The elevator E of the 1st embodiment has the supply ventilating fan 7 carry passenger's lift car 1 and be used for controlling the Pneumatic controller of lift car 1 air pressure inside of being used for of oscilaltion.
The shape of lift car 1 is provided on the above-below direction long cuboid, it has the side panel 2 of the four direction that is arranged on the side, from the floor 3 of lower support side panel 2, be arranged on the ceiling 4 on side panel 2 tops and be arranged on the side panel 2a that is positioned at lift car 1 front side and go up and can slide and the elevator door 5 of (the opening and closing in the direction shown in the arrow γ 1 of Fig. 1) that open and close.
In lift car 1, the containment member 6 in the gap that produces between elevator door 5 and side panel 2 by side panel 2, floor 3, ceiling 4, elevator door 5 and when being used for being blocked in elevator door 5 and closing waits to keep its leak tightness.
In order to control the air pressure inside that this has bubble-tight lift car 1, above ceiling 4, be provided with the supply ventilating fan 7 that lift car 1 air outside is sent to lift car inside, by adjusting the amount of air of sending into lift car 1 with supply ventilating fan 7, the air pressure inside of lift car 1 is controlled.
The side panel 2b of lift car 1 is provided with under the abnormal condition (outage) that stop in power supply for the elevator drafting apparatus 8 that lift car 1 is ventilated.This elevator drafting apparatus 8 is covered by outer cover 8c.
The structure of＜elevator drafting apparatus 8 〉
Fig. 2 is the section-drawing of direction shown in the arrow A of Fig. 1, and expression is arranged on the inner structure of the elevator drafting apparatus 8 on the lift car 1.In Fig. 2, the outer cover 8c of elevator drafting apparatus 8 is represented by long and two-short dash line.
Wherein, the straight-line motion that will close with the switching axle 15 of screw actuator 14 by slotted hole etc. of connecting rod mechanism 21 is transformed to rotatablely moving of ventilation window open and close member 17.
Open and close axle 15 and when closing with screw actuator 14 connections, under the effect of the magnetic force of electromagnetic induction, move (with reference to the solid line of Fig. 2) towards the direction shown in the arrow α 3 of Fig. 2, on the other hand, when closing with screw actuator 14 disconnections, electromagnetic induction disappears, open and close axle 15 and under the elastic force effect of compression spring 16, move towards the direction shown in the arrow α 2 of Fig. 2, thereby open ventilation window open and close member 17 (with reference to the long and two-short dash line among Fig. 2).
In the above description, the occasion that is positioned at the position that connects with the ventilation window open and close member 17 of closing ventilation window with step switch 19 above ventilating with peristome k is that example is described, if but can bring into play predetermined function described later, does not then limit the position that arranges of step switch 19.
Be specifically, step switch 19 is provided in to connect closes with the power supply of screw actuator 14 normally in service after ventilation window open and close member 17 is closed, the movable terminal 19O of step switch 19 contacts with terminal 19A, connect the power supply (electric current 19a) that screw actuator 10 is used in locking with this, movable terminal 19O separates with terminal 19B simultaneously, disconnects the power supply of closing with screw actuator 14 with this.Among the figure, the movable terminal 19O of step switch 19 by towards the direction that contacts with terminal 19B (towards the below of Fig. 2) application of force, when accepting the normal operation of power supply, accepts power supply by not shown connection lead by elastic component.
On the other hand, when abnormal condition (outage) have taken place, because movable terminal 19O and terminal 19A via step switch 19 are supplied to locking to disconnect with the power supply of screw actuator 10, so lock shaft 11 moves towards the direction shown in the arrow α 1 of Fig. 2 under the effect of compression spring 12, lock shaft 11 retreats into the latch-release position of being represented by the long and two-short dash line of Fig. 2.For this reason, opening and closing axle 15 moves towards the direction shown in the arrow α 2 of Fig. 2 under the effect with the elastic force of the compression spring 16 of screw actuator 14 of closing that is in off-state, by opening and closing the action of axle 15, connecting rod mechanism 21, ventilation window open and close member 17 is opened to the open position of being represented by the long and two-short dash line of Fig. 2 (shown in the arrow β 1 of Fig. 2).
In addition, in elevator drafting apparatus 8, sealing member 20 is arranged on the side panel 2b, when ventilation window open and close member 17 is in closed condition, and the airtight conditions that the seal 20 keeps between ventilation window open and close member 17 and the side panel 2b.
As shown in Figure 2, sealing member 20 is arranged on the side panel 2b, its be in ventilation window open and close member 17 butts of closed condition, and the ventilation that is positioned at side panel 2b is with around the peristome k.
Thus, when ventilation window open and close member 17 is in closed condition, sealing member 20 contacts with the circumference of ventilation window open and close member 17, makes lift car 1 keep airtight conditions at ventilation window open and close member 17 and between ventilating with the side panel 2b around the peristome k.
＜when normal use normal power source in service is powered 〉
In elevator drafting apparatus 8, when powering (accepting the power supply power supply) at normal use normal power source in service, as shown in Figure 2, the movable terminal 19O of step switch 19 contacts with terminal 19A, uses screw actuator 10 power supplies (the electric current 19a of Fig. 2) by normal power source to locking.By making locking with screw actuator 10 energising, lock shaft 11 is locked to be attracted with screw actuators 10, move towards the direction shown in the arrow α 4 of Fig. 2, and advance to ventilation window open and close member 17 outsides with ventilation window open and close member 17 opposed positions.Thus, lock shaft 11 can stop the opening action (towards the action of direction shown in the arrow β 1 of Fig. 2) of ventilation window open and close member 17, and ventilation window open and close member 17 is locked in closed condition.
At this moment, be separated from each other by movable terminal 19O and the terminal 19B that makes step switch 19, the power supply of closing with screw actuator 14 is disconnected, thus can brownout.
In addition, after closing with screw actuator 14 disconnections, be used for closing the application force disappearance that closing of ventilation window open and close member 17 used screw actuator 14, but because lock shaft 11 can stop the opening action (with reference to Fig. 2) of ventilation window open and close member 17, so ventilation window open and close member 17 can not opened.
When normal use normal power source in service is powered, control the air pressure inside of lift car 1 by the air-supply of supply ventilating fan 7.
＜(during outage) when unusual taken place 〉
When the normal power source that uses when normal operation is stopped power supply (during outage), supply ventilating fan 7 is out-of-blast.Because lift car 1 is in airtight conditions, so anoxia phenomenon may appear in the passenger in the lift car 1.
Therefore, adopt method as described below that the ventilation window open and close member 17 of elevator drafting apparatus 8 is opened, in order to lift car 1 is ventilated.
When the normal power source that uses when normal operation was stopped power supply, the movable terminal 19O of step switch 19 shown in Figure 2 contacted with terminal 19A, was fed to the electricity (electric current 19a) that locks with screw actuator 10 and was disconnected.
After power supply is disconnected, quit work with screw actuator 10 owing to lock, so shown in the arrow α 1 of Fig. 2, the engagement section 11a of lock shaft 11 is compressed the elastic force of spring 12 and presses.For this reason, lock shaft 11 retreats towards the direction shown in the arrow α 1, the ventilation window open and close member 17 that is in closed condition is opened, thereby made ventilation window open and close member 17 be in unlock state.
At this moment, because movable terminal 19O and the terminal 19B of step switch 19 is in contactless state, and power supply is disconnected, and do not close with screw actuator 14 so there is electric current to flow through.For this reason, the snap portions 15a that opens and closes axle 15 is pressed towards the direction shown in the arrow α 2 of Fig. 2 under the effect of the elastic force of compression spring 16, makes to open and close axle 15 and retreat towards the direction shown in the arrow α 2.At this moment, open and close axle 15 and connecting rod mechanism 21 interlocks, make ventilation window open and close member 17 (direction shown in the arrow β 1 of Fig. 2) rotation against the sun, ventilation window open and close member 17 is opened (with reference to the long and two-short dash line among Fig. 2).
So, the ventilation of lift car 1 is opened with peristome k, thereby lift car 1 is ventilated.
When the normal power source of＜use when normally moving restores electricity 〉
After the normal power source that uses when normal operation restored electricity, ventilation window open and close member 17 was closed to ventilate by following method and is used peristome k.
When abnormal condition (outage) have taken place, because ventilation window open and close member 17 is in open mode (with reference to the long and two-short dash line of Fig. 2), so the movable terminal 19O of step switch 19 and terminal 19B are in contact condition.After beginning power supply, electric current 19b flows via movable terminal 19O, the 19B of step switch 19, makes to close with screw actuator 14 energisings.After closing with screw actuator 14 energisings, opening and closing axle 15 overcomes the elastic force (elastic force of direction shown in the arrow α 2 of Fig. 2) that compresses spring 16 and moves towards the direction shown in the arrow α 3 of Fig. 2 under the effect of closing with the magnetic force of screw actuator 14, make and open and close (direction shown in the arrow β 2 of Fig. 2) rotation and close to ventilate and use peristome k with the sun of axle 15 and the ventilation window open and close member 17 of connecting rod mechanism 21 interlocks, stop up to ventilate with this and use peristome k (with reference to Fig. 2).
By ventilation window open and close member 17 make ventilate close fully with peristome k after, the movable terminal 19O of step switch 19 is pressed by ventilation window open and close member 17 and contacts (with reference to Fig. 2) with terminal 19A.At this moment, electric current 19a flows to locking with screw actuator 10 via movable terminal 19O and the terminal 19A of step switch 19, makes locking be in "on" position with screw actuator 10.Locking produces magnetic force with screw actuator 10 energising backs, lock shaft 11 overcomes the elastic force (elastic force of the direction shown in the arrow α 1 of Fig. 2) of compression spring 12 and moves towards the direction shown in the arrow α 4 of Fig. 2 under the effect of this magnetic force, ventilation window open and close member 17 is pinned (with reference to Fig. 2).
At this moment, movable terminal 19O and the terminal 19B of step switch 19 become contactless state, close with screw actuator 14 because electric current 19b no longer flows to, and quit work so close with screw actuator 14.So, when normal use normal power source in service is powered, close with screw actuator 14 no powers.
After the normal power source that uses when normal operation restored electricity, the ventilation of side panel 2b was closed by ventilation window open and close member 17 with peristome k, and the ventilation to lift car 1 that has taken place to carry out when unusual is stopped.
When normal (usually) operation, even have draught head between lift car 1 inside and outside, need be by the operating effort of locking with screw actuator 10 yet, and can utilize the bending stiffness that comprises of lock shaft 11 to overcome the elastic force that compresses spring 16 in interior rigidity, ventilation window open and close member 17 is maintained closed condition.That is to say, when normal operation, will be arranged on ventilation window open and close member 17 pinnings on the side panel 2b of lift car 1 with the rigidity of the lock shaft 11 of screw actuator 10 by locking.
When normal use normal power source in service is powered, as mentioned above, control the air pressure of lift car 1 inside by making supply ventilating fan 7 air-supplies.
＜effect and effect 〉
According to said structure, when having a power failure, open by the ventilation window open and close member 17 that makes elevator drafting apparatus 8, can avoid the passenger who is closed in the lift car 1 anoxia phenomenon to occur.
On the other hand, behind service restoration, do not need to wait for that maintainer etc. manually recovers, ventilation window open and close member 17 is resetted, thereby can make elevator E successfully return to normally (usually) operation.
In addition, when normal (usually) operation, can not be subjected to the influence of the draught head between lift car 1 inside and the outside, can reliably ventilation window open and close member 17 be maintained closed condition.

The movable terminal 32O of step switch 32,, is powered by not shown connection lead when normal operation towards the direction of leaving terminal 32A (downward direction of the paper of Fig. 4) application of force by elastic component.
In the above description, the occasion that is positioned at the position that connects with the ventilation window open and close member 37 that is in closed condition with step switch 32 above ventilating with peristome k is that example is described, if but can bring into play predetermined function described later, does not then limit the position that arranges of step switch 32.
In having the elevator drafting apparatus 30 of said structure, when closing the ventilation window open and close member 37 that is in open mode, the trapezoid part 25 that is in the ventilation window open and close member 37 (being represented by dotted lines) of open mode in Fig. 4 is pressed by the roller 27 (being represented by dotted lines in Fig. 4) that carries out opening operation (direction shown in the arrow γ 21 of Fig. 4) on the elevator door 5, thereby ventilation window open and close member 37 is closed.
At this moment, pressed by ventilation window open and close member 37 and with after terminal 32A contacts at the movable terminal 32O of step switch 32, the normal power source that uses when normally moving by movable terminal 32O and terminal 32A to locking with screw actuator 23 power supplies.Locking is connected and generation magnetic force with screw actuator 23, lock shaft 28 is (on the direction shown in the arrow α 5 of Fig. 4) in the outside that advances to ventilation window open and close member 37 under the effect of this magnetic force, and with the tapering part 26t butt of the member 26 of ventilation window open and close member 37, lock ventilation window open and close member 37 (with reference to Fig. 4) thus.As mentioned above, ventilation window open and close member 37 is pinned reliably by lock shaft 28.
When the normal power source that uses is powered, control the air pressure inside of lift car 1 by the air-supply of supply ventilating fan 7 by normal operation the time.
Below the action of elevator drafting apparatus 30 is elaborated.
＜when the normal power source of normal use in service is stopped power supply 〉
When the normal power source that uses when causing normally moving in that the unusual state of affairs has taken place was stopped power supply, supply ventilating fan 7 was out-of-blast, because lift car 1 is in airtight conditions, therefore need avoid the passenger in lift car 1 anoxia phenomenon to occur.
Therefore, for lift car 1 is ventilated, adopt method as described below that ventilation window open and close member 37 is opened.
After the power supply of normal power source stopped, the movable terminal 32O of step switch 32 contacted with terminal 32A, made locking be disconnected with the power supply (electric current 32a) of screw actuator 23.
After locking was disconnected with the power supply of screw actuator 23, lock shaft 28 moved towards the direction shown in the arrow α 6 of Fig. 4 under the elastic force effect of compression spring 24, thereby releasing is in the locking of the ventilation window open and close member 37 of closed condition.
