[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air blowing structure, for example, an air blowing structure which is attached to a ceiling of a room and blows air into the room to adjust the air environment in the room.

[0002]

2. Description of the Related Art Such an air blowing structure is widely used especially in a room of a building such as an office for controlling the air condition and room temperature of the room.

As such an air blowing structure, a structure as shown in FIG. 12 is generally used. That is, in FIG. 12, the structure for blowing air is a surface plate composed of a metal rail a and a glass wool plate c1, a back plate (not shown) arranged in parallel with the surface plate, and the surface plate. And an air inlet d provided in at least one of the back plate, two side plates b that close the side surfaces of the gap between the front plate and the back plate, and a top plate that closes the upper surface of the gap between the front plate and the back plate. c2 and an adjusting plate g which is located inside an air blowing gap formed by the lower surface of the gap between the front plate and the back plate, is rotatably supported by the side plate b by a screw f, and controls the air blowing direction. It consists of and. This air blowing structure is constructed by using T-shaped steel or the like on the ceiling of a building or the like, with the lower surface (air blowing gap) facing the room, and the hot or cold air introduced from the air inlet d. It is applied to indoor air conditions and room temperature control by blowing air from the air blowing gap into the room. The metal rail a is fixed by two screws driven from the side plate b.

[0004]

However, in such an air blowing structure, since the height of the metal rail is small, as shown in FIG. 12, two screws are driven into the narrow and short portion. There was a problem that it was difficult.

On the other hand, if the metal rail is fixed with a single screw, the metal rail can rotate around the screw as a central axis, and the rail cannot be securely fixed.

The present invention has been made on the basis of such a technical background, and it is possible to securely fix the metal rail by using one screw, and therefore, it is possible to easily and surely assemble the rail. It is an object of the present invention to provide an air blowing structure that can be used.

[0007]

That is, according to the present invention, metal rails provided on each of the front surface and the back surface, an air inlet provided on at least one of the front surface and the back surface, and the side of the front and back rails are provided. The main part is composed of two side plates that are screwed to the end faces and close the side surfaces of the gap between the front and back rails, and the lower surface of the gap between the front and back rails constitutes the air blowing gap. In the air blowing structure, the side plate has at least two cuts at each side end, and a segment between the cuts is bent in the gap direction and is in contact with the inside of the rail. It is characterized by that.

[0008]

In the air blowing structure according to the present invention, at least two notches are provided at each of the side end portions of the side plate, and the section between the notches is bent in the gap direction so as to be inside the metal rail. Since they are in contact with each other, even when the metal rail is fixed to the side surface plate with a single screw, the section in contact with the metal rail prevents rotation of the metal rail.
