Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevator door device.

First, a conventional door device will be explained with reference to FIGS. 1 to 4.

In the figure, 1 is an elevator hoistway, 2 is a landing consisting of a landing door 3, a landing sill 4, etc. installed therein, 5 is a car placed across a gap 6 from the landing 2, and 7 is a car. The car door 8 is a landing engagement device disposed above the gap 6 protruding from the landing door 3, and is mainly composed of a fixed engager 8a and a movable engager 8b arranged apart from this. has been done.

9 is a space formed between the fixed and movable engagers 8a and 8b; 10 is an engagement device whose tip protruding from the car door 7 extends into the space 9; the fixed plate 10a and the movable plate; 10
When the car door 7 is in the fully closed position, it is in a narrow state and the tip is fixed, and the movable engager 8a,
It is configured so as to face 8b across the playboy,
In addition, the movable engager 8a is widened and fixed as the car door T is opened.

8b are sandwiched and engaged with each other.

That is, as is well known, the car 5 normally moves up and down along a predetermined path.

Since the car door 7 is fully closed at this time, when the car 7 passes through the landing 2, the car engaging device 10 passes through the empty space 9 without contacting the landing engaging device 8.

However, if an earthquake occurs and a vibration occurs in a direction perpendicular to the up-and-down direction, that is, a lateral shake occurs, the car engaging device 10 is displaced left and right or up and down in FIG. 1.

Therefore, the car engagement device 10 and the landing engagement device 8, the car engagement device 10 and the landing 2, or the landing engagement device 8 and the heel 5 collide with each other.

This collision causes damage to the car and landing engagement devices 10 and 8, and even if there is no damage to the main parts of the elevator due to the earthquake, the car and landing doors 7 and 3 cannot be opened, and the car and landing engagement devices 10 and 8 become unable to open.
There is an inconvenience that passengers are trapped inside.

This invention solves the above-mentioned drawbacks, and prevents the car and the landing door engagement device from colliding and being damaged when the car is moved up and down an abnormal path due to an earthquake or the like. The present invention aims to provide an elevator door device.

An embodiment of the present invention will be described below with reference to FIGS. 5 to 9.

In the figure, the same reference numerals as those in FIGS. 1 to 4 indicate corresponding parts, and 11 is an upper guide body attached to the landing door 3 and arranged above the landing engagement device 8, and is formed by a bent plate. A slope 11a1 whose lower part is inclined toward the center of the space 9 and covers the upper part of the fixed engager 8a, and a slope 11b formed in the same way as the slope 11a1 which covers the upper part of the movable engager 8b,
Slope 11c that slopes from the protruding side toward the landing door 3
is the setting.

Reference numeral 12 denotes a lower guide body which is attached to the door 3 of the landing and is arranged in a symmetrical position and shaped symmetrically to the upper guide body 11 via the landing engagement device 8, and the slopes 11a, ll of the upper guide body 11
Slopes 12a, 12b, 1 corresponding to b, 11c, respectively
2c is provided.

Reference numeral 13 denotes car guide bodies disposed at the upper and lower ends of the car engagement device 10, and a portion thereof is attached to the fixed plate 10a to form a substantially pyramidal shape. The slope 13b is provided with two slopes 13a that protrude and cover the end face of the car engagement device 10 in a narrow state, and slopes from the protruding edge of the car engagement device 10 toward the T surface of the car door.
is the provision.

Now, suppose that a car 5 approaches the landing 2 from above when a lateral shake occurs, and the direction of the lateral shake is in the left-right direction in FIG.
3 contacts either the slope 11a or llb of the upper guide body 11.

The car engaging device 10 is guided toward the space 9A by this slope.

Furthermore, if the horizontal shaking of the car 5 is in the vertical direction in FIG.
contact c.

The heel 5 is guided away from the landing engaging device 8 by the slope 11c.

Furthermore, when the car 5 passes downward through the landing 2 and is swaying horizontally in the vertical direction in FIG. 1, the car engagement device 10 may come into contact with the edge of the sill 4 of the landing.

At this time, the car engaging device 10 is guided in a direction away from the landing 2 by the slope 13b of the car guide body 13 disposed at the lower end of the car engaging device 10.

In addition, when a horizontal shake occurs and the car 5 approaches the landing 2 from below, the car is engaged by the lower guide body 12. Device 10 is guided in the direction of space 9 .

In this way, it is possible to prevent the car engagement device 10 and the landing engagement device 8 from being damaged due to collision with each other when the car 5 in which the car 5 has swayed passes through the landing 2.

Therefore, it is possible to prevent passengers from being trapped in the car 5 due to damage to the car or the landing engagement devices 10, 8.

In addition, as an incidental effect, the upper and lower guide bodies 1
The slopes 11a to 12, 11a to 12c, 12a to 12c provide the effect of preventing an accident in which the moving cable of the elevator (not shown) sways and gets entangled with the landing engaging device 8.

As explained above, the present invention provides guide bodies above and below the engagement device attached to the landing door, respectively, and allows the door engagement device attached to the car door to be guided by the guide body in a predetermined manner. It is designed to guide the object along the relative movement path of the object.

This makes it possible to prevent damage to the engagement device due to collision when the car that is shaking laterally passes through the landing.
This prevents accidents in which passengers are trapped due to damage to the securing device.
