Description

Elevator door departure prevention structure

The present invention relates to an elevator door departure prevention structure of the elevator, and more particularly, to prevent the departure of the elevator door departure to increase the door coupling force of the closed state to prevent the opening of the elevator door by the external force and the occurrence of accidents caused by this It's about structure.

In general, boarding doors are installed in places where human contact is possible more directly than any part of the elevator, and is exposed to mischief and abnormal accidents of passengers.

Referring to FIG. 1, the elevators are provided with landing doors LD and RD, and the connecting doors 400 are connected to the upper doors of the elevator doors LD and RD.

In addition, a shoe 100 is formed below the landing doors LD and RD, and a seal 200 for inserting and guide the shoe 100 is installed in the lower part of the boarding area.

Therefore, the opening and closing operation is performed by the operation of the connecting plate 400 and the guide operation of the shoe 100 and the seal 200 when the lifting doors LD and RD are opened and closed by driving the landing door device.

That is, the connecting plate 400 is connected to each other by the wire 300, etc. in the landing door device to move one door (LD) is opened by receiving a force transmitted to the wire 300 connected to the other door (RD) or The closing structure or each connecting plate is driven and operated, and when closed, the upper part is fixed to the door connecting plate 400 and the door connecting plate 400 is connected to the wire 300, but only for left and right movements. Only when interlocked, when the impact on the front bottom of one door (LD) the other door (RD) has no effect on the rigidity or mass to support the pushing force and the lifting force.

Therefore, as shown in FIG. 2, when abnormal impact occurs due to an unavoidable accident on the landing doors LD and RD (arrows), the warpage is greatly generated when the shocked door does not have sufficient rigidity. There is a problem that the shoe 100 that serves as a guide of the lower part is separated from the seal 200.

Therefore, as shown in FIG. 2, when abnormal impact occurs due to an unavoidable accident on the landing doors LD and RD (arrows), the warpage is greatly generated when the shocked door does not have sufficient rigidity. The shoe 100 serving as a guide of the lower portion is separated from the groove 210 of the seal 200 occurs.
