Description

[Detailed Description of the Invention] The present invention relates to a wind direction adjusting device, and in particular, the present invention includes a swing operation to uniformly change the wind direction from side to side at an air outlet in a vehicle, and an operation to concentrate or diffuse the wind direction.
The present invention relates to a wind direction adjustment device that can be implemented in one drive system.

Conventionally, a wind direction adjustment device (hereinafter simply referred to as an autoregister) that automatically changes the wind direction at the outlet of an air conditioner such as a car has a plurality of blades and two connections that rotatably connect them. A swinging operation that uniformly changes the direction of the wind to the left or right by changing the direction of two groups of interlocking blades in the same direction or opposite directions, and converging the direction of the wind to one point. It is possible to selectively perform a concentrated operation or a diffused operation that spreads the wind direction to the end, depending on your preference, but in order to perform the above operation with a conventional auto register, two motors etc. are required. A drive system was required.

Each drive system requires a separate transmission mechanism capable of forward and reverse rotation, resulting in a complicated structure and an expensive device.

The present invention has been developed in view of the above circumstances, and an object of the present invention is to provide a wind direction adjustment device that allows swinging, concentration, and diffusion operations to be performed by a single drive system. It is.

In order to achieve this purpose, the present invention includes (1) a housing having an opening through which a predetermined wind is to be blown; a plurality of movably provided blades, (3) a first connecting member that connects an appropriate number of the blades to hold them at a predetermined interval, and (4) another suitable number of the blades. (5) a second connecting member that connects several sheets so as to hold them at a predetermined interval;
(6) first and second rotating disks attached to the first and second connecting members via operating members; and (6) the first rotating disk provided between the two rotating disks. (7) a rotating shaft that is fixed to the plate and is attached to the second rotating disk via an engagement mechanism that can be engaged with the second rotating disk after idle rotation by a predetermined angle; The apparatus includes a drive means capable of rotating a rotating shaft in both forward and reverse directions.

Thus, according to the present invention, two groups of blades and two connecting members that rotatably connect them can be turned in the same direction or in opposite directions. , a swinging operation that uniformly changes the wind direction from side to side, a concentration operation that gathers the wind direction at one point, and a diffusion operation that spreads the wind direction outward, all by a single drive means that can rotate in both forward and reverse directions. It has now become possible to provide a wind direction adjustment device that can be selectively implemented according to preference.

Therefore, this device has a simpler structure than conventional devices, the number of component parts is kept to a small number, it does not take up much space for installation, and it is easy to operate. .

Hereinafter, the present invention will be explained in more detail based on embodiments shown in the drawings.

First, in the auto register 2 of the automobile air conditioner shown in FIG. 1, several horizontally long blades 6 are arranged parallel to each other in an opening on one side of the front of the housing 4, which is the frame body, as is well known. The housing 4 is pivotally supported by pivot shafts 8 at both ends thereof.
Similarly, vertically long blades 10 are pivotally supported by the housing 4 at pivots 12 at both ends thereof. Note that the horizontal blades 6 may be operated in the same manner as the vertical blades 10 by a mechanism similar to that of the vertical blades 10, or a known manual adjustment mechanism may be employed, if necessary. , the following explanation will be based solely on the vertical blades 10.

Next, as shown in an enlarged perspective view in FIG. 1 at another axis 14 in the section
It is pivotally attached to a book connecting rod 16 (first connecting member) at a predetermined interval. And this connecting rod 1
6 further connects the arm 20 (actuating member) with the pin 18.
The end of the arm 20 is pivotally supported by a pin 23 that is eccentrically provided by a predetermined distance from the axis of a rotating disk 22 (first rotating member).

Similarly, the two blades 10 on the right side are pivotally connected to one connecting rod 26 (second connecting member) at a predetermined interval by another pivot 24 at the upper end portions thereof. This connecting rod 26 is further pivotally connected to an arm 30 (operating member) by a pin 28 and extended, and the end of the arm 30 is a predetermined distance from the axis of a rotating disk 32 (second rotating member). It is pivotally supported by a pin 33 that is erected eccentrically.

Furthermore, in FIG. 3 shown in an exploded perspective view, 34 is a rotating shaft, a driving gear 36 is fixed to the center thereof, and the rotating disk 22 is fixed to the lower end thereof. It is fixed at its center. On the other hand, the upper end portion of the rotary disk 32
It is adapted to be freely rotatably inserted into a hole 38 provided in the center of. The lower surface of the rotating disk 32 has two circular arcs and an angle concentric with the hole 38.
A fan-shaped locking protrusion 40 is formed with two radii forming an angle of 90 degrees, and a fan-shaped rotational protrusion 42 having the same shape as this locking protrusion 40 engages with the locking protrusion 40 on the rotating shaft 34. It is located in a position where it can be obtained.

As shown in FIG. 2, the gear 36 fixed to the rotating shaft 34 is driven in both forward and reverse directions by meshing with a pinion 46 fixed to the rotating shaft of the motor 44. 46 and the like constitute a driving means.

In the auto register 2 configured in this way, the upper end of the rotating shaft 34 is inserted into the hole 38 of the rotating disk 32, and by rotating the rotating shaft 34 clockwise, the engaging protrusion 40 and the above-mentioned Rotating protrusion 4
As shown in FIG. 4, the rotating disc 32 and the rotating shaft 34 are rotated clockwise as one body. Furthermore, in this state, the pins 23 and 33 are positioned on a straight line parallel to the axis of the rotating disk 32.

Next, if the rotation shaft 34 is rotated counterclockwise, the rotation protrusion 42 will rotate 180 degrees as shown in FIG.
The rotating disc 32 and the rotating shaft 34 are rotated counterclockwise as a unit by rotating the engaging protrusion 40 and coming into contact with the other fan-shaped side surface of the engaging protrusion 40 . In this state, the pin 23 is positioned at 180 degrees with respect to the pin 33.

That is, the pin 23 of the rotating disk 22 and the rotating disk 32
When the rotating shaft 34 is rotated in the direction of arrow A, that is, clockwise, in the arrangement shown in FIG. 4 in which the pins 33 of
As shown in Figure 7a, all the movements are the same, so the wind guided by this is shown in Figures 6b and 7.
It can be turned to the right or to the left as shown in Figure b. Therefore, if such a swinging operation is to be performed continuously to uniformly change the direction of the wind from side to side, the rotary shaft 34 may be continuously rotated clockwise by the motor 44, and the blades may be By stopping the motor 44, which is the driving source, when the inclination of 10 reaches a desired angle, the desired wind direction can be set.

On the other hand, in the arrangement shown in FIG. 5 in which there is a phase difference of 180 degrees between the rotating disks 22 and 32, when the rotating shaft 34 is rotated in the direction of arrow B, that is, in the counterclockwise direction, the blades 10 are rotated. The blades form a group of two and move in the opposite direction, as shown in Figure 8a.
When the tips of the blades 10 are narrowed, the wind direction is concentrated as shown in Figure 8b, and when the tips of the blades 10 are open as shown in Figure 9a, the wind direction is diffused as shown in Figure 9b. It becomes. Therefore, motor 4
If the rotating shaft 34 is rotated counterclockwise in the continuous operation of step 4, concentrated and diffused wind directions can of course be achieved continuously and alternately. or conversely, when it is desired to partially divert the wind direction, the motor 44 can be stopped at the desired concentrated or diffused blade angle to obtain the desired concentrated or diffused wind direction.

In this way, compared to the conventional example in which two motors are used to perform the swinging operation to uniformly change the wind direction from side to side, the concentration operation to concentrate the wind direction at one point, and the diffusion operation to spread the wind direction to the end, This device can be operated continuously and selectively at any position (angle) simply by forward and reverse rotation of a single motor, and its structure is simple and the number of components is small. They are small in number, do not take up a lot of space, and have excellent effects such as being extremely easy to operate.

In addition, in the above-mentioned embodiment, an example was shown in which the auto register 2 was provided with four blades 10, but the present invention is not limited to this in any way, and in general, five blades, six blades, etc. It may be provided with a plurality of blades.

Moreover, the rotating disks 22 and 32 do not necessarily have to be disks, but may be rotating members in the shape of arms, levers, etc. Furthermore, the engaging protrusion 40 and the rotating protrusion 42 have the same fan shape with a 90 degree angle, but instead of this, they can be engaged after idle rotation for a predetermined angle during both forward and reverse rotation. It can be an engagement mechanism. Note that this predetermined angle is
It is not limited to 180 degrees.

In addition, it goes without saying that various changes and modifications may be made to the present invention based on the knowledge of those skilled in the art without departing from the spirit of the present invention.
