Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a wind direction changing device for an air conditioning blowing device for a vehicle.

0002

[Conventional technology]

FIG. 7 shows, for example, a conventional air conditioning blowing device shown in Japanese Utility Model Publication No. 53-51556. FIG. 2 is an exploded perspective view showing the main parts of the wind direction changing device. In the figure, 1 is the center wing of the louver. The root, 2 is a knob for rotating this, and 3 is a housing for receiving knob 2. A radial knurling 4 is formed in the recess of the ring. There is also a radial pattern on knob 2. A knurling 5 is formed. Therefore, by rotating knob 2, the louver The central blade 1 rotates, but at this time the brake is applied due to the friction between the knurls 4 and 5. The rotation angle of the louver is maintained.

0003

[Problem that the idea aims to solve]

The wind direction changing device of the above air conditioning blowout device is a rectangular frame with knurling processing. Applying it to the inside of the housing is difficult to remove from the mold in injection molding, and If the braking force does not work, the problem is that the adjustment blades will return to their original inclination due to strong wind power. there were.

0004 The present invention was devised in view of these problems, and is designed to elastically maintain the central blade shaft. We propose a wind direction changing device that holds the blade at the desired inclination using a click stop. The purpose is to provide

[0005]

[Means to solve the problem]

In order to achieve the above object, the present invention has a wind direction changing device for a vehicle air conditioning blowing device. The installation is a vehicle air conditioning blow-out device equipped with a louver for adjusting wind direction that rotates in conjunction with a knob, etc. , a spacer made of elastomer is placed at the center inside one frame of the housing. The shaft end of the central blade of the louver is elastically supported in the shaft hole of this spacer. Then insert the medium into the hemispherical recesses that are continuous on the same arc centered on the axis of the spacer. The hemispherical tip of the protrusion protruding from the end face of the center blade is configured to selectively fit into the end. be.

[0006]

[Effect]

When the knob is rotated, the rotation is elastically supported in the shaft hole made of elastomer. The shaft rotates with good feeling, but the hemispherical tip of the protrusion and the connected hemispherical recess A click stop is ensured by mating with the blade, and the inclination angle of the blade is adjusted by wind pressure The degree will not return naturally.

[0007]

【Example】

Hereinafter, embodiments of this invention will be described with reference to the drawings.

[0008] 1 to 6 show embodiments of the present invention. In the figure, 12 is approximately A louver arranged in a housing 11 consisting of a rectangular frame, each blade of the louver are connected by an interlocking link 14, are pivotally supported at the top and bottom, and are fixed to the central blade 12a. It is rotated in conjunction with operation of the operating knob 13.

[0009] FIG. 3 is an enlarged perspective view of essential parts, and FIG. 4 is a sectional view taken along the line B--B in FIG. 1. In the figure Reference numeral 15 denotes a spacer made of elastomer, which is fitted into the center inside the frame of the housing 11. It is. This fitting is done between the boss 15c on the outside of the spacer and the boss hole 1 of the housing 11. This is done by fitting with 1a. The center blade of the louver is located in the shaft hole 15a of the spacer 15. The shaft end 12b of the spacer 12a is elastically supported, and the shaft end 12b of the spacer 15 is centered on the shaft hole 15a of the spacer 15. The hemispherical recesses 15b are continuous on the same circular arc, and are protruding from the end surface of the central blade 12a. The hemispherical tip of the protruding piece 12c is selectively fitted into the protruding piece 12c. This allows you to operate the knob 13 and click when setting the louver 12 to the desired angle. The rotation angle of the louver 12, once set, will not change due to wind pressure. stomach.

0010 Although the above embodiment is applied to a vertical louver, it may also be applied to a horizontal blade louver. of the spacer Fitting is easily performed by fitting the boss and the boss hole.

[0011]

[Effect of the idea]

As described above, according to this invention, there is an elastomer at the center of the inside of one frame of the housing. A spacer made of aluminum is fitted, and the shaft end of the central blade of the louver is inserted into the shaft hole of this spacer. The two halves are elastically supported and connected on the same arc centered on the axis of the spacer. Selectively fit the hemispherical tip of the protrusion protruding from the end face of the central blade into the spherical recess. Since it is configured to rotate, the axis of the central blade is held elastically and smooth rotation is possible. The click stop has the effect of holding the blade at the desired inclination. Furthermore, according to the present invention, since the spacer is separate from the housing, it is easy to mold, and it can be formed as a single piece. It is economical because the spacer can serve as both the shaft hole and the hemispherical recess for control. It is.
