Description

  The present invention is applied to an air-conditioning register that blows air-conditioning air sent from an air-conditioning apparatus into a room from an outlet, and is operated when changing the blowing direction of the air-conditioning air. It relates to the operating mechanism.

  An air conditioning register for changing the direction of air conditioning air sent from the air duct of the air conditioner and blown into the passenger compartment is incorporated in the instrument panel of the vehicle. This air-conditioning register includes a retainer in which a ventilation path is formed. A ventilation path has a blower outlet in the downstream end of the flow direction of the air for an air conditioning. In the ventilation path, an upstream fin and a downstream fin for changing the blowing direction of the air-conditioning air from the air outlet are arranged along the flow direction of the air-conditioning air. The upstream fin is supported on the retainer by a fin shaft so as to be tiltable. The downstream fin is supported by the retainer so as to be tiltable by a fin axis extending in a direction orthogonal to the fin axis of the upstream fin. Further, a shut damper that adjusts the opening degree of the ventilation path is supported by the retainer so as to be tiltable by the retainer upstream of the upstream fin of the ventilation path.

The air conditioning register is provided with an operation mechanism that is operated to tilt the downstream fin, the upstream fin, and the shut damper.
For example, in the operation mechanism described in Patent Document 1, the shut damper is closed when the button is pushed forward, and the shut damper is opened when the button protrudes backward. When the protruding button is operated in the vertical direction, the downstream fin is tilted in the same direction, and when the button is operated in the left-right direction, the upstream fin is tilted in the same direction.

  In the operation mechanism described in Patent Document 2, when the button is operated in the left-right direction, the upstream fin is tilted in the same direction. The vertical movable region of the button includes a fin driving region for tilting the downstream fin in the vertical direction and a damper driving region set below the fin driving region for tilting the shut damper. When the button is operated in the vertical direction in the fin drive region, the downstream fin is tilted in the same direction. When the button is operated in the vertical direction in the damper driving area, the shut damper is tilted.

  Furthermore, in the operation mechanism described in Patent Document 3, the button includes a fin drive button that constitutes a central portion thereof, and an annular damper drive button that is disposed around the fin drive button. When the fin drive button is operated in the vertical direction, the downstream fin is tilted in the same direction, and when the fin drive button is operated in the left-right direction, the upstream fin is tilted in the same direction. When the damper drive button is rotated, the opening degree of the shut damper is changed.

  However, the operation mechanism described in Patent Document 1 can only open (fully open) or close (fully close) the shut damper, and cannot tilt the shut damper to an intermediate opening.

  Further, in the operation mechanism described in Patent Document 2, the opening degree of the shut damper can be changed only in a state where the downstream fin is tilted downward, and the air for air conditioning cannot be blown out in any direction from the outlet. .

  Further, in the operation mechanism described in Patent Document 3, when the operation for changing the opening degree of the shut damper is performed after changing the blowing direction of the air-conditioning air from the blower outlet, or vice versa The fin drive button and the damper drive button must be exchanged, and the operation is complicated.

  Such a problem occurs in common with an air conditioning register provided with a state adjusting unit that adjusts a state different from the blowing direction and the amount of air blowing out of the air outlet, instead of the shut damper. obtain.

  The present invention has been made in view of such circumstances, and the object thereof is to allow air conditioning air to be blown out from an air outlet in an arbitrary direction while making the state adjustment unit in an arbitrary state by a simple operation. It is an object to provide an air-conditioning register operating mechanism that can be used.

An air-conditioning register operating mechanism that solves the above problems is a retainer in which an air passage having an air outlet is formed at the downstream end of the air-conditioning air flow direction, and the air-conditioning air blowing direction from the air outlet is changed. Accordingly, the fin shafts are arranged along the flow direction and extend in directions orthogonal to each other, and the upstream fins and the downstream fins that are tiltably supported by the retainer, respectively, and function by applying rotational force, It is applied to an air conditioning register and a status adjustment unit that adjusts the state of the air-conditioning air blown from the outlet is operated to rotate the state adjusting unit with tilting the downstream fin and the upstream fins An air-conditioning register operating mechanism, wherein the operating member is disposed so as to be tiltable and rotatable outside the air outlet, and the downstream fin is tilted. The first transmission mechanism that transmits the tilt of the operation member to the downstream fin using a universal joint, and the tilt of the operation member in the direction in which the upstream fin is tilted using the universal joint And a third transmission mechanism that transmits the rotation of the operation member to the state adjustment unit via the shaft using the universal joint.

  According to said structure, when the operation member arrange | positioned outside the blower outlet of a retainer is tilted in the direction which tilts a downstream fin, the tilt will be downstream fin by the 1st transmission mechanism part using a universal joint. Is transmitted to. By this transmission, the downstream fin is tilted with the fin axis as a fulcrum.

  Further, when the operation member is tilted in a direction in which the upstream fin is tilted, the tilt is transmitted to the upstream fin by the second transmission mechanism portion using a universal joint. By this transmission, the upstream fin is tilted in the direction orthogonal to the downstream fin, with the fin axis extending in the direction orthogonal to the fin axis of the downstream fin as a fulcrum.

  The air-conditioning air flowing through the air passage in the retainer is changed in direction by flowing along the upstream fin and the downstream fin tilted as described above, and is blown out from the outlet. In this way, the direction in which the air-conditioning air is blown out from the outlet is changed.

Further, when the operation member is rotated, the rotation is transmitted to the state adjusting unit via the shaft by the third transmission mechanism unit using a universal joint. Conditioning unit turning force was applied is operated, the state of the air-conditioning air blown from the air outlet is adjusted.

  In this way, it is possible to tilt the upstream fin and the downstream fin by tilting the operation member, and to blow the air for air conditioning in an arbitrary direction from the outlet, and by rotating the operation member It is possible to set the state adjusting unit to an arbitrary state.

  In the operation mechanism of the air conditioning register, the universal joint includes a hemispherical shell-shaped outer shell member, a hemispherical shell-shaped intermediate shell member that is slidably engaged in the outer shell member, An inner shell member that has a hemispherical shell shape and is slidably engaged in the intermediate shell member, and the outer shell member and the intermediate shell member are each rotatably supported by a support shaft, The operation member is fixed to the inner shell member with a part thereof being inserted through the outer shell member and the intermediate shell member, and the inner shell member is a spherical engagement provided at the downstream end of the shaft. Part of the first transmission mechanism part is constituted by one of the outer shell member and the intermediate shell member, and the other part of the second transmission mechanism part is constituted by one of the outer shell member and the intermediate shell member. And a part of the third transmission mechanism portion by the inner shell member It is preferably made of.

Is done. The product itself is rotated about the support shaft, and the rotation is transmitted to the downstream fin. The downstream fin is tilted with the fin axis as a fulcrum. At this time, the outer shell member slides relative to the intermediate shell member. Therefore, the tilting of the operation member is not transmitted to the outer shell member and the intermediate shell member that constitute a part of the second transmission mechanism portion. Further, the tilting of the operating member is transmitted to the inner shell member, and the inner shell member is integrated with the operating member and rotates in the same direction as the tilting direction of the operating member. However, the tilting of the inner shell member is not transmitted to the shaft or hardly transmitted. Therefore, the upstream fin does not tilt, and the state of the state adjusting unit does not change or hardly changes.

  On the other hand, when the operating member is tilted in the direction in which the upstream fin is tilted, the tilt is transmitted to the outer shell member and the intermediate shell member that constitute a part of the second transmission mechanism portion. The product itself is rotated about the support shaft, and the rotation is transmitted to the upstream fin. The upstream fin is tilted about the fin axis as a fulcrum. At this time, the outer shell member slides relative to the intermediate shell member. Therefore, the tilting of the operation member is not transmitted to the outer shell member and the intermediate shell member that constitute a part of the first transmission mechanism portion. Further, the tilting of the operating member is transmitted to the inner shell member, and the inner shell member is integrated with the operating member and rotates in the same direction as the tilting direction of the operating member. However, the tilting of the inner shell member is not transmitted to the shaft or hardly transmitted. Therefore, the downstream fin does not tilt, and the state of the state adjusting unit does not change or hardly changes.

  Further, when the operating member is rotated, the inner shell member is rotated integrally with the operating member. At this time, the operation member is merely inserted through the outer shell member and the inner shell member, and the rotation of the operation member is hardly transmitted to the outer shell member and the inner shell member. Therefore, the downstream fin and the upstream fin do not tilt. The state adjustment unit is rotated to operate and change the state.

  In the operation mechanism of the air conditioning register, a protrusion is formed on the engaging portion, and the inner shell member extends along the flow direction of the air conditioning air, and the protrusion of the shaft is engaged. It is preferable that an engaging groove to be formed is formed.

To turn. At this time, the inner shell member slides with respect to the engagement portion of the shaft, and only changes the engagement state (for example, positional relationship) between the engagement groove and the protrusion, and the tilt of the operation member is not easily transmitted to the shaft. .

  On the other hand, when the operation member is rotated, the inner shell member is rotated integrally with the operation member. The rotation of the inner shell member is transmitted to the shaft through the engaging groove and the protrusion engaged therewith. The shaft rotates integrally with the operation member and the inner shell member. The state adjustment unit is rotated to operate and change the state.

  In the operation mechanism of the air conditioning register, a long hole extending along the supporting shaft is formed in each downstream portion of the outer shell member and the intermediate shell member. It is preferable that the outer shell member and the intermediate shell member are inserted through a portion where the holes intersect.

Communicated to things. This transmission is performed by applying the force of the operating member in a direction orthogonal to the direction in which the long hole extends.

  The tilting of the operating member is not transmitted to the outer shell member and the intermediate shell member that have a support shaft extending in a direction orthogonal to the fin axis of the downstream fin. This is because the operating member moves in the extending direction in the elongated hole extending along the support shaft.

  On the other hand, when the operation member is tilted in the direction in which the upstream fin is tilted, the tilt is transmitted to the outer shell member and the intermediate shell member having the support shaft extending in the same direction as the fin axis of the upstream fin. Is done. This transmission is performed by applying the force of the operating member in a direction orthogonal to the direction in which the long hole extends.

  The tilting of the operating member is not transmitted to the outer shell member and the intermediate shell member that have a support shaft extending in a direction orthogonal to the fin axis of the upstream fin.

Is configured.

  As shown in FIGS. 5, 10 and 12, the intermediate shell member 97 constitutes a part of the second transmission mechanism portion TM2. The second transmission mechanism portion TM2 transmits the movement of the operation member 81 in the direction along the long side portion 45 (left-right direction, vehicle width direction) to the plurality of upstream fins 71, and uses the fin shaft 72 as a fulcrum to each upstream fin. 71 is a mechanism for tilting 71.

In addition to the intermediate shell member 97, the second transmission mechanism portion TM2 includes a drive gear 111, a transmission gear 114, a driven gear 115, and a rod 112.
The drive gear 111 has a flat fan shape, and is formed on the lower support shaft 98 of the intermediate shell member 97. The drive gear 111 is inserted through the through hole 93 of the base portion 82.

  A rod 112 extending in the left-right direction (vehicle width direction) is disposed in the groove portion 21 of the bottom wall portion 39 and the groove portion 23 of the extension portion 22 in a state of passing through the communication hole. In this rod 112, holes 113 are formed at positions spaced apart from each other at substantially equal intervals in the left-right direction (vehicle width direction), and the connecting pins 73 of the respective upstream fins 71 are inserted into these holes 113.

  In addition to the inner shell member 101, the third transmission mechanism part TM3 includes the shaft 87 and the bevel gear mechanism described above. The bevel gear mechanism is for transmitting the rotation of the shaft 87 orthogonal to the damper shaft 76 of the shut damper 75 to the damper shaft 76. The bevel gear mechanism is a combination of a drive-side bevel gear 118 formed on the upstream end of the shaft 87 and a driven-side bevel gear 119 formed on the right damper shaft 76 and meshed with the bevel gear 118. Consists of.

Next, the operation of the present embodiment configured as described above will be described.
11 and 12, the operating member 81 is located at the center of the movable region in the up-down direction and at the center of the movable region in the left-right direction (vehicle width direction), The state of each part when located is shown. The state of the operation member 81 at this time is referred to as a “neutral state”. In the neutral state, the shaft portion 81 b of the operation member 81 is located on the same axis as the shaft 87. At this time, in the damper movable range defining portion 77, as shown by the solid line in FIG. 15, the protruding portion 79 is in contact with one (left side) stopper 78 a of the arc portion 78. The shut damper 75 is in a posture (horizontal state) along the flow direction of the air-conditioning air A1 before being introduced into the ventilation path 35, that is, in a fully open state (see FIG. 13).

  As shown in FIG. 10, in the second transmission mechanism portion TM <b> 2, the connecting pin 116 of the driven gear 115 is located upstream of the shaft portion 24. In each upstream fin 71, the connecting pin 73 is located upstream of the fin shaft 72. As a result, as shown by a solid line in FIG. 11, each upstream fin 71 is in a posture along the flow direction of the air-conditioning air A <b> 1 before being introduced into the ventilation path 35. Each upstream fin 71 is substantially parallel to both side walls 36 and 37 of the retainer 10.

  As shown in FIGS. 16 and 17, in the first transmission mechanism portion TM1, the drive gear 103 and the first transmission gear 104 are engaged with each other at the teeth in the central portion in the circumferential direction. Both downstream portions 67b and the auxiliary fins 68 in the barrel 65 are in a posture (substantially horizontal state) along the flow direction of the air-conditioning air A1 before being introduced into the ventilation path 35.

  Further, the second transmission gear 105 and the driven gear 106 are meshed with each other at the teeth of the central portion in the circumferential direction. Similarly to the barrel 65, the second fin 61 is in a posture (substantially horizontal state) along the flow direction of the air-conditioning air A1 before being introduced into the ventilation path 35. The same applies to the first fin 55 connected to the second fin 61 via the rod 109. Moreover, the first fin 55 and the second fin 61 are located at substantially the same height as the downstream portions 67b.

  Therefore, as shown in FIGS. 11, 13, and 14, the air-conditioning air A <b> 1 that flows into the air-conditioning thin register first flows separately on the upper side and the lower side of the shut damper 75. The air conditioning air A1 that has passed through the shut damper 75 flows between the adjacent upstream fins 71 or between the upstream fins 71 at both ends in the left-right direction (vehicle width direction) and the side wall portions 36, 37 of the retainer 10. It flows into the barrel 65. Here, the upstream part 67a of both the main fins 67 in the barrel 65 is inclined with respect to the downstream part 67b. In the main fin 67, the distance between the two upstream portions 67a increases toward the upstream. Therefore, the air-conditioning air A1 that has flowed into the barrel 65 flows along the inclined upstream portion 67a of both the main fins 67 and is collected between the downstream portions 67b. The air conditioning air A <b> 1 flows between the downstream portion 67 b and the auxiliary fins 68 along the downstream portion 67 b and the auxiliary fins 68. Thereafter, the air-conditioning air A <b> 1 flows between the first fins 55 and the second fins 61 along the fins 55 and 61. As a result, a large amount of air-conditioning air A1 is blown straight out from the outlet 43 to the downstream side without changing the direction in which it flows in the left-right direction (vehicle width direction) or the vertical direction.

  When the knob 81a of the operation member 81 in the neutral state is picked and an upward force is applied in the direction (vertical direction) along the short side portion 44 of the air outlet 43, the force is applied to the axis of the operation member 81. It is transmitted to the inner shell member 101 fixed to the portion 81b. The inner shell member 101 is engaged with the inner surface of the inner shell member 101 in contact with the outer surface of the engaging portion 88 of the shaft 87. Further, the inner shell member 101 is engaged with the outer surface thereof in contact with the inner surface of the intermediate shell member 97.

  Further, the elongated hole 96 of the outer shell member 94 through which the shaft portion 81 b of the operation member 81 is inserted extends in the left-right direction (vehicle width direction), and this direction is a direction orthogonal to the operation direction of the operation member 81. . Further, the long hole 99 of the intermediate shell member 97 through which the shaft portion 81 b of the operation member 81 is inserted extends in the vertical direction, and this direction is the same as the operation direction of the operation member 81. Therefore, the upward force applied to the operation member 81 is transmitted to the outer shell member 94 through the wall surface of the long hole 96 extending in the left-right direction (vehicle width direction). Further, the above upward force is not transmitted to the intermediate shell member 97. This is because the shaft portion 81b of the operation member 81 moves upward along the long hole 99 extending in the vertical direction.

  The operating member 81 is engaged by the inner shell member 101 integrated therewith sliding upward with respect to the engaging portion 88 of the shaft 87 and the shaft portion 81b moving upward along the long hole 99. It is tilted upward with the joint 88 as a fulcrum. As shown in FIG. 18, the outer shell member 94 that has received an upward force through the shaft portion 81 b of the operation member 81 in the long hole 96 slides upward with respect to the intermediate shell member 97. Turn clockwise. Accordingly, the drive gear 103 formed on the support shaft 95 rotates in the clockwise direction in FIG. This rotation is transmitted to the fin shaft 69 of the barrel 65 via the first transmission gear 104 meshed with the drive gear 103 as shown in FIG. The first transmission gear 104 is rotated in the counterclockwise direction, which is the opposite direction to the drive gear 103, with the barrel 65 and the second transmission gear 105, so that both the downstream portions 67b and the auxiliary fins 68 are connected to the downstream side. Inclined so that it becomes lower.

  The rotation of the second transmission gear 105 is transmitted to the second fin 61 via the driven gear 106 and the fin shaft 62 meshed with the second transmission gear 105, and the second fin 61 is transmitted to the fin shaft. With reference to 62 as a fulcrum, it is tilted in the opposite direction to the barrel 65 (the same direction as the operation member 81).

  The tilt of the second fin 61 is also transmitted to the first fin 55 via the rod 109 and the connecting pins 108 and 107 as shown in FIG. The first fin 55 tilts clockwise around the fin shaft 56 in synchronization with the second fin 61 in a state parallel to the second fin 61. In this way, the first fin 55 and the second fin 61 tilt in the opposite direction to the barrel 65 with the fin shafts 56 and 62 as fulcrums. The 2nd fin 61 and the 2nd fin 61 will be in the state inclined so that it might become low toward the upstream.

  Accordingly, as shown in FIG. 19, the air-conditioning air A1 that has flowed into the barrel 65 after passing through the upstream fin 71 flows between the two downstream portions 67b inclined as described above and flows along the bottom wall portion 39. Thus, it is guided between the upstream end of the first fin 55 and the upstream end of the second fin 61.

  Here, the two downstream portions 67b of the barrel 65 are spaced apart from each other in parallel, and the auxiliary fins 68 are disposed between the main fins 67 in parallel to the downstream portion 67b. Therefore, the air-conditioning air A1 flows along the auxiliary fins 68 in addition to the downstream portions 67b when passing through the barrel 65. Therefore, the air-conditioning air A <b> 1 is more easily guided between the upstream end of the first fin 55 and the upstream end of the second fin 61 than when the auxiliary fin 68 is not provided.

  The air-conditioning air A <b> 1 flows between the first fin 55 and the second fin 61, thereby changing the flowing direction, and is blown out obliquely upward from the air outlet 43. In this way, the angle α formed with respect to the short side portion 44 of the air-conditioning air A1 blown out from the outlet 43 is changed.

  Note that when an upward force is applied to the operation member 81 as described above, the force is not transmitted to the intermediate shell member 97. The intermediate shell member 97 does not rotate with the support shaft 98 as a fulcrum, and therefore the upstream fin 71 does not tilt. At this time, the inner shell member 101 is integrated with the operation member 81 and is rotated upward in the same direction as the tilt direction of the operation member 81. At this time, the inner shell member 101 slides with respect to the engaging portion 88 of the shaft 87, and only changes the engagement state (for example, positional relationship) between the engagement groove 102 and the projection 89, and the operation member 81 is tilted. Is difficult to be transmitted to the shaft 87. The shaft 87 hardly rotates, and therefore the opening degree of the shut damper 75 hardly changes.

  Contrary to the above, when the knob 81a of the operation member 81 is picked and a downward force is applied from the neutral state, as shown in FIG. While sliding downward with respect to the engaging portion 88 of 87, the shaft portion 81b moves downward along the long hole 99, so that the engaging portion 88 is tilted downward. The outer shell member 94 that has received a downward force through the shaft portion 81b of the operation member 81 slides downward with respect to the intermediate shell member 97, and thus rotates counterclockwise in FIG. Move. Accordingly, the drive gear 103 formed on the support shaft 95 rotates in the same direction. This rotation is transmitted to the fin shaft 69 of the barrel 65 via the first transmission gear 104. The first transmission gear 104 is tilted in the clockwise direction, which is the direction opposite to the tilting direction of the operation member 81, together with the barrel 65 and the second transmission gear 105, so that both the downstream portions 67b and the auxiliary fins 68 are It inclines so that it may become higher downstream.

  The rotation of the second transmission gear 105 is transmitted to the second fin 61 via the driven gear 106 and the fin shaft 62, and the second fin 61 is opposite to the barrel 65 with the fin shaft 62 as a fulcrum. It is tilted in the direction (the same direction as the operation member 81).

  The tilt of the second fin 61 is also transmitted to the first fin 55 via the rod 109 as shown in FIG. The first fin 55 tilts counterclockwise around the fin shaft 56 in synchronization with the second fin 61 in a state parallel to the second fin 61. In this way, the first fin 55 and the second fin 61 are tilted in the direction opposite to the tilting direction of the barrel 65 with the fin shafts 56 and 62 as fulcrums. The 2nd fin 61 and the 2nd fin 61 will be in the state which inclined so that it might become higher toward the upstream.

  Accordingly, as shown in FIG. 23, the air-conditioning air A1 that has flowed into the barrel 65 after passing through the upstream fin 71 flows between the two downstream portions 67b inclined as described above and flows along the upper wall portion 38. Thus, it is guided between the upstream end of the first fin 55 and the upstream end of the second fin 61.

  In this case as well, the air-conditioning air A1 flows along the auxiliary fins 68 in addition to the downstream portions 67b when passing between the main fins 67. Therefore, the air-conditioning air A <b> 1 is easily guided between the upstream end of the first fin 55 and the upstream end of the second fin 61 as compared with the case where the auxiliary fin 68 is not provided.

  The air-conditioning air A <b> 1 flows between the first fins 55 and the second fins 61, thereby changing the flowing direction, and is blown out obliquely downward from the air outlet 43. In this way, the angle α formed with respect to the short side portion 44 of the air-conditioning air A1 blown out from the outlet 43 is changed.

  Note that when a downward force is applied to the operation member 81 as described above, the force is not transmitted to the intermediate shell member 97. The intermediate shell member 97 does not rotate with the support shaft 98 as a fulcrum, and therefore the upstream fin 71 does not tilt. At this time, the inner shell member 101 is integrated with the operation member 81 and is rotated downward in the same direction as the tilt direction of the operation member 81. At this time, the inner shell member 101 slides with respect to the engaging portion 88 of the shaft 87, and only changes the engagement state (for example, positional relationship) between the engagement groove 102 and the projection 89, and the operation member 81 is tilted. Is difficult to be transmitted to the shaft 87. The shaft 87 hardly rotates, and therefore the opening degree of the shut damper 75 hardly changes.

  By the way, both the downstream parts 67b are spaced apart from each other in parallel. Further, the first fin 55 and the second fin 61 are arranged in parallel to each other. Therefore, even when the operation member 81 is tilted in the vertical direction as described above, the air-conditioning air A1 flows between the two downstream portions 67b and between the first fin 55 and the second fin 61 in the ventilation path 35. In this case, the flow path cross-sectional area does not change greatly.

  In particular, in the present embodiment, as shown in FIGS. 14 and 19, the fin shaft 56 is positioned in the vicinity of the upstream side of the upper long side portion 45, and the fin shaft 62 is positioned in the vicinity of the upstream side of the lower long side portion 45. It is located and the space | interval of the 1st fin 55 and the 2nd fin 61 approximates the length L1 of the short side part 44 of the blower outlet 43. FIG. An interval D2 between the two downstream portions 67b is set to an interval that matches or approximates the length L1 of the short side portion 44. With such a setting, the flow path cross-sectional area between the two downstream portions 67 b becomes approximately the same as the flow path cross-sectional area between the first fin 55 and the second fin 61. Therefore, the flow passage cross-sectional area does not change greatly until the air-conditioning air A1 is blown out from the outlet 43 through the first fin 55 and the second fin 61 between the two downstream portions 67b.

  Further, in this embodiment, as shown in FIG. 13, the dimension (interval D1) in the direction along the short side portion 44 matches the length L1 of the short side portion 44 upstream of the barrel 65 of the retainer 10. Or it is set to the approximate dimension. Therefore, if both the main fins 67 in the barrel 65 are spaced apart from each other in the upstream portion 67a in the same manner as the downstream portion 67b, the barrel 65 is tilted and the both downstream portions 67b are moved with respect to the short side portion 44. When inclined, the upstream portion 67a protrudes into the ventilation path 35, and becomes a flow resistance of the air-conditioning air A1.

  In this regard, in the present embodiment in which both upstream portions 67a are inclined with respect to the downstream portion 67b so that the distance between the upstream portions 67a increases toward the upstream side, as shown in FIGS. 19 and 23, the upstream portion 67a has a ventilation path. Protruding into 35 is suppressed, and ventilation resistance is suppressed.

  From the neutral state, when the knob 81a of the operation member 81 is picked and a rightward force is applied in the left and right direction (vehicle width direction), for example, the force is applied to the axis of the operation member 81. It is transmitted to the inner shell member 101 fixed to the portion 81b.

  Here, the long hole 96 of the outer shell member 94 through which the shaft portion 81 b of the operation member 81 is inserted extends in the left-right direction (vehicle width direction), and this direction is the same as the operation direction of the operation member 81. . Further, the long hole 99 of the intermediate shell member 97 into which the shaft portion 81 b of the operation member 81 is inserted extends in the vertical direction, and this direction is a direction orthogonal to the operation direction of the operation member 81.

  Therefore, the rightward force applied to the operation member 81 is transmitted to the intermediate shell member 97 through the wall surface of the long hole 99 extending in the vertical direction. Further, the above-mentioned force directed to the right is not transmitted to the outer shell member 94. This is because the shaft portion 81b of the operation member 81 moves to the right along the long hole 96 extending in the left-right direction.

  Therefore, as shown in FIG. 26, the operation member 81 has the inner shell member 101 sliding to the right with respect to the engaging portion 88 of the shaft 87 and the shaft portion 81 b moving to the right along the long hole 96. By doing so, it is tilted rightward with the engaging portion 88 as a fulcrum. The intermediate shell member 97 that has received a rightward force through the shaft portion 81b of the operation member 81 slides to the right with respect to the outer shell member 94, thereby rotating counterclockwise about the support shaft 98 as a fulcrum. To do. Accordingly, as shown in FIG. 27, the drive gear 111 formed on the support shaft 98 rotates counterclockwise. This rotation is transmitted to the transmission gear 114 meshed with the drive gear 111, and the transmission gear 114 rotates in the opposite direction to the drive gear 111. The rotation of the transmission gear 114 is transmitted to a driven gear 115 meshed with the transmission gear 114, and the driven gear 115 rotates in the same direction as the drive gear 111. Along with this, the connecting pin 116 of the driven gear 115 turns around the shaft portion 24 in the counterclockwise direction. A leftward force is applied to the rod 112 through the connecting pin 116, and the rod 112 moves to the left in the grooves 21 and 23. A leftward force is applied to the connecting pin 73 of each upstream fin 71 through the rod 112. Each upstream fin 71 tilts counterclockwise with the fin shaft 72 as a fulcrum in a synchronized state so as to be parallel to each other. As shown by a two-dot chain line in FIG. 11, each upstream fin 71 is inclined so as to be positioned to the right as it is downstream.

Therefore, the air-conditioning air A1 that has passed through the shut damper 75 can flow in the right direction by flowing between the upstream fins 71 that are inclined as described above.
The air-conditioning air A <b> 1 flows between the main fins 67 in the barrel 65 and between the first fin 55 and the second fin 61 in order, and then is changed from the outlet 43 by the upstream fin 71 ( It blows out toward the right). In this way, the angle β formed with respect to the long side portion 45 of the air-conditioning air A1 blown out from the air outlet 43 is changed.

  By the way, when the rightward force is applied to the operation member 81 as described above, the force is not transmitted to the outer shell member 94 as described above. The outer shell member 94 does not rotate with the support shaft 95 as a fulcrum, and therefore the barrel 65, the first fin 55, and the second fin 61 do not tilt. At this time, the inner shell member 101 is integrated with the operation member 81 and is rotated to the right, which is the same direction as the tilting direction of the operation member 81. At this time, the inner shell member 101 slides with respect to the engaging portion 88 of the shaft 87, and only changes the engagement state (for example, positional relationship) between the engagement groove 102 and the projection 89, and the operation member 81 is tilted. Is difficult to be transmitted to the shaft 87. The shaft 87 hardly rotates, and therefore the opening degree of the shut damper 75 hardly changes.

  In addition, when a force toward the left is applied to the operation member 81 from the neutral state, each part of the transmission mechanism TM is in the opposite direction to the case where the force toward the right is applied to the operation member 81 described above. To operate.

  When the knob 81a of the operation member 81 is picked from the neutral state and a circumferential force is applied, the force is transmitted to the inner shell member 101 fixed to the shaft portion 81b of the operation member 81. The inner shell member 101 rotates together with the operation member 81. This rotation is transmitted to at least one protrusion 89 of the engaging portion 88 of the shaft 87 via the engaging groove 102 on the inner surface of the inner shell member 101. By this transmission, the shaft 87 extending in the flow direction of the air-conditioning air A <b> 1 rotates with the driving-side bevel gear 118. The rotation is transmitted to the damper shaft 76 orthogonal to the flow direction through the driven bevel gear 119. At this time, the bevel gears 118 and 119 change the direction of the transmitted rotation. When the shut damper 75 is tilted with the damper shaft 76 as a fulcrum, the opening degree of the shut damper 75 changes to an opening degree corresponding to the rotation amount (angle) of the operation member 81. The amount of air-conditioning air A1 passing through the shut damper 75 in the ventilation path 35 is adjusted, and the amount of air-conditioning air A1 blown out from the outlet 43 is adjusted.

  When the operation member 81 is rotated as described above, the rotation is not transmitted to the outer shell member 94 and the inner shell member 101. This is because the operation member 81 is merely inserted through the outer shell member 94 and the inner shell member 101. Therefore, neither the barrel 65 nor the upstream fin 71 is tilted.

  Further, the protrusion 79 formed on the damper shaft 76 rotates as indicated by the two-dot chain line arrow in FIG. 15 as the damper shaft 76 rotates. Then, as shown by a two-dot chain line in FIG. 14, when the shut damper 75 is tilted to an angle at which the shut damper 75 is fully closed, the projection 79 comes into contact with the stopper 78a on the right side in FIG. Is regulated.

According to the embodiment described in detail above, the following effects can be obtained.
(1) The operation member 81 is disposed so as to be tiltable and rotatable. A first transmission that transmits the tilt of the operation member 81 in the direction of tilting the barrel 65, the first fin 55, and the second fin 61 to the barrel 65, the first fin 55, and the second fin 61 using a universal joint. A transmission mechanism TM1 is provided. A second transmission mechanism portion TM2 is provided that transmits the tilt of the operation member 81 in the direction of tilting the upstream fin 71 to the upstream fin 71 using a universal joint. Further, a third transmission mechanism part TM3 for transmitting the rotation of the operation member 81 to the shut damper 75 via the shaft 87 using a universal joint is provided (FIGS. 10 and 11).

Therefore, by performing a simple operation such as picking and tilting the operation member 81, the first fin 55, the second fin 61, the barrel 65, and the upstream fin 71 are tilted, and the air for air conditioning A1 is discharged from the outlet 43. Can be blown out in any direction,
Further, by performing a simple operation such as turning the picked operation member 81, the opening degree of the shut damper 75 can be adjusted, and the amount of air-conditioning air A1 blown out from the air outlet 43 can be adjusted. When adjusting the blowing amount after changing the blowing direction of the air-conditioning air A1, or conversely, when adjusting the blowing direction after adjusting the blowing amount, the knob 81a of the operation member 81 need not be changed. Easy to operate.

  (2) When the operation member 81 is disposed at the air outlet 43, the operation member 81 becomes a ventilation resistance and causes an increase in pressure loss. Moreover, when a fin is arrange | positioned, for example in the center part between the 1st fin 55 and the 2nd fin 61, the performance (directivity) which changes the blowing direction of air-conditioning air A1 can be improved, but this also Ventilation resistance and pressure loss increases.

  In this regard, in the present embodiment, the operation member 81 is disposed outside the air outlet 43 (FIG. 11). Further, no fin is provided between the first fin 55 and the second fin 61 (FIG. 13).

Therefore, it is possible to suppress an increase in ventilation resistance due to the operation member 81 and the fins between the first fin 55 and the second fin 61, and thus an increase in pressure loss.
(3) Further, when a fin is newly arranged between the first fin 55 and the second fin 61, the first fin 55 and the second fin 61 are restricted in arrangement accordingly. This is because the gap between adjacent fins becomes small and may interfere when tilted.

However, in the present embodiment, as described above, no new fins are used (FIG. 13), so the degree of freedom in arranging the first fins 55 and the second fins 61 is increased.
(4) An outer shell member 94 having a hemispherical shell shape is slidably engaged with an intermediate shell member 97 having a hemispherical shell shape, and further, an inner shell member having a hemispherical shell shape is formed within the intermediate shell member 97. 101 is slidably engaged. These outer shell member 94, intermediate shell member 97 and inner shell member 101 constitute a universal joint. The outer shell member 94 is supported by a support shaft 95 extending in the same direction as the fin shafts 69, 56, and 62 of the barrel 65, the first fin 55, and the second fin 61 so as to be rotatable in the vertical direction. The intermediate shell member 97 is supported by a support shaft 98 extending in the same direction as the fin shaft 72 of each upstream fin 71 so as to be rotatable in the left-right direction (vehicle width direction).

  The shaft portion 81 b of the operation member 81 is fixed to the inner shell member 101 while being inserted through the outer shell member 94 and the intermediate shell member 97. The inner shell member 101 is engaged with the shaft 87 so as to transmit the rotation. The outer shell member 94 constitutes a part of the first transmission mechanism part TM1, the intermediate shell member 97 constitutes a part of the second transmission mechanism part TM2, and the inner shell member 101 constitutes the third transmission mechanism part TM3. A part is configured (FIGS. 7 and 12).

  Therefore, by operating the operation member 81 and rotating the outer shell member 94 in the first transmission mechanism portion TM1 in the vertical direction about the support shaft 95, the other members of the first transmission mechanism portion TM1 can rotate. The barrel 65, the first fin 55, and the second fin 61 can be tilted in the same direction.

  Further, by operating the operation member 81 and rotating the intermediate shell member 97 in the second transmission mechanism portion TM2 in the left-right direction (vehicle width direction) with the support shaft 98 as a fulcrum, the second transmission mechanism portion TM2 is rotated. The upstream fin 71 can be tilted in the same direction by another member.

  Further, the operation member 81 is rotated, and the inner shell member 101 in the third transmission mechanism part TM3 is rotated integrally with the operation member 81, so that the other members of the third transmission mechanism part TM3 cause the shut damper. The opening degree can be adjusted by tilting 75.

  (5) A spherical engagement portion 88 formed at the downstream end of the shaft 87 is slidably engaged with the inner shell member 101. An engagement groove 102 extending along the flow direction of the air conditioning air A1 is formed on the inner surface of the inner shell member 101, and a protrusion 89 protruding from the engagement portion 88 is engaged therewith (FIG. 8 ( a), (b)).

  Therefore, when the operation member 81 is tilted in the vertical direction with the inner shell member 101 or tilted in the left-right direction (vehicle width direction), the tilt is not transmitted to the shaft 87 at all or hardly. When the member 81 is rotated, the rotation can be transmitted to the shaft 87 and the shaft 87 can be rotated.

  (6) In the downstream portion of the outer shell member 94, a long hole 96 extending left and right (vehicle width direction) along its own support shaft 95 is formed. In the downstream portion of the intermediate shell member 97, a long hole 99 extending in the vertical direction along its own support shaft 98 is formed. The shaft 81b of the operation member 81 is inserted through the outer shell member 94 and the intermediate shell member 97 at a portion where these long holes 96 and 99 intersect (FIG. 7).

  Therefore, when an upward or downward force is applied to the operation member 81, the outer shell member 94 can be rotated in the same direction. Further, when a leftward or rightward force is applied to the operation member 81, the intermediate shell member 97 can be rotated in the same direction.

  (7) As the first transmission mechanism portion TM1, a device having a plurality of gears (drive gear 103, first transmission gear 104) between the support shaft 95 of the outer shell member 94 and the fin shaft 69 of the barrel 65 is used. (FIG. 11).

  Therefore, when the operation member 81 is tilted in the vertical direction and the outer shell member 94 is rotated in the same direction with the support shaft 95 as a fulcrum, the rotation is performed by a plurality of gears (drive gear 103, first transmission gear 104). It is transmitted to the fin shaft 69 through the barrel and the barrel 65 can be tilted.

  (8) As the second transmission mechanism portion TM2, a plurality of gears (drive gear 111, transmission gear 114, driven gear 115) are provided between the support shaft 98 of the intermediate shell member 97 and the fin shaft 72 of each upstream fin 71. A thing is used (FIG. 10).

  Therefore, when the operation member 81 is tilted in the left-right direction (vehicle width direction) and the intermediate shell member 97 is rotated in the same direction with the support shaft 98 as a fulcrum, the rotation is transmitted to a plurality of gears (drive gear 111, transmission). It is transmitted to each upstream fin 71 via the gear 114 and the driven gear 115), and the upstream fin 71 can be tilted.

  (9) As the third transmission mechanism part TM3, in addition to the inner shell member 101 and the shaft 87, a bevel gear mechanism comprising a combination of bevel gears 118 and 119 between the shaft 87 and the damper shaft 76 of the shut damper 75. (FIG. 11) is used.

  Therefore, when the operation member 81 is rotated, the rotation can be transmitted to the shut damper 75 via the inner shell member 101, the shaft 87, and the bevel gear mechanism. By finely adjusting the opening degree of the shut damper 75, the amount of air-conditioning air A1 blown out can be adjusted to an arbitrary amount.

(10) The adjustment of the blowing direction of the air-conditioning air A1 and the adjustment of the blowing amount are performed by operating a common member (operation member 81) (FIG. 11).
Therefore, compared with Patent Document 3 in which an annular damper drive button is arranged around the fin drive button, the member (operation member 81) operated when adjusting the blowing direction and adjusting the blowing amount is downsized. Can do. This is suitable for the case where the vertical dimension is small like the thin air-conditioning register and a small operation member 81 is used accordingly.

Moreover, since the design of the member operated when adjusting the blowing direction of air-conditioning air A1 and the design of the member operated when adjusting the blowing amount are the same, the design is improved.
In addition, the said embodiment can also be implemented as a modification which changed this as follows.

In this case, the plurality of fins are arranged in the retainer 10 in a state of being arranged in the thickness direction thereof. Each fin is supported by the retainer 10 so as to be tiltable by a fin shaft. Further, when the operation member 81 is rotated in one direction between the operation member 81 and each fin, the interval between the upstream ends of the adjacent fins is narrowed and is rotated in the opposite direction. A third transmission mechanism for transmitting the rotation of the operation member 81 to each fin is provided so that the interval between the upstream ends adjacent to each other is wide. Even in the third transmission mechanism portion, the rotation of the operation member 81 is transmitted to the state adjustment portion via the shaft 87 using a universal joint.

  When the operating member 81 is rotated in one direction as described above, the interval between the downstream ends of adjacent fins is widened, and the air for air conditioning A1 is blown out from the outlet 43 in a diffused state. When the operation member 81 is rotated in the opposite direction, the interval between the downstream ends of adjacent fins is narrowed, and the air-conditioning air A1 is blown out from the outlet 43 in a converged state.

  Further, as one form of the air conditioner, there is one that includes a switch that is rotated when adjusting the temperature of the air-conditioning air A1 that is blown out from the air outlet 43. This switch may be a state adjusting unit, and a third transmission mechanism unit that transmits the rotation of the operation member 81 to the switch may be provided between the switch and the operation member 81. Even in the third transmission mechanism portion, the rotation of the operation member 81 is transmitted to the state adjustment portion via the shaft 87 using a universal joint.
