And a rotation mechanism that changes the air blowing direction by synchronously rotating the plurality of rear blades, and the predetermined one of the plurality of rear blades includes the first axial direction. The engaging column intersecting with each other, and the rotating mechanism includes an operation knob attached to one of the plurality of front blades so as to be slidable in the first axial direction, and the rear portion of the operation knob. It is pivotally connected around a third axis parallel to the first axis, A link arm that engages with the engagement column, and all the front blades are rotated around the first axis by the rotation of the operation knob, while the operation knob is moved in the first axis direction. The following solution was taken for a register in which all the rear blades are rotated around the second axis through the link arm by the sliding movement.

According to a first aspect of the present invention, the rear blade provided with the engagement column is further provided with an overhang portion protruding from a side surface, and the engagement column is connected to the overhang portion, and the first shaft direction and straight interlinked, and intersects the rear blade, the link arm is characterized in that it constantly engaged with the engagement pillars.

One of the rear blades is provided with an engagement column that engages with the link arm, and the engagement column is substantially orthogonal to the first axial direction. Therefore, when the link arm is slid in the first axis direction, the angle formed between the moving direction of the link arm and the extending direction of the engagement column does not always change, and the link arm can be smoothly slid. In addition, since the link arm is always engaged with the engaging column, when the operation knob is rotated around the first axis, the link arm rotates around the third axis parallel to the first axis. The link arm does not come off the engaging column. Therefore, the direction of both the front and rear blades can be changed. In this way, even if the front and rear blades cross each other, a register capable of adjusting the air blowing direction can be realized with a simple structure of a link arm and an engagement column. And since it is such a simple structure, manufacture of a register becomes easy. Moreover, since the link arm is always engaged with the engaging column as described above, it is possible to prevent the operation knob from rattling.

In addition , since the projecting portion is provided on the blade after the engagement column is provided and the engagement column is connected to the projecting portion, the intersection angle between the engagement column and the rear blade is relatively large. Can be provided. Therefore, when the crossing angle between the front and rear blades is relatively larger than the right angle, the engagement column can be provided so as to be substantially orthogonal to the front blade.

According to the second invention, has realized the engagement between the engaging posts and link arm spheres provided engaging post, it is possible to adjust the wind direction with a relatively simple structure.

According to the third aspect of the present invention, since the notch portion that opens forward is provided between the protruding portions of the blade after the engagement column is provided, the link arm and the rear end of the link arm enter the notch portion. Interference with the blade can be avoided. Accordingly, both the front and rear blades can be brought close to each other, and the change of the wind direction by the rotation of the rear blade can be executed efficiently, and the register can be made compact.

  Next, a method for adjusting the blowing direction of conditioned air in the vertical and horizontal directions will be described. First, the case where the blowing direction of conditioned air is adjusted up and down will be described with reference to FIG.

  In order to adjust the blowing direction of the conditioned air downward when the front blade 7 is in the horizontal state (the state shown in FIG. 7A), the operation knob 11 is rotated downward. As a result, the front blade 7 to which the operation knob 11 is mounted is rotated around the left and right axis A so that the front portion of the front blade 7 is on the lower side and the rear portion is on the upper side. Similarly, all of the front blades 7, 7,... Rotate so that the front portion is on the lower side and the rear portion is on the upper side. At this time, the connecting portion JT (the connecting piece 11b and the connecting protrusion 13e) between the link arm 13 and the operation knob 11 moves obliquely forward and upward from the position shown in FIG. Move forward while rotating around. Thus, the conditioned air blowing direction shown in FIG. 7B is adjusted downward.

  Further, in order to adjust the blowing direction of the conditioned air upward from the time when the front blade 7 is in the horizontal state (the state shown in FIG. 7A), the operation knob 11 is rotated upward in the opposite direction. As a result, the front blade 7 on which the operation knob 11 is mounted rotates around the left and right axis A so that the front portion of the front blade 7 is on the upper side and the rear portion is on the lower side. Similarly, all the other front blades 7, 7,... Rotate so that the front part is on the upper side and the rear part is on the lower side. At this time, since the connecting portion JT between the link arm 13 and the operation knob 11 moves obliquely forward and downward from the position shown in FIG. 7A, the link arm 13 moves forward while rotating around the connecting axis C. Moving. Thus, the conditioned air blowing direction shown in FIG. 7C is adjusted upward.

  On the other hand, when adjusting the blowing direction of the conditioned air to the left and right, the operation knob 11 is slid in the left and right direction. At this time, since the engaging column 9f extends so as to be orthogonal to the sliding movement direction (that is, the first axis direction) of the operation knob 11 (see FIG. 3), while the operation knob 11 is slid, The angle formed with the engaging column 9f does not always change. Thereby, the operation knob 11 can be smoothly slid in the first axial direction without being obstructed by the engaging column 9f. Then, the moving force of the operation knob 11 is transmitted from the engagement pieces 13a, 13a of the link arm 13 to the rear blade 9 after the engagement pillar 9f is provided, and the rear blade 9 is rotated around the vertical axis B (left and right). The other rear blades 9 are rotated in the left-right direction in conjunction with the rotation, and the conditioned air blowing direction is adjusted to the left and right.

  Furthermore, in the register 1 of the present embodiment, the notch portion 9d that opens forward is provided between the overhangs 9e, 9e of the blade 9 after the engagement column 9f is provided, so that the end of the link arm 13 is the notch portion. By entering into 9e, interference between the link arm 13 and the rear blade 9 can be avoided. Therefore, both the front and rear blades 7 and 9 can be brought close to each other, the change of the wind direction by the rotation of the rear blades 9, 9,... Can be performed efficiently, and the register 1 can be made compact.

  In addition, in the said embodiment, although the blower outlet 3a is a parallelogram, it is not limited to this, For example, trapezoid shape may be sufficient.

In the above embodiment, the pair of substantially rectangular plate-like projecting portions 9e, 9e project to the right side of the rear blade 9, but may project to the left side, or one of them projects to the right side of the rear blade 9. The overhang and the other may overhang the left side of the rear blade 9. Further, the pair of projecting portions 9e, 9e may project on both the left and right sides of the rear blade 9.

  Moreover, in the said embodiment, although one overhang | projection part 9e is provided, it is not limited to this, Only one may be sufficient.
