La figura 1 muestra una vista de una bobina que incorpora el mandil de la invención. Figure 1 shows a view of a coil incorporating the mandrel of the invention.
10 La figura 2 muestra una vista en perspectiva de una realización del mandil de la invención donde los nervios tienen configuración radial respecto al eje del cuerpo tubular. 10 Figure 2 shows a perspective view of an embodiment of the mandrel of the invention where the ribs have a radial configuration with respect to the axis of the tubular body.
La figura 3A muestra una vista en perspectiva de una realización del mandil de la invención donde los nervios tienen configuración ortogonal respecto a un plano medial. Figure 3A shows a perspective view of an embodiment of the mandrel of the invention where the ribs have an orthogonal configuration with respect to a medial plane.
15 La figura 3B muestra una sección por un plano transversal al eje del cuerpo tubular que pasa por una zona de ventanas, de la realización mostrada en a figura 3ª. Figure 3B shows a section through a plane transverse to the axis of the tubular body passing through a window area, of the embodiment shown in Figure 3.
20 El mandril para bobinas (1) de la invención es del tipo que comprenden un cuerpo tubular (2) cilíndrico alrededor del que se arrolla la bobina (1) donde, según la invención: -el cuerpo tubular (2) se encuentra materializado en plástico, y -el cuerpo tubular (2) comprende unas ventanas (3) aligeradoras en su contorno. The mandrel for coils (1) of the invention is of the type comprising a cylindrical tubular body (2) around which the coil (1) is wound where, according to the invention: -the tubular body (2) is materialized in plastic, and the tubular body (2) comprises lightening windows (3) in its contour.
25 Muy preferentemente (ver figs 2, 3A y 3B) las ventanas (3) se encuentran definidas por unos anillos (4) transversales y unos nervios (5, 50, 51) longitudinales que se encuentran relacionando dichos anillos (4), ya que los anillos (4) proporcionan apoyo al arrollamiento de la bobina (1) impidiendo deformaciones o colapsos gracias al arrostramiento entre los mismos que Very preferably (see figs 2, 3A and 3B) the windows (3) are defined by transverse rings (4) and longitudinal ribs (5, 50, 51) that are related to said rings (4), since the rings (4) provide support to the winding of the coil (1) preventing deformations or collapses thanks to the dragging between them
30 proporcionan los nervios (5). 30 provide the nerves (5).
En la realización mostrada en la figura 2 hay unos primeros nervios (5) que tienen configuración radial respecto al eje (20) del cuerpo tubular (2), lo que proporciona una resistencia uniforme en todo el cuerpo tubular (2). In the embodiment shown in Figure 2 there are first ribs (5) that have radial configuration with respect to the axis (20) of the tubular body (2), which provides a uniform resistance throughout the tubular body (2).

En la realización mostrada en las figuras 3 y 3B hay unos segundos nervios (50) que tienen configuración ortogonal, respecto a un plano medial (25), esto es, los segundos nervios (50) son paralelos entre sí a cada lado de dicho plano medial (25) que pasa por el eje (20) del cuerpo tubular, lo que facilita el desmoldeo de éste en dos mitades de molde, no representadas, que In the embodiment shown in Figures 3 and 3B there are some second ribs (50) that have orthogonal configuration, with respect to a medial plane (25), that is, the second ribs (50) are parallel to each other on each side of said plane medial (25) passing through the axis (20) of the tubular body, which facilitates the demoulding of the latter in two mold halves, not shown, which
5 salgan paralelamente en la dirección de los segundos nervios (50) por ambos lados, pudiendo disponer unos terceros nervios (52) coplanares con dicho plano (25), como se ve en la fig 3B. Lógicamente en cualquiera de las realizaciones el espesor de anillos (4) y nervios (5, 50, 51) será el suficiente para lograr la resistencia requerida, lo que se estudiará en cada caso. 5 exit parallel in the direction of the second ribs (50) on both sides, being able to disposing a third coplanar ribs (52) with said plane (25), as seen in fig 3B. Logically in any of the embodiments the thickness of rings (4) and nerves (5, 50, 51) will be enough to achieve the required resistance, which will be studied in each case.
10 Además, se ha previsto que el cuerpo tubular (2) comprenda dos zonas extremas ciegas (21), desprovistas de ventanas, ya que muchas veces la bobina (1) se maneja introduciendo los dedos por los extremos del cuerpo tubular (2), y los nervios podrían ocasionar lesiones o abrasiones al operario. 10 In addition, it is provided that the tubular body (2) comprises two blind end zones (21), devoid of windows, since many times the coil (1) is handled by inserting the fingers through the ends of the tubular body (2), and the nerves could cause injuries or abrasions to the operator.
15 Por último, indicar que el cuerpo tubular (2) se encuentra materializado en plástico de resistencia adecuada, por ejemplo, polietileno, poliestireno o polipropileno. 15 Finally, indicate that the tubular body (2) is made of plastic of suitable strength, for example, polyethylene, polystyrene or polypropylene.
Descrita suficientemente la naturaleza de la invención, así como la manera de realizarse en la práctica, debe hacerse constar que las disposiciones anteriormente indicadas y Sufficiently described the nature of the invention, as well as the manner in which it is carried out in practice, it should be noted that the provisions indicated above and
