Description

本発明は、工場や倉庫等建物の出入口や間仕切り部分に設置されるシートシャッタに関する。   The present invention relates to a sheet shutter installed at an entrance / exit of a building such as a factory or a warehouse.

従来、工場や倉庫等建物の出入口や間仕切り部分に立設される左右の支柱に、シャッタ用のシートをモータの正逆回転によって昇降し開閉作動させるシートシャッタで、間口巾方向の通直性を保持する複数の心材をシート繰り出し方向(長さ方向)に配置し、シートの接地部の上方近傍に上記心材より大重量の重錘心材を設けると共に、接地部内に可撓性と弾力性を有して弾性変形する緩衝心材を設けた構成のものは既に公知である(例えば特許文献1。)。
そして、上記シートシャッタはシートの左右巾内に設けた心材及び重錘心材並びに可撓心材の両側に、支柱のガイド溝内に挿入される支持部を有する心材支持具を着脱可能に取付け、シートの両側辺部と共に支持部をガイド溝に挿入することにより、支柱に沿ってシートを案内移動させる構成にしている。

JP 2006-225936 A

上記特許文献1で示されるシートシャッタは、シート下方の可撓心材の直上方に接当緩衝間隔を設けて重錘心材を配置しているので、接当物に接当した接地部が上方に撓むとき接当緩衝間隔を撓み代として、接地部の撓みを許容して接当衝撃を緩和するので接当物の損傷を防止する。また硬質で重量のある重錘心材は接当緩衝間隔を有しているので、接地部を介して接当物や人体との直接的な接当を回避できる等の利点がある。
然し、上記シートシャッタは心材及び重錘心材並び緩衝心材の両側を共に支柱のガイド溝に挿入支持しているので、シート下降時に接地部が接当物に接当した場合に、接当物に接当規制された状態でシートの下降によって、可撓心材には上方の重錘心材並びに心材が順次接当し合い乱れて一側に傾斜した状態になる。
In the sheet shutter shown in Patent Document 1, the weight core material is disposed with a contact buffering interval provided immediately above the flexible core material below the seat, so that the grounding portion that contacts the contact object is located upward. When bending, the contact buffering interval is set as a bending allowance, and the contact portion is allowed to be bent to reduce the contact impact, thereby preventing the contact object from being damaged. In addition, since the heavy and heavy weight core material has a contact buffering interval, there is an advantage that direct contact with a contact object or a human body can be avoided via the grounding portion.
However, the sheet shutter supports both the core material, the weight core material, and the buffer core material by inserting both of them into the guide groove of the support column, so that when the grounding part contacts the contact object when the seat is lowered, When the sheet is lowered in a state where contact is restricted, the upper weight core material and the core material are in contact with each other in order to be in contact with the flexible core material and are inclined to one side.

そして、上記のように各心材が接当して傾斜作動を生じた状態で接当負荷が継続するとき、可撓心材及び重錘心材並びに心材の側端は互いに接触して干渉し合うので、さらに前後方向の負荷を受けたりすると、可撓心材及び重錘心材等がガイド溝から離脱し難くなったり離脱不能となり、心材類並びにガイドレールや支柱を損傷させる等の接当トラブルを生ずる。
そこで各心材をその両側に、プラスッチック成形により破断強度が設定された心材支持具を着脱交換自在に設けてガイド溝内に挿入し摺動案内させる構成が試みられるが、この手段によっても各心材類が集合しその心材支持具が干渉し合う状態になると、ガイド溝からの抜け出しを困難にする、また心材支持具がうまく破断されないで上記のような接当トラブルが解消されないと言う問題がある。
And, as described above, when the contact load continues in the state where each core material contacts and causes an inclination operation, the side ends of the flexible core material and the weight core material and the core material contact each other and interfere with each other. Further, when subjected to a load in the front-rear direction, the flexible core material, the weight core material, and the like are difficult to remove from the guide groove or cannot be detached, causing contact troubles such as damage to the core materials, the guide rail, and the support column.
Therefore, an attempt is made to install each core material on both sides thereof with a core material support having a breaking strength set by plastic molding so that the core material can be freely attached and detached and inserted into the guide groove for sliding guide. When the core members gather and the core material support members interfere with each other, there is a problem that it is difficult to pull out from the guide groove, and the core material support members are not broken well and the above contact troubles are not solved.

上記課題を解決するためのシートシャッタは、第1に、左右方向に通直な複数の心材7を上下方向に心材配置間隔Hを有して支持し、シート下端に床面と接地させる接地部11を設けたシート2の側端を、シャッタ取付口を形成する支柱3,3のガイド溝26に進退移動可能に収容して開閉作動を行うシートシャッタ1において、前記シート2の接地部11に可撓性を有して弾性変形する可撓心材13と共に、該可撓心材13の上方に可撓心材13より大重量で剛性を有する重錘心材7aを心材配置間隔Hより短い接当緩衝間隔Lを有して略平行状に設け、且つ重錘心材7aを上記ガイド溝26に挿入支持される複数の心材7及び可撓心材13の全長より短く形成して、重錘心材7aの両側に可撓性を有する心材支持幅Sを形成した側辺部2bをガイド溝26内に挿入支持させることを特徴としている。   A sheet shutter for solving the above-mentioned problems is as follows.

第4に、心材7及び可撓心材13の両側に、ローラ22を軸支する支持杆21を着脱自在に設けると共に、該支持杆21をローラ22の外径より小径杆で形成することを特徴としている。   Fourth, the support rod 21 that pivotally supports the roller 22 is detachably provided on both sides of the core material 7 and the flexible core material 13, and the support rod 21 is formed with a smaller diameter rod than the outer diameter of the roller 22. It is said.

第5に、心材7に設ける心材支持具9をプラスッチック材で形成すると共に、可撓心材13の両側に設ける最下心材支持具9aを上記心材支持具9より重量及び破断強度の大きい部材で形成することを特徴としている。   Fifth, the core material support 9 provided on the core material 7 is formed of a plastic material, and the lowermost core material support 9a provided on both sides of the flexible core material 13 is formed of a member having a weight and breaking strength larger than those of the core material support 9.

It is characterized by pressing and urging toward the support direction side.

本発明は、以上のように構成したことにより次のような効果を奏する。可撓心材の上方に接当緩衝間隔を有して重錘心材を設け、且つ重錘心材を心材及び可撓心材の全長より短くしてシートに支持させることにより、重錘心材の両側をガイド溝内に挿入させないで、心材支持幅を有する側辺部をガイド溝内に挿入支持し、接地部が接当物に接当した際に、接当緩衝間隔及び心材支持幅を介して可撓心材を自由に撓ませ、且つ大きな抵抗を伴うことなく傾斜作動させるので接当トラブルを防止することができる。また過大な接当負荷を受ける場合に、可撓心材をガイドレールから速やかに離脱させ心材外し作動をスムーズに行わせることができる。   The present invention has the following effects by being configured as described above. A weight core material is provided above the flexible core material with a contact buffering interval, and the weight core material is shorter than the total length of the core material and the flexible core material, and is supported by the sheet to guide both sides of the weight core material. Without inserting into the groove, the side part having the core support width is inserted and supported in the guide groove, and when the grounding part comes into contact with the contact object, it is flexible through the contact buffering interval and the core support width. Since the core material is flexed freely and tilted without significant resistance, contact troubles can be prevented. Further, when receiving an excessive contact load, the flexible core material can be quickly detached from the guide rail, and the core material can be removed smoothly.

可撓心材の両側にローラを設けてガイド溝内で転接させることにより、可撓心材の下降を速やかに行わせ重錘心材との接当緩衝間隔を保持した開閉作動をスムーズに行わせることができる。また接当物との接当時における心材外し作動をローラの転接により無理なく行わせることができる。   By providing rollers on both sides of the flexible core material and rolling them in the guide groove, the flexible core material can be quickly lowered and the opening / closing operation can be performed smoothly while maintaining the contact buffer interval with the weight core material. Can do. Moreover, the operation of removing the core material at the time of contact with the contact object can be performed without difficulty by rolling the roller.

心材の両側において、小径な支持杆の先端に軸支されるローラをガイド溝の一側に偏心させて設けることにより、シートの開閉作動時にローラをガイド溝の一側のガイド面に転接させて、シートの開閉を安定よく軽快に行うことができる。またシートを例えば前側ガイド面に近接させた状態で下降させることができ、シート閉鎖時の気密性を高めることができる。   On both sides of the core material, a roller that is pivotally supported by the tip of a small-sized support rod is eccentrically provided on one side of the guide groove, so that the roller is brought into rolling contact with the guide surface on one side of the guide groove when the sheet is opened and closed. Thus, the seat can be opened and closed stably and lightly. Further, the seat can be lowered, for example, in the state of being close to the front guide surface, and the airtightness when the seat is closed can be improved.

心材及び可撓心材の両側に設ける支持杆を、ローラの外径より小径杆で形成することにより、シートの側辺部をガイド溝内で支持杆に近接させることができ、ガイド面との摺接磨耗を防止した開閉作動をスムーズに行うことができる。   By forming the support rods provided on both sides of the core material and the flexible core material with a smaller diameter rod than the outer diameter of the roller, the side portion of the sheet can be brought close to the support rod within the guide groove, and the sliding surface with the guide surface can be made. Opening and closing operations that prevent contact wear can be performed smoothly.

心材に設ける心材支持具をプラスッチック材で形成することにより、接当負荷等が過大である場合に支持杆を確実に破断させるので、心材並びにガイド溝等の損傷を防止することができる。また可撓心材の両側に設ける最下心材支持具は鉄材等で形成するので、可撓心材の両側の重量を大きくして接地部の下降を助成すると共に、接当物との接当負荷或いは強風負荷を受ける際に、可撓心材をガイド溝から安易に離脱させることなく、接地部の通直性を保持したシートの開閉を行うことができる。   By forming the core material support provided on the core material with a plastic material, the support rod is surely broken when the contact load or the like is excessive, so that damage to the core material and the guide groove can be prevented. In addition, since the lowermost core support provided on both sides of the flexible core is formed of iron or the like, the weight on both sides of the flexible core is increased to assist the lowering of the grounding portion, and the contact load with the contact object or When receiving a strong wind load, the flexible core can be easily opened and closed without easily removing the flexible core from the guide groove.

重錘心材の長さを、両側に最下心材支持具を備える可撓心材の長さと略同程度にすることにより、シートの下方部位において、重錘心材の側方に形成される心材支持幅と接当緩衝間隔と可撓心材等からなる可撓性経路を形成し、上下及び前後方向の可撓性を十分に備えることができる。また可撓心材の両側に設ける最下心材支持具と、可撓心材の直上に短い接当緩衝間隔を有して支持される重錘心材とからなる剛性経路を形成し、シートの下方部位の通直性を確保するので、強風等による前後方向の負荷に対してもシート外れを防止した開閉をスムーズに行うことができる。   By making the length of the weight core material approximately the same as the length of the flexible core material having the lowermost heart material support on both sides, the core material support width formed on the side of the weight core material at the lower part of the sheet In addition, a flexible path composed of a contact buffering interval and a flexible core material can be formed, and sufficient flexibility in the vertical and front-rear directions can be provided. Further, a rigid path composed of a lowermost core support provided on both sides of the flexible core and a weight core supported with a short contact buffer interval immediately above the flexible core is formed, and a lower portion of the seat is formed. Since straightness is ensured, it is possible to smoothly perform opening and closing that prevents the seat from being detached even in a longitudinal load caused by a strong wind or the like.

ガイド溝の一側のガイド面に、ガイド溝の開口部を可撓性を有して塞ぐ気密保持部材を設け、該気密保持部材によってシートをローラの偏心支持方向側に押接付勢することにより、気密保持部材はその先端を撓ませてシートを押接付勢し、偏心支持方向にあるガイド面へのローラの転接を安定させる。また気密保持部材は閉鎖時にシートの側辺部を上記ガイド面に接当させてシートの気密性を高めることができる。   An airtight holding member that flexibly closes the guide groove opening is provided on the guide surface on one side of the guide groove, and the sheet is pressed and urged toward the eccentric support direction side of the roller by the airtight holding member. Thus, the airtight holding member bends the tip and presses and urges the sheet to stabilize the rolling contact of the roller to the guide surface in the eccentric support direction. The airtight holding member can improve the airtightness of the sheet by closing the side of the sheet against the guide surface when closed.

以下図示する本発明の一実施形態について説明する。図1,図2において符号1は本発明に係わるシートシャッタであり、建物等の出入口(間口)に立設するシャッタフレームにシート(シャッタ)2を進退移動させることにより出入口を開閉することができる。このシートシャッタ1のシャッタフレームは、出入口を形成する建物の支柱又は壁面に沿って立設固定されてシャッタ取付口(シート開閉間隔)を形成する左右の支柱(サイドフレーム)3,3と、該支柱3,3の上部を連結して取付支持される中空箱体状のシートケース4とによってゲート状フレームに構成される。   Hereinafter, an embodiment of the present invention shown in the drawings will be described. 1 and 2, reference numeral 1 denotes a seat shutter according to the present invention, which can be opened and closed by moving the seat (shutter) 2 forward and backward on a shutter frame standing at the entrance (entrance) of a building or the like. . The shutter frame of the seat shutter 1 includes left and right support columns (side frames) 3 and 3 that are erected and fixed along a support column or wall surface of a building that forms an entrance / exit to form a shutter mounting opening (seat opening / closing interval); A gate-like frame is constituted by a hollow box-like seat case 4 connected and supported by connecting the upper portions of the columns 3 and 3.

上記シートケース4は内部に、シート2を巻取繰出回転可能とする中空筒状の巻取ドラム5が設置される。支柱3,3は内部にシート2を後述するシートガイド構造を以て昇降動作可能に構成される。
以下各部の構成について説明する。先ずシートケース4は従来のものと同様な構成によって、中空状のカバー枠体の両端に端板4a,4aが着脱可能に嵌め込まれ、カバー枠体の下側辺にシート2の通路(昇降路)4bを開口したボックス型形状としている。
The sheet case 4 is provided with a hollow cylindrical winding drum 5 that allows the sheet 2 to be wound and rotated. The support columns 3 and 3 are configured so that the seat 2 can be moved up and down by a sheet guide structure which will be described later.
The configuration of each part will be described below. First, the seat case 4 has a configuration similar to that of the conventional case, and end plates 4a and 4a are detachably fitted to both ends of the hollow cover frame, and the passage (hoistway) of the seat 2 is formed on the lower side of the cover frame. ) It is a box shape with 4b open.

右方の端板4aには、巻取ドラム5の端部内に収容される円柱状のモータ6が取付ネジによって着脱可能に取付固定される。
モータ6は巻取ドラム5の右方端部内に挿入された状態で、巻取ドラム5の右方をモータ軸に設けた駆動板6aによって係合支持している。また巻取ドラム5の左方は左方の端板4aに軸支した軸支板6bによって支持される。
A columnar motor 6 accommodated in the end portion of the winding drum 5 is detachably attached and fixed to the right end plate 4a by an attaching screw.
The motor 6 is engaged and supported on the right side of the winding drum 5 by a drive plate 6a provided on the motor shaft while being inserted into the right end of the winding drum 5. The left side of the take-up drum 5 is supported by a shaft support plate 6b that is supported by the left end plate 4a.

シート2は透光性及び可撓性を有する長方形の合成樹脂性幕体からなり、その上端(基部側)を巻取ドラム5の軸芯方向に沿って取付固定し、巻取ドラム5の正逆回転(巻取繰出回転)による繰り出し下降及び巻き上げ上昇によって開閉作動される。またシート2は、幕体の長手方向(繰り出し方向)の略全長にわたり、側面視で袋状に形成された複数の心材取付部2aが所定の心材配置間隔(ピッチ)Hを有して設けられ、各心材取付部2a内に一定の剛性を有するパイプ状の心材7,7及び重錘心材7a等が挿入される。これによりシート2は巾方向の通直性を保持して、開閉作動時の撓み及び風による撓みが防止される。   The sheet 2 is made of a rectangular synthetic resin curtain having translucency and flexibility. The upper end (base side) of the sheet 2 is attached and fixed along the axial direction of the winding drum 5. The opening / closing operation is performed by the lowering of the feeding and the raising of the winding by reverse rotation (winding and feeding rotation). Further, the sheet 2 is provided with a plurality of core material attachment portions 2a formed in a bag shape in a side view over a substantially entire length in the longitudinal direction (feeding direction) of the curtain body with a predetermined core material arrangement interval (pitch) H. The pipe-shaped core materials 7 and 7 having a certain rigidity, the weight core material 7a and the like are inserted into each core material mounting portion 2a. Thereby, the sheet | seat 2 maintains the straightness of the width direction, and the bending at the time of opening / closing operation | movement and the bending by a wind are prevented.

図示例のシート2は図2〜図5で示すように、一枚状のシート2の一側面に対し心材取付部2aを、相隣る心材7と心材7の間隔毎にシート袋形成部材によって袋状に形成し、この心材取付部2a内に袋部の一側から心材7を挿入し、且つ心材7の両端に後述する心材支持具9を挿入固定する構造にしている。
尚、シート2は上記の製作手段に限定することなく、例えば相隣る上下の心材7と心材7との間隔毎に形成したシート片の上下端を上下に重ね、各重接端を溶着又は接着等の接合手段によって接合させて、心材7を挿入する袋状の心材取付部2aを形成することもできる。
As shown in FIGS. 2 to 5, the sheet 2 in the illustrated example has a core material mounting portion 2 a attached to one side surface of the single sheet 2 by a sheet bag forming member at every interval between the adjacent core material 7 and the core material 7. The core material 7 is formed in a bag shape, and the core material 7 is inserted into the core material attaching portion 2a from one side of the bag portion, and the core material support 9 described later is inserted and fixed to both ends of the core material 7.
Note that the sheet 2 is not limited to the above-described manufacturing means. For example, the upper and lower ends of the sheet pieces formed at intervals between the adjacent upper and lower core materials 7 and the core material 7 are vertically stacked, and the respective heavy contact ends are welded or It is also possible to form the bag-shaped core material attaching portion 2a into which the core material 7 is inserted by bonding by a bonding means such as adhesion.

また心材7の全長は、その両側が後述する支柱3が有するガイドレール3a内に挿入される長さとする。この図示例では心材7の全長は、間口巾より短い長さの丸パイプ材からなる心材7の左右端に、シート側辺部2bの心材取付部2aから後述する心材支持具9,9を挿入した長さにしている。
そして、図2,図3で示すようにシート2は最下端に、上記のような剛性の高い鉄製丸パイプ材を収容しないで、巾方向の通直性を保持しつつ可撓性を有して接地すると共に、シート2が下降するとき接当物や床面と緩衝性を有して接当する接地部11を備えている。
Moreover, let the full length of the core material 7 be the length by which the both sides are inserted in the guide rail 3a which the support | pillar 3 mentioned later has. In this illustrated example, the core material 7 is inserted into the left and right ends of the core material 7 made of a round pipe material having a length shorter than the front width from the core material mounting portion 2a of the seat side portion 2b. The length is made.
As shown in FIGS. 2 and 3, the sheet 2 has flexibility at the lowermost end while maintaining the straightness in the width direction without containing the rigid steel round pipe material as described above. And a grounding portion 11 that has contact with a contact object or a floor surface when the seat 2 descends.

この接地部11は、シート2の下端を折り返して袋状に形成される第1の収容部12内に、一定の通直性及び弾力性を有する可撓心材13を挿入し、第2の収容部15内に剛性を有して錘材となる前記心材7と同様のパイプ材からなる重錘心材7aを挿入している。また重錘心材7aは可撓心材13の上方に、心材7と重錘心材7aの心材間隔Hより短い接当緩衝間隔Lを設けて保持される。   The grounding portion 11 is formed by inserting a flexible core material 13 having a certain straightness and elasticity into a first housing portion 12 formed in a bag shape by folding back the lower end of the sheet 2, thereby providing a second housing. A weight core material 7 a made of a pipe material similar to the core material 7 having rigidity and being a weight material is inserted into the portion 15. The weight core material 7a is held above the flexible core material 13 with a contact buffering interval L shorter than the core material interval H between the core material 7 and the weight core material 7a.

尚、シート下端を折り返して袋状に形成される収容部12,15は、その接合面を溶着又は接着等の手段によって接合し、可撓性及び耐摩耗性を有する接地カバー16によってチューブ状断面をなすように下方から折り曲げて被覆される。
また図示例の接地部11は接地カバー16内において、第1の収容部12の外周にゴム又はスポンジ材で形成される緩衝部材17を設けて覆っている。
The storage portions 12 and 15 formed in a bag shape by folding back the lower end of the sheet are joined together by means such as welding or adhesion, and the tube-shaped cross section is formed by a ground cover 16 having flexibility and wear resistance. It is bent and coated from below so as to form
Further, the grounding portion 11 in the illustrated example covers and covers a buffer cover 17 formed of rubber or sponge material on the outer periphery of the first housing portion 12 in the grounding cover 16.

これによりシート2は、接地部11の可撓心材13並びに緩衝部材17の重量に、重錘心材7aの重量を加えた接地部重量によって下降移動を付勢することができ、また下降に伴い接地部11が床面に接当したとき、可撓性を有する接地カバー16が重量によって押圧され変形しながら、床面に倣って気密性を有した接地を行う。   As a result, the seat 2 can be urged to move downward by the weight of the grounding portion obtained by adding the weight of the weight core material 7a to the weight of the flexible core material 13 and the buffer member 17 of the grounding portion 11, and is also grounded as it descends. When the part 11 comes into contact with the floor surface, the grounding cover 16 having flexibility is pressed and deformed by weight, and performs grounding having airtightness following the floor surface.

尚、接地部11はシート2が巻取ドラム5によって巻き上げられた最上昇位置において、シートケース4の通路4bを下方から塞ぐように待機させ、且つ重錘心材7bを巻取ドラム5の下半部に位置させる。そして、巻取ドラム5が逆転されるとき巻取ドラム5の下半部に位置する重錘心材7bは、接地部11の可撓心材13が軽量構造であっても、可撓心材13に近接させた重量によってシート2の繰り出し下降移動を付勢し、閉鎖作動を速やかにすることができる。   The grounding portion 11 waits to close the passage 4b of the seat case 4 from below at the highest position where the sheet 2 is wound up by the winding drum 5, and the weight core material 7b is placed in the lower half of the winding drum 5. To position. When the winding drum 5 is reversed, the weight core material 7b located in the lower half of the winding drum 5 is close to the flexible core material 13 even if the flexible core material 13 of the grounding portion 11 has a lightweight structure. The drawn-out and downward movement of the seat 2 is urged by the weight thus made, so that the closing operation can be quickly performed.

また接当緩衝間隔Lを上方の相隣る心材7,7の心材配置間隔Hより短くし、重量のある重錘心材7aを可撓心材13に近接させるので、重錘心材7aより上位にある複数の心材7の軽量化を図ることができ、シート2の上昇駆動付加を増大させないで、開作動をスムーズに行わせることができる。   Further, since the contact buffering interval L is shorter than the core arrangement interval H between the adjacent core members 7 and 7 and the heavy weight core material 7a is brought close to the flexible core material 13, it is higher than the weight core material 7a. The plurality of core members 7 can be reduced in weight, and the opening operation can be smoothly performed without increasing the drive for raising the seat 2.

次に図3〜図5を参照しシート2のガイド構造について説明する。このシートガイド構造は、各心材7と可撓心材13は略等しい長さになし、心材取付部2aと第1の収容部12とに心材7と可撓心材13のそれぞれを挿入支持している。そして、心材7と可撓心材13のそれぞれの両端部には、シート2の両側に形成される側辺部2b内に挿入される、支持杆21の先端にローラ22を軸支した、心材支持具9と最下心材支持具9aとを互換性を有して着脱自在に設けている。   Next, the guide structure of the sheet 2 will be described with reference to FIGS. In this sheet guide structure, each core material 7 and the flexible core material 13 have substantially the same length, and the core material 7 and the flexible core material 13 are inserted and supported in the core material mounting portion 2a and the first housing portion 12, respectively. . Further, at both ends of the core material 7 and the flexible core material 13, core material support in which a roller 22 is pivotally supported at the tip of a support rod 21 inserted into the side portion 2 b formed on both sides of the sheet 2. The tool 9 and the lowermost core material support tool 9a are interchangeably provided.

即ち、図3,図5で示すように心材支持具9は、丸パイプ材からなる心材7の両端内に、鍔付きの取付部23を所定の挿入代を有して内嵌支持し、該取付部23即ち心材7の中心に対しガイド偏心距離Gを有して偏心させた位置に支持杆21を一体的に形成し、該支持杆21の先端に形成した軸部25にローラ22を軸支している。そして、支持杆21は上記取付部23より小径にしており、これにより後述する側辺部2bの逃し間隔Kを形成するようにしている。尚、ローラ22は外径を心材7の外径より小径となし、軸支部22a側を硬質プラスッチック材とし、その外周の転接部22bを軟質プラスッチック材で形成している。   That is, as shown in FIG. 3 and FIG. 5, the core material support 9 supports and fits the hooked mounting portions 23 with a predetermined insertion margin in both ends of the core material 7 made of a round pipe material, A support rod 21 is integrally formed at a position eccentric with a guide eccentric distance G with respect to the center of the mounting portion 23, that is, the core material 7, and the roller 22 is attached to the shaft portion 25 formed at the tip of the support rod 21. I support. The support rod 21 has a smaller diameter than the mounting portion 23, thereby forming a clearance interval K of the side portion 2b described later. The roller 22 has an outer diameter smaller than the outer diameter of the core material 7, the shaft support 22a side is made of a hard plastic material, and the outer rolling contact portion 22b is made of a soft plastic material.

また心材支持具9は心材7の強度より弱い所定の曲げ負荷によって折れ破断を可能とするように、プラスッチック材による型成形によって一定の靱性を有し且つ廉価な構造で製作している。これによりシート2が接当トラブルを生じた際に、長大で高価格な心材7の破損を防止し、摩損したり接当物との接当により変形や破断をした心材支持具9のみを取り替えて、シートシャッタ1の修理や部品交換等のメンテナンス作業を簡単且つ廉価に行うようにしている。   The core material support 9 is manufactured to have a certain toughness and an inexpensive structure by molding with a plastic material so that it can be broken and broken by a predetermined bending load weaker than the strength of the core material 7. This prevents damage to the long and expensive core material 7 when the sheet 2 has contact problems, and replaces only the core material support 9 that is worn or deformed or broken by contact with the contact object. Thus, maintenance work such as repair of the seat shutter 1 and parts replacement is performed easily and inexpensively.

上記ガイド偏心距離Gは図3,図5で示すように、心材支持具9のローラ22を支柱3のガイドレール3aによって形成されるガイド溝26内に挿入し、ガイド溝26の前側ガイド面26aに転接するように偏心支持方向を定めた状態において、ローラ22の外周転接面は心材7の前側に位置しシート2の側辺部2bをやや後方に位置させることができる。これにより心材支持具9のローラ22は前側ガイド面26aに転接し、支持杆21を介しシート2の両側を案内支持しながら、後側ガイド面26bへの転接を規制して不規則に正逆回転することなく一方向回転を促進される。従って、シート2は上記心材支持具9の形状及びローラ22の偏心支持方向のセットにより、進退作動時のガイド溝26内での摺接抵抗を軽減し昇降作動を軽快に行うことができる。   As shown in FIGS. 3 and 5, the guide eccentric distance G is inserted into the guide groove 26 formed by the guide rail 3a of the column 3 by inserting the roller 22 of the core support 9 and the front guide surface 26a of the guide groove 26. In the state where the eccentric support direction is determined so as to be in rolling contact with each other, the outer peripheral rolling contact surface of the roller 22 is positioned on the front side of the core material 7 and the side portion 2b of the sheet 2 can be positioned slightly rearward. As a result, the roller 22 of the core material support 9 rolls into contact with the front guide surface 26a and guides and supports both sides of the sheet 2 via the support rod 21 while restricting rolling contact with the rear guide surface 26b and irregularly corrects. One-way rotation is promoted without reverse rotation. Therefore, the sheet 2 can be easily moved up and down by reducing the sliding resistance in the guide groove 26 during the advance / retreat operation by setting the shape of the core material support 9 and the eccentric support direction of the roller 22.

さらに、ローラ22は前側ガイド面26aに常時的に転接するので、従来のもののようにシート側辺部2bの局所を一側のガイド面(前側ガイド面)26aに強く押接することを防止して、非摺接状態でガイド溝26内をスムーズに移動させる。従って、ガイドレール3aとの摺接によるシート2の摩損や破れ等を防止すると共に、前側ガイド面26aの損耗も抑制することができる。
また支持杆21は取付部23より小径となしガイドレール3aの前側ガイド面26aとの間に、前記逃し間隔Kを形成しているので、前側ガイド面26aに摺接しようとする側辺部2bを逃し間隔K内に撓ませ、前側ガイド面26aとの強い摺接を防止することができる。
Further, since the roller 22 is always in rolling contact with the front guide surface 26a, it is possible to prevent the local side of the sheet side portion 2b from being strongly pressed against the one side guide surface (front guide surface) 26a as in the prior art. In the non-sliding contact state, the guide groove 26 is smoothly moved. Accordingly, it is possible to prevent the seat 2 from being worn or torn due to sliding contact with the guide rail 3a, and to suppress the wear of the front guide surface 26a.
Further, since the support rod 21 has a smaller diameter than the mounting portion 23 and the front guide surface 26a of the guide rail 3a, the clearance interval K is formed, so that the side portion 2b which is slidably in contact with the front guide surface 26a. Can be deflected within the clearance interval K and strong sliding contact with the front guide surface 26a can be prevented.

従って、ローラ22の外周面を心材7の外周前面よりやや内側に設けた場合でも、前側ガイド面26aとの強い摺接による側辺部2bの摩損を防止することができる。
尚、図4の点線で示すように、シート2の側辺部2bをローラ22の外側に延長させて気密性を高める場合には、該ローラ22に対面するシート部分を局部的に切開すると、ローラ22の転接を行わせることができる。またローラ22は上記のような心材支持具9を用いないで、ガイド溝26内に直接的に挿入させる心材7に設ける場合には、ローラ支持軸部分を心材7に対して変心支持方向に挿入して取付固定する等の構造によって行うことができる。
Accordingly, even when the outer peripheral surface of the roller 22 is provided slightly inside the outer peripheral front surface of the core member 7, it is possible to prevent the side portion 2b from being worn by the strong sliding contact with the front guide surface 26a.
In addition, as shown by the dotted line in FIG. 4, when the side portion 2 b of the sheet 2 is extended to the outside of the roller 22 to improve the airtightness, when the sheet portion facing the roller 22 is locally incised, Rolling contact of the roller 22 can be performed. When the roller 22 is provided on the core 7 that is directly inserted into the guide groove 26 without using the core support 9 as described above, the roller support shaft portion is inserted in the eccentric support direction with respect to the core 7. Then, it can be performed by a structure such as mounting and fixing.

次に図6を参照し可撓心材13側にセットされる最下心材支持具9aについて説明する。この最下心材支持具9aは前記心材支持具9と互換性を有するように同様な形状にすることが望ましく、取付部23と支持杆21を鉄製で形成し、支持杆21の先端に前記プラスッチック製のローラ22を軸支している。そして、実施形態による最下心材支持具9aは、可撓心材13が曲がった状態でさらに所定以上の曲げ負荷が掛かると、支持杆21が屈曲することができ、屈曲した支持杆21は曲げを修正することができる。
この構成により最下心材支持具9aは支持杆21が屈曲しても再使用することができ、且つ心材支持具9が破損したときにその予備が無い場合に、代替用品としても利用することができる。
Next, the lowermost core material support 9a set on the flexible core material 13 side will be described with reference to FIG. It is desirable that the lowermost core material support 9a has the same shape so as to be compatible with the core material support 9. The mounting portion 23 and the support rod 21 are made of iron, and the plastic hook is formed at the tip of the support rod 21. A roller 22 made of a metal is pivotally supported. The lowermost core material support 9a according to the embodiment can bend the support rod 21 when a bending load of a predetermined level or more is applied while the flexible core material 13 is bent, and the bent support rod 21 bends. It can be corrected.
With this configuration, the lowermost core material support 9a can be reused even if the support rod 21 is bent, and can be used as an alternative when there is no spare when the core material support 9 is damaged. it can.

さらに図示例の最下心材支持具9aは、前記心材支持具9と同様にローラ22を前側ガイド面26aに転接させる偏心位置に設けることもできるが、このローラ22はガイド溝26の中心部乃至は後側ガイド面26b側に転接するように位置決めしている。これにより、シート2の下端側のシート面をより前側ガイド面26a側に位置させることができる。
即ち、最下心材支持具9aは、前記心材支持具9と同様にローラ22を前側ガイド面26aに転接させる偏心位置に設けると、シート2の下端のシート面は後側ガイド面26b側に位置し、上方の心材支持具9側から下方後方に大きく後退傾斜した状態で進退作動するので、前側ガイド面26aとシート2の下端シート面との気密性を損なうことになる。特にシート2の下降時に上方の心材支持具9のローラ22が接地部11側の重量によって、後側ガイド面26b側に寄せられ前後に大きく揺れながら下降する等の課題を生ずるものである。
Further, in the illustrated example, the lowermost core material support 9a can be provided at an eccentric position where the roller 22 is brought into rolling contact with the front guide surface 26a in the same manner as the core material support 9, but the roller 22 is formed at the center of the guide groove 26. Or it positions so that it may roll-contact to the rear side guide surface 26b side. As a result, the seat surface on the lower end side of the seat 2 can be positioned closer to the front guide surface 26a.
That is, when the lowermost core material support 9a is provided at an eccentric position where the roller 22 is brought into rolling contact with the front guide surface 26a in the same manner as the core material support 9, the sheet surface at the lower end of the sheet 2 faces the rear guide surface 26b. Therefore, the airtightness between the front guide surface 26a and the lower end seat surface of the seat 2 is impaired. In particular, when the seat 2 is lowered, the roller 22 of the upper core material support 9 is moved toward the rear guide surface 26b due to the weight on the grounding portion 11 side, and causes a problem such that the roller 22 is lowered while swinging back and forth.

上記各ローラ22の位置決め固定は、心材支持具9の場合は図5に示すように、先鋭な取付ネジ27を心材取付部2aの外側から取付部23にねじ込むことにより、心材取付部2aと心材支持具9を心材7に共締めすることによって行われる。また最下心材支持具9aは取付ネジ28を、心材取付部12の外側から取付部23に形成したネジ穴29にねじ込むことにより、心材取付部12と可撓心材13を着脱自在に共締め固定することができる。尚、最下心材支持具9aは鉄製に限定することなく、心材支持具9より重量及び破断強度の大きい部材、例えばプラスッチック製の支持杆21内に可撓性を有する重量心材を一体的に挿入形成する等の手段で構成することもできる。   As shown in FIG. 5, in the case of the core material support 9, the rollers 22 are positioned and fixed by screwing a sharp mounting screw 27 into the mounting portion 23 from the outside of the core material mounting portion 2a. This is done by fastening the support 9 to the core material 7 together. Further, the lowermost core material support 9a is detachably fastened to the core material mounting portion 12 and the flexible core material 13 by screwing the mounting screws 28 into the screw holes 29 formed in the mounting portion 23 from the outside of the core material mounting portion 12. can do. The lowermost core material support 9a is not limited to iron, and a member having a larger weight and breaking strength than the core material support 9, for example, a plastic core material having flexibility is inserted into the support rod 21 made of plastic. It can also be configured by means such as forming.

上記構成によりシート2の下方は、可撓心材13をその両端に設けた最下心材支持具9aを支柱3のガイド溝26に挿入支持させた状態で、重錘心材7aは心材支持具類を省略して支柱3による直接的な支持をさせないで、接当緩衝間隔L及び心材支持幅Sに相当する側辺部2bのシート材によって支持させる。
これによりシート2は、図2の点線で示す可撓性経路Aを形成して、後述する心材上方退避作動並びに心材外し作動をスムーズに行なわせ、且つ同図の1点鎖線で示す剛性経路Bを形成し、シート2の下方部位の通直性を備えた開閉作動をスムーズに行うことができる。
With the above-described configuration, the weight core 7a is positioned below the seat 2 in a state where the lowermost core support 9a provided with the flexible core 13 at both ends thereof is inserted and supported in the guide grooves 26 of the support column 3. Omitted and not supported directly by the support columns 3, it is supported by the sheet material of the side portion 2 b corresponding to the contact buffer interval L and the core material support width S.
As a result, the sheet 2 forms a flexible path A indicated by a dotted line in FIG. 2 to smoothly perform a core material upward retraction operation and a core material removal operation described later, and a rigid path B indicated by a one-dot chain line in FIG. And the opening / closing operation with the straightness of the lower part of the seat 2 can be performed smoothly.

次に支柱3について説明する。建物等のゲート部材に組み付けられる一対の支柱3,3は、内向きに対向する内側壁の上下方向に開口部31を形成しており、この開口部31内にガイド溝26を有するガイドレール3aを着脱可能に取付固定している。そして、支柱3はガイド溝26内に、シート2の両側辺部2b,2b及び各心材支持具9、最下心材支持具9a等を挿入した状態で上下方向に移動案内し、シート2の昇降(進退作動)を行わせることができる。また支柱3内の空間部には、電気配線用のハーネス類や各種のボルトナット等の取付具並びに取付備品等が収容設置される。   Next, the column 3 will be described. A pair of columns 3 and 3 assembled to a gate member such as a building form an opening 31 in the vertical direction of the inner wall facing inward, and a guide rail 3a having a guide groove 26 in the opening 31. Is fixed detachably. The support column 3 is guided to move up and down in the guide groove 26 in a state where both side portions 2b and 2b of the seat 2 and each core material support 9 and the lowest core material support 9a are inserted. (Advance / retreat operation) can be performed. In addition, in the space portion in the support column 3, harnesses for electrical wiring, various fixtures such as bolts and nuts, fixtures, and the like are accommodated and installed.

上記ガイドレール3aは耐摩耗性を有するプラスッチック材により、前側ガイド面26aと後側ガイド面26bと内壁26cとを、平面視コの字状に一体的に成形してガイド溝26を形成している。このガイドレール3aは後側ガイド面26bの端部に沿って、ブラシ方式の気密保持部材32を着脱自在に設置する取付部33を凹入形成しており、該取付部33に気密保持部材32を設けることにより、シート2の下降閉鎖時にガイド溝26の開口をブラシ部材によって塞いだ状態にすることができる。   The guide rail 3a is formed of a plastic material having wear resistance, and the guide groove 26 is formed by integrally forming the front guide surface 26a, the rear guide surface 26b, and the inner wall 26c into a U-shape in plan view. Yes. The guide rail 3a has a mounting portion 33 in which a brush-type airtight holding member 32 is detachably installed along the end portion of the rear guide surface 26b. The airtight holding member 32 is provided in the mounting portion 33. By providing this, the opening of the guide groove 26 can be closed by the brush member when the seat 2 is lowered and closed.

図示例の気密保持部材32は、可撓性を有する多数の刷毛36を帯状の取付部材35に密植させて植立支持したブラシ構造とし、取付部材35を前記取付部33の一端から挿入し位置決めする簡潔な構成にしている。
これにより気密保持部材32としての刷毛36はガイド溝26を横断して前側ガイド面26a側に至り、閉鎖時のシート側辺部2bを背面から押接して前側ガイド面26aに接当させるように付勢する。
The airtight holding member 32 in the illustrated example has a brush structure in which a large number of flexible brushes 36 are closely planted on a belt-like attachment member 35 and supported by planting, and the attachment member 35 is inserted from one end of the attachment portion 33 and positioned. It has a simple structure.
As a result, the brush 36 as the airtight holding member 32 crosses the guide groove 26 and reaches the front guide surface 26a side, and presses the sheet side portion 2b when closed from the back surface so as to contact the front guide surface 26a. Energize.

そして、シート2が開閉作動する際に昇降する心材取付部2a等の突起物に接当する刷毛36は、これに倣って大きな抵抗となることなく屈曲退避したのち、突起物の通過に伴い弾力性によって元の植立姿勢に復帰し、シート2を押接した状態でガイド溝26を塞ぎ気密保持状態になる。   Then, the brush 36 that comes into contact with the protrusions such as the core member attachment portion 2a that moves up and down when the seat 2 is opened and closed is bent and retracted without causing a large resistance following the movement, and then the elasticity of the brush 36 with the passage of the protrusions. Returning to the original planting posture due to the nature, the guide groove 26 is closed in a state where the seat 2 is pressed and brought into an airtight holding state.

また刷毛36はシート2の側辺部2bを前側ガイド面26a側に付勢するので、前側ガイド面26aへのローラ22の転接を安定させると共に、閉鎖時に図5の点線で示すように側辺部2bを前側ガイド面26aに接当させ、シート2の前後方向に移動する大きな通気を防止し、シートシャッタ1の気密性を高めることができる。
尚、気密保持部材32は上記ブラシ方式のものに限定することなく、例えば刷毛36に代えて弾力性及び可撓性を有する膜体や、該膜体をシート2の開閉作動に伴い自動的に開閉させる等の構成にすることもできる。
Further, the brush 36 urges the side 2b of the sheet 2 toward the front guide surface 26a, so that the rolling contact of the roller 22 to the front guide surface 26a is stabilized and the side as shown by the dotted line in FIG. 5 when closed. The side part 2b is brought into contact with the front guide surface 26a, so that a large ventilation that moves in the front-rear direction of the seat 2 can be prevented, and the airtightness of the seat shutter 1 can be improved.
The airtight holding member 32 is not limited to the brush type described above. For example, instead of the brush 36, a film body having elasticity and flexibility, or the film body is automatically moved along with the opening / closing operation of the sheet 2. It can also be configured to open and close.

次にシート2の進退作動構造を図1を参照し説明する。このシートシャッタ1のモータ6は正逆回転可能なブレーキ付のモータを採用しており、モータ6のモータ軸はエンコーダー又はセンサ等の検出装置(不図示)を備え、検出したモータ6の回転数(信号)を制御ボックス37で読みとり判断し、シート2の作動及び停止を所望に行う。
またシートシャッタ1は、制御ボックス37に設けたリモコンスイッチ或いは設定スイッチ等の操作スイッチ類38によって、シート2の開閉動作並びに開閉パターン等のモード設定を自在に行い、シート2の進退移動を適正に行わせることができる。
Next, the advancing / retracting operation structure of the seat 2 will be described with reference to FIG. The motor 6 of the seat shutter 1 employs a motor with a brake that can rotate in the forward and reverse directions. The motor shaft of the motor 6 includes a detection device (not shown) such as an encoder or a sensor. (Signal) is read and judged by the control box 37, and the operation and stop of the seat 2 are performed as desired.
In addition, the seat shutter 1 can freely set the opening / closing operation of the seat 2 and the mode of the opening / closing pattern and the like by an operation switch 38 such as a remote control switch or a setting switch provided in the control box 37 to appropriately move the seat 2 forward and backward. Can be done.

そして、シートシャッタ1は、支柱3,3の高所部位に赤外線センサ等からなる開動センサ(起動センサ)39を正面側中央を向くように設置し、開動センサ39がシート2の前方に人や運搬車等の通過体を検出した際に、その検出信号によって制御ボックス37を介してモータ6を作動し閉鎖中のシート2を自動的に開くことができる。   The seat shutter 1 is provided with an opening sensor (starting sensor) 39 made of an infrared sensor or the like at a high part of the support columns 3 and 3 so as to face the center of the front side. When a passing body such as a transport vehicle is detected, the motor 6 can be operated via the control box 37 by the detection signal to automatically open the seat 2 being closed.

さらに、支柱3の下側にはシート2が開かれた状態で、該シート2の下方に障害物(接当物)があるとき、モータ6によるシート2の下降を規制する障害物検知用の赤外線或いは光電管等からなる下降規制センサ41を設置している。尚、前記接地部11に設置される図示しない下降停止センサの検知信号によって、モータ6を停止せしめ接当物とシート2を含むシートシャッタ1の損傷や接当トラブルの発生を防止することができる。   Further, when there is an obstacle (contacting object) below the seat 2 in a state where the seat 2 is opened on the lower side of the support post 3, an obstacle detection for restricting the lowering of the seat 2 by the motor 6 is performed. A lowering restriction sensor 41 made of infrared rays or a phototube is installed. Incidentally, the detection signal of a lowering stop sensor (not shown) installed in the grounding portion 11 can stop the motor 6 and prevent damage to the seat shutter 1 including the contact object and the seat 2 and occurrence of contact trouble. .

この停止信号は接地センサ43と接続する図示しない発信機器又は配線部材を介して制御ボックス37に送られる。これによりモータ6を停止させるか、又は制御ボックス37に設定された制御プログラムによって逆転させることにより、接当時にシート2の下降を即時停止又は上昇退避作動させることができる。   This stop signal is sent to the control box 37 via a transmitting device or a wiring member (not shown) connected to the ground sensor 43. As a result, the motor 6 is stopped or reversed by a control program set in the control box 37, so that the lowering of the seat 2 can be immediately stopped or lifted and retracted at the time of contact.

次に図1,図5,図6を参照し上記下降規制センサ41について説明する。このシートシャッタ1は一対の下降規制センサ41を支柱3,3の前側下部検出位置に設けたセンサ取付けカバー42の取付孔43に設け、且つ上方検出位置用の一対の下降規制センサ41を内側壁に直接的に設けている。この下降規制センサ41は図5,図6で示すように、取付ネジ45の挿入孔を有する取付座46に取付ガイド47を介し、センサ本体49を位置調節自在に取付支持する構成にしている。   Next, the lowering restriction sensor 41 will be described with reference to FIGS. The seat shutter 1 is provided with a pair of lowering restriction sensors 41 in an attachment hole 43 of a sensor attachment cover 42 provided at a front lower detection position of the columns 3 and 3, and a pair of lowering restriction sensors 41 for an upper detection position. Directly provided. As shown in FIGS. 5 and 6, the lowering restriction sensor 41 is configured to attach and support the sensor main body 49 so that the position of the sensor main body 49 can be adjusted via a mounting guide 47 on a mounting seat 46 having an insertion hole for a mounting screw 45.

即ち、センサ本体49は断面視コ字状の取付ガイド47に内嵌した状態で、取付ネジ51によって取付け位置調節自在とし、且つ取付ガイド47は取付座46に開設したセンサ孔52の上下に内向きに突設した取付片53,53に、取付ネジ55を介して位置調節自在に取付支持している。これにより下降規制センサ41は取付座46及び取付本体46を取付ネジによって、センサ取付けカバー42の取付孔43に取付けた状態で、上下左右の取付け位置(角度)調節を自在となし、適正センサ位置を速やかに設定すると共に簡単に組み付けることができる。   That is, the sensor main body 49 is fitted in a mounting guide 47 having a U-shaped cross-sectional view, and the mounting position can be adjusted by the mounting screw 51. The mounting guide 47 is mounted on the upper and lower sides of the sensor hole 52 provided in the mounting seat 46. The mounting pieces 53 and 53 projecting in the direction are mounted and supported via mounting screws 55 so that the position can be adjusted. As a result, the lowering restriction sensor 41 can freely adjust the mounting position (angle) of the upper, lower, left and right with the mounting seat 46 and the mounting body 46 mounted to the mounting hole 43 of the sensor mounting cover 42 with mounting screws. Can be set quickly and assembled easily.

以上のように構成されるシートシャッタ1は、巻取ドラム5の正逆回転によってシート2の巻取繰出動作による開閉作動を進退作動構造によってスムーズに行い、且つ接地部11及び気密保持部材32等の構成によって、シート2の閉鎖時の気密性を向上させることができる。そして、シート2の開閉時において、シート2の下降時に接地部11が上方から接当物に強く接当したとき、接地部11は接当負荷を先ず接地カバー16を介して緩衝部材17が受けたのち可撓心材13が受け、大きな負荷の場合には可撓心材13が上方に向けて弾力的に撓むことにより衝撃を緩衝する。   The sheet shutter 1 configured as described above smoothly opens and closes by the forward / backward operation structure of the sheet 2 by the forward / reverse rotation of the winding drum 5, and the grounding portion 11, the airtight holding member 32, and the like. With this configuration, the airtightness when the seat 2 is closed can be improved. When the seat 2 is opened and closed, when the grounding portion 11 comes into strong contact with the contact object from above when the seat 2 is lowered, the grounding portion 11 first receives the contact load via the ground cover 16 by the buffer member 17. After that, the flexible core material 13 receives, and in the case of a large load, the flexible core material 13 flexes upwards to cushion the impact.

然し接当負荷が継続される場合には、可撓心材13がシート2の下降と相俟って接当緩衝間隔Lのシート撓み代を超えて重錘心材7aに接当し、該重錘心材7aを上方に持ち上げるように作動させる。これにより接地部11は、接当緩衝間隔Lを介し剛性部材からなる重錘心材7aを上方に逃がす上方退避作動をさせるので、接当物及び接当物の損傷等を防止することができる。   However, when the contact load is continued, the flexible core member 13 contacts the weight core member 7a beyond the sheet bending allowance of the contact buffer interval L in combination with the lowering of the sheet 2, and the weight The core material 7a is operated to lift upward. As a result, the grounding portion 11 performs an upward retracting operation for releasing the weight core material 7a made of a rigid member upward through the contact buffering interval L, and thus the contact object and the contact object can be prevented from being damaged.

そして、接当負荷がさらに強く継続され可撓心材13及び重錘心材7aが、また心材7と共に左右に大きく傾いて下降する心材接当傾斜作動をするような場合には、先ず可撓心材13の最下心材支持具9aがガイドレール3aから抜け出して外れ、次いで心材7も心材支持具9を介してガイドレール3aから外すことができるので、この心材外し作動によって過大な接当トラブルを回避することができる。尚、このような接当トラブル時には在来のものと同様に、トラブル検出手段によってモータ6が逆転することによりシート2の下降をやめ反転(退避)上昇される。   When the contact load is further continued and the flexible core material 13 and the weight core material 7a perform a heart material contact inclination operation in which the core material 7 and the core material 7 are greatly inclined to the left and right, the flexible core material 13 is firstly operated. Since the lowermost core material support 9a comes out of the guide rail 3a and comes off, the core material 7 can also be removed from the guide rail 3a via the core material support 9, so that an excessive contact trouble is avoided by this operation of removing the core material. be able to. In the case of such a contact trouble, similarly to the conventional case, the motor 6 is reversely rotated by the trouble detecting means, so that the lowering (retreating) of the seat 2 is stopped.

このとき、接地部11内に設けた可撓心材13の上方に接当緩衝間隔Lを有して略平行状に設ける重錘心材7aは、ガイド溝26に挿入支持される複数の心材7及び可撓心材13より短くし、その両側をガイド溝26内に挿入させないで側辺部2bを挿入するシート2のガイド支持構造としているので、
図2の点線で示す可撓性経路Aを形成して、前記上方退避作動並びに心材外し作動をスムーズに行うと共に、同図の1点鎖線で示す剛性経路Bを形成し、シート2の下方部位の通直性を確保し強風等によるシート外れを防止した開閉作動をスムーズに行うことができるものである。
At this time, the weight core material 7a provided in a substantially parallel shape with a contact buffering interval L above the flexible core material 13 provided in the grounding portion 11 includes a plurality of core materials 7 inserted and supported in the guide grooves 26, and Since it is shorter than the flexible core 13 and has a guide support structure for the sheet 2 in which the side part 2b is inserted without inserting both sides into the guide groove 26,
A flexible path A shown by a dotted line in FIG. 2 is formed to smoothly perform the upward retracting operation and the core material removing operation, and a rigid path B shown by a one-dot chain line in FIG. Therefore, the opening / closing operation can be smoothly performed while ensuring the straightness of the sheet and preventing the sheet from being detached due to a strong wind or the like.

即ち、シート2の下方部位には、重錘心材7aの両側に形成される心材支持幅Sと接当緩衝間隔Lと可撓心材13等からなる可撓性経路Aを形成し、上下及び前後方向の可撓性を備えるので、例えば可撓心材13が心材接当傾斜作動した場合に、上向き傾斜する最下心材支持具9aは心材支持幅Sを有する側辺部2bを撓ませて重錘心材7aに接当しないので、重錘心材7aの持ち上げ抵抗を接当物に付加しない利点がある。また可撓心材13は最下心材支持具9aが上方の心材7に接当する間に十分に心材接当傾斜作動することができ、最下心材支持具9aをガイドレール3aから速やかに離脱させて、心材外し作動をスムーズに行わせることができる。   That is, in the lower part of the sheet 2, a flexible path A including a core support width S, a contact buffering interval L, a flexible core 13 and the like formed on both sides of the weight core 7a is formed. For example, when the flexible core material 13 is operated to tilt the core material, the lowermost core material support tool 9a that tilts upward deflects the side portion 2b having the core material support width S to be weighted. Since it does not contact the core material 7a, there is an advantage that the lifting resistance of the weight core material 7a is not added to the contact object. In addition, the flexible core 13 can sufficiently operate to tilt the core material while the lower core material support 9a contacts the upper core material 7, and the lower core material support 9a can be quickly detached from the guide rail 3a. Thus, the operation of removing the core material can be performed smoothly.

そして、上記のような作用を行う可撓性経路Aを有しながら、可撓心材13の両側に支持される最下心材支持具9aと、短い距離の接当緩衝間隔Lを有して可撓心材13の直上に支持される重錘心材7aとからなる剛性経路Bを形成していることにより、シート2の下方部位の通直性を確保し強風等による前後方向の負荷に対し、シート外れを防止した開閉作動をスムーズに行うことができる。またローラ22を備えた最下心材支持具9a,心材支持具9によって心材7及び可撓心材13を進退作動させるので、開閉作動時の摩擦抵抗を軽減し且つシート2の摺動を抑制した巻取繰出の高速化を図ることができる。またシートシャッタ1の建物への設置コストやメンテナンス作業コスト等を低減することができる。   And while having the flexible path | route A which performs the above operations, it is possible to have the lowermost core material support 9a supported on both sides of the flexible core material 13 and a short contact buffering interval L. By forming a rigid path B composed of the weight core material 7a supported immediately above the flexible core material 13, the straightness of the lower part of the seat 2 is ensured, and the seat against the load in the front-rear direction due to strong winds, etc. The opening / closing operation that prevents the disengagement can be performed smoothly. Further, since the core material 7 and the flexible core material 13 are moved forward and backward by the lowermost core material support 9a and the core material support 9 provided with the roller 22, the winding which reduces the frictional resistance during the opening and closing operation and suppresses the sliding of the seat 2. It is possible to speed up the delivery. Further, the installation cost of the seat shutter 1 in the building, the maintenance work cost, etc. can be reduced.

さらに、シート2は開閉作動時或いは接地した閉鎖時に、接当物が例えばシート2の接地部11に前方又は後方から強く接当した際には、接地部11が受ける横方向の接当負荷を先ず可撓心材13が受け、該可撓心材13が弾力的に撓むことにより衝撃を緩衝するが、接当負荷が強く継続される場合には、可撓性経路Aを介して両側の側辺部2bを撓み代として付加するので、可撓心材13を前後方向に十分に撓ませて緩衝すると共に、可撓心材13の変形破損を防止する。そして、重錘心材7aと可撓心材13の両側の最下心材支持具9aによる剛性経路Bによって、この際に受ける最下心材支持具9aのガイドレール3aからの無理な引抜き離脱を抑制し、接当負荷に対抗したのちはシート2の通直性を速やかに復元させることができる。   Further, when the seat 2 is opened / closed or closed upon grounding, when the contact object strongly touches the grounding portion 11 of the seat 2 from the front or rear, for example, a lateral contact load received by the grounding portion 11 is applied. First, the flexible core material 13 receives and shocks are buffered by the flexible core material 13 flexing elastically. However, when the contact load continues strongly, both sides of the flexible core material 13 are connected via the flexible path A. Since the side portion 2b is added as a bending allowance, the flexible core material 13 is sufficiently bent in the front-rear direction to be buffered, and deformation and damage of the flexible core material 13 are prevented. And, by the rigid path B by the lowermost core material support 9a on both sides of the weight core material 7a and the flexible core material 13, the unreasonable withdrawal from the guide rail 3a of the lowermost material support material 9a received at this time is suppressed, After countering the contact load, the straightness of the seat 2 can be quickly restored.

そして、可撓心材13或いは重錘心材7aの直上の心材7に対する局部的な接当負荷がさらに強く継続される場合には、前記重錘心材7aの側辺部2bの自由な撓みによって支持された状態で、最下心材支持具9a又心材支持具9はガイドレール3aから無理な姿勢をとることなく抜け出すことができる。従って、この際の最下心材支持具9aや心材支持具9及びガイドレール3aの変形や破損等は確実に防止される。   And when the local contact load with respect to the core material 7 just above the flexible core material 13 or the weight core material 7a continues further strongly, it is supported by the free bending of the side part 2b of the weight core material 7a. In this state, the lowermost core material support 9a or the core material support 9 can be removed from the guide rail 3a without taking an unreasonable posture. Accordingly, the lower core material support 9a, the core material support 9, and the guide rail 3a are reliably prevented from being deformed or damaged.

また重錘心材7aそのものが大きな前後方向負荷を受けたとしても、該重錘心材7aは心材支持具類を備えずに側辺部2bを介してガイド溝26に支持しているので、重錘心材7aは変形することなく側辺部2bの心材支持幅Sと接当緩衝間隔Lを介して前後動して負荷を緩衝し、且つシート2下方部の前後方向への大きな撓み(膨らみ)を阻止するので強風にも耐えることができる。   Even if the weight core material 7a itself is subjected to a large longitudinal load, the weight core material 7a is supported by the guide groove 26 via the side portion 2b without including the heart material support tools. The core material 7a moves back and forth through the core material support width S and the contact buffering interval L of the side portion 2b without deformation to buffer the load, and a large deflection (swelling) in the front-rear direction of the lower portion of the seat 2 occurs. Because it prevents it, it can withstand strong winds.

また上記のように構成した心材支持具9或いは最下心材支持具9a備えるシート2は、心材7が受ける負荷を心材7より弱い破断強度の心材支持具9で弾力的に受けさせるので、接当負荷等を緩衝し心材7の変形や破損等を防止し保護することができる。そして、変形又は破損をした心材支持具9或いは最下心材支持具9aは、組み立てとは逆順の作業によって取付ネジ27,28等による固定を解除すると、心材7等を外すことなく引き抜いて取り外すことができるので、心材支持具類の修理或いは交換を行ないメンテナンス作業を簡単に行うことができる。   Further, the sheet 2 provided with the core material support 9 or the lowermost core material support 9a configured as described above elastically receives the load received by the core material 7 with the core material support 9 having a breaking strength weaker than that of the core material 7. A load or the like can be buffered to prevent or protect the core material 7 from being deformed or damaged. Then, the deformed or damaged core material support 9 or the lowermost core material support 9a is pulled out and removed without removing the core material 7 etc. when the fixing by the mounting screws 27, 28, etc. is released by an operation reverse to the assembly. Therefore, the maintenance work can be easily performed by repairing or exchanging the core material support tools.
