Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheelchair escalator step transporting device which is capable of carrying steps of an escalator for wheelchairs and which is suitable for mounting or removing the steps.

[0002]

2. Description of the Related Art In recent years, escalators for wheelchairs have been tending to be newly installed, especially in public facilities and the like, so that users of wheelchairs can easily ascend and descend by escalators. The escalator for a wheelchair is connected endlessly among the steps driven endlessly.
By designing the cleat surfaces of the three steps on the same plane, the wheelchair can be placed on this plane with a margin.

By the way, the steps incorporated in such an escalator for wheelchairs have a special mechanism different from the steps of a general escalator, so that the weight thereof is heavy, and it is designed so that it can be mounted on, for example, an electric wheelchair. In the case of a wheelchair escalator step, the weight of the escalator is about 150 kg.

Therefore, it is not easy to carry out the work of carrying a step which is a heavy object and changing the posture thereof by human power alone at the installation site of the escalator for wheelchairs.
Therefore, conventionally, the step of packing the cleats in a predetermined posture with the cleat surface facing upward is carried on a trolley, and the packing is unpacked at the installation site.

In addition, at the time of inspection or repair of the wheelchair escalator, the removed step must be temporarily placed near the work site, but if the step is not supported, the cleat surface can be placed with the cleat surface facing upward. Therefore, conventionally, the removed step is turned upside down so that the cleat surface faces downward and placed on a trolley to temporarily store the step in a stable posture in the vicinity.

[0006]

However, in the above-mentioned conventional technique, when the steps in the packed state are carried to the installation site of the escalator for wheelchairs, the width of the packing material accommodating the step main body becomes the escalator entrance / exit. Since it is larger than the distance between the protruding left and right handrails, the packing step must be unloaded from the trolley in front of the handrail to unpack it. There was the complexity that the steps had to be carried by human power alone. In particular, in the case of an escalator step for an electric wheelchair, the step, which weighs about 150 kg, must be carried by four people, so that the work efficiency is extremely poor and the physical burden is heavy.

Further, as described above, conventionally, when the escalator for wheelchair is inspected or repaired, the removed steps are turned over and temporarily stored on the trolley, but the heavy steps are turned over and placed on the trolley. It is not easy to return to the original posture, and it requires manual labor and physical burden.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a carrying device capable of efficiently carrying and temporarily storing a step associated with attachment / detachment work of an escalator step for wheelchairs. .

[0009]

DISCLOSURE OF THE INVENTION The above-mentioned object of the present invention is that the width dimension of the escalator for wheelchairs is substantially the same as that of the escalator for wheelchairs. A horizontal holding member that is attached to the front of the step and is supported on the cargo bed section in order to hold it upward, and a roller that is protruded below the cargo bed section and is rotatable. It is achieved by In addition to this, a holding member that holds the step placed on the luggage carrier in a predetermined posture with the cleat surface facing upward and maintains the posture of the step on the luggage carrier, More preferably, the roller is provided with a stopper capable of preventing rolling.

That is, since the luggage carrier portion provided with the protruding rollers can function as a carriage having a width dimension substantially equal to that of the step of the wheelchair escalator, the horizontal holding member is mounted on the luggage carrier portion. By mounting the above steps, the steps can be transported or temporarily stored in a predetermined posture with the cleat surface facing upward. Therefore, when transporting the mounting step to the installation site, the step can be transported to the back of the escalator entrance / exit by inserting the loading platform between the left and right handrails. When the steps are temporarily stored, the steps can be placed on the loading platform without being turned over, so that any work can be efficiently performed.
