Description

[Detailed Description of the Invention] This invention relates to a lighting fixture equipped with an air conditioning duct.

2. Description of the Related Art Lighting fixtures, particularly recessed lighting fixtures, are known to have an air conditioning duct installed therein. FIG. 1 shows the structure of the apparatus. Reference numeral 1 denotes a main body of the apparatus, which has a box-like structure with an open bottom, and an edge 2 formed by bending the periphery of the opening. 3 is a fluorescent lamp, and 4 is a translucent panel. Air conditioning ducts 5 are installed at opposing edges 2 of the opening surface of the appliance body 1. That is, the duct 5 has an open bottom surface, and this open surface is connected to the ventilation hole 6 formed in the edge 2.
It is placed opposite to. Both ducts 5 are also connected to both ends of another duct 7. Hot (or cold) air enters the duct 7 from the duct 8 from its generation source, and is then radiated to the outside through the ventilation openings 6 from both ducts 5. In addition, the air inside the room is radiated to the outside from the periphery of the panel 4 through the appliance body 1 and the turnbox 8'. 9 is the ceiling surface. The appliance main body 1 is adapted to be appropriately fixed to the ceiling surface.

By the way, since the duct 5 is manufactured separately from the instrument body 1, it is necessary to fix it to the instrument body 1. Conventionally, L is attached to the side wall 1A of the instrument body 1.
One end of the letter-shaped metal fitting was fixed, and the duct 5 was inserted between the other end of the metal fitting and the other side wall 1B of the appliance body 1 so as to fit therein. Although this is effective for positioning the duct 5 with respect to the instrument body 1, it requires a special metal fitting for fixing.

The purpose of this invention is to simplify the structure by using metal fittings that connect the abutting portions of the edges of the device body to secure the duct.

In other words, in order to provide the edge 2 on the instrument body 1, an extended portion of the side wall 1A is bent to form the edge 2A, and an edge 2B (in the illustrated example, the ventilation hole) is perpendicular to the edge 2A. 6) is manufactured separately from the instrument main body 1, and its end is used by butting it against the end of the edge 2A. 10
indicates the butt part. In this way, both edges 2A, 2
When B is used, a connecting fitting 11 is used to connect both edges 2A and 2B. Connecting fittings 11
are installed on both edge portions 2A, 2B across the butt portion 10 and fixed by spot welding or the like. In this invention, the connecting fitting 11 is intended to be used for fixing the duct 5. For this purpose, as shown in the figure, the connecting fitting 11 is integrally provided with an upright piece 12A, and is further provided with a bent upright piece 12B bent in an L shape relative to the upright piece 12A.

In reality, the device main body 1 is constructed by bending a metal plate into a U-shape, but since both ends remain open, an end plate (this becomes the side wall 1B) is used to close this off. .)is necessary. Therefore, the edge portion 2B and this end plate are usually constructed integrally.

As mentioned above, connect the connecting fitting 11 to both edges 2A, 2B.
After fixing across and connecting both edges 2A and 2B, the duct 5 is placed in a space surrounded by the upright piece 12A, the bent upright piece 12B, and the other side wall 1B of the instrument body 1. to fit. Although only one end of the duct 5 is shown in FIG. 2, the opposite end is similarly connected to the upright piece of the connecting fitting and the side wall 1.
Needless to say, it is fitted between B and B.

If the duct 5 is supported on the edge 2B in this way, the duct 5 will have an upright piece 12A, a bent upright piece 12B, and a side wall 1 on both sides.
Since it is supported by being sandwiched between B and B, it can be reliably installed at a predetermined position.

As detailed above, according to this invention, the metal fitting for fixing the air conditioning duct on the edge of the appliance body is made to use a part of the connecting metal fitting that connects the butt part of the edge. , it is no longer necessary to prepare special metal fittings for fixed installation of the duct as in the past, which reduces the number of parts used, and also eliminates the need to attach the metal fittings to the appliance body. play.
