JP-A-2005-35533

However, the above-mentioned conventional technique has a problem that the overhanging portion easily interferes with the protruding portion when the ceiling panel is attached or detached.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a railway vehicle capable of making it difficult for the overhanging portion to interfere with the protruding portion when the ceiling panel is attached or detached.

In order to achieve this object, the railroad vehicle of the present invention has a plurality of ceiling panels lining up in the rail direction to form at least a part of the ceiling, and a plurality of protrusions protruding downward from between the plurality of ceiling panels. The ceiling panel is provided with a panel body whose end edge in the rail direction faces the projecting portion in the rail direction, and the ceiling panel projecting in the rail direction from only one side of the end edge of the panel body in the sleeper direction. It is provided with an overhanging portion located on one side of the protruding portion in the direction of the sleepers.

Further, the railroad vehicle of the present invention includes a plurality of ceiling panels lining up in the rail direction to form at least a part of the ceiling, and a plurality of projecting portions protruding downward from between the plurality of ceiling panels. The ceiling panel projects in the rail direction from only the panel body whose rail-direction edge faces the projecting portion in the rail direction and the end edge on one side of the panel body in the rail direction, and the projecting portion in the railroad tie direction. It is provided with a pair of overhangs located on both sides of the rail.

According to the railway vehicle according to claim 1, an overhanging portion projects in the rail direction from only one side of the edge of the panel body in the sleeper direction, and the overhanging portion is located on one side of the protruding portion in the sleeper direction. Therefore, when the ceiling panel is attached or detached, the ceiling panel can be moved by moving the overhanging portion away from or closer to the protruding portion while being careful not to interfere with the protruding portion on one side. As a result, it is possible to make it less likely that the overhanging portion interferes with the protruding portion when the ceiling panel is attached or detached, as compared with the case where the overhanging portion of the edge of the panel body projects from both sides in the sleeper direction.

According to the railway vehicle according to claim 2, the overhanging portion is a first overhanging portion that projects from one end edge of the panel body in the rail direction and a first overhanging portion that projects from the other end edge of the panel body in the rail direction. It has two overhangs. The first overhanging portion and the second overhanging portion face each other with the protruding portion in the sleeper direction. As a result, in addition to the effect of claim 1, the ceiling is surrounded by two ceiling panels on substantially the entire circumference of the protruding portion, as in the case where the protruding portions project from both sides of the edge of the panel body in the sleeper direction. It is possible to prevent the overhanging portion from interfering with the protruding portion when the panel is attached or detached.

According to the railway vehicle according to claim 3, the overhanging portion is a first overhanging portion that projects from one end edge of the panel body in the rail direction and a first overhanging portion that projects from the other end edge of the panel body in the rail direction. It has two overhangs. The first overhang and the second overhang provided on one ceiling panel are located on the same side in the sleeper direction. As a result, the ceiling panel can be attached and detached by sliding the ceiling panel toward the sleepers or downward without tilting the ceiling panel toward the rail. As a result, in addition to the effect of claim 1 or 2, the overhanging portion can be made less likely to interfere with the protruding portion when the ceiling panel is attached or detached.

According to the railway vehicle according to claim 4, the plurality of ceiling panels include a first panel in which the first overhanging portion and the second overhanging portion are located on the first side in the sleeper direction with respect to the protruding portion, and the protruding portion. It is provided with a second panel in which the first overhanging portion and the second overhanging portion are located on the second side opposite to the first side in the direction of the sleepers. The protrusion is inclined toward the first side as it goes downward from between the edges of the panel body. Therefore, when the first panel is slid downward, the overhanging portion of the first panel easily interferes with the protruding portion, while when the second panel is slid downward, the overhanging portion of the second panel is projected. Can be less likely to interfere with. That is, the second panel can be attached and detached more easily than the first panel.

Since there is at least one maximum portion between both ends of the ceiling in the rail direction that maximizes the distance between the protrusions adjacent to each other in the rail direction, the panel body of the ceiling panel arranged at the maximum portion becomes long. It becomes difficult to attach and detach the ceiling panel. As described above, since the second panel is easier to attach and detach than the first panel, the number of the second panels arranged in the maximum portion between both ends in the rail direction of the ceiling is the number of the first panels arranged in the maximum portion. By arranging the first panel and the second panel alternately in the rail direction as described above, in addition to the effect of claim 3, it is possible to easily attach / detach a plurality of ceiling panels.

According to the railway vehicle according to claim 5, the plurality of ceiling panels include a first panel in which the first overhanging portion and the second overhanging portion are located on the first side in the sleeper direction with respect to the protruding portion, and the protruding portion. It is provided with a second panel in which the first overhanging portion and the second overhanging portion are located on the second side opposite to the first side in the direction of the sleepers. The protrusion is inclined toward the first side as it goes downward from between the edges of the panel body. Therefore, when the first panel is slid downward, the overhanging portion of the first panel easily interferes with the protruding portion, while when the second panel is slid downward, the overhanging portion of the second panel is projected. Can be less likely to interfere with. That is, the second panel can be attached and detached more easily than the first panel.

The distance between the protrusions adjacent to each other in the rail direction is at least partially different between both ends in the rail direction of the ceiling, and the longer the panel body of the ceiling panel is according to the distance, the more difficult it becomes to attach and detach the ceiling panel. Between both ends of the ceiling in the rail direction, the total distance from one end in the rail direction to the odd number is compared with the total distance in the even number, and the smaller total is the first panel that is relatively difficult to attach and detach. By arranging the second panel, which is relatively easy to attach / detach to the one having the larger total, in addition to the effect of claim 3 or 4, it is possible to easily attach / detach a plurality of ceiling panels.

According to the railway vehicle according to claim 6, a pair of overhangs project in the rail direction from only one end edge of the panel body in the rail direction, and the pair of overhangs project on both sides of the projecting portion in the sleeper direction. To position. Therefore, in order to remove the ceiling panel, the edge with the pair of overhangs is used as a fulcrum, the edge without the pair of overhangs is moved downward, the ceiling panel is tilted, and then the pair of overhangs is removed. Slide or rotate the ceiling panel so that some edges are separated from the protrusions. To install the ceiling panel, reverse the process. As a result, the pair of overhanging portions can be less likely to interfere with the protruding portions when the ceiling panel is attached or detached, as compared with the case where the pair of overhanging portions project from both end edges in the rail direction of the panel body.

It is sectional drawing of the railroad vehicle in the VII-VII line of FIG.

Hereinafter, preferred embodiments will be described with reference to the accompanying drawings. First, the railway vehicle 10 according to the first embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a cross-sectional view of the railroad vehicle 10 perpendicular to the rail direction. FIG. 2 is a cross-sectional view of the railroad vehicle 10 on the line II-II of FIG. 1, and one outer panel 30 is enlarged and shown. In FIG. 1, the left side of the railroad vehicle 10 formed substantially symmetrically is omitted, the lower part of the railroad car 10 is omitted, and each member installed between the roof structure 12 and the ceiling plate 14 is illustrated. It is omitted. Further, for convenience of explanation, the arrow U direction in each drawing is the upward direction of the railway vehicle 10, similarly, the arrow D direction is the downward direction, the arrow L direction is the left direction, the arrow R direction is the right direction, and the arrow F direction is the front direction. The direction and the direction of arrow B are the backward directions.

As shown in FIG. 1, the railroad vehicle 10 is installed on the underframe (not shown), the side structures 11 erected on both sides of the underframe in the sleeper direction (left-right direction), and the upper part of the side structures 11. The roof structure 12 and the wife structure 13 erected on both sides of the underframe in the rail direction (front-rear direction) are provided. The roof structure 12 suspends and supports the ceiling plate 14 of the guest room by a support member (not shown). Since the railway vehicle 10 is formed substantially symmetrically to the left and right, the right side of the railway vehicle 10 will be described and the description on the left side will be omitted unless otherwise specified.

The ceiling plate 14 is a portion that forms most of the ceiling of the guest room. Grooves 14a recessed upward (on the roof structure 12 side) are continuously formed in the ceiling plate 14 in the rail direction. Grooves 14a are provided on both the left and right sides of the ceiling plate 14, respectively.

A plurality of suspension rod receivers (protruding portions) 15 are attached to the groove bottom of the groove portion 14a at intervals in the rail direction. Further, a plurality of lighting fixtures 22 are arranged between the plurality of hanging handle bar receivers 15, and the lighting fixtures 22 are attached to the groove bottom of the groove portion 14a via the support member 20.

The hanger bar holder 15 is a plate-shaped metal member whose front and rear surfaces are substantially perpendicular to the rail direction, and its width decreases from the upper end to the lower end. In the hanging bar holder 15, a flange 15a projecting from the upper end in the rail direction is attached to the groove bottom of the groove portion 14a by a bolt 15b. The hanger bar receiver 15 curves (inclines) toward the vehicle center side (first side) in the sleeper direction toward the lower end of the hanger bar receiver 15 from the flange 15a.

At the lower ends of the plurality of hanging hand rod receivers 15 arranged in the rail direction, a hanging hand rod 16 long in the rail direction is supported. A plurality of suspension rods 17 long in the sleeper direction are bridged to the suspension rods 16 symmetrically arranged at intervals in the rail direction. Hangers 18 and 19 gripped by standing passengers are hung from the hanger rods 16 and 17, respectively.

The lighting fixture 22 includes a lighting main body 23 that illuminates the inside of the guest room, and a semi-transparent semi-cylindrical cover 24 that covers the lighting main body 23. The lighting body 23 is attached to the support member 20 by bolts 25. Then, by attaching the support member 20 to the groove bottom of the groove portion 14a by the bolt 21, the luminaire 22 is fixed to the ceiling plate 14 in a state of being slightly tilted toward the center of the vehicle in the direction of the sleepers. The hanging bar 16 and the lighting device 22 are separated from each other in the direction of the sleepers by bending the hanging bar receiver 15 so that the hanging bar 16 is located directly under the lighting fixture 22 and the guest room is not darkened.

As shown in FIGS. 1 and 2, the outer panel (second panel) 30 and the inner panel (first panel) as a plurality of ceiling panels forming a part of the ceiling are sandwiched between the plurality of hanging hand rod receivers 15. ) 35 are alternately arranged in the rail direction. The outer panel 30 and the inner panel 35 are overlapped on the ceiling plate 14 side of the lighting main body 23, and are attached to the support member 20 together with the lighting main body 23 by bolts 25.

The groove 14a is covered by the outer panel 30 and the inner panel 35 fixed to the ceiling plate 14 via the support member 20, and the flange 15a and bolts 15b of the hanging bar holder 15, the support member 20, and the bolt 21 are received from passengers in the cabin. Since it can be difficult to see, you can improve the appearance from inside the guest room. Further, since the bolt 25 for fixing the outer panel 30 and the inner panel 35 to the ceiling plate 14 is covered with the cover 24, the appearance from the inside of the guest room can be improved.

The outer panel 30 has a panel main body 31, an outer front overhanging portion (first overhanging portion) 33 protruding forward from the front end edge 31a of the panel main body 31, and a rear end edge 31b of the panel main body 31. It is provided with an outer rear overhanging portion (second overhanging portion) 34 that projects rearward from the surface. The inner panel 35 has a panel main body 36, an inner front overhanging portion (first overhanging portion) 38 protruding forward from the front end edge 36a of the panel main body 36, and a rear end edge 36b of the panel main body 36. It is provided with an inner rear overhanging portion (second overhanging portion) 39, which overhangs rearward from the above.

The hanging hand rod holder 15 projects downward from between the edge 31a of the panel body 31 and the edge 36b of the panel body 36, and between the edge 31b of the panel body 31 and the edge 36a of the panel body 36, respectively, and ends. The edges 31a, 31b, 36a, 36b face the hanging bar holder 15 in the rail direction. The edge edges 31a, 31b, 36a, 36b are formed linearly in the sleeper direction and project from the hanging bar holder 15 to both sides in the sleeper direction. The gaps in the rail direction between the end edges 31a, 31b, 36a, 36b and the hanger bar holder 15 are substantially the same over the entire length in the sleeper direction, and are based on the thickness (rail direction dimension) of the hanger bar holder 15. Is also small. As a result, the groove portion 14a side can be made difficult to see from the passenger compartment through the gap between the end edges 31a, 31b, 36a, 36b and the hanging bar holder 15.

The outer front overhang 33 and the outer back overhang 34 are integrally molded with the panel body 31. The outer front overhanging portion 33 projects from only the outside of the vehicle in the sleeper direction (right side, second side) of the end edge 31a, and is located on the outside of the vehicle in the sleeper direction with respect to the hanging bar holder 15. The outer rear overhanging portion 34 projects from only the outside of the vehicle in the direction of the sleepers among the edge 31b, and is located on the outside of the vehicle in the direction of the sleepers with respect to the hanging bar holder 15.

The inner front overhang 38 and the inner back overhang 39 are integrally molded with the panel body 36. The inner front overhanging portion 38 projects from only the vehicle center side (left side, first side) in the sleeper direction of the edge 36a, and is located on the vehicle center side in the sleeper direction with respect to the hanging bar holder 15. The inner rear overhanging portion 39 projects from only the vehicle center side in the sleeper direction of the edge 36b, and is located on the vehicle center side in the sleeper direction with respect to the hanging bar holder 15.

Since the outer panel 30 and the inner panel 35 are made of metal and there is a hanging bar holder 15 in the immediate vicinity, the end edges 31a, 31b, 36a, 36b and each of them are used when the outer panel 30 and the inner panel 35 are attached and detached. If the corners of the overhanging portions 33, 34, 38, 39 hit the hanging bar holder 15, the hanging bar holder 15 may be damaged. Therefore, it is desired to attach / detach the outer panel 30 and the inner panel 35 so that the outer panel 30 and the inner panel 35 do not hit the hanging bar holder 15.

Since the plurality of overhanging portions 33, 34, 38, 39 project from only one side of the end edges 31a, 31b, 36a, 36b in the direction of the sleepers, when the outer panel 30 or the inner panel 35 is attached or detached, one side thereof While taking care that the overhanging portions 33, 34, 38, 39 do not interfere with the hanging hand rod receiver 15, move the overhanging portions 33, 34, 38, 39 away from or closer to the hanging hand rod receiver 15 to the outside. The panel 30 and the inner panel 35 can be moved. As a result, as compared with the conventional ceiling panel in which the overhanging portions project from both sides in the sleeper direction at both end edges in the rail direction, the overhanging portions 33, 34, 38, 39 are formed when the outer panel 30 and the inner panel 35 are attached / detached. It can be made less likely to interfere with the hanging hand rod receiver 15.

In particular, the outer front overhang 33 and the outer rear overhang 34 provided on one outer panel 30 are both located on the outside of the vehicle in the direction of the sleepers, and the inner front overhangs 35 provided on each inner panel 35. Both the protruding portion 38 and the inner rear protruding portion 39 are located on the vehicle center side in the direction of the sleepers. Therefore, the outer panel 30 and the inner panel 35 can be attached and detached by sliding the outer panel 30 and the inner panel 35 toward the sleepers and downward without tilting the outer panel 30 and the inner panel 35 toward the rail. As a result, when the outer panel 30 and the inner panel 35 are attached / detached, the overhanging portions 33, 34, 38, 39 can be made less likely to interfere with the hanging hand rod receiver 15.

The hanging bar holder 15 is curved (inclined) toward the center of the vehicle in the direction of the sleepers as it goes downward from between the end edges 31a, 31b, 36a, and 36b. Therefore, when the inner panel 35 is slid downward, the inner front overhanging portion 38 and the inner back overhanging portion 39 of the inner panel 35 are likely to interfere with the hanging hand rod receiver 15. Therefore, when attaching / detaching the inner panel 35, the inner panel 35 is slid toward the sleepers, the inner panel 35 is sufficiently separated from the hanging bar holder 15, and then the inner panel 35 is tilted toward the rail or slid downward. Is preferable.

On the other hand, since the outer front overhanging portion 33 and the outer back overhanging portion 34 of the outer panel 30 are located on the side opposite to the bending direction of the hanging hand rod receiver 15, when the outer panel 30 is slid downward, the outer panel 30 is outside. The front overhanging portion 33 and the outer rear overhanging portion 34 can be prevented from interfering with the hanging hand rod receiver 15. That is, the outer panel 30 can be attached and detached more easily than the inner panel 35.

In a state where the outer panel 30 and the inner panel 35 are adjacent to each other in the rail direction, the outer front overhanging portion 33 and the inner back overhanging portion 39 face each other with the hanging bar holder 15 in the sleeper direction. Similarly, the outer rear overhanging portion 34 and the inner front overhanging portion 38 face each other with the hanging hand rod receiver 15 in the direction of the sleepers. As a result, as in the case of the conventional ceiling panel in which the overhanging portions project from both sides in the sleeper direction at both end edges in the rail direction, the outer panel 30 and the inner panel 35 surround substantially the entire circumference of the hanging bar holder 15. When the outer panel 30 and the inner panel 35 are attached / detached, the overhanging portions 33, 34, 38, 39 can be prevented from interfering with the hanging hand rod receiver 15.

The gap between the overhanging portions 33, 34, 38, 39 and the hanging bar holder 15 in the sleeper direction is smaller than the thickness of the hanging bar holder 15. As a result, the groove portion 14a side can be made difficult to see from the passenger compartment through the gap between the overhanging portions 33, 34, 38, 39 and the hanging bar holder 15. Further, the gap between the overhanging portions 33, 34, 38, 39 and the end edges 31a, 31b, 36a, 36b in the rail direction is smaller than the thickness of the hanging bar holder 15. As a result, the groove portion 14a side can be made difficult to see from the guest room through the gap between the overhanging portions 33, 34, 38, 39 and the edge portions 31a, 31b, 36a, 36b.

The gap between the outer front overhang portion 33 and the end edge 36b and the gap between the hanging bar holder 15 and the end edge 36b have substantially the same rail direction dimensions over the entire length in the sleeper direction. As a result, the tip edge of the outer front overhanging portion 33 in the rail direction is located on the same plane as the surface of the hanging hand rod receiver 15 facing the end edge 36b, so that the appearance around the end edge 36b can be improved. Similarly, since the tip edges of the overhanging portions 34, 38, 39 are located on the same plane as the surface of the hanging hand rod receiver 15 facing the end edges 31a, 31b, 36a, the end edges 31a, 31b, 36a You can improve the appearance of the surrounding area.

Next, the overall configuration of the ceiling between both ends in the rail direction of the guest room will be described with reference to FIG. FIG. 3 is a schematic view of the ceiling of a railroad vehicle in which a plurality of outer panels 30 and inner panels 35 are arranged side by side. In the description of FIG. 3, a plurality of outer panels 30 and inner panels 35 will be described as outer panels 30a, 30b, 30c and inner panels 35a, 35b, 35c in order from the rear end of the ceiling.

As shown in FIG. 3, there are wife structures 13 at both ends of one railroad vehicle 10 in the rail direction, and the wife structures 13 are both ends of the ceiling of the passenger compartment in the rail direction. Hereinafter, unless otherwise specified, the space between both ends of the ceiling in the rail direction (one railroad vehicle 10) will be described.

Five hanging handle holders 15 are arranged in a row on each of the left and right sides in the rail direction. The intervals between the hanging bar receivers 15 adjacent to each other in the rail direction include the longest interval L1, the interval L2 shorter than the interval L1, and the interval L3 shorter than the interval L2. The intervals between the hanging bar receivers 15 are, in order from the rear end in the rail direction of the ceiling, the interval L1, the interval L3, the interval L3, and the interval L2.

At a position separated from the front end of the ceiling in the rail direction by an interval L4 in the rail direction, there is a hanging bar holder 15 closest to the front end. Further, the distance L5 in the rail direction from the rear end in the rail direction of the ceiling to the hanger bar receiver 15 closest to the rear end is shorter than the distance L4.

The outer panels 30 and the inner panels 35 having panel bodies 31 and 36 (see FIG. 2) having lengths corresponding to these intervals L1, L2, L3, L4, and L5 are alternately arranged side by side in the rail direction. Specifically, in order from the rear end in the rail direction of the ceiling, the inner panel 35a is located at the interval L5, the outer panel 30a is located at the interval L1, the inner panel 35b is located at the interval L3, and the outer panel is located at the interval L3. The inner panel 35c is arranged at the position of the interval L2, and the outer panel 30c is arranged at the position of the interval L4.

The inner rear overhang 39 does not project from the edge 36b (see FIG. 2) of the inner panel 35a along the rear end in the rail direction of the ceiling. Further, the outer front projecting portion 33 does not project from the edge 31a (see FIG. 2) of the outer panel 30c along the front end in the rail direction of the ceiling. As a result, the inner panel 35a and the outer side are compared with the outer panels 30a and 30b and the inner panels 35b and 35c in which the overhanging portions 33, 34, 38 and 39 project from both end edges 31a, 31b, 36a and 36b, respectively. The panel 30c can be easily attached and detached.

The outer panels 30a, 30b, 30c and the inner panels 35a, 35b, 35c become longer as the distances L1, L2, L3, L4, L5 of the portions where they are arranged become longer. The longer the outer panels 30a, 30b, 30c and the inner panels 35a, 35b, 35c are, the more difficult it is to handle the outer panels 30a, 30b, 30c and the inner panels 35a, 35b, 35c at the time of attachment / detachment. In particular, the longer the outer panels 30a, 30b and the inner panels 35b, 35c having the two overhangs 33, 34, 38, 39, the longer the attachment / detachment while checking both the overhangs 33, 34, 38, 39. Work becomes difficult.

As described above, the outer panels 30a, 30b, 30c are easier to attach and detach than the inner panels 35a, 35b, 35c depending on the positional relationship of the overhanging portions 33, 34, 38, 39 with respect to the bending direction of the hanging bar holder 15. Therefore, by arranging the outer panel 30a in the portion (maximum portion) of the interval L1 where the interval between the hanging hand rod receivers 15 adjacent to each other in the rail direction is maximum, even if the panel body 31 at the maximum interval L1 becomes long. The work of attaching and detaching the outer panel 30a can be easily performed.

On the other hand, since the inner panels 35b and 35c, which are relatively difficult to attach and detach, can be arranged at the portions of the intervals L2 and L3 shorter than the interval L1, the inner panels 35b and 35c can be easily attached and detached. As a result, it is possible to easily attach / detach the plurality of outer panels 30a and 30b and the inner panels 35b and 35c arranged between the hanging hand rod receivers 15 adjacent to each other in the rail direction.

Further, with respect to the distances L1, L2, and L3 between the suspension rod receivers 15 adjacent to each other in the rail direction, the sum of the distances L1 and the distance L3 at the odd-numbered positions from the rear end in the rail direction and the distances at the even-numbered positions from the rear end in the rail direction. Comparing the sum of L3 and the interval L2, the odd-numbered sum is larger. The total length of the plurality of outer panels 30 or inner panels 35 arranged on the larger side becomes larger, and it becomes difficult to attach / detach the plurality of outer panels 30 or inner panels 35 having a larger total length. Therefore, by arranging the inner panels 35b and 35c that are relatively difficult to attach and detach to the smaller total (even number) and the outer panels 30a and 30b that are relatively easy to attach and detach to the larger total (odd number). The work of attaching and detaching the plurality of inner panels 35b and 35c and the outer panels 30a and 30b can be easily performed.

Further, the distance L4 from the front end of the ceiling in the rail direction to the hanging hand rod receiver 15 is larger than the distance L5 from the rear end of the ceiling in the rail direction to the hanging hand rod receiver 15. The outer panel 30c, which is relatively easy to attach / detach, is arranged at the interval L4, and the inner panel 35a, which is relatively difficult to attach / detach, is arranged at the interval L5. As a result, the outer panel 30c and the inner panel 35a, which are arranged at both ends in the rail direction of the ceiling, can be easily attached and detached.

Next, the second embodiment will be described with reference to FIG. In the first embodiment, the case where the outer panel 30 and the inner panel 35 are alternately arranged has been described. On the other hand, in the second embodiment, a case where similar ceiling panels 40 are arranged in the rail direction will be described. The same parts as those in the first embodiment are designated by the same reference numerals, and the following description will be omitted.

FIG. 4 is a cross-sectional view of a railroad vehicle according to the second embodiment, and one ceiling panel 40 is enlarged and shown. As shown in FIG. 4, the ceiling panel 40 of the railway vehicle in the second embodiment forms a part of the ceiling. The ceiling panel 40 is formed from the panel main body 41, the inner overhanging portion (first overhanging portion) 43 projecting forward from the front edge 41a of the panel main body 41, and the rear edge 41b of the panel main body 41. It is provided with an outer overhanging portion (second overhanging portion) 44 that overhangs rearward.

The hanging hand rod receiver 15 projects downward from between the edge 41a and 41b of the panel main body 41 adjacent to each other in the rail direction, and the end edges 41a and 41b face the hanging hand rod holder 15 in the rail direction. The edge edges 41a and 41b are formed linearly in the direction of the sleepers, and project from the hanging bar holder 15 to both sides in the direction of the sleepers.

The inner overhanging portion 43 and the outer overhanging portion 44 are integrally molded with the panel main body 41. The lining portion 43 projects from only the vehicle center side (left side) in the sleeper direction of the end edge 41a, and is located on the vehicle center side of the hanger bar receiver 15. The outer overhanging portion 44 projects from only the outer side (right side) of the vehicle in the direction of the sleepers of the end edge 41b, and is located on the outer side of the vehicle of the hanging bar receiver 15. As described above, since the inner overhanging portion 43 and the outer overhanging portion 44 project from only one side of the end edges 41a and 41b in the sleeper direction, respectively, as in the first embodiment, when the ceiling panel 40 is attached / detached. The inner overhanging portion 43 and the outer overhanging portion 44 can be made less likely to interfere with the hanging hand rod receiver 15.

The inner overhanging portion 43 and the outer overhanging portion 44, which project from the end edges 41a and 41b facing each other in the rail direction, face each other with the hanging hand rod receiver 15 in the sleeper direction. As a result, substantially the entire circumference of the hanging bar receiver 15 can be surrounded by the two ceiling panels 40.

Since the inner overhanging portion 43 is provided on the vehicle center side of one ceiling panel 40 and the outer overhanging portion 44 is provided on the outer side of the vehicle, the length of the panel main body 41 is different, but the ceiling has the same shape. The panels 40 can be arranged in the rail direction. As a result, the number of parts of the ceiling panel 40 can be omitted, and the mounting position of the ceiling panel 40 can be prevented from being mistaken.

Since the hanging bar holder 15 is curved (tilted) toward the center of the vehicle in the direction of the sleepers as it goes downward from between the end edges 41a and 41b, when the ceiling panel 40 is removed, it is fixed to the ceiling plate 14. Even if the outer overhanging portion 44 is moved downward, the outer overhanging portion 44 can be less likely to interfere with the hanging hand rod receiver 15. Therefore, when removing the ceiling panel 40, first, the ceiling panel 40 is tilted toward the rail by moving the outer overhanging portion 44 downward with the inner overhanging portion 43 side as a fulcrum. Then, with the ceiling panel 40 tilted to some extent, the ceiling panel 40 is slid or rotated in the rail direction so that the lining portion 43 does not interfere with the hanging bar holder 15. When installing the ceiling panel 40, the reverse operation is performed. In this way, the ceiling panel 40 can be easily attached and detached even if the inner overhanging portion 43 and the outer overhanging portion 44 are located on different sides of the ceiling panel 40 in the sleeper direction, respectively.

Next, the third embodiment will be described with reference to FIG. In the first and second embodiments, the overhanging portions 33, 34, 38, 39, 43 from only one side in the sleeper direction among the edge edges 31a, 31b, 36a, 36b, 41a, 41b of the panel bodies 31, 36, 41. , 44 overhangs have been described. On the other hand, in the third embodiment, the case where the inner overhanging portion 53 and the outer overhanging portion 54 project from only the end edge 51b on one side in the rail direction of the panel main body 51 will be described. The same parts as those in the first embodiment are designated by the same reference numerals, and the following description will be omitted.

FIG. 5 is a cross-sectional view of a railroad vehicle according to a third embodiment, and one ceiling panel 50 is enlarged and shown. As shown in FIG. 5, the ceiling panel 50 of the railway vehicle in the third embodiment forms a part of the ceiling. The ceiling panel 50 includes a panel main body 51, and an inner overhang 53 and an outer overhang 54 (a pair of overhangs) that project rearward from the rear edge 51b of the panel body 51, respectively. .. On the other hand, the inner overhanging portion 53 and the outer overhanging portion 54 do not project from the front edge 51a of the panel main body 51.

The hanging hand rod receiver 15 projects downward from between the end edges 51a and 51b of the panel main bodies 51 adjacent to each other in the rail direction, and the end edges 51a and 51b face the hanging hand rod holder 15 in the rail direction. The edge edges 51a and 51b are formed linearly in the direction of the sleepers, and project from the hanging bar holder 15 to both sides in the direction of the sleepers. The distance between the hanging hand rod receivers 15 adjacent to each other in the rail direction and the length between the end edges 51a and 51b of one panel main body 51 arranged between them are substantially the same. More specifically, the length of the panel body 51 is slightly shorter than the distance between the hanging bar receivers 15.

The inner overhanging portion 53 and the outer overhanging portion 54 are integrally molded with the panel main body 51. The lining portion 53 projects from the vehicle center side (left side) in the sleeper direction of the end edge 51b, and is located on the vehicle center side of the hanger bar receiver 15. The outer overhanging portion 54 projects from the outer side (right side) of the vehicle in the direction of the sleepers of the end edge 51b, and is located on the outer side of the vehicle of the hanging bar receiver 15. Abbreviation for the hanging hand rod holder 15 by the inner overhanging portion 53 and the outer overhanging portion 54 located on both sides of the hanging hand rod holder 15 in the sleeper direction and the edge edges 51a and 51b of the panel body 51 adjacent to each other in the rail direction. The whole circumference is surrounded.

To remove one ceiling panel 50 from the ceiling plate 14 (see FIG. 1), first remove the bolt 25 to release the fixing of the ceiling panel 50 to the ceiling plate 14. Next, the ceiling panel 50 is tilted by moving the edge 51a downward while using the edge 51b where the inner overhang 53 and the outer overhang 54 are located as a fulcrum. Since the edge 51a does not have an inner overhang 53 and an outer overhang 54, the vicinity of the edge 51a does not hit the hanging bar holder 15 when the edge 51a is moved downward.

The hanging bar holder 15 is curved toward the center of the vehicle in the direction of the sleepers toward the lower end, and the hanging bar 16 connecting the lower ends of the hanging bar holder 15 is not below the ceiling panel 50 (see FIG. 1). Therefore, the end edge 51a can be moved below the lower end of the hanging bar holder 15 to greatly tilt the ceiling panel 50. In this state, since there is no hanging bar holder 15 around the edge 51a, the edge 51a does not hit the hanging bar holder 15 even if the ceiling panel 50 is slid or rotated.

Therefore, after the ceiling panel 50 is greatly tilted, the ceiling panel 50 is slid or rotated so that the end edge 51b is separated from the hanging bar holder 15, and the hanging hand is placed between the inner overhanging portion 53 and the outer overhanging portion 54. By pulling out the rod holder 15, the ceiling panel 50 can be taken out from between the pair of hanging hand rod holders 15. To attach the ceiling panel 50, the reverse process is performed. As described above, in the present embodiment, as compared with the case where the inner overhanging portion 53 and the outer overhanging portion 54 project from both the end edges 51a and 51b, the inner overhanging portion 53 and the outer overhanging portion 53 and the outer overhanging portion when the ceiling panel 50 is attached / detached The protrusion 54 can be made less likely to interfere with the hanging bar receiver 15.

Even when the hanging bar 16 connecting the lower ends of the hanging bar receiver 15 is below the ceiling panel 50, the more the ceiling panel 50 is tilted so that the end edge 51a approaches the hanging bar 16, the more in the rail direction. The amount of slide of the ceiling panel 50 in the rail direction between the adjacent hanging bar receivers 15 can be increased. After tilting the ceiling panel 50, the ceiling panel 50 is slid in the rail direction so that the end edge 51b is separated from the hand bar holder 15, and the hanging hand bar holder 15 is inserted between the inner overhanging portion 53 and the outer overhanging portion 54. If it can be taken out, the ceiling panel 50 can be slid in the direction of the sleepers and taken out from between the hanging bar holders 15.

Further, since the inner overhanging portion 53 and the outer overhanging portion 54 are provided on the end edge 51b on one side of the ceiling panel 50 in the rail direction, the length of the panel main body 51 is the same as in the second embodiment. Although different, ceiling panels 50 having the same shape can be arranged in the rail direction. As a result, the number of parts of the ceiling panel 50 can be omitted, and the mounting position of the ceiling panel 50 can be prevented from being mistaken.

Next, the fourth embodiment will be described with reference to FIGS. 6 and 7. In the first embodiment, the outer panel 30 and the inner panel 35 forming the ceiling around the luminaire 22 have been described. On the other hand, in the fourth embodiment, the outer panel 70 and the inner panel 75, which form the ceiling around the lighting fixture 22 and are provided with the air outlet 72 for blowing the conditioned air to the guest room side, will be described. The same parts as those in the first embodiment are designated by the same reference numerals, and the following description will be omitted. Since the hanger bar receiver according to the fourth embodiment has the same configuration as the hanger bar receiver 15 according to the first embodiment except that it extends linearly downward from the flange 15a, the hanger bar receiver according to the fourth embodiment is suspended. The hand stick holder is designated by the same reference numerals as those in the first embodiment.

FIG. 6 is a cross-sectional view perpendicular to the rail direction of the railway vehicle 60 according to the fourth embodiment. FIG. 7 is a cross-sectional view of a railroad vehicle 60 on the VII-VII line of FIG. 6, in which one outer panel 70 is enlarged and shown.

Further, in FIG. 6, except for the duct 61 and the fixtures 63 and 64 for fixing the duct 61 to the roof structure 12, the illustration of each member installed between the roof structure 12 and the ceiling plate 14 is omitted.

As shown in FIG. 6, the railroad vehicle 60 further includes a duct 61 arranged between the roof structure 12 and the ceiling plate 14 with respect to the railroad car 1 of the first embodiment. The duct 61 is an air passage for supplying the air-conditioning air sent from the air-conditioning device (not shown) to each part of the guest room extending in the rail direction. The duct 61 is formed in a square tube shape extending in the rail direction, and is arranged outside the vehicle with respect to the lighting fixture 22.

Both ends of the duct 61 in the sleeper direction are suspended and supported by the roof structure 12 via fixtures 63 and 64. In FIG. 6, fixtures 63 and 64 are schematically illustrated. On the lower surface of the duct 61, an opening 62 for sending the conditioned air downward (to the guest room side) is provided.

The ceiling plate 14 is formed with a through hole 66 through which the air-conditioning air sent downward from the opening 62 of the duct 61 passes. The through hole 66 is arranged directly below the opening 62. The through hole 66 and the opening 62 have the same dimensions in the rail direction and in the sleeper direction.

A cushioning material 65 is sandwiched between the upper surface of the ceiling plate 14 and the lower surface of the duct 61 over the entire circumference of the opening 62 and the through hole 66. The cushioning material 65 is formed of a material having a predetermined flexibility (an elastic material such as sponge, rubber, or a thermoplastic elastomer). The cushioning material 65 relaxes the contact between the ceiling plate 14 and the duct 61 due to vibration during traveling. Further, the air conditioning air emitted from the opening 62 can be guided to the through hole 66 by the cushioning material 65, and the air conditioning air can be prevented from escaping from between the ceiling plate 14 and the duct 61.

As shown in FIGS. 6 and 7, the outer panels 70 and the inner panels 75 as the plurality of ceiling panels forming a part of the ceiling are alternately arranged in the rail direction between the plurality of hanging bar receivers 15. There is. The outer panel 70 and the inner panel 75 are overlapped on the ceiling plate 14 side of the lighting main body 23, and are attached to the support member 20 together with the lighting main body 23 by bolts 25.

By removing the outer panel 70 and the inner panel 75 from the ceiling plate 14, maintenance (inspection and cleaning) inside the duct 61 is performed through the through hole 66 and the opening 62. That is, the outer panel 70 and the inner panel 75 also serve as an inspection lid for the duct 61.

The outer panel 70 has a panel main body 71, an outer front overhang portion (first overhanging portion) 73 projecting forward from the front end edge 71a of the panel main body 71, and a rear end edge 71b of the panel main body 71. It is provided with an outer rear overhanging portion (second overhanging portion) 74 that overhangs rearward from the surface. The outer front overhang 73 and the outer back overhang 74 of the outer panel 70 are the same as the outer front overhang 33 and the outer back overhang 34 in the first embodiment, except that the dimensions in the sleeper direction are large. It is configured.

The inner panel 75 includes a panel main body 76, an inner front overhanging portion 38 projecting forward from the front end edge 76a of the panel main body 76, and an inner rear projecting rearward from the rear end edge 76b of the panel main body 76. It is provided with an overhanging portion 39. The edge 71a of the panel body 71 and the edge 76b of the panel body 76 face each other in the rail direction with the hanging strap holder 15 in between. The edge 71b of the panel body 71 and the edge 76a of the panel body 76 face each other in the rail direction with the hanging strap holder 15 in between.

The overhanging portions 38, 39, 73, 74 project from only one side of the edge 71a, 71b, 76a, 76b in the sleeper direction, respectively. Therefore, as in the first embodiment, in the present embodiment as well, when the outer panel 70 and the inner panel 75 are attached and detached, the overhanging portions 38, 39, 73, and 74 can be less likely to interfere with the hanging hand rod receiver 15.

A plurality of outlets 72 are formed through the panel bodies 71 and 76 that cover the through holes 66 (directly below the through holes 66) in the plate thickness direction. The air-conditioning air sent downward from the opening 62 of the duct 61 passes through the through hole 66 of the ceiling plate 14 and is blown out from the air outlet 72 to the passenger compartment side.

The plurality of outlets 72 are arranged in two rows in the sleeper direction and five in the rail direction with respect to one panel body 71, 76. The number of outlets 72 in the sleeper direction and the rail direction may be changed as appropriate. Since the opening size of the air outlet 72 is sufficiently smaller than the opening size of the through hole 66, it is possible to make it difficult to see the inside of the duct 61 through the air outlet 72 from the passenger compartment side.

A cushioning material 68 is sandwiched between the upper surfaces of the panel bodies 71 and 76 and the lower surface of the ceiling plate 14 over the entire circumference of the through hole 66. The cushioning material 68, like the cushioning material 65, is made of a material having a predetermined flexibility. The cushioning material 68 relaxes the contact between the ceiling plate 14 and the panel bodies 71 and 76 due to vibration during traveling. Further, the conditioned air emitted from the through hole 66 can be guided to the outlet 72 by the cushioning material 68, and the conditioned air can be prevented from escaping between the ceiling plate 14 and the panel bodies 71 and 76.
