Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension device for a moving wall.

[0002]

2. Description of the Related Art Generally, a suspension vehicle that runs along rails installed on a ceiling is attached to the upper part of a moving wall used in museums, museums, and various exhibition halls. Is configured so that it can be moved by human hands.

However, in such a conventional moving-wall suspension vehicle device, two pieces are provided on each side of the base of the suspension vehicle for suspending the moving wall so that good traveling performance can be ensured. Alternatively, a total of four or six wheels, three each, are arranged at a height in contact with the same plane, and left and right paired wheels are rotatably pivoted about the same horizontal axis. And the load of the moving wall was supported by these wheels.

[0004]

However, in the above-described suspension vehicle having four wheels, when the suspension vehicle passes through the seam of the rail, a pair of left and right wheels on either side of the front and rear sides are loaded. There is a drawback in that the vehicle is rattled while it is being supported by being simultaneously fitted into the gap between the rail joints. In particular, when the gap between the joints is relatively wide at 1 mm to 2 mm, a pair of left and right wheels are fitted in the gap to prevent the vehicle from traveling, and an extremely large force was required for restarting. .

Further, in recent years, the weight of the moving wall has increased to about 2 tons, 3 tons or 10 tons with the increase in size of the moving wall, and when such a heavy moving wall is suspended,
Once the wheels were fitted into the gaps between the rail joints, the moving wall could not move.

Further, in the suspension vehicle having the above-mentioned six wheels, when the pair of left and right wheels at the front end or the rear end reach the joint of the rails, the other four wheels will bear the full load. However, in this state, the balance in the front-rear direction becomes unstable, and there is a drawback in that the suspension vehicle tilts forward or backward to cause rattling in traveling.

Therefore, the present invention eliminates the above-mentioned drawbacks and suspends a moving wall having an extremely large weight,
An object of the present invention is to provide a suspension vehicle device for a moving wall that can travel smoothly and smoothly not only on rails but also on rail joints.

[0008]

In order to achieve the above-mentioned object, a suspension vehicle device for a moving wall according to the present invention comprises a suspension vehicle main body that runs along a hanger rail while having a base portion for suspending the movement wall. A first main wheel and a second main wheel are rotatably mounted around a first horizontal axis and a second horizontal axis parallel to the front and rear of one side surface of the base section, and the base section is provided. The third main wheel and the fourth main wheel are rotatably mounted around the third horizontal axis and the fourth horizontal axis parallel to the front and rear of the other side surface, and further, the first horizontal axis and the third horizontal axis are attached. The horizontal axis is displaced forward and backward, and the second horizontal axis and the fourth horizontal axis are displaced forward and backward.

[0009]

When the suspension vehicle main body passes through the joint of the hanger rail, the first main wheel and the third main wheel, which correspond to the left and right, pass separately over the gap of the joint of the hanger rail. Similarly, the second main wheel and the fourth main wheel, which correspond to the left and right, pass separately over the gap of the seam of the hanger rail.

During this passage, the first main wheel, the second main wheel and the third main wheel
When any one of the main wheel and the fourth main wheel is on the gap of the seam, the other three main wheels always come into contact with the hanger rail and apply a load. Therefore, the suspension vehicle body easily and smoothly crosses the seams of the hanger rails.
