Description
DISPOSITIF DE PROTECTION DES DOIGTS SUR UN COUTEAU A LAME FERMANTE
L'invention appartient au domaine de la coutellerie à lame fermante et elle a pour objet un dispositif de protection des doigts lis à vis de la partie affûtée de cette lame.FINGER PROTECTION DEVICE ON A CLOSING BLADE KNIFE
The invention belongs to the field of cutlery with a closing blade and it relates to a device for protecting the fingers read against the sharpened part of this blade.
On connait des couteaux dont la partie affûtée de la lame voire même la partie épaisse, ne sont pas accessibles par les doigts et ce, notamment lors d'une poussée violente exercée ers la pointe de cette lame. Knives are known whose sharpened part of the blade or even the thick part, are not accessible by fingers and this, especially during a violent push exerted ers the tip of this blade.
Une telle inacessibilité de la partie large mais surtout de la partie tranchante de cette lame a pl être garantie dans le domaine de la coutellerie non pliante par une garde installée sur le porte lame ou manche de cette lame. Such inaccessibility of the wide part but especially of the cutting part of this blade has to be guaranteed in the field of non-folding cutlery by a guard installed on the blade holder or handle of this blade.
C'est ainsi que les poignards permettent d'effectuer, voire d'asséner de violents coups vers l'avant de leur lame sans risquer de blesser la main qui les porte. This is how daggers allow you to make, or even strike, violent blows towards the front of your blade without risking injury to the hand carrying them.
Un tel dispositif de garde, solidaire du manche de la lame, ne saurait être adapté à la coutellerie à lame fermante dont la vocation, lorsqu'elle ne sen pas à trancher, est de demeurer de la façon la plus discrète a confortable qui soit dans la poche. Such a guard device, integral with the handle of the blade, cannot be adapted to cutlery with a closing blade, the vocation of which, when it does not cut, is to remain in the most discreet and comfortable way possible. the pocket.
II a donc été proposé d'adapter sur certains couteaux à lame fermante, une garde qui ne soit solidaire ni du manche, ni de la lame. Une telle garde vient se positionner perpendiculairement au manche et à la lame lorsque le couteau est ouvert et 'nt se ranger le long du manche lorsque celuici est fermé. It has therefore been proposed to adapt, on certain knives with a closing blade, a guard which is neither integral with the handle nor with the blade. Such a guard is positioned perpendicularly to the handle and to the blade when the knife is open and 'nt to be stored along the handle when it is closed.
Le dispositif permettant un tel bascuiement de la garde est cependant délicat et onéreux à fabriquer. La complexité d'un tel dispositif le rend en outre délicat et difficile à nettoyer. The device allowing such a tilting of the guard is however delicate and expensive to manufacture. The complexity of such a device also makes it delicate and difficult to clean.
Il importait donc de mettre au point un couteau à lame fermante dont le dispositif de garde de la partie tranchante de la lame puisse s'intégrer complètement au volume externe délimité par le manche lorsque cette lame se trouve repliée d enfermée dans ce manche et qui soit à la fois efficace, simple à fabriquer et aussi à nettoyer. It was therefore important to develop a knife with a closing blade whose guard for the sharp part of the blade can be completely integrated into the external volume delimited by the handle when this blade is folded up enclosed in this handle and which is both efficient, simple to manufacture and also to clean.
J'ai trouvé qu'un tel couteau à lame fermante(5), componant un manche pounu d'une cavité(3) destinée à accueillir cette lame, pouvait ittre caractérise par le fait que la lame fermantc( 1) compote de façon solidaire du côté tranchant de cene lame et près de son axe de rotation, un ergot faisant office de garde(2) et que le manche de ce couteau comporte un évidement(4) pouvant englober cet ergot lorsque la lame est refermée. I have found that such a knife with a closing blade (5), comprising a handle provided with a cavity (3) intended to receive this blade, could be characterized by the fact that the closing blade (1) compote in a solid manner on the cutting side of this blade and near its axis of rotation, a lug acting as a guard (2) and that the handle of this knife has a recess (4) which can include this lug when the blade is closed.
Un tel couteau procure à la fois confon et sécurité pour un prix modique. Such a knife provides both comfort and security for a low price.
Dans cette description du couteau objet de l'invention, les chiffres entre parenthèses se réferent aux figures de la planche 1/1 où
-la figurel représente une vue de dos d'un couteau selon l'invention
-la figure2 représente une vue de face d'un couteau selon l'invention
-la figure3 représente le couteau selon l'invention en position ouverte
-la figure4 représente le couteau selon l'invention en position semiouvefle
-la figure5 représente le couteau selon l'invention en position fermée
Au vu de la description qui précédé et des figures qui sont jointes, on aura compris que par une rotation de 1800 autour de son axe(O), la lame fermante(1) et son ergot solidaire(2) s'engagent respectivernent dans les cavités(3) et (4) pounues dans le manche (5)de faucon à y disparaitre en qua5i-totalité. In this description of the knife which is the subject of the invention, the figures in parentheses refer to the figures in plate 1/1 where
the figurel represents a back view of a knife according to the invention
FIG. 2 represents a front view of a knife according to the invention
FIG. 3 represents the knife according to the invention in the open position
FIG. 4 represents the knife according to the invention in the semi-open position
FIG. 5 represents the knife according to the invention in the closed position
In view of the foregoing description and the attached figures, it will be understood that by a rotation of 1800 around its axis (O), the closing blade (1) and its integral lug (2) engage respectively in the cavities (3) and (4) pounues in the handle (5) of falcon to disappear there in qua5i-totality.
De même, qu'une partie de la lame ne s'engage généralement pas complètement dans Ie manche afin de faciliter l'ouverture du couteau, I'ergot peut aussi légèrement dépasser du manche afin de procurer une protection plus grande et aussi de faciliter l'ouverture du couteau en le pressant. Likewise, as a part of the blade does not generally fully engage in the handle in order to facilitate the opening of the knife, the lug may also slightly protrude from the handle in order to provide greater protection and also to facilitate the opening of the knife by pressing it.
Le couteau selon l'invention est donc aussi caractérisé par le fait que l'ergot(2) est d'une longueur telle que l'englobement de cet ergot par l'évidement(+) n'est que partiel dans le sens de cette longueur. The knife according to the invention is therefore also characterized by the fact that the lug (2) is of a length such that the inclusion of this lug by the recess (+) is only partial in the direction of this length.
C'est cette configuration qui est représentée sur les figures de la planche 1/1
L'ergot peut bien entendu, entre usiné en meme temps que la lame dans la mtme pièce de métal, mais il peut aussi ttrc apporté sur ceile-ci par soudure ou brasure.It is this configuration which is represented in the figures of plate 1/1
The lug can, of course, between being machined at the same time as the blade in the same piece of metal, but it can also be brought to the latter by welding or soldering.
Si le manche du couteau est réalisé en un seul matériau, on put par simple perçage de ce manche, réaliser le trou borgne ou le perçage complet du manche de manière à réaliser la cavnt qui fera disparaitre l'ergot lorsque la lame est refermée. If the handle of the knife is made of a single material, we could by simply drilling this handle, make the blind hole or the complete drilling of the handle so as to make the cavnt which will make the lug disappear when the blade is closed.
Si ce manche comporte une àme d'acier destinée à le renforcer, il conviendra de donner à cette âme une forme telle qu'elle présente un oeil qui puisse accueillir cet ergot et l'englober lorsque la lame est refermée.If this handle has a steel core intended to strengthen it, it will be necessary to give this soul a shape such that it has an eye which can accommodate this lug and encompass it when the blade is closed.
Dans tous les cas cependant, l'ergot présentera une facc prochc du manche, lorsque la lame est dépliée, qui soit suffisamment large pour que la pression exercée par des doigts qui glissent sur le manche et viennent buter sur l'ergot soit insuffisante pour provoquer une quelconque blessure. In all cases, however, the lug will present a near facc of the handle, when the blade is unfolded, which is wide enough that the pressure exerted by fingers which slide on the handle and come up against the lug is insufficient to cause any injury.
La largeur de cette face sera avantageusement, approximativement égale ou supérieure à celle dc la paruc large de b lame. The width of this face will advantageously be approximately equal to or greater than that of the wide blade blade.
La description et surtout les dessins y relatifs ne prétendent pas représenter toutes les fonnes de réalisation de l'invention. ns figurent à titre illustratif et ne sauraicnt en aucun cas réduire l'invention aux seuls couteaux à lame fcrmante présentant les caractéristiques décrites et illustrées. The description and especially the drawings relating thereto do not claim to represent all of the embodiments of the invention. They are given by way of illustration and will in no way reduce the invention to only knives with a sharp blade having the characteristics described and illustrated.
