Description

La présente invention concerne un couteau électrique destiné notamment à l'ouverture des huitres et plus particulièrement un tel couteau du type comprenant un boîtier, une lame susceptible de coulisser dans sa direction longitudinale entre une position sortie par rapport au boîtier et une position rentrée par rapport au boîtier, et un électro-aimant monté dans le boîtier et agencé pour faire vibrer la lame entre ses deux positions.The present invention relates to an electric knife intended in particular for the opening of oysters and more particularly such a knife of the type comprising a housing, a blade capable of sliding in its longitudinal direction between an extended position relative to the housing and a retracted position relative to the housing, and an electromagnet mounted in the housing and arranged to vibrate the blade between its two positions.

De tels appareils sont déjà connus dans la technique. Ils permettent, du fait des vibrations de la lame, d'introduire cette dernière plus aisément entre les deux valves du coquillage et ainsi de faciliter son ouverture.Such devices are already known in the art. They allow, due to the vibrations of the blade, to introduce the latter more easily between the two valves of the shell and thus facilitate its opening.

Ces appareils connus présentent toutefois l'inconvénient de manquer généralement de puissance et d'être par conséquent relativement peu fiables.These known devices however have the disadvantage of generally lacking in power and therefore being relatively unreliable.

La présente invention vise à pallier cet inconvénient.The present invention aims to overcome this drawback.

A cet effet, l'invention a pour objet un couteau électrique destiné notamment à l'ouverture des huitres, du type comprenant un boîtier, une lame susceptible de coulisser dans sa direction longitudinale entre une position sortie par rapport au boîtier et une position rentrée par rapport au boîtier, et un électro-aimant monté dans le boîtier et agencé pour faire vibrer la lame entre ses deux positions, caractérisé par le fait qu'il comporte une came montée à rotation sur le boîtier, ladite came étant susceptible de vibrer en rotation sous l'action de l'électro-aimant entre une première position où elle impose à la lame d'être en position sortie, et une seconde position où elle permet à la lame de reprendre sa position rentrée.To this end, the invention relates to an electric knife intended in particular for opening oysters, of the type comprising a housing, a blade capable of sliding in its longitudinal direction between an extended position relative to the housing and a retracted position by relative to the housing, and an electromagnet mounted in the housing and arranged to vibrate the blade between its two positions, characterized in that it comprises a cam mounted to rotate on the housing, said cam being capable of vibrating in rotation under the action of the electromagnet between a first position where it requires the blade to be in the extended position, and a second position where it allows the blade to return to its retracted position.

Ainsi, lorsque la came vibre sous l'action de l'électro-aimant, elle entraîne la lame vers sa position sortie lorsqu'elle prend sa première position, puis permet à la lame de revenir à sa position rentrée sous l'effet de la pression exercée par l'utilisateur lorsqu'elle revient vers sa deuxième position.Thus, when the cam vibrates under the action of the electromagnet, it drives the blade towards its extended position when it takes its first position, then allows the blade to return to its retracted position under the effect of the pressure exerted by the user when it returns to its second position.

Avantageusement le couteau selon l'invention comprend des premiers moyens élastiques maintenant la came à proximité de sa seconde position en l'absence de forces magnétiques.Advantageously, the knife according to the invention comprises first elastic means keeping the cam close to its second position in the absence of magnetic forces.

Ainsi, la came reste dans cette seconde position tant que l'électro-aimant n'est pas excité. Dès que celui-ci est excité, les forces êlectro-magnétiques attirent la came en direction de sa première position, ce qui a pour effet d'amorcer le mouvement de vibration qui peut être transmis à la lame.Thus, the cam remains in this second position as long as the electromagnet is not energized. As soon as the latter is excited, the electromagnetic forces attract the cam towards its first position, which has the effect of initiating the vibration movement which can be transmitted to the blade.

Des seconds moyens élastiques peuvent également être prévus pour ramener ladite lame dans sa position sortie.Second elastic means can also be provided to return said blade to its extended position.

Ainsi, lorsqu'aucun effort n'est exercé sur la lame, celle-ci est maintenue dans sa position sorrie. La came peut par conséquent vibrer sans que ses vibrations ne soient transmises à In lame, ce qui assure un fonctionnement silencieux de l'appareil.Thus, when no force is exerted on the blade, the latter is maintained in its outgoing position. The cam can therefore vibrate without that its vibrations are not transmitted to In lame, which ensures silent operation of the device.

Lorsqu'un effort prédéterminé permettant de vaincre l'action des seconds moyens élastiques est exercé par l'utilisateur sur la lame, celle-ci quitte sa position sortie pour rentrer légèrement à l'intérieur du boîtier de l'appareil. La came vient alors à son contact à chaque fois qu'elle arrive dans sa première position, et provoque ainsi ses vibrations.When a predetermined force allowing the action of the second elastic means to be overcome is exerted by the user on the blade, the latter leaves its extended position to return slightly inside the housing of the device. The cam then comes into contact with it each time it arrives in its first position, and thus causes its vibrations.

Avantageusement, le rapport de la distance entre l'axe de rotation de la came et l'entrefer de l'électro-aimant d'une part, à la distance entre l'axe de rotation de la came et sa partie agissant sur la lame d'autre part, est compris entre deux et trois pour optimiser le fonctionnement du couteau selon l'invention.Advantageously, the ratio of the distance between the axis of rotation of the cam and the air gap of the electromagnet on the one hand, to the distance between the axis of rotation of the cam and its part acting on the blade on the other hand, is between two and three to optimize the operation of the knife according to the invention.

On décrira maintenant à titre d'exemple non limitatif un mode de réalisation particulier de l'invention en référence aux dessins schématiques annexés représentant une vue partielle ouverte d'un couteau électrique selon l'invention.A particular embodiment of the invention will now be described by way of nonlimiting example with reference to the appended schematic drawings showing a partial open view of an electric knife according to the invention.

La figure représente le boitier 1 de l'appareil à l'intérieur duquel est monté un électro-aimant 2 alimenté par un cordon d'alimentation 3 de façon connue.The figure shows the housing 1 of the device inside which is mounted an electromagnet 2 supplied by a power cord 3 in known manner.

L'électro-aimant 2 comporte deux pièces polaires 4 présentant des surfaces cylindriques 5 centrées sur un axe 6.The electromagnet 2 comprises two pole pieces 4 having cylindrical surfaces 5 centered on an axis 6.

Une came 7 est montée à rotation dans le boîtier 1 autour d'un arbre 8 également centré sur l'axe 6.A cam 7 is rotatably mounted in the housing 1 around a shaft 8 also centered on the axis 6.

Un aimant permanent 9 est fixé à la came 7 avec ses deux pôles en vis-à-vis des pièces polaires 4 de l'électro-aimant 2 lorsque la came est dans une première position représentée aux dessins en traits pleins.A permanent magnet 9 is fixed to the cam 7 with its two poles facing the pole pieces 4 of the electromagnet 2 when the cam is in a first position shown in the drawings in solid lines.

Deux ressorts de compression 10 tendent à écarter la came 7 de cette première position pour la maintenir en équilibre, en l'absence de forces magnétiques, dans une seconde position représentée au dessin en traits mixtes.Two compression springs 10 tend to separate the cam 7 from this first position to keep it in balance, in the absence of magnetic forces, in a second position shown in the drawing in phantom.

La came 7 possède une surface de came 11 susceptible de coopérer avec le talon 12 d'une lame 13 montée coulissante dans le boîtier 1 entre une position sertie représentée en traits pleins et une position rentrée représentée en traits mixtes.The cam 7 has a cam surface 11 capable of cooperating with the heel 12 of a blade 13 slidably mounted in the housing 1 between a crimped position shown in solid lines and a retracted position shown in broken lines.

Le coulissement de la lame 13 est guidé par des surfaces 14 du beîtier coopérant avec des surfaces correspondantes du talon 12.The sliding of the blade 13 is guided by surfaces 14 of the housing cooperating with corresponding surfaces of the heel 12.

Des ressorts de compression 15 agissant entre des épaulements 16 du bottier et le talon 12 de la lame 13 ont tendance à maintenir cette lame dans sa position sortie. ,Compression springs 15 acting between the shoulders 16 of the bootmaker and the heel 12 of the blade 13 tend to keep this blade in its extended position. ,

Du fait de la forme de la surface de came Il qui présente une saillie 17, le couteau 13 est également maintenu dans sa position sortie par la came 7 lorsque celle-ci est dans sa première position.Due to the shape of the cam surface II which has a projection 17, the knife 13 is also held in its extended position by the cam 7 when the latter is in its first position.

Par contre, lorsque la came 7 vient dans sa seconde position représentée en trait mixte aux dessins, la saillie 17 s'efface et le couteau 13 peut sous l'action d'une force longitudinale F antagoniste à la force exercée par les ressorts 15 venir dans sa position rentrée. Ainsi, lorsque l'électro-aimant 2 est alimenté il provoque une vibration en rotation de la came 7 entre ses deux positions représentées au dessin respectivement en traits pleins et en traits mixtes, qui entraîne à son tour une vibration de la lame 13 si un force F est exercée sur celle-ci par l'utilisateur.By cons, when the cam 7 comes into its second position shown in phantom in the drawings, the projection 17 disappears and the knife 13 can under the action of a longitudinal force F antagonistic to the force exerted by the springs 15 come in its retracted position. Thus, when the electromagnet 2 is supplied, it causes a vibration in rotation of the cam 7 between its two positions shown in the drawing respectively in solid lines and in dashed lines, which in turn causes the blade 13 to vibrate if a force F is exerted on it by the user.

Par contre, si aucune force n'est exercée, la lame 13 reste dans sa position sortie sous l'action des ressorts 15 et ne reçoit pas les vibrations de la came.On the other hand, if no force is exerted, the blade 13 remains in its extended position under the action of the springs 15 and does not receive the vibrations of the cam.

Il a par ailleurs été constaté que l'efficacité du couteau selon l'invention était optimale lorsque le rapport D/d était compris entre 2 et 3, D étant la distance entre l'axe 6 de rotation de la came et les surfaces 5 des pièces polaires 4 de l'électro-aimant et d étant la distance entre ce même axe 6 et la saillie 17 de la came.It has also been found that the efficiency of the knife according to the invention was optimal when the ratio D / d was between 2 and 3, D being the distance between the axis 6 of rotation of the cam and the surfaces 5 of the pole pieces 4 of the electromagnet and d being the distance between this same axis 6 and the projection 17 of the cam.

Bien entendu diverses variantes et modifications peuvent être apportées au mode de réalisation décrit ci-dessus sans sortir pour autant du cadre ni de l'esprit de l'invention.Of course, various variants and modifications can be made to the embodiment described above without departing from the scope or the spirit of the invention.

C'est ainsi par exemple que les ressorts 10 pourraient être remplacés par un ressort spirale ou même éventuellement supprimés. De même, la came 7 a été représenté agissant directement sur le talon du couteau 13, mais une pièce intermédiaire pourrait évidemment être ajoutée.Thus, for example, the springs 10 could be replaced by a spiral spring or even possibly eliminated. Similarly, the cam 7 has been shown acting directly on the heel of the knife 13, but an intermediate piece could obviously be added.
