点があつた。 In recent years, gable or semi-cylindrical roofs, glass,
Many are made of aluminum or other panels. A movable ladder is required when installing panels on these roofs and cleaning them after construction. And, in conventional mobile ladders,
As seen in Japanese Patent No. 52-68630, wheels were mounted on a bracket and the bracket was attached directly to the upper end of the ladder frame. For this reason, it is necessary to prepare and mount brackets with various mounting angles for roofs with different inclination angles, which has the drawback of requiring a large amount of cost to manufacture the ladder.

とを目的とする。 The present invention aims to solve the above-mentioned drawbacks, and a cylindrical pipe is attached to the upper and lower ends of a frame of a ladder, and a cylindrical fitting part of a bracket to which a wheel is attached is fitted to the cylindrical pipe. By installing a ladder, even if the ladder is installed on a roof with a different angle of inclination, by changing the installation angle of the bracket that fits on the cylindrical pipe, at least one wheel can always be installed so that it faces almost vertically. The purpose is to provide a mobile ladder that can be used.
以下本発明の実施例を図面に基いて説明する。 Embodiments of the present invention will be described below based on the drawings.

間隔で接触することとなる（第９図参照）。 Figures 3-11 show details of the mobile ladder. The ladder 5 is formed by fixing a step 9 to a pair of frames 8, 8' made of pipes such as aluminum, and a cylindrical pipe 10 is welded to the upper end of the ladder 5, and a cylindrical pipe 11 is welded to the lower end of the ladder 5. Brackets 1 are attached to the cylindrical pipes 10 and 11, respectively.
2, and fix it with a set screw 13 or the like. The bracket 12 consists of a cylindrical fitting part 14, a pair of legs 15, 15' connected to the fitting part 14, and reinforcing ribs 16, 16', with the legs 15, 15' facing in the vertical direction. The wheel 17 and the wheels 18 and 19 are connected to the shaft 2 at an angular interval of 120 degrees from the wheel 17.
0, 21, and 22 so as to be rotatable. Therefore, a rail 6 with a circular cross section such as a cylindrical pipe is provided on the upper side of the roof 2, and three wheels 17, 1
8 and 19 come into contact with the circumferential surface of the rail at an angular interval of approximately 120 degrees (see FIG. 9).

で、はしご５を軽く移動できる。 The configuration of the mobile ladder 4 has been explained above,
Looking at its function, the rails 6 and 7 provided on the upper and lower sides of the curved and sloping roof 2 are mounted on the bracket 12, and the wheels 17, 18, 19 are used.
When the ladder 5, which is held in contact with each other at 120 degree intervals from three sides, is pushed in the direction of arrow A or B in FIG. 2, the ladder 5 moves easily. At this time, if the wheels 17 attached to the bracket 12 provided at the upper end of the ladder 5 are made to face almost vertically, the load of the ladder 5 will be applied to the wheels 17, and the wheels 18 and 19 will only act as a guide. So, you can easily move ladder 5.

した状態にあるようにしている。 Further, the circular rail 6 is provided on the upper side of the roof, and is supported by the support part 32 of the joint 23 (FIGS. 8 and 9).
It is necessary to prevent the wheel 19 from hitting the rail 6, and it is also necessary that the wheel 17 faces the substantially vertical direction and contacts the rail 6. On the other hand, roofs have various inclination angles, and ladders are installed with different inclination angles depending on the inclinations. In this embodiment, a bracket 12 is fitted onto the cylindrical pipe 10 attached to the upper end of the frames 8, 8' of the ladder 5.
The rail 6 and bracket 12 are always arranged vertically.

３１が軸３２により回動自在に取付けてある。 In the above embodiment, a bracket 12 having three wheels 17, 18, 19 was provided at the lower end of the ladder 5, but a bracket 12 having three wheels 17, 18, 19 may be provided as shown in FIG. FIG. 12 shows the vicinity of the lower end of the ladder 5 when the lower part of the curved and sloping roof 2 is a flat surface, and the flat surface itself becomes a rail, that is, the rail is a flat surface. A cylindrical fitting portion of a bracket 30 is fitted into the attached cylindrical pipe 11, and a wheel 31 facing in the vertical direction is rotatably attached to the bracket 30 by a shaft 32.
また、上記実施例でははしご５の上端に設けた

２に取付けるとよい。 Further, in the above embodiment, one wheel 17 facing the vertical direction is mounted on the bracket 12 provided at the upper end of the ladder 5.
However, when the ladder 5 is large and heavy (for example, over 150 kg), two to several wheels 17 facing vertically are attached to the bracket 1 in series.
It is recommended to install it on 2.
更にまた移動ばしごは、第１３図に示す如く、
屋根が切妻状で、その一側方の平面状で傾斜した
屋根に設けられる場合も彎曲状で傾斜した屋根に

という効果を奏する。 Although the embodiments of the present invention have been described above, the present invention has the following features: (1) Since wheels are provided at the upper end and the lower end of the ladder, facing approximately vertically,
The load of the ladder is supported by these wheels, and the other wheels installed at the top of the ladder contact the circumferential surface of the circular rail and only act as a guide, making it possible to move the ladder easily. ) The bracket is attached by fitting the cylindrical fitting part of the bracket to the cylindrical pipes attached to the upper and lower ends of the ladder, so even if the ladder is installed on a roof with a different angle of inclination, the cylindrical pipe can be attached to the bracket. By adjusting the mounting angle of the fitting bracket, the wheel can be installed so that it always faces almost vertically. Therefore, it is possible to install a cylindrical pipe of the same thickness and a cylindrical fitting part that fits into the same diameter. By preparing a bracket having the following structure, a movable ladder that can be installed on roofs with various inclination angles can be manufactured at a low cost.
