Hereinafter, the configuration of one embodiment of the present invention will be described with reference to the drawings.

In FIG. 5, reference numeral 10 denotes a wind direction adjusting device. The wind direction adjusting device 10 is for air conditioning that adjusts the direction of the wind, that is, the wind direction from an air conditioner provided in a vehicle such as an automobile. Although not shown, the wind direction adjusting device 10 is installed in an interior member of an automobile, for example, an instrument panel, a center console, an overhead console portion, a center pillar, a door trim, or the like.

Then, as shown in FIGS. 1 to 3, the wind direction adjusting device 10 includes a case body 11. The case body 11 is formed in a tubular shape, has a ventilation passage 12 through which air-conditioning air passes, and has an air outlet 13 which is a downstream end of the ventilation passage 12. Hereinafter, in order to clarify the explanation, the wind direction adjusting device 10 has the axial direction of the case body 11 as the first direction, the direction intersecting (orthogonal) with the first direction as the second direction, and the first direction and the first direction. The direction that intersects (orthogonal) with the two directions is defined as the third direction. That is, the first direction is the upstream / downstream direction of the wind passing through the ventilation passage 12. For example, in the present embodiment, the wind direction adjusting device 10 has the downstream side of the wind passing through the ventilation passage 12 which is one side of the first direction (direction of arrow D1a), that is, the occupant side as the front side and the other side of the first direction. The upstream side of the wind (in the direction of arrow D1b), that is, the back side of the ventilation path 12 when viewed from the occupants is the rear side, one side of the second direction (direction of arrow D2a) is the left side, and the other side of the second direction (arrow). It is arranged so that the D2b direction) is on the right side, one side of the third direction (arrow D3a) is on the upper side, and the other side of the third direction (arrow D3b direction) is on the lower side. The direction shall be changed as appropriate according to the installation position and installation direction of the wind direction adjusting device 10.

In the present embodiment, the case body 11 is formed so that the third direction is shorter than the second direction. That is, the case body 11 is formed in a flat shape with the second direction as the longitudinal direction and the third direction as the lateral direction. Therefore, the wind direction adjusting device 10 is formed to be thin. Therefore, the air outlet 13 is formed in a longitudinal shape in the second direction. The rear end of the case body 11 serves as a receiving port for receiving air-conditioning air from an air passage such as a duct into the ventilation passage 12. In the present embodiment, the case body 11 is integrally formed, but may be formed by combining a plurality of case members, or may be separately provided with a finisher having an open outlet 13. Good.

A downstream fin 15 which is a first fin is attached to the case body 11. The downstream fin 15 is also called a horizontal louver, a front fin, or the like. The downstream fin 15 is formed in the shape of a longitudinal plate. The downstream fin 15 is arranged so as to face the air outlet 13. Further, the downstream fin 15 has a longitudinal direction and an axial direction along the second direction, is arranged with a plate thickness direction in the third direction, and both ends thereof are rotatably supported by the case body 11. ing. Therefore, the downstream fin 15 is rotatable with respect to the case body 11 on one side and the other side in the third direction about the rotation axis. Then, the downstream fin 15 is adapted to adjust the direction of the wind blown out from the air outlet 13 through the ventilation passage 12 by rotation. That is, the downstream fin 15 can adjust the wind direction in the third direction. The downstream fins 15 may be singular or plural. In the present embodiment, three downstream fins 15 are arranged and are located apart from each other in the third direction. The plurality of downstream fins 15 are interlocked with each other by a first link (not shown) and rotate in the same direction.

Further, an upstream fin 17 which is a second fin is attached to the case body 11. The upstream fin 17 is also called a vertical louver, a rear fin, or the like. The upstream fin 17 is arranged on the other side of the first direction, that is, on the upstream side of the wind passing through the ventilation passage 12 with respect to the downstream fin 15. The upstream fin 17 is formed in a plate shape, has an axial direction along the third direction, and is arranged with a plate thickness in the second direction. The upstream fin 17 may be singular or plural. In the present embodiment, a plurality of upstream fins 17 are arranged. The plurality of upstream fins 17 are arranged at equal intervals or substantially equal intervals in the second direction. Further, both ends of the plurality of upstream fins 17 are rotatably supported by the case body 11. Therefore, the upstream fin 17 is rotatable with respect to the case body 11 in one side and the other side in the second direction about the rotation axis. That is, the upstream fin 17 is rotatable in a direction intersecting (orthogonal) with the rotation direction of the downstream fin 15. The plurality of upstream fins 17 are interlocked with each other by a second link (not shown) and rotate in the same direction. Then, the upstream fin 17 is adapted to adjust the direction of the wind blown out from the air outlet 13 through the ventilation passage 12 by rotation. That is, the upstream fin 17 can adjust the wind direction in the second direction. Further, the plurality of upstream fins 17 have a so-called fin shut structure in which the ventilation passage 12 can be closed by overlapping each other at the position where the fins 17 are maximally rotated to one side and / or the other side in the second direction. There is. That is, the plurality of upstream fins 17 are arranged with respect to the ventilation passage 12 over the entire second direction, and the total area of each is set to be larger than the cross-sectional area of the ventilation passage 12 as viewed from the first direction.

The downstream fin 15 and the upstream fin 17 are rotationally operated by the knob 20 which is the operated portion. The knob 20 is movably attached to the downstream fin 15 in a second direction that intersects the rotation direction of the downstream fin 15. That is, the knob 20 can move along the downstream fin 15 in the longitudinal direction of the downstream fin 15. In the present embodiment, the knob 20 is attached to the downstream fin 15 located at the center of the third direction among the plurality of downstream fins 15. Then, by moving the knob 20 together with the downstream fin 15 in the third direction, the knob 20 and the downstream fin 15 are integrally rotated in the third direction. Further, by sliding the knob 20 in the second direction with respect to the downstream fin 15, the upstream fin 17 rotates in the second direction.

The knob 20 includes a knob main body 22 through which the downstream fin 15 is inserted, a cover 23 attached to the knob main body 22, and a holding portion 24 attached to the knob main body 22. These may be separate from each other, or a plurality of them may be provided integrally.

The knob body 22 is formed flat along the downstream fin 15.

The cover portion 23 is a protective member that is arranged on one side of the knob main body 22 in the first direction and covers one side of the knob main body 22 in the first direction. That is, the cover portion 23 is located closest to the occupant side of the knob 20. The cover portion 23 has a non-slip function when the knob 20 is operated. Further, the cover portion 23 has a function of decoration.

The holding portion 24 is arranged on the other side of the first direction with respect to the knob main body portion 22. That is, the holding portion 24 sandwiches the knob main body portion 22 and is arranged on the side opposite to the cover portion 23. The holding portion 24 and the cover portion 23 are opposite to each other with respect to the rotation axis of the downstream fin 15. The holding portion 24 is arranged on the upstream fin 17 side of the knob 20. The holding portions 24 are provided with shaft support portions 24a and 24a at positions separated from each other in the second direction. Each shaft support portion 24a is formed with a shaft hole 24b that serves as a shaft when the knob 20 is integrally rotated with the downstream fin 15. The shaft hole 24b is formed in a round hole shape and is formed so as to penetrate the shaft support portion 24a in the second direction.

Then, the operation of the knob 20 for rotating the upstream fin 17 is transmitted to the upstream fin 17 by the link mechanism 26. The link mechanism 26 is composed of a link portion 30, a connecting portion 31, and a connected portion 32.

The link portion 30 is also called a gear link or the like, and is arranged on the upstream fin 17 side with respect to the knob 20. The link portion 30 is rotatably connected to the knob 20 in the third direction. In the present embodiment, the link portion 30 is rotatably supported in the third direction with respect to the holding portion 24 of the knob 20. The link portion 30 includes a link shaft portion 30a. The link shaft portion 30a is formed in a columnar shape, and both ends in the axial direction are rotatably supported by the shaft hole 24b of the shaft support portion 24a of the holding portion 24. Therefore, since the position of the link portion 30 on the second direction side with respect to the knob 20 is restricted, this link portion 30 is interlocked with the slide of the knob 20 to one side and the other side in the second direction with respect to the downstream fin 15. It is designed to move in the same direction as the knob 20. Further, in the link portion 30, when the shaft support portion 24a moves in conjunction with the rotation of the knob 20 and the downstream fin 15, the link shaft portion 30a rotatably supported by the shaft hole 24b moves together with the shaft support portion 24a. By doing so, the knob 20 and the downstream fin 15 rotate in the direction opposite to the rotation direction. That is, when viewed in the rotation axis direction, the rotation direction of the knob 20 and the downstream fin 15 and the rotation direction of the link portion 30 are opposite to each other.

Further, the link portion 30 includes a connecting arm portion 30b that is connected to the connecting portion 31. In the present embodiment, the connecting arm portions 30b are formed at positions near both ends of the link shaft portion 30a, respectively. The connecting arm portion 30b extends in a direction intersecting (orthogonal) with respect to the axial direction of the link shaft portion 30a. The connecting arm portion 30b extends to the other side in the first direction with respect to the link shaft portion 30a. The connecting arms 30b are parallel or substantially parallel to each other. A slit 30c is formed in the connecting arm portion 30b. The slit 30c is formed so as to penetrate the connecting arm portion 30b in the second direction. Further, the slit 30c is formed in the connecting arm portion 30b in an elongated hole shape along the longitudinal direction. That is, the slit 30c extends in a longitudinal direction in a direction intersecting (orthogonal) with respect to the axial direction of the link shaft portion 30a.

The connecting portion 31 is arranged between the link portion 30 and the upstream fin 17. The connecting portion 31 is connected to the link portion 30. In the present embodiment, the connecting portion 31 is rotatably supported in the third direction with respect to the link portion 30. That is, the connecting portion 31 includes a connecting shaft portion 31a in which both ends thereof are rotatably supported in the vertical direction in the slit 30c of the connecting arm portion 30b of the link portion 30. The connecting shaft portion 31a projects coaxially or substantially coaxially in a columnar shape from both side portions of the connecting portion 31, and is arranged along the second direction in the axial direction. Therefore, since the position of the connecting portion 31 on the second direction side with respect to the link portion 30 is restricted, the connecting portion 31 is interlocked with the slide of the knob 20 to one side and the other side in the second direction with respect to the downstream fin 15. It is designed to move in the same direction as the knob 20 integrally with the link portion 30. Further, the connecting shaft portion 31a can move (slide) in the slit 30c along the slit 30c. Therefore, when the link portion 30 rotates in conjunction with the rotation of the knob 20, the connecting shaft portion 31a slides relative to the slit 30c of the link portion 30, so that the connecting shaft portion 31a becomes the link portion 30. Does not follow. That is, the connecting portion 31 is not interlocked with the rotation of the knob 20.

Further, the connecting portion 31 includes a connecting receiving portion 31b that is connected to the connected portion 32. The connecting receiving portion 31b can have an arbitrary configuration as long as the movement of the connecting portion 31 in the second direction can be transmitted to the connected portion 32. In the present embodiment, the connecting portion 31 is a rack-shaped gear in which the connecting receiving portion 31b has a plurality of gear teeth in the second direction.

The connected portion 32 is connected to the connecting portion 31 and rotates the upstream fin 17 in conjunction with the movement of the connecting portion 31. The connected portion 32 is provided on the upstream fin 17. In the present embodiment, the connected portion 32 is integrally provided on the upstream fin 17 located at the center of the second direction among the plurality of upstream fins 17. The connected portion 32 is located on one side in the first direction with respect to the rotation axis of the upstream fin 17. That is, the connected portion 32 is located on the downstream fin 15 or the knob 20 side with respect to the upstream fin 17. Further, the connected portion 32 has a function of preventing the connecting portion 31 from rotating in the third direction due to the rotation of the link portion 30. The connected portion 32 can have an arbitrary configuration as long as it can prevent the connecting portion 31 from rotating and can transmit the movement of the connecting portion 31 in the second direction to the connected portion 32. In the present embodiment, the connected portion 32 includes a regulating portion 32a that regulates the positions of one side and the other side of the connecting portion 31 in the third direction. The regulating portion 32a is, for example, a protruding portion protruding toward one side in the first direction, that is, the connecting portion 31 side. The regulating portion 32a is formed at one position and the other side of the connecting portion 31 in the third direction, respectively. Further, the connected portion 32 includes a connected receiving portion 32b that is connected to the connecting receiving portion 31b of the connecting portion 31. The connected receiving portion 32b is formed in an uneven shape. In the present embodiment, the connecting portion 32 is a gear in which the connected receiving portion 32b is meshed with the connecting receiving portion 31b.

Next, the operation of one embodiment will be described.

In the assembled state, the wind direction adjusting device 10 has both ends of the link shaft portion 30a of the link portion 30 of the link mechanism 26 with respect to the shaft holes 24b and 24b of the shaft support portions 24a and 24a of the knob 20 attached to the downstream fin 15. The portion is rotatably supported. Further, the connecting shaft portions 31a and 31a of the connecting portion 31 are rotatably supported by the slits 30c and 30c of the connecting arm portions 30b and 30b of the link portion 30 and slidably supported along the slits 30c and 30c. Further, the connecting portion 31 is held between the regulating portions 32a and 32a of the connected portion 32, and as shown in FIG. 4, the connected receiving portion 32b of the connected portion 32 is connected to the connected receiving portion 31b of the connecting portion 31. Will be done.

Then, as shown in FIG. 2, when the occupant operates the knob 20 in the second direction, that is, along the downstream fin 15, the knob 20 slides to one side or the other side in the second direction with respect to the downstream fin 15. To do. At this time, the shaft support portions 24a and 24a of the knob 20 regulate the position of the link portion 30 in the second direction with respect to the knob 20, and the connecting arm portions 30b and 30b of the link portion 30 regulate the position of the connecting portion 31 with respect to the link portion 30. Since the positions in two directions are restricted, the link portion 30 and the connecting portion 31 slide in the same direction as the knob 20 in conjunction with the slide of the knob 20. Therefore, the connected portion 32 connected by the connected receiving portion 32b to the connecting receiving portion 31b of the connecting portion 31 is pushed in the second direction together with the upstream fin 17, so that the upstream fin 17 becomes a rotation axis. On the other hand, the downstream fin 15 side, that is, the downstream side of the wind passing through the ventilation passage 12, is swung in the second direction. Therefore, the upstream fin 17 rotates in the second direction, and the wind direction can be adjusted in the second direction. Further, at the position where the maximum swing is made to one side or the other side in the second direction, the plurality of upstream fins 17 overlap each other, thereby blocking the ventilation passage 12. In the two-dot chain line of FIG. 2, for example, the position where the upstream fin 17 is swung to the other side in the second direction to the maximum is shown, but the same action may be performed at the position where the fin 17 is swung to one side in the second direction to the maximum. ..

Further, as shown in FIG. 1, when the occupant operates the knob 20 in the third direction, that is, in the direction in which the downstream fin 15 is rotated, the knob 20 and the downstream fin 15 are integrally rotated. At this time, the link shaft portion 30a in which the link shaft portion 30a is rotatably supported by the shaft support portions 24a and 24a (shaft holes 24b and 24b) of the knob 20 is moved on the link shaft portion 30a side in conjunction with the rotation of the knob 20. Although it moves, on the connecting arm portions 30b and 30b, the connecting shaft portions 31a and 31a of the connecting portion 31 are inserted into the slits 30c and 30c, and the connecting portion 31 is in the third direction by the regulating portions 32a and 32a of the connected portion 32. Because the movement of the is restricted, the connecting portion 31 slides relative to the connecting shaft portions 31a and 31a. Therefore, the link portion 30 rotates in a direction opposite to the rotation direction of the knob 20 and the downstream fin 15 (when viewed in the second direction, when one rotates in the clockwise direction, the other rotates counterclockwise. (Rotates in the direction), and the connecting portion 31 maintains its position without being interlocked with the rotation of the link portion 30. That is, in this state, only the knob 20, the downstream fin 15, and the link portion 30 are rotated in the third direction in the ventilation passage 12, so that the case body 11 or the ventilation passage 12 is the first of these. It is sufficient if there is a dimension in the third direction that can secure the range of motion in the three directions. The two-dot chain line in FIG. 1 indicates, for example, the position where the knob 20 is swung to the other side in the third direction, but the same applies to the position where the knob 20 is swung to one side in the third direction. Further, since the connection between the link portion 30 and the connecting portion 31 is maintained by the connecting shaft portions 31a and 31a and the connecting arm portions 30b and 30b (slits 30c and 30c), the knob 20 is slid in the second direction. When this is done, the link portion 30 and the connecting portion 31 slide in the second direction integrally with the knob 20, and do not affect the operation of rotating the upstream fin 17.

As described above, according to one embodiment, the connecting portion 31 is connected to the link portion 30 that rotates in the opposite direction in conjunction with the rotation of the knob 20 and the downstream fin 15, and the connecting portion 31 is connected. It moves in the same direction in conjunction with the movement of the knob 20 in the direction along the downstream fin 15, and is not interlocked with the rotation of the knob 20, and is connected to the upstream fin 17 with respect to the connecting portion 31. By connecting the provided connected portions 32, when the knob 20 is operated to rotate together with the downstream fin 15, only the knob 20, the downstream fin 15, and the link portion 30 rotate. Since the ventilation passage 12 may be set to a size corresponding to these range of motion, it is not necessary to make the ventilation path 12 larger than necessary in the rotation direction of the downstream fin 15. That is, the size of the wind direction adjusting device 10 in the third direction can be set to the minimum, and the range of motion of the downstream fin 15 can be secured while suppressing the size of the wind direction adjusting device 10. Further, even when the knob 20 is rotated together with the downstream fin 15, the connection between the knob 20, the link portion 30, the connecting portion 31, and the connected portion 32 is maintained, so that the downstream fin 15 is rotated. Even at the position, the upstream fin 17 can be operated by operating the knob 20 so as to move it along the downstream fin 15. Therefore, it is possible to support the thin wind direction adjusting device 10. Moreover, since the swing angle of the downstream fin 15 can be set without affecting the movable range of the connecting portion 31 and the connected portion 32, the directivity of the wind is effective by freely setting the swing angle of the downstream fin 15. The air conditioning performance can be improved.

Further, a plurality of upstream fins 17 are provided, and the upstream fins 17 overlap each other at a predetermined rotation position to block the ventilation passage 12, so that the knob 20 can be moved along the downstream fins 15. The ventilation passage 12 can be blocked by the upstream fin 17 by operating the above.

Further, by setting the connecting portion 31 and the connected portion 32 to be gears that mesh with each other, when the knob 20 is operated so as to move in the second direction along the downstream fin 15, the connecting portion 31 and the connected portion 32 are connected. The meshing of the portion 32 makes it possible to reliably rotate the upstream fin 17, and the rotation angle of the upstream fin 17, that is, the wind direction control by the upstream fin 17 can be finely adjusted.

In the above embodiment, the downstream fin 15 is not limited to a plurality of fins, may be one, and may be formed in an annular shape, not limited to a plate shape.

Further, the connecting portion 31 and the connected portion 32 may be a sandwiching portion that sandwiches the shaft-shaped portion in one direction and the shaft-shaped portion in the second direction.

Further, the wind direction adjusting device 10 can also be applied to, for example, a rear seat occupant provided at the rear end of the console box.

The present invention can be suitably used as, for example, a wind direction adjusting device for air conditioning of an automobile.
