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、外枠と回動ルーバーの内枠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問題となる。 However, in this conventional register, when the movable blade is rotated to a state parallel to the cross section of the flow path and the flow path is closed, a gap is easily generated between the outer frame and the inner frame of the rotation louver. When the gap is large due to an error within the tolerances of the respective component dimensions, airflow leaks from the gap when the air is closed, and air leakage occurs when the flow path is closed.

さらに、外枠と内枠間の隙間がゼロで、その外周面と内周面が強く接触した状態で組み付けられた場合、回動ルーバーの方向調整操作時、がたつき、過大な操作荷重、或いはゴリゴリ感などが発生しやすい。 Furthermore, when assembled with the gap between the outer frame and the inner frame being zero and the outer peripheral surface and the inner peripheral surface being in strong contact with each other, rattling, excessive operation load, Or, a crisp feeling is likely to occur.

このため、外枠と内枠間に、フェルトなどの不織布を介装することが考えられたが、フェルトなどの不織布はその厚さが製品ごとにばらつきやすく、介装された不織布の厚さが薄い場合、がたつきが生じやすく、外枠と内枠間に隙間が生じて風漏れが発生し、不織布の厚さが厚い場合には、過大な操作荷重やゴリゴリ感が発生する課題があった。 For this reason, it was considered that a nonwoven fabric such as felt was interposed between the outer frame and the inner frame, but the thickness of the nonwoven fabric such as felt was likely to vary from product to product. If it is thin, rattling is likely to occur, a gap is generated between the outer frame and the inner frame, causing wind leakage, and if the nonwoven fabric is thick, there is a problem that an excessive operating load or a harsh feeling is generated. It was.

本発明は、上述の課題を解決するものであり、流路を閉鎖したときの風漏れをなくすとともに、円滑に風向調整操作を行う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 thereof is to provide a round register capable of eliminating wind leakage when a flow path is closed and performing a wind direction adjusting operation smoothly.

該円筒フレームの内側に複数の可動フィンが、略等間隔をおいてラジアル方向の支軸により回動可能に軸支されるとともに、該各可動フィンの内側部分が該中央軸支部の各軸支部に軸支され、
該中央軸支部の前面側中央には操作部が該回動ルーバーの中心線の回りで回動可能に装着され、該操作部はベベルギヤ機構を介して該各可動フィンの内側部分と連係され、
該リテーナの内面と該円筒フレームの外周面間の隙間を塞ぐように、ブラシ状の植毛シート部材が介装され、
該操作部を前記中心線の回りで回動操作したとき、該可動フィンが該ベベルギヤ機構を介して、該中央軸支部の外周部の該軸支部を中心に回動し、該操作部を該円筒フレームのラジアル方向に動かしたとき、該回動ルーバーは前記ボールジョイントの該ボールを中心に傾動し、該植毛シート部材のブラシ毛の先端は、円筒フレームの外周面またはリテーナの内面と摺接すること特徴とする。 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 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 brush-like flocked sheet member is interposed so as to close a gap between the inner surface of the retainer and the outer peripheral surface of the cylindrical frame,
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 moved in the radial direction of the cylindrical frame, the rotating louver tilts about the ball of the ball joint, and the tip of the bristle of the flocking sheet member is in sliding contact with the outer peripheral surface of the cylindrical frame or the inner surface of the retainer. It is a feature.

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し、このとき、リテーナと円筒フレーム間の隙間を塞ぐように介装された植毛シート部材は、そのブラシ毛の先端を、円筒フレームの外周面またはリテーナの内周面に摺接して傾動するので、リテーナと円筒フレーム間に生じやすい隙間を塞ぎつつ、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。また、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。 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. At this time, the flocked sheet member interposed so as to close the gap between the retainer and the cylindrical frame is tilted by sliding the tip of the bristle against the outer peripheral surface of the cylindrical frame or the inner peripheral surface of the retainer. The wind direction can be changed by tilting the rotating louver with a stable and smooth operation feeling while closing a gap that is likely to occur between the retainer and the cylindrical frame. Further, it is possible to minimize wind leakage when the rotating louver is closed.

ここで、上記レジスタにおいて、上記植毛シート部材は、ベースシート上にブラシ毛素材が密集して植込まれ、該ベースシートの底面に接着材層が取着されて構成され、該ベースシートを該接着材層により上記リテーナの内面に、或いは上記円筒フレームの外周面に接着することができる。 Here, in the register, the flocking sheet member is configured such that a bristle material is densely implanted on a base sheet, and an adhesive layer is attached to a bottom surface of the base sheet.

The movable fins 23 are pivotally supported so as to be rotatable about radial axes, and are fitted into the shaft holes 42 of the respective shaft support portions 4 arranged at equal intervals (an angular interval of about 72 °).

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５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 FIG. 5, a shaft hole 31a is provided in the central shaft 31 at the front portion of the central shaft support portion 3, and the inner shaft portion 54 of the bevel gear member 51 is rotatably fitted in the shaft hole 31a. The shaft portion 61 of the operation portion 6 is fitted into the shaft portion 52 at the front portion of the 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、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, when changing the direction of the rotating louver 2 by holding the operating portion 6 to change the direction of the rotating louver 2, an appropriate operating load is generated between the ball 81 and the ball hole 32 of the central shaft support portion 3 to rotate the rotating louver 2. The moving louver 2 can be swung left and right and up and down.

操作部６は、図４、５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。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 and 5, 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 capable of rotating operation. 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。 As shown in FIG. 5, 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 connected to the shaft portion 61 of the operation portion 6. Since it is locked by the locking portion 62, the operation portion 6 can be pivotably attached without rattling, and the bevel gear member 51 of the bevel gear mechanism 5 is attached to the central shaft support portion 3 by the rotation operation of the operation portion 6. The movable fins 23 that rotate relative to each other and are radially arranged on the outer periphery of the central shaft support 3 are rotated about the support shafts 24 and 27.

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２、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。 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 as shown in FIGS. 2, 4, and 5, the bevel gear member 51 is pivoted to 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 supported 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.

つまり、ベベルギヤ機構５は、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。 That is, the bevel gear mechanism 5 is configured such that the drive-side bevel gear member 51 and the driven-side bevel gear piece 25 are engaged with each other, and the drive-side bevel gear member 51 has a shaft portion 52 projecting from the center thereof. It is connected to the center of the operation unit 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５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。 Further, as shown in FIG. 5, an inner shaft portion 54 projects inwardly from the rear portion (back side) of the bevel gear member 51 of the bevel gear mechanism 5, and the inner shaft portion 54 is a central shaft of the central shaft support portion 3. The shaft hole 31a of the 31 is rotatably inserted. 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.

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。 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４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。 On the other hand, the movable fin 23 of the rotating louver 2 is composed of five fins as shown in FIG. 4, and a bevel gear on the driven side that meshes with the bevel gear member 51 on the driving side is formed inside each movable fin 23. The piece 25 is integrally formed, and a support shaft 27 protrudes 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.

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４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７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。 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 a ring wheel, and as shown in FIG. It is formed as a tooth part. The rotating louver 2 having the above-described configuration has the operation portion 6 at its center, and if the rotating louver 2 is tilted up and down, left and right, as shown in FIG. 7, the ball 81 of the ball joint 8 is centered as shown in FIG. It can be tilted or rotated in any direction.

このように、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 have 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.

図２，４，５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の外周部は、略球面の一部から形成され、同様にリテーナ１内の前部の内周面は、略球面の一部から形成される。これにより、円筒フレーム２０は、リテーナ１内でボールジョイント８のボール８１の中心点を中心に、上下左右任意の方向に、傾動・回動可能にリテーナ１内に装着される。 As shown in FIGS. 2, 4, and 5, the outer peripheral portions of the front cylindrical frame 21 and the rear cylindrical frame 22 of the cylindrical frame 20 are formed from a part of a substantially spherical surface, and similarly, the inner peripheral surface of the front portion in the retainer 1. Is formed from a part of a substantially spherical surface. Thereby, the cylindrical frame 20 is mounted in the retainer 1 so as to be tiltable and rotatable in any direction up, down, left and right around the center point of the ball 81 of the ball joint 8 in the retainer 1.

回動ルーバー２の円筒フレーム２０は、図２，３に示すように、リテーナ１内で円滑に傾動・回動可能なように、円筒フレーム２０の外周面とリテーナ１の内周面との間が非接触とされ、その間に僅かな隙間が形成され、この間の隙間を効果的に閉じるために、植毛シート部材２９が当該隙間に介挿される。 As shown in FIGS. 2 and 3, the cylindrical frame 20 of the rotating louver 2 is provided between the outer peripheral surface of the cylindrical frame 20 and the inner peripheral surface of the retainer 1 so that it can be smoothly tilted and rotated in the retainer 1. Is not contacted, and a slight gap is formed therebetween, and the flocked sheet member 29 is inserted into the gap to effectively close the gap therebetween.

植毛シート部材２９は、図６に示すように、ベースシート２９ａ上に多数のブラシ毛素材２９ｂが密集して植え込まれており、ベースシート２９ａの底面には接着材層２９ｃが取着される。このような植毛シート部材２９は、帯状に裁断され、図２，３のように、その底面の接着材層２９ｃをリテーナ１内の前部内周面の全周に沿って配設し、そのブラシ毛素材２９ｂを円筒フレーム２０側に向けて植毛シート部材２９は接着材層２９ｃによりリテーナ１内に接着される。 As shown in FIG. 6, the flocking sheet member 29 has a large number of brush bristle materials 29b planted densely on the base sheet 29a, and an adhesive layer 29c is attached to the bottom surface of the base sheet 29a. . Such a flocking sheet member 29 is cut into a belt-like shape, and as shown in FIGS. 2 and 3, an adhesive layer 29c on the bottom surface is disposed along the entire circumference of the front inner peripheral surface of the retainer 1, and the brush The flocked sheet member 29 is bonded to the retainer 1 by the adhesive layer 29c with the bristle material 29b facing the cylindrical frame 20 side.

回動ルーバー２の円筒フレーム２０は、それをリテーナ１内に、中央軸支部３及びボールジョイント８を介して回動可能に装着したとき、植毛シート部材２９のブラシ毛素材２９ｂの先端が円筒フレーム２０の外周面に接触し、回動ルーバー２を上下左右に傾動操作した時、ブラシ毛素材２９ｂの先端が円筒フレーム２０の外周面に摺接するようになっている。 When the cylindrical frame 20 of the rotating louver 2 is rotatably mounted in the retainer 1 via the central shaft support portion 3 and the ball joint 8, the tip of the brush bristle material 29b of the flocking sheet member 29 is the cylindrical frame. When the rotating louver 2 is tilted up and down and left and right, the tip of the brush bristle material 29 b comes into sliding contact with the outer peripheral surface of the cylindrical frame 20.

これにより、リテーナ１と円筒フレーム２０間の隙間を塞ぎつつ、回動操作時のガタツキやゴリゴリ感をなくし、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、且つ回動ルーバー２を閉鎖操作した時、円筒フレーム２０とリテーナ１間の隙間からの風漏れを最小にしている。 As a result, the gap between the retainer 1 and the cylindrical frame 20 can be closed, and rattling and harshness can be eliminated during the turning operation, and the wind direction can be changed by tilting the turning louver with a stable and smooth operation feeling. When the rotating louver 2 is closed, the air leakage from the gap between the cylindrical frame 20 and the retainer 1 is minimized.

一方、回動ルーバー２は、上記構成の如く、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、図８のように、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。 On the other hand, the rotating louver 2 has a cylindrical structure in which the fin body 26 of the movable fin 23 is cylindrical when the movable fins 23 are rotated about their support shafts 24 and 27 to a predetermined angle as described above. The flow path 15 is closed as shown in FIG. 8 in a state substantially parallel to the cross section of the frame 20. 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.

また、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。 Further, 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 are used as in the prior art. 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の小型化に伴い、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 miniaturization of the movable fin 23, the axial length of the state in which 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.

上記のように、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３の仮想線で示すように、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し、流路１５を閉鎖する。このような流路の閉鎖時、回動ルーバー２の円筒フレーム２０の外周部とリテーナ１の内面間が非接触とされるため、その間の隙間から風が漏れやすい。このために、上述の如く、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、図２，３のように、植毛シート部材２９が介挿され、植毛シート部材２９は、その底面の接着材層２９ｃによりリテーナ１の内周面全体に接着されている。 As described above, when the five movable fins 23 of the rotating louver 2 are operated to rotate the operation unit 6 and close the flow path 15, as shown by the phantom lines in FIG. 3, the center line S <b> 2. To a state perpendicular to the air flow direction, that is, a state parallel to a cross section perpendicular to the ventilation direction, and the flow path 15 is closed. When such a flow path is closed, the outer peripheral portion of the cylindrical frame 20 of the rotating louver 2 and the inner surface of the retainer 1 are not in contact with each other, so that wind easily leaks from the gap therebetween. Therefore, as described above, the flocked sheet member 29 is inserted between the outer peripheral surface of the cylindrical frame 20 and the inner peripheral surface of the retainer 1 as shown in FIGS. The entire inner peripheral surface of the retainer 1 is bonded by the adhesive layer 29c on the bottom surface.

上記構成の回動ルーバー２を組み立てる場合、図４、５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. 4 and 5, the operating portion 6 is inserted into the operating portion holding portion 21b at 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４，５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の前部に嵌め込み、係止部１３を係止爪９ａに係止させ、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 at 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 is inserted into the ball joint support portion 11 in the retainer 1, 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, and the locking portion 13 is locked to the locking claw 9a. The assembly of the register is completed.

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空気吹出口９ｂ（図２）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 (FIG. 2), the user can easily hold the operation unit 6 and perform tilting operation or rotation operation. is there.

図２，３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 3, 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 S 2 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, the operation unit 6 is held and turned to the right or left so that the center line S2 is twisted about the axis.

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９ｂ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 9b, the wind is milder than that of the conventional four movable fins. Can be blown.

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、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、図８に示すように、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, each movable fin 23 of the rotation louver 2 rotates about the support shafts 24 and 27 to a state parallel to the vertical plane perpendicular to the center lines S1 and S2 (blocking state of the flow path). As a result, as shown in FIG. 8, the flow path 15 is fully closed, and air flow is blocked.

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７（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７（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。 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 rotation louver 2 is tilted upward as shown in FIG. 7A with respect to the center line S1 of the retainer 1, and thereby the blowing direction is directed obliquely upward. .

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７（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７（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。 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. 7B, and the air 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.

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８のように、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, the five movable fins 23 are turned to a state where the flow path 15 is completely closed as shown in FIG. 8, and the flow path 15 is closed. The

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、円筒フレーム２０とリテーナ内面を非接触で植毛シート部材３９のみを接触させ、ボールジョイント８に支持された状態のボール８１を中心に傾動するので、流路１５の閉鎖時の風漏れを最小にしつつ、製品ごとの寸法誤差に起因したガタツキ、操作荷重のばらつき、及びゴリゴリ感を発生させず、安定した滑らかな操作フィーリングで回動ルーバー２を傾動させ、風向を変えることができる。 As described above, when the rotary louver 2 is tilted and operated in an arbitrary direction by holding the operation portion 6 at the center of the rotary louver 2, the rotary louver 2 contacts the cylindrical frame 20 and the inner surface of the retainer without contacting the flocked sheet member. 39 is brought into contact and tilted about the ball 81 supported by the ball joint 8, so that the air leakage at the time of closing the flow path 15 is minimized, and the play and operation load caused by the dimensional error for each product. Therefore, the rotation louver 2 can be tilted with a stable and smooth operation feeling, and the wind direction can be changed.

図９は、植毛シート部材３９の別の実施形態を示しており、図に示すように、回動ルーバー２における、円筒フレーム２０の後円筒フレーム２２の外周面に、植毛シート部材３９を接着することもできる。この場合、回動ルーバー２は、それを、中央軸支部３及びボールジョイント８を介してリテーナ１内に、回動可能に装着した状態で、後円筒フレーム２２の植毛シート部材３９のブラシ毛素材の先端は、リテーナ１の内周面に接触する。これにより、回動ルーバー２の上下左右への傾動操作時、ブラシ毛素材の先端がリテーナ１の内周面に摺接し、円筒フレーム２０とリテーナ１間の隙間を閉じるように作用する。なお、植毛シート部材３９は、円筒フレーム２０の前円筒フレーム２１の外周面に接着することもできる。 FIG. 9 shows another embodiment of the flocked sheet member 39. As shown in the figure, the flocked sheet member 39 is bonded to the outer peripheral surface of the rear cylindrical frame 22 of the cylindrical frame 20 in the rotating louver 2. You can also. In this case, the rotating louver 2 is a brush bristle material of the flocking sheet member 39 of the rear cylindrical frame 22 in a state where it is rotatably mounted in the retainer 1 via the central shaft support 3 and the ball joint 8. The tip of this contacts the inner peripheral surface of the retainer 1. As a result, when the pivoting louver 2 is tilted up and down and left and right, the tip of the bristle material slides on the inner peripheral surface of the retainer 1 and acts to close the gap between the cylindrical frame 20 and the retainer 1. The flocking sheet member 39 can be bonded to the outer peripheral surface of the front cylindrical frame 21 of the cylindrical frame 20.

このように、植毛シート部材３９を円筒フレーム２０の外周面に接着した回動ルーバー２は、任意の方向に傾動操作したとき、ボールジョイント８に支持された状態でボール８１を中心に、円筒フレーム２０とリテーナ１内面が非接触で傾動し、植毛シート部材３９のブラシ毛素材の先端のみが接触して傾動する。したがって、円筒フレーム２０とリテーナ１間の隙間による風漏れを最小にすることができ、製品ごとの寸法誤差によるガタツキ、操作荷重のばらつき、或いは操作時のゴリゴリ感を防止し、安定した滑らかな操作フィーリングで、回動ルーバー２を傾動・回動させ、風向を変えることができる。 As described above, the rotating louver 2 in which the flocking sheet member 39 is bonded to the outer peripheral surface of the cylindrical frame 20 is tilted in an arbitrary direction and is supported by the ball joint 8 while being centered on the ball 81. 20 and the inner surface of the retainer 1 tilt without contact, and only the tip of the bristle material of the flocking sheet member 39 contacts and tilts. Therefore, it is possible to minimize the air leakage due to the gap between the cylindrical frame 20 and the retainer 1, and to prevent a backlash due to a dimensional error for each product, a variation in operation load, or a harsh feeling during operation, and a stable and smooth operation. With the feeling, the rotating louver 2 can be tilted and rotated to change the wind direction.

なお、上記実施形態の回動ルーバー２には、５枚の可動フィン２３を設けたが、例えば、可動フィンの数を３枚或いは６枚とすることもできる。また、上記操作部６は円環状としたが、別の多角形などの形状にすることもできる。 In addition, although the five movable fins 23 were provided in the rotation louver 2 of the said embodiment, the number of movable fins can also be made into 3 pieces or 6 pieces, for example. Moreover, although the said operation part 6 was made into the annular | circular shape, it can also be made into shapes, such as another polygon.
