Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting fixture having a structure in which a fixture body including a lamp such as a fluorescent lamp is covered with a cover formed by connecting a plurality of transparent panels. Panel connection structure.

[0002]

2. Description of the Related Art A conventional example of a lighting fixture having such a structure (Japanese Patent Laid-Open No. 2000-276915) is shown in FIGS. FIG. 9 is an external view of the lighting fixture, and FIG. 10 is a sectional view.

In the structure of this conventional example, a fixture main body 51 including a lamp is covered with a cover composed of a frame 52 and three translucent panels 53. Each translucent panel 53 is made of resin or glass, and is fixed so that its end (side) is sandwiched between the frame 52 and the pressing metal fitting 54.

That is, with the end of the translucent panel 53 in contact with the inside of the frame 52, the pressing metal fitting 54 is applied to the end of the translucent panel 53, and the pressing metal fitting is pierced by the screw 55 passing through the pressing metal fitting 54. Tighten 54 against frame 52. A receiving portion 52 a for receiving the screw 55 and screwing the screw 55 is formed at a corresponding portion of the frame 52. By doing so, the end portions (sides) of two adjacent translucent panels 53 are simultaneously fixed and connected.

[0005]

However, in the cover structure (transparent panel connection structure) as described above, it is necessary to tighten each screw with a screwdriver, and the cover can be tightened from the inside. Therefore, the workability is poor and the assembly is troublesome. In particular,
When the size of the luminaire (that is, the size of the cover) becomes small, the workability of assembling suddenly deteriorates.

Further, the workability (maintenance workability) when the translucent panel is replaced due to damage or stain of the translucent panel is not good. It was necessary to remove the entire cover and then remove the corresponding single translucent panel. On this occasion,
Adjacent translucent panels that were not to be replaced sometimes came off.

The present invention has been made in view of the conventional problems as described above, and provides a lighting device having a structure in which the transparent panel constituting the cover can be easily attached (connected) or removed (disassembled). The purpose is to

[0008]

A lighting fixture according to the present invention is a lighting fixture having a structure in which a fixture main body including a lamp is covered with a cover composed of a frame and a plurality of translucent panels. An engaging receiving portion for receiving a fixing member for fixing an end portion of the translucent panel is formed in the fixing member and the engaging member with the end portion of the translucent panel abutting the inside of the frame. The fixing member is inserted into the engagement receiving portion by elastic deformation of at least one of the receiving portions, and as a result, the end portion of the translucent panel is fixed to the inside of the frame by the fixing member. And

According to this structure, since the end of the translucent panel is fixed to the frame by the work of inserting the fixing member into the engagement receiving portion formed inside the frame, the conventional screw is used. The workability is better than when it is fixed.

By fixing the outer connecting member to the inner connecting member in a state where the inner connecting member is in contact with the end of the inner connecting member, the two adjacent sheets are connected between the inner connecting member and the outer connecting member. It is characterized in that the end portions of the two adjacent light transmitting panels are fixed to each other so as to sandwich the end portions of the light transmitting panel.

With such a structure, the work of connecting the light-transmitting panel (the work of assembling the cover) can be performed from the outside of the cover, not from the inside, so that the workability is improved.

[0014] In a preferred embodiment, the outer connecting member is screwed to a holding member for holding the end of the translucent panel from the outside and an engaging portion provided on the inner connecting member penetrating the holding member. By rotating the screw from the outside, the end portion of the translucent panel is sandwiched between the inner connecting member and the pressing fitting of the outer connecting member.

In another embodiment, the outer connecting member is
The pressing member is configured to press the end portion of the translucent panel from the outside, and the latch member that penetrates the pressing member and is elastically engaged with an engaging portion provided on the inner connecting member.

[0016] In still another embodiment, the outer connecting member elastically engages a holding portion that holds the end of the translucent panel from the outside and an engaging portion provided on the inner connecting member. The joint part is integrally formed.

Further, in each embodiment, preferably, a decorative member for covering the outer connecting member and the end portion of the light transmitting panel is further provided.
