Abstract

The pocket knife (1) comprises lateral sides (18) which serve as a handle and at least one utensil able to pivot or slide in a plane parallel to the internal faces of the sides. One of the utensils is a cigar cutter which comprises two rounded scissors arms (10,11) pivoting about a first axis (16). One end of the first arm (10) pivots about a second axis (14) enabling it to be extracted from the knife. The cigar cutter also includes a leaf spring (12) enabling the scissors arms to be held apart when they have been extracted from the knife. The leaf spring limits also the pivoting travel of the second arm about the first axis. A flexible dorsal strip (13) transmits through the leaf spring a constant force to the scissors second arm.

Description

La présente invention concerne un couteau de poche multifonctionnel comportant des côtes latérales servant de poignée pour le couteau, les faces internes desdites côtes latérales étant sensiblement parallèles, et au moins un ustensile pouvant pivoter ou coulisser dans un plan parallèle auxdites faces internes des côtes latérales, l'un desdits ustensiles consistant en un coupe-cigares.The present invention relates to a pocket knife multifunctional with side ribs serving as a handle for knife, the internal faces of said lateral ribs being substantially parallel, and at least one utensil that can pivot or slide in a plane parallel to said internal faces of the lateral ribs, one of said utensils consisting of a cigar cutter.

Les couteaux de poche multifonctionnels de type « couteau suisse » comportent de manière générale une ou plusieurs lames coupantes et/ou un ou plusieurs ustensiles pivotant entre les deux côtes du couteau. Le succès de ces couteaux provient notamment de la grande variété d'ustensiles disponibles, permettant une grande polyvalence et de nombreuses utilisations dans divers domaines d'applications.Multifunctional pocket knives of the “Swiss knife” type generally comprise one or more cutting blades and / or one or several utensils swiveling between the two sides of the knife. The success of these knives comes mainly from the wide variety of utensils available, allowing great versatility and many uses in various areas of application.

Un but de la présente invention est d'étendre encore la gamme d'ustensiles disponibles sur les couteaux polyvalents de type couteau suisse, et de proposer un nouveau type de couteau spécialisé.An object of the present invention is to further extend the range utensils available on multipurpose Swiss Army knife type knives, and to offer a new type of specialized knife.

Ce but est atteint selon la présente invention grâce à un couteau, de poche multifonctionnel comportant un coupe-cigares présentant les caractéristiques de la partie caractérisante de la revendication 1.This object is achieved according to the present invention by means of a knife, multifunctional pocket with a cigar cutter presenting the characteristics of the characterizing part of claim 1.

Des formes de réalisation préférentielles sont par ailleurs indiquées dans les revendications dépendantes.Preferred embodiments are further indicated in the dependent claims.

Les couteaux de poche équipés de coupe-cigares sont naturellement connus (par exemple US-A-1,717,925, US-A-1,454,994, FR-A-418.164, DE-A-25866, DE-A-22051). Ils sont le plus souvent de type « guillotine », c'est-à-dire qu'ils comportent généralement une seule lame mobile perpendiculairement à la ligne de coupe. On connaít aussi des coupe-cigares de type « ciseaux », c'est-à-dire comportant deux lames pivotant l'une par rapport à l'autre autour d'un axe liant les deux lames.Pocket knives fitted with cigar cutters are naturally known (for example US-A-1,717,925, US-A-1,454,994, FR-A-418.164, DE-A-25866, DE-A-22051). They are most often of the type "Guillotine", that is to say that they generally have a single blade movable perpendicular to the cutting line. We also know cigar cutters type "scissors", that is to say comprising two blades pivoting with respect to each other around an axis connecting the two blades.

On connaít également déjà des couteaux de poche polyvalents, notamment de couteaux suisses, munis de ciseaux, mais la robustesse requise et l'écartement nécessaire des branches les rendent cependant inadéquats pour couper l'extrémité de cigares, en particulier pour couper des cigares de fort diamètre. Les fumeurs de cigare désirant les couper au moyen d'un couteau suisse utilisent donc généralement la grande lame de couteau, ce qui est peu pratique et dangereux.We also already know versatile pocket knives, in particular Swiss knives, fitted with scissors, but the robustness required and the necessary spacing of the branches, however, make them unsuitable for cut the end of cigars, especially for cutting strong cigars diameter. Cigar smokers wishing to cut them with a knife Swiss therefore generally use the large knife blade, which is not very practical and dangerous.

Ces inconvénients sont supprimés par le couteau de l'invention, dont une forme de réalisation préférentielle sera mieux comprise à l'aide de la description donnée à titre d'exemple et illustrée par les figures annexées qui montrent :These drawbacks are eliminated by the knife of the invention, including a preferred embodiment will be better understood using the description given by way of example and illustrated by the appended figures which show:

La figure 1 une vue de côté de couteau selon l'invention avec un coupe-cigares illustré avec les deux branches de ciseau en position écartée.Figure 1 a side view of knife according to the invention with a cigar cutter illustrated with the two scissor arms in the separated position.

La figure 2 une vue de côté de couteau selon l'invention avec un coupe-cigares illustré avec les deux branches de ciseau en position resserrée.Figure 2 a side view of knife according to the invention with a cigar cutter shown with the two scissor arms in the closed position.

Le couteau 1 comporte de manière générale deux côtes latérales, le plus souvent recouvertes de plastique, avec des faces internes sensiblement planes et parallèles, entre lesquelles sont disposés divers ustensiles pouvant être extraits individuellement par pivotement ou coulissement dans un plan parallèle aux faces internes. Les côtes latérales servent de poignée pour le couteau. Pour la simplicité du dessin, le couteau a été représenté ici comme si une des côtes latérales 18 avait été retirée et comportant uniquement l'ustensile coupe-cigares de la présente invention. The knife 1 generally comprises two lateral ribs, the more often covered with plastic, with internal faces appreciably flat and parallel, between which are arranged various utensils which can be extracted individually by pivoting or sliding in a plane parallel to the internal faces. The side ribs serve as a handle for the knife. For the simplicity of the drawing, the knife has been represented here as if one of the lateral ribs 18 had been removed and comprising only the cigar cutter of the present invention.

Le couteau est muni d'un coupe-cigares de type ciseau, c'est-à-dire comportant deux branches de ciseau 10, 11 pivotantes l'une par rapport à l'autre autour d'un premier axe 16. Les branches 10, 11 comportent chacune une portion de coupe courbée, le rayon de courbure correspondant au moins au rayon maximal des cigares usuels, par exemple 8 à 19 millimètres, sans dépasser toutefois des dimensions permettant de ranger les deux lames rapprochées comme sur la figure 2 dans le corps du couteau. Une portion de l'arête concave de chaque portion de coupe des deux branches 10, 11 est aiguisée, seul le biseau 113 de la seconde branche 11 étant visible sur les figures. L'arête convexe 114 de la portion de coupe de la branche 11 possède par ailleurs le même angle de courbure que l'extrémité 17 du couteau, en sorte que cette arête parvient exactement à fleur de ladite extrémité 17 lorsque le coupe-cigares est replié dans le couteau. La portion 114 se replie ainsi au-delà de l'axe (non représenté) de fixation d'ustensiles du côté opposé au coupe-cigares, ce qui permet de replier dans le couteau un coupe-cigares utilisant toute la longueur du couteau.The knife is fitted with a scissor-type cigar cutter, i.e. comprising two scissor arms 10, 11 pivoting one relative to the other around a first axis 16. The branches 10, 11 each have a curved section portion, the radius of curvature corresponding to at least at the maximum radius of usual cigars, for example 8 to 19 millimeters, without however exceed dimensions allowing the two blades to be stored close together as in Figure 2 in the body of the knife. A portion of the concave edge of each cutting portion of the two branches 10, 11 is sharpened, only the bevel 113 of the second branch 11 being visible on the FIGS. The convex edge 114 of the cutting portion of the branch 11 has otherwise the same angle of curvature as the end 17 of the knife, so that this edge reaches exactly flush with said end 17 when the cigar cutter is folded back into the knife. The portion 114 thus folds back beyond the axis (not shown) for fixing utensils on the side opposite the cigar cutter, which allows you to fold a cigar cutter using the knife the entire length of the knife.

Le coupe-cigares peut être extrait du couteau 1 en le faisant pivoter autour d'un axe 14 traversant la première branche de ciseau 10. Une lame de ressort 12 est également montée en rotation autour du même axe 14. La lame de ressort est disposée dans le même plan que la seconde branche de ciseau 11, en sorte que l'ensemble du coupe-cigares de l'invention ne revendique que deux largeurs de lame dans le couteau 1. Des moyens 15, 102 permettent d'entraíner la lame de ressort 12 avec la première branche de ciseau 10. Dans la forme de réalisation représentée, ces moyens sont constitués par un ergot 15 sur la branche 10, engagé dans une ouverture oblongue 102 dans la lame de ressort 12. Il est évident cependant que cette disposition pourrait tout aussi bien être inversée. La taille de l'ouverture 102 est suffisante pour permettre malgré tout un mouvement de rotation relatif de la lame de ressort 12 et de la branche 10 entre les deux positions illustrées sur les figures 1 et 2.The cigar cutter can be removed from knife 1 by rotating it around an axis 14 crossing the first chisel branch 10. A blade of spring 12 is also mounted for rotation about the same axis 14. The blade spring is arranged in the same plane as the second chisel branch 11, so that the whole cigar cutter of the invention claims only two blade widths in the knife 1. Means 15, 102 allow to drive the leaf spring 12 with the first chisel branch 10. In the embodiment shown, these means consist of a lug 15 on branch 10, engaged in an oblong opening 102 in the blade spring 12. It is clear, however, that this provision could just as easily well be reversed. The size of the opening 102 is sufficient to allow despite all a relative rotational movement of the leaf spring 12 and the branch 10 between the two positions illustrated in FIGS. 1 and 2.

Lorsque le coupe-cigares est extrait hors du couteau, une lame dorsale élastique 13, articulée autour d'un axe 130, vient en appui avec une portion 101 de la première branche 10 qu'elle repousse en position d'extraction maximale. La largeur de la lame dorsale 13 lui permet d'appuyer simultanément sur la lame de ressort 12, et de la maintenir dans la position intermédiaire illustrée sur la figure 1. Dans cette position intermédiaire, l'extrémité 120 de la lame de ressort 12 vient en appui contre une portion 110, 111 de l'arête dorsale de la deuxième branche 11. La position angulaire de la deuxième branche 11 autour de l'axe 16 est ainsi déterminée, lorsqu'aucune force externe n'est appliquée, par la disposition relative des moyens 110, 111, 120. En particulier, l'écartement des branches de ciseaux 10, 11 est limité par l'appui de la portion 120 de la lame 12 contre la surface d'appui 110 de la seconde branche 11. Lorsqu'aucune force externe n'est appliquée, la lame de ressort 12 maintient les branches 10, 11 extraites suffisamment écartées pour insérer l'extrémité du cigare, mais pas trop afin de pouvoir actionner le coupe-cigares tenu dans la main avec le pouce appuyé sur la poignée 112. Le coupe-cigares est ainsi directement prêt à l'utilisation lorsqu'on l'extrait hors du couteau.When the cigar cutter is pulled out of the knife, a blade elastic backbone 13, articulated around an axis 130, comes to bear with a portion 101 of the first branch 10 which it pushes back into the extraction position Max. The width of the back blade 13 allows it to press simultaneously on the leaf spring 12, and keep it in the position intermediate illustrated in FIG. 1. In this intermediate position, the end 120 of the spring leaf 12 bears against a portion 110, 111 of the dorsal edge of the second branch 11. The angular position of the second branch 11 around the axis 16 is thus determined, when none external force is applied, by the relative arrangement of means 110, 111, 120. In particular, the spacing of the scissor arms 10, 11 is limited by the support of the portion 120 of the blade 12 against the bearing surface 110 of the second branch 11. When no external force is applied, the blade of spring 12 keeps the extracted branches 10, 11 sufficiently spaced apart to insert the end of the cigar, but not too much in order to be able to activate the cigar cutter held in the hand with the thumb resting on the handle 112. The cigar cutter is thus directly ready for use when extracted from the knife.

De façon remarquable, les moyens 110, 120 limitant l'écartement des branches agissent dans le plan de la branche mobile 11, au contraire des ciseaux habituels dont l'écartement est limité par des moyens de butée dans un autre plan, par exemple par des portions de butée sur une des branches limitant le pivotement de l'autre branche. Cette disposition avantageuse simplifie la fabrication des branches 10, 11, dont l'épaisseur de la portion extraite peut être constante à l'exception de la portion aiguisée, et limite l'épaisseur totale du coupe-cigares.Remarkably, the means 110, 120 limiting the spacing branches act in the plane of the movable branch 11, unlike usual scissors whose spacing is limited by stop means in a another plane, for example by abutment portions on one of the branches limiting the pivoting of the other branch. This advantageous arrangement simplifies the manufacture of branches 10, 11, the thickness of the portion extracted can be constant except for the sharpened portion, and limits the total thickness of the cigar cutter.

La force de rappel de la lame dorsale élastique 13 est transmise à la surface d'appui convexe 111 de la seconde branche 11 par l'intermédiaire de la lame de ressort 12. La force à appliquer sur l'extrémité 112 de la branche 11 pour rapprocher les branches 10,11 doit par conséquent être suffisante pour faire pivoter la lame de ressort 12 et repousser la lame dorsale 13 vers le bas, comme on le voit sur la figure 2. La pression exercée par la lame dorsale 13 sur la première branche 10 est alors diminuée, en sorte que celle-ci pivote également vers le haut. L'ampleur du déplacement de la branche 10 est cependant limitée par les moyens 15, 102. Cette disposition permet de rapprocher les branches 10, 11 en exerçant une force constante sur l'extrémité 112.The restoring force of the elastic dorsal blade 13 is transmitted to the convex bearing surface 111 of the second branch 11 by means of the leaf spring 12. The force to be applied to the end 112 of the branch 11 to bring the branches together 10,11 must therefore be sufficient to rotate the spring leaf 12 and push the back leaf 13 down, as seen in Figure 2. The pressure exerted by the dorsal blade 13 on the first branch 10 is then decreased, so that it pivots also up. The extent of movement of branch 10 is however limited by the means 15, 102. This arrangement makes it possible to bring the branches 10, 11 together by exerting a constant force on the end 112.

Le pivotement des deux branches au-delà du point illustré sur la figure 2, c'est-à-dire au-delà de la situation de rapprochement maximal des deux branches 10, 11, est empêché par l'extrémité 1120 de la poignée 112 de la seconde branche 11 qui vient en butée contre une portion 121 de la lame de ressort 12. On constate donc que la course de pivotement de la seconde branche 11 autour de l'axe 16 est limitée uniquement par les contacts entre les l'appui de la portion 120 de la lame 12 contre la surface d'appui 110 de la seconde branche 11. Lorsqu'aucune force externe n'est appliquée, la lame de ressort 12 maintient les branches 10, 11 extraites suffisamment écartées pour insérer l'extrémité du cigare, mais pas trop afin de pouvoir actionner le coupe-cigares tenu dans la main avec le pouce appuyé sur la poignée 112. Le coupe-cigares est ainsi directement prêt à l'utilisation lorsqu'on l'extrait hors du couteau.The pivoting of the two branches beyond the point illustrated on the Figure 2, that is to say beyond the situation of maximum approximation of two branches 10, 11, is prevented by the end 1120 of the handle 112 of the second branch 11 which abuts against a portion 121 of the blade spring 12. It can therefore be seen that the pivoting stroke of the second branch 11 around the axis 16 is limited only by the contacts between the the support of the portion 120 of the blade 12 against the bearing surface 110 of the second branch 11. When no external force is applied, the blade of spring 12 keeps the extracted branches 10, 11 sufficiently spaced apart to insert the end of the cigar, but not too much in order to be able to activate the cigar cutter held in the hand with the thumb resting on the handle 112. The cigar cutter is thus directly ready for use when extracted from the knife.

De façon remarquable, les moyens 110, 120 limitant l'écartement des branches agissent dans le plan de la branche mobile 11, au contraire des ciseaux habituels dont l'écartement est limité par des moyens de butée dans un autre plan, par exemple par des portions de butée sur une des branches limitant le pivotement de l'autre branche. Cette disposition avantageuse simplifie la fabrication des branches 10, 11, dont l'épaisseur de la portion extraite peut être constante à l'exception de la portion aiguisée, et limite l'épaisseur totale du coupe-cigares.Remarkably, the means 110, 120 limiting the spacing branches act in the plane of the movable branch 11, unlike usual scissors whose spacing is limited by stop means in a another plane, for example by abutment portions on one of the branches limiting the pivoting of the other branch. This advantageous arrangement simplifies the manufacture of branches 10, 11, the thickness of the portion extracted can be constant except for the sharpened portion, and limits the total thickness of the cigar cutter.

La force de rappel de la lame dorsale élastique 13 est transmise à la surface d'appui convexe 111 de la seconde branche 11 par l'intermédiaire de la lame de ressort 12. La force à appliquer sur l'extrémité 112 de la branche 11 pour rapprocher les branches 10,11 doit par conséquent être suffisante pour faire pivoter la lame de ressort 12 et repousser la lame dorsale 13 vers le bas, comme on le voit sur la figure 2.

The force to be applied to the end 112 of the branch 11 to bring the branches together 10,11 must therefore be sufficient to rotate the spring leaf 12 and push the back leaf 13 down, as seen in Figure 2. The pressure exerted by the dorsal blade 13 on the first branch 10 is then decreased, so that it pivots also up. The extent of movement of branch 10 is however limited by the means 15, 102. This arrangement makes it possible to bring the branches 10, 11 together by exerting a constant force on the end 112.

Le pivotement des deux branches au-delà du point illustré sur la figure 2, c'est-à-dire au-delà de la situation de rapprochement maximal des deux branches 10, 11, est empêché par l'extrémité 1120 de la poignée 112 de la seconde branche 11 qui vient en butée contre une portion 121 de la lame de ressort 12. On constate donc que la course de pivotement de la seconde branche 11 autour de l'axe 16 est limitée uniquement par les contacts entre les surfaces 120 et 110, respectivement 121 et 1120, c'est-à-dire uniquement grâce à la lame de ressort 12 qui transmet en outre une force constante à la branche 11 quelle que soit sa position angulaire.The pivoting of the two branches beyond the point illustrated on the Figure 2, that is to say beyond the situation of maximum approximation of two branches 10, 11, is prevented by the end 1120 of the handle 112 of the second branch 11 which abuts against a portion 121 of the blade spring 12. It can therefore be seen that the pivoting stroke of the second branch 11 around the axis 16 is limited only by the contacts between the surfaces 120 and 110, respectively 121 and 1120, that is to say only thanks to the leaf spring 12 which also transmits a constant force to the branch 11 whatever its angular position.

Claims (3)

  1. Multifunctional pocket knife (1) comprising lateral sides (18) serving as a handle, the inner faces of the said lateral sides being substantially parallel, and at least one implement being able to pivot or slide in a plane parallel to the said inner faces of the lateral sides, one of the said implements consisting of a cigar cutter (10, 11, 12),
       characterised in that the said cigar cutter comprises two rounded scissor elements (10, 11) i.e. each comprising a portion of curved cut such as to allow the insertion of a cigar, which scissor elements are pivoting one with respect to the other about a first axis (16), one end of the first scissor element (10) being pivoting about a second axis (14) enabling it to be pulled out of the said knife.
  2. Knife according to claim 1, further comprising a spring blade (12) allowing the said scissor elements (10, 11) to be kept spaced apart when they are pulled out of said knife, this knife being characterised in that it further comprises an elastic back blade (13) acting upon the said first scissor element (10) to keep it either in a position retracted into the said knife or in a position completely pulled out of the knife, and acting simultaneously upon the said spring blade (12) so that the latter keeps the said scissor elements (10, 11) spaced apart, the second scissor element (11) comprising a resting surface (111) against the said spring blade (12) whose shape is determined in such a way that the force to be exerted to close the said scissor elements (10, 11) is substantially constant.
  3. Knife according to one of the claims 1 or 2, characterised in that the back edge (114) of the said second scissor element (11) has the same angle of curvature as the end (17) of the knife so as to enable the said second scissor element to be folded back into the said knife with the said back edge (114) flush with the said knife end.
