梯子。 A pipe is attached to the upper part of the vertical bar of the ladder body, and a guide corner and a latching groove are formed in this pipe,
Insert the grip rod into the pipe with the convex portion of the grip rod aligned with the guide corner of the pipe, and
After pulling out the grip bar from the pipe, rotate it and fit the convex part of the grip rod into the locking groove of the pipe, thereby maintaining the grip bar in a state protruding above the vertical bar; Furthermore, a plurality of connecting members having both ends rotatably inserted into the vertical bar of the ladder main body are attached in the longitudinal direction of the ladder main body, and a plurality of supports each having a length approximately the same as the length of the ladder main body are attached to the connecting member. An evacuation ladder that can be slid freely through.
