[1] Embodiment FIG. 1 shows the appearance of home equipment 1 according to an embodiment. The platform equipment 1 is installed on the track side of a platform 7 (platform) of a railway station, prevents passengers from falling from the platform 7, and enables them to get on and off when a railway vehicle arrives at the platform 7, and when getting on and off. It is a facility that plays a role in preventing falls. FIG. 1(a) shows the platform equipment 1 viewed from the track side, and FIG. 1(b) shows the platform equipment 1 viewed from vertically above.

The platform equipment 1 includes at least one platform door 3 and at least one homestep device 10. In this embodiment, a plurality of platform doors 3 and a plurality of homestep devices 10 are provided. Each platform door 3 has a door 4 and a storage section 5 . In this embodiment, the door 4 is arranged at a position facing the door of the stopped vehicle. The storage unit 5 stores the door 4 in the open position from one end in the horizontal direction (plays the role of a so-called door pocket).

In addition, the opposite end of the storage part 5 is in contact with the door 4 in the closed position to prevent passengers on the platform 7 from passing through to the track side. The open position is the position of the door 4 in the most open state, and the closed position is the position of the door 4 in the fully closed state. A plurality of platform doors 3 are arranged side by side over the entirety of the extension direction A3 of the platform 7 (also the extension direction of the railroad track) to separate the railroad side and the inner side of the platform 7 . The inner side here means a portion away from the outer side when the track side of the platform 7 is defined as the outer side. The railroad side and the inner side may be rephrased as the side closer to the railroad track (railway side) and the farther side (inner side) of the platform 7 .

The home step device 10 includes a housing 20 and a step 30, and is a device for taking in and out the step 30 accommodated in the housing 20. As shown in FIG. The housing 20 has a plate-like and hollow shape, and has an opening 21 on the track side. The step 30 is accommodated inside the housing 20 and driven by a driving means (to be described later) to be put in and taken out through the opening 21 of the housing 20 . A step 30 protrudes into the gap between the platform 7 and the stopped vehicle and serves as a foothold for passengers getting on and off.

The home step device 10 moves the steps 30 in a direction (protruding direction A1) toward the track side from the inside of the platform 7 described above so that the steps 30 protrude from the housing 20, and the step 30 in the protruding state is moved to the track. It is moved from the side toward the inner side of the home 7 (accommodating direction A2) to be accommodated in the housing 20.例文帳に追加The home step device 10 has a shape in which the dimension of the platform 7 in the extending direction A3 is longer than the dimension in the overhanging direction A1. It should be noted that the extension direction A3 of the platform 7 is assumed to be a direction orthogonal to the projecting direction A1 and the housing direction A2.

The platform 7 is provided with a notch 8 for installing the home step device 10 . A housing member 6 is installed in the notch 8 . The accommodation member 6 is a member installed in the notch 8 of the platform 7 to accommodate the home step device 10 . The housing member 6 has a shape of a hollow rectangular parallelepiped having four faces out of six faces except for the top face and the track-side side face, and has a box-like shape with a size capable of housing the home step device 10 inside. It is a member. The housing member 6 is fixed to the notch 8 by injecting a filler such as mortar between the housing member 6 and the notch 8 .

The home step device 10 is installed inside the housing member 6 fixed to the notch 8 . In this state, the home step device 10 has its upper surface 11 substantially flush with the upper surface of the platform 7, and its track-side side surface 12 (the side surface when the step 30 is accommodated) is the platform. It is installed so as to form substantially the same plane as the side surface of 7 . Storage units 5 for the platform doors 3 are installed above both ends of the home step device 10 installed on the platform 7 in the extension direction A3.

In this embodiment, the dimension of the step 30 in the extending direction A3 is approximately the same as the distance between the adjacent storage sections 5 (the width of the boarding/alighting path when the door 4 is opened). The platform doors 3 and the home step device 10 are electrically connected to a control device (not shown) so that the opening/closing of the door 4 and the step 30 are interlocked. Specifically, for example, when the vehicle stops, first the step 30 is extended and then the door 4 is opened. When the departure time comes, the door 4 is first closed, the step 30 is accommodated, and the vehicle departs. It should be noted that opening and closing and loading/unloading may be performed at timings different from this as long as the safety of passengers is ensured.

2 and 3 show the appearance of the homestep device 10. FIG. FIG. 2 shows the home step device 10 with the step 30 housed in the housing 20, and FIG. A step device 10 is shown. The housing 20 includes a main body portion 40 and a top plate portion 50 . The main body 40 is a box-shaped member having four sides of a hollow rectangular parallelepiped, excluding the vertically upper side and the side of the track.

The top plate portion 50 is a plate-like portion that covers the vertically upper portion of the main body portion 40 . The top plate portion 50 is made of metal or the like, and has a strength that does not easily deform even when stepped on by passengers. Anti-slip projections are formed on the upper surface of the top plate portion 50 . This non-slip projection is also formed on the upper surface of the step 30 . The top plate portion 50 is fixed with rivets to a top plate support member, which will be described later, inside the main body portion 40 . Once installed on the platform 7, the top plate is rarely removed, but if necessary for repairs or the like, the top plate can be removed by removing the rivets.

4 shows the appearance of the home step device 10 with the top plate portion 50 removed, and FIG. 5 shows its plan view. 5 and subsequent drawings, the non-slip projections are omitted for the sake of clarity. The home step device 10 includes a main body 40, a top plate support member 41-1 and four 41-2 (referred to as “top plate support member 41” when not distinguished), a motor drive unit 43, and an electromagnetic brake. It includes a portion 44 and guide rails 61 and 62 (referred to as "guide rail 60" when not distinguished from each other).

The body portion 40 has side plates 401 and 402, a rear plate 403, and a bottom plate 404, and has the four-sided shape described above. The top support member 41 is provided at a position corresponding to the end of each top and supports each top. The top plate support member 41-1 is attached to the vertically upper ends of the side plates 401 and 402 and the rear plate 403 of the main body 40. As shown in FIG. The top plate support member 41-2 is attached to a position of the bottom plate 404 where adjacent top plates are in contact with each other. Each top plate support member 41 is provided with a hole for attaching the above-described rivet, and each top plate is fixed.

The guide rail 60 is provided inside the housing 20 including the top plate portion 50 and guides the step 30 in the longitudinal direction of the own rail. Guide rail 60 is an example of the "rail" of the present invention. Since the guide rail 60 is provided so that the longitudinal direction is along the projecting direction A1, it guides the step 30 in the projecting direction A1 and the housing direction A2. The guide rail 61 is arranged on the right side of the center when the home step device 10 is viewed from the projecting direction A1, and the guide rail 62 is arranged on the left side of the center when the home step device 10 is viewed from the projecting direction A1. are placed in

The motor drive unit 43 has a motor 431 and a ball screw 432, and the ball screw 432 converts the rotational force of the motor 431 into a force in the extending direction A1, transmits the force to the step 30, and drives the step 30. do. In this manner, the motor drive unit 43 is a means that operates by electric power and moves the step 30 housed in the housing 20 in and out. The motor drive unit 43 is arranged at the center in the extension direction A3 when the home step device 10 is viewed from the extension direction A1. Step 30 will now be described with reference to FIG.

FIG. 6 represents step 30 . FIG. 6(a) shows the step 30 viewed from above, and FIG. 6(b) shows the step 30 viewed from the accommodation direction A2. The step 30 has a step portion 31 , a support portion 32 and a transmission portion 33 . The step portion 31 is a plate-like portion that protrudes from the housing 20 and is stepped on by passengers. The support portion 32 has rail portions 32-1 and 32-2 and a plate portion 32-3.

The rail portions 32-1 and 32-2 are arranged vertically above the guide rail 60 and supported by the guide rail 60. As shown in FIG. The rail portion 32-1 has a caster portion 35-1, which is movable on the rail, vertically downward, and the caster portion 35-1 moves on the guide rail 61. As shown in FIG. The rail portion 32-2 also has a caster portion 35-2 vertically downward, and the caster portion 35-2 moves on the guide rail 62. As shown in FIG.

The plate portion 32-3 is a plate-like member that is thicker than the step portion 31 and slightly smaller than the step portion 31, and supports substantially the entire step portion 31 from below vertically. In the plate portion 32-3, the rail portions 32-1 and 32-2 are welded to the plate portion 32-3, and the rail portions 32-1 and 32-2 are integrated to absorb the load of the passenger applied to the step portion 31. and support. The transmission portion 33 has a nut hole 34 into which the ball screw 432 of the motor drive portion 43 is inserted.

When the ball screw 432 inserted into the nut hole 34 rotates, the rotational force of the ball screw 432 is transmitted as driving force for linear movement. As described above, the step 30 is an integrated step that integrates the step portion 31 directly stepped on by the passenger and the support portion 32 that supports the step portion 31 and is also guided by the guide rails 60 .

Further, the home step device 10 moves the integrated step 30 guided in the longitudinal direction of the guide rail 60 by the driving force transmitted to the transmission portion 33 into and out of the housing 20 . The electromagnetic brake portion 44 is a portion that applies a brake to prevent the step 30 from moving in either the projecting direction A1 or the retracting direction A2 because it is dangerous if the step 30 moves in the projecting direction A1 or in the retracting direction A2. The electromagnetic brake portion 44 is installed so as to apply a brake by coming into contact with the rail portion 32-2.

In FIG. 5, guide rails 61 and 62 are attached to the body portion 40 . Since the guide rails 61 and 62 are members that guide the step 30 in the protruding direction A1 and the accommodation direction A2, smooth movement of the step 30 is hindered if they are not parallel to each other. The home step device 10 has a configuration for an operator to adjust the guide rails 61 and 62 so that they are parallel to each other and to fix the guide rails after the adjustment. The configuration for the parallel adjustment work and fixing work will be described with reference to FIG. 7 and subsequent figures.

FIG. 7 shows the body portion 40 . In FIG. 7, the illustration other than the part related to the guide rail 60 is omitted in order to make the figure easier to see. A plate-shaped base portion 45 elongated in the projecting direction A1 (receiving direction A2) is fixed to the main body portion 40 , and a guide rail 61 is fixed to the base portion 45 . These are fixed by screws, for example, but may be fixed by other methods (adhesive, etc.).

A plate-shaped base portion 46 that is elongated in the projecting direction A1 is fixed to the main body portion 40 . The base portion 46 has an elongated hole portion 47 in the projecting direction A1. A guide rail 62 and a rail base 63 are arranged in the hole portion 47 . The rail base 63 is a plate-like member elongated in the projecting direction A1, and the guide rail 62 is fixed vertically upward. The guide rail 62 is an example of the "rail" of the present invention, and the rail base 63 integrated with the guide rail 62 is an example of the "member integrated with the rail" of the present invention.

FIG. 8 shows the periphery of the guide rail 62 in an enlarged manner. 8(a) shows the guide rail 62 and the like as seen from the vertical direction, and FIG. 8(b) shows the guide rail 62 and the like as seen in the horizontal direction. As shown in the figure, the rail base 63 is smaller than the hole 47, so that it can change its horizontal and vertical position, orientation and inclination in the hole 47. there is

The guide rail 62 and the rail base 63 are provided with a screw hole 641 into which the screw 71 can be screwed and a screw hole 642 into which the screw 72 can be screwed. Further, the guide rail 62 is provided with a hole portion 651 in which the head of the screw 71 can be stored and a hole portion 652 in which the head of the screw 72 can be stored. The screws 71 and 72 are screws for adjusting the inclination of the guide rail 62 in the vertical direction A5 when the guide rail 62 is viewed in the horizontal direction, as will be described later. Say 70.

The tilt in the vertical direction A5 here means that a part of the guide rail moves in the vertical direction A5 from the state in which the longitudinal direction of the guide rail is along the horizontal direction (the state in which the tilt in the vertical direction A5 is 0). It is the inclination with respect to the horizontal direction. The screw holes 641 and 642 are referred to as screw holes 64 , and the hole portions 651 and 652 are referred to as hole portions 65 . The screw holes 64 pass through the guide rails 62 and the rail bases 63 .

The vertical adjustment screw 70 is a so-called full screw in which threads are cut over the entire shaft (bar-shaped portion), and the entire under-head portion (the portion excluding the head portion) can be screwed into the screw hole 64. It's becoming The vertical adjustment screw 70 is screwed into the screw hole 64 until the entire head of the vertical adjustment screw 70 enters the hole portion 65 . As a result, the vertical adjustment screw 70 does not protrude into the rail surface of the guide rail 62, so that the caster portion 35-2 of the step 30 is not damaged.

The vertical adjustment screw 70 has a length under the neck longer than that of the screw hole 64 , and the tip of the shaft protrudes from the screw hole 64 into the hole portion 47 . As shown in FIG. 8C, the tip of the screw 71 protrudes from the screw hole 641 by a length L1, and the tip of the screw 72 protrudes from the screw hole 642 by a length L2. By rotating the vertical adjustment screw 70, the lengths L1 and L2 of the protruded tip are changed.

The screw hole 641 and the screw hole 642 are provided at locations separated from each other in the extension direction A4 of the guide rail 62 . Therefore, when the lengths L1 and L2 change, the inclination of the guide rail 62 with respect to the horizontal direction changes. Thus, in the homestep device 10 , the tilt of the guide rail 62 with respect to the horizontal direction can be adjusted by the length of the vertical adjustment screw 70 projecting vertically downward from the screw hole 64 .

The operator who attaches the guide rail 62 to the main body 40 compares it with the already fixed guide rail 61 and adjusts the degree of screwing of the vertical adjustment screw 70 so that the inclination in the vertical direction A5 matches the guide rail 61. Adjust the lengths L1 and L2. When the inclinations of the guide rails 61 and 62 in the vertical direction A5 are aligned, the screwing of the vertical adjustment screw 70 is finished, and the inclination of the guide rails 62 in the vertical direction A5 is fixed in that state.

In this way, the homestep device 10 can be parallel-adjusted and fixed so that the guide rail 62 is parallel to another rail (the guide rail 61) when viewed in the horizontal direction. Moreover, as shown in FIG. 8, each of the vertical adjustment screws 70 can be screwed into the screw hole 64 from vertically above. This makes it easier to adjust the parallelism of the guide rail when viewed from the horizontal direction, compared to, for example, screwing the vertical adjustment screw 70 into the screw hole 64 from below.

Eight screws 81 to 88 are inserted into the rail base 63 . Hereinafter, these eight screws will be referred to as horizontal adjustment screws 80 unless otherwise distinguished. Each horizontal adjustment screw 80 is screwed into the base portion 46 after passing through the rail base 63 .
FIG. 9 shows an enlarged view of the periphery of the horizontal adjustment screw 80. As shown in FIG. In FIG. 9, the screws 83 and 84 are shown enlarged. 9(a) shows the screw 83 and the screw 84 as viewed vertically from above, and FIG. 9(b) shows a cross section of the portion where the screw 83 and the screw 84 are arranged.

The rail base 63 is provided with an insertion hole 93 into which the screw 83 can be inserted and an insertion hole 94 into which the screw 84 can be inserted. Hereinafter, they are referred to as insertion holes 90 unless otherwise distinguished. The insertion hole 90 is not internally threaded, and the horizontal adjustment screw 80 is simply inserted therein. On the other hand, the base portion 46 is provided with a screw hole 103 vertically below the insertion hole 93 into which the screw 83 can be screwed, and a screw hole 104 vertically below the insertion hole 94 into which the screw 84 can be screwed. ing. Below, they are referred to as screw holes 100 unless otherwise distinguished.

The insertion hole 90 has a rectangular shape elongated in the extension direction A3 of the home 7 . Therefore, even when the horizontal adjustment screw 80 is inserted into the insertion hole 90, the guide rail 62 and the rail base 63 can be moved in the extending direction A3. On the other hand, the dimension of the insertion hole 90 in the extension direction A4 of the guide rail 62 is shorter than the diameter of the head of the horizontal adjustment screw 80 . The protruding portion of the vertical adjustment screw 70 (screw 71 in FIG. 9) of the rail base 63 serves as a support bar (tension bar), and the base portion 46 cannot move beyond a distance corresponding to the length of the protruding portion. are kept away from

Therefore, when the horizontal adjustment screw 80 is screwed into the screw hole 100 , the head of the horizontal adjustment screw 80 presses the upper surface of the rail base 63 . At this time, the operator adjusts the positions of the guide rail 62 and the rail base 63 in the extending direction A3 so that the horizontal direction of the guide rail 61 matches that of the guide rail 61, while comparing with the already fixed guide rail 61. . When the horizontal orientations of the guide rails 61 and 62 are aligned, the horizontal orientation of the guide rail 62 is fixed by screwing in the horizontal adjustment screw 80 and pressing down the rail base 63. .

In this way, the home step device 10 is arranged parallel to the other rails when viewed from the vertical direction by means of the horizontal adjustment screws 80 inserted into the insertion holes 90 and screwed into the screw holes 100 with respect to the guide rails 62 . Parallel adjustment and fixation are possible. Specifically, as shown in FIG. 9(c), the horizontal direction of the guide rail 62 is adjusted by adjusting the position of the rail base 63 in the extending direction A3 at the four locations where the horizontal adjustment screws 80 are inserted. It is possible to match with the guide rail 61 .

In this embodiment, as described above, the two rails (guide rails 61 and 62) are aligned with each other by adjusting the vertical inclination (inclination with respect to the horizontal direction) of the rails with the two vertical adjustment screws 70 as described above. Can be installed parallel. Also, by adjusting the horizontal orientation of the rails with the eight horizontal adjustment screws 80, the two rails can be installed so as to be parallel to each other when viewed in the vertical direction.

In addition, in this embodiment, the simple work of screwing two vertical adjustment screws 70 into the screw holes 64 as much as necessary can be performed as the work of parallel adjustment when the guide rail is viewed in the horizontal direction. Further, in this embodiment, after performing the preceding work (work with the guide rail viewed in the horizontal direction), the work of adjusting the horizontal direction of the guide rail 62 and screwing in the eight horizontal adjustment screws 80 is performed. , as a later work (parallel adjustment work when the guide rail is viewed in the vertical direction).

Since this post-stage work does not affect the parallel relationship when the guide rail is viewed in the horizontal direction, it is not necessary to perform the post-stage work simultaneously with the post-stage work. In other words, according to this embodiment, the work in the former stage (work in which the guide rail is viewed in the horizontal direction) and the work in the latter stage (work in which the guide rail is viewed in the vertical direction) can be performed separately. parallel adjustment can be performed more easily than at the same time.

[2] Modifications The embodiment described above is merely an example of implementation of the present invention, and may be modified as follows. Moreover, the embodiment and each modification may be combined as necessary.

[2-1] Guide Rails Although the number of guide rails for guiding the steps is two in the embodiment, it is not limited to this and may be three or more. For example, when there are three guide rails, one is fixed first like the guide rail 61 and the remaining two are adjusted parallel like the guide rail 62 . In the case where there are three guide rails, if two guide rails are installed in parallel in advance, it is sufficient to adjust the remaining one in parallel like the guide rail 62 .

In short, the home step device has parallel adjustment and fixing for adjusting at least one of two or more rails for guiding the step so that it is parallel to the other rails when viewed in the horizontal and vertical directions. It should be possible. Thus, as in the embodiment, two or more rails can be installed parallel to each other when viewed horizontally, and two or more rails can be installed parallel to each other when viewed vertically. can be done.

Moreover, in the embodiment, the rail base 63 integrated with the guide rail 62 is provided, but the rail base 63 may not be provided. In that case, for example, the guide rail itself may have a shape in which the guide rail 62 and the rail base 63 are combined. In that case, the screw holes 64 and the insertion holes 90, which were provided in the member (rail base 63) integrated with the guide rail in the embodiment, are provided in the guide rail itself.

[2-2] Parallel Adjustment Screw The use of the screws (vertical adjustment screw 70 and horizontal adjustment screw 80) for parallel adjustment is not limited to that described in the embodiment. For example, although two vertical adjustment screws 70 are used in the embodiment, three or more may be used. In that case as well, at least two of the three screw holes into which the vertical adjustment screws 70 are screwed should be provided at locations separated in the extension direction A4 of the guide rail 62 . By doing so, the tilt of the guide rail 62 with respect to the horizontal direction can be adjusted.

Also, the vertical adjustment screw 70 may be screwed into the guide rail not from vertically above, but from vertically below. In that case, it takes time and effort to install the guide rail by changing the screwing degree of the vertical adjustment screw 70 and check the parallelism, but the hole shown in FIG. It is no longer necessary to provide a space such as 65 for housing the head of the screw.

Also, eight horizontal adjustment screws 80 are used in the embodiment, but the number may be less or more. Further, in the embodiment, the horizontal adjustment screw 80 is used as a set on both sides of the guide rail 62, but if the guide rail can be fixed with sufficient strength, the horizontal adjustment screw 80 may be used only on one side. . The horizontal adjustment screw 80 may also be provided at a location away from the guide rail 62 in the extending direction A4. By doing so, the horizontal direction of the guide rail 62 can be adjusted.

[2-3] Parallel adjustment method The parallel adjustment method may differ from that in the embodiment.
FIG. 10 shows an enlarged view of the periphery of the horizontal adjustment screw of this modified example. In the example of FIG. 10, a vertical adjustment screw 70 is screwed into the guide rail 62a that is not fixed to the rail base, similarly to the embodiment, to adjust the parallelism of the guide rail when viewed from the horizontal direction.

Further, screw holes 110a into which horizontal adjustment screws 80a can be horizontally screwed are formed in the base portion 46a at positions facing two side surfaces of the guide rail 62a. The horizontal direction of the guide rail 62a can be adjusted by screwing the horizontal adjustment screw 80a into the screw hole 110a from the outside and bringing the tip of the horizontal adjustment screw 80a into contact with the guide rail 62a.

Parallel adjustments may also be made without using screws directly. Parallel adjustment may be performed using a height adjusting device such as a jack (hydraulic or screw). Alternatively, the guide rail may be fixed by filling the hole 47 with a filler or a plate material after temporarily adjusting the parallelism with screws. In short, any method may be used as long as parallel adjustment and fixation are possible with respect to at least one of the two or more rails.
