Description

本発明は、折戸開閉機構における案内装置に係わり、更に詳しくはレール上を転動するローラにより吊下げ式で開閉する折戸を安定に開閉案内する装置に関するものである。   The present invention relates to a guide device in a folding door opening / closing mechanism, and more particularly to a device that stably opens and closes a folding door that opens and closes by a roller that rolls on a rail.

従来から、ヒンジで連結した二枚の戸先側パネルと戸尻側パネルを折畳んで開放したり、伸展して閉止したりする折戸は各種提供されている。特許文献１には、戸先側と戸尻側パネルのそれぞれの側部に横幅の狭い袖パネルをヒンジにて連結し、該袖パネルの上端部に設けたランナの４個の車輪を、断面略Ｃ字形レールの内部で両側ガイド溝の上を転動するように配置し、折戸の開閉時に前記袖パネルがレールに沿って直線的に移動する開閉機構が開示されている。ここで、前記ランナはレール内部に位置し、左右２個ずつの車輪がそれぞれレール内両側のガイド溝上を走行する構造であるので、脱輪することはないが、レールの構造やランナの構造が複雑になるばかりでなく、組立施工性に問題がある。   Conventionally, various types of folding doors have been provided in which two door-end side panels and a door-end side panel connected by hinges are folded and opened, or extended and closed. In Patent Document 1, a sleeve panel having a narrow width is connected to each side of a door-end side and a door-end side panel by a hinge, and four wheels of a runner provided at the upper end of the sleeve panel are cross-sectioned. There is disclosed an opening / closing mechanism that is arranged to roll on both side guide grooves inside a substantially C-shaped rail, and that the sleeve panel moves linearly along the rail when the folding door is opened / closed. Here, the runner is located inside the rail, and the left and right wheels each run on the guide grooves on both sides of the rail, so the wheel will not be removed, but the rail structure and runner structure Not only is it complicated, but there is a problem in assembly workability.

そこで、レールと車輪若しくはローラによる案内装置の構造を単純化するために、一本のレール上をローラが走行するように構成することが考慮されるが、ローラの脱輪や走行時の振れの問題が生じる。脱輪の問題については、特許文献２に示すように、吊り金具の上部に側設した溝付きローラをレールの上縁に載支するとともに、吊り金具の下部に取付位置を上下方向に微調節できる抑えローラを、レールの下縁に当接若しくは接近させて配置する構造が提案されている。また、特許文献３には、戸吊金に調整金を取付けた戸吊具を引戸の上端両側部に取付けて断面略Ｊ字形のレールに移動可能に吊下げる構造が開示され、前記調整金には上部にローラを側設するとともに、その下方に外れ防止用ローラを上下変位可能に設け、外れ防止用ローラを下降させた状態でローラを正面側からレールに載置した後、外れ防止用ローラを上動させてレールとの間隔を狭める構造が開示されている。   Therefore, in order to simplify the structure of the guide device using rails and wheels or rollers, it is considered that the rollers run on a single rail. Problems arise. As for the problem of derailment, as shown in Patent Document 2, a grooved roller provided on the upper side of the hanging bracket is mounted on the upper edge of the rail, and the mounting position is finely adjusted in the vertical direction below the hanging bracket. There has been proposed a structure in which a restraining roller that can be arranged is placed in contact with or close to the lower edge of the rail. Further, Patent Document 3 discloses a structure in which a door suspension with an adjustment metal attached to a door suspension is attached to both ends of the upper end of the sliding door and is movably suspended on a rail having a substantially J-shaped cross section. The side is provided with a roller on the upper side, and a detachment prevention roller is provided below the roller so that it can be displaced vertically. After the detachment prevention roller is lowered, the roller is placed on the rail from the front side, and then the detachment prevention roller. The structure which narrows the space | interval with a rail by moving up is disclosed.

特許文献２と特許文献３とも、外れ防止用ローラを上下変位させる構造として、座板の一方に回転軸を突設するとともに、他方に該回転軸に対して偏心させて取付軸を突設し、回転軸に外れ防止用ローラを回転可能に支持し、取付軸を調整金に形成した孔に貫通させてナットで締着する構造を採用し、取付軸を回転調節することにより外れ防止用ローラを上下変位させるのである。しかし、取付軸を固定しているナットが経年変化で弛み、座板が回転して外れ防止用ローラがレールから離れ、その機能を果たさなくなることも考えられる。また、走行時の振れの問題は、直列に２個のローラを設けることで、ある程度は改善するが、床面に案内レールが存在しない吊下げ式の折戸では、パネルの面外方向の横振れは防止できない。
特開平８−１６５８３９号公報 実公昭３２−１８２７号公報 特許第３３４７８４３号公報 In both Patent Document 2 and Patent Document 3, as a structure in which the detachment prevention roller is displaced vertically, a rotating shaft protrudes from one of the seat plates, and an attachment shaft protrudes eccentrically from the rotating shaft on the other. , The rotation prevention shaft is rotatably supported on the rotation shaft, the mounting shaft is passed through the hole formed in the adjustment metal, and the nut is fastened with a nut. Is displaced up and down. However, it is also conceivable that the nut fixing the mounting shaft loosens due to aging, the seat plate rotates and the disengagement prevention roller leaves the rail and does not perform its function. In addition, the problem of run-out during running can be improved to some extent by providing two rollers in series, but in the case of a hanging type folding door where there is no guide rail on the floor, the lateral run-out of the panel in the out-of-plane direction Cannot be prevented.

そして、前記袖パネル８の戸先側端部には軟質材料で作製した戸当り１５を取付けるととともに、表裏両面には引手１６，１６を突設している。一方、前記戸尻側パネル６の戸尻側端部には、上下端部を除き凹部１７を形成し、該凹部１７に軟質材料から作製したパッキン１８を装着し、前記戸尻側の側框３との間に仮に指を挟んでも怪我をしないようにしている。   A door stop 15 made of a soft material is attached to the end of the sleeve panel 8 on the door-end side, and handles 16 and 16 are provided on both front and back surfaces. On the other hand, the door bottom side end of the door bottom panel 6 is formed with a recess 17 except for the upper and lower ends, and a packing 18 made of a soft material is attached to the recess 17 so that the side wall on the door bottom side is attached. If you put your finger between 3 and 3, you will not be injured.

次に、前記折戸１の開閉機構を説明する。図１及び図２に示すように、前記上框４の内部にアルミ押出し型材からなるレール部材１９を間口全体にわたって横設し、該レール部材１９に一体形成した１条のレール２０に、前記袖パネル８の上端に設けた戸先側吊支体２１と、前記戸尻側パネル６の戸尻側端部上端に設けた戸尻側吊支体２２を用いて移動可能に吊下げる。   Next, the opening / closing mechanism of the folding door 1 will be described. As shown in FIGS. 1 and 2, a rail member 19 made of an aluminum extrusion mold material is laid across the entire front opening inside the upper collar 4, and a single rail 20 integrally formed with the rail member 19 is attached to the sleeve 20. The door-end side suspended support body 21 provided at the upper end of the panel 8 and the door-end side suspension support body 22 provided at the upper end of the door-end side end portion of the door-end side panel 6 are suspended movably.

そして、前記レール部材１９の戸先側端部に設けた定荷重ばね装置２３から繰り出されたワイヤー（図示せず）を戸先側吊支体２１に連結して、前記折戸１が伸展する方向、つまり閉じ方向に一定荷重で付勢している。また、前記戸先側吊支体２１には、水平な回転軸を有する回転ダンパー２４を設け、前記レール部材１９の戸先側と戸尻側の端部にレール２０に沿って並設したラック２５，２５と前記回転ダンパー２４がそれぞれ噛合するようになっている。前記戸先側のラック２５と回転ダンパー２４とは、折戸１の閉止直前から閉止するまでの動作を緩慢にする機能を果たし、一方、戸尻側のラック２５と回転ダンパー２４とは、開放状態の折戸１の閉止動作を遅らせる機能を果たし、車椅子に乗った人や点滴器具を押して移動する人が自らの操作で出入りする際に、通過のための余裕時間を確保するのである。 Then, a wire (not shown) fed from a constant load spring device 23 provided at the door end side end of the rail member 19 is connected to the door end side suspension support body 21 so that the folding door 1 extends. In other words, it is energized with a constant load in the closing direction. Further, the door leading end side hanging支体21 is provided with a rotary damper 24 having a horizontal axis of rotation, juxtaposed along the rail 20 to the end portion of the door leading side and the door trailing end side of the rail member 19 Rack 25, 25 and the rotary damper 24 is in the jar by meshing, respectively. The door-side rack 25 and the rotary damper 24 function to slow down the operation from immediately before the folding door 1 is closed until the door 1 is closed, while the door-side rack 25 and the rotary damper 24 are open. The function of delaying the closing operation of the folding door 1 is achieved, and when a person on a wheelchair or a person who moves by pushing an infusion device enters or exits by his / her own operation, an allowance time for passage is secured.

次に、本発明の折戸開閉機構における案内装置を更に詳しく説明する。前記折戸１は、戸先側パネル５と戸尻側パネル６とが中間連結体７で連結した部分を表裏一方へ屈曲するように動作することで開くことができるが、前記引手１６を持って袖パネル８をレール２０に沿って移動させるだけで、折戸１の屈曲動作を引き起こすためには付加的な機能が必要である。本実施形態では、折戸１の開放動作の直後には全体がレール２０に沿って直線運動し、それから戸先側パネル５を蹴り出し手段２６で面外方向へ蹴り出すとともに、戸尻側パネル６の戸尻側端部に設けた回動手段２７で開放方向に強制的に回動させるようにしている。 Next, the guide device in the folding door opening / closing mechanism of the present invention will be described in more detail. The folding door 1 can be opened by bending the portion where the door end side panel 5 and the door bottom side panel 6 are connected by the intermediate connecting body 7 to one side of the front and back, but with the handle 16 An additional function is required to cause the folding operation of the folding door 1 only by moving the sleeve panel 8 along the rail 20. In the present embodiment, immediately after the folding operation of the folding door 1, the whole moves linearly along the rail 20 , and then the door end side panel 5 is kicked out of the plane by the kicking means 26 and the door bottom side panel 6. The door is forcibly rotated in the opening direction by the rotating means 27 provided at the end of the door bottom.

具体的には、前記蹴り出し手段２６は、戸先側パネル５の左右中間部の上端に側設したピン２６Ａを上框４に設けたガイドブロック２６Ｂの傾斜面で摺動押出しする構造である。ここで、折戸１が閉止状態では、前記ピン２６Ａがガイドブロック２６Ｂに係合しているので、前記戸先側パネル５と戸尻側パネル６とに面外方向から力が加わっても横に振れることがなく、閉止状態が安定に維持される。   Specifically, the kick-out means 26 has a structure in which a pin 26A provided on the upper end of the left and right intermediate portion of the door-end side panel 5 is slid and extruded on an inclined surface of a guide block 26B provided on the upper collar 4. . Here, when the folding door 1 is in the closed state, the pin 26A is engaged with the guide block 26B. Therefore, even if a force is applied to the door-end side panel 5 and the door-end side panel 6 from the out-of-plane direction, The closed state is stably maintained without shaking.

また、前記回動手段２７は、平面視略扇形のカム歯車２７Ａを、その中心を前記戸尻側吊支体２２に対して戸尻側パネル６を回動可能に連結した回動中心に一致させて前記戸尻側パネル６に回動可能に連結する一方、該カム歯車２７Ａが噛合する短いラック２７Ｂを上框４に固定し、更に前記カム歯車２７Ａが一定の回転角度だけ回動するように規制するストッパー（図示せず）を戸尻側パネル６に設けて構成している。従って、折戸１が閉止状態から開き始めると、先ずカム歯車２７Ａがラック２７Ｂに噛合した状態で戸尻側パネル６に対して自由に回転し、その結果、該戸尻側パネル６はレール２０に沿った直線運動をし、その後ストッパーでカム歯車２７Ａの回転が規制されるが、引き続き該カム歯車２７Ａはラック２７Ｂで回転力が付与されるので、戸尻側パネル６と一体となって回転し、該戸尻側パネル６を強制的に回転させる。一旦、前記戸先側パネル５と戸尻側パネル６とが折れ曲がると、その後は軽い力でより開放する方向へ屈曲させることが可能となる。   Further, the rotating means 27 coincides with the center of rotation of the cam gear 27A having a substantially fan shape in plan view, the center of which is connected to the door-side suspension support 22 so as to be rotatable. The short rack 27B meshed with the cam gear 27A is fixed to the upper collar 4 while the cam gear 27A is rotated by a certain rotation angle. A stopper (not shown) is provided on the door-side panel 6 so as to restrict it. Therefore, when the folding door 1 starts to open from the closed state, first, the cam gear 27A is freely rotated with respect to the door-end side panel 6 in a state where the cam gear 27A is engaged with the rack 27B. The rotation of the cam gear 27A is then restricted by the stopper, but the cam gear 27A is continuously applied with the rotational force by the rack 27B, so that the cam gear 27A rotates integrally with the door-side panel 6. Then, the door bottom panel 6 is forcibly rotated. Once the door-end side panel 5 and the door-end side panel 6 are bent, it can be bent in a more open direction with a light force thereafter.

前記戸先側吊支体２１を図５〜図８に基づいて説明する。先ず、前記レール部材１９は、水平部１９Ａと垂直部１９Ｂとを有する断面の概略が略Ｌ字形であり、下部の水平部１９Ａの端縁に前記レール２０を立上げて形成するとともに、該水平部１９Ａの下面の後方寄り、つまりコーナー寄りに下方開放したガイド溝２８を形成し、また前記垂直部１９Ｂの上縁前面側に係合溝１９Ｃを形成している。ここで、前記係合溝１９Ｃは、前記定荷重ばね装置２３、ラック２５，２５を取付けるために利用している。前記ガイド溝２８は、前後壁面がレール面２８Ａ，２８Ａとなっており、後方側、つまりコーナー側のレール面２８Ａの縁部には前方へ突出した係合片２８Ｂを形成している。   The door-end-side suspension support body 21 will be described with reference to FIGS. First, the rail member 19 is substantially L-shaped in cross section having a horizontal portion 19A and a vertical portion 19B. The rail member 19 is formed by raising the rail 20 on the edge of the lower horizontal portion 19A, and A guide groove 28 opened downward toward the rear of the lower surface of the portion 19A, that is, near the corner is formed, and an engagement groove 19C is formed on the front surface side of the upper edge of the vertical portion 19B. Here, the engagement groove 19 </ b> C is used for attaching the constant load spring device 23 and the racks 25, 25. The front and rear wall surfaces of the guide groove 28 are rail surfaces 28A and 28A, and an engagement piece 28B protruding forward is formed at the edge of the rail surface 28A on the rear side, that is, the corner side.

そして、前記戸先側吊支体２１は、側面視略Ｌ字形の吊支金具２９と、大小二つのローラ３０，３１と、外れ防止部材３２とからなっている。前記吊支金具２９の垂直な基板３３の側面に大径のローラ３０を回転可能に軸着するとともに、小径のローラ３１をその回動軸３４を基板３３の形成した傾斜長孔３５に貫通し、ナット３６で回動軸３４に形成した螺軸に螺合して高さ調節可能に取付けている。そして、前記吊支金具２９の基板３３の下端に折曲形成した下板３７を前記袖パネル８の上端面にネジ止めして取付け、そして前記大小のローラ３０，３１を正面側から前記レール２０に載置する。この際に、前記袖パネル８が水平になるように、前記小径ローラ３１の高さを調節する。このように二つのローラ３０，３１をレール２０に直列に載置することにより、前記戸先側吊支体２１の左右の揺れは規制される。   The door-end side suspension support body 21 includes a substantially L-shaped suspension support fitting 29, two large and small rollers 30 and 31, and a detachment prevention member 32. A large-diameter roller 30 is rotatably attached to the side surface of the vertical substrate 33 of the suspension bracket 29, and the small-diameter roller 31 passes through the inclined long hole 35 formed with the substrate 33 through the rotation shaft 34. The nut 36 is screwed onto a screw shaft formed on the rotating shaft 34 so that the height can be adjusted. Then, a lower plate 37 bent at the lower end of the base plate 33 of the suspension bracket 29 is attached to the upper end surface of the sleeve panel 8 by screwing, and the large and small rollers 30 and 31 are attached to the rail 20 from the front side. Placed on. At this time, the height of the small diameter roller 31 is adjusted so that the sleeve panel 8 is horizontal. By placing the two rollers 30 and 31 in series on the rail 20 in this way, the left and right shaking of the door-end side suspension support body 21 is restricted.

尚、前記大小二つのローラ３０，３１を用いる代わりに、同じ大きさの二つのローラを傾動板に並設し、該傾動板を前記吊支金具２９の側面に水平な回動軸で枢着しても良い。この場合には、前記折戸１の重心バランスによって袖パネル８の姿勢が決定される。   Instead of using the two large and small rollers 30 and 31, two rollers of the same size are arranged side by side on the tilting plate, and the tilting plate is pivotally attached to the side surface of the hanging support bracket 29 with a horizontal rotating shaft. You may do it. In this case, the posture of the sleeve panel 8 is determined by the center of gravity balance of the folding door 1.

そして、前記外れ防止部材３２は、支持板３８の水平片３８Ａの上面両側部に、前記ガイド溝２８内を移動する走行部として、垂直な回転軸を備えた一対の補助ローラ３９，３９を突設し、水平片３８Ａの前縁に垂直片３８Ｂを有するものである。前記垂直片３８Ｂには二つの螺孔４０，４０を形成している。そして、前記吊支金具２９のローラ３０，３１をレール２０に載置した吊下げ状態で、前記外れ防止部材３２の補助ローラ３９，３９を斜め下方から前記レール部材１９のガイド溝２８内に挿入し、水平片３８Ａを水平に起して垂直片３８Ｂを前記基板３３の裏面に当接し、その状態でレール部材１９に沿ってスライド移動させ、該基板３３に開設した取付孔４１，４１と垂直片３８Ｂの螺孔４０，４０を位置合わせして、取付孔４１に前方からネジ４２を通して前記螺孔４０に螺合する。前記外れ防止部材３２の補助ローラ３９，３９は、前記ガイド溝２８の両レール面２８Ａ，２８Ａで案内されてレール２０に平行状態を保ち転動する。また、前記ガイド溝２８の係合片２８Ｂの存在により、前記支持板３８を前記吊支金具２９にネジ止めした後には、前記補助ローラ３９，３９がガイド溝２８内から脱落することがないのである。尚、前記レール部材１９は、前記上框４の内部に架設した横桟４３を介して水平に支持されている。   The detachment prevention member 32 projects a pair of auxiliary rollers 39, 39 each having a vertical rotation shaft as a running portion that moves in the guide groove 28 on both sides of the upper surface of the horizontal piece 38A of the support plate 38. And has a vertical piece 38B on the front edge of the horizontal piece 38A. Two screw holes 40 are formed in the vertical piece 38B. Then, the auxiliary rollers 39, 39 of the disengagement prevention member 32 are inserted into the guide groove 28 of the rail member 19 from obliquely below in a suspended state in which the rollers 30, 31 of the suspension bracket 29 are mounted on the rail 20. Then, the horizontal piece 38A is raised horizontally and the vertical piece 38B is brought into contact with the back surface of the substrate 33. In this state, the horizontal piece 38A is slid along the rail member 19 and is perpendicular to the mounting holes 41 and 41 formed in the substrate 33. The screw holes 40, 40 of the piece 38B are aligned and screwed into the screw hole 40 through the screw 42 from the front to the mounting hole 41. The auxiliary rollers 39, 39 of the detachment preventing member 32 are guided by both rail surfaces 28A, 28A of the guide groove 28 and roll while maintaining a parallel state with the rail 20. Further, due to the presence of the engagement piece 28B of the guide groove 28, the auxiliary rollers 39, 39 will not fall out of the guide groove 28 after the support plate 38 is screwed to the suspension bracket 29. is there. The rail member 19 is supported horizontally via a horizontal rail 43 installed inside the upper rod 4.

このように、前記戸先側吊支体２１は、直列に配した二つのローラ３０，３１がレール２０上を転動し、該レール２０の転動線から離れた後方位置で直列に配した二つの補助ローラ３９，３９がガイド溝２８内で転動するので、レール部材１９に対して前後左右及び捩れが規制された状態で安定に走行することができるのである。つまり、図８に示すように、前記レール２０の中心線（転動線）と、前記ガイド溝２８の位置が平面において前後にずれているので、折戸１を開放する際に、引手１６を持って横方向に力を加えた場合、前記袖パネル８には回転する方向にモーメントが作用するが、前記戸先側吊支体２１によってレール２０に沿って移動させることができるのである。尚、前記補助ローラ３９，３９の代わりに、ガイド溝２８の方向に延びた長尺のスライダー若しくは支持板３８の水平片３８Ａの上面両側部に突設した一対のスライダーでも同様な効果が得られるが、本実施形態のように補助ローラ３９を設ける方がスムーズな案内という点でより好ましい。 As described above, the door-end-side suspension support body 21 is arranged in series at the rear position away from the rolling line of the rail 20 with the two rollers 30 and 31 arranged in series rolling on the rail 20. Since the two auxiliary rollers 39, 39 roll in the guide groove 28, the auxiliary roller 39, 39 can travel stably with the front and rear, right and left and torsion restricted with respect to the rail member 19. That is, as shown in FIG. 8, since the center line (rolling line) of the rail 20 and the position of the guide groove 28 are shifted forward and backward in the plane, the handle 16 is held when the folding door 1 is opened. When a force is applied in the lateral direction, a moment acts on the sleeve panel 8 in the direction of rotation, but the sleeve panel 8 can be moved along the rail 20 by the door-end side suspension support body 21. The same effect can be obtained by using a long slider extending in the direction of the guide groove 28 or a pair of sliders protruding on both sides of the upper surface of the horizontal piece 38A of the support plate 38 instead of the auxiliary rollers 39. However, it is more preferable to provide the auxiliary roller 39 as in this embodiment in terms of smooth guidance.

また、前記戸尻側吊支体２２は、前記戸先側吊支体２１と基本的には同じ構成であるが、図９に示すように、側面視略Ｌ字形の吊支金具４４の基板４５に一つのローラ４６を回転可能に側設し、下板４７に垂直な吊支軸４８で前記戸尻側パネル６の端部上端に回転可能に吊下げている。そして、前記吊支軸４８には、前記回動手段２７を構成するカム歯車２７Ａを回転可能に外装している。尚、前記同様の外れ防止部材３２を用い、前記吊支金具４４の基板４５に形成した取付孔４９，４９を利用してネジ５０にて取付ける。   The door butt side suspension support body 22 has basically the same configuration as the door end side suspension support body 21, but as shown in FIG. One roller 46 is rotatably provided on the side 45, and is suspended from an upper end of the door-side panel 6 by a suspension shaft 48 perpendicular to the lower plate 47. A cam gear 27A constituting the rotation means 27 is rotatably mounted on the suspension support shaft 48. In addition, it attaches with the screw | thread 50 using the attachment holes 49 and 49 formed in the board | substrate 45 of the said suspension support metal fitting 44 using the same prevention member 32 as the above.

本発明に係る折戸開閉機構は、図１０に示した閉止状態から、前記引手１６を持ってレール２０に沿って前記袖パネル８を移動させると、前記戸先側パネル５と戸尻側パネル６とが中間連結体７を介して１８０°折れ曲がり、図１１に示すように、重なった状態で戸尻側の側框３から直角に突出する。前記折戸１の開放動作の終期に、前記戸先側パネル５と戸尻側パネル６が折り畳まれると同時に、側框３の下部に設けた水平な移動規制板５１の孔５２に、戸尻側パネル６の回動中心の下端に弾性的に突設したボール５３を受け入れるとともに、前記横桟４３の戸尻側端部に突設した移動規制板５４の係合部に前記吊支軸４８を受け入れてそれ以上の移動を規制する。   The folding door opening / closing mechanism according to the present invention moves the sleeve panel 8 along the rail 20 with the handle 16 from the closed state shown in FIG. Is bent 180 ° through the intermediate coupling body 7 and protrudes at right angles from the side edge 3 on the door butt side in an overlapped state as shown in FIG. At the end of the opening operation of the folding door 1, the door end side panel 5 and the door bottom side panel 6 are folded, and at the same time, in the hole 52 of the horizontal movement restricting plate 51 provided in the lower part of the side wall 3, The ball 53 elastically projected at the lower end of the center of rotation of the panel 6 is received, and the suspension support shaft 48 is attached to the engaging portion of the movement restricting plate 54 projecting from the end of the horizontal rail 43 at the door butt. Accept and restrict further movement.

前記戸尻側の側框３は、図１０〜図１２に示すように、前記折戸１が閉止動作時に直線移動するので、その移動量を考慮して余裕を持たせた形状となっており、戸袋枠を兼用しているのである。具体的には、前記側框３は、断面略Ｌ字形の概略形状であり、表裏一側部に前記レール２０に沿った目隠し壁部５５と、間口部の終端を形成する端面壁部５６とを有し、図１０及び図１２（ａ）に示した閉止状態で、前記目隠し壁部５５と戸尻側パネル６の端部は僅かの間隙を設けて前後に重なった状態となっている。そして、前記戸尻側パネル６の戸尻側端部の表側、即ち前記目隠し壁部５５とは反対側には、上下端部を除き凹部１７を形成し、該凹部１７に軟質材料から作製したパッキン１８を装着しているが、該パッキン１８はスチール製の端面５７よりも側方へ突出設定している。前記パッキン１８の端部と前記端面壁部５６との間には十分な広さの空間部Ｓが設定されている。この空間部Ｓは、不意に指を差し入れるのに十分な広さを有している。   As shown in FIGS. 10 to 12, the side edge 3 on the door bottom side has a shape with a margin in consideration of the amount of movement because the folding door 1 moves linearly during the closing operation. It also serves as a door pocket frame. Specifically, the side bar 3 has a schematic shape with a substantially L-shaped cross section, a blindfold wall 55 along the rail 20 on one side of the front and back sides, and an end face wall 56 that forms the end of the frontage In the closed state shown in FIGS. 10 and 12A, the blindfold wall 55 and the end of the door-side panel 6 are overlapped in the front-rear direction with a slight gap. And the recessed part 17 was formed in the front side of the door edge side edge part of the said door edge side panel 6, ie, the opposite side to the said blindfolded wall part 55 except for the upper and lower end parts, and this recessed part 17 was produced from the soft material. Although the packing 18 is mounted, the packing 18 is set so as to protrude from the end face 57 made of steel to the side. A sufficiently large space portion S is set between the end portion of the packing 18 and the end face wall portion 56. This space portion S is wide enough to insert a finger unexpectedly.

それから、折戸１を開き始めると、図１２（ｂ）に示すように、最初は直線移動だけであるが、途中から図１２（ｃ）、（ｄ）に示すように回転運動を伴いながら、パッキン１８の端部と前記端面壁部５６との間の空間部Ｓが狭まる。この時に、最も指詰めの危険性が高いが、前記パッキン１８が軟質材料で作製され、しかも前記戸尻側パネル６の端面５７よりも側方へ突出設定しているので、仮にこの空間部Ｓに指を挟んだとしても当該パッキン１８が変形して指を保護するのである。そして、最終的に、図１２（ｅ）に示すように折戸１が開放されると、前記端面壁部５６の上下端部に突設した弾性材料からなる緩衝部材５８，５８に戸尻側パネル６が当止される。   Then, when the folding door 1 starts to open, as shown in FIG. 12 (b), only the linear movement is initially performed, but the packing is performed while rotating as shown in FIGS. 12 (c) and 12 (d). A space portion S between the end portion 18 and the end wall portion 56 is narrowed. At this time, although there is the highest risk of finger stuffing, the packing 18 is made of a soft material and is set so as to protrude from the end face 57 of the door-side panel 6 to the side. Even if a finger is sandwiched between them, the packing 18 is deformed to protect the finger. Finally, when the folding door 1 is opened as shown in FIG. 12 (e), the door-butt side panel is placed on the cushioning members 58, 58 made of an elastic material protruding from the upper and lower ends of the end face wall portion 56. 6 is stopped.

ここで、前記パッキン１８は、前記凹部１７の側面にネジ止めするための金属製の保持板５９を合成ゴムや合成樹脂でインサート成形して一体化し、保持板５９から戸尻側パネル６の表面に沿って側方へ延び、それから後方へ延びた断面略Ｌ字状の緩衝部６０とからなっている。そして、仮に前記空間部Ｓに指を挟んでも、前記パッキン１８の緩衝部６０が容易に変形して凹部１７内に退避するので、指が怪我をする恐れがないのである。   Here, the packing 18 is integrally formed by insert-molding a metal holding plate 59 for screwing to the side surface of the concave portion 17 with synthetic rubber or synthetic resin, and from the holding plate 59 to the surface of the door bottom panel 6. And a buffer portion 60 having a substantially L-shaped cross section that extends laterally along the rear side and extends rearward. Even if a finger is sandwiched between the space portions S, the buffer portion 60 of the packing 18 is easily deformed and retracted into the recess 17, so that the finger is not injured.

また、図１０及び図１１に示すように、前記中間連結体７及び側部ヒンジ部９においても指詰め防止を図っている。つまり、前記閉塞部材１０の円柱部１０Ａあるいは前記袖パネル８の半円柱状部１３と、前記目地部材１２の突片１２Ａ，１２Ａとの間には僅かの隙間しか設定せず、折戸１の開閉時に常に一定の隙間を維持するので、指詰めの可能性は皆無である。尚、前記閉塞部材１０の円柱部１０Ａと連結部１０Ｂの間には、前記目地部材１２の突片１２Ａを受け入れるための逃し溝１０Ｃを形成している。ここで、前記連結部１０Ｂは、小径の円柱状として示したが、単に平板状の形状でも良い。   Further, as shown in FIGS. 10 and 11, the intermediate coupling body 7 and the side hinge portion 9 also prevent finger filling. That is, only a slight gap is set between the cylindrical portion 10A of the closing member 10 or the semi-cylindrical portion 13 of the sleeve panel 8 and the projecting pieces 12A and 12A of the joint member 12, and the folding door 1 is opened and closed. Sometimes a constant gap is always maintained, so there is no possibility of fingering. An escape groove 10 </ b> C for receiving the protruding piece 12 </ b> A of the joint member 12 is formed between the cylindrical portion 10 </ b> A and the connecting portion 10 </ b> B of the closing member 10. Here, although the connecting portion 10B is shown as a small-diameter columnar shape, it may be simply a flat plate shape.
