ところで、上記従来の開閉装置によれば、開閉体を巻き取る際に、該開閉体の内面と外面とが当接して、騒音や振動等を発生するおそれがある。
そこで、前記内面と前記外面の間に緩衝材を挟むことが考えられるが、緩衝材が安易に外れることのないように工夫を要する。 However, with the above-mentioned conventional opening and closing device, when the opening and closing body is wound up, the inner and outer surfaces of the opening and closing body may come into contact with each other, which may cause noise, vibration, and the like.
In view of this, it is conceivable to sandwich a cushioning material between the inner and outer surfaces, but this requires some ingenuity to ensure that the cushioning material does not easily come off.

このような課題に鑑みて、本発明は、以下の構成を具備するものである。
空間を仕切るようにして閉鎖動作するとともに逆方向へ開放動作して巻き重ねられる開閉体と、巻き重ねられた際の前記開閉体の間に挟まれる緩衝材と、前記開閉体を幅方向の両側で開閉方向へ案内するガイドレールとを備え、前記緩衝材は、前記開閉体に固定された被固定部と、巻き重ねられた際の前記開閉体の間に挟まれて弾性変形する変形部とを一体的に具備し、前記被固定部が前記変形部よりも硬質な材料により形成され、前記開閉体は、幅方向へ長尺なスラットを開閉方向に複数接続してなり、前記各スラットには、本体片部と、前記本体片部の開放方向側で開閉体厚さ方向の一方へ突出した接続部と、前記本体片部の閉鎖方向側で前記一方へ突出して他のスラットの接続部に接続された被接続部と、対向する内面間に前記被固定部を嵌め合わせた嵌合凹部とが設けられ、前記被固定部は、一方側の前記内面に対向部分を圧接した第一の突片部と、他方側の前記内面に対向部分を圧接した第二の突片部とを有することを特徴とする開閉装置。
In view of the above problems, the present invention has the following configuration.
an opening/closing body that is wound up and closed while opening in the opposite direction to divide a space; a cushioning material that is sandwiched between the opening/closing bodies when wound up; and a guide rail that guides the opening/closing body in the opening and closing direction on both sides of the width direction, the cushioning material integrally comprising a fixed portion fixed to the opening/closing body and a deforming portion that is sandwiched between the opening/closing bodies when wound up, and the fixed portion is formed of a material that is harder than the deforming portion , the opening/closing body being formed by connecting a plurality of slats that are long in the width direction in the opening and closing direction, each of the slats having a main body piece, a connecting portion that protrudes to one side in the opening/closing body thickness direction on the opening direction side of the main body piece, a connected portion that protrudes to the one side on the closing direction side of the main body piece and is connected to the connecting portion of another slat, and a fitting recess into which the fixed portion is fitted between opposing inner surfaces, and the fixed portion has a first protruding portion whose opposing portion is pressed against the inner surface on one side, and a second protruding portion whose opposing portion is pressed against the inner surface on the other side .

本発明は、以上説明したように構成されているので、開閉体を巻き取る際の振動及び騒音を効果的に緩和することができる上、緩衝材が外れてしまうのを防ぐことができる。 As the present invention is configured as described above, it is possible to effectively reduce vibration and noise when winding up the opening and closing body, and also to prevent the cushioning material from coming off.

＜具体的実施態様＞
次に、上記特徴を具備した具体的な実施態様について、図面に基づいて詳細に説明する。
以下の説明において、「開閉体厚さ方向」とは、閉鎖状態の開閉体の厚さ方向を意味する。また、「開閉体幅方向」とは、開閉体の開閉方向と略直交する方向であって、開閉体の厚さ方向ではない方向を意味する。
また、「開閉体開閉方向」とは、開閉体が空間を仕切るようにして閉鎖したり開放したりするスライド方向を意味する。 <Specific embodiment>
Next, specific embodiments having the above-mentioned features will be described in detail with reference to the drawings.
In the following description, the term "thickness direction of the opening/closing body" refers to the thickness direction of the opening/closing body in the closed state, and the term "width direction of the opening/closing body" refers to a direction that is substantially perpendicular to the opening/closing direction of the opening/closing body, but is not the thickness direction of the opening/closing body.
Further, the "opening/closing direction of the opening/closing body" refers to the sliding direction in which the opening/closing body closes or opens the space so as to partition it.

また、「開閉体幅方向外側」とは、開閉体幅方向に沿って開閉体の外側へ向かう方向側を意味する。例えば、向かって右側のガイドレールを基準にすると、開閉体幅方向外側は、右側のガイドレールの右方向側になる。
また、「開閉体幅方向内側」とは、開閉体幅方向に沿って開閉体の内側へ向かう方向側を意味する。例えば、向かって右側のガイドレールを基準にすると、開閉体幅方向内側は、右側のガイドレールの左方向側になる。 In addition, the term "outer side in the width direction of the opening/closing body" refers to the direction toward the outside of the opening/closing body along the width direction of the opening/closing body. For example, when the guide rail on the right side is used as a reference, the outer side in the width direction of the opening/closing body is the right side of the right guide rail.
In addition, the term "inner side in the width direction of the opening/closing body" refers to the direction toward the inside of the opening/closing body along the width direction of the opening/closing body. For example, when the guide rail on the right side is used as a reference, the inner side in the width direction of the opening/closing body is the left side of the right guide rail.

また、「開閉体厚さ方向内側」とは、開閉体厚さ方向に沿って開閉体の厚みの中央部へ向かう方向側を意味する。 Additionally, "outside in the thickness direction of the opening/closing body" refers to the side in the direction away from the center of the thickness of the opening/closing body along the thickness direction of the opening/closing body.
Additionally, the term "inner side in the thickness direction of the opening/closing body" refers to the side toward the center of the thickness of the opening/closing body along the thickness direction of the opening/closing body.

開閉装置１は、図１に示すように、空間を仕切るようにして閉鎖動作するとともに逆方向へ開放動作して巻き重ねられる開閉体１０と、開閉体１０を横幅方向の両側でそれぞれ開閉方向へ案内するガイドレール２０と、巻き重ねられた際の開閉体１０の間に挟まれる緩衝材３０と、開閉体１０をその開放方向側で巻き重ねて収納する収納部４０とを備え、例えば、ガレージや工場、窓サッシ等の開口部分に装着されるシャッター装置を構成している。 As shown in FIG. 1, the opening/closing device 1 comprises an opening/closing body 10 that divides a space and closes while opening in the opposite direction and is rolled up and stacked, guide rails 20 that guide the opening/closing body 10 in the opening/closing direction on both sides of the width direction, a cushioning material 30 that is sandwiched between the opening/closing body 10 when rolled up and stacked, and a storage section 40 that stores the opening/closing body 10 by rolling it up on the opening direction side, forming a shutter device that is attached to the opening part of a garage, factory, window sash, etc., for example.

開閉体１０は、横長略矩形状の金属板を曲げ加工してなるスラット１１ａを、上下に隣接するスラット１１ａ，１１ａ間で回動するように複数連接することで開閉体本体１１を構成し、この開閉体本体１１の閉鎖方向端部側に、全閉時の当接対象部位Ｇに当接させるための座板部材１２を横幅方向へわたって接続している（図１参照）。 The opening/closing body 10 is made by connecting multiple slats 11a, which are made by bending a horizontally elongated, roughly rectangular metal plate, so that the slats 11a, 11a adjacent to each other vertically, rotate between them to form the opening/closing body main body 11, and a seat plate member 12 is connected across the width to the closing end of the opening/closing body main body 11 for abutting against the contact target area G when the door is fully closed (see Figure 1).

各スラット１１ａは、開閉体幅方向へ連続するように延設された縦断面略凹状の部材であり、略板状（図示例によれば平板状）の本体片部１１ａ１と、本体片部１１ａ１の開放方向側で開閉体厚さ方向の一方（図３によれば左方向）へ突出した接続部１１ａ２と、本体片部１１ａ１の閉鎖方向側で前記一方へ突出して他のスラット１１ａの接続部１１ａ２に接続される被接続部１１ａ３と、対向する内面１１ａ４１，１１ａ４２間に緩衝材３０を嵌め合わせた嵌合凹部１１ａ４とを一体に有する。 Each slat 11a is a member with a generally concave vertical cross section that extends continuously in the width direction of the opening/closing body, and is integrally formed with a roughly plate-shaped (flat in the illustrated example) main body piece 11a1, a connecting portion 11a2 that protrudes to one side in the thickness direction of the opening/closing body (to the left in Figure 3) on the opening direction side of the main body piece 11a1, a connected portion 11a3 that protrudes to the one side on the closing direction side of the main body piece 11a1 and is connected to the connecting portion 11a2 of the other slat 11a, and a fitting recess 11a4 in which a cushioning material 30 is fitted between the opposing inner surfaces 11a41, 11a42.

開閉方向に隣り合う二つのスラット１１ａ，１１ａは、接続部１１ａ２と被接続部１１ａ３の係合によって、その一方が他方に対し回動可能であるとともに、その一方に対し他方を開閉体幅方向へスライドさせることが可能である。 Two slats 11a, 11a adjacent to each other in the opening and closing direction can rotate relative to one another by engaging the connecting portion 11a2 with the connected portion 11a3, and one can slide relative to the other in the width direction of the opening and closing body.

接続部１１ａ２は、例えば縦断面略フック状等、被接続部１１ａ３に掛止可能な適宜形状に曲げ形成される。
被接続部１１ａ３は、下方側から接続部１１ａ２を挿入して掛止可能なように、下方を開口した縦断面略カール状（別表現すれば、下方の開口した縦断面Ｃ字状）に形成される（図３参照）。 The connecting portion 11a2 is bent into an appropriate shape, such as a generally hook-shaped vertical cross section, so that it can be hooked onto the connected portion 11a3.
The connected portion 11a3 is formed with a generally curled cross section that opens downward (in other words, a C-shaped cross section that opens downward) so that the connecting portion 11a2 can be inserted from below and latched (see FIG. 3).

また、被接続部１１ａ３は、本体片部１１ａ１の下端側から開閉体厚さ方向の一方へ突出しており、その突端部を、当接部１１ａ３１として機能させる。この当接部１１ａ３１は、開閉体１０が巻き重ねられて、緩衝材３０が開閉体１０の内面と外面に挟まれて弾性変形した後に、開閉体１０の外面に対し直接当接する（図５及び図６参照）。 The connected portion 11a3 protrudes from the lower end side of the main body piece 11a1 in one direction in the thickness direction of the opening/closing body, and its tip functions as the abutment portion 11a31. This abutment portion 11a31 directly abuts against the outer surface of the opening/closing body 10 after the opening/closing body 10 is wound and overlapped, and the cushioning material 30 is sandwiched between the inner and outer surfaces of the opening/closing body 10 and elastically deformed (see Figures 5 and 6).

嵌合凹部１１ａ４は、開閉体厚さ方向の一方側の内面１１ａ４１と該内面に対向して間隔を置いた他方側の内面１１ａ４２とを有し、これら内面間の下方を底部とした縦断面有底筒状に形成される。 The fitting recess 11a4 has an inner surface 11a41 on one side in the thickness direction of the opening/closing body and an inner surface 11a42 on the other side facing and spaced from the inner surface, and is formed into a cylindrical shape with a bottom in vertical cross section with the bottom being below the space between these inner surfaces.

一方側の内面１１ａ４１は、本体片部１１ａ１の一部分である。すなわち、この内面１１ａ４１は、本体片部１１ａ１により形成される。
また、他方側の内面１１ａ４２は、被接続部１１ａ３の一部分である。すなわち、この内面１１ａ４２は、被接続部１１ａ３により形成される。 The inner surface 11a41 on one side is a part of the main body piece 11a1. In other words, the inner surface 11a41 is formed by the main body piece 11a1.
The inner surface 11a42 on the other side is a part of the connected portion 11a3. In other words, the inner surface 11a42 is formed by the connected portion 11a3.

嵌合凹部１１ａ４の内部は、下方へ行くにしたがって開閉体厚さ方向の幅が徐々に広くなっている（図３参照）。
この嵌合凹部１１ａ４には、開閉体１０が巻重ねられた際の内面と外面の間に位置するように緩衝材３０が装着される。 The inside of the fitting recess 11a4 has a width gradually increasing in the thickness direction of the opening/closing body toward the bottom (see FIG. 3).
A cushioning material 30 is attached to this fitting recess 11a4 so as to be positioned between the inner and outer surfaces of the opening/closing body 10 when it is rolled up.

緩衝材３０は、ガイドレール２０よりも開閉体幅方向内側において、開閉体１０の各スラット１１ａにおける横幅方向の中央寄りに部分的に配設される（図１及び図２参照）。
この緩衝材３０は、上下の接続部１１ａ２と被接続部１１ａ３の間で弾性変形するように配設され、そして、緩衝材３０は、開閉体厚さ方向において、接続部１１ａ２及び被接続部１１ａ３よりも反本体片部１１ａ１側へ突出している（図３参照）。 The buffer material 30 is partially disposed on the inner side of the guide rail 20 in the opening/closing body width direction, and toward the center in the lateral width direction of each slat 11a of the opening/closing body 10 (see Figs. 1 and 2).
This cushioning material 30 is arranged so as to be elastically deformable between the upper and lower connecting portions 11a2 and the connected portions 11a3, and the cushioning material 30 protrudes toward the opposite main body piece 11a1 side in the thickness direction of the opening/closing body beyond the connecting portion 11a2 and the connected portion 11a3 (see Figure 3).

この緩衝材３０は、嵌合凹部１１ａ４に嵌り合って固定される被固定部３１と、この被固定部３１から反本体片部１１ａ１側（図３によれば左側）へ突出して巻き重ねられた際の開閉体１０の間に挟まれて弾性変形する変形部３２とを一体的に具備し、被固定部３１を変形部３２よりも硬質な材料により形成し、変形部３２を合成樹脂材料により形成している。 This cushioning material 30 is integrally provided with a fixed portion 31 that fits into and is fixed to the fitting recess 11a4, and a deforming portion 32 that protrudes from the fixed portion 31 toward the opposite side of the main body piece 11a1 (the left side in FIG. 3) and is sandwiched between the opening/closing body 10 when it is rolled up and overlapped, and the fixed portion 31 is made of a harder material than the deforming portion 32, and the deforming portion 32 is made of a synthetic resin material.

これら被固定部３１と変形部３２を接続する手段は、例えば、変形部３２の成形時に被固定部３１を一体化する態様や、被固定部３１に対し変形部３２を嵌合固定した態様、被固定部３１に対し変形部３２を接着した態様、被固定部３１に対し変形部３２をネジやリベット等により止着した態様等とすればよい。 The means for connecting the fixed portion 31 and the deforming portion 32 may be, for example, a mode in which the fixed portion 31 is integrated when the deforming portion 32 is molded, a mode in which the deforming portion 32 is fitted and fixed to the fixed portion 31, a mode in which the deforming portion 32 is glued to the fixed portion 31, or a mode in which the deforming portion 32 is attached to the fixed portion 31 with screws, rivets, etc.

被固定部３１は、略帯状の金属板をプレス加工や曲げ加工等することで、嵌合凹部１１ａ４に嵌り合う曲げ形状に形成される。
詳細に説明すれば、この被固定部３１は、スラット１１ａの本体片部１１ａ１に沿って下方へ延設された平板部３１ａと、この平板部３１ａの下端側を曲げて当接部１１ａ３１へ向かって斜め上方へ延設してなる傾斜片部３１ｂ（第二の突片部）とを有し、縦断面略Ｖ字状に形成される（図３参照）。
この被固定部３１は、平板部３１ａと傾斜片部３１ｂの間を拡げようとする弾性的な復元力を保持している。 The fixed portion 31 is formed by pressing or bending a substantially strip-shaped metal plate into a bent shape that fits into the fitting recess 11a4.
In more detail, the fixed portion 31 has a flat portion 31a extending downward along the main body piece 11a1 of the slat 11a, and an inclined piece portion 31b (second protruding piece portion) formed by bending the lower end side of the flat portion 31a and extending diagonally upward toward the abutment portion 11a31, and is formed in an approximately V-shape in vertical cross section (see Figure 3).
The fixed portion 31 has an elastic restoring force tending to widen the gap between the flat portion 31a and the inclined piece portion 31b.

この被固定部３１の材質は、弾性的に撓み変形可能であって且つ耐食性の高い金属材料が好ましく、例えばステンレス製の板材（ばね用ステンレス鋼帯）等とする。 The material of the fixed part 31 is preferably a metal material that is elastically deformable and highly corrosion-resistant, such as a stainless steel plate (stainless steel strip for springs).

平板部３１ａには、その中央側部分に凹状の切り込みを入れてその内側を本体片部１１ａ１側へ曲げてなる第一の突片部３１ａ１が設けられる。この第一の突片部３１ａ１は、本体片部１１ａ１へ向かう斜め上方へ延設され、その突端のエッジ状部分（対向部分）を、嵌合凹部１１ａ４における一方側の内面１１ａ４１（本体片部１１ａ１）に圧接する。 The flat plate portion 31a has a first protrusion 31a1 formed by cutting a concave portion in the center and bending the inside toward the main body piece 11a1. The first protrusion 31a1 extends obliquely upward toward the main body piece 11a1, and the edge-like portion (facing portion) of its tip is pressed against the inner surface 11a41 (main body piece 11a1) on one side of the mating recess 11a4.

傾斜片部３１ｂは、当接部１１ａ３１へ向かって斜め上方へ突出する第二の突片部である。この傾斜片部３１ｂ（第二の突片部）は、その突端のエッジ状部分を、嵌合凹部１１ａ４における他方の内面１１ａ４２（被接続部１１ａ３）に圧接する。内面１１ａ４２は、本体片部１１ａ１へ向かって斜め上方へ傾斜しており、この傾斜面により前記エッジ状部分を受ける（図３参照）。 The inclined piece 31b is a second protruding piece that protrudes obliquely upward toward the abutting portion 11a31. This inclined piece 31b (second protruding piece) presses the edge-shaped portion of its tip against the other inner surface 11a42 (connected portion 11a3) of the mating recess 11a4. The inner surface 11a42 is inclined obliquely upward toward the main body piece 11a1, and this inclined surface receives the edge-shaped portion (see FIG. 3).

変形部３２は、弾性を有する合成樹脂材料により形成され、開閉体１０が巻き重ねられた際に、スラット１１ａの本体片部１１ａ１に当接して弾性変形する。
すなわち、この変形部３２は、開閉体１０が巻き重ねられていない状態では、少なくともその一部が、被接続部１１ａ３及び接続部１１ａ２よりも開閉体厚さ方向の一方（図示例によれば反本体片部１１ａ１側）へ突出している。
変形部３２は、弾性的に撓むことが可能であって且つ弾性的に圧縮変形可能な材料から形成され本実施の形態の好ましい一例によれば、ポリ塩化ビニルを用いている。他例としては、ゴムや他のエラストマー樹脂等の弾性樹脂材料とすることが可能である。 The deformation portion 32 is made of an elastic synthetic resin material, and when the opening/closing body 10 is rolled up and stacked, it comes into contact with the main body piece portion 11a1 of the slat 11a and elastically deforms.
In other words, when the opening/closing body 10 is not wound, at least a portion of this deformation portion 32 protrudes to one side in the thickness direction of the opening/closing body (to the side opposite the main body piece portion 11a1 in the illustrated example) beyond the connected portion 11a3 and the connecting portion 11a2.
The deformation portion 32 is made of a material that can be elastically bent and elastically compressively deformed, and in one preferred embodiment of the present invention, polyvinyl chloride is used. As another example, the deformation portion 32 may be made of an elastic resin material such as rubber or other elastomer resin.

図示例の変形部３２は、本体片部１１ａ１側から被接続部１１ａ３側へ向かうように、開閉体厚さ方向へ突出し、その突端側を開閉体開閉方向へ延設した形状である（図３参照）。
詳細に説明すれば、この変形部３２は、被接続部１１ａ３の上面に接触又は近接する突出片部３２ａと、この突出片部３２ａの突端側で曲げられて被接続部１１ａ３から離れる方向（図示例によれば上方）へ延設された凸曲面状（図示例によれば縦断面略円弧状）の当接片部３２ｂと、突出片部３２ａの基端側で曲げられて上方へ延設された平板状の基片部３２ｃとを一体に有する。 The deformation portion 32 in the illustrated example protrudes in the thickness direction of the opening/closing body from the main body piece 11a1 side toward the connected portion 11a3 side, and has its tip side extending in the opening/closing direction of the opening/closing body (see FIG. 3).
In more detail, this deformation portion 32 has, integrally, a protruding piece portion 32a that is in contact with or close to the upper surface of the connected portion 11a3, a contact piece portion 32b that is convexly curved (in the illustrated example, the longitudinal section is approximately arc-shaped) that is bent at the tip side of the protruding piece portion 32a and extended in a direction away from the connected portion 11a3 (upward in the illustrated example), and a flat base piece portion 32c that is bent at the base end side of the protruding piece portion 32a and extended upward.

この変形部３２は、変形部３２を本体片部１１ａ１側へ撓ませるように形成され、その撓み方向側における突出片部３２ａの内面に、開閉体幅方向へ延設された凹溝３２ａ１を有する。この凹溝３２ａ１は、図示例によれば縦断面略半円状に形成され、開閉体厚さ方向に適宜間隔を置いて複数設けられる（図３参照）。 The deformation portion 32 is formed so as to deflect the deformation portion 32 toward the main body piece 11a1, and has a groove 32a1 extending in the width direction of the opening/closing body on the inner surface of the protruding piece 32a on the deflection direction side. In the illustrated example, the groove 32a1 is formed in a substantially semicircular vertical cross section, and multiple grooves 32a1 are provided at appropriate intervals in the thickness direction of the opening/closing body (see FIG. 3).

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。このガイドレール２０内には、必要に応じて、多光軸センサ等の障害物感知センサが設けられる。 The guide rails 20 are provided on both the left and right sides of the opening/closing body 10 .
Each guide rail 20 is inserted into the opening at the end side in the width direction of the opening/closing body 10 so as to surround the opening in a concave cross section, and continues in the vertical direction between the contact target site G and the storage section 40. An obstacle detection sensor such as a multi-axis sensor is provided inside the guide rail 20 as necessary.

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。 As shown in FIG. 1, the storage section 40 includes a storage case 41 with an opening formed at the bottom for the opening/closing body 10 to appear and disappear, a winding shaft 42 for winding and unwinding the opening/closing body 10, an opening/closing machine 43 for driving and rotating the winding 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５及び図６参照）、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 winding shaft 42 is formed in a cylindrical shape with its axial direction facing the width direction of the opening/closing body, and the upper end of the opening/closing body 10 is connected to its outer circumferential surface. When the winding shaft 42 rotates in one direction, it winds up the opening/closing body 10 on its outer circumferential surface (see Figures 5 and 6), and when it rotates in the opposite direction, it unrolls the opening/closing body 10 downward.

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。
開閉体１０が巻取軸４２に巻き取られると、図５に示すように、先ず径方向の最も内側になるスラット１１ａの内面が、巻取軸４２の外周面に当接する。
詳細に説明すれば、各スラット１１ａの緩衝材３０が巻取軸４２の外周面に当接して弾性的に徐々に撓んだ後、被接続部１１ａ３の当接部１１ａ３１が巻取軸４２の外周面に当接する。 Next, the characteristic functions and effects of the opening and closing device 1 having the above configuration will be described in detail.
When the opening/closing body 10 is wound around the winding shaft 42, the inner surface of the radially innermost slat 11a first comes into contact with the outer circumferential surface of the winding shaft 42, as shown in FIG.
More specifically, the cushioning material 30 of each slat 11a abuts against the outer circumferential surface of the winding shaft 42 and gradually bends elastically, and then the abutting portion 11a31 of the connected portion 11a3 abuts against the outer circumferential surface of the winding shaft 42.

次に、内側の開閉体１０に対し、その外側の開閉体１０が巻き重ねられる際は、先ず外側のスラット１１ａの緩衝材３０が、内側のスラット１１ａの外面に当接する（図５参照）。この時点では、被接続部１１ａ３の当接部１１ａ３１と内側のスラット１１ａの間には隙間Ｓを有する。
この後、緩衝材３０が弾性的に徐々に撓む。この際、緩衝材３０は、各凹溝３２ａ１の溝幅を徐々に狭めるようにして柔軟に撓む。そして、このような撓み変形の後、被接続部１１ａ３の当接部１１ａ３１が内側のスラット１１ａの外面に当接する。
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。 Next, when the outer opening/closing body 10 is wrapped around the inner opening/closing body 10, the cushioning material 30 of the outer slat 11a first abuts against the outer surface of the inner slat 11a (see FIG. 5). At this point, there is a gap S between the abutting portion 11a31 of the connected portion 11a3 and the inner slat 11a.
After this, the cushioning material 30 gradually bends elastically. At this time, the cushioning material 30 flexes flexibly so as to gradually narrow the groove width of each recessed groove 32a1. After such bending deformation, the abutting portion 11a31 of the connected portion 11a3 abuts against the outer surface of the inner slat 11a.
Furthermore, when the opening/closing body 10 is unwound from the winding shaft 42 to perform the closing operation, each of the cushioning materials 30 elastically returns to its original state.

前記したように、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が当接して徐々に弾性的に撓み、この後で、被接続部１１ａ３の当接部１１ａ３１が巻取軸４２外周面又は内側のスラット１１ａ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 contacts the outer periphery of the inner winding shaft 42 or the surface of the slat 11a, the cushioning material 30 first comes into contact and gradually bends elastically, and then the contact portion 11a31 of the connected portion 11a3 slowly comes into contact with the outer periphery of the winding shaft 42 or the inner slat 11a. This gradual contact can therefore reduce noise, vibration, and other impacts.

しかも、各緩衝材３０が接続部１１ａ２と被接続部１１ａ３の間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。 In addition, each cushioning material 30 flexes and deforms to fit between the connecting portion 11a2 and the connected portion 11a3, which helps prevent the winding diameter of the opening/closing body 10 from increasing.

また、軟質の緩衝材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、硬質の被接続部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、傷や、緩衝材３０によるゴム跡、摩耗粉等が付いたりする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。 In addition, the pressure applied by the soft cushioning material 30 to the inner member (the winding shaft 42 or the slat 11a) is kept at a substantially constant low pressure after the hard connected portion 11a3 comes into contact with the inner member, which reduces the occurrence of scratches, rubber marks, wear powder, etc. caused by the cushioning material 30 on the outer surface of each slat 11a.
Therefore, there is no need to arrange the cushioning material 30 so that it is hidden within the guide rail 20, and it is exposed toward the center of the width of the opening/closing body 10, which has the greatest deflection in the width direction, thereby effectively reducing the winding noise, etc., of the opening/closing body 10.

特に上記実施態様では、緩衝材３０の内側に複数の凹溝３２ａ１を設けているため、緩衝材３０の変形可動域を比較的大きく確保することができる上、冬期等の低温時においても、変形部３２の弾力的な撓み特性を保持して、振動及び騒音を効果的に軽減することができる。
すなわち、本願発明者等は、緩衝材３０から凹溝３２ａ１を省いた場合、低温時に変形部３２の弾力性が失われて、変形した後の変形部３２が元の状態に復元し難くなるが、凹溝３２ａ１を有する緩衝材３０にでは、このようなことを低減することができる。 In particular, in the above embodiment, multiple grooves 32a1 are provided on the inside of the cushioning material 30, so that a relatively large deformation range of the cushioning material 30 can be ensured, and even at low temperatures such as in winter, the elastic bending characteristics of the deforming portion 32 can be maintained, thereby effectively reducing vibration and noise.
In other words, the inventors of the present application have found that if the groove 32a1 is omitted from the cushioning material 30, the elasticity of the deformed portion 32 is lost at low temperatures, making it difficult for the deformed portion 32 to return to its original state after deformation; however, with the cushioning material 30 having the groove 32a1, this can be reduced.

また、金属製の被固定部３１における第一の突片部３１ａ１及び傾斜片部３１ｂ（第二の突片部）が、弾性復元力により、嵌合凹部１１ａ４の内面１１ａ４１，１１ａ４２に圧接されるため、緩衝材３０が安易に外れてしまうようなことを防ぐことができる。 In addition, the first protrusion 31a1 and the inclined piece 31b (second protrusion) of the metal fixed part 31 are pressed against the inner surfaces 11a41 and 11a42 of the fitting recess 11a4 by the elastic restoring force, which prevents the cushioning material 30 from easily coming off.

また、上記実施態様によれば、緩衝材３０が被接続部１１ａ３に接触又は近接するため、緩衝材３０の撓み変形の方向を安定させることができる。 In addition, according to the above embodiment, the cushioning material 30 is in contact with or close to the connected portion 11a3, so the direction of the bending deformation of the cushioning material 30 can be stabilized.

なお、上記実施態様によれば、特に好ましい一例として、変形部３２を上方へ延設したが、この変形部３２の他例としては、下方へ延設した態様とすることも可能である。 In the above embodiment, the deformation portion 32 is extended upward as a particularly preferred example, but another example of the deformation portion 32 is that it can be extended downward.

＜変形例＞
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、重複する詳細説明は省略する。 <Modification>
Next, a modification of the above configuration will be described.
The following modified examples are obtained by partially changing the configuration of the opening and closing device 1 described above, and therefore mainly the changed parts will be described in detail, and overlapping detailed descriptions will be omitted.

図７に示す緩衝材３０’は、上記緩衝材３０について、突出片部３２ａから凹溝３２ａ１を省いたものである。
この緩衝材３０’を用いた開閉装置も、上記開閉装置１と略同様に、振動及び騒音を低減する効果や、開閉体１０面の傷防止効果等を有する。ただし、低温時の効果については、上記緩衝材３０を用いた開閉装置１の方が優れている。 A cushioning material 30' shown in FIG. 7 is similar to the cushioning material 30 described above except that the recessed groove 32a1 is omitted from the protruding piece 32a.
The opening and closing device using this cushioning material 30' has the effect of reducing vibration and noise and preventing scratches on the surface of the opening and closing body 10, similar to the opening and closing device 1. However, the opening and closing device 1 using the cushioning material 30 is superior in terms of effectiveness at low temperatures.

図８及び図９に示す緩衝材５０は、緩衝材３０のものと同様の被固定部３１と、この被固定部３１から反本体片部１１ａ１側（図９によれば左側）へ突出して巻き重ねられた際の開閉体１０の間に挟まれて弾性変形する変形部５２とを一体的に具備し、被固定部３１を金属材料により形成し、変形部５２を合成樹脂材料により形成している。被固定部３１と変形部５２を接続する手段は、上記緩衝材３０と同様である。 The cushioning material 50 shown in Figures 8 and 9 is integrally equipped with a fixed portion 31 similar to that of the cushioning material 30, and a deforming portion 52 that protrudes from the fixed portion 31 toward the opposite side of the main body piece 11a1 (the left side in Figure 9) and is sandwiched between the opening and closing body 10 when it is wound and overlapped, and is elastically deformed. The fixed portion 31 is made of a metal material, and the deforming portion 52 is made of a synthetic resin material. The means for connecting the fixed portion 31 and the deforming portion 52 is the same as that of the cushioning material 30 described above.

変形部５２は、上記変形部３２と同様の合成樹脂材料により形成され、開閉体１０が巻き重ねられた際に、スラット１１ａの本体片部１１ａ１に当接して弾性変形する。
この変形部５２は、被固定部３１の上端に接続されスラット１１ａに沿って上方へ延設された基片部５２ａと、この基片部５２ａから反本体片部１１ａ１側へ突出した突出片部５２ｂと、突出片部５２ｂの突端側に接続された中空状の当接部５２ｃとを一体に有する。 The deformation portion 52 is made of the same synthetic resin material as the deformation portion 32, and when the opening-closing body 10 is wound and overlapped, it abuts against the main body piece portion 11a1 of the slat 11a and elastically deforms.
This deformation portion 52 integrally has a base piece portion 52a connected to the upper end of the fixed portion 31 and extending upward along the slat 11a, a protruding piece portion 52b protruding from this base piece portion 52a toward the opposite main body piece portion 11a1, and a hollow abutment portion 52c connected to the tip side of the protruding piece portion 52b.

突出片部５２ｂは、当接部５２ｃ及び基片部５２ａよりも開閉体厚さ方向の厚みが薄く、開閉体幅方向に所定幅を有する板状に形成され、基片部５２ａから当接部５２ｃへ向かって斜め上方へ延設され、基片部５２ａと当接部５２ｃの間を縦断面括れ状に形成している（図９参照）。この括れ状部分（突出片部５２ｂ）は、当接部５２ｃを柔軟に首振り運動させる。
この突出片部５２ｂの基端側には、その撓み方向側（図示例によれば上側）の面に、開閉体幅方向へわたる凹溝５２ｂ１が形成される。 The protruding piece 52b is thinner in the thickness direction of the opening/closing body than the abutment part 52c and the base piece 52a, is formed in a plate shape having a predetermined width in the width direction of the opening/closing body, extends obliquely upward from the base piece 52a toward the abutment part 52c, and forms a constricted shape in vertical cross section between the base piece 52a and the abutment part 52c (see FIG. 9). This constricted part (protruding piece 52b) allows the abutment part 52c to flexibly swing.
A recessed groove 52b1 is formed in the base end of the protruding piece 52b on the surface in the bending direction (the upper side in the illustrated example) so as to extend in the width direction of the opening/closing body.

当接部５２ｃは、突端側を凸曲面状（図示例によれば縦断面略円弧状）に形成した中空状の部位であり、開閉体幅方向へ筒状に延設される（図８参照）。
この当接部５２ｃを構成する周壁には、該周壁の撓み方向側となる内面に、開閉体幅方向へわたる凹溝５２ｃ１が設けられる。 The contact portion 52c is a hollow portion whose tip end is formed into a convex curved surface (approximately arc-shaped in vertical section in the illustrated example) and extends cylindrically in the width direction of the opening/closing body (see FIG. 8).
The peripheral wall constituting this abutting portion 52c is provided with a recessed groove 52c1 extending in the width direction of the opening/closing body on the inner surface on the bending direction side of the peripheral wall.

上記構成の緩衝材５０は、上記緩衝材３０と同様に、ガイドレール２０よりも開閉体幅方向内側において、開閉体１０の各スラット１１ａにおける横幅方向の中央寄りに部分的に配設される（図８参照）。 The cushioning material 50 of the above configuration, like the cushioning material 30, is partially arranged on the inside of the guide rail 20 in the opening/closing body width direction, toward the center of the width direction of each slat 11a of the opening/closing body 10 (see Figure 8).

よって、上記構成の緩衝材５０を開閉体１０に装着した開閉装置によれば、開閉体１０が開放動作により巻き重ねられる際に、緩衝材５０の突端側の当接部５２ｃが、巻取軸４２又は内側のスラット１１ａに当接する。
この当接の際、中空状の当接部５２ｃが周壁を凹ませるようにして弾性変形するとともに、突出片部５２ｂが上方へ撓む。また、当接部５２ｃは、本体片部１１ａ１との当接により、突出片部５２ｂ側を基点とした首振り運動をする。
そして、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上、スラット１１ａ面に傷やゴム跡、摩耗粉等が付くのを防ぐことができる。
また、開閉体１０が閉鎖動作により巻取軸４２から繰り出される際は、緩衝材５０が元の形状に弾性的に復元する。
緩衝材５０の弾力的な撓み特性は、凹溝５２ｂ１，５２ｃ１等の構成により、低温時にも十分に保持される。 Therefore, in an opening/closing device in which the cushioning material 50 of the above configuration is attached to the opening/closing body 10, when the opening/closing body 10 is rolled up by the opening operation, the abutment portion 52c on the tip side of the cushioning material 50 abuts against the winding shaft 42 or the inner slat 11a.
At the time of this contact, the hollow contact portion 52c elastically deforms so as to dent the peripheral wall, and the protruding piece 52b bends upward. In addition, the contact portion 52c makes a swinging motion with the protruding piece 52b side as a base point due to the contact with the main body piece 11a1.
Then, after this, the contact portion 11a31 of the connected portion 11a3 slowly comes into contact with the surface of the slat 11a. This gradual contact not only reduces the impact of noise and vibration, but also prevents scratches, rubber marks, wear powder, and the like from being left on the surface of the slat 11a.
Furthermore, when the opening/closing body 10 is unwound from the winding shaft 42 by the closing operation, the cushioning material 50 elastically returns to its original shape.
The elastic bending characteristics of the buffer material 50 are sufficiently maintained even at low temperatures due to the configuration of the recessed grooves 52b1, 52c1, etc.

このように、緩衝材３０を緩衝材５０に置換した開閉装置においても、緩衝材３０を具備した上記開閉装置１と略同等又は同等以上の作用効果を得ることができる。 In this way, even in an opening and closing device in which the cushioning material 30 is replaced with the cushioning material 50, it is possible to obtain effects that are approximately the same as or greater than those of the opening and closing device 1 equipped with the cushioning material 30.

なお、上記実施態様によれば、被固定部３１を金属材料から形成したが、被固定部３１の他例としては、硬質合成樹脂材料等、変形部３２よりも硬質な材料により形成することが可能である。 In the above embodiment, the fixed portion 31 is made of a metal material, but as another example, the fixed portion 31 can be made of a material that is harder than the deformable portion 32, such as a hard synthetic resin material.

また、上記実施態様によれば、スラット１１ａにおける本体片部１１ａ１と被接続部１１ａ３の間に嵌合凹部１１ａ４を形成したが、他例としては、本体片部１１ａ１と接続部１１ａ２の間に略同様の嵌合凹部（図示せず）を形成し、この嵌合凹部に緩衝材を嵌合固定することも可能である。 In addition, according to the above embodiment, a mating recess 11a4 is formed between the main body piece 11a1 and the connected part 11a3 of the slat 11a, but as another example, it is also possible to form a substantially similar mating recess (not shown) between the main body piece 11a1 and the connecting part 11a2, and to fit and fix a cushioning material into this mating recess.

また、上記実施態様によれば、特に好ましい態様として、上記変形部を主に撓み変形するように構成したが、他例としては、上記変形部を、ほとんど撓むことなく弾性的に圧縮変形する構成とすることも可能である。 In addition, according to the above embodiment, as a particularly preferred embodiment, the deformation portion is configured to mainly undergo bending deformation, but as another example, it is also possible to configure the deformation portion to undergo elastic compressive deformation with almost no bending.

また、上記実施態様によれば、前記緩衝材を各スラット１１ａの幅方向中央側に単数設けたが、他例としては、前記緩衝材を各スラット１１ａの幅方向に間隔を置いて複数設けた態様や、前記緩衝材を各スラット１１ａの略全長にわたる長尺状に設けた態様等とすることも可能である。 In addition, in the above embodiment, a single cushioning material is provided at the center of the width of each slat 11a, but as other examples, it is also possible to provide multiple cushioning materials at intervals in the width direction of each slat 11a, or to provide the cushioning material in a long shape that spans approximately the entire length of each slat 11a.

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。
また、上記緩衝材を接続部１１ａ２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、接続部１１ａ２よりも開閉体厚さ方向の一方へ突出させ、同変形部の一部を被接続部１１ａ３よりも突出しないようにすることが可能である。 Furthermore, according to the above embodiment, when the opening/closing body 10 is not wound, a part of the deformed portion protrudes in one direction in the thickness direction of the opening/closing body beyond the connected portion 11a3 and the connecting portion 11a2. However, as another example, it is also possible to configure the deformed portion to protrude in one direction in the thickness direction of the opening/closing body beyond the connected portion 11a3 or the connecting portion 11a2.
In other words, when the cushioning material is provided closer to the connected portion 11a3, when the opening/closing body 10 is not wound, it is possible to make a portion of the deformed portion protrude in one direction in the thickness direction of the opening/closing body beyond the connected portion 11a3, and to make a portion of the deformed portion not protrude beyond the connecting portion 11a2.
Furthermore, when the cushioning material is provided closer to the connection portion 11a2, when the opening/closing body 10 is not wound, it is possible to make a portion of the deformed portion protrude in one direction in the thickness direction of the opening/closing body beyond the connection portion 11a2, and to prevent a portion of the deformed portion from protruding beyond the connected portion 11a3.

また、上記実施態様における緩衝材では、単数の上記被固定部に対し単数の上記変形部を接続したが、上記緩衝材の他例としては、上記被固定部と上記変形部のいずれか一方又は双方を、開閉体幅方向に複数設けた態様とすることも可能である。
すなわち、単数の上記被固定部に対し、開閉体幅方向に並ぶ複数の上記変形部を接続した態様や、開閉体幅方向に並ぶ複数の上記被固定部に対し、単数の上記変形部を接続した態様、開閉体幅方向に並ぶ複数の上記被固定部に対し、開閉体幅方向に並ぶ複数の上記変形部を接続した態様等とすることが可能である。
また、上記緩衝材は、単数又は複数の上記被固定部よりも、単数又は複数の上記変形部を開閉体幅方向へ長く設けた態様や、単数又は複数の上記被固定部よりも、単数又は複数の上記変形部を開閉体幅方向へ短く設けた態様等とすることが可能である。 In addition, in the cushioning material in the above embodiment, a single deforming portion is connected to a single fixed portion, but in another example of the cushioning material, it is also possible to have a configuration in which either one or both of the fixed portion and the deforming portion are provided in multiple locations in the width direction of the opening/closing body.
In other words, it is possible to connect a single fixed portion to multiple deformable portions arranged in the width direction of the opening/closing body, connect a single deformable portion to multiple fixed portions arranged in the width direction of the opening/closing body, or connect multiple deformable portions arranged in the width direction of the opening/closing body to multiple fixed portions arranged in the width direction of the opening/closing body.
In addition, the cushioning material can be configured in such a way that the single or multiple deformable portions are longer in the width direction of the opening/closing body than the single or multiple fixed portions, or that the single or multiple deformable portions are shorter in the width direction of the opening/closing body than the single or multiple fixed portions.

また、上記実施態様によれば、上記緩衝材を所定の複数のスラット１１ａにそれぞれ設けたが、他例としては、上記緩衝材を所定数置きのスラット１１ａに設けた態様や、全数のスラット１１ａに設けた態様、図示例以外の任意のスラット１１ａに設けた態様等とすることが可能である。 In addition, in the above embodiment, the cushioning material is provided on each of a predetermined number of slats 11a, but other examples include providing the cushioning material on every predetermined number of slats 11a, providing the cushioning material on all slats 11a, providing the cushioning material on any slat 11a other than the illustrated example, etc.

また、上記実施態様は、単数の巻取軸４２を備える一軸式の開閉装置１に対し、本発明を適用したが、本発明は、開閉体１０を第一の軸体により開閉方向に対する交差方向へ導いた後に第二の軸体（巻取軸）に巻き取るようにした二軸式の開閉装置等、複数軸式の開閉装置に適用することも可能である。 In the above embodiment, the present invention is applied to a single-shaft opening and closing device 1 equipped with a single winding shaft 42, but the present invention can also be applied to a multi-shaft opening and closing device, such as a two-shaft opening and closing device in which the opening and closing body 10 is guided by a first shaft in a direction intersecting the opening and closing direction and then wound up on a second shaft (winding shaft).

また、本発明は上述した実施態様に限定されず、本発明の要旨を変更しない範囲で適宜変更可能である。 Furthermore, the present invention is not limited to the above-mentioned embodiments, and can be modified as appropriate without departing from the spirit and scope of the present invention.
