【０００５】
上記の請求項１または２に係る本発明を実施する場合、請求項３に記載のように、前記台枠１上に着脱自在に載置された台板４を設け、当該台板４を、複数台の搬送用台車Ｃを並列させたときに隣り合う搬送用台車Ｃの台枠１間に架設可能に構成するとともに、前記棚５を、複数台の搬送用台車Ｃを並列させたときに隣り合う搬送用台車Ｃの側枠２Ａ，２Ｂ間に架設可能に構成することができる。
【０００６】
さらに、請求項４に記載の本発明の解決手段は、車輪６を備えた台枠１と、この台枠１の左右両側に立設された左右一対の側枠２Ａ，２Ｂと、この側枠２Ａ，２Ｂ間に着脱自在に架設された棚５とから成り、前記棚５は、前記両側枠２Ａ，２Ｂの棚支持枠材９ａ，９ｂと後側支柱枠材７ｂとに選択的に嵌脱自在な嵌合部１５を有する係合部材１３ａ，１３ｂを両側辺に備えたもので、前記係合部材１３ａ，１３ｂを使用して両側枠２Ａ，２Ｂの後側支柱枠材７ｂ間に背面パネル状に架設することと、前記係合部材１３ａ，１３ｂを使用して側枠２Ａ，２Ｂの棚支持枠材９ａに側面パネル状に係止することとが可能に構成され、前記台枠１上に着脱自在に載置された台板４を備え、当該台板４が、複数台の搬送用台車Ｃを並列させたときに隣り合う搬送用台車Ｃの台枠１間に架設可能に構成され、さらに前記棚５が、複数台の搬送用台車Ｃを並列させたときに隣り合う搬送用台車Ｃの側枠２Ａ，２Ｂ間に架設可能に構成するものである。また、上記の請求項３または４に係る本発明を実施する場合、請求項５に記載のように、前記棚５の左右両側辺それぞれに前後一対設けられた係合部材１３ａ，１３ｂを、前後対称位置ではなく前後何れかにずらしておき、棚５を前後正向きに架設したときと前後逆向きに架設したときとで、各係合部材１３ａ，１３ｂの位置が前後方向に離間するように構成したり、上記の請求項３〜５の何れかに係る本発明を実施する場合、請求項６に記載のように、前記台板４の四隅に、両側枠２Ａ，２Ｂの前後支柱枠材７ａ，７ｂに嵌合する凹欠部１８を設け、各凹欠部１８には、台板４の左右両側辺側から前記支柱枠材７ａ，７ｂを挟むように突出する突起部１８ａを設けることができる。更に、請求項１〜６の何れかに係る本発明を実施する場合、請求項７に記載のように、前記台枠１を、両側枠２Ａ，２Ｂ間に架設された棚５を取り外した状態において、両側枠２Ａ，２Ｂが互いに隣接する状態で水平方向にネスティング可能に構成することができる。
【０００８】
【発明の実施の形態】
以下に本発明の好適実施形態を添付図に基づいて説明すると、図１において、１は平面形状がＮ形の台枠、２Ａ，２Ｂは当該台枠１の左右両平行枠材３ａ，３ｂ上に立設された左右一対の側枠、４は台枠１上に着脱自在に載置された台板、５は両側枠２Ａ，２Ｂ間に着脱自在に架設された２段の棚である。台枠１は、左右両平行枠材３ａ，３ｂと、この左右両平行枠材３ａ，３ｂの互いに逆位置にある端部どうしを連結一体化する斜め連結枠材３ｃとから構成されたもので、その四隅下側には自在車輪６が取り付けられている。側枠２Ａ，２Ｂは、前後一対の支柱枠材７ａ，７ｂと、この前後一対の支柱枠材７ａ，７ｂの上端を互いに連結一体化する連結枠材８と、前後一対の支柱枠材７ａ，７ｂ間に架設された上下２段の棚支持枠材９ａ，９ｂとから構成されている。
【０００９】
棚５は、図２に示すように、左右方向線材１０と前後方向線材１１とを格子状に配列するとともに各交点で線材１０，１１どうしを結合一体化して成るものであるが、左右方向線材１０として、前後２本の左右方向線材１０ａ，１０ｂを棚５の左右両側辺より所定長さ突出させて、係合部材取付用の線材突出部１２を構成している。係合部材１３ａ，１３ｂは合成樹脂など（ゴムなどの弾性部材を含む）により一体成形されたもので、図３〜図６に示すように、側枠２Ａ，２Ｂの棚支持枠材９ａ，９ｂに外嵌して弾性的に挟持する一対の挟持片１４ａ，１４ｂから成る嵌合部１５と、前記線材突出部１２が嵌入する孔１６と、この孔１６に前記線材突出部１２を挿入したとき、当該線材１０ａ，１０ｂの上側に重なって固着されている棚左右両側辺構成線材１１ａ，１１ｂが嵌合する前後方向凹溝部１７とを備えている。
【００１０】
上記構成の係合部材１３ａ，１３ｂは、孔１６に棚５の線材突出部１２を、凹溝部１７に棚左右両側辺構成線材１１ａ，１１ｂが嵌合係止する位置まで圧入することにより、棚５の所定位置にワンタッチで取り付けることができる。取り付けられた係合部材１３ａ，１３ｂが線材突出部１２を中心に回転することは、棚左右両側辺構成線材１１ａ，１１ｂと凹溝部１７との嵌合により阻止される。そして、係合部材１３ａ，１３ｂが線材突出部１２から抜け落ちることは、棚左右両側辺構成線材１１ａ，１１ｂと凹溝部１７との嵌合により阻止される。勿論、孔１６と棚５の線材突出部１２、及び凹溝部１７と棚左右両側辺構成線材１１ａ，１１ｂとを接着剤で接着しても良い。
【００１１】
なお、図２に示すように、前記係合部材１３ａ，１３ｂ（線材突出部１２を有する前後２本の左右方向線材１０ａ，１０ｂ）は、前後対称位置ではなく前後何れかに（図示例では後ろ側へ）ずらしてあって、図７に実線で示すように、棚５を前後正向きに配置したときと、図７に仮想線で示すように、前後逆向きに架設したときとで、前後一対の係合部材１３ａ，１３ｂの位置が重ならないで前後方向に離間するように構成している。
【００１２】
しかして、上記のように構成された棚５は、図１Ｂ、図７、及び図８Ａに示すように、その左右両側辺に突設された各前後一対の係合部材１３ａ，１３ｂを、両側枠２Ａ，２Ｂの同一レベルにある棚支持枠材９ａ，９ｂに嵌合部１５を利用して弾性的に上から下向きに押圧外嵌させることにより、両側枠２Ａ，２Ｂ間に中間棚として水平に架設することができる。
【００１３】
また、このように棚５が架設されている状態において同一構成の予備の棚５、または両側枠２Ａ，２Ｂ間から取り外した棚５は、図１Ａの仮想線、及び図７に示すように、その両側辺の各一対の係合部材１３ａ，１３ｂを、両側枠２Ａ，２Ｂの後側支柱部材７ｂの上下２箇所に嵌合部１５を利用して弾性的に後ろ側から押圧外嵌させることにより、両側枠２Ａ，２Ｂ間に垂直な背面パネルとして架設することができる。この場合、２枚の棚５を上下２段に背面パネルとして架設することもできる。なお、各係合部材１３ａ，１３ｂは支柱部材７ｂに弾性的に外嵌係止されるので、棚５が重力で滑り落ちることはないが、下側になる係合部材１３ａまたは１３ｂを両側枠２Ａ，２Ｂの下側の棚支持枠材９ｂの後端部上にのせることにより、背面パネルとして架設された棚５の滑り落ちを完全に防止できる。
【００１４】
さらに、両側枠２Ａ，２Ｂ間から取り外した棚５は、図１Ａの仮想線、図７、及び図８Ｂに示すように、片側の係合部材１３ａ，１３ｂを、側枠２Ａまたは２Ｂの上側の棚支持枠材９ａに嵌合部１５を利用して内側から弾性的に押圧嵌合させることにより、当該側枠２Ａまたは２Ｂの内側に側面パネルとして吊り下げることができる。この場合、左右両側枠２Ａ，２Ｂ間の水平方向間隔と上下両棚支持枠材９ａ，９ｂ間の上下方向間隔とを同一に構成しておけば、棚５の左右両側辺に付設されている係合部材１３ａ，１３ｂを、側枠２Ａまたは２Ｂの上下両棚支持枠材９ａ，９ｂに嵌合係止させることができる。勿論、このように側面パネルとして係止させるための専用の棚支持枠材を側枠２Ａ，２Ｂに架設しておくことも可能である。
【００１５】
台板４は、図１０に示すように、左右両側辺が台枠１の左右両平行枠材３ａ，３ｂ上に載る矩形状の平板から成り、その四隅には、左右両側枠２Ａ，２Ｂを構成する支柱枠材７ａ，７ｂの下端部が内嵌する凹欠部１８を備えている。これら凹欠部１８は、台板４の左右両側辺側から前記支柱枠材支柱枠材７ａ，７ｂを挟むように突出する突起部１８ａを備えている。従って当該台板４は、その前後何れかを持ち上げて斜めにした状態で、前側または後ろ側の左右一対の凹欠部１８を対応する支柱枠材７ａまたは７ｂに係合させた後、台板４を水平に倒すことにより、後ろ側または前側の左右一対の凹欠部１８を対応する支柱枠材７ｂまたは７ａに係合させることができる形状となっている。１９は台板４の持ち運び用把手孔である。
【００１６】
以上のように構成された搬送用台車Ｃは、台板４を台枠１上に載置するとともに、２枚の棚５を、両側枠２Ａ，２Ｂの上側の棚支持枠材９ａ間及び下側の棚支持枠材９ｂ間に係合部材１３ａ，１３ｂを介して水平に架設して使用するものであるが、搬送用台車Ｃを商品などの搬送用や展示用などに使用しない場合は、図１Ａに示すように台板４と２段の棚５とを取り外した状態で、図９に示すように両側枠２Ａ，２Ｂがそれぞれ互いに隣接するように台枠１を互いに水平方向に嵌合させてネスティングすることができる。この場合、図８Ｂ及び図９に示すように、取り外した棚５を左右両側枠２Ａ，２Ｂの上側の棚支持枠材９ａの内側にそれぞれ側面パネル状に吊り下げた状態でネスティングすることもできるし、さらに、側面パネル状に吊り下げた棚５の内側に取り外した台板４を立てかけ、必要に応じて適当なベルトや紐により台板４と棚５及び側枠２Ａまたは２Ｂの３者を締結した状態でネスティングすることもできる。
【００１７】
なお、１台の搬送用台車Ｃを台板格納台車として、各搬送用台車Ｃから取り外した台板４を、使用時と同様に四隅の凹欠部１８を４本の支柱枠材７ａ，７ｂに嵌合させるようにして段積みすることができる。
【００１８】
搬送用台車Ｃを商品などの展示用として使用する場合、図１１に示すように、複数台の搬送用台車Ｃを、当該搬送用台車Ｃの左右一対の側枠２Ａ，２Ｂ間の間隔と同一間隔で並列させるとともに、当該搬送用台車Ｃを構成するのに使用されている台板４及び棚５と同一の連結用台板４Ｘ及び連結用棚５Ｘにより、隣接する搬送用台車Ｃどうしを互いに連結することができる。
【００１９】
この場合、連結用台板４Ｘの四隅の凹欠部１８は、図１０に示したような突起部１８ａを有する構造であるから、これら凹欠部１８と各搬送用台車Ｃの側枠２Ａ，２Ｂの支柱枠材７ａ，７ｂとの嵌合により、連結用台板４Ｘは、その両側の搬送用台車Ｃが互いに離間する方向に相対移動するのを阻止する。従って、連結用棚５Ｘを使用しなくとも、連結用台板４のみでも複数台の搬送用台車Ｃを連結して安全に使用することができる。また、当該連結用台板４Ｘの左右両側辺は、両側の搬送用台車Ｃの台板４の左右両側辺上に載ることになり、連結用台板４Ｘは、両側の搬送用台車Ｃの台板４より板厚分だけ高くなるが、若し、全ての台板４，４Ｘの表面を面一にする必要がある場合は、各搬送用台車Ｃの台板４の左右両側辺の板厚を、表面側からの切り込みにより階段状に半減させるとともに、連結用台板４Ｘの左右両側辺の板厚を、裏面側からの切り込みにより階段状に半減させておき、板厚半減部分どうしを互いに重ねるようにすれば良い。
【００２０】
また、連結用棚５Ｘは、その左右両側辺の係合部材１３ａ，１３ｂを左右両側の搬送用台車Ｃの側枠２Ａ，２Ｂにおける棚支持枠材９ａ，９ｂに係合させて架設されるが、この場合、図７に仮想線で示す連結用棚５Ｘのように、搬送用台車Ｃを構成するのに使用されている棚５を前後逆向きにして使用することにより、左右両側の搬送用台車Ｃの棚５の係合部材１３ａ，１３ｂに対し、連結用棚５Ｘの係合部材１３ａ，１３ｂを、棚支持枠材９ａ，９ｂの長さ方向に位置をずらして当該棚支持枠材９ａ，９ｂに係合させることができる。
【００２１】
図１２及び図１３は、係合部材１３ａ，１３ｂの別の実施形態を示すもので、この実施形態での係合部材１３Ａ，１３Ｂは、一端部を上下に重ねてスポット溶接などにより互いに固着して棚への取付部２０とした２枚の弾性金属板２１ａ，２１ｂから成り、当該２枚の弾性金属板２１ａ，２１ｂの遊端部を下側に折曲して、側枠２Ａ，２Ｂにおける棚支持枠材９ａ，９ｂに外嵌して弾性的に挟持する一対の挟持片２２ａ，２２ｂから成る嵌合部１５を構成したものである。棚５は、先の実施形態の棚５と同様に、左右方向線材１０と前後方向線材１１とを格子状に配列するとともに各交点で線材１０，１１どうしを結合一体化して成るものであるが、当該棚５の各係合部材取付位置には、当該棚５の左右両側辺を構成する各２本の前後方向線材１１ｃ，１１ｄ間に被取付板２３が固着架設され、当該被取付板２３の下側に前記係合部材１３ａ，１３ｂの取付部２０を重ねて、２本のリベットなどの固着具２４により固着している。
【００２２】
以上、図に基づいて説明した構成は、本発明の一実施形態に過ぎず、この構成に限定されないことは勿論である。例えば、台枠１を水平方向にネスティングできるように構成することは本発明の必須要件ではないが、仮にこのように台枠１を水平方向にネスティングできるように構成する場合、その台枠１の平面形状は、Ｎ形の他、Ｈ形、Ｕ形、Ｌ形、Ｍ形など、水平方向にネスティングできる形状であれば良い。また、棚５として、ネット状のものを例示したが、物品載置部分が木製や合成樹脂製の板体から成るものであっても良い。この場合、先に例示した合成樹脂などから一体成形された係合部材１３ａ，１３ｂを使用するときは、当該板体の左右両側辺から線材突出部１２を突設するとともに、当該係合部材１３ａ，１３ｂの前後方向凹溝部１７が嵌合し得る部分を棚左右両側縁部に形成しておけば良い。係合部材１３ａ，１３ｂの構成も、上記２つの実施形態のものに限定されない。
【００２３】
【発明の効果】
以上のように実施し得る本発明の搬送用台車によれば、台枠上の左右一対の側枠間に着脱自在に架設された棚を、両側枠の後側支柱枠材間に背面パネル状に架設したり、側枠の棚支持枠材に側面パネル状に吊り下げることが可能である。従って、台枠上に縦長のものを積載するような場合には、取り外した棚を背面パネル状に架設して使用することにより、取り外した棚の単独での格納や運搬を不要にして取り扱いを容易ならしめ得るとともに、両側枠の左右方向の曲げ強度の増強を図ることができる。
【００２４】
また、棚と同一構成の予備の棚を利用して、棚と背面パネルとを備えた搬送用台車として便利に使用することも可能になる。さらに、取り外した棚を側面パネルとして使用し得ることにより、搬送用台車の利用範囲が広まるとともに、水平方向にネスティング可能な搬送用台車である場合には、取り外した棚を一体化した状態でネスティング可能となり、取り外した棚の単独での格納や運搬を不要にして取り扱いを容易ならしめ得る。しかも、上記のように棚を使い分けるために、側枠側に棚係止のための特別なフックなどを付設する必要がなく、棚の左右両側辺に設けられた係合部材のみを利用して上記のように使い分けることができる。
【００２５】
更に、請求項１に記載の本発明の構成によれば、係合部材をワンタッチで、しかも安定良く棚の所定位置に取り付けることができる。また、請求項２に記載の本発明の構成によれば、棚の左右両側辺に付設する係合部材を２枚の弾性金属板から簡単に構成することができる。
【００２６】
請求項３や請求項４に記載の構成によれば、取り外した棚、または当該棚と同一構成の予備の棚と、取り外した台板、または当該台板と同一構成の予備の台板を利用して、複数台の搬送用台車を、隣り合う搬送用台車間も棚や台板が架設された商品陳列などのための空間として活用できる状態に連結することができる。この場合、請求項５に記載の構成によれば、同一構成の棚を前後向きを変えて架設するだけで、搬送用台車上の棚と搬送用台車間の連結用棚とを前後方向の位置を合わせて配置することができる。また、各係合部材の巾を大きくしてその支持強度を大きくしても支障なく使用できる。さらに、請求項６に記載の構成によれば、搬送用台車間に配置した連結用の台板により、隣り合う搬送用台車が互いに離間する方向に相対移動するのを防止して安全に使用することができる。
【００２７】
また、請求項７に記載の構成によれば、使用していない搬送用台車を、両側枠間に架設された棚を取り外した状態において水平方向にネスティングすることができ、格納時の占有面積を大幅に削減し得る。
