In order to prevent the handle 7 from swinging from side to side, it is preferable that the handle 7 has a larger surface than its opening.

In such a configuration, the glove 3 is attached to the upper lid 2 by locking the collar portion 4 onto the locking piece 12 and the engaging piece 8.

This attachment is performed by first hooking one end of the flange 4 onto the locking piece 12, and pushing the glove 3 upward while bringing the other end into contact with the inclined surface of the hook-shaped tip 9 of the engaging piece 8. .

That is, when the glove 3 is pushed in while the flange 4 is in contact with the hook-shaped tip 9, the retaining piece 8 moves to the outside of the side plate and the bottom corner C of the handle 7 is moved as shown in FIG. The flange part 4 is attached to the retaining piece 8 because it becomes unstable and is lifted upward.
Can be inserted above.

Furthermore, the upper part of the glove 3 engages with the retaining piece 8 which has been returned to its original position by the action of the coil spring 11.

In this way, the glove 3 is attached to the locking piece 12 and the engaging piece 8.
It is attached to the upper lid 2 by being locked to.

In this mounting state, the weight of the glove 3 is applied to the retaining piece 8, but even if the handle 7 tries to rotate about the inner corner A of the engaging piece through hole 6, the tip B of the engaging piece rotation regulating piece 5
It is prevented from rotating counterclockwise by contacting with.

Therefore, the glove 3 can be safely attached to the top lid 2 without falling off downward.

Furthermore, the retaining piece 8 presses the upper part of the glove 3 due to the elastic force of the coil spring 11, and holds the glove 3 more firmly.

This type of glove attachment is sometimes done in order to soften the impact caused by the collision between the shoulder of the upper part of the glove and the lower part of the side plate.
A cushioning material such as rubber may be attached to the lower part of the side plate.

Further, by pulling the handle 7 outward, the engagement between the engagement piece 8 and the upper part of the glove 3 is released, and the glove 3 can be easily removed.

In this embodiment, the locking piece 12 fixed to the upper lid 2 facing the glove engaging device 1 is used, but the two glove engaging devices may be arranged substantially facing each other.

In this way, putting on and taking off the glove becomes more of a task.

In the engagement device according to this invention, as shown in FIG. 4, an engagement piece rotation regulating piece may be formed separately from the main body of the lighting fixture.

The component 20 shown in FIG. 2A is formed by cutting and raising an engagement piece rotation regulating piece 21, and an engagement piece introduction hole 22 is bored below the engagement piece rotation regulating piece 21.

This component 20 is fixed in a state in which the engagement piece rotation regulating piece 21 is penetrated into the hole 23 of the side plate of the upper lid 25 from the inside.
