At
Between adjacent receiving metal fittings, a receiving tool having a guide portion for guiding a glove to a normal position with respect to the device main body is provided, and the receiving metal fittings and the receiving tools are arranged on the top plate at a substantially equal pitch,
When the glove is attached to the device main body, the overhang is provided at the place corresponding to the receiving fitting and the receiving implement, and the overhang is supported by the receiving implement.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram showing a lighting device according to an embodiment of the present invention, where (a) is a cross-sectional view of a main part, (b) is a bottom view of a main part, and FIG.
FIG. 1 is a schematic perspective view showing a receiver 11 according to the present embodiment. The lighting fixture includes a fixture body 1 and a fixture body 1
And a glove 2 which is attached by being rotated.

The globe 2 surrounds the lamp 6 and has a rising portion 8 facing upward when attached to the periphery of the opening, a flat portion 2a connected to the rising portion, and a projecting portion projecting toward the center of the opening at the opening end. 3, the diameter of the rising portion 8 is configured to be smaller than the diameter of a later-described rising portion 7 of the instrument body 1, and the overhanging portion 3 is provided with an auxiliary stopper 10.

The lighting device 5 and the lamp 6 are attached to the center of the substantially disk-shaped top plate 1a, and the fixture body 1 is provided with a rising portion 7 which faces downward in a mounted state on a peripheral edge portion. The receiving metal fitting 4 is provided on the top plate 1a close to.

As shown in FIG. 6, the receiving member 4 is substantially L-shaped, and has a substantially horizontal receiving portion 4a at the lower end, and an obliquely downward direction from the lower end of the receiving portion 4a along the circumferential direction of the instrument body. An auxiliary stopper 10 provided on the overhang portion 3 is guided by the guide portion 4b by pushing up and rotating the opening of the glove 2 together with the device main body 1 so as to be guided by the guide portion 4b. To the receiving part 4a.
a and is mounted on the instrument body 1.

Also, the top plate 1a close to the rising portion 7
Are provided with the same number of receiving members 11 as the receiving metal members 4, and the receiving metal members 4 and the receiving members 11 are alternately arranged on the top plate 1a at an equal pitch.

The receiving device 11 is for guiding the glove 2 to a normal position with respect to the device main body 1. The receiving device 11 has a substantially U-shaped holding portion 11a and a guide portion provided on the bottom surface of the lower end of the holding portion 11a. 11b. When the glove 2 is rotated at a position other than the normal position with respect to the device main body 1, the auxiliary stopper 10 hits the guide portion 11b and cannot rotate the glove 2. When the glove 2 is rotated at the normal position, the auxiliary stopper is rotated. 10 enters the holding unit 11a and is held by the holding unit 11a. Here, the protruding portion 3 of the glove 2 is provided at a position corresponding to the receiving fitting 4 and the receiving tool 11 when the glove 2 is attached to the instrument body 1.

Further, the tip of the rising portion 7 is equally provided on the flat portion 2a of the globe 2, thereby ensuring insect repellency.

Therefore, in the present embodiment, when heat is applied to the globe 2, the portion where the glow 2 is most likely to hang down (as a conventional example, between the metal fittings 4 and 9 of the lighting fixture shown in FIGS. 4 and 5). A receiving member 11 is provided in the middle)
Since the auxiliary stopper 10 provided on the glove 2 is held, it is possible to prevent the glove 2 from sagging when heat is applied, and to prevent a gap between the glove 2 and the instrument body 1 from being generated. Insect repellency can be ensured.

Further, since the receiving tool 11 also serves as a guide for guiding the glove 2 to a normal position with respect to the instrument body 1, the glove 2 can be easily attached to the instrument body 1.

Further, since the number of places for supporting the auxiliary stopper 10 is increased (the place where the receiving fitting 4 and the receiving tool 11 are provided), the rotation angle when the glove 2 is attached to the instrument body 1 is reduced, and the attachment is easier. Become.

In the present embodiment, the auxiliary stopper 10 is supported by being inserted into the receiving portion 4a of the metal fitting 4 and the holding portion 11a of the receiving member 11, but is not limited to this. Instead, for example, as shown in FIG. 3, the overhanging portion 3 may directly enter and support the receiving portion 4 a of the receiving fitting 4 and the holding portion 11 a of the receiving tool 11.

[0022]

According to the first aspect of the present invention, since the receiving member is provided between the adjacent receiving members, when heat is applied to the glove, the portion where the glow is most likely to hang is supported by the receiving member, and the heat is released. It is possible to prevent the glove from hanging when it is added, and since the receiving device has a guide portion for guiding the glove to a normal position with respect to the instrument body, the glove can be attached to the instrument body. Easier and also
Since the overhang is supported by the receiving device and the receiving bracket,
The number of places to be supported increased, the rotation angle when attaching the glove to the fixture body was reduced, the attachment became easier, and it was possible to provide a lighting fixture that could ensure insect repellency even when heat was applied. .
