Description

[Detailed description of the invention] This invention relates to a ventilator installed in the instrument panel of an automobile with a wind direction adjustment device. The present invention relates to a ventilator which is provided with a flexible frame body and whose air direction is adjusted by means of an air outlet opened in the frame body.

In recent years, automobile ventilators have come to serve not only the purpose of ventilating the interior of the car, but also the purpose of providing a cooling sensation to the passengers. I'm getting hired.

Accordingly, as a conventional structure of the above-mentioned wind direction adjustment device, there is a mode in which a grill installed in the air outlet is rotated.
This aspect has the disadvantage that there is a limit to the angle at which the wind direction can be adjusted, making it difficult to blow air over a wide range.

In addition, as another aspect, there is one in which the frame body with the ventilation opening is rotatable via a spindle, and in this aspect, it is possible to blow air over a relatively wide range, but When the frame rotates, the edge of the frame protrudes onto the surface of the instrument panel, which has the disadvantage of causing danger when the vehicle suddenly stops.

The purpose of this invention is to eliminate the above-mentioned disadvantages by making it possible to change the posture of the air outlet with respect to the changing surface of the instrument panel, in view of the problems of the conventional ventilator described above, especially due to the limited range of adjustment of the wind direction. The object is to provide an excellent ventilator without disadvantages.

The configuration of this invention in accordance with the above purpose is that air is blown into the vehicle from the air outlet of the frame body installed in the opening provided in the curved surface of the instrument panel, and the air outlet is arranged in the position of the frame body. The gist is that the airflow direction is moved steplessly or in a clip-flop manner within the opening by the displacement movement, and the airflow direction can be adjusted over a wide angle by following the shape of the changing surface.

Next, an embodiment of this invention will be described below based on the drawings.

In Fig. 1, 1 is an instrument panel, the shape of which is an upwardly inclined surface 2 at the top, a vertical front surface 3 at the front,
Furthermore, the lower part has a downwardly inclined surface 4, and instruments 5 and a steering wheel 6 are installed in a portion corresponding to the driver's seat.

Thus, the ridge line I from the upper inclined surface 2 to the vertical front surface 3 corresponds to a changing surface part, and openings 8 having sufficient vertical dimensions are provided at several predetermined locations across the ridge line I. , the opening 8 is equipped with a ventilator 9 of this invention.

The structure of the ventilator 9 is as shown in detail in FIG. An air outlet 12 is opened only on the surface where the air outlet is opened, and a predetermined array of grilles 13 is provided within the air outlet 12.

The upper and lower surfaces of the frame 10 on which the air outlet 12 is opened, that is, the portions corresponding to both side surfaces of the trapezoidal cross section, are used as an upper shielding plate 14 and a lower shielding plate 15.
The inside is connected to a bellows tube 1T via a ventilation wall 16, and communicated with a blower device (not shown) through a blower tube 18 connected thereto.

Here, the above-mentioned rotation support device 11 will be explained.
As shown in the Western movies shown in FIGS. 2 and 3, this device includes a cross-sectional fixed guide 19 that is fixed to a bracket (not shown) in the instrument panel 1 through a mounting hole 21 drilled in a horizontal surface 20. The frame 1 is attached to the implant sleeve 25 of the bearing plate 24, which is slidably provided in the guide groove 22 of the upright portion of the fixed guide 19 via a spring 23.
A protruding pin 27 is fitted into the side plate 26 of 0.

Note that 28 and 29 are stoppers for preventing rotation of the frame 10, and are appropriately provided inside the instrument panel 1.

The grille 13 is pivotably supported within the air outlet 12 and is rotatable so that the direction of the airflow can be finely adjusted.

In the above configuration, when an operating device (not shown) is operated when it is necessary to blow air into the car, cool air, etc. is blown into the car from the air outlet 12 via the ventilation tube 18 and the bellows tube 1γ.

The operation for switching the air blowing direction by changing the posture of the frame 10 is as follows.

That is, when blowing air upward from the instrument panel 1, as shown in FIGS.
Rotate 0 (.

In this state, the lower shielding plate 15 of the frame 10 closes off the lower part of the opening 8 of the instrument panel, that is, the vertical front 3 portion.

Next, when switching the air direction toward the lower part of the vehicle interior, by manually pushing the frame 10 into the instrument panel 1 and displacing the air outlet 12 downward, the bearing plate 24 slides against the fixed guide 19. Frame side plate 2
The protruding pin 27 of No. 6 moves from position A to position B shown in Fig. 4.5.
It retracts against the spring 23 until the end.

Therefore, when the rotation center is located at the position B, the frame 10 is smoothly rotated via the bearing sleeve 25,
After the rotation, by removing the external force, the center of rotation by the pin 27 is returned to position A by the amount of spring deflection,
As shown in FIG. 5, the air outlet 12 is flush with the vertical front surface 3 of the instrument panel, and the upper inclined surface 2 of the opening 8
The side portion is blocked by the upper blocking plate 14 and sent only to the lower part of the vehicle interior.

That is, by manually switching the flip-flop, the air blowing direction can be adjusted over a wide range of vertical angles as shown in FIG. 6.7, and fine adjustments can be made by rotating the grille 13.

Note that the embodiment of this invention is not limited to the above-mentioned embodiments, and other designs are possible. For example, when the deformed surface portion of the instrument panel is a circularly curved surface, the frame body is attached to the instrument panel. The position of the air outlet may be set to be displaced in a stepless manner by allowing sliding displacement using a guide provided in the air outlet.

As described above, according to this invention, the frame provided in the opening formed in the deformed surface of the instrument panel is pivotally connected to the instrument panel via the rotation support device. The air outlet installed on one side of the exposed surface of the frame is rotatable over the entire opening area, and the air direction can be adjusted over a wide range of angles to follow the changing surface of the instrument panel, making it perfect for ventilation inside the car or during summer driving. Sufficient ventilation can be obtained when a cool feeling is required, and the opening area of the ventilation opening can be secured as wide as possible without interfering with the design of the instrument panel, which is an excellent effect.

Furthermore, since the blow tube and the frame body are connected to each other through the bellows tube, the air is blown without leakage when the wind direction changes.

Another advantage is that the air outlet does not need to protrude from the surface of the instrument panel and can provide wide-angle ventilation, so the air outlet does not become a dangerous area in the event of a sudden stop.
