Description

Description: TECHNICAL FIELD The present invention relates to a wind direction adjusting device that adjusts a wind direction of air blown from an outlet such as a ventilator or an air conditioner of an automobile.

(Prior Art) This type of wind direction adjusting device is configured such that a plurality of louvers are arranged in parallel in an air outlet at intervals and are rotatably provided on a rotating shaft. The shaft is rotatably connected by a link, and a plurality of louvers are integrally and rotatably linked via the link so that the direction of the air blown from the outlet can be adjusted.

By the way, the wind direction adjustment device that can concentrate the wind blown out from the outlet, for example, to intensively hit or send a person far, or diffuse widely, and adjust the air volume distribution is known. is there.

As such a wind direction adjusting device, for example,
As described in Japanese Patent No. 19135, a guide groove (elongated hole) is provided in a link (movable connecting plate) to movably engage an interlocking shaft (pin) of a louver, and the link is moved in the direction in which the louver is arranged. By moving the louvers parallel to each other, the louvers are parallel and the wind blows straight forward, and the front ends of the louvers on both sides are inclined toward the center to concentrate the wind. You can set the concentration state. However, with this wind direction adjustment device,
Although the wind can be concentrated, the method and structure of adjusting the wind direction while maintaining the concentrated state by integrally rotating the louvers in the concentrated state are not shown. There was no idea about the wind direction adjustment.

Further, as described in Japanese Utility Model Publication No. 1-275050, for example, a link provided with a guide groove (guide slit) for fitting an interlocking shaft (connection pin) of a louver is moved back and forth, whereby a plurality of links are provided. Parallel state where the louvers are parallel,
By setting the concentrated state in which the front ends of the louvers on both sides are inclined toward the center and the diffusion state in which the front ends of the louvers on both sides are inclined outward, and rotating the link with the support shaft as a fulcrum, The louvers are integrally connected and rotated to adjust the wind direction. However, in this wind direction adjustment device, since the link is rotated about the support shaft and the plurality of loopers are integrally rotated, the direction of each guide groove changes, and the rotation angle of each louver varies. That is, for example, even if the link is rotated in the parallel state of the louvers, each louver does not rotate while maintaining the parallel state in an arbitrary direction, and the wind direction cannot be adjusted reliably. Moreover, even though the louver rotates only slightly, the interlocking shaft of the outer louver comes into contact with the groove end of the guide groove on the outer end where the moving amount of the link is large, and the louver cannot rotate any further. Adjustment range is narrow.

(Problems to be Solved by the Invention) As described above, in the conventional wind direction adjusting device capable of adjusting the air volume distribution, the front end of each louver is opened regardless of whether the louvers are in a parallel state, a concentrated state, or a diffused state. It was difficult to adjust the wind direction while maintaining the air flow distribution at each angle.

The present invention has been made in view of such a point, and even in a state in which the air flow distribution is adjusted by the louver, the wind direction can be easily and integrally adjusted while maintaining the adjusted air flow distribution. It is an object to provide a wind direction adjusting device.

(Means for Solving the Problems) The present invention has a rotating shaft at both ends and an interlocking shaft at one end, and is arranged at intervals at an air outlet and provided rotatably with the rotating shaft. A plurality of louvers, and a guide groove in which an interlocking shaft of each of the louvers is fitted. The linear movement in the direction in which the louvers are arranged allows the plurality of louvers to be integrally and interlocked and rotated, and the louvers are arranged in parallel. A link that adjusts the position of the interlocking shaft for each louver with each guide groove by moving in the front and rear direction perpendicular to the direction and changes the opening angle of the front end of the louver, and this link can be freely moved to a predetermined position in the front and rear direction A support that supports the louver at a predetermined position so as to be linearly movable in the louver juxtaposition direction,
Selecting means for moving the link to a predetermined position in the front-back direction.

(Operation) In the present invention, the link is moved in the front-rear direction by the selection means, whereby the position of the interlocking shaft of each louver is adjusted by the guide groove of the link to change the opening angle of the front end of the louver. The airflow distribution can be set by selecting a parallel state in which the louvers are parallel, a concentrated state in which the louver front end faces the center side, and a diffusion state in which the louver front end faces outward.

In any of the air flow distribution adjustment states such as the parallel state, the concentrated state, and the diffused state of the louvers, if the link is linearly moved in the direction in which the louvers are arranged, each louver maintains its air flow adjustment state. It is possible to adjust the wind direction by integrally rotating the wind as it is.
