    • PROBLEM TO BE SOLVED: To prevent being into a bulky form by contraction during non-use. SOLUTION: This extensive ladder 1 for a ship comprises a pair of extensive vertical members 2 formed uniformly at both sides and a plurality of steps 3 provided across both vertical members, the ladder having an upper end mounted on a hull portion. Each of the vertical members is formed in a multicylindrical shape in a contracted condition and in an extended condition with multicylindrical bodies 10a-10f relatively displaced in the axial direction to overlap each other at their ends, where outer face protruded portions 11 protruded on the outer faces of the cylindrical bodies located inside overlapping portions engage inner face protruded portions 12 protruded on the inner faces of the cylindrical bodies located outside the overlapping portions in sequence to maintain a predetermined extended condition. A constraining band 19 is provided in a releasable manner for keeping the vertical members in a contracted condition by constraining the plurality of steps in the contracted condition. In addition, a constraint releasing lever 20 is provided for applying force to the lower part of the ladder in the direction of extending the ladder. A supporting portion 21 is provided extending from both sides of at least one step to the hull side where a rubber roller 25 provided at the end abuts on the surface of the hull.
    • 要解决的问题:为了防止在不使用期间通过收缩而成为大体积的形式。 解决方案:这种广泛的梯子1包括一对在两侧均匀地形成的大量垂直构件2和跨越两个垂直构件设置的多个台阶3,梯子具有安装在船体部分上的上端。 每个垂直构件在收缩状态和延伸状态下形成为多个圆柱形状,其中多个圆柱体10a-10f在轴向方向上相对位移,在其端部彼此重叠,其中外表面突出部分11在外部突出 位于重叠部分内部的圆柱体的表面接合依次突出在位于重叠部分外侧的圆柱体的内表面上的内表面突出部分12,以保持预定的延伸状态。 限制带19以可释放的方式设置,以通过在收缩状态下约束多个台阶来将垂直构件保持在收缩状态。 此外,设置约束解除杆20,用于在梯子的延伸方向上向梯子的下部施加力。 设置有从至少一个台阶的两侧延伸到船体侧的支撑部分21,其中设置在该端部处的橡胶辊25邻接在船体的表面上。
