Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a ventilator device used in an air conditioner for an automobile or the like.

(Prior Art) Conventionally, ventilator devices for automobiles and the like have been used, for example, those shown in FIGS. 4 and 5. In the figure, reference numeral 1 denotes a rectangular cylindrical air blowing case that is connected to an air duct, and a rotation frame 2 that has front and rear openings inside the front end opening of this air blowing case 1.
is supported so as to be freely rotatable in the vertical direction. A plurality of horizontal louvers 3 are provided at a predetermined interval in the front end opening of the rotating frame 2, and a plurality of vertical louvers 4 are provided inside at a predetermined interval on a support shaft. 5, each louver 4 is rotatably supported in the lateral direction, and an interlocking rod 7 is connected to the rear end of each louver 4 via a hinge 6, and a knob 8 is provided at the front of each louver 4. , when one louver 4 is rotated by this knob 8, the interlocking rod 7
The louvers 4 are configured to rotate in synchronization through the louvers 4.

Rotating shafts 9 are coaxially provided on both side walls of the rotating frame 2 and protrude outward, and the rotating shaft 9 on one side is a shaft formed on one side wall of the case 1. It is fitted into the hole 10. Further, a plate-shaped spacer 11 is fitted into the rotation shaft 9 on the other side of the rotation frame 2 through its shaft hole 12, and this spacer 11 is fitted into a bearing frame 13 formed on the side wall of the case 1. Press-fitted and fixed.

Then, use the knob 8 to rotate the vertical louver 4 in the horizontal direction to adjust the horizontal wind direction, and also rotate the rotating frame 2 in the vertical direction to adjust the vertical wind direction. I'm starting to do that.

(Problem to be solved by the invention) In the above-mentioned rotating frame 2, sliding torque is generated by the sliding resistance between the rotating shaft 9 and the shaft hole 12 of the spacer 11, and the rotating position is maintained. ing.

However, according to this structure, the spacer 11 is required separately, which increases the number of parts, and
There is a problem in that the number of assembly steps also increases.

The present invention aims to reduce the number of parts in supporting a rotating frame and to facilitate assembly.

[Structure of the idea]

(Means for Solving the Problems) The present invention provides a ventilator device in which a rotating frame for adjusting the wind direction is rotatably provided in an opening of a blower case by rotating shafts on both sides, in which at least one of the rotating frames is provided. A circular sliding body having elastic deformability in the inner and outer directions is provided on the side part, centering on the rotation axis,
An annular sliding groove with which the edge of the sliding body engages is provided on the inner wall surface of the case facing the sliding body.

(Function) In the present invention, when the rotating frame 2 is rotated with respect to the blower case 1 to adjust the wind direction, the sliding body 21 rotates together with the rotating frame 2, and the edge of the slider body 21 rotates with respect to the blower case 1. It slides into sliding contact with the moving groove 24 with an appropriate pressure, and the rotating frame 2 is held in the rotating position by an appropriate sliding torque during this period.

(Example) An example of the present invention will be described below with reference to FIGS. 1 and 2.

Similar to the devices shown in FIGS. 4 and 5, this device consists of a synthetic resin circuit whose front and rear surfaces are opened in the front end opening of a synthetic resin rectangular tube-shaped ventilation case 1 that communicates with a ventilation duct. A movable frame 2 is supported to be freely rotatable in the vertical direction, and the movable frame 2 is provided with a plurality of horizontal louvers 3 at predetermined intervals in a front end opening, and a plurality of lateral louvers 3 are provided inside. Vertical louvers 4 are supported by a support shaft 5 at predetermined intervals so as to be rotatable in the lateral direction, and an interlocking rod 7 is connected to the rear end of each louver 4 via a hinge 6. , a knob 8 on the front of one louver 4
is provided.

Further, rotation shafts 9 are coaxially provided on both side walls of the rotation frame 2 and protrude outward, and these rotation shafts 9 on both sides are formed in shaft holes formed on both side walls of the case 1. 1
0 is fitted.

In such a device, circular sliding bodies 21 are integrally formed around the rotation shaft 9 on both sides of the rotation frame 2, with the rotation shaft 9 as the center. This sliding member 21 has a substantially dish-shaped elastic portion 22 which is relatively thin and has elastic deformability in the outward and outward directions, and a contact portion 23 is provided at the peripheral edge of the elastic portion 22 .

Furthermore, an annular sliding groove 24 corresponding to the contact portion 23 of the sliding body 21 is formed on the inner wall surface of both side walls of the case 1, with the shaft hole 10 as the center.

Then, the rotating frame 2 is placed in the opening of the blower case 1, and the rotating shafts 9 on both sides are force-fitted into the blower case 1 by the elasticity of the material.
to fit. At the same time, the contact portion 23 of the sliding body 21 is engaged in the sliding groove 24 .

With the above configuration, when rotating the rotating frame 2 with respect to the blower case 1 to adjust the wind direction, the rotating frame 2
At the same time, the sliding body 21 rotates, and the contact portion 23 at the edge slides into sliding contact with the sliding groove 24 of the blower case 1 with an appropriate pressure, and the rotating frame 2 is rotated by an appropriate sliding torque during this time. hold in position.

In addition, in practice, as shown in FIG. 3, by providing slits 25 at appropriate locations in the elastic portion 22 of the sliding member 21, smoother sliding torque can be obtained.

Note that the sliding body 21 may be provided on both sides of the rotating frame 2, or may be provided only on one side.

[Effect of idea]

According to the present invention, when adjusting the wind direction by rotating the rotating frame relative to the blower case, the sliding body rotates together with the rotating frame, and its edge applies appropriate pressure to the sliding groove of the blower case. The rotating frame can be held in the rotating position by a moderate sliding torque during this period, and the rotating frame is provided with a sliding body that engages with the sliding groove of the blower case. This reduces the number of parts and facilitates assembly.
