Claims

[Scope of utility model registration request]

(1) Make two horizontal rows of bendable vertical rods made by connecting ropes, chains, or multiple links in sequence, or non-bending vertical rods like pillars, and place branch rods inside each of the two vertical rods. In a ladder in which the left and right branch bars are connected at the end of the horizontal rung and the rung is shaped like a swing, a rotation prevention mechanism is provided on the vertical bar and the branch bar to prevent the horizontal rung from swinging on only one side of the ladder. A ladder that can be moved.

(2) Utility model registration claim consisting of a detent mechanism in which a protrusion is provided on either the vertical bar or the branch bar, and the protrusion hits the other bar to determine the rotation stop position of the branch bar. Ladder described in (1).

(3) A protrusion that protrudes laterally is provided on either the vertical bar or the branch bar, and this protrusion and the other bar are connected by a connecting body, and the branch bar stops rotating by this connecting body. A ladder according to claim (1) of the utility model registration, which comprises a detent mechanism for determining the position.
