撓み片部３２ｂの付け根側には、被接続部１１ａ３における本体片部１１ａ１寄りの部分に接する接触部３２ｂ１を有する（図３参照）。 On the base side of the flexible piece portion 32b, there is a contact portion 32b1 in contact with the portion of the connected portion 11a3 closer to the main body piece portion 11a1 (see FIG. 3).

括れ部３２ｃは、当接片部３２ａと撓み片部３２ｂとの間に位置し、当接片部３２ｃの上下方向の首振り運動を容易にする。
この括れ部３２ｃは、当接片部３２ａと撓み片部３２ｂの間の下側の内角部分を凹欠状に形成してなる。この括れ部３２ｃの厚みｔ２は、撓み片部３２ｂの厚みｔ１よりも薄い。 The constricted portion 32c is located between the abutting piece portion 32a and the bending piece portion 32b, and facilitates the vertical swinging motion of the abutting piece portion 32c.
The constricted portion 32c is formed with a concave inner angle portion between the contact piece portion 32a and the flexible piece portion 32b. The thickness t2 of the constricted portion 32c is thinner than the thickness t1 of the flexible piece portion 32b.

また、ガイドレール２０は、開閉体１０の左右両側にそれぞれ設けられる。
各ガイドレール２０は、開閉体１０の幅方向の端部側を、開口部に挿入し横断面凹状に囲むようにして、当接対象部位Ｇと収納部４０の間にわたって上下方向へ連続している。 Further, the guide rails 20 are provided on both the left and right sides of the opening / closing body 10, respectively.
Each guide rail 20 is continuous in the vertical direction between the contact target portion G and the storage portion 40 so that the end side in the width direction of the opening / closing body 10 is inserted into the opening and surrounded by a concave cross section.

また、収納部４０は、図１に示すように、開閉体１０を出没させるための開口部を下部に形成した収納ケース４１内に、開閉体１０を巻き取ったり繰出したりする巻取軸４２と、該巻取軸４２をチェーン及びスプロケット等の動力伝達機構を介して駆動回転したり制動したりする開閉機４３と、図示しない制御回路とを備える。 Further, as shown in FIG. 1, the storage portion 40 includes a winding shaft 42 for winding and feeding the opening / closing body 10 in a storage case 41 having an opening for infesting the opening / closing body 10 at the lower portion. A switch 43 for driving, rotating, and braking the take-up shaft 42 via a power transmission mechanism such as a chain and a sprocket, and a control circuit (not shown).

巻取軸４２は、その軸方向を開閉体幅方向へ向けた円筒状に形成され、外周面に、開閉体１０の上端部を接続している。そして、この巻取軸４２は、一方向へ回転することで、外周面に開閉体１０を巻き重ねてゆき（図４及び図５参照）、逆方向へ回転することで、同開閉体１０を下方へ繰出してゆく。 The take-up shaft 42 is formed in a cylindrical shape with its axial direction facing the opening / closing body width direction, and the upper end portion of the opening / closing body 10 is connected to the outer peripheral surface. Then, the take-up shaft 42 winds the opening / closing body 10 on the outer peripheral surface by rotating in one direction (see FIGS. 4 and 5), and rotates in the opposite direction to rotate the opening / closing body 10. It goes down.

次に、上記構成の開閉装置１について、その特徴的な作用効果を詳細に説明する（図４及び図５参照）。
開閉体１０が巻取軸４２に巻き取られると、巻取軸４２の外周面に対し、先ず、緩衝材３０の突端側が当接し、緩衝材３０が徐々に変形した後に、被接続部１１ａ３の当接部１１ａ３１が当接する。
次に、巻き重ねられた際に内側となる開閉体１０の外面に対し、先ず、緩衝材３０の突端側が当接し、緩衝材３０が徐々に変形した後に、被接続部１１ａ３の当接部１１ａ３１が当接する。 Next, the characteristic operation and effect of the switchgear 1 having the above configuration will be described in detail (see FIGS. 4 and 5).
When the opening / closing body 10 is wound around the take-up shaft 42, the tip side of the cushioning material 30 first comes into contact with the outer peripheral surface of the take-up shaft 42, the cushioning material 30 is gradually deformed, and then the connected portion 11a3 is connected. The contact portion 11a31 comes into contact with the contact portion 11a31.
Next, the tip side of the cushioning material 30 first comes into contact with the outer surface of the opening / closing body 10 which becomes the inner side when the cushioning material 30 is rolled up, and after the cushioning material 30 is gradually deformed, the contact portion 11a31 of the connected portion 11a3 Abuts.

前述した緩衝材３０の変形について、詳細に説明すれば、緩衝材３０は、先ず、当接片部３２ａの下端側部分３２ａ１を、内側の巻取軸４２又は開閉体１０の外面に当接する。
次に、緩衝材３０は、当接片部３２ａを首振り運動するように弾性変形させるとともに、撓み片部３２ｂを巻取軸径方向外側へ弾性的に撓ませる。前記首振り運動は、異なる表現をすれば、当接片部３２ａが括れ部３２ｃの近傍を支点にして回転する運動である。
そして、当接片部３２ａの上端側部分３２ａ２が、巻取軸４２又は開閉体１０の外面に当接し、さらに、被接続部１１ａ３が、巻取軸４２又は開閉体１０の外面に当接する。
この状態では、平坦状の当接片部３２ａの略全面が、巻取軸４２又は開閉体１０の外面に面接触する（図５参照）。 The deformation of the cushioning material 30 described above will be described in detail. First, the cushioning material 30 abuts the lower end side portion 32a1 of the contact piece portion 32a on the inner winding shaft 42 or the outer surface of the opening / closing body 10.
Next, the cushioning material 30 elastically deforms the contact piece portion 32a so as to swing, and elastically bends the bending piece portion 32b outward in the winding shaft radial direction. In other words, the swinging motion is a motion in which the contact piece portion 32a rotates with the vicinity of the constricted portion 32c as a fulcrum.
Then, the upper end side portion 32a2 of the contact piece portion 32a abuts on the outer surface of the take-up shaft 42 or the opening / closing body 10, and the connected portion 11a3 abuts on the outer surface of the take-up shaft 42 or the opening / closing body 10.
In this state, substantially the entire surface of the flat contact piece portion 32a comes into surface contact with the outer surface of the take-up shaft 42 or the opening / closing body 10 (see FIG. 5).

また、開閉体１０が巻取軸４２から繰り出されて閉鎖動作する際は、各緩衝材３０が元の状態に弾性的に復元する。 Further, when the opening / closing body 10 is unwound from the take-up shaft 42 and closes, each cushioning material 30 is elastically restored to the original state.

このように、各スラット１１ａの内面が、その内側の巻取軸４２外周面又はスラット１１ａ表面に接触する際、先ず、緩衝材３０が、下端側部分３２ａ１と上端側部分３２ａ２とを順次に当接させるようにして徐々に弾性変形し、この後で、被接続部１１ａ３の当接部１１ａ３１がスラット１１ａ表面にゆっくりと当接する。したがって、これら段階的な当接により、騒音や振動等の衝撃を軽減することができる。 As described above, when the inner surface of each slat 11a comes into contact with the inner peripheral surface of the take-up shaft 42 or the surface of the slat 11a, the cushioning material 30 first sequentially hits the lower end side portion 32a1 and the upper end side portion 32a2. It is gradually elastically deformed so as to be in contact with each other, and after that, the abutting portion 11a31 of the connected portion 11a3 slowly abuts on the surface of the slat 11a. Therefore, impacts such as noise and vibration can be reduced by these stepwise contact.

しかも、スラット１１ａ毎に各緩衝材３０が上側の接続部１１ａ２と下側の被接続部１１ａ３の間の横向き凹状部分に入り込むように撓み変形するため、開閉体１０の巻径の増大を抑制することができる。 Moreover, since each cushioning material 30 bends and deforms so as to enter the laterally concave portion between the upper connecting portion 11a2 and the lower connected portion 11a3 for each slat 11a, the increase in the winding diameter of the opening / closing body 10 is suppressed. be able to.

また、緩衝材３０がその内側の部材（巻取軸４２又はスラット１１ａ）を押圧する際の押圧力は、被接続部１１ａ３がその内側の部材に当接した後、略一定の低い押圧力に保たれる。このため、各スラット１１ａの外側の面に、緩衝材３０による圧痕等が付くのを軽減することができる。
したがって、緩衝材３０を、ガイドレール２０内に隠すように配置する必要がなく、幅方向において撓みの大きい開閉体１０の幅方向中央寄りに露出して、開閉体１０の巻重ね音等を効果的に低減することができる。 Further, the pressing force when the cushioning material 30 presses the inner member (winding shaft 42 or slats 11a) becomes a substantially constant low pressing force after the connected portion 11a3 abuts on the inner member. Be kept. Therefore, it is possible to reduce the indentation caused by the cushioning material 30 on the outer surface of each slats 11a.
Therefore, it is not necessary to arrange the cushioning material 30 so as to hide it in the guide rail 20, and it is exposed toward the center of the opening / closing body 10 having a large deflection in the width direction, and the winding sound of the opening / closing body 10 is effective. Can be reduced.

その上、上記構成の緩衝材３０は、既存のスラット１１ａに対し容易に装着することができる。このため、既設されている開閉装置１であっても、緩衝材３０を装着して低騒音化及び低振動化をはかることができる。 Moreover, the cushioning material 30 having the above configuration can be easily attached to the existing slats 11a. Therefore, even with the existing switchgear 1, the cushioning material 30 can be attached to reduce noise and vibration.

＜第二の実施態様＞ <Second embodiment>

次に、上記構成の変形例について説明する。
以下の変形例は、上記開閉装置１の構成の一部を変更したものであるため、主にその変更部分について詳述し、上記開閉装置１と同一となる構成には同一の符号を付けて重複する詳細説明を省略する、 Next, a modified example of the above configuration will be described.
Since the following modification is a modification of a part of the configuration of the switchgear 1, the changed portion is mainly described in detail, and the same configuration as the switchgear 1 is designated by the same reference numeral. Omitting duplicate detailed explanations,

図６～図９に示す態様は、上記緩衝材３０を、後述する緩衝材５０に置換したものである。 In the embodiment shown in FIGS. 6 to 9, the cushioning material 30 is replaced with the cushioning material 50 described later.

緩衝材５０は、開閉体１０の嵌合凹部１１ａ４に嵌り合って固定される被固定部５１と、この被固定部５１から接続部１１ａ２側であって斜め反本体片部１１ａ１側（図７によれば上斜め左側）へ突出して巻き重ねられた際の内外の開閉体１０，１０の間に挟まれて弾性変形する変形部５２とを一体に有し、開閉体幅方向へ連続している（図６参照）。この緩衝材５０は、緩衝材３０と同様の弾性材料から形成される。 The cushioning material 50 has a fixed portion 51 that is fitted and fixed to the fitting recess 11a4 of the opening / closing body 10, and a connecting portion 11a2 side from the fixed portion 51 and an oblique anti-main body piece portion 11a1 side (in FIG. 7). According to this, it has a deformed portion 52 that is sandwiched between the inner and outer opening / closing bodies 10 and 10 when it is rolled up so as to project to the upper diagonal left side) and elastically deforms, and is continuous in the opening / closing body width direction. (See FIG. 6). The cushioning material 50 is formed of the same elastic material as the cushioning material 30.

被固定部５１は、嵌合凹部１１ａ４に嵌り合った状態で、開閉体厚さ方向へ拡げる弾性復元力を保持している。
この被固定部５１は、嵌合凹部１１ａ４における入口部分１１ａ４Ｘよりも底側の部分に対応する開閉体厚さ方向の幅が、入口部分１１ａ４Ｘに対応する開閉体厚さ方向の幅よりも大きい（図７参照）。 The fixed portion 51 holds an elastic restoring force that expands in the thickness direction of the opening / closing body in a state of being fitted into the fitting recess 11a4.
The width of the fixed portion 51 in the opening / closing body thickness direction corresponding to the portion on the bottom side of the inlet portion 11a4X in the fitting recess 11a4 is larger than the width in the opening / closing body thickness direction corresponding to the inlet portion 11a4X ( See FIG. 7).

この被固定部５１の下端部には、嵌合凹部１１ａ４の底部に対向する部分に、開閉体幅方向へわたるスリット部５１ａが設けられる。
このスリット部５１ａは、被固定部５１の下端面に、縦断面逆凹状に形成され、開閉体幅方向へ長尺状に連続しており、上記緩衝材３０のスリット部３１ａと略同様の作用効果を奏する。 At the lower end of the fixed portion 51, a slit portion 51a extending in the width direction of the opening / closing body is provided at a portion facing the bottom of the fitting recess 11a4.
The slit portion 51a is formed on the lower end surface of the fixed portion 51 in an inverted concave shape in a vertical cross section, and is continuous in a long shape in the width direction of the opening / closing body, and has substantially the same function as the slit portion 31a of the cushioning material 30. It works.

また、変形部５２は、巻き重ねられた際に内側となる開閉体１０の表面に対し当接する突端側部分を略平坦状に形成した当接片部５２ａと、この当接片部５２ａよりも被固定部５１側で開閉体開閉方向へ弾性変形可能な中空変形部５２ｂと、当接片部５２ａと中空変形部５２ｂの間に位置する括れ部５２ｃとを一体に有する。 Further, the deformed portion 52 is more than the abutting piece portion 52a in which the tip side portion that abuts on the inner surface of the opening / closing body 10 when rolled up is formed to be substantially flat, and the abutting piece portion 52a. It integrally has a hollow deformed portion 52b that can be elastically deformed in the opening / closing direction of the opening / closing body on the fixed portion 51 side, and a constricted portion 52c located between the contact piece portion 52a and the hollow deformed portion 52b.

当接片部５２ａは、巻き重ねられた際に内側となる開閉体１０に対し当接するように、被接続部１１ａ３よりも反本体片部１１ａ１側（図７によれば左側）へ突出しており、その突端側部分を略平坦状に形成している。
この当接片部５２ａは、図８及び図９に示すように、内側となる開閉体１０に対し、開閉方向の一端側（図示例によれば下端側）を当接した後に首振り運動して他端側（図示例によれば上端側）を当接する。 The contact piece portion 52a protrudes from the connected portion 11a3 toward the anti-main body piece portion 11a1 side (left side according to FIG. 7) so as to abut against the opening / closing body 10 which is inside when the contact piece portion 52a is wound. , The tip side portion is formed in a substantially flat shape.
As shown in FIGS. 8 and 9, the contact piece portion 52a abuts on one end side (lower end side according to the illustrated example) in the opening / closing direction with respect to the opening / closing body 10 on the inner side, and then swings. Abuts on the other end side (upper end side according to the illustrated example).

中空変形部５２ｂは、内部が中空の縦断面略環状に形成される（図７参照）。
この中空変形部５２ｂには、嵌合凹部１１ａ４の外側で被接続部１１ａ３に対し面接触する接触部５２ｂ１と、嵌合凹部１１ａ４の外側で本体片部１１ａ１に対し面接触する接触部５２ｂ２とが設けられる。 The hollow deformed portion 52b is formed in a substantially annular shape with a hollow vertical cross section (see FIG. 7).
The hollow deformed portion 52b has a contact portion 52b1 that makes surface contact with the connected portion 11a3 outside the fitting recess 11a4 and a contact portion 52b2 that makes surface contact with the main body piece portion 11a1 outside the fitting recess 11a4. It will be provided.

括れ部５２ｃは、当接片部５２ａと中空変形部５２ｂとの間に位置し、当接片部５２ａ及び中空変形部５２ｂよりも、開閉体開閉方向の寸法が小さく設定される。この括れ部５２ｃは、当接片部５２ａの上下方向の首振り運動を容易にする。 The constricted portion 52c is located between the contact piece portion 52a and the hollow deformed portion 52b, and is set to have a smaller dimension in the opening / closing direction than the contact piece portion 52a and the hollow deformed portion 52b. The constricted portion 52c facilitates a vertical swinging motion of the contact piece portion 52a.

次に、緩衝材５０を装着した開閉装置１について、その特徴的な作用効果を説明する（図８及び図９参照）。
開閉体１０が巻取軸４２に巻き取られると、巻取軸４２の外周面に対し、先ず、緩衝材５０の突端側が当接し、緩衝材５０が徐々に変形した後に、被接続部１１ａ３の当接部１１ａ３１が当接する。
次に、巻き重ねられた際に内側となる開閉体１０の外面に対し、先ず、緩衝材５０の突端側が当接し、緩衝材５０が徐々に変形した後に、被接続部１１ａ３の当接部１１ａ３１が当接する。 Next, the characteristic action and effect of the switchgear 1 equipped with the cushioning material 50 will be described (see FIGS. 8 and 9).
When the opening / closing body 10 is wound around the take-up shaft 42, the tip side of the cushioning material 50 first comes into contact with the outer peripheral surface of the take-up shaft 42, the cushioning material 50 is gradually deformed, and then the connected portion 11a3 is connected. The contact portion 11a31 comes into contact with the contact portion 11a31.
Next, the tip side of the cushioning material 50 first comes into contact with the outer surface of the opening / closing body 10 which becomes the inner side when the cushioning material 50 is rolled up, and after the cushioning material 50 is gradually deformed, the contact portion 11a31 of the connected portion 11a3 Abuts.

詳細に説明すれば、緩衝材５０は、先ず、当接片部５２ａの下端側部分５２ａ１を、内側の巻取軸４２又は開閉体１０の外面に当接する。
次に、緩衝材５０は、当接片部５２ａを首振り運動するように弾性変形させるとともに、中空変形部５２ｂを巻取軸径方向外側へ弾性的に圧縮させる。そして、緩衝材５０の上端側部分５２ａ２が、巻取軸４２又は開閉体１０の外面に当接し、さらに、被接続部１１ａ３が、巻取軸４２又は開閉体１０の外面に当接する。
この状態では、平坦状の当接片部５２ａの略全面が、巻取軸４２又は開閉体１０の外面に面接触する（図９参照）。 More specifically, the cushioning material 50 first abuts the lower end side portion 52a1 of the contact piece portion 52a on the inner winding shaft 42 or the outer surface of the opening / closing body 10.
Next, the cushioning material 50 elastically deforms the contact piece portion 52a so as to swing, and elastically compresses the hollow deformed portion 52b outward in the winding shaft radial direction. Then, the upper end side portion 52a2 of the cushioning material 50 abuts on the outer surface of the take-up shaft 42 or the opening / closing body 10, and the connected portion 11a3 abuts on the outer surface of the take-up shaft 42 or the opening / closing body 10.
In this state, substantially the entire surface of the flat contact piece portion 52a comes into surface contact with the outer surface of the take-up shaft 42 or the opening / closing body 10 (see FIG. 9).

また、開閉体１０が巻取軸４２から繰り出されて閉鎖動作する際は、各緩衝材５０が元の状態に弾性的に復元する。 Further, when the opening / closing body 10 is unwound from the take-up shaft 42 and closes, each cushioning material 50 is elastically restored to the original state.

このように、緩衝材５０を用いた開閉装置１によれば、緩衝材３０を用いた場合と略同様の作用効果を奏し、騒音及び振動を効果的に低減することができ、緩衝材５０の組付け性も良好である。 As described above, according to the switchgear 1 using the cushioning material 50, the action and effect are substantially the same as those in the case of using the cushioning material 30, noise and vibration can be effectively reduced, and the cushioning material 50 can be used. The assembling property is also good.

さらに、他例としては、巻き重ねられる際に内側となる開閉体又は巻取軸の表面に対し、平坦状の上記当接片部を、略面接触となるように当接させる態様とすることも可能である。 Further, according to the above embodiment, the contact piece portion abuts on the lower end side with respect to the surface of the opening / closing body or the take-up shaft which is inside when the contact piece is wound, and then swings to move the upper end side. Although the contact is made (see FIGS. 4 and 5), as another example of this contact piece, the upper end side is in contact with the surface of the opening / closing body or the take-up shaft which is inside when the parts are wound. It is also possible to make a swinging motion and then abut the lower end side.

It is also possible to have an embodiment, an embodiment in which the cushioning material is provided in a long shape over substantially the entire length of each slats 11a, and the like.

また、上記実施態様によれば、上記変形部は、開閉体１０が巻き重ねられていない状態で、その一部が、被接続部１１ａ３及び接続部１１ａ２よりも開閉体厚さ方向の一方へ突出するようにしたが、他例としては、上記変形部を、被接続部１１ａ３又は接続部１１ａ２よりも開閉体厚さ方向の一方へ突出する構成とすることも可能である。
すなわち、上記緩衝材を被接続部１１ａ３寄りに設けた場合には、開閉体１０が巻き重ねられていない状態で、上記変形部の一部を被接続部１１ａ３よりも開閉体厚さ方向の一方へ突出させ、同変形部の一部を接続部１１ａ２よりも突出しないようにすることが可能である。

However, as another example, the deformed portion may be configured to protrude from the connected portion 11a3 or the connecting portion 11a2 in one direction in the thickness direction of the opening / closing body.
That is, when the cushioning material is provided closer to the connected portion 11a3, a part of the deformed portion is partially formed in the opening / closing body thickness direction with respect to the connected portion 11a3 in a state where the opening / closing body 10 is not wound. It is possible to project the deformed portion to the position so that a part of the deformed portion does not protrude from the connecting portion 11a2.

It is possible to have a plurality of either one or both of them in the width direction of the opening / closing body.
That is, as another example other than the illustrated example, a mode in which a plurality of the deformed portions arranged in the opening / closing body width direction are connected to the single fixed portion, or a plurality of the fixed portions arranged in the opening / closing body width direction. On the other hand, it is possible to have a mode in which a single number of the deformed portions are connected, a mode in which a plurality of the deformed portions arranged in the width direction of the opening / closing body are connected to a plurality of the fixed portions arranged in the width direction of the opening / closing body, and the like. ..

It is possible to form a plurality of the deformed portions short in the width direction of the opening / closing body.

また、上記実施態様によれば、上記被固定部と上記変形部を同材質とし一体に形成したが、他例としては、上記被固定部と上記変形部を異なる材質にすることも可能である。この場合、上記嵌合凹部に対する上記緩衝材の接続強度を向上する観点から、好ましくは、上記被固定部を上記変形部よりも硬質な材料（例えば、上記変形部よりも硬質な合成樹脂材料や、ゴム、金属材料等）とする。これら被固定部と変形部を一体化する手段は、二色成形や、接着、溶着、嵌合等とすればよい。 Further, according to the above embodiment, the fixed portion and the deformed portion are integrally formed of the same material, but as another example, the fixed portion and the deformed portion may be made of different materials. ..
