DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interior structure of a railway vehicle, and more particularly to an interior ceiling structure and a profile used therefor.

[0002]

2. Description of the Related Art On the ceiling of a conventional general railway vehicle, a ventilation passage with a louver for a fan is provided at a central portion in the width direction of the vehicle, and a louver for an air conditioner is provided to the left and right through an air conditioning duct. A vented airway is provided. A nonflammable decorative plate or the like in which a flat plate made of aluminum is coated with a melamine resin is provided in a portion other than the ventilation path with the louver.

[0003]

However, the conventional ceiling structure has a poor rigidity because a flat member is used. Therefore, when the vehicle is used long in the longitudinal direction (rail direction), it is necessary to appropriately reinforce the vehicle in the width direction (sleeper direction). In addition, the inspection lid for a side destination indicator or the like does not have rigidity, so that it is necessary to appropriately add reinforcement. For these reasons, the number of steps and the number of parts are increased. In addition, since the ceiling material is flat and has no rigidity, the pitch of the mounting screws cannot be widened, and in this respect, the number of man-hours cannot be avoided.

[0004] In the manufacture of railway vehicles, variations in the dimensions peculiar to the vehicle structure are caused by the front and rear end walls of the vehicle,
It is necessary to absorb the joint width of the joints between the ceiling materials, but when the ceiling material is a flat plate as in the related art, there is a disadvantage that the gaps between the joints are easily noticeable. Therefore, it was difficult to absorb the dimensional variation peculiar to the vehicle structure.

Further, in the conventional structure, simply fixing the flat ceiling material to the vehicle body with the screw causes the head of the screw to be conspicuous, which is undesirable in terms of design.

For this reason, in the conventional method, a decorative plate is cut at the site in accordance with the dimensions of the structure, and then an aluminum frame called a pressing surface is attached to the periphery of the cut surface and installed on the structure. There was much upward work, and work efficiency was poor. In addition, the necessity of work on site has a disadvantage that it is necessary to adjust the context of other work.

The present invention has been made in view of the above circumstances, and a main object of the present invention is to reduce the number of parts and man-hours, and to efficiently construct a railcar ceiling with a simple structure. It is another object of the present invention to provide a ceiling structure which is easy to absorb variations in dimensions peculiar to a vehicle structure, and is excellent in functional and decorative design effects.

[0008]

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION The ceiling structure for a railway vehicle according to the present invention and the profile used therefor will be described in further detail below.

FIG. 1 is a longitudinal sectional view showing an example of a railway vehicle 1 to which an embodiment of a ceiling structure according to the present invention is applied. FIG. 2 is an enlarged view of a part of the ceiling of the railway vehicle 1.

As shown in these figures, the ceiling structure of the present invention is provided from the upper portion of the vehicle structures 11 and 12, ie, from the upper portion of the side structure 12 to the roof structure 11.

For the ceiling structure of the present invention, a profile, that is, a long material having a required same cross-sectional shape is cut out to an appropriate size and used. As the profile, an extruded aluminum profile (aluminum profile) is preferably used, but an extruded profile of a resin such as polycarbonate or a drawn profile such as FRP can also be used. In this embodiment, as will be described later, the ceiling lamp 13 and the air conditioner outlet 14a are formed of polycarbonate (the ceiling light cover plate 5 and the third ceiling plate 4), while other shapes are formed. Is made of extruded aluminum.

Each of the shaped members 2 to 7 functioning as a ceiling member constituting the ceiling is provided at least at a lower portion of the roof structure 11 via an air conditioning duct 14 or the like. In this embodiment, a ceiling is provided obliquely upward from the upper frame 17 of the window glass 15 of the left and right side structures 12 and the sash of the curtain 16. The upper frame 17 has a curtain 1 in the illustrated example.
6 is built in.

The ceiling of the present embodiment is constructed by arranging several profiles in the width direction of the vehicle 1, and has a gently corrugated cross section as a whole. Each of the members arranged in the width direction of the vehicle 1 is arranged to extend in the longitudinal direction of the vehicle 1. A plurality of profiles are connected and arranged in the longitudinal direction of the vehicle 1, but one profile may be sufficient depending on the surface treatment of the profiles. For example, the side small ceiling plate 6 arranged near the left and right ends of the vehicle ceiling can be used in a relatively long dimension in the longitudinal direction of the vehicle 1 by anodizing an aluminum profile.

The number of members arranged in the width direction of the vehicle 1 is set appropriately. That is, although the number of divisions of the profile in the width direction of the vehicle 1 is not particularly limited, in the present embodiment, a central ceiling plate (first ceiling plate) 2 disposed at the center of the vehicle 1 in the width direction;
A pair of left and right second ceiling plates 3 and 3 respectively disposed at both left and right ends thereof, a pair of ceiling light cover plates 5 and 5 provided below the left and right ceiling lamps 13 and 13, and a ceiling light cover plate 5
A pair of third ceiling plates 4, 4 disposed between the first and second ceiling plates 3, a pair of left and right curtain plate ceiling plates 7, 7, which are provided at an angle inside the upper side structure 12; It is provided with a pair of side small ceiling plates 6 and 6 arranged between the plate ceiling plate 7 and the ceiling light cover plate 5.

Each of these ceiling panels (first to third ceiling panels 2,
3, 4, the ceiling light cover plate 5, the side small ceiling plate 6, and the curtain plate ceiling plate 7) are formed of a profile as described above.
Note that the ceiling light cover plate 5 is formed of a translucent material because it is necessary to transmit the light of the ceiling light 13.
Specifically, an extruded profile of milky white polycarbonate is used. Also, the profile (the third ceiling plate 4 in the illustrated example) disposed in the air conditioner outlet 14a is made of polycarbonate for preventing dew condensation. For the ceiling panels other than these, aluminum profiles are used.

As shown in FIGS. 3 to 7, each section is provided with a plate-shaped base portion B, and a cross section in which a plurality of fins F, F. It is shaped. By adopting a cross-sectional shape in which a plurality of fins F are provided on the base portion B, the fins F exert a rib effect, and the rigidity of the ceiling plate can be increased.

In the illustrated example, the base portion B of the central ceiling plate 2 and the curtain ceiling plates 7 and 7 has a linear flat plate shape.
Each base portion B of the third ceiling plate 4, the ceiling light cover plate 5, and the side small ceiling plate 6 is formed to be curved in a curved shape. Note that the base portion B of the second ceiling plate 3 is also slightly curved. The end of the second ceiling plate 3 near the center ceiling plate 2 is formed in a flat plate shape so as to be overlapped with the base portion B of the center ceiling plate 2. Specifically, the side small ceiling plate 6 is curved in a gentle arc shape bulging upward, and the ceiling light cover plate 5 bulges downward so as to be continuous with the arc of the side small ceiling plate 6. The third ceiling plate 4 and the second ceiling plate 3 are formed into a ceiling lamp cover plate 5.
Is slightly bulged upward so as to be continuous with the circular arc. In this way, a ceiling with a waveform is formed as a whole. Since the base portion B itself has a curved shape, rigidity in the longitudinal direction is ensured, and it becomes possible to use the base portion B relatively long without a reinforcing material.

The height (projection length) of the fin F provided on the base portion B, the inclination angle (projection direction) with respect to the base portion B, the pitch between the fins F, and the like are appropriately set. can do. In this embodiment, as shown in FIG. 3, the fin F of the central ceiling plate 2 is formed such that the downwardly protruding length is long at the central portion in the left-right direction and slightly shorter as going outward in the left-right direction. . Therefore, the leading end (lower end) of each fin F is disposed on a gentle arc that swells downward (see the dashed line in FIG. 1). The fins F of the central ceiling plate 2 are formed to be inclined outward in the left-right direction of the vehicle 1. This is to improve the flow of air by the fan H provided above the central ceiling plate 2.

On the other hand, on each ceiling plate (profile) other than the center ceiling plate 2, fins F are formed at substantially equal intervals in a direction substantially perpendicular to the base portion B. The tip of each fin F is formed in a virtual arc shape. Further, as shown by the dashed line in FIG. 1, the tip of each fin F of each section is formed so as to be arranged on a gentle waveform arc.
After the sections are installed on the vehicle structures 11, 12, the arcs formed by the tips of the fins F of the adjacent sections are smoothly connected.

The curtain ceiling plate 7 and the side small ceiling plate 6 are attached to the side structure 1.
The fins F are formed such that the projecting dimension of the fins F becomes shorter toward the second side. In particular, the length of the fin F of the curtain plate ceiling plate 7 is considerably shortened, and the lower end portion of the curtain plate ceiling portion 7 arranged on the cargo rack 18 side in the state of being attached to the vehicle structures 11 and 12 is almost completely removed. It is flat. This is to prevent the dust and the like from accumulating on the fins F and the balance with the interior materials on the left and right side surfaces of the vehicle 1. In addition, as shown in FIG.
Since it is arranged at an angle to open the groove between it downward,
Dust is hardly accumulated on the fins F.

By the way, on the base portion B of each section, mounting pieces M for attaching the section to the vehicle structures 11 and 12 can be integrally formed at the left and right ends. That is,
A mounting piece M that can be mounted on the air-conditioning duct 14 or the bracket B on the vehicle structure 11, 12 may be formed. For example,
The second ceiling plate 3 of FIG. 4 is formed with flat mounting pieces M, M at both left and right ends, and the side small ceiling plate 6 of FIG. Plate-shaped mounting pieces M, M having a substantially L-shape or the like are formed.

Air-conditioning ducts 14, 14 are provided at the left and right ends of the vehicle 1 at the center in the width direction with the fan H and the like interposed therebetween. The second ceiling plate 3 is provided on each lower end surface of the air conditioning duct 14 so as to overlap. Since the base portion B of the second ceiling plate 3 is formed in a curved shape along the bottom surface of the air conditioning duct 14, the base portion B of the second ceiling plate 3 can be superposed on the bottom surface of the air conditioning duct 14. Then, plate-shaped mounting pieces M formed on both left and right end portions of the second ceiling plate 3 are fixed to the bottom surface of the air conditioning duct 14 by screws.

On the other hand, the central ceiling plate 2 arranged at the center in the width direction of the vehicle 1 is provided so as to be bridged between the left and right air conditioning ducts 14. At this time, the left and right ends of the base portion B of the central ceiling plate 2 are superimposed on the mounting pieces M on the inner side in the left and right direction of the second ceiling plate 3 (fan H side). Note that the center ceiling plate 2 is provided with a hinge 21 at one end in the left-right direction, and it is preferable that the hinge 21 be mounted so as to be opened and closed appropriately around the hinge 21. Thus, the central ceiling plate 2 can be used as an inspection lid. Since the aluminum extruded profile with fins F is used, the panel alone has rigidity,
The inspection lid can be configured without requiring special reinforcement.

Left and right air conditioning ducts 1 are provided on the central ceiling plate 2.
An appropriate opening (air passage) 22 is formed in order to secure an air flow passage for the fan H disposed between the fan 4 and the fan 14. This is performed by cutting off a required area of the base portion B of the central ceiling plate 2. Thus, only the fin F can be left in a louver shape. Since the fans F, the speakers S, and the like are arranged at predetermined intervals along the longitudinal direction of the vehicle 1, some of the cuts of the base portion B are formed at intervals in the longitudinal direction in accordance therewith. In addition, the width dimension in the left-right direction of the cut portion is appropriately changed depending on the device disposed above the cut portion.

By the way, the ceiling plates 2 and 3 made of a profile may be attached to the air-conditioning duct 14 and the like provided on the roof structure 11 of the vehicle 1 as described above. It can be attached to the ceiling boards 2 and 3 in advance, and can be attached to the roof structure 11 of the vehicle 1 as a unit. In this way, the assembly can be performed in a downward operation, and it is only necessary to finally attach the vehicle to the vehicle structure 11, so that the construction is extremely easy. In addition, the number of adjustments on site is reduced, and adjustment with other related works can be unnecessary, which is preferable.

Specifically, in this embodiment, after the second ceiling plate 3 and the central ceiling plate 2 are attached to the air-conditioning duct 14 and the like, the curtain rails 11a, 11a at the bottom of the roof structure 11 are finally formed as a unit. It is installed with bolts.

Thereafter, a part of the third ceiling plate 4 is superimposed on an end of the second ceiling plate 3 on the outer side in the left-right direction (the side structure 12 side) and screwed. The screw is disposed in the groove between the fins F, and is attached to the bottom surface of the air conditioning duct 14 with the base portion B superimposed on the mounting piece M on the outer side in the left-right direction of the second ceiling plate 3. Since the bottom surface of the left and right outer ends of the left and right air conditioning ducts 14 is the air outlet 14a of the air conditioner,
Corresponding to this portion, the base portion B of the third ceiling plate 4 is appropriately cut along the longitudinal direction.

The ceiling light cover plate 5 is a component of the ceiling light 13 and is attached together with the ceiling light 13 to the curtain rail 11a of the roof structure 11 via the bracket B.
Note that the ceiling lamp 13 has a downwardly substantially U-shaped cover 13.
a, in which a fluorescent lamp 13b is arranged along the longitudinal direction of the vehicle 1. In order to facilitate replacement of the fluorescent lamp 13b, the ceiling light cover plate 5 is attached to the lower opening of the cover 13a so as to be openable and closable. Moreover, a packing 13c is arranged between the cover 13a and the ceiling light cover plate 5.

The small side ceiling plate 6 is mounted via a bracket B for mounting the ceiling light cover plate 5 and brackets B (Bc) arranged at the upper left and right corners of the vehicle structures 11 and 12. Can be That is, the mounting pieces M, M formed on both left and right end portions of the side small ceiling plate 6 are screwed by overlapping the ends of the brackets B.

The curtain ceiling plate 7 has a lower end fixed to the upper frame portion 17 of the glass sash, and an upper end fixed to one of the mounting pieces M of the side small ceiling plate 6 by screws. In order to allow the base end of the shelf receiving portion 18a to pass through, a substantially rectangular notch is formed at the corresponding lower end of the lower end of the curtain plate ceiling plate 7 so as to open downward.

Incidentally, the central ceiling plate 2 and the second ceiling plate 3
Is divided into a plurality of pieces in the longitudinal direction with the advertisement hanging K interposed therebetween. The advertisement hanging K is provided between the left and right air conditioning ducts 14 and 14 and provided on the bottom surface of the air conditioning duct 14 as shown by a two-dot chain line in FIG. That is, after the upper part of the advertisement hanging K is screwed to the bottom surface of the air-conditioning duct 14, the central ceiling plate 2 and the like are arranged at both front and rear ends with the advertisement hanging K interposed therebetween.

At both left and right ends of the advertisement hanging K, hanging leather rod receivers U are provided. The suspension leather bar receiver U has an inverted L-shape. One piece U1 is attached to the upper curtain rail 11a of the roof structure 11, and the other piece U2 is disposed along the lateral side of the air conditioning duct 14 in the left-right direction.

On the other hand, the connection of the side small ceiling plate 6 in the longitudinal direction is as follows.
As shown by a two-dot chain line in FIG. 2, the backing metal 60 is overlaid on the upper surface (back surface) of each base portion B at the connection end of the side small ceiling plate 6 and screwed. At this time, by arranging the screw in the groove between the fins F, the screw can be made inconspicuous. In addition, by adjusting the gap (joint width) between the connecting portions of the front and rear ceiling plates 6 and 6, it is possible to absorb variations in dimensions peculiar to the vehicle structure. Even if the joint width is increased, the fins F of the ceiling plate 6 can make the joints inconspicuous. Similarly, even if a small gap is left between the side walls at both ends in the longitudinal direction of the vehicle 1 and the ceiling plate, the gap can be made inconspicuous by the fins F. In other words, according to the present invention, even if the joint width is increased, the joint width is not conspicuous, so that it is easy to absorb the variation in the dimensions specific to the vehicle structure. In addition, the pitch of a screw can also be lengthened since the fin with the curved shape was used for the ceiling board.

In addition, since the extruded profile with fins F is used, even if the screw head is installed without hiding it, the head sinks into the groove between the fins F, so that there is an inconvenience in design. There is no risk of occurrence.

As described above, in the state where the ceiling is constituted by each of the profiles, the fins F adjacent to each of the profiles continuously change, so that the entire ceiling surface has a gentle waveform. Moreover, since the fins F are arranged along the longitudinal direction of the vehicle 1, the fin F has a neat design.

When the ceiling is installed, the ceiling light 13
The portion of (the ceiling light cover plate 5) is disposed slightly below other portions. Therefore, the central ceiling plate 2 can be illuminated. Moreover, since light is emitted through the fins F, reflection and indirect lighting effects can be expected. In addition, soft reflection can be obtained with respect to external light without shining on the surface.

[0044]

As described in detail above, according to the railcar ceiling structure of the present invention and the profile used therefor, the number of parts and the number of work steps can be reduced, and the railcar ceiling can be efficiently mounted with a simple structure. Can be constructed. In addition, it is possible to provide a ceiling structure which is easy to absorb variations in dimensions peculiar to the vehicle structure and which is very excellent in design effect. If the unit method is adopted, the number of assembly steps can be reduced, and the cost can be significantly reduced.
