  Hereinafter, a register according to the present invention will be described with reference to the drawings based on an embodiment in which the present invention is embodied. First, a schematic configuration of the register according to the first embodiment will be described with reference to FIGS.

  In FIG. 1 to FIG. 3, the register 1 includes a retainer 2 and a bezel 3. The retainer 2 is formed in a cylindrical shape having a substantially quadrangular cross section, and has an air vent 4 inside. The bezel 3 is attached to the front surface of the retainer 2, and the front surface is formed with a bezel opening 5 that blows air passing through the vent hole 4 of the retainer 2 to the outside of the register 1.

  A plurality of (four in FIG. 1 and FIG. 2) front fins 6 are provided in the vicinity of the bezel opening 5 of the bezel 3 so as to be integrally rotatable in the vertical direction via a link mechanism (not shown). Yes. The front fin 6 is rotated around the rotation shaft 11 by operating the operation knob 7 (attached to the center of the second front fin from the bottom) in the vertical direction, and from the bezel opening 5. The blowing direction of the blown-out air is changed up and down.

  A plurality of (five in FIG. 1 to FIG. 3) back fins 8 are disposed in the retainer 2 at positions behind the front fins 6 so as to be rotatable in the left-right direction. Each back fin 8 is configured to be able to rotate integrally through a link mechanism (not shown). By operating the operation knob 7 connected to the center back fin 8 in the left-right direction, The blowing direction of the blown air is changed to the left and right.

  The retainer 2 is attached to an instrument panel disposed at the front portion of a vehicle such as an automobile, and the rear portion of the retainer 2 is a duct disposed between the metal plate of the vehicle and the interior material. It is connected to the.

  In FIG. 3, the pair of side walls 9, 9 forming the vent hole 4 of the retainer 2 are close to the two back fins 8 </ b> A, 8 </ b> A located on both sides of the plurality of back fins 8, in a plan view. Triangular guide members 10 and 10 are formed so as to protrude toward the center of the retainer 2. Each of the guide members 10 and 10 guides the air passing through the ventilation port 4 of the retainer 2 toward the central portion of the retainer 2. That is, the air passing along the side walls 9 and 9 in the direction of the arrow A in the air vent 4 of the retainer 2 collides with the slopes 10A and 10A of the guide members 10 and 10, and the slopes 10A and 10A. Is guided in the direction of arrow B along As a result, the air passing along the side walls 9, 9 in the air vent 4 of the retainer 2 is guided toward the center of the retainer 2.

  The rotation shafts 11 and 11 of the two back fins 8A and 8A located on both sides of the plurality of back fins 8 correspond to the guide members 10 and 10, respectively. Specifically, the axis of the rotation shaft 11 of the two back fins 8A, 8A is an extension line L1 of the perpendicular L that is lowered from the triangular vertices 10B, 10B of the guide members 10, 10 toward the side walls 9, 9. Exists on. As described above, the axis of the rotation shafts 11 and 11 of each of the two back fins 8A and 8A located on both sides of the plurality of back fins 8 extends from the triangular vertex 10B of the guide member 10 to each side wall 9. Since it exists on the extended line L1 of the lowered perpendicular L, no matter how the two inner fins 8A, 8A are rotated, the inner fins 8A, 8A do not interfere with the guide member 10 at all. .

  Here, the rotation range in which each of the inner fins 8 can rotate around the rotation shaft 11 is, as shown in FIG. 3, the passage direction of air passing through the vent hole 4 of the retainer 2 (arrow A direction). It is set to about 40 degrees (the maximum directional angle of air with respect to the occupant is 23 degrees) from the parallel position (indicated by the solid line in FIG. 3) to both sides (left and right direction). When the two back fins 8A, 8A located on both sides of the plurality of back fins 8 are rotated to the maximum rotation angle as shown by the two-dot chain line in FIG. 3, the surface of the back fin 8A And the inclined surface 10A of the triangular guide member 10 are parallel to each other. Thus, when the two back fins 8A and 8A are rotated to the maximum, the inclined surface 10A of the triangular guide member 10 is parallel to the surface of the back fins 8A and 8A. Even when 8A is rotated to the maximum extent, the air passing through the vents 4 of the retainer 2 along the side walls 9 and 9 of the retainer 2 remains on the inclined surfaces 10A of the guide member 10 formed on the respective side walls 9 and It becomes possible to pass smoothly between the surfaces of the back fins 8A and 8A, and the air passing through the air vent 4 of the retainer 2 is not shielded. As a result, the air passing through the vent hole 4 of the retainer 2 passes smoothly along the rotational direction of the respective back fins 8A, 8A, and blows out from the bezel opening 5 of the bezel 3 with good directivity to the occupant. Is done.

  In the register 1 according to the first embodiment configured as described above, the front fin 6 is leveled and the back fin 8 is not rotated to the left or right (neutral state) and the front fin 6 is leveled. And wind speed distribution was measured in the state (back fin maximum rotation state) which rotated back fin 8 to the maximum rotation angle (40 degree | times). The measurement results are shown in the wind speed distribution diagram of FIG.

Here, the wind speed distribution was measured based on the following conditions.
(1) A contraction nozzle is connected to the air inlet of the retainer 2 on the side opposite to the bezel 3, and a constant amount of air is introduced into the retainer 2 from the airflow generator connected to the contraction nozzle. The wind speed distribution of the air blown out from the bezel opening 5 is measured.
(2) The air volume flowing into the retainer 2 was adjusted to 120 m ³ / h in the neutral state.
(3) The measurement was performed at a position of 750 mm from the register 1 along the blowing direction from the register 1 (a position corresponding to the chest of the passenger).

  As shown in FIG. 4A, in the neutral state, a concentric wind speed distribution was obtained in which the whole was substantially circular and the isobaric lines were relatively densely packed. This is because the air that has passed through the vent 4 of the retainer 2 flows through the gaps between the back fins 8 and the gaps between the front fins 6 as it is, and the air that passes along the side walls 9, 9 This is considered to be based on being guided and guided toward the central portion of the retainer 2 by the inclined surfaces 10A and 10A of the triangular guide members 10 and 10 formed on the side walls 9 and 9, respectively.

  Further, in the back fin maximum rotation state in which the back fin 8 is rotated to the maximum rotation angle (40 degrees), as shown in FIG. 4B, the whole is slightly oval and the isobaric lines are relatively dense. A concentric wind speed distribution packed in This is because the air passing through the vent hole 4 at the center of the retainer 2 flows as it is through the gaps between the back fins 8 along the inclination of the back fins 8, and the air passing along the side walls 9, 9 is It smoothly passes between the slopes 10A and 10A of the guide member 10 formed on each side wall 9 and the surface of each of the back fins 8A and 8A without being blocked by the guide member 10 and the back fin 8, and the retainer 2 This is thought to be based on guidance and guidance toward the center.

  Next, a schematic configuration of the register according to the second embodiment will be described with reference to FIGS. The register of the second embodiment basically has the same configuration as the register 1 according to the first embodiment, and only the formation position of the guide member 10 with respect to each back fin 8 is different. . Therefore, the following description will be made with attention paid to such differences. The same members and the like in the register 1 according to the first embodiment will be described with the same numbers.

  In FIG. 5, the pair of side walls 9, 9 forming the vent hole 4 of the retainer 2 has a flat cross section on the upstream side close to the two back fins 8 </ b> A, 8 </ b> A located on both sides of the plurality of back fins 8. The triangular guide members 10 and 10 are formed so as to protrude toward the center of the retainer 2 as viewed. Each of the guide members 10 and 10 guides the air passing through the ventilation port 4 of the retainer 2 toward the central portion of the retainer 2. That is, the air passing along the side walls 9 and 9 in the direction of the arrow A in the air vent 4 of the retainer 2 collides with the slopes 10A and 10A of the guide members 10 and 10, and the slopes 10A and 10A. Is guided in the direction of arrow B along As a result, the air passing along the side walls 9, 9 in the air vent 4 of the retainer 2 is guided toward the center of the retainer 2.

In the register 1 according to the second embodiment configured as described above, the front fin 6 is leveled and the back fin 8 is not rotated to the left or right (neutral state) and the front fin 6 is leveled. And wind speed distribution was measured in the state (back fin rotation state) which rotated back fin 8 to the maximum rotation angle (40 degree | times). The measurement results are shown in the wind speed distribution diagram of FIG.
Here, the wind speed distribution was measured based on the same conditions as those performed on the register 1 of the first embodiment.

  As shown in FIG. 6A, in the neutral state, a concentric wind speed distribution was obtained in which the whole was substantially circular and the isobaric lines were relatively densely packed. This is because the air that has passed through the vent 4 of the retainer 2 flows through the gaps between the back fins 8 and the gaps between the front fins 6 as it is, and the air that passes along the side walls 9, 9 This is considered to be based on being guided and guided toward the central portion of the retainer 2 by the inclined surfaces 10A and 10A of the triangular guide members 10 and 10 formed on the side walls 9 and 9, respectively.

  Further, in the back fin maximum rotation state in which the back fin 8 is rotated to the maximum rotation angle (40 degrees), as shown in FIG. 6B, the whole is slightly oval and the isobaric lines are relatively dense. A concentric wind speed distribution packed in This is because the air passing through the vent hole 4 at the center of the retainer 2 flows as it is through the gaps between the back fins 8 along the inclination of the back fins 8, and the air passing along the side walls 9, 9 is The guide members 10 and the rear fins 8 are guided and guided toward the central portion of the retainer 2 by the inclined surfaces 10A and 10A of the guide members 10 formed on the respective side walls 9 without being blocked by the guide members 10 and the rear fins 8. It is thought that it is based on passing smoothly between.

  Next, a schematic configuration of the register according to the third embodiment will be described with reference to FIGS. The register of the third embodiment basically has the same configuration as that of the register 1 according to the first embodiment, and the shape of the guide member 10 and the formation position of the guide member 10 with respect to each back fin 8 are the same. It is only different. Therefore, the following description will be made with attention paid to such differences. The same members and the like in the register 1 according to the first embodiment will be described with the same numbers.

  In FIG. 7, the pair of side walls 9, 9 forming the vent hole 4 of the retainer 2 has a plane cross section on the upstream side close to the two back fins 8 </ b> A, 8 </ b> A located on both sides of the plurality of back fins 8. The long trapezoidal guide members 10 and 10 are formed so as to protrude toward the center of the retainer 2. Each guide member 10, 10 is provided over the entire vertical direction of each side wall 9, 9. Each of the guide members 10 and 10 guides the air passing through the ventilation port 4 of the retainer 2 toward the central portion of the retainer 2. That is, the air passing along the side walls 9 and 9 in the direction of the arrow A in the air vent 4 of the retainer 2 collides with the slopes 10A and 10A of the guide members 10 and 10, and the slopes 10A and 10A. After getting over, they are guided and guided in the direction of arrow B along the slopes 10B and 10B (inclined toward the center of the retainer 2).

The measurement results are shown in the wind speed distribution diagram of FIG.
Here, the wind speed distribution was measured based on the same conditions as those performed on the register 1 of the first embodiment.

  As shown in FIG. 14A, in the neutral state, a concentric wind speed distribution was obtained in which the whole was substantially circular and the isobaric lines were relatively densely packed. This is because the air that has passed through the vent 4 of the retainer 2 flows through the gaps between the back fins 8 and the gaps between the front fins 6 as it is, and the air that passes along the side walls 9, 9 This is considered to be based on being guided and guided toward the central portion of the retainer 2 by the inclined surfaces 10A and 10A of the triangular first and second guide members 10C and 10D formed on the side walls 9 and 9, respectively.

The same members and the like in the register 1 according to the first embodiment will be described with the same numbers.

  In FIG. 15, the pair of side walls 9, 9 forming the vent hole 4 of the retainer 2 has a flat cross section on the upstream side close to the two back fins 8 </ b> A, 8 </ b> A located on both sides of the plurality of back fins 8. The first guide member 10 </ b> C and the second guide member 10 </ b> D that are triangular in shape are formed so as to protrude toward the center of the retainer 2. The first guide member 10C is provided on the upstream side with respect to the back fin 8A (the upper back fin 8A in FIG. 15). Further, the second guide member 10D corresponds to the rotating shaft 11 of the back fin 8A (the lower back fin 8A in FIG. 15), as in the case of the register 1 according to the first embodiment. Specifically, the axis of the rotation shaft 11 of the back fin 8A exists on the extended line L1 of the perpendicular L that is lowered from the triangular vertex 10B of the second guide member 10D toward the side wall 9. As described above, the axis of the rotation shaft 11 of the back fin 8A exists on the extended line L1 of the perpendicular L extending from the triangular apex 10B of the second guide member 10D to the side wall 9, so that the back fin 8A is Regardless of how it is rotated, the back fin 8A never interferes with the second guide member 10D. When the back fin 8A is rotated to the maximum rotation angle as shown by a two-dot chain line in FIG. 15, the surface of the back fin 8A and the inclined surface 10A of the triangular second guide member 10D are parallel to each other. become. Thus, when the back fin 8A is rotated to the maximum extent, the inclined surface 10A of the triangular second guide member 10D is parallel to the surface of the back fin 8A. Also, the air passing through the vent holes 4 of the retainer 2 along the side walls 9 of the retainer 2 is between the inclined surface 10A of the second guide member 10D formed on each side wall 9 and the surface of the back fin 8A. Can pass smoothly, and air passing through the vent 4 of the retainer 2 is not shielded. As a result, the air passing through the vent hole 4 of the retainer 2 passes smoothly along the rotational direction of the back fin 8A, and is blown out with good directivity from the bezel opening 5 of the bezel 3 to the occupant.

  Each of the first and second guide members 10 </ b> C and 10 </ b> D guides the air passing through the air vent 4 of the retainer 2 toward the center of the retainer 2.

As a result, the air passing along the side walls 9, 9 in the air vent 4 of the retainer 2 is guided toward the center of the retainer 2.

In the register 1 according to the seventh embodiment configured as described above, the front fin 6 is leveled and the back fin 8 is not rotated to the left or right (neutral state) and the front fin 6 is leveled. And wind speed distribution was measured in the state (back fin maximum rotation state) which rotated back fin 8 to the maximum rotation angle (40 degree | times). The measurement results are shown in the wind speed distribution diagram of FIG.
Here, the wind speed distribution was measured based on the same conditions as those performed on the register 1 of the first embodiment.

  As shown in FIG. 16A, in the neutral state, a concentric wind speed distribution was obtained in which the whole was substantially circular and the isobaric lines were relatively densely packed. This is because the air that has passed through the vent 4 of the retainer 2 flows through the gaps between the back fins 8 and the gaps between the front fins 6 as it is, and the air that passes along the side walls 9, 9 This is considered to be based on being guided and guided toward the central portion of the retainer 2 by the inclined surfaces 10A and 10A of the triangular first and second guide members 10C and 10D formed on the side walls 9 and 9, respectively.

  Further, in the back fin maximum rotation state in which the back fin 8 is rotated to the maximum rotation angle (40 degrees), as shown in FIG. 16B, the whole is slightly oval and the isobaric lines are relatively dense. A concentric wind speed distribution packed in This is because the air passing through the vent hole 4 at the center of the retainer 2 flows as it is through the gaps between the back fins 8 along the inclination of the back fins 8, and the air passing along the side walls 9, 9 is The first and second guide members 10C and 10D and the inclined surfaces 10A and 10A of the first and second guide members 10C and 10D formed on the side walls 9 without being blocked by the first and second guide members 10C and 10D and the back fins 8 It is considered to be based on being guided and guided toward the back and passing smoothly between the respective back fins 8A and 8A.

Here, the results of measuring the wind speed distribution in the neutral state and the deepest fin maximum rotation state of the register according to the reference example in which the guide member is not provided on each side wall 9 of the retainer 2 will be described with reference to FIGS. 17 and 18.
A register 1 according to a reference example is shown in FIG. 17, and no guide member is provided on each side wall 9 of the retainer 2.

  As shown in FIG. 18A, in the neutral state, as compared with the case of the register 1 according to the first to seventh embodiments, the whole is an ellipse and the isobaric lines are relatively sparse. The wind speed distribution was obtained. This is because air that has passed through the vent hole 4 of the retainer 2 in the direction of arrow A flows through the gaps between the back fins 8 and the gaps between the front fins 6 as it is, but no guide member is provided. This is considered to be based on the fact that the air that has passed through the respective back fins 8 is diverged to the outside of the bezel opening 5 when blown out from the bezel opening 5 of the bezel 3.

  Moreover, in the back fin maximum rotation state in which the back fin 8 is rotated to the maximum rotation angle (40 degrees), as shown in FIG. 18 (B), the whole is further deformed from the state of FIG. 18 (A). A concentric wind speed distribution with an elliptical shape and a more sparse isobar was obtained. This is because the air passing through the vent 4 at the center of the retainer 2 flows through the gaps between the back fins 8 along the inclination of the back fins 8, but the air passing along the side walls 9, 9 This is considered to be based on the fact that when the air is blown out from the bezel opening 5 of the bezel 3, it is further diverged outside the bezel opening 5 due to the absence of the guide member.

Note that the present invention is not limited to the above-described embodiments, and various improvements and side modifications can be made without departing from the scope of the present invention.
For example, in the register 1 according to each of the embodiments, the shape of the guide member 10 is formed in a triangular shape, a trapezoidal shape, or the like. However, the shape is not limited to these shapes. Any shape can be used as long as the same effect can be obtained.
In addition, the position where the guide member 10 is formed on each of the side walls 9 and 9 of the retainer 2 is not particularly limited as long as the same effect as the register according to each embodiment can be obtained. It is possible to change appropriately.
