer ces deux gorges en regard l'une de l'autre lorsqu'un épaulement de la tubulure bute contre l'extrémité libre du manchon et à loger dans ces gorges un anneau fendu déformable élastiquement. Cet anneau dénommé habituellement circlip assure la liaison indémontable de la tubulure avec le manchon, liaison qui permet de tourner mais non de se déboîter.A first known type of rotary mounting of the tubing consists in providing a molding opening in the tubing near its free end, a groove opening on the outside and in the sleeve near the duct, a groove opening on the inside, placing these two grooves facing each other when a shoulder of the tubing abuts against the free end of the sleeve and to accommodate in these grooves an elastically deformable split ring. This ring usually called a circlip ensures the non-removable connection of the tubing with the sleeve, a connection which allows it to rotate but not to disengage.
L'inconvénient de ce premier type de montage est que l'épaisseur du manchon n'est pas constante et qu'il en résulte des difficultés de moulage, des retassures nuisant à l'esthétique de la pièce finie et un abaissement de la cadence d'injection. Par ailleurs, la tubulure est indémontable, ce qui peut être préjudiciable à un bon entretien du suceur.The drawback of this first type of mounting is that the thickness of the sleeve is not constant and that this results in molding difficulties, shrinkage detrimental to the aesthetics of the finished part and a lowering of the rate d 'injection. Furthermore, the tubing is non-removable, which can be detrimental to good maintenance of the nozzle.
Un deuxième type connu de montage tournant de la tubulure consiste à engager deux tiges parallèles dans le manchon afin qu'elles pénètrent tangentiellement dans la gorge de la tubulure.A second known type of rotary mounting of the tubing consists in engaging two parallel rods in the sleeve so that they penetrate tangentially into the groove of the tubing.
Par ailleurs, le moulage laisse apparaître des marques dues aux retassures, marques qui compromettent l'esthétique.Furthermore, the molding reveals marks due to shrinkage, marks that compromise aesthetics.
Le moulage se trouve dans ce cas amélioré. Le démontage bien que difficile devient possible mais s'accompagne souvent de détériorations. Par contre, le guidage est défectueux et donne naissance très rapidement à un jeu nuisant à la manoeuvre du suceur.The molding is in this case improved. Disassembly although difficult becomes possible but is often accompanied by deterioration. By cons, the guide is defective and gives rise very quickly to a game detrimental to the operation of the squeegee.
Indépendamment du montage tournant de la tubulure se posent, le problème de l'amélioration de l'écoulement du flux gazeux et le problème de l'étanchéité du montage à l'air et à l'eau. En effet, lorsque le suceur est utilisé sur des sols mouillés, il "bave" au niveau du joint tournant de la tubulure connue, ce qui, d'une part, est salissant, d'autre part, compromet l'efficacité de l'aspiration, enfin, nuit à l'image de qualité auprès de la clientèle, sachant que cette amélioration ne doit pas s'accompagner d'une difficulté de moulage.Regardless of the rotating assembly of the tubing arise, the problem of improving the flow of the gas flow and the problem of sealing the assembly with air and water. Indeed, when the nozzle is used on wet floors, it "drools" at the rotating joint of the known tubing, which, on the one hand, is dirty, on the other hand, compromises the effectiveness of the aspiration, finally, harms the image of quality with customers, knowing that this improvement should not be accompanied by a difficulty in molding.
La présente invention a pour but de remédier à ces inconvénients:
- en proposant un moyen de montage tournant tel que l'épaisseur du manchon est constante, que le guidage de la tubulure est pratiquement parfait et que le démontage de ladite tubulure est faisable facilement et sans détérioration,
- et en apportant concomitamment les moyens nécessaires à assurer un meilleur écoulement du flux gazeux et à réduire les risques de dépôt des particules (poussières, fibres, cheveux...) dans le suceur et de fuite à l'extérieur, en même temps que ces moyens permettent de faciliter le moulage, d'accroître la cadence d'injection et donc de diminuer le prix de revient, d'éliminer les défauts apparents : retassures, point d'injection...The object of the present invention is to remedy these drawbacks:
by proposing a rotary mounting means such that the thickness of the sleeve is constant, that the guidance of the tubing is practically perfect and that the disassembly of said tubing is easily and without deterioration possible,
- and by concomitantly providing the means necessary to ensure a better flow of the gas flow and to reduce the risks of deposition of particles (dust, fibers, hair, etc.) in the nozzle and of leakage outside, at the same time as these means facilitate molding, increase the injection rate and therefore reduce the cost price, eliminate apparent defects: shrinkage, injection point ...
Dans ce but et conformément à l'invention :
- le manchon est exempt de gorge, présente une épaisseur sensiblement constante et délimite une encoche s'étendant sensiblement sur la moitié supérieure de sa périphérie en regard d'une ouverture ménagée dans le dessus du boîtier,
- la tubulure comporte une portée cylindrique montée tournante dans le manchon et limitée par un épaulement butant contre l'extrémité libre de celui-ci, position dans laquelle une gorge de cette tubulure est située en regard de l'encoche précitée du manchon,
- une patte délimite un évidement semi-circulaire de diamètre au moins égal au plus près au diamètre à fond de gorge de la tubulure, est susceptible de traverser l'encoche du manchon pour pénétrer dans la gorge et fait corps avec un couvercle clipsable normalement emboîté dans l'ouverture précitée du boîtier, position dans laquelle la tubulure est immobilisée en translation à l'extérieur par butée de son épaulement contre l'extrémité libre du manchon et à l'intérieur par butée du chant antérieur de sa gorge contre le bord semi-circulaire supérieur de l'évidement de la patte rapportée.For this purpose and in accordance with the invention:
the sleeve is free from a groove, has a substantially constant thickness and delimits a notch extending substantially over the upper half of its periphery opposite an opening made in the top of the housing,
- the tubing has a cylindrical seat rotatably mounted in the sleeve and limited by a butting shoulder against the free end of the latter, position in which a groove of this tube is located opposite the aforementioned notch of the sleeve,
- a tab delimits a semicircular recess with a diameter at least equal as close as possible to the diameter at the bottom of the throat of the tubing, is capable of passing through the notch of the sleeve to penetrate the throat and is integral with a clip-on cover normally fitted in the aforementioned opening of the housing, position in which the tubing is immobilized in translation on the outside by abutment of its shoulder against the free end of the sleeve and on the inside by abutment of the front edge of its groove against the semi edge -circular upper of the recess of the attached leg.
Suivant une forme de réalisation particulièrement avantageuse, le bord postérieur de l'encoche du manchon est en pente divergente vers le haut pour coopérer avec des rampes inclinées latérales de la patte destinées à positionner axialement la tubulure dans ledit manchon ; le chant antérieur de la gorge de la tubulure est situé en regard du bord antérieur de l'encoche du manchon.According to a particularly advantageous embodiment, the rear edge of the notch of the sleeve is in a divergent upward slope to cooperate with inclined lateral ramps of the tab intended to position the tubing axially in said sleeve; the front edge of the throat of the tubing is located opposite the front edge of the notch of the sleeve.
Pour mieux résister à l'usure, un feuillard métallique ayant sensiblement la forme de la patte peut être interposé entre elle-ci et le chant antérieur de la gorge de la tubulure.To better resist wear, a metal strip having substantially the shape of the tab can be interposed between it and the front edge of the groove of the tube.
En ce qui concerne plus spécialement le boîtier, celui-ci comportant un conduit interne vertical qui débouche en haut dans le manchon et en bas dans une fenêtre d'une semelle normalement fixée sous ce boîtier, selon l'invention, le conduit est coudé en haut vers le manchon pour diminuer les pertes de charge, l'ouverture du dessus du boîtier normalement obturée par le couvercle de la patte précitée ayant une largeur déterminée en correspondance avec l'étendue antéro-postérieure du coude pour permettre le passage de la partie du moule qui définit la forme extérieure supérieure du coude, ainsi que de la buse d'injection.As regards more specifically the housing, the latter comprising a vertical internal conduit which opens at the top into the sleeve and at the bottom in a window of a sole normally fixed under this housing, according to the invention, the conduit is bent in top towards the sleeve to reduce pressure losses, the opening of the top of the housing normally closed by the cover of the aforementioned tab having a width determined in correspondence with the anteroposterior extent of the elbow to allow the passage of the part of the mold which defines the upper external shape of the elbow, as well as of the injection nozzle.
Divers autres caractéristiques et avantages de l'invention ressortent d'ailleurs de la description détaillée qui suit.Various other characteristics and advantages of the invention will also emerge from the detailed description which follows.
Une forme de réalisation de l'objet de l'invention et une variante sont représentées, à titre d'exemples non limitatifs, sur le dessin annexé.An embodiment of the object of the invention and a variant are shown, by way of nonlimiting examples, in the accompanying drawing.

Une tubulure d'aspiration 11 est susceptible d'être raccordée par son extrémité coudée 12 à un manche d'aspirateur. Son extrémité libre 13 forme un embout tubulaire qui fait saillie sur un épaulement 14. L'embout 13 comporte des portées cylindriques 15 à 17 destinées à être emboîtées dans le manchon 5. Entre les portées 15 et 16 sont prévues des lèvres annulaires d'étanchéité 18 et une gorge d'immobilisation axiale 19 sépare les portées 16 et 17.A suction pipe 11 can be connected by its
Le conduit 6 présente à sa base une section rectangulaire raccordée au manchon 5 par une paroi postérieure verticale 20, par une paroi antérieure verticale 21 prolongée par un coude supérieur 22 (figure 1) et par des parois latérales verticales 23 prolongées par des parois convergentes 24 raccordées au coude 22 (figure 2).The
Le conduit 6 ainsi conformé relie la fenêtre 7 au manchon 5 avec une variation progressive de la section et une déviation guidée en courbe de la direction de l'écoulement. Ce conduit 6 fait corps avec le dessus 2 du boîtier par l'intermédiaire d'une cuvette parallélépipédique 25. Le fond 26 de la cuvette est solidaire du conduit 6, tandis que la paroi périphérique 27 de cette cuvette qui est écartée de ce conduit 6 est solidaire du dessus 2 du boîtier ainsi que de la moitié supérieure du manchon 5.The
La paroi périphérique 27 délimite dans le dessus 2 une ouverture 28 à travers laquelle peut passer une partie du moule, définissant la forme de la portion extérieure haute du manchon 5 et du conduit 6 ainsi que la forme intérieure de la cuvette 25. Il est prévu de fermer l'ouverture 28 au moyen d'un couvercle 29 se positionnant dans un embrèvement du dessus 2 et se fixant, de façon démontable, au moyen de languettes flexibles à dents 30 clipsées dans des lumières 31 de la cuvette 25.The
Le couvercle 29 fait corps avec une patte 32 délimitant un évidement semi-circulaire 33 dont le diamètre est sensiblement égal au diamètre du fond de la gorge 19 de l'embout 13 de la tubulure 11. Par ailleurs, une encoche 34 est ménagée dans le manchon 5 et délimitée par un bord postérieur pentu 36 qui diverge vers le haut.The
Lorsque l'embout 13 de la tubulure tournante 11 est emboîté dans le manchon 5 du boîtier et que son épaulement 14 bute contre l'extrémité extérieure libre de ce manchon 5, la patte 32 du couvercle 29 posé, pénètre dans la gorge 19 de l'embout 13 et immobilise, par butée contre le chant postérieur 37 de ladite gorge, en translation ledit embout sans s'opposer à sa rotation. Pour bien verrouiller cette immobilisation, la patte 32 fait corps avec des rampes inclinées 38 coopérant avec les bords postérieurs pentus 36 des encoches 34 du manchon 5. Avantageusement, les bords antérieurs 35 des encoches peuvent être alignés avec le chant antérieur 37 de la gorge 19 de l'embout 13 lorsque celui-ci est en place pour que la patte 32 et ses rampes 38 se coincent parfaitement dans lesdites encoches.When the
Bien entendu, pour assurer le montage tournant de la tubulure, il n'est nullement nécessaire de prévoir la cuvette 25 et un couvercle 29 aussi grand. En effet, la patte amovible 32 suffit. Mais dans ce cas, le haut du conduit 6 ne peut pas être coudé et s'étend jusqu'au-dessus 2 du boîtier.Of course, to ensure the rotary mounting of the tubing, there is no need to provide the
