Description

  The present invention relates to a register used for an air outlet that blows out air-conditioned air for ventilating an automobile or air-conditioning a building.

  2. Description of the Related Art Conventionally, for example, there is a register that is used in an air outlet that is arranged on an instrument panel of an automobile and blows out conditioned air adjusted by an air conditioner into the vehicle (for example, Patent Document 1). The register described in Patent Document 1 includes a retainer, a downstream fin, a plurality of upstream fins, an operation knob, and the like. The downstream fin is provided so as to be rotatable with respect to the retainer. The plurality of upstream fins are provided on the upstream side of the downstream fin in the blowing direction of the conditioned air, and are provided so as to be rotatable with respect to the retainer. Each of the plurality of upstream fins is provided with a connecting convex portion. The plurality of upstream fins rotate in conjunction with each other by connecting the connecting convex portions with the connecting rod.

  The operation knob includes an operation unit and an arm (in the literature, a fork unit). The operation portion has a thin, substantially box shape, is inserted through the downstream fin, and is slidable with respect to the downstream fin. The arm is provided at the upstream end of the operation unit, and connects the operation unit and the upstream fin. The arm extends in a bifurcated manner toward the upstream, and is in a state of sandwiching a transmission shaft provided in the central upstream fin. The arm transmits a force applied to the operation portion when operating the operation knob to the upstream fin, and rotates the central upstream fin. The plurality of upstream fins rotate other upstream fins by the connecting rod in accordance with the rotation of the central upstream fin.

  Further, the plurality of upstream fins and downstream fins of Patent Document 1 are not orthogonal to each other but intersect at a predetermined angle. More specifically, the downstream fin is extended in the left-right direction. On the other hand, the plurality of upstream fins extend in a direction inclined with respect to the left and right directions and the up and down direction which is the thickness direction of the downstream fins. Further, in such a register in which the upstream fin is inclined with respect to the downstream fin, when the operation knob is operated in the vertical direction in order to change the direction of the downstream fin, the arm moves in the vertical direction together with the downstream fin. Rotate. At this time, the arm and the transmission shaft inserted between the bifurcated arm come into contact with each other, and there is a possibility that the vertical rotation of the arm is hindered by the transmission shaft. As a result, the operability of the operation knob may be reduced.

  On the other hand, the arm of patent document 1 is attached so that rotation with respect to the operation part is possible. The arm is pivotable about a central axis along a direction from upstream to downstream. When the operation knob is moved in the vertical direction, the arm contacts the transmission shaft, but rotates with respect to the operation portion to reduce interference with the transmission shaft.

Japanese Patent Laying-Open No. 2015-78787

  However, in the register of Patent Document 1 described above, in order to suppress the interference between the arm and the transmission shaft, that is, the deterioration of the operability of the operation knob, it is necessary to have a structure in which the arm can be rotated with respect to the operation unit. is there. For this reason, there exists a possibility of causing complication of a structure, for example, it becomes necessary to comprise an arm with a member different from an operation part. As a result, it is necessary to provide a bearing portion for supporting the arm in the operation portion, or to assemble the arm to the operation portion, which may lead to a complicated manufacturing process.

  The present invention has been made to solve the above-described problems, and is a register in which an upstream fin is inclined with respect to a downstream fin, and the operability of the operation knob is simplified while simplifying the structure. It is an object of the present invention to provide a register that can improve the performance.

  The present application has a cylindrical shape, a retainer that blows conditioned air in the blowing direction, and a flat plate extending in a direction that intersects the blowing direction of the conditioned air, and is supported rotatably with respect to the retainer. The downstream fin is disposed at a position upstream of the downstream fin in the air blowing direction, extends in a direction intersecting the air blowing direction, and the downstream fin extending direction and the downstream A plurality of upstream fins extending in an inclined direction inclined with respect to two directions of the thickness direction of the side fins and rotatably supported with respect to the retainer, and a plurality of insertion holes are formed, An insertion member provided in each of the upstream fins is inserted into each of the plurality of insertion holes to rotate the plurality of upstream fins in conjunction with each other, and the downstream fin is rotated in the thickness direction. Maneuver to move A knob, and the operating knob is slidably attached to the downstream fin in the extending direction, and one upstream fin and the operating part among the plurality of upstream fins. And a plurality of insertion holes provided in the interlocking member, each having a connecting portion that rotates the one upstream fin as the operating portion slides in the extending direction. The target insertion hole, which is the insertion hole into which the insertion part of the one upstream fin is inserted, is connected to the connection part from the operation part when the downstream fin is rotated in the thickness direction. The register is formed according to the direction in which the insertion portion moves by applying an external force to the one upstream fin through the rotation of the one upstream fin and rotating the one upstream fin.

  According to the register of the present application, the target insertion hole is formed according to the moving direction of the insertion portion, the insertion portion is easily moved in the target insertion hole, and one upstream fin is rotated independently. Since only one upstream fin is rotated without rotating the other upstream fins, the force required to move the operation knob can be reduced. As a result, the operability of the operation knob can be improved. Furthermore, when the downstream fin is rotated in the thickness direction, only one upstream fin can be rotated. For this reason, unlike the prior art, it is not necessary to have a complicated structure such as a connecting portion such as a structure in which the arm can be rotated in order to suppress the rotation of all the upstream fins. The number of parts of the operation knob can be reduced, the manufacturing process can be simplified, and the manufacturing cost of the register can be reduced. Therefore, in the register, the operability of the operation knob can be improved while simplifying the structure.

And shows a state in which the air-conditioning air blowing direction is not changed (hereinafter sometimes referred to as a neutral state).

(Configuration of register 10)
FIG. 1 is a front view of the register 10 of the present embodiment. FIG. 2 is an external perspective view of the register 10. 3 is a cross-sectional view showing a cross section taken along line AA shown in FIG. FIG. 4 is a cross-sectional view showing a cross section taken along line BB shown in FIG. As shown in FIGS. 1 to 4, the register 10 includes a retainer 11, a bezel 13, a plurality of downstream fins 15, a plurality of upstream fins 17, a damper plate 19, and the like.

  The retainer 11 has a cylindrical shape extending in the front-rear direction. A ventilation path 21 is formed inside the retainer 11 (see FIG. 3). The rear end of the retainer 11 is connected to an air conditioner (not shown). The bezel 13 is formed with an elongated air outlet 31 that is long in the left-right direction. The retainer 11 has a cylindrical shape that communicates with the air outlet 31 of the bezel 13 and blows conditioned air in a blowing direction 22 that is a direction toward the air outlet 31. The ventilation path 21 (retainer 11) has a substantially rectangular shape in which a cross-sectional shape cut by a plane orthogonal to the blowing direction 22 is long in the left-right direction.

  As shown in FIG. 4, the retainer 11 has a cylindrical shape bent in a direction that forms a predetermined angle with respect to the front-rear direction (in the present embodiment, diagonally left rearward). Thereby, the conditioned air flowing in the ventilation direction 21 in the ventilation path 21 can be applied to the bent inner wall of the retainer 11 and accelerated. As a result, the accelerated conditioned air is applied to the upstream fin 17 described later, and the directivity of the conditioned air in the left-right direction is enhanced.

  A damper plate 19 is provided in the ventilation path 21 of the retainer 11 on the rear side (upstream side) of the upstream fin 17. The damper plate 19 is rotatably provided on the retainer 11 and rotates to open and close the ventilation path 21 to supply or stop the conditioned air. The damper plate 19 is formed in accordance with the shape of the ventilation path 21 and has a substantially rectangular plate shape that is long in the left-right direction in the state shown in FIGS. 3 and 4 (open state). That is, the damper plate 19 has a rectangular shape that matches the cross-sectional shape of the ventilation path 21. The register 10 of the present embodiment includes an operation dial 23 for rotating the damper plate 19 on the right side portion of the bezel 13. The operation dial 23 is connected to the damper plate 19 by a link mechanism 24. As a result, the vehicle occupant can rotate the damper dial 19 and open / close the ventilation path 21 by rotating the operation dial 23. FIG. 4 shows only a part of the link mechanism 24.

  As shown in FIGS. 1 to 4, the bezel 13 is a member disposed on the front surface of the retainer 11. The bezel 13 is attached to a downstream opening 25 (see FIG. 3) that is an opening on the front side (downstream side) of the retainer 11. The bezel 13 is a member such as a frame that is formed with an air outlet 31 having a size matching the downstream opening 25 and covers the periphery of the downstream opening 25 from the front. The bezel 13 is fixed to the retainer 11 by engaging the hole of the engaged portion 32 (see FIG. 2) with the protrusion of the engaging portion 27 of the retainer 11. For example, two engaged portions 32 of the present embodiment are provided on each of the upper edge portion and the lower edge portion of the bezel 13. In accordance with this, two engaging portions 27 are provided on each of the upper edge portion and the lower edge portion of the retainer 11. The air outlet 31 is a hole that blows out the conditioned air that is adjusted by the air conditioner and flows through the ventilation path 21 toward the outside of the register 10 (on the side of a user such as an occupant). The air outlet 31 of the present embodiment has an elongated shape that is long in the left-right direction and short in the up-down direction, and has a narrow width in the up-down direction at the left side portion (see FIG. 1).

(Configuration of downstream fin 15)
The plurality of downstream fins 15 are disposed on the inner side of the air outlet 31 of the bezel 13 (the connection portion between the bezel 13 and the retainer 11), and are downstream (front side) as compared with the position of the upstream fins 17 in the air blowing direction 22. It is arranged at the position. The register 10 of the present embodiment is provided with, for example, three downstream fins 15. The plurality of downstream fins 15 have a flat plate shape extending in the left-right direction (an example of the extending direction) that intersects the air blowing direction 22, and is supported so as to be rotatable with respect to the retainer 11. The plurality of downstream fins 15 are arranged side by side in the vertical direction, which is the thickness direction. In the following description, among the three downstream fins 15, the downstream fin 15 disposed at the center in the vertical direction is referred to as a downstream fin 15 </ b> A when distinguished from other downstream fins 15. .

  The length in the left-right direction of the plurality of downstream fins 15 is a length that matches the shape of the air outlet 31. For example, the length of the downstream fin 15 in the left-right direction is shortened from the upper downstream fin 15 toward the lower downstream fin 15. The downstream fin 15 has a plate shape extending along the left-right direction while keeping the width in the front-rear direction substantially constant. In the neutral state, the downstream fin 15 is in a state where the plane is orthogonal to the vertical direction. The plurality of downstream fins 15 are arranged in parallel to each other with their planes facing each other in the up-down direction (the thickness direction of the downstream fins 15).

  As shown in FIG. 3, the front surface of the register 10 according to the present embodiment is inclined forward as it goes from above to below, and the lower end protrudes forward compared to the upper end. This enhances the design of the register 10 as viewed from the front (vehicle compartment side). Further, the three downstream fins 15 are arranged on the front side as they become the lower downstream fins 15.

  As shown in FIG. 4, fin shafts 41 are formed on both sides of the downstream fin 15 in the left-right direction. The fin shaft 41 is formed so as to protrude outward from the outer peripheral surface of the downstream fin 15 in the left-right direction. The fin shaft 41 is provided on the front side of the downstream fin 15 in the front-rear direction. The rotation axis of each fin shaft 41 is a direction along the left-right direction. The fin shaft 41 is inserted into an insertion hole 43A formed in the bearing member 43 held by the bezel 13 and the retainer 11, and is attached to the bearing member 43 (bezel 13 and retainer 11) so as to be rotatable. . Each of the downstream fins 15 is rotatable about the axial direction of the fin shaft 41, that is, is rotatable upward and downward about the axial direction along the left-right direction.

  Further, a regulation shaft 45 and a connection shaft 46 are provided on the right end surface of the downstream fin 15. The restriction shaft 45 is provided on the rear side of the fin shaft 41. The connecting shaft 46 is provided on the rear side of the regulating shaft 45. The connecting shaft 46 is for connecting the plurality of downstream fins 15 to each other, and is provided on each downstream fin 15. The connecting shaft 46 is formed to protrude outward from the right end surface of each of the downstream fins 15. Each connecting shaft 46 is inserted into the insertion hole of the connecting rod 47 and is held by the connecting rod 47. Thereby, the plurality of downstream fins 15 are connected to each other by the connecting shaft 46 and the connecting rod 47. When any downstream fin 15 among the plurality of downstream fins 15 rotates, the other downstream fin 15 rotates via the connecting rod 47.

  Further, the restriction shaft 45 is for determining the rotation range of the downstream fin 15 and is provided only in the central downstream fin 15A, for example. The restriction shaft 45 is formed to protrude outward from the right end surface of the downstream fin 15A. The restriction shaft 45 is movable in the vertical direction within an insertion hole 43 </ b> B provided in the bearing member 43. The insertion hole 43B is a groove formed with a predetermined length in the vertical direction. The restriction shaft 45 moves upward or downward and engages with the inner wall of the insertion hole 43B to restrict the rotation of the downstream fin 15A. The downstream fin 15A is rotatable in the vertical direction within a range in which the restriction shaft 45 can move within the insertion hole 43B. Thereby, the rotation range of all the downstream fins 15 connected by the connecting rod 47 is defined by the restriction shaft 45 and the insertion hole 43B.

  3 and 4, an operation knob 51 is attached to the central downstream fin 15A. The operation knob 51 includes an operation unit 53 and an arm 54. The operation portion 53 has a box shape that is long in the left-right direction and thin in the up-down direction, and has a through-hole 53A that penetrates in the left-right direction. The operation part 53 is attached so that the downstream fin 15A is inserted into the through hole 53A and is slidable in the left-right direction with respect to the downstream fin 15A. In the register 10 of the present embodiment, the downstream fin 15A can be rotated in the vertical direction by operating the operation portion 53 of the operation knob 51 in the vertical direction. Then, the rotation of the downstream fin 15 </ b> A is transmitted to the other downstream fin 15 via the connecting shaft 46 and the connecting rod 47. As a result, the three downstream fins 15 rotate in the vertical direction in conjunction with each other. The blowing direction of the conditioned air blown from the air outlet 31 is adjusted in the vertical direction.

  A support member 55 is built in the operation portion 53 on the front side of the downstream fin 15A. The support member 55 positions the operation unit 53 in the front-rear direction. In addition, the operation portion 53 moves in the left-right direction by engaging the inner wall of the through hole 53A with an engagement portion 49 (see FIG. 4) formed in the center portion of the downstream fin 15A in the left-right direction. Regulated within a certain range. An arm 54 is fixed to the rear end surface of the operation unit 53. The arm 54 extends in a bifurcated manner from the front side, which is a connecting portion with the operation unit 53, toward the rear side (upstream side).

(Configuration of upstream fin 17)
As shown in FIGS. 1 and 3, a plurality of (in this embodiment, five) upstream fins 17 are arranged inside the downstream opening 25 of the retainer 11. The plurality of upstream fins 17 are disposed on the rear side (upstream side) of the downstream fins 15. Each upstream fin 17 is inclined at a predetermined angle with respect to two directions of the extending direction of the downstream fin 15 (left and right direction in the present embodiment) and the thickness direction of the downstream fin 15 (vertical direction in the present embodiment). It extends in a tilting direction 61 (see FIG. 1). The inclination direction 61 is a direction that intersects the blowing direction 22. Each upstream fin 17 is in a state where a substantially plate-like member having a plane along the vertical direction and the front-rear direction is inclined at a predetermined angle (inclination angle of the inclination direction 61). The upstream fins 17 of the present embodiment are disposed at positions where the upper end portion is shifted to the left as compared with the lower end portion, and are in an inclined state. In the neutral state, the respective upstream fins 17 are arranged in parallel with each other with their planes facing each other in the thickness direction (a direction orthogonal to the tilt direction 61).

  Of the plurality of upstream fins 17, the upstream fin 17 (an example of one upstream fin) disposed at the center in the left-right direction is connected to the arm 54 of the operation knob 51. In the following description, among the five upstream fins 17, the upstream fin 17 disposed at the center in the left-right direction is referred to as an upstream fin 17 </ b> A when distinguished from other upstream fins 17. .

  FIG. 5 is a front view of the central downstream fin 15A and the plurality of upstream fins 17 as viewed from the front. FIG. 6 is a rear view of the central downstream fin 15A and the plurality of upstream fins 17 as viewed from the rear. FIG. 7 is an exploded perspective view of the upstream fin 17. FIG. 8 is a top view of the central downstream fin 15A and the plurality of upstream fins 17 as viewed from above. As shown in FIGS. 5 to 8, the upstream fin 17 </ b> A has a transmission shaft 63 connected to the arm 54. The upstream fin 17 </ b> A has a predetermined thickness in the left-right direction and has a substantially plate shape extending in the inclined direction 61. The transmission shaft 63 is provided at an end portion on the front side (downstream side) of the upstream fin 17 </ b> A and has a substantially bar shape extending along the inclined direction 61. A semicircular cutout portion 64 is formed on the rear side of the transmission shaft 63 and protrudes toward the rear side when viewed from the left-right direction. Therefore, the transmission shaft 63 is separated from the other part of the upstream fin 17A by the notch 64 in the front-rear direction.

  The transmission shaft 63 has a substantially bar shape with a constant width in the front-rear direction and the left-right direction. Both ends of the transmission shaft 63 in the inclined direction 61 are connected to the main body portion of the upstream fin 17A. Engagement plates 65 projecting in the left-right direction and the front-rear direction from the upstream fin 17A are formed at both ends of the transmission shaft 63 in the inclined direction 61. The engagement plates 65 are formed at both ends of the transmission shaft 63 in the tilt direction 61. The engagement plate 65 engages with the arm 54 that moves in the vertical direction as the operation knob 51 rotates in the vertical direction, and restricts the movement of the arm 54 in the tilt direction 61.

  The arm 54 of the operation knob 51 extends from the rear end portion of the operation portion 53 to the rear, and is provided so as to sandwich the transmission shaft 63 of the upstream fin 17A from the left and right directions. As shown in FIG. 6, the bifurcated portions of the arm 54 are opposed to each other with a predetermined gap in the left-right direction. The transmission shaft 63 is inserted into the gap of the arm 54 obliquely (along the tilt direction 61). Accordingly, the upstream fin 17 </ b> A transmits the external force that rotates in the left-right direction via the arm 54 and the transmission shaft 63 in accordance with the slide movement of the operation unit 53 in the left-right direction. The other upstream fins 17 other than the central upstream fin 17A have substantially the same structure as the central upstream fin 17A except for the transmission shaft 63, the notch 64, and the engagement plate 65. For this reason, in the description of the other upstream fins 17, the same parts as the upstream fins 17A are omitted as appropriate.

  An upper rotation support shaft 71 is provided at the upper end of each upstream fin 17 and at the center in the front-rear direction. The upper rotation support shaft 71 protrudes upward from the upper end surface of the upstream fin 17. Similarly, a lower rotation support shaft 72 is provided at the lower end of each upstream fin 17 and at the center in the front-rear direction. The lower rotation support shaft 72 protrudes downward from the lower end surface of the upstream fin 17. The upper turning support shaft 71 is inserted into the insertion hole 73A (see FIG. 3) of the bearing member 73 (see FIG. 7) attached to the upper portion of the downstream opening 25 of the retainer 11, and rotates with respect to the bearing member 73. It is mounted movably. The bearing member 73 is attached to the retainer 11 by inserting an insertion portion (not shown) of the retainer 11 into an engagement hole 73B (see FIG. 7) provided on the upper surface. The bearing member 73 is attached to the retainer 11 by engaging two protrusions 73 </ b> C provided on the upper surface with an engaged portion (not shown) of the retainer 11. Accordingly, the upper rotation support shafts 71 of the plurality of upstream fins 17 are rotatably held by the retainer 11 via the bearing members 73.

  Similarly, the lower rotation support shaft 72 is inserted into the insertion hole 74A of the bearing member 74 attached to the lower portion of the downstream opening 25 of the retainer 11, and is rotatably attached to the bearing member 74. Yes. Similar to the bearing member 73, the bearing member 74 has an engagement hole and a protrusion (both not shown) on the lower surface, and is attached to the retainer 11 by the engagement hole and protrusion. Accordingly, the lower rotation support shafts 72 of the plurality of upstream fins 17 are rotatably held by the retainer 11 via the bearing members 74.

  Accordingly, each of the upstream fins 17 is held by the retainer 11 and can be rotated in the left-right direction around a rotation axis connecting the upper rotation support shaft 71 and the lower rotation support shaft 72. The rotation axes of the upper rotation support shaft 71 and the lower rotation support shaft 72 are in a direction along the tilt direction 61. Further, the upstream fin 17 of the present embodiment has an upper end disposed rearward compared to the lower end, and when viewed from the left-right direction, the rotation axis is predetermined in a counterclockwise direction in FIG. 3 from a position along the vertical direction. It is in a state rotated by an angle. Therefore, the upstream fins 17 are disposed so as to be rotatable with the upper portion inclined to the rear side. The upstream fin 17 may have a configuration in which the upper portion and the lower portion are not displaced in the front-rear direction when viewed from the left-right direction.

  In addition, an insertion portion 76 that protrudes upward is formed on the upper end surface of each upstream fin 17 on the rear side. The length of the upstream fin 17 along the inclined direction 61 is longer in the portion where the upper rotation support shaft 71 is formed than in the portion where the insertion portion 76 is formed. In other words, the insertion portion 76 is formed on the rear side in the inclined direction 61 as compared with the position of the upper rotation support shaft 71 and at a portion lowered by one step. The insertion portion 76 of each upstream fin 17 is inserted into the insertion hole 78 of the connecting rod 77 (an example of an interlocking member). The plurality of upstream fins 17 are connected to each other by inserting the insertion portion 76 into the insertion hole 78 of the connecting rod 77.

  Therefore, in the register 10 of the present embodiment, the central upstream fin 17A can be rotated in the left-right direction via the arm 54 by operating the operation portion 53 of the operation knob 51 in the left-right direction. The rotation of the upstream fin 17 </ b> A is transmitted to the other upstream fin 17 via the insertion portion 76 and the connecting rod 77. When the central upstream fin 17A rotates in response to the slide movement of the operation knob 51, the other upstream fins 17 rotate in the left-right direction in conjunction with the central upstream fin 17A. Therefore, in the register 10 of this embodiment, the operating knob 51 is slid to rotate all the upstream fins 17 in the left-right direction, thereby changing the blowing direction of the conditioned air blown from the air outlet 31. It can be adjusted in the horizontal direction.

(About connecting rod 77)
Next, the connecting rod 77 of this embodiment will be described in detail. FIG. 9 shows a perspective view of the connecting rod 77 and a partially enlarged view of the connecting rod 77. FIG. 10 shows a top view of the connecting rod 77. As shown in FIGS. 9 and 10, the connecting rod 77 has a plate shape that is thin in the vertical direction and long in the horizontal direction. The orthogonal direction of the plane of the connecting rod 77 is a direction along the vertical direction. The connecting rod 77 has a substantially constant width in the front-rear direction and extends in the left-right direction. Insertion holes 78 are formed in the connecting rod 77 at equal intervals in the left-right direction, which is the extending direction. In other words, the connecting rod 77 has a flat plate shape extending in the left-right direction in which the plurality of upstream fins 17A (insertion portions 76) are arranged. Five insertion holes 78 are formed in accordance with the number of the upstream fins 17. In the following description, when the insertion hole 78 (an example of the target insertion hole) arranged in the center in the left-right direction among the five insertion holes 78 is distinguished from the other insertion holes 78, the target insertion hole 78A Will be described.

  The insertion hole 78 is formed through the connecting rod 77 in the thickness direction. The cross-sectional shape of the other insertion holes 78 excluding the target insertion hole 78A is a substantially circular shape that matches the shape of the insertion portion 76 of the upstream fin 17. The insertion portion 76 of the upstream fin 17 excluding the upstream fin 17A is inserted into each of the insertion holes 78 except the target insertion hole 78A and is rotatably held. The connecting rod 77 is provided with a protrusion 81 that protrudes rearward from the side edge on the rear side. The protrusion 81 functions as a mark for suppressing the connecting rod 77 from being assembled by mistake.

  Here, the upstream fins 17 and the downstream fins 15 of the present embodiment are not orthogonal to each other but intersect at a predetermined angle. Further, in the register 10 in which the upstream fin 17 is inclined with respect to the downstream fin 15, when the operation knob 51 is operated in the vertical direction in order to change the direction of the downstream fin 15, 54 rotates in the vertical direction together with the downstream fin 15A. At this time, the arm 54 is rotated to change the position where the transmission shaft 63 is inserted, and may contact the transmission shaft 63 inserted between the two branches.

  Therefore, in the connecting rod 77 of the present embodiment, when the arm 54 and the transmission shaft 63 are inadvertently contacted, the target insertion hole 78A is provided with another object in order to rotate only the central upstream fin 17A. Compared to the insertion hole 78, it is formed to be expanded. The insertion portion 76 of the upstream fin 17A is inserted into the target insertion hole 78A. When the downstream fin 15 is rotated in the vertical direction (thickness direction), the target insertion hole 78A is given an external force from the operation portion 53 to the upstream fin 17A via the arm 54 (an example of a connecting portion). It is formed according to the direction in which the insertion portion 76 moves as the upstream fin 17A rotates.

  Specifically, FIG. 11 is a top view showing a state in which the upstream fin 17 rotates. The target insertion hole 78A is formed as an arcuate groove that is curved at a predetermined angle when the connecting rod 77 is viewed in plan. The width of the groove of the target insertion hole 78A is a width that matches the outer diameter (thickness) of the insertion portion 76 of the upstream fin 17A. The extension direction of the target insertion hole 78A is, for example, a direction along a locus 85 obtained by rotating the insertion portion 76 around the rotation center 83 of the upper rotation support shaft 71 of the upstream fin 17A. The insertion portion 76 of the upstream fin 17A is movable in the target insertion hole 78A.

  Further, as described above, the register 10 of the present embodiment is disposed on the instrument panel on the right front as viewed from the driver of the automobile, for example. For this reason, the target insertion hole 78A is formed so as to expand in the direction of increasing the swing width of the upstream fin 17A when the upstream fin 17 is swung leftward, that is, when swung to the driver side. . More specifically, in FIG. 11, the target insertion hole 78 </ b> A is expanded clockwise about the rotation center 83. As a result, the swing angle θ1 when the central upstream fin 17A is swung to the left from the neutral state to the maximum is larger than the swing angle θ2 of the other upstream fins 17.

  FIG. 12 is a view of the state in which the upstream fin 17 is swung to the left and the downstream fin 15A is swung upward as viewed from the front. When the downstream fin 15 </ b> A and the operation unit 53 are rotated upward, the arm 54 is rotated to change the position where the transmission shaft 63 is inserted, and comes into contact with the transmission shaft 63. For example, in the transmission shaft 63 of this embodiment, the width in the front-rear direction is larger than the width in the left-right direction. In this case, when the upstream fin 17A is swung to the left and right, the transmission shaft 63 rotates within the fork of the arm 54 and has a wider surface (a surface facing the left and right in the neutral state) on the front surface. Rotate to face side. For this reason, in the transmission shaft 63 having a large width in the front-rear direction, there is a high possibility that it will contact the arm 54 when the upstream fin 17A is swung in the left-right direction.

  On the other hand, in the connecting rod 77 of the present embodiment, the target insertion hole 78A is expanded in the direction in which the insertion portion 76 moves as the upstream fin 17A rotates. For this reason, even if the arm 54 and the transmission shaft 63 come into contact with all the upstream fins 17 swung to the left as shown in FIG. 12, the central upstream fin 17A has the insertion portion 76 and the target insertion. The restriction of the rotation by the hole 78A is suppressed. In other words, only the upstream fin 17A can be rotated by moving the insertion portion 76 in the target insertion hole 78A along the locus 85 shown in FIG. As a result, even if the transmission shaft 63 and the arm 54 contact or interfere with each other, only the central upstream fin 17A can be rotated, and the state can be maintained without rotating the other upstream fins 17.

  In addition, although FIG. 12 demonstrated the case where the upstream fin 17 was shaken to the left direction, it is not restricted to this. For example, when the target insertion hole 78A has a symmetrical structure, the same effect can be obtained even when the target insertion hole 78A is swung in the right direction. Even if the upstream fin 17 is not swung in the left-right direction, the arm 54 and the transmission shaft 63 may come into contact with each other by swinging the downstream fin 15A in the up-down direction. Also in this case, by expanding the target insertion hole 78A, only the upstream fin 17A can be rotated, and the state can be maintained without rotating the other upstream fins 17.

  Further, as shown in FIGS. 9 to 11, the connecting rod 77 is formed with a recess 87 in accordance with the rotational position of the upper rotation support shaft 71. As shown in FIG. 7, the upper rotation support shaft 71 is thick on the base end side in the tilt direction 61. For example, the thickness and shape are set in order to secure the strength of the upper rotation support shaft 71. On the other hand, the swing angle θ1 of the central upstream fin 17A is larger than the swing angle θ2 of the other upstream fins 17. For this reason, for example, when the upstream fin 17 </ b> A is swung to the maximum swing angle θ <b> 1, the thickened portion of the upper rotation support shaft 71 may come close to or come into contact with the connecting rod 77. . Accordingly, the connecting rod 77 of the present embodiment is formed with a recess 87 in accordance with the rotational position and shape of the upper rotation support shaft 71 so as not to contact a part of the upper rotation support shaft 71 of the upstream fin 17A. ing. As a result, even if the upstream fin 17A is swung to the swing angle θ1, by inserting a portion that may come into contact with the upper rotation support shaft 71 into the recess 87, the connection rod 77 and the upstream Contact with the side fins 17A can be suppressed.

  Moreover, as shown in FIG. 11, the plate width 89 in the front-rear direction (the blowing direction 22) of the connecting rod 77 is large in the portion where the target insertion hole 78A is formed. More specifically, the connecting rod 77 is formed with a thick portion 91 protruding forward (downstream) at the position of the front end of the target insertion hole 78A. For example, the thick portion 91 protrudes in the direction in which the target insertion hole 78A is expanded (the direction along the locus 85). The connecting rod 77 protrudes forward at the portion where the thick portion 91 is formed, and the plate width 89 is increased. Since the connecting rod 77 is formed with the thick portion 91, the strength of the portion where the target insertion hole 78A is formed is improved. The width of the inner wall of the target insertion hole 78A and the side edge portion on the front side of the connecting rod 77, that is, the width of the thick portion 91 is a predetermined length (for example, 1 mm) that can ensure the necessary strength of the connecting rod 77 ).

  Further, the connecting rod 77 is formed with a protrusion 93 for suppressing the rattling of the upstream fin 17. FIG. 13 is a front view of the connecting rod 77 and shows a state in which the lower surface of the protruding portion 93 is aligned in the left-right direction. As shown in FIG. 13, a protrusion 93 is formed on the lower surface 95 of the upper surface 94 and the lower surface 95 of the connecting rod 77 having a plate shape. The lower surface 95 is a surface facing the upper surface 97 (see FIG. 8) of the upstream fin 17 in the inclined direction 61. The upstream fins 17 of this embodiment are inclined in the inclination direction 61. Therefore, for example, a gap corresponding to the inclination angle of the upstream fin 17 is provided between the lower surface 95 of the connecting rod 77 arranged along the left-right direction and the upper surface 97 of the upstream fin 17 inclined in the inclination direction 61. Is formed.

  In the upstream fin 17 of the present embodiment, the position of the upper end is arranged at a position shifted to the left as compared with the position of the lower end. In this case, the distance between the upper surface 97 of the upstream fin 17 and the lower surface 95 of the connecting rod 77 becomes longer from the right side toward the left side. That is, the gap between the upper surface 97 and the lower surface 95 is wider on the left side than on the right side. For this reason, the protrusion part 93 of this embodiment becomes a shape which protruded below further toward the left side from the right side. Thereby, the clearance gap between the lower surface 95 and the upper surface 97 is filled, and the protrusion part 93 is made to contact the upper surface 97 at the time of rotation of the upstream fin 17, and the rattling of the upstream fin 17 can be suppressed.

  Incidentally, in the said embodiment, the upstream fin 17A is an example of one upstream fin. The arm 54 is an example of a connecting portion. The upper rotation support shaft 71 and the lower rotation support shaft 72 are examples of rotation shafts. The connecting rod 77 is an example of an interlocking member.

As mentioned above, according to above-mentioned embodiment, there exist the following effects.
(1) The register 10 of the present embodiment has a cylindrical shape, a retainer 11 that blows conditioned air in the blowing direction 22, and a flat plate that extends in a direction that intersects the blowing direction 22 of the conditioned air. The downstream fins 15 that are rotatably supported with respect to the air flow direction, are arranged at positions upstream of the positions of the downstream fins 15 in the air blowing direction 22, extend in a direction intersecting the air blowing direction 22, and It extends in an inclined direction 61 that inclines with respect to the extending direction of the downstream fin 15 (for example, the left-right direction) and the thickness direction of the downstream fin 15 (for example, the vertical direction), and rotates with respect to the retainer 11. A plurality of upstream fins 17 that are movably supported and a plurality of insertion holes 78 are formed, and an insertion portion 76 provided in each of the plurality of upstream fins 17 is inserted into each of the plurality of insertion holes 78. Upstream of Comprising a connecting rod 77 (interlocking member) for rotating in conjunction with the fins 17 with each other, an operating knob 51 for rotating the downstream fins 15 in the thickness direction. The operation knob 51 is attached to the downstream fin 15 so as to be slidable in the extending direction, and among the plurality of upstream fins 17, the upstream fin 17 </ b> A (one upstream fin) and the operation unit 53. And an arm 54 (connecting portion) that rotates the upstream fin 17A as the operating portion 53 slides in the extending direction. Of the plurality of insertion holes 78 provided in the connecting rod 77, the target insertion hole 78A, which is the insertion hole 78 into which the insertion portion 76 of the upstream fin 17A is inserted, rotates the downstream fin 15 in the thickness direction. At this time, an external force is applied from the operation portion 53 to the upstream fin 17A via the arm 54, and the upstream fin 17A rotates to form the insertion portion 76 according to the moving direction.

  According to this, the plurality of upstream fins 17 rotate in conjunction with each other by inserting the insertion portion 76 into the insertion hole 78 of the connecting rod 77 (interlocking member). The downstream fin 15 rotates in the vertical direction when the operation knob 51 is operated. The operation portion 53 of the operation knob 51 is connected to the upstream fin 17A via the arm 54 (connection portion). The arm 54 rotates the upstream fin 17 </ b> A as the operation unit 53 slides. Thus, the connecting rod 77 rotates the other upstream fins 17 in conjunction with the rotation of the upstream fins 17A.

  Further, when the downstream fin 15 is rotated in the vertical direction, when the external force is applied to the upstream fin 17A from the operation portion 53 via the arm 54, the upstream fin 17A rotates. On the other hand, the target insertion hole 78A of the connecting rod 77 is formed in accordance with the direction in which the insertion portion 76 moves by rotating the upstream fin 17A when the downstream fin 15 is rotated. For this reason, the insertion portion 76 of the upstream fin 17A is easily moved in the target insertion hole 78A as the upstream fin 17A rotates. Thereby, the insertion portion 76 of the upstream fin 17 </ b> A is assumed to move relative to the connecting rod 77, and no force is transmitted to the connecting rod 77. As a result, although the upstream fin 17 </ b> A rotates, the other upstream fins 17 do not rotate in conjunction with each other because the force is not transmitted by the connecting rod 77.

  Here, suppose that the target insertion hole 78A is not formed according to the moving direction of the insertion portion 76. In this case, when the downstream fin 15 is rotated in the vertical direction, the arm 54 contacts, for example, the upstream fin 17A in which the position of the insertion portion 76 is fixed in the target insertion hole 78A. The arm 54 rotates the upstream fins 17 </ b> A and rotates the other upstream fins 17 via the connecting rod 77, that is, all the upstream fins 17 are rotated. As a result, a larger force (external force) is required to move the operation knob 51, and the operability of the operation knob 51 is reduced. On the other hand, in the register 10 of the present embodiment, the target insertion hole 78A is formed according to the moving direction of the insertion portion 76 to facilitate the movement of the insertion portion 76 in the target insertion hole 78A, and the upstream fin 17A is used alone. Rotate with. Since only the upstream fin 17A is rotated without rotating the other upstream fins 17, the force required to move the operation knob 51 can be reduced. As a result, the operability of the operation knob 51 can be improved.

  Furthermore, when the downstream fin 15 is rotated in the vertical direction, only the upstream fin 17A is rotatable. Therefore, unlike the prior art, it is not necessary to have a complicated structure such as a connecting portion such as a structure in which the arm 54 is rotatable in order to suppress the rotation of all the upstream fins 17. The number of parts of the operation knob 51 can be reduced, the manufacturing process can be simplified, and the manufacturing cost of the register 10 can be reduced. Therefore, in the register 10, the operability of the operation knob 51 can be improved while simplifying the structure.

(2) Further, the upstream fin 17A has an upper rotation support shaft 71 and a lower rotation support shaft 72 (rotation shaft) extending in the tilt direction 61, and the upper rotation support shaft 71 and the lower side. The support shaft 72 is rotatably supported by the retainer 11. The target insertion hole 78A is a groove formed in accordance with the size of the insertion portion 76. When the downstream fin 15 is rotated in the vertical direction, the upstream fin 17A is rotated. It is formed in a direction in which the insertion portion 76 circulates around the axial direction of the upper rotation support shaft 71 and the lower rotation support shaft 72.

  According to this, the target insertion hole 78A is formed in an arc shape in a direction in which the insertion portion 76 circulates around the upper rotation support shaft 71 and the like in the upstream fin 17A. In accordance with the rotation of the upstream fin 17A, the insertion portion 76 can move along the groove of the target insertion hole 78A. Thereby, only the upstream fin 17A can be rotated more reliably, and the operability of the operation knob 51 can be improved.

(3) Further, the connecting rod 77 has a recess 87 in accordance with the position close to the upper rotation support shaft 71 by rotating the upstream fin 17A when the downstream fin 15 is rotated in the vertical direction. Is formed.

  If the target insertion hole 78A is enlarged or the like, the swing angle θ1 that the upstream fin 17A rotates may be larger than the swing angle θ2 of the other upstream fin 17. As a result, the upper rotation support shaft 71 of the upstream fin 17A is more likely to contact the connecting rod 77 than the upper rotation support shaft 71 of the other upstream fin 17. Therefore, a recess 87 is provided in the connecting rod 77 at a position where there is a possibility of contact with the upper rotation support shaft 71 of the upstream fin 17A. Thereby, contact and interference with the upper rotation support shaft 71 of the upstream fin 17A and the connecting rod 77 can be suppressed, and the operability of the operation knob 51 can be improved by making the upstream fin 17A easy to rotate. Further, since it is not necessary to increase the distance between the upper turning support shaft 71 and the connecting rod 77, the register 10 can be reduced in size.

(4) Further, the connecting rod 77 has a flat plate shape extending in the direction in which the plurality of upstream fins 17 are arranged, and a plate width 89 that is a width in the blowing direction 22 of the conditioned air is formed with a predetermined size. The The plate width 89 of the portion where the target insertion hole 78A is formed is larger than the plate width 89 of the portion where the insertion hole 78 other than the target insertion hole 78A is formed.

  Here, from the viewpoint of reducing the weight of the connecting rod 77 and improving the operability of the operation knob 51, it is preferable to make the plate width 89 of the connecting rod 77 having a plate shape as small as possible. On the other hand, in the connecting rod 77 of the present embodiment, there is a possibility that the wall thickness (thickness around the target insertion hole 78A) in the portion where the target insertion hole 78A is formed becomes thin by expanding the target insertion hole 78A. is there. On the other hand, by increasing the plate width 89 of the portion where the target insertion hole 78A is formed, the thickness of the connecting rod 77 can be secured, and the strength of the portion where the target insertion hole 78A is formed can be secured. Moreover, the weight of the connecting rod 77 can be reduced by reducing the plate width 89 other than the portion where the target insertion hole 78A is formed. Thereby, it is possible to achieve both of ensuring the strength and improving the operability of the operation knob 51.

(5) Further, the lower surface 95 (plane) of the connecting rod 77 having a flat plate shape and the upper surface 97 (end surface) of the inclined direction 61 in each of the plurality of upstream fins 17 face each other in the inclined direction 61. . On the lower surface 95 of the connecting rod 77, a protruding portion 93 that protrudes toward the upper surfaces 97 of the plurality of upstream fins 17 is formed.

  A gap is formed between the lower surface 95 of the connecting rod 77 and the upper surface 97 of the upstream fin 17 according to the inclination angle of the upstream fin 17. The protruding portion 93 protrudes from the lower surface 95 of the connecting rod 77 toward the upper surface 97 of the upstream fin 17 and fills this gap. Thereby, the rattling which generate | occur | produces in the upstream fin 17 at the time of rotation etc. resulting from a clearance gap can be suppressed.

(6) Further, the transmission fin 63 extending in the inclined direction 61 is provided on the upstream fin 17A. The arm 54 is fixed to the upstream side of the operation knob 51 in the air blowing direction 22, extends in a bifurcated manner from the downstream to the upstream in the air blowing direction 22, and the transmission shaft 63 is sandwiched between the bifurcated bifurcated and the upstream Side fin 17A and operation part 53 are connected.

  According to this, the arm 54 is formed in a bifurcated shape that sandwiches the transmission shaft 63 of the upstream fin 17. The arm 54 fixed to the operation knob 51 rotates together with the downstream fin 15 (operation knob 51) when the downstream fin 15 is rotated in the vertical direction. There is a high possibility that the bifurcated portion and the transmission shaft 63 are in contact with each other and the upstream fin 17A is unintentionally rotated. For this reason, it is extremely effective to use the connecting rod 77 having the target insertion hole 78A expanded for such a bifurcated arm 54.

(7) In the register 10 of the present embodiment, the target insertion hole 78A is formed in accordance with the direction in which the insertion portion 76 moves when the upstream fin 17 is rotated toward the vehicle occupant.

  For example, when the register 10 is arranged on the right front side of the occupant, the occupant rotates the upstream fin 17 leftward when the conditioned air is blown in its own direction. At this time, the insertion portion 76 moves within the target insertion hole 78A. Only the central upstream fin 17A rotates, and the other upstream fins 17 maintain the rotational position. Therefore, the directivity of the conditioned air when the upstream fin 17 is directed toward the occupant can be more reliably maintained.

In addition, this application is not limited to embodiment mentioned above, Of course, various improvement and deformation | transformation are possible within the range which does not deviate from the summary of this application.
For example, the shape of the target insertion hole 78 </ b> A described above is an example, and can be appropriately changed according to the moving direction of the insertion portion 76. For example, as shown in FIG. 14, the target insertion hole 78A may be expanded in an arc shape not only in the right direction but also in the left direction. In this case, even when the upstream fin 17 is swung not only in the left direction but also in the right direction, the insertion portion 76 can be moved in the target insertion hole 78A and only the upstream fin 17A can be rotated. .
Further, the position and shape of the thick portion 91 may be changed according to the shape of the target insertion hole 78A. In the example shown in FIG. 14, the concave portion 87 is eliminated, and two thick portions 91 are provided on the connecting rod 77 in accordance with the expanded portion of the target insertion hole 78A that is symmetric.
Further, the interlocking member of the present application is not limited to a plate-like member such as the connecting rod 77 but may be a columnar shape or a cylindrical diameter shape.
Moreover, in the said embodiment, although the arm 54 was connected with the center upstream fin 17A, the structure connected with upstream fins 17 other than the center upstream fin 17A may be sufficient. That is, one upstream fin of the present application is not limited to the central upstream fin 17A.
Further, the connecting portion of the present application is not limited to the arm 54. For example, the downstream fin 15 and the upstream fin 17 may be connected by a gear mechanism. In this case, the target insertion hole 78A may be expanded in the direction in which the upstream fin 17 rotates by the external force of the gear mechanism.

Further, the connecting rod 77 does not have to include the recess 87.
Moreover, in the said embodiment, although the thick part 91 was formed in the connection rod 77 and the board width 89 of the connection rod 77 of the part in which the object insertion hole 78A was formed was enlarged, it is not restricted to this. The connecting rod 77 may not be provided with the thick portion 91 and may be formed with a constant plate width 89.
Further, the connecting rod 77 may not include the protruding portion 93.
Further, the connecting rod 77 may be provided below the upstream fin 17. Further, the connecting rod 77 may be provided both above and below the upstream fin 17.

In the above-described embodiment, the register 10 includes the plurality of downstream fins 15, but may be configured to include one downstream fin 15.
Further, the register 10 of the present application can be used not only as a register arranged in an instrument panel of a passenger compartment, but also as an air conditioning register arranged in another different place. That is, the register of the present application is widely applicable not only to automobiles but also to change the direction in which the conditioned air sent from an air conditioner or the like is blown out.
