【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、アームにおける支持杆取付部を受部材の受面に乗せ、ガイド片をガイドにしてその支持杆取付部をちょっとずらすだけの簡単な操作でもって、アームを確実に仮止め状態に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における乗載面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、上記受部材における受面の両横には上記支持杆取付部の両側部をガイドする為のガイド片を備えさせ、上記本体には、上記受面に上記支持杆取付部を乗せた状態においてその支持杆取付部における端部の上面と対峙してその浮き上がりを阻止する為の浮上阻止片を備えさせて、上記受面に上記支持杆取付部を乗せ、その支持杆取付部を、その両側部を上記ガイド片によりガイドした状態で受面に沿ってずらすことにより、支持杆取付部の端部が上記浮上阻止片の下に入り込んで、支持杆取付部が受部材に仮止めされるようにしたものである。
【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。13はアームB1を仮止めする際にその浮上を阻止する為の浮上阻止片で、後述の受面16に沿って移動される支持杆取付部B12の端部が該浮上阻止片13の下に入り込むことを可能にする為に、受面16からアームB1の高さ寸法に等しい寸法だけ隔てた位置に設けている。
【0010】
上記受部材B22について図3及び図4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である。18はアームB1における支持杆取付部B12をガイドする為のガイド片で、受面16上に乗せられた状態の支持杆取付部B12の両側をガイドする為に受面16の両横において夫々受面16から上方に立ち上がる状態に設けている。両ガイド片18相互の間隔は支持杆取付部B12を実質的にがたつき無くガイドできるようにアームB1の幅寸法に対応させてある。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乃至図5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は前記受止面12と対峙させるようにした面であり、アームB1の元部側の端面をもって該対峙面としている。26は上記ガイド片18によるガイドを受ける為に支持杆取付部B12の両横に備えた被ガイド部で、この例ではアームB1に何等の加工も要することの無いように支持杆取付部B12における側面の下部部分そのものをもって該被ガイド部26としてある。28は上記浮上阻止片13による係止を受ける為に支持杆取付部B12の端部の上面に備えた被係止部を示し、上記被ガイド部と同様の目的で上記端部の上面そのものをもって該被係止部28としてある。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。上記端面25と透孔27との間隔は、後述の如き仮止め状態において透孔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。
【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む。この状態まで組立が行われる。
【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、図7に示すように乗載面24を一つの受部材B22における受面16に乗せる。この状態では支持杆取付部B12における被ガイド部26の両横に受部材B22のガイド片18が夫々位置する。次にそのアームB1を、両横のガイド片18でもって案内しながら受面16に沿って本体B21に向けてずらす。端面25が受止面12に当接するに至ると、図4の如く支持杆取付部B12の端部の被係止部28が浮上阻止片13の下に入り込み、浮上阻止片13は被係止部28と対峙する状態となる。
【0017】
上記のように被係止部28が浮上阻止片13の下に入り込むと、受部材B22に対してアームB1は仮止め状態となる。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。その作用を説明する。アームB1における支持杆取付部B12を上記のように受面16に乗せた状態においては、アームB1はアンテナCが取り付いている先部の側が重いため、アームB1から手を離すと、アームB1は先部の側が下がろうとし、反対に支持杆取付部B12は受面16の先端をてこの支点にしてが浮き上がろうとする。しかし上記被係止部28の上に対峙する浮上阻止片13がその支持杆取付部B12の浮き上がりを阻止する。このようにしてアームB1が仮止め状態に保持される。
【0018】
又上記のようにして仮止め状態にした場合、支持杆取付部B12はその左右の両横が両ガイド片18によって左右方向に位置規制され、又端面25が受止面12に当接して前後方向に位置規制されているので、受部材B22に対して支持杆取付部B12は正確に位置決され、下壁B12bの透孔27はねじ孔17に対してぴったりと重合する状態となる。
【0019】
上記仮止め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。
【0020】
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。
【0021】
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、支持杆取付部B12の両横に位置するガイド片18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し、ボルト29を中心とするアームB1の回転を阻止する。
【0022】
【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にアームB1の支持杆取付部B12における乗載面24を乗せ、支持杆取付部B12を受面16に沿ってずらして支持杆取付部B12の端部を浮上阻止片13の下に差し込めば、アームB1を受部材B22に仮止め状態に出来る特長がある。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。
更に上記の如き仮止め状態にする為に支持杆取付部B12の端部を浮上阻止片13の下に差し込む場合、受面16をガイド面として利用すると共に、その受面16の両横にあるガイド片18により支持杆取付部B12を案内することにより、支持杆取付部B12を確実に浮上阻止片13の下に向けて進行させられる特長がある。このことは、上記受面16及びガイド片18に沿って支持杆取付部B12をすうーっと移動させるのみの非常に容易な操作でもって、確実に上記仮止め状態を達成させることが出来る作業上の効果がある。

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. Further, the tightening force of the bolt 29 can be made to function sufficiently for the purpose of fixing the support rod mounting portion B12 to the receiving member B22. Reference numeral 32 denotes a through hole for passing the shaft portion 29b of the bolt 29. Reference numeral 33 denotes a means for preventing the bolt 29 from dropping out of the through hole 27 of the arm B1. In this example, the inner peripheral surface of the through hole 32 is pressed against the tip of the thread in the shaft portion 29b of the bolt 29. This prevents the bolt 29 from falling off. Reference numeral 34 denotes a slit provided to facilitate elastic deformation of the spacer 31, that is, elastic deformation for pressing the inner peripheral surface 33 against the bolt 29.
[0013]
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 of the upper wall B12a, and inserts the shaft portion 29b to a position where the shaft portion 29b does not protrude from the through hole 27 of the lower wall B12b. Assembly is performed up to this state.
[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. With one arm B1 held in hand, the mounting surface 24 is placed on the receiving surface 16 of one receiving member B22 as shown in FIG. In this state, the guide pieces 18 of the receiving member B22 are located on both sides of the guided portion 26 of the support rod mounting portion B12. Next, the arm B1 is shifted toward the main body B21 along the receiving surface 16 while being guided by the guide pieces 18 on both sides. When the end surface 25 comes into contact with the receiving surface 12, the locked portion 28 at the end of the support rod mounting portion B12 enters below the floating prevention piece 13, as shown in FIG. It is in a state of facing the part 28.
[0017]
As described above, when the locked portion 28 enters under the floating prevention piece 13, the arm B1 is temporarily fixed to the receiving member B22. 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. The operation will be described. In a state where the support rod mounting portion B12 of the arm B1 is placed on the receiving surface 16 as described above, the arm B1 is heavy on the tip side where the antenna C is attached. On the other hand, the support rod mounting portion B12 tends to rise using the tip of the receiving surface 16 as a fulcrum of the lever. However, the lifting prevention piece 13 facing the locked portion 28 prevents the support rod mounting portion B12 from lifting. In this way, the arm B1 is held in the temporarily fixed state.
[0018]
Further, when the support rod mounting portion B12 is temporarily fixed as described above, the left and right sides of the support rod mounting portion B12 are regulated in the left and right direction by the two guide pieces 18, and the end surface 25 comes into contact with the receiving surface 12 to move back and forth. Since the position is regulated in the direction, the support rod mounting portion B12 is accurately positioned with respect to the receiving member B22, and the through hole 27 of the lower wall B12b is in a state of being overlapped with the screw hole 17 exactly.
[0019]
After the temporary fixing state, the support rod mounting portion B12 is fully 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.
[0020]
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.
[0021]
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 guide pieces 18 located on both sides of the support rod mounting portion B12 become one of the fixing members of the arm B1 with respect to the receiving member B22. And stops the rotation of the arm B1 about the bolt 29.
[0022]
【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 of the support rod mounting portion B12 of the arm B1 is placed on the receiving surface 16, and the support rod mounting portion B12 is shifted along the receiving surface 16 so that the end of the support rod mounting portion B12 is moved. The arm B1 can be temporarily fixed to the receiving member B22 by inserting the portion under the floating prevention piece 13. 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.
Further, when the end of the support rod mounting portion B12 is inserted under the floating prevention piece 13 in order to make the temporary fixing state as described above, the receiving surface 16 is used as a guide surface, and both sides of the receiving surface 16 are used. By guiding the support rod mounting portion B12 by the guide piece 18, there is a feature that the support rod mounting portion B12 can be surely advanced to below the floating prevention piece 13. This is a very easy operation of simply moving the supporting rod mounting portion B12 along the receiving surface 16 and the guide piece 18, and the work capable of reliably achieving the temporary fixing state. Has the above effect.
