Summary of the Invention

Problems to be Solved by the Invention

[0004] In the railway vehicle structure as described above, the number of wirings is large, and improvement in work efficiency in wiring processing at the site is required. However, in the conventional wiring holding structure, in order to prevent the wiring from contacting the adapter and wearing due to vibrations during the running of the railway vehicle, for example, measures are required to separate the wiring from the adapter with a separate member such as a wiring support, and there is room for improvement from the viewpoint of workability of wiring processing.

[0005] The present disclosure has been made to solve the above problems, and an object thereof is to provide a railway vehicle structure capable of improving the work efficiency of wiring processing.

Means for Solving the Problems

[0006] The gist of this disclosure is as follows:

[0007] [1] A railway vehicle body comprising a wiring retaining structure for holding wiring, wherein the wiring retaining structure comprises a retaining member held by a rafter member extending in the width direction of the railway vehicle body, and a suspension groove held by the retaining member and positioned below the rafter member, the retaining member having a main body portion including a fixing portion with the rafter member and a fixing portion with the suspension groove, and a protruding portion protruding from the main body portion.

[0008] In this railway vehicle structure, the holding member is provided with a protruding portion that extends from the main body. The presence of this protruding portion allows it to be used as a holding surface for wiring. This makes it possible to securely hold the wiring in the holding member to the extent that it does not move due to vibrations during railway vehicle operation, without the need for separate components such as wiring supports. By eliminating the need for separate components, sufficient workspace can be secured when holding the wiring, improving the efficiency of wiring work.

[0009] [2] The holding member is the railway vehicle structure according to [1], having a plurality of protrusions. In this case, the holding member can hold multiple types of wiring at different positions from each other.

[0010] [3] The railway vehicle structure according to [1] or [2], wherein the protruding portion protrudes from the main body portion to at least one side in the longitudinal direction of the railway vehicle structure. In this case, the length of the protruding portion that serves as a holding surface for the wiring can be secured, so that the holding member can hold the wiring more securely.

[0011] [4] The main body has a bent portion that partitions the space between the suspension groove and the rafter member in which the wiring is arranged when viewed from the longitudinal direction of the railway vehicle structure, and the protruding portion is provided on the bent portion, the railway vehicle structure according to any one of [1] to [3]. In this case, the wiring can be efficiently held in the space partitioned between the suspension groove and the rafter member.

[0012] [5] The railway vehicle structure according to any one of [1] to [4], wherein the protruding portion is provided at the fixing portion with the rafter member. The fixing portion with the rafter member in the main body is fixed to the rafter member. In this case, the effect of vibration during running can be reduced at the fixing portion with the rafter member. Since the wiring can be held at the fixing portion with the rafter member, the wiring can be held stably in the holding member.

[0013] [6] A railway vehicle structure according to any one of [1] to [5], wherein at least one of the main body and the protruding part is plate-shaped. In this case, because at least one of the main body and the protruding part is plate-shaped, the wiring can be held by the holding member over a surface area. Therefore, even when holding multiple wires, the wiring can be held securely by the holding member.

[0014] [7] The wiring holding structure comprises a plurality of holding members held at predetermined intervals on the rafter member, and an intermediate holding member disposed between the plurality of holding members, wherein the intermediate holding member has an intermediate main body portion detachably attached to the suspension groove, and an intermediate projection portion projecting from the intermediate main body portion in the direction of projection of the projection portion of the holding member, as described in any of [1] to [6]. In this case, the intermediate holding member can hold the wiring between the plurality of holding members. Since the intermediate main body portion of the intermediate holding member is detachably attached to the suspension groove, the intermediate holding member can be attached to the suspension groove at any time after the work of holding the wiring to the holding member is completed. Therefore, the work of holding the wiring to the holding member is not hindered by the intermediate holding member, and the work efficiency of the wiring process can be maintained.

[0015] [8] The railway vehicle structure according to [7], wherein the width of the intermediate main body in the longitudinal direction of the railway vehicle structure is smaller than the width of the main body in the longitudinal direction of the railway vehicle structure. In this case, sufficient space can be secured for holding wiring between the multiple holding members, while the intermediate holding member can hold the wiring more securely.

[0016] [9] The intermediate holding member is the railway vehicle structure according to [7] or [8], which has a plurality of the intermediate protruding portions. In this case, in the intermediate holding member, a plurality of types of wirings can be held at different positions from each other.

[0017]

[10] The protruding portion protrudes from the main body portion to at least one side in the longitudinal direction of the railway vehicle structure, and the intermediate protruding portion protrudes from the intermediate main body portion to at least one side in the longitudinal direction of the railway vehicle structure. The railway vehicle structure according to any one of [7] to [9]. In this case, since the length of the intermediate protruding portion that serves as the holding margin for the wiring can be ensured, the wiring can be held more firmly on the intermediate holding member.

[0018]

[11] At least one of the intermediate main body portion and the intermediate protruding portion is plate-shaped. The railway vehicle structure according to any one of [7] to

[10] . In this case, since at least one of the intermediate main body portion and the intermediate protruding portion is plate-shaped, the wiring can be held on the intermediate holding member in a planar manner. Therefore, even when holding a plurality of wirings, the wiring can be held firmly on the intermediate holding member.

Mode for Carrying out the Invention

[0021] Hereinafter, a preferred embodiment of a railway vehicle structure according to one aspect of the present disclosure will be described in detail with reference to the drawings. In the description of the drawings, the same or corresponding elements are denoted by the same reference numerals, and redundant descriptions are omitted.

[0022] [First Embodiment] FIG. 1 is a perspective view of a railway vehicle structure according to the first embodiment of the present disclosure. As shown in FIG. 1, the railway vehicle structure 1 includes a floor structure 2, a side structure 3, a roof structure 4, and a fascia structure 5, and these structures are joined to each other to form a box-shaped shape having a space for accommodating passengers inside.

[0023] The floor structure 2 is disposed at the bottom of the railway vehicle structure 1 as a structure constituting the floor portion of the vehicle. The side structure 3 and the fascia structure 5 are erected so as to surround the left and right edges and the front and rear edges of the floor structure 2 as structures constituting the side portions of the vehicle. A plurality (for example, three) of door portions 6 for passengers and crew to get on and off are provided at equal intervals on the side structure 3.

[0024] Furthermore, window sections 7 are provided between the door sections 6, 6 and at both ends of the side structure 3. The end structure 5 is provided with a passage section 8 for passengers and crew to move between vehicles in a train consisting of multiple connected vehicles. The roof structure 4 is positioned on top of the railway vehicle's structure as a structure that constitutes the roof of the vehicle, covering the space. The roof structure 4 of the vehicle is equipped with an outdoor unit 9 of an air conditioning unit (air conditioner) and a pantograph (not shown) at the top to regulate the temperature inside the vehicle.

[0025] The railway vehicle body 1 described above is equipped with various electrical devices such as passenger compartment lighting and liquid crystal display panels. Therefore, the railway vehicle body 1 is provided with multiple wiring bundles P1 to P4 (see Figures 2 and 4) that are connected to the electrical devices, and a wiring holding structure 10 (described later) is provided to hold these wiring bundles. Wiring P1 to P4 are, for example, through-wires arranged in the longitudinal direction of the railway vehicle body 1 on the inside (ceiling) of the roof structure 4. Wiring P1 to P4 include, for example, signal lines for data communication including Ethernet (trademark registration no. 1702119), AC and DC lines for power transmission, and shielding wires that protect signals from electrical interference.

[0026] Figure 2 is a perspective view showing a wiring retention structure according to the first embodiment. The railway vehicle body 1 has a wiring retention structure 10 that holds the aforementioned wirings P1 to P4 (only wirings P1 and P2 are shown in Figure 2). The wiring retention structure 10 comprises a suspension groove 30 and a retaining member 20 for holding the suspension groove 30. The railway vehicle body 1 is provided with rafter members T located below the roof structure 4 (not shown in Figure 2) as members related to the installation of the wiring retention structure 10. The rafter members T are arranged at predetermined intervals in the longitudinal direction of the railway vehicle body 1. In this embodiment, the rafter members T have a Z-shaped cross-section and extend in the width direction of the railway vehicle body 1 while curving along the curved shape of the roof structure 4.

[0027] The retaining member 20 is held by the rafter member T. More specifically, the retaining member 20 is held by the surface of the rafter member T facing the interior side of the railway vehicle structure 1. The wiring retaining structure 10 comprises a plurality of retaining members 20, which are arranged at predetermined intervals in the longitudinal direction of the railway vehicle structure 1 in accordance with the arrangement of the rafter members T. The predetermined interval means, for example, a sufficient interval between the plurality of retaining members 20 to hold the wiring P1 and P2. The predetermined interval is, for example, about 200 mm to 700 mm. In this embodiment, the arrangement interval of the plurality of retaining members 20 coincides, for example, with the arrangement interval of the rafter members T in the longitudinal direction of the railway vehicle structure 1.

[0028] The suspension groove 30 supports interior components, for example, that are placed inside the railway vehicle body 1. The suspension groove 30 is a hollow rail member with a linear opening in the central part of one side (for example, the side facing downwards). The suspension groove 30 is held by the holding member 20 and, in this embodiment, extends in the longitudinal direction of the railway vehicle body 1 below the rafter member T. The suspension groove 30 is fixed to the holding member 20 with its opening facing downwards.

[0029] Figure 3 is a perspective view showing the retaining member. The retaining member 20 is made of a metal such as stainless steel or an aluminum alloy, in order to provide sufficient rigidity for holding the suspension groove 30. The retaining member 20 has a main body portion 21 that is plate-shaped with a certain width. The width of the main body portion 21 in the width direction (corresponding to the longitudinal direction of the railway vehicle body 1) is, for example, the same as or slightly smaller than the width of the rafter member T in the longitudinal direction of the railway vehicle body 1.

[0030] The main body portion 21 has a first fixing portion 22, a second fixing portion 23, and a bent portion 24. The first fixing portion 22 and the second fixing portion 23 are portions used for fixing to the rafter member T and have a curved shape corresponding to the curved shape of the rafter member T. The first fixing portion 22 is located at one end of the main body portion 21 in the longitudinal direction (corresponding to the width direction of the railway vehicle structure 1). The second fixing portion 23 is located at the other end of the main body portion 21 in the longitudinal direction. When the holding member 20 is attached to the rafter member T, the first fixing portion 22 is located on the central side in the width direction of the railway vehicle structure 1, and the second fixing portion 23 is located on the end side in the width direction of the railway vehicle structure 1.

[0031] The first fixing portion 22 has, for example, a through hole 22a with a circular cross-section, and the second fixing portion 23 has a through hole 23a similar to the through hole 22a. The holding member 20 is firmly fixed to the rafter member T by bringing both the first fixing portion 22 and the second fixing portion 23 into contact with the rafter member T and, for example, welding them. At this time, a method called plug welding, which welds the inside of the through holes 22a and 23a, may be used, or the inner edges of the through holes 22a and 23a may be welded. The welding method is selected according to the diameter of the through holes 22a and 23a.

[0032] The bent portion 24 is located in the central part of the main body 21, between the first fixing portion 22 and the second fixing portion 23. The bent portion 24 has a first connecting portion 24a on the side of the first fixing portion 22, a central third fixing portion 24b (fixing portion with the suspension groove 30), and a second connecting portion 24c on the side of the second fixing portion 23. The bent portion 24 is bent in a U-shape overall, so as to protrude toward one side in the thickness direction of the main body 21 (corresponding to the vertical direction of the railway vehicle body 1). The connecting portion between the first fixing portion 22 and the first connecting portion 24a, the connecting portion between the first connecting portion 24a and the third fixing portion 24b, the connecting portion between the third fixing portion 24b and the second connecting portion 24c, and the connecting portion between the second connecting portion 24c and the second fixing portion 23 all have a rounded shape.

[0033] The retaining member 20 is fixed to the rafter member T such that the bent portion 24 protrudes downward from the rafter member T. When the retaining member 20 is attached to the rafter member T, the bent portion 24 and the rafter member T form a closed space S when viewed from the longitudinal direction of the railway vehicle structure 1. This bent portion 24 allows the retaining member 20 to partition the wiring space into an inside and outside space S.

[0034] The third fixing portion 24b is the part that fixes the suspension groove 30 and has a flat surface for fixing the suspension groove 30. The third fixing portion 24b is separated from the first fixing portion 22 and the second fixing portion 23 on one side in the thickness direction of the main body portion 21 and is located in the central part in the length direction of the main body portion 21. The suspension groove 30 is firmly fixed to the holding member 20 by bringing the third fixing portion 24b into contact with the upper part of the suspension groove 30 and, for example, welding it. The holding member 20 and the suspension groove 30 may be integrally welded together.

[0035] The retaining member 20 has a plurality of protrusions (protrusions 25, 26, 27) that project from the main body 21 in the width direction of the main body 21. In this embodiment, when the retaining member 20 is attached to the rafter member T, the protrusions 25, 26, 27 extend in the longitudinal direction of the railway vehicle structure 1. The protrusions 25, 26, 27 are, for example, rectangular plate-shaped with rounded corners. The protrusion 25 is provided on the first fixing part 22. The protrusion 25 is formed at a position offset from the end of the first fixing part 22 in the longitudinal direction of the main body 21 toward the center in the longitudinal direction of the main body 21.

[0036] The protruding portion 25 has a first protruding portion 25a and a second protruding portion 25b that protrude from both sides in the width direction of the main body portion 21, flush with the first fixing portion 22. When the holding member 20 is attached to the rafter member T, the first protruding portion 25a protrudes from the first fixing portion 22 to one side in the longitudinal direction of the railway vehicle body 1, and the second protruding portion 25b protrudes from the first fixing portion 22 to the other side in the longitudinal direction of the railway vehicle body 1.

[0037] The width of the first projection 25a in the width direction of the main body 21 is, for example, the same as the width of the second projection 25b in the width direction of the main body 21. In the portion of the main body 21 where the projection 25 is provided, the width of the holding member 20 in the width direction of the main body 21 is the sum of the lengths of the first projection 25a, the first fixing portion 22, and the second projection 25b in the width direction of the main body 21. In other words, in the holding member 20, the width of the portion where the projection 25 is provided is wider than the width of the portion where the projection 25 is not provided.

[0038] The protruding portion 26 is provided on the first connecting portion 24a of the bent portion 24. The protruding portion 26 has a first protruding portion 26a and a second protruding portion 26b that protrude on both sides in the width direction of the main body portion 21, flush with the first connecting portion 24a. When the holding member 20 is attached to the rafter member T, the protruding portion 26 is located on the opposite side from the side structure 3 (not shown in Figure 3) with respect to the suspension groove 30. The other aspects of the protruding portion 26 are the same as those of the protruding portion 25.

[0039] The protruding portion 27 is provided on the second connecting portion 24c of the bent portion 24. The protruding portion 27 has a first protruding portion 27a and a second protruding portion 27b that protrude on both sides in the width direction of the main body portion 21, flush with the second connecting portion 24c. When the holding member 20 is attached to the rafter member T, the protruding portion 27 is located on the side structure 3 side with respect to the suspension groove 30. The protruding portion 27 is inclined with respect to the protruding portion 26. The other aspects of the protruding portion 27 are the same as those of the protruding portions 25 and 26.

[0040] In this embodiment, the main body 21 and the protruding parts 25, 26, and 27 may be integrally molded by press molding or the like. At least one of the protruding parts 25, 26, and 27 may be made of a separate component from the main body 21. At least one of the protruding parts 25, 26, and 27 may be made of a separate component from the main body 21 and be detachably attached to the main body 21.

[0041] Figure 4 shows an example of how wiring is held by a retaining member. In the example in Figure 4, wiring P3 is provided in the space S between the rafter member T and the suspension groove 30, for example, wirings P1, P2, and P4 are provided outside the space S.

[0042] The wiring P1 is held by the protrusion 25 of the holding member 20. At the position where the wiring P1 is held by the protrusion 25, a protective material Pa, such as a sheet of rubber, is wrapped around the wiring bundle formed by the wiring P1. The protective material Pa prevents the wiring P1 to P4 from coming into contact with the holding member 20 and wearing down due to vibrations of the railway vehicle while it is running. Multiple fasteners Pb are attached so as to surround the protective material Pa and the protrusion 25 while they are in contact with each other. Examples of fasteners Pb include binding members such as cable ties. Here, a pair of fasteners Pb are used for the wiring bundle of wiring P1. One fastener Pb is attached to the first protrusion 25a, and the other fastener Pb is attached to the second protrusion 25b.

[0043] Wiring P2 is fixed to a projection 26 facing away from space S. Wiring P3 is fixed to a projection 26 facing towards space S. Wiring P4 is held by a projection 27 facing away from space S. The attachment of wirings P2 to P4 to the holding member 20 is the same as for wiring P1.

[0044] Figure 5 shows a comparative example of how wiring is held by the holding member. As shown in Figure 5, the wiring holding structure 10X in the comparative example differs from the wiring holding structure 10 in this embodiment in that the holding member 20X does not have configurations corresponding to the protrusions 25, 26, and 27.

[0045] In the wiring holding structure 10X of the comparative example, the wirings P1 to P4 are not fixed to the holding member 20X. In such a wiring holding structure 10X, since the holding member 20X does not have a structure corresponding to the protrusions 25, 26, and 27, it is necessary to separate the wirings P1 to P4 from the holding member 20X using the wiring support 100 so that the wirings P1 to P4 do not come into contact with the holding member 20X and wear down due to vibrations during the operation of the railway vehicle.

[0046] However, for example, inside the roof structure 4, at the location where the outdoor unit 9 is placed, the space available for wiring may be narrow due to the placement of peripheral equipment for the outdoor unit 9, such as the air conditioning control device. When placing the wiring support 100 in a narrow space, it may become difficult for workers' hands and tools to enter the space, potentially reducing the efficiency of wiring work.

[0047] In contrast, the railway vehicle body 1 has a holding member 20 provided with protrusions 25, 26, and 27 that project from the main body 21 in the longitudinal direction of the railway vehicle body 1. Because the holding member 20 has protrusions 25, 26, and 27, these protrusions can be used as holding surfaces for the wiring P1 to P4. This makes it possible to securely hold the wiring P1 to P4 in the holding member 20 to the extent that it does not move due to vibrations during the operation of the railway vehicle, without using a separate component such as a wiring support 100. By eliminating the need for a separate component, sufficient workspace can be secured when holding the wiring P1 to P4, improving the efficiency of the wiring process. Furthermore, the time required for wiring can be reduced.

[0048] Furthermore, by not providing the wiring support 100, the space available for arranging peripheral equipment around the outdoor unit 9 inside the roof structure 4 is reduced, and excessive pressure on the wiring P1 to P4 can be suppressed. This reduces damage to the wiring P1 to P4. In addition, by not providing the wiring support 100, the cost of wiring work can be reduced.

[0049] In this embodiment, the holding member 20 has a plurality of protrusions (protrusions 25, 26, 27). In this case, the holding member 20 can hold multiple types of wiring at different positions from each other.

[0050] In this embodiment, the protrusions 25, 26, and 27 protrude from the main body 21 on both sides in the longitudinal direction of the railway vehicle structure 1. In this case, the length of the protrusions 25, 26, and 27 that serve as the holding area for the wiring P1 to P4 can be further secured, so that the holding member 20 can hold the wiring P1 to P4 even more securely.

[0051] In this embodiment, the main body 21 has a bent portion 24 that partitions the space S between the suspension groove 30 and the rafter member T where the wiring P3 is arranged, when viewed from the longitudinal direction of the railway vehicle body 1, and the protruding portions 26 and 27 are provided on the bent portion 24. In this case, the wiring P3 can be efficiently held in the space S partitioned between the suspension groove 30 and the rafter member T.

[0052] In this embodiment, the protruding portion 25 is provided on the first fixing portion 22 with respect to the rafter member T. The first fixing portion 22 with respect to the rafter member T in the main body portion 21 is fixed to the rafter member T. In this case, the first fixing portion 22 with respect to the rafter member T prevents the wiring P1 from coming into contact with the rafter member T. Since the wiring P1 can be held by the first fixing portion 22 with respect to the rafter member T, the wiring P1 can be stably held by the holding member 20.

[0053] In this embodiment, at least one of the main body portion 21 and the protruding portions 25, 26, and 27 is plate-shaped. In this case, because at least one of the main body portion 21 and the protruding portions 25, 26, and 27 is plate-shaped, the wiring P1 to P4 can be held by the holding member 20 over a surface area. Therefore, even when holding multiple wirings, the wiring P1 to P4 can be securely held by the holding member 20.

[0054] [Examples of retaining members] Figure 6 is a perspective view showing a modified example of a retaining member. As shown in Figure 6, the railway vehicle body 1 according to this modified example differs from the first embodiment in that the wiring retaining structure 10 is provided on a rafter member T with a Z-shaped cross-section, in that the wiring retaining structure 10A is provided on a hat-shaped rafter member TA with an inverted U-shaped cross-section. Accordingly, the wiring retaining structure 10A in this modified example has a retaining member 20A whose main body portion 21A is wider than that of the retaining member 20.

[0055] The rafter member TA, as a whole, has a shape similar to the rafter member T, aligned with the width direction of the railway vehicle structure 1. The rafter member TA has a top Ta, a pair of flanges Tb, and a pair of webs Tc. In a cross-section along the longitudinal direction of the railway vehicle structure 1, the top Ta extends in the longitudinal direction of the railway vehicle structure 1 and is located at the top of the rafter member TA. The top Ta may be fixed to the roof structure 4. The pair of flanges Tb extend in the longitudinal direction of the railway vehicle structure 1 and are aligned in the longitudinal direction of the railway vehicle structure 1. The flanges Tb are located at the bottom of the rafter member TA. The pair of webs Tc extend in the vertical direction of the railway vehicle structure 1 and are aligned in the longitudinal direction of the railway vehicle structure 1. The webs Tc are located between the top Ta and the flanges Tb.

[0056] The main body portion 21A of the retaining member 20A has a first fixing portion 22A, a second fixing portion 23A, and a bent portion 24A. The length of the first fixing portion 22A in the width direction of the main body portion 21A (corresponding to the longitudinal direction of the railway vehicle structure 1) is longer than the length of the first fixing portion 22 (first embodiment) in the width direction of the main body portion 21, according to the dimensions of the rafter member TA. For example, the length of the first fixing portion 22A in the longitudinal direction of the railway vehicle structure 1 matches the length of the rafter member TA in the longitudinal direction of the railway vehicle structure 1, and the first fixing portion 22A is fixed to both of the pair of flanges Tb of the rafter member TA. The dimensions and arrangement of the second fixing portion 23A are the same as those of the first fixing portion 22A.

[0057] The first fixing portion 22A and the second fixing portion 23A have, for example, a plurality of through holes 22Aa with a circular cross-section. The plurality of through holes 22Aa are arranged in the longitudinal direction of the railway vehicle structure 1. The configuration of the other through holes 22Aa is the same as that of the through holes 22a. The length of the bent portion 24A in the width direction of the main body portion 21A is longer than the width of the bent portion 24 (first embodiment) in the width direction of the main body portion 21, according to the dimensions of the rafter member TA.

[0058] In this modified example, as in the first embodiment, it is possible to firmly hold the wiring P1 to P4 in the holding member 20 to the extent that the wiring P1 to P4 does not move due to vibrations during the operation of the railway vehicle, even without using a separate member such as a wiring support 100 for the holding member 20A. By omitting the separate member, sufficient workspace can be secured when holding the wiring P1 to P4, improving the efficiency of the wiring process. In addition, the time required for wiring processing can be reduced.

[0059] [Second Embodiment] Figure 7 is a perspective view showing the wiring holding structure according to the second embodiment. Figure 8 is a perspective view showing the intermediate holding member. As shown in Figures 7 and 8, the railway vehicle body 1B according to the second embodiment differs from the wiring holding structure 10 of the first embodiment, which is configured without the intermediate holding member 40, in that the wiring holding structure 10B further comprises the intermediate holding member 40.

[0060] The intermediate holding member 40 is a member that further holds the wiring P1 to P4 between the holding members 20 which are arranged at predetermined intervals in the longitudinal direction of the railway vehicle body 1. The intermediate holding member 40 is made of a metal including, for example, stainless steel or aluminum alloy, from the viewpoint of providing sufficient rigidity for holding the wiring, as will be described later. The intermediate holding member 40 has an intermediate main body portion 43 which is detachably attached to the suspension groove 30. The intermediate main body portion 43 is in the shape of a rectangular plate with rounded corners and is located in the center of the intermediate holding member 40.

[0061] The intermediate body section 43 is bent so that both ends in the longitudinal direction of the intermediate body section 43 (corresponding to the width direction of the railway vehicle body 1B) face each other, and when viewed from the width direction of the intermediate body section 43 (corresponding to the longitudinal direction of the railway vehicle body 1B), it has a U-shape. The bent portion of the intermediate body section 43 has a rounded shape. The intermediate body section 43 has a first section 43a, a second section 43b, and a third section 43c that are aligned in the longitudinal direction of the intermediate body section 43. The directions in which the first section 43a and the third section 43c extend are perpendicular to the direction in which the second section 43b extends.

[0062] The second part 43b is attached to the lower part of the suspension groove 30 and is located in the central part of the intermediate main body 43. Multiple through holes (not shown) are formed in the second part 43b, and fixing members such as bolts provided in the suspension groove 30 are inserted through these through holes. The heads of the bolts are located inside the suspension groove 30, and the lower part of the bolts is exposed from the suspension groove 30 as the bolt heads catch on the rails of the suspension groove 30. The intermediate holding member 40 is firmly attached to the suspension groove 30 by aligning the position of the bolts provided in the suspension groove 30 with the desired position for installing the intermediate holding member 40, inserting the bolts through the through holes, and then screwing a fixing member such as a nut onto the lower part of the bolts with a washer.

[0063] When the intermediate holding member 40 is attached to the suspension groove 30, the intermediate main body portion 43 is bent to follow the outer circumference of the suspension groove 30. The first portion 43a and the third portion 43c are aligned in the vertical direction of the railway vehicle body 1B, and the second portion 43b is aligned in the width direction of the railway vehicle body 1B. The first portion 43a is located on the side of the side structure 3 relative to the suspension groove 30, and the third portion 43c is located on the opposite side of the side structure 3 relative to the suspension groove 30. The second portion 43b is located below the suspension groove 30. The intermediate main body portion 43 is detachable from the suspension groove 30 along the vertical direction of the railway vehicle body 1B.

[0064] The width of the intermediate main body portion 43 of the intermediate holding member 40 in the longitudinal direction of the railway vehicle body 1B is smaller than the width of the main body portion 21 of the holding member 20 in the longitudinal direction of the railway vehicle body 1B. The width of the intermediate main body portion 43 in the longitudinal direction of the railway vehicle body 1B is smaller than the width of the wiring support 100 (see Figure 5) in the longitudinal direction of the railway vehicle body 1X. The width of the intermediate holding member 40 in the longitudinal direction of the railway vehicle body 1B is, for example, about 100 mm to 150 mm.

[0065] The intermediate holding member 40 has a plurality of intermediate protrusions (intermediate protrusions 45, 46) that project from the intermediate main body 43 in the width direction of the intermediate main body 43. The intermediate protrusions 45, 46 are formed including the end of the intermediate main body 43. The intermediate protrusions 45, 46 are, for example, rectangular plate-shaped with rounded corners.

[0066] The intermediate projection 45 has a first projection 45a and a second projection 45b that are flush with the first portion 43a and project outwards on both sides in the width direction of the intermediate main body 43. The first projection 45a projects outwards from the intermediate main body 43 to one side in the width direction, and the second projection 45b projects outwards from the intermediate main body 43 to the other side in the width direction. The width of the first projection 45a in the width direction of the intermediate main body 43 is, for example, the same as the width of the second projection 45b in the width direction of the intermediate main body 43, but the width of the first projection 45a and the width of the second projection 45b in the width direction of the intermediate main body 43 may be different from each other.

[0067] In the portion of the intermediate main body 43 where the intermediate protrusion 45 is provided, the width of the intermediate holding member 40 in the width direction of the intermediate main body 43 is equal to the combined length of the first protrusion 45a, the intermediate main body 43, and the second protrusion 45b in the width direction of the intermediate main body 43. In other words, in the intermediate holding member 40, the width of the portion where the intermediate protrusion 45 is provided is wider than the width of the portion where the intermediate protrusion 45 is not provided.

[0068] The intermediate projection 46 has a first projection 46a and a second projection 46b that protrude from both sides in the width direction of the intermediate main body 43, flush with the third portion 43c. The intermediate projection 46 is arranged to be substantially parallel to the intermediate projection 45. The other configurations of the intermediate projection 46 are the same as those of the intermediate projection 45.

[0069] In this embodiment, the intermediate main body portion 43 and the intermediate protrusions 45, 46 may be integrally molded by press molding or the like. At least one of the intermediate protrusions 45, 46 may be made of a separate component from the intermediate main body portion 43. At least one of the intermediate protrusions 45, 46 may be made of a separate component from the intermediate main body portion 43 and be detachably attached to the intermediate main body portion 43.

[0070] When the intermediate holding member 40 is attached to the suspension groove 30, the intermediate protrusions 45 and 46 extend in the longitudinal direction of the railway vehicle body 1. The intermediate protrusions 45 and 46 project from the intermediate main body 43 in the direction of the protrusions 25, 26, and 27 of the holding member 20. The intermediate protrusion 45 is located on the side body 3 side relative to the suspension groove 30, and the intermediate protrusion 46 is located on the interior side of the railway vehicle body 1B relative to the suspension groove 30. Each of the intermediate protrusions 45 and 46 faces in the width direction of the railway vehicle body 1B.

[0071] As shown in Figure 7, for example, wiring P2 is held not only by the holding member 20 but also by an intermediate projection 46 on the intermediate holding member 40 that faces away from the suspension groove 30. The manner in which wiring P2 is fixed to the intermediate projection 46 is the same as the manner in which wiring P1 to P4 are fixed to projections 25, 26, and 27 described above. The wiring may be fixed to both sides or one side of the intermediate projection 45, or to both sides of the intermediate projection 46.

[0072] As described above, the wiring holding structure 10B comprises a plurality of holding members 20 arranged at predetermined intervals in the longitudinal direction of the railway vehicle body 1B, and an intermediate holding member 40 positioned between the plurality of holding members 20. The intermediate holding member 40 has an intermediate main body portion 43 that is detachably attached to the suspension groove 30, and intermediate protrusions 45 and 46 that project from the intermediate main body portion 43 in the longitudinal direction of the railway vehicle body 1B. In this case, the intermediate holding member 40 can hold the wiring between the plurality of holding members 20. Since the intermediate main body portion 43 of the intermediate holding member 40 is detachably attached to the suspension groove 30, the intermediate holding member 40 can be attached to the suspension groove 30 at any time after the work of holding the wiring to the holding members 20 is completed. Therefore, the work of holding the wiring to the holding members 20 is not hindered by the intermediate holding member 40, and the work efficiency of the wiring process can be maintained.

[0073] Furthermore, if the spacing between the retaining members 20 is long, the intermediate retaining members 40 placed between the retaining members 20 can suppress the deflection of the wiring P1 to P4, thereby suppressing wear of the wiring P1 to P4 due to vibrations of the railway vehicle while it is in motion.

[0074] Furthermore, since the intermediate holding member 40 can be installed at the required position, if branching is required in the wiring P1 to P4, the intermediate holding member 40 can be used as the branching point for the wiring branching process. This improves the quality of the wiring process. In addition, by placing the intermediate holding member 40 at the branching point, wear of the wiring P1 to P4 due to vibration, etc., can be suppressed at that branching point.

[0075] In this embodiment, the width of the intermediate main body portion 43 in the longitudinal direction of the railway vehicle body 1B is smaller than the width of the main body portion 21 in the longitudinal direction of the railway vehicle body 1B. In this case, sufficient space can be secured for holding the wiring between the multiple holding members 20, while the intermediate holding member 40 can hold the wiring even more securely. Furthermore, since the intermediate holding member 40 is smaller than the wiring support 100, the wiring can be held with a compact configuration.

[0076] In this embodiment, the intermediate holding member 40 has a plurality of intermediate protrusions (intermediate protrusions 45, 46). In this case, the intermediate holding member 40 can hold multiple types of wiring at different positions from each other.

[0077] In this embodiment, the intermediate protrusions 45 and 46 protrude from the intermediate main body 43 to both sides in the longitudinal direction of the railway vehicle body 1B. In this case, the length of the intermediate protrusions 45 and 46 that serve as the holding area for the wiring can be further secured, so that the wiring can be held more securely by the intermediate holding member 40.

[0078] In this embodiment, at least one of the intermediate main body portion 43 and the intermediate protrusions 45, 46 is plate-shaped. In this case, because at least one of the intermediate main body portion 43 and the intermediate protrusions 45, 46 is plate-shaped, the wiring can be held by the intermediate holding member 40 over a surface area. Therefore, even when holding multiple wires, the wiring can be securely held by the intermediate holding member 40.

[0079] [First modified example of the intermediate holding member] Figure 9 is a perspective view showing the intermediate holding member according to the first modified example. The intermediate holding member 40 according to the first modified example differs from the intermediate holding member 40 of the second embodiment, in that the intermediate protrusion 45 is inclined with respect to the intermediate protrusion 46, while the two are substantially parallel.

[0080] When the intermediate holding member 40 is attached to the suspension groove 30, the intermediate projection 45 is located on the side structure 3 side relative to the suspension groove 30. The intermediate projection 45 is inclined with respect to the width direction and the vertical direction of the railway vehicle structure 1B. For example, the inclination angle of the intermediate projection 45 with respect to the width direction of the railway vehicle structure 1B is the same as the inclination angle of the projection 27 of the holding member 20 with respect to the width direction of the railway vehicle structure 1B.

[0081] In this modified example, the same effects as in the second embodiment can be obtained, and the inclination angle of the intermediate protrusion 45 with respect to the width direction of the railway vehicle body 1B matches the inclination angle of the protrusion 27 of the holding member 20 with respect to the width direction of the railway vehicle body 1B. Therefore, it is possible to easily hold the wiring fixed to the protrusion 27 of the holding member 20 at the intermediate protrusion 45 of the intermediate holding member 40.

[0082] [Second modified example of the intermediate holding member] Figure 10 is a perspective view showing an intermediate holding member according to a second modified example. The wiring holding structure 10D according to the second modified example differs from the wiring holding structure 10B of the second embodiment, which has intermediate protrusions 45 and 46 facing the width direction of the railway vehicle body 1B, in that when the intermediate holding member 40D is attached to the suspension groove 30, it has an intermediate protrusion 47 facing the vertical direction of the railway vehicle body 1B.

[0083] The intermediate main body portion 43D of the intermediate holding member 40D is, for example, a rectangular plate with rounded corners. The intermediate main body portion 43D is bent so that both ends face each other in one direction, and when viewed from the width direction of the intermediate main body portion 43D (corresponding to the longitudinal direction of the railway vehicle body 1B), it has a U-shape. The intermediate main body portion 43D has a first portion 43d, a second portion 43e, and a third portion 43f that are aligned in one direction. The direction in which the first portion 43d and the third portion 43f extend is perpendicular to the direction in which the second portion 43e extends.

[0084] The first part 43d is attached to the lower part of the suspension groove 30, and the first part 43d has a plurality of slits L1, L2 arranged in the longitudinal direction of the railway vehicle body 1B. The slits L1, L2 extend in the width direction of the railway vehicle body 1B, and when viewed from the vertical direction of the railway vehicle body 1B, the first part 43d has, for example, an E shape. The intermediate holding member 40D and the suspension groove 30 are fixed in the same manner as in the second embodiment. Specifically, the slits L1, L2 are inserted into fixing members such as bolts provided in the suspension groove 30 as described above, and fixing members such as nuts are screwed onto the lower part of the bolts, thereby fixing the intermediate holding member 40D (intermediate main body 43D) to the suspension groove 30. The intermediate main body 43D is detachable from the suspension groove 30 along the width direction of the railway vehicle body 1B.

[0085] When the intermediate holding member 40D is attached to the suspension groove 30, the first portion 43d is located below the suspension groove 30, the second portion 43e is located on the interior side of the railway vehicle body 1B relative to the suspension groove 30, and the third portion 43f is located above the suspension groove 30. The first portion 43d, the second portion 43e, and the third portion 43f are arranged in this order vertically in the railway vehicle body 1B. The second portion 43e and the third portion 43f are fixed to each other, for example, by fillet welding.

[0086] The intermediate projection 47 is, for example, shaped like a rectangular plate with rounded corners. The intermediate projection 47 has a first projection 47a and a second projection 47b that are flush with the third portion 43f and project outwards on both sides of the intermediate main body 43D in the width direction. When the intermediate holding member 40D is attached to the suspension groove 30, the first projection 47a projects outwards from the third portion 43f to one side of the intermediate main body 43D in the width direction, and the second projection 47b projects outwards from the third portion 43f to the other side of the intermediate main body 43D in the width direction. The width of the first projection 47a in the width direction of the intermediate main body 43D is, for example, the same as the width of the second projection 47b in the width direction of the intermediate main body 43D.

[0087] In the portion of the intermediate main body 43D where the intermediate protrusion 47 is provided, the width of the intermediate holding member 40D in the width direction of the intermediate main body 43D is equal to the combined length of the first protrusion 47a, the intermediate main body 43D, and the second protrusion 47b in the width direction of the intermediate main body 43D. In other words, in the intermediate holding member 40D, the width of the portion where the intermediate protrusion 47 is provided is wider than the width of the portion where the intermediate protrusion 47 is not provided.

[0088] The intermediate holding member 40D has a plurality of intermediate protrusions 47 aligned in the thickness direction of the second portion 43e (corresponding to the vertical direction of the railway vehicle body 1B). Between the plurality of intermediate protrusions 47, 47, a plurality of slits K1, K2 are formed aligned in the width direction of the intermediate main body 43D. The slits K1, K2 extend in the width direction of the intermediate main body 43D and are not formed in the intermediate main body 43D (third portion 43f).

[0089] In this embodiment, the intermediate main body portion 43D and the intermediate protrusion portion 47 may be integrally molded by press molding or the like. The intermediate protrusion portion 47 may be made of a separate component from the intermediate main body portion 43D. The intermediate protrusion portion 47 may be made of a separate component from the intermediate main body portion 43D so as to be detachably attached to the intermediate main body portion 43D.

[0090] When the intermediate holding member 40D is attached to the suspension groove 30, the intermediate protrusions 47 are located on the interior side of the railway vehicle body 1B relative to the suspension groove 30, and multiple intermediate protrusions 47 are arranged in the width direction of the railway vehicle body 1B. The slits K1 and K2 extend in the longitudinal direction of the railway vehicle body 1B and are arranged in the longitudinal direction of the railway vehicle body 1B.

[0091] In this modified form, the same effects as in the second embodiment can be obtained, and slits K1 and K2 are formed between the multiple intermediate protrusions 47, 47, and a wiring retention area is formed in the intermediate main body 43D, so that wiring can be fixed to the intermediate protrusions 47. Furthermore, wiring (wiring bundle) can be fixed to one intermediate protrusion 47 and another wiring (wiring bundle) can be fixed to the other intermediate protrusion 47. In this way, multiple wirings (wiring bundles) can be fixed to the intermediate protrusions 47.

[0092] [Third modified example of the intermediate holding member] Figure 11 is a perspective view showing an intermediate holding member according to a third modified example. The wiring holding structure 10E according to the third modified example differs from the wiring holding structure 10D according to the second modified example in that the intermediate holding member 40E has an intermediate protrusion 48 that is inclined with respect to the intermediate protrusion 47, in addition to the intermediate protrusion 47.

[0093] The intermediate main body portion 43E of the intermediate holding member 40E is, for example, shaped like a rectangular plate with rounded corners. The intermediate main body portion 43E is aligned along its length (corresponding to the width direction of the railway vehicle body 1B) and has a first portion 43g and a second portion 43h. The first portion 43g and the second portion 43h are aligned along the thickness direction of the intermediate main body portion 43E (corresponding to the vertical direction of the railway vehicle body 1B). One end of the first portion 43g in the length direction of the intermediate main body portion 43E is bent toward the second portion 43h. One end of the second portion 43h in the length direction of the intermediate main body portion 43E is bent toward the first portion 43g. With both bent, the first portion 43g and the second portion 43h are adjacent to each other.

[0094] One end of the first portion 43g in the longitudinal direction of the intermediate body portion 43E and one end of the second portion 43h in the longitudinal direction of the intermediate body portion 43E are fixed to each other, for example, by fillet welding. More specifically, one end of the first portion 43g in the longitudinal direction of the intermediate body portion 43E is fixed to the second portion 43h at a position offset toward the center of the intermediate body portion 43E from one end of the second portion 43h in the longitudinal direction of the intermediate body portion 43E.

[0095] The intermediate projection 48 is formed to protrude from the intermediate main body 43E (second part 43h) in the portion where the first part 43g and the second part 43h are fixed. The intermediate projection 48 protrudes from the intermediate main body 43E on both sides in the width direction of the intermediate main body 43E (corresponding to the longitudinal direction of the railway vehicle body 1B). The intermediate projection 48 is inclined in the length direction and thickness direction of the intermediate main body 43E. The intermediate projection 48 is, for example, in the shape of a rectangular plate with rounded corners.

[0096] The intermediate projection 48 has a first projection 48a and a second projection 48b. The first projection 48a protrudes from the second portion 43h to one side in the width direction of the intermediate main body 43E, and the second projection 48b protrudes from the second portion 43h to the other side in the width direction of the intermediate main body 43E. The width of the first projection 48a in the width direction of the intermediate main body 43E is, for example, the same as the width of the second projection 48b in the width direction of the intermediate main body 43E.

[0097] At the location where the intermediate protrusion 48 is provided in the intermediate main body portion 43E, the width of the intermediate retaining member 40E in the width direction of the intermediate main body portion 43E is equal to the combined length of the first protrusion 48a, the intermediate main body portion 43E, and the second protrusion 48b in the width direction of the intermediate main body portion 43E. In other words, in the intermediate retaining member 40E, the width of the portion where the intermediate protrusion 48 is provided is wider than the width of the portion where the intermediate protrusion 48 is not provided.

[0098] In this embodiment, the intermediate main body portion 43E and the intermediate protrusion portion 48 may be integrally molded by press molding or the like. The intermediate protrusion portion 48 may be made of a separate component from the intermediate main body portion 43E. The intermediate protrusion portion 48 may be made of a separate component from the intermediate main body portion 43E and be detachably attached to the intermediate main body portion 43E.

[0099] When the intermediate holding member 40E is attached to the suspension groove 30, the first portion 43g and the second portion 43h are aligned vertically with respect to the railway vehicle body 1B, with the first portion 43g located below the suspension groove 30 and the second portion 43h located above the suspension groove 30. The intermediate projection 48 is located on the side of the side structure 3 relative to the suspension groove 30 and is inclined with respect to the width and vertical directions of the railway vehicle body 1B according to the curvature of the rafter member T.

[0100] In this modified example, the intermediate protrusion 47 is formed on the second portion 43h of the intermediate main body portion 43E.

[0101] In this modified form, the same effects as in the second modified form can be obtained. Furthermore, in this modified form, at the position where the intermediate projection 48 is provided in the intermediate main body 43E, the combined length of the first projection 48a, the intermediate main body 43E, and the second projection 48b in the longitudinal direction of the railway vehicle body 1B is longer than the length of the second part 43h in the longitudinal direction of the railway vehicle body 1B. This allows both the first projection 48a and the second projection 48b to be used as holding surfaces for wiring. As a result, wiring can be fixed to the intermediate projection 48 in addition to the intermediate projection 47. Moreover, since the intermediate projection 48 is inclined with respect to the width and vertical direction of the railway vehicle body 1B, a worker can easily hold the wiring to the intermediate projection 48 by inserting their hand or tools into the space where the wiring is provided. Furthermore, since the wiring holding structure 10E has an intermediate projection 48 in addition to the intermediate projection 47, multiple types of wiring can be provided.

[0102] [Other variations] This disclosure is not limited to the embodiments described above. For example, in the embodiments described above, the protrusions 25, 26, and 27 protrude from the main body 21 to both sides in the longitudinal direction of the railway vehicle structure 1, but the protrusions 25, 26, and 27 may protrude from the main body 21 to one side in the longitudinal direction of the railway vehicle structure 1. The intermediate protrusions 45 and 46 protrude from the intermediate main body 43 to both sides in the longitudinal direction of the railway vehicle structure 1B, but the intermediate protrusions 45 and 46 may protrude from the intermediate main body 43 to one side in the longitudinal direction of the railway vehicle structure 1B.

[0103] In the above embodiment, with the holding member 20 attached to the rafter member T, the protrusions 25, 26, and 27 extend in the longitudinal direction of the railway vehicle structure 1, but the protrusions 25, 26, and 27 may also extend in the width direction of the railway vehicle structure 1. Also, in the above embodiment, the suspension groove 30 extends in the longitudinal direction of the railway vehicle structure 1 below the rafter member T, but the suspension groove 30 may also extend in the width direction of the railway vehicle structure 1.

[0104] Furthermore, in the above embodiment, when the intermediate holding member 40 is attached to the suspension groove 30, the intermediate protrusions 45 and 46 extend in the longitudinal direction of the railway vehicle body 1, but the intermediate protrusions 45 and 46 may also extend in the width direction of the railway vehicle body 1. The same applies to the intermediate protrusions 47 and 48. In this case, the direction in which the intermediate protrusions 45 to 48 extend coincides with the direction in which the protrusions 25, 26, and 27 of the holding member 20 extend.

[0105] In the above embodiment, the protruding portion 25 has a first protruding portion 25a and a second protruding portion 25b that protrude from both sides in the width direction of the main body portion 21, but the protruding portion 25 may have only one of the first protruding portion 25a and the second protruding portion 25b. The same applies to the protruding portions 26 and 27. Also, the intermediate protruding portion 45 has a first protruding portion 45a and a second protruding portion 45b that protrude from both sides in the width direction of the intermediate main body portion 43, but the intermediate protruding portion 45 may have only one of the first protruding portion 45a and the second protruding portion 45b. The same applies to the intermediate protruding portions 46, 47 and 48.

[0106] In the above embodiment, for example, the protruding portion 25 and the intermediate protruding portion 45 are, for example, rounded rectangular in shape, but the protruding portion 25 and the intermediate protruding portion 45 may also be, for example, semicircular or triangular in shape. The shape of the protruding portion 25 and the intermediate protruding portion 45 is not particularly limited.

[0107] In the above embodiment, the main body 21 has a first fixing portion 22 and a second fixing portion 23, but the main body 21 may have only the first fixing portion 22. In this case, the holding member 20 may be J-shaped when viewed from the longitudinal direction of the railway vehicle structure 1. [Explanation of Symbols]
