Detailed Description
Hereinafter, embodiments of the present invention will be described based on the drawings.
Example 1
Fig. 1 is a schematic configuration diagram of an elevator apparatus according to an embodiment of the present invention.
The car 1 has side plates 2 provided laterally in four directions, a bottom plate 3 supporting the side plates 2 at a lower portion, a top plate 4 provided at an upper portion of the side plates 2, and an openable and closable door 5 provided at the side plate 2 at a front side of the car 1. The car 1 is configured to maintain airtightness.
in order to control the air pressure inside the airtight car 1, a blower 6 for sending the air outside the car 1 to the inside thereof, a chamber 7, a duct 8, and a diversion chamber 9 are provided on the top of the ceiling 4, and the air pressure inside the car 1 is controlled by adjusting the amount of air flowing into the car 1 by the blower 6. Further, a ventilation vent is formed in a side wall portion of the diversion chamber 9 disposed on the top portion of the car 1. A ventilator 10 capable of opening and closing a ventilation vent is attached to a side wall portion of the branch chamber 9. The ventilation device 10 is configured to open the ventilation vent to communicate the inside and outside of the car 1 for ventilation in an emergency where power supply is stopped, as described in detail later.
Fig. 2 is a front view of the ventilation device 10. Fig. 2 is a view seen from M of fig. 1 in the direction of arrow 100.
The ventilation device 10 has a structure for opening and closing a ventilation vent for ventilation that communicates the inside and the outside of the car 1 in an emergency situation in which power supply is interrupted, the ventilation vent including: a cover member 11 capable of opening and closing the ventilation vent; a lid member opening/closing drive device 12 for opening/closing the lid member 11; and a lid member electromagnetic locking device 14 that locks the lid member 11 in the closed state in the normal state and releases the locking of the lid member 11 in an emergency in which power supply is stopped.
The lid member 11 is formed on a base 16 disposed substantially vertically on a side wall portion of the distribution chamber 9 so as to open and close a ventilation vent formed on the side wall portion of the distribution chamber 9. The lid member 11 is attached to the base 16 of the ventilator 10 so as to be rotatable about a pair of hinge portions 17 extending in the vertical direction. Therefore, when the direction of arrow 100 is viewed from M in fig. 1, the lid member 11 does not rotate in the vertical direction, but rotates to the front side with the hinge portion 17 as the center, and therefore the opening/closing operation force is small.
The lid member opening/closing drive device 12 includes: a lid member closing electromagnetic drive device that is excited by the normal state of power supply to drive the lid member 11 to a closed state and hold the closed state; and an opening spring device 13 for opening the lid member 11 when the lid member closing electromagnetic drive device is demagnetized. The lid member opening/closing drive device 12 is disposed on a support member 18 supported on the front surface side of the base 16 of the ventilation device 10, and includes a drive shaft 19 axially movable at the center portion thereof, and a link 20 connecting the drive shaft 19 and the lid member 11. The opening spring device 13 is disposed between the drive shaft 19 and the support member 18, and applies a force to the drive shaft 19 in a direction to open the cover member 11.
In the normal state, a solenoid, not shown, of the lid member opening/closing drive device 12 is excited, and the closed state of the lid member 11 is held against the force of the opening spring device 13. However, in an emergency situation where the power supply is stopped, the solenoid, not shown, of the lid member opening/closing drive device 12 is demagnetized, and therefore the lid member 11 is turned by the opening spring device 13 via the hinge 17 to be opened. Since the lid member 11 is rotated toward the front side with the hinge portion 17 as a center and always maintaining a substantially vertical plane as described above, the opening/closing operation force of the lid member opening/closing drive device 12 and the opening spring device 13 can be reduced as compared with the vertical opening/closing system.
The lid member electromagnetic locking device 14 is configured to include a releasing spring device 15 that is excited in a normal state to hold the lid member 11 in a closed state and releases the locked state of the lid member 11 when demagnetized. The lid member electromagnetic lock device 14 is disposed on a support member 21 supported on the front surface side of the base 16, and has a drive shaft 22 movable in the axial direction at the center portion thereof. The releasing spring device 15 is disposed between the drive shaft 22 and the support member 21, and applies a force to the drive shaft 22 in a direction to release the lock of the cover member 11.
In the normal state, a solenoid, not shown, of the lid member electromagnetic locking device 14 is excited, and the mechanical locking state is maintained so that the lid member 11 does not open against the force of the releasing spring device 15. However, in an emergency where the power supply is stopped, since the solenoid, not shown, of the releasing spring device 15 is demagnetized, the locked state of the lid member 11 is released by the releasing spring device 15, and the lid member 11 is driven to open by the opening spring device 13.
Further, an airtight member 23 for keeping an outer peripheral portion of the ventilation vent in an airtight state is annularly disposed between a facing portion of the base 16 of the ventilator 10 and the mounting wall surface of the diversion chamber 9, and the airtight member 23 prevents the blower 6 from impairing the air quantity adjustment control in the car 1.
In this way, in the normal state, the lid member 11 is kept closed, and the amount of air flowing into the car 1 is adjusted by the blower 6 shown in fig. 1, thereby controlling the air pressure in the car 1. However, in an emergency where the power supply is stopped, the blower 6 is stopped, the cover member 11 of the ventilator 10 is opened, and the ventilation vent that communicates the inside and the outside of the car 1 is opened to perform ventilation.
Further, the ventilator 10 shown in fig. 2 has a horizontal vibration preventing member 24 annularly arranged inside the airtight member 23 between the base 16 of the ventilator 10 and the horizontally facing portion of the installation wall surface of the diversion chamber 9 when installed in the diversion chamber 9. The horizontal vibration isolating member 24 is held by a plurality of horizontal support bolts 25 that limit the amount of displacement in the horizontal direction, which is the thickness direction, to a certain value.
That is, between the facing portions of the base 16 of the ventilator 10 and the mounting wall surface 28 of the diversion chamber 9, facing portions are formed in the horizontal direction (the front-rear direction in the figure), and between the facing portions, the horizontal direction vibration isolation member 24 that can be displaced so as to increase or decrease the thickness dimension is disposed. The horizontal vibration isolating member 24 is held by a horizontal support bolt 24 that limits the horizontal displacement in the thickness direction thereof to a certain value.
The ventilator 10 has a vertical vibration isolating member 26 between the base 16 of the ventilator 10 and a vertically facing portion of the installation wall surface of the diversion chamber 9 when installed in the diversion chamber 9. The vertical vibration isolating member 26 is held by a plurality of vertical support bolts 27, the vertical displacement amount of which in the thickness direction is limited to a certain value.
That is, opposing portions opposing each other with a gap in the vertical direction (the vertical direction in the figure) are formed between the upper end portion of the base 16 of the ventilator 10 and the upper end portion of the mounting wall surface 28 of the diversion chamber 9, and the vertical-direction vibration-damping member 26 displaceable so as to increase or decrease the thickness dimension is disposed in the gap between the opposing portions. The vertical support bolt 27 is inserted from the side of the mounting wall surface 28 located above the base 16.
The horizontal vibration isolation member 24 and the vertical vibration isolation member 26 are displaced in the thickness direction thereof to provide a vibration isolation effect, and are displaced on the ventilator 10 side, particularly, when the cover member electromagnetic locking device 14 is rapidly operated, to provide a vibration isolation effect, thereby absorbing or attenuating impact vibration generated by the cover member electromagnetic locking device 14.
The horizontal support bolt 24 and the vertical support bolt 27 are, for example, shoulder bolts, and are inserted in an unthreaded state into an insertion hole formed in advance in the base 16 and the mounting wall surface 28 and an insertion hole formed in advance in the horizontal direction vibration isolating member 24 and the vertical direction vibration isolating member 26, and a threaded portion formed at the insertion side tip thereof is screwed into the mounting wall surface 28 and the base 16 to be in a threaded state. Therefore, in the non-screw-fit state, the horizontal vibration isolation member 24 can be displaced in the thickness direction of the horizontal vibration isolation member 24 to move the base 16 and the mounting wall surface 28 closer to or away from each other by a constant displacement amount. Similarly, the vertical direction vibration isolating member 26 can be displaced in the thickness direction of the vertical direction vibration isolating member 26 so as to be moved closer to or away from the base 16 and the mounting wall surface 28 by a constant displacement amount.
on the ventilator 10 side, impact vibration occurs when the lid member 11 is opened and closed by the lid member opening and closing drive device 12 and when the lid member 11 is locked or unlocked by the lid member electromagnetic locking device 14. If the impact vibration or the impact sound is also transmitted into the car 1 at this time, if there is a passenger in the car in an emergency where the power supply is stopped, the passenger may feel more uncomfortable with the impact vibration or the impact sound.
however, even if an impact occurs on the ventilator 10 side and an impact in the axial direction of the horizontal support bolt 25 is transmitted to the diversion chamber 9 side, the horizontal vibration isolation member 24 is displaced in the thickness direction by the lost motion (lost motion) of the horizontal support bolt 25, and the impact is absorbed or suppressed. Therefore, even if there is a passenger in the car in an emergency where power supply is stopped, the passenger can be prevented from being further disturbed by the vibration or the impact sound. Similarly, even if an impact occurs on the ventilator 10 side and an impact in the axial direction of the vertical support bolt 27 is transmitted to the diversion chamber 9 side, the vertical vibration isolation member 26 is displaced in the thickness direction thereof by the lost motion of the vertical support bolt 27 and the influence of the impact is absorbed or suppressed. Therefore, even if there is a passenger in the car in an emergency where the power supply is stopped, the passenger can be prevented from feeling more uneasy due to the vibration or the impact sound.
Example 2
Fig. 3 is a front view of an elevator apparatus according to another embodiment of the present invention. Fig. 3 is a view seen from M of fig. 1 in the direction of arrow 100. Fig. 6 is a view of the multidirectional base 29 viewed from the z direction.
In the previous embodiment, the horizontal direction vibration-proof member 24 and the vertical direction vibration-proof member 26 are provided at the coupling portion of the ventilator 10 and the diversion chamber 9, whereas in the present embodiment, the multidirectional base 29 is provided between the ventilator 10 and the base 16 and the cover member electromagnetic locking device 14, and on the multidirectional base 29, the vibration-proof members 31 are arranged between the support member 21 and the opposing portion 30 in the X direction, the Y direction, and the Z direction which are perpendicular to each other in the three-dimensional plane, respectively. Hereinafter, the description will be given with reference to fig. 3 or 6.
The support member 21 of the lid member electromagnetic locking device 14 is not directly fixed to the base 16, but a multidirectional base 29 is first fixed to the base 16, and the support member 21 is then fixed to the multidirectional base 29. A pair of opposing portions 30A, 30B disposed to face the support member 21 with a predetermined distance therebetween in the horizontal direction, i.e., the X direction; opposing portions 30C and 30D disposed to face the support member 21 with a predetermined distance therebetween in the Y direction, i.e., the vertical direction; and an opposing portion 30E disposed to face the support member 21 with a predetermined distance therebetween in the Z direction, i.e., the front-rear horizontal direction. On the other hand, in the support member 21, facing portions 21A to 21E are formed at positions facing the facing portions 30A to 30E of the multidirectional base 29, respectively.
Between the facing portions 21A, 21B of the support member 21 and a pair of facing portions 30A, 30B disposed opposite thereto at a predetermined distance in the X-direction, i.e., the horizontal direction, there are provided horizontal direction vibration-proof members 31A, 31B displaced in the thickness direction of the X-direction, respectively, and X-direction horizontal support bolts 32A, 32B having the same configuration as that described above are inserted from the opposite side to the facing portions 30A, 30B, and the distal end screw portions are screwed into the facing portions 21A, 21B.
Further, a vertical direction vibration-proof member 31C that is displaced in the thickness direction of the Y direction is provided between the facing portion 21C of the support member 21 and the facing portion 30C that is disposed facing the facing portion with a predetermined distance in the Y direction, that is, in the vertical direction, and a Y direction vertical support bolt 32C having the same configuration as that described above is inserted from the opposite side to the facing portion 30C, and the distal end screw portion is screwed into the facing portion 21C.
Further, a vertical direction vibration-proof member 31D that is displaced in the thickness direction of the Y direction is provided between the facing portion 21D of the support member 21 and the facing portion 30D that is disposed facing the facing portion with a predetermined distance in the Y direction, that is, in the vertical direction, and a Y direction vertical support bolt 32D having the same configuration as that described above is inserted from the opposite side to the facing portion 21D, and the tip end screw portion is screwed into the facing portion 30D.
Further, a front-rear horizontal direction vibration-proof member 31E displaced in the thickness direction of the Z direction is provided between the facing portion 21E formed by the main body portion of the support member 21 and the facing portion 30E disposed to face the facing portion with a predetermined distance in the Z direction, that is, the front-rear horizontal direction, and a Z-direction horizontal support bolt 32E having the same structure as that described above is inserted from the opposite side to the facing portion 30E, and the tip thread portion is screwed to the facing portion 21E of the support member 21.
The left and right horizontal direction vibration isolating members 31A and 31B, the vertical direction vibration isolating member 31C, and the front and rear horizontal direction vibration isolating member 31E are displaced in the thickness direction in the same manner as the horizontal direction vibration isolating member 24 and the vertical direction vibration isolating member 26 in the previous embodiment, thereby exerting a vibration isolating effect.
With this configuration, although the multidirectional base 29 is directly fixed to the base 16 of the ventilation apparatus 10, the support member 21 of the lid member electromagnetic lock device 14 is supported by the multidirectional base 29 in a floating manner.
When vibration occurs due to the operation of the cover member electromagnetic lock device 14, the left and right horizontal direction vibration-proof members 31A and 31B that are displaced in the thickness direction of the X direction are provided between the opposing portions 21A and 21B of the support member 21 and the opposing portions 30A and 30B of the multidirectional base 29, respectively, so that the vibration in the X direction can be absorbed or suppressed by the displacement of the left and right horizontal direction vibration-proof members 31A and 31B.
Further, since the vertical vibration isolation member 31C that displaces in the thickness direction of the Y direction is provided between the opposing portion 21C of the support member 21 and the opposing portion 30C of the multidirectional base 29, the vibration in the Y direction can be absorbed or suppressed by the displacement of the vertical vibration isolation member 31C. Similarly, since the front-rear horizontal direction vibration isolating member 31E that displaces in the thickness direction of the Z direction is provided between the opposing portion 21E of the support member 21 and the opposing portion 30E of the multidirectional base 29, the vibration in the Z direction can be absorbed or suppressed by the displacement of the front-rear horizontal direction vibration isolating member 31E.
In the ventilator 10 side, particularly, when the cover member 11 is locked or unlocked by the cover member electromagnetic locking device 14, shock vibration occurs due to a sudden operation. Since the vibration at this time is transmitted to the inside of the car 1 as an impact sound, if a passenger is present in the car in an emergency where the power supply is stopped, the passenger feels uneasy due to the vibration or the impact sound.
However, even if an impact occurs on the ventilator 10 side, the impact is absorbed or suppressed by the displacement in the thickness direction thereof because the left and right horizontal direction vibration-proof members 31A and 31B that displace in the thickness direction in the X direction, the vertical direction vibration-proof member 31C that displaces in the thickness direction in the Y direction, and the front and rear horizontal direction vibration-proof member 31E that displaces in the thickness direction in the Z direction are provided between the base 16 and the support member 21 of the ventilator 10. Therefore, even if there is a passenger in the car in an emergency where the power supply is stopped, the passenger can be prevented from being further disturbed by the vibration or noise.
In the present embodiment, as in the embodiment shown in fig. 2, since the horizontal vibration isolation member 24 disposed between the base 16 and the mounting wall surface 28 so as to surround the ventilation opening and the vertical vibration isolation member 26 disposed at other positions are provided, the impact vibration generated when the lid member 11 is opened and closed by the lid member opening and closing drive device 12 can be suppressed. Alternatively, the above-described effects can be achieved even if the horizontal direction vibration isolation member 24 and the vertical direction vibration isolation member 26 are omitted from the structure of fig. 3.
According to fig. 3 and 6 of the present embodiment, since the front-rear horizontal direction vibration-isolating member 31E is provided between the main body of the multidirectional base 29 and the main body of the support member 21, it is possible to absorb or suppress vibration in the Z direction by displacement of the front-rear horizontal direction vibration-isolating member 31E without complicating the structure of the multidirectional base 29 and the support member 21. That is, by using the multidirectional base 29 having a plurality of opposing portions, the arrangement of the vibration isolating members can be concentrated to a simple configuration. Therefore, in a preferred use mode, the horizontal vibration isolation member 24 shown in fig. 2 and 3 can be omitted, and the structure can be simplified.
Example 3
Fig. 4 and 5 are a front view and a sectional view of an elevator apparatus according to other embodiment of the present invention. Fig. 4 is a view seen from M of fig. 1 in the direction of arrow 100. The two figures show the structure of the connection between the distribution chamber 9 and the ventilator 10. As shown in fig. 4, a horizontal vibration isolating member 24 surrounding an unillustrated ventilation opening and an airtight member 23 surrounding an outer peripheral portion of the horizontal vibration isolating member 24 are disposed in a portion of the diversion chamber 9 facing the ventilator 10, as in the previous embodiments. Further, between the base 16 and the support member 21 of the ventilator 10, as in the embodiment shown in fig. 3, left and right horizontal direction vibration-proof members 31A and 31B that displace in the thickness direction in the X direction, a vertical direction vibration-proof member 31C that displaces in the thickness direction in the Y direction, and a front and rear horizontal direction vibration-proof member 31E that displaces in the thickness direction in the Z direction are arranged, respectively.
3 in 3 the 3 present 3 embodiment 3, 3 as 3 is 3 apparent 3 from 3 fig. 35 3, 3 which 3 is 3 a 3 sectional 3 view 3 taken 3 along 3 line 3 a 3- 3 a 3 in 3 fig. 3 4 3, 3 a 3 lower 3 holder 3 35 3 is 3 formed 3 in 3 a 3 lower 3 portion 3 of 3 the 3 diversion 3 chamber 3 9 3 so 3 as 3 to 3 protrude 3 toward 3 the 3 ventilator 3 10 3. 3 The base 16 of the ventilator 10 is attached to the lower bracket 35. The base 16 includes a bent portion 16A mounted on the lower holder 35, a plate-like body portion 16B disposed on the front side of the diversion chamber 9, and a bent portion 16C positioned on the upper surface side of the diversion chamber 9.
Vertical vibration-proof members 26A and 26B are provided between the lower holder 35 and the bent portion 16A of the base 16 and between the upper surface of the diversion chamber 9 and the bent portion 16C of the base 16, respectively, so as to be displaceable in the vertical direction, which is the thickness direction thereof. A horizontal vibration isolation member 24 is provided between the body portion 16B of the base 16 and the mounting portion of the diversion chamber 9 so as to be displaceable in the thickness direction, i.e., in the horizontal direction.
A plurality of vertical support bolts 27A are arranged in the longitudinal direction between the lower bracket 35 and the bent portion 16A, and a screw portion formed at the tip of the vertical support bolt 27A inserted from the bent portion 16A side is screwed into the lower bracket 35. Further, the vertical support bolt 27B disposed between the upper surface of the diversion chamber 9 and the bent portion 16C and the plurality of horizontal support bolts 25 disposed between the front surface of the diversion chamber 9 and the main body portion 16B of the base 16 are also formed with a screw portion at the tip of the vertical support bolt 27A inserted from the base 16 side, and are screwed into the diversion chamber 9 side at the insertion side tip.
However, no screw portion is formed near the head portions of the vertical support bolt 27A and the horizontal support bolt 25, and the base 16 has a coupling structure that can move a certain amount in the horizontal direction and the vertical direction with a margin (play). That is, the base 16 into which the vertical support bolt 27A and the horizontal support bolt 25 are inserted has a coupling structure in which a gap G is formed so as to be movable by a certain amount in the horizontal direction and the vertical direction with respect to the support bolts 25 and 27A, and a play is provided. The base 16 is held so that the horizontal vibration isolation member 24 and the vertical vibration isolation members 26A and 26B disposed between the diversion chamber 9 sides can be displaced by a predetermined displacement amount in the thickness direction thereof by the gap G of the connection structure having the play.
Since the base 16 is supported by such a support structure, even if vibration is transmitted from the lid opening/closing drive device 12 and the lid electromagnetic locking device 14 to the base 16, the horizontal vibration isolation member 24 and the vertical vibration isolation members 26A and 26B can be displaced by a certain displacement amount in the thickness direction thereof to suppress the vibration.
Further, as in the previous embodiment, the left and right horizontal direction vibration-proof members 31A, 31B that are displaced in the thickness direction in the X direction, the vertical direction vibration-proof members 31C, 31D that are displaced in the thickness direction in the Y direction, and the front and rear horizontal direction vibration-proof member 31E that is displaced in the thickness direction in the Z direction can be arranged between the support member 21 and the multidirectional base 29 in a concentrated and simple configuration. Further, since the displacement in the thickness direction can absorb or suppress the vibration particularly at the time of operating the electromagnetic locking device 14 of the cover member, even if a passenger is present in the car in an emergency where the power supply is stopped, the passenger can be prevented from being uneasy due to the vibration or the impact sound.
in the present embodiment, since the vertical support bolt 27B is provided between the upper surface of the diversion chamber 9 and the bent portion 16C of the base 16, the lower bracket 35 formed on the diversion chamber 9 side and the vertical support bolt 27A disposed between the lower bracket 35 and the bent portion 16A of the base 16 can be omitted. In the above embodiments, the flow path for adjusting the amount of air sent into the car 1 by the blower 6 is configured to have the diversion chamber 9 disposed in the ceiling portion of the car 1 and having the ventilation vent in the side surface portion thereof, and the ventilation device 10 is attached to the side wall surface of the diversion chamber 9 corresponding to the ventilation vent.
Therefore, compared to a structure in which the ventilation device is attached to the side surface of the car 1, the side portion of the car 1 can be simplified, interference with other various devices disposed in the hoistway is avoided, and the arrangement of the devices in the hoistway is not restricted. In addition, the design of the car 1 can be improved as compared with a configuration in which the ventilation device is disposed on the side surface of the car 1.
Further, since the ventilator 10 is mounted on the side wall surface of the branch chamber 9, the door member 11 for opening and closing the ventilation vent is always opened and closed in a substantially vertical state, and the opening and closing operation force can be reduced as compared with a case where the door member 11 is directly provided on the ceiling of the car 1 and is opened and closed in the vertical direction. This makes it possible to reduce the size of the opening/closing device for the door member 11 and to reduce the energy consumed by the opening/closing device. As a result, the door member 11 can be opened and closed efficiently.
In the preferred embodiment, the ventilation device 10 is disposed below the blower 6, so that the ventilation device can also serve as a flow path for air pressure control, and air convection due to a difference in height between the ventilation vent and the blower 6 is generated, thereby ventilating the interior of the car 1. Further, although the car 1 has a highly airtight structure, since a minute gap exists around the door 5 or the like, when the door member 11 is driven to open and the ventilation vent is opened, air convection can be generated between the ventilation vent and the minute gap existing in the car 1, and ventilation in the car 1 can be performed in the same manner.
However, in carrying out the present invention, the present invention is not limited to the case where the ventilator 10 is mounted on the branch chamber 9, and the present invention can be applied to a ventilator 10 in which a ventilation opening is formed in a ventilator mounting portion communicating with the inside of the car 1, the ventilation opening is closed by a cover member 11 in a normal state, and the ventilation opening is opened by opening the cover member 11 to perform ventilation in an emergency state where power supply is stopped. In addition, other configurations may be used for the lid member electromagnetic locking device 14 and the lid member opening/closing drive device 12.
As described above, in the elevator ventilator according to the present invention, the ventilator mounting portion 28 communicating with the inside of the car 1 is formed with the ventilation opening, the base 16 on which the cover member 11 is disposed supports the cover member electromagnetic locking device 14, and the horizontal vibration isolation member 24 or the vertical vibration isolation member 26 that is displaced in the thickness direction to provide vibration isolation is provided at the portion of the ventilator mounting portion 28 facing the base 16.
With such a configuration, even if an impact occurs on the ventilator 10 side, the horizontal direction vibration isolation member 24 or the vertical direction vibration isolation member 26 can absorb or suppress the impact by being displaced in the thickness direction thereof. Therefore, even if a passenger is present in the car in an emergency where power supply is stopped, the passenger can be prevented from being uneasy due to the vibration or impact sound.
In the elevator ventilator of the present invention, a ventilation opening is formed in a ventilator mounting portion 28 communicating with the inside of the car 1, the cover member electromagnetic locking device 14 is supported by the base 16 on which the cover member 11 is disposed via the support member 21, left and right horizontal direction vibration isolation members 31A and 31B displaceable in the thickness direction, i.e., in the left and right horizontal directions, vertical direction vibration isolation members 31C and 31D displaceable in the thickness direction, i.e., in the vertical direction, and a front and rear horizontal direction vibration isolation member 31E displaceable in the thickness direction, i.e., in the front and rear horizontal directions are disposed at a portion where the base 16 and the support member 21 face each other.
With this configuration, even when an impact occurs due to a sudden operation of the cover member electromagnetic locking device 14 of the ventilation apparatus 10, the left and right horizontal direction vibration isolation members 31A and 31B, the vertical direction vibration isolation members 31C and 31D, the front and rear horizontal direction vibration isolation member 31E, and the like are effectively displaced in the thickness direction thereof and absorbed or suppressed. Therefore, even if a passenger is present in the car in an emergency where power supply is stopped, the passenger can be prevented from being uneasy due to the vibration or impact sound. Further, by using the multidirectional base 29 having a plurality of opposing portions, the arrangement of the vibration isolating members can be concentrated to a simple configuration.
The present invention is not limited to the above-described embodiments, and various modifications are also possible. For example, the above-described embodiments are described in detail for easy understanding of the present invention, and are not limited to all configurations which have to be described. Further, a part of the structure of one embodiment may be replaced with the structure of another embodiment, and the structure of another embodiment may be added to the structure of one embodiment. In addition, some of the configurations of the embodiments may be added, deleted, or replaced with other configurations.
