Description

  The present invention relates to an air-conditioning register that changes the direction of air-conditioning air sent from an air-conditioning apparatus and blown into a room.

  An air conditioning register for changing the direction of air conditioning air sent from the air conditioner and blown into the passenger compartment is incorporated in the instrument panel of the vehicle. As one form of this air-conditioning register, various types have been conventionally considered in which the dimension is greatly different between the vertical direction and the horizontal direction, for example, a thin air-conditioning register in which the horizontal dimension is larger than the vertical dimension. For example, a thin air-conditioning register described in Patent Document 1 includes a case, a pair of auxiliary fins, a main fin, and an interlocking mechanism.

  The case has a rectangular tube shape with a low height, and has an internal space as a ventilation path for air for air conditioning. The pair of auxiliary fins extend in the vehicle width direction at locations close to the upper and lower wall portions in the ventilation path. Both auxiliary fins are supported to be tiltable in the vertical direction with respect to the left and right wall portions of the case. The main fin extends in the vehicle width direction between the two auxiliary fins, and is supported to be tiltable in the vertical direction with respect to the left and right wall portions.

  The interlocking mechanism makes both auxiliary fins parallel to the upper and lower wall portions when the main fin is parallel to the upper and lower wall portions. In addition, when the main fin is tilted from the above state, the interlocking mechanism has upper and lower wall portions so that both of the auxiliary fins are pushed toward the inside of the ventilation path with the tilt. Tilt against.

  Therefore, when the main fin is tilted from a state parallel to the upper and lower wall portions, the air-conditioning air flowing through the intermediate portion in the vertical direction can be changed in direction by flowing along the main fin. Air conditioning air flowing near the upper wall of the case flows along the upper auxiliary fin, and air conditioning air flowing near the lower wall flows along the lower auxiliary fin. The direction can be changed to the inside of the air passage. These air-conditioning airs are collected around the main fin, and can be turned by flowing along the main fin. As a result, the air for air conditioning is blown from the case in the direction toward the main fin, and the directivity of the air for air conditioning when the main fin is inclined is improved.

JP 2010-105507 A

  By the way, in the air-conditioning register described in Patent Document 1 above, the upper and lower auxiliary fins are tilted in conjunction with the main fin, and the downstream end is inclined with respect to the upper and lower walls so as to protrude toward the inside of the ventilation path. When further thinning is attempted, the inclined main fin and the auxiliary fin near the upstream end of the main fin may interfere with each other. Therefore, there is a problem that there is a limit in reducing the thickness.

  The present invention has been made in view of such circumstances, and the object thereof is for air conditioning that can suppress interference with the auxiliary fin when the main fin is inclined and can be further reduced in thickness. To provide a register.

  In order to achieve the above object, the invention according to claim 1 is a pair of first wall portions facing each other in the first direction and a pair of first wall portions facing each other in a second direction orthogonal to the first direction. The two wall portions are formed in a cylindrical shape longer in the first direction than the second direction, and have a case having an internal space as a ventilation path for air for air conditioning, and approach the second wall section in the ventilation path The pair of auxiliary fins that extend in the first direction at the locations and are supported by the support shaft so as to be tiltable in the second direction with respect to the first wall portion, and in the first direction between the two auxiliary fins A main fin that extends and is supported by the support shaft so as to be tiltable in the second direction with respect to the first wall portion, and is provided between the main fin and the auxiliary fins, and the main fin is provided on the second wall. When the two parallel fins are in parallel with each other, the two auxiliary fins are When the main fin is tilted from the state, the auxiliary fin on the side close to the upstream end of the main fin is in a state parallel to the second wall portion and far from the main fin. A gist is that the auxiliary fin on the side is provided with an interlocking mechanism that inclines with respect to the second wall portion so that the downstream end of the auxiliary fin projects toward the inside of the ventilation path.

According to said structure, when a main fin is made into the state parallel to the 2nd wall part, it is made into the state parallel to the 2nd wall part in the location where each auxiliary fin approached the 2nd wall part. The
From the above state, when the main fin is tilted in the second direction with the support shaft as a fulcrum, the auxiliary fin close to the upstream end of the main fin is maintained in a state parallel to the second wall portion. Further, the auxiliary fin on the side far from the upstream end of the main fin is tilted with the support shaft as a fulcrum, and the downstream end of the auxiliary fin is tilted with respect to the second wall portion so as to protrude toward the inside of the ventilation path. .

  Therefore, in the ventilation path of the case, the air-conditioning air flowing through the intermediate portion in the second direction can be changed in direction by flowing along the main fin. Further, the air-conditioning air that flows in the vicinity of the second wall portion on the side far from the upstream end of the main fin changes its direction to the inside of the air passage by flowing along the auxiliary fin on the side far from the upstream end. The air for air conditioning is collected around the main fin, and the direction is changed by flowing along the main fin. Accordingly, the air-conditioning air is blown out from the case in the direction toward the main fin, and the directivity of the air-conditioning air is improved.

  Further, as described above, when the main fin is tilted, the auxiliary fin on the side close to the upstream end of the main fin does not tilt and maintains a state parallel to the second wall portion. Therefore, even if the upstream end of the main fin is brought close to the auxiliary fin on the side close to the upstream end, interference between the two is less likely to occur. Therefore, by arranging the auxiliary fin and the second wall near the upstream end of the main fin at a location close to the main fin, it is possible to reduce the size of the air conditioning register in the second direction.

  The invention according to claim 2 is the invention according to claim 1, wherein the interlocking mechanism is an engagement portion provided in each of the auxiliary fins and a member that tilts in conjunction with the main fin, While having a pair of to-be-engaged part with which the said engaging part for every auxiliary fin is each engaged, each to-be-engaged part is by the transmission area | region which transmits the said tilt to the said auxiliary fin, and the non-transmission area | region which does not transmit A transmission member configured, and when the main fin is in a state parallel to the second wall portion, the engaging portions are positioned at a boundary between the transmission region and the non-transmission region. When both the auxiliary fins are parallel to the second wall portion and the main fin is tilted from the state, the engaging portion of the auxiliary fin on the side close to the upstream end of the main fin is Non-communication area By placing the auxiliary fin in a state parallel to the second wall portion, the engaging portion of the auxiliary fin on the far side is positioned in the transmission region, so that the auxiliary fin is The gist is that the downstream end is inclined with respect to the second wall portion so as to protrude toward the inside of the ventilation path.

  According to said structure, when a main fin is made into the state parallel to the 2nd wall part, the engaging part for every auxiliary | assistant fin becomes the boundary of the transmission area | region and non-transmission area | region in the to-be-engaged part of a transmission member. It is located and it is made into the state parallel to the 2nd wall part in the location where the auxiliary fin approached the 2nd wall part.

  From the above state, when the main fin is tilted in the second direction around the support shaft, the tilt is transmitted to the transmission member, and the transmission member is displaced. The pair of engaged portions provided on the transmission member are also displaced. At this time, the engaging portion of the auxiliary fin on the side close to the upstream end of the main fin is located in the non-transmitting region, and the displacement of the transmitting member is not transmitted to the engaging portion and the auxiliary fin. Therefore, the auxiliary fin is maintained in a state parallel to the second wall portion.

  The engaging portion of the auxiliary fin on the side far from the upstream end of the main fin is located in the transmission region, and the displacement of the transmitting member is transmitted to the engaging portion and the auxiliary fin. Therefore, the auxiliary fin is tilted with the support shaft as a fulcrum, and is tilted with respect to the second wall portion so that the downstream end of the auxiliary fin protrudes toward the inside of the ventilation path.

  According to a third aspect of the present invention, in the second aspect of the present invention, when the main fin is inclined with respect to the second wall portion at a maximum angle that can be taken, the side farther from the upstream end of the main fin. The auxiliary fin is inclined toward the main fin.

  According to said structure, when the main fin is made to incline with respect to the 2nd wall part at the maximum angle which can be taken, the auxiliary fin of the side far from the upstream end of a main fin is made to incline toward the main fin. Therefore, in the ventilation path, the air for air conditioning flowing between the main fin and the second wall portion far from the upstream end flows along the auxiliary fin far from the upstream end, so that the main fin side Is turned around and collected around the main fin.

  According to a fourth aspect of the present invention, in the third aspect of the present invention, the auxiliary fin on the side farther from the upstream end of the main fin in the state inclined at the maximum angle is the air flow path in the main fin. It is made to incline toward the location used as the center part about the distribution direction of the air for air conditioning in the above.

  According to said structure, when the main fin is made to incline with respect to a 2nd wall part at the maximum angle which can be taken, the auxiliary fin of the side far from the upstream end of a main fin is for air conditioning in a ventilation path in a main fin. It inclines toward the location used as the center part about the distribution direction of air. Therefore, in the ventilation path, air-conditioning air flowing along the second wall portion far from the upstream end of the main fin flows along the auxiliary fin far from the upstream end, so that the central portion of the main fin The direction can be changed to the side. The air for air conditioning hits the upstream side of the central portion of the main fin, and the direction of the air is changed by flowing along the main fin.

  The invention according to claim 5 is the invention according to any one of claims 2 to 4, wherein the interlocking mechanism includes a mechanism for transmitting the tilt of the main fin to the transmission member, An arm extending from the support shaft of the main fin in a direction orthogonal to the support shaft, and a transmission provided at a position deviated from the support shaft of the arm and engaged with a long hole formed in the transmission member. The gist is to provide a shaft.

  According to the above configuration, when the main fin is tilted in the second direction with the support shaft as a fulcrum, the transmission shaft turns around the support shaft. A force in the second direction is applied to the transmission member from the transmission shaft, and the transmission member is displaced.

  The invention according to claim 6 is the invention according to any one of claims 2 to 5, wherein an arm extends from the support shaft for each auxiliary fin in a direction perpendicular to the support shaft. The gist of the present invention is that a transmission shaft is provided as the engaging portion at a location deviated from the support shaft of the arm.

  According to said structure, in the arm extended from the spindle for every auxiliary fin, the transmission shaft provided in the location biased from the spindle functions as an engaging part for every auxiliary fin. Therefore, when the transmission member is displaced with the tilting of the main fin and the pair of engaged portions are displaced, the position of the transmission shaft in the engaged portion is changed. When the transmission shaft is positioned in the transmission region of the engaged portion, the displacement of the transmission member is transmitted to the transmission shaft through the engaged portion. By this transmission, the arm is tilted in the second direction with the auxiliary shaft as a fulcrum with the auxiliary fin. Further, when the transmission shaft is positioned in the non-transmission region of the engaged portion, the displacement of the transmission member is not transmitted to the transmission shaft through the engaged portion, and the arm and the auxiliary fin do not tilt with the support shaft as a fulcrum.

  The invention according to claim 7 is the invention according to any one of claims 2 to 6, wherein the transmission member is supported to be tiltable in the second direction by an axis with respect to the first wall portion. The gist of the invention is that the engaged portion is constituted by a cam member provided with a cam hole or a cam groove.

  According to the above configuration, the cam member supported by the shaft with respect to the first wall portion functions as a transmission member, and the pair of cam holes or the pair of cam grooves provided in the cam member functions as the engaged portion. To do. Therefore, when the main fin is tilted in the second direction with the support shaft as a fulcrum, the tilt is transmitted to the cam member, and the cam member is tilted in the same direction with the shaft as a fulcrum, and a pair of cam holes or a pair of cams The groove turns around the axis. The position of the engaging portion for each auxiliary fin in the cam hole or cam groove changes. When the engaging portion is positioned in the transmission region of the cam hole or the cam groove, the tilt of the cam member is transmitted to the engaging portion, and the auxiliary fin tilts with the support shaft as a fulcrum. When the engaging part is located in the non-transmitting region, the tilting of the cam member is not transmitted to the engaging part. The engaging portion does not move, and the auxiliary fin does not tilt.

  The invention according to claim 8 is the invention according to any one of claims 1 to 7, wherein an operation knob is fitted on the main fin so as to be slidable in the first direction. In a state where the main fin is inclined at the maximum angle that can be taken with respect to the second wall portion, a part of the operation knob is located on the downstream side of the auxiliary fin on the side far from the upstream end of the main fin. This is the gist.

  According to said structure, when the main fin is made to incline with respect to the 2nd wall part at the maximum angle which can be taken, a part of operation knob is located in the downstream of the auxiliary fin in the side far from the upstream end of a main fin. To do.

  Therefore, even if the air for air conditioning tries to flow parallel to the second wall portion between the main fin and the auxiliary fin on the side far from the upstream end of the main fin, the air for air conditioning is downstream of the auxiliary fin. It hits the operation knob located on the side. The direction of the air for air conditioning is changed by the operation knob in the direction toward the main fin. Therefore, the directivity of air for air conditioning when the main fin is inclined at the maximum angle that can be taken is improved.

  According to the air-conditioning register of the present invention, it is possible to suppress the interference with the auxiliary fin when the main fin is inclined, and to further reduce the thickness.

  One support shaft 36 of the auxiliary fin 35 protrudes outward in the first direction (vehicle width direction) from the first wall portion 21. A long arm 64 is formed at the outer end of the support shaft 36, starting from the support shaft 36 and extending in a direction perpendicular to the support shaft 36. When the auxiliary fin 35 is in a state parallel to the second wall portion 22, the arm 64 is inclined so as to be slightly higher toward the downstream side (see FIG. 12). A transmission shaft 65 as an engaging portion protrudes outward in the first direction (vehicle width direction) from the downstream end, which is a position deviated from the support shaft 36 of the arm 64.

  On a shaft 28 provided on one first wall portion 21, a plate-like cam member 66 can be tilted in the second direction (vertical direction) as a transmission member that is displaced as the main fin 31 tilts. It is supported by.

  In the cam member 66, one long hole 67 and a pair of upper and lower cam holes 68 and 69 serving as engaged portions are formed in a portion downstream of the shaft 28. The long hole 67 is located between the cam holes 68 and 69 in the second direction (vertical direction). The long hole 67 becomes parallel to the second wall portion 22 when the main fin 31 becomes parallel to the second wall portion 22.

  The upper cam hole 68 is configured by a combination of the first hole portion 68A and the second hole portion 68B. The first hole 68 </ b> A constitutes a non-transmission region in which the displacement (tilt) of the cam member 66 accompanying the tilt of the main fin 31 is not transmitted to the upper auxiliary fin 33, and has an arc shape centered on the shaft 28. Is formed. The second hole 68B constitutes a transmission region that transmits the displacement (tilt) of the cam member 66 to the upper auxiliary fin 33 through the transmission shaft 63, the arm 62, and the support shaft 34, and has a linear shape. ing. The second hole 68B is connected to the upstream end of the first hole 68A at the downstream end thereof.

  The lower cam hole 69 is configured by a combination of the first hole 69A and the second hole 69B. The first hole 69A constitutes a non-transmission area in which the displacement (tilt) of the cam member 66 accompanying the tilt of the main fin 31 is not transmitted to the lower auxiliary fin 35, and is a circle centered on the shaft 28. It is formed in an arc shape. The second hole 69B constitutes a transmission region that transmits the displacement (tilting) of the cam member 66 to the lower auxiliary fin 35 through the transmission shaft 65, the arm 64, and the support shaft 36, and has a linear shape. There is no. The second hole 69B is connected to the upstream end of the first hole 69A at the downstream end thereof.

  The transmission shaft 61 of the main fin 31 is movably engaged in the long hole 67. The transmission shaft 61 is positioned at the upstream end of the long hole 67 when the main fin 31 is in a state parallel to the second wall portion 22 (see FIGS. 7 and 8). The transmission shaft 61 is located at the downstream end of the long hole 67 or in the vicinity thereof when the main fin 31 is inclined with respect to the second wall portion 22 (see FIGS. 10 and 12). The long hole 67, the arm 59 and the transmission shaft 61 described above constitute a transmission mechanism 90 that transmits the tilt of the main fin 31 to the cam member 66.

  Note that 58 in FIG. 7 is in contact with the arm 59 when the main fin 31 is inclined at the maximum angle that can be taken with respect to the second wall portion 22, and the arm 59 and further the tilt of the main fin 31 are tilted. It is a pair of upper and lower stoppers that regulate Both stoppers 58 are provided above and below the arm 59 on the outer wall surface of the first wall portion 21, and are inclined with respect to the second wall portion 22 so that the distance between the stoppers 58 increases toward the upstream side. That is, the upper stopper 58 is inclined so as to become higher toward the upstream side, and the lower stopper 58 is inclined so as to become lower toward the upstream side.

  Further, 86 in FIG. 7 is an arc-shaped locking hole provided in the cam member 66 and centering on the shaft 28, and 87 is provided in the first wall portion 21 and is formed in the locking hole 86. It is the latching protrusion inserted. The locking projection 87 is locked to the cam member 66 at the claw portion provided at the outer end thereof, and restricts the movement (rattle) of the cam member 66 in the first direction (vehicle width direction). ing.

The transmission shaft 63 of the auxiliary fin 33 is movably engaged in the cam hole 68 and the transmission shaft 65 of the auxiliary fin 35 is movably engaged in the cam hole 69.
The transmission shafts 63 and 65 are engaged with the cam holes 68 and 69 so as to satisfy the following conditions.

  (I) As shown in FIGS. 7 and 8, in the state where the main fin 31 is parallel to the second wall portion 22, the transmission shaft 63 has the first hole portion 68 </ b> A (non-transmission region) and the second hole. The transmission shaft 65 is located at a boundary portion between the first hole 69A (non-transmission region) and the second hole 69B (transmission region).

In this state, the auxiliary fins 33 and 35 are parallel to the second wall portion 22.
(Ii) As shown in FIGS. 9 and 10, the transmission shaft 63 is positioned in the first hole 68 </ b> A in a state where the main fin 31 is inclined with respect to the second wall portion 22 so as to become lower toward the downstream side, The transmission shaft 65 is located in the second hole 69B.

  In this state, the upper auxiliary fin 33, which is an auxiliary fin closer to the upstream end of the main fin 31, is in a state parallel to the second wall portion 22. Further, the lower auxiliary fin 35, which is the auxiliary fin far from the upstream end of the main fin 31, is inclined with respect to the second wall portion 22 so as to be higher toward the downstream side, and the downstream end is the ventilation path. 20 to the inside.

  (Iii) As shown in FIGS. 11 and 12, in a state where the main fin 31 is inclined with respect to the second wall portion 22 so as to be higher toward the downstream side, the transmission shaft 63 is located in the second hole portion 68B, The transmission shaft 65 is located in the first hole 69A.

  In this state, the upper auxiliary fin 33 that is the auxiliary fin farther from the upstream end of the main fin 31 is inclined with respect to the second wall portion 22 so as to become lower toward the downstream side, and the downstream end is ventilated. It rushes to the inside of the road 20. The lower auxiliary fin 35, which is an auxiliary fin closer to the upstream end of the main fin 31, is in a state parallel to the second wall portion 22.

  Furthermore, in a state where the main fin 31 is inclined at the maximum angle that can be taken, the auxiliary fins 35 and 33 on the side far from the upstream end of the main fin 31 are inclined toward the main fin 31. In the present embodiment, the auxiliary fins 35 and 33 are set so as to be inclined toward the central portion of the main fin 31 with respect to the flow direction of the air-conditioning air A in the ventilation path 20.

  In addition, as shown in FIGS. 9 and 11, in a state where the main fin 31 is inclined at the maximum angle that can be taken, a part (downstream end) of the operation knob 40 is far from the upstream end of the main fin 31. It is set so as to be located downstream of the auxiliary fins 35 and 33 on the side. In other words, when the air conditioning register is viewed from the downstream side toward the upstream side, a part of the operation knob 40 is overlapped with the downstream ends of the auxiliary fins 35 and 33 far from the upstream end of the main fin 31. I'm getting tired. 9 and 11 indicates an overlapping portion between the operation knob 40 and the auxiliary fins 35 and 33.

<Shut damper 70>
As shown in FIGS. 4 to 6, the shut damper 70 opens and closes the ventilation path 20 on the upstream side of the upstream fin group in the case 10. The shut damper 70 corresponds to a surface orthogonal to the ventilation path 20, and has a main body 71 that has a rectangular plate shape elongated in the first direction (vehicle width direction) rather than the second direction (vertical direction), and the main body 71 And a seal portion 72 attached to the periphery of the.

  From both end faces of the main body 71 in the first direction (vehicle width direction), the support shaft 73 protrudes outward in the same direction (see FIG. 3). The shut damper 70 is supported on the first wall portion 21 by the bearing portion 29 on both the support shafts 73, and can be tilted in the second direction (vertical direction) between the open position and the closed position. In the open position, the shut damper 70 is in a state parallel to the second wall portion 22 at the center portion between the two second wall portions 22 to greatly open the ventilation path 20. In the closed position, the shut damper 70 is inclined with respect to both the second wall portions 22, contacts the inner wall surfaces of the first wall portion 21 and the second wall portion 22 at the seal portion 72, and closes the ventilation path 20.

<Damper drive mechanism 80>
As shown in FIGS. 1, 3, and 6, the damper drive mechanism 80 is a mechanism for tilting the shut damper 70 to open and close the ventilation path 20, sandwiching the case 10, and in a first direction (vehicle width direction) ) Is provided on the side opposite to the interlocking mechanism 60. The damper drive mechanism 80 includes an operation dial 81 and a rotation transmission unit 82. The operation dial 81 is supported with respect to the case 10 so as to be rotatable in the second direction (vertical direction). A part of the operation dial 81 is exposed to the downstream side through the window portion 13 </ b> A of the bezel 13.

  The rotation transmitting unit 82 is for transmitting the rotation of the operation dial 81 to the shut damper 70. The rotation transmission part 82 is configured by a link mechanism, a gear mechanism, and the like, and is located outward in the first direction (vehicle width direction) from the first wall part 21, and includes the operation dial 81 and the shut damper 70. It is provided between the support shaft 73.

As described above, the air-conditioning register of this embodiment is configured. Next, the operation of this air conditioning register will be described.
The two-dot chain line in FIGS. 4 and 5 shows a state when the shut damper 70 is in the closed position. In this state, the ventilation path 20 is blocked by the shut damper 70. The flow of the air conditioning air A in the ventilation path 20 is blocked, and the blowing of the air conditioning air A from the air outlet 14 is stopped.

  On the other hand, the solid lines in FIGS. 4 and 5 show the state when the shut damper 70 is in the open position. In this state, the ventilation path 20 is fully opened, and the air-conditioning air A flows separately on the upper side and the lower side of the shut damper 70. The air-conditioning air A that has passed through the shut damper 70 flows along the upstream fin group and the downstream fin group, and then blows out from the air outlet 14.

  Switching of the shut damper 70 from the closed position to the open position, and switching from the open position to the closed position is performed through a turning operation of the operation dial 81. When the operation dial 81 is rotated by an occupant, the rotation is transmitted to the shut damper 70 via the damper drive mechanism 80, and the shut damper 70 is tilted.

In the following description, it is assumed that the shut damper 70 is in the open position. Further, in FIG. 8, FIG. 10, and FIG. 12, illustration of details is omitted.
4 to 6 show an air-conditioning register in which the main fins 31 are parallel to the second wall portion 22.

  In this air conditioning register, as shown in FIGS. 7 and 8, the transmission shaft 61 is positioned at the upstream end of the long hole 67, and the long hole 67 and the cam member 66 are parallel to the second wall portion 22. Become. The transmission shaft 63 of the upper auxiliary fin 33 engages with the cam hole 68 at the boundary between the first hole 68A and the second hole 68B. The arm 62 is inclined so as to be slightly lower toward the downstream side, and the upper auxiliary fin 33 is parallel to the second wall portion 22 and stored in the upper storage recess 24.

  Further, the transmission shaft 65 of the lower auxiliary fin 35 engages with the cam hole 69 at the boundary portion between the first hole 69A and the second hole 69B. The arm 64 is inclined so as to be slightly higher toward the downstream side, and the auxiliary fin 35 is parallel to the second wall portion 22 and is stored in the lower storage recess 24.

  Therefore, as shown by the two-dot chain arrows in FIGS. 4 and 5, the air-conditioning air A that has passed through the shut damper 70 receives almost no resistance from the auxiliary fins 33, 35, and the main fin 31, auxiliary fin It flows with little pressure loss along the 33 and 35 and the second wall portion 22.

  When a downward force is applied to the operation knob 40 from the above state, the main fin 31 is tilted counterclockwise around the support shaft 32 as shown in FIGS. 9 and 10. With this tilting, the arm 59 tilts in the same direction with the support shaft 32 as a fulcrum. The transmission shaft 61 turns around the support shaft 32 in the counterclockwise direction. An upward force is applied to the cam member 66 from the transmission shaft 61, and the cam member 66 tilts clockwise with the shaft 28 as a fulcrum. Along with this, both cam holes 68 and 69 also turn around the shaft 28 in the same direction, and the engagement positions of the transmission shafts 63 and 65 in the cam holes 68 and 69 change.

  The engagement position of the transmission shaft 63 at the cam hole 68 changes from the boundary portion between the first hole portion 68A and the second hole portion 68B to the side closer to the downstream end of the first hole portion 68A. Therefore, the tilt of the main fin 31 is not transmitted to the transmission shaft 63 through the cam hole 68, and the arm 62 maintains a tilted state that becomes slightly lower toward the downstream side. As a result, the auxiliary fin 33 on the side close to the upstream end of the main fin 31 is maintained in a state parallel to the second wall portion 22.

Note that the transmission shaft 63 reaches the downstream end of the first hole 68A when the main fin 31 is inclined at the maximum angle downward.
In contrast, the engagement position of the transmission shaft 65 at the cam hole 69 changes from the boundary portion between the first hole portion 69A and the second hole portion 69B to the side closer to the upstream end of the second hole portion 69B. Therefore, the tilt of the cam member 66 is transmitted to the transmission shaft 65 through the cam hole 69. The transmission shaft 65 receives upward force from the wall surface of the second hole 69B and moves upward, and the arm 64 is tilted clockwise with the support shaft 36 as a fulcrum. The lower auxiliary fin 35 connected to the arm 64 via the support shaft 36 is tilted in the same direction with the support shaft 36 as a fulcrum.

  When the main fin 31 is tilted downward by the maximum angle, the transmission shaft 65 reaches the upstream end of the second hole 69B. At this time, the arm 64 is in an inclined state that becomes higher toward the downstream side. As a result, the auxiliary fin 35 on the side farther from the upstream end of the main fin 31 is inclined toward the center of the main fin 31 in the ventilation direction of the air-conditioning air A, and the downstream end is directed to the inside of the ventilation path 20. A big rush.

  Therefore, the air-conditioning air A that flows through the intermediate portion in the second direction (vertical direction) can be changed in direction by flowing along the main fin 31. Further, the air-conditioning air A flowing along the lower second wall portion 22 is changed to the inner side of the ventilation passage 20 by the lower auxiliary fins 35 and collected around the main fins 31. The air-conditioning air A flows along the main fin 31 inclined so as to become lower toward the downstream side, and blows off obliquely downward from the outlet 14.

  In particular, in the present embodiment, the air conditioning air A flows along the auxiliary fins 35, whereby the direction of the main fin 31 is changed to the central portion side with respect to the flow direction of the air conditioning air A in the ventilation path 20. The air-conditioning air A hits the upstream portion of the main fin 31 with respect to the central portion and is changed in direction by flowing along the main fin 31.

  At this time, the upstream end of the inclined main fin 31 is close to the upper auxiliary fin 33, and the gap between the two is slight. Therefore, there is little air-conditioning air A that flows straight through this gap.

  Further, even if the air-conditioning air A tries to flow between the main fin 31 and the lower auxiliary fin 35 in a state parallel to the second wall portion 22, the air-conditioning air A is downstream of the auxiliary fin 35. It hits the operation knob 40 located on the side. The air-conditioning air A flows along the operation knob 40 and flows in a direction (obliquely downward) toward the main fin 31.

  When returning the main fin 31 from the above state to a state parallel to the second wall portion 22, an upward force is applied to the operation knob 40. By this force, the main fin 31 is tilted clockwise with the arm 59 and the support shaft 32 as a fulcrum. The transmission shaft 61 pivots clockwise around the support shaft 32, the cam member 66 tilts counterclockwise about the shaft 28, and both cam holes 68 and 69 pivot around the shaft 28 in the same direction. To do.

  The engagement position of the transmission shaft 63 at the cam hole 68 changes from the downstream end of the first hole 68A toward the side closer to the boundary with the second hole 68B. Therefore, the tilt of the main fin 31 is not transmitted to the transmission shaft 63 through the cam hole 68. The transmission shaft 63 does not move, and the inclined state where the arm 62 is slightly lowered toward the downstream side is maintained. As a result, the auxiliary fin 33 continues to be stored in the upper storage recess 24 in a state parallel to the second wall portion 22.

  On the other hand, the engagement position of the transmission shaft 65 at the cam hole 69 changes from the upstream end of the second hole 69B toward the side closer to the boundary with the first hole 69A. Therefore, the tilt of the cam member 66 is transmitted to the transmission shaft 65 through the cam hole 69, and the arm 64 is tilted counterclockwise with the auxiliary shaft 35 and the support shaft 36 as a fulcrum. When the transmission shaft 65 moves along the second hole 69B to the boundary with the first hole 69A, as shown in FIG. 8, the arm 64 is inclined so as to be slightly higher toward the downstream side. As shown in FIGS. 4 and 5, the auxiliary fin 35 is parallel to the second wall portion 22 and stored in the lower storage recess 24.

  When an upward force is applied to the operation knob 40 on the main fin 31 that is parallel to the second wall portion 22, as shown in FIGS. 11 and 12, the main fin 31 and Both auxiliary fins 33 and 35 perform the reverse operation.

  The tilt of the main fin 31 is not transmitted to the transmission shaft 65 through the cam hole 69, and the arm 64 is maintained in a tilted state in which the arm 64 is slightly raised toward the downstream side, and the auxiliary fin 35 is in a state parallel to the second wall portion 22. Maintained. In contrast, the tilt of the main fin 31 is transmitted to the transmission shaft 63 through the cam hole 68, and the arm 62 is tilted counterclockwise with the auxiliary shaft 33 and the support shaft 34 as a fulcrum. In the main fin 31, the auxiliary fin 33 is greatly pushed toward the inside of the ventilation path 20 toward the downstream side so as to go to the central portion in the ventilation direction of the air-conditioning air A.

  Therefore, the air-conditioning air A flows along the main fins 31 and is collected around the main fins 31 by the upper auxiliary fins 33. The air-conditioning air A flows along the main fin 31 inclined so as to become higher toward the downstream side, and is blown out obliquely upward from the air outlet 14.

  When returning the main fin 31 from the above state to a state parallel to the second wall portion 22, a downward force is applied to the operation knob 40. By this force, the main fin 31 is tilted downward (counterclockwise direction) with the arm 59 and the support shaft 32 as a fulcrum. The engagement position of the transmission shaft 65 at the cam hole 69 changes from the downstream end of the first hole 69A toward the side closer to the boundary with the second hole 69B. Therefore, the inclined state in which the arm 64 is slightly higher toward the downstream side is maintained, and the auxiliary fin 35 is continuously accommodated in the lower accommodating recess 24 in a state parallel to the second wall portion 22. On the other hand, the engagement position of the transmission shaft 63 at the cam hole 68 changes from the upstream end of the second hole 68B toward the side closer to the boundary with the first hole 68A. Therefore, the arm 62 is tilted clockwise with the auxiliary shaft 33 and the support shaft 34 as a fulcrum. As shown in FIG. 8, when the arm 62 is inclined so as to be slightly lower toward the downstream side, the auxiliary fins 33 are parallel to the second wall portion 22 as shown in FIGS. 4 and 5. And stored in the upper storage recess 24.

  In FIG. 6, when a force in the first direction (vehicle width direction) is applied to the operation knob 40 (when the operation knob 40 is operated in the same direction), the operation knob 40 slides on the main fin 31. To do. The force applied to the operation knob 40 is transmitted to the transmission portion 54 of the central upstream fin 50 via the fork portion 41. The upstream fin 50 is tilted to the side in which the operation knob 40 is operated in the first direction (vehicle width direction) with the support shaft 52 as a fulcrum. The movement of the upstream fin 50 with the support shaft 52 as a fulcrum is transmitted to the other upstream fins 51 via the connection shaft 56 and the connection rod 57. By this transmission, all the upstream fins 51 are tilted to the operated side of the operation knob 40 in synchronization with the upstream fins 50. The air-conditioning air A flows along the upstream fins 50 and 51 tilted as described above, so that the direction thereof is changed and the air is blown out from the air outlet 14.

According to the embodiment described in detail above, the following effects can be obtained.
(1) Auxiliary fins 33 and 35 are arranged at locations close to the second wall portion 22 of the air passage 20 and supported by the first wall portion 21, and the main fin 31 is arranged between the auxiliary fins 33 and 35. It supports to the 1st wall part 21 (FIG. 4). A cam member 66 provided with a pair of cam holes 68 and 69 including first holes 68A and 69A and second holes 68B and 69B is supported by the case 10. The tilt of the main fin 31 is transmitted to the cam member 66 through the transmission mechanism 90 (FIG. 8).

  When the main fin 31 is made parallel to the second wall portion 22, the interlocking mechanism 60 causes the transmission shafts 63 and 65 of the auxiliary fins 33 and 35 to be connected to the first hole portions 68 </ b> A and 69 </ b> A of the cam holes 68 and 69. In addition, the auxiliary fins 33 and 35 are parallel to the second wall portion 22 by being positioned at the boundary between the second hole portions 68B and 69B (FIG. 8).

  When the main fin 31 is tilted from the above state, the transmission shafts 63 and 65 of the auxiliary fins 33 and 35 on the side close to the upstream end of the main fin 31 are positioned in the first holes 68A and 69A. The auxiliary fins 33 and 35 are set parallel to the second wall portion 22. By positioning the transmission shafts 65, 63 of the auxiliary fins 35, 33 far from the upstream end in the second holes 69 </ b> B, 68 </ b> B, the auxiliary fins 35, 33 are arranged at the downstream end to the inside of the ventilation path 20. It is made to incline with respect to the 2nd wall part 22 so that it may approach toward (FIG. 10, FIG. 12).

  (1A) Therefore, the clearance gap between each auxiliary fin 33 and 35 and the 2nd wall part 22 can be made small, and it can suppress that the air A for an air conditioning flows through this clearance gap. The pressure loss when the air-conditioning air A passes near the auxiliary fins 33 and 35 can be reduced.

  (1B) When the main fin 31 is inclined with respect to the second wall portion 22, the direction of the air conditioning air A flowing in the vicinity of the second wall portion 22 on the side far from the upstream end of the main fin 31 is the same. The auxiliary fins 35 and 33 on the side far from the upstream end can be changed to the inside of the ventilation path 20. Therefore, air-conditioning air A can be collected around the main fin 31 and the flow direction can be changed by the main fin 31. Therefore, the air-conditioning air A can be blown out from the outlet 14 toward the main fin 31, and the directivity of the air-conditioning air A when the main fin 31 is inclined with respect to both the second wall portions 22. Can be improved.

  (1C) Furthermore, when the main fin 31 is inclined with respect to the second wall portion 22, the auxiliary fins 33 and 35 on the side close to the upstream end of the main fin 31 are in a state parallel to the second wall portion 22. maintain. Therefore, even if the upstream end of the main fin 31 is brought close to the auxiliary fins 33 and 35, interference between the main fin 31 and the auxiliary fins 33 and 35 hardly occurs.

  Therefore, by arranging the auxiliary fins 33 and 35 and the second wall portion 22 on the side close to the upstream end of the main fin 31 at a location close to the main fin 31, the second direction (vertical direction) of the air-conditioning register is set. The dimensions can be reduced and the thickness can be further reduced.

  (1D) Although related to (1C) above, if the dimension in the second direction (vertical direction) of the air-conditioning register is sufficiently small and no further reduction in thickness is required, it is applied to the second wall portion 22. The upstream end of the main fin 31 inclined at the maximum angle obtained can be extended to a position close to the support shafts 34 and 36 of the auxiliary fins 33 and 35 that are parallel to the second wall portion 22. The dimension (width) of the main fin 31 in the ventilation direction can be increased.

  (1E) Unlike (1D) above, when the upstream end of the main fin 31 is not extended, the auxiliary fins 33 and 35 on the side close to the upstream end of the main fin 31 even if the main fin 31 is greatly inclined. Difficult to interfere with. Therefore, the maximum inclination angle of the main fin 31 can be enlarged. In this case, there is an advantage that the angle that can be adjusted with respect to the blowing direction of the air-conditioning air A is widened.

  (1F) Further, the clearance between the upstream end of the main fin 31 that is inclined at the maximum angle that can be taken and the auxiliary fins 33 and 35 on the side close thereto is reduced, and the air-conditioning air A flowing through this clearance is reduced. can do. In the ventilation path 20, the air-conditioning air A flowing between the main fin 31 and the second wall portion 22 on the side close to the upstream end can be blown out in the direction in which the main fin 31 faces.

  (2) In the air-conditioning register described in Patent Document 1, the auxiliary fin whose downstream end has protruded to the inside of the ventilation path is inclined toward the downstream side of the main fin. Therefore, some air-conditioning air whose direction is changed by the auxiliary fins does not hit the main fin. About this air-conditioning air, it is difficult to flow the air-conditioning air in the direction of the main fin.

  In this respect, in the present embodiment, when the main fin 31 is inclined with respect to the second wall portion 22 by the maximum angle that can be taken, the auxiliary fins 35 and 33 on the side far from the upstream end of the main fin 31 are connected to the main fin 31. It is made to incline toward the fin 31 (FIG. 9, FIG. 11).

  Therefore, in the ventilation path 20, the air-conditioning air A flowing between the main fin 31 and the second wall portion 22 on the side farther from the upstream end passes along the auxiliary fins 35 and 33 on the side farther from the upstream end. By making it flow, it can be made to contact the main fin 31 toward the main fin 31 side. As a result, more air-conditioning air A can be caused to flow in the direction toward the main fin 31.

  (3) The auxiliary fins 35 and 33 on the side farther from the upstream end of the main fin 31 inclined at the maximum angle that can be taken are centered in the main fin 31 with respect to the flow direction of the air conditioning air A in the ventilation path 20. It is made to incline toward the part used as a part (FIG. 9, FIG. 11).

  Therefore, in the ventilation path 20, the air-conditioning air A flowing along the second wall portion 22 on the side far from the upstream end of the main fin 31 is caused to flow along the auxiliary fins 35 and 33 on the side far from the upstream end. Thus, the direction of the main fin 31 can be changed to the center side. The air-conditioning air A is applied to the upstream portion of the main fin 31 with respect to the central portion, and the direction can be changed more accurately by flowing along the main fin 31.

  (4) In a state where the main fin 31 is inclined at the maximum angle that can be taken with respect to the second wall portion 22, a part (downstream end) of the operation knob 40 is moved away from the upstream end of the main fin 31. 35 and 33 are located downstream (FIGS. 9 and 11).

  Therefore, even if the air for air conditioning A tries to flow in parallel between the main fin 31 and the auxiliary fins 35 and 33 on the side far from the upstream end of the main fin 31 in parallel to the second wall portion 22. The air A can be applied to the operation knob 40 to flow in the direction toward the main fin 31, and it is possible to restrict the air A from being blown out straight from the air outlet 14. Therefore, also in this respect, the directivity of the air-conditioning air A when the main fin 31 is inclined with respect to the second wall portion 22 by the maximum angle that can be taken can be improved.

  (5) The arms 62 and 64 are extended from the support shafts 34 and 36 of the auxiliary fins 33 and 35 in a direction orthogonal to the support shafts 34 and 36. Transmission shafts 63 and 65 are provided at locations deviated from the support shafts 34 and 36 of these arms 62 and 64 (FIG. 2).

  Therefore, these transmission shafts 63 and 65 can function as engaging portions for the auxiliary fins 33 and 35. When the cam member 66 tilts as the main fin 31 tilts and the cam holes 68 and 69 are displaced, the positions of the transmission shafts 63 and 65 in the cam holes 68 and 69 are changed. When the transmission shafts 63 and 65 are positioned in the second holes 68B and 69B of the cam holes 68 and 69, the tilt of the cam member 66 is transmitted to the transmission shafts 63 and 65 through the wall surfaces of the cam holes 68 and 69, and moved. The arms 62 and 64 and the auxiliary fins 33 and 35 can be tilted in the second direction (vertical direction) with the support shafts 34 and 36 as fulcrums. When the transmission shafts 63 and 65 are positioned in the first holes 68A and 69A, the tilt of the cam member 66 is not transmitted to the transmission shafts 63 and 65 through the cam holes 68 and 69, and the arms 62 and 64 and the auxiliary fins 33 are transmitted. , 35 can be prevented from tilting.

(6) Cam holes 68 and 69 are provided in the cam member 66 supported so as to be tiltable in the second direction (vertical direction) by the shaft 28 with respect to the first wall portion 21 (FIGS. 7 and 8).
Therefore, the cam member 66 can function as a transmission member, and the cam holes 68 and 69 can function as engaged portions. When the main fin 31 is tilted from the state parallel to the second wall portion 22, the cam member 66 is tilted with the shaft 28 as a fulcrum, and the pair of cam holes 68 and 69 are swung around the shaft 28. The positions of the transmission shafts 63 and 65 for the auxiliary fins 33 and 35 in the cam holes 68 and 69 are changed. When the transmission shafts 63 and 65 are positioned in the second holes 68B and 69B, the tilt of the cam member 66 is transmitted to the auxiliary fins 33 and 35, and when the transmission shafts 63 and 65 are positioned in the first holes 68A and 69A, the cam member 66 is tilted. Can be prevented from being transmitted to the auxiliary fins 33, 35.

  (7) As a transmission mechanism 90 that transmits the tilt of the main fin 31 to the cam member 66, the arm 59 extending from the support shaft 32 of the main fin 31 in a direction orthogonal to the support shaft 32, and the support shaft 32 of the arm 59 A device provided with a transmission shaft 61 provided at a biased portion and engaged with a long hole 67 formed in the cam member 66 is employed (FIGS. 2 and 7).

  Therefore, when the main fin 31 is tilted in the second direction (vertical direction) with the arm 59 and the support shaft 32 as a fulcrum, the transmission shaft 61 is turned around the support shaft 32 and the cam member 66 is The cam member 66 can be tilted about the shaft 28 as a fulcrum by applying a force in two directions (up and down directions).

  (8) In the above-mentioned Patent Document 1, the cam members for each auxiliary fin each having a cam hole are overlapped in the vehicle width direction, and the transmission shaft of the main fin is engaged with the intersection of both cam holes. The dimension of the register in the first direction (vehicle width direction) is increased.

  In this regard, in this embodiment, the transmission shafts 63 and 65 of the auxiliary fins 33 and 35 are engaged with a pair of cam holes 68 and 69 provided in the cam member 66 driven by the main fin 31. Not too much (not superposed). Therefore, the dimension of the air conditioning register in the first direction (vehicle width direction) can be reduced.
