【発明の属する技術分野】
本発明は、天井材等を吊設するのに使用される吊り金具の吊り元金具に取り付けて、吊りボルトの向きを変更できるようにするための吊り金具用変向金具に関する。
【０００２】
【従来の技術】
図９及び図１０において、１は吊り元金具、２は吊り元金具１に取り付けて使用される従来の変向金具、また３は吊りボルト３である。これら吊り元金具１と変向金具２と吊りボルト３とによって吊り金具４を構成する。吊り元金具１は、側面視コ字状の金具本体５を有し、この金具本体５に締付ボルト６が取り付けられる。変向金具２は、図１０から分かるように、一対の側板部７ａ，７ａと両側板部７ａ，７ａをつなぐ連結板部７ｂとからなるコ字状本体７を有し、この連結板部４ｂには両側板部７ａ，７ａにわたってスライド溝７ｃが形成されている。しかして、変向金具２のコ字状本体７を吊り元金具１の金具本体５の一端部に嵌め込んでボルト８で枢着することによって、このボルト８を中心に変向金具２のコ字状本体６と吊り元金具１の金具本体５とが互いに回転可能となる。
【０００３】
上記のように吊り元金具１と変向金具２と吊りボルト３とからなる吊り金具４の使用にあたって、図９及び図１０に示すように、吊り元金具１の金具本体５を例えばＬ形鋼からなる上部屋根枠Ｆ１に取り付け固定した後、変向金具２のコ字状本体７に形成されたスライド溝７ｃに吊りボルト３の一端部を挿通すると共に、このスライド溝７ｃを挟むように一対の吊りボルト固定用ナット９，９を吊りボルト３に螺合しておくことにより、変向金具２は吊り元金具１に対し一定の平面に沿って所要角度α範囲内で揺動可能となり、吊りボルト３は変向金具２の揺動方向に対し直交する方向に所要角度β範囲内で揺動可能となる。尚、図９では、変向金具２から下方へ延びた吊りボルト３の先端部は、他の吊り金具から垂下して下部屋根枠Ｆ１に連結された他の吊りボルト３の下端部に取付金具Ｇを介して取り付けてある。
【０００４】
【発明が解決しようとする課題】
従来の変向金具２は、吊り元金具１に対し一定平面に沿った方向に揺動させることしかができないため、吊りボルト３の向きを任意方向に設定して吊りボルト３を固定するのに手間がかかり、作業が面倒となっていた。そこで、本発明は、吊り元金具に対し一定平面上で３６０°自由に回転させることを可能とした吊り金具用変向金具を提供し、もって吊りボルトの向きを任意方向に迅速容易に変更設定できるようにすることを目的とする。
【０００５】
請求項１に係る発明に吊り金具用変向金具は、吊り元金具１，１′に取り付けて、吊りボルト３の向きを変更できるようにするための吊り金具用変向金具１２であって、上板部１３と両側板部１４，１４とで下向きコ字枠状に形成されると共に両側板部１４，１４の下端部が下向き凸形の円弧状底板部１５でつながれ、該円弧状底板部１５の両端間の幅Ｗａは、前記両側板部１４，１４間の幅Ｗｂよりも広くなるよう形成されてなる変向金具本体１２ｏからなり、前記変向金具本体１２ｏには上板部１３に吊り元金具１，１′とボルト結合するためのボルト挿通孔１７を設け、円弧状底板部１５にはその円周方向に長く延びるボルト挿通用長孔２０を形成し、この長孔２０に吊りボルト３の一端部を挿通すると共に、この長孔２０を挟むように一対の吊りボルト固定用ナット９，９を吊りボルト３に螺合して、吊りボルト３の一端部を長孔２０の所要位置で固定するようにしたことを特徴とする。
【０００６】
請求項２は、請求項１に記載の吊り金具用変向金具において、前記変向金具本体１２ｏには両側板部１４，１４の対向位置に、吊り元金具１とボルト１８結合するためのボルト挿通孔１９を設けてなることを特徴とする。
【０００７】
請求項３は、請求項１又は２に記載の吊り金具用変向金具において、前記ボルト挿通用長孔２０は、円弧状底板部１５の円周方向長さの中間部から当該底板部１５の一端部側に亘って形成されてなることを特徴とする。
【０００８】
【発明の実施の形態】
図１は本発明に係る吊り金具用変向金具１２の外観斜視図、図２の（Ａ）は図１のＡ−Ａ線断面図、（Ｂ）は同変向金具１２を図１に示す矢印Ｂの方向から見た側面図、図３及び図４は同変向金具１２の使用形態を示す斜視図である。これらの図から分かるように、本発明に係る変向金具１２は、上板部１３と両側板部１４，１４とで下向きコ字枠状に形成されると共に両側板部１４，１４の下端部どうしが下向き凸形の円弧状底板部１５でつながれてなる変向金具本体１２ｏからなるもので、変向金具本体１２ｏの上板部１３には、図３に示すようにボルト１６を使用して吊り元金具１とボルト結合するためのボルト挿通孔１７が設けられ、各側板部１４には、図４に示すようにボルト１８を使用して吊り元金具１とボルト結合するためのボルト挿通孔１９が上下２箇所に設けられ、そして円弧状底板部１５にはその円周方向に長く延びるボルト挿通用長孔２０が形成されている。
【０００９】
変向金具本体１２ｏの円弧状底板部１５は、図２の（Ａ）から分かるように、正面視略半円状に形成されていて、その両端間の幅Ｗａは、両側板部１４，１４間の幅Ｗｂよりも広くなるように形成されており、これによりボルト挿通用長孔２０の長さをより長く形成できて、吊りボルト３の変向角度範囲を極力広くすることができる。また、ボルト挿通用長孔２０がこの円弧状底板部１５の円周方向に沿って形成されているため、吊りボルト３を円滑に揺動させることができる。また、このボルト挿通用長孔２０は、同じく図２の（Ａ）から分かるように、円弧状底板部１５の円周方向全域ではなく、その円周方向長さの略中間部から当該底板部１５の一端部側に亘って概ね９０°程度の角度範囲に形成されている。これは、円弧状底板部１５の円周方向全域に亘って長孔２０を形成すると、底板部１５の強度が低下することになり、また後記のように変向金具本体１２ｏを吊り元金具１に対し３６０°回転させることができるので、長孔２０を円周方向全域に亘って形成しなくても、吊りボルト３の変向角度範囲を狭めることがないからである。尚、このボルト挿通用長孔２０では、図５に示すように吊りボルト３を約６０°の角度範囲で揺動させることができる。
【００１０】
この変向金具本体１２ｏを製作するには、所要幅と長さを有する帯状の鋼板をプレス加工して、中間部に円弧状底板部１５を形成し、その両側に両側板部１４，１４を形成した後、両端部を折曲重合して、図示のような上板部１３を形成すればよい。尚、ボルト挿通孔１７，１９及びボルト挿通用長孔２０は、上記の成形加工をする前に予め穿孔しておけばよい。
【００１１】
上記のような構成よりなる変向金具１２を吊り元金具１に取り付けて、吊りボルト３の向きを自由に変更できる吊り金具として使用する方法について、以下に説明する。
【００１２】
図３及び図４に示される吊り元金具１は、図９及び図１０に示したものと同じ周知構造の吊り元金具で、上横枠２１と、下横枠２２と、上下両横枠２１，２２をつなぐ縦枠２３とからなる側面視コ字状の金具本体５を有する。この金具本体５の上横枠２１は両側一対の横枠部材２１ａ，２１ａからなり、下横枠２２は断面コ字状に形成され、縦枠２３は両側一対の縦枠部材２３ａ，２３ａからなり、上横枠２１の各横枠部材２１ａにはボルト挿通孔２４が形成されると共に、支持板２５が垂直に突設され、また下横枠２２には複数のボルト孔２６が形成されており、そのボルト孔２６の一つに締付ボルト６が螺入される。
【００１３】
先ず、図３に示す使用形態にあっては、本発明に係る変向金具１２の変向金具本体１２ｏの上板部１３を、吊り元金具１の金具本体５の下横枠２２の一端部下面に当接し、上板部１３のボルト挿通孔１７から下横枠２２のボルト孔２６にボルト１６を螺入して軽く締めておき、また変向金具本体１２ｏのボルト挿通用長孔２０に吊りボルト３の一端部を挿通すると共に、この長孔２０を挟むように一対の吊りボルト固定用ナット９，９を吊りボルト３に螺合して軽く締めておく。こうして本発明に係る変向金具１２を吊り元金具１に取り付けることによって、吊り金具４を組み立てる。
【００１４】
図５は、上記のようにして組み立てた吊り金具４の使用例を示したもので、吊り元金具１の金具本体５を、例えばＬ形鋼からなる若干傾転した上部屋根枠２７の所定箇所でそのウエブ２７ａに嵌め込んで締付ボルト６によって締め付け固定した後、一端部が変向金具１２に取り付けられた吊りボルト３の向きを、当該吊りボルト３の他端部が取り付けられる箇所、例えば下部屋根枠（図示省略）の所定箇所に対向するように設定する。
【００１５】
この吊りボルト３の向きの設定にあたっては、変向金具本体１２ｏが吊り元金具１に対してボルト１６の周りに３６０°回転可能であると共に、吊りボルト３が変向金具本体１２ｏのボルト挿通用長孔２０に沿って約６０°の角度範囲内で揺動できるようになっているから、変向金具本体１２ｏをボルト１６の周りで回転させながら、吊りボルト３をボルト挿通用長孔２０に沿って揺動させることによって、吊りボルト３の向きを、当該吊りボルト３の他端部が取り付けられる箇所に合致する方向に迅速容易に設定することができる。
【００１６】
尚、図５においては、実線で示す吊りボルト３は、変向金具本体１２ｏのボルト挿通用長孔２０に沿って紙面と直交する方向に揺動できる状態を示している。しかして、変向金具本体１２ｏをこの図の実線図示位置から吊り元金具１に対しボルト１６を中心に９０°回転させると、吊りボルト３は、図５の実線図示位置から同図の例えば右側に仮想線で示す位置までの約６０°の範囲内でボルト挿通用長孔２０に沿って揺動可能であり、更にその状態から変向金具本体１２ｏを１８０°反転させることによって、吊りボルト３は、図５の実線図示位置から同図の左側に仮想線で示す位置までの約６０°の範囲内でボルト挿通用長孔２０に沿って揺動可能となる。
【００１７】
上記のようにして吊りボルト３の向きを所定方向に設定したならば、変向金具本体１２ｏを吊り元金具１に取り付けているボルト１６を締め付け固定し、またボルト挿通用長孔２０を挟むように吊りボルト３に螺合している吊りボルト固定用ナット９，９の一方を他方に対し強く締め付けて、吊りボルト３を変向金具本体１２ｏに固定すればよい。
【００１８】
図４は他の使用形態を示したもので、変向金具１２及び吊り元金具１は、図３に示すものと夫々同じものである。即ち、この図４に示す使用形態においては、吊り元金具１を逆さにした状態で、変向金具本体１２ｏの上部側を吊り元金具１の金具本体５の縦枠部材２３ａ，２３ａ間に挿入し、金具本体５のボルト挿通孔２４から変向金具本体１２ｏの側板部１４に設けてあるボルト挿通孔１９に亘ってボルト１８を挿通し、その先端部にナット（図示せず）を螺合して、軽く締め付けておく。また図３の場合と同様に、変向金具本体１２ｏのボルト挿通用長孔２０に吊りボルト３の一端部を挿通すると共に、この長孔２０を挟むように一対の吊りボルト固定用ナット９，９を吊りボルト３に螺合して軽く締め付けおく。こうして変向金具１２を吊り元金具１に取り付けることにより、吊り吊り金具４を組み立てる。
【００１９】
図６は図４のようにして組み立てた吊り金具１の使用例を示したもので、吊り元金具１の金具本体５を、図４と同様に若干傾転した上部屋根枠２７の所定箇所でそのウエブ２７ａに嵌め込んで締付ボルト６によって締め付け固定した後、一端部が変向金具１２に取り付けられた吊りボルト３の向きを、当該吊りボルト３の他端部が取り付けられる箇所、例えば下部屋根枠の所定箇所に対向するように設定する。この使用例において、変向金具本体１２ｏは、吊り元金具１に対しボルト１８を中心に例えば約１６０°の角度範囲内で揺動可能であり、また吊りボルト３は、図６に実線で示す状態から、変向金具本体１２ｏのボルト挿通用長孔２０に沿って紙面と直交する方向に約６０°の角度範囲内で揺動可能である。
【００２０】
図７は、上述した吊り元金具１と変向金具１２とからなる吊り金具４の吊り元金具１を、Ｈ形鋼からなる屋根枠２８の下部フランジ２８ａ及び上部フランジ２８ｂに夫々取り付けて使用する例を示したものである。吊り元金具１を屋根枠２８の下部フランジ２８ａに取り付けた吊り金具４は、図５に示される吊り金具４の使用例と同じである。この場合、変向金具１２の変向金具本体１２ｏから延びる吊りボルト３は、実線で示す位置を仮に基準位置とすれば、この基準位置の周りに３６０°回転可能であると共に、その基準位置から放射方向へ仮想線図示のような位置まで揺動可能である。従って、一端部を変向金具本体１２ｏに取り付けた吊りボルト３の他端部を、図示のような位置にある取付枠２９，３０，３１に対し容易に取り付けることができる。
【００２１】
また、吊り元金具１をＨ形鋼からなる屋根枠２８の上部フランジ２８ｂに取り付けた吊り金具４は、図６に示される吊り金具４の使用例とは、上下の向きが逆となっているだけで、その取付方法は図６の場合と同じであって、一端部を変向金具本体１２ｏに取り付けた吊りボルト３の他端部を、例えば図示のような位置にある取付枠３２，３３，３４に対し容易に取り付けることができる。
【００２２】
図８の（Ａ）及び（Ｂ）は、変向金具１２を前記吊り元金具１とは異なった別の吊り元金具１′に取り付けて使用する使用例を示す。この吊り元金具１′は、天井下面を波板状のデッキプレート４３で形成した天井部４４に取り付けられる周知構造のもので、ボルト孔３５ａを有する底部３５の左右両端に比較的急な傾斜角度で斜め上方へ対称状に延びる支持アーム３６，３６を連設してなる略Ｖ字状の金具本体３７と、断面下向きコ字形の嵌合部３８の左右両端に比較的緩い傾斜角度で斜め上方へ対称状に延びる支持アーム３９，３９を連設して、金具本体３７の上側に配置される略Ｖ字状の突っ張り部材４０と、金具本体３７の底部３５のボルト孔３４に螺入されて、上端部が突っ張り部材４０の嵌合部３８に下方から嵌合される吊りボルト４１と、からなるもので、金具本体３７の各支持アーム３６の先端折り返し部３６ａが突っ張り部材４０の各支持アーム３９先端係止部３９ａに係嵌されている。
【００２３】
上記の吊り元金具１′に変向金具１２を取り付けるには、変向金具本体１２ｏの上板部１３に設けてあるボルト挿通孔１７（図１その他を参照）に吊り元金具１′の吊りボルト４１の下端部を挿入すると共に、このボルト４１に螺合した上下の一対のナット４２，４２で固定すればよい。しかして、吊り元金具１′を天井部４４に取り付けるときは、突っ張り部材４０の各支持アーム３９の先端係止部３９ａに係嵌した金具本体３７の各先端折り返し部３６ａを、図５の（Ｂ）に示すように天井部４４の凹部４５の係合溝４５ａに係合させた後、吊りボルト４１を回して、金具本体３７を押し上げながら突っ張り部材４０を左右方向に突っ張らせると、突っ張り部材４０の支持アーム３９の先端係止部３９ａに係嵌した金具本体３７の各先端折り返し部３６ａが係合溝４５ａに圧接して、金具本体３６を天井部４４に固定させることができる。変向金具１２の使用方法については、図３、図５及び図７で説明した通りである。
【００２４】
以上の実施形態では、変向金具本体１２ｏの側板部１４にボルト挿通孔１９を設けることによって、図４及び図６に示すような使用方法ができるようにしたことを説明したが、この使用は必ずしも必要ではなく、従って側板部１４にはボルト挿通孔１９を設けなくてもよい。この変向金具１２の大きな特徴は、変向金具本体１２ｏの上板部１３にボルト挿通孔１７を設け、このボルト挿通孔１７を介して吊り元金具１，１′とボルト１６結合することにより、変向金具本体１２ｏを吊り元金具１の金具本体５に対しボルト１６を中心に３６０°自由に回転させることができるようにしたことである。
【００２５】
【発明の効果】
請求項１に係る発明の変向金具によれば、変向金具本体が吊り元金具に対して変向金具本体取付用ボルトの周りに３６０°回転可能であると共に、吊りボルトが変向金具本体のボルト挿通用長孔に沿って所要角度範囲揺動可能となっているから、変向金具本体をボルトの周りで回転させながら、吊りボルトをボルト挿通用長孔に沿って揺動させることによって、吊りボルトの向きを、当該吊りボルトの他端部が取り付けられる箇所に合致する方向に迅速且つ容易に設定することができる。また、ボルト挿通用長孔を変向金具本体の円弧状底板部にその円周方向に沿って形成しているから、変向金具本体に対する吊りボルトの揺動を円滑に行わせることができる。
また本発明によれば、変向金具本体の円弧状底板部は、正面視略半円状に形成されていて、その両端間の幅は、両側板部間の幅よりも広くなるように形成されており、これによりボルト挿通用長孔の長さをより長く形成できて、吊りボルトの変向角度範囲を極力広くすることができる。
【００２６】
請求項２に係る発明の変向金具によれば、変向金具本体には両側板部の対向位置に、吊り元金具とボルト結合するためのボルト挿通孔を設けているから、このボルト挿通孔を利用して、吊り元金具をボルト結合することにより、変向金具本体を吊り元金具に対して上記ボルト結合するボルトを中心に所要角度範囲揺動させることができる。
【００２７】
請求項３に係る発明の変向金具によれば、ボルト挿通用長孔は、円弧状底板部の円周方向長さの中間部から当該底板部の一端部側に亘って形成されているから、底板部の強度が低下せず、変向金具本体そのものが頑強なものとなる。

It is characterized in that it is formed over one end.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is an external perspective view of a diverting metal fitting 12 for a hanging metal according to the present invention, FIG. 2A is a cross-sectional view taken along line AA of FIG. 1, and FIG. FIGS. 3 and 4 are side views as viewed from the direction of arrow B, and are perspective views showing a usage form of the turning metal fitting 12. As can be seen from these figures, the turning metal fitting 12 according to the present invention is formed in a downward U-shaped frame by the upper plate portion 13 and the both side plate portions 14 and 14 and the lower end portions of the both side plate portions 14 and 14. As shown in FIG. 3, bolts 16 are used for the upper plate portion 13 of the turning metal body 12o, which are connected to each other by an arc-shaped bottom plate portion 15 having a downwardly convex shape. A bolt insertion hole 17 for bolt connection with the suspension base 1 is provided, and a bolt insertion hole for bolt connection with the suspension base 1 using a bolt 18 as shown in FIG. Numerals 19 are provided at two upper and lower portions, and the arc-shaped bottom plate portion 15 is formed with a bolt insertion elongated hole 20 extending in the circumferential direction thereof.
[0009]
As can be seen from FIG. 2A, the arc-shaped bottom plate portion 15 of the deflection fitting main body 12o is formed in a substantially semicircular shape when viewed from the front, and the width Wa between both ends is equal to the width of both side plate portions 14, 14. It is formed so as to be wider than the width Wb between them, whereby the length of the bolt insertion slot 20 can be made longer, and the deflection angle range of the suspension bolt 3 can be made as wide as possible. Further, since the bolt insertion slot 20 is formed along the circumferential direction of the arc-shaped bottom plate portion 15, the suspension bolt 3 can be smoothly swung. Also, as can be seen from FIG. 2 (A), the bolt insertion slot 20 is not formed in the whole area in the circumferential direction of the arc-shaped bottom plate portion 15 but in a substantially middle portion of the length in the circumferential direction. 15 is formed in an angle range of about 90 ° over one end side. This is because, when the elongated hole 20 is formed over the entire area of the arc-shaped bottom plate portion 15 in the circumferential direction, the strength of the bottom plate portion 15 is reduced, and the turning metal body 12o is suspended from the original metal fitting 1 as described later. This is because the angle of rotation of the suspension bolt 3 is not narrowed even if the elongated hole 20 is not formed in the entire circumferential direction. In the bolt insertion slot 20, the suspension bolt 3 can be swung in an angle range of about 60 ° as shown in FIG.
[0010]
In order to manufacture the turning metal body 12o, a strip-shaped steel plate having a required width and length is pressed to form an arc-shaped bottom plate portion 15 at an intermediate portion, and both side plate portions 14 and 14 are formed on both sides thereof. After the formation, both ends may be bent and overlapped to form the upper plate 13 as shown in the figure. The bolt insertion holes 17 and 19 and the bolt insertion slot 20 may be pre-drilled before performing the above-described forming process.
[0011]
A method of attaching the deflection metal fitting 12 having the above configuration to the hanging metal fitting 1 and using the hanging metal fitting 3 as a hanging metal fitting that can freely change the direction of the hanging bolt 3 will be described below.
