Description

  The present invention relates to a wheel stopper structure for preventing movement of a transport vehicle in which left and right wheels can turn.

  Conventionally, when a passenger rides on a bus together with a stroller, an auxiliary belt attached to a seat in a wheelchair space of the bus is tied to the stroller to prevent the stroller from moving while the child is on the stroller. However, it is necessary to attach and detach such an auxiliary belt to and from the stroller by the passenger, and it is difficult to carry out the attachment and detachment work in the car where the passenger shakes, and it is necessary to report to the crew when the usage of the auxiliary belt is unknown. There is a problem that the scheduled service is hindered. In addition, the movement of the stroller cannot be completely blocked by the auxiliary belt alone, and there is a problem that the stroller must be supported by the passenger while the bus is running with the stopper on the wheel of the stroller. In addition, since the wheel of the stroller is not configured to be stopped by the auxiliary belt, there is a problem that the movement of the stroller cannot be stably prevented only by the auxiliary belt. In order to solve such problems of the conventional auxiliary belt, a wheel stopper structure for safely stopping the stroller has been proposed.

  The conventional wheel stopper structure forms a recess notch in a step of a passenger conveyor (see, for example, Patent Document 1). In such a conventional wheel stopper structure, a recess notch is formed linearly in the width direction of the passenger conveyor step, and the front and rear wheels of the stroller are fitted into the recess notch to restrict the movement of the front and rear wheels of the stroller. doing.
