Definitions
- the present invention relates to an air-conditioning register that blows out air-conditioning air, which is delivered from an air conditioner, through the outlet of an airflow passage.
- Vehicles have air-conditioning registers, which are configured to change the direction in which air-conditioning air from the air duct of the air conditioner is blown into the passenger compartment.
- air-conditioning register includes fins and a retainer having an airflow passage, through which air-conditioning air flows.
- the fins are arranged in the airflow passage and tiltably supported by the retainer with fin pivots.
- Each fin has a coupling pin at a position displaced from the fin pivot.
- the fins are arranged parallel with each other, and the coupling pins are coupled to each other by a coupling link. This allows all the fins to be tilted while being arranged parallel with each other.
- Air-conditioning air is blown out from the outlet such that the air-conditioning air flows along the adjacent fins and the like, and in parallel streams through all the spaces in between and the like.
- the blow mode in which the air-conditioning air is blown out in this manner is referred to as a parallel blow mode.
- Japanese Laid-Open Patent Publication No. 2002-293133 discloses an air-conditioning register that implements a diffusion blow mode and a concentration blow mode as non-parallel blow modes.
- adjacent fins are tilted such that the spaces in between at the upstream end are narrower than those at the downstream end.
- the air-conditioning air flows along the adjacent fins and the like through spaces in between to be diffused to a wider area toward the downstream end.
- a weaker flow of air-conditioning air is blown onto a wider area of the body of an occupant than in a case in which the parallel blow mode is selected.
- adjacent fins are tilted such that the spaces in between at the upstream end are wider than those at the downstream end.
- the air-conditioning air flows along adjacent fins and the like through spaces in between to be converged to reach areas that are narrowed down toward the downstream end. A stronger flow of air-conditioning air is blown onto a narrower area of the body of an occupant than in a case in which the parallel blow mode is selected.
- the configuration of the publication employs a guide link in addition to the coupling link.
- the coupling link has support holes, the number of which is equal to that of the fins
- the guide link has guide holes, the number of which is equal to that of the fins.
- a coupling pin associated with one of the fins is received by the intersecting parts of one of the support holes and the corresponding guide hole.
- the guide link and the coupling link are lifted or lowered, so that the fins are tilted while being maintained parallel. That is, when the parallel blow mode is selected, the direction of the parallel streams of the air-conditioning air is changed.
- the passenger may desire to change the part onto which the diffused air-conditioning air is blown. Also, when selecting the concentration blow mode, the passenger may desire to change the part onto which the converged air-conditioning air is blown.
- the air-conditioning register of Japanese Laid-Open Patent Publication No. 2002-293133 which tilts the fins by changing the positions of the intersecting parts of the support holes and the guide holes, has a limitation in increasing the patterns of tilting of the fins and thus cannot meet the above described needs.
- an objective of the present invention to provide an air-conditioning register that is capable of changing the direction of air-conditioning air not only in the parallel blow mode, but also in the non-parallel blow modes.
- an air-conditioning register that includes a retainer, a plurality of fins, a coupling plate, and a drive mechanism.
- An airflow passage is provided in the retainer.
- the airflow passage has an outlet at a downstream end in a flowing direction of air-conditioning air.
- the fins are arranged in the airflow passage and tiltably supported by the retainer with fin pivots.
- Each fin has a coupling pin at a position displaced from the fin pivot.
- the coupling plate couples the fins together at the coupling pins.
- the drive mechanism changes a position of the coupling plate in the flowing direction.
- the coupling pins which are respectively associated with the fins, are engaged with cam grooves provided in the coupling plate, so that all the fins are coupled to the coupling plate.
- Each cam groove includes a parallel blow zone and at least one non-parallel blow zone.
- adjacent fins are arranged to be parallel with each other.
- non-parallel blow zone adjacent fins are in at least one of a state in which a space in between is narrower at an upstream end than at a downstream end and a state in which the space is wider at the upstream end than at the downstream end.
- the drive mechanism includes an allowing portion. When operation is executed to tilt the fins about the fin pivots, the allowing portion allows the coupling plate to move in an arrangement direction of the fins, while maintaining the coupling pins in the current zones in the cam grooves.

Abstract
An air-conditioning register includes a retainer, fins, a coupling plate, and a drive mechanism. The fins are tiltably supported by the retainer with fin pivots. Each fin has a coupling pin at a position displaced from the fin pivot. The coupling plate couples the fins together at the coupling pins. The drive mechanism changes the position of the coupling plate in the flowing direction. The coupling pins are engaged with cam grooves provided in the coupling plate. Each cam groove includes a parallel blow zone and at least one non-parallel blow zone. The drive mechanism includes an allowing portion. When operation is executed to tilt the fins about the fin pivots, the allowing portion allows the coupling plate to move in an arrangement direction of the fins, while maintaining the coupling pins in the current zones in the cam grooves.
Description
- The present invention relates to an air-conditioning register that blows out air-conditioning air, which is delivered from an air conditioner, through the outlet of an airflow passage.
- Vehicles have air-conditioning registers, which are configured to change the direction in which air-conditioning air from the air duct of the air conditioner is blown into the passenger compartment. One example of such an air-conditioning register includes fins and a retainer having an airflow passage, through which air-conditioning air flows. The fins are arranged in the airflow passage and tiltably supported by the retainer with fin pivots.
- Each fin has a coupling pin at a position displaced from the fin pivot. The fins are arranged parallel with each other, and the coupling pins are coupled to each other by a coupling link. This allows all the fins to be tilted while being arranged parallel with each other. Air-conditioning air is blown out from the outlet such that the air-conditioning air flows along the adjacent fins and the like, and in parallel streams through all the spaces in between and the like. The blow mode in which the air-conditioning air is blown out in this manner is referred to as a parallel blow mode.
- In recent years, a type of air-conditioning register has been proposed that is capable of blowing out air-conditioning air from the outlet in blow modes other than the parallel blow mode (non-parallel blow modes). For example, Japanese Laid-Open Patent Publication No. 2002-293133 discloses an air-conditioning register that implements a diffusion blow mode and a concentration blow mode as non-parallel blow modes.
- In the diffusion blow mode, adjacent fins are tilted such that the spaces in between at the upstream end are narrower than those at the downstream end. In this case, the air-conditioning air flows along the adjacent fins and the like through spaces in between to be diffused to a wider area toward the downstream end. A weaker flow of air-conditioning air is blown onto a wider area of the body of an occupant than in a case in which the parallel blow mode is selected.
- In the concentration blow mode, adjacent fins are tilted such that the spaces in between at the upstream end are wider than those at the downstream end. In this case, the air-conditioning air flows along adjacent fins and the like through spaces in between to be converged to reach areas that are narrowed down toward the downstream end. A stronger flow of air-conditioning air is blown onto a narrower area of the body of an occupant than in a case in which the parallel blow mode is selected.
- To implement non-parallel blow modes, the configuration of the publication employs a guide link in addition to the coupling link. The coupling link has support holes, the number of which is equal to that of the fins, and the guide link has guide holes, the number of which is equal to that of the fins. A coupling pin associated with one of the fins is received by the intersecting parts of one of the support holes and the corresponding guide hole.
- When the guide link is moved along the flow of air-conditioning air, the relative positions of the guide link and the coupling link are changed. This shifts the positions of the intersecting parts of the support holes and the guide holes to tilt the fins, so that the blow mode is switched between the parallel blow mode and the diffusion blow mode or between the parallel blow mode and the concentration blow mode.
- Further, the guide link and the coupling link are lifted or lowered, so that the fins are tilted while being maintained parallel. That is, when the parallel blow mode is selected, the direction of the parallel streams of the air-conditioning air is changed.
- When selecting the diffusion blow mode, the passenger may desire to change the part onto which the diffused air-conditioning air is blown. Also, when selecting the concentration blow mode, the passenger may desire to change the part onto which the converged air-conditioning air is blown.
- However, the air-conditioning register of Japanese Laid-Open Patent Publication No. 2002-293133, which tilts the fins by changing the positions of the intersecting parts of the support holes and the guide holes, has a limitation in increasing the patterns of tilting of the fins and thus cannot meet the above described needs.
- Accordingly, it is an objective of the present invention to provide an air-conditioning register that is capable of changing the direction of air-conditioning air not only in the parallel blow mode, but also in the non-parallel blow modes.
- To achieve the foregoing objective and in accordance with one aspect of the present invention, an air-conditioning register that includes a retainer, a plurality of fins, a coupling plate, and a drive mechanism is provided. An airflow passage is provided in the retainer. The airflow passage has an outlet at a downstream end in a flowing direction of air-conditioning air. The fins are arranged in the airflow passage and tiltably supported by the retainer with fin pivots. Each fin has a coupling pin at a position displaced from the fin pivot. The coupling plate couples the fins together at the coupling pins. The drive mechanism changes a position of the coupling plate in the flowing direction. The coupling pins, which are respectively associated with the fins, are engaged with cam grooves provided in the coupling plate, so that all the fins are coupled to the coupling plate. Each cam groove includes a parallel blow zone and at least one non-parallel blow zone. In the parallel blow zone, adjacent fins are arranged to be parallel with each other. In the non-parallel blow zone, adjacent fins are in at least one of a state in which a space in between is narrower at an upstream end than at a downstream end and a state in which the space is wider at the upstream end than at the downstream end. The drive mechanism includes an allowing portion. When operation is executed to tilt the fins about the fin pivots, the allowing portion allows the coupling plate to move in an arrangement direction of the fins, while maintaining the coupling pins in the current zones in the cam grooves.

member 61 in the state shown inFIGS. 4A, 4B , the operatingmember 61 and thepinion gear 62 integrally rotate counterclockwise as viewed inFIG. 2 . The rotation is transmitted to theguide plate 65 via therack gear 75, which meshes with thepinion gear 62. The position at which therack gear 75 meshes with thepinion gear 62 is changed so that theguide plate 65 is moved downstream as shown inFIGS. 6A and 6B . At this time, since the positions of the guide pins 22, 21 in the threeelongated holes elongated holes guide plate 65 is guided. - The movement of the
guide plate 65 is transmitted to thecoupling plate 51 via the twoguide projections 69 and the guide holes 55, so that thecoupling plate 51 is moved downstream together with theguide plate 65. Accordingly, thecam grooves cam grooves FIG. 3 ) on the upstream side. - As described above, when the coupling pins 43 are moved to the diffusion blow zones Z2, the
center fin 35 and theadjacent fins 36 are tilted such that spaces in between at the upstream end are narrower than those at the downstream end. In the first embodiment, thecenter fin 35 is maintained to be horizontal (the position parallel with theupper wall 17 and the lower wall 18).

operation knob 45 in the state shown inFIGS. 6A and 6B , the components operate, although not illustrated, in directions opposite to those in the case when upward force is applied. Theadjacent fins - In contrast, when rightward force, which is in the direction opposite to the above example, is applied to the operating
member 61 in the state shown inFIGS. 4A, 4B , the operatingmember 61 and thepinion gear 62 integrally rotate clockwise as viewed inFIG. 2 . The rotation is transmitted to theguide plate 65 via therack gear 75, so that theguide plate 65 is moved upstream as shown inFIGS. 8A and 8B . - The movement of the
guide plate 65 is transmitted to thecoupling plate 51 via the twoguide projections 69 and the guide holes 55, so that thecoupling plate 51 is moved upstream together with theguide plate 65.

operation knob 45 in the state shown inFIGS. 8A and 8B , the components operate, although not illustrated, in directions opposite to those in the case when upward force is applied. Theadjacent fins - The first embodiment as described above achieves the following advantages.
- (1) The air-conditioning register includes the
retainer 10, the multiple (three)fins coupling plate 51, and the drive mechanism DM. The coupling pins 43, which are respectively associated with therespective fins cam grooves coupling plate 51, so that all thefins FIG. 1 ). Each of thecam grooves FIG. 3 ). The drive mechanism DM includes the allowing portion (FIGS. 4A and 4B ). When theoperation knob 45 is operated to tilt thefins coupling plate 51 to move in the up-down direction, which is the arrangement direction of thefins cam grooves - Thus, the air-conditioning air A1 is allowed to be blown out in any of the parallel blow mode, the diffusion blow mode, and the concentration blow mode. The direction of the air-conditioning air A1 can be changed in any of the blow modes.
- (2) The
center cam groove 52 in the arrangement direction extends linearly in the flowing direction of the air-conditioning air A1. The twocam grooves 53, which are adjacent to and located on the opposite sides of thecenter cam groove 52 are symmetrical with respect to the center cam groove 52 (FIG. 3 ). - Thus, the two
fins 36, which are adjacent to and located on the opposite sides of thecenter fin 35 in the arrangement direction, can be tilted in mutually opposite directions. - As a result, when the coupling pins 43 are located in the parallel blow zones Z1, the
center fin 35 and theadjacent fins 36 can be arranged to be parallel with each other (FIGS. 4A and 4B ). When the coupling pins 43 are located in the diffusion blow zones Z2, the spaces between thecenter fin 35 and theadjacent fins 36 at the upstream end can be made narrower than those at the downstream end (FIGS. 6A and 6B ). When the coupling pins 43 are located in the concentration blow zones Z3, the spaces between thecenter fin 35 and theadjacent fins 36 at the upstream end can be made wider than those at the downstream end (FIGS. 8A and 8B ). - (3) The parallel blow zones Z1 are middle sections of the
cam grooves cam grooves cam grooves 52, 53 (FIG. 3 ). - Thus, the positions of the coupling pins 43 in the
respective cam grooves coupling plate 51 in the flowing direction of the air-conditioning air A1. The blow mode can be set to or switched among the diffusion blow mode, the parallel blow mode, and the concentration blow mode. - (4) The drive mechanism DM is laid on the
coupling plate 51 and includes theguide plate 65, which is moved in the flowing direction of the air-conditioning air A1 in response to rotation of the operatingmember 61. Thecoupling plate 51 has the guide holes 55, which extend in the arrangement direction of thefins 35, 36 (the up-down direction), and eachguide projection 69 on theguide plate 65 is engaged with thecorresponding guide hole 55. The guide holes 55 and theguide projections 69 constitute the allowing portion (FIGS. 1 and 3 ). - Thus, when the operating
member 61 is rotated, theguide plate 65 and thecoupling plate 51 are moved in the flowing direction to tilt thefins - When operation is executed to tilt the
fins operation knob 45, the vertical positions of theguide projections 69 in the guide holes 55 can be changed. This allows thecoupling plate 51 to be moved in the up-down direction relative to theguide plate 65, while maintaining the positions of the coupling pins 43 in the current zones in thecam grooves - (5) The operating
member 61 is rotationally supported by theshaft portion 19 of theretainer 10. Theguide plate 65 has therack gear 75. Thepinion gear 62 is arranged between the operatingmember 61 and the guide plate 65 (FIG. 2 ). Thepinion gear 62 meshes with therack gear 75 and is rotated by rotation of the operatingmember 61. - Accordingly, rotation of the operating
member 61 can be converted into linear motion and transmitted to theguide plate 65, so that theguide plate 65 can be moved in the flowing direction of the air-conditioning air A1. - Rotation of the operating
member 61 allows the position of theguide plate 65 in the flowing direction to be finely adjusted, so that the inclinations of thefins - Next, an air-conditioning register according to a second embodiment will be described with reference to
FIGS. 10 to 20B . The air-conditioning register of the second embodiment is designed to be actually installed and used in a vehicle. Unlike the first embodiment, the second embodiment is designed to include components and mechanisms that are not directly related to the characteristic features of the invention. - As shown in
FIGS. 10 to 12 , aretainer body 11 of the second embodiment is constituted by two components (anupstream retainer 12 and a downstream retainer 13), which are arranged in the direction of the flow of the air-conditioning air A1. Thedownstream retainer 13 is coupled to each of theupstream retainer 12 and thebezel 25. - As shown in
FIG. 13 , thedownstream retainer body 13 has three sets of bearingportions 31 between thebezel 25 and each of the left andright side walls portions 31 in each of theside walls fins side walls portions 31. - As shown in
FIGS. 13 and 14 , anoperation knob 45 is fitted to thecenter fin 35 to be slidable in the left-right direction (the vehicle width direction). Theoperation knob 45 is operated by an occupant to change the direction of the air-conditioning air A1 blown out from theoutlet 26. Theoperation knob 45 is allowed to tilt, together with thecenter fin 35, about the fin pivots 41 in the direction along theshort sides 27 of the outlet 26 (the up-down direction). Also, theoperation knob 45 is allowed to slide on thefin 35 to be displaced in the left-right direction (the vehicle width direction). Theoperation knob 45 has a bifurcatedfork portion 46, which extends upstream. Thefork portion 46 is configured to transmit movement (sliding motion) of theoperation knob 45 in the left-right direction (the vehicle width direction) to anupstream fin 86, which will be discussed below. - As shown in
FIGS. 12 and 14 , theupper wall 17 and thelower wall 18 have bearingportions 32, which are located between theupstream retainer 12 and thedownstream retainer 13 and substantially equally spaced apart in the left-right direction (the vehicle width direction). Multiple upstream fins are arranged in theairflow passage 14 at positions upstream of thefins outlet 26 and thelong side portions 28. - To distinguish the multiple upstream fins, the one located at the center in the left-right direction (the vehicle width direction) will be referred to as an
upstream fin 86, and the other upstream fins will be referred to asupstream fins 87. - The
upstream fins upstream fins upper wall 17 and thelower wall 18 with the bearingportions 32 at the fin pivots 88. Each of theupstream fins pin 89 at a position displaced upstream from the upper fin pivots 41. Thepins 89, which are respectively associated with theupstream fins elongated coupling rod 91, which extends in the left-right direction (the vehicle width direction). Theupstream fins pins 89, and thecoupling rod 91 constitute a parallel link mechanism, which allows theupstream fins 87 to be tilted in synchronization with the centerupstream fin 86. - Unlike the
upstream fins 87, theupstream fin 86 has atransmission shaft 92 at the downstream end. Thetransmission shaft 92 extends in the up-down direction and is held by thefork portion 46 of theoperation knob 45. Thus, when theoperation knob 45 is slid in the left-right direction (the vehicle width direction) on thecenter fin 35, force in the same direction is applied to theupstream fin 86 through thefork portion 46 and thetransmission shaft 92, so that theupstream fin 86 is tilted in the same direction about the fin pivots 88. - Each of the
side walls upstream retainer 12 has a bearingportion 33. A shut-off damper 93 is arranged in theairflow passage 14 at a position upstream of theupstream fins off damper 93 has damper pivots 94, which extend in the left-right direction (the vehicle width direction). The shut-off damper 93 is tiltably supported by theside walls portions 33 at the damper pivots 94. - As shown in
FIGS. 10 and 14 , the air-conditioning register includes a damper drive mechanism, which tilts the shut-off damper 93 to selectively open and close theairflow passage 14. The damper drive mechanism includes an operatingmember 95 and arotation transmitting portion 96. The operatingmember 95 is rotationally supported by theleft side wall 15 of theretainer 10. Therotation transmitting portion 96 is configured to transmit rotation of the operatingmember 95 to the shut-off damper 93 and is constituted by a link mechanism, a gear mechanism, and the like. - In the second embodiment, as shown in
FIG. 16 , thecam grooves coupling plate 51 each have, in addition to the parallel blow zone Z1, only the diffusion blow zone Z2 as a non-parallel blow zone. The parallel blow zones Z1 are upstream sections of thecam grooves cam grooves - The
coupling plate 51 has twoguide projections 69 at two positions spaced apart in the up-down direction. Theguide projections 69 are slightly spaced apart toward the upstream end from all thecam grooves - A
guide plate 79 constitutes part of the drive mechanism DM. Unlike theguide plate 65 of the first embodiment, theguide plate 79 does not have the horizontalguide plate portion 72. Theguide plate 79 has twoguide holes 55, which extend in the up-down direction and are spaced apart in the up-down direction. Theguide projections 69 of thecoupling plate 51 are engaged with the respective guide holes 55. - The second embodiment employs a drive mechanism DM that is different from that of the first embodiment.
- As shown in
FIGS. 11 and 13 , an operatingmember 63 is employed in place of the operatingmember 61. The operatingmember 63 includes aknob portion 63 a and ashaft portion 63 b, which extends upstream from theknob portion 63 a. The operatingmember 63 is rotationally supported by thebezel 25 at theshaft portion 63 b. - The following configuration is employed to transmit rotation of the operating
member 63 to theguide plate 79, thereby moving theguide plate 79 in the flowing direction of the air-conditioning air A1. - The
right side wall 16 has, in its downstream section,support plate portions 76 at the upper and the lower end. Thesupport plate portions 76 project rightward. Eachsupport plate portion 76 has alinear guide groove 77, which is formed in the surface that faces the othersupport plate portion 76. Theguide groove 77 is located at a position close to theside wall 16 and extends in the flowing direction of the air-conditioning air A1. Each of the upper and lowersupport plate portions 76 has a bearingportion 78 at a position displaced rightward from theguide groove 77. - A
guide plate 79 is arranged between the upper and lowersupport plate portions 76. Theguide plate 79 has rack gears 81 at the upper and lower ends. Eachrack gear 81 is formed by teeth arranged in the flowing direction of the air-conditioning air A1. Eachrack gear 81 has aguide protrusion 82, which protrudes toward the correspondingsupport plate portion 76. Eachguide protrusion 82 has an elongated shape extending in the flowing direction and is engaged with theguide groove 77 of the correspondingsupport plate portion 76 to be slidable in the flowing direction. - A
shaft 83, which extends in the up-down direction, is arranged between thesupport plate portions 76. The upper and lower ends of theshaft 83 are rotationally supported by the bearingportions 78. Pinion gears 84 are provided at upper and lower end portions of theshaft 83 to rotate integrally with theshaft 83. Eachpinion gear 84 meshes with thecorresponding rack gear 81. - The operating
member 63 and theshaft 83 are coupled to each other by a bevel gear mechanism. The bevel gear mechanism is configured to transmit rotation of theshaft portion 63 b, which extends in a direction intersecting theshaft 83, to theshaft 83. The bevel gear mechanism is constituted by the combination of adrive bevel gear 64, which is provided at the upstream end of theshaft portion 63 b of the operatingmember 63, and a drivenbevel gear 85, which is provided between the pinion gears 84 of theshaft 83 and meshes with thebevel gear 64. - As shown in
FIG. 17 , theupper wall 17 has aprojection 23 that is downstream of and adjacent to thebezel 25 and projects toward thelower wall 18. Thelower wall 18 has aprojection 23 that is downstream of and adjacent to thebezel 25 and projects toward theupper wall 17. Theprojections 23 sandwich thefins projection 23 has an upstreaminclined portion 23 a and a downstreaminclined portion 23 b. Each upstreaminclined portion 23 a constitutes an upstream part of the correspondingprojection 23. The upstreaminclined portions 23 a are inclined in the upper andlower walls projections 23 such that the space between theprojections 23 decreases toward the downstream end. Each downstreaminclined portion 23 b constitutes a downstream part of the correspondingprojection 23. The downstreaminclined portions 23 b are inclined in the upper andlower walls projections 23 such that the space between theprojections 23 increases toward the downstream end. - Other than these differences, the second embodiment is the same as the first embodiment. Thus, like or the same reference numerals are given to those components that are like or the same as the corresponding components described above in the first embodiment and detailed explanations are omitted.
- Operation of the second embodiment, which is configured as described above, will now be described.
-
FIGS. 15 and 17 illustrate the state of each component when the operatingmember 63 is located at one end in the pivoting range (movable range). At this time, the coupling pins 43, which are respectively associated with thefins FIG. 16 ), which are set in the upstream sections in thecam grooves - In the
fins coupling pin 43 is located at the same height as the correspondingfin pivot 41. Thecenter fin 35 and theadjacent fins 36 are parallel with parts of theupper wall 17 and thelower wall 18 at which theprojections 23 are not provided. The upper andlower guide projections 69 are each located substantially at the center in the up-down direction of thecorresponding guide hole 55. - Thus, the air-conditioning air A1 that has flowed into the
retainer 10 and passed through the shut-off damper 93 and theupstream fins adjacent fins fins outlet 26 in the parallel blow mode. - When upward force is applied to the
operation knob 45 in the state shown inFIGS. 15 and 17 , downward force is applied to thecoupling plate 51 via thecoupling pin 43 of thecenter fin 35 and thecam groove 52. When the positions of theguide projections 69 are shifted downward in the guide holes 55 as shown inFIGS. 18A and 18B , thecoupling plate 51 is moved downward relative to theguide plate 79 with the coupling pins 43 maintained in the parallel blow zones Z1 in thecam grooves fins fins - When downward force is applied to the
operation knob 45 in the state shown inFIGS. 15 and 17 , the components operate, although not illustrated, in directions opposite to those in the case when upward force is applied. Thefins - When clockwise force is applied to the
knob portion 63 a of the operatingmember 63 in the state shown inFIGS. 15 and 17 , the operatingmember 63 rotates in the same direction as and integrally with thedrive bevel gear 64. The rotation is transmitted to theguide plate 79 via the drivenbevel gear 85, theshaft 83, the pinion gears 84, and the rack gears 81. The position at which therack gear 81 meshes with thepinion gear 84 is changed so that theguide plate 79 is moved upstream as shown inFIGS. 19A and 19B . - The movement of the
guide plate 79 is transmitted to thecoupling plate 51 via the twoguide projections 69 and the guide holes 55, so that thecoupling plate 51 is moved upstream together with theguide plate 79. Accordingly, thecam grooves cam grooves FIG. 16 ) on the downstream side. - As described above, when the coupling pins 43 are moved to the diffusion blow zones Z2, the
center fin 35 and theadjacent fins 36 are tilted such that spaces in between at the upstream end are narrower than those at the downstream end. - The two
cam grooves 53, which are adjacent to and located on the opposite sides of thecenter cam groove 52 are symmetrical with respect to thecenter cam groove 52. Thus, the twofins 36 are tilted in mutually opposite directions. - The air-conditioning air A1 is blown out in the diffusion blow mode by flowing along the
fins adjacent fins - At this time, the
fins 36, which are on the ends in the arrangement direction, are tilted such that the space in between at the downstream end is wider than that at the upstream end. - Also, the
upper wall 17 and thelower wall 18 each have theprojection 23, and theprojections 23 have the downstreaminclined portions 23 b such that the space between theprojections 23 increases toward the downstream end. Each downstreaminclined portion 23 b is inclined in the same direction as the corresponding one of thefins 36 at the ends in the arrangement direction. Like thefins 36, the downstreaminclined portions 23 b have a function of diffusing the air-conditioning air A1. - When downward force is applied to the
operation knob 45 in the state shown inFIGS. 19A and 19B , upward force is applied to thecoupling plate 51 via thecoupling pin 43 of thecenter fin 35 and thecam groove 52. When the positions of theguide projections 69 are shifted upward in the guide holes 55 as shown inFIGS. 20A and 20B , thecoupling plate 51 is moved upward relative to theguide plate 79 with the coupling pins 43 maintained in the diffusion blow zones Z2 in thecam grooves fins adjacent fins - When upward force is applied to the
operation knob 45 in the state shown inFIGS. 19A and 19B , the components operate, although not illustrated, in directions opposite to those in the case when downward force is applied. Theadjacent fins - Thus, the second embodiment achieves the same advantages as the above described advantages (1) and (2). However, regarding the advantage (1) of the second embodiment, only the diffusion blow mode can be set as the non-parallel blow mode and change the direction of the air-conditioning air A1.
- The second embodiment achieves the following advantages (3a), (4a), and (5a) in place of the above described advantages (3), (4), and (5). The second embodiment also achieves the advantage (6) discussed below.
- (3a) The
cam grooves FIG. 16 ). - Thus, the positions of the coupling pins 43 in the
respective cam grooves coupling plate 51 in the flowing direction of the air-conditioning air A1. The blow mode can be set to or switched between the diffusion blow mode and the parallel blow mode. - (4a) The
guide plate 79 of the drive mechanism DM has the guide holes 55, which extend in the arrangement direction of thefins 35, 36 (the up-down direction), and eachguide projection 69 on thecoupling plate 51 is engaged with the corresponding guide hole 55 (FIG. 16 ). - Thus, when the operating
member 63 is rotated, theguide plate 79 and thecoupling plate 51 are moved in the flowing direction of the air-conditioning air A1 to tilt thefins - When operation is executed to tilt the
fins operation knob 45, the positions of theguide projections 69 in the guide holes 55 can be changed. This allows thecoupling plate 51 to be moved in the up-down direction relative to theguide plate 79, while maintaining the positions of the coupling pins 43 in the current zones in thecam grooves - (5a) The operating
member 63 is rotationally supported by the retainer 10 (the bezel 25). Theguide plate 79 has arack gear 81 at each of the upper and lower ends. Theshaft 83, which extends in the up-down direction and is rotationally supported, has pinion gears 84 that mesh with the rack gears 81. Theshaft portion 63 b of the operatingmember 63 and theshaft 83 are coupled to each other by the bevel gear mechanism (FIGS. 11 and 13 ). - Accordingly, rotation of the operating
member 63 can be converted into linear motion and transmitted to theguide plate 79, so that theguide plate 79 can be moved in the flowing direction of the air-conditioning air A1. - Also, rotation of the operating
member 63 allows the position of theguide plate 79 in the flowing direction to be finely adjusted, so that the inclinations of thefins - (6) The
upper wall 17 and thelower wall 18 of theretainer 10 have theprojections 23, which face each other, in the downstream sections. Theprojections 23 have the upstreaminclined portions 23 a, the space between which decreases toward the downstream end, and the downstreaminclined portions 23 b, which are located on the downstream side of the upstreaminclined portions 23 a. The space between the downstreaminclined portions 23 b increases toward the downstream end (FIGS. 19A, 19B ). - Thus, when the coupling pins 43 are in the diffusion blow zones Z2 in the
cam grooves adjacent fins inclined portions 23 b are allowed to function to diffuse the air-conditioning air A1 like thefins 36 on the opposite ends in the arrangement direction. Diffusion of the air-conditioning air A1 is more promoted than in the configuration without the downstreaminclined portions 23 b. - An air-conditioning register according to a third embodiment will now be described with reference to
FIGS. 21 to 29B focusing on differences from the first and second embodiments. - Major differences of the third embodiment from the first and second embodiments include that, as shown in
FIG. 21 , thebezel 25 is inclined such that the higher a position, the closer the position is to the upstream end in the flowing direction of the air-conditioning air A1, and that, as shown inFIG. 24B , five fins are provided. Among the five fins, the one at the center in the arrangement direction is set as a reference. The number of the fins is increased from three to five by adding twofins 37 on the opposite sides in the arrangement direction of the threefins fins 37 have the same structure as thefins fins 37 each have fin pivots 41 in the downstream section, anarm 42 extending upstream from thefin pivot 41, and acoupling pin 43 at the upstream end of thearm 42. - Since the
bezel 25 is inclined, the fivefins 35 to 37 are arranged such that the closer afin 35 to 37 is to the upper end, the closer thefin 35 to 37 is to the upstream end. The shapes of thecoupling plate 51 and theguide plate 65 are different from those of the previous embodiments. Thecoupling plate 51 has oneguide hole 55 instead of two. - As shown in
FIG. 23 , thecoupling plate 51 has five cam grooves, the number of which is the same as the number of thefins 35 to 37. Thecenter cam groove 52 in the arrangement direction extends linearly in the flowing direction of the air-conditioning air A1. Twocam grooves 53 are adjacent to and above and below thecenter cam groove 52. Thecam grooves 53 have shapes in a converse relationship on the opposite sides of thecenter cam groove 52. The twocam grooves 54, which are at the opposite ends in the arrangement direction, are located on the opposite sides of thecenter cam groove 52 and have shapes in a converse relationship. The “converse relationship” refers to a relationship in which, if one of the twocam grooves 53 is inclined relative to thecenter cam groove 52, theother cam groove 53 is inclined in the opposite direction relative to thecenter cam groove 52. - In the third embodiment, the
cam grooves 52 to 54 of thecoupling plate 51 each have, in addition to the parallel blow zone Z1, only the diffusion blow zone Z2 as a non-parallel blow zone as in the second embodiment. The parallel blow zones Z1 are upstream sections of thecam grooves 52 to 54 in the flowing direction of the air-conditioning air A1. The diffusion blow zones Z2 are set in thecam grooves 52 to 54 on the downstream side of the parallel blow zones Z1. - As shown in
FIGS. 21 and 22 , the third embodiment is the same as the first embodiment in that the operatingmember 61 is rotationally supported by thelower wall 18 of theretainer 10, that the horizontalguide plate portion 72 of theguide plate 65 has therack gear 75, that thepinion gear 62 is formed to be coaxial with the operatingmember 61, and that thepinion gear 62 meshes with therack gear 75. - Operation of the third embodiment, which is configured as described above, will now be described.
-
FIGS. 21, 24A, and 24B illustrate the state of each component when the operatingmember 61 is located at one end in the movable range. At this time, the coupling pins 43, which are respectively associated with thefins 35 to 37, are located in the parallel blow zones Z1 (seeFIG. 23 ), which are set in the upstream sections in thecam grooves 52 to 54. - The
fins 35 to 37 are tiltable about the fin pivots 41. The inclination of thefin 35, which is at the center in the arrangement direction, is determined by the position of thecoupling pin 43 in the straightcenter cam groove 52. The inclination of each of the twofins 36 is determined by the position of thecoupling pin 43 in the correspondingcam groove 53. The inclination of each of the twofins 37 is determined by the position of thecoupling pin 43 in the correspondingcam groove 54. - In the
fins 35 to 37, eachcoupling pin 43 is located at a position slightly lower than thecorresponding fin pivot 41. All thefins 35 to 37 are parallel with each other and are tilted to be higher toward the downstream end. - The upper and
lower guide projections 69 are each located at the middle section in the up-down direction in theguide hole 55. Also, each of the guide pins 21, 22 is located in the upstream section in the flowing direction of the corresponding one of theelongated holes - Thus, the air-conditioning air A1 that has flowed into the
retainer 10 flows through spaces between theadjacent fins 35 to 37 and the like in parallel streams along thefins 35 to 37 and the like and is blown out from theoutlet 26 in the parallel blow mode. - When upward force is applied to the operation knob (not shown) of the
center fin 35 in the state shown in FIGS. 24A and 24B, downward force is applied to thecoupling plate 51 via thecoupling pin 43 of thecenter fin 35 and thecam groove 52. When the positions of theguide projections 69 are shifted upward in theguide hole 55 as shown inFIGS. 25A and 25B , thecoupling plate 51 is moved downward relative to theguide plate 65 with the coupling pins 43 maintained in the parallel blow zones Z1 (refer toFIG. 23 ) in thecam grooves 52 to 54. Accordingly, the coupling pins 43 of thefins 35 to 37 are moved to positions below the fin pivots 41. Thefins 35 to 37 are parallel with each other and all tilted to be lower toward the upstream end, so that the direction of the air-conditioning air A1, which is blown out in parallel streams, is changed to a further upward direction. - When downward force is applied to the operation knob in the state shown in
FIGS. 24A and 24B , upward force is applied to thecoupling plate 51 via thecoupling pin 43 of thecenter fin 35 and thecam groove 52. When the positions of theguide projections 69 are shifted downward in theguide hole 55 as shown inFIGS. 26A and 26B , thecoupling plate 51 is moved upward relative to theguide plate 65 with the coupling pins 43 maintained in the parallel blow zones Z1 in thecam grooves 52 to 54. Accordingly, the coupling pins 43 of thefins 35 to 37 are moved to positions slightly higher than the fin pivots 41. Thefins 35 to 37 are parallel with each other and all tilted to be slightly higher toward the upstream end, so that the direction of the air-conditioning air A1, which is blown out in parallel streams, is changed from a slightly upward direction to a slightly downward direction. - When rightward force is applied to the operating
member 61 in the state shown inFIGS. 24A, 24B , the operatingmember 61 and thepinion gear 62 integrally rotate clockwise as viewed inFIG. 22 . The rotation is transmitted to theguide plate 65 via therack gear 75. The position at which therack gear 75 meshes with thepinion gear 62 is changed so that theguide plate 65 is moved upstream as shown inFIGS. 27A and 27B . At this time, since the positions of the guide pins 22, 21 in the threeelongated holes elongated holes guide plate 65 is guided. - The upstream movement of the
guide plate 65 is transmitted to thecoupling plate 51 via the twoguide projections 69 and theguide hole 55, so that thecoupling plate 51 is moved upstream together with theguide plate 65. Accordingly, thecam grooves 52 to 54 are moved upstream. The coupling pins 43 are moved in thecam grooves 52 to 54 from the parallel blow zones Z1 to the diffusion blow zones Z2 (seeFIG. 23 ) on the downstream side. - As described above, when the coupling pins 43 are moved to the diffusion blow zones Z2, the
center fin 35 and theadjacent fins 36 are tilted such that spaces in between at the upstream end are narrower than those at the downstream end. Thelower fin 36 and thefin 37 below thelower fin 36 are tilted such that the space in between at the upstream end is narrower than those at the downstream end. - The
cam grooves 53 on the opposite sides of thecenter cam groove 52 have shapes in a converse relationship on the opposite sides of thecenter cam groove 52. Thus, thefins 36, which are adjacent to and on the opposite sides of thecenter fin 35, are tilted in mutually opposite directions. Thecam grooves 54, which are at the opposite ends in the arrangement direction, have shapes in a converse relationship on the opposite sides of thecenter cam groove 52. Thus, thefins 37, which are at the opposite ends in the arrangement direction, are tilted in mutually opposite directions. - The air-conditioning air A1 is blown out in the diffusion blow mode by flowing along the
fins 35 to 37 through the spaces between theadjacent fins adjacent fins - When upward force is applied to the operation knob in the state shown in
FIGS. 27A and 27B , downward force is applied to thecoupling plate 51 via thecoupling pin 43 of thecenter fin 35 and thecam groove 52. When the positions of theguide projections 69 are shifted upward in theguide hole 55 as shown inFIGS. 28A and 28B , thecoupling plate 51 is moved downward relative to theguide plate 65 with the coupling pins 43 maintained in the diffusion blow zones Z2 in thecam grooves 52 to 54. Accordingly, the coupling pins 43 of thefins 35 to 37 are moved downward. Theadjacent fins lower fin 36 and thefin 37 below thelower fin 36 act in the same manner. The direction of the diffused air-conditioning air A1 is shifted to a further upward direction. - When downward force is applied to the operation knob in the state shown in
FIGS. 27A and 27B , upward force is applied to thecoupling plate 51 via thecoupling pin 43 of thecenter fin 35 and thecam groove 52. When the positions of theguide projections 69 are shifted downward in theguide hole 55 as shown inFIGS. 29A and 29B , thecoupling plate 51 is moved upward relative to theguide plate 65 with the coupling pins 43 maintained in the diffusion blow zones Z2 in thecam grooves 52 to 54. Accordingly, the coupling pins 43 of thefins 35 to 37 are moved upward. Theadjacent fins lower fin 36 and thefin 37 below thelower fin 36 act in the same manner. The direction of the diffused air-conditioning air A1 is shifted to a downward direction. - Thus, the third embodiment achieves the same advantages as the above described advantages (1), (3a), (4), and (5). However, as in the second embodiment, regarding the advantages (1) and (4) of the third embodiment, only the diffusion blow mode can be set as the non-parallel blow mode to change the direction of the air-conditioning air A1.
- The third embodiment achieves the following advantage (2a) in place of the above described advantage (2).
- (2a) The
center cam groove 52 in the arrangement direction extends linearly in the flowing direction of the air-conditioning air A1. The twocam grooves 53 are adjacent to and on the opposite sides of thecenter cam groove 52. Thecam grooves 53 have shapes in a converse relationship on the opposite sides of thecenter cam groove 52. Further, thecam grooves 54, which are at the opposite ends in the arrangement direction, have shapes in a converse relationship on the opposite sides of the center cam groove 52 (FIG. 23 ). - Thus, the two
fins 36, which are adjacent to and located on the opposite sides of thecenter fin 35 in the arrangement direction, can be tilted in mutually opposite directions. Also, thefins 37, which are on the opposite ends in the arrangement direction, can be tilted in mutually opposite directions. - As a result, when the coupling pins 43, which are respectively associated with the
fins 35 to 37, are located in the parallel blow zones Z1, all thefins 35 to 37 can be arranged to be parallel with each other. Also, when the coupling pins 43, which are respectively associated with thefins 35 to 37, are located in the diffusion blow zones Z2, the spaces between thefins 35 to 37 at the upstream end can be set narrower than those at the downstream end. - The above embodiments may be modified as follows.
- The
cam grooves 52 to 54 in the first to third embodiments do not necessarily need to extend through thecoupling plate 51 in the thickness direction (may have bottoms). - The guide holes 55 in the first and third embodiments do not necessarily need to extend through the
coupling plate 51 in the thickness direction (may have bottoms). - The guide holes 55 in the second embodiment do not necessarily need to extend through the
guide plate 79 in the thickness direction (may have bottoms). - The
elongated holes 67 in the first and third embodiments do not necessarily need to extend through the verticalguide plate portion 66 in the thickness direction (may have a bottom). Likewise, theelongated holes 73 do not necessarily need to extend through the horizontalguide plate portion 72 in the thickness direction (may have a bottom). - The shapes of the
cam grooves 52 to 54 may be modified such that only concentration blow zones Z3 are set in thecam grooves 52 to 54 as non-parallel blow zones. - In the first embodiment, the
upper wall 17 and thelower wall 18 may each have aprojection 23, which is formed by an upstreaminclined portion 23 a and a downstreaminclined portion 23 b as in the second embodiment. - In this case, when the coupling pins 43, which are respectively associated with the
fins cam grooves adjacent fins - The
fins 36, which are on the ends in the arrangement direction, are tilted such that the spaces in between at the downstream end are narrower than those at the upstream end. - On the other hand, the
projections 23 respectively have the upstreaminclined portions 23 a, the space between which decreases toward the downstream end. Each upstreaminclined portion 23 a is inclined in the same direction as the corresponding one of thefins 36 at the ends in the arrangement direction. Like thefins 36, the upstreaminclined portions 23 a have a function of causing the air-conditioning air A1 to converge. Thus, compared to a configuration without the upstreaminclined portions 23 a, convergence of the air-conditioning air A1 is promoted. - In contrast, when the coupling pins 43 of the
respective fins cam grooves adjacent fins - The
fins 36, which are on the ends in the arrangement direction, are tilted such that the spaces in between at the downstream end are wider than those at the upstream end. - On the other hand, the
projections 23 respectively have the downstreaminclined portions 23 b, the space between which increases toward the downstream end. Each downstreaminclined portion 23 b is inclined in the same direction as the corresponding one of thefins 36 at the ends in the arrangement direction. Like thefins 36, the downstreaminclined portions 23 b have a function of diffusing the air-conditioning air A1. Thus, compared to a configuration without the downstreaminclined portions 23 b, diffusion of the air-conditioning air A1 is promoted. - Since the diffusion and convergence of the air-conditioning air A1 are promoted, the number of the fins can be reduced. Also, the space between the
upper wall 17 and thelower wall 18 can be reduced to make theretainer 10 low-profile. - The air-conditioning register may include an even number of fins.
- The air-conditioning register may be provided at a position in the passenger compartment other than the instrument panel.
- As long as the above-described air-conditioning register uses fins to change the direction of the air-conditioning air A1 blown out into the passenger compartment from the air conditioner, the air-conditioning register may be employed in a wide range of apparatuses other than vehicles.
- The
outlet 26 of the above-described air-conditioning register may be arranged to be elongated in the vertical direction. In this case, thefins 35 to 37 extend in the up-down direction and are arranged in the left-right direction (the vehicle width direction). Theupstream fins
