Description

Elevator door equipment

According to the present invention, the car door and the landing door move while the car side engaging device provided on the car door and the landing side engaging device provided on the landing door are engaged with each other. The present invention relates to an elevator door device that opens and closes an elevator doorway.

Generally, in an elevator door device, a car-side engaging device is provided at a car door that opens and closes a car doorway, and a landing-side engaging device is provided at a landing door that opens and closes a hall doorway. The car-side engaging device and the landing-side engaging device can be engaged with each other in the horizontal direction when the car is stopped at the landing. The landing door is moved in the horizontal direction together with the car door when the car engaging device and the landing engaging device are engaged with each other. The car doorway is opened and closed by the movement of the car door in the horizontal direction, and the landing doorway is opened and closed by the movement of the landing door in the horizontal direction.

Conventionally, in order to suppress the shaking of the landing door with respect to the car door when the landing door is moved together with the car door, the car-side engagement device has a pair of blades and widens the interval between the blades. Thus, an elevator door device that holds the landing-side engagement device has been proposed. Each blade is attached to a parallel link rotatably provided on the car door. One blade is connected to a swinging member rotatably attached to the upper part of the car door via a connecting rod. The swinging member is rotated by contacting with a cam fixed to the upper part of the car doorway while moving together with the car door. Each blade is displaced in a direction approaching each other while rotating the parallel link by pulling up one blade by the rotation of the swing member. The landing-side engagement device is held by the car-side engagement device in a state where the distance between the blades is widened. Further, the holding of the landing-side engagement device by the car-side engagement device is released when one blade is pulled up and the blades approach each other (see Patent Document 1).

Japanese Utility Model Publication No. 62-98678

However, in the conventional elevator door device, the rotating directions of the swing member and the parallel link when one blade is pulled up are opposite to each other. Therefore, the swinging member and the parallel link are rotated in a direction in which the inclination of the connecting rod changes greatly. Therefore, if the position of one blade with respect to the swing member is slightly deviated from the design position, the amount of rotation of the parallel link with respect to the amount of rotation of the swing member deviates significantly from the design value, and each blade is designed. It can no longer be displaced along the street.

When installing the elevator door device, the position of each blade may be adjusted in the horizontal direction with respect to the landing-side engagement device. When such an adjustment is made, the position of one blade is displaced with respect to the swinging member. Therefore, in a conventional elevator door device, the position of the swinging member is also adjusted to the position of the one blade. Will have to do. Therefore, it takes time to install the elevator door device.

The present invention has been made to solve the above-described problems, and an object of the present invention is to obtain an elevator door device that can be easily installed.

An elevator door device according to the present invention includes: a car door that opens and closes a car doorway by moving toward the front of the car doorway; a fixed blade fixed to the car door; and a link support shaft provided in the car door. A pivot link that is pivotable about the center, a grip position that is provided on the pivot link and has a predetermined distance from the fixed blade in the moving direction of the car door, and a release position that is farther from the fixed blade than the grip position A car-side engagement device having a movable blade that is displaced according to the rotation of the rotation link, a rotation lever that is rotatable about a lever support shaft provided on the door of the car, The car has a connecting member for interlocking the moving lever and the turning link, and a cam fixed to the car doorway and for turning the turning lever that is moved together with the car door, and closes the car doorway.

The rotation lever 34 is rotatable about a hanger attachment shaft (lever support shaft) 37 provided on the door hanger 7. The hanger mounting shaft 37 is disposed in parallel with the first panel mounting shaft 23. In this example, the shape and size of the rotating lever 34 are the same as the shape and size of the drive link 20.

The intermediate part of the rotation lever 34 is attached to the hanger attachment shaft 37. A roller shaft 38 is provided at one end of the rotation lever 34, and a lever connection shaft 39 is provided at the other end of the rotation lever 34. The roller shaft 38 is positioned on the door closing side with respect to the hanger mounting shaft 37, and the lever connecting shaft 39 is positioned on the door opening side with respect to the hanger mounting shaft 37. The roller shaft 38 and the lever connection shaft 39 are arranged in parallel with the hanger mounting shaft 37, respectively.

One end of the connecting rod 35 is rotatably attached to the link connecting shaft 26, and the other end of the connecting rod 35 is rotatably attached to the lever connecting shaft 39. That is, the connecting rod 35 is rotatably connected to the drive link 20 via the link connecting shaft 26 and is connected to the rotating lever 34 via the lever connecting shaft 39 so as to be rotatable. As a result, the direction of rotation of the drive link 20 around the first panel attachment shaft 23 and the direction of rotation of the rotation lever 34 around the hanger attachment shaft 37 are the same direction.

The distance between the link connecting shaft 26 and the lever connecting shaft 39 is the same as the distance between the first panel mounting shaft 23 and the hanger mounting shaft 37. The distance between the link connection shaft 26 and the first panel attachment shaft 23 is the same as the distance between the lever connection shaft 39 and the hanger attachment shaft 37. Accordingly, a parallelogram having four apexes of the first panel mounting shaft 23, the link connecting shaft 26, the lever connecting shaft 39, and the hanger mounting shaft 37 is formed between the drive link 20 and the rotating lever 34. .

The distance between the roller shaft 38 and the hanger mounting shaft 37 is the same as the distance between the blade mounting shaft 25 and the first panel mounting shaft 23. Further, the distance between the roller shaft 38 and the blade mounting shaft 25 is the same as the distance between the hanger mounting shaft 37 and the first panel mounting shaft 23. Accordingly, a parallelogram having four apexes of the first panel mounting shaft 23, the blade mounting shaft 25, the roller shaft 38 and the hanger mounting shaft 37 is also formed between the drive link 20 and the rotation lever 34.

A guide roller (guide portion) 40 is rotatably attached to the roller shaft 38. The guide roller 40 can come into contact with the cam 36 by moving the car door 5 in the direction of the front door of the car doorway 2. The guide roller 40 is connected to the cam 36 only when the car door 5 is within a predetermined movement range from the position where the car doorway 2 is closed to the position where the fixed blade 19 and the fixed engagement roller 29 start to be engaged. To touch.

When the guide roller 40 is away from the cam 36, the movable blade 21 has reached the gripping position due to its own weight. At this time, even if the car door 5 moves, the position of the movable blade 21 is maintained at the gripping position (FIG. 2).

When the guide roller 40 is in contact with the cam 36, when the car door 5 is moved in the door closing direction, the rotation lever 34 is rotated in the direction in which the movable blade 21 is displaced to the release position. When the door 5 is moved in the door opening direction, the turning lever 34 is turned in the direction in which the movable blade 21 is displaced to the gripping position.

When the rotation lever 34 is rotated in the direction in which the movable blade 21 is displaced to the release position, the guide roller 40 is guided upward by the cam 36. When the rotating lever 34 is rotated in the direction in which the movable blade 21 is displaced to the gripping position, the guide roller 40 is guided downward by the cam 36.

Next, the operation will be described. When both the car doorway 2 and the landing doorway are closed, the movable blade 21 is held at the gripping position with the guide roller 40 in contact with the cam 36. At this time, the fixed blade 19 and the movable blade 21 are disposed at positions away from the landing side engaging device 18 in the front-and-rear direction of the car entrance 2. Further, at this time, the landing door is locked by the locking device 31 (FIG. 1).

When the door 5 of the car is moved in the door opening direction by the driving force of the door driving device 8 during the door opening operation, the fixed blade 19 moves while pressing the movable engagement roller 30 after contacting the movable engagement roller 30. The engaging roller 30 is displaced from the forward movement position to the backward movement position. Thereby, the locking of the collar member 32 with respect to the locking member is released, and the locking of the landing door is released.

At this time, the guide roller 40 is guided downward while contacting the cam 36 as the car door 5 moves in the door opening direction. Thereby, the rotation lever 34 and the drive link 20 are rotated in the direction in which the connecting rod 35 is displaced upward, and the movable blade 21 is displaced from the release position to the gripping position. At this time, the turning lever 34 and the drive link 20 are turned in the same direction.

When the movable engagement roller 30 reaches the retracted position, the fixed blade 19 is engaged with the fixed engagement roller 29 and the movable blade 21 reaches the gripping position. As a result, the fixed engagement roller 29 and the movable engagement roller 30 are collectively held between the fixed blade 19 and the movable blade 21. At this time, the guide roller 40 is separated from the cam 36.

Thereafter, while the fixed engagement roller 29 and the movable engagement roller 30 are held between the fixed blade 19 and the movable blade 21, the door 5 of the car is moved in the door opening direction together with the landing door, and the door opening operation is performed. Is completed.

During the door closing operation, the car door 5 is moved in the door closing direction together with the landing door while the fixed engagement roller 29 and the movable engagement roller 30 are held between the fixed blade 19 and the movable blade 21. Thereafter, when the landing door reaches a position where the landing doorway is closed, the guide roller 40 comes into contact with the cam 36 and the fixed blade 19 is detached from the fixed engagement roller 29.

Thereafter, when the car door 5 is further moved in the door closing direction, the guide roller 40 is displaced upward by the guide of the cam 36 and the connecting rod 35 is displaced downward, and the driving lever 34 and the drive are driven. The link 20 is rotated. As a result, the movable blade 21 is displaced from the gripping position to the release position. At this time, the turning lever 34 and the drive link 20 are turned in the same direction.

Thereafter, the stationary blade 19 is separated from the movable engagement roller 30, and the car door 5 is further moved in the door closing direction, whereby the door closing operation is completed.

In such an elevator door device, the direction of rotation of the drive link 20 about the first panel mounting shaft 23 and the direction of rotation of the rotating lever 34 about the hanger mounting shaft 37 are the same. Since the drive link 20 and the rotation lever 34 are interlocked with each other so as to be in the direction, it is possible to prevent the inclination of the connecting rod 35 from changing greatly when the drive link 20 and the rotation lever 34 are rotated. it can. Therefore, even when the position of the car-side engagement device 17 with respect to the rotation lever 34 is shifted due to the adjustment of the position of the car-side engagement device 17 at the time of installation, the movable blade 21 with respect to the rotation amount of the rotation lever 34. It is possible to suppress a large change in the amount of displacement. Thereby, the operation | work which adjusts the position of the rotation lever 34 at the time of installation of the door apparatus of an elevator can be avoided, and the installation operation | work of an elevator door apparatus can be made easy.

Further, the distance between the link connecting shaft 26 and the lever connecting shaft 39 is the same as the distance between the first panel mounting shaft 23 and the hanger mounting shaft 37, and the link connecting shaft 26 and the first panel mounting shaft. 23 is the same as the distance between the lever connecting shaft 39 and the hanger mounting shaft 37, so that the connecting rod 35 can be inclined even if the drive link 20 and the rotating lever 34 are rotated. It can be kept constant at all times. Therefore, even if the position of the car-side engagement device 17 with respect to the rotation lever 34 is shifted, the displacement amount of the movable blade 21 relative to the rotation amount of the rotation lever 34 can be kept constant, and the movable blade 21 is displaced more accurately. Can be made.

Further, when the movable blade 21 is in the gripping position, the direction of the straight line connecting the first panel mounting shaft 23 and the blade mounting shaft 25 is the same as the moving direction of the car door 5, so the movable blade 21. Even when receiving a force in the door opening direction, the movable blade 21 can be prevented from being pushed back from the gripping position to the release position, and the movable blade 21 can be held more securely at the gripping position. be able to.

In the above example, the dimension between the ceiling of the car 1 and the upper edge of the car doorway 2 is increased, and the car-side engagement device 17 and the gripping drive device 33 are arranged apart from each other in the vertical direction. The present invention is applied to the elevator door device, but as shown in FIG. 3, the size between the ceiling of the car 1 and the upper edge of the car doorway 2 is reduced, and the car-side engaging device 17 The present invention may be applied to an elevator door device in which the grip driving device 33 partially overlaps in the vertical direction. In this case, the vertical position of the car-side engagement device 17 with respect to the gripping drive device 33 is adjusted by adjusting the length of the connecting rod 35. Further, the fixed blade 19 and the movable blade 21 are arranged so as to be shifted in the depth direction of the car 1 with respect to the gripping drive device 33.

Is provided with a recess 53 into which the guide roller 40 fits. The gripping biasing spring 51 biases the rotating lever 34 in a direction in which the guide roller 40 fits into the recessed portion 53.

Therefore, when the car door 5 is moved in the door closing direction, the guide roller 40 comes into contact with the cam 36, and then is displaced upward and then downward, and fits into the recess 53. Thus, when the car door 5 is moved in the door closing direction, the movable blade 21 is once displaced to a position farther from the fixed blade 19 than the release position, and is then displaced to the release position. Other configurations are the same as those in the first embodiment.

In such an elevator door device, the rotation lever 34 is biased by the gripping biasing spring 51 in the direction in which the movable blade 21 is displaced to the gripping position, and the car door 5 reaches a position where the car doorway 2 is closed. As a result, the recessed portion 53 into which the guide roller 40 is fitted is provided in the cam 36, so that the movable blade 21 can be more reliably held at the release position.

In the above example, the rotating lever 34 is biased by the gripping biasing spring 51, but the gripping biasing spring 51 may bias the drive link 20. In this case, the drive link 20 is biased in the direction in which the movable blade 21 is displaced to the gripping position.

Further, in each of the above embodiments, the displacement of the movable blade 21 is regulated by the stopper 28 that receives the drive link 20. However, the displacement of the movable blade 21 is regulated by the stopper that receives the rotation lever 34. You may do it. In this case, the stopper is fixed to the door hanger 7.

Moreover, in each said embodiment, although the guide roller 40 is provided in the rotation lever 34 as a guide part guided while contacting the cam 36 with the movement of the car door 5, it is limited to this. For example, a protrusion may be provided on the rotating lever 34 as a guide portion. In this case, the rotation lever 34 is rotated by being guided while the protrusion is in contact with the cam 35.

2 car doorway, 5 car doors, 17 car side engaging device, 18 landing side engaging device, 19 fixed blade, 20 drive link (rotating link), 21 movable blade, 25 blade mounting shaft, 26 link connecting shaft, 33 Gripping drive unit, 34 Rotating lever, 35 Connecting rod (connecting member), 36 Cam, 37 Hanger mounting shaft (lever support shaft), 39 Lever connecting shaft, 40 Guide roller (guide unit), 51 Energizing for gripping Spring (biasing body), 53 depressions.
