In view of such drawbacks of the prior art, the present invention proposes a knob structure capable of adjusting wind directions in both vertical and horizontal directions at once by a single operation knob.

That is, the present invention comprises a plurality of vertical fins vertically arranged in the housing and a partition plate extending horizontally across the vertical fins, and each vertical fin is pivotally supported on the housing by a vertical shaft. The partition plate is provided with a damper rotatable about a horizontal axis provided at the rear edge thereof to form a horizontal fin. In a slit type register in which the direction of the air flow blown out from a slit-shaped opening provided in the front surface of the housing can be adjusted by the rotation of the fin, the horizontal shaft is attached to one end of an arm fixed to an extension of the horizontal shaft of the damper. A first drive shaft in parallel with the first drive shaft, and a second drive shaft attached to the extension of the connecting rod substantially perpendicular to the first drive shaft. The have the freedom of only motion direction 1
A single operation knob having an engagement groove and a second engagement groove having a freedom of movement only in the vertical direction with respect to the second drive shaft is provided, and the operation knob is moved in the left-right direction or the vertical direction. The wind direction adjusting device for a slit type register is characterized in that the drive shafts are moved independently of each other.

In this wind direction adjusting device, the operation knob is preferably provided in an extension region on either the left or right side of the front opening of the register, and the end of the operation knob projects from the opening.

According to this device, on the one hand, the horizontal fins can be operated independently of the vertical fins by moving the operating knobs up and down, and on the other hand, by moving the same operating knobs left and right, the horizontal fins It is possible to operate only the vertical fins without changing the position.

If this is installed in either the left or right extension area of the front opening of the register, this device can be accommodated without increasing the height of the register housing, and the slimness characteristic of the slit type register can be achieved. Without losing the appearance, it is possible to obtain the appearance that the operation knob is installed inside the front opening.

Hereinafter, the present invention will be described in more detail with reference to the preferred embodiments shown in the drawings.

〔Example〕

FIG. 1 shows a perspective view of the wind direction control device of the present invention in which the slit type resistor shown in FIG. 5 is installed in the end region in the housing of the resistor having substantially the same fin configuration. In this figure, a large number of vertical fins 3 are arranged in parallel.
Only the uppermost and lowermost pair of fins are shown. Further, in order to make the drawing easy to understand, the partition plate 2 extending in the horizontal direction between the pair of upper and lower vertical fins 3, 3 is not shown.

Similar to the conventional device shown in FIG. 5, each vertical fin 3 for adjusting the left and right wind direction is pivotally supported on the upper and lower walls of the housing 1 of the register by a shaft 4, and penetrates through the housing to move upward. A common connecting rod 5 extending in the horizontal direction is connected via an arm 7 provided at the protruding shaft end. The left and right movements of the connecting rod 5 are transmitted via the arm 7 to the shaft 4
The vertical fin 3 is rotated.

A damper 6 for adjusting the vertical wind direction is pivotally supported about a horizontal shaft 11 provided at the rear edge of a partition plate (not shown), and a pair of arms 12a is provided at an extension of this.
And 12b are fixed at predetermined intervals. The arms 12a, 12b
A first drive shaft 13 is supported at its free end in parallel with the horizontal axis. As shown in FIG. 4, upper and lower end portions 10 are formed in the extension portion of the connecting rod 5 to form the register housing 1.
Crank-type second drive shaft 15 pivotally supported on the upper and lower walls of the vehicle
Is installed vertically. As shown in the figure, the second drive shaft 15 is located near the front of the first drive shaft 13 and is arranged in a positional relationship so as to cross the first drive shaft 13.

A horizontal mounting shaft 16 is provided in front of the first and second drive shafts 13 and 15, and an operating knob 17 is provided with a boss.
It is slidably attached to the left and right along 17a. At this position, the tip of the operation knob 17 projects forward from an opening provided in the front surface of the register housing 1. On the other hand, the rear region of the operation knob 17 is cut in the horizontal direction to form the first engaging groove 18, and is further cut in the vertical direction to form the second engaging groove 19. In the first engaging groove 18, the first drive shaft 13 in the horizontal direction is provided.
Is fitted in, and both are engaged so as to be slidable in the horizontal direction. Further, the second drive shaft 15 in the vertical direction is fitted into the second engagement groove 19, and both of them are slidably engaged in the vertical direction.

As shown in FIG. 3, a sector 20 having a large number of radial notches formed on the surface thereof is installed at the tip of the horizontal shaft 11 projecting outward from the side wall of the register housing 1. A leaf spring 21 fixed to the spring exerts an elastic force, and a protrusion provided on the spring engages in the notch.

Next, the operation of the wind direction adjusting device having the above configuration will be described.

In order to deflect the vertical fins 3, the operation knob 17 may be slid rightward or leftward along the mounting shaft 16 by a desired distance. By this movement, the second drive shaft 15 fitted in the second engaging groove 19 also rotates rightward or leftward about the fulcrum 10, and the vertical fin 3 is moved through the connecting rod 5, the arm 7 and the shaft 4. Rotate by the desired angle.

On the other hand, in order to deflect the damper 6, it is sufficient to rotate the operation knob 17 about the mounting shaft 16 in the vertical direction by a desired angle. By this movement, the first drive shaft 13 fitted in the first engaging groove 18 is rotated about the horizontal shaft 11 by a desired angle, and the horizontal shaft 11 is also rotated accordingly and the damper 6 is rotated. Is rotated up or down. When the above-mentioned operation knob 17 is operated, the drive shaft, which is not the object of movement, slides only along the engaging groove into which it is fitted, and is not affected at all.

Further, since the sector 20 and the leaf spring 21 are engaged with each other, when the damper 6 is operated, a certain click feeling can be obtained due to the resistance when the projection gets over the notch. However, if the click feeling is not so important, this may be omitted and the operation feeling may be obtained only by the resistance of the rotating portion.

It is desirable that the cross-sectional shape of the extension of the horizontal shaft 11 and the holes of the arms 12a and 12b that support the horizontal shaft 11 are non-circular as shown in the exploded perspective view of FIG.
Further, it is desirable that the operation end of the operation knob 17 is provided with unevenness to prevent slipping.

Further, the second drive shaft 15 is fixed to the connecting rod 5 in a floating state without being pivotally supported by the upper and lower walls of the register housing 1, so that the lateral movement of the operating knob 17 is directly transmitted to the connecting rod 5. You may

The operation direction of the operation knob 17 may be a vertical slide type or a horizontal rotary type instead of a horizontal slide type or a vertical rotary type as in the example shown in the figure, and may be a slide type in both directions or a 360 ° rotary type like a universal joint. Formula type can also be adopted.

[Effect of device]
