Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a boarding / alighting assist device for eliminating a gap and a step between a vehicle entrance and a platform.

[0002]

2. Description of the Related Art Heretofore, since the existence of a gap between a train and a platform is dangerous, a device for solving the problem has been proposed. For example, JP-A-60-222360
Gazette, Japanese Patent Laid-Open No. 2-204160,
No. 170259, and the like. These devices use a cylinder or motor actuator to drive a step board that closes the gap, and store the step board in the storage position when passengers do not get on and off the train, while using the step position when passengers get on and off the train. Then, a step plate is made to appear to close the gap. The drive mechanisms of the step plates are different from each other, but in any case, the step plates close the gaps with the upper surface being horizontal at the use position.

[0003] However, there are often gaps as well as gaps between the platform and the vehicle floor. For this reason, in the related art, the gap is closed when the step plate is at the use position, but there is a disadvantage due to a step. Specifically, even at the latest station, the vehicle side is at least 50 mm higher than the platform surface, and it is expected that the level difference will be even greater at stations that have not been improved (bulged).

[0004] In addition, such a gap exists at least 50 mm even at a station having a straight track, and becomes larger at a station having a curved track. Since such gaps and steps exist, even if a wheelchair user tries to get on and off the train, he / she cannot get on and off by himself. Therefore, the wheelchair user is forced to get on and off the wheelchair by the station attendant and the attendant. For this reason, there is a problem that not only is it difficult for a wheelchair user to get on and off the train freely, but also the physical load on the attendant and the helper is large.

In order to solve such a problem, an apparatus for eliminating the above-mentioned step is disclosed in, for example, Japanese Patent Laid-Open No. 7-108.
926 or JP-A-7-108927. In these devices, the tipping edge is located at the track side edge of the platform corresponding to the entrance of the stopped vehicle, and is installed so that the upper surface coincides with the upper surface of the platform, and the tilting device arranged on the lower side A first slope plate that is tilted so that the leading edge rises, and a tip that is supported by the first slope plate and protruded by advance / retreat driving means so as to extend the first slope plate toward the leading end. A second slope plate having an edge approaching a platform-side edge of the floor of the entrance / exit is adopted.

[0006]

However, the above-described device requires two systems of driving means, a tilting device and an advancing / retracting driving device, so that the structure of the device is complicated and the cost is increased. is there. Further, as the structure becomes complicated, maintenance becomes complicated and the possibility of failure increases. Further, since a motor is used for each of the driving means in the above-described conventional apparatus, there is a possibility that normal operation may not be performed due to being wet with water. In particular, train platforms are not always roofed and are often exposed to rain. Therefore, it is desired to construct a system that is not easily affected by being wet with water.

[0007] Furthermore, in recent years, there has been a strong demand for barrier-free in places with particularly high publicity, and thus it is required to provide a getting-on / off assistance device at low cost.

[0008] The present invention has been made in view of such circumstances, and has as its object to improve the maintainability and durability by simplifying the structure and to reduce the manufacturing cost. Another object of the present invention is to provide a getting-on / off assistance device that can be operated quickly and reliably with a simple operation.

[0009]

According to a first aspect of the present invention, there is provided a boarding / alighting assisting device which is buried at an edge of a platform, and a plate-like body is formed so as to eliminate a gap and a step between a vehicle entrance and a platform during use. An getting-on / off assistance device for
A board buried at the edge of the platform, a first plate-shaped body rotatably supported at an end of the board opposite to the line, and slidably provided on a back surface of the first plate-shaped body. A second plate-like body extending from the end of the plate-like body on the track side to the vehicle entrance and retracting in a direction opposite to the track at the time of standby; a first engaging means provided on the second plate-like body; At least one rotating shaft, at least one arm engaged with the rotating shaft and rotating with the rotating shaft, and provided on the substrate, such that the rotating shaft is orthogonal to a direction in which the second plate-like body extends. , A bearing provided on the arm for contacting the back surface of the first plate-shaped member, and a bearing provided on the rotation center side of the arm relative to the contacting means, and engaged with the first engagement means. A second engaging means,
A driving means for supplying a driving force so that the action point reciprocates on a straight line substantially parallel to the direction in which the second plate-like body extends, and a cross section formed in a substantially convex shape, one end of which engages with the rotating shaft. The other end has at least one convex member including an action point, and the driving means supplies a driving force in a direction in which the second plate-shaped member extends in use, while the second plate-shaped member is in standby. A configuration for supplying the driving force in the backward direction is adopted.

As described above, the driving means is used on the track side during use.
That is, the driving force is supplied in the direction in which the second plate-like body extends. This driving force is transmitted to the convex member, and the convex member converts a linearly applied force into a rotational force. Thus, the rotating shaft that engages with the convex member rotates so as to raise the arm toward the line. When the arm stands up, the contact means provided on the arm raises the first plate-like body, and the second engagement means provided on the arm engages with the first engagement means to form the second plate-like body. Push your body toward the vehicle entrance. As a result, it is possible to shift from the standby state to the use state. As described above, the arm rotates only by the driving means supplying the driving force in a straight line, so that only one driving means for supplying the driving force in the direction of reciprocating on a straight line is required. Thus, the structure can be simplified, the maintainability and the durability can be improved, and the manufacturing cost can be reduced. Furthermore, since the operation can be shifted from the standby state to the use state in one operation, the operation by the operator is simplified, and the operation can be performed quickly and reliably.

According to a second aspect of the present invention, in the getting-on / off assistance device according to the first aspect, the arm has a first projection which comes into contact with the substrate at a position where the arm is inclined to the track side from the upright position during use, and a standby state. A second projection that contacts the substrate.

As described above, since the first projection abuts on the substrate at a position where the arm is inclined to the line side from the upright position during use, the arm is provided from above through the first plate-like body and the second plate-like body. Can withstand the load applied to. Therefore, the first plate-shaped body and the second plate-shaped body do not descend when the passenger is on the vehicle. Therefore, the passenger can get on and off the vehicle safely. In addition, the arm can be stopped at an appropriate position because the second protrusion comes into contact with the substrate during standby, and the load applied to the arm from above via the first and second plate members during standby can be reduced. Can resist. For this reason, even if a load is applied to the first plate during standby, the first plate does not sink into the platform.

According to a third aspect of the present invention, in the getting-on / off assistance device according to the first or second aspect, the abutting means and the second engaging means include a roller.

According to this configuration, the roller rotates when the contact means comes into contact with the first plate-shaped member, so that the operation of the arm to push up the first plate-shaped member can be performed smoothly. Further, since the roller rotates when the second engagement means pushes out the second plate-like body while engaging with the first engagement means,
The operation of pushing out the plate-like body can be performed smoothly.

According to a fourth aspect of the present invention, in the getting-on / off assist device according to any one of the first to third aspects, the first engagement means is a rail having a substantially U-shaped cross section and extending vertically. Take the configuration.

Thus, when the first plate-like body and the second plate-like body are put on the arm, the second engaging means rides on the rail, so that the first plate-like body and the second plate-like body are placed on the arm. The second engagement means can be engaged with the first engagement means only by putting on. When the second engaging means includes a roller, the roller rotates on the rail, so that the second engaging means smoothly pushes out the second plate-like body while engaging with the first engaging means. Can be performed.

According to a fifth aspect of the present invention, in the getting on / off assisting device according to any one of the first to fourth aspects, the driving means is an air cylinder.

Thus, the point of action at the tip of the cylinder can be reciprocated in a straight line by the pressure of air, and the arm can be rotated via the convex member. Therefore, a trouble due to water occurs as in the case of using a motor. Fear is gone.
When a motor is used as the driving means, it is necessary to electrically control the amount of rotation of the arm, and a circuit for this purpose is required, which complicates the device configuration. Therefore, a circuit for controlling the rotation amount of the arm is not required, and the configuration of the device can be simplified. Furthermore, air cylinders are less expensive than motors and actuators. As a result, the durability of the getting-on / off assistance device can be enhanced, and a proper operation can always be performed even on a platform exposed to rain, and at the same time, the cost can be reduced.

According to a sixth aspect of the present invention, in the getting-on / off assistance device according to any one of the first to fifth aspects, the second plate-shaped body further includes an insulating buffer means at a tip end on the vehicle side. Take.

With this configuration, even if the second plate-shaped body extending to the vehicle entrance is in contact with the vehicle body, the insulating buffer means reduces the impact, thereby preventing the vehicle body from being damaged. be able to. Further, by providing the buffer means in this way, it is possible to enhance safety for humans. In addition, since it has insulating properties, it is not affected electrically.

According to a seventh aspect of the present invention, in the getting-on / off assist device according to any one of the first to sixth aspects, the length in the width direction of the first plate-like body is equivalent to one tile block of the platform. The configuration is substantially the same as the length.

As described above, since the length in the width direction of the first plate-like body is substantially the same as the length of one tile block of the platform, when the getting-on / off assist device according to the present invention is installed on the platform, The tile block at the installation location can be peeled off, and the boarding / alighting assist device can be buried in the removed area in a good format. As a result, workability is improved, and it is possible to avoid the occurrence of irregularities around the getting-on / off assist device after the installation, and to maintain a good appearance.

According to an eighth aspect of the present invention, in the getting-on / off assistance device according to any one of the first to seventh aspects, at least one of a water-repellent treatment and a non-slip treatment is applied to a surface of the first plate-shaped body. Take the configuration that has been.

[0024] Thus, it is possible to prevent a passenger passing on the getting-on / off assistance device from slipping on the foot or slipping on the wheel of the wheelchair.

According to a ninth aspect of the present invention, in the getting-on / off assisting device according to any one of the first to eighth aspects, the substrate further includes a support means for supporting the first plate-shaped body during standby. .

With this configuration, even when a load is applied to the first plate-shaped body during standby, the load can be resisted. For this reason, even if a load is applied to the first plate during standby, the first plate does not sink into the platform.

According to a tenth aspect of the present invention, in the getting-on / off assistance device according to any one of the first to ninth aspects, the rotating shaft has a rectangular cross section.

This makes it easy to machine the rotating shaft,
It is possible to reduce costs and improve productivity. In other words, when the cross section of the rotating shaft is, for example, a circular shape, precise metalworking technology is required, which requires steps and time, resulting in an increase in cost. If it is rectangular, the sides are flat,
Processing is easy and does not require much construction time. As a result, costs can be reduced. Further, since the cross section of the rotating shaft is rectangular, the convex member and the rotating shaft can be easily engaged with each other by forming the portion of the convex member that engages with the rotating shaft into a U-shape. Become.

[0029]

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each of the drawings, the same elements are denoted by the same reference numerals, and redundant description will be omitted. Also, the dimensional ratios in the drawings do not always match those described.

FIG. 1 is a plan view of an getting-on / off assistance device according to an embodiment of the present invention. FIG. 2A is a cross-sectional view taken along line AA in FIG. 2) is a cross-sectional view taken along line BB in FIG. FIG. 1 shows an example in which two getting-on / off assistance devices according to the present embodiment are connected. The boarding / alighting assistance device 1 includes a substrate 2 installed on a base (not shown) embedded at an edge of the platform, and a first slope as a first plate-like body rotatably supported by the substrate 2 by a shaft 3. Plate 4 and substrate 2 of first slope plate 4
And a second slope plate 5 as a second plate-shaped body slidably provided on a surface facing the first slope plate. Substrate 2
In the standby state, the first slope plate 4 is installed at the edge of the platform such that the position of the upper surface of the first slope plate 4 substantially matches the surface of the platform.

The first slope plate 4 is connected to the substrate 2 by the shaft 3.
, And in a standby state, it is substantially horizontal and covers the substrate 2. At this time, the first slope plate 4
The height of the uppermost surface 4a substantially corresponds to the height of the platform surface. In use, the first slope plate 4 is
It is pushed up by an arm to be described later and rotates leftward in FIG. Thereby, as shown by a dotted line in FIG. 2, the line side end 4b rises.

The length of the first slope plate 4 in the width direction is substantially the same as the length of one tile block of the platform. As described above, since the length in the width direction of the first slope plate 4 is substantially the same as the length of one tile block of the platform, when the getting-on / off assist device according to the present invention is installed on the platform, The tile block can be peeled off, and the getting-on / off assistance device can be buried in the removed portion in a good shape. As a result, workability is improved, and it is possible to avoid the occurrence of irregularities around the getting-on / off assist device after the installation, and to maintain a good appearance.

The uppermost surface 4a of the first slope plate 4 is subjected to at least one of a water-repellent treatment and a non-slip treatment. Thus, it is possible to prevent a passenger passing on the getting-on / off assistance device from slipping on a foot or a wheel of a wheelchair.

The back surface 4c of the first slope plate 4, ie,
On the surface of the first slope plate 4 facing the substrate 2, a second slope plate 5 is provided so as to be freely slidable in the left-right direction in FIG.

FIG. 5 is an exploded perspective view of the first slope plate 4 and the second slope plate 5. As shown in FIG. 5, the second slope plate 5 is stored on the lower surface of the first slope plate 4 at the time of standby, and the first slope plate 5 is used at the time of use as shown by a dotted line in FIG.
The slope plate 4 rises and extends from the line side end 4b of the first slope plate 4. That is, the second slope plate 5
Functions to extend the length of the first slope plate 4.

It is also possible to adopt a configuration in which an insulating buffer means such as rubber or urethane is provided at the end of the second slope plate 5 on the vehicle side. Thereby, even if the second slope plate 5 extended to the vehicle entrance is in contact with the vehicle body,
Since the shock absorbing means reduces the impact, it is possible to prevent the vehicle body from being damaged. Further, by providing the buffer means in this way, it is possible to enhance safety for humans. In addition, since it has insulating properties, it is not affected electrically.

The back surface 5a of the second slope plate 5, that is,
Rails 6 as first engagement means are provided at both ends in the width direction of the surface of the second slope plate 5 facing the substrate 2. The rail 6 has a substantially U-shaped cross section and is formed to extend in the up-down direction, and engages with a metal roller as second engagement means described later.

Further, as shown in FIG. 1, the substrate 2 is provided with an air cylinder 7 for supplying a driving force such that the tip 7a including the point of action reciprocates on a straight line by compressed air. Further, it includes a bearing 8 fixed on the substrate 2 and a rotating shaft 9 supported by the bearing 8 and provided in parallel with the width direction of the substrate 2. The rotating shaft 9 includes an arm 10 that rotates with the rotating shaft 9 and a convex member 11 that engages with the rotating shaft 9. As shown in FIG. 1, a pair of bearings 8 supports one rotary shaft 9, and a drive mechanism provided with one arm 10 and one convex member 11 on the rotary shaft connects the air cylinder 7 with a wire. Two symmetry axes are provided so as to face each other. The two convex members 11 are connected by a drive shaft 12. The front end 7 a of the air cylinder 7 is engaged with the center of the drive shaft 12.

The substrate 2 is provided with support means 13 such as rubber, which has a buffering action. The support means 13 supports the first plate-shaped body 4 during standby.

Thus, even when a load is applied to the first plate-shaped body 4 during standby, it is possible to resist the load. For this reason, even if a load is applied to the first plate-shaped member 4 during standby, the first plate-shaped member 4 does not sink into the platform.

The air cylinder 7 is connected to an air compressor (not shown) via a hose (not shown). The air cylinder 7 receives a supply of compressed air from the air compressor, expands and contracts by a predetermined amount of expansion and contraction, and supplies a driving force so that the distal end portion 7a reciprocates on a straight line. Since the distal end portion 7a is engaged with the drive shaft 12,
The driving force of the air cylinder 7 is transmitted to the convex member 11. When the convex member 11 rotates about the rotation shaft 9, the arm 10 also rotates accordingly.

As described above, the operating point at the cylinder tip 7a is reciprocated on the straight line by the pressure of the air, and the convex member 11
Since the arm 10 can be rotated through the motor, there is no possibility that a trouble caused by water occurs when the motor is used. When a motor is used as the driving means, it is necessary to electrically control the amount of rotation of the arm 10 and a circuit for this purpose is required, which complicates the device configuration. Because it is determined, a circuit for controlling the rotation amount of the arm 10 is not required,
The apparatus configuration can be simplified. Further, the air cylinder 7 is less expensive than a motor or an actuator. As a result, the durability of the getting-on / off assistance device can be enhanced, and a proper operation can always be performed even on a platform exposed to rain, and at the same time, the cost can be reduced.

The rotating shaft 9 has a rectangular cross section. As described above, by forming the cross section of the rotating shaft 9 into a rectangular shape, the working of the rotating shaft 9 is facilitated, and it is possible to reduce costs and improve productivity. That is,
When the cross section of the rotating shaft 9 is, for example, circular, it requires a precise metal working technique, and thus requires a process and time,
As a result, the cost is increased, but when the cross section of the rotating shaft 9 is rectangular, the processing is easy and the construction time is not required because the side surface is flat. As a result, costs can be reduced. In addition, since the cross section of the rotating shaft 9 is rectangular, the portion of the convex member 11 that engages with the rotating shaft 9 is formed in a U-shape so that the convex member 11 and the rotating shaft 9 can be easily engaged. It is possible to do.

Next, the arm 10 will be described. FIG.
FIG. 4 is a perspective view illustrating a state where the first slope plate 4 is removed from the getting-on / off assist device in a standby state, and FIG. 4 is a perspective view illustrating a state where the first slope plate 4 is removed from the getting-on / off assist device in a use state. FIG.

The arms 10 are provided one by one on the rotating shaft 9 and rotate together with the rotating shaft 9. Arm 1
0 is inclined to the opposite side of the line with respect to the rotating shaft 9 during standby. In addition, a metal roller 10b that comes into contact with the back surface 4c of the first slope plate 4 is provided at the end 10a of the arm 10 as contact means. When the rotating shaft 9 rotates rightward in FIG. 2 during use, the arm 10 rotates so as to stand upright in FIG. As a result, the metal roller 10b provided at the end 10a of the arm 10 pushes up the first slope plate 4 from below, so that the first slope plate 4 rotates around the shaft 3 to the left in the figure. As a result, the line end 4b of the first slope plate 4 rises.

The arm 10 is provided with a metal roller 10 as a second engaging means at a position closer to the center of rotation than the end 10a.
c is provided. This metal roller 10c is
It engages with a rail 6 provided on the slope plate 5. Therefore, when the rotating shaft 9 rotates rightward in FIG. 2 during use,
The metal roller 10c provided on the arm 10 presses the rail 6 toward the track while the arm 10 rotates so as to stand rightward in FIG. Thus, the second slope plate 5 moves rightward in FIG. 2 and extends from the line side end 4b of the first slope plate 4.

As described above, the metal roller 10b for pushing up the first slope plate 4 and the metal roller 10c for extending the second slope plate 5 are provided on the arm 10, so that by rotating the arm 10, one operation can be performed. The first slope plate 4 can be pushed up and the second slope plate 5 can be extended.

When the metal roller 10b rotates when the metal roller 10b comes into contact with the first slope plate 4, the arm 10
Can smoothly perform the operation of pushing up the first slope plate 4. Further, since the roller rotates when the metal roller 10c pushes the second slope plate 5 while engaging with the rail 6, the operation of pushing the second slope plate 5 can be performed smoothly.

The rail 6 as the first engaging means is
The cross section is approximately U-shaped and extends in the vertical direction. When the first slope plate 4 and the second slope plate 5 are put on the arm 10, the metal roller 10 c rides on the rail 6. The metal roller 10c can be engaged with the rail 6 only by putting the two-slope plate 5 on the arm 10.

In this embodiment, the rail 6 having a substantially U-shaped cross section and extending in the vertical direction has been described as an example of the first engaging means, but the present invention is not limited to this. That is, as the first engagement means, another mode,
For example, the cross-section of the rail may be L-shaped, or the cross-section may be half-moon-shaped, and other shapes are also possible. Also, as the second engagement means, a metal roller 1
Although 0c has been described as an example, the present invention is not limited to this. That is, it is also possible to use another form, for example, a cam follower or a pin, as the second engagement means. In addition, the durability of the metal roller 10
Although b and 10c are used, urethane rollers or the like may be used.

The arm 10 is provided with a first projection 30 which comes into contact with the substrate 2 during use. The arm 10 rotates so as to stand in the right direction in FIG. 2 during use. In order to determine the positions of the first slope plate 4 and the second slope plate 5,
It is necessary to stop at a position slightly above the upright position on the rotating orbit. For this reason, the arm 10 is provided with a first protrusion 30 that comes into contact with the substrate 2 during use.

As described above, when the arm 10 is tilted toward the track from the upright position during use, the first protrusion 30 is
Therefore, it is possible to resist a load applied to the arm from above through the first plate-shaped member 4 and the second plate-shaped member 5. Therefore, the first plate-shaped member 4 and the second plate-shaped member 5 do not descend when a passenger is on the vehicle. Therefore, the passenger can get on and off the vehicle safely.

Further, the substrate 10 is mounted on the arm 10 during standby.
And a second protrusion 31 that is in contact with the second protrusion 31. Since the second protrusion 31 comes into contact with the substrate at the time of standby, the arm can be stopped at an appropriate position, and at the time of standby, via the first plate-like body 4 and the second plate-like body 5. It can resist the load applied to the arm from above. For this reason, even if a load is applied to the first plate-shaped member 4 during standby, the first plate-shaped member 4 does not sink into the platform.

Next, the operation of the getting-on / off assist device according to one embodiment of the present invention configured as described above will be described.

FIG. 6 is a perspective view of the getting-on / off assist device 1.
As shown in FIG. 6, the first slope plate 4 covers the entire other components including the substrate 2 during standby. The first slope plate 4 is substantially horizontal, and forms the same plane as the surface of the platform. For this reason, the getting-on / off assistance device 1 does not obstruct the passage of passengers during standby. Further, since the second slope plate 5 is stored on the lower surface of the first slope plate 4 during standby, it does not protrude from the edge of the platform, and therefore does not obstruct the passage of the train.

FIG. 7 is a diagram showing a use state of the getting-on / off assistance device according to the present embodiment. When the operator presses one switch (not shown), the first slope plate 4 rises, and the second slope plate 5 extends from the track side end 4b. As described above, since the air cylinder 7 that generates a strong force is used as the driving force, the time required for transition from the standby state to the use state is about one second. Since the first slope plate 4 rises and the second slope plate 5 extends to the entrance / exit of the train, gaps and steps existing between the entrance / exit of the train and the platform are eliminated.

FIG. 8 is a perspective view showing a standby state when two getting-on / off assistance devices 1 according to the present embodiment are connected.
Here, a vinyl sheet 80 is provided so as to extend over the entire two second slope plates 1. In the center of the vinyl sheet 80, a symbol of a wheelchair user is shown. Thus, when the getting-on / off assist device 1 is installed on the platform, it is possible for the user to easily find the place where the getting-on / off assist device 1 is installed. Further, by selecting the color of the vinyl sheet 80 so as to be conspicuous on the platform, the getting-on / off assist device 1 can be more easily found.

FIG. 9 is a perspective view showing a use state when two getting-on / off assist devices 1 according to the present embodiment are connected.
In the use state, each first slope plate 1 and each second slope plate 5 operate simultaneously. By connecting a plurality of the getting-on / off assistance devices 1 in this manner, the operating range can be expanded.

FIGS. 10A and 10B are diagrams showing switches for operating the getting-on / off assist device 1 according to the present embodiment. The switch 100 can transmit a signal to the getting-on / off assistance device 1 by wire, wirelessly, or infrared rays. In the present embodiment, the wireless switch does not require any work such as wiring installation on the platform, and the wired switch may cause mischief on the platform. For example. FIG.

Thus, if the C button 104 is pressed again while the power is on once, the power can be turned off. If the C button 104 has not been pressed in step S3, it is determined whether the B button 103 has been pressed (step S5). At this stage, no operation takes place even if the B button 103 is pressed, since it is in the standby state. That is, in step S5, B
If the button 103 has been pressed, the process returns to step S5.

If the B button 103 has not been pressed in step S5, it is determined whether the A button 102 has been pressed (step S6). A button 102
If is not pressed, the process returns to step S5. When the A button 102 is pressed in step S6, the getting-on / off assist device 1 operates (step S7).
That is, compressed air is supplied from the air compressor to the air cylinder 7, and the air cylinder 7 extends. The convex member 11, the rotating shaft 9, and the arm 10 rotate by receiving the driving force of the air cylinder 7. The rotation of the arm 10 raises the first slope plate 4 and extends the second slope plate 5.
At this time, the LED lamp 101 lights up in red. Thereby, the operator can easily recognize that the getting-on / off assistance device 1 is in use.

Next, in the use state, the A button 102
It is determined whether or not has been pressed (step S8). If not, the process returns to step S8. For this reason,
No operation occurs even if the A button 102 is pressed in the use state. Further, it is determined whether or not the C button 104 has been pressed (step S9), and if not, the process returns to step S8. Therefore, no operation occurs even if the A button 102 is pressed in the use state.

Next, it is determined whether or not the B button 103 has been pressed (step S10). If the B button 103 has not been pressed, the process proceeds to step S8 again. However, if the B button 103 has been pressed, the getting-on / off assistance device 1 operates (step S11). That is, compressed air is supplied from the air compressor in a direction opposite to that in use, and the air cylinder 7 contracts. As a result, the convex member 11, the rotating shaft 9, and the arm 10 rotate in the opposite direction to that in use, the second plate-like body 5 retreats, and the first plate-like body 4 descends, and enters a standby state. . Next, in a standby state, the power is automatically turned off, the LED lamp 101 is turned off, and the process ends (step S12).

As described above, when the B button 103 is pressed in the use state, the state shifts to the standby state and the power is turned off, so that forgetting to turn off the power can be avoided.
