Description

The present invention relates to an elevator provided with an emergency ventilation port in a car.

In recent years, various high-speed elevators that raise and lower the car at a speed of several hundred meters per minute have been proposed with the increase in the height of buildings. In this type of elevator, the air pressure inside the car is adjusted by a pressure adjusting device such as a blower that sucks and exhausts the inside of the car so that the passengers do not feel uncomfortable due to a sudden change in air pressure during ascending and descending.

In order to control the air pressure in the car to the optimum state, it is necessary to use a car having a highly airtight structure. On the other hand, if the airtightness is improved, there is a risk that the inside of the car will be oxygen deficient when the power supply is stopped due to a power failure or the like and the operation of the atmospheric pressure adjusting device is stopped. Therefore, in elevators, it is stipulated as a standard to provide an emergency ventilation port (hereinafter, simply referred to as "ventilation port") in the car. This ventilation port is normally closed by an opening / closing member such as a lid. Then, when the power supply to the elevator is stopped due to a power failure or the like, the opening / closing member is controlled to be opened.

For example, Patent Document 1 discloses a configuration in which a ventilation port is provided in a vertical portion of a base member having a substantially U-shaped cross section and opening outward from the peripheral surface, in which a side panel of a car is fixed to a platform.

By the way, this kind of high-speed elevator receives air resistance during traveling and generates noise and vibration such as wind noise, which may make elevator passengers feel uncomfortable. Therefore, an air conditioning cover as in Patent Document 2 is provided around the elevator car to regulate the wind during traveling.
