Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a barrel-type air outlet device used, for example, for air conditioning in a vehicle interior.

[Prior Art] As a conventional air outlet device, for example, an air outlet device for a vehicle, the one shown in FIG. 2 is known. As shown in the figure, a barrel 1 that controls the direction of air blowing is rotatably supported within a retainer 2 that forms an air passage by fitting a barrel shaft 10 into a bearing 20. Further, a felt 3 is attached to the barrel outer wall surface 12 with double-sided tape and is interposed between it and the retainer inner wall surface 22, and the rotation of the barrel 1 is controlled by the sliding resistance between the felt 3 and the retainer inner wall surface 22. Obtaining the operating load at the time.

[Problems to be solved by the invention] As described above, the felt 3 and the retainer inner wall surface 22
In order to obtain sliding resistance, the felt 3 is made thicker than the gap between the barrel outer wall surface 12 and the retainer inner wall surface 22. Therefore, the barrel outer wall surface 12 and the retainer inner wall surface 22 are forced in the direction of moving away from each other. Is receiving. For this reason, the barrel outer wall surface 12 and the retainer inner wall surface 2 are generally molded from resin.
2 had a problem in that it deformed as shown in FIG. 3 when the vehicle interior was heated or when parked under the scorching sun in midsummer, resulting in a reduction in the operating load of the barrel 1.

In addition, the barrel outer wall surface 12 and the retainer inner wall surface 22
Since a non-woven fabric such as felt is used as an intervening material between the barrel 1 and the barrel 1, the fibers may blow out together with the air due to repeated sliding, or may become deformed and thin due to the influence of heat and moisture or over time. There was a problem that the operating load of the machine was reduced.

[Means for Solving the Problems] The present invention solves the problems described above, and includes an air system in which a barrel for controlling the air blowing direction is rotatably supported in a retainer that forms an air passage. In the air outlet device, a disc made of an elastic material is rotatably supported on one of the barrel and the retainer, and the other is rotatably supported on the barrel and the retainer. The present invention is characterized in that an arcuate contact portion is provided that contacts the disc so that the disc rolls as the disc moves.

[Function] With the above configuration, when the barrel is rotated, the elastic deformation force caused by the contact of the disc made of an elastic material with the contact part and the resistance to rotation of the disc become the operating load, and an appropriate operating load is obtained. be able to.

[Example] Next, an example of the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, a barrel 101 that controls the blowing direction of air is rotatably supported by a barrel shaft 110 fitted into a bearing 120 in a retainer 102 that forms an air passage as in the conventional case. has been done.

Further, as shown in FIG. 1B, the barrel inner wall surface 113 and the retainer inner inner wall surface 123 are flush with each other in order to make the flow of the blown air smooth.

A characteristic feature of the present invention is that a disc 118 made of an elastic material such as rubber can be rotated on a disc shaft 116 protruding in a recess 114 provided in the barrel outer wall surface 112 in parallel with the rotation axis of the barrel. The disc 118 is brought into contact with an arcuate contact portion 124 provided on the inner wall surface 122 of the retainer.

With the above configuration, when the barrel 101 is rotated, the disc 118 moves on the contact portion 124 along the disc shaft 11.
6 as the center, the disc axis 116 and the disc 11
Rotational frictional resistance with 8 and contact portion 1 of disk 118
Due to the elastic deformation force caused by contact with 24, a speedy operating load can be obtained.

Note that the present invention is not limited to the embodiments described above; for example, a disc may be provided on the retainer and a contact portion with the disc may be provided on the barrel,
Further, the disc and its contact portion may be provided on both sides of the barrel.

[Effects of the invention] The air outlet device according to the invention not only enables smooth rotation of the barrel, but also prevents the barrel and retainer from being damaged by heat, etc. since the load is applied in a direction parallel to the walls of the barrel and retainer. is less likely to deform, reducing the drop in operating load.
