Claims (1)
上位梯子と、両梯子にわたつて設ける操作ロープ
とからなり、操作ロープを操作することによつて
上位梯子を下位梯子に沿つて伸縮昇降させるよう
にした伸縮梯子において、操作ロープ解放時に上
位梯子または下位梯子が独自に伸張移動するのを
阻止するためロツク機構を設けてなる伸縮梯子。 It consists of a lower ladder, an upper ladder that engages with the lower ladder so as to be able to move up and down, and an operating rope that spans both ladders, and by operating the operating rope, the upper ladder is extended and retracted up and down along the lower ladder. A telescoping ladder as described above, which is provided with a locking mechanism to prevent the upper ladder or the lower ladder from independently extending and moving when the operating rope is released.
