Description

La présente invention concerne un dispositif de coupe à lame rétractable comportant une lame et un manche dans lequel elle est susceptible de se rétracter.The present invention relates to a retractable blade cutting device with a blade and a handle in which it is likely to retract.

Des dispositifs de coupe à lame rétractable comportant une lame coulissant dans un manche à glissière sont bien connus. Par exemple des instruments de ce type appelés cutter, permettent de couper le papier, le carton ou tout autre matériau généralement sous forme de feuilles ou de plaques.Retractable blade cutters having a blade sliding in a slide handle are well known. For example instruments of this type called cutter, allow cutting the paper, cardboard or any other material generally in the form of sheets or plates.

Les lames utilisées dans ces dispositifs sont très aiguisées pour assurer une coupe efficace et elles sont généralement interchangeables afin de conserver un instrument parfaitement opérationnel. Ainsi, ces instruments sont relativement dangereux et de nombreux accidents interviennent pendant l'utilisation. De façon habituelle, l'utilisateur doit exercer une forte pression sur le manche de l'instrument et lui imprimer un déplacement rapide pour obtenir une coupe franche du matériau à découper. De la sorte lorsque le contact de la lame avec le matériau cesse, l'utilisateur doit également cesser de déplacer ledit instrument avec autant d'énergie que celle qui est nécessaire pour la découpe. Or généralement, les accidents interviennent lorsque le contact de la lame avec le matériau cesse et qu'emporté dans son élan, l'utilisateur porte l'instrument contre lui.The blades used in these devices are very sharp to ensure effective cut and they are generally interchangeable in order to keep a perfectly functioning instrument. Thus, these instruments are relatively dangerous and many accidents occur during use. In the usual way, the user must exert a strong pressure on the handle of the instrument and print it a quick move for obtain a clean cut of the material to be cut. In this way when the blade contact with the material ceases, the user must also stop to move the instrument with as much energy as necessary for cutting. In general, accidents occur when the contact of the blade with the material ceases and that carried in its momentum, the user wears the instrument against him.

Un problème qui se pose et que vise à résoudre la présente invention est alors de réaliser un dispositif de coupe à lame rétractable ou la lame se rétracte dans le manche avant que l'utilisateur maladroit ne porte le dispositif contre lui ou contre tout autre personne. A problem that arises and that aims to solve the present invention is then to achieve a retractable blade cutting device or the blade is retracts into the sleeve before the clumsy user wears the device against him or against any other person.

Par US 6 148 520 on connaít un cutter de sécurité à lame rétractable automatiquement lorsqu'elle cesse d'être en contact avec le produit en cours de coupe.By US 6 148 520 is known a safety knife retractable blade automatically when it stops being in contact with the product being cut.

A cet effet, dès que la lame est engagée dans le produit à couper et qu'une traction est exercée sur le cutter, un léger déplacement relatif de la lame par rapport au corps du cutter libère la lame qui sera ramenée automatiquement dans le corps du cutter par un dispositif de rappel à ressort dès que la lame quitte le produit qui vient d'être coupé.For this purpose, as soon as the blade is engaged in the product to be cut and a traction is exerted on the cutter, a slight relative displacement of the blade relative to the body of the cutter releases the blade which will be automatically brought back into the body of the cutter by a spring return device as soon as the blade leaves the product that has just been cut.

L'invention propose des moyens différents mettant en oeuvre une cinématique différente de rappel automatique de la lame dans sa position de rétraction dans le corps du cutter.The invention proposes different means implementing a kinematic different automatic return of the blade in its retracted position in the body of the cutter.

A cet effet, l'invention a pour objet un dispositif de coupe à lame rétractable comportant une lame et un manche dans lequel elle est susceptible de se rétracter, comprenant :

  • des moyens supports de lame, présentant des moyens formant butée d'entraínement, susceptibles de coulisser selon l'axe dudit manche entre une première position de repos où la lame est rétractée et une première position de travail où la lame est en extension en dehors dudit manche, lesdits moyens supports étant, dans ladite première position de travail, susceptibles d'être portés d'une seconde position de repos à une seconde position de travail, écartée de l'axe M dudit manche, en passant par une seconde position intermédiaire ;
  • des premiers moyens de rappel élastiques susceptibles de maintenir lesdits moyens supports de lame dans ladite première position de repos ;
  • des moyens de déplacement commandables montés sur ledit manche, susceptibles de coopérer avec lesdits moyens supports et à prendre appui contre lesdits moyens formant butée d'entraínement pour entraíner lesdits moyens supports de lame de ladite première position de repos vers ladite première position de travail ;
  • des moyens d'appui susceptible de recevoir lesdits moyens supports de lame dans ladite seconde position de travail pour les bloquer en translation ;
  • et dans lequel l'entraínement de la lame au moyen dudit manche contre une surface à découper entraíne lesdits moyens supports dans ladite seconde position de travail et provoque le désengagement desdits moyens de déplacement commandables engagés dans lesdits moyens formant butée d'entraínement de façon que lesdits moyens de rappel élastiques entraínent lesdits moyens supports de lame dans ladite première position de repos dès que la lame n'est plus en contact avec ladite surface et que lesdits moyens d'appui libèrent lesdits moyens supports de lame qui sont portés de ladite seconde position de travail vers ladite seconde position intermédiaire,
  • caractérisé en ce que lesdits moyens formant butée d'entraínement sont constitués de deux moyens formant ergot disposés sur les faces latérales d'une partie intermédiaire desdits moyens supports de lame, dans la partie inférieure de cette dernière et dont la surface d'appui est sensiblement perpendiculaire auxdits moyens supports.
To this end, the subject of the invention is a retractable blade cutting device comprising a blade and a handle in which it is capable of retracting, comprising:
  • blade support means, having means forming a drive abutment, slidable along the axis of said shaft between a first rest position where the blade is retracted and a first working position where the blade is extended outside said sleeve, said support means being, in said first working position, capable of being raised from a second rest position to a second working position, spaced apart from the axis M of said handle, passing through a second intermediate position;
  • first elastic return means capable of holding said blade support means in said first rest position;
  • controllable displacement means mounted on said handle, capable of cooperating with said support means and bearing against said means forming a drive abutment for driving said blade support means from said first rest position to said first working position;
  • bearing means capable of receiving said blade support means in said second working position to block them in translation;
  • and in which the drive of the blade by means of said handle against a surface to be cut causes said support means in said second working position and causes the disengagement of said controllable displacement means engaged in said means forming a drive abutment so that said resilient return means causes said blade support means in said first rest position as soon as the blade is no longer in contact with said surface and said support means releases said blade support means which are carried from said second position of working towards said second intermediate position,
  • characterized in that said means forming a drive abutment are constituted by two lug-forming means arranged on the lateral faces of an intermediate portion of said blade support means, in the lower part thereof and whose bearing surface is substantially perpendicular to said support means.

Selon une particularité avantageuse, lesdits moyens de déplacement commandables présentent une première partie faisant saillie hors du manche pour les commander, et une seconde partie se divisant en deux branches symétriques en regard l'une de l'autre, susceptible de chevaucher la partie supérieure desdits moyens supports de lame au moins dans ladite partie intermédiaire et l'extrémité portant la lame desdits moyens supports de lame, les branches étant susceptibles de prendre appui sur les surfaces d'appui des moyens formant ergot. De la sorte, lorsque les moyens de déplacement commandables sont entraínés en translation, les branches s'appuient contre les moyens formant ergot et entraínent les moyens supports de lame vers ladite première position de travail dans laquelle la lame est sortie du manche. According to an advantageous feature, said controllable displacement means have a first part protruding out of the handle to control them, and a second part dividing into two symmetrical branches facing one another, capable of overlapping the upper part of said blade support means at least in said intermediate portion and the end bearing the blade of said support means blade, the branches being able to bear on the bearing surfaces of ergot forming means. In this way, when the controllable displacement means are driven in translation, the branches rest against the means forming ergot and drive the blade support means to said first working position in which blade is out of the handle.

On comprend que la seconde partie des moyens de déplacement commandables, doit nécessairement permettre le passage de la première extrémité des moyens supports de lame et a fortiori de la lame pour qu'ils se rétractent sous l'effet des moyens élastiques lorsque les moyens de déplacement sont maintenus en position de travail.It is understood that the second part of the moving means commandably, must necessarily allow the passage of the first end of the blade support means and a fortiori the blade for them to retract under the effect of the elastic means when the means of movement are kept in working position.

Préférentiellement, lesdites branches de ladite seconde partie desdits moyens de déplacement commandables sont inclinées l'une par rapport à l'autre et par rapport à un plan de symétrie qui les sépare, et les parois latérales de ladite partie supérieure de ladite partie intermédiaire constituent des zones de frottement contre lesquelles les branches sont susceptibles de s'appliquer pour s'écarter l'une de l'autre lorsque lesdits moyens supports de lame sont entraínés vers lesdits moyens de déplacement commandables, et de se désengager desdits moyens formant ergot. Ainsi, la seconde partie des moyens de déplacement commandables forme une fourchette évasée dont la paroi interne des branches, au moins dans leur position médiane, vient en appui contre les parois latérales supérieures de la partie intermédiaire. En outre, l'extrémité des branches est susceptible d'être engagée dans les moyens formant butée d'entraínement situés dans la partie inférieure de la partie intermédiaire, lorsque les moyens supports de lame sont dans la première position de travail. De la sorte, le déplacement des moyens supports de lame, sensiblement perpendiculaire à leur axe longitudinal et vers le sommet de la fourchette où les branches se rejoignent provoque l'écartement des branches de la fourchette et la libération des moyens formant ergot. Cette situation se produit dès que l'on applique la lame contre la surface à découper après avoir entraíné les moyens de déplacement commandables et par conséquent les moyens supports de lame. Ces derniers étant alors portés dans ladite seconde position de travail. Preferably, said branches of said second part of said controllable displacement means are inclined relative to the other and with respect to a plane of symmetry that separates them, and the walls side of said upper part of said intermediate part constitute areas of friction against which the branches are likely to apply to deviate from each other when said medium supports blade are driven to said controllable displacement means, and disengage said ergot means. Thus, the second part of controllable means of displacement forms a flared fork whose inner wall of the branches, at least in their median position, comes into support against the upper side walls of the intermediate part. In In addition, the end of the branches is likely to be engaged in means forming a driving abutment located in the lower part of the intermediate part, when the blade support means are in the first working position. In this way, the displacement of the support means blade, substantially perpendicular to their longitudinal axis and towards the top of the fork where the branches meet causes spacing branches of the fork and the release of the ergot means. This situation occurs as soon as one applies the blade against the surface to be cut after having driven the means of displacement controllable and by therefore the blade support means. These latter being then worn in said second working position.

Selon une particularité avantageuse, la seconde partie desdits moyens de déplacement commandables entre les branches desquels ladite partie supérieure de ladite partie intermédiaire est susceptible d'être engagée constitue lesdits moyens d'appui susceptibles de bloquer lesdits moyens supports de lame dans ladite seconde position de travail. Ainsi, lorsque la lame est appliquée contre la surface à découper et que les moyens de déplacement commandables sont maintenus dans leur position de travail, les parois latérales supérieures de la partie intermédiaire viennent s'encastrer entre les branches de la fourchette et les écartent, mais elles permettent également, comme on l'expliquera plus en détails dans la suite de la description, le blocage en translation des moyens supports de lame par rapport aux moyens de déplacement commandables.According to an advantageous feature, the second part of said means controllable movements between the branches from which that part upper part of said intermediate part is likely to be engaged constitutes said support means capable of blocking said means blade supports in said second working position. So when the blade is applied against the surface to be cut and that the moving means controllable are held in their working position, the walls upper side of the intermediate part are embedded between the branches of the fork and spread them apart, but they also allow, as will be explained in more detail later in the description, the locking in translation of the blade support means relative to the means controllable displacement.

On comprend que lorsque l'application de la lame contre la surface à découper cesse, les branches de la fourchette tendent à se resserrer et à éloigner les moyens support de lame. De sorte que le blocage en translation cesse et que les moyens supports de lame sont pratiquement libres en translation.It is understood that when the application of the blade against the surface to cut, the branches of the fork tend to become narrower and move the blade support means away. So that the locking in translation ceases and that the blade support means are practically free in translation.

Avantageusement, lesdits premiers moyens de rappel élastiques sont constitués par un ressort hélicoïdal, qui entraíne les moyens supports de lame dans la position de repos lorsqu'ils sont libres par rapport à la fourchette.Advantageously, said first elastic return means are constituted by a helical spring, which causes the blade support means in the rest position when they are free from the fork.

De façon préférentielle, le dispositif comprend en outre des deuxièmes moyens de rappel élastiques susceptibles de maintenir lesdits moyens de déplacement commandables dans une position de repos.Preferably, the device further comprises second elastic return means capable of maintaining said means of displacement controllable in a rest position.

Selon un mode de réalisation avantageux, les moyens supports de lame et les moyens de déplacement commandables sont susceptibles d'être obtenus par moulage.According to an advantageous embodiment, the blade support means and the controllable displacement means are likely to be obtained by molding.

The blade holder 16 is slidable inside the sleeve 10 along its longitudinal axis A to remove the blade 12 to the open end 18 of the handle 10 and it is maintained in a first rest position, as illustrated in Figure 1, by a coil spring 19. In addition, the blade holder 16 has an intermediate portion 20 and a second guide end 22, allowing both the guidance in translation of the blade holder 16 and the maintenance of the blade 12 relative to the 10. To do this, the handle has a longitudinal housing 24, oriented towards the open end 18 of the handle 10, in which is inserted the blade holder 16 so as to guide it in translation.

Le dispositif de coupe comprend des moyens de déplacement commandables 26, présentant une première partie 28, ou curseur, faisant saillie hors du manche 10 et une seconde partie 30 se divisant en deux branches symétriques que l'on détaillera dans la suite de la description et qui chevauche la partie supérieure 32 du porte lame 16 pour s'étendre jusqu'au regard de la partie inférieure 34 du porte lame 16. Comme l'illustre la figure 1, dans cette position de repos, la seconde partie 30 est située au regard de la partie intermédiaire du porte lame 16. En outre, la partie inférieure 34 du porte lame 16 présente, dans la partie intermédiaire 20 des moyens formant butée d'entraínement 36 que l'on détaillera également dans la suite de la description.The cutting device comprises moving means controllable 26, having a first portion 28, or slider, protruding out of the handle 10 and a second portion 30 dividing in two symmetrical branches which will be detailed in the rest of the description and which overlaps the upper portion 32 of the blade holder 16 to extend to view of the lower portion 34 of the blade holder 16. As illustrated in FIG. in this rest position, the second part 30 is situated with regard to the intermediate portion of the blade holder 16. In addition, the lower portion 34 of the door blade 16 has, in the intermediate portion 20 means forming an abutment training 36 which will also be detailed in the following description.

Les moyens de déplacement commandables sont représentés, sur la figure 1, dans leur position de repos et ils sont susceptibles d'être déplacés parallèlement au manche 10 sur lequel ils sont montés et sensiblement parallèlement à l'axe longitudinal A du porte lame 16. Par ailleurs, ils sont maintenus dans leur position de repos par un ressort hélicoïdal 38.The controllable displacement means are represented on the Figure 1, in their rest position and they are likely to be moved parallel to the handle 10 on which they are mounted and substantially parallel to the longitudinal axis A of the blade holder 16. Moreover, they are held in their rest position by a helical spring 38.

On se référera maintenant à la figure 5 pour décrire les moyens de déplacement commandables 26. On retrouve sur cette figure les moyens de déplacement commandables 26 comportant la première partie 28 formant un curseur, susceptible d'être entraíné par les doigts de la main et la seconde partie 30 se divisant en deux branches symétriques 30a et 30b par rapport à un plan P et en regard l'une de l'autre. On comprend que la première partie 28 est située en dehors du manche 10 et que la seconde partie 30 est insérée dans le manche 10.Reference will now be made to FIG. 5 to describe the controllable displacement means 26. This figure shows the controllable displacement means 26 comprising the first portion 28 forming a slider, capable of being driven by the fingers of the hand and the 30 second part dividing into two symmetrical arms 30 a and 30 b relative to a plane P and facing each other. It is understood that the first portion 28 is located outside the handle 10 and the second portion 30 is inserted into the handle 10.

Les branches 30a et 30b présentent chacune une extrémité 39 et une portion médiane 40 et 42 inclinés l'une par rapport à l'autre et par rapport au plan P qui les sépare, de sorte que la seconde partie 30 forme une fourchette sensiblement évasée. En outre, les branches 30a et 30b sont élastiquement mobiles l'une par rapport à l'autre perpendiculairement au plan P et plus particulièrement, elles sont susceptibles d'être écartées l'une de l'autre et de retrouver leur position initiale lorsque la contrainte cesse. Cette caractéristique est obtenue en réalisant les moyens de déplacement commandables 26 en matière plastique, par exemple en polyamide.The branches 30 a and 30 b each have an end 39 and a middle portion 40 and 42 inclined relative to each other and relative to the plane P which separates them, so that the second portion 30 forms a substantially fork flared. In addition, the branches 30 a and 30 b are resiliently movable with respect to each other perpendicularly to the plane P and more particularly, they may be spaced apart from each other and return to their original position when the stress ceases. This characteristic is obtained by producing the controllable displacement means 26 made of plastic, for example polyamide.

Les moyens de déplacement commandables 26 coopèrent avec les moyens supports de lame 16 ou porte lame, que l'on retrouve illustrés en perspective sur la figure 6 et que l'on va maintenant décrire plus en détails.The controllable displacement means 26 cooperate with the blade support means 16 or blade holder, which are illustrated in FIG. perspective in Figure 6 and that will now be described in more detail.

La première extrémité, dépourvue de lame, se prolonge par la partie intermédiaire 20, elle-même prolongée par la seconde extrémité de guidage 22. La partie intermédiaire 20 comporte les moyens formant butée d'entraínement 36, situés dans la partie inférieure 34 de la paroi latérale du porte lame 16. Bien évidemment, des moyens formant butée d'entraínement 36 identiques sont situés de manière symétrique sur la paroi latérale opposée. Sur la figure 6A, une vue de détail de dessous, illustre les moyens formant butée d'entraínement 36 solidaire de la partie intermédiaire 20 qui elle-même, est prolongée par la première extrémité 14. Les moyens formant butée 36 constituent un ergot dont la face d'appui 44 est sensiblement perpendiculaire à l'axe longitudinal A du support de lame 16. En outre, l'ergot 36 est situé contre la face latérale de la partie intermédiaire 20 à proximité du bord que la première extrémité 14 prolonge. De la sorte, la partie intermédiaire 20 présente une face latérale d'appui 46, contre laquelle la branche 30b de la seconde partie 30 des moyens de déplacement commandables est susceptible de s'appliquer.The first end, without blade, is extended by the intermediate portion 20, itself extended by the second guide end 22. The intermediate portion 20 comprises the means forming a drive abutment 36, located in the lower portion 34 of the Of course, identical drive abutment means 36 are symmetrically located on the opposite side wall. In FIG. 6A, a detail view from below, illustrates the means forming a drive abutment 36 integral with the intermediate portion 20 which itself is extended by the first end 14. The abutment means 36 constitute an ergot whose bearing face 44 is substantially perpendicular to the longitudinal axis A of the blade support 16. In addition, the lug 36 is located against the side face of the intermediate portion 20 near the edge that the first end 14 extends. In this way, the intermediate portion 20 has a lateral bearing face 46, against which the leg 30b of the second portion 30 of the controllable displacement means is applicable.

De façon totalement symétrique, par rapport au plan T de symétrie du porte lame 16, un ergot 36 et une face d'appui sont situés contre l'autre face latérale, n'apparaissant pas sur la figure 6.In a completely symmetrical manner, with respect to the plane T of symmetry of blade holder 16, a lug 36 and a bearing face are located against the other face side, not shown in Figure 6.

On a également représenté sur la figure 6 la seconde extrémité 22, qui prolonge la partie intermédiaire, avec un profil de type "IPE" de façon à la rigidifier et à faciliter le guidage. En outre, les parois latérales de ladite partie supérieure 32 de ladite partie intermédiaire 20 sont légèrement tronquées de façon à former des surfaces inclinées 48 symétriques par rapport au plan T, de chaque côté du porte lame 16. Ces surfaces inclinées 48 constituent des zones de frottement contre lesquelles les branches sont susceptibles de s'appliquer comme on l'expliquer dans la suite de la description en référence aux figures 7A et 7B.FIG. 6 also shows the second end 22, which prolongs the intermediate part, with a profile of the type "IPE" so as to stiffen and facilitate guidance. In addition, the side walls of said portion 32 of said intermediate portion 20 are slightly truncated by to form inclined surfaces 48 symmetrical with respect to the plane T, on each side of the blade holder 16. These inclined surfaces 48 constitute areas of friction against which the branches are likely to apply as explained in the rest of the description in reference Figures 7A and 7B.

On retrouve sur la figure 7A, le porte lame 16 en section droite au niveau des ergots 36, et les moyens de déplacement commandables 26 dont la seconde partie 30 coïncide avec le porte lame 16 en le chevauchant, dans une première position d'équilibre stable. On retrouve également sur cette figure, les surfaces inclinées 48 contre lesquelles viennent s'appliquer la paroi interne des portions médianes inclinées 40, 42 des branches 30a et 30b, et leur extrémité 39 qui s'applique sur les faces latérales d'appui 46. Dans cette position, comme on l'expliquera en référence à la figure 1, le bord de l'extrémité 39 des branches 30a et 30b est situé en regard des faces d'appui 44 des ergots 36. Ainsi, lorsque les moyens de déplacement commandables sont entraínés, les bords des extrémités 39 s'appliquent contre les faces d'appui 44 pour entraíner le porte lame 16.Figure 7A shows the blade holder 16 in cross-section at the lugs 36, and the controllable displacement means 26, the second portion 30 of which coincides with the blade holder 16 by overlapping it, in a first stable equilibrium position. . There are also in this figure, the inclined surfaces 48 which are applied against the inner wall of the inclined middle portions 40, 42 of the branches 30 a and 30 b, and its end 39 which is applied to the lateral support faces 46. in this position, as will be explained with reference to Figure 1, the edge of the end 39 of the branches 30 a and 30 b is located opposite the bearing faces 44 of the lugs 36. Thus, when the controllable displacement means are driven, the edges of the ends 39 are applied against the bearing faces 44 to drive the blade holder 16.

Dans une seconde position d'équilibre instable, telle qu'illustré sur la figure 7B et correspondant à une seconde position de travail conformément à la figure 3, le porte lame 16 est déplacé dans une direction F vers la première partie 28 des moyens de déplacement commandables 26, où se rejoignent les deux branches 30a et 30b.In a second unstable equilibrium position, as illustrated in FIG. 7B and corresponding to a second working position according to FIG. 3, the blade holder 16 is moved in a direction F towards the first portion 28 of the displacement means controllable 26, wherein join the two branches 30 a and 30 b.

De la sorte, les surfaces inclinées 48 sont entraínées contre les parois internes des portions médianes inclinées 40 et 42, et glisse en frottant contre elles en écartant les branches 30a et 30b puisque la largeur de la partie intermédiaire 20 est constante et que la fourchette formée par les branches 30a et 30b est évasée. Ainsi, l'extrémité 38 des branches 30a et 30b se décolle des faces latérales d'appui 46 de sorte que, les bords des extrémités 39 se désengagent des faces d'appui 44 des ergots 36 et le blocage en translation du porte lame 16 par rapport aux moyens de déplacement commandables 26 n'est plus assuré par la coopération des ergots 36 et des bords de l'extrémité 39 des branches 30a et 30b.In this way, the inclined surfaces 48 are driven against the inner walls of the middle inclined portions 40 and 42, and slides by rubbing against them by spreading the branches 30 a and 30 b, since the width of the intermediate portion 20 is constant and the fork formed by the branches 30 a and 30 b is flared. Thus, the end 38 of the branches 30 a and 30 b comes off the lateral bearing faces 46 so that the edges of ends 39 disengage from the bearing faces 44 of the lugs 36 and the locking in translation of the blade holder 16 with respect to the controllable movement means 26 is no longer ensured by the cooperation of lugs 36 and the edges of the end 39 of the branches 30 a and 30 b.

En revanche, comme on va l'expliquer, lorsque la force F de rapprochement entre le porte lame 16 et les moyens de déplacement commandables est suffisante, le porte lame 16 est bloqué en translation par les branches 30a et 30b dont la paroi interne des portions médianes 40, 42 bloque par frottement la partie intermédiaire 20 et donc, le déplacement longitudinal du porte lame 16.However, as will be explained, when the approximation force F between the blade holder 16 and the controllable moving means is sufficient, the blade holder 16 is locked in translation by the branches 30a and 30b, the inner wall of medial portions 40, 42 frictionally blocks the intermediate portion 20 and therefore the longitudinal displacement of the blade holder 16.

La figure 1 illustre le dispositif de coupe conforme à l'invention au repos. Le porte lame 16 est situé dans une première position de repos correspondant à une position dans laquelle la lame 12 est rétractée. Dans cette position, les moyens de déplacement commandables 26 sont également dans une position de repos. Et la position de la seconde partie 30 des moyens de déplacement commandables 26 par rapport au porte lame 16, est celle qui est représentée sur la figure 7A. Les extrémités 39 des branches 30a et 30b sont alors en appui contre les faces latérales d'appui 46 et leur bord est en regard des surfaces d'appui 44 des ergots 36.Figure 1 illustrates the cutting device according to the invention at rest. The blade holder 16 is located in a first rest position corresponding to a position in which the blade 12 is retracted. In this position, the controllable displacement means 26 are also in a rest position. And the position of the second part 30 of the controllable displacement means 26 with respect to the blade holder 16, is that shown in FIG. 7A. The ends 39 of the branches 30 a and 30 b are then bearing against the side faces of support 46 and edge faces of the bearing surfaces 44 of the lugs 36.

De la sorte, lorsque le curseur 28 est entraíné en translation selon l'axe du manche, comme illustré sur la figure 2, les bords des extrémités 39 des branches 30a et 30b prennent appui contre les surfaces d'appui 44 des ergots 36 et entraínent simultanément le support de lame 16 pour le porter dans une première position de travail où la lame est sortie du manche 10. Dans cette position, les ressorts hélicoïdaux 19, 38 sont portés en extension et exercent une force de rappel isostatique sur le porte lame 16 et sur les moyens de déplacements commandables 26, lesquels sont maintenus en position.In this way, when the slider 28 is driven in translation along the axis of the handle, as shown in Figure 2, the edges of ends 39 of the branches 30 a and 30 b are supported against the bearing surfaces 44 of the lugs 36 and simultaneously drive the blade support 16 to carry it into a first working position where the blade is out of the handle 10. In this position, the coil springs 19, 38 are extended and exert an isostatic restoring force on the door blade 16 and the controllable displacement means 26, which are held in position.

Cette première position de travail correspond à une seconde position de repos, et ce n'est que dans une seconde position de travail illustrée sur la figure 3 dans laquelle la lame 12 est appliquée contre la surface à découper que le découpage proprement dit a lieu.This first working position corresponds to a second position of rest, and this is only in a second working position illustrated on the FIG. 3 in which the blade 12 is applied against the surface to be cut that the actual cutting takes place.

Ainsi, lorsque l'on applique la lame 12 contre la surface à découper une force R s'exerce sur elle et par conséquent sur le porte lame 16 dont l'axe longitudinal A est écarté de l'axe du manche M. En conséquence, le porte lame 16 pivote légèrement par rapport à sa seconde extrémité 22 qui est en appui dans le manche 10 et la partie intermédiaire 20 du porte lame 16 est forcée contre les moyens de déplacement commandables 26, toujours maintenus en position, de sorte que les branches 30a et 30b sont écartées l'une de l'autre comme l'illustre la figure 7B. Ainsi, les bords des extrémités 39 se désengagent des surfaces d'appui 44 des ergots 36 et le support de lame 16 n'est plus maintenu en translation par les branches 30a et 30b. En revanche, comme on l'a expliqué précédemment la paroi interne des portions médianes 40, 42 bloque par frottement la partie intermédiaire 20 et donc, le déplacement longitudinal du porte lame 16. De la sorte, lors de la translation entre la seconde position de travail, simultanément, le porte lame 16 est libéré en translation par les bords des extrémités 39 qui coopèrent avec les ergots et bloqué en translation par les portions médianes inclinées 40 et 42 des branches 30a et 30b. Cette seconde position de travail est maintenue tant que la lame 12 est maintenue contre la surface à découper, et que le curseur 28 est maintenu en position.Thus, when the blade 12 is applied against the surface to be cut, a force R is exerted on it and consequently on the blade holder 16 whose longitudinal axis A is spaced from the axis of the handle M. As a result, the blade holder 16 pivots slightly relative to its second end 22 which is supported in the handle 10 and the intermediate portion 20 of the blade holder 16 is forced against the controllable displacement means 26, still held in position, so that the branches 30 a and 30 b are spaced apart from each other as shown in FIG 7B. Thus, the edges of ends 39 disengage from the bearing surfaces 44 of the lugs 36 and the blade holder 16 is no longer maintained in translation by the branches 30 a and 30 b. On the other hand, as explained above, the inner wall of the middle portions 40, 42 frictionally locks the intermediate portion 20 and thus the longitudinal displacement of the blade holder 16. In this way, during the translation between the second position of the work, simultaneously, the blade holder 16 is released in translation by the edges of ends 39 which cooperate with the pins and blocked in translation by the inclined middle portions 40 and 42 of branches 30 a and 30 b. This second working position is maintained as long as the blade 12 is held against the surface to be cut, and the slider 28 is held in position.

En revanche, dès que la lame 12 n'est plus en appui contre la surface à découper, le support de lame 16 n'est plus déplacé à force contre la paroi interne des portions médianes 40, 42, et il évolue de la seconde position de travail vers une seconde position intermédiaire du fait du rapprochement des branches 30a et 30b d'une vers l'autre. De la sorte les portions médianes 40, 42, ne bloquent plus en translation le support de lame 16 et les ergots 36 ne s'engagent pas dans les branches 30a et 30b. Ainsi, sous l'effet de la force de rappel produite par le ressort hélicoïdal 19, le support de lame est entraíné dans la première position de repos, telle que représentée sur la figure 4. Ainsi, bien que le curseur 28 soit maintenu en position, la lame est rétractée.On the other hand, as soon as the blade 12 is no longer supported against the surface to be cut, the blade support 16 is no longer forcibly displaced against the inner wall of the middle portions 40, 42, and it moves from the second position working to a second intermediate position due to the approximation of the branches 30 a and 30 b of one towards the other. In this way the middle portions 40, 42, do not block more translationally blade carrier 16 and the pins 36 do not engage the legs 30 a and 30 b. Thus, under the effect of the return force produced by the helical spring 19, the blade support is driven into the first rest position, as shown in FIG. 4. Thus, although the slider 28 is held in position , the blade is retracted.

La présente invention n'est pas limitée au mode de réalisation précédemment écrit. Selon un autre mode de réalisation particulier, les moyens supports de lame présentent des moyens formant fourchette et les moyens de déplacement commandables présentent une partie apte à coopérer avec lesdits moyens formant fourchette, et en particulier ils comportent des moyens formant ergot.The present invention is not limited to the embodiment previously written. According to another particular embodiment, the blade support means have fork means and controllable means of displacement present a part able to cooperate with said fork means, and in particular they comprise ergot forming means.
