BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device which is directly mounted on a mounting surface such as a ceiling or the like, and which has a main body directly fixed to the mounting surface and a glass detachably connected to the main body. The present invention relates to a lighting device including a shade portion made of a translucent member or a transparent member such as resin or resin.

[0002]

2. Description of the Related Art Conventionally, a V-shaped spring provided in a shade portion is inserted into a narrow guide of a main body portion, and the shade portion is connected to the main body portion by a retracting action due to expansion of the spring in the guide. There is a structure. There is also a structure in which the main body and the shade are fixed with screws.

[0003]

In the conventional structure as described above, at least two workers, a person who supports the shade portion and a person who inserts or screws the spring into the guide, are required for installation work or the like. From the point of view, there is a problem that labor costs increase.

[0004] In particular, in the recent situation of labor shortage,
Securing two persons for the installation work of the lighting equipment and the like has a problem that it is difficult to secure the personnel itself as well as a problem of labor cost.

Accordingly, the present invention has been made to provide a coupling structure in which a single operator can easily and reliably attach and detach a shade when attaching and detaching a lighting fixture.

[0006]

According to the present invention, there is provided a connecting structure for connecting a main body fixed to a mounting surface such as a ceiling and a shade portion detachably connected to the main body with the connecting surface. A fixed convex portion is formed on one of the main body portion and the shade portion, and an introducing portion for introducing the convex portion and a concave portion having a shape corresponding to the convex portion are formed on the other of the coupling surfaces. Means has been taken to urge the provided member toward the coupling surface by means of an elastic member.

[0007]

According to the present invention, the above means are taken, so that the shade portion is slid along the joint surface to form the convex portion formed on one of the main body portion and the shade portion of the joint surface on the other. When introduced from the introduction portion, the convex portion is introduced while deforming the elastic member, and is captured by the concave portion. This state is maintained by the elastic urging force of the elastic member.

When the shade portion is removed from the main body, the convex portion caught in the concave portion is detached from the introduction portion while deforming the elastic member by sliding in the opposite direction. The state is released.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. As shown in FIG. 1, 1 is a main body fixed to a mounting surface such as a ceiling, and 2 is a shade that can be detachably connected to the main body.

The main body 1 has a round fluorescent tube and a lighting mechanism therefor, and a coupling structure 3 for coupling the main body 1 and the shade 2 is formed on each coupling surface. .

As shown in FIGS. 1 and 2, the coupling structure 3 comprises a convex portion 4 attached to the shade portion 2 and a leaf spring member 5 fixed to the main body portion 1. In the spring member 5, a concave portion 52 having a shape corresponding to the introduction portion 51 and the convex portion 4 is formed. The leaf spring member 5 is provided so as to bias toward the mounting surface. The end of the leaf spring portion 5 is bent and inserted into a hole provided on the coupling surface, and is fixed with a screw to prevent displacement.

It is preferable to provide about three sets of the coupling structure 3 on the coupling surface.

In the above configuration, as shown in FIG.
When the position of the coupling structure 3 between the shade part 2 and the main body part 1 is roughly adjusted, and the shade part 2 is slid along the coupling surface, the convex part 4 pushes and spreads the introduction part 51 to the leaf spring member 5. It is introduced and is stabilized in a state of being fitted into the concave portion 52. This state is maintained by the elastic force of the leaf spring member 5.

When the shade 2 is detached from the main body 1 for removal from the ceiling or replacement of the fluorescent lamp, the shade 2 is slid in the direction opposite to the above along the connecting surface.
The convex portion 4 pushes and expands the leaf spring member 5 so that the concave portion 5
2, the main body 1 and the shade 2 are separated from each other through the introduction portion 51.

In this way, the shade portion 2 can be easily attached and detached.

If only the rough alignment is performed in this way, it is only necessary to turn the shade portion 2 while supporting it, so that only one worker is sufficient, so that the mounting and removing work can be performed efficiently. can get. In addition, the coupling structure can be configured by simply attaching simple hardware,
The rise in costs can be suppressed.

A leaf spring member may be provided on either the main body or the shade. Further, the elastic member is not limited to a leaf spring, and may be another elastic member. The connection may be performed by rotation or translation, and may be performed by fitting the concave portion and the convex portion. The shape of the concave portion may be a shape like [A] in FIG. 3 or a shape like [B].

In the case of a round-shaped lighting device, it is suitable to rotate and connect, and in the case of a square-shaped lighting device, it is suitable to translate and connect.

[0019]

According to the present invention, it is possible to attach and detach the main body by simply turning the shade while supporting it, so that only one worker is required, and there is an effect that the work of attaching and detaching can be efficiently performed by a small number of workers. . Further, since the coupling structure of the present invention can be constituted by simple members, it is possible to reduce the price of the product.
