Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving device in which a part of a step can be moved and the position thereof can be freely changed while the part of the step is being used while being used for various works such as a wall surface. The present invention relates to a free work platform.

[0002]

2. Description of the Related Art In general, a very complicated operation of moving a step on a step of this kind, such as moving down from a step to a place to be used every time, is performed.

[0003]

In the conventional platform, when it is installed at the place of use, it is necessary to go down once to the place where it is desired to move, such as a lateral direction or a back direction, and move with the platform. There was a problem. The present invention
In order to solve the above-mentioned conventional problems, it has an opposing circular tread and an intermediate tread, and by riding on one circular tread, the other circular tread moves movably together with the intermediate tread,
It is an object of the present invention to provide a movable work platform that can easily move a use position while being on a tread plate and that solves troublesome labor and work.

[0004]

In order to achieve the above-mentioned object, in the moving step platform of the present invention, the step platform main body is provided with a circular step platform opposing the upper platform section and an intermediate step platform corresponding thereto. A support rod is provided below the intermediate tread plate, and a horizontal turning horizontal plate is attached to the lower end of the support rod. Bearing portions are provided at both ends of the rotating horizontal plate, and a lifting / lowering rod provided below the circular tread is inserted into and suspended from the bearing portions. The lower part of the elevating support rod is inserted into the guide rod, and a lower caster is inserted under the guide rod via a spring. Further, a support leg is provided on the outer periphery of the guide rod.

[0005]

When the step body (1) constructed as described above is not normally used, it is slightly protruded downward from the caster (12) or the support leg (13) by a spring (11). The step body (1) can be freely moved by the casters (12). For example, when performing work such as painting the step body (1) toward the wall surface, when the step body (1) is put on the step body (1), the lifting rods (9) and (9) are lowered, and the casters (12) and (12). ) Contracts the springs (11) and (11) and rises, the support legs (13) and (13) touch the ground and are stable, and can work as a work platform.
Next, when it is desired to move the step platform main body (1) to the right side as viewed in FIGS. 1 and 2, for example, it moves only to the upper surface of the circular step board (3), and the opposite circular step board (2) moves. The lower caster (12) is pushed out by the repulsive force of the spring (11), and the support leg (13) is movable away from the ground. Therefore, the circular tread (2) and the intermediate tread (5) are arranged along the outer periphery of the circular tread (3) along the outer periphery of the circular tread (3) using the bearing (8) provided below the circular tread (3) as a support shaft. ) Moves to the right side of the circular tread (3) and can be freely moved as a stepping platform by operating in a riding state and can be used as a working platform. When the user wants to move the circular tread plate to the opposite side and use it, the circular tread plate (3) may be moved in the opposite direction and used repeatedly as described above. When the step body is not used, both springs (11) and (11)
The casters (12) (12) can move freely in a protruding state.

[0006]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a stepping body according to an embodiment of the present invention; FIG. Is located. An intermediate tread plate (5) having a shape that is always rotatably joined to the circular outer periphery is installed at a slightly horizontal position between the circular tread plate (2) and the circular tread plate (3). The intermediate tread (5)
Is provided with a support rod (6) at the lower part and a support rod (6).
Is mounted on the pivoting horizontal plate (7).

[0007] Bearing portions (8) and (8) are formed at both ends of the turning horizontal plate (7). The bearings (8) and (8) include:
The lifting support rods (9) (9) provided on the lower surfaces of the circular treads (2) and (3) are inserted. The bearing (8) (8)
The guide rods (10) and (10) are provided below.

The lower ends of the elevating support rods (9) and (9) are inserted into the guide rods (10) and (10) so that the lower ends thereof can be slightly lifted and lowered, and helical springs (11) and (11) are provided at the lower ends. To store. Casters (12) (12) for swinging and the like are housed in the lower parts of the springs (11) (11) so as to be able to move up and down. In addition, support legs (13) (13) made of a circle or the like are provided on the outer periphery of the guide rod (10), and the support legs (13) (13) are provided with the circular treads (2) and (13). If a load from an operator or the like is involved in 3), casters (1
2) (12) is to stably contact the ground by adjusting the contraction of the springs (11) and (11). Code (15)
Shows a mounting portion for supporting the lower end of the support rod (6) on the rotating horizontal plate (7).

[0009]

As described above, according to the movable work platform of the present invention, the platform can be freely moved in the left-right direction and the rear direction while the platform is on the upper portion of the work platform. There is an effect that the troublesome trouble of getting down and moving is not involved. And, depending on the intermediate stepping plate located between the stepping body and the opposing circular stepping plate, along the outer periphery of the circular stepping plate on which the other circular stepping plate and the intermediate stepping plate are riding on any circular stepping plate. Due to the effect of being able to rotate and the supporting rod and the rotating horizontal plate provided at the lower part of the intermediate tread, the lifting and lowering rod provided at the lower part of the opposing circular treads serves as a bearing part to improve the rotating action. effective. In addition, the lower part of the lifting rod is inserted inside the guide rod, and the casters are installed under the springs at the lower part, so when riding on a circular tread, the springs contract firmly and the casters rise. In this state, the support legs are in contact with the ground and the stability can be maintained, and when not on a circular tread, the casters protrude downward from the support legs due to the repulsive force of the spring, and can be reliably rotated. . Further, when the step platform body is not used, there is a convenient effect that the casters can be freely moved by the casters.
