摘要： A collapsible ladder (1) having hollow ladder bars (2, 3) and ladder steps (4). Two ladder bars are interconnected at one end by one ladder step to form U-shaped ladder sections, which are telescopically inserted into each other. The upper ends of the ladder bars comprise each a retaining mechanism (6). A locking pin (8) projects into a locking hole in the ladder bar of the adjacent upper ladder section. The retaining mechanisms are actuated outside the space between the ladder steps (4), preferably on the front side of the ladder, and are designed to be released manually and individually. The locking pins (8) project in their locking positions into the hollow space (9) in the locked ladder section in order to provide safety units, designed to prevent the bar portions from passing the locking pin of a bar section.

摘要翻译： 一种具有空心梯杆（2,3）和梯子台阶（4）的可折叠梯子（1）。 两梯杆在一端通过一个阶梯互连，以形成可伸缩地相互插入的U形阶梯部分。 梯杆的上端包括每个保持机构（6）。 一个锁定销（8）伸入相邻的上阶梯部分的梯杆上的锁定孔中。 保持机构在梯子阶梯（4）之间的空间外侧，优选地在梯子的前侧上被致动，并且被设计为手动地且单独地释放。 锁定销（8）在其锁定位置中伸入锁定梯子部分的中空空间（9）中，以提供安全单元，该安全单元设计成防止杆部分通过杆部分的锁定销。
