Description

Elevator door {ELEVATOR DOOR}

The present invention relates to an elevator door, and more particularly, by configuring the hanger member connecting the arm of the elevator door drive mechanism to the door panel so that it is not easily damaged by the impact, the detachment of the door panel is prevented and accordingly The present invention relates to an elevator door with improved safety.

Normally, an elevator for carrying a person or cargo up and down is provided with an elevator door 1 as shown in FIG. 1, which is installed in an elevator car (not shown) to open and close the elevator car.

The elevator door 1 is connected to the drive shaft 3 fixed to the upper frame 2 of the elevator car and the rotation shaft of the drive motor 3 by a belt 4 so as to reduce the rotational speed of the drive motor 3. A belt pulley 5 to be driven is provided. In addition, a chain pulley 8 is connected and driven by the belt pulley 5 and the chain 7, and the chain pulley 8 is provided with two first links 9a and 9b and the first link. Two second links 10a and 10b connected to the ends of 9a and 9b, respectively, are provided. Arms 13a and 13b pivotably connected to the ends of the second links 10a and 10b are fixed to the hanger member 12 of the door panel 11. Arms 13a and 13b are the aforementioned drive motor 3, belt 4, belt pulley 5, chain 7, chain pulley 8, first link 9a, 9b and second link ( An elevator door drive mechanism for opening and closing the door panel 11 together with 10a and 10b is configured.

Referring to FIG. 2, a hanger member 12 having a generally flat shape is attached to an upper portion of the door panel 11, and the hanger member 12 has a lower end bent in a 'b' shape. It is against the upper end and fixed to the hanger member 12 by bolts 18. The hanger roller 14 is provided in the upper side of the hanger member 12, The said hanger roller 14 slides along the guide rail 15 provided in the frame 2 of the said car, and it is arm 13a, 13b. When the door panel 11 is moved left and right, the door panel 11 is assisted to be easily moved. On the other hand, the rotary roller 16 is attached to the hanger member 12 below the guide rail 15 to assist the connection between the guide rail 15 and the hanger roller 14.

The operation of the elevator door (1) configured as described above is as follows. First, when the drive motor 3 is driven, the driving force is transmitted to the first links 9a and 9b along the belt 4, the belt pulley 5, the chain 7 and the chain pulley 8. The energized first links 9a and 9b transmit their forces to the second links 10a and 10b via linear motion, and the second links 10a and 10b then move the connected arms 13a and 13b to the left and right. Move to. Accordingly, the door panel 11 is opened and closed by the hanger roller 14 of the hanger member 12 fixed to the arms 13a and 13b sliding along the guide rail 15.

However, the hanger member 12 of the elevator door 1 as shown in FIG. 2 has the following disadvantages. Typically, some of the people boarding the elevator sometimes lean on the elevator door 1, ie the door panel 11. If this is repeated, the door panel 11 is subjected to lateral pressure from the left side of FIG. Such pressure is concentrated at the bent portion of the hanger member 12 and thus the portion is deformed.

3 shows an example in which the hanger member 12 is deformed by such repeated transverse pressure. When the hanger member 12 is deformed as shown, the alignment between the hanger roller 14, the guide rail 15, and the rotation roller 16 is disturbed, so that the guide rail 15 is caused to hang the hanger roller 14 and The possibility of departure between the rotary rollers 16 occurs. In addition, even if separation does not occur, the connection between the guide rail 15 and the rollers 14 and 16 becomes poor. Then, when the door panel 11 moves, friction may occur between them, and the opening and closing of the door panel 11 may be poor, or the door panel 11 may not operate. In addition, when the lateral pressure is severe, the fixing between the hanger member 12 and the door panel 11 is poor because the bolts 18 holding the hanger member 12 and the door panel 11 are at least partially loosened. Can be done. In addition, opening and closing of the door panel 11 can be made poor, and operation of the door panel 11 can be stopped severely.

In such a case, the hanger member 12 must be replaced because it is very difficult to correct the deformation through repair, and the replacement of such parts would increase the cost associated with elevator maintenance. Moreover, when repair and replacement are necessary, the hanger member 12 must be detached from the door panel 11 by releasing the bolt 13 securing the hanger member 12 to the door panel 11. There is also a disadvantage that this operation is not easy because is attached to the top of the door panel 11.

Therefore, one object of the present invention is to remove the bent portion of the hanger member connecting the elevator door drive mechanism to the door panel to prevent concentration of pressure in the bent portion, thereby deforming the hanger member and accompanying opening and closing of the door panel. And it is to provide an elevator door that can prevent the failure.

Another object of the present invention is to support the hanger member and to increase the fixing between the hanger member and the door panel by inserting a reinforcement member between the hanger member and the door panel in the elevator door.
