Les figures 1A, 1B, 1C représentent respectivement par une vue de dessus, une vue de dessous et une vue de profil arrière un exemple de réalisation d'un stylo 1 selon l'invention. Le stylo 1 a l'aspect d'un tube ayant ses deux extrémités biseautées selon un angle déterminé, ici de l'ordre de 12° relativement à son axe longitudinal. En observant la tranche biseautée du stylo 1, il apparaít que celui-ci comprend un tube externe 10, qui forme la paroi extérieure ou enveloppe du stylo, et une pièce tubulaire interne 20 coaxiale au tube 10, qui forme la paroi intérieure du tube. La pièce interne 20 semble elle-même constituée par deux couches tubulaires distinctes 21, 22, la couche 22 entourant la couche 21 et présentant une épaisseur plus forte que la couche 21. Ces couches correspondent à des pièces 21, 22-1 et 22-2 mentionnées plus loin en relation avec la description d'un exemple de réalisation de la pièce interne 20.Figures 1A, 1B, 1C respectively represent by a view from above, a view from below and a view from rear profile an example of a pen 1 according to the invention. Pen 1 has the appearance of a tube having its two ends bevelled at a determined angle, here of the order of 12 ° relative to its axis longitudinal. Observing the bevelled edge of the pen 1, it appears that the latter comprises an external tube 10, which forms the outer wall or envelope of the pen, and an internal tubular part 20 coaxial with the tube 10, which forms the inner wall of the tube.

The thinned end of the tube 10 has a longitudinal slot 12 allowing the flow of ink to the tip of the pen 11 and showing two feather tips 13, 14. The back end of the pen is bevelled the same way that the front end for reasons aesthetics and symmetry of the whole but could also, in an alternative embodiment, present a cross section profile.

Un tel stylo plume est d'un aspect surprenant en ce qu'il paraít entièrement creux vu de l'extérieur et semble dépourvu de tout système d'alimentation en encre. Selon l'invention, le corps du stylo comprend en réalité un réservoir d'encre dissimulé entre sa paroi intérieure et sa paroi extérieure, comme cela sera mieux compris en se référant aux figures 2A, 2B, et 3A, 3B.Such a fountain pen is of a surprising aspect in that that it appears entirely hollow when viewed from the outside and seems to lack any ink supply system. According to the invention, the body of the pen actually comprises an ink tank hidden between its inner wall and its outer wall, as will be better understood in referring to Figures 2A, 2B, and 3A, 3B.

Les figures 2A, 2B représentent le tube externe 10 avant son assemblage sur la pièce tubulaire interne 20, respectivement par une vue de dessus et une vue de dessous. Le tube 10 est par exemple en acier inoxydable et est emmanché en force sur la pièce tubulaire 20.Figures 2A, 2B show the outer tube 10 before it is assembled on the internal tubular part 20, respectively by a top view and a view from below. The tube 10 is for example made of stainless steel and is force fitted onto the tubular part 20.

Sur les figures 3A, 3B, il apparaít que la pièce tubulaire interne 20 comprend un tube central 21 de même longueur que le tube externe 10 et deux portions de tube 22-1, 22-2 emmanchées sur les deux extrémités du tube central 21. Les portions de tube 22-1, 22-2 présentent un diamètre extérieur sensiblement égal au diamètre intérieur du tube externe 10 et forment des entretoises d'assemblage du tube externe 10 sur le tube central 21. Le tube central 21 est par exemple en acier inoxydable et les entretoises 22-1, 22-2 sont par exemple en un métal ou un alliage d'une dureté moindre que l'acier, par exemple du laiton.In Figures 3A, 3B, it appears that the part internal tubular 20 includes a central tube 21 likewise length as outer tube 10 and two tube portions 22-1, 22-2 fitted on both ends of the tube central 21. The tube portions 22-1, 22-2 have a outer diameter substantially equal to the diameter inside of the outer tube 10 and form spacers assembly of the outer tube 10 on the central tube 21. The central tube 21 is for example made of stainless steel and the spacers 22-1, 22-2 are for example made of a metal or an alloy of less hardness than steel, for example of brass.

Les entretoises 22-1, 22-2 s'étendent chacune sensiblement sur un tiers de la longueur du tube central 21 et font apparaítre une région de longueur L où la face extérieure de la pièce tubulaire interne 20 présente un plus faible diamètre, ici le diamètre extérieur du tube 21. Ainsi, lorsque le tube externe 10 est emmanché sur la pièce tubulaire interne 20, cette région de plus faible diamètre forme un réservoir d'encre 24 qui est délimité dans le sens radial par la face extérieure du tube central 21 et la face intérieure du tube externe 10 (Fig. 2A), et est délimité dans le sens longitudinal par les bords des entretoises 22-1, 22-2 qui se trouvent en regard.Spacers 22-1, 22-2 each extend substantially over a third of the length of the central tube 21 and show a region of length L where the face outside of the internal tubular part 20 has a smaller diameter, here the outside diameter of the tube 21. Thus, when the outer tube 10 is fitted onto the internal tubular part 20, this region of weaker diameter forms an ink tank 24 which is delimited in the radial direction by the outside face of the tube central 21 and the inner face of the outer tube 10 (Fig. 2A), and is delimited in the longitudinal direction by the edges of spacers 22-1, 22-2 which are in look.

La pièce tubulaire interne 20 comprend d'autre part un système de distribution d'encre réalisé ici par gravure de canaux et de sillons à la surface de l'entretoise 22-2. Sur la figure 3A, on aperçoit ainsi sur le dessus de l'entretoise 22-2 :

  • deux canaux latéraux longitudinaux 230, 231 débouchant dans le réservoir 24,
  • un canal central longitudinal 232 agencé entre les deux canaux latéraux 230, 231,
  • une pluralité de sillons transversaux 233 reliant le canal central 232 aux canaux latéraux 230, 231, ici trente-deux sillons gravés de chaque côté du canal 232, et
  • un sillon central 234 prenant sa source dans le canal central 232, assurant l'écoulement de l'encre jusqu'à la plume 11 et se terminant à l'extrémité de l'entretoise 22-2, sous la fente 13 séparant les deux becs 13, 14 de la plume 11 (ce qui apparaít en superposant les figures 2A et 3A).
The internal tubular part 20 also comprises an ink distribution system produced here by etching channels and grooves on the surface of the spacer 22-2. In FIG. 3A, we can see on the top of the spacer 22-2:
  • two longitudinal side channels 230, 231 opening into the reservoir 24,
  • a longitudinal central channel 232 arranged between the two lateral channels 230, 231,
  • a plurality of transverse grooves 233 connecting the central channel 232 to the lateral channels 230, 231, here thirty-two grooves etched on each side of the channel 232, and
  • a central groove 234 originating in the central channel 232, ensuring the flow of the ink up to the pen 11 and ending at the end of the spacer 22-2, under the slot 13 separating the two spouts 13, 14 of the pen 11 (which appears by superimposing Figures 2A and 3A).

La pièce tubulaire interne 20 comprend également un canal 220 formant évent, pour maintenir le réservoir 24 à la pression atmosphérique et permettre l'écoulement de l'encre en direction de la plume. Le canal 220 est ici gravé à la surface de l'entretoise 22-1 et débouche à l'extrémité arrière du stylo. Comme on le verra plus loin, cet agencement du canal 220 permet d'assurer le remplissage du réservoir 24 au moyen d'un dispositif à dépression qui se fixe sur l'extrémité arrière du stylo.The internal tubular part 20 also includes a channel 220 forming a vent, to maintain the reservoir 24 at atmospheric pressure and allow the flow of ink in the direction of the pen. Channel 220 is here engraved on the surface of the spacer 22-1 and leads to the back end of the pen. As we will see more far, this arrangement of channel 220 makes it possible to ensure the filling of the reservoir 24 by means of a device depression which is fixed on the back end of the pen.

Dans un mode de réalisation qui n'est cité ici qu'à titre d'exemple, le tube externe 10 présente un diamètre intérieur de l'ordre de 9,45 mm et un diamètre extérieur de l'ordre de 10 mm. Les entretoises présentent un diamètre intérieur de l'ordre de 8,00 mm et un diamètre extérieur de l'ordre de 9,45 mm. Le tube central 21 présente un diamètre intérieur de l'ordre de 7,6 mm et un diamètre extérieur de l'ordre de 8 mm. La longueur des tubes 10, 21 est de l'ordre de 185 mm, et celle des entretoises 22-1, 22-2 de l'ordre de 65 mm. Le réservoir 24 s'étend ainsi sur une longueur de 55 mm et présente un volume de l'ordre de 0,9 cm3. Les canaux 230, 231, 232 sont pratiqués sur une longueur de l'ordre de 37,5 mm et une profondeur de l'ordre de 0,3 mm, l'angle de gravure des canaux 230, 231 étant de l'ordre de 44° et l'angle de gravure du canal 232 de l'ordre de 26°. La largeur du sillon 232 est de l'ordre de 0,1 mm et sa profondeur de l'ordre de 0,3 mm. La largeur des sillons 233 est de l'ordre de 0,1 mm et leur profondeur est de l'ordre de 0,6 mm. La largeur du sillon 220 est de l'ordre de 0,025 mm et sa profondeur de l'ordre de 0,4 mm.In an embodiment which is cited here only by way of example, the external tube 10 has an internal diameter of the order of 9.45 mm and an external diameter of the order of 10 mm. The spacers have an inside diameter of around 8.00 mm and an outside diameter of around 9.45 mm. The central tube 21 has an inside diameter of around 7.6 mm and an outside diameter of around 8 mm. The length of the tubes 10, 21 is of the order of 185 mm, and that of the spacers 22-1, 22-2 of the order of 65 mm. The reservoir 24 thus extends over a length of 55 mm and has a volume of the order of 0.9 cm 3 . The channels 230, 231, 232 are formed over a length of the order of 37.5 mm and a depth of the order of 0.3 mm, the etching angle of the channels 230, 231 being of the order of 44 ° and the engraving angle of channel 232 of the order of 26 °. The width of the groove 232 is of the order of 0.1 mm and its depth of the order of 0.3 mm. The width of the grooves 233 is of the order of 0.1 mm and their depth is of the order of 0.6 mm. The width of the groove 220 is of the order of 0.025 mm and its depth of the order of 0.4 mm.

La plume 11, représentée schématiquement sur les figures 1A à 3B, est susceptible en pratique de divers modes de réalisation. A titre d'exemple, la figure 4 illustre un mode de réalisation dans lequel la plume 11 présente une zone de rétrécissement obtenue par usinage des bords latéraux des becs 13, 14, l'extrémité de la plume 11 présentant une largeur sensiblement constante. L'extrémité de l'entretoise 22-2, qui sert de support au sillon 234, n'est pas usinée comme la plume 11 et conserve la forme conférée par le biseautage.The pen 11, represented schematically on the Figures 1A to 3B, is susceptible in practice to various embodiments. For example, Figure 4 illustrates an embodiment in which the pen 11 has a shrinkage area obtained by machining lateral edges of the spouts 13, 14, the end of the pen 11 having a substantially constant width. The end of the spacer 22-2, which serves to support the groove 234, is not machined like the nib 11 and retains the shape conferred by beveling.

La présente invention est bien entendu susceptible de diverses autres variantes et modes de réalisation, notamment en ce qui concerne les dimensions et la structure des pièces décrites ci-dessus et les matériaux utilisés pour les réaliser. Notamment, la paroi intérieure ou extérieure du corps d'un stylo selon l'invention n'a pas nécessairement un profil cylindrique et peut présenter un profil ovale ou sensiblement carré selon l'effet esthétique recherché. D'autre part, dans un mode de réalisation avantageux visant à réduire le prix de revient du stylo selon l'invention, la pièce interne 20 est réalisée en un seul bloc par injection d'une matière plastique dans un moule.The present invention is of course susceptible various other variants and embodiments, especially with regard to the dimensions and the structure of the parts described above and the materials used to make them. In particular, the wall inside or outside of the body of a pen depending the invention does not necessarily have a cylindrical profile and may have an oval or substantially square profile depending on the desired aesthetic effect. On the other hand, in a advantageous embodiment aimed at reducing the price cost of the pen according to the invention, the internal part 20 is produced in a single block by injection of a plastic in a mold.

De façon générale, il apparaítra clairement à l'homme de l'art que le stylo plume selon l'invention présente deux caractéristiques principales pouvant être mises en oeuvre chacune indépendamment de l'autre. Une caractéristique consiste dans le fait de prévoir une plume formée par un prolongement du matériau formant l'enveloppe du corps du stylo, ici le tube externe 10. L'autre caractéristique consiste dans le fait de prévoir un corps de stylo tubulaire ayant un réservoir d'encre logé entre sa paroi extérieure et sa paroi intérieure. Ainsi, une plume classique pourrait être fixée sur un corps de stylo selon l'invention, et un corps de stylo classique pourrait être revêtu d'une enveloppe métallique se prolongeant sous la forme d'une plume. La combinaison de ces deux caractéristiques constitue toutefois le mode de réalisation préféré de l'invention car elle permet de prévoir un corps de stylo ouvert à ses deux extrémités, la plume n'obstruant pas l'extrémité avant du stylo et formant un prolongement harmonieux du corps du stylo.In general, it will appear clearly at those skilled in the art that the fountain pen according to the invention has two main characteristics which can be implemented each independently of the other. A characteristic consists in providing a feather formed by an extension of the material forming the envelope of the pen body, here the outer tube 10. The other feature is to plan a tubular pen body having an ink reservoir housed between its outer wall and its inner wall. So a classic feather could be attached to a pen body according to the invention, and a pen body classic could be coated with a metal casing extending in the form of a feather. The combination of these two characteristics constitutes however the mode preferred embodiment of the invention because it allows provide a pen body open at both ends, the nib does not block the front end of the pen and forming a harmonious extension of the pen body.

Il entre toutefois dans le cadre de la présente invention de prévoir un stylo dont le corps a la structure décrite plus haut, tout en ayant une extrémité obstruée par un objet, une pièce quelconque ou par une paroi.However, it is within the scope of this invention of providing a pen whose body has the structure described above, while having one end obstructed by an object, any part or by a wall.

En raison de la structure particulière du stylo selon l'invention, il entre également dans le concept inventif général de la présente invention de prévoir un dispositif permettant de recharger le réservoir d'encre de ce stylo. Un tel dispositif 30 de remplissage du réservoir d'encre est représenté en coupe sur les figures 5A et 5B. Sur ces figures, le stylo 1 est représenté respectivement avant et après remplissage de son réservoir, et a son extrémité arrière engagée dans le dispositif 30 et son extrémité avant trempée dans un encrier. L'ensemble formé par le stylo 1 et le dispositif de remplissage 30 constitue un dispositif pour écrire.Due to the special structure of the pen according to the invention, it also falls within the concept general inventive of the present invention to provide a device for refilling the ink tank of this pen. Such a device 30 for filling the ink tank is shown in section in the figures 5A and 5B. In these figures, the pen 1 is shown respectively before and after filling his tank, and at its rear end engaged in the device 30 and its front end dipped in a inkwell. The assembly formed by the pen 1 and the device filling 30 constitutes a device for writing.

Le dispositif de remplissage 30 comprend un bloc 31 dans lequel est pratiquée une cavité 32 de réception de l'extrémité arrière du stylo 1. La cavité 32 comprend une excroissance cylindrique 34 venant s'emmancher dans la partie creuse de l'extrémité arrière du stylo. La cavité 32 est rendue étanche grâce à trois joints annulaires 33 agencés sur paroi intérieure de la cavité 32, à l'embouchure de la cavité 32, qui coopèrent avec la paroi extérieure du stylo, et grâce à trois joints annulaires 35 agencés autour de l'excroissance cylindrique 34, qui coopèrent avec la paroi intérieure du stylo. The filling device 30 comprises a block 31 in which is formed a cavity 32 for receiving the rear end of the pen 1. The cavity 32 comprises a cylindrical protrusion 34 fitting into the hollow part of the rear end of the pen. The cavity 32 is sealed by three annular seals 33 arranged on the inner wall of the cavity 32, at the mouth of the cavity 32, which cooperate with the wall outside of the pen, and thanks to three annular seals 35 arranged around the cylindrical projection 34, which cooperate with the inner wall of the pen.

La cavité de réception 32 est mise en dépression au moyen d'un système de pompage classique, intégré ici dans le bloc 31, comprenant un piston 36 monté coulissant dans une cavité cylindrique 37 grâce à un système à vis et à molette 38. La cavité 37 communique avec la cavité de réception 32 par l'intermédiaire d'un orifice d'aspiration 39. Lorsque le piston 36 est tiré vers l'arrière par une rotation de la molette 38, la dépression dans la cavité 32 se communique au réservoir d'encre 24 par l'intermédiaire du canal 220 formant évent, décrit plus haut, qui débouche dans la cavité 32. A l'autre extrémité du stylo, de l'encre est ainsi aspirée dans le réservoir 24 par l'intermédiaire de la plume, du sillon et des canaux reliant la plume au réservoir 24.The receiving cavity 32 is placed under vacuum at by means of a conventional pumping system, integrated here in the block 31, comprising a piston 36 slidably mounted in a cylindrical cavity 37 thanks to a screw system and wheel 38. The cavity 37 communicates with the cavity of reception 32 via an orifice suction 39. When the piston 36 is pulled towards the rear by a rotation of the wheel 38, the depression in cavity 32 communicates with the reservoir ink 24 through channel 220 forming vent, described above, which opens into cavity 32. At the other end of the pen, ink is thus sucked into tank 24 via the feather, furrow and canals connecting the feather to tank 24.

Il relève également du concept inventif général de la présente invention de prévoir un capuchon pour un tel stylo plume. Ici, l'idée de la présente invention est de prévoir un capuchon solidaire d'un étui prévu pour recevoir le corps du stylo. En effet, l'extrémité arrière du corps du stylo a la forme d'un tube creux dans le mode de réalisation préféré de la présente invention. Elle pourrait ainsi recevoir par mégarde de petits objets qui pourraient se bloquer à l'intérieur du corps. Elle pourrait également recevoir des saletés, par exemple si le stylo tombait sur un sol terreux ou poussiéreux ou tombait dans du sable. Il est donc avantageux, mais nullement impératif, d'associer aux moyens de protection de la plume des moyens de protection de l'ensemble du stylo. Ainsi, l'utilisateur est naturellement amené à protéger l'ensemble du stylo lorsqu'il ne s'en sert pas.It also falls under the general inventive concept of the present invention to provide a cap for such feather pen. Here, the idea of the present invention is to provide a cap integral with a case provided for receive the pen body. Indeed, the rear end of the pen body has the shape of a hollow tube in the mode preferred embodiment of the present invention. She could thus inadvertently receive small objects which could get stuck inside the body. She could also receive dirt, for example if the pen fell on earthy or dusty ground or fell into sand. So it's advantageous, but in no way imperative, to associate with the means of protection of the pen means of protection of the whole pen. Thus, the user is naturally led to protect the entire pen when it is not in use.

Les figures 6A et 6B représentent un exemple de réalisation d'un étui/capuchon selon l'invention, comprenant un étui 40 de forme étroite et longitudinale adaptée à la forme du stylo, pour le rangement et le transport du stylo, et une pièce 41 de réception de la plume 11, solidaire de l'étui 40, formant capuchon. La pièce de réception 41 comprend un évidement pour recevoir l'extrémité de la plume 11, et est montée rotative à l'une des extrémités de l'étui 40. La pièce de réception 41 a par exemple la forme d'une boule montée autour d'un axe (non représenté) passant par son centre, et est maintenue en position de réception de la plume grâce à une bille 42 coopérant avec une encoche à bords arrondis, la bille étant poussée dans l'encoche par un ressort 43. Sur les figures 6A, 6B, la bille 42 et le ressort 43 sont agencés dans un évidement pratiqué dans l'étui 40 et l'encoche est agencée à la surface de la pièce de réception 41. La bille 42 et le ressort peuvent également être agencés dans un logement pratiqué dans la pièce de réception 41, la bille 42 coopérant alors avec une encoche pratiquée à la surface de l'étui 40.Figures 6A and 6B show an example of production of a case / cap according to the invention, comprising a case 40 of narrow and longitudinal shape adapted to the shape of the pen, for storage and transport of the pen, and a piece 41 for receiving the feather 11, integral with the case 40, forming a cap. The receiving part 41 includes a recess for receiving the end of the pen 11, and is rotatably mounted at one end of the case 40. The reception room 41 for example has the shape of a ball mounted around a axis (not shown) passing through its center, and is maintained in the pen reception position thanks to a ball 42 cooperating with a notch with rounded edges, the ball being pushed into the notch by a spring 43. In FIGS. 6A, 6B, the ball 42 and the spring 43 are arranged in a recess in the case 40 and the notch is arranged on the surface of the workpiece reception 41. Ball 42 and spring can also be arranged in a housing in the room reception 41, the ball 42 then cooperating with a notch on the surface of the case 40.

Ainsi, la plume 11 est tout d'abord engagée dans la pièce de réception 41 en maintenant le stylo sensiblement droit. Le stylo est ensuite basculé dans l'étui 40 par un mouvement de rotation de la pièce 41 autour de son axe. Un couvercle 44 est ensuite rabattu sur l'étui.Thus, the pen 11 is first of all engaged in the receiving part 41 while holding the pen substantially law. The pen is then tilted into the case 40 by a rotational movement of the part 41 around its axis. A cover 44 is then folded over the case.
