Description

本発明は、住宅の開口部の扉や間仕切り用の扉として、或いは収納装置等の扉として用いることができる折り戸に関する。 The present invention relates to a folding door that can be used as a door for an opening of a house, a door for a partition, or a door of a storage device or the like.

従来の折り戸は、特許文献１にその一例が示されるように、相隣る扉の端面に凹部を設け、この凹部に弾性体を取り付けることにより、扉の連結部の間に手指が挟まったとしても、取り付けた弾性体のクッション作用によって怪我をするのを未然に防ぐようにしたものが知られている。 As shown in Patent Document 1, for example, a conventional folding door is provided with a recess on the end surface of adjacent doors, and an elastic body is attached to the recess, so that fingers are sandwiched between connecting portions of the door. Even so, it is known to prevent injury by the cushioning action of the attached elastic body.

しかしながら、このような折り戸においては、手指が普通に連結部の間に挟まった場合は前記怪我の未然防止効果を発現できると思われるが、手指が万一奥（後側）まで入りこんで挟まったときは、怪我を十分に防止することができなかった。 However, in such a folding door, it is considered that the injury prevention effect can be exhibited when the fingers are normally sandwiched between the connecting portions, but the fingers are caught in the back (rear side) by any chance. Injuries could not be adequately prevented.

特に、扉同士を丁番で折り畳み自在に連結するような場合には、扉同士の後側（丁番側）に狭い隙間が設けられることもあり、このような場合には、この隙間に手指やその一部が万一挟まって怪我をすることがあるという問題を有していた。
実開平４−１１６５８７号 In particular, when the doors are foldably connected with hinges, a narrow gap may be provided on the rear side (the hinge side) of the doors. And some of them could have been injured.
Japanese Utility Model Publication No. 4-116587

本発明は、かかる問題点に鑑みなされたもので、扉の連結部に万一手指が深く入った場合においても、指詰めによる怪我を未然に防止できる折り戸を提供することを目的とする。 The present invention has been made in view of such problems, and it is an object of the present invention to provide a folding door that can prevent injury due to finger jamming even when a finger is deeply inserted into the connecting portion of the door.

上記目的を達成するために、本発明の折り戸は、複数枚の折り戸パネルをヒンジにより折り畳み自在に連結して形成した折り戸において、該折り戸を閉じた状態において、相隣る折り戸パネルの側端面間の水平距離が１３ｍｍ以上となるように折り戸パネル同士を連結するとともに、双方の折り戸パネルの側端面に、左右２つの中空状変形体の後部を軟質樹脂結合部によって折り曲げ自在に結合して形成した目隠し材の上記左右の中空状変形体を、夫々固定してなることを特徴とする。 In order to achieve the above object, a folding door according to the present invention is a folding door formed by connecting a plurality of folding door panels so as to be foldable by hinges, and the folding doors are adjacent to each other when the folding door is closed. The folding door panels are connected to each other so that the horizontal distance between the side end faces of the panels is 13 mm or more, and the rear portions of the two left and right hollow deformable bodies are folded to the side end faces of both folding door panels by the soft resin bonding portion. The left and right hollow deformation bodies of the blindfold formed by freely joining are fixed to each other.

本発明の折り戸は、閉じた状態において、相隣る折り戸パネルの側端面間の水平距離が１３ｍｍ以上となるように広くとり、また、双方の折り戸パネルの側端面に、軟質樹脂結合部によって折り曲げ自在に結合された左右２つの中空変形体からなる目隠し材を固定しているので、折り戸を開いた状態から閉じた状態に操作する途中で、万一折り戸パネルの連結部に手指が挟まった場合でも、折り戸パネルの側端面間の水平距離が広く、且つ挟まった手指を包み込むように左右の柔軟な中空変形体が変形するので、上記挟まった手指が強く圧迫されることがなく、従って、指詰めによる怪我を防止することが出来る。 In the closed state, the folding door of the present invention is wide so that the horizontal distance between the side end surfaces of adjacent folding door panels is 13 mm or more, and the side end surfaces of both folding door panels are soft resin-bonded. Since the blindfold consisting of two left and right hollow deformation bodies that are foldably joined by the part is fixed, the folding door should be connected to the folding door panel during the operation from the opened state to the closed state. Even when a finger is pinched, the horizontal distance between the side end surfaces of the folding door panel is wide, and the left and right flexible hollow deformed bodies are deformed so as to wrap the pinched finger, so that the pinched finger is strongly pressed. Therefore, it is possible to prevent injuries due to finger padding.

また、目隠し材は、左右の中空変形体同士が軟質樹脂結合部によって折り曲げ自在に結合した構成を有しているので、特に、扉同士の後側（丁番側）を丁番で連結し、この連結部の後側（丁番側）に数ｍｍ程度の狭い隙間を設けているような場合であっても、連結部内に手指が深く入り込み、この狭い隙間内に手指やその一部が挟まれるのを目隠し材の軟質樹脂結合部によって防止することができ、このような場合における手指の指詰めによる怪我も防止することができる。 In addition, since the blindfold has a configuration in which the left and right hollow deformable bodies are foldably coupled by the soft resin coupling portion, in particular, the rear side of the doors (the hinge side) is connected by a hinge, Even when a narrow gap of about several millimeters is provided on the rear side (the hinge side) of this connecting part, the fingers enter deeply into the connecting part, and fingers or a part thereof are sandwiched in this narrow gap. This can be prevented by the soft resin bonding portion of the blindfold, and injuries due to finger clogging in such a case can also be prevented.

また、相隣る折り戸パネルの連結部間を覆うように上記目隠し材が固定されるので、隙間やヒンジが外部から見えることがなく、折り戸の外観を良くすることができる。 Moreover, since the said blindfold is fixed so that the connection part of adjacent folding door panels may be covered, a clearance gap and a hinge are not visible from the outside, and the external appearance of a folding door can be improved.

以下、本発明を実施するための実施形態を図面に基づき説明する。尚、本発明は本実施形態の記載内容に限られるものではない。 DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. Note that the present invention is not limited to the description of the present embodiment.

図１は、本実施形態に係る折り戸Ａの、折り戸Ａを閉じた状態における水平方向部分断面図である。折り戸Ａは、折り戸パネル１と２の後側をヒンジである蝶番３により折り畳み自在に連結され、そして、この折り戸パネル１と２の側端面の間の水平距離ｗは、１３ｍｍ以上、本実施形態では、２０ｍｍとなるように設定されており、更に、双方の折り戸パネル１、２の側端面には、指詰め防止効果のある目隠し材４が固定されて構成されている。 FIG. 1 is a horizontal partial sectional view of the folding door A according to the present embodiment in a state in which the folding door A is closed. The folding door A is foldably connected to the rear side of the folding door panels 1 and 2 by a hinge 3 as a hinge, and the horizontal distance w between the side end surfaces of the folding door panels 1 and 2 is 13 mm or more, In this embodiment, it is set to be 20 mm, and the blindfold material 4 having a finger padding preventing effect is fixed to the side end surfaces of both the folding door panels 1 and 2.

ここにおいて、上記水平距離ｗは１３ｍｍ未満となると、手指を挟んだ状態で折り戸を閉じた場合、手指が強く圧迫されて怪我をする可能性があるので１３ｍｍ以上とする必要がある。また、上記水平距離ｗは３０ｍｍを超えると、折り戸Ａにおける折り戸パネル１、２の連結部の外観を損なうことがあるので好ましくない。怪我の防止と装飾性の良い外観の観点から、上記水平距離ｗは、１５ｍｍ〜２５ｍｍの範囲にあることが最も好ましい。 Here, if the horizontal distance w is less than 13 mm, the finger may be strongly pressed and injured when the folding door is closed with the finger sandwiched therebetween, so it is necessary to make it 13 mm or more. Moreover, when the said horizontal distance w exceeds 30 mm, since the external appearance of the connection part of the folding door panels 1 and 2 in the folding door A may be impaired, it is unpreferable. The horizontal distance w is most preferably in the range of 15 mm to 25 mm from the viewpoint of injury prevention and good decorative appearance.

また、折り戸パネル１、２としては種々のものを用いることができる。例えば、基板と化粧材とで形成され、基板に、合板、ＬＶＬ、パーティクルボード、ＭＤＦ、集成材、木材或いはそれらの複合物等の木質材料や、火山性ガラス質複層板、珪酸カルシウム板等の無機質板、或いは金属板等を用い、その表面を覆う化粧材に、突板、合成樹脂化粧シート、化粧紙、塗料膜、Ｖカット化粧板（薄い合板等の基材表面に化粧シートを貼着し、裏面側にＶ溝などの折り曲げ溝を設けた化粧板）を用いたもの等を挙げることができる。 Various types of folding door panels 1 and 2 can be used. For example, it is formed of a substrate and a decorative material, and the substrate is made of wood material such as plywood, LVL, particle board, MDF, laminated wood, wood or a composite thereof, volcanic glassy multilayer board, calcium silicate board, etc. Using an inorganic plate or metal plate, a veneer, synthetic resin decorative sheet, decorative paper, paint film, V-cut decorative plate (a decorative sheet is pasted on the surface of a thin plywood substrate, etc.) And the like using a decorative board provided with a bending groove such as a V-groove on the back surface side.

また、蝶番３は、折り戸パネル１，２の後側の側縁部を欠き込んで埋設する埋設タイプのものを用いると折り戸Ａの外観を良くすることができるが、折り戸パネル１，２の後側の側縁面に跨るように直接固定する露出タイプのものを用いることもでき、また蝶番ではなく、折り戸パネル１、２を折り畳み自在に連結することができるものであればヒンジとして用いることができる。 Further, the hinge 3 can improve the appearance of the folding door A by using a buried type in which the rear edge of the folding door panels 1 and 2 is cut out and embedded. It is also possible to use an exposed type that is directly fixed so as to straddle the rear side edge surface of the rear panel 2, and a hinge that can foldably connect the folding door panels 1 and 2 instead of a hinge. Can be used as

目隠し材４は、図２に示すように、左右の中空変形体５、５’がその後部において軟質樹脂結合部７によって折り畳み自在に結合された構成を有している。 As shown in FIG. 2, the blindfold 4 has a configuration in which left and right hollow deformable bodies 5, 5 ′ are foldably joined by a soft resin joint 7 at the rear part.

ここにおいて左右の中空変形体５、５’は、傾斜面の前面部６ａと側面部６ｂと後面部６ｃとで形成される軟質樹脂製変形部６と、折り戸パネル１、２の側端面に当接する硬質樹脂製支持部９と、該硬質樹脂製支持部９の央部から略垂直に突接し、折り戸パネル１、２の側端部内に夫々固定される硬質樹脂製取り付け部８、８とで構成されている。 Here, the left and right hollow deformable bodies 5, 5 ′ are formed on the side end surfaces of the soft resin deformed portion 6 formed by the front surface portion 6a, the side surface portion 6b, and the rear surface portion 6c of the inclined surface, and the folding door panels 1 and 2. The hard resin support portion 9 that abuts, and the hard resin attachment portions 8 and 8 that are substantially perpendicularly contacted from the central portion of the hard resin support portion 9 and are respectively fixed in the side end portions of the folding door panels 1 and 2. It consists of and.

軟質樹脂結合部７は、上記左右の中空変形体５、５’を折り畳み自在に結合できる柔軟度の樹脂や形状を有しているものを使用でき、形状としてはシート状、帯板状、断面円盤状など種々のものを用いることができる。 The soft resin joint portion 7 can be made of a flexible resin or shape that can be foldably joined to the left and right hollow deformable bodies 5 and 5 '. Various things, such as a disk shape, can be used.

目隠し材４は、このように、左右２つの中空変形体５、５’が、軟質樹脂結合部７によって結合されているので、折り畳み自在であるとともに、左右の中空変形体５、５’の夫々の軟質樹脂製変形部６は、外圧に適応して任意形状に容易に変形するように形成されている。尚、このような目隠し材４は、硬質樹脂と軟質樹脂を組み合わせて形成されているため、押し出し成形等により容易に製造することができるので、好適に用いることができる。 The blindfold 4 is thus foldable since the two left and right hollow deformable bodies 5 and 5 ′ are joined by the soft resin joint portion 7, and the left and right hollow deformable bodies 5 and 5 ′ are respectively foldable. The soft resin deforming portion 6 is formed so as to be easily deformed into an arbitrary shape in accordance with an external pressure. In addition, since such a blinding material 4 is formed by combining a hard resin and a soft resin, it can be easily used by extrusion molding or the like, and therefore can be suitably used.

また、傾斜面の前面部６ａと側面部６ｂと後面部６ｃとで形成される軟質樹脂製変形部６や軟質樹脂結合部７は、折り戸Ａの開閉時に外部に露出して目視できる部分であるので、樹脂着色、コーティング、転写印刷その他の方法で装飾し、連結部の外観を向上させておくことができる。 Further, the soft resin deformed portion 6 and the soft resin joint portion 7 formed by the front surface portion 6a, the side surface portion 6b, and the rear surface portion 6c of the inclined surface are portions that are exposed to the outside and visible when the folding door A is opened and closed. Therefore, it can be decorated by resin coloring, coating, transfer printing, or other methods to improve the appearance of the connecting portion.

次に、図３乃至図５に基づいて本実施形態に係る折り戸Ａの指詰め防止効果を説明する。図３は折り戸パネル１を１８０°折り曲げて、折り戸Ａを開にした状態を示す説明図、図４は、折り戸Ａを開から閉に操作する時に手指が挟まる状態を示す説明図、図５は、折り戸Ａを閉にした時に手指が挟まった状態を示す説明図である。 Next, the finger padding prevention effect of the folding door A according to the present embodiment will be described based on FIGS. 3 to 5. FIG. 3 is an explanatory view showing a state in which the folding door panel 1 is folded 180 ° and the folding door A is opened, and FIG. 4 is an explanatory view showing a state in which fingers are pinched when the folding door A is operated from opening to closing. FIG. 5 is an explanatory diagram showing a state where fingers are pinched when the folding door A is closed.

図３に示すように、折り戸Ａを操作して折り戸パネル１、２を完全に折り畳むことにより、折り戸Ａを開いた状態にすることができる。この時、目隠し材４の軟質樹脂製変形部６と軟質樹脂結合部７は、外に露出した状態になる。そして軟質樹脂結合部７によって、蝶番３や折り畳まれた折り戸パネル１、２の間の隙間１０が外部から見えて外観を損なうことがない。 As shown in FIG. 3, the folding door A can be opened by operating the folding door A and completely folding the folding door panels 1 and 2. At this time, the soft resin deforming portion 6 and the soft resin joint portion 7 of the blindfold 4 are exposed to the outside. And by the soft resin coupling | bond part 7, the clearance gap 10 between the hinge 3 or the folded folding door panels 1 and 2 can be seen from the exterior, and an external appearance is not impaired.

次に折り戸Ａを閉じる方向に操作して、図４に示すように途中まで閉じた状態にする。この時に、図４に示すように、目隠し材４の軟質樹脂製変形部６に囲われた連結部内に手指が入り込むことがある。 Next, the folding door A is operated in the closing direction so that it is closed halfway as shown in FIG. At this time, as shown in FIG. 4, a finger may enter the connecting portion surrounded by the soft resin deforming portion 6 of the blindfold 4.

次に連結部内に手指が入り込んだ状態で、図５に示すように折り戸Ａを完全に閉じると、目隠し材４の軟質樹脂製変形部６の間に手指が挟まれる。この時、折り戸パネル１と２の側端面の間の水平距離ｗを、本実施形態では、一般人の指巾よりも大きな寸法の２０ｍｍとするとともに、手指に接する目隠し材４の中空変形体５の軟質樹脂製変形部６が手指の形状に沿って柔軟に変形するので、挟まれた手指が強く圧迫されて怪我をするということがない。 Next, when the folding door A is completely closed as shown in FIG. 5 in a state where the fingers have entered the connecting portion, the fingers are sandwiched between the soft resin deforming portions 6 of the blindfold 4. At this time, in this embodiment, the horizontal distance w between the side end surfaces of the folding door panels 1 and 2 is set to 20 mm, which is larger than the finger width of an ordinary person, and the hollow deformation body 5 of the blindfold 4 that contacts the fingers. Since the soft resin deforming portion 6 deforms flexibly along the shape of the finger, the pinched finger is not strongly pressed and injured.

図６は、別の実施形態に係る折り戸Ｂにおいて手指が連結部内に入り込んだ状態を示す説明図である。この折り戸Ｂは、折り戸パネル１’、２’の連結部の後側（蝶番３側）の隙間が数ｍｍ以上の大きめの隙間１０’である場合で、この大きめの隙間１０’を、目隠し材４の軟質樹脂結合部７が覆うように構成されている。その他の構成は、折り戸Ａと同じである。 Drawing 6 is an explanatory view showing the state where a finger entered into a connecting part in folding door B concerning another embodiment. This folding door B is a case where the gap on the rear side (hinge 3 side) of the connecting portion of the folding door panels 1 'and 2' is a large gap 10 'of several mm or more. It is comprised so that the soft resin coupling | bond part 7 of the blindfold material 4 may cover. Other configurations are the same as those of the folding door A.

このため、折り戸Ｂにおいては、連結部内に深く入り込んだ手指或いはその一部が上記隙間１０’に入り込もうとしても、この隙間１０’を覆うように目隠し材４の軟質樹脂結合部７が取り付けられているため、その入り込みを確実に防止することができる。従って、折り戸Ｂを完全に閉じる状態にしても、隙間１０’内に手指やその一部が挟まれることはなく、前記折り戸Ａの場合と同様に、目隠し材４の軟質樹脂製変形部６の間に手指が挟まれるが、折り戸パネル１’と２’の側端面の間の水平距離ｗを、一般人の指巾より大きめの２０ｍｍとするとともに、手指に接する目隠し材４の中空変形体５の軟質樹脂製変形部６が手指の形状に沿って柔軟に変形するので、挟まれた手指が強く圧迫されて怪我をするということがない。 For this reason, in the folding door B, even if a finger or a part of the finger that has entered deeply into the connecting portion tries to enter the gap 10 ′, the soft resin coupling portion 7 of the blindfold 4 is attached so as to cover the gap 10 ′. Therefore, the entry can be reliably prevented. Therefore, even if the folding door B is completely closed, fingers and parts thereof are not sandwiched in the gap 10 ', and the soft resin deformed portion of the blindfold 4 is similar to the case of the folding door A. A finger is sandwiched between 6 and the horizontal distance w between the side end surfaces of the folding door panels 1 ′ and 2 ′ is set to 20 mm, which is larger than the finger width of a general person, and the hollow deformation of the blindfold 4 in contact with the fingers Since the soft resin deforming portion 6 of the body 5 is flexibly deformed along the shape of the finger, the pinched finger is not strongly pressed and injured.
