Description

The present invention relates to railway vehicles and manufacturing methods thereof, and more particularly to railway vehicles having mounting structures for attaching interior items such as luggage racks to the body structure, and manufacturing methods thereof.

For example, as shown in Figures 11 and 12, a side structure 100a constituting the body of a railway vehicle 100 has multiple side entrances 100b formed at predetermined intervals, side windows 100c arranged between the side entrances, and interior fittings 100d such as long luggage racks 105 arranged above the side windows. Furthermore, interior fittings 100d such as long slings 107 are arranged on the roof structure 100e constituting the body of the railway vehicle 100. For example, the luggage racks 105 are composed of multiple luggage rack brackets 105a screwed to the side inner ribs 101 and lining panels 103 constituting the side structure 100a at positions spaced apart at predetermined intervals in the fore-and-aft direction of the vehicle, and luggage rack bars 105b fixed to the luggage rack brackets 105a.

However, the side inner frame 101 and the interior panel 103 that make up the side structure 100a each have manufacturing errors, and assembly errors can also occur. Therefore, in order to install the luggage rack bracket 105a etc. in the correct position, it was necessary to perform work such as measuring the installation position correctly, marking, drilling holes, and threading the screws to match the actual vehicle to which the side inner frame 101 and the interior panel 103 were assembled. Specifically, the screw seat 102 is fixed to the outside of the assembled side inner frame 101, and then pilot holes are drilled in the assembled interior panel 103, side inner frame 101, and screw seat 102. Female screw holes 104 are then formed in the pilot holes. After that, the female screw holes 104 are aligned with the screw insertion holes 106a and 106b formed in the mounting seat 106 of the luggage shelf bracket 105a, and set screws 108 are inserted through the screw insertion holes 106a and 106b and fastened to the female screw holes 104, thereby attaching the luggage shelf bracket 105a to the side inner frame 101 and interior panel 103 in the correct position.

However, with the above-mentioned luggage rack 105 mounting structure, the screw seat 102 fixed to the outer side of the vehicle body of the inner side frame 101 is not visible to the worker, making it difficult to determine the position of the screw seat, which required the screw seat 102 to be made larger than necessary, which was structurally undesirable. Furthermore, because the luggage rack 105 is mounted high, there is a problem that workers have to work upwards frequently, which places a heavy burden on them. Furthermore, drilling, female threading, etc. generates a lot of chips, which must be carefully cleaned up after the work, which increases the work time.

To address this issue, for example, Patent Document 1 discloses a technology in which, as shown in Figures 13 and 14, screw insertion holes 201a, 202a are provided in overlapping relation in an interior panel 201 and a side inner frame 202 disposed on the outside of the vehicle body of the interior panel 201, and screw insertion holes 203a of an interior part 203 (luggage shelf bracket) are aligned with the screw insertion holes 201a, 202a, and set screws 204 inserted from the interior part side into these screw insertion holes 201a, 202a, 203a are inserted. In a railway vehicle interior fitting mounting structure in which interior fittings 203 are attached by screwing into female threaded holes 205a in screw seats 205 attached to the outer surface of the side inner frame 202, a configuration is disclosed in which at least the screw insertion holes 201a, 202a in the interior panel 201 and the side inner frame 202 are formed with a larger diameter than the female threaded hole 205a, a guide frame 206 is provided on the outer surface of the side inner frame 202, and the screw seat 205 is slidably supported within the guide frame 206. This configuration eliminates the need for work such as drilling holes and machining female threads to fit the actual vehicle, and avoids the generation of chips.

Japanese Patent Application Laid-Open No. 2002-356162

However, with the railway vehicle interior fitting mounting structure described in Patent Document 1, the screw insertion hole 201a in the interior panel 201 is hidden by the interior fitting 203, making it difficult for workers to see. This poses a problem: the screw insertion hole 203a in the interior fitting 203 must be aligned with the screw insertion holes 201a, 202a in the interior panel 201 and side inner frame 202, and the set screw 204 must be inserted into these screw insertion holes 201a, 202a, 203a from the interior fitting side, and then the inserted set screw 204 must be fastened into the female screw hole 205a, which requires a lot of work.

Furthermore, the screw insertion holes 201a, 202a of at least the interior panel 201 and the side inner frame 202 are formed with a larger diameter than the female screw hole 205a, a guide frame 206 is provided on the outer surface of the carbody of the side inner frame 202, and the screw seat 205 is slidably supported within the guide frame 206. Therefore, by sliding the screw seat 205 within the guide frame 206, it is possible to adjust the mounting position of the interior equipment 203 in the fore-and-aft direction of the car (towards the rails) and the up-and-down direction of the car (towards the vehicle height), but it is not possible to adjust it in the left-and-right direction of the car (towards the sleepers). In other words, manufacturing and assembly errors in the structure that makes up the railway car can occur in all directions (three-dimensional directions), including fore-and-aft, up-and-down, and left-and-right, and there was a problem in that it was not easy to absorb these manufacturing errors and adjust the mounting position of the interior equipment to the correct position.

The present invention was made to solve these problems, and aims to provide a railway vehicle with an interior accessory mounting structure and a manufacturing method thereof that eliminates the need for work such as drilling holes and threading the body structure to fit the actual vehicle, speeds up screw fastening work, and allows the mounting position relative to the body structure to be easily adjusted in any direction, including front-to-back, up-down, and left-to-right.

In order to achieve the above object, a railway vehicle and a manufacturing method thereof according to the present invention have the following configuration.
(1) A railway vehicle having an interior fitting mounting structure to be attached to the inside of the car body of a body structure,
The mounting structure includes a fixing bolt fixed to the body structure and having a male thread portion protruding toward the inside of the vehicle body, a support plate inserted through the male thread portion of the fixing bolt from the inside of the vehicle body and formed so that an attachment position relative to the fixing bolt can be moved in a first direction along the attachment surface of the body structure, and a movable bolt supported by the support plate so as to be movable in a second direction perpendicular to the first direction and along the attachment surface of the body structure, and having a male thread portion for attaching a mounting seat for the interior part protruding from the support plate toward the inside of the vehicle body,
The interior part is fastened to the support plate via the movable bolt, and the support plate is fastened to the body structure via the fixing bolt.

In this invention, the mounting structure includes a fixing bolt fixed to the body structure and having a male threaded portion protruding toward the inside of the car body; a backing plate inserted through the male threaded portion of the fixing bolt from the inside of the car body so that its mounting position relative to the fixing bolt can be moved in a first direction along the mounting surface of the car body; and a movable bolt supported on the backing plate so that it can move in a second direction perpendicular to the first direction and along the mounting surface of the car body, and whose male threaded portion protrudes from the backing plate toward the inside of the car body to attach a mounting seat for the interior part. The interior part is fastened to the backing plate via the movable bolt, and the backing plate is fastened to the body structure via the fixing bolt. Therefore, the mounting position of the backing plate relative to the fixing bolt fixed to the body structure can be adjusted by moving the backing plate in the first direction along the mounting surface of the car body, and the mounting position of the interior part relative to the backing plate can be adjusted by moving the movable bolt in a second direction perpendicular to the first direction and along the mounting surface of the car body. Furthermore, the mounting position of the interior part relative to the body structure can be adjusted in a third direction perpendicular to the first and second directions by adjusting the thickness of the backing plate. This allows the mounting position of interior accessories relative to the body structure to be easily adjusted in any direction, including front-to-back, up-down, left-to-right, and so on.

In addition, the mounting position of the interior parts relative to the body structure can be easily adjusted in any direction, including front-to-back, up-down, and left-to-right, eliminating the need for work such as drilling holes and threading the body structure to fit the actual vehicle. Furthermore, the interior parts are fastened to the backing plate via movable bolts whose male threads protrude inside the car body, and the backing plate is fastened to the body structure via fixed bolts whose male threads protrude inside the car body. This allows workers to fasten the interior parts to the backing plate while checking the male threads of the movable bolts that protrude from the backing plate inside the car body, and to fasten the backing plate to the body structure while checking the male threads of the fixed bolts that protrude from the body structure inside the car body. This allows for smoother and faster screw fastening of the interior parts to the backing plate and the backing plate to the body structure.

The present invention therefore makes it possible to provide a railway vehicle with an interior accessory mounting structure that eliminates the need for drilling holes in the body structure to fit the actual vehicle, machining female screws, and other work, speeds up screw fastening work, and allows the mounting position relative to the body structure to be easily adjusted in any direction, including front-to-back, up-down, and left-to-right.

(2) In the railway vehicle described in (1),
A thickness adjusting liner is mounted between the mounting surface of the body structure and the mounting seat of the interior equipment.

In this invention, a thickness-adjusting liner is attached between the mounting surface of the body structure and the mounting seat of the interior part. This makes it easier to adjust the mounting position of the interior part relative to the body structure in the direction perpendicular to the mounting surface of the body structure by adjusting the thickness of the thickness-adjusting liner. This makes it even easier to adjust the mounting position of the interior part relative to the body structure in any direction, including front-to-back, up-down, and left-to-right.

(3) In the railway vehicle described in (1) or (2),
the support plate comprises a first support plate arranged on the mounting surface side of the body structure and a second support plate arranged on the mounting seat side of the interior part,
The first receiving plate is formed with a guide hole that supports the head of the movable bolt so that it cannot rotate while guiding it in a second direction, and the second receiving plate is formed with a screw insertion hole that inserts the male threaded portion of the movable bolt so that it can move in the second direction.

In this invention, the backing plate comprises a first backing plate arranged on the mounting surface side of the bodywork and a second backing plate arranged on the mounting seat side of the interior part. The first backing plate has a guide hole formed therein that non-rotatably supports the head of the movable bolt while guiding it in the second direction, and the second backing plate has a screw insertion hole formed therein through which the male threaded portion of the movable bolt is inserted so that it can move in the second direction. Therefore, by dividing the backing plate into a first backing plate with a guide hole formed therein that non-rotatably supports the head of the movable bolt while guiding it in the second direction and a second backing plate with a screw insertion hole formed therein through which the male threaded portion of the movable bolt is inserted so that it can move in the second direction, it is possible to more easily form the support structure for the movable bolt relative to the backing plate.

In other words, the first backing plate can be formed with a guide hole passing through it, and the second backing plate can be formed with a screw insertion hole passing through it, so two types of hole drilling can be performed separately on the first and second backing plates. This makes it easier to form the support structure for the movable bolt relative to the backing plate. Furthermore, the first backing plate is formed with a guide hole that supports the head of the movable bolt so that it cannot rotate and guides it in the second direction. Therefore, when fastening an interior part to the second backing plate via the movable bolt, the guide hole prevents the movable bolt from rotating, reducing the effort required for screw fastening.

(4) In the railway vehicle described in (3),
the interior equipment is a luggage rack equipped with a luggage rack bracket attached to a mounting plate fixed to the inside of the car body of the side inner frame of the side structure, the fixing bolt is fixed to the mounting plate, and the mounting seat of the luggage rack bracket is fastened to the movable bolt;
The second support plate is formed so that the bracket main body extending from the mounting seat of the luggage rack bracket toward the inside of the vehicle body can be exposed, and the lower end of the side ceiling panel formed so that it can shield the mounting seat of the luggage rack bracket and the inspection window formed in the side structure is fastened to it in an adjustable mounting position.

In this invention, the interior accessory is a luggage rack equipped with a luggage rack bracket attached to a mounting plate fixed to the inside of the car body of the side inner frame of the side structure. The fixing bolt is fixed to the mounting plate, and the mounting seat of the luggage rack bracket is fastened to the movable bolt. Therefore, the mounting position of the first and second support plates relative to the fixing bolt fixed to the mounting plate of the side structure can be adjusted by moving the first and second support plates in a first direction along the mounting surface of the mounting plate, and the mounting position of the luggage rack bracket relative to the first and second support plates can be adjusted by moving the movable bolt in a second direction perpendicular to the first direction and along the mounting surface of the mounting plate. In addition, the mounting position of the luggage rack bracket relative to the mounting plate can be adjusted in a third direction perpendicular to the first and second directions by adjusting the plate thickness of the first and/or second support plate. Therefore, the mounting position of the luggage rack relative to the side structure can be easily adjusted in any direction, including fore-aft, up-down, and left-right, of the vehicle.

The second support plate is formed to expose the bracket body, which extends from the mounting seat of the luggage rack bracket toward the inside of the car body, and the lower end of the side ceiling panel, which is formed to shield the mounting seat of the luggage rack bracket and the inspection window formed in the side structure, is fastened to it so that its mounting position can be adjusted. Therefore, by removing the lower end of the side ceiling panel from the second support plate, the mounting position of the luggage rack relative to the side structure can be adjusted, and by attaching the lower end of the side ceiling panel to the second support plate, the mounting seat of the luggage rack bracket is hidden, improving the appearance of the luggage rack to passengers.

In addition, the lower end of the side ceiling panel, which is designed to be able to cover the inspection window formed in the side structure, is fastened to the second support plate in an adjustable mounting position, eliminating the need to provide a separate cover for the inspection window; the side ceiling panel can also serve as a cover for the inspection window. Furthermore, because the side ceiling panel is fastened to the second support plate in an adjustable mounting position, when the mounting position of the second support plate relative to the side structure is adjusted, the mounting position of the side ceiling panel relative to the second support plate can be adjusted in accordance with the amount of adjustment.

(5) In the railway vehicle described in (4),
The upper end of the side ceiling panel is characterized by having an elastic engagement portion that clamps and engages a spring-shaped engaging member that is attached to a hanging hardware attached to the roof structure so that the mounting position can be adjusted.

In this invention, the upper end of the side ceiling panel is equipped with an elastic engagement portion that clamps and engages a spring-shaped interlocking member that is attached to a hanging hardware attached to the roof structure in an adjustable mounting position. This allows the lower end of the side ceiling panel to be removed from the second support plate while the upper end of the side ceiling panel is attached to the hanging hardware of the roof structure, while absorbing manufacturing errors, etc. of the roof structure. Then, by elastically deforming the spring-shaped interlocking member that engages with the elastic engagement portion, or by disengaging the elastic engagement portion from the spring-shaped interlocking member, the side ceiling panel can be separated from the inspection window formed in the side structure, allowing easy inspection of the equipment inside the inspection window.

(6) A method for manufacturing a railway vehicle according to (1) or (2),
a temporary fixing step of temporarily fixing the interior part to the receiving plate via the movable bolt;
a temporary fixing process of temporarily fixing the support plate to which the interior part has been temporarily fixed to the body structure via the fixing bolts;
and an adjusting step of moving and adjusting the mounting position of the temporarily fixed interior part to a normal position relative to the body structure.

This invention includes a temporary fixing process in which the interior part is temporarily fixed to the receiving plate using movable bolts, and a temporary fixing process in which the receiving plate with the temporarily fixed interior part is temporarily fixed to the body structure using fixing bolts. Therefore, by temporarily fixing the interior part to the receiving plate in the temporary fixing process, and then temporarily fixing the receiving plate with the temporarily fixed interior part to the body structure in the temporary fixing process, the interior part can be quickly attached to the body structure.

In addition, the system includes an adjustment process for moving and adjusting the mounting position of the temporarily fixed interior part to the correct position relative to the body structure, so the mounting position of the interior part can be moved and adjusted to the correct position relative to the body structure while the interior part and support plate are temporarily fixed to the body structure. This eliminates the need for work such as drilling holes and threading to fit the actual vehicle, and there is no need to support the interior part using a support jig, etc., allowing the mounting position of the interior part to be easily and quickly moved and adjusted to the correct position relative to the body structure.

The present invention provides a railway vehicle and manufacturing method that has an interior accessory mounting structure that eliminates the need for drilling holes and threading the body structure to fit the actual vehicle, speeds up screw fastening work, and allows the mounting position to be easily adjusted in any direction, including front-to-back, up-down, and left-to-right.

Specifically, after providing a detailed description of the interior accessory mounting structure for a railway vehicle according to this embodiment, a manufacturing method for this railway vehicle according to another embodiment will be described.

<Interior equipment mounting structure for this railway vehicle>
First, the mounting structure for interior accessories in a railway vehicle will be described with reference to Figures 1 to 9. Figure 1 shows a partial side view of the interior of a railway vehicle body representing one aspect of this embodiment. Figure 2 shows a perspective view of the mounting structure for interior accessories in a railway vehicle at section A shown in Figure 1.

Figure 7 shows an exploded perspective view of the mounting structure for a side ceiling panel shown in Figure 6. Figure 8 shows a partial cross-sectional view of section D shown in Figure 6. Figure 9 shows a partial cross-sectional view of section E shown in Figure 6.

As shown in Figures 1 to 9, a railway vehicle 10 representing one aspect of this embodiment is a railway vehicle 10 having a mounting structure 3 for an interior fitting 2 attached to the inside of the carbody of the body structure 1. Here, the body structure 1 refers to the side body structure 1G, roof body structure 5, etc. that make up the body of the railway vehicle 10. The interior fitting 2 refers to equipment attached to the interior side of the carbody, such as a luggage rack or a hanging device. The interior fitting 2 is preferably an elongated object that is susceptible to manufacturing errors and assembly errors in the body structure 1.

As shown in Figures 2 to 4, the mounting structure 3 includes a fixing bolt 31 fixed to the body structure 1 with a male thread portion 31a protruding toward the inside of the car body; a support plate 32 inserted through the male thread portion 31a of the fixing bolt 31 from the inside of the car body and formed so that its mounting position relative to the fixing bolt 31 can be moved in a first direction (direction of arrow P1) along the mounting surface 11 of the body structure 1; and a movable bolt 33 supported by the support plate 32 and movable in a second direction (direction of arrow P2) perpendicular to the first direction and along the mounting surface 11 of the body structure 1, with a male thread portion 33a protruding from the support plate 32 toward the inside of the car body for attaching the mounting seat 21 of the interior part 2. The interior part 2 is fastened to the support plate 32 via the movable bolt 33, and the support plate 32 is fastened to the body structure 1 via the fixing bolt 31.

Here, the fixing bolts 31 are fixed to a mounting plate 11G arranged inside the vehicle body of the side inner frame 12G, which is the reinforcing frame of the side structure 1G. The heads (base ends) of multiple (e.g., four) fixing bolts 31 are embedded and fixed in the mounting plate 11G, and the male thread portion 31a of each fixing bolt 31 protrudes in the direction perpendicular to the mounting surface 11 (in the direction of arrow P3). Note that the mounting plate 11G does not have to be limited to a rectangular dedicated plate formed for fixing the fixing bolts 31; for example, it could be a door pocket panel arranged adjacent to a side entrance.

The support plate 32 is composed of a first support plate 32A arranged on the mounting surface 11 side of the body structure 1 and a second support plate 32B arranged on the mounting seat 21 side of the interior part 2. The first support plate 32A and the second support plate 32B have elongated screw insertion holes 324, 325 of the same shape and at the same position, through which the male threaded portion 31a of the fixing bolt 31 can be inserted and which can move in the first direction (the direction of arrow P1). In one aspect of this embodiment, the first support plate 32A and the second support plate 32B are separate bodies, but the first support plate 32A and the second support plate 32B may also be formed integrally. The mounting seat 21 of the interior part 2 has multiple (e.g., four) screw insertion holes 211 formed therein through which the male threaded portion 33a of the movable bolt 33 can be inserted.

With the above configuration, the attachment position of the support plate 32 relative to the fixing bolt 31 fixed to the body structure 1 can be adjusted by moving the support plate 32 in a first direction along the body structure 1's mounting surface 11, and the attachment position of the interior part 2 relative to the support plate 32 can be adjusted by moving the movable bolt 33 in a second direction perpendicular to the first direction and along the body structure 1's mounting surface 11. Furthermore, by adjusting the plate thickness of the support plate 32, the attachment position of the interior part 2 relative to the body structure 1 can be adjusted in a third direction (the direction of arrow P3) perpendicular to the first and second directions. Here, the first direction corresponds to the vehicle's up-down direction, the second direction corresponds to the vehicle's fore-aft direction, and the third direction corresponds to the vehicle's left-right direction. Therefore, the attachment position of the interior part 2 relative to the body structure 1 can be easily adjusted in any direction, including fore-aft, up-down, and left-right.

Furthermore, because the mounting position of the interior accessory 2 relative to the body structure 1 can be easily adjusted in any direction, including front-to-rear, up-down, and left-to-right, the need for drilling holes and threading the body structure 1 to fit the actual vehicle is eliminated. Furthermore, the interior accessory 2 is fastened to the backing plate 32 via a movable bolt 33 whose male thread portion 33a protrudes toward the inside of the car body, and the backing plate 32 is fastened to the body structure 1 via a fixing bolt 31 whose male thread portion 31a protrudes toward the inside of the car body. This allows workers to fasten the interior accessory 2 to the backing plate 32 while checking the male thread portion 33a of the movable bolt 33 protruding from the backing plate 32 toward the inside of the car body, and fasten the backing plate 32 to the body structure 1 while checking the male thread portion 31a of the fixing bolt 31 protruding from the body structure 1 toward the inside of the car body. This allows for smoother and faster screw fastening of the interior accessory 2 to the backing plate 32 and screw fastening of the backing plate 32 to the body structure 1.

Therefore, with the railway vehicle 10 according to this embodiment, it is possible to eliminate the need for work such as drilling holes and threading the body structure 1 to fit the actual vehicle, and it is also possible to speed up the screw fastening work, thereby providing a railway vehicle 10 having an interior fitting 2 mounting structure 3 that allows the mounting position of the interior fitting 2 relative to the body structure 1 to be easily adjusted in any direction, including front-to-rear, up-down, and left-to-right.

In addition, in the railway vehicle 10 according to this embodiment, a thickness-adjusting liner 34 is preferably installed between the mounting surface 11 of the body structure 1 and the mounting seat 21 of the interior fitting 2. Here, the thickness-adjusting liner 34 is formed between the receiving plate 32 (second receiving plate 32B) and the mounting seats 21, 21B of the interior fittings 2, 2B, with a size approximately the same as the mounting seats 21, 21B of the interior fittings 2, 2B, and has a predetermined thickness that can absorb manufacturing errors of the body structure 1. The thickness-adjusting liner 34 has a screw insertion hole 341 through which the male thread portion 33a of the movable bolt 33 can be inserted. Note that multiple thickness-adjusting liners 34 with different thicknesses may be prepared, and a suitable one may be selected from these, or multiple liners may be combined to achieve the desired thickness. The thickness-adjusting liner 34 may also be installed between the mounting surface 11 of the body structure 1 and the receiving plate 32 (first receiving plate 32A). In this case, a screw insertion hole of approximately the same size as the first receiving plate 32A is formed in the plate thickness adjustment liner 34, through which the male threaded portion 31a of the fixing bolt 31 can be inserted.

With the above configuration, the mounting position of the interior part 2 relative to the body structure 1 can be more easily adjusted in the direction perpendicular to the mounting surface 11 of the body structure 1 (the direction of arrow P3) by adjusting the thickness of the thickness-adjusting liner 34. This makes it even easier to adjust the mounting position of the interior part 2 relative to the body structure 1 in any direction, including front-to-rear, up-down, and left-to-right, of the vehicle.

In addition, in the railway vehicle 10 according to this embodiment, the support plate 32 comprises a first support plate 32A arranged on the mounting surface 11 side of the body structure 1 and a second support plate 32B arranged on the mounting seat 21 side of the interior part 2. Preferably, the first support plate 32A is formed with a guide hole 321 that supports the head 33b of the movable bolt 33 non-rotatably while guiding it in the second direction (the direction of arrow P2), and the second support plate 32B is formed with a screw insertion hole 322 that passes through the male threaded portion 33a of the movable bolt 33 so that it can move in the second direction.

The first support plate 32A has two rectangular guide holes 321 extending parallel to each other in the second direction (the direction of arrow P2) at positions spaced apart by the hole pitch in the first direction (the direction of arrow P1) of the screw insertion holes 211 formed in the mounting seat 21 of the interior part 2. The heads 33b of two movable bolts 33 are inserted into the two guide holes 321, respectively, so that they can move in the second direction. The heads 33b of each movable bolt 33 are formed in a roughly square shape, and the outer edge of the head 33b is formed to be able to slide against the inner edge of the guide hole 321. The four movable bolts 33 are formed separately to facilitate forging; however, for example, the heads 33b of two movable bolts 33 attached to the same guide hole 321 may be formed integrally. In this case, the distance of the sliding contact area where the outer edge of the head 33b and the inner edge of the guide hole 321 come into sliding contact is increased, more reliably preventing rotation of the head when the movable bolt 33 is tightened.

With the above configuration, by dividing the receiving plate 32 into a first receiving plate 32A formed with a guide hole 321 that non-rotatably supports the head 33b of the movable bolt 33 while guiding it in the second direction, and a second receiving plate 32B formed with a screw insertion hole 322 that allows the male threaded portion 33a of the movable bolt 33 to be inserted movably in the second direction, the support structure for the movable bolt 33 relative to the receiving plate 32 can be more easily formed.

In other words, because the first receiving plate 32A can be formed with the guide hole 321 penetrating it, and the second receiving plate 32B can be formed with the screw insertion hole 322 penetrating it, two types of hole drilling can be performed separately on the first receiving plate 32A and the second receiving plate 32B. This makes it easier to form the support structure for the movable bolt 33 relative to the receiving plate 32. Furthermore, the first receiving plate 32A is formed with the guide hole 321 that guides the head 33b of the movable bolt 33 in the second direction (the direction of arrow P2) while supporting it so that it cannot rotate. Therefore, when fastening the interior part 2 to the second receiving plate 32B via the movable bolt 33, the guide hole 321 can prevent the movable bolt 33 from rotating without holding the head 33b of the movable bolt 33, and this reduces the effort required for the screw fastening work.

Furthermore, in the railway vehicle 10 according to this embodiment, the interior equipment 2 is a luggage rack 2B equipped with a luggage rack bracket 22B attached to the mounting plate 11G of the side structure 1G, and it is preferable that the fixing bolt 31 is fixed to the mounting plate 11G and the mounting seat 21B of the luggage rack bracket 22B is fastened to the movable bolt 33.

In this mounting structure 3B for the luggage shelf 2B, the mounting positions of the first and second support plates 32A and 32B relative to the fixing bolts 31 secured to the mounting plate 11G of the side structure 1G can be adjusted by moving the first and second support plates 32A and 32B in a first direction (indicated by arrow P1) along the mounting surface 11 of the mounting plate 11G. The mounting position of the luggage shelf bracket 22B relative to the first and second support plates 32A and 32B can be adjusted by moving the movable bolt 33 in a second direction (indicated by arrow P2) perpendicular to the first direction and along the mounting surface 11 of the mounting plate 11G. Furthermore, the mounting position of the luggage shelf bracket 22B relative to the mounting plate 11G can be adjusted in a third direction (indicated by arrow P3), perpendicular to the first and second directions, by adjusting the thickness of the first and/or second support plates 32A and/or 32B. This allows the mounting position of the luggage rack 2B relative to the side structure 1G to be easily adjusted in any direction, including front-to-back, up-down, left-to-right, and so on.

As shown in Figures 2, 3, 6, and 7, the second support plate 32B is preferably fastened to the lower end 42 of the side ceiling panel 4, which is formed so that the bracket main body 22BH, which extends from the mounting seat 21B of the luggage rack bracket 22B toward the inside of the car body, can be exposed, and which is formed so that the mounting seat 21B of the luggage rack bracket 22B can be shielded from the inspection window 1M formed in the side structure 1G, so that the mounting position can be adjusted. The side ceiling panel 4 has a cutout 43 formed along the outer edge of the bracket main body 22BH. The inspection window 1M may be an inspection window for the side door drive mechanism or a destination indicator light, etc.

As shown in FIG. 3 , a substantially L-shaped mounting bracket 327 that is movable in the second direction (arrow P2 direction) is attached to the lower end side 323 of the second support plate 32B. A female thread 327Z is fixed to the mounting bracket 327 and engages with a set screw 329 that fastens the lower end 42 of the side ceiling panel 4 from the first direction (arrow P1 direction). The mounting position of the lower end 42 of the side ceiling panel 4 relative to the second support plate 32B is adjusted in the third direction by a first adjusting liner 326 attached between the second support plate 32B and the mounting bracket 327, and adjusted in the first direction by a second adjusting liner 328 attached between the mounting bracket 327 and the lower end 42 of the side ceiling panel 4. Therefore, the mounting position of the lower end 42 of the side ceiling panel 4 relative to the support plate 32 can be adjusted in any direction, including front-to-rear, up-down, and left-to-right, of the vehicle.

As shown in FIG. 5, the mounting bracket 327 includes a cover 327X that accommodates the female threaded portion 327Y that engages with the set screw 329, allowing it to move in the second direction (the direction of arrow P2) and the third direction (the direction of arrow P3), making the first adjustment liner 326 unnecessary. As shown in FIG. 8, a retaining bracket 329b and a fall prevention bracket 329c for the set screw 329 are attached to the lower end 42 of the side ceiling panel 4 to prevent the set screw 329 from falling. The mounting bracket 327 also has an elongated screw insertion hole 327a that allows it to move in the second direction relative to the set screw 330 fastened to the second receiving plate 32B. However, the screw insertion hole 327a may also be elongated in the first direction. In this case, the second adjustment liner 328 may be unnecessary.

With the above configuration, the mounting position of the luggage rack 2B relative to the side structure 1G can be adjusted in any direction by disengaging the push screw 329 from the female threads 327Y, 327Z and removing the lower end 42 of the side ceiling panel 4 from the second support plate 32B. At the same time, by tightening the push screw 329 into the female threads 327Y, 327Z and attaching the lower end 42 of the side ceiling panel 4 to the second support plate 32B, the mounting base 21B of the luggage rack bracket 22B is hidden, improving the appearance of the luggage rack 2B to passengers.

In addition, the lower end 42 of the side ceiling panel 4, which is designed to be able to cover the inspection window 1M formed in the side structure 1G, is fastened to the second support plate 32B in an adjustable mounting position, eliminating the need to provide a separate cover for the inspection window 1M; the side ceiling panel 4 can also serve as a cover for the inspection window 1M. Furthermore, because the lower end 42 of the side ceiling panel 4 is fastened to the second support plate 32B in an adjustable mounting position, when the mounting position of the second support plate 32B relative to the side structure 1G is adjusted, the mounting position of the side ceiling panel 4 relative to the second support plate 32B can be adjusted in accordance with the amount of adjustment.

Furthermore, as shown in Figures 6, 7, and 9, in the railway vehicle 10 according to this embodiment, the upper end 41 of the side ceiling panel 4 is preferably provided with an elastic engagement portion 411 that clamps and engages with a spring-shaped interlocking member 52 that is attached to a hanging hardware 51 attached to the roof structure 5 so that the attachment position can be adjusted.

The hanging bracket 51 has an opening with a generally U-shaped cross section formed along the second direction, allowing the male threaded portion of the hanging screw 54 to protrude downward (first direction: direction of arrow P1) from the vehicle, and a spring-shaped interlocked member 52, whose tip extends in the first direction, is fastened by the hanging screw 54 so as to be movable in the second direction. A third adjustment liner 53 is attached between the hanging bracket 51 and the base end of the spring-shaped interlocked member 52. The elastic engagement portion 411 also has a first engagement plate 411a formed in a V-shape and a second engagement plate 411b formed in a flat plate to clamp the tip of the spring-shaped interlocked member 52.

With the above configuration, the lower end 42 of the side ceiling panel 4 can be removed from the second support plate 32B while the upper end 41 of the side ceiling panel 4 is attached to the hanging hardware 51 of the roof structure 5 in the correct position, while absorbing manufacturing errors in the roof structure 5. Then, by elastically deforming the spring-like interlocking member 52 that engages with the elastic interlocking portion 411, or by disengaging the elastic interlocking portion 411 from the spring-like interlocking member 52, the side ceiling panel 4 can be separated from the inspection window 1M formed in the side structure 1G, allowing easy inspection of the equipment inside the inspection window 1M.

<Manufacturing method of this railway vehicle>
Next, a manufacturing method of the railway vehicle 10 according to this embodiment will be described with reference to Figures 2, 3, and 10. Figure 10 shows a flowchart of the manufacturing process for the railway vehicle shown in Figure 1.

As shown in Figures 2, 3, and 10, the manufacturing method for the railway vehicle 10 includes a temporary fixing process S1 in which an interior item 2 (e.g., a luggage rack 2B) is temporarily fixed to a support plate 32 (e.g., a first support plate 32A or a second support plate 32B) via a movable bolt 33; a temporary fixing process S2 in which the support plate 32 to which the interior item 2 has been temporarily fixed is temporarily fixed to the body structure 1 (e.g., a side body structure 1G) via fixing bolts 31; and an adjustment process S3 in which the mounting position of the temporarily fixed interior item 2 is moved and adjusted to the correct position relative to the body structure 1.

That is, the system includes a temporary fixing process S1 in which the interior parts 2, 2B are temporarily fixed to the receiving plate 32 (32A, 32B) using the movable bolts 33, and a temporary fixing process S2 in which the receiving plate 32 (32A, 32B) with the interior parts 2, 2B temporarily fixed thereto is temporarily fixed to the body structure 1, 1G using the fixing bolts 31. Therefore, by temporarily fixing the interior parts 2, 2B to the receiving plate 32 (32A, 32B) in the temporary fixing process S1, and then temporarily fixing the receiving plate 32 (32A, 32B) with the interior parts 2, 2B temporarily fixed thereto to the body structure 1, 1G in the temporary fixing process S2, the interior parts 2, 2B can be quickly attached to the body structure 1, 1G.

In addition, the system includes an adjustment process S3 in which the mounting positions of the temporarily fixed interior components 2, 2B are moved and adjusted to their correct positions relative to the body structure 1, 1G. This allows the mounting positions of the interior components 2, 2B to be moved and adjusted to their correct positions relative to the body structure 1, 1G while the interior components 2, 2B and the support plate 32 (32A, 32B) are temporarily fixed to the body structure 1, 1G. This eliminates the need for work such as drilling holes and threading female screws to fit the actual vehicle, and eliminates the need to support the interior components 2, 2B using a support jig or the like. This allows the mounting positions of the interior components 2, 2B to be easily and quickly moved and adjusted to their correct positions relative to the body structure 1, 1G.

Therefore, the manufacturing method for a railway vehicle 10 according to this other embodiment eliminates the need for work such as drilling holes and threading the body structure 1, 1G to fit the actual vehicle, speeds up screw fastening work, and provides a manufacturing method for a railway vehicle 10 having mounting structures 3, 3B for interior fittings 2, 2B that can be easily adjusted in any direction, including front-to-rear, up-down, and left-to-right, on the vehicle.

<Action and effect>
According to the railway vehicle 10 according to the present embodiment described above in detail, the mounting structures 3, 3B include: a fixing bolt 31 fixed to the body structure 1 and having a male screw portion 31a protruding toward the inside of the car body; a receiving plate 32 (32A, 32B) inserted into the male screw portion 31a of the fixing bolt 31 from the inside of the car body and formed so that the mounting position relative to the fixing bolt 31 can be moved in a first direction (direction of arrow P1) along the mounting surface 11 of the body structure 1; and a receiving plate 32 (32A, 32B) supported by the receiving plate 32 (32A, 32B) so as to be movable in a second direction (direction of arrow P2) perpendicular to the first direction and along the mounting surface 11 of the body structure 1, and having a male screw portion 33a for attaching the mounting seats 21, 21B of the interior parts 2, 2B. The interior equipment 2, 2B is fastened to the receiving plates 32 (32A, 32B) via the movable bolts 33, and the receiving plates 32 (32A, 32B) are fastened to the body structure 1 via the fixing bolts 31. Therefore, the attachment positions of the receiving plates 32 (32A, 32B) relative to the fixing bolts 31 fixed to the body structure 1 can be adjusted by moving the receiving plates 32 (32A, 32B) in a first direction along the attachment surface 11 of the body structure 1, and the attachment positions of the interior equipment 2, 2B relative to the receiving plates 32 (32A, 32B) can be adjusted by moving the movable bolts 33 in a second direction perpendicular to the first direction and along the attachment surface 11 of the body structure 1. Furthermore, by adjusting the plate thickness of the receiving plate 32 (32A, 32B), the attachment positions of the interior parts 2, 2B relative to the body structure 1 can be adjusted in a third direction (the direction perpendicular to the surface of the attachment surface 11: the direction of arrow P3) that is perpendicular to the first and second directions. Therefore, the attachment positions of the interior parts 2, 2B relative to the body structure 1 can be easily adjusted in any direction, including the front-rear, up-down, and left-right directions of the vehicle.

Furthermore, because the mounting positions of the interior fittings 2, 2B relative to the body structure 1 can be easily adjusted in any direction, including front-to-rear, up-down, and left-to-right, this eliminates the need for work such as drilling holes and threading the body structure 1 to fit the actual vehicle. Furthermore, the interior fittings 2, 2B are fastened to the receiving plates 32 (32A, 32B) via movable bolts 33 whose male threads 33a protrude toward the inside of the car body, and the receiving plates 32 (32A, 32B) are fastened to the body structure 1 via fixing bolts 31 whose male threads 31a protrude toward the inside of the car body. This allows workers to fasten the interior fittings 2, 2B to the receiving plates 32 (32A, 32B) while checking the male threads 33a of the movable bolts 33 that protrude from the receiving plates 32 (32A, 32B) toward the inside of the car body, and fasten the receiving plates 32 (32A, 32B) to the body structure 1 while checking the male threads 31a of the fixing bolts 31 that protrude from the body structure 1 toward the inside of the car body. This allows for smooth and rapid screw fastening of the interior components 2, 2B to the support plates 32 (32A, 32B), and screw fastening of the support plates 32 (32A, 32B) to the body structure 1.

Accordingly, this embodiment eliminates the need for drilling holes and threading the body structure 1 to fit the actual vehicle, speeds up screw fastening work, and provides a railway vehicle 10 equipped with mounting structures 3, 3B for interior components 2, 2B whose mounting positions relative to the body structure 1 can be easily adjusted in any direction, including front-to-rear, up-down, and left-to-right.

In addition, according to this embodiment, a thickness-adjusting liner 34 is attached between the mounting surface 11 of the body structure 1 and the mounting seats 21, 21B of the interior fittings 2, 2B. This makes it easier to adjust the mounting positions of the interior fittings 2, 2B relative to the body structure 1 in the direction perpendicular to the mounting surface 11 of the body structure 1 (the direction of arrow P3) by adjusting the thickness of the thickness-adjusting liner 34. This makes it even easier to adjust the mounting positions of the interior fittings 2, 2B relative to the body structure 1 in any direction, including front-to-rear, up-down, and left-to-right.

In addition, according to this embodiment, the receiving plate 32 is composed of a first receiving plate 32A arranged on the mounting surface 11 side of the body structure 1 and a second receiving plate 32B arranged on the mounting seats 21, 21B side of the interior parts 2, 2B. The first receiving plate 32A is formed with a guide hole 321 that supports the head 33b of the movable bolt 33 so that it cannot rotate and guides it in the second direction (the direction of arrow P2). The second receiving plate 32B is formed with a guide hole 321 that supports the male threaded portion 33a of the movable bolt 33 so that it can move in the second direction. By dividing the receiving plate 32 into a first receiving plate 32A with a guide hole 321 that supports the head 33b of the movable bolt 33 non-rotatably while guiding it in the second direction, and a second receiving plate 32B with a screw insertion hole 322 that passes through the male threaded portion 33a of the movable bolt 33 so that it can move in the second direction, the support structure for the movable bolt 33 relative to the receiving plate 32 can be more easily formed.

In other words, because the first receiving plate 32A can be formed with the guide hole 321 penetrating it, and the second receiving plate 32B can be formed with the screw insertion hole 322 penetrating it, two types of hole drilling can be performed separately on the first receiving plate 32A and the second receiving plate 32B. This makes it easier to form the support structure for the movable bolt 33 relative to the receiving plate 32. Furthermore, the first receiving plate 32A is formed with the guide hole 321 that guides the head 33b of the movable bolt 33 in the second direction (the direction of arrow P2) while supporting it so that it cannot rotate. Therefore, when the interior part 2, 2B is fastened to the second receiving plate 32B via the movable bolt 33, the guide hole 321 prevents the movable bolt 33 from rotating, reducing the effort required for the screw fastening work.

In addition, according to this embodiment, the interior equipment 2 is a luggage rack 2B equipped with a luggage rack bracket 22B attached to an attachment plate 11G fixed to the inside of the car body of the side inner frame 12G of the side structure 1G. The fixing bolt 31 is fixed to the attachment plate 11G, and the mounting seat 21B of the luggage rack bracket 22B is fastened to the movable bolt 33. Therefore, the attachment positions of the first and second support plates 32A and 32B relative to the fixing bolt 31 fixed to the attachment plate 11G of the side structure 1G can be adjusted by moving the first and second support plates 32A and 32B in a first direction (direction of arrow P1) along the attachment surface 11 of the attachment plate 11G, and the attachment position of the luggage rack bracket 22B relative to the first and second support plates 32A and 32B can be adjusted by moving the movable bolt 33 in a second direction (direction of arrow P2) perpendicular to the first direction and along the attachment surface 11 of the attachment plate 11G. Additionally, by adjusting the thickness of the first and/or second support plates 32A and 32B, the attachment position of the luggage shelf bracket 22B relative to the mounting plate 11G can be adjusted in a third direction (perpendicular to the surface of the mounting surface 11 of the mounting plate 11G: the direction of arrow P3) that is perpendicular to the first and second directions. Therefore, the attachment position of the luggage shelf 2B relative to the side structure 1G can be easily adjusted in any direction, including front-to-rear, up-down, left-to-right, and the like, of the vehicle.

The second support plate 32B is formed to expose the bracket main body 22BH, which extends from the mounting seat 21B of the luggage rack bracket 22B toward the inside of the car body, and the lower end 42 of the side ceiling panel 4, which is formed to shield the mounting seat 21B of the luggage rack bracket 22B from the inspection window 1M formed in the side structure 1G, is fastened to the second support plate 32B in an adjustable mounting position. Therefore, by removing the lower end 42 of the side ceiling panel 4 from the second support plate 32B, the mounting position of the luggage rack 2B relative to the side structure 1G can be adjusted, and by attaching the lower end 42 of the side ceiling panel 4 to the second support plate 32B, the mounting seat 21B of the luggage rack bracket 22B is hidden, improving the appearance of the luggage rack 2B to passengers.

In addition, the lower end 42 of the side ceiling panel 4, which is designed to be able to cover the inspection window 1M formed in the side structure 1G, is fastened to the second support plate 32B in an adjustable mounting position, eliminating the need to provide a separate cover for the inspection window 1M; the side ceiling panel 4 can also serve as a cover for the inspection window 1M. Furthermore, because the side ceiling panel 4 is fastened to the second support plate 32B in an adjustable mounting position, when the mounting position of the second support plate 32B relative to the side structure 1G is adjusted, the mounting position of the side ceiling panel 4 relative to the second support plate 32B can be adjusted in accordance with the amount of adjustment.

Furthermore, according to this embodiment, the upper end 41 of the side ceiling panel 4 is provided with an elastic engagement portion 411 that clamps and engages a spring-like interlocking member 52, the attachment position of which is adjustable, attached to a hanging hardware 51 attached to the roof structure 5. This allows the lower end 42 of the side ceiling panel 4 to be removed from the second support plate 32B while the upper end 41 of the side ceiling panel 4 is attached to the hanging hardware 51 of the roof structure 5, while absorbing manufacturing errors, etc. Then, by elastically deforming the spring-like interlocking member 52 that engages with the elastic engagement portion 411, or by disengaging the elastic engagement portion 411 from the spring-like interlocking member 52, the side ceiling panel 4 can be separated from the inspection window 1M formed in the side structure 1G, allowing easy inspection of the equipment inside the inspection window 1M.

Furthermore, the manufacturing method for a railway vehicle according to this other embodiment includes a temporary fixing process S1 in which the interior parts 2, 2B are temporarily fixed to the receiving plate 32 (32A, 32B) using the movable bolts 33, and a temporary fixing process S2 in which the receiving plate 32 (32A, 32B) with the interior parts 2, 2B temporarily fixed thereto is temporarily fixed to the body structure 1, 1G using the fixing bolts 31. Therefore, by temporarily fixing the interior parts 2, 2B to the receiving plate 32 (32A, 32B) in the temporary fixing process S1, and then temporarily fixing the receiving plate 32 (32A, 32B) with the interior parts 2, 2B temporarily fixed thereto to the body structure 1, 1G in the temporary fixing process S2, the interior part 2 can be quickly attached to the body structure 1, 1G.

In addition, the system includes an adjustment process S3 in which the mounting positions of the temporarily fixed interior components 2, 2B are moved and adjusted to their correct positions relative to the body structure 1, 1G. This allows the mounting positions of the interior components 2, 2B to be moved and adjusted to their correct positions relative to the body structure 1, 1G while the interior components 2, 2B and the support plate 32 (32A, 32B) are temporarily fixed to the body structure 1, 1G. This eliminates the need for work such as drilling holes and threading female screws to fit the actual vehicle, and eliminates the need to support the interior components 2, 2B using a support jig or the like. This allows the mounting positions of the interior components 2, 2B to be easily and quickly moved and adjusted to their correct positions relative to the body structure 1, 1G.
