つぎに、本発明の実施の形態について、図面に基づいて説明する。
図面において、１はシートシャッター装置のシャッターカーテンに相当するシート体であって、該シート体１は矩形状に裁断されたシート材を適宜縫製、溶着等の加工を施すことにより構成されており、上縁部は、開口部上方に設けたシャッターケース２内に回転自在に軸承される巻き取りドラム３に連結されている。そして、シート体１は、後述するように、左右方向（幅方向）に長い骨材４を開閉方向複数箇所に配設することにより剛性を付与されており、シート体１の左右両側縁部と、骨材４の左右両端部から突出する細軸状の軸部４ａとが、開口部の両側部に配設された一対のガイドレール５のガイド溝５ａにそれぞれ移動自在に嵌挿されている。そして、図示しない開閉機の正逆駆動に伴い、巻き取りドラム３が回転することにより、シート体１の巻き取りドラム３への巻き取り、巻き出しがなされ、これによって、シート体１がガイドレール５内を移動して開口部を開放する全開姿勢と開口部を閉鎖する全閉姿勢とのあいだを開閉移動するように構成されており、これらの基本構成は従来通りの構成となっている。
尚、１ａは、シート体１の下端部を上方に向けて折り返し、該折り返し部をシート体１に一体化することにより形成された袋状部であって、該袋状部１ａには、シート体１の座板としての機能を果すべく錘としての主骨材１ｂが収容されている。 Next, embodiments of the present invention will be described with reference to the drawings.
In the drawings, 1 is a sheet body corresponding to a shutter curtain of a sheet shutter device, and the sheet body 1 is configured by appropriately processing a sheet material cut into a rectangular shape, such as sewing and welding, The upper edge is connected to a take-up drum 3 that is rotatably supported in a shutter case 2 provided above the opening. And the sheet | seat body 1 is provided with rigidity by arrange | positioning the aggregate 4 long in the left-right direction (width direction) in the opening-and-closing direction several places so that it may mention later, The thin shaft-like shaft portions 4a projecting from both the left and right ends of the aggregate 4 are movably fitted in the guide grooves 5a of the pair of guide rails 5 disposed on both sides of the opening. . Then, when the winding drum 3 rotates in accordance with the forward / reverse driving of the opening / closing machine (not shown), the sheet body 1 is wound and unwound on the winding drum 3, whereby the sheet body 1 is guided to the guide rail. 5 is configured to open and close between a fully open posture that moves within 5 and opens the opening, and a fully closed posture that closes the opening, and these basic configurations are the same as conventional ones.
Reference numeral 1a denotes a bag-like portion formed by folding the lower end portion of the sheet body 1 upward and integrating the folded portion with the sheet body 1. The bag-like portion 1a includes a sheet-like portion. A main aggregate 1b as a weight is accommodated so as to perform the function as a seat plate of the body 1.

さて、前記シート体１は、一方の面であって、本実施の形態では屋内側に面する裏面に、前記骨材４を収容するべく開閉方向複数箇所に骨材収容部Ｈが設けられているが、各骨材収容部Ｈに本発明が実施されており、シート体１を構成するシート材と同様のシート材を用いて形成される第一、第二骨材受けシート６、７により構成されている。
尚、骨材収容部Ｈは、シート体１を巻き取りドラム３に巻装したときに、骨材４が周回り方向に位置ズレする位置関係となるよう、巻き取りドラム３への巻き形に対応してシート体１の予め設定される上下方向位置に設けられるように設定されている。 Now, the sheet body 1 is provided with aggregate storage portions H at a plurality of locations in the opening / closing direction so as to store the aggregate 4 on one surface, which is the back surface facing the indoor side in the present embodiment. However, the present invention is implemented in each aggregate housing portion H, and the first and second aggregate receiving sheets 6 and 7 are formed using the same sheet material as the sheet material constituting the sheet body 1. It is configured.
The aggregate housing portion H is wound around the take-up drum 3 so that the aggregate 4 is displaced in the circumferential direction when the sheet body 1 is wound around the take-up drum 3. Correspondingly, the sheet body 1 is set so as to be provided at a preset vertical position.

つぎに、骨材収容部Ｈの詳細について説明する。
まず、第一骨材受けシート６は、骨材４の外周面を包含する包含部６ａと、該包含部６ａの上下縁部であって、第二骨材受けシート７に縫着するための縫着代６ｂとが形成されたものに構成されている。前記第一骨材受けシート６の左右方向幅は、シート体１の左右幅と同様の左右長さに設定され、開閉方向長さ（上下方向長さ）は、骨材４を包含可能な包含部６ａの上下方向長さに縫着代６ｂの上下方向長さの二倍を加えた長さに設定されている。さらに、第一骨材受けシート６は、包含部６ａの左右両端部に位置し、骨材４の軸部４ａに略相当する長さ分を切り落とすことにより切り欠き窓６ｃがそれぞれ形成されている。
一方、第二骨材受けシート７は、第一骨材受けシート６の縫着代６ｂが縫着され、第一骨材受けシート６の包含部６ａとともに骨材４を収容する収容部７ａと、該収容部７ａの上下方向（開閉方向）外方に向けて予め設定される長さ寸法で延出する余長部７ｂとがそれぞれ形成されたものに構成されており、第二骨材受けシート７の左右方向長さは、前記シート体１および第一骨材受けシート６の左右方向長さと同様の長さに設定されており、開閉方向長さ（上下方向長さ）は、収容部７ａの上下方向長さに上下の余長部７ｂの上下方向長さをそれぞれ加えた長さに設定されている。 Next, details of the aggregate housing part H will be described.
First, the first aggregate receiving sheet 6 includes an inclusion portion 6a including the outer peripheral surface of the aggregate 4 and upper and lower edges of the inclusion portion 6a, and is used for sewing to the second aggregate receiving sheet 7. A sewing allowance 6b is formed. The horizontal width of the first aggregate receiving sheet 6 is set to the same horizontal length as the horizontal width of the sheet body 1, and the open / close direction length (vertical length) includes the aggregate 4. The length is set by adding twice the vertical length of the sewing allowance 6b to the vertical length of the portion 6a. Further, the first aggregate receiving sheet 6 is located at both left and right end portions of the inclusion portion 6 a, and a notch window 6 c is formed by cutting off a length substantially corresponding to the shaft portion 4 a of the aggregate 4. .
On the other hand, the second aggregate receiving sheet 7 is sewn with a seam allowance 6b of the first aggregate receiving sheet 6, and includes an accommodating portion 7a for accommodating the aggregate 4 together with the containing portion 6a of the first aggregate receiving sheet 6. And a surplus length portion 7b extending in a length dimension set in advance in the vertical direction (opening / closing direction) outward of the housing portion 7a, and a second aggregate receiver The length in the left-right direction of the sheet 7 is set to the same length as the length in the left-right direction of the sheet body 1 and the first aggregate receiving sheet 6, and the length in the opening / closing direction (length in the vertical direction) is the accommodating portion. The length is set by adding the vertical length of the upper and lower surplus portions 7b to the vertical length of 7a.

そして、第一骨材受けシート６は、上下の縫着代６ｂを、各端縁部が上方を向く状態として第二骨材受けシート７の一方の面における収容部７ａの上下にあてがい、これら各縫着代６ｂの上下二箇所において、それぞれ第二骨材受けシート７に縫い糸８を用いて縫着することで第二骨材受けシート７に一体化されるように設定されており、これによって、第一骨材受けシート６の包含部６ａと第二骨材受けシート７の収容部７ｂとにより骨材４を収容するための袋状部６ｄが形成されている。このとき、第一骨材受けシート６の縫着部６ｂの左右方向長さは、包含部６ａ（袋状部６ｄ）の左右長さよりも長く、第二骨材受けシート７の左右長さと同寸法に設定されている。このため、第一骨材受けシート６は、縫着代６ｂにより第二骨材受けシート７の左右幅全域において一体的に縫着されるものでありながら、包含部６ａの左右端位置に切り欠き窓６ｃが形成されている分、袋状部６ｄが第二骨材受けシート７よりも幅狭になるように形成されている。これによって、後述するように、骨材４の左右両端部の軸部４ａが前記切り欠き窓６ｃから外部に露出するように構成されている。   And the 1st aggregate receiving sheet 6 assigns the upper and lower sewing allowances 6b to the upper and lower sides of the accommodating part 7a in the one surface of the 2nd aggregate receiving sheet 7, with each edge part facing up. It is set so as to be integrated with the second aggregate receiving sheet 7 by sewing the sewing thread 8 to the second aggregate receiving sheet 7 at the upper and lower portions of each sewing allowance 6b. Accordingly, a bag-like portion 6 d for accommodating the aggregate 4 is formed by the inclusion portion 6 a of the first aggregate receiving sheet 6 and the accommodating portion 7 b of the second aggregate receiving sheet 7. At this time, the length in the left-right direction of the sewing portion 6b of the first aggregate receiving sheet 6 is longer than the left and right length of the inclusion portion 6a (bag-like portion 6d), and is the same as the left and right length of the second aggregate receiving sheet 7. Set to dimensions. Therefore, the first aggregate receiving sheet 6 is integrally sewn in the entire left and right width of the second aggregate receiving sheet 7 by the sewing allowance 6b, but is cut at the left and right end positions of the inclusion portion 6a. Since the notch window 6 c is formed, the bag-like portion 6 d is formed to be narrower than the second aggregate receiving sheet 7. As a result, as will be described later, the shaft portions 4a at the left and right ends of the aggregate 4 are configured to be exposed to the outside from the cutout window 6c.

前記縫着状態となった第一、第二骨材受けシート６、７は、第一、第二骨材受けシート６、７により形成された袋状部６ｄがシート体１の裏面側に突出するべく、第二骨材受けシート７の他方の面をシート体１の裏面に突きあて、前記収容部７ａを避けた部位、即ち、上下の縫着代６ｂ当接部よりも上下方向外方に位置する余長部７ｂとシート体１とのあいだをそれぞれ溶着することにより、シート体１と第二骨材受けシート７との一体化がなされるように設定されている。これによって、シート体１の裏面に、第一、第二骨材受けシート６、７により構成された袋状部６ｄを備えた骨材収容部Ｈが裏面側に突出する状態で形成されている。
このとき、第一、二骨材受けシート６、７同士の縫着部は、シート体１の裏面側にのみ露出して、表面側に露出することがなく、これによって、意匠性の高いシート体１とすることができるうえ、シート体１を、骨材収容部Ｈが形成される裏面を外側（表面を内側）として巻き取りドラム３に巻装したときに、縫着部は裏面側（外側）に露出していて、縫着部が巻き取りドラム３や、先行して巻き取りドラム３に巻装されたシート体１に擦れることがないうえ、後行して巻き重ねられるシート体１に対しては、外側に突出する骨材４により縫着部と離間した状態となっていてシート体１を擦るようなことがなく、もって、シート体の保護を図れるように構成されている。
また、第二骨材受けシート７の袋状部６ｄを構成する縫着部に対向する部位は、シート体１に溶着されることがないので、第一、第二骨材受けシート６、７のあいだの縫い糸８を切り取ることができ、これによって、第一骨材受けシート６だけをシート体１から取り外すことが可能となり、シート体を、骨材４の数が少ないタイプ、あるいは、骨材４を用いないタイプのシートシャッター装置に変更することもできるように構成されている。 The first and second aggregate receiving sheets 6 and 7 in the sewn state are such that the bag-like portion 6d formed by the first and second aggregate receiving sheets 6 and 7 protrudes from the back side of the sheet body 1. In order to do so, the other surface of the second aggregate receiving sheet 7 is abutted against the back surface of the sheet body 1 so as to avoid the accommodating portion 7a, that is, outward in the vertical direction from the upper and lower seam allowance 6b contact portion It is set so that the sheet body 1 and the second aggregate receiving sheet 7 can be integrated by welding the surplus length portion 7b positioned at the position and the sheet body 1, respectively. As a result, an aggregate housing portion H provided with a bag-like portion 6d composed of the first and second aggregate receiving sheets 6 and 7 is formed on the back surface of the sheet body 1 so as to protrude to the back surface side. .
At this time, the sewn portion between the first and second aggregate receiving sheets 6 and 7 is exposed only on the back surface side of the sheet body 1 and is not exposed on the front surface side. When the sheet body 1 is wound around the take-up drum 3 with the back surface on which the aggregate housing portion H is formed as the outside (the surface is the inside), the sewn portion is the back side ( The sheet body 1 that is exposed to the outside and does not rub against the take-up drum 3 or the sheet body 1 that has been wound on the take-up drum 3 in advance, and that is wound afterward. On the other hand, it is configured to protect the sheet body without being rubbed against the sheet body 1 because it is separated from the sewn portion by the aggregate 4 protruding outward.
Moreover, since the site | part which opposes the sewing part which comprises the bag-shaped part 6d of the 2nd aggregate receiving sheet 7 is not welded to the sheet | seat body 1, the 1st, 2nd aggregate receiving sheets 6 and 7 are used. Can be cut off, so that only the first aggregate receiving sheet 6 can be detached from the sheet body 1, and the sheet body can be a type with a small number of aggregates 4 or an aggregate. 4 can be changed to a type of sheet shutter device that does not use 4.

ここで、第二骨材受けシート７の余長部７ｂの長さは、本実施の形態では、袋状部６ｄを構成する収容部７ａの長さよりも長く、該袋状部６ｄにおける上下長さの二倍には満たない長さに設定されているが、該余長部７ｂの長さを長くすることでシート体１への一体化強度を大きくすることが可能であり、シート体１の大きさ、骨材４の強度、配設間隔等の設置環境に基づいて余長部７ｂの長さを適宜変化させることにより、骨材収容部Ｈの一体化強度を調整することが可能となり、これによって、使用条件に合ったシートシャッター装置を構成することが可能となるように構成されている。   Here, in the present embodiment, the length of the extra length portion 7b of the second aggregate receiving sheet 7 is longer than the length of the accommodating portion 7a constituting the bag-like portion 6d, and the upper and lower lengths in the bag-like portion 6d. Although the length is set to be less than twice the length, it is possible to increase the integrated strength to the sheet body 1 by increasing the length of the extra length portion 7b. It is possible to adjust the integrated strength of the aggregate housing portion H by appropriately changing the length of the extra length portion 7b based on the installation environment such as the size of the material, the strength of the aggregate 4 and the arrangement interval. Thus, the sheet shutter device can be configured in accordance with the use conditions.

一方、前記骨材４は、金属材によりパイプ状に形成され、シート体１に剛性及び重量を付与するものであるが、骨材４の大径な本体部４ｂにおける左右長さは、前記左右一対のガイドレール５の対向間隔よりも短く設定され、該本体部４ｂから外部に突出する軸部４ａを含めた左右長さが、シート体１の左右長さと同長さとなるように設定されている。
そして、前記骨材４は、シート体１の裏面に第一、第二骨材受けシート６、７により形成された骨材収容部Ｈの袋状部６ｄに収容されるが、このとき、骨材４は、袋状部６ｄの左右方向両端部に形成された切り欠き窓６ｃを介して収容することができるように設定されている。このとき、袋状部６ｄに収容された骨材本体部４ｂから突出する軸部４ａは、切り欠き窓６ｃから外部に露出するように設定されており、該外部に露出する軸部４ａと、シート体１、第一骨材受けシート６の上下の縫着代６ｂ、第二骨材受けシート７の左右両側縁とがガイドレール５のガイド溝５ａに嵌挿されるように設定されている。
ここで、袋状部６ｄを構成する第一、第二骨材受けシート６、７同士は、前述したように、シート体１と同様の左右幅方向一体にわたって縫着されている。これによって、骨材４（袋状部）に大きな負荷が作用したとしても、縫着部が骨材４の長さと同じ長さになっているため、縫着部における左右端部がほつれて剥離するような現象を発生しにくくできるうえ、発生したとしても、該剥離した縫着代６ｂが開口部にまで露出するような事は起こりにくく、もって耐久性の向上を果せるように構成されている。
尚、骨材４は、袋状部６ｄを構成する第一骨材受けシート包含部６ａとのあいだにリベット４ｃ止めすることによりにより固定されており、これによって、骨材４の左右方向の位置規制、ならびに、回転規制がなされるように設定されている。 On the other hand, the aggregate 4 is formed in a pipe shape with a metal material, and gives rigidity and weight to the sheet body 1. The left and right lengths of the large-diameter main body portion 4 b of the aggregate 4 are The left and right lengths including the shaft part 4a protruding outward from the main body part 4b are set to be the same as the left and right lengths of the sheet body 1 and are set to be shorter than the facing interval between the pair of guide rails 5. Yes.
And the said aggregate 4 is accommodated in the bag-like part 6d of the aggregate accommodating part H formed in the back surface of the sheet | seat body 1 by the 1st, 2nd aggregate receiving sheets 6 and 7, The material 4 is set so that it can be accommodated through the notch windows 6c formed at both left and right end portions of the bag-like portion 6d. At this time, the shaft portion 4a protruding from the aggregate body portion 4b accommodated in the bag-shaped portion 6d is set to be exposed to the outside from the cutout window 6c, and the shaft portion 4a exposed to the outside, The sheet body 1, the upper and lower seam allowances 6 b of the first aggregate receiving sheet 6, and the left and right side edges of the second aggregate receiving sheet 7 are set to be inserted into the guide grooves 5 a of the guide rail 5.
Here, the first and second aggregate receiving sheets 6, 7 constituting the bag-like portion 6 d are sewn together in the left-right width direction as in the case of the sheet body 1 as described above. As a result, even if a large load acts on the aggregate 4 (bag-like portion), the sewn portion is the same length as the length of the aggregate 4, so that the left and right end portions of the sewn portion fray and peel off. Such a phenomenon can be made difficult to occur, and even if it occurs, it is difficult for the peeled seam allowance 6b to be exposed to the opening, thereby improving durability. .
The aggregate 4 is fixed by being fastened with a rivet 4c between the first aggregate receiving sheet containing portion 6a constituting the bag-like portion 6d, whereby the position of the aggregate 4 in the left-right direction is fixed. Regulations and rotation restrictions are set.

叙述の如く構成された本形態において、シートシャッター装置におけるシート体１は、巻き取りドラム３の正逆回転に伴い巻き出し、巻き戻しがなされて開口部の開閉を行うが、このものにおいて、シート体１に剛性を付与する骨材４は、シート体１の裏面に設けられた骨材収容部Ｈに収容されている。そして、前記骨材収容部Ｈは、第一、第二骨材受けシート６、７を用い、第一骨材受けシート６を第二骨材受けシート７に縫着することにより袋状部６ｄを形成し、該袋状部６ｄが縫製された第二骨材受けシート７の余長部７ｂを、シート体１に溶着することによりシート体１に設けられている。この結果、骨材収容部Ｈは、二枚のシート材を用いて形成される分、補強がなされたものになるうえ、従来の袋状部をシート体に直接設けたもののように、袋状部とシート体との一体化面積が小さくなってしまうことがなく、一体化強度を高めることができる。しかも、第二骨材受けシート余長部７ｂの面積、つまり、シート体１への溶着面積を大きくすることにより、骨材収容部Ｈのシート体１への一体化強度を一層高めることが可能となる。   In the present embodiment configured as described, the sheet body 1 in the sheet shutter device is unwound and unwound in accordance with the forward and reverse rotation of the winding drum 3 to open and close the opening. The aggregate 4 that imparts rigidity to the body 1 is accommodated in an aggregate accommodating portion H provided on the back surface of the sheet body 1. The aggregate housing portion H uses the first and second aggregate receiving sheets 6 and 7 and sews the first aggregate receiving sheet 6 to the second aggregate receiving sheet 7 to form a bag-like portion 6d. The surplus length portion 7b of the second aggregate receiving sheet 7 in which the bag-like portion 6d is sewn is welded to the sheet body 1 to be provided on the sheet body 1. As a result, the aggregate housing portion H is reinforced by the amount formed by using two sheets of material, and also has a bag shape like a conventional bag-like portion provided directly on the sheet body. The integrated area of the part and the sheet body is not reduced, and the integrated strength can be increased. In addition, by increasing the area of the second aggregate receiving sheet surplus length portion 7b, that is, the welding area to the sheet body 1, it is possible to further increase the integrated strength of the aggregate housing portion H to the sheet body 1. It becomes.

さらに、本発明が実施されたものにあっては、第二骨材受けシート７を、第一骨材受けシート６が縫着される部位を除く余長部７ｂにおいてシート体１に溶着する構成としたので、骨材収容部Ｈのシート体１への一体化強度を、余長部７ｂの上下方向長さを調整することにより、設置環境にあった一体化強度とすることができる。しかも、このものでは、縫着部が溶着されることがないので第一骨材受けシート6を第二骨材受けシート７から取り外すのが容易で、骨材４を用いるタイプから骨材４を減らしたり、骨材４を用いないタイプに変更することが容易に実現できる。   Furthermore, in the embodiment of the present invention, the second aggregate receiving sheet 7 is welded to the sheet body 1 at the extra length portion 7b excluding the portion where the first aggregate receiving sheet 6 is sewn. Therefore, the integrated strength of the aggregate housing portion H to the sheet body 1 can be made the integrated strength suitable for the installation environment by adjusting the vertical length of the extra length portion 7b. Moreover, in this case, since the sewn portion is not welded, it is easy to remove the first aggregate receiving sheet 6 from the second aggregate receiving sheet 7, and the aggregate 4 from the type using the aggregate 4 can be removed. It is possible to easily reduce or change to a type that does not use the aggregate 4.

そのうえ、このものでは、袋状部６ｄが形成されている第一、第二骨材受けシート６、７をシート体１の裏面に設けたとき、袋状部６ｄを縫い付けることにより形成される縫着部がシート体１の表面に露出することがなく、意匠性のよいシート体１とすることができるうえ、巻き取りドラム３に巻装したとき、骨材収容部Ｈが設けられるシート体１の裏面が外側になる状態で巻装することにより、縫着部の縫い糸８によりシート体１を傷つけることがなく、シート体１の保護を図ることができる。   Moreover, in this case, when the first and second aggregate receiving sheets 6 and 7 on which the bag-like portion 6d is formed are provided on the back surface of the sheet body 1, the bag-like portion 6d is sewn. The sewn part is not exposed on the surface of the sheet body 1, and can be made a sheet body 1 with good design, and the sheet body on which the aggregate housing portion H is provided when wound around the take-up drum 3. By winding in a state where the back surface of 1 is on the outside, the sheet body 1 can be protected without being damaged by the sewing thread 8 of the sewn portion.

さらに、このものにおいて、第一、第二骨材受けシート６、７は、両者共にシート体１の左右幅と同寸法に設定されていて、シート体1の左右両端縁部に至るまで縫着、そして、溶着されている。この結果、骨材４に大きな負荷が作用しても第一、第二骨材受けシート６、７の縫着部が剥離しにくく、また、剥離したとしても、従来の袋状部の端部が開口部に位置するもののようにすぐに剥離した部分が開口部に露出してしまうことがなく、耐久性に優れたものにできる。   Furthermore, in this, both the first and second aggregate receiving sheets 6 and 7 are set to have the same dimensions as the left and right widths of the sheet body 1 and are sewn up to the left and right end edges of the sheet body 1. And it is welded. As a result, even if a large load is applied to the aggregate 4, the sewn portions of the first and second aggregate receiving sheets 6, 7 are difficult to peel off. The part which peeled immediately like what is located in an opening part is not exposed to an opening part, but it can be made excellent in durability.
