Abstract

The invention concerns an automatic corkscrew comprising a tubular body (1) receiving a mobile slide (10, 10') consisting of at least two parts, namely a head (12, 12') and a nut (14, 14'), including at its base a helical extraction screw (22, 22') wherein one of the slide (10, 10') two parts (12, 12'-14, 14') is provided with locking means (20, 19, 43) capable of co-operating with matching receiving means (19, 20, 43) arranged on the other part (14, 12) so as to interlock, when activated, said two parts (12, 14). Said corkscrew further comprises unlocking means (30, 32, 47) acting, in inoperative position, on the locking means (20, 19, 43) to disengage the slide (10) two parts (12, 14). Said corkscrew is characterised in that it comprises means for disconnecting (34, 34', 50) the unlocking means (30, 32, 47) so as to interlock, when they are activated, the head (12, 12') and the nut (14, 14').

Description

La présente invention concerne un tire-bouchon et plus précisément un tire-bouchon de type automatique.The present invention relates to a corkscrew and more precisely an automatic type corkscrew.

Les tire-bouchons de type automatique sont des appareils qui permettent, par l'action sur un ou plusieurs organes de commande, d'effectuer les différentes opérations successives d'introduction d'une vis d'extraction à l'intérieur du bouchon, d'extraction de ce dernier du goulot de la bouteille et d'expulsion du bouchon extrait.Automatic type corkscrews are devices that allow, by action on one or more control bodies, to perform the different successive operations of inserting a screw extraction inside the cap, extraction of this last of the bottle neck and expulsion of the extract cap.

La plupart des tire-bouchons automatiques de l'état antérieur de la technique et notamment celui suivant le brevet EP-A-0.818.414 sont essentiellement constitués d'un corps, ou bâti, comportant des moyens de guidage d'une tête mobile, dont le déplacement est assuré par des organes de commande, et qui est pourvue d'une vis d'extraction montée libre en rotation et fixe en translation sur cette tête. Ces tire-bouchons comprennent également un écrou, lui-même monté mobile en translation sur le corps dans lequel la vis d'extraction est vissée. Dans de tels dispositifs, lors de la phase d'introduction de la vis d'extraction dans le bouchon, on solidarise l'écrou du bâti et l'on déplace la tête par rapport à celui-ci, ce qui a pour effet de provoquer la rotation de la vis d'extraction dans l'écrou et sa pénétration à l'intérieur du bouchon. Lors de la phase suivante, qui est la phase d'extraction, on fait en sorte de solidariser la tête de l'écrou à l'aide de moyens de verrouillage puis on effectue un déplacement en translation de l'écrou et de la tête, ce qui a pour effet d'une part d'empêcher toute rotation de la vis d'extraction et d'autre part d'entraíner le bouchon hors du goulot de la bouteille. On déplace ensuite, dans un troisième temps, la tête et l'écrou vers le bas du corps et, enfin, dans un quatrième temps, et après avoir immobilisé l'écrou et l'avoir séparé de la tête en agissant à l'aide de leviers sur les moyens de verrouillage on éloigne la tête de ce dernier, ce qui a pour effet de mettre en rotation la vis d'extraction et d'extraire celle-ci du bouchon assurant ainsi la libération de ce dernier.Most automatic corkscrews the prior art and in particular that according to patent EP-A-0.818.414 are essentially made up of a body, or frame, comprising means of guiding a moving head, whose movement is ensured by control members, and which is provided with a screw extraction mounted free in rotation and fixed in translation on this head. These corkscrews include also a nut, itself mounted movable in translation on the body in which the extraction screw is screwed. In such devices, during the introduction phase of the extraction screw in the cap, it is secured the frame nut and the head is moved relative to this, which has the effect of causing the rotation of the extraction screw in the nut and its penetration at inside the cap. In the next phase, which is the extraction phase, we ensure that the head of the nut using locking means and then performs a translational movement of the nut and the on the one hand, which prevents any rotation of the extraction screw and on the other hand to drive the cap out of the neck of the bottle. We then moves, in a third step, the head and the nut down the body and finally in a fourth time, and after immobilizing the nut and having separated it of the head by acting using levers on the means the head is moved away from the latter, which has the effect of rotating the extraction screw and extract it from the cap thus ensuring the release of the latter.

On connaít différents types de tire-bouchons mettant en oeuvre un tel principe de fonctionnement. Ces tire-bouchons, qui sont à l'usage par exemple des collectivités, sont la plupart du temps des dispositifs encombrants destinés à être fixés sur un plan de travail.We know different types of corkscrews implementing such an operating principle. These corkscrews, which are used, for example, communities, are mostly devices bulky items intended to be fixed on a work surface.

On a également proposé des tire-bouchons automatiques fonctionnant suivant ce même principe et qui sont à l'usage des particuliers. Ces modèles ainsi que celui suivant le brevet EP-A-0.818.414 font appel à des mécanismes de serrage du tire-bouchon sur le goulot de la bouteille au moyen de bras de levier. Il s'ensuit que l'utilisateur est ainsi contraint d'effectuer des efforts n'ayant pas une direction unique, c'est-à-dire qu'il est contraint d'une part de serrer fortement le goulot de la bouteille au moyen des leviers et d'autre part d'exercer un effort perpendiculaire à celui-ci de bas en haut et inversement au cours du cycle de mise en oeuvre de ce tire-bouchon.We also proposed corkscrews automatic operating on the same principle and which are for the use of individuals. These models as well as that according to patent EP-A-0.818.414 use corkscrew tightening mechanisms on the neck of the bottle by means of lever arms. It follows that the user is thus forced to make efforts not having a single direction, that is, it is forced on the one hand to tighten the neck of the bottle by means of the levers and secondly to exercise an effort perpendicular to it from bottom to top and conversely during the implementation cycle of this corkscrew.

Par ailleurs, en raison de la présence des leviers de maintien du tire-bouchon sur le goulot des bouteilles, ce type d'appareil est la plupart du temps d'un encombrement relativement important puisque son volume s'étend essentiellement suivant deux dimensions.Furthermore, due to the presence of the levers holding the corkscrew on the neck of the bottles, this type of device is mostly a relatively large size since its volume essentially extends along two dimensions.

La présente invention a pour but de proposer un tire-bouchon de type automatique, d'un encombrement réduit s'étendant essentiellement suivant une direction préférentielle, et d'un prix de revient réduit.The object of the present invention is to provide a automatic type corkscrew, compact extending essentially in one direction preferential, and a reduced cost price.

La présente invention a ainsi pour objet un tire-bouchon de type automatique comportant un corps tubulaire dont la surface interne forme un guide d'un tiroir monté mobile en translation suivant l'axe longitudinal dudit corps entre une position haute et une position basse, ce tiroir étant constitué au moins de deux parties, à savoir une tête et un écrou, la tête étant solidaire de moyens de préhension et comportant à sa base une vis d'extraction montée libre en rotation et fixe en translation par rapport à la tête, l'écrou, recevant la vis d'extraction, de façon qu'au cours d'un déplacement relatif de la tête par rapport à l'écrou la vis d'extraction effectue un mouvement de rotation, dans lequel l'une des deux dites parties du tiroir est pourvue de moyens de verrouillage aptes à coopérer avec des moyens de réception complémentaires disposés sur l'autre partie, de façon à assurer, lorsqu'ils sont activés, la solidarisation des deux dites parties, caractérisé en ce que ce tire-bouchon comporte en outre des moyens de déverrouillage agissant, en position de repos du tire-bouchon, sur les moyens de verrouillage afin de libérer les deux parties du tiroir, et des moyens de déconnexion des moyens de déverrouillage permettant, lorsqu'ils sont activés, d'assurer la solidarisation de la tête et de l'écrou.The present invention thus relates to a corkscrew automatic type comprising a tubular body the internal surface of which forms a guide for a mounted drawer movable in translation along the longitudinal axis of said body between a high position and a low position, this drawer consisting of at least two parts, namely a head and a nut, the head being integral with means of gripping and comprising at its base an extraction screw freely mounted in rotation and fixed in translation by report to the head, the nut, receiving the extraction screw, so that during a relative movement of the head relative to the nut the extraction screw performs a rotational movement, in which one of the two said parts of the drawer is provided with locking means able to cooperate with reception means complementary arranged on the other part, so that ensure, when activated, the joining of two said parts, characterized in that this corkscrew further comprises unlocking means acting in the position of rest of the corkscrew, on the locking means so to release the two parts of the drawer, and means for disconnecting means for unlocking allowing, when activated, securing the head and the nut.

Le corps du tire-bouchon sera préférablement formé de deux demi-coquilles tubulaires et comprendra au moins une rainure longitudinale, et chacun des éléments du tiroir comportera au moins un téton apte à se déplacer dans cette rainure.The body of the corkscrew will preferably be formed of two tubular half-shells and will include at least a longitudinal groove, and each of the elements of the drawer will have at least one nipple able to move in this groove.

Dans un mode de mise en oeuvre du tire-bouchon suivant l'invention, l'écrou est formé de deux parties, à savoir,

  • une douille comportant, à sa partie supérieure, des moyens d'encliquetage aptes à coopérer dans une position angulaire déterminée, avec des moyens de butée disposés à la base de l'écrou et qui assurent, dans cette position, leur solidarisation en translation longitudinale et, dans une autre position angulaire, leur liberté en translation,
  • un élément d'écrou qui est monté mobile à rotation à la base de la douille.
In one embodiment of the corkscrew according to the invention, the nut is formed from two parts, namely,
  • a sleeve comprising, at its upper part, latching means capable of cooperating in a determined angular position, with stop means arranged at the base of the nut and which ensure, in this position, their connection in longitudinal translation and , in another angular position, their freedom in translation,
  • a nut element which is rotatably mounted at the base of the socket.

Préférentiellement la base de chaque rainure longitudinale s'ouvre sur une rainure transversale, apte à recevoir le téton de la douille, sous l'effet de moyens de sollicitation élastiques, lorsque la douille se trouve en position basse dans le corps.Preferably the base of each groove longitudinal opens on a transverse groove, suitable for receive the nipple of the socket, under the effect of means of elastic stress, when the sleeve is in low position in the body.

Par ailleurs les moyens de butée réalisés sur la tête peuvent être constitués d'une part d'au moins une butée radiale s'étendant vers l'extérieur à partir de la base d'une portion cylindrique et d'autre part d'une zone libre de butée, les moyens d'encliquetage comprenant au moins une butée radiale s'étendant vers l'intérieur et apte, lorsque le téton solidaire de la douille est en alignement longitudinal avec le téton solidaire de l'élément d'écrou, à coopérer avec la butée de la tête de façon à assurer la solidarisation en translation longitudinale de ces deux éléments.Furthermore, the stop means made on the head may consist of a share of at least one radial stop extending outward from the base of a cylindrical portion and on the other hand of a zone free of abutment, the latching means comprising at minus a radial stop extending inwards and suitable, when the stud integral with the socket is in longitudinal alignment with the stud attached to the nut element, to cooperate with the stop of the head of so as to secure the connection in translation longitudinal of these two elements.

Dans un mode de mise en oeuvre de l'invention la zone libre de butée est disposée de façon telle que, lorsque le téton solidaire de la douille est appliqué au fond de la rainure transversale par les moyens élastiques, la butée radiale est en alignement longitudinal avec la zone libre, permettant ainsi la désolidarisation en translation longitudinale de la tête et de l'écrou. Les moyens de commande de déconnexion des moyens de déverrouillage pourront être mobiles en translation longitudinale entre une position abaissée et une position relevée, et comporter au moins un pan incliné, par rapport à l'axe longitudinal du tire-bouchon, qui est apte, lorsqu'il est en position relevée, à entrer en contact avec le téton de la douille afin de l'amener en alignement longitudinal avec le téton de l'élément d'écrou. Préférentiellement ces moyens de commande de déconnexion seront maintenus au repos, en position basse, par des moyens élastiques et seront en mesure d'être amenés en position haute par appui de ces moyens sur le goulot d'une bouteille.In one embodiment of the invention the free stop area is arranged so that, when the stud attached to the socket is applied to the bottom of the transverse groove by elastic means, the radial stop is in longitudinal alignment with the free zone, thus allowing the separation in longitudinal translation of the head and the nut. The disconnection control means means of unlocking can be mobile in translation longitudinal between a lowered position and a position raised, and have at least one inclined face, relative to to the longitudinal axis of the corkscrew, which is suitable, when in the raised position, to make contact with the nipple of the socket in order to bring it into alignment longitudinal with the nipple of the nut element. Preferably these disconnection control means will be kept at rest, in the low position, by elastic means and will be able to be brought in high position by pressing these means on the neck of a bottle.

La figure 14 est une vue en perspective éclatée de l'exemple de mise en oeuvre d'un tire-bouchon suivant l'invention représenté sur les figures 10 à 13.Figure 14 is an exploded perspective view of the following example of implementation of a corkscrew the invention shown in Figures 10 to 13.

Dans un premier mode de mise en oeuvre représenté sur les figures 1 à 7 le tire-bouchon suivant l'invention est constitué d'un corps tubulaire 1 formé de deux coquilles 2. Ces dernières sont liées en translation par des tétons 6 qui prennent place dans des trous correspondants de celles-ci. Les deux coquilles 2 une fois assemblées sont enfilées dans un fourreau 4 qui assure le maintien de l'ensemble.In a first embodiment shown in Figures 1 to 7 the corkscrew according to the invention consists of a tubular body 1 formed of two shells 2. These are linked in translation by nipples 6 which take place in holes correspondents of these. The two shells 2 once assemblies are threaded into a sheath 4 which ensures the maintenance of the whole.

Les deux coquilles 2 sont creusées d'une rainure longitudinale 8 de section droite rectangulaire qui est destinée à assurer le guidage en translation d'un tiroir parallélépipédique 10 formé de deux parties, à savoir une tête 12 et un écrou 14. L'écrou 14 est de forme sensiblement cubique et se prolonge vers le haut par deux languettes 16 qui sont destinées à venir prendre place dans des évidements respectifs 18 de forme correspondante creusés dans la tête 12. Les languettes 16 sont percées à leur partie supérieure de trous respectifs 19 destinés à recevoir des ergots opposés 20 qui sont montés télescopiques sur la tête 12, sous l'action d'un ressort de compression 21 disposé entre ces derniers. On assure ainsi la solidarisation des deux parties constituant le tiroir 10 à savoir la tête 12 et l'écrou 14.The two shells 2 are hollowed out with a groove longitudinal 8 of rectangular cross section which is intended to provide translational guidance for a drawer parallelepiped 10 formed of two parts, namely a head 12 and a nut 14. The nut 14 is shaped substantially cubic and extends upward by two tabs 16 which are intended to come to take place in respective recesses 18 of corresponding shape hollowed out in the head 12. The tongues 16 are drilled at their upper part of respective holes 19 intended for receive opposite lugs 20 which are mounted telescopic on the head 12, under the action of a spring compression 21 disposed therebetween. We assure thus the joining of the two parts constituting the drawer 10 namely the head 12 and the nut 14.

La partie supérieure de la tête 12 est reliée à des moyens de préhension 7, et sa partie inférieure est creusée d'un orifice 13 destiné à recevoir des moyens de suspension et de maintien d'une vis d'extraction 22. Ces moyens de suspension sont constitués d'une douille 15 et d'un écrou 25 qui autorisent à la fois une libre rotation de la vis 22 par rapport à la tête 12 et son maintien dans le sens longitudinal. La partie inférieure de la vis 22 traverse longitudinalement l'écrou 14 qui, à cet effet, est percé d'un trou de forme appropriée à la forme hélicoïdale de la vis 22, de façon à former écrou. Cependant ainsi que représenté sur les figures 4 et 6, l'écrou est préférablement constitué par un trou central et longitudinal 26 d'un diamètre voisin du diamètre extrême de la vis 22 par deux pions cylindriques et parallèles 24 dont les axes sont perpendiculaires à l'axe longitudinal yy' du tire-bouchon et sont décalés l'un de l'autre à la fois dans le sens vertical et dans le sens transversal.The upper part of the head 12 is connected to gripping means 7, and its lower part is hollowed out with an orifice 13 intended to receive means for suspension and holding of an extraction screw 22. These suspension means consist of a socket 15 and a nut 25 which allow both free rotation of the screw 22 relative to the head 12 and its maintenance in the longitudinal direction. The lower part of the screw 22 longitudinally passes through the nut 14 which, for this purpose, is drilled with a hole suitable for the shape helical screw 22, so as to form a nut. However, as shown in FIGS. 4 and 6, the nut is preferably formed by a central hole and longitudinal 26 with a diameter close to the diameter end of screw 22 by two cylindrical pins and parallels 24 whose axes are perpendicular to the axis longitudinal yy 'of the corkscrew and are offset one of each other both vertically and vertically transverse.

Le fond de la partie supérieure de chaque rainure 8 est creusé d'un évidement 28 dans lequel est fixée, par sa partie supérieure, une lame élastique 30 dont la base comporte un téton 32 d'un diamètre et d'une longueur tels qu'ils lui permettent de prendre place à l'intérieur du trou 19 de la languette 16. La lame 30 sera telle, qu'elle possède une raideur suffisante pour déplacer le téton 32 en direction de l'axe yy' du tire-bouchon avec une force d'application supérieure à celle du ressort 21 de façon que, en position de repos de l'appareil, les tétons 32 repoussent les ergots 20 à l'encontre du ressort 21 et prennent place dans le trou 19 de la languette 16, assurant ainsi d'une part l'immobilisation de l'écrou 14 par rapport au corps 1 du tire-bouchon, et d'autre part le déverrouillage de celui-ci d'avec la tête 12, ainsi que représenté sur le côté gauche de la figure 4.The bottom of the top of each groove 8 is hollowed out by a recess 28 in which is fixed, by its upper part, an elastic blade 30 whose base has a nipple 32 with a diameter and a length such that they allow it to take place inside the hole 19 of the tongue 16. The blade 30 will be such that it has sufficient stiffness to move the nipple 32 towards the yy 'axis of the corkscrew with force of higher application than that of spring 21 so that, in the device's rest position, the pins 32 push the lugs 20 against the spring 21 and take place in the hole 19 of the tongue 16, thus ensuring on the one hand the immobilization of the nut 14 relative to the body 1 of the corkscrew, and on the other hand the unlocking it from the head 12, as well as shown on the left side of Figure 4.

Chacune des deux coquilles 2 est creusée à sa partie inférieure d'une rainure interne longitudinale 33, ces deux rainures internes étant destinées à recevoir deux glissières respectives 34 qui sont disposées à la partie supérieure d'un élément tubulaire 36 destiné à recevoir le goulot 3 de la bouteille dont on souhaite extraire le bouchon 5 avec celui du corps 1 du tire-bouchon. Each of the two shells 2 is hollowed out at its lower part of a longitudinal internal groove 33, these two internal grooves being intended to receive two respective slides 34 which are arranged at the part upper part of a tubular element 36 intended to receive the neck 3 of the bottle from which we wish to extract the cap 5 with that of the body 1 of the corkscrew.

Les deux glissières 34 comportent, sur leur face externe, une butée 37 destinée à limiter leur course à l'intérieur de la rainure 33 et qui se déplacent dans des évidements 38 prévus dans les coquilles 2.The two slides 34 have, on their face external, a stop 37 intended to limit their travel to inside the groove 33 and which move in recesses 38 provided in the shells 2.

Un ressort de compression 35 est disposé entre la base du corps 1 et la partie supérieure de l'élément tubulaire 36, ce ressort de compression ayant pour effet d'éloigner l'élément tubulaire 36 du corps 1.A compression spring 35 is disposed between the base of body 1 and the top of the element tubular 36, this compression spring having the effect move the tubular element 36 away from the body 1.

La partie inférieure des lames 30 et la partie supérieure externe en regard des glissières 34 sont biseautées de façon que, lorsque l'on déplace les glissières 34 vers le haut à l'encontre de l'action du ressort de compression 35, la partie biseautée de chaque glissière vient en contact avec la partie correspondante biseautée de la languette 30 avec pour effet, ainsi que représenté sur la moitié droite de la figure 4, de repousser celle-ci vers l'extérieur ce qui permet aux ergots 20 de reprendre leur place à l'intérieur des trous respectifs 19 des languettes 16, ce qui a pour effet de solidariser les deux parties du tiroir 10, à savoir la tête 12 et l'écrou 14.The lower part of the blades 30 and the part external upper opposite the slides 34 are bevelled so that when we move the slides 34 upwards against the action of the compression spring 35, the bevelled part of each slide comes into contact with the corresponding part beveled tongue 30 with the effect, as well as represented on the right half of figure 4, of push it outwards which allows pins 20 to resume their place inside the holes respective 19 of the tabs 16, which has the effect of secure the two parts of the drawer 10, namely the head 12 and nut 14.

Afin d'assurer le centrage de goulots de bouteilles 3 de diamètres différents, l'élément tubulaire 36 est pourvu d'une pince déformable 40. Cette pince est constituée d'une première partie, ou base 40a, de forme cylindrique qui est fixée sur la face interne de l'élément tubulaire 36 et d'une seconde partie supérieure 40b de forme tronconique, qui est fendue longitudinalement d'une pluralité de rainures 41, de façon à former entre elles des languettes déformables et élastiques 39. Lorsque l'on met en place le goulot 3 d'une bouteille dans la pince 40, ainsi que représenté sur la figure 6b, celui-ci vient en appui sur les languettes 39 avec pour effet de les déformer, si bien que par réaction celles-ci assurent un centrage automatique du goulot 3.In order to ensure the centering of bottlenecks bottles 3 of different diameters, the tubular element 36 is provided with a deformable clamp 40. This clamp is consisting of a first part, or base 40a, of form cylindrical which is fixed on the internal face of the element tubular 36 and a second upper part 40b of frustoconical shape, which is split longitudinally of a plurality of grooves 41, so as to form therebetween deformable and elastic tabs 39. When one places the neck 3 of a bottle in the clamp 40, as shown in Figure 6b, it comes in support on the tabs 39 with the effect of deform, so that by reaction these ensure a automatic centering of the neck 3.

Dans ces conditions, le fonctionnement du tire-bouchon automatique suivant l'invention s'établit ainsi que décrit ci-après, et représenté sur les dessins schématiques des figures la à le et les dessins de détail des figures 2 à 6.Under these conditions, the operation of the corkscrew automatic according to the invention is thus established as described below, and shown in the drawings schematics of figures la to the and detail drawings Figures 2 to 6.

On met tout d'abord le tire-bouchon dans la position de départ représentée sur la figure la, en exerçant une traction sur l'élément de préhension 7, ce qui a pour effet de désolidariser la tête 12 de l'écrou 14. En effet dans cette position, le ressort de compression 35 éloigne l'élément tubulaire 36 de la base du corps 1 et les glissières 34 se trouvent repoussées en positon basse, (moitié gauche de la figure 4) si bien que les tétons 32 repoussent vers l'intérieur les ergots respectifs 20 ce qui a pour effet d'une part d'empêcher la solidarisation de la tête 12 avec l'écrou 14 et d'autre part de solidariser l'écrou 14 du corps 1.We first put the corkscrew in the starting position shown in Figure la, in exerting traction on the gripping element 7, this which has the effect of separating the head 12 from the nut 14. Indeed in this position, the spring of compression 35 moves the tubular element 36 away from the base of the body 1 and the slides 34 are pushed back in low position, (left half of figure 4) so that the nipples 32 push inward the lugs 20 which has the effect of preventing the securing of the head 12 with the nut 14 and other part of securing the nut 14 of the body 1.

Ainsi que représenté sur les figures 1b et 6b on introduit ensuite le goulot 3 de la bouteille contenant le bouchon 5 à extraire à l'intérieur de la pince 40 et l'on exerce sur le corps 1 un effort vertical F1, de façon à comprimer au maximum le ressort 35, ce qui a pour effet d'appliquer les parties supérieures biseautées des glissières 34 contre les parties inférieures biseautées des lames élastiques 30, repoussant ainsi les tétons 32 vers l'extérieur ainsi que représenté sur la partie droite de la figure 4. On exerce simultanément, dans le même sens, un effort F'1 de même direction sur l'élément de préhension 7, ce qui a pour effet de déplacer vers le bas la tête 12 tout en imprimant à la vis d'extraction 22 une rotation, en raison de son passage dans l'écrou 14, ce qui lui permet, ainsi que représenté sur les figures 1b et 6b, de pénétrer à l'intérieur du bouchon 5.As shown in FIGS. 1b and 6b, the neck 3 of the bottle containing the stopper 5 to be extracted is then introduced inside the clamp 40 and a vertical force F 1 is exerted on the body 1 , so as to compress the spring 35 as much as possible, which has the effect of applying the bevelled upper parts of the slides 34 against the bevelled lower parts of the elastic blades 30, thus pushing the pins 32 outwards as shown on the right side of the Figure 4. Is exerted simultaneously, in the same direction, a force F ' 1 of the same direction on the gripping member 7, which has the effect of moving down the head 12 while printing the extraction screw 22 a rotation, due to its passage through the nut 14, which allows it, as shown in FIGS. 1b and 6b, to penetrate inside the plug 5.

On notera, qu'une fois la tête 12 arrivée en bout de course, les ergots 20 se présentent en face des trous 19 des languettes 16 qui sont dégagés si bien qu'ils peuvent pénétrer dans ces derniers assurant ainsi la solidarisation de la tête 12 avec l'écrou 14.It will be noted that once the head 12 has reached the end stroke, the lugs 20 are opposite the holes 19 of the tabs 16 which are released so that they can enter the latter thus ensuring the securing of the head 12 with the nut 14.

Au cours de la seconde phase de mise en oeuvre du tire-bouchon suivant l'invention, ou phase d'extraction, représentée sur les figures 1c et 6c, on exerce, sur l'élément de préhension 7, un effort F'2 de direction opposée à l'effort F'1 précédent, ce qui a pour effet d'entraíner vers le haut non seulement la tête 12 mais également l'écrou 14 qui est désormais solidarisé à celle-ci. Au cours de ce mouvement, puisqu'il n'existe pas de déplacement relatif de ces deux parties, la vis d'extraction 22 n'est pas soumise à un mouvement de rotation, et on procède à l'extraction du bouchon 5 du goulot 3.During the second implementation phase of the corkscrew according to the invention, or extraction phase, shown in FIGS. 1c and 6c, a force F ′ 2 is exerted on the gripping element 7. direction opposite to the force F ' 1 above , which has the effect of driving upward not only the head 12 but also the nut 14 which is now secured to it. During this movement, since there is no relative movement of these two parts, the extraction screw 22 is not subjected to a rotational movement, and the stopper 5 is extracted from the neck 3.

Au cours de la troisième phase de mise en oeuvre du tire-bouchon suivant l'invention, ou phase de descente, représentée sur les figures 1d et 6d, on repousse l'élément de préhension 7 dans la direction de la flèche F'1, ce qui a pour effet de ramener la tête 12 et l'écrou 14 en fin de course basse.During the third phase of implementation of the corkscrew according to the invention, or descent phase, shown in FIGS. 1d and 6d, the gripping element 7 is pushed back in the direction of the arrow F ′ 1 , which has the effect of bringing the head 12 and the nut 14 at the end of the lower stroke.

Au cours de la quatrième phase de mise en oeuvre du dispositif suivant l'invention, ou phase d'expulsion, ainsi que représenté sur les figures le et 6e, on exerce sur l'élément de préhension 7 un effort F'2 dirigé vers le haut. Au cours du mouvement qui en résulte, on constate que le ressort 35 repousse vers le bas l'élément tubulaire 36, ce qui a pour effet d'éloigner les parties biseautées des glissières 34 des parties correspondantes des languettes 30, ainsi que représenté sur la partie gauche de la figure 4, si bien que les tétons 32 prennent place dans les trous 19 des languettes 16, ce qui a pour effet d'une part de solidariser l'écrou 14 au corps 1 et de désolidariser la tête 12 de l'écrou 14, puisque les ergots 20 se trouvent repoussés. Au cours de ce mouvement on soulève donc la tête 12, ce qui a pour effet de mettre en rotation la vis d'extraction 22 par rapport au bouchon 5 et donc de la dévisser de ce dernier.During the fourth phase of implementation of the device according to the invention, or expulsion phase, as shown in Figures Le and 6e, exerting on the gripping element 7 a force F ' 2 directed towards the high. During the resulting movement, it can be seen that the spring 35 pushes down the tubular element 36, which has the effect of moving the bevelled parts of the slides 34 away from the corresponding parts of the tongues 30, as shown in FIG. left part of Figure 4, so that the pins 32 take place in the holes 19 of the tabs 16, which has the effect of one hand to secure the nut 14 to the body 1 and to separate the head 12 from the nut 14, since the pins 20 are pushed back. During this movement, the head 12 is therefore raised, which has the effect of rotating the extraction screw 22 relative to the plug 5 and therefore unscrewing it from the latter.

On pourra bien entendu, suivant l'invention remplacer l'élément de préhension constitué d'une poignée simple 7 en prise directe avec la tête 12, par des moyens de duplication d'effort, tels que par exemple un système à leviers du type communément utilisé dans le domaine des tire-bouchons, du type notamment représenté par exemple sur la figure 7.We can of course, according to the invention replace the grip element consisting of a handle simple 7 in direct engagement with the head 12, by means of duplication of effort, such as for example a system with levers of the type commonly used in the field of corkscrews, of the type shown in particular for example in figure 7.

On pourra bien entendu, suivant l'invention réaliser aussi bien les moyens de verrouillage et de déverrouillage que les moyens de déconnexion des moyens de déverrouillage à l'aide de dispositifs différents de ceux décrits en regard des figures 1 à 7.We can of course, according to the invention perform both the locking means and unlocking as the means of disconnecting the means of unlocking using devices other than those described with reference to Figures 1 to 7.

Ainsi, comme représenté sur les figures 8 et 9, on pourra assurer le verrouillage de la tête 12 avec l'écrou 14 par la coopération de deux lamelles élastiques 44 solidaires de la tête 12 et qui se terminent à leurs extrémités antérieures par des crochets 43 qui, en position normale, c'est-à-dire lorsqu'ils ne subissent aucune contrainte, viennent prendre place dans des échancrures 45 prévues à la partie antérieure de l'écrou 14, et assurent ainsi la solidarisation de la tête 12 et de l'écrou 14.Thus, as shown in FIGS. 8 and 9, we can lock head 12 with nut 14 by the cooperation of two elastic strips 44 integral with head 12 and which terminate at their anterior ends by hooks 43 which, in normal position, that is to say when they do not undergo no constraint, come to take place in notches 45 provided in the front part of the nut 14, and thus ensure the joining of the head 12 and of the nut 14.

Le dispositif comporte des moyens de déverrouillage qui sont constitués par des éléments longitudinaux 47 qui sont montés mobiles suivant l'axe longitudinal yy' du tire-bouchon et qui sont sollicités par des moyens élastiques 49 dans le sens de la flèche F3, de façon à venir en appui sur la base des crochets 43. Les moyens élastiques 49 sont tels qu'ils sont en mesure de déformer les languettes 44 vers l'extérieur, de façon à extraire les crochets 43 des échancrures 45, libérant ainsi la tête 12 de l'écrou 14.The device comprises unlocking means which are constituted by longitudinal elements 47 which are mounted movable along the longitudinal axis yy 'of the corkscrew and which are urged by elastic means 49 in the direction of the arrow F 3 , so coming to bear on the base of the hooks 43. The elastic means 49 are such that they are able to deform the tongues 44 outwards, so as to extract the hooks 43 from the notches 45, thus freeing the head 12 from the nut 14.

Le dispositif comprend également des moyens de déconnexion des éléments de déverrouillage 47, représentés de façon schématique par un élément de traction transversal 50 et qui permet, en faisant pivoter les éléments 47 de les désengager d'avec la base des crochets 43. Les crochets 43 ainsi libérés prennent de nouveau place, ainsi que représenté sur la figure 9, dans les échancrures 45 assurant ainsi la solidarisation de la tête 12 et de l'écrou 14.The device also includes means for disconnection of the unlocking elements 47, shown schematically by a traction element transverse 50 and which allows, by rotating the elements 47 to disengage them from the base of the hooks 43. The hooks 43 thus released take again place, as shown in Figure 9, in the notches 45 thus ensuring the joining of the head 12 and nut 14.

On peut bien entendu, dans le cadre de l'invention mettre en oeuvre tout autre moyen permettant d'assurer la déconnexion des moyens de déverrouillage de façon à assurer la solidarisation de la tête 12 et de l'écrou 14.One can of course, within the framework of the invention implement any other means to ensure the disconnection of the unlocking means so as to securing the head 12 and the nut 14.

On a ainsi représenté sur les figures 10 et suivantes une telle variante de mise en oeuvre de l'invention.There is thus shown in FIGS. 10 and following such an implementation variant of the invention.

Ce tire-bouchon est ainsi essentiellement constitué d'un corps tubulaire formé de deux coquilles 2' identiques, qui sont liées en translation par des tétons 6' qui prennent place dans des trous correspondants de ces coquilles. Les deux coquilles 2' une fois assemblées sont enfilées dans un fourreau 9' en trois parties 9'a, 9'b et 9'c, qui assure le maintien de l'ensemble.This corkscrew is thus essentially consisting of a tubular body formed by two shells 2 ' identical, which are linked in translation by nipples 6 'which take place in corresponding holes of these shells. The two 2 'shells, once assembled, are threaded in a sheath 9 'in three parts 9'a, 9'b and 9'c, which maintains the assembly.

Les deux coquilles 2' sont creusées d'une rainure centrale et longitudinale 8' de faible largeur qui se termine à sa base par une rainure transversale 8'a. La rainure longitudinale 8' est destinée à assurer le guidage à l'intérieur des coquilles d'un tiroir mobile 10'.The two shells 2 'are hollowed out with a groove central and longitudinal 8 'narrow width which ends at its base with a transverse groove 8'a. The longitudinal groove 8 'is intended to provide guidance inside the shells of a movable drawer 10 '.

Ce tiroir 10' est essentiellement constitué de trois éléments de forme globale cylindrique, à savoir une tête supérieure 12', une douille médiane 13 et un écrou inférieur 14'.This drawer 10 'is essentially made up of three elements of overall cylindrical shape, namely a upper head 12 ', a central sleeve 13 and a nut lower 14 '.

La tête 12' est formée d'une partie supérieure cylindrique de même diamètre que celui de l'intérieur des coquilles 2' sur laquelle sont disposés deux tétons de guidage radiaux 60 diamétralement opposés, destinés à se déplacer respectivement dans les rainures longitudinales 8' des coquilles 2'. Cette partie se prolonge vers le bas par une portion cylindrique 62 de plus faible diamètre, se terminant par un épaulement séparé en quatre butées radiales 64 diamétralement opposées par quatre rainures longitudinales 63. Ainsi que représenté sur la figure 13, la portion 62 est creusée d'une cavité cylindrique axiale dans laquelle est enchâssé un roulement à billes 66 qui assure le maintien à rotation d'un axe 65 dont est solidaire la mèche 22' du tire-bouchon. The head 12 'is formed by an upper part cylindrical with the same diameter as the inside of the 2 'shells on which are arranged two nipples of diametrically opposed radial guides 60, intended to be move respectively in the longitudinal grooves 8 'of the shells 2'. This part extends downwards by a cylindrical portion 62 of smaller diameter, is ending with a shoulder separated into four stops radial 64 diametrically opposed by four grooves longitudinal 63. As shown in FIG. 13, the portion 62 is hollowed out with an axial cylindrical cavity in which is embedded a ball bearing 66 which maintains the rotation of an axis 65 which is secured to the wick 22 'of the corkscrew.

La douille médiane 13 est constituée d'un élément cylindrique tubulaire qui se termine à sa partie inférieure par un bossage circulaire 67. Ce dernier est pourvu de deux tétons radiaux 68 diamétralement opposés destinés à se déplacer dans les rainures respectives 8' et 8'a des coquilles 2'. La partie supérieure de la douille 13 est pourvue de quatre butées internes radiales 69 disposées à 90 degrés dont la largeur est légèrement inférieure à celle des rainures longitudinales 63. Ces butées sont disposées de telle façon que leurs deux axes diamétraux uu' forment un angle α, voisin de 45°, avec l'axe diamétral des tétons 68, ainsi que représenté sur la figure 12. La partie supérieure de la douille 13 est pourvue de quatre rainures longitudinales 72 qui s'étendent sensiblement sur la moitié de la hauteur de la douille 13 et qui sont destinées à conférer à cette partie supérieure de la douille, et notamment à celle comportant les butées 69, une certaine élasticité. Cette élasticité est destinée à permettre aux butées 64 disposées à la base de la tête 12' de pénétrer à l'intérieur de la douille 13 en repoussant les butées 69 de façon à assurer la solidarisation en translation de la tête 12' et de la douille 13 tout en permettant une liberté en rotation de ces deux pièces, ainsi qu'il sera exposé ci-après.The middle sleeve 13 consists of an element cylindrical tubular which ends at its part lower by a circular boss 67. The latter is provided with two diametrically opposed radial nipples 68 intended to move in the respective grooves 8 'and 8 'has 2' shells. The upper part of the socket 13 is provided with four internal radial stops 69 arranged at 90 degrees whose width is slightly lower than that of the longitudinal grooves 63. These stops are arranged so that their two axes diametral uu 'form an angle α, close to 45 °, with the diametrical axis of the nipples 68, as shown in the figure 12. The upper part of the socket 13 is provided with four longitudinal grooves 72 which extend substantially over half the height of the socket 13 and which are intended to give this part upper part of the socket, and in particular to that comprising the stops 69, a certain elasticity. This elasticity is intended to allow the stops 64 arranged at the base from the head 12 'to penetrate inside the socket 13 pushing back the stops 69 so as to ensure the securing in translation of the head 12 ′ and of the socket 13 while allowing freedom in rotation of these two parts, as will be explained below.

L'écrou 14' comprend une partie supérieure cylindrique 74, une embase 76 de plus grand diamètre, et deux tétons 78 diamétralement opposés, destinés à se déplacer, en cours de fonctionnement du tire-bouchon, dans la rainure 8'. L'intérieur de l'écrou 14', qui n'est pas représenté ni décrit ci-après, est identique à l'écrou utilisé dans le mode de mise en oeuvre précédent et est destiné à recevoir la mèche 22' et à assurer la rotation de celle-ci lorsqu'un déplacement longitudinal relatif se produit entre la tête 12' et l'écrou 14'. L'écrou 14' est destiné à prendre place dans la base de la douille 13. A cet effet celle-ci comporte une double rainure à savoir une rainure transversale 80 et une rainure longitudinale 82 destinée à permettre l'accès du téton 78 à la rainure transversale 80. Des moyens élastiques constitués d'un ressort de torsion 79, ont pour effet, ainsi que représenté sur la figure 10, d'écarter le téton 68 du téton 78. C'est pourquoi dès mise en place de l'écrou 14' dans la douille 13 les tétons auront le positionnement angulaire relatif représenté sur la figure 10.The nut 14 'includes an upper part cylindrical 74, a base 76 of larger diameter, and two diametrically opposed nipples 78, intended to be move, during the operation of the corkscrew, in groove 8 '. The inside of the nut 14 ', which is not shown or described below, is identical to the nut used in the previous embodiment and is intended to receive the wick 22 'and to ensure the rotation of this when a relative longitudinal displacement occurs product between head 12 'and nut 14'. The 14 'nut is intended to take place in the base of the socket 13. A this effect it has a double groove namely a transverse groove 80 and a longitudinal groove 82 intended to allow access from the stud 78 to the groove transverse 80. Elastic means consisting of a torsion spring 79, as well as shown in Figure 10, to separate the stud 68 from the nipple 78. This is why as soon as the nut 14 'is put in place in the socket 13 the nipples will have the positioning relative angular shown in figure 10.

Ainsi que dans le mode de mise en oeuvre précédent, le présent dispositif comporte un organe de commande 34' permettant d'inhiber les moyens de déverrouillage existant entre la tête 12' et l'écrou 14'. Cet organe de commande 34' est constitué d'une rondelle 84 qui est pourvue de pattes longitudinales 86 qui s'étendent vers le haut et qui se terminent à leur partie supérieure par un pan incliné 88 d'environ 45° par rapport à l'axe longitudinal yy' du tire-bouchon. Entre les coquilles 2' et l'organe de commande 34', est disposé un ressort de compression 90 qui, en position de repos, éloigne celui-ci des tétons 68. Des moyens de guidage de cet organe de commande 34' sont prévus, qui lui permettent lorsqu'on le déplace vers le haut, à l'encontre de la force du ressort 90, de venir en contact, par ses pans inclinés 88, avec les tétons 68 et de les repousser angulairement pour les amener suivant l'axe yy' du tire-bouchon.As well as in the mode of implementation previous, this device includes a command 34 'to inhibit the means of unlocking existing between the head 12 'and the nut 14'. This control member 34 'consists of a washer 84 which is provided with longitudinal legs 86 which extend upwards and ending at the top by an inclined face 88 of about 45 ° relative to the axis longitudinal yy 'of the corkscrew. Between the shells 2 ' and the control member 34 ', is arranged a spring of compression 90 which, in the rest position, moves it away nipples 68. Means for guiding this member of 34 'controls are provided, which allow it when moves up, against the force of the spring 90, to come into contact, by its inclined faces 88, with the nipples 68 and push them back angularly for them bring along the axis yy 'of the corkscrew.

Comme dans le mode de mise en oeuvre précédent, la base du présent dispositif comporte des moyens de guidage 40' destinés à assurer le centrage de l'ensemble sur le goulot 3 d'une bouteille.As in the previous embodiment, the base of the present device includes guide means 40 'intended to ensure the centering of the assembly on the neck 3 of a bottle.

Dans ces conditions, le fonctionnement du présent tire-bouchon s'établit ainsi que décrit ci-après.Under these conditions, the functioning of the present corkscrew is established as described below.

En position de repos, c'est-à-dire lorsqu'aucune contrainte ne s'exerce sur le tire-bouchon, la tête 12' est en place dans la douille 13 et l'ensemble du tiroir 10' se trouve en position basse, si bien que la mèche 22' fait saillie sous le tiroir 10'. Les tétons 78 de l'écrou 14' sont en place dans leurs rainures verticales respectives 8'. Le ressort de torsion 79 exerçant un couple de torsion relatif entre l'écrou 14' et la douille 13 tendant à éloigner les tétons 78 et 68, ces derniers se trouvent respectivement appliqués dans le fond des rainures transversales 8'a. Dans ces conditions, ainsi qu'on peut le voir sur la figure 10, les butées 69 se trouvent superposées, sur le même axe longitudinal, aux rainures 63, si bien qu'une traction exercée vers le haut par l'élément de préhension 7' sur la tête 12' aura pour effet de désolidariser celle-ci de la douille 13 et ainsi de remonter cette dernière en partie supérieure du tire-bouchon. Une telle action correspond à la phase d'actionnement représentée sur la figure schématique 1a.In the rest position, i.e. when no stress is exerted on the corkscrew, the 12 'head is in place in the socket 13 and the entire drawer 10 'is in the low position, so that the drill bit 22' protrudes under the drawer 10 '. Nipples 78 of the nut 14 'are in place in their vertical grooves respective 8 '. The torsion spring 79 exerting a relative torque between the 14 'nut and the socket 13 tending to separate the nipples 78 and 68, the latter are respectively found in the background of transverse grooves 8'a. Under these conditions, as well as can be seen in Figure 10, the stops 69 are are superimposed, on the same longitudinal axis, on the grooves 63, so that an upward pull by the gripping element 7 'on the head 12' will have for effect of detaching it from the socket 13 and thus to reassemble the latter in the upper part of the corkscrew. Such an action corresponds to the phase actuation shown in schematic figure 1a.

On applique ensuite la base du tire-bouchon sur le goulot 3 de la bouteille, si bien que l'organe de commande 34' se déplace vers le haut, à l'encontre de la force de compression opposée par le ressort 90, et que ses pans inclinés 88 repoussent angulairement le téton 68 vers l'axe longitudinal yy' du tire-bouchon, ce qui a pour effet de faire tourner la douille 13 et d'amener ses butées 69 face aux butées 64 de la tête 12'. On repousse alors vers le bas la tête 12' avec une force F'1, ainsi que représenté sur la figure 1b, et, au cours de ce déplacement vers le bas de la tête 12', la mèche 22' se visse dans l'écrou 14 ce qui imprime à celle-ci un mouvement de rotation qui a pour effet de l'enfoncer dans le bouchon 5. En fin de course vers le bas, les butées 64 de la tête 12' et les butées 69 de la douille 13 viennent en contact les unes des autres et si l'on continue d'exercer un effort vers le bas, la douille se déforme en raison de l'élasticité qui lui est conférée par les rainures verticales 72 et, on provoque un encliquetage, provoquant un claquement reconnaissable indiquant à l'utilisateur que la course vers le bas est terminée.Then apply the base of the corkscrew to the neck 3 of the bottle, so that the control member 34 'moves upwards, against the force of compression opposed by the spring 90, and that its sides inclined 88 angularly push the nipple 68 towards the longitudinal axis yy 'of the corkscrew, which has effect of rotating the socket 13 and bringing its stops 69 facing the stops 64 of the head 12 '. We push back then down the head 12 'with a force F'1, as well as shown in Figure 1b, and, during this downward movement of the head 12 ', the drill bit 22' is screws into nut 14 which gives it a rotational movement which has the effect of pushing it into the plug 5. At the bottom of the stroke, the stops 64 of the head 12 'and the stops 69 of the sleeve 13 come in contact with each other and if we continue to exert a downward force, the sleeve deforms into because of the elasticity conferred on it by vertical grooves 72 and, a snap is caused, causing a recognizable click indicating to user that the race to the bottom is over.

Dans cette position, l'élément 34' continue d'exercer sur le téton 68 un effort tendant à le maintenir suivant l'axe yy' du tire-bouchon, si bien que les butées 64 de la tête et les butées 64 de la douille restent en prise, de sorte que la tête 12' et la douille 13 restent solidaires en translation. In this position, the element 34 'continues to exert on the nipple 68 an effort tending to maintain it along the yy 'axis of the corkscrew, so that the stops 64 of the head and the stops 64 of the socket remain in taken, so that the head 12 'and the socket 13 remain united in translation.

On exerce ensuite, ainsi que représenté sur la figure schématique 1c, un effort vertical ascendant F'2 sur la tête 12' qui, en raison de la solidarisation de la tête 12' et de la douille 13, a pour effet de soulever l'ensemble du tiroir 10 si bien que la mèche 22' reste immobile et que, dans ces conditions, on extrait le bouchon 5 du goulot de la bouteille 3.We then exercise, as shown in the schematic figure 1c, an upward vertical force F'2 on the head 12 'which, due to the connection of the head 12 'and socket 13, has the effect of lifting the entire drawer 10 so that the wick 22 'remains motionless and that, under these conditions, the cap 5 of the neck of the bottle 3.

Une fois le bouchon 5 extrait, on enlève le tire-bouchon du goulot de la bouteille, si bien que, dans ces conditions, l'organe de commande 34' reprend sa position inférieure où il est inopérant. On exerce alors sur la tête 12' un effort vertical du haut vers le bas, ainsi que représenté sur la figure 1d, ce qui a pour effet de descendre l'ensemble du tiroir 10 et, lorsque celui-ci arrive à la partie inférieure, l'élément 34' étant inopérant, le ressort de torsion 79 sollicite alors les tétons 68 pour les amener de nouveau au fond des rainures transversales respectives 8'a, ce qui provoque une rotation d'environ 45 degrés de la douille 13. Dès lors, celle-ci reprend sa position angulaire représentée sur la figure 10 et, dans ces conditions, les butées 69 se trouvent face aux rainures 63, si bien que toute action vers le haut exercée sur la tête 12' a pour effet de désolidariser celle-ci de la douille 13. Au cours de ce mouvement, ainsi que représenté sur la figure 1e, le passage de la mèche 22' dans l'écrou 14' a pour effet d'appliquer un mouvement de rotation à celle-ci provoquant sa désolidarisation du bouchon 5. Il suffit alors de ramener vers le bas la tête 12' pour que le tire-bouchon se trouve de nouveau en position de départ.Once the cork 5 has been removed, the corkscrew is removed from the neck of the bottle, so that in these conditions, the control member 34 'returns to its position lower where it is inoperative. We then exercise on the head 12 'a vertical effort from top to bottom, as well as shown in Figure 1d, which has the effect of lower the entire drawer 10 and, when it arrives at the bottom, element 34 'being inoperative, the torsion spring 79 then urges the nipples 68 to bring them back to the bottom of the grooves respective transverse 8'a, which causes a rotation of the socket 13 approximately 45 degrees. it returns to its angular position shown on the Figure 10 and, under these conditions, the stops 69 are face grooves 63, so that any action upwards exerted on the head 12 ′ has the effect of detach it from the socket 13. During this movement, as shown in Figure 1e, the passage of the drill bit 22 'in the nut 14' has the effect to apply a rotational movement to it causing its separation from the plug 5. It then suffices to bring the 12 'head down so that the corkscrew is again in the starting position.

Un tel mode de mise en oeuvre est partiellement intéressant en ce qu'il permet une construction avec des pièces simples obtenues en quasi totalité par moulage, ce qui les rend particulièrement intéressante au niveau du prix de revient.Such an implementation is partially interesting in that it allows a construction with simple parts obtained almost entirely by molding, this which makes them particularly interesting in terms of cost price.
