no. 1 Embodiment approach

[0050] figure 1 It is a perspective view showing a schematic configuration of an elevator car 10 according to the first embodiment of the present invention. exist figure 1 Among them, the car 10 is observed from the upper side of the back (the side opposite to the elevator door 15 through which passengers get on and off). The car 10 is arranged in the elevator shaft so as to be able to move up and down.

[0051] Such as figure 1As shown, the car 10 is equipped with side panels 12 on the side and rear of the front panel 11 provided with the elevator door 15, and the upper and lower sides of these panels 11, 12 are sealed by a sealing plate 13 (ceiling) and a car floor plate 14 (floor). Create a space for passengers to board. A blower 18 as an air pressure control device is provided on the sealing plate 13 to supply and discharge air inside the car 10 to control the air pressure of the car 10 .

[0052] The base member 16 is provided between the side panel 12 , the seal pla...

no. 2 Embodiment approach

[0083] In the above-mentioned embodiment, it is configured that one opening and closing member 23 is operated by two self-holding solenoids 21, 21, but it may be as follows: Figure 9 As shown, one self-holding solenoid 21 is arranged for one opening and closing member 23 . In this case, the ventilation port A and the opening and closing member 23 are formed smaller than those in the first embodiment, which is suitable for reducing the load on each self-holding solenoid 21 . In addition, what is necessary is just to increase the number of ventilating port A compared with 1st Embodiment by the ratio by which ventilating port A is reduced.

Abstract

The invention provides an elevator for realizing automatic opening and closing of an emergency ventilation port formed in a car by using lower power consumption. In the elevator with an opening and closing device for opening and closing the ventilation port formed in the car through an opening and closing component; the opening and closing device is provided with an opening and closing mechanism and a control mechanism; the opening and closing mechanism comprises a rod part connected with the opening and closing component, and a self-hold solenoid; the self-hold solenoid is provided with a first electromagnetic coil and a second electromagnetic coil axially arranged on the inner side of a hollow cylindrical magnetic yoke side by side, a permanent magnet arranged between the first electromagnetic coil and the second electromagnetic coil, and a plunger capable of moving along the axis of the magnetic yoke and contacted with the rod part; and the control mechanism is provided with a power storage unit for charging at the power supply beginning of a power supply, and a control circuit for enabling the current to flow through the first electromagnetic coil by given time and supplying the current to the second electromagnetic coil from the power storage unit at the power supply stop time of the power supply.

Description

technical field [0001] The present invention relates to an elevator provided with an opening and closing device for opening and closing an emergency ventilation port provided in a car by an opening and closing member. Background technique [0002] In recent years, various high-speed elevators that raise and lower the car at a speed of hundreds of meters per minute have been proposed along with the high-rise building. In such an elevator, in order not to cause discomfort to passengers due to sudden changes in air pressure during ascent and descent, the air pressure in the car is adjusted by an air pressure adjustment device such as a blower that sucks and exhausts air in the car. [0003] In order to control the air pressure in the car to an optimum state, it is necessary to use a car having a highly airtight structure. On the other hand, if the airtightness is improved, when the power supply is stopped due to a power failure or the like to stop the operation of the air pres...
