On the other hand, when such a fall prevention device or the like is installed on the platform, it is necessary to carry out using a non-arrival time zone (for example, from midnight to dawn) when the train is not departed. In this case, it is necessary to restore the platform to the original state where the platform can be elevated until the train starts and arrives.

However, in this prior art, it is difficult to employ the apparatus when there is no space for installing the apparatus under the platform. Moreover, since it has a horizontal moving apparatus for moving a step member substantially horizontally, and the elevating apparatus for elevating a step member, the structure of an apparatus is complicated and a cost rises. In addition, since the step member needs to continuously perform two different operations (horizontal direction operation and lifting operation), it is difficult to perform the operation of the step member in a short time, and if the step member does not perform the operation in a short time, There was a problem that it would be a problem to reduce the time required.

Thus, in the application for Japanese Patent Application No. 2000-162810 filed previously, the present applicant can install the device regardless of whether or not there is a space for installation below the platform, and with a simple configuration, the cost can be reduced, and further, the fall We proposed the fall prevention device of the platform that can perform the forward and backward movement of the prevention member in a short time and can be adopted in any platform of the landing situation. Also, when the platform is constructed using the non-departure time zone, Until the start of the installation, the platform can be easily restored to its original state that can be elevated, and proposed a method of installing a platform fall prevention device that can be adopted in any platform of the landing situation.

Next, the operation of the present invention will be described.

The end edge 12 of the platform 10 has a limit position protruding toward the track in relation to the train for safety, and the end edge 12 of the platform 10 and the end edge 12 of the platform 10 are fixed. There is surely a space S1 between the locations where the train most approaches. The train does not contact the protruding from the platform 10 side within this space S1.

Therefore, the limit position at which the fall preventing member 21 protrudes toward the track is also determined. The fall prevention member 21 moves in and out in the substantially horizontal direction to the immersion position and the protrusion position by the drive mechanism 30. The fall preventing member 21 is accommodated in the receiving portion 15 in the immersed position in the case of non-elevation, and does not protrude toward the track from the edge 12 of the platform 10. , The space S1 between the train and the edge 12 of the platform 10 is blocked.

That is, since the fall prevention member 21 only performs the simple operation of piercing in the substantially horizontal direction, the fall prevention member 21 can be operated in a short time, and the time required for lifting can be shortened. . Since the fall prevention member 21 only needs to be driven in a substantially horizontal direction, the drive mechanism 30 can be easily configured.

When the space S1 to be blocked by the fall preventing member 21 becomes long, the fall preventing member 21 also needs to be long, and, for example, when the fall preventing member 21 is integrally formed, the fall preventing member ( Since 21) becomes large and heavy, handling thereof becomes difficult and assembly workability deteriorates.

Thus, the fall prevention member is composed of two or more plates 210, and the two or more plates 210 are disposed along the end edges 12 of the platform 10 to be engaged or connected with each other. Thereby, each plate 210 becomes short and light, and at the time of assembling the fall prevention apparatus 20, handling of each plate 210 becomes easy and assembly workability improves.

In addition, in assembling the plate 210 and the guide mechanism 40 of the fall prevention apparatus 20, for example, the guide mechanism 40 is provided in the accommodating part 15 of the platform with the plate 210. Due to the surface accuracy of the mounting surface of the storage portion 15 and the product precision of the guide mechanism 40 or the plate 210, a height difference occurs between the guide members 48 and 49 of the guide mechanism 40. Alternatively, because the guide members 48 and 49 are inclined with respect to the horizontal plane, a height difference occurs between the plates 210 or the plates 210 are inclined, but adjacent to each plate 210. Since they are connected to each other, the connected portions can absorb the height difference and the inclination of each plate 210, so that each guide member 48, 49 can guide each plate 210 smoothly. .

As described above, in the case where the fall preventing member 21 is formed by engaging or connecting adjacent ones of the two or more plates 210 to each other, the driving mechanism 30 for driving the fall preventing member 21 is two. It is sufficient to drive at least one of the above-mentioned plates 210 so that they can be sunk. As a result, the other plate 210 is haunted by the driving plate 210.

In the fall preventing device 20, the plate 210 and the guide members 48 and 49 are used as one pair, and the plate 210 and the guide members 48 and 49 are configured independently of each other. As the two sets, it is not limited to the two parts of the plate 210 and the guide members 48 and 49, but may include other related parts of the fall prevention device 20. And the fall prevention unit 200 may be configured, and the fall prevention device 20 may be configured by two or more of the fall prevention unit 200.

The fall prevention unit 200 is assembled in advance, and a plurality of assembled fall prevention units 200 are brought into the platform 10, and each drop prevention unit 200 is placed along the side edge of the platform 10. When the arrangement is made, and the plates 210 of the respective fall prevention units 200 are connected to each other, the fall prevention device 20 can be easily installed by the platform 10, thereby improving workability.

As described above, in the two or more anti-dropping units 200 installed in the receiving portion 15 of the platform, each of the anti-dropping units 200 due to the surface accuracy of the mounting surface of the storing portion 15 or the product precision of the anti-dropping unit 200 is Since the height difference occurs between the fall prevention units 200, the height difference occurs between each plate 210, each plate 210 is inclined, but adjacent ones of each plate 210 are connected to each other. Therefore, the height difference and the inclination of each plate 210 can be absorbed by the connected part.

In addition, even in the fall prevention apparatus which consists of such a some fall prevention unit 210, it is good to drive the plate 210 of the at least 1 fall prevention unit 200 by the drive mechanism 30. FIG.

The drive mechanism 30 is for electric and manual use. For example, although the electric drive mechanism 30 is normally used, when the electric drive is broken, the manual drive mechanism 30 is used.

The manual drive mechanism 30 includes a pinion 32 and a rack member 35. For example, by rotating the pinion 32 directly or indirectly by turning the handle H1 using the handle H1 or the like, the rack member 35 engaged with the pinion 32 is linearly moved. You will fall out or go inside. Accordingly, the plate 210 to which the rack member 35 is fixed is moved in and out.

In order to install the fall prevention apparatus 20, it is performed as follows.

First, the accommodating part 15 is formed in the upper surface 14 of the edge part 13 of the platform 10 concave. For example, the upper surface 14 of the platform 10 is cut off by a predetermined thickness to form the accommodating part 15.

Next, the fall prevention device 20 is inserted in the accommodating part 15 and fixed to the platform 10 side. The fall arrest apparatus 20 may be assembled to the accommodating part 15, or may be assembled before and after the insertion. In addition, when the completed fall prevention device 20 is brought into the construction site, workability is good, and the time required for installation work of the fall prevention device 20 is shortened.

After the fall preventing device 20 is inserted into the housing 15, the housing 15 is covered with the ceiling member 50 from above, so that the housing 15 can be easily hidden, and further, the fall prevention is prevented. The member 21 can also be protected.

The ceiling member 50 constitutes the upper surface 14 of the edge portion 13 of the platform 10 only by covering the housing 15 with the ceiling member 50, and thus elevating the platform 10. It is possible to easily restore the original state as much as possible. Even if the installation work is not completed within the non-arrival time zone, the ceiling member 50 covers the receiving portion 15 formed concave on the platform 10 until the next non-arrival time zone for the next installation work. In the next installation work, the ceiling member 50 is simply removed, and the installation work becomes very easy.

On the other hand, even if the ceiling member 50 does not constitute the upper surface 14 of the end edge portion 13 of the platform 10, the ceiling member 50 is the upper surface 14 of the end edge portion 13 of the platform 10. In the same way as to be embedded, the original unit which can lift the platform 10 can be lifted by simply covering the housing 15 with the ceiling member 50 and covering the mat member on the ceiling member 50. It can be easily restored to a state, and installation work becomes very easy similarly. This ceiling member 50 is finally embedded with the surface material of the platform 10.

The ceiling member 50 constitutes the main body of the fall prevention device 20 or the main body of the fall prevention unit 200 as the ceiling member 50 as a component of the fall prevention device 20 or the fall prevention unit 200. By assembling in advance, it is possible to further reduce the time required for installation work.

After installation of this apparatus, there may be a non-lubricating type that does not supply lubricant to the drive mechanism 30 including the guide mechanism 40 or an oil supply type that regularly supplies lubricant.

In the oil supply type, the lubricating oil is supplied from the supply source inlet 81 to a plurality of predetermined portions of the drive mechanism 30 including the guide mechanism 40. At this time, the lubrication hole 82 penetrates from the upper surface 14 of the end portion 13 of the platform 10 toward the supply source inlet 81 or near the supply inlet 81 to the housing 15. Thus, for example, the lid member blocking the oil supply hole 82 at the time of non-lubrication is removed at the time of oil supply, and connected to the supply source inlet 81 through the oil supply pipe to the open oil supply hole 82, Later, the oil supply pipe is removed from the supply source inlet 81, and the oil supply work hole 82 is removed from the oil supply hole 82, and then the oil supply operation hole 82 is blocked by the cover member. It is possible to refuel.

The fall preventing member 21 is used by protruding from the immersion position to the protruding position as needed, such as at the time of lifting and lowering. The above space is set to be formed.

However, in some situations, when the train enters, there is a situation where the fall preventing member 21 protrudes in the protruding position, and the train entering and coming in contact with the fall preventing member 21 in the protruding position. It cannot be said that it does not occur, and if such a situation occurs and the load preventing member 21 in the protruding position is loaded with a predetermined amount or more in the immersion direction, the fall preventing member 21 is configured to immerse. The mutual impact of the fall preventing member 21 is not small, and some countermeasures must be taken to further mitigate the mutual impact.

Therefore, as a countermeasure, the forced retraction mechanism 100 is arranged at least on both sides of the protruding position.

In any situation, when the train entering the fall prevention member 21 in the protruding position comes into contact, and receives an external force from the train, the forced retraction mechanism 100 located on the side where the train enters rather than the fall prevention member 21. ) Receives an external force from the train in place of the fall prevention member 21.

The forced retraction mechanism 100 receiving the external force from the train transmits the external force to the fall prevention member 21. As a result, the fall preventing member 21 is forcibly immersed in the protruding position. That is, since the train only contacts the forced retraction mechanism 100 and does not contact the fall preventing member 21, the mutual impact of the train and the fall preventing member 21 can be alleviated.

In addition, the forced retraction mechanism 100 receives an external force from the train in place of the fall prevention member 21, forcibly immersing the fall prevention member 21, but after immersing the fall prevention member 21 again. When protruding to the protruding position, in order to prepare the forced retraction mechanism 100 for the next contact with the train, the forced retraction mechanism 100 may be successively operated on the fall preventing member 21 protruding to the protruding position.

In addition, the forced retraction mechanism 100 has an input member 110 and at least one or more relay members 120 which are arranged on at least two sides of the fall prevention member 21 to enter the train.

That is, the input member 110 in the first position extends to at least the same position with respect to the protruding position of the fall preventing member 21 toward the track from the end edge 12 side of the platform 10.

Therefore, if the entering train does not contact the input member 110, it does not contact the fall prevention member 21. In some situations, when the entering train contacts the input member 110, with an external force from the train, the input member 110 is displaced from the first position to the second position, so that the end edge of the platform 10 on the track side ( 12). In this case, one or more relay members 120 transmit the external force received by the input member 110 to the fall prevention member 21. As a result, the fall preventing member 21 is forcibly immersed in the protruding position.

Thus, instead of the fall prevention member 21, the input member 110 which receives an external force from a train is arrange | positioned so that it can rock, for example in a 1st position and a 2nd position. When an external force is applied to the input member 110, the proximal end of the input member 110 rotates, and a direction in which one or more relay members 120 immerses the fall preventing member 21 in the direction of the rotating direction. Converted to a force of, to be transmitted to the fall prevention member (21).

As described above, the input member 110 receives external force from the train and enters the second position from the first position in place of the fall prevention member 21, but falls in the immersed state after contact with the train. When the protruding member 21 protrudes back to the protruding position, the input member 110 is continuously operated so as to extend from the second position to the first position, thereby preparing for contact with the expected train again. .

When the forced retraction mechanism 100 receives the external force from the entering train in place of the fall preventing member 21 in the protruding position, the forced retraction mechanism 100 transmits the external force to the fall preventing member 21, thereby preventing the fall member ( 21) forcibly immersable from the protruding position.

Further, in the present embodiment, the forced retraction mechanism 100 is configured to operate in succession to the fall preventing member 21 which protrudes into the protruding position after the immersion, and again, the fall preventing member (in the protruding position) is applied to the external force from the train. 21) to return to the acceptable state instead.

Specifically, the forced retraction mechanism 100 has an input member 110 disposed on at least a train entry side of both the fall preventing members 21 and one or more relay members 120.

The input member 110 has a first position extending from the end edge 12 side of the platform 10 toward the track to at least the same position with respect to the protruding position of the fall preventing member 21, and the end of the platform 10 at the track side. It is arranged to be displaceable to a second position entering towards the edge 12.

The one or more relay members 120 transmit the external force to the fall prevention member 21 when an external force that is displaced from the first position to the second position with respect to the input member 110 is caused by the entering train. The fall preventing member 21 is disposed so as to be forcibly immersed from the protruding position.

In addition, in this embodiment, the input member 110 is arrange | positioned so that it can rock at the 1st position shown by the solid line in FIG. 2, and the 2nd position shown by the virtual line in the figure. In addition, the input member 110 is successively operated by the fall preventing member 21 which protrudes into the protruding position after immersion, and is configured to swing and extend from the second position toward the first position.

That is, the input member 110 is formed in a bell crank shape, pivot-supported to the pivot support pin 112 on the base member 111 so as to be pivotable, and a roller 113 at the input end of the input member 110. Is supported, one end of the relay member 120 is connected to the output end 114 of the input member 110, and the other end of the relay member 120 is a fall preventing member 21 (in the embodiment, a guide member ( Side edge of the edge 220). In addition, a recess (not shown) is formed in the fall preventing member 21 to avoid interference with the input member 110 entering the second position.

The operation is explained next.

First, the operation of only the fall prevention device 20 will be described, and the action of the forced retraction mechanism 100 and the like will be described later.

In order to install the fall prevention device 20 at the end edge portion 13 of the platform 10, first, the receiving portion 15 is formed in the upper surface 14 of the end edge portion 13 of the platform 10. do. For example, the upper surface 14 of the platform 10 is cut off by a predetermined thickness to form the accommodating part 15.

Next, the fall prevention device 20 is inserted in the storage part 15. At this time, if the fall prevention unit 200 is assembled in advance and the fall prevention unit 200 is brought into the construction site, the workability is good and the time required for the installation work of the fall prevention device 20 is shortened. do. Moreover, since each fall prevention unit 200 becomes small and light, it is easy to handle each fall prevention unit 200 at the time of installation of the fall prevention unit 200, and installation workability improves.

The three drop prevention units 200 assembled beforehand are put side by side in one storage part 15, and each drop prevention unit 200 is placed on the bottom surface 16, which is an installation surface of the storage part 15. Install at a predetermined position. Next, the concave portion 212 of the plate 210 of the drop prevention unit 200 at both ends is inserted into the convex portion 211 of the plate 210 of the drop prevention unit 200 in the center, and a pin (not shown) is shown. Connect so that rotation is possible.

Thus, in the three fall prevention units 200 provided in the bottom face 16 of the accommodating part 15, each fall prevention unit (depending on the surface precision of the bottom face 16 of the accommodating part 15) ( Since the height difference occurs between the 200, the height difference occurs between each plate 210, each plate 210 is tilted, but because each divided plate 210 is connected to each other, by the connected portion The height difference and the inclination of each plate 210 can be absorbed, and the guide mechanism 40 can guide each plate 210 smoothly. Accordingly, there is no need to adjust the height between each falling prevention unit (200). This also makes it possible to shorten the time of installation work.

After that, if the housing part 15 is covered with the ceiling member 50 from above, the housing part 15 can be easily concealed and the fall prevention member 21 can be protected. What constitutes the main body frame 201 of the fall prevention unit 200 as the ceiling frame is that the ceiling member 50 assembles the ceiling member 50 as a component of the fall prevention unit 200 in advance. The time can be further reduced.

The ceiling member 50 constitutes the upper surface 14 of the edge portion 13 of the platform 10 only by covering the housing 15 with the ceiling member 50, and elevating the platform 10. It is possible to easily restore the original state as much as possible. Even if the installation work is not completed within the non-arrival time zone, the ceiling member 50 covers the receiving portion 15 formed concave on the platform 10 until the non-arrival time zone during the next installation work. It is only necessary to put it in place, and the next time the installation work is carried out, the ceiling member 50 only needs to be removed, so the installation work becomes very easy. In addition, the upper surface of the ceiling member 50 used as the upper surface 14 of the edge portion 13 of the platform 10 may be prevented from slipping.

On the other hand, even if the ceiling member 50 does not constitute the upper surface 14 of the end edge portion 13 of the platform 10, the ceiling member 50 is the upper surface 14 of the end edge portion 13 of the platform 10. In the same way as to be embedded, the original unit capable of elevating the platform 10 is simply covered by covering the housing portion 15 with the ceiling member 50 and covering the mat member on the ceiling member 50. It can be easily restored to a state, and installation work becomes very easy similarly. This ceiling member 50 is finally embedded with the surface material of the platform 10.

Next, the operation of the fall prevention device 20 will be described.

Before the train arrives at the platform 10, the fall prevention member 21 is accommodated in the receiving portion 15 at the immersed position and does not protrude toward the track from the edge 12 of the platform 10. In addition, the hatch PF is in a closed state, and the pair of lifting doors 70 protrude to the side of each door storage railing 61.

The start of the ascent is performed as follows. That is, when the train arrives at the platform 10 and the train stops, the electric motor 38 operates to rotate the screw member 37, and the nut member 36 moves forward to move the guide member 220 forward. Push it out. Accordingly, the guide member 220 is guided to the guide mechanism 40 and advanced, so that the plate 210 of the drop prevention unit 200 at both ends is mounted on the plate 210 of the drop prevention unit 200 in the center being driven. 3), the three plates 210 protrude together from the immersion position toward the line of the protruding position, thereby blocking the space S1.

Next, the elevating door 70 is driven in the immersion direction by a driving unit (not shown), immersed in the door storage railing 61, stored in the door storage railing 61, and dropped sideways in front of the passenger door of the train. The door PF is opened. The door of the train opens and the ascent starts.

End of lifting is performed as follows. That is, the lifting door 70 is driven in the protruding direction by a drive unit (not shown), protrudes from the door storage railing 61, and first places the lifting door PF closed. Next, the electric motor 38 rotates in reverse, the screw member 37 rotates, the nut member 36 is moved backward, and the guide member 220 is pushed backward. Accordingly, as the guide member 220 is guided to the guide mechanism 40 and retracts, the plate 210 of the drop preventing unit 200 at both ends is plated on the plate 210 of the drop preventing unit 200 in the center being driven. 3), the three plates 210 are immersed together from the protruding position into the immersive position and received in the accommodating portion 15. Next, the lift is completed with the door of the train closed.

When the fall preventing member 21 is immersed, for example, when the pressure detection switch installed in the fall preventing member 21 composed of three plates 210 senses a passenger, the fall preventing member 21 does not immerse the operation. In addition, the immersion operation is stopped to ensure safety.

In this way, the fall preventing member 21 only performs a single operation of bringing the immersion position and the protruding position in the substantially horizontal direction, and the sunken operation of the fall prevention member 21 is performed in a short time, so that It can save time.

Thus, although the electric drive mechanism 30 is normally used, for example, when the electric drive mechanism 30 is broken, the manual drive mechanism 30 is used.

In order to drive the fall prevention member 21 using the manual drive mechanism 30, the rotary shaft of the handle H1 is inserted into the pinion 32, for example, and connected to the pinion by the handle H1. When the on 32 is rotated, the pinion 32 pulls the rack member 35 forward, and the guide member 220 is guided to the guide mechanism 40 to move forward. Thereby, the plate 210 of the fall prevention unit 200 of the center is driven, and the plate 210 of the fall prevention unit 200 of both ends follows, and the three plates which comprise the fall prevention member 21 are followed. 210 together protrudes from the immersion position toward the line of the protruding position, thereby blocking the space S1.

On the other hand, when the pinion 32 is operated in reverse rotation by the handle H1, the rack member 35 is inserted backward, and the guide member 220 is guided to the guide mechanism 40 to retreat. Accordingly, the plate 210 of the center anti-drop unit 200 is driven, followed by the plate 210 of the anti-drop unit 200 at both ends, so that the three plates 210 immerse together from the protruding position. It is immersed in the position and is accommodated in the accommodating part 15.

Next, the oil supply operation | movement to the drive mechanism 30 containing the guide mechanism 40 is demonstrated.

After installation of this apparatus, lubricating oil is periodically supplied to a plurality of predetermined portions of the drive mechanism 30 including the guide mechanism 40 at the time of maintenance inspection.

First, in the case of non-lubrication, the cover member 83 blocks the lubrication work hole 82 drilled in the end edge portion 13 of the platform 10, and the cover member 83 is the end edge of the platform 10. It is continued smoothly with respect to the upper surface 14 of the part 13. Therefore, the oiling operation hole 82 or the cover member 83 is formed so as not to interfere with the normal use of the platform 10.

At the time of oil supply, the cover member 83 which blocks the oil supply hole 82 from the upper side is removed at the time of oil supply. At this time, the lubrication hole 82 penetrates from the upper surface 14 of the end edge portion 13 of the platform 10 toward the supply source inlet 81 or the vicinity of the source inlet 81 to the housing 15. Therefore, when the oil supply pipe is passed through the open oil supply hole 82, the oil supply pipe can be directly and easily connected to the supply source inlet 81.

After lubrication, the lubrication pipe is removed from the supply source inlet 81 and pulled out of the lubrication hole 82, and then the lubrication operation hole 82 is blocked by the cover member 83, and the lubrication operation is completed. The upper surface 14 of the edge portion 13 of the platform 10 returns to the original non-lubrication state.

Next, the operation of the forced retraction mechanism 100 will be described.

The fall prevention member 21 is used by protruding from the immersion position to the protruding position as needed, such as at the time of lifting and lowering. The space is set to be formed. Therefore, normally, there is no contact with the fall preventing member 21 at the protruding position of the incoming and outgoing train.

However, in some situations, when the train enters, the fall preventing member 21 is not immersed and is in a state of protruding at the protruding position so that the train entering the fall preventing member 21 at the protruding position contacts. When the external force from the train is received, the forced retraction mechanism 100 located on the side where the train enters rather than the fall prevention member 21 receives the external force from the train in place of the fall prevention member 21.

The forced retraction mechanism 100 receiving the external force from the train transmits the external force to the fall prevention member 21. As a result, the fall preventing member 21 is forcibly immersed in the protruding position. That is, since the train only contacts the forced retraction mechanism 100 and does not contact the fall preventing member 21, the mutual impact of the train and the fall preventing member 21 can be alleviated.

After forcibly immersing the fall preventing member 21 in this way, when the fall preventing member 21 protrudes back to the protruding position, the forced retraction mechanism 100 is applied to the fall preventing member 21 protruding to the protruding position. Since it operates continuously, it displaces to the position which can receive external force from a train, and can prepare for the next contact with a train.

Referring to the operation of the forced retraction mechanism 100 in more detail, the input member 110 in the first position is located at the protruding position of the fall prevention member 21 toward the track from the end edge 12 side of the platform 10. Extend at least to the same position.

Therefore, when the entering train does not contact the input member 110, the train does not touch the fall preventing member 21, but passes through the fall preventing member 21, thereby impacting the train or the fall preventing member 21. Not provided, the fall prevention member 21 can be used as usual.

In some situations, when the entering train contacts the input member 110, with an external force from the train, the input member 110 is displaced from the first position to the second position, so that the end edge of the platform 10 on the track side ( 12) At this time, the relay member 120 transmits the external force received by the input member 110 to the fall prevention member 21. As a result, the fall preventing member 21 is forcedly immersed in the protruding position.

Thus, instead of the fall prevention member 21, the input member 110 which receives external force from a train is arrange | positioned so that it can oscillate, for example in a 1st position and a 2nd position. When an external force is applied to the input member 110, the proximal end of the input member 110 rotates, and the force in the direction of rotation is converted into a force in the direction in which the relay member 120 immerses the fall preventing member 21. As a result, it is transmitted to the fall preventing member 21.

Also in the input member 110 as described above, when the fall preventing member 21 in the immersed state is projected again to the protruding position after the contact with the train, the input member 110 is operated in succession, from the second position side. When configured to extend to the first position, it is possible to prepare for contact with the expected train again.

In addition, in the said embodiment, although the whole fall prevention apparatus 20 was shown to consist of three fall prevention units 200, it is not limited to this, At least the fall prevention member 21 by the two or more plates 210 is shown. It may be divided. At this time, each of the two or more plates 210 may be guided by the guide member.

By dividing the fall prevention member 21 into two or more plates 210, each plate 210 becomes short and light, and when the fall prevention apparatus 20 is assembled, the handling of each plate 210 becomes easy and it is assembled. Improve workability

Further, for example, due to the surface precision of the bottom surface 16, which is the installation surface in the storage portion 15, and the product precision of the guide member installed on the bottom surface, height difference occurs between the guide members or with respect to the horizontal surface. In order to incline, there is a height difference between each plate 210 or an inclination occurs in each plate 210, but since each divided plate 210 is connected to each other, each plate is connected by the connected part. The height difference and the inclination of 210 can be absorbed, and each guide mechanism 40 can guide each plate 210 smoothly.

In addition, in the said embodiment, although the drive mechanism 30 was shown to be comprised by the nut member 36-bearing 39, it is not limited to this, For example, it is comprised by other mechanisms, such as a link mechanism, Also good.

Although the fall preventing member 21 is simply formed of a flat plate made of metal, the present invention is not limited thereto, and the fall preventing member 21 is used as a sandwich panel in consideration of light weight and impact absorbency. ) May be a honeycomb core. Accordingly, even if the train collides with the fall preventing member 21 in the protruding position, the honeycomb core deforms, so that the impact during the collision is absorbed, thereby preventing damage to the train, the drive mechanism 30, and the like. have. In this way, the fall preventing member 21 is made to achieve both the expected rigidity and the impact absorbency.

In addition, in this embodiment, although the forced retraction mechanism 100 has shown that it has the input member 110 and the relay member 120, it is not limited to this. That is, the forced retraction mechanism 100 has a rack fixedly fixed to the fall preventing member 21, a rack and a pinion mechanism composed of a pinion engaged with the rack, and the input member 110 swings. The ON may be rotated to immerse the fall preventing member 21 from the protruding position through the rack.

In addition, the forced retraction mechanism 100 is not limited to the link mechanism which consists of the input member 110 or the relay member 120, or the said rack and pinion mechanism. What is necessary is just to transmit the external force which the input member in a 2nd position, such as a cam mechanism, received to the fall prevention member 21.

In addition, although the electric motor 38 was provided as a power source, the fall prevention member 21 may be moved in and out by the driving force of an air cylinder or a hydraulic cylinder.

In addition, the place where the fall preventing device 20 is installed is not particularly limited, but the edge 12 of the platform 10 is bent, and the space between the edge 12 of the platform 10 and the train ( It is good to employ | adopt for S1) this wide part.

In addition, the upper surface of the fall preventing member 21 is formed in the shape of a bone ridge of thin unevenness, as in each step of the escalator apparatus, and is fitted with the upper surface of the fall preventing member 21 having such a shape. 15) The upper edge of the inlet on the side may be a thin wavy wave.

According to the fall prevention device of the platform according to the present invention, the fall prevention member is composed of two or more plates, and by engaging or connecting the adjacent ones of the two or more plates, each plate is short and light, so that the fall prevention device At the time of installation, handling of each plate is easy and assembly property improves. In addition, due to the surface accuracy of the mounting surface of the platform receiving part or the product precision of the fall prevention device, there is a height difference between each plate, or each plate is inclined, but each divided plate is engaged or connected to each other. Therefore, the engaging or connected part can absorb the height difference and the inclination of each plate, and it is necessary to raise the surface precision of the mounting surface, the product precision of the fall prevention device, or to adjust the position between the plates. This improves installation workability and lowers costs.

In addition, the fall prevention unit, which has been assembled in advance, is brought into the platform, and each fall prevention unit is arranged along the edge of the platform, so that the fall prevention device can be easily installed by the platform, further improving installation workability. .
