摘要： An extendable/retractable ladder assembly includes a first stile and a second stile and a plurality of rungs extending therebetween. Each stile may comprise a plurality of columns disposed in a nested arrangement for relative axial movement in a telescopic fashion. A connector assembly connects the rungs to respective columns in the first and second stiles. The ladder has improved manufacturability since connector assemblies may be assembled before connecting the rungs to respective columns. The standing surface of the rungs may be angled such that it is rotated towards horizontal when the ladder assembly is leaned against a wall. A latch assembly may be used to selectively lock relative axial movement between adjacent columns. The latch assembly includes a locking pin assembly comprised of a central post and an outer metal sleeve. An air damper may also be used to control airflow through the columns.
摘要翻译：可伸缩梯子组件包括第一平台和第二平台以及在它们之间延伸的多个梯级。每个立柱可以包括以嵌套布置设置的多个列，以便以可伸缩的方式进行相对轴向运动。连接器组件将梯级连接到第一和第二平台中的相应列。梯子已经改善了可制造性，因为连接器组件可以在将梯级连接到相应的列之前进行组装。梯级的站立表面可以是倾斜的，使得当梯子组件靠在墙壁上时，其朝着水平方向旋转。闩锁组件可用于选择性地锁定相邻列之间的相对轴向运动。闩锁组件包括由中心柱和外部金属套筒组成的锁定销组件。还可以使用空气阻尼器来控制通过柱的气流。
