Description

La présente invention concerne un outil pliant multifonction incluant un instrument à deux leviers dont le premier levier est constitué par les côtes de l'outil multifonction et dont le deuxième levier sert également à déplier et à replier ledit instrument.The present invention relates to a multifunctional folding tool including a two-lever instrument of which the first lever is made by the ribs of the multifunction tool and whose second lever serves also to unfold and fold said instrument.

Les outils pliants multifonction sont le plus souvent des couteaux de poches pliants dont le manche permet de loger la lame repliée ainsi qu'un ou plusieurs autres instruments remplissant des fonctions diverses tels que tire-bouchon, tournevis, décapsuleur, poinçon, ciseaux, etc. Tous ces instruments sont au moins partiellement repliés dans le manche de l'outil et peuvent être dépliés indépendamment l'un de l'autre suivant l'utilisation que l'on veut faire de l'outil.Multifunctional folding tools are most often knives folding pockets, the handle of which accommodates the folded blade as well that one or more other instruments fulfilling various functions such as corkscrew, screwdriver, bottle opener, punch, scissors, etc. All these instruments are at least partially folded in the neck of the tool and can be unfolded independently of each other according to the use we want to make of the tool.

Un type d'instruments couramment inclus dans les outils pliants, outre les lames de couteau, sont les instruments à deux leviers articulés actionnant par exemple des lames ou des mâchoires, tels que des ciseaux, des pinces, des sécateurs, etc. Il existe une multitude de modèles de tels instruments pliants, différant par leur fonction, leur taille, leur mécanisme de pliage et surtout leur confort d'utilisation.A type of instrument commonly included in folding tools, besides the knife blades, are the instruments with two articulated levers actuating for example blades or jaws, such as scissors, pliers, secateurs, etc. There are a multitude of models of such folding instruments, differing in function, size, mechanism folding and especially their comfort of use.

Le brevet US 6065213 décrit par exemple des ciseaux pliants intégrés à un outil de poche multifonctions dont le premier levier est constitué par le corps de l'outil et qui se déplient par rotation du deuxième levier par rapport au premier levier. Le mouvement de rotation du deuxième levier doit cependant être amorcé par une pression sur une petite oreille proche de l'axe de rotation. La petite taille de l'oreille oblige l'utilisation d'un ongle ou d'un outil fin pour amorcer le dépliage des ciseaux et sa position proche de l'axe de rotation demande l'application d'une force relativement importante pour la génération du moment de rotation nécessaire. Le dépliage risque en outre d'être accidentellement amorcé, par exemple lors du transport de l'outil avec d'autres outils ou de son rangement dans une poche ou dans un étui. De plus, lorsque les ciseaux sont dépliés, la position du deuxième levier n'est pas précisément déterminée. L'utilisateur doit donc s'assurer avant chaque utilisation que la position relative des deux leviers lui permette de saisir correctement les ciseaux. Un désavantage supplémentaire des ciseaux tels que décrit dans ce brevet est le mécanisme générant la force d'écartement des lames lors de l'utilisation des ciseaux. Il s'agit d'un mécanisme fragile et relativement compliqué, constitué d'une pièce en rotation actionnée par un ressort et appuyant contre une des deux lames.US Patent 6,065,213 describes, for example, folding scissors integrated into a multifunctional pocket tool whose first lever is formed by the body of the tool and which unfold by rotation of the second lever relative to the first lever. The rotational movement of the second lever must however be initiated by pressing a small ear close to the axis of rotation. The small size of the ear requires the use of a fingernail or a fine tool to initiate the unfolding of scissors and its position close to the axis of rotation requires application of relatively great force for the generation of the moment of rotation required. Unfolding also risks being accidentally started, for example when transporting the tool with other tools or its storage in a pocket or in a case. In addition, when the scissors are unfolded, the position of the second lever is not precisely determined. The user must therefore ensure before each use that the relative position of the two levers allows it to correctly grasp the scissors. An additional disadvantage of scissors as described in this patent is the mechanism that generates the force for spreading the blades when the use of scissors. It is a fragile and relatively complicated, consisting of a rotating part actuated by a spring and pressing against one of the two blades.

Le brevet EP-A1-714736 décrit un outil pliant à deux leviers dont la version préférentielle est un sécateur dont le premier levier est constitué par le manche de l'outil et qui se déplie et se replie par rotation du deuxième levier. La force d'écartement des lames est générée par des lames dorsales élastiques plus robustes que le mécanisme à ressort évoqué précédemment. Dans ce cas également, le dépliage du sécateur risque toutefois d'être accidentellement amorcé. De même, lorsque l'instrument est déplié, la position du deuxième levier n'est pas non plus précisément déterminée. L'utilisateur doit donc s'assurer avant chaque utilisation que la position relative des deux leviers lui permette de saisir correctement les ciseaux. Un autre désavantage de cet outil réside dans le mécanisme d'entraínement de la lame par le deuxième levier. En effet, la lame est entraínée par l'intermédiaire d'une goupille qui lui est perpendiculaire et qui est, lors de l'assemblage de l'outil, insérée dans un rail pratiqué dans le deuxième levier. Le montage de la goupille dans la lame nécessite donc une opération intermédiaire entre l'usinage de la lame et l'assemblage de l'outil, augmentant ainsi les coûts de production.Patent EP-A1-714736 describes a folding tool with two levers, the preferential version is a pruner whose first lever is made up by the handle of the tool and which unfolds and folds by rotation of the second lever. The blade spreading force is generated by blades elastic backbones more robust than the spring mechanism mentioned previously. In this case also, the unfolding of the pruning shears risks however, to be accidentally initiated. Likewise, when the instrument is unfolded, the position of the second lever is also not precisely determined. The user must therefore ensure before each use that the relative position of the two levers allows it to correctly grasp the scissors. Another disadvantage of this tool is the mechanism blade drive by the second lever. Indeed, the blade is driven by a pin perpendicular to it and which is, during the assembly of the tool, inserted in a rail made in the second lever. The mounting of the pin in the blade therefore requires a intermediate operation between the machining of the blade and the assembly of the tool, thereby increasing production costs.

Un des buts de la présente invention est de proposer un outil pliant multifonction incluant au moins un instrument à deux leviers dont le premier levier est constitué du manche de l'outil et dont le pliage et le dépliage peuvent se faire en agissant uniquement sur une poignée pratiquée à l'extrémité du deuxième levier.One of the aims of the present invention is to propose a tool multifunction folding device including at least one instrument with two levers, the first lever consists of the handle of the tool and whose folding and unfolding can be done by acting only on a handle made at the end of the second lever.

Un autre but de la présente invention est de proposer un outil pliant multifonction incluant au moins un instrument à deux leviers offrant une sécurité optimale contre toute ouverture ou fermeture involontaire, améliorant ainsi également le confort d'utilisation.Another object of the present invention is to provide a tool multifunction folding including at least one instrument with two levers offering optimal security against any involuntary opening or closing, thus also improving the comfort of use.

Un but supplémentaire de l'invention est de proposer un outil pliant multifonction incluant au moins un instrument à deux leviers dont la production nécessite un minimum de manutention.An additional aim of the invention is to propose a tool multifunctional folding device including at least one instrument with two levers, the production requires minimal handling.

Ces buts sont atteints par l'outil pliant tel que décrit dans la première revendication indépendante de la présente demande. L'instrument pliant à deux leviers inclut dans l'outil selon la présente invention se déplie et se replie aisément par l'actionnement d'une poignée pratiquée à l'extrémité de leur deuxième levier. La sécurité et le confort d'utilisation sont assurés par un mécanisme maintenant fermement le deuxième levier dans une première position de repos lorsque l'instrument est replié et dans une deuxième position de repos lorsque l'instrument est déplié. Toutes les pièces constituant l'instrument à deux leviers inclus dans la version préférentielle de l'outil selon la présente invention, à part les rivets, sont étampées à partir d'une tôle puis pliées pour certaines, permettant ainsi la production à moindre coût de pièces aux formes hautement élaborées.These goals are achieved by the folding tool as described in the first claim independent of this application. The folding instrument with two levers included in the tool according to this invention unfolds and folds easily by actuating a handle practiced at the end of their second lever. Safety and comfort are ensured by a mechanism holding the second lever in a first rest position when the instrument is folded and in a second rest position when the instrument is unfolded. All the parts making up the two-lever instrument included in the preferred version of the tool according to the present invention, apart from the rivets, are stamped from a sheet metal and then bent for some, thus allowing the production at low cost of shaped parts highly elaborate.

La présente invention sera mieux comprise à l'aide des figures 1 à 13 illustrant, à titre d'exemple explicatif mais non limitatif, la version préférentielle de l'invention. Dans cette version, l'outil pliant multifonction est un couteau de poche incluant un instrument à deux leviers constitué de ciseaux pliants tels qu'illustrés dans les figures 1 à 13.The present invention will be better understood using FIGS. 1 to 13 illustrating, by way of explanatory but nonlimiting example, the version preferential of the invention. In this version, the multifunctional folding tool is a pocket knife including a two-lever instrument consisting of folding scissors as illustrated in figures 1 to 13.

Le couteau de poche selon la version préférentielle de la présente invention possède deux côtes dont la périphérie 10 est représentée en traitillé sur les figures 2 à 13, constituant le manche du couteau et définissant un espace intermédiaire à l'intérieur duquel se replient au moins partiellement tous les instruments disponibles. Une lame de couteau, les ciseaux pliants, un décapsuleur-tournevis et un ouvre-boíte peuvent par exemple être dépliés depuis la face frontale du couteau de poche. Sur le dos du couteau se trouvent encore par exemple un tire-bouchon et un poinçon.The pocket knife according to the preferred version of this invention has two ribs whose periphery 10 is shown in dashed in Figures 2 to 13, constituting the knife handle and defining an intermediate space inside which fold back to the at least partially all the instruments available. A knife blade, folding scissors, a bottle opener and a can opener can example be unfolded from the front of the pocket knife. On the back of the knife there is still for example a corkscrew and a punch.

Les ciseaux pliants occupent la partie centrale de l'espace intermédiaire. Deux éléments de séparation 1, 2 séparent les ciseaux des autres instruments et préviennent tout frottement lors de l'ouverture ou de la fermeture des ciseaux.Folding scissors occupy the central part of the space intermediate. Two separation elements 1, 2 separate the scissors from the other instruments and prevent any friction when opening or closing the scissors.

Les ciseaux sont constitués d'une première lame 3 pouvant pivoter autour d'un premier axe de rotation u par rapport au manche du couteau, le manche constituant le premier levier des ciseaux. Lorsque les ciseaux sont fermés (fig. 2), la première lame 3 est presque entièrement repliée dans l'espace intermédiaire. Lorsque les ciseaux sont ouverts (fig.6), la première lame 3 est dépliée dans la prolongation du premier levier formant ainsi avec ce dernier la première branche des ciseaux.The scissors consist of a first blade 3 which can pivot around a first axis of rotation u relative to the handle of the knife, the handle constituting the first lever of the scissors. When the scissors are closed (fig. 2), the first blade 3 is almost entirely folded in the intermediate space. When the scissors are open (fig. 6), the first blade 3 is unfolded in the extension of the first lever thus forming with the latter the first branch of the scissors.

Une deuxième lame 4 peut pivoter par rapport à la première lame 3 autour d'un deuxième axe de rotation v.A second blade 4 can pivot relative to the first blade 3 around a second axis of rotation v.

Un deuxième levier 5 peut pivoter par rapport à la première lame 3 et à la deuxième lame 4 autour du deuxième axe v. Le deuxième levier 5 et la deuxième lame 4 forment la deuxième branche des ciseaux lorsque ceux-ci sont ouverts. L'extrémité du deuxième levier est pliée de façon à former une poignée 50 servant à faciliter la saisie dudit deuxième levier 5 lors de la fermeture et de l'ouverture des ciseaux ainsi qu'à garantir à l'utilisateur un certain confort lors de leur actionnement.A second lever 5 can pivot relative to the first blade 3 and to the second blade 4 around the second axis v. The second lever 5 and the second blade 4 form the second branch of the scissors when these are open. The end of the second lever is folded so that form a handle 50 used to facilitate the gripping of said second lever 5 when closing and opening the scissors as well as guaranteeing the user a certain comfort during their actuation.

Un premier élément élastique, par exemple une première lame dorsale élastique 6 sert à maintenir la première lame 3 dans une première position fixe lorsque les ciseaux sont repliés (fig. 3) et dans une deuxième position fixe lorsque les ciseaux sont dépliés (fig. 7, fig. 11), tout en permettant la rotation de la première lame 3 autour du premier axe u lors de la fermeture et de l'ouverture des ciseaux. L'élasticité de la première lame dorsale élastique 6 est créée par sa fixation uniquement aux axes r et s. L'extrémité de la première lame dorsale élastique 6 appuyant contre la première lame 3 est laissée libre, permettant ainsi son mouvement sous l'effet d'une force dont l'intensité dépendra principalement du matériau utilisé et des dimensions de la lame dorsale.A first elastic element, for example a first blade elastic backbone 6 serves to hold the first blade 3 in a first fixed position when the scissors are folded (fig. 3) and in a second fixed position when the scissors are unfolded (fig. 7, fig. 11), while allowing the rotation of the first blade 3 around the first axis u during closing and opening the scissors. The elasticity of the first elastic dorsal blade 6 is created by its attachment only to the axes r and s. The end of the first elastic dorsal blade 6 pressing against the first blade 3 is left free, allowing its movement under the effect of a force whose intensity will mainly depend on the material used and dimensions of the dorsal blade.

Un deuxième élément élastique, par exemple une deuxième lame dorsale élastique 7 a pour fonction principale d'appliquer sur la deuxième lame 4 une force écartant les lames des ciseaux lorsque ceux-ci sont ouverts. L'élasticité de la deuxième lame dorsale élastique 7 est générée par sa fixation aux axes r et s, de la même façon que pour la première lame dorsale élastique 6. L'amplitude des mouvements de la deuxième lame dorsale élastique 7 est précisément limitée par une rondelle 70 placée autour du premier axe u et glissant dans une échancrure oblongue 73 de la deuxième lame dorsale élastique 7 lors de l'actionnement des ciseaux.A second elastic element, for example a second blade elastic backbone 7 has the main function of applying to the second blade 4 a force spreading the blades of the scissors when they are open. The elasticity of the second elastic dorsal blade 7 is generated by its attachment to axes r and s, in the same way as for the first blade dorsal elastic 6. The range of motion of the second blade elastic back 7 is precisely limited by a washer 70 placed around the first axis u and sliding in an oblong notch 73 of the second elastic dorsal blade 7 when actuating the scissors.

Une lame dorsale rigide 8 fixée aux axes r, s, t et u sert d'une part à définir une première position de repos précise du deuxième levier 5 lorsque les ciseaux sont fermés (fig.5) et une deuxième position de repos précise du deuxième levier 5 lorsque les ciseaux sont ouverts (fig. 9) et d'autre part à amorcer le mouvement de rotation du deuxième axe v autour du premier axe u lorsque le deuxième levier 5 est sorti desdites positions de repos en vue de la fermeture ou de l'ouverture des ciseaux.A rigid dorsal blade 8 fixed to the axes r, s, t and u serves on the one hand to define a first precise rest position of the second lever 5 when the scissors are closed (fig. 5) and a second rest position precise of the second lever 5 when the scissors are open (fig. 9) and on the other hand to initiate the rotational movement of the second axis v around the first axis u when the second lever 5 is out of said rest positions for closing or opening the scissors.

Le dos des ciseaux, c'est-à-dire le dos de l'espace intermédiaire compris entre les deux éléments de séparation 1 et 2, est entièrement fermé par les trois lames dorsales 6, 7, 8. De part et d'autre du dos des ciseaux, le couteau de poche comporte d'autres lames dorsales maintenant les autres instruments repliés ou dépliés.The back of the scissors, i.e. the back of the intermediate space between the two separating elements 1 and 2, is entirely closed by the three dorsal blades 6, 7, 8. On either side of the back of the scissors, the pocket knife has other back blades now other instruments folded or unfolded.

Un rivet 9 tient ensemble la première lame 3, la deuxième lame 4 et le deuxième levier 5 et permet leur rotation relative autour du deuxième axe v. Le rivet 9 comporte un méplat 90 sur la partie de sa longueur traversant la première lame 3 et la deuxième lame 4. Sur la première lame 3, l'orifice 34 dans lequel est inséré le rivet est de forme identique à la coupe du rivet à cet endroit, empêchant ainsi la rotation du rivet 9 par rapport à la première lame 3. L'orifice 44 de la deuxième lame 4 dans lequel est inséré le rivet possède une découpe supplémentaire 440 permettant une rotation limitée de la deuxième lame 4 autour du rivet 9, limitant ainsi précisément l'écartement des lames 3 et 4.A rivet 9 holds together the first blade 3, the second blade 4 and the second lever 5 and allows their relative rotation around the second axis v. Rivet 9 has a flat 90 on the part of its length crossing the first blade 3 and the second blade 4. On the first blade 3, the orifice 34 in which the rivet is inserted is of identical shape to the cut the rivet at this point, preventing rotation of the rivet 9 by relative to the first blade 3. The orifice 44 of the second blade 4 in which is inserted the rivet has an additional cutout 440 allowing limited rotation of the second blade 4 around the rivet 9, thus precisely limiting the spacing of the blades 3 and 4.

Quatre rivets non représentés et placés selon quatre axes r, s, t, u perpendiculaires au côtes 1, 2 servent à maintenir ensemble les éléments constituant les ciseaux pliants.Four rivets not shown and placed along four axes r, s, t, u perpendicular to the ribs 1, 2 serve to hold the elements together constituting the folding scissors.

Lorsque les ciseaux pliants sont fermés, la première lame 3 et la deuxième lame 4 se retrouvent presque entièrement dans l'espace intermédiaire défini par les côtes du couteau de poche (fig. 2). La première lame dorsale élastique 6 maintient la première lame 3 en position repliée (fig. 3) par l'appui de sa zone de contact 61 contre la première surface de contact 31 de la première lame 3. La rotation involontaire de la première lame 3 autour du premier axe u est ainsi empêchée par la force de la première lame dorsale élastique 6. La deuxième lame 4 étant liée à la première lame 3 par le rivet 9, elle se trouve également repliée dans l'espace intermédiaire défini par les côtes du couteau (fig. 4). Le deuxième levier 5 est maintenu dans sa première position de repos par l'action de la force de la première lame dorsale élastique 6 sur la première lame 3 qui, par l'intermédiaire du rivet 9, le plaque jusqu'à son appui contre la portion d'appui 83 de la lame dorsale rigide 8 et l'ajustement de sa première encoche 51 contre la première oreille 81 de la lame dorsale rigide 8 (fig. 5). Lorsque les ciseaux sont fermés et que, par conséquent, le deuxième levier 5 est replié dans sa première position de repos, la poignée 50 se trouve au-dessus des lames 2 et 3, facilitant ainsi sa saisie pour l'ouverture des ciseaux (fig. 2).When the folding scissors are closed, the first blade 3 and the second blade 4 are found almost entirely in space intermediate defined by the ribs of the pocket knife (fig. 2). The first one elastic back blade 6 keeps the first blade 3 in the folded position (Fig. 3) by pressing its contact zone 61 against the first surface of contact 31 of the first blade 3. The involuntary rotation of the first blade 3 around the first axis u is thus prevented by the force of the first elastic dorsal blade 6. The second blade 4 being linked to the first blade 3 by the rivet 9, it is also folded in the intermediate space defined by the ribs of the knife (fig. 4). The second lever 5 is held in its first rest position by the action of the force of the first elastic dorsal blade 6 on the first blade 3 which, via the rivet 9, the plate until it rests against the portion support 83 of the rigid dorsal blade 8 and the adjustment of its first notch 51 against the first ear 81 of the rigid dorsal blade 8 (fig. 5). When the scissors are closed and therefore the second lever 5 is folded back into its first rest position, the handle 50 is above blades 2 and 3, thus facilitating its entry for the opening of the scissors (fig. 2).

En tirant la poignée 50 avec une force opposée à la force exercée par la première lame dorsale élastique 6, le deuxième levier 5 entre en rotation autour du deuxième axe v et sort de sa première position de repos. L'appui de la première encoche 51 contre l'oreille 81 amorce la rotation de l'axe v autour du premier axe u, sortant également la première lame 3 et la deuxième lame 4 de leurs positions de repos respectives.By pulling the handle 50 with a force opposite to the force exerted by the first elastic dorsal blade 6, the second lever 5 enters rotation around the second axis v and leaves its first rest position. Pressing the first notch 51 against the ear 81 initiates the rotation of the v axis around the first u axis, also leaving the first blade 3 and the second blade 4 from their respective rest positions.

La continuation du mouvement de rotation du deuxième levier 5 provoque le dépliage complet des ciseaux grâce à l'entraínement de la deuxième lame 4 par le deuxième levier 5 qui appuie avec sa région d'actionnement 53 contre la barrette 43 de la deuxième lame 4. Durant le mouvement d'ouverture des ciseaux, les lames 3, 4 sont progressivement écartées sous l'effet de l'extrémité arrondie 75 de la deuxième lame dorsale élastique 7 agissant comme une came guidant le mouvement de la deuxième lame 4 avec laquelle elle est en contact. L'ouverture des ciseaux est achevée lorsque la première lame 3, entraínée par le deuxième levier 5 par l'intermédiaire de la deuxième lame 4 et du rivet 9, arrive en position dépliée (fig. 7).Continuation of the rotation movement of the second lever 5 causes the complete unfolding of the scissors thanks to the drive of the second blade 4 by the second lever 5 which presses with its region actuation 53 against the bar 43 of the second blade 4. During the opening movement of the scissors, the blades 3, 4 are gradually spread apart under the effect of the rounded end 75 of the second dorsal blade elastic 7 acting as a cam guiding the movement of the second blade 4 with which it is in contact. Opening the scissors is completed when the first blade 3, driven by the second lever 5 via the second blade 4 and the rivet 9, arrives in position unfolded (fig. 7).

Entre ces deux positions fixes, la deuxième lame 3 est freinée par la force de la première lame dorsale élastique 6 appuyant avec sa zone de contact 61 contre la partie arrondie 33 se trouvant entre les deux surfaces de contact planes 31 et 32. Ce mécanisme augmente la sécurité et le confort d'utilisation des ciseaux par le contrôle des mouvements d'ouverture et de fermeture dont toute position intermédiaire est stable.Between these two fixed positions, the second blade 3 is braked by the force of the first elastic dorsal blade 6 pressing with its zone of contact 61 against the rounded part 33 located between the two surfaces contact plates 31 and 32. This mechanism increases safety and comfortable use of scissors by controlling movements opening and closing in which any intermediate position is stable.

Lorsque les ciseaux sont ouverts, la première lame 3 est maintenue par la première lame dorsale élastique 6 qui appuie avec sa zone de contact 61 contre la deuxième surface de contact 32 de la première lame 3, empêchant ainsi sa rotation involontaire autour du premier axe u. La deuxième lame dorsale élastique 7 exerce alors sur la deuxième lame 4 une force la maintenant écartée de la première lame 3. Le deuxième levier 5 est maintenu dans sa deuxième position de repos par la force appliquée par la deuxième lame dorsale élastique 7 par l'intermédiaire de la deuxième lame 4 et du rivet 9. La deuxième position du deuxième levier 5 est déterminée par l'ajustement de la deuxième encoche 52 contre la deuxième oreille 82 de la lame dorsale rigide 8 (fig. 9). When the scissors are open, the first blade 3 is held by the first elastic dorsal blade 6 which presses with its contact zone 61 against the second contact surface 32 of the first blade 3, thus preventing its involuntary rotation around the first axis u. The second elastic dorsal blade 7 then exerts on the second blade 4 a force keeping it away from the first blade 3. The second lever 5 is held in its second rest position by the force applied by the second elastic dorsal blade 7 via the second blade 4 and rivet 9. The second position of the second lever 5 is determined by adjusting the second notch 52 against the second ear 82 of the rigid dorsal blade 8 (fig. 9).

Une fois ouverts, les ciseaux sont actionnés par l'exercice d'une force sur la poignée 50 ramenant le deuxième levier 5 vers le premier levier. Le deuxième levier 5 entraíne dans son mouvement la deuxième lame 4 par l'appui de sa région d'actionnement 53 contre la barrette 43 de la deuxième lame 4, agissant ainsi contre la force exercée par la deuxième lame dorsale élastique 7 sur la deuxième lame 4 en leur zone de contact 74, 45. Lorsque la pression sur la poignée 50 est relâchée, les lames 2 et 3 sont à nouveau écartées sous l'effet de la force de la deuxième lame dorsale élastique 7.Once opened, the scissors are activated by the exercise of a force on the handle 50 bringing the second lever 5 towards the first lever. The second lever 5 drives in its movement the second blade 4 by the support of its actuation region 53 against the bar 43 of the second blade 4, thus acting against the force exerted by the second elastic dorsal blade 7 on the second blade 4 in their contact zone 74, 45. When the pressure on the handle 50 is released, the blades 2 and 3 are at again pushed aside by the force of the second dorsal blade elastic 7.

Dans leur variante préférentielle, les ciseaux pliants selon la présente invention font usage de deux lames dorsales élastiques 6, 7 et une lame dorsale rigide 8. La première lame dorsale élastique 6 génère la force nécessaire au maintien des ciseaux dans leur position lorsqu'ils sont soit repliés, soit dépliés. La deuxième lame dorsale élastique 7 génère la force nécessaire au maintien des lames en position ouverte lorsque les ciseaux dépliés sont au repos ainsi que les forces nécessaires à l'écartement des lames 3, 4 lors de l'utilisation des ciseaux. La lame dorsale rigide 8 détermine les deux positions de repos de la deuxième branche 5 et amorce le mouvement de rotation du deuxième axe v autour du premier axe de rotation u. L'homme du métier comprendra que, pour remplir les mêmes fonctions de positionnement et de génération de force, il est parfaitement envisageable de modifier le nombre et la nature des lames dorsales ou d'utiliser d'autres mécanismes.In their preferred variant, the folding scissors according to the present invention make use of two elastic back blades 6, 7 and a rigid dorsal blade 8. The first elastic dorsal blade 6 generates the force necessary to keep the scissors in their position when they are either folded, or unfolded. The second elastic dorsal blade 7 generates the force necessary to keep the blades in the open position when the scissors unfolded are at rest as well as the forces necessary to spread the blades 3, 4 when using scissors. The rigid dorsal blade 8 determines the two rest positions of the second branch 5 and primer the rotational movement of the second axis v around the first axis of rotation u. Those skilled in the art will understand that, to complete the same positioning and force generation functions, it is perfectly possible to modify the number and the nature of the dorsal blades or to use other mechanisms.

Dans la version préférentielle des ciseaux pliants selon la présente invention, la première lame 3, la deuxième lame 4, le deuxième levier 5, la première lame dorsale élastique 6, la deuxième lame dorsale élastique 7 et la lame dorsale rigide 8 sont tous étampés à partir de tôles d'épaisseur soit identiques afin de faciliter la production, soit différentes afin d'ajuster l'élasticité des lames dorsales élastiques. La poignée 50 peut être formée, par exemple par pliage de l'extrémité du deuxième levier 5, par soudage d'une pièce métallique supplémentaire sur le deuxième levier 5 ou par surmoulage. La barrette 43 peut être formée par exemple par pliage de la deuxième lame 4 ou par brasage d'une goupille dans la deuxième lame 4. Les éléments de séparation 1, 2 sont étampés de préférence dans une tôle plus fine afin de limiter l'épaisseur des ciseaux pliants, limitant ainsi l'épaisseur du couteau de poche. Les opérations d'usinage décrites ci-dessus sont des opérations simples, réduisant ainsi les coûts de production des ciseaux pliants.In the preferred version of the folding scissors according to the present invention, the first blade 3, the second blade 4, the second lever 5, the first elastic dorsal blade 6, the second elastic dorsal blade 7 and the rigid dorsal blade 8 are all stamped from thick sheets either identical to facilitate production, or different to adjust the elasticity of the elastic back blades. The handle 50 can be formed, for example by folding the end of the second lever 5, by welding an additional metal part on the second lever 5 or by overmolding. The bar 43 can be formed for example by folding the second blade 4 or by brazing a pin in the second blade 4. The separating elements 1, 2 are preferably stamped in a sheet thinner to limit the thickness of the folding scissors, thus limiting the thickness of the pocket knife. The machining operations described above are simple operations, thereby reducing the production costs of folding scissors.

La version préférentielle de l'outil pliant multifonction selon l'invention incluant un instrument à deux leviers est constituée d'un couteau de poche incluant des ciseaux. Le principe de l'invention peut toutefois également s'appliquer à tout autre outil pliant incluant au moins un instrument à deux leviers actionnant des lames ou des mâchoires, tel que pinces, sécateurs, écarteurs, etc.The preferred version of the multifunction folding tool according to the invention including a two-lever instrument consists of a pocket knife including scissors. The principle of the invention can however also apply to any other folding tool including at least an instrument with two levers actuating blades or jaws, such such as pliers, pruning shears, spacers, etc.
