Description

本発明は、合成樹脂製の枠体に、合成樹脂製の障子を面内方向に移動自在に建て込んだ合成樹脂製サッシに関する。 The present invention relates to a synthetic resin sash in which a synthetic resin shoji is built in a synthetic resin frame so as to be movable in an in-plane direction.

従来から合成樹脂製の上枠、下枠、左右の縦枠を方形状に連結した合成樹脂製の枠体に、合成樹脂製の上框、下框、戸当り框、召合せ框を方形状に連結した框体内にガラスを装着した合成樹脂製の障子を、面内方向に移動自在に建て込んだ合成樹脂製サッシが種々提案されている。
この合成樹脂製の枠体、障子の框体は、例えば特許文献１に開示されたように、各枠、各框の長手方向端部を４５度に切断加工し、その切断した端面をつき合わせて熱溶着により圧着して連結することで枠体、框体としている。 Conventionally, synthetic resin upper frame, lower frame, door-to-door frame, and summoned frame are rectangular on the synthetic resin frame that connects the upper frame, lower frame, and left and right vertical frames of synthetic resin in a square shape. Various synthetic resin sashes have been proposed in which a synthetic resin shoji with glass mounted in a casing connected to is movably mounted in the in-plane direction.
For example, as disclosed in Patent Document 1, the synthetic resin frame and shoji frame are cut at 45 degrees in the longitudinal direction of each frame and each frame, and the cut end surfaces are brought together. In this way, the frame and the housing are formed by pressure bonding by thermal welding.

また、前述した合成樹脂製サッシにおいては、障子の上框、下框、戸当り框と枠体の上枠、下枠、縦枠の見付け方向（上下方向、左右方向）の重なり寸法（例えば、のみ込み寸法）を大きくし、サッシとしての耐風圧性能や気密・水密性能を確保している。
例えば、特許文献２に開示したように、上枠、下枠、縦枠を、その内面に複数の内向突部を設け、上框、下框、戸先框の見付け方向外端部に外向突部を設け、この外向突部と前記内向突部を見付け方向に重なり合うようにして障子を枠体に建て込んでいる。

Japanese Utility Model Publication No. 5-32678 Japanese Patent No. 3177910

前記合成樹脂製の障子の框を、前述したように熱溶着で連結するために、従来は障子の上框、下框、戸当り框、召合せ框を同一断面形状としている。
また、前述したように、上枠、下枠、縦枠と上框、下框、戸当り框の見付け方向の重なり寸法を大きくした合成樹脂製サッシにおいては、その上框、下框、戸当り框の見付け寸法（上下方向の寸法、左右方向の寸法）は外向突部のために大きい。 In order to connect the above-mentioned synthetic resin shoji ridges by heat welding as described above, conventionally, the upper ledge, lower heel, door-to-door folds, and summon folds of the shoji have the same cross-sectional shape.
In addition, as mentioned above, in the case of synthetic resin sash with a large overlapping dimension in the direction of finding the upper frame, lower frame, vertical frame and upper frame, lower frame, and door block, the upper frame, lower frame, and door block The heel finding dimensions (vertical and horizontal dimensions) are large due to outward projections.

このようであるから、框を熱溶着で連結した障子とすると共に、枠と框の見付け方向の重なり寸法を大きくした合成樹脂製サッシにおいては、障子の召合せ框が上框、下框、戸当り框と同一断面形状で、その召合せ框の見付け寸法が大きく、室内から見た時に見付け寸法の大きな召合せ框全体が見え、内観の見栄えが悪い。 In this way, in the synthetic resin sash with the sash connected by thermal welding, and the overlap size in the direction of finding the frame and the heel, It has the same cross-sectional shape as the hitting bowl, and the size of the summon bowl is large. When viewed from the room, the whole summit bowl with a large spot size can be seen, and the interior appearance is poor.

また、上框、下框、戸当り框が、見付け方向外端部に外向突部を有する断面形状であると、召合せ框も見付け方向外端部に外向突部を有する断面形状であるから、その召合せ框の見付け方向外端部にクレセントなどの施錠部品を取付けることが困難で、その召合せ框の見付け方向外端部にカバー材を取付け、そのカバー材に施錠部品を取付けているので、コスト高である。 Also, if the upper bowl, the lower bowl, and the door-to-door fence have a cross-sectional shape having an outward projection at the outer end in the direction of finding, the summon bowl also has a sectional shape having an outward projection at the outer end in the direction of finding. It is difficult to attach a locking part such as a crescent to the outer end of the summon bowl in the direction of finding, and a cover material is attached to the outer end of the summit bowl in the direction of finding, and a locking part is attached to the cover material. So the cost is high.

本発明の目的は、框を熱溶着で連結して障子の框体を形成できると共に、上枠、下枠、縦枠と上框、下框、戸当り框の見付け方向の重なり寸法を大きくでき、しかも内観の見栄えが良いと共に、召合せ框の見付け方向外端部に施錠部品をカバー材を用いずに取付けできるようにした合成樹脂製サッシとすることである。 The object of the present invention is to form the shoji frame by connecting the coffins by heat welding and to increase the overlapping dimension of the upper frame, the lower frame, the vertical frame and the upper coffin, the lower coffin, and the door coffin in the direction of finding. In addition, it is a synthetic resin sash that has a good interior appearance and that allows the locking parts to be attached to the outer end of the summon bowl in the direction in which it is found without using a cover material.

本発明は、合成樹脂製の上枠、下枠及び左右縦枠を方形状に連結し、その内面に内向突部を備えた枠体に、合成樹脂製の上框、下框、戸当り框及び召合せ框を方形状に連結した框体から成る障子を面内方向に移動自在に建て込んだ合成樹脂製サッシであって、
前記上框、下框及び戸当り框は、ガラス装着部を有した本体と、その本体の見付け方向外端部に外向突部を備えた同一断面形状で、
前記召合せ框は、前記上框、下框及び戸当り框における外向突部を備えていない本体と同様な断面形状とし、
前記上框、下框及び戸当り框は、長手方向の端面をそれぞれ４５度の傾斜面とし、その端面同士を突き合わせて熱溶着で連結し、
前記上框、下框及び召合せ框は、上框、下框の本体と召合せ框の長手方向の端面をそれぞれ４５度の傾斜面とし、その端面同士を突き合わせて熱溶着で連結し、
前記障子は前記枠体に、前記上框、下框の外向突部が前記上枠、下枠の内向突部に見付け方向に重なり合うように建て込まれ、障子を閉じた状態で前記戸当り框の外向突部が前記縦枠の内向突部に見付け方向に重なり合うようにしたことを特徴とする合成樹脂製サッシである。 The present invention connects a synthetic resin upper frame, a lower frame, and left and right vertical frames in a rectangular shape, and has a frame having an inward projection on the inner surface thereof. And a sash made of synthetic resin in which a shoji made of a box in which summons are connected in a rectangular shape is movably built in the in-plane direction,
The upper gutter, lower gutter and door-to-door eaves have the same cross-sectional shape with a main body having a glass mounting portion and an outward projecting portion at the outer end portion in the finding direction of the main body,
The summon bowl has a cross-sectional shape similar to that of the main body that does not have outward projections in the upper, lower, and door-to-door fences,
The upper heel, the lower heel and the door heel are each inclined at 45 degrees in the longitudinal direction, the end surfaces are butted together and connected by thermal welding,
The upper bowl, the lower bowl, and the summon bowl are each 45 degrees inclined surfaces of the upper bowl, the lower bowl body and the summit bowl, and the end faces are butted together and connected by thermal welding,
The sliding door is built in the frame body so that the outward projections of the upper and lower collars overlap the inward projections of the upper and lower frames in the direction of finding, and the door sliding fence is closed with the shoji closed. The synthetic resin sash is characterized in that the outward projecting portion of the vertical frame overlaps the inward projecting portion of the vertical frame in the finding direction.

本発明においては、上框、下框及び戸当り框は、その本体の室内側部が外向突部よりも室内側に張り出した形状で、その各本体の室内側張り出し部と召合せ框が同一見付け寸法で四周連続しているようにできる。
このようにすれば、室内から見た時に、見付け寸法が小さな召合せ框、上框、下框、戸当り框の本体における室内側張り出し部が四周連続して目立つので、内観がスリムでスッキリとした見栄えの良いものとなる。 In the present invention, the upper heel, the lower heel and the door ledge are shaped so that the indoor side portion of the main body protrudes to the indoor side from the outward projection, and the indoor side protruding portion of each main body is the same as the summoning ridge. It can be made to be four consecutive rounds at the found dimensions.
In this way, when viewed from the inside, the indoor side overhanging part of the body of the summon bowl, upper bowl, lower bowl, and door-to-door bowl with small dimensions is conspicuous for four rounds, so the interior is slim and refreshing. Will look good.

本発明においては、障子が閉じた状態において、戸当り框の本体の室内側張り出し部と縦枠との間に人の手が入り込む隙間が生じるようにできる。
このようにすれば、戸当り框の本体の室内側張り出し部を手掛けとして障子を容易に開放操作できる。 In the present invention, in a state in which the shoji is closed, a gap in which a human hand enters can be formed between the indoor side overhanging portion of the main body of the door-to-door fence and the vertical frame.
In this way, the shoji can be easily opened using the indoor side overhanging portion of the main body of the door-to-door fence.

本発明においては、召合せ框に、上框、下框の外向突部の長手方向の端面を被覆する覆部材を取付けることができる。
このようにすれば、上框、下框の外向突部の長手方向の端面が露出しないようにできる。 In the present invention, a covering member that covers end faces in the longitudinal direction of the outward protrusions of the upper bowl and the lower bowl can be attached to the summon bowl.
In this way, it is possible to prevent the end faces in the longitudinal direction of the outward projections of the upper and lower eyelids from being exposed.

本発明によれば、上框、下框と戸当り框を熱溶着で連結すると共に、上框、下框の本体と召合せ框を熱溶着で連結したので、框を熱溶着で連結して障子の框体を形成できる。
また、上框、下框、戸当り框の本体に設けた外向突部が上枠、下枠、縦枠の内向突部に見付け方向に重なり合うので、その見付け方向の重なり寸法を大きくできる。
また、召合せ框は上框、下框、戸当り框の外向突部を備えていない本体と同様な断面形状であるから、その見付け寸法が小さく、内観の見栄えが良い。
また、召合せ框の見付け方向外端部を、凹凸の無い平坦面とすることができるから、その召合せ框の見付け方向外端部に、施錠部品をカバー材を用いずに取付けできる。 According to the present invention, the upper heel, the lower heel and the door heel are connected by thermal welding, and the upper heel and lower heel main body and the summon heel are connected by thermal welding, so the heel is connected by thermal welding. A shoji frame can be formed.
Moreover, since the outward protrusion provided on the main body of the upper, lower, and door-to-door overlaps with the inward protrusion of the upper frame, the lower frame, and the vertical frame in the direction of detection, the overlapping dimension in the direction of detection can be increased.
In addition, the summon bowl has the same cross-sectional shape as the main body that does not have the outward projections of the upper bowl, the lower bowl, and the door-to-door bowl, so that its size is small and the interior appearance is good.
In addition, since the outer end portion in the direction of finding the summon basket can be a flat surface without unevenness, the locking part can be attached to the outer end portion in the direction of finding the summon basket without using a cover material.

図１と図２に示すように、枠体１は、合成樹脂製の上枠１０と下枠１１と左右の縦枠１２を方形状に連結した合成樹脂製である。
この枠体１内に面内方向に移動自在に建て込んだ障子２は、合成樹脂製の上框２０と下框２１と戸当り框２２と召合せ框２３を方形状に連結した框体２４内にガラス２５を装着した合成樹脂製である。
この実施の形態では、枠体１の室内側寄りと室外側寄りに障子２が面内方向に移動自在で、引き違いにそれぞれ建て込んであり、合成樹脂製引き違いサッシとしてある。
前記面内方向とは上枠１０、下枠１１の長手方向に沿った方向である。
なお、室外側寄りに建て込んだ障子２を固定して嵌め殺し部とし、室内側寄りに建て込んだ障子２を移動するようにしても良い。 As shown in FIGS. 1 and 2, the frame 1 is made of synthetic resin in which a synthetic resin upper frame 10, lower frame 11, and left and right vertical frames 12 are connected in a square shape.
A shoji 2 which is built in the frame 1 so as to be movable in the in-plane direction is a box 24 in which a synthetic resin upper cage 20, lower cage 21, door-to-door cage 22 and summing cage 23 are connected in a square shape. It is made of synthetic resin with a glass 25 inside.
In this embodiment, the shoji 2 is movable in the in-plane direction toward the indoor side and the outdoor side of the frame body 1 and is built in the difference, and is a synthetic resin difference sash.
The in-plane direction is a direction along the longitudinal direction of the upper frame 10 and the lower frame 11.
In addition, the shoji 2 built in the outdoor side may be fixed and used as a fitting killing part, and the shoji 2 built in the indoor side may be moved.

前記上枠１０、下枠１１、縦枠１２は、図３、図４に示すように、本体３０の内面３０ａに複数の内向突部を室内外側方向に間隔を置いて有した同一断面形状の形材を用いている。前記内面３０ａとは見付け方向（上下方向、左右方向）における障子２と対向した内側の面である。
例えば、室内側内向突部３１、室内側寄り中間内向突部３２、室外側寄り中間突部３３、室外側内向突部３４を有している。
前記室内側内向突部３１と室内側寄り中間内向突部３２との間に第１溝３５、室内側寄り中間内向突部３２と室外側寄り中間内向突部３３との間に第２溝部３６、室外側寄り中間内向突部３３と室外側内向突部３４との間に第３溝部３７をそれぞれ形成している。
この第１・第２・第３溝部３５，３６，３７は内方に開口している。
前記上枠１０と縦枠１２、下枠１１と縦枠１２は、各長手方向の端面を、切断などによって４５度の傾斜面とし、その端面同士を突き合わせて熱溶着で連結している。 As shown in FIGS. 3 and 4, the upper frame 10, the lower frame 11, and the vertical frame 12 have a plurality of inward protrusions on the inner surface 30 a of the main body 30 with the same cross-sectional shape spaced apart from each other in the interior / exterior direction. The shape is used. The inner surface 30a is an inner surface facing the shoji 2 in the finding direction (vertical direction, horizontal direction).
For example, it has an indoor inward protrusion 31, an indoor inward intermediate protrusion 32, an outdoor outward intermediate protrusion 33, and an outdoor inward protrusion 34.
A first groove 35 is formed between the indoor-side inward protrusion 31 and the indoor-side intermediate inward protrusion 32, and a second groove 36 is formed between the indoor-side intermediate inward protrusion 32 and the outdoor-side intermediate inward protrusion 33. A third groove 37 is formed between the intermediate inward projection 33 near the outdoor side and the outdoor inward projection 34.
The first, second, and third groove portions 35, 36, and 37 are opened inward.
The upper frame 10 and the vertical frame 12, and the lower frame 11 and the vertical frame 12 have end surfaces in the longitudinal direction formed into inclined surfaces of 45 degrees by cutting or the like, and the end surfaces are butted together and connected by heat welding.

この実施の形態では、本体３０の室内側面３０ｂと室内側内向突部３１の室内側面３１ａが面一に連続し、室内から見た時に枠体１の室内側面がフラットな１つの面として見える。
また、前記室外側内向突部３４の室外側面３４ａは前記本体３０の室外側面３０ｃよりも室内側寄りである。そして、上枠１０、下枠１１の本体３０の内面３０ａにおける室外側内向突部３４よりも室外寄り部分に網戸レール３８が取付けてある。
前記本体３０は中空部を有する形状で、その中空部に金属製の補強部材３９を挿入している。
前記上枠１０、下枠１１、縦枠１２は前述の形状に限ることはない。 In this embodiment, the indoor side surface 30b of the main body 30 and the indoor side surface 31a of the indoor-side inward projection 31 are flush with each other, and the indoor side surface of the frame 1 can be seen as one flat surface when viewed from the room.
Further, the outdoor side surface 34 a of the outdoor side inward projection 34 is closer to the indoor side than the outdoor side surface 30 c of the main body 30. A screen door rail 38 is attached to a portion of the inner surface 30a of the main body 30 of the upper frame 10 and the lower frame 11 that is closer to the outdoor side than the outdoor inward projection 34.
The main body 30 has a shape having a hollow portion, and a metal reinforcing member 39 is inserted into the hollow portion.
The upper frame 10, the lower frame 11, and the vertical frame 12 are not limited to the shapes described above.

前記上框２０、下框２１、戸当り框２２は、本体４０と、その本体４０の見付け方向外端面４０ａに設けた前記上枠１０、下枠１１、縦枠１２の内向突部と見付け方向に重なり合う外向突部を有し、本体４０の見付け方向内端部にガラス装着部４１を有した同一断面形状である。
例えば、本体４０の見付け方向外端面４０ａに室内側外向突部４２と室外側外向突部４３を一体的に設けてある。
前記本体４０の見付け方向内端面４０ｂに内向ガラス支持部４４を一体的に設けると共に、押縁４５を取付けて内向溝部を形成し、その内向溝部をガラス装着部４１とする。 The upper rod 20, the lower rod 21, and the door rod 22 are the main body 40 and the inward protrusions of the upper frame 10, the lower frame 11, and the vertical frame 12 provided on the outer end surface 40a of the main body 40 and the direction of the main frame 40. The same cross-sectional shape has an outward projecting portion that overlaps with each other, and has a glass mounting portion 41 at the inner end portion in the direction of finding the main body 40.
For example, the indoor-side outward projection 42 and the outdoor-side outward projection 43 are integrally provided on the outer end surface 40a in the direction of finding the main body 40.
An inward glass support portion 44 is integrally provided on the inner end surface 40b in the finding direction of the main body 40, and an inward groove portion is formed by attaching a pressing edge 45, and the inward groove portion is referred to as a glass mounting portion 41.

前記召合せ框２３は、本体４０と、その本体４０の見付け方向内端部に設けたガラス装着部４１を有している。
前記ガラス装着部４１は、前記本体４０の見付け方向内端面４０ｂに内向ガラス支持部４４を一体的に設けると共に、押縁４５を取付けて内向溝部としてある。
すなわち、召合せ框２３のガラス装着部４１と上框２０、下框２１、戸当り框２２のガラス装着部４１は同一断面形状で、召合せ框２３の本体４０は上框２０、下框２１、戸当り框２２の本体４０と同様な断面形状である。要するに召合せ框２３は上框２０、下框２１、戸当り框２２における外向突部を備えていない本体４０と同様な断面形状である。
なお、召合せ框２３の本体４０は、見付け方向外端面４０ａと連続した見込み方向（室内外側方向）に向かう突片４６を有しているので、断面形状は上框２０、下框２１、戸当り框２２の本体４０の断面形状とは同一ではないが、後述するように熱溶着して連結する部分の外周形状は同一であるので、同様の断面形状と表現する。この突片４６は無くとも良く、その場合には同一の断面形状となるが、前述の同様の断面形状は同一の断面形状を含むものとする。すなわち、同様な断面形状とは端面同士を正しく突き合わせできる形状である。 The summoning bowl 23 has a main body 40 and a glass mounting portion 41 provided at the inner end of the main body 40 in the direction of finding.
The glass mounting portion 41 is provided with an inward glass support portion 44 integrally on the inner end surface 40b in the finding direction of the main body 40, and has a pressing edge 45 as an inward groove portion.
That is, the glass mounting portion 41 of the summoning bowl 23 and the upper and lower bowls 20 and 21 and the glass mounting section 41 of the door-to-bottom bowl 22 have the same cross-sectional shape, and the main body 40 of the summoning bowl 23 is the upper bowl 20 and the lower bowl 21. The cross-sectional shape is the same as that of the main body 40 of the door cage 22. In short, the summoning bowl 23 has a cross-sectional shape similar to that of the main body 40 that does not have outward projections in the upper bowl 20, the lower bowl 21, and the door-to-door fence 22.
The main body 40 of the summoning bowl 23 has a projecting piece 46 that faces the prospective direction (inside of the room) continuous with the outer end face 40a in the finding direction, so that the cross-sectional shape is the upper bowl 20, the lower bowl 21, the door Although the cross-sectional shape of the main body 40 of the contact rod 22 is not the same, the outer peripheral shape of the portion to be connected by heat welding is the same as will be described later, and therefore, it is expressed as a similar cross-sectional shape. The protruding piece 46 may be omitted, and in this case, the same cross-sectional shape is used. However, the same cross-sectional shape described above includes the same cross-sectional shape. That is, a similar cross-sectional shape is a shape that allows end faces to be correctly matched.

前記上框２０と戸当り框２２、下框２１と戸当り框２２は、図５に示すように、上框２０、下框２１、戸当り框２２の長手方向の端面２０ａ，２１ａ，２２ａを、切断などによって４５度の傾斜面とし、その端面同士を突き合わせて熱溶着で連結している。
このようであるから、上框２０、下框２１と戸当り框２２は、本体４０の端面４０ｃと外向突部（室内側外向突部４２、室外側向突部４３）の端面４２ａ，４３ａがそれぞれ熱溶着で連結され、熱溶着で連結される部分の面積が大きく、強固に連結できる。
この実施の形態では、内向ガラス支持部４４の端面４４ａも熱溶着で連結される。 As shown in FIG. 5, the upper rod 20 and the door rod 22 and the lower rod 21 and the door rod 22 have end faces 20 a, 21 a and 22 a in the longitudinal direction of the upper rod 20, the lower rod 21 and the door rod 22. The inclined surfaces are 45 degrees by cutting or the like, and the end surfaces are butted together and connected by heat welding.
Thus, the upper rod 20, the lower rod 21, and the door rod 22 have the end surface 40c of the main body 40 and the end surfaces 42a and 43a of the outward projections (the indoor-side outward projection 42 and the outdoor-side projection 43). Each area is connected by heat welding, and the area of the parts connected by heat welding is large and can be firmly connected.
In this embodiment, the end surface 44a of the inward glass support portion 44 is also connected by heat welding.

前記召合せ框２３と上框２０、下框２１は、図５に示すように、上框２０、下框２１の本体４０の長手方向の端面４０ｃと召合せ框２３の長手方向の端面（本体４０の端面４０ｃ）を、切断などで４５度の傾斜面とし、その端面同士を突き合わせて熱溶着で連結している。
この実施の形態では、上框２０、下框２１の外向突部（室内側外向突部４２、室外側外向突部４３）の長手方向の端面４２ａ，４３ａは、長手方向と直角で、召合せ框２３の本体４０の見付け方向外端面４０ａと面一に連続しているので、障子の見栄えが良い。
また、内向ガラス支持部４４の端面４４ａも熱溶着で連結される。
また、各本体４０は中空部を有し、その中空部に金属製の補強部材４７を挿入している。 As shown in FIG. 5, the summing bowl 23, the upper bowl 20, and the lower bowl 21 are composed of a longitudinal end face 40 c of the main body 40 of the upper bowl 20 and the lower bowl 21 and a longitudinal end face (main body of the summing bowl 23). 40 end surfaces 40c) are inclined by 45 degrees by cutting or the like, and the end surfaces are butted together and connected by thermal welding.
In this embodiment, the longitudinal end faces 42a and 43a of the outward projections of the upper rod 20 and the lower rod 21 (the indoor-side outward projection 42 and the outdoor-side outward projection 43) are perpendicular to the longitudinal direction. Since the main body 40 of the ridge 23 is continuous with the outer end surface 40a in the direction of finding, the shoji looks good.
Moreover, the end surface 44a of the inward glass support part 44 is also connected by heat welding.
Each main body 40 has a hollow portion, and a metal reinforcing member 47 is inserted into the hollow portion.

前述のようであるから、框を熱溶着で連結して障子２の框体２４を形成できる。
なお、框体２４を形成する時には押縁４５を外しておき、框体２４を形成した後にガラス２５を装着し、その後に押縁４５を取付けする。 Since it is as above-mentioned, the cage | basket 24 of the shoji 2 can be formed by connecting a cage | basket by heat welding.
Note that when the casing 24 is formed, the pressing edge 45 is removed, the glass 25 is attached after the casing 24 is formed, and then the pressing edge 45 is attached.

前記障子２を枠体１に建て込むことで、上框２０、下框２１の外向突部が上枠１０、下枠１１の内向突部と見付け方向に重なり合い、障子２を閉じた状態とすることで戸当り框２２の外向突部が縦枠１２の内向突部に見付け方向に重なり合う。
例えば、室内側外向突部４２が第１溝部３５内に入り込むと共に、室外側外向突部４３が第２溝部３６に入り込む。
また、下框２１の本体４０には戸車４８が取付けてある。この戸車４８は下枠１１の室内側中間内向突部３２に設けたレール３２ａに接している。 By installing the shoji 2 in the frame 1, the outward projections of the upper collar 20 and the lower collar 21 overlap with the inward projections of the upper frame 10 and the lower frame 11, and the shoji 2 is closed. As a result, the outward protrusion of the door ridge 22 overlaps the inward protrusion of the vertical frame 12 in the direction of finding.
For example, the indoor-side outward protrusion 42 enters the first groove 35, and the outdoor-side outward protrusion 43 enters the second groove 36.
A door wheel 48 is attached to the main body 40 of the lower arm 21. The door wheel 48 is in contact with a rail 32 a provided on the indoor-side intermediate inward protrusion 32 of the lower frame 11.

このようであるから、框を熱溶着で連結して障子２の框体２４を形成できると共に、上枠１０、下枠１１、縦枠１２と上框２０、下框２１、戸当り框２２の見付け方向の重なり寸法を大きくできる。
また、召合せ框２３は、上框２０、下框２１、戸当り框２２における外向突部を備えていない本体４０のみで、その見付け寸法Ｈ_１は、本体４０と室内外側外向突部４２，４３を有した上框２０、下框２１、戸当り框２２の見付け寸法Ｈ_２よりも小さいから、内観の見栄えが良い。
また、召合せ框２３の見付け方向外端部は、本体４０の見付け方向外端面４０ａで、凹凸のない平坦面であるから、その見付け方向外端部に施錠部品、例えばクレセント３を取付けでき、従来のようにカバー材を取付ける必要がない。 As such, it is possible to form the casing 24 of the shoji 2 by connecting the scissors by heat welding, as well as the top frame 10, the bottom frame 11, the vertical frame 12 and the top scissors 20, the bottom scissors 21, and the door struts 22. The overlap dimension in the direction of finding can be increased.
Further,召合allowed stile 23, top rail 20, bottom rail 21, only the main body 40 having no outward protrusions in doorstop rail 22, the find dimensions _{H 1,} the body 40 and the chamber outer outward projection 42, 43 on rail 20 having a from bottom rail 21, less than find the dimension of H ₂ doorstop stile 22, the appearance of the introspection is good.
In addition, since the outer end portion in the finding direction of the summoning bowl 23 is the outer end surface 40a in the finding direction of the main body 40 and is a flat surface without unevenness, a locking part such as the crescent 3 can be attached to the outer end portion in the finding direction. There is no need to attach a cover material as in the past.

前記上框２０、下框２１、戸当り框２２は、その本体４０の室内側面４０ｄが外向突部、例えば室内側外向突部４２の室内側面４２ｂよりも室内寄りで、上框２０、下框２１、戸当り框２２は、本体４０の室内側部が外向突部（室内側外向突部４２）よりも室内側に張り出した形状である。
そして、上框２０、下框２１と召合せ框２３が、その召合せ框２３の本体４０の室内側面４０ｄと上框２０、下框２１の本体４０の室内側面４０ｄと室内外側方向に面一となるように連結してある。 The upper heel 20, the lower heel 21, and the door awning 22 have an indoor side surface 40d of the main body 40 that is closer to the interior than the indoor side surface 42b of the outward-facing protrusion, for example, the indoor-side outward protrusion 42. 21, the door-to-door ridge 22 has a shape in which the indoor side portion of the main body 40 protrudes to the indoor side from the outward projecting portion (the indoor outward projecting portion 42).
Then, the upper bowl 20, the lower bowl 21, and the summon bowl 23 are flush with the indoor side surface 40d of the main body 40 of the summit bowl 23 and the indoor side face 40d of the main body 40 of the lower bowl 21, and the indoor side direction. It is connected so that

このようであるから、上框２０、下框２１、戸当り框２２の本体４０と、召合せ框２３が同一見付け寸法で四周連続し、かつ上框２０、下框２１、戸当り框２２の本体４０の室内側部が外向突部よりも室内側に張り出した状態となるから、枠体１に障子２を建て込んだ状態で室内から見た時に、召合せ框２３と同一見付け寸法の上框２０、下框２１、戸当り框２２の本体４０における室内側張り出し部が四周連続して目立つから、内観が著しく見栄えが良い（図７参照）。 Because of this, the main body 40 of the upper cage 20, the lower cage 21, and the door cage 22 and the summon cage 23 are continuously connected with the same finding dimensions for four turns, and the upper cage 20, the lower cage 21, and the door cage 22 Since the indoor side portion of the main body 40 protrudes to the indoor side from the outward projection, the same size as that of the summoning bowl 23 is obtained when viewed from the room with the shoji 2 built in the frame 1. The interior overhanging portions of the main body 40 of the heel 20, the lower heel 21, and the door ridge 22 are conspicuous for four consecutive rounds, so that the inside appearance is remarkably good (see FIG. 7).

また、図１、図４に示すように障子２を閉じた状態で、戸当り框２２の本体４０の見付け方向外端面４０ａにおける室内側外向突部４２よりも室内側部分（つまり、室内側張り出し部）と、縦枠３０の室内側内向突部３１の内端面３１ｂとの間には隙間４がある。
例えば、図４に示すように、戸当り框２２の本体４０の見付け方向外端面４０ａに戸当り部材７０を取付け、障子２を閉じた状態で戸当り部材７０が縦枠１２の室内側寄り中間内向突部３２に当接すると共に、室内側外向突部４２が第１溝部３５に入り込むようにして前述の隙間４が生じるようにする。 As shown in FIGS. 1 and 4, with the shoji 2 closed, the indoor side portion (that is, the indoor side overhanging portion) of the indoor side outward projection 42 on the outer end surface 40a in the direction of finding the main body 40 of the door stopper 22 is shown. Part) and the inner end face 31b of the indoor-side inward projection 31 of the vertical frame 30 is a gap 4.
For example, as shown in FIG. 4, the door stop member 70 is attached to the outer end surface 40a of the main body 40 of the door stopper ridge 22, and the door stopper member 70 is located in the middle of the vertical frame 12 near the indoor side with the shoji 2 closed. While contacting the inward protrusion 32, the above-mentioned clearance 4 is formed so that the indoor outward protrusion 42 enters the first groove 35.

このようであるから、前述の隙間４に手の指を入れて戸当り框２２の本体４０に掛けて障子２を開き方向に移動できる。
つまり、戸当り框２２の本体４０における外向突部よりも室内側に張り出した部分を、障子２を開放する時の手掛けとすることができる。
したがって、障子２を人の手で開放操作し易い。 Thus, the shoji 2 can be moved in the opening direction by putting a finger in the gap 4 and hanging it on the main body 40 of the door ridge 22.
In other words, the portion of the main body 40 of the door-to-door fence 22 that protrudes to the indoor side from the outward projecting portion can be used as a handle when opening the shoji 2.
Therefore, it is easy to open the shoji 2 with human hands.

なお、前述の隙間４を手の指が入り込むことができない小さい隙間としても良い。
また、本体４０の室内側面４０ｄと外向突部の室内側面（室内側外向突部４２の室内側面４２ｂを面一、又は室内側面４２ｂが室内側に張り出すようにしても良い。 Note that the gap 4 described above may be a small gap that a finger of a hand cannot enter.
