Description

The present invention relates to an air conditioning register.

Vehicles such as automobiles are equipped with an air conditioner and an air conditioner register. The air conditioning air flowing from the air conditioner is blown into the vehicle interior through the air conditioning register. The air-conditioning register is for adjusting the blowing direction of the air-conditioning air.

The air-conditioning register has downstream fins and upstream fins provided in the ventilation passage through which the air-conditioning air flows. The downstream fin is formed in the shape of a long plate and is rotatable around the center line of the first rotation axis. Further, the upstream fin is located on the upstream side of the downstream fin in the ventilation path. The upstream fin is made rotatable around the center line of the second rotation axis. The second rotation axis extends in a direction different from that of the first rotation axis.

As shown in Patent Document 1, a knob operated by a user is attached to the downstream fin. This knob is used to operate the downstream fins and the upstream fins.
The downstream fins are provided with a penetration that penetrates the knob. A protrusion protruding toward the knob is integrally formed in this penetrating portion. The knob can be moved in the direction of the long side of the downstream fin. The user can rotate the downstream fin around the center line of the first rotation axis by pinching the knob by hand. The user can also rotate the upstream fin around the center line of the second rotation axis by moving the knob toward the long side of the downstream fin. That is, at this time, when the knob pushes the upstream fin, the upstream fin rotates around the center line of the second rotation axis.

The user adjusts the blowing direction of the air conditioning air into the vehicle interior by changing the rotation positions of the downstream fins and the upstream fins in the air conditioning register.

Japanese Unexamined Patent Publication No. 2018-65506

In Patent Document 1, a protrusion is integrally formed at the penetrating portion of the downstream fin. Then, since the protrusion and the knob come into contact with each other, the contact area between the penetrating portion and the knob becomes smaller. As a result, the user can operate the knob with a weak force so that the knob moves toward the long side of the downstream fin.

However, when the user moves the knob toward the long side of the downstream fin, the force of the user's hand acts to tilt the knob with respect to the downstream fin. At this time, the knob may be deformed so as to be inclined in the thickness direction of the downstream fin. When the knob is deformed in this way, a gap is created between the protrusion and the knob. In this case, when the knob moves in the long side direction of the downstream fin, the knob rattles due to the gap between the protrusion and the knob. As a result, the knob cannot be smoothly moved in the direction of the long side of the downstream fin.

An object of the present invention is to provide an air conditioning register capable of smoothly moving a knob in the long side direction of a downstream fin.

Hereinafter, means for solving the above problems and their actions and effects will be described.
The air-conditioning register that solves the above problems includes a long plate-shaped downstream fin provided in the ventilation path through which the air-conditioning air flows, an upstream fin provided on the upstream side of the downstream fin of the ventilation path, and a downstream fin. It has a knob that penetrates in the long side direction. The downstream fin can rotate around the center line of the first rotation axis. The knob is movable in the direction of the long side of the downstream fin, and the upstream fin is rotated around the center line of the second rotation axis through the movement. The downstream fin comprises a penetrating portion penetrating the knob and a protruding member attached to the penetrating portion. The projecting member is formed of an elastic material that is softer than the downstream fins, and projects from the penetrating portion in the thickness direction of the downstream fins. The amount of protrusion of the protruding member from the penetrating portion is such that when the knob is removed from the downstream fin, the width in the thickness direction of the downstream fin including the protruding member in the penetrating portion is the width in the thickness direction in the internal space of the knob. It is set to a value that is larger than.

According to the above configuration, when the knob is attached to the downstream fin, that is, when the penetrating portion of the downstream fin penetrates the knob, the protruding member assembled to the penetrating portion is pressed against the inner surface of the knob and elastically deforms. This is because the projecting member is made of an elastic material softer than the downstream fins, and the amount of projecting from the penetrating portion of the projecting member is determined as described above. Therefore, when the user moves the knob toward the long side of the downstream fin, the knob tilts in the thickness direction with respect to the downstream fin as the force of the user's hand acts to tilt the knob with respect to the downstream fin. Even when it is deformed to do so, the protruding member is held in a state of being pressed against the inner surface of the knob. Therefore, the deformation of the knob does not cause a gap between the protruding member and the knob, and the rattling of the knob due to the gap when the knob moves in the long side direction of the downstream fin can be suppressed.

In the air conditioning register, it is conceivable that the protruding member has a shape extending in the long side direction of the downstream fin.
According to this configuration, a protruding member extending in the long side direction of the downstream fin is pressed against the inner surface of the knob through which the penetrating portion of the downstream fin penetrates. Therefore, when the user moves the knob in the long side direction of the downstream fin, even if the knob is deformed so as to be inclined in the thickness direction with respect to the downstream fin, the protruding member extending as described above is from the knob. The above deformation can be suppressed by receiving a force.

In the air-conditioning register, the protruding member penetrates the penetrating portion in the thickness direction of the downstream fin. Further, a retaining portion is formed at the end of the protruding member on the opposite side of the protruding portion from the penetrating portion to prevent the protruding member from coming out of the penetrating portion in the protruding direction from the penetrating portion. There is.

When the knob is moved in the long side direction of the downstream fin, the protruding member is pulled in the direction of being pulled out from the penetrating portion by the frictional force between the protruding member and the knob. According to the above configuration, the protrusion of the protruding member from the penetrating portion is suppressed by the retaining portion formed at the end portion of the protruding member opposite to the portion protruding from the penetrating portion.

In the air-conditioning register, the protruding member penetrates the penetrating portion in the thickness direction of the downstream fin. Further, both ends of the projecting member project from the penetrating portion and have a width larger than that of the portion located in the penetrating portion.

When the knob is moved in the long side direction of the downstream fin, the protruding member is pulled in the direction of being pulled out from the penetrating portion by the frictional force between the protruding member and the knob. According to the above configuration, the protrusion of the projecting member from the penetrating portion is suppressed by both ends having a width larger than that of the projecting member located in the penetrating portion.

In the air-conditioning register, a plurality of projecting members are provided at intervals in the short side direction of the downstream fins.
According to this configuration, a plurality of projecting members spaced apart from each other in the short side direction of the downstream fin are pressed against the inner surface of the knob through which the penetrating portion of the downstream fin penetrates. Therefore, when the user moves the knob in the long side direction of the downstream fin, the knob can be supported by the plurality of projecting members. Therefore, when the knob is moved in the long side direction of the downstream fin, the knob is less likely to tilt with respect to the downstream fin, and it is possible to prevent the tilt from adversely affecting the smooth movement of the knob.

According to the present invention, the knob can be smoothly moved in the long side direction of the downstream fin.

FIG. 6 is a cross-sectional view showing another example of the penetrating portion and the protruding member.

Hereinafter, an embodiment of the air conditioning register will be described with reference to FIGS. 1 to 5.
The air-conditioning register shown in FIG. 1 includes a retainer 1, and a ventilation passage 2 passes through the inside of the retainer 1. In the air-conditioning register, the air-conditioning air passes through the ventilation passage 2 of the retainer 1 and is blown out to the passenger compartment. The air conditioning register includes a plurality of downstream fins 3 and 4, and a plurality of upstream fins 5 and 6. The downstream fins 3 and 4 and the upstream fins 5 and 6 are for changing the blowing direction of the air conditioning air in the air-conditioning register.

The downstream fins 3 and 4 are arranged in the ventilation passage 2 of the air conditioning register. The downstream fins 3 and 4 have a plate shape extending in the left-right axial direction in FIG. 1, and are arranged at intervals in the vertical axis direction in FIG. Of the plurality of downstream fins 3 and 4, the downstream fin 3 is located in the center. The downstream fins 4 are arranged on both sides of the downstream fins 4 in the vertical axis direction. The downstream fin 3 is rotatable around the center line of the rotating shaft 7 extending in the left-right axial direction in FIG. The downstream fin 4 is rotatable around the center line of the rotating shaft 8 extending in the left-right axial direction in FIG.

The rotation shaft 7 is fixed to the end of the downstream fin 3 in the long side direction. The rotating shaft 7 is supported by the retainer 1 so that it can rotate around the center line of the rotating shaft 7. Further, the rotation axis 7 is prevented from moving in the direction of the center line. The rotating shaft 7 serves as a first rotating shaft. On the other hand, the rotation shaft 8 is fixed to the end portion of the downstream fin 4 in the long side direction. The rotating shaft 8 is supported by the retainer 1 so that it can rotate around the center line of the rotating shaft 8.

The plurality of downstream fins 3 and 4 are connected to each other so as to be able to rotate synchronously. Therefore, when the downstream fin 3 is rotated around the center line of the rotation shaft 7, the rotation of the downstream fin 3 is transmitted to the downstream fin 4. As a result, the downstream fin 4 rotates around the center line of the rotation shaft 8 in the same manner as the rotation of the downstream fin 3. The connection between the downstream fin 3 and the downstream fin 4 is realized by the link 12. The link 12 is an end portion of the downstream fins 3 and 4 in the long side direction, and is arranged on the upstream side of the rotation shafts 7 and 8.

The upstream fins 5 and 6 are arranged on the upstream side of the downstream fins 3 and 4 in the ventilation passage 2. The upstream fins 5 and 6 have a plate shape extending in the vertical axis direction of FIG. 1, and are arranged at intervals in the left-right axial direction of FIG. Of the plurality of upstream fins 5 and 6, the upstream fin 5 is located in the center. The upstream fins 6 are arranged on both sides of the upstream fins 5 in the left-right axial direction. The upstream fin 5 is rotatable around the center line of the rotating shaft 13 extending in the vertical axis direction of FIG. The upstream fin 6 is rotatable around the center line of the rotating shaft 14 extending in the vertical axis direction of FIG.

The rotating shaft 13 is fixed to the end portion of the upstream fin 5 in the vertical axis direction. The rotating shaft 13 is supported by the retainer 1 so that it can rotate around the center line of the rotating shaft 13. On the other hand, the rotating shaft 14 is fixed to the end portion of the upstream fin 6 in the vertical axis direction. The rotating shaft 14 is supported by the retainer 1 so that it can rotate around the center line of the rotating shaft 14. The plurality of upstream fins 5 and 6 are connected to each other so as to be able to rotate synchronously. Therefore, when the upstream fin 5 is rotated around the center line of the rotation shaft 13, the rotation of the upstream fin 5 is transmitted to the upstream fin 6. As a result, the upstream fin 6 rotates around the center line of the rotation shaft 14 in the same manner as the rotation of the upstream fin 5.

In the air-conditioning register, by rotating the downstream fins 3 and 4, the direction in which the air-conditioning air is blown out from the ventilation passage 2 is changed to the vertical axis direction in FIG. Further, by rotating the upstream fins 5 and 6, the direction in which the air conditioning air is blown out from the ventilation passage 2 is changed to the left-right axial direction in FIG. The air conditioning register includes a knob 23 for rotating the downstream fin 3 and the upstream fin 5. By operating the knob 23, the user rotates the downstream fins 3 and 4 and rotates the upstream fins 5 and 6.

Next, the downstream fin 3 and the knob 23 will be described in detail.
As shown in FIG. 1, the downstream fin 3 penetrates the knob 23 in the left-right axial direction. The user can hold the knob 23 by hand and rotate the downstream fin 3 around the center line of the rotation shaft 7 via the knob 23. The downstream fin 3 and the downstream fin 4 rotate in synchronization with each other by the link 12. As a result, the direction in which the air conditioning air is blown out from the ventilation passage 2 changes in the vertical axis direction.

As shown in FIG. 2, the downstream fin 3 includes a penetration portion 24 that penetrates the knob 23. The knob 23 is movable in the long side direction of the downstream fin 3. The movement of the knob 23 at this time is a relative movement with respect to the downstream fin 3 (penetration portion 24). A pair of forks 20 are formed at the end of the knob 23 on the upstream side (upper side in FIG. 2). As shown in FIG. 1, the pair of forks 20 are positioned so as to sandwich the upstream fin 5 in the left-right axial direction.

As shown in FIG. 3, a space portion 18 that penetrates the upstream fin 5 in the thickness direction is formed in the downstream portion of the upstream fin 5. A connecting bar 19 extending in the vertical axis direction is provided at the downstream end of the upstream fin 5, that is, the portion on the downstream side of the space portion 18. The connecting bar 19 is sandwiched by a pair of forks 20 of the knob 23.

When the knob 23 moves in the long side direction of the downstream fin 3 (FIG. 1), the connecting bar 19 receives pressure from the knob 23 (fork 20) in the moving direction. With such pressing, the upstream fin 5 rotates around the center line of the rotation shaft 13. During rotation of the upstream fin 5, contact of the fork 20 with a portion other than the connecting bar 19 of the upstream fin 5 is prevented by the space portion 18 of the upstream fin 5.

As shown in FIG. 3, the plurality of upstream fins 5 and 6 are connected to each other by a link 15 so that they can rotate in synchronization with each other. The link 12 is located at the upper end of the upstream fins 5 and 6, and is located on the upstream side of the rotation shafts 13 and 14. The user can rotate the upstream fin 5 around the center line of the rotation shaft 13 by moving the knob 23 in the long side direction of the downstream fin 3 (FIG. 1). The upstream fin 5 and the upstream fin 6 rotate synchronously by the link 15. As a result, the direction in which the air conditioning air is blown out from the ventilation passage 2 changes in the left-right axial direction in FIG.

FIG. 4 shows a state in which the downstream fin 3 and the knob 23 are viewed from the direction of arrows AA in FIG. The knob 23 is formed with a through hole 25 for passing the downstream fin 3 (penetration portion 24). The through hole 25 extends in the long side direction of the downstream fin 3 (direction orthogonal to the paper surface of FIG. 4). The penetration portion 24 is located on the upstream side (right side in FIG. 4) in the through hole 25. On the downstream side (left side in FIG. 4) of the through hole 25, a mounting piece 26 projecting from the inner surface of the through hole 25 toward the upstream end of the through portion 24 is formed. An elastic member 27 is attached to the attachment piece 26, and the elastic member 27 is pressed against the upstream end of the penetrating portion 24.

As shown in FIG. 5, the downstream fin 3 includes a plurality of protrusions 28 integrally formed with the penetration portion 24, and a plurality of projecting members 29 assembled with the penetration portion 24.
The downstream fin 3 (penetration portion 24) is formed of, for example, a hard resin. Examples of such resins include polyethylene terephthalate (PBT-GF) containing glass fiber, polypropylene glycol (PPG), polyester-based thermoplastic elastoma (TPC), polyamide (PA), and glass fiber reinforced polyamide (PA-GF). Be done.

The projecting member 29 is made of an elastic material that is softer than the penetrating portion 24. Examples of such elastic materials include thermoplastic elastomers (TPE) such as olefin-based thermoplastic elastomers (TPO) and dynamically crosslinked thermoplastic elastomers (TPV).

A plurality of protrusions 28 are formed at intervals in the short side direction (left-right axis direction in FIG. 5) of the downstream fin 3. The protrusion 28 is located on one surface 24a in the thickness direction of the penetration portion 24. The protrusion 28 projects from the surface 24a toward the knob 23 side (lower side in FIG. 5). The protrusion 28 has a shape extending in the long side direction of the downstream fin 3 (direction orthogonal to the paper surface in FIG. 5).

A plurality of projecting members 29 are provided at intervals in the short side direction of the downstream fin 3. The projecting member 29 is located on the other surface 24b in the thickness direction of the penetrating portion 24. The projecting member 29 is positioned so as to correspond to the protrusion 28 of the surface 24a. The protruding member 29 has a shape extending in the long side direction of the downstream fin 3.

The projecting member 29 includes a main body 29a embedded in the penetrating portion 24 and an end portion 29b projecting from the surface 24b toward the knob 23 side (upper side in FIG. 5). The end portion 29b has a width larger than that of the main body 29a.

The penetrating portion 24 and the protruding member 29 of the downstream fin 3 are formed by injection molding such as insert molding or two-color molding. Therefore, when the penetrating portion 24 and the protruding member 29 are formed by injection molding, the protruding member 29 is in a state of being assembled to the penetrating portion 24.

The amount of protrusion of the protrusion member 29 from the surface 24b is determined based on the following widths X1 and X2. The width X1 is the maximum width in the thickness direction of the penetrating portion 24 when the knob 23 is removed from the downstream fin 3, and more specifically, the maximum width in the thickness direction of the penetrating portion 24 including the protrusion 28 and the protruding member 29. It is significant. The width X2 is the width of the internal space (through hole 25) of the knob 23 in the thickness direction. The amount of protrusion of the protruding member 29 from the surface 24b is determined so that the width X1 and the width X2 satisfy the relationship of the following formula "X1> X2".

Next, the operation of the air-conditioning register of the present embodiment will be described.
When the knob 23 is attached to the downstream fin 3, that is, when the penetrating portion 24 of the downstream fin 3 penetrates the through hole 25 of the knob 23, the protruding member 29 (end portion 29b) assembled to the penetrating portion 24 is the knob 23. It is pressed against the inner surface of (through hole 25) and elastically deforms. This is because the protruding member 29 is made of an elastic material softer than the downstream fin 3 (penetration portion 24), and the amount of protrusion of the protruding member 29 from the surface 24b of the penetrating portion 24 is determined as described above. Because it is.

When the user moves the knob 23 toward the long side of the downstream fin 3, the force of the user's hand acts to tilt the knob 23 with respect to the downstream fin 3. At this time, the knob 23 may be deformed so as to be inclined in the thickness direction of the downstream fin 3. Here, the projecting member 29 is pressed against the inner surface of the knob 23 (through hole 25) and elastically deformed. Therefore, even when the knob 23 is deformed as described above, the protruding member 29 is held in a state of being pressed against the inner surface of the knob 23 (through hole 25). Therefore, as described above, there is no gap between the protruding member 29 and the inner surface of the knob 23 due to the deformation of the knob 23, and the knob 23 smoothly moves in the long side direction of the downstream fin 3. The rattling of the knob 23 due to the gap can be suppressed.

According to the present embodiment described in detail above, the following effects can be obtained.
(1) When the knob 23 is moved in the long side direction of the downstream fin 3, the knob 23 can be prevented from rattling. Therefore, the knob 23 can be smoothly moved in the long side direction of the downstream fin 3.

(2) A protruding member 29 extending in the long side direction of the downstream fin 3 is pressed against the inner surface of the knob 23 (through hole 25) through which the penetrating portion 24 of the downstream fin 3 penetrates. Therefore, when the user moves the knob 23 in the long side direction of the downstream fin 3, even if the knob 23 is deformed so as to be inclined in the thickness direction with respect to the downstream fin 3, the protruding member 29 extending as described above is formed. The above deformation can be suppressed by receiving the force from the knob 23.

(3) A plurality of projecting members 29 spaced in the short side direction of the downstream fin 3 are pressed against the inner surface of the knob 23 (through hole 25). Therefore, when the user moves the knob 23 in the long side direction of the downstream fin 3, the knob 23 can be supported by the plurality of projecting members 29. Therefore, when the knob 23 is moved in the long side direction of the downstream fin 3, the knob 23 is less likely to tilt with respect to the downstream fin 3, and it is possible to prevent the tilt from adversely affecting the smooth movement of the knob 23.

The above embodiment can be changed as follows, for example. The above embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.
The protruding member 29 may have the shape shown in FIG. The protruding member 29 penetrates the penetrating portion 24 in the thickness direction of the downstream fin 3. The end portion of the main body 29a of the projecting member 29 opposite to the end portion 29b is a retaining portion 29c. The retaining portion 29c has a width larger than that of the main body 29a. As a result, the projecting member 29 is prevented from coming off in the direction of projecting from the surface 24a with respect to the penetrating portion 24.

When the knob 23 is moved in the long side direction of the downstream fin 3, the protruding member 29 is pulled in the direction of being pulled out from the penetrating portion 24 by the frictional force between the protruding member 29 and the knob 23. At this time, the protrusion of the projecting member 29 from the penetrating portion 24 is suppressed by the retaining portion 29c having a width larger than that of the main body 29a of the projecting member 29.

-In the downstream fin 3 shown in FIG. 6, the protrusion 28 may be omitted. In this case, the retaining portion 29c is preferably located closer to the surface 24b than the surface 24a of the penetrating portion 24. According to this configuration, when the knob 23 is attached to the downstream fin 3, the retaining portion 29c does not come into contact with the inner surface of the knob 23 (through hole 25). Therefore, even if a dimensional error of the retaining portion 29c in the thickness direction of the downstream fin 3 occurs at the time of manufacturing, the dimensional error does not affect the width X1 of the penetrating portion 24. Therefore, regardless of the dimensional error of the retaining portion 29c, the amount of protrusion of the protruding member 29 from the surface 24b can be determined so as to satisfy the relationship of the above formula (1).

The protrusion 28 may be omitted in the penetrating portion 24, and the shape of the protruding member 29 may be changed to the shape shown in FIG. The protruding member 29 penetrates the penetrating portion 24 in the thickness direction of the downstream fin 3. The end portion 29d of the main body 29a of the projecting member 29 opposite to the end portion 29b has the same shape as the end portion 29b. That is, the end portion 29d protrudes from the surface 24b of the penetrating portion 24. The end portion 29d has a width larger than that of the main body 29a. In this configuration, when the knob 23 is attached to the downstream fin 3, the end portion 29b and the end portion 29d of the projecting member 29 are pressed against the inner surface of the knob 23 (through hole 25).

When the knob 23 is moved in the long side direction of the downstream fin 3, the protruding member 29 is pulled in the direction of being pulled out from the penetrating portion by the frictional force between the protruding member 29 and the knob 23. At this time, the protrusion of the projecting member 29 from the penetrating portion 24 is suppressed by the end portions 29b and 29d having a width larger than that of the main body 29a.

As shown in FIG. 8, a projecting member 30 having the same shape as the projecting member 29 in FIG. 5 may be provided on the surface 24b side of the penetrating portion 24. In this case, it is preferable to provide a plurality of projecting members 30 at intervals in the short side direction (left-right axis direction in FIG. 8) of the downstream fin 3. Further, the positions of the projecting member 29 and the projecting member 30 are set in the left-right axial direction of FIG. 8 so that the positions of the projecting member 29 and the projecting member 30 do not overlap in the thickness direction of the downstream fin 3 (vertical axis direction in FIG. 8). It is preferable to shift to. As a result, when the knob 23 is moved in the long side direction of the downstream fin 3, the knob 23 is less likely to tilt with respect to the downstream fin 3.

The protruding member 29 does not necessarily have to extend in the long side direction of the downstream fin 3.
The end portion 29b of the projecting member 29 does not necessarily have to have a width larger than that of the main body 29a.

-A plurality of projecting members 29 do not necessarily have to be provided.
The plurality of projecting members 30 shown in FIG. 8 do not necessarily have to be provided.
The mounting piece 26 and the elastic member 27 of the knob 23 may be omitted.
