2. Description of the Related Art In recent years, with the rise of buildings, there has been a demand for increased comfort of rides as well as faster elevators. If the height of the building exceeds 300 m, passengers of the elevator may feel discomfort due to changes in the air pressure during ascent and descent. Also, when the speed of ascending and descending becomes extremely high, there is a possibility that the auditory function of the passenger is physiologically affected.
[0003]
Therefore, from the viewpoint of minimizing the above-mentioned effects, a pressure control device that changes the pressure inside the car according to the pressure outside the car has been proposed.
[0004]
In this elevator, as shown in FIG. 8, an air supply blower 2 for pressurizing the inside of the car 1 and an exhaust blower 3 for depressurizing the inside of the car 1 are provided above the car 1, and for example, from the top floor of a high-rise building When descending to the lowest floor at a stretch, in the first half of the descent, the air supply blower 2 is driven to control the pressure in the car 1, and in the second half of the descent, the exhaust blower 3 is driven to control the pressure in the car 1. It has a configuration.

[0019]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0020]
(First Embodiment)
FIG. 1 is a perspective view of a car for explaining an embodiment of an elevator ventilation device according to the present invention.
[0021]
In the figure, reference numeral 1 denotes a car 1 which carries passengers and moves up and down. The car 1 is provided so as to straddle a car floor 4, a side panel 5 erected on the car floor 4, and an upper part of the side panel 5. Ceiling 6 covered, entrance pillars 7 standing on both sides of the door opening at the front of the car, a car door panel 8 slidably provided at the door opening, and a gap between the upper part of the car door panel 8 and the ceiling 6 , And is assembled so as to maintain extremely high airtightness in order to realize airtight control of the inside of the car room.
[0022]
Further, an air supply blower 2 for pressurizing the inside of the car 1 and an exhaust blower 3 for depressurizing the inside of the car 1 are installed at the upper part of the car 1 as described above. , The blowers 2 and 3 are driven and controlled to change the amount of air inside the car, thereby controlling the air pressure in the car room.
[0023]
Further, the ceiling 6 of the car 1 is provided with at least one or more ventilation means 10.
[0024]
As shown in FIG. 2 which is a sectional view taken along the line AA in FIG. 1, one or more ventilation windows 11 formed in, for example, a square shape are opened at required locations on the ceiling 6. A window opening / closing device 12 is installed on the ceiling 6 side with the window 11 interposed therebetween, and a lock device 13 is also installed on the other ceiling 6 side with the ventilation window 11 interposed therebetween.
[0025]
The window opening / closing device 12 has a support block 12a having a required height, and a ventilation window which is rotatably mounted with the support block 12a as a fixed end, and provided with an engagement member 12b on the opposite side to the support block 12a. A plate 12c, a pulley 12d installed at an upper position of the ventilation window plate 12c, and a weight 12f suspended at an end of a wire 12e fixedly supported by the ventilation window plate 12c and suspended over the pulley 12d. It is configured.
[0026]
On the other hand, the lock device 13 includes an electromagnet 13a, an arm 13b that penetrates into and out of the electromagnet 13a, and an arm 13b that moves forward by the electromagnetic force of the electromagnet 13a when the normal power is supplied, thereby engaging the ventilation window plate 12c. An elastic member 13c is provided which engages and locks with the member 12b and retreats the arm 13b by its own elastic force to release the lock when the normal power supply fails.
[0027]
In addition, for example, a gasket 14 for maintaining airtightness is attached to an edge of the opening serving as the ventilation window 11 in order to maintain airtightness between the ceiling 6 and the ventilation window plate 12b.
[0028]
In such a ventilation means 10, when the regular power is supplied, as shown in FIG. 2A, the arm 13b moves forward by the electromagnetic force of the electromagnet 13a, and the arm 13b moves to the engagement member 12b attached to the ventilation window plate 12c. As a result, the ventilation window plate 12c is locked with the ventilation window 11 closed. At this time, since the ventilation window plate 12c is closed in a state where the airtight holding packing 14 is pressed, the inside of the car is in a sealed state.
[0029]
However, when the car 1 stops in the hoistway due to a failure of the elevator and the normal power supply is cut off, the electromagnetic force of the electromagnet 13a does not work, and conversely, the arm 13b retreats due to the elastic force of the elastic member 13c, and the arm 13b retreats. Is released from the engaging member 12b of the ventilation window plate 12c, and the lock is released. Therefore, the ventilation window plate 12c is lifted by the weight of the weight 12f suspended on the wire 12e suspended over the pulley 12d, and the ventilation is performed. The window 11 is opened, and the air in the car 1 can be ventilated.
[0030]
Therefore, according to the above-described embodiment, when a passenger is trapped in the car due to a power failure together with a stop due to a failure of the elevator, the electromagnetic force of the electromagnet 13a stops working upon receiving a power failure signal of the regular power supply, The arm 13b is disengaged from the engaging member 12b by the elastic force of the elastic member 13c, and the lock is released. Therefore, the ventilation window 11 is opened, and the air in the car circulates with the outside air to be set in a state of natural ventilation. Can be.
[0031]
Therefore, the passengers trapped in the car 1 do not run out of oxygen, and the passengers can feel secure or secure.
[0032]
(Second embodiment)
FIG. 3 is a perspective view of a car for explaining another embodiment of the elevator ventilation device according to the present invention.

It is constituted by a stopper device 23 for inserting the stop pin 23a to a. The long holes 21la and 21ha of the door opening range restricting members 211 and 21h have a length for restricting a door opening range of the car door panel 8 which can be opened by a passenger opening operation. That is, when the car door panel 8 is opened, the length of the long hole means a door opening range that allows ventilation with the outside but does not cause a dangerous condition for passengers in the car. is there.
[0035]
Also, at the time of a power failure of the regular power supply, a part of the output of the battery power supply device 22 is used to return to a regular power supply that opens and closes the car door panel 8 in a normal state, and the car door panel 8 is automatically moved within the regulated door opening range. It is also possible to adopt a configuration that can be opened.
[0036]
Therefore, in the ventilation means 10 as described above, when the elevator is operated, the elevator is operated in the same state as before, but when the elevator stops due to a failure and power supply from a regular power supply such as a control panel is stopped, The passenger is locked in the car.
[0037]
At this time, when power is not supplied from the regular power supply, the switch connected to the output line of the battery power supply device 22 is closed, so that the power from the battery power supply device 22 is supplied to the stopper device 23. As a result, the stopper device 23 operates to move the stop pin 23a forward, so that the stop pin 23a is inserted into the long holes 21la and 21ha formed in the two door opening range regulating members 211 and 21h. Therefore, when the passenger is in an uncomfortable state due to lack of oxygen or the like after this stop stage or when the opening operation of opening both car door panels 8 is performed, the long holes 21la and 21ha of the door opening range restricting members 211 and 21h are formed. The two car door panels 8 are opened by an amount corresponding to the above. An appropriate opening amount of the car door panel 8 is, for example, 10 to 15 cm so that there is no possibility that the passenger falls into the hoistway and ventilation of the car room is sufficiently maintained.
[0038]
FIG. 4 shows a state in which the stopper device 23 operates and the car door panel 8 is opened by a length restricted by the lengths of the long holes 21la and 21ha.
[0039]
As described above, when the power supply is stopped, if a part of the output of the battery power supply device 22 is reduced to the normal power supply for opening and closing the car door panel 8 within a predetermined time, the car door panel 8 is moved within the door opening range. Can be opened automatically.
[0040]
Therefore, according to the above-described embodiment, even when the passenger is confined in the car 1, the two car door panels 8 can be opened artificially or automatically, and thus, the inside of the car can be reliably assured. Ventilation can ensure passenger safety.
