Further, as shown in FIGS. 4 to 6, the stopper 8 is provided on the light control body 5. Specifically, the first frame member 11b included in the light control body 5 located on the side of the insertion / removal hinge 6 is provided.
Is screwed to one end in the longitudinal direction. The one end portion in the longitudinal direction has the first hinge element 21 in a state where the light control body 5 is opened.
Is an end portion located on the front side in the moving direction of the light control body 5 when the light control body 5 is moved in a direction in which the second hinge element 22 is relatively removed. The stopper 8 is formed by bending a metal having a relatively high rigidity into, for example, an L shape, and prevents the movement of the opened light control body 5 in the removal direction.
It is used to prevent the adjacent member, which is continuously positioned in the removal direction, from hitting another lighting fixture A or dummy box C.

When the adjacent member is another lighting device A, the first frame member 11b on the side of the extraction hinge 6 of the light control body 5 which is maintained in the closed state of the lighting device A is used as a stopper receiver. , The end surface 11be of the frame member 11b (see FIG.
The stopper 8 is brought into contact with (see).

As shown in FIG. 11, the dummy box C
Is provided with a fixing portion E fixed to the ceiling B, a cover F as a detachable component detachably attached to the fixing portion E, a hinge mechanism G, and a latch mechanism H. The fixing portion E has the same configuration as the luminaire main body 1 of the luminaire A, and the cover F has the same configuration as that in which the first frame members 11a and 11b of the luminaire A and the globe 10 are integrally molded. The hinge mechanism G has a pivot that can be attached and detached with the cover F open, and can be disassembled by removing this pivot, so that the cover F can be detached from the fixed portion E. The latch mechanism H has the same structure as the latch mechanism 7 of the lighting fixture A.

When the dummy box C is used as the adjoining member, the cover F, which is formed to have a cross section substantially the same as the cross section in the direction orthogonal to the longitudinal direction of the light control body 5, serves as a stopper receiver. It is used and the stopper 8 is brought into contact with the end surface thereof.

In the luminaire A having the above structure, the light control unit 5
In order to open the light control body 5 when wiping the door, the operation piece 36b of the latch 32 is pushed in, and the latch engagement portion 31
Then, the engaging / disengaging piece 36a of the latch metal fitting 36 may be removed, and the light control body 5 may be rotated downward as shown in FIG. In such an open state, the inner surface and the outer surface of the globe 10 of the light control body 5 are wiped and cleaned.

In this cleaning, the light control body 5 is disassembled in the direction in which the pull-out hinge 6 supporting the light control body 5 on the instrument body 12 is disassembled, that is, the cylindrical portion 2 of the second hinge element 22 on the light control body 5 side.
9 may be dragged in a direction in which it is pulled out from the pin 24 of the first hinge element 21 on the instrument body 1 side.

Assuming that the movement of the light control body 5 in the removal direction is in the direction of arrow I in FIGS. 1, 4 and 5, respectively, the adjacent members arranged adjacent to this movement direction will be described. On the end surface, that is, on the end surface (indicated by reference numeral 11be in FIG. 5) of the first frame member 11b of the light control body 5 provided in another adjacent lighting fixture A of the same type in this example, the light control body 5 opened. The stopper 8, which is fixed to, immediately comes into contact with the movement of the light control body 5 in the I direction. When the adjacent member arranged adjacent to the I direction is the dummy box C, a stopper 8 fixed to the opened light control body 5 is provided on the end face of the cover in the I direction. Immediately hit as the light control body 5 moves.

As the light control body 5 opened with respect to the instrument body 1 is wiped and cleaned, the light control body 5 is moved by the arrow I.
Even when it is dragged in the direction, its movement is immediately hindered and the pin 24 of the first hinge element 21 on the instrument body side is
It is possible to prevent the second hinge element 22 from being inadvertently removed and removed from disconnecting the two hinge elements 21 and 22 of the insertion / removal hinge 6.

Therefore, the light control body 5 is prevented from being accidentally detached and damaged during the cleaning, and the work can be performed without worrying about the detachment of the light control body 5. Can be done easily.

In the state where the light control body 5 is opened as described above,
The male base 23 of the first hinge element 21 and the female base 28 of the second hinge element 22 are separated from each other. Therefore, the hook portion 30 of the second hinge element 22 does not face the receiving portion 25 of the first hinge element 21.

When it is necessary not only to open the light control body 5 but also to remove it from the main body 1 of the fixture, first, the stopper receiver (cover F of the dummy box C) of the lighting fixture A to be removed is controlled. The cover F of the dummy box C located on the I direction side is removed so as not to face the optical body 5. Next, the light control body 5 of the luminaire A to be removed may be opened by the procedure described above, and then the light control body 5 may be moved in the I direction. In this case, the stopper 8 does not hit the fixed portion E of the dummy box C. Therefore, I
Along with the movement of the light control body 5 in the direction, that is, the movement in the direction in which the first and second hinge elements 21 and 22 are separated, from the pin 24 of the first hinge element 21 to the cylindrical portion of the second hinge element 22. 29
Can be removed, and the light control body 5 can be removed.

Due to the removal of the light control body 5, the light control body of another luminaire A adjacent to the luminaire A from which the light control body 5 is removed on the opposite side to the direction I is controlled. This means that the stopper receiver that obstructs the removal of No. 5 has been removed. Therefore, after this, the light control body 5 of the other luminaire A is
By opening the light control body 5 and moving the light control body 5 in the I direction, the light control body 5 of the other lighting equipment A can be controlled without hitting the equipment main body 1 of the previous lighting equipment A from which the light control body 5 has already been removed. The light body 5 can be removed. By repeating such work, it is possible to remove any of the light control bodies 5 of the lighting equipment A mounted on the vehicle.

Contrary to the above removal procedure, in order to attach the removed light control body 5 to the instrument body 1, first, the second hinge element 22 fixed to the frame body 9 of the light control body 5 is attached. Is positioned on the first hinge element 21 fixed to the instrument body 1, and the light control body 5 is moved so that the hinge elements 21 and 22 come close to each other. Thereby, the pin 24 of the first hinge element 21
The cylindrical portion 29 of the second hinge element 22 is fitted to the above, the withdrawal-and-insert hinge 6 is assembled, and the frame body 5 is supported with respect to the instrument body 1 in an open state.

Next, the side of the light control body 5 to which the latch 32 is attached is pushed up toward the ceiling, and the light control body 5 is rotated by using the insertion / removal hinge 6 as a fulcrum. Place it in the closed position. Due to the rotation of the light control body 5 to the closed position, as shown in FIG. 7, the second hinge element 22 is caught by the receiving portion 25 of the first hinge element 21 opposite to the protruding direction of the pin 24. The parts 30 closely face each other with a minute gap g.

Therefore, when the frame body 5 attempts to move in the direction in which the pin 24 and the cylindrical portion 29 are disengaged from each other due to the vibration accompanying the traveling of the vehicle, the catching portion 30 and the receiving portion 25 are immediately caught. , The movement of the light control body 5 is further restricted. That is, it is possible to prevent the light control body 5 from rattling in the longitudinal direction with respect to the instrument body 1 and generating noise. As a result, the risk that the latch mechanism 7 is disengaged accidentally can be reduced.

Moreover, since the receiving portion 25 and the catching portion 30 face each other at a close distance until the above-mentioned regulation is performed, the light control body 5 is moved from the open position to the closed position with respect to the instrument body 1. When rotating, the catching portion 30 of the second hinge element 22 rarely interferes with the receiving portion 25 of the first hinge element 21. Therefore, the light control body 5 can be rotated with respect to the instrument body 1 to a properly closed position. Thereby,

Therefore, in the second embodiment, when the light control body 5 is opened with respect to the instrument body 1, the light control body 5 hits the regulating portion 52 of the instrument body 1 as shown in FIG. The opening angle Θ of 5 is regulated.

Then, when the light control body 5 thus opened is moved in the direction for releasing the connection of the first and second hinge elements 21 and 22 with the wiping and cleaning of the globe 10 and the like, the light control body 5 is controlled. The end in the longitudinal direction of the insect-proof packing 48 located near the extraction / insertion hinge 6 of the optical body 5 immediately contacts the end of the adjacent member arranged adjacent to the moving direction. Therefore, it is possible to prevent the second hinge element 22 on the light control body side from being accidentally removed from the pin 24 of the first hinge element 21 on the instrument body side.

Therefore, similarly to the first embodiment, the light control body 5 is prevented from being accidentally dropped and damaged during the cleaning, and the work is performed without worrying about the fall of the light control body 5. Therefore, cleaning can be easily performed. Further, the light control body 5 can be detached from the instrument body 1 if necessary.

Moreover, in the second embodiment, since the insect-proof packing 48 is applied to the adjacent member to prevent the opened light control body 5 from moving in the removal direction, the end of the adjacent member is not damaged.

Further, as described above, the opening angle Θ of the light control body 5
Since the restricting portion 52 for restricting the restricting portion 52 is integrally provided on the mounting bracket 26 that is attached to the instrument body 1 and to which the first hinge element 21 is fixed, the number of parts is increased without requiring a dedicated part for the restricting portion 52. Do not invite Moreover, this regulation unit 5
The strength of No. 2 is not restricted by the plate thickness of the instrument main body 1, but depends on the plate thickness of the mounting bracket 26 thicker than the instrument main body 1, so that the opening angle of the light control body 5 can be reliably regulated. it can.
