Description

[Detailed description of the invention] [Industrial application field] This invention is an air outlet for cooling/heating air and ventilation air provided around the instrument panel of the driver's seat, for example, for air conditioning inside a car. The present invention relates to a wind direction control device.

[Prior Art] Fig. 3 to Fig. 6 show a conventional wind direction control device of this type, in which Fig. 3 is a front view, Fig. 4 is a sectional view taken along the - line in Fig. 3, and Fig. 5 is a cross-sectional view taken along the - line in Fig. 3. Figure 3 -
6 is a cross-sectional view taken along the - line in FIG. The frames 2A, 2B are made of synthetic resin and have an opening-shaped cross section and are composed of both side walls, and the upper and lower support shafts 2b, 2b are rotated between the ceiling wall and the floor wall of the frame 1 on both sides of the machine room 1A. A pair of vertical fin groups consisting of a plurality of movably supported vertical fins 2a, one vertical fin group 2A facing the passenger seat in the interior of the automobile, and the other vertical fin group 2B facing the driver's seat. is being done. Further, the inner end portion of each vertical fin 2a is rotatably connected to a pair of connecting links 4, 4 via a connecting pin 2C. 11, 11 are integrally attached to some of the vertical fins 2a, and are used to manually swing the pair of vertical fin groups 2A, 2B; 3A, 3;
B is a pair of horizontal fin groups consisting of a plurality of horizontal fins 3a, each of which has support shafts 3b, 3b at both ends rotatably supported by the side wall of the frame 1 and the machine room wall on both sides of the machine room 1A; The inner end of each of the horizontal fins 3a is connected to a pair of connecting links 5, 5 via a connecting pin 3C.
is rotatably connected to. 6 is the machine room 1 mentioned above
This drive rod has a long hole 6a slidably inserted into an eccentric pin 10a of a drive disk 10 attached to the output shaft 9 of the drive motor 8 in A. The drive rod 6 is configured to reciprocate with a predetermined stroke in the direction of arrow X, and the drive rod 6 and the connecting links 4, 4 are configured to be frictionally connected to each other via friction clutches 7, 7.

Since this type of conventional wind direction control device is configured as described above, when the drive disk 10 is rotated at a predetermined speed by the drive motor 8, the drive disk 10
Since the eccentric pin 10a integral with the drive rod 6 reciprocates in the direction of the arrow A pair of vertical fin groups 2A and 2B are reciprocated in the left and right directions about the support shafts 2b and 2b, respectively, to automatically direct the air conditioning air or ventilation air flowing from the direction of arrow Y in the left and right direction. While converting, the air is blown out towards the driver and passenger seats inside the car. It goes without saying that the vertical fin groups 2A and 2B can be deflected in any direction by the manual handle 11 when the drive motor 8 is stopped. Further, the horizontal fin group 3 can be manually deflected in an arbitrary direction in an interlocking manner in the vertical direction.

[Problem that the invention attempts to solve]

Since the conventional wind direction control device is configured as described above, the pair of vertical fin groups 2A and 2B are always interlocked and reciprocated in the same direction, so that one of the vertical fin groups facing the driver's seat in the automobile Vertical fin group 2B
and the other vertical fin group 2A facing the passenger seat, selectively stopping the reciprocating rotation as necessary to fix the direction of air for cooling/heating or ventilation air to be blown out in a predetermined direction. There is a drawback that it cannot be done.

This invention was made with attention to this point, and the reciprocating rotation of either one of the pair of vertical fin groups is selectively stopped as necessary to control the direction of wind blowing onto the driver's or passenger's seat in the automobile. The present invention aims to provide a wind direction control device that can be fixed in a predetermined direction.

[Means for solving problems]

The wind direction control device according to this invention has manual/lock handles slidably attached to some of the vertical fins for manually swinging a plurality of groups of vertical fins, and a puller of the manual/lock handle. During operation, a stopper pin provided on the manual lock handle is fitted into a lock groove in the frame to forcibly stop the reciprocating rotation of either one of the vertical fin groups.

[Effect]

In this invention, it is possible to selectively operate one of the plurality of vertical fin groups as needed to stop the reciprocating rotation and fix the direction of the wind blowing on the driver's seat or the passenger's seat in a predetermined direction. can.

[Example of idea]

Figures 1 and 2 both show one embodiment of this invention; Figure 1 is a cross-sectional view (corresponding to Figure 4) showing a group of vertical fins of a wind direction control device according to this invention; 2A is a sectional view taken along the - line in FIG. 1, and FIG.
The same reference numerals as in FIG.

Reference numeral 12 denotes a long hole 13 into which the lower edge of a part of the vertical fins 2a of the one vertical fin group 2A is slidably fitted in the longitudinal direction, and a guide groove 14 bored in the floor wall of the frame 1. This manual lock handle is also provided with a stopper pin 16 that slidably fits into a pair of lock grooves 15, 15 provided at both ends of the guide groove 14, respectively. Although not shown, it goes without saying that the other vertical fin group 2B also has the same configuration as described above.

In the state shown by solid lines in FIGS. 1 and 2, the manual/lock handle 12 is pushed in, the stopper pin 16 of this is slidably adapted to the guide groove 14 of the frame 1, and the manual/lock handle 12 is slidably engaged with the vertical fin 2a. This shows a state in which the lock handle 12 can be rotated back and forth, and the friction clutch 7 is operated by the drive rod 6.
When the connecting link 4 is reciprocated in the left-right direction through the fins, the connecting link 4 rotates back and forth in the left-right direction using one vertical fin group 2A as a fulcrum around the support shafts 2b, 2b, and automatically changes the wind direction. It is something to do.

Next, if you want to stop the reciprocating rotation of only one vertical fin group 2A and fix the direction of the blown air in a predetermined direction, use the manual/lock handle 1.
After deflecting 2 fully to the right or left,
If you pull it out to the position shown by the one-dot chain line, this manual
The lock handle 12 moves using the vertical fins 2a as a guide, and the stopper pin 16 of the manual lock handle 12 fits into one of the lock grooves 15 from the guide groove 14.
The reciprocating rotation of A is forcibly stopped, and the wind direction can be fixed in a predetermined direction with a single touch operation. Even after the vertical fin group 2A is fixed in this way, the drive rod 6 continues to move back and forth at a predetermined stroke, but since a friction clutch 7 is interposed between the drive rod 6 and the connecting link 4, There is no possibility that the friction clutch 7 will slip, the connecting link 4 will be driven by the drive rod 6, and the vertical fin group 2A will reciprocate.

In the above-described embodiment, the case where there is a pair of vertical fin groups has been described, but it is also possible to implement the invention with one or more pairs. In addition, in the above-described embodiment, the vertical fin group is fixed manually or by pulling out the lock handle 12, but the direction of the lock grooves 15 provided at both ends of the guide groove 14 is Needless to say, this can also be done manually by pushing the lock handle 12.

[Effect of idea]

As described above, according to this invention, a desired vertical fin group out of a plurality of vertical fin groups is selectively forced to stop reciprocating rotation with a one-touch operation to fix the wind direction in a predetermined direction. Not only can the air conditioning effect be significantly improved since the wind direction control device can be adjusted, but also has the effect of being able to be implemented at low cost because its configuration is extremely simple.
