Abstract (en)

An endless chain36 is wrapped around an upper sprocket wheel 34 disposed on an upper floor 32 and a lower sprocket wheel 42 disposed on a lower floor 31, and a plurality of stepboards 37 are connected to the chain 36. Each stepboard 37 has a riser 38 connected to one end thereof on the lower floor 31 side to be angularly displaceable. In a transport region S5, the riser 38 is placed in a projection position extending downward. In a lower circulating region S2, the riser 38 is folded to be substantially parallel to the stepboard. Thus, the escalator system 30 may be made thin. Link means 80 is disposed between each stepboard 37 and riser 38. Guide members 100 are disposed in the vicinity of an upper end of the escalator system 30. The link means 80 is displaceable by guiding action of the guide members, whereby the riser 38 moves in a folded state to the lower circulating region S2. <IMAGE>
