Description

DOMAINE TECHNIQUETECHNICAL AREA

La présente invention se rapporte au secteur technique des instruments de coutelleries et notamment au secteur technique des couteaux à lame repliable. L'invention concerne plus particulièrement un système de verrouillage de lame en position dépliée pour couteau à lame repliable.The present invention relates to the technical sector of cutlery instruments and in particular to the technical sector of folding blade knives. The invention more particularly relates to a blade locking system in the unfolded position for folding blade knife.

L'invention trouve notamment une application avantageuse dans le domaine des couteaux du type dit « outdoor » (en terminologie anglaise), couteaux de survie et couteaux tactiques.The invention finds an advantageous application in the field of knives of the so-called "outdoor" type (in English terminology), survival knives and tactical knives.

ART ANTERIEURPRIOR ART

Dans l'état de la technique actuel, il existe plusieurs solutions permettant de verrouiller la lame, en position dépliée, d'un couteau à lame repliable.In the current state of the art, there are several solutions for locking the blade, in the unfolded position, of a folding blade knife.

Une première technique consiste par exemple en un système de verrouillage de lame par friction. C'est uniquement le frottement de la lame contre les platines de la partie formant manche qui verrouille la lame du couteau en position dépliée. Sur certains modèles de couteaux, le pivot de la lame est réalisé par une vis, il est alors possible de resserrer l'axe pour ajuster la friction désirée. Cette technique ne donne pas une entière satisfaction, le verrouillage de la lame n'est pas optimal.A first technique consists for example of a friction blade locking system. It is only the friction of the blade against the plates of the handle portion that locks the knife blade in the unfolded position. On some models of knives, the pivot of the blade is realized by a screw, it is then possible to tighten the axis to adjust the desired friction. This technique does not give complete satisfaction, the locking of the blade is not optimal.

Un seconde technique consiste en ce que la partie supérieure du talon de la lame est crochetée par une tige métallique insérée entre les platines, dans la partie supérieure. La lame est ainsi complètement verrouillée. Pour la libérer, il faut actionner un ressort, placé sur le dos ou en arrière du manche, qui libère la tige de blocage. Cette technique donne une entière satisfaction en termes de verrouillage mais comprend cependant des risques de déverrouillages accidentels lorsqu'il est nécessaire de maintenir fermement le manche du couteau.A second technique consists in that the upper part of the heel of the blade is hooked by a metal rod inserted between the plates, in the upper part. The blade is thus completely locked. To release it, it is necessary to actuate a spring, placed on the back or behind the handle, which frees the blocking rod. This technique gives complete satisfaction in terms of locking but also includes the risk of accidental unlocking when it is necessary to firmly hold the handle of the knife.

Une troisième technique est divulguée par le documentA third technique is disclosed by the document FR 2 782 287FR 2 782 287 qui divulgue un système de verrouillage de lame conforme au préambule de la revendication 1.which discloses a blade lock system according to the preamble of claim 1.

Il existe de nombreux systèmes de verrouillage de lame en position dépliée pour couteaux à lame repliable, chacun avec ses avantages et inconvénients et chacun avec un degré de verrouillage plus ou moins important.There are many blade locking systems in the unfolded position for folding blade knives, each with its advantages and disadvantages and each with a degree of locking more or less important.

EXPOSE DETAILLE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

Les figures 1 à 13 représentent une forme de réalisation préférée du système de verrouillage (1) de lame (4) selon l'invention, monté sur un couteau (2) à lame repliable, comprenant une partie formant manche (3) permettant à un utilisateur de saisir le couteau (2), et une lame (4) montée pivotante par rapport à cette partie formant manche (3). La lame (4) est apte à pivoter pour adopter soit une première position repliée de rangement, dans laquelle elle se trouve partiellement cachée dans ladite partie formant manche (3), soit une deuxième position dépliée d'utilisation.The Figures 1 to 13 represent a preferred embodiment of the locking system (1) blade (4) according to the invention, mounted on a knife (2) with foldable blade, comprising a handle portion (3) allowing a user to grasp the knife (2), and a blade (4) pivotally mounted with respect to this handle portion (3). The blade (4) is pivotable to adopt either a first folded storage position, in which it is partially hidden in said handle portion (3), or a second unfolded position of use.

La partie formant manche (3) est constituée par une pièce formant une âme centrale (5), recouverte par deux platines (6) de formes ergonomiques pour la main d'un utilisateur. Les deux platines (6) sont de préférences identiques. La lame (4) est montée pivotante autour d'un axe (7) traversant le talon (4a) de ladite lame (4) et la partie d'extrémité des deux platines (6). La lame (4) est donc apte à adopter deux positions, une première position repliée de rangement, dans laquelle la lame (4) est en butée contre la partie formant âme centrale (5) et partiellement cachée dans la partie formant manche (3), entre les deux platines (6), et une deuxième position dépliée d'utilisation, dans laquelle la lame (4) est complètement dépliée, en alignement avec la partie formant manche (3) et en butée contre la partie formant âme centrale (5).The handle portion (3) is constituted by a piece forming a central core (5), covered by two plates (6) of ergonomic shapes for the hand of a user. The two plates (6) are preferably identical. The blade (4) is pivotally mounted around an axis (7) passing through the heel (4a) of said blade (4) and the end portion of the two plates (6). The blade (4) is therefore able to adopt two positions, a first folded storage position, in which the blade (4) abuts against the central core portion (5) and partially concealed in the handle portion (3) between the two plates (6) and a second unfolded position of use, in which the blade (4) is completely unfolded, in alignment with the handle portion (3) and abutting against the central core portion (5). ).

Le système de verrouillage (1) de lame (4) selon l'invention comprend des premiers moyens de verrouillage (8) se présentant sous la forme d'une lame souple (8), agencée sur le dessus du couteau (2), en contact avec les tranches des deux platines (6) et fixée sur l'âme centrale (5). Cette lame souple (8) est apte à adopter deux positions, une première position de verrouillage de la lame (4) en position dépliée et une deuxième position de non verrouillage de ladite lame (4). A cet effet, la lame souple (8) comprend à son extrémité en regard de la lame (4), un évidement (8a) apte à coopérer avec un doigt (9) présent sur la partie supérieure du talon (4a) de la lame (4), en regard de la lame souple (8). Ainsi, lors du pivotement de la lame (4), lorsque celle-ci arrive en butée contre la partie formant âme centrale (5), le doigt (9) présent sur la partie supérieure du talon (4a) de la lame (4) pénètre dans l'évidement (8a) formé dans la lame souple (8). Ceci a pour effet de crocheter la lame souple (8) sur le talon (4a) de la lame (4) du couteau (2) et de verrouiller ladite lame (4) en position dépliée.The locking system (1) blade (4) according to the invention comprises first locking means (8) in the form of a flexible blade (8), arranged on the top of the knife (2), in contact with the slices of the two plates (6) and fixed on the central core (5). This flexible blade (8) is adapted to adopt two positions, a first locking position of the blade (4) in the unfolded position and a second non-locking position of said blade (4). For this purpose, the flexible blade (8) comprises at its end facing the blade (4), a recess (8a) adapted to cooperate with a finger (9) present on the upper portion of the heel (4a) of the blade (4), facing the flexible blade (8). Thus, during the pivoting of the blade (4), when it is in abutment against the central core portion (5), the finger (9) present on the upper portion of the heel (4a) of the blade (4) penetrates into the recess (8a) formed in the flexible blade (8). This has the effect of picking the flexible blade (8) on the heel (4a) of the blade (4) of the knife (2) and to lock said blade (4) in the unfolded position.

Le système de verrouillage (1) de lame (4) selon l'invention comprend en outre des deuxièmes moyens de verrouillage (10) aptes à adopter deux positions, une première position de verrouillage desdits premiers moyens de verrouillage (8) dans la première position de verrouillage de la lame (4) en position dépliée, et une deuxième position de non verrouillage, dans laquelle lesdits deuxièmes moyens de verrouillage (10) forcent lesdits premiers moyens de verrouillage (8) à adopter la deuxième position de non verrouillage de la lame (4). A cet effet, lesdits deuxièmes moyens de verrouillage (10) se présentent sous la forme d'une première pièce (10) montée pivotante autour d'un axe (10a) traversant à la fois ladite première pièce (10) et la partie d'extrémité des deux platines (6) de la partie formant manche (3). Ladite première pièce (10) comprend une partie formant crochet (10b) réalisée notamment par le ménagement d'une encoche (10c) dans la matière de ladite première pièce (10). Cette encoche (10c) est apte à coopérer, après pivotement de ladite première pièce (10) jusqu'à une première position de verrouillage, avec un ergot (8b) présent sur la partie latérale de la lame souple (8) pour verrouiller celle-ci en position de verrouillage de la lame (4) du couteau (2) en position dépliée. Cette première pièce (10) comprend également une partie formant excentrique (10d) et apte, après pivotement de ladite première pièce (10) dans le sens inverse jusqu'à une deuxième position de non verrouillage, à soulever ladite lame souple (8) et désengager le doigt (9) de la lame (4) du couteau (2) de l'évidement (8a) de la lame souple (8), afin de forcer ladite lame souple (8) à adopter une deuxième position de non verrouillage de la lame (4) du couteau (2). Enfin, ladite première pièce (10) comprend, une partie, opposée à l'encoche, formant levier (10e) et destinée à permettre à l'utilisateur de manipuler ladite première pièce (10) et de la faire passer de la première à la deuxième position.The locking system (1) blade (4) according to the invention further comprises second locking means (10) adapted to adopt two positions, a first locking position of said first locking means (8) in the first position locking the blade (4) in an unfolded position, and a second non-locking position, wherein said second locking means (10) causes said first locking means (8) to adopt the second non-locking position of the blade (4). For this purpose, said second locking means (10) are in the form of a first piece (10) pivotally mounted about an axis (10a) passing through both said first piece (10) and the part of end of the two plates (6) of the handle portion (3). Said first piece (10) comprises a hook portion (10b) made in particular by the provision of a notch (10c) in the material of said first piece (10). This notch (10c) is adapted to cooperate, after pivoting from said first piece (10) to a first locking position, with a lug (8b) present on the lateral part of the flexible blade (8) to lock it in the locking position of the blade (4) of the knife (2) in the unfolded position. This first piece (10) also comprises an eccentric portion (10d) and adapted, after pivoting of said first piece (10) in the opposite direction to a second non-locking position, to lift said flexible blade (8) and disengaging the finger (9) of the blade (4) of the knife (2) from the recess (8a) of the flexible blade (8), in order to force said flexible blade (8) to adopt a second non-locking position of the blade (4) of the knife (2). Finally, said first piece (10) comprises a portion, opposite the notch, forming a lever (10e) and intended to allow the user to manipulate said first piece (10) and to move it from the first to the first second position.

La partie formant bras de levier (10e) se prolonge d'une longueur déterminée pour permettre, lorsque ladite première pièce (10) est dans la première position de verrouillage, de réaliser une garde pour protéger la main de l'utilisateur. Plus précisément, ladite partie formant levier (10e) se prolonge dans une direction sensiblement perpendiculaire à la direction de l'axe général de la lame (4) du couteau (2).The lever arm portion (10e) is extended by a predetermined length to allow, when said first piece (10) is in the first lock position, to provide a guard to protect the user's hand. More specifically, said lever portion (10e) extends in a direction substantially perpendicular to the direction of the general axis of the blade (4) of the knife (2).

Le système de verrouillage (1) de lame (4) selon l'invention comprend avantageusement des troisièmes moyens de verrouillage (11) aptes à adopter deux positions, une première position de verrouillage desdits deuxièmes moyens de verrouillage (10) dans la première position de verrouillage, et une deuxième position de non verrouillage. A cet effet, lesdits troisièmes moyens de verrouillage (11) se présentent sous la forme d'une deuxième pièce (11) montée pivotante autour d'un axe (11a) traversant à la fois ladite deuxième pièce (11) et la partie d'extrémité d'au moins une des deux platines (6) de la partie formant manche (3). Ladite deuxième pièce (11) comprend une partie formant butée (11b) apte à coopérer, après le pivotement de ladite deuxième pièce (11) jusqu'à la première position de verrouillage, avec ladite première pièce (10) pour empêcher son pivotement et verrouiller ladite première pièce (10) dans la première position de verrouillage. Ladite deuxième pièce (11) comprend, une partie, opposée à la partie formant butée (11b), formant levier (11c) et destinée à permettre à l'utilisateur de manipuler ladite deuxième pièce (11) et de la faire passer de la première à la deuxième position.The locking system (1) blade (4) according to the invention advantageously comprises third locking means (11) adapted to adopt two positions, a first locking position of said second locking means (10) in the first position of locking, and a second non-locking position. For this purpose, said third locking means (11) are in the form of a second piece (11) pivotally mounted about an axis (11a) passing through both said second piece (11) and the part of end of at least one of the two plates (6) of the handle portion (3). Said second piece (11) comprises an abutment portion (11b) adapted to cooperate, after the pivoting of said second piece (11) to the first locking position, with said first piece (10) to prevent its pivoting and locking said first piece (10) in the first locking position. Said second piece (11) comprises a portion, opposite to the abutment portion (11b) forming a lever (11c) and intended to allow the user to manipulate said second piece (11) and to move it from the first in the second position.

Ladite deuxième pièce (11) est plus précisément apte à pivoter jusqu'à faire butée contre la partie formant excentrique (10d) de la première pièce (10). Et, avantageusement, un bossage (10f) est formé sur ladite première pièce (10), entre la partie formant levier (10e) et l'excentrique (10d), de manière à encliqueter la partie formant butée (11b) de la deuxième pièce (11) entre ledit bossage (10f) et ladite partie formant levier (10e) de manière à maintenir ladite deuxième pièce (11) en position de verrouillage et éviter tout risque de déverrouillage accidentel.Said second piece (11) is more specifically adapted to pivot until abutting against the eccentric portion (10d) of the first piece (10). And, advantageously, a boss (10f) is formed on said first piece (10), between the lever portion (10e) and the eccentric (10d), so as to engage the abutment portion (11b) of the second piece (11) between said boss (10f) and said lever portion (10e) to maintain said second piece (11). in the locked position and avoid any risk of accidental unlocking.

Ladite deuxième pièce (11) permet également de verrouiller ladite première pièce (10) dans la première position de verrouillage qui est également une position dans laquelle la partie formant levier (10e) de ladite première pièce (10) forme une garde (12) pour la main de l'utilisateur. En d'autres termes, ladite deuxième pièce (11) permet de verrouiller ladite première pièce (10) en position de garde (12). Cela permet alors de sécuriser la garde (12) contre tout déverrouillage accidentel causé par exemple par un choc sur ladite garde (12) lorsque le couteau (2) est utilisé pour des opérations de frappes par exemple. Le positionnement de la main de l'utilisateur derrière ladite garde (12) réduit également les risques de déverrouillages accidentels car ladite main permet de garder la garde (12) en position et donc de garder la première pièce (10) dans la première position de verrouillage.Said second piece (11) also locks said first piece (10) in the first locking position which is also a position in which the lever portion (10e) of said first piece (10) forms a guard (12) for the user's hand. In other words, said second piece (11) makes it possible to lock said first piece (10) in the guard position (12). This then makes it possible to secure the guard (12) against any accidental unlocking caused for example by a shock on said guard (12) when the knife (2) is used for striking operations for example. The positioning of the user's hand behind said guard (12) also reduces the risk of accidental unlocking because said hand makes it possible to keep the guard (12) in position and thus to keep the first piece (10) in the first position of locking.

Pour permettre également un maintien de la lame (4) dans la deuxième position repliée de rangement, ladite lame (4) comprend dans la partie inférieure de son talon, destinée à être cachée entre les deux platines (6), une partie formant crochet (13). Cette partie formant crochet (13) est apte à coopérer avec un élément faisant saillie (non représenté) agencé sur une des deux platines (6) et en débordement intérieur. En d'autres termes, l'élément faisant saillie est agencé sur la paroi d'une des deux platines (6), entres lesdites deux platines (6). Ainsi, lorsque la lame (4) est repliée, la partie formant crochet (13) coopère avec l'élément faisant saillie pour s'encliqueter. De cette manière, la lame (4) est maintenue en position repliée et les risques de dépliage accidentel de la lame (4) du couteau (2) sont évités.To also allow a maintenance of the blade (4) in the second folded storage position, said blade (4) comprises in the lower part of its heel, intended to be hidden between the two plates (6), a hook portion ( 13). This hook portion (13) is adapted to cooperate with a projecting element (not shown) arranged on one of the two plates (6) and internal overflow. In other words, the projecting element is arranged on the wall of one of the two plates (6), between said two plates (6). Thus, when the blade (4) is folded, the hook portion (13) cooperates with the projecting member to snap. In this way, the blade (4) is held in the folded position and the risk of accidental unfolding of the blade (4) of the knife (2) are avoided.

D'une manière déjà connue de l'Homme du Métier, l'élément faisant saillie agencé entre les deux platines (6) peut être réalisé par un ressort fixé à une extrémité à une des parois interne de l'une des platines (6) et muni à l'autre extrémité d'une bille apte à coopérer avec la partie formant crochet (13) de la lame (4) du couteau (2).In a manner already known to those skilled in the art, the projecting element arranged between the two plates (6) can be made by a spring attached at one end to one of the internal walls of one of the plates (6). and provided at the other end with a ball adapted to cooperate with the hook portion (13) of the blade (4) of the knife (2).

Ainsi, lors de l'utilisation, la lame (4) du couteau (2) est par exemple initialement repliée et encliquetée entre les deux platines (6) de la partie formant manche (3). L'utilisateur doit donc exercer une force suffisante sur la lame (4) en tirant dessus pour la décliqueter et la faire passer dans la position dépliée d'utilisation. Lorsque la lame (4) arrive en butée sur la partie formant âme centrale (5), et que le doigt (9) de ladite lame (4) pénètre dans l'évidement (8a) présent dans la lame souple (8), l'utilisateur fait pivoter la première pièce (10) par l'intermédiaire de la partie formant levier (10e) de ladite première pièce (10) afin de la faire passer dans la première position de verrouillage de la lame souple (8).Thus, in use, the blade (4) of the knife (2) is for example initially folded and snapped between the two plates (6) of the handle portion (3). The user must therefore exert sufficient force on the blade (4) by pulling it to unclip it and move it into the unfolded position of use. When the blade (4) comes to a stop on the central core portion (5), and that the finger (9) of said blade (4) penetrates the recess (8a) present in the flexible blade (8), the user rotates the first piece (10) by via the lever portion (10e) of said first member (10) to pass into the first locking position of the flexible blade (8).

L'utilisateur fait ensuite pivoter la deuxième pièce (11) par l'intermédiaire de la partie formant levier (11c) de ladite deuxième pièce (11) pour la faire passer dans la première position de verrouillage de la première pièce (10).The user then rotates the second piece (11) through the lever portion (11c) of said second piece (11) to pass into the first locking position of the first piece (10).

La lame (4) du couteau (2) est ainsi verrouillée en position d'une manière optimale et tout déverrouillage accidentel est supprimé.The blade (4) of the knife (2) is thus locked in position optimally and any accidental unlocking is removed.

La configuration des deux pièces pivotantes (10, 11) jouant les rôles des deuxièmes (10) et troisièmes (11) moyens de verrouillage donne la possibilité à l'utilisateur d'effectuer l'opération de verrouillage et déverrouillage de la lame (4) du couteau (2) en une seule action. En effet, en agissant uniquement sur la deuxième pièce (11) et en la faisant pivoter pour la faire passer dans la première position de verrouillage, celle-ci fait automatiquement passer la première pièce pivotante (10) dans la première position de verrouillage. Les opérations de verrouillage et déverrouillage des deuxièmes (10) et troisièmes (11) moyens de verrouillage peuvent être effectuée d'une seule main.The configuration of the two pivoting parts (10, 11) playing the roles of the second (10) and third (11) locking means gives the user the possibility of performing the locking and unlocking operation of the blade (4) of the knife (2) in one action. Indeed, by acting only on the second part (11) and by rotating it to pass in the first locking position, it automatically passes the first pivoting part (10) in the first locking position. The locking and unlocking operations of the second (10) and third (11) locking means can be performed with one hand.

En référence aux figures 12 et 13, les premiers moyens de verrouillage (8) sont réversibles en position et les deuxièmes (10) et troisièmes (11) moyens de verrouillage sont aptes à être montés d'un côté ou de l'autre de la partie formant manche (3). De cette manière le système de verrouillage (1) de lame (4) en position dépliée est réversible et peut se monter autant sur un couteau (2) pour gaucher que sur un couteau (2) pour droitier.With reference to Figures 12 and 13 , the first locking means (8) are reversible in position and the second (10) and third (11) locking means are adapted to be mounted on one side or the other of the handle portion (3). In this way the locking system (1) blade (4) in the unfolded position is reversible and can be mounted as much on a knife (2) left-handed than on a knife (2) for right-handed.

Comme il ressort de ce qui précède, l'invention fournit ainsi un système de verrouillage de lame en position dépliée pour couteau (2) à lame (4) repliable dont le verrouillage de ladite lame (4) en position dépliée est optimal. Le système de verrouillage (1) selon l'invention a l'avantage d'être réversible pour se monter autant sur un couteau (2) pour gaucher que sur un couteau (2) pour droitier. Le système de verrouillage selon l'invention fourni également une garde (12) pour protéger la main de l'utilisateur et est de conception simple, sure et rationnelle.As is apparent from the foregoing, the invention thus provides a blade locking system in the unfolded position for knife (2) blade (4) foldable whose locking of said blade (4) in the unfolded position is optimal. The locking system (1) according to the invention has the advantage of being reversible to mount as much on a knife (2) left-handed than on a knife (2) for right-handed. The locking system according to the invention also provides a guard (12) to protect the hand of the user and is simple, safe and rational design.

Il va de soi que l'invention n'est pas limitée à la forme de réalisation décrite ci-dessus à titre d'exemple mais qu'elle s'étend à toutes les formes de réalisations couvertes par les revendications ci-annexées.It goes without saying that the invention is not limited to the embodiment described above by way of example but that it extends to all embodiments covered by the appended claims.
