BACKGROUND OF THE INVENTION With the development of transportation systems, railway station platforms and the like have been installed higher or lower than ground level, and as a result, an increasing number of stations have installed escalators to improve passenger convenience.

However, it is extremely difficult for wheelchair users to use escalators, and even if they get on the escalator with an attendant, they will not be able to place the wheelchair horizontally on top of the first step of the escalator; Since the user has no choice but to straddle steps and tilt the wheelchair, there is a high possibility that the wheelchair will fall, which is extremely dangerous.

Additionally, escalators with a special structure that carry both wheelchairs and general passengers cannot often be installed due to the structure of station buildings, etc. On the other hand, there are places where escalators exclusively for wheelchairs are installed, but they are not escalators for general users. The disadvantage is that it must be installed separately.

Therefore, in order to eliminate the above-mentioned drawbacks, the present applicant has filed a patent application separately from this invention for a wheelchair auxiliary trolley for escalators having the structure shown in Figs. 1 to 3 (hereinafter referred to as This patent application is referred to as a separate application).
