Un tire-bouchon de type « à double levier » permet classiquement de faciliter le retrait d'un bouchon du goulot d'une bouteille en répartissant sur les deux bras d'un utilisateur l'effort de traction à fournir.A corkscrew of the “double lever” type conventionally makes it possible to facilitate the removal of a cork from the neck of a bottle by distributing the pulling force to be supplied over the two arms of a user.

A l'heure actuelle, les tire-bouchons à double bras de levier disponibles sur le marché présentent des caractéristiques structurelles communes et peuvent être regroupés dans deux catégories différentes selon la nature de ces dernières.At present, the double lever arm corkscrews available on the market have common structural characteristics and can be grouped into two different categories depending on the nature of the latter.

Ainsi, dans une première catégorie, les tire-bouchons à double bras de levier comportent principalement un corps tubulaire réalisé en un matériau rigide, généralement en ZAMAK (marque déposée) ou en un autre matériau plastique dur sur lequel viennent tourner en phase deux bras de levier. Ces bras sont prolongés par une roue partiellement dentée s'engrenant dans une crémaillère solidaire de la vrille et qui se déplace en translation suivant l'axe de la vrille entre une position haute et une position basse. La mise en oeuvre d'un tire-bouchon à double bras de levier conforme à cette première catégorie suppose les étapes suivantes :

  1. 1. Positionnement du tire-bouchon sur le goulot d'une bouteille, les deux bras de levier étant abaissés et rabattus contre le corps du tire-bouchon et la crémaillère étant placée en position haute,
  2. 2. Saisie, à l'aide d'une même main, du tire-bouchon au niveau de la portion comprenant les deux bras de levier et de la bouteille,
  3. 3. Saisie avec l'autre main de la poignée prolongeant la crémaillère,
  4. 4. Vissage de la vrille dans le bouchon en prenant garde de maintenir fermement le tire-bouchon ainsi que la bouteille afin de prévenir toute rotation intempestive de cette dernière par rapport au tire-bouchon, et ce jusqu'à ce que les deux bras de levier commencent à s'écarter du corps tubulaire pour atteindre une position levée,
  5. 5. Lâchage du tire-bouchon lorsque les deux bras de levier se lèvent,
  6. 6. Lorsque les deux bras sont assez levés maintien, à nouveau avec une main, de la portion inférieure du corps tubulaire et de la bouteille et insertion de la vrille jusqu'à la course maximale des deux bras de levier,
  7. 7. Action des deux mains sur les bras de levier pour les replacer en position basse rabattus contre le corps tubulaire et extraire le bouchon,
  8. 8. Traction sur le tire-bouchon au moyen de la poignée dont est pourvue la crémaillère, afin de procéder à l'extraction complète du bouchon, car la course des bras est généralement trop faible,
  9. 9. Préhension du bouchon,
  10. 10. Maintien en même temps de la tête de la crémaillère et dévissage de la vrille pour libérer le bouchon.
Thus, in a first category, double lever arm corkscrews mainly comprise a tubular body made of a rigid material, generally ZAMAK (registered trademark) or another hard plastic material on which two lever arms rotate in phase. lever. These arms are extended by a partially toothed wheel meshing in a rack integral with the auger and which moves in translation along the axis of the auger between a high position and a low position. The implementation of a corkscrew with double lever arm conforming to this first category supposes the following steps:
  1. 1. Positioning of the corkscrew on the neck of a bottle, the two lever arms being lowered and folded against the body of the corkscrew and the rack being placed in the raised position,
  2. 2. Grasp, using the same hand, the corkscrew at the level of the portion comprising the two lever arms and the bottle,
  3. 3. Grip with the other hand of the handle extending the rack,
  4. 4. Screwing the auger into the cork, taking care to firmly hold the corkscrew as well as the bottle in order to prevent any untimely rotation of the latter in relation to the corkscrew, until the two arms of the lever begin to move away from the tubular body to reach a raised position,
  5. 5. Release of the corkscrew when the two lever arms rise,
  6. 6. When the two arms are sufficiently raised holding, again with one hand, the lower portion of the tubular body and the bottle and inserting the twist until the maximum travel of the two lever arms,
  7. 7. Action of the two hands on the lever arms to replace them in the lower position folded against the tubular body and extract the cap,
  8. 8. Traction on the corkscrew by means of the handle with which the rack is provided, in order to proceed with the complete extraction of the cork, because the stroke of the arms is generally too short,
  9. 9. Cap gripping,
  10. 10. Simultaneously holding the rack head and unscrewing the gimlet to release the plug.

Ce type de tire-bouchon, dont on connaît des exemples de réalisation des publications WO 03/031312 et DE 20 2009 004 857 , présente l'inconvénient de nécessiter, lors de son usage, de nombreux gestes supposant une certaine dextérité. Il se révèle de manipulation particulièrement fastidieuse lors de la plupart des étapes énumérées ci-dessus. En particulier, des difficultés de manipulation ont été constatées pendant le vissage de la vrille dans le bouchon car, à ce stade, il est nécessaire de maintenir fermement à la fois la partie basse du tire-bouchon et la bouteille afin d'éviter qu'elle ne tourne, ce qui suppose une certaine force physique. Par ailleurs, la phase au cours de laquelle les bras de levier commencent à se lever présente également un caractère délicat et suppose une attention particulière étant donné que l'utilisateur doit, au moins pendant quelques secondes, desserrer sa main pour permettre le mouvement des bras de levier. Enfin, le retrait complet du bouchon suppose souvent une intervention complémentaire de la part de l'utilisateur et des blessures dues à un contact inopportun avec la pointe de la vrille lors du dévissage du bouchon ont également été rapportées.This type of corkscrew, examples of which are known from the publications WO 03/031312 And FROM 20 2009 004 857 , has the disadvantage of requiring, during its use, many gestures assuming a certain dexterity. It turns out to be particularly tedious handling during most of the steps listed above. In particular, handling difficulties have been observed during the screwing of the auger into the cork because, at this stage, it is necessary to firmly hold both the lower part of the corkscrew and the bottle in order to prevent it doesn't turn, which requires some physical strength. Furthermore, the phase in which the lever arms begin to rise also has a delicate character and requires special attention since the user must, at least for a few seconds, loosen his hand to allow the movement of the arms. of leverage. Finally, the complete removal of the cork often requires additional intervention on the part of the user and injuries due to inappropriate contact with the tip of the auger when unscrewing the cork have also been reported.

La publication WO 03/031312 A2 divulgue un tire-bouchon comprenant les caractéristiques techniques du préambule de la revendication 1.The publication WO 03/031312 A2 discloses a corkscrew comprising the technical features of the preamble of claim 1.

Les tire-bouchons à double bras de levier de la deuxième famille comportent, comme ceux de la première famille, un corps tubulaire rigide, deux bras de levier et une crémaillère en translation par rapport à l'axe de la vrille. Dans cette deuxième famille, les tire-bouchons sont en outre équipés d'un système permettant de désolidariser les bras de levier par rapport à la crémaillère munie de la vrille grâce à un système de cliquet. Une telle structure permet ainsi d'éviter que les deux bras de levier ne se lèvent pendant l'insertion de la vrille dans le bouchon, et supprime le caractère délicat de la manipulation de tels tire-bouchons pendant cette phase. Néanmoins, l'ensemble des autres inconvénients cités ci-dessus pour la première famille se pose toujours avec les tire-bouchons de la seconde famille qui ne donnent par conséquent pas davantage satisfaction.The double lever arm corkscrews of the second family comprise, like those of the first family, a rigid tubular body, two lever arms and a rack in translation with respect to the axis of the gimlet. In this second family, the corkscrews are also equipped with a system allowing the lever arms to be separated from the rack fitted with the spin using a ratchet system. Such a structure thus makes it possible to prevent the two lever arms from rising during the insertion of the auger into the cork, and eliminates the delicate nature of handling such corkscrews during this phase. Nevertheless, all of the other disadvantages mentioned above for the first family always arise with the corkscrews of the second family which consequently do not give any further satisfaction.

La présente invention a pour but de proposer un tire-bouchon à double bras de levier présentant une structure innovante permettant de pallier l'ensemble des inconvénients mentionnés ci-dessus et ainsi de fournir une solution présentant une ergonomie améliorée, permettant à un utilisateur d'extraire facilement, avec une aisance de manipulation et sans avoir à fournir une force démesurée, un bouchon retenu dans le goulot d'une bouteille. Par ailleurs, un autre objectif de l'invention est de fournir un tire-bouchon permettant une extraction complète d'un bouchon du goulot d'une bouteille lors de sa manipulation, tout en évitant les éventuels problèmes d'effritement parfois observés et dus à un vissage trop important de la vrille dans le bouchon.The object of the present invention is to provide a corkscrew with a double lever arm having an innovative structure making it possible to overcome all the drawbacks mentioned above and thus to provide a solution having improved ergonomics, allowing a user to extract easily, with ease of handling and without having to provide excessive force, a cork retained in the neck of a bottle. Furthermore, another object of the invention is to provide a corkscrew allowing complete extraction of a cork from the neck of a bottle during its handling, while avoiding the possible problems of crumbling sometimes observed and due to excessive screwing of the gimlet into the cork.

A cet effet, la présente invention concerne un tire-bouchon selon la revendication 1.To this end, the present invention relates to a corkscrew according to claim 1.

En d'autres termes, le tire-bouchon selon l'invention est équipé de moyens conçus aptes à empêcher les moyens de solidarisation à atteindre leur position active lorsque les bras de levier sont rabattus contre le corps dudit tire-bouchon. Ceci est particulièrement avantageux au cours de la phase de vissage de la vrille dans le bouchon, étant donné que les bras de levier demeurent alors immobiles, contrairement aux bras de levier des tire-bouchons classiques qui se déplacent pendant cette phase pour atteindre leur position écartée du corps du tire-bouchon. Ainsi, grâce à une telle caractéristique de l'invention, l'utilisateur n'est jamais gêné par les bras de levier au cours de sa manipulation, laquelle est rendue moins fastidieuse par voie de conséquence.In other words, the corkscrew according to the invention is equipped with means designed capable of preventing the securing means from reaching their active position when the lever arms are folded against the body of said corkscrew. This is particularly advantageous during the phase of screwing the gimlet into the cork, given that the lever arms then remain motionless, unlike the lever arms of conventional corkscrews which move during this phase to reach their position away from the body of the corkscrew. Thus, thanks to such a feature of the invention, the user is never bothered by the lever arms during its manipulation, which is made less tedious as a result.

Conformément à l'invention, chaque roue dentée comporte au moins un épaulement s'étendant entre la base de ses dents et une de ses faces et en ce que lesdits moyens de solidarisation d'un bras de levier avec une roue dentée comportent un organe, présentant au moins une branche rectiligne, monté mobile en translation le long de l'axe longitudinal dudit bras de levier dans un fourreau dont est pourvu ledit bras de levier, entre une position rentrée dans ledit fourreau, correspondant à son état inactif, et une position partiellement extraite du fourreau, correspondant à son état actif, dans laquelle une portion supérieure de la branche rectiligne est engagée dans une encoche, formée radialement dans l'épaulement de ladite roue dentée, le déplacement dudit organe de son état actif vers son état inactif s'effectuant à l'encontre d'un moyen de rappel élastique inséré entre un fond que comporte le fourreau et un bord inférieur dudit organe.According to the invention, each toothed wheel comprises at least one shoulder extending between the base of its teeth and one of its faces and in that said means for securing a lever arm with a toothed wheel comprise a member, having at least one rectilinear branch, mounted movable in translation along the longitudinal axis of said lever arm in a sleeve with which said lever arm is provided, between a retracted position in said sleeve, corresponding to its inactive state, and a position partially extracted from the sheath, corresponding to its active state, in which an upper portion of the rectilinear branch is engaged in a notch, formed radially in the shoulder of the said toothed wheel, the displacement of the said member from its active state to its inactive state s 'performing against an elastic return means inserted between a bottom that includes the sheath and a lower edge of said member.

Dans ce cas, l'invention prévoit par ailleurs que chaque épaule d'articulation comporte au moins une patte s'étendant depuis la tête de guidage entre une paroi du bras de levier et la face de la roue dentée formant ledit épaulement avec la base des dents, tandis que la largeur de la branche rectiligne formant ledit organe présente une dimension correspondant sensiblement à l'épaisseur de la patte plus la largeur de l'encoche, et que le fourreau est formé sur ledit bras de levier de manière telle que la portion supérieure dudit organe s'étende, lors de la rotation du bras de levier, vis-à-vis à la fois du chant de la patte et de l'encoche, et en ce que le chant de ladite patte forme une courbe comportant un tronçon inférieur dont les points sont situés à une distance de l'axe supérieure au rayon des faces de la roue dentée et un tronçon latéral et supérieur dont les points sont situés à une distance de l'axe inférieure au rayon des faces de la roue dentée.In this case, the invention also provides that each hinge shoulder comprises at least one lug extending from the guide head between a wall of the lever arm and the face of the toothed wheel forming said shoulder with the base of the teeth, while the width of the rectilinear branch forming said member has a dimension corresponding substantially to the thickness of the lug plus the width of the notch, and the sleeve is formed on said lever arm in such a way that the portion upper part of said member extends, during the rotation of the lever arm, vis-à-vis both the edge of the lug and of the notch, and in that the edge of the said lug forms a curve comprising a lower section whose points are located at a distance from the axis greater than the radius of the faces of the toothed wheel and a lateral section and upper whose points are located at a distance from the axis less than the radius of the faces of the toothed wheel.

Selon une variante de réalisation préférentielle de l'invention, le présent tire-bouchon se caractérise en ce que ledit organe présente une structure sensiblement en « U » et comporte deux branches rectilignes reliées par une branche transversale, tandis que chaque roue dentée comporte deux épaulements s'étendant respectivement entre chacune de ses faces et la base de ses dents, et deux encoches formées l'une en face de l'autre sur chaque épaulement et conçues aptes à recevoir simultanément la portion supérieure d'une des branches rectilignes dudit organe en « U » dans l'état actif de celui-ci, et en ce que chaque épaule d'articulation est constituée par une paire de pattes s'étendant chacune depuis la tête de guidage entre une face de la roue dentée et une paroi avant ou arrière du bras de levier.According to a preferred embodiment of the invention, this corkscrew is characterized in that said member has a substantially "U" structure and comprises two rectilinear branches connected by a transverse branch, while each toothed wheel has two shoulders extending respectively between each of its faces and the base of its teeth, and two notches formed one opposite the other on each shoulder and designed capable of simultaneously receiving the upper portion of one of the rectilinear branches of said member in "U" in the active state thereof, and in that each hinge shoulder is constituted by a pair of legs each extending from the guide head between a face of the toothed wheel and a front wall or back of the lever arm.

Dans ce cas, il est prévu que lesdites encoches sont formées vis-à-vis de l'espace compris entre deux dents consécutives et en ce que la distance comprise entre la face supérieure de la branche transversale de l'organe en « U » et le bord supérieur des branches rectilignes est supérieure à la hauteur d'une encoche et inférieure à la distance comprise entre le fond d'une encoche et le sommet d'une dent.In this case, it is provided that said notches are formed vis-à-vis the space between two consecutive teeth and in that the distance between the upper face of the transverse branch of the "U" member and the upper edge of the straight branches is greater than the height of a notch and less than the distance between the bottom of a notch and the top of a tooth.

Par ailleurs, conformément à une caractéristique additionnelle de l'invention, la face inférieure de la branche transversale de l'organe en « U » et le fond du fourreau comportent des renfoncements coaxiaux aptes à loger respectivement l'extrémité supérieure et l'extrémité inférieure du moyen de rappel élastique.Furthermore, in accordance with an additional characteristic of the invention, the lower face of the transverse branch of the "U"-shaped member and the bottom of the sheath comprise coaxial recesses capable of housing respectively the upper end and the lower end of the elastic return means.

L'invention prévoit en outre que le fourreau s'étend le long d'une face transversale du bras de levier entre ses faces avant et arrière.The invention further provides that the sheath extends along a transverse face of the lever arm between its front and rear faces.

Egalement, il a été imaginé que le corps tubulaire présente une forme tronconique dans laquelle le diamètre de sa portion inférieure est supérieur au diamètre de sa portion médiane, et que la paroi périphérique du corps tubulaire comporte deux lumières longitudinales s'étendant l'une en face de l'autre, entre les deux épaules d'articulation, depuis la tête de guidage jusqu'au bord inférieur du corps tubulaire, et délimitant sur le corps tubulaire deux ailes longitudinales contre chacune desquelles repose un bras de levier dans sa position rabattue contre le corps tubulaire.Also, it has been imagined that the tubular body has a frustoconical shape in which the diameter of its lower portion is greater than the diameter of its middle portion, and that the peripheral wall of the tubular body comprises two longitudinal slots extending one in face of the other, between the two hinge shoulders, from the guide head to the lower edge of the tubular body, and delimiting on the tubular body two longitudinal wings against each of which rests a lever arm in its folded-down position against the tubular body.

De préférence, il est prévu qu'au moins les deux ailes longitudinales du corps tubulaire sont réalisées en un matériau déformable.Preferably, provision is made for at least the two longitudinal wings of the tubular body to be made of a deformable material.

Avantageusement, le tire-bouchon selon l'invention peut en outre comporter des moyens de blocage en rotation du corps tubulaire par rapport à un goulot d'une bouteille.Advantageously, the corkscrew according to the invention may also comprise means for locking the tubular body in rotation with respect to a neck of a bottle.

De plus, le corps tubulaire peut comporter au niveau de sa portion inférieure, sur la face interne de chacune des ailes longitudinales, une bande d'un matériau élastomère logée dans un renfoncement s'étendant entre le bord inférieur du corps tubulaire et un épaulement formé entre la portion inférieure et la portion médiane du corps tubulaire.In addition, the tubular body may comprise at its lower portion, on the internal face of each of the longitudinal flanges, a strip of an elastomeric material housed in a recess extending between the lower edge of the tubular body and a shoulder formed between the lower portion and the middle portion of the tubular body.

Par ailleurs, le corps tubulaire présente préférentiellement une longueur telle que ladite vrille demeure intégralement logée à l'intérieur de sa portion inférieure dans la position basse de ladite crémaillère tandis que le bord inférieur du corps tubulaire présente une face d'appui sur un plan s'étendant entre la face interne et la face externe de sa paroi périphérique.Furthermore, the tubular body preferably has a length such that said twist remains fully housed inside its lower portion in the low position of said rack while the lower edge of the tubular body has a bearing face on a plane s extending between the inner face and the outer face of its peripheral wall.

Le tire-bouchon selon l'invention est en option encore caractérisé en ce qu'il peut comporter des moyens de signalisation de la profondeur de vissage de ladite vrille dans le bouchon d'une bouteille, lesquels peuvent être définis par au moins un repère apposé sur ladite crémaillère, représentatif d'une profondeur de vissage de la vrille dans un bouchon à ne pas dépasser.The corkscrew according to the invention is optionally further characterized in that it may include means for signaling the screwing depth of said twist in the cork of a bottle, which may be defined by at least one mark affixed on said rack, representative of a screwing depth of the auger in a plug not to be exceeded.

D'autres caractéristiques et avantages de l'invention ressortiront de la description détaillée qui va suivre, se rapportant à un exemple de réalisation du tire-bouchon selon l'invention donné uniquement à titre indicatif et non limitatif.Other characteristics and advantages of the invention will become apparent from the detailed description which follows, relating to an embodiment of the corkscrew according to the invention given solely by way of indication and not limitation.

De manière classique, le tire-bouchon 1 selon l'invention comporte un corps tubulaire 2 hébergeant une vrille 3 solidaire d'une crémaillère 4 prolongée par une poignée 5 permettant son actionnement. Le corps tubulaire 2 présente une portion inférieure 20 conçue apte à épouser un goulot 6 d'une bouteille 7 et une portion supérieure 21 définissant une tête de guidage en translation et en rotation de la crémaillère 4 le long et autour de l'axe du corps tubulaire 2 entre une position basse (cf. fig. 3 et 4) et une position haute (cf. fig. 1 et 2) dans lesquelles l'extrémité libre 30 de la vrille 3 s'étend respectivement dans la portion inférieure 20 et dans une portion médiane 22 du corps tubulaire 2.Conventionally, the corkscrew 1 according to the invention comprises a tubular body 2 housing a swirler 3 secured to a rack 4 extended by a handle 5 allowing its actuation. The tubular body 2 has a lower portion 20 designed able to marry a neck 6 of a bottle 7 and an upper portion 21 defining a guide head in translation and in rotation of the rack 4 along and around the axis of the body tubular 2 between a low position (cf. fig. 3 and 4 ) and a high position (cf. fig. 1 and 2 ) in which the free end 30 of the auger 3 extends respectively in the lower portion 20 and in a middle portion 22 of the tubular body 2.

Le tire-bouchon 1 selon l'invention comporte en outre deux sous-ensembles, comportant chacun un bras de levier 8 et une roue dentée 9 s'engrenant dans la crémaillère 4 au travers d'une fenêtre 37 formée dans la portion supérieure 21 du corps tubulaire 2. Chacun de ces sous-ensembles est monté en rotation autour d'un axe 10 perpendiculaire à l'axe du corps tubulaire 2, sur une épaule d'articulation 11 bordant la tête de guidage 21. Ainsi, les bras de levier 8 peuvent être déplacés entre une position rabattue contre le corps tubulaire 2 (cf. fig. 1 et 2) et une position écartée du corps tubulaire 2 (cf. fig. 3 et 4), dans laquelle ils s'étendent de part et d'autre de la poignée 5.The corkscrew 1 according to the invention further comprises two subassemblies, each comprising a lever arm 8 and a toothed wheel 9 meshing in the rack 4 through a window 37 formed in the upper portion 21 of the tubular body 2. Each of these sub-assemblies is rotatably mounted about an axis 10 perpendicular to the axis of the tubular body 2, on an articulation shoulder 11 bordering the guide head 21. Thus, the lever arms 8 can be moved between a folded position against the tubular body 2 (cf. fig. 1 and 2 ) and a position separated from the tubular body 2 (cf. fig. 3 and 4 ), in which they extend on either side of the handle 5.

Par ailleurs, le tire-bouchon 1 comporte, pour chaque sous-ensemble, des moyens de solidarisation du bras de levier 8 avec la roue dentée 9, ces moyens de solidarisation étant agencés pour adopter un état actif dans lequel le bras de levier 8 est solidarisé de la roue dentée 9 et un état inactif dans lequel le bras de levier 8 est désolidarisé de la roue dentée 9, celle-ci pouvant alors tourner sans entraîner le bras de levier 8 lors de sa rotation.Furthermore, the corkscrew 1 comprises, for each subassembly, means for securing the lever arm 8 to the toothed wheel 9, these securing means being arranged to adopt an active state in which the lever arm 8 is secured to the toothed wheel 9 and an inactive state in which the lever arm 8 is disengaged from the toothed wheel 9, the latter then being able to rotate without driving the lever arm 8 during its rotation.

Conformément à l'invention, le tire-bouchon 1 comporte avantageusement des moyens de maintien des moyens de solidarisation dans leur état inactif lorsque les bras de levier 8 sont placés dans leur position rabattue contre le corps tubulaire 2. Ceci a pour avantage de supprimer, pour un utilisateur manipulant le tire-bouchon 1, l'inconvénient représenté par l'inévitable mouvement de rotation des bras de levier vers le haut, observé lors du vissage de la vrille dans le bouchon avec les tire-bouchons de l'état de la technique.According to the invention, the corkscrew 1 advantageously comprises means for maintaining the securing means in their inactive state when the lever arms 8 are placed in their folded position against the tubular body 2. This has the advantage of eliminating, for a user manipulating the corkscrew 1, the disadvantage represented by the inevitable rotational movement of the lever arms upwards, observed when screwing the gimlet into the cork with the corkscrews of the state of the technical.

Ainsi, grâce à cette caractéristique, avec le tire-bouchon 1 selon l'invention, un utilisateur n'a plus à ouvrir puis refermer la main avec laquelle il le maintient sur un goulot 6 d'une bouteille 7, lors du vissage de la vrille dans un bouchon, pour laisser passer les bras de levier 8, ceux-ci demeurant totalement immobiles dans leur position rabattue contre le corps 2 du tire-bouchon 1 pendant toute l'étape de vissage de la vrille 3 dans un bouchon.Thus, thanks to this characteristic, with the corkscrew 1 according to the invention, a user no longer has to open and then close the hand with which he holds it on a neck 6 of a bottle 7, when screwing the twist in a cork, to allow the lever arms 8 to pass, these remaining completely immobile in their folded position against the body 2 of the corkscrew 1 throughout the step of screwing the twist 3 into a cork.

En référence à la figure 5, dans la variante de réalisation illustrée, les moyens de solidarisation d'un bras de levier 8 avec une roue dentée 9 comportent d'une part un organe en « U » 12, présentant deux branches rectilignes 13 reliées par une branche transversale 132, et monté mobile en translation le long de l'axe longitudinal du bras de levier 8 dans un fourreau 14 dont est pourvu ledit bras de levier 8 et, d'autre part, deux encoches 15, formées radialement vis-à-vis l'une de l'autre, dans deux épaulements 90 que comporte la roue dentée 9, lesdits épaulements 90 s'étendant de part et d'autre des dents 91 de la roue dentée 9, entre la base 92 de celles-ci et une des faces 93, 94 de la roue dentée 9. De plus, il est prévu que les encoches 15 de chacune des roues dentées 9 sont toujours situées à l'extérieur des fenêtres 37 que comporte la partie supérieure du corps tubulaire 2, quelle que soit la position des roues dentées 9 par rapport à la crémaillère 4, tandis que leurs axes Y1, Y2 forment avec l'axe X du corps tubulaire 2 des angles α, β, de préférence identiques.With reference to the figure 5 , in the variant embodiment illustrated, the means for securing a lever arm 8 with a toothed wheel 9 comprise on the one hand a "U" shaped member 12, having two rectilinear branches 13 connected by a transverse branch 132, and mounted to move in translation along the longitudinal axis of the lever arm 8 in a sleeve 14 with which said lever arm 8 is provided and, on the other hand, two notches 15, formed radially opposite one of the other, in two shoulders 90 that the toothed wheel 9 comprises, said shoulders 90 extending on either side of the teeth 91 of the toothed wheel 9, between the base 92 of these and one of the faces 93, 94 of the toothed wheel 9. In addition, provision is made for the notches 15 of each of the toothed wheels 9 to always be located outside the windows 37 that comprise the upper part of the tubular body 2, whatever the position of the wheels. toothed 9 with respect to the rack 4, while their axes Y1, Y2 form with the axis X of the tubular body 2 angles α, β, preferably identical.

Plus précisément, l'organe en « U » 12 est mobile entre une position enfoncée dans le fourreau 14, correspondant à un état inactif, et une position partiellement extraite du fourreau 14, correspondant à un état actif, dans laquelle les portions supérieures 130 de chacune de ses branches rectilignes 13 sont engagées dans une des encoches 15 que comporte la roue dentée 9, et la rotation de chaque bras de levier 8 entraîne alors celle de chaque roue dentée 9, et inversement.More precisely, the "U"-shaped member 12 is movable between a position pushed into the sheath 14, corresponding to an inactive state, and a position partially extracted from the sheath 14, corresponding to an active state, in which the upper portions 130 of each of its rectilinear branches 13 are engaged in one of the notches 15 that the toothed wheel 9 comprises, and the rotation of each lever arm 8 then drives that of each toothed wheel 9, and vice versa.

Il convient de noter que le déplacement de l'organe en « U » 12 de son état actif vers son état inactif s'effectue à l'encontre d'un ressort de compression 16, ou de tout autre moyen de rappel élastique équivalent, inséré entre un premier renfoncement 18 (cf. fig. 4) formé dans un fond 17 que comporte le fourreau 14 et un second renfoncement 19 s'étendant sur la face inférieure de la branche transversale 132 dudit organe en « U » 12, de manière coaxiale au premier renfoncement 19 et de préférence dans l'axe de l'interstice 131 compris entre les deux branches rectilignes 13.It should be noted that the movement of the "U"-shaped member 12 from its active state to its inactive state takes place against a compression spring 16, or any other equivalent elastic return means, inserted between a first recess 18 (cf. fig. 4 ) formed in a bottom 17 that comprises the sheath 14 and a second recess 19 extending on the underside of the transverse branch 132 of said "U" member 12, coaxially to the first recess 19 and preferably in the axis of the gap 131 between the two rectilinear branches 13.

Par ailleurs, dans la variante de réalisation illustrée aux figures, chaque épaule d'articulation 11 comporte une paire de pattes 24, s'étendant depuis la tête de guidage, de manière symétrique de part et d'autre d'un plan contenant l'axe X du corps tubulaire 2.Furthermore, in the alternative embodiment illustrated in the figures, each hinge shoulder 11 comprises a pair of lugs 24, extending from the guide head, symmetrically on either side of a plane containing the X axis of the tubular body 2.

Chaque roue dentée 9 est logée entre une paire de pattes 24, espacées l'une de l'autre à cet effet d'une distance légèrement supérieure à l'épaisseur de ladite roue dentée 9. Par ailleurs, les deux pattes 24 d'une même paire sont elles-mêmes insérées entre une face avant 80 et une face arrière 81 que comporte chaque bras de levier 8 (cf. fig. 3).Each toothed wheel 9 is housed between a pair of tabs 24, spaced apart for this purpose by a distance slightly greater than the thickness of said toothed wheel 9. Furthermore, the two tabs 24 of a same pair are themselves inserted between a front face 80 and a rear face 81 that each lever arm 8 comprises (cf. fig. 3 ).

Les pattes 24, les roues dentées 9 ainsi que les faces avant, arrière 80, 81 des bras de levier 8 sont en outre pourvues chacune de trous coaxiaux, agencés pour permettre le passage de l'axe 10 à travers l'ensemble d'entre eux.The lugs 24, the toothed wheels 9 as well as the front and rear faces 80, 81 of the lever arms 8 are further each provided with coaxial holes, arranged to allow the passage of the axle 10 through the set of them.

Tel que visible en particulier sur la figure 5, le chant 25 de chaque patte 24 forme par ailleurs une courbe de forme particulière.As seen in particular on the figure 5 , the edge 25 of each leg 24 also forms a curve of a particular shape.

Elle comporte en effet un tronçon inférieur 26, dont les points sont situés à une distance d 0 de l'axe 10 supérieure au rayon des faces 93, 94 d'une roue dentée 9, ce tronçon inférieur 26 étant prolongé par un tronçon latéral et supérieur 27 dont les points sont situés à une distance d 1 de l'axe 10 inférieure au rayon des faces 93, 94 d'une roue dentée 9.It comprises a lower section 26, the points of which are located at a distance d 0 from the axis 10 greater than the radius of the faces 93, 94 of a toothed wheel 9, this lower section 26 being extended by a lateral section and upper 27 whose points are located at a distance d 1 from the axis 10 less than the radius of the faces 93, 94 of a toothed wheel 9.

Il convient par ailleurs de noter que lors du montage des sous-ensembles sur les épaules d'articulations 11, les roues dentées 9 sont positionnées de manière telle que les encoches 15 s'étendent en face de la portion latérale et supérieure 27 du chant 25 des pattes 24, et que les angles α, β soient sensiblement identiques.It should also be noted that when mounting the sub-assemblies on the hinge shoulders 11, the toothed wheels 9 are positioned in such a way that the notches 15 extend opposite the lateral and upper portion 27 of the edge 25 legs 24, and the angles α, β are substantially identical.

De plus, conformément à l'invention, chaque branche rectiligne 13 d'un organe en « U » 12 présente une largeur l 0 correspondant sensiblement à l'épaisseur e d'une patte 24 plus la largeur l 1 d'un épaulement 90 et donc d'une encoche 15, tandis que le fourreau 14 est formé sur chaque bras de levier 8 de préférence le long d'une face transversale 82 entre ses faces avant 80 et arrière 81, et de manière telle que la portion supérieure 130 de chaque branche rectiligne 13 d'un organe en « U » 12 s'étende, lors de la rotation d'un bras de levier 8, vis-à-vis à la fois du chant 25 de la patte 24 et de l'épaulement 90, donc l'encoche 15, considérés. L'interstice 131 s'étendant entre les deux branches rectilignes 13 présente quant à lui une dimension l 2 légèrement supérieure à l'épaisseur l 3 des dents 91 des roues dentées 9.Moreover, in accordance with the invention, each rectilinear branch 13 of a "U"-shaped member 12 has a width l 0 corresponding substantially to the thickness e of a tab 24 plus the width l 1 of a shoulder 90 and therefore a notch 15, while the sheath 14 is formed on each lever arm 8 preferably along a transverse face 82 between its front 80 and rear 81 faces, and in such a way that the upper portion 130 of each rectilinear branch 13 of a "U"-shaped member 12 extends, during the rotation of a lever arm 8, vis-à-vis both the edge 25 of the tab 24 and the shoulder 90, therefore the notch 15, considered. The gap 131 extending between the two rectilinear branches 13 has a dimension l 2 slightly greater than the thickness l 3 of the teeth 91 of the toothed wheels 9.

Conformément à une caractéristique additionnelle du tire-bouchon 1 selon l'invention, dans la variante de réalisation illustrée, les deux encoches 15 que comporte chaque roue dentée 9 sont formées vis-à-vis d'un espace compris entre deux dents 91 consécutives. Par ailleurs, la distance d 2 , comprise entre la face supérieure 133 de la branche transversale 132 de l'organe en « U » 12 et le bord supérieur 134 de ses branches rectilignes 13 est supérieure à la hauteur h d'une encoche 15 et inférieure à la distance d 3 comprise entre le fond d'une encoche 15 et le sommet 95 d'une dent 91. Il convient de noter qu'en outre, dans la variante de réalisation illustrée, le sommet 95 de chaque dent 91 est bordé par des arêtes biseautées 96, 97 (cf. fig. 5). De même, la face supérieure 133 de la branche transversale 132 de l'organe en « U » 12 est bordée par des arêtes biseautées 136.In accordance with an additional characteristic of the corkscrew 1 according to the invention, in the variant embodiment illustrated, the two notches 15 that each toothed wheel 9 has are formed opposite a space comprised between two consecutive teeth 91 . Furthermore, the distance d 2 between the upper face 133 of the transverse branch 132 of the "U" shaped member 12 and the upper edge 134 of its rectilinear branches 13 is greater than the height h of a notch 15 and less than the distance d 3 between the bottom of a notch 15 and the top 95 of a tooth 91. It should be noted that in addition, in the variant embodiment illustrated, the top 95 of each tooth 91 is by bevelled edges 96, 97 (cf. fig. 5 ). Similarly, the upper face 133 of the transverse branch 132 of the "U" member 12 is bordered by beveled edges 136.

Grâce à une telle structure du tire-bouchon 1 selon l'invention, lorsque les bras de levier 8 sont placés dans leur position rabattue contre le corps tubulaire 2, l'organe en « U » 12, solidaire de chaque bras de levier 8, est situé sous le tronçon inférieur 26 du chant 25 de chaque patte 24. Etant donné que les points de ce tronçon inférieur 26 sont situés à une distance d 0 de l'axe 10 supérieure au rayon des faces 93, 94 d'une roue dentée 9, la portion inférieure 26 de chaque patte 24 prend appui sur le bord supérieur 134 d'une branche rectiligne 13 de l'organe en « U » 12 et repousse ainsi ce dernier vers le fond 17 de son fourreau 14, en l'éloignant des épaulements 90 de la roue dentée 9 considérée, et en comprimant le ressort de compression 16.Thanks to such a structure of the corkscrew 1 according to the invention, when the lever arms 8 are placed in their folded position against the tubular body 2, the "U"-shaped member 12, integral with each lever arm 8, is located under the lower section 26 of the edge 25 of each leg 24. Given that the points of this lower section 26 are located at a distance d 0 from the axis 10 greater than the radius of the faces 93, 94 of a toothed wheel 9, the lower portion 26 of each lug 24 rests on the upper edge 134 of a rectilinear branch 13 of the "U"-shaped member 12 and thus pushes the latter towards the bottom 17 of its sheath 14, moving it away shoulders 90 of the toothed wheel 9 considered, and by compressing the compression spring 16.

En d'autres termes, dans cette position rabattue contre le corps tubulaire 2, les bras de levier 9 sont inévitablement désolidarisés des roues dentées 9 grâce à l'action de la portion inférieure 26 du chant 25 des pattes 24 sur les bords supérieurs 134 des branches rectilignes 13 de l'organe en « U » 12, empêchant tout engagement de ces dernières dans les encoches 15, l'organe en « U » étant ainsi par conséquent maintenu dans sa position inactive. Un mouvement de rotation des roues dentées 9 sous l'effet d'un déplacement de la crémaillère 4 s'effectue donc indépendamment de tout mouvement de rotation des bras de levier 8 qui demeurent avantageusement immobiles dans leur position rabattue contre le corps tubulaire 2, sans définir une gêne pour l'utilisateur.In other words, in this folded position against the tubular body 2, the lever arms 9 are inevitably separated from the toothed wheels 9 thanks to the action of the lower portion 26 of the edge 25 of the lugs 24 on the upper edges 134 of the straight branches 13 of the "U" shaped member 12, preventing any engagement of the latter in the notches 15, the member in "U" being thus consequently maintained in its inactive position. A rotational movement of the toothed wheels 9 under the effect of a movement of the rack 4 is therefore carried out independently of any rotational movement of the lever arms 8 which advantageously remain immobile in their folded position against the tubular body 2, without define an annoyance for the user.

L'utilisateur doit donc déplacer lui-même les bras de levier 8 entre leur position rabattue contre le corps tubulaire 2 et leur position écartée du corps tubulaire 2 dans laquelle ils sont situés de part et d'autre de la poignée 5.The user must therefore move the lever arms 8 themselves between their folded position against the tubular body 2 and their position separated from the tubular body 2 in which they are located on either side of the handle 5.

Au cours de cette phase, l'organe en « U » 12 solidaire de chaque bras de levier 8 effectue un mouvement de rotation antihoraire au cours duquel il s'éloigne de la portion inférieure 26 du chant 25 de chaque patte 24. Lorsqu'il arrive sous la portion latérale et supérieure 27, les bords supérieurs de ses branches rectilignes 13 sont libérés du contact avec le chant 25 de chaque patte 24, en raison du changement de profil de ce dernier par rapport à la portion inférieure 26. Ils arrivent alors en contact avec chaque épaulement 90 des roues dentées 9. Dans cette position, conformément à l'invention, le ressort de compression 16 est toujours comprimé. Puis, lorsque le bras de levier 8 poursuit sa course et parvient à hauteur des encoches 15 formées dans les épaulements 90, ces derniers n'agissent plus sur les bords supérieurs 134 des branches rectilignes 13 qui s'engagent alors dans les encoches 15 sous l'effet de la détente du ressort de compression 16, plaçant ainsi l'organe en « U » 12 dans sa position active. Dans cet état, les roues dentées 9 et les bras de levier 8 s'entraînent mutuellement en rotation.During this phase, the "U"-shaped member 12 secured to each lever arm 8 performs a counterclockwise rotational movement during which it moves away from the lower portion 26 of the edge 25 of each tab 24. When it arrives under the lateral and upper portion 27, the upper edges of its rectilinear branches 13 are released from contact with the edge 25 of each tab 24, due to the change in profile of the latter relative to the lower portion 26. They then arrive in contact with each shoulder 90 of the toothed wheels 9. In this position, in accordance with the invention, the compression spring 16 is still compressed. Then, when the lever arm 8 continues its course and reaches the height of the notches 15 formed in the shoulders 90, the latter no longer act on the upper edges 134 of the rectilinear branches 13 which then engage in the notches 15 under the effect of the relaxation of the compression spring 16, thus placing the member in "U" 12 in its active position. In this state, the toothed wheels 9 and the lever arms 8 drive each other in rotation.

Afin d'atteindre l'ensemble des objectifs fixés en préambule, il a par ailleurs été prévu de conférer au corps tubulaire 2 une forme tronconique dans laquelle le diamètre d 4 de sa portion inférieure 20 est supérieur au diamètre d 5 de sa portion médiane 22. De plus, dans la variante de réalisation illustrée, la paroi périphérique du corps tubulaire 2 comporte deux lumières longitudinales 135 s'étendant l'une en face de l'autre, entre les deux épaules d'articulation 11, depuis la tête de guidage 21 jusqu'au bord inférieur 28 du corps tubulaire 2. Ces deux lumières longitudinales 135 délimitent sur le corps tubulaire 2 deux ailes longitudinales 29 (cf. fig. 6) contre chacune desquelles repose un bras de levier 8 dans sa position rabattue contre le corps tubulaire 2 (cf. fig. 1 et 2).In order to achieve all of the objectives set in the preamble, provision has also been made to give the tubular body 2 a frustoconical shape in which the diameter d 4 of its lower portion 20 is greater than the diameter d 5 of its middle portion 22. In addition, in the variant embodiment illustrated, the peripheral wall of the tubular body 2 comprises two longitudinal slots 135 extending one in front of the other, between the two hinge shoulders 11, from the guide head 21 to the lower edge 28 of the tubular body 2. These two longitudinal slots 135 delimit on the tubular body 2 two longitudinal flanges 29 (cf. fig. 6 ) against each of which rests a lever arm 8 in its folded position against the tubular body 2 (cf. fig. 1 and 2 ).

Egalement, le corps tubulaire 2, ou au moins ses deux ailes longitudinales 29, sont de préférence conçues en un matériau déformable, tel que par exemple un matériau plastique déformable ou tout matériau présentant des propriétés équivalentes.Also, the tubular body 2, or at least its two longitudinal wings 29, are preferably made of a deformable material, such as for example a deformable plastic material or any material having equivalent properties.

Par ailleurs, le corps tubulaire 2 peut encore comporter, sur chacune de ses ailes longitudinales 29, au niveau de sa portion inférieure 20, une bande 31 d'un matériau élastomère (cf. fig. 4) logée dans un renfoncement 32 (cf. fig. 6) s'étendant, sur leur face interne 35, entre le bord inférieur 28 du corps tubulaire 2 et un épaulement 33 lui-même formé entre la portion inférieure 20 et la portion médiane 22 du corps tubulaire 2.Furthermore, the tubular body 2 may also comprise, on each of its longitudinal flanges 29, at its lower portion 20, a strip 31 of an elastomeric material (cf. fig. 4 ) housed in a recess 32 (cf. fig. 6 ) extending, on their inner face 35, between the lower edge 28 of the tubular body 2 and a shoulder 33 itself formed between the lower portion 20 and the middle portion 22 of the tubular body 2.

Les deux bandes 31 d'un matériau élastomère définissent avantageusement des moyens de blocage en rotation du tire-bouchon 1 par rapport à un goulot 6 d'une bouteille 7.The two strips 31 of an elastomeric material advantageously define means for locking the corkscrew 1 in rotation with respect to a neck 6 of a bottle 7.

Par ailleurs, le corps tubulaire 2 du tire-bouchon 1 a également pour spécificité de présenter une longueur telle que la vrille 3 demeure intégralement logée à l'intérieur de sa portion inférieure 20 dans la position basse de la crémaillère 4, ce qui permet d'éviter tout risque de blessure intempestive pour un utilisateur et de rayures inopportunes d'un plan sur lequel le tire-bouchon 1 aurait été posé verticalement. Afin d'améliorer la stabilité d'un tel positionnement, le bord inférieur 28 du corps tubulaire 2 présente en outre une face d'appui 34 sur un plan s'étendant entre la face interne 35 et la face externe 36 de sa paroi périphérique.Furthermore, the tubular body 2 of the corkscrew 1 also has the specificity of having a length such that the auger 3 remains fully housed inside its lower portion 20 in the low position of the rack 4, which allows avoid any risk of untimely injury to a user and inappropriate scratching of a plane on which the corkscrew 1 would have been placed vertically. In order to improve the stability of such positioning, the lower edge 28 of the tubular body 2 also has a bearing face 34 on a plane extending between the internal face 35 and the external face 36 of its peripheral wall.

Le tire-bouchon 1 selon l'invention a également pour avantage de comporter des moyens de signalisation de la profondeur de vissage de la vrille 3 dans le bouchon d'une bouteille 7.The corkscrew 1 according to the invention also has the advantage of comprising means for signaling the screwing depth of the auger 3 in the cork of a bottle 7.

Ceux-ci peuvent par exemple être définis par au moins un repère, tel qu'un trait de couleur, apposé sur la crémaillère 4, représentatif d'une profondeur de vissage de la vrille 3 dans un bouchon à ne pas dépasser. Un tel repère, apparaissant inévitablement dans les lumières longitudinales 135 du corps 2 lors du vissage de la vrille 3 dans un bouchon, et par conséquent lors du mouvement de translation vers sa position basse de ladite crémaillère 4, constitue ainsi un signal visuel indiquant à l'utilisateur qu'il a atteint une profondeur de vissage au-delà de laquelle un risque d'effritement du bouchon, synonyme de morceaux de liège dans le vin, est à craindre.These can for example be defined by at least one marker, such as a colored line, affixed to the rack 4, representing a screwing depth of the auger 3 in a stopper not to be exceeded. Such a marker, inevitably appearing in the longitudinal slots 135 of the body 2 when the auger 3 is screwed into a stopper, and consequently during the translation movement towards its low position of the said rack 4, thus constitutes a visual signal indicating to the user that he has reached a screwing depth beyond which there is a risk of cork crumbling, synonymous with pieces of cork in the wine.

La mise en œuvre du tire-bouchon 1 selon l'invention et ses avantages seront décrits à présent.The implementation of the corkscrew 1 according to the invention and its advantages will now be described.

Lorsqu'un utilisateur souhaite extraire un bouchon du goulot 6 d'une bouteille 7 au moyen du tire-bouchon 1 selon l'invention, il place tout d'abord celui-ci dans son état illustré à la figure 1, dans lequel la crémaillère 4 est dans sa position haute et les deux bras de levier 8 sont dans leur position rabattue contre les deux ailes longitudinales 29 du corps tubulaire 2. Comme il a été décrit ci-dessus, dans cet état, chaque organe en « U » 12 est placé dans son état inactif, les bras de levier 8 sont donc désolidarisés des roues dentées 9.When a user wishes to extract a cork from the neck 6 of a bottle 7 by means of the corkscrew 1 according to the invention, he first places the latter in its state illustrated in figure 1 , in which the rack 4 is in its high position and the two lever arms 8 are in their folded position against the two longitudinal flanges 29 of the tubular body 2. As described above, in this state, each member in "U" 12 is placed in its inactive state, the lever arms 8 are therefore separated from the toothed wheels 9.

Puis, l'utilisateur positionne le tire-bouchon 1 sur le goulot 6 d'une bouteille 7. Cette étape est facilitée par la forme particulière du corps tubulaire 2 et l'utilisation d'un matériau déformable pour sa conception. La présence des bandes 31 d'un matériau élastomère permet en outre d'éviter tout risque de rotation du tire-bouchon 1 pendant le vissage de la vrille 3 dans un bouchon, et permet d'économiser à l'utilisateur la fourniture d'un effort pour éviter une telle rotation.Then, the user positions the corkscrew 1 on the neck 6 of a bottle 7. This step is facilitated by the particular shape of the tubular body 2 and the use of a deformable material for its design. The presence of the strips 31 of an elastomeric material also makes it possible to avoid any risk of rotation of the corkscrew 1 during the screwing of the auger 3 into a cork, and saves the user the supply of a effort to avoid such rotation.

L'utilisateur maintient ensuite d'une main la bouteille 7 au niveau de son goulot 6 par le biais de la partie inférieure du corps 2 sans toucher la bouteille 7. La bouteille 7 peut également être posée sur un plan horizontal. Dans ce cas, l'utilisateur n'a pas besoin de supporter son poids. Quoiqu'il en soit, de sa main libre il peut ensuite entreprendre le vissage de la vrille 3 dans le bouchon à extraire, moyennant un actionnement de la poignée 5. Ceci provoque un déplacement de la crémaillère 4 vers sa position basse qui s'accompagne d'un mouvement de rotation antihoraire des roues dentées 9.The user then holds the bottle 7 with one hand at its neck 6 through the lower part of the body 2 without touching the bottle 7. The bottle 7 can also be placed on a horizontal plane. In this case, the user does not need to support his weight. Be that as it may, with his free hand he can then undertake the screwing of the auger 3 into the cork to be extracted, by means of an actuation of the handle 5. This causes a displacement of the rack 4 towards its low position which is accompanied of a counter-clockwise rotational movement of the toothed wheels 9.

Lorsque l'utilisateur estime que la profondeur de vissage souhaitée de la vrille 3 dans le bouchon est atteinte, par exemple suite à l'apparition dans une lumière longitudinale 135 d'un repère correspondant apposé sur la crémaillère 4, il relâche la poignée 5. Conformément à l'invention, les encoches 15 des roues dentées 9 s'étendent alors de part et d'autre de la portion supérieure 21 du corps tubulaire 2 et de manière telle que leur axe Y1, Y2 soit sensiblement parallèle à l'axe X du corps tubulaire 2. En somme, dans cette position, les axes Y1, Y2 des encoches 15 forment un angle de l'ordre de 180° avec l'axe longitudinal de chaque bras de levier 8.When the user estimates that the desired screwing depth of the auger 3 in the cap has been reached, for example following the appearance in a longitudinal slot 135 of a corresponding mark affixed to the rack 4, he releases the handle 5. In accordance with the invention, the notches 15 of the toothed wheels 9 then extend on either side of the upper portion 21 of the tubular body 2 and in such a way that their axis Y1, Y2 is substantially parallel to the axis X of the tubular body 2. In short, in this position, the axes Y1, Y2 of the notches 15 form an angle of the order of 180° with the longitudinal axis of each lever arm 8.

La bouteille 7 étant posée sur un plan horizontal, l'utilisateur utilise alors ses deux mains pour relever les deux bras de levier 8 et les placer progressivement dans leur position écartée du corps tubulaire 2, dans laquelle ils s'étendent de part et d'autre de la poignée 5. Ce mouvement de rotation des bras de levier 8 s'effectue indépendamment de toute rotation des roues dentées 9, toujours désolidarisées des bras de levier 8.The bottle 7 being placed on a horizontal plane, the user then uses both hands to raise the two lever arms 8 and place them gradually in their position spaced from the tubular body 2, in which they extend on both sides. the other of the handle 5. This rotational movement of the lever arms 8 takes place independently of any rotation of the toothed wheels 9, which are always disconnected from the lever arms 8.

Comme il a été décrit ci-dessus, lorsque ces derniers parviennent à hauteur des encoches 15, les bords supérieurs des branches rectilignes 13 de chaque organe en « U » s'engagent dans les encoches 15 et solidarisent ainsi chaque bras de levier 8 à une roue dentée 9. Dans cette position, l'axe longitudinal de chaque bras de levier forme un angle de l'ordre de 0° avec l'axe Y1, Y2 d'une encoche 15.As described above, when the latter reach the height of the notches 15, the upper edges of the rectilinear branches 13 of each "U" member engage in the notches 15 and thus secure each lever arm 8 to a toothed wheel 9. In this position, the longitudinal axis of each lever arm forms an angle of the order of 0° with the axis Y1, Y2 of a notch 15.

L'utilisateur peut ensuite extraire intégralement le bouchon du goulot 6 d'un seul mouvement, consistant à replacer, à l'aide de ses deux mains, les deux bras de levier 8 dans leur position rabattue contre le corps tubulaire 2.The user can then completely extract the stopper from the neck 6 in a single movement, consisting in replacing, using both hands, the two lever arms 8 in their folded position against the tubular body 2.

Lors de ce mouvement, chaque branche rectiligne 13 de l'organe en « U » 12, placé dans sa position active, appuie sur une paroi d'une encoche 15. De plus, une arête biseautée 136 de la face supérieure 133 de la branche transversale 132 de l'organe en « U » appuie sur une arête biseautée 96 que comporte chaque sommet d'une dent 91. Le mouvement de rotation des bras de levier 8 induit par conséquent un mouvement de rotation à 180° dans le sens horaire des roues dentées 9, provoquant un déplacement jusqu'à sa position haute de la crémaillère 3. Une telle course permet donc avantageusement une extraction complète d'un seul mouvement des bras de levier 8, d'un bouchon logé dans un goulot 6. Une fois extrait, le bouchon s'étend dans la portion intermédiaire 22 du corps tubulaire 2.During this movement, each rectilinear branch 13 of the "U"-shaped member 12, placed in its active position, presses against a wall of a notch 15. In addition, a bevelled edge 136 of the upper face 133 of the branch transverse 132 of the "U" member presses on a bevelled edge 96 that each vertex of a tooth 91 has. The rotational movement of the lever arms 8 consequently induces a 180° toothed wheels 9, causing the rack 3 to move to its high position. extracted, the stopper extends into the intermediate portion 22 of the tubular body 2.

A ce propos, la face interne 35 de ce dernier présente également sur chaque aile longitudinale 29, un deuxième épaulement 38, contre lequel la face supérieure d'un bouchon vient en butée après son extraction d'un goulot 6. Pour libérer le bouchon du corps du tire-bouchon 2 et de la vrille 3, il suffit ainsi de dévisser cette dernière au moyen de la poignée 5, tout en rapprochant les deux bras de levier 8 du corps tubulaire 2 l'un de l'autre, afin de pincer le bouchon et d'éviter sa rotation. La forme particulière du corps tubulaire 2 permet ensuite au bouchon de tomber de lui-même, dès lors que l'utilisateur cesse d'agir sur les deux bras de levier 8.In this regard, the inner face 35 of the latter also has on each longitudinal flange 29, a second shoulder 38, against which the upper face of a stopper comes into abutment after its extraction from a neck 6. To release the stopper from the body of the corkscrew 2 and of the gimlet 3, it is thus sufficient to unscrew the latter by means of the handle 5, while bringing the two lever arms 8 of the tubular body 2 closer to each other, in order to pinch the cap and prevent it from rotating. The form particular feature of the tubular body 2 then allows the stopper to fall off by itself, as soon as the user stops acting on the two lever arms 8.

Tel qu'il ressort clairement de ce qui précède, le tire-bouchon 1 selon l'invention permet avantageusement de réduire de manière significative le nombre d'étapes nécessaires au débouchage d'une bouteille par rapport à un tire-bouchon à double levier de l'état de la technique décrit dans la partie introductive.As is clear from the foregoing, the corkscrew 1 according to the invention advantageously makes it possible to significantly reduce the number of steps necessary for uncorking a bottle compared to a corkscrew with a double lever of the state of the art described in the introductory part.

Par ailleurs, il se distingue par une ergonomie parfaite lors de l'insertion de la vrille dans le bouchon grâce au caractère déformable du corps tubulaire 2.Furthermore, it is distinguished by perfect ergonomics when inserting the auger into the cork thanks to the deformable nature of the tubular body 2.

Il permet également d'effectuer toute l'étape de vissage de la vrille 3 dans un bouchon sans avoir à le tenir en même temps que la bouteille 7.It also makes it possible to carry out the entire step of screwing the twist 3 into a cork without having to hold it at the same time as the bottle 7.

Un vissage de la vrille 3 dans le bouchon sur toute la course indépendamment de toute rotation des bras de levier 8 est également possible, ce qui permet d'améliorer la manipulation du tire-bouchon selon l'invention par rapport aux tire-bouchons de l'art antérieur.A screwing of the auger 3 in the cork over the entire stroke independently of any rotation of the lever arms 8 is also possible, which makes it possible to improve the handling of the corkscrew according to the invention compared to the corkscrews of the prior art.

La présence des moyens d'indication de la profondeur de vissage de la vrille 3 permet d'éviter toute introduction de liège dans le vin contenu dans la bouteille en cours de débouchage.The presence of the means for indicating the screwing depth of the auger 3 makes it possible to avoid any introduction of cork into the wine contained in the bottle during uncorking.

Par ailleurs le tire-bouchon 1 selon l'invention autorise l'extraction en une seule étape des bouchons de longueur importante (supérieur à 40 mm), et présente une structure permettant d'assurer un dévissage sécurisé de la vrille 3 en fin de la manipulation.Furthermore, the corkscrew 1 according to the invention allows the extraction in a single step of corks of significant length (greater than 40 mm), and has a structure making it possible to ensure secure unscrewing of the twist 3 at the end of the handling.
