Description

[Detailed Description of the Invention] "Industrial Application Field" This invention relates to a mounting structure for mounting a fluorescent lamp unit to a ceiling panel in a bus vehicle, for example.

``Prior Art'' As shown in FIG. 4, a conventional mounting device of this type is such that, for example, a fluorescent lamp case 13 is installed on a ceiling panel 11 of a bus vehicle, and a fluorescent lamp 14 is installed inside the fluorescent lamp case 13. Furthermore, as shown in FIG. 5, an inverter 15 and the like for lighting the lamp are installed. These fluorescent lamps 14 and inverter 15
A glove 16 is attached to cover the
Further, moldings 17 are attached to the flange portion of the fluorescent lamp case and both side edges of the globe so as to cover the mounting screws 26 of the fluorescent lamp case 13, extending along the respective longitudinal directions.

As shown in FIGS. 5 and 6, this conventional fluorescent lamp unit mounting structure includes the flange 22 of the fluorescent lamp case 13, the fixing plate part 24 of the molding 17, and, in this example, the fixing bracket 25. are stacked on top of each other and screwed together with screws 26. A flange 2 is attached to the fixed plate portion 24 of the molding 17.
A vertical plate part 27 is integrally provided hanging from the fixed plate part 27 along its longitudinal direction, and a lid part 29 is connected to one end of the fixing plate part 24 by a hinge-like connecting part 28 made of a soft resin material. An upper clamping plate part 31 and a lower clamping plate part 32, which clamp the edge of the globe 16 from above and below, are integrally formed on the side opposite to the vertical plate part 27. That is, the upper clamping plate part 31 is integrated with the fixed plate part 24, and the lower clamping plate part 3
2 is integrally connected to the vertical plate portion 27 via a connecting portion 33 that constitutes a hinge made of soft material.

In this prior art, in order to attach the fluorescent lamp unit to the ceiling plate 21, as described above, the lid body part 2
9 is in the open state, fluorescent lamp case 13, mall 1
7 with screws, and after pressing the edge of the glove 16 to the lower end of the upper holding plate part 31,
While pressing the lower clamping plate part 32 from below, the lid part 29 is closed, and at this time, the lower clamping plate part 3
2, the glove 16 is held.

In this way, in the past, the fluorescent lamp case 13, globe 16, and molding 17 were separated, so first the fluorescent case was screwed to the ceiling plate, and then the molding 17 was screwed together to the flange of the fluorescent lamp case and the ceiling plate. Finally, the glove 16 is attached to the molding 17. In this way, there are three parts to be installed, and the installation workability is poor. Due to the screw fixing, the area around the screw fixing of the molding 17 was deformed, and there was also a problem that the appearance was not good.

In addition, Japanese Utility Model Application No. 61-201955 discloses that the flange of a fluorescent lamp case is sandwiched between the vehicle ceiling plate and the upper plate of the escutcheon, these are fixed to the ceiling plate with screws, and an elastic material is attached to the escutcheon. A first molding is inserted and attached, and the flange of the glove is inserted between the first molding and the escutcheon in an engaged state, and a groove provided in the longitudinal direction in the center of the first molding. It is described that the flange of the glove can be held by fitting a second molding made of an elastic material in an engaged state.

However, it is not easy to insert and install the first molding from one end of the escutcheon after stacking the upper plate of the escutcheon on the flange of the fluorescent light case and fixing it to the ceiling board with screws, especially when the fluorescent light case is long. In some cases, the vehicle body gets in the way and the installation work is difficult.

``Means for solving the problem'' According to this invention, metal rails are stacked and fixed on the flange of the metal case of a fluorescent light unit, the molding is inserted into the rail in advance, and the lid of the molding is opened. In this state, the rails are attached to the ceiling panel of the vehicle with screws. When the lid body is in the closed state, the edge of the glove is held between the upper holding plate and the lower holding plate. Therefore, there is no need to screw the molding, and there is no risk that the screwed portion of the rail will be deformed. Furthermore, even in the case of a long fluorescent light unit such as a bus, the installation work is relatively easy.

``Embodiment'' In FIG. 1, parts corresponding to those in FIGS. 5 and 6 are shown with the same reference numerals, but in this invention, the rail 41 is overlapped with the flange 22 and fixed, and is attached to the ceiling plate 21. . In this case flange 22
It is also possible to use one in which the rail 41 is spot welded. This flange 22, rail 4
1 to the ceiling plate 21 is done with screws 26. The molding 17 is almost the same as that shown in the prior art, and has a fixing plate part 24, a vertical plate part 27, a lid body part 29, an upper clamping plate part 31, and a lower clamping plate part 32, which are integrally constructed. Rail insertion parts 42 are integrally formed on both sides of the upper side of the plate part 24, that is, on the opposite side to the vertical plate part 27. The rail 41 is a rail made by folding both legs of a U-shaped plate outward, and a rail insertion part 42 is inserted into the folded part of the leg. The rail insertion portion 42 also serves as a rail shielding portion that hides the rail 41 from the outside.

Further, a hole 43 through which the head of the screw 27 passes is formed in the fixing plate portion 24. That is, in a state where the molding 17 is inserted and attached to the rail 41 by the insertion part 42, the lid part 29 is opened and the rail 41 and flange 22 can be screwed to the ceiling plate 21 with the screws 26 through the holes 43.

With such a configuration, the molding 17 is attached to the rail 41, the glove 16 is inserted between the upper clamping plate part 31 and the lower clamping plate part 32 of the molding 17, and when the lid body part 29 is temporarily fixed while being open. The rail 41 fixed to the case 13 can be attached to the ceiling plate 21, and the lid body part 29 can be covered, making the attachment work easier than in the conventional case.

As shown in FIG. 2, the rail 41 may be constructed by bending its U-shaped legs mutually inward, and in this case, the rail insertion portion 42 is adapted to engage with the rail 41 from the inside. The rail 41 may be engaged and held between the fixed plate portion 24 and the fixing plate portion 24.
The structure of the rail is as shown in Figure 3.
As shown in FIG. 1, the U-shaped legs may not be folded back, but may be bent outwards, and this portion may be sandwiched between the rail insertion portion 42 and the fixing plate portion 24.

"Effect of the invention" As mentioned above, according to this invention, the rail 4
The molding 17 can be inserted into the molding 17, and the rail 41 and the case 13 can be attached to the ceiling plate 21 with the globe 16 attached to the molding 17, and the number of parts is smaller than that of the conventional one. The installation work of the fluorescent lamp unit is easy. Furthermore, since the molding 17 is not screwed, there is no risk of the molding being deformed.
