Abstract

The invention relates to a writing instrument of the type comprising a body (1) and a cap, which elements can be assembled by screwing, in which the writing element (3, 13) is mounted so as to slide inside the body. According to the invention, the thread onto which the cap can be screwed is formed on a piece integral with the writing element. In the writing position, this threaded portion is retracted into the said body and, in the rest position, in other words when the cap is placed on the writing element, the cap bears against the body of the writing element under the stress of an elastic-return member (25).

Description

La présente invention concerne un instrument à écrire et, de façon précise, des moyens propres à assurer le maintien d'un capuchon sur le corps de celui-ci.The present invention relates to a writing instrument and, specifically, means suitable for ensuring the maintenance of a cap on the body thereof.

La technique antérieure a proposé de nombreux systèmes permettant, de façon plus ou moins efficace, de réaliser un tel maintien. L'un des moyens les plus connus, et l'un des plus simples également, consiste à prévoir sur le corps et le capuchon des filetages permettant de solidariser ces deux éléments par visage.The prior art has proposed numerous systems making it possible, more or less effectively, to carry out such maintenance. One of the best known means, and one of the simplest also, is to provide threads on the body and the cap making it possible to secure these two elements by face.

Ce mode d'assemblage présente cependant deux types d'inconvénients, l'un d'ordre pratique, l'autre d'ordre esthétique.This method of assembly, however, has two types of drawbacks, one practical, the other aesthetic.

En effet, on sait que le blocage du capuchon n'est véritablement réalisé qu'à la fin de l'opération de vissage. Il en résulte, à l'inverse, qu'un léger dévissage est suffisant pour assurer la désolidarisation du capuchon et du corps.Indeed, it is known that the locking of the cap is not really achieved until the end of the screwing operation. It results, conversely, that a slight unscrewing is sufficient to ensure the separation of the cap and the body.

On pourrait, bien entendu, envisager un système de freinage s'opposant à la libération accidentelle du corps et du capuchon en jouant sur les tolérances d'usinage des filetages de ces deux éléments. Cependant, il est clair que, dans le cas d'une production industrielle, il serait extrêmement difficile et coûteux d'obtenir ainsi des frotte­ments réguliers.One could, of course, consider a braking system opposing the accidental release of the body and the cap by playing on the machining tolerances of the threads of these two elements. However, it is clear that, in the case of industrial production, it would be extremely difficult and costly to obtain regular friction in this way.

C'est pourquoi, dans la pratique, ce type de dispositif de fixation ne présente pas les qualités de sécurité requises et on lui préfère généralement, pour cette raison, des systèmes à encliquetage.This is why, in practice, this type of fastening device does not have the required safety qualities and it is generally preferred, for this reason, snap-fastening systems.

D'autre part, ce mode d'assemblage par vissage nécessi­te, sur le corps de l'instrument à écrire, au voisinage de la pointe d'écriture, la présence d'un filetage, destiné à coopérer avec un filetage correspondant, ménagé dans la partie interne du capuchon. Si ce dernier est dissimulé à la vue de l'utilisateur, il n'en est pas de même du premier, ce qui, sur le plan de l'esthétique, constitue un inconvénient sérieux.On the other hand, this method of assembly by screwing requires, on the body of the writing instrument, in the vicinity of the writing tip, the presence of a thread, intended to cooperate with a corresponding thread, provided in the inner part of the cap. If the latter is concealed in the eyes of the user, it is not the same for the first, which, in terms of aesthetics, constitutes a serious drawback.

La présente invention vise à proposer des moyens permet­tant de solidariser par visage un corps et un capuchon de stylo, qui ne présentent pas les inconvénients ci-dessus.The present invention aims to provide means for securing by face a body and a pen cap, which do not have the above drawbacks.

A cet effet, l'invention a pour objet un instrument à écrire du type comportant un corps et un capuchon assemblables par vissage, dans lequel l'élément scripteur est monté coulissant à l'intérieur du corps, caractérisé en ce que, de première part, le filetage sur lequel peut être vissé le capuchon est ménagé sur une pièce solidaire de l'élément scripteur, en ce que, d'autre part, en position d'écriture, cette partie filetée est escamotée dans ledit corps et, en ce que, de troisième part, en position de repos, c'est-à-dire, lorsque le capuchon est en place sur l'élément scripteur, le capuchon prend appui contre le corps de l'instrument à écrire sous la sollicitation d'un organe de rappel élastique.To this end, the subject of the invention is a writing instrument of the type comprising a body and a cap which can be assembled by screwing, in which the scripting element is slidably mounted inside the body, characterized in that, firstly , the thread on which the cap can be screwed is formed on a part integral with the scripting element, in that, on the other hand, in the writing position, this threaded part is retracted in said body and, in that , thirdly, in the rest position, that is to say, when the cap is in place on the writing element, the cap bears against the body of the writing instrument under the action of an organ elastic return.

Suivant la présente invention, le capuchon est donc appliqué contre le corps de l'instrument à écrire pendant une partie du vissage et pendant également toute la phase de dévissage, jusqu'à sa libération, instantanée, d'avec la corps.According to the present invention, the cap is therefore applied against the body of the writing instrument during part of the screwing and also during the entire unscrewing phase, until its instantaneous release from the body.

Il en résulte que les frottements ainsi créés s'opposent à tout dévissage accidentel du capuchon.As a result, the friction thus created opposes any accidental unscrewing of the cap.

Contrairement aux stylos de la technique antérieure, dont le capuchon est vissé sur le corps, il n'apparaît, au cours de la phase de dévissage, aucun interstice entre le capuchon et le corps, ce qui, sur le plan ornemental, présente un avantage certain.Unlike the pens of the prior art, the cap of which is screwed onto the body, there is no gap between the cap and the body during the unscrewing phase, which is advantageous from an ornamental point of view. certain.

Enfin, toujours sur le plan de l'esthétique, on constate que le filetage réalisé sur l'embout d'écriture s'escamote au cours de la libération du capuchon, de sorte qu'il est masqué au cours de la phase d'utilisation de l'instrument à écrire.Finally, still in terms of aesthetics, we see that the thread made on the writing tip retracts during the release of the cap, so that it is hidden during the use phase of the instrument to write.

D'autres avantages de la présente invention seront mis en évidence dans la description qui va suivre, d'une forme de mise en oeuvre de l'invention, donnée à titre d'exemple non limitatif. Dans cette description, on se réfèrera aux dessins annexés, sur lesquels :
Les figures 1 à 3 représentent, en coupe partielle, un instrument à écrire suivant l'invention, constitué d'un stylo à plume, respectivement en position d'écriture, au cours de la phase de mise en place du capuchon, et en position de repos ;
La figure 4 montre, sous forme développée, le profil de la rainure utilisée dans un type de mécanisme permettant de mettre en oeuvre l'invention.Other advantages of the present invention will be highlighted in the description which follows, of an embodiment of the invention, given by way of nonlimiting example. In this description, reference will be made to the appended drawings, in which:
Figures 1 to 3 show, in partial section, a writing instrument according to the invention, consisting of a fountain pen, respectively in the writing position, during the phase of fitting the cap, and in the position rest ;
FIG. 4 shows, in developed form, the profile of the groove used in a type of mechanism making it possible to implement the invention.

Sur les figures 1 à 4, l'instrument à écrire suivant l'invention est essentiellement constitué d'un corps 1, d'un embout d'écriture 3, d'un mécanisme 5 et d'un capuchon 7.In FIGS. 1 to 4, the writing instrument according to the invention essentially consists of a body 1, a writing tip 3, a mechanism 5 and a cap 7.

L'embout d'écriture 3 est équipé d'une plume 11 ainsi que de moyens d'alimentation en encre de celle-ci, non représentés en détail sur le dessin. Il est solidaire d'un tube 13 assurant, par un canal interne, l'alimentation de la plume, et dont la partie externe fait partie d'un méca­nisme 5 connu dans la technique pour permettre de faire sortir et rentrer une pointe d'écriture par une simple action sur un poussoir.The writing tip 3 is equipped with a pen 11 and with ink supply means thereof, not shown in detail in the drawing. It is integral with a tube 13 ensuring, by an internal channel, the feeding of the pen, and the external part of which is part of a mechanism 5 known in the art for allowing a writing tip to come out and come in. by a simple action on a pusher.

Un tel mécanisme comprend une bague 15 vissée dans le corps 1, à l'intérieur de laquelle coulisse le tube 13. Cette bague est munie d'une rainure circulaire 19. Le tube 13 est creusé sur sa paroi externe d'une rainure 23, dont le profil développé, connu en soi, a sensiblement la forme montrée à la figure 4. Les rainures 19 et 23 ont une profon­deur sensiblement égale au rayon d'une bille 21, qui est interposée entre lesdites rainures.Such a mechanism comprises a ring 15 screwed into the body 1, inside which the tube 13 slides. This ring is provided with a circular groove 19. The tube 13 is hollowed out on its outer wall with a groove 23, whose developed profile, known per se, has substantially the shape shown in Figure 4. The grooves 19 and 23 have a depth substantially equal to the radius of a ball 21, which is interposed between said grooves.

Un ressort de compression 25 prend appui, d'une part, sur la bague 15 et, d'autre part, sur une douille circulaire 27 formant butée solidaire du tube 13.Le ressort 25 tend ainsi à ramener vers l'intérieur du corps l'embout d'écriture 3.A compression spring 25 bears, on the one hand, on the ring 15 and, on the other hand, on a circular sleeve 27 forming a stop integral with the tube 13. The spring 25 thus tends to bring the writing end piece 3 towards the inside of the body.

Dans la position de la figure 1, qui est la position d'écriture, la bille 21,sous la sollicitation du ressort 25, se trouve au point A de la rainure 23 et le filetage de l'embout 3 est dissimulé à l'intérieur du corps 1.In the position of FIG. 1, which is the writing position, the ball 21, under the stress of the spring 25, is located at point A of the groove 23 and the thread of the end piece 3 is hidden inside body 1.

Lorsque l'utilisateur veut disposer le capuchon 7 sur son instrument à écrire, il lui suffira d'exercer une pression F sur le tube 13, par l'intermédiaire de moyens quelconques, non représentés sur le dessin. Sous cette action, la rainure 23 se déplacera par rapport à la bille 21, et celle-ci suivra le chemin ABC (figure 4). Lorsque l'utilisateur cessera d'exercer une pression sur le tube 13, le ressort de rappel 25 déplacera le tube 13, et donc la rainure 23, devant la bille 21, laquelle suivra alors le trajet CD. L'embout d'écriture sera alors dans la position de la figure 2.When the user wants to have the cap 7 on his writing instrument, it will suffice for him to exert pressure F on the tube 13, by any means, not shown in the drawing. Under this action, the groove 23 will move relative to the ball 21, and the latter will follow the path ABC (Figure 4). When the user ceases to exert pressure on the tube 13, the return spring 25 will move the tube 13, and therefore the groove 23, in front of the ball 21, which will then follow the path CD. The writing tip will then be in the position of FIG. 2.

Dès lors, l'utilisateur pourra commencer à visser le capuchon 7 du stylo sur l'embout d'écriture 3.From then on, the user can start screwing the cap 7 of the pen onto the writing tip 3.

Dès que le capuchon entera en contact avec le corps 1, tout vissage supplémentaire aura pour effet de déplacer le tube 13 et donc la rainure 23, à l'encontre de l'action du ressort 25, de façon à faire parcourir le trajet DE à la bille. Le stylo se trouve alors en position de repos, comme montré à la figure 3.As soon as the cap comes into contact with the body 1, any additional screwing will have the effect of displacing the tube 13 and therefore the groove 23, against the action of the spring 25, so as to make the path travel DE to the marble. The pen is then in the rest position, as shown in Figure 3.

Au cours de la phase de dévissage, la bille se déplace par rapport à la rainure suivant le trajet EA. Dès que les pas de vis du capuchon et du corps ne sont plus en prise, l'embout d'écriture 3 est rappelé à l'intérieur du corps par le ressort 25 est l'ensemble du mécanisme se trouve dans la position de la figure 1. On constate que, tout au long de cette phase de dévissage et jusqu'à la libération complète du capuchon 7, celui-ci est maintenu en contact, sous l'action du ressort 25, avec le corps 1.During the unscrewing phase, the ball moves relative to the groove along the path EA. As soon as the threads of the cap and of the body are no longer in engagement, the writing endpiece 3 is returned to the interior of the body by the spring 25 and the entire mechanism is in the position of the figure. 1. It can be seen that, throughout this unscrewing phase and until the cap 7 is completely released, the latter is kept in contact, under the action of the spring 25, with the body 1.

Dans ces conditions, il est clair qu'un dévissage accidentel du capuchon est insuffisant pour provoquer la libération du corps du stylo. Par ailleurs, le filetage de l'embout 3 étant dissimulé au regard, lorsque le stylo est en position d'utilisation (figure 1), le stylo présente un aspect harmonieux pour l'utilisateur.Under these conditions, it is clear that an unscrewing accidental cap is insufficient to cause release of the pen body. Furthermore, the thread of the nozzle 3 being hidden from view, when the pen is in the position of use (FIG. 1), the pen has a harmonious appearance for the user.

De la description qui précède, on constate que, si la présente invention fait appel à des mécanismes connus,ceux-ci ne sont pas utilisés dans les modes de fonctionnement habituels. En effet, dans les dispositifs de la technique antérieure (stylos à bille, par exemple), la position de la bille au point A correspond à la position d'utilisation, alors que, dans le cas présent, elle fait partie de la phase dans laquelle on met le dispositif en position de repos. Enfin, dans la technique antérieure, la position E est une position transitoire, que le mécanisme n'occupe que pendant un temps très bref, alors que, dans le dispositif de l'invention, il s'agit de la position de l'instrument à écrire.From the above description, it can be seen that, if the present invention calls upon known mechanisms, these are not used in the usual operating modes. Indeed, in the devices of the prior art (ball point pens, for example), the position of the ball at point A corresponds to the position of use, whereas, in the present case, it is part of the phase in which puts the device in the rest position. Finally, in the prior art, position E is a transient position, which the mechanism only occupies for a very short time, whereas, in the device of the invention, it is the position of the instrument to write.

Bien entendu, la présente invention peut faire appel, pour sa mise en oeuvre, à des mécanismes connus en soi autres que celui qui vient d'être décrit.Of course, the present invention may use, for its implementation, mechanisms known per se other than that which has just been described.
