Ladder and ladder crosspiece
A ladder and a ladder crosspiece are provided. In one embodiment, a ladder includes a first assembly having a first pair of spaced apart rails and a plurality of rungs extending between and coupled to the first pair of spaced apart rails. At least one crosspiece of the plurality of crosspieces may include a first support surface portion, a second support surface portion, and a channel extending between the first support surface portion and the second support surface portion. In one embodiment, the rear surface of each of the first pair of spaced apart tracks defines a plane, and the first support surface portion is located on a first side of the plane and the second support surface portion is located on a second side of the plane. In one embodiment, at least another crosspiece is positioned entirely on a first side of the plane.
提供了一种梯子和梯子横档。在一个实施例中，梯子包括第一组件，该第一组件具有第一对间隔开的轨道和多个横档，所述多个横档在所述第一对间隔开的轨道之间延伸并且联接到所述第一对间隔开的轨道。所述多个横档中的至少一个横档可以包括第一支撑表面部分、第二支撑表面部分以及通道，所述通道在所述第一支撑表面部分和所述第二支撑表面部分之间延伸。在一个实施例中，所述第一对间隔开的轨道中的每一个的后表面限定平面，并且所述第一支撑表面部分位于所述平面的第一侧上，而所述第二支撑表面部分位于所述平面的第二侧上。在一个实施例中，至少另一个横档完全定位在所述平面的第一侧上。
