DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilator provided at an air outlet of an air conditioner for adjusting a wind direction.

[0002]

2. Description of the Related Art Conventionally, for example, a ventilator for deflecting air blown from an air conditioner for air-conditioning the interior of a vehicle has been known. A housing body to which the wind direction deflecting blades are attached is rotatably supported on a case body by a rotating shaft, and an occupant or the like operates the housing body to obtain an arbitrary wind direction. It can be easily done with a response. For example, Japanese Utility Model Application Laid-Open No. 2-72120
In the publication, a spacer made of a truncated cone-shaped elastic body is interposed in order to obtain such an appropriate operation feeling.

[0003]

However, in the above-mentioned prior art, there is a problem that it is difficult to insert the frusto-conical elastic body when assembling the housing body and the case body.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to provide a spacer having pivot shafts projecting from both sides of a housing for adjusting the wind direction and having a pivot bearing hole and an engagement projection. Is inserted into the rotating shaft, and this is fitted to the case body, the spacer is inserted into the concave part on both sides of the case body, and the engaging projection is fitted and locked in the engaging hole of the concave part. A projection is provided on at least one side of the wind direction adjusting housing body, and the projection is located to face the spacer in a predetermined rotation angle range of the wind direction adjusting housing body.

[0005]

The rotation bearing hole of the spacer is fitted on the rotation shaft of the wind direction adjusting housing, the spacer is inserted and fixed in the spacer insertion recess of the case body, and the wind direction adjusting housing is rotated to form the protrusion. The slider can be brought into contact with the upper surface of the spacer and stopped at an arbitrary angle by an appropriate operation torque.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail with reference to the drawings. 1 to 4 show a first embodiment of the present invention. FIG. 1 is an exploded perspective view. 1 is a front finisher, 2 is a housing for adjusting the wind direction, and a horizontal fin 3 integrally formed, a vertical fin 4 formed and assembled separately, and an operation knob 5 of the vertical fin 4 are attached. The rotating shaft 6 and the rotating shaft 6 are provided on both outer surfaces 2a.
The projections 7 are provided at predetermined intervals. Reference numeral 8 denotes a case body, which has spacer insertion recesses 8b formed at the front portions of both sides 8a to protrude outwardly and provided with spacer locking holes 8c. Reference numeral 10 denotes a spacer made of an elastic body, which is a rotation bearing hole 10a in which the rotation shaft 6 is fitted and a locking projection 10 which is locked in the spacer locking hole 8c.
b and the vertical groove 10c are provided.

At the time of assembling, as shown in FIGS. 2 and 3, the housing 2 for adjusting the wind direction is inserted into the rotation bearing hole 10a of the spacer 10.
The rotation shaft 6 is fitted, the spacer 10 is inserted into the spacer insertion concave portion 8b, and the spacer 10 is deformed inward at the vertical groove 10c. Stop and fix to the case body 8. The protrusion 7 is positioned so as to be out of the plane of the spacer 10. It is preferable that the spacer 10 and the wind direction adjusting housing body 2 have a rotation limit angle in a state where the wind direction adjusting housing body 2 is incorporated in the case body 8. Next, the housing body 2 for adjusting the wind direction
Is rotated to a predetermined position. At this time, the protrusion 7 is
Slidably presses against the outer surface of the device to generate sliding resistance. Further, an operation torque is generated by the rotation resistance between the rotation shaft 6 and the rotation bearing hole 10a, and the operation can be stopped at a desired angle.

FIG. 5 shows a second embodiment in which the spacer 10 'is not provided with a vertical groove, and the projection 7 is provided with an inclined portion 7a for guiding.

In each of the above embodiments, the projections 7 are provided on the outer surfaces 2a on both sides of the housing 2 for adjusting the wind direction, but they may be provided on any one of the outer surfaces. Further, in each of the above embodiments, the housing body 2 for adjusting the wind direction and the case body 8 are made of ABS resin, the vertical fins 4 are made of polypropylene or PET resin, and the spacers 10, 10 'are made of polyacetal.

[0010]

According to the present invention, a rotating shaft is projected from both sides of the housing for adjusting the wind direction, and a spacer having a rotating bearing hole and an engaging projection is inserted into the concave portion on both sides of the case body, and the engagement is achieved. The projection is fitted and locked in the engagement hole of the recess, and the rotation shafts on both sides of the housing for adjusting the wind direction are fitted in the rotation bearing holes of the spacer.
Projections are provided on at least one side of both sides of the wind direction adjusting housing so as to be spaced apart from the rotating shaft by a predetermined distance, and the protrusions are located on the facing surface of the spacer within a predetermined angle range of the wind direction adjusting housing. As a result, the spacer and the housing for adjusting the wind direction can be mounted smoothly and reliably, and the housing for adjusting the wind direction can be prevented from coming off.
