Description

【０００１】
【発明の属する技術分野】
本発明はプールの水深を浅くするためにプールの底に設置されるプール用床にかかり、特に泳者が床下側に潜り入ることができないようにした構造のものに関する。
【０００２】
【従来の技術】
この種プール用床は、図１９に示されているように、適宜な間隔を開けて並置されたアングル材１１０上に長尺床材１２０を並設して形成された床板１００を、上記アングル材に装着した複数の籠状の脚体１３０で支持し得るように設け、さらに、プール底に設置して水泳用に供した場合に、水中に潜った泳者、特に子供などが脚体１３０相互の空隙から床板１００の下側に入り込まないように、隣接する脚体相互間に潜り込み防止用の長尺板材１４０を架け渡して形成されている（実公平２−２７０９４号）。
【０００３】
【発明が解決しようとする課題】
従来のプール用床にあっては、床の周囲四側の脚体相互間にそれぞれ板材１４０を架け渡さねばならず、取付けに手間を要するものであった。また、上記脚体は、プール用床を解体し、各部材を保管庫などに収納し保管する場合の便宜向上のため、不使用時にコンパクトに折り畳め、小スペース内に多数積み重ねて収納し得るように構成可能であるが、脚体を折り畳み自在に設けると、上記板材１４０の脚体への取付けが簡便に行えないという問題があった。
【０００４】
そこで、本発明は上記問題点に着眼し、脚体に潜り込み防止用の板材を簡便且つ確実に取り付けることができるようにしたプール用床を提供せんとするものである。
【０００５】
【課題を解決するための手段】
上記課題を解決するため本発明のプール用床は、床板底部の少なくとも四隅に脚体を取り付けて当該床板を複数の脚体で支持するように形成されたプール用床であって、上記脚体は、床板底部に固定される枠板と、互いに先端部が凹凸係合し得るように設けられ、且つそれぞれ元端部同士が適宜な間隔を開けて枠板に回動自在に取付けられた一対の脚板とからなり、上記枠板から所定角度回動させた両脚板の先端部を凹凸係合させるとともに当該係合部をロック部材で固定し、この脚板の先端部を接地させて立設し得るように形成されているとともに、上記脚板の側部に潜り防止板受け部が設けられ、床板底部に取り付けられた前後に隣接する脚体相互の空隙を当該両脚板の上記受け部間に架け渡した潜り防止板により遮蔽し得るように構成してなるものである。
【０００６】
また、本発明のプール用床は、上記脚板の両側部に適宜な幅の張出部が突設されており、床板底部に取り付けられた左右に隣接する脚体相互の空隙が、当該左右脚体の両脚板の張出部で遮蔽されるように脚体を床板に取り付けて構成してなるものである。
この場合、張出部に潜り防止板受け部を設け、前後脚体相互の空隙を当該両脚体の張出部の上記受け部間に架け渡した潜り防止板により遮蔽し得るように構成することができる。
【０００７】
上記構成において、受け部に挿通した潜り防止用の板材を係止固定する係止手段を具備することが好ましい。係止手段は、脚板側部或いは張出部と潜り防止用の板材の何れか一方又は双方に設けることができる。
【０００９】
本発明のプール用床によれば、前後脚体相互の空隙は、脚体の受け部を介して架け渡された潜り防止用の板材により遮蔽される。
また、受け部を有する張出部を脚体の両側部に突設すれば、隣接配置した左右脚体相互の空隙は両脚体の張出部により遮蔽され、前後脚体相互の空隙は各脚体の張出部の受け部を介して架け渡された潜り防止用の板材により遮蔽され、床板の下方に子供などの泳者が潜り入る虞れはない。
この場合、床の短手方向の辺の下方空隙は、張出部により遮蔽されるので、この側に潜り防止用の板材を取付ける手間が省け、前後脚体相互間に架け渡された潜り防止用の板材は、係止手段により係止固定されているので、使用中、位置がずれたり外れたりすることがなく、当初の取付け位置に確実に保持される。
折り畳み自在の上記脚体は、床板を安定的に支持し、凹凸係合部にロック部材の突部が挿入係止してあるので、使用中に脚板が回動したり凹凸係合が分離したりせず、立設状態を確実に保持し、解体する際は、ロック部材を操作して先端部同士の係合の固定を解除した後、回動自在とした両脚板を枠板に折り重ねて小さくコンパクトに納められ、複数個を安定的に積み重ねることができる。
なお、潜り防止板受け部は、潜り防止板が挿通し得る長孔とすれば確実に保持できて好ましいが、潜り防止板が挿通可能な溝などの他の形態としてもよい。
【００１０】
【発明の実施の形態】
以下、本発明の好適な実施形態を図面により説明する。
図１〜図１０は本発明の第１実施形態を示し、図１はプール底に設置したプー用床の略外観図、図２はプール用床の要部側面図、図３はプール用床の構成要素である脚体の分解斜視図、図４はロック部材の正面図、側面図及び断面図、図５は脚板とロック部材の分解斜視図、図６は先端部を凹凸係合させた状態の脚板の要部断面図、図７は張出部を有する脚板の内面図、図８は張出部の係止部材の動作を説明するための図、図９は脚体の組み立てと折り畳みを説明するための図、図１０は潜り防止板の取付け手順を説明するための図である。
なお、図３、図６及び図９は脚体を底部側から見たときの状態を示してある。
【００１１】
本形態のプール用床１は、従来と同様、プール底面嵩上げ用の床板２、床板２を適宜高さに支持する脚体３及び脚体相互の間隙を遮蔽するための潜り防止板４からなり、脚体３を小さく折り畳める構造のものとし、さらに立設状態において脚体両側方に突出して設けた張出部で潜り防止板４を支持し得るように構成したものである。
【００１２】
床板２は、中空部を有するプラスチック製の長尺状の床材２０と、床材２０を支持する支持部材としてのアングル材２１からなり、互いに向かい合わせにして適宜な間隔離して配置したアングル材２１，２１を一組みとして、複数組みをこれと平行に互いに適宜な間隔を開けて並置し、これらアングル材２１の上にアングル材と交差する向きで複数本の床材２０を敷設すると共に、各々ボルトやリベット等の固着具（図示せず）を用いてアングル材２１に締結固定し、適宜な長さ及び幅の水平な床面に形成してある。
上記対向配置した一組みのアングル材２１，２１は、脚体３の枠板３０の長手方向の寸法と略同寸法離して配置してあり、両アングル材に脚体３を取付け、固定できるように設けてある。
床材２０とアングル材２１との連結は、上記固着具を用いる他、部材同士の嵌合や係合による固定等の適宜な連結手段により行なうことができる。
【００１３】
脚体３は、図３に示されているように、床板２の底部に固定される枠板３０と、互いに先端部同士が凹凸係合し得るように設けられ、且つそれぞれ元端部同士が適宜な間隔を開けて枠板３０に回動自在に取付けられた一対の脚板３１，３２からなり、軽量化及び腐食防止の為、それぞれプラスチックを用いて一体成形加工により形成してある。
【００１４】
さらに詳しくは、枠板３０は矩形板に中空部を設けた形状を呈し、床板２の底部に重なる頂面縁部に床材２０の底面と当接する突部３０ａを設け、その底部の四隅角部にボルトやナット等の固着具を挿通し係止可能な取付け孔３０ｂを穿設し、底部の長手方向両端辺部に両脚板の連結部と互いに軸支し合うように形成された連結部３０ｃ，３０ｄを設けて形成してある。
上記両連結部は、共に複数個の枢支用突起３３ａを枠板底部から突設し、この内、中央二つの枢支用突起間に支軸３３ｂを横設し、両端の枢支用突起３３ａには支軸が挿通し得る軸穴３３ｃを形成してなり、また、枠板３０の底面に対して連結部３０ｃが連結部３０ｄよりも高くなるように設定してある。
【００１５】
脚板３１，３２は、それぞれ周側辺を断面アーチ状に折曲した板枠状を呈し、脚板３１の先端部をアーチ状の先端凹部３１ａとし、脚板３２の先端部を櫛歯状の先端凸部３２ａとして、上記先端凹部３１ａ内に先端凸部３２ａを嵌入し係合し得るように設け（図６参照）、両脚板の元端部に枠板３０の連結部３０ｃ，３０ｄと互いに軸支し合うように形成された連結部３１ｂ，３２ｂをそれぞれ設けて形成してある。
上記両連結部は、それぞれの脚板の元端部に、嵌合溝３３ｄと被枢支用突起３３ｅとを上記枠板３０の連結部３０ｃ，３０ｄの枢支用突起３３ａと対応させて設けると共に、各被枢支用突起及び突起間に軸穴３３ｃと支軸３３ｂを上記枢支用突起３３ａの支軸及び軸穴に対応させて形成してあり、嵌合溝３３ｄ内に上記枢支突起３３ａを嵌合させ、各々支軸３３ｂを軸穴３３ｃに嵌入することにより、枢支用突起３３ａと被枢支用突起３３ｅとが支軸３３ｂにより回動可能に軸支され、両脚板が枠板３０に回動自在に取付けられるようになっている。
【００１６】
また、脚板３１の表面側において、先端中央部に凹陥部３１ｃが設けられており、この凹陥部３１ｃ内に、脚板３１，３２の先端部同士の係合を固定するロック部材３４が装着してある。ロック部材３４は、図４及び図５に示されているように、底部に係止突起３４ａ付きの取付軸部３４ｂが突設された基部３４ｃの両側に、湾曲部を介して片手で把持可能な幅離れて平行に突出する腕片３４ｄ，３４ｄを連設し、両腕片の先端部に、腕片と交差し且つ先端が基部３４ｃの側縁３４ｅよりも外方に突出する棒状突部３４ｆ，３４ｆと下方に突出する突片３４ｇ，３４ｇとを設けて形成してある。
凹陥部３１ｃ内でロック部材３４は、凹陥部の元端側底面に穿設した軸孔３１ｄに取付軸部３４ｂを圧入係止させると共に、凹陥部の先端側底面に脚板の先端縁辺と平行に穿設した開口３１ｅ，３１ｅに上記突片３４ｇ，３４ｇを、凹陥部の先端側両側面に穿設した軸孔３１ｆ，３１ｆに上記棒状突部３４ｆ，３４ｆをそれぞれ係入させて取付けられ、上記軸孔３１ｄに圧入した取付軸部３４ｂの係止突起３４ａが軸孔の内面縁部に係止して基部３４ｃを位置固定し、棒状突部３４ｆと突片３４ｇは共に先端部を軸孔３１ｆと開口３１ｅから脚板３１の内面側に突出させて保持されるが、両腕片３４ｄ，３４ｄを手で把持する等して先端同士が接近し合う方向に腕片を弾性変形させると、両腕片の先端部は突片３４ｇ，３４ｇが当接する開口３１ｅ，３１ｅに沿って湾曲し、脚板３１の内面側に突出していた上記棒状突部３４ｆが脚板３１の先端縁辺と平行に内方に移動して、その先端部を凹陥部内側まで移動させ得るように設けてある。
従って、両脚板３１，３２を係合させる際に、両腕片３４ｄ，３４ｄを把持する等して変形させ、棒状突部３４ｆ，３４ｆの先端が脚板３１の内面側に突出しないよう凹陥部内側に退避させた状態で上記両脚板の先端部同士を凹凸係合させ、その後、上記両腕片から手を離せば、両腕片３４ｄ，３４ｄは自身の弾性によって元の形状に復帰し、上記棒状突部の先端部は、図６に示されているように、上記凹陥部側面の軸孔３１ｆと、凹凸係合状態で重なり合う脚板３２の先端凸部３２ａに形成された軸孔３２ｃとに挿通し、両孔に係止して上記係合状態を固定し、両脚板３１，３２が回動することを防止し、他方、上記の如く両腕片３４ｄ，３４ｄを把持し、棒状突部３４ｆ，３４ｆの先端部を凹陥部内側に位置させれば、上記係合の固定が解除され、両脚板３１，３２は回動自在となり、凹凸係合していた先端部同士を分離することができる。
【００１７】
また、脚板３２には、図７に示されているように、その長手方向の左右両側辺の略々中間部に、当該長手方向寸法の略々１／３程度の長さ及び短手方向寸法の略々半分程度の幅を有し、脚板側辺から側方に突出するよう一体に連ねて形成した張出部３５，３５を設けてある。
両張出部３５，３５は、その元端部に潜り防止板受け部としての長孔３５ａを潜り防止板４が挿通し得る大きさで設けてあり、この長孔３５ａに隣接させて潜り防止板４を係止固定するための係止手段としての係止部材３６を張出部内面側に具備し、さらに係止部材３６の両側を開口３５ｂ，３５ｂを穿設して形成してあり、開口３５ｂ，３５ｂから係止部材３６を操作して、長孔３５ａに挿通された潜り防止板４を係止固定し得るように形成してある。すなわち、上記係止部材３６は、図７及び図８に示されているように、先端に棒状突部３６ａを有し、この棒状突部が上記長孔３５ａ内に進入し得るよう、長孔３５ａの長手方向と直交する方向（図８中矢符Ａ方向）に摺動自在に設けられており、長孔３５ａに潜り防止板４を挿通した状態で、係止部材３６の基部３６ｂを操作し、棒状突部３６ａが潜り防止板４に形成された係止孔４ｃ内に進入することにより潜り防止板４が揺動不能となり、当該張出部に固定されるようになっている。
【００１８】
また、潜り防止板４は、プラスチックを用い、子供が床板２の下側に進入できないよう、床板２の下方間隙を適宜な幅遮蔽し得る幅、及び床板２の長手方向寸法と略同じ長さを有し、図８に断面で示した如く、中央平坦部４ａの両側縁部を湾曲部４ｂとして若干弾性変形させた状態で長孔３５ａ内に略一杯に挿通し得るように形成されており、中央平坦部４ａ上には上記棒状突部３６ａが挿通し得る係止孔４ｃが長尺方向に所定の間隔で列設してある。
【００１９】
本形態の脚体３は、枠板３０の連結部３０ｃに脚板３１を、連結部３０ｄに脚板３２をそれぞれ回動自在に取付け、図９に示されているように、枠板３０内方に両脚板３１，３２を倒し、同板に折り重ねておくことができる（同図（Ａ））。脚体３を立設させるときは、両脚板３１，３２を枠板３０から起立させ（同図（Ｂ））、それぞれ適宜角度に回動して互いの先端部同士を当接させ、上記手順によって先端部を凹凸係合させると共にロック部材３４を操作し、両脚板３１，３２を回動不能に固定して行なうことができる（同図（Ｃ））。
【００２０】
なお、両脚板３１，３２は、折り畳んで積み重ねた際の安定化のため、その短手方向の寸法を枠板３０の短手方向と同寸に設定し、また、脚体３を立設させた状態で上方からの荷重に対する強度を大きくするため、図２に示す如く、枠板３０と両脚板３１，３２とがなす角（α）が略６０°となるように脚板３１，３２の長手方向の寸法が設定してある。
また、折り畳んだ状態で両脚板３１，３２が枠板３０に平行に重なりあい、枠板３０と脚板３１，３２の外側面が共に平坦な水平面となるように、枠板３０の連結部３０ｃ，３０ｄの突出高さが設定してある。
なお、図中、符号３７は、脚体３を立設した際に、プール底Ｇに接地する脚板３１の先端部外側面に貼着した滑り防止ラバーである。
【００２１】
本形態のプール用床１は、アングル材２１に床材２０を並設して床板２を形成し、また、枠板３０に脚板３１，３２を軸支して脚体３を複数個形成し、床板２に対し少なくとも四隅、さらに必要に応じ長手方向中間部に脚体３を配設し、ボルトやナット等の固着具でアングル材２１に固定すると共に、図１０に示されている如く、各々脚板３１，３２の先端部同士を凹凸係合し、且つロック部材３４を操作して上記係合を固定し、脚体３をプール底上にＶ字型に立設し（同図（Ａ））、さらに、各脚体３の側方に張り出した張出部３５に潜り防止板４を挿通し、係止部材３６を操作して各張出部に固定することにより構成することができる（同図（Ｂ））。
【００２２】
この状態で、プール用床１の短手方向の辺の下方空隙、すなわち隣接配置した左右脚体３，３相互の空隙（図１中、矢符（Ｘ）部）は、両脚体の張出部３５，３５により遮蔽され、また、プール用床１の長手方向の辺の下方空隙、すなわち前後脚体３，３，・・相互の空隙（図１中、矢符（Ｙ）部）は、各脚体の張出部３５の長孔３５ａを介して架け渡された潜り防止板４により遮蔽され、床板２の下方に子供などの泳者が潜り入る虞れはない。
【００２３】
また、プール用床１の短手方向の辺の下方空隙は、張出部３５，３５により遮蔽されるので、この側に潜り防止板４を取付ける必要がなく組み立ての手間が省け、さらに前後脚体３，３，・・相互間に架け渡された潜り防止板４は、上記係止部材３６により係止固定されているので、使用中、位置がずれたり外れたりすることがなく、当初の取付け位置に確実に保持される。
【００２４】
また、折り畳み自在に形成された脚体３は、床板２を安定的に支持し、また、凹凸係合する脚板３１，３２の先端部間にはロック部材３４の棒状突部３４ｆを挿通して固定してあるので、使用中に両脚板が回動したり凹凸係合が分離したりする虞れはなく、立設状態は確実に保持される。
上記ロック部材３４は、脚板３１の表面側に配置してあるので操作がし易い一方、凹陥部３４内に装着され、脚板３１の表面側に突出していないので、運搬中等に部材同士の衝突等によって誤操作する等の虞れがなく、折り畳んだ脚体３を積み重ねた際にも平坦性を維持することができる。
【００２５】
また、既設のプール用床１を解体するときは、床板２から取り外した脚体３を、ロック部材３４を操作して先端部同士の凹凸係合の固定を解除し、回動自在とした両脚板の係合を外して枠板３０に両脚板を折り重ねることにより、小さくコンパクトに納めることができ、而も折り畳んだ脚体３は、その上下両面、すなわち枠板３０と脚板３１，３２の何れもが平坦な水平面に維持されるので、複数個を安定的に積み重ねておくことができ、解体された床材２０やアングル材２１、潜り防止板４等と共に、少スペース内に収納し、保管することができる。
【００２６】
本形態では、張出部３５に係止部材３６を取り付けて潜り防止板４を係止固定したが、潜り防止板４を固定するための係止手段は本態様に限定されず、他の適宜な係止手段を用いることができる。
例えば図１１に示されているように、断面矩形状の潜り防止板４を用い、その一側の中央部に係止部材３８を回動自在に軸支し、一方、張出部３５の長孔３５ａを、係止部材３８を水平に回動したときにのみ潜り防止板４が挿通し得るように凸型に形成し、潜り防止板４を長孔３５ａに挿通した後、係止部材３８を略９０°回動し、その端面を張出部３５に係止させることにより、潜り防止板４が固定されるようにしてもよい。ボルトやナット等の固着具を用いてもよい。
【００２７】
本形態では、脚板３２の左右に突設した両張出部３５に長孔３５ａを設けたが、潜り防止板４を設置する側、すなわちプール用床１の側縁部となる側の張出部３５にのみ長孔３５ａを設けてもよい。
また、張出部３５の元端部に長孔３５ａを形成したが、図１２（Ａ）に示す如く、張出部３５の先端部側に形成してもよい。
さらに、潜り防止板４が設置されない側の張出部３５は、プール用床１の短手方向の辺の下方空隙を遮蔽可能な適宜な形状のものとすることができる。例えば、図１２（Ｂ），（Ｃ）に示されているように、脚板３２の側部に適宜な長さで棒状の突部を複数個並設した形態のものなどがある。
なお、図１３に示されているように、張出部３５の端縁部を床板２の側縁下方まで突出させれば、プール用床１を並設したときでも、床の下方空隙を遮蔽することができる。
【００２８】
図１４〜図１９は本発明の第２実施形態を示し、図１４は張出部の拡大外観図、図１５は係止部材とこれが挿通する張出部のスライド溝部の外観図、図１６は係止部材の動作を説明するための図、図１７及び図１８は本形態のプール用床の使用状態の要部拡大外観図及び側面図である。
【００２９】
本形態のプール用床１は、前記実施形態と同構造の脚体３を用い、脚板３２の張出部３５に形成した長孔３９に二枚の潜り防止板４を挿通し、これらを係止部材４０で一体に係止できるように構成されたものである。
【００３０】
脚板３２の張出部３５は、図１４に示されているように、その先端部に潜り防止板４を二枚重ねて挿通し得る大きさ形状に形成された受け部としての長孔３９を有し、この長孔３９に隣接させて、当該長孔と直交する方向に延びるスライド溝部４１，４１を穿設すると共に、スライド溝部４１，４１の両側にガイド壁４２，４２を突設し、このガイド壁４２，４２の先端部と元端部とに凸部４２ａを設け、さらに、ガイド壁４２，４２の両側に開口４３，４３を穿設し、上記スライド溝部４１，４１に潜り防止板４を係止固定するための係止部材４０を張出部外面側より装着して形成してある。
【００３１】
係止部材４０は、その底部にスライド溝部４１，４１に係止する係止爪片４０ａ，４０ａを有し、頂部に操作片４０ｂを突設させ、先端部に適宜長さの棒状突部４０ｃを設けて、上記ガイド壁４２，４２間に嵌装可能な大きさ形状に形成されており、上記スライド溝部４１，４１に係止爪片４０ａ，４０を係止させて、当該レールに沿って摺動移動し得るようになっている。
また、係止部材４０は、その両側に孔４０ｄ，４０ｄが穿設され、これと隣接する両側部に凸部４０ｅ，４０ｅが突設し、当該凸部が孔４０ｄ，４０ｄ側に適宜に弾性変形し得るようになっている。
【００３２】
従って、張出部３５に装着された係止部材４０は、図１６に示されているように、脚板３２の元端部側の位置にあるときは、ガイド壁４２の凸部４２ａに上記凸部４０ｅが係合して位置固定され、棒状突部４０ｃはガイド壁４２内に位置する（同図（Ａ））。
この状態から、係止部材４０の操作片４０ｂを押動すると、凸部４０ｅが僅かに内方に凹んで凸部４２ａを乗り越え、係止部材４０はスライド可能となって張出部３５の先端部側にスライド移動する。
そして、凸部４０ｅがガイド壁４２の先端部側に設けられた凸部４２ａを乗り越えたところで係止部材４０がガイド壁４２と当接し、棒状突部４０ｃは長孔３９を横切り、その先端を長孔３９を挟んで他側に設けられた挿通孔４４内に挿通させ、係止部材４０は、凸部４２ａと凸部４０ｅとが係合して当該位置に固定される（同図（Ｂ））。
棒状突部４０ｃを長孔３９から退避させるときは、上記と逆の手順により行われる。
【００３３】
本形態によれば、前記実施形態と同構造の潜り防止板４を用い、これを張出部３５の長孔３９内に二枚重ねて収納し、上記手順で係止部材４０を操作して両板の係止孔４ｃ内に棒状突部４０ｃを挿通することにより、張出部３５に固定することができる。
この場合、長孔３９内に二枚の潜り防止板４を重ねて挿通させることができるので、図１７及び図１８に示されているように、プール用床１を前後に並設したときに、一側の床の最後部の脚体３と他側の床の最前部の脚体３との間に連結用の潜り防止板４を架け渡し、両脚体で二枚の潜り防止板４を係止固定し、脚体３，３相互の空隙を遮蔽することができる。
また、上記係止部材４０は、張出部３５のガイド壁４２内で凸部同士を係合させて位置固定されるので、使用中、潜り防止板４の係止が外れ、位置がずれたり外れたりすることがなく、当初の取り付け位置に確実に保持しておくことができる。
【００３４】
なお、上記形態では、脚体を折り畳み自在に構成したが、本発明は折り畳み式の以外の脚体にも適用し得るものである。
さらに、張出部を脚体を構成する脚板に一体成形したが、張出部は脚体と別体に形成し、後付けにより、或いは取り外し自在に設けて脚体に取り付けてもよい。これらの場合、張出部の形状は、潜り防止板を挿通し、係止固定可能であれば適宜に選定可能である。
張出部を設けずに形成した脚板の側部に潜り防止板が挿通し得る長孔を設け、この長孔に潜り防止板を係止するように構成することもできる。
【００３５】
また、潜り防止板を確実に保持可能であれば、溝など長孔以外の形態で受け部を形成することができる。
なお、床板は、人が立つことができる適宜な大きさ及び構成のものを利用することができ、その底部に脚体を直に取り付けて使用してもよい。
また、上記各実施形態は、利用態様等に応じ、それぞれ組み合わせて最良の形態に構成することができるものである。
