JPS609096Y2 - Passenger train ceiling structure - Google Patents

Description

[Detailed explanation of the idea] This invention relates to the ceiling structure of a passenger train.

In the conventional ceiling structure of passenger trains, a ceiling board was first pasted on the inner surface of the roof, and then ceiling equipment such as air conditioning ducts, ceiling lights, and speakers were individually attached to the underside of the ceiling board. It must be done in several stages,
Production time was getting longer.

In addition, since the ceiling panel is made up of a smooth flat plate or a curved surface, when ceiling equipment such as air conditioning ducts, ceiling lights, and speakers are installed, the ceiling equipment will protrude, making the interior unattractive and undesirable for passengers. There were drawbacks such as negative psychological effects.

In view of the above points, the present invention configures the ceiling equipment as multiple units, attaches the units to a support attached to the roof structure, and makes the bottom surface of the unit flat, so that the bottom surface of the unit forms the ceiling surface. By doing so, the purpose is to simplify the manufacturing work and shorten the working time, as well as to make the ceiling surface flush with the ceiling surface and improve the appearance of the ceiling surface.

Next, the present invention will be explained with reference to a conventional example shown in the drawings and an embodiment of the present invention.

Figure 1 is a sectional view showing the ceiling structure of a conventional passenger train, Figure 2 is a sectional view showing an embodiment of the ceiling structure of the present invention, and Figure 3 is a sectional view showing an embodiment of the ceiling structure of the present invention.
The figure is a plan view showing the ceiling surface of the ceiling structure shown in Figure 2,
This figure is a plan view showing the ceiling surface of another embodiment of the ceiling structure according to the present invention, and FIG. 5 is a sectional view of FIG. 4.

A conventional ceiling structure will be explained with reference to FIG.

In the figure, 1 is a roof component that constitutes a roof, and 2 is a ceiling plate that is attached to the roof component 1.

Reference numeral 3 denotes an air conditioning duct having a heat insulating material 7 provided on the inner surface and a wind outlet 8 at the lower part, and is supported on the roof component 1 by screws 5.

4 is a ceiling light box to which ceiling light 9 is attached;
One side is attached to the air conditioning duct 3, and the other side is attached to the roof component 1 with screws 6.

When assembling this configuration, first the ceiling plate 2 is attached to the roof component 1, and then the air conditioning duct 3 of the ceiling equipment, the ceiling light box 4, etc. are attached.

According to this configuration, the ceiling plate 2 is later attached by installing the air conditioning duct 3 and the ceiling light box 4 of the ceiling equipment in several stages for each equipment.

Therefore, the work becomes extremely complicated and the number of parts increases.

In addition, since the ceiling plate 2 is composed of a smooth flat plate or a curved surface, the air conditioning duct 3 and the ceiling light box 4
This had the disadvantage that the ceiling equipment such as these had a protruding shape that made it look unsightly.

Next, one embodiment of the present invention will be described with reference to FIGS. 2 and 3.

In the figure, the same reference numerals as in the above conventional example indicate the same parts.

Reference numerals 10 and 11 are rails attached to the roof component 1', and two rails are provided each in the longitudinal direction of the structure.

12 is an air conditioning duct unit that can be divided into fixed lengths, 1
3 is a ceiling light unit configured for each ceiling light 9; the air conditioning duct unit 12 is supported on the rail 10 by screws 14 on both sides; the ceiling light unit 13 is mounted on both sides; The part shown in FIG. 1 is mounted on the rails 10 and 11 by means of screws 15.

In this configuration, when performing an assembly operation, the air conditioning duct unit 12 and the ceiling light unit 13 are attached to the rails 10 and 11 using screws 14 and 15 in a single operation.

According to this configuration, the work during assembly is simple and easy, and the number of parts during assembly can be reduced.

Next, another embodiment of the present invention will be described with reference to FIGS. 4 and 5.

In the figures, the same reference numerals as in the above embodiment indicate the same parts.

The configuration of this embodiment differs from the above embodiment as follows:
The mounting is based on the shape of the rails 10' and 11', and the mounting is based on the shape of the air conditioning duct unit 12 and the ceiling light unit 13, which are supported by the rails 10' and 11'. It has a shape with grooves on both sides, and the air conditioning duct unit 12 and ceiling light unit 13 are mounted on the rail 10'.
It has a shape that can be fitted into the grooves 11' and 11'.

In addition, in this embodiment, ceiling light units 1 are installed in several locations.
3, a speaker unit 16 having the same shape as the ceiling light unit 13 is installed.

In this configuration, when performing assembly work, the end face of the vehicle body is left open, and the air conditioning duct unit 12, ceiling light unit 13, and speaker unit 1 are sequentially connected from there.
6 is inserted into the grooves of the rails 10' and 11'.

According to this configuration, the air conditioning duct unit 12, ceiling light unit 13, and speaker unit 16 are supported by being inserted into the grooves of the rails 10' and 11', so there is no need for mounting screws, etc. At the same time, the appearance is good because there are no mounting screws etc. protruding from the ceiling surface.

As explained above, according to the present invention, ceiling equipment such as air conditioning ducts, ceiling lights, and speakers are configured as a unit, and the unit is mounted on a roof structure and supported by being attached to a rail. The work time can be shortened and the number of parts can be reduced.

Furthermore, since the lower surface of the unit is supported so as to be substantially flat, the overall appearance of the ceiling of the cabin is good.
