In particular, when the folding door is closed, the space between the end faces of the door plate shrinks, and if there are fingers or the like between the end faces, it is conceivable that fingers will be sandwiched between the end faces (finger clogging). Covers for such gaps and spaces, and a device for preventing finger clogging have been proposed.

例えば、下記特許文献1では、二枚の扉の端部間の隙間を覆うカバーを設け、このカバーの内側に設けられたカバースライダを、二枚の扉を連結する蝶番に設けた扉スライダに支持させた構造とされた折戸の隙間カバー装置が提案されている。
また、下記特許文献2では、左右戸体の隙間をふさぐ形状の遮蔽カバーを設け、この遮蔽カバーを支持する連結棒を、二本の開脚バネを介して蝶番の取付部に取り付けた構造とされた折戸の指詰め防止装置が提案されている。
For example, in Patent Document 1 below, a cover that covers a gap between the ends of two doors is provided, and a cover slider provided inside the cover is used as a door slider provided on a hinge connecting the two doors. A folding door gap cover device having a supported structure has been proposed.
Further, in Patent Document 2 below, a structure is provided in which a shielding cover having a shape that closes the gap between the left and right doors is provided, and a connecting rod that supports the shielding cover is attached to a hinge attachment portion via two leg springs. An anti-finger device for folding doors has been proposed.

An insertion portion 38 is provided as an overlapping portion to be overlapped. On the other hand, as shown in FIG. 3A, a stopper insertion hole 35 through which the fixed stopper S is inserted is provided at the end (the upper end in the example) on the side different from the hinge 19. .
The insertion portion 38 can be inserted into the back surface side of the attachment piece connecting portion side end portion 19c of the hinge 19 (the side facing the back surface 12 of the door plate 10) with the hinge 19 fixed to the back surface 12 of the door plate 10. It is formed as thin as possible. Further, the insertion portion 38 is provided with a cutout portion 39 that opens toward the hinge 19 side. The notch 39 receives the fixing stopper S inserted through the insertion hole provided in the attachment piece connecting portion side end 19c of the hinge 19 when the insertion portion 38 is inserted into the back side of the hinge 19. The insertion portion 38 is vertically long so that it can be inserted to a fixed position.

また、取付プレート34の挿し込み部38の基端部(図例では上端部)表面側には、リブ状に形成された位置決め突条37が設けられている。この位置決め突条37は、蝶番19の取付プレート34側の端部(図例では、上端部)の端面19dの形状に対応させた形状とされ、挿し込み部38を蝶番19の裏面側に挿し込む際に、位置合わせ及びストッパーとして機能する。
なお、挿し込み部38を含み、当該取付プレート34は、厚さが0.1mm〜2.0mm程度に、比較的、薄く平板状に形成されている。
また、この取付プレート34の裏面(戸板10の裏面12に対面する側)には、図3(b)に示すように、戸板10の裏面12に圧入される位置決め突起が複数個所(図例では、二箇所)に設けられている。

And the whole becomes a structure accommodated in the space between the back surfaces 12 and 12 of each doorplate 10 and 10. FIG. That is, in the state in which the folding door 1 is fully opened, the space between the back surfaces 12 and 12 of the door plates 10 and 10 is narrow, but the entire mounting support portion 30 is accommodated in the narrow space as described above. Therefore, the fully open state of the folding door 1 is not disturbed by the finger plugging prevention device 2.

次に、蝶番19によって連結された戸板10,10の連結部11への指詰防止具2の組み付け工程の一例について、図3及び図4を参照して説明する。
取付支持部30の連結支持片31を、各戸板10,10の端面13,13間の隙間に、前後に挿通した状態で、一対の取付プレート34,34を、各戸板10,10の裏面12,12に配置する。
次いで、各取付プレート34,34の挿し込み部38,38を、蝶番19の取付片連結部側端部19c,19cの裏面側にそれぞれ挿し込み、各挿し込み部38,38と、蝶番19の各取付片連結部側端部19c,19cとを重ね合わせる。
この際、取付片連結部側端部19cの挿通孔に挿通された固定止具Sを、挿し込み部38の切欠部39に受け入れさせるようにして、固定止具Sをガイドにして蝶番19の裏面側、つまり、戸板10の裏面12と、蝶番19の裏面との間に挿し込む。また、この際、取付プレート34の表面側に設けられた位置決め突条37が蝶番19の取付プレート34側の端部の端面19dに当接するまで挿し込むことで、当該取付プレート34が、所定の固定位置に位置決めされる。
Next, an example of the assembly process of the finger clogging prevention tool 2 to the connection part 11 of the door plates 10 and 10 connected by the hinge 19 will be described with reference to FIGS. 3 and 4.
In a state where the connection support piece 31 of the attachment support part 30 is inserted in the gap between the end faces 13 and 13 of the door plates 10 and 10 in the front-rear direction, the pair of attachment plates 34 and 34 are connected to the back surface 12 of the door plates 10 and 10. , 12.
Next, the insertion portions 38 and 38 of the attachment plates 34 and 34 are respectively inserted into the back surfaces of the attachment piece connecting portion side end portions 19c and 19c of the hinge 19, and the insertion portions 38 and 38, Each attachment piece connection part side edge part 19c, 19c is piled up.
At this time, the fixing stopper S inserted through the insertion hole of the attachment piece connecting portion side end 19c is received by the notch 39 of the insertion portion 38, and the fixing stopper S is used as a guide to guide the hinge 19 It is inserted between the back side, that is, the back side 12 of the door plate 10 and the back side of the hinge 19. At this time, the positioning protrusion 37 provided on the front surface side of the mounting plate 34 is inserted until it comes into contact with the end surface 19d of the end portion of the hinge 19 on the mounting plate 34 side. Positioned at a fixed position.

つまり、切欠部39によって、当該取付プレート34の幅方向(戸板10の幅方向と同方向)の位置決めが可能となり、位置決め突条37によって、当該取付プレート34の上下方向(戸板10の上下方向と同方向)の位置決めが可能となる。
なお、挿し込み部38を挿し込む際に、その挿し込みを容易とするために、蝶番19の取付プレート34側の取付片(図例では上側)の挿通孔に挿通された固定止具Sを、仮止め状態としておき、取付プレート34を位置決めした後に、本締めするようにしてもよい。
That is, the notch portion 39 enables positioning of the mounting plate 34 in the width direction (the same direction as the width direction of the door plate 10), and the positioning protrusion 37 allows the mounting plate 34 to move in the vertical direction (the vertical direction of the door plate 10). Positioning in the same direction is possible.
In addition, when inserting the insertion part 38, in order to make the insertion easy, the fixed fastener S inserted in the insertion hole of the attachment piece (upper side in the illustrated example) on the attachment plate 34 side of the hinge 19 is inserted. Alternatively, it may be in a temporarily fixed state, and after the mounting plate 34 is positioned, the final fastening may be performed.

上記のように、取付プレート34の位置決めがなされれば、取付プレート34の上端部に設けられた止具挿通孔35に、固定止具Sを挿通し、戸板10の裏面12に止着することで、取付プレート34が、戸板10の裏面12に固定される(図1参照)。
次いで、図4に示すように、取付支持部30が取り付けられた状態で、折戸1を開状態として、連結支持片31の前端部に形成された係止爪部31a,31aと指詰防止カバー体20(カバー本体21)の後面側に形成された係止凹部22,22とを係合させる。これら係止爪部31a,31aは、左右に二股に分岐された前端部に形成されているので、その左右方向に沿う弾性変形を伴って容易に係合させることができる。
As described above, when the mounting plate 34 is positioned, the fixed stopper S is inserted into the stopper insertion hole 35 provided at the upper end portion of the mounting plate 34 and is fixed to the back surface 12 of the door plate 10. Thus, the mounting plate 34 is fixed to the back surface 12 of the door plate 10 (see FIG. 1).
Next, as shown in FIG. 4, with the attachment support part 30 attached, the folding door 1 is opened, and the locking claw parts 31 a and 31 a formed on the front end part of the connection support piece 31 and the finger clogging prevention cover The engagement recesses 22 and 22 formed on the rear surface side of the body 20 (cover body 21) are engaged. Since these latching claw portions 31a and 31a are formed at the front end portion bifurcated to the left and right, they can be easily engaged with elastic deformation along the left-right direction.

上記構成とされた指詰防止具2によれば、戸板10,10を連結する蝶番19と、当該指詰防止具2の取付支持部30とを、それぞれの一部を重ね合わせ、その重ね合わせ部位38,38,19c,19cを、共通の固定止具Sを用いて固定することができる。従って、蝶番19と、指詰防止具2の取付支持部30とを個別に固定するようなものと比べて、固定止具Sの本数を削減できる。また、いずれか一方を固定部位に対して位置合わせすれば、他方を重ね合わせて固定することができるので、位置合わせが容易となり、作業性を向上させることができる。
また、蝶番19には、指詰防止カバー体20を支持させるための支持部等を設ける必要がなく、蝶番の構造を、指詰防止具を装着するために複雑化させることがない。
According to the finger clogging prevention device 2 having the above-described configuration, the hinge 19 that connects the door plates 10 and 10 and the attachment support portion 30 of the finger clogging prevention device 2 are partially overlapped and overlapped. The parts 38, 38, 19c, 19c can be fixed by using a common fixing stopper S. Therefore, the number of the fixing stoppers S can be reduced as compared with the case in which the hinge 19 and the attachment support part 30 of the finger clogging prevention device 2 are individually fixed. Further, if any one of them is aligned with the fixing part, the other can be overlapped and fixed, so that the alignment becomes easy and the workability can be improved.
Further, the hinge 19 does not need to be provided with a support portion or the like for supporting the finger-clogging prevention cover body 20, and the hinge structure is not complicated because the finger-clogging prevention tool is attached.

また、本実施形態では、取付支持部30の取付プレート34に、固定止具S及び蝶番19の端面19dに対して位置合わせするための位置決め部としての切欠部39及び位置決め突条37を設けている。従って、戸板10の裏面12に固定された蝶番19に対して、取付プレート34の位置合わせを、より容易に行うことができ、より作業性を向上させることができる。
さらに、本実施形態では、取付支持部30の取付プレート34は、重ね合わせ部位として、戸板10に固定された蝶番19の裏面側に挿し込まれる挿し込み部38を有し、また、この挿し込み部38に切欠部39を設けている。従って、戸板10を蝶番19によって連結した後、取付プレート34の挿し込み部38を蝶番19の裏面側に挿し込み、固定することができる。この結果、例えば、指詰防止具2を装着しない折戸と、指詰防止具2を装着させる折戸とを製造する際に、製造ラインの一部を共用でき、生産性を向上させることができる。
In the present embodiment, the mounting plate 34 of the mounting support 30 is provided with a notch 39 and positioning ridges 37 as positioning portions for positioning with respect to the fixing stopper S and the end surface 19d of the hinge 19. Yes. Accordingly, the mounting plate 34 can be more easily aligned with the hinge 19 fixed to the back surface 12 of the door plate 10, and workability can be further improved.
Furthermore, in this embodiment, the attachment plate 34 of the attachment support part 30 has the insertion part 38 inserted in the back surface side of the hinge 19 fixed to the doorplate 10 as an overlapping part, and this insertion The part 38 is provided with a notch 39. Therefore, after the door plate 10 is connected by the hinge 19, the insertion portion 38 of the mounting plate 34 can be inserted and fixed to the back side of the hinge 19. As a result, for example, when manufacturing a folding door that is not equipped with the antifouling tool 2 and a folding door that is equipped with the antifouling tool 2, a part of the production line can be shared, and productivity can be improved.

さらにまた、上記構成とされた指詰防止具2によれば、蝶番19を正確に位置合わせしておけば、一対の取付プレート34,34を、戸板10,10の各端面13,13から均等位置となるように各戸板10,10の裏面12,12に、容易に固定することができる。
また、取付支持部30の一対のリンク状部材32,32は、略同寸同形状とされており、その戸板側枢軸32aから支持片側枢軸32bまでの長さが、それぞれ同寸法とされている。従って、上記のように取付プレート34,34を均等位置となるように、各戸板10,10の裏面12,12に固定することで、連結支持片31の位置決めを容易に行うことができる。つまり、連結支持片31が左右に位置ずれすることなく、戸板10,10の端面13,13間の隙間の中心に位置するように、当該取付支持部30を容易に取り付けることができる。
Furthermore, according to the finger clogging prevention tool 2 having the above-described configuration, if the hinge 19 is accurately aligned, the pair of mounting plates 34 and 34 are evenly spaced from the end surfaces 13 and 13 of the door plates 10 and 10. It can be easily fixed to the rear surfaces 12 and 12 of the door plates 10 and 10 so as to be positioned.
The pair of link-like members 32, 32 of the mounting support portion 30 are substantially the same size and the length from the door plate side pivot 32a to the support piece side pivot 32b is the same. . Therefore, the connection support piece 31 can be easily positioned by fixing the mounting plates 34 and 34 to the back surfaces 12 and 12 of the door plates 10 and 10 so as to be in an equal position as described above. That is, the attachment support part 30 can be easily attached so that the connection support piece 31 is positioned at the center of the gap between the end faces 13 and 13 of the door plates 10 and 10 without being displaced in the right and left direction.

さらに、本実施形態では、取付支持部30の連結支持片31の前端部及び指詰防止カバー体20の後面側には、互いに前後方向に係合する係合部としての係止爪部31a,31a及び係止凹部22,22がそれぞれ設けられている。従って、戸板10,10に固定された取付支持部30に対して、指詰防止カバー体20を容易に取付固定することができる。
なお、上記組み付け工程は、一例であり、別の手順でなされるようにしてもよい。
また、図例では、取付プレート34を強固に取付固定すべく、蝶番19の上側に固定した例を示しているが、逆側、つまり、蝶番19の下側に固定するようにしてもよい。
さらに、蝶番19の個数に応じて、それぞれの蝶番19に取付プレート34を重ね合わせて取付支持部30を固定し、これに加えて、蝶番19が設けられていない適所にも、取付支持部30を固定するようにしてもよい。
Further, in the present embodiment, on the front end portion of the connection support piece 31 of the attachment support portion 30 and the rear surface side of the finger plug prevention cover body 20, locking claws 31a as engagement portions that engage with each other in the front-rear direction. 31a and locking recesses 22 and 22 are provided, respectively. Therefore, the finger plug prevention cover body 20 can be easily attached and fixed to the attachment support portion 30 fixed to the door plates 10 and 10.
In addition, the said assembly | attachment process is an example and may be made by another procedure.
In addition, in the illustrated example, the attachment plate 34 is fixed on the upper side of the hinge 19 in order to firmly attach and fix it, but may be fixed on the opposite side, that is, on the lower side of the hinge 19.
Further, according to the number of the hinges 19, the attachment plate 34 is overlapped on each hinge 19 to fix the attachment support portion 30, and in addition to this, the attachment support portion 30 is also provided at an appropriate place where the hinge 19 is not provided. May be fixed.

次に、上記構成とされた指詰防止具2が装着された折戸1における指詰防止構造について、図2、図5及び図6に基づいて説明する。
なお、図5及び図6では、キャップ33の図示を省略している。
図2に示すように、折戸1が全開された状態から把手をして折戸1をスライドさせて、折戸1の閉動がなされる際には、図5(a)、(b)及び図6(a)に示すように、開き角θが大きくなるに伴って、一対のリンク状部材32,32が徐々に展開される。つまり、折り畳み状態とされた一対のリンク状部材32,32が、支持片側枢軸32b,32bを支点として回動し、互いのなす角が徐々に大きくなり、徐々に展開される。
この一対のリンク状部材32,32の展開動作に伴って、連結支持片31が連結支点19aに対して、手前側に向けて移動する。
Next, the finger-clogging prevention structure in the folding door 1 to which the finger-clog prevention tool 2 having the above-described configuration is mounted will be described with reference to FIGS. 2, 5, and 6.
5 and 6, the cap 33 is not shown.
As shown in FIG. 2, when the folding door 1 is slid by sliding the folding door 1 from the fully opened state and the folding door 1 is closed, FIGS. 5 (a), 5 (b) and 6. As shown to (a), a pair of link-shaped members 32 and 32 are expand | deployed gradually as opening angle (theta) becomes large. That is, the pair of link-like members 32, 32 in a folded state rotate with the support piece side pivots 32b, 32b as fulcrums, and the angles formed by each other gradually increase and gradually expand.
The connection support piece 31 moves toward the front side with respect to the connection fulcrum 19a in accordance with the unfolding operation of the pair of link members 32, 32.

つまり、これら一対のリンク状部材32,32と、各戸板10,10とが、拡縮されるパンタグラフ機構を構成するようにして、各戸板10,10の開き角θが大きくなるに伴って、一対のリンク状部材32,32が折り畳まれた状態から展開動作をなす。この展開動作によって、一対のリンク状部材32,32の各支持片側枢軸32b,32bが連結支点19aに向けて近接移動する。また、この動作に伴って、一対のリンク状部材32,32の各支持片側枢軸32b,32bに連結された連結支持片31が連結支点19aに対して前方に向けて押し出されるように移動する。この連結支持片31の前方への移動によって、その前端部に連結された指詰防止カバー体20が、戸板10,10の各端面13,13間に形成される扇状の空間を前方に向けて移動、つまり、連結支点19aに対して離反移動する。   That is, the pair of link-like members 32 and 32 and the door plates 10 and 10 constitute a pantograph mechanism that expands and contracts, and the pair of the door plates 10 and 10 become larger as the opening angle θ increases. The link-like members 32, 32 are expanded from the folded state. By this unfolding operation, the support piece side pivots 32b and 32b of the pair of link-like members 32 and 32 are moved close to each other toward the connection fulcrum 19a. With this operation, the connection support piece 31 connected to the support piece side pivots 32b, 32b of the pair of link members 32, 32 moves so as to be pushed forward with respect to the connection fulcrum 19a. The forward movement of the connection support piece 31 causes the finger-clogging prevention cover body 20 connected to the front end portion thereof to face the fan-shaped space formed between the end faces 13 and 13 of the door plates 10 and 10 forward. Move, that is, move away from the connection fulcrum 19a.

上記のように、扇状の空間を前方に向けて移動する指詰防止カバー体20の後面側(上記テーパ面部及び上記緩衝部)と、閉動に伴い互いに近接する戸板10,10の各端面13,13及び面取り部14,14とは、所定のクリアランスを隔てて、近接対面するようにして、相対的に移動する。なお、当該折戸1の開閉動作の態様(例えば、乱暴な開閉動作など)によっては、指詰防止カバー体20に揺動等が生じ、所定のクリアランスを隔てた安定的な移動がなされずに、指詰防止カバー体20が戸板10,10の端面13,13に当接、接触し、振動による異音が生じる場合がある。このような場合にも、本実施形態では、指詰防止カバー体20の緩衝部材24,24によって、衝突や振動により生じる恐れのある異音や損傷等を低減することができる。   As described above, the rear surface side (the tapered surface portion and the buffering portion) of the finger-clogging prevention cover body 20 that moves forward in the fan-shaped space, and the end surfaces 13 of the door plates 10 and 10 that are close to each other with the closing movement. , 13 and the chamfered portions 14, 14 move relative to each other so as to face each other with a predetermined clearance therebetween. Depending on the mode of opening / closing operation of the folding door 1 (for example, rough opening / closing operation, etc.), the finger clogging prevention cover body 20 may swing and the stable movement with a predetermined clearance is not performed. The finger plugging prevention cover body 20 may come into contact with and contact the end faces 13 and 13 of the door plates 10 and 10, and abnormal noise may be generated due to vibration. Even in such a case, in the present embodiment, the buffer members 24 and 24 of the finger plug prevention cover body 20 can reduce abnormal noise or damage that may occur due to collision or vibration.

上記のような折戸1の閉動に伴って、各戸板10,10の連結部11側の各端面13,13間に形成される扇状の空間は、徐々に小さくなるが、上記のように指詰防止カバー体20もそれに伴って、取付支持部30によって前方に向けて移動させられる。従って、これら各端面13,13及び面取り部14,14と指詰防止カバー体20の後面側とは、上述のように、原則的には所定のクリアランスを保持するようにして、近接対面して相対的に移動しながら、その閉動がなされる。
上記所定のクリアランスは、各端面13,13及び面取り部14,14と指詰防止カバー体20とが、上記のように原則的に相対移動する際に、当接しない程度以上、かつ、少なくとも押圧閉動の可能な状態から閉動がなされる際に手指等の挿入がなされない程度以下とすればよい。例えば、押圧閉動の可能な状態から閉動がなされる際のクリアランスが、0.2mm〜3.0mm程度となるようにしてもよい。
As the folding door 1 is closed as described above, the fan-shaped space formed between the end faces 13 and 13 on the connecting portion 11 side of the door plates 10 and 10 gradually decreases. Accordingly, the anti-clogging cover body 20 is also moved forward by the attachment support portion 30. Therefore, the end faces 13 and 13 and the chamfered portions 14 and 14 and the rear surface side of the finger clogging prevention cover body 20 face each other so as to keep a predetermined clearance in principle as described above. The closing is performed while moving relatively.
The predetermined clearance is greater than or equal to the extent that the end faces 13 and 13 and the chamfered portions 14 and 14 and the finger clogging prevention cover body 20 do not come into contact with each other in principle as a relative movement as described above. What is necessary is just to be below the extent that a finger or the like is not inserted when closing is performed from a state where the closing is possible. For example, the clearance when closing is performed from a state where pressing and closing is possible may be about 0.2 mm to 3.0 mm.

一方、図6(b)に示すように、閉止状態とされた折戸1を、開放させる際には、折戸1に設けられた把手等を、手前側に引き、スライドさせることで開動がなされる。
この折戸1の開動作がなされる際には、その開動作に伴って、上記した閉動作とは逆に、一対のリンク状部材32,32の折り畳み動作がなされる。
すなわち、各戸板10,10の連結支点19aを中心とする折り畳み動作に伴って、これら戸板10,10の裏面12,12に固定された取付プレート34,34の軸受部36,36に、それぞれの戸板側枢軸32a,32aが枢支された一対のリンク状部材32,32が折り畳まれる。
この一対のリンク状部材32,32が折り畳まれることによって、支持片側枢軸32b,32bに連結された連結支持片31が連結支点19aに対して後方に向けて引き込まれるように移動する。これにより、連結支持片31の前端部に連結された指詰防止カバー体20が、各端面13,13間に形成される扇状の空間を後方に向けて移動、すなわち、連結支点19aに対して近接移動する。
On the other hand, as shown in FIG. 6 (b), when the folding door 1 in the closed state is opened, the handle provided on the folding door 1 is pulled to the near side and slid to open. .
When the folding door 1 is opened, the pair of link-like members 32 and 32 are folded together with the opening operation, contrary to the above-described closing operation.
That is, with the folding operation centering on the connecting fulcrum 19a of each door plate 10, 10, the bearing portions 36, 36 of the mounting plates 34, 34 fixed to the back surfaces 12, 12 of the door plates 10, 10 A pair of link-like members 32 and 32 on which the door plate side pivots 32a and 32a are pivotally supported are folded.
When the pair of link-like members 32 and 32 are folded, the connection support piece 31 connected to the support piece side pivots 32b and 32b moves so as to be pulled backward with respect to the connection fulcrum 19a. Thereby, the finger clogging prevention cover body 20 connected to the front end portion of the connection support piece 31 moves rearward in the fan-shaped space formed between the end faces 13 and 13, that is, with respect to the connection fulcrum 19a. Move close.

以上のように、本実施形態に係る指詰防止具2を装着した折戸1によれば、指詰防止カバー体20によって指詰を防止することができる。つまり、折戸1の閉動がなされる際に、戸板10,10の連結部11側の各端面13,13間にて縮小する扇状の空間に手指が存在している場合にも、指詰防止カバー体20は、その空間を連結支点19aに対して前方に向けて移動する。従って、手指が該空間から指詰防止カバー体20によって、はじき出されるようにして、指詰の防止がなされる。   As described above, according to the folding door 1 equipped with the finger plug preventing tool 2 according to the present embodiment, the finger plug can be prevented by the finger plug preventing cover body 20. That is, when the folding door 1 is closed, even when fingers are present in a fan-shaped space that shrinks between the end faces 13 and 13 on the connecting portion 11 side of the door plates 10 and 10, finger clogging is prevented. The cover body 20 moves forward in the space with respect to the connection fulcrum 19a. Therefore, finger clogging is prevented by allowing the fingers to be ejected from the space by the finger clogging prevention cover body 20.

また、本実施形態では、指詰防止カバー体20の後面側と、戸板10,10の各端面13,13及び面取り部14,14とは、少なくとも当該折戸1の押圧閉動が可能となる状態から閉動作がなされる際に、原則的には近接対面して移動する構成とされている。従って、当該指詰防止カバー体20が、例えば、指等に押されて左右方向のいずれか一方にズレが生じた場合にも、押方向とは異なる側の戸板10の端面13に当接して、該指詰防止カバー体20の移動(ズレ)が規制される。従って、該指詰防止カバー体20と押方向側における端面13との空隙の拡大を低減でき、指詰をより効果的に防止できる。   Further, in the present embodiment, the rear surface side of the finger plug prevention cover body 20, the end surfaces 13 and 13 and the chamfered portions 14 and 14 of the door plates 10 and 10 are at least capable of pressing and closing the folding door 1. When the closing operation is performed, the principle is to move in close proximity to each other. Therefore, even when the finger clogging prevention cover body 20 is pushed by a finger or the like and is displaced in either of the left and right directions, it comes into contact with the end surface 13 of the door plate 10 on the side different from the pushing direction. The movement (displacement) of the finger plug prevention cover body 20 is restricted. Therefore, the expansion of the gap between the finger-clogging prevention cover body 20 and the end surface 13 on the pushing direction side can be reduced, and finger clogging can be prevented more effectively.

次に、本発明に係る他の実施の形態について、図面を参照しながら説明する。
図7及び図8は、第2実施形態に係る折戸について説明するための説明図である。
なお、上記第1実施形態との相違点について主に説明し、同様の構成については、同一符号を付し、その説明を省略または簡略に説明する。

この取付プレート34Aは、上記第1実施形態において説明した取付プレート34の挿し込み部38に代えて、その蝶番19側の端部に、重ね合わせ部としての被せ片部38Aを有している。
この被せ片部38Aは、図8(b)に示すように、軸受部36などが設けられた平板部から、蝶番19の取付片連結部側端部19cの厚さに応じて、段壁部37Aを形成するようにして屈曲されて形成されている。この段壁部37Aは、蝶番19の端面19dに当接させて配置され、位置決め部として機能する。
また、この被せ片部38Aには、蝶番19の取付片連結部側端部19cに開設された皿穴19eの形状に対応させた係合皿穴部39Aが絞り加工等によって形成されている。この係合皿穴部39A、及び蝶番19の取付片連結部側端部19cの皿穴19eが位置決め部として機能する。
The folding door 1A according to the present embodiment is different from the first embodiment in the configuration of the pair of mounting plates 34A and 34A of the mounting support portion 30A of the finger plugging prevention device 2A.
The mounting plate 34A has a covering piece portion 38A as an overlapping portion at the end portion on the hinge 19 side in place of the insertion portion 38 of the mounting plate 34 described in the first embodiment.
As shown in FIG. 8B, the covering piece portion 38 </ b> A is formed from a flat plate portion provided with a bearing portion 36 and the like according to the thickness of the attachment piece connecting portion side end portion 19 c of the hinge 19. It is bent to form 37A. The step wall portion 37A is disposed in contact with the end surface 19d of the hinge 19 and functions as a positioning portion.
Further, an engagement countersunk part 39A corresponding to the shape of the countersink 19e formed in the attachment piece connecting part side end 19c of the hinge 19 is formed in the covering piece part 38A by drawing or the like. The engaging countersunk hole 39A and the countersink 19e of the attachment piece connecting part side end 19c of the hinge 19 function as a positioning part.

上記構成とされた取付支持部30Aを、戸板10,10の各裏面12,12に固定する際には、図8(a)、(b)に示すように、取付支持部30Aの連結支持片31を、各戸板10,10の端面13,13間の隙間に、前後に挿通する。その状態で、一対の取付プレート34A,34Aを、各戸板10,10の裏面12,12に配置する。
次いで、各取付プレート34A,34Aの被せ片部38A,38Aを、蝶番19の取付片連結部側端部19c,19cの表面側に被せ、各被せ片部38A,38Aと、蝶番19の各取付片連結部側端部19c,19cとを重ね合わせる。
この際、被せ片部38Aの係合皿穴部39Aを、蝶番19の取付片連結部側端部19cの皿穴19eに係合させ、また、段壁部37Aを蝶番19の端面19dに当接させることで、当該取付プレート34Aが、所定の固定位置に位置決めされる。つまり、段壁部37Aと係合皿穴部39Aとによって、当該取付プレート34Aの幅方向及び上下方向の位置決めが可能となる。
When fixing the mounting support portion 30A having the above configuration to the back surfaces 12 and 12 of the door plates 10 and 10, as shown in FIGS. 8A and 8B, the connecting support piece of the mounting support portion 30A. 31 is inserted back and forth in the gap between the end faces 13 and 13 of the door plates 10 and 10. In this state, the pair of mounting plates 34A and 34A are disposed on the back surfaces 12 and 12 of the door plates 10 and 10, respectively.
Next, the covering piece portions 38A and 38A of the attachment plates 34A and 34A are placed on the surface side of the attachment piece connecting portion side ends 19c and 19c of the hinge 19, and the attachment pieces 38A and 38A and the hinge 19 are attached to each other. The one connecting portion side end portions 19c and 19c are overlapped.
At this time, the engaging countersunk portion 39A of the covering piece portion 38A is engaged with the countersink 19e of the attachment piece connecting portion side end portion 19c of the hinge 19, and the stepped wall portion 37A is contacted with the end surface 19d of the hinge 19. By making contact, the mounting plate 34A is positioned at a predetermined fixed position. In other words, the mounting plate 34A can be positioned in the width direction and the vertical direction by the step wall portion 37A and the engagement countersunk hole portion 39A.

上記のように、取付プレート34Aの位置決めがなされれば、被せ片部38Aの係合皿穴部39A、及び蝶番19の取付片連結部側端部19cの皿穴19eに固定止具Sを挿通し、戸板10の裏面12に止着させる。また、上記同様、取付プレート34Aの上端部に設けられた止具挿通孔35に、固定止具Sを挿通し、戸板10の裏面12に止着する。これにより、図7(a)、(b)に示すように、取付プレート34Aが、戸板10の裏面12に固定される。
上記構成とされた折戸1A及び指詰防止具2Aによれば、上記第1実施形態と概ね同様の効果を奏する。
As described above, when the mounting plate 34A is positioned, the fixing stopper S is inserted into the engaging countersink portion 39A of the covering piece portion 38A and the countersink hole 19e of the mounting piece connecting portion side end portion 19c of the hinge 19.

Anything that can be moved is acceptable.
Furthermore, the cushioning member provided in the finger-clogging prevention cover portion is not limited to the two members fitted in the engagement recesses of the cover body as shown in the figure, but one member that connects these in the left-right direction. It is good also as what consists of. Alternatively, the buffer portion may be formed integrally with the finger plug prevention cover portion. For example, by using two-color molding (different material molding) or the like, the front side portion is made of a relatively rigid hard synthetic resin, and is softened so as to be coupled to the left and right side portions of the front side portion. It is good also as an aspect which provides the right-and-left buffer part which consists of these synthetic resins.

さらにまた、取付支持部の連結支持片や、一対の作動片としてのリンク状部材の形状は、図例のものに限られず、取付プレートに連結されて、折戸の開閉動作に伴って、指詰防止カバー部を上記のように前後に移動させ得るものであればよい。
また、取付支持部の取付プレートの形状も図例のものに限られず、例えば、蝶番の重ね合わせ部位の表裏を挟み込むようにして、重ね合わせられるものとしてもよい。つまり、上記挿し込み部及び被せ片部の両方を備えたような形状としてもよい。
Furthermore, the shape of the link-like member as the connection support piece of the attachment support part or the pair of operation pieces is not limited to that of the illustrated example. What is necessary is just to be able to move the prevention cover part back and forth as described above.
Further, the shape of the mounting plate of the mounting support portion is not limited to the illustrated example, and for example, the mounting plate may be overlapped so as to sandwich the front and back of the overlapping portion of the hinge. That is, it is good also as a shape provided with both the said insertion part and the covering piece part.
