Abstract

PROBLEM TO BE SOLVED: To easily open doors by constituting an opening device for landing doors even if opening work can be carried out from only the lower part of the door by an operator. SOLUTION: Since an opening device for landing doors is constituted by attaching a movable body 10 positioned in the closing direction side of the landing door from the position of door hangers 3 in full-closing of the landing door and capable of being moved along a door rail 1 so that an operating body 12 for moving the movable body 10 toward the door hanger 3 may be operated on the lower part of a door panel 4, the movable body 10 presses the door hanger 3 in the door opening direction and can open the door by operating the operating body 12 even if opening of the door can be performed from only the lower part of the door panel 4.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an elevator landing door opening device.

[0002]

2. Description of the Related Art The structure of a conventional elevator landing door will be described with reference to FIG.

FIG. 3 is a front view showing the structure of a conventional elevator landing door.

[0004] As shown in the figure, the landing door of the elevator is
A door roller 2a and an eccentric roller 2b that rotatably abut against a door rail 1 extending in the door opening and closing direction, respectively.
A door hanger 3 to which these guide rollers are attached, and a door panel 4 whose upper end is attached to the door hanger 3 and whose lower end 4a is engaged with a sill 5 laid on the landing floor. It is comprised including.

The landing door is connected to door driving ropes 7 wound endlessly between two pulleys 6 installed on the upper part of the door rail 1 at connecting portions 8 and 9, respectively. When one of the doors moves, the other door moves in a direction opposite to the moving direction of the one door.

Next, a conventional method of manually opening the door will be described.

As a method, a worker inserts his hand between the two door panels 4 and moves the door in the left direction in the case of the left door and in the right direction in the case of the right door in the drawing. Was open.

[0008]

However, there were cases where the door could not be opened by the conventional opening method. That is,
Inspection work is performed at the bottom of the hoistway, and the door is manually opened when, for example, exiting from the hoistway side to the landing side. Will be moved,
The hand can be reached only near the lower end of the door panel 4.

However, for example, when a leftward force is applied to the lower end of the door panel 4 of the left door, the upper end of the door panel 4 tends to tilt to the right, and the door hanger 3 mounted on the upper part of the door panel 4 also has this force. Power is transmitted. And
When the force is transmitted to the door hanger 3 in this manner, the door rail 1 is sandwiched between the right door roller 2a and the left eccentric roller 2b, and there is a problem that the door does not move and cannot be opened.

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above problems, and has as its object to open an elevator landing door which enables the door to be easily opened even when an operator can only open the door from below the door. In providing the device.

[0011]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a door hanger having a guide roller rotatably abutting on a door rail and moving along the door rail in response to the rotation. In the elevator landing door opening device having a door panel whose upper end is connected to the door hanger, the door rail located on the closing direction side of the landing door from the position of the door hanger when the landing door is fully closed, A movable body movably attached along the door rail, one end of which is attached to the movable body and the other end of the movable body is suspended below the door panel, and the movable body is directed toward the door hanger in response to operation. And an operating body for moving the object.

According to the present invention, a movable member movable along the door rail is attached to a door rail positioned on the side closer to the landing door than the position of the door hanger when the landing door is fully closed. Since the landing door opening device is configured so that the operating body moved toward the door hanger can be operated below the door panel, even when the door can be opened only from below the door panel, the movable body can be operated by operating the operating body. The door can be opened by pushing the hanger in the door opening direction.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of a landing door showing an installation state of an elevator landing door opening apparatus according to an embodiment of the present invention, and FIG. 2 is an enlarged view of a main part of FIG.

First, the configuration of the elevator landing door opening device of the present invention will be described.

The elevator landing door opening apparatus of the present invention comprises a movable body 10 and an operating body 12.

In FIG. 1, a movable body 10 includes a roller 10b rotatably abutting on the upper and lower surfaces of the door rail 1, a base 10a connecting the rollers 10b, and a base 10a.
And an elastic body 10c made of urethane rubber or the like attached to the front end of the door hanger 3 side.
When the door shown in FIG. 3 is fully closed, the door closing direction is shifted from the position of the door hanger 3, that is, two door hangers 3 in the drawing.
The door rail 1 is positioned so as to be engaged with the door rail 1.

The operating body 12 composed of a rope or the like
One end is attached to the movable body 10, and the other end is suspended below the door panel 4 via the guide pulley 11.

Next, a door opening method using the elevator landing door opening apparatus of the present invention will be described with reference to FIG.

After the inspection of the bottom of the hoistway, etc., the worker 13 who has climbed to the vicinity of the landing grasps the operating body 12 and lowers it downward.

In such a case, the movable body 10 is pulled toward the door hanger 3 by the operating body 12 and
At 0c, the door hanger 3 is pushed in the door opening direction, that is, leftward in the figure, so that the door is opened smoothly without pinching the door rail by the guide roller as described above.

Accordingly, in this state, the worker 13 can go to the landing while holding the door open state by holding the lower end of the door panel 4.

As described above, according to the present invention, the door can be easily opened by operating the operating body 12 even when the operator 13 can perform the door opening operation only from below the door panel 4.

The movable body 10 is attached to the door rail 1 which is not in contact with the door hanger 3 when the door is normally opened and closed, that is, the door rail 1 which is located in the door closing direction from the position of the door hanger 3 when the door is fully closed. Does not hinder the opening and closing of the door.

Further, since the elastic body 10c is provided at the portion of the movable body 10 which comes into contact with the door hanger 3, the movable body 10
The door hanger 3 is not damaged when the door hanger 3 is pressed by the door hanger.

Further, according to the present embodiment, a door that opens in the left and right direction from the center has been described as an example. A similar effect can be obtained by attaching the movable body 10 to the door rail 1 located in the door closing direction and hanging the operating body 12 below the door panel 4.

[0027]

According to the present invention, since the landing door opening device is constructed as described above, the door can be easily opened even when the worker can perform the opening work only from below the door.
