Description

【0001】
【発明の属する技術分野】
本発明は、建築物の床面に設けられ、床材を昇降自在に調整して固定するために使用される床下材支持具に関するものである。
【0002】
【従来の技術】
従来、上記のような床下材支持具としては、登録実用新案3046733号公報に記載されているようなものが存在している。この床下材支持具は、図11に示すように、内周に雌ねじ106が設けられ、下端に鍔部108が形成された筒状体107に、筒状体107と鍔部108とに亘って所定間隔に補強リブ109を設けたベース部材102と、外周に雄ねじ112を設けベース部材102の雌ねじ106に螺合する柱状の調整部材103とが螺合され、コンクリート床面に昇降自在に立設されるようになっている。
【0003】
上記調整部材103を上記ベース部材102に固定するため、環状のストッパー105が、調整部材103を挿通させるように形成されている。当該ストッパー105の内周の下端面には上記補強リブ109に嵌合する凹所115が設けられ、凹所115より上方の内周には突起116が設けられている。そして、上記調整部材103には、縦方向に上記突起116と嵌合する摺動溝113が形成されている。
【0004】
上記のような床下材支持具を使用した場合、下記のような方法で上記調整部材103を上記ベース部材102に固定する。まず、調整部材103の摺動溝113にストッパー105の突起116を嵌合させた状態で、ストッパー105を調整部材103に挿通させる。次に、ストッパー105の凹所115が補強リブ109の上部に接触しないようストッパー105をベース部材102より持ち上げた状態のまま調整部材3をベース部材102に螺合させ、螺合の度合いを調節することにより所望の高さに昇降調整する。最後に、ストッパー105を下降させて、その凹所115を補強リブ109の上部に嵌合させることにより、ストッパー105は調整部材103及びベース部材102と相対回転しないように嵌合する。すなわち、ストッパー105により上記調整部材103と上記ベース部材102との相対回転が阻止され、上記両部材が固定される。
【0005】
【発明が解決しようとする課題】
上記のような床下材支持具を使用した場合、調整部材103をベース部材102に螺合させ、両部材を相対回転させて所望の高さに昇降調整するとき、ストッパー105の凹所115が補強リブ109の上部に接触すると相対回転することが出来なくなる。したがって、凹所115が補強リブ109の上部に接触しないようストッパー105をベース部材102より持ち上げた状態のまま上記相対回転を行う必要があり、その作業の手間が負担となっていた。よって本発明は、上記調節部材とベース部材との高さや長さの調節及び固定作業を行う手間を低減することが出来る床下材支持具を提供するものである。
【0006】
【課題を解決するための手段】
本発明は、建築物の床下材を支持する床下材支持具であって、当該床下材支持具は、建築物の床下材を支持する支持脚体と、当該支持脚体が取り付けられるベース部材と、上記支持脚体と上記ベース部材との相対移動を規制する固定状態及び上記相対移動を許容する解放状態に切り替え可能なよう両部材に嵌合する固定部材とを有し、上記支持脚体及び上記ベース部材のうち少なくとも一方は、筒状に形成され、かつ、その内周に他方の部材に螺着可能な雌ねじ部が設けられ、他方の部材には上記雌ねじ部に螺着する雄ねじ部が設けられ、上記固定部材は、上記解放状態では、上記雌ねじ部が設けられた部材に対する回転軸方向の相対移動が規制され、上記雄ねじ部が設けられた部材に対する回転軸方向の相対移動が許容され、上記雌ねじ部が設けられた部材及び上記雄ねじ部が設けられた部材のうちいずれか一方の部材に対する相対回転が阻止され、他方の部材に対する相対回転が許容されるように嵌合し、この解放状態で許容されている相対回転を阻止することにより当該固定部材が上記固定状態へと切り替えられることを特徴とする床下材支持具である。
【0007】
このような床下材支持具を用いた場合、下記のような方法で床下材支持具の高さを調節し、上記支持脚体と上記ベース部材との固定を行うことが可能である。
【0008】
まず、当該支持脚体及び当該ベース部材に備えられた上記雄ねじ部と上記雌ねじ部とを螺合させた後、上記固定部材を支持脚体及びベース部材に嵌合させる。
【0009】
次に、上記固定部材を解放状態にした状態で、固定部材と、上記雌ねじ部が設けられた部材及び上記雄ねじ部が設けられた部材のうち上記固定部材と相対回転可能な部材(回転部材)とを相対回転させることにより、上記雄ねじ部と雌ねじ部とを相対回転させ、ねじ推進させる。
【0010】
このとき、上記固定部材は、上記解放状態では、上記雌ねじ部が設けられた部材に対する回転軸方向の相対移動が規制され、上記雄ねじ部が設けられた部材に対する回転軸方向の相対移動が許容され、上記回転部材との相対回転が許容されている。したがって、上記固定部材を支持脚体及びベース部材に嵌合させた状態のままでも、ねじ推進が阻害されることはなく、上記雄ねじ部と雌ねじ部との高さ、すなわち上記支持脚体とベース部材との高さを調節することが可能である。よって、かかる場合において従来のようにわざわざ固定部材を持ち上げて上記相対回転を行う必要がない。
【0011】
最後に、高さ調節が終わった状態で固定部材と上記回転部材との相対回転を阻止するだけで上記ねじ推進を阻止することができ、上記床下材支持具を固定することが可能である。また、上記相対回転をさせているとき上記固定部材は回転軸方向について雌ねじが設けられた部材との相対移動が規制されている。したがって固定状態に切り替えるとき、わざわざ当該固定部材を回転軸方向に移動させる必要がない。よって、上記支持脚体とベース部材との高さ調節及び固定作業を行う手間を低減することが出来る。
【0012】
また、請求項2の発明のように、上記固定部材に、上記解放状態では、上記雌ねじ部が設けられた部材に対する回転軸方向の相対移動が規制され、上記雄ねじ部が設けられた部材に対する回転軸方向の相対移動が許容され、上記雌ねじ部が設けられた部材及び上記雄ねじ部が設けられた部材のうちいずれか一方の部材に対する相対回転が阻止され、他方の部材に対する相対回転が許容されるように上記支持脚体及び上記ベース部材の外周に嵌合可能な本体部と、当該本体部と接続され、上記雌ねじ部が設けられた部材及び上記雄ねじ部が設けられた部材のうちいずれか一方の部材と上記本体部とが相対回転することを許容する状態と当該相対回転を規制する状態とに切替可能な切替部材とを備えるようにすると、上記の切替作業を行う手間をより低減することが可能となる。
【0013】
なお、請求項3の発明は、上記切替部材は、上記回転部材と係合可能な係合部を有すると共に、上記係合部が上記回転部材と係合して上記相対回転を阻止する位置と、上記係合部が上記回転部材から外れて上記相対回転を許容する位置とに移動可能となるよう上記固定部材の本体部に連結されている床下材支持具である。
【0014】
この場合、上記切替部材は、上記固定部材に連結されているため、誤って上記固定部材を紛失したりすることがない。また、当該切替部材は、上記係合部と上記回転部材とを係合させるか否かにより上記相対回転の許容及び阻止を切り替えることが出来るため、上記相対回転を阻止するとき、わざわざ上記固定部材に上記切替部材を取り付けて、その後に上記相対回転を阻止するといった作業をとる必要がない。したがって、上記の切替作業を行う手間をより低減することが可能となる。
【0015】
請求項4の発明は、上記回転部材の外周には全周に亘り凹凸部が形成され、上記切替部材の係合部は任意の位置で上記凹凸部に係合する形状を有するものである。
【0016】
この場合、上記回転部材の外周には全周に亘り凹凸部が形成されているため、上記係合部は任意の位置で上記凹凸部と係合させることが可能である。したがって、上記床下材支持具を任意の高さに設定することが可能となる。
【0017】
請求項5の発明は、上記切替部材が上記本体部に回転可能なように連結され、この連結部分を支点として回転することにより上記係合部と上記回転部材の外周とが係合して上記相対回転を阻止する位置と上記係合部と上記回転部材の外周とが係合しない位置とに移動可能となる床下材支持具であって、上記切替部材は、上記支点から上記係合部とは異なる方向に延びるレバー部を有し、その支点からレバー部先端までの距離が当該支点から上記係合部までの距離よりも大きい床下材支持具である。
【0018】
この場合、支点からレバー部先端までの距離が当該支点から上記係合部までの距離よりも大きいため、小さな力でも上記切替部材を回転させ、上記係合部と上記回転部材の外周とが係合する位置と係合しない位置とに切り替えることが可能となる。したがって、上記の切替作業を行う手間をより低減することが可能となる。
【0019】
なお、請求項6の発明のように、上記切替部材が、上記固定部材の本体部を縮径させて上記回転部材に圧接させることにより、上記回転部材と上記本体部との相対回転を阻止する位置と、上記本体部について上記縮径させた状態から拡径させることにより、当該本体部と接続し、上記回転部材とが接触しない状態にすることにより上記相対回転を可能とする位置とに移動可能となるよう上記固定部材の本体部に連結されているようにしても、上記切替部材の位置を移動させるのみで上記固定部材と上記回転部材との相対回転を規制したり許容したりすることが可能なため、請求項2の場合と同様、上記の切替作業を行う手間を低減することが可能となる。
【0020】
また、請求項7の発明は、上記切替部材が、上記回転部材と係合可能な係合部を有すると共に、上記係合部が上記回転部材と係合して上記相対回転を阻止する位置と、上記係合部が上記回転部材から外れて上記相対回転を許容する位置とに移動可能となるよう上記固定部材の本体部に連結されている床下材支持具であって、上記相対回転を阻止する位置では、さらに上記固定部材の本体部を縮径させて上記回転部材に圧接させることにより、上記本体部と上記回転部材との相対回転を阻止することを特徴とする請求項3乃至5のいずれかに記載の床下材支持具である。
【0021】
この場合、上記相対回転を阻止する位置においては、上記係合部が上記回転部材と係合しているだけでなく、上記固定部材の本体部も縮径して上記回転部材に圧接している。したがって、上記固定部材と上記回転部材との固定は、上記切替部材の係合部と上記回転部材との係合力に加え、上記固定部材の本体部と上記回転部材との圧着力も加わる。よって、上記固定状態において上記支持脚体とベース部材との固定をより安定させることが出来る。
【0022】
【発明の実施の形態】
本発明の実施形態について、図1〜図10を用いて説明する。ただし、本発明は以下の実施形態に限定されることはない。
【0023】
本実施形態の床下材支持具1は、図1の通り、支持脚体10と、第一ベース部材20と、第二ベース部材30と、ストッパー40(固定部材に相当)とを備えている。そして、第一ベース部材20の底面21が、コンクリート、束石等の地盤部分と接し、第二ベース部材30の上面に設置された平面部31及び側面部32が、建築物の床下材を保持することにより、建築物の床下部分は床下材支持具1に支持されている。
【0024】
支持脚体10の両端には図2に示す雄ねじ部11が設けられており、その雄ねじ部11に、第一ベース部材20及び第二ベース部材30が螺着している。そして、支持脚体10の外周と第一ベース部材20の外周、及び、支持脚体10の外周と第一ベース部材20と外周を覆うようにストッパー40が各々取り付けられている。
【0025】
次に図2を用いて、支持脚体10及び第一ベース部材20及び第二ベース部材30について説明する。
【0026】
支持脚体10は、軸状に形成され、その外周両端に形成された雄ねじ部11、11と、雄ねじ部11以外の外周部分に形成された軸部12とを有し、この軸部12に摺動溝13(図1参照)が軸方向に伸びるよう設けられている。また、雄ねじ部11は、その最大外径が軸部12より大きくなるよう形成されている。
【0027】
第一ベース部材20は、筒状に形成され、その内周には上記雄ねじ部11と螺着可能な雌ねじ部25が設けられている。また、第一ベース部材20の一端(本図では下端に相当)には、地盤と接触して荷重を支える底面21が鍔状に形成され、他端(本図では上端に相当)には、全周に亘って凹凸部26が設けられている。そして、凹凸部26に隣接する領域(本図では凹凸部26に隣接する下側の領域)には、上記凹凸部26より小径の凹部27が全周に亘って設けられている。
【0028】
第二ベース部材30は、第一ベース部材20と同様に筒状に形成され、その内周についても、第一ベース部材20と同様、上記雄ねじ部11と螺着可能な雌ねじ部35が設けられている。また、第二ベース部材30の一端(本図では上端に相当)には略長方形の形状の平面部31が設けられ、平面部31の対向する二辺には側面部32が立設されている。そして、平面部31の上に建築物の床下材を置くと、側面部32によってその床下材は狭持されるようになっている。また、他端(本図では下端に相当)には、第一ベース部材20の凹凸部26と同様、全周に亘って凹凸部36が設けられ、さらに、その隣接する領域についても、第一ベース部材20と同様に上記凹凸部36より小径の凹部37が全周に亘って設けられている。
【0029】
ストッパー40は、図1に記載のように本体部41と切替レバー42(切替部材に相当)とを有する。以下本体部41においては、図3(a)、図3(b)を用いて説明する。
【0030】
本体部41は、環状体の周方向の一部が分断された形状を有し、その分断された箇所の両端には各々レバー保持部414、414が設けられている。そして、その環状の部分には、上記支持脚体10の軸部12の外径よりも大きくて、上記雄ねじ部11の最大外径よりも小さい内径をもつ第一嵌合部411と、上記第一嵌合部より大きい内径を持つ第二嵌合部412とが軸方向に並んでいる。第一嵌合部411の内周には、軸方向に伸び、かつ、上記支持脚体10の摺動溝13に嵌合可能な突起部416が設けられている。また、第二嵌合部412の内周の縁には内周側に突起するように凸部413が設けられている。なお、レバー保持部414、414には、若干括れたU字形に形成されたレバー嵌着部415が設けられている。また、本体部41の素材は、合成樹脂等のように、弾性変形させることが可能な素材を使用している。
【0031】
次に、切替レバー42について図4を用いて説明する。切替レバー42は、係合部材421とレバー部422とを有している。そして、レバー部422の一端側には、係合部材421を両側から狭持する狭持部425、425が設けられている。係合部材421は、略L字型に形成されており、その一端がレバー部422と連結されている。また、他端には第一ベース部材20の凹凸部26に嵌合可能なよう、凹凸形状に成形された係合部423が設けられている。すなわち、係合部423と、レバー部422とは略90度の角度をなして形成されている。そして、係合部材421の折れ曲がった部分から狭持部425、425に向けて各々支点軸424、424が設けられることにより、係合部材421と狭持部425、425とは連結されている。なお、支点軸424からレバー部422の先端までの距離の方が、支点軸424から係合部423との距離より大きくなるように形成されている。
【0032】
以下、図2、図5、図6を用いて、床下材支持具1の組み立て方法を説明する。なお、以下の説明は、支持脚体10と第一ベース部材20との組み立てにおいて説明しているが、支持脚体10と第二ベース部材30との組み立てについても略同等であるため、第二ベース部材30の構成要素のうち、第一ベース部材20の構成要素に対応する部分に関しては、括弧を付して記載することとし、その重複説明を省略する。
【0033】
工程1(図2参照):支持脚体10の雄ねじ部11を、第一ベース部材20(第二ベース部材30)の雌ねじ部25(雄ねじ部35)に螺着する。
【0034】
工程2(図5、図6参照):ストッパー40の本体部41を弾性変形させてレバー保持部414、414の間隔を広げ、本体部41を上記支持脚体10の外周及び第一ベース部材20(第二ベース部材30)の外周に取り付ける。このとき、図6に示すように、本体部41の第一嵌合部411は支持脚体10に嵌合し、第二嵌合部412は第一ベース部材20(第二ベース部材30)に嵌合する。具体的には、第一嵌合部411と支持脚体10とは、第一嵌合部411が支持脚体10の軸部12を覆い、突起部416が摺動溝13に嵌合する(図7(a)参照)ように装着される。この場合、摺動溝13は、前述のとおり軸方向に伸びるように設けられているため、突起部416と摺動溝13とは、相対回転は出来ないが、軸方向への移動は可能となっている。すなわち、ストッパー40の第一嵌合部411と、支持脚体10とは、その相対回転が規制され、かつ、回転軸方向への相対移動が可能である状態で嵌合している。そして、第二嵌合部412と第一ベース部材20(第二ベース部材30)とは、第二嵌合部412が凹凸部26(凹凸部36)の外周を覆い、その内周に設けられた凸部413が凹部27(凹部37)に嵌合するように装着される。この場合、凹部27(凹部37)は、前述のとおり第一ベース部材20(第二ベース部材30)の全周に亘って設けられているため、凸部413と凹部27とは相対回転可能であり、かつ、軸方向への相対移動が規制されるように嵌合している。すなわち、ストッパー40の第二嵌合部412と、第一ベース部材20(第二ベース部材30)とは、その相対回転が可能で(したがって、本実施形態においては、第一ベース部材20(第二ベース部材30)が回転部材に相当)、かつ、回転軸方向への相対移動が規制されるよう嵌合している。
【0035】
工程3(図6参照):本体部41のレバー保持部414に切替レバー42を取り付ける。このとき、切替レバー42のレバー保持部414への取り付けは、レバー嵌着部415に切替レバー42の支点軸424を嵌着することにより行われる。この場合、切替レバー42は、支点軸424を中心に回転可能となっている。
【0036】
次に、図7〜図10を用いて床下材支持具1の長さを調節する手順について説明する。図7(a)、(b)は、上記ストッパー40が、支持脚体10と第一ベース部材20(第二ベース部材30)との相対移動を規制するように嵌合している状態、すなわち固定状態を示したものである。この状態では、切替レバー42は、その係合部材421の係合部423が第一ベース部材20(第二ベース部材30)の凹凸部26(凹凸部36)に係合しており、第一ベース部材20(第二ベース部材30)とストッパー40との相対回転を係止している。加えて、ストッパー40と支持脚体10との相対回転は突起部416及び摺動溝13を介して係止されているため、支持脚体10と第一ベース部材20(第二ベース部材30)との相対移動は規制されている。
【0037】
以下に床下材支持具1の長さを調節する手順について説明する。
【0038】
手順1(図7、図8参照):図7(a)、(b)の状態から、切替レバー42のレバー部422を引上げることにより、切替レバー42を支点軸424を中心に回転させて、図8(a)、図8(b)に記載の状態とする。このとき、切替レバー42の係合部423は、上記回転に伴い下側に移動し、凹凸部26から外れる。すなわち、切替レバー42の係合部423と凹凸部26との係合状態は解除され、上記ストッパー40と上記第一ベース部材20(第二ベース部材30)との相対回転が可能となるため、支持脚体10と上記第一ベース部材20(第二ベース部材30)との相対回転も可能となる(解放状態に相当)。そして、支持脚体10及び第一ベース部材20(第二ベース部材30)を相対回転させてねじ推進を行う。この場合、ストッパー40の突起部416は支持脚体10の摺動溝13に沿って軸方向に移動する。すなわち、ストッパー40と支持脚体10とは軸方向に相対移動することとなる。また、ストッパー40の凸部413と第一ベース部材20(第二ベース部材30)の凹部27(凹部37)とは相対回転可能であり、かつ、軸方向への相対移動が規制されるように嵌合しているため、ストッパー40と第一ベース部材20(第二ベース部材30)とは、回転軸方向については相対移動しない。
【0039】
手順2(図9参照):上記解放状態で、床下材支持具1が所望の長さとなるまで上記ねじ推進を継続する。この場合、ねじ推進の状態にかかわらず、ストッパー40と第一ベース部材20(第二ベース部材30)とは、回転軸方向について相対移動しない。
【0040】
手順3(図10参照):図9の状態から、切替レバー42のレバー部422を引き下げることにより、再び、切替レバー42の係合部423を第一ベース部材20(第二ベース部材30)の凹凸部26(凹凸部36)に係合させ、第一ベース部材20(第二ベース部材30)とストッパー40との相対回転を係止する。この場合、ストッパー40と、支持脚体10とは、相対回転を規制する状態で嵌合しているため、第一ベース部材20(第二ベース部材30)とストッパー40との相対回転を係止するだけでねじ推進が阻止され、開放状態から固定状態へと切り替わる。
【0041】
以上より、上記のような床下材支持具1を用いた場合、上記開放状態では、ストッパー40と第一ベース部材20(第二ベース部材30)とは相対回転可能であり、かつ、ストッパー40と支持脚体10とは、回転軸方向への相対移動が可能である状態で嵌合している。したがって、上記ストッパー40を支持脚体10及び第一ベース部材20(第二ベース部材30)に嵌合させた状態のままでも、ねじ推進が阻害されることはなく、床下材支持具1の長さを調節することが可能である。よって、かかる場合において従来のようにわざわざストッパーを持ち上げて上記相対回転を行う必要がない。
【0042】
また、上記相対回転をさせているとき、ストッパー40は第一ベース部材20(第二ベース部材30)に対して回転軸方向については相対移動しない。したがって固定状態に切り替えるとき、わざわざストッパー40を回転軸方向に移動させ、第一ベース部材20に当接させるといった作業を行う必要がない。
【0043】
さらに、ストッパー40と支持脚体10とはそもそも相対回転が規制されているため、ストッパー40と第一ベース部材20(第二ベース部材30)との相対回転を阻止したり、許容したりするだけで上記ねじ推進を阻止したり許容したりすることが可能となる。すなわち、かかる作業を行うだけで、上記固定状態と開放状態とを切り替えることが可能となる。
【0044】
したがって、支持脚体10と第一ベース部材20(第二ベース部材30)との長さや高さの調節及び固定作業を行う手間を低減することが出来る。
【0045】
なお、切替レバー42は、レバー嵌着部415に切替レバー42の支点軸424が嵌着することによりストッパー40に連結されているため、誤って切替レバー42を紛失したりすることがない。
【0046】
また、切替レバー42を切替レバー42のレバー部422を引上げることにより、支点軸424を中心に回転させるだけで、切替レバー42の係合部423を第一ベース部材20(第二ベース部材30)の凹凸部26(凹凸部36)に係合させたり、その係合を解除したりすることが出来る。したがって、上記解放状態と固定状態との切替作業を行う手間をより低減することが可能となる。
【0047】
さらには、凹凸部26(凹凸部36)は、第一ベース部材20(第二ベース部材30)の外周の全周に亘り形成されているため、切替レバー42の係合部423は任意の位置で凹凸部26(凹凸部36)と係合させることが可能である。したがって、床下材支持具1を任意の高さに設定することが可能となる。
【0048】
なお、支点軸424からレバー部422先端までの距離が支点軸424から係合部423までの距離よりも大きいため、小さな力でも切替レバー42を回転させて係合部423と凹凸部26(凹凸部36)とが係合する位置と係合しない位置とに切り替えることが可能となる。したがって、上記の切替作業を行う手間をより低減することが可能となる。
【0049】
以下の実施形態において、第1実施形態と同一部分には同一符号を付して示し、その重複説明を省略する。
【0050】
その他実施形態
(1) 本発明では、上記解放状態において、支持脚体10とストッパー40との相対回転を規制し、第一ベース部材20及び第二ベース部材30を含めたベース部材とストッパー40との相対回転を許容する代わりに、支持脚体10とストッパー40との相対回転を許容し、上記ベース部材とストッパー40との相対回転を阻止するようにしてもよい。
【0051】
具体的に、支持脚体10とストッパー40との相対回転を可能にする手段としては、図1の摺動溝13及び図4(a)の凸部416をなくし、かつ、ベース部材とストッパーとの相対回転を含めた相対移動を阻止するように、各々の部材に凹みや突起を設けて両部材が嵌合するようにしたり、上記ストッパーとベース部材とを一体成型したりする等が考えられる。
【0052】
この場合も、支持脚体10とストッパー40との相対回転を阻止することにより、上記解放状態から固定状態、すなわち支持脚体10とベース部材とが固定される状況にすることができる。このように支持脚体10とストッパー40との相対回転を阻止するための構成としては、例えば第一実施形態のようにベース部材に凹凸部26(凹凸部36)を設ける代わりに、支持脚体10の外周に同様の凹凸部を設け、切替レバー42の係合部422がこの凹凸部に嵌着するようなものが考えられる。
【0053】
このような床下材支持具を用いた場合でも、上記開放状態では、ストッパーと支持脚体とは、相対回転も、回転軸方向への相対移動も可能であるため、第一実施形態の場合と同様、上記ストッパーを支持脚体及びベース部材に嵌合させた状態のままでも、ねじ推進が阻害されることはなく、床下材支持具の長さを調節することが可能である。よって、かかる場合において従来のようにわざわざストッパーを持ち上げて上記相対回転を行う必要がない。
【0054】
また、上記相対回転をさせているとき、ストッパーはベース部材に対して回転軸方向については相対移動しないため、第一実施形態と同様、固定状態に切り替えるとき、わざわざストッパーを回転軸方向に移動させ、ベース部材に当接させるといった作業を行う必要がない。
【0055】
さらに、ストッパーとベース部材とは相対回転をも規制されているため、ストッパーと支持脚体との相対回転を阻止したり、許容したりするだけで上記ねじ推進を阻止したり許容したりすることが可能となる。すなわち、かかる作業を行うだけで、上記固定状態と開放状態とを切り替えることが可能となる。
【0056】
したがって、第一実施形態と同様、支持脚体とベース部材との長さや高さの調節及び固定作業を行う手間を低減することが出来る。
【0057】
しかしながら、本実施形態のように、支持脚体10のような雄ねじ部12が設けられた部材に凹凸部を設ける場合より、第一実施形態のように雌ねじ部25が設けられた部材(第一実施形態では第一ベース部材20及び第二ベース部材30に相当)に凹凸部を設ける方が、ストッパー40と雌ねじ部25が設けられた部材とは軸方向への相対移動が阻止されているため、軸方向について凹凸部を設ける範囲が短くて済むためより好ましい。
【0058】
(2) また本発明では、上記固定状態において、上記固定部材と上記回転部材との固定は、上記切替部材の係合部と上記回転部材の凹凸部との係合によるものに限らず、上記固定部材の本体部と上記回転部材との圧着による力も加わるようにして、上記支持脚体とベース部材との固定をより安定させるようにしてもよい。具体的には以下のものが考えられる。
【0059】
図3(a)のストッパー41のレバー保持部414、414について、その間隔は一定のままで、先端から基端に向けて厚肉となるようにする。そして、図4に記載の切替レバー42の支点軸424をレバー嵌着部415に嵌着した後、レバー部422を引き下げる際に、レバー保持部414、414の外側面と切替レバー41の狭持部425、425の内側面とを接触させるような構成とする。
【0060】
このような構成では、切替レバー422を引き下げるに伴い、狭持部425、425はレバー保持部414、414の基端側に接触することとなる。さらには、レバー保持部414は基端に向けて厚肉となっているため、狭持部425、425がレバー保持部414、414の基端側に接触していくことに伴い、レバー保持部414、414の間隔が狭くなることとなる。すなわち、レバー部422を引き下げるに伴いストッパー41の径が狭くなり、支持脚体10及び第一ベース部材20(第二ベース部材30)を締め付けることになる。
【0061】
よって、切替レバー422を引き下げると、上記相対回転は、係合部423と凹凸部26(凹凸部36)との係合力のみならず、上記締め付けによる力によっても阻止されるため、支持脚体とベース部材20との固定をより安定させることが可能となる。
【0062】
(3) 必ずしも、支持脚体10に雄ねじ部12を設け、第一ベース部材20(第二ベース部材30)に雌ねじ部25(雌ねじ部35)、凹凸部26(凹凸部36)、凹部27(凹部37)を設ける必要はない。例えば、支持脚体10に雌ねじ部、凹凸部、凹部を設け、第一ベース部材20(第二ベース部材30)に雄ねじ部を設けることも可能である。
【0063】
(4) 本発明の切替部材としては、切替レバー42の代わりにボルト、ナット等のような締付治具をレバー嵌着部415、415間に亘って取り付けるようにしてもよい。この場合、当該締付治具を締め付けることにより、レバー嵌着部415、415間の間隔を狭め、本体部42と上記回転部材との相対回転を阻止する。また、当該締付治具を緩めることにより、レバー嵌着部415、415間の間隔を広げ、本体部42と上記回転部材との相対回転を許容する。
【0064】
(5) 本発明のベース部材は、必ずしも支持脚体の両端に設ける必要はなく、片側のみでもよい。例えば、支持脚体10と第一ベース部材20、又は、支持脚体10と第二ベース部材30とを一体に形成し、ベース部材を一つにしてもよい。
【0065】
【発明の効果】
本発明の床下材支持具を用いた場合、上記解放状態では、上記雌ねじ部が設けられた部材に対する回転軸方向の相対移動が規制され、上記雄ねじ部が設けられた部材に対する回転軸方向の相対移動が許容され、上記雌ねじ部が設けられた部材及び上記雄ねじ部が設けられた部材のうちいずれか一方に対する相対回転が許容されている。したがって、上記固定部材を支持脚体及びベース部材に嵌合させた状態のままでも、ねじ推進が阻害されることはなく、床下材支持具の長さを調節することが可能である。よって、かかる場合において従来のようにわざわざストッパーを持ち上げて上記相対回転を行う必要がない。
【0066】
また、上記相対回転をさせているとき、固定部材と雌ねじ部が設けられた部材とは回転軸方向について一体となって移動する。したがって固定状態に切り替えるとき、わざわざ固定部材を回転軸方向に移動させ、雌ねじ部が設けられた部材に当接させるといった作業を行う必要がない。
【0067】
さらに、上記固定部材と、上記回転部材と異なる部材とは、そもそも相対回転が規制されている。したがって、上記固定部材と上記回転部材との相対回転を阻止するだけで上記ねじ推進を阻止し、上記床下材支持具を固定することが可能である。すなわち、かかる作業を行うだけで、上記固定状態と開放状態とを切り替えることが可能となる。
【0068】
したがって、支持脚体とベース部材との長さや高さの調節及び固定作業を行う手間を低減することが出来る。

BACKGROUND OF THE INVENTION
The present invention relates to an underfloor support that is provided on a floor surface of a building and is used for adjusting and fixing a floor material so as to be movable up and down.
[0002]
[Prior art]
Conventionally, as the underfloor material support as described above, there are those described in the registered utility model No. 3046733. As shown in FIG. 11, the underfloor material support has a cylindrical body 107 in which a female screw 106 is provided on the inner periphery and a flange portion 108 is formed at the lower end, and extends between the cylindrical body 107 and the flange portion 108. A base member 102 provided with reinforcing ribs 109 at a predetermined interval and a columnar adjusting member 103 provided with a male screw 112 on the outer periphery and screwed into a female screw 106 of the base member 102 are screwed, and are erected up and down on a concrete floor surface. It has come to be.
[0003]
In order to fix the adjustment member 103 to the base member 102, an annular stopper 105 is formed so that the adjustment member 103 is inserted. A recess 115 that fits into the reinforcing rib 109 is provided on the lower end surface of the inner periphery of the stopper 105, and a protrusion 116 is provided on the inner periphery above the recess 115. The adjusting member 103 is formed with a sliding groove 113 that fits the protrusion 116 in the vertical direction.
[0004]
When the underfloor material support as described above is used, the adjustment member 103 is fixed to the base member 102 by the following method. First, the stopper 105 is inserted into the adjustment member 103 with the protrusion 116 of the stopper 105 fitted in the sliding groove 113 of the adjustment member 103. Next, the adjustment member 3 is screwed to the base member 102 while the stopper 105 is lifted from the base member 102 so that the recess 115 of the stopper 105 does not contact the upper portion of the reinforcing rib 109, and the degree of screwing is adjusted. Thus, the height is adjusted to a desired height. Finally, the stopper 105 is lowered and the recess 115 is fitted to the upper portion of the reinforcing rib 109 so that the stopper 105 is fitted so as not to rotate relative to the adjusting member 103 and the base member 102. That is, the stopper 105 prevents the adjustment member 103 and the base member 102 from rotating relative to each other, and both the members are fixed.
[0005]
[Problems to be solved by the invention]
When the underfloor material support as described above is used, the recess 115 of the stopper 105 is reinforced when the adjustment member 103 is screwed to the base member 102 and the both members are rotated relative to each other and adjusted to a desired height. When it comes into contact with the upper part of the rib 109, it cannot be rotated relatively. Therefore, it is necessary to perform the relative rotation while the stopper 105 is lifted from the base member 102 so that the recess 115 does not come into contact with the upper portion of the reinforcing rib 109, and the labor of the work is a burden. Therefore, the present invention provides an underfloor support that can reduce the labor of adjusting and fixing the height and length of the adjusting member and the base member.
[0006]
[Means for Solving the Problems]
The present invention is an underfloor material support for supporting an underfloor material of a building, and the underfloor material support includes a support leg for supporting the underfloor material of a building, and a base member to which the support leg is attached. A fixed member that fits both members so as to be switchable between a fixed state that restricts relative movement between the support leg and the base member and a release state that allows the relative movement, and the support leg and At least one of the base members is formed in a cylindrical shape, and a female screw portion that can be screwed to the other member is provided on the inner periphery thereof, and a male screw portion that is screwed to the female screw portion is provided on the other member. In the released state, the fixed member is restricted from relative movement in the rotational axis direction with respect to the member provided with the female screw portion, and is allowed to move relative to the member provided with the male screw portion in the rotational axis direction. , Female thread part Relative rotation with respect to either one of the provided member and the member provided with the male screw portion is blocked, and relative rotation with respect to the other member is allowed, and is allowed in this released state. An underfloor support, wherein the fixing member is switched to the fixed state by preventing relative rotation.
[0007]
When such an underfloor material support is used, the height of the underfloor material support can be adjusted by the following method to fix the support leg and the base member.
[0008]
First, after the male screw portion and the female screw portion provided in the support leg and the base member are screwed together, the fixing member is fitted into the support leg and the base member.
[0009]
Next, in a state where the fixing member is in a released state, the fixing member, the member provided with the female screw portion, and the member provided with the male screw portion and a member that can be rotated relative to the fixing member (rotating member) Are rotated relative to each other so that the male screw portion and the female screw portion are rotated relative to each other, and the screw is propelled.
[0010]
At this time, in the released state, the fixing member is restricted from relative movement in the rotation axis direction with respect to the member provided with the female screw portion, and is allowed to move in the rotation axis direction relative to the member provided with the male screw portion. The relative rotation with the rotating member is allowed. Therefore, even when the fixing member is fitted to the support leg and the base member, the screw propulsion is not hindered, and the height of the male screw portion and the female screw portion, that is, the support leg and the base It is possible to adjust the height of the member. Therefore, in such a case, it is not necessary to lift the fixing member and perform the relative rotation as in the prior art.
[0011]
Finally, the screw propulsion can be prevented only by preventing the relative rotation between the fixing member and the rotating member after the height adjustment is completed, and the underfloor material support can be fixed. Further, when the relative rotation is performed, relative movement between the fixing member and a member provided with a female screw is restricted in the rotation axis direction. Therefore, when switching to the fixed state, it is not necessary to move the fixing member in the direction of the rotation axis. Therefore, it is possible to reduce the labor for adjusting the height and fixing the support leg and the base member.
[0012]
According to a second aspect of the present invention, in the released state, the relative movement of the fixed member relative to the member provided with the female screw portion is restricted, and the rotation relative to the member provided with the male screw portion is restricted. Relative movement in the axial direction is allowed, relative rotation with respect to any one of the member provided with the female screw portion and the member provided with the male screw portion is prevented, and relative rotation with respect to the other member is allowed. As described above, one of the main body that can be fitted to the outer periphery of the support leg and the base member, the member that is connected to the main body and is provided with the female screw part, and the member that is provided with the male screw part If a switching member that can be switched between a state allowing the relative rotation of the member and the main body portion and a state restricting the relative rotation is provided, the trouble of performing the switching operation described above is eliminated. Ri can be reduced.
[0013]
According to a third aspect of the present invention, the switching member has an engaging portion engageable with the rotating member, and the engaging portion engages with the rotating member to prevent the relative rotation. An underfloor support that is coupled to the main body of the fixed member so that the engaging portion is disengaged from the rotating member and can be moved to a position allowing the relative rotation.
[0014]
In this case, since the switching member is connected to the fixing member, the fixing member is not accidentally lost. In addition, since the switching member can switch between allowing and blocking the relative rotation depending on whether or not the engaging portion and the rotating member are engaged, when the relative rotation is blocked, the fixing member is purposely used. It is not necessary to take the operation | work which attaches the said switching member to and prevents the said relative rotation after that. Therefore, it is possible to further reduce the trouble of performing the above switching work.
[0015]
According to a fourth aspect of the present invention, an uneven portion is formed over the entire periphery of the rotating member, and the engaging portion of the switching member has a shape that engages with the uneven portion at an arbitrary position.
[0016]
In this case, since the concavo-convex portion is formed on the entire outer periphery of the rotating member, the engaging portion can be engaged with the concavo-convex portion at an arbitrary position. Therefore, the underfloor material support can be set to an arbitrary height.
[0017]
According to a fifth aspect of the present invention, the switching member is rotatably connected to the main body portion, and the engaging portion and the outer periphery of the rotating member are engaged with each other by rotating with the connecting portion as a fulcrum. An underfloor material support that is movable to a position where relative rotation is prevented and a position where the engaging portion and the outer periphery of the rotating member are not engaged, wherein the switching member is connected to the engaging portion from the fulcrum. Is an underfloor material support having a lever portion extending in a different direction, and the distance from the fulcrum to the tip of the lever is larger than the distance from the fulcrum to the engagement portion.
[0018]
In this case, since the distance from the fulcrum to the tip of the lever part is larger than the distance from the fulcrum to the engaging part, the switching member is rotated even with a small force, and the engaging part and the outer periphery of the rotating member are engaged. It is possible to switch between the mating position and the non-engaging position. Therefore, it is possible to further reduce the trouble of performing the above switching work.
[0019]
According to a sixth aspect of the present invention, the switching member reduces the diameter of the main body portion of the fixed member and presses against the rotating member, thereby preventing relative rotation between the rotating member and the main body portion. Move to the position where the relative rotation is possible by connecting the main body part and making the main body part not in contact with the rotating member by expanding the diameter of the main body part from the reduced state. Even if it is connected to the main body of the fixed member so as to be possible, the relative rotation between the fixed member and the rotating member is restricted or allowed only by moving the position of the switching member. Therefore, as in the case of claim 2, it is possible to reduce the trouble of performing the switching operation.
[0020]
According to a seventh aspect of the present invention, the switching member has an engaging portion engageable with the rotating member, and the engaging portion engages with the rotating member to prevent the relative rotation. An underfloor support that is coupled to the main body of the fixed member so that the engaging portion can be moved to a position allowing the relative rotation by being detached from the rotating member, and the relative rotation is prevented. 6. The position according to claim 3, further comprising the step of reducing the diameter of the main body portion of the fixing member and press-contacting the main body portion with the rotating member by pressing the main body portion against the rotating member. The underfloor material support according to any one of the above.
[0021]
In this case, at the position where the relative rotation is prevented, not only the engaging portion is engaged with the rotating member, but also the main body portion of the fixing member is reduced in diameter and is in pressure contact with the rotating member. . Therefore, the fixing member and the rotating member are fixed by applying a pressing force between the main body portion of the fixing member and the rotating member in addition to the engaging force between the engaging portion of the switching member and the rotating member. Therefore, the fixing between the support leg and the base member can be further stabilized in the fixed state.
[0022]

In this case, the switching lever 42 can rotate around the fulcrum shaft 424.
[0036]
Next, the procedure for adjusting the length of the underfloor material support 1 will be described with reference to FIGS. 7A and 7B show a state in which the stopper 40 is fitted so as to restrict the relative movement between the support leg 10 and the first base member 20 (second base member 30). It shows a fixed state. In this state, the switching lever 42 has the engaging portion 423 of the engaging member 421 engaged with the uneven portion 26 (uneven portion 36) of the first base member 20 (second base member 30). The relative rotation between the base member 20 (second base member 30) and the stopper 40 is locked. In addition, since the relative rotation between the stopper 40 and the support leg 10 is locked via the protrusion 416 and the sliding groove 13, the support leg 10 and the first base member 20 (second base member 30). The relative movement with is restricted.
[0037]
The procedure for adjusting the length of the underfloor material support 1 will be described below.
[0038]
Procedure 1 (see FIGS. 7 and 8): By pulling up the lever portion 422 of the switching lever 42 from the state of FIGS. 7A and 7B, the switching lever 42 is rotated about the fulcrum shaft 424. 8A and 8B, the state shown in FIG. At this time, the engaging portion 423 of the switching lever 42 moves downward along with the rotation and is disengaged from the uneven portion 26. That is, the engagement state between the engaging portion 423 and the concavo-convex portion 26 of the switching lever 42 is released, and the relative rotation between the stopper 40 and the first base member 20 (second base member 30) becomes possible. Relative rotation between the support leg 10 and the first base member 20 (second base member 30) is also possible (corresponding to a released state). Then, the supporting leg 10 and the first base member 20 (second base member 30) are relatively rotated to perform screw propulsion. In this case, the protrusion 416 of the stopper 40 moves in the axial direction along the sliding groove 13 of the support leg 10. That is, the stopper 40 and the support leg 10 move relative to each other in the axial direction. Further, the convex portion 413 of the stopper 40 and the concave portion 27 (concave portion 37) of the first base member 20 (second base member 30) can be rotated relative to each other, and relative movement in the axial direction is restricted. Since they are fitted, the stopper 40 and the first base member 20 (second base member 30) do not move relative to each other in the rotation axis direction.
[0039]
Procedure 2 (see FIG. 9): In the released state, the screw propulsion is continued until the underfloor material support 1 has a desired length. In this case, the stopper 40 and the first base member 20 (second base member 30) do not move relative to each other in the rotation axis direction regardless of the state of screw propulsion.
[0040]
Procedure 3 (see FIG. 10): By pulling down the lever portion 422 of the switching lever 42 from the state of FIG. 9, the engaging portion 423 of the switching lever 42 is again moved to the first base member 20 (second base member 30). Engage with the concavo-convex portion 26 (concavo-convex portion 36) to lock the relative rotation between the first base member 20 (second base member 30) and the stopper 40. In this case, since the stopper 40 and the support leg 10 are fitted in a state in which the relative rotation is restricted, the relative rotation between the first base member 20 (second base member 30) and the stopper 40 is locked. The screw propulsion is prevented only by doing so, and the state is switched from the open state to the fixed state.
[0041]
As described above, when the underfloor material support 1 as described above is used, in the opened state, the stopper 40 and the first base member 20 (second base member 30) are relatively rotatable, and the stopper 40 The support leg 10 is fitted in a state in which relative movement in the rotation axis direction is possible. Therefore, even when the stopper 40 is fitted to the support leg 10 and the first base member 20 (second base member 30), the screw propulsion is not hindered, and the length of the underfloor material support 1 is reduced. It is possible to adjust the height. Therefore, in such a case, it is not necessary to lift the stopper and perform the relative rotation.
[0042]
Further, when the relative rotation is performed, the stopper 40 does not move relative to the first base member 20 (second base member 30) in the rotation axis direction. Therefore, when switching to the fixed state, there is no need to bother to move the stopper 40 in the direction of the rotation axis and bring it into contact with the first base member 20.
[0043]
Furthermore, since the relative rotation of the stopper 40 and the support leg 10 is originally restricted, the relative rotation between the stopper 40 and the first base member 20 (second base member 30) is only prevented or allowed. Thus, it is possible to prevent or allow the screw propulsion. That is, it is possible to switch between the fixed state and the open state only by performing such work.
[0044]
Therefore, it is possible to reduce time and effort for adjusting and fixing the length and height of the support leg 10 and the first base member 20 (second base member 30).
[0045]
Since the switching lever 42 is connected to the stopper 40 by fitting the fulcrum shaft 424 of the switching lever 42 to the lever fitting portion 415, the switching lever 42 is not accidentally lost.
[0046]
Further, by pulling up the switching lever 42 around the fulcrum shaft 424 by pulling up the lever portion 422 of the switching lever 42, the engaging portion 423 of the switching lever 42 is moved to the first base member 20 (second base member 30). ), And the engagement can be released. Therefore, it is possible to further reduce the trouble of performing the switching operation between the released state and the fixed state.
[0047]
Furthermore, since the uneven part 26 (uneven part 36) is formed over the entire outer periphery of the first base member 20 (second base member 30), the engaging part 423 of the switching lever 42 is at an arbitrary position. It is possible to engage with the uneven portion 26 (the uneven portion 36). Therefore, the underfloor material support 1 can be set to an arbitrary height.
[0048]
Since the distance from the fulcrum shaft 424 to the tip of the lever portion 422 is larger than the distance from the fulcrum shaft 424 to the engaging portion 423, the switching lever 42 is rotated even with a small force to engage the engaging portion 423 and the uneven portion 26 (uneven portion). It is possible to switch between the position where the part 36) is engaged and the position where it is not engaged. Therefore, it is possible to further reduce the trouble of performing the above switching work.
[0049]
In the following embodiments, the same parts as those in the first embodiment are denoted by the same reference numerals, and redundant description thereof is omitted.
[0050]
Other embodiments
(1) In the present invention, in the released state, the relative rotation between the support leg 10 and the stopper 40 is restricted, and the relative rotation between the base member including the first base member 20 and the second base member 30 and the stopper 40 is performed. Alternatively, the relative rotation between the support leg 10 and the stopper 40 may be permitted, and the relative rotation between the base member and the stopper 40 may be prevented.
[0051]
Specifically, as means for enabling relative rotation between the support leg 10 and the stopper 40, the sliding groove 13 of FIG. 1 and the convex portion 416 of FIG. 4A are eliminated, and the base member and the stopper are provided. In order to prevent relative movement including relative rotation, it is conceivable that each member is provided with a dent or protrusion so that both members are fitted together, or the stopper and the base member are integrally molded. .
[0052]
Also in this case, by preventing the relative rotation between the support leg 10 and the stopper 40, the released state can be fixed, that is, the support leg 10 and the base member can be fixed. As a configuration for preventing the relative rotation between the support leg 10 and the stopper 40 in this way, for example, instead of providing the uneven portion 26 (the uneven portion 36) on the base member as in the first embodiment, the support leg It is conceivable that a similar concavo-convex portion is provided on the outer periphery of the rim 10, and the engaging portion 422 of the switching lever 42 is fitted to the concavo-convex portion.
[0053]
Even when such an underfloor material support is used, in the above open state, the stopper and the support leg can be rotated relative to each other in the direction of the rotation axis as well as in the case of the first embodiment. Similarly, even when the stopper is fitted to the support leg and the base member, screw propulsion is not hindered, and the length of the underfloor material support can be adjusted. Therefore, in such a case, it is not necessary to lift the stopper and perform the relative rotation.
[0054]
Further, when the relative rotation is performed, the stopper does not move relative to the base member in the direction of the rotation axis. Therefore, similarly to the first embodiment, when switching to the fixed state, the stopper is purposely moved in the direction of the rotation axis. There is no need to perform the operation of contacting the base member.
[0055]
Furthermore, since the relative rotation of the stopper and the base member is also restricted, the above-mentioned screw propulsion should be prevented or allowed only by preventing or allowing the relative rotation between the stopper and the support leg. Is possible. That is, it is possible to switch between the fixed state and the open state only by performing such work.
[0056]
Therefore, as in the first embodiment, it is possible to reduce time and effort for adjusting and fixing the length and height of the support leg and the base member.
[0057]
However, the member provided with the female screw portion 25 as in the first embodiment (the first (first)) than the case where the uneven portion is provided in the member provided with the male screw portion 12 such as the support leg 10 as in the present embodiment. In the embodiment, when the concave and convex portions are provided on the first base member 20 and the second base member 30), relative movement in the axial direction is prevented from the member provided with the stopper 40 and the female screw portion 25. It is more preferable because the range in which the uneven portion is provided in the axial direction is short.
[0058]
(2) Further, in the present invention, in the fixed state, the fixing of the fixing member and the rotating member is not limited to the engagement of the engaging portion of the switching member and the concavo-convex portion of the rotating member. A force due to the pressure bonding between the main body portion of the fixing member and the rotating member may also be applied to stabilize the fixing between the support leg and the base member. Specifically, the following can be considered.
[0059]
As for the lever holding portions 414 and 414 of the stopper 41 in FIG. 3A, the interval remains constant, and the thickness increases from the distal end to the proximal end. Then, after the fulcrum shaft 424 of the switching lever 42 shown in FIG. 4 is fitted to the lever fitting portion 415, when the lever portion 422 is pulled down, the outer surface of the lever holding portions 414 and 414 and the switching lever 41 are held between them. It is set as the structure which contacts the inner surface of the part 425,425.
[0060]
In such a configuration, as the switching lever 422 is pulled down, the holding portions 425 and 425 come into contact with the base end sides of the lever holding portions 414 and 414. Furthermore, since the lever holding portion 414 is thicker toward the base end, the lever holding portion 425, 425 comes into contact with the base end side of the lever holding portion 414, 414, so that the lever holding portion The interval between 414 and 414 will be narrowed. That is, as the lever portion 422 is pulled down, the diameter of the stopper 41 becomes narrower, and the support leg 10 and the first base member 20 (second base member 30) are tightened.
[0061]
Therefore, when the switching lever 422 is pulled down, the relative rotation is prevented not only by the engagement force between the engagement portion 423 and the concavo-convex portion 26 (the concavo-convex portion 36) but also by the force due to the tightening. Fixing to the base member 20 can be further stabilized.
[0062]
(3) The support leg 10 is not necessarily provided with the male screw portion 12, and the first base member 20 (second base member 30) is provided with the female screw portion 25 (female screw portion 35), the concave and convex portion 26 (uneven portion 36), and the concave portion 27 ( There is no need to provide a recess 37). For example, it is also possible to provide a female screw part, an uneven part, and a concave part on the support leg 10 and to provide a male screw part on the first base member 20 (second base member 30).
[0063]
(4) As the switching member of the present invention, a fastening jig such as a bolt or a nut may be attached between the lever fitting portions 415 and 415 instead of the switching lever 42. In this case, the interval between the lever fitting portions 415 and 415 is narrowed by tightening the tightening jig, and relative rotation between the main body portion 42 and the rotating member is prevented. Further, by loosening the tightening jig, the interval between the lever fitting portions 415 and 415 is widened to allow relative rotation between the main body portion 42 and the rotating member.
[0064]
(5) The base member of the present invention does not necessarily have to be provided at both ends of the support leg, and may be provided only on one side. For example, the support leg 10 and the first base member 20 or the support leg 10 and the second base member 30 may be integrally formed, and the base member may be integrated.
[0065]
【The invention's effect】
When the underfloor material support of the present invention is used, in the released state, relative movement in the rotation axis direction with respect to the member provided with the female screw portion is restricted, and relative to the member provided with the male screw portion in the rotation axis direction. Movement is allowed, and relative rotation with respect to any one of the member provided with the female screw portion and the member provided with the male screw portion is allowed. Therefore, even when the fixing member is fitted to the support leg and the base member, the screw propulsion is not hindered, and the length of the underfloor material support can be adjusted. Therefore, in such a case, it is not necessary to lift the stopper and perform the relative rotation.
[0066]
Further, when the relative rotation is performed, the fixing member and the member provided with the female screw portion move integrally in the rotation axis direction. Therefore, when switching to the fixed state, it is not necessary to move the fixing member in the direction of the rotation axis and bring it into contact with the member provided with the female screw portion.
[0067]
Further, relative rotation of the fixing member and a member different from the rotating member is restricted in the first place. Therefore, it is possible to prevent the screw propulsion only by preventing relative rotation between the fixing member and the rotating member, and fix the underfloor material support. That is, it is possible to switch between the fixed state and the open state only by performing such work.
[0068]
Therefore, it is possible to reduce the trouble of adjusting and fixing the length and height of the support leg and the base member.
