摘要
Wherein the coupling connecting the elevator car door to the elevator hoistway door includes a pair of vanes, each end of each vane pivoted on a link connecting each vane to the other vane, the links being pivotally connected to the two vanes of the elevator car door So as to form a parallelogram. The vanes extend vertically between the four rollers rotating about the horizontal axles disposed at the top of the hoistway door and provide a coupling with rotational rigidity. The solenoid actuator moves one vane upwards to bring the parallelogram into the separated position. When the actuator is deactivated, the spring causes the parallelogram to spread out, allowing the vanes to engage between the rollers, and the two doors are connected together.
