Description

【０００１】
【発明の属する技術分野】
本発明は、ベランダやバルコニー等に設けたフェンスの柱や手摺りを利用してアンテナを取り付けるアンテナ取付け装置に関する。
【０００２】
【従来の技術】
従来のベランダやバルコニー等に棒体を複数組み合わせて形成した柵状のフェンスを利用して例えばパラボラアンテナを取り付けるアンテナ取付け装置は、図６に示すようなものがあった。これは、フェンス前面に当接させるベース板２１に、パイプ状の本体２２を前方に向けて連結し、アンテナを装着するためのマスト２２ａを上方に折り曲げて形成すると共に、フェンスのうち取付け対象の２本の棒体２６，２６の背部に２枚の圧接具２３を上下に配置し、この圧接具２３とベース板２１とで棒体２６を挟み込み、４本のボルト２４，２４・・をそれぞれ圧接具２３からベース板２１に挿通して棒体２６を挟持し、ベース板２１を棒体２６に圧接固定することでマスト２２ａをフェンスに取付けていた。
【０００３】
【発明が解決しようとする課題】
しかし、上記構成の場合、少なくとも２本の棒体を使用しなければ安定した取付けができないため、棒体の間隔により使用できない場合があったし、パイプ状の本体２２はベース板２１に立設される形態であるため、本体２２を溶接してベース板２１に固着しなければならず、作製に工数がかかっていた。また、部品点数も多く高価なものとなっていたし、４個のボルト２４，２４・・の締め付け操作をしなければならず、取付けも面倒であった。
そこで、本発明は上記問題点に鑑み、部品点数を削減すると共に、取付けも容易なアンテナ取付け装置を提供することを課題とする。
【０００４】
【課題を解決するための手段】
上記課題を解決するため、請求項１の発明に係るアンテナ取付け装置は、後方に延びた胴部と上方に延びたマスト部とを有する本体と、前記胴部に直接形成されて前記胴部の中心軸に平行で該胴部の上下から突出する２つの突起片と、前記胴部を取付け対象に直交交差させて、該取付け対象に前記２つの突起片を圧接させた状態で前記取付け対象に前記胴部を固定する固定手段と、を有することを特徴とする。
【０００５】
請求項２の発明は、請求項１の発明において、前記固定手段が、前記取付け対象に直交交差させた前記胴部の前後位置に形成した貫通孔に挿通するＵボルトであって、該Ｕボルトを締着することで前記取付け対象を前記２つの突起片と前記Ｕボルトとで挟持し、前記２つの突起片を前記取付け対象に圧接固定することを特徴とする。また、請求項３の発明は、請求項１又は２の発明において、前記２つの突起片によって、前記胴部が前記取付け対象に複数部位で接触することを可能にしたことを特徴とする。
【０００８】
【発明の実施の形態】
以下、本発明を具体化した実施の形態を、図面に基づいて詳細に説明する。図１（ａ）は本発明に係るアンテナ取付け装置の一例を示す斜視図であり、パイプを略Ｌ字状に折り曲げて形成された本体１と、当て板２と、Ｕボルト３及びＵボルト３を固定する２個のナット４，４等から構成されている。
【０００９】
本体１は、上方に伸びたマスト部１ａと後方に延びた胴部１ｂとから成り、胴部１ｂにはＵボルト３を挿通する横方向の貫通孔５，５及びマスト部１ａの方向に平行な上下方向の貫通孔６，６が設けられている。
当て板２は固定補助手段であり、断面略コ字状に折り曲げ形成され、平行に配置された上下の折り曲げ辺２ａ，２ｂの先端は取付け対象の棒体に当接する圧接辺であり、平坦な背面が本体胴部１ｂに沿って当接するように配置される。また、本体１に形成した横方向の貫通孔５又は上下方向の貫通孔６に対応する孔７，７が穿設され、棒体に当接する圧接辺の中央にはアールを有する切り欠き９が形成されている。
【００１０】
図１（ｂ）は、上記アンテナ取付け装置を上下に伸びた棒体１０に取り付けた状態を示す胴部を断面で示した正面図であり、図示するように立設されている棒体１０に取付ける場合、まず胴部１ｂを棒体１０に直交交差するように配置し、胴部側部の設けられた貫通孔５の形成位置に合わせて当て板２を当てがい、上下の折り曲げ辺２ａ，２ｂの端部圧接辺を棒体１０に当接させ、棒体１０の反対方向から棒体１０を挟み込むようにＵボルト３を当て板２の孔７，７続いて本体の貫通孔５，５のそれぞれに挿通し、挿通先端部にナット４を螺入して締め付ける。こうすることで、棒体１０は胴部とＵボルトで挟持されて胴部１ｂは棒体１０に圧接固定され、立設されたマスト部１ａにアンテナを装着することができる。
【００１１】
このように、棒状の取付け対象に胴部を直交交差させることで胴部を一方の挟持部材と兼用させて固定手段であるＵボルトと共に取付け対象を挟持するので、図６に示すベース板のような部材が必要なく、作製が容易であるし部品点数も少なくて済む。また、取付け対象は一本の棒体であるので、フェンスのように複数の棒体が列設されていても、パイプ状の本体及び当て板が挿入できる空間さえあれば取り付けでき、棒体の間隔により取付け制限を受けることが無い。また、取付け操作も２ヶ所のボルト締着操作のみで良く、取付け操作が簡単である。
尚、横方向に配設された手摺り等の棒体に対しては、上下方向に設けられた貫通孔６を利用し、当て板をその貫通孔に合わせて胴部の上部或いは下部に配置し、胴部を手摺りに直交交差させることで取り付けでき、容易にマスト部１ａを立設することができる。また、上記実施の形態では当て板を本体胴部と圧接対象との間に介在させているが、安定した装着が可能であればこの当て板は省いても良く、そうすることで部材を更に削減できる。
【００１２】
図２は本発明の第２の実施形態を示す本体胴部を断面で示した正面図であり、上記実施形態の当て板２と本体胴部１ｂの間に更に固定補助部材としてアダプタ１２を介在させている。アダプタ１２は、胴部１ｂに当接する背部１２ａがパイプ状の胴部の径に略等しい径の凹部を有して形成され、背部全体が胴部１ｂに接触するように形成されている。このアダプタ１２は金属板をプレス成形して形成しても、また合成樹脂或いはゴムで形成しても良く、このような部材を介在させることで、胴部１ｂがパイプ形状であっても、がたつくこと無く確実に取り付けることができる。
【００１３】
図３は本発明の第３の実施形態を示す胴部を断面で示した正面図であり、図１の構成において胴部１ｂの当て板当接部を平坦化して、当て板２と面接触するように形成している。このように当て板２と胴部１ｂとの接触部を広く取ることで、アダプタを用いることなく良好な取付けが可能となる。
【００１４】
図４は第４の実施形態を示す斜視図であり、胴部１ｂの取付け対象当接部位を切り欠いて胴部の中心軸に平行な２本の舌片１３，１３を形成している。このように平行な２本の突起辺を胴部１ｂに直接形成して上下２ヶ所で圧接動作させることで、別途当て板を用いなくてもがたつくことなく良好に取付けができ、更に部材を削減できる。
【００１５】
図５は第５の実施形態を示す斜視図であり、固定手段を圧接具１４と２本のボルト１５，１５で形成している。圧接具１４は略コ字状に折り曲げられ当て板２と同様に上下２ヶ所で取付け対象に圧接するよう形成されている。こうすることで、当て板２の折り曲げ辺２ａ，２ｂの当接部に対応する２ヶ所で取付け対象を挟持操作できるので、更に確実な取付けができる。
尚、この圧接具は対応する当て板の如く、中央部にアールを有する切り欠きを設けると取付け対象が円柱状の棒体の場合良好に取付けでき好ましい。
【００１６】
【発明の効果】
以上詳述したように、請求項１から３の発明によれば、手摺りやフェンスの柱等に胴部を直交交差させることで胴部を一方の挟持部材と兼用させるので、胴部を溶接固着するベース板のような部材が必要なく、作製が容易であるし部品点数も少なくて済む。また、取付け操作も２ヶ所のボルト締着操作のみで良く、取付け操作が簡単である。
更に、取付け対象は一本の棒体で済むので、フェンス等の柱材の間隔により取付け制限を受けることが無く、本体胴部を挿通出来る隙間さえあれば取付けできるし、胴部に設けるボルト挿通孔を上下左右の直交する２方向に設ければ、圧接対象の棒体が縦方向だけでなく横方向に配置されていてもマストの立設配置が容易に実現できる。
【００１７】
また、請求項３の発明によれば、胴部を直接取付け対象に当接させても確実な固定ができ、部材を更に削減できる。
