Claims

[Scope of utility model registration request]

The main frame is arranged in an arc shape and inclined in the horizontal projection plane, and has an outgoing path on the top side, a reversing part on the longitudinal end, and a return path on the bottom side, forming an endless conveyance path. A large number of steps arranged in a fan shape in succession on the conveyance path and guided along the conveyance path, a step shaft extending in the width direction of each step, and a step shaft provided at the inner end of the step shaft. an inner drive roller that rolls on a chain and an inner drive rail; an outer drive roller that rolls on an outer chain and an outer drive rail provided at the outer end of the step shaft;
a drive presser rail that supports the outer drive roller from above;
a side roller that is guided by the outer drive rail or the drive presser rail and supports the load in the direction of the center of the circular arc of the conveyance path of the steps; - a small chain wheel disposed in the reversing section and around which the inner chain is wound; The main sprocket is located inside the circular arc of the transport path of the small chain wheel and is connected to the drive sprocket and the drive chain to drive both chain wheels. a ratchet sprocket arranged outside the arc of the chain wheel conveyance path and rotating together with both chain wheels; a shoe lever having a base end pivotally connected to a braking mechanism, a distal end pivotally connected, and a shoe at the distal end slidingly in contact with the drive chain; The shoe lever is connected to the shoe lever at a certain angle in its swinging direction, and swings when the shoe lever swings due to breakage or abnormal elongation of the drive chain, and its tip is locked to the ratchet sprocket for braking. The ratchet sprocket has a diameter smaller than the vertical distance between the outer drive rail on the outbound trip and the drive presser rail on the return trip, and the outer drive rail and the drive presser rail are supported by the main frame via a bracket, and A curved escalator characterized in that the shoe lever is provided with a lever having a weight at its tip to increase the rotational moment of the shoe lever.
