As will be described later, by engaging the stopper 16b with the slit 16a, even when the fitting portion 13 is disengaged, the engagement of the engaging portion 16 is maintained, and the cover 12 is separated from the main body 11. It can prevent falling.

  Next, each of the above components will be described. The main body 11 of the case body 10 is formed in a flat shape as a whole, and one end thereof is formed in an arc shape and the other end is formed in a straight line shape. On the upper part of the main body 11, a main body fixing bracket 22 for fixing to the indoor ceiling is provided. The cover 12 is formed in substantially the same shape as the main body 11 by a thin plate member. The air cleaning unit 14 has an air blowing nozzle 17 opened to the side of the main body 11. The LED lighting unit 15 is attached to the inner cover 18 of the main body 11.

  The inner cover 18 is provided with two slits 16 a positioned on the arcuate end of the main body 11 and two guide bar holes 19 positioned in the middle of the main body 11. The cover 12 has two outlets 20 that are aligned with the air outlet nozzle 17 of the air cleaning unit 14 and the guide bar hole 19 of the main body 11 when the cover 12 is attached to the main body 11. A guide bar 21 is provided. The guide bar 21 is inserted into the guide bar hole 19 even when the cover 12 and the main body 11 are separated by a predetermined distance. One or three guide rod holes 19 and three or more guide rods 21 can be provided.

  As shown in FIG. 4, the fitting hole 13 a and the fitting piece 13 b of the fitting portion 13 are arranged at positions that align with the left and right in FIG. 3 when the cover 12 is assembled to a predetermined position of the main body 11. ing. Then, by assembling the cover 12 at a predetermined position of the main body 11, the fitting piece 13b is fitted into the fitting hole 13a, and the main body 11 and the cover 12 are integrated.

  In order to engage or disengage the fitting hole 13a and the fitting piece 13b of the fitting portion 13, first, the fitting hole 13a and the fitting piece 13b are separated from each other by a predetermined distance. It is necessary to move relative.

  In this embodiment, as shown in FIG. 5, when fitting the fitting hole 13a and the fitting piece 13b or releasing the fitting, the fitting hole 13a and the fitting piece 13b are relatively separated from each other. The minimum distance to be made is called a fitting allowance K1. In the case of the present embodiment, the fitting allowance K1 is substantially the same as the length from the base 13c to the tip 13d of the fitting piece 13b.

  As shown in FIG. 4, the slit 16 a of the engaging portion 16 in the main body 11 and the stopper 16 b in the cover 12 are arranged at positions that align vertically when the cover 12 is assembled to the main body 11. . Thus, when the cover 12 is assembled to the main body 11, the stopper 16b is engaged with the slit 16a. As will be described later, the engagement portion 16 is configured such that its engagement margin K2 (see FIG. 7) is larger than the fitting margin K1 (see FIG. 5) of the fitting portion 13.

  As shown in FIG. 6, on both sides of the slit 16a, slits 16c and 16c parallel to the slit 16a are provided close to the slit 16a. As a result, the actual flesh portion between the central slit 16a and the slits 16c, 16c on both sides can be elastically deformed, and after the groove width b1 of the slit 16a is elastically expanded, the original dimensions are restored. be able to.

  Further, as shown in FIG. 7, the stopper 16b of the engaging portion 16 has a rod-shaped portion 16d having a predetermined length and an arrowhead-shaped head portion 16e provided at the tip of the rod-shaped portion 16d. The maximum dimension b2 of the part facing the slit 16a of the head 16e is larger than the groove width b1 of the slit 16a (b2> b1).

  Here, by pushing the head portion 16e into the slit 16a, the groove width b1 of the slit 16a is elastically expanded by the head portion 16e. As a result, the head portion 16e of the stopper 16b can penetrate the slit 16a and enter the inner space of the inner cover 18. In addition, after the head portion 16e enters the inner space of the inner cover 18, the groove width b1 of the slit 16a is elastically restored to the original dimension, and the rod-shaped portion 16d is inserted into the slit 16a, and the head portion 16e. Is engaged with the slit 16a.

  Note that the stopper 16 b of the engaging portion 16 is provided in a position in the internal space of the case body 10 that does not face the air inlet (not shown) of the air cleaning unit 14 and the air blowing nozzle 17. The LED illumination unit 15 is provided between the two stoppers 16b.

  Here, in order to engage or disengage the slit 16a and the stopper 16b, the dimension for elastically expanding the groove width b1 of the slit 16a is referred to as an engagement allowance K2. In the present embodiment, the engagement allowance K2 is the difference between the maximum dimension b2 of the portion of the arrowhead-shaped head portion 16e facing the slit 16a and the groove width b1 of the slit 16a. That is, the engagement allowance K2 = b2-b1.

  In the present embodiment, the engagement margin K2 of the engagement portion 16 is configured to be larger than the engagement margin K1 of the fitting portion 13 (K2> K1). As a result, as shown in FIGS. 8 to 10, the engagement portion 16 maintains the engagement even after the cover 12 is separated from the main body 11 due to the fitting portion 13 being disengaged. Thereby, even after the fitting part 13 is removed and the cover 12 is separated from the main body 11, the cover 12 is connected to the main body 11 by the engaging part 16.

  Even when the cover 12 is separated from the main body 11, the distance between the cover 12 and the main body 11 is kept within a predetermined distance by the engaging portion 16, so that the guide bar 21 of the cover 12 is attached to the main body 11. The guide rod hole 19 is inserted.

  Next, a procedure for attaching the cover 12 to the main body 11 will be described. In addition, the main body 11 shall be attached to the indoor ceiling. Further, the length of the guide bar 21 of the cover 21 is set to be longer (larger) than the length of the stopper 16 b of the engaging portion 16. Here, first, the cover 12 is lifted corresponding to the main body 11, the guide bar 21 is inserted into the guide bar hole 19 of the main body 11, and the cover 12 is lifted as it is. Thereby, the head portion 16 e of the stopper 16 b of the engaging portion 16 passes through the slit 16 a of the main body 11 and is inserted into the inner space of the inner cover 18.

  In this state, the cover 12 can move to some extent in the vertical direction, but the movement is restricted by the engaging portion 16 and the guide bar 21 in the horizontal direction. Therefore, when the cover 12 is continuously lifted, the fitting piece 13 b of the main body 11 is fitted into the fitting hole 13 a of the cover 12, and the cover 12 is integrally attached to the main body 11 by fitting of the fitting portion 13.

  According to the LED lighting apparatus 1 of the present embodiment, the main body 11 and the cover 12 are integrally assembled by the fitting portion 13, and the engaging portion 16 provided between the main body 11 and the cover 12 is engaged. . The engagement margin K2 of the engagement portion 16 is configured to be larger than the engagement margin K1 of the fitting portion 13. Therefore, even if the fitting part 13 is detached due to some cause such as vibration or impact and the cover 12 is separated from the main body 11, the engagement of the engaging part 16 is maintained.

  Thereby, even if the cover 12 is separated from the main body 11, the cover 12 remains connected to the main body 11 by the engaging portion 16, so that the cover 12 can be prevented from dropping from the main body 11. In addition, since the cover 12 can be prevented from being greatly shaken by the vibration of the vehicle by the engagement of the engaging portion 16, the feeling of anxiety of the occupant can be suppressed. Further, since it is not necessary to connect the cover 12 to the main body 11 with a hanging strap or a chain as in the conventional case, the number of parts can be reduced and the work of attaching the parts can be omitted, and the work can be simplified and the cost can be reduced. become.

  Further, after the cover 12 is separated from the main body 11, the two guide bars 21 provided at a predetermined interval in the cover 12 remain inserted in the guide bar holes 19 of the main body 11. As a result, it is possible to further suppress the cover 12 from greatly shaking and to further suppress anxiety of the vehicle occupant. In particular, since the LED lighting device 1 is attached to the inside of a vehicle, even if the cover 12 is separated from the main body 11, it is possible to prevent an occupant from feeling uneasy, which is very effective.

  Further, by deforming the side portion of the cover 12 from the outside to the inside, even when the fitting portion 13 is removed and the cover 12 is separated from the main body 11, the engagement of the engagement portion 16 can be maintained. As shown in FIG. 10, the internal structure of the main body 11 and the cover 12 can be visually recognized in a state where the cover 12 is separated from the main body 11 by a predetermined distance W. Thereby, cleaning and maintenance of the air intake port of the air cleaning unit 14 and the LED lighting unit 15 can be facilitated.

  When the fitting portion 13 is disengaged and the engagement portion 16 is kept engaged, the distance W between the front end of the cover 12 and the main body 11 is the length of the stopper 16b of the engagement portion 16. It is determined by the relationship between the thickness of the guide bar 21 and the hole diameter of the guide bar hole 19. For this reason, when the length of the stopper 16b of the engaging portion 16 and the positional relationship between the stopper 16b and the guide rod 21 are the same, the larger the clearance between the guide rod hole 19 and the guide rod 21, the larger the opening dimension W becomes. growing. Therefore, the opening dimension W can be easily adjusted by changing the clearance between the guide bar hole 19 and the guide bar 21.

  Further, since the guide rods 21 and 21 are inserted into the guide rod holes 19 and 19, a part of the weight of the cover 12 is supported. Even if the fitting force (holding force) is relatively small, the cover 12 can be supported. Thus, since the fitting force of the fitting part 13 can be made small, the force required for fitting the fitting part 13 can be made comparatively small. Therefore, the fitting operation between the fitting hole 13a of the fitting portion 13 and the fitting piece 13b is facilitated.

  Further, the stopper 16b of the engaging portion 16 is provided in a portion of the internal space of the case body 10 that does not face the air blowing nozzle 17 and the air inlet of the air cleaning unit 14, so that the stopper 16b It is possible to prevent the blowout and intake air from being inhibited.

  Furthermore, two stoppers 16b of the engaging portion 16 are provided, and the LED illumination unit 15 is disposed between the stoppers 16b. Therefore, even when the cover 12 is separated from the main body 11, the LED illumination unit 15 is Held in position. Thereby, indoor lighting can be secured.
