Description

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

  An air conditioning register for changing the direction of air conditioning air sent from the air conditioner and blown into the passenger compartment is incorporated in the instrument panel of the vehicle. As one mode of this air conditioning register, there is one using an annular fin.

  FIG. 10 shows a schematic configuration of this type of air-conditioning register (details are not shown). This air-conditioning register includes a case 80 and a plurality of upstream fins 86 in addition to the annular fin 83. The case 80 has a cylindrical shape, and its internal space serves as a ventilation path 81 for air-conditioning air A. The downstream end of the ventilation path 81 is an air outlet 82 for air-conditioning air A.

  In this case 80, one of the two directions orthogonal to the ventilation direction of the air-conditioning air A in the ventilation path 81 (the left-right direction in FIG. 10) is the first direction, and the other is orthogonal to the paper surface. Direction) is the second direction.

  The annular fin 83 is supported so as to be tiltable in the second direction on the upstream side of the air outlet 82 in the case 80. The annular fin 83 includes a pair of fin portions 84 that extend in the first direction while being separated in the second direction, and includes a pair of end connection portions 85 that connect the ends of the fin portions 84 to each other. The annular fin 83 is elongated in the first direction than in the second direction.

  The plurality of upstream fins 86 are disposed at a plurality of locations along the first direction on the upstream side of the annular fin 83 in the case 80. Each upstream fin 86 extends in the second direction and is supported to be tiltable in the first direction.

  The air-conditioning air A flows along the upstream fins 86 and the annular fins 83 when passing through the ventilation path 81 in the case 80, and is then blown out from the air outlet 82. Therefore, the upstream fin 86 and the annular fin 83 are tilted, so that the air-conditioning air A is blown out from the outlet 82 in directions corresponding to the inclinations of the upstream fin 86 and the annular fin 83. In other words, the inclination of the upstream fins 86 and the annular fins 83 is changed, so that the blowing direction of the air-conditioning air A from the air outlet 82 is changed.

  In the air-conditioning register, as shown in FIG. 10, when the upstream fin 86 is inclined with respect to the ventilation direction, the end coupling portion 85 of the annular fin 83 causes the air-conditioning air A to flow along the upstream fin 86. It is located on the flow path and may hinder the flow of air-conditioning air A.

  Then, the air-conditioning register which tries to solve said problem by devising the shape of the end connection part 85 of the cyclic | annular fin 83 is proposed (for example, refer patent document 1). FIG. 11 shows a schematic configuration of this air-conditioning register (details are not shown). In FIG. 11, portions corresponding to those in FIG. 10 are denoted by the same reference numerals. In this air-conditioning register, the end connecting portion 85 is inclined with respect to the ventilation direction so that the interval between the two end connecting portions 85 in the annular fin 83 becomes wider toward the downstream side (lower side in FIG. 11).

  According to the air conditioning register, when the upstream fin 86 is inclined with respect to the ventilation direction as shown in FIG. 11, the end connecting portion 85 is on the flow path of the air conditioning air A that flows along the upstream fin 86. Therefore, a phenomenon in which the flow of the air-conditioning air A is hindered by the end connecting portion 85 is less likely to occur.

JP2011-148455A

  However, in the air-conditioning register of FIG. 11 described in Patent Document 1, when the upstream fin 86 is made parallel to the ventilation direction, the actual opening area of the air outlet 82 is reduced. The actual opening area is an area of a portion where the above-described components and parts are not projected on the projection plane when a plane orthogonal to the ventilation direction at the air outlet 82 of the ventilation path 81 is a projection plane. By tilting the end connecting portion 85 as described above, the area of the projected portion of the end connecting portion 85 on the projection surface is increased, and the actual opening area is reduced accordingly. As the actual opening area decreases, the ventilation resistance increases and the pressure loss increases.

  The present invention has been made in view of such circumstances, and its purpose is to suppress pressure loss caused by the end connecting portion while suppressing the end connecting portion of the annular fin from obstructing the flow of air for air conditioning. It is an object of the present invention to provide an air conditioning register that can reduce the size of the air conditioning.

In order to achieve the above object, the invention according to claim 1 is characterized in that the internal space is an air-conditioning air ventilation path, and the air-conditioning air outlet is provided at the downstream end of the ventilation path. A cylindrical case in which one of two directions orthogonal to each other among the directions orthogonal to the ventilation direction of the air-conditioning air in the ventilation path is a first direction and the other is a second direction, and the air outlet in the case And a pair of fin portions extending in the first direction in a state of being spaced apart in the second direction, and supported on the upstream side of the two directions. An annular fin provided with a pair of end connecting portions that connect the end portions, and disposed at a plurality of locations along the first direction on the upstream side of the annular fin in the case, each extending in the second direction, Supports tilting in the first direction. A plurality of upstream fins, wherein the annular fin is supported so as to be movable in the first direction with respect to the case, and the end connecting portion is provided in the ventilation path. The end coupling portion is formed in parallel with the ventilation direction of the air-conditioning air, and the upstream fin is tilted in the first direction in conjunction with the movement of the annular fin in the first direction. interlocking mechanism for retracting from the flow path of the air-conditioning air flowing along the side fins further provided, et al is that, inside the casing, the said end connecting portion inserted through a shaft to said annular fins extending in the first direction The gist is that the annular fin is supported by the shaft so as to be movable in the first direction by the shaft .

  According to said structure, when passing through the ventilation path in a case, air for an air conditioning is blown out from a blower outlet, after flowing along an upstream fin and an annular fin. Therefore, when the upstream fin is tilted in the first direction and the annular fin is tilted in the second direction, the air for air conditioning flows in a direction according to each inclination of the upstream fin and the annular fin, It is blown out from the outlet.

  According to the first aspect of the present invention, when the annular fin is tilted in the first direction, the upstream fin is tilted in the first direction in conjunction with the movement by the interlocking mechanism. Due to the movement of the annular fin and the tilting of the upstream fin, the end coupling portion retreats from the air conditioning air flow path flowing along the upstream fin. Therefore, a phenomenon in which the flow of air-conditioning air is hindered by the end connecting portion is less likely to occur.

  Further, the end connecting portion reduces the actual opening area of the air outlet when the upstream fin is parallel to the ventilation direction. The actual opening area is an area of a portion where each component or each part of the air-conditioning register is not projected on the projection plane when a plane orthogonal to the ventilation direction is used as a projection plane at the outlet of the ventilation path.

  In this respect, in the invention according to claim 1, in which the end connecting portion is formed in parallel with the ventilation direction of the air-conditioning air, the end connecting portion is connected at the projection plane more than when the end connecting portion is inclined with respect to the ventilation direction. The area of the projected part of the part is reduced. Along with this, the actual opening area increases, the ventilation resistance decreases, and the pressure loss decreases.

In addition , the annular fin spans the case, extends in the first direction, and is inserted into both end coupling portions of the annular fin. The shaft exhibits a function of guiding the movement of the annular fin in the first direction. Therefore, the annular fin is moved in the first direction by sliding on the shaft.

The invention according to claim 2 is the invention according to claim 1 , wherein the interlocking mechanism has a plurality of teeth arranged in parallel in the first direction, and the annular fin moves in the first direction. And a driven gear that is provided in one of the plurality of upstream fins and tilts in the first direction integrally with the upstream fin in a state where the drive gear is engaged. The gist is to include a gear.

  According to the above configuration, when the annular fin is moved in the first direction, the drive gear moves in the first direction along with the movement. The teeth of the driving gear change the teeth of the driven gear to be meshed, so that the driven gear is tilted in the first direction integrally with the upstream fin. In this way, the upstream fin is tilted in the first direction in conjunction with the movement of the annular fin.

The gist of the invention described in claim 3 is that, in the invention described in claim 1 or 2 , an operation knob is provided integrally with the annular fin.
According to the above configuration, when the operation knob is operated in the first direction, the annular fin provided integrally with the operation knob is also moved in the first direction. By the interlocking mechanism, the upstream fin is tilted in the first direction in conjunction with the movement.

  Further, since the operation knob is provided integrally with the annular fin, the number of parts of the air-conditioning register can be reduced as compared with the case where the operation knob is provided separately from the annular fin.

  According to the air-conditioning register of the present invention, it is possible to reduce the pressure loss caused by the end connecting portion while suppressing the end connecting portion of the annular fin from obstructing the flow of air-conditioning air.

Hereinafter, an embodiment in which the present invention is embodied in a vehicle air-conditioning register will be described with reference to FIGS.
In the following description, it is assumed that the traveling direction (forward direction) of the vehicle is the front, the backward direction is the rear, and the height direction is the vertical direction. Moreover, about the vehicle width direction (left-right direction), the left-right direction is prescribed | regulated on the basis of the case where a vehicle is seen from back.

  In the passenger compartment, an instrument panel is provided in front of the front seats (driver's seat and front passenger seat) of the vehicle, and the air-conditioning register according to the present embodiment is incorporated in the center and both sides in the vehicle width direction. ing. One of the functions of this air conditioning register is to adjust the direction of air conditioning air sent from the air conditioner and blown into the passenger compartment.

  As shown in FIGS. 1 and 5, the air-conditioning register includes a case 10, an annular fin 30, an operation knob 40, an upstream fin group, a transmission mechanism 50, a shut damper 60, and a damper drive mechanism 65. Next, the configuration of each part will be described.

<Case 10>
The case 10 is for connecting a ventilation duct (not shown) of the air conditioner and an opening (not shown) provided in the instrument panel. As shown in FIGS. 1 and 2, the retainer 11 and the bezel 12 is provided. Both the retainer 11 and the bezel 12 are formed of a cylindrical body whose both ends are open. The bezel 12 is disposed on the vehicle rear side (vehicle compartment side) of the retainer 11 and is connected to the retainer 11 by a connecting portion (not shown). The internal space of the case 10 (the retainer 11 and the bezel 12) is a flow path for air conditioning air A (hereinafter referred to as “ventilation path 20”) (see FIG. 5).

  As shown in FIGS. 1 and 3A and 3B, the bezel 12 has an air outlet 13 for air-conditioning air A at its downstream end. The blower outlet 13 has a horizontally long rectangular shape that is longer in the vehicle width direction than in the vertical direction. At the downstream end of the bezel 12, the periphery of the air outlet 13 is a frame portion 14 having a square ring shape. The frame part 14 constitutes the design surface of the air-conditioning register, and is curved so as to swell downstream.

  Here, of the directions orthogonal to the ventilation direction of the air-conditioning air A in the ventilation path 20, one of two directions orthogonal to each other is defined as a first direction and the other is defined as a second direction. In the present embodiment, the vehicle width direction is the first direction, and the vertical direction is the second direction. In the present specification, the “ventilation direction” refers to the flow direction of the air-conditioning air A before the direction is changed by the annular fin 30 and the upstream fins 44 and 45.

  The ventilation path 20 is surrounded by four wall portions of the case 10. These four wall portions include a pair of first wall portions 21 that face each other in the second direction (vertical direction), and a pair of second wall portions 22 that face each other in the first direction (vehicle width direction). Consists of.

  As shown in FIG. 2 and FIG. 3A, a bearing portion 23 is provided in each of the first wall portions 21 of the case 10 at locations away from the air outlet 13 by a certain distance to the upstream side. Here, the bearing portion 23 is a joint portion of the retainer 11 and the bezel 12 and is provided at a plurality of locations separated from each other in the first direction (vehicle width direction).

<Annular fin 30>
As shown in FIGS. 2 and 3B, the annular fin 30 is disposed in the bezel 12 and in the vicinity of the upstream side of the air outlet 13. The annular fin 30 has, as upstream fins, two plate-like fin portions 31 extending in the first direction (vehicle width direction) while being spaced apart from each other in the second direction (vertical direction). One end portions (left end portions) of the fin portions 31 in the first direction (vehicle width direction) are connected by a plate-like end connecting portion 32 having a uniform thickness. Similarly, the other end portions (right end portions) of the fin portions 31 in the first direction (vehicle width direction) are connected by a plate-like end connecting portion 33 having a uniform thickness. Both end connecting portions 32 and 33 are curved so as to swell in opposite directions with respect to the first direction (vehicle width direction). Each end connection part 32 and 33 is formed in parallel with the ventilation direction of the air A for air conditioning in the ventilation path 20,
By the pair of fin portions 31 and the pair of end connecting portions 32 and 33 described above, the annular fin 30 has an annular shape that is longer in the first direction (vehicle width direction) than in the second direction (vertical direction). The dimension of the annular fin 30 in the first direction (vehicle width direction) is set to be smaller than the dimension between both the second wall portions 22 of the case 10. This is a necessary condition for configuring the annular fin 30 to be movable in the first direction (vehicle width direction).

  Furthermore, the center part about the 1st direction (vehicle width direction) of both the fin parts 31 is connected by the plate-shaped center connection part 34 extended in a 2nd direction (up-down direction). The center connecting portion 34 functions as a portion where an operation knob 40 described later is provided, in addition to restricting the fin portions 31 from bending in the second direction (vertical direction).

  As shown in FIGS. 2 and 5, a shaft 35 extending in the first direction (vehicle width direction) is spanned between the second wall portions 22 at the downstream end portion of the case 10 (bezel 12). ing. Both end portions of the shaft 35 are attached to the second wall portions 22 so as not to move in at least the same direction. That is, the shaft 35 may be rotatably supported with respect to both the second wall portions 22 or may be locked so as not to rotate.

  The annular fin 30 is movable in the first direction (vehicle width direction) with respect to the case 10 in the pair of end connecting portions 32 and 33 and the central connecting portion 34 through which the shaft 35 is inserted, and in the second direction ( It is supported so that it can tilt in the vertical direction. More specifically, holes 36 are formed in both end connecting portions 32, 33 and the central connecting portion 34, and a shaft 35 is inserted through these holes 36.

  The shaft 35 functions as a fin support shaft for supporting the annular fin 30 (fin portion 31) so as to be tiltable in the second direction (vertical direction). Further, the shaft 35 is provided coaxially with the fin support shaft in the annular fin 30 (fin portion 31) and functions as a gear support shaft that supports the drive gear 51.

<Operation knob 40>
The operation knob 40 is integrally formed at a central portion in the second direction (vertical direction), which is a downstream portion of the central coupling portion 34. The operation knob 40 has a plate shape extending in the first direction (vehicle width direction). The operation knob 40 is disposed in parallel to both the fin portions 31 of the annular fin 30. Since the operation knob 40 is coupled to a part of the annular fin 30 (the central coupling portion 34), the operation knob 40 moves integrally with the annular fin 30. That is, the operation knob 40 can move (slide) in the first direction (vehicle width direction) along the shaft 35 and can tilt in the second direction (vertical direction) with the shaft 35 as a fulcrum.

<Upstream fin group>
The upstream fin group includes a plurality of upstream fins arranged in the vicinity of the upstream side of the annular fin 30 (fin portion 31) in the case 10. Each upstream fin is composed of a plate-like body extending in the second direction (vertical direction), and is disposed in a state of being separated from each other in parallel in the first direction (vehicle width direction). These upstream fins are composed of one upstream fin 44 positioned at the center in the first direction (vehicle width direction) and a plurality of (four) other upstream fins 45. Each of the upstream fins 44 and 45 includes a support shaft 46 extending outward in the same direction from both end surfaces in the second direction (vertical direction). The upstream fins 44 and 45 are rotatably supported by the bearing portion 23 of the case 10 (between the retainer 11 and the bezel 12) on both support shafts 46. Therefore, each of the upstream fins 44 and 45 can tilt in the first direction (vehicle width direction) with the support shaft 46 as a fulcrum.

  A notch 47 is formed in the upstream portion of each upstream fin 44, 45. A connection shaft 48 extending in the second direction (vertical direction) is provided in the notch 47 for each of the upstream fins 44 and 45. Each connecting shaft 48 is located at a location biased upstream from the support shaft 46. The connecting shaft 48 for each of the upstream fins 44 and 45 is connected to a long connecting rod 49 extending in the first direction (vehicle width direction). These upstream fins 44, 45, support shaft 46, connecting shaft 48, connecting rod 49, etc. constitute a parallel link mechanism that tilts all the upstream fins 45 in synchronization with the upstream fins 44.

<Transmission mechanism 50>
As shown in FIGS. 4 and 5, the transmission mechanism 50 transmits the movement of the operation knob 40 in the first direction (vehicle width direction) to the upstream fin 44 and tilts the upstream fin 44 in the same direction. Is a mechanism for preventing the movement of the operation knob 40 in the second direction (vertical direction) from being transmitted to the upstream fin 44, and includes a drive gear 51 and a driven gear 55. In addition, the transmission mechanism 50 tilts the upstream fins 44 and 45 in the same direction in conjunction with the movement of the annular fin 30 in the first direction (vehicle width direction), so that the end coupling portions 32 and 33 are moved upstream. It also serves as an interlocking mechanism for retracting from the flow path of the air-conditioning air A that flows along the side fins 44 and 45.

  The drive gear 51 is a plate-like body that extends in the first direction (vehicle width direction). A plurality of teeth 52 are juxtaposed in the first direction (vehicle width direction) at the upstream edge of the drive gear 51. From the drive gear 51, the bearing part 53 protrudes toward the downstream side. In the present embodiment, the bearing portions 53 are provided at two locations separated from each other in the first direction (vehicle width direction) in the drive gear 51. Furthermore, an engaging recess 54 extending toward the upstream side is formed at the downstream edge of the drive gear 51 and at the center in the first direction (vehicle width direction).

  And the drive gear 51 is arrange | positioned so that the both bearing parts 53 may be located in the both sides of the said center connection part 34 about a 1st direction (vehicle width direction). A part of the upstream side of the central connecting portion 34 is engaged with the engaging recess 54 from the downstream side, and the shaft 35 is inserted into both the bearing portions 53. With such a configuration, the drive gear 51 can tilt with respect to the annular fin 30 (operation knob 40). That is, the shaft 35 is provided coaxially with the fin support shaft in the annular fin 30 (fin portion 31) and functions as a gear support shaft that supports the drive gear 51. In this respect, the present embodiment is greatly different from a general air-conditioning register in which the drive gear is formed integrally with the operation knob. Further, with the above configuration, the movement of the annular fin 30 in the first direction is transmitted to the drive gear 51 via the central coupling portion 34 and the engagement recess 54. With this transmission, the drive gear 51 moves in the same direction as the annular fin 30 moves in the first direction (vehicle width direction).

  The driven gear 55 is made of a plate-like body having a flat fan shape, and is connected to one of the plurality of upstream fins 44, 45, here the upstream fin 44 located at the center in the first direction (vehicle width direction). Is provided. A plurality of teeth 56 are continuously formed on the outer peripheral surface of the driven gear 55 so as to be arranged in an arc shape. The driven gear 55 is located at the center of the upstream fin 44 in the second direction (vertical direction). Further, the driven gear 55 is located at a location slightly away from the downstream edge of the upstream fin 44 in the ventilation direction of the air conditioning air A in the ventilation path 20. Between the downstream edge of the upstream fin 44 and the tooth 56 of the driven gear 55, a notch 57 having a slightly larger interval in the second direction (vertical direction) than the thickness of the drive gear 51 is formed.

  The drive gear 51 enters the notch 57 (see FIG. 6) and is engaged with the driven gear 55. Here, the wall surfaces facing each other in the second direction (vertical direction) in the notch portion 57 abut against both surfaces of the drive gear 51 in the same direction, thereby restricting the tilt of the drive gear 51 in the same direction. It constitutes a tilt regulating part.

<Shut damper 60>
As shown in FIGS. 5 and 7, the shut damper 60 is for opening and closing the ventilation path 20, and is arranged on the upstream side (inside the retainer 11) with respect to the upstream fin group in the case 10. The shut damper 60 has a rectangular plate shape that is longer in the first direction (vehicle width direction) than in the second direction (vertical direction), corresponding to the surface orthogonal to the ventilation path 20.

The shut damper 60 is supported on the second wall portion 22 of the case 10 (retainer 11) by support shafts 61 protruding from both end faces in the first direction (vehicle width direction).
<Damper drive mechanism 65>
As shown in FIGS. 1 and 5, the damper drive mechanism 65 is a mechanism for opening and closing the shut damper 60, and includes an operation dial 66 and a rotation transmission unit 67. The operation dial 66 has a disk shape and is supported so as to be rotatable in the second direction (vertical direction) with respect to the case 10. A part of the operation dial 66 is exposed to the downstream side through a window portion 14 </ b> A provided in the frame portion 14 of the bezel 12. The rotation transmitting portion 67 is for transmitting the rotation of the operation dial 66 to the shut damper 60, and is provided outside the case 10 and between the operation dial 66 and the support shaft 61 of the shut damper 60. It has been. The rotation transmitting unit 67 is configured by a link mechanism, a gear mechanism, and the like.

The air conditioning register of the first embodiment is configured as described above. Next, the operation of this air conditioning register will be described.
As shown in FIG. 5 to FIG. 7, through the turning operation of the operation dial 66, the shut damper 60 is turned about both the support shafts 61, and the shut damper 60 is in the ventilation direction (first wall portion 21). , The ventilation path 20 is fully opened, and the air-conditioning air A flows through the ventilation path 20. The air-conditioning air A flows along the upstream fins 44 and 45 and the annular fin 30 and then blows out from the outlet 13. Therefore, the upstream fins 44 and 45 are tilted in the first direction (vehicle width direction), and the annular fin 30 is tilted in the second direction (vertical direction). It flows in the direction according to each inclination of 44 and 45 and the annular fin 30 (fin part 31), and is blown off from the blower outlet 13. FIG. In other words, by changing the inclination of the upstream fins 44 and 45 and the annular fin 30 (fin portion 31), the blowing direction of the air-conditioning air A from the outlet 13 is changed.

  Here, the drive gear 51 supported by the case 10 by the gear support shaft (shaft 35) has the gear support shaft (shaft 35) as a fulcrum with respect to the annular fin 30 (operation knob 40) in the second direction (up and down). The tilt is regulated by the tilt regulating unit. That is, in a state where the drive gear 51 is engaged with the driven gear 55, the drive gear 51 enters the notch 57 of the upstream fin 44. The wall surfaces 57A facing each other in the second direction (vertical direction) in the notch portion 57 are located on both sides of the drive gear 51 in the same direction and function as a tilt restricting portion. Therefore, when the drive gear 51 tries to tilt in the second direction (vertical direction), the drive gear 51 abuts against the wall surface 57A of the notch portion 57 and is prevented from tilting further. In this way, although the configuration is simple, the tilting of the drive gear 51 is restricted by the tilting restricting portion.

  On the other hand, the annular fin 30 supported on the case 10 by the fin support shaft (shaft 35) can tilt in the second direction (vertical direction) with the fin support shaft (shaft 35) as a fulcrum. Nothing is provided to transmit the tilt of the annular fin 30 to the drive gear 51. The operation knob 40 formed integrally with the central coupling portion 34 of the annular fin 30 can also tilt in the second direction (vertical direction) with the fin support shaft (shaft 35) as a fulcrum.

  Therefore, as shown in FIG. 8, when a force in the second direction (vertical direction: downward in FIG. 8) is applied to the operation knob 40 (when the operation knob 40 is operated in the second direction), the force is Then, it is transmitted to the annular fin 30 (fin portion 31) via the central coupling portion 34 provided integrally with the operation knob 40. The operation knob 40 is integrated with the annular fin 30 (fin portion 31) and tilts in the second direction (vertical direction) with the shaft 35 (fin support shaft) as a fulcrum, but the drive gear 51 tilts in the same direction. Instead, the state of meshing with the driven gear 55 is maintained.

  At this time, the teeth 52 of the drive gear 51 do not change the teeth 56 of the driven gear 55 to be engaged. Unlike a general air-conditioning register in which the drive gear is integrated with the operation knob and tilts in the second direction (vertical direction), the teeth 52 of the drive gear 51 slide with respect to the teeth 56 of the driven gear 55. Does not move. Further, at this time, the central connecting portion 34 tilts in the second direction (vertical direction) within the engaging recess 54 of the drive gear 51.

  As shown in FIG. 9, when a force in the first direction (vehicle width direction: left in FIG. 9) is applied to the operation knob 40 (when the operation knob 40 is operated in the first direction), the force Is transmitted to the annular fin 30 (fin portion 31) via the central coupling portion 34 provided integrally with the operation knob 40. At this time, the shaft 35 that extends between the second wall portions 22 of the case 10 and extends in the first direction (vehicle width direction) and is inserted into the both end coupling portions 32 and 33 of the annular fin 30 is connected to the annular fin 30. The function which guides the movement to the 1st direction (vehicle width direction) is exhibited. Therefore, the operation knob 40 is integrated with the annular fin 30 (fin portion 31) and is moved in the first direction (vehicle width direction) by sliding on the shaft 35 by the transmission of the force. Along with this movement, the center connecting portion 34 and the end connecting portions 32 and 33 change positions in the first direction (vehicle width direction) to the side where the operation knob 40 is operated.

  Further, since the central connecting portion 34 is engaged with the engagement recess 54, the force in the first direction (vehicle width direction) is applied to the operation knob 40 as described above (the operation knob 40 is the first). The force is transmitted to the drive gear 51 via the central connecting portion 34 and the engaging recess 54. By this transmission, the drive gear 51 operates the operation knob 40 in conjunction with the operation of the operation knob 40 in the first direction (vehicle width direction) (in conjunction with the movement of the annular fin 30 in the first direction). Move to the designated side.

  Along with this movement, the tooth 52 of the drive gear 51 changes the tooth 56 of the driven gear 55 to be meshed, so that the driven gear 55 is integrated with the upstream fin 44 and the support shaft 46 is used as a fulcrum. In the first direction (vehicle width direction), the operation knob 40 is tilted to the operated side. The movement of the upstream fin 44 with the support shaft 46 as a fulcrum is transmitted to the other upstream fin 45 via the connection shaft 48 and the connection rod 49. By this transmission, all the upstream fins 45 are tilted to the operated side of the operation knob 40 in synchronization with the upstream fins 44.

  In this way, the annular fin 30 is moved to the operated side of the operation knob 40 in the first direction (vehicle width direction), and the upstream fins 44 and 45 are moved in the first direction in conjunction with the movement. Tilt to (vehicle width direction). Due to the movement of the annular fin 30, the central coupling portion 34 and the end coupling portions 32, 33 are displaced to the operated side of the operation knob 40, and the end coupling portions 32, 33 are along the upstream fins 44, 45. Retreat from the flow path of the air-conditioning air A that flows through. Therefore, a phenomenon in which the flow of the air-conditioning air A is hindered by the end connecting portions 32 and 33 is less likely to occur.

  In the present embodiment, the drive gear 51 always meshes with the driven gear 55 even when an operation for tilting the annular fin 30 (fin portion 31) in the second direction (vertical direction) is performed on the operation knob 40. . Therefore, although the size of the drive gear 51 in the second direction (vertical direction) is smaller than that of a general air-conditioning register in which the drive gear tilts integrally when the same operation is performed, the drive gear 51 Always meshes with the driven gear 55.

  Moreover, the said end connection parts 32 and 33 and the drive gear 51 make the actual opening area of the blower outlet 13 small when the upstream fins 44 and 45 are made parallel to the ventilation direction. The actual opening area is an area where each component or each part of the air-conditioning register is not projected on the projection plane when a plane orthogonal to the ventilation direction at the air outlet 13 of the ventilation path 20 is used as the projection plane.

  In this respect, in the first embodiment in which the end connecting portions 32 and 33 are formed in a plate shape having a uniform thickness and are formed in parallel with the ventilation direction of the air-conditioning air A, the end connecting portions 32 and 33 are in the ventilation direction. Compared with the case where it is made to incline (patent document 1), the area of the location which the edge connection parts 32 and 33 are projected in a projection surface becomes small. Further, in the present embodiment in which the size of the drive gear 51 in the second direction (vertical direction) is small, the drive gear 51 on the projection plane is larger than a general air conditioning register in which the drive gear is tilted integrally with the operation knob. The area of the projected area becomes smaller. For these reasons, the actual opening area increases, the ventilation resistance decreases, and the pressure loss decreases.

  In addition, through the turning operation of the operation dial 66, the shut damper 60 is turned with the support shaft 61 as a fulcrum, and the shut damper 60 is inclined with respect to the ventilation direction (the first wall portion 21) to be in the first wall. When brought into contact with the portion 21, the ventilation path 20 is closed. The flow of the air-conditioning air A in the ventilation path 20 is blocked, and the blowing of the air-conditioning air A from the air outlet 13 is stopped.

According to the embodiment described in detail above, the following effects can be obtained.
(1) The annular fin 30 is supported so as to be movable in the first direction (vehicle width direction) with respect to the case 10. An interlocking mechanism (transmission mechanism 50) that tilts the upstream fins 44 and 45 in the same direction in conjunction with the movement of the annular fin 30 in the first direction (vehicle width direction) is provided.

  Therefore, the upstream fins 44 and 45 are tilted in the first direction (vehicle width direction) by the interlocking mechanism (transmission mechanism 50) in conjunction with the movement of the annular fin 30 in the first direction (vehicle width direction). The end connecting portions 32 and 33 can be retracted from the flow path of the air-conditioning air A flowing along the upstream fins 44 and 45. As a result, it is possible to suppress the end connecting portions 32 and 33 of the annular fin 30 from obstructing the flow of the air-conditioning air A.

  (2) Although related to (1) above, the upstream fin 44 is tilted in conjunction with the movement of the annular fin 30 by the interlocking mechanism (transmission mechanism 50). Due to the movement of the annular fin 30, the positions of the end connecting portions 32 and 33 and the central connecting portion 34 in the first direction (vehicle width direction) are changed.

  Therefore, from the downstream side of the air conditioning register, it is difficult to see the upstream fins 44 and 45 located in the case 10 and upstream from the annular fin 30, but the end coupling parts 32 and 33 and the central coupling part 34 are seen. Thus, it is possible to easily grasp the blowing direction of the air-conditioning air A in the first direction (vehicle width direction).

(3) The end connecting portions 32 and 33 are formed in parallel with the direction of ventilation of the air-conditioning air A in the ventilation path 20.
Therefore, the area of the projected portion of the end coupling portions 32 and 33 on the projection surface can be made smaller than when the end coupling portion 85 is inclined with respect to the ventilation direction (Patent Document 1). Accordingly, the actual opening area can be increased, the ventilation resistance can be reduced, and the pressure loss can be reduced.

  (4) Between the second wall portions 22 in the case 10, a shaft 35 extending in the first direction (vehicle width direction) and inserted into both end coupling portions 32 and 33 of the annular fin 30 is bridged. The annular fin 30 is supported by the shaft 35 so as to be movable in the first direction with respect to the case 10.

  Therefore, the shaft 35 can function as a guide. By sliding on the shaft 35, the annular fin 30 can be moved in the first direction (vehicle width direction).

(5) As the interlocking mechanism, a mechanism provided with the drive gear 51 and the driven gear 55 is used.
Therefore, the drive gear 51 and the driven gear 55 cause the upstream fin 44 to tilt in the first direction (vehicle width direction) in conjunction with the movement of the annular fin 30, and the end coupling portions 32 and 33 are connected to the upstream fin. The effect (1) can be obtained by retracting from the flow path of the air-conditioning air A flowing along the lines 44 and 45.

  (6) The operation knob 40 is formed integrally with the annular fin 30 at the central connecting portion 34. Such a configuration is possible only when the annular fin 30 is integrated with the operation knob 40 and moved in the first direction (vehicle width direction) with respect to the case 10. When the annular fin 30 cannot move in the first direction (vehicle width direction) with respect to the case 10 and only the operation knob 40 moves in the first direction (vehicle width direction), the operation knob 40 is defined as the annular fin 30. It must be constituted by a separate member.

Therefore, the annular fin 30 can be moved in the same direction by operating the operation knob 40 in the first direction (vehicle width direction).
Further, the number of parts can be reduced as compared with the case where the operation knob 40 is configured by a member different from the annular fin 30.

Note that the present invention can be embodied in another embodiment described below.
<About the support mode of the annular fin 30>
As an aspect for supporting the annular fin 30 on the case 10 so as to be movable in the first direction, the annular fin 30 is fixed to the shaft 35, and the annular fin 30 on the shaft 35 is in the first direction (vehicle width direction) with respect to the case 10. ) May be movably supported.

<About interlocking mechanism>
The interlocking mechanism tilts the upstream fins 44 and 45 in the same direction in conjunction with the movement of the annular fin 30 in the first direction, so that the end coupling portions 32 and 33 are moved along the upstream fins 44 and 45. It may be changed to a configuration different from that of the above-described embodiment on condition that the air-conditioning air A is retreated from the flow path.
