Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is particularly applicable to vehicles.
The present invention relates to a device in which an air conditioner operation switch is incorporated in an air conditioner outlet.

[0002]

2. Description of the Related Art Since a conventional air conditioner operation panel in a vehicle is provided with a large number of operation switch knobs and an air conditioner operating state display portion, the area of the air conditioner operation panel in the instrument panel is relatively small. There is a problem that the size of the instrument panel is limited and the degree of freedom in designing the instrument panel is limited, and it is not always easy to control the air conditioner using the knob for the operation switch.
As a solution to this problem, the air conditioner operation panel is equipped with a door to cover some of the operation switch knobs to reduce the number of apparent operation switch knobs, or the operation switch knobs are made more versatile. Although it has been considered to reduce the number of knobs, in terms of operability of the switch knobs, it has been said that no progress has been made.

[0003]

SUMMARY OF THE INVENTION The present invention reduces the area occupied by the air conditioner operation panel by eliminating the operation switch knob from the air conditioner operation panel, and increases the degree of freedom in design around the air conditioner operation panel. At the same time, the operability of the knob for the operation switch is improved.

[0004]

To achieve this object, an air conditioner outlet device according to the present invention includes a plurality of louvers installed in the air outlet of the air conditioner, and the air conditioner attached to a part of the louver. The operation switch has a pin attached to the louver other than the part and extending to the outside of the louver to suppress the rotation of the louver.

[0005]

In other words, since the pin attached to the louver in the air conditioner outlet extends outside the louver to suppress the rotation of the louver, the operation of the other louvers in the air conditioner outlet is also controlled. Even if the switch is operated, the adjustment of the wind direction by each louver is not inadvertently changed, and therefore, the operation of the operation switch can be surely and easily performed.

5, 16, 17, 18 are louver elements 141-143, 151-153, 161-163, 1 respectively.
71-173, 181-183, and the vertical fins 30 and the like can easily adjust the cold air or the hot air blown from the air conditioner outlets 2 and 3 in both the vertical direction and the horizontal direction. Since the structure is simple as compared with the case where vertical and horizontal adjustments are performed by separate louvers, they can be manufactured at low cost.

Further, when the central knob 162 is pushed, the central portion of the pin 42 is further pushed and bent in the lateral direction via the operating rod 41, and the vertical rotation restraining action with respect to the louver frames 12 and 13 is suppressed. Louver 14, 1
When the horizontal rotation restraining action on 5, 16, 17, and 18 is released at the same time, and when the pressing of the knob 162 is stopped, the above-described respective rotation restraining actions are simultaneously and simultaneously due to the elastic restoring force of the pin 42 itself. Since they are automatically restored, their structure and operation are extremely simple, and the operation feeling and operability of the air conditioner can be easily improved.

In addition, the rotation suppressing mechanism of the louvers 14, 15, 16, 17, 18 composed of the operating rod 41 and the pin 42 is built in the louver 16, and the rotation suppressing mechanism is provided only by the knob 162 of the louver 16.
