Is urged to move the belts 9a and 9b, and the belt grip 4
By fixing b to the belt 9b, these transmission devices 9
The sliding door 4 opens through. When the sliding door 4 is opened, the roller 5d is disengaged from the convex portion 6a, the movable member 5b is lowered by its own weight, and the parallel link 5c is displaced to the horizontal position. As a result, the movable member 5b approaches the fixed plate 5a, and the engaging device 9 grips the engaging element 10. When the sliding door 4 is opened, the roller 8a pivotally supported by the holding lever 8 is the urging body 8.
The sliding door 4 moves in the opening direction of the sliding door 4 over the chevron cam 7 against the biasing force of b. Further, when the sliding door 4 that has been opened is closed, the engagement device 5 and the holding lever 8 operate in the opposite manner to when the door was opened. As a result, the engaging device 5 does not hold the engaging element 10, and the roller 8a of the holding lever 8 is supported on the slope of the chevron cam 7 so that the sliding door 4 is moved by the urging force of the urging body 8b. It is urged toward the door.

た。In the conventional elevator door device as shown in FIG. 6, when the sliding door 4 is fully closed, the door opening force is generated by the weight of the link mechanism 12. Therefore, when the power supply to the elevator is cut off, there is a risk that the sliding door 4 will be opened by itself from the fully closed state due to the door opening force due to the weight of the link mechanism 12. And the inclination of the cam 12d is utilized to obtain the door closing holding force for holding the door fully closed. However, in order to smoothly open and close the door, it is necessary to avoid a rapid change in the urging force applied to the sliding door 4, and therefore the inclination of the cam 12d is naturally limited, so the spring elasticity of the urging body 11 is sufficiently increased. There was a need. As a result, it is necessary to improve the strength of the door device, which causes a problem of increasing the manufacturing cost of the device.

する。In the elevator door device thus constructed, when the sliding door 4 is fully closed, the roller 5d is supported by the recess 12e of the cam 12d, whereby both the movable member 5b and the fixed plate 5a are supported. The engaging element 10 is separated from each other and the engaging element 10 is arranged in a non-grasping state between them. Also, double link mechanism 1
2 indicates that the connecting point of the first link 12a and the second link 12b is more than the line connecting the pivot point of the first link 12a to the fixed body 3 and the pin 12c that pivotally connects the second link 12b to the sliding door 4. It is arranged so as to be located on the upper side. For this reason,
Due to the weight of the link mechanism 12, the first link 12a rotates clockwise around the pivot point of the first link 12a and the fixed body 3, and the second link 12b.
Is a motion that rotates counterclockwise around the contact portion between the recess 12e of the cam 12d and the roller 5d as a fulcrum, and a biasing force acts on the sliding door 4 in the door closing direction in the fully closed state. Occurs.

It works in the direction of pushing the link 12b. However, when the sliding door 4 is fully opened as shown in FIG. 2, it acts as an extending spring and acts in a direction to pull the second link 12b. Biasing body 13
FIG. 3 shows an enlarged view of the part of FIG. Since the urging body 13 is in the compressed state when fully closed, the urging force M 1 acts on the second link 12b counterclockwise, and the urging force causes the sliding door 4 to move.
The door closing force is generated. Further, when the sliding door 4 is fully opened, the urging body 13 is in a pulled state, so the second link 12
An urging force M 2 acts on b in the clockwise direction, and the urging force generates a door opening force of the sliding door 4.

開閉駆動作用を得ることができる。In the elevator door device constructed as described above, when the sliding door is fully opened, it is pulled by the urging body 14 so that
The lathe 5e presses the right inclined portion of the chevron portion 19a. When the sliding door 4 starts to open, the roller 5e is urged by the urging body 1.
Against the pulling force of No. 4, the right side inclined portion of the chevron portion 19a is pressed and the upper end of the chevron portion 19a is moved over. The parallel link 5c rotates counterclockwise around the contact portion with the engagement device 5, and the movable member 5b also moves at the same time.
It rotates counterclockwise around the contact portion between c and the engagement device 5. When the sliding door 4 is further opened, the roller 5e is moved to the mountain portion 1
It moves while pressing the left inclined part of 9a. Roller
When 5e descends from the left inclined portion of the chevron portion 19a, the movable member 5b and the fixed plate 5a are in a state of gripping the engaging element 10. After that, the roller 5e moves along the chevron cam 19 while the movable member 5b and the fixed plate 5a hold the engaging element 10. Before the sliding door 4 is fully closed, the roller 5e has the chevron portion 19b.
Of the movable member 5b and the fixed plate 5a, and the engaging element 10 is in the non-grasping state. Thereafter, the roller 5e moves on the upper end portion of the chevron portion 19b.
When the sliding door 4 is fully closed, the roller 5e is pulled by the urging body 14 so that the left inclined portion of the chevron portion 19b is pressed. Therefore, with the simple structure as described above, when the sliding door 4 is fully closed, the sliding door 4 is biased in the door closing direction.
When is fully opened, it is urged in the door opening direction, and a smooth opening and closing driving action of the sliding door can be obtained.
