Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator car ceiling structure, and more particularly to an elevator car ceiling structure having an air conditioner.

[0002]

2. Description of the Related Art Generally, in an elevator having an air conditioner, an intake port and an exhaust port must be formed in a ceiling of a car for air circulation. However, in the elevator of a small car, the ceiling of the car incorporates emergency rescue doors, ceiling lighting fixtures, and ceiling reinforcement members that must be installed by law.
It is necessary to devise a ceiling structure for the car.

Therefore, in the elevator described in Japanese Utility Model Laid-Open No. 53-166265, an air conditioner 4 is arranged above the ceiling 2 of the car 1 as shown in FIG. Is connected through an intake port 7 formed in the upper part of the ceiling, and the end of the exhaust duct 6 is connected to an exhaust port 8 formed in the ceiling 2 to form an intake duct 5 at a position corresponding to the door 10 of the ceiling lighting fixture 9. The emergency rescue door 3 is formed. In other words, by forming the emergency rescue door 3 in the intake duct 5, space is saved by sharing parts.

[0004]

However, in the conventional elevator car ceiling structure of the elevator, since the emergency rescue door 3 is formed in the intake duct 5 of the air conditioner 4 as described above, the air conditioner 4 is provided above the car ceiling 2. Standardization with those that do not have will be impaired. That is, in a general elevator car ceiling structure that does not have an air conditioner, an emergency rescue door 3 is formed on the ceiling 2 located above the ceiling lighting fixture 9, as shown in FIG. The blower 11 is connected to. In this way, in a general elevator car ceiling structure that does not have an air conditioner, the emergency rescue door 3 is formed on the ceiling 2, whereas in an elevator car ceiling structure that has an air conditioner 4, the ceiling Since the intake duct 5 is connected to 2 and the emergency rescue door 3 is formed in the intake duct 5, the standardization of the ceiling 2 is impaired.

An object of the present invention is to provide an elevator car ceiling structure which can be standardized in many ways regardless of the presence / absence of an air conditioner.

[0006]

In order to achieve the above object, the present invention provides an emergency rescue door on the ceiling of a car of an elevator, and an intake port and an exhaust port of an air conditioner installed on the upper part of the car. In the elevator car ceiling structure comprising: an emergency rescue door, at least one of an intake port and an exhaust port of the cooling and heating device is formed in the emergency rescue door, and at least one of an intake duct and an exhaust duct deformable therein. It is characterized by connecting one or the other.

[0007]

In the elevator car ceiling structure according to the present invention, at least one of the intake port and the exhaust port of the cooling and heating device is formed in the emergency rescue door as described above. Also, since the rest of the configuration is the same except that it is an emergency rescue door that does not form an exhaust port, it is possible to standardize the ceiling structure.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view in vertical section showing a car ceiling structure of an elevator according to an embodiment of the present invention. A ceiling 2 is formed on an upper part of the car 1 through a ceiling lighting device 9, and a cooling / heating device 4 is arranged on an upper part of the ceiling 2. An intake duct 5 and an exhaust duct 6 are once connected to the air conditioning unit 4, and the other end of the intake duct 5 is connected to an emergency rescue door 3 that is openably and closably provided on the ceiling 2 above the ceiling lighting fixture 9. At the same time, the vicinity of the connection with the emergency rescue door 3 is formed of a deformable member such as a flexible member or a stretchable member. An intake port 7 is formed in the emergency rescue door 3 at the connecting portion with the intake duct 5. Exhaust duct 6
The other end of is connected to the ceiling 2 so as to have a communication relationship with the exhaust port 8. A door 10 is configured to be opened and closed at a lower portion of the ceiling lighting device 9 corresponding to the emergency rescue door 3.

In this way, the cooling / heating device 4 is provided in the car 1 ... Ceiling lighting equipment 9 ... Intake port 7 ... Intake duct 5
...... Exhaust duct 6 ...... Exhaust port 8 ...... Forms an air circulation path inside the car 1. Also, in an emergency, the door 10 can be opened and the emergency rescue door 3 can be pushed upward to open it, and can exit outside the car. At this time, since the intake duct 5 is deformable, it does not prevent the emergency rescue door 3 from opening.

Further, the elevator car ceiling structure which does not have the cooling and heating device 4 above the ceiling 2 is as shown in FIG. 2 as described above, but as can be seen by comparison with FIG. It suffices to make the ceiling part of the same structure the same, replace it with the emergency rescue door 3 of the same shape without the intake port 7, and connect the blower 11 to the exhaust port 8. Therefore, when the elevator car ceiling structure without the cooling / heating device 4 is standardized, when the cooling / heating device 4 is provided, the emergency rescue door 3 of the same shape having the intake port 7 is replaced, and the intake duct 5 and the exhaust duct 6 are replaced. It suffices to add the cooling and heating device 4 having

Although the intake port 7 is formed in the emergency rescue door 3 and the intake duct 5 is connected to the intake port 7 in the above embodiment, the exhaust duct 6 is connected and the intake duct 5 is connected to the exhaust port 8. The same effect can be obtained by connecting them. Further, both the intake port 7 and the exhaust port 8 may be formed in the emergency rescue door 3, and eventually, the intake port 7 and the exhaust port 8 are formed in the emergency rescue door 3.
It is sufficient to form at least one of the above. Further, in the above-described embodiment, the description is given as the double ceiling structure in which the ceiling lighting device 9 is incorporated in the lower portion of the ceiling 2 together with the shield plate.
The same effect can be obtained with a single-ceiling structure in which the ceiling lighting fixture 9 is directly provided below the door and the door 10 is unnecessary.

[0012]

As described above, according to the present invention, at least one of the intake port and the exhaust port of the cooling and heating apparatus is formed in the emergency rescue door, and at least one of the intake duct and the exhaust duct which can be deformed therein. Since one of them is connected, it is possible to easily attach the cooling / heating device by standardizing the elevator without the cooling / heating device.
