Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a vehicle ventilator that can blow air by manually changing the direction of air in a vehicle such as an automobile.

(Prior art) Ventilators for vehicles are attached to instrument panels, etc., and generally the cross section of the ventilator case is often rectangular, but in recent years, from a design point of view, the air outlet has been made into an irregular shape, and the inside of the instrument panel has been A ventilator case does not necessarily have a rectangular cross section due to the various parts installed therein. In these cases, the shape of each fin is made different to match the shape of the case, and as a result, the attachment position of each fin to the case is specified. Additionally, in general, ventilators with multiple fins have an operation knob integrated into one fin to change the direction of the airflow. The fins are located at the center of the plurality of fins. Conventionally, the shafts on both sides of each fin were made to have the same diameter, and circular holes of the same diameter were formed in the side wall of the case and were fitted into the fins.

(Problems to be Solved by the Present Invention) In the above-mentioned conventional technology, each fin can be installed in any position, so there is a problem that incorrect assembly occurs, and if the hole diameters are simply made different, the torque of each fin will be different. There was a problem that the parallel rotation operation was uneven.

(Technical means for solving the problem) In order to solve the above problem, the present invention has a plurality of fins arranged in parallel, and the axis of each fin is inserted into each circular hole formed at regular intervals on both side walls of the case. In a vehicle ventilator in which the fins are fitted together and can be rotated together by connecting each fin with a connecting body, the diameter of each circular hole is different, and the diameter of both circular holes into which the shafts on both sides of each fin fit are different. The feature is that the total length is made to be approximately the same.

(Function) Since each fin can only be fitted into a circular hole with the same diameter as the shaft diameter drilled at a predetermined position, there is no possibility of incorrect assembly of each fin, and the torque of each assembled fin is approximately the same. Each fin can be rotated uniformly and smoothly in parallel.

(Example) FIGS. 1 to 3 show an example of the present invention.
1 is a case with an open rear part, and five vertical fins 2, 3, 4, 5, and 6 of different lengths are arranged in parallel on the inner front part, and both end axes have the same diameter. It is rotatably fitted into circular holes of the same diameter formed in the both side walls 1a, 1b at regular intervals in the vertical direction. 7 is a connecting body, and 8 is an operating knob.

Six vertical fins 9, 10, 11, 12, 13, and 14 according to the present invention are arranged in parallel at the inner rear part of the case 1, and the upper wall 1c of the case 1 has a right side at the maximum and a left side at the maximum. Circular holes 9a, 10a, 11 with smaller diameters in order towards the
a, 12a, 13a, 14a, case 1
The lower wall 1d has circular holes 14b, 13b, 12b, 11b, 10 with the largest diameter on the left and successively smaller diameters toward the right.
b, 9b and opposing upper and lower circular holes 9
a, 9b, 10a, 10b, 11a, 11b, 1
The total diameters of 2a, 12b, 13a, and 13b are approximately equal. and each vertical fin 9,1
The upper and lower end shafts of 0, 11, 12, and 13 have diameters that match the respective circular holes, and are rotatably fitted into each of the circular holes. 15 is a connecting body, and 16 is an operation dial.

Note that the diameter of the circular hole does not need to be changed sequentially.
As shown in the figure, the total size of the opposing circular holes may be approximately equal.

Each horizontal fin 2, 3, 4, 5, 6 has a different length, so there is no mistake in the installation position when assembling, but each vertical fin 9, 10, 11, 12, 13,
14 have the same length and different shapes depending on the cross-sectional shape of the case 1, and the mounting positions are determined.

(Effects) According to the present invention, a plurality of fins are arranged in parallel, and their respective axes are fitted into circular holes formed at regular intervals on both side walls of the case, and each fin is connected by a connecting body to form an integral body. In a rotatable vehicle ventilator, each circular hole has a different diameter, and the total length of the diameter of both circular holes into which the shafts on both sides of each fin fit are made to be approximately the same. Finn 9, 10, 11, 12,
Since the fins 13 and 14 can only be fitted into circular holes with the same diameter as the shaft diameter, there is no chance of incorrect assembly.Furthermore, the torques of the assembled fins 9, 10, 11, 12, 13, and 14 are approximately equal, so they can be assembled evenly and smoothly. It can be rotated.
