Abstract

The tool is shaped like pincers and is made in stainless steel. It is approximately 20cm long and its overall width, when it is closed, is approximately 5cm and is about 0.8cm thick. The axial length of the active part (1) is about 60mm. The angle of the cutting blades (3) is about 30 deg on top and the bottom of the blades is flat. The closed blades (4) are at an angle of about 25 deg on either side of the axis of symmetry and the width of their points is at least 35mm.

Description

DESCRITION
La présente invention concerne un outil pour ouvrir facilement et sans danger les hultres en particulier et tous les coquillages bivalves en général.DESCRIPTION
The present invention relates to a tool for easily and safely opening oysters in particular and all bivalve shells in general.

L'ouverture des huîtres est traditionnellement effectuée à l'aide d'un couteau à hultre, ce qui traumatise l'utilisateur, par le risque de blessure et par l'effort à foumir. The opening of oysters is traditionally carried out using an oyster knife, which traumatizes the user, by the risk of injury and by the effort to provide.

Certains ont mis au point des systèmes d'ouverture, tel que: le fil d'acier pour sectionner le muscle adducteur, ou la capsule d'ouverture rapide. Mais cela implique une préparation des coquillages, donc un prix accru, et le risque connu d'une mortalité importante de l'espèce. Some have developed opening systems, such as: steel wire to cut the adductor muscle, or the rapid opening capsule. But this implies a preparation of shellfish, therefore an increased price, and the known risk of significant mortality of the species.

L'outil selon l'invention permet de remédier à ces inconvénients. II ne nécessite pas de préparation des coquillages. The tool according to the invention overcomes these drawbacks. It does not require preparation of shellfish.

II se compose, selon une première caractéristique, d'une pince spéciale profilée en acier inoxydable ou nickele,dont la fonction est de sectionner la charnière du coquillage, tout en
Soulevant l'arrière de la valve supérieure.It consists, according to a first characteristic, of a special profiled pliers in stainless steel or nickele, the function of which is to cut the hinge of the shell, while
Lifting the back of the upper valve.

Cette action a pour effet de laisser apparaitre un joint droit et gauche suffisant entre la valve supérieure et inférieure, pour permettre l'introduction aisée d'une lame de couteau, ou autre, nécessaire éventuellement à l'ablation du muscle adducteur. This action has the effect of revealing a sufficient right and left joint between the upper and lower valve, to allow easy introduction of a knife blade, or other, possibly necessary for the ablation of the adductor muscle.

II convient de souligner l'importance de: - La longueur axiale de la partie active de l'outil (1 ) par rapport à l'axe de rotation (2): 50 mm à 60 mm. Pour éviter la longueur du crochet du coquillage - L' angle d'attaque (3) des lames de coupes: 28 à 32 sur le dessus et plat dessous, pour éviter le dépôt d'écailles. The importance of: - The axial length of the active part of the tool (1) relative to the axis of rotation (2): 50 mm to 60 mm. To avoid the length of the shell hook - The angle of attack (3) of the cutting blades: 28 to 32 on the top and flat below, to avoid the deposit of scales.

- Du pincement des tranchants des lames fermées (4): 25 à 40 "/ axe, pour une prise facile.- Pinching the edges of the closed blades (4): 25 to 40 "/ axis, for easy grip.

- de la largeur des pointes de la partie active (5), ouverte: 35 mm minimum, pour une action possible sur des coquillages de gros calibre.- the width of the tips of the active part (5), open: 35 mm minimum, for possible action on large-sized shells.

Selon les modes particuliers de réalisation:
Le profil et l'angle d'attaque (3) des lames de coupe pourra être droit ou concave. Le Design de l'outil variable; en particulier l'ovale de la partie active ( 1 ), fonction de la longueur totale.According to the particular embodiments:
The profile and angle of attack (3) of the cutting blades can be straight or concave. The Design of the variable tool; in particular the oval of the active part (1), a function of the total length.

Les dessins annexés illustrent l'invention:
La figure 1 représente le plan de dessus de l'invention.The accompanying drawings illustrate the invention:

A titre d'exemple non limitatif, L'outil aura les dimensions suivantes: - Longueur 15 à 20 Cm. Largeur hors tout, fermé: 5 Cm environ. Epaisseur: 4,5 à 8 mm. By way of nonlimiting example, the tool will have the following dimensions: - Length 15 to 20 cm. Overall width, closed: about 5 cm. Thickness: 4.5 to 8 mm.
