Description

本発明は、折戸の連結部における指詰めを防止するための指詰防止具、及びこれを備えた折戸に関する。   The present invention relates to a finger plug prevention tool for preventing finger padding at a connecting portion of a folding door, and a folding door provided with the same.

上記折戸は、例えば、クローゼット等の収納空間やキャビネット等の収納戸棚、部屋の開閉扉、或いは部屋の間仕切り用のスライドウォール（開閉壁）として使用され、複数枚の戸板を、例えば蝶番等の連結部材のヒンジピンを折り畳み支点とし、該折り畳み支点を中心として折り畳み自在に連結したものが知られている。
上記のような折戸は、閉止された状態では、複数枚の戸板が横並びに一直線に配置される。また、該折戸を開放する際には、把手等をして、ガイドレール等に沿ってスライドさせることで、開状態への移行（開動）がなされ、ガイドレールに直交する方向に向けて戸板の連結部が突出されるようにして複数枚の戸板が折り畳まれて開状態となる。
上記開状態とされた折戸を閉止する際には、把手等をして、ガイドレールに沿ってスライドさせることで閉状態への移行（閉動）がなされるが、連結された戸板間に形成される連結角（開き角）がある程度の状態（例えば、８０°〜１００°程度以上）では、折戸の上記のように突出された連結部の近傍部位を、ガイドレール側に向けて押すことによっても折戸の閉止が可能となる。 The folding door is used as, for example, a storage space such as a closet, a storage cabinet such as a cabinet, an opening / closing door of a room, or a sliding wall (opening / closing wall) for partitioning a room. 2. Description of the Related Art A member in which a hinge pin of a member is used as a folding fulcrum and connected so as to be foldable around the folding fulcrum is known.
In the folded door as described above, a plurality of door plates are arranged side by side in a straight line. Moreover, when opening the folding door, a handle or the like is slid along the guide rail or the like to make a transition (opening) to an open state, and the door plate is moved in a direction perpendicular to the guide rail. A plurality of door plates are folded so that the connecting portion protrudes to be in an open state.
When closing the folding door that is in the open state, a handle or the like is slid along the guide rail to move to the closed state (closed movement), but it is formed between the connected door plates. In a state where the connecting angle (opening angle) is a certain degree (for example, about 80 ° to 100 ° or more), by pushing the vicinity of the connecting portion protruding as described above of the folding door toward the guide rail side The folding door can be closed.

ところで、折戸は、上記のように蝶番等の連結部材によって各戸板が連結されているが、この連結部材によって、各戸板の連結部側の端面間には、僅かな隙間が形成される。この隙間は、連結部材の形状や配設態様等にもよるが、折戸が完全に開放された状態及び閉止された状態では、例えば、０．７ｍｍ〜１．３ｍｍ程度と比較的、小さい。しかしながら、開状態から閉状態へ移行する際、特に上述のように連結部の近傍部位を押すことによっても閉止が可能な程度の状態では、最大で例えば、４．０ｍｍ〜５．０ｍｍ程度の隙間が形成される。
この隙間は、大人の手指が挟まるような隙間ではないが、乳幼児等では該隙間に手指を挟みこんでしまう恐れがあった。このような隙間は、例えば、蝶番を戸板の取付面側（例えば背面側）に埋め込む等により、ある程度は、小さくでき、当該隙間における手指の挟みこみ（指詰め）を一応は、低減できる。 By the way, as for the folding door, although each doorplate is connected by connection members, such as a hinge, as mentioned above, a slight clearance gap is formed between the end surfaces by the side of the connection part of each doorplate. The gap is relatively small, for example, about 0.7 mm to 1.3 mm in a state where the folding door is completely opened and closed, although it depends on the shape and arrangement of the connecting member. However, when shifting from the open state to the closed state, especially in a state in which closing is possible even by pushing the vicinity of the connecting portion as described above, a gap of, for example, about 4.0 mm to 5.0 mm at the maximum. Is formed.
Although this gap is not a gap where an adult's fingers are pinched, there is a risk that an infant or the like may pinch fingers in the gap. Such a gap can be reduced to some extent by, for example, embedding a hinge on the mounting surface side (for example, the back side) of the door plate, and the pinching (fingering) of fingers in the gap can be reduced temporarily.

上述のような隙間における指詰めを防止するための他の構造としては、例えば、戸板の連結部側端面を面取りしたり、蝶番等で連結されていない部位の端面間に指詰めの生じない程の大きな隙間を形成したり、端面間に軟質部材を介在させたりしたものが提案されていた（例えば、下記特許文献１）。
これらの各構造では、折戸の連結部における指詰めを完全に防止するのは困難であり、また、見栄えも良くないものであった。 As another structure for preventing the finger padding in the gap as described above, for example, chamfering the end surface of the connecting portion side of the door plate, or so that finger padding does not occur between the end surfaces of the parts not connected by a hinge or the like. A large gap or a soft member interposed between the end faces has been proposed (for example, Patent Document 1 below).
In each of these structures, it is difficult to completely prevent fingering at the connecting portion of the folding door, and the appearance is not good.

また、下記特許文献２では、蝶番等の連結部材により折り畳み可能に連結された複数の扉（戸板）からなる折戸において、連結された二枚の扉のうちいずれか一方の扉の、折戸の折り畳み時に他方の扉と対向する面の連結側端部に、帯状部材を固設した折戸の連結部構造が提案されている。
上記帯状部材は、連結された二枚の扉のうちいずれか一方の扉の端部の背面側で、かつ蝶番が配置されていない部分に上下方向に沿って固設されている。また、この帯状部材は、突出部を半円形とし、その半径を、蝶番の作動半径と同径としている。
これによれば、扉を開閉するときに、扉の端辺が常に突出部の外周に接するようになり、扉の連結部における隙間が、当該帯状部材の突出部によって塞がれるようになり、折戸の開閉の際に隙間ができず、指詰めを防止できる、と説明されている。
実開昭６３−２３４８２号公報（図２参照） 特開２００４−６８３７５号公報（図３〜図５参照） Moreover, in the following patent document 2, in the folding door which consists of several doors (doorboard) connected so that folding is possible by connection members, such as a hinge, folding of the folding door of any one of the connected doors is carried out. In some cases, a folding door connecting portion structure has been proposed in which a band-like member is fixed to the connecting side end of the surface facing the other door.
The belt-like member is fixed along the vertical direction on the back side of the end of one of the two connected doors and on a portion where no hinge is arranged. Moreover, this strip | belt-shaped member makes a protrusion semicircular, and makes the radius the same diameter as the operating radius of a hinge.
According to this, when opening and closing the door, the edge of the door always comes into contact with the outer periphery of the protruding portion, and the gap in the connecting portion of the door is blocked by the protruding portion of the band-shaped member, It is described that there is no gap when the folding door is opened and closed, and finger padding can be prevented.
Japanese Utility Model Publication No. 63-23482 (see FIG. 2) JP 2004-68375 A (see FIGS. 3 to 5)

上記特許文献２に記載された折戸の連結部構造によれば、折戸の開動時及び閉動時に、上記のように連結部材によって形成される戸板の連結部側端面間の隙間においての指詰めの防止は可能ではある。
しかしながら、複数枚の戸板の連結部側端面間には、上記のように連結部材によって形成される隙間のみならず、当該折戸の開閉に伴って、連結部側端面間に拡縮される空間が形成される。上記特許文献２に記載された折戸の連結部構造では、上記のように拡縮される空間における指詰めについての考慮はなされておらず、さらなる改善が望まれていた。すなわち、上記特許文献２に記載された折戸の連結部構造においては、折戸の閉動時に、当該空間に手指が万が一、存在すれば、閉状態への移行に伴って該端面間の幅が縮まるので、該端面間に手指を挟みこんでしまう恐れがあった。 According to the folding door connecting portion structure described in Patent Document 2, when the folding door is opened and closed, finger padding in the gap between the connecting portion side end surfaces of the door plate formed by the connecting member as described above is performed. Prevention is possible.
However, not only the gap formed by the connecting member as described above, but also a space that is expanded and contracted between the connecting portion side end faces as the folding door is opened and closed is formed between the connecting portion side end surfaces of the plurality of door plates. Is done. In the folding door connecting portion structure described in Patent Document 2, consideration has not been given to finger padding in the space expanded and contracted as described above, and further improvement has been desired. That is, in the folding door connecting portion structure described in Patent Document 2, if a finger is present in the space when the folding door is closed, the width between the end faces is reduced with the transition to the closed state. Therefore, there is a risk that fingers are caught between the end faces.

また、上記特許文献２に記載された折戸の連結部構造では、折戸が完全に閉止された状態では、上記帯状部材は、背面側に位置するため、正面側から見た状態においては、折戸の美観性を阻害するようなことはない。
しかしながら、このものでは、開状態となった際、上記帯状部材が固設されていない箇所においては、蝶番が露出し、上記帯状部材が露出することと相俟って、連結部において蝶番と帯状部材とが交互に露出するような態様となり、見栄えが悪いという問題もあった。 Moreover, in the connection part structure of the folding door described in the said patent document 2, since the said strip | belt-shaped member is located in the back side in the state by which the folding door was completely closed, in the state seen from the front side, There is no such thing as disturbing aesthetics.
However, in this case, when the belt-like member is in the open state, the hinge is exposed at a location where the belt-like member is not fixed, and coupled with the exposure of the belt-like member, the hinge and the belt are formed at the connecting portion. There was also a problem that the members were exposed alternately and the appearance was poor.

本発明は、上記実情に鑑みなされたものであり、折戸の美観性を損なうことなく、折戸の連結部に形成される隙間や空間等における指の挟みこみを防止し得る指詰防止具、及びこれを備えた折戸を提供することを目的としている。   The present invention has been made in view of the above circumstances, and a finger-clogging prevention device that can prevent a finger from being caught in a gap or a space formed in a connecting portion of the folding door without impairing the aesthetics of the folding door, and It aims at providing the folding door provided with this.

And a bar-like member interposed along the vertical direction in the connecting portion of the folding door, and a support means for movably supporting the bar-like member, the support means supporting the bar-like member on the folding fulcrum side. An urging member urging toward the urging member, and a pair of support bases that are connected to the urging member and are respectively attached to both end surfaces on the connecting portion side of the plurality of door plates. With the opening and closing of the folding door, when the folding door is closed, the space between the end faces on the connection part side of the plurality of door plates is moved in a direction away from the folding fulcrum, while when the folding door is opened, the folding fulcrum is moved to the folding fulcrum. Front in the direction of approach Characterized in that it is structured to move the space between coupling part-side end face.

本発明に係る前記指詰防止具においては、前記棒状部材を、前記折り畳み支点側の側面部が凸曲面形状とされたものとし、該側面部が前記連結部側端面に当接して前記連結部側端面間の空間を移動する構造としてもよい。   In the finger clogging prevention device according to the present invention, the side surface portion on the folding fulcrum side of the rod-shaped member is formed in a convex curved surface shape, and the side surface portion abuts on the end surface on the connection portion side and the connection portion. It is good also as a structure which moves the space between side end surfaces.

また、前記目的を達成するために、本発明に係る折戸は、複数枚の戸板を、折り畳み支点を中心として折り畳み自在に連結した折戸であって、当該折戸の連結部に上下方向に沿って介在された棒状部材と、該棒状部材を移動可能に支持する支持手段とを備え、前記支持手段は、前記棒状部材を前記折り畳み支点側に向けて付勢する付勢部材と、該付勢部材に連結され、前記複数枚の戸板の連結部側の両端面にそれぞれ取付けられた一対の支持基部とを備えており、前記棒状部材は、当該折戸の開閉に伴って、閉動時には、前記折り畳み支点から遠ざかる方向に前記複数枚の戸板の連結部側端面間の空間を移動する一方、開動時には、前記折り畳み支点に近づく方向に前記連結部側端面間の空間を移動する構造とされていることを特徴とする。   In order to achieve the above object, the folding door according to the present invention is a folding door in which a plurality of door plates are connected so as to be foldable around a folding fulcrum, and is interposed along the vertical direction at a connecting portion of the folding door. And a supporting means for movably supporting the rod-shaped member, the supporting means biasing the rod-shaped member toward the folding fulcrum side, and the biasing member And a pair of support bases respectively attached to both end faces of the plurality of door plates on the connecting part side, and the folding member is opened when the folding door is opened and closed. The space between the connecting portion side end faces of the plurality of door plates is moved in a direction away from the door, and at the time of opening, the space between the connecting portion side end faces is moved in a direction approaching the folding fulcrum. Features.

本発明に係る前記折戸においては、前記棒状部材を、前記折り畳み支点側の側面部が凸曲面形状とされたものとし、該側面部が前記連結部側端面に当接して前記連結部側端面間の空間を移動する構造としてもよい。   In the folding door according to the present invention, the side surface portion on the folding fulcrum side of the folding member is a convex curved surface, and the side surface portion is in contact with the end surface on the connection portion side, and between the end surfaces on the connection portion side. It is good also as a structure which moves this space.

本発明に係る前記折戸においては、前記複数枚の戸板の各連結部側端面に、面取り部がそれぞれ形成されたものとし、前記棒状部材を、当該折戸が閉止された状態で、前記戸板の面取り部間に、少なくともその一部が収容される構造としてもよい。
本発明に係る前記折戸においては、前記棒状部材を、当該折戸の上下方向長さと略同長さとされたものとしてもよい。 In the folding door according to the present invention, a chamfered portion is formed on each of the connecting portion side end surfaces of the plurality of door plates, and the bar-like member is chamfered with the folding door closed. It is good also as a structure in which at least one part is accommodated between parts.
In the folding door according to the present invention, the rod-shaped member may be substantially the same length as the vertical length of the folding door.

本発明に係る指詰防止具を折戸に用いることによって、以下のような効果を奏する。
すなわち、前記棒状部材は、折戸の連結部に上下方向に沿って介在されるので、該棒状部材によって、戸板間の隙間が隠蔽される。従って、折戸の美観性を向上させることができるとともに、当該隙間における指詰めを防止できる。このような棒状部材の長さは、乳幼児等の身長に合わせて、少なくとも乳幼児等の手が届く範囲の高さ以上の長さを有するものとしてもよいが、折戸の上下方向の略全長に亘って介在される長さとされたものとすれば、当該棒状部材によって、戸板間の隙間がその上下方向の全長に亘って隠蔽され、より美観性を向上させることができる。 The following effects can be obtained by using the fingernail preventer according to the present invention for a folding door.
That is, since the bar-shaped member is interposed along the vertical direction in the connecting portion of the folding door, the gap between the door plates is concealed by the bar-shaped member. Therefore, it is possible to improve the aesthetics of the folding door and to prevent finger filling in the gap. The length of such a bar-shaped member may be at least as high as the reach of an infant or the like in accordance with the height of the infant or the like, but over the substantially entire length of the folding door in the vertical direction. If the length is interposed, the bar-like member conceals the gap between the door plates over the entire length in the vertical direction, and the aesthetics can be further improved.

また、上記指詰防止具の棒状部材は、折戸の開閉に伴って、該折戸の閉動時には、前記折り畳み支点から遠ざかる方向に前記複数枚の戸板の連結部側端面間の空間を移動する一方、前記折戸の開動時には、前記折り畳み支点に近づく方向に前記連結部側端面間の空間を移動する構造とされている。従って、折戸が開状態から閉状態へ移行する際に、戸板の連結部側端面間に形成される空間を、当該棒状部材が上記のように移動するので、当該空間に手指が存在している状態においても、該棒状部材の折り畳み支点から遠ざかる方向への移動によって、手指が該空間からはじき出されるようにして、指詰めの防止がなされる。   In addition, the bar-shaped member of the anti-clogging tool moves along the space between the end faces of the plurality of door plates in the direction away from the folding fulcrum when the folding door is closed as the folding door is opened and closed. When the folding door is opened, the space between the end faces on the connection part side is moved in a direction approaching the folding fulcrum. Therefore, when the folding door shifts from the open state to the closed state, the bar-shaped member moves as described above in the space formed between the connecting portion side end faces of the door plate, and thus fingers exist in the space. Even in the state, by moving the rod-shaped member in the direction away from the folding fulcrum, fingers are prevented from being pushed out of the space, thereby preventing the fingers from being stuffed.

本発明に係る前記指詰防止具において、前記棒状部材を、折り畳み支点側の側面部が凸曲面形状とされたものとし、該側面部が前記連結部側端面に当接して前記連結部側端面間の空間を移動する構造とすれば、以下のような効果を奏する。
すなわち、当該指詰防止具が折戸に用いられた状態では、その棒状部材の凸曲面形状とされた側面部が連結部側端面に当接して移動するので、戸板の各連結部側端面と、棒状部材との間に隙間が形成されず、指詰めを確実に防止できる。 In the finger clogging prevention device according to the present invention, the side surface portion on the folding fulcrum side of the bar-shaped member is formed in a convex curved surface shape, and the side surface portion abuts on the end surface on the connection portion side, so If it is made the structure which moves the space between, there exist the following effects.
That is, in the state where the finger clogging prevention tool is used for a folding door, the side surface portion of the rod-shaped member that is a convex curved surface moves in contact with the connecting portion side end surface, so that each connecting portion side end surface of the door plate, A gap is not formed between the rod-shaped member and finger filling can be reliably prevented.

本発明に係る前記指詰防止具において、前記支持手段として、前記棒状部材を前記折り畳み支点側に向けて付勢する付勢部材と、該付勢部材に連結され、前記折戸に取付けられる支持基部とを備えたものとすれば、折り畳み支点側に向けて付勢されているので、当該棒状部材が移動する際に、戸板の各連結部側端面に当接して移動する。従って、指詰めを確実に防止できる。
上記構成においては、棒状部材の折り畳み支点から遠ざかる方向への移動は、他の手段によりなされるようにしてもよい。或いは、上述のように折り畳み支点側の側面部が凸曲面形状とされている棒状部材を採用したものとすれば、該棒状部材は、折戸の閉動に伴って徐々に狭小となる戸板の連結部側端面間の上記空間において、これら各端面に側面部の凸曲面が沿うようにして、付勢部材による折り畳み支点側への付勢力に抗して、折り畳み支点から遠ざかる方向への移動が、スムーズになされる。 In the finger clogging prevention device according to the present invention, as the support means, a biasing member that biases the bar-shaped member toward the folding fulcrum side, and a support base that is connected to the biasing member and attached to the folding door When the rod-shaped member moves, it moves in contact with the end face of each connecting portion of the door plate. Therefore, it is possible to reliably prevent finger jamming.
In the said structure, you may make it make the movement to the direction away from the folding fulcrum of a rod-shaped member by another means. Alternatively, if a rod-shaped member having a convex curved surface at the folding fulcrum side as described above is adopted, the rod-shaped member is connected to the door plate that gradually narrows as the folding door is closed. In the above-mentioned space between the part side end surfaces, the movement in the direction away from the folding fulcrum is performed against the urging force toward the folding fulcrum side by the urging member so that the convex curved surface of the side surface part follows each of the end surfaces. Made smooth.

また、上記支持基部を備えた指詰防止具において、前記支持基部を、前記複数枚の戸板の連結部側の両端面にそれぞれ取付けられる一対の支持基部とすれば、取付け対象である折戸を、例えば、半開き或いは開放させて、連結部側の両端面を手前側に露出させることで、上記支持基部を手前側から容易に折戸に取付けることができる。また、折戸が閉止された状態においては、該支持基部は、隣接する戸板の各端面間に収容された状態となるので、例えば、上記支持基部を、戸板の背面側に取付けるものと比べて、折戸の背面側の美観性を向上させることができる。   Moreover, in the fingernail preventer provided with the support base, if the support base is a pair of support bases that are respectively attached to both end surfaces on the connecting part side of the plurality of door plates, the folding door to be attached is For example, the support base can be easily attached to the folding door from the near side by opening it halfway or opening it and exposing the both end faces on the connecting portion side to the near side. Further, in the state where the folding door is closed, the support base is in a state of being accommodated between each end face of the adjacent door plate, for example, compared with the support base attached to the back side of the door plate, The aesthetics on the back side of the folding door can be improved.

また、本発明に係る前記折戸は、当該折戸の連結部に上下方向に沿って介在された棒状部材と、該棒状部材を移動可能に支持する支持手段とを備えている。また、前記棒状部材は、当該折戸の開閉に伴って、閉動時には、前記折り畳み支点から遠ざかる方向に前記複数枚の戸板の連結部側端面間の空間を移動する一方、開動時には、前記折り畳み支点に近づく方向に前記連結部側端面間の空間を移動する構造とされている。
従って、本発明に係る折戸によれば、上記指詰防止具が奏する効果と同様、当該折戸の美観性を向上させることができるとともに、当該折戸の連結部における指詰めを防止することができる。 In addition, the folding door according to the present invention includes a bar-like member interposed along a vertical direction at a connecting portion of the folding door, and a support unit that supports the bar-like member so as to be movable. In addition, when the folding door is opened and closed, the bar-shaped member moves in the space between the end faces of the plurality of door plates in the direction away from the folding fulcrum when the folding door is opened, while the folding fulcrum is opened when the folding door is opened. It is set as the structure which moves the space between the said connection part side end surfaces in the direction which approaches.
Therefore, according to the folding door which concerns on this invention, while being able to improve the aesthetics of the said folding door similarly to the effect which the said finger padding prevention tool show | plays, the finger padding in the connection part of the said folding door can be prevented.

本発明に係る前記折戸において、前記棒状部材を、前記折り畳み支点側の側面部が凸曲面形状とされたものとし、該側面部が前記連結部側端面に当接して前記連結部側端面間の空間を移動する構造とすれば、上記同様、当該折戸の連結部における指詰めを確実に防止できる。

The space side that protrudes toward the front side is referred to as the front side, and the opposite is assumed to be the back side. That is, when each folding door is constructed as an open / close door for a storage space such as a closet as in each reference example and each embodiment described later, the folding door faces the folding door on the indoor space (residential space) side. The space where the user who opens and closes the door is the front side, and the storage space side is the back side.

本参考例に係る折戸１０は、図１に示すように、大略的に、２枚の戸板１１，１３と、該戸板１１，１３を、折り畳み自在に連結する連結部材１５と、該連結部材１５によって連結された戸板１１，１３の連結部ｃｐに設けられた指詰防止具２０とを備えている。
上記折戸１０は、本参考例では、図１に示すように、建物の室内空間（居住空間）ＬＳと、収納空間ＳＳとの間を仕切る内壁１に開設された開口部ｏｐを、２組の折戸１０，１０によって閉塞或いは開放するクローゼット用の開閉扉を構成している。 As shown in FIG. 1, the folding door 10 according to this reference example is roughly composed of two door plates 11 and 13, a connecting member 15 that connects the door plates 11 and 13 in a foldable manner, and the connecting member 15. And the finger plug prevention tool 20 provided in the connection part cp of the door plates 11 and 13 connected by.
In the present reference example , the folding door 10 has two sets of openings op formed in the inner wall 1 that partitions the interior space (residential space) LS of the building and the storage space SS, as shown in FIG. An open / close door for a closet that is closed or opened by the folding doors 10 and 10 is configured.

上記各折戸１０は、開口部ｏｐに設けられた四方枠（上枠（不図示）、下枠２、縦枠３，３）内に配置され、上枠の上レール（不図示）及び下枠２の下レール２ａに開閉自在に支持されている。
上記２枚の戸板１１，１３のうち、一方はスライド不能とされた固定戸板１１とされ、他方はスライド可能とされた可動戸板１３とされている。すなわち、戸板１１の枢軸１１ａは、縦枠３の近傍において、回動自在、スライド不能に、上枠及び下枠２に支持されており、戸板１３の枢軸１３ａは、上レール及び下レール２ａに沿ってスライド可能、回動自在に、上枠及び下枠２に支持されている。これら戸板をスライド可能とする構成は、公知のランナー（転動体、走行体等）やピボット等を採用するようにしてもよい。
尚、図において、符号１６は、戸板１３に設けられた操作具としての把手（取っ手）である。また、上記固定戸板１１もスライド可能な構成としてもよい。 Each of the folding doors 10 is arranged in a four-sided frame (upper frame (not shown), lower frame 2, vertical frames 3 and 3) provided in the opening op, and an upper rail (not shown) and lower frame of the upper frame. 2 is supported by the lower rail 2a so as to be freely opened and closed.
One of the two door plates 11 and 13 is a fixed door plate 11 that is not slidable, and the other is a movable door plate 13 that is slidable. That is, the pivot 11a of the door plate 11 is supported by the upper and lower frames 2 in the vicinity of the vertical frame 3 so as to be rotatable and non-slidable. The pivot 13a of the door plate 13 is supported by the upper rail and the lower rail 2a. The upper frame and the lower frame 2 are supported so as to be slidable and rotatable. A configuration that enables sliding of these door plates may employ a known runner (such as a rolling element or a traveling body) or a pivot.
In the figure, reference numeral 16 denotes a handle (handle) as an operation tool provided on the door plate 13. The fixed door plate 11 may also be configured to be slidable.

また、上記戸板１１，１３の連結部ｃｐ側の端面１２，１４は、その手前側部がＣ面取り加工等によって形成された面取り部１２ａ，１４ａとされている。これら面取り部１２ａ，１４ａの形状は、折戸１０が閉止され、各面取り部１２ａ，１４ａが互いに対向された状態で、平面視して手前側（室内空間ＬＳ側）に向けて拡開する形状とされている。
上記連結部材１５は、本参考例では、ヒンジピン１５ａと、該ヒンジピン１５ａを支点として折り畳み自在とされた一対の取付ハネ１５ｂ，１５ｂを有した蝶番１５とされている。すなわち、本参考例では、上記ヒンジピン１５ａが、戸板１１，１３の折り畳み支点を構成する。
該蝶番１５は、図４（ｂ）に示すように、各戸板１１，１３の連結部ｃｐ近傍の背面に、それぞれの取付ハネ１５ｂ，１５ｂを木ねじ等によって止着させることで、固着されている。これら蝶番１５は、連結部ｃｐの上下方向に沿って適所に複数個（図例では３個）設けられている。 Further, the end faces 12 and 14 on the connecting part cp side of the door plates 11 and 13 are chamfered parts 12a and 14a whose front side parts are formed by C chamfering or the like. The shape of these chamfered portions 12a and 14a is such that the folding door 10 is closed and the chamfered portions 12a and 14a are opposed to each other, and expands toward the front side (the interior space LS side) in plan view. Has been.
In this reference example , the connecting member 15 is a hinge 15 having a hinge pin 15a and a pair of attachment hoods 15b and 15b that can be folded around the hinge pin 15a as a fulcrum. That is, in the present reference example , the hinge pin 15a constitutes the folding fulcrum of the door plates 11 and 13.
As shown in FIG. 4 (b), the hinge 15 is fixed to the back surface of the door plates 11 and 13 in the vicinity of the connecting portion cp by fixing the attachment honey 15b and 15b with wood screws or the like. . A plurality (three in the illustrated example) of hinges 15 are provided at appropriate positions along the vertical direction of the connecting portion cp.

上記構成とされた折戸１０は、図１において左方に位置する折戸１０のように、二枚の戸板１１，１３を横並びに一直線とした状態が、閉状態とされ、図１において右方に位置する折戸１０のように、二枚の戸板１１，１３を手前側（上レール及び下レール２ａに直交する方向）に向けて連結部ｃｐを突出させるようにして折り畳んだ状態が、開状態とされる。
また、図１において右方に位置する折戸１０を二点鎖線で示した状態は、上記閉状態から開状態への移行（開動）の途中、或いは上記開状態から閉状態への移行（閉動）の途中の状態と、閉状態とを示している。
上記折戸１０の開動及び閉動は、把手１６をしてなされるが、上記閉動の際において、連結された各戸板１１，１３の背面のなす角θ（開き角θ）が、例えば、８０°〜１００°程度以上の状態では、折戸１０の連結部ｃｐ近傍部位を、手前側（室内空間ＬＳ側）から背面側（収納空間ＳＳ側）に向けて押すことによっても折戸１０の閉動（以下、押圧閉動と略す）が可能とされている。 In the folding door 10 having the above-described configuration, the state in which the two door plates 11 and 13 are arranged side by side as in the folding door 10 located on the left side in FIG. Like the folding door 10 that is positioned, the state in which the two door plates 11 and 13 are folded toward the front side (direction perpendicular to the upper rail and the lower rail 2a) so that the connecting portion cp protrudes is an open state. Is done.
Further, the state in which the folding door 10 located on the right side in FIG. 1 is indicated by a two-dot chain line is in the middle of the transition from the closed state to the open state (opening) or from the open state to the closed state (closed motion). ) And a closed state are shown.
The folding door 10 is opened and closed by the handle 16, and the angle θ (opening angle θ) formed by the back surfaces of the connected door plates 11 and 13 at the closing time is, for example, 80 In a state where the angle is about 100 ° or more, the folding door 10 can be closed and closed by pushing the vicinity of the connecting portion cp of the folding door 10 from the front side (the indoor space LS side) toward the back side (the storage space SS side) ( Hereinafter, it is referred to as “pressing closing movement”.

上記のように、折戸１０の開動及び閉動がなされる際、上記戸板１１，１３の各連結部側端面１２，１４間には、後記するように折戸１０の開閉に伴って、拡大及び縮小される扇状の空間ｆｓ（図２及び図３も参照）が形成される。
この折戸１０の開閉に伴って拡縮される扇状の空間ｆｓに、上記折戸１０の開動時及び閉動時に背面側及び手前側に向けて移動する指詰防止具２０の棒状部材２１が介在される。 As described above, when the folding door 10 is opened and closed, between the connecting portion side end surfaces 12 and 14 of the door plates 11 and 13, as will be described later, as the folding door 10 is opened and closed, enlargement and reduction are performed. A fan-shaped space fs (see also FIGS. 2 and 3) is formed.
In the fan-shaped space fs that is expanded and contracted as the folding door 10 is opened and closed, the bar-shaped member 21 of the finger plug prevention tool 20 that moves toward the back side and the near side when the folding door 10 is opened and closed is interposed. .

上記指詰防止具２０は、図１の一点鎖線内の拡大図に示すように、大略的に、上記折戸１０の連結部ｃｐに上下方向に沿って介在され、かつ、蝶番１５の手前側に介在された棒状部材２１と、該棒状部材２１を移動可能に支持する支持手段２４とを備えている。
上記棒状部材２１は、本参考例では、図例のように、長尺中空円筒状とされており、当該棒状部材２１の手前側部２２及び背面側部２３のいずれも、凸曲面形状とされている。
すなわち、本参考例では、棒状部材２１は、ヒンジピン１５ａ側の側面部となる背面側部２３が凸曲面形状とされている。 As shown in the enlarged view in the alternate long and short dash line in FIG. 1, the finger clogging prevention device 20 is generally interposed in the connecting portion cp of the folding door 10 along the vertical direction, and on the front side of the hinge 15. An interposed rod-shaped member 21 and support means 24 that movably supports the rod-shaped member 21 are provided.
In the present reference example , the rod-like member 21 has a long hollow cylindrical shape as shown in the figure, and both the front side portion 22 and the back side portion 23 of the rod-like member 21 have a convex curved shape. ing.
That is, in this reference example , the bar-like member 21 has a convex curved surface at the back side portion 23 which is a side portion on the hinge pin 15a side.

上記凸曲面形状とされた背面側部２３の形状は、図例のような横断面が半円形状とされたものに限られない。例えば、上記押圧閉動が可能となる開き角θとされた状態から完全に閉止されるまで、該背面側部２３が、各戸板１１，１３の上記端面１２，１４（面取り部１２ａ，１４ａも含む）に常に当接するような形状としてもよい。
また、該棒状部材２１は、図４（ａ）に示すように、折戸１０の上下方向長さと略同長さとされている。 The shape of the back side portion 23 having the convex curved surface shape is not limited to that having a semicircular cross section as shown in the figure. For example, until the back side 23 is completely closed from the state of the opening angle θ that enables the pressing and closing, the end surfaces 12 and 14 of the door plates 11 and 13 (the chamfers 12a and 14a are also chamfered). It is good also as a shape which always contacts | abuts.
Further, as shown in FIG. 4A, the rod-shaped member 21 has substantially the same length as the vertical length of the folding door 10.

また、上記棒状部材２１の横幅は、図２（ａ）に示すような最大幅となった状態における上記端面１２，１４間（各端面１２，１４の背面側縁部間）に形成される隙間ｇの幅よりも、少なくとも大とされている。また、本参考例では、該棒状部材２１の横幅は、上記折戸１０が閉止された状態で上記面取り部１２ａ，１４ａ間（各面取り部１２ａ，１４ａの手前側縁部間）の幅と略同幅或いは、やや大とされた幅とされている。
上記のような棒状部材２１の形状や大きさは、後記するように、棒状ゴム体（付勢部材）２５による背面側への付勢と、折戸１０の閉動に伴う戸板１１，１３の連結部側端面１２，１４の近接作用とによってなされる当該棒状部材２１の移動が可能となるよう、戸板１１，１３の厚さや面取り部の形状等に合わせて、適宜、設計すればよい。 Further, the horizontal width of the rod-shaped member 21 is a gap formed between the end faces 12 and 14 (between the rear side edges of the end faces 12 and 14) in a state where the maximum width is as shown in FIG. It is at least larger than the width of g. Moreover, in this reference example , the horizontal width of the rod-shaped member 21 is substantially the same as the width between the chamfered portions 12a and 14a (between the front side edges of the chamfered portions 12a and 14a) in a state where the folding door 10 is closed. It is set to a width or a slightly larger width.
As described later, the shape and size of the bar-shaped member 21 described above are biased toward the back side by a bar-shaped rubber body (biasing member) 25 and the connection of the door plates 11 and 13 accompanying the closing movement of the folding door 10. What is necessary is just to design suitably according to the thickness of the doorplates 11 and 13, the shape of a chamfering part, etc. so that the movement of the said rod-shaped member 21 made by the proximity | contact action of the part side end surfaces 12 and 14 may be attained.

棒状部材２１を上記のような形状とし、戸板１１，１３に面取り部１２ａ，１４ａを形成することにより、図３（ｂ）に示すように、折戸１０が閉止された状態では、該棒状部材２１は、その略半分が上記面取り部１２ａ，１４ａ間の空間に収容される構造となる。これにより、棒状部材２１の手前側への突出量が、例えば、戸板の各連結部側端面に面取り形状が形成されていない折戸とされたものに比べて、小さくなり、折戸１０の美観性が向上される。   By forming the bar-shaped member 21 as described above and forming the chamfered portions 12a and 14a on the door plates 11 and 13, as shown in FIG. Has a structure in which approximately half is accommodated in the space between the chamfered portions 12a and 14a. Thereby, the protrusion amount to the near side of the rod-shaped member 21 becomes smaller than, for example, a folding door in which a chamfered shape is not formed on each connecting portion side end surface of the door plate, and the aesthetics of the folding door 10 are improved. Be improved.

上記棒状部材２１は、例えば、金属材や硬質の合成樹脂材からなるものとしてもよい。
上記金属材としては、スチールや炭素鋼、ステンレス鋼、アルミニウム、アルミニウム合金等、どのようなものでもよいが、鋼鉄材等と比べて、比較的軽量かつ安価であるアルミニウムからなるものとしてもよい。このようにアルミ材からなるものとすることにより、シルバー調の色調となり、戸板１１，１３間に配された状態で美観性に優れたものとなる。 The rod-shaped member 21 may be made of, for example, a metal material or a hard synthetic resin material.
The metal material may be any material such as steel, carbon steel, stainless steel, aluminum, aluminum alloy, etc., but may be made of aluminum that is relatively light and inexpensive compared to steel materials. By being made of an aluminum material in this way, the color tone becomes silver, and the aesthetic appearance is excellent in a state of being arranged between the door plates 11 and 13.

上記支持手段２４は、少なくとも押圧閉動が可能となる状態から、当該折戸１０の閉動がなされて閉止されるまで、上記棒状部材２１を常時、背面側（ヒンジピン１５ａ側）に向けて付勢する棒状ゴム体（付勢部材）２５と、該棒状ゴム体２５に連結され、折戸１０に取付けられた固定ゴム板（支持基部）２７とを備えている。
上記支持手段２４は、図４（ｂ）に示すように、連結部ｃｐの上下方向に沿って適所に複数個（図例では３個）設けられている。
上記棒状ゴム体２５は、上記棒状部材２１の背面側部２３に開設された挿通孔等に挿通されて、その基端部が棒状部材２１に固定され、背面側に向けて棒状に延出しており、他端部が固定ゴム板２７の挿通孔に挿通されて、止具２６によって固定されている。 The support means 24 always urges the bar-shaped member 21 toward the back side (hinge pin 15a side) from a state where at least pressing and closing is possible until the folding door 10 is closed and closed. And a fixed rubber plate (support base) 27 connected to the rod-shaped rubber body 25 and attached to the folding door 10.
As shown in FIG. 4B, a plurality (three in the illustrated example) of the support means 24 are provided at appropriate positions along the vertical direction of the connecting portion cp.
The rod-like rubber body 25 is inserted into an insertion hole or the like provided in the back side portion 23 of the rod-like member 21, and its base end portion is fixed to the rod-like member 21 and extends in a rod shape toward the back side. The other end is inserted into the insertion hole of the fixed rubber plate 27 and fixed by the stopper 26.

上記棒状ゴム体２５は、上記折戸１０の押圧閉動が可能となる状態（図２（ａ）参照）において、少なくとも自然長の状態で、上記棒状部材２１の背面側部２３を、各戸板１１，１３の各端面１２，１４に当接させ得る長さとされている。また、該棒状ゴム体２５は、折戸１０が完全に閉止された状態（図３（ｂ）参照）で、後記するように手前側に移動された状態の上記棒状部材２１を支持可能なように、その弾性変形を伴う伸長が可能とされている。
上記固定ゴム板２７は、隙間ｇを跨ぐように架け渡されて、各戸板１１，１３の連結部ｃｐ近傍の背面に、木ねじ等の止着具２８，２８によって止着されている（図２及び図３も参照）。尚、上記棒状ゴム体２５に連結される支持基部としては、上記のような固定ゴム板２７に限られず、該棒状ゴム体２５を支持可能で、折戸１０に取付け可能なものであればどのようなものでもよい。また、棒状ゴム体２５の形状も棒状に限られず、上記隙間ｇに挿通可能な薄板状のものとしてもよい。 In the state where the folding door 10 can be pressed and closed (see FIG. 2A), the rod-like rubber body 25 is at least in the natural length state so that the back side portion 23 of the rod-like member 21 is connected to each door plate 11. , 13 has a length that can be brought into contact with each of the end faces 12, 14. Further, the bar-like rubber body 25 can support the bar-like member 21 in a state where it is moved to the front side as will be described later in a state in which the folding door 10 is completely closed (see FIG. 3B). In addition, it is possible to extend with the elastic deformation.
The fixed rubber plate 27 is bridged across the gap g, and is fixed to the back surface of the door plates 11 and 13 in the vicinity of the connecting portion cp by fixing tools 28 and 28 such as wood screws (FIG. 2). And also FIG. 3). The support base connected to the rod-shaped rubber body 25 is not limited to the fixed rubber plate 27 as described above, and any support base that can support the rod-shaped rubber body 25 and can be attached to the folding door 10 is used. It may be anything. Further, the shape of the rod-shaped rubber body 25 is not limited to a rod shape, and may be a thin plate shape that can be inserted into the gap g.

上記構成とされた指詰防止具２０によれば、既設の折戸１０に対しても後付け可能となる。例えば、棒状ゴム体２５が取付けられた棒状部材２１を、折戸１０の蝶番１５の手前側に介在させ、その棒状ゴム体２５を上記隙間ｇに挿通し、該棒状ゴム体２５の上記他端部を、固定ゴム板２７の上記挿通孔に挿通させて止具２６によって固定する。次いで、固定ゴム板２７を、各戸板１１，１３の背面に止着具２８，２８によって固定することで、既設の折戸１０に取付けるようにしてもよい。   According to the finger clogging prevention device 20 having the above configuration, it can be retrofitted to the existing folding door 10. For example, the rod-like member 21 to which the rod-like rubber body 25 is attached is interposed on the front side of the hinge 15 of the folding door 10, the rod-like rubber body 25 is inserted into the gap g, and the other end portion of the rod-like rubber body 25 is inserted. Is inserted into the insertion hole of the fixed rubber plate 27 and fixed by the stopper 26. Next, the fixed rubber plate 27 may be attached to the existing folding door 10 by fixing the fixed rubber plate 27 to the back surfaces of the door plates 11 and 13 with the fastening devices 28 and 28.

次に、図２及び図３に基づいて、折戸１０の閉動時及び開動時における当該折戸１０の指詰防止構造について説明する。
まず、図２（ａ）に示すように、押圧閉動が可能となる状態において、棒状部材２１は、その背面側部２３を、各戸板１１，１３の各端面１２，１４の背面側近傍に当接させて、自然長或いは弾性変形を伴い伸長された上記棒状ゴム体２５によって支持されている。
上記状態から、折戸１０の連結部ｃｐ近傍部位の戸板１１，１３の手前側面を、背面側に向けて押す、或いは、把手１６をして折戸１０をスライドさせることにより、図２（ｂ）に示すように、各戸板１１，１３の上記端面１２，１４間に形成された扇状の空間ｆｓが、当該閉動に伴って徐々に小さくなる。このように、空間ｆｓが小さくなるに従い、各戸板１１，１３の各端面１２，１４間が徐々に近接する。この近接に伴い、上記棒状部材２１は、上記棒状ゴム体２５の背面側への付勢力に抗して、凸曲面形状とされた背面側部２３が各端面１２，１４を滑るようにして、各端面１２，１４間の空間ｆｓを手前側に向けて移動する。すなわち、棒状部材２１がヒンジピン１５ａから遠ざかる方向に移動する。 Next, based on FIG.2 and FIG.3, the finger-clogging prevention structure of the said folding door 10 at the time of closing and opening of the folding door 10 is demonstrated.
First, as shown in FIG. 2 (a), in a state where pressing and closing are possible, the bar-like member 21 has its back side portion 23 in the vicinity of the back side of each end face 12, 14 of each door plate 11, 13. The rod-shaped rubber body 25 is brought into contact with and extended with a natural length or elastic deformation.
From the above state, the front side surfaces of the door plates 11 and 13 in the vicinity of the connecting portion cp of the folding door 10 are pushed toward the back side, or the folding door 10 is slid by holding the handle 16 to FIG. As shown, the fan-shaped space fs formed between the end faces 12 and 14 of the door plates 11 and 13 gradually decreases with the closing movement. Thus, as the space fs becomes smaller, the end surfaces 12 and 14 of the door plates 11 and 13 gradually approach each other. Along with this proximity, the rod-like member 21 resists the biasing force toward the back side of the rod-like rubber body 25 so that the back side portion 23 having a convex curved surface slides on the end surfaces 12 and 14, The space fs between the end faces 12 and 14 moves toward the front side. That is, the rod-shaped member 21 moves in a direction away from the hinge pin 15a.

上記状態からさらなる閉動がなされると、図３（ａ）に示すように、棒状部材２１は、各戸板１１，１３の各端面１２，１４の面取り部１２ａ，１４ａ間を、上記同様、手前側に向けて移動する。
また、上記状態からさらなる閉動がなされると、図３（ｂ）に示すように、折戸１０は、完全に閉止された状態となる。この状態では、棒状部材２１は、その背面側部２３の略全体が、各戸板１１，１３の面取り部１２ａ，１４ａ間に形成された空間に収容された状態で、棒状ゴム体２５によって支持されている。
つまり、上記のように、指詰防止具２０は、その棒状部材２１が折戸１０の閉動に伴って、ヒンジピン１５ａから遠ざかるようにして、手前側にせり出される構造とされている。 When further closing is performed from the above state, as shown in FIG. 3A, the bar-like member 21 is moved forward between the chamfered portions 12a and 14a of the end surfaces 12 and 14 of the door plates 11 and 13, as described above. Move towards the side.
Further, when the door is further closed from the above state, as shown in FIG. 3B, the folding door 10 is completely closed. In this state, the rod-shaped member 21 is supported by the rod-shaped rubber body 25 in a state where substantially the entire back side portion 23 is accommodated in a space formed between the chamfered portions 12 a and 14 a of the door plates 11 and 13. ing.
That is, as described above, the finger clogging prevention device 20 has a structure in which the rod-like member 21 protrudes to the near side as the folding door 10 is moved away from the hinge pin 15a.

一方、折戸１０が完全に閉止された図３（ｂ）に示す状態から、当該折戸１０を開動させる際には、把手１６（図１参照）を、手前側かつ固定側の戸板１１側に向けて引くことで、開動がなされる。
この折戸１０の開動がなされる際には、その開動に伴い、上記棒状部材２１は、上記棒状ゴム体２５によって、閉止された状態から少なくとも押圧閉動が可能となる状態までは、常時、背面側に向けて付勢されているので、各戸板１１，１３の各端面１２，１４の面取り部１２ａ，１４ａ間（図３（ａ）参照）、及び各戸板１１，１３の各端面１２，１４間（図２（ｂ）、（ａ）参照）を、順次、背面側に向けて移動する。すなわち、ヒンジピン１５ａに近づく方向に移動する。
図２（ａ）に示す状態から、上記折戸１０が完全に開放された状態では、図１の一点鎖線内の拡大図に示すように、棒状部材２１の背面側部２３は、蝶番１５のヒンジピン１５ａに当接し、背面側への移動が規制されている。尚、このように完全に開放された状態で、ヒンジピン１５ａに規制されるものとせず、各戸板１１，１３の各端面１２，１４の背面側近傍に当接して規制されるものとしてもよい。 On the other hand, when opening the folding door 10 from the state shown in FIG. 3B in which the folding door 10 is completely closed, the handle 16 (see FIG. 1) is directed toward the door plate 11 side on the front side and the fixed side. Opening is done by pulling.
When the folding door 10 is opened, the bar-shaped member 21 is always moved from the closed state to the state in which the bar-shaped rubber body 25 can be at least pressed and closed by the bar-shaped rubber body 25. Since it is urged | biased toward the side, between each chamfering part 12a and 14a of each end surface 12 and 14 of each doorplate 11 and 13 (refer Fig.3 (a)), and each end surface 12 and 14 of each doorplate 11 and 13 The space (see FIGS. 2B and 2A) is sequentially moved toward the back side. That is, it moves in a direction approaching the hinge pin 15a.
In the state where the folding door 10 is completely opened from the state shown in FIG. 2A, the rear side portion 23 of the rod-shaped member 21 is a hinge pin of the hinge 15 as shown in the enlarged view in the dashed line in FIG. The contact to 15a is restricted and the movement to the back side is regulated. In addition, it is good not to restrict | limit to the hinge pin 15a in the state open | released completely in this way, but to contact | abut to the back side vicinity of each end surface 12 and 14 of each doorplate 11 and 13.

以上のように、本参考例に係る指詰防止具２０を備えた折戸１０によれば、棒状部材２１が折戸１０の連結部ｃｐに上下方向に沿って、蝶番１５の手前側に介在されているので、手前側から見た状態では、該棒状部材２１によって、戸板１１，１３間の隙間ｇが隠蔽されるとともに蝶番１５も隠蔽される。従って、折戸１０の美観性を効果的に向上することができるとともに、上記隙間ｇにおける指詰めを防止できる。
特に、本参考例では、上記棒状部材２１の長さを、折戸１０の上下方向の略全長に亘って介在される長さとしているので、当該棒状部材２１によって、戸板１１，１３間の隙間ｇ及び蝶番１５の全てが隠蔽され、より美観性が向上される。 As described above, according to the folding door 10 provided with the finger clogging prevention device 20 according to the present reference example , the rod-shaped member 21 is interposed on the front side of the hinge 15 along the connecting portion cp of the folding door 10 in the vertical direction. Therefore, when viewed from the front side, the bar-shaped member 21 conceals the gap g between the door plates 11 and 13 and also conceals the hinge 15. Therefore, the aesthetics of the folding door 10 can be effectively improved and finger filling in the gap g can be prevented.
In particular, in the present reference example , the length of the bar-shaped member 21 is a length that is interposed over substantially the entire length of the folding door 10 in the vertical direction, and therefore the gap g between the door plates 11 and 13 is formed by the bar-shaped member 21. And all of the hinges 15 are concealed, and the aesthetics are further improved.

さらに、上記指詰防止具２０の棒状部材２１は、上述のように、折戸１０の開閉に伴って、該折戸１０の閉動時には、戸板１１，１３の端面１２，１４間の空間ｆｓを手前側に向けて移動する一方、該折戸１０の開動時には、端面１２，１４間の空間ｆｓを背面側に向けて移動する構造とされている。従って、折戸１０の閉動がなされる際に、戸板１１，１３の端面１２，１４間に形成される扇状の上記空間ｆｓを、当該棒状部材２１が手前側に向けて移動するので、当該空間ｆｓに手指が存在している状態においても、該棒状部材２１の手前側への移動によって、手指が該空間ｆｓからはじき出されるようにして、指詰めの防止がなされる。
換言すれば、このような棒状部材２１が設けられていないものでは、上記空間ｆｓが閉動に伴い狭小となるに従って、戸板の連結部側端面が互いに近接し、この空間に閉動時に手指が存在すると、手指が挟みこまれてしまう恐れがあるが、本参考例によれば、そのような恐れを防止できる。 Further, as described above, the bar-shaped member 21 of the finger clogging prevention device 20 opens the space fs between the end surfaces 12 and 14 of the door plates 11 and 13 when the folding door 10 is closed as the folding door 10 is opened and closed. While moving toward the side, when the folding door 10 is opened, the space fs between the end surfaces 12 and 14 is moved toward the back side. Therefore, when the folding door 10 is closed, the bar-shaped member 21 moves toward the front side in the fan-shaped space fs formed between the end surfaces 12 and 14 of the door plates 11 and 13. Even in the state where fingers are present in fs, the fingers are prevented from being stuffed by causing the fingers to be ejected from the space fs by the movement of the rod-shaped member 21 toward the front side.
In other words, in the case where such a rod-shaped member 21 is not provided, as the space fs becomes narrower with the closing movement, the end surfaces on the connecting portion side of the door plates come closer to each other, and fingers are moved to this space when closing. If present, there is a risk that fingers will be pinched, but according to this reference example , such fear can be prevented.

また、本参考例では、上記棒状部材２１は、少なくとも押圧閉動が可能となる状態から、当該折戸１０の閉動がなされて閉止されるまで、その背面側部２３が各戸板１１，１３の各端面１２，１４に当接して、上述のように手前側及び背面側に向けて移動する構造とされているので、各戸板１１，１３の各端面１２，１４と、棒状部材２１との間に隙間が形成されず、指詰めを確実に防止できる。
さらに、上記棒状部材２１の手前側及び背面側への移動は、上記棒状ゴム体２５による背面側への付勢と、折戸１０の閉動に伴う各戸板１１，１３の各端面１２，１４の近接作用によりなされる構成としているので、指詰防止具２０の構成を、簡易な構造とできる。 Further, in the present reference example , the bar-like member 21 has the back side portion 23 of each door plate 11, 13 until the folding door 10 is closed and closed from a state where at least pressing and closing is possible. Since it is configured to abut on each end surface 12, 14 and move toward the near side and the back side as described above, between each end surface 12, 14 of each door plate 11, 13 and the rod-shaped member 21. No gaps are formed in the finger, and it is possible to reliably prevent finger filling.
Further, the movement of the bar-shaped member 21 toward the front side and the back side is caused by the biasing of the bar-shaped rubber body 25 toward the back side and the end surfaces 12, 14 of the door plates 11, 13 accompanying the closing movement of the folding door 10. Since it is set as the structure made by a proximity | contact action, the structure of the finger clogging prevention tool 20 can be made into a simple structure.
