Stationary actuator moving vane elevator car door coupling |
摘要 |
A coupling for causing an elevator car door to engage an elevator hoistway door includes a pair of vanes, each end of each vane pivoted on a link connecting it with the other vane, the links being disposed for rotation between said two vanes on an elevator car door thereby forming a parallelogram. The vanes extend vertically between four rollers which rotate about horizontal axles disposed at the top of the hoistway door, and which provide rotationally stiff coupling. A solenoid actuator can move one vane up to cause the parallelogram to shrink, into an uncoupled position. When the actuator is disenergized, a spring causes the parallelogram to spread so that the vanes are wedged between the rollers and the two doors are coupled together.
