Description

[Detailed explanation of the idea] This invention relates to an elevator door device.

Generally, elevator landing doors are provided with a locking piece that engages with a fixed piece fixed to the landing when the door is closed, and also engages with a locking piece provided on this when facing the car door. ,
An engagement device is provided for unlocking the lock piece and driving it together with the car door.

With these devices, when the landing door is fully closed, it is locked by the engagement of the fixed piece and the locking piece, and when the elevator car arrives at the landing, the engagement plate provided on the car door and the landing door are locked. When the car door starts to open, the lock piece is unlocked, and the landing door and the car door are opened and closed together via the engagement device. There is.

However, this type of door device has a problem that the number of parts (fixing piece, locking piece, and engaging device) is large, which increases manufacturing costs.Also, the locking device is separate from the locking piece, so it cannot be attached to the landing door. Because of this, fine adjustment of the mounting position is required, which has the disadvantage of complicating installation and maintenance work.

This invention aims to solve the above-mentioned drawbacks and to provide an elevator door device that can be manufactured at low cost and that can be easily installed and maintained.

An embodiment of this invention will be described below with reference to FIGS. 1 and 2.

In the figure, 1 is a banger case fixed to the hall wall 2, 3
is a hanging wheel 5 on the rail 4 fixed to the banger case 1.
8 is a bunker case cover, and the upper part is fixed to the banger case 1 and is arranged to cover the front surface of the banger case 1. ing.

9 has an L-shape, and the L-shaped bent part is the banger plate 3.
The operating body is pivotally mounted on the horizontal side and engages with a fixed piece 11 fixed to the lower part of the mounting bracket 10 fixed to the banger case 1 on the left side in Fig. 2, when the door 7 of the landing is fully closed. A locking hook 9a is provided.

9b has a part of the horizontal side bent at right angles,
A weight 12 that biases the actuating body 9 counterclockwise in FIG. 2, and a protrusion 15 that attaches a short-circuit contact 14 that short-circuits the contact contact 13 at the time of locking and confirms that the locking is completed electrically. A screw 9b is screwed into the pin 9b, and its tip contacts the backing plate 16 fixed to the banger plate 3 to prevent counterclockwise rotation of the actuating body 9 at a predetermined position.
This collar bolt is used to maintain the engagement dimension between the hook 9a and the fixing piece 11.

Reference numeral 9C is one side extending upward from the actuating body 9, and is bent into a two-shape shape at the unlocking side to which the shaft 18 that pivotally supports the unlocking roller 17 is fixed, as shown in FIG.

9d' is a bent part of the actuating body 9, and a cylindrical seat 9e is welded to the part where the bearing 19 is housed.The actuating body 9 fits into this bearing 19, and one side is attached to the banger plate 3, forming a Z-shape. It is rotated by a shaft 21 fixed to the other side of the molded mounting plate 20 for unlocking and locking operations.

Further, a drive roller 22 is pivotally attached to the other end of the shaft 21.

The driving roller 22 and the unlocking roller 17 are formed to have substantially the same outer diameter.

Reference numerals 23 and 24 designate a pair of engagement plates that are respectively provided on the car door (not shown) so that when the car door moves, the facing distance changes by a cam or the like (not shown).

That is, when the car door faces the landing door 7, the unlocking roller 17 and the driving roller 22 are arranged between the engagement plates 23 and 24, and when the car door starts to open, the engagement plate 23 moves to the unlocking roller. 17, and in FIG. 1, the unlocking roller 1
7 moves to the right, and as a result, the actuating body 9 rotates clockwise about the shaft 21, and the hook 9a of the actuating body 9 comes off from the fixed piece 11, completing unlocking.

Next, the engagement plate 23 moves further to the right, and the drive roller 22
Since the car door has already been unlocked when it starts to touch the car door, that is, the landing door 7 is moved at the same time as the engagement plate 23 is moved.
begins to open when the drive roller 22 is pushed.

As the car door opens, the distance between the engaging plates 23 and 24 is narrowed by a cam (not shown), etc., and the driving roller 22 and the unlocking roller 17 are gripped without any gaps, so the landing door 7 is quiet. driven by

In this way, the driving roller 22 is provided at the pivot point of the actuating body 9,
Moreover, an unlocking roller 17 is provided above this, that is, on the unlocking side 9C.
Since the actuating body 9 and the engaging device are integrated with each other, it can be made compact and can be housed in the banger case 1, which serves as a reference for the installation position when installing the elevator.

This eliminates the need for unlocking and fine adjustment of the position of the locking device consisting of drive rollers 17, 22, etc., and can save time and effort during installation.

Further, since the unlocking roller 17 is arranged in front of the banger case 1, the banger case cover 8 can be provided on the front of the banger case 1 even though the main part of the engagement device is housed inside the banger case 1. .

Further, since the actuating body 9 moves downward to lock the door, high reliability of the locking operation can be obtained.

As explained above, this invention has an unlocking roller in the operating body.
Since the drive roller is attached to form an integrated locking device, the number of parts can be reduced and manufacturing can be done at low cost.

In addition, it can be made smaller and narrower, and can be housed in a banger case that serves as a reference for the installation position, eliminating the need for fine adjustment of the installation position, making it easy to install and highly reliable.
This realizes a quiet elevator door system.
