DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting apparatus which is mounted on a ceiling and has a glass glove mounted on a lower surface thereof.

[0002]

2. Description of the Related Art FIGS. 9 and 10 show a conventional luminaire having a glove. The luminaire includes a luminaire main body 1, a globe 2, and a glove support which is a support for the globe 2. FIG. And a member 3.

[0003] The appliance body 1 has a substantially disk-shaped body bottom portion 1a disposed to face the ceiling surface, and a flange portion 1b erected downward at the end periphery thereof. The main body bottom 1a is provided with an elongated hole 1c for slidably locking the glove support member 3 toward the center of the instrument main body 1.

The globe 2 is formed of a translucent material, has a substantially hemispherical shape with one opening, and has a shoulder 2a formed near the opening end in a direction to narrow the opening. The opening side of the shoulder portion 2a is a cylindrical portion 2b having substantially the same height as the flange portion 1b, and is disposed so that the outer surface of the shoulder portion 2a contacts the tip of the flange portion 1b of the instrument body 1. And a space for accommodating the lamp 5 and the like is formed between them.

[0005] A glove support fitting 3 serving as a support portion of the glove 2 has a mounting piece 3 attached to the bottom 1a of the main body 1 at one end.
a, a hanging part 3b hung from the mounting piece 3a, and a locking piece 3c which is bent outward from the lower end of the hanging part 3b to the outside of the instrument body 1 and on which the shoulder 2a of the glove 2 is placed. The tip of the locking piece 3c is bent obliquely inward toward the inside of the device to form a guide piece 3d, and the glove support 3 has elasticity. The glove support 3 is provided in a pair in the 180-degree direction of the instrument body 1, and its mounting piece 3 a is slidably locked in a slot 1 c provided in the bottom 1 a of the instrument body 1. And slides vertically with respect to the flange portion 1b so as to be able to advance and retreat.

In the lighting fixture thus constructed, when the globe 2 is mounted, the pair of glove support brackets 3 is slid toward the center of the fixture main body 1 and the glove 2 is pushed up from below. When the cylindrical portion 2b of the glove 2 hits the guide piece 3d, the glove 2 is pushed up while the glove support 3 is elastically deformed, and the shoulder 2a passes through the locking piece 3c, the glove support 3 becomes The original shape is obtained, and the shoulder 2a is on the upper side of the locking piece 3c. Thereafter, the glove support 3 is slid in the outer direction of the instrument body 1, and the glove support 3 is fixed by screws or the like. , And the glove 2 was worn.

Therefore, when the glove 2 is loosened due to vibration or the like or is forgotten to be tightened and the glove 2 tries to drop, the locking piece 3c of the glove support 3
However, it hits the shoulder 2a of the glove 2 to prevent the glove 2 from falling.

When the globe 2 is a glass glove, since the glass glove is a component that is easily damaged, a hole is provided in the glass glove to support the weight thereof, including the case where the glove support 3 is provided. In general, the glove 2 is supported by providing the glove support 3 as described above, or a screw is provided on each of the glass glove and the instrument body, and these are screwed together.

[0009]

However, in the conventional luminaire constructed as described above, the glove support 3 serving as the support for the globe 2 also serves as the fall prevention part. It is necessary to design the glove support 3 in consideration of attachment and detachment, and its fall prevention function cannot be said to be sufficient. If the screw of the glove support 3 is loosened, or the glove support 3 is forgotten to be closed, the glove support 3 is not used. When sliding toward the center of the instrument body 1 due to vibration or the like, there is a problem that the globe 2 may fall. In particular, when the globe 2 is a heavy object such as a glass glove, this problem is remarkable because the glove support 3 is easily deformed.

Further, since the glove support 3 serving as the support portion of the glove 2 also serves as the fall prevention portion, it is difficult for the user to recognize the state in which the glove support 3 is loose. Therefore, there is a problem that the device may be used without being repaired.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to make it easy to confirm even if a support portion of a glass glove comes off, and to prevent the glass glove from falling. It is an object of the present invention to provide a lighting device which is surely prevented.

[0012]
