Abstract

The present invention relates to a coupling device for an elevator door, and the coupling device for elevator doors according to the prior art has a long coupling time and structurally high noise because the cam roller performs a coupling operation while guiding the cam along the cam. It causes excessive vibration, and the hatch door must be closed before the car door is completely closed, and thus, additional devices are required, and this additional device causes a problem of degrading the performance of the elevator door system. In order to solve this problem, the coupling device for an elevator door according to the present invention is fixed to install two fixed vanes on the hatch door panel, and to install a roller link that can be in close contact with the fixed vanes in the car door panel and In addition, by installing and fixing a roller link driving device such as an air cylinder or a magnetic coupler to the card door panel so as to contract and expand the roller link, the coupling time is reduced and noise and vibration are reduced. In addition, if the roller link driving device is driven before the car door is completely closed, the hatch door is closed first, and since the additional device is not necessary to close the hatch door first, it is possible to reduce the performance of the elevator door system. You can expect the effect to prevent.
