Description

[Detailed description of the device]

[0001]

[Detailed industrial description]

 The present invention relates to a lighting fixture, and more particularly to a lighting fixture assembled in a rectangular shape.

[0002]

[Prior Art]

 In order to construct the ceiling of a building, it is practiced to attach the ceiling surface to the ceiling of the building using hanging bolts. The structure for this is to fix the suspension bolts to the ceiling, attach a plurality of field edge supports at appropriate intervals to the suspension bolts, and attach the field edge materials so as to straddle adjacent field edge supports. Fix it. Then, the ceiling surface is attached using this wild edge material. For the ceiling surface, attach the board that is the base material to the edge material and attach the ceiling finishing material to this board.

On the ceiling surface configured in this way, there are cases where a lighting fixture is constructed by assembling four lighting fixtures in a rectangular shape. For this reason, we have created a space on the ceiling to accommodate this lighting fixture, and install the lighting fixture in that space.

In that case, a further ceiling surface (which will be referred to as the following will be referred to as “filling space”) in the central space of the lighting device thus installed (the space surrounded by four lighting devices alone) It is necessary to install the central ceiling surface.).

The central ceiling surface is separated from the ceiling surface around the lighting fixture. Therefore, in the past, special suspension bolts for hanging the central ceiling surface, field edge support materials, and field edge materials were used, and these were used to install the central ceiling surface. Therefore, the structure for mounting the central ceiling is complicated. In addition, in order to separately attach the central ceiling surface and the surrounding ceiling surfaces in this way, it is necessary to adjust the height of both ceiling surfaces.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to facilitate mounting of a central ceiling surface when mounting a rectangular lighting fixture on the ceiling surface.

[0007]

[Means for Solving the Problems]

 The present invention is a luminaire in which four luminaires are connected to each other to be assembled in a rectangular shape, and a plurality of luminaires are hung from the ceiling part by hanging bolts. It is characterized by arranging the bars of each of the above, and attaching each bar to its facing luminaire unit, and installing a central ceiling surface that fills the central space enclosed by the luminaire unit assembled in a rectangular shape to this bar. And

[0008]

[Action]

 Unlike the conventional configuration, the bar that attaches the central ceiling surface is fixed to the lighting fixture alone. Therefore, it is not necessary to attach this bar to the ceiling with hanging bolts. This eliminates the need to prepare special suspension bolts, field edge receiving materials, and field edge materials for attaching the central ceiling surface in order to attach the central ceiling surface.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. 1 to 4 are lighting fixtures alone, and a lighting fixture is constructed by assembling these into a rectangular shape. Each of the lighting fixtures has a U-shaped cross section, and a pair of sockets facing each other is attached to each interior of the lighting fixtures, and the sockets support the fluorescent lamp. In the figure, the socket and the fluorescent lamp are omitted. These configurations are not particularly different from the conventional ones.

In the illustrated embodiment, the luminaires 1 and 2 are configured to be longer than the luminaires 3 and 4, and the end faces of the luminaires 3 and 4 are provided on the respective end side surfaces of the luminaires 1 and 2. It is assembled into a rectangular shape by butting and connecting. The lighting fixtures 1 and 2 are supported on the ceiling part by hanging bolts 5 hanging from the ceiling part (not shown). This is convenient because it is not necessary to hang the lighting fixtures 3 and 4 on the ceiling portion with the hanging bolts.

Reference numeral 6 denotes a surrounding ceiling surface which is attached to the ceiling portion by the hanging bolt, the field edge support material, and the field edge material as described at the beginning, and according to the present invention in the rectangular space formed here. Install lighting equipment. Then, the central ceiling surface 7 is installed in the central space of the installed lighting equipment. To install the central ceiling surface 7, a plurality of bars 8 supported by the lighting equipments 1 and 2 are used. .

The bar 8 is attached to the lighting fixtures 1 and 2 as follows. That is, the connecting fitting 9 is fixed to the lighting fixtures 1 and 2 with screws 10. The lower end of the connecting fitting 9 is bent, and a support bar 12 having a U-shaped cross section is fixed to the bent portion 11 with a screw 13. The gutter-shaped bar 8 is attached to the support bar 12. The clip 15 is used for this attachment.

That is, the clip 15 is fixed to the support bar 12 with screws or the like. The claw portions 16 formed on both sides of the lower end of the clip 15 are engaged with the folded-back portions 17 formed by bending the upper end of the side wall of the bar 8 (see FIG. 5). As a result, the bar 8 is fixed to the lighting fixtures 1 and 2 via the connecting fitting 9 and the support bar 12.

The central ceiling surface 7 is attached to the bar 8. The central ceiling surface 7 is composed of a board 18 as a base material and a ceiling finishing material 19 like the surrounding ceiling surface 6. The board 18 is fixed to the bar 8 with screws 20. Then, the ceiling finishing material 20 is attached to the board 19 by a nail, a tacker or the like, or by an adhesive. In this way, when the central ceiling surface 7 is attached to the bar 8, the outer periphery thereof is placed on the bent edge 21 formed by bending the lower end of the side wall of each lighting fixture.

With this structure, the bar 8 used to attach the central ceiling surface 7 is attached to the lighting fixtures 1 and 2 independently of the conventional lighting fixtures. There will be no need for separate suspension bolts or the like. Therefore, the attachment of the bar 8 and, therefore, the attachment structure of the central ceiling surface 7 becomes extremely simple.

Since the bar 8 is attached to the lighting fixtures 1 and 2, if members having fixed dimensions are used as members such as the connecting fitting 9, the support bar 12 and the clip 15, which are used for attachment, The height position of the bar 8 is always constant with respect to the lighting fixtures 1 and 2. Therefore, since the height position of the central ceiling surface 7 is always constant, there is no need to adjust the height position, which is convenient.
