Description

【０００１】
【発明の属する技術分野】
本発明は配線用ボックスに係り、詳しくは、固定棒に装着して間仕切り壁や二重天井などの空間の所定位置に配設されるアウトレットボックスやスイッチボックスなどの配線用ボックスに関する。
【０００２】
【従来の技術】
従来、図１６および図１７に示すように、前面に開口１０を有する配線用ボックス本体１の後部側壁１１の後面に、上下方向に所定の間隔を有して上側の横向き固定棒２Ａと下側の横向き固定棒２Ｂを装着し、これら上側の横向き固定棒２Ａと下側の横向き固定棒２Ｂを、前壁３Ａと後壁３Ｂとを備えた間仕切り壁３の空間４に立設した間仕切り用の柱体５，５に架設することで、間仕切り壁３の空間４の所定位置に配線用ボックス本体１を配設する技術が知られている。
【０００３】
ところが、従来は、配線用ボックス本体１を確実に取付けるためには、上側の横向き固定棒２Ａと下側の横向き固定棒２Ｂを間仕切り用の柱体５，５に架設する前に、配線用ボックス本体１の後部側壁１１の後面に上側の横向き固定棒２Ａと下側の横向き固定棒２Ｂを挿通装着させ、その上で上側の横向き固定棒２Ａと下側の横向き固定棒２Ｂの両端部を柱体５，５に取付ける必要があった。
【０００４】
【発明が解決しようとする課題】
しかし、上側の横向き固定棒２Ａと下側の横向き固定棒２Ｂの両端部を柱体５，５に取付けてしまった後に、配線用ボックスを上側の横向き固定棒２Ａと下側の横向き固定棒２Ｂに増設もしくは新規に装着しなければならないことがある。この増設もしくは新規の装着のときに、後壁３Ｂのみが柱体５に取付けられてしまっている場合もあれば、前壁３Ａと後壁３Ｂが柱体５に取付けられてしまっている場合もある。このようなときには、前壁３Ａのみならず作業スペース確保のため後壁３Ｂも取り外し、さらに上側の横向き固定棒２Ａと下側の横向き固定棒２Ｂの両端部を柱体５，５から取り外した上でないと配線用ボックスを増設もしくは新規に装着することができなかった。
【０００５】
そこで、本発明は、上下方向に所定の間隔を有して架設されている上側の横向き固定棒と下側の横向き固定棒もしくは左右方向に所定の間隔を有して立設されている左右両側の立上がり固定棒に対して前側から配線用ボックス本体を容易かつ確実にさらに強固に装着することができる配線用ボックスを提供することを目的としている。
【０００６】
【課題を解決するための手段】
前記目的を達成するため、請求項１記載の発明は、前面に開口を有する配線用ボックス本体の上部に上側の横向き固定棒を受け入れて前記配線用ボックスの上方および前後方向の移動を拘束する第１凹手段を、前記配線用ボックス本体の下部には下側の横向き固定棒を受け入れて前記配線用ボックスの下方および前後方向の移動を拘束する第２凹手段をそれぞれ形成し、前記第１凹手段に拘束された上側の横向き固定棒を上方より押圧する弾性変形可能な上アーム片の基部を前記配線用ボックス本体の第１凹手段より前方側の上部側壁に、前記第２凹手段に拘束された下側の横向き固定棒を下方より押圧する弾性変形可能な下アーム片の基部を前記配線用ボックス本体の第２凹手段より前方側の下部側壁にそれぞれ設け、前記上アーム片の先端側には該先端を前記上側の横向き固定棒に前方より押し込んだときに上アーム片を上方に弾性変形させて前記上側の横向き固定棒を前記第１凹手段に入れるように誘導する誘導面が形成されているとともに、前記下アーム片の先端側にも該先端を前記下側の横向き固定棒に前方より押し込んだときに下アーム片を下方に弾性変形させて前記下側の横向き固定棒を前記第２凹手段に入れるように誘導する誘導面が形成されていることを特徴としている。

【０００８】
そして、請求項３記載の発明は、前記第１凹手段が凹溝よりなりこれが前記配線用ボックス本体の後部側壁上方延長線上の上部側壁外面に形成されているとともに、第２凹手段が凹溝よりなりこれが前記配線用ボックス本体の後部側壁下方延長線上の下部側壁外面に形成されていることを特徴としている。
【０００９】
さらに、請求項４記載の発明は、前記第１凹手段が凹溝よりなりこれが前記配線用ボックス本体の後部側壁左方延長線上の左部側壁外面に形成されているとともに、第２凹手段が凹溝よりなりこれが前記配線用ボックス本体の後部側壁右方延長線上の右部側壁外面に形成されていることを特徴としている。
【００１０】
請求項１記載の発明によれば、上下方向に所定の間隔を有して架設されている上側の横向き固定棒と下側の横向き固定棒の前側に接近して配線用ボックス本体を位置させ、上側の横向き固定棒に第１凹手段と上アーム片の間を前後方向で対向させるとともに、下側の横向き固定棒に第２凹手段と下アーム片の間を前後方向で対向させて、配線用ボックス本体を後方に押し込むこ簡単な操作により、上アーム片に形成されている誘導面に上側の横向き固定棒が当接し、ついで誘導面に誘導されて上アーム片が上方に弾性変形して、上側の横向き固定棒が第１凹手段に受け入れられ、かつ上アーム片により上側の横向き固定棒を上方より押圧するとともに、下アーム片の係止部に形成されている誘導面に下側の横向き固定棒が当接し、ついで誘導面に誘導されて下アーム片が下方に弾性変形して、下側の横向き固定棒が第２凹手段に受け入れられ、かつ下アーム片により下側の横向き固定棒を下方より押圧した配線用ボックス本体の装着状態を得ることができる。
また、第１凹手段に上側の横向き固定棒が受け入れられることで、配線用ボックス本体の上方および前後方向の移動を拘束することができるとともに、第２凹手段に下側の横向き固定棒が受け入れられることで、配線用ボックス本体の下方および前後方向の移動を拘束することができる。
【００１１】
請求項２記載の発明によれば、左右方向に所定の間隔を有して架設されている左側の立上がり固定棒と右側の立上がり固定棒の前側に接近して配線用ボックス本体を位置させ、左側の立上がり固定棒に第１凹手段と左アーム片の間を前後方向で対向させるとともに、右側の立上がり固定棒に第２凹手段と右アーム片の間を前後方向で対向させて、配線用ボックス本体を後方に押し込むこ簡単な操作により、左アーム片の係止部に形成されている誘導面に左側の立上がり固定棒が当接し、ついで誘導面に誘導されて左アーム片が左方に弾性変形して、左側の立上がり固定棒が第１凹手段に受け入れられ、かつ左アーム片により左側の立上がり固定棒を左方より押圧するとともに、右アーム片の係止部に形成されている誘導面に右側の立上がり固定棒が当接し、ついで誘導面に誘導されて右アーム片が右方に弾性変形して、右側の立上がり固定棒が第２凹手段に受け入れられ、かつ右アーム片により右側の立上がり固定棒を右方より押圧した配線用ボックス本体の装着状態を得ることができる。
また、第１凹手段に左側の立上がり固定棒が受け入れられることで、配線用ボックス本体の左方および前後方向の移動を拘束することができるとともに、第２凹手段に右側の立上がり固定棒が受け入れられることで、配線用ボックス本体の右方および前後方向の移動を拘束することができる。
【００１２】
請求項３記載の発明によれば、上部側壁における第１凹手段の凹溝の形成位置の肉厚が薄くなり過ぎて、上部側壁の強度が低下するのを防止するとともに、上部側壁の強度低下を避けるために必要以上に上部側壁の肉厚を厚くする無駄を避けることもできる。また、下部側壁における第２凹手段の凹溝の形成位置の肉厚が薄くなり過ぎて、下部側壁の強度が低下するのを防止するとともに、下部側壁の強度低下を避けるために必要以上に下部側壁の肉厚を厚くする無駄を避けることもできる。
【００１３】
請求項４記載の発明によれば、左部側壁における第１凹手段の凹溝の形成位置の肉厚が薄くなり過ぎて、左部側壁の強度が低下するのを防止するとともに、左部側壁の強度低下を避けるために必要以上に左部側壁の肉厚を厚くする無駄を避けることもできる。また、右部側壁における第２凹手段の凹溝の形成位置の肉厚が薄くなり過ぎて、右部側壁の強度が低下するのを防止することができるとともに、右部側壁の強度低下を避けるために必要以上に右部側壁の肉厚を厚くする無駄を避けることもできる。
【００１４】
【発明の実施の形態】
以下、請求項１記載の発明の一実施の形態を図面に基づいて説明する。図１は後側から見た斜視図、図２は図１のＡ−Ａ線拡大断面図であり、これらの図において、配線用ボックス本体１は合成樹脂で成形されており、四角形の後部側壁１１と、この後部側壁１１の四辺部から連続して上部側壁１２、下部側壁１３、左部側壁１４および右部側壁１５を前側Ｆに延出することで、前面に開口１０を有する有底角筒状に形成されている。そして、後部側壁１１、上部側壁１２、下部側壁１３、左部側壁１４および右部側壁１５のそれぞれには、押圧力を加えることによって分離可能な塞ぎ板１６によって塞がれた複数個の電線管用コネクタの接続口１７が設けられている。
【００１５】
前記配線用ボックス本体１の上部、すなわち上部側壁１２の外面における後部側壁１１の上方延長線上の左右両側には凹溝よりなる第１凹手段１８が上向きに形成され、配線用ボックス本体１の下部、すなわち下部側壁１３の外面における後部側壁１１の下方延長線上の左右両側には凹溝よりなる第２凹手段１９が下向きに形成されている。第１凹手段１８は、上向きに開口する断面略半円形のもので、左右方向には短く形成され、これら第１凹手段１８の間にはその第１凹手段１８の底と同一レベルの左右方向に延びる断面円弧状で浅く長い上向きの溝１８Ａを設けて、第１凹手段１８に連続させている。また、第２凹手段１９は、下向きに開口する断面略半円形のもので、左右方向には短く形成され、これら第２凹手段１９の間にはその第２凹手段１９の底と同一レベルの左右方向に延びる断面円弧状で浅く長い下向きの溝１９Ａを設けて、第２凹手段１９に連続させている。
【００１６】
前記上部側壁１２における上向きの溝１８Ａに近い左右方向の中央部に弾性変形可能な１つの上アーム片２０が連設され、下部側壁１３における下向きの溝１９Ａに近い左右方向の中央部に弾性変形可能な１つの下アーム片２１が連設されている。上アーム片２０は、上部側壁１２の外面から離れる方向に立ち上がる基部２０Ａと、この基部２０Ａの上端から後側に向けて上向きの溝１８Ａとの対向位置まで延びる押圧部２０Ｂとを備えた断面Ｌ字状に形成され、先端部には、先端にかけて斜めにのびる下向きの傾斜面によってなる誘導面２２を備えている。また、下アーム片２１は、下部側壁１３の外面から離れる方向に下がる基部２１Ａと、この基部２１Ａの下端から後側に向けて下向きの溝１９Ａとの対向位置まで延びる押圧部２１Ｂとを備えた断面Ｌ字状に形成され、先端部には、先端にかけて斜めにのびる上向きの傾斜面によってなる誘導面２３を備えている。
【００１７】
つぎに、前記構成の配線用ボックス本体１を上側の横向き固定棒２Ａと下側の横向き固定棒２Ｂに装着する手順について説明する。上側の横向き固定棒２Ａと下側の横向き固定棒２Ｂは、配線用ボックス本体１の押し込み時に弾性撓み変形が可能なもので、図３に示すように、上下方向に所定の間隔Ｈを有して間仕切り用の柱体５，５に架設されている。なお、前記間隔Ｈは、配線用ボックス本体１における第１凹手段１８と第２凹手段１９の上下方向の間隔Ｈ１と略等しい値に設定されている。まず、図４に示すように、上側の横向き固定棒２Ａと下側の横向き固定棒２Ｂの前側に接近して配線用ボックス本体１を位置させ、上側の横向き固定棒２Ａに第１凹手段１８および溝１８Ａと上アーム片２０の間を前後方向で対向させるとともに、下側の横向き固定棒２Ｂに第２凹手段１９および溝１９Ａと下アーム片２１の間を前後方向で対向させる。
【００１８】
この状態で例えば配線用ボックス本体１の上側を後方（矢印Ｒ方向）に押し込む。これにより、図５に示すように、上側の横向き固定棒２Ａが上アーム片２０の誘導面２２に当接し、かつ第１凹手段１８それぞれの後壁１８ｂの上端部に当接する。この状態から配線用ボックス本体１をさらに後方に押し込むことで、上側の横向き固定棒２Ａは誘導面２２に誘導されて上アーム片２０の押圧部２０Ｂを上方に弾性変形させ、図６および図７に示すように、上側の横向き固定棒２Ａが第１凹手段１８および溝１８Ａに受け入れられ、かつ上アーム片２０により上側の横向き固定棒２Ａを上方より押圧する。ついで、配線用ボックス本体１の下側を後方（矢印Ｒ方向）に押し込む。これにより、図８に示すように、下側の横向き固定棒２Ｂが下アーム片２１の誘導面２３に当接し、かつ第２凹手段１９それぞれの後壁１９ｂの下端部に当接する。この状態から配線用ボックス本体１をさらに後方に押し込むことで、下側の横向き固定棒２Ｂは誘導面２３に誘導されて下アーム片２１の押圧部２１Ｂを下方に弾性変形させ、図９および図１０に示すように、下側の横向き固定棒２Ｂが第２凹手段１９および溝１９Ａに受け入れられ、かつ下アーム片２１により下側の横向き固定棒２Ｂを下方より押圧した配線用ボックス本体１の装着状態（図１１参照）を得ることができる。
【００１９】
すなわち、間仕切り用の柱体５，５に架設されている上側の横向き固定棒２Ａと下側の横向き固定棒２Ｂに対して、前側から配線用ボックス本体１を押し込む簡単な操作によって、配線用ボックス本体１を上側の横向き固定棒２Ａと下側の横向き固定棒２Ｂに対して容易に装着することができる。
【００２０】
一方、第１凹手段１８に上側の横向き固定棒２Ａが受け入れられることで、配線用ボックス１の上方および前後方向の移動を拘束することになり、第２凹手段１９に下側の横向き固定棒２Ｂが受け入れられることで、配線用ボックス１の下方および前後方向の移動を拘束することになるので、上側の横向き固定棒２Ａと下側の横向き固定棒２Ｂに対して配線用ボックス本体１を強固に装着して、不本意な位置ずれや脱落等の発生を確実に防止できる強固な装着強度を得ることができる。
【００２１】
また、上部側壁１２の外面における後部側壁１１の上方延長線上に第１凹手段１８を上向きに形成し、下部側壁１３の外面における後部側壁１１の下方延長線上に第２凹手段１９を下向きに形成しているので、上部側壁１２における第１凹手段１８の形成位置の肉厚が薄くなり過ぎて、上部側壁１２の強度が低下するのを防止するとともに、上部側壁１２の強度低下を避けるために必要以上に上部側壁１２の肉厚を厚くする無駄を避けることもできる。そして、下部側壁１３における第２凹手段１９の形成位置の肉厚が薄くなり過ぎて、下部側壁１３の強度が低下するのを防止するとともに、下部側壁１３の強度低下を避けるために必要以上に下部側壁１３の肉厚を厚くする無駄を避けることもできる。
【００２２】
前記実施の形態では、第１凹手段１８の間に左右方向に延びる断面円弧状で浅く長い上向きの溝１８Ａを設けて、第１凹手段１８を連続させ、第２凹手段１９の間に左右方向に延びる断面円弧状で浅く長い上向きの溝１９Ａを設けて、第２凹手段１９を連続させているが、溝１８Ａ、１９Ａを省略して角落しに代え、第１凹手段１８と第２凹手段１９のみとした構造でもよい。
また、第１凹手段１８と第２凹手段１９を配線用ボックス１の左右方向中央部に１つ所定の広幅で設けてもよい。
また、第１凹手段１８を上方にずらして、第１凹手段１８の底を上部側壁１２の外面に対し同一レベルまたは少し上方にずらし、また、第２凹手段１９を下方にずらして、第２凹手段１９の底を下部側壁１３の外面に対し同一レベルまたは右方にずらして、溝１８Ａ，１９Ａを省略するようにしてもよい。
また、第１凹手段１８と第２凹手段１９は、それ自体底をもつ凹型形状のものに限らず、上側の横向き固定棒２Ａと下側の横向き固定棒２Ｂを溝１８Ａ、１９Ａに入れる構成の場合あるいは上部側壁１２と下部側壁１３の外面に当接させる構成の場合は、前後の対向壁部だけでもよい。すなわち、第１凹手段１８と第２凹手段１９は前後の対向壁部と溝１８Ａ、１９Ａまたは上下部の側壁１２，１３とが組み合わさって右側面視または左側面視で凹状をなしておればよく、そのようなものも含む意味である。
また、上アーム片２０の基部２０Ａと下アーム片２１の基部２１Ａを前側にずらせば、第１凹手段１８と第２凹手段１９を左部側壁１４と右部側壁１５の上下部に設けて実施することもできるし、第１凹手段１８と第２凹手段１９の全体を上部側壁１２の外面と下部側壁１３の外面に設けることができ、また、上アーム片２０の基部２０Ａと下アーム片２１の基部２１Ａを後側にずらせば、第１凹手段１８と第２凹手段１９の全体を後部側壁１１の上部と下部に設けることもできる。
【００２３】
つぎに、請求項２記載の発明の一実施の形態を図面に基づいて説明する。なお、前記請求項１記載の発明と同一もしくは相当部分には、同一符号を付して詳しい構造説明は省略する。図１２は請求項２記載の発明を後側から見た斜視図、図１３は図１２のＤ−Ｄ線拡大断面図であり、これらの図において、左部側壁１４の外面における後部側壁１１の左方延長線上の上下両側に凹溝よりなる第１凹手段１８が左向きに形成され、右部側壁１５の外面における後部側壁１１の右方延長線上の上下両側に凹溝よりなる第２凹手段１９が右向きに形成されている。
【００２４】
第１凹手段１８は、左向きに開口する断面略半円形のもので、上下方向には短く形成され、これら第１凹手段１８の間に上下方向に延びる断面円弧状で浅く長い左向きの溝１８Ａを設けて、第１凹手段１８を連続させている。また、第２凹手段１９は、右向きに開口する断面略半円形のもので、上下方向には短く形成され、これら第２凹手段１９の間に上下方向に延びる断面円弧状で浅く長い右向きの溝１９Ａを設けて、第２凹手段１９を連続させている。
【００２５】
左部側壁１４における左向きの溝１８Ａに近い上下方向の中央部に弾性変形可能な１つの左アーム片２０が連設され、右部側壁１５における右向きの溝１９Ａに近い上下方向の中央部に弾性変形可能な１つの右アーム片２１が連設されている。左アーム片２０は、左部側壁１４の外面から離れる方向にのびる基部２０Ａと、この基部２０Ａの左端から後側に向けて左向きの溝１８Ａとの対向位置まで延びる押圧部２０Ｂとを備えた断面Ｌ字状に形成され、先端部には、先端にかけて斜めにのびる右向きの斜面によってなる誘導面２２を備えている。また、右アーム片２１は、右部側壁１５の外面から離れる方向にのびる基部２１Ａと、この基部２１Ａの右端から後側に向けて右向きの溝１９Ａとの対向位置まで延びる押圧部２１Ｂとを備えた断面Ｌ字状に形成され、先端部には、先端にかけて斜めにのびる左向きの斜面によってなる誘導面２３を備えている。
【００２６】
つぎに、前記構成の配線用ボックス本体１を左側の立上がり固定棒２Ｃと右側の立上がり固定棒２Ｄに装着する手順について説明する。左側の立上がり固定棒２Ｃと右側の立上がり固定棒２Ｄは、配線用ボックス本体１の押し込み時に弾性撓み変形が可能なもので、図１４に示すように、左右方向に所定の間Ｗを有して、たとえば、二重天井などの空間４に設けられている。なお、前記空間Ｗは、配線用ボックス本体１における第１凹手段１８と第２凹手段１９の左右方向の間隔Ｗ１と略等しい値に設定されている。まず、図４に示すように、左側の立上がり固定棒２Ｃと右側の立上がり固定棒２Ｄの前側に接近して配線用ボックス本体１を位置させ、左側の立上がり固定棒２Ｃに第１凹手段１８および溝１８Ａと左アーム片２０の間を前後方向で対向させるとともに、右側の立上がり固定棒２Ｄに第２凹手段１９および溝１９Ａと右アーム片２１の間を前後方向で対向させる。
【００２７】
この状態で例えば配線用ボックス本体１の左側を後方（矢印Ｒ方向）に押し込む。これにより、図５に示すように、左側の立上がり固定棒２Ｃが左アーム片２０の誘導面２２に当接し、かつ第１凹手段１８それぞれの後壁１８ｂの左端部に当接する。この状態から配線用ボックス本体１をさらに後方に押し込むことで、左側の立上がり固定棒２Ｃは誘導面２２に誘導されて左アーム片２０の押圧部２０Ｂを左方に弾性変形させ、図６および図７に示すように、左側の立上がり固定棒２Ｃが第１凹手段１８および溝１８Ａ受け入れられ、かつ左アーム片２０により左側の立上がり固定棒２Ｃを左方より押圧する。ついで、配線用ボックス本体１の右側を後方（矢印Ｒ方向）に押し込む。これにより、図８に示すように、右側の立上がり固定棒２Ｄが右アーム片２１の誘導面２３に当接し、かつ第２凹手段１９それぞれの後壁１９ｂの右端部に当接する。この状態から配線用ボックス本体１をさらに後方に押し込むことで、右側の立上がり固定棒２Ｄは誘導面２３に誘導されて右アーム片２１の押圧部２１Ｂを右方に弾性変形させ、図９および図１０に示すように、右側の立上がり固定棒２Ｄが第２凹手段１９および溝１９Ａに受け入れられ、かつ右アーム片２１により右側の立上がり固定棒２Ｄを右方より押圧した配線用ボックス本体１の装着状態（図１５参照）を得ることができる。
【００２８】
すなわち、図１５に示す二重天井の空間４に設けられている左側の立上がり固定棒２Ｃと右側の立上がり固定棒２Ｄに対して、前側から配線用ボックス本体１を押し込む簡単な作業によって、配線用ボックス本体１を左側の立上がり固定棒２Ｃと右側の立上がり固定棒２Ｄに対して容易に装着することができる。このため、配線用ボックス本体１を二重天井の空間４の所定位置に配設する作業も容易になる。
【００２９】
一方、第１凹手段１８に左側の立上がり固定棒２Ｃが受け入れられることで、配線用ボックス１の左方および前後方向の移動を拘束することになり、第２凹手段１９に右側の立上がり固定棒２Ｄが受け入れられることで、配線用ボックス１の右方および前後方向の移動を拘束することになるので、左側の立上がり固定棒２Ａと右側の立上がり固定棒２Ｄに対して配線用ボックス本体１を強固に装着して、不本意な位置ずれや脱落等の発生を確実に防止できる強固な装着強度を得ることができる。
【００３０】
また、左部側壁１４の外面における後部側壁１１の左方延長線上に第１凹手段１８を形成し、右部側壁１５の外面における後部側壁１１の右方延長線上に第２凹手段１９を形成しているので、左部側壁１４における第１凹手段１８の形成位置の肉厚が薄くなり過ぎて、左部側壁１４の強度が低下するのを防止するとともに、左部側壁１４の強度低下を避けるために必要以上に左部側壁１４の肉厚を厚くする無駄を避けることもできる。そして、右部側壁１５における第２凹手段１９の形成位置の肉厚が薄くなり過ぎて、右部側壁１５の強度が低下するのを防止するとともに、右部側壁１５の強度低下を避けるために必要以上に右部側壁１５の肉厚を厚くする無駄を避けることもできる。
【００３１】
前記実施の形態では、第１凹手段１８の間に上下方向に延びる断面円弧状で浅く長い左向きの溝１８Ａを設けて、第１凹手段１８を連続させ、第２凹手段１９の間に上下方向に延びる断面円弧状で浅く長い左向きの溝１９Ａを設けて、第２凹手段１９を連続させいるが、溝１８Ａ、１９Ａを省略して角落しに代え、第１凹手段１８と第２凹手段１９のみとした構成でもよい。
また、第１凹手段１８と第２凹手段１９を配線用ボックス１の上下方向中央部に１つ所定の広幅で設けてもよい。
また、第１凹手段１８を左方にずらして、第１凹手段１８の底を左部側壁１４の外面に対し同一レベルまたは少し左方にずらし、また、第２凹手段１９を右方にずらして、第２凹手段１９の底を右部側壁１５の外面に対し同一レベルまたは右方にずらして、溝１８Ａ，１９Ａを省略するようにしてもよい。
また、第１凹手段１８と第２凹手段１９は、それ自体底をもつ凹型形状のものに限らず、左側の立上がり固定棒２Ｃと右側の立上がり固定棒２Ｄを溝１８Ａ、１９Ａに入れる構成の場合あるいは左部側壁１４と右部側壁１５の外面に当接させる構成の場合は、前後の対向壁部だけでもよい。すなわち、第１凹手段１８と第２凹手段１９は前後の対向壁部と溝１８Ａ、１９Ａまたは左右部の側壁１４，１５とが組み合わさって上面視または下面視で凹状をなしておればよく、そのようなものも含む意味である。
また、左右アーム片２０，２１の基部２０Ａ，２１Ａを前側にずらせば、第１凹手段１８と第２凹手段１９を上部側壁１２と下部側壁１３の左部と右部に設けて実施することもできるし、第１凹手段１８と第２凹手段１９の全体を左部側壁１４の外面と右部側壁１５の外面に設けて実施することもでき、また、左右アーム片２０，２１の基部２０Ａ，２１Ａを後側にずらせば、第１凹手段１８と第２凹手段１９の全体を後部側壁１１の左部と右部に設けて実施することもできる。
