Description

La présente invention a essentiellement pour objet un couteau fermant perfectionné.The present invention essentially relates to an improved closing knife.

On connait depuis fort longtemps des couteaux fermants comprenant un manche en bois sur lequel est montée pivotante une lame.Closing knives have been known for a very long time including a wooden handle on which a blade is pivotally mounted.

Toutefois, le bois du manche peut se gonfler sous l'effet de l'humidité, de sorte que le frottement du talon de la lame lors de son pivotement par rapport au manche rend bien souvent difficile l'ouverture ou la fermeture de ladite lame.However, the wood of the handle can swell under the effect of humidity, so that the friction of the heel of the blade when it is pivoted relative to the handle very often makes it difficult to open or close said blade.

En outre, le montage de la lame sur le manche exige un certain nombre d'opérations qui, dans le cadre d'une fabrication en grande série, peuvent grever le prix des couteaux.In addition, mounting the blade on the handle requires a certain number of operations which, in the context of mass production, can increase the price of knives.

Aussi, la présente invention a pour but de remédier notamment aux inconvénients ci-dessus en proposant un couteau fermant essentiellement caractérisé en ce que le talon de la lame est monté pivotant sur une pièce intermédiaire en matériau plastique, composite ou analogue, insérée et fixée de préférence par collage dans un logement prévu à l'une des extrémités du manche.Also, the present invention aims to remedy in particular the above drawbacks by proposing a closing knife essentially characterized in that the heel of the blade is pivotally mounted on an intermediate piece of plastic, composite or similar material, inserted and fixed from preferably by gluing in a housing provided at one end of the handle.

Suivant une autre caractéristique de ce couteau, une lame-ressort est fixée par tout moyen approprié tel que clippage, emmanchement, surmoulage ou analogue, dans la pièce intermédiaire faisant saillie du manche après montage, ladite lame-ressort coopérant avec le talon de la lame pour la maintenir de façon élastique en position ouverte ou fermée.According to another characteristic of this knife, a leaf spring is fixed by any suitable means such as clipping, fitting, overmolding or the like, in the intermediate part projecting from the handle after assembly, said leaf spring cooperating with the heel of the blade to keep it resiliently in the open or closed position.

On comprend donc qu'il n'y a plus de problème de positionnement de la lame-ressort sur le manche, puisque celle-ci est initialement solidaire de la pièce intermédiaire qui forme en quelque sorte un bloc qu'il est facile d'enficher et de coller au bout du manche, d'où une simplification importante de la fabrication du couteau.It is therefore understood that there is no longer any problem of positioning the leaf spring on the handle, since the latter is initially secured to the intermediate piece which in a way forms a block which is easy to insert and to stick to the end of the handle, hence a significant simplification of the manufacture of the knife.

Selon encore une autre caractéristique du couteau selon cette invention, la forme de la pièce intermédiaire est telle qu'elle peut constituer un moyen détrompeur à l'insertion de ladite pièce dans le logement du manche pour que la fente prévue dans cette pièce pour recevoir de façon pivotante le talon de la lame soit en coïncidence avec la fente sur le manche devant recevoir la lame en position repliée.According to yet another characteristic of the knife according to this invention, the shape of the intermediate piece is such that it can constitute a polarizing means at the insertion of said piece into the housing of the handle so that the slot provided in this piece for receiving pivoting the heel of the blade is in coincidence with the slot on the handle to receive the blade in the folded position.

On précisera encore ici que l'extrémité de la pièce intermédiaire faisant saillie du manche peut comporter un tampon ou analogue protégeant ladite extrémité contre les chocs du talon de la lame lors de son ouverture.It will also be specified here that the end of the intermediate piece projecting from the handle may include a buffer or the like protecting said end against the impact of the heel of the blade when it is opened.

Le couteau fermant selon cette invention peut encore comporter une virole métallique montée sur l'extrémité de la pièce intermédiaire faisant saillie du manche après montage par collage dans ce manche.The closing knife according to this invention may also include a metal ferrule mounted on the end of the intermediate piece projecting from the handle after mounting by gluing in this handle.

Mais d'autres caractéristiques et avantages de l'invention apparaîtront mieux dans la description détaillée qui suit et se réfère aux dessins annexés, donnés uniquement à titre d'exemple, et dans lesquels.However, other characteristics and advantages of the invention will appear better in the detailed description which follows and refers to the appended drawings, given solely by way of example, and in which.

La figure 1 est une vue de côté et en coupe verticale d'un couteau fermant conforme à cette invention.Figure 1 is a side view in vertical section of a closing knife according to this invention.

La figure 2 est une vue en coupe suivant la ligne II-II de la figure 1.Figure 2 is a sectional view along line II-II of Figure 1.

On voit sur ces figures un couteau fermant comprenant un manche 1 de préférence en bois sur lequel est montée une lame pivotante 2 comportant un talon 3.These figures show a closing knife comprising a handle 1, preferably of wood, on which is mounted a pivoting blade 2 comprising a heel 3.

Conformément à l'invention, le talon 3 de la lame 2 est monté pivotant grâce à un axe ou analogue 4 sur une pièce intermédiaire 5 en un matériau plastique, composite ou autre, cette pièce intermédiaire étant insérée et fixée par collage dans un logement 6 formé par un perçage à l'une des extrémités du manche 1.According to the invention, the heel 3 of the blade 2 is pivotally mounted by means of an axis or the like 4 on an intermediate piece 5 of a plastic, composite or other material, this intermediate piece being inserted and fixed by gluing in a housing 6 formed by a hole in one end of the handle 1.

On a montré en 7 sur les figures une lame-ressort susceptible de coopérer avec le talon 3 de la lame 2 et qui est fixée par clippage, emmanchement ou analogue, et de préférence par surmoulage, dans la pièce intermédiaire 5, cette dernière comportant une partie 5a qui fait saillie du manche 1, comme cela apparaît clairement sur la figure 1.7 has been shown in the figures a leaf spring capable of cooperating with the heel 3 of the blade 2 and which is fixed by clipping, fitting or the like, and preferably by overmolding, in the intermediate part 5, the latter comprising a part 5a which projects from the handle 1, as is clearly shown in FIG. 1.

Ainsi, la pièce intermédiaire 5 et la lame-ressort 7 constituent une pièce monobloc qui, d'une part, comporte une fente 8 dans laquelle peut être facilement monté le talon 3 de la lame 2 au moyen de l'axe 4, et qui, d'autre part peut être immédiatement fixée par collage dans le logement 6 du manche 1, ce qui, comme on le comprend, facilite considérablement la fabrication du couteau par rapport à un couteau classique devant comporter une lame-ressort telle que 7.Thus, the intermediate piece 5 and the leaf spring 7 constitute a single piece which, on the one hand, has a slot 8 in which can be easily mounted the heel 3 of the blade 2 by means of the axis 4, and which , on the other hand can be immediately fixed by gluing in the housing 6 of the handle 1, which, as it is understood, considerably facilitates the manufacture of the knife compared to a conventional knife having to include a leaf spring such as 7.

La pièce intermédiaire 5 peut tout simplement présenter une forme cylindrique susceptible de s'engager, par son extrémité 5b dans un perçage correspondant et lui aussi cylindrique formant le logement 6, dans le manche 1.The intermediate piece 5 can simply have a cylindrical shape capable of engaging, by its end 5b in a corresponding bore and also cylindrical forming the housing 6, in the handle 1.

Suivant la réalisation particulière visible sur les figures, la pièce intermédiaire 5 est formée de deux parties cylindriques désaxées constituant respectivement les parties 5a et 5b et assurant le centrage de la pièce 5 dans le logement 6 possédant une forme correspondante. On observera qu'avec une telle configuration, on réalise un dé- trompage à l'insertion de la pièce 5 dans le logement 6 pour que la fente 8 prévue dans la pièce 5 pour recevoir le talon 3 de la lame 2 soit en coïncidence avec la fente 9 prévue sur le manche 1 et pouvant recevoir, comme cela est connu en soi, la lame 2 en position repliée.According to the particular embodiment visible in the figures, the intermediate part 5 is formed of two offset axial parts respectively constituting the parts 5a and 5b and ensuring the centering of the part 5 in the housing 6 having a corresponding shape. It will be observed that with such a configuration, a reduction is made when inserting the part 5 into the housing 6 so that the slot 8 provided in the part 5 for receiving the heel 3 of the blade 2 is in coincidence with the slot 9 provided on the handle 1 and which can receive, as is known per se, the blade 2 in the folded position.

Il est important de remarquer ici que la pièce intermédiaire 5 étant en matériau composite ou plastique demeurera insensible à l'humidité, de sorte que le frottement, au pivotement, du talon 3 de la lame 2 sera, même à la longue, toujours le même, ce qui n'était pas le cas avec une lame montée pivotante directement sur le manche en bois du couteau. Au surplus, la fixation de la lame 2 par l'axe 4 sur la pièce intermédiaire 5 ne posera aucun problème spécial et n'exigera aucune précaution particulière, eu égard au frottement entre lame 2 et pièce 5.It is important to note here that the intermediate piece 5 being made of composite or plastic material will remain insensitive to moisture, so that the friction, when pivoting, of the heel 3 blade 2 will, even in the long run, always be the same, which was not the case with a blade pivotally mounted directly on the wooden handle of the knife. Furthermore, the fixing of the blade 2 by the axis 4 on the intermediate part 5 will not pose any special problem and will not require any particular precaution, having regard to the friction between blade 2 and part 5.

On a montré en 10 sur la figure 1 un tampon ou analogue protégeant l'extrémité 5a de la pièce intermédiaire 5 faisant saillie du manche 1, contre les chocs éventuels du talon 3 de la lame 2 lors de son ouverture qui est la position illustrée sur la figure 1.There has been shown at 10 in FIG. 1 a pad or the like protecting the end 5a of the intermediate piece 5 projecting from the handle 1, against possible impacts from the heel 3 of the blade 2 when it is opened, which is the position illustrated on Figure 1.

Egalement, l'extrémité 5a de la pièce intermédiaire 5 fixée de préférence par collage sur le manche 1, peut être entourée, bien que cela ne soit nullement obligatoire, par une virole métallique repérée en 11.Also, the end 5a of the intermediate piece 5 preferably fixed by gluing to the handle 1, can be surrounded, although this is in no way obligatory, by a metallic ferrule marked at 11.

Ainsi, la périphérie de l'extrémité saillante Sa de la pièce 5 sera totalement protégée par la virole 11 qui, en outre, pourra conférer au couteau un aspect esthétique d'ensemble particulier.Thus, the periphery of the projecting end Sa of the part 5 will be completely protected by the ferrule 11 which, in addition, may give the knife a particular overall aesthetic appearance.

On a donc réalisé suivant l'invention un couteau fermant qui peut être facile et peu coûteux à fabriquer alors même qu'il comporte une lame-ressort agissant sur le talon de la lame, et qui ne présentera aucune irrégularité ou défaut de frottement au pivotement de ladite lame, quelles que soient les conditions dans lesquelles on utilise le couteau.A closing knife has therefore been produced according to the invention which can be easy and inexpensive to manufacture even though it has a leaf spring acting on the heel of the blade, and which will have no irregularity or lack of friction in pivoting. of said blade, whatever the conditions under which the knife is used.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple.Of course, the invention is in no way limited to the embodiment described and illustrated, which has been given only by way of example.

C'est ainsi que, compte tenu de l'outillage de présentation et de fixation de la lame du couteau via la pièce intermédiaire dans le logement du manche, ladite pièce intermédiaire et ledit logement peuvent être tout simplement cylindriques. Egalement, le matériau plastique ou composite constituant la pièce intermédiaire peuvent être quelconques à condition toutefois de permettre une fixation solide par collage de la pièce intermédiaire dans le logement du manche. Enfin, la lame-ressort peut avoir une forme quelconque et être rendue solidaire de la pièce intermédiaire d'une manière également quelconque.Thus, given the tools for presenting and fixing the blade of the knife via the intermediate piece in the housing of the handle, said intermediate piece and said housing can be quite simply cylindrical. Also, the plastic or composite material constituting the intermediate piece may be any provided, however, of allowing a solid fixing by gluing of the intermediate piece in the housing of the handle. Finally, the leaf spring can have any shape and be made integral with the intermediate piece in any way.

C'est dire que l'invention comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci sont effectuées suivant son esprit.This means that the invention includes all the technical equivalents of the means described, as well as their combinations if these are carried out according to the spirit.
