Abstract

The device has a part (4) fixed to a handle (3) or a knife guard (2) and having an end terminated by a point (7) surrounded by sharp blades (5, 6). A knife is held by a user using the handle to support the point at a joint of two valves of oysters. The user carries out a continuous and alternate movement of the handle in clockwise direction and then in opposite direction to exert a pressure on the point for breaking an oyster shell.

Description

2875115 12875115 1

La présente invention concerne un dispositif pour faciliter et sécuriser l'ouverture des huîtres et des mollusques.  The present invention relates to a device for facilitating and securing the opening of oysters and molluscs.

L'ouverture des huîtres se fait traditionnellement avec un couteau à huître ce qui risque de blesser l'utilisateur inexpérimenté.  The opening of oysters is traditionally done with an oyster knife which may hurt the inexperienced user.

Le dispositif selon l'invention comporte une pièce (4), inoxydable de préférence, de 5 à 6 mm de diamètre environ, fixée au manche (3) d'un couteau ou à sa garde (figures 1, 5, 6) (2).  The device according to the invention comprises a piece (4), preferably stainless, approximately 5 to 6 mm in diameter, fixed to the handle (3) of a knife or in its guard (FIGS. 1, 5, 6) (2). ).

Son extrémité dont le détail est vu agrandi sur les figures 2, 3 et 4, comporte au centre une pointe (7) de type pyramidal, aux arêtes acérées.  Its end whose detail is seen enlarged in Figures 2, 3 and 4, has in the center a tip (7) of pyramidal type with sharp edges.

Cette pointe (7) d'une longueur de 2 à 3 mm environ est entourée de deux ailettes (5) et (6) acérées, un peu plus courte que la pointe.  This tip (7) of a length of 2 to 3 mm is surrounded by two wings (5) and (6) sharp, a little shorter than the tip.

La disposition et la forme de ces ailettes sont montrées sur les figures 2,3et4.  The arrangement and shape of these fins are shown in Figures 2,3 and 4.

L'utilisateur tient le couteau par le manche, le pouce appuyé sur la garde (2), ce qui lui donne une meilleure prise (figure 5).  The user holds the knife by the handle, thumb pressed on the guard (2), which gives it a better grip (Figure 5).

L'utilisateur appuie la pointe (7) à la jointure des deux valves, vers le centre de l'huître. (figures 5 et 6).  The user presses the tip (7) at the joint of the two valves, towards the center of the oyster. (Figures 5 and 6).

L'utilisateur effectue ensuite un mouvement de rotation d'un '/2 tour environ dans le sens horaire (flèche 8) puis dans le sens inverse (flèche 9) tout en exerçant une pression sur la pointe (flèche 10) pour l'enfoncer dans la coquille.  The user then makes a rotational movement of about 1/2 turn clockwise (arrow 8) and then in the opposite direction (arrow 9) while exerting pressure on the tip (arrow 10) to push it in in the shell.

L'arrimage de la pointe (7) à la coquille évite tout dérapage de la pièce.  Securing the point (7) to the shell prevents any slippage of the part.

L'utilisateur qui tient l'huître dans son autre main peut faire tourner l'huître en sens contraire pour augmenter l'efficacité du mouvement.  The user holding the oyster in his other hand can turn the oyster in the opposite direction to increase the efficiency of movement.

La bordure de l'huître prise en tenaille par les deux ailettes et la pointe est ébréchée, puis creusée par ce mouvement alterné de rotation, quatre ou cinq rotations suffisent souvent.  The edge of the oyster caught by the two fins and the tip is chipped, then hollowed by this alternating movement of rotation, four or five rotations are often sufficient.

Il n'est pas nécessaire de creuser une cavité de plus de 3 à 4 mm pour pouvoir loger la pointe du couteau dans cette cavité.  It is not necessary to dig a cavity of more than 3 to 4 mm to accommodate the point of the knife in this cavity.

2875115 2 L'utilisateur enfonce ensuite très facilement et en toute sécurité la lame (1) à l'intérieur de l'huître pour y sectionner le muscle et ouvrir l'huître.  2875115 2 The user then very easily and safely drives the blade (1) inside the oyster to cut the muscle and open the oyster.

Si l'utilisateur ne positionne pas la pointe précisément à la jointure des deux valves, il peut néanmoins creuser une petite cavité, ce qui représente un avantage pour les malvoyants.  If the user does not position the tip precisely at the joint of the two valves, it can nevertheless dig a small cavity, which is an advantage for the visually impaired.

Selon des variantes non illustrées, l'extrémité de la pièce a la forme d'une fraise ou d'une meule.  According to non-illustrated variants, the end of the piece has the shape of a cutter or a grinding wheel.

On ne bénéficie pas dans ce cas de l'effet de tenaille décrit précédemment.  In this case, we do not benefit from the pincer effect described above.

Un capuchon amovible protège les pointes en période de non utilisation.  A removable cap protects the tips during periods of non-use.
