Summary of the Invention

Problems to be Solved by the Invention

[0005] Incidentally, the aforementioned airflow adjustment device is configured so that the direction of the conditioned air blown out from the air outlet can be changed by rotating the operating knob vertically or sliding it horizontally. However, there is room for improvement in terms of operability when switching the conditioned air outlet state according to the user's preference. [Means for solving the problem]

[0006] The following describes various aspects of the means for solving the above problems. [Aspect 1] A register comprising: a retainer having a flow path for conditioned air and an outlet from which the conditioned air is blown out; a shut fin housed in the retainer and having a first pivot axis; and a directional fin housed in the retainer and arranged alongside the shut fin and having a second pivot axis, wherein the posture of the shut fin and the directional fin changes between at least three states: a shut state in which the conditioned air is not blown out from the outlet; a neutral state in which the conditioned air is blown straight out from the outlet; and a wind direction change state in which the conditioned air is blown diagonally out from the outlet, and the register comprising a rotating mechanism that switches between at least the three states by rotating the first pivot axis and the second pivot axis when driven.

[0007] With the above configuration, the airflow state of the air conditioner can be switched between at least the three states simply by driving the rotating mechanism. Therefore, the operability when switching the airflow state of the air conditioner can be improved.

[0008] [Aspect 2] The register according to [Aspect 1], characterized by comprising an operating unit that drives the rotation mechanism by applying manual operating force.

[0009] With the above configuration, the rotating mechanism can be driven simply by applying manual operating force to the operating part, without requiring any electrical energy. [Aspect 3] The rotating mechanism comprises a link mechanism that rotates by operation of the operating part, a cam that rotates in conjunction with the rotation of the link mechanism, a pair of first gears that rotate in conjunction with the rotation of the cam, and a pair of second gears provided on the first pivot shaft and the second pivot shaft, respectively, wherein the pair of first gears and the pair of second gears are meshed with each other, as described in [Aspect 2].

[0010] With the above configuration, the first and second pivot axes can be rotated by operating the control unit. In other words, the attitude of both the shut fin and the directional fin can be changed by operating the control unit.

[0011] [Aspect 4] The register according to [Aspect 3], characterized in that a pair of first gears are provided with pins at positions different from the pivot center, a pair of cam grooves are provided at positions different from the pivot center, the pins of the pair of first gears are slidably inserted into the pair of cam grooves, the pair of first gears rotate as the pins slide in the cam grooves in conjunction with the rotation of the cam, and the pair of cam grooves extend such that one of the pair of first gears rotates with a lag relative to the other in conjunction with the rotation of the cam.

[0012] With the above configuration, one of the pair of first gears can be rotated with a delay relative to the other by operating the control unit. Therefore, one of the shut fin and the directional fin can be rotated with a delay relative to the other by operating the control unit. [Effects of the Invention]

Embodiments for Carrying out the Invention

[0015] Hereinafter, an embodiment of the register will be described with reference to the drawings. The register is, for example, a component mounted on a vehicle. Specifically, the register is incorporated into the instrument panel of the vehicle. The register is connected to the air conditioner of the vehicle. The register blows out the conditioned air supplied from the air conditioner into the passenger compartment, which is the internal space of the vehicle. The register is configured to change the direction of the conditioned air blown into the passenger compartment or to prevent the conditioned air from being blown into the passenger compartment.

[0016] Hereinafter, the description will be based on the orthogonal coordinate system composed of the X-axis, Y-axis, and Z-axis. Also, in Figures 4 to 9, the retainer 15 described later is omitted in the drawing. <Register 11> As shown in Figure 1, the register 11 includes a main body portion 12, a rotation mechanism 13, and an operation portion 14.

[0017] <Main body portion 12> As shown in Figures 1 and 2, the main body 12 has a shape with width, depth, and height. The main body 12 is, for example, a rectangular parallelepiped. The width of the main body 12 is the length along the X-axis. The depth of the main body 12 is the length along the Y-axis. The height of the main body 12 is the length along the Z-axis. The main body 12 includes a retainer 15, a shut fin 16, a directional fin 17, and a rotating fin 18.

[0018] The retainer 15 is configured as a cylindrical shape extending along the X-axis. The retainer 15 is also configured as a rectangular cylinder, for example. The retainer 15 has a rectangular shape in the planes of the X-axis and Z-axis. The conditioned air flows through the retainer 15 in the direction of the Y-axis. The retainer 15 has a flow path 19. The flow path 19 is the space through which the conditioned air flows. The flow path 19 is the space within the retainer 15. The flow path 19 extends along the Y-axis.

[0019] As shown in Figure 2, the retainer 15 has an outlet 20. The outlet 20 is connected to the flow path 19. The outlet 20 is connected to the downstream portion of the flow path 19. The retainer 15 blows out conditioned air from the outlet 20. The outlet 20 is rectangular when viewed from the front. For example, the outlet 20 is rectangular in the planes of the X and Z axes.

[0020] As shown in Figures 1 and 2, a shut fin 16 and a directional fin 17 are rotatably housed within the retainer 15 at the outlet 20 side. Both the shut fin 16 and the directional fin 17 are rectangular plate-shaped extending along the X-axis. The shut fin 16 and the directional fin 17 are arranged almost vertically when viewed from the outlet 20 side.

[0021] The shut fin 16 and the directional fin 17 are positioned so that when they are in a position parallel to the planes of the X and Z axes (in the shut state described later), the lower end of the shut fin 16 and the upper end of the directional fin 17 overlap in the Y-axis direction, with a slight offset from each other in the Y-axis direction. The shut fin 16 is positioned slightly further from the outlet 20 than the directional fin 17 in the Y-axis direction.

[0022] At one end face in the long direction of the shut fin 16 and the directional fin 17, a first rotation shaft 21 and a second rotation shaft 22 are provided, respectively, extending along the X-axis. That is, the shut fin 16 has a first rotation shaft 21, and the directional fin 17 has a second rotation shaft 22.

[0023] As shown in Figures 1 and 4, the first pivot shaft 21 passes through the retainer 15, with its tip protruding outside the retainer 15. A shut gear 23, an example of a second gear, is provided at the tip of the first pivot shaft 21, which rotates integrally with the first pivot shaft 21. The shut gear 23 is rotatably engaged with a pivot mechanism 13 located outside the retainer 15. The shut fin 16 rotates integrally with the first pivot shaft 21, with the first pivot shaft 21 as the pivot point.

[0024] The second pivot shaft 22 passes through the retainer 15, with its tip protruding outside the retainer 15. A directional gear 24, an example of a second gear that rotates integrally with the second pivot shaft 22, is provided at the tip of the second pivot shaft 22, paired with the shut gear 23 of the first pivot shaft 21. The directional gear 24 is rotatably engaged with a pivot mechanism 13 located outside the retainer 15. The directional fin 17 rotates integrally with the second pivot shaft 22, with the second pivot shaft 22 as the pivot point.

[0025] As shown in Figures 2 and 3, a rotating fin 18 is rotatably housed within the retainer 15 at a position opposite to the outlet 20. The rotating fin 18 is configured to change the direction of the conditioned air flowing through the flow path 19 in the X-axis direction by rotating. That is, the rotating fin 18 changes the direction of the conditioned air flowing through the flow path 19 in the left-right direction.

[0026] The rotating fin 18 has a rotating shaft 25. The rotating shaft 25 is configured to rotate relative to the retainer 15. The rotating shaft 25 is rotatably mounted on the inner surfaces of both side walls in the X-axis direction of the retainer 15. The rotating shaft 25 extends along the X-axis so as to traverse the flow path 19. The rotating shaft 25 may be configured to rotate manually by user operation or to rotate automatically by a motor (not shown).

[0027] The rotating fin 18 has a plurality of rotating plates 26. The rotating plates 26 are fixed to the rotation shaft 25. For example, the plurality of rotating plates 26 are fixed to the rotation shaft 25 so as to be arranged at equal intervals in the axial direction of the rotation shaft 25. The plurality of rotating plates 26 rotate together with the rotation shaft 25. For example, the rotating plates 26 have an elliptical shape. For example, the rotating plates 26 have an elliptical shape that is a perfect circle when viewed from the axial direction of the rotation shaft 25.

[0028] The rotating plate 26 is fixed to the rotation axis 25 in an inclined position with respect to the rotation axis 25. The rotating plate 26 is fixed to the rotation axis 25 in an orientation where the central axis of the rotating plate 26 intersects with the rotation axis 25. Multiple rotating plates 26 are each fixed to the rotation axis 25 in a parallel position. The rotating plate 26 guides the conditioned air by coming into contact with the conditioned air flowing through the flow path 19. In this way, the rotating plate 26 changes the direction of the conditioned air flowing through the flow path 19.

[0029] <Rotation mechanism 13> As shown in Figures 1, 4, and 5, the rotation mechanism 13 is positioned opposite the retainer 15 in the X-axis direction. The rotation mechanism 13 includes a link mechanism 27, a cam 28, a shut-side transmission gear 29 as an example of a first gear, a directional-side transmission gear 30 as an example of a first gear, a shut-side gear 23, and a directional gear 24.

[0030] The linkage mechanism 27 includes a first link 31, a second link 32, and a third link 33. One end of a connecting shaft 34 extending along the X-axis is fixed to the base end of the first link 31. The connecting shaft 34 is rotatably supported by a support member (not shown). An operating section 14 is provided at an intermediate position on the connecting shaft 34.

[0031] The operating section 14 has a cylindrical fixed part 35 fitted to rotate integrally with the connecting shaft 34, and a rectangular plate-shaped knob 36 provided on the circumferential surface of the fixed part 35 so as to protrude radially. The operating section 14 drives the rotation mechanism 13 when manual operating force is applied. That is, the operating section 14 rotates integrally with the connecting shaft 34 when manual operating force is applied, thereby rotating the first link 31 of the link mechanism 27. The rotation mechanism 13 is located between the retainer 15 and the operating section 14 in the X-axis direction.

[0032] The tip of the first link 31 is rotatably connected to the base end of the second link 32 about an axis extending in the X-axis direction. The tip of the second link 32 is rotatably connected to the base end of the third link 33 about an axis extending in the X-axis direction. The tip of the third link 33 is fixed to the cam 28. The first link 31, the second link 32, and the third link 33 are rotatably connected in this order to form a roughly U-shape. Therefore, the link mechanism 27 rotates when the operating part 14 is operated.

[0033] The cam 28 has a rounded, roughly triangular plate shape overall. The cam 28 is positioned parallel to the planes of the Y and Z axes. In the X-axis direction, the cam 28 is positioned adjacent to the link mechanism 27, but closer to the retainer 15 than the link mechanism 27. The tip of the third link 33 is fixed to the peripheral edge of the face of the cam 28 that faces the link mechanism 27.

[0034] A pair of cam shafts 37, projecting along the X-axis, are provided approximately in the center of the face of the cam 28 opposite to the link mechanism 27. The cam 28 is rotatably supported by the pair of cam shafts 37 by bearings (not shown). The cam 28 is configured to rotate around the pair of cam shafts 37 as its pivot point. The cam 28 rotates in conjunction with the rotation of the link mechanism 27.

[0035] The cam 28 has a shut-side cam groove 38, which is an example of a cam groove, and a directional-side cam groove 39, which is an example of a cam groove, provided through it at a position different from the pair of cam shafts 37 that serve as the rotation center. Both the shut-side cam groove 38 and the directional-side cam groove 39 extend along the periphery of the cam 28 and are arranged to face each other with the pair of cam shafts 37 in between. The shut-side cam groove 38 is shorter in length than the directional-side cam groove 39.

[0036] On the opposite side of the cam 28 from the link mechanism 27, the shut-side transmission gear 29 and the directional-side transmission gear 30 are arranged in a pair. The shut-side transmission gear 29 is positioned above the directional-side transmission gear 30. Both the shut-side transmission gear 29 and the directional-side transmission gear 30 are generally shaped like fan-shaped plates. The shut-side transmission gear 29 and the directional-side transmission gear 30 are arranged parallel to the cam 28.

[0037] On the side of the shut-side transmission gear 29 opposite to the cam 28 side, a pair of shut shafts 40 are provided, projecting along the X-axis. The shut-side transmission gear 29 is rotatably supported by bearings (not shown) on the pair of shut shafts 40. The shut-side transmission gear 29 is configured to rotate around the pair of shut shafts 40 as its pivot point.

[0038] A shut pin 41, an example of a pin that protrudes along the X-axis, is provided on the cam 28 side surface of the shut-side transmission gear 29. The shut pin 41 is positioned at a location different from the rotation center of the shut-side transmission gear 29. The shut pin 41 is slidably inserted into the shut-side cam groove 38 of the cam 28.

[0039] The shut-side transmission gear 29 rotates as the shut pin 41 slides in the shut-side cam groove 38 in conjunction with the rotation of the cam 28. The shut-side transmission gear 29 meshes with the shut gear 23 of the first pivot shaft 21. The shut gear 23 rotates integrally with the first pivot shaft 21 and the shut fin 16 in conjunction with the rotation of the shut-side transmission gear 29.

[0040] On the side of the directional transmission gear 30 opposite to the cam 28 side, a pair of directional shafts 42 are provided, projecting along the X-axis. The directional transmission gear 30 is rotatably supported by bearings (not shown) on the pair of directional shafts 42. The directional transmission gear 30 is configured to rotate around the pair of directional shafts 42 as its pivot point.

[0041] A directional pin 43, an example of a pin that protrudes along the X-axis, is provided on the cam 28 side surface of the directional transmission gear 30. The directional pin 43 is positioned at a location different from the rotation center of the directional transmission gear 30. The directional pin 43 is positioned offset from the rotation center of the directional transmission gear 30. The directional pin 43 is slidably inserted into the directional cam groove 39 of the cam 28.

[0042] The directional transmission gear 30 rotates as the directional pin 43 slides in the directional cam groove 39 in conjunction with the rotation of the cam 28. The directional transmission gear 30 meshes with the directional gear 24 of the second pivot shaft 22. The directional gear 24 rotates integrally with the second pivot shaft 22 and the directional fin 17 in conjunction with the rotation of the directional transmission gear 30.

[0043] As shown in Figure 6, the shut-side cam groove 38 in the cam 28 has a shut rotation region 44 and a shut relief region 45. The shut rotation region 44 is the region in which the shut-side transmission gear 29 rotates when the shut pin 41 slides as the cam 28 rotates. The shut relief region 45 is the region in which the shut-side transmission gear 29 does not rotate even when the shut pin 41 slides as the cam 28 rotates.

[0044] The directional cam groove 39 in the cam 28 has a directional rotation region 46 and a directional relief region 47. The directional rotation region 46 is the region in which the directional transmission gear 30 rotates when the directional pin 43 slides in conjunction with the rotation of the cam 28. The directional relief region 47 is the region in which the directional transmission gear 30 does not rotate even when the directional pin 43 slides in conjunction with the rotation of the cam 28.

[0045] As the cam 28 rotates, the directional pin 43 slides in the directional rotation region 46, while the shut pin 41 slides in the shut relief region 45. As the cam 28 rotates, the shut pin 41 slides in the shut rotation region 44, while the directional pin 43 slides in the directional relief region 47. In other words, the shut-side cam groove 38 and the directional-side cam groove 39 extend such that one of the shut-side transmission gear 29 and the directional-side transmission gear 30 rotates with a lag relative to the other as the cam 28 rotates.

[0046] <State of Register 11> As shown in Figures 6 to 9, the register 11 is configured such that by operating the operating unit 14 to rotate the cam 28, the attitude of the shut fin 16 and the directional fin 17 can be changed between four states, for example: a neutral state (the state shown in Figure 6), a first wind direction change state as an example of a wind direction change state (the state shown in Figure 7), a second wind direction change state as an example of a wind direction change state (the state shown in Figure 8), and a shut state (the state shown in Figure 9).

[0047] In other words, the register 11 is configured to be switchable between the four states described above by driving the rotation mechanism 13 through the operation of the operating unit 14, thereby rotating the first rotation shaft 21 and the second rotation shaft 22 together with the shut fin 16 and the directional fin 17, respectively.

[0048] As shown in Figures 2 and 6, the neutral state is when both the shut fin 16 and the directional fin 17 are in a horizontal position, and the conditioned air is blown straight out horizontally from the outlet 20. In other words, the neutral state is when both the shut fin 16 and the directional fin 17 are located in the position shown by the dashed line in Figure 2.

[0049] As shown in Figures 2 and 7, the first airflow direction change state is when the shut fin 16 is in a horizontal position and the directional fin 17 is in a vertical position extending upward from the second rotation axis 22, and the conditioned air is blown out diagonally upward from the outlet 20. In other words, the first airflow direction change state is when the shut fin 16 is located at the position shown by the dashed line in Figure 2 and the directional fin 17 is located at the position shown by the dashed line in Figure 2.

[0050] As shown in Figures 2 and 8, the second airflow direction change state is when the shut fin 16 is in a horizontal position and the directional fin 17 is in a vertical position extending downward from the second rotation axis 22, and the conditioned air is blown out diagonally downward from the outlet 20. In other words, the second airflow direction change state is when the shut fin 16 is located in the position shown by the dashed line in Figure 2 and the directional fin 17 is located in the position shown by the solid line in Figure 2.

[0051] As shown in Figures 2 and 9, the shut state is a state in which the shut fin 16 is in a vertical position extending downward from the first rotation axis 21 and the directional fin 17 is in a vertical position extending downward from the second rotation axis 22, and no conditioned air is blown out from the outlet 20. In other words, the shut state is a state in which both the shut fin 16 and the directional fin 17 are in the position shown by the solid line in Figure 2.

[0052] <Operation of the Embodiment> As shown in Figure 6, when the register 11 is in the neutral position, the knob 36 of the operating section 14 is in a nearly horizontal position. At this time, the shut pin 41 of the shut-side transmission gear 29 is located in the shut-relief region 45 of the shut-side cam groove 38, and the directional pin 43 of the directional-side transmission gear 30 is located in the directional rotation region 46. If the knob 36 is rotated upward, for example, by 15° from this state, the cam 28 rotates counterclockwise.

[0053] As a result of the rotation of the cam 28, the directional pin 43 slides in the directional rotation region 46 and the shut pin 41 slides in the shut relief region 45. Therefore, as shown in Figure 7, the shut-side transmission gear 29 does not rotate, but the directional-side transmission gear 30 rotates counterclockwise. As a result, the directional fin 17 rotates clockwise together with the directional gear 24 and the second pivot shaft 22, resulting in the first wind direction change state.

[0054] Furthermore, when the knob 36 is rotated downward by, for example, 15° from the neutral position of the register 11 shown in Figure 6, the cam 28 rotates clockwise. As a result of this rotation of the cam 28, the directional pin 43 slides in the directional rotation region 46 and the shut pin 41 slides in the shut relief region 45. Therefore, as shown in Figure 8, the shut-side transmission gear 29 does not rotate, but the directional-side transmission gear 30 rotates clockwise. This causes the directional fin 17 to rotate counterclockwise together with the directional gear 24 and the second pivot shaft 22, resulting in the second wind direction change state.

[0055] Furthermore, when the knob 36 is rotated downward by, for example, 15° from the second wind direction change state of the register 11 shown in Figure 8, the cam 28 rotates clockwise. As a result of this rotation of the cam 28, the directional pin 43 slides in the directional relief region 47 and the shut pin 41 slides in the shut rotation region 44. Therefore, as shown in Figure 9, the directional-side transmission gear 30 does not rotate, but the shut-side transmission gear 29 rotates clockwise. As a result, the shut fin 16 rotates counterclockwise together with the shut gear 23 and the first pivot shaft 21, resulting in a shut state.

[0056] In this way, the register 11 allows both the shut fin 16 and the directional fin 17 to be rotated with a time delay by operating just one control unit 14. Therefore, the operability when switching the airflow state for the air conditioner can be improved.

[0057] <Effects of the Embodiment> According to the embodiments described in detail above, the following effects are achieved. (1) The register 11 includes a retainer 15 having a flow path 19 through which conditioned air flows and an outlet 20 from which conditioned air is blown out, a shut fin 16 housed in the retainer 15 and having a first rotation axis 21, and a directional fin 17 housed in the retainer 15 and arranged alongside the shut fin 16 and having a second rotation axis 22. The register 11 is configured such that the attitude of the shut fin 16 and the directional fin 17 changes between four states: a shut state in which conditioned air is not blown out from the outlet 20, a neutral state in which conditioned air is blown straight out from the outlet 20, a first airflow direction change state in which conditioned air is blown diagonally upward from the outlet 20, and a second airflow direction change state in which conditioned air is blown diagonally downward from the outlet 20. The register 11 has a rotating mechanism 13 that switches between the four states by rotating the first rotating shaft 21 and the second rotating shaft 22 when driven.

[0058] With the above configuration, the airflow state of the air conditioner can be switched between the four states simply by driving the rotating mechanism 13. Therefore, the operability when switching the airflow state of the air conditioner can be improved.

[0059] (2) The register 11 includes an operating unit 14 that drives the rotating mechanism 13 when manual operating force is applied. With the above configuration, the rotating mechanism 13 can be driven simply by applying manual operating force to the operating unit 14, without requiring electrical energy. Therefore, the environmental burden can be reduced compared to when the rotating mechanism 13 is driven by an electric motor or the like.

[0060] (3) In the register 11, the rotating mechanism 13 includes a link mechanism 27 that rotates when the operating part 14 is operated, a cam 28 that rotates in conjunction with the rotation of the link mechanism 27, a shut-side transmission gear 29 and a directional-side transmission gear 30 that rotate in conjunction with the rotation of the cam 28, and a shut-side gear 23 and a directional gear 24 provided on the first rotating shaft 21 and the second rotating shaft 22, respectively. The shut-side transmission gear 29 and the directional-side transmission gear 30 mesh with the shut-side gear 23 and the directional gear 24, respectively.

[0061] With the above configuration, the first pivot shaft 21 and the second pivot shaft 22 can be rotated by operating the operating unit 14. In other words, the attitude of both the shut fin 16 and the directional fin 17 can be changed by operating the operating unit 14.

[0062] (4) In the register 11, the shut-side transmission gear 29 and the directional-side transmission gear 30 are provided with a shut pin 41 and a directional pin 43 at positions different from the rotation center, respectively. The cam 28 is provided with a shut-side cam groove 38 and a directional-side cam groove 39 at positions different from the rotation center. The shut pin 41 and the directional pin 43 are slidably inserted into the shut-side cam groove 38 and the directional-side cam groove 39, respectively. The shut-side transmission gear 29 and the directional-side transmission gear 30 rotate as the cam 28 rotates, with the shut pin 41 and the directional pin 43 sliding in the shut-side cam groove 38 and the directional-side cam groove 39, respectively. The shut-side cam groove 38 and the directional-side cam groove 39 extend such that one of the shut-side transmission gear 29 and the directional-side transmission gear 30 rotates with a lag relative to the other as the cam 28 rotates.

[0063] With the above configuration, the operation of the operating unit 14 allows one of the shut-side transmission gear 29 and the directional-side transmission gear 30 to rotate with a delay relative to the other. Therefore, the operation of the operating unit 14 allows one of the shut-side fin 16 and the directional fin 17 to rotate with a delay relative to the other.

[0064] <Example of changes> The above embodiment can be implemented with the following modifications. Furthermore, the above embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0065] The rotating mechanism 13 may be driven by an electric motor. The link mechanism 27 may be omitted, and the cam 28 may be configured to rotate directly by the operation of the operating unit 14.
