Description

  The present invention relates to a register for adjusting air blowing used for ventilation in an automobile or the like and an air outlet for air conditioning.

  Conventionally, a laterally movable louver in which a plurality of lateral fins are arranged in parallel and a longitudinally movable louver in which a plurality of longitudinal fins are arranged in parallel are arranged in the bezel forming the ventilation path so as to be positioned in the front-rear direction. An air blowing adjustment register is known (Patent Documents 1 and 2).

Each horizontal fin and each vertical fin has a structure in which a link bar is connected to each fin so as to face the same direction when the louver is rotated.
As shown in FIG. 11, the air blow adjustment register of Patent Document 1 is fitted with the operation knob 100 slidably in the axial direction (lateral direction) on the lateral fin 110 at the center of the lateral movable louver. In addition, it is provided so as to be able to rotate up and down together with the lateral fins 110 of the laterally movable louver. FIG. 11 is a cross-sectional view of the register described in Patent Document 1. In FIG. An engagement portion that engages with an engaged portion of the vertical fin 104 of the longitudinally movable louver located at the rear is formed at the tip of the operation knob 100. When adjusting the direction of the wind to the left and right, the air blow adjustment register described above slides the operation knob 100 to the left or right on the lateral fin 110 of the laterally movable louver so as to change the direction of the subsequent longitudinally movable louver. To change the direction of the wind up and down, change the direction of the wind by rotating the operation knob up or down together with the fins of the laterally movable louver.

  In Patent Document 1, as shown in FIG. 11, a bifurcated operating piece 102 protrudes from the operation knob 100 as the engaging portion, and the vertical fin of the central vertical movable louver in which the operating piece 102 is located rearward. It is adapted to engage with a displacement shaft 106 (a shaft positioned on the front side of the rotational axis O of the vertical fin 104) provided in 104. Then, according to the left / right movement of the operation knob 100, the operating piece engages with the displacement shaft 106 provided as the engaged portion on the vertical fin 104 from either the left or right side, and the vertical fin 104. I am trying to change the direction.

  In Patent Document 2, a rack is extended laterally as the engaging portion behind the operation knob, and the rack serves as an engaged portion provided in a central vertical movable louver located at the rear. It arrange | positions so that it may mesh with a partial gearwheel. When the operation knob is moved in either the left or right direction, the direction of the vertical fin is changed via a partial gear engaged with the rack. The partial gear is a spur partial gear.

  By the way, conventionally, the air blow adjustment registers of Patent Documents 1 and 2 described above have the rotational axes of the vertical fins and the horizontal fins at the blowout port whose corners are quadrangular, such as a rectangular shape or a square shape. Are arranged in a grid so as to be orthogonal to each other. Accordingly, the two sides located on the top and bottom of the quadrangle and the horizontal fin can be arranged in parallel, and the two sides located on the left and right and the vertical fin can be arranged in parallel, so that it can be arranged with good appearance.

Japanese Patent Laid-Open No. 2000-318440 FIG. Japanese Patent Laid-Open No. 2007-131055 FIG.

  However, conventionally, as shown in FIG. 10, even when the cross-sectional shape of the air outlet 120 is a parallelogram, the rotational axes of the vertical fins 104 and the horizontal fins 110 are arranged so as to be orthogonal to each other. It was. For this reason, conventionally, when the vertical fins are arranged in parallel to the left and right sides of the air outlet, the horizontal fins are not parallel to the upper and lower sides, and the horizontal fins are in parallel to the upper and lower sides of the air outlet. If they are arranged in parallel, the vertical fins are not parallel to the left and right sides, and the appearance is poor.

  Further, it is conceivable to use the configuration of the engaging portion and the engaged portion of Patent Document 1 in a register having a parallelogram-shaped blower outlet in cross section. That is, the vertical fins 104 shown in FIG. 11 are arranged in parallel to the left and right sides of the air outlet, and the horizontal fins 110 are arranged in parallel to the upper and lower sides of the air outlet, so that the respective rotation axes are oblique to each other. It is conceivable to arrange them as follows.

  Here, FIG. 12A shows a case where the outlet is located at the neutral position of the vertical fin 104 (position where the air flow blown out from the outlet through the fin goes straight) when the register is viewed from the passenger compartment side. The positional relationship between the displacement shaft 106 and the operating piece 102 is shown. In the figure, the upper limit position of the operating piece 102 is indicated by A1, and the lower limit position is indicated by B1. In Patent Document 1, the upper limit position and the lower limit position of the operating piece 102 are engaged with the upper and lower ends of the notches of the vertical fin 104 located near the upper end and the lower end of the displacement shaft 106 at the position of the operating piece 102. It is prescribed by When the operating piece 102 is positioned at the upper limit position, the lateral fin 110 is in the downward limit position, and when the operating piece 102 is positioned in the lower limit position, the lateral fin 110 is in the upward limit position.

  FIG. 12B shows that when the register is viewed from the passenger compartment of the air outlet, the eccentric shaft 106 is moved from the neutral position of the vertical fin 104 so that the vertical fin 104 faces leftward. The positional relationship between the displacement shaft 106 and the operating piece 102 is shown. As shown in FIG. 12B, in this case, the upper limit position of the working piece 102 is lowered from A1 to A2, and the lower limit position of the working piece 102 is lowered from B1 to B2. Here, when the operating piece 102 is positioned at the upper limit position A1 and the lower limit position B1, if the horizontal fin 110 is set to the maximum downward position and the maximum upward position, the upper limit position of A2 is the maximum downward of the horizontal fin 110. It is no longer a position.

  When the displacement shaft 106 is moved by rotating the vertical fin 104 so as to face rightward, the lower limit position of the operating piece 102 moves upward from B1 for the same reason as described above. The lower limit position of the actuating piece 102 located at is not the maximum upward position of the lateral fin 110. As described above, the configuration of the engaging portion and the engaged portion of Patent Document 1 has a problem that it cannot be used in a register in which horizontal fins and vertical fins are obliquely crossed.

  In Patent Document 2, the rack that is the engaging portion and the partial gear that is the engaged portion are configured to mesh with each other. However, when the vertical fins and the horizontal fins are arranged obliquely, There is a problem that the rack and the partial gear are not smoothly engaged.

  It is an object of the present invention to operate an operation knob provided on one of the fins in a register in which a plurality of horizontal fins and a plurality of vertical fins are arranged obliquely to each other. It is an object to provide an air blowing adjustment register capable of easily changing the direction of each by rotating a fin and a vertical fin.

In order to solve the above problems, the invention of claim 1 is characterized in that a first movable louver including a plurality of first fins arranged in parallel with each other in a ventilation path and rotatably connected to each other; A plurality of second louvers that are arranged in parallel with each other and rotatably connected to each other so as to be oblique to the rotational axis of the first fin of the first movable louver on the downstream side of the ventilation path with respect to the one movable louver.

A gear, wherein the rotation of the second fin When the operation knob slides along the axis, the first fin is rotated by meshing with the rack, and the rack is allowed to rotate in the same direction when rotating around the rotation axis of the second fin. And the three- dimensional gear is parallel to a plane including the rotation axis of the second fin and rotated about the rotation axis of the second fin when rotated around the rotation axis of the first fin. An air blowing adjustment register having a plurality of tooth tips included in a line segment orthogonal to the center, wherein the plurality of tooth tips are arranged at equal intervals around the rotation axis of the first fin. It is said.

  According to a second aspect of the present invention, in the first aspect, an opening cross section of the air outlet of the ventilation path is formed in a parallelogram, and one of the first fin and the second fin is a parallelogram. It is arranged parallel to two upper and lower sides, and the fin between the other is arranged parallel to two right and left sides of the parallelogram.
