Problems solved by technology

In addition, because it is difficult to control the hall door in the process of closing the car door, due to the speed of the car door, the hall door will collide with each other when closing
The resulting mechanical impact of the door and severe vibration and noise can make passengers uncomfortable and shorten the life of the elevator system
[0011] Therefore, the existing elevator sets the speed of the car door slowly to prevent the resulting mechanical collision and severe vibration and noise, which will lead to a reduction in elevator capacity and inconvenience to passengers getting on and off the elevator

Embodiment Construction

[0026] Preferred embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0027]Referring first to FIG. 5 , similar to the prior art, the drive motor 2 is installed on the car frame 1 . The drive motor 2 drives the drive pulley 4 via the belt 3 at a reduced rotational speed. Furthermore, the drive pulley 4 rotates a timing belt 6 connected to the driven pulley 5 . The left and right car doors 7, 7' are integrally suspended on the suspension plates 8, 8', and the suspension plates 8, 8' are movably suspended on the guide rails 9 installed on the car frame 1. Unlike the prior art, the suspension plate 8 of the car door 7 is not directly connected to the timing belt 6, but is connected to the timing belt 6 through a part of a clutch device which will be described below so as to be guided by the part. On the other hand, although not shown, the car doors 7, 7' are connected to each other by a single rope. When one door 7 moves, th...

Abstract

The invention discloses an improved elevator door system, which comprises a hall door, a car door, a motor providing rotational force to open and close the hall door and the car door, a power transmission device, a rack movable horizontally through the power transmission device, and A pinion gear that the rack meshes to rotate through the horizontal movement of the rack, a clutch device connected to the pinion gear to transmit or cut off power supplied to the hall door, and a door locking device that cooperates with the clutch device that transmits power , the door locking device is in a loose state where the hall door can move, and when the clutch device cuts off the power, the door locking device is in a locked state where the hall door is fixed.

Description

technical field [0001] The present invention relates to an elevator door system for opening and closing car doors and hall doors of each floor in an elevator system, and more particularly to an improved elevator clutch device for releasing the landing door lock before operating the car door Tightening device to reduce vibration and noise during opening / closing of car doors and hall doors, and to make the elevator move faster. Background technique [0002] As is known to those skilled in the art, an elevator system includes a car door mounted on an elevator car moving through the hoistway of a building, and a hall door mounted on each floor of the building In a hall leading to the well. Therefore, in order for passengers to get on and off the elevator, both the car door and the hall door must be opened. In addition, power must be required to open the car door and the hall door, and the elevator system uses only one drive source located in the elevator to open / close the car ...
