Description
APPAREIL POUR OUVRIR LES HUITRES. La présente invention a pour objet un appareil pour ouvrir les huîtres. Le secteur technique de l'invention est le domaine des ustensiles de cuisine et de table, pour aider les cuisiniers, les serveurs de plats et/ou les consommateurs de ceux-ci. à préparer les aliments et en particulier, dans la présente invention, pour ouvrir les huîtres fraîches ou autres mollusques, afin de les présenter pour être consommés dans les meilleures conditions. APPARATUS FOR OPENING OYSTERS. The present invention relates to an apparatus for opening oysters. The technical sector of the invention is the field of kitchen and table utensils, to help cooks, dish servers and / or consumers thereof. to prepare food and in particular, in the present invention, to open fresh oysters or other molluscs, in order to present them for consumption in the best conditions.
L'appareil pour ouvrir les huîtres le plus connu et le plus simple est le couteau dont on introduit la lame entre les lèvres des valves de la coquille pour couper le muscle du mollusque qui les retient fermées. L'inconvénient connu de ce moyen est la nécessité d'avoir une certaine habileté, l'introduction de la lame n'étant pas toujours aisée, et risquant de provoquer des blessures de la main.The most well-known and simplest device for opening oysters is the knife, the blade of which is inserted between the lips of the shell valves to cut the mollusc muscle which keeps them closed. The known disadvantage of this means is the need to have a certain skill, the introduction of the blade is not always easy, and may cause injury to the hand.
Pour faciliter l'introduction de la lame, certains dispositifs permettent de briser l'extrémité de la coquille, faisant ainsi un passage pour atteindre le muscle. De tels dispositifs présentent l'inconvénient que l'action de briser l'extrémité de la coquille provoque des esquilles de la nacre qui peuvent être introduites à l'intérieur de la coquille. rendant désagréable la dégustation du mollusque.To facilitate the introduction of the blade, certain devices make it possible to break the end of the shell, thus making a passage to reach the muscle. Such devices have the disadvantage that the action of breaking the end of the shell causes shells of mother-of-pearl which can be introduced inside the shell. making tasting the mollusc unpleasant.
De même, divers autres dispositifs ont été développés et ont fait l'objet de dépôts de demandes de brevets, tels que celle FR 2432289 qui décrit un appareil assez compliqué, qui doit être fixé sur un support fixe tel qu'une table, et qui nécessite pas moins de quatre mouvements successifs de quatre moyens indépendants mobiles pour obtenir le résultat souhaité; à savoir, un levier vertical muni d'une griffe qui immobile l'huître à plat dans un réceptacle, un dispositif réglable en hauteur et compensé par un ressort pour positionner la lame d'ouverture en face des lèvres de l'huître, une poignée de déplacement de la lame pour l'insérer entre lesdites lèvres et un levier articulé sur la poignée précédente et support de cette lame pour couper le muscle; de plus, la disposition d'un tel appareil présente la lame du côté diamétralement opposé à la charnière de l'huître, donc éloigné du muscle, ce qui rend difficile son sectionnement et peut abîmer la chair.Similarly, various other devices have been developed and have been the subject of patent applications, such as that FR 2432289 which describes a fairly complicated device, which must be fixed on a fixed support such as a table, and which requires no less than four successive movements of four independent movable means to obtain the desired result; namely, a vertical lever provided with a claw which immobilizes the oyster flat in a receptacle, a device adjustable in height and compensated by a spring to position the opening blade opposite the lips of the oyster, a handle moving the blade to insert it between said lips and a lever articulated on the previous handle and support of this blade to cut the muscle; in addition, the arrangement of such a device has the blade on the side diametrically opposite to the hinge of the oyster, therefore distant from the muscle, which makes it difficult to cut and can damage the flesh.
On peut citer également les brevets US 2000075 et US 2747220 qui enseignent des systèmes de type tranchoir articulé à grande lame longue, qui doit être guidée et enfilée entre les lèvres de l'huître, qui est maintenue dans un réceptacle; la lame doit être descendue entre les lèvres jusqu'à sectionner directement le muscle; mais pendant ce mouvement, comme les lèvres des huîtres ne sont jamais dans un plan rectiligne mais toujours courbe, ondulé et gauche, la lame du tranchoir ne peut que détériorer les valves du mollusque, et provoquer de nombreux éclats d'écaillés qui rendent le mollusque difficilement consommable dans de bonnes conditions..
Par ailleurs, la demande de brevet FR 2717668, qui n'est du reste pas très explicite dans sa description, enseigne un dispositif qui se rapproche de celui de la demande FR 2432289 analysée ci-dessus, à savoir avec une présentation de l'huître à plat, mais sans levier de maintien ni réglage de la hauteur de la lame, ce qui peut rendre difficile l'immobilisation et l'adaptation à différentes épaisseurs d'huîtres; la seule originalité de ce dispositif est la possibilité de régler le point d'articulation de la poignée support de la lame, non pas en hauteur mais en largeur par rapport à l'huître; cependant, la lame est courte et on ne voit pas trop comment elle peut à coup sûr, venir sectionner le muscle, sauf à en augmenter sa largeur et sa longueur comme dans les tranchoirs décrits dans les brevets américains précédents, ce qui détériorerait également les lèvres de l'huître, comme explicité ci-dessus.We can also cite the patents US 2000075 and US 2747220 which teach systems of the articulated slicer type with a large long blade, which must be guided and threaded between the lips of the oyster, which is held in a receptacle; the blade must be lowered between the lips until directly cutting the muscle; but during this movement, as the lips of the oysters are never in a rectilinear plane but always curved, wavy and left, the blade of the slicer can only deteriorate the valves of the mollusk, and cause numerous chips of scales which make the mollusk difficult to consume in good conditions. Furthermore, patent application FR 2717668, which is not very explicit in its description, teaches a device which is similar to that of application FR 2432289 analyzed above, namely with a presentation of the oyster. flat, but without holding lever or blade height adjustment, which can make it difficult to immobilize and adapt to different thicknesses of oysters; the only originality of this device is the possibility of adjusting the point of articulation of the blade support handle, not in height but in width with respect to the oyster; however, the blade is short and it is not clear how it can certainly cut the muscle, except to increase its width and length as in the slicers described in previous US patents, which would also damage the lips oyster, as explained above.
Enfin, et plus récemment, pour éviter les inconvénients ci-dessus, il a été proposé d'introduire un fil d'acier entre les valves, à l'arrière du muscle, après avoir placé l'huître dans un bain à haute concentration en sel pour provoquer l'ouverture spontanée de la coquille. Ce dispositif présente l'inconvénient d'être onéreux. Il nécessite en effet un fil pour chaque huître. Mais surtout il impose une longue manipulation. Il faut en effet tremper les huîtres un certain temps dans un bain salé, jusqu'à ce qu'elles s'ouvrent ; puis les prendre une à une pour leur introduire le fil ; enfin les tremper dans un nouveau bain pour enlever l'excès de sel. Autant de manipulations qui entraînent un coût de main d'oeuvre important pour préparer chaque huître et la munir du fil, d'où un prix de revient élevé au niveau de la production.Finally, and more recently, to avoid the above drawbacks, it has been proposed to introduce a steel wire between the valves, at the back of the muscle, after having placed the oyster in a bath with a high concentration of salt to cause spontaneous opening of the shell. This device has the disadvantage of being expensive. It indeed requires a wire for each oyster. But above all it requires a long manipulation. It is indeed necessary to soak the oysters for a certain time in a salted bath, until they open; then take them one by one to introduce the wire; finally soak them in a new bath to remove excess salt. As many manipulations which involve a significant labor cost to prepare each oyster and provide it with the wire, from where a high cost price at the level of the production.
La présente invention a pour but de supprimer chacun de ces inconvénients, grâce à un appareil utilisable directement par le consommateur, ce qui ne renchérit pas le coût de la production de l'huître, ledit appareil assurant l'ouverture de l'huître sans aucun risque de blessure pour l'utilisateur, et sans provoquer d'esquille à l'intérieur de la coquille et qui rendrait désagréable la consommation du mollusque.The object of the present invention is to eliminate each of these drawbacks, by means of an apparatus usable directly by the consumer, which does not increase the cost of producing the oyster, said apparatus ensuring the opening of the oyster without any risk of injury to the user, and without causing a scallop inside the shell and which would make consumption of the mollusc unpleasant.
Pour cela le dispositif comporte un moyen permettant de ne pas tenir l'huître à la main, mais de la placer automatiquement dans la position telle que la lame d'un couteau manoeuvré par un levier de l'appareil, pénètre directement et automatiquement par un simple mouvement de rotation du levier entre les lèvres des deux valves de l'huître fermée jusqu'à atteindre la hauteur du muscle du mollusque en avant de celui-ci par rapport à la charnière de la coquille, ledit couteau comportant un moyen qui fait alors pivoter sa lame dans la direction de ladite charnière, ce qui l'amène à sectionner automatiquement le muscle, provoquant ainsi l'ouverture de la coquille, d'où il est aisé ensuite d'en extraire la chair du mollusque pour la déguster sans esquille de nacre.
L'objectif de la présente invention est ainsi obtenu avec un appareil pour ouvrir les huîtres comportant une lame portée par un levier mobile autour d'un axe, et un moyen permettant de placer une huître de chant dans le plan perpendiculaire à cet axe et suivant lequel peut se déplacer ladite lame, de manière à la faire pénétrer entre les lèvres des deux valves de l'huître pour atteindre le muscle et le sectionner; selon la présente invention, ladite lame est de forme effilée, articulée sur ledit levier et disposée entre celui-ci et le moyen réceptacle de l'huître, et dont la tranche affûtée, par exemple opposée à l'axe dudit levier, se trouve amenée par rapprochement dudit levier vers le moyen réceptacle de l'huître, à pénétrer par sa pointe entre les lèvres des deux valves de l'huître; et un moyen assure le basculement automatique de ladite lame dans la direction de la charnière de l'huître, soit par exemple opposée à celle de l'axe dudit levier.For this, the device comprises a means making it possible not to hold the oyster in the hand, but to automatically place it in the position such that the blade of a knife operated by a lever of the apparatus, penetrates directly and automatically by a simple movement of rotation of the lever between the lips of the two valves of the closed oyster until reaching the height of the mollusc muscle in front of it relative to the hinge of the shell, said knife comprising a means which then pivot its blade in the direction of said hinge, which causes it to automatically cut the muscle, thus causing the opening of the shell, from which it is then easy to extract the flesh of the mollusk to taste it without splinting mother of pearl. The objective of the present invention is thus obtained with an apparatus for opening oysters comprising a blade carried by a lever movable around an axis, and a means making it possible to place a song oyster in the plane perpendicular to this axis and following which can move said blade, so as to make it penetrate between the lips of the two oyster valves to reach the muscle and cut it; according to the present invention, said blade is of tapered shape, articulated on said lever and disposed between the latter and the receptacle means of the oyster, and whose sharpened edge, for example opposite the axis of said lever, is brought by bringing said lever towards the oyster receptacle means, to be penetrated by its tip between the lips of the two oyster valves; and a means ensures the automatic tilting of said blade in the direction of the oyster hinge, ie for example opposite that of the axis of said lever.
Dans un mode préférentiel de réalisation, ledit moyen assurant le basculement automatique de ladite lame, est constitué par un bras solidaire de cette lame, ledit bras se développant depuis son articulation sur ledit levier, par exemple dans la direction opposée à l'axe de celui-ci, du côté et au-delà de la tranche affûtée de ladite lame; ledit bras entraîne le pivotement automatique de la lame vers ladite charnière de l'huître dès que, dans la manoeuvre dudit levier, l'extrémité dudit bras entre en contact avec le bord de l'huître sur lequel il se trouve prendre appui.In a preferred embodiment, said means ensuring the automatic tilting of said blade, is constituted by an arm integral with this blade, said arm developing from its articulation on said lever, for example in the direction opposite to the axis of that -ci, on the side and beyond the sharp edge of said blade; said arm causes the automatic pivoting of the blade towards said hinge of the oyster as soon as, in the operation of said lever, the end of said arm comes into contact with the edge of the oyster on which it is supported.
L'invention est en outre caractérisée par les détails qui ressortiront de la description qui va en être donnée.The invention is further characterized by the details which will emerge from the description which will be given thereof.
La figure 1 est une vue schématique en élévation de profil, de l'objet de l'invention, montrant en pointillés ses différents éléments en position de travail. La figure 2 est une vue schématique en élévation de face du même objet. Selon la figure 1, le dispositif comporte un moyen tel qu'un berceau 1, réalisé en creux et de forme oblongue allongée capable de recevoir une huître 11 de chant, son plan d'ouverture pouvant ainsi être placé dans le plan XX' médian vertical du dispositif.Figure 1 is a schematic side elevational view of the object of the invention, showing in dotted lines its various elements in the working position. Figure 2 is a schematic front elevation view of the same object. According to Figure 1, the device comprises a means such as a cradle 1, produced in the hollow and of elongated oblong shape capable of receiving a song oyster 11, its opening plane can thus be placed in the vertical median plane XX ' of the device.
Ledit berceau est porté par un levier 3, dont une extrémité libre 8 a une forme facilitant la prise en main.Said cradle is carried by a lever 3, a free end 8 of which has a shape which facilitates handling.
A l'autre extrémité dudit levier 3, se trouve un support 2 se dressant, par exemple perpendiculairement, au-dessus du plan supérieur horizontal du berceau 1, et de préférence dans le plan vertical XX' de symétrie de ce dernier.At the other end of said lever 3, there is a support 2 standing, for example perpendicularly, above the horizontal upper plane of the cradle 1, and preferably in the vertical plane XX 'of symmetry of the latter.
A l'extrémité libre du support 2, un autre levier 4, se terminant en forme de poignée 5, est articulé au niveau de l'axe 9 perpendiculaire audit plan XX'..At the free end of the support 2, another lever 4, ending in the shape of a handle 5, is articulated at the level of the axis 9 perpendicular to said plane XX '.
Les leviers 3-8 et 4-5 ainsi articulés l'un sur l'autre forment ensemble un genre de pince capable de recevoir une huître placée de chant dans le berceau 1, et dont la charnière 12, suivant les modes de réalisation représentés à titre d'exemples, est positionnée dans la direction opposée à l'axe 9 des leviers pour que son muscle 13 soit
situé entre cet axe et la charnière. Dans d'autres modes de réalisation, l'huître pourrait être positionnée en sens inverse, et la lame 6 et son bras 10 décrit ci-après seraient alors montés en sens opposé.The levers 3-8 and 4-5 thus articulated one on the other together form a kind of clamp capable of receiving an oyster placed in song in the cradle 1, and including the hinge 12, according to the embodiments shown in as examples, is positioned in the direction opposite to the axis 9 of the levers so that its muscle 13 is located between this axis and the hinge. In other embodiments, the oyster could be positioned in the opposite direction, and the blade 6 and its arm 10 described below would then be mounted in the opposite direction.
Dans le plan XX' qui peut être de symétrie du levier 4-5, coïncidant avec le plan médian qui peut être de symétrie du berceau 1, est articulé autour d'un axe 14 le couteau formé d'une lame 6 de forme sensiblement foliaire se développant entre le levier 4-5 et le berceau 1 sous une forme effilée se terminant par la pointe 7, et dont la tranche, opposée ici à l'articulation 9 du levier 4-5, soit du côté de la charnière 12, est affûtée.In the plane XX 'which can be of symmetry of the lever 4-5, coinciding with the median plane which can be of symmetry of the cradle 1, is articulated around an axis 14 the knife formed by a blade 6 of substantially leaf shape developing between the lever 4-5 and the cradle 1 in a tapered form ending in the point 7, and the edge of which, opposite here to the articulation 9 of the lever 4-5, ie on the side of the hinge 12, is sharpened.
La lame 6 porte par ailleurs un bras 10, qui peut être réalisé en une seule pièce comme représenté sur la figure 1, l'extrémité 20 dudit bras 10 étant d'une épaisseur préférentiellement supérieure au moins à celle de la lame elle-même, et qui se développe depuis l'articulation 14 de la lame 6 au delà de sa zone affûtée, dans la direction de la charnière 12 de la coquille, c'est-à-dire dans l'exemple représenté, à l'opposé de l'axe 9.The blade 6 also carries an arm 10, which can be produced in a single piece as shown in FIG. 1, the end 20 of said arm 10 being preferably preferably at least greater than that of the blade itself, and which develops from the articulation 14 of the blade 6 beyond its sharpened zone, in the direction of the hinge 12 of the shell, that is to say in the example shown, opposite to the axis 9.
Un ressort épingle 15 est placé au niveau de l'articulation 9 en vue de faciliter l'ouverture de la pince créée par les leviers 4-5 et 3-8.A pin spring 15 is placed at the joint 9 in order to facilitate the opening of the clamp created by the levers 4-5 and 3-8.
Le dispositif étant ainsi constitué, et étant pris en main à la manière d'une pince, une huître 11 est placée de chant dans le berceau 1, sa charnière 12 étant placée du côté de la poignée 8 du levier 3, le levier 4 étant lui-même relevé sous l'effet du ressort 15.The device being thus constituted, and being taken in hand in the manner of a clamp, an oyster 11 is placed singingly in the cradle 1, its hinge 12 being placed on the side of the handle 8 of the lever 3, the lever 4 being itself raised under the effect of spring 15.
La position de l'articulation 14 de la lame 6 sur le levier 4-5 est telle que, lors de la fermeture de la pince constituée par les leviers 3-8 et 4-5, la pointe 7 de la lame 6, qui se présente dans le plan XX' de symétrie dudit berceau 1, et qui correspond au plan séparant les lèvres des deux valves de l'huître, est alors automatiquement amenée à pénétrer entre ces lèvres jusqu'à atteindre le muscle 13, en avant de celui-ci par rapport à la charnière 12 de l'huître; la position, de celle-ci étant par exemple maintenue par une des mains de l'opérateur dans ledit berceau 1, dans une position telle que la pointe 7 se présente exactement entre les deux lèvres du mollusque.The position of the articulation 14 of the blade 6 on the lever 4-5 is such that, when closing the clamp constituted by the levers 3-8 and 4-5, the tip 7 of the blade 6, which is present in the plane XX 'of symmetry of said cradle 1, and which corresponds to the plane separating the lips of the two valves of the oyster, is then automatically caused to penetrate between these lips until reaching the muscle 13, in front of it ci relative to the hinge 12 of the oyster; the position, the latter being for example maintained by one of the operator's hands in said cradle 1, in a position such that the point 7 is exactly between the two lips of the mollusk.
Dans le mouvement de fermeture de la pince par rapprochement des deux leviersIn the closing movement of the clamp by bringing the two levers together
3-8, 4-5, et actionné éventuellement par l'autre main que celle maintenant ledit mollusque, l'extrémité 20 du bras 10 de la lame 6 entrera en contact avec le bord de la coquille. La surépaisseur 20 qui lui a été donnée l'empêche plus facilement de pénétrer entre les lèvres.3-8, 4-5, and optionally actuated by the other hand than that holding said mollusk, the end 20 of the arm 10 of the blade 6 will come into contact with the edge of the shell. The extra thickness 20 which has been given to it more easily prevents it from penetrating between the lips.
En continuant l'effort de fermeture de la pince, cette extrémité 20 du levier 10 prenant alors appui sur la coquille et glissant sur le bord de celle-ci, grâce par exemple à une forme de type arrondi et d'axe perpendiculaire auxdites lèvres, fera basculer la lame 6 autour de son axe de rotation 14 de manière à la faire pivoter vers la charnière 12 de l'huître, l'amenant ainsi à sectionner, grâce à sa longueur suffisante pour cela, le muscle
13 qu'elle rencontre, ce qui provoquera l'ouverture instantanée de la coquille dont on pourra séparer les valves à la main.By continuing the force of closing the clamp, this end 20 of the lever 10 then taking support on the shell and sliding on the edge of the latter, thanks for example to a shape of rounded type and of axis perpendicular to said lips, will tilt the blade 6 around its axis of rotation 14 so as to pivot it towards the hinge 12 of the oyster, thus causing it to cut, thanks to its sufficient length for this, the muscle 13 that it meets, which will cause the instantaneous opening of the shell from which the valves can be separated by hand.
L'ouverture peut donc être considérée automatique sans qu'à aucun moment l'opérateur n'ait couru le moindre risque de se blesser, sans qu'aucune esquille de nacre ne soit introduite dans le mollusque et avec l'assurance que la lame 6 vienne toujours couper le muscle 13, du fait de l'amplitude de son mouvement de rotation et sa longueur définie assez grande par tout homme de métier connaissant les huîtres, pour être sûr de rencontrer le muscle 13 et le sectionner.The opening can therefore be considered automatic without at any time the operator has run the slightest risk of injury, without any shell of mother-of-pearl being introduced into the mollusk and with the assurance that the blade 6 always cut muscle 13, because of the amplitude of its rotational movement and its length defined large enough by any person skilled in the art knowing oysters, to be sure to meet muscle 13 and cut it.
La surépaisseur 20 du bras 10 peut être constituée par une pièce rapportée de forme cylindrique par exemple, ayant un bon coefficient de glissement par rapport à la surface de l'huître. Il peut être également rajouté un ressort de rappel soit sur l'axe de rotation 14, soit entre le bras 10 et le levier 5 de la pince : ce ressort ramène ladite lame 6 en position de pénétration entre les lèvres d'un mollusque, pour qu'entre deux opérations d'ouverture, l'opérateur n'ait pas à ramener manuellement ladite lame dans cette position après sa rotation pour couper le muscle 13.The extra thickness 20 of the arm 10 can be constituted by an insert of cylindrical shape for example, having a good coefficient of sliding relative to the surface of the oyster. It is also possible to add a return spring either on the axis of rotation 14, or between the arm 10 and the lever 5 of the clamp: this spring brings said blade 6 back into the penetration position between the lips of a mollusk, to that between two opening operations, the operator does not have to manually return said blade to this position after its rotation to cut the muscle 13.
Accessoirement le dispositif comporte un anneau 16 permettant de maintenir la pince fermée en période de non-emploi. De même il peut comporter un tire-bouchon 17 articulé autour de l'axe 18 et contenu dans le logement 19 pratiqué dans le support 2.
Incidentally, the device includes a ring 16 making it possible to keep the clamp closed during periods of non-use. Similarly, it may include a corkscrew 17 articulated around the axis 18 and contained in the housing 19 formed in the support 2.
