Abstract

The device has a wedge part (1) with a guiding shank (3) sliding between a back (10) of a handle and a spacer (7) pushed by a spring. A front shape (4) of the part is locked on a blade heel and the back. A projection extends from a cavity (11) to enable its handling. An extension (2) supported on an axis (14) obstructs an opening (8). The shape positioned inside the heel abuts on a surface of the device in a closed position.

Description

La présente invention concerne un dispositif pour bloquer la lameThe present invention relates to a device for locking the blade

d'un couteau pliant en position ouverte par coincement de grande sécurité ou la maintenir fermée dans son manche. Le dispositif peut-être actionné par un droitier ou un gaucher, de plus il permet un rattrapage de jeu automatique du dispositif.  of a folding knife in the open position by wedging very securely or keep it closed in its handle. The device can be actuated by a right-handed or a left-handed person, moreover it allows an automatic backlash adjustment of the device.

Les dispositifs de blocage de lame sur les couteaux pliants ne sont pas assez sécurisants, ce qui occasionne des blessures par la lame en utilisant le couteau.  The blade locking devices on the folding knives are not sufficiently secure, which causes injuries by the blade when using the knife.

Les dispositifs de blocage sont tout particulièrement adaptés pour 10 les droitiers et non pour les gauchers, enfin, les mécanismes dont ils sont pourvus prennent souvent du jeu dans le temps.  The locking devices are particularly suitable for right-handers and not for left-handers, finally, the mechanisms with which they are provided often take play over time.

Le dispositif selon l'invention permet de remédier à cet inconvénient, il comporte en effet une première caractéristique qui est une pièce coin mobile positionnée dans le dos d'un couteau en tôle pliée, 15 et permet d'être manipulée grâce à un logement effectué sur le dessus qui laisse apparaître une saillie située sur la pièce coin qui dépasse, faisant office de bouton poussoir.  The device according to the invention makes it possible to remedy this drawback, it in fact comprises a first characteristic which is a movable corner piece positioned in the back of a knife made of folded sheet metal, and makes it possible to be handled thanks to a housing made on the top which reveals a projection located on the corner piece which protrudes, acting as a push button.

La pièce coin étant mobile et poussée par un ressort en spiral permet à celle-ci de venir se positionner sur l'avant entre le dos du 20 manche et le dessus incliné du talon de la lame en position ouverte qui ainsi forme un espace conique, offrant un blocage par coincement de celle-ci, ce qui évite tout jeu, et transmet ainsi l'effort du talon de la lame sur le dos du manche du couteau.  The corner piece being mobile and pushed by a spiral spring allows it to come to position on the front between the back of the handle and the inclined top of the heel of the blade in the open position which thus forms a conical space, offering a blockage by wedging it, which avoids any play, and thus transmits the force of the heel of the blade on the back of the knife handle.

Le dispositif placé au centre sur le dessus du couteau permet d'être 25 manipulé par un gaucher ou un droitier.  The device placed in the center on top of the knife allows it to be handled by a left-handed or right-handed person.

Les dessins annexés illustrent l'invention La figure 1 représente en coupe, le dispositif de l'invention.  The accompanying drawings illustrate the invention. FIG. 1 represents in section, the device of the invention.

La figure 2 représente en coupe la pièce principale du dispositif.  Figure 2 shows in section the main part of the device.

En référence à ses dessins, le dispositif comporte une pièce coin 30 (1) mobile monobloc en acier pourvue d'une queue de guidage coulissant dans le dos (10) plié du couteau, et prenant appui sur l'intercalaire (7) qui est aménagé pour loger le ressort (6) placé derrière la queue (3) de la pièce coin. 2.  With reference to its drawings, the device comprises a corner piece 30 (1) movable one-piece steel provided with a guide tail sliding in the back (10) folded of the knife, and bearing on the interlayer (7) which is fitted to accommodate the spring (6) placed behind the tail (3) of the corner piece. 2.

"1Sur l'avant la pièce coin (1) monobloc dans sa partie inférieurei comprend une forme (4) complémentaire de celle du dessous du talon (13) de la lame, mais aussi une surface (5) permettant à celle-ci de recevoir en buté la surface plate du talon (9) en position fermée.  "1On the front, the one-piece corner piece (1) in its lower parti comprises a shape (4) complementary to that of the underside of the heel (13) of the blade, but also a surface (5) allowing it to receive in abutment the flat surface of the heel (9) in the closed position.

En position ouverte, le talon (15) de la lame offre par son angle un espace conique entre celui-ci et le dessus du dos plié (10) du manche, la pièce coin (1) poussée par le ressort (6) vient se positionner dans cet espace permettant le blocage par coincement du talon (15) de la lame.  In the open position, the heel (15) of the blade offers, by its angle, a conical space between it and the top of the folded back (10) of the handle, the corner piece (1) pushed by the spring (6) comes position in this space allowing blocking by wedging the heel (15) of the blade.

Selon une variante illustrée, la partie avant supérieure de la pièce 10 coin (1) monobloc comporte un prolongement (2) permettant le guidage de celle-ci, mais aussi coulissant en avant d'obturé une fenêtre (8) ménagée à l' avant sur le dos (10) plié du manche.  According to an illustrated variant, the upper front part of the piece 10 corner (1) in one piece has an extension (2) allowing the guide thereof, but also sliding in front of closed a window (8) formed at the front on the folded back (10) of the handle.

Un axe (14) transversal permet au prolongement (2) d'avoir un appui.  A transverse axis (14) allows the extension (2) to have a support.

La pièce coin (1) monobloc possède sur le dessus un saillie (12) venant se positionner dans le logement (11) prévu sur le dos du couteau qui permet son maniement.  The one-piece corner piece (1) has a projection (12) on top positioned in the housing (11) provided on the back of the knife which allows its handling.

Le dispositif selon l'invention est particulièrement destiné pour bloquer en position ouverte la lame d'un couteau pliant mais aussi la 20 maintenir fermée dans son manche par pression.  The device according to the invention is particularly intended for blocking in the open position the blade of a folding knife but also for keeping it closed in its handle by pressure.
