Is described in Japanese Patent Application Publication No. In this air-conditioning grill, as shown in FIG. 7, a plurality of bendable wind direction deflecting plates 52 are disposed in a main body member 51 through which a wind W from the rear (from the left in FIG. 7) can pass. A shaft 53 at the front end of the wind direction deflection plate 52 is fixed to the main body member 51, and a shaft 54 at the rear end is connected by a connecting rod 55. An operation lever 57 is rotatably supported by a shaft 56 between the adjacent wind direction deflection plates 52 in the main body member 51, and a shaft 58 at the rear end of the operation lever 57 is connected to the connection rod 55.
It is connected to.

る。In this air-conditioning grill, the distance between the two shafts 56, 58 of the operation lever 57 is equal to the distance between the two shafts 53, 54 when the wind direction deflecting plate 52 is flattened.
It is set to be shorter than the distance between them. Then, as shown in FIG. 8, the wind direction deflecting plate 52 is rubber ",
It is formed of a soft material such as a hard resin in the shape of a thin plate, and has the same plate thickness t at any portion except front and rear ends.

風Ｗが通過する際に発生する騒音をある程度まで低減で
きる。Therefore, according to the air-conditioning grill of the conventional configuration, when the operation lever 57 is rotated, the connecting rod 55 moves with the rotation, and the distance between the front and rear shafts 53, 54 of the wind direction deflecting plate 52 decreases. It becomes shorter and the wind direction deflection plate 52 is curved. As described above, the wind W introduced into the main body member 51 blows out forward of the main body member 51 while changing the wind direction along the wind direction deflection plate 52. Therefore, in this air-conditioning grill, the noise generated when the wind W passes between the wind direction deflecting plates 52 can be reduced to some extent.

ないという問題があった。[Problems to be Solved by the Invention] However, in the prior art, as described above, the wind direction deflecting plate
Since the thickness t of the deflecting plate 52 is the same at any part of the deflecting plate 52, when the operation lever 57 is rotated to bend the deflecting plate 52, the central portion of the deflecting plate 52 has a large curvature. , And hardly bends at the front end portion fixed to the main body member 51. Therefore, the portion of the wind direction deflecting plate 52 from the middle to the front end side is not curved in a smooth arc shape, and the wind direction of the wind W passing between the adjacent wind direction deflecting plates 52 is changed to the curved concave surface of the wind direction deflecting plate 52. There was a problem that it could not be changed smoothly along.

用グリルを提供することにある。The present invention has been made in view of the circumstances described above, and its purpose is to be able to curve the front end side more smoothly in the middle of the wind direction deflection plate into a circular arc shape and to be introduced into the main body member. It is an object of the present invention to provide an air-conditioning grill that can blow air forward while smoothly changing the direction of wind along a curved concave surface of a wind direction deflection plate.

その要旨とするものである。Means for Solving the Problems In order to achieve the above object, the present invention provides a plurality of bendable wind direction deflecting plates in a main body member through which wind from the rear can pass, in either the left-right direction or the up-down direction. The front end of each wind direction deflection plate is supported by the main body member, and each rear end is connected by a connecting member movably provided in the front-rear and left-right directions. Along with the rear end portion connected by the connecting member among the front end portion and the rear end portion of each wind direction deflecting plate, the rear end portion can be moved within a certain range in the arrangement direction, and rearward at the center in the installation direction. Further, in an air conditioning grill configured to be movable forward on both sides in the arrangement direction, the thickness of the wind direction deflecting plate is set to be smaller toward the front side, and the front-rear length l of the wind direction deflecting plate is set to 10 mm ≦ l ≦ 60 mm, the wind deflecting plate rear end of the plate thickness t 1 of 1.5 mm ≦ t 1 ≦ 6 mm of the The ratio of the thickness t 1 of the plate thickness t 2 and the rear end portion of the front end portion of the counter-deflection plate t 2 / t 1
Are set to 0.3 ≦ t 2 / t 1 ≦ 0.6, respectively.

きを変えながら前方へ吹き出る。[Operation] When the connecting member is moved, the rear end of the wind direction deflecting plate connected to the connecting member also moves integrally. In the present invention, since the thickness of the wind direction deflecting plate is set to be smaller toward the front side, the rigidity of the wind direction deflecting plate itself is smaller toward the front side. Therefore, the wind direction deflecting plate is curved at substantially the same curvature from the middle to the front end side, and the wind introduced into the main body member blows forward while smoothly changing the wind direction along the wind direction deflecting plate. .

In the range of 5 mm ≦ t 1 ≦ 6 mm and 0.3 ≦ t 2 / t 1 ≦ 0.6, the wind direction deflecting plate is bent in a state approaching an arc without limit. Among these conditions, in particular, it is considered that the range of 0.3 ≦ t 2 / t 1 ≦ 0.6 contributes to the curved state. Outside this range, the portion from the middle to the front end side of the wind direction deflector does not curve with almost the same curvature, and therefore,
The wind introduced into the main body member cannot be smoothly turned along the wind direction deflection plate.

If it is larger, the resistance of the same portion when passing through the wind will increase. Further, if the front-rear length l of each wind direction deflecting plate is shorter than 10 mm, the degree of curvature of each wind direction deflecting plate is small, and the flow of wind cannot be changed smoothly. Same length around 60
If it is longer than mm, there is a problem in the strength of the wind direction deflecting plate (force for maintaining a curved state, etc.).

It is necessary to set 1.5 mm ≦ t 1 ≦ 6 mm and 0.3 ≦ t 2 / t 1 ≦ 0.6, respectively. When these conditions are satisfied, the portion of the wind direction deflecting plate 8 from the middle to the front end side is curved in a state approaching an arc without limit. Among the conditions, the ratio t 2 / t 1 with thickness t 1 of the plate thickness t 2 and the rear end portion of the front end portion of the wind direction deflection plates 8 is based on the analysis result by the finite element method, in particular, 0.3 It is considered that satisfying the condition of ≦ t 2 / t 1 ≦ 0.6 contributes to the curved state. Outside this range, the portion of the wind direction deflecting plate 8 from the middle to the front end side does not bend with the same curvature, and therefore, the wind W introduced into the inner case 2 is bent on the curved concave surface of the wind direction deflecting plate 8.
