The body portion 2 consists of three ladder-like portions 2r, 2n, and 2″′ each having one plate-like piece fixed between two supports,
The ladder-like parts 2t, 2rt, and 2'' are connected by hinges 5 attached to the ends of each of the two pillars, and are made of a rectangular plate with one end rotatably fixed to the side surface of the pillar,
A fixed hardware 6 having a locking hole at the other end and the fixed hardware 6
into the locking holes of the ladder-like portions 2', 2'' and 2''.
A locking pin 13' for holding and fixing each other at an angle of Oo is provided on the side surface of the support column.

A plurality of plate-like pieces are fixedly installed between two pillars at both ends of the body part 2, and have a length equal to the length of the body part 2 in the longitudinal direction divided by the length of the body part 2, and have a non-slip piece at the tip. The foot parts 1, 1 provided with insulating rubber feet 7°7 are connected to the pillars of the body part 2 by hinges 5' provided at the ends of the pillars of the foot parts 1, 1, and are made of a rectangular plate and have one end. The foot portion 1゜1 is rotatably fixed to the side of the support, and has a locking hole at the other end.
' and into the locking hole of the fixing hardware 6', and the leg portion 1
. Locking pins 1', 1' for holding and fixing along the leg portions 1, 1 are provided on the side surfaces of the support columns 1, 1.

Furthermore, traction wheels 3 are attached to the two pillars of the body portion 2. Carrying handle hardware 4. A backpack strap 10 is attached, and a transportation bundle 8 and a plurality of holes 9 for fixing objects are attached to the plate-like piece.
At the same time, a backpack strap storage box 11 is provided at the lower part of the plate-like piece of the central portion 2'' of the three ladder-like portions 2', 2'' and 2'' forming the torso portion 2.

How the stepladder of the present invention constructed in this way can be converted into a device that satisfies multiple purposes will be explained using the example shown in the drawings.

FIG. 1 is a folded side view of the multipurpose stepladder of the present invention.

This is the state when the stepladder is not in use or when the main stepladder is being transported or stored.

The entire structure is made from lightweight yet strong materials.

Figure 2 is a front view of the edge trapezoid step, and the foot part 1 in Figure 1 is
It can be easily reassembled by opening ゜1 to the left and right and locking it using the fixed hardware 6', 6'.

The multipurpose stepladder of the present invention can also be used as a stand for public telephones in the event of an emergency.

A rubber bottom of the telephone is inserted into the mounting object fixing hole 9 in FIG. 4 to improve stability.

Figure 3 is a front view of the stepladder, and the fixed hardware 6', 6 in Figure 2 is
The three ladder-like parts 2', 2'', and 2'' that make up the body part 2 are folded into three and erected by removing the left and right opening stops and joining them together.

This is the situation when the stepladder of the present invention is used for its original purpose.

FIG. 4 is a front view of the ladder when it is used as a ladder, and shows the leg portions 1, 1 of FIG. 1 in an open state (rotated by 180°).

Figure 5 shows a side view of the state in which it has been reassembled into a lightweight transport vehicle.
' is locked with the locking pin 13', cargo, etc. are loaded and transported using the transport bundle 8.

Figures 6 and 7 show how the backpack is reassembled when used as a backpack, and are a front view and a side view of the backpack.

FIG. 8 is a diagram showing the backpack storage box 11 and the storage state of the backpack.The backpack strap 10 is always stored in the storage box 11.
If necessary, it can be taken out and attached to the backpack strap 4 shown in Figure 6 to be used as a backpack.

In this way, the multipurpose stepladder of the present invention can be used for many different purposes by being reassembled for purposes other than its original purpose as a stepladder, and it has many advantages in terms of improved work efficiency and safety. be.
