Description

Clutch structure of elevator car door {CLUTCH STRUCTURE OF ELEVATOR CAR DOOR}

The present invention relates to a clutch structure of an elevator car door, and more specifically, the position of a clutch device provided in the car door of an elevator can be selectively changed so that the clutch moves up and down the elevator car. It relates to a clutch structure of an elevator car door capable of preventing arbitrary interference with a door sill.

In general, elevator devices are installed in various types of high-rise buildings built for residential or business purposes to help passengers move in the vertical direction.In other words, elevator platforms are provided on each floor of the building and in the vertical direction inside the building. As a hoistway is formed, the elevator car moves up and down along the hoistway to move passengers boarding from each platform to the destination floor according to the passenger's button input.

In addition, the elevator car is provided with a car door that can be selectively opened and closed, and an elevator door is installed and provided at the entrance of each floor of the building to open and close in conjunction with the car door to allow passengers to get on and off the floor. do.

At this time, the car door provided on the side of the elevator car and the elevator door provided on each floor are configured to be operated integrally with one power medium for efficient operation of the device. For this purpose, the elevator including the car door and the elevator door The door is provided with a clutch device so that the car door and the landing door are connected to each other through a clutch device to be operated integrally while the elevator car is stopped on a certain floor.

In the elevator door structure as described above, the clutch provided on the car door side has a pair of substantially "┓" shape and "┏" shape, respectively, so that the clutch provided on the car door side can be smoothly engaged and operated. It consists of a bar-shaped member.

However, in the conventional clutch device provided on the elevator car door side, as a pair of members protrude toward the elevator door side, the elevator car is caused by various causes including vibration of the elevator car or the occurrence of minute imbalance. During operation of the vehicle, the corresponding member randomly contacts the door sill on the side of the boarding door, causing noise or causing damage or failure of the device.
