Abstract

The device comprises a knife provided with a stop (4) which prevents the cutting edge of a blade (1) coming in contact with the spring (2) in its course of closure. The stop is formed by a hardened metal rod traversing two lockplates (7), and perpendicularly mounted with respect to the blade pivoting plane. A handle divided in two parts holds the stop preventing its translation movement. The stop traverses the two lockplates and the two parts in which the handle is divided, at the same time. When closure of the knife, a catch pin (6) hits the stop preventing the blade coming in contact with the spring.

Description

"Dispositif évitant au fil de la lame de tous couteaux fermants de
venir en contact avec le ressort, lors de la fermeture de celleci ". "Device avoiding over the blade all closing knives
come into contact with the spring when closing it ".

L'invention concerne le domaine des couteaux. The invention relates to the field of knives.

Elle vise plus particulièrement les couteaux fermants dont le montage permet
cette adaptation.It is more particularly aimed at closing knives, the mounting of which allows
this adaptation.

Pour l'instant il n'est pas connu d'antériorité, les lames de couteaux fermants frappant toutes le ressort lors de leur fermeture. For the time being, no prior art is known, the blades of closing knives all striking the spring when they are closed.

La présente invention a pour but de doter le couteau d'une butée arrentant la lame dans sa fin de course, avant de venir en contact avec le ressort
Cette butée est constituée d'une tige cylindrique en métal trempé, traversant les deux platines et montée perpendiculairement au plan de rotation de la lame.The object of the present invention is to provide the knife with a stop which arrives the blade at its end of travel, before coming into contact with the spring.
This stop consists of a cylindrical rod of hardened metal, crossing the two plates and mounted perpendicular to the plane of rotation of the blade.

Le point de contact "butée-lame" sera ajusté, pour une fermeture prédise, par un meulage minutieux du "mentonnet" de la lame. The point of contact "stop-blade" will be adjusted, for a predicted closure, by careful grinding of the "flange" of the blade.

De toute façon, l'invention sera mieux comprise à l'aide de la description qui
suit, en référence au dessin schématique annexé représentant,à titre d'exemple, un type de couteau fermant sur lequel est implanté le dispositif.In any case, the invention will be better understood using the description which
follows, with reference to the appended schematic drawing representing, by way of example, a type of closing knife on which the device is installed.

Figure 1 est une vue en coupe du couteau ouvert. Figure 1 is a sectional view of the open knife.

Figure 2 est une vue en coupe du couteau fermé
Figure 3 est une vue de dessus du couteau fermé version butée courte
Figure 4 est une vue de dessus du couteau fermé version butée longue
La butée (4), composée d'une tige cylindrique est intégrée en cours de montage des platines (7) et tenue en traration par les cEs(9). Figure 2 is a sectional view of the closed knife
Figure 3 is a top view of the closed knife short stop version
Figure 4 is a top view of the closed knife long stop version
The stop (4), composed of a cylindrical rod is integrated during assembly of the plates (7) and held in traration by the cEs (9).

Sa position est déterminée en fonction du type de couteau et de lame. Its position is determined according to the type of knife and blade.

A la fermeture de la lame (1), le mentonnet (6) vient frapper 'a butée (4) et évite à la lame (1) de venir en contact avec le ressort (2). When the blade (1) closes, the chin (6) strikes the stop (4) and prevents the blade (1) from coming into contact with the spring (2).

Pour permettre d'ajuster le jeu (8), un meulage minutieux du mentonnet (6) peut être réalisé. To allow the clearance (8) to be adjusted, meticulous grinding of the flange (6) can be carried out.

Selon une variante illustrée figure 4, la butée (4) peut traverser à la fois les
platines (7) et les côtes (9).According to a variant illustrated in FIG. 4, the stop (4) can pass through both the
plates (7) and ribs (9).

L'arrêt en translation de la butée (4) se ferait alors par rivetage de ses
extrémités (10) . The stop in translation of the stop (4) would then be by riveting its
ends (10).
