Description

  The present invention relates to a register device for blowing out air from an air conditioner to a vehicle compartment in a vehicle.

  The vehicle register device comprises a register body having an air passage and a fin assembly disposed in the air passage. The fin assembly includes, for example, a plurality of vertically spaced apart and parallel parallel fins extending in the left and right direction, and connecting links for interlocking the fins. When the central fin of the fin assembly is rotated by the operation of the operation knob, the other fins are also rotated through the connection link, whereby the blowout direction can be adjusted up and down.

  As described above, various vehicle registers capable of executing not only the normal blowing mode in which the blowing direction can be adjusted but also the diffusion blowing mode in which the angular range of the blowing is expanded have been developed.

  The register device of Patent Document 1 can switch between the normal air blowing mode and the diffusion air blowing mode by a simple operation of moving the mode switching knob (operation member for mode switching) linearly in the axial direction of the register body. . Although a plurality of embodiments are disclosed in Patent Document 1, a second embodiment having a configuration similar to that of the present invention will be described with reference to FIGS. 9 to 12 of Patent Document 1. The basic configuration is also referred to FIG. 1 and FIG. 2 showing the first embodiment.

  A connecting link mechanism connecting the plurality of fins has a center link and upper and lower side links. The center link is pivotally connected to the central fin. Two upper fins are rotatably connected to the upper side link. Two lower fins are rotatably connected to the lower side link.

  Arc-shaped restriction holes are formed in the upper and lower portions of the center link. The connecting shaft of the third fin from the top is inserted into the upper restriction hole of the center link and the connecting hole formed at the lower end of the upper side link. The connecting shaft of the third lower fin is inserted into the lower limit hole of the center link and the connecting hole formed at the upper end of the lower side link. Thus, the upper and lower side links are connected to the center link so as to be vertically movable by the amount of the restriction hole.

  A guide link is connected to the back end of the mode switching knob via a short relay link. The guide link moves in the axial direction together with the mode switching knob, but is vertically movable with respect to the mode switching knob.

The guide link is connected to the center link so as to be relatively movable in the front-rear direction and incapable of relative movement in the vertical direction.
Guide grooves are formed in the upper and lower portions of the guide link. The guide groove has a parallel groove linearly extending along the axial direction of the resistor body and an inclined cam groove connected to the blowout side of the parallel groove. The connecting shaft of the third fin from the top is inserted into the upper guide groove, and the connecting shaft of the third fin from the lower is inserted into the lower guide groove.

  In the register device of Patent Document 1, when the mode switching knob is at a position where it protrudes to the vehicle compartment side (normal air blowing mode position), all the fins are parallel to execute the normal air blowing mode. When the center fin is turned by the operation knob (the operation member for inclination adjustment), the center link moves in the vertical direction. At this time, the upper and lower side links move up and down together with the center link. As a result, the upper and lower three fins connected to the upper and lower side links interlock with the central fin to adjust the blowing direction.

  In the normal blowing mode, if the mode switching knob is pushed while the fins are horizontal and blow out toward the center in the vertical direction, the guide link moves to the back, but the center link does not move. With the movement of the guide link to the back, the connecting shaft of the third fin from the top and the third fin from the bottom move along the parallel groove of the guide link to reach the cam groove. Further, when the guide link moves further, these connecting shafts move along the inclination of the cam groove, and the cam action of these cam grooves moves the upper side link downward and the lower side link upward In order to move to, the upper and lower fins spread in the blowout direction and switch to

  In the normal blowing mode, when the fins are vertically inclined and blown upward or downward and the mode switching knob is pushed, the fins are horizontal while the connecting shaft moves in the parallel grooves of the guide grooves. Corrected to posture. As a configuration for this correction, the wall of the register body is formed with a pair of cam surfaces facing each other in the vertical direction. The cam surfaces are inclined away from each other in the blowing direction.

  When the fin is in the upward position, the lower end of the guide link is in contact with the lower cam surface. When the guide link moves backward by pushing the mode switching knob, the lower end of the guide link moves along the lower cam surface, and the guide link moves upward accordingly, so the center link and the upper and lower sides move up and down. Side links also move upwards. As a result, the fins are returned to the horizontal position. Immediately after this, the connecting shaft reaches the inclined cam groove. Further movement of the guide link to the back spreads the fins in the blowout direction as described above.

  When the fin is in the downward position, the upper end of the guide link is in contact with the upper cam surface. When the guide link is moved backward by the pressing operation of the mode switching knob, the upper end of the guide link moves along the upper cam surface, and the guide link moves downward accordingly, so the center link and the upper and lower The side link also moves downward. As a result, the fins are returned to the horizontal position. Immediately after this, the connecting shaft reaches the inclined cam groove. Further movement of the guide link to the back spreads the fins in the blowout direction as described above.

JP 2002-293133 A

  In the register device of Patent Document 1, when the fins are switched to the diffusion blowing mode when the fins are in the upward position in the normal blowing mode, the upper fins are once turned to the horizontal position and then pivot upward again. When the fins are switched to the diffusive blowing mode when the fins are in the downward position, the lower fins rotate downward again after being once returned to the horizontal position. As such, useless movement occurs in the fins.

In addition, in order to temporarily set the fins in the horizontal position by the cam action of the cam surface of the register body, it is necessary to set the parallel groove of the guide link long, and the moving stroke of the mode switching knob must be set long. There was a limit to improving sex.
When the moving stroke of the mode switching knob is set short, the inclination angle of the cam groove becomes steep, and a large force is required for the mode switching operation by the mode switching knob, so the operability is lowered.

The mode switching mechanism is
An operation member for mode switching which is supported on the register body so as to be linearly movable between a normal air blowing mode position and a diffusive air blowing mode position along its axial direction;
The back end portion of the mode switching operation member is coupled so as to be moved in the axial direction together with the mode switching operation member and to allow movement of drawing an arc locus in the first direction, and further, A relative movement of the register body in the axial direction relative to the center link, wherein the relative movement in the first direction is disabled, and the guide link is connected;
The formed in the wall of said register main body, a first cam surface inclined relative to the axis of said register body with Ru arranged on the one side, are arranged on the other side as to oppose the first cam surface A second cam surface inclined in a direction opposite to the first cam surface with respect to the axis of the register body;
Equipped with
The guide link has the first sliding portion on the one side and the second sliding portion on the other side, and also has the first cam groove on the one side and the second cam groove on the other side. The first and second cam grooves are inclined in opposite directions with respect to the axial direction of the register body, the first cam groove is inclined in the same direction as the second cam surface, and the second cam groove is inclined in the same direction. Inclined in the same direction as the first cam surface, and the first and second follower pins are respectively engaged with the first and second cam grooves,

It is located at a position closer to the center link from the connection point with the fin on the other side.
According to the above configuration, since the cam action of the cam groove is received by the follower pin separated from the connection point of the side link and the fin, the configuration can be simplified.

Preferably, an arc-shaped engagement hole extending in the first direction is formed at the back end of the mode switching operation member, and the guide link engages the engagement convex portion engaged with the engagement hole. Have.
According to the above configuration, no additional link is required between the mode switching operation member and the guide link, and the configuration can be simplified.

  The blowout side fin assembly 20 has, for example, three (plural) fins 21 and a connection link (not shown) connecting the fins 21. The fins 21 have an elongated plate shape extending in the vertical direction (first direction), and are disposed apart from each other in the horizontal direction (vehicle width direction; second direction).

The fins 21 are supported by the upper and lower walls of the main register body 1 so as to be rotatable about pivot axes extending in the vertical direction via pivot shafts 21a formed at the upper and lower ends thereof.
The three fins 21 have, for example, a connecting shaft 21b at the upper end thereof, and these connecting shafts 21b are rotatably connected to connecting links (not shown) extending in the left and right direction.

An operation knob 40 (an operation member for adjusting inclination) is attached to, for example, the central fin 21 among the three fins 21. The operation knob 40 is pivotally supported by a main portion 41 slidably supported in the vertical direction by the central fin 21 and a pivoting axis extending in the vertical direction at the far end of the main portion 41. And an engaging portion 42. The engagement portion 42 has a pair of upper and lower engagement pieces 42 a that protrude toward the back.
By holding the operation knob 40 by hand and turning the center fin 21 to the left and right, all the fins 21 turn in the same direction via the connection link, thereby adjusting the blowing direction to the left and right it can.

The back side fin assembly 30 has a plurality of, for example, five fins 31 and a connecting link mechanism 35 for connecting the fins 31.
The fins 31 have an elongated plate shape extending in the left-right direction, and are disposed apart from each other in the up-down direction. The fin 31 has a pivot shaft 31 a at the center in the width direction of both left and right ends. The fins 31 are supported on the left and right side walls of the main register body 10 so as to be rotatable about a rotation axis extending horizontally to the left and right via the pair of rotation shafts 31 a.

  The right end portion (right end portion in the vehicle width direction) of the fin 31 has a boss portion 31b on the lower surface at a position spaced rearward from the pivot shaft 31a, and the boss portion 31b protrudes to the right in the vehicle width direction The connecting shaft 31c is formed.

  The connection link mechanism 35 has a center link 36, and upper side links 37 (first side links) and lower side links 38 (second side links) disposed above and below.

  As shown in FIGS. 4 and 5, at the center of the center link 36 in the vertical direction, one connection hole 36a is formed on the outlet side, and two slide portions 36b that project to the right in the vehicle width direction on the back side. Is formed. Further, at upper and lower portions of the center link 36, restriction holes 36c and 36d described later are formed.

  As shown in FIG. 1A, the connecting shaft 31c of the fin 31 (selection fin) at the center in the vertical direction is fitted in the connecting hole 36a of the center link 36. Thus, the center link 36 and the central fin 31 are connected so as to be relatively rotatable around a pivot axis extending in the left-right direction.

As shown in FIGS. 4 and 5, the upper side link 37 has two connection holes 37a and 37b which are vertically separated from each other, and has a follower pin 37c at the lower end thereof projecting to the right in the vehicle width direction.
As shown in FIG. 1A, the connecting shafts 31c of the upper two fins 31 are fitted in the connecting holes 37a and 37b of the upper side link 37. As shown in FIG. Thus, the upper side link 37 and the upper two fins 31 are connected so as to be relatively rotatable about a pivot axis extending in the left-right direction. The upper two fins 31 are always rotated simultaneously in the same direction via the upper side link 37.

As shown in FIGS. 4 and 5, the lower side link 38 has two connecting holes 38a and 38b spaced apart vertically and has a follower pin 38c projecting to the right in the vehicle width direction at its upper end. .
As shown in FIG. 1A, connecting shafts 31c of the two lower fins 31 are fitted in the connecting holes 38a and 38b of the lower side link 38. As shown in FIG. Thus, the lower side link 38 and the lower two fins are connected so as to be relatively rotatable around a pivot axis extending in the left-right direction. The lower two fins 31 are always rotated simultaneously in the same direction via the lower side link 38.

As shown in FIG. 1A, the connecting shaft 31 c of the second top fin 31 is also engaged with the upper restriction hole 36 c of the center link 36. The restriction hole 36 c describes an arc centered on the pivot shaft 31 a of the second fin 31 from the top.
Similarly, the connecting shaft 31 c of the second lowermost fin 31 is also engaged with the lower restriction hole 36 d of the center link 36. The restricting hole 36 d describes an arc centered on the pivot shaft 31 a of the second lowermost fin 31.
Since the connecting shaft portion 31c engages with the restriction holes 36c and 36d of the center link 36, rattling between the center link 36 and the side links 37 and 38 can be suppressed. The restriction holes 36c and 36d may be omitted.

  As shown in FIG. 1A, the central fin 31 has an engagement shaft 31d at the end on the blowout side in the central portion in the vehicle width direction, and the engagement shaft 31d is a pair of operation knobs 40. Is engaged with the engagement piece 42a. The central fin 31 has a notch (not shown) for receiving the engagement piece 42a in a region adjacent to the engagement shaft 31d.

In the state where the five fins 31 are parallel to each other (normal air flow mode), as described later, the connecting link mechanism 35 is integrated, so when the operation knob 40 is slid up and down, not only the center fin 31 The upper two fins 31 and the lower two fins 31 are simultaneously pivoted in the same direction through the link mechanism 35, whereby the blow-out direction can be adjusted up and down.

  Next, the mode switching mechanism S will be described with reference to FIG. 2, FIG. 4 and FIG. The air blowing mode switching mechanism S includes a guide bush 50, a mode switching knob 60 (mode switching operation member), and a guide link 70.

  The guide bush 50 is fitted and fixed in a shallow recess formed in the right wall of the register body 10, and constitutes a part of the right wall. In addition, the code | symbol 59 of FIG. 4 shows the axial hole for supporting the rotational axis 31a of the fin 31. As shown in FIG.

  A recess 51 is formed at the back of the guide bush 50. The upper side surface 52 and the lower side surface 53 of the recess 51 are inclined so as to spread toward each other in the blowing direction. That is, the upper side surface 52 is inclined upward toward the outlet side, and the lower side surface 53 is inclined downward toward the outlet side.

As shown in FIG. 2A, the upper side surface 52 of the recess 51 is configured by connecting a cam surface 52a (first cam surface) on the outlet side and a receiving surface 52b on the rear side. The inclination angle Θx of the cam surface 52a with respect to the central axis of the register body 10 is smaller than the inclination angle of the receiving surface 52b.
The lower side surface 53 of the recess 51 is also configured by connecting a cam surface 53a (second cam surface) on the outlet side and a receiving surface 53b on the rear side. The inclination angle Θy of the cam surface 53a with respect to the central axis of the register body 10 is smaller than the inclination angle of the receiving surface 53b.

As shown in FIG. 4, a guide recess 55 is formed at the outlet end of the guide bush 50. The mode switching knob 60 is slidably supported by the guide recess 55 in the front-rear direction (the axial direction of the register body 10).
The blowout side end of the mode switching knob 60 is provided as the operation unit 61. The operation portion 61 protrudes rearward (in the direction of the passenger compartment) from the end face of the guide bush 50 on the outlet side.

  As shown in FIGS. 4 and 5, the mode switching knob 60 has a head portion 62 with a wide end at the back end, and in the head portion 62, an arc-shaped engagement hole 63 extending in the vertical direction is provided. It is formed.

  The guide link 70 is connected to the head portion 62 of the mode switching knob 60. That is, an engagement convex portion 71 having a circular cross section protrudes horizontally to the right in the vehicle width direction at a portion on the blowout side of the guide link 70, and the engagement convex portion 71 is an engagement hole 63 of the mode switching knob 60. Is engaged. Thus, the guide link 70 moves in the front-rear direction together with the mode switching knob 60, but can move up and down so as to draw a circular arc with respect to the mode switching knob 60.

The guide link 70 is provided with sliding portions 72 and 73 (first and second sliding portions) which play a role to be described later.
The guide link 70 gradually narrows in depth, and the upper and lower edges thereof are provided as linear abutments 74,75. The inclination angle of the upper contact portion 74 is equal to the inclination angle of the upper receiving surface 52b, and the inclination angle of the lower contact portion 75 is equal to the inclination angle of the lower receiving surface 53b.

  The guide link 70 has a pair of upper and lower slits 76 at its back side portion. The slits 76 extend in the front-rear direction (the axial direction of the register body 10), and the slide portion 36b of the center link 36 described above is slidably engaged with the slits 76. Thus, the guide link 70 and the center link 36 move together in the vertical direction, but relative movement in the front-rear direction is possible.

  Furthermore, in the guide link 70, a pair of upper and lower guide grooves 77, 78 in a slit shape is formed. As shown in FIGS. 2A and 5, the upper guide groove 77 is continuous with a linear cam groove 77a (first cam groove) that inclines downward toward the outlet side and an end on the back side of the cam groove 77a. A parallel groove 77b and a parallel groove 77c connected to the end of the cam groove 77a on the air outlet side are provided. The parallel grooves 77 b and 77 c are parallel to the axis of the register body 10.

  The lower guide groove 78 is continuous with a linear cam groove 78a that inclines upward toward the outlet side, a parallel groove 78b connected to the end on the back side of the cam groove 78a, and an end on the outlet side of the cam groove 78a. And parallel grooves 78c. The parallel grooves 78 b and 78 c are parallel to the central axis of the register body 10.

  The inclination angle of the upper cam groove 77a is equal to the inclination angle Θy of the lower cam surface 53a of the guide bush 50, and the inclination angle of the lower cam groove 78a is equal to the inclination angle Θx of the upper cam surface 52a.

  The follower pin 37 c of the upper side link 37 is engaged with the upper guide groove 77. The follower pin 38c of the lower side link 38 is engaged with the lower guide groove 78.

  The operation of the back side fin assembly 30 of the register device having the above configuration will be described in detail. FIGS. 1A and 2A show a state in which the mode switching knob 60 is at the drawing position (normal air blowing mode position) and the normal air blowing mode is being executed. Since the mode switching knob 60 is at the pullout position, the guide link 70 is at the blowout side. Therefore, the follower pins 37 c and 38 c of the upper side link 37 and the lower side link 38 are located at the back ends of the cam grooves 77 a and 78 a of the guide link 70.

  Since the slide portion 36b of the center link 36 is engaged with the slit 76 of the guide link 70, the guide link 70 and the center link 36 are in a state where they can not move up and down. Further, since the follower pins 37c and 38c are engaged with the cam grooves 77a and 78a, the side links 37 and 38 are connected to the guide link 70 so as not to move up and down. As a result, the center link 36 and the side links 37 and 38 are integrally connected via the guide link 70 so as not to move in the vertical direction, and in this connection state, the five fins 31 are in parallel.

As shown in FIGS. 1A and 2A, in a state where the center link 36 and the guide link 70 are positioned at the center in the vertical direction, all the fins 31 are in a horizontal posture in parallel with the central axis of the register body 10. In this state, the air from the air conditioner is blown out toward the central portion in the vertical direction, and the blowout direction is adjusted to the left and right by the blowout side fin assembly 20.
In this blowing state, the engagement convex portion 71 of the guide link 70 is located at the center of the engagement hole 63 of the mode switching knob 60.

  In the normal blowing mode, the connecting shaft 31c of the second fin 31 from the top is located at the upper end of the upper restriction hole 36c of the center link 36, and the connecting shaft 31c of the second fin 31 from the bottom is the lower side of the center link 36. Located at the lower end of the restriction hole 36d.

  In the normal blowing mode, as shown in FIG. 1B, when the operation knob 40 is slid upward along the center fin 21 of the outlet side fin assembly 20, the center fin 31 of the back side fin assembly 30 is directed toward the outlet direction. Turn counterclockwise in the figure so as to face upward. Along with this, the center link 36 and the guide link 70 move downward. Also, with the downward movement of the guide link 70, the upper side link 37 and the lower side link 38 also move downward. As a result, the upper two fins 31 and the lower two fins 31 rotate counterclockwise. In this manner, all the fins 31 are in an upward position toward the blowout direction, and air can be blown upward.

Since the side links 37 and 38 move downward while drawing a locus of arcs, the guide links 70 also move downward while drawing a locus of arcs. In the course of this movement, the engagement convex portion 71 of the guide link 70 moves along the arc of the engagement hole 63 of the mode switching knob 60 and reaches its lower end.
When the fins 31 are in the upward position at the maximum angle, the lower slide portion 73 of the guide link 70 is in contact with the lower cam surface 53 a of the guide bush 50 as shown in FIG. 2B.

When the operation knob 40 is slid downward, the central fin 31 is rotated clockwise in FIG. 1A, and the center link 36 is moved upward, conversely to the above, with which the guide link 70 and the upper side link 37, the lower side link 38 also moves upward, so the upper two fins 31 and the lower two fins 31 also rotate clockwise, and all the fins 31 are in a downward posture toward the blowing direction. , Can be blown downward.
When the fin 31 is in the downward posture at the maximum angle, the engagement convex portion 71 of the guide link 70 reaches the upper end of the engagement hole 63 of the mode switching knob 60, and the upper sliding portion 72 of the guide link 70 is a guide It is in contact with the upper cam surface 52 a of the bush 50.

  The case of switching from the state of blowing out toward the central portion in the vertical direction in the normal mode shown in FIGS. 1A and 2A to the diffusion blowing mode shown in FIGS. 1C and 2C will be described. When the mode switching knob 60 is pushed toward the push-in position (the diffusion blowing mode position), the guide link 70 moves backward.

  When the guide link 70 moves backward, the follower pins 37c and 38c of the upper side link 37 and the lower side link 38 move along the cam grooves 77a and 78a of the guide grooves 77 and 78, respectively. The cam action of the cam grooves 77a and 78a on the follower pins 37c and 38c causes the upper side link 37 to move downward, and the lower side link 38 to move upward.

Along with the downward movement of the upper side link 37, the upper two fins 31 connected to the upper side link 37 via the connecting shaft 31c rotate counterclockwise to move in the blowing direction. Tilt upwards.
With the upward movement of the lower side link 38, the lower two fins 31 connected to the lower side link 38 via the connecting shaft 31c rotate clockwise, in the blowout direction Tilt downwards.

  As described above, since the upper two fins 31 are inclined upward and the lower two fins 31 are inclined downward, the air from the air conditioner spreads up and down and blows out. The center fin 31 is maintained horizontal.

  Pushing of the mode switching knob 60 is limited by the abutment portions 74 and 75 of the guide link 70 contacting the receiving surfaces 52b and 53b of the guide bushes, respectively. At the position where the mode switching knob 60 is pressed, the inclination angles of the upper two fins 31 and the lower two fins 31 become maximum, and the diffusion and blowing within the maximum angle range are executed.

  When the mode switching knob 60 reaches the pressing position, the follower pins 37c and 38c of the side links 37 and 38 reach the ends of the cam grooves 77a and 78a of the guide link 70 on the blowing side.

  At the time of switching from the normal air blowing mode to the diffusion air blowing mode, the connecting shaft 31c of the second upper fin 31 moves from the upper end to the lower end of the upper restriction hole 36c of the center link 36, and the second lower fin The connecting shaft 31c of 31 moves from the lower end of the lower restriction hole 36d of the center link 36 to the upper end.

  When switching from the diffusion blowing mode shown in FIGS. 1C and 2C to the normal blowing mode shown in FIGS. 1A and 2A, the mode switching knob 60 may be pulled to return to the extraction position. The movement of each component in this case is opposite to that described above, but can be easily estimated, so the description is omitted.

  In the present embodiment, when the mode switching knob 60 is at the drawing position (normal blowing mode position), the follower pins 37c and 38c are located at the far end of the cam grooves 77a and 78a and at the pressing position (diffusion blowing mode position). The cam grooves 77a and 78a are located at the ends on the blowout side. Therefore, the cam action by the cam grooves 77a and 78a works in the whole area of the movement stroke between the pulling out position and the pushing position of the mode switching knob 60.

  Next, as shown in FIGS. 1B and 2B, the case of switching to the diffusion blowing mode in FIGS. 1C and 2C in a state where the air is blown upward in the normal blowing mode will be described. Also in this case, the mode switching knob 60 is pushed in. Then, the guide link 70 moves to the back, and the lower slide portion 73 of the guide link 70 slides along the lower cam surface 53 a, so the guide link 70 moves upward. The cam action by the lower cam surface 53a works in the entire area of the movement stroke between the pull-out position and the push-in position of the mode switching knob 60.

  The upward movement of the guide link 70 by the cam action of the cam surface 53a basically causes the upward movement of the center link 36 and the side links 37, 38, and thus the clockwise rotation of the fins 31. Bring. However, at the same time as the cam action by the cam surface 53a occurs, the cam action to the follower pins 37c, 38c by the cam grooves 77a, 78a of the guide link 70 described above works. The cam action by the cam groove 77a brings about the downward movement of the upper side link 37 and the upward movement of the lower side link 38, and thus the counterclockwise rotation of the upper two fins 31 and the lower side. The pivoting of the two fins 31 in the clockwise direction is brought about.

  As apparent from the above description, the camming action of the lower cam surface 53a and the camming action of the upper cam groove 77a are offset. In particular, in the present embodiment, since the inclination angle Θy of the cam surface 53a and the inclination angle of the cam groove 77a are equal, the two cam actions completely cancel each other, so the upper side link 37 is kept stationary, and hence the upper 2 The fins 31 are maintained in the upward posture at rest.

  The cam action of the cam surface 53a and the cam action of the lower cam groove 78a are added. Therefore, the lower side link 38 moves upward at a stretch, and the lower two fins 31 largely rotate from the upward posture to the downward posture.

  The guide link 70 moves upward to return to the vertical center position by the cam action of the cam surface 53a, and the center link 36 also returns to the central position accordingly, so that the central fin 31 returns to the horizontal posture.

  As described above, it is possible to shift from the upward blowing state in the normal blowing mode to the diffusion blowing mode. In this case, the upper two fins 31 do not move uselessly and remain stationary in the upward posture, and the lower two fins 31 change to the downward posture, so that the user does not feel uncomfortable and diffuse. It is possible to switch to the mode.

  When the upward angle of the fins 31 is smaller than the maximum angle, the sliding portion 73 of the guide link 70 is away from the cam surface 53a. Since the upper side link 37 is moved downward by the cam action of the cam grooves 77a and 78a until the sliding portion 73 abuts on the cam surface 53a by the pressing of the mode switching knob 60, the upper two fins 31 are further Increase the upward angle. On the other hand, as the lower side link 38 moves upward, the lower two fins 31 are reduced in the upward angle.

  Further, when the mode switching knob 60 is pushed in and the sliding portion 73 contacts the cam surface 53a, the upward angle of the upper two fins 31 is maximum. The subsequent action is the same as described above, and the upper two fins 31 stand still in the maximum upward posture, and the lower two fins 31 are turned to the downward posture.

  When switching to the diffusion blowing mode in the normal blowing mode in the downward blowing state, the cam action on the sliding portion 72 of the guide link 70 by the upper cam surface 52a and the cam grooves 77a and 78a of the guide link 70. Due to the cam action of the follower pin 37c, the two upper fins 31 rotate from the downward posture to the upward posture while the lower two fins 31 stand still in the downward posture.

  In the present embodiment, the parallel grooves 77b, 77c, 78b and 78c of the guide grooves 77 and 78 are formed to absorb a manufacturing error. That is, when there is a manufacturing error, when the mode switching knob 60 is in the normal blowing mode position, the follower pins 37c, 38c enter the parallel grooves 77b, 78b, or when the mode switching knob 60 is in the diffusion blowing mode position. The follower pins 37c and 38c enter the parallel grooves 77c and 78c.

The present invention is not limited to the above embodiment, and various aspects are possible.
For example, the follower pins 37c and 38c may be designed to be positioned in the parallel grooves 77b and 78b when the mode switching knob 60 is in the normal blowing mode position. In this case, the cam action of the cam grooves 77a and 78a does not work in the initial short stroke in the pushing process of the mode switching knob 60. In this case, it is preferable that the sliding portion 72 (or 73) of the guide link 70 be separated from the cam surface 52a (or 53a) by the initial streak while the fins 31 are maximally inclined in the normal blowing mode. This is to make the stroke area in which the cam action of the cam grooves 77a and 78a act and the stroke area in which the cam action of the cam surface 52a (or 53a) act.

  The follower pins 37c and 38c may be designed to be positioned in the parallel grooves 77c and 78c when the mode switching knob 60 is in the diffusion blowing mode position. In this case, when switching from the normal blowing mode to the diffusion blowing mode, the mode switching knob 60 can be further pushed to the diffusion blowing mode position after the cam action of the cam grooves 77a and 78a is finished.

  The push-in position of the mode switching knob 60 may be set to the normal blowing mode position, and the drawing position may be set to the diffusion blowing mode position. In this case, the direction of the cam groove and the cam surface is opposite to that of the above embodiment.

The follower pin of the side link may be a connecting shaft connecting the side link and the fin.
A plurality of central fins may be connected to the center link. One fin may be connected to the side link.

The stroke area in which the cam action of the cam groove acts and the stroke area in which the cam action of the cam surface acts may overlap only partially without completely overlapping. Further, the inclination angles of the first cam groove and the second cam surface may not be equal, or the inclination angles of the first cam groove and the second cam surface may not be equal. Even in such a case, it is possible to suppress the useless movement of part of the fins in the inclined state in the normal blowing mode.

The wind direction may be adjusted in the vertical direction by the blowout side fin assembly, and the wind direction may be adjusted in the left and right direction by the back side fin assembly. In this case, the blowout direction spreads to the left and right by adjusting the back side fin assembly and executing the diffusion blowing mode.
In the above embodiment, the diffusion blowing mode is performed by adjusting the back side fin assembly, but the blowing side fins assembly may be adjusted to execute the diffusion blowing mode.
In the above embodiment, although two sets of fin assemblies on the blowout side and the rear side are provided, the present invention may be applied to a register device having one set of fin assemblies.

  The present invention is applicable to a register device for air conditioning of a vehicle.
