Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilator louver for an automobile in which an operating knob can be easily slid.

[0002]

2. Description of the Related Art A driver's seat of an automobile is provided with an air outlet for an air conditioner for air conditioning the interior of the vehicle. On the instrument panel 100 of the driver's seat, as shown in FIG.
02, 103 for side demister, 1 for ventilation
04, 105, heaters (not shown) are provided, and ventilation outlets 104, 105 are provided with
A ventilator louver 106 for adjusting the wind direction,
107 is provided.

The ventilator louvers 106 and 107 are ventilating outlets 10 at the center and both sides of the driver's seat.
The wind direction can be changed by adjusting the orientation of the vertical and horizontal fins.

FIG. 11 shows a method of changing the vertical wind direction by a ventilator louver 110 in which a front fin 108 is arranged in the front and a rear fin 109 is arranged in the rear in a direction orthogonal to each other. The ventilator louver 110 is
As shown in FIG. 12, a plurality of rear fins 109 are attached to the case 1
The shaft portions 112 provided on both sides of the rear fins 109 are rotatably supported on the wall surface of the case 111 by arranging them at regular intervals in the up-down direction in 11. The rear fins 109 are connected at their rear end portions via a connecting bar 113, and their directions can be simultaneously changed by operating the operation knob 114. The operation knob 114 is slidably provided on one of the front fins 108, and a bifurcated operation rod 115 provided at the tip of the operation knob 114 is engaged with one of the rear fins 109. .

Then, the operation knob 114 is rotated left and right to change the direction of the front fin 108 to the left and right, and the operation knob 114 is rotated.
Slide up and down and the rear fin 1 through the operating rod 115.
The direction of 09 is changed to the vertical direction.

[0006]

However, when operating the operating knob 114 in the vertical direction, if there is any play between the operating knob 114 and the front fin 108, as shown in FIG. However, there is a problem in that it becomes tilted and gets stuck, which makes it difficult to move.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and to provide a ventilator louver for an automobile in which the tilt of the operation knob can be prevented and the operation knob can be smoothly moved.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention rotates a plurality of front fins and a plurality of rear fins in a ventilator case in directions orthogonal to each other around respective pivot shafts. In a ventilator louver for an automobile in which the front fin and the rear fin are rotatably operated by an operation knob, the operation knob is slidably provided on the front fin and a rear portion is provided at a tip end portion of the operation knob. This is because an engaging portion that engages with the fin is provided and an arm portion that is engaged with the back portion of the front fin is provided on the operation knob.

Further, according to the present invention, a plurality of front fins and a plurality of rear fins are provided in a ventilator case so as to be rotatable about respective rotation axes in directions orthogonal to each other. In a ventilator louver for an automobile in which the operation knob is rotatably operated, the operation knob is slidably provided on one of the front fins, and the tip portion of the operation knob is engaged with one of the rear fins. Is provided, and the operation knob is provided with an arm portion that is locked to the back portion of the front fin, and the arm portion has an elastic repulsion action to elastically press the back portion of the front fin. is there.

[0010]

When the operation knob is slid along the front fin, the rear fin changes its direction around the rotation axis by the engaging portion of the operation knob. At this time, since the operation knob is locked to the back of the front fin by the arm, it can be slid without tilting.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

1 to 3, reference numeral 1 denotes a ventilator louver provided at air outlets on both sides of the instrument panel. This ventilator louver 1 has a front fin (vertical fin) 3 inside a case 2.
And the rear fins (horizontal fins) 4 in directions orthogonal to each other,
A plurality of sheets are axially supported at regular intervals, and the front fins 3 and the rear fins 4 are pivotally supported by the connecting rods 5 and 6 so as to interlock with each other.

Reference numeral 7 denotes an operation knob slidably provided on the front fin 3'in the central portion, and the operation knob 7 has a holding portion 8
And a bifurcated plate 9 attached to the tip of the holding part 8.
a and 9b, and the plates 9a and 9b
It is composed of arm portions 10 and 11 which are vertically extended.

The sandwiching portion 8 has a through hole 8a formed in the up and down direction through which the front fin 3'is inserted. The through hole 8a is formed in the vertical direction.
It is supported by the front fin 3'via a. Through hole 8a
Is provided with a claw portion 12 on one side of the inner side surface and an R portion 13 on the other side opposite to the inner side surface.
The holding portion 8 is attached to the side surface 14 of which the portion 13 has a slit or a concave shape of the front fin 3 '. The engaging portion 9 is provided with vertically opposed plates 9a and 9b, and the plates 9a and 9b are arranged at the tip of the holding portion 8 so as to sandwich both sides of the central rear fin 4 '. The central rear fin 4'has a semicircular cutout 15 formed on the plate surface, and the plate 9a,
An engagement portion 16 that engages with 9b is provided.

The arm portions 10 and 11 are provided with R portions 10a and 11a at their distal ends, which are directed toward the side of the through hole 8a. The R portions 10a and 11b are the back portions 3a of the front fins 3 '.
Elastically abuts against. The arm portions 10 and 11 are formed such that the R portions 10a and 11b are located in front of the back portion 3a of the front fin 3 ', and the R portion 10a is brought into contact with the back portion 3a of the front fin 3'. I try to get the resilience.
