  The plate-like portion of the wind direction plate projects to the back side from the main body, and a guide pin is provided at a rear rear side position from the support shaft portion, while the inner peripheral portion of the frame member corresponds to the guide pin. The guide pin is inserted and guided when the wind direction plate is rotated, and a guide portion for restricting the rotation range of the wind direction plate is provided. When the wind direction plate is in the ventilation position, the plate portion covers the guide portion (claim 3). The guide pin of the wind direction plate and the guide portion of the inner peripheral portion corresponding thereto can be covered with the plate-like portion to improve the appearance.

  An embodiment to which the present invention is applied will be described with reference to FIGS. FIG. 1 is a front view of a blow grill according to the present invention, FIG. 2 is a cross-sectional view taken along line II-II in FIG. 1, and FIG. 3 is a perspective view of the blow grill as viewed from an oblique direction. The blow-out grill 1 has a two-layer structure including an outer frame member 2 and an inner frame member 3. The outer frame member 2 includes a rectangular frame front surface portion 21 that surrounds an opening 20 that is elongated in the left-right direction, and a rectangular tube-shaped frame rear portion 22 that is bent from the inner peripheral edge of the frame front surface portion 21 and protrudes backward. It is integrally molded.

  The inner frame member 3 is formed in a rectangular tube shape that is slightly smaller than the outer frame member 2, and constitutes an air-conditioning air outlet 30 inside. The inner frame member 3 is inserted into the outer frame member 2, and the projecting support shaft portions 31, 31 provided at substantially the center of the left and right ends of the inner frame member 3 are connected to the frame rear portion 22 of the outer frame member 2. The inner frame member 3 is pivoted slightly upward and downward with respect to the outer frame member 2 so that the direction of the outlet 30 is up and down. Can be adjusted.

  Inside the air outlet 30 of the inner frame member 3, a plurality of wind direction plates 4 that adjust the air-conditioning air blowing direction are rotatably provided at predetermined intervals in the left-right direction. The wind direction plate 4 is bent from the vertical plate-shaped main body 40, the upper plate-shaped portion 41 that is bent from the upper edge of the main body 40 and protrudes toward the back side of the main body 40, and the lower edge of the main body 40. The lower plate-like portion 42 protruding to the back side is formed in a substantially U-shaped cross section.

  The upper and lower plate-like portions 41 and 42 have substantially the same shape, and the lower plate-like portion 42 will be mainly described. The lower plate-like portion 42 is formed in a substantially mountain shape having a round shape that protrudes toward the back side of the main body 40 over almost the entire length in the front-rear direction of the lower edge of the main body 40 with the blowing direction of the air-conditioning air as the front side. In order to enlarge the area as much as possible, the plate-like portion 42 has a front edge extending in an inclined curved shape from the front end of the lower edge of the main body 40 to the back side of the main body 40 and slightly obliquely backward, and a gentle arc shape continuously from the front edge. And a straight rear edge orthogonal to the rear end of the lower edge of the main body 40, and a shape biased toward the rear end side.

  The lower plate-like portion 42 is provided with a cylindrical projection-shaped support shaft portion 43 that protrudes downward at a position farther to the back side than the main body 40 and at an intermediate position near the front edge. The upper plate-like portion 42 is provided with a support shaft portion 43 that protrudes upward coaxially with the support shaft portion 43 of the lower plate-like portion 42.

  The wind direction plate 4 is inserted into the circular concave bearing portions provided on the inner peripheral upper portion 32 and the inner peripheral lower portion 33 of the inner frame member 3, and the upper and lower support shaft portions 43, 43 are rotated inside the inner frame member 3. It is assembled freely. The wind direction plate 4 has a ventilation position (solid line in FIG. 2) for guiding air-conditioning air from between the wind direction plates 4 around the axis of the upper and lower support shafts 43, 43 (CL-CL line in FIG. 1) as the rotation center. All the wind direction plates 4 are arranged so as to be substantially flush with each other so as to cover the outlet 30 and can be displaced to a closed position (virtual line in FIG. 2) where the air-conditioning air is shut off.

  The wind direction plate 4 protrudes downward from the lower plate-like portion 42 to a position farther to the rear side than the main body 40 and closer to the rear edge than the support shaft portion 43. Guide pins 44 are provided.

  Corresponding to the guide pins 44 of the wind direction plate 4, the inner peripheral lower portion 33 of the inner frame member 3 is formed with a lower half portion 33 b lower than the front half portion 33 a and moves as the wind direction plate 4 rotates. The guide pin 44 is avoided. Further, a groove-shaped guide portion 35 that communicates with the front half portion 33a of the inner frame member 3 from the rear half portion 33b side and guides the movement while inserting the guide pin 44 is forward of the inner frame member 3. It extends in an arc shape.

  The guide portion 35 is closed at the front end, and when the wind direction plate 4 is rotated to the closed position, the guide pin 44 abuts on the front end and serves as a stopper for restricting further rotation of the wind direction plate 4. Eggplant.

  Thus, the upper and lower plate-like portions 41 and 42 of the wind direction plate 4 assembled to the inside of the inner frame member 3 (inside the blowout port 30) protrude most from the main body 40 when the wind direction plate 4 is in the ventilation position. The intermediate edge is formed so as to be close to and opposed to the adjacent wind direction plate 4 so as to cover the inner peripheral upper portion 31 and the inner peripheral lower portion 32 of the inner frame member 3 between the two wind direction plates 4. It is. In this case, since the plate-like portions 41 and 42 are formed in a mountain shape in which the rear edge is formed in a straight line perpendicular to the main body 40 and biased rearward, the lower half of the plate-like portion 42 on the lower side is the inner peripheral lower portion. 33 guide portions 35 are covered. Further, since the plate-like portions 41 and 42 are formed in an inclined curved shape from the front edge to the intermediate edge, they do not interfere with the adjacent wind direction plate 4 by the rotation between the ventilation position and the closed position.

  In addition, all the wind direction plates 4 are connected to the connecting member 6 in which the tip pins 46 of the protrusions 45 projecting obliquely rearward from the upper and lower intermediate positions on the back surface of the main body 40 shown in FIG. By rotating the central wind direction plate 4 provided with the other wind direction plates 4 according to this, the other wind direction plates 4 are also rotated integrally.

  According to the present embodiment, plate-like portions 41 and 42 projecting from the upper and lower edges of the main body 40 to the back side are formed on the wind direction plate 4, and the plate-like portions 41 and 42 are vertically moved at the intermediate positions of the plate-like portions 41 and 42. Since the support shaft portions 43 and 43 are provided, the inner peripheral upper portion 32 and the inner peripheral lower portion 33 of the inner frame member 3 are covered and covered by the upper and lower plate-like portions 41 and 42 between the wind direction plates 4 at the ventilation position. The shaft portions 43 and 43 and the attachment portions to the inner frame member 3 are not exposed so that the appearance is good. In addition, the upper and lower plate-like portions 41 and 42 are larger than the upper and lower tongue-like protrusions of the conventional structure and have a correspondingly higher strength, so that it is not necessary to provide reinforcing ribs.

  Further, since the guide pin 44 is provided at the intermediate position of the lower plate-like portion 42, the guide pin 44 is not exposed and provided at the lower portion of the inner periphery of the inner frame member 3 corresponding to the guide pin 44. The groove-shaped guide portion 35 can be covered with the plate-like member 42, and the appearance is not impaired.

  Further, since the guide pin 44 is provided on the plate-like portion 42, there is a degree of freedom in the formation position of the guide pin 44, and the guide pin 44 is positioned closer to the rear edge of the plate-like portion 42 and than the main body 40. By forming the guide portion 35 as far as possible to the back side as much as possible, the corresponding guide portion 35 becomes a deepened position on the rear side of the inner peripheral lower portion 33, so that the guide portion 35 can be easily hidden by the plate-like portion 42.

  In addition, the above-mentioned embodiment is an illustration and does not limit the scope of the present invention, and the present invention includes various modifications and changes to the above-described embodiment. For example, in the above-described embodiment, the guide pin 44 is provided on the lower plate-like portion 42 and the guide portion 35 is provided on the inner peripheral lower portion 33 of the inner frame member 3. The guide portion may be provided on the inner periphery of the inner frame member. Further, the upper and lower plate-like portions 41 and 42 of the wind direction plate 4 are not limited to the rounded mountain shape biased rearward, but may be a semi-circular shape or a rounded trapezoidal shape with the leading edge being inclined although the area is slightly reduced.
