    • The present disclosure relates to a telescoping step system which has at least one stringer assembly having telescopically coupled first and second tubular components. The second tubular component is telescopically extendable relative to the first tubular component. The stringer assembly is operably associated with a structure. The system further has at least one step assembly associated with one of the first and second tubular components. The stringer assembly is telescopically collapsible into a retracted position to form a compact assembly either adjacent to or within a portion of the structure, and extendable into an extended position extending outwardly from the structure. In the extended position the stringer assembly presents the step assembly as a platform which a user is able to step on to, and thus aids the user with ingress into and egress from the structure.
    • 本公开涉及一种伸缩台阶系统,其具有至少一个具有可伸缩耦合的第一和第二管状部件的纵梁组件。 第二管状部件相对于第一管状部件可伸缩地延伸。 纵梁组件可操作地与结构相关联。 该系统还具有与第一和第二管状部件之一相关联的至少一个步骤组件。 纵梁组件可伸缩地缩回到缩回位置,以形成与结构的一部分相邻或在该结构的一部分内的紧凑组件,并且可延伸到从结构向外延伸的延伸位置。 在延伸位置,纵梁组件将步骤组件呈现为用户能够踏上的平台,并且因此帮助用户进入和离开结构。
