  FIG. 9 is a diagram for explaining the operation of attaching the cover 200 in the configuration of the cover attaching device of FIG. Hereinafter, the attaching operation of the cover 200 will be described with reference to FIGS.

(Step 1)
In step 1 of FIG. 9, the slider 310 receives a tensile force f from the spring 400. At the same time, the slider 310 engages with the storage-side engagement portion 322 by the slider-side engagement portion 312, so that the slider-side receiving portion 311 and the slider-side receiving portion 311 are moved from the storage port 321 against the tensile force f from the spring 400. It is stationary with the contact portion 313 exposed.

(Step 2)
In step 2, when the slider-side receiving portion 311 receives the cover-side protruding portion 201a, the slider 310 is disengaged from the storage-side engaging portion 322 by the slider-side engaging portion 312. That is, as shown in Step 2 of FIG. 9, the slider-side engagement portion 312 is detached from the storage-side engagement portion 322 of the storage portion 320.

(Step 3)
In step 3, the slider 310 abuts on the left side surface of the cover-side protruding portion 201 a by the tensile force f when the slider 310 is disengaged from the slider-side engaging portion 312 and the storage-side engaging portion 322. The cover-side protruding portion 201a is moved from the storage port of the storage portion 320 to the inside while being in contact with the head. If the movement of the cover side protruding portion is described in the case of FIG. 1, as shown in FIG. 1, each of the cover side protruding portion 201a to the cover side protruding portion 201c moves in the e direction. That is, the cover 200 rotates in the e direction.

(Step 4)
In step 4, the side of the slider 310 on which the spring 400 is attached abuts against the slider stopper 324 provided in the storage portion 320, so that the slider 310 is stopped from moving. As a result, the cover-side protruding portion 201 a is stored in a predetermined position of the storage portion 320. When the slider 310 is in contact with the slider stop 324, the tensile force f still remains, so the slider 310 is fixedly stored in the storage portion 320. Further, the cover-side protruding portion 201a is also fixedly stored in the storage portion 320.

When removing the cover 200 from the luminaire main body 100, the operations in steps 1 to 4 in FIG. 9 may be reversed. That is, when the cover 200 is housed in the housing portion 320 with the cover-side protruding portion 201a and the like being housed, the slider 310 is moved out of the housing portion by adding points in the direction opposite to the e direction. That is, Step 4 → Step 3 → Step 2 → Step 1 in FIG.
The cover 200 can be removed. Thus, the cover 200 can be removed from the luminaire main body 100 without requiring a special part for removing the release lever or the like.

FIG. 10 is a diagram illustrating a case where the storage unit 320 includes a storage-side guide unit 330. The storage-side guide portion 330 guides the cover-side protruding portion 201 a from the vicinity of the slider-side receiving portion 311 to the slider-side receiving portion 311 when the cover 200 is attached to the luminaire main body 100. That is, when the cover 200 is attached, the cover-side protruding portion 201a is positioned along the curve of the storage-side guide portion 330 by positioning the cover-side protruding portion 201a at any position within the range of the length L. The position can be easily moved to the slider-side receiving portion 311 in the order of (a) → (b) → (c). In FIG. 10, the storage-side guide portion 330 has a convex curve on the ceiling side, but in FIG. 10, the storage-side guide portion 330 may be a straight line that rises to the left toward the slider-side receiving portion 311. Further, in FIG. 10, the depth of the curved portion (or straight line that rises to the left) is not expressed, but the depth may be a plate shape or a plane. What is necessary is just to be able to guide the cover side protruding portion 201a.

  The cover mounting device of the present embodiment includes a slider and a storage portion, and when the slider side receiving portion receives the cover side protruding portion, the engagement with the storage side engaging portion by the slider side engaging portion is released, As the engagement is released, the cover-side protruding portion is moved to the inside of the storage portion while the slider-side contact portion is in contact with the cover-side protruding portion by the tensile force of the spring. Therefore, the lock is released by simply pressing the cover against the slider-side receiving portion of the slider, and the cover can be easily attached to the luminaire body.

  In the cover mounting device according to the present embodiment, since the storage portion is integrally formed as a part of the lighting fixture main body, it is possible to save the trouble of attaching the storage portion to the lighting fixture main body.

  Since the cover mounting device of the present embodiment includes the storage side guide portion, the mounting operator can easily move the cover side protruding portion to the position of the slider side receiving portion when mounting the cover. .

  Since the lighting fixture of the present embodiment includes the cover mounting device 300a and the like, the cover can be easily attached to the lighting fixture body with a simple structure.
