JP6769275B2 - Air conditioning register - Google Patents

Description

The present invention relates to an air conditioner register that changes the direction of air conditioner air sent from an air conditioner and blown into a room by fins.

For example, the instrument panel of a vehicle incorporates an air conditioning register that blows out air conditioning air sent from an air conditioner. This air conditioning register includes a tubular retainer having a ventilation path for air conditioning air. The downstream end of the ventilation path in the flow direction of the air conditioning air constitutes an air outlet. Downstream fins are tiltably supported near the air outlet in the retainer. Upstream from the downstream fins in the retainer, the upstream fins are tiltably supported by the fin shaft.

In order to tilt the upstream fin, a transmission shaft portion extending parallel to the fin axis is provided at the downstream end of the upstream fin. A knob is attached to the downstream fin so as to be slidable in the longitudinal direction of the downstream fin. A fork that sandwiches the transmission shaft portion of the upstream fin is supported on the knob. Therefore, when the knob is slid in the longitudinal direction of the downstream fin, the fork moves in the same direction together with the knob, the transmission shaft portion is pushed by the fork, and the upstream fin is tilted with the fin shaft as a fulcrum. The air-conditioning air is blown out from the air outlet into the vehicle interior after being changed in the flow direction by the upstream fins and the downstream fins (see, for example, Patent Document 1).

Here, as the knob, a knob configured by assembling a plurality of parts has been conventionally used, but in recent years, it has become conceivable to configure the knob with a smaller number of parts. ..

16 (a), 16 (b) and 17 show an example thereof. A stopper 104 is formed on the upstream edge 102 of the downstream fin 101 having a long plate shape. The stopper 104 is for defining the movable region of the knob 106, and extends in the longitudinal direction of the downstream fin 101. The knob 106 is slidably attached to the downstream fin 101 in the longitudinal direction while surrounding the stopper 104. The knob 106 includes a first wall portion 107, a second wall portion 108, a connecting side wall portion 109, and a specific side wall portion 111. The first wall portion 107 and the second wall portion 108 sandwich the downstream fin 101 from both sides in the thickness direction (vertical direction). The connecting side wall portion 109 connects one (right) end portion of the first wall portion 107 and the second wall portion 108 in the longitudinal direction, and the downstream fin 101 is inserted through the connecting side wall portion 109. .. The specific side wall portion 111 is located between the other (left) ends in the longitudinal direction. The specific side wall portion 111 has an insertion hole 112 through which the downstream fin 101 is inserted, and is connected to the first wall portion 107.

The specific side wall portion 111 is divided into two in the insertion hole 112 in the thickness direction of the downstream fin 101. Further, the portion of the specific side wall portion 111 that comes into contact with the stopper 104 as the knob 106 slides has a separating portion 113 that is separated from the second wall portion 108 while being connected to the insertion hole 112.

Such a configuration is adopted to arrange the stopper 104 in the knob 106 when the knob 106 is assembled to the downstream fin 101. That is, at the time of this assembly, the downstream fin 101 is sequentially inserted from one (right) end 103 in the longitudinal direction thereof to the specific side wall 111 and the connecting side wall 109 of the knob 106. Then, the stopper 104 is inserted into the knob 106 from one (right) end 105 in the longitudinal direction through between the separating portion 113 of the specific side wall portion 111 and the second wall portion 108.

JP-A-2015-71383

In the conventional air conditioning register, when the knob 106 is slid in the longitudinal direction of the downstream fin 101, the position of the knob 106 with respect to the stopper 104 changes. Then, when the connecting side wall portion 109 (or the specific side wall portion 111) comes into contact with the stopper 104, further sliding of the knob 106 in the same direction is restricted.

However, as shown by the white arrows in FIG. 17, when the knob 106 is slid toward the side where the specific side wall portion 111 approaches the stopper 104, a force larger than an appropriate value may be applied to the knob 106. In this case, at least one of the specific side wall portion 111 and the second wall portion 108 is in the direction in which the distance between the separation portion 113 and the second wall portion 108 is widened, as shown by the arrow of the alternate long and short dash line in FIG. Elastically deforms. If the distance becomes larger than the size of the stopper 104 in the thickness direction of the downstream fin 101, the stopper 104 may pass between the separation portion 113 and the second wall portion 108 and come out of the knob 106.

The present invention has been made in view of such circumstances, and an object of the present invention is to allow a stopper to pass between a specific side wall portion and a second wall portion and escape to the outside of the knob as the knob is slid. The purpose is to provide a register for air conditioning that can suppress the above.

The air conditioning register that solves the above problems includes a long plate-shaped fin that changes the flow direction of air conditioning air, a stopper formed on the fin, and a state that surrounds the stopper in the longitudinal direction with respect to the fin. The knob includes a knob that is slidably attached to the first wall portion and the second wall portion that sandwich the fin from both sides in the thickness direction, and the longitudinal length of the first wall portion and the second wall portion. A pair of side wall portions located between one end portion and the other end portion in the direction and at least one of which is composed of a specific side wall portion are provided, and both side wall portions are insertion holes through which the fins are inserted. And connected to the first wall portion, the specific side wall portion is divided into two in the thickness direction at the insertion hole, and the specific side wall portion is attached to the stopper as the knob slides. The contacting portion has a separating portion separated from the second wall portion in a state of being connected to the insertion hole, and one of the stopper and the specific side wall portion has a convex portion protruding toward the other. In addition to being provided, a concave portion is provided at a position facing the convex portion on the other side, and at least one of the convex portion and the concave portion is specified as the convex portion enters the concave portion as the knob slides. An inclined surface that is inclined with respect to the longitudinal direction is formed so as to generate a force toward the second wall portion with respect to the side wall portion.

According to the above configuration, the knob attached to the fin while surrounding the stopper is slid in the longitudinal direction of the fin. The movable area when the knob slides is defined by the contact of both side walls with the stopper.

When the knob at the intermediate position of the movable region is slid toward the side where the specific side wall portion approaches the stopper, the convex portion enters the concave portion. At this time, an inclined surface formed on at least one of the convex portion and the concave portion and inclined with respect to the longitudinal direction of the fin comes into contact with the other of the convex portion and the concave portion. Then, as the convex portion enters the concave portion, a force is generated on the specific side wall portion toward the second wall portion, and the specific side wall portion approaches the second wall portion. Therefore, when the knob is slid toward the side where the specific side wall portion approaches the stopper, even if a force larger than the appropriate value is applied to the knob, at least one of the specific side wall portion and the second wall portion widens the distance between them. Elastic deformation in the direction is suppressed. Along with this, it is less likely that the interval becomes larger than the size of the stopper in the thickness direction of the fin. As a result, the phenomenon that the stopper passes between the specific side wall portion and the second wall portion and escapes to the outside of the knob is suppressed.

In the air conditioning register, it is preferable that the separation portion of the specific side wall portion is separated from the second wall portion via a gap portion.
As described above, when the separated portion of the specific side wall portion is separated from the second wall portion via the gap portion, the second wall portion and the specific side wall portion are separated from each other as compared with the case where they are not separated. The gap between the knob and the knob is wide, and the stopper tends to pass between the specific side wall portion and the second wall portion and come out of the knob.

However, as the convex portion enters the concave portion as described above, a force toward the second wall portion is generated in the specific side wall portion, and the specific side wall portion approaches the second wall portion, so that the stopper becomes the specific side wall portion and the second wall portion. The phenomenon of coming out of the knob through the space between the two walls is effectively suppressed.

On the other hand, when assembling the knob to the fin, the fin is inserted into the insertion hole of each side wall portion. In this state, the knob is slid toward the stopper. If the slide is continued even after the specific side wall portion hits the stopper, the stopper passes between the second wall portion and the separation portion of the specific side wall portion and enters the knob. At this time, since there is a gap portion, the stopper can easily pass between the specific side wall portion and the second wall portion.

In the air conditioning register, only one of the side wall portions is composed of the specific side wall portion, and the other is composed of the connecting side wall portion connecting the first wall portion and the second wall portion. It is preferable that the separated portion of the specific side wall portion is in contact with or close to the second wall portion.

According to the above configuration, even if the second wall portion tries to deform to the first wall portion side with the boundary portion with the connecting side wall portion as a fulcrum, the second wall portion comes into contact with the separating portion of the specific side wall portion. Further deformation is regulated. Therefore, it is possible to prevent the distance between the first wall portion and the second wall portion from fluctuating in the longitudinal direction of the fins due to the deformation of the second wall portion.

In the air conditioning register, when the inclined surface formed on at least one of the convex portion and the concave portion is used as the first inclined surface, the separated portion of the specific side wall portion has an outer wall surface of the specific side wall portion. It is preferable that a second inclined surface that inclines with respect to the longitudinal direction is formed so as to move away from the second wall portion as it approaches.

According to the above configuration, when assembling the knob to the fin, the fin is inserted into the insertion hole of each side wall portion. In this state, the knob is slid toward the stopper. If the slide is continued even after the specific side wall portion hits the stopper, the stopper passes between the second wall portion and the separation portion of the specific side wall portion and enters the knob. The separation portion is formed with a second inclined surface that inclines with respect to the longitudinal direction of the fin so as to move away from the second wall portion as it approaches the outer wall surface of the specific side wall portion. The distance between the second inclined surface and the second wall portion is maximum on the outer wall surface of the specific side wall portion, and becomes smaller as it approaches the inner wall surface of the specific side wall portion. Therefore, the stopper is more likely to enter between the second wall portion and the separated portion of the specific side wall portion than in the case where the second inclined surface is not formed in the separated portion of the specific side wall portion.

In the air conditioning register, the stopper extends in the longitudinal direction of the fin, and the convex portion or the concave portion is provided only at one end of both ends of the stopper in the longitudinal direction. It is preferable that a third inclined surface that is inclined in the same tendency as the second inclined surface with respect to the longitudinal direction is formed at the end portion on the side that is not provided.

According to the above configuration, when assembling the knob to the fin, the knob with the fin inserted through the insertion holes on both side walls is slid toward the stopper. By this slide, the second inclined surface of the specific side wall portion comes into contact with the third inclined surface of the stopper. When the slide is continued after that, the stopper passes between the second wall portion and the separation portion of the specific side wall portion and enters the knob.

Here, the third inclined surface is inclined with respect to the longitudinal direction of the fin in the same tendency as the second inclined surface. At the end of the stopper on the formed side of the third inclined surface, the dimension of the fin in the thickness direction becomes smaller as the distance from the convex or concave portion increases. Therefore, as compared with the case where the third inclined surface is not formed, the convex portion or the end portion on the side where the concave portion is not provided is more likely to enter between the second wall portion and the separating portion of the specific side wall portion.

According to the air-conditioning register, it is possible to prevent the stopper from coming out of the knob through the specific side wall portion and the second wall portion as the knob is slid.

(First Embodiment)
Hereinafter, the first embodiment embodied in the air-conditioning register incorporated in the vehicle and used will be described with reference to FIGS. 1 to 9.

In the following description, the traveling direction (forward direction) of the vehicle will be the front, the reverse direction will be the rear, and the height direction will be the vertical direction. Further, regarding the vehicle width direction (horizontal direction), the direction is defined based on the case where the vehicle is viewed from the rear.

In the passenger compartment, an instrument panel (not shown) is provided in front of the front seats (driver's seat and passenger's seat) of the vehicle, and air conditioning registers are incorporated in the central portion, side portions, etc. in the left-right direction thereof. .. The main function of this air-conditioning register is to change the direction (wind direction) of the air-conditioning air (hot air or cold air) sent from the air conditioner and blown into the vehicle interior.

As shown in FIGS. 1 to 3, the air conditioning register includes a retainer 10, a plurality of fins, a stopper 31, ridges 41 and 42 (see FIGS. 5 and 8) for exerting an operating load, a knob 45 and a fork 65. It is provided as a basic component. Next, the configuration of each of these parts will be described.

<Retainer 10>
The retainer 10 is for connecting the air duct (not shown) of the air conditioner and the opening (not shown) provided in the instrument panel. The retainer 10 is made of a plurality of members formed of a hard resin material, and has a tubular shape with both ends open. The internal space of the retainer 10 constitutes a flow path (hereinafter referred to as "ventilation passage 11") of the air conditioning air A1 sent from the air conditioner. Here, regarding the flow direction of the air conditioning air A1, the side closer to the air conditioner is referred to as "upstream", "upstream side", etc., and the side far from the air conditioner is referred to as "downstream", "downstream side", etc. .. The downstream end of the ventilation passage 11 constitutes the air outlet 12 of the air conditioning air A1.

The ventilation passage 11 is surrounded by four walls of the retainer 10. These four wall portions are composed of a pair of vertical wall portions 13 facing each other in the left-right direction and a pair of horizontal wall portions 14 facing each other in the vertical direction.

<Fin>
The fins consist of a plurality of downstream fins and a plurality of upstream fins.
The plurality of downstream fins are arranged in the ventilation passage 11 in the vicinity of the air outlet 12 so as to be separated from each other in the vertical direction. Here, in order to distinguish a plurality of upstream fins, the one located at the central portion in the vertical direction is referred to as "downstream fin 15", and the other one is referred to as "downstream fin 21".

The fin shafts 22 project outward in the same direction from both the left and right end faces of the downstream fins 15 and 21. Each of the downstream fins 15 and 21 is supported by both the left and right vertical wall portions 13 on the left and right fin shafts 22, and can be tilted in the vertical direction with the both fin shafts 22 as fulcrums.

In each of the downstream fins 15 and 21, a connecting pin 23 extending in parallel with the fin shaft 22 is provided at a portion deviated upstream from one of the fin shafts 22 (on the right side in the first embodiment). The connecting pins 23 for each of the downstream fins 15 and 21 are connected to each other by connecting rods (not shown) extending in the substantially vertical direction. A plurality of downstream fins 15 and 21 are mechanically connected by the connecting pin 23 and the connecting rod, and the downstream fins 21 are tilted in synchronization with the downstream fins 15 so as to have the same inclination as the downstream fins 15. A link mechanism is configured.

The plurality of upstream fins are arranged upstream of the downstream fins 15 and 21 of the ventilation passage 11 in a state of being separated from each other in the left-right direction. Here, in order to distinguish a plurality of upstream fins, the one located at the central portion in the left-right direction is referred to as "upstream fin 25", and the other one is referred to as "upstream fin 28".

Fin shafts 29 project outward in the same direction from both the end faces of the upstream fins 25 and 28 in the vertical direction. The upstream fins 25 and 28 are supported by both side wall portions 14 on both the upper and lower fin shafts 29. Therefore, each of the upstream fins 25 and 28 can be tilted in the left-right direction with both fin shafts 29 as fulcrums.

Unlike the other upstream fins 28, the upstream fin 25 includes a notch 26 and a transmission shaft 27. The notch 26 is formed in the downstream portion of the upstream fin 25. The transmission shaft portion 27 extends in the vertical direction at the downstream end of the notch portion 26.

A link mechanism (not shown) is provided below the plurality of upstream fins 25 and 28. The link mechanism mechanically connects the upstream fins 25 and 28 so that the upstream fins 28 are tilted in synchronization with the upstream fins 25 so as to have the same inclination as the upstream fins 25.

In the air conditioning register, the air conditioning air A1 flows along the upstream fins 25 and 28 and the downstream fins 15 and 21 in the process of passing through the ventilation passage 11. When the upstream fins 25 and 28 are tilted in the left-right direction with the upper and lower fin shafts 29 as fulcrums, the tilts of the upstream fins 25 and 28 in the same direction are changed. When each of the downstream fins 15 and 21 is tilted in the vertical direction with the left and right fin shafts 22 as fulcrums, the inclination of the downstream fins 15 and 21 in the same direction is changed. The air-conditioning air A1 flows in the directions corresponding to the inclinations of the upstream fins 25 and 28 and the downstream fins 15 and 21, and is blown out from the outlet 12.

<Stopper 31>
As shown in FIGS. 3A and 3B, the stopper 31 is for defining the movable range related to the slide of the knob 45, is the edge portion 16 on the upstream side of the downstream fin 15, and has a longitudinal length. In the middle portion in the direction, it is integrally formed with the downstream fin 15 by a hard resin material. The stopper 31 extends in the longitudinal direction of the downstream fin 15.

<Convex 41, 42>
As shown in FIGS. 5 and 8, the ridges 41 and 42 are formed at two locations on the upper surface 18 and two locations on the lower surface 19 of the downstream fin 15. Each of the ridges 41 and 42 extends in the longitudinal direction of the downstream fin 15. The pair of upper ridges 41 are located on the upper surface 18 of the downstream fin 15 at the upstream portion and the downstream portion, and have a curved surface that bulges upward. Similarly, the pair of lower ridges 42 are located on the lower surface 19 of the downstream fin 15 at the upstream portion and the downstream portion, and have a curved surface that bulges downward. Each of the ridges 41 and 42 is located at a position corresponding to the stopper 31 in the longitudinal direction of the downstream fin 15.

The ridges 41 and 42 are in contact with the knob 45, and when the knob 45 is slid, a sliding resistance is generated between the ridges 41 and 42 and the knob 45. This sliding resistance creates a load (operating load) for sliding the knob 45. This operating load is an important factor that greatly affects the operating feel (operation feeling) when operating the knob 45.

<Knob 45>
The knob 45 is a member that is mainly operated by an occupant when changing the left and right blowing directions of the air conditioning air A1 from the air outlet 12, and is a member that surrounds the stopper 31 in the longitudinal direction to the downstream fin 15. It is mounted so that it can slide.

The knob 45 includes a first wall portion 46 and a second wall portion 47, and between one end portion of the first wall portion 46 and the second wall portion 47 and between the other ends in the longitudinal direction of the downstream fin 15. It is provided with a pair of side wall portions located on each side. The entire knob 45 is made of a hard resin material.

The first wall portion 46 is arranged above the downstream fin 15, and the second wall portion 47 is arranged below the downstream fin 15. With such an arrangement, the downstream fins 15 are sandwiched by the first wall portion 46 and the second wall portion 47 from both sides in the thickness direction (vertical direction).

One side wall portion is composed of a connecting side wall portion 51 that connects the first wall portion 46 and the second wall portion 47 to each other at one end (right end) in the longitudinal direction of the downstream fin 15. The connecting side wall portion 51 has an insertion hole 52 into which the downstream fin 15 is inserted.

The other side wall portion is a first wall portion 46 and a second wall portion 47, and is composed of a specific side wall portion 53 arranged between the other end portions (left end portions) in the longitudinal direction of the downstream fin 15. There is. The specific side wall portion 53 has an insertion hole 54 through which the downstream fin 15 is inserted, and is connected to the first wall portion 46. As shown in FIG. 4, the specific side wall portion 53 is divided into two in the insertion hole 54 in the thickness direction (vertical direction) of the downstream fin 15. The portion of the specific side wall portion 53 that comes into contact with the stopper 31 as the knob 45 slides has a separating portion 59. The separation portion 59 is separated from the second wall portion 47 in a state of being connected to the insertion hole 54.

<Fork 65>
As shown in FIG. 2, the fork 65 is a member for transmitting the sliding operation of the knob 45 to the upstream fins 25 and tilting the upstream fins 25 with both the upper and lower fin shafts 29 as fulcrums. A pair of support shafts (not shown) are provided at the downstream ends of the fork 65, and these support shafts are provided with support holes 55 provided at the upstream ends of the connecting side wall portion 51 and the specific side wall portion 53 of the knob 45. It is inserted in. The fork 65 can be tilted with both fulcrums as fulcrums. The fork 65 is provided with a pair of transmission pieces 66 extending upstream in its upstream portion, and the transmission shaft portions 27 of the upstream fin 25 are sandwiched by both transmission pieces 66 from both left and right sides.

Therefore, when the knob 45 is slid in the longitudinal direction along the downstream fin 15, the transmission shaft portion 27 is pushed by one transmission piece 66 of the fork 65, and the upstream fin 25 tilts with both the upper and lower fin shafts 29 as fulcrums. Be made to.

On the other hand, even if a force in the thickness direction (vertical direction) of the downstream fin 15 is applied to the knob 45, the force is not transmitted to the transmission shaft portion 27 and the upstream fin 25 is not tilted.
The above-mentioned matter is the basic configuration of the air-conditioning register of the first embodiment.

In the first embodiment, in addition to the above basic configuration, as shown in FIGS. 3 (a), 3 (b) and 8, the separating portion 59 of the specific side wall portion 53 passes from the second wall portion 47 via the gap portion 56. Are separated.
Further, a convex portion 33 is formed on the end portion 32 of the stopper 31 on the specific side wall portion 53 side and on the first wall portion 46 side, which projects toward the specific side wall portion 53. It should be noted that such a convex portion is not formed on the end portion 35 on the side of the connecting side wall portion 51 of the stopper 31. A recess 57 is formed in a portion of the specific side wall portion 53 facing the convex portion 33, that is, a portion on the first wall portion 46 side.

As the convex portion 33 enters the concave portion 57, the convex portion 33 is inclined with respect to the longitudinal direction of the downstream fin 15 so as to generate a force toward the second wall portion 47 side with respect to the specific side wall portion 53. An inclined surface 34 is formed. Further, the concave portion 57 is inclined with respect to the longitudinal direction of the downstream fin 15 so as to generate a force toward the second wall portion 47 with respect to the specific side wall portion 53 as the convex portion 33 enters the concave portion 57. One inclined surface 58 is formed. Each of the first inclined surfaces 34 and 58 is inclined with respect to the longitudinal direction so that the closer to the outer wall surface 62 of the specific side wall portion 53, the farther away from the second wall portion 47.

A second inclined surface 63 is formed in the separating portion 59 of the specific side wall portion 53. The second inclined surface 63 is inclined with respect to the longitudinal direction of the downstream fin 15 so that the closer to the outer wall surface 62 of the specific side wall portion 53, the farther away from the second wall portion 47.

Of the ends 32 and 35 of the stopper 31 in the longitudinal direction of the downstream fin 15, the end 35 on the side (right side) where the convex portion 33 is not provided, and the portion on the first wall portion 46 side is the same. A third inclined surface 36 is formed which is inclined in the same tendency as the second inclined surface 63 with respect to the longitudinal direction.

In addition to this, in the second wall portion 47, the portion facing the second inclined surface 63 is located in the longitudinal direction so as to move away from the specific side wall portion 53 as it approaches the outer wall surface 62 of the specific side wall portion 53. A fourth inclined surface 48 that inclines to the side opposite to the second inclined surface 63 is formed.

Next, the actions and effects of the first embodiment configured as described above will be described separately for each situation.
<When molding the knob 45>
A mold 75 (see the alternate long and short dash line in FIG. 4) is used for forming the knob 45. The mold 75 has a cavity 71 for forming a knob. The mold 75 has a common gate 72 and a pair of branch gates 73, 74 branched from the common gate 72 and connected to the cavity 71 as a portion (gate) to be an inlet (gate) of the resin material R in a molten state into the cavity 71. Have.

Then, at the time of molding the knob 45 using the mold 75, the molten resin material R that has passed through the common gate 72 is divided into both branch gates 73 and 74 and flows. The resin material R separated from the common gate 72 and flowing into the branch gate 73 is supplied to the portion 71a in the cavity 71 where the first wall portion 46 is formed. The resin material R separated from the common gate 72 and flowing into the branch gate 74 is supplied to the portion 71b in the cavity 71 where the second wall portion 47 is formed.

By cooling and curing the resin material R filled in the cavity 71, a knob 45 having a first wall portion 46, a second wall portion 47, a connecting side wall portion 51, and a specific side wall portion 53 is formed. Further, at this time, the resin material R in the common gate 72 and both the branch gates 73 and 74 is cooled and cured in a state of bridging the first wall portion 46 and the second wall portion 47, and the first wall portion thereof is cooled and cured. It is restricted that the 46 and the second wall portion 47 are formed in a deformed state. Therefore, the first wall portion 46 and the second wall portion 47 can be formed into a desired shape, and the dimensions of the knob 45 can be stabilized.

The knob 45 is formed by cooling and curing the resin material R in the cavity 71. The resin material R cooled and cured in the common gate 72 and both branch gates 73 and 74 is formed in the knob 45. Remains connected. Therefore, this excess resin material R is cut off after molding the knob 45.

<When assembling the knob 45 to the downstream fin 15>
As shown in FIGS. 3A and 5, when the knob 45 is assembled to the downstream fin 15 while surrounding the stopper 31, the convex portion 33 of the stopper 31 is in the longitudinal direction of the downstream fin 15. The downstream fin 15 is inserted into the insertion hole 54 of the specific side wall portion 53 and also through the insertion hole 52 of the connecting side wall portion 51 from the end portion 20 on the same side as the side on which the is not provided. In this state, as shown in FIGS. 6A and 6B, the knob 45 is slid toward the stopper 31.

As shown by the white arrows in FIG. 7, when the slide is continued even after the specific side wall portion 53 hits the end portion 35 on the side where the convex portion 33 of the stopper 31 is not provided, the end portion 35 However, it enters the knob 45 through the gap portion 56 between the second wall portion 47 and the separation portion 59 of the specific side wall portion 53.

At this time, the stopper 31 is a separating portion 59 and passes through the second inclined surface 63 formed in the region from the inner wall surface 61 to the outer wall surface 62 of the specific side wall portion 53. The second inclined surface 63 is inclined with respect to the longitudinal direction of the downstream fin 15 so that the closer to the outer wall surface 62, the farther away from the second wall portion 47. Moreover, in the second wall portion 47, the fourth inclined surface 48 formed at a portion facing the second inclined surface 63 is directed from the specific side wall portion 53 as it approaches the outer wall surface 62 with respect to the longitudinal direction. , It is inclined to the side opposite to the second inclined surface 63. The distance between the second inclined surface 63 and the fourth inclined surface 48 is maximum on the outer wall surface 62. Therefore, the end portion 35 of the stopper 31 is more likely to enter between the separation portion 59 and the second wall portion 47 than in the case where at least one of the second inclined surface 63 and the fourth inclined surface 48 is not formed.

Further, the third inclined surface 36 of the stopper 31 is inclined with respect to the longitudinal direction of the downstream fin 15 in the same tendency as the second inclined surface 63. Due to the third inclined surface 36, the dimension of the end portion 35 of the stopper 31 in the thickness direction of the downstream fin 15 becomes smaller as the distance from the convex portion 33 increases. Therefore, as compared with the case where the third inclined surface 36 is not formed, the end portion 35 of the stopper 31 is more likely to enter between the separation portion 59 and the second wall portion 47.

Further, the fact that the gap portion 56 is set between the separation portion 59 and the second wall portion 47 also facilitates the passage through the stopper 31.
By the above slide, the second inclined surface 63 of the specific side wall portion 53 comes into contact with the third inclined surface 36 of the end portion 35 of the stopper 31, and the fourth inclined surface 48 comes into contact with the lower surface 37 of the stopper 31. When the above slide is continued after that, the stopper 31 enters the knob 45 through the gap 56. When the entire stopper 31 enters the knob 45 and is surrounded by the knob 45, the knob 45 is in a state of being assembled to the downstream fin 15.

<When sliding the knob 45>
When changing the left and right blowing directions of the air conditioning air A1, the knob 45 in FIG. 8 is slid in the longitudinal direction of the downstream fin 15. The movable region when the knob 45 slides is defined by the connecting side wall 51 coming into contact with the end 35 of the stopper 31 and the specific side wall 53 coming into contact with the end 32 of the stopper 31.

During this slide operation, the first wall portion 46 of the knob 45 slides against the pair of ridges 41 formed on the upper surface 18 of the downstream fin 15. Similarly, the second wall portion 47 of the knob 45 slides against the pair of ridges 42 formed on the lower surface 19 of the downstream fin 15. The load when sliding the knob 45 due to the sliding resistance generated between the first wall portion 46 and the double ridges 41 and the sliding resistance generated between the second wall portion 47 and the double ridges 42 ( Operating load) is created.

Here, the portion of the specific side wall portion 53 that comes into contact with the end portion 32 of the stopper 31 as the knob 45 slides has a separating portion 59. The separation portion 59 is separated from the second wall portion 47 in a state of being connected to the insertion hole 54. Therefore, when a force larger than an appropriate value is applied to the knob 45 when sliding the knob 45, at least one of the specific side wall portion 53 and the second wall portion 47 is elastically deformed in a direction in which the distance between them is widened. To do. When the interval becomes larger than the size of the stopper 31 in the thickness direction of the downstream fin 15, the stopper 31 passes between the separation portion 59 of the specific side wall portion 53 and the second wall portion 47 and escapes to the outside of the knob 45. There is a risk.

In particular, when the separation portion 59 is separated from the second wall portion 47 via the gap portion 56 as in the first embodiment, the stopper 31 is outside the knob 45 as compared with the case where the separation portion 59 is not separated. Easy to get out.

However, in the first embodiment, as shown in FIG. 8, the knob 45 at the intermediate position of the movable region moves toward the side where the specific side wall portion 53 approaches the stopper 31, as shown by the white arrow in FIG. When slid, the convex portion 33 of the stopper 31 enters the concave portion 57 of the specific side wall portion 53. At this time, the first inclined surfaces 34 and 58, which are formed in the convex portion 33 and the concave portion 57 and are inclined with respect to the longitudinal direction of the downstream fin 15, come into contact with each other. Then, as the convex portion 33 enters the concave portion 57, a force F1 is generated on the specific side wall portion 53 toward the second wall portion 47, and the specific side wall portion 53 approaches the second wall portion 47.

Therefore, even if a force larger than the appropriate value is applied to the knob 45 as described above, at least one of the specific side wall portion 53 and the second wall portion 47 is suppressed from being elastically deformed in the direction in which the distance between them is widened. To. Along with this, it is less likely that the interval becomes larger than the size of the stopper 31 in the thickness direction of the downstream fin 15. As a result, it is possible to prevent the stopper 31 from coming out of the knob 45 through between the specific side wall portion 53 and the second wall portion 47.

(Second Embodiment)
Next, a second embodiment of the air conditioning register will be described with reference to FIGS. 10 to 14.
In the second embodiment, as shown in FIGS. 11 (a), 11 (b) and 12, in the state before the knob 45 is assembled to the downstream fin 15 and before surrounding the stopper 31, the specific side wall portion 53 The separation portion 59 is connected to the second wall portion 47.

Further, as shown in FIGS. 10A, 10B and 13, when the knob 45 is assembled to the downstream fin 15 and surrounds the stopper 31, the separating portion 59 of the specific side wall portion 53 is the second wall portion. It is separated from 47 and is in contact with or close to the second wall portion 47.

The second inclined surface 63 formed in the separation portion 59 is larger than the first embodiment with respect to the longitudinal direction of the downstream fin 15 so that the closer to the outer wall surface 62 of the specific side wall portion 53, the farther away from the second wall portion 47. It is tilted at an angle.

The configuration other than the above is the same as that of the first embodiment. Therefore, the same elements as those described in the first embodiment are designated by the same reference numerals, and duplicate description will be omitted.
Therefore, according to the second embodiment, the same actions and effects as those of the first embodiment can be obtained. In addition, according to the second embodiment, the following actions and effects can be obtained.

<When molding the knob 45>
The knob 45 in a state where the separating portion 59 of the specific side wall portion 53 is connected to the second wall portion 47 is formed by resin molding. The molten resin material is supplied to the cavity through the gate. The resin material filled in the cavity is cooled and cured to form the first wall portion 46, the second wall portion 47, and the connecting side wall portion 51. Further, a specific side wall portion 53 in a state where the separation portion 59 is connected to the second wall portion 47 is formed.

In this way, since the separating portion 59 of the specific side wall portion 53 is connected to the second wall portion 47, it is possible to prevent the first wall portion 46 and the second wall portion 47 from being molded in a deformed state. The first wall portion 46 and the second wall portion 47 of the above can be formed into a desired shape to stabilize the dimensions of the knob 45.

<When assembling the knob 45 to the downstream fin 15>
As shown in FIG. 12, when the knob 45 is assembled to the downstream fin 15, the end portion 20 (in the longitudinal direction of the downstream fin 15 and on the same side as the side on which the convex portion 33 of the stopper 31 is not provided) ( From FIG. 3A), the downstream fin 15 is inserted into the insertion hole 54 of the specific side wall portion 53 and also through the insertion hole 52 of the connecting side wall portion 51. In this state, the knob 45 is slid toward the stopper 31 as shown by the white arrow in FIG.

If the slide is continued even after the specific side wall portion 53 hits the end portion 35 of the stopper 31, the stopper 31 breaks the connecting portion between the separation portion 59 of the specific side wall portion 53 and the second wall portion 47. By this break, the separating portion 59 is separated from the second wall portion 47. After that, as shown in FIG. 13, the stopper 31 passes between the second wall portion 47 and the separating portion 59 and enters the knob 45 as in the first embodiment.

In the second embodiment as well, the second inclined surface 63 is formed in the separation portion 59 as in the first embodiment. Further, in the second wall portion 47, a fourth inclined surface 48 is formed at a position facing the second inclined surface 63. The distance between the second inclined surface 63 and the fourth inclined surface 48 is maximum on the outer wall surface 62 of the specific side wall portion 53. Therefore, the stopper 31 is more likely to enter between the second wall portion 47 and the separation portion 59 than in the case where at least one of the second inclined surface 63 and the fourth inclined surface 48 is not formed.

Further, a third inclined surface 36 is formed at the end portion 35 of the stopper 31, and the dimension of the downstream fin 15 in the thickness direction of the end portion 35 becomes smaller as the distance from the convex portion 33 increases. Also in this respect, the end portion 35 of the stopper 31 is more likely to enter between the second wall portion 47 and the separation portion 59 than in the case where the third inclined surface 36 is not formed.

<When sliding the knob 45>
Here, FIG. 14 shows a comparative example in which the separating portion 59 of the specific side wall portion 53 is separated from the second wall portion 47 via the gap portion 56. In this comparative example, the second wall portion 47 may be deformed toward the side closer to the first wall portion 46 with the boundary portion with the connecting side wall portion 51 as a fulcrum. When this deformation occurs, the distance between the first wall portion 46 and the second wall portion 47 becomes large near the connecting side wall portion 51 and decreases as it approaches the specific side wall portion 53. When the distance near the connecting side wall portion 51 is represented by D1, the distance between the downstream fins 15 in the intermediate portion in the longitudinal direction is represented by D2, and the distance near the specific side wall portion 53 is represented by D3, the spacing D1 and D2 , D3 has a relationship of D1>D2> D3. In this way, the distance between the first wall portion 46 and the second wall portion 47 varies in the longitudinal direction of the downstream fin 15. Along with this, the sliding resistance generated between the first wall portion 46 and the second wall portion 47 of the knob 45 and the ridges 41 and 42 is small in the wide space and large in the narrow space. In this way, the sliding resistance varies in the longitudinal direction of the downstream fin 15.

On the other hand, in the second embodiment, as shown in FIG. 13, even if the second wall portion 47 tries to deform toward the first wall portion 46 side with the boundary portion with the connecting side wall portion 51 as a fulcrum, the second wall portion 47 When 47 comes into contact with the separating portion 59 of the specific side wall portion 53, further deformation is restricted. Therefore, the distance between the first wall portion 46 and the second wall portion 47 is substantially uniform at any position of the knob 45 in the longitudinal direction of the downstream fin 15. Therefore, regardless of where the stopper 31 is located in the knob 45, that is, whether it is located at the location indicated by the solid line in FIG. 13 or at the location indicated by the alternate long and short dash line, the ridge 41 The sliding resistance generated between the and 42 is substantially uniform. Therefore, it is possible to suppress the sliding resistance from fluctuating in the longitudinal direction of the downstream fin 15, and to improve the operation feeling (operation feeling) when operating the knob 45.

It should be noted that each of the above embodiments can also be implemented as a modified example in which this is modified as follows.
<About stopper 31>

In this case, the specific side wall portion 53 of the knob 45 is located on the upstream side and the downstream side of the downstream fin 15 and connected to the insertion hole 54, in a portion that comes into contact with the stopper 31 as the knob 45 slides. It is separated from the second wall portion 47.

<About inclined surfaces>

An example of modification formed parallel to the longitudinal direction of 15 is shown.

In any of the above modifications, by sliding the knob 45 in the direction indicated by the white arrow, the force F1 toward the second wall portion 47 is applied to the specific side wall portion 53 as the convex portion 33 enters the concave portion 57. It can be generated, and the same actions and effects as those of the first embodiment can be obtained.

-At least one of the second inclined surface 63, the third inclined surface 36, and the fourth inclined surface 48 may be omitted.

An inclined surface that is inclined with respect to the longitudinal direction of the fin 15 is formed.

<About the side wall>
-Both side wall portions in each of the above embodiments may be configured by a specific side wall portion.
