Description

【0001】
【発明の属する技術分野】
本発明は複数のアンテナを支持する為のアンテナ支持具に関する。
【0002】
【従来の技術】
夫々先部にアンテナ取付部を備えている2本のアームは、その元部に支柱に対する添え片を備えている。各アームの添え片を支柱の一方側と他方側とに夫々沿わせる。そして一方の添え片、支柱、他方の添え片の順にボルトを差し通し、ナットで締め付けることにより、2本のアームを支柱に固定するようにしている(例えば実開昭52−166438号公報参照)。
【0003】
このようなものは、二つのアンテナを設置しようとする場合、アンテナ支持用の上記2本のアームを支柱の両側に対称的に取り付けることが出来るので、それらの先部に取り付けるアンテナ相互の位置関係が一定に定まる特長がある。
【0004】
【発明が解決しようとする課題】
しかしこの従来のアンテナ支持具では、上記取り付け作業の場合、上記2本のアームを夫々手で持ち、夫々のアームにおける添え片を支柱の両側に沿わせる。そしてその状態を保持したまま、上記ボルトを差し通してナット締めを行わねばならぬ。これらの作業を一人で行うことは困難で、複数人の作業員を必要とする問題点があった。又上記アームの保持の為に作業員に不安定な姿勢を強いる為、特に高所での取り付け作業の場合には非常に危険であるという問題点があった。
【0005】
本願発明のアンテナ支持具は上記従来技術の問題点を解決する為に提供するものである。
本願発明の目的は、アンテナ支持用の複数のアームを備えていて、複数のアンテナを所定の位置関係に設置することが出来るアンテナ支持具を提供することである。
他の目的は、上記複数のアームの取り付け作業を一人の作業員で行うことを可能に出来るようにすることである。
他の目的は、複数のアームの夫々について個別に仮止めが出来るようにすることによって、高所での取り付け作業であってもそれを安全に行い得るようにすることである。
他の目的は、複数のアームを夫々受部材に取り付ける場合、受部材が頭上の位置にあっても、仮止め用の手段を下から目で見ながらアームを操作することが出来て、容易に上記仮止め状態を達成できるようにすることである。
他の目的及び利点は図面及びそれに関連した以下の説明により容易に明らかになるであろう。
【0006】
【課題を解決するための手段】
上記目的を達成する為に、本願発明におけるアンテナ支持具は、夫々は先部にアンテナ取付部を備えると共に元部に支持杆取付部を備えている複数のアームと、それらのアームの支持杆取付部と支持杆を結合する為の結合具とから成るアンテナ支持具において、上記結合具は、支持杆に対する連結部を有する本体と、夫々上記本体から側方に延び、各々は上記支持杆取付部を乗せる為の受面を備えている複数の受部材とから成り、上記各アームの支持杆取付部には、下側に突出する横止片と、その横止片の下部から上記支持杆取付部において上記受面に乗せる為の乗載面と対向する側に向けて突出する下止片とを備えさせ、上記受部材には、上記受面に上記乗載面を乗せた状態において、上記横止片と対峙して支持杆取付部の横ずれを阻止する為の横位置規制部と、上記下止片と対峙して支持杆取付部の浮き上がりを阻止する為の浮上規制部を備えさせて、上記受面に上記乗載面を乗せると共に、上記横止片及び下止片を夫々下側から目視可能な状態で上記横位置規制部及び浮上規制部と夫々対峙させることにより、支持杆取付部が受部材に仮止めされるようにしたたものである。
【0007】
【発明の実施の形態】
以下本願発明の実施の形態を示す図面について説明する。アンテナの設置状態を示す図1において、Aは支持杆で、アンテナを支持する為のベースとなる部材であり、支柱(マストとも呼ばれる)を例示する。Bは複数のアンテナを所定の位置関係に支持する為のアンテナ支持具、Cは上記支持具Bによって支持されたアンテナを夫々示す。支持杆Aは、アンテナの設置状態において人の頭が支持具BやアンテナCに当ったりすることがないように出来る高さが選ばれ、例えば1.8m或いはそれ以上の高さであったり、ビルの側壁1aから側方に突出するアームであったりする。1はアンテナの設置場所として例示する建物の屋上の床面、2はそこに備えた基礎で、コンクリート製の台を示す。3は支柱Aの下端に備えたベース、4はベース3を上記台2に取付ける為のボルトを示す。
【0008】
次にアンテナ支持具Bは、その流通過程や設置の為の運搬時の嵩張りを小さくする為に、相互に別体となった複数のアームB1と結合具B2とにより構成している。複数のアームB1は夫々アンテナCを相互に離間させた状態で支える為のもので、その離間の為の長さ例えば60cmを有するものであり、結合具B2はそれらのアームB1を支柱Aに結合させる為のものである。各アームB1におけるB11はアンテナの取付を行う為のアンテナ取付部を示し、B12は支持杆に対する取付を行う為の支持杆取付部を示す。これらは上記のようにアンテナCを相互に離間させる為に、アームB1の一方の端部と他方の端部に夫々設けている。支持杆取付部B12はアームB1の支持の根本側となる為、後者の端部を元部とも呼び、前者の端部を先部とも呼ぶ。上記アームB1は軽量化及びアンテナCの重量に耐える為に例えばアルミのパイプで形成している。B21は結合具B2におけるベースとなる本体、B22は各アームB1の支持杆取付部B12を取り付ける為の受部材を夫々示す。受部材B22はアームB1を横臥状態に支持できるようにする為に本体B21から側方に延びる状態に設けている。符号B22’が本体B21に対する受部材B22の付け根を示す。又受部材B22は、複数(この例では四つ)のアームB1を相互に等角度間隔(この例では90゜)の位置関係で固定する為に、四つの受部材B22を相互に等角度間隔(この例では90゜)の位置関係で備えさせている。これら本体B21及び受部材B22は、製造の手間数を少なくする為に例えばアルミダイカストで一体に形成した例を示すが、別体に形成し、後の工程で一体化しても良い。
【0009】
上記本体B21について図2に基づき説明する。6は支持杆Aに対するしっかりとした固定を行う為の連結部で、例えばパラボラアンテナの支持具において周知の支柱取付部の構造を例示する。即ち、7は支柱の差込孔、8は差込孔の周壁の一部に穿設したねじ孔、9はねじ孔8に螺合させた固定用のボルトである。10は避雷針の取付のためのねじ孔、11は避雷針の不使用時に上記ねじ孔10を塞いでおくための栓である。図3における12は、アームB1における支持杆取付部B12を位置決する為の受止面を示し、アームB1の端面の受止の為に上記付け根B22’から後述の受面16とは交差する状態(例えば垂直)に立ち上がる面に形成している。
【0010】
上記受部材B22について図3に基づき説明する。16はアームB1の支持杆取付部B12をその取付の為に乗せる受面で、アームB1をぐらつくことなく固定できるようにする為に平坦面に形成している。17はアームを固着する為のねじ孔を示す。18は支持杆取付部B12における後述の横止片28aと対峙して支持杆取付部B12の横ずれを阻止する為の横位置規制部で、受部材B22の左右の側面をもって形成している。18aは横位置規制部18の先端部における案内面を示し、横止片を横位置規制部18と対峙する位置にスムーズに導くために斜面(例えば円弧面)に形成している。19は支持杆取付部B12における後述の下止片28bと対峙して支持杆取付部B12の浮き上がりを規制する為の浮上規制部で、受部材B22の下面をもって形成した例を示す。20は受部材B22の補強部材を示す。
【0011】
上記アームB1における支持杆取付部B12について図3に基づき説明する。24は受部材B22の受面16に乗せることによりその受面16と重合状態となる乗載面を示し、受面16に対応した面であるところの平坦面に形成している。25は支持杆取付部B12におけるアームB1の元部側の端面を示す。27はボルト貫通用の透孔、29は支持杆取付部B12を受部材B22に固定するためのボルトを夫々示す。端面25と透孔27との間隔は、後述の如き位置決のときに透孔27とねじ孔17とがぴったりと重合状態となるようにする為に、受止面12とねじ孔17との間隔と一致させてある。28は受部材B22に対する支持杆取付部B12の仮止めを行う為の仮止部材を示し、横止片28aと下止片28bとから成る。これらは下側からの目視が容易なよう、図示の如く横止片28aは下方に向けて突出する状態に設け、下止片28bはその横止片28aの下部から乗載面24と対向する側に向けて側方に突出する状態に設けている。上記仮止部材28はアームB1と一体に形成した例を示す。上記仮止部材28は後述のように受部材B22に対する支持杆取付部B12の位置決手段及びガイド手段としての機能も備えている。
【0012】
図4乃至図6に示す31はボルト29の締付力によって支持杆取付部B12が潰れることを防止する為のスペーサで、支持杆取付部B12の内部においてその上壁B12aと下壁B12bとの間に介在させている。該スペーサ31は硬質の合成樹脂製である。該スペーサ31は上壁B12aと下壁B12bとの間のつっかい棒として作用し、ボルト29によって受部材B22に支持杆取付部B12を固定する場合に、上壁B12a、スペーサ31、下壁B12bを一つの剛体として機能させる。従ってボルト29を締めてもそのボルト頭29aによって支持杆取付部B12の上壁B12aが潰されることはない。又ボルト29の締付力を、支持杆取付部B12を受部材B22に固定する目的に充分に機能させることが出来る。尚32はボルト29の軸部29bを貫通させる為の透孔である。33はボルト29がアームB1の透孔27から抜け落ちることを防止する為の手段を示し、この例では、透孔32の内周面がボルト29の軸部29bにおけるねじ山の先端に圧接することによってボルト29の抜け落ちを防止するようにしている。34はスペーサ31の弾性変形、即ち上記内周面33をボルト29に圧接させる為の弾性変形を容易化する為に設けたスリットを示す。
【0013】
上記支持杆取付部B12は、アンテナの設置現場での作業を容易化する為に、メーカーでの製造の際に次のような状態まで組み立てておかれる。即ち、図6の状態からスペーサ31をアームB1の内部に押し込む。ボルト29は、その軸部29bを上壁B12aの透孔27を通して透孔32内に圧入し、軸部29bが下壁B12bの透孔27から突出せぬ位置まで差し込んでおかれる。
【0014】
図1に示す38はアンテナ取付部B11に備えたアンテナ取付具である。次にアンテナCは、例えば携帯電話用の電波の送受信を行うためのアンテナを示す。重量は例えば1kg程度である。該アンテナCとしてはその他に、無線通信用、アマチュア無線用のアンテナなどがある。39は信号伝送用のケーブルである。
【0015】
次にアンテナ設置場所1でのアンテナCの設置を説明する。設置場所1には予め台2が用意されている。アンテナの設置に当たっては、先ずそこに支柱Aを固定する。固定状態は略鉛直である。次に結合具B2をその支柱Aの先端に図2の如く取付ける。このとき支柱Aを中心に結合具B2を回して、その受部材B22が適正な方向に来るようにする。又この状態では受面16は略水平となる。次に各アンテナCに夫々ケーブル39を接続し、それらのアンテナCを各アームB1のアンテナ取付部B11に夫々アンテナ取付具38でもって取付ける。
【0016】
次に上記結合具B2に対して、上記の各アームB1を夫々取付ける。その取付は以下の通りである。一つのアームB1を手に持ち、それにおける仮止部材28の内側に受部材B22の先端部が入り込むよう、乗載面24の先端部24aを受部材B22における受面16の先端部16aに乗せる。この場合、斜面となった案内面18aがあるのでその操作は容易である。又仮止部材28は支持杆取付部B12の下側に備わっているので、受部材B22の位置が高くて頭上にあっても、仮止部材28内に上記先端部が入り込む状態を下から見ながら行うことが出来、従ってその操作は容易である。上記のように先端部16aの上に先端部24aが乗ったならば、支持杆取付部B12を受面16に沿って本体B21に向けて移動させる。この場合、受面16をガイド面としてその上に沿って乗載面24を滑らせれば良い。又仮止部材28の横止片28a及び下止片28bは夫々ガイド部材となって横位置規制部18及び浮上規制部19に沿って進む。従って上記支持杆取付部B12の移動操作は容易である。上記移動は端面25が受止面12に当接する位置まで行う。
【0017】
上記のような操作により、横止片28aは横位置規制部18と、又下止片28bは浮上規制部19と夫々対峙し、アームB1の支持杆取付部B12は受部材B22に対して仮止め状態となる。即ちアームB1を外から支える必要なく結合具B2に対するアームB1の結合状態を一時的に維持できる状態が達成される。又上記支持杆取付部B12の移動操作が完了した状態では、受止面12と端面25、及び横位置規制部18と横止片28aが夫々位置決手段として機能して、受部材B22に対し支持杆取付部B12は所定の位置決状態となり、透孔27がねじ孔17に対して丁度重合する位置関係となる。
【0018】
上記の状態となったならば、次に受部材B22に対し支持杆取付部B12の本固定を行う。例えばボルト29によって受部材B22に対する支持杆取付部B12の固定を行う。この場合、上記のように位置決がなされている為、ボルト29の軸部29bをスムーズにねじ孔17に進入させることが出来る。又上記のようにアームB1の仮止めがなされている為、アームB1を手で支える必要が無い。従って作業者は、片手で支柱Aにつかまるなどして自身の身体を支え、他方の手で上記ボルト29の操作を行えば良く、作業を安全に行うことが出来る。
【0019】
上記のような作業を複数のアームB1について全て行う。それが済んだならば図1に示されるようにバインド部材41でもってケーブル39を周知の如く固定することにより、アンテナCの設置作業が完了する。
【0020】
次に実施形態の異なる例を説明する。上記各アームB1の固定用のボルト29は1本でも良い。その場合には、該ボルト29によって支持杆取付部B12を受部材B22に固定した状態では、仮止部材28が受部材B22に対するアームB1の固定部材の一つとして機能する。即ちボルト29は受部材B22から支持杆取付部B12が離反することを阻止し、仮止部材28はボルト29を中心とするアームB1の回転を阻止する。
【0021】
次に図7はアームB1e及び仮止部材28eの夫々の形成を容易化する為に、それらを別部材で形成し、後の工程で仮止部材28eを支持杆取付部B12eに対してその下側に突出する状態に備えさせるようにする例を示すものである。図において仮止部材28eはアームに対する連結部43を備えた別の部材42として形成している。連結部43はアームB1eの上側及び両横側を包囲する形状に形成し、該連結部43をアームB1eに止め付ける為の透孔44及び透孔27eと重合するボルト挿通用の透孔45を形成具備させる。上記のような部材42は、例えば金属板をプレス成形して形成したり、プラスチック材料を型成形することによって形成する。上記部材42は図に2点鎖線で示すようにアームB1eにおける支持杆取付部B12eを包み込むように被せ付け、止具として例示する小ねじ46でもってアームB1eに止め付ける。なお、機能上前図のものと同一又は均等の構成で説明が重複すると考えられる部分には、前図と同一の符号にアルファベットのeを付して重複する説明を省略した。(また次図のものにおいても順次同様の考えでアルファベットのf,gを付して重複する説明を省略する。)
【0022】
次に図8は、仮止部材28fを備えるアームB1fを低廉に提供できるようにすることを目的とするものである。図において、仮止部材28fは受部材B22fの左右に位置するものが一つに繋がった状態に形成しており、上部にはアームB1fに対する連結部43fを備える。そしてその連結部43fを小ねじ46fでもってアームB1fに止め付けている。このような構成のものは、アームB1fが単純な杆体で良いのでそれに要する費用が安く、又仮止部材28fも小片でよいのでそれに要する費用が安く、従ってアームB1fを非常に低廉化することが出来る。尚上記仮止部材28fは金属板をプレスして形成したり、プラスチック材料を成形することによって形成する。仮止部材28fは一つのみを備えさせても良い。又受部材B22fにおける補強部材20fは仮止部材28fとの干渉を防ぐ為に図示の如き形状に形成すると良い。
【0023】
次に図9の(A)及び(B)はアームB1gに対する仮止部材28gの止付手段の異なる例を示すものである。(A)は仮止部材28gが簡単にアームB1gに取り付くようにする為に、仮止部材28gに嵌合片47を備えさせ、アームB1gには上記嵌合片47を嵌め込む為の嵌合孔48を備えさせた例を示す。又(B)は仮止部材28gを簡単にアームB1gに取り付けた後、その仮止部材28gがアームB1gから脱落し難くする為に、嵌合片47の先に係止爪49を備えさせた例を示す。この例では、嵌合片47を嵌合孔48に嵌合させると係止爪49が嵌合孔48の縁に引っかかり、嵌合片47が嵌合孔48から外れ難くなる。
【0024】
【発明の効果】
以上のように本願発明にあっては、複数のアンテナCを設置する場合、アンテナ支持用の複数のアームB1における各支持杆取付部B12を、結合具B2に備わっている複数の受部材B22に夫々取付けることによって、それらのアームB1が一定の位置関係で配列され、それらのアームB1に夫々取付けるアンテナCを所定の位置関係に配列できる特長がある。
しかも上記複数のアームB1の取付の場合、各アームB1は夫々の元部の支持杆取付部B12を結合具B2における受部材B22に夫々個別に取り付ければよいので、一つずつ取付を行いうる特長がある。このことは、上記取り付け作業を一人の作業員で行うことを可能に出来る効果がある。
しかも上記アームB1の取付の場合、受面16に乗載面24を乗せ、支持杆取付部B12における横止片28a及び下止片28bを受部材B22における横位置規制部18及び浮上規制部19と夫々対峙させることにより、支持杆取付部B12を受部材B22に仮止め出来る特長がある。このことは、受部材B22に対してアームB1の支持杆取付部B12を本固定する場合、アームB1を別途支えたりする必要がないので、たとえ高所での取付であっても、その作業を安全に行うことを可能に出来る効果がある。
その上上記のようにアームB1の支持杆取付部B12を受部材B22に仮止め状態にする作業の場合、上記横止片28a及び下止片28bは支持杆取付部B12の下側に備えているので、受部材B22が頭上の位置にあっても、それら仮止め用の横止片28a及び下止片28bを下から目で見ながらアームB1を操作することが出来て、容易な作業でもって上記仮止め状態を達成できる作業上の効果がある。

[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, drawings illustrating embodiments of the present invention will be described. In FIG. 1 showing the installation state of the antenna, A is a supporting rod, which is a member serving as a base for supporting the antenna, and exemplifies a column (also called a mast). B denotes an antenna support for supporting a plurality of antennas in a predetermined positional relationship, and C denotes an antenna supported by the support B. The height of the support rod A is selected so that a human head does not hit the support B or the antenna C when the antenna is installed. For example, the height is 1.8 m or more. It may be an arm projecting laterally from the side wall 1a of the building. Reference numeral 1 denotes a rooftop floor of a building exemplified as an antenna installation location, and reference numeral 2 denotes a concrete base provided on the foundation. Reference numeral 3 denotes a base provided at the lower end of the column A, and reference numeral 4 denotes a bolt for attaching the base 3 to the base 2.
[0008]
Next, the antenna support B is composed of a plurality of arms B1 and a coupler B2 which are separate from each other in order to reduce the bulk of the antenna support B during transportation for installation and installation. The plurality of arms B1 are for supporting the antennas C in a state of being separated from each other, and have a length of, for example, 60 cm for the separation, and the coupling tool B2 connects the arms B1 to the column A. It is to make it. B11 in each arm B1 indicates an antenna mounting portion for mounting an antenna, and B12 indicates a support rod mounting portion for mounting to a support rod. These are provided at one end and the other end of the arm B1 to separate the antennas C from each other as described above. Since the support rod mounting portion B12 is on the root side of the support of the arm B1, the end of the latter is also referred to as a base, and the end of the former is also referred to as a front. The arm B1 is formed of, for example, an aluminum pipe in order to reduce the weight and withstand the weight of the antenna C. B21 indicates a main body serving as a base of the coupling tool B2, and B22 indicates a receiving member for mounting the support rod mounting portion B12 of each arm B1. The receiving member B22 is provided so as to extend laterally from the main body B21 so as to be able to support the arm B1 in a lying state. Reference sign B22 'indicates the base of the receiving member B22 with respect to the main body B21. Further, the receiving member B22 is fixed to the four receiving members B22 at an equal angular interval so as to fix a plurality of (four in this example) arms B1 at an equal angular interval (90 ° in this example). (In this example, 90 °). An example is shown in which the main body B21 and the receiving member B22 are integrally formed by, for example, aluminum die casting in order to reduce the number of manufacturing steps, but they may be formed separately and integrated in a later step.
[0009]

[0012]
A spacer 31 shown in FIGS. 4 to 6 is a spacer for preventing the support rod mounting portion B12 from being crushed by the tightening force of the bolt 29. The spacer 31 is formed between the upper wall B12a and the lower wall B12b inside the support rod mounting portion B12. It is interposed between them. The spacer 31 is made of a hard synthetic resin. The spacer 31 functions as a bar between the upper wall B12a and the lower wall B12b, and when the supporting rod mounting portion B12 is fixed to the receiving member B22 by the bolt 29, the upper wall B12a, the spacer 31, and the lower wall B12b are used. Function as one rigid body. Therefore, even if the bolt 29 is tightened, the upper wall B12a of the support rod mounting portion B12 will not be crushed by the bolt head 29a.

The support rod mounting portion B12 is assembled to the following state at the time of manufacture by a manufacturer in order to facilitate the work at the installation site of the antenna. That is, the spacer 31 is pushed into the arm B1 from the state shown in FIG. The bolt 29 presses the shaft portion 29b into the through hole 32 through the through hole 27 in the upper wall B12a, and is inserted until the shaft portion 29b does not protrude from the through hole 27 in the lower wall B12b.
[0014]
Reference numeral 38 shown in FIG. 1 is an antenna mounting tool provided on the antenna mounting portion B11. Next, an antenna C is an antenna for transmitting and receiving radio waves for mobile phones, for example. The weight is, for example, about 1 kg. Other examples of the antenna C include a radio communication antenna and an amateur radio antenna. 39 is a signal transmission cable.
[0015]
Next, the installation of the antenna C at the antenna installation location 1 will be described. A table 2 is prepared in the installation location 1 in advance. When installing the antenna, first, the column A is fixed thereto. The fixed state is substantially vertical. Next, the coupling tool B2 is attached to the tip of the column A as shown in FIG. At this time, the coupling member B2 is turned around the column A so that the receiving member B22 comes in an appropriate direction. In this state, the receiving surface 16 is substantially horizontal. Next, cables 39 are connected to the respective antennas C, and the antennas C are mounted on the antenna mounting portions B11 of the respective arms B1 with the respective antenna mounting members 38.
[0016]
Next, each of the arms B1 is attached to the coupler B2. The mounting is as follows. Hold one arm B1 in hand and place the distal end 24a of the mounting surface 24 on the distal end 16a of the receiving surface 16 of the receiving member B22 so that the distal end of the receiving member B22 enters the temporary fixing member 28 therein. . In this case, the operation is easy because the inclined guide surface 18a is provided. In addition, since the temporary fixing member 28 is provided below the support rod mounting portion B12, even when the receiving member B22 is at a high position and is above the head, the state in which the above-described distal end portion enters the temporary fixing member 28 is viewed from below. While the operation is easy. When the distal end portion 24a rides on the distal end portion 16a as described above, the support rod mounting portion B12 is moved along the receiving surface 16 toward the main body B21. In this case, the receiving surface 16 may be used as a guide surface and the mounting surface 24 may be slid along the guide surface. Further, the lateral stopper 28a and the lower stopper 28b of the temporary fixing member 28 serve as guide members, and advance along the lateral position restricting portion 18 and the floating restricting portion 19, respectively. Therefore, the operation of moving the support rod mounting portion B12 is easy. The above movement is performed until the end face 25 comes into contact with the receiving face 12.
[0017]
By the above-described operation, the lateral stopper 28a faces the lateral position restricting portion 18, the lower stopper 28b faces the floating restricting portion 19, and the supporting rod mounting portion B12 of the arm B1 is temporarily moved with respect to the receiving member B22. It is stopped. That is, a state is achieved in which the connection state of the arm B1 to the coupling tool B2 can be temporarily maintained without the need to support the arm B1 from outside. When the operation of moving the support rod mounting portion B12 is completed, the receiving surface 12 and the end surface 25, and the lateral position restricting portion 18 and the lateral stopper piece 28a function as positioning means, respectively. The support rod mounting portion B12 is in a predetermined positioning state, and has a positional relationship in which the through hole 27 is exactly overlapped with the screw hole 17.
[0018]
When the above state is attained, next, the support rod mounting portion B12 is permanently fixed to the receiving member B22. For example, the support rod mounting portion B12 is fixed to the receiving member B22 by the bolt 29. In this case, since the positioning is performed as described above, the shaft portion 29b of the bolt 29 can smoothly enter the screw hole 17. Since the arm B1 is temporarily fixed as described above, it is not necessary to support the arm B1 by hand. Therefore, the worker only has to support his or her body by holding on to the column A with one hand and operate the bolt 29 with the other hand, and the work can be performed safely.
[0019]
The above operations are all performed on the plurality of arms B1. After that, as shown in FIG. 1, the cable 39 is fixed by the binding member 41 in a known manner, and the installation work of the antenna C is completed.
[0020]
Next, different examples of the embodiment will be described. The number of fixing bolts 29 for each arm B1 may be one. In this case, in a state where the support rod mounting portion B12 is fixed to the receiving member B22 by the bolt 29, the temporary fixing member 28 functions as one of the fixing members of the arm B1 to the receiving member B22. That is, the bolt 29 prevents the support rod mounting portion B12 from separating from the receiving member B22, and the temporary fixing member 28 prevents the rotation of the arm B1 about the bolt 29.
[0021]
Next, FIG. 7 shows that in order to facilitate the formation of the arm B1e and the temporary fixing member 28e, they are formed as separate members, and the temporary fixing member 28e is placed below the supporting rod mounting portion B12e in a later step. This is an example in which the robot is prepared for a state of protruding to the side. In the drawing, the temporary fixing member 28e is formed as another member 42 having a connecting portion 43 for the arm. The connecting portion 43 is formed in a shape surrounding the upper side and both lateral sides of the arm B1e, and has a through hole 44 for fastening the connecting portion 43 to the arm B1e and a through hole 45 for bolt insertion overlapping with the through hole 27e. It is formed. The member 42 as described above is formed, for example, by pressing a metal plate or by molding a plastic material. The member 42 is covered so as to wrap around the support rod mounting portion B12e of the arm B1e as shown by a two-dot chain line in the figure, and is fixed to the arm B1e with a small screw 46 exemplified as a stopper. Note that, for functionally the same or equivalent configuration as that of the previous figure, the description of which is considered to be duplicated is omitted by adding the same reference numeral as the previous figure to the letter e of the alphabet and duplicating the description. (Also in the following figures, alphabetical letters f and g are added in the same manner in order, and duplicate explanations are omitted.)
[0022]
Next, FIG. 8 aims at providing the arm B1f provided with the temporary fixing member 28f at low cost. In the figure, the temporary fixing member 28f is formed in a state where the members located on the left and right sides of the receiving member B22f are connected to one, and the upper portion is provided with a connecting portion 43f for the arm B1f. The connecting portion 43f is fixed to the arm B1f with a small screw 46f. In such a configuration, the arm B1f may be a simple rod, so that the cost required for the arm B1f is low, and the temporary fixing member 28f may be a small piece, so that the cost required for it is low. I can do it. The temporary fixing member 28f is formed by pressing a metal plate or by molding a plastic material. Only one temporary fixing member 28f may be provided. The reinforcing member 20f of the receiving member B22f may be formed in a shape as shown in the drawing in order to prevent interference with the temporary fixing member 28f.
[0023]
Next, FIGS. 9A and 9B show different examples of the means for fastening the temporary fixing member 28g to the arm B1g. (A) shows that the temporary fixing member 28g is provided with a fitting piece 47 so that the temporary fixing member 28g can be easily attached to the arm B1g, and a fitting for fitting the fitting piece 47 into the arm B1g. An example in which holes 48 are provided is shown. In (B), after the temporary fixing member 28g is easily attached to the arm B1g, a locking claw 49 is provided at the tip of the fitting piece 47 so that the temporary fixing member 28g does not easily fall off the arm B1g. Here is an example. In this example, when the fitting piece 47 is fitted into the fitting hole 48, the locking claw 49 is caught on the edge of the fitting hole 48, and it is difficult for the fitting piece 47 to come off the fitting hole 48.
[0024]
【The invention's effect】
As described above, in the present invention, when a plurality of antennas C are installed, the support rod mounting portions B12 of the plurality of arms B1 for supporting the antenna are attached to the plurality of receiving members B22 provided in the coupling tool B2. By attaching each of them, the arms B1 are arranged in a fixed positional relationship, and the antenna C attached to each of the arms B1 is arranged in a predetermined positional relationship.
In addition, in the case of mounting the plurality of arms B1, since the arms B1 need only be individually mounted on the support rod mounting portions B12 of the respective base portions on the receiving members B22 of the coupler B2, the feature that each arm B1 can be mounted one by one. There is. This has the effect that it is possible to perform the mounting operation by one worker.
In addition, in the case of mounting the arm B1, the mounting surface 24 is placed on the receiving surface 16, and the horizontal stopper 28a and the lower stopper 28b of the support rod mounting portion B12 are moved to the horizontal position restricting portion 18 and the floating restricting portion 19 of the receiving member B22. Therefore, there is an advantage that the support rod mounting portion B12 can be temporarily fixed to the receiving member B22. This means that when the support rod mounting portion B12 of the arm B1 is permanently fixed to the receiving member B22, it is not necessary to separately support the arm B1, and therefore, even if the mounting is performed at a high place, the work can be performed. There is an effect that can be performed safely.
In addition, in the case where the support rod mounting portion B12 of the arm B1 is temporarily fixed to the receiving member B22 as described above, the horizontal stopper piece 28a and the lower stopper piece 28b are provided below the support rod mounting section B12. Therefore, even when the receiving member B22 is located at the position above the head, the arm B1 can be operated while visually observing the side stoppers 28a and the lower stoppers 28b for temporary fixing from below, and the work is easy. Accordingly, there is an operational effect that can achieve the temporary fixing state.
