Description

Dispositif traceur pour stylographe à pointe tubulaire Tracer device for stylograph with tubular tip
L'invention concerne un dispositif traceur pour stylographe à pointe tubulaire du type comportant un réseau d'alimentation de l'encre, à partir d'un réservoir vers la pointe et un réseau de régulation du débit de l'encre. Le réseau de régulation a pour but d'établir une liaison entre l'intérieur du dispositif traceur et le milieu extérieur. Lors du traçage, il permet de remplacer par de l'air les quantités d'encre utilisées et de compenser les phénomènes de pression et de dépression à l'intérieur du dispositif provoqués par les variations de température agissant sur le dispositif.The invention relates to a tracer device for a stylus with a tubular tip of the type comprising an ink supply network, from a reservoir towards the tip, and an ink flow regulation network. The purpose of the regulation network is to establish a connection between the interior of the tracer device and the external environment. During the tracing, it makes it possible to replace by air the quantities of ink used and to compensate for the phenomena of pressure and depression inside the device caused by the variations of temperature acting on the device.
L'intérêt étant de construire des stylographes possédant un réservoir de fort volume, le réseau de régulation doit posséder une capacité de régulation la plus importante possible. Généralement, ce réseau se présente sous la forme d'une rampe constituée par un filetage hélicoïdal placé dans l'alésage intérieur ou à l'extérieur d'une pièce du dispositif.The interest being to build stylographs having a large volume reservoir, the regulation network must have the greatest possible regulation capacity. Generally, this network is in the form of a ramp formed by a helical thread placed in the inner bore or outside of a part of the device.
Le principe de remplissage d'un tel réseau est basé sur le principe de capillarité et de compensation des pressions internes et externes.The principle of filling such a network is based on the principle of capillarity and compensation of internal and external pressures.
Afin d'augmenter le volume du réseau de régulation, il a été proposé de construire des dispositifs traceurs munis d'un réseau de régulation constitué par une double rampe hélicoïdale. Ainsi, le brevet FR-2502067 du 28 décembre 1981 décrit un stylographe à pointe scriptrice comprenant un corps extérieur constituant l'enveloppe du stylo, un corps intermédiaire muni d'un filetage extérieur formant une première rampe de régulation et un corps intérieur muni d'un filetage extérieur constituant une deuxième rampe de régulation. La rampe externe de régulation comπunique avec la rampe interne de régulation et avec le réseau d'alimentation principal en encre et le réseau de compensation ainsi constitué communique avec le milieu extérieur.In order to increase the volume of the regulation network, it has been proposed to build tracer devices provided with a regulation network constituted by a double helical ramp. Thus, patent FR-2502067 of December 28, 1981 describes a stylographer with a writing tip comprising an external body constituting the envelope of the pen, an intermediate body provided with an external thread forming a first regulation ramp and an internal body provided with an external thread constituting a second regulation ramp. The external control ramp with the internal control ramp and with the main ink supply network and the compensation network thus formed communicates with the outside environment.
Les dispositifs traceurs de l'état de la technique sont par ailleurs munis d'une masselotte interne pouvant être assistée d'un ressort à boudins permettant d'absorber les accélérations verticales auxquelles ils sont soumis. Cette masselotte possède un poids relativement important et occupe un certain volume à l'intérieur du dispositif, en particulier dans les stylographes à main pour lesquels le principe d'action de la masselotte est la gravité.The tracer devices of the state of the art are moreover provided with an internal counterweight which can be assisted by a coil spring making it possible to absorb the vertical accelerations to which they are subjected. This weight has a relatively large weight and occupies a certain volume inside the device, in particular in hand-held stylographs for which the principle of action of the weight is gravity.
Les dispositifs traceurs selon 1'état de la technique présententThe tracer devices according to the state of the art have
DE REMPLACEMENT l'inconvénient de posséder généralement une mauvaise étanchéité de la chambre de régulation. Par ailleurs, tous les dispositifs existants, présentent une chambre de régulation dont le volume est relativement réduit par la taille de la masselotte et par les limites imposées par l'ergonomie du diamètre extérieur du dispositif et des normes de fabrication de ces dispositifs.OF SUBSTITUTION the disadvantage of generally having a poor seal of the regulation chamber. Furthermore, all the existing devices have a regulation chamber whose volume is relatively reduced by the size of the counterweight and by the limits imposed by the ergonomics of the external diameter of the device and the manufacturing standards of these devices.
La présente invention a pour but de présenter un dispositif traceur pour stylographe à pointe tubulaire ne présentant pas les inconvénients de l'état de la technique. Ainsi, le dispositif traceur selon l'invention comprend un corps extérieur muni d'un filetage définissant une rampe externe de régulation et constituant l'enveloppe extérieure dudit dispositif, un corps intermédiaire muni d'un filetage définissant une rampe interne de régulation, d'un corps intérieur et d'une plume traceuse reliée à une masselotte. Afin d'assurer l'étanchéité parfaite de la rampe interne de régulation, le corps intérieur est constitué par un fourreau en matériau élastomère possédant une chambre interne constituant le réseau d'alimentation principal en encre et dans lequel est disposée une masselotte. Selon une variante préférentielle, le fourreau intérieur est prolongé en son extrémité la plus proche de la plume traceuse par une continuité formant ressort. La masselotte est une masselotte tubulaire munie d'une portée. Cette caractéristique permet à la masselotte de ne plus travailler uniquement en gravité puisque les accélérations sont absorbées par le ressort du fourreau élastomère. Ceci permet de réduire sensiblement la taille de la masselotte qui se présente sous la forme d'un tube d'un diamètre selon la section transversale très faible.The object of the present invention is to present a tracer device for a stylograph with a tubular tip which does not have the drawbacks of the state of the art. Thus, the tracer device according to the invention comprises an external body provided with a thread defining an external regulation ramp and constituting the external envelope of said device, an intermediate body provided with a thread defining an internal regulation ramp, an inner body and a tracer feather connected to a flyweight. In order to ensure perfect sealing of the internal regulation ramp, the internal body is constituted by a sheath made of elastomeric material having an internal chamber constituting the main ink supply network and in which a counterweight is arranged. According to a preferred variant, the inner sheath is extended at its end closest to the tracer pen by a continuity forming a spring. The counterweight is a tubular counterweight provided with a bearing surface. This characteristic allows the counterweight to no longer work solely in gravity since the accelerations are absorbed by the spring of the elastomer sheath. This makes it possible to significantly reduce the size of the counterweight which is in the form of a tube with a diameter along the very small cross section.
Selon une variante avantageuse, le corps intermédiaire du dispositif est pourvu d'ergots ; le ressort du fourreau élastomère plaque la portée de la masselotte tubulaire contre ces ergots. Cette disposition permet d'optimiser la fonction ressort. Selon une variante, le ressort possède une section transversale carrée ou rectangulaire. Selon une autre variante, le ressort possède une section transversale grossièrement semi-circulaire. Le ressort peut également être ajouré sur son pourtour. Préférentiellement, le matériau constituant le fourreau élastomère est choisi parmi les matériaux les plus souples utilisés dans l'état de la technique. La présente invention ainsi que les avantages qu'elle présente seront mieux compris à l'aide d'un mode de réalisation du dispositif traceur conforme à l'invention représenté schématiquenient, à titre d'exemple nonAccording to an advantageous variant, the intermediate body of the device is provided with lugs; the spring of the elastomer sheath presses the bearing surface of the tubular counterweight against these pins. This arrangement optimizes the spring function. Alternatively, the spring has a square or rectangular cross section. According to another variant, the spring has a roughly semi-circular cross section. The spring can also be perforated around its periphery. Preferably, the material constituting the elastomer sheath is chosen from the most flexible materials used in the state of the art. The present invention and the advantages it presents will be better understood using an embodiment of the tracer device according to the invention shown diagrammatically, by way of example not
