There is a building shutter that is received from below by a support member (a pair of rollers 28, 28).
この従来技術によれば、卷取体 (卷取部 4)を下方力 受ける構造としているため、 卷取体をその両端部のみで支持する構造と比較し、卷取体 (卷取部 4)の軸方向中 央側が下方へ橈んでしまうのを抑制することができ、特に、卷取体 (卷取部 4)の軸方 向寸法が比較的長い場合等に効果的である。  According to this conventional technology, the torsion body (accepting part 4) receives a downward force, so that the torsion body (tolerance part 4) is compared with a structure in which the torsion body is supported only at both ends thereof. It is possible to prevent the center in the axial direction from being squeezed downward, which is particularly effective when the axial dimension of the scraper (trapping section 4) is relatively long.
[0003] し力しながら、上記従来技術では、製造バラツキ等に起因して、卷取体の中心線と 支持部材の中心線とが平行でない場合には、卷取体に巻かれた開閉体の外周面と 、支持部材との面圧(単位面積あたりの荷重)が、開閉体幅方向において均一になら ないことがある。  [0003] However, in the above prior art, due to manufacturing variations and the like, if the center line of the trimming body and the center line of the support member are not parallel, the opening / closing body wound around the trimming body In some cases, the surface pressure (load per unit area) between the outer peripheral surface and the support member is not uniform in the opening / closing body width direction.
更に、特許文献 1のように支持部材を一対のローラにより構成している場合には、こ れらローラの回転中心間の距離の 1 Z2となる中心の真上に卷取体の回転中心が一 致しないと、何れか一方のローラに荷重が偏ってしまうことになる。  Further, when the support member is constituted by a pair of rollers as in Patent Document 1, the rotation center of the scraper is located directly above the center at which the distance between the rotation centers of these rollers is 1 Z2. If they do not match, the load will be biased to one of the rollers.
また、卷取体をその軸方向へ並ぶ複数の支持部材によって受けるようにした場合に は、複数の支持部材の高さのバラツキ等に起因して、卷取体に巻かれた開閉体の外 周面と上記支持部材との面圧力 支持部材毎に異なってしまうことがある。  In addition, when the scooping body is received by a plurality of support members arranged in the axial direction, the outside of the opening / closing body wound around the scooping body is caused by the height variation of the plurality of supporting members. The surface pressure between the peripheral surface and the support member may be different for each support member.
そして、前記のような面圧のバラツキや荷重の偏り等を生じた場合、卷取体の外周 面と支持部材との間に挟まれた開閉体が、局部的に強く押圧されて磨耗してしまった り、支持部材の耐久性が低下してしまったり等するおそれがある。 [0004] また、特許文献 1に記載された従来技術では、開閉体 (耐火性シート 6)に、避難等 のための通過口および該通過口を開閉する可撓性シート材の扉部を設けるようにし た場合には、卷取体 (卷取部 4)に開閉体 (耐火性シート 6)を巻き取った際に、その 巻き取られた開閉体 (耐火性シート 6)が前記扉部の箇所で卷太りしてしまうため、そ の卷太り箇所が一対のローラ (28, 28)に接触することで、開閉体 (耐火性シート 6) が各ローラ(28)から強 、押圧力を受けて損傷したり、各ローラ(28)の耐久性が低下 してしまったり等するおそれがある。 When the above-described surface pressure variation or load imbalance occurs, the opening / closing body sandwiched between the outer peripheral surface of the scraper and the support member is locally pressed and worn. There is a risk that the support member may be damaged or the durability of the support member may be reduced. [0004] In the prior art described in Patent Document 1, the opening / closing body (fireproof sheet 6) is provided with a passage for evacuation and the like, and a flexible sheet material door for opening and closing the passage. In this case, when the opening / closing body (fireproof sheet 6) is wound around the scraper body (trapping section 4), the wound opening / closing body (fireproof sheet 6) is Since the thickened part comes into contact with the pair of rollers (28, 28), the opening / closing body (fireproof sheet 6) receives strong pressure from each roller (28). Damage, or the durability of each roller (28) may be reduced.

The parts include a roller-like aspect that rotates by receiving the winding body and the opening / closing body wound around the winding body, and the opening / closing body wound around the winding body and the winding body. It includes a mode in which it is received from below and slid and rotated.
[0011] また、上記弾性シートとは、厚さ方向に弾性を有するシート状の部材であればよぐ この弾性シートの材料の具体例としては、ゴムや、弾性合成樹脂材料、発泡材料、あ るいはこれらの複合材等が挙げられる。  [0011] The elastic sheet may be a sheet-like member having elasticity in the thickness direction. Specific examples of the material of the elastic sheet include rubber, elastic synthetic resin material, foam material, Or these composite materials etc. are mentioned.
この弾性シートは、上記卷取体と支持部材との間に単数設けられていてもよいし、 厚さ方向または幅方向に複数設けられて ヽてもよ ヽ。  A single elastic sheet may be provided between the scraper and the support member, or a plurality of elastic sheets may be provided in the thickness direction or the width direction.
また、この弾性シートは、卷取体に設けられていてもよいし、支持部材に設けられて いてもよぐあるいは、開閉体に設けられていてもよい。  The elastic sheet may be provided on the scraper, may be provided on the support member, or may be provided on the opening / closing body.
[0012] また、第二の発明では、上記弾性シートは、上記卷取体の外周面に巻かれているこ とを特徴とする。  [0012] In addition, the second invention is characterized in that the elastic sheet is wound around an outer peripheral surface of the scraper.
[0013] また、第三又は第六の発明では、上記開閉体の閉鎖方向端部を当接対象部位に 接触させた閉鎖状態で、該開閉体における開放方向側の部分が、上記卷取体に対 し少なくとも一周以上余卷きされるようにした開閉装置であって、上記弾性シートは、 上記卷取体の外周面と前記余巻き部分との間に介在されていることを特徴とする。 [0014] ここで、上記余巻き部分とは、上記開閉体の閉鎖方向端部が当接対象部位 (例え ば、床面や、地面、枠部材等)に接触した閉鎖状態で、上記卷取体力 繰り出されず に該卷取体の周囲に残され巻かれて!/、る開閉体の一部分を意味する。 [0013] In the third or sixth aspect of the invention, in the closed state in which the closing direction end of the opening / closing body is in contact with the contact target portion, the opening direction side portion of the opening / closing body is the cutting body. An opening / closing device that is provided with at least one more turn with respect to the elastic sheet, wherein the elastic sheet is interposed between an outer peripheral surface of the scraper and the extra winding portion. . [0014] Here, the surplus winding portion refers to the scraped state in a closed state in which the end in the closing direction of the opening / closing body is in contact with a contact target portion (for example, a floor surface, the ground, a frame member, etc.). It means a part of the opening / closing body that is left unrolled around the harvesting body without being fed out!
この余巻き部分は、耐火性を有さない材料カゝら構成されていてもよいが、好ましくは 耐火性を有する材料力も構成する。この好ましい構成によれば、火災時等の火炎が 卷取体や弾性シートに対し直接接触するのを、耐火性を有する余巻き部分により阻 むことができ、ひいては、卷取体の過剰な温度上昇による溶融や、弾性シートの燃焼 等を、一層し難くすることができる。  This extra winding portion may be composed of a material cover that does not have fire resistance, but preferably also constitutes a material force that has fire resistance. According to this preferable configuration, it is possible to prevent the flame during fire or the like from coming into direct contact with the scooping body or the elastic sheet by the extra winding portion having fire resistance, and consequently, the excessive temperature of the scissoring body. Melting due to ascending and combustion of the elastic sheet can be made more difficult.
[0015] また、第四又は第七の発明では、前記開閉体には、貫通状の通過口を備えるととも に、該通過口を開閉するように、該通過口及び該通過口の周囲部分に可撓性シート 材からなる扉部が重ね合わせられ、前記支持部材は、前記通過口及び前記扉部を 開閉体幅方向へ避けるようにして配設されて ヽることを特徴とする。  [0015] In the fourth or seventh aspect of the invention, the opening / closing body includes a through-passage opening, and the passage opening and a portion around the passage opening are configured to open and close the passage opening. A door portion made of a flexible sheet material is overlaid, and the support member is disposed so as to avoid the passage port and the door portion in the opening / closing body width direction.
[0016] また、上記通過口とは、上記開閉体本体を貫通した開口部であって、上記開閉体 が閉鎖状態の際に人や物等の通過物を通過可能な状態であればよい。  [0016] The passing port may be an opening that penetrates the opening / closing body main body, and may be in a state in which a passing object such as a person or an object can pass when the opening / closing body is in a closed state.
[0017] また、「前記支持部材は、前記通過口及び前記扉部を開閉体幅方向へ避けるよう にして配設されている」とは、より具体的に説明すれば、上記開閉体が上記卷取体に 巻き取られた際に、上記開閉体における上記通過口及び扉部の部分が、上記支持 部材に接触することがないように、上記支持部材を開閉体幅方向へずらした構成の ことである。  [0017] Further, "the support member is disposed so as to avoid the passage opening and the door portion in the width direction of the opening / closing body" is more specifically described. The support member is configured to be shifted in the opening / closing body width direction so that the passage opening and the door portion of the opening / closing body do not come into contact with the support member when wound around the take-up body. That is.
[0018] また、第五又は第八の発明では、上記卷取体が複数の卷取体構成部材を軸方向 へ連結してなり、上記支持部材は、前記複数の卷取体構成部材の内の各々に対し、 複数設けられて 、ることを特徴とする。  [0018] In the fifth or eighth aspect of the invention, the scooping body connects a plurality of scooping body constituent members in the axial direction, and the support member is a member of the scooping body constituent members. For each of the above, a plurality of them are provided.
[0019] なお、好ましい態様として、上記弾性シートは、上記開閉体が上記卷取体に巻かれ るのに伴って上記卷取体の周囲に卷かれるように設けられて 、てもよ 、。 [0019] As a preferred aspect, the elastic sheet may be provided so as to be wound around the scooping body as the opening / closing body is wound around the scooping body.
この態様によれば、開閉体が卷取体に巻かれるのに伴って卷取体の周囲に弹性シ 一トが卷かれ、その弾性シートが卷取体と支持部材との間に介在されることになる。 したがって、開閉体及び Z又は支持部材が局部的な押圧力により破損したり耐久 性の低下を生じたり等するのを、弾性シートの弾性によって、し難くすることができる。 なお、この構成の具体例としては、上記弾性シートを上記開閉体に部分的または全 体的に止着した態様が挙げられ、この態様によれば、上記開閉体が上記卷取体に卷 かれるのに伴って、上記弾性シートが上記卷取体の周囲に巻かれることになる。また 、この態様において、上記弾性シートは、上記卷取体に巻かれた際の上記開閉体の 内周面側に配設されるのが好ましいが、上記卷取体に巻かれた際の上記開閉体の 外周面側に配設することも可能である。 According to this aspect, as the opening / closing body is wound around the catcher, the inertia sheet is wound around the catcher, and the elastic sheet is interposed between the catcher and the support member. It will be. Therefore, it is possible to make it difficult for the opening and closing body and the Z or the support member to be damaged by the local pressing force or to deteriorate the durability due to the elasticity of the elastic sheet. A specific example of this configuration is an embodiment in which the elastic sheet is partially or wholly fixed to the opening / closing body. According to this embodiment, the opening / closing body is placed on the scraping body. Accordingly, the elastic sheet is wound around the scraper. Further, in this aspect, the elastic sheet is preferably disposed on the inner peripheral surface side of the opening / closing body when wound on the scraper, but the elastic sheet is wound on the scraper. It can also be arranged on the outer peripheral surface side of the opening / closing body.
また、他例としては、上記弾性シートの開閉体開放方向側の端部を、上記卷取体の 外周面に止着し、他端側を垂れ下げるようにした態様が挙げられ、この態様によって も、上記開閉体が上記卷取体に巻かれるのに伴って、上記弾性シートが上記卷取体 の周囲に巻かれることになる。  As another example, there is an embodiment in which the end of the elastic sheet on the opening / closing body opening direction side is fixed to the outer peripheral surface of the scraper and the other end is suspended. In addition, as the opening / closing body is wound around the scooping body, the elastic sheet is wound around the scooping body.
更に、他例としては、上記弾性シートの開閉体開放方向側の端部を、上記卷取体 の外周面に止着し、他端側を上記開閉体に止着した態様が挙げられる。この態様に よれば、前記態様と略同様の作用効果が得られる上、上記開閉体の保持強度を向 上することができる。  Further, as another example, there is a mode in which the end of the elastic sheet on the opening / closing body opening direction side is fixed to the outer peripheral surface of the scraper and the other end side is fixed to the opening / closing body. According to this aspect, it is possible to obtain substantially the same operational effects as in the above aspect and to improve the holding strength of the opening / closing body.
更に、他例としては、上記弾性シートの開閉体開放方向側の端部を、上記卷取体 に余卷きされた上記開閉体と、上記卷取体との間に挟み込むことで保持するようにし た態様が挙げられ、この態様によっても、上記開閉体が上記卷取体に巻かれるのに 伴って、上記弾性シートが上記卷取体の周囲に巻かれることになる。この態様におけ る上記弾性シートの開閉体閉鎖方向側の部分は、止着されず垂れ下がった状態でも よいし、上記開閉体に止着されていてもよい。  Further, as another example, the end of the elastic sheet on the opening / closing body opening direction side is held by being sandwiched between the opening / closing body surplused by the scraper and the scraper. In this embodiment, the elastic sheet is wound around the scooping body as the opening / closing body is wound around the scooping body. The part of the elastic sheet on the opening / closing body closing direction side in this aspect may be in a state of hanging down without being fastened, or may be fastened to the opening / closing body.
また、好ましい態様として、上記支持部材を上記卷取体の軸方向へわたって所定 間隔置きに複数設けるとともに、各支持部材を上記卷取体の外周面に接触して回動 可能な一対のローラにより構成し、これら複数の支持部材の内、上記通過口及び上 記扉部に最も近い支持部材について、一対のローラにおけるローラ間隔を、他の支 持部材を構成する一対のローラにおけるローラ間隔よりも狭くしてもよい。  Further, as a preferred embodiment, a plurality of the support members are provided at predetermined intervals over the axial direction of the scooping body, and a pair of rollers that can rotate by contacting each supporting member with the outer peripheral surface of the scooping body. Among the plurality of support members, with respect to the support member closest to the passage port and the door portion, the roller interval between the pair of rollers is greater than the roller interval between the pair of rollers constituting the other support member. May be narrowed.
すなわち、卷取体を支持する複数の支持部材について、通過口及び扉部を避ける ようにして配置すると、卷取体軸方向における所定距離あたりの支持部材の配設数 が、通過口及び扉部に近い部分で少なくなる。そのため、通過口及び扉部に近い支 持部材は、他の支持部材と比較し、卷取体力 受ける荷重が大きくなる。 That is, when a plurality of support members that support the scraper are arranged so as to avoid the passage opening and the door, the number of support members disposed per predetermined distance in the shaft direction of the scraper is determined as the passage opening and the door. It becomes less near the part. Therefore, the support close to the passage opening and door Compared with other support members, the holding member is subjected to a greater load on the gripping body.
そこで、前記態様では、複数の支持部材の内、通過口及び扉部に最も近い支持部 材について、該支持部材を構成する一対のローラにおけるローラ間隔を、他の支持 部材を構成する一対のローラにおけるローラ間隔よりも狭くし、一対のローラを構成 する各ローラが卷取体力 受ける荷重を軽減して 、る。  So, in the said aspect, about the support member nearest to a passage port and a door part among several support members, the roller space | interval in a pair of roller which comprises this support member is used as a pair of roller which comprises another support member. The distance between the rollers is narrower, and the load that each roller constituting the pair of rollers receives on the body force is reduced.
したがって、前記態様によれば、卷取体を支持する支持部材の耐久性を、一層向 上することができる。  Therefore, according to the aspect, the durability of the support member that supports the scraper can be further improved.
[0021] また、特に、開閉体に可撓性シート部を有する場合に、該可撓性シート部の耐久性 を向上する観点力 は、以下の態様が提案される。  [0021] In particular, when the opening / closing body has a flexible sheet portion, the following aspects are proposed as the viewpoint power to improve the durability of the flexible sheet portion.
この態様は、少なくとも開放方向端部側に可撓性シート部を有する開閉体と、該開 閉体における可撓性シート部を外周面に止着した卷取体とを備え、該開閉体を該卷 取体により巻き取ったり繰り出したりするようにした開閉装置にぉ 、て、前記可撓性シ ート部が、開閉体幅方向へわたる橈みを有する状態で前記卷取体の外周面に止着 されていることを特徴とする。  This embodiment includes an opening / closing body having a flexible sheet portion at least on the end side in the opening direction, and a scissors body that fastens the flexible sheet portion of the opening / closing body to the outer peripheral surface. An opening / closing device that is wound or unwound by the winding body, and the flexible sheet portion has a stagnation extending in the opening / closing body width direction. It is characterized by being fixed to the surface.
この態様によれば、可撓性シート部の橈み部分によって、可撓性シート部に開閉体 幅方向の張力が作用するのを軽減することができる。  According to this aspect, it is possible to reduce the tension in the width direction of the opening / closing body acting on the flexible sheet portion by the stagnation portion of the flexible sheet portion.
ひいては、風圧や、開閉時の振動、寸法精度のバラツキ等に起因して、可撓性シ ート部に開閉体幅方向の張力やねじれ荷重等が作用し、該可撓性シート部が損傷し たり等するのをし難くし、可撓性シート部の耐久性を向上することができる。  As a result, due to wind pressure, vibration during opening and closing, variation in dimensional accuracy, tension and torsional load in the width direction of the opening / closing body acts on the flexible sheet, and the flexible sheet is damaged. Or the like, and the durability of the flexible sheet portion can be improved.
[0022] また、火災等に起因する過剰な温度上昇により、卷取体が溶融等して、開閉体が 落下してしまうのを防ぐようにする観点力 は、以下の態様が提案される。 [0022] Further, the following aspects are proposed as viewpoint powers for preventing the open / close body from dropping due to an excessive temperature rise caused by a fire or the like and melting of the scraper.
この態様は、開閉体を巻き取ったり繰り出したりする略中空状の卷取体と、該卷取 体をその内部側力 支持する中子とを備え、前記卷取体及び中子を回転させること により前記開閉体を動作するようにした開閉装置において、前記中子を前記卷取体 よりも耐火性の高い材料により形成し、前記開閉体を前記中子に対し止着するように したことを特徴とする。  This aspect includes a substantially hollow scooping body that winds and unwinds the open / close body, and a core that supports the scooping body on its internal side, and rotates the scooping body and the core. In the opening / closing device configured to operate the opening / closing body, the core is formed of a material having higher fire resistance than the scraper body, and the opening / closing body is fixed to the core. Features.
この態様によれば、例えば火災等に起因する過剰な温度上昇により、卷取体が溶 融等したとしても、開閉体が卷取体よりも耐火性の高い中子に止着されているため、 その開閉体が落下してしまうようなことを、防止することができる。 According to this aspect, for example, even if the trimming body is melted due to an excessive temperature rise caused by a fire or the like, the opening / closing body is fixed to the core having higher fire resistance than the trimming body. , It is possible to prevent the opening / closing body from falling.
[0023] また、好ましい態様として、略中空状の卷取体構成部材をその内部側から上記中 子により支持し、該卷取体構成部材に貫通される複数の止着具を内部の中子に止 着することで、これら卷取体構成部材と中子とを一体化し、この一体化された卷取体 構成部材および中子を軸方向へ複数設けるとともに、隣り合う卷取体構成部材内の 中子同士を軸部材によって連結することで上記卷取体を構成し、この卷取体を、その 下方側において開閉体幅方向へ配設された複数の支持部材により回動可能に受け るようにした開閉装置であって、前記卷取体構成部材には、前記止着具を貫通させ るための貫通孔が、周方向へわたって複数設けられ、これら複数の貫通孔の内の一 部は、前記止着具を卷取体軸方向へ移動可能にする長孔とした構成であってもよい この態様によれば、卷取体の周囲に開閉体が巻かれ、開閉体幅方向において偏つ た巻き太り箇所が生じた場合でも、長孔の作用により隣り合う卷取体構成部材間を折 れ曲がるように変形するため、卷取体下方側の複数の支持部材の内の一部に偏った 負荷が加わるのを防ぐことができる。  [0023] Further, as a preferable aspect, a substantially hollow scooping member constituting member is supported from the inside by the core, and a plurality of fasteners penetrating the scooping member constituting member are provided. By fixing to the above-mentioned trimming body constituting member and the core, a plurality of these trimming body constituting members and cores are provided in the axial direction, and in the adjacent trimming body constituting member. The core is connected to each other by a shaft member to form the scooping body, and the scooping body is rotatably received by a plurality of support members arranged in the width direction of the opening / closing body on the lower side thereof. An opening / closing device configured as described above, wherein the through-hole constituting member is provided with a plurality of through-holes for allowing the fasteners to pass therethrough in a circumferential direction, and one of the plurality of through-holes is provided. The part has a long hole that allows the fastener to be moved in the axial direction of the scraper. According to this aspect, even when the opening / closing body is wound around the scooping body and an unevenly thickened portion is generated in the width direction of the opening / closing body, the adjacent scooping body constituting members are caused by the action of the long holes. Therefore, it is possible to prevent an unbalanced load from being applied to a part of the plurality of support members on the lower side of the harvesting body.
すなわち、仮に、卷取体構成部材と中子とを丸孔のみを貫通する止着具により一体 化した場合には、卷取体の周囲に開閉体幅方向において偏った巻き太り箇所が生じ た場合、その巻き太り箇所に近い支持部材に、比較的大きな負荷が加わるとともに、 その負荷よりも小さ 、負荷が他の支持部材に加わり、開閉体幅方向にぉ 、て支持部 材に加わる負荷の偏りを生じるおそれがある。  In other words, if the trimming member constituting member and the core are integrated by a fastening tool that penetrates only the round hole, winding thickening portions that are biased in the width direction of the opening / closing body are generated around the trimming body. In this case, a relatively large load is applied to the support member close to the thickened part of the winding, and the load applied to the other support member is smaller than the load, and the load applied to the support member is reduced in the opening / closing body width direction. There is a risk of bias.
し力しながら、この態様では、卷取体構成部材に対し中子が長孔の箇所で卷取体 軸方向へ若干移動可能であるため、隣り合う二つの卷取体構成部材間が折れ曲が るように柔軟に変形する。そのため、巻き太り箇所に近い支持部材とそれ以外の支持 部材とに、負荷が分散される。  However, in this aspect, since the core is slightly movable in the axial direction of the cutting body with respect to the cutting body constituting member, the two adjacent cutting body constituting members can be bent. Deforms flexibly so that Therefore, the load is distributed to the support member close to the thickened portion and the other support members.
[0024] また、開閉体の厚肉部に起因する不具合を低減するためには、以下の態様が提案 される。 [0024] In addition, the following modes are proposed in order to reduce problems caused by the thick part of the opening / closing body.
この態様は、開閉体を卷取体に巻き取ったり巻き戻したりすることで開閉動作させる ようにした開閉装置において、前記開閉体には、その幅方向における他の部位よりも 肉厚の大きい厚肉部が設けられ、前記卷取体は、前記厚肉部に対応する部位が、他 の部位よりも縮径されて 、ることを特徴とする。 According to this aspect, in the opening / closing apparatus configured to open and close by winding or unwinding the opening / closing body on the winding body, the opening / closing body is provided with more than the other parts in the width direction. A thick-walled portion having a large thickness is provided, and the scraper is characterized in that a portion corresponding to the thick-walled portion is reduced in diameter as compared with other portions.
この構成によれば、開閉体を卷取体に巻き取った際に、巻き取られた開閉体にお ける厚肉部に対応する部位が、他の部位よりも巻き太りしてしまうのを防ぐことができ る。  According to this configuration, when the opening / closing body is wound around the take-up body, the portion corresponding to the thick portion of the wound opening / closing body is prevented from becoming thicker than other portions. be able to.
よって、収納状態における開閉体の閉鎖方向端部 (例えば座板部材)が、橈んでし まい外観状の体裁を損ねてしまったり、厚肉部に対応する箇所で開閉体に生じる開 閉方向の張力に偏りが生じ、該開閉体の耐久性が低下してしまったり等、厚肉部に 起因する不具合を低減することができる。  Therefore, the closing direction end portion (for example, the seat plate member) of the opening / closing body in the stowed state is damaged, and the appearance of the opening / closing body is damaged. It is possible to reduce problems caused by the thick-walled portion, such as a bias in tension and a decrease in durability of the opening / closing body.
しカゝも、卷取体を部分的に縮径した構造であるため、開閉体及び卷取体を軽量ィ匕 することができ、ひいては、卷取体の橈み抑制や、卷取体を回転させる駆動源の負 荷軽減、開閉体及び卷取体のコストダウン等、様々な効果を発揮することができ、特 に、開閉体幅方向の寸法が比較的長い開閉装置において、その作用効果を顕著に 発揮することができる。  Shika also has a structure in which the cutting body is partially reduced in diameter, so that the opening and closing body and the cutting body can be reduced in weight. Various effects can be achieved, such as reducing the load on the rotating drive source and reducing the cost of the opening and closing body and the tapping body, especially in the case of an opening and closing device with relatively long dimensions in the opening and closing body width direction. Can be remarkably exhibited.
[0025] なお、本明細書中において「開閉体厚さ方向」とは、閉鎖状態の上記開閉体の厚さ 方向を意味する。  In the present specification, “opening / closing body thickness direction” means the thickness direction of the opening / closing body in a closed state.
また、本明細書中において「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、上記開閉体の厚さ方向ではない方向を意味する。  Further, in this specification, the “opening / closing body width direction” means a direction that is substantially orthogonal to the opening / closing direction of the opening / closing body and is not the thickness direction of the opening / closing body.
また、本明細書中において「開閉体開閉方向」とは、開閉体が空間を仕切ったり開 放したりするためにスライドする方向を意味する。  Further, in this specification, the “opening / closing body opening / closing direction” means a direction in which the opening / closing body slides in order to partition or open the space.

したがって、卷取体から開閉体が繰り出された際に、弾性シートが垂れ下がって外 観上の体裁を損ねてしまうのを防ぐことができる。  Therefore, it is possible to prevent the appearance of the elastic sheet from sagging when the opening / closing body is drawn out from the take-up body and damaging the appearance.
その上、弾性シートを卷取体に止着する構造を簡素なものにして、生産性を向上す ることちでさる。  In addition, it is possible to improve productivity by simplifying the structure for fixing the elastic sheet to the scraper.
[0029] 更に、第四又は第七の発明によれば、支持部材が通過口及び扉部を避けた位置 に配置されているため、開閉体を卷取体に巻き取った際に、通過口及び扉部に対応 する卷太り部分が支持部材によって比較的強く押圧されてしまうのを防ぐことができる 。ひいては、開閉体における扉部近傍の部分や、可撓性シート材カ なる扉部等が 破損してしまったり、卷取体を支持する支持部材の耐久性が低下してしまったり等す るのを防ぐことができる。  [0029] Further, according to the fourth or seventh invention, since the support member is disposed at a position avoiding the passage opening and the door portion, the passage opening is formed when the opening / closing body is wound around the take-up body. In addition, it is possible to prevent the thickened portion corresponding to the door portion from being pressed relatively strongly by the support member. As a result, the portion near the door of the opening / closing body, the door that is the flexible sheet material, etc. may be damaged, or the durability of the support member that supports the scraper may be reduced.

実施の形態による一例は、住宅やビル、倉庫、工場、地下街、トンネル、車両の荷 台等の構築'構造物の開口部分や、構築'構造物の内部に配設され、前記開口部分 を開閉したり、構築'構造物内部の空間を仕切ったり開放したりする開閉装置であつ て、特に、開閉体の略全域を可撓性シート材によって形成しているスクリーンシャツタ 一装置として好ま 、開閉装置つ!/、て説明する。  An example according to the embodiment is an opening part of a construction 'structure, such as a house, building, warehouse, factory, underground mall, tunnel, vehicle loading platform, etc. It is an open / close device that partitions and opens the space inside the structure, and is particularly preferred as a screen shirt device that forms a flexible sheet material over the entire area of the open / close body. Explain the device!
[0032] この開閉装置 1は、可撓性シート部 11を有する開閉体 10と、該開閉体 10を巻き取 つたり繰り出したりして開閉動作させる卷取体 20と、該卷取体 20及び該卷取体に卷 かれた際の可撓性シート部 11をその下方側力 回動可能に受ける支持部材 30と、 開閉体 10をその幅方向の両端部で開閉方向へ案内するガイドレール(図示せず)と を具備している。 [0032] The opening / closing device 1 includes an opening / closing body 10 having a flexible sheet part 11, a scissor body 20 that winds and unwinds the opening / closing body 10 to open / close, and the scooping body 20 and卷 on the body A support member 30 that receives the flexible sheet portion 11 so that the downward force of the flexible sheet portion 11 can be rotated, and a guide rail (not shown) that guides the opening and closing body 10 in the opening and closing direction at both ends in the width direction. It has.
[0033] 開閉体 10は、該開閉体 10の略全域を構成している可撓性シート部 11と、該可撓 性シート部 11の開閉体開放方向側の端部に設けられた止着部材 12 (図 2参照)と、 該可撓性シート部 11の開閉体閉鎖方向側の端部に設けられた座板部材 15とを備え ている。  [0033] The opening / closing body 10 includes a flexible sheet portion 11 constituting substantially the entire area of the opening / closing body 10, and a fastening member provided at an end of the flexible sheet portion 11 on the opening / closing body opening direction side. A member 12 (see FIG. 2) and a seat plate member 15 provided at the end of the flexible sheet portion 11 on the opening / closing body closing direction side are provided.
[0034] 可撓性シート部 11は、後述する卷取体 20を構成する複数の卷取体構成部材 21に それぞれ対応するように、複数のシート部構成部材 11aを開閉体幅方向へ連設し、 隣り合うシート部構成部材 11a, 11a間を着脱可能な止着手段 (例えば、ボタンゃホ ック、スライドファスナーや面ファスナー、磁石、ねじ、ボルトとナットなど)によって接 続するとともに、その接続箇所において開閉体幅方向の張力を逃がすように開閉体 幅方向に橈みを形成して 、る。  [0034] The flexible sheet portion 11 includes a plurality of sheet portion constituent members 11a arranged in the width direction of the opening / closing body so as to correspond to a plurality of scooping member constituent members 21 constituting a scooping body 20 described later. In addition, the adjacent seat member 11a is connected by a detachable fastening means (for example, a button hook, a slide fastener, a hook-and-loop fastener, a magnet, a screw, a bolt and a nut), and the like. A sag is formed in the width direction of the opening / closing body so as to release the tension in the width direction of the opening / closing body at the connection point.
[0035] 各シート部構成部材 11aは、開閉体幅方向へ連設された複数のシート材 l lalを、 端部側同士で重ね合わせ (図 3参照)、その重ね合わせ部分を開閉体開閉方向へわ たって縫!、付けることで構成されて 、る。  [0035] Each sheet member 11a has a plurality of sheet materials l lal arranged continuously in the opening / closing body width direction overlapped on the end side (see Fig. 3), and the overlapped portion is formed in the opening / closing body opening / closing direction. It consists of sewing and attaching.
各シート材 l lalは、例えば、ガラスクロスやシリカクロス等の難燃性布地や、フッ素 加工を施した塩ィ匕ビュル榭脂シート材、ガラス繊維を含んだ合成樹脂シート材等、難 燃性又は不燃性等の耐火性を有する可撓性シート材料カゝらなる。  Each sheet material l lal is, for example, a flame retardant fabric such as glass cloth or silica cloth, a salty vule resin sheet material treated with fluorine, a synthetic resin sheet material containing glass fiber, etc. Alternatively, a flexible sheet material having fire resistance such as incombustibility is obtained.
[0036] なお、図示例によれば、開閉体幅方向へ並ぶ複数のシート材 l lalからシート部構 成部材 11aを構成している力 開閉体開閉方向へ並ぶ複数のシート材力 シート部 構成部材 11aを構成したり、開閉体幅方向および開閉体開閉方向へ並ぶ複数のシ ート材力 シート部構成部材 1 laを構成することも可能である。  [0036] According to the illustrated example, a plurality of sheet materials arranged in the width direction of the opening / closing body llal constitutes a force constituting the sheet portion constituting member 11a A plurality of sheet material forces arranged in the opening / closing direction of the opening / closing body It is also possible to configure the member 11a or to configure a plurality of sheet material force sheet member constituting members 1la arranged in the opening / closing body width direction and the opening / closing body opening / closing direction.
[0037] また、シート部構成部材 1 laを複数のシート材 1 lalを縫 ヽ付けて構成した場合、 図 3に示すように、その縫付け部分 nl, n2は複数列設けられ、その複数列の縫い付 け部分 nl, n2の内、少なくとも一列がステンレス繊維を主原料とする縫糸によって縫 い付けられるのが好ましい。この構成によれば、例えば、万が一火災が発生した場合 等であっても、縫糸が全て焼損して、隣り合うシート材同士が分離してしまうのを防ぐ ことができ、ひいては可撓性シート部 11の耐火性能を向上することができる。 [0037] Further, when the sheet member constituting member 1 la is configured by sewing a plurality of sheet materials 1 lal, as shown in FIG. 3, the sewing parts nl and n2 are provided in a plurality of rows, and the plurality of rows are provided. It is preferable that at least one row of the sewn portions nl and n2 is sewn with a sewing thread mainly composed of stainless steel fibers. According to this configuration, for example, even in the event of a fire, it is possible to prevent the sewn thread from being burnt out and separating adjacent sheet materials from each other. As a result, the fire resistance of the flexible sheet portion 11 can be improved.
また、更には、前記ステンレス繊維の縫糸以外の縫糸を,合成樹脂繊維を主原料と する縫糸とすれば、通常使用時には、合成樹脂繊維を主原料とする縫糸によって隣 り合うシート材間の弾力性を維持することができる。  Furthermore, if the sewing thread other than the stainless steel thread is made of synthetic resin fiber as the main raw material, the elasticity between adjacent sheet materials by the synthetic resin fiber as the main raw material is used during normal use. Sex can be maintained.
[0038] そして、各シート部構成部材 11aの開閉体開放方向側の端部は、縦断面袋状に形 成され、その袋状部分には、開閉体幅方向へわたって止着部材 12が挿入されてい る(図 2参照)。  [0038] Then, an end of each seat part constituting member 11a on the opening / closing body opening direction side is formed in a longitudinal cross-section bag shape, and a fastening member 12 is formed in the bag-like portion across the opening / closing body width direction. Has been inserted (see Figure 2).
この止着部材 12は、卷取体 20の各卷取体構成部材 21と略同一長さの棒状の部 材であり、図示した好ましい一例によれば、縦断面矩形棒状の部材としている。 この止着部材 12の材質は、剛性材料であればよぐ特に、耐火性および生産性を 向上する観点より、鋼材やステンレス材等の金属材料とするのが好ましいが、他例と しては、硬質剛性榭脂材料や、木材、セラミック材、石材等とすることも可能である。  The fastening member 12 is a rod-like member having substantially the same length as each of the catching body constituting members 21 of the catching body 20, and according to a preferred example illustrated, the fastening member 12 is a member having a rectangular bar shape in vertical section. The material of the fastening member 12 is not particularly limited as long as it is a rigid material. In particular, from the viewpoint of improving fire resistance and productivity, a metal material such as steel or stainless steel is preferable. It is also possible to use a hard rigid resin material, wood, ceramic material, stone material or the like.
[0039] また、可撓性シート部 11における開閉体幅方向の張力を逃がすための工夫として は、以下のようにしてもよい。 [0039] Further, as a device for releasing the tension in the opening / closing body width direction in the flexible sheet portion 11, the following may be employed.
例えば、上記可撓性シート部 11には、止着具 14を挿通させるための貫通孔が開閉 体幅方向へわたって複数配設され、止着部材 12には、前記止着具 14を貫通させる ための貫通孔が開閉体幅方向へわたって複数配設され、卷取体 20には、前記止着 具 14の先端を止着するための被止着部が開閉体幅方向へわたって複数配設され、 止着部材 12の複数の貫通孔の配設ピッチと卷取体 20の複数の被止着部の配設ピ ツチとを略同一ピッチにするとともに、これら貫通孔及び被止着部の配設ピッチよりも 、可撓性シート部 11の複数の貫通孔の配設ピッチを長くしてもよい(図示せず)。 この態様によれば、止着部材 12により可撓性シート部 11を卷取体 20に止着する際 の作業性を向上することができるのは勿論のこと、可撓性シート部 11の貫通孔の配 設ピッチが止着部材 12の貫通孔及び卷取体 20の被止着部の配設ピッチよりも長い ため、可撓性シート部 11の貫通孔間の部分に橈みを形成することができる。  For example, the flexible sheet portion 11 is provided with a plurality of through holes through which the fasteners 14 are inserted in the opening / closing body width direction, and the fastening member 12 penetrates the fasteners 14. A plurality of through-holes are provided in the width direction of the opening / closing body, and a securing portion for fixing the tip of the fastening tool 14 extends in the width direction of the opening / closing body. A plurality of through holes of the fixing member 12 and the arrangement pitches of the plurality of to-be-attached portions of the catching body 20 are set to have substantially the same pitch. The arrangement pitch of the plurality of through holes in the flexible sheet portion 11 may be made longer than the arrangement pitch of the landing portions (not shown). According to this aspect, it is possible to improve the workability when the flexible sheet portion 11 is fixed to the scooping body 20 by the fixing member 12, as well as to penetrate the flexible sheet portion 11. Since the arrangement pitch of the holes is longer than the arrangement pitch of the through-holes of the fastening member 12 and the to-be-fixed portion of the grind body 20, stagnation is formed in the portion between the through-holes of the flexible sheet portion 11. be able to.
[0040] また、他の好ましい態様としては、上記開閉装置 1から止着部材 12を省き、可撓性 シート 11を卷取体に直接止着するようにした態様にぉ 、て、上記可撓性シート部 11 に、卷取体 20の外周面に止着される止着部(具体的には貫通孔)を開閉体幅方向 へわたって複数配設し、卷取体 20には、上記可撓性シート部 11の前記止着部の各 々が止着される被止着部(具体的にはネジ孔)を、前記止着部の数に対応して複数 配設し、前記止着部の配設ピッチを前記被止着部の配設ピッチよりも長くしてもよ!ヽ( 図示せず)。 [0040] As another preferred embodiment, the flexible member 11 is directly fixed to the scraper body by omitting the fixing member 12 from the opening / closing device 1, and the flexible member 11 In the opening / closing body width direction, a fixing portion (specifically, a through hole) that is fixed to the outer peripheral surface of the trimming body 20 is attached to the adhesive sheet portion 11 A plurality of covering members 20 are provided, and a fixing portion (specifically, a screw hole) to which each of the fixing portions of the flexible sheet portion 11 is fixed is provided on the scooping body 20. A plurality of fixing portions may be provided corresponding to the number of fixing portions, and the arrangement pitch of the fixing portions may be longer than the arrangement pitch of the to-be-attached portions (not shown).
この態様によれば、可撓性シート部 11の止着部間のピッチが卷取体 20の被止着 部間のピッチよりも長いため、可撓性シート部 11における止着部間に、開閉体幅方 向の張力を逃がす橈みを形成することができる。  According to this aspect, since the pitch between the fastening portions of the flexible sheet portion 11 is longer than the pitch between the fastened portions of the grind body 20, between the fastening portions in the flexible sheet portion 11, It is possible to form a sag that releases tension in the width direction of the opening / closing body.
[0041] また、好ましい態様として、隣り合う卷取体構成部材 21, 21間に対応する範囲に、 可撓性シート部 11の橈み部分を形成するようにしてもょ 、。 [0041] In addition, as a preferred embodiment, the squeezed portion of the flexible sheet portion 11 may be formed in a range corresponding to between the adjacent scraper constituting members 21 and 21.
この態様によれば、可撓性シート部 11が、隣り合う卷取体構成部材 21, 21間の空 間に入り込むようにして部分的に橈む。  According to this aspect, the flexible sheet portion 11 is partially pinched so as to enter the space between the adjacent scraper constituting members 21 and 21.
すなわち、卷取体構成部材 21, 21間の空間を利用して、可撓性シート部 11を比 較的大きく橈ませることができ、ひいては、可撓性シート部 11に開閉体幅方向の張 力が作用するのを、一層低減することができる。  In other words, the flexible sheet portion 11 can be relatively large-sized by utilizing the space between the trimming member constituting members 21 and 21, and as a result, the flexible sheet portion 11 is stretched in the opening / closing body width direction. The effect of force can be further reduced.
[0042] また、卷取体 20の各卷取体構成部材 21と後述する支持部材 30との間には、弾性 シート 40が介在される。 [0042] In addition, an elastic sheet 40 is interposed between each scooping body constituting member 21 of the scooping body 20 and a support member 30 described later.
この弾性シート 40は、支持部材 30を構成する各ローラ 31 (又は 32)の軸方向長さ と略同一又は該軸方向長さよりも若干短い幅寸法であって、開閉体開閉方向へわた る略長尺帯状の部材であり、各支持部材 30に接触するように配置され、その開閉体 開放方向側の端部が上記止着部材 12と共に卷取体構成部材 21に止着されている この弾性シート 40の材質は、ゴムや、弾性合成樹脂材料、発泡材等、厚さ方向の 弾性を有する材料とすればょ ヽ。  The elastic sheet 40 has a width dimension that is substantially the same as or slightly shorter than the axial length of each roller 31 (or 32) that constitutes the support member 30, and that extends substantially in the opening / closing direction of the opening / closing body. It is a long belt-like member, and is arranged so as to contact each support member 30, and its end on the opening / closing body opening direction side is fastened to the catching body constituting member 21 together with the fastening member 12. The material of the sheet 40 should be a material having elasticity in the thickness direction, such as rubber, elastic synthetic resin material, and foam material.
[0043] 上記弾性シート 40の止着構造について詳細に説明すれば、開閉体 10の閉鎖方向 端部 (より具体的には座板部材 15)を当接対象部位 y (例えば床面や地面、枠部材 など)に接触させた状態で、該開閉体 10における開放方向側の部分を、上記卷取体 20の卷取体構成部材 21に対し約一周程度余卷きすることで、弾性シート 40が、そ の余巻き部分 Xと卷取体構成部材 21外周面との間に挟まれるようにしてある(図 2参 照)。 [0043] If the fastening structure of the elastic sheet 40 is described in detail, the end portion (more specifically, the seat plate member 15) in the closing direction of the opening / closing body 10 is contacted with the target portion y (for example, floor surface or ground, The elastic sheet 40 is provided by leaving the portion of the opening / closing body 10 on the opening direction side of the opening / closing body 10 with respect to the cutting body constituting member 21 of the cutting body 20 for about one round in contact with the frame member. Is sandwiched between the extra winding portion X and the outer peripheral surface of the trimming member constituting member 21 (see FIG. 2). See).
この構成によれば、弾性シート 40を卷取体 20の外周面に止着する構造を簡素化 できる上、卷取体 20から開閉体 10が繰り出された際に、弾性シート 40が垂れ下がつ て外観上の体裁を損ねてしまうのを防ぐことができる。  According to this configuration, the structure for fixing the elastic sheet 40 to the outer peripheral surface of the grinder 20 can be simplified, and the elastic sheet 40 can hang down when the opening / closing member 10 is extended from the grinder 20. Therefore, it is possible to prevent the appearance from being damaged.
なお、図 1においては、本実施の形態の構成を明瞭に示すために、座板部材 15を 当接対象部位 yに当接させずに、各弾性シート 40を開閉体閉鎖方向へ引き出した状 態としている。  In FIG. 1, in order to clearly show the configuration of the present embodiment, the elastic sheet 40 is pulled out in the opening / closing body closing direction without contacting the seat plate member 15 to the contact target portion y. State.
また、図 2に示す一例によれば、上述したように余巻き部分 Xを有する好ましい態様 を示しているが、この余巻き部分 Xを省いた態様とすることも可能であり、この場合、好 ましくは、弾性シート 40を卷取体 20の外周面または開閉体 10の面に固定した構成と する。  In addition, according to the example shown in FIG. 2, the preferred embodiment having the surplus winding portion X as described above is shown. However, the surplus winding portion X may be omitted. Preferably, the elastic sheet 40 is fixed to the outer peripheral surface of the scraper 20 or the surface of the opening / closing member 10.
[0044] また、卷取体 20は、開閉体幅方向へわたって所定間隔置きに配設された複数の卷 取体構成部材 21を、それぞれ内部側力も中子 23 (図 2参照)および軸部材 22により 支持するとともに連結することで構成されている。  [0044] Further, the scooping body 20 has a plurality of scooping body constituting members 21 arranged at predetermined intervals over the width direction of the opening / closing body. It is configured by being supported and connected by a member 22.
[0045] 各卷取体構成部材 21は、比較的軽量な金属材料力もなる略円筒状の部材であり、 その外周面に軸方向へわたる凹部 21aを備え、該凹部 21aに止着部材 12を嵌め合 わせることで、止着部材 12の遠心方向への突出量を小さくするとともに、止着部材 1[0045] Each of the scooping body constituting members 21 is a substantially cylindrical member having a relatively light metal material force, and has a concave portion 21a extending in the axial direction on the outer peripheral surface thereof, and a fastening member 12 is provided in the concave portion 21a. By fitting, the amount of protrusion of the fastening member 12 in the centrifugal direction is reduced, and the fastening member 1
2の脱落をし難くしている。 It is difficult for 2 to fall off.
この構成によれば、卷取体 21に巻かれたシート部構成部材 11aの巻き太りを軽減 することができ、また、支持部材 30との摩擦等によって、シート部構成部材 11aが磨 耗ゃ破損等してしまうおそれを低減することができる。  According to this configuration, it is possible to reduce the thickening of the sheet component member 11a wound around the scraper 21, and if the sheet component component 11a is worn or damaged due to friction with the support member 30, etc. It is possible to reduce the risk of being equal.
[0046] また、中子 23は、卷取体構成部材 21よりも耐火性の高い材料、より具体的には、卷 取体構成部材 21よりも融点の高い金属材料によって形成されている。 In addition, the core 23 is formed of a material having higher fire resistance than that of the trimming body component member 21, more specifically, a metal material having a melting point higher than that of the trimming body component member 21.
例えば、卷取体構成部材 21をアルミニウム合金カゝら形成した場合、中子 23の材質 は、アルミニウム合金よりも融点の高い金属材料、例えば鋼材やステンレス材等とさ れる。  For example, when the scraper constituting member 21 is formed of an aluminum alloy cover, the material of the core 23 is a metal material having a melting point higher than that of the aluminum alloy, such as a steel material or a stainless steel material.
また、隣り合う中子 23, 23を連結する軸部材 22の材質も、強度や耐火性等の観点 より、鋼材やステンレス材等とするのが好ましい。 [0047] そして、シート部構成部材 11aおよび止着部材 12には、卷取体軸方向および周方 向にわたつて配設された複数の止着具 14 (例えば、鋼材やステンレス材等力 なる 耐火性を有するネジゃボルト等)が挿通され、各止着具 14の先端が上記中子 23に 螺合される。 In addition, the material of the shaft member 22 that connects the adjacent cores 23 and 23 is preferably a steel material, a stainless steel material, or the like from the viewpoint of strength, fire resistance, and the like. [0047] A plurality of fasteners 14 (for example, steel or stainless steel or the like are provided on the seat portion constituting member 11a and the fastening member 12 are provided in the axial direction and the circumferential direction of the scraper body. A fire-resistant screw bolt or the like is inserted, and the tip of each fastener 14 is screwed into the core 23.
この構成によれば、仮に火災時等の過剰な温度上昇により卷取体構成部材 21が 溶融したとしても、シート部構成部材 1 laおよび止着部材 12が落下してしまうようなこ とを、防止することができる。  According to this configuration, even if the torsion body constituting member 21 is melted due to an excessive temperature rise during a fire or the like, it is possible to prevent the seat portion constituting member 1 la and the fastening member 12 from falling. can do.
[0048] また、上記構成の卷取体 20は、その下方側に開閉体幅方向へわたって所定間隔 置きに配置された複数の支持部材 30によって、回動自在に受けられており、軸方向 端部側に設けられた駆動源 25 (例えば電動モータやエアーモータ、手動回転機構 等)によって正逆方向へ回転する。  [0048] Further, the scooping body 20 having the above-described configuration is rotatably received by a plurality of support members 30 disposed at predetermined intervals across the opening / closing body width direction on the lower side thereof, and the axial direction It is rotated in the forward and reverse directions by a drive source 25 (for example, an electric motor, an air motor, a manual rotation mechanism, etc.) provided on the end side.
[0049] 各支持部材 30は、略水平に配置された一対のローラ 31, 32を、ブラケット 33によ つて回動自在に支持してなる。  Each support member 30 is configured to rotatably support a pair of rollers 31 and 32 arranged substantially horizontally by a bracket 33.
この支持部材 30は、開閉体幅方向の両側の卷取体構成部材 21, 21の各々に対 し、卷取体軸方向へわたって所定間隔置きに複数 (図示例によれば三つ)設けられ、 ブラケット 33下方側の不動部位に固定されている。  A plurality of support members 30 (three according to the illustrated example) are provided at predetermined intervals along the shaft axis direction for each of the trim body component members 21 and 21 on both sides in the opening / closing body width direction. The bracket 33 is fixed to a stationary part on the lower side.
前記一対のローラ 31, 32は、その一方のローラ 31の中心と卷取体 20の中心とを結 ぶ仮想直線と、その他方のローラ 32の中心と卷取体 20の中心とを結ぶ仮想直線と の角度 Θ力 略 60度に設定されている。この角度は、前記一対のローラ 31, 32から 卷取体 20が脱落し難くすることができ、且つ各ローラ 31 (又は 32)に作用する荷重を 軽減することができる好適な値である。  The pair of rollers 31 and 32 is a virtual straight line connecting the center of one roller 31 and the center of the scooping body 20 and a virtual straight line connecting the center of the other roller 32 and the center of the scooping body 20. The angle between and Θ force is set to approximately 60 degrees. This angle is a suitable value that can make it difficult for the scraper 20 to fall off the pair of rollers 31 and 32 and reduce the load acting on each roller 31 (or 32).
[0050] なお、図示例では、各支持部材 30を隣り合うシート材 l lal, l lalが重なり合う厚 肉部分 pに対応させて配置することで、可撓性シート部 11と各支持部材 30との接触 安定性を良好にしているが、支持部材 30を前記厚肉部分 p以外の箇所に配置するこ とも可能である。  [0050] In the illustrated example, each of the support members 30 is disposed in correspondence with the thick sheet portion p where the adjacent sheet materials l lal and l lal overlap each other, so that the flexible sheet portion 11 and each of the support members 30 However, it is possible to dispose the support member 30 at a location other than the thick portion p.
[0051] 而して、上記構成の開閉装置 1によれば、開閉体 10の開閉動作中、常に、卷取体 20の卷取体構成部材 21と支持部材 30の各ローラ 31 (又は 32)との間に、弹性シ一 ト 40が介在されることになる。 そのため、卷取体構成部材 21の中心線と各ローラ 31 (又は 32)の中心線とが厳密 に平行でない場合であっても、卷取体構成部材 21と各ローラ 31 (又は 32)と間に作 用する面圧(単位面積あたりの荷重)を、弾性シート 40の弾性によって略均一にする ことができる。 Thus, according to the opening / closing device 1 configured as described above, during the opening / closing operation of the opening / closing body 10, the roller body component member 21 of the blade body 20 and each roller 31 (or 32) of the support member 30 are always provided. In between, the fertility sheet 40 is interposed. Therefore, even if the center line of the scraper constituting member 21 and the center line of each roller 31 (or 32) are not strictly parallel, the clearance between the scraper constituting member 21 and each roller 31 (or 32) is not. The surface pressure (load per unit area) applied to the sheet can be made substantially uniform by the elasticity of the elastic sheet 40.
すなわち、図 3に示すように、開閉体 10に巻かれた可撓性シート部 11の外周面と、 各ローラ 31 (又は 32)との接触部分 qにおいて、その接触による面圧(単位面積あた りの荷重)力 弾性シート 40の弾性によって均等化される。  That is, as shown in FIG. 3, at the contact portion q between the outer peripheral surface of the flexible sheet 11 wound around the opening / closing body 10 and each roller 31 (or 32), the surface pressure (unit area Load) force is equalized by the elasticity of the elastic sheet 40.
[0052] 更に、一方のローラ 31の回転中心と他方のローラ 32の回転中心との間の距離を略 二等分する中心線の真上に卷取体 20の回転中心が完全に一致しな 、場合であつ ても、ある程度であれば、その不一致により何れかのローラ 31 (又は 32)に荷重が偏 つてしまうのを、弾性シート 40の弾性によって防ぐことができる。  [0052] Further, the rotation center of the grind body 20 does not completely coincide with the center line that bisects the distance between the rotation center of one roller 31 and the rotation center of the other roller 32. Even in this case, the elasticity of the elastic sheet 40 can prevent the load from being biased to any of the rollers 31 (or 32) due to the mismatch to some extent.
[0053] その上、開閉体幅方向へ並ぶ複数の支持部材 30の高さ寸法が不均一である場合 にも、ある程度であれば、その不均一によって複数の支持部材 30の内の何れかに卷 取体 20の荷重が偏ってしまうのを、弾性シート 40の弾性によって防ぐことができる。  [0053] In addition, even when the height dimensions of the plurality of support members 30 arranged in the width direction of the opening / closing body are non-uniform, to some extent, the non-uniformity causes any one of the plurality of support members 30 to exist.荷重 It is possible to prevent the load of the collector 20 from being biased by the elasticity of the elastic sheet 40.
[0054] なお、上記実施の形態によれば、支持部材 30に対応する箇所に部分的に弾性シ ート 40を設けることで、卷取体 20に巻かれた可撓性シート部 11の外周面を部分的 に拡径させ、該拡径部分と各ローラ 31 (又は 32)との接触安定性を向上するようにし ているが、弾性シート 40を複数の支持部材 30にわたつて設けた態様、弾性シート 40 を開閉体 10の幅方向の略全長に設けた態様、弾性シート 40を開閉体 10の幅方向 および開閉方向へわたる略全面に設けた態様等とすることも可能である。  [0054] According to the above-described embodiment, the outer periphery of the flexible sheet portion 11 wound around the scraper 20 is provided by providing the elastic sheet 40 partially at a location corresponding to the support member 30. The surface is partially expanded to improve the contact stability between the expanded portion and each of the rollers 31 (or 32), but the elastic sheet 40 is provided across the plurality of support members 30. An embodiment in which the elastic sheet 40 is provided over substantially the entire length in the width direction of the opening / closing body 10 and an aspect in which the elastic sheet 40 is provided over substantially the entire surface in the width direction and the opening / closing direction of the opening / closing body 10 are also possible.
[0055] また、上記実施の形態によれば、弾性シート 40の上端側を卷取体 20の外周面に 止着した簡素な止着構造としているが、弾性シート 40の全体を卷取体 20の外周面ま たは可撓性シート部 11に固定した構造としてもょ 、。  [0055] According to the above embodiment, the elastic sheet 40 has a simple fastening structure in which the upper end side of the elastic sheet 40 is fastened to the outer peripheral surface of the scooping body 20. Also, the structure fixed to the outer peripheral surface of the sheet or the flexible sheet part 11.
[0056] また、上記実施の形態によれば、卷取体 20や該卷取体 20に巻き取られた開閉体 1 0を一対のローラ 31, 32からなる支持部材 30によって受けるようにしている力 この 支持部材 30を、卷取体 20や該卷取体 20に巻き取られた開閉体 10を下方側力ゝら受 けて滑らせて回動させる支持部材(図示せず)に置換することも可能である。  [0056] Further, according to the embodiment, the scooping body 20 and the opening / closing body 10 wound around the scooping body 20 are received by the support member 30 including the pair of rollers 31, 32. Force The support member 30 is replaced with a support member (not shown) that slides and rotates the take-up body 20 and the opening / closing body 10 wound around the take-up body 20 by receiving the downward force. It is also possible.
[0057] また、上記実施の形態によれば、開閉体 10の閉鎖方向端部を当接対象部位 yに接 触させた閉鎖状態で、弾性シート 40が卷取体 20に巻かれている構成としたが、他例 としては、開閉体 10が卷取体 20から繰り出された状態において、弾性シート 40も卷 取体 20から繰り出された状態にあり、開閉体 10が卷取体 20に巻かれるのに伴って 卷取体 20の周囲に卷かれる構成としてもよ!/、。 [0057] According to the above embodiment, the closing direction end of the opening / closing body 10 is in contact with the contact target site y. In the closed state, the elastic sheet 40 is wound around the grinder 20, but as another example, when the opening / closing body 10 is extended from the grinder 20, the elastic sheet 40 is also It may be configured so that it is in a state of being drawn out from the body 20 and is wound around the body 20 as the opening / closing body 10 is wound around the body 20! /.
この構成において、弾性シート 40は、開閉体 10に部分的又は全体的に止着されて いてもよいし、該弹性シート 40の開閉体開放方向側の端部が、開閉体 10又は卷取 体 20に止着されていてもよいし、あるいは、該弹性シート 40の開閉体開放方向側の 端部力 卷取体 20に余卷きされた開閉体 10の内周面と卷取体 20の外周面との間に 挟まれることで保持されて 、てもよ!/、。  In this configuration, the elastic sheet 40 may be partially or entirely fixed to the opening / closing body 10, and the end of the coasting sheet 40 on the opening / closing body opening direction side is the opening / closing body 10 or the lid body. Or the end force of the coasting sheet 40 on the opening / closing body opening direction side of the opening / closing body 10 and the inner peripheral surface of the opening / closing body 10 surmounted by the cutting body 20 It is held by being sandwiched between the outer peripheral surface!
なお、図 1は、上述したように上記実施の形態の構成を明瞭に示すために各弾性シ ート 40を開閉体閉鎖方向へ引き出した状態で図示したものであるが、同図 1は、前 記のように、開閉体 10が卷取体 20に巻かれるのに伴って卷取体の周囲に巻かれる 態様も示している。  Note that FIG. 1 shows the elastic sheets 40 pulled out in the closing direction of the opening / closing body in order to clearly show the configuration of the embodiment as described above. As described above, an aspect in which the opening / closing body 10 is wound around the scooping body 20 as it is wound around the scooping body 20 is also shown.
[0058] また、上記実施の形態によれば、弾性シート 40を卷取体 20側に具備した構成とし ているが、この弾性シート 40を省くとともに、図 4に示すように、弾性シート 40'を支持 部材 30,の各ローラ 31 (又は 32)の外周面に固定するようにしてもよ!、。  [0058] According to the embodiment, the elastic sheet 40 is provided on the side of the scooping body 20, but the elastic sheet 40 is omitted and the elastic sheet 40 'is removed as shown in FIG. May be fixed to the outer peripheral surface of each roller 31 (or 32) of the support member 30!
この構成について詳細に説明すれば、支持部材 30'は、上述した支持部材 30と略 同様に構成された各ローラ 31 (又は 32)の外周面に、弾性シート 40'を略一周巻き 付けて接着することで構成されて 、る。  Explaining this configuration in detail, the support member 30 ′ is bonded by winding the elastic sheet 40 ′ around the outer peripheral surface of each roller 31 (or 32) configured substantially the same as the support member 30 described above. It is made up of.
各弾性シート 40'は、上述した弾性シート 40と略同様に、弾性を有する材料から略 帯状に形成されたものである。  Each elastic sheet 40 ′ is formed in a substantially strip shape from a material having elasticity, in substantially the same manner as the elastic sheet 40 described above.
この支持部材 30'を用いた開閉装置によれば、上述した開閉装置 1と略同様の作 用効果を得ることができる上、各支持部材 30'が露出される構成であるため、メンテ ナンス性も良好である。  According to the opening / closing device using the support member 30 ′, it is possible to obtain substantially the same operation effect as the above-described opening / closing device 1, and since each support member 30 ′ is exposed, the maintenance property is improved. Is also good.
[0059] なお、他の好ましい態様としては、上記支持部材 30を構成する複数のローラ 31, 3 2の内、前記開閉体 10における前記卷取体 20から繰出される部分に最も近いローラ 31の外周部接点位置を、該ローラ 31に隣り合うローラ 32の外周部接点位置よりも高 く配設してもよい(図示せず)。 この態様によれば、外周部接点位置が高く配設されたローラ 31によって、卷取体 2 0が開閉体繰出し側へ脱落してしまうようなことを、防止することができる。 As another preferred embodiment, among the plurality of rollers 31 and 32 constituting the support member 30, the roller 31 closest to the portion of the opening / closing body 10 that is fed from the scraping body 20 is used. The outer peripheral contact position may be arranged higher than the outer peripheral contact position of the roller 32 adjacent to the roller 31 (not shown). According to this aspect, it is possible to prevent the scooping body 20 from falling off to the opening / closing body feeding side by the roller 31 provided with a high outer peripheral contact point position.
更には、卷取体 20及び該卷取体 20に巻かれた開閉体 10の荷重方向力 開閉体 繰出し側へ傾いたとしても、その開閉体繰出し側力ゝら卷取体 20を受ける構造である ため、卷取体 20の荷重を複数のローラ 31, 32に対し略均等に分散することができる したがって、一部のローラ 31 (又は 32)から受ける押圧力によって開閉体 10が損傷 したり、一部のローラ 31 (又は 32)の耐久性が低下してしまったり等するのを、し難く することができる。  Furthermore, even if the load body force of the lever body 20 and the opening / closing body 10 wound around the blade body 20 is tilted to the opening / closing body feeding side, the opening body 20 receives the cutting body 20 from the opening / closing body feeding side force. Therefore, it is possible to disperse the load of the trimming body 20 to the plurality of rollers 31, 32 substantially evenly. Therefore, the opening / closing body 10 may be damaged by the pressing force received from some of the rollers 31 (or 32), It is possible to make it difficult to reduce the durability of some rollers 31 (or 32).
[0060] また、他の好ま 、態様として、上記ブラケット 33は弾性体を介在して不動部材に 固定されて 、るようにしてもょ 、。  [0060] As another preferred embodiment, the bracket 33 may be fixed to an immovable member via an elastic body.
この態様によれば、複数のローラ 31, 32の位置が弾性体により矯正されるため、そ れぞれローラ 31, 32が受ける荷重を、より均等化することができる。  According to this aspect, since the positions of the plurality of rollers 31 and 32 are corrected by the elastic body, the loads received by the rollers 31 and 32 can be made more uniform.
[0061] また、上記開閉装置 1に付加する構成として、可撓性シート部 11と支持部材 30との 間に、耐磨耗性シート(図示せず)を設けることで、可撓性シート部が支持部材との摩 擦により損傷してしまうのを防ぐようにしてもょ 、。 [0061] Further, as a configuration added to the opening / closing device 1, a flexible sheet portion is provided by providing an abrasion-resistant sheet (not shown) between the flexible sheet portion 11 and the support member 30. Try to prevent it from being damaged by friction with the support member.
この構成とした場合、前記耐摩耗性シートは、可撓性シート部 11と別体であっても よいが、耐久性等の観点から、好ましくは可撓性シート部 11と一体的に構成される。  In this configuration, the abrasion-resistant sheet may be a separate body from the flexible sheet portion 11, but is preferably configured integrally with the flexible sheet portion 11 from the viewpoint of durability and the like. The
[0062] また、より好ましい態様として、上記可撓性シート部 11が、可撓性を有する繊維材 からなる繊維層と、該繊維層の少なくとも一方の面側に設けられた撥水処理層と、該 撥水処理層の表面に設けられた榭脂コーティング層とからなる構成であってもよい。 この態様によれば、可撓性シート部 11を構成するシート材 1 lalに榭脂コ一ティン グされる際に、榭脂が繊維層に染み込むのを撥水処理槽によって阻む構成としてい るため、繊維層による柔軟性を維持して、可撓性シート部 11の耐久性を向上すること ができる。 [0062] Further, as a more preferable aspect, the flexible sheet portion 11 includes a fiber layer made of a flexible fiber material, and a water-repellent treatment layer provided on at least one surface side of the fiber layer. Further, it may be composed of a resin coating layer provided on the surface of the water repellent treatment layer. According to this aspect, when the resin material is coated on the sheet material 1 lal constituting the flexible sheet portion 11, the water repellent treatment tank prevents the resin from penetrating into the fiber layer. Therefore, the flexibility of the fiber layer can be maintained and the durability of the flexible sheet portion 11 can be improved.
すなわち、上記撥水処理槽を形成せずに、シート材 1 lalに榭脂コーティングした 場合には、繊維層に樹脂が染み込むため、該繊維層の柔軟性が失われて、可撓性 シート部 11が卷取体 20に巻かれた際や風圧を受けた際等の曲げ力によって損傷し てしまうおそれがある。 That is, when the resin material is coated on 1 lal of the sheet material without forming the water-repellent treatment tank, since the resin soaks into the fiber layer, the flexibility of the fiber layer is lost, and the flexible sheet portion 11 is damaged by bending force such as when it is wound around the body 20 or when it receives wind pressure. There is a risk that.
し力しながら、上記構成によれば、繊維層に樹脂が染み込まない状態を維持できる ため、その繊維層の柔軟性によって前記のような可撓性シート部 11の損傷をより効 果的に、し難くすることができる。  However, according to the above configuration, since the state in which the resin does not soak into the fiber layer can be maintained, the damage to the flexible sheet portion 11 as described above is more effectively caused by the flexibility of the fiber layer. Can be difficult.
また、更に好ましい態様として、前記榭脂コーティング層を、少なくとも前記支持部 材 30と接触する側の面に配設すれば、榭脂コーティング層によって、可撓性シート 部 11が支持部材 30との摩擦により磨耗してしまうのを防ぐことができる。  Further, as a more preferable aspect, when the resin coating layer is disposed at least on the surface in contact with the support member 30, the flexible sheet portion 11 and the support member 30 are formed by the resin coating layer. It is possible to prevent wear due to friction.
[0063] (開閉装置 B1)  [0063] (Opening and closing device B1)
次に、開閉体における扉部や該扉部近傍の部分が損傷したり、扉部により支持部 材の耐久性が低下したりするのを防ぐようにした開閉装置 B1につ 、て説明する。  Next, a description will be given of the opening / closing device B1 in which the door portion in the opening / closing body and a portion near the door portion are prevented from being damaged, and the durability of the support member is reduced by the door portion.
[0064] この開閉装置 B1は、可撓性シート部 B11を有する開閉体 B10と、可撓性シート部 B 11の開放方向端部側を外周面に止着した卷取体 B20と、該開閉体 B10をその幅方 向の両端部で開閉方向へ案内するガイドレール(図示せず)とを具備し、開閉体 B10 を卷取体 B20により巻き取ったり繰り出したりするように構成してある。  [0064] This opening / closing device B1 includes an opening / closing body B10 having a flexible sheet portion B11, a scraping body B20 in which the opening direction end of the flexible sheet portion B11 is fixed to the outer peripheral surface, and the opening / closing device Guide rails (not shown) for guiding the body B10 in the opening / closing direction at both ends in the width direction are provided, and the opening / closing body B10 is configured to be wound or unwound by the catching body B20.
[0065] 開閉体 B10は、該開閉体 B10の略全域を構成している可撓性シート部 B11と、該 可撓性シート部 B11の開閉体開放方向側の端部に設けられた止着部材 B12 (図 6参 照)と、該可撓性シート部 B11の開閉体閉鎖方向側の端部に設けられた座板部材 B 15とを備えている。  [0065] The opening / closing body B10 includes a flexible sheet B11 constituting substantially the entire area of the opening / closing body B10, and a fastening provided at an end of the flexible sheet B11 on the opening / closing body opening direction side. A member B12 (see FIG. 6) and a seat plate member B15 provided at the end of the flexible sheet portion B11 on the opening / closing body closing direction side are provided.
[0066] 可撓性シート部 B11は、上述した開閉装置 1における可撓性シート部 11の複数の シート部構成部材 11aおよび止着部材 12と略同様の構成によって、複数のシート部 構成部材 Bl la, Bl lbおよび止着部材 B12を備え、隣り合うシート部構成部材 B11 a, Bl lb間を着脱可能な止着手段 B13によって接続するとともに、その接続箇所に ぉ ヽて開閉体幅方向の橈みを形成して 、る。  [0066] The flexible sheet portion B11 includes a plurality of sheet portion constituting members Bl by substantially the same configuration as the plurality of sheet portion constituting members 11a and the fastening members 12 of the flexible sheet portion 11 in the opening / closing device 1 described above. la, Bl lb, and fastening member B12. Adjacent seat part B11 a and Bl lb are connected by detachable fastening means B13. Forming
[0067] また、複数(図示例によれば三つ)のシート部構成部材 Bl la, Bl lb, 11aの内の 何れかのシート部構成部材には、貫通状の通過口 Bl lb 1、および該通過口 Bl lb 1 を開閉可能に閉鎖する扉部 B16が、シート部構成部材 Bl lbと一体的に具備されて いる。  [0067] Further, any one of the plurality (three in the illustrated example) of the sheet portion constituent members Blla, Bllb, 11a includes a penetrating passage opening Bllb1, and A door part B16 for closing the passage opening Bl lb 1 so as to be openable and closable is provided integrally with the seat part constituting member Bl lb.
なお、これら通過口 Bl lblおよび扉部 B16は、図示例によれば、開閉体幅方向の 中央側のシート部構成部材 Bl lbに設けるようにして 、るが、両側のシート部構成部 材 Bl la, Bl laの内の一方に設けるようにしてもよいし、可撓性シート部 B11に対し 複数設けるようにしてもよい。 According to the illustrated example, the passage opening Bl lbl and the door portion B16 are arranged in the opening / closing body width direction. However, it may be provided on one of the sheet component parts Bl la, Bl la on both sides, or on the flexible sheet part B11. A plurality of them may be provided.
[0068] 通過口 Bl lblは、人や物等を通過可能な開口部であり、図示例によれば正面視 略矩形状に形成されている。 [0068] The passage opening Bl lbl is an opening through which a person or an object can pass, and is formed in a substantially rectangular shape in front view according to the illustrated example.
この通過口 Bl lblは、正面視三角形状や、円形状、切り込み (スリット)、その他の 形状とすることも可能である。  The passage opening Bl lbl can also have a triangular shape in front view, a circular shape, a notch (slit), or other shapes.
[0069] 扉部 B16は、上記シート部構成部材 Bl la, Bl lbと同様の難燃性の可撓性シート 材からなり、図示例によれば正面視略矩形状に形成される。 [0069] The door portion B16 is made of a flame-retardant flexible sheet material similar to the above-mentioned seat portion constituent members Blla, Bllb, and is formed in a substantially rectangular shape in front view according to the illustrated example.
この扉部 B16は、その周縁をシート部構成部材 Bl lbにおける前記通過口 Bl lbl の周囲部分に重ね合わせることで、開閉体 B10の厚肉部を構成しており、その上辺 部がシート部構成部材 Bl lbに止着されることで、自重により垂れ下がって、通過口 B l lblを閉鎖しいる。  The door B16 has a thick wall portion of the opening / closing body B10 by superimposing a peripheral edge of the door portion B16 on a peripheral portion of the passage opening Bl lbl in the seat portion constituent member Bl lb, and an upper side portion of the door portion B16 is configured as a seat portion. By being fixed to the member Bl lb, it hangs down by its own weight and closes the passage opening B l lbl.
したがって、この扉部 B16を開放する際には、該扉部 B16の下端側を捲り上げたり 、該扉部 B16の側部を捲ったり等すればょ 、。  Therefore, when opening the door portion B16, the lower end side of the door portion B16 is lifted up or the side portion of the door portion B16 is turned up.
なお、この扉部 B16は、シート部構成部材 Bl lbの一方の面に配設された態様とし てもよいし、シート部構成部材 Bl lbの両方の面に配設された態様としてもよいが、開 閉体 B10による閉鎖性を良好にするためには、後者の態様とするのが好ましい。  The door portion B16 may be disposed on one surface of the seat member constituting member Bl lb, or may be disposed on both surfaces of the seat member constituting member Bl lb. In order to improve the closing performance of the open / close body B10, the latter embodiment is preferable.
[0070] そして、隣り合うシート部構成部材 Bl la, Bl lbは、その幅方向の端部側同士が重 ね合わせられ、その重なり合い部分 Bl lalを、開閉体幅方向の張力を逃がすように 開閉体幅方向に橈みを有する状態で、止着手段 B13によって止着している。 [0070] Then, the adjacent sheet portion constituent members Bl la and Bl lb are overlapped at the end portions in the width direction, and the overlapping portions Bl lal are opened and closed so as to release the tension in the opening and closing body width direction. It is fastened by fastening means B13 in a state of having itch in the body width direction.
前記重なり合い部分 Bl lalは、隣り合う卷取体構成部材 B21, B21の間の空間部 分に入り込むように、適度に橈ませてある。  The overlapping portion Bl lal is moderately curled so as to enter the space portion between the adjacent trimming member constituting members B21, B21.
この構成によれば、風圧や振動等に起因して、可撓性シート部 B11に開閉体幅方 向の張力が作用したとしても、その張力を、前記重なり合い部分 Bl lalの橈みによつ て緩和することができ、ひ 、ては可撓性シート部 Bl 1の損傷等を防ぐことができる。  According to this configuration, even if a tension in the width direction of the opening / closing body acts on the flexible sheet B11 due to wind pressure, vibration, etc., the tension is applied by the stagnation of the overlapping portion Bl lal. Can be alleviated, and damage to the flexible sheet portion Bl1 can be prevented.
[0071] また、止着手段 B13は、例えば、凹状部材と凸状部材とを嵌め合わせるようにした 所謂スナップや、ボタン体をボタン孔に通して係止するようにした所謂ボタン等の構 成とすることができる。 [0071] The fixing means B13 is, for example, a structure such as a so-called snap that fits the concave member and the convex member, or a so-called button that locks the button body through the button hole. Can be made.
止着手段 B13を前記スナップとした場合には、隣り合うシート部構成部材 Bl la, B 11aを接続する際の作業性が良好であり、また、開閉体 B10を閉鎖した際の閉鎖遮 蔽性を有効に確保することができる。しかも、接続された状態の前記凹状部材と前記 凸状部材とを比較的容易に外すことができるため、例えば、非常時等に、開閉体 B1 0が閉鎖状態であっても、凹状部材と凸状部材とを外して避難用等の開口部を容易 に形成することができ、また、突風等により可撓性シート部に強大な張力が発生した 際等には、その際の張力により凹状部材と凸状部材とが外れるため、可撓性シート部 B11の損傷を防ぐことができる。  When the fastening means B13 is the snap, the workability when connecting the adjacent seat part constituent members Bla, B 11a is good, and the closing shielding property when the opening / closing body B10 is closed Can be effectively secured. In addition, since the concave member and the convex member in a connected state can be removed relatively easily, for example, in the event of an emergency, even when the opening / closing body B10 is in a closed state, the concave member and the convex member may be removed. It is possible to easily form an opening for evacuation by removing the shaped member, and when a strong tension is generated in the flexible sheet due to a gust of wind, etc., the recessed member is caused by the tension at that time. And the convex member come off, so that damage to the flexible sheet portion B11 can be prevented.
また、止着手段 B13を前記ボタンとした場合には、前記ボタン体の開閉体幅方向へ 移動をボタン孔の変形によってある程度許容できるため、可撓性シート部 Bl 1に作 用する開閉体幅方向の張力を緩和することができる。  Further, when the fastening means B13 is the button, since the movement of the button body in the opening / closing body width direction can be allowed to some extent by deformation of the button hole, the opening / closing body width acting on the flexible sheet portion Bl 1 Directional tension can be relaxed.
なお、止着手段 B13の他例としては、面ファスナーやスライドファスナー、ボルトとナ ット、磁石、ステーブル、その他の係脱部材とすることも可能である。  As other examples of the fastening means B13, a hook-and-loop fastener, a slide fastener, a bolt and nut, a magnet, a stable, and other engaging / disengaging members may be used.
[0072] また、図示例の止着手段 B13は、隣り合うシート部構成部材 Bl la, Bl laの端部同 士の重ね合わせ部分に、開閉体開閉方向へわたって複数設けられるとともに、開閉 体幅方向へわたっても複数設けられている。 [0072] In addition, a plurality of fixing means B13 in the illustrated example are provided in the overlapping portion of the end portions of the adjacent sheet portion constituent members Blla and Blla in the opening / closing body opening / closing direction, and the opening / closing body A plurality are provided even in the width direction.
この構成によれば、隣り合うシート部構成部材 Bl la, Bl laの重ね合わせ部分に おける一方のシート部構成部材 Bl laが、風圧等の影響により捲れてしまうのを防ぐ ことができ、ひいては、前記捲れに起因して、可撓性シート部 B11が卷取体 B20に卷 かれた際の卷径が大きくなつたり、接続箇所が容易に外れてしまったり等するようなこ とを、防ぐことができる。  According to this configuration, it is possible to prevent one of the sheet part constituent members Bl la in the overlapping portion of the adjacent sheet part constituent members Bl la and Bl la from being drowned by the influence of wind pressure or the like. To prevent the flexible sheet portion B11 from becoming large when the flexible sheet portion B11 is wound on the grind body B20 or the connecting portion from being easily detached due to the above-mentioned curling. it can.
[0073] また、卷取体 B20は、上記開閉装置 1における卷取体 20と略同様の構造によって 、凹部 B21aを有する卷取体構成部材 B21、中子 B23、軸部材 B22、止着部材 B12 等を具備し、支持部材 B24, B24'によって回動自在に受けられ、駆動源 B25によつ て正逆方向へ回転する。  [0073] Further, the catching body B20 has a structure substantially the same as the catching body 20 in the switchgear 1 described above, and the catching body constituting member B21 having the recess B21a, the core B23, the shaft member B22, and the fastening member B12. , Etc., and is rotatably received by the support members B24 and B24 ′ and rotated in the forward and reverse directions by the drive source B25.
[0074] 各支持部材 B24は、略水平に配置された一対のローラ B24a, B24bを、ブラケット B24cによって回動自在に支持してなる。 この支持部材 B24は、開閉体幅方向の両側の卷取体構成部材 B21, B21につい て、その各々に対し、卷取体軸方向へわたって所定間隔置きに複数(図示例によれ ば三つ)設けられている。 [0074] Each support member B24 is configured to rotatably support a pair of rollers B24a and B24b arranged substantially horizontally by a bracket B24c. The support member B24 includes a plurality of support structure members B21 and B21 on both sides in the width direction of the opening / closing body. ) Is provided.
前記一対のローラ B24a, B24bは、その一方のローラ B24aの中心と卷取体 B20の 中心とを結ぶ仮想直線と、その他方のローラ B24bの中心と卷取体 B20の中心とを結 ぶ仮想直線との角度 B θ 1が、適宜に設定されている。  The pair of rollers B24a, B24b is an imaginary straight line connecting the center of one roller B24a and the center of the scooping body B20 and a virtual straight line connecting the center of the other roller B24b and the center of the scooping body B20. The angle B θ1 is set appropriately.
[0075] 同様にして、各支持部材 B24'は、略水平に配置された一対のローラ B24a' , B24 b'を、ブラケット B24c'によって回動自在に支持してなる。 Similarly, each support member B24 ′ is configured to rotatably support a pair of rollers B24a ′ and B24 b ′ arranged substantially horizontally by a bracket B24c ′.
この支持部材 B24'は、開閉体幅方向の中央側の卷取体構成部材 B21に対し、卷 取体軸方向へわたって所定間隔置きに複数(図示例によれば二つ)設けられて 、る この支持部材 B24'の配置について詳細に説明すれば、この支持部材 B24'は、 卷取体 B20に開閉体 B10の可撓性シート部 Bl 1が巻き取られた際に、通過口 Bl lb 1及び扉部 B16を開閉体幅方向へ避けるように、これら通過口 Bl lbl及び扉部 B16 の両側に配置されている。  A plurality of support members B24 ′ (two according to the illustrated example) are provided at predetermined intervals over the grip body axial direction of the grip body constituting member B21 on the center side in the opening / closing body width direction. The arrangement of the support member B24 ′ will be described in detail. The support member B24 ′ has a passage opening Bl lb when the flexible sheet portion Bl 1 of the opening / closing body B10 is wound around the scooping body B20. 1 and the door part B16 are arranged on both sides of the passage opening Bl lbl and the door part B16 so as to avoid the opening / closing body width direction.
そして、前記一対のローラ B24a', B24b'のローラ間隔は、他の支持部材 B24を 構成する一対のローラ B24a, B24bにおけるローラ間隔よりも狭く設定されている。 換言すれば、前記一対のローラ B24a,, B24b,は、その一方のローラ B24a,の中 心と卷取体 B20の中心とを結ぶ仮想直線と、その他方のローラ B24b'の中心と卷取 体 B20の中心とを結ぶ仮想直線との角度 B Θ 2が、上記支持部材 B24における角度 B 0 1よりも小さくなるように配置されている。  The roller interval between the pair of rollers B24a ′ and B24b ′ is set to be narrower than the roller interval between the pair of rollers B24a and B24b constituting the other support member B24. In other words, the pair of rollers B24a, B24b is composed of an imaginary straight line connecting the center of one of the rollers B24a and the center of the scooping body B20 and the center of the other roller B24b 'and the scooping body. The angle B Θ 2 with the imaginary straight line connecting the center of B20 is arranged to be smaller than the angle B 0 1 in the support member B24.
例えば、前記角度 B θ 1は角度 60度とされ、前記角度 B Θ 2は角度 60度よりも小さ い値に設定される。  For example, the angle Bθ1 is set to an angle of 60 degrees, and the angle BΘ2 is set to a value smaller than the angle of 60 degrees.
[0076] 上述したローラ B24a, B24b, B24a' , B24b,の配置によれば、一対のローラ B24 a' , B24b'が卷取体構成部材 B21から受ける荷重を、一対の一対のローラ B24a, B 24bが卷取体構成部材 B21から受ける荷重よりも小さくすることができる。  [0076] According to the arrangement of the rollers B24a, B24b, B24a ', B24b described above, the pair of rollers B24a, B24 receives the load that the pair of rollers B24a', B24b 'receives from the scraper constituting member B21. It is possible to make the load 24b smaller than the load that is received from the harvester constituting member B21.
[0077] この作用について詳細に説明すれば、図 8 (a) (b)に示すように、ローラ間隔が比較 的広い一対のローラ B24a, B24bと、ローラ間隔が比較的狭い一対のローラ B24a, , B24b'とでは、卷取体構成部材 B21から受ける荷重が異なってくる。 すなわち、図 8 (a) (b)において、卷取体構成部材 B21の重量は双方とも略同じで あり、同じ長さの下方向きのベクトル BVで表すことができる。 Explaining this operation in detail, as shown in FIGS. 8 (a) and 8 (b), a pair of rollers B24a, B24b having a relatively large roller interval and a pair of rollers B24a, having a relatively small roller interval, , B24b ′ has different loads received from the trimming body component B21. That is, in FIGS. 8 (a) and 8 (b), the weight of the trimming member constituting member B21 is substantially the same, and can be expressed by a downward vector BV having the same length.
そして、図 8 (a)においては、一対のローラ B24a, B24b力 卷取体構成部材 B21 力 受ける荷重は、ベクトル BVの分力であり、それぞれベクトル Bvl, Bvlとして表す ことができる。  In FIG. 8 (a), the pair of rollers B24a and B24b forces, the gripping member constituting member B21, and the received loads are the component forces of the vector BV, and can be expressed as vectors Bvl and Bvl, respectively.
同様に、図 8 (b)においては、図 8 (a)においては、一対のローラ B24a', B24b'が 、卷取体構成部材 B21から受ける荷重は、ベクトル BVの分力であり、それぞれべタト ノレ Bv2, Bv2として表すこと力 Sでさる。  Similarly, in FIG. 8 (b), in FIG. 8 (a), the load received by the pair of rollers B24a 'and B24b' from the scraper constituting member B21 is a component force of the vector BV. Tatonore Bv2, expressed as Bv2, with force S.
前記ベクトル Bvlとベクトル Bv2とを比較すると、ベクトル Bvl, Bvl間の角度 B 0 1 よりも、ベクトル Bv2, Bv2間の角度 B Θ 2の方が小さいため、ベクトル Bv2の方がベタ トル Bvlよりも短くなる。  Comparing the vector Bvl and the vector Bv2, the angle B Θ2 between the vectors Bv2 and Bv2 is smaller than the angle B 01 between the vectors Bvl and Bvl, so the vector Bv2 is more than the vector Bvl. Shorter.
[0078] したがって、ローラ間隔が狭い一対のローラ B24a', B24b'の方力 ローラ間隔の 広い一対のローラ B24a, B24bよりも、各ローラが受ける荷重が小さくなる。  Accordingly, the direction force of the pair of rollers B24a ′ and B24b ′ having a narrow roller interval The load received by each roller is smaller than that of the pair of rollers B24a and B24b having a large roller interval.
本願発明者は、一対のローラ B24a, B24b間の角度 B 0 1を角度 60度とした場合 を基準にして、その角度を約 50度とした場合には、各ローラ B24aが受ける荷重を約 4. 4%軽減でき、更に、その角度を約 40度とした場合には、各ローラ B24aが受ける 荷重を約 7. 8%軽減できることを実験的に確認している。  The inventor of the present application refers to the case where the angle B01 between the pair of rollers B24a and B24b is 60 degrees, and when the angle is about 50 degrees, the load received by each roller B24a is about 4 It has been experimentally confirmed that the load applied to each roller B24a can be reduced by about 7.8% when the angle can be reduced by about 40% and when the angle is about 40 degrees.
なお、図 8によれば、上記作用を明瞭に示すために、ローラ B24a, B24bのローラ 間隔を実際よりも広く図示し、ローラ B24a', B24b'のローラ間隔を実際よりも狭く図 示している。  Note that, according to FIG. 8, in order to clearly show the above-described operation, the roller interval between the rollers B24a and B24b is shown wider than the actual one, and the roller interval between the rollers B24a 'and B24b' is shown smaller than the actual one. .
[0079] 而して、上記開閉装置 B1によれば、支持部材が通過口 Bl lbl及び扉部 B16を避 けた位置に配置されているため、可撓性シート部 B11を卷取体 B20に巻き取った際 に、可撓性シート部 B11が通過口 Bl lbl及び扉部 B16に対応する位置で卷太りし、 その卷太り部分が支持部材 B24によって比較的強く押圧されてしまうのを防ぐことが できる。  [0079] Thus, according to the opening / closing device B1, the support member is disposed at a position avoiding the passage port Blbl and the door portion B16, and therefore the flexible sheet portion B11 is wound around the scraper B20. When removing, it is possible to prevent the flexible sheet portion B11 from thickening at a position corresponding to the passage opening Blbl and the door portion B16, and the thickened portion from being pressed relatively strongly by the support member B24. it can.
[0080] また、上記構成によれば、通過口 Bl lbl及び扉部 B16に対応する卷取体構成部 材 B21 (図 5における中央側の卷取体構成部材 B21)を受ける支持部材 B24'の数 力 他の卷取体構成部材 B21を受ける支持部材 B24の数よりも少なくなる力 上述し たように一対のローラ B24a', B24b'のローラ間隔を適宜に設定することで、各支持 部材 B24a'が卷取体構成部材 B21から受ける荷重を軽減している。 [0080] Further, according to the above-described configuration, the support member B24 'that receives the cut-out member constituting member B21 (the cut-out member forming member B21 on the center side in Fig. 5) corresponding to the passage port Bl lbl and the door portion B16. number Force Force that is smaller than the number of the support members B24 that receive the other trimming member constituting member B21 As described above, each support member B24a ′ can be set by appropriately setting the roller spacing between the pair of rollers B24a ′ and B24b ′. Reduces the load received from the body component B21.
したがって、開閉体幅方向へ配置された複数の支持部材 B24, B24'が卷取体 B2 0から受ける荷重を均等化することができ、支持部材 B24'の箇所で、部分的にシート 部構成部材 Bl lbが破損したり支持部材 B24'の耐久性が低下したり等するのを防ぐ ことができる。  Therefore, it is possible to equalize the load received by the plurality of support members B24, B24 'arranged in the width direction of the opening / closing body from the trimming body B20, and at the position of the support member B24', the seat part constituent member partially It is possible to prevent the Bl lb from being damaged or the durability of the support member B24 'from being lowered.
[0081] なお、図 5に示す開閉装置 B1では、連結された複数の卷取体構成部材 B21の外 径を略同一にしている力 他の好ましい態様としては、扉部 B16と通過口 Bl lblの 周囲部分とが重ね合わせられた厚肉部に対応するように、図示における中央の卷取 体構成部材 B21を全体的または部分的に縮径してもよい。  [0081] In addition, in the opening / closing device B1 shown in FIG. 5, the force that makes the outer diameters of the plurality of connecting body constituting members B21 substantially the same as other preferred embodiments is that the door B16 and the passage port Bl lbl In the figure, the central scraper constituting member B21 in the figure may be reduced in diameter entirely or partially so as to correspond to the thick portion where the peripheral portion is overlapped.
この構成によれば、開閉体 B10を卷取体 B20に巻き取った際に、巻き取られた開 閉体 B 10における前記厚肉部に対応する部位が、他の部位よりも巻き太りしてしまう 度合 、を低減することができる。  According to this configuration, when the opening / closing body B10 is wound around the winding body B20, the portion corresponding to the thick portion in the wound opening / closing body B10 is thicker than the other portions. It is possible to reduce the degree of erosion.
[0082] また、図 5に例示する開閉装置 B1では通過口 Bl lblおよび扉部 B16を単数設け るようにした力 他例としては、通過口 Bl lblおよび扉部 B16を開閉体幅方向へ複 数配設してもよい。 [0082] In addition, in the opening / closing device B1 illustrated in FIG. 5, the force in which a single passage port Bl lbl and a door portion B16 are provided. As another example, the passage port Bl lbl and the door portion B16 are combined in the opening / closing body width direction. You may arrange several.

[0092] 而して、図 9及び図 10に示す開閉装置 D3によれば、卷取体 D20'の周囲に開閉 体 D10'が巻かれ、開閉体幅方向において偏った巻き太り箇所が生じた場合でも、 長孔 D21d'の箇所で、止着具 D14が卷取体構成部材 D21 'に対し開閉体幅方向 へ若干移動、すなわち卷取体構成部材 D21 'に対し中子 D23'が部分的に開閉体 幅方向へ若干移動するため、隣り合う卷取体構成部材 D21 ' , D21 '間が折れ曲が るようにして柔軟に変形する。 Thus, according to the opening / closing device D3 shown in FIG. 9 and FIG. 10, the opening / closing body D10 ′ is wound around the trimming body D20 ′, resulting in unevenly thickened portions in the width direction of the opening / closing body. Even in the case of the long hole D21d ', the fastening device D14 moves slightly in the opening / closing body width direction with respect to the trimming body component D21', that is, the core D23 'is partially moved relative to the trimming body component D21'. Opening and closing body Since it moves slightly in the width direction, it is deformed flexibly so that the adjacent cut-off body constituting members D21 'and D21' are bent.
そのため、卷取体 D20の下方側において開閉体幅方向へ複数対設けられるローラ D24a, D24bの内、その一部のローラ D24a, D24bに負荷が偏ってしまうのを防ぐ ことができる。  Therefore, it is possible to prevent the load from being biased to a part of the rollers D24a and D24b among the rollers D24a and D24b provided in a plurality of pairs in the opening / closing body width direction on the lower side of the scraper D20.
すなわち、隣り合う卷取体構成部材 D21 ' , D21 '間の柔軟な変形により、卷取体 D 20の荷重力 複数対のローラ D24a, D24bに適宜に分散されるようになる。  In other words, due to the flexible deformation between the adjacent scraper constituting members D21 ′ and D21 ′, the load force of the scraper D20 is appropriately distributed to the plural pairs of rollers D24a and D24b.
その上、卷取体 D20'に開閉体 D10'が巻かれた際、その卷取体 D20'と周囲の開 閉体 D10'との間には弾性シート D25が介在されるため、この弾性シート D25の弾性 により、開閉体 D10'と一対のローラ D24a, D24bとの接触面に加わる押圧力を分散 することができ、ひいては、開閉体 D10'がー対のローラ D24a, D24bとの局部的な 接触により損傷してしまうようなことを、し難くすることができる。  In addition, when the opening / closing body D10 ′ is wound around the clad body D20 ′, an elastic sheet D25 is interposed between the clad body D20 ′ and the surrounding open / close body D10 ′. Due to the elasticity of D25, the pressing force applied to the contact surface between the opening / closing body D10 ′ and the pair of rollers D24a, D24b can be dispersed. As a result, the opening / closing body D10 ′ is locally connected to the pair of rollers D24a, D24b. It can be made difficult to be damaged by contact.
[0093] なお、図 9に示す一例では、丸孔 D21c'を止着具 D14により開閉体 D10'を止着 するための孔とし、長孔 D21d'を止着具 D14により卷取体構成部材 D21 'と中子 D2 3'とを固定するための孔としている力 他例としては、その丸孔 D21c'と長孔 D21d' とを逆に用いた態様とすることも可能である。  [0093] In the example shown in Fig. 9, the round hole D21c 'is used as a hole for fixing the opening / closing body D10' by the fastening tool D14, and the long hole D21d 'is used by the fastening tool D14 as the framing body constituting member. Force used as a hole for fixing D21 ′ and core D2 3 ′ As another example, it is possible to adopt a mode in which the round hole D21c ′ and the long hole D21d ′ are used in reverse.
[0094] なお、図 9に示す一例では、隣り合う卷取体構成部材 D21 ' , D21 '間が適宜に曲 力 Sるように、周方向にお 、て丸孔 D21c 'の数よりも長孔 D21d'の数を多くして 、るが 、他例としては、丸孔 D21c'と長孔 D21d'の数を同数にしたり、丸孔 D21c'の数より も長孔 D21d'の数を少なくすることも可能である。  [0094] In the example shown in Fig. 9, the circumferential length is longer than the number of round holes D21c 'so that the bending member constituting members D21' and D21 'have an appropriate bending force S. However, as another example, the number of round holes D21c 'and the number of long holes D21d' are the same, or the number of long holes D21d 'is smaller than the number of round holes D21c'. It is also possible to do.
[0095] また、図 9及び図 10に示す態様に付加する構成として、開閉体 D10'を止着するた めの丸孔 D21c'の箇所において、卷取体構成部材 D21 'の内周面と中子 D23'の 外周面との間に、卷取体構成部材 D21 'よりも融点の高い金属材料力もなるとともに 隣り合う中子 D23' , D23'間にわたる長尺状の板材(図示せず)を配設し、この板材 および中子 D23'に対し、開閉体 D10'及び卷取体構成部材 D21 'に貫通させた止 着具 D14を止着するようにしてもょ 、。  [0095] Further, as a configuration added to the mode shown in Figs. 9 and 10, the inner peripheral surface of the grind body component member D21 'is arranged at the position of the round hole D21c' for fixing the opening / closing body D10 '. Between the outer peripheral surface of the core D23 ', a metal material force having a melting point higher than that of the trimming member constituting member D21' and a long plate material (not shown) extending between the adjacent cores D23 'and D23' It is also possible to fix the fastening member D14 penetrated through the opening / closing body D10 ′ and the clamp body component D21 ′ to the plate material and the core D23 ′.
この構成によれば、開閉体 D10の止着強度を一層向上するとともに、卷取体構成 部材 D21 'の熱溶融により開閉体 D10が落下するようなことを、より効果的に防止す ることがでさる。 According to this configuration, the fastening strength of the opening / closing body D10 is further improved, and it is more effectively prevented that the opening / closing body D10 falls due to thermal melting of the trimming body component D21 ′. It can be done.
[0096] また、図 9に示す態様によれば、一対のローラ D24a, D24bを開閉体厚さ方向(図 26〜28における左右方向)へ移動不能な構成としている力 一対のローラ D24a, D 24bを、図 11に示す態様のように支持することで、開閉体厚さ方向へ位置調整可能 な構成とすることも可能である。  In addition, according to the embodiment shown in FIG. 9, the pair of rollers D24a, D24b is configured such that the pair of rollers D24a, D24b cannot move in the opening / closing body thickness direction (left-right direction in FIGS. 26 to 28). It is also possible to adopt a configuration in which the position can be adjusted in the opening / closing body thickness direction by supporting as shown in FIG.
図 11に示す一対のローラ D24a, D24bは、ブラケット D24cによって回動自在に支 持されている。  A pair of rollers D24a and D24b shown in FIG. 11 is rotatably supported by a bracket D24c.
ブラケット D24cは、その底面部における開閉体幅方向の両側に、取付け片部 D24 cl, D24clを有する。そして、各取付け片部 D24clには、開閉体厚さ方向へ長い 長孔 D24c 11が形成されて!ヽる。  The bracket D24c has mounting pieces D24cl and D24cl on both sides of the bottom surface of the bracket D24c in the opening / closing body width direction. Each attachment piece D24cl is formed with a long hole D24c 11 which is long in the opening / closing body thickness direction.
このブラケット D24cは、その下方側の不動部位である基材 D26に載置され、前記 長孔 D24cl lに揷通されるネジゃボルト等の止着具 D24cl2によって基材 D26に対 し固定される。  This bracket D24c is mounted on the base material D26, which is an immobile part on the lower side thereof, and is fixed to the base material D26 by a fastening tool D24cl2 such as a screw bolt passed through the long hole D24cll. .
図 11に示す態様によれば、止着具 D24cl2を緩めてブラケット D24c及び一対の ローラ D24a, D24bの位置を開閉体厚さ方向へ調整することができる。  According to the embodiment shown in FIG. 11, the fastening tool D24cl2 can be loosened to adjust the positions of the bracket D24c and the pair of rollers D24a, D24b in the opening / closing body thickness direction.
したがって、卷取体 D20の下方側に開閉体幅方向へ複数対設けられるローラ D24 a, D24bについて、開閉体厚さ方向位置のばらつきに起因して、卷取体 D20の外周 面に接触しないローラ D24a (又は D24b)が発生するようなことを防ぐことができ、ひ いては、各ローラ D24a (又は D24b)と卷取体 D20外周面との接触圧力を均等化す ることがでさる。  Therefore, for the rollers D24a and D24b that are provided in pairs in the opening / closing body width direction on the lower side of the scraper D20, the rollers that do not contact the outer peripheral surface of the scraper D20 due to variations in the position in the opening / closing body thickness direction. The occurrence of D24a (or D24b) can be prevented, and as a result, the contact pressure between each roller D24a (or D24b) and the outer periphery of the scraper D20 can be equalized.
[0097] なお、図 11に示す一例によれば、位置調整した後のブラケット D24cを止着具 D24 cl2によって基材 D26に対し固定する構造としている力 他の好ましい態様としては 、ブラケット D24cを基材 D26に対し開閉体厚さ方向へ移動可能となるように止着し てもよく、この態様によれば、卷取体 D20 (又は D20' )に巻かれた開閉体 D10 (又は D10' )の状態に応じて、ブラケット D24cを開閉体厚さ方向へ微動させることができ、 ひいては、各ローラ D24a (又は D24b)に加わる荷重を一層均等化することができる 図面の簡単な説明 [0098] [図 1]本発明に関わる開閉装置の一例を示す正面図である。 [0097] According to the example shown in Fig. 11, the force is such that the bracket D24c after position adjustment is fixed to the base material D26 by the fastening tool D24 cl2, and as another preferred embodiment, the bracket D24c is used as a base. The opening / closing body D10 (or D10 ′) wound around the scraper D20 (or D20 ′) may be fixed to the material D26 so as to be movable in the opening / closing body thickness direction. The bracket D24c can be finely moved in the opening / closing body thickness direction according to the state of the opening and closing, so that the load applied to each roller D24a (or D24b) can be further equalized.
