て使用するようにしていた。 By the way, this type of stepladder usually has the upper ends of both ladder-shaped legs connected so that the legs can be opened using a stepladder hinge, and a top plate, sometimes referred to as a cloth board or treadle, is attached to this. When using this, when the work area is narrow, the legs of one stepladder are closed and carried, and when the work area is open, the legs are opened and used as a scaffold, and when the work area is wide, Several stepladders are individually carried by several people to the work area, and each stepladder's legs are opened and stood up at the work area, and the length of the scaffolding board to be placed and fixed on each stepladder is determined based on the scope of the work area and the length of the scaffolding board to be placed and fixed on each stepladder. The distance between each stepladder was adjusted accordingly, each stepladder was used as a scaffold body, and a long tread was stretched and fixed on the top plate, and this was used as a scaffold.

この持ち運びの不便さを除去したものとして、
両脚の下端に車輪を取付けて脚輪付きの脚立とな

Attach wheels to the lower ends of both legs to create a stepladder with wheels. When carrying, open both legs of each stepladder to make it stand up. The wheels make it easy to move. A version with fixed leg rings was also developed.

等があつた。(Problems to be solved by the invention) As mentioned above, the stepladder, which is the main body of the scaffold and is equipped with wheels for transportation, can be moved individually by opening its legs and standing in an upright position. Although it has become extremely easy to move around, when several stepladders with wheels are used and treads are strung between them to create a scaffold, these several stepladders are connected only by the treads. Therefore, depending on the distance, moving in this assembled state would be extremely unstable, and moving with work tools etc. on the treads would pose a risk of unexpected accidents. .

さらに、この種の脚立は、その高さが一定のも
のが多い関係上、作業性に乏しいという感があつ
た。 Furthermore, since most of these stepladders have a fixed height, I felt that they lacked workability.

ころに特徴を有するものである。(Means for Solving the Problems) In view of the above-mentioned circumstances, the present invention provides a scaffold that is extremely easy to disassemble and assemble, and when assembled as a scaffold at a work site, etc. When assembled as a scaffold, the mutual positional relationship of its component parts is forcibly restrained and becomes immovable, ensuring safety as a scaffold and ensuring that the transition of the work area is In order to move the scaffold with each wheel, two wheels were used to create a maneuverable scaffold that could be moved safely and quickly without changing the relative position of each component. The upper ends of each leg of approximately the same shape and size are hinged to form a ladder shape with a large number of horizontal bars for footrests placed at intervals between the pillars, allowing the legs to open and close freely, and a top plate that also serves as a step. Several stepladders are attached as scaffold bodies, and the several stepladders are placed in a row along the leg opening direction and at intervals, and placed across the top plate of each stepladder. The distance is longer than the distance from the front leg of the first stepladder to the rear leg of the last stepladder in the plurality of stepladders arranged and erected in a row, including a fixed footboard;
Separate straight pipes attached to each of the pillars on both sides in the same row are fixed to one of the pillars of each of the several stepladders, so that the mutual positional relationship of the several stepladders is immovable. The shaft is provided with a shaft that protrudes from the fixing ring body for fixing the fixing ring body and rotatably supports the fixing ring body on the pipe, and also for regulating the leg spacing of each of the several legs itself. A plurality of stepladder spacing regulating members that are used in common are each attached to the shaft, and are fixed to the other pillar of each of the plurality of stepladders, so that each of the plurality of stepladders can be attached together with the stepladder spacing regulating member. A fixing ring for adjusting the distance between the legs to a desired distance is also rotatably attached, and has a fixing device to the pipe, and a short sliding pipe is slidably fitted onto the pipe. The sliding short pipes of the several leg spacing regulating members provided are fitted onto the pipes, and the wheel support holding rods rotatably holding the wheel supports supporting the wheels for transportation are attached to the upper and lower sides. Each leg ring is constructed by fixing several leg rings each having a leg ring body that is fixedly supported at a location to the pipe at the upper end of the leg ring body at intervals. It is unique in that it is constructed with a stay pipe with wheels for connecting to another stepladder, making it a mobile scaffolding with wheels.

のとする。(Function) As mentioned above, the mobile scaffolding with wheels according to the present invention is composed of several stepladders as the scaffold bodies, a stay pipe with wheels for connecting each stepladder, and a tread, and this is used. To do this, open the ladder-shaped pillars of each stepladder and stand them up.
These are arranged in a line along the leg opening direction, taking into consideration the length of the treadle to be used and the height of the work area.
A ring for fixing the stepladder spacing regulating member that is attached to the pipe for forming the stay pipe with wheels for connecting the stepladder for each of the two pillars for forming one leg of each stepladder that are in the same row. By fixing each body, the distance between each stepladder is regulated and immovable, and among the two pillars for forming the other leg, each of the pillars in the same row is used for connecting the stepladder. While fixing the fixing rings of the leg spacing regulating member movably supported by the short sliding tubes fitted onto the pipes for forming the wheeled stay pipe,
By fixing each of the short sliding pipes to the pipe with a fixing tool, the leg spacing of each stepladder is determined with the cooperation of the stepladder spacing regulating member, and is made immovable.

この各脚立における脚間隔を定め、不動のもの
とするにあたつて、パイプへの滑動用短管の固定
位置を変え、脚立自体の高さを僅かながら変える
こともできる。 In determining the distance between the legs of each stepladder and making it immovable, the height of the stepladder itself can be slightly changed by changing the position at which the short sliding pipe is fixed to the pipe.

上記の如く、足場本体としての数基の脚立が一

軽快な移動が可能となる。 When it becomes necessary to move the scaffold assembled as described above to another work location, the leg ring body of each leg ring attached to the pipe for forming the stay pipe with wheels for connecting the stepladder. By pushing down the wheel support retaining rod that is supported by the wheel support rod and fixing it in place at the lower part of the leg wheel body, the mutual positional relationship of each component of the scaffold is maintained firmly, so the scaffold can be disassembled. Safe and nimble movement is possible using wheels supported by wheel supports that can change the direction of walking.
