Hereinafter, the present embodiment will be described in detail with reference to the drawings.
1 to 8 are for explaining this embodiment.

  <Configuration> The configuration of this embodiment will be described below.

  In a vehicle such as an automobile, an air outlet for blowing air from the air conditioner is provided in the passenger compartment. A wind direction adjusting device 1 as shown in FIG. 1 is provided at the air outlet.

  The wind direction adjusting device 1 is provided with louvers 4 to 6 capable of adjusting the air direction of air inside an outlet member 3 that blows out air. The louvers 4 to 6 pivotally support a rotating shaft 7 provided at an end portion thereof with respect to a shaft hole portion 11 provided in the air outlet member 3.

  Here, the wind direction adjusting device 1 can be, for example, a ventilator grill provided on the instrument panel. The wind direction adjusting device 1 is for adjusting the air wind direction in the vertical direction 15 and the horizontal direction 16. In this embodiment, the air wind direction is adjusted in the vertical direction 15, but may be adjusted in the horizontal direction 16.

  The air outlet member 3 is a cylindrical frame-shaped member made of hard resin. The blower outlet member 3 has a rectangular shape or a circular shape (or a spherical shape).

  The louvers 4 to 6 are blade-shaped members made of hard resin. The rotation shaft 7 is provided so as to be positioned on the same axis line at both ends of the louvers 4 to 6 in the longitudinal direction (in this case, the left-right direction 16).

  The shaft hole portion 11 can be directly provided at a position (side portion or the like) corresponding to the rotation shaft 7 of the outlet member 3. Further, the shaft hole portion 11 can be provided in a bearing member 12 (see FIG. 3) that is separate from the air outlet member 3. The bearing member 12 is installed in a mounting seat provided at a position corresponding to both ends of the louvers 4 to 6 in the outlet member 3. As described above, the shaft hole portion 11 provided in the air outlet member 3 is indirectly provided in the shaft hole portion 11 provided directly in the air outlet member 3 and the air outlet member 3 (via the bearing member 12 or the like). The shaft hole portion 11 is included.

  In this embodiment, the operating force of the louvers 4 to 6 can be generated without using the frictional force between the rotating shaft 7 and the shaft hole portion 11. Therefore, the radial dimension management between the rotating shaft 7 and the shaft hole portion 11 does not need to be severe. Further, the operation force of the louvers 4 to 6 can be generated without using the frictional force between the inner surface of the outlet member 3 (or the bearing member 12) and the end portions of the louvers 4 to 6. Therefore, dimensional management between the width dimension of the inner surface of the outlet member 3 and the length of the louvers 4 to 6 does not have to be severe.

  In contrast to the basic configuration as described above, this embodiment has the following configuration.

  (1) The sliding resistance generating member 21 capable of generating sliding resistance by pressing the end of the rotating shaft 7 in the axial direction (in this case, the left-right direction 16) at the back of the shaft hole portion 11 is provided. Provide.

  Here, the sliding resistance generating member 21 can be configured by a member different from the air outlet member 3 and the louvers 4 to 6. For the sliding resistance generating member 21, it is preferable to use a flexible material capable of generating a large sliding resistance such as silicone rubber or elastomer. The sliding resistance generating member 21 can be accommodated and installed inside the accommodating portion 25 provided in the air outlet member 3. The accommodating part 25 can define a space (sliding resistance generating member accommodating space) surrounding the outer end of the shaft hole part 11.

(2) A plurality of louvers 4 to 6 are arranged in parallel on the outlet member 3.
Further, the plurality of louvers 4 to 6 are connected by a link member 31 so as to be integrally rotatable.
The link member 31 may be a biasing member 32 that can bias the end of the rotating shaft 7 toward the sliding resistance generating member 21 in the axial direction.

  Here, the plurality of louvers 4 to 6 are arranged in parallel with each other along the surface of the outlet opening of the outlet member 3. Three or more louvers 4 to 6 are preferably provided. The link member 31 connects the connecting shafts 34 to 36 provided in the louvers 4 to 6. The connection shafts 34 to 36 extend in a direction parallel to the rotation shaft 7. The link member 31 includes connecting shaft holes 37 to 39 that can support the connecting shafts 34 to 36.

  At this time, the operation force of the louvers 4 to 6 can be generated without using the frictional force between the connecting shafts 34 to 36 and the connecting shaft holes 37 to 39. Accordingly, the dimensional management between the connecting shafts 34 to 36 and the connecting shaft holes 37 to 39 does not have to be severe.

  (3) The biasing member 32 may be a leaf spring 41.

  Here, the leaf spring 41 is made of metal or resin. The leaf spring 41 has a surface perpendicular to the connecting shaft holes 37 to 39 and extends in the direction in which the louvers 4 to 6 are arranged.

  (4) The sliding resistance generating member 21 may be provided with respect to the rotating shaft 7a of the louver 5 located in the middle of the juxtaposed direction.

  Here, the louver 5 located in the middle is obtained by removing the louvers 4 and 6 located on both sides (up and down in the drawing) in the juxtaposed direction. When there are three or more louvers 4 to 6, the louver 5 is preferably located at the center in the juxtaposed direction.

  The louver 5 located in the middle of the juxtaposed direction can be provided with an operation portion 26 (see FIG. 1) for manual operation. The operation unit 26 adjusts the direction of the louvers 4 to 6 and adjusts the direction of another louver installed behind the louvers 4 to 6.

  (5) Between the louvers 4 and 6 located on both sides in the juxtaposed direction and the louver 5 located in the middle of the juxtaposed direction, the louver 5 located in the middle of the juxtaposed direction is moved to the sliding resistance generating member 21. An urging member 32 in which an elastic force is accumulated may be interposed so as to be urged in the axial direction.

  Here, when the urging member 32 is a leaf spring 41, for example, the connecting shafts 34 and 36 of the louvers 4 and 6 located on both sides in the juxtaposed direction and the connecting shaft of the louver 5 located in the middle of the juxtaposed direction. 35 is installed with the axial position shifted.

  At this time, the connecting shafts 34 and 36 of the louvers 4 and 6 located on both sides in the juxtaposed direction are close to the sliding resistance generating member 21 (or located near the ends of the louvers 4 and 6). The connecting shaft 35 of the louver 5 located in the middle of the direction is arranged so as to be far from the sliding resistance generating member 21 (or located closer to the center of the louver 5).

  Next, the leaf spring 41 is moved in the axial direction with respect to the connecting shafts 34 and 36 of the louvers 4 and 6 located on both sides in the juxtaposed direction and the connecting shaft 35 of the louver 5 located in the middle of the juxtaposed direction. It is supported so that it does not move. For this purpose, for example, the connecting shafts 34 and 36 and the connecting shaft 35 are provided in opposite directions, or stoppers are provided at the ends of the connecting shafts 34 to 36.

  In this case, the connecting shafts 34 and 36 of the louvers 4 and 6 located on both sides in the juxtaposed direction are directed toward the end portions of the louvers 4 and 6, and the connecting shaft 35 of the louver 5 located in the middle of the juxtaposed direction is provided. The louver 5 is directed toward the center. For this purpose, a notch 5a (see FIG. 4) or a hole may be provided at the end of the louver 5 located in the middle of the juxtaposed direction, and the connecting shaft 35 may be provided in the notch 5a.

  And, between the connecting shafts 34 and 36 of the louvers 4 and 6 located on both sides in the juxtaposed direction and the connecting shaft 35 of the louver 5 located in the middle of the juxtaposed direction, a linear leaf spring 41 is interposed. The part is interposed in a state where it is bent in a direction away from the sliding resistance generating member 21.

  As described above, the connecting shafts 34 and 36 of the louvers 4 and 6 located on both sides in the juxtaposed direction are urged to the side opposite to the sliding resistance generating member 21 by the elastic force that the leaf spring 41 is to return. The connecting shaft 35 of the louver 5 located in the middle of the juxtaposed direction is biased toward the sliding resistance generating member 21 side.

  When there are three or more louvers 4 to 6, it is preferable that the connecting shafts provided on the other louvers are not affected by the urging force in the axial direction by the urging member 32. For example, a gap is provided between the connecting shaft and the connecting shaft hole of the link member 31 so that the connecting shaft can move in the axial direction as long as the connecting shaft does not come out of the connecting shaft hole of the link member 31.

(6) The resistance increasing portion 51 may be provided at the end of the rotating shaft 7 a of the louver 5.
The sliding resistance generating member 21 may be provided with a receiving portion 52 that receives the resistance increasing portion 51.

  Here, the resistance increasing portion 51 may be anything as long as it can increase the sliding resistance with the sliding resistance generating member 21. The resistance increasing portion 51 can be, for example, a diameter-enlarged portion that is integrally provided at the end of the rotating shaft 7a and has a larger diameter than the rotating shaft 7a. For example, as shown in FIG. 2, the receiving portion 52 has a mortar-shaped concave portion 55 that is recessed outward in the axial direction, and the outer peripheral portion of the resistance increasing portion 51 is an inclined surface of the mortar-shaped concave portion 55. You may make it receive.

  Further, for example, as shown in FIG. 5, the receiving portion 52 may be a flat surface and the end surface of the resistance increasing portion 51 may be received by the entire surface.

  In order to allow the rotation shaft 7a having the resistance increasing portion 51 to be mounted in the shaft hole portion 11, the shaft hole portion 11 is provided with a slit portion 11a for allowing the rotation shaft 7a to pass from the side. Also good.

  <Operation> The operation of this embodiment will be described below.

  When the air conditioner is operated in the passenger compartment, air from the air conditioner is blown out from the air outlet. And a passenger | crew can adjust a wind direction with the wind direction adjustment apparatus 1 provided in this air blower outlet.

  The wind direction adjusting device 1 adjusts the wind direction by changing the direction of the louvers 4 to 6. When the direction of the louvers 4 to 6 is changed, an operating force is applied to the louvers 4 to 6. By stabilizing the operation force applied to the louvers 4 to 6, the wind direction adjusting device 1 can have a good feeling of operation.

  <Effect> According to this embodiment, the following effects can be obtained.

  (Effect 1) The sliding resistance generating member 21 is provided in the inner part of the shaft hole portion 11 of the outlet member 3. The sliding resistance generating member 21 and the end of the rotating shaft 7 of the louvers 4 to 6 are pressed against each other in the axial direction to generate sliding resistance with respect to the rotation of the louvers 4 to 6. Thereby, the operating force of the louvers 4 to 6 can be obtained using the sliding resistance generated by the axial pressure contact between the sliding resistance generating member 21 and the end of the rotating shaft 7.

  Therefore, for example, as in the case of FIGS. 7 and 8 in which the sliding resistance generating member 21 is not provided, for example, the friction between the rotating shaft 7 of the louvers 4 to 6 and the shaft hole portion 11 of the outlet member 3. The louvers 4 to 4 are caused by the force, the frictional force between the inner surface of the outlet member 3 and the ends of the louvers 4 to 6, the frictional force between the connecting shafts 34 to 36 and the connecting shaft holes 37 to 39. Compared with the one in which the operation force of 6 is obtained, the operation force can be set easily and reliably.

  Therefore, strict dimensional control (on the level of 0.1 mm) between the rotating shaft 7 and the shaft hole portion 11 and (0) between the inner surface of the outlet member 3 and the end portions of the louvers 4 to 6. It is possible to eliminate the need for strict dimensional management (on the order of 0.1 mm) and strict dimensional management (on the 0.1 mm level) between the connecting shafts 34 to 36 and the connecting shaft holes 37 to 39. . Moreover, the limit of the setting of the operating force when performing using the frictional force between the blower outlet member 3 and the louvers 4-6 can be eliminated.

  That is, by using the sliding resistance generating member 21 made of a separate member from the outlet member 3 and the louvers 4 to 6, the degree of freedom is increased, so that the generated sliding resistance can be set finer and more delicate. Therefore, the louvers 4 to 6 having the operation force as designed can be manufactured easily and with good reproducibility. Therefore, the operation force of the louvers 4 to 6 can be easily made constant. Alternatively, the louvers 4 to 6 having a constant operating force can be easily and reliably produced. In addition, a comfortable operating force can be achieved.

  Furthermore, by providing the sliding resistance generating member 21 at the back of the shaft hole portion 11, the sliding resistance generating member 21 can be installed at a position that cannot be seen from the outside.

  (Effect 2) A plurality of louvers 4 to 6 are connected by a link member 31 so as to be integrally rotatable. At this time, the linking member 31 that connects the plurality of louvers 4 to 6 may be the urging member 32. Thereby, the end part of the rotating shaft 7 can be press-contacted with the sliding resistance generation member 21 only by making the link member 31 into the biasing member 32, without increasing a number of parts. Therefore, the structure of the wind direction adjusting device 1 can be prevented from becoming complicated.

  Moreover, it becomes possible to obtain the operation force of the louvers 4 to 6 without depending on the frictional force generated at the connecting portion between the link member 31 and the louvers 4 to 6. Furthermore, the axial backlash of the louvers 4 to 6 can be suppressed by pressing the end of the rotating shaft 7 against the sliding resistance generating member 21 by the urging member 32. Furthermore, it becomes possible to eliminate the need for strict dimensional management of the pitch between the rotating shafts 7 of the plurality of louvers 4 to 6 and the pitch between the shaft hole portions 11 of the outlet member 3.

  (Effect 3) The biasing member 32 may be a leaf spring 41. As a result, the end of the rotating shaft 7 can be stably brought into pressure contact with the sliding resistance generating member 21. Further, by using the leaf spring 41 for the urging member 32, it is possible to effectively prevent the operating force from changing due to environmental factors such as a temperature change and a dimensional change due to the temperature change. Further, the leaf spring 41 can be easily processed into the link member 31. And since the leaf | plate spring 41 is a thin member, the wind direction adjusting apparatus 1 can be installed without enlarging.

  (Effect 4) You may provide the sliding resistance generation member 21 with respect to the rotating shaft 7a of the louver 5 located in the middle of the juxtaposed direction in the louvers 4-6 arranged in parallel. Since the louver 5 located in the middle of the juxtaposed direction is directly operated by hand, when the louver 5 located in the middle is moved, the sliding resistance generated by the sliding resistance generating member 21 is directly applied to the hand as an operating force. Because it is transmitted, the operational feeling can be improved.

  (Effect 5) The louver 5 positioned in the middle of the juxtaposed direction is arranged between the louvers 4 and 6 located on both sides of the juxtaposed direction and the louver 5 located in the middle of the juxtaposed direction. You may interpose in the state which accumulated the elastic force so that it could be urged | biased to the sliding resistance generating member 21 at an axial direction. Thereby, it is possible to install the biasing member 32 without difficulty with the simplest structure.

  (Effect 6) The resistance increasing portion 51 may be provided at the end of the rotating shaft 7a so that the resistance increasing portion 51 is received by the receiving portion 52 of the sliding resistance generating member 21. Thereby, a larger sliding resistance can be generated between the end of the rotating shaft 7 a and the sliding resistance generating member 21. Further, the sliding resistance can be freely set and adjusted by devising the size and shape of the resistance increasing portion 51 and the receiving portion 52.

  For example, the receiving part 52 can be a mortar-shaped recess 55 so that the outer periphery of the resistance increasing part 51 is received by the mortar-shaped recess 55. As a result, the receiving portion 52 has a centering effect that brings the resistance increasing portion 51 to the center by the mortar-shaped concave portion 55, so that it is possible to prevent the shaft 7 from being shaken.

  Further, for example, the receiving part 52 can be made flat to receive the end face of the resistance increasing part 51. Thereby, the receiving part 52 can make the sliding resistance which generate | occur | produces by receiving the end surface of the resistance increasing part 51 in a wide area more.
