Description
Bolígrafo que comprende unos medios para evitar la inclinación de la parte recta del muelle de compresión de bola.Ballpoint pen comprising means to avoid the inclination of the straight part of the compression spring of ball.
La presente invención se refiere al sector técnico de los bolígrafos. Como es sabido, por ejemplo en la patente US-A-6.220.774, dichos bolígrafos comprenden un depósito de tinta que comunica con un orificio típicamente cilíndrico asociado al canal capilar de una punta que presenta una cavidad en el interior de la cual está dispuesta la bola para escribir.The present invention relates to the sector pens technician. As is known, for example in the patent US-A-6,220,774, said pens they comprise an ink tank that communicates with a hole typically cylindrical associated with the capillary channel of a tip that it has a cavity inside which the ball to write
Dicha bola, cuando no se está utilizando el bolígrafo para escribir, se mantiene apretada contra un borde de retención, formado asimismo en dicha punta, con el fin de impedir la fuga de la tinta, y esta función es realizada por un muelle resistente a la compresión que aprieta sobre la bola mediante el extremo libre de una parte recta que constituye un extremo de dicho muelle. Cuando se utiliza el bolígrafo, al estar apretado contra la superficie sobre la que debe escribir, la bola mencionada anteriormente está apretada contra la parte interior de la punta y, al vencer la resistencia del muelle, está desplazada del borde de retención por una cantidad suficiente para permitir que la tinta que se utiliza para escribir pase hacia el exterior.Said ball, when the pen to write, stays pressed against an edge of retention, also formed on said tip, in order to prevent ink leakage, and this function is performed by a spring compression resistant that squeezes on the ball through the free end of a straight part that constitutes an end of said dock. When the pen is used, when pressed against the surface on which to write, the ball mentioned It is previously pressed against the inside of the tip and, when the spring resistance is overcome, it is displaced from the edge of retention for an amount sufficient to allow the ink to It is used to write pass outwards.
Dado que las dimensiones de las distintas partes componentes mencionadas anteriormente son, como es sabido, muy reducidas, la parte recta del muelle citada anteriormente presenta asimismo un diámetro muy reducido (del orden de unas cuantas décimas de un milímetro) y, cuando se aprieta en sentido axial durante la acción de escribir, con frecuencia desliza sobre la superficie de la bola, flexionándose con respecto a la parte restante del muelle, y, estando desplazada de la posición inicial que coincide con el eje longitudinal del bolígrafo, está dispuesta de modo que su extremo libre está dispuesto en un punto lateral de la bola en la proximidad de dicho borde de retención.Since the dimensions of the different parts components mentioned above are, as is known, very reduced, the straight part of the quay mentioned above presents also a very small diameter (of the order of a few tenths of one millimeter) and, when tightened axially during the writing action, often slides on the surface of the ball, flexing with respect to the remaining part of the pier, and, being displaced from the initial position that coincides with the axis length of the pen, is arranged so that its end free is arranged at a lateral point of the ball in the vicinity of said retaining edge.
En esta posición, la parte recta del muelle ejerce sobre la bola, durante la acción de escribir, una fuerza que comprende un componente transversal considerable que mantiene dicha bola apretada en sentido transversal contra el borde de retención y dado que existe necesariamente un juego entre dicho borde y la bola, la sección transversal anular a través de la que fluye la tinta no es simétrica con respecto al eje del bolígrafo, y presenta una longitud que, en lugar de ser constante, varía entre cero y un valor máximo que procede en sentido circunferencial alrededor de la bola, alcanzando a dicho valor máximo una talla que permite que la tinta salga en un flujo a un régimen mayor que el caudal previsto durante la etapa de diseño, calculándose dicho caudal según la viscosidad de la tinta y una anchura uniforme de la sección transversal anular de flujo.In this position, the straight part of the dock exerts on the ball, during the action of writing, a force that it comprises a considerable transverse component that maintains said ball pressed transversely against the retaining edge and since there is necessarily a game between said edge and the ball, the annular cross section through which the ink flows does not It is symmetrical with respect to the axis of the pen, and has a length that, instead of being constant, varies between zero and a value maximum that proceeds circumferentially around the ball, reaching that maximum value a size that allows the ink exits in a flow at a rate greater than the expected flow rate during the design stage, said flow rate being calculated according to the viscosity of the ink and a uniform width of the annular cross section of flow.
La situación anterior hace que, a lo largo de las líneas de escritura, aparezcan unas manchas dispuestas aleatoriamente, lo que crea un efecto poco estético que se asocia automáticamente con una baja calidad del bolígrafo.The above situation causes that, throughout the writing lines, appear some arranged spots randomly, which creates an unesthetic effect that is associated Automatically with low pen quality.
Además, en la zona de las manchas mencionadas anteriormente, la tinta, que forma unas zonas con un espesor mayor que normal, no puede secarse rápidamente y, si de forma no fortuita un usuario roza dichas manchas con la mano o el brazo, dichas manchas se extiendan produciendo unas marcas poco estéticas y asimismo el usuario ensucia su mano o brazo.In addition, in the area of the mentioned spots previously, the ink, which forms areas with a greater thickness that normal, can not dry quickly and, if not accidental a user rubs said spots with the hand or arm, said spots spread producing some aesthetic marks and also the user dirties his hand or arm.
El inventor del objeto de la presente solicitud ha intentado proporcionar una solución al problema descrito anteriormente, y ha desarrollado un bolígrafo del tipo descrito anteriormente, en el que dicho canal capilar, a través del cual atraviesa dicha parte recta del muelle de compresión de bola, está dotado de unos medios para impedir la inclinación de dicha parte con respecto al eje longitudinal del bolígrafo.The inventor of the object of the present application has tried to provide a solution to the problem described previously, and has developed a pen of the type described above, in which said capillary channel, through which crosses said straight part of the ball compression spring, is equipped with means to prevent the inclination of said part with with respect to the longitudinal axis of the pen.
En ciertas formas de realización de la invención, dichos medios consisten en unas partes ampliadas que forman una sección estrecha del canal capilar en cuyo interior dicha parte recta del muelle está introducida de manera aproximadamente complementaria con un juego mínimo.In certain embodiments of the invention, said means consist of enlarged parts that they form a narrow section of the capillary channel in whose interior said straight part of the spring is inserted approximately Complementary with a minimum game.
El objetivo de la presente invención consiste, por lo tanto, en proporcionar un bolígrafo tal como se describe en la reivindicación 1 adjunta. A continuación, se proporcionará una descripción más detallada de dos formas de realización preferidas del bolígrafo según la invención, haciendo referencia asimismo a los dibujos adjuntos en los que:The objective of the present invention is, therefore, in providing a pen as described in attached claim 1. Next, a more detailed description of two preferred embodiments of the pen according to the invention, also referring to the attached drawings in which:
- la Figura 1 representa una sección transversal longitudinal ampliada a través de algunas partes de un bolígrafo diseñado de acuerdo con el estado actual de la técnica, mientras que se está utilizando para escribir;- Figure 1 represents a cross section Longitudinal enlarged through some parts of a pen designed according to the current state of the art, while is being used to write;
- la Figura 2 representa una sección transversal longitudinal ampliada a través de algunas partes de una primera forma de realización de un bolígrafo según la invención;- Figure 2 represents a cross section longitudinal extension through some parts of a first embodiment of a pen according to the invention;
- la Figura 3 representa una sección transversal longitudinal ampliada a través de algunas partes de una segunda forma de realización de un bolígrafo según la invención.- Figure 3 represents a cross section longitudinal enlarged through some parts of a second embodiment of a pen according to the invention.
Haciendo referencia a la Figura 1, se puede observar cómo un bolígrafo 101 según el estado de la técnica comprende un depósito de tinta (del cual únicamente se ilustra de forma esquemática una pequeña parte) que comunica con un orificio cilíndrico 10 asociado a un canal capilar 3 de una punta 4 provista de una cavidad 9 que constituye un asiento para la bola 5 para escribir, y en cuyo interior acaba dicho canal capilar 3.Referring to Figure 1, you can observe how a pen 101 according to the state of the art it comprises an ink tank (of which only illustrated by schematic form a small part) that communicates with a hole cylindrical 10 associated with a capillary channel 3 of a tip 4 provided of a cavity 9 constituting a seat for the ball 5 for write, and inside which said capillary channel 3 ends.
Se mantiene la bola apretada contra un borde de retención 9t formado en el contorno hacia el exterior de dicha cavidad 9, debido al empuje ejercido por un muelle resistente a la compresión 6 que acaba en una parte recta 6r alineada con el eje longitudinal M-M del bolígrafo 101, cuyo extremo libre 6p (ilustrado en líneas continuas) está en contacto con la bola 5. Dicha parte recta 6r atraviesa en sentido coaxial un canal capilar cilíndrico 3 y, cuando se utiliza el bolígrafo 101 para escribir, tal como se indica en la figura, la fuerza Q que actúa sobre la bola 5 es transmitida a ella en un punto P y provoca la flexión de la misma con respecto al punto 0 donde la parte recta 6r está conectada a las partes restantes del muelle 6, haciendo que se incline (hacia la derecha en el dibujo) con respecto a dicho eje M-M.The ball is held tight against an edge of retention 9t formed in the outward contour of said cavity 9, due to the thrust exerted by a spring resistant to the compression 6 that ends in a straight part 6r aligned with the shaft longitudinal M-M of the pen 101, whose end 6p free (illustrated in solid lines) is in contact with the ball 5. Said straight part 6r coaxially crosses a channel cylindrical capillary 3 and, when pen 101 is used to write, as indicated in the figure, the force Q that acts on ball 5 it is transmitted to it at a point P and causes the flexion thereof with respect to point 0 where the straight part 6r is connected to the remaining parts of the dock 6, causing it to tilt (to the right in the drawing) with respect to said axis M-M
Como consecuencia, a partir de ese momento, la parte recta 6r ejerce sobre la bola 5 una fuerza reactiva no axial que comprende un componente significativo en sentido transversal que provoca los inconvenientes descritos anteriormente.As a consequence, from that moment, the straight part 6r exerts a non-axial reactive force on the ball 5 which comprises a significant transverse component that It causes the inconveniences described above.
En la Figura 2, en su lugar, se puede apreciar como, en una primera forma de realización 1 de un bolígrafo según la invención, el fenómeno descrito anteriormente se evita mediante la creación en el canal capilar 3 de una sección estrecha cilíndrica 7 que presenta un eje que coincide con el eje longitudinal N-N del bolígrafo, es atravesada por la parte recta 6r del muelle 6 y presenta unas dimensiones y una forma que prácticamente complementen las de dicho muelle (salvo un juego muy reducido, acentuado en el dibujo - que se deja para permitir cualquier expansión térmica del material de que está realizado el muelle 6, que se diferencia ligeramente de la expansión térmica del material de que está realizada la punta 4). Dado que en la situación ilustrada anteriormente, podría existir una obstrucción en el flujo de la tinta a través de dicha sección estrecha 7, que está escondida parcialmente por la parte recta 6r del muelle 6, el inventor ha previsto la posibilidad de formar una o más ranuras pasantes y radiales 8i que conectan dicha cavidad 9 constituyente del asiente para la bola 5 a dicho orificio con el que comunica el depósito de tinta 2.In Figure 2, instead, you can see as, in a first embodiment 1 of a pen according to the invention, the phenomenon described above is avoided by the creation in the capillary channel 3 of a narrow cylindrical section 7 which has an axis that coincides with the longitudinal axis N-N of the pen, is crossed by the straight part 6r of the dock 6 and presents dimensions and a shape that practically complement those of said dock (except for a game very reduced, accentuated in the drawing - which is left to allow any thermal expansion of the material from which the spring 6, which differs slightly from the thermal expansion of the material of which tip 4) is made. Since in the situation illustrated above, there might be a blockage in the flow of the ink through said narrow section 7, which is hidden partially by the straight part 6r of the spring 6, the inventor has provided for the possibility of forming one or more through grooves and radial 8i connecting said cavity 9 constituent of the seat for the ball 5 to said hole with which it communicates the tank of ink 2.
La Figura 3 representa como, en una segunda forma de realización 11 del bolígrafo según la invención, todas las distintas partes componentes citadas en la descripción de la primera forma de realización son idénticas (y por esta razón están designadas con los mismos números de referencia), salvo la sección estrecha 7' que, en este caso, no consiste en una limitación cilíndrica, pero está formada, en el canal capilar 3, mediante un anillo 12 que presenta una sección transversal semicircular que sobresale hacia el interior y cuyo eje coincide con el eje longitudinal N-N del bolígrafo 11.Figure 3 represents how, in a second embodiment 11 of the pen according to the invention, all different component parts cited in the description of the first embodiment are identical (and for this reason they are designated with the same reference numbers), except for the section narrow 7 'which, in this case, does not consist of a limitation cylindrical, but it is formed, in capillary channel 3, by a ring 12 having a semicircular cross section that protrudes inward and whose axis coincides with the axis N-N longitudinal of the pen 11.
En ambos de los casos ilustrados en las Figuras 2 y 3, dichas secciones estrechas 7, 7', con independencia de su forma, se mantienen sustancialmente fijas, es decir, orientadas a lo largo del eje longitudinal N-N del bolígrafo 1, 11, la parte recta 6r del muelle 6, cuyo extremo libre 6p siempre aprieta por lo tanto en sentido axial sobre la bola 5 en una posición sustancialmente central, evitando los inconvenientes mencionados anteriormente.In both of the cases illustrated in the Figures 2 and 3, said narrow sections 7, 7 ', regardless of their shape, they remain substantially fixed, that is, oriented towards length of the longitudinal axis N-N of the pen 1, 11, the straight part 6r of the spring 6, whose free end 6p always tighten therefore axially on ball 5 in a substantially central position, avoiding inconvenience mentioned above.
Mediante un bolígrafo según la invención, por lo tanto, se ha podido alcanzar el objetivo perseguido por el inventor, es decir, proporcionar un bolígrafo con líneas de escritura que son más uniformes y sin la formación de unas manchas y/o bordes borrones.By means of a pen according to the invention, therefore therefore, the objective pursued by the inventor has been achieved, that is, provide a pen with writing lines that are more uniform and without the formation of spots and / or edges blots
