Description

【０００１】
【発明の属する技術分野】
本発明は住宅等の建築物の押入等のスペ−スに取り付けられる棚板ユニットに関する。
【０００２】
【従来の技術】
住宅等建築物の押入の収納スペ−ス内部に取り付ける棚板ユニットは、押入の高さ方向のほぼ中央に取り付ける押入中段と、押入の天袋位置に取り付ける枕棚の２種類がある。いずれにおいても、従来、押入内部の棚板ユニットは、図３の（イ）に示す根太方式のように、前框１２、後框１３、棚板１４の他に、棚板１４を支えるための複数本の根太Ｎを用意し、前框１２と後框１３に根太Ｎを嵌合させる切り込み段部を形成し、前框１２、後框１３を押入内部の柱に釘Ｊで固定し、前框１２、後框１３の前記切り込み段部に根太Ｎを載置し、上から棚板１４を前框１２、後框１３、根太Ｎに釘Ｊ等で固定する構造となっていた。
【０００３】
このような、従来の構造では、部材点数が非常に多くなり、しかも各部材の加工箇所が多く、施工に大きな手間がかかっていた。さらに狭い押入内部での細かな施工作業は大変施工しづらく、施工性に大変劣るものとなっていた。また、施工性以外に棚板１４の表面に釘打ちする構造ゆえ、長期間の使用後において、棚板１４表面の釘Ｊが浮き上がると寝具を出し入れする際に引っ掻いたり、釘Ｊに錆が発生したりすると、寝具を汚染することが多々あった。特に前框１２の上木口面の釘の浮き上がりや錆による寝具の破損や汚染問題が多々発生していた。
【０００４】
そこで、これらの問題点を改良したものとして、図３の（ロ）に示す差し込み溝方式のように、前框１２の裏面上端部に棚板１４を支える溝Ｍを長手方向に切削し棚板１４の浮上止めを形成し、該溝Ｍの上部に前框凸部１７を形成し、一方、棚板１４の前端部に切欠段部Ｇを設け、棚板突出部１９及び棚板凹部１８を形成し、前記前框１２の溝Ｍに棚板１４の前端部に形成された前記突出部１９を嵌合させる構造の押入の中段天袋棚がある。（例えば、特許文献１参照）
【特許文献１】
登録実用新案第３０５４５１８号公報（第１−３頁、第１図、第２図、第５図）
【０００５】
【発明が解決しようとする課題】
しかしながら、前記、登録実用新案第３０５４５１８号公報に記載の差し込み溝方式の構造では、図４に示すように、前框１２を柱等の構造躯体に取り付け固定した後、棚板１４の前端部分に形成した棚板突出部１９を前框１２の裏面に形成した溝Ｍ内に挿入して前框１２と棚板１４を接合させた際、前框１２の溝Ｍの上部に形成されている前框の凸部１７の端面と棚板１４の前端部に形成された切欠段部Ｇの棚板凹部１８との接点において、工場での製品加工精度や現場での施工精度によっては、ややもすれば隙間ｃが発生し、ひどい場合は施工後上から見て前框１２と棚板１４の接合箇所に発生した見苦しい隙間ｃが大きな問題点となっていた。
【０００６】
また、前框１２の裏面上端部に設けられた棚板１４を支える溝Ｍの底面に勾配が形成されていないので、溝Ｍの開口部付近の溝幅と挿入される棚板１４の突出部１９の厚み精度が極めて高くないと棚板１４の先端部の突出部１９が溝Ｍの開口部付近でつっかえてしまって、大変施工しづらいものとなっていた。すなわち、前框１２の裏面上端部の溝Ｍに棚板１４の突出部１９を差し込む際に溝Ｍ及び突出部１９の加工精度がほんの少し低くなって、前記溝Ｍの幅が突出部１９の幅よりも、ほんの少しでも小さくなると、突出部１９を溝Ｍに差し込むことができなくなる。反対に溝Ｍの幅が大きすぎると突出部１９を差し込んでも寸法的にゆるくなって、ガタツキが生じてひどい場合は、前框１２の上端面と棚板１４の前端部との接合箇所において、前框１２の上端面と棚板１４の表面に段差Ｄが発生したり、前框１２の上端面と棚板１４の前端部に隙間ｃが発生したりもする。また、棚板１４の固定力が弱くなったりして、施工精度、仕上がり的にも劣るものとなっていた。
【０００７】
本発明の目的は押入中段、枕棚として用いられる押入の棚板ユニットにおいて、施工が簡単で施工性が良く、前框と棚板の接合箇所における段差や隙間が発生せず、施工精度、施工の外観仕上がり的にも優れ、寝具の出し入れの際に前框の釘で寝具を引っ掻いたり釘の錆で汚したりする恐れのない、しかも長期耐久性にも優れた棚板ユニット及びその取付方法を提供することにある。
【０００８】
【課題を解決するための手段】
上記目的を達成するために、本発明に係る請求項１に記載の発明は、平板状の棚板と該棚板の前端部に略垂直に取り付けられる前框とからなる棚板ユニットであって、前記前框の裏面の上端角部には前框の長手方向に沿った切欠段部と該切欠段部の立ち上げ側面の下方の一部を更に長手方向に沿って切削した形状の前框厚み方向を溝深さとする嵌合溝が設けられ、該嵌合溝上部に形成された凸部の端面に、前框表面側へ傾斜する方向の勾配が形成されており、前記棚板の前端部には前記前框の嵌合溝及び凸部に対応し挿入嵌合される形状の突出部及び凹部が形成されていることを特徴とする。
【０００９】
係る構成から、前框上端部の切欠段部及び棚板前端部の切欠段部の加工精度が必ずしも高くなくて、棚板前端部の凹部端面に垂直度がでておらず、ひどい場合は前框との接合箇所において隙間が発生する方向の傾斜が生じてしまっていても、該傾斜を前框の切欠段部の凸部端面に形成された前框表面側へ傾斜する方向の勾配によって、適正に吸収することが可能となり、前框上端面と棚板前端部の接合箇所における隙間の発生を有効に防止できる。
【００１０】
また、前記前框の裏面の上端角部に形成された前記嵌合溝に前記棚板の前端部の突出部が挿入嵌合されて前框と棚板が接合される構造ゆえ、前框の上木口には釘による固着が不要となる。従って、長年使用後、釘が浮き上がって寝具の出し入れで寝具を引っ掻いたり、釘の錆で寝具を汚したりする恐れがない。
【００１１】
本発明の請求項２に記載の発明は、請求項１に記載の棚板ユニットにおいて、前記嵌合溝の底面に前框の裏面側へいくに従って下る方向の勾配が形成されていることを特徴とする。
【００１２】
係る構成から、前框の裏面上端部に設けられた棚板を支える溝底面に前框裏面側にいくに従って下る方向の勾配が形成されているので、施工性に大変優れたものとなる。すなわち、前框裏面上端部に形成された切欠段部の嵌合溝に棚板前端部に形成された切欠段部の突出部を差し込む際に、前框裏面上端部の嵌合溝及び棚板前端部の突出部の加工精度が若干悪くても、嵌合溝の底面に前框裏面側にいくに従って下る方向の勾配が設けられているので、嵌合溝の開口部の溝幅が棚板突出部の厚みよりも余裕を持たせて大きくすることが可能となり、棚板前端部の突出部を挿入嵌合し易くなり、施工が極めて簡単となり施工性が大幅に改善される。
【００１３】
また、嵌合溝の奥側の溝幅が、開口部側の溝幅よりも狭いので、棚板前端部の突出部を挿入した際に、がガタツキが生じにくい。さらに、棚板前端部の突出部を挿入した箇所の裏面側で棚板裏面と嵌合溝底面との間に生じる隙間に例えば現場で調達した適宜の材料、形状からなるスペ−サ−を嵌挿させることが可能となり、これによって、前框上端面と棚板表面に段差が発生しにくくなり、加えて前框上端面と棚板前端部との間で隙間も発生しにくくなる。さらに、棚板固定力が安定して強固になり、従って、施工精度、施工仕上がり的にも優れ、長期耐久性にも優れたものとなる。
【００１４】
本発明の請求項３に記載の発明は、請求項１又は２に記載の棚板ユニットにおいて、前記前框の凸部端面に形成された勾配及び又は前記前框の嵌合溝の底面に形成された勾配の大きさが１／２０〜５／２０の範囲であることを特徴とする。
【００１５】
係る構成から、前記前框の凸部端面の勾配及び又は前記前框の嵌合溝の底面の勾配の大きさが１／２０〜５／２０の範囲内であると、棚板前端部を前框に設けられた嵌合溝に嵌合させ嵌合箇所の棚板裏面の隙間にスペ−サ−を挿入して棚板を取り付け施工する場合において、その施工のし易さ、前框と棚板の接合箇所における隙間や段差等の施工精度、仕上がりにとって最適な範囲であり、さらには、施工後の棚板の取り付け強度、棚板の長期耐久性にとっても、最も好適な範囲である。
【００１６】
また、本発明の請求項４に記載の発明は、請求項１〜３のいずれかに記載の棚板ユニットを施工するに当たって、
１．押入スペ−スの中段又は枕棚取り付け箇所の周囲の壁下地材及び又は柱等構造躯体に前框を固着手段を用いて取り付け、
２．左右又は、左右及び奥側の構造躯体に受け桟を固着手段を用いて取り付け、
３．前記棚板の前端部に設けられた突出部と凹部を前記前框の裏面上端角部に設けられた嵌合溝と凸部に挿入嵌合させ、
４．該挿入嵌合箇所における、前記前框の嵌合溝底面と前記棚板の前端部裏面との間に生じた隙間にスペ−サ−を嵌挿させて固定し、
５．棚板を前記左右受け桟及び奥側受け桟の三方又は、左右受け桟の二方の上端部に固着手段を用いて固着する。
上記の方法で取り付けることを特徴とする。
【００１７】
係る棚板ユニット取付方法によれば、棚板を前框に取り付けたり、棚板ユニットを押し入れスペ−スに取り付ける際の施工が簡単で施工性に優れ、また、棚板ユニットの施工精度、施工の仕上がり的にも優れ、しかも長期耐久性にも優れた棚板ユニットとなる。
【００１８】
【発明の実施の形態】
以下、本発明の実施の形態の一例を図面にしたがって説明する。図１は本発明に係る棚板ユニットの実施の形態の一例を示す斜視図で取り付け施工状態を示す。図２は図１におけるＡ−Ａ線拡大断面図、図３は従来例の棚板ユニットを示す側面図で、（イ）は根太方式を示し、（ロ）は差し込み溝方式を示す。図４は従来の差し込み溝方式の施工時における前框と棚板の接合箇所での段差と隙間の説明図である。
【００１９】
図１において、本発明の棚板ユニト１の取付状態が示され、押入収納スペ−スの中段又は枕棚取り付け箇所の構造躯体である柱５のうち正面前方に位置する２本の柱に本発明の前框２が間口方向の水平度に注意して固着手段を用いて取り付けられている。固着手段としては、釘着の他、木工用接着剤による接着手段を用いることができる。木工用接着剤としてはユリア樹脂系接着剤、ユリアメラミン樹脂系接着剤、酢酸ビニル樹脂接着剤、ウレタン樹脂系接着剤等が好適に用いられる。また、前記接着剤と釘を併用して用いることもできる。これらの固着手段を用いて本発明の前框２の左右両端部が柱５に固着されている。
【００２０】
押入収納スペ−スの左右の受け桟４ａ及び奥側の受け桟４ｂが釘又は木工用接着剤、又は釘と接着剤の併用で固着されている。前框２と左右の受け桟４ａ、奥側の受け桟４ｂの水平度に十分注意することが肝要である。押入スペ−スの間口が十分に小さい時は奥側の受け桟４ｂを場合によっては省略することもできる。
【００２１】
棚板３の前端部を前框２の裏面上端部の嵌合溝に挿入嵌合させるようにし、さらに、左右受け桟４ａ、奥側受け桟４ｂの上に、釘（図示せず）又は木工用接着剤、又は釘と接着剤を併用して取り付けられている。
【００２２】
前框２、棚板３は主に木質材料からなっており、例えば、合板、パ−ティクルボ−ド、木材ムク板、ＬＶＬ、ＯＳＢ、ハ−ドボ−ド、中比重繊維板、又はこれらを積層した複合材料等が好適に用いられる。複合材料の一例としてＬＶＬの表面又は表裏両面に中比重繊維板を接着剤で張り合わせた積層体（ＬＶＳ）等も適する。もちろん木質材料以外の合成樹脂成型体であってもよい。押入中段又は枕棚としての強度耐久性、鋸で切断等の現場加工適正に優れた材料であれば、これら以外であってもよい。
【００２３】
前框２は断面形状が矩形で長尺の平板状の部材で、厚みがおよそ６〜３０ｍｍ、幅（施工後の高さ方向）がおよそ６０〜２００ｍｍ、長さ（施工後の間口方向）がおよそ４５０〜２７００ｍｍ程度の部材である。
【００２４】
図２において、前框２の裏面上端角部に長手方向に沿って切り欠いた形状の切欠段部２ａと該切欠段部２ａの立ち上げ側面の下方の一部を更にその長手方向に沿って切削した形状の、前框の厚み方向を溝深さとする嵌合溝Ｋが設けられている。
【００２５】
前記嵌合溝Ｋの底面ｂは前框２の裏面側へいくに従って下る方向の勾配が形成されている。すなわち、前框２を押入スペ−スに取り付ける状態で裏面側から見て、手前へ下る方向の勾配が形成されている。
【００２６】
また、前框２の前記嵌合溝Ｋの上部に凸部ｐが形成されている。該凸部ｐの端面は前框２の裏面から若干前框厚み方向へ引っ込んだ形状となっている。さらに、前記凸部ｐの端面は前框２の表面側へ傾斜する方向の勾配が形成されている。
【００２７】
一方、棚板３は厚みがおよそ６〜３０ｍｍ、幅（施工後の奥行方向）がおよそ９００ｍｍ前後、長さ（施工後の間口方向）がおよそ４５０〜２７００ｍｍ程度の巾広の板状である。
【００２８】
図２において、棚板３の前端部の上面角部には前記前框２の嵌合溝Ｋ及び凸部ｐに対応した形状の突出部Ｔ、凹部ｈが形成されている。図２は前框２と棚板３とを押入スペ−スに施工した際の取り付け状態を示す詳細な断面図であり、図中、前框２の裏面上端角部と棚板の前端部は互いに嵌合し合った形状で接合されている。
【００２９】
前框２の切欠段部２ａに形成された凸部ｐの端面が前框表面側へ傾斜する方向の勾配を有しており、棚板前端部に設けられた突出部Ｔを前框２の嵌合溝Ｋに挿入嵌合させた際に前框２の凸部ｐと棚板前端部の凹部ｈとが当接することになるが、この時前框２の凸部ｐの端面と棚板３の凹部ｈの端面との間で棚板３の裏面側へいくほど広がる形状の間隙ｕを設けるような形状にしておく。
【００３０】
このようにすることで、前框２の上端部２ｂ及び棚板３の表面においては、この間隙ｕがなくなり、前框２の凸部ｐの上角部と棚板３の凹部ｈの上角部はぴったり当接し、上から見て前框２と棚板３の接合箇所において、施工時の隙間ｃが解消できる。たとえ加工精度が高くなくても、棚板３の前端部の凹部ｈの端面が表面から見て隙間ｃが見える方向に傾斜して加工されたとしても、前記間隙ｕが有効に働いて程良く吸収するので、表面から見て前框２と棚板３の隙間ｃが解消できる。
【００３１】
また、前框２と棚板３の接合箇所の裏面において、前框２の嵌合溝Ｋの底面ｂに前框２の裏面側へいくに従って下る方向の勾配が形成されているので、棚板３の裏面と嵌合溝Ｋの底面ｂとの間にスペ−サ−ｓを挿入するための間隙が確保できる。この間隙にスペ−サ−ｓが嵌挿されている。該スペ−サ−ｓの材料としては、合板、ＬＶＬ、中比重繊維板、パ−ティクルボ−ド等の木質片が適しており、建築現場で発生する端材等をクサビ形状に適宜現場加工して用いることができる。また、木質片以外の合成樹脂成型体、金属材料等でクサビの機能を有するものであれば適宜用いることもできる。あらかじめ工場で製造したクサビをスペ−サ−として用いてもよい。
【００３２】
このように、前框２に形成された嵌合溝Ｋの溝幅は前記勾配のおかげで、嵌合溝Ｋの開口部付近は広がっており、一方、嵌合溝Ｋの溝の奥部は棚板３の突出部Ｔの厚みと略同じ程度の寸法に形成されている。嵌合溝Ｋの開口部付近の溝幅が広がっているので、棚板３の突出部Ｔを嵌合溝Ｋに挿入嵌合させる際に大変施工し易くなる。そして、前框２の嵌合溝Ｋの底面ｂに設けられた勾配のおかげで、棚板３の裏面との間に確保できる断面形状略三角形状の間隙にスペ−サ−ｓを嵌挿させれば、該スペ−サ−ｓがクサビ機能を発揮するので、前框２の上端部２ｂと棚板３の表面の高さが一致し前框２と棚板３との接合箇所で段差Ｄが発生しない。
【００３３】
また、押入の中段又は枕棚として用いる際に、棚板３表面を前框２の上端部２ｂと棚板３の表面を全く誤差無しで面一にするよりも約０．５ｍｍ〜１．０ｍｍ程度棚板３の表面側を低くしておく方が、棚板３の木口面の見苦しい基材部分が露出しないので、押し入れを正面から見て見苦しくなく、施工後の仕上がり外観的にも優れたものとなる。前記前框２の凸部ｐの高さ寸法と棚板３の凹部ｈの高さ寸法を加工時に調整すること及び前記スペ−サ−ｓのクサビ機能の働きで、このような適正な段差を確保することも可能になる。
【００３４】
さらに、前記スペ−サ−ｓをクサビ機能として用いるので、クサビ機能が働いて、前框２と棚板３とを接合する際にクサビの働きで接合箇所における寸法的な遊びが解消でき、前框２と棚板３がしっかりと固定され、このことによって、前框２と棚板３との接合強度が優れたものとなり長期耐久性能にも優れたものとなる。
【００３５】
また、前記前框２の凸部ｐに設けた勾配及び又は前記前框２の嵌合溝Ｋの底面ｂに設けた勾配の大きさが１／２０〜５／２０の範囲であると、棚板３の前端部を前框２に設けられた嵌合溝Ｋに嵌合させ嵌合箇所の間隙にスペ−サ−ｓを挿入して棚板３を取り付け施工する場合において、その施工のし易さ、施工精度、仕上がり、施工後の棚板３の取り付け強度、棚板３の長期耐久性にとっても最適である。
【００３６】
また、棚板３を前框２に取り付ける際に、前框２の上端部２ｂには釘Ｊを鬱必要がない。従って、施工後長期の使用の後、釘が浮き上がって寝具の出し入れの際に寝具を引っ掻いたり釘の錆で寝具を汚す心配がない。前框２以外の左右受け桟４ａ、奥側受け桟４ｂに向けて釘Ｊ等の固着着手段を用いて棚板３を取付固定する。また、木工用接着剤を釘Ｊと併用して施工することもできる。現場での作業環境等を配慮して接着剤の使用に支障がないようであれば釘Ｊ以外に接着剤を併用する方が良い。施工作業者の接着作業に対する熟練度、作業手間のかけ方等を考えて適宜決めればよい。
【００３７】
次に住宅等の押入スペ−スに押し入れ中段又は枕棚として本発明の棚板ユニット１を取付施工する作業手順を詳述する。先ず初めに、押入スペ−スの取り付け箇所の構造躯体、すなわち、木造軸組み工法の場合は四隅の柱５等の構造躯体、またツ−バイフォ−住宅の場合は構造壁体中のスタッド（縦枠）等の構造躯体に、前框２を固着手段を用いて取り付ける。固着手段はユリア樹脂接着剤、木工用酢酸ビニル樹脂接着剤等の木工用接着剤と釘Ｊ等を併用するか又は釘Ｊのみで取り付ける。
【００３８】
次に、左右又は左右と奥側の構造躯体に左右受け桟４ａ、奥側受け桟４ｂを接着剤や釘等で取り付ける。この時、前框２、左右受け桟４ａ、奥側受け桟４ｂの水平度を十分確保する。受け桟の材質は合板、パ−ティクルボ−ド、ＬＶＬ、又はこれらの複合板等が好適に用いることができる。特に前框２の材料は、例えば、ＬＶＬと中比重繊維板などとの複合板（ＬＶＳ）が強度、耐久性、コスト、化粧シ−トを貼着した際の仕上がり外観等を考えると好適である。
【００３９】
次に、棚板３の前端部に設けられた突出部Ｔと凹部ｈを前框２の裏面上端部に設けられた嵌合溝Ｋと該嵌合溝Ｋの上部に形成された凸部ｐに挿入嵌合させ、該挿入嵌合箇所の嵌合溝Ｋの底面ｂと棚板３の裏面との間にスペ−サ−ｓを打ち込むための間隙を確保する。続いて、該間隙にスペ−サ−ｓを嵌挿させて固定する。固定手段は釘又は釘と接着剤併用で良い。
【００４０】
この時、前框上端面と棚板表面に見苦しい段差がないように注意する。段差Ｄが全くないように面一にするか又は、約０．５ｍｍ〜１．０ｍｍ程度棚板３の表面側を低くしておく方が、棚板３の木口面の基材が露出しないので押し入れを正面から見て見苦しい基材が見えず、施工後の仕上がり外観的にも優れたものとなる。また、この時、前框２の上端部の凸部ｐと棚板３の前端部凹部ｈの接合箇所において隙間ｃが生じないように注意する。
【００４１】
次に、棚板３の前框２の上端部２ｂを除く三方に釘等の固着手段を用いて固着し棚板ユニット１の施工が完了する。受け桟が左右のみである場合は、左右受け桟４ａの上木口部分の二方に棚板３を釘Ｊ等の固着手段を用いて取り付ける。また、受け桟が左右及び奥側の三方向である場合は、左右受け桟４ａ、奥側受け桟４ｂの上木口部分の三方に棚板３を釘Ｊ等の固着手段を用いて取り付ける。前框２と棚板３との接合は前記嵌合溝Ｋに前記突出部Ｔを挿入嵌合させることで接合する。
【００４２】
このようにして、棚板３を前框２に接合したあと、棚板３と周囲の壁面との取り合い部分の隙間隠しのために、左右及び奥側の３方に雑巾摺ｒを釘Ｊ、接着剤又はそれらの併用等の固着手段を用いて取り付ける。雑巾摺ｒの材料としては、合板、ＬＶＬ、木材ムク、中比重繊維板等の木質材料の他、ポリスチレン樹脂等の合成樹脂成型体、ウレタン樹脂発泡体等が好適な例として挙げることができる。
【００４３】
【発明の効果】
以上のように本発明によれば、前框の裏面上端部の凸部の端面に前框表面側へ傾斜する方向の勾配を設けることで、棚板の前端部の凹部との間に棚板の裏面側へいくほど広がる形状の間隙が形成され、このことによって、前框の上端部及び棚板の表面においては、この間隙がなくなり、前框の凸部の上角部と棚板の凹部の上角部はぴったり当接し、上から見て前框と棚板の接合箇所において、施工時の隙間が解消できる。
【００４４】
また、前框に設けられた嵌合溝の底面に勾配を設けることで、嵌合溝開口部の幅を棚板前端部の突出部の厚み寸法よりも大きくするこができるので、施工性を著しく向上させることができる。また、前記嵌合溝の底面と棚板との間にスペ−サ−を嵌挿させるための間隙が確保でき、該間隙にスペ−サ−を嵌挿させて施工することで、施工性の向上と前框上端面と棚板表面の段差の発生を防止できるのみならず、棚板と前框の接合強度と接合の安定性が向上し、長期耐久性能にも優れたものとなる。

BACKGROUND OF THE INVENTION
The present invention relates to a shelf board unit that is attached to a space such as intrusion of a building such as a house.
[0002]
[Prior art]
There are two types of shelf board units that are installed in the storage space for intrusion of a building such as a house, a middle shelf that is attached to the center of the height direction of the indentation, and a pillow shelf that is attached to the top of the indentation. In any case, conventionally, the shelf unit inside the press-in is for supporting the shelf plate 14 in addition to the front rod 12, the rear rod 13, and the shelf plate 14, as in the joist system shown in FIG. A plurality of joists N are prepared, a notch step for fitting the joists N to the front and rear ridges 12 and 13 is formed, and the front and rear ridges 13 and 13 are fixed to the pillars inside the press-in with nails J, The joist N is placed on the cut step portions of the eaves 12 and the rear eaves 13, and the shelf 14 is fixed to the front eaves 12, the rear eaves 13, and the joists N from above with nails J or the like.
[0003]
In such a conventional structure, the number of members is very large, and the number of parts to be processed for each member is large. In addition, the detailed construction work inside the narrow indentation was very difficult to construct, and the workability was very inferior. In addition to the workability, the structure is such that the surface of the shelf 14 is nailed. Therefore, if the nail J on the surface of the shelf 14 rises after a long period of use, it will be scratched when the bedding is taken in and out, and the nail J will rust. In many cases, the bedding was contaminated. In particular, there have been many problems of bedding damage and contamination due to floating of nails on the upper lip of the front wing 12 and rust.
[0004]
Therefore, as an improvement of these problems, as in the insertion groove system shown in FIG. 3 (b), the groove M supporting the shelf 14 is cut in the longitudinal direction at the upper end of the back surface of the front collar 12, and the shelf 14 is formed, a front protrusion 17 is formed at the upper part of the groove M, and a notch step G is provided at the front end of the shelf 14, and the shelf protrusion 19 and the shelf recess 18 are provided. There is a middle top ledge shelf that is formed and has a structure in which the protruding portion 19 formed at the front end of the shelf 14 is fitted in the groove M of the front collar 12. (For example, see Patent Document 1)

Registered Utility Model No. 3054518 (page 1-3, FIG. 1, FIG. 2, FIG. 5)
[0005]
[Problems to be solved by the invention]
However, in the structure of the insertion groove method described in the above-mentioned registered utility model No. 3054518, as shown in FIG. 4, after fixing the front rod 12 to a structural housing such as a pillar, it is attached to the front end portion of the shelf 14. When the formed shelf board protrusion 19 is inserted into the groove M formed on the back surface of the front collar 12 and the front collar 12 and the shelf board 14 are joined, the front formed on the upper part of the groove M of the front collar 12 At the contact point between the end face of the ridge 17 and the shelf recess 18 of the notch step G formed at the front end of the shelf 14, the clearance c may be somewhat depending on the product processing accuracy at the factory and the construction accuracy at the site. In a severe case, an unsightly gap c generated at the joint between the front heel 12 and the shelf board 14 when viewed from above after construction is a serious problem.
[0006]
In addition, since no gradient is formed on the bottom surface of the groove M that supports the shelf plate 14 provided at the upper end of the back surface of the front rod 12, the groove width near the opening of the groove M and the protruding portion of the shelf plate 14 to be inserted If the thickness accuracy of 19 is not very high, the protruding portion 19 at the tip of the shelf plate 14 is replaced in the vicinity of the opening of the groove M, which makes it difficult to work. That is, when the protrusions 19 of the shelf plate 14 are inserted into the grooves M at the upper end of the back surface of the front rod 12, the processing accuracy of the grooves M and the protrusions 19 is slightly lowered, and the width of the grooves M is the width of the protrusions 19. If the width is slightly smaller than the width, the protrusion 19 cannot be inserted into the groove M. On the other hand, if the width of the groove M is too large, even if the protruding portion 19 is inserted, it becomes loose in dimension, and if the play is severe and rough, at the joint portion between the upper end surface of the front collar 12 and the front end portion of the shelf board 14, A step D may be generated between the upper end surface of the front heel 12 and the surface of the shelf board 14, or a gap c may be generated between the upper end surface of the front heel 12 and the front end portion of the shelf board 14. Moreover, the fixing force of the shelf board 14 is weakened, and the construction accuracy and finish are inferior.
[0007]

[0027]
On the other hand, the shelf board 3 is a wide plate having a thickness of about 6 to 30 mm, a width (depth direction after construction) of about 900 mm, and a length (frontage direction after construction) of about 450 to 2700 mm.
[0028]
In FIG. 2, a protruding portion T and a recessed portion h having a shape corresponding to the fitting groove K and the protruding portion p of the front collar 2 are formed at the upper surface corner of the front end portion of the shelf board 3. FIG. 2 is a detailed cross-sectional view showing a mounting state when the front heel 2 and the shelf board 3 are installed in the press-in space. In the figure, the back upper end corner portion of the front heel 2 and the front edge portion of the shelf board are They are joined in a shape that fits each other.
[0029]
The end face of the convex part p formed on the notch step portion 2a of the front ridge 2 has a gradient in a direction inclined to the front ridge surface side, and the protrusion T provided on the front end of the shelf board When the fitting groove K is inserted and fitted, the convex portion p of the front collar 2 and the concave portion h of the front end portion of the shelf plate come into contact with each other. At this time, the end surface of the convex portion p of the front collar 2 and the shelf plate The gap u is formed so as to widen toward the back surface side of the shelf board 3 between the end faces of the three recesses h.
[0030]
By doing so, the gap u is eliminated at the upper end 2b of the front heel 2 and the surface of the shelf board 3, and the upper corner of the projection p of the front heel 2 and the upper corner of the recess h of the shelf 3 The portions are in close contact with each other, and the gap c at the time of construction can be eliminated at the junction between the front heel 2 and the shelf board 3 when viewed from above. Even if the processing accuracy is not high, even if the end surface of the concave portion h at the front end portion of the shelf board 3 is inclined and processed in a direction in which the gap c can be seen when viewed from the surface, the gap u works effectively. Since it absorbs, the clearance c between the front heel 2 and the shelf 3 can be eliminated when viewed from the surface.
[0031]
In addition, since the bottom surface b of the fitting groove K of the front heel 2 is formed with a gradient in the direction of descending toward the back side of the front heel 2 on the back surface of the joint portion between the front heel 2 and the shelf 3, the shelf board A space for inserting the spacer s can be ensured between the back surface of 3 and the bottom surface b of the fitting groove K. Spacers s are inserted into the gaps. As the material of the spacer s, wood chips such as plywood, LVL, medium specific gravity fiber board, particle board, etc. are suitable. Can be used. Further, any synthetic resin molded body other than wood pieces, metal material, or the like having a wedge function can be used as appropriate. A wedge manufactured in advance in a factory may be used as a spacer.
[0032]
As described above, the groove width of the fitting groove K formed on the front flange 2 is widened near the opening of the fitting groove K due to the above gradient, while the inner part of the groove of the fitting groove K is The shelf board 3 is formed to have a dimension approximately the same as the thickness of the protruding portion T of the shelf board 3. Since the groove width in the vicinity of the opening of the fitting groove K is widened, it is very easy to perform the construction when the protruding portion T of the shelf plate 3 is inserted and fitted into the fitting groove K. Then, thanks to the gradient provided on the bottom surface b of the fitting groove K of the front collar 2, the spacer s is inserted into a gap having a substantially triangular cross section that can be secured between the rear surface of the shelf board 3. Then, since the spacer s exhibits a wedge function, the height of the upper end portion 2b of the front heel 2 and the surface of the shelf board 3 coincide with each other, and a step D is formed at the joint portion between the front heel 2 and the shelf board 3. Does not occur.
[0033]
Further, when used as a middle stage or a pillow shelf, the surface of the shelf board 3 is about 0.5 mm to 1.0 mm than when the upper end 2b of the front heel 2 and the surface of the shelf board 3 are flush with each other without any error. If the surface side of the shelf board 3 is kept low, the unsightly base material portion of the shelf edge of the shelf board 3 is not exposed, so that it is not unsightly seen from the front, and the finished appearance after construction is excellent. It will be a thing. By adjusting the height dimension of the convex part p of the front heel 2 and the height dimension of the concave part h of the shelf 3 at the time of processing and the function of the wedge function of the spacer s, such an appropriate level difference is achieved. It can also be secured.
[0034]
Furthermore, since the spacer s is used as a wedge function, the wedge function works, and when joining the front heel 2 and the shelf board 3, the dimensional play at the joining portion can be eliminated by the action of the wedge. The heel 2 and the shelf board 3 are firmly fixed, and as a result, the joining strength between the front heel 2 and the shelf board 3 is excellent, and the long-term durability performance is also excellent.
[0035]
Further, when the gradient provided on the convex portion p of the front heel 2 and / or the gradient provided on the bottom surface b of the fitting groove K of the front heel 2 is in the range of 1/20 to 5/20, When the shelf 3 is attached and installed by fitting the front end portion of the plate 3 into the fitting groove K provided on the front end 2 and inserting the spacer s into the gap between the fitting locations, the construction is performed. It is also optimal for ease, construction accuracy, finish, mounting strength of the shelf board 3 after construction, and long-term durability of the shelf board 3.
[0036]
Further, when attaching the shelf board 3 to the front heel 2, it is not necessary to put the nail J on the upper end 2 b of the front heel 2. Therefore, after a long period of use after construction, there is no concern that the nail will float up and scratch the bedding when putting in or out the bedding or that the bedding will be soiled by the rust of the nail. The shelf plate 3 is attached and fixed to the left and right receiving bars 4a and the rear side receiving bar 4b other than the front rod 2 by using fixing means such as a nail J. Moreover, it can also construct by using the adhesive for woodworking together with the nail J. In consideration of the work environment at the site, it is better to use an adhesive in addition to the nail J if there is no hindrance to the use of the adhesive.
