DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind direction adjusting device mounted on an instrument panel or the like of an automobile.

[0002]

2. Description of the Related Art As a conventional wind direction adjusting device, for example, a device as disclosed in Japanese Patent Application Laid-Open No. Hei 8-197940 is known. In this type of wind direction adjusting device, two sets of wind direction adjusting louvers are arranged side by side in a case for air-conditioning air blowout mounted on an instrument panel of an automobile, and lower ends of rotation axes of the left and right wind direction adjusting louvers. The gears provided in the above are engaged with each other. And by turning the dial exposed from the case,
The case is closed by manually operating the gear.

[0003]

However, in such a conventional technique, even if the dial is rotated,
It is difficult to determine where the closed position is, and improvement is required. In addition, it is difficult to determine to which direction the dial can be turned to be shut down with less operation, and improvement in this respect is required.

The present invention has been made by paying attention to such a conventional technique, and has disclosed a wind direction adjusting device in which it is clear that the case is closed and which operation is more efficient is obvious. To provide.

[0005]

According to the first aspect of the present invention,
A case capable of blowing air and having an outlet at a leeward side end, a finisher covering the periphery of the outlet of the case, and a fin disposed in the case and capable of controlling the direction of air blowing in an appropriate direction. It is possible to switch between a closed position, which is disposed in the case and closes the air blown into the case so as not to blow out from the outlet, and an open position which blows the wind blown into the case from the outlet. And a rotary shut dial that is operable to move the valve mechanism between a closed position and an open position, can change the direction of the fin, and is partially exposed from an opening of the finisher. An adjusting device, wherein the shut dial has a center mark indicating a center position on the indoor side when the fin is in a neutral position, and the center mark A guide mark indicating the shut direction of the valve mechanism in a position sandwiching the is arranged respectively, the guide mark is arranged so as not to be exposed to the passenger compartment at the same time.

According to the first aspect of the present invention, the two guide marks of the shut dial are not exposed at the same time.
By turning the shut dial in accordance with only one exposed guide mark, it is clear that the valve mechanism has been closed and the valve mechanism can be closed with less operation.

In the invention according to a second aspect, a closing mark indicating that the valve mechanism is closed is provided around the opening of the finisher.

According to the invention described in claim 2, the closing mark can appeal to the occupant that the valve mechanism can be closed by operating the dial in the direction of the closing mark.

According to a third aspect of the present invention, the guide mark exposed in the vehicle interior is a substantially arrow-shaped mark indicating the operation direction of the shut dial which can be set to the closed position with less operation.

According to the third aspect of the present invention, since the guide mark has a substantially arrow shape, the operation direction in which the valve mechanism can be closed with less operation can be recognized at a glance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to FIGS. In addition, in FIG.
The direction is the width direction (left-right direction), the H direction is the up-down direction, and the Y is the longitudinal direction (front-back direction). The longitudinal direction Y is a blowing direction, Y1 is leeward, and Y2 is leeward.

A ventilator 1 as a “wind direction adjusting device” according to this embodiment is installed on both sides 3 of an instrument panel 2.

The ventilator 1 includes a well-known case (not shown) capable of blowing air and having an outlet at a leeward end, a finisher 4, vertical fins 5 and horizontal fins 6.
And a well-known valve mechanism (not shown) and a shut dial 9
And an operation knob 11 that can change the wind direction via the connecting mechanism 10 of the horizontal fin 6.

The finisher 4 has an outlet of a well-known case (not shown), that is, an outlet 4a that covers the periphery of the leeward Y1 side. The vertical fins 5
A plurality of such cases are arranged on the leeward side of the case (not shown), and the direction of air flow can be controlled in the left-right direction X. A plurality of horizontal fins 6 are provided on the leeward Y1 side of the case (not shown), and the direction of air blowing can be controlled in the vertical direction H.

The well-known valve mechanism is disposed in the case and is closed at a position where the air blown into the case is closed so as not to blow out from the outlet, and the outlet blows the air blown into the case. It is possible to switch to an open position where the air is blown out from the opening.

The rotary shut dial 9 can operate the valve mechanism to a closed position and an open position, change the direction of the vertical fins 5 via a connecting mechanism 7, and open the valve mechanism from the opening 8 of the finisher 4. Partially exposed.

The shut dial 9 has an operating portion 16 and a gear portion 17 formed in an arc shape around a shaft portion 15 coaxial with the vertical fins 5, and a connection for connecting the shaft portion 15 and the gear 17 to each other. And part 18. The operation unit 16
A central concave portion 19 in which the vertical fins 5 are formed in a neutral position, that is, a position in which the vertical fin 5 cannot swing right and left, and two vertical fins 5 formed on the left and right at an angle θ of 30 degrees with respect to the central concave portion 19. A left side recess 20 and a right side recess 21 are formed. The center concave portion 19 is formed with a center mark 12 indicating a center position on the indoor side when the vertical fin 5 is at a neutral position, that is, at a position where the vertical fin 5 cannot swing right and left. In the left side recess 20 immediately adjacent to the center recess 19,
A guide mark 13 indicating the shut-off direction of the valve mechanism is formed, and a guide mark indicating the shut-off direction of the valve mechanism is provided in the right side recess 21 next to the right side recess 21 immediately adjacent to the central recess 19. The guide marks 13 and 14 are located at positions sandwiching the center mark 12.

The opening 8 of the finisher 4 is formed so that both of the guide marks 13 and 14 have a width such that they are not simultaneously exposed to the vehicle interior. Will be covered. The guide marks 13 and 14 exposed in the vehicle interior are substantially arrow-shaped marks indicating the operation direction of the shut dial 9 that can be set to the closed position with less operation.

On both edges around the opening 8 of the finisher 4, a closing mark 22 indicating that the valve mechanism is closed,
22.

The gear 17 has a threaded portion 23 formed therein.

Since the embodiment of the present invention has such a configuration, the guide marks 13 and 14 of the operation portion 16 of the shut dial 9 are not exposed from the opening 8 at the same time. If the operation unit 16 of the shut dial 9 is rotated according to 13 or 14,
It becomes clear that the valve mechanism has been closed. Further, since the guide mark 13 or 14 has a substantially arrow shape, it is possible to recognize at a glance the operation direction in which the valve mechanism can be closed with less operation.

In the vicinity of the opening 8 of the finisher 4, a closing mark 22, 22 indicating that the valve mechanism is closed.
The closing mark 22 can appeal to the occupant that the valve mechanism can be closed by operating the shut dial 9 in the direction of the closing mark 22.
