Of the side case 26 and the clips 35a, 35b,. The side case 26 is detachably connected.

  As shown in FIGS. 4A to 4C, various variations of the design surface 42 of the ceiling case 27 are conceivable. For example, the translucent portions 43a and 43b are each composed of a rectangular portion that extends over the entire rotation portions 31a and 31b (FIG. 4A), and the translucent portions 43a and 43b are each composed of a plurality of elongated pieces. And the like (FIG. 4 (b)), the translucent portions 43a and 43b are each composed of a plurality of circular portions (FIG. 4 (c)), and the like.

Next, the operation of the present embodiment having such a configuration will be described.
First, the operation when the ceiling case 27 is removed when the car ceiling 15a is renewed will be described.

  First, the clips 35a, 35b,... Are removed from the holes 34a, 34b,... Of the ceiling case 27 and the holes 36a, 36b,. At this time, the rotating portions 31a and 31b of the design surface 42 of the ceiling case 27 rotate downward with their own weight with respect to the fixed portion 28, and move to the vertical position shown in FIG.

  Next, the fastening member 46 is removed, and the columns 30 a and 30 b are removed from the reinforcing members 22 g and 22 h of the ceiling plate 23. Thereby, the ceiling case 27 is removed from the ceiling board 23. Thereafter, the ceiling case 27 is carried out from the car 15 to the landing. At this time, since the pair of handles 39a and 39b are provided on the fixing portion 28 of the design surface 42 of the ceiling case 27, the ceiling case 27 can be transported safely and easily.

  Next, the action when the new ceiling case 27 is attached after the ceiling case 27 is removed will be described.

  First, a new ceiling case 27 is prepared, and this ceiling case 27 is carried into the car 15 from the landing. Next, the pair of handles 39a and 39b are gripped, and the ceiling case 27 is lifted upward and moved to the ceiling plate 23 side. Next, the columns 30 a and 30 b are attached to the reinforcing members 22 g and 22 h of the ceiling plate 23 by the fastening member 46. In this way, the ceiling case 27 is connected to the ceiling plate 23 via the support columns 30a and 30b. At this time, the rotating portions 31a and 31b of the design surface 42 of the ceiling case 27 are in a vertical position as shown in FIG.

  Next, each rotation part 31a, 31b is rotated upward and moved to the horizontal position shown in FIG. In this state, the holes 36a, 36b, ... of the side case 26 and the holes 34a, 34b, ... of the ceiling case 27 are connected by the clips 35a, 35b, .... At this time, since it is only necessary to fit each clip 35a, 35b,..., There is no need to use a tool, and particularly advantageous when the space between the side case 26 and the side plate of the car 15 is narrow. is there. As a result, the ceiling case 27 and the side case 26 are connected to each other, and the rotating portions 31 a and 31 b are held in a horizontal position with respect to the fixed portion 28.

  In this way, the ceiling case 27 can be replaced during the renewal construction of the car ceiling 15a.

  Thereafter, with the fixed portion 28 of the design surface 42 of the ceiling case 27 and the rotating portions 31a and 31b being in a horizontal state (horizontal position shown in FIG. 2), the gap 47a between the fixing portion 28 and the rotating portions 31a and 31b. 47b is preferably sealed with joints 38a and 38b as appropriate (see FIG. 5).

  As described above, according to the present embodiment, the ceiling case 27 and the ceiling plate 23 are detachably connected by the fastening members 46 via the support columns 30a and 30b extending vertically, so that the car ceiling 15a is renewed. The ceiling case 27 can be easily replaced during construction.

  Further, according to the present embodiment, the design surface 42 of the ceiling case 27 includes the fixed portion 28 to which the support columns 30a and 30b are attached, and the rotating portions 31a and 31b that are rotatably connected to the fixed portion 28. Therefore, a sufficient construction space can be secured when the car ceiling 15a is renewed. In other words, by rotating the rotating portions 31a and 31b of the design surface 42 of the ceiling case 27 downward with respect to the fixed portion 28 to the vertical position, the work of removing the columns 30a and 30b from the ceiling plate 23 is easily performed. can do.

  Furthermore, according to the present embodiment, the ceiling case 27 and the side case 26 are provided with the clips 35a, 35b,... Inserted into the holes 34a, 34b,. The side case 26 and the ceiling case 27 can be easily attached and detached without using a tool or the like.

  Furthermore, according to the present embodiment, the gap between the fixed portion 28 and the rotating portions 31a, 31b in a state where the fixed portion 28 of the design surface 42 of the ceiling case 27 and the rotating portions 31a, 31b are horizontal to each other. Since 47a and 47b are sealed by joints 38a and 38b, the light from the light emitters 25a and 25b does not leak from the gaps 47a and 47b between the fixed portion 28 and the rotating portions 31a and 31b.

  Furthermore, according to the present embodiment, since the handles 39a and 39b are attached on the fixing portion 28 of the design surface 42 of the ceiling case 27, the operator holds the ceiling case 27 when the ceiling 15a is renewed. The ceiling case 27 can be easily replaced by lifting.
