- the outer periphery of the knurl 240 is not strictly a circle, but is illustrated as being approximate to a circle for simplicity of explanation.
- the coil spring SP abuts against the inner wall behind the case 10A and presses the slider 220 forward. Therefore, the slider 220 is positioned in front of the case 10A. Therefore, the position is regulated by the shaft 31 whose position is regulated by the first top wall groove 226 and the first bottom wall groove 228 of the slider 220, and the second top wall groove 227 and the second bottom wall groove 229.
- the shaft core 41 and the slider 220 move forward together. Furthermore, the distance between the first ceiling wall groove 16 and the second ceiling wall groove 17 provided in the case 10 ⁇ / b> A held on the upper portion of the slider 220 decreases toward the front.
- the distance between the first base groove 706 and the second base groove 707 provided in the base 70 decreases toward the front. Accordingly, the distance between the roller portion 42 rotatably supported on the shaft core 41 and the knurled 240 rotatably supported on the shaft core 31 is also reduced. That is, the first ceiling wall groove 16 and the first base groove 706 function as a restriction groove that restricts the shaft 31 of the knurled 240 from being movably fitted and the knurled 240 not moving along the groove.

- the wearing force is increased, and the knurl 240 is reliably rotated in accordance with the movement of the code CD.
- the internal gear 261 rotates (rotates) counterclockwise by the force applied from the teeth of the pinion gear 50.
- the internal gear 261 and the internal toothed carrier 260 also rotate (revolve) counterclockwise, and the planetary gear 280 provided on the internal toothed carrier 260 likewise rotates (revolves) counterclockwise.

Will be. Therefore, the sun gear 323 that meshes with the planetary gear 280 inside the planetary gear 280 rotates (rotates) in the opposite direction (counterclockwise) to the rotation of the planetary gear 280. At this time, the rotation of the sun gear 323 is accelerated by the planetary gear 280. Thereby, the weight 340 held by the weight holder 320 with the sun gear rotating together with the sun gear 323 also starts to rotate. As already described, the inner peripheral gear 115 that meshes with the planetary gear 280 outside the planetary gear 280 does not rotate even when the planetary gear 280 rotates because the case 10A and the base 70 are fixed.
- the weight 340 comes into stronger contact with the inner peripheral wall of the case 10A, and the resistance force increases. Thereby, the moving speed of the code CD (the falling speed of the solar radiation shielding member) can be suppressed.
- the tension applied to the cord CD is substantially constant (for example, when the solar radiation shielding member suspended so as to be lifted and lowered by the cord CD on the front side of the braking device 1000 falls freely)
- the tension is applied to the cord CD.
- the moving speed of the cord CD becomes substantially constant where the tension applied, the weight 340, and the resistance force by the inner peripheral wall of the case 10A balance.

1-1<全体構成>
図1に示される遮蔽装置100Aは、中空のヘッドボックス130から複数本のラダーコード123を介して複数段の日射遮蔽部材101が吊下支持され、同ラダーコード123の下端にはボトムレール122が吊下支持されている。ヘッドボックス130は、上面131、底面132、側面133により構成される。そして、その両端にボックスキャップ134が設けられる。また、ヘッドボックス130の内部には、操作棒108内にコードCDを挿通するためのコード出口135が設けられる。ラダーコード123は、日射遮蔽部材101を支持及び回動可能なものであればその構成は限定されず、例えば、互いに分離された2本の縦糸を備え、一方の縦糸がスラットの一方の縁に取着され、他方の縦糸がスラットの他方の縁に取着されるような構成であってもよい。
次に、図2~図22を用いて、制動装置1000について説明する。本実施形態に係る制動装置1000は、コードの移動を制動する制動装置である。具体的には、本実施形態に係る制動装置1000では、運動変換部に係る機構と抵抗付与部に係る機構が略垂直に位置するように設けられる。本実施形態では、運動変換部は、コードCDの移動を他の部材の運動に変換するものである。また、抵抗付与部は、コードCDが一方向に相対移動するときに、コードCDの移動に伴って抵抗力を発生させるものである。ここで、本実施形態においては、スライダー220、コイルスプリングSP、軸芯41及びローラ部42からなるアイドルローラ40、ローレット240、ピニオンギア50、軸芯31、ワッシャー241、内歯付キャリア260及び遊星歯車280が、運動変換部を構成し、ウェイト340、太陽歯車付ウェイトホルダ320及びケース10Aが、抵抗付与部を構成する。
図4(a),(b)に示されるように、整列部材200は、コードCDを挿通し、コードCDの向きを整えるものである。また、複数のコードCDを互いに同じ向きに整列させるものである。整列部材200は、例えば、プラスチック等の樹脂で形成することができる。ここで、図4(a)に示されるように、矢印の向きをそれぞれ前後、左右、上下とする。すなわち、第1天壁溝16と第2天壁溝17の距離が狭くなる向きを前方とし、左右方向(幅方向)、上下方向を定める。
次に、図11(a),(b)及び図12を用いてケース10Aについて説明する。なお、以下、図12において左向きを前方、右向きを後方、上向きを右側、下向きを左側として説明する。ケース10Aは、ベース70とともに筐体を構成し、その内部にスライダー220、コイルスプリングSP、軸芯41及びローラ部42からなるアイドルローラ40、ローレット240、ピニオンギア50、軸芯31、ワッシャー241、内歯付キャリア260、遊星歯車280、プレート300、太陽歯車付ウェイトホルダ320及びウェイト340を保持する。
次に、図13を用いてスライダー220について説明する。スライダー220は、アイドルローラ40及びローレット240を内部に保持し且つアイドルローラ40及びローレット240と共に移動する移動部材に相当する。スライダー220は、天壁部221と、天壁部221に連結される後側壁部222及び前側壁部224と、後側壁部222及び前側壁部224のそれぞれに連結される底壁部223とを有する。
次に、図3及び図15を用いて、アイドルローラ40、ローレット240及びピニオンギア50について説明する。
次に、図2及び図15を用いて内歯付キャリア260及び遊星歯車280について説明する。本実施形態では、内歯付キャリア260は、平面視において略ドーナツ形状である。内歯付キャリア260は、円柱部264から平面視において外側に突出するフランジ262を備える。
次に、太陽歯車付ウェイトホルダ320及びウェイト340について、図2及び図15を用いて説明する。ウェイト340は、ケース10A内のベース70に載置され且つ制動対象からの回転入力により径方向外側に遠心力が加えられる遠心拡張部の一例である。太陽歯車付ウェイトホルダ320は、リング状のリング部324の外方に向かって、凸部321及び凹部322が交互に並んで形成される。ここで、凸部321は、太陽歯車付ウェイトホルダ320の自転の際にウェイト340の側面と当接する部材である。図2に示されるように、リング部324の外側の外周面には、遊星歯車280と歯合する太陽歯車323が、回転軸が凸部321の延在方向と略垂直方向を向くように設けられる。そして、それぞれの凹部322には、ウェイト340が配置される。つまり、太陽歯車付ウェイトホルダ320は、制動装置1000の組み立て時において、凸部321を境としてそれぞれの凹部322内にウェイト340を保持する部材であるとも言える。なお、ウェイト340の数は任意であるが、回転時におけるバランスの観点から等間隔であることが好ましい。なお、本実施形態では、一例として8つのウェイト340を用いている。したがって、凸部321及び凹部322もそれぞれ8つずつ設けられている。すなわち、凹部322は、それぞれが等間隔且つ太陽歯車付ウェイトホルダ320の自転中心から等距離に配置されることとなる。
次に、図2、図3、図5(b)及び図15を用いて、ベース70について説明する。図2及び図3に示されるように、ベース70の略中央には、周囲より嵩高くなっており、下側が凹んでいる円柱部708が設けられる。そして、図2及び図5(b)に示されるように、円柱部708の上面に第1ベース溝706、第1ガイド壁706A、第2ベース溝707、第2ガイド壁707Aが設けられる。
ことにより、軸芯31及び軸芯41の下端が、制動装置1000を載置する載置面と接触することを防ぎ、軸芯31及び軸芯41の下端を適切に挿通することが可能となる。
次に、これら各部材を組み立てた状態について、図4~図8を用いて説明する。図4は、これらの部材を組み合わせて構成された制動装置1000の組立図である。図4に示されるように、制動装置1000の外観は、ケース10A及びベース70が接続された筐体と、ケース10Aの上方から被せるようにして配置された整列部材200からなる。かかる組立は、図2及び図3に示されるように、各部材同士の中心軸を上下方向に重ねあわせた状態でなされる。具体的には、内歯付キャリア260と、ウェイト340を保持した太陽歯車付ウェイトホルダ320が、プレート300を介して組み立てられる。このとき、内歯付キャリア260に設けられた遊星歯車280と、太陽歯車付ウェイトホルダ320に設けられた太陽歯車323とが互いに歯合するようにする。
次に、図6~図8を用いて、組立状態における内部構造について説明する。図6は、図4の状態から整列部材200及びケース10Aを取り外した状態における斜視図である。図6に示されるように、スライダー220の上方に軸芯31及び軸芯41が突出している。また、軸芯31は、第1天壁溝226内においてスライダー220の幅方向に動きが規制される。同様に、軸芯41は、第2天壁溝227内においてスライダー220の幅方向に動きが規制される。なお、図示を省略しているコードCDは、スライダー220の貫通孔225に縦に整列された状態でスライダー220の前後方向に挿通される。
次に、図18を用いて本実施形態に係る制動装置1000の動作について説明する。図18(a)はコードCDに何ら張力が与えられない状態(定常状態)、図18(b)はコードCDに張力が与えられ、ローレット240及びローラ部42でコードCDが挟着された状態(挟着状態)、図18(c)は図18(a)から図18(b)へ状態変化する際における各部材の回転方向をまとめた図である。なお、図18(a),(b)はともに、図16と同様に、図4(c)のA-A線切断部断面図である。ここで、説明の都合上、かかる断面図には現れないローラ部42の外周を軸芯41の周囲に、ローレット240の外周を軸芯31の周囲に重ねて表示した。なお、ローレット240の外周は厳密には円形ではないが、説明の簡略化のため、円形に近似して図示している。
次に、図21~図23を用いて、本発明の第2実施形態に係る運動変換部について説明する。図21に示されるように、第2実施形態では、ローレット240及びローラ部42が、それぞれの軸芯31及び軸芯41を介して連結される。ここで、かかる連結方法は任意であり、例えば、図21(a)に示されるように、一対のプレート800を用いてもよい。ここで、第2実施形態では、プレート800は略矩形であり、例えば金属製のプレート800を用いることができる。また、プレート800の軸芯31及び軸芯41に対応する箇所には貫通孔801が設けられ、軸芯31及び軸芯41を貫通孔801に挿入することによりローレット240とローラ部42を連結することができる。なお、紐状部材900を用いる場合、図22に示されるように、コードCDの移動時においてローレット240とローラ部42が逆向きに回転するため、紐状部材900をクロスする構成としている。ここで、図22は、図21(b)の部材がコードCDを挟着する状態を矢印Z方向から見た模式図である。
次に、図24を用いて、本発明の第3実施形態に係る他の運動変換部について説明する。図24に示されるように、第3実施形態に係るケース10Cには、ローレット240の直径よりわずかに大きい収容空間93が形成される。ここで、収容空間93は、断面視において円弧形状と半直線形状を組み合わせた形状をなしている。したがって、ローレット240は収容空間93内で自由に移動することができる。また、収容空間93には、挟着案内斜面93a、及び解除側規制面93dが形成される。
次に、図25を用いて、本発明の第4実施形態に係る運動変換部について説明する。第4実施形態は、第2実施形態を変形した構成である。そのため、以下では第2実施形態からの変更点についてのみ説明する。図23に示されるように、第2実施形態では、重力gを利用して軸芯31及びローレット240が下方に降下する構成としており、重力gを付勢部材として利用していたと言うことができる。これに対し、第4実施形態では、図25に示されるように、軸芯31は、連結部材170により固定軸160と連結される。ここで、連結部材170は、例えば図21のプレート800を利用することができる。そして、連結部材170にばね150を取り付けている。これにより、固定軸160を中心として、連結部材170が矢印g方向に付勢されることにより、軸芯31及びローレット240を矢印g方向に付勢している。
次に、図26を用いて、第4実施形態の変形例について説明する。図26に示されるように、第1挟着部材(ローレット240)及び第2挟着部材(挟着平面132s)により、一対の挟着部材が構成される。ケース10Bは、ローレット240を内包する。つまり、ケース10Bは、一対の挟着部材の少なくとも一方を内包する。ここで、図中の破線CBは、ケース10Bの底面を表すものである。さらに、ケース10Bは、第1側壁孔119Aを備える。
次に、図28~図34を用いて、第5実施形態に係る制動装置5000を説明する。本実施形態に係る制動装置5000は、図28等に示されるように、運動変換部DT及び抵抗付与部RAが並列配置された構成となっている。以下、本実施形態の概略を説明する。
更に、図35に示されるように、本変形例に係る制動装置5100は、解放方向にコードCDが移動させるときを除いてガイド軸31Cが第1位置に位置するように、ケース10Aaに設けられた固定部441Aとガイド軸31Cとの間に、コイル部が回転軸31Bに巻回された付勢手段としてのトーションばね31Cbを配置し、トーションばね31Cbによってガイド軸31Cを付勢してもよい。ここで、本変形例では、ガイド溝31Caが規制溝に相当し、挟着部材(キャッチローラ32A)の初期状態における挟着位置を超えて延在する。なお、図35(a)では、所定の挟着位置を破線の円で示している。
次に、図36及び図37を用いて、第5実施形態の変形例2に係る制動装置5200を説明する。本変形例に係る制動装置5200は、図36及び図37に示されるように、運動変換部DT及び抵抗付与部RAが左右方向(紙面に垂直な方向)に並列配置された構成となっている。以下、本変形例の概略を説明する。
次に、図38~図40を用いて、第5実施形態の変形例3に係る制動装置5300を説明する。本変形例に係る制動装置5300は、図36及び図37に示されるように、運動変換部DT及び抵抗付与部RAが左右方向(紙面に垂直な方向)に並列配置された構成となっている。以下、本変形例の概略を説明する。
次に、図41~図43を用いて、本発明の第6実施形態に係る制動装置6000について説明する。本実施形態の制動装置6000は第2実施形態に記載の制動装置1000と類似している。しかしながら、本実施形態の制動装置6000は、一対の挟着部材の各軸心の軸方向両端側が一対のリンクプレート721,722で構成されるリンク機構720により保持される点が、主な相違点となっている。なお、以下の説明において、第1実施形態と同じ構成の部材には同じ符号を付すとともに、構成の異なる部分について主に説明する。
