Description

本発明は、建造物の前後方向に通過可能な出入り口等の開口部に建て付けられる障害物検知手段を備えた建築用シャッター装置の技術分野に関するものである。 TECHNICAL FIELD The present invention relates to the technical field of construction shutter devices having obstacle detection means installed in an opening such as a doorway through which a building can pass in the longitudinal direction.

従来、建築用シャッター装置の障害物検知装置として、シャッターカーテンの最下端に上座板部を連結し、該上座板部に対して上下動自在な状態で下座板部を取り付け、該上座板部に対して下座板部が上動することを障害物検知作動とし、これを障害物検知センサが検知をする構成にしたものが提唱されている。
このような障害物検知装置では、該座板の前後幅はガイドレールにおけるレール溝の溝幅よりも幅広であるため、左右幅はシャッターカーテンの左右幅よりも幅狭のものとしてレール溝には入らないよう構成され、レール際やレール溝内における障害物検知をすることが難しい。そこで、下座板部に延長部材を、該下座板部の左右端から左右方向外方に向けて突出した状態で一体的に取り付けることで、延長部材がレール溝内にまで挿入された状態とし、レール溝内において障害物が該延長部材に当接すると、延長部材と共に下座板部が上動して、検知スイッチを作動させるようにしたものが知られている（例えば、特許文献１参照。）。
そしてこのものでは、上座板部に振れ止め部材が、左右端から左右方向外方に向けて突出した状態で一体的に取り付けられたものとして、該振れ止め部材をレール溝内に挿入された状態としている。この場合に、振れ止め部材の下面を開口させた冂字状のものとして構成し、下座板部の延長部材が障害物に当接して振れ止め部材に対して上動すると、該延長部材が振れ止め部材の開口から振れ止め部材内部に挿入すると共に、延長部材と共に上動した下座板部が障害物検知センサの検知作動をさせるようにしている。 Conventionally, as an obstacle detection device for a building shutter device, an upper plate portion is connected to the lowermost end of a shutter curtain, and a lower plate portion is attached to the upper plate portion so as to be vertically movable. A configuration has been proposed in which the movement of the lower seat plate is regarded as an obstacle detection operation, and this is detected by an obstacle detection sensor.
In such an obstacle detection device, since the front and back width of the seat plate is wider than the groove width of the rail groove in the guide rail, the left and right width is narrower than the left and right width of the shutter curtain. It is configured not to enter, and it is difficult to detect obstacles near the rail or in the rail groove. Therefore, by integrally attaching the extension member to the lower seat plate portion in a state of protruding outward in the left-right direction from the left and right ends of the lower seat plate portion, the extension member is inserted into the rail groove. However, when an obstacle comes into contact with the extension member in the rail groove, the lower seat plate portion moves upward together with the extension member to activate the detection switch (for example, Patent Document 1). reference.).
In this structure, the anti-vibration member is integrally attached to the upper seat plate portion in a state in which it protrudes outward in the left and right direction from the left and right ends, and the anti-vibration member is inserted into the rail groove. and In this case, the lower surface of the anti-vibration member is configured as a letter-shaped one with an opening, and when the extension member of the lower seat plate contacts an obstacle and moves upward with respect to the anti-vibration member, the extension member It is inserted into the anti-vibration member through the opening of the anti-vibration member, and the lower seat plate portion that moves upward together with the extension member causes the detection operation of the obstacle detection sensor.

特開平１０－１０２９４９号公報JP-A-10-102949

ところでこのような障害物検知装置において、振れ止め部材は、全閉時、床面に接地することもあるため強度的な点で考慮しなければならないが、前記従来の振れ止め部材は、下端縁を開口した冂字状となるように構成したものであるため強度が弱いものとなってしまい、延長部材やガイドレールと接触すると開口が開いてしまったり、変形したりするという惧れがあり、ここに本発明が解決せんとする課題があった。 By the way, in such an obstacle detection device, the anti-vibration member may contact the floor surface when fully closed, so it must be considered in terms of strength. Since it is configured to have a letter shape with an opening, the strength is weak, and there is a risk that the opening will open or be deformed when it comes into contact with the extension member or the guide rail. There was a problem to be solved by the present invention.

以下、本発明の第一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は前後方向に通過可能な開口部の開閉をするため設けられる建築用シャッター装置（建築用開閉装置）であって、該建築用シャッター装置１は、開口部の左右両側に設けられるガイドレール２、該ガイドレール２に上下（昇降）案内移動されることで開口部の開閉をするシャッターカーテン（開閉体）３、開口部の上端部に設けられ、シャッターカーテン３が巻装される巻取りドラム４、巻取りドラム４の正逆駆動をする電動式の開閉機５、開閉機５の駆動制御をする制御部６等の各種の部材装置を備えて構成されること等は何れも従来通りである。尚、前後の方向性についての定義は、開口部を通常に通過する方向を前後方向とし、開口部を基準として手前側を「前」、反対側（向こう側、手先側）を「後」と前後の定義を便宜上しているが、これに限定されないものであることは言うまでもない。 A first embodiment of the present invention will be described below with reference to the drawings. In the drawings, reference numeral 1 denotes an architectural shutter device (architectural opening/closing device) provided to open and close an opening through which passage can be passed in the longitudinal direction. The architectural shutter device 1 is provided on both the left and right sides of the opening. A guide rail 2, a shutter curtain (opening/closing body) 3 that opens and closes an opening by being guided up and down (elevating) by the guide rail 2, is provided at the upper end of the opening, and the shutter curtain 3 is wound. The winding drum 4, the electric opening/closing device 5 for driving the winding drum 4 in forward and reverse directions, and the control unit 6 for controlling the drive of the opening/closing device 5 are provided. It is the same as before. In addition, the definition of the directionality of the front and back is the direction in which the opening is normally passed, and the front side is "front" and the opposite side (the other side, the finger side) is "back". Although the definitions before and after are used for convenience, it goes without saying that they are not limited to these.

前後シャッターカーテン３の最下端部には、ガイドレール２の案内溝２ａには挿入しない長さに設定される左右方向に長い座板７が設けられるが、該座板７は、シャッターカーテン３の最下端スラット３ａに連結される（設けられる）上座板部８と、該上座板部８に対して上下動自在に設けられる下座板部９と、これら上下座板部８、９間に介装される中間検知部材１０と、上座板部８と中間検知部材１０とのあいだに配される状態で上座板部８に設けられる障害物検知センサ１１とを備えて構成されている。 At the lowermost end of the front and rear shutter curtains 3, there is provided a seat plate 7 which is long in the left-right direction and which is set to a length not to be inserted into the guide groove 2a of the guide rail 2. An upper seat plate portion 8 connected (provided) to the lowermost end slat 3a, a lower seat plate portion 9 provided to be vertically movable with respect to the upper seat plate portion 8, and an intermediate seat plate portion 8, 9 interposed between the upper and lower seat plate portions 8, 9. and an obstacle detection sensor 11 provided on the upper seat plate portion 8 in a state of being arranged between the upper seat plate portion 8 and the intermediate detection member 10 .

前記上座板部８は下側（下端縁部）が開口したものであって、天井側の上片部８ａと前後両側の側片部８ｂとを備えた冂形状に形成されるが、そのうちの上片部８ａは、本実施の形態では、上下方向を向いた前後の段差片部８ｃをあいだに介する状態で前後方向中央（中間）部位が高くなった第一上片部８ｄと、該第一上片部８ｄよりも低い状態で前後に配される第二上片部８ｅとを備えた凸形状に形成されるが、第一上片部８ｄの前後方向中央（中間）部位には上方に向けて連結片部８ｆが突設形成されている。そして上座板部８は、連結片部８ｆが最下端スラット３ａに締結金具であるボルト３ｂを介して固定されている。
さらに前記側片部８ｂは、第二上片部８ｅの前後方向外端縁から垂下状に設けられるが、該側片部８ｂの下端部には、前後方向に向けて水平状に突出する水平片部８ｇが突出形成されている。そして該水平片部８ｇのうち、反対側（対向する側）の側片部８ｂ側に向けて延出する部位は、後述するように下座板部９受止め係止するための係止受け部８ｈとなっている。 The upper seat plate portion 8 is open on the lower side (lower edge portion), and is formed in a truncated shape having an upper piece portion 8a on the ceiling side and side piece portions 8b on both front and rear sides. In the present embodiment, the upper piece portion 8a includes a first upper piece portion 8d whose center (intermediate) portion in the front-rear direction is raised with front and rear step pieces 8c facing in the vertical direction interposed therebetween; It is formed in a convex shape with a second upper piece portion 8e arranged in the front and rear in a state lower than the first upper piece portion 8d, but an upper part is located at the center (middle) portion in the front-rear direction of the first upper piece portion 8d. A connecting piece portion 8f is formed so as to protrude toward. The connecting piece 8f of the upper seat plate 8 is fixed to the lowermost slat 3a via a bolt 3b as a fastener.
Further, the side piece 8b is provided in a drooping manner from the outer edge of the second upper piece 8e in the front-rear direction, and the lower end of the side piece 8b horizontally protrudes in the front-rear direction. A piece 8g is formed to protrude. A portion of the horizontal piece 8g that extends toward the side piece 8b on the opposite side (opposing side) is a locking receiver for receiving and locking the lower seat plate portion 9, as will be described later. It becomes part 8h.

一方、下座板部９は、上側が開口したものであって、底側の下片部９ａと、該下片部９ａの前後方向両端縁から起立上に設けられる前後の側片部９ｂとを備えることで凹陥状に形成されたものであるが、側片部９ｂは、下片部９ａの前後両端縁部から立設する下側の第一側片部９ｃと、該第一側片部９ｃの上端部から前後方向内側に向くよう形成された段差片部９ｄと、該段差片部９ｄの前後方向内端部から上方に向けて形成された第二側片部９ｅと、該第二側片部９ｅの上端部から前後方向外方に向けて水平状に形成された上片部９ｆとを備えたものとして形成され、本実施の形態においては前後の第一側片部９ｃ間、及び第二側片部９ｅ間に上下方向に続く状態で凹陥状のスペースＳが形成されている。 On the other hand, the lower seat plate portion 9 is open on the upper side, and consists of a lower piece portion 9a on the bottom side and front and rear side piece portions 9b provided upwardly from both front and rear ends of the lower piece portion 9a. The side piece portion 9b includes a lower first side piece portion 9c erected from the front and rear end edges of the lower piece portion 9a, and the first side piece A stepped piece portion 9d formed so as to face inward in the front-rear direction from the upper end portion of the portion 9c, a second side piece portion 9e formed upward from the inner end portion in the front-rear direction of the stepped piece portion 9d, and the second side piece portion 9e. and an upper piece portion 9f formed horizontally outward in the front-rear direction from the upper end portion of the two side piece portions 9e. , and the second side piece 9e.

そして下座板部９は、前記上座板部係止受け部８ｈの前後方向内端に第二側片部９ｅが遊嵌状に（前後方向に間隙（隙間）を存する状態で）内嵌することにより、上片部９ｆが係止受け部８ｈの上面に係止する位置を下限とし、段差片部９ｄが係止受け片８ｈの下面に当接する位置を上限として上下移動自在に構成されているが、該下座板部９は、前後両上片部９ｆが上座板部８の前後両係止受け部８ｈに受止め係止された状態が自然の下動姿勢となっており、これによって上片部９ｆは、上座板部８に対して下座板部９を係止するための係止部を構成している。 In the lower seat plate portion 9, the second side piece portion 9e is loosely fitted (with a gap in the front-rear direction) to the inner end of the upper seat plate engagement receiving portion 8h in the front-rear direction. As a result, the upper piece 9f can move vertically with the lower limit being the position at which the upper piece 9f is engaged with the upper surface of the engagement receiving portion 8h, and the upper limit being the position at which the stepped piece 9d contacts the lower surface of the engagement receiving piece 8h. However, the lower seat plate portion 9 is naturally moved downward in a state in which both the front and rear upper pieces 9f are received and locked by the front and rear locking receiving portions 8h of the upper seat plate portion 8. Thus, the upper piece 9f constitutes a locking portion for locking the lower seat plate portion 9 to the upper seat plate portion 8. As shown in FIG.

そして、シャッターカーテン３が下降している開口部の閉鎖過程において、下座板部９に障害物が下側から当接することで、該下座板部９は上座板部８に対して上動する（持ち上げられる）ことになり、これを受けて中間検知部材１０が揺動して、障害物検知センサ１１が非検知状態から検知状態に切換わる（スイッチ切換えされる）ように設定されている。 In the closing process of the opening where the shutter curtain 3 is lowered, the lower seat plate portion 9 is moved upward with respect to the upper seat plate portion 8 by an obstacle coming into contact with the lower seat plate portion 9 from below. In response to this, the intermediate detection member 10 swings and the obstacle detection sensor 11 switches from the non-detection state to the detection state (is switched). .

次に、座板７の左右方向外端縁部分について説明する。
上座板部８の左右方向外端縁部は、該上座板部８の外端縁部と略同形状（凸形状）をした面部１２ａを有する上座板部カバー１２を取り付けることで塞がれている。該上座板部カバー１２は、面部１２ａから、上座板部８の側片部８ｂの内側に挿入される第一取付片部１２ｂと、該第一取付片部１２ｂの上端から内面側に向けてＬ字状に折曲形成され、第二上片部８ｅの内面側に挿入される第二取付片部１２ｃと、上座板部第一上片部８ｄの下面側に挿入される第三取付片部１２ｄとが左右方向内方に向けて延出形成されている。そして、各取付片部１２ｂ、１２ｃ、１２ｄを上座板部８内に挿入した状態で、第二取付片部１２ｃと上座板部第二上片部８ｅとを螺子１３によって螺子止め固定することで上座板部カバー１２は上座板部８に取り付けられる。 Next, the lateral outer edge portion of the seat plate 7 will be described.
The lateral outer edge of the upper seat plate portion 8 is closed by attaching an upper seat plate portion cover 12 having a surface portion 12a having substantially the same shape (convex shape) as the outer edge portion of the upper seat plate portion 8. there is The upper seat plate portion cover 12 includes a first mounting piece portion 12b inserted from the surface portion 12a into the inside of the side piece portion 8b of the upper seat plate portion 8, and an inner surface side from the upper end of the first mounting piece portion 12b. A second attachment piece portion 12c bent into an L shape and inserted into the inner surface side of the second upper piece portion 8e, and a third attachment piece inserted into the lower surface side of the upper seat plate portion first upper piece portion 8d. A portion 12d is formed to extend inward in the left-right direction. Then, with the mounting pieces 12b, 12c, and 12d inserted into the upper plate portion 8, the second mounting piece portion 12c and the upper plate portion second upper piece portion 8e are screwed and fixed with screws 13. The upper seat plate portion cover 12 is attached to the upper seat plate portion 8 .

The anti-vibration member 14 is formed by bending a metal plate material. A tubular portion 14d having a square tubular shape is formed by bending the side portion 14b and a pair of front and rear upper surface portions 14c facing inward in the front-rear direction from the upper edge of the side portion 14b. A mounting piece portion 14e is further bent upward from the inner edge of the upper surface portion 14c. The lowermost end slat 3a and the connecting piece 8f of the upper seat plate 8 are tightened together through the bolt 3b described above through a long hole 14g formed in the extension piece 14f, thereby preventing vibration. The member 14 is attached to the upper seat plate portion 8 .
Moreover, the bottom surface portion 14a is opened at its inner portion in the left-right direction, and an insertion portion 14h, which will be described later, is formed thereon. It has become.
A lower end edge portion of the portion corresponding to the insertion portion 14h of the side surface portion 14b is a folded portion 14k formed with a folded piece portion 14j that is folded back inward in the front-rear direction.

一方、下座板部９の左右方向外端縁は、側面視凸形状をした面材からなる下座板部カバー１６を取り付けることで塞がれている。該下座板部カバー１６は、下座板部９の上半側を塞ぐ上半部１６ａと下半部側を塞ぐ幅広の下半部１６ｂとを備えて構成されるが、上半部１６ａは、上下方向中間部に段差状部１６ｃを有して、上側の第一上半部１６ａ１、下側の第二上半部１６ａ２で構成されているが、下半部１６ｂと面一状の第二上半部１６ａ２から、該段差状部１６ｃを存して、下半部１６ｂに対して左右方向内側に偏倚した状態の第一上半部１６ａ１となっている。また、下半部１６ｂには、前後方向中央に位置して前後一対の切欠き部１６ｄが形成されており、該切欠き部１６ｄに後述するよう延長部材１７が下側から挿入される構成となっている。 On the other hand, the left-right outer edge of the lower seat plate portion 9 is closed by attaching a lower seat plate portion cover 16 made of a surface material having a convex shape when viewed from the side. The lower seat plate portion cover 16 includes an upper half portion 16a covering the upper half side of the lower seat plate portion 9 and a wide lower half portion 16b covering the lower half side. has a stepped portion 16c in the middle portion in the vertical direction, and is composed of a first upper half portion 16a1 on the upper side and a second upper half portion 16a2 on the lower side, but is flush with the lower half portion 16b. The second upper half portion 16a2 forms a first upper half portion 16a1 that is biased inward in the left-right direction with respect to the lower half portion 16b with the stepped portion 16c present. A pair of front and rear notch portions 16d are formed in the lower half portion 16b at the center in the front-rear direction. It's becoming

次に、延長部材１７について説明する。延長部材１７は延長部１７ａが左右方向外側に突出するよう形成されるが、該延長部１７ａは、前後一対の側面部１７ｂと底面部１７ｃとを備えることで上面が開口した凵字状に構成されている。そして、側面部１７ｂの左右方向内側端からは、それぞれ前後方向外方に向けてＬ字状に折曲された状態で延出する延出部１７ｄと、該延出部１７ｄからさらに左右方向内方に向けてＬ字状に折曲成形される係止部１７ｅとが形成されている。
そして、延長部材１７は、延長部１７ａの前後側面部１７ｂを下座板部カバー１６の切り欠き部１６ｄに挿入した状態で、延長部材１７の延出部１７ｄの左右方向外側面と下座板部カバー１６の左右方向内側面とを溶着等の固定手段を介して接合することで一体化されている。 Next, the extension member 17 will be explained. The extension member 17 is formed so that the extension portion 17a protrudes laterally outward, and the extension portion 17a is configured in a letter shape with an open upper surface by being provided with a pair of front and rear side portions 17b and a bottom portion 17c. It is An extension portion 17d extending outward in the front-rear direction in a state of being bent in an L-shape extends from the left-right direction inner end of the side surface portion 17b, and an extension portion 17d further extends in the left-right direction from the extension portion 17d. A locking portion 17e is formed which is bent in the L-shape toward one side.
The extension member 17 is configured such that the front and rear side portions 17b of the extension portion 17a are inserted into the notch portions 16d of the lower seat plate portion cover 16, and the left and right outer surfaces of the extension portion 17d of the extension member 17 and the lower seat plate are aligned. It is integrated with the left-right direction inner surface of the cover 16 by joining through fixing means such as welding.

このように下座板部カバー１６と一体化された延長部材１７は、係止部１７ｅが下座板部第一側片部９ｃ内に挿入された状態で、該係止部１７ｅと下座板部第一側片部９ｃとをリベット１８によって止め固定することで下座板部カバー１６と延長部材１７は下座板部９に取り付けられる。 The extension member 17 integrated with the lower seat plate portion cover 16 in this manner is configured such that the engaging portion 17e and the lower seat are connected in a state in which the engaging portion 17e is inserted into the lower seat plate portion first side piece portion 9c. The lower seat plate portion cover 16 and the extension member 17 are attached to the lower seat plate portion 9 by fixing and fixing the plate portion first side piece portion 9 c with the rivet 18 .

次に、座板７に、上座板部８には、上座板部カバー１２と振れ止め部材１４が、下座板部９には、下座板部カバー１６と延長部材１７がそれぞれ取り付けられた状態のシャッターカーテン３について、開閉作動におけるこれら部材の動きについて説明する。
まず、シャッターカーテン３の全開時において、図９（Ａ）、図１０（Ａ）、図１１（Ａ）に示すように、振れ止め部材１４の下端縁部である底面部１４ａと延長部材側面部１７ｂの上端縁部とのあいだは、下座板部９が上座板部８に対して垂下しているため、隙間Ｓ１を存した状態となっている。また、振れ止め部材嵌入部１４ｈの左右長さは、延長部材延長部１７ａの左右長さよりも長いものとして設定されると共に、振れ止め部材１４は、延長部材延長部１７ａと共にガイドレール案内溝２ａ内に挿入されている。
この状態から閉鎖方向へシャッターカーテン３を下降させたとき、延長部材底面部１７ｃに障害物が当接すると、図１１（Ｂ）に示すように、延長部材１７は下座板部９と共に上座板部８に対して上動し始める。このとき、該延長部材の延長部１７ａは、振れ止め部材嵌入部１４ｈ内に嵌入することになると共に、下座板部カバー１６の第一上半部１６ａ１は、段差状部１６ｃによって左右方向内方に偏倚しているため、上座板部カバー１２にガイドされながら、下座板部カバー上半部１６ａは該上座板部カバー面部１２ａの内面に挿入されることになる。
そして、図９（Ｂ）、図１０（Ｂ）、図１１（Ｃ）に示すように、下座板部９が上座板部８に対して上動し終わると、延長部材１７の下端縁部である底面部１７ｃは、振れ止め部材の下端縁部である底面部１４ａ（連結部１４ｉ）と面一状となるように構成されている。
このとき、振れ止め部材１４は床面と当接することになるが、側面部１４ｂの下端縁は折返し片部１４ｊが折曲形成された折曲部１４ｋとなっているため、シャッターカーテン３を上下動させたときに、該下端縁部位がガイドレール案内溝２ａ内で引っ掛かることなくスムーズに上下動することができ、しかも、該下端縁部位の強度を確保することができるように構成されている。 Next, the upper seat plate portion cover 12 and the anti-vibration member 14 were attached to the seat plate 7, the upper seat plate portion 8, and the lower seat plate portion cover 16 and the extension member 17 were attached to the lower seat plate portion 9, respectively. The movement of these members in the opening and closing operation of the shutter curtain 3 in the state will be described.
First, when the shutter curtain 3 is fully open, as shown in FIGS. Since the lower seat plate portion 9 hangs down from the upper seat plate portion 8, a gap S1 exists between the upper end edge portion of 17b. Further, the lateral length of the anti-vibration member fitting portion 14h is set to be longer than the lateral length of the extension member extension portion 17a, and the anti-vibration member 14 is positioned inside the guide rail guide groove 2a together with the extension member extension portion 17a. is inserted in the
When the shutter curtain 3 is lowered in the closing direction from this state, if an obstacle comes into contact with the extension member bottom surface portion 17c, the extension member 17 and the lower seat plate portion 9 move toward the upper seat plate as shown in FIG. 11(B). Begin to move up against part 8 . At this time, the extension portion 17a of the extension member is fitted into the anti-vibration member fitting portion 14h, and the first upper half portion 16a1 of the lower seat plate portion cover 16 is laterally inward by the stepped portion 16c. Since the lower seat plate cover upper half 16a is guided by the upper seat plate cover 12, the lower seat plate cover upper half 16a is inserted into the inner surface of the upper seat plate cover surface portion 12a.
Then, as shown in FIGS. 9B, 10B, and 11C, when the lower seat plate portion 9 finishes moving upward with respect to the upper seat plate portion 8, the lower end edge portion of the extension member 17 is reached. The bottom surface portion 17c is configured to be flush with the bottom surface portion 14a (connecting portion 14i) that is the lower edge portion of the anti-vibration member.
At this time, the anti-vibration member 14 comes into contact with the floor surface, but since the lower edge of the side surface portion 14b is a bent portion 14k formed by bending the folded piece portion 14j, the shutter curtain 3 can be moved up and down. When moved, the lower edge portion can move up and down smoothly without being caught in the guide rail guide groove 2a, and the strength of the lower edge portion can be ensured. .

なお、下座板部９が障害物に当接した場合についても、同様に延長部材の延長部１７ａが振れ止め部材１４の内部に進入する。
また、シャッターカーテン３が全閉して下座板部９並びに延長部１７ａが床面に当接した場合も、同様に延長部材の延長部１７ａが振れ止め部材１４の嵌入部ｈに進入し、全閉となったときに延長部材１７の下端縁部である底面部１７ｃは、振れ止め部材の下端縁部である底面部１４ａ（連結部１４ｉ）と面一状となるように構成されている点も同様である。 Also when the lower seat plate portion 9 comes into contact with an obstacle, the extension portion 17a of the extension member similarly enters the anti-vibration member 14 .
Also, when the shutter curtain 3 is fully closed and the lower seat plate portion 9 and the extension portion 17a are in contact with the floor surface, the extension portion 17a of the extension member similarly enters the fitting portion h of the anti-vibration member 14, The bottom surface portion 17c, which is the lower edge portion of the extension member 17, is configured to be flush with the bottom surface portion 14a (connecting portion 14i), which is the lower edge portion of the anti-vibration member, when the extension member 17 is fully closed. The same applies to points.

一方、図９（Ｂ）、図１０（Ｂ）、図１１（Ｃ）に示す全閉状態のシャッターカーテン３が上昇して開放状態となる場合、シャッターカーテン３の上昇に伴って上座板部８が上昇するが（図１１（Ｂ））、下座板部９は上座板部９に対して相対的に下動して、上座板部８に対して垂下した状態となる（図９（Ａ）、図１０（Ａ）、図１１（Ａ））。このとき、延長部材１７は、延長部１７ａが振れ止め部材嵌入部１４ｈから下方向に抜け出ることとなり、振れ止め部材１４の下端縁部である底面部１４ａと延長部材側面部１７ｂの上端縁部とのあいだに隙間Ｓ１を存した状態となる。
このように、延長部材嵌入部１４ｈは、延長部材延長部１７ａが上下方向に出入り自在に嵌入するものとして構成されていて、延長部材１７が振れ止め部材１４に対して上動すると延長部１７ａは上動して振れ止め部材嵌入部１４ｈ内に嵌入し、下動すると延長部材嵌入部１４ｈから抜け出るように構成されている。 On the other hand, when the shutter curtain 3 in the fully closed state shown in FIGS. rises (FIG. 11(B)), but the lower seat plate portion 9 moves downward relative to the upper seat plate portion 9 and hangs down with respect to the upper seat plate portion 8 (see FIG. 9(A ), FIGS. 10(A) and 11(A)). At this time, the extension portion 17a of the extension member 17 is pulled out downward from the anti-vibration member fitting portion 14h, and the bottom surface portion 14a, which is the lower end edge portion of the anti-vibration member 14, and the upper end edge portion of the extension member side portion 17b. A gap S1 exists between them.
In this way, the extension member fitting portion 14h is configured so that the extension member extension portion 17a can be inserted in and out of the vertical direction. It is configured to move upward to fit into the anti-vibration member fitting portion 14h, and to move downward to come out of the extension member fitting portion 14h.

叙述のごとく本発明が実施された第一の実施の形態において、振れ止め部材１４は、延長部材１７よりも左右方向外方に向けて長くなっていて、延長部材１７と共にガイドレール案内溝２ａに挿入するものであって、該振れ止め部材１４は、延長部材１７が上下方向に出入り自在に嵌入する嵌入部１４ｈと、該嵌入部１４ｈの左右方向外側において前後方向に連結された連結部１４ｉとを備えている。よって、延長部材１７の左右方向外方に、振れ止め部材連結部１４ｉが備えられているため、延長部材１７が嵌入するべく底面が開口した嵌入部１４ｈが設けられているものでありながら、振れ止め部材１４の強度が十分なものとなる。そして、ガイドレール案内溝２ａ内に振れ止め部材１４と延長部材１７が挿入されることで、ガイドレール際やガイドレール案内溝２ａ内における障害物検知も確実に行うことができる。 As described above, in the first embodiment in which the present invention is carried out, the anti-vibration member 14 is longer than the extension member 17 toward the left-right direction outward, and is aligned with the extension member 17 in the guide rail guide groove 2a. The anti-vibration member 14 includes a fitting portion 14h into which the extension member 17 can be inserted in the vertical direction, and a connecting portion 14i connected in the front-rear direction outside the fitting portion 14h in the left-right direction. It has Therefore, since the anti-vibration member connecting portion 14i is provided outside the extension member 17 in the left-right direction, the insertion portion 14h having an open bottom surface for the extension member 17 to be inserted therein is provided. The strength of the stop member 14 becomes sufficient. By inserting the anti-vibration member 14 and the extension member 17 into the guide rail guide groove 2a, it is possible to reliably detect obstacles near the guide rail and in the guide rail guide groove 2a.

また、振れ止め部材１４の下端縁部（底面部１４ａ）と延長部材延長部１７ａの上端縁部との間には、隙間Ｓ１が設けられているため、下座板部９と延長部材１７が障害物に当接して、傾斜した状態で上動したような場合であっても、抵抗にならずにスムーズに延長部材１７が振れ止め部材嵌入部１４ｈ内に進入することができる。
さらに、下座板部９が上座板部８に対して上動した状態では、振れ止め部材１４の底面部１４ａと、延長部材底面部１７ｃとが面一状になるため、前記隙間Ｓ１を塞いだ状態とすることができる。
さらにまた、振れ止め部材嵌入部１４ｈの下端縁部には、前後方向内側に向いた折返し片部１４ｊが形成されており、これによって、シャッターカーテン３を上下動させたときに、該下端縁部位がガイドレール案内溝２ａ内で引っ掛かることなくスムーズに上下動することができ、しかも、該嵌入部１４ｈを含めた振れ止め部材１４の強度を確保することができる。 In addition, since a gap S1 is provided between the lower edge portion (bottom surface portion 14a) of the anti-vibration member 14 and the upper edge portion of the extension member extension portion 17a, the lower seat plate portion 9 and the extension member 17 are separated from each other. Even if the extension member 17 contacts an obstacle and moves upward in an inclined state, the extension member 17 can smoothly enter the anti-vibration member fitting portion 14h without causing resistance.
Furthermore, when the lower seat plate portion 9 is moved upward with respect to the upper seat plate portion 8, the bottom surface portion 14a of the anti-vibration member 14 and the extension member bottom surface portion 17c are flush with each other, closing the gap S1. state.
Furthermore, a folded piece portion 14j facing inward in the front-rear direction is formed at the lower edge portion of the anti-vibration member fitting portion 14h. can move up and down smoothly without being caught in the guide rail guide groove 2a, and the strength of the anti-vibration member 14 including the fitting portion 14h can be ensured.

また、延長部材１７には、下座板部９の左右方向外端縁を塞ぐ下座板部カバー１６が一体に形成されているため、設置時における部品点数を削減することができる。
さらに、前記上座板部８の左右方向外端縁部には、該外端縁部を塞ぐ上座板部カバー１２が設けられ、前記下座板部カバー１６には、下座板部９が上動するとき上座板部カバー１２の内側に入り込むよう段差状部１６ｃが形成されている。これにより、上下座板部８、９の左右方向の位置ズレを規制することができると共に、前記段差状部１６ｃによって下座板部９の上動がスムーズに案内されることになる。
さらにまた、延長部材１７は、閉鎖時に床面に当接したり、障害物に当接したりするものであるため、強度が必要となるが、本実施の形態の延長部材延長部１７ａは、上面が開口した断面凵字状に形成されることにより強度が十分に確保されたものとなっている。 In addition, since the extension member 17 is integrally formed with the lower seat plate portion cover 16 that closes the left-right outer edge of the lower seat plate portion 9, the number of parts at the time of installation can be reduced.
Furthermore, an upper seat plate portion cover 12 is provided at the lateral outer edge portion of the upper seat plate portion 8 to close the outer edge portion. A stepped portion 16c is formed so as to enter the inside of the upper seat plate portion cover 12 when it moves. As a result, positional deviation of the upper and lower seat plate portions 8, 9 in the left-right direction can be regulated, and the upward movement of the lower seat plate portion 9 can be smoothly guided by the stepped portion 16c.
Furthermore, since the extension member 17 abuts on the floor or an obstacle when closed, it requires strength. Sufficient strength is ensured by forming an open cross-sectional shape.

尚、本発明は前記実施の形態に限定されるものでないことは勿論であって、振れ止め部材の形状を図１２、１３に示す第二の実施の形態の振れ止め部材２０のようにすることもできる。
該振れ止め部材２０は、第一の実施の形態と金属製の板材を折曲して形成したものであって、一枚状の板材を、左右外側端面部２０ａと、該左右外側端面部２０ａの前後両端から左右方向内側に延出する一対の側面部２０ｂと、該側面部２０ｂの上端縁から前後方向内方に向いた前後一対の上面部２０ｃと、該上面部２０ｃの内端縁から上方に向けて取付片部２０ｄと、側面部２０ｂの下端縁部は、前後方向内側に向けて折り返される折返し片部２０ｅとが折曲形成されているが、さらに一方の取付片部２０ｄの左右方向内側には長孔２０ｇが形成される延長片部２０ｆが面一状に形成されている。そして、本実施の形態において、左右外端面部２０ａが連結部の役割を果たしている。
このものにおいて、下座板部カバーは第一の実施の形態のものと同様の下座板部カバー１６を用いることができ、延長部材についても同様のものを用いることもできるが、延長部２１ａを左右外側端面部２０ａ位置まで延長させた延長部材２１とすることができる。このようにすることで、ガイドレール案内溝２ａの深い部分まで延長部材２１が挿入されることになって、より深い部分まで障害物検知をすることが可能となる。 The present invention is of course not limited to the above-described embodiment, and the shape of the anti-vibration member may be the anti-vibration member 20 of the second embodiment shown in FIGS. can also

An extension piece 20f in which a long hole 20g is formed is formed flush with the direction inner side. Further, in the present embodiment, the left and right outer end surface portions 20a serve as connecting portions.
In this embodiment, the same lower seat plate cover 16 as in the first embodiment can be used as the lower seat plate cover, and the same extension member can be used, but the extension portion 21a can be used. can be an extension member 21 extending to the left and right outer end surface portions 20a. By doing so, the extension member 21 is inserted into the deep portion of the guide rail guide groove 2a, and it becomes possible to detect the obstacle to a deeper portion.

また、参考例として示す図１４のように、パイプ式のシャッター装置の座板３０において、同様に上座板部３１、下座板部３２としたものについても、第一の実施の形態の上座板部カバー１２、下座板部カバー１６と延長部材１７を一体化したもの、を用いることができる。一方、このものにおいて、振れ止め部材３３は、嵌入部を備えず、下座板部３２が上座板部３１に対して上動した場合において、延長部１７ａの上端縁部と振れ止め部材３３の底面部３３ａとが対向した状態となるよう構成することができる。 Further, as shown in FIG. 14, which is shown as a reference example, in the seat plate 30 of the pipe-type shutter device, the upper seat plate portion 31 and the lower seat plate portion 32 are formed in the same manner as the upper seat plate of the first embodiment. It is possible to use a part cover 12, a bottom plate part cover 16 and an extension member 17 integrated with each other. On the other hand, in this device, the anti-vibration member 33 does not have an insertion portion, and when the lower seat plate portion 32 moves upward with respect to the upper seat plate portion 31, the upper end edge portion of the extension portion 17a and the anti-vibration member 33 It can be configured such that it faces the bottom surface portion 33a.
