Embodiment Construction

[0026] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

[0027] Referring to Fig. 1, Fig. 1 shows the elevator car of the present invention, wherein the elevator car 1 is fixed on the frame 1a, and the frame 1a is provided with guide devices 2 at its four corners. The guiding device 2 is connected with a guide rail (not shown) arranged on the lifting shaft to guide the elevator car to move vertically along the guide rail not shown in the figure. The exit structure 3 is embedded in one side wall 4 of the elevator car 1 so that passengers can evacuate from the elevator car 1 when the elevator car is out of service due to a power outage or the like. The elevator car 1 is provided with an elevator door 1b for hermetically closing the exit of the elevator car 1 .

[0028] The elevator car 1 is formed by assembling a plurality of walls. The walls include side walls 4 (vertical walls), a top wall 4c (ceiling of the...

Abstract

An exit (5) formed in an elevator car (1) is closed by doors (8) of multi-construction including an inner door (6) and an outer door (7). Air is able to flow between a space between the inner door (6) and the outer door (7) and the space in the elevator car (1). The elevator car (1) can be sealed in an airtight state and can be isolated from external noise. Deformation of the decorative inner surface of the inner door (6) by pressure difference between the interior and the exterior of the elevator car (1) can be prevented.

Description

technical field [0001] The present invention relates to an outlet structure arranged in an elevator car, which is provided with a pressure control system for controlling the pressure in the car, or relates to an outlet structure arranged in an airtight elevator car, the elevator car Sealed to ensure a quiet space inside. Background technique [0002] Recently, high-speed elevators have been installed in skyscrapers in order to meet the demand for non-stop transportation and high-speed transportation to upper floors. The lift car of this high-speed elevator is provided with a pressure control system, and the setting of the control system is used to maintain a certain pressure in the car, thereby avoiding the rapid change of the pressure in the lift car and making passengers uncomfortable. The walls of the traditional elevator car are single-wall panels, so it is difficult to maintain the pressure in the car at a predetermined value. When the pressure inside the cage is cont...
