Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner for an elevator, and more particularly to an air conditioner for an elevator that air-conditions a car by means of an air conditioner main body arranged on the car.

[0002]

2. Description of the Related Art Generally, an air conditioner for an elevator has an air conditioner main body for generating cold air and warm air arranged on a car and guides the air generated by the air conditioner main body into a car through a guide means. To do. The air conditioner body is fixed on the car by mounting means.

However, since the air conditioner main body fixed on the car by the mounting means occupies a space on the car, a work space for maintenance work on the car and passengers in the car in an emergency It was difficult to secure a space for the rescue exit installed on the ceiling of the car to rescue the car. This problem was particularly noticeable when the air conditioner body was installed on a car with a small external dimension.

For this reason, as described in Japanese Patent Laid-Open No. 13590/1990, an air conditioner main body is installed on a ceiling surface of a car so that it can be moved from a predetermined position to another position via a guide rail. Is proposed.

[0005]

By the way, in the above-mentioned conventional air conditioner for an elevator, the air conditioner main body is installed on the car, and in order to secure a working space for maintenance work and a use space for the rescue exit, Elevators with small car dimensions, where at least a part of the machine body has to be moved from a predetermined position to outside the car dimensions, are not taken into account. Even if the air conditioner main body can be moved from a predetermined position to outside the outside dimensions of the car, the vibration of the car will cause the air conditioner main body to move and stick out of the outside dimensions of the car, or the outside dimensions of the car. No consideration was given to the problem of forgetting to return the air conditioner main body moved to the outside of the vehicle to the predetermined position and running the car, and causing the air conditioner main body to collide with and damage the equipment.

The present invention has been made in view of the actual situation in the prior art as described above. A first object of the present invention is to make it possible to secure a necessary space on a car having a small external dimension, and to prevent vibration due to vibration or the like. An object of the present invention is to provide an elevator air conditioner capable of preventing the air conditioner main body from moving.

A second object is to provide an elevator air conditioner capable of positioning the air conditioner main body at a predetermined position when the car is traveling.

[0008]

In order to achieve the first object, the invention according to claim 1 of the present invention is an air conditioner main body which is arranged on a car and generates cold air and warm air, and this air conditioner. In an air conditioner for an elevator comprising guide means for guiding air generated in a main body into the car, at least a part of the air conditioner main body on the car from a predetermined position to outside of the car external dimensions. Is provided so as to rotatably support the air conditioner and a fixing means that can fix the air conditioner main body at the predetermined position.

According to the first aspect of the present invention, when the rescue exit provided on the car is used or when maintenance work is performed on the car, the air conditioner main body is rotated through the rotating means. Rotate from a predetermined position so that at least a part of it is located outside the outer dimensions of the car. By rotating the air conditioner main body through the rotating means in this manner, it is possible to secure a necessary space on the car having a small outer dimension. In addition, by fixing the air conditioner main body to a predetermined position by the fixing means during normal times including the operation of the car, it is possible to prevent the air conditioner main body from moving due to vibration or the like.

Further, in order to achieve the second object, the invention according to claim 4 of the present invention is configured to include a returning means for returning the rotated air conditioner main body to the predetermined position.

According to the fourth aspect of the present invention, the air conditioner main body is rotated through the rotating means in order to use the rescue exit provided on the car or to perform maintenance work on the car. When the air conditioner main body is rotated so that at least a part thereof is located outside the outside dimension of the car, the air conditioner main body is returned to the predetermined position inside the outside dimension of the car by the returning means. As a result, the air conditioner body can be reliably positioned at the predetermined position when the car is traveling.
