Abstract

Herraje multirama (2), que comprende al menos tres ramas, obtenido por moldeado de un material compuesto, y más exactamente de una matriz termoplástica o termoendurecible reforzada con fibras, destinado al ensamblado de piezas que forman un ángulo entre ellas, que comprende al menos tres ramas o alas (4, 31, 32) planas o sustancialmente planas que se extienden radialmente desde una zona de unión (20), y del cual al menos una superficie o parte de superficie (30, 41, 42) es formada de modo que constituya una superficie de apoyo para una o varias de dichas piezas a fijar, presentando dicha zona de unión (20), por un lado, una sección, en la dirección transversal, es decir, perpendicular a la al menos una de dichas ramas o alas (4, 31, 32), en forma de un polígono de lados cóncavos, y la conexión de cada una de dichas ramas o alas (4, 31, 32) con otra rama o ala (4, 31, 32) vecina es realizada, por otro lado, mediante una porción en forma de lámina curva (21, 22, 34) que confiere a dicho zona de unión (20) una de sus formas cóncavas.
