The elevator in the evening lifts or descends in the hoistway of the building with passengers. If the difference in height exceeds 300 m after moving, passengers in the passenger car will feel uncomfortable with the change in air pressure during ascent and descent. At very high speeds, passengers begin to experience physiological effects on hearing function

To mitigate these effects, the vehicle may be equipped with a pressure control garment that regulates and controls the air pressure inside the vehicle or in the vehicle. A pressure control device includes a pressure port for pressurizing the rider and an exhaust port for discharging air and depressurizing the rider. By appropriately driving the exhaust fan, the air pressure in the car is adjusted according to the change in the external air pressure.

A passenger car equipped with such an air pressure control rf needs to have high passenger car tightness.However, if the passenger tightness of the passenger car is increased, passengers in the passenger car are closed. In such a situation, the power supply for evening operation is cut off due to a power outage, etc., causing a problem such as an emergency stop of the car. If power is supplied to the car, the inside of the car can be ventilated by the pressurization port and exhaust port D of the air pressure control device. The car has stopped in an emergency because the equipment could not be driven. + The ventilation inside the car is not allowed. As a result, the oxygen concentration in the car is lowered, which not only causes discomfort to the passengers, but also causes a problem in terms of safety if the condition is prolonged for a long time.

The door garment ia is equipped with a door panel, a door driving device, and a door release mechanism. The door panel opens and closes the door □ of the elevator car. The door driving device drives the door panel with electric power to open and close. The door release mechanism activates the door drive unit with the secondary battery and moves the door panel a predetermined distance in the door opening direction when the car is shut down due to an emergency shutdown of the power supply for elevator operation.

The elevator car door and door device are provided with a pair of door panels, door drive device, door release mechanism and ■ a. A pair of door panels opens and closes the entrance to the elevator car. The door driving device drives the pair of door panels with electric power to open and close. The door release mechanism detects that the car has been shut down due to the emergency shutdown of the power supply for the door operation. Move the panel in the door opening direction by a specified distance to create a specified gap between the door panels.

The door panel moves along the door rail provided in the car. In the middle of the door rail, there is provided a stepped section separated by a slope.The door panel in a door-closed state climbs from the lower section of the step to the slope, and moves to the upper section. The door is opened by moving. The door driving force of the door opening mechanism is smaller than the force of the door panel climbing up the slope.

The width of the gap between the panels opened by the door opening mechanism is preferably in the range of 50 to 200 mm.

When the door opening mechanism moves the door panel in the door opening direction by a predetermined distance, the door panel is provided with a regulating device for restricting the door panel from moving further in the door opening direction.

The control device includes a control pin driven by an electromagnetic actuator. The regulating pin is lifted upward while the electromagnetic actuator is energized, and moves downward by its own weight or the urging force of the urging member while the electromagnetic actuator is not energized.The regulating pin moves the door panel at the lower position.

As shown in FIGS. 2 to 5, a regulating device 30 is provided at the upper front of the car 1. 1A and 1B, the illustration of the regulating device 30 is omitted.

The regulating device 30 is provided with a frame 3 1 attached to the support plate 6. An electromagnetic actuator 32 is provided in the frame 31 provided with the electromagnetic wave. The frame 31 has a horizontal support base 35 and an end plate 36. These support bases 3 5 and end plates

A regulation pin 37 is provided to pass through 36. The upper end of the control pin 37 is connected to a plunger 38 driven by an electromagnetic actuator 32.

A flange member 40 is provided at an intermediate portion of the regulating pin 37. A spring 41 is provided as an urging member between the flange member 40 and the support base 35. . The regulating pin 37 is elastically urged downward by the spring 41.

A position detecting rod 44 is attached to the regulating pin 37, and a plate 45 is attached to the support base 35. The position detecting rod 44 of the regulating pin 37 penetrates a vertically long notch groove 46 formed on the plate 45 and projects to the front side thereof.

In the front of play 45, a notch

For example, a pair of optical sensors 48 a and 48 b arranged vertically along the line 46 is provided. The position of the position detecting rod 44, that is, the position of the regulating pin 37 is detected by these optical sensors 48a and 48b.

Hangers 1 1 a, 1 provided on each door panel 4 a, 4 b

Control plates 50a and 50b are attached to 1b, respectively. These restriction plates 50a and 50b are provided so as to protrude toward the front of the riding car 1 and to be vertically displaced from each other. Then, as shown in FIG. 1A and FIG. 2, the door panels 4a,

4b is a door-closed state in which the door edges on the front end side are in contact with each other, and as shown in Fig. 4, the regulating plate 50a of one door panel 4a is located on the side where the other door panel 4b is arranged. Then, the regulating plate 50b of the other door panel 4b projects to the side where the other door panel 4a is arranged. Accordingly, when the door panels 4a and 4b move in the direction in which the door panels 4a and 4b move away from each other, first of all, one regulating plate 50a and the other regulating plate 50b are arranged as indicated by arrows in FIG. Move in the direction of approaching each other.

Then, after moving by a certain distance, the one regulating plate 50a and the other regulating plate 50b pass each other, and then the one regulating plate 50a and the other regulating plate 50b are separated from each other. Move in the direction

Normally, the regulating pin 37 protrudes greatly below the grudge 36, and the regulating pin 50a of the door panel 4a in the closed state and the regulating plate 50b of the other door panel 4b are closed. It is in between. At this time, the distance L between the restriction pin 37 and the side edge of the one restriction plate 50a, and the distance L between the restriction pin 37 and the side edge of the other restriction plate 50b. Is, for example, 50 mm.

Next, the operation will be described.

During normal driving during the night, as shown in Figure 1A, the entrance 2 of the car 1 is closed by the panels 4a and 4b. Also, the electromagnetic device of the regulating device 30 is closed. In the evening, there is no electricity. The restriction pins 37 are used for weight and spring 4

As shown in Fig. 2 and Fig. 5, the control plate 50a of one door panel 4a and the other door are closed as shown in Fig. 5 and Fig. 5. The position of the control pin 37, which has entered between the control panel 50b and the control panel 50b of the sensor panel 4b, is determined by the fact that the position detecting rod 44 is detected by the optical sensor 48b. Have been recognized

When the traveling car 1 enters the predetermined landing zone, the electromagnetic actuator 32 is energized. Electromagnetic act — Evening 3

When 2 is energized, the plunger 38 is pulled upward by the electromagnetic force. The restricting pin 37 moves upward to the plunger 38 and the body, separates from between the restricting plates 50a and 50b, and is in a deregulated state. The position of the restriction pin 37 at this time is determined by the position detection rod 44 being detected by the optical sensor 48a.

When the car 1 has landed on the prescribed opening, the door panels 4a and 4b are driven by the door moving device 5 to move left and right as shown in Fig.1B. Then, the entry / exit □ 2 of car 1 is opened. After the passengers get on and off the passenger 1, the door panels 4 a and 4 b are driven by the driving device 5 to close the doorway 2, and the door panels 4 a and 4 b are closed. After that, the energizing of the electromagnetic actuator 32 is cut off.The regulating pin 37 is lowered integrally with the plunger 38 by its own weight and the urging force of the spring 41, and the doors 4a, 4 The door panels 4a and 4b, which enter between the restriction plates 50a and 50b of b, are kept in the closed state, and in this state, the riding force and the traveling of the driver 1 resume.

On the other hand, if the power supply 15 for overnight operation is cut off due to a power outage or the like while the ride 1 is running, and the ride 1 stops in an emergency, power supply to the door drive device 5 will be supplied. The system is automatically switched to the secondary battery 16 as an emergency power supply. The door drive unit 5 is activated by the electric power from the pond 16 and drives the door panels 4a and 4b in the door opening direction to open the gap 0 between the door edges of the door panel fl and the door panels 4 at 4b. Is produced.

Each of the hanger panels 4a and 4b is moved, for example, by about 40 mm in the direction of opening the door apart from each other.

1 2 b, 13 a t 13 b reach the slope 18 a of door rail 89 respectively

At this time, each of the wings 1 2 a, 1 2 b 1 3 a 1 3 b needs a force F to overcome the sloping section 18 a against the gravity, but powers the next battery 16. As a result, the driving force of the driving device 5 that is started up is sx. Therefore, the door panels 4a and 4b each move about 40 mm in the opening direction to reach the inclined portion 18a, and stop with a gap of about 80 mm therebetween.

If the power is cut off while the car 1 is running due to a power outage or the like and the car 1 is stopped in an emergency, the door panels 4a and 4b are automatically moved to the specified distance (40 mm). Each of them moves, and a predetermined gap (80 mm) is generated between the door panels 4a and 4b. Therefore, the air in the ride 1 is sufficiently circulated to the outside air through the gap, and there is no shortage of oxygen in the ride 1. There is no doubt that passengers in car 1 will be discomfort

Further, since a gap having a predetermined width is formed between the door panels 4a and 4b, the passenger in the car 1 can know the outside state through the gap. The passengers were locked in a closed room The feeling of terrifying feelings is reduced.

On the other hand, when the passenger in the car 1 tries to open the panels 4a and 4b by inserting his hand into the gap, the panel 4a

4b is moved by about 10 mm in the opening direction, and the regulating plate 50a50b comes into contact with the regulating pin 37, so that further movement is regulated. The gap between them is restricted to 100 mm or less, and the size is not open. Ride 1 can ensure safety without exposing passengers inside to the danger of falling from the gap

In addition, a driving force exceeding the force F is generated in the door driving device 5, and the hanger rollers 1 2a, 1 2b 1 3a 1

Even if the door panel 4a 4b moves further in the door opening direction after 3b gets over the inclined part 18a, the control plates 50a and 50b of the panel 4a 4b are also used as the control pins 3. 7 to restrict further movement. Therefore, door panels 4a and 4b cannot be opened widely. For this reason, the passengers in the vehicle or 1 are at risk of falling from the gap.

If the car 1 stops in an emergency, the door panel 4a 4b cannot be opened due to the failure of the secondary battery 16 It is possible to configure so that an announcement that prompts the passengers in the car 1 to open the door panels 4a and 4b manually using the announcer device is broadcasted.

In the second embodiment shown in FIGS. 6A and 6B, the driving device 5 is connected to a normal power supply. Just the emergency power supply is not connected

Winding devices 20a and 20b as biasing mechanisms are provided at both ends of the support plate 6, respectively. These winding devices 20a and 20b are composed of a reel 21, a spring 22 and a wire 23. The reel 21 is rotatably attached to the support plate 6. The spring 22 elastically urges the U-wheel 21 in one rotation direction. The wire 23 is a wire or the like having one end wound around the U-wheel 21 and the other end connected to eight fingers-11 a and 11 b of the door panels 4 a and 4 b.

The door panels 4a and 4b are elastically urged by the force of the spring 22 in the direction in which the door panels 4a and 4b are separated from each other via the wire rod 23, that is, in the door opening direction. Is a force that can move the door panels 4a and 4b in the recessed section 18 in the door opening direction, and the hanger 1

12b, 13a, and 13b are set to a smaller force than the force used when climbing the inclined portion 18a of the rails 8 and 9.

The door driving device 5 that drives the door panels 4 a and 4 b is configured to close the door panel when a predetermined electric signal is input.

The doors 4a, 4b are moved in the direction away from each other based on the electric power, and the doors are opened, and the door panels 4a, 4b in the opened state are taken up. ΌDevices 20a, 20b The door is closed by moving it in a direction approaching each other by stakes by the urging force of. Panel 4a when door is closed

4b, as long as power is supplied to the door drive device 5, the movement is restricted, the door is kept closed, and the door drive device 5

«Unlocks when supply of +1 is cut It should be noted that also in the cage door device 3 of the present embodiment, the regulating device 30 having the same configuration as that shown in FIGS. 2 to 5 is ax shifted. Therefore, the operation will be described with reference to FIGS.

During normal driving in Erebet, as shown in Fig. 6A, the entrance 2 of the car 1 is closed by door panels 4a and 4b. The electromagnetic function 32 of the regulating device 30 is not energized. Regulator pins 3 7 are white and spring 4

As shown in FIGS. 3 to 5, the door is closed with the urging force of 1 and the door 50 is closed and the control panel 50a of the door panel 4a and the control panel 50 of the other door panel 4b are closed. The position of the control pin 37 at this point is located between the position detection rod 44 and the light sensor 48b.

When the traveling car 1 enters the predetermined landing zone, the electromagnetic actuator 32 is energized, and the electromagnetic actuator 32 is energized. The jaws 38 are attracted upward by the electromagnetic force. The regulating pin 37 moves upward together with the plunger 38 and separates from the regulating plates 50a and 50Ob. As a result, the restriction device 30 is in the restriction release state. At this time, the position of the regulation pin 37 is recognized by the position sensor rod 44 being detected by the optical sensor 48a.

When the car 1 has landed on the predetermined floor, the door panels 4a and 4b are driven by the door driving device 5 to move left and right as shown in FIG. 6B. Open the entrance 2 of the car 1 After passengers have entered and exited car 1, Door panels 4a and 4b are driven again by door drive device 5 to close doorway 2.Electromagnetic actuator 32 is turned off after this closing.Regulatory pin 37 is integrated with plunger 38. As a result, the car 1 descends with its own weight and the urging force of the spun wing 41 and enters between the regulating plates 50 a 50 b of the door panel 4 a 4 b. Keep the door closed and restart running in this state.

The wire 23 of the winding device 20a20b is wound around the reel 21 by the biasing force of the opening spring 22 where the door panel 4a4b moves in the door opening direction. When the panel 4a 4b moves in the door closing direction, it is fed out of the U-rule 21 against the urging force of the α-spring 22.

On the other hand, if the car 1 stops in an emergency while the car 1 is running due to power cutoff due to a power failure, etc., the door panel 4a4b is restrained by the door drive device 5 because the power is cut off. Disappear.

The door panels 4a and 4b are elastically urged in the door opening direction apart from each other by the take-off devices 20a and 20b. Accordingly, when the restraint on the driving device 5 is lost, the rear panels 4a and 4b are moved in the opening direction by the urging force of the winding devices 20a and 20b in response to the release of the restraint. If the door panels 4a and 4b move apart by about 40 mm, for example, in the door opening direction where they are separated from each other, each hanger-D-layer 1 2a, 1 2b 1 3a and 13b respectively reach the slope 18a at door rail 89 At this time, each of the eight rollers 1 2a 1 2b 13 3a and 13b requires a force F to cross the inclined portion 18a against the gravity against the force D, but the winding device 2 The elastic biasing force due to 0a20b is preset to a value smaller than the force F. Therefore, the doors 4a and 4b open in the opening direction.

Move about 40 mm to make the slope 18 a

When a gap of about 0 mm is generated, the movement is stopped.

As described above, when the power is cut off due to a power failure or the like while the car 1 † is traveling, the car panel 1 automatically stops when the car 1 is stopped. mm) and a predetermined gap (80 mm) is created between them, so that the air in the car 1 is sufficiently circulated through the gap with the outside air. As a result, the inside of car 1 is properly ventilated, and there is no danger of lack of oxygen. The passengers in car 1 do not experience any discomfort.

Also, a gap of a predetermined width is formed between the door panels 4a and 4b, so that the passengers in the car 1 can know the outside state through the gap, and there is a fear of being trapped in a closed room. Relieve.

On the other hand, the passenger in the car 1 tries to open the door panels 4a and 4b by inserting their hands into the gaps.

Reference numeral 4b denotes the movement in the opening direction of about 10 mm, and the restriction plate 50a50b of the door panel 4a4b comes into contact with the restriction pin 37 to restrict further movement. Therefore, the gap between the door panels 4a and 4b is restricted to 100 mm or less. As a result, the passengers in the car 1 are not exposed to the danger of falling from the gap, and safety is ensured.

The force by which the winding devices 20a and 20b move the door panneliles 4a and 4b horizontally in the door opening direction changes according to the angle of the wire 23 with respect to the horizontal. That is, when the angle of the wire 23 is small with respect to the horizontal, the horizontal component for moving the door panels 4a and 4b is large, and as the angle of the wire 23 becomes large with respect to the horizontal, the door panel 4 The horizontal component that moves a and 4b becomes smaller.

Here, the angle of the wire 23 of the winding device 20 a 20 b with respect to the horizontal is small when the door panel 4 a 4 b is in the door closed state, and the door panels 4 a, 4 b The angle gradually increases as the door moves in the opening direction

Therefore, the door panels 4a and 4b receive a large horizontal component force at the start of the door opening and start the door opening operation accurately. Door panel

As 4a and 4b move in the direction of opening the door, the horizontal component gradually decreases. For this reason, when the swing rollers 12a, 12b, 13a, and 13b reach the inclined portion 18a of the door rail 89, the door panels 4a and 4b stop properly. Do

A third embodiment is shown in FIGS. 7A and 7B. In this embodiment, when the power supply to the door drive device 5 is cut off, the door panels 4a and 4b in the door-closed state are moved by a predetermined distance in the door-opening direction, and a tension mechanism is used. Springs 60a and 60b are used One end of each of the tension springs 60a and 60b is engaged with the support plate 6 on the front surface of the cage 1, and the other end of the extension spring 60a and 60b of the door panels 4a and 4b. Locked to b. Door panel 4 a,

4b is elastically urged in the direction of opening the door which is separated from each other by the elastic force of the tension springs 60a and 60b. 4a and 4b are forces that can move the doors in the direction of opening the doors between the recesses 18 and the hanger openings 12a, 12b, 13a, and 13b Ax At e is smaller than the force required to get on the slope 18 a of the door rails 8 and 9

Therefore, in the third embodiment, the same operation and effect as those of the second embodiment can be obtained.

The fourth embodiment is different from the embodiment shown in FIGS. 8A and 8B in that when the power supply to the door drive device 5 is cut off, the door panels 4 a and 4 b which are in the door closed state are opened. Weights 6 la and 61 b are used as urging mechanisms for moving a predetermined distance in the direction.

The pulleys 62 are rotatably provided at both ends of the support plate 6 on the front surface of the car 1. A wire 63 such as a wire is wound around the pulley 62. One end of the wire rod 63 is locked to the hangers 11a and lib of the door panels 4a and 4b. The other end of the wire 63 is attached to the weights 6la and 6lb. The door panels 4a and 4b are urged in the door opening direction apart from each other by the weight of the weights 6la and 61b.

This biasing force causes recessed door panels 4a and 4b in the closed state. It is the force that can be moved in the door opening direction in the section of section 18 and can be moved to the door hanger 1 2 a, 1 2 b 1 3 a 1

3b is set to a smaller force than that required when riding on the slope 18a of the rail 89

Therefore, in the fourth embodiment, the same effects as those of the second embodiment can be obtained.

In any of the embodiments, taking into account the condition that the passengers can switch inside the passenger car 1 sufficiently and ensure the safety for the passengers, the door panel 4 in the emergency stop of the passenger car 1 The width of the gap formed between a 4 b is preferably in the range of 500 mm.

As described above, according to the present invention, when the power supply for overnight operation is shut down due to a power failure or the like and the car is stopped in an emergency, the door panel of the car is moved only within a predetermined safe range. It opens white and ventilates the inside of the vehicle.
