Abstract

The handle (1) of this screwdriver comprises a rear part (3) whose surface is smooth, and an intermediate part (4) and a front part (5) whose surface is made of a material, especially a flexible material, with relatively high coefficient of friction. <IMAGE>

Description

La présente invention est relative à un tournevis du type dont le manche comporte extérieurement une première zone en une matière lisse, notamment dure, et une seconde zone en une matière, notamment souple, à coefficient de frottement nettement supérieur à celui de la première zone, ce manche comprenant successivement une partie arrière de section relativement grande, une partie intermédiaire convergente vers l'avant, dont le tronçon arrière forme un bourrelet de liaison à la partie arrière, et une partie avant d'où émerge la lame du tournevis.The present invention relates to a screwdriver of the type whose handle externally comprises a first zone made of a smooth material, in particular hard, and a second zone made of a material, in particular flexible, with a coefficient of friction significantly greater than that of the first zone, this handle successively comprising a rear part of relatively large section, an intermediate part converging towards the front, the rear section of which forms a bead connecting to the rear part, and a front part from which the blade of the screwdriver emerges.

Dans les tournevis de ce type, la zone à frottement élevé a pour fonction d'améliorer la prise de l'outil lors du serrage/desserrage des vis, et également de permettre une manoeuvre précise du tournevis.In screwdrivers of this type, the function of high friction has the function of improving the grip of the tool when tightening / loosening the screws, and also of allowing precise operation of the screwdriver.

Toutefois, dans les solutions connues, l'agencement de la zone à frottement élevé gêne les mouvements d'avance rapide en début de vissage et de recul rapide en fin de dévissage, car elle est au contact de la paume de la main pendant que ces mouvements sont exécutés.However, in known solutions, the arrangement of the high friction zone impedes rapid advance movements at the start of screwing and rapid recoil movements at the end of unscrewing, since it is in contact with the palm of the hand while these movements are executed.

L'invention a pour but d'optimiser l'agencement des zones lisses et à frottement élevé de façon à faciliter non seulement la précision de manoeuvre et l'application de couples élevés, mais également les manoeuvres d'avance/recul rapides.The object of the invention is to optimize the arrangement of smooth and high friction zones so as to facilitate not only the precision of maneuver and the application of high torques, but also rapid advance / reverse maneuvers.

A cet effet, l'invention a pour objet un tournevis du type précité, caractérisé en ce que ladite première zone du manche s'étend sur sensiblement toute la partie arrière et sur une longueur au minimum du même ordre que le diamètre maximal du bourrelet, tandis que ladite seconde zone s'étend sur sensiblement toute la partie intermédiaire et sur sensiblement toute la partie avant, à l'exception éventuellement d'une partie d'extrémité avant du manche, chacune des deux zones s'étendant sur la totalité ou la quasi-totalité du pourtour du manche dans chacune des parties correspondantes de celui-ci.To this end, the subject of the invention is a screwdriver of the aforementioned type, characterized in that said first zone of the handle extends over substantially the entire rear part and over a length at least of the same order as the maximum diameter of the bead, while said second zone extends over substantially the entire intermediate portion and over substantially the entire portion front, with the possible exception of a front end portion of the handle, each of the two zones extending over all or almost all of the periphery of the handle in each of the corresponding parts thereof.

Suivant d'autres caractéristiques :

  • ladite seconde zone s'étend de façon continue sur toute sa longueur,
  • lesdites première et seconde zones s'étendent respectivement sur environ un tiers et environ deux tiers de la longueur du manche,
  • à l'exception éventuellement d'une partie d'extrémité avant du manche, la section d'aire maximale du manche se trouve au niveau dudit bourrelet, dans ladite seconde zone,
  • la partie arrière du manche comporte une extrémité sphérique s'étendant sur plus d'une demi-sphère, et un tronçon de liaison, notamment divergent vers l'avant, relié à cette extrémité sphérique,
  • le tronçon de liaison présente une section sensiblement polygonale, notamment carrée, à angles arrondis,
  • la partie sphérique se raccorde au tronçon de liaison par des arrondis à raccordements tangentiels,
  • l'ensemble du manche est dépourvu de toute arête, à l'exception éventuellement de gougeures longitudinales prévues sur la partie avant,
  • la partie avant du manche comporte, à partir de son extrémité avant, un tronçon à section croissante vers l'arrière, puis un tronçon à section décroissante vers l'arrière qui la relie à l'extrémité avant de la partie intermédiaire du manche.
According to other characteristics:
  • said second zone extends continuously over its entire length,
  • said first and second zones extend respectively over approximately one third and approximately two thirds of the length of the handle,
  • with the possible exception of a front end portion of the handle, the maximum area section of the handle is at the level of said bead, in said second zone,
  • the rear part of the handle has a spherical end extending over more than half a sphere, and a connecting section, in particular divergent towards the front, connected to this spherical end,
  • the connecting section has a substantially polygonal, in particular square, section with rounded angles,
  • the spherical part is connected to the connection section by rounds with tangential connections,
  • the entire handle is devoid of any edge, with the possible exception of longitudinal gougers provided on the front part,
  • the front part of the handle comprises, from its front end, a section with increasing section towards the rear, then a section with decreasing section towards the rear which connects it to the front end of the intermediate part of the handle.

Un exemple de réalisation de l'invention va maintenant être décrit en regard des dessins annexés, sur lesquels :

  • la Figure 1 représente en perspective un tournevis conforme à l'invention;
  • la Figure 2 représente en perspective, par des ensembles de lignes contenues d'une part dans des plans méridiens, d'autre part dans des plans perpendiculaires à l'axe, la forme du manche du tournevis de la Figure 1;
  • la Figure 3 est une vue analogue, mais de face, du manche du tournevis;
  • la Figure 4 est une vue analogue à la Figure 3, mais tournée de 45° autour de l'axe, du même manche;
  • les Figures 5 et 6 sont des sections transversales, prises suivant les lignes V-V et VI-VI, respectivement, de la Figure 3, montrant le contour de la section du manche à deux niveaux différents; et
  • la Figure 7 est une vue de dessus du tournevis, suivant la flèche VII de la Figure 3.
An embodiment of the invention will now be described with reference to the accompanying drawings, in which:
  • Figure 1 shows in perspective a screwdriver according to the invention;
  • Figure 2 shows in perspective, by sets of lines contained on the one hand in meridian planes, on the other hand in planes perpendicular to the axis, the shape of the handle of the screwdriver of Figure 1;
  • Figure 3 is a similar view, but from the front, of the handle of the screwdriver;
  • Figure 4 is a view similar to Figure 3, but turned 45 ° around the axis, of the same handle;
  • Figures 5 and 6 are cross sections, taken along lines VV and VI-VI, respectively, of Figure 3, showing the outline of the neck section at two different levels; and
  • Figure 7 is a top view of the screwdriver, along arrow VII of Figure 3.

Le tournevis représenté aux dessins est constitué d'un manche 1 d'où émerge une lame 2. Le manche 1 comprend trois parties, à savoir une partie arrière 3, une partie intermédiaire 4 et une partie avant 5.The screwdriver shown in the drawings consists of a handle 1 from which a blade emerges 2. The handle 1 comprises three parts, namely a rear part 3, an intermediate part 4 and a front part 5.

La partie arrière 3 comprend une extrémité arrière sphérique 6 s'étendant sur plus d'une demi-sphère, et un tronçon de liaison 7 légèrement divergent vers l'avant. Comme représenté sur les Figures 6 et 7, le tronçon 7 a, à chaque niveau, une forme grossièrement carrée à coins 8 fortement arrondis, avec des côtés qui sont rectilignes à l'extrémité avant, de plus grande section, de ce tronçon 7, et qui se creusent légèrement (Figure 6), de façon de plus en plus accentuée, en s'approchant de l'extrémité 6. Quatre évidements peu profonds 9 sont ainsi présents sur le tronçon 7.The rear part 3 comprises a spherical rear end 6 extending over more than half a sphere, and a connecting section 7 slightly diverging towards the front. As shown in FIGS. 6 and 7, the section 7 has, at each level, a roughly square shape with highly rounded corners 8, with sides which are rectilinear at the front end, of larger section, of this section 7, and which widen slightly (Figure 6), more and more accentuated, approaching the end 6. Four shallow recesses 9 are thus present on the section 7.

Comme on le voit sur la Figure 7, le cercle de plus grand diamètre de la sphère 6 est sensiblement inscrit dans le plus grand carré du tronçon 7.As seen in Figure 7, the larger diameter circle of sphere 6 is substantially inscribed in the largest square of section 7.

La partie intermédiaire 4 part de l'extrémité avant, de plus grande section, de la partie 3. Elle prolonge tout d'abord tangentiellement le tronçon 7 en formant un bourrelet 10 de liaison à profil convexe, qui comporte la section d'aire maximale du manche, puis présente une forme convergente sur tout le reste de sa longueur. La forme de sa section transversale passe progressivement de la forme grossièrement rectangulaire de l'extrémité avant du tronçon 7, qu'elle conserve le long du bourrelet 10, à une section circulaire. L'extrémité avant de la partie 4 représente la section d'aire minimale du manche 1. La longueur de la partie arrière 3 est supérieure au diamètre maximal du bourrelet 10 et représente environ un tiers de la longueur du manche.The intermediate part 4 starts from the front end, of larger section, of the part 3. It first tangentially extends the section 7 by forming a bead 10 of connection with convex profile, which comprises the section of maximum area of the handle, then has a converging shape over the rest of its length. The shape of its cross section gradually changes from the roughly rectangular shape of the front end of the section 7, which it keeps along the bead 10, to a circular section. The front end of part 4 represents the minimum area section of the handle 1. The length of the rear part 3 is greater than the maximum diameter of the bead 10 and represents approximately one third of the length of the handle.

La partie avant 5 possède une section circulaire. De l'arrière vers l'avant, son diamètre croît légèrement pour former un bourrelet avant 11 à profil arrondi, puis décroît progressivement, de façon sensiblement linéaire, jusqu'à l'extrémité avant 12 du manche. Un creux 13 est ainsi défini derrière le bourrelet 11, à la jonction des parties 4 et 5.The front part 5 has a circular section. From rear to front, its diameter increases slightly to form a front bead 11 with a rounded profile, then gradually decreases, in a substantially linear fashion, up to the front end 12 of the handle. A hollow 13 is thus defined behind the bead 11, at the junction of the parts 4 and 5.

Eventuellement, comme représenté sur la Figure 1, le dernier tronçon avant du manche peut être pourvu de gougeures peu profondes 14, définies par l'intersection de ce tronçon avec des cylindres d'axes parallèles à l'axe général X-X du tournevis.Optionally, as shown in Figure 1, the last front section of the handle may be provided with shallow gougers 14, defined by the intersection of this section with cylinders with axes parallel to the general axis X-X of the screwdriver.

La partie sphérique 6 est reliée au tronçon 7 par des arrondis 15 qui se raccordent tangentiellement des deux côtés. Tous les autres raccordements entre les parties successives du manche sont également tangentiels, de sorte que le manche ne comporte aucune arête, ce qui procure un grand confort d'utilisation.The spherical part 6 is connected to the section 7 by roundings 15 which are tangentially connected on both sides. All the other connections between the successive parts of the handle are also tangential, so that the handle has no edges, which provides great comfort in use.

Extérieurement, le manche 1 est réalisé en deux matières nettement différentes :

  • la surface de la partie arrière 3, de son extrémité arrière à son extrémité avant, est en une matière dure et lisse; et
  • la surface du reste du manche, c'est-à-dire des parties intermédiaire 4 et avant 5, est en une matière à coefficient de frottement relativement élevé, notamment en une matière souple telle qu'un élastomère.
Externally, the handle 1 is made of two clearly different materials:
  • the surface of the rear part 3, from its rear end to its front end, is made of a hard and smooth material; and
  • the surface of the rest of the handle, that is to say of the intermediate 4 and front 5 parts, is made of a material with a relatively high coefficient of friction, in particular of a flexible material such as an elastomer.

En cours d'utilisation du tournevis, la sphère 6 est en appui dans la paume de la main, avec éventuellement l'annuaire et/ou l'auriculaire repliés sur le tronçon 7 pour bien caler l'outil, et les trois doigts moteurs (pouce, index et majeur) agissent sur la partie avant 5 et éventuellement sur la partie intermédiaire 4. En fin de vissage et en début de dévissage, la main saisit fermement le manche, le majeur se serrant sur la partie intermédiaire 4, pour appliquer un couple élevé à l'outil.During use of the screwdriver, the sphere 6 is supported in the palm of the hand, possibly with the directory and / or the little finger folded over the section 7 to properly wedge the tool, and the three driving fingers ( thumb, index and middle finger) act on the front part 5 and possibly on the intermediate part 4. At the end of screwing and at the beginning of unscrewing, the hand grips the handle firmly, the middle finger tightening on the intermediate part 4, to apply a high tool torque.

Grâce à la structure superficielle bi-matière décrite ci-dessus, la partie du manche qui tourne au contact de la main, en phases d'avance rapide et de recul rapide, est entièrement dure et lisse, et donc tourne très librement sans provoquer d'échauffement de la peau, tandis que les trois doigts moteurs agissent en permanence sur une zone à frottement élevé. Lorsque ces trois doigts agissent sur la partie avant 5, une grande précision de manoeuvre est obtenue, et lorsqu'ils agissent également sur la partie intermédiaire 4 et que la paume de la main s'applique sur le bourrelet 10, un couple élevé peut être appliqué à l'outil.Thanks to the bi-material surface structure described above, the part of the handle which turns in contact with the hand, in rapid advance and rapid reverse phases, is entirely hard and smooth, and therefore rotates very freely without causing d heating of the skin, while the three motor fingers act permanently on an area with high friction. When these three fingers act on the front part 5, great maneuvering precision is obtained, and when they also act on the intermediate part 4 and the palm of the hand is applied to the bead 10, a high torque can be applied to the tool.

Il est à noter que le libre glissement de la partie arrière sur la main est encore favorisé par la forme de l'extrémité 6, qui tend à décoller la main du tronçon 7, tout en offrant à l'annulaire et/ou à l'auriculaire un appui arrière précis. De plus, la forme à peu près polygonale de la section du tronçon 7 améliore la prise du tournevis, notamment avec une main grasse.It should be noted that the free sliding of the rear part on the hand is further favored by the shape of the end 6, which tends to detach the hand from the section 7, while offering the ring finger and / or the ear precise back support. In addition, the roughly polygonal shape of the section of the section 7 improves the grip of the screwdriver, especially with an oily hand

Par ailleurs, le creux 13 formé à la jonction des parties 4 et 5 du manche assure un bon calage du majeur.Furthermore, the recess 13 formed at the junction of the parts 4 and 5 of the handle ensures good calibration of the middle finger.

Eventuellement, l'extrémité avant du manche peut être élargie en une garde 16 (Figure 3), laquelle peut posséder une section d'aire plus grande que celle du bourrelet 10 et/ou être superficiellement lisse.Optionally, the front end of the handle can be widened into a guard 16 (Figure 3), which can have a larger cross-sectional area than that of the bead 10 and / or be superficially smooth.
