Abstract
Description
La présente invention concerne un couteau à ouvrir les huîtres
I1 est connu que les huîtres sont généralement difficiles à ouvrir et qu'il arrive souvent qu'une personne, même experter sé- blesse les mains, aussi bien la main qui tient l'huître que celle qui tient le couteau.The present invention relates to a knife for opening oysters
It is known that oysters are generally difficult to open and that it often happens that a person, even an expert, damages the hands, both the hand which holds the oyster and the one which holds the knife.
Ce risque tient au fait qu'il y a antagonisme entre la main qui tient l'huître et celle qui tient le couteau. L'accident est généralement accasionné par le dérapage du couteau qui n'entre pas entre les deux valves de l'huître. La main qui tient l'huître peut être blessée par le couteau, la main qui tient le couteau peut être blessée par l'huître aux aspérités tranchantes. This risk is due to the fact that there is antagonism between the hand which holds the oyster and that which holds the knife. The accident is generally aggravated by the skidding of the knife which does not enter between the two oyster valves. The hand holding the oyster may be injured by the knife, the hand holding the knife may be injured by the sharp oyster.
Une sorte de bouclier métallique adapté à certains couteaux n'annule pas ce risque. A kind of metal shield adapted to certain knives does not cancel this risk.
Divers systèmes de couteaux existants ou de pinces sont d'une utilisation lente et compliquée et d'une fabrication plus ou moins couteuse. Various systems of existing knives or pliers are slow and complicated to use and more or less expensive to manufacture.
Les systèmes de pinces articulées ne sont pas très efficaces et souvent aussi dangereux que les couteaux . Les systèmes de sciage ou limage des coquilles par des dispositifs de dentures ou d' abrasifs adaptés aux lames ou aux manches des couteaux imposent des mouvements de va et vient du couteau contre l'huître, lents et causes également de dérapages. Articulated clamp systems are not very effective and often as dangerous as knives. The sawing or filing systems of the shells by devices of teeth or abrasives adapted to the blades or the handles of the knives impose back and forth movements of the knife against the oyster, slow and also causes slippage.
Ces inconvénients sont pratiquement annulés par le dispositif de la présente invention qui consiste en un couteau ayant une simple encoche (1) dans la lame (4), le manche (3) ou l'âme du manche (2) permettant de pratiquer, par un mouvement de rotation du poignet, une échancrure sur le bord des valves de l'huître afin de pouvoir introduire facilement la lame du couteau entre les deux valves. These drawbacks are practically eliminated by the device of the present invention which consists of a knife having a simple notch (1) in the blade (4), the handle (3) or the core of the handle (2) making it possible to practice, by a movement of rotation of the wrist, a notch on the edge of the oyster valves in order to be able to easily introduce the blade of the knife between the two valves.
La figure 1 représente uqexemple de l'invention ayant une encoche (l)dans 19 prolongement de la lame formant l'âme du manche. FIG. 1 represents an example of the invention having a notch (1) in the extension of the blade forming the core of the handle.
La figure 2 représente la manière de tenir l'huître (5) à ouvrir et le couteau dans la phase d'utilisation consistant à pratiquer l'échancrure dans les valves. Figure 2 shows the way to hold the oyster (5) to open and the knife in the use phase of practicing the notch in the valves.
Les figures 3 et 4 représentent des exemples non exhaustifs d'encoches (6) (7) pouvant être réalisées soit dans la lame, le manche s'il est métallique ou l'âme du manche, mais pouvant être également réalisées dans des parties métalliques rapportées à la lame ou au manche par soudure ou autre procédé. Figures 3 and 4 show non-exhaustive examples of notches (6) (7) which can be produced either in the blade, the handle if it is metallic or the core of the handle, but which can also be made in metal parts attached to the blade or handle by welding or other process.
Les exemples indiqués de formes d'encoches ne sont pas limitatifs. The examples given of notch shapes are not limiting.
Pour utiliser rationnellement l'objet de l'invention, il convient d'opérer de la façon suivante:
Prendre l'huître dans la main gauche, la charnière de l'huître du côté du poignet. Prendre le couteau dans la main droite et introduire les bords des valves de l'huître dans l'encoche du couteau, à un endroit situé environ aux deux tiers de la longueur de l'huître en partant de sa charnière. C'est proche de cet endroit que se trouve le muscle adducteur de l'huître. Par un mouvement de rotation du poignet droit d'environ un demi tour, échancrer le bord de l'huître.To rationally use the object of the invention, it is necessary to operate in the following manner:
Take the oyster in the left hand, the hinge of the oyster on the wrist side. Take the knife in your right hand and introduce the edges of the oyster valves into the notch of the knife, at a location about two-thirds of the length of the oyster, starting from its hinge. This is where the adductor muscle of the oyster is located. By a rotational movement of the right wrist of about half a turn, notch the edge of the oyster.
A l'endroit de l'échancrure ainsi formée, la jointure des valves étant affaiblie, la ligne de jointure des valves apparait bien clairement, et parfois même un petit trou se trouve être obtenu à cet endroit. On peut alors facilement introduire la lame du couteau entre les deux valves au droit de cette u échancrure pour povoir couper le muscle adducteur et enlever la valve supérieure en la serrant entre le pouce de la main droite et la lame du couteau. At the place of the notch thus formed, the joint of the valves being weakened, the line of joint of the valves appears very clearly, and sometimes even a small hole is found to be obtained at this place. One can then easily introduce the blade of the knife between the two valves to the right of this u notch to be able to cut the adductor muscle and remove the upper valve by squeezing it between the thumb of the right hand and the blade of the knife.
La description ci-dessus concerne un usager droitier, pour un usager gaucher, il suffit d'inverser les tenues de l'huître et du couteau. The description above relates to a right-handed user, for a left-handed user, it is enough to reverse the holdings of the oyster and the knife.
