板７，８は折畳み展開可能となる。19 is a spring acting on the bearing pieces 1a and lb; 20 is a band fixing fitting attached to the footboard 8; 21 and 22 are ■-shaped pieces 9.
A chain plate support pipe connected to the chain plate 10 is inserted into a receiving frame 23, 24 fixed to the back surface of each tread plate 7, 8, and each tread plate 7, 8 can be folded and unfolded using this as a fulcrum.
２５は安定脚を示す。この考案は以上の構成であるから
、第１図及び第２図に示すように口形杆４を伸長させる
ことにより台車として用いることができ、その際荷物は
台板１のみでなく踏板８及び補助板１１にも載せられる
ので、搬送機能は倍増し、又第３図に示すように口形杆

ピン１３に引かけ、車輪３の軸受片１ａ、ｌｂを上方に
持上げることにより脚立として用いることもでき、しか
も折曲げ操作は極めて容易て迅速かつ確実に行うことが
できる。25 indicates a stabilizing leg. Since this device has the above structure, it can be used as a trolley by extending the mouth-shaped rod 4 as shown in FIGS. Since it can also be placed on the board 11, the conveyance function is doubled, and when the mouth-shaped rod 4 is bent as shown in FIG. It can also be used as a stepladder by lifting the bearing pieces 1a, lb of the wheel 3 upward, and the bending operation can be performed extremely easily, quickly and reliably.
従ってビデオ装置等重量物を運びかつ脚立を必要とする
テレビ関係者等の使用に好適である。Therefore, it is suitable for use by television personnel who carry heavy objects such as video equipment and require a stepladder.
