Description

本発明は、主に自動車などの空調装置の空気吹出調整用に使用されるレジスタに関し、特に円筒状のリテーナと略円形の空気吹出口を有する丸型のレジスタに関する。   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.

従来、円形の空気吹出口を有する丸型のレジスタとして、円筒フレーム内に送風方向に沿った中心軸の回りで回動可能な丸型の回動ルーバーを備えたレジスタが、下記特許文献１などにより知られている。   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.

実公平３−２７２３７号公報Japanese Utility Model Publication 3-27237

このレジスタは、内側に球面を有する円筒形の外枠を有し、その外枠の内側に、外側球面を有する内枠を、回動及び傾動可能に嵌め込み、内枠内には４枚の可動羽根を中心軸の周囲に放射状に配置した回動ルーバーが配設され、回動ルーバーの各可動羽根は、内枠のラジアル方向の支軸の回りで回動可能に軸支されて構成される。   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. .

さらに、このレジスタは、中心軸の末端及び各可動羽根の支軸の内側端にベベルギヤが設けられ、中心軸の末端に設けたベベルギヤと各可動羽根のベベルギヤが噛合し、中心軸の先端に設けた摘みを回すと、ベベルギヤを介して各可動羽根がその支軸を軸に回動する構造となっている。   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.

レジスタの使用時、中心軸先端の摘みを回すと、ベベルギヤを介して４枚の可動羽根がラジアル方向の支軸を中心に回動し、４枚の可動羽根が送風方向と平行な場合、レジスタの空気吹出口から送風される風が、可動羽根によって、中央に収束されるが、４枚の可動羽根が各支軸を軸に傾動すると、送風される空気流は空気吹出口の周囲に拡散するように流れる。さらに、各可動羽根を流路の横断面と平行な状態まで回動させた場合、４枚の可動羽根がレジスタの流路を遮断し送風を止めるようになっている。   When using the register, turning the knob at the tip of the central shaft turns the four movable blades around the radial support shaft via the bevel gear, and if 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 four movable blades block the flow path of the register and stop the blowing.

しかし、この従来のレジスタは、可動羽根を流路の横断面と平行な状態まで回動させて流路を閉鎖した際、可動羽根の外周縁部と円筒外枠の内周部との間に、隙間が生じやすく、製品ごとの各部品寸法の公差内誤差によりその隙間が大きく生じた場合、閉鎖時に空気流が隙間から漏れて送風され、流路閉鎖時の風漏れが課題となっていた。   However, when the movable blade is rotated to a state parallel to the cross section of the flow path to close the flow path, this conventional register is located between the outer peripheral edge of the movable blade and the inner peripheral portion of the cylindrical outer frame. , Gaps are likely to occur, and if the gaps are large due to tolerance within each part size for each product, the air flow leaks from the gap when closed, and air leakage when the flow path is closed is a problem .

本発明は、上述の課題を解決するものであり、回動ルーバーの可動フィンにより流路を閉鎖したときの風漏れをなくすことができる丸型のレジスタを提供することを目的とする。   The present invention solves the above-described problems, and an object of the present invention is to provide a round register that can eliminate wind leakage when a flow path is closed by a movable fin of a rotating louver.

In order to achieve the above object, the register of the present invention provides:
A rotating louver having a cylindrical frame is rotatably disposed in a cylindrical retainer, and a plurality of movable fins radially extend from the center line parallel to the blowing direction on the rotating louver. In a register that is pivotally supported by a radial spindle,
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 is attached so as to be tiltable and rotatable by fitting a ball hole provided in the center to the ball,
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.
A fin edge is provided along the inner periphery of the cylindrical frame,
When the operation portion is moved in the radial direction of the cylindrical frame, the turning louver is tilted about the ball of the ball joint, and when the operation portion is turned around the center line, the movable louver is moved. When the fin is rotated about the shaft support portion of the outer peripheral portion of the central shaft support portion via the bevel gear mechanism, and the movable fin is rotated to the closed state of the flow path, the outer peripheral edge portion of the movable fin Abuts against the fin abutting edge of the cylindrical frame ,
A gap closing rib for closing the gap when the movable fin closes the flow path is provided on the outer peripheral portion of the central shaft support portion .

この発明のレジスタによれば、回動ルーバーの中央の操作部を持って回動ルーバーを任意の方向に傾動操作したとき、回動ルーバーは、中央に支持されたボールジョイントのボールを中心に傾動するので、安定した滑らかな操作フィーリングで、回動ルーバーを傾動させて風向を変えることができる。   According to the register of the present invention, when the rotary louver is tilted in an arbitrary direction by holding the central operation portion of the rotary louver, the rotary louver tilts around the ball joint ball supported at the center. Therefore, the wind direction can be changed by tilting the rotating louver with a stable and smooth operation feeling.

また、回動ルーバーの可動フィンが流路の閉鎖位置まで回動したとき、可動フィンの外周縁部が円筒フレームの内側のフィン当て縁部に当接するので、可動フィンと円筒フレームの内周部間に生じやすい隙間を閉鎖することができ、回動ルーバーを閉鎖操作した時の風漏れを最小にすることができる。   Further, when the movable fin of the rotating louver is rotated to the closed position of the flow path, the outer peripheral edge of the movable fin abuts on the inner fin contact edge of the cylindrical frame, so that the movable fin and the inner peripheral part of the cylindrical frame It is possible to close gaps that are likely to occur between them, and to minimize wind leakage when the rotating louver is closed.

ここで、上記レジスタにおいて、上記可動フィンが上記流路を閉鎖したとき、隙間を閉じるための隙間閉鎖用リブは、上記軸支部の間を閉じるように、略三角形状に形成することができる。さらに、上記回動ルーバーの各可動フィンの元部近傍に、隙間閉鎖用凸部を設けることができる。これによれば、回動ルーバーの可動フィンの閉鎖操作により、可動フィンが流路を閉鎖したとき、中央軸支部の外周部に生じやすい隙間を隙間閉鎖用リブが閉鎖し、さらに、可動フィンの元部近傍に生じやすい隙間を隙間閉鎖用凸部が閉鎖して、風漏れを一層少なくすることができる。 Here, in the register, when the movable fin closes the flow path, the gap closing rib for closing the gap can be formed in a substantially triangular shape so as to close the space between the shaft support portions. Further, a gap closing convex portion can be provided in the vicinity of the base portion of each movable fin of the rotating louver. According to this, when the movable fin closes the flow path by the closing operation of the movable fin of the rotating louver, the gap closing rib closes the gap that is likely to be generated in the outer peripheral portion of the central shaft support portion. The gap closing convex portion closes the gap that is likely to occur in the vicinity of the base portion, so that wind leakage can be further reduced.

さらに、上記ベベルギヤ機構として、中央軸部及び中央嵌合穴を有するベベルギヤ部材が設けられ、上記中央軸支部は、該ベベルギヤ部材の該中央嵌合穴に嵌合部を嵌入して取り付けられ、該ベベルギヤ部材の前部の中央軸部には前記操作部が嵌着され、該ベベルギヤ部材の該中央嵌合穴の周囲に、該中央軸支部の該嵌合部の外周に接触して支持する支持用リブを設け、該操作部を操作して該中央軸支部を、前記ボールジョイントを中心に傾動させたとき、該中央軸支部の外周部の隙間閉鎖用リブが該支持用リブに当接するように構成することができる。これによれば、操作部を操作して上記回動ルーバーを、上記ボールジョイントを中心に傾動させ、最大制限角度まで傾動させて停止したとき、中央軸支部を傾動させる傾動荷重は支持用リブによって確実に支持され、傾動操作時などに操作部が不安定に傾くなどの不具合をなくすことができる。   Further, as the bevel gear mechanism, a bevel gear member having a central shaft portion and a central fitting hole is provided, and the central shaft support portion is attached by fitting a fitting portion into the central fitting hole of the bevel gear member, The operation portion is fitted on the central shaft portion of the front portion of the bevel gear member, and is supported around the central fitting hole of the bevel gear member and in contact with the outer periphery of the fitting portion of the central shaft support portion. When the operation portion is operated and the central shaft support portion is tilted about the ball joint, the gap closing rib on the outer peripheral portion of the central shaft support portion comes into contact with the support rib. Can be configured. According to this, when the operation unit is operated and the rotation louver is tilted about the ball joint and tilted to the maximum limit angle and stopped, the tilting load that tilts the central shaft support is caused by the supporting rib. It is reliably supported, and it is possible to eliminate problems such as an unstable operation part during tilting operation.

また、上記レジスタにおいて、上記中央軸支部は、硬質合成樹脂により略円筒状に成形され、ボール穴を有する軟質弾性軸受部が該中央軸支部の内側に嵌着され、該中央軸支部の外周部に前記可動フィンの支軸を軸支する軸支部を設けることができる。これによれば、中央軸支部内の軟質弾性軸受部とボールジョイントのボールとの間に適度な摩擦抵抗を生じさせ、適正な操作荷重を操作部に傾動操作時に付与することができ、さらに中央軸支部の各軸支部では可動フィンの支軸を緻密に軸支して、寸法公差などに伴う軸支部のがたつきをなくすことができる。   In the register, the central shaft support portion is formed in a substantially cylindrical shape by a hard synthetic resin, and a soft elastic bearing portion having a ball hole is fitted inside the central shaft support portion, and an outer peripheral portion of the central shaft support portion. A shaft support portion for supporting the support shaft of the movable fin can be provided. According to this, an appropriate frictional resistance can be generated between the soft elastic bearing portion in the central shaft support portion and the ball joint ball, and an appropriate operation load can be applied to the operation portion during the tilting operation. In each shaft support portion of the shaft support portion, the support shafts of the movable fins are supported in a precise manner, and shakiness of the shaft support portion due to dimensional tolerances can be eliminated.

本発明のレジスタによれば、回動ルーバーの可動フィンを回動操作して、流路を可動フィンにより閉鎖したとき、隙間なく流路を閉じて、風漏れをなくすことができる。   According to the register of the present invention, when the movable fin of the rotating louver is rotated and the flow path is closed by the movable fin, the flow path can be closed without a gap, and wind leakage can be eliminated.

The shaft hole 42 of the disposed shaft support portion 4 has a structure that supports the ball 81 of the ball joint 8 and the support shaft 27 inside the five movable fins 23 so as to be able to rotate while giving a good operation load. It has become. 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 the five shaft support portions 4 provided radially on the outer periphery of the central shaft support portion 3 The support shafts 27 inside the five movable fins 23 are pivotally attached to each other.

回動ルーバー２の５枚の可動フィン２３は、図４、５、１０などに示す如く、円筒フレーム２０内に等間隔（約７２°の角度間隔）で配置され、各可動フィン２３の外側の支軸２４は、各々、図４に示すように、円筒フレーム２０の前円筒フレーム２１と後円筒フレーム２２との間に挟むように軸支され、内側の各支軸２７は上記中央軸支部３の外周部に等間隔（約７２°の角度間隔）で配置された各軸支部４の軸穴４２に、嵌入され、各可動フィン２３は、放射状の軸線の回りで回動可能に軸支される。   As shown in FIGS. 4, 5, 10, etc., the five movable fins 23 of the rotating louver 2 are arranged at equal intervals (an angular interval of about 72 °) in the cylindrical frame 20. As shown in FIG. 4, each of the support shafts 24 is supported so as to be sandwiched between the front cylindrical frame 21 and the rear cylindrical frame 22 of the cylindrical frame 20. Are inserted into the shaft holes 42 of the respective shaft support portions 4 arranged at equal intervals (an angular interval of about 72 °) on the outer peripheral portion of each, and the respective movable fins 23 are rotatably supported around the radial axis. The

上記の如く、中央軸支部３は、高分子弾性体により一体成形されるので、ボールジョイント８のボール８１に対し、中央軸支部３のボール穴３２は適度な摩擦抵抗をもって回動可能に保持することができる。さらに、各可動フィン２３の内側の支軸２７は、中央軸支部３の軸支部４の軸穴４２に適度な摩擦抵抗をもって軸支され、中央軸支部３の前部に内側軸部５４を介して支持され操作部６の操作により回動するベベルギヤ部材５１は、中央軸支部３の軸穴３１ａとの間に適度な摩擦抵抗が生じ、これにより、調整可能な適正操作荷重を操作部６に付与することができる。図８、１０、１６に示すように、中央軸支部３の前部の中央軸３１には、軸穴３１ａが設けられ、ベベルギヤ部材５１の内側軸部５４がこの軸穴３１ａに回動可能に嵌入され、ベベルギヤ部材５１の前部の軸部５２には操作部６の軸部６１が嵌入される。   As described above, since the central shaft support portion 3 is integrally formed of a polymer elastic body, the ball hole 32 of the central shaft support portion 3 holds the ball 81 of the ball joint 8 so as to be rotatable with an appropriate frictional resistance. be able to. 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. As shown in FIGS. 8, 10 and 16, the central shaft 31 at the front of the central shaft support portion 3 is provided with a shaft hole 31a, and the inner shaft portion 54 of the bevel gear member 51 is rotatable in the shaft hole 31a. 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.

このため、使用者が操作部６を回して回動ルーバー２を開閉操作したとき、ベベルギヤ部材５１を回動させるとともに、可動フィン２３を支軸２４、２７の回りで回動させながら、適度な操作荷重を生じさせ、可動フィン２３を支軸２４、２７の回りで回動させることができる。さらに、図１８のように、操作部６を持って傾動操作または回動操作して回動ルーバー２の向きを変えるとき、ボール８１と中央軸支部３のボール穴３２間で、適度な操作荷重を生じさせて、回動ルーバー２を左右上下に振ることができるようになっている。   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.

操作部６は、図４、８，１０などに示す如く、ダイヤルノブ状に形成され、回動ルーバー２の円筒フレーム２０の前部の格子部２１ａの中央に、回動操作可能に装着される。図８，１６のように、格子部２１ａの中央には、操作部保持部２１ｂが円形凹部として形成され、その操作部保持部２１ｂの中央に、挿入孔２１ｃが設けられる。その挿入孔２１ｃには前部から操作部６の軸部６１が挿入され、後部からはベベルギヤ部材５１の軸部５２が操作部６の軸部６１内に挿通され、その軸部５２に設けた係止爪５３が軸部６１の係止部６２に係止されて、操作部６とベベルギヤ部材５１が回動操作可能に連結されて、円筒フレーム２０の中央に取り付けられる。   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.

図５，１０、１６に示す如く、操作部６が操作部保持部２１ｂ内に挿入され、且つその軸部６１が挿入孔２１ｃに挿入され、ベベルギヤ部材５１の係止爪５３が操作部６の軸部６１の係止部６２に係止されるので、操作部６をがたつきなく回動可能に取り付けることができ、操作部６の回動操作により、ベベルギヤ機構５のベベルギヤ部材５１が中央軸支部３に対し回動し、中央軸支部３の外周部に放射状に配置された各可動フィン２３を、その支軸２４，２７を軸に回動させる。なお、図３、４に示すように、操作部６はベゼル９の空気吹出口９ｂより少し前方に突出して設けられ、これにより、使用時、使用者は操作部６を容易に持って傾動操作または回動操作することができるようになっている。   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.

ベベルギヤ機構５のベベルギヤ部材５１は、中央軸支部３の中央軸３１を軸にして回動し、図４，５に示すように、中央軸支部３から放射状にのびる各軸支部４に軸支された各可動フィン２３に内側端部に設けたベベルギヤ片２５がベベルギヤ部材５１と噛合する。このため、操作部６を回動操作すると、ベベルギヤ部材５１を介してベベルギヤ片２５が従動して回動し、回動ルーバー２の各可動フィン２３は、その支軸２４、２７を軸に回動する。つまり、ベベルギヤ機構５は、図１０に示すように、駆動側のベベルギヤ部材５１と従動側のベベルギヤ片２５とが噛合して構成され、駆動側のベベルギヤ部材５１はその中央に軸部５２が突設され、軸部５２は操作部６の中央に連結される。軸部５２は、前円筒フレーム２１の格子部２１ａの中央に設けた操作部保持部２１ｂの挿入孔２１ｃに挿通されて、回転可能に支持される。   The bevel gear member 51 of the bevel gear mechanism 5 rotates about the central shaft 31 of the central shaft support portion 3 and is supported by the shaft support portions 4 extending radially from the central shaft support portion 3 as shown in FIGS. Each 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.

また、ベベルギヤ機構５のベベルギヤ部材５１の後部（背面側）には、図１１、１６に示すように、内側軸部５４が内側に突設され、この内側軸部５４は、中央軸支部３の中央軸３１の軸穴３１ａ内に、回動可能に挿通される。さらに、ベベルギヤ部材５１の前部の軸部５２が、操作部６の軸部６１の軸穴内に嵌入され、軸部５２の係止爪５３が軸部６１の係止部６２に係止される。これにより、駆動側のベベルギヤ部材５１は中央軸支部３の中央軸３１に回動可能に支持されるとともに、操作部６の軸部６１と連結される。このように、ベベルギヤ部材５１の係止爪５３が操作部６の軸部６１の係止部６２に係止され、操作部６が操作部保持部２１ｂ内に挿入され、その軸部６１が挿入孔２１ｃに挿入されるので、操作部６は、回動ルーバー２の中央位置に、がたつきなく適度な操作荷重を持って回動可能に取り付けられる。   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.

一方、回動ルーバー２の可動フィン２３は、図１０，１２に示すように、５枚のフィンから構成され、各可動フィン２３の内側部分には、駆動側のベベルギヤ部材５１と噛合する従動側のベベルギヤ片２５が一体成形され、その内側軸中心位置に、支軸２７が突設される。各可動フィン２３は、その内側に設けた内側の支軸２７を、中央軸支部３の軸支部４の軸穴４２に挿入して支持され、ベベルギヤ片２５はその前部に位置するベベルギヤ部材５１と噛合する。各可動フィン２３の回動範囲は約９０°に設定されるため、ベベルギヤ片２５は円環ホイール状に形成する必要はなく、図１２に示すように、約１８０°の角度範囲つまり略半円形の歯部として形成される。上記構成の回動ルーバー２は、その中央の操作部６を持って、回動ルーバー２を上下左右任意の方向に傾動操作すれば、図２２の如く、ボールジョイント８のボール８１を中心に、任意の方向に傾動または回動することができる。   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. When the rotating louver 2 having the above-described configuration has the operation portion 6 at the center and tilts the rotating louver 2 in any direction, up, down, left, and right, as shown in FIG. 22, the ball 81 of the ball joint 8 is centered. It can be tilted or rotated in any direction.

上記の如く、回動ルーバー２は、５枚の可動フィン２３を有して構成され、中央軸支部３の外周部に軸支部４を放射状に設け、各軸支部４の軸穴４２に、各可動フィン２３の内側の支軸２７を嵌入支持させて、円筒フレーム２０の内側に５枚の可動フィン２３が、略等間隔（約７２度の角度間隔）で放射状に、回動可能に配置される。そして、各可動フィン２３は、そのラジアル方向外側に突設された支軸２４を円筒フレーム２０の前円筒フレーム２１と後円筒フレーム２２間に挟持させる。これにより、各可動フィン２３は中央軸支部３の外周方向に放射状にのびる内側と外側の支軸２４、２７を軸に回動可能に軸支される。   As described above, the rotating louver 2 is configured to include 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 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.

このような回動ルーバー２は、各可動フィン２３をその支軸２４、２７の回りで所定角度まで回動させたとき、その回動端で可動フィン２３のフィン本体２６が円筒フレーム２０の横断面と略平行状態となって、流路１５を閉鎖する。そのために、５枚の可動フィン２３のフィン本体２６は、流路１５の通風方向と直角な横断面に並置状態となってとき、全閉可能な形状及び大きさに形成される。   In such a rotating louver 2, when each movable fin 23 is rotated to a predetermined angle around its support shafts 24, 27, the fin body 26 of the movable fin 23 crosses the cylindrical frame 20 at the rotation end. The flow path 15 is closed in a state substantially parallel to the surface. 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.

つまり、回動ルーバー２が、５枚の可動フィン２３を通風方向と直角な横断面と平行な状態まで回動させたとき、流路１５を全閉状態とする形状及び大きさに可動フィン２３は形成される。回動ルーバー２は、５枚の可動フィン２３を並置するため、４枚の可動フィンの場合より、可動フィン２３のフィン本体２６の大きさを小形化することができる。これにより、回動ルーバー２は、上下左右等への傾動時、可動フィン２３をボールジョイント８に干渉させずに、所定の最大角度まで傾動することができる。   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.

しかも、回動ルーバー２の可動フィン２３を５枚とした場合、各可動フィン２３をその支軸２４、２７を軸に回動させて送風を拡散させたとき、従来のように４枚の可動フィンを配設した回動ルーバーの場合より、送風時の風の拡散は、より高い効率で行なわれ、空気吹出口の周囲に、効率良く拡散されたマイルドな風を送風できるようになっている。   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. .

さらに、上記のように、可動フィン２３の小形化に伴い、可動フィン２３が流路１５の軸方向（送風方向）と平行になった状態の軸方向の長さを短くすることができる。このため、リテーナ１の長さを、従来の４枚の可動フィンのレジスタより、短くすることができ、これにより、レジスタの設置スペースを省スペース化することができるようになっている。   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.

ところで、回動ルーバー２の５枚の可動フィン２３は、操作部６を回動操作して流路１５を閉じる操作をしたとき、図１２，１７、１９〜２１に示す如く、中心線Ｓ２と垂直な状態、つまり通風方向と直角な横断面と平行な状態まで回動させたとき、流路１５を閉鎖する。そのために、各可動フィン２３は、円形の流路１５を５枚の可動フィン２３で覆い得る形状に形成されるが、可動フィンの縁部近傍などで微妙な隙間が生じやすく、風漏れが発生しやすい。このため、後円筒フレーム２２の内側前部には、フィン当て縁部２２ｃが５枚の可動フィン２３の外側縁部が当接可能な位置の外周に沿って設けられる。操作部６を回動操作して、可動フィン２３が回動し流路１５を閉鎖したとき、可動フィン２３の外周縁部がフィン当て縁部２２ｃに当接し、可動フィン２３の外周部と円筒フレーム２０の内側面との隙間を埋めるようになっている。   By the way, the five movable fins 23 of the rotation louver 2 are arranged so that when the operation unit 6 is rotated and the flow path 15 is closed, as shown in FIGS. When turned to a vertical state, that is, a state parallel to a cross section perpendicular to the ventilation direction, the flow path 15 is closed. Therefore, each movable fin 23 is formed in a shape that can cover the circular flow path 15 with five movable fins 23, but a delicate gap is likely to occur near the edge of the movable fin and wind leakage occurs. It's easy to do. For this reason, at the inner front part of the rear cylindrical frame 22, the fin contact edge part 22c is provided along the outer periphery of the position where the outer edge part of the five movable fins 23 can come into contact. When the operation unit 6 is rotated to move the movable fin 23 to close the flow path 15, the outer peripheral edge of the movable fin 23 abuts the fin contact edge 22 c, and the outer peripheral part of the movable fin 23 and the cylinder A gap with the inner surface of the frame 20 is filled.

さらに、可動フィン２３のフィン本体２６の元部には、図１２、１７に示す如く、隙間閉鎖用凸部２８が突設され、可動フィン２３を閉鎖位置まで回動させて、流路１５を閉鎖したときのフィン元部近傍に発生しやすい隙間を閉鎖するようにしている。つまり、図１９に示す如く、操作部６の回動操作により可動フィン２３を閉鎖位置まで回動させたとき、可動フィン２３のフィン本体２６の元部近傍とそれに隣接する可動フィン２３のフィン本体２６の元部近傍との間の隙間を閉じるように、各可動フィン２３のフィン本体２６の元部に、隙間閉鎖用凸部２８が設けられている。   Further, as shown in FIGS. 12 and 17, a gap closing convex portion 28 protrudes from the base portion of the fin body 26 of the movable fin 23, and the movable fin 23 is rotated to the closed position so that the flow path 15 is formed. A gap that is likely to occur in the vicinity of the fin base when closed is closed. That is, as shown in FIG. 19, when the movable fin 23 is rotated to the closed position by the rotation operation of the operation unit 6, the vicinity of the base portion of the fin body 26 of the movable fin 23 and the fin body of the movable fin 23 adjacent thereto. A gap closing convex part 28 is provided at the base part of the fin body 26 of each movable fin 23 so as to close the gap between the base part 26 and the vicinity of the base part 26.

加えて、回動ルーバー２の中央に位置する中央軸支部３の外周部には、５個の軸支部４が放射状に突設されるが、図１３に示す如く、それらの軸支部４と軸支部４の間の空間つまり隙間を埋めるように、隙間閉鎖用リブ４１が中央軸支部３の外周部に設けられる。これらの隙間閉鎖用リブ４１は、軸支部４と軸支部４の間の隙間を埋めるために略三角形状に形成され、図１９に示すように、可動フィン２３を閉鎖位置まで回動させたとき、中央軸支部３の各軸支部４と各可動フィン２３の隙間を閉じる形状となっている。   In addition, five shaft support portions 4 project radially from the outer peripheral portion of the central shaft support portion 3 located at the center of the rotating louver 2, but as shown in FIG. A gap closing rib 41 is provided on the outer peripheral portion of the central shaft support 3 so as to fill the space between the supports 4, that is, the gap. These gap closing ribs 41 are formed in a substantially triangular shape so as to fill the gap between the shaft support portion 4 and the shaft support portion 4, and when the movable fin 23 is rotated to the closed position as shown in FIG. The gap between each shaft support 4 and each movable fin 23 of the central shaft support 3 is closed.

上記構成により、駆動側のベベルギヤ部材５１が操作部６により回動したとき、従動側の各ベベルギヤ片２５が軸支部４を中心に約９０°の範囲で回転し、これにより可動フィン２３が、軸支部４の回りで、回動ルーバー２の中心線Ｓ２と平行な状態から中心線Ｓ２と垂直な垂直面と平行な状態まで回動し、図１９〜２１に示すように、流路１５が閉鎖される。このとき、回動ルーバー２の可動フィン２３の外周部の隙間は、フィン当て縁部２２ｃにより閉鎖され、可動フィン２３の元部近傍の隙間は、フィン本体２６に設けた隙間閉鎖用凸部２８と軸支部４と軸支部４との間に設けた隙間閉鎖用リブ４１により良好に閉じられる構造となっている。   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 as shown in FIGS. Closed. At this time, the gap in the outer peripheral portion of the movable fin 23 of the rotating louver 2 is closed by the fin abutting edge portion 22 c, and the gap in the vicinity of the base portion of the movable fin 23 is a gap closing convex portion 28 provided in the fin body 26. In addition, the structure is satisfactorily closed by a gap closing rib 41 provided between the shaft support 4 and the shaft support 4.

上記構成の回動ルーバー２を組み立てる場合、図１０，１６に示す如く、操作部６を前円筒フレーム２１の前部の操作部保持部２１ｂ内に挿入しながら、その軸部６１を挿入孔２１ｃに挿入し、前円筒フレーム２１の後部側からベベルギヤ部材５１の軸部５２を、操作部６の軸部６１内に差し込み、その係止爪５３を係止部６２に係止させる。これにより、操作部６及びベベルギヤ部材５１は前円筒フレーム２１の中央軸線位置に、確実に回動可能に組み付けられ、操作部６にがたつきが生じたりベベルギヤ部材５１が外れる不具合は防止される。   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. .

次に、中央軸支部３の外周部の軸支部４に、５枚の可動フィン２３を放射状に保持させるように、内側の支軸２７を軸穴４２に挿入し、中央軸支部３の中央軸３１の軸穴３１ａをベベルギヤ部材５１の内側軸部５４に嵌入する。その状態で、５枚の可動フィン２３の外側の支軸２４を、前円筒フレーム２１と後円筒フレーム２２間の軸受部で挟み込み軸支するようにして、前円筒フレーム２１と後円筒フレーム２２を嵌合させ、その係止爪２２ａと係止部２１ｄを係止させる。   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.

この状態で、５枚の可動フィン２３の元部に設けたベベルギヤ片２５は中央のベベルギヤ部材５１と噛合した状態となり、操作部６を回動操作すると、ベベルギヤ部材５１が中央軸支部３に対し回動し、その回動力がベベルギヤ片２５を介して５枚の可動フィン２３に伝達されて可動フィン２３が支軸２４，２７を軸に回動し、円筒フレーム２０内の流路が開閉される。   In this state, the bevel gear piece 25 provided at the base portion of the five movable fins 23 is engaged with the central bevel gear member 51, and when the operation unit 6 is rotated, the bevel gear member 51 is moved with respect to the central shaft support unit 3. 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

このように組み立てられた回動ルーバー２に対し、ボールジョイント８のボール８１を中央軸支部３の後部のボール穴３２に嵌入し、その状態で、図８、９，１６に示す如く、ボールジョイント８の軸部８２を、リテーナ１内のボールジョイント支持部１１内に差し込み、ベゼル９を回動ルーバー２の前部を覆うように、リテーナ１の前部に嵌め込む。このとき、円筒フレーム２０の後円筒フレーム２２の外周部に突設されたガイド凸部２２ｂは、リテーナ１の前部内周部に設けたガイド溝１ａ（図９）に進入し、さらにガイド凸部２２ｂはベゼル９のガイド溝９ｄ（図４）にも進入可能となる。リテーナ１の係止部１３にベゼル９の係止爪９ａが係止され、レジスタの組立てが完了する。   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. 22 b can enter the guide groove 9 d (FIG. 4) of the bezel 9. 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.

なお、このレジスタは、円筒フレーム２０と可動フィン２３を設けた回動ルーバー２が、リテーナ１内に、ボールジョイント８によって回動可能に収納支持され、その前部にベゼル９が嵌着され、回動ルーバー２の円筒フレーム２０は、リテーナ１内で、その外周面とリテーナ１の内周面との間に僅かな隙間をもって、非接触で回動可能に支持される。このため、回動ルーバー２を傾動操作する際、スムーズに傾動させることができるが、送風時、円筒フレーム２０の外周面とリテーナ１の内周面との間に生じる僅かな隙間に、漏れ空気流が流れる場合がある。このような場合には、図５，７に示す如く、必要に応じて、後円筒フレーム２２の外周面とリテーナ１の内周面との隙間に、不織布シート２９を介装すれば、漏れ空気流を一層低減することができる。   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 necessary, a non-woven 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, thereby leaking air. The flow can be further reduced.

上記構成のレジスタは、例えば自動車のインストルメントパネルに設けられた空調装置の空気吹出口等に装着して使用される。レジスタの送風方向を変える場合、操作部６を持って回動ルーバー２を傾動操作或いは回動操作して行なう。操作部６はダイヤル状に形成され且つベゼル９の空気吹出口９ｂより少し前方に突出して配設されるため、使用者は容易に操作部６を持って傾動操作或いは回動操作が可能である。   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. .

図２，４に示すように、回動ルーバー２がレジスタの正面前方に真直ぐな状態にあるとき、つまり、回動ルーバー２の可動フィン２３が流路１５の軸方向に沿った中心線Ｓ２と平行な状態にあるとき、空気流は回動ルーバー２の可動フィン２３にガイドされて前方に真直ぐ送風され、このとき、前方の比較的狭い範囲に集中して送風が行なわれる。   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.

一方、空気吹出口９ｂの前方の周囲における比較的広い範囲に、拡散して送風する場合、操作部６を持って中心線Ｓ２を軸に捻るように右または左に回す。   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.

このとき、操作部６の回動力はベベルギヤ機構５の軸部５２を介してベベルギヤ部材５１に伝達され、ベベルギヤ部材５１が回転し、その回転がベベルギヤ部材５１と噛合する５枚の可動フィン２３のベベルギヤ片２５に伝達され、５枚の可動フィン２３はその支軸２４、２７を軸に回動し、各可動フィン２３のフィン本体２６が流路１５の横断面に沿ったラジアル方向の軸の回りで、前後に傾くように回動する。   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.

これにより、空気流は、回動ルーバー２を通過する際、回動ルーバー２の中心線Ｓ２の回りで旋回するように周囲に広って送風され、空気吹出口９ｂの周囲に拡散するように送風される。またこのとき、送風は空気吹出口の内側に配置された５枚の可動フィン２３により、周囲にガイドされて拡散されるので、従来の４枚の可動フィンの場合に比べ、よりマイルドな風を送風することができる。   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.

一方、送風を遮断する場合には、操作部６をさらに右または左に回動端まで回す。これにより、回動ルーバー２の各可動フィン２３は、図１９に示すように、支軸２４、２７を軸に、中心線Ｓ１，Ｓ２と垂直な垂直面と平行な状態（流路の遮断状態）まで回動し、これによって流路１５は全閉状態となり、送風は遮断される。   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. Thereby, as shown in FIG. 19, each movable fin 23 of the rotating louver 2 is in a state parallel to the vertical plane perpendicular to the center lines S1 and S2 (the flow path blocking state) with the support shafts 24 and 27 as axes. ), The flow path 15 is fully closed, and the air flow is blocked.

このとき、回動ルーバー２の可動フィン２３の外周部の隙間は、可動フィン２３の外周縁部がフィン当て縁部２２ｃに当たることより閉鎖され、可動フィン２３の元部近傍の隙間は、図１９，２０に示す如く、フィン本体２６に設けた隙間閉鎖用凸部２８と軸支部４と軸支部４との間に設けた隙間閉鎖用リブ４１により良好に閉じられることとなる。したがって、流路１５の閉鎖時の風漏れを最小にすることができる。   At this time, the clearance between the outer peripheral portions of the movable fins 23 of the rotating louver 2 is closed by the outer peripheral edge of the movable fins 23 coming into contact with the fin abutting edge 22c. , 20, the gap closing convex portion 28 provided on the fin body 26 and the gap closing rib 41 provided between the shaft supporting portion 4 and the shaft supporting portion 4 are satisfactorily closed. Therefore, it is possible to minimize wind leakage when the flow path 15 is closed.

一方、風向を斜め上方に向ける場合、操作部６を持って持ち上げるように操作すると、図２２（ａ）のように、操作部６を含む回動ルーバー２がボールジョイント８のボール８１を中心に上側に回動（傾動）し、リテーナ１の中心線Ｓ１に対し回動ルーバー２の中心線Ｓ２が図２２（ａ）のように上側に傾斜し、これにより、送風方向は斜め上方に向けられる。同様に、風向を斜め下上方に向ける場合、操作部６を持って下げるように操作すると、図２２（ｂ）のように、操作部６を含む回動ルーバー２がボールジョイント８のボール８１を中心に下側に回動（傾動）し、リテーナ１の中心線Ｓ１に対し回動ルーバー２の中心線Ｓ２が図２２（ｂ）のように下側に傾斜し、送風方向は斜め下方に向けられる。このように、操作部６を上下或いは左右等と任意の方向に傾動操作することにより、風向を任意の方向に向けることができる。   On the other hand, when the wind direction is directed obliquely upward, when the operation unit 6 is operated to lift it, 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. 22 (a) with respect to the center line S1 of the retainer 1, and thereby the blowing direction is directed obliquely upward. . 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 with respect to the center line S1 of the retainer 1 as shown in FIG. 22B, and the blowing direction is directed obliquely downward. It is done. Thus, the wind direction can be directed to an arbitrary direction by tilting the operation unit 6 in an arbitrary direction such as up and down or left and right.

このとき、回動ルーバー２の操作部６による傾動操作及び回動操作は、高分子弾性体製の中央軸支部３を介して行なわれ、傾動操作時、回動ルーバー２はボールジョイント８のボール８１の周面を中央軸支部３のボール穴３２が摺動して傾動するので、がたつきなく適度な操作荷重（摩擦抵抗）を生じさせ、滑らかな操作フィーリングをもって、傾動操作することができる。   At this time, the tilting operation and the rotating operation by the operating portion 6 of the rotating louver 2 are performed through the central shaft support portion 3 made of a polymer elastic body. During the tilting operation, the rotating louver 2 moves the ball of the ball joint 8. Since the ball hole 32 of the central shaft support portion 3 slides and tilts on the peripheral surface of 81, an appropriate operation load (friction resistance) is generated without rattling, and the tilt operation can be performed with a smooth operation feeling. it can.

また、操作部６を回動操作した際、ベベルギヤ部材５１が回動し、その回動力がベベルギヤ片２５を介して５枚の可動フィン２３に伝達され、各可動フィン２３はその支軸２４，２７を軸に回動するが、ベベルギヤ部材５１はその内側軸部５４を中央軸支部３の中央軸３１の軸穴３１ａに摺接させて回動し、可動フィン２３の支軸２７は中央軸支部３の軸支部４の軸穴４２内を摺接して回動するので、この場合も、がたつきなく適度な操作荷重（摩擦抵抗）を生じさせ、滑らかな操作フィーリングをもって、回動操作することができる。   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 through 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.

一方、上記のように回動ルーバー２を傾動させた状態で、さらに操作部６を中心線Ｓ２の回りで回動操作すると、上記と同様、操作部６の回動力がベベルギヤ機構５の軸部５２を介してベベルギヤ部材５１に伝達され、ベベルギヤ部材５１が回転し、その回転がベベルギヤ部材５１と噛合する５枚の可動フィン２３のベベルギヤ片２５に伝達され、５枚の可動フィン２３はその支軸２４、２７を軸に回動する。これにより、回動ルーバー２を通過する空気流は、中心線Ｓ２に沿って集中して送風される状態から、回動ルーバー２の中心線Ｓ２の回りで旋回するように周囲に拡散する状態まで変化し、上記と同様に、送風状態を集中状態から拡散状態まで変えるように調整することができる。そして、操作部６を閉鎖方向に限界まで回動操作すると、図１９，２０に示すように、５枚の可動フィン２３が流路１５を完全に閉鎖する状態まで回動して、流路１５は閉鎖される。   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. When the operation unit 6 is turned to the limit in the closing direction, as shown in FIGS. 19 and 20, the five movable fins 23 are turned until the flow path 15 is completely closed, and the flow path 15 Is closed.

このように、回動ルーバー２の中央の操作部６を持って回動ルーバー２を任意の方向に傾動操作したとき、回動ルーバー２は、中央に支持されたボールジョイント８のボール８１を中心に中央軸支部３を介して傾動するので、安定した滑らかな操作フィーリングで、回動ルーバーを傾動させて風向を変えることができ、操作部６を回動端まで回動操作した場合、後円筒フレーム２２の内側に設けたフィン当て縁部２２ｃ、フィン本体２６に設けた隙間閉鎖用凸部２８、及び中央軸支部３の軸支部４間の隙間閉鎖用リブ４１により良好に閉じられ、流路１５の閉鎖時の風漏れを最小にすることができる。
る。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. Tilting through the central shaft support portion 3, the direction of the wind can be changed by tilting the rotating louver with a stable and smooth operation feeling, and when the operating portion 6 is rotated to the rotating end, The fin closing edge 22c provided on the inner side of the cylindrical frame 22, the gap closing convex portion 28 provided on the fin body 26, and the gap closing rib 41 between the shaft supporting portions 4 of the central shaft supporting portion 3 are satisfactorily closed. Wind leakage when the path 15 is closed can be minimized.
The

図２３〜図２６は、他の実施形態のレジスタを示している。この実施形態のレジスタでは、中央軸支部１０３が、硬質合成樹脂により成形された軸支部１０４と、軸支部１０４の内側に嵌入されるシリコーンゴム等の高分子弾性体製の軟質弾性軸受部１３０とから、分割形成される。また、ベベルギヤ部材１５１の歯部側の中央嵌合穴１５６の周囲に、支持用リブ１５５が設けられ、中央軸支部１０３とベベルギヤ部材１５１を結合したとき、支持用リブ１５５が中央軸支部１０３の隙間閉鎖用リブ１４１に当接して嵌合部１３４を確実に支持する構造である。なお、上記実施形態と同様の部分については、図に上記と同じ符号を付してその説明を省略する。   23 to 26 show a register according to another embodiment. In the register of this embodiment, the central shaft support portion 103 includes a shaft support portion 104 formed of a hard synthetic resin, and a soft elastic bearing portion 130 made of a polymer elastic body such as silicone rubber fitted inside the shaft support portion 104. Are divided and formed. Further, a support rib 155 is provided around the central fitting hole 156 on the tooth portion side of the bevel gear member 151, and when the central shaft support portion 103 and the bevel gear member 151 are coupled, the support rib 155 is provided on the central shaft support portion 103. In this structure, the fitting portion 134 is reliably supported by contacting the gap closing rib 141. In addition, about the part similar to the said embodiment, the same code | symbol as the above is attached | subjected to a figure, and the description is abbreviate | omitted.

回動ルーバー２は、上記と同様、リテーナ１及びベゼル９内に円筒フレーム１２０を配設し、円筒フレーム１２０内に５枚の可動フィン２３を放射状に配設し、それらの可動フィン２３の内側の支軸２７を中央軸支部１０３の軸支部１０４で回動可能に軸支して構成される。図２３に示すように、円筒フレーム１２０の前円筒フレーム１２１の中央に操作部（ダイヤルノブ）１０６が回動可能に軸支され、操作部１０６の回動操作に応じて、ベベルギヤ機構のベベルギヤ部材１５１とベベルギヤ片２５を介して、放射状の軸支部１０４で軸支される５枚の可動フィン２３を、各々の支軸２４、２７を中心に回動させ、流路１５を開閉する。   As described above, the rotating louver 2 includes a cylindrical frame 120 disposed in the retainer 1 and the bezel 9, and five movable fins 23 are disposed radially in the cylindrical frame 120. The support shaft 27 is rotatably supported by the shaft support portion 104 of the central shaft support portion 103. As shown in FIG. 23, an operation portion (dial knob) 106 is pivotally supported at the center of the front cylindrical frame 121 of the cylindrical frame 120, and the bevel gear member of the bevel gear mechanism according to the rotation operation of the operation portion 106. The movable fins 23 supported by the radial shaft support 104 are rotated about the support shafts 24 and 27 through the shafts 151 and the bevel gear pieces 25 to open and close the flow path 15.

円筒フレーム１２０は、回動ルーバー２を内部に組み付けた状態で、前円筒フレーム１２１の後部に後円筒フレーム１２２を嵌め込み、係止爪を係止部に係止させ、前円筒フレーム１２１と後円筒フレーム１２２を嵌合させて構成される。図２３に示すように、前円筒フレーム１２１の前部内周部には、絞り湾曲面１２１ａが形成され、この絞り湾曲面１２１ａにより、円筒フレーム１２０内の流路を通過する風が適度に絞られ、送風時の風の指向性を向上させるようになっている。   In the state in which the rotating louver 2 is assembled inside the cylindrical frame 120, the rear cylindrical frame 122 is fitted into the rear portion of the front cylindrical frame 121, and the locking claws are locked to the locking portion. The frame 122 is configured to be fitted. As shown in FIG. 23, a diaphragm curved surface 121a is formed in the front inner peripheral portion of the front cylindrical frame 121, and the wind passing through the flow path in the cylindrical frame 120 is appropriately throttled by the diaphragm curved surface 121a. The directivity of the wind at the time of ventilation is improved.

さらに、後円筒フレーム１２２の外周前部に、フィン当て縁部が５枚の可動フィン２３の外側縁部が当接する位置に設けられ、可動フィン２３が流路１５を閉鎖したとき、可動フィン２３の外周縁部がフィン当て縁部に当接し、隙間を埋める構造である。   Further, the fin abutting edge portion is provided at a position where the outer edge portion of the five movable fins 23 abuts on the outer peripheral front portion of the rear cylindrical frame 122, and when the movable fin 23 closes the flow path 15, the movable fin 23 The outer peripheral edge part of this is in contact with the fin abutting edge part to fill the gap.

また、後円筒フレーム２２の外周後部には、ガイド凸部１２２ｂが突設される。ガイド凸部１２２ｂは、リテーナ１及びベゼル９の内周部軸方向に設けたガイド溝１ａ、９ｄ内に移動可能に進入し、円筒フレーム１２０が傾動操作されたとき、ガイド凸部１２２ｂがガイド溝１ａ、９ｄ内を移動し、回動ルーバー２の傾動をガイドする。ガイド凸部１２２ｂには、高分子弾性体などからなるゴム状弾性を有する弾性リング１２２ｄが外嵌され、傾動操作時に、ガイド凸部１２２ｂがガイド溝１ａ，９ｄ内の縁部に当接したときの衝撃を緩衝するようになっている。また、ガイド溝１ａ，９ｄ内のガイド凸部１２２ｂは、回動ルーバー２の中央の操作部１０６を回して可動フィン２３を開閉操作したとき、ガイド溝１ａ，９ｄ内に保持されて、円筒フレーム１２０の回転を止めるようにも作用する。   In addition, a guide convex portion 122 b is projected from the outer peripheral rear portion of the rear cylindrical frame 22. The guide protrusion 122b movably enters guide grooves 1a and 9d provided in the axial direction of the inner periphery of the retainer 1 and the bezel 9, and when the cylindrical frame 120 is tilted, the guide protrusion 122b It moves in 1a and 9d and guides the tilting of the rotating louver 2. An elastic ring 122d having a rubber-like elasticity made of a polymer elastic body or the like is externally fitted to the guide convex portion 122b, and when the guide convex portion 122b comes into contact with the edge in the guide grooves 1a and 9d during the tilting operation. It is designed to buffer the impact of The guide protrusions 122b in the guide grooves 1a and 9d are held in the guide grooves 1a and 9d when the movable fin 23 is opened / closed by turning the operation portion 106 at the center of the rotating louver 2, and the cylindrical frame It also acts to stop 120 rotation.

さらに、円筒フレーム１２０は、それを上下に傾動操作したとき、最大傾動角度で、図２３のように、先ず、中央軸支部１０３の後部の開口縁部が、ボールジョイント１０８の軸部１８２に当接し、次に、前円筒フレーム１２１または後円筒フレーム１２２の縁部が、リテーナ１またはベゼル９内の当接部９ｃに当たり、回動（傾動）を停止する構造となっている。   Further, when the cylindrical frame 120 is tilted up and down, as shown in FIG. 23, the opening edge portion of the rear portion of the central shaft support portion 103 first contacts the shaft portion 182 of the ball joint 108 at the maximum tilt angle. Next, the edge part of the front cylindrical frame 121 or the rear cylindrical frame 122 hits the contact part 9c in the retainer 1 or the bezel 9 to stop the rotation (tilt).

さらに、図２３に示すように、リテーナ１内の支持枠１２の中央にボールジョイント支持部１１が設けられ、ボールジョイント支持部１１にボールジョイント１０８が下流側を向けて取り付けられる。ボールジョイント１０８の下流側の先端に位置するボール１８１に、回動ルーバー２の中央軸支部１０３が自在回動可能に外嵌される。図２３に示すように、ボールジョイント１０８は、軸部１８２の先端にボール１８１を設けて、合成樹脂により成形される。   Further, as shown in FIG. 23, a ball joint support portion 11 is provided at the center of the support frame 12 in the retainer 1, and the ball joint 108 is attached to the ball joint support portion 11 with the downstream side facing.
