Description

  The present invention relates to a vehicle ceiling rail member that fixes a support such as a stanchion extending vertically in a passenger transport vehicle room to the ceiling.

  In passenger cabins such as buses, trains, ships and airplanes, there are provided stanches (hereinafter referred to as supports) that can be held by passengers in order to maintain their posture. The support tool extends in the vertical direction, and the upper end thereof is fixed to the ceiling.

  A rail structure is known as one of the structures for fixing the support to the ceiling (see, for example, Patent Document 1). In the rail structure, the upper end of the support is fixed to the ceiling via a rail member (ceiling rail) that extends outside the center in the vehicle width direction of the ceiling and extends in the vehicle length direction. According to the rail structure, since a plurality of supports can be fixed to one rail member, the number of parts can be reduced and the layout of the plurality of supports can be facilitated. .

  Further, the rail member may have not only a function of fixing the support, but also a function of supporting a ceiling trim and a cooler duct constituting the ceiling. That is, the end of the ceiling trim or the cooler duct is pressed using a rail member extending over substantially the entire length of the ceiling in the vehicle length direction. Thus, by adding various functions to the rail member, the entire vehicle ceiling structure can be simplified.

Is done.

[2. effect]
(1) The rail member 1 is provided with a side surface portion 16 to which the room light 5 is attached. Therefore, the rail member 1 can serve not only the function of fixing the stanchion 3 to the ceiling 2 but also the function of providing a space for mounting the interior light 5. As a result, it is not necessary to prepare a dedicated space for attaching the interior light 5 at the center of the ceiling 2 in the vehicle width direction, so that the entire structure of the ceiling 2 can be simplified. Therefore, the number of assembling steps and the assembling cost of the ceiling 2 can be reduced.

  Moreover, according to the rail member 1, since the interior lamp 5 is attached to the side part 16, the interior lamp 5 can be arrange | positioned in space saving. Thereby, the freedom degree of the layout of the apparatus attached to the ceiling 2, such as a speaker and a ventilation fan, for example can be improved. Moreover, since the interior light 5 can be omitted from the ceiling trim 23, the structure of the ceiling trim 23 can be simplified, and the appearance of the ceiling trim 23 can be improved.

  (2) The rail member 1 is provided with a first flange 12 projecting in the width direction from the first fixing portion 14. The first flange portion 12 is disposed so that the end portions of the cooler duct 22 and the ceiling trim 23 are sandwiched between the ceiling frame 21 when the first fixing portion 14 is fixed to the ceiling frame 21. Thereby, at the same time as fixing the rail member 1 to the ceiling frame 21, each end of the cooler duct 22 and the ceiling trim 23 can also be fixed. Therefore, the assembly man-hour of the ceiling 2 can be reduced. Moreover, the substantially whole surface of the upper surface of the 1st collar part 12 contact | abuts with the cooler duct 22 and the ceiling trim 23, and can support the cooler duct 22 and the ceiling trim 23 stably.

  (3) The rail member 1 is provided with a second flange 13 protruding in the width direction from the second fixing portion 15. The 2nd collar part 13 protrudes in the width direction outer side of the rail member 1 rather than the side part 16, and functions so that the side part 16 may be hidden with respect to a passenger | crew. Thereby, the interior light 5 can be made invisible directly from the passenger. Therefore, according to the rail member 1, the light of the interior lamp 5 can be used as indirect illumination for the occupant, and the indoor aesthetics can be enhanced.

  (4) The rail member 1 is formed of an aluminum material. Therefore, the rail member 1 has a relatively high thermal conductivity, and can efficiently dissipate the room light 5 installed on the side surface portion 16.

[3. Modified example]
Regardless of the embodiment described above, various modifications can be made without departing from the spirit of the present embodiment. Each structure of this embodiment can be selected as needed, or may be combined appropriately.

  In the present embodiment, the case where the rail member 1 fixes the stanchion 3 to the ceiling 2 is exemplified. However, the object fixed by the rail member 1 is at least a pipe-like shape extending in the vertical direction in the passenger transport vehicle. It may be a columnar member and is not limited to the stanchion 3. For example, instead of the stanchion 3, a support tool for supporting the suspended leather, a support tool for hanging advertisements, or the like may be applied.

Moreover, although the case where the rail member 1 was extended along the vehicle length direction was illustrated in this embodiment, the rail member 1 should just extend to the ceiling 2 at least, and the extending direction is a vehicle length direction. It is not limited to.
In the present embodiment, the rail member 1 is formed in a left-right symmetrical cross-sectional shape, and the first flange portion 12 and the second flange portion 13 are both provided in a pair on the left and right. It does not have to be formed in a symmetric cross-sectional shape. For example, the 1st collar part 12 and the 2nd collar part 13 may be provided in either one of right and left.

  Furthermore, in this embodiment, although the case where the room light 5 was attached to each of the left and right side surface parts 16 and 16 was illustrated, the room light 5 is, for example, one side surface part provided on the center side in the vehicle width direction of the vehicle. 16 may be attached. Moreover, the number and arrangement | positioning of the interior light 5 and the stanchions 3 can be suitably set as needed.

  Moreover, in this embodiment, although the case where the 1st fixing | fixed part 14 was fixed to the ceiling 2 with the volt | bolt 6a and the nut 6b was illustrated, the fixing method of the 1st fixing | fixed part 14 and the ceiling 2 can be changed. For example, the first fixing part 14 and the ceiling 2 may be fixed by processing a female screw in the hole 21h of the ceiling frame 21 so that the hole 21h and the bolt 6a are screwed together. In this case, the nut 6b can be omitted.

  In the present embodiment, the upper end 3 a of the stanchion 3 is fixed to the second fixing portion 15 via the joint member 4. For example, the upper end 3 a of the stanchion 3 is directly fixed to the second fixing portion 15. Thus, the joint member 4 may be omitted.
