【発明が解決しようとする課題】
一方、本願の図7に示すように、4面の側板11、12、13、14と底板15とから形成された掘りごたつ9が公知であり、この掘りごたつ9は、床3に設けられた開口部にはめ込まれ、使用者は、畳5に座って、底板15に備えられた電熱ヒータ等の熱源Hで足を暖める。上記掘りごたつ9は、図7の側断面図である図8からよくわかるように、4面の側板11、12、13、14を開口部を形成する床端部31に側断面略L字形の取付け金具4で吊り下げるように固定され、通常、座卓Zを開口部の上に載置して使用される。
【0005】
また、図8からよくわかるように、底板15は、その4辺の側板11、12、13、14と当接する側端部の全長に係合用の突起部を延設し、この突起部を側板に凹設された溝部に嵌合する、いわゆる実加工が行なわれている。しかしながら、頻繁に足を出し入れし、繰り返し荷重がかかると、上記突起部に亀裂が発生し、それが底板15に及んでひび割れるという事態となるため、製品としての掘りごたつ9は、その底部をさらに複数の補強金具8で補強されている。補強金具8は、図8および補強金具8の斜視図である図9によく示されているように、上からの荷重に対して補強金具が撓んだり、曲がったりしないように、下向きの補強用リブ81を備え、補強されている。
【0006】
公知の掘りごたつ9は、上記したように、その長手方向側端に下向きに延設された2本の補強用リブ81を有する補強金具8をその底部に装着しているため、現場施工時に、製品掘りごたつの梱包を解いて仮置きした時に、この補強用リブ81が、例えば、畳や、床面を傷つけることがあり、そのため、作業者は、慎重に作業を行わなければならず、作業性が悪いという問題がある。さらに、掘りごたつ9の底部に補強用リブ81が突出しているため、梱包、積載等においても種々不都合な面がある。そこで、本発明は、上記問題点を解決して、取付け工事の際、周囲の畳や、床面を傷つけることがないように、作業性よく施工することができる掘りごたつを提供することをその課題とする。
【0007】
【課題を解決するための手段】
本発明は、上記課題を解決するために考え出されたものであって、つぎのような技術的手段を講じている。すなわち、本発明によれば、4面の側板と底板とから形成され、床下に設ける掘りごたつであって、該掘りごたつは、開口部を形成する床端部に側断面略L字形の取付け金具で吊り下げるように固定され、上記底板の4辺の側端部を上記4面の側板に凹設された溝部に嵌合するとともに、底板支持部とこの底板支持部の両端に立設された側板固定片とからなる補強金具を、上記底板とそれを嵌合して対向する側板とを挟持するように下方から取付け、上記側板固定片を上記対向する側板に固定した掘りごたつが提供される。
【0008】
このようにすることによって、底板の厚み分すべてが側板に設けられた溝部に嵌め込まれ、かつ、上記底板とそれを嵌合して対向する一対の側板とを挟持するように上記補強金具でしっかりと補強するとともに、底部に装着された補強金具に突出部分がないため、現場施工時に、掘りごたつを仮置きしても、畳や、床面を傷つけることがなく、作業性よく、工事を行うことができる。
【0009】
上記補強金具は、その底板支持部として長尺の金属プレートを用いるとともに、その長手方向側端に上向きに延設された2本の補強用リブを有することが好ましい。このようにすることによって、上方向からの荷重に対する応力が大となり、頻繁に足を出し入れし、繰り返し荷重が加えられても、底板支持部が撓んだり、曲がったりすることを防ぐ。
【0010】
上記2本の補強用リブの上端部が内側または外側に直角に折り曲げられ、補強用アングルとすることが好ましい。このように補強用リブをアングル構造とし、上方向からの荷重を面で支えることにより、荷重が分散され、頻繁に足を出し入れし、繰り返し荷重が加えられても、底板支持部が撓んだり、曲がったりすることをさらに効率的に防ぐ。
【0011】
上記補強金具が、その底板支持部として長尺の金属プレートを用いるとともに、その上面に断面が略方形の金属中空部材を載設したものであることが好ましい。このように、上方向からの荷重を面で支えることにより、荷重が分散され、頻繁に足を出し入れし、繰り返し荷重が加えられても、底板支持部が撓んだり、曲がったりすることをさらに効率的に防ぐ。
【0012】
上記補強金具を複数本用いて上記底板とそれを嵌合して対向する一対の側板を複数の個所で補強することが好ましい。このように、上方向からの荷重を複数の補強金具で分散して支えることにより、補強金具1個当りの荷重が少なくなり、頻繁に足を出し入れし、繰り返し荷重が加えられても、底板支持部が撓んだり、曲がったりすることをさらに効率的に防ぐ。
【0013】
【発明の実施の形態】
以下、本発明の好ましい実施の形態について、図面を参照して、さらに詳細に説明する。図1は、床3の下に設けられ、4面の側板11、12、13、14と底板15とから形成される掘りごたつ1が、開口部を形成する床端部31に、側断面略L字形の取付け金具4で吊り下げるように固定された状態を示す側断面図である。
