  The present invention has been made in view of the above points, and an object of the present invention is to provide a wind direction adjusting device that can prevent a plurality of fins from being attached in an incorrect arrangement and can realize normal rotation of the fins.

According to the first aspect of the present invention, there is provided a case in which one side is an air outlet and the other side is an air inlet, the inside is an air passage, and a plurality of fin rotation shaft attachment holes are formed in opposing wall surfaces, and rotation shafts at both ends A plurality of fins having a connecting shaft portion formed together with the rotating shaft portion at one end, and a link member having a plurality of connecting holes, and the plurality of fins are connected in a set arrangement. In the wind direction adjusting device in which the shaft portion is rotatably inserted into the connection hole of the link member, the plurality of fins are different from each other in the shaft diameter of the rotation shaft portion and the shaft diameter of the connection shaft portion. The plurality of connecting holes formed in the link member are of a plurality of types having different hole diameters corresponding to the shaft diameters of the connecting shaft portions of the plurality of fins, and the connecting holes correspond to the corresponding connecting holes. It is difficult to insert a connecting shaft with a shaft diameter larger than the shaft diameter. A plurality of fins formed in the case, and the arrangement of the hole diameters of the plurality of connection holes corresponds to the arrangement of the shaft diameters of the connection shaft portions based on the setting arrangement of the fins. The rotation shaft attachment holes are of a plurality of types with different hole diameters corresponding to the shaft diameters of the rotation shaft portions of the plurality of fins, and the fin rotation shaft attachment holes are the corresponding rotation shaft portions. The rotation shaft portion having a shaft diameter larger than the shaft diameter of the rotation shaft portion has a diameter that is difficult to insert, and the arrangement of the hole diameters of the fin rotation shaft attachment holes is based on the fin setting array. When the connecting shaft portion of one fin adjacent in the setting array can be inserted into the connecting hole of the link member corresponding to the connecting shaft portion of the other fin, the one of the fins The rotation shaft portion of the fin corresponds to the rotation shaft portion of the other fin, and the case Characterized in that it is an insertion difficult shaft diameter to the fin rotating shaft Chakuana formed scan.

According to a second aspect of the present invention, in the first aspect, the rotation shaft portion of one of the fins adjacent to each other in the setting array corresponds to the rotation shaft portion of the other fin, and the fin rotation shaft is formed in the case. When it can be inserted into the hole, the connecting shaft portion of the one fin has a shaft diameter that is difficult to insert into the connecting hole of the link member corresponding to the connecting shaft portion of the other fin.

It consists of a frame that fits around the outer periphery of the front end of the case.

  In assembling the wind direction adjusting device including the constituent members, first, the plurality of vertical fins 31 are attached to the case 11. At that time, the connection shaft portions 35 of the plurality of vertical fins 31 are inserted into the vertical fin connection holes 45 of the vertical fin link members 41, and the vertical fin link members 41 are attached to the plurality of vertical fins 31. In this state, the plurality of vertical fins 31 are inserted into the case 11, and the upper and lower rotation shaft portions 33 of the plurality of vertical fins 31 are used to rotate the vertical fins of the upper wall surface 12 and the lower wall surface 13 of the case 11.

Insert into 65. Further, as a result of misalignment of the plurality of horizontal fins 51, the large-diameter connection shaft portion 55a may be inserted into the small-diameter horizontal fin connection hole 65b. Since the shaft diameter of the connecting shaft portion 55a is larger than the hole diameter of the small-diameter horizontal fin connecting hole 65b, it is difficult to insert the large-diameter connecting shaft portion 55a. I can recognize that. The operation member 67 is attached to one of the plurality of lateral fins 51 before or after the attachment of the lateral fin link member 61. FIG. 4 shows a state in which the horizontal fin link member 61 is attached to the plurality of horizontal fins 51 and the operation member 67 is attached to one of the horizontal fins 51.

  Thereafter, the rotation shaft portion 53 of the plurality of horizontal fins 51 is inserted into the horizontal fin rotation shaft receiving holes 21 and 22 formed in the left wall surface 14 and the right wall surface 15 of the case 11.

Since the plurality of horizontal fins 51 attached to the horizontal fin connecting member 61 in the correct arrangement are formed in a corresponding arrangement, the arrangement of the shaft diameters of the rotating shaft portion 53 and the horizontal fin rotation of the case 11 are the same. The arrangement of the hole diameters of the dynamic shaft attachment holes 21 and 22 is in a correctly corresponding state, and the plurality of horizontal fins 51 are arranged in the correct arrangement and smoothly into the horizontal fin rotation shaft attachment holes 21 and 22 of the case 11. Can be pivoted. Further, when the plurality of horizontal fins 51 are attached to the case 11, the operation locking portions 32 of the vertical fins 31 a are held by the holding pieces 70 formed on the back surface of the operation member 67. FIG. 5 is a perspective view showing a state in which the plurality of horizontal fins 51 are attached to the case 11. Thereafter, when the front frame 71 is attached to the front surface of the case 11, the wind direction adjusting device 10 of FIG. 1 is obtained.

  In this embodiment, when the connecting shaft portions 55 of the plurality of horizontal fins 51 are inserted into the horizontal fin connection holes 65 of the horizontal fin link member 61, the horizontal fins 51 and 51 that are adjacent to each other in a set arrangement are used. When one of the horizontal fins having the small-diameter connecting shaft portion 55b is misaligned, the horizontal fin link member 61 corresponding to the large-diameter connecting shaft portion 55a formed on the other horizontal fin has a large-diameter horizontal width. A small-diameter connecting shaft portion 55b can be inserted into the fin connecting hole 65a. However, in that case, the large-diameter rotation shaft portion 53a formed in the horizontal fin having the small-diameter connecting shaft portion 55b is replaced with the small-diameter horizontal fin rotation shaft hole formed in the case 11. 21b and 22b, the lateral fins having the small-diameter connecting shaft portions 55b cannot be attached to the case 11, and the lateral fins 51 can be prevented from being attached to the case 11 due to misalignment.

  Further, in the present embodiment, in the horizontal fins 51 and 51 that are adjacent to each other in the setting arrangement, one horizontal fin having the small-diameter rotation shaft portion 53b is a large-diameter rotation formed on the other horizontal fin. A small-diameter rotation shaft portion 53b can be inserted into large-diameter horizontal fin rotation shaft attachment holes 21a and 22a formed in the case 11 corresponding to the moving shaft portion 53a. However, in that case, when the connecting shaft portion 55 of the horizontal fin 51 is inserted into the horizontal fin connecting hole 65 of the horizontal fin link member 61 in advance, the large fin formed on the horizontal fin having the small-diameter rotating shaft portion 53b. The connecting shaft portion 55a having a diameter must be inserted into the small-diameter horizontal fin connecting hole 65b formed in the horizontal fin link member 61, which makes it difficult to insert. The small-diameter rotation shaft portion 53b of the horizontal fin 51 is inserted into the large-diameter horizontal fin rotation shaft receiving holes 21a and 22a formed in the case 11, and the horizontal fins are attached in a misalignment. Can be prevented.

  In the above-described embodiment, the configuration of the present invention that prevents misalignment is applied only to the horizontal fins. However, the configuration for preventing misalignment is applied to the vertical fins as well as the horizontal fins, or misalignment prevention is applied only to the vertical fins. A configuration may be applied. Further, the types of diameters of the rotation shaft portion, the connection shaft portion, the fin rotation shaft attachment hole, and the fin connection hole are not limited to two types of large and small, and may be three types of large, medium, and small and more.

  As described above, according to the present invention, when the plurality of fins are attached to the fin connecting member, it is possible to prevent an incorrect arrangement of the fins, and it is possible to obtain a wind direction adjusting device having a normal attachment state in which the fins rotate smoothly. In addition, even if a plurality of fins can be forcibly attached to the fin connecting member in a misaligned state, it is difficult to attach the fins to the case in that case.
