Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wind direction adjusting device for an automobile or the like.
[0002]
[Prior art]
Conventionally, an assembly structure of a case body and a grill body of a vehicle wind direction adjusting device is disclosed, for example, in Japanese Utility Model Publication No. 7-40919.
In this structure, as shown in FIG. 6, in order to adjust the wind direction at the air outlet of the case body 10 fixed to the instrument panel of the vehicle, the grill body 11 that is pivotally supported by a predetermined angle is pushed in and The guide shaft 13 is guided by a guide groove 13 along an axis orthogonal to the blowout port of the bearing portion, and the support shaft is fitted into the shaft hole.
[0003]
[Problems to be solved by the invention]
In the above prior art, as shown in FIG. 5, the width a of the grill body 11 is equal to or slightly larger than the width b of the air outlet of the case body 10, so that it can be seen integrally in design and improve the wind direction adjustment performance. In the wind direction adjusting device, if the guide groove 13 is along an axis perpendicular to the air outlet, there is a problem that the air outlet and the grill body are damaged.
Further, when the grill body 11 is slightly large, there is a problem that the case body must be divided into two because it cannot be assembled to the integrated case from the front side.
[0004]
[Means for Solving the Problems]
The present invention aims to solve the above problems, and a grill body support shaft projects from the center of the inner surface facing the case body air outlet, and the grill body rotates about the support shaft relative to the case body air outlet. A guide groove that fits into the case body support shaft is formed on the outer surface facing the grill body along the insertion direction, and is inserted into the back of the guide groove. A fitting hole for fitting to the body support shaft is formed, and the width of the grill body is larger than the width of the air outlet of the case body .
[0005]
[Action]
According to the present invention, when the grill body is assembled to the air outlet of the case body, the grill body is rotated obliquely with respect to the air outlet around the rotation shaft, and is formed on the outer surface facing the grill body along the insertion direction. Since the groove is pushed into the projecting shaft on the inner surface facing the case body, the fitting hole formed in the back of the guide groove is fitted to the support shaft, and the grill body is rotated so as to match the outlet, the grill as shown in FIG. The width dimension c with respect to the insertion direction of the body 3 becomes smaller by rotating obliquely with respect to the case body outlet around the support shaft, and the width a of the grill body 3 is smaller than the outlet width b of the case body 10. Even if it is large, it can be assembled from the front side.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the present invention will be described in detail based on one example shown in FIGS.
1 is a case body, 2 is a blower outlet. Reference numeral 3 denotes a grill body inserted into the air outlet 2, and the lateral outer width of the grill body is substantially equal to the lateral inner width of the air outlet of the case body. A support shaft 4 protrudes from the upper and lower central portion of the inner surface of the case body 1 near the air outlet 2. The grill body 3 is inserted into the air outlet 2 in a state of being rotated obliquely with respect to the air outlet about the rotational axis OO, and a guide groove 5 is formed along the insertion direction in the upper and lower central portions of the outer surface. It is. Reference numeral 6 denotes a fitting hole for the support shaft 4 formed in the back of the guide groove 5.
[0007]
Next, an attachment method will be described.
As shown in FIG. 4, the grill body 3 is rotated obliquely with respect to the air outlet 2 of the case body 1 about the rotation axis OO, and the guide groove 5 on the opposing outer surface faces the support shaft 4 on the inner surface facing the case body. As it is, the grill body is pushed in and the guide groove 5 is moved to a position where the guide groove 5 is fitted to the support shaft 4, the fitting hole 6 is fitted to the support shaft 4, and then the grill body 3 is matched with the outlet 2. Rotate to position 11a.
[0008]
【The invention's effect】
According to the present invention, the grill body support shaft protrudes from the center of the inner surface facing the case body outlet, and the grill body is rotated obliquely about the support shaft and about the rotation axis with respect to the case body outlet. The guide groove that fits into the case body support shaft is formed on the outer surface facing the grill body along the insertion direction and is fitted into the grill body support shaft in the back of the guide groove. A hole c is formed, and the width dimension c in the insertion direction of the grill body 3 is reduced by an amount that is rotated obliquely with respect to the case body air outlet about the support shaft. However, even if it is larger than the blower outlet width b of the case body 10, it can be assembled from the front side, so that the assembly is easy, and there is little risk of damage to the blower outlet during assembly.
