Description

La présente invention concerne couteau de poche à lame verrouillable comprenant un moyen de déverrouillage à bouton-poussoir.The present invention relates to a pocket knife with a lockable blade comprising a push button unlocking means.

Plusieurs couteaux de poche de types connus permettent de verrouiller la lame en position sortie. L'utilisation du couteau est ainsi plus aisée et plus sûre. Un premier moyen de verrouillage de type connu consiste en une lamelle latérale pivotante comprenant une portion avant servant de moyen de blocage et une portion arrière servant de bras de levier afin de faire s'approcher ou s'éloigner la portion avant. Pour déverrouiller la lame du couteau, l'utilisateur appuie sur la portion arrière de la lamelle, ce qui désengage la portion avant et libère la lame. L'effort appliqué par l'utilisateur est concentré sur une surface très mince qui a tendance à pénétrer dans le peau, rendant l'utilisation incommodante. Un tel couteau comprend une encoche latérale permettant d'avoir accès à la portion arrière de la lamelle. Cette encoche empêche qu'on puisse disposer d'autres outils sur cette portion du couteau. De plus, la lamelle utilisée est très longue et occupe une place importante dans le boîtier du manche du couteau. Il existe aussi un moyen de verrouillage plus compact, permettant de loger des outils sur une portion du manche. Un poussoir de déverrouillage latéral disposé à la portion avant du manche permet d'éloigner la lamelle afin de libérer la lame du couteau. Pour fonctionner, le poussoir doit être proéminent du bord latéral du manche et offrir un bras de levier suffisamment long pour minimiser l'effort nécessaire pour le déverrouillage. Le point d'appui est donc relativement éloigné du manche. Cette conformation présente des risques d'égratignures pour l'utilisateur ou encore des risques d'abîmer les poches des vêtements. De plus, le poussoir latéral nécessite une certaine place à la partie avant du manche, où un autre outil ne peut donc pas être disposé. Un autre type de couteau de type connu comprend une lamelle latérale de verrouillage dont la partie avant peut être déplacée parallèlement à l'axe de pivotement de la lame. En position de repos, la lamelle est en contact avec la lame et la bloque; lorsque l'utilisateur appuie sur la lamelle, la lame est libérée et peut être rétractée. Ce type de couteau nécessite également une encoche latérale afin de donner accès à la lamelle. Il est donc encore une fois impossible d'optimiser la disposition des outils dans le cas d'un couteau multifonctions.Several pocket knives of known types make it possible to lock the blade in the extended position. The use of the knife is thus easier and safer. A first locking means of known type consists of a pivoting lateral strip comprising a front portion serving as locking means and a rear portion serving as a lever arm in order to bring the front portion closer or further away. To unlock the knife blade, the user presses on the rear portion of the coverslip, which disengages the front portion and releases the blade. The effort applied by the user is concentrated on a very thin surface which tends to penetrate the skin, making use inconvenient. Such a knife includes a lateral notch allowing access to the rear portion of the strip. This notch prevents other tools from being available on this portion of the knife. In addition, the strip used is very long and occupies an important place in the case of the knife handle. There is also a more compact locking means, allowing tools to be accommodated on a portion of the handle. A lateral unlocking pusher disposed at the front portion of the handle allows the blade to be moved away in order to free the blade from the knife. To operate, the pusher must be prominent from the side edge of the handle and offer a lever arm long enough to minimize the effort required to unlock. The fulcrum is therefore relatively far from the handle. This conformation presents risks of scratches for the user or risks of damaging the pockets of clothing. In addition, the lateral pusher requires a certain space at the front part of the handle, where another tool cannot therefore be placed. Another type of knife of known type comprises a lateral locking strip, the front part of which can be moved parallel to the pivot axis of the blade. In the rest position, the strip is in contact with the blade and blocks it; when the user presses on the slat, the blade is released and can be retracted. This type of knife also requires a side notch to give access to the coverslip. It is therefore again impossible to optimize the arrangement of the tools in the case of a multifunction knife.

Le but principal de la présente invention est de proposer un couteau de poche à lame verrouillable comprenant un moyen de verrouillage permettant d'éviter ces inconvénients. Ce but est atteint grâce aux moyens revendiqués.The main object of the present invention is to provide a pocket knife with a lockable blade comprising a locking means making it possible to avoid these drawbacks. This goal is achieved by the means claimed.

Le couteau de poche à lame déverrouillable selon la présente invention comprend un moyen de déverrouillage offrant l'avantage d'être très compact. Aucun élément (exception faite de la lamelle de verrouillage) n'est disposé latéralement le long du manche du couteau. Ceci est particulièrement avantageux pour un couteau multi-fonctions, qui dispose ainsi d'un maximum de possibilités pour répartir les différents outils. Le poussoir très légèrement proéminent est discret et facile à utiliser et ne présente pas de risque d'égratignures pour l'utilisateur ou encore de risque d'abîmer les poches des vêtements.The pocket knife with an unlockable blade according to the present invention comprises an unlocking means offering the advantage of being very compact. No element (except for the locking strip) is arranged laterally along the handle of the knife. This is particularly advantageous for a multi-function knife, which thus has maximum possibilities for distributing the different tools. The very slightly prominent button is discreet and easy to use and presents no risk of scratches for the user or risk of damaging the pockets of clothing.

L'invention sera maintenant décrite à l'aide de la description qui suit et du dessin qui l'illustre, à titre d'exemple, et dans lequel:

  • la fig. 1 représente une coupe longitudinale de la portion centrale d'un couteau à lame verrouillable avec moyen de déverrouillage selon la présente invention, en 1a avec lame verrouillée, en 1b avec lame déverrouillée;
  • la fig. 2 représente une coupe transversale (selon la ligne II-II de la fig. 1a) de la portion centrale d'un couteau à lame verrouillable avec moyen de déverrouillage selon la présente invention, en 2a avec lame verrouillée, en 2b avec lame déverrouillée;
  • la fig. 3 représente une première variante du moyen de déverrouillage selon l'invention;
  • la fig. 4 représente une deuxième variante du moyen de déverrouillage selon l'invention.
The invention will now be described with the aid of the following description and the drawing which illustrates it, by way of example, and in which:
  • fig. 1 shows a longitudinal section of the central portion of a knife with a lockable blade with unlocking means according to the present invention, in 1a with locked blade, in 1b with unlocked blade;
  • fig. 2 shows a cross section (along line II-II of FIG. 1a) of the central portion of a knife with a lockable blade with unlocking means according to the present invention, in 2a with a locked blade, in 2b with an unlocked blade;
  • fig. 3 shows a first variant of the unlocking means according to the invention;
  • fig. 4 shows a second variant of the unlocking means according to the invention.

Les fig. 1a et 2a illustrent un couteau à lame verrouillable, avec moyen de déverrouillage selon la présente invention, dont la lame est verrouillée en position sortie. Le couteau comprend une lame 4, avec une portion coupante, dont le côté plat définit un plan, appelé ici "plan de la lame". La lame pivote autour d'un pivot 5, sensiblement perpendiculaire au plan de la lame et situé à la jonction entre la lame et le manche. Il comprend également une lamelle de verrouillage 2 à ressort de type connu, disposée latéralement le long du manche du couteau dans un plan sensiblement parallèle au plan de la lame. L'embout 2a de la lamelle de verrouillage 2 coopère avec un point d'ancrage 6 de la lame 4, lorsque cette dernière est en position sortie; la lame est alors verrouillée dans cette position.Figs. 1a and 2a illustrate a knife with a lockable blade, with unlocking means according to the present invention, the blade of which is locked in the extended position. The knife comprises a blade 4, with a cutting portion, the flat side of which defines a plane, called here "plane of the blade". The blade pivots around a pivot 5, substantially perpendicular to the plane of the blade and located at the junction between the blade and the handle. It also comprises a locking strip 2 with spring of known type, arranged laterally along the handle of the knife in a plane substantially parallel to the plane of the blade. The tip 2a of the locking strip 2 cooperates with an anchoring point 6 of the blade 4, when the latter is in the extended position; the blade is then locked in this position.

Il comprend également un moyen de déverrouillage 1, muni d'un bouton-poussoir 10 (fig. 2), d'une lame flexible 11, avantageusement en deux parties réunies par un pivot 11a. Le bouton-poussoir 10 est disposé dans une des faces latérales 8 du couteau et peut être déplacé selon un axe sensiblement perpendiculaire au plan de la lame. La lame flexible 11 est disposée sous le bouton-poussoir 10, appuyant contre la face inférieure de celui-ci. Une première extrémité de la lame flexible repose contre un point d'appui 7 de la lamelle de verrouillage 2. L'autre extrémité est maintenue fixe dans une encoche 3a pratiquée dans la paroi intermédiaire 3 du manche. Ainsi, lorsque l'utilisateur appuie sur le bouton-poussoir 10, grâce à un déplacement de ce dernier vers l'intérieur du manche selon un axe sensiblement perpendiculaire au plan de la lame 4, la lame flexible tend à s'écarter; l'extrémité libre de celle-ci se déplace suivant un plan sensiblement parallèle à celui de la lame 4 et agit contre la face d'appui 7 pour déplacer la lamelle 2 et libérer l'embout 2a du point d'ancrage 6. La lame 4 est alors libre de pivoter autour du pivot 5.It also includes an unlocking means 1, provided with a push button 10 (fig. 2), with a flexible blade 11, advantageously in two parts joined by a pivot 11a. The push button 10 is arranged in one of the lateral faces 8 of the knife and can be moved along a substantially perpendicular axis in the plane of the blade. The flexible blade 11 is arranged under the push-button 10, pressing against the underside of the latter. A first end of the flexible blade rests against a fulcrum 7 of the locking strip 2. The other end is held fixed in a notch 3a formed in the intermediate wall 3 of the handle. Thus, when the user presses the push-button 10, by virtue of a displacement of the latter towards the inside of the handle along an axis substantially perpendicular to the plane of the blade 4, the flexible blade tends to move apart; the free end of the latter moves along a plane substantially parallel to that of the blade 4 and acts against the bearing face 7 to move the strip 2 and release the end piece 2a from the anchoring point 6. The blade 4 is then free to pivot around the pivot 5.

Les flèches des fig. 2a et 2b illustrent les forces dominantes:
   En 2a la lame de verrouillage repousse la lame flexible 11 qui maintient le bouton-poussoir en position relevée;
   en 2b, lorsque l'utilisateur appuie sur le bouton-poussoir, la lamelle 2 est écartée.The arrows in fig. 2a and 2b illustrate the dominant forces:
In 2a the locking blade pushes the flexible blade 11 which keeps the push-button in the raised position;
in 2b, when the user presses the push-button, the strip 2 is moved aside.

Selon une variante d'exécution, le bouton-poussoir 10 peut comprendre une rainure 10a, pratiquée au niveau de sa face inférieure, afin que la lame flexible 11 puisse s'imbriquer partiellement dans le bouton-poussoir.According to an alternative embodiment, the push button 10 may include a groove 10a, formed at its lower face, so that the flexible blade 11 can partially overlap in the push button.

Les fig. 3 et 4 illustrent divers exemples de variantes du moyen de déverrouillage 1 selon la présente invention. A la fig. 3, un poussoir intermédiaire 12 comprend un plan incliné 13 en contact avec le poussoir 10, la portion opposée étant en contact avec le point d'appui 7 de la lamelle 2. Lorsque l'utilisateur appuie sur le bouton-poussoir, la partie inférieure de celui-ci exerce une force de répulsion tendant à faire déplacer le poussoir 12 suivant un plan sensiblement parallèle à celui de la lame 4, agissant contre le point d'appui 7 et écartant ainsi la lamelle 2 de façon à libérer l'embout 2a du point d'ancrage 6.Figs. 3 and 4 illustrate various examples of variants of the unlocking means 1 according to the present invention. In fig. 3, an intermediate pusher 12 comprises an inclined plane 13 in contact with the pusher 10, the opposite portion being in contact with the fulcrum 7 of the strip 2. When the user presses the push button, the lower part of this exerts a repulsive force tending to cause the pusher 12 to move in a plane substantially parallel to that of the blade 4, acting against the fulcrum 7 and thus spreading the strip 2 so as to release the end piece 2a from the anchor point 6.

Selon une variante (non montrée), le plan incliné est disposé à la partie inférieure du bouton-poussoir 10. On pourrait également utiliser simultanément ces deux plans inclinés.According to a variant (not shown), the inclined plane is arranged at the lower part of the push button 10. It is also possible to use these two inclined planes simultaneously.

La fig. 4 illustre une variante où le plan incliné 13 est disposé en bordure de la lamelle 2, à l'interface entre la lamelle et le bouton-poussoir 10. Le fonctionnement est alors similaire à la variante montrée à la fig. 3.Fig. 4 illustrates a variant where the inclined plane 13 is arranged at the edge of the strip 2, at the interface between the strip and the push button 10. The operation is then similar to the variant shown in FIG. 3.
