【発明の属する技術分野】
本発明は、引戸を立て付ける鴨居に取り付けられるレールと、引戸の頂面に取り付けられ且つ前記レールと嵌合して引戸の円滑な開閉が行われるように構成したスライダーとの組み合わせからなる引戸の上方部分におけるガイド装置に関するものである。
【０００２】
【従来の技術】
周知の如く従来の引戸の上方部分は、頂面に突出形成された凸部が鴨居の下端面に形成された溝に嵌合しており、引戸の開閉時に前記凸部が鴨居の溝部を摺動することによってガイドされている。
【０００３】
【発明が解決しようとする課題】
ところが、引戸の頂面の凸部と鴨居の溝部との接触面積は広く、そのため引戸の開閉に際して抵抗が大きく円滑な開閉が行われない場合が生じるなどの問題がある。
【０００４】
また一般に、円滑な開閉が行われるように、引戸の底面に戸車を装着させるのが一般的であり、殊に引戸の厚さ方向に車の位置を調整可能とすることにより良好な立付けを簡単に行うことのできる戸車が用いられている。
【０００５】
しかしながら、引戸の底面に取り付けた戸車の位置を厚さ方向に調整可能であっても、上方における厚さ方向の調節ができないため、下端だけを厚さ方向の位置に調節すると、引戸全体が傾き、円滑な開閉が行われないという問題もある。
【０００６】
【課題を解決するための手段】
前記課題を解決するため、本発明の引戸のガイド装置として、下端に細長円柱状のガイド部を備えたほぼ断面逆鍵孔形状又はほぼ断面T字形状を有して鴨居に取付け、固定されるレールと、固定状態にある前記レールの上記ガイド部を摺接状態に嵌合させる溝状の嵌挿部を頂面に設けて引戸自体の頂面に取り付けられ、引戸の走行時に上記レールを案内にして摺動可能に設けられるスライダーとを具備し、かつ上記スライダーは、上記溝状の嵌挿部を有した嵌挿部材と、該嵌挿部材を引戸走行方向に平行な二つの側壁間に内包すると共に上記二つの側壁に上記引戸走行方向と直交した幅方向に延設される支持杆に沿って幅方向に該嵌挿部材を位置ずれ可能に把持するスライダー本体部材と、上記スライダー本体部材の上記二つの側壁と交差した一方の端壁に装着した上記嵌挿部材を幅方向に調整可能に位置決め操作する操作手段とを具備したことを特徴とする。
【０００７】
また、前記課題の解決手段として、本発明の引戸のガイド装置は、それぞれ下端に細長円柱状のガイド部を備えたほぼ断面下向きコ字形状を有して鴨居に取付け、固定されるレールと、固定状態にある前記レールの前記ガイド部を摺接状態に嵌合させる溝状の嵌挿部を頂面に設けて引戸自体の頂面に取り付けられ、引戸の走行時に前記レールを案内にして摺動可能に設けられるスライダーとを具備し、かつ前記スライダーは、前記溝状の嵌挿部を有した嵌挿部材と、該嵌挿部材を引戸走行方向に平行な二つの側壁間に内包すると共に前記二つの側壁に前記引戸走行方向と直交した幅方向に延設される支持杆に沿って幅方向に該嵌挿部材を位置ずれ可能に把持するスライダー本体部材と、前記スライダー本体部材の前記二つの側壁と交差した一方の端壁に装着した前記嵌挿部材を幅方向に調整可能に位置決め操作する操作手段とを具備したことを特徴とする。
【０００８】
【発明の実施の形態】
次に、本発明の実施の形態を図面に就いて説明する。
【０００９】
図１および図２は本発明の好ましい実施の形態の一つを示すものであり、鴨居１の下端面２に取り付けられるレール３と、引戸６の頂面７に沿って取り付けられるスライダー８とから構成される。
【００１０】
レール３は鴨居１の幅方向に延びて鴨居１の下端面２に取り付けられる取付片９と、この取付片９の一端から下方に延びる脚片１０とによって、端面Ｌ字形に構成され、脚片１０は下端に脚片１０の幅方向に膨出形成された細長円筒状のガイド部１１が備えられて断面が逆鍵孔状に形成されている。
【００１１】
そして、レール３は取付片９を適宜の固定ねじを用いて鴨居１の下端面２に沿って取り付けられる。
【００１２】
一方、スライダー８は全体が函形形状をなし、その頂面４の中央に前記レール３のガイド部１１を摺動可能に嵌合させる溝状の嵌挿部５が長手方向に亘って形成されている。
【００１３】
スライダー８は、例えば図１に示すように、引戸６の頂面７と走行方向に直交する木口面１５との角部１２に形成した嵌合凹部１３に頂面４を引戸６の頂面７と面一にして、且つスライダー８の一方の側面１４を引戸６の木口面１５と面一にして配置され、スライダー８の底部において固定ねじ１７をもって取り付ける。
【００１４】
そして、引戸６はその頂面７に位置するスライダー８の嵌挿凹部５にレール３のガイド部１１を嵌合させて立て付けるものである。
【００１５】
以上のように構成した本実施の形態は、略細長円筒状のガイド部１１の両側が嵌挿凹部５の両端面１６，１６にガイドされて安定した状態で走行し、且つガイド部１１が嵌挿凹部５の両側面１６，１６に線接触することから、引戸６の開閉に当たって、接触抵抗が少なくきわめて滑らかな走行が得られるものである。
【００１６】
次に、本発明の異なる実施の形態を図３乃至図１０に就いて説明する。
【００１７】
この発明の実施の形態におけるレール２３は前記図１および図２に示した実施の形態と同様であり、スライダー２８の構成が異なる。即ち、スライダー２８は主として頂面４０を開口させた函状のスライダー本体３２と、スライダー本体３２に内装される溝状の嵌挿部２５を備えた嵌挿部材３３と、カム３４と、操作部片３５とから構成される。
【００１８】
そして、スライダー本体３２は、二枚の対向する側壁３６、３６と、これら側壁３６、３６の両端部を塞ぐ２枚の端壁３７、３８と、これら側壁３６、３６、端壁３７、３８の底面を塞ぐ肉厚の底壁３９とによって頂面４０を開口した薄型の函状に形成されているもので、内部に中空部４１を形成している。また、対向する二つの端壁３７、３８の上部には中心に沿って前記嵌挿部材３３が嵌挿可能な幅を有する頂面４０と中空部４１とに連通している長方形の開口部４２、４２が形成されているとともに、一方の端壁３７の開口部４２の下方には、内周面が歯車状を呈する前記操作部片３５の嵌挿孔４７が形成されている。
【００１９】
また、前記嵌装部材３３は、スライダー本体３２の中空部４１の横幅よりも狭幅にして全体を略直方体形状に形成したもので、その頂面２４の中央に長手方向へ延びる溝状の嵌挿部２５を有しており、この嵌挿部２５の下部はスライダー本体３２への支持部４３となっている。
【００２０】
そして、嵌装部材３３はその頂面２４をスライダー本体３２の頂面４０と同一面となる位置において中空部４１に配置されるとともに、スライダー本体３２の両側端３６，３６およびこれに連通して嵌装部材３３の支持部４３に形成された挿通孔４５を貫通する支持杆４６により、スライダー本体３２に幅方向に移動可能に架設支持されている。
【００２１】
また、支持杆４６はスライダー本体３２の一方の側壁３６に穿設された挿通孔４４に挿入する主管７１と、他方の側壁３６に側壁３６の挿通孔４４に挿入される副ねじ７２とからなり、主管７１の内部に先端から軸線方向へ穿設された雌ねじ孔７１に副ねじ７２が螺入して構成される。
【００２２】
更に嵌装部材３３は、スライダー本体３２の端壁３７側と対向する側の下方の角部が切欠されて、端壁３７側と対向する嵌装部材３３の端壁４９の下方は上部よりスライダー本体３２内部に後退して形成されている。
【００２３】
この後退した端壁４９に嵌挿部材３３の長手方向に延びる断面が楕円形の係合孔５０が穿設されている。そして、この内部へ後退した端壁４９と、スライダー本体３２の端壁３７の下部と、スライダー本体３２の底壁３９と、嵌挿部材３３の上部によって囲まれる室５１が形成される。
【００２４】
また、前記カム３４の本体５２には本体５２と同径または小径で表面にドライバ等の工具を差し込む係止溝５６を有する歯車状の係止突起５５を呈する操作部片３５が固着されており、この操作部片３５が前記スライダー本体３２の一方の端壁３７に形成された嵌挿孔４７に嵌挿している。
【００２５】
更に、前記室５１にはカム３４がその中心軸線において回転可能に装入されている。このカム３４は円形の本体５２と、この本体５２の中心から偏心して突設された軸５３とからなり、この軸５３が前記端壁４９の係合孔５０に遊嵌されている。また、嵌挿部材３３の端壁４９とカム３４の本体５２との間にはカム３４を操作孔４７を形成した端壁３７側へ付勢させるばね５４が装入され、本体５２が端壁３７の裏面に圧着している。
【００２６】
そして、ドライバ等の工具を係止溝５６に差し込んで、操作部片３５をばね５４のばね力に抗して室５１の内部に押し込み、左右いずれかの方向へ回すと、カム３４が回動して軸５３が係合孔５０内を移動して嵌挿部材３３を幅方向へ摺動させるのである。即ち、ドライバ等の工具を操作部片３５を押し込んで回すことにより、カム３４の動作によって嵌挿部２５をスライダー本体３２の幅方向に摺動させて、嵌挿部２５の幅方向の調整が行われるのである。
【００２７】
尚、本実施の形態では、カム３４の軸５３は本体５２の下方に位置して、支持杆４６の下方に穿設された係合孔５０と係合している。従って、操作部片３５側から見て、操作部片を押して右側へ回すと嵌挿部材２５は左へ、左側へ回すと嵌挿部材２５は右へ摺動する。
【００２８】
そして、嵌挿部材２５を適切な位置に調節した時点で、操作部片３５への押圧力を解除するとばね５４の付勢力でカム３４と操作部片３５が元の位置に戻り、操作部片３５の係止突起５５と嵌挿孔４７の係止部４８とが嵌合して、カム３４が所定位置で固定される。
【００２９】
殊に、本実施の形態では厚さ方向の位置調整を分かりやすくするために、操作体３５を備えた端壁３７の表面には、押し回し、右、左の表示６０が施されている。
【００３０】
以上のように構成された本実施の形態におけるスライダー２８は、図５に示すように前記図１に示した実施の形態の場合と同様に引戸２６の頂面２７と走行方向と直交する木口面５７との角部５８に形成された凹形状の嵌合部５９に埋設するのであるが、このとき嵌挿部２５の頂面２４を引戸２６の頂面２７と同一面に、スライダー本体３２の操作部片３５を備えた側の端壁３７を木口面５７側と同一面に、更にスライダー２８の幅方向の中心と引戸２６の厚さ方向の中心とを一致させて取り付け、底壁３９に固定ねじ７０をもって固定する。
【００３１】
このように本実施の形態ではスライダー２８を取り付けた引戸２６を、図４に示すように前記実施の形態と同様にスライダー２８の嵌挿部２５にレール２３のガイド部３１を嵌合させて立て付けるもので、ガイド部３１と嵌挿部２５とは摺動可能に嵌合され、前記実施の形態と同様に円滑な開閉操作が可能である。
【００３２】
また、引戸２６を立て付けた状態で端壁３７の操作部片３５を押して操作部片３５を嵌挿孔４７との嵌合状態を解除するとともに、そのままの状態で操作部片３５を回動させて嵌挿部２５を幅方向に移動させることにより、スライダー２８における引戸２６の厚さ方向における取り付け位置を調整することができる。図７は嵌装部材３３の嵌挿部２５が中央に位置している状態を示し、左、右の表示６０に従って操作部片３５を押し回し嵌挿部２５を左に移動させた状態が図８であり、右に移動させた状態が図９である。
【００３３】
以上のように構成した本実施の形態は、ガイド部３１が嵌挿部２５の両端面６８，６８とほぼ線接触することから、引戸２６の開閉にあたって、抵抗が少なくきわめて滑らかな走行が得られるという効果があるとともに、殊に、操作部片３５を回すことにより、ガイド部３１を嵌合させた嵌挿部２５を引戸２６の厚さ方向へ調整して立て付けることが可能となるものである。
【００３４】
尚、本実施の形態では、操作部片３５はその周面に歯車状の係止突起５５を形成し、操作孔４７の歯車状の係止部４８と噛み合わせて嵌合させることにより、確実にして安定した嵌合状態が得られ、これがカム３４の位置固定につながる効果を生み出すが、本発明はこの構成に限定されない。
【００３５】
例えば、図１０に示されるように、操作部片６１を略円錐台状に形成して、広幅な面を端壁３７の内面側に、狭幅な面を端壁３７の表面に露出させて端壁３７に嵌合させる構成、など他の構成であってもよい。
【００３６】
また、本実施の形態では、嵌挿部２５を幅方向に摺動させるために、カム３４や支持杆４６を用いて構成したが、本発明はこの構成に限定されず、嵌挿部２５がスライダー本体３２に対して幅方向に摺動可能な構成ならばいずれの手段を採っても差し支えないものである。
【００３７】
尚、前記二つの実施の形態では、一枚の引戸６（２６）の場合について説明したが、本発明は図１１に示されるように、複数枚の引き違いの引戸６２，６２の場合において適用される。この場合には、レール６３は例えば図示したように端面コの字形に形成されるもので、上部の幅方向の部材が鴨居６４への取付片６５となり、この取付片６５の両端から二枚の脚片６６，６６が垂設されて、この脚片６６，６６の下端にそれぞれガイド部６７，６７が備えられる。
【００３８】
更にまた、レール６９は断面が逆鍵孔形状を呈していればよく、例えば図１２に示したように端面Ｔ字形に構成すること、その他、レールはさまざまな端面形状のものが本発明に適用される。
【００３９】
そして、前記各実施の形態ではガイド部１１（３１，６７）は略円形であるが、幅方向に細長い端面楕円形とすることも可能であり、この場合には更に嵌挿部５（２５）と線接触となり、より円滑な走行となるものである。
【００４０】
【発明の効果】
以上のように本発明は、下端に細長円柱状のガイド部を備えた鴨居に取り付けられる断面逆鍵孔形状のレールと前記ガイド部を摺動可能に嵌合させる溝状の嵌挿部が頂面に形成された引戸の頂面に取り付けられるスライダーとからなり、互いに嵌挿されるスライダーとレールとが線接触することになり、その結果、引戸は抵抗が少なくきわめて滑らかに開閉する。
【００４１】
しかも、スライダーを嵌挿部とスライダー本体とに別体に構成して、嵌挿部をスライダー本体に対して幅方向へ調整可能に構成した場合には、滑らかな走行だけでなく、嵌挿部が引戸の厚さ方向への調整も行えるもので、引戸の下端の戸車を幅方向への調整と相俟って、引戸全体が傾くことなく、良好な立て付け調整が行えるガイド装置を提供するものである。

It is formed in a thin box shape having a top surface 40 opened by a thick bottom wall 39 that closes the bottom surface, and a hollow portion 41 is formed inside. A rectangular opening 42 communicating with a top surface 40 and a hollow portion 41 having a width in which the fitting member 33 can be fitted along the center is formed at the upper part of the two end walls 37 and 38 facing each other. , 42 are formed, and an insertion hole 47 of the operation part piece 35 whose inner peripheral surface has a gear shape is formed below the opening 42 of one end wall 37.
[0019]
The fitting member 33 is formed in a substantially rectangular parallelepiped shape so as to be narrower than the horizontal width of the hollow portion 41 of the slider main body 32, and has a groove-like fitting extending in the longitudinal direction at the center of the top surface 24. An insertion portion 25 is provided, and a lower portion of the insertion insertion portion 25 serves as a support portion 43 for the slider main body 32.
[0020]
The fitting member 33 is disposed in the hollow portion 41 at a position where the top surface 24 is flush with the top surface 40 of the slider main body 32, and communicates with both side ends 36 and 36 of the slider main body 32. The slider main body 32 is supported by a support rod 46 penetrating the insertion hole 45 formed in the support portion 43 of the fitting member 33 so as to be movable in the width direction.
[0021]
The support rod 46 includes a main pipe 71 that is inserted into the insertion hole 44 formed in one side wall 36 of the slider body 32, and a secondary screw 72 that is inserted into the insertion hole 44 of the side wall 36 on the other side wall 36. A sub screw 72 is screwed into a female screw hole 71 bored in the axial direction from the tip inside the main pipe 71.
[0022]
Further, the fitting member 33 is cut out at the lower corner on the side facing the end wall 37 side of the slider body 32, and the lower side of the end wall 49 of the fitting member 33 facing the end wall 37 side is lower than the slider. It is formed to recede inside the main body 32.
[0023]
An engagement hole 50 having an elliptical cross section extending in the longitudinal direction of the fitting member 33 is formed in the retracted end wall 49. A chamber 51 surrounded by the end wall 49 retracted into the interior, the lower portion of the end wall 37 of the slider body 32, the bottom wall 39 of the slider body 32, and the upper portion of the fitting member 33 is formed.
[0024]
An operation piece 35 that has a gear-like locking projection 55 having a locking groove 56 for inserting a tool such as a screwdriver on the surface thereof is fixed to the main body 52 of the cam 34. The operation part 35 is inserted into an insertion hole 47 formed in one end wall 37 of the slider main body 32.
[0025]
Further, a cam 34 is inserted into the chamber 51 so as to be rotatable about its central axis. The cam 34 includes a circular main body 52 and a shaft 53 that protrudes eccentrically from the center of the main body 52, and the shaft 53 is loosely fitted in the engagement hole 50 of the end wall 49.
