Abstract

En una presilla elástica (9) para sujetar un riel de ferrocarril, que comprende en primer término una primera porción (1) sustancialmente recta, después una segunda porción, curvada, (2), seguidamente una tercera porción (3) sustancialmente recta cuyo eje forma un ángulo sustancialmente mayor de 45 grados con respecto al eje de la primera porción (1), estando los dos ejes en un mismo plano, a continuación una cuarta porción (4) que es una curva invertida, seguida por una quinta porción (5), y por una sexta porción (6) que es otra curva invertida, y finalmente una séptima porción (7), estando la primera porción (1) formada de manera de comprender una región (1B) que tiene una superficie de forma general cilíndrica que se extiende a lo largo de la totalidad de su longitud y una parte (1A, 1C) que se extiende longitudinalmente y que tiene una superficie que es menos convexa que la región (1B) que tiene una superficie de forma general cilíndrica, de la primera porción (1). Por lo menos parte de la segunda porción (2) y por lo menos parte de la tercera porción (3) son preferentemente manufacturados con superficies sustancialmente planas (2A, 3A) en las respectivas regiones laterales de las mismas y que se hallan en contacto con el riel cuando la presilla (9) se halla en uso.In an elastic clip (9) for holding a railroad rail, which comprises first a substantially straight first portion (1), then a second, curved portion (2), then a substantially straight third portion (3) whose axis it forms an angle substantially greater than 45 degrees with respect to the axis of the first portion (1), the two axes being in the same plane, then a fourth portion (4) which is an inverted curve, followed by a fifth portion (5 ), and by a sixth portion (6) which is another inverted curve, and finally a seventh portion (7), the first portion (1) being formed so as to comprise a region (1B) having a generally cylindrical surface which extends along its entire length and a part (1A, 1C) that extends longitudinally and that has a surface that is less convex than the region (1B) that has a generally cylindrical surface, of the first portion ( one). At least part of the second portion (2) and at least part of the third portion (3) are preferably manufactured with substantially flat surfaces (2A, 3A) in the respective lateral regions thereof and which are in contact with the rail when the clip (9) is in use.
