Description

  The present invention relates to an air conditioning register that is used as an air outlet of an air conditioner or the like and adjusts the direction of air blown into a room.

  In the passenger compartment, an instrument panel is disposed in front of the front seat. Air outlets are opened at both ends and the center of the instrument panel in the vehicle width direction. These air outlets incorporate air conditioning registers for changing the direction of air blow-out from the air conditioner or the like.

  As this air-conditioning register, one having a retainer, a fin group and a connecting rod is generally used. The retainer is formed of a cylindrical body that has an internal space as a ventilation path and has a rectangular opening at the downstream end. The fin group includes a plurality of fins arranged in the retainer, for example, in the vehicle width direction and arranged in a state of being separated from each other in the vertical direction. Each fin is supported by the left and right wall portions of the retainer so as to be tiltable on support shafts provided on both sides in the vehicle width direction. The connecting rod connects a connecting shaft provided at a location different from the support shaft of each fin, and transmits the tilt of one of the fins to the other fin. By this transmission, the plurality of fins tilt in a synchronized state.

  By the way, as for the air-conditioning register, there is a tendency for the retainer opening to have a horizontally long rectangular shape in order to secure an installation space for other devices arranged in the instrument panel. In this air conditioning register, among the four wall portions around the ventilation path of the retainer, the one including the short side of the opening is the first wall portion, and the one including the long side is the second wall portion. The fin group includes a pair of end fins located at both ends in the arrangement direction and an intermediate fin located between the both end fins. Each of the both-end fins and the intermediate fin has support shafts on both sides in the direction along the long side, and is supported by the first wall portion so as to be tiltable on these support shafts.

Here, in order to improve the directivity of the air blown from the opening at the downstream end of the retainer, it is desirable to tilt the end fin and the intermediate fin while maintaining a parallel relationship.
On the other hand, in order to ensure an air flow path between adjacent fins, the end fins are preferably tilted at a location close to the second wall portion of the retainer.

  From this point of view, the opening at the downstream end of the retainer has a horizontally long rectangular shape, but the retainer is made larger than the opening in the direction along the short side (substantially up and down direction) immediately upstream of the opening, There is also an air-conditioning register that secures a tilting area of the end fin. However, with this air-conditioning register, although the design is improved, it is difficult to secure a sufficient installation space for other devices in the instrument panel.

Thus, various attempts have been made to improve directivity without increasing the retainer by devising a mechanism for transmitting the tilt of the intermediate fin to the fins at both ends.
One of them is an air-conditioning register described in Patent Document 1.

  FIGS. 13A to 13C show a state in which the intermediate fin 83 and upper and lower end fins 81 and 82 thereof are parallel to the second wall portions 85 and 86 in the air conditioning register. In this state, as shown in FIG. 13B, the second straight link 89 overlaps both end surfaces of the end fin 82. As shown in FIG. 13C, the first straight link 87 overlaps both end surfaces of the end fin 81. Further, the U-shaped link 91 overlaps both end surfaces of the end fin 82. As shown in FIG. 13B, the upstream shaft 83 </ b> A of the intermediate fin 83 is located at the lower end of the hole 92 </ b> P of the second connecting rod 92. As shown in FIG. 13C, the shaft 83D of the intermediate fin 83 is located at the upper end of the hole 88P of the first connecting rod 88.

  14 (A) to 14 (C) show a state in which the intermediate fin 83 is tilted from the above state to the side (lower side) where the upstream end of the intermediate fin 83 moves away from the second wall portion 85 of the retainer 84. Show. With this tilting, when the upstream shaft 83A of the intermediate fin 83 moves in the same direction, the second connecting rod 92 is also pushed and moved in the same direction. Then, as shown in FIG. 14B, the upstream shaft 81A of the end fin 81 connected to the bearing 92A of the second connecting rod 92 is pulled in the same direction (downward). The end fin 81 tilts in the same direction (downward) about the downstream shaft 81B. That is, the upstream end portion of the end fin 81 tilts to the side (lower side) away from the second wall portion 85 of the retainer 84.

  As shown in FIG. 14B, the shaft 89A of the second straight link 89 connected to the bearing portion 92B of the second connecting rod 92 is also pushed and moved in the same direction (downward). This movement is also transmitted to the end fin 82 via the bearing portion 89B of the second straight link 89 and the downstream shaft 82B connected to the bearing portion 89B. By this transmission, the downstream end portion of the end fin 82 tilts toward the side (upper side) away from the second wall portion 86 below the retainer 84 around the upstream shaft 82A of the end fin 82. As described above, when the intermediate fin 83 tilts toward the side (downward) away from the upper second wall 85 of the retainer 84, the end fins 81 and 82 are also synchronized with the intermediate fin 83. It tilts to the same side as the intermediate fin 83 while maintaining a parallel state.

  Further, when the intermediate fin 83 tilts as described above, the shaft 83D at the tip of the arm 83C also moves in the same direction (downward) as shown in FIG. Along with this movement, the shaft 83D of the intermediate fin 83 moves along the hole 88P of the first connecting rod 88. That is, until the tilting of the intermediate fin 83 is completed, the first connecting rod 88 and the first straight link 87 and the U-shaped link 91 connected to the first connecting rod 88 are connected to the shaft 83D of the intermediate fin 83. The driving force due to the movement of is not transmitted. Therefore, as shown in FIG. 14C, the first connecting rod 88, the first straight link 87, and the U-shaped link 91 during the tilting are in the same state as in FIG. The two walls 85 and 86 are maintained in parallel.

  When the intermediate fin 83 is tilted from the state shown in FIGS. 13A to 13C to the side (upper side) in which the upstream end is away from the lower second wall 86 of the retainer 84. Each part of the air-conditioning register performs the reverse operation to that described above.

JP 2009-241637 A

  However, according to the air-conditioning register described in Patent Document 1, the directivity can be improved without enlarging the retainer 84 in the direction along the short side (substantially up and down), but the number of parts is reduced. In many cases, the structure becomes complicated.

  The present invention has been made in view of such circumstances, and an object of the present invention is to realize an air conditioning register that can improve directivity without increasing the size of the retainer with a simple structure.

In order to achieve the above-mentioned object, the invention according to claim 1 is a cylindrical body having an internal space as a ventilation path and having a rectangular opening at the downstream end, and the cylindrical body is provided around the ventilation path. Of the four wall portions including the short side of the opening is a first wall portion, and the retainer including the long side is a second wall portion;
The retainer includes three fins extending in the direction along the long side and arranged in a state of being separated from each other in the direction along the short side, and the fins located at both ends in the arrangement direction are a pair of end fins. The fin located between the fins at both ends is a single intermediate fin, and the intermediate fin and the end fin are respectively the first wall portions on the support shafts provided on both sides in the direction along the long side. A connecting rod that connects a group of fins supported so as to be tiltable to a connecting shaft provided on each of the intermediate fin and the end fin, and transmits the tilt of the intermediate fin about the support shaft to the end fin. An air-conditioning register that extends in a direction along the short side in the first wall portion, and that allows movement in the same direction of the support shaft in the end fin; and A cam member that is provided so as to be integrally tiltable with the support shaft of the inter-fin, and contacts the support shaft of the end fin from the intermediate fin side, and the support shaft with which the cam member is contacted, And a restricting portion that restricts the movement of the cam member toward the second wall portion with respect to the position, and the abutting position of the cam member with respect to the support shaft of the end fin changes as the cam member tilts. Thus, the position of the support shaft in the movement allowance portion is changed, and the support shaft of the end fin is provided at an end portion on the upstream side of the end fin, and the cam member is When the end fin on the downstream side of the fin is tilted toward the side approaching the second wall portion, the movement allowing portion abuts on the support shaft at a position away from the second wall portion, and the end Whether the downstream end of the fin is the second wall When the end fins are then tilted away side, and summarized in that abuts against the shaft at a point close to the second wall portion about the movement permitting part.

  According to said structure, in an air-conditioning register | resistor, each of an intermediate | middle fin and an end fin can tilt about a spindle. In addition, the support shaft of the end fin is allowed to move in the direction along the short side of the opening by the movement allowing portion provided on the first wall portion.

  Here, the connecting shaft provided in each of the intermediate fin and the end fin is connected by a connecting rod. Further, a cam member provided so as to be integrally tiltable with the support shaft of the intermediate fin is in contact with the support shaft of the end fin from the side of the intermediate fin. Further, the restricting portion restricts the support shaft with which the cam member is abutted from moving to the second wall portion side from the abutting position.

  Therefore, the position of the end fin in the movement allowing portion and the inclination of the end fin are determined by the connection using the connecting rod, the contact of the cam member, and the restriction of the restriction portion. As long as the intermediate fin is not tilted, the end fin spindle is held in its determined position and the end fin is held in its determined tilt.

  Therefore, the air flowing through the ventilation path blows out from the opening after passing through the flow path between adjacent fins. The direction of the air is determined by the fins when passing through the flow path. In the case where the fins are parallel to the second wall portion, the air flows between the adjacent fins in parallel to the second wall portion. That is, air flows between adjacent fins while maintaining the direction upstream of the fin group, and blows out in parallel to the second wall portion from the opening.

  When the intermediate fin is tilted about the support shaft, the tilt is transmitted to the other end fins via the connecting shaft and the connecting rod. Further, the cam member abuts against the support shaft of the end fin and the regulation portion is regulated regardless of the tilt of the intermediate fin. The end fin is tilted in the same direction as the intermediate fin in conjunction with the intermediate fin with the support shaft whose position is determined as described above as a fulcrum. Therefore, the direction of the air flowing through the ventilation path is changed in the process of flowing through the flow path between the fins tilted as described above. And air blows out from the opening in the changed direction. Since the end fin is tilted in the same direction as the intermediate fin in conjunction with the intermediate fin as described above, it is possible to blow out air accurately in the target direction (to ensure good directivity). is there.

  In addition, as described above, since the support shaft of the end fin is movable within the movement allowing portion extending in the direction along the short side, by moving the support shaft closer to or away from the second wall portion, It becomes possible to ensure the operation area | region of the end fin between an end fin and a 2nd wall part, and it is not necessary to enlarge a retainer to the direction along a short side.

Opening of the downstream end of the re retainer is not a rectangular shape, a space being arranged fins is narrow in the arrangement direction thereof. However, according to the above configuration, the number of fins is set to three, which is the minimum number that can be taken for wind direction adjustment, so that the space (flow path) between adjacent fins is secured while ensuring the wind direction adjustment function. It is possible to increase the size efficiently.
Further, each end fin tilts with a support shaft provided at the end on the upstream side as a fulcrum. Further, the support shaft is movable along the movement allowing portion.
When the end fin on the downstream side of the end fin is tilted toward the side closer to the second wall portion, the cam member abuts on the support shaft at a position away from the second wall portion with respect to the movement allowing portion. Therefore, the end fin is in an inclined state in which the downstream end and the upstream support shaft are greatly separated in the direction along the short side. In this case, the downstream end approaches the second wall, The end portion on the side is in an inclined state away from the second wall portion.
Further, when the end fin is tilted to the side where the downstream end of the end fin moves away from the second wall portion, the cam member comes into contact with the support shaft at a position approaching the second wall portion with respect to the movement allowing portion. Therefore, the end fin is inclined so that the downstream end and the upstream support shaft are greatly separated in the direction along the short side. In this case, the downstream end is separated from the second wall, The side end portion is in an inclined state approaching the second wall portion.
The invention according to claim 2 is formed of a cylindrical body having an internal space as a ventilation path and having a rectangular opening at a downstream end, and the opening of the four walls around the ventilation path of the cylindrical body. A retainer that includes the short side as the first wall portion, and a retainer that includes the long side as the second wall portion, and a direction extending along the long side in the retainer, and along the short side The fins located at both ends in the arrangement direction are a pair of end fins, the fins located between the fins at both ends are intermediate fins, and the first wall An air-conditioning register comprising a fin group supported to be tiltable by a support shaft relative to a portion, and a connecting rod that connects the fins with a connecting shaft provided upstream of each support shaft of the fin, The support shaft of the intermediate fin has the end fin A cam member abutting on the shaft is provided so as to be integrally tiltable, and a movement allowing portion for allowing the support shaft of the end fin to move in a direction along the short side is formed on the first wall portion, The support shaft of the end fin against which the cam member is in contact is restricted from moving toward the second wall by the restricting portion, and the cam member with respect to the support shaft of the end fin as the cam member tilts. The gist is that the position of the support shaft of the end fin is changed in the movement-permitting portion by changing the abutting location.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, when the intermediate fin is made parallel to the second wall portion, the cam member has a second end on the downstream side. The end fin is made parallel to the second wall portion by abutting on the support shaft of the end fin approaching the wall portion at a location approaching the second wall portion with respect to the movement allowing portion. It is a summary.

  When the intermediate fin is made parallel to the second wall portion, the downstream end portion of the end fin is brought closer to the second wall portion, and the cam member is moved relative to the support shaft of the end fin with respect to the movement allowing portion. 2 Abuts at a location approaching the wall. Therefore, in addition to the intermediate fins, the end fins are parallel to or close to the second wall portion. The air flows in parallel to the second wall portion by flowing along the fins between the adjacent fins. That is, air flows through the flow path between adjacent fins while maintaining the direction upstream of the fin group. And air blows off in parallel with the 2nd wall part from the opening of the downstream end of a retainer.

The invention according to claim 4 is the invention according to any one of claims 1 to 3 , wherein the restricting portion for each end fin is provided on an inner wall surface of the retainer and is downstream of the end fin. A downstream end abutted portion with which an end portion on the side abuts, and a support shaft provided at an end portion on the second wall portion side of the movement allowing portion and with which the support shaft of the end fin contacts When the end fin on the downstream side of the end fin is tilted to the side away from the second wall, the movement of the support shaft at the support contacted portion. On the other hand, when the end fin is tilted toward the side where the downstream end of the end fin approaches the second wall portion, the downstream end contacted portion restricts the movement of the support shaft. The main point is that

  According to the above configuration, when the end fin on the downstream side of the end fin is tilted to the side away from the second wall portion, the end of the end fin is provided on the inner wall surface of the retainer. Although it leaves | separates from a part, the spindle of an end fin contact | abuts to the spindle contact part provided in the edge part by the side of the 2nd wall part of a movement permissible part. By this contact, the support shaft of the end fin is restricted from moving further to the second wall side.

  Further, when the end fin is tilted to the side where the downstream end portion of the end fin approaches the second wall portion, the support shaft abutting portion of the end portion of the movement allowing portion on the second wall portion side is supported. However, the downstream end is in contact with the downstream end contact portion. By this contact, the support shaft of the end fin is restricted from moving further to the second wall side.

  Thus, when the end fin tilts to the side where the downstream end is away from the second wall, and when the end fin tilts to the side where the end approaches the second wall, that is, the end Depending on the tilting direction of the fin, the type of the restricting portion (contacted portion) that restricts the movement of the support shaft is switched between the downstream end contacted portion and the support shaft contacted portion.

The invention according to claim 5 is the invention according to any one of claims 1 to 3 , wherein the cam member is provided with a guide hole through which the support shaft of each end fin is inserted. The cam member is in contact with the support shaft of the end fin from the intermediate fin side on the inner wall surface of the guide hole far from the second wall portion, and the cam member is formed on the guide hole. Of these, the inner wall surface closer to the second wall portion is used as the restricting portion, and the support shaft with which the inner wall surface farther from the second wall portion is in contact with the second wall than the contact position. The gist is to restrict the movement to the part side.

  According to said structure, with respect to the spindle inserted in the guide hole of the cam member, the inner wall surface of the guide hole that is far from the second wall portion is abutted from the intermediate fin side. In addition, the support shaft with which the inner wall surface on the side far from the second wall portion is in contact with the second wall portion of the guide hole moves to the second wall portion side from the contact position. It is regulated by the inner wall surface (regulator) on the near side.

  Therefore, due to the contact of the cam member (the inner wall surface of the guide hole that is far from the second wall portion) with the support shaft of the end fin and the restriction portion (the inner wall surface of the guide hole that is closer to the second wall portion) The position and the inclination of the end fin are determined by the restriction and the connection using the connecting rod in the movement allowable portion of the support shaft of the end fin.

  According to the air-conditioning register of the present invention, the directivity can be improved with a simple structure without increasing the retainer.

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. Also, the left and right are defined based on the case where the vehicle is viewed from behind.

  As shown in FIG. 1, in the passenger compartment, an instrument panel 11 is provided in front of the driver's seat and front passenger seat of the vehicle, and a center cluster 12 is provided in the center in the vehicle width direction (left-right direction in FIG. 1). It has been. A display unit 13 of a display device in the navigation system is incorporated in the upper part of the center cluster 12. The display unit 13 is located obliquely left front of the steering wheel (steering wheel) 14 of the steering device.

  A pair of air-conditioning registers 15 are assembled in the vehicle width direction above the center cluster 12 and directly above the display unit 13. One of the functions of these air conditioning registers 15 is to adjust the direction (wind direction) of the air sent from the air conditioner and blown into the passenger compartment.

  The reason why the air-conditioning registers 15 are arranged at the above-mentioned locations is because the following phenomenon occurs if they are arranged on both sides of the display unit 13 (both sides in the vehicle width direction). (I) The air blown from the right air-conditioning register 15 directly hits the driver's arm holding the handle 14, causing the driver to feel bothered. (Ii) When the air flow is obstructed by the driver's arm, the air blown out from the right air-conditioning register 15 is less likely to circulate in the passenger compartment.

  On the other hand, as shown by a two-dot chain line in FIG. 1, when a high air conditioning register 15 is used, the height of the instrument panel 11 is accordingly increased as indicated by a two-dot chain line in FIG. 1. It becomes high, it becomes difficult to obtain a feeling of opening, and there is a risk of causing the occupant to feel a feeling of pressure or a feeling of obstruction.

  Therefore, in the present embodiment, as shown by the solid line in FIG. 1, a thin and low-profile air conditioning register 15 is used. Accordingly, as shown by a solid line in FIG. 1, the height of the instrument panel 11 including the center cluster 12 is kept low.

  Both the air-conditioning registers 15 have substantially the same configuration. As shown in FIGS. 2 and 3, each air conditioning register 15 includes a retainer 20, a downstream fin group 40, a tilt transmission mechanism 50, and an upstream fin group 70. Next, the configuration of each part will be described.

<Retainer 20>
The retainer 20 is for connecting a ventilation duct (not shown) of the air conditioner and an opening (not shown) provided in the center cluster 12, and is divided into an upstream member 21 and a downstream member 22. . Each of the upstream member 21 and the downstream member 22 is formed of a substantially rectangular cylindrical body having both ends opened, arranged in series, and connected to each other by a connecting means (not shown). The internal space of these upstream side member 21 and downstream side member 22 is an air flow path (hereinafter referred to as “ventilation path 23”).

  As shown in FIG. 7, the upstream opening 21 </ b> A in the upstream member 21 constitutes an air inlet from the ventilation duct. The opening 21 </ b> A has the same shape as the cross section orthogonal to the ventilation path 23, and has a horizontally long rectangular shape.

  The downstream member 22 has a bezel 22A at its downstream end. The bezel 22A constitutes the design surface of the air-conditioning register 15, and is inclined so as to move away from the driver's seat and the passenger seat toward the upper side, and has a horizontally long opening 24. As shown in FIG. 2, the opening 24 constitutes a substantial outlet of the air conditioning register 15. Here, in order to distinguish each side of the opening 24, the side extending in the vertical direction is referred to as “short side A”, and the side extending in the horizontal direction is referred to as “long side B”.

  The ventilation path 23 is surrounded by the four walls of the retainer 20. In order to distinguish these four wall portions, as shown in FIGS. 6 and 7, those corresponding to the short side A of the opening 24 are referred to as first wall portions 26 and 27 and correspond to the long side B. Is referred to as second wall portions 28 and 29. In the present embodiment in which the cross section orthogonal to the ventilation path 23 forms a horizontally long rectangular shape, the wall portions facing each other in the vehicle width direction (left-right direction) become the first wall portions 26, 27, and the wall portions facing each other in the up-down direction. Becomes the second wall portions 28 and 29.

  In a state where the upstream member 21 and the downstream member 22 are connected, the downstream end surface of the upstream member 21 and the upstream end surface of the downstream member 22 are joined. A bearing portion 31 is provided in the joint portion of each first wall portion 26, 27 and in the central portion in the vertical direction (see FIG. 5). Each of the first wall portions 26 and 27 is provided with a pair of upper and lower long holes 51 and 52, respectively. These long holes 51 and 52 will be described later.

<Downstream fin group 40>
The downstream fin group 40 includes three downstream fins extending in the direction along the long side B (vehicle width direction) in the retainer 20 and in the vicinity of the upstream side of the opening 24. The downstream fin group 40 and the downstream fin correspond to the fin group and the fin in the claims, respectively. Each of these downstream fins is formed in a flat and narrow shape having a predetermined width in the direction along the ventilation path 23, and is arranged in a state of being separated from each other in the direction along the short side A (substantially up and down direction). Yes.

  Here, in order to distinguish the three downstream fins, the one located at the upper end in the arrangement direction is referred to as an end fin 41, and the one located at the lower end is referred to as an end fin 42. Further, the one located between the two end fins 41 and 42 is referred to as an intermediate fin 43. The upper end fin 41 is disposed at a location close to the upper second wall portion 28. Further, the lower end fin 42 is disposed at a location close to the lower second wall portion 29.

  As shown in FIG. 4, with respect to the intermediate fin 43, support shafts 45 are provided on both end surfaces in the direction along the long side B. Both the support shafts 45 are provided in the intermediate portion of the end face in the direction along the ventilation path 23. And each spindle 45 is supported by the said bearing part 31 so that rotation with respect to the 1st wall parts 26 and 27 is possible (refer FIGS. 5-7). The intermediate fin 43 can tilt in the direction along the short side A (substantially up and down direction) with both the support shafts 45 as fulcrums.

  Further, with respect to the upper end fin 41, support shafts 46 are provided on both end faces in the direction along the long side B thereof. The two support shafts 46 are provided at the upstream end of the end fin 41 in the direction along the ventilation path 23 and are engaged with the long hole 51 described above. Therefore, the end fin 41 can tilt in the direction along the short side A (substantially up and down direction) with both the support shafts 46 as fulcrums.

  Similarly, support shafts 47 are provided on both end surfaces of the lower end fin 42 in the direction along the long side B thereof. The both support shafts 47 are provided at the upstream end portion of the end fin 42 in the direction along the ventilation path 23 and are engaged with the long hole 52 described above. Therefore, the end fins 42 can tilt in the direction along the short side A (substantially up and down direction) with both the support shafts 47 as fulcrums.

<Tilt transmission mechanism 50>
As shown in FIGS. 4 and 5, the tilt transmission mechanism 50 transmits the tilt of the intermediate fin 43 to the both-end fins 41 and 42, and synchronizes with the intermediate fin 43 to make the both-end fins 41 and 42 the same as the intermediate fin 43. It is for tilting in the direction, and is provided on both sides in the direction along the long side B.

  Each tilt transmission mechanism 50 includes the long holes 51 and 52 for the first wall portions 26 and 27 described above as movement allowance portions. The long holes 51 and 52 for each of the first wall portions 26 and 27 are provided at the joint portions of the upstream side member 21 and the downstream side member 22 and close to the upper and lower second wall portions 28 and 29. ing. Both the upper and lower long holes 51 and 52 for each of the first wall portions 26 and 27 extend in the direction along the short side A. Here, the “direction along the short side A” includes not only the same direction as the short side A but also a direction intersecting with the short side A with a slight inclination. In the present embodiment, the upper long hole 51 extends in substantially the same direction as the short side A, while the lower long hole 52 extends in the vertical direction and is slightly inclined with respect to the short side A. doing. For this reason, both the support shafts 46 and 47 for each of the end fins 41 and 42 can be rotated in the long holes 51 and 52 and can be moved in the extending direction of the long holes 51 and 52.

  Both support shafts 45 of the intermediate fin 43 protrude outward from the nearest first wall portions 26 and 27 (a direction away from the retainer 20 in the direction along the long side B). The projecting portion of each support shaft 45 abuts on the support shaft 46 of the end fin 41 from the lower side (intermediate fin 43 side) and is above the support shaft 47 of the end fin 42 (intermediate fin 43 side). A cam member 53 that comes into contact with each other is provided so as to be integrally tiltable. The cam member 53 has a connecting shaft 54 that protrudes outward from a location on the upstream side of the support shaft 45 of the intermediate fin 43. The intermediate fin 43, the support shaft 45, the cam member 53, and the connecting shaft 54 are integrally formed by injection molding.

  Further, both the support shafts 46 of the upper end fin 41 protrude outward from the nearest first wall portions 26 and 27. An arm 55 extending upstream from the support shaft 46 is formed at the protruding portion of each support shaft 46. A connecting shaft 56 protrudes outward from the upstream end portion (extending end portion) of the arm 55. The end fin 41, the support shaft 46, the arm 55, and the connecting shaft 56 are integrally formed by injection molding.

  Similarly, both support shafts 47 of the lower end fin 42 protrude outward from the nearest first wall portions 26 and 27. An arm 57 extending upstream from the support shaft 47 is formed at the protruding portion of each support shaft 47. A connecting shaft 58 protrudes outward from an upstream end portion (extending end portion) of the arm 57. The end fins 42, the support shafts 47, the arms 57, and the connecting shafts 58 are integrally formed by injection molding.

  The connecting shaft 54 and the connecting shafts 56 and 58 are connected by a connecting rod 61 extending in a direction along the short side A of the opening 24. More specifically, holes 62 are formed at three positions in the length direction of the connecting rod 61, and the connecting shafts 54, 56, and 58 are rotatably engaged with these holes 62. The arms 55 and 57, the cam member 53, the connecting shafts 54, 56, and 58, the connecting rod 61, and the like described above constitute a link mechanism that mechanically connects the end fins 41 and 42 and the intermediate fin 43.

The cam member 53 has profiles 63 and 64 at its upper edge and lower edge. The upper profile 63 satisfies the following conditions.
(I) As shown in FIGS. 6 and 7, when the intermediate fin 43 is parallel to the second wall portions 28 and 29, and the end portion on the downstream side of the end fin 41 is brought close to the second wall portion 28, The intermediate portion of the profile 63 abuts on the support shaft 46 at a location (upper end portion) that approaches the second wall portion 28 in the long hole 51.

  (Ii) As shown in FIG. 8 and FIG. 9, the intermediate fin 43 is tilted upward so as to become higher toward the downstream side, so that the downstream end of the end fin 41 approaches the second wall portion 28. When the end fin 41 is tilted, the downstream side portion of the profile 63 abuts on the support shaft 46 at a location (lower end portion) away from the second wall portion 28 in the long hole 51.

  (Iii) As shown in FIG. 10 and FIG. 11, the intermediate fin 43 is tilted downward so as to become lower toward the downstream side, and the downstream end portion of the end fin 41 moves away from the second wall portion 28. When the end fin 41 is tilted, the upstream side portion of the profile 63 abuts on the support shaft 46 at a location (upper end portion) that approaches the second wall portion 28 in the long hole 51.

On the other hand, the lower profile 64 satisfies the following conditions.
(Iv) As shown in FIGS. 6 and 7, when the intermediate fin 43 is parallel to the second wall portions 28 and 29, and the end portion on the downstream side of the end fin 42 is brought close to the second wall portion 29, The intermediate portion of the profile 64 abuts on the support shaft 47 at a location (lower end portion) that is close to the second wall portion 29 in the long hole 52.

  (V) As shown in FIG. 8 and FIG. 9, the intermediate fin 43 is tilted upward so as to become higher toward the downstream side, and the downstream end portion of the end fin 42 moves away from the second wall portion 29. When the end fin 42 is tilted, the upstream side portion of the profile 64 abuts on the support shaft 47 at a location (lower end portion) near the second wall portion 29 in the long hole 52.

  (Vi) As shown in FIGS. 10 and 11, the intermediate fin 43 is tilted downward so that the downstream fin is lower, and the downstream end of the end fin 42 approaches the second wall 29. When the end fin 42 is tilted, the downstream side portion of the profile 64 abuts on the support shaft 47 at a location (upper end portion) away from the second wall portion 29 in the long hole 52.

  Further, there is provided a restricting portion for restricting the support shaft 46 with which the cam member 53 is abutted in the upper profile 63 from moving toward the second wall portion 28 with respect to the abutting position. The restricting portion includes a downstream end contact portion 65 and a support shaft contact portion 66. The downstream end contacted portion 65 is a location where the downstream end of the end fin 41 contacts the inner wall surface of the upper second wall portion 28. The support shaft abutted portion 66 is an end portion (upper end portion) of the long hole 51 on the second wall portion 28 side, and is a place where the support shaft 46 is contacted.

  Then, the movement of the support shaft 46 is restricted by one of the downstream end contact portion 65 and the support shaft contact portion 66. In the present embodiment, the type of the restricting portion (contacted portion) that restricts the movement of the support shaft 46 is switched as follows according to the tilting direction of the end fin 41.

  (I) As shown in FIGS. 6 and 7, when both the end portion on the downstream side of the end fin 41 and the support shaft 46 are brought close to the second wall portion 28 (the end fin 41 is parallel to the second wall portion 28). ), The movement of the support shaft 46 is restricted by the support-contacted portion 66.

  (II) As shown in FIG. 8 and FIG. 9, when the end fin 41 is tilted toward the side where the downstream end of the end fin 41 approaches the second wall portion 28, the downstream end contacted portion 65 The movement of the support shaft 46 is restricted.

  (III) As shown in FIGS. 10 and 11, when the end fin 41 is tilted toward the side where the downstream end of the end fin 41 is away from the second wall portion 28, The movement of the support shaft 46 is restricted.

  Further, there is provided a restricting portion for restricting the support shaft 47 with which the cam member 53 is in contact with the lower profile 64 from moving to the second wall portion 29 side from the contact position. The restricting portion includes a downstream end contact portion 67 and a support shaft contact portion 68. The downstream end abutted portion 67 is a location where the downstream end portion of the end fin 42 abuts on the inner wall surface of the lower second wall portion 29. The support shaft contact portion 68 is an end portion (lower end portion) of the long hole 52 on the second wall portion 29 side, and is a place where the support shaft 47 is contacted.

  Then, the movement of the support shaft 47 is restricted by one of the downstream end contact portion 67 and the support shaft contact portion 68. In the present embodiment, the type of the restricting portion (contacted portion) that restricts the movement of the support shaft 47 is switched as follows according to the tilting direction of the end fins 42.

  (IV) As shown in FIGS. 6 and 7, when both the end portion on the downstream side of the end fin 42 and the support shaft 47 are brought close to the second wall portion 29 (the end fin 42 is parallel to the second wall portion 29). ), The movement of the support shaft 47 is restricted by the support shaft contact portion 68.

  (V) As shown in FIG. 8 and FIG. 9, when the end fin 42 is tilted toward the side where the end fin 42 on the downstream side is away from the second wall portion 29, The movement of the support shaft 47 is restricted.

  (VI) As shown in FIGS. 10 and 11, when the end fin 42 is tilted to the side where the downstream end of the end fin 42 approaches the second wall portion 29, the downstream end contacted portion 67 The movement of the support shaft 47 is restricted.

<Upstream fin group 70>
As shown in FIG. 2, the upstream fin group 70 is a plurality of sheets extending near the upstream side of the downstream fin group 40 in the retainer 20 and extending along the short side A of the opening 24 (substantially up and down direction). It consists of upstream fins 71. These upstream fins 71 are each formed in a flat and slender shape having a predetermined width in the direction along the ventilation path 23, and are arranged in a state of being separated from each other in the direction along the long side B (vehicle width direction). ing.

  Support shafts (not shown) are respectively provided on both end faces of each upstream fin 71 in the direction along the short side A. And each upstream fin 71 is rotatably supported by the 2nd wall part 28 and 29 in both the support shafts. Therefore, each upstream fin 71 can tilt in the direction along the long side B of the opening 24 (vehicle width direction) with these support shafts as fulcrums.

Next, the operation of the air conditioning register 15 of the present embodiment configured as described above will be described.
In this air-conditioning register 15, the opening 24 at the downstream end of the retainer 20 has a rectangular shape, and the space in which the downstream fins (intermediate fins 43, end fins 41, 42) are arranged is narrow in the arrangement direction. However, in this embodiment, the number of downstream fins is three, which is the minimum number that can be taken for wind direction adjustment. Therefore, the space (flow path) between the adjacent downstream fins (between the intermediate fins 43 and the end fins 41 and 42) is sufficiently large while ensuring the wind direction adjustment function.

  In the air conditioning register 15, each of the intermediate fins 43 and the end fins 41 and 42 can tilt with respect to the first wall portions 26 and 27 with the support shafts 45 to 47 as fulcrums. In addition to this, as shown in FIG. 5, the support shaft 46 of the end fin 41 is along a long hole 51 provided between the upstream member 21 and the downstream member 22 of each first wall portion 26, 27. It can move in the direction along the short side A. Further, the support shaft 47 of the end fin 42 is movable in the direction along the short side A along the long hole 52 provided between the upstream member 21 and the downstream member 22 of each first wall portion 26, 27. It is.

  Here, as shown in FIG. 4, a connecting shaft 54 provided on the intermediate fin 43 via the cam member 53 and the support shaft 45, and a connecting shaft provided on the end fin 41 via the arm 55 and the support shaft 46. 56 and a connecting shaft 58 provided on the end fin 42 via the arm 57 and the support shaft 47 are connected by a connecting rod 61.

  A cam member 53 that tilts integrally with the intermediate fin 43 via the support shaft 45 is in contact with the support shaft 46 of the end fin 41 from the intermediate fin 43 side (lower side). Similarly, the cam member 53 is in contact with the support shaft 47 of the end fin 42 from the intermediate fin 43 side (upper side).

  Further, the support shaft 46 with which the cam member 53 is in contact moves from the contact position toward the second wall portion 28, so that the restricting portion (the downstream end contact portion 65 and the support shaft contact portion 66). ). Similarly, the support shaft 47 with which the cam member 53 is in contact moves from the contact position to the second wall portion 29 side, so that the restriction portion (the downstream end contact portion 67 and the support shaft contact portion). 68).

  Therefore, the position of the support shafts 46 and 47 in the long holes 51 and 52 and the inclination of the end fins 41 and 42 are caused by the connection using the connection rod 61, the contact of the cam member 53, and the restriction of the restriction portion. It is determined. Unless the intermediate fin 43 is tilted, the support shafts 46 and 47 are held at the determined positions, and the end fins 41 and 42 are held at the determined inclination.

  Therefore, the air flowing through the ventilation path 23 blows out from the opening 24 after passing through the flow path between the intermediate fins 43 and the end fins 41 and the flow path between the intermediate fins 43 and the end fins 42. The direction of the air is adjusted by the intermediate fins 43 and the end fins 41 and 42 when passing through the flow path.

  6 and 7 show a state in which the intermediate fins 43 are parallel to the ventilation direction (second wall portions 28 and 29). In this state, the downstream end portion of the upper end fin 41 is brought close to the second wall portion 28, and the intermediate portion of the profile 63 of the cam member 53 is a long hole with respect to the support shaft 46 of the end fin 41. In 51, it contacts in the location which approached the 2nd wall part 28. FIG. Further, the downstream end portion of the lower end fin 42 is brought close to the second wall portion 29, and the intermediate portion of the profile 64 of the cam member 53 with respect to the support shaft 47 of the end fin 42 is a long hole 52. At the location approaching the second wall 29.

  Therefore, the end fins 41 and 42 are also in parallel with the second wall portions 28 and 29, as with the intermediate fins 43. Air flows through the flow path between the intermediate fins 43 and the end fins 41 and the flow path between the intermediate fins 43 and the end fins 42 along the downstream fins. Flow in parallel. That is, the air flows in the flow path between the adjacent downstream fins while maintaining the direction on the upstream side of the downstream fin group 40. Then, air blows out in parallel to the second wall portions 28 and 29 from the opening 24 at the downstream end of the retainer 20.

  6 and 7, when the intermediate fin 43 is tilted upward (counterclockwise in the figure) with the support shaft 45 as a fulcrum as shown in FIGS. 8 and 9, the intermediate fin 43 is It inclines so that it may become higher downstream.

  The tilt of the intermediate fin 43 is transmitted to the end fins 41 and 42 via the connecting shafts 54, 56 and 58, the connecting rod 61 and the like. Further, the contact of the cam member 53 with respect to the support shafts 46 and 47 of the end fins 41 and 42 and the restriction of the restricting portion are performed regardless of the tilting of the intermediate fin 43. The end fins 41 and 42 are tilted in the same direction as the intermediate fin 43 in conjunction with the intermediate fin 43 with the support shafts 46 and 47 whose positions are determined as described above as fulcrums.

  That is, with respect to the upper end fin 41, the downstream end portion of the end fin 41 approaches the upper second wall portion 28 and contacts the downstream end contacted portion 65 as the intermediate fin 43 tilts. . Further, the downstream side portion of the profile 63 of the cam member 53 comes into contact with the support shaft 46 from the lower side at a position away from the upper second wall portion 28 with respect to the upper long hole 51. Therefore, the support shaft 46 on the upstream side of the end fin 41 moves away from the upper second wall portion 28 downward. Therefore, the downstream end of the upper end fin 41 and the upstream support shaft 46 are greatly separated in the direction along the short side A (substantially up and down direction). As a result, the upper end fin 41 is in an inclined state in which the upstream end portion moves away from the upper second wall portion 28 and the downstream end portion approaches the second wall portion 28, that is, in the middle. Like the fins 43, the inclined state becomes higher toward the downstream side.

  At this time, even if the support shaft 46 in contact with the downstream side portion of the profile 63 of the cam member 53 attempts to move to the second wall portion 28 side above the contact position, the movement is not the end. The lower end of the fin 41 is regulated by the upper downstream end contact portion 65 with which the downstream end is in contact.

  Further, with respect to the lower end fin 42, the downstream end portion of the end fin 42 moves away from the lower second wall portion 29 as the intermediate fin 43 tilts. At this time, the upstream side portion of the profile 64 of the cam member 53 comes into contact with the support shaft 47 from the upper side at a position close to the second wall portion 29 with respect to the lower elongated hole 52. Therefore, the support shaft 47 on the upstream side of the end fin 42 approaches the lower second wall portion 29 and comes into contact with the support-contacted portion 68 of the long hole 52. Therefore, the downstream end portion of the lower end fin 42 and the upstream support shaft 47 are greatly separated in the direction along the short side A (substantially up and down direction). As a result, the lower end fin 42 is in an inclined state in which the upstream end approaches the lower second wall 29 and the downstream end moves upward from the second wall 29, that is, Like the intermediate fin 43, the inclined state becomes higher at the downstream side.

  At this time, even if the support shaft 47 in contact with the upstream side portion of the profile 64 of the cam member 53 tries to move to the second wall portion 29 side below the contact position, the movement is It is regulated by a pivot abutted portion 68 with which the pivot 47 abuts.

  Therefore, the air flowing through the ventilation path 23 is changed in direction in the process of flowing along the downstream fins in the flow path between the intermediate fin 43 and the end fins 41 and 42 tilted as described above, and opens. Blow out from 24. As described above, the end fins 41 and 42 are inclined so as to become higher toward the downstream side in the same manner as the intermediate fins 43, so that air is accurately blown out obliquely upward, which is the target direction.

  In contrast to the above, when the intermediate fin 43 is tilted downward (clockwise in the figure) with the support shaft 45 as a fulcrum as shown in FIGS. The intermediate fin 43 is inclined so as to become lower toward the downstream side.

  The tilt of the intermediate fin 43 is transmitted to the end fins 41 and 42 via the connecting shafts 54, 56, and 58, the connecting rod 61, and the like. Further, the contact of the cam member 53 with respect to the support shafts 46 and 47 of the end fins 41 and 42 and the restriction of the restricting portion are performed regardless of the tilting of the intermediate fin 43. The end fins 41 and 42 are tilted in the same direction as the intermediate fin 43 in conjunction with the intermediate fin 43 with the support shafts 46 and 47 whose positions are determined as described above as fulcrums.

  That is, for the upper end fin 41, the downstream end portion of the end fin 41 moves away from the upper second wall portion 28 as the intermediate fin 43 is tilted. At this time, the upstream side portion of the upper profile 63 of the cam member 53 comes into contact with the support shaft 46 at a position close to the upper second wall portion 28 with respect to the upper long hole 51. For this reason, the support shaft 46 on the upstream side of the end fin 41 approaches the second wall portion 28 on the upper side, and contacts the support-contacted portion 66 of the long hole 51. Therefore, the downstream end of the upper end fin 41 and the upstream support shaft 46 are greatly separated in the direction along the short side A (substantially up and down direction). As a result, the upper end fin 41 is in an inclined state in which the upstream end portion approaches the upper second wall portion 28 and the downstream end portion moves away from the second wall portion 28, that is, in the middle. Similar to the fins 43, the inclined state becomes lower toward the downstream side.

  At this time, even if the support shaft 46 in contact with the upstream side portion of the profile 63 of the cam member 53 attempts to move to the second wall portion 28 side above the contact position, the movement is supported. The shaft 46 is regulated by the abutted portion 66 to which the shaft 46 abuts.

  Further, with respect to the lower end fin 42, the downstream end of the end fin 42 approaches the lower second wall portion 29 as the intermediate fin 43 is tilted, so that the lower end fin 42 becomes the downstream end contact portion 67. Abut. Further, the downstream side portion of the profile 64 of the cam member 53 contacts the support shaft 47 from the upper side at a position away from the lower second wall portion 29 with respect to the lower elongated hole 52. Therefore, the support shaft 47 on the upstream side of the end fin 42 moves away from the second wall portion 29 on the lower side. Therefore, the downstream end portion of the lower end fin 42 and the upstream support shaft 47 are greatly separated in the direction along the short side A (substantially up and down direction). As a result, the lower end fin 42 is in an inclined state in which the upstream end portion moves away from the lower second wall portion 29 and the downstream end portion approaches the second wall portion 29, that is, As with the intermediate fin 43, the inclined state becomes lower at the downstream side.

  At this time, even if the support shaft 47 in contact with the downstream side portion of the profile 64 of the cam member 53 tries to move to the second wall portion 29 side below the contact position, the movement is The lower end of the end fin 42 is regulated by the lower end abutted portion 67 that is in contact with the lower end.

  Therefore, the air flowing through the ventilation path 23 is changed in direction in the process of flowing along the downstream fins in the flow path between the intermediate fin 43 and the end fins 41 and 42 tilted as described above, and opens. Blow out from 24. As described above, since the end fins 41 and 42 are inclined so as to become lower toward the downstream side in the same manner as the intermediate fins 43, air is accurately blown out obliquely downward, which is the target direction.

According to the embodiment described in detail above, the following effects can be obtained.
(1) The first wall portion 26 has long holes 51 and 52 that extend in the direction along the short side A of the opening 24 and allow movement of the support shafts 46 and 47 in the end fins 41 and 42 in the same direction. , 27. A cam member 53 that comes into contact with the support shafts 46 and 47 of the end fins 41 and 42 from the side of the intermediate fin 43 is provided on the support shaft 45 of the intermediate fin 43 so as to be integrally tiltable. A restricting portion (downstream end contacted portion) that restricts movement of the support shafts 46 and 47 with which the profiles 63 and 64 of the cam member 53 are in contact with the second wall portions 28 and 29 from the contact position. Portions 65 and 67 and spindle contact portions 66 and 68). As the cam member 53 tilts, the positions of the support shafts 46 and 47 in the long holes 51 and 52 are changed by changing the contact positions of the profiles 63 and 64 of the cam member 53 with respect to the support shafts 46 and 47. I am doing so. In other words, the air-conditioning register 15 is configured such that the end fins 41 and 42 have a plurality of support shafts 46 and 47 and tilt with the support shafts 46 and 47 as fulcrums.

  Therefore, compared with the background art (described in Patent Document 1), the end fins 41 and 42 are moved in the same direction as the intermediate fin 43 in conjunction with the tilting of the intermediate fin 43 while having a simple structure with fewer parts. And can be blown out accurately in the direction aimed at air, that is, good directivity can be ensured.

  Further, the support shafts 46 and 47 of the end fins 41 and 42 can be moved in the long holes 51 and 52 extending in the direction along the short side A. For this reason, by moving the support shafts 46 and 47 closer to or away from the second wall portions 28 and 29, the end fin fins 41 and 42 between the end fins 41 and 42 and the second wall portions 28 and 29. 42 can be secured, and the retainer 20 does not have to be enlarged in the direction along the short side A (substantially in the vertical direction).

  Therefore, not only can the opening 24 of the bezel 22A be horizontally long to enhance the design of the air conditioning register 15, but also the space of the air conditioning register 15 in the instrument panel 11 can be reduced, and the other components in the instrument panel 11 can be reduced. Equipment installation space can be secured.

  (2) The downstream fin group 40 is composed of only three downstream fins such as a pair of upper and lower end fins 41 and 42 and one intermediate fin 43 disposed therebetween. This number (three) is the minimum number required for wind direction adjustment.

Therefore, it is possible to efficiently increase the interval between adjacent downstream fins (between the intermediate fin 43 and the end fins 41 and 42) while ensuring the wind direction adjusting function.
(3) When the intermediate fin 43 is parallel to the second wall portions 28 and 29, the downstream end portion is in relation to the support shafts 46 and 47 of the end fins 41 and 42 that are close to the second wall portions 28 and 29. The profiles 63 and 64 of the cam member 53 are brought into contact with the long holes 51 and 52 at locations close to the second wall portions 28 and 29.

  Therefore, in addition to the intermediate fin 43, the upper and lower end fins 41, 42 are parallel to or close to the second wall portions 28, 29, and air is passed from the opening 24 at the downstream end of the retainer 20 to the second wall portions 28, 29. 29 can be blown out in parallel.

  (4) The support shafts 46 and 47 of the end fins 41 and 42 are provided at the upstream end of the end fins 41 and 42. When the end fins 41, 42 are tilted toward the side where the downstream end portions of the end fins 41, 42 approach the second wall portions 28, 29, the cam member 53 is inserted into the long holes (movement allowing portions) 51, 52. Is brought into contact with the support shafts 46 and 47 at positions away from the second wall portions 28 and 29. Further, when the end fins 41 and 42 are tilted toward the side where the downstream end portions of the end fins 41 and 42 move away from the second wall portions 28 and 29, the cam member 53 is inserted into the long hole (movement allowing portion) 51. , 52 are brought into contact with the support shafts 46, 47 at locations close to the second wall portions 28, 29.

Therefore, the end fins 41 and 42 can be inclined so that the downstream end and the upstream support shafts 46 and 47 are greatly separated in the direction along the short side A.
(5) Downstream end abutted portions 65 and 67, which are provided on the inner wall surface of the retainer 20 (second wall portions 28 and 29) and contact the downstream end portions of the end fins 41 and 42, and The ends 51 and 52 are provided at the ends of the second wall portions 28 and 29 and are supported by the shaft-contacted portions 66 and 68 to which the shafts 46 and 47 of the end fins 41 and 42 are abutted. A restricting portion for each of the fins 41 and 42 is formed. When the end fins 41, 42 are tilted toward the side where the downstream end portions of the end fins 41, 42 are away from the second wall portions 28, 29, the support shaft 46 is supported by the support shaft abutted portions 66, 68. , 47 is restricted. When the end fins 41 and 42 are tilted toward the side where the downstream end portions of the end fins 41 and 42 approach the second wall portions 28 and 29, the support shaft 46 is supported by the downstream end contact portions 65 and 67. , 47 is restricted.

  Therefore, when the end fins 41 and 42 tilt toward the side where the downstream end portion moves away from the second wall portions 28 and 29, and when the end fins 41 and 42 tilt toward the approaching side, that is, the end fin 41, In accordance with the tilting direction of 42, the abutted portions for restricting the movement of the support shafts 46 and 47 can be appropriately switched for the downstream end contacted portions 65 and 67 and the support shaft contacted portions 66 and 68. .

  (6) The intermediate fin 43, the support shaft 45, the cam member 53, and the connecting shaft 54 are integrally formed by injection molding. Further, the end fin 41, the support shaft 46, the arm 55 and the connecting shaft 56 are integrally formed by injection molding. Further, the end fin 42, the support shaft 47, the arm 57, and the connecting shaft 58 are integrally formed by injection molding.

Thus, since the components of the tilt transmission mechanism 50 are integrally formed by injection molding, it is possible to minimize the cost increase associated with adding a new configuration.
Note that the present invention can be embodied in another embodiment described below.

  The structure of the restricting portion that restricts the movement of the support shafts 46 and 47 with which the cam member 53 is in contact to the second wall portions 28 and 29 from the contact position is different from that of the above embodiment. You may change to

  FIG. 12 shows an example (modified example). In this modification, as shown in FIG. 12, the cam member 53 is provided with a pair of upper and lower guide holes 75 through which the support shafts 46 and 47 of the upper and lower end fins 41 and 42 are inserted. The cam member 53 comes into contact with the support shafts 46 and 47 from the side of the intermediate fin 43 on the inner wall surface 75A farther from the nearest second wall portions 28 and 29 in the guide holes 75.
