Domaine techniqueTechnical area

La présente invention concerne un ustensile manuel, étant un article de vaisselle tel qu'un composant d'un couvert de table, ledit ustensile comprenant deux éléments constitutifs, d'une part, une pièce d'extrémité fonctionnelle et, d'autre part, un manche amovible, lesdits éléments constitutifs étant équipés d'organes d'emboîtement complémentaires agencés pour les coupler de façon amovible, l'un desdits éléments constitutifs étant pourvu d'un embout, l'autre desdits éléments constitutifs étant pourvu d'une douille agencée pour recevoir ledit embout, ladite pièce d'extrémité fonctionnelle comportant une première rampe transversale et ledit manche comportant une seconde rampe transversale de forme complémentaire à celle de la première rampe transversale pour permettre une juxtaposition desdites deux rampes transversales, la forme de ces rampes transversales étant définie pour provoquer un déplacement axial relatif des deux éléments constitutifs lorsque l'un est tourné autour de son axe par rapport à l'autre, lesdits organes d'emboîtement complémentaires comportant en outre un dispositif de verrouillage agencé pour lier l'un des éléments constitutifs par rapport à l'autre, lorsque ces deux éléments constitutifs sont couplés au moyen desdits organes d'emboîtement complémentaires de la pièce d'extrémité fonctionnelle et dudit manche.The present invention relates to a manual utensil, being a ware item such as a table top component, said utensil comprising two components, on the one hand, a functional end piece and, on the other hand, a removable handle, said constituent elements being equipped with complementary interlocking members arranged to detachably couple them, one of said constituent elements being provided with a tip, the other of said constituent elements being provided with an arranged sleeve to receive said tip, said functional end piece having a first transverse ramp and said handle having a second transverse ramp of complementary shape to that of the first transverse ramp to allow a juxtaposition of said two transverse ramps, the shape of these transverse ramps being defined to cause relative axial displacement of the two constituent elements when one is rotated about its axis relative to the other, said complementary interlocking members further comprising a locking device arranged to link one of the constituent elements with respect to the other, when these two constituent elements are coupled by means of said complementary interlocking members of the functional end piece and said handle.

Technique antérieurePrior art

On connaît déjà un ustensile de ce type, décrit par le brevet européen publié sous le N° EP 1 358 970 de la demanderesse dont une application particulièrement importante concerne les couverts de table dans le domaine appelé "l'art de la table". L'une des originalités de ce produit réside dans le fait que le manche est interchangeable, ce qui permet d'adapter les couverts au décor de table réalisé en fonction des circonstances ou des événements.We already know a device of this type, described by the European patent published under No. EP 1 358 970 of the applicant, a particularly important application relates to the table cutlery in the field called "the art of the table". One of the originalities of this product lies in the fact that the handle is interchangeable, which allows to adapt the cutlery to the table decor made according to circumstances or events.

Dans l'outil ou l'ustensile défini par le brevet ci-dessus la force de liaison des deux éléments constitutifs est obtenue essentiellement par l'attraction magnétique de deux aimants qui sont incrustés respectivement dans chacun de ces deux éléments. Le couplage résultant assure une force de maintien en position relative des deux éléments constitutifs, à savoir de la pièce fonctionnelle et du manche, qui est en principe suffisante pour un usage courant. Néanmoins, dans certaines circonstances, la contrainte peut être supérieure à la tenue mécanique obtenue par le couplage magnétique et les deux éléments constitutifs peuvent se désassembler, ou du moins partiellement s'écarter l'un de l'autre.In the tool or the tool defined by the above patent the binding force of the two constituent elements is obtained essentially by the magnetic attraction of two magnets which are respectively embedded in each of these two elements. The resulting coupling provides a holding force in the relative position of the two components, namely the functional part and the handle, which is in principle sufficient for common use. Nevertheless, under certain circumstances, the stress may be greater than the mechanical strength obtained by the magnetic coupling and the two constituent elements may disassemble, or at least partially deviate from each other.

Cet effet constitue un inconvénient non acceptable pour des produits, tels que des couverts de table, qui sont considérés comme des produits de luxe et pour lesquels la moindre désolidarisation du manche par rapport à la pièce d'extrémité fonctionnelle, cuillère, fourchette ou couteau serait considérée comme un défaut inacceptable.This effect is an unacceptable disadvantage for products, such as table cutlery, which are considered luxury products and for which the least separation of the handle with respect to the functional end piece, spoon, fork or knife would be considered an unacceptable defect.

Exposé de l'inventionPresentation of the invention

La présente invention vise à pallier l'inconvénient mentionné ci-dessus et qui est inhérent à l'art antérieur, en remplaçant ou en complétant les moyens de couplage magnétique par un couplage mécanique.The present invention aims to overcome the drawback mentioned above and which is inherent in the prior art, by replacing or supplementing the magnetic coupling means by mechanical coupling.

Dans ce but, l'ustensile manuel de l'invention tel que défini en préambule est caractérisé en ce que ledit dispositif de verrouillage comporte deux protubérances périphériques sensiblement radiales ménagées sur l'un desdits organes d'emboîtement complémentaires et deux gorges axiales ménagées dans l'autre desdits organes d'emboîtement complémentaires, lesdites gorges étant agencées pour recevoir et bloquer en position lesdites protubérances périphériques sensiblement radiales lorsque les deux éléments constitutifs sont couplés au moyen desdits organes d'emboîtement complémentaires de la pièce d'extrémité fonctionnelle et dudit manche.For this purpose, the manual utensil of the invention as defined in the preamble is characterized in that said locking device comprises two substantially radial peripheral protuberances formed on one of said complementary interlocking members and two axial grooves formed in the other of said complementary interlocking members, said grooves being arranged to receive and lock in position said substantially radial peripheral protuberances when the two constituent elements are coupled by means of said complementary interlocking members of the functional end piece and said handle.

Selon une forme de réalisation préférée, lesdites protubérances périphériques sensiblement radiales comportent chacune un picot approximativement cylindrique. Lesdits picots cylindriques ont avantageusement des diamètres différents.According to a preferred embodiment, said substantially radial peripheral protuberances each comprise an approximately cylindrical pin. These cylindrical pins advantageously have different diameters.

Lesdites gorges axiales sont avantageusement ménagées dans une douille disposée longitudinalement, parallèle à l'axe dudit organe d'emboîtement correspondant, et ont des sections différentes correspondant respectivement aux diamètres desdits picots.Said axial grooves are advantageously formed in a sleeve disposed longitudinally, parallel to the axis of said corresponding interlocking member, and have different sections respectively corresponding to the diameters of said pins.

Selon un mode de réalisation particulier, ladite douille longitudinale est constituée d'un premier secteur, dit secteur de guidage, et d'un second secteur, dit secteur de verrouillage, ledit secteur de guidage comportant lesdites gorges qui ont un profil similaire à celui desdits picots et ledit secteur de verrouillage ayant, sur un premier tronçon, des parois latérales souples et élastiques qui définissent un étranglement de section légèrement inférieure à celle desdits picots et sur un second tronçon, des parois latérales qui définissent un logement sensiblement circulaire dont le diamètre est sensiblement égal à la section des picots de l'embout.According to a particular embodiment, said longitudinal sleeve consists of a first sector, said guide sector, and a second sector, said locking sector, said guide sector comprising said grooves which have a profile similar to that of said pins and said locking sector having, on a first section, flexible and resilient sidewalls which define a throat section slightly smaller than that of said pins and a second section, side walls which define a substantially circular housing whose diameter is substantially equal to the section of the pins of the tip.

Lesdits éléments constitutifs sont de préférence équipés d'organes d'emboîtement complémentaires agencés pour les coupler de façon amovible, et comportent en outre respectivement un premier aimant et un second aimant, ledit second aimant étant agencé pour entrer dans une zone d'attraction magnétique dudit premier aimant lorsque ledit embout de l'un desdits éléments constitutifs est engagé dans ladite douille de l'autre desdits éléments constitutifs.Said constituent elements are preferably equipped with complementary interlocking members arranged to detachably couple them, and furthermore comprise respectively a first magnet and a second magnet, said second magnet being arranged to enter a zone of magnetic attraction of said first magnet when said tip of one of said constituent elements is engaged in said socket of the other of said constituent elements.

Lesdits premier et second aimants d'une part et le dispositif de verrouillage de l'un des éléments constitutifs par rapport à l'autre d'autre part sont agencés pour que le couplage des deux éléments constitutifs s'effectue sensiblement simultanément par attraction magnétique et par verrouillage mécanique.Said first and second magnets on the one hand and the locking device of one of the constituent elements relative to the other on the other hand are arranged so that the coupling of the two constituent elements takes place substantially simultaneously by magnetic attraction and by mechanical locking.

Ladite première rampe transversale de la pièce d'extrémité fonctionnelle et ladite seconde rampe transversale sont avantageusement de forme complémentaire dudit manche et comportent au moins un secteur incurvé.Said first transverse ramp of the functional end piece and said second transverse ramp are advantageously of complementary shape of said handle and comprise at least one curved sector.

Le rayon le rayon de courbure du secteur incurvé des rampes transversales est avantageusement défini de telle manière qu'une rotation relative de l'un des deux éléments constitutifs autour de son axe provoque un déplacement axial relatif de ces éléments.The radius of the radius of curvature of the curved sector of the transverse ramps is advantageously defined in such a way that a relative rotation of one of the two constituent elements around its axis causes a relative axial displacement of these elements.

Meilleures manières de réaliser l'inventionBest ways to achieve the invention

En référence à la figure 1A, l'ustensile selon l'invention se présente sous la forme d'un composant d'un couvert de table et plus particulièrement sous celle d'une cuillère 10 qui comporte une pièce d'extrémité fonctionnelle 11 et un manche amovible 12 qui constituent les éléments constitutifs de la cuillère 10, ces éléments constitutifs étant équipés d'organes d'emboîtement complémentaires agencés pour les coupler de façon amovible. L'intérêt de réaliser des couverts en deux éléments amovibles est de permettre de modifier l'aspect, le style, le décor en vue d'adapter une décoration de table selon les circonstances d'un repas. A cet effet il convient de développer des moyens de couplage des deux éléments, ces moyens devant être à la fois discrets et efficaces, c'est-à-dire quasi invisibles pour les utilisateurs et d'une résistance à toute épreuve pour éviter une quelconque désolidarisation accidentelle des deux éléments.With reference to the Figure 1A , the utensil according to the invention is in the form of a component of a table cover and more particularly that of a spoon 10 which comprises a functional end piece 11 and a removable handle 12 which constitute the components of the spoon 10, these components being equipped with complementary interlocking members arranged to couple removably. The interest of making cutlery in two removable elements is to allow to change the appearance, style, decor to adapt a table decoration according to the circumstances of a meal. For this purpose it is necessary to develop coupling means of the two elements, these means must be both discrete and effective, that is to say, almost invisible to users and resistance to any test to avoid any accidental separation of the two elements.

La figure 1B montre la cuillère 10 assemblée et illustre les moyens de couplage des deux éléments constitutifs de cette cuillère. Ces moyens seront décrits plus en détail en référence aux figures 2 et 3. La pièce d'extrémité fonctionnelle 11 est, dans ce cas, équipée d'un embout 13 qui est soit réalisé avec cette pièce, soit usiné ou moulé séparément et solidarisé avec cette pièce par des techniques connues en soi. Le manche 12 est, dans ce cas, équipé d'une douille 14 agencée pour recevoir et loger ledit embout 13. A cet effet, ladite douille 14 comporte au moins un tronçon creux 14a de section circulaire dont le diamètre est légèrement supérieur au diamètre extérieur d'un tronçon de section circulaire 13a correspondant de l'embout 13. La douille 14 peut être usinée ou moulée séparément et mise en place dans un alésage approprié ménagé dans le manche 12 ou pourrait être remplacée par un alésage ayant un profil correspondant sensiblement à celui de l'embout 13.The Figure 1B shows the spoon 10 assembled and illustrates the coupling means of the two components of this spoon. These means will be described in more detail with reference to figures 2 and 3 . The functional end piece 11 is, in this case, equipped with a tip 13 which is either made with this piece, or machined or molded separately and secured to this piece by techniques known per se. The handle 12 is, in this case, equipped with a sleeve 14 arranged to receive and accommodate said tip 13. For this purpose, said sleeve 14 comprises at least one hollow section 14a of circular section whose diameter is slightly greater than the outside diameter of a corresponding section of circular section 13a of the nozzle 13. The sleeve 14 can be machined or molded separately and placed in a suitable bore in the sleeve 12 or could be replaced by a bore having a profile corresponding substantially to that of the mouthpiece 13.

Pour compléter et renforcer l'assemblage de la pièce d'extrémité fonctionnelle 11 et du manche 12, la douille 14 est équipée d'un aimant 34, sous la forme d'une pièce cylindrique enchâssée à l'intérieur de ladite douille et l'embout 13 est équipé d'un aimant 33, également en forme de pièce cylindrique, fixé dans son extrémité coopérant avec la douille 14. Ces deux aimants sont agencés pour s'attirer et pour compléter ou renforcer la liaison entre les deux éléments constitutifs de la cuillère 10 et, le cas échéant, constituer des moyens de fixation supplémentaires par rapport aux autres moyens qui seront décrits plus en détail ci-après.To complete and strengthen the assembly of the functional end piece 11 and the handle 12, the sleeve 14 is equipped with a magnet 34, in the form a cylindrical piece embedded in said socket and the end piece 13 is equipped with a magnet 33, also in the form of a cylindrical piece, fixed in its end cooperating with the sleeve 14. These two magnets are arranged for s attract and to complete or strengthen the connection between the two components of the spoon 10 and, if necessary, provide additional fastening means compared to other means which will be described in more detail below.

La figure 1C montre la cuillère 10 désassemblée et représente plus particulièrement la pièce d'extrémité fonctionnelle 11 pourvue de l'embout 13 destiné au couplage de cette pièce avec le manche 12. On notera que l'embout 13, formant l'un des organes d'emboîtement et illustré plus en détail par la figure 2, a une forme cylindrique de section circulaire et comporte sur son tronçon 13a au moins une protubérance sous la forme d'un picot 15 sensiblement cylindrique disposé perpendiculairement à l'axe de la cuillère 10. Un second picot 16 peut être prévu et disposé dans ce cas de façon diamétralement opposée au picot 15. Le picot 15 ou les picots 15 et 16 sont agencés pour pouvoir coulisser dans des gorges correspondantes de la douille 14, formant l'autre organe d'emboîtement, afin d'assurer le guidage de l'embout 13 de l'extrémité fonctionnelle 11 dans la douille 14 du manche 12 lors du couplage des deux éléments constitutifs. Par ce moyen on assure un positionnement relatif correct des deux éléments. Pour améliorer ce positionnement lorsque l'embout 13 est pourvu de deux picots 15 et 16, lesdits picots ne sont pas identiques et le picot 16 présente un diamètre supérieur à celui du picot 15.The figure 1C shows the spoon 10 disassembled and more particularly represents the functional end piece 11 provided with the nozzle 13 for coupling this piece with the handle 12. Note that the tip 13, forming one of the interlocking members and illustrated in more detail by the figure 2 , has a cylindrical shape of circular section and has on its portion 13a at least one protuberance in the form of a substantially cylindrical pin 15 disposed perpendicularly to the axis of the spoon 10. A second pin 16 may be provided and disposed in this The pin 15 or pins 15 and 16 are arranged to slide in corresponding grooves of the sleeve 14, forming the other interlocking member, to ensure the guiding of the endpiece 13 of the functional end 11 in the sleeve 14 of the handle 12 during the coupling of the two constituent elements. By this means a correct relative positioning of the two elements is ensured. To improve this positioning when the tip 13 is provided with two pins 15 and 16, said pins are not identical and the pin 16 has a diameter greater than that of the pin 15.

La pièce d'extrémité fonctionnelle 11 et le manche 12 comportent respectivement une rampe 11a et une rampe 12a qui présentent des formes complémentaires de manière à se juxtaposer lorsque les deux éléments sont assemblés. Ces rampes comportent avantageusement au moins un secteur incurvé dont le rayon de courbure peut varier entre quelques millimètres, par exemple cinq millimètres, et l'infini. Dans ce dernier cas, les rampes sont planes et la rotation relative de l'un des éléments par rapport à l'autre n'induit aucun déplacement axial relatif. En revanche si le rayon de courbure est faible, une rotation relative engendre un déplacement axial relatif plus important des deux éléments.The functional end piece 11 and the handle 12 respectively comprise a ramp 11a and a ramp 12a which have complementary shapes so as to juxtapose when the two elements are assembled. These ramps advantageously comprise at least one curved sector whose radius of curvature may vary between a few millimeters, for example five millimeters, and infinity. In the latter case, the ramps are flat and the relative rotation of one of the elements relative to the other induces no relative axial displacement. On the other hand, if the radius of curvature is small, a relative rotation causes a greater relative axial displacement of the two elements.

Les figures 3A et 3B représentent plus en détail le dispositif de verrouillage pour lier l'un des éléments constitutifs, à savoir la pièce d'extrémité fonctionnelle 11 et le manche 12, lorsque ces deux éléments constitutifs sont couplés au moyen desdits organes d'emboîtement complémentaires. En termes généraux, le dispositif de verrouillage se compose d'une protubérance périphérique disposée radialement et ménagée sur l'un desdits organes d'emboîtement complémentaires, et un évidement ménagé sur l'autre desdits organes d'emboîtement complémentaires, cet évidement étant agencé pour recevoir ladite protubérance. Dans la présente réalisation, la protubérance périphérique a la forme d'un segment de tige cylindrique ou celle du picot 15 dressé perpendiculairement à la périphérie de l'embout 13. Le second picot 16, diamétralement opposé ou non, est prévu pour parfaire le guidage de l'embout 13 dans la douille 14. A cet effet, la douille 14 est constituée d'un premier secteur, dit secteur de guidage 20, et d'un second secteur, dit secteur de verrouillage 21, ledit secteur de guidage 20 comportant au moins une gorge axiale 22, ménagée dans le tronçon creux 14a, qui a un profil similaire à celui dudit picot 15, et ledit secteur de verrouillage 21 ayant, sur un premier tronçon 23, des parois latérales souples et élastiques 23a et 23b qui définissent un étranglement 24 de section légèrement inférieure à celle dudit picot 15 et sur un second tronçon 25, des parois latérales qui définissent un logement 26 sensiblement circulaire dont le diamètre est sensiblement égal à la section du picot 15. Le tronçon creux 14a du secteur de guidage 20 peut comporter une seconde gorge intérieure 22a, éventuellement diamétralement opposée à la gorge 22 ayant un profil similaire à celui dudit picot 16 pour assurer le guidage dudit picot 16. Dans ce cas, les autres composants du guidage et du verrouillage correspondant au picot 16 doivent également être présents.The Figures 3A and 3B show in more detail the locking device for linking one of the constituent elements, namely the functional end piece 11 and the handle 12, when these two components are coupled by means of said complementary interlocking members. In general terms, the locking device consists of a circumferential protuberance arranged radially and formed on one of said complementary interlocking members, and a recess provided on the other of said complementary interlocking members, this recess being arranged to receive said protuberance. In the present embodiment, the peripheral protuberance is in the form of a cylindrical rod segment or that of the pin 15 erected perpendicular to the periphery of the nozzle 13. The second pin 16, diametrically opposite or not, is provided to complete the guidance of the nozzle 13 in the socket 14. For this purpose, the sleeve 14 consists of a first sector, said guide sector 20, and a second sector, said locking sector 21, said guide sector 20 comprising at least one axial groove 22, formed in the hollow section 14a, which has a profile similar to that of said pin 15, and said locking sector 21 having, on a first section 23, flexible and resilient lateral walls 23a and 23b which define a throat 24 of section slightly smaller than that of said pin 15 and a second section 25, side walls which define a substantially circular housing 26 whose diameter is substantially equal to the section 15. The hollow section 14a of the guide sector 20 may comprise a second internal groove 22a, possibly diametrically opposite the groove 22 having a profile similar to that of said pin 16 to guide said pin 16. In this case, the other components of the guide and the lock corresponding to the pin 16 must also be present.

D'autres solutions sont envisageables, notamment des dispositifs de verrouillage du type à baïonnette avec lesquels les deux éléments constitutifs doivent être engagés axialement et ensuite tournés l'un par rapport à l'autre. Le verrouillage mécanique combiné avec le verrouillage magnétique constitue une solution très sûre et très efficace, même si cette combinaison n'est pas une nécessité absolue.Other solutions are conceivable, including bayonet type locking devices with which the two components must be engaged axially and then rotated relative to each other. Mechanical locking combined with magnetic locking is a very safe and effective solution, although this combination is not an absolute necessity.
