JPS585619Y2 - Wind direction plate structure for automotive air conditioners - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a wind direction plate structure in an automobile air conditioner.

As shown in Fig. 1, a wind direction plate for an air conditioner installed in an automobile's instrument panel, etc. has a louver 1 mounted in a case 3 so as to be rotatable in the vertical direction, and a louver 1 that can be rotated in the left-right direction. It is usually constructed by a combination of fins 2 which are movably mounted.

By rotating the fins 2 horizontally, the direction of the blowing air can be directed horizontally, and by rotating the louver 1 vertically, the vertical direction of the wind can be controlled. It has become.

Generally, the louver 1 and the fin 2 are held in their rotational positions by the friction between their respective rotation shafts and the bearing holes that support them.

However, when the wind direction plate is small and the number of fins 2 is small as shown in the first figure, it is quite difficult to completely hold the fins 2 in the rotational position using the friction of the rotational shaft. The fins 2 may move due to vibrations or the like.

The present invention was devised to deal with the above-mentioned problems, and the embodiments shown in FIGS. 2 and 3 will be described below.

In the present invention, in addition to the rotating shaft 2a provided integrally with the fin 2, a sliding shaft 2b is integrally formed at a position apart from the rotating shaft 2a, and the rotating shaft 2a of the fin 2 is Bearing hole 1 to fit
An arc-shaped slot 1b is formed in which the sliding shaft 2b fits into the louver 1 having a radius of 1.a and can slide therewith with a predetermined friction.

In the above configuration, when the fin 2 is rotated around the bearing hole 1a of the louver 1 to change the angle of the fin 2 as shown in FIG. 3, the sliding shaft 2b slides within the groove hole 1b with a predetermined friction. In the rotational position, the fin 2 is held in that position by the friction between the sliding shaft 2b and the end face of the slot 1b.

The holding force due to the friction of the sliding shaft 2b is quite strong because the sliding shaft 2b is located at a distance from the rotating shaft 2a, and in addition to the friction between the rotating shaft 2a and the bearing hole 1a, the fin 2 The rotational position of the rotor can be accurately maintained, and problems such as the angle being changed due to vibration or the like can be completely eliminated.

Although not shown in the figure, the plurality of fins 2 are generally configured to interlock with each other, so it is sufficient to provide the sliding shaft 2b on any one fin as shown in the figure. However, in some cases, multiple fins are provided with sliding shafts,
A groove hole 1b into which the louver 1 fits and slides may be provided on the complementary side.As described above, according to the present invention, the fin can be reliably held in the rotational position with an extremely simple structure. It is of great practical value.
