Description

本発明は、対となるフランジに挟まれた開口を下向きにして建物開口部の上縁に取り付けたＣ型チャンネル構造のガイドレールに沿って折戸の移動側戸板を回転させながら案内する移動側戸板の移動ガイド部材に関する。   The present invention relates to a moving side door plate that guides while rotating a moving side door plate of a folding door along a guide rail of a C-type channel structure attached to the upper edge of a building opening with an opening sandwiched between a pair of flanges facing downward. This relates to a moving guide member.

本発明は、上下関係を逆にして、ガイドレールを建物開口部の下縁に取り付ける折戸や、ガイドレールを建物開口部の上縁及び下縁両方に取り付ける折戸にも実質同一に適用できるが、ガイドレールは建物開口部の上縁にのみ取り付けられる場合が多いため、ガイドレールを建物開口部の上縁に取り付けるものとして説明している。   The present invention can be applied substantially in the same manner to a folding door that attaches the guide rail to the lower edge of the building opening and the folding door that attaches the guide rail to both the upper edge and the lower edge of the building opening, with the vertical relationship reversed. Since the guide rail is often attached only to the upper edge of the building opening, the guide rail is described as being attached to the upper edge of the building opening.

対となるフランジに挟まれた開口を下向きにしてクローゼットや部屋の間仕切り等の建物開口部の上縁に取り付けたＣ型チャンネル構造のガイドレールに沿って折戸の移動側戸板を回転させながら案内する移動側戸板の移動ガイド部材は、輸送及び梱包効率を高めるため、一般的に施工現場で各移動側戸板に取り付ける。このため、移動ガイド部材を取り付けた移動側戸板を建物開口部に対して容易に取り付けること（以下、取付容易性）ができ、通常の開閉操作では移動側戸板が建物開口部から脱落しないように、移動ガイド部材がガイドレールのフランジに安定して係合していること（以下、取付安定性）が望まれる。しかし、取付容易性及び取付安定性は相反する要求になることから、両者の両立をどのように実現するかが問題となる。   Guiding by rotating the moving side door plate of the folding door along the guide rail of the C-type channel structure attached to the upper edge of the building opening such as a closet or room partition with the opening between the paired flanges facing downward In order to improve transportation and packing efficiency, the movement guide member of the movement side doorboard is generally attached to each movement side doorboard at the construction site. For this reason, it is possible to easily attach the moving side door plate to which the movement guide member is attached to the building opening (hereinafter, easy mounting) so that the moving side door plate does not fall out of the building opening in a normal opening / closing operation. It is desired that the moving guide member is stably engaged with the flange of the guide rail (hereinafter referred to as mounting stability). However, since ease of mounting and mounting stability are conflicting requirements, there is a problem of how to achieve both of them.

例えば特許文献１に見られる移動ガイド部材（戸板取付具）は、移動側戸板の上端面に旋回ピンを枢着する取付基礎ブロック（取付本体）と、ガイドレールの開口に下方から挿入する本体昇降部（凸部材）を、前記移動側戸板の裏面側で前記旋回ピンを軸に旋回させるガイド本体とから構成し、ガイドレールのフランジに係合させるガイド本体の本体昇降部を上方へ付勢して弾支している。これにより、ガイド本体の凸部（凸突起）を縮ませることでドライバー等の道具を要することなく、移動側戸板を建物開口部に対して容易に取り付けることができる。また、前記凸部の縮み代の範囲でガイドレールに対する凸部の挿入量が調整できることから、高さ調節を要することなく、ガイドレールのフランジに移動ガイド部材を安定して係合させることができる。このように、特許文献１の移動ガイド部材は、取付容易性及び取付安定性を両立させている。   For example, a moving guide member (door plate mounting tool) found in Patent Document 1 includes a mounting base block (mounting main body) that pivotally attaches a swivel pin to the upper end surface of the moving side door plate, and a main body lift that is inserted into the opening of the guide rail from below. And a guide body that pivots around the pivot pin on the back side of the moving side door plate, and urges the body lifting portion of the guide body engaged with the flange of the guide rail upward. I am supported. Thereby, a movement side doorboard can be easily attached with respect to a building opening part, without requiring tools, such as a driver, by shrinking the convex part (convex protrusion) of a guide main body. Further, since the insertion amount of the convex portion with respect to the guide rail can be adjusted within the range of the shrinkage allowance of the convex portion, the moving guide member can be stably engaged with the flange of the guide rail without requiring height adjustment. . As described above, the movement guide member of Patent Document 1 achieves both easy mounting and stable mounting.

特開2004-270380号公報（請求項１、［0020］〜［0021］）JP 2004-270380 A (Claim 1, [0020] to [0021])

しかし、特許文献１に見られる移動ガイド部材は、対となるフランジに挟まれた開口を有するＣ型チャンネル構造のガイドレールの前記開口に下方からガイド本体の凸部を挿入させ、ガイドレールのフランジに凸部を係合させていただけであったため、次のような問題があった。ガイドレールは、移動ガイド部材が位置する以外の広い範囲で開口が外部に開いており、新築時又は改築時の内装工事に伴う粉塵により前記開口から、前記ガイド本体の凸部とフランジとの間にゴミや埃が侵入し、溜まっていくことが少なくない。このゴミや埃は、ガイド本体の凸部に対する摺動抵抗となり、円滑な移動側戸板の開閉操作ができなくなってしまうことがあった。   However, the moving guide member found in Patent Document 1 has a guide rail convex portion inserted into the opening of the guide rail of the C-type channel structure having an opening sandwiched between a pair of flanges, and the guide rail flange. Since the convex part was merely engaged with the above, there were the following problems. The guide rail has an opening that opens to the outside in a wide range other than where the moving guide member is located. From the opening to the flange between the convex part of the guide body and the flange due to dust during interior construction during new construction or reconstruction. In many cases, dust and dirt enter and accumulate. This dust or dust becomes a sliding resistance against the convex part of the guide body, and it may be impossible to smoothly open and close the moving side door panel.

この点、特許文献１が開示される以前から見られる水平車輪を用いた移動ガイド部材であれば、前記水平車輪がガイドレール内を走行できる限り、移動側戸板の開閉操作を悪化させることが少ない。しかし、この水平車輪を用いた旧来の移動ガイド部材は、移動側戸板に大きな荷重が加わった際に水平車輪の車軸を破損させる虞があり、車軸の剛性を高めるために高価な材料を用いたり、大型化する必要があり、製造コストを増加させる問題がある。そこで、取付容易性及び取付安定性を両立させながら、移動側戸板の円滑な開閉操作を確保する水平車輪を備えた移動ガイド部材を安価に提供することを目的として、移動ガイド部材の構造を検討した。   If it is a movement guide member using the horizontal wheel seen before this point and patent document 1 are disclosed, as long as the said horizontal wheel can drive the inside of a guide rail, there will be few deterioration of the opening / closing operation of a movement side doorplate. . However, the conventional moving guide member using the horizontal wheel may damage the axle of the horizontal wheel when a large load is applied to the moving side door plate, and an expensive material may be used to increase the rigidity of the axle. Therefore, there is a problem that it is necessary to increase the size and increase the manufacturing cost. Therefore, the structure of the moving guide member is studied for the purpose of providing inexpensively a moving guide member with a horizontal wheel that ensures smooth opening and closing operation of the moving side door panel while achieving both easy mounting and mounting stability. did.

検討の結果、対となるフランジに挟まれた開口を下向きにして建物開口部の上縁に取り付けたＣ型チャンネル構造のガイドレールに沿って折戸の移動側戸板を回転させながら案内する移動側戸板の移動ガイド部材において、移動ガイド部材は、取り付けた移動側戸板に対して水平回動自在なガイド本体に、ガイドレールの開口に下方から挿入して、前記ガイドレールのフランジに常態として係合する水平車輪と、前記ガイドレールのフランジに常態として係合しない規制凸部とを設けた構成で、水平車輪は車軸をガイドレールのフランジ間隔等分線に一致させ、半径方向の最大変形量がΔRである弾性を備えたタイヤを取り付け、前記タイヤの外径をガイドレールのフランジ間隔に等しくし、規制凸部はガイドレールのフランジ間隔等分線を挟んだ対称形状で、前記規制凸部の幅を前記タイヤの外径より小さく、前記タイヤの外径からタイヤの最大変形量ΔRの２倍を差し引いた長さより大きくして、移動側戸板に荷重が加わるとタイヤを弾性変形させ、前記タイヤの変形量が最大変形量ΔRに達する前に規制凸部をガイドレールのフランジに係合させる移動側戸板の移動ガイド部材を開発した。   As a result of the study, the moving side door panel that guides while rotating the moving side door panel of the folding door along the C-type channel structure guide rail attached to the upper edge of the building opening with the opening sandwiched between the paired flanges facing downward In this moving guide member, the moving guide member is inserted into a guide body that is horizontally rotatable with respect to the attached moving side door plate from below into the opening of the guide rail, and is normally engaged with the flange of the guide rail. The horizontal wheel has a configuration in which a restriction convex portion that is not normally engaged with the flange of the guide rail is provided. The horizontal wheel has an axle aligned with the flange interval equipartition line of the guide rail, and the maximum deformation amount in the radial direction is ΔR. A tire having elasticity is attached, the outer diameter of the tire is made equal to the flange interval of the guide rail, and the regulating convex portion sandwiches the flange interval equipartition line of the guide rail. However, the width of the restricting convex portion is smaller than the outer diameter of the tire and larger than the length obtained by subtracting twice the maximum deformation amount ΔR of the tire from the outer diameter of the tire so that the load is applied to the moving side door plate. A moving guide member for a moving side door plate has been developed that, when applied, elastically deforms the tire and engages the restricting convex portion with the flange of the guide rail before the deformation amount of the tire reaches the maximum deformation amount ΔR.

ここで、「ガイドレールの開口に下方から挿入して、前記ガイドレールのフランジに」水平車輪又は規制凸部が係合する又は係合しないとは、開口からガイドレールの内部に挿入した水平車輪又は規制凸部が前記内部側から各フランジに水平方向から係合することを意味する。この場合、各フランジの縁部に補強用のリブを設けていれば、ガイドレールの開口は前記リブに挟まれた範囲となり、水平車輪又は規制凸部は前記リブに係合する。また、「タイヤの外径をガイドレールのフランジ間隔に等しく」するとは、水平車輪のがたつきを抑えるためにタイヤの外径をフランジの内側の間隔相当にすることを意味する。この場合、各フランジの縁部に補強用のリブを設けていれば、タイヤの外径はリブ間隔、すなわちリブの内側の間隔相当にする。現実には、水平車輪が回転する必要があることから、フランジ間隔又はリブ間隔に対し、タイヤの外径は0.1mm〜0.2mm程度小さくなる。そして、「フランジ間隔等分線」とは、対となるフランジの内側の間隔を等分するガイドレールの延在方向軸線を意味する。   Here, “inserted into the guide rail opening from below and engages with the flange of the guide rail” the horizontal wheel or the restricting convex part is engaged or not engaged means that the horizontal wheel inserted into the guide rail from the opening. Or it means that a control convex part engages with each flange from the inside from the horizontal direction. In this case, if a reinforcing rib is provided at the edge of each flange, the opening of the guide rail is in a range sandwiched between the ribs, and the horizontal wheel or the restricting convex portion engages with the rib. Further, “equal tire outer diameter equal to the guide rail flange spacing” means that the tire outer diameter is equivalent to the inner flange spacing in order to suppress rattling of the horizontal wheels. In this case, if reinforcing ribs are provided at the edge portions of the flanges, the outer diameter of the tire corresponds to the rib interval, that is, the interval inside the rib. In reality, since the horizontal wheel needs to rotate, the outer diameter of the tire is reduced by about 0.1 mm to 0.2 mm with respect to the flange interval or the rib interval. Further, the “flange interval equal line” means an extension direction axis line of the guide rail that equally divides the interval inside the paired flanges.

本発明の移動ガイド部材は、常態として水平車輪をガイドレールのフランジに係合させて移動側戸板を案内する。これにより、ガイドレールに侵入するゴミや埃の影響を受けることなく、移動側戸板の円滑な開閉操作を確保する。しかし、移動側戸板に荷重が加わると、水平車輪に取り付けたタイヤが弾性変形し、前記タイヤが最大変形量ΔRまで変形する前に規制凸部をガイドレールのフランジに係合させて車軸に負荷が加わらないようにし、水平車輪の破損を防止している。これら水平車輪と規制凸部とは、いずれもガイドレールの開口に下方から挿入するだけなので、取付容易性がある。そして、ガイド本体は、水平車輪及び規制凸部を一体にガイドレールに向けて付勢して弾性支持することにより、ガイドレールから水平車輪及び規制凸部が抜け出す虞をなくし、取付安定性を確保できる。ここで、移動ガイド部材は、移動側戸板に対する水平回動を、取付基礎ブロックとの軸着関係により実現しているので、水平車輪及び規制凸部を一体にガイドレールに向けて付勢して弾性支持する構造に特化できる。   The moving guide member of the present invention guides the moving side door plate by engaging the horizontal wheel with the flange of the guide rail as normal. Thereby, the smooth opening / closing operation of the moving side door plate is ensured without being affected by dust and dust entering the guide rail. However, if a load is applied to the moving side doorboard, the tire attached to the horizontal wheel is elastically deformed, and before the tire is deformed to the maximum deformation amount ΔR, the regulating protrusion is engaged with the flange of the guide rail and the axle is loaded. Prevents the horizontal wheels from being damaged. Since both the horizontal wheel and the restricting convex portion are only inserted from below into the opening of the guide rail, there is easy attachment. And the guide body urges the horizontal wheel and the restriction convex part integrally toward the guide rail to elastically support it, thereby eliminating the possibility of the horizontal wheel and the restriction convex part coming out from the guide rail and ensuring the mounting stability. it can. Here, since the moving guide member realizes horizontal rotation with respect to the moving side door plate by the axial attachment relationship with the mounting base block, the horizontal wheel and the regulating convex portion are urged integrally toward the guide rail. Specialize in elastically supported structures.

水平車輪及び規制凸部は、それぞれ少なくとも１基ずつガイド本体に設ければよいが、移動側戸板がこじれる場合を想定すれば、ガイド本体は、ガイドレールの延在方向の離れた位置関係にある２基一対の規制凸部と、前記規制凸部のガイドレールの延在方向外側に２基一対の水平車輪とを設けるとよい。ガイドレールの延在方向の離れた位置関係にある２基一対の規制凸部が、移動側戸板のこじれに対していずれかがガイドレールのフランジに係合するので、水平車輪を保護しやすい。この場合、ガイドレールがフランジの縁部にリブを有する構成であれば、前記リブに上方、すなわちガイドレールの内部から下方に向けて係合する脱落防止部材を規制凸部間に設けるとよい。また、ガイドレールの延在方向の離れた位置関係にある２基一対の規制凸部に対してガイドレールの延在方向外側に２基一対の水平車輪を設けることにより、水平車輪の間隔が拡がり、ガイドレールに対するガイド本体の直進安定性が向上する。   At least one horizontal wheel and one restricting convex portion may be provided on the guide body. However, assuming that the moving side door plate is distorted, the guide body is in a positional relationship in the extending direction of the guide rail. It is preferable to provide a pair of restriction convex portions and a pair of horizontal wheels on the outer side in the extending direction of the guide rails of the restriction convex portions. Since two of the pair of restricting convex portions in a positional relationship apart from each other in the extending direction of the guide rail engage with the flange of the guide rail with respect to the twisting of the moving side door plate, it is easy to protect the horizontal wheel. In this case, if the guide rail has a rib at the edge of the flange, a drop-off preventing member that engages the rib upward, that is, from the inside of the guide rail downward, may be provided between the restricting convex portions. Further, by providing two pairs of horizontal wheels on the outer side in the extending direction of the guide rail with respect to the two pairs of restricting convex portions in a positional relationship apart from each other in the extending direction of the guide rail, the distance between the horizontal wheels is widened. Further, the straight running stability of the guide body with respect to the guide rail is improved.

本発明は、水平車輪をガイド本体に支持する車輪取付部が弾性変形しても構わない。この場合、移動ガイド部材は、取り付けた移動側戸板に対して水平回動自在なガイド本体に、ガイドレールの開口に下方から挿入して、前記ガイドレールのフランジに常態として係合する水平車輪と、前記ガイドレールのフランジに常態として係合しない規制凸部とを設けた構成で、ガイドレールのフランジに向けた水平方向の最大変形量がΔRである弾性を備えた車輪取付部をガイド本体から突出し、水平車輪は前記車輪取付部に支持されており、水平車輪は車軸をガイドレールのフランジ間隔等分線に一致させ、前記水平車輪の外径をガイドレールのフランジ間隔に等しくし、規制凸部はガイドレールのフランジ間隔等分線を挟んだ対称形状で、前記規制凸部の幅を前記水平車輪の外径より小さく、前記水平車輪の外径から車輪取付部の最大変形量ΔRの２倍を差し引いた長さより大きくして、移動側戸板に荷重が加わると車輪取付部を弾性変形させ、前記車輪取付部の変形量が最大変形量ΔRに達する前に規制凸部をガイドレールのフランジに係合させる構成となる。   In the present invention, the wheel mounting portion that supports the horizontal wheel on the guide body may be elastically deformed. In this case, the moving guide member is inserted into a guide body that is horizontally rotatable with respect to the attached moving side door plate from below into the opening of the guide rail, and a horizontal wheel that is normally engaged with the flange of the guide rail. The wheel mounting portion having elasticity with a maximum horizontal deformation amount ΔR toward the flange of the guide rail from the guide main body is provided with a restriction convex portion that is not normally engaged with the flange of the guide rail. The horizontal wheel is supported by the wheel mounting portion, and the horizontal wheel has the axle aligned with the flange interval equator of the guide rail, the outer diameter of the horizontal wheel is equal to the flange interval of the guide rail, The part has a symmetrical shape with the guide rail flange interval equipartition line in between, and the width of the restricting convex part is smaller than the outer diameter of the horizontal wheel, and the outermost diameter of the horizontal wheel is changed from the outer diameter of the horizontal wheel. When the load is applied to the moving side door plate, the wheel mounting portion is elastically deformed by making the length larger than the length obtained by subtracting twice the deformation amount ΔR, and the restricting convex portion before the deformation amount of the wheel mounting portion reaches the maximum deformation amount ΔR. Is engaged with the flange of the guide rail.

この移動ガイド部材も、ガイド本体は、水平車輪及び規制凸部を一体にガイドレールに向けて付勢して弾性支持するとよい。また、ガイド本体は、幅狭状又は薄板状の可撓部を介して接続する車輪取付部を突出させ、前記車輪取付部は前記可撓部を弾性変形させる構成がよい。このほか、ガイド本体は、ガイドレールの延在方向の離れた位置関係にある２基一対の規制凸部と、前記規制凸部のガイドレールの延在方向外側に２基一対の水平車輪とを設ける構成が好ましい。この場合、ガイドレールがフランジ端にリブを有する構成であれば、前記リブの垂直方向に係合する脱落防止部材を規制凸部間に設けることが好ましい点も同様である。   In this moving guide member as well, the guide body may be elastically supported by urging the horizontal wheel and the restricting convex portion integrally toward the guide rail. Further, the guide main body preferably has a configuration in which a wheel mounting portion connected via a narrow or thin plate-like flexible portion protrudes, and the wheel mounting portion elastically deforms the flexible portion. In addition, the guide main body includes two pairs of restricting convex portions that are spaced apart from each other in the extending direction of the guide rail, and two pairs of horizontal wheels on the outside of the restricting convex portion in the extending direction of the guide rail. The structure to provide is preferable. In this case, if the guide rail has a rib at the flange end, a drop-off preventing member that engages in the vertical direction of the rib is preferably provided between the restricting convex portions.

本発明は、水平車輪による移動側戸板の円滑な開閉操作を実現しながら、移動側戸板に負荷が加わった場合でも、規制凸部が前記水平車輪の破損を防止できる。これは、水平車輪として安価な部材が利用できることを意味し、小型な移動ガイド部材を安価にする効果をもたらす。また、具体的な移動ガイド部材として、ガイドレールの延在方向の離れた位置関係にある２基一対の規制凸部と、前記規制凸部のガイドレールの延在方向外側に２基一対の水平車輪とを設ける構成にした場合、２基一対の規制凸部による確実な水平車輪の保護が図れ、離れた位置関係にある２基一対の水平車輪により、ガイドレールに対するガイド本体の直進安定性が向上するほか、ガイドレールのリブの垂直方向に係合する脱落防止部材を前記規制凸部間に追加し、移動ガイド部材の取付安定性を高める効果がある。   According to the present invention, even when a load is applied to the moving side door plate, the restriction convex portion can prevent the horizontal wheel from being damaged while realizing a smooth opening / closing operation of the moving side door plate by the horizontal wheel. This means that an inexpensive member can be used as the horizontal wheel, and the effect of reducing the cost of the small moving guide member is brought about. Further, as a specific moving guide member, two pairs of restricting convex portions in a positional relationship apart from each other in the extending direction of the guide rail, and two pairs of horizontal protrusions outside the restricting convex portion in the extending direction of the guide rail. When the structure is provided with the wheels, it is possible to reliably protect the horizontal wheels by the two pairs of restricting convex portions, and the two pairs of horizontal wheels in a distant positional relationship can improve the straight traveling stability of the guide body with respect to the guide rail. In addition to the improvement, a drop-off preventing member that engages in the vertical direction of the rib of the guide rail is added between the restricting convex portions, and there is an effect of improving the mounting stability of the moving guide member.

以下、本発明の実施形態について図を参照しながら説明する。図１は移動ガイド部材１を取り付けた移動側戸板61を用いたアウターセット形の折戸６の側面図、図２は折戸６を閉じた状態を表した平面図、図３は折戸６を開いた状態の上端面側を表した平面図、図４は折戸６を開いた状態の下端面側を表した平面図、図５は移動側戸板61に取り付けた移動ガイド部材１の側面図、図６は図５中Ａ−Ａ断面図、図７は移動ガイド部材１の分解斜視図、図８は移動ガイド部材１の移動側戸板61に対する取付関係を表した分解斜視図、図９はガイドレール８に移動ガイド部材１の本体昇降部21を挿入する直前の状態を表した断面図、図10はガイドレール８に移動ガイド部材１の本体昇降部21を挿入し終えた状態を表した断面図であり、そして図11は別例の移動ガイド部材１の移動側戸板61に対する取付関係を表した分解斜視図である。説明の便宜上、図１は破断線下が固定側戸板62，破断線上が移動側戸板61を表わしている。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a side view of an outer set type folding door 6 using a moving side door plate 61 to which a moving guide member 1 is attached, FIG. 2 is a plan view showing a state in which the folding door 6 is closed, and FIG. FIG. 4 is a plan view showing the lower end surface side in a state where the folding door 6 is opened, FIG. 5 is a side view of the moving guide member 1 attached to the moving side door plate 61, FIG. 5 is an AA cross-sectional view in FIG. 5, FIG. 7 is an exploded perspective view of the moving guide member 1, FIG. 8 is an exploded perspective view showing the mounting relationship of the moving guide member 1 to the moving side door plate 61, and FIG. FIG. 10 is a cross-sectional view showing a state immediately before the main body elevating part 21 of the moving guide member 1 is inserted into the guide rail 8, and FIG. And FIG. 11 is a diagram showing the mounting relationship of the moving guide member 1 of the other example to the moving side door plate 61. FIG. For convenience of explanation, FIG. 1 shows the fixed side door plate 62 below the broken line and the moving side door plate 61 above the broken line.

本例は、図１〜図４に見られるように、屈曲関係で連結した移動側戸板61及び固定側戸板62からなるアウターセット形の折戸６を建物開口部７に設けている。本例のガイドレール８は、対となるフランジ81,81に挟まれた開口82を下向きにして建物開口部７の上縁に取り付けられ、建物開口部７の下縁は床面71のままとしている。ガイドレールは、建物開口部７の上縁に取り付ける前記ガイドレール８に代えて又は前記ガイドレール８と共に、建物開口部７の下縁にも設けることができるが、本例のように、ガイドレール８を建物開口部７の上縁のみとし、床面71をそのままとすることにより、床面71に段差を設けずに済む利点が得られる。   In this example, as shown in FIGS. 1 to 4, an outer set type folding door 6 composed of a moving side door 61 and a fixed side door 62 connected in a bending relationship is provided in the building opening 7. The guide rail 8 of this example is attached to the upper edge of the building opening 7 with the opening 82 sandwiched between the pair of flanges 81, 81 facing downward, and the lower edge of the building opening 7 remains the floor surface 71. Yes. The guide rail can be provided on the lower edge of the building opening 7 instead of the guide rail 8 attached to the upper edge of the building opening 7 or together with the guide rail 8. By using 8 as the upper edge of the building opening 7 only and leaving the floor surface 71 as it is, an advantage of eliminating the need to provide a step on the floor surface 71 can be obtained.

固定側戸板62は、本発明の移動ガイド部材１から水平車輪５を除いた構成の旋回ガイド部材621を裏面側に取り付け、ガイドレール８に締着した固着補助具622により前記旋回ガイド部材621を拘束し、建物開口部７の側縁下端に固着した旋回受具623で軸支させて、旋回のみ可能にしている。固着補助具622は、旋回ガイド部材621を介して固定側戸板62、更には折戸６全体の傾倒を防止する役割を有している。本例の旋回ガイド部材621は、移動ガイド部材１から水平車輪５を除いた構成と同じなので、例えば旋回ガイド部材621に代えて移動ガイド部材１を位置固定で用いてもよい。   The fixed side door plate 62 is attached with a turning guide member 621 having a configuration in which the horizontal wheel 5 is removed from the moving guide member 1 of the present invention on the back side, and the turning guide member 621 is fixed by a fixing auxiliary tool 622 fastened to the guide rail 8. It is restrained and is pivotally supported by a swivel receiving tool 623 fixed to the lower end of the side edge of the building opening 7 so that only swiveling is possible. The fixing assisting tool 622 has a role of preventing the fixed-side door plate 62 and further the folding door 6 as a whole from being tilted via the turning guide member 621. Since the turning guide member 621 in this example is the same as the configuration in which the horizontal wheel 5 is removed from the moving guide member 1, the moving guide member 1 may be used in place of the turning guide member 621, for example.

移動側戸板61は、裏面側に移動ガイド部材１を取り付け、前記移動ガイド部材１が有する規制凸部４及び水平車輪５をガイドレール８の開口82に下方から挿入し、前記規制凸部４及び水平車輪５をガイドレール８に沿って移動させながら旋回可能にしている。すなわち、本例の折戸６は、旋回受具623が移動側戸板61及び固定側戸板62を一体に支持しながら、固定側戸板62を旋回ガイド部材621に従って旋回させ、移動側戸板61を移動ガイド部材１に従ってガイドレール８に案内させながら旋回させることにより、開閉する構成である。   The movement side door plate 61 has the movement guide member 1 attached to the back side, and the restriction convex part 4 and the horizontal wheel 5 of the movement guide member 1 are inserted into the opening 82 of the guide rail 8 from below, and the restriction convex part 4 and The horizontal wheel 5 can be turned while being moved along the guide rail 8. That is, in the folding door 6 of this example, while the turning support 623 integrally supports the moving side door plate 61 and the fixed side door plate 62, the fixed side door plate 62 is turned according to the turning guide member 621, and the moving side door plate 61 is moved. It is configured to open and close by turning while being guided by the guide rail 8 according to the member 1.

移動ガイド部材１は、図５〜図８に見られるように、移動側戸板61に取り付ける取付基礎ブロック３に対し、ガイドレール８の開口82に下方から挿入する水平車輪５及び規制凸部４を有するガイド本体２を水平旋回自在に軸着して構成される。具体的には、移動ガイド部材１は、ガイド本体２の旋回ピン28を取付基礎ブロック３に軸着することにより、取付基礎ブロック３に対してガイド本体２を旋回自在とする。このように、取付基礎ブロック３は移動側戸板61に対する移動ガイド部材１の水平旋回軸を形成する部分である。ガイドレール８の開口82に下方から水平車輪５及び規制凸部４を挿入するガイド本体２は前記ガイドレール８に対して向きが固定されていることから、取付基礎ブロック３を取り付けた移動側戸板61は、前記ガイド本体２に対して相対的に旋回する。   As shown in FIGS. 5 to 8, the moving guide member 1 has a horizontal wheel 5 and a restricting convex portion 4 inserted from below into the opening 82 of the guide rail 8 with respect to the mounting base block 3 attached to the moving side door 61. A guide main body 2 having a shaft is attached so as to be pivotable horizontally. Specifically, the movable guide member 1 pivots the guide pin 2 of the guide body 2 on the mounting base block 3 so that the guide body 2 can turn with respect to the mounting base block 3. As described above, the mounting base block 3 is a portion that forms the horizontal turning axis of the moving guide member 1 with respect to the moving side door plate 61. Since the guide body 2 for inserting the horizontal wheel 5 and the restricting convex portion 4 from below into the opening 82 of the guide rail 8 is fixed with respect to the guide rail 8, the moving side door plate to which the mounting base block 3 is attached. 61 pivots relative to the guide body 2.

取付基礎ブロック３は、旋回ピン28が貫通する深さの旋回軸孔31を穿孔した樹脂製ブロック体からなり、移動側戸板61の上端面角部に嵌合する。この取付基礎ブロック３には、ガイド本体２の本体受け部22から水平に折り曲げた旋回板27から垂下した旋回ピン28を軸着する。旋回ピン28は、取付基礎ブロック３に穿孔した旋回軸孔31より深い位置（正確には旋回軸孔31及び抜止板32の厚みの合計より深い位置）に貫通させた係止ピン281の両端を半径方向に突出させている。移動ガイド部材１は、移動側戸板61の上端面角部に嵌合した取付基礎ブロック３に対し、旋回板27及びガイド本体２が一体に旋回する。   The mounting base block 3 is made of a resin block body having a turning shaft hole 31 having a depth through which the turning pin 28 penetrates, and is fitted to an upper end surface corner of the moving side door plate 61. A pivot pin 28 hanging from a pivot plate 27 bent horizontally from the main body receiving portion 22 of the guide main body 2 is pivotally attached to the mounting base block 3. The pivot pin 28 has both ends of a locking pin 281 penetrating into a position deeper than the pivot shaft hole 31 drilled in the mounting base block 3 (more precisely, a position deeper than the total thickness of the pivot shaft hole 31 and the retaining plate 32). It protrudes in the radial direction. In the moving guide member 1, the turning plate 27 and the guide main body 2 turn integrally with respect to the mounting base block 3 fitted to the upper end surface corner of the moving side door plate 61.

本例の取付基礎ブロック３は、未だ中空状態にある移動側戸板61の上端面角部に嵌合させた後、前記移動側戸板61内にウレタン樹脂を注入発泡させることにより、前記移動側戸板61と接着一体化する。また、本例の取付基礎ブロック３は、移動側戸板61を構成する鋼鈑が形成する突き合わせフランジに設けた切欠611を、前記突き合わせフランジを差し込む取付基礎ブロック３の差し込み溝33に係合突起331をそれぞれ設け、前記切欠611に前記係合突起331を係合させて、移動側戸板61の上端面から取付基礎ブロック３が抜け出すことを防止している。このほか、図示は省略するが、移動側戸板61の上端面を塞ぐ型材612（図８参照）に突片を設け、前記突片により取付基礎ブロック３を押さえ込ませると、取付基礎ブロック３の抜け止めがより確実になる。   The mounting base block 3 of this example is fitted to the upper end surface corner of the moving side door plate 61 that is still hollow, and then injected and foamed urethane resin into the moving side door plate 61, thereby moving the moving side door plate. Bonded and integrated with 61. Further, in the mounting base block 3 of this example, the notch 611 provided in the butt flange formed by the steel plate constituting the moving side door plate 61 is engaged with the insertion protrusion 33 of the mounting base block 3 into which the butt flange is inserted. And the engaging protrusion 331 is engaged with the notch 611 to prevent the mounting base block 3 from coming out of the upper end surface of the moving side door plate 61. In addition, although illustration is omitted, if a projecting piece is provided on a mold material 612 (see FIG. 8) that closes the upper end surface of the moving side door plate 61 and the mounting base block 3 is pressed by the projecting piece, the mounting base block 3 is removed. The stop is more reliable.

取付基礎ブロック３に穿孔した旋回軸孔31は、半径方向に凹んだ一対のキー溝311,311を刻設し、旋回軸孔31及びキー溝311を合わせた断面形状に等しい挿通孔321を設けた金属製の抜止板32を下端に嵌め込んでいる。抜止板32は、キー溝311を通じて差し込まれる旋回ピン28の係止ピン281を係合させて、前記旋回ピン28の抜け止めを図る。この抜止板32は、係合する旋回ピン28の係止ピン281との擦れ合いによる磨耗や、旋回ピン28に引き抜き荷重が掛かった際の係止ピン281による破損がないため、係止ピン281を安定して係合させておくことができる。移動ガイド部材１は、旋回軸孔31に旋回ピン28を抜止状態で差し込むだけで、移動側戸板61の上端面に取り付けることができる。   The pivot shaft hole 31 drilled in the mounting base block 3 has a pair of key grooves 311 and 311 that are recessed in the radial direction, and a metal provided with an insertion hole 321 having the same cross-sectional shape of the pivot shaft hole 31 and the key groove 311 combined. A retaining plate 32 made of metal is fitted into the lower end. The retaining plate 32 engages the locking pin 281 of the pivot pin 28 inserted through the key groove 311 to prevent the pivot pin 28 from coming off. The retaining plate 32 is not worn due to friction between the engaging pivot pin 28 and the retaining pin 281 and is not damaged by the retaining pin 281 when a pulling load is applied to the pivot pin 28. Can be stably engaged. The moving guide member 1 can be attached to the upper end surface of the moving side door 61 simply by inserting the swivel pin 28 into the swivel shaft hole 31 in a state of being removed.

ここで、移動側戸板61を建物開口部７に取り付ける前は、旋回ピン28を旋回軸孔31に抜き差し自在としながら、移動側戸板61を建物開口部７に取り付けた後は、旋回ピン28を旋回軸孔31に対して抜止状態にある必要がある。本例は、旋回軸孔31に刻設したキー溝311と旋回ピン28から突出する係止ピン281との水平面内における位置関係を特定している。すなわち、本例のキー溝311と係止ピン281とは、ガイド本体２と移動側戸板61との開度が135度になる位置関係で一致させて、旋回ピン28を旋回軸孔31に差し込み、移動側戸板61の開閉操作に従う旋回ピン28の通常旋回範囲でキー溝311と係止ピン281とが一致しないようにすることで、抜け止めを図っている。本例は、移動側戸板61が約90度の開度を有するように、前記旋回ピン28の通常旋回範囲を０度〜90度としている。   Here, before attaching the moving side door panel 61 to the building opening 7, before attaching the moving side door board 61 to the building opening 7, while attaching the moving side door board 61 to the building opening 7, the turning pin 28 can be freely inserted into and removed from the turning shaft hole 31. The pivot shaft hole 31 needs to be in a removal state. In this example, the positional relationship in the horizontal plane between the key groove 311 engraved in the turning shaft hole 31 and the locking pin 281 protruding from the turning pin 28 is specified. That is, the key groove 311 and the locking pin 281 of this example are aligned with each other so that the opening degree of the guide body 2 and the moving side door plate 61 is 135 degrees, and the turning pin 28 is inserted into the turning shaft hole 31. The key groove 311 and the locking pin 281 do not coincide with each other in the normal turning range of the turning pin 28 according to the opening / closing operation of the moving side door plate 61, thereby preventing the removal. In this example, the normal turning range of the turning pin 28 is set to 0 degree to 90 degrees so that the moving side door plate 61 has an opening of about 90 degrees.

ガイド本体２は、上記旋回板27を一体に設けた金属製外形箱型の本体受け部22と、この本体受け部22へ昇降自在に収納した樹脂ブロックの本体昇降部21とから構成される（図６参照）。本体受け部22は、コイルスプリング23を係止する支持突起221を底面から切り起こし、本体昇降部21の昇降方向を規制する平行レール223,223と、本体昇降部21の逸脱を防止する拘束ピン24の差込孔222とを、それぞれ側面に一体成形している。   The guide main body 2 is composed of a metal outer box-shaped main body receiving portion 22 integrally provided with the swivel plate 27 and a resin block main body elevating portion 21 which is housed in the main body receiving portion 22 so as to be movable up and down ( (See FIG. 6). The main body receiving portion 22 cuts and raises the support protrusion 221 that locks the coil spring 23 from the bottom surface, and includes parallel rails 223 and 223 that regulate the raising and lowering direction of the main body raising and lowering portion 21 and a restraining pin 24 that prevents the main body raising and lowering portion 21 from deviating. The insertion holes 222 are integrally formed on the side surfaces.

本体昇降部21は、本体受け部22の支持突起221に下端を係止させたコイルスプリング23を遊嵌させるスプリング孔26を底面から上方に向けて穿孔し、本体受け部22の平行レール223,223に規制されるレール溝213を側面に、本体受け部22の側面縁部に被せるガイドフランジ211,211を側面縁部にそれぞれ設け（図６参照）、本体受け部22の差込孔222から拘束ピン24を挿通させる上下方向の長孔からなる拘束溝212を側面間にわたって貫設している。この本体昇降部21は、前記コイルスプリング23により上向きに付勢された状態で弾支されている。前記弾支による本体昇降部21の昇降方向は、本体受け部22の平行レール223にレール溝213を係合させて規制され、本体昇降部21の昇降範囲は本体受け部22から差し込んだ拘束ピン24を拘束溝212に挿通させて規制されている。   The main body elevating part 21 pierces a spring hole 26 for loosely fitting a coil spring 23 whose lower end is engaged with the support protrusion 221 of the main body receiving part 22 upward from the bottom surface. Guide flanges 211 and 211 are provided on the side edges of the rail groove 213 to be regulated and on the side edges of the body receiving portion 22 (see FIG. 6), and the restraining pin 24 is inserted from the insertion hole 222 of the body receiving portion 22. A constraining groove 212 made of a long hole in the vertical direction is inserted through the side surfaces. The main body elevating part 21 is elastically supported while being biased upward by the coil spring 23. The ascending / descending direction of the main body elevating part 21 by the elastic support is regulated by engaging the rail groove 213 with the parallel rail 223 of the main body receiving part 22, and the elevating range of the main body elevating part 21 is a restraining pin inserted from the main body receiving part 22 24 is inserted into the restraining groove 212 to be regulated.

本発明の特徴である規制凸部４,４及び水平車輪５,５は、本体昇降部21の上面に、それぞれガイドレール８の延在方向の離れた位置関係で２基一対設けられている。具体的には、２基一対の規制凸部４,４が本体昇降部21の上面から上向きに突設され、２基一対の水平車輪５,５は前記各規制凸部４のガイドレールの延在方向外側へ水平に張り出した車輪取付部51,51に軸着されている。これから、規制凸部４,４及び水平車輪５,５は、本体昇降部21と一体に本体受け部22に対して弾支されていることになる。車輪取付部51は規制凸部４と一体の樹脂製であり、金属製の車軸512を有する。水平車輪５は、前記車軸512に樹脂製のホイール52を軸着し、前記ホイール52にゴム製のタイヤ53を嵌めて構成される。   The control convex portions 4, 4 and the horizontal wheels 5, 5, which are the features of the present invention, are provided in pairs on the upper surface of the main body lifting / lowering portion 21 in a positional relationship apart from each other in the extending direction of the guide rail 8. Specifically, two pairs of restricting convex portions 4, 4 project upward from the upper surface of the main body lifting / lowering portion 21, and two pairs of horizontal wheels 5, 5 extend the guide rails of the restricting convex portions 4. It is pivotally attached to the wheel mounting portions 51 and 51 that project horizontally outward in the present direction. From this, the regulation convex parts 4 and 4 and the horizontal wheels 5 and 5 are elastically supported with respect to the main body receiving part 22 integrally with the main body raising / lowering part 21. The wheel mounting portion 51 is made of a resin integral with the restricting convex portion 4 and has a metal axle 512. The horizontal wheel 5 is configured by attaching a resin wheel 52 to the axle 512 and fitting a rubber tire 53 on the wheel 52.

本例は、車輪取付部51が幅狭状かつ薄板状の可撓部511を介して規制凸部４から張り出している。移動側戸板61に負荷が加わった場合、前記車輪取付部51が可撓部511により水平方向に弾性変形して、水平車輪５に加わる力をガイドレール８のリブ83から逃がし、代わって規制凸部４をガイドレール８のリブ83に係合させて、水平車輪５の破損を防止する。このため、本例は水平車輪５の車軸512をガイドレール８のフランジ間隔等分線Ｌに一致させると共に、規制凸部４を前記フランジ間隔等分線Ｌを挟んだ対称な直方体形状にし、可撓部511による車輪取付部51の水平方向の最大変形量をΔR（図３中一方向（図面上側）の最大変形量ΔＲのみ図示）とし、規制凸部４の幅を水平車輪５の外径より小さく、前記水平車輪５の外径から車輪取付部51の最大変形量ΔRの２倍を差し引いた長さより大きくして、車輪取付部51の変形量が最大変形量ΔRに達する前に規制凸部４をガイドレール８のフランジ81の縁部に設けたリブ83に係合させる。   In this example, the wheel mounting portion 51 protrudes from the restricting convex portion 4 via a flexible portion 511 having a narrow and thin plate shape. When a load is applied to the moving side door plate 61, the wheel mounting portion 51 is elastically deformed in the horizontal direction by the flexible portion 511, so that the force applied to the horizontal wheel 5 is released from the rib 83 of the guide rail 8, and is instead regulated. The part 4 is engaged with the rib 83 of the guide rail 8 to prevent the horizontal wheel 5 from being damaged. For this reason, in this example, the axle 512 of the horizontal wheel 5 is made to coincide with the flange interval equal line L of the guide rail 8, and the regulating convex part 4 is formed in a symmetrical rectangular parallelepiped shape with the flange interval equal line L in between. The maximum horizontal deformation amount of the wheel mounting portion 51 by the flexible portion 511 is ΔR (only the maximum deformation amount ΔR in one direction (upper side of the drawing) in FIG. 3 is shown), and the width of the restricting convex portion 4 is the outer diameter of the horizontal wheel 5. It is smaller than the outer diameter of the horizontal wheel 5 and the length obtained by subtracting twice the maximum deformation amount ΔR of the wheel mounting portion 51, so that the deformation amount of the wheel mounting portion 51 reaches the maximum deformation amount ΔR. The portion 4 is engaged with a rib 83 provided at the edge of the flange 81 of the guide rail 8.

本例は、車輪取付部51が弾性変形するため、水平車輪５のタイヤ53に弾性は要求されない。しかし、例えば可撓部を設けていない又は可撓部による弾性が十分でない場合、水平車輪５は半径方向の最大変形量がΔRである弾性を備えたタイヤ53をホイール52に嵌める構成とし、上述同様、水平車輪５の車軸512をガイドレール８のフランジ間隔等分線Ｌに一致させ、規制凸部４の幅を前記タイヤ53の外径より小さく、前記タイヤ53の外径からタイヤ53の最大変形量ΔRの２倍を差し引いた長さより大きくすれば、タイヤ53の変形量が最大変形量ΔRに達する前に規制凸部４をガイドレール８のフランジ81の縁部に設けたリブ83に係合させることができる。本発明は、車輪取付部51又は水平車輪５のタイヤ53のいずれかを弾性変形させればよいため、本例の構成又は前記タイヤ53による構成のいずれかを用いればよいが、両者を組み合せて用いれば、ガイドレール８のフランジ81の縁部に設けたリブ83に対する規制凸部４の係合がより確実となる。   In this example, since the wheel mounting portion 51 is elastically deformed, the tire 53 of the horizontal wheel 5 is not required to be elastic. However, for example, when the flexible portion is not provided or the elasticity by the flexible portion is not sufficient, the horizontal wheel 5 is configured to fit the tire 53 having elasticity with the maximum amount of deformation in the radial direction to the wheel 52, as described above. Similarly, the axle 512 of the horizontal wheel 5 is made to coincide with the flange interval equipartition line L of the guide rail 8, the width of the restricting convex portion 4 is smaller than the outer diameter of the tire 53, and the maximum diameter of the tire 53 is increased from the outer diameter of the tire 53. If the length is larger than the length obtained by subtracting twice the deformation amount ΔR, the restricting convex portion 4 is engaged with the rib 83 provided on the edge of the flange 81 of the guide rail 8 before the deformation amount of the tire 53 reaches the maximum deformation amount ΔR. Can be combined. In the present invention, since either the wheel mounting portion 51 or the tire 53 of the horizontal wheel 5 may be elastically deformed, either the configuration of the present example or the configuration of the tire 53 may be used. If it uses, the engagement of the control convex part 4 with the rib 83 provided in the edge part of the flange 81 of the guide rail 8 will become more reliable.

このほか、本例の移動ガイド部材１は、前記規制凸部４,４の間に、ガイドレール８の内部から下方に向けてリブ83に係合する脱落防止部材25を配している。脱落防止部材25は、移動片251及び係合片252からなる断面上下反転Ｌ字状金属片である。この脱落防止部材25は、移動片251を規制凸部４,４間から本体昇降部21内に差し込み、係合片252を規制凸部４,４間から水平に突出させている。移動片251は、本体昇降部21を貫通させた付勢ピン253を螺合により一体化させているので、この付勢ピン253を付勢に抗して押し込むことにより、ガイドレール８のフランジ81から係合片252を遠ざけることができる。   In addition, the moving guide member 1 of the present example is provided with a drop-off preventing member 25 that engages with the rib 83 downward from the inside of the guide rail 8 between the restricting convex portions 4 and 4. The drop-off prevention member 25 is an L-shaped metal piece that is vertically inverted in cross section and includes a moving piece 251 and an engaging piece 252. The drop-off preventing member 25 has a movable piece 251 inserted into the main body elevating part 21 from between the restricting convex parts 4 and 4 and an engaging piece 252 protruding horizontally from between the restricting convex parts 4 and 4. Since the movable piece 251 has a biasing pin 253 penetrating the main body elevating part 21 integrated by screwing, the flange 81 of the guide rail 8 is pushed by pushing the biasing pin 253 against the biasing. The engagement piece 252 can be moved away from the first position.

移動ガイド部材１を取り付けた移動側戸板61は、固定側戸板62に対して折り畳んだ状態とし、前記固定側戸板62と共に建物開口部７下縁（本例では床面71）に傾けて置いた状態から引き起こし、固定側戸板62の下端面を旋回受具623に軸支させてから、ガイド本体２をガイドレール８直下へ持ってくる。ここで、コイルスプリング23により本体昇降部21は弾支されているので、このままでは規制凸部４,４及び水平車輪５,５がガイドレール８の側面に当たり、規制凸部４,４及び水平車輪５,５をガイドレール８の開口82に下方から挿入できない。そこで、図９に見られるように、本体昇降部21を作業者の手によって押し下げて規制凸部４,４及び水平車輪５,５をガイドレール８直下に持っていき、図10に見られるように、本体昇降部21の押し下げをやめると、本体昇降部21が上昇して規制凸部４,４及び水平車輪５,５をガイドレール８の開口82に下方から挿入できる。   The moving side door plate 61 to which the moving guide member 1 is attached is folded with respect to the fixed side door plate 62 and is tilted with the fixed side door plate 62 at the lower edge of the building opening 7 (in this example, the floor surface 71). From the state, the lower end surface of the fixed side door plate 62 is pivotally supported by the swivel support 623, and then the guide body 2 is brought directly below the guide rail 8. Here, since the main body elevating part 21 is elastically supported by the coil spring 23, the restricting convex parts 4, 4 and the horizontal wheels 5, 5 hit the side surface of the guide rail 8 in this state, and the restricting convex parts 4, 4 and the horizontal wheel 5 and 5 cannot be inserted into the opening 82 of the guide rail 8 from below. Therefore, as shown in FIG. 9, the main body elevating part 21 is pushed down by the operator's hand and the restricting convex parts 4, 4 and the horizontal wheels 5, 5 are brought directly under the guide rail 8, and as shown in FIG. When the lowering of the main body elevating part 21 is stopped, the main body elevating part 21 rises and the restricting convex parts 4, 4 and the horizontal wheels 5, 5 can be inserted into the opening 82 of the guide rail 8 from below.

本体昇降部21は、規制凸部４を除く上面をガイドレール８のフランジ81の縁部に設けたリブ83に下方から当接させることにより、規制凸部４及び水平車輪５のガイドレール８に対する挿入量を制限する。これにより、リブ83の高さ方向の厚みが薄くても、前記リブ83に対して水平車輪５を確実にガイドレール８に係合させることができる。そして、水平車輪５より規制凸部４を高さ方向に突出させておくと規制凸部４も確実にガイドレール８の開口82に下方から挿入でき、車輪取付部51を弾性変形させた際、規制凸部４をガイドレール８のフランジ81の縁部に設けたリブ83に係合させることができる。   The main body elevating part 21 makes the upper surface excluding the restricting convex part 4 abut against the rib 83 provided at the edge of the flange 81 of the guide rail 8 from below, thereby restricting the restricting convex part 4 and the horizontal wheel 5 with respect to the guide rail 8. Limit the amount of insertion. Thereby, even if the thickness of the rib 83 in the height direction is thin, the horizontal wheel 5 can be reliably engaged with the guide rail 8 with respect to the rib 83. And if the control convex part 4 is protruded in the height direction from the horizontal wheel 5, the control convex part 4 can also be reliably inserted into the opening 82 of the guide rail 8 from below, and when the wheel mounting part 51 is elastically deformed, The restricting convex portion 4 can be engaged with a rib 83 provided at the edge of the flange 81 of the guide rail 8.

本体昇降部21の規制凸部４及び水平車輪５をガイドレール８に挿入できれば、建物開口部７に対する移動側戸板61及び固定側戸板62の取付が完了する。本例は、移動側戸板61及び固定側戸板62の取付安定性を確保するため、ガイドレール８に挿入した規制凸部４,４の間に脱落防止部材25を設けている。本例の脱落防止部材25は、圧縮バネによりガイドレール８のフランジ81に向けて付勢されて本体昇降部21の前面から突出する付勢ピン253を移動片251に固着している。脱落防止部材25の係合片252は、上面が前記付勢ピン253の付勢方向に下り勾配で傾斜しているため、規制凸部４及び水平車輪５をガイドレール８の開口82に下方から挿入する際、ガイドレール８のフランジ81の縁部に設けたリブ83に押されて逃げながら、ガイドレール８の内部に差し込むことができる。そして、前記リブ83を通過した係合片252は、付勢ピン253の付勢によりガイドレール８のフランジ81に向けて移動する移動片251に従って、前記フランジ81に向けて移動し、リブ83に上方から係合する（図10中右方向）。こうして、脱落防止部材25をガイドレール８のフランジ81の縁部に設けたリブ83に係合させた移動側戸板61は、通常の開閉操作に際してガイドレール８から外れる虞がなくなる。この係合片252は、付勢に抗して付勢ピン253を押し込む（図９参照）ことにより、容易にリブ83との係合を解除できる。   If the restriction convex part 4 and the horizontal wheel 5 of the main body elevating part 21 can be inserted into the guide rail 8, the mounting of the moving side door 61 and the fixed side door 62 to the building opening 7 is completed. In this example, in order to secure the mounting stability of the moving side door plate 61 and the fixed side door plate 62, a drop-off prevention member 25 is provided between the restricting convex portions 4, 4 inserted into the guide rail 8. The drop-off prevention member 25 of this example is fixed to the moving piece 251 with a biasing pin 253 that is biased toward the flange 81 of the guide rail 8 by a compression spring and protrudes from the front surface of the main body lifting / lowering portion 21. Since the upper surface of the engagement piece 252 of the drop-off prevention member 25 is inclined downward in the urging direction of the urging pin 253, the restricting convex portion 4 and the horizontal wheel 5 are inserted into the opening 82 of the guide rail 8 from below. When inserting, the guide rail 8 can be inserted into the guide rail 8 while being pushed away by the rib 83 provided at the edge of the flange 81 of the guide rail 8. Then, the engagement piece 252 that has passed through the rib 83 moves toward the flange 81 according to the moving piece 251 that moves toward the flange 81 of the guide rail 8 by the urging force of the urging pin 253, Engage from above (right direction in FIG. 10). In this way, there is no possibility that the moving side door panel 61 in which the drop-off preventing member 25 is engaged with the rib 83 provided at the edge of the flange 81 of the guide rail 8 is detached from the guide rail 8 during a normal opening / closing operation. The engagement piece 252 can be easily disengaged from the rib 83 by pushing the urging pin 253 against the urging (see FIG. 9).

本発明の移動ガイド部材１は、移動側戸板61の上端面又は下端面（ガイドレール８を建物開口部７の下縁に取り付けた場合）に枢着できればよく、移動側戸板61の上端面又は下端面に嵌合する取付基礎ブロックは必須ではない。例えば、図11に見られるように、木製中実の移動側戸板61に木ネジ291を用いて固着した取付補助具29に対し、留めネジ292によりガイド本体２を枢着しても構わない。この結果、ネジ止め等を不要にして取付作業を容易にする上述の例（図１以下参照）の利点は失われるが、移動側戸板61に取付基礎ブロック３を嵌合させる加工が不要になる利点を新たに得ることができる。また、前記取付補助具29を用いることにより、移動側戸板61に直接軸孔を穿設しなくてよくなる利点も得られる。   The movement guide member 1 of the present invention only needs to be pivotally attached to the upper end surface or lower end surface of the moving side door plate 61 (when the guide rail 8 is attached to the lower edge of the building opening 7). A mounting base block fitted to the lower end surface is not essential. For example, as shown in FIG. 11, the guide body 2 may be pivotally attached to the attachment assisting tool 29 secured to the wooden solid moving side door plate 61 using a wood screw 291 with a retaining screw 292. As a result, the advantage of the above-described example (refer to FIG. 1 and subsequent drawings) that facilitates the mounting operation by eliminating screwing or the like is lost, but the processing for fitting the mounting base block 3 to the moving side door plate 61 is not required. New benefits can be obtained. Further, the use of the attachment assisting tool 29 also provides an advantage that it is not necessary to directly drill the shaft hole in the moving side door plate 61.
