Description

Technical Field

[0001] The present invention relates to a wind direction adjusting device.

Background Art

[0002] In vehicles such as automobiles, a wind direction adjusting device that can change the direction of the air blown into the vehicle is installed. The wind direction adjusting device may also be called a ventilator, a register, an air outlet (or simply an outlet), etc., and contributes to improving the comfort performance inside the vehicle by heating and cooling.

[0003] For example, Japanese Patent Application Laid-Open No. 2009-96279 (Patent Document 1) describes a wind direction adjusting device (air blowing direction changing device) that rotates a rotating fin by operating an operation knob. The wind direction adjusting device of Patent Document 1 includes a wind guiding fin, a rotating fin rotatably arranged upstream of the wind guiding fin, an operation knob attachable to the wind guiding fin, and an elastic member fixed to the wind guiding fin.

[0004] The operation knob is attached to the wind guiding fin so as to be movable along the wind guiding fin. The operation knob can rotate the rotating fin by moving on the wind guiding fin by an operation by a driver or the like. The elastic member is fixed to the wind guiding fin so as to be in sliding contact with the operation knob in order to generate an operation load (operation torque) when the operation knob is operated. The operation knob is formed with support ribs extending in the moving direction of the operation knob, and these support ribs are in contact with the elastic member so as to be in linear sliding contact with the elastic member when the operation knob moves.

[0005] In Patent Document 1, since the support ribs formed on the operation knob can be in linear sliding contact with the elastic member, the possibility of uneven wear occurring on the support ribs or the elastic body is reduced, and it is explained that the operation feeling of the operation knob is difficult to change with use.

[0006] Patent Document 1 Japanese Unexamined Patent Application Publication No. 2009-96279 Summary of the Invention Problems to be Solved by the Invention

[0007] In recent years, as a wind direction adjusting device, in addition to generating the above-described operating load when operating the operation knob, when the operation knob reaches a predetermined position (for example, a position where the fins are held in a direction in which the blowing direction of the wind becomes neutral), a device that gives a clicking feeling to the user who operates the operation knob has come to be manufactured.

[0008] As a means for generating such a clicking feeling, it is known to incorporate a plunger inside the wind direction adjusting device. However, when incorporating a plunger into the wind direction adjusting device, since the installation area of the plunger must be secured separately from the elastic member that generates the operating load (operating torque), consideration is required to appropriately set the plunger within the limited space. In addition, the plunger requires a spring member that generates a biasing force (for example, a spring) and a plunger main body portion that houses the spring member, etc., so the installation of the plunger is one of the factors that increase the manufacturing cost of the wind direction adjusting device.

[0009] The present invention has been made in view of the above-described conventional problems, and an object thereof is to provide a wind direction adjusting device capable of generating an operating load and a clicking feeling with a simple structure. Means for Solving the Problems

[0010] In order to achieve the above object, a wind direction adjusting device provided by the present invention is a wind direction adjusting device having an operation unit for operating a wind direction adjusting unit and an opposing unit provided with a portion facing at least a part of the operation unit, wherein the operation unit is arranged to be movable or rotatable with respect to the opposing unit, and is provided with an elastic member having elasticity and generating an operation load during operation of the operation unit, and a click member formed harder than the elastic member, the elastic member is attached to one of the operation unit and the opposing unit, and has a sliding contact portion that slidably contacts the other of the operation unit and the opposing unit when the operation unit moves or rotates, and the click member is held by the elastic member so as to be able to advance and retreat, and when the operation unit moves or rotates, it slidably contacts the other of the operation unit and the opposing unit and advances and retreats with respect to the elastic member to generate a click feeling, which is a wind direction adjusting device.

[0011] In the wind direction adjusting device of the present invention, it is preferable that one of the operation unit and the opposing unit has a promoting structure that promotes deformation of the elastic member when the click member advances and retreats. In this case, the promoting structure is preferably formed by a concave portion or a hole portion provided in one of the operation unit and the opposing unit.

Effects of the Invention

[0012] According to the wind direction adjusting device of the present invention, with a simple structure, an operation load can be generated when operating the operation unit, and a click feeling can be generated when the operation unit reaches a predetermined position, so that a good operation feeling can be obtained when rotating the fin.

Mode for Carrying Out the Invention

[0014] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings by giving examples.

Example

[0015] FIG. 1 is a front view schematically showing a state in which the air direction adjusting device of the first embodiment is attached to an interior member. FIG. 2 is a cross-sectional view schematically showing a cross-section of a main part of the air direction adjusting device of the first embodiment. FIG. 3 is a perspective view schematically showing a spacer member and a click member of the first embodiment. FIG. 4 is a cross-sectional view showing the relationship between the spacer member and the click member, the click projection provided on the horizontal fin, and the deformation promoting recess provided on the operation knob.

[0016] The air direction adjusting device 1 of the first embodiment is attached to an interior member 5 (not shown) such as an instrument panel or a center console in the passenger compartment of an automobile, for example. By being connected to an air conditioner (not shown) installed in the vehicle, the air direction adjusting device 1 can blow out the air that has been temperature-adjusted by the air conditioner into the passenger compartment.

[0017] Here, regarding the wind direction adjustment device 1, the front-rear direction is the direction along the air flow direction in the case body of the wind direction adjustment device 1 when the vertical fins 20 described later are held in the neutral position (vertical position). In this case, the downstream side of the air flow is regarded as the front, and the upstream side is regarded as the rear. The up-down direction and the left-right direction are the vertical direction (height direction) and the horizontal direction (width direction) when the wind direction adjustment device 1 is viewed from the blowout port side.

[0018] The wind direction adjustment device 1 of the first embodiment includes a case body (not shown) having a flow path for circulating air inside, a horizontal fin 10 disposed at the blowout port side end of the case body, a plurality of vertical fins 20 disposed upstream of the horizontal fin 10, an operation knob 30 attached to the horizontal fin 10 and operated when rotating the vertical fins 20, and a link member (not shown) that connects the plurality of vertical fins 20 to interlock the rotation of each vertical fin 20. In the first embodiment, the vertical fins 20 are provided as a wind direction adjustment unit that adjusts the left-right direction of the wind blowing out from the wind direction adjustment device 1. In the first embodiment, the shape, structure, size, number of installations, installation position, etc. of the vertical fins 20 are not particularly limited, and the shape, structure, installation position, etc. of the link member are also not particularly limited.

[0019] Furthermore, as shown in FIGS. 2 to 4, the wind direction adjustment device 1 includes a spacer member (elastic member) 40 formed of a soft synthetic resin having elasticity, and a click member 50 held by the spacer member 40. The spacer member 40 and the click member 50 are installed between the horizontal fin 10 and the operation knob 30 so as not to be visible from the outside (particularly, not to be visible from the front side of the wind direction adjustment device 1).

[0020] The case body (not shown) of the wind direction adjustment device 1 is installed on the back side of the interior member 5 and is connected to a duct (not shown) that conveys air temperature-adjusted by the air conditioner. The case body has a substantially cylindrical shape or a substantially rectangular prism shape, and an air flow path is formed inside the case body along the front-rear direction. A blowout port for blowing air into the vehicle interior is provided at the front end portion (downstream side edge portion) of the case body.

[0021] The horizontal fin 10 is arranged along the left - right direction, and the left and right side ends of the horizontal fin 10 are fixed to the case body so as not to rotate in the up - down direction. In the present invention, the horizontal fin 10 may be rotatably held by the case body in the up - down direction. Also, although one horizontal fin 10 is provided in the wind direction adjusting device 1 of this embodiment, in the present invention, a plurality of horizontal fins including the horizontal fin to which the operation knob 30 is attached may be provided in the wind direction adjusting device.

[0022] The horizontal fin 10 has a horizontal fin main body portion 11 formed in a plate shape that is long in the left - right direction, a slide wall portion 12 extending downward from the horizontal fin main body portion 11, and one click convex portion 13 protruding forward from the slide wall portion 12 (see FIGS. 2 and 4).

[0023] The horizontal fin main body portion 11 has a flat upper surface and a lower surface arranged perpendicular to the up - down direction, and a curved front end surface that is convexly curved from the upper surface to the lower surface. A knob attachment portion 14 to which the operation knob 30 is attached is provided behind the slide wall portion 12 on the horizontal fin main body portion 11. In the present invention, the structure and installation position of the knob attachment portion 14 on the horizontal fin 10 are not particularly limited.

[0024] When looking at a cross - section perpendicular to the left - right direction of the horizontal fin 10 (see FIG. 2), the slide wall portion 12 of the horizontal fin 10 is formed to protrude in a flat plate shape downward from the lower surface of the horizontal fin main body portion 11. This slide wall portion 12 is arranged straight along the left - right direction (see FIG. 4) and has a flat front wall surface and a rear wall surface.

[0025] The slide wall portion 12 of the first embodiment is arranged to face the knob front end portion 32 (specifically, the rear wall portion of the knob front end portion 32) of the operation knob 30 described later. The lateral fin 10 of the first embodiment provided with such a slide wall portion 12 serves as an opposing portion that includes a portion facing at least a part of the operation knob 30 with respect to the operation knob 30. The slide wall portion 12 abuts the rear end portion of the click member 50 held by the spacer member 40 against the front wall surface of the slide wall portion 12, and is provided so that the rear end portion of the click member 50 is in sliding contact when the operation knob 30 moves in the left-right direction along the lateral fin 10.

[0026] One click projection 13 provided on the lateral fin 10 is formed, for example, to protrude forward in a triangular shape on the front wall surface of the slide wall portion 12 when looking at a cross-section orthogonal to the vertical direction of the slide wall portion 12 and the click projection 13 (see FIG. 4). The click projection 13 is continuously provided in the range from the upper end position to the lower end position of the slide wall portion 12 in the vertical direction. The click projection 13 is formed in a size (protrusion amount from the slide wall portion 12) such that the click member 50 held by the spacer member 40 can overcome the click projection 13 by moving the operation knob 30.

[0027] The installation position of the click projection 13 is set in a position such that when the operation knob 30 is moved to a predetermined position on the lateral fin 10 in the left-right direction, the click member 50 provided on the operation knob 30 side reaches the predetermined position when it overcomes the click projection 13. In this case, the predetermined position reached by the operation knob 30 includes, for example, the position of the operation knob 30 that holds the directions of the plurality of vertical fins 20 parallel to the neutral position in the front-rear direction, and the position of the operation knob 30 where the plurality of vertical fins 20 close the flow path of the case body, etc., and at least one of these positions of the operation knob 30 can be selected as the predetermined position.

[0028] Also, in the first embodiment, one click projection 13 is provided on the slide wall portion 12 (see FIG. 4). However, in the present invention, the number of click projections 13 protruding from the slide wall portion 12 is not particularly limited. For example, in the case of this embodiment, two click projections 13 may be provided at positions where the click member 50 is sandwiched and held by the two click projections 13 when the operation knob 30 is moved to the predetermined position as described above. Further, in the present invention, instead of providing the click projection 13, a click recess having a shape recessed from the front wall surface of the slide wall portion 12 may be provided on the slide wall portion 12.

[0029] The operation knob 30 is attached to the horizontal fin 10 so as to be movable in the left-right direction, and the front end portion of the operation knob 30 is arranged so as to be located in front of the front end portion of the horizontal fin 10. The operation knob 30 has a knob main body portion 31 and a fixing rib 36 protruding from the knob main body portion 31.

[0030] When the cross section of the knob main body portion 31 perpendicular to the left-right direction of the operation knob 30 is viewed (see FIG. 2), the knob front end portion 32 visible from the front side of the wind direction adjusting device 1, a base portion 33 extending rearward from the knob front end portion 32 and formed to be thinner in thickness (dimension in the up-down direction) than the knob front end portion 32, and a knob rear end portion 34 provided on the rear side of the base portion 33 and formed to be thicker than the base portion 33. In this case, a step portion for changing the thickness is formed at the boundary portion between the knob front end portion 32 and the base portion 33.

[0031] The knob front end portion 32 is formed such that the thickness between the upper surface and the lower surface of the knob front end portion 32 is the same as or substantially the same as the thickness of the horizontal fin main body portion 11. The front end surface of the knob front end portion 32 is formed into a curved surface that curves convexly forward.

[0032] The rear wall portion of the front end portion 32 of the knob is provided so as to form a stepped portion between the front end portion 32 of the knob and the base portion 33. A deformation promoting recess 35 is formed in the rear wall portion of the front end portion 32 of the knob as a promoting structure (or an allowing structure that allows deformation) for promoting the deformation of the spacer member 40. The deformation promoting recess 35 is provided at a position corresponding to a housing portion 43, which will be described later, of the spacer member 40 fixed to the operation knob 30 in the left-right direction. Further, the deformation promoting recess 35 is continuously formed along the vertical direction from the position of the upper surface of the front end portion 32 of the knob to the position of the base portion 33.

[0033] The deformation promoting recess 35 has a flat rectangular bottom surface, left and right side wall surfaces, and a lower end surface, and is formed to be recessed in a rectangular parallelepiped shape forward from the rear end surface of the front end portion 32 of the knob. The dimension of the deformation promoting recess 35 in the left-right direction (the interval between the left and right side wall surfaces of the deformation promoting recess 35) is set to be larger than the diameter of a columnar click body portion 51, which will be described later, of the click member 50, and is also set to be smaller than the dimension of the housing portion 43 of the spacer member 40 in the left-right direction.

[0034] The base portion 33 is formed with a certain thickness between the front end portion 32 of the knob and the rear end portion 34 of the knob in the front-rear direction. The base portion 33 has a flat lower surface continuously formed from the lower surface of the front end portion 32 of the knob and a flat upper surface disposed on the opposite side of the lower surface. On the upper surface of the base portion 33, a fixing rib 36 protruding upward from the base portion 33 is provided for holding the spacer member 40 at a predetermined position of the operation knob 30 (see FIGS. 2 and 4). The fixing rib 36 has a shape of a rectangular parallelepiped elongated in the left-right direction.

[0035] An engaging portion 34a that engages with the knob attachment portion 14 of the horizontal fin 10 is provided at the rear end portion 34 of the knob. In the present invention, the structure and installation position of the engaging portion 34a of the rear end portion 34 of the knob are not particularly limited.

[0036] The spacer member (elastic member) 40 is disposed between the lateral fins 10 and the operation knob 30, and is held by the operation knob 30 in a state where a part of the spacer member 40 is in contact with the lateral fins 10. Thereby, when the operation knob 30 is operated and moves in the left - right direction, frictional resistance is generated at the contact portion between the spacer member 40 (particularly, the sliding contact block portion 42 of the spacer member 40 described later) and the lateral fins 10, and an operation load (operating force) can be obtained.

[0037] The spacer member 40 has a spacer main body portion 41 having a substantially rectangular parallelepiped shape elongated in the left - right direction, two sliding contact block portions (sliding contact portions) 42 integrally provided on the upper surface of the spacer main body portion 41, a housing portion 43 integrally provided on one side surface (left side surface) in the left - right direction of the spacer main body portion 41, and an engaging concave portion 45 recessed in the lower surface portion of the spacer main body portion 41 for housing the fixing rib 36.

[0038] The spacer main body portion 41 has a front end face and a rear end face orthogonal to the front - rear direction, an upper end face and a lower end face orthogonal to the up - down direction, and a right side face orthogonal to the left - right direction. The dimension of the spacer main body portion 41 in the front - rear direction (that is, the dimension between the front end face and the rear end face of the spacer main body portion 41) is set smaller than the interval between the sliding wall portion 12 of the lateral fins 10 in the wind direction adjusting device 1 and the rear end face of the knob front end portion 32 in the operation knob 30.

[0039] The two sliding contact block portions 42 respectively project upward from the upper surface of the spacer main body portion 41 in a substantially rectangular parallelepiped shape or a substantially quadrangular prism shape. The sliding contact block portion 42 has a first sliding contact block portion 42a disposed at the right - hand end of the spacer member 40 and a second sliding contact block portion 42b disposed at the central portion of the spacer member 40 in the left - right direction.

[0040] The first folding contact block portion 42a and the second folding contact block portion 42b are provided with the same shape and the same size as each other, and are arranged to be spaced apart in the left-right direction from each other. The dimension of the first folding contact block portion 42a and the second folding contact block portion 42b in the front-rear direction (that is, the dimension between the front end face and the rear end face of the folding contact block portion 42) is set to be the same size as the dimension of the spacer main body portion 41 in the front-rear direction.

[0041] The first folding contact block portion 42a and the second folding contact block portion 42b each have a flat upper end face arranged perpendicular to the vertical direction. The dimension of the spacer member 40 of the first embodiment in the vertical direction from the upper end face of the folding contact block portion 42 to the lower end face of the spacer main body portion 41 is made the same size as the dimension of the space in the vertical direction from the lower surface of the horizontal fin 10 in the wind direction adjusting device 1 to the upper surface of the base portion 33 of the operation knob 30, or is formed to be larger than the dimension of the space in the vertical direction.

[0042] Thereby, the two folding contact block portions 42 provided on the spacer member 40 are held in a state where their respective upper end faces are in surface contact with the lower surface of the horizontal fin 10 in the wind direction adjusting device 1. Further, when the operation knob 30 is moved in the left-right direction with respect to the horizontal fin 10, the upper end faces of the two folding contact block portions 42 can be brought into sliding contact with the lower surface of the horizontal fin 10, thereby generating an operation load (frictional resistance) during the operation of the operation knob 30.

[0043] In the first embodiment, for example, by changing at least one of changing the number of folding contact block portions 42 provided on the spacer member 40, changing the shape and size of each folding contact block portion 42, and changing the dimension in the vertical direction from the upper end face of the folding contact block portion 42 to the lower end face of the spacer main body portion 41, the magnitude of the operation load generated during the operation of the operation knob 30 can be easily adjusted.

[0044] The accommodating portion 43 of the spacer member 40 is formed to accommodate and hold the click member 50. Specifically, the accommodating portion 43 is formed in a quadrangular prism shape and has a front end face and a rear end face orthogonal to the front-rear direction, an upper end face and a lower end face orthogonal to the up-down direction, and a left side face orthogonal to the left-right direction. The front end face, the rear end face, and the lower face of the accommodating portion 43 are continuously formed so as to form a single plane with the front end face, the rear end face, and the lower face of the spacer main body portion 41, respectively. The upper end face of the accommodating portion 43 is arranged at a position higher than the upper end face of the spacer main body portion 41 and lower than the upper end face of the sliding contact block portion 42 in the up-down direction.

[0045] In the accommodating portion 43, an accommodation space portion 44 extending forward from the rear end face of the accommodating portion 43 is provided corresponding to the shape and size of the click member 50. The accommodation space portion 44 of the present embodiment is formed so that the cross-sectional shape orthogonal to the front-rear direction is square, and is formed in a size capable of accommodating the click member 50 and holding it in a certain posture (specifically, a posture in which the central axis of the click member 50 is along the front-rear direction). A bottom face portion 43a is provided between the front end face of the accommodating portion 43 and the accommodation space portion 44.

[0046] The bottom face portion 43a of the accommodating portion 43 is formed to be elastically deformable. Thereby, for example, when the click member 50 held in the accommodation space portion 44 is pressed forward, the bottom face portion 43a of the accommodating portion 43 in contact with the click member 50 elastically deforms by receiving the pressing force from the click member 50. Further, when the pressing force from the click member 50 is released, the bottom face portion 43a of the accommodating portion 43 can elastically return to its original shape before receiving the pressing force. Particularly in the wind direction adjusting device 1 of the present Embodiment 1, as described above, since the deformation promoting recess 35 is provided in the rear wall portion of the knob front end portion 32 of the operation knob 30, when the bottom face portion 43a of the accommodating portion 43 receives the pressing force from the click member 50, the bottom face portion 43a can be easily and smoothly elastically deformed.

[0047] The engaging recess 45 of the spacer member 40 is provided on the lower surface portion of the spacer main body portion 41, and is formed in a shape and size corresponding to the fixing rib 36 so as to accommodate and engage (fit) the fixing rib 36 provided on the operation knob 30. By engaging the fixing rib 36 of the operation knob 30 with the engaging recess 45 of the spacer member 40, the spacer member 40 can be attached to a predetermined position of the operation knob 30 and stably held. In the first embodiment, the spacer member 40 is held by the operation knob 30 in a state where the lower end surfaces of the spacer main body portion 41 and the accommodating portion 43 are in contact with the base portion 33 of the operation knob 30, and the front end surfaces of the spacer main body portion 41 and the accommodating portion 43 are in contact with the knob front end portion 32.

[0048] The click member 50 is formed of a synthetic resin harder than the spacer member 40. The click member 50 has a click body portion 51 having a cylindrical shape, a click front end portion 52 and a click rear end portion 53 having a hemispherical or substantially hemispherical shape, and is formed in an oval or capsule shape when the click member 50 is viewed from the side of the click body portion 51.

[0049] The click member 50 is held in the accommodating portion 43 of the spacer member 40 in a posture where the central axis of the click member 50 is along the front-rear direction by inserting the click member 50 into the accommodating space portion 44 of the spacer member 40 from the click front end portion 52 of the click member 50, and at least the click rear end portion 53 of the click member 50 protrudes from the accommodating portion 43. Further, in the wind direction adjusting device 1, the click member 50 is held in a state where the click rear end portion 53 contacts the slide wall portion 12 of the horizontal fin 10 and the bottom surface portion 43a of the accommodating portion 43 of the spacer member 40 is elastically deformed slightly.

[0050] The click member 50 is held so as to be movable forward and backward along the front-rear direction from the position of the click member 50 shown in FIG. 2 with respect to the spacer member 40 by utilizing the elasticity of the spacer member 40. For this reason, when the operation knob 30 is moved in the left-right direction with respect to the horizontal fin 10, the click member 50 held by the spacer member 40 can bring the click rear end portion 53 into sliding contact with the slide wall portion 12 of the horizontal fin 10.

[0051] Further, when the click member 50 moves from one side (for example, the left side) in the left-right direction to the other side (for example, the right side) of the click convex portion 13 protruding from the slide wall portion 12, the click member 50 is pushed forward by the click convex portion 13, and thus is once retracted (moves forward) into the accommodation portion 43 of the spacer member 40. Then, after getting over the click convex portion 13, the click member 50 pops out (moves backward) by the elastic force of the bottom surface portion 43a of the spacer member 40, thereby making a movement of hitting against the slide wall portion 12.

[0052] Thereby, the click member 50 can smoothly get over the click convex portion 13. Further, a click feeling can be generated by a change in load when the click member 50 gets over the click convex portion 13, and furthermore, a click sound can be generated when the click member 50 hits against the slide wall portion 12.

[0053] In the present First Embodiment, at least one of changing the shape and size of the click member 50 (particularly, the click rear end portion 53), changing the shape and size of the click convex portion 13, changing the shape of the accommodation portion 43 in the spacer member 40 and the thickness of the bottom surface portion 43a of the accommodation portion 43, and changing the shape and size of the deformation promoting concave portion 35 provided in the operation knob 30 is performed, whereby the magnitude of the load of the click feeling generated when the click member 50 gets over the click convex portion 13, the degree of change in the load of the click feeling, the magnitude of the click sound, and the like can be easily adjusted.

[0054] In the wind direction adjusting device 1 of the first embodiment as described above, the spacer member 40 is held between the lateral fin 10 and the operation knob 30 in a state where the lower end surface of the spacer main body portion 41 is brought into contact with the base portion 33 of the operation knob 30 and the upper end surfaces of the two sliding contact block portions 42 are brought into contact with the lower surface of the lateral fin 10 as described above. Thereby, when the operation knob 30 is operated and moved in the left - right direction, an appropriate operating load can be stably generated by the frictional force between the two sliding contact block portions 42 of the spacer member 40 and the lower surface of the lateral fin 10.

[0055] Furthermore, in the wind direction adjusting device 1, when the operation knob 30 reaches a predetermined position, the click member 50 that is held by the spacer member 40 so as to be able to advance and retreat can generate a click feeling and a click sound by overcoming the click convex portion 13 provided on the slide wall portion 12 of the lateral fin 10 as described above.

[0056] That is, in the wind direction adjusting device 1 of the first embodiment, by using a simple structure in which the elastic spacer member 40 and the click member 50 that is held by the spacer member 40 so as to be able to advance and retreat are installed between the lateral fin 10 and the operation knob 30, both the operating load and the click feeling when operating the operation knob 30 can be generated without using a plunger like a conventional wind direction adjusting device.

[0057] Also, in the first embodiment, in order to obtain a click feeling, instead of using a plunger that requires an installation area separately from the elastic member, a small - sized click member 50 is used and the click member 50 is held by the spacer member 40 so as to be able to advance and retreat. For this reason, compared with a conventional wind direction adjusting device in which a click feeling can be obtained, the mechanism for generating the click feeling can be miniaturized, and furthermore, the wind direction adjusting device 1 can be miniaturized. Also, by eliminating the need for a plunger, the number of parts of the wind direction adjusting device 1 can be reduced and the manufacturing cost can be reduced.

[0058] Furthermore, in the first embodiment, for example, by manufacturing the wind direction adjusting device 1 without using the click member 50, it is possible to provide a wind direction adjusting device 1 that does not generate a click feeling and a click sound. That is, in the wind direction adjusting device 1 of the first embodiment, the presence or absence of the click feeling and the click sound can be easily set depending on whether or not the click member 50 is installed.

[0059] In the first embodiment, the wind direction adjusting device 1 may be formed by changing the shape, structure, size, etc. of the click member 50 and / or the spacer member 40. For example, as one of the modified examples of the first embodiment (the first modified example), instead of the click member 50 shown in FIG. 3, for example, a mushroom-shaped click member (not shown) having a click rear end portion in the shape of a pyramid or a cone and a click shaft portion extending columnarly forward from the center portion of the click rear end portion is used, or a click member 50 of the first embodiment having an oval or capsule shape is further provided with a flange portion extending radially outward from the click body portion 51 (not shown). By using this, a wind direction adjusting device may be formed.

[0060] Furthermore, as another modified example of the first embodiment (the second modified example), instead of using the spacer member 40 shown in FIG. 3, a spacer member (not shown) in which the accommodating portion 43 is formed by a square columnar base portion and a holding shaft protruding columnarly rearward from the base portion is used, and thus a wind direction adjusting device may be formed. Also, in the case of the second modified example, instead of using the click member 50 shown in FIG. 3, a click member (not shown) having a long and thin shape with a rounded tip like a pistol bullet and a receiving recess formed recessedly rearward from the front end surface of the click body portion and accommodating the holding shaft of the spacer member is held by the spacer member so as to be able to advance and retreat.

[0061] Also, in the above-described Example 1, the spacer member 40 is held by the operation knob 30 by inserting and fitting the fixing rib 36 provided on the operation knob 30 into the engaging recess 45 of the spacer member 40. However, in the present invention, the spacer member 40 may be fixed to the base portion 33 of the operation knob 30 by, for example, adhesion or welding.

[0062] Furthermore, the click member 50 may be attached to the spacer member 40 so as to be able to advance and retreat in the front-rear direction by, for example, two-color molding. Furthermore, in the present invention, the spacer member 40 and the click member 50 may be attached to the lateral fins 10, and a wind direction adjusting device may be formed by providing the operation knob 30 with a slide wall portion 12 that slidably contacts the click member 50 and a click convex portion 13 that protrudes from the slide wall portion 12.

[0063] Even in the wind direction adjusting device according to the modification of Example 1 as described above, an operation load can be generated when the operation knob 30 is operated, and a click feeling and a click sound can be generated when the operation knob 30 is operated and moved to a predetermined position. Furthermore, in these cases, it is possible to generate a click feeling different from that of Example 1 and a click sound different in volume and / or pitch from that of Example 1.

Example

[0064] FIG. 5 is a cross-sectional view schematically showing a cross-section of a main part of the wind direction adjusting device according to the present Example 2. FIG. 6 is a schematic view showing the spacer member and the click member of the present Example 2 with a part of the spacer member in cross-section. FIG. 7 is a cross-sectional view showing the relationship between the spacer member and the click member, the click convex portion provided on the operation dial, and the deformation promoting hole portion provided on the dial support portion.

[0065] The wind direction adjustment device of the second embodiment includes a case body (not shown) for allowing air to flow inside, a plurality of vertical fins (not shown) rotatably held by the case body, an operation dial 60 operated when rotating the vertical fins, and a link member (not shown) for connecting the plurality of vertical fins to interlock the rotation of each vertical fin. In the second embodiment, the vertical fins (not shown) are provided as a wind direction adjustment unit for adjusting the direction of the wind blowing out from the wind direction adjustment device to the left and right. In the second embodiment, the shapes, structures, etc. of the case body, the vertical fins, and the link member are not particularly limited.

[0066] As shown in FIGS. 5 to 7, the wind direction adjustment device of the second embodiment includes a spacer member (elastic member) 80 formed of a soft synthetic resin having elasticity, and a click member 90 held by the spacer member 80. The spacer member 80 and the click member 90 are installed inside the operation dial 60.

[0067] The operation dial 60 includes a dial portion 61 and a dial support portion 71 that rotatably supports the dial portion 61. The dial portion 61 and the dial support portion 71 are arranged so as to sandwich the spacer member 80 and the click member 90 from above and below. The operation dial 60 is connected to one of the plurality of vertical fins via a transmission mechanism (not shown), and by rotating the dial portion 61 in the first rotation direction or the second rotation direction opposite to the first rotation direction, the vertical fin can be rotated in one or the other direction to change the direction of the vertical fin. This wind direction adjustment device is installed with at least a part of the dial portion 61 of the operation dial 60 exposed inside the vehicle from an interior member (for example, an instrument panel).

[0068] The dial portion 61 includes a disc-shaped dial main body portion 62, a pair of sliding protrusion portions 63 that protrude downward from the lower surface of the dial main body portion 62, a sliding surface 64 that slidably contacts the tip of the click member 90, and a single click convex portion 65 that protrudes downward from the sliding surface 64. The dial main body portion 62 is formed with a certain thickness. A circular insertion hole portion for inserting a support shaft portion (described later) of the dial support portion 71 is formed at the center of the dial main body portion 62.

[0069] The two sliding protrusion portions 63 are respectively arranged along the circumferential direction of the dial main body portion 62. The sliding protrusion portion 63 has a first sliding protrusion portion 63a arranged on the outer side in the radial direction of the dial main body portion 62 and a second sliding protrusion portion 63b arranged on the inner side in the radial direction. The lower end surface of each sliding protrusion portion 63 is formed as a curved surface that curves convexly downward. Each sliding protrusion portion 63 contacts the upper surface of a sliding flange portion 82 (described later) of the spacer member 80 and is arranged so as to slidably contact the upper surface of the sliding flange portion 82 when the dial main body portion 62 rotates.

[0070] The sliding surface 64 of the dial portion 61 is provided on the lower surface (back surface) of the dial main body portion 62. The sliding surface 64 is continuously and flatly formed along the circumferential direction of the dial main body portion 62 between the pair of sliding protrusion portions 63. The click convex portion 65 of the dial portion 61 is formed to protrude in a triangular shape downward from the sliding surface 64 when, for example, a cross-section along the circumferential direction of the dial main body portion 62 is viewed (see FIG. 7).

[0071] The click convex portion 65 is provided along the radial direction across the pair of sliding protrusion portions 63. The click convex portion 65 is formed to have a size (protrusion amount) that allows the click member 90 held by the spacer member 80 to move forward and backward in the vertical direction and overcome it when the dial main body portion 62 is rotated.

[0072] The installation position of the click projection 65 is set to a position where, in the circumferential direction, when the dial main body 62 is rotated to a predetermined position with respect to the dial support portion 71, the dial main body 62 reaches the predetermined position when the click member 90 provided on the dial support portion 71 side gets over the click projection 65.

[0073] In addition, in the present second embodiment, one click projection 65 is provided on the slide surface 64. However, in the present invention, the number of click projections 65 provided is not particularly limited. For example, in the case of the present embodiment, two click projections 65 may be provided at positions where, when the dial main body 62 is rotated to the predetermined position as described above, the click member 90 is sandwiched and held by the two click projections 65. Further, in the present invention, instead of providing the click projection 65 on the slide surface 64, a click recess having a shape recessed from the slide surface 64 may be provided.

[0074] The dial support portion 71 includes a support base portion 72, a base portion 73 integrally formed on the upper surface of the support base portion 72, and a pair of two support arm portions 74 that project upward from the base portion 73 and are formed to be elastically deformable.

[0075] The support base portion 72 is formed in a flat plate shape. In the case of the present second embodiment, the support base portion 72 is formed by a part of a case body (not shown) of the wind direction adjusting device. The support base portion 72 is arranged to face the dial main body 62 of the dial portion 61. The dial support portion 71 of the present second embodiment including such a support base portion 72 serves as an opposing portion that includes a portion facing at least a part of the dial portion 61 with respect to the dial portion 61 which is an operation portion.

[0076] The support base portion 72 is provided with a fixing portion 75 for fixing the spacer member 80 and a deformation promoting hole portion 76. The fixing portion 75 is formed corresponding to the shape and size of the spacer member 80. For example, the fixing portion 75 of the present second embodiment has a cylindrical fixing wall portion 75a, a bottom surface portion 75b that supports the spacer member 80, and a holding space portion formed by being surrounded by the fixing wall portion 75a and the bottom surface portion 75b.

[0077] By engaging and attaching the spacer member 80 to the fixing portion 75, the spacer member 80 can be held so as not to move and fixed to the dial support portion 71. Further, a sliding contact flange portion 82 of the spacer member 80 is sandwiched between the fixing portion 75 of the spacer member 80 and the sliding contact protruding portion 63 of the dial portion 61.

[0078] The deformation promoting hole portion 76 is provided in the bottom surface portion 75b of the fixing portion 75 as a promoting structure for promoting the deformation of the spacer member 80. The deformation promoting hole portion 76 is formed so as to penetrate the bottom surface portion 75b of the fixing portion 75 at a position corresponding to a spacer main body portion 81 of the spacer member 80 to be described later with respect to the circumferential direction and the radial direction of the dial main body portion 62. The deformation promoting hole portion 76 is formed in a circular shape having a diameter larger than the diameter of the columnar click body portion 91 of the click member 90, for example, in a bottom view when the operation dial 60 is viewed from below.

[0079] The base portion 73 of the dial support portion 71 and a pair of support arm portions 74 rotatably hold the dial main body portion 62 with respect to the dial support portion 71. In the present invention, the shape, structure, etc. of the dial support portion 71 are not particularly limited as long as the dial support portion 71 can rotatably attach the dial main body portion 62 and hold the spacer member 80 at a predetermined position.

[0080] The spacer member (elastic member) 80 is disposed between the dial portion 61 and the dial support portion 71, and is held by the dial support portion 71 in a state where a part of the spacer member 80 is in contact with the sliding contact protruding portion 63 of the dial portion 61. Thereby, when the dial portion 61 is operated and rotated, frictional resistance is generated at the contact portions between the spacer member 80 and the two sliding contact protruding portions 63, and an operation load (operation force) can be obtained.

[0081] The spacer member 80 has a spacer main body portion 81 formed in a columnar shape and a sliding contact flange portion 82 integrally formed at the upper end portion of the spacer main body portion 81. The spacer main body 81 is formed to accommodate and hold the click member 90. Specifically, the spacer main body 81 has a cylindrical body portion and a bottom surface portion 81a disposed at the lower end of the body portion. In the spacer main body 81, an accommodation space portion 81b formed downward from the upper surface of the spacer main body 81 is provided corresponding to the shape and size of the click member 90.

[0082] The accommodation space portion 81b of the present embodiment is formed in a columnar shape in which the cross-section orthogonal to the vertical direction is circular, and is formed to accommodate the click member 90 and hold it in a posture in which the central axis of the click member 90 is along the vertical direction. Further, the accommodation space portion 81b is formed in a size such that when the click member 90 is inserted into the accommodation space portion 81b and held by the spacer main body 81, a part of the click member 90 protrudes upward from the spacer main body 81.

[0083] The bottom surface portion 81a of the spacer main body 81 is formed to be elastically deformable by receiving a pressing force from the click member 90 when the click member 90 held in the accommodation space portion 81b is pressed downward. Further, the bottom surface portion 81a of the spacer main body 81 can elastically return to its original shape before receiving the pressing force when the pressing force from the click member 90 is released. Particularly in the wind direction adjusting device of the present Example 2, as described above, since the deformation promoting hole portion 76 is provided in the support base portion 72 of the dial support portion 71, when the bottom surface portion 81a of the spacer main body 81 receives a pressing force from the click member 90, the bottom surface portion 81a can be easily and smoothly elastically deformed.

[0084] The sliding contact flange portion 82 of the spacer member 80 extends radially outward from the upper end portion of the spacer main body 81. The sliding contact flange portion 82 has a donut shape when the spacer member 80 is viewed from above, and has a flat upper surface and a lower surface orthogonal to the vertical direction. The sliding contact flange portion 82 is formed with a constant thickness (dimension in the vertical direction) from the upper surface to the lower surface of the sliding contact flange portion 82.

[0085] On the upper surface of the folding contact flange portion 82, two folding contact protruding portions 63 of the dial portion 61 are in contact from above. Further, when the dial portion 61 is rotated, the folding contact flange portion 82 can bring the lower ends of the two folding contact protruding portions 63 into sliding contact with the upper surface of the folding contact flange portion 82, thereby generating an operating load when the dial portion 61 is operated.

[0086] In the second embodiment, by changing at least one of the number and length of the folding contact protruding portions 63 provided on the dial portion 61, changing the thickness of the folding contact flange portion 82, changing the shape and size of the spacer member 80, etc., the magnitude of the operating load generated when the operation dial 60 is operated can be easily adjusted.

[0087] The click member 90 is formed of a synthetic resin harder than the spacer member 80. The click member 90 has a click body portion 91 having a cylindrical shape, and a click upper end portion 92 and a click lower end portion 93 having a hemispherical or substantially hemispherical shape. The click member 90 of the second embodiment is substantially formed in the same manner as the click member 50 of the first embodiment described above, although the sizes of the respective portions are different. In the wind direction adjusting device of the second embodiment, the click upper end portion 92 of the click member 90 contacts the slide surface 64 of the dial portion 61, and the click member 90 is held by the spacer member 80 in a state where the bottom surface portion 81a of the spacer body portion 81 is slightly elastically deformed.

[0088] The click member 90 is held by the spacer member 80 so as to be able to move up and down along the vertical direction from the position of the click member 90 shown in FIGS. 5 and 7 by utilizing the elasticity of the spacer member 80 (particularly, the bottom surface portion 81a). Further, the click member 90 held by the spacer member 80 can bring the click upper end portion 92 into sliding contact with the slide surface 64 of the dial portion 61 when the dial portion 61 is rotated.

[0089] When the click member 90 moves from one side to the other side in the circumferential direction of the click convex portion 65 protruding from the slide surface 64, it is pushed downward by the click convex portion 65, and thus once retracts (descends) into the fixing portion 75 of the spacer member 80. Then, after getting over the click convex portion 65, it pops out (ascends) due to the elastic force of the bottom surface portion 81a of the spacer member 80, and thus makes a movement of hitting against the slide surface 64.

[0090] Thereby, the click member 90 can smoothly get over the click convex portion 65. Also, similar to the case of the aforementioned Embodiment 1, a click feeling can be generated by a change in load when the click member 90 gets over the click convex portion 65, and further, a click sound can be generated when the click member 90 hits against the slide surface 64.

[0091] In this Embodiment 2, at least one of changing the shape and size of the click member 90 (particularly, the click upper end portion 92), changing the shape and size of the click convex portion 65, changing the shape of the spacer main body portion 81 and the thickness of the bottom surface portion 81a of the spacer main body portion 81, and changing the shape and size of the deformation promoting hole portion 76 provided in the dial support portion 71, etc. is performed, so that the magnitude of the load of the click feeling generated when the click member 90 gets over the click convex portion 65, the degree of change in the load of the click feeling, and the magnitude of the click sound, etc. can be easily adjusted.

[0092] In the wind direction adjusting device of this Embodiment 2 as described above, between the dial portion 61 and the dial support portion 71, the spacer member 80 is fixed to the dial support portion 71 in a state of being in contact with the two sliding contact protruding portions 63 of the dial portion 61 as described above. Thereby, when the operation dial 60 is operated to rotate the dial portion 61, an appropriate operation load can be stably generated by the frictional force between the sliding contact flange portion 82 of the spacer member 80 and the two sliding contact protruding portions 63 of the dial portion 61.

[0093] Furthermore, in the wind direction adjusting device of the second embodiment, when the dial portion 61 rotates and reaches a predetermined position, the click member 90 that is held by the spacer member 80 so as to be able to move up and down can overcome the click convex portion 65 provided on the slide surface 64 of the dial portion 61 as described above, thereby generating a click feeling and a click sound.

[0094] That is, in the wind direction adjusting device of the second embodiment, similar to the wind direction adjusting device 1 of the first embodiment described above, both the operation load and the click feeling when operating the operation dial 60 can be generated without using a plunger as in a conventional wind direction adjusting device. Further, by eliminating the need for a plunger, advantages such as miniaturizing the wind direction adjusting device, reducing the number of parts of the wind direction adjusting device, and reducing the manufacturing cost can be obtained. Furthermore, also in the second embodiment, similar to the wind direction adjusting device 1 of the first embodiment described above, it is possible to easily set the presence or absence of the click feeling and the click sound depending on whether or not the click member 90 is installed.

[0095] Note that also in the second embodiment, a wind direction adjusting device may be formed by changing the shape, structure, size, etc. of the click member 90 and / or the spacer member 80. For example, as one of the modified examples of the second embodiment (the third modified example), for example, a wind direction adjusting device may be formed by eliminating the sliding contact flange portion 82 from the spacer member 80 (see FIG. 6) of the second embodiment and using a columnar spacer member having a diameter larger than that of the spacer main body portion 81 of the second embodiment.

[0096] Further, the dial portion 61 may be formed to generate an operation load by directly sliding the lower surface of the dial main body portion 62 on the spacer member 80, for example, without including two sliding contact protrusions 63.

[0097] In the wind direction adjusting device of the above-described Example 2, an operating load is generated by bringing the two sliding protrusions 63 provided on the dial portion 61 into sliding contact with the upper surface of the spacer member 80 (particularly, the upper surface of the sliding contact flange portion 82). However, in the present invention, as another modification example (fourth modification example) of Example 2, at least one sliding contact protrusion or sliding contact wall portion is provided on the dial portion 61, and the operating load is generated by bringing the sliding contact protrusion or sliding contact wall portion into sliding contact with the side surface of the spacer member (for example, the side surface of the sliding contact flange portion). Thus, the wind direction adjusting device may be formed.

[0098] Furthermore, as still another modification example (fifth modification example) of Example 2, instead of using the click member 90 shown in FIG. 6, a mushroom-shaped click member including a conical or pyramidal click upper end portion and a click shaft portion extending downward in a columnar shape from the central portion of the click upper end portion is used, or a click member 90 of Example 2 having an oval or capsule shape is used, and a flange portion extending radially outward from the click body portion 91 is further provided. Thus, the wind direction adjusting device may be formed.

[0099] Also, in the above-described Example 2, the spacer member 80 is engaged and attached to the fixing portion 75 provided on the dial support portion 71 as described above. However, in the present invention, the spacer member 80 may be directly fixed to a part of the dial support portion 71 by, for example, adhesion or welding.

[0100] Furthermore, in the present invention, the operation dial 60 may be provided so as to be operated when rotating the horizontal fins instead of the vertical fins. Also, the spacer member 80 and the click member 90 are fixed to the dial portion 61, and the sliding contact protrusion 63, the slide surface 64, and the click convex portion 65 are provided on the dial support portion 71. Thus, the wind direction adjusting device may be formed.

[0101] Even in the wind direction adjusting device according to the modification example of the second embodiment as described above, an operating load can be generated when the operation dial 60 is operated, and a click feeling and a click sound can be generated when the operation dial 60 is rotated to a predetermined position. Further, in these cases, it is possible to generate a click feeling with a different touch from that of the second embodiment, and a click sound with a different volume and / or pitch from that of the second embodiment.

[0102] Note that the present invention is not limited to the above-described first and second embodiments, and various modifications are possible within the scope having a configuration substantially the same as the configuration described in the claims of the present invention and exhibiting the same operational effects.

[0103] For example, in the above-described first and second embodiments, the case where the wind direction adjusting unit that adjusts the wind direction of air is a vertical fin whose rotation is operated by an operation knob or an operation dial has been described. However, in the present invention, the wind direction adjusting unit is not limited to a rotating fin such as a vertical fin that adjusts the wind direction in the left-right direction or a vertical fin that adjusts the wind direction in the up-down direction as in the first and second embodiments. The wind direction adjusting unit of the present invention includes, for example, a valve such as a shut-off valve that opens and closes the ventilation path (for example, the air flow path in the case body) of the wind direction adjusting device. Even in a wind direction adjusting device in which the rotation of such a valve such as a shut-off valve is operated by an operation unit (for example, a valve operation dial or the like), when the present invention is applied to the wind direction adjusting device, both the operating load and the click feeling when operating the operation unit can be stably generated with a simple structure.

[0104] Also, in the above-described first and second embodiments, the promoting structure for promoting the deformation of the spacer members 40 and 80 is formed by a concave portion (the deformation promoting concave portion 35 provided at the front end portion 32 of the knob in the first embodiment) or a hole portion (the deformation promoting hole portion 76 provided at the fixing portion 75 in the second embodiment). However, in the invention, the promoting structure for promoting the deformation of the spacer member may be formed by a convex portion having a protruding shape.

[0105] For example, in the slide wall portion 12 of Example 1, instead of installing the click convex portion 13 shown in FIG. 4, as described above, when a click concave portion having a shape recessed from the front wall surface of the slide wall portion 12 is installed, on the front end portion 32 of the knob in Example 1, in order to promote the deformation of the spacer member 40, instead of providing the deformation promoting concave portion 35, it is preferable to provide a deformation promoting convex portion protruding rearward from the rear end surface of the front end portion 32 of the knob.

[0106] When the click concave portion as described above is provided in the wind direction adjusting device, the click member 50 is in contact with the slide wall portion 12 strongly pressed by the spacer member 40, and when the operation knob 30 moves and the click member 50 enters the click concave portion of the slide wall portion 12, it is possible to generate a click feeling and a click sound. At this time, if a deformation promoting convex portion is provided on the front end portion 32 of the knob, the deformation of the spacer member 40 can be promoted by the deformation promoting convex portion, and a part of the click member 50 can be easily made to enter the click concave portion of the slide wall portion 12.

[0107] Furthermore, in the present invention, the position, structure, and means for fixing or holding the elastic members (spacer members 40, 80), the position, shape, and structure of the sliding contact portions (the horizontal fins 10 in Example 1 and the sliding contact protruding portions 63 in Example 2) with which the elastic members are in sliding contact, and the position, shape, and structure of the portions (the slide wall portion 12 in Example 1 and the slide surface 64 in Example 2) with which the click members 50, 90 are in sliding contact, etc. are not limited to the wind direction adjusting devices of Example 1 and Example 2 described above, and can be appropriately changed in consideration of the size and layout of the wind direction adjusting device, and the operability of the operation portion, etc.
