An object of the present invention is to solve the above problems and to provide an air conditioning grill in which the curved state of the wind direction deflecting plate is reliably maintained at a predetermined position.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a main body member with a plurality of bendable wind direction deflecting plates, one end of which is axially supported, and the other end of which is provided. The wind direction deflecting plate is connected to a connecting member that connects the plurality of wind direction deflecting plates, and another wind direction deflecting plate is disposed integrally with the main body member on the front surface of the wind direction deflecting plate in a direction orthogonal to the wind direction deflecting plate. An operation member having a fulcrum on the front wind direction deflecting plate and an operating point on the connecting member is provided, and resistance applying means for applying a rotation resistance to the operation member is provided.

[Operation] By adopting the above configuration, when the operation member is rotated, the operation member rotates about the fulcrum shaft and the operation shaft moves the connecting member, so that the wind direction deflecting plate on the rear surface that can be curved The rear end portion moves and the same wind direction deflecting plate bends, and the wind from the rear of the main body member flows along the curved wind direction deflecting plate, gradually changes its direction according to the curved portion, and then the wind direction deflecting member located in front of it. The air flow deflecting plate that flows forward along the plate and blows out in a predetermined direction from the front end portion of the main body member, and the bendable wind direction deflecting plate is held in a predetermined curved state by a resistance applying unit that applies rotational resistance to the operating member.

[First Embodiment] An embodiment in which the present invention is embodied in an air-conditioning grill mounted on an instrument panel in a vehicle will be described below with reference to Figs.

As shown in FIGS. 1 to 3, in the front part of a ventilation duct 1 as a rectangular parallelepiped main body member having holes in the front and rear, three wind direction deflecting plates 2 made of a resin that does not bend in the lateral direction and has rigidity are provided. An inner case 3 is disposed as a main body member having a. The inner case 3 is rotatably supported by the air duct 1 by a shaft 4.

Behind the wind direction deflecting plate 2, four bendable wind direction deflecting plates 5 are arranged at substantially equal intervals in the vertical direction orthogonal to the wind direction deflecting plate 2. The front end portion of the wind direction deflecting plate 5 has flat plate-like holding plates 6a, 6 which are integrally arranged above and below the inner case 3.
It is supported by a shaft 7 fixed between b. Therefore, the coaxial 7 is reinforced by the holding plates 6a and 6b and the wind direction deflecting plate 2 at five points respectively, so that the wind direction deflecting plate 5 is surely bent.

Further, the rear end portion thereof is connected to the connecting rod 8 as a connecting member connecting the four wind direction deflecting plates 5 at the central portion thereof and the shaft 9 provided on the connecting rods 8a and 8b connecting vertically. It is fixed. As the material of the bendable wind direction deflecting plate 5, rubber such as chloroprene rubber, synthetic resin such as polyvinyl chloride, polypropylene and polyethylene, and metal such as stainless steel are used.

Along the rearward extension lines of the four wind direction deflecting plates 5, another resin-made wind direction deflecting plate 10 having rigidity that does not bend is fixed to the upper and lower connecting rods 8a and 8b. The rear end portion of the wind direction deflecting plate 10 is always in the same direction as the wind W from the rear of the air duct 1. The wind direction deflecting plate 10 is supported by the shafts 9, and the four shafts 9 have the same direction.
They are reinforced by each so as not to hinder the bending of the wind direction deflecting plate 5 located in the front thereof.

An operation lever 13 as an operation member having an action shaft 11 as an action point on the connecting rod 8 and a fulcrum shaft 12 as a fulcrum on the wind direction deflecting plate on the front surface is provided substantially at the center of the inner case 3. It is provided. When the operation lever 13 is moved in the left-right direction from the front of the inner case 3, the operation lever 13 rotates about the fulcrum shaft 12, and the connecting rod 8 connected by the action shaft 11 moves in the opposite direction. However, the wind direction deflecting plate 5 is curved between the front and rear shafts 7 and 9. At this time, the end portion of the wind direction deflecting plate 5 on the shaft 9 side is in the same direction as the wind W from the rear of the air duct 1.

Further, as shown in FIG. 4, in the gap between the operation lever 13 near the fulcrum shaft 12 of the operation lever 13 and the wind direction deflection plate 2 on the front surface,
An elastic member 14 is provided as a resistance applying means. The elastic member 14 presses both the operating lever 13 and the wind direction deflecting plate 2 on the front surface to give a frictional resistance between them, so that the curved wind direction deflecting plate 5 on the rear surface returns to the original force. On the contrary, the same wind direction deflecting plate 5 can be held in its curved state.

The left and right ends of the connecting rods 8a, 8b have one end having the connecting rods 8a, 8b.
The operation lever 13 is provided with an auxiliary rod 17 which is rotatably supported by the holding rod 6a, 6b and the other end of which is supported by a shaft fixed to the holding plates 6a and 6b.
And form a parallel link.

Wind direction deflecting plates 2, 5, 1 arranged in the air duct 1
0, the connecting rods 8, 8a, 8b, the holding plates 6a, 6b, and the like are integrated with the inner case 3, and are configured to rotate vertically about the shaft 4 as a unit.

The operation and effect of the air-conditioning grill configured as described above will be described.

First, as shown in FIG. 1, when the operation lever 13 is moved from the center to the right to a predetermined position, the operation lever 13 rotates about the fulcrum shaft 12, so that the rear end portion of the operation lever 13 is rotated. The connecting rod 8 connected by the action shaft 11 rotates to the left. At that position, the wind direction deflecting plate 5 is curved to the left between the working shaft 11 at the rear end and the shaft 7 at the front end in a protruding shape. At this time,
The curved wind direction deflecting plate 5 exerts a force for returning to the operation lever 13 to the original position.

On the other hand, as shown in FIG. 4, the elastic member 14 provided in the gap between the operation lever 13 and the wind direction deflecting plate 2 on the front surface in the vicinity of the fulcrum shaft 12 of the operation lever 13 is provided on the operation lever 13 and the front surface. Since the wind direction deflector 2 is being pressed, the operating lever 13
Is reliably held as it is at the position where the curved wind direction deflecting plate 5 has moved to the right against the force to return to its original position, and at the same time, the curved wind direction deflecting plate 5 is held in that curved state. In addition, an appropriate operation load is applied to the operation lever 13 to improve the operation feeling.

Further, the wind direction deflection plate 10 located behind the wind direction deflection plate 5 is
It keeps the front-back direction. Therefore, the wind W from the rear of the blower duct 1 smoothly flows to the right along the curved windward deflector 5 via the wind deflector 10 and blows out from the front end of the blower duct 1 via the front wind deflector 2. .

Next, when the operation lever 13 is rotated upward, the wind direction deflection plate
The inner case 3 in which 2, 5, 10 and the like are integrated rotates upward.
Therefore, the wind W from the wind direction deflecting plate 5 on the rear surface flows upward along the wind direction deflecting plate 2 on the front surface and blows out from the front end portion of the air duct 1.

When the operation lever 13 is moved to the left, contrary to the above, the connecting rod 8 is rotated to the right, and the wind direction deflecting plate 5 is curved to the right in a protruding shape. Therefore, the wind W from the rear of the air duct 1 smoothly flows to the left along the curved air flow deflector 5 via the air flow deflector 10 and blows out from the front end of the air duct 1 via the air flow deflector 2 on the front surface. .

As described above, in the air-conditioning grill of the present embodiment, when the operation lever is moved and operated, the curved wind direction deflector plate returns to its original position, but the operation lever does not return to the original position, and the wind direction deflection plate does not return to its original position. The curved state of the plate 5 is reliably held at an arbitrary position. Moreover, the operation force of the operation lever 13 is moderate, and the operation feeling is improved.

In addition, the wind W at which the wind W introduction side end of the wind direction deflecting plate 5 is introduced
Since the direction is the same as the direction of, noise generation is reduced especially when a strong wind is blown out. Also, one operating lever 13
By operating left and right or up and down, the wind W can be easily blown out in a desired direction.

The present invention is not limited to the first embodiment described above, but may be configured as follows.

That is, as shown in FIG. 5, as the resistance applying means, the operation lever 13 itself may be provided with a pressing portion 13a for sandwiching the front wind direction deflecting plate 2 in the vicinity of the fulcrum shaft 12.

Further, as shown in FIGS. 6 (a) and 6 (b), the operation lever
An elastic member 18, such as a leaf spring, is provided on 13 and the wind direction deflecting plate 2 on the front surface is provided.
Alternatively, the fulcrum shaft 12 formed integrally with may be pressed.

Further, as shown in FIGS. 7 (a) and 7 (b), the fulcrum shaft 12 itself formed integrally with the wind direction deflecting plate 2 on the front surface is provided with a notch at the end thereof to expand in the outer peripheral direction. Expansion part
It is also possible to adopt a structure of 12a and press the expanded portion 12a against the hole 19 in the fulcrum shaft 12.
