Abstract

The knife has a locking mechanism of steel with elastic quality, fixed on a handle (2). A plate is fixed perpendicular to the mechanism and is fixed to the sides of the mechanism. A blade (3) pivots around an axis of the handle and placed in the same plane of a longer part of the mechanism. The rotation of blade around the axis exerts a pressure on the mechanism to insert the plate in groove in heel of blade for locking the blade. The blade is unlocked by applying a lateral pressure on the plate to coincide a groove with the heel.

Description

La présente invention concerne un dispositif pour bloquer la lame d'unThe present invention relates to a device for locking the blade of a

couteau pliant en position ouverte et fermée. En effet l'utilisateur d'un couteau pliant désire pouvoir utiliser cet objet en toute sécurité c'est à dire sans que le couteau ne se referme sur ses doigts. A ce désir s'ajoute celui de pouvoir déverrouiller sa  folding knife in open and closed position. Indeed, the user of a folding knife wishes to be able to use this object safely, that is to say without the knife closing on his fingers. To this desire is added that of being able to unlock your

lame de manière simple et rapide.blade quickly and easily.

Le blocage est traditionnellement effectué a l'aide de systèmes complexes avec un nombre élevé de pièces. Certains systèmes plus simples sont peu efficaces.  Locking is traditionally carried out using complex systems with a high number of parts. Some simpler systems are not very effective.

Le dispositif selon l'invention permet de remédier à ces deux inconvénients. Le concept de mon couteau repose donc sur deux principes 10 - un blocage sécurisé de la lame - une seule pièce permettant le verrouillage et le déverrouillage de celle-ci.  The device according to the invention overcomes these two drawbacks. The concept of my knife is therefore based on two principles 10 - a secure blocking of the blade - a single piece allowing the locking and unlocking thereof.

Description du système de fonctionnement.  Description of the operating system.

Plus précisément, le dispositif selon l'invention comporte en effet selon une première caractéristique une tige en acier de section rectangulaire comportant à son extrémité une plaque perpendiculaire à la dite tige.  More specifically, the device according to the invention in fact comprises, according to a first characteristic, a steel rod of rectangular section comprising at its end a plate perpendicular to said rod.

Selon une seconde caractéristique cette plaque est pourvue dans sa partie 20 inférieure de deux encoches verticales symétriques par rapport au centre de cette plaque (figure 1).  According to a second characteristic, this plate is provided in its lower part with two vertical notches symmetrical with respect to the center of this plate (FIG. 1).

Selon une troisième caractéristique la tige d'acier dans sa partie la plus longue est dans le même plan que la lame.  According to a third characteristic, the steel rod in its longest part is in the same plane as the blade.

Selon une quatrième caractéristique c'est l'élasticité de la pièce 1 qui permet a celle-ci d'être déformée et de reprendre sa place au terme des manoeuvres d'ouverture et de fermeture.  According to a fourth characteristic, it is the elasticity of the part 1 which allows it to be deformed and to resume its place at the end of the opening and closing operations.

Dans le but de rendre plus vivante la présentation des caractéristiques de mon invention il me paraît judicieux de la décrire dans le cadre de son fonctionnement. Celui-ci se réfère aux dessins annexés, donnés uniquement à titre d'exemple et dans lesquels: La figure 1 est une vue éclatée en perspective du dispositif de l'invention.  In order to make the presentation of the characteristics of my invention more lively it seems to me wise to describe it in the context of its operation. This refers to the accompanying drawings, given solely by way of example and in which: FIG. 1 is an exploded perspective view of the device of the invention.

La figure 2 est une vue en coupe passant par le centre dudit dispositif dans sa partie la plus longue.  Figure 2 is a sectional view passing through the center of said device in its longest part.

La figure 3 est une vue du mécanisme du dessus, la lame ouverte Suivant un exemple de réalisation, et en se reportant aux dessins annexés un dispositif conforme à l'invention comprend un mécanisme 1 en acier ayant des qualités d'élasticité, fixé au manche 2 a savoir chacune des plaquettes du manche venant se fixer sur un coté du mécanisme enfin la lame 3 pivotant 5 autour d'un axe 4 dans la poignée et placée dans le même plan que la partie le plus longue du mécanisme.  Figure 3 is a view of the mechanism from above, the blade open According to an exemplary embodiment, and with reference to the accompanying drawings, a device according to the invention comprises a mechanism 1 of steel having qualities of elasticity, fixed to the handle 2 namely each of the plates of the handle coming to be fixed on one side of the mechanism finally the blade 3 pivoting 5 around an axis 4 in the handle and placed in the same plane as the longest part of the mechanism.

Le principe est décrit de la manière suivante.  The principle is described as follows.

Lors du pivotement de la lame (3) autour de son axe (4) celle ci exerce une pression sur le mécanisme (1) tenue dans le manche (2) sous l'effet de cette pression cette piece se déplace vers le haut jusqu'à ce que la plaque s'insère dans l'encoche prévue à cet effet dans le talon de la lame au terme de sa rotation.  When the blade (3) pivots about its axis (4), this exerts pressure on the mechanism (1) held in the handle (2) under the effect of this pressure, this piece moves upwards until the plate is inserted into the notch provided for this purpose in the heel of the blade at the end of its rotation.

Pour déverrouiller la lame(3) une pression latérale sur la plaque(l) 15 perpendiculaire au plan déterminé par la lame permet de faire concider une des encoches avec le talon de celle-ci permettant ainsi sa libération.  To unlock the blade (3) lateral pressure on the plate (l) 15 perpendicular to the plane determined by the blade allows one of the notches to reconcile with the heel of the latter thus allowing its release.

Selon des modes particuliers de réalisation: -le levier peut en position fermée maintenir la lame fermée de la même 20 manière qu'elle la maintient ouverte.  According to particular embodiments: the lever can in the closed position keep the blade closed in the same way as it keeps it open.

-le levier peut être constitué par une partie de la poignée.  -the lever can be constituted by a part of the handle.

-la lame peut recevoir plusieurs encoches permettant de multiples positions.  -the blade can receive several notches allowing multiple positions.

Les dessins annexés illustrent l'invention: En référence à ces dessins, le dispositif est composé d'une pièce (1)dont l'extrémité est munie d'une plaque perpendiculaire munie de deux encoches.  The accompanying drawings illustrate the invention: With reference to these drawings, the device is made up of a part (1) the end of which is provided with a perpendicular plate provided with two notches.

Le dispositif est fixé sur le manche (2), La lame (3) est munie au niveau du talon 30 d'un évidement permettant la réception de la plaque du dispositif (1). Lors de la rotation de la lame (3) autour de son axe(4) celle-ci pousse le dispositif (1) vers le haut jusqu'à ce qu'il est concidence entre l'évidement de la lame et la plaque.  The device is fixed on the handle (2), The blade (3) is provided at the heel 30 with a recess allowing the reception of the device plate (1). When the blade (3) rotates about its axis (4), the latter pushes the device (1) upwards until it is between the recess of the blade and the plate.

La pression latérale exercée sur l'un des coté du dispositif(l) au niveau de la plaque permet de faire correspondre les encoches avec la lame(3) permettant 35 ainsi sa libération.  The lateral pressure exerted on one side of the device (1) at the level of the plate makes it possible to match the notches with the blade (3) thus allowing it to be released.

On a donc réalisé suivant l'invention un dispositif permettant le blocage d'une lame ce dispositif etant composé d'une seule piece.  A device has therefore been produced according to the invention allowing the blocking of a blade, this device being composed of a single piece.

Bien entendu l'invention n'est nullement limitée au mode de réalisation décrit et 40 présenté qui n'a été donné qu'a titre d'exemple. Ainsi les matériaux entrant en jeu dans la fabrication des trois éléments peuvent être quelconques de même que leur longueur et leur largeur.  Of course, the invention is in no way limited to the embodiment described and presented, which has been given only by way of example. Thus the materials involved in the manufacture of the three elements can be any as well as their length and their width.

C'est à dire que l'invention comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci sont exécutées suivant son esprit et mises en oeuvre dans le cadre des revendications qui suivent 15 20 25 30 35  That is to say that the invention includes all the technical equivalents of the means described as well as their combinations if these are carried out according to the spirit and implemented within the scope of the claims which follow
