    摘要： The present invention provides a roadway barrier or guard rail system which has a post (12) which passes through the carriage (20) with the carriage (20) being free to move up along the post (12). The carriage (20) is prevented from moving down the post (12) by means of a stop or restraint (12.60,12.50,12.40,12.30) which is separate from and underneath the carriage (20) and which the carriage (20) abuts, with the stop or restraint (12.60,12.50,12.40,12.30) being located on the post (12). The carriage (20) is not otherwise restrained from moving up the post except by the curved channels through the carriage (20) which engage the extremities of the post, and the friction this may produce. Further systems are provided with the same features but additionally additional frictional or other forces such as shearing forces, produced by means of formations or fixtures to the post or the carriage which must be overcome after the carriage starts moving relative to the post, such as restraints or stops on the post above the carriage. In other embodiments additional frictional or shear forces must be overcome before movement between the carriage (20) and the post (12) will occur. The movement of the carriage (2) on the post (12) is guided by formations on the carriage (20) cooperating with the mating formations on the post (12).

    摘要翻译： 本发明提供了一种道路障碍物或护轨系统，其具有通过托架（20）的柱（12），托架（20）可自由地沿柱（12）向上移动。 通过与托架（20）分开并位于托架（20）下方的止挡或约束（12.60,12.50,12.40,12.30），并且托架（20）邻接的托架（20）可防止托架（20）向下移动 停止或限制（12.60,12.50,12.40,12.30）位于该职位（12）。 滑架（20）不受其他限制，除了通过与柱的末端接合的托架（20）的弯曲通道以及可能产生的摩擦之外，可以向上移动柱。 进一步的系统具有相同的特征，但另外附加的摩擦力或其它力，例如剪切力，通过地层或固定装置产生到桩或滑架，在托架开始相对于桩柱移动之后必须克服，例如约束 或停在运输车上方。 在其他实施例中，在托架（20）和柱（12）之间的移动之前，必须克服额外的摩擦力或剪切力。 托架（2）在柱（12）上的移动由托架（20）上的与托架（12）上的配合结构配合的结构引导。
