Description
//- 2809654// - 2809654
La présente invention concerne un dispositif de blocage et déblocage de lame sur couteau pliant à pompe. The present invention relates to a blade locking and unlocking device on a folding pump knife.
Traditionnellement, la lame présente une encoche supérieure qui reçoit la pompe située dans le dos du couteau. Le blocage est réalisé quand la tête de la pompe est engagée dans l'encoche de la lame, le soulèvement de la pompe débloque la lame. En général, la pompe est articulée en son milieu, et l'appui sur la partie opposée soulève la tête et débloque la lame. Ce principe est très efficace mais, I'ouverture du couteau nécessite l'utilisation des deux mains. Le dispositif, selon l'invention, permet de remédier à cet inconvénient, tout en gardant le principe de fonctionnement et son efficacité. Ce dispositif permet de verrouiller et déverrouiller la lame en position ouverte et de plus, permet aussi, le verrouillage et le déverrouillage de la position fermée. C'est un atout de sécurité d'utilisation et dans le port du couteau. L'invention consiste à rajouter une came, articulée autour du pivot, qui dans sa15 rotation, soulève la pompe et ensuite entraîne la lame dans sa rotation. Cette came Traditionally, the blade has an upper notch which receives the pump located in the back of the knife. Blocking is achieved when the pump head is engaged in the notch of the blade, lifting the pump unlocks the blade. In general, the pump is articulated in the middle, and pressing on the opposite part lifts the head and unlocks the blade. This principle is very effective, but opening the knife requires the use of two hands. The device according to the invention overcomes this drawback, while keeping the operating principle and its efficiency. This device makes it possible to lock and unlock the blade in the open position and, moreover, also allows the locking and unlocking of the closed position. It is an asset of safety in use and in the carrying of the knife. The invention consists in adding a cam, articulated around the pivot, which in its rotation, lifts the pump and then drives the blade in its rotation. This cam
étant active dans les deux sens, la manoeuvre du couteau se fait d'un seul doigt. being active in both directions, the operation of the knife is done with one finger.
Les dessins annexés illustrent l'invention: La figure 1 représente le couteau ouvert et verrouillé, selon une coupe passant par la face latérale externe de la came.20 La figure 2 représente, le couteau ouvert en vue de dessus. La figure 3 représente le couteau fermé et verrouillé selon une coupe passant par la face latérale externe de la came. En référence à ces dessins, le dispositif comprend une lame (4) guidée entre les deux platines (1),(2) et articulée autour du pivot (8) solidaire des deux platines (1),(2). La tête de la pompe (3) vient se clamper, sous un l'effet d'un ressort non représenté, dans les encoches de la lame (4). La platine (2) présente un dégagement permettant le logement de la came (5). Le guidage en rotation de la came (5) est assuré par le diamètre extérieur de la rondelle (9) positionnée par son alésage sur le pivot (8). Cette rondelle (9) assure aussi le guidage latéral de la lame (4) entre les30 deux platines (1),(2). La came (5) présent une lumière qui autorise un mouvement relatif de rotation de la lame (4) limité par la goupille (7) . Cette came (5) présente aussi deux encoche extérieures dans lesquelles la butée (6) vient se loger pour autoriser le verrouillage de la pompe (3) . Pour fermer le couteau, le pouce se positionne sur le bossage de la came (5) The accompanying drawings illustrate the invention: FIG. 1 represents the knife open and locked, in a section passing through the external lateral face of the cam. FIG. 2 represents, the knife open in top view. FIG. 3 represents the knife closed and locked in a section passing through the external lateral face of the cam. With reference to these drawings, the device comprises a blade (4) guided between the two plates (1), (2) and articulated around the pivot (8) integral with the two plates (1), (2). The pump head (3) is clamped, under the effect of a spring, not shown, in the notches of the blade (4). The plate (2) has a clearance allowing the housing of the cam (5). The cam (5) is guided in rotation by the outside diameter of the washer (9) positioned by its bore on the pivot (8). This washer (9) also provides lateral guiding of the blade (4) between the two plates (1), (2). The cam (5) has a light which allows a relative movement of rotation of the blade (4) limited by the pin (7). This cam (5) also has two external notches in which the stop (6) is housed to authorize the locking of the pump (3). To close the knife, the thumb is positioned on the cam boss (5)
et commence le rotation dans le sens de la fermeture, dès le début, la came (5) soulève la pompe (3) grâce à la butée (6) et de ce fait déverrouille la lame (4). and starts the rotation in the closing direction, from the start, the cam (5) lifts the pump (3) thanks to the stop (6) and thereby unlocks the blade (4).
Ensuite, en continuant la rotation la came (5) entraîne la lame (4) par l'intermédiaire de la goupille (7) jusqu'à la position fermée. La position relative de la came (5) par rapport à la lame (4) autorise le verrouillage de la pompe (3).40 Pour ouvrir le couteau, le pouce se positionne sur le bossage de la came (5) et commence la rotation dans le sens de l'ouverture. Et comme à la fermeture, pendant les premiers trente degrés, la came (5) soulève la pompe (3) et ensuite entraîne la lame (4). Selon une variante non illustrée, la came peut se manoeuvrer au travers de la Then, by continuing the rotation the cam (5) drives the blade (4) via the pin (7) to the closed position. The relative position of the cam (5) relative to the blade (4) allows the pump (3) to be locked. 40 To open the knife, the thumb is positioned on the cam boss (5) and begins rotation in the direction of opening. And as when closing, during the first thirty degrees, the cam (5) lifts the pump (3) and then drives the blade (4). According to a variant not illustrated, the cam can be maneuvered through the
platine si celle-ci présente une lumière semi-circulaire permettant le passage d'un entraîneur. platinum if it has a semi-circular light allowing the passage of a coach.
A titre d'exemple, non limitatif, le bossage de la came (5) peut être proéminent pour faciliter la manoeuvre avec des mains mouillées ou avec des gants. Le dispositif selon l'invention est particulièrement destiné à la manoeuvre des50 couteaux à pompe pour les rendre manoeuvrable avec un seul doigt. By way of example, without limitation, the boss of the cam (5) can be prominent to facilitate maneuvering with wet hands or with gloves. The device according to the invention is particularly intended for the operation of the pump knives to make them maneuverable with a single finger.
