DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refuge evacuation tool used when descending from a high place using a rope.

[0002]

2. Description of the Related Art Heretofore, evacuation from a high place or evacuation or some work has been performed by hanging a rope ladder or rope with bumps at predetermined intervals.

[0003]
