Description

[Detailed Description of the Invention] The present invention relates to an improvement in the mounting structure of a vehicle interior lighting device suitable for use in vehicles, particularly buses, trains, etc.

Conventionally, when attaching a support member that supports fluorescent tubes to a ceiling lining member in a bus body with a large longitudinal length, it is necessary to hold the heavy support member with your hands while looking up at the ceiling and install it using an appropriate fastening method. was. However, this assembly work required that each supporting member of a predetermined length be temporarily positioned by adjusting its relative position with the surrounding ceiling lining members in advance. The support member did not have a structure that could support the support member by engaging with a member forming a part of the support member. For this reason, during the temporary positioning work, it is necessary to look up at the support member and support it with your hands to prevent it from falling, which greatly reduces the efficiency of the temporary positioning work in the narrow working space inside the vehicle. I had a problem that kept getting worse.

The present invention has been devised in view of the above drawbacks, and its purpose is to provide a support member, which is a component of a vehicle interior lighting device, before fastening it to a ceiling lining member. An object of the present invention is to provide a mounting structure for a vehicle interior lighting device that improves the efficiency of temporary positioning work for adjusting the relative position between a support member and a surrounding ceiling lining member.

In order to achieve such an objective, the present invention provides a vehicle interior lighting system in which fluorescent tubes are arranged, and a ceiling lining member of a vehicle provided with an opening for installing the lighting system, which is arranged in parallel along the edge of the opening. two channel members each having a trapezoidal cross-section and having a space inside and an open bottom surface; a support member that supports the fluorescent tube and has flange portions on both side walls along the channel members; established in
A tongue piece member whose free end is formed to engage with the inclined side wall of the channel member, and cooperates with the channel member to sandwich the edge of the opening and the flange portion, which are arranged on substantially the same plane. The support member is provided with a back-up plate that engages the tongue member with the inclined side wall by inserting the support member into the opening and engaging the tongue member with the inclined side wall before the flange portion is held. The means is characterized in that it is configured to be temporarily positioned on the channel member via a member.

Hereinafter, one embodiment of the present invention will be described in detail.

In FIGS. 1 and 2, reference numeral 1 denotes a channel material having a trapezoidal cross section with a space inside and an opening formed on the lower surface, and one of the two lower surfaces formed by the opening. Ceiling lining member 1 on the bottom surface
5 and extends in the longitudinal direction of the bus body. The resin clip 2 is inserted into the channel material 1 through the opening and is locked to the channel 1. A metal molding 3 forming a back-up plate provided opposite to the channel material 1 extends in the longitudinal direction of the vehicle body and is fixed to the resin clip 2 by a tapping screw 4. Reference numeral 5 denotes a support member disposed in large numbers in the longitudinal direction of the vehicle body, which houses a fluorescent tube 7 and devices necessary for lighting the fluorescent tubes, such as a glow lamp and a transformer. Further, flange portions 2 are provided at both ends of the support member 5.
0 is formed. Reference numeral 6 denotes a tongue member having the function of temporarily positioning the support member 5 on the channel material 1, one end of which is fixed to the support member 5, and the other free end engaged with the inclined side wall of the channel material 1. It is designed to be Then, in the state where the tongue piece member 6 is engaged with the inclined side wall,
The flange portion 20 is set so that its surface is substantially the same as that of the ceiling lining member 15. The resin member 8 is locked to the molding 3 by a claw 9 and extends in the longitudinal direction of the vehicle body. The acrylic cover 10 is a resin member 8
It is press-locked to the molding 3 and covers the lower surface of the fluorescent tube 7, which is the irradiation surface of the fluorescent tube 7. The cover 10 also extends to the end of the fluorescent tube 7, as shown in FIG. A connecting plate 11 made of the same material as the cover 10 is placed between the adjacent covers 10.
It is disposed with a gap between the cover 10 and the cover 10, and is press-locked to the molding 3 in the same manner as the cover 10. The back plate 12 is bonded to the joint plate 11 and covers the gap between the joint plate 11 and the cover 10. A crossbow 14 is disposed above the joint plate 11 to support the roof plate 13.

In addition, since the cover 10 and the connecting plate 11 are made of the same material, they appear to be connected from the front to the rear of the vehicle, giving a good appearance.
Further, since a gap is formed between the cover 10 and the joint plate 11, even if the cover 10 expands thermally due to the heat of the fluorescent tube 7, no stress is applied to the cover 10. Further, since the connecting plate 11 is located below the crossbow 14 and not below the fluorescent tube 7, it is difficult for illumination light to reach it and the gap between the cover 10 and the connecting plate 11 is difficult to see, which is preferable from an aesthetic point of view.

Since this embodiment is configured as described above, when assembling the support member 5 to the ceiling lining member 15,
First, the support member 5 is inserted into the roof plate 13 through an opening formed in the support member 15. Next, the tongue piece member 6
are engaged with the inclined side walls of both channel members 1 to temporarily position the support member 5. In this state, the fluorescent tube wiring, channel material 1 and ceiling lining member 1
While adjusting the relative position with 5, remove the ceiling lining member 1.
5 and the flange portion 20 are the same, and then remove the molding 3 that is the back-up plate.
The tapping screw 4 is screwed into the resin clip 2 previously accommodated in the space of the channel material 1 through the screw. In this way, the ceiling lining member and the flange portion are flush with each other, and the channel material 1 and the molding 3
sandwiched between. For this reason, the ceiling lining member 1

In the present invention, two channel members each having a trapezoidal cross section are installed side by side along the edge of an opening formed in a ceiling lining member, and the support member on the side opposite to each channel member is provided with an inclination of the channel member. A tongue piece member whose free end can be engaged is provided on the side wall, and before the flange portion is sandwiched between the channel member and the backup plate, a supporting member is inserted into the opening, and the tongue piece member is inserted into the opening. By engaging with the inclined side wall, the support member is temporarily positioned on the channel member via the tongue piece member, so that the support member in the temporary positioning step can be temporarily positioned on the channel member via the tongue piece member. This eliminates the need to support the supporting member from below by hand as in the conventional method, and makes it possible to wire fluorescent tubes, channel members, and ceiling lining while looking up at the ceiling. This has the practical effect of greatly improving the efficiency of relative position adjustment and temporary positioning work with members.
