Abstract

(57) [Abstract] [Purpose] To provide an elevator door device capable of preventing deformation in the door entrance / exit direction due to external force, preventing damage to door attachment parts, improving maintenance, and maintaining a product life for a long period of time. [Structure] The door hanger 5 is provided with a stopper 20 for receiving a reaction force against the external force acting on the door 6 only when an external force acts on the door 6 of the elevator, and the hanger case 1 receives the reaction force. [Effect] Since the stopper works only when an external force acts on the door, the deformation of the door is regulated without generating an abnormal sound such as a contact sound when the door is normally opened and closed.
The device attached to the door can be prevented from coming into contact with other devices.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator door device, and more particularly to an elevator door device capable of maintaining a product life for a long period of time.

[0002]

2. Description of the Related Art A conventional technique is disclosed in, for example, Japanese Utility Model Publication No. 61-14.
As shown in FIG. 1 of Japanese Patent No. 2772, the structure is such that it always opens and closes while receiving a reaction force against the external force acting on the door.

[0003]

However, in the above-mentioned prior art, the door is bent when an external force is applied, an abnormal sound is generated when the door is opened or closed, and the parts are worn, so that the life of the parts is shortened. , It was necessary to replace the parts regularly.

An object of the present invention is to provide an elevator door device which can prevent deformation of the door in the direction of the entrance and exit of the door due to external force, prevent damage to door attachment parts, improve maintenance, and maintain a product life for a long period of time. is there.

[0005]

In order to solve the above problems, the present invention provides a door rail provided at an upper part of an entrance / exit of an elevator, a door hanger for rollingly guiding an upper part of the door rail by a hanger roller, and the door hanger. In an elevator door device including a door that is suspended and guided at a lower end to engage with a sill, and a hanger case that attaches the door rail, the door hanger includes a stopper that receives deformation of the door in the entrance / exit direction in the hanger case. It is characterized by being provided. Further, a mounting part mounted on the door hanger is used as a stopper, and a gap between the mounting part and the hanger case is set to about 1 mm to 3 mm.

[0006]

According to the above construction, since the door hanger is provided with the stopper for receiving the reaction force when the door receives an external force in the direction of the doorway, the parts attached to the door by receiving the reaction force by the hanger case. However, it is possible to prevent problems such as abnormal protrusions due to deformation of the door.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Some embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an enlarged view of a portion A of FIG. 2 showing an upper part of a car side door of an elevator and side surfaces of a hall side door and a car side door, and FIG. 3 is a front view of the car door as seen from the hall side.

As shown in these figures, a door rail 3 is attached to a hanger case 1 by means of a jispi 2 and a car hanger 5 is equipped with a hanger roller 4 for rolling and guiding the upper side of the door rail 3. 6
Is suspended. At the bottom of the car door 6, there is a door guide shoe 7, which guides opening and closing along the groove of the sill 8.
A safety shoe 9, an engagement device 10, a door machine link 11 and the like are attached to the car door 6. Similarly, the hall side has a hanger case 12, a door rail 13, a hanger roller 14, a door hanger 15, a hall side door 16,
The door guide shoe 17 and the sill 18 are provided, and the door hanger 15 includes an engagement roller 19 that opens and closes the hall side door 16 in conjunction with the engagement device 10 attached to the car door 6.

In the elevator door device constructed as described above, the engaging device 10 and the engaging roller 19 are separated from each other on the car door 6 when, for example, the vehicle is bumped against the safety shoe when getting into the elevator. When an external force in the door entrance / exit direction acts, the car door 6 is conventionally deformed by this external force and the engagement device 10 and the engagement roller 1
It becomes impossible to secure the engagement dimension with 9, and the engagement is dislocated, resulting in a failure. However, by providing the stopper 20 on the door hanger 5 and providing a gap of about 1 mm to 3 mm between the stopper 20 and the hanger case 1, the stopper 20 is provided to the hanger case 1 by an amount that the car door 6 is deformed by an external force. It can be regulated by abutting. Therefore, it is possible to easily increase the apparent rigidity without changing the rigidity of the car door 6.

Further, as shown in FIG. 4, the door hanger 5
By disposing the stoppers 20 and 21 above and below the door rail 3, the deformation of the car door 6 is restricted not only from the hole side but also from the inside of the car so that the direction of the external force acting on the car door 6 can be restricted. You can

FIG. 5 shows another embodiment of the present invention. Instead of providing a stopper, the hanger roller 4 and the steady rest roller 22 attached to the hanger 5,
By disposing the gap with the hanger case 1 to be approximately 1 mm to 3 mm, the deformation of the car door can be restricted by the hanger roller 4 or the steady rest roller 22 coming into contact with the hanger case 1.

Further, as shown in FIG. 6, similarly to FIG. 1, a stopper 20 attached to the door hanger 5 is provided below the door rail 3, and the tip of the stopper 20 is opened in the hanger case 1 along the longitudinal direction. The guide 2 at the position where a gap of approximately 1 mm to 3 mm is provided so as to sandwich the hanger case 1 in front of and behind the plate thickness of the hanger case 1.
By arranging 0a and 20b, the deformation of the car door can be restricted.

Further, although bolts are used as the stoppers described above, any stoppers that restrict deformation of the car door in the direction of the entrance and exit may be used, and other parts may be used as in the embodiment shown in FIG. May be. In addition, a rotating body such as a roller or a ball, or a sliding member such as a synthetic resin may be provided at a portion where the above-mentioned stopper or other component comes into contact with the hanger case. By configuring the steady rest roller 22 shown in FIG. 5 or FIG. 3 with a freely rotating ball and setting the clearance between the hanger case and the hanger case to 1 mm to 3 mm,
Contact with the hanger rail due to runout in the door opening and closing direction,
The contact with the hanger case due to the deformation in the door entrance / exit direction can be made smoother.

As described above, according to these embodiments, when an external force perpendicular to the door surface acts on the door,
By installing a stopper that suppresses the deformation of the door on the door hanger at the top of the door, the rigidity of the door can be maintained as it is and the parts such as the engagement device that are attached to the door interfere with the parts on the hole side. There can be no. Further, by providing the stopper on the upper side, the lower side, or both sides of the center of the door rail, the direction in which the deformation of the door is restricted can be limited with respect to the direction of the external force acting on the door. Although the embodiment has been described with respect to the door on the car side, it goes without saying that the door on the hall side has the same effect.

[0015]

As described above, according to the present invention, in an elevator door device, deformation of the door in the direction of the doorway due to external force is prevented, damage to door attachment parts is prevented, maintenance is improved, and product life is extended for a long time. Can be maintained.
