(Means and Examples for Solving the Problems) This invention includes:
In the case of a folding ladder in which two bars 2.3 are assembled in an X shape and a large number of these are connected in succession to form a vertical bar of a pantograph structure, the way this ladder is used is that when it is suspended, the structure of the pantograph structure is The left and right vertical bars 1.1 are characterized by being elongated bar-shaped squares.

To explain in more detail, the rods 2 and 3 are
The two frames 2.3, which are arranged in an "X" shape, are connected to each other at both ends to form a continuous pantograph structure. 5 and 6 are connecting shafts of each rod 2 and 3. And the left and right vertical bars l, 1 axis 4 made of this pantograph structure
, 4 to step on the stick 7. ... to form a ladder structure, and the top of this ladder is connected to the mounting part 8 by a shaft 4a. The mounting portion 8 is provided in the manhole A. This ladder can be folded and stored within the frame of the mounting part 8.

Note that 9 is a latch and 9a is a handle. The IO is a rocking prevention protrusion that is provided on the shaft 4, and when the ladder is unfolded, it hits a locking part 11 provided on the attachment part 8 to stop the ladder from swinging back and forth.

(Function) Normally, the ladder is folded and stored inside manpole A as shown in Figure 2. When in use, when the handle 9a is turned, the ladder is released from the latch 9, and the ladder is unfolded and hung as shown in FIG. At that time, the ladder has both frames 2 set in an × shape,
3 are in contact at both ends of both frames at 5°6 to form a bundle, and the left and right vertical bars 1.1 form a single bar. By forming a single bar in this way, when the user goes up and down, the vertical bars l, l

(Effect of the invention) In general, when using a hanging ladder with a bent vertical bar, the ladder bends greatly due to the user's weight, and the user's legs are positioned above the user's body, causing the hanging body to become like a shrimp. It's curved and doesn't go up and down smoothly. The ladder of this invention has a simple structure as long as it has the above configuration, and since the vertical bar of the suspended ladder is in the form of a single bar, the ladder does not bend and can be smoothly ascending and descending in an emergency. be exposed.

Since the ladder is in the state where the pantographs assembled in an X are fully extended, the ladder structure is less than a predetermined length, so it is economical because it serves its purpose with a small amount of constituent material.
