An eccentric crankshaft is connected to a rotary driving device, and a rocking unit is connected to the eccentric crankshaft. Pin roller rolling gear teeth, each having a trochoid tooth-shape, are provided in the rocking unit. When the rocking unit rocks in accordance with eccentric rotation of the eccentric crankshaft, the trochoid shape of the pin roller rolling gear teeth meshes with pin rollers and thus gives a thrust to the pin rollers, thereby driving footsteps.

Passenger conveyor device

A conveyor apparatus according to the present invention comprises a tread guide rail which is provided on a structure , and a plurality to treads which moves along the tread guide rail . The plurality of treads are connected by a chain having pin rollers 5 . An eccentrically rotatable eccentric crank shaft is connected to a rotation drive unit . The eccentric crank shaft is connected to an oscillating body which oscillates in accordance with the eccentric rotation of the eccentric crank shaft . The oscillating body is provided with pin roller rolling teeth having a trochoid tooth profile for giving thrust to the pin rollers in accordance with the oscillation of the oscillating body

Conveyor device

A dual-purpose escalator for a wheelchair including a plurality of steps linked in an endless form and a main-frame having a running path for the steps. The steps include a plurality of specialized steps for loading a wheelchair. The escalator further includes an activating apparatus provided on the running path for causing the specialized steps to alter a configuration thereof to a first state for a wheelchair loading operation mode or to restore the configuration to a second state for normal operation mode. Each of the specialized steps includes a toothed rotor. The activating apparatus includes an engagement member for engaging with the toothed rotor. Each of the toothed rotors is rotated by engaging with the engagement member for causing one of the specialized steps to alter the configuration to the first state when the steps are running in the running path in the wheelchair loading operation mode, respectively. The engagement member includes a base and a plurality of pins set in parallel on the base at a specified pitch for engaging with the toothed rotor. The pin engaging firstly with the toothed rotor is set on the base so as to be capable of displacement from the toothed rotor.

Dual-purpose escalator for wheelchair

An escalator is arranged such that a first special step having a movable footplate capable of rising and falling is combined with a second special step adjacent to the upstream side of the first special step and having a projectable and retractable lift mechanism. The projectable and retractable lift mechanism supports the movable footplate of the first special step in part of a plurality of running steps provided endlessly in a line. When mounting a wheelchair, the movable footplate runs along the inclined path area with the movable footplate supported at the same height as the second special step by operating the lift mechanism in the horizontal path area of the travel path. The movable footplate ensures a rearward footplate dimension sufficient to carry the wheelchair. Accordingly, the wheelstops for the front wheels of the wheelchair are made to project, thereby better defining the wheelchair carrying position and improving the safety and shortening the time taken when mounting and transporting a wheelchair.
