Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a grill structure of an air conditioner suitable for use in an air conditioner for a vehicle such as an automobile.

(Prior Art) An air conditioner mounted on a vehicle such as an automobile blows cold air or hot air through an opening of a ventilator box provided on an instrument panel or a console. The structure will be explained with reference to FIG.
Reference numeral 1 is an instrument panel of an automobile, and 2 is a console portion thereof. A ventilator case 3 is fitted and attached to the console section 2. The ventilator case 3 is provided with a louver body 5 in which a louver fin 4 is rotatably provided. A plurality of louver fins 4 are provided, and they are joined by a rod 6 so as to move integrally.

As shown in FIG. 4, a rotating shaft (louver shut) 7 of the louver body 5 projects outward from one side of the ventilator case 3. Then, both ends of the rotary shaft 7 protruding from the ventilator case 3 are fixed with bolts 8 at the console 2
The intermediate portion of the leaf spring 9 fixed to a part of the above is in pressure contact.
Thereby, an appropriate frictional force is applied to the rotation of the rotation shaft 7 of the louver body 5 in the circumferential direction, and the moderation is maintained.

(Problems to be Solved by the Invention) In the conventional grill structure of the air conditioner having the above-described structure, the leaf spring 9 is pressed against the rotating shaft 7 serving as a support shaft for rotating the louver body 5. Therefore, there is a problem that a leaf spring and a bolt 8 for mounting the leaf spring are required, resulting in an increase in the number of parts and an increase in cost due to the number of man-hours for assembling (as another example using the leaf spring. See Japanese Utility Model Publication No. 52-37550). The present invention has been made for the purpose of solving this problem.

(Means for Solving Problems) As a means for solving the above problems, the present invention rotatably supports a louver body 5 having louver fins 4 provided inside a ventilator case 3, and the louver body 5 In the air conditioner in which the rotary shaft 7 of the rotary shaft 7 is projected to the outside of the ventilator case 3, the ventilator case 3 of the rotary shaft 7 is
An arm 11 having a hemispherical portion 10 formed at the tip thereof is integrally provided on the protruding portion from, while a concave portion 12 engaging with the hemispherical portion 10 is provided in a portion of the ventilator case 3 close to the arm 11. The arc-shaped groove 13 is formed.

(Operation) With such a structure, when the rotating shaft 7 is rotated with respect to the ventilator case 3, the hemispherical portion 10 provided at the tip of the arm 11 integral with the rotating shaft 7 has an arcuate groove. When moving inside the louver 13, the elastic force of the arm 11 sequentially engages with the concave portion 12 in the arc-shaped groove 13, so that the movement of the louver body 5 can be kept moderate.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. First, in FIG. 1, 3 is a ventilator case, which is provided at a position as shown in FIG. 3 as an example. A plurality of louver fins 4 are provided inside the ventilator case 3 by connecting them with a rod 6. By moving any one of the louver fins 4 in the horizontal direction, the whole direction can be changed. There is. These louver fins 4 are supported by the louver body 5 at the inner portion (not shown). The louver body 5 is rotatably supported by the ventilator case 3.

The louver body 5 is provided with a rotating shaft 7 on one side, and the rotating shaft 7 is projected to the outside from the side portion of the ventilator case 3. An arm 11 having a hemispherical portion 10 formed at the tip is integrally provided on the protruding portion of the rotating shaft 7 from the ventilator case 3, while the part of the ventilator case 3 close to the arm 11 is provided. An arc-shaped groove 13 provided with a recess 12 that engages with the hemispherical portion 10 is formed. As shown in FIG. 2, the hemispherical portion 10 provided at the tip of the arm 11 in the assembled state is located in the groove 13 and comes to the position of the recesses 12 provided in the groove 13 at appropriate intervals. When it is opened, it engages with the recess 12.

In the grill structure of the air conditioner thus configured, when the louver body 5 is rotated about the rotation shaft 7 in order to change the direction of the blown air in the vertical direction, the arm
The hemispherical portion 10 formed at the tip of 11 moves in the groove 13. As a result, the louver body 5 rotates on the correct locus. By engaging the hemispherical portions 10 with the recesses 12 provided in the groove 13 at appropriate intervals, the hemispherical portion 10 can be stopped with a moderation in a predetermined time. By engaging the hemisphere 10 with the recess 12,
The direction of the louver body 5 does not change due to the blowing air. Since the structure is simple and the number of parts is smaller than the conventional one, the number of assembling steps can be reduced and the cost can be reduced.
