Pulley 23 is formed to reciprocate along, one end is rotatably connected to the pulley 23, the other end is rotatable to the hinge hole 223 of the adjacent first or second link guides 22a, 22b The connection points of the ladder members are composed of a plurality of links 24 which are rotatably connected by hinges, the upper end of which is mounted on the case 1 and the lower end of which is mounted on the upper surface of the bottom plate 12. 2) and; The reducer 32 for reducing the rotational force generated by the handle 31 inside the case 1, the guide roll 33 to rotate in conjunction with the reducer 32, and one side of the guide roll 34 ) And the other end showed an evacuation ladder, characterized in that it consists of a winch (3) consisting of a traction wire (34) fixed to one side of the upper surface of the bottom plate (12).

In the present invention, most of the existing evacuation ladder was made in the shape of a ladder that is spread in a slide type, but in an emergency situation, there is a sense of stability that can be used for fear.

However, in the present case, a ladder pipe 21 serving as a ladder is formed, and both sides thereof have advantages in that the first and second link guides 22a and 22b are arranged like railings and used more stably.

In addition, the structure of the ladder member 3 presented herein has the advantage that can be folded relatively easily and stably when stored after use.

At this time, in the case of the winch (3) it is preferable to determine the rotation ratio of the handle 31 and the rotation of the guide roll 33 and to select a separate gear connection structure so that a large force acts with a small force, for this purpose Rotation by (31) is transmitted to the small gear and the small gear is engaged with the relatively large gear in conjunction with the guide roll 33 to overcome the load with a small force when folding the ladder member (2) It is desirable to be able to fold it. Although not shown, the bottom of the bottom plate 12 of the present invention may further include a landing stabilization means such as trivet.

5 is a perspective view showing the structure of a ladder member according to another embodiment of the present invention, the first link guide 22a is a ladder pipe mounting portion 221 is formed at one end, the guide hole 222 at the other end A hinge hole 223 is formed therebetween so as to be foldable on one side of the ladder member 2 by a plurality of links 24; The second link guide 22b has a ladder pipe mounting portion 221 formed at one end thereof, a hinge hole 223 formed at the other end thereof, and guide holes 222 formed therebetween, so that a plurality of links 24 may be formed. It is characterized in that the folding member is formed on the other side of the ladder member (2).

In the above embodiment, when the guide hole 222 is identically located at the front or the rear, even if the pulley 23 mounted on the guide hole 222 is made of a bearing that minimizes friction force, This is one place.
