Description

  The present invention relates to a thin air-conditioning register having a rectangular opening at the downstream end as a blowout port for air sent from an air conditioner and adjusting the direction of air blown from the opening.

  In a vehicle such as an automobile, a display device may be installed in a center cluster of an instrument panel for operation of equipment such as a navigation system and display of equipment status. In this case, as indicated by a solid line in FIG. 11, the display unit 91 (screen portion) of the display device is arranged above the center cluster 92 from the viewpoint of reducing the driver's viewpoint movement. In addition to the display unit 91, it is necessary to provide an air conditioning register 93 that constitutes the air outlet of the air conditioner on the upper portion of the center cluster 92. Conventionally, the air conditioning register 93 is provided on both the display units 91. It was placed on the side (both sides in the vehicle width direction).

  By the way, the display unit 91 is steadily increasing in size as shown by a two-dot chain line in FIG. In this case, the positions of the air conditioning registers 93 on both sides of the display unit 91 are also changed outward in the vehicle width direction.

  However, since the right air-conditioning register 93 approaches the steering wheel (steering wheel) 94 as the position is changed, the following problem newly arises. One of them is that the air blown from the right air-conditioning register 93 directly hits the driver's arm holding the handle 94, and the driver may feel annoyed. Further, when the air blown out from the right air-conditioning register 93 is obstructed by the driver's arm, there is a problem that the air hardly circulates in the passenger compartment.

  For this, it is conceivable that the air-conditioning register 93 is arranged directly above the both sides of the display unit 91. However, if the conventional air-conditioning register 93 is arranged as it is directly above the display unit 91, the height of the instrument panel 95 including the center cluster 92 increases accordingly. As a result, it is difficult to obtain a feeling of opening, and conversely, there is a risk of causing the passenger to feel a feeling of pressure or a feeling of obstruction.

  Therefore, an attempt has been made to keep the height of the instrument panel 95 low by using an air conditioning register 93 disposed directly above the display unit 91 that is thin in the vertical direction (thin air conditioning register). Yes.

  For example, Patent Document 1 describes an air conditioning thin register 97 including a retainer 96, a fin group, and a fin angle setting mechanism 106, as shown in FIG. The retainer 96 is a cylindrical body having a ventilation path 98 in the internal space and a blowout port 99 having a horizontally long rectangular shape at the downstream end. In the retainer 96, among the four wall portions surrounding the ventilation path 98, the one corresponding to the short side A of the outlet 99 (left and right side walls) is the first wall portion 101, and the one corresponding to the long side B (upper wall) , Lower wall) is the second wall portion 102.

  The fin group is composed of a plurality of fins 103, 104, 105 extending in the direction along the long side B (vehicle width direction) in the retainer 96, and these fins 103 to 105 are in the direction along the short side A (substantially up and down direction). ) Are separated from each other. Each fin 103-105 is supported by the 1st wall part 101 so that inclination is possible at the both ends about the direction along those long sides B, respectively.

  Of the fin group, the fins 103 and 105 located at both ends in the arrangement direction are disposed close to the second wall portion 102. Furthermore, the fins 103 and 105 are divided into two members (upstream divided pieces 103a and 105a and downstream divided pieces 103b and 105b) in a direction along the ventilation path 98.

  The fin angle setting mechanism 106 sets angles (inclinations) of the upstream divided pieces 103a and 105a and the downstream divided pieces 103b and 105b of the fins 103 and 105, respectively. When the fin 104 is tilted upward or downward, the fin angle setting mechanism 106 is a downstream side divided piece 103b of the fin 103 (105) located on the same side as the tilted direction of the fins 103 and 105. (105b) is held parallel to the second wall 102. In addition, the fin angle setting mechanism 106 tilts the upstream divided piece 103a (105a) in the same direction in synchronization with the tilt of the fin 104. In addition, the fin angle setting mechanism 106 uses the downstream divided piece 105b (103b) of the fin 105 (103) positioned on the opposite side of the tilted direction of the fins 103 and 105 as the tilt of the fin 104. Tilt in the same direction synchronously. In addition to this, the fin angle setting mechanism 106 holds the upstream divided piece 105 a (103 a) in a state parallel to the second wall portion 102.

For example, as shown in FIG. 13, when the intermediate fin 104 is tilted so as to become higher toward the downstream side, the fin angle setting mechanism 106 causes the downstream divided piece 103 b to be parallel to the second wall portion 102 for the fin 103. In this state, the upstream divided piece 103 a is tilted in the same direction as the fins 104. Further, the fin angle setting mechanism 106 tilts the downstream divided piece 105 b in the same direction as the fin 104 for the fin 105, and holds the upstream divided piece 105 a in a state parallel to the second wall portion 102.
Japanese Patent No. 3572480

  According to the air-conditioning thin register 97 described in the above-mentioned Patent Document 1, the conventional air-conditioning register 93 (see FIG. 11) simply becomes thin, that is, when the fins 104 are greatly inclined, they are adjacent to each other. The problem that the interval between the fins 103 to 105 becomes narrow and it is difficult to secure the air flow path can be solved. However, as long as the thin air conditioning register 97 described in Patent Document 1 adopts the above-described structure as the fin angle setting mechanism 106, the fin 103 (105) positioned on the same side as the direction in which the intermediate fin 104 is tilted. The upstream divided pieces 103a (105a) are tilted in the same direction in synchronization with the tilt of the fins 104. Along with this tilting, as shown by a two-dot chain line in FIG. 13, a space 107 whose vertical width (height) increases between the second wall portion 102 and the upstream divided piece 103a (105a) on the upstream side. The space 107 is formed as an air accumulation part. Then, air enters the space 107 and becomes a vortex, which may generate noise. Further, there is a concern that the pressure loss increases as air flows into the space 107.

  The present invention has been made in view of such circumstances, and its purpose is to generate a large flow path between adjacent fins, generate noise between the fins and the second wall portion, and pressure loss. An object of the present invention is to provide a thin air-conditioning register that can eliminate the problem of increasing the air flow.

  In order to achieve the above-described object, the invention according to claim 1 is a four-wall portion that is formed of a cylindrical body that has an internal space as a ventilation path and has a rectangular opening at a downstream end, and surrounds the ventilation path. A retainer having a first wall portion corresponding to the short side of the opening and a second wall portion corresponding to the long side, and three or more extending in the direction along the long side in the retainer A fin group composed of plate-like fins, these fins being arranged in a state of being separated from each other in the direction along the short side, and each fin supported by the first wall portion so as to be tiltable by a support shaft; A thin air-conditioning register comprising fins located at both ends in the arrangement direction of the fin group as end fins in the vicinity of the second wall portion, and the end fins at the support shaft A main body supported by the first wall, and a front And a bendable portion that is arranged on the upstream side of the main body portion and can be bent with respect to the main body portion, and further, in the vicinity of the second wall portion, upstream of the bent portion as the main body portion tilts. The gist is that a movement allowing portion that allows the end to move in the ventilation direction or in the opposite direction in a state of approaching the second wall portion is provided.

  According to said structure, the end fin in a fin group is arrange | positioned in the vicinity of a 2nd wall part, and the clearance gap between those end fins and a 2nd wall part becomes narrow. Accordingly, the distance between the end fins at both ends in the arrangement direction is increased, and the distance between adjacent fins is increased accordingly. Therefore, although the air conditioning thin register is thin in the fin arrangement direction, a large flow path can be secured between adjacent fins even when each fin is inclined with respect to the ventilation direction.

  When the air flowing in the vicinity of the second wall portion in the air passage of the retainer passes through the end fins, the direction of the air is changed by flowing along the upstream bent portion and the downstream main body portion. Then, the air whose direction is changed by the main body blows out in the same direction from the opening at the downstream end of the retainer.

  By the way, in the air conditioning thin register, the main body portion of the end fin can be tilted with the support shaft as a fulcrum. Further, the bent portion of the end fin can be bent with respect to the main body portion tilting as described above. The upstream end of the bent portion is movable in the ventilation direction or the opposite direction at the movement allowing portion. By this movement, the position of the upstream end of the bent portion in the movement allowing portion changes, so that the tilting of the main body portion and the bending portion are permitted. And the bending degree of an end fin changes with tilting of the said main-body part, and rotation of a bending part, and the direction of the air which blows off from the opening of a retainer is changed.

  Here, the movement of the upstream end of the bent portion is performed with the upstream end approaching the second wall portion regardless of the position of the upstream end of the movement allowing portion. Therefore, a space is not always easily generated between the upstream end of the bent portion and the second wall portion. Therefore, generation of noise and increase in pressure loss, which are inconveniences caused by such a space, are suppressed.

The gist of the invention of claim 2 is that, in the invention of claim 1, the bent portion is connected to the upstream end of the main body portion so as to be rotatable by a shaft.
According to said structure, a bending part can be bent with respect to the upstream end of a main-body part by rotating centering on an axis | shaft. Therefore, in each end fin, the position of the upstream end of the bent portion in the movement-permitting portion changes, so that tilting of the main body portion with the support shaft as a fulcrum and rotation of the bent portion with the shaft as a fulcrum are permitted. The And the bending degree of an end fin changes with tilting of the said main-body part and rotation of a bending part.

The gist of the invention of claim 3 is that, in the invention of claim 1, the bent portion is formed integrally with the upstream end of the main body portion by a soft material.
According to said structure, the bending part integrally formed in the upstream end of the main-body part with the soft material can be bent with respect to the upstream end of the main-body part by elastically deforming. Therefore, in each end fin, the position of the upstream end of the bent portion in the movement allowing portion changes, so that tilting of the main body with the support shaft as a fulcrum and elastic deformation of the bent portion are allowed. And the bending degree of an end fin changes with the tilting of the said main-body part and the elastic deformation of a bending part. Further, in this case, since the bent portion is elastically deformed so as to swell in the tilting direction of the main body portion, the air flowing direction is smoothly changed by the elastically deformed bent portion.

  According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, the fin group includes the pair of end fins and one sheet disposed between the end fins. The gist is that it consists of intermediate fins.

  The opening at the downstream end of the retainer has a rectangular shape, and the space in which the fins are arranged is narrow in the arrangement direction. However, according to said structure, the space | interval (flow path) between adjacent fins can be enlarged efficiently, ensuring a wind direction adjustment function by having made the number of fins into three pieces.

  According to a fifth aspect of the present invention, in the invention according to any one of the first to fourth aspects of the present invention, the movement-permitting portion is configured such that the ventilation direction is in the boundary portion between the first wall portion and the second wall portion. And a groove portion into which a pin protruding from the upstream end of the side surface of the bent portion is engaged.

  According to said structure, the pin which protruded from the side surface of the bending part and was engage | inserted in the groove part of the movement permissible part can move to the ventilation direction which is the extension direction of the groove part, or its reverse direction. And by changing the position of the pin in the groove, tilting of the main body and bending of the bent portion are allowed.

  Here, since the pin is provided at the upstream end of the bent portion and the movement allowing portion is provided at the boundary portion between the first wall portion and the second wall portion, the pin moves in the groove portion. Thus, regardless of the position of the pin, the upstream end of the bent portion moves in the ventilation direction or in the opposite direction while approaching the second wall portion. Therefore, a space is not always easily generated between the upstream end of the bent portion and the second wall portion.

  According to the thin air-conditioning register of the present invention, since the end fins are arranged in the vicinity of the second wall portion, a large flow path can be secured between adjacent fins while being thin. In addition, since the end fin is provided with a main body portion and a bent portion, and the movement allowing portion is provided on the second wall portion, a space is provided between the end fin and the second wall portion regardless of the inclination of the end fin. The generation of noise and the increase in pressure loss, which are problems caused by the generation of the space, can be suppressed.

  Hereinafter, an embodiment embodying the present invention 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.

  As shown in FIG. 1, an instrument panel 11 is provided in front of a driver seat and a passenger seat of a vehicle, and a center cluster 12 is provided in the center in the vehicle width direction. A display unit 13 of a display device in the navigation system is attached to 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 thin air-conditioning registers 15 and 15 are assembled in the vehicle width direction above the center cluster 12 and directly above the display unit 13. These thin air conditioning registers 15 and 15 are for adjusting the direction (air direction) of the air sent from the air conditioner and blown into the passenger compartment, or for blocking the blowing of the air.

  The reason why the thin air-conditioning registers 15 and 15 are arranged at the above-mentioned locations is that if they are arranged on both sides of the display unit 13 (both sides in the vehicle width direction), the following problems occur. (I) The air blown from the right air-conditioning thin 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 thin register 15 is less likely to circulate in the passenger compartment.

  Here, by incorporating the air conditioning thin registers 15 and 15 directly above the display unit 13, as shown by a two-dot chain line in FIG. 1, when the height of the instrument panel 11 is increased, it is difficult to obtain a feeling of opening. Conversely, there is a risk of causing the passenger to feel a feeling of pressure or a blockage. Therefore, by using a low-profile air conditioning register 15 (thin type), the height of the instrument panel 11 is kept low as shown by the solid line in FIG. We try to solve the above problems such as making you feel.

  The air conditioning thin registers 15 and 15 have substantially the same configuration. As shown in FIG. 3, each air conditioning thin register 15 includes a retainer 20, a downstream fin group 40, an upstream fin group 60, a shut damper 80, and the like. Next, the basic configuration of each unit will be described.

<Retainer 20>
The retainer 20 is for connecting the ventilation duct 21 of the air conditioner and the opening 12 a provided in the center cluster 12, and includes a main body 22 and a cover 23. The main body portion 22 is formed of a substantially rectangular cylindrical body having both ends opened, and the internal space is a ventilation path 24. The upstream opening 22 a in the main body 22 constitutes an air inlet from the ventilation duct 21. The opening 22 a has the same shape as the cross section orthogonal to the ventilation path 24. Further, the downstream opening 22 b in the main body 22 has a shape that is slightly smaller in the height direction than the cross section orthogonal to the ventilation path 24.

  The cover 23 constitutes the design surface of the retainer 20, and has an opening 23 a that is smaller than the opening 22 b of the main body 22. The opening 23a constitutes a substantial outlet of the air conditioning thin register 15. In the present embodiment, the height H of the opening 23a is set to 30 mm, and the width W is set to 120 mm (see FIG. 2). Here, the height H is a height in a cross section orthogonal to the ventilation path 24.

  The cover 23 is provided with a locking portion 25 that protrudes upstream (vehicle front side). The cover 23 is provided with an attachment portion (not shown), and the cover 23 is attached to the main body portion 22 from the downstream side in this attachment portion.

  As shown in at least one of FIGS. 2 and 3, the ventilation path 24 is surrounded by the four walls of the retainer 20. In order to distinguish these four wall portions, those corresponding to the short side A of the opening 23a in FIG. 2 are referred to as first wall portions 26, 27, and those corresponding to the long side B are referred to as second wall portions 28, 29. In the present embodiment in which the cross section orthogonal to the ventilation path 24 forms a horizontally long rectangular shape, the wall portions facing each other in the vehicle width direction become the first wall portions 26 and 27, and the wall portions facing each other in the vertical direction are the second walls. Parts 28 and 29.

  As shown in at least one of FIGS. 3 and 5, at the downstream edge 30 of the first wall portions 26 and 27, the portion corresponding to the opening 22 a is further away from the driver seat and the passenger seat toward the upper side. Inclined. In each of the first walls 26 and 27, the downstream end edge 30 inclined as described above is provided with three bearing recesses 31 at regular intervals along the inclination direction.

  The upper second wall portion 28 is provided with a plurality of bearing portions 32 at equal intervals in the direction along the long side B (vehicle width direction). Correspondingly, the bearing portions 33 are also provided at equal intervals in the direction along the long side B on the lower second wall portion 29.

<Downstream fin group 40>
The downstream fin group 40 includes three downstream fins extending in the direction along the long side B in the vicinity of the opening 23 a in the retainer 20. 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 elongated shape having a predetermined width in the direction along the ventilation path 24 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, those located at both ends in the arrangement direction are referred to as end fins 41 and 42, and those located in the center are referred to as intermediate fins 43. The end fins 41 and 42 are disposed in the vicinity of the corresponding second wall portions 28 and 29.

  As shown in at least one of FIGS. 4 to 6, each of the end fins 41, 42 and the intermediate fin 43 is both side surfaces in the direction along the long side B thereof, and is located at the downstream end of the side surface. Each of the support shafts 45 is provided. These support shafts 45 are rotatably engaged with the bearing recess 31 described above. Each support shaft 45 is locked by the locking portion 25 of the cover 23 so that it cannot be detached from the bearing recess 31. By the above engagement, each of the end fins 41 and 42 and the intermediate fin 43 can tilt in the direction along the short side A (substantially up and down direction) with the support shaft 45 as a fulcrum.

  For each of the end fins 41 and 42 and the intermediate fin 43, at least one support shaft 45 projects outward from the corresponding first wall portion (the left first wall portion 26 in the present embodiment). An arm 46 is integrally formed at each end of the projecting support shaft 45. Each arm 46 extends straight from the support shaft 45 to the upstream side, and has a connecting projection 47 at its extended end.

  Each arm 46 is connected by an elongated connecting rod 48 in a substantially vertical direction. More specifically, holes 49 are formed in the connecting rod 48 at the same intervals as the arrangement intervals of the end fins 41, 42 and the intermediate fins 43, and the connecting protrusions 47 of the arms 46 are rotated in these holes 49. It is movably engaged. A link mechanism 50 that mechanically connects the end fins 41 and 42 and the intermediate fin 43 is constituted by the arm 46, the connecting protrusion 47, the connecting rod 48, and the like.

<Upstream fin group 60>
As shown in at least one of FIGS. 2 and 3, the upstream fin group 60 is in the vicinity of the upstream side of the downstream fin group 40 in the retainer 20 and along the short side A of the opening 23a (substantially up and down direction). ) Extending a plurality of upstream fins 61. These upstream fins 61 are arranged in a state of being spaced apart in parallel with each other in the direction along the long side B of the opening 23a (vehicle width direction). Each upstream fin 61 has a thin plate shape of a substantially parallelogram that inclines so as to move away from the driver seat and the passenger seat toward the upper side.

  Support shafts 62 and 63 are provided in an inclined state on both end faces in the direction along the short side A (substantially vertical direction) of each upstream fin 61. The upper support shaft 62 is rotatably engaged with the bearing portion 32 of the second wall portion 28, and the lower support shaft 63 is rotated with the bearing portion 33 of the second wall portion 29. Engaged as possible. Therefore, each upstream fin 61 can tilt in the direction (vehicle width direction) along the long side B of the opening 23a with these support shafts 62 and 63 as fulcrums.

  For each of the upstream fins 61, one (here, the upper) support shaft 62 protrudes outward (upper) from the corresponding upper second wall portion 28. An arm 64 is formed at each end of the projecting support shaft 62. Each arm 64 extends to the downstream side (rear side of the vehicle) with the support shaft 62 as a starting point, and has a connecting projection 65 at its extended end.

  Each arm 64 is connected by an elongated connecting rod 66 in the vehicle width direction. More specifically, holes 67 are formed in the connecting rod 66 at the same intervals as the upstream fins 61, and the connecting protrusions 65 of the arms 64 are rotatably engaged with these holes 67. Has been. These arms 64, connecting protrusions 65, connecting rods 66, and the like constitute a link mechanism 68 that mechanically connects the upstream fins 61.

  In order to be able to manually adjust the inclinations of the intermediate fin 43 and the specific upstream fin 61, for example, the central upstream fin 61 with respect to the arrangement direction, an operation knob 71 is provided on the intermediate fin 43 in the vehicle width. It is externally fitted so that it can slide in the direction. A rack gear 72 is formed on the upstream surface of the operation knob 71. Correspondingly, a pinion gear 73 is formed on the specific upstream fin 61. The rack gear 72 is meshed with the pinion gear 73.

<Shut damper 80>
The shut damper 80 is for opening and closing the ventilation path 24, and is disposed on the upstream side of the upstream fin group 60 in the retainer 20. The shut damper 80 includes a damper plate 81 having a horizontally long rectangular plate shape. A seal member 82 is attached to the outer edge of the damper plate 81 over its entire circumference.

  The damper plate 81 is supported on the first wall portions 26 and 27 by the support shaft 83. The damper plate 81 is inclined in parallel with the second wall portions 28 and 29 so that the seal member 82 is largely separated from the second wall portions 28 and 29 (see the solid line in FIG. 3). It can be rotated between positions (refer to the two-dot chain line in FIG. 3) in contact with the two wall portions 28 and 29.

Although not shown, the air conditioning thin register 15 is provided with a damper operation unit that is operated when the shut damper 80 is rotated.
In the air conditioning thin register 15 having the basic structure described above, the shut damper 80 is rotated about the support shaft 83 as a fulcrum as shown in FIG. When the shut damper 80 is made parallel to the ventilation direction (second wall portions 28 and 29) by this rotation, the ventilation path 24 is fully opened, and air circulation is allowed. On the other hand, when the shut damper 80 is inclined and the seal member 82 comes into contact with the second wall portions 28 and 29, the ventilation path 24 is closed and the air flow is blocked.

  When the operation knob 71 is operated in the vehicle width direction while the shut damper 80 is parallel to the ventilation direction (second walls 28 and 29), the meshing position of the rack gear 72 and the pinion gear 73 changes, and the upstream side Among the fin group 60, the specific upstream fin 61 provided with the pinion gear 73 tilts in the same direction with the support shafts 62 and 63 as fulcrums. The movement of the upstream fin 61 is transmitted to all the other upstream fins 61 through the arm 64, the connecting protrusion 65, and the connecting rod 66, which are the constituent members of the link mechanism 68. By this transmission, all the upstream fins 61 tilt in synchronization. When the air passes through the upstream fin group 60, the air flows along the upstream fin 61 tilted as described above, and the direction is changed.

  In addition, when the operation knob 71 is operated in a substantially vertical direction in a state where the shut damper 80 is parallel to the ventilation direction (second wall portions 28, 29), the intermediate fin 43 is the same with the support shaft 45 as a fulcrum. Tilt in the direction. The movement of the intermediate fin 43 is transmitted to the end fins 41 and 42 via the arm 46, the connecting projection 47 and the connecting rod 48 which are constituent members of the link mechanism 50. By this transmission, the intermediate fin 43 and the end fins 41 and 42 are tilted synchronously. When the air passes through the downstream fin group 40, the air flows along the intermediate fins 43 and the end fins 41 and 42 tilted as described above, and the direction is changed.

Next, the characteristic part of this embodiment is demonstrated.
(A) The end fins 41 and 42 in the downstream fin group 40 are arranged in the vicinity of the second wall portions 28 and 29 and on the outer side (upper or lower) of the opening 23a. More specifically, as shown in at least one of FIGS. 3 and 5, the point that the three bearing recesses 31 are provided in the downstream end edge 30 of each first wall portion 26, 27 has been described above. Of the three bearing recesses 31, the uppermost one is provided at a location slightly higher than the upper edge of the opening 23a. The lowermost bearing recess 31 is provided at a position slightly lower than the lower edge of the opening 23a. And the end fin 41 is supported by the 1st wall parts 26 and 27 in the location a little higher than the opening 23a by engaging the spindle 45 with the bearing recessed part 31 of the uppermost step. In addition, the end fin 42 is supported by the first wall portions 26 and 27 at a position slightly lower than the opening 23a by engaging the support shaft 45 with the lowermost bearing recess 31.

  With this configuration, the gap between the end fin 41 and the second wall portion 28 is narrowed, and the gap between the end fin 42 and the second wall portion 29 is narrowed. Accordingly, the distance between the end fins 41 and 42 at both ends in the arrangement direction is increased. Accordingly, the interval between the adjacent downstream fins, that is, the interval between the end fin 41 and the intermediate fin 43 and the interval between the end fin 42 and the intermediate fin 43 are both increased.

  (B) As shown in at least one of FIGS. 3 and 6, each end fin 41, 42 has a configuration different from that of the intermediate fin 43. Specifically, the intermediate fin 43 is configured by a single member. On the other hand, the upper end fin 41 is composed of two members, a main body 51 and a bent portion 52. The lower end fin 42 is constituted by two members, a main body portion 53 and a bent portion 54.

  The main body portions 51 and 53 constitute downstream portions of the end fins 41 and 42 in the ventilation direction, and have the above-described support shaft 45. In other words, the support shaft 45 is provided on both side surfaces of the main body portions 51 and 53 in the direction along the long side B (left and right direction) at the downstream end of the side surface. Accordingly, the arm 46 and the connecting protrusion 47 described above are provided on the main body portions 51 and 53 through the support shaft 45. The main body portions 51 and 53 can tilt between the tilt position shown in FIG. 7 and the tilt position shown in FIG. 8 with the support shaft 45 as a fulcrum.

  Further, as shown in at least one of FIGS. 3 and 6, the bent portions 52 and 54 constitute upstream portions of the end fins 41 and 42 in the ventilation direction. The bent portions 52 and 54 are rotatably connected to the upstream end portions of the main body portions 51 and 53 by shafts 55 at the downstream end portions thereof. With this configuration, the bent portions 52 and 54 can be bent with respect to the upstream ends of the main body portions 51 and 53 by rotating around the shaft 55.

Further, each of the bent portions 52 and 54 is a side surface in a direction along the long side B (left and right direction), and a pin 56 projects from the upstream end of the side surface.
(C) At each upper end portion of the first wall portions 26 and 27, there is a movement allowing portion 34 that allows the upstream end of the bent portion 52 to move in the ventilation direction or the opposite direction as the main body portion 51 tilts. Each is provided. More specifically, rail portions 35 extending along the ventilation direction are provided at the upper ends of the first wall portions 26 and 27 and in the vicinity of the lower portion of the upper second wall portion 28, respectively. A space sandwiched between the rail portion 35 and the second wall portion 28 constitutes a groove portion 38 of the movement allowing portion 34. A corresponding pin 56 of the bent portion 52 is engaged with the groove portion 38 of each movement allowance portion 34. With this configuration, each pin 56 can move in the ventilation direction or the opposite direction along the groove 38 engaged.

  In the upper end fin 41, the position of the pin 56 in the movement allowance portion 34 is changed, so that the body portion 51 can be tilted with the support shaft 45 as a fulcrum and the bending portion 52 can be rotated with the shaft 55 as a fulcrum. Is done. Then, the degree of bending of the end fin 41 is changed by the tilting of the main body 51 and the rotation of the bending portion 52.

When the pin 56 is moved, the upstream end of the bent portion 52 is displaced in the same direction as the pin 56 with the upstream end of the bent portion 52 approaching the second wall portion 28 regardless of the position of the pin 56.
Similarly, at each lower end portion of the first wall portions 26 and 27, there is a movement allowance portion 36 that allows the upstream end of the bent portion 54 to move in the ventilation direction or the opposite direction as the main body portion 53 tilts. Each is provided. More specifically, rail portions 37 extending in parallel with the ventilation direction are provided at the lower ends of the first wall portions 26 and 27 and in the vicinity of the upper portion of the lower second wall portion 29, respectively. A space sandwiched between the rail portion 37 and the second wall portion 29 forms a groove portion 38 of the movement allowing portion 36. A corresponding pin 56 of the bent portion 54 is engaged with the groove portion 38 of each movement allowance portion 36. With this configuration, each pin 56 can move in the ventilation direction or the opposite direction along the groove 38 engaged.

  In the lower end fin 42, the position of the pin 56 in the movement allowing portion 36 changes, whereby the main body 53 is tilted with the support shaft 45 as a fulcrum and the bent portion 54 is rotated with the shaft 55 as a fulcrum. Permissible. The degree of bending of the end fins 42 is changed by the tilting of the main body 53 and the rotation of the bending portion 54.

When the pin 56 is moved, the upstream end of the bent portion 54 is displaced in the same direction as the pin 56 with the upstream end of the bent portion 54 approaching the second wall portion 29 regardless of the position of the pin 56.
Next, the operation of the air conditioning thin register 15 of the present embodiment having the above-described characteristic portions (a) to (c) will be described.

  3 and 4 show a state (neutral state) in which the shut damper 80 is fully opened and the intermediate fin 43 is made horizontal (air flow direction, parallel to the second walls 28 and 29) by the operation of the operation knob 71. ). In this neutral state, the air flowing through the intermediate portion in the height direction in the ventilation path 24 passes through the shut damper 80 and the upstream fin group 60, then flows along the intermediate fin 43, and blows straight out from the opening 23a.

  Since the main body 51 of the upper end fin 41 is connected in parallel to the intermediate fin 43 by the link mechanism 50, the main body 51 is also parallel to the ventilation direction (second wall portions 28, 29). ing. The pin 56 in the groove portion 38 is located in the middle of the movable range, and the bent portion 52 is inclined so as to become lower toward the downstream side. The end fins 41 are bent slightly downward. Therefore, the air flowing in the upper part of the ventilation path 24 passes through the shut damper 80 and the upstream fin group 60 and then is guided obliquely downward by the bent portion 52 and then flows along the main body portion 51 and straightly from the opening 23a. To blow out.

  Since the main body portion 53 of the lower end fin 42 is connected in parallel to the intermediate fin 43 by the link mechanism 50, the main body portion 53 is also parallel to the ventilation direction (second wall portions 28, 29). It has become. The pin 56 in the groove portion 38 is located in the middle of the movable range, and the bent portion 54 is inclined so as to become higher toward the downstream side. The end fins 42 are bent slightly upward. Therefore, after passing through the shut damper 80 and the upstream fin group 60, the air flowing in the lower part of the ventilation path 24 is guided obliquely upward by the bent portion 54, then flows along the main body portion 53, and straight from the opening 23a. To blow out.

  FIG. 7 shows a state in which the operation knob 71 is operated upward from the neutral state of FIG. 3 and the intermediate fin 43 is rotated counterclockwise in the drawing with the support shaft 45 as a fulcrum. In this state, the intermediate fin 43 is inclined so as to be higher toward the downstream side. Therefore, after flowing through the shut damper 80 and the upstream fin group 60, the air flowing through the intermediate portion in the height direction in the ventilation path 24 flows along the intermediate fin 43 and blows off obliquely upward from the opening 23a.

  The main body 51 of the end fin 41 connected to the intermediate fin 43 by the link mechanism 50 is also inclined so as to become higher toward the downstream side. The pin 56 in the groove portion 38 is located at the downstream end of the movable range, and the bent portion 52 is inclined so as to become lower toward the downstream side. The end fins 41 are greatly bent downward. Therefore, the air flowing in the upper part of the ventilation path 24 passes through the shut damper 80 and the upstream fin group 60, and is then guided obliquely downward by the bent portion 52, and then flows along the main body 51 and obliquely from the opening 23a. Blow up.

  The main body portion 53 of the end fin 42 connected to the intermediate fin 43 by the link mechanism 50 is also inclined so as to become higher toward the downstream side. The pin 56 in the groove portion 38 is positioned at the upstream end of the movable range, and the bent portion 54 is inclined so as to become higher toward the downstream side. The bent portion 54 hardly bends with respect to the main body portion 53, and the end fins 42 are substantially flat. Therefore, the air flowing in the lower part of the ventilation path 24 passes through the shut damper 80 and the upstream fin group 60 and then is guided obliquely upward by the bent portion 54, then flows along the main body portion 53, and obliquely passes through the opening 23 a. Blow up.

  FIG. 8 shows a state in which the operation knob 71 is operated downward from the neutral state of FIG. 3 and the intermediate fin 43 is rotated in the clockwise direction in the drawing with the support shaft 45 as a fulcrum. In this state, the intermediate fin 43 is inclined so as to become lower toward the downstream side. Therefore, after flowing through the shut damper 80 and the upstream fin group 60, the air flowing through the intermediate portion in the height direction in the ventilation path 24 flows along the intermediate fin 43 and blows off obliquely downward from the opening 23a.

  The main body 51 of the end fin 41 connected to the intermediate fin 43 by the link mechanism 50 is also inclined so as to become lower toward the downstream side. The pin 56 in the groove portion 38 is located at the upstream end of the movable range, and the bent portion 52 is inclined so as to become lower toward the downstream side. The bent portion 52 is hardly bent with respect to the main body portion 51, and the end fin 41 is in a substantially flat state. Therefore, the air flowing in the upper part of the ventilation path 24 passes through the shut damper 80 and the upstream fin group 60, and is then guided obliquely downward by the bent portion 52, and then flows along the main body 51 and obliquely from the opening 23a. Blow down.

  The main body 53 of the end fin 42 connected to the intermediate fin 43 by the link mechanism 50 is also inclined so as to become lower toward the downstream side. The pin 56 in the groove portion 38 is located at the downstream end of the movable range, and the bent portion 54 is greatly inclined so as to become higher toward the downstream side. The end fins 42 are greatly bent upward. Therefore, the air flowing in the lower part of the ventilation path 24 passes through the shut damper 80 and the upstream fin group 60 and then is guided obliquely upward by the bent portion 54, then flows along the main body portion 53, and obliquely passes through the opening 23 a. Blow down.

  In the case of the above tilting, if the support shaft 45 is provided at a location different from the downstream end in the direction along the ventilation path 24 in the intermediate fin 43 and the end fins 41 and 42, the intermediate fin 43 and the end fin 41. , 42 is tilted, a portion downstream of the support shaft 45 is displaced and the appearance is impaired. However, in this embodiment, the support shaft 45 is provided at the downstream end in the direction along the ventilation path 24, and even if the intermediate fin 43 and the end fins 41 and 42 are tilted, the downstream portion thereof is not displaced.

According to the embodiment described in detail above, the following effects can be obtained.
(1) As shown in FIG. 3, the end fins 41 and 42 at both ends of the downstream fin group 40 are disposed in the vicinity of the second wall portions 28 and 29.

  Therefore, although the retainer 20 is thin with a small size in the arrangement direction (up and down direction) of the downstream fins, the end fins 41 and 42 are disposed at locations far away from the second wall portions 28 and 29. In comparison, the interval between adjacent downstream fins can be increased. This is particularly effective not only when each downstream fin is made parallel to the ventilation direction but also when the downstream fin is inclined with respect to the ventilation direction. This is because the interval between adjacent downstream fins becomes narrower as the inclination angle with respect to the ventilation direction increases.

  In the case where the end fins 41 and 42 are arranged at positions far away from the second wall portions 28 and 29, when the downstream fins are greatly inclined with respect to the ventilation direction, the gap between the adjacent downstream fins It becomes difficult to secure a sufficiently wide flow path. However, in the present embodiment, since the interval between the downstream fins is increased by the above arrangement, even when the downstream fin is greatly inclined with respect to the ventilation direction, a sufficient space is provided between the downstream fins. Can be secured (see FIGS. 7 and 8).

  (2) In relation to the above (1), in the present embodiment, only the three downstream fins such as the pair of upper and lower end fins 41 and 42 and the one intermediate fin 43 disposed therebetween are used as the downstream side. The fin group 40 is comprised. Therefore, the space | interval between adjacent downstream fins can be enlarged efficiently, ensuring a wind direction adjustment function, and a flow path can be ensured.

  (3) The end fins 41 and 42 are configured to include main body portions 51 and 53 and bent portions 52 and 54, and movement allowance portions 34 and 36 are provided in the vicinity of the second wall portions 28 and 29. Therefore, by changing the position of the upstream end of the bent portions 52 and 54 in the movement allowing portions 34 and 36, the tilting of the main body portions 51 and 53 with the support shaft 45 as a fulcrum and the bending of the bent portions 52 and 54 are performed. The direction of the air blown out from the opening 23a of the retainer 20 can be changed by changing the degree of bending of the end fins 41 and 42.

  Further, the movement of the upstream ends of the bent portions 52 and 54 by the movement allowing portions 34 and 36 is performed in a state where the second wall portions 28 and 29 are approached. Therefore, it is possible to suppress the generation of a space between the upstream ends of the bent portions 52 and 54 and the second wall portions 28 and 29, and to suppress the generation of noise and an increase in pressure loss due to the space.

  (4) In each of the end fins 41 and 42, the bent portions 52 and 54 are connected to the upstream ends of the main body portions 51 and 53 by a shaft 55 so as to be rotatable. Therefore, in each of the end fins 41 and 42, the bent portions 52 and 54 can be bent with respect to the upstream ends of the main body portions 51 and 53 by rotating the bent portions 52 and 54 around the shaft 55.

  (5) As the movement allowance portions 34 and 36, a configuration is adopted in which the groove portions 38 extending along the ventilation direction are adopted at the boundary portions between the first wall portions 26 and 27 and the second wall portions 28 and 29. A pin 56 protruding from the upstream end of the side surfaces of the bent portions 52 and 54 is engaged with the groove portion 38. Therefore, by moving the pin 56 in the groove portion 38, the upstream ends of the bent portions 52 and 54 are in the state of approaching the second wall portions 28 and 29 regardless of the position of the pin 56 and vice versa. It can be moved in the direction.

  (6) In the air conditioning thin register 97 described in Patent Document 1, the downstream divided piece 103b (105b) of the fin 103 (105) positioned on the same side as the tilt direction of the fin 104 is parallel to the ventilation path 98. It is kept in a proper state. Therefore, the air flowing in the vicinity of the fin 103 (105) is blown out straight from the blowout port 99. Even if the occupant tilts the intermediate fin 104 so as to become higher toward the downstream side as shown in FIG. 13 in order to change the air blowing direction, from the upper part of the air outlet 99 of the air conditioning thin register 97, The wind blows in different directions. Contrary to the above, the same phenomenon occurs when the fin 104 is tilted so as to become lower toward the downstream side.

  In this regard, in the first embodiment, the downstream portions of the end fins 41 and 42 are constituted by flat plate-like main body portions 51 and 53. The link mechanism 50 using the connecting rod 48 or the like maintains the main body portions 51 and 53 in a state that is always parallel to the intermediate fin 43 regardless of the tilt angle of the intermediate fin 43. Therefore, the air flowing through the upper portion of the ventilation path 24 and the air flowing through the lower portion can be blown out in the same direction as the air flowing through the intermediate portion in the height direction.

  (7) The end fins 41 and 42 and the intermediate fin 43 are supported on the first wall portions 26 and 27 so as to be tiltable by the support shaft 45 provided at the downstream end in the direction along the ventilation path 24. Therefore, when these end fins 41 and 42 and the intermediate fin 43 are tilted, the downstream portion thereof is prevented from being displaced, and the appearance can be improved.

  (8) A cover 23 having an opening 23a smaller than the opening 22b of the main body 22 is attached to the main body 22 from the downstream side. Therefore, the cover 23 can conceal the opening 22b of the main body 22 and the downstream ends of the end fins 41 and 42, thereby further improving the design.

Note that the present invention can be embodied in another embodiment described below.
-In the end fins 41 and 42, you may connect the bending parts 52 and 54 with the main-body parts 51 and 53 so that bending is possible in the aspect different from the said embodiment. An example is shown in FIGS. In this example, a hard polymer material (synthetic resin or the like) is used as the material of the main body portions 51 and 53, and a soft polymer material (rubber, elastomer, or the like) is used as the material of the bent portions 52 and 54 (soft material). It is used. Then, by using these different materials (materials) and performing double molding (two-color molding), the bent portions 52 and 54 are integrally formed in a state of being fixed to the upstream ends of the main body portions 51 and 53. ing.

  In the thin air-conditioning register 15 in which the end fins 41 and 42 are incorporated, the bent portions 52 and 54 can be bent with respect to the upstream ends of the tilted main body portions 51 and 53 by elastic deformation. Therefore, in each of the end fins 41 and 42, the position of the pin 56 in the groove portion 38 of the movement allowance portions 34 and 36 is changed, so that the main body portions 51 and 53 are tilted around the support shaft 45, and the bent portions 52 and 54 elastic deformation is allowed. The bending degree of the end fins 41 and 42 is changed by the tilting of the main body parts 51 and 53 and the elastic deformation of the bending parts 52 and 54.

  Therefore, even when the configuration of the end fins 41 and 42 is changed as described above, the same operation and effect as the above-described embodiment can be obtained. In addition, since the bent portions 52 and 54 are elastically deformed so as to swell in the same direction as the tilting direction of the main body portions 51 and 53, there is an advantage that the air flowing direction can be changed smoothly.

  The present invention can also be applied to an air-conditioning thin register in which the opening 23a (outlet) is arranged in a vertically long shape. In this case, in the retainer 20, the wall portions facing each other in the vertical direction become the first wall portions 26 and 27, and the wall portions facing each other in the vehicle width direction become the second wall portions 28 and 29. The downstream fins (end fins 41 and 42 and intermediate fins 43) are arranged in the vehicle width direction, and the upstream fins 61 are arranged in the vertical direction.

The present invention can also be applied to an air conditioning thin register in which the downstream fin group 40 includes end fins 41 and 42 and an intermediate fin 43 and other downstream fins.
-About the upstream fins 61, the shut damper 80, etc., members, places, etc. that are not directly related to the characteristic part of the present invention may be appropriately changed such as omitting or changing the shape, number, etc. Good.
