Le tournevis représenté aux. dessins, d'axe général X-X, est constitué de quatre pièces : une lame métallique 1, un noyau 2 en matière plastique rigide, un manchon 3 en matière plastique semi-rigide, et un pion de verrouillage 4. Ces pièces sont réalisées séparément puis assemblées mécaniquement .The screwdriver shown in. drawings, of general axis XX, consists of four parts: a metal blade 1, a core 2 of rigid plastic material, a sleeve 3 of semi-rigid plastic material, and a locking pin 4. These parts are produced separately and then mechanically assembled.
Dans ce qui suit, les mots « avant » et « arrière » se réfèrent respectivement aux côtés distal et proximal du manche, et aux côtés droit et gauche sur les Figures 1, 3, 5 et 7.In what follows, the words "front" and "rear" refer respectively to the distal and proximal sides of the handle, and to the right and left sides in Figures 1, 3, 5 and 7.
Le noyau 2 est un corps plein qui définit, d'avant en arrière : - une partie avant 5 de petit diamètre, sensiblement tronconique, qui converge vers l'arrière suivant un angle au sommet α petit, de l'ordre de' 0,2 à 1°, par exemple de 0,5°, et dont la tranche d'extrémité avant 6 est plane ; - une partie intermédiaire rainurée 7, comportant une région avant 8A convergente vers l'avant puis une région arrière cylindrique 8B, et dans laquelle sont prévues un certain nombre (six dans cet exemple) de rainures longitudinales cylindriques 9. Près de son extrémité arrière, la région 8B comporte un épaulement radial 10 qui forme un gradin de hauteur légèrement supérieure . Les parties 5 et 7 du noyau sont séparées par une gorge circulaire 11 à flanc avant radial et à flanc arrière convergent vers 1 ' avant ; et un pommeau arrière 12 de forme grossièrement hémisphérique, dont la face avant 13 est radiale et rejoint l'extrémité arrière de la région 8 et des rainures 9.The core 2 is a solid body which defines, from front to back: a front part 5 of small diameter, substantially frustoconical, which converges towards the rear at an apex angle α small, of the order of ' 0.2 to 1 °, for example 0.5 °, and whose front end edge 6 is flat; a grooved intermediate part 7, comprising a front region 8A converging towards the front then a cylindrical rear region 8B, and in which a number (six in this example) are provided of cylindrical longitudinal grooves 9. Near its rear end, the region 8B has a radial shoulder 10 which forms a step of slightly greater height. Parts 5 and 7 of the core are separated by a circular groove 11 with a radial front flank and a rear flank converging towards the front; and a rear knob 12 of roughly hemispherical shape, the front face 13 of which is radial and joins the rear end of the region 8 and of the grooves 9.
Le noyau 2 comporte par ailleurs un relief localisé 14 en saillie au fond d'une rainure 9. Ce relief s'étend axialement à partir de la face 13 et a, en vue en planThe core 2 also includes a localized relief 14 projecting from the bottom of a groove 9. This relief extends axially from the face 13 and has, in plan view
(Figure 5) , une forme à étranglement intermédiaire. Le noyau est par ailleurs pourvu d'un trou borgne axial 15 qui s'étend de. son extrémité avant à un emplacement intermédiaire de la partie 7, et, en arrière de ce trou 15, d'un trou borgne radial 16 prévu entre deux rainures 9 (Figures S et 6) .(Figure 5), a form with an intermediate constriction. The core is moreover provided with an axial blind hole 15 which extends from. its front end at an intermediate location of the part 7, and, behind this hole 15, a radial blind hole 16 provided between two grooves 9 (Figures S and 6).
Le manchon 3 (Figures 5 à 7) a une conformation intérieure conjuguée de la conformation- extérieure des parties 5 et 7 du noyau : une partie avant 17 convergente vers l'arrière suivant l'angle α, et une partie arrière 18 comportant une région avant 19A divergente vers l'arrière puis une région arrière cylindrique 19B, et sur laquelle font saillie six cannelures axiales 20 à surface interne cylindrique. Les parties 17 et 18 sont séparées par une nervure circulaire 21 dont le flanc avant est radial tandis que son flanc arrière est convergent vers l'avant (Figure 7) .The sleeve 3 (Figures 5 to 7) has an internal conformation combined with the external conformation of the parts 5 and 7 of the core: a front part 17 converging towards the rear at the angle α, and a rear part 18 comprising a region before 19A diverging towards the rear then a cylindrical rear region 19B, and on which six axial grooves 20 with cylindrical internal surface project. Parts 17 and 18 are separated by a circular rib 21 whose front flank is radial while its rear flank converges towards the front (Figure 7).
A l'extrémité arrière d'une cannelure 20 est prévue une empreinte 22 conjuguée du relief 14 du noyau, ouverte vers l'arrière.At the rear end of a groove 20 is provided an imprint 22 combined with the relief 14 of the core, open towards the rear.
Extérieurement, le manchon a une section qui est circulaire en regard de la partie 17 et grossièrement polygonale (carrée dans cet exemple) en regard de la partie 18. Le profil en long (Figure 5) est, d'avant en arrière, convexe, puis concave, puis sensiblement parallèle à l'axe X-X. Sur chaque face de la partie 18 sont formés des reliefs sans arête vive 23 (Figure 1) pour améliorer la prise de l'outil. Un orifice radial étage 24 est par ailleurs ménagé à travers le manchon, entre deux cannelures 20, et il est prévu à l'extrémité arrière de la surface cylindrique 19B un épaulement radial 25 en creux.Externally, the sleeve has a section which is circular opposite part 17 and roughly polygonal (square in this example) opposite part 18. The longitudinal profile (FIG. 5) is, from front to rear, convex, then concave, then substantially parallel to the axis XX. On each face of the part 18 are formed reliefs without sharp edge 23 (Figure 1) to improve the grip of the tool. A radial orifice stage 24 is also formed through the sleeve, between two grooves 20, and there is provided at the rear end of the cylindrical surface 19B a radial shoulder 25 hollow.
Le noyau 2 et le manchon 3 étant réalisés séparément par moulage par injection, le manchon est enfilé par l'avant sur le noyau (flèche F de la Figure 5), avec l'empreinte 22 dans le demi-plan radial du relief 14. Les cannelures 20 pénètrent dans les rainures 9, jusqu'à ce que les épaulements 10 du noyau butent sur les épaulements conjugués 25 du manchon. A la fin de ce mouvement, le relief 14 s'encliquette dans l'empreinte 22, et la nervure 21 s' encliquette dans la gorge 11. L'extrémité avant du manchon se trouve alors sensiblement au droit de la tranche d'extrémité 6- du noyau, laissant celle-ci apparente. Le manchon est alors solidarisé du noyau en rotation par les cannelures 20 et les rainures 9, et verrouillé en translation vers l'arrière par les épaulements 10 et vers l'avant par trois moyens : d'une part, la coopération -de la nervure 21 et de la gorge 11, d'autre part les surfaces en contre-dépouille 5 et 17, enfin l' encliquetage du relief 14 dans l'empreinte 22.The core 2 and the sleeve 3 being produced separately by injection molding, the sleeve is threaded from the front onto the core (arrow F in FIG. 5), with the imprint 22 in the radial half-plane of the relief 14. The grooves 20 penetrate into the grooves 9, until the shoulders 10 of the core abut on the conjugate shoulders 25 of the sleeve. At the end of this movement, the relief 14 engages in the cavity 22, and the rib 21 engages in the groove 11. The front end of the sleeve is then located substantially in line with the end edge 6 - of the nucleus, leaving it visible. The sleeve is then secured to the rotating core by the grooves 20 and the grooves 9, and locked in translation backwards by the shoulders 10 and forwards by three means: on the one hand, the cooperation -of the rib 21 and of the groove 11, on the other hand the surfaces in undercut 5 and 17, finally the snap of the relief 14 in the imprint 22.
Pour compléter et renforcer ce verrouillage, le pion 4 est enfoncé à force à travers l'orifice 24 et dans le trou 16 du noyau (Figure 6) .To complete and reinforce this locking, the pin 4 is force-fitted through the orifice 24 and into the hole 16 of the core (Figure 6).
L'ensemble des opérations de montage, y compris l'insertion à force de la partie arrière de la lame 1 dans le trou axial 15 du noyau, peut être réalisé de façon automatique. Il en est de même du marquage du manchon, qui est facile à saisir et à manipuler du fait de sa semi- rigidité.All the assembly operations, including the forced insertion of the rear part of the blade 1 into the axial hole 15 of the core, can be carried out automatically. The same applies to the marking of the sleeve, which is easy to grasp and handle due to its semi-rigidity.
Par « semi-rigidité », on entend la propriété d'être sensiblement indéformable mais tout de même suffisamment élastique pour se déformer légèrement sous l'action de forces élevées comme celles développées par une presse. Ceci s'oppose à la fois à la rigidité quasi-totale de la matière du noyau, et à la souplesse des élastomères.By “semi-rigidity” is meant the property of being substantially non-deformable but still sufficiently elastic to deform slightly under the action of high forces such as those developed by a press. This opposes both the almost total rigidity of the core material, and the flexibility of the elastomers.
A titre d'exemple, on peut réaliser le noyau en polypropylène ou en acétate de cellulose et le manchon en « polypropylène soft », qui est une matière vendue sous la dénomination commerciale « Santoprène » .For example, the core can be made of polypropylene or cellulose acetate and the sleeve of "soft polypropylene", which is a material sold under the trade name "Santoprene".
Suivant les applications, on peut avoir recours à toute combinaison appropriée des quatre moyens de verrouillage axial décrit ci-dessus (5-17, 11-21, 14-22 et 4-16-23) . Les trois premiers moyens de verrouillage sont entièrement - cachés par le manchon, tandis que le pion 4 est visible dans l'orifice 24 de celui-ci et peut alors servir de code couleur.Depending on the application, any suitable combination of the four axial locking means described above can be used (5-17, 11-21, 14-22 and 4-16-23). The first three locking means are entirely - hidden by the sleeve, while the pin 4 is visible in the orifice 24 thereof and can then be used as a color code.
En variante, le manchon peut être une pièce composite munie extérieurement, en totalité ou en partie, d'une couche superficielle plus ' souple (« grip ») , comme indiqué en 26 sur les Figures 5 et 7.As a variant, the sleeve can be a composite part provided externally, in whole or in part, with a more ' flexible ' surface layer (“grip”), as indicated at 26 in FIGS. 5 and 7.
En variante également, le noyau 2 peut être surmoulé sur la lame 1. Also in a variant, the core 2 can be molded onto the blade 1.
