Description

[Detailed Description of the Invention] The present invention relates to an interlocking device for fins provided at an outlet for regulating air in a vehicle.

BACKGROUND ART An instrument panel or the like is provided with an air outlet for supplying adjusted air into the vehicle interior, and the air outlet is provided with fins for adjusting the airflow to the right or left, upward or downward. A plurality of such vertical or horizontal fins are provided, and each set is linked and connected so as to face in the same direction by operating an operator. A stop pin is provided, and the pins are connected to each other by a link. Conventionally, this link is molded from hard synthetic resin, so when the operating fins are operated, each fin immediately interlocks, and the operation is not controlled, and it is difficult to say that the operating feeling is necessarily good. There is a risk that it may be difficult to stop and fix the fins reliably, and furthermore, if wind pressure or the like acts in a biased manner on one fin, the entire fin moves in unison, resulting in a change in the direction of the wind.

The present invention has been made in order to improve the above-mentioned disadvantages, and its purpose is to form the link from a material such as synthetic resin that is softer than the fin material, and to form a locking hole for the link. The locking port of the link is configured to be slightly smaller than the locking pin of the fin, and the locking port of the link is press-fitted to the locking pin of the fin, and when the operating fin is operated, a time delay is caused in the interlocking of each fin due to the elastic bending action of the link. To provide an interlocking device for fins at an air outlet of a vehicle that provides a sense of moderation, improves operational feeling, secures positioning and retention, and prevents fins from drifting due to wind pressure or the like.

Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a transparent perspective view of the air outlet, FIG. 2 is a longitudinal sectional side view thereof, and FIG. 3 is an exploded perspective view of the fins and links.

A case 2 of the air outlet 1 has a frame shape penetrating in the front-rear direction, and is arranged so that the outlet 3 opens in the instrument panel of the vehicle. In the embodiment, vertical fins are shown, and fins 6 are provided between the upper and lower pieces 4 and 5 inside the case 2.
A plurality of fins are installed vertically apart from each other in the left and right direction, and the fins 6...
has a width in the front-rear direction, and support pins 7, 7... are provided protruding from the upper and lower edges of the upper and lower edges in the front-rear direction, that is, at the center in the width direction, and the support pins 7, 7... are provided in support holes 8... drilled in the upper and lower pieces 4, 5. By engaging the support pins 7, the fins 6 are pivotally supported to the case 2 so as to be swingable left and right.

Locking pins 9 are protruded from the rear ends of the upper edges 6a of the fins 6, and these pins 9 are connected to the links 1 and 1.
Pivotally connect with 0. The link 10 has a narrow width and a horizontally long rod shape, and is provided with the same number of locking holes 11 between the fins 6 in the left and right direction. An intermediate portion 10b between the base portions 10a that bulges forward and has locking holes 11 has a small width. The links 10 described above are made of a synthetic resin that is softer than the fin material and has a certain degree of elasticity, such as a thermoplastic elastomer or a firm elastic material such as a certain degree of hard rubber. The pins 9 are configured to be slightly smaller than the pins 9, and the pins 9 are press-fitted into the locking holes 11 so that there is friction between the pins 9 and the locking holes 11. The link 10 is placed on the rear part of the fins 6, and the locking holes 11 are fitted into the pins 9.

By doing this, for example, the center fin 6-
1 by grasping the knob 12 provided on the fin 6-1.
By moving the fins 6 to the right or left, the fins 6 are linked together via the link 10 so that they all face in the same direction.
During this operation, the link 10 is made of a material such as synthetic resin which is softer than the fin material, and the link 10 is made of a material such as synthetic resin which is softer than the fin material. The intermediate portion 10b bends due to its elastic bending action, so the operating load is transmitted to the locking pin of each fin with a slight time delay.
A moderate and favorable operation feeling can be obtained. After operation, the adjusted position can be held securely because the link 10 is an elastic body and the locking holes and locking pins fit together as described above, and wind pressure acts strongly on specific fins. However, this movement is absorbed by the deflection of the intermediate portion between the locking parts, and the entire fin moves in conjunction with each other, and the direction of the fin does not change.

The present invention has many advantages as mentioned above.

Although the embodiments have been described with respect to vertical fins, it should be added that the present invention can also be applied to an interlocking device for horizontal fins in which a plurality of fins are disposed horizontally in the upper and lower directions.
