The thin register device shown in FIGS. 1 and 2 is installed facing a front passenger seat or a driver seat of an instrument panel (not shown) of a vehicle, and includes a register body 10. The register body 10 has a cylindrical shape and extends in the front-rear direction of the vehicle, and the upstream end thereof is connected to an air conditioner (not shown) via a duct.

The register body 10 has a flat shape in which the vertical dimension (first direction) is smaller than the horizontal dimension (second direction). The cross-sectional shape of the register main body 10 is rectangular, and has left and right side walls 11 (sub-walls), an upper wall 13 (main wall), and a lower wall 14 (main wall).
As shown in FIG. 4, the internal space of the register main body 10 is provided as the ventilation path 20, and air from the air conditioner is supplied to the vehicle compartment through the ventilation path 20.

  As shown in FIG. 4, the upper wall 13 and the lower wall 14 of the main register body 10 have special shapes, and in the order from the upstream side to the downstream side, the upstream portion 13a, 14a, the bulging portion 13b, 14b, neck portions 13c and 14c, and blowing guide portions 13d and 14d.

The upstream portions 13 a and 14 a of the upper wall 13 and the lower wall 14 are parallel to each other and extend substantially horizontally along the axis of the ventilation path 20.
The neck portions 13 c and 14 c of the upper wall 13 and the lower wall 14 are parallel to each other and extend substantially horizontally along the axis of the ventilation path 20. The distance between the neck portions 13c and 14c in the vertical direction is substantially equal to the distance between the upstream portions 13a and 14a. The axial dimensions of the neck portions 13c, 14c are smaller than the axial dimensions of the upstream portions 13a, 14a and the bulging portions 13b, 14b.

The first inclined portions 13x and 14x are inclined to be separated from each other in the blowout direction, and the second inclined portions 13z and 14z are inclined to be close to each other in the blowout direction.

  The first inclined portions 13x and 14x of the bulging portions 13b and 14b correspond to the thickness of the back side mode switching louver 41 described later from the downstream end of the upstream portions 13a and 14a and the upstream end of the parallel portions 13y and 14y. Only receding outside. Similarly, the blowout guide portions 13d, 14d are retracted outward from the downstream end of the neck portions 13c, 14c by an amount corresponding to the thickness of the blowout side mode switching louver 42 described later.

Part 23 and the outlet part 24 between the said blowing guide parts 13d and 14d.

In the upstream space portion 21, the circulation cross-sectional area is constant along the axial direction of the ventilation passage 20.
The flow cross section of the expansion space 22 is larger than the upstream space 21. More specifically, the flow cross-sectional area increases in the vertical direction in the upstream portion (between the first inclined portions 13x and 14x on the upstream side) in the blowing direction, and the downstream portion (between the second inclined portions 13z and 14z on the downstream side). The flow cross-sectional area decreases in the vertical direction and approaches the flow cross-sectional area of the reduction space 23.
The flow cross-sectional area of the reduced space portion 23 is substantially equal to that of the upstream space portion 21.
At the outlet portion 24, the flow cross-sectional area increases in the vertical direction in the blow-off direction.

  As schematically shown in FIG. 4, a wind direction adjusting mechanism 30 is disposed in the ventilation path 20. The wind direction adjusting mechanism 30 includes a blowout side fin 31 (sub fin) disposed at the central portion in the vertical direction of the blowout portion 24 of the air passage 20 and a downstream side portion of the expansion space 22 of the air passage 20. A plurality of, for example, nine back fins 32 (main fins) are arranged.

The blow-off side fins 31 have an elongated plate shape extending in the left-right direction, and both ends on the upstream side are rotatably supported by the left and right side walls 11.
As shown in FIGS. 1 and 2, an operation knob 35 is attached to the blowing fin 31. The blowing direction can be adjusted up and down by holding the operation knob 35 and turning the blowout side fins 31 around the pivot axis L1 extending in the left and right direction. The operation knob 35 is slidable in the left and right direction.

  As shown in FIG. 3 and FIG. 4, the plurality of back side fins 32 have a plate shape extending in the vertical direction, and are arranged at intervals in the horizontal direction. The plurality of back side fins 32 are rotatably supported by the upper wall 13 and the lower wall 14 via shaft portions 32 a formed at both upstream ends thereof.

  A connecting shaft portion 32b is formed on the upstream side of a middle portion in the vertical direction of the plurality of back side fins 32, and the connection shaft portions 32b of these back side fins 32 are interlocking links 33 (see FIG. 4). The plurality of back side fins 32 are interlocked with each other so as to be rotatably connected to the reference).

  An engaging member (not shown) protruding toward the back is supported by the operation knob 35 so as to be swingable in the vertical direction, and this engaging member engages with the back side fin 32 at the center in the horizontal direction. It is done. Specifically, as shown in FIG. 3, an engagement rod portion 32 c extending in the vertical direction is formed on the downstream side of the central deep fin 32, and the engagement rod 32 c engages with the operation knob 35. The bifurcated portion of the member is engaged. When the operation knob 35 is slid in the left-right direction along the blow-out fins 31, the plurality of back-side fins 32 rotate around the rotation axis L2 extending in the vertical direction, thereby adjusting the blowing direction to the left and right. be able to.

  As shown in FIG. 3 and FIG. 4, a V-shaped air blowing guide portion 34 is provided in a protruding manner on the left and right surfaces in the vertical direction central portion of all the back side fins 32 except the center back side fins 32. ing. The upper and lower guide surfaces 34a and 34b of the air blowing guide portion 34 intersect on the upstream side, and are inclined such that the distance between them gradually increases in the blow-off direction. That is, the upper guide surface 34a is inclined so as to approach the neck portion 13c of the upper wall 13 in the blowing direction, and the lower guide surface 34b is approached to the neck portion 14c of the lower wall 14 in the blowing direction. It is inclined.

The downstream ends of the guide surfaces 34 a and 34 b of the air blowing guide portion 34 of the back side fin 32 substantially coincide in axial direction with the downstream ends of the second inclined portions 13 z and 14 z of the upper wall 13 and the lower wall 14. Therefore, in the downstream portion of the expansion space portion 22 of the ventilation path 20, the flow cross-sectional area rapidly decreases toward the reduction space portion 23.
The distance between the air blowing guide portions 34 of the back side fins 32 is set so that the air blowing guide portions 34 do not interfere with each other in the rotation range of the back side fins 32.

  In the present embodiment, it is possible to selectively execute the diffusion blowing mode, the spot blowing mode, and the blowing stop by the mode switching structure. The mode switching structure includes a pair of back side mode switching louvers 41 and a pair of outlet side mode switching louvers 42.

  The pair of back side mode switching louvers 41 has a plate shape extending in the left and right direction, and is disposed in the vicinity of the first inclined portions 13 x and 14 x of the upper wall 13 and the lower wall 14 at the upstream side portion of the expansion space 22. ing. More specifically, both ends on the upstream side of the pair of back-side mode switching louvers 41 are arranged in the vicinity of the left and right sides around the rotation axis L3 extending in the left-right direction in the vicinity of the upstream ends of the first inclined portions 13x and 14x, respectively. The side wall 11 is rotatably supported.

  The pair of blowout side mode switching louvers 42 has a plate shape extending in the left-right direction, and is disposed in the blowout port portion 24 in the vicinity of the blowout guide portions 13d and 14d of the upper wall 13 and the lower wall 14, respectively. More specifically, the upstream side ends of the pair of outlet side mode switching louvers 42 are arranged on the left and right side walls around the rotation axis L4 extending in the left and right direction in the vicinity of the upstream ends of the outlet guide portions 13d and 14d, respectively. 11 is rotatably supported.

  The postures of the louvers 41 and 42 are controlled by a louver operating mechanism 50 to be described later, and it is possible to selectively execute the diffusion air blowing mode shown in FIG. 4, the spot air blowing mode shown in FIG.

  In the state where the diffusion blowing mode shown in FIG. 4 is being executed, the pair of back side mode switching louvers 41 are inclined so as to spread toward each other in the blowout direction, and the first inclined portions 13x of the upper wall 13 and the lower wall 14 It is arranged along 14x. The pair of blowout side mode switching louvers 42 are also inclined so as to spread toward each other in the blowout direction, and are arranged along the blowout guide portions 13d and 14d.

  In the diffuse air blowing mode execution state, the air that has passed through the upstream space portion 21 of the ventilation path 20 stays at the expansion space portion 22 while reducing the flow velocity, and then passes through the reduction space portion 23 while increasing the flow velocity. Head to department 24. Thus, since the air once retained in the expansion space portion 22 is blown out vigorously, a flow along the wall surfaces (more specifically, the blowing side mode switching louver 42) of the pair of blowing guide portions 13d occurs (co-under effect). As a result, air can be blown out in a wide angle range in the vertical direction.

  As described above, the flow cross-sectional area decreases in the blowing direction in the downstream portion of the expansion space portion 22, and further flows by the guide surfaces 34 a and 34 b of the air blowing guide portion 34 formed on both the left and right sides of the back fin 32. Because the cross-sectional area is reduced, the flow velocity of the air is rapidly increased, and a part of the air is divided up and down by the guide surfaces 34 a and 34 b toward the upper wall 13 and the lower wall 14, so that a very high corunder It can be effective. Therefore, the air flow can be reliably blown out along the wall surfaces (more specifically, the blowout side mode switching louver 42) of the pair of blowout guides 13d.

  In the state in which the spot air blowing mode shown in FIG. 5 is being executed, the pair of back side mode switching louvers 41 are parallel to each other and are in a posture along the axial direction of the ventilation path 20, and the pair of blowing side mode switching louvers 42 are also The postures are parallel to each other and along the axial direction of the ventilation path 20. Air from the upstream space portion 21 is regulated by the pair of back side mode switching louvers 41, so that it does not spread in the expansion space portion 22 but reaches the reduction space portion 23, and is further guided by the blowing side mode switching louver 42 and does not spread. It is blown out to the cabin in a narrow range.

  Also in the spot air blowing mode, the flow cross-sectional area is reduced by the guide surfaces 34a and 34b of the air blowing guide portion 34 of the back side fin 32, the air flow velocity increases, and part of the air is upward due to the guide surfaces 34a and 34b By going to the wall 13 and the lower wall 14, a high corunder effect can be exhibited. Therefore, the air flow can be blown out along the blowout side mode switching louver 42, and a good spot air flow can be realized.

  The stop of the air flow is realized by the pair of back side mode switching louvers 41 being in a posture orthogonal to the axial direction of the air flow passage 20, the tip edges of the two are almost in contact, and the air flow passage 20 is blocked. In the present embodiment, in the air supply stop state, the blowout side mode switching louvers 42 are parallel to each other as in the spot air supply mode.

Next, a specific example of the louver operating mechanism 50 will be described with reference to FIGS.
The louver operation mechanism 50 is disposed outside one of the left side walls 11, for example, and includes an operation dial 51 (operation member) and a linkage unit 52 that links the operation dial 51 and the mode switching louvers 41 and 42. ing.
The operation dial 51 is rotatably supported on the outside surface of the outlet side end of the left side wall 11, and a portion thereof protrudes from the instrument panel to the vehicle compartment side.
The linkage means 52 includes a first slider 53, a second slider 54, a connection link 55, a pair of first pivot links 56, and a pair of second pivot links 57.

A pair of slits 53a extending in the axial direction of the ventilation path 20 are formed at the upper and lower portions of the first slider 53, and a pair of slits 54a extending in the axial direction of the ventilation path 20 are also formed at the upper and lower portions of the second slider 54. Has been. The slit 54a is shorter than the slit 53a.
As shown in FIG. 7, on the side wall 11 of the register body 10, a pair of engaging projections 11a separated vertically are formed, and these engaging projections 11a are inserted into the slits 53a and 54a of the sliders 53 and 54. Thus, the sliders 53 and 54 are supported so as to be slidable in the axial direction of the ventilation path 20.

  The first slider 53 also has a slit 53b parallel to the slit 53a at the center in the vertical direction. As shown in FIG. 7, the first slider 53 can slide more stably by inserting another engagement projection 11 b of the side wall 11 into the slit 53 b. The slit 53b has substantially the same length as the slit 53a.

  The connecting link 55 has projections (not shown) at its both ends, and one of the projections is rotatably fitted in the engagement hole 51a (see FIG. 6) of the operation dial 51, and the other projection is the first slider 53. The engagement hole 53c (see FIG. 6) is rotatably fitted. Thus, when the operation dial 51 is turned, the first slider 53 slides in the axial direction of the air passage 20 via the connection link 55.

The first slider 53 and the second slider 54 overlap in part. As shown in FIG. 7, the first slider 53 is formed with a pair of engaging convex portions 53 d which are vertically separated, and the second slider 54 is formed with a pair of engaging concave portions 54 d which are vertically separated. Yes. When the engaging convex portion 53d and the engaging concave portion 54d are fitted, both the sliders 53 and 54 are connected, and when the first slider 53 slides as the operation dial 51 is operated, the second slider 54 is moved together in the same direction. It is supposed to slide. An engagement means K is configured by the engagement convex portion 53 d and the engagement concave portion 54 d.
The engagement convex portion 53 d and the engagement concave portion 54 d are configured to be released from the engagement state when a predetermined force or more is applied in the axial direction of the air passage 20 as described later.

As shown in FIG. 6, the first slider 53 is formed with a pair of first cam grooves 53m that are separated from each other in the vertical direction. These first cam grooves 53m have inclined portions 53x that approach each other in the blowing direction, parallel portions 53y that are parallel to each other, and inclined portions 53z that are separated from each other in the blowing direction, and are substantially U-shaped. ing.
The second slider 54 has a pair of second cam grooves 54m that are vertically separated from each other at the end on the blowing side. The second cam grooves 54m are inclined away from each other in the blow-off direction.

  The first pivoting link 56 is connected to the left end of the back mode switching louver 41 so as not to be relatively pivotable, and has a follower projection 56 a at a position away from the pivot axis of the louver 41. The follower protrusion 56 a is inserted into the first cam groove 53 m of the first slider 53.

  The second pivoting link 57 is connected to the left end of the blowout side mode switching louver 42 so as to be relatively unrotatable, and has a follower projection 57a at a position away from the pivoting axis of the louver 42. The follower protrusion 57a is inserted into the second cam groove 54m of the second slider 54.

Next, attitude control of the mode switching louvers 41 and 42 by the louver operating mechanism 50 will be described with reference to FIGS.
When the diffusion blowing mode shown in FIG. 7 is performed, the first slider 53 and the second slider 54 are connected by the engagement means K, and are located closest to the operation dial 51. The protrusion 11 a of the side wall 11 is located at the back end of the slits 53 a and 54 a of the first slider 53 and the second slider 54. Similarly, the protrusion 11b is also located at the back end of the slit 53b. Further, the follower protrusion 56 a of the first rotation link 56 is located at the back end of the inclined portion 53 x of the first cam groove 53 m of the first slider 53, and the follower protrusion 57 a of the second rotation link 57 is the second slider 54. It is located at the back end of the second cam groove 54m.

  In the state shown in FIG. 7, when the operation dial 51 is turned counterclockwise, the spot air blowing mode execution state shown in FIG. 8 is established. More specifically, the first slider 53 advances to the back through the connecting link 55, and the second slider 54 also moves together with the first slider 53 via the engagement means K. In this process, the follower protrusion 56a of the first rotation link 56 moves along the inclined portion 53x of the first cam groove 53m, and reaches the intersection between the inclined portion 53x and the parallel portion 53y. By the cam action of the follower projection 56a and the inclined portion 53x of the first cam groove 53m, the first pivoting link 56 is pivoted, and the back side mode switching louver 41 is in the parallel posture. Further, the follower projection 57a of the second rotation link 57 moves along the second cam groove 54m and reaches the end on the outlet side. By the cam action of the follower projection 57a and the second cam groove 54m, the second rotation link 57 is rotated, and the blowout side mode switching louver 42 is in the parallel posture.

  The operation dial 51 moves from a rotation position (diffuse air blowing mode execution position) where the mode switching louvers 41, 42 are inclined to a rotation position (spot air blowing mode execution position) where the mode switching louvers 41, 42 are parallel. The rotation operation range is referred to as a first operation range. As described above, in the first operation range, the first slider 53 and the second slider 54 slide together, and the mode switching louvers 41 and 42 rotate together.

  As shown in FIG. 8, in the state where the spot air blowing mode is being executed, the projections 11a and 11b of the side wall 11 are at an intermediate position between the slits 53a and 53b of the first slider 53. Slide is possible. However, since the protrusion 11 a of the side wall 11 reaches the end on the blowout side of the slit 54 a of the second slider 54, the second slider 54 is prohibited to slide further backward.

  In the state shown in FIG. 8, when the operation dial 51 is further turned counterclockwise, a force toward the back is applied to the first slider 53, but the second slider 54 is moved back by the locking action of the projection 11a and the slit 54a. The second pivoting link 57 is not pivoted, and the blowout side mode switching louver 42 is maintained in the parallel attitude.

  When the force acting on the engagement convex portion 53d and the engagement concave portion 54d exceeds a predetermined force, the engaged state of both is released, and the first slider 53 alone moves to the back. As shown in FIG. 9, along with the movement of the first slider 53, the follower projection 56a of the first rotation link 56 passes through the inclined portion 53z through the parallel portion 53y of the first cam groove 53m, and blows off the inclined portion 53z. Reach the end of the side. While the follower projection 56a passes through the parallel portion 53y, the first pivoting link 56 does not rotate, and the parallel state of the back mode switching louver 41 is maintained. While the follower projection 56a passes through the inclined portion 53z, the first pivoting link 56 is pivoted by the action of both cams, and the back mode switching louver 41 is pivoted until it becomes in a posture orthogonal to the ventilation path 20, The ventilation path 20 is shut off.

  Operation from the rotation position (spot air blowing mode execution position) that makes the mode switching louvers 41 and 42 parallel to the rotation position (air blowing stop execution position) that makes the back mode switching louver 41 perpendicular to the ventilation path 20 The rotation operation range of the dial 51 is referred to as a second operation range. As described above, in the second operation range, only the first slider 53 slides alone, and only the back mode switching louver 41 pivots.

  When the operation dial 51 is turned clockwise in the opposite direction to the above from the air supply stop state shown in FIG. 9, only the first slider 41 slides and returns to the spot air supply state shown in FIG. Here, the engagement convex portion 53 d and the engagement concave portion 54 d are engaged again, and the first slider 53 and the second slider 54 are connected. When the operation dial 51 is further turned clockwise, the first slider 53 and the second slider 54 slide together in the blow-out direction, and return to the diffusion air blowing mode execution state shown in FIG.

  In the first embodiment, the back mode switching louver 41 may be omitted. Further, the pair of outlet side mode switching louvers 42 may be manually rotated independently of each other. In this case, the louver switching mechanism is unnecessary. Furthermore, the bulging portions 13 b and 14 b of the upper wall 13 and the lower wall 14 and the blowout side fins 31 may be omitted.

Even in the second embodiment, the air flow is divided in the vertical direction by the guide surfaces 34a, 34b of the air blowing guide portion 34 of the back fin 32, and the flow cross-sectional area is rapidly reduced, so that a high corander effect can be exhibited. Good diffused air can be realized along the inclination of the blowing guide portions 13d and 14d of the upper wall 13 and the lower wall 14.
In the present embodiment, mode switching can not be performed, and diffusion air blowing is always performed. The bulging portions 13b and 14b of the upper wall 13 and the lower wall 14 and the blowout side fins 31 may be omitted.

The third embodiment shown in FIG. 11 is the same as the second embodiment except that the blowout guides 13d and 14d of the upper wall 13 and the lower wall 14 are parallel. Also in the third embodiment, the air flow is divided in the vertical direction by the guide surfaces 34a and 34b of the air flow guide portion 34 of the back side fin 32, and the circulation cross-sectional area is sharply reduced, thereby achieving a high corunder effect. Good spot air flow can be realized along the blowout guide portions 13d and 14d.
In the present embodiment, mode switching can not be performed, and spot air blowing is always performed. The bulging portions 13b and 14b of the upper wall 13 and the lower wall 14 and the blowout side fins 31 may be omitted.

  Although not shown, the main fin 32 in which the air guide portion 24 is provided may be disposed at the air outlet portion 24 of the air passage 20. In this case, the diffusion blowing can be performed by directing the air flow by the guide surfaces 34 a and 34 b of the air blowing guide portion 34.

The present invention is not limited to the above embodiment, and various aspects are possible.
The air guide portion may be provided to protrude only on one side of the main fin.
