Description

The present invention relates to a vehicle air outlet device, and in particular, has a wind direction member that rotates about one axis, and the direction of the blown air is changed by the rotation of the wind direction member. It relates to an improved structure of the outlet device .

  Conventionally, as a type of vehicle air outlet device that blows air into the vehicle interior, a blade (wind direction member) that rotates about one axis is provided in the opening of the housing that opens into the vehicle interior. There is a type that controls the direction of air blown into the passenger compartment. In an air outlet device of this type, generally, an operation member for rotating the blade is provided by an external operation, and the blade is manually moved to an arbitrary position by the operation of the operation member. The direction of the blown air can be adjusted to a desired direction by being rotated (see, for example, Patent Document 1).

  On the other hand, in recent years, for example, a motor in which a blade can be rotated forward and backward in accordance with an on / off operation of an ignition switch in order to meet a demand for improvement in a high-class feeling for an air outlet device mounted on an automobile or the like. The opening of the housing is automatically closed by turning the blade to a preset position by turning off the ignition switch, while the opening of the housing is automatically closed. There is also known an air outlet device having a so-called auto shut mechanism in which an air outlet is automatically opened by rotation of a blade (see, for example, Patent Document 2).

  In the air outlet device having such an auto shut mechanism, the blade automatically closes the opening of the housing when the opening of the housing is once automatically closed and then opened again. It is desirable to be able to return to the original position before being rotated to the right. By doing so, the trouble of adjusting the direction of the blown air by rotating the blade to a desired position again can be saved, and good usability can be exhibited.

  Therefore, in an air outlet device with an auto-shut mechanism, a detection device for detecting the rotational position of the blade, a storage device for storing the rotational position of the blade detected by the detection device, and the storage device are stored. And a control device for controlling the rotational position of the blade when the housing opening is opened after being automatically closed based on the above data. A mechanism in which a mechanism for returning the blade is realized has also been proposed (see, for example, Patent Document 3).

However, since it is necessary to use expensive electronic devices such as a detection device, a storage device, and a control device in order to realize the original position return mechanism of the blade with such a conventional structure, in an air outlet device having such a mechanism, The manufacturing cost will inevitably increase. Therefore, if an attempt is made to add an original position returning mechanism of a blade having a conventional structure to an automobile air outlet device or the like having many air outlets, there is a problem that a greater economic burden is imposed. It was.
Japanese Patent Laid-Open No. 9-164837 JP 2000-247140 A JP 2001-246924 A

Here, the present invention has been made in the background as described above, and the problem to be solved is that a wind direction member provided so as to be rotatable about one axis is provided at an arbitrary rotation position. From one of the rotation directions to a preset position, and then automatically turn to another direction opposite to the one direction. It is an object of the present invention to provide a novel structure of an air outlet device for a vehicle that can be realized at a low cost.

  And in this invention, in order to solve this subject, as a 1st aspect, in the opening part of the housing opened in a vehicle interior, it provides in the opening part of the housing so that a wind direction member can be rotated to one axis | shaft, and this wind direction In a vehicle air outlet device that controls the direction of air blown into the passenger compartment by rotation of a member, (a) driving means for generating a predetermined driving force, and driving of the driving means A driving mechanism for rotating the wind direction member in only one of the rotation directions around the one axis by force; and (b) a biasing force when the wind direction member is rotated in the one direction. The urging means that exerts the urging force to rotate the wind direction member in the other direction opposite to the one direction, and (c) the reciprocating motion that is reciprocated integrally with the rotation of the wind direction member. And (d) engaging the reciprocating member Although the integral operation of the reciprocating member with the wind direction member accompanying the rotation of the wind direction member in the other direction by the biasing force of the biasing means is prevented, the wind direction member by the driving force of the drive mechanism Engaging means for allowing the reciprocating member to integrally operate with the airflow direction member in association with the rotation of the reciprocating member in the one direction; and (e) the engaging means integrally including the engaging means. The reciprocating member is rotated in the direction in which the airflow direction member is rotated in the one direction against the urging force of the urging means by being operated by an operation from outside under the engaged state of the reciprocating member. The gist of the vehicle air outlet device is characterized in that it includes an operating member that activates the motor.

  Moreover, according to the 2nd aspect of the air blower outlet apparatus for vehicles according to this invention, with respect to the said reciprocating member, the said drive mechanism turns this reciprocating member with rotation to the said one direction of the said wind direction member. It has a transmission means for transmitting the driving force of the driving means by engaging in a pressing manner only in the direction in which it is integrally operated, and the wind direction member is moved only in the one direction by the transmission of the driving force by the transmission means. It is comprised so that it can be pressed and rotated.

  Furthermore, according to the 3rd aspect of the air blower outlet apparatus for vehicles according to this invention, while the said reciprocating member and the said operation member each have the opposing part which mutually opposes, the said operation member of this reciprocating member and A projecting pin projecting toward the operating member is integrally formed at the facing portion of the airflow direction member, while the one direction of the wind direction member is opposed to the projecting pin at the facing portion of the operating member with the reciprocating member. An engagement convex portion having an engagement surface that is engaged so as to be able to press the protrusion pin is provided integrally only in a direction in which the reciprocating member is integrally operated along with the rotation of the reciprocating member. The engagement convex portion constitutes the engagement means, and the engagement of the engagement surface of the engagement convex portion with the protruding pin causes the wind direction member to move in the other direction by the biasing force of the biasing means. An integral operation of the reciprocating member with the wind direction member accompanying the rotation Although sealed by, said integral operation with 該風 direction member of the reciprocating member with the rotation of the said one direction for a wind direction member by the driving force of the drive mechanism configured to be allowed.

Furthermore, according to the fourth aspect of the vehicle air outlet apparatus according to the present invention, the wind direction member is rotated in the one direction to a preset position by the drive mechanism, The opening of the housing is configured to be closed by the wind direction member.

  In short, in the first aspect of the vehicle air outlet apparatus according to the present invention described above, the operating member is operated from the outside in a state where the engaging means is engaged with the reciprocating member, and the reciprocating motion is performed. By actuating the member, the wind direction member can be manually rotated in one direction of the rotation direction by an amount corresponding to the operation amount of the operation member, and can be positioned at an arbitrary rotation position. In addition, if the driving force of the drive mechanism is generated instead of such operation of the operation member, the engagement of the engagement means with respect to the reciprocating member is released, and the position is set at an arbitrary rotational position. The squeezed wind direction member can be further automatically rotated in one direction. When the automatic rotation of the wind direction member in one direction by the driving force of the drive mechanism is canceled, the reciprocating member is re-engaged with the engagement means by the biasing force of the biasing means. It can be rotated in the other direction opposite to the one direction until it reaches the position where it is swung, in other words, the position before it is rotated in one direction by the driving force of the drive mechanism.

  For this reason, in the device of the present invention, for example, when the wind direction member is automatically rotated in one direction to a preset position by the driving force of the drive mechanism, the wind direction member is operated. It is automatically rotated in one direction from a state where it is positioned at an arbitrary rotational position by the operation of the member to a preset position in accordance with the generation of the driving force of the driving mechanism. In the moving position, the rotation of the wind direction member in one direction by the driving force of the driving mechanism is eliminated, so that the wind direction member is moved to an arbitrary rotating position before being automatically rotated by the driving force of the driving mechanism. It can be restored.

  Therefore, in the vehicle air outlet apparatus according to the present invention, the wind direction member is automatically rotated from an arbitrary rotation position to a preset position in one of the rotation directions. Then, when automatically rotating in the other direction opposite to the one direction, a mechanism for returning to the original position before the automatic rotation in one direction is simply a predetermined engagement means. Only a relatively inexpensive member such as an operation member, a reciprocating member, or an urging member may be provided at a low cost.

  Therefore, in the vehicle air outlet apparatus according to the present invention as described above, for example, a so-called auto-shut mechanism that automatically opens and closes the opening of the housing by the automatic rotation of the wind direction member is added. In this case, the rotation of the wind direction member is controlled based on the detection device that detects the rotation position of the wind direction member, the storage device that stores the detection value by the detection device, or the data stored in the storage device. The original position return mechanism of the wind direction member can be economically advantageously configured without using any expensive electronic equipment such as a control device. As a result, the high-grade feeling and the usability improvement by the simultaneous addition of both the auto-shut mechanism and the original position return mechanism of the wind direction member can be realized extremely advantageously with excellent economy. .

  Moreover, in the device of the present invention, an automatic swing mechanism that automatically rotates the wind direction member in one direction and the other direction by the driving force of the driving means and the urging force of the urging means can be configured. . Then, by using the original position return mechanism of the wind direction member as described above, the rotational position of the wind direction member in the other direction is set to a preset position. It is possible to set a desired range and direction of the swing range) and the rotation direction (swing direction).

  In the second aspect of the vehicle air outlet apparatus according to the present invention, the drive mechanism can be configured with a relatively simple structure, and the overall structure of the vehicle air outlet apparatus is simplified. Can also be achieved.

  Furthermore, according to the third aspect of the vehicle air outlet apparatus according to the present invention, the special engagement form of the engagement means with respect to the reciprocating member can be reliably realized with a relatively simple structure.

  Furthermore, in the fourth aspect of the vehicle air outlet device according to the present invention, an auto shut mechanism can be advantageously added.

  Hereinafter, in order to clarify the present invention more specifically, the configuration of a vehicle air outlet device according to the present invention will be described in detail with reference to the drawings.

  First, in FIG. 1 thru | or FIG. 3, the air blower apparatus attached to the instrument panel of a motor vehicle as one embodiment of the air blower apparatus for vehicles according to this invention is the front form, the side form, and the longitudinal cross-sectional form. Are respectively schematically shown. As is clear from these drawings, the air outlet device of the present embodiment has a housing 10 and is configured.

  More specifically, the housing 10 is formed of a rectangular cylindrical body that opens forward and backward (in the right direction and the left direction in FIG. 3), and is formed at the main body 11 and one end of the main body 11. It further has a frame 12 having a window portion that is fixed and is slightly smaller than the opening of the main body 11. And in this housing 10, the window part of the frame 12 is made into the air blower outlet 13, and the front opening part 14 of the main body 11 is the state of the frame 12 under the attachment state to the instrument panel which is not shown in figure. While being opened toward the vehicle interior through the air outlet 13, the rear opening 15 of the main body 11 is connected to an air passage (not shown) such as an air conditioner, so that the air conditioner or the like is connected. Is supplied from the air outlet 13 into the vehicle compartment.

  Further, in the front opening 14 of the housing 10, a plurality of longitudinal blades 16 and transverse blades 18 as wind direction members, each having a longitudinal flat plate shape, are positioned on the rear side and the front side, respectively. It is arranged one by one.

  Although not shown in the drawing, the plurality of vertical blades 16 are arranged in a row in parallel with each other and at a predetermined interval in the left-right direction (the direction perpendicular to the paper surface in FIG. 3) as in the prior art. The rotating shafts 20, 20 extending in the vertical direction (the vertical direction in FIG. 3) from both ends in the longitudinal direction are respectively arranged on the upper and lower bottom wall portions 22 of the main body 11 of the housing 10. , 24 are mounted on the housing 10 in a state where they are pivotally supported. The plurality of vertical blades 16 are connected to each other by a vertical blade interlocking plate 26 that extends in the left-right direction and can reciprocate in the left-right direction.

  Further, in the plurality of vertical blades 16, a rod-shaped vertical blade operation knob 28 is integrally formed on the lower rotating shaft 20 located at the center of the arrangement direction toward the front side of the housing 10. It is fixed so that it can rotate integrally. The vertical blade operation knob 28 has a tip 30 as a knob 30, and the knob 30 is a lower part of the four frames of the frame 12 that forms the air outlet 13 of the housing 10. Through the operation hole 32 provided in the side frame portion, it is protruded to the outside (vehicle interior) of the housing 10 and can be picked from the vehicle interior.

  Thus, in the plurality of vertical blades 16, the vertical blade located at the center is obtained by the user (operator) picking the knob 30 of the vertical blade operation knob 28 and rotating it left and right. 16 is rotated in the left-right direction around the rotation shafts 20, 20, and the vertical blade interlocking plate 26 is reciprocated in the left-right direction. All of these are interlocked and can be rotated left and right. The direction of the air blown from the air outlet 13 of the housing 10 can be changed in the left-right direction by such rotation of the plurality of vertical blades 16.

  On the other hand, the plurality of horizontal blades 18 are arranged in parallel with each other and arranged in a line at a predetermined interval in the vertical direction, and are arranged in a line, respectively. Rotating shafts 34 that integrally extend in the left-right direction from the front portions at both ends in the direction are pivotally supported on the left and right side walls 36, 38 in the main body 11 of the housing 10, respectively. It is assembled.

  Further, in each of the horizontal blades 18, as shown in FIG. 4, the connecting pin 33 extends integrally from the rear side portion of the left end portion in the longitudinal direction. The distal end portion of the connecting pin 33 projects to the outside of the housing 10 through an arcuate pin insertion hole 35 extending in the vertical direction and formed on the left side wall portion 36 of the housing 10 corresponding to each connecting pin 33. I'm hurt. Further, the distal end portion of each connecting pin 33 projected to the outside of the housing 10 is disposed outside the left side wall portion 36 of the housing 10 so as to be reciprocally movable in the vertical direction. It is attached to the interlocking plate 40 so as to be rotatable.

  Thus, the plurality of horizontal blades 18 are connected to each other via the horizontal blade interlocking plate 40, and the horizontal blade interlocking plate 40 is reciprocated in the vertical direction, whereby a plurality of horizontal blades are connected. All 18 can be interlocked and rotated upward (in one direction) and downward (in the other direction).

  Here, as shown in FIG. 2 and FIGS. 4 to 7, a lateral blade operation knob 42 as an operation member for rotating the plurality of lateral blades 18 is provided outside the housing 10. When the horizontal blade operation knob 42 is rotated in the vertical direction, the horizontal blade interlocking plate 40 is moved in the vertical direction, and the plurality of horizontal blades 18 are simultaneously rotated.

  That is, the horizontal blade interlocking plate 40 has a substantially long flat plate shape extending in the vertical direction, and a plate-like protrusion 43 protruding to one side in the width direction is integrally formed in the middle portion in the length direction. Is provided. In addition, a round bar-like projecting pin 44 having a relatively short length is integrally projected on the plate-like projecting portion 43. And the state where this horizontal blade interlocking plate 40 was made to oppose the surface on the opposite side to the formation surface of the protrusion pin 44 with respect to the outer surface of the left side wall part 36 of the housing 10 (main body 11) at a predetermined distance. It is arranged.

  In addition, a torsion coil spring 45 as an urging means is disposed between the horizontal blade interlocking plate 40 and the outer surface of the left side wall portion 36 of the housing 10 on which it is opposed. The torsion coil spring 45 is configured to exert a biasing force in a direction in which the torsion coil springs 45 approach each other when both ends thereof are separated from each other. Then, with the torsion coil spring 45 having both ends separated by a predetermined amount, one end of the torsion coil spring 45 is on the outer surface of the left side wall portion 36 of the housing 10 below the position where the horizontal blade interlocking plate 40 is disposed. The other end is fixed to the horizontal blade interlocking plate 40 while being fixed to the fixing pin 46 protruding from the part. As a result, the horizontal blade interlocking plate 40 is always urged downward by the urging force of the torsion coil spring 45.

  On the other hand, as is apparent from FIG. 8, the horizontal blade operation knob 42 has a thick disk shape in which a circular center hole 48 penetrating in the thickness direction is provided in the center portion. On one surface in the vertical direction, the engaging convex portion 50 is provided integrally. Further, the engaging convex portion 50 has a relatively low ridge shape that continuously extends while bending in the substantially radial direction of the lateral blade operation knob 42.

  Further, in the engagement convex portion 50, in the length direction thereof, one end portion located on the front side in the upward rotation direction of the lateral blade operation knob 42 and the other end portion on the opposite side thereof. A portion extending in the radial direction of the horizontal blade operation knob 42 having a disk shape is provided over a predetermined length at the intermediate portion thereof, and is a portion extending in the radial direction. A portion extending in the circumferential direction of the lateral blade operation knob 42 is formed between the one end portion and the intermediate portion so as to be continuous with and connect to the one end portion and the intermediate portion. The surfaces opposite to the central hole 48 side at the one end portion and the other end portion, which are the radially extending portions, are first and second stopper surfaces 52 and 54, respectively. In addition, a surface opposite to the center hole 48 side in the intermediate portion that is a radially extending portion is a pressing engagement surface 56. Further, the surface opposite to the center hole 48 side in the circumferentially extending portion between the pressing engagement surface 56 and the first stopper surface 52 is the pressing engagement surface 56 and the first stopper surface 52. A continuous sliding engagement surface 58 is provided.

  As shown in FIGS. 2 and 4, the lateral blade operation knob 42 having the engagement convex portion 50 as described above is formed on the outer surface side of the left side wall portion 36 of the housing 10. Facing the formation surface of the projecting pin 44 of the lateral blade interlocking plate 40 with a predetermined distance, and the first and second stopper surfaces 52 and 54 and the press engagement surface 56 of the engagement convex portion 50. The projecting pin 44 of the horizontal blade interlocking plate 40 is placed in contact with and formed on the surface on which the sliding engagement surface 58 is formed. And in such an arrangement state, it is attached to the rotating shaft 60 that protrudes from the outer surface of the left side wall portion 36 and extends through the through hole 41 provided in the horizontal blade interlocking plate 40. Further, a part of the horizontal blade operation knob 42 is provided through the operation hole 62 provided in the left frame portion of the four frame portions of the frame body 12 in the housing 10. It is made to project on the interior side surface and can be rotated from the vehicle interior (see FIG. 1).

  As described above, since the horizontal blade interlocking plate 40 is constantly biased downward by the biasing force of the torsion coil spring 45, the protruding pin 44 of the horizontal blade interlocking plate 40 is fixed to the horizontal blade operation knob 42. The engaging convex portion 50 is engaged in a state of pressing it. Further, under the state where each horizontal blade 18 is positioned at the bottom dead center in the vertical rotation, the protruding pin 44 of the horizontal blade interlocking plate 40 is pressed against the engaging convex portion 50 of the horizontal blade operation knob 42. The contact surface 56 is in contact with the end of the mating surface 56 opposite to the sliding engagement surface 58 (see FIG. 4). Furthermore, when each horizontal blade 18 is positioned at the top dead center in the vertical rotation, the protruding pin 44 of the horizontal blade interlocking plate 40 is pressed against the engagement convex portion 50 of the horizontal blade operation knob 42. The end of the mating surface 56 on the side of the sliding engagement surface 58 or the contact position is in contact with the sliding engagement surface 58 (see FIGS. 6 and 7).

  Therefore, here, regardless of the movement position of the horizontal blade interlocking plate 40 in the vertical direction, the engagement state of the protruding pin 44 of the horizontal blade interlocking plate 40 with respect to the engaging convex portion 50 of the horizontal blade operation knob 42 is determined. As long as the horizontal blade operation knob 42 is rotated upward and the engagement position of the projecting pin 44 with respect to the engagement convex portion 50 is not displaced downward, the torsion coil spring 45 is always secured. The downward movement of the lateral blade interlocking plate 40 due to the urging force can be prevented.

  Thus, in this embodiment, as shown in FIGS. 4 to 6, the horizontal blade operation knob 42 is rotated downward (in the direction indicated by the arrow in FIG. 4) from the outside of the housing 10. As a result, the protruding pin 44 of the horizontal blade interlocking plate 40 engaged with the engaging convex portion 50 is pushed up by the engaging convex portion 50, and the horizontal blade interlocking plate 40 is attached to the torsion coil spring 45. It is rotated upward against the force, and all of the plurality of lateral blades 18 are interlocked and rotated upward accordingly. As a result, the direction of the air blown out from the air outlet 13 of the housing 10 is gradually changed downward.

  Further, when the horizontal blade operation knob 42 is rotated upward from the outside (in the direction opposite to the arrow in FIG. 4) from such a state in which each horizontal blade 18 is rotated upward, the engagement is increased. The push-up force with respect to the projecting pin 44 of the joint convex portion 50 is eliminated, and the horizontal blade interlocking plate 40 is rotated downward by the urging force of the torsion coil spring 45. Are interlocked and can be rotated downward. As a result, the direction of the air blown out from the air outlet 13 of the housing 10 can be gradually changed upward.

  Here, when the protruding pin 44 of the horizontal blade interlocking plate 40 is pushed up by the engaging convex portion 50 of the horizontal blade operation knob 42 by the downward rotation operation of the horizontal blade operation knob 42, the horizontal blade is operated. Since the interlocking plate 40 is moved not only upward but also forward, as the lateral blade interlocking plate 40 moves upward, the projecting pin 44 moves on the pressing engagement surface 56 of the engaging convex portion 50. Is slid toward the sliding engagement surface 58 side. As apparent from FIG. 6, when the protruding pin 44 that slides on the pressing engagement surface 56 is positioned at the boundary portion between the pressing engagement surface 56 and the sliding engagement surface 58, The blade interlocking plate 40 is positioned at the top dead center of the reciprocating movement in the vertical direction, and the plurality of horizontal blades 18 are also positioned at the top dead center of rotation in the vertical direction. At this time, the housing 11 The air outlet 13 is completely closed by each lateral blade 18.

Further, the horizontal blade operation knob 42 is further moved downward from the state where the horizontal blade interlocking plate 40 and each horizontal blade 18 are positioned at the top dead center of the reciprocating movement or rotation. It can be made to rotate. In this case, as shown in FIG. 7, the projecting pin 44 is slid on the sliding engagement surface 58 of the engaging convex portion 50. Is extended in the circumferential direction of the horizontal blade operation knob 42, so that the protruding pin 44 is pushed upward by the sliding engagement surface 58 as the horizontal blade operation knob 42 rotates downward. In addition, it is not pulled down and displaced by the biasing force of the torsion coil spring 45. Eventually, the projecting pin 44 is brought into contact with the first stopper surface 52 of the engaging convex portion 50, whereby the downward rotation of the lateral blade operation knob 42 is prevented.

  On the other hand, when the horizontal blade operation knob 42 is rotated upward, the horizontal blade interlocking plate 40 is moved downward by the urging force of the torsion coil spring 45 as described above. 4, when the connecting pin 33 of each horizontal blade 18 is brought into contact with the inner peripheral surface of the end of the pin insertion hole 35 provided in the left wall portion 36 of the housing 10, the horizontal blade interlocks. The plate 40 is positioned at the bottom dead center of the reciprocating movement in the vertical direction, and the plurality of lateral blades 18 are also positioned at the bottom dead center rotating in the vertical direction. The blower outlet 13 will be fully opened.

  Further, the horizontal blade operation knob 42 is further moved upward from the state where the horizontal blade interlocking plate 40 and each horizontal blade 18 are positioned at the bottom dead center of the reciprocating movement or rotation. However, the upward rotation of the horizontal blade operation knob 42 is caused by the projecting pin 44 being brought into contact with the second stopper surface 54 of the engaging convex portion 50. It has been stopped.

  Further, here, the horizontal blade operation knob 42 can be turned up and down with a sliding resistance greater than the biasing force of the torsion coil spring 45 with respect to the turning shaft 60. When the horizontal blade operation knob 42 is stopped at an arbitrary rotational position, the stopped state is maintained against the urging force of the torsion coil spring 45. As a result, the horizontal blade interlocking plate 40 is always rotated downward together with the vertical reciprocation of the horizontal blade interlocking plate 40 even though the horizontal blade interlocking plate 40 is always biased downward by the biasing force of the torsion coil spring 45. The rotation of the horizontal blades 18 is stopped at an arbitrary position corresponding to the operation position of the horizontal blade operation knob 42. Therefore, the vertical direction of the blown air is determined by the horizontal blade operation. It can be maintained in a desired direction according to the operation amount of the knob 42.

  Further, as shown in FIG. 3, here, a damper 64 is provided in the rear opening 15 of the housing 10 so as to be pivotable in the vertical direction, and this damper 64 is also connected to the horizontal blade operation knob 42. It can be turned up and down by a turning operation in the up and down direction.

  That is, the damper 64 is attached to a large-diameter rotating shaft 66 that extends across the left and right side wall portions 36 and 38 of the housing 10. Further, as is apparent from FIG. 2, one end portion of the rotating shaft 66 is protruded to the outside from the left side wall portion 36 of the housing 10, and the outer peripheral surface is opposed to the protruding portion. A fan-shaped gear portion 68 provided with a large number of gear teeth is integrally provided.

  On the other hand, a cam groove 70 is provided on the surface of the lateral blade operation knob 42 on the side opposite to the formation side of the engagement convex portion 50. In the cam groove 70, a substantially half portion located on the front side in the downward rotation direction of the horizontal blade operation knob 42 is a sliding groove 72 extending in the circumferential direction of the horizontal blade operation knob 42. The remaining substantially half is a pressing groove 74 extending in the radial direction of the horizontal blade operation knob 42.

  A rotating arm 76 is provided between the lateral blade operation knob 42 on the outer surface side of the left side wall portion 36 of the housing 10 and the protruding portion of the rotating shaft 66 of the damper 64 so as to be rotatable in the vertical direction. ing. The rotation arm 76 extends from the intermediate portion serving as the rotation center toward the horizontal blade operation knob 42, and extends at a tip portion of the rotation arm 76 so as to face the formation surface of the cam groove 70 of the horizontal blade operation knob 42. And a fan-like gear portion 80 extending from the intermediate portion toward the rotation shaft 66 of the damper 64. In addition, a round bar-shaped sliding pin 82 is integrally projected on a surface of the distal end portion of the extending portion 78 of the rotating arm 76 facing the cam groove 70 forming surface of the lateral blade operation knob 42. In addition, a large number of gear teeth are formed on the outer peripheral surface of the gear portion 80. The sliding pin 82 of the extending portion 78 of the rotating arm 76 is slidably inserted into the cam groove 70 of the lateral blade operation knob 42, while the gear portion 80 is provided with a damper. The gear portion 68 of the 64 rotating shafts 66 is meshed.

  Thus, as shown in FIG. 2, when the horizontal blade operation knob 42 is rotated downward (in the direction of the arrow in FIG. 2), the sliding pin 82 of the rotation arm 76 is moved to the horizontal blade operation knob 42. Along with the sliding in the cam groove 70, the rotating arm 76 is rotated upward, and the rotating shaft 66 of the damper 64 is rotated in the clockwise direction. It can be rotated in the same direction. As a result, the rear opening 15 of the housing 10 is closed by the damper 64. Further, when the horizontal blade operation knob 42 is rotated upward (opposite to the arrow direction in FIG. 2) from such a state, the damper 64 is rotated clockwise, and the housing is The ten rear openings 15 can be opened again.

  Here, when the horizontal blade operation knob 42 is rotated downward, the protruding pin 44 of the horizontal blade interlocking plate 40 is on the pressing engagement surface 56 of the engagement convex portion 50 of the horizontal blade operation knob 42. Are slid, that is, until the air outlet 13 of the housing 10 is fully closed by the horizontal blades 18 from the start of the upward rotation of the horizontal blades 18. The moving pin 82 can be slid in the sliding groove 72 of the cam groove 70 extending in the circumferential direction of the horizontal blade operation knob 42. Then, as apparent from FIG. 7, while the projecting pin 44 is being slid on the sliding engagement surface 58 of the engaging convex portion 50, that is, from the fully closed state of the air outlet 13, the lateral blade While the operation knob 42 is further rotated downward, the slide pin 82 can slide in the pressing groove portion 74 of the cam groove 70 extending in the radial direction of the lateral blade operation knob 42. Yes.

  Thereby, in this embodiment, after the air outlet 13 of the housing 10 is completely closed by the plurality of horizontal blades 18 by the downward operation of the horizontal blade operation knob 42, the housing 10 The closing operation of the rear opening 15 by the damper 64 is performed, and after the rear opening 15 of the housing 10 is completely opened by the turning operation of the horizontal blade operation knob 42 upward. The opening operation of the air outlet 13 is performed.

  By the way, in the air blower outlet apparatus of this embodiment, the opening / closing operation | movement of the air blower outlet 13 of the housing 10 by rotation of the some horizontal blade 18 can also be performed automatically.

That is, as shown in FIGS. 2 and 4, here, an electric motor 84 as a driving unit is fixed to the lower surface of the front side of the lower bottom wall portion 24 of the housing 10. In addition, the electric motor 84 is positioned so that an output shaft 88 having a gear 86 attached to the tip thereof extends to the outer surface side of the left side wall portion 36 of the housing 10.

  On the other hand, on the outer surface of the left side wall portion 36 of the housing 10, a push-up plate 90 as a transmission member is disposed below the horizontal blade interlocking plate 40. The push-up plate 90 is thicker than the horizontal blade interlocking plate 40 and is formed of a flat plate having a fan shape, and a plurality of gear teeth are provided on an outer peripheral surface having an arcuate surface shape.

  The push-up plate 90 is brought into contact with the lower end surface of the lateral blade interlocking plate 40 on the upper surface of the end portion on the gear tooth forming side, and the gear teeth formed on the outer peripheral surface are moved to the output shaft 88 of the electric motor 84. In the state of meshing with the gear 86 attached to the housing, the end portion opposite to the gear tooth forming side is supported to be rotatable in the vertical direction with respect to the outer surface of the left side wall portion 36 of the housing 10. .

  Thus, as shown by a two-dot chain line in FIG. 4, the output shaft 88 of the electric motor 84 is driven to rotate in the clockwise direction by, for example, turning off an ignition switch (not shown). 90 is turned upward, and accordingly, the lateral blade interlocking plate 40 is pushed up by the push-up plate 90 against the urging force of the torsion coil spring 45 and moved upward. As a result, each horizontal blade 18 is rotated upward, and the air outlet 13 of the housing 10 is completely closed by each horizontal blade 18.

  Further, from such a fully closed state of the air outlet 13, the output shaft 88 of the electric motor 84 is driven to rotate counterclockwise by, for example, turning on an ignition switch (not shown). The push-up plate 90 is rotated downward, and the push-up force with respect to the horizontal blade interlocking plate 40 is eliminated. Accordingly, the horizontal blade interlocking plate 40 is moved downward based on the urging force of the torsion coil spring 45, and accordingly, the horizontal blades 18 are rotated downward, and the air in the housing 10 is moved. The outlet 13 can be opened again. That is, here, each of the horizontal blades 18 is rotated upward only by the upward rotation of the push-up plate 90 accompanying the rotational drive of the electric motor 84. As is apparent from this, in the present embodiment, the electric motor 84 and the push-up plate 90 constitute a drive mechanism.

  Here, as described above, the projecting pin 44 provided on the lateral blade interlocking plate 40 is always against the engaging convex portion 50 of the lateral blade operation knob 42 based on the biasing force of the torsion coil spring 45. The horizontal blade interlocking plate 40 is prevented from moving downward due to the biasing force of the torsion coil spring 45.

  Therefore, in the air outlet device of this embodiment, the upward rotation of the horizontal blade interlocking plate 40 by the clockwise rotation drive of the output shaft 88 of the electric motor 84 is the rotational position of the horizontal blade operation knob 42. And the position of the horizontal blade interlocking plate 40, in other words, regardless of the rotational position of each horizontal blade 18, it is allowed regardless of the operation position of the horizontal blade operation knob 42. The closing operation of the air outlet 13 of the housing 10 can be automatically performed.

  On the other hand, by such an automatic operation, the air outlet 13 of the housing 10 is rotated counterclockwise from the state in which the air outlet 13 of the housing 10 is fully closed by the plurality of lateral blades 18. When the horizontal blade interlocking plate 40 is moved downward and the horizontal blades 18 are rotated downward based on the biasing force of the torsion coil spring 45 by driving, the projecting pin of the horizontal blade interlocking plate 40 is rotated. When 44 is re-engaged with the engaging convex portion 50 of the horizontal blade operation knob 42, the downward movement of the horizontal blade interlocking plate 40 is stopped. That is, when the automatic opening operation of the air outlet 13 of the housing 10 is performed, the rotation of each horizontal blade 18 is stopped at a position corresponding to the operation position of the horizontal blade operation knob 42. It is.

  Thus, in the air outlet device of the present embodiment, by rotating the horizontal blade operation knob 42, the plurality of horizontal blades 18 are manually rotated in the vertical direction, and the horizontal blade operation knob. The rotation of each horizontal blade 18 is stopped at a position corresponding to the operation amount of 42, so that the vertical direction of the blown air can be changed to a desired direction. Then, if the electric motor 84 is driven so that the output shaft 88 rotates clockwise, each lateral blade 18 is automatically rotated upward, and the air outlet 13 of the housing 10 is completely closed. It is possible to make it. When the electric motor 84 is driven so that the output shaft 88 rotates counterclockwise from the fully closed state of the air outlet 13, each lateral blade 18 is automatically rotated downward. At the same time, the air outlet 13 of the housing 10 can be opened again, and when the air outlet 13 is opened in this way, the air outlet 13 automatically closes the rotation of each lateral blade 18. It is possible to return to the original position before being performed.

  Thus, in this embodiment, when opening the air outlet 13 from the closed state, the rotational position of each lateral blade 18 can be returned to the original position before the air outlet 13 is closed, Moreover, such a mechanism for returning the horizontal blade 18 to the original position is a horizontal blade operation knob 42 having the engaging convex portion 50, a protruding pin 44 provided on the horizontal blade interlocking plate 40, or a horizontal blade interlocking. Compared to an expensive electronic device such as a torsion coil spring 45 that urges the plate 40 downward, the plate 40 is made of an extremely inexpensive member.

  Therefore, in the air outlet device of this embodiment as described above, the original position return mechanism of the horizontal blade 18, in other words, the mechanism for returning the direction of the blown air to the original position is configured at low cost. It can be done. As a result, better usability can be realized very advantageously with excellent economics.

  Further, in such an air outlet device, by driving the electric motor 84, each horizontal blade 18 is rotated only upward, and the downward rotation of each horizontal blade 18 is caused by the torsion coil spring 45. Therefore, for example, the structure of the electric motor 84 and the lateral force of the horizontal blade 18 can be compared with the case where the horizontal blade 18 is rotated in both the upper and lower directions by one electric motor 84. The structure of the entire mechanism for rotating the blade 18 can be advantageously simplified.

  Further, in the present embodiment, the protruding pin 44 integrally formed with the horizontal blade interlocking plate 40 is merely engaged with the engaging convex portion 50 having a protruding shape provided on the horizontal blade operation knob 42. Thus, when the horizontal blade interlocking plate 40 is prevented from moving downward, the horizontal blade interlocking plate 40 engaged with the horizontal blade operation knob 42 is allowed to move upward. Therefore, the engagement structure of the horizontal blade interlocking plate 40 with the horizontal blade operation knob 42 is realized with a relatively simple structure.

  The specific configuration of the present invention has been described in detail above. However, this is merely an example, and the present invention is not limited by the above description.

  For example, the shape of the housing 10, the number and shape of the vertical blades 16 and the horizontal blades 18 disposed therein, the support form, and the like are not limited to those shown in the above embodiment, but the air outlet It should be set appropriately depending on the arrangement position of the apparatus and the required function.

  Further, if the horizontal blade operation knob 42 as the operation member is disposed at a position where it does not interfere with the air outlet 13 of the housing 10 being completely blocked by the rotation of the horizontal blade 18, the horizontal blade operation knob 42 is disposed. The position is not particularly limited.

  Further, instead of the horizontal blade 18, the vertical blade 16 is rotated in one direction by the driving force of the electric motor 84 and is rotated in the other direction by the urging force of the torsion coil spring 45. You may comprise. Of course, in that case, the vertical blade operation knob 26 and the vertical blade interlocking plate 26 have the same structure as the horizontal blade operation knob 42 and the horizontal blade interlocking plate 40.

  Furthermore, the urging means for urging the wind direction member so as to be rotated in the other direction is not limited to the torsion coil spring 45 illustrated as an example. It will be selected and used.

  The attachment structure, attachment position, number of attachments, and the like of the urging means are not limited to those shown in the embodiment. That is, for example, even when the torsion coil spring 45 shown as an example is employed as the urging means, the torsion coil spring 45 is configured to exert an urging force when both ends thereof are approached. In addition, one end of the torsion coil spring 45 is fixed to the horizontal blade interlocking plate 40, while the other end is fixed to the horizontal blade operation knob 42 so that each horizontal blade 18 rotates downward. It is also possible to be biased in the direction of movement.

  In the above-described embodiment, the push-up plate 90 serving as a transmission unit that meshes with the gear 86 attached to the output shaft 88 of the electric motor 84 serving as the drive unit rotates upward as the electric motor 90 rotates. By being moved, the horizontal blade interlocking plate 40 is pushed up by the push-up plate 90 and moved upward. For example, the rotation with respect to the output shaft 88 of the electric motor 84 is rotated. A member that pushes up the horizontal blade interlocking plate 40 as it is driven is directly attached, or a rack that meshes with a gear 86 that is attached to the output shaft 88 of the electric motor 84 is provided in the horizontal blade interlocking plate 40. Even if the lateral blade interlocking plate 40 is moved upward by the driving force of the electric motor 84, It is not permissible etc..

  Further, as the horizontal blade operation knob 42 as the operation member, instead of the rotation type (rotation type) as shown in the embodiment, a movement type that can be reciprocated in the vertical direction is appropriately used. It can be adopted.

  Further, it is provided integrally with the horizontal blade operation knob 42 which is an operation member, and the operation in one direction of the horizontal blade interlocking plate 40 which is a reciprocating member is prevented, but the operation in the other direction is allowed. The engagement structure and the arrangement structure of the engagement convex portion 50 as the engagement means engaged with the horizontal blade interlocking plate 40 with respect to the horizontal blade interlocking plate 40 are not particularly limited to those illustrated. Needless to say.

  Furthermore, in the said embodiment, although the air blower outlet 13 was comprised in the window part of the frame 12 fixed to the front opening part 14 of the main body 11 of the housing 10, such a frame 12 is provided. Of course, the air outlet 13 can be formed at the front opening 14 of the main body 11 of the housing 10.

  In addition, in the said embodiment, although the specific example of what applied this invention with respect to the air blower outlet attached to the instrument panel of a motor vehicle was shown, this invention is other than the instrument panel of a motor vehicle. Of course, the present invention can be advantageously applied to any of the attached air outlet device and the air outlet device installed in a vehicle other than the automobile.

  In addition, although not enumerated one by one, the present invention can be carried out in a mode to which various changes, modifications, improvements, etc. are added based on the knowledge of those skilled in the art. It goes without saying that all are included in the scope of the present invention without departing from the spirit of the present invention.
