Description

La présente invention concerne les tirebouchons équipés de moyens permettant de réduire dans d'importantes proportions l'effort et le temps d'extraction des bouchons de bouteilles ou récipients analogues.The present invention relates to corkscrews equipped with means making it possible to reduce in considerable proportions the effort and the time of extraction of the corks from bottles or similar containers.

On connaît déjà un tire-bouchon à démultiplication par palan décrit dans le brevet français N° 1.589.350 et dans le brevet allemand (RFA) N° 204.020. Le mode de réalisation de ces tirebouchons est compliqué et onéreux, de plus, ils engendrent des frottements qui font perdre une partie du gain de la démultiplication de l'effort d'extraction. De plus, il est très difficile d'extraire les bouchons qui ont été tirés en biais et qui sont coîncés dans le corps tubulaire.A corkscrew with gear reduction by hoist is already known, described in French patent No. 1,589,350 and in German patent (FRG) No. 204,020. The embodiment of these corkscrews is complicated and expensive, moreover, they generate friction which makes lose part of the gain of the reduction of the extraction effort. In addition, it is very difficult to extract the plugs which have been pulled at an angle and which are caught in the tubular body.

L'objet de ce tire-bouchon est de pallier ces divers inconvénients tout en offrant un emploi très simple et très rapide.The object of this corkscrew is to overcome these various drawbacks while offering a very simple and very fast use.

L'invention qui est basée sur l'art connu par le brevet français N° 1.589.350 tel qu'analysé dans le préambule des revendications 1 et 3, est caractérisée par l'objet des revendications et résoud le problème consistant à créer un tirebouchon à démultiplication par palan très simple à fabriquer et à monter, conçu selon deux versions de simplicité croissante.The invention which is based on the art known by French patent N ° 1,589,350 as analyzed in the preamble of claims 1 and 3, is characterized by the subject of the claims and solves the problem of creating a corkscrew with gear reduction by hoist very simple to manufacture and to assemble, designed according to two versions of increasing simplicity.

La première version selon l'invention simplifie le tire-bouchon décrit dans le brevet français cité ci-dessus, et notamment la conception de la poignée de manoeuvre et le montage. Le moyen de rappel élastique est une tige centrale de guidage traversant le moufle supérieur encastrée dans le moufle inférieur, sur laquelle est glissé un ressort de rappel en appui sur chacun des moufles. Le moufle inférieur se déplace d'une course égale à celle de l'extraction cependant que le moufle supérieur est fixe. La poignée de manoeuvre solidaire du tube télescopique extérieur se déplace avec lui en entraînant la courroie de traction du moufle inférieur.The first version according to the invention simplifies the corkscrew described in the French patent cited above, and in particular the design of the operating handle and the mounting. The elastic return means is a central guide rod passing through the upper block inserted in the lower block, on which is slid a return spring resting on each of the blocks. The lower block moves a stroke equal to that of the extraction while the upper block is fixed. The operating handle integral with the outer telescopic tube moves with it, driving the traction belt of the lower block.

La deuxième version est encore plus simple que la précédente en ce que les tubes télescopiques sont remplacés par un corps tubulaire dans le fond duquel est fixé le moufle supérieur qui reste immobile. Le moufle inférieur se déplace de la course d'extraction pour aller, en fin de course d'extraction, en butée contre le moufle supérieur sous l'action de la traction sur un cordonnet souple qui s'enroule sur les deux moufles et sort hors du corps tubulaire par un trou de son extrémité supérieure. Les moufles et le corps tubulaire sont réalisés en matière plastique moulée, ce qui supprime nombre d'usinages et réduit le temps de montage.The second version is even simpler than the previous one in that the telescopic tubes are replaced by a tubular body in the bottom of which is fixed the upper block which remains stationary. The lower muffle moves from the extraction stroke to go, at the end of the extraction stroke, in abutment against the upper muffle under the action of traction on a flexible cord which is wound on the two mittens and comes out of the tubular body through a hole in its upper end. The mittens and the tubular body are made of molded plastic, which eliminates many machining operations and reduces assembly time.

Les avantages obtenus grâce à cette invention consistent essentiellement en ceci que la fabrication et le montage sont grandement simplifiés, que les frottements sont très réduits et que, pour une même démultiplication, l'effort de traction est moindre, de plus, la vrille se trouve automatiquement centrée sur le bouchon à extraire. Il est facile de retirer du corps les bouchons qui ont été tirés en biais et qui sont coincés.The advantages obtained thanks to this invention consist essentially in that the manufacturing and the assembly are greatly simplified, that the friction is very reduced and that, for the same reduction, the tensile force is less, moreover, the spin is found automatically centered on the cap to be extracted. It is easy to remove plugs that have been pulled at an angle and are stuck in the body.

Le premier mode de réalisation représenté sur les figures 1 et 2 comporte un tube principal 1 évasé à sa base pour servir de guide et d'appui sur le goulot des bouteilles à déboucher. Ce tube est épaulé en 2 de façon à constituer une butée de fin de course d'extraction. La seconde partie du tube possède également un épaulement 3 qui sert d'appui interne au corps du moufle supérieur 4.The first embodiment shown in Figures 1 and 2 comprises a main tube 1 flared at its base to serve as a guide and support on the neck of the bottles to be opened. This tube is shouldered in 2 so as to constitute an extraction end stop. The second part of the tube also has a shoulder 3 which serves as an internal support for the body of the upper block 4.

Trois tubes rallonges télescopiques 23, 24, 25, glissent les uns sur les autres pour conserver la poignée 18 dans l'axe du tube principal 1 pendant l'extraction du bouchon. Ils sont évasés à leur extrémité supérieure et rétrécis à la base pour éviter leur déboîtement en cours de coulissement. Pour permettre le vissage de la vrille 26 dans les bouchons au moyen de la poignée 18, les différents tubes ont reçu quatre emboutissages longitunaux 27, 28, 29, 30, évitant le vrillage des tubes (Fig. 3). La poignée 18 est emmanchée dans l'extrémité libre du tube extérieur 25, ses deux tiges sont engagées dans les rainures opposées 31,32, du tube 25 pour assurer l'entraînement en rotation. La poignée est soit collée sur le tube 25, ou bien le tube 25 est serti sur la poignée pour pouvoir tirer dessus sans risquer de la déboîter. Lorsque l'on tire sur la poignée 18, on exerce une traction sur la courroie, les tubes glissent les uns sur les autres, le tire-bouchon s'allonge, la rondelle porte-vrille 6 s'enfonce dans le corps 1 jusqu'à venir en butée sur l'épaulement 2 en fin d'extraction du bouchon. On relâche alors la poignée et les ressorts de rappel ramènent le moufle inférieur en position basse pour une nouvelle extraction. Le tube rallonge extérieur 25, sous l'action du ressort 11, se trouve en butée sur l'épaulement du tube 1.Three telescopic extension tubes 23, 24, 25, slide over each other to keep the handle 18 in the axis of the main tube 1 during the extraction of the plug. They are flared at their upper end and narrowed at the base to avoid their dislocation during sliding. To allow the screw 26 to be screwed into the stoppers by means of the handle 18, the various tubes have received four longitudinal stampings 27, 28, 29, 30, preventing the tubes from twisting (Fig. 3). The handle 18 is fitted into the free end of the outer tube 25, its two rods are engaged in the opposite grooves 31, 32 of the tube 25 to ensure the drive in rotation. The handle is either glued to the tube 25, or the tube 25 is crimped onto the handle so that it can be pulled without risking to dislodge it. When the handle 18 is pulled, traction is exerted on the belt, the tubes slide one on the other, the corkscrew lengthens, the gimlet washer 6 sinks into the body 1 until coming into abutment on the shoulder 2 at the end of extraction of the plug. The handle is then released and the return springs bring the lower block back to the low position for further extraction. The outer extension tube 25, under the action of the spring 11, is in abutment on the shoulder of the tube 1.

Un moufle inférieur 5 en tôle pliée est solidarisé à la plaque porte-vrille 6 par deux rivets 7. Le moufle 5 forme une chape sur laquelle sont montées, de chaque côté en porte-à-faux, des poulies à gorge identiques 8, 9. Une tige centrale de guidage 10 porte un ressort de rappel 11 destiné à ramener la plaque porte-vrille 6 en position repos. La tige de guidage 10 traverse le moufle supérieur 4, identique au moufle inférieur, et est engagée dans un trou central d'une rondelle 12 de fixation du moufle supérieur sur l'extrémité 3 du tube 1 par l'intermédiaire de rivets aveugles 13. Les poulies 8, 9, sont montées tournant librement sur les axes 14, 15, sertis sur la chape. Un câble souple 16 qui peut être en acier toronné, ou en matière plastique dû-genre fil à pêche ou corde tressée présentant une grande résistance à l'allongement, est engagé, par sa partie inférieure, dans une rondelle 6 arrêtée par un renflement 17 obtenu par surmoulage ou par une agrafe sertie ou par tout autre moyen connu. Il s'enroule ensuite sur la poulie 8 du moufle supérieur, revient sur la poulie 8 du moufle inférieur puis remonte sur la poulie 9 du moufle supérieur, descend sur la poulie 9 du moufle inférieur et remonte s'accrocher sur une poignée de manoeuvre 18 réalisée par moulage. L'accrochage s'effectue sur un axe 19 engagé dans une rainure 20 qui peut venir de moulage dans la poignée 18. La tige de guidage 10 peut être immobilisée au niveau de l'encastrement inférieur. Pour éviter que le câble quitte les poulies au moment du retour élastique à la position de repos, on a prévu des ergots 21, 22, au droit de chaque poulie.A lower block 5 made of folded sheet metal is secured to the swivel plate 6 by two rivets 7. The block 5 forms a yoke on which are mounted, on each side in cantilever, pulleys with identical grooves 8, 9 A central guide rod 10 carries a return spring 11 intended to bring the gimbal plate 6 back into the rest position. The guide rod 10 passes through the upper block 4, identical to the lower block, and is engaged in a central hole in a washer 12 for fixing the upper block on the end 3 of the tube 1 by means of blind rivets 13. The pulleys 8, 9 are mounted freely rotating on the axes 14, 15, crimped on the yoke. A flexible cable 16 which may be made of stranded steel, or of plastics material such as fishing line or braided rope having great resistance to elongation, is engaged, by its lower part, in a washer 6 stopped by a bulge 17 obtained by overmolding or by a crimped staple or by any other known means. It is then wound on the pulley 8 of the upper block, returns to the pulley 8 of the lower block and then rises on the pulley 9 of the upper block, descends on the pulley 9 of the lower block and goes up to hang on an operating handle 18 produced by molding. The attachment is effected on an axis 19 engaged in a groove 20 which may come from molding in the handle 18. The guide rod 10 can be immobilized at the lower recess. To prevent the cable from leaving the pulleys when elastic return to the rest position, lugs 21, 22 have been provided at the right of each pulley.

La figure 5 montre la forme de la rondelle 12 de fixation du palier supérieur sur l'épaulement du tube 1. La fente 35 permet le passage du câble vers son point d'accrochage sur l'axe 19. Les trous 36 reçoivent les rivets aveugles 13 assurant l'immobilisation sur le tube 1.Figure 5 shows the shape of the washer 12 for fixing the upper bearing on the shoulder of the tube 1. The slot 35 allows the passage of the cable to its point of attachment on the axis 19. The holes 36 receive the blind rivets 13 ensuring immobilization on the tube 1.

La figure 4 est une coupe suivant la flèche 37 (figure 1) montrant la disposition du moufle supérieur dans la partie rétrécie du tube 1, ainsi que l'emplacement des poulies 8, 9.FIG. 4 is a section along arrow 37 (FIG. 1) showing the arrangement of the upper block in the narrowed part of the tube 1, as well as the location of the pulleys 8, 9.

Telle qu'elle est représentée en coupe sur la figure 6, la deuxième version de tire-bouchon selon l'invention comporte un corps tubulaire 40 pouvant être muni, à l'extérieur, de moyens, pans polygonaux, rainures longitudinales ou autres, pour assurer une bonne tenue manuelle du tube pour le vissage car il n'est pas nécessaire d'utiliser de poignée comme dans les versions précédentes puisqu'il n'y a pas à tirer sur un tube télescopique. La partie inférieure 41 est évasée pour le centrage sur la partie supérieure du goulot des bouteilles en fin de vissage.As shown in section in Figure 6, the second version of corkscrew according to the invention comprises a tubular body 40 which can be provided, outside, with means, polygonal sides, longitudinal grooves or the like, for ensure good manual holding of the tube for screwing because it is not necessary to use a handle as in previous versions since there is no pull on a telescopic tube. The lower part 41 is flared for centering on the upper part of the neck of the bottles at the end of screwing.

Les tubes télescopiques ont été supprimés, le frottement interne est donc très réduit. Le mouflage est également simplifié, il est constitué par le moufle supérieur 42 et le moufle inférieur 43 tous les deux obtenus en matière plastique moulée par injection. Le corps tubulaire peut être moulé en métal léger ou également en matière plastique. Tous les usinages sont supprimés sauf la plaque porte-vrille 44 et les axes de poulies.The telescopic tubes have been eliminated, the internal friction is therefore very reduced. The hauling is also simplified, it consists of the upper block 42 and the lower block 43 both obtained from injection molded plastic. The tubular body can be molded from light metal or also from plastic. All machining is eliminated except the gimbal plate 44 and the pulley axes.

Le corps tubulaire 40 comporte quatre rainures 45 (fig.8) servant de guidage et d'antirotation au moufle inférieur 43 ainsi qu'à la plaque 44 portant la vrille 46 sertie ou soudée. Le moufle inférieur 43 est assujetti à la plaque porte-vrille par les sertissages 47, de l'étrier 48 les sertissages sont exécutés en cours de montage des moufles.The tubular body 40 has four grooves 45 (fig.8) serving as guidance and anti-rotation to the lower block 43 as well as to the plate 44 carrying the swirler 46 crimped or welded. The lower block 43 is fixed to the tendril plate by the crimps 47, from the stirrup 48 the crimps are executed during assembly of the mittens.

L'étrier 48 sert de guidage aux deux ressorts de rappel 49, 50. Il traverse le moufle supérieur par les trous 51, 52, et le moufle inférieur par les trous 53, 54, ces trous sont lamés sur la plus grande partie de leur longueur pour assurer l'appui et le passage des ressorts de rappel 49, 50.The stirrup 48 serves as a guide for the two return springs 49, 50. It passes through the upper block through the holes 51, 52, and the lower block through the holes 53, 54, these holes are cut over most of their length to ensure support and passage of return springs 49, 50.

En variante, on peut augmenter le pas entre les tiges de l'étrier de façon à ne laisser subsister que l'embase et une chape pour tenir les axes de poulies 55, 56 et 57, 58, des moufles ainsi que l'axe 59 destiné à l'accrochage du cordonnet 60 sur le moufle inférieur.As a variant, the pitch between the stirrup rods can be increased so as to leave only the base and a yoke to hold the axes of pulleys 55, 56 and 57, 58, the mittens as well as the axis 59 intended for the attachment of the cord 60 to the lower block.

Les axes 59 peuvent être libres dans leur logement car ils sont maintenus en place par les ressorts 49, 50. On peut également les laisser libres dans leur logement, mais les emmancher légèrement dur dans les poulies ou l'inverse.The pins 59 can be free in their housing because they are held in place by the springs 49, 50. They can also be left free in their housing, but fitting them slightly hard in the pulleys or vice versa.

Les sertissages 61 sont effectués après mise en place de l'étrier dans le moufle 42 et des ressorts 49, 50. On place ensuite le moufle 43 et la plaque 44 et l'on effectue le sertissage 47. L'ensemble du palan est alors engagé dans le corps 40. Le moufle supérieur 42 est amené en buté au fond du corps tubulaire 40 et est immobilisé par une goupille 62 traversant en travers le corps 40 et le moufle 42. On pourrait également coller le moufle.The crimps 61 are made after the stirrup has been placed in the muffle 42 and the springs 49, 50. The muffle 43 and the plate 44 are then placed and the crimping performed 47. The entire hoist is then engaged in the body 40. The upper block 42 is brought into abutment at the bottom of the tubular body 40 and is immobilized by a pin 62 passing through the body 40 and the block 42. The block could also be glued.

La figure 7 montre en coupe suivant B de la figure 6 la disposition du palan. Le cordonnet 60 accroché sur l'axe 59, passe successivement sur les poulies 58, 56, 57, 55, et sort du corps tubulaire 40 par la rainure 63 (fig. 11) et par le trou 64 (fig. 8) pour pendre le long du corps 40 sous le poids de l'anneau 65 sur lequel il est fixé.Figure 7 shows in section along B of Figure 6 the arrangement of the hoist. The cord 60 hooked on the axis 59, passes successively on the pulleys 58, 56, 57, 55, and leaves the tubular body 40 through the groove 63 (fig. 11) and through the hole 64 (fig. 8) to hang along the body 40 under the weight of the ring 65 on which it is fixed.

Sur la figure 7 on a montré en variante de la figure 6, une douille 66 en matière plastique moulée, coulissant sur l'extrémité inférieure du corps 40 et susceptible de se clipser élastiquement dans les gorges 67, 68, du corps 40. Cette douille a pour fonction de centrer le tire- bouchon sur la bouteille. Avant de placer le tire- bouchon, on repousse la douille 66 vers le bas jusqu'à ce qu'elle se clipse élastiquement dans la gorge 68 du corps. On pose ensuite la partie évasée de la douille sur le dessus du goulot de la bouteille, puis on pousse alors l'extrémité supérieure du corps tubulaire, la douille se déclipse et remonte légèrement jusqu'à ce que la pointe de la vrille touche le bouchon sur lequel elle est alors centrée. Il ne reste plus qu'à visser la vrille jusqu'à ce que l'extrémité inférieure du corps tubulaire s'appuie sur le dessus du goulot de la bouteille, la douille 66 est alors entièrement remontée sur le corps 40 et peut se clipser dans la gorge 67. Il ne reste plus qu'à tirer sur l'anneau 65 pour extraire le bouchon. Le moufle inférieur monte dans le corps 40 jusqu,à venir en butée sur le moufle supérieur42 en fin d'extraction cependant que l'étrier 48 est sorti du corps 40 par le trou 64 (représenté en traits pointillés fins sur la figure 6). Lorsque l'on relâche le cordonnet 60, les ressorts de rappel 49, 50, ramènent le moufle inférieur 43 en position de repos vers le bas jusqu'à ce que la partie supérieure de l'étrier repose en butée sur le dessus du moufle 42.In FIG. 7, a variant of FIG. 6 has been shown, a sleeve 66 of molded plastic material, sliding on the lower end of the body 40 and capable of being clipped elastically into the grooves 67, 68, of the body 40. This sleeve has the function of centering the corkscrew on the bottle. Before placing the corkscrew, the sleeve 66 is pushed down until it snaps elastically into the groove 68 of the body. Then put the flared part of the socket on top of the neck of the bottle, then push the upper end of the tubular body, the socket unclips and rises slightly until the tip of the spin touches the cap on which it is then centered. It only remains to screw the spin until the lower end of the tubular body rests on the top of the neck of the bottle, the sleeve 66 is then completely reassembled on the body 40 and can be clipped into throat 67. All that remains is to pull the ring 65 to extract the plug. The lower block goes up in the body 40 until it comes into abutment on the upper block 42 at the end of extraction, while the stirrup 48 has come out of the body 40 through the hole 64 (shown in fine dotted lines in FIG. 6). When the cord 60 is released, the return springs 49, 50 bring the lower block 43 back into the down position until the upper part of the stirrup abuts on top of the block 42 .

Le montage de cette deuxième version de tire- bouchon à palan est extrêmement rapide et est très peu onéreux, ce qui le différencie très nettement de la précédente.The assembly of this second version of hoist corkscrew is extremely fast and is very inexpensive, which clearly differentiates it from the previous one.
