    • The side extension of the invention includes first and second extension wall portions each circumscribing one-half of the area defined by the upstanding walls of the wagon body. The side extensions have a groove which is engaged by a lip extending from and disposed substantially perpendicular to the upstanding walls. The first and second extension wall portions have coupling elements formed at each end thereof which are secured to one another by bolts to lock the side extension on the wagon. The side extension when mounted on the wagon extends beyond the upstanding walls of the wagon body to increase the depth of the passenger department.
    • 本发明的侧面延伸部包括第一和第二延伸壁部,每个延伸壁部分围绕由货车车身的直立壁限定的区域的一半。 侧面延伸部具有凹槽,该凹槽由直立的壁延伸并基本上垂直于直立壁设置的唇缘接合。 第一和第二延伸壁部分具有形成在其每个端部处的联接元件,它们通过螺栓彼此固定以将侧向延伸部锁定在货车上。 在车上安装的侧面延伸超出了货车车身的直立墙壁,以增加客运部门的深度。

    • A fastener particularly adapted for securing an end of a cord in an opening in an object comprises a cylindrical shaped body. Extending through the fastener body is a passageway to hold an end of the cord, for example. In practice, the fastener preferably is made of plastic allowing the fastener to be molded onto the cord. Projecting outwardly on an angle from an inner end of the fastener body is an ear. Because the cord, the fastener ear, or both are flexible, the fastener ear and cord may be pressed into alignment. Once aligned, the fastener and cord end may be threaded through the opening in the object with the ear then returning to its prior nonaligned position. The cord is prohibited from being drawn back through the opening by an interference fit between the fastener ear and the object.
    • 特别适用于将绳索的端部固定在物体的开口中的紧固件包括圆柱形的主体。 通过紧固件本体延伸的是例如保持帘线端部的通道。 实际上,紧固件优选地由塑料制成,使得紧固件能够模制到绳索上。 从紧固件主体的内端以一定角度向外突出是耳朵。 由于绳索,紧固件耳朵或两者都是柔性的,所以紧固件耳朵和绳索可被压入对准。 一旦对准,紧固件和绳索端部可以通过耳朵穿过物体中的开口,然后返回到其先前的非对准位置。 通过紧固件耳朵和物体之间的过盈配合禁止绳索通过开口被拉回。
