Description

La présente invention est relative à une pince réglable à approche rapide manipulable à une main, suivant le préambule de la revendication 1.The present invention relates to a clamp Adjustable quick approach, manipulable with one hand, next the preamble of claim 1.

La technique actuelle des pinces réglables ou «multiprises» à approche rapide comprend deux catégories d'outils :

  • D'une part, des pinces manipulables à une seule main du type précité dont le moyen d'articulation ou doigt est normalement dégagé de la surface d'articulation, laquelle est généralement dentée. Un exemple est décrit dans le EP-A-218 760. Un inconvénient de ces pinces réside dans l'absence de mémorisation du point d'articulation, lequel ne peut être obtenu qu'en serrant un objet. Dès que le serrage est relâché, la pince revient en position grande ouverte, ce qui oblige l'opérateur à surmonter la force du ressort d'ouverture des mors à chaque utilisation. L'utilisation répétitive d'un tel outil est donc très fatigante.
  • D'autre part, des pinces, à doigt normalement en prise (voir par exemple le brevet US Des 297 802). Ces pinces mémorisent le point d'articulation, mais nécessitent les deux mains pour la phase d'approche. Il faut entendre par phrase d'approche, l'étape d'utilisation de la pince dans laquelle, en l'absence de contact des deux mors avec un objet à saisir, on exerce sur les poignées des efforts de directions adaptées tendant à rapprocher les mors.
The current technique of quick-approach adjustable pliers or "multi-pliers" includes two categories of tools:
  • On the one hand, manipulable forceps with one hand of the aforementioned type whose articulation means or finger is normally released from the hinge surface, which is generally toothed. An example is described in EP-A-218 760. A disadvantage of these clamps lies in the lack of memorization of the articulation point, which can be obtained only by tightening an object. As soon as the tightening is released, the clamp returns to the wide open position, which forces the operator to overcome the force of the opening spring of the jaws at each use. The repetitive use of such a tool is therefore very tiring.
  • On the other hand, pliers, normally engaged finger (see for example US Patent 297 802). These clamps memorize the point of articulation, but require both hands for the approach phase. By approach phrase is meant the step of using the clamp in which, in the absence of contact of the two jaws with an object to be grasped, the handles are exerted efforts of appropriate directions tending to bring the bit.

L'invention a pour but de fournir une pince réglable à approche rapide qui concilie les avantages des deux types de pince ci-dessus, c'est-à-dire qui, à la fois, soit manipulable à une seule main et mémorise le point d'articulation après réglage.The invention aims to provide an adjustable clamp fast approach that reconciles the benefits of both types above, that is, which, at the same time, is manipulated with one hand and memorizes the point articulation after adjustment.

A cet effet, l'invention a pour objet une pince du type précité, caractérisé par la partie caractérisante de la revendication 1. For this purpose, the subject of the invention is a gripper of aforementioned type, characterized by the characterizing part of the claim 1.

La pince suivant l'invention peut comporter une ou plusieurs des caractéristiques des revendications 2 à 19, prises isolément ou suivant toutes leurs combinaisons techniquement possibles.The clip according to the invention may comprise one or several of the features of claims 2 to 19, singly or in any combination technically possible.

La pince 1 représentée sur les Figures 1 à 5 est constituée des pièces suivantes :

  • une branche fixe 2 entrepassante, elle-même constituée de deux joues 3 et 4 en tôle d'acier découpée, d'un mors fixe ou supérieur 5, d'une entretoise arrière 6 de forme allongée et de rivets d'assemblage 7, deux de ces rivets étant représentés ;
  • une branche mobile 8 entrepassée, monobloc. Cette branche comporte à l'avant un mors mobile 9 venu de matière ;
  • un dispositif d'articulation 10 constitué d'un chariot 11, d'un doigt 12, d'un ressort 13 de sollicitation du doigt et de deux organes de fixation 14 et 15 ;
  • un ressort hélicoïdal 16 d'écartement des deux mors ; et
  • un coulisseau arrière 17, sollicité par un ressort hélicoïdal 18, dont le rôle apparaítra plus loin.
The clamp 1 shown in Figures 1 to 5 consists of the following parts:
  • a fixed branch 2 between, itself consisting of two cheeks 3 and 4 in cut steel sheet, a fixed or upper jaw 5, a rear spacer 6 of elongated shape and assembly rivets 7, two these rivets being represented;
  • a mobile branch 8 between, monobloc. This branch has at the front a movable jaw 9 come from matter;
  • a hinge device 10 consisting of a carriage 11, a finger 12, a spring 13 for biasing the finger and two fasteners 14 and 15;
  • a coil spring 16 spacing the two jaws; and
  • a rear slider 17, biased by a coil spring 18, whose role will appear later.

Chacune des joues 3 et 4 comporte une partie avant porte-mors 20, une région intermédiaire d'articulation 21, une région arrière de saisie 22 et, entre cette dernière et la région 21, une région d'appui arrière 23 pour la branche 8. Les deux régions arrière 22 forment la poignée fixe ou inférieure de la pince.Each of the cheeks 3 and 4 has a front portion jaw holder 20, an intermediate hinge region 21, a rearward gripping region 22 and, between the latter and region 21, a rear support region 23 for the branch 8. The two rear regions 22 form the fixed handle or lower part of the forceps.

La région 21 est arquée et comporte une lumière 24 elle-même arquée dont la surface supérieure 25 est lisse et dont la surface inférieure 26 est dentée et forme une crémaillère courbe. Les surfaces supérieure 27 et inférieure 28 de la région 21 ainsi que les surfaces 25 et 26 définissent quatre arcs de cercle concentriques dont le centre O (Figure 3) est virtuel et se trouve nettement à l'extérieur et au-dessus du contour de l'outil.Region 21 is arched and has a light 24 itself arcuate whose upper surface 25 is smooth and whose lower surface 26 is toothed and forms a curved rack. The upper surfaces 27 and lower 28 of the region 21 as well as the surfaces 25 and 26 define four concentric arcs of which the center O (Figure 3) is virtual and is clearly at outside and above the contour of the tool.

La région 23 est percée d'une lumière rectiligne 29 sensiblement dirigée vers le point O.Region 23 is pierced by a rectilinear light 29 substantially directed towards the point O.

Le mors supérieur 5 comporte un talon arrière 30 qui se positionne, grâce à une lumière 31A et à un épaulement 31B, sur des reliefs intérieurs 32A et sur une surface inférieure 32B des parties avant 20 des joues 3 et 4, comme décrit dans le FR-A-2 753 644. The upper jaw 5 has a rear heel 30 which is positioned, thanks to a light 31A and a shoulder 31B, on interior reliefs 32A and on a surface lower 32B of the front parts 20 of the cheeks 3 and 4, as described in FR-A-2 753 644.

L'entretoise 6 se positionne, grâce à des reliefs appropriés non représentés, entre la partie inférieure des deux régions 23 et entre les deux régions arrière 22. L'entretoise 6 présente un évidement supérieur 34 dans sa partie intermédiaire pour l'appui inférieur du ressort 18. Par ailleurs, le coulisseau 17 porte de chaque côté un relief 35 de forme allongée adapté pour être guidé dans la lumière 29 adjacente.The spacer 6 is positioned, thanks to reliefs not shown, between the lower part of the two regions 23 and between the two rear regions 22. The spacer 6 has an upper recess 34 in its intermediate part for the lower support of the spring 18. Moreover, the slider 17 carries on each side a relief 35 of elongated shape adapted to be guided in the adjacent light 29.

La branche entrepassée 8 comporte également, à partir de son mors 9, une région intermédiaire d'articulation 36, une région d'appui arrière 37 et une région arrière de saisie 38 formant poignée. Une encoche 39 ménagée dans la région 36 part du bord inférieur de la branche et se termine par un évidement 40 sensiblement en trois-quarts de cercle. Un renfoncement 41 est prévu dans la face arrière de l'encoche 39, tandis que la face avant de cette encoche présente un bossage 41A à l'entrée de l'encoche.The branch entered 8 also includes, from its jaw 9, an intermediate region articulation 36, a rear support region 37 and a rear gripping region 38 forming a handle. A notch 39 in the region 36 from the lower edge of the branch and ends with a recess 40 substantially in three quarters of a circle. A recess 41 is provided in the rear face of the notch 39, while the front face of this notch has a boss 41A at the entrance of the notch.

La région d'appui arrière 37 a une surface supérieure 42 sensiblement rectiligne, et sa partie arrière présente une surface inférieure active arquée 43, sensiblement en forme d'arc de cercle, dont le centre de courbure est virtuel et situé nettement en dehors et au-dessus du contour de l'outil. Ce centre peut être confondu avec le point O précité, ou voisin de celui-ci dans les différentes positions de la branche 8 pendant la phase d'approche décrite plus loin.The rear support region 37 has a surface upper 42 substantially rectilinear, and its rear portion has an arcuate active lower surface 43, substantially in the shape of an arc of a circle, whose center of Curvature is virtual and located clearly outside and above the contour of the tool. This center can be confused with the aforementioned point O, or a neighbor of it in the different positions of branch 8 during the phase approach described below.

Comme on le voit mieux sur la Figure 2, le chariot 11 est une pièce monobloc ayant la forme générale d'un U auquel est accolée une rondelle d'appui 44. Chaque aile du U comporte un évidement 45 sensiblement en trois- quarts de cercle, ces évidements étant coaxiaux et de même rayon que l'évidement 40 de la branche 8. Les surfaces supérieure 46 (qui s'étend sur toute la longueur du chariot) et inférieure 47 (qui ne s'étend qu'à l'avant des évidements 45) du U sont arquées suivant des rayons égaux à ceux des surfaces 25 et 26, respectivement, des lumières 24. La rondelle 44 est prévue sur une aile du U, tandis que l'autre aile porte un relief extérieur 48 en queue d'aronde traversé par l'évidement 45 adjacent.As best seen in Figure 2, the carriage 11 is a single piece having the general shape of a U to which is attached a support washer 44. Each wing of the U has a recess 45 substantially in three quarters of circle, these recesses being coaxial and of the same radius as the recess 40 of the branch 8. The upper surfaces 46 (which extends the entire length of the carriage) and lower 47 (which extends only to the front of the recesses 45) of the U are arcuate in radii equal to those of the surfaces 25 and 26, respectively, lights 24. The washer 44 is provided on one wing of the U, while the other wing carries a outer relief 48 dovetail crossed by the adjacent recess 45.

Le doigt 12 a la forme d'une plaquette perpendiculaire aux branches 2 et 8 et dont la surface inférieure est dentée en 49 à son extrémité arrière. L'extrémité avant du doigt forme un bourrelet cylindrique 50 adapté pour être reçu à pivotement dans les trois évidements 40 et 45, qui forment ensemble un palier.The finger 12 is in the form of a plate perpendicular to branches 2 and 8 and whose surface lower is toothed at 49 at its rear end. The front end of the finger forms a cylindrical bead 50 adapted to be pivotally received in the three recesses 40 and 45, which together form a landing.

Pour assembler la pince, on procède de la manière suivante :

  • le chariot 11 est introduit latéralement à travers la lumière 24 de la joue 4 jusqu'à ce que la rondelle 44 bute contre la face extérieure de la joue 4 ;
  • la branche 8 est glissée dans le U du chariot 11 ;
  • on met en coïncidence les axes des trois évidements 40 et 45 ;
  • on met en place le doigt 12 avec son bourrelet 50 dans ces évidements et avec compression du ressort 13 entre la partie courante du doigt et le fond du renfoncement 41 ;
  • on empile les pièces 5, 6 et 17, avec le ressort 18 comprimé entre le coulisseau 17 et l'évidement 34 de l'entretoise 6 ;
  • le ressort 16 est tendu entre un relief inférieur 51 prévu sur la branche 8 derrière l'encoche 39, et un orifice 52 du coulisseau 17 ;
  • on positionne la joue 3 sur l'ensemble ainsi monté, et on relie les pièces 3, 4, 5 et 6 par les rivets 7 ;
  • on termine l'assemblage du dispositif d'articulation 10 en emboítant la pièce 14, qui est une rondelle analogue à la rondelle 44, sur le relief en queue d'aronde 48 du chariot 11, puis on emmanche à force la pièce 15, qui est un bouton à tête, dans le trou central de la rondelle 14.
To assemble the clamp, proceed as follows:
  • the carriage 11 is introduced laterally through the slot 24 of the cheek 4 until the washer 44 abuts against the outer face of the cheek 4;
  • the branch 8 is slid into the U of the carriage 11;
  • the axes of the three recesses 40 and 45 are brought into coincidence;
  • the finger 12 is placed with its bead 50 in these recesses and with compression of the spring 13 between the current portion of the finger and the bottom of the recess 41;
  • the parts 5, 6 and 17 are stacked with the spring 18 compressed between the slider 17 and the recess 34 of the spacer 6;
  • the spring 16 is stretched between a lower relief 51 provided on the branch 8 behind the notch 39, and an orifice 52 of the slider 17;
  • the cheek 3 is positioned on the assembly thus mounted, and the parts 3, 4, 5 and 6 are connected by the rivets 7;
  • the assembly of the hinge device 10 is completed by fitting the part 14, which is a washer-like washer 44, on the dovetail relief 48 of the carriage 11, and then the part 15, which is a button with a head, in the central hole of the washer 14.

A l'état assemblé, chaque aile du U du chariot est alors guidée dans une lumière 24. Comme on le voit sur la Figure 6, le déplacement longitudinal de la branche mobile 8 est guidé par la seule coopération des ailes du chariot 11 et des lumières 24. Le doigt 12, qui possède une liberté de débattement limitée autour de l'axe A des évidements 40 et 45, est sollicité par le ressort 13 de manière à être normalement en prise par sa denture 49 dans les crémaillères 26.In the assembled state, each wing of the U of the carriage is then guided in a light 24. As we see on the Figure 6, the longitudinal displacement of the mobile branch 8 is guided by the only cooperation of the wings of the carriage 11 and lights 24. The finger 12, which has a freedom of limited clearance around the axis A of the recesses 40 and 45, is requested by the spring 13 so as to be normally engaged by its teeth 49 in the racks 26.

Pour une position déterminée du doigt 12 le long des lumières 24, l'axe A définit un axe d'articulation fixe de la branche 8 par rapport à la branche 2. Du fait de la sollicitation permanente des deux mors à l'écartement exercé par le ressort 16, la position de l'axe A est maintenue fermement, et l'outil s'utilise comme une pince classique, jusqu'à un degré prédéterminé d'ouverture angulaire des deux branches. Des opérations répétitives de saisie/relâchement d'un objet B peuvent donc être effectuées sans fatigue.For a determined position of the finger 12 along the lights 24, the axis A defines a fixed axis of articulation of branch 8 with respect to branch 2. Because of the permanent solicitation of the two jaws at the spacing exerted by the spring 16, the position of the axis A is maintained firmly, and the tool is used like a conventional forceps, up to a predetermined degree of angular opening of the two branches. Repetitive input / release operations of an object B can therefore be performed without fatigue.

On remarque que l'effort de serrage, au niveau de la région d'articulation, s'exerce uniquement par compression longitudinale du doigt 12 entre les crémaillères 26 de la branche 2 d'une part, le fond de l'évidement 40 de la branche 8 d'autre part, sans qu'aucun effort ne s'exerce sur le chariot 11. Celui-ci peut donc être réalisé en une matière légère, par exemple en matière plastique.Note that the clamping force, at the level of the region of articulation, exerted only by compression longitudinal finger 12 between the racks 26 of the branch 2 on the one hand, the bottom of the recess 40 of the branch 8 on the other hand, without any effort being exerted on the carriage 11. This can therefore be made in one light material, for example plastic.

Lorsque l'ouverture des deux branches amène le bossage 41A du bord avant des encoches 39 au contact du doigt 12, une ouverture supplémentaire de ces branches provoque positivement le dégagement de la denture 49 en comprimant le ressort 13, de sorte que, sous l'effet du ressort d'écartement 16, le chariot 11 recule.When opening the two branches brings the boss 41A of the front edge of the notches 39 in contact with the finger 12, an additional opening of these branches positively causes the clearance of the teeth 49 in compressing the spring 13, so that, under the effect of spacer 16, the carriage 11 moves back.

Cependant, comme illustré schématiquement à plus grande échelle sur la Figure 7, grâce à la forme arquée des lumières 24 et du fait de la longueur et de la disposition du doigt 12, il y a un décalage longitudinal entre les points d'appui avant 53 (appui indirect via le chariot 11) et arrière 54 (appui direct) du doigt sur les surfaces 25 et 26. Les tangentes T1 et T2 aux surfaces 25 et 26 aux points d'appui 53 et 54 sont sécantes en un point 55 situé à l'arrière du doigt. Par suite, lorsque le point d'appui arrière se dégage des surfaces 26, le doigt, guidé par le chariot seulement suivant la tangente T1, tend à se rapprocher des surfaces 26, et donc à revenir en prise avec celles-ci par sa denture arrière 49.However, as illustrated schematically at more large scale in Figure 7, thanks to the arcuate shape of lights 24 and because of the length and the layout finger 12, there is a longitudinal shift between points of support before 53 (indirect support via the carriage 11) and rear 54 (direct support) of the finger on the surfaces 25 and 26. Tangents T1 and T2 at surfaces 25 and 26 at points 53 and 54 are intersecting at a point 55 located at the back of the finger. As a result, when the fulcrum rear surfaces 26, the finger, guided by the trolley only following the tangent T1, tends to to approach surfaces 26, and thus to come back into contact with these by its rear teeth 49.

De plus, du fait de la courbure des lumières 24, il faut ouvrir de plus en plus les deux branches pour provoquer le dégagement du doigt lorsque celui-ci se déplace vers l'arrière desdites lumières. Par suite, le doigt, après s'être dégagé d'une dent, revient immédiatement en prise dans la dent suivante, ou dans une dent située plus légèrement en arrière, des crémaillères 26 sous l'effet du ressort 13.Moreover, because of the curvature of the lights 24, it must open more and more the two branches to provoke the release of the finger when it moves towards the back of said lights. As a result, the finger, after come off a tooth, immediately come back into action in the next tooth, or in a larger tooth slightly behind, racks 26 under the effect of spring 13.

On comprend ainsi que l'augmentation de l'écartement des deux mors 5 et 9 se contrôle, pratiquement cran à cran, avec une seule main, de préférence en disposant l'annulaire contre la face supérieure de la poignée de la branche 2 comme illustré sur la Figure 6.It is thus understood that the increase of the spacing of the two jaws 5 and 9 is controlled, practically notch to notch, with one hand, preferably by arranging the ring finger against the upper face of the handle of branch 2 as shown in Figure 6.

Pour réduire l'écartement des deux mors, comme illustré sur la Figure 8, on rapproche les deux poignées l'une de l'autre. Avant l'arrivée de la face arrière des encoches 39 au contact du doigt 12, la surface 43 de la branche 8 arrive au contact du coulisseau 17. Celui-ci est maintenu en position haute, avec butée de ses reliefs 35 à l'extrémité supérieure des lumières 29, par le ressort 18, lequel a une raideur relativement élevée. La géométrie des pièces est telle que la poursuite de l'effort de rapprochement des poignées provoque le glissement de la surface 43 sur le coulisseau et, simultanément, le coulissement vers l'avant du chariot 11 dans les lumières 24.To reduce the spacing of the two jaws, as shown in Figure 8, the two handles are one from the other. Before the arrival of the rear face of notches 39 in contact with the finger 12, the surface 43 of the branch 8 comes into contact with the slider 17. This is maintained in the high position, with stop of its reliefs 35 to the upper end of the lights 29, by the spring 18, which has a relatively high stiffness. The geometry of pieces is such that the continuation of the effort of approaching the handles causes the sliding of the surface 43 on the slider and, simultaneously, the sliding forward of the carriage 11 in the lights 24.

Ainsi, le chariot 11 et le coulisseau 17 forment ensemble un berceau qui guide la branche 8 vers l'avant suivant un mouvement sensiblement circulaire de centre O. Pendant ce mouvement, la branche mobile est guidée latéralement, à l'arrière, par coopération de sa région 37 et des joues 3 et 4. Au cours de ce déplacement, le doigt cliquette, et il se met en prise avec les dentures 26 dès que le mouvement cesse. Pendant cette phase d'approche, à chaque instant, les normales N1, N2 aux points de contact de la surface de guidage avant 25 et de la surface d'appui 43 forment un V d'angle légèrement inférieur à 90° ou, en variante, sensiblement égal à cette valeur, dont la pointe est dirigée vers le côté des branches opposé aux mors, c'est-à-dire vers le haut.Thus, the carriage 11 and the slider 17 form together a cradle that guides the branch 8 forward following a substantially circular motion of center O. During this movement, the mobile branch is guided laterally, at the rear, by cooperation of his region 37 and cheeks 3 and 4. During this move, the finger ratchet, and it engages with the teeth 26 as soon as that the movement ceases. During this phase of approach, each moment, the normals N1, N2 at the contact points of the front guide surface 25 and the support surface 43 form an angle V slightly less than 90 ° or, in variant, substantially equal to this value, whose peak is directed towards the side of the branches opposite the jaws, that is, upwards.

Pour obtenir une inclinaison des efforts F exercés sur les poignées qui facilite ce mouvement d'approche, la surface externe de la poignée supérieure est extérieurement convexe, et la poignée inférieure comporte à l'avant un évidement 56 de réception de l'index ou du majeur (Figure 8). En variante (Figures 10 et 12), la surface externe de la poignée inférieure peut être concave.To obtain an inclination of the exerted forces F on the handles that facilitates this approach movement, the outer surface of the upper handle is externally convex, and the lower handle has a front recess 56 receiving the index or major (Figure 8). Alternatively (Figures 10 and 12), the outer surface of the bottom handle can be concave.

Comme représenté sur la Figure 8, pendant cette phase d'utilisation de la pince, qui est la phase d'approche par rapport à un objet à saisir, la région 37, étant inférieurement bombée, provoque la flexion du ressort 16, au moins pour une certaine gamme d'écartement des mors. Par conséquent, lorsque la phase d'approche est terminée, comme illustré en traits mixtes sur la Figure 8, ce ressort 16 se redresse et confère à la branche 8 une position de repos légèrement ouverte, correspondant par exemple à la reprise d'un écrou. Ceci rend particulièrement agréable l'utilisation répétitive de la pince.As shown in Figure 8, during this phase of use of the clamp, which is the approach phase relative to an object to be seized, the region 37 being curved, causes the bending of the spring 16, less for a certain range of spacing of the jaws. By therefore, when the approach phase is over, as shown in phantom in Figure 8, this spring 16 is rectifies and confers on branch 8 a rest position slightly open, corresponding for example to the recovery of a nut. This makes it particularly pleasant the repetitive use of the clamp.

L'écrasement du ressort 18 permet d'exercer un sur-serrage de l'objet B, comme illustré sur la Figure 9. Il permet également d'assurer un bon engrènement des dents 26 et 49 même si, à l'issue de la phase d'approche, c'est-à-dire lorsque les deux mors arrivent au contact de l'objet B, les dents ne se trouvent par exactement en regard les unes des autres.The crushing of the spring 18 makes it possible to exert an over-tightening object B, as shown in Figure 9. It is also ensures a good meshing of the teeth 26 and 49 even if, at the end of the approach phase, that is to say when the two jaws come into contact with the object B, the teeth are exactly opposite each other others.

On remarque que l'espace situé entre les deux poignées de la pince est entièrement libre, ce qui réduit les risques de coincement des doigts de l'utilisateur.We note that the space between the two grips of the clamp is completely free, which reduces the risks of jamming the user's fingers.

Les Figures 10 et 11 représentent schématiquement un autre mode de réalisation de la pince suivant l'invention. Cette variante diffère essentiellement de la précédente par les moyens de guidage avant et arrière de la branche entrepassée 8.Figures 10 and 11 schematically represent a another embodiment of the clamp according to the invention. This variant differs essentially from the previous one by the front and rear guide means of the branch crossed 8.

D'une part, les lumières 24 sont rectilignes, comme dans les pinces à crémaillère classiques ; le chariot 11 est supprimé, et le doigt 12 est simplement monté librement rotatif sur un pion 57 solidaire de la branche 8.On the one hand, the lights 24 are rectilinear, as in conventional rack-and-pinion clamps; the cart 11 is deleted, and finger 12 is simply mounted freely rotating on a pin 57 secured to the branch 8.

D'autre part, le coulisseau 17 est remplacé par un bras 117 qui traverse l'espace situé juste à l'avant des deux poignées. L'extrémité inférieure de ce bras est pressée par un ressort 118 de raideur relativement élevée, suivant la direction générale de la branche 2, contre une butée 58 solidaire de cette branche. L'extrémité supérieure du bras 117 porte un téton transversal 59 dont les extrémités sont reçues dans des lumières de guidage 60 des joues 3 et 4. Ces lumières 60 ont une forme en S, avec une région supérieure 61 en arc de cercle centrée en 57, un épaulement oblique intermédiaire 62 et un prolongement vers le bas 63, décalé vers l'avant par rapport à la région 61.On the other hand, the slider 17 is replaced by a arm 117 that runs through the space just in front of two handles. The lower end of this arm is pressed by a spring 118 of relatively high stiffness, following branch 2, against a stop 58 in solidarity with this branch. The upper extremity of the arm 117 has a transverse nipple 59 whose ends are received in guide lights 60 of the cheeks 3 and 4. These 60 lights have an S shape, with a top region 61 in an arc centered in 57, an oblique shoulder intermediate 62 and an extension down 63, offset forward relative to region 61.

Par ailleurs, le ressort 16 d'écartement des mors est tendu à peu près perpendiculairement à la direction générale des deux branches, de façon à solliciter les deux branches et tendre à écarter les mors l'un de l'autre. Ce ressort est orienté judicieusement par rapport aux lumières et aux branches afin de solliciter en permanence le doigt en engagement dans les dentures 26.Moreover, the spring 16 for spacing the jaws is stretched roughly perpendicular to the direction the two branches, so as to solicit both branches and tend to spread the bits of one another. This spring is judiciously oriented in relation to the lights and to the branches to permanently solicit the finger in engagement in the teeth 26.

Le doigt 12 se trouvant dans une position donnée de prise avec les crémaillères 26 (Figure 10), la course morte du téton 59 dans la partie 61 des lumières 60 permet d'utiliser l'outil comme une pince classique, comme précédemment, c'est-à-dire d'ouvrir les mors sans changer de position d'articulation, le doigt restant en prise dans les crémaillères.The finger 12 being in a given position of taken with the racks 26 (Figure 10), the dead race of the nipple 59 in the part 61 of the lights 60 allows to use the tool as a classic forceps, as previously, that is to say to open the jaws without changing position of articulation, the finger remaining in racks.

La course morte est limitée, d'une part, par l'extrémité supérieure de la lumière 60, d'autre part, par l'épaulement oblique intermédiaire 62. Elle permet une reprise de pièce répétitive sans changement de point d'articulation.The dead race is limited, on the one hand, by the upper end of the light 60, on the other hand, by the intermediate oblique shoulder 62. It allows a repetitive play without change of point hinge.

Pour augmenter l'écartement des mors, on écarte les poignées l'une de l'autre jusqu'à amener le téton 59 en butée sur l'épaulement 62, ce que l'utilisateur ressent nettement, et on poursuit l'écartement des deux poignées.To increase the spacing of the jaws, we exclude handles from one another to bring the nipple 59 into stop on the shoulder 62, what the user feels clearly, and we continue the spacing of the two handles.

Le pion 64 vient alors en contact sur la face arrière de la partie intermédiaire de la branche 2 et devient un centre de pivotement de la branche 8, laquelle bascule jusqu'à ce que la denture 49 se dégage des dentures 26.The counter 64 then comes into contact on the face back of the middle part of branch 2 and becomes a center of rotation of the branch 8, which tilts until the teeth 49 emerge from the teeth 26.

Dans le même temps, le téton 59 poursuit sa course suivant la partie inférieure 63 de la lumière 60.At the same time, the nipple 59 continues its course following the lower portion 63 of the light 60.

Le ressort 16, par son orientation adaptée, écarte alors les mors vers leur position d'ouverture maximale. The spring 16, by its adapted orientation, departs then the jaws to their maximum open position.

Pour diminuer l'écartement des deux mors, à partir d'une position quelconque du doigt 12, on rapproche les poignées l'une de l'autre. Le bras 117 se comporte comme un bras articulé par son extrémité inférieure sur la branche 2, de sorte que le téton 59, en butée au sommet de la lumière 60, se déplace suivant un mouvement sensiblement circulaire, en comprimant de plus en plus le ressort 118, tandis que le pion 57 se déplace vers l'avant le long des lumières 24 en faisant cliqueter le doigt.To reduce the spacing of the two jaws, from of any position of the finger 12, we compare the handles from each other. The arm 117 behaves like a arm articulated by its lower end on the branch 2, so that the pin 59, abutting the top of the light 60, moves in a substantially circular motion, by compressing the spring 118 more and more, while the pawn 57 moves forward along the lights 24 into clicking the finger.

Dans ce mode de réalisation, on peut de nouveau régler d'une seule main l'ouverture de la pince. Toutefois, lorsqu'on dégage le doigt comme expliqué plus haut, sous l'effet du ressort 16 et du fait de la forme rectiligne des lumières 24, les mors ont tendance à reprendre instantanément leur position d'écartement maximal.In this embodiment, it is possible again adjust the opening of the clamp with one hand. However, when clearing the finger as explained above, under the effect of the spring 16 and because of the rectilinear shape of lights 24, the bits tend to resume instantly their position of maximum spacing.
