Description

  The present invention relates to a register mainly used for air blowing adjustment of an air conditioner such as an automobile, and more particularly to a round register having a cylindrical retainer and a substantially circular air outlet.

  2. Description of the Related Art Conventionally, as a round register having a circular air outlet, a register provided with a round turning louver that can be turned around a central axis in a blowing direction in a cylindrical frame is disclosed in Patent Document 1 below. Is known by.

Japanese Utility Model Publication 3-27237

  This register has a cylindrical outer frame having a spherical surface inside, and an inner frame having an outer spherical surface is fitted inside the outer frame so as to be able to rotate and tilt, and there are four movable pieces in the inner frame. A rotating louver is arranged in which the blades are radially arranged around the central axis, and each movable blade of the rotating louver is rotatably supported around a radial support shaft of the inner frame. .

  Further, this register is provided with a bevel gear at the end of the central shaft and the inner end of the support shaft of each movable blade, and the bevel gear provided at the end of the central shaft meshes with the bevel gear of each movable blade, and is provided at the tip of the central shaft. When the knob is turned, each movable blade rotates about its support shaft through a bevel gear.

  When using the register, if the knob at the tip of the central shaft is turned, the four movable blades rotate about the radial support shaft via the bevel gear, and the four movable blades are parallel to the blowing direction. The air blown from the air outlet is converged to the center by the movable blades, but when the four movable blades are tilted about the respective support shafts, the blown air flow is diffused around the air outlet. To flow. Further, when each movable blade is rotated to a state parallel to the cross section of the flow path, the flow path of the register is shut off to stop air blowing.

  However, when changing the wind direction, the conventional register tilts (rotates) the inner frame in any direction such as up / down / left / right with respect to the outer frame with the knob, and the movable louver tilts together with the inner frame, The wind direction is adjusted. At this time, the inner frame that tilts (rotates) with respect to the outer frame rotates with its outer spherical surface contacting the inner spherical surface of the outer frame with a relatively large area.

  In a register in which a part is molded by plastic molding, there is usually an error within tolerance in the dimension of each part for each product, and in the structure of the movable louver of the register that is supported rotatably by spherical contact, Variations in frictional resistance during rotation occur due to dimensional error within tolerance of each spherical shape for each register product.

  For this reason, when the gap between the outer frame and the inner frame is relatively large and the frictional resistance between them is small, the tilting operation of the inner frame becomes too light, and the direction of the inner frame is likely to change due to the wind pressure during blowing, On the other hand, when the gap between the outer frame and the inner frame is small and the frictional resistance between them is large, the tilting operation of the inner frame becomes heavy and the operation load is not constant.

  In addition, the conventional register can adjust the air flow from convergence to diffusion by rotating the four movable blades around the support shaft in the radial direction. There is a demand for a smooth diffused air.

  This invention solves the above-mentioned subject, and aims at providing the round-shaped register which can ventilate smooth diffused wind, and can improve the feeling of operation at the time of tilting operation. To do.

In order to achieve the above object, in the register of the present invention, a rotating louver having a cylindrical frame is rotatably disposed in a cylindrical retainer, and the rotating louver has a center line parallel to the blowing direction. In a register in which a plurality of movable fins are rotatably supported by a radial support shaft inside the cylindrical frame from
A ball joint having a ball is disposed on a center line parallel to the air blowing direction in the retainer, and a central shaft support portion in which a plurality of shaft support portions are provided radially at the center of the cylindrical frame is provided in the rotating louver. The central shaft support portion can be tilted by fitting the ball hole provided in the inner portion to the ball while at least the inner portion is formed of a polymer elastic body. Attached,
A plurality of movable fins are rotatably supported on the inner side of the cylindrical frame by radial support shafts at substantially equal intervals, and the inner portions of the movable fins correspond to the shaft support portions of the central shaft support portion. Is pivotally supported by
An operation unit is rotatably mounted around the center line of the rotation louver at the center of the front side of the central shaft support unit, and the operation unit is linked to an inner portion of each movable fin via a bevel gear mechanism.
When the operation portion is rotated around the center line, the movable fin is rotated around the shaft support portion of the outer peripheral portion of the central shaft support portion via the bevel gear mechanism, and the operation portion is moved to the When the cylindrical frame is moved in the radial direction, the rotating louver is tilted about the ball of the ball joint.

  According to the present invention, when the rotation louver is tilted in an arbitrary direction by holding the central operation portion of the rotation louver, the rotation louver tilts around the ball joint ball supported at the center. The wind direction can be changed by tilting the rotating louver with a stable and smooth operation feeling.

  In addition, since at least the inner part of the central shaft support part is formed of a polymer elastic body and the ball of the ball joint is fitted in the ball hole and rotated, the tilting operation of the rotating louver and the rotating operation of the movable fin are performed. An appropriate operation load is applied, and the rotation louver can be tilted or the movable fin can be rotated with a stable operation load and a smooth operation feeling.

  Here, in the register, five shaft support portions are provided radially at equal intervals on the outer periphery of the central shaft support portion of the rotating louver, and the inner support shafts of the five movable fins are respectively the shaft support portions. The movable fins are arranged at equal intervals inside the cylindrical frame of the rotating louver, and the movable fins rotate to a state substantially parallel to the transverse cross section of the cylindrical frame. It can be configured to close the inside. According to this, compared with the size of the four movable blades used in the conventional register, the size of the movable fin can be made smaller, thereby causing the movable fin to interfere with the ball joint. Without rotating, the rotating louver can be tilted.

  That is, for example, when four movable fins are pivotally supported around the central shaft support portion as in a conventional register, when the movable fins are pivoted to a state substantially parallel to the transverse cross section of the cylindrical frame, When the movable louver is tilted in a state where the movable fin is parallel to the air blowing direction, the movable fin is movable as compared with the case of five movable fins. The rear inner side of the fin interferes with the ball joint, and the tilt angle of the rotating louver is limited.

  In contrast, by providing the movable louver with five movable fins, the movable fin becomes smaller in size and avoids interference with the ball joint when the rotational louver is tilted. Can be tilted. In addition, the length of the retainer can be further shortened because the axial length in a state parallel to the axial direction (air blowing direction) of the flow path can be shortened with the miniaturization of the movable fin. Thereby, the installation space of the register can be saved.

  Further, the bevel gear mechanism is configured such that a drive-side bevel gear member and a driven-side bevel gear piece mesh with each other, and the bevel gear member is rotatable at the front portion of the central shaft support portion in the cylindrical frame of the rotation louver. The driven bevel gear piece may be integrally formed in the vicinity of the inner support shaft of each movable fin. According to this, since the bevel gear piece on the driven side is integrally formed with the inner portion of each movable fin, the number of parts can be reduced and the number of assembling steps for the parts can be reduced.

  Further, the cylindrical frame of the rotating louver is formed by fitting a front cylindrical frame and a rear cylindrical frame, and the front cylindrical frame is provided with a lattice portion along a transverse section thereof, and at the center of the lattice portion. A shaft portion of the operation portion is rotatably inserted into an insertion hole of the provided operation portion holding portion, and the shaft portion of the operation portion is attached to a central shaft portion of the bevel gear member of the bevel gear mechanism together with a locking claw. It can be set as the structure connected by fitting. According to this, the operation portion can be securely attached to the center of the front cylindrical frame without rattling, and the bevel gear member can be prevented from coming off.

  Each movable fin of the rotating louver is provided with an outer support shaft, and the outer support shaft is sandwiched between the front cylindrical frame and the rear cylindrical frame and is rotatably supported. Can do.

  Further, an inner support shaft projects from the inside of each movable fin of the rotating louver, and the inner support shaft is rotatably inserted into the shaft hole of the shaft support portion provided on the outer peripheral portion of the central shaft support portion. Can be configured.

  Further, if the shaft support portion and the inner portion of the central bearing portion are integrally formed of a polymer elastic body, the number of parts can be reduced compared to the case where a load applying member is provided separately from the shaft support portion. In addition, the man-hours for assembling parts can be reduced.

  On the other hand, for the central bearing portion, the shaft support portion can be formed of a hard synthetic resin, and the inner portion can be formed of a polymer elastic body as a soft elastic bearing portion. It is molded with resin, and the support of the movable fin is properly supported, and the softness and elasticity of the polymer elastic body of the soft elastic bearing are arbitrarily selected. An operational feeling can be obtained.

  According to the register of the present invention, smooth diffused air can be blown, a smooth tilting operation can be performed, the feeling of operation feeling during the tilting operation can be improved, and rattling can be prevented.

As shown in FIGS. 8, 9, and 16, the ball joint 8 is provided with a ball 81 at the front end of the shaft portion 82, and the ball 81 has a central shaft support portion 3 positioned at the center of the rotating louver 2. A central ball hole 32 (FIGS. 5, 14, and 16) is fitted around and attached so as to be tiltable and rotatable.

  In particular, the central shaft support portion 3 is integrally formed from a polymer elastic body such as a thermoplastic elastomer, and as shown in FIGS. 13 to 15, the ball hole 32 provided at the rear end portion and the outer peripheral portion thereof are equiangularly spaced. The shaft holes 42 of the shaft support portions 4 that are radially arranged support the balls 81 of the ball joint 8 and the support shafts 27 inside the five movable fins 23 so as to be able to rotate while giving a good operation load. It has a structure.

  That is, the ball 81 of the ball joint 8 is fitted into the ball hole 32 at the center of the central shaft support portion 3 made of a polymer elastic body, and five shaft support portions 4 provided radially on the outer periphery of the central shaft support portion 3.

Further, the support shaft 27 inside each movable fin 23 is supported with a suitable frictional resistance in the shaft hole 42 of the shaft support portion 4 of the central shaft support portion 3, and the inner shaft portion 54 is interposed at the front portion of the central shaft support portion 3. The bevel gear member 51 that is supported and rotated by the operation of the operation portion 6 generates an appropriate frictional resistance with the shaft hole 31a of the central shaft support portion 3, thereby providing an adjustable appropriate operation load to the operation portion 6. Can be granted.

  That is, as shown in FIGS. 8, 10, and 16, the central shaft 31 at the front portion of the central shaft support portion 3 is provided with the shaft hole 31 a, and the inner shaft portion 54 of the bevel gear member 51 rotates to the shaft hole 31 a. The shaft portion 61 of the operation portion 6 is inserted into the shaft portion 52 at the front portion of the bevel gear member 51.

  For this reason, when the user turns the operation unit 6 to open and close the rotation louver 2, the bevel gear member 51 is rotated, and the movable fin 23 is rotated around the support shafts 24 and 27. An operation load is generated, and the movable fin 23 can be rotated around the support shafts 24 and 27. Further, as shown in FIG. 18, when the orientation of the turning louver 2 is changed by tilting or turning by holding the operation portion 6, an appropriate operation load is applied between the ball 81 and the ball hole 32 of the central shaft support portion 3. Thus, the rotating louver 2 can be swung left and right and up and down.

  As shown in FIGS. 4, 8, and 10, the operation unit 6 is formed in a dial knob shape, and is attached to the center of the lattice portion 21 a at the front portion of the cylindrical frame 20 of the rotation louver 2 so as to be rotatable. . As shown in FIGS. 8 and 16, an operation portion holding portion 21b is formed as a circular recess at the center of the lattice portion 21a, and an insertion hole 21c is provided at the center of the operation portion holding portion 21b. The shaft portion 61 of the operation portion 6 is inserted into the insertion hole 21c from the front portion, and the shaft portion 52 of the bevel gear member 51 is inserted into the shaft portion 61 of the operation portion 6 from the rear portion. The locking claw 53 is locked to the locking portion 62 of the shaft portion 61, and the operation portion 6 and the bevel gear member 51 are connected so as to be rotatable and attached to the center of the cylindrical frame 20.

  As shown in FIGS. 5, 10, and 16, the operation portion 6 is inserted into the operation portion holding portion 21 b and the shaft portion 61 is inserted into the insertion hole 21 c, and the locking claw 53 of the bevel gear member 51 is attached to the operation portion 6. Since it is locked to the locking portion 62 of the shaft portion 61, the operation portion 6 can be pivotably attached without rattling, and the bevel gear member 51 of the bevel gear mechanism 5 is centered by the rotation operation of the operation portion 6. The movable fins 23 are rotated with respect to the shaft support portion 3 and are radially arranged on the outer peripheral portion of the central shaft support portion 3 to rotate about the support shafts 24 and 27. As shown in FIGS. 3 and 4, the operation portion 6 is provided so as to protrude slightly forward from the air outlet 9 b of the bezel 9, so that the user can easily hold the operation portion 6 and tilt it when in use. Or it can be turned.

  The bevel gear member 51 of the bevel gear mechanism 5 rotates about the central shaft 31 of the central shaft support portion 3. As shown in FIGS. 4 and 5, the bevel gear member 51 is pivotally supported on each shaft support portion 4 extending radially from the central shaft support portion 3. A bevel gear piece 25 provided at the inner end of each movable fin 23 meshes with the bevel gear member 51. Therefore, when the operation unit 6 is rotated, the bevel gear piece 25 is driven and rotated via the bevel gear member 51, and each movable fin 23 of the rotation louver 2 rotates about its support shafts 24 and 27. Move. That is, as shown in FIG. 10, the bevel gear mechanism 5 is configured by meshing the driving-side bevel gear member 51 and the driven-side bevel gear piece 25, and the driving-side bevel gear member 51 has a shaft portion 52 projecting at its center. The shaft portion 52 is connected to the center of the operation portion 6. The shaft portion 52 is inserted into the insertion hole 21c of the operation portion holding portion 21b provided at the center of the lattice portion 21a of the front cylindrical frame 21, and is rotatably supported.

  Further, as shown in FIGS. 11 and 16, an inner shaft portion 54 is provided on the rear portion (back side) of the bevel gear mechanism 5 of the bevel gear mechanism 5, and the inner shaft portion 54 is formed on the central shaft support portion 3. The shaft is inserted into the shaft hole 31a of the central shaft 31 so as to be rotatable. Further, the shaft portion 52 at the front portion of the bevel gear member 51 is fitted into the shaft hole of the shaft portion 61 of the operation portion 6, and the locking claw 53 of the shaft portion 52 is locked to the locking portion 62 of the shaft portion 61. . Accordingly, the drive-side bevel gear member 51 is rotatably supported by the central shaft 31 of the central shaft support portion 3 and is connected to the shaft portion 61 of the operation portion 6. In this way, the locking claw 53 of the bevel gear member 51 is locked to the locking portion 62 of the shaft portion 61 of the operation portion 6, the operation portion 6 is inserted into the operation portion holding portion 21b, and the shaft portion 61 is inserted. Since it is inserted into the hole 21c, the operation portion 6 is attached to the center position of the rotation louver 2 so as to be rotatable with an appropriate operation load without rattling.

  On the other hand, as shown in FIGS. 10 and 12, the movable fin 23 of the rotating louver 2 is composed of five fins, and the inner side of each movable fin 23 has a driven side that meshes with the drive-side bevel gear member 51. The bevel gear piece 25 is integrally formed, and a support shaft 27 is projected at the center position of the inner shaft. Each movable fin 23 is supported by inserting an inner support shaft 27 provided on the inner side thereof into a shaft hole 42 of the shaft support portion 4 of the central shaft support portion 3, and the bevel gear piece 25 is a bevel gear member 51 positioned at the front portion thereof. Mesh with. Since the rotation range of each movable fin 23 is set to about 90 °, the bevel gear piece 25 does not need to be formed in the shape of an annular wheel, and as shown in FIG. It is formed as a tooth part. As shown in FIG. 12, a gap closing convex portion 28 protrudes from the base of the fin main body 26 of the movable fin 23, and a gap that tends to occur in the vicinity of the fin base when the movable fin 23 is closed is formed. I try to close it.

  With the above configuration, when the drive-side bevel gear member 51 is rotated by the operation portion 6, each driven-side bevel gear piece 25 rotates within a range of about 90 ° around the shaft support portion 4. The shaft 15 is rotated from the state parallel to the center line S2 of the rotation louver 2 to the state parallel to the vertical plane perpendicular to the center line S2, and the flow path 15 is closed as shown in FIG. The Rukoto. Further, as described above, when the operation louver 2 is tilted in any direction such as up, down, left and right as shown in FIG. Tilt or rotate in an arbitrary direction while being supported by only 8.

  As described above, the rotating louver 2 includes five movable fins 23, and the shaft support portions 4 are provided radially on the outer peripheral portion of the central shaft support portion 3. The support shaft 27 inside the movable fin 23 is fitted and supported, and the five movable fins 23 are disposed radially inside the cylindrical frame 20 at substantially equal intervals (an angular interval of about 72 degrees). The Further, each movable fin 23 sandwiches a support shaft 24 protruding outward in the radial direction between the front cylindrical frame 21 and the rear cylindrical frame 22 of the cylindrical frame 20. As a result, each movable fin 23 is pivotally supported about the inner and outer support shafts 24 and 27 extending radially in the outer peripheral direction of the central shaft support portion 3.

  In such a rotating louver 2, when each movable fin 23 is rotated around its support shafts 24, 27, the fin body 26 of the movable fin 23 is substantially the same as the cross section of the cylindrical frame 20 at the rotation end. The parallel state is established, the flow path 15 is fully closed, and air flow is blocked. Therefore, the fin main bodies 26 of the five movable fins 23 are formed in a shape and size that can be fully closed when they are juxtaposed on a cross section perpendicular to the ventilation direction of the flow path 15.

  In other words, when the rotating louver 2 rotates the five movable fins 23 to the state parallel to the cross section perpendicular to the airflow direction, the movable fins 23 have a shape and size that make the flow path 15 fully closed. Is formed. Since the rotating louver 2 has five movable fins 23 arranged side by side, the size of the fin main body 26 of the movable fin 23 can be made smaller than in the case of four movable fins. Thereby, the rotation louver 2 can be tilted to a predetermined maximum angle without causing the movable fin 23 to interfere with the ball joint 8 when tilting in the vertical and horizontal directions.

  In addition, when the number of the movable fins 23 of the rotating louver 2 is five, when the movable fins 23 are rotated about the support shafts 24 and 27 to diffuse the air flow, the four movable fins 23 as in the prior art are used. Compared to the rotating louver provided with fins, the wind is diffused at a higher efficiency than when the air is blown, and the mild wind diffused efficiently can be blown around the air outlet. .

  Furthermore, as described above, with the downsizing of the movable fin 23, the length in the axial direction in a state where the movable fin 23 is parallel to the axial direction (air blowing direction) of the flow path 15 can be shortened. For this reason, the length of the retainer 1 can be made shorter than that of the conventional register of four movable fins, so that the space for installing the register can be saved.

  When assembling the rotating louver 2 having the above-described configuration, as shown in FIGS. 10 and 16, the operating portion 6 is inserted into the operating portion holding portion 21b of the front portion of the front cylindrical frame 21, and the shaft portion 61 is inserted into the insertion hole 21c. The shaft portion 52 of the bevel gear member 51 is inserted into the shaft portion 61 of the operation portion 6 from the rear side of the front cylindrical frame 21, and the locking claw 53 is locked to the locking portion 62. As a result, the operation unit 6 and the bevel gear member 51 are securely assembled to the central axis position of the front cylindrical frame 21 so that the operation unit 6 and the bevel gear member 51 can be prevented from being loosened. .

  Next, the inner support shaft 27 is inserted into the shaft hole 42 so that the five movable fins 23 are held radially by the shaft support portion 4 on the outer peripheral portion of the center shaft support portion 3. The shaft hole 31 a of 31 is fitted into the inner shaft portion 54 of the bevel gear member 51. In this state, the front cylindrical frame 21 and the rear cylindrical frame 22 are supported so that the outer support shaft 24 of the five movable fins 23 is sandwiched and supported by the bearing portion between the front cylindrical frame 21 and the rear cylindrical frame 22. The engaging claw 22a and the engaging portion 21d are engaged with each other.

The turning force is transmitted to the five movable fins 23 via the bevel gear piece 25, and the movable fins 23 are rotated about the support shafts 24 and 27, so that the flow path in the cylindrical frame 20 is opened and closed. The

  The ball 81 of the ball joint 8 is inserted into the ball hole 32 in the rear portion of the central shaft support portion 3 with respect to the rotating louver 2 assembled in this way, and in this state, as shown in FIGS. The shaft portion 82 of 8 is inserted into the ball joint support portion 11 in the retainer 1, and the bezel 9 is fitted into the front portion of the retainer 1 so as to cover the front portion of the rotating louver 2. At this time, the guide convex portion 22b protruding from the outer peripheral portion of the rear cylindrical frame 22 of the cylindrical frame 20 enters the guide groove 1a (FIG. 9) provided in the front inner peripheral portion of the retainer 1, and further guide convex portions. 22b can also enter the guide groove 9d of the bezel 9 (FIG. 9d). The locking claw 9a of the bezel 9 is locked to the locking portion 13 of the retainer 1, and the assembly of the register is completed.

  In this register, a rotating louver 2 provided with a cylindrical frame 20 and a movable fin 23 is housed and supported in a retainer 1 so as to be rotatable by a ball joint 8, and a bezel 9 is fitted to the front thereof. The cylindrical frame 20 of the rotating louver 2 is supported in the retainer 1 so as to be rotatable in a non-contact manner with a slight gap between the outer peripheral surface thereof and the inner peripheral surface of the retainer 1. For this reason, when the rotation louver 2 is tilted, it can be tilted smoothly. However, when air is blown, leakage air is introduced into a slight gap generated between the outer peripheral surface of the cylindrical frame 20 and the inner peripheral surface of the retainer 1. Current may flow. In such a case, as shown in FIGS. 5 and 7, if a nonwoven fabric sheet 29 is interposed in the gap between the outer peripheral surface of the rear cylindrical frame 22 and the inner peripheral surface of the retainer 1, the leakage air flow can be reduced. Can do.

  The register having the above-described configuration is used by being mounted on, for example, an air outlet of an air conditioner provided on an instrument panel of an automobile. When changing the blowing direction of the register, the rotation louver 2 is tilted or rotated by holding the operation unit 6. Since the operation unit 6 is formed in a dial shape and is disposed so as to protrude slightly forward from the air outlet 9b of the bezel 9, the user can easily hold the operation unit 6 and perform tilting operation or rotation operation. .

  As shown in FIGS. 2 and 4, when the rotating louver 2 is in a straight state in front of the register, that is, the movable fin 23 of the rotating louver 2 is connected to the center line S2 along the axial direction of the flow path 15. When in a parallel state, the airflow is guided by the movable fins 23 of the rotating louver 2 and blown straight forward, and at this time, the airflow is concentrated in a relatively narrow range in front.

  On the other hand, when the air is diffused and blown over a relatively wide range around the front of the air outlet 9b, the operation unit 6 is held and turned to the right or left so as to twist the center line S2.

  At this time, the rotational force of the operation unit 6 is transmitted to the bevel gear member 51 via the shaft portion 52 of the bevel gear mechanism 5, the bevel gear member 51 rotates, and the rotation of the five movable fins 23 that mesh with the bevel gear member 51. Transmitted to the bevel gear piece 25, the five movable fins 23 rotate about the support shafts 24 and 27, and the fin body 26 of each movable fin 23 has a radial axis along the cross section of the flow path 15. Rotate around to tilt back and forth.

  As a result, when the air flow passes through the rotation louver 2, the air flow is widened and blown around the center line S2 of the rotation louver 2, and diffused around the air outlet 9b. Be blown. At this time, since the air is guided and diffused by the five movable fins 23 arranged inside the air outlet, a milder wind is generated compared to the case of the conventional four movable fins. Can blow.

  On the other hand, in order to block the blowing, the operation unit 6 is further rotated to the right or left to the rotation end. Accordingly, as shown in FIG. 17, each movable fin 23 of the rotating louver 2 is in a state parallel to a vertical plane perpendicular to the center lines S1 and S2 (flow channel blocking state) with the support shafts 24 and 27 as axes. ), The flow path 15 is fully closed, and the air flow is blocked.

  On the other hand, when the wind direction is directed obliquely upward, when the operation unit 6 is lifted up, the rotating louver 2 including the operation unit 6 is centered on the ball 81 of the ball joint 8 as shown in FIG. The center line S2 of the rotating louver 2 is tilted upward as shown in FIG. 18 (a) with respect to the center line S1 of the retainer 1, and thereby the blowing direction is directed obliquely upward. . At this time, the guide convex portion 22b on the outer peripheral portion of the cylindrical frame 20 moves smoothly while being guided in the guide grooves 1a and 9d, and the front cylindrical frame 21 or the rear cylindrical frame 22 is operated when the rotary louver 2 is rotated. When the edge portion of the contact portion comes into contact with the contact portion 9c in the retainer 1 or the bezel 9, the operation stops. Similarly, when the wind direction is directed obliquely downward and upward, when the operation unit 6 is held and lowered, the rotating louver 2 including the operation unit 6 causes the ball 81 of the ball joint 8 to move as shown in FIG. The center line S2 of the rotating louver 2 is tilted downward as shown in FIG. 18 (b) with respect to the center line S1 of the retainer 1, and the air blowing direction is directed obliquely downward. It is done.

  Further, when the rotating louver 2 is tilted upward or downward as described above and tilted in the left-right oblique direction with the operation unit 6, the cylindrical frame 20 of the rotating louver 2 is moved to the ball joint 8 ball. It rotates in the inclination direction with the axis passing through the center of 81 and passing through the guide convex portion 22b of the outer peripheral portion of the cylindrical frame 20 as the central axis, and the outlet direction of the rotation louver 2 is directed to the left and right oblique directions. .

  Thus, by tilting the operation unit 6 in any direction such as up and down or left and right, the cylindrical frame 20 of the rotation louver 2 can smoothly rotate and the wind direction can be directed in any direction.

  Further, at this time, the tilting operation and the rotating operation by the operation unit 6 of the rotating louver 2 are performed through the central shaft support 3 made of a polymer elastic body, and the rotating louver 2 is connected to the ball joint 8 at the time of the tilting operation. Since the ball hole 32 of the central shaft support portion 3 slides and tilts on the peripheral surface of the ball 81, an appropriate operation load (friction resistance) is generated without rattling, and the tilt operation is performed with a smooth operation feeling. Can do.

  Further, when the operation unit 6 is rotated, the bevel gear member 51 is rotated, and the rotational force is transmitted to the five movable fins 23 via the bevel gear pieces 25. Each movable fin 23 has its support shaft 24, 27, the bevel gear member 51 rotates with its inner shaft portion 54 in sliding contact with the shaft hole 31a of the central shaft 31 of the central shaft support portion 3, and the support shaft 27 of the movable fin 23 is the central shaft. Since the shaft 3 of the support portion 3 slides in the shaft hole 42 and rotates, the operation operation (friction resistance) is generated without rattling and the rotation operation is performed with a smooth operation feeling. can do.

  On the other hand, when the operation unit 6 is further rotated around the center line S2 with the rotation louver 2 tilted as described above, the rotational force of the operation unit 6 is the shaft portion of the bevel gear mechanism 5 as described above. The bevel gear member 51 is transmitted to the bevel gear member 51 through 52, and the bevel gear member 51 rotates, and the rotation is transmitted to the bevel gear pieces 25 of the five movable fins 23 meshing with the bevel gear member 51. The shafts 24 and 27 are rotated about the shaft. As a result, the air flow passing through the rotating louver 2 is concentrated from the state of being blown along the center line S2 to the state of being diffused to the surroundings so as to rotate around the center line S2 of the rotating louver 2. It can change and it can adjust so that a ventilation state may be changed from a concentration state to a diffusion state like the above. Then, when the operation unit 6 is rotated to the limit in the closing direction, as shown in FIG. 17, the five movable fins 23 are rotated until the channel 15 is completely closed, and the channel 15 is closed. Is done.

  As described above, when the rotation louver 2 is tilted in an arbitrary direction by holding the operation portion 6 at the center of the rotation louver 2, the rotation louver 2 is centered on the ball 81 of the ball joint 8 supported at the center. Therefore, the wind direction can be changed by tilting the rotating louver with a stable and smooth operation feeling.

  Further, since the central shaft support portion 3 is integrally formed of a polymer elastic body and the ball 81 of the ball joint 8 is fitted into the ball hole 32 and rotated, the tilting operation of the rotating louver 2 and the movable fin 23 At the time of the rotation operation, an appropriate operation load is applied, and the rotation louver 2 can be tilted or the movable fins 23 can be rotated with a stable operation load and a smooth operation feeling.
