Problems solved by technology

[0009] However, there may be cases where the normal power supply fails due to an elevator failure
In such a case, the fans 2 and 3 for air pressure control cannot be driven and controlled. In addition, since the elevator car itself is a highly airtight structure, once the car cannot be ventilated, the oxygen concentration in the car will decrease. Falling will not only make passengers feel uncomfortable, but also may lose safety

Embodiment Construction

[0021] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0022] (first implementation)

[0023] figure 1 It is a perspective view of a car of one embodiment of an elevator equipped with a ventilator according to the present invention.

[0024] 1 in this figure is a car 1 for carrying passengers up and down. The car 1 is composed of the following parts, that is, the car floor 4; the side panel 5 vertically arranged on the car floor 4; Car roof 6; the entrance column 7 that is vertically arranged on both sides of the car front car door opening; the car door panel 8 that can slide at the opening part of the car door and the closed car door panel 8 top and the car roof The baffle plate 9 etc. of gap between 6. In order to realize airtight control inside the car room, the car 1 is assembled to maintain a very high airtightness.

[0025] As mentioned above, the structure of the upper part of the car 1 is: the above-mentioned a...

Abstract

The objective of the present invention is to provide an elevator capable of maintaining airtightness and controlling an atmospheric pressure inside a car by using pressurizing and depressurizing means (2, 3). In the car (1) is provided with ventilating means (10) for natural or forcible ventilation. An example of the ventilating means (10) is comprised of ventilating windows (11) formed in a ceiling of the car, ventilating window plates (12c) for closing the ventilating windows, lock means (13) normally locking the ventilating window plates so as to close airtight the ventilating windows and, when receiving a normal power failure signal, releasing the lock, and window open / close means (12) for opening the ventilating window plates, which when the lock is released, by the weights of weights (12f) suspended from the other end parts of wire ropes (12e) fixed to the ventilating window plates, whereby the safety of passengers can be assured by allowing the inside of the car to be ventilated when a power fails due to a trouble with the elevator.

Description

technical field [0001] The present invention relates to an elevator for ventilating the inside of the car when the normal power supply is cut off accompanying the elevator failure. Background technique [0002] With the increase in the height of buildings in recent years, ride comfort and high-speed elevators are also required. When the height of the building exceeds 300 meters, the passengers of the elevator may feel uncomfortable due to the change of air pressure during the lift. In addition, the very high speed of lifting and lowering may also have a physiological impact on the auditory function of passengers. [0003] Then, from the viewpoint of reducing the above-mentioned influence as much as possible, an air pressure control device that changes the air pressure inside the car according to the air pressure outside the car has been proposed. [0004] The elevator is as Figure 8 The structure shown, that is, the upper part of the car 1 is provided with an air supply f...
