Description

本発明は，アンテナ装置と壁面やアンテナマストなどの取り付け対象物との間に介設し，前記アンテナ装置を取り付け対象物に取り付けるためのアンテナ支持装置に関するものであり，詳しくは，簡単の構成で広範囲に方向調整が可能で，しかも，アンテナを多様な取付対象に取り付けることができるアンテナ支持装置に関する。
The present invention relates to an antenna support device that is interposed between an antenna device and an attachment object such as a wall surface or an antenna mast, and for attaching the antenna device to the attachment object. The present invention relates to an antenna support device capable of adjusting a direction in a wide range and capable of attaching an antenna to various attachment targets.

アナログ放送の完全停波に向けて，地上デジタル放送を受信するための改修工事が，本格的に進められているなかで，地上デジタル放送を受信するためのＵＨＦアンテナは，従来からあるエレメント素子から構成された長尺の八木・宇多アンテナだけでなく，小型であっても高性能なアンテナが求められるようになった。そして，そのアンテナの設置場所も，従来のような屋根上に設置するだけではなく，ベランダや壁面などの多様な設置場所に設置できるものが求められ，更には，住宅等の何れの場所に設置しても違和感がないように，意匠的にも全く新しいデザインのアンテナが求められている。
また，ＵＨＦアンテナの性能やデザインばかりでなく，当該アンテナを設置場所に取り付けるためのアンテナ支持金具も，多様な設置場所に簡単に取り付けができ，しかも，設置場所における受信環境に対応するため，例えば方位角を広範囲に調整できる調整機構を備えさせるなど，簡単な構成で，しかも高機能な金具が求められるようになった，
In the midst of full-scale renovation work for receiving terrestrial digital broadcasts toward the complete stoppage of analog broadcasts, UHF antennas for receiving terrestrial digital broadcasts are based on conventional element elements. In addition to the constructed long Yagi / Uta antenna, high-performance antennas are required even if they are small. And the installation location of the antenna is required not only to install on the roof as in the past, but also to be installed in various installation locations such as a veranda and a wall surface, and further to any location such as a house. Even so, there is a need for a completely new antenna design.
Also, not only the performance and design of UHF antennas, but also the antenna support brackets for mounting the antennas at the installation location can be easily installed at various installation locations, and in order to cope with the reception environment at the installation locations, for example, There is now a need for a metal fitting with a simple structure and high functionality, such as an adjustment mechanism that can adjust the azimuth angle over a wide range.

このようなアンテナ支持装置の取り付け例として，アンテナを壁面に取り付ける場合について考えてみる。壁面取付の場合，アンテナを設置する壁面と，受信する電波の到来方向との位置関係によっては，方向調整機構の調整範囲が狭いアンテナ支持金具では，アンテナを電波到来方向に最適に向けることができない問題が生じる。
一方，方位角調整範囲が広いアンテナ支持装置では次に示すような問題が生じる。つまり，当該支持装置に取り付けるアンテナの大きさ，形状によっては，方位角の調整の際にアンテナの側端部が壁面に当接してしまうので，それを避けるために，アンテナを壁面から離して取り付けなければならない。しかしながら，このようなアンテナと壁面との距離の増加が必要となれば，それに対応するために支持装置の突出寸法を大きくしなければならないことから，アンテナ支持装置が大型化し重量も重くなる。
また，上述のように突出寸法を長くすると，アンテナに加わる風圧等によって生じる大きな力のモーメントがアンテナ支持装置に加わるので，支持装置は更に強固な構成なものが求められる。
更に加えて，アンテナ支持装置に加わる力が大きくなれば，壁面への取り付け工事もより強度が求められ，設置の困難性が高くなるのである。
As an example of mounting such an antenna support device, consider the case of mounting an antenna on a wall surface. In the case of wall mounting, depending on the positional relationship between the wall where the antenna is installed and the direction of arrival of the received radio wave, the antenna support bracket with a narrow adjustment range of the direction adjustment mechanism cannot optimally point the antenna in the direction of radio wave arrival. Problems arise.
On the other hand, an antenna support device with a wide azimuth adjustment range has the following problems. In other words, depending on the size and shape of the antenna attached to the support device, the side end of the antenna may come into contact with the wall surface when adjusting the azimuth angle. There must be. However, if it is necessary to increase the distance between the antenna and the wall surface, the projecting dimension of the support device must be increased in order to cope with the increase in distance, which increases the size and weight of the antenna support device.
In addition, when the protruding dimension is lengthened as described above, a moment of a large force generated by wind pressure applied to the antenna is applied to the antenna support device, so that the support device is required to have a stronger structure.
In addition, if the force applied to the antenna support device is increased, the installation work on the wall surface is required to be stronger, and the difficulty of installation becomes higher.

上述した問題に対応するためのアンテナ支持装置の従来技術として，平面アンテナ用の取付金具について提案されているので説明する。この実施例は，平面アンテナパネル１の両端部を支持する一対の取付金具３，４を取付面２に固定し，この取付金具３，４には円弧状の溝からなるガイドレール５ａ，５ｂ，６ａ，６ｂを形成し，前記平面アンテナパネルの両端部には前記各ガイドレールに嵌入されてガイドレールに沿って移動される突起７ａ，８ａ，７ｂ，８ｂを形成したことを特徴としている。
この従来技術の説明図（第１図及び第２図）によれば，平面アンテナパネル１が取付面２に対して正対した状態（つまり，電波到来方向が取付面の正面側であるとき）では，平面アンテナパネル１が取付面２に対して低背な姿勢で取付金具３，４に収容され，図１及び第２図（ａ）のように右方向へ方位角の調整が必要な場合は，平面アンテナパネル１の一方側の側端部に備えさせた突起７ａ，８ａを回転軸として，平面アンテナパネル１の他方の側端部に備えさせた突起７ｂ，８ｂをガイドレール５ｂ，６ｂに沿って移動させることで行なわれる（左方向への調整が必要な場合は，第２図（ｂ）のように突起７ｂ，８ｂを回転軸とする）ので，この実施形態に係る方向調整構造よれば薄型化，小型化，軽量化が図れる。
（例えば，特許文献１参照）
A mounting antenna for a planar antenna has been proposed as a prior art of an antenna support device for coping with the above-described problem, and will be described. In this embodiment, a pair of mounting brackets 3 and 4 that support both ends of the flat antenna panel 1 are fixed to the mounting surface 2, and the mounting rails 3 and 4 have guide rails 5a, 5b, 6a and 6b are formed, and projections 7a, 8a, 7b and 8b are formed on both ends of the planar antenna panel so as to be fitted to the guide rails and moved along the guide rails.
According to the explanatory diagrams of the prior art (FIGS. 1 and 2), the planar antenna panel 1 faces the mounting surface 2 (that is, when the radio wave arrival direction is the front side of the mounting surface). In the case where the flat antenna panel 1 is accommodated in the mounting brackets 3 and 4 in a low profile with respect to the mounting surface 2, and the azimuth angle must be adjusted to the right as shown in FIGS. 1 and 2 (a).

ところがこの構成では，平面アンテナパネル１の両側端部に備えさせた突起７ａ，８ａと突起７ｂ，８ｂは，それぞれ回転軸として，または回転のガイド手段となるよう，前記ガイドレール５ａ，５ｂ，６ａ，６ｂに嵌入されているので，取付金具３，４の大きさ（特に横幅）は，平面アンテナパネル１の形状によって影響を受け，例えば利得を高くするために平面アンテナパネル１を大きくすると，それに伴い取付金具３，４も大きくなるといった問題があった。
また，この実施例による取付金具３，４は，上下に分離した構成であるので，平面アンテナパネル１のピッチに合わせて取り付ける必要があり，取付金具３，４の取付面２への取り付けは手間が係ると言った問題がある。
更に加えて，設置後のアンテナについて考えると，この実施例では上述したように，前記突起は回転軸の軸心としての手段の役割と，平面アンテナパネル１をガイドレール５ａ，５ｂ，６ａ，６ｂに沿わせて移動させるためのガイド手段の役割を有するものであるが，実質的には移動後の平面アンテナパネル１を，取付金具３，４に固定する固定手段としての役目を有するもので無ければならない。そうでないと，せっかく調整した平面アンテナパネル１の向きが，風などの影響によって維持できないからである。その為，この実施例では，方向調整後の平面アンテナパネル１を当該位置に固定するために，少なくとも上下２箇所（例えば７ｂ，８ｂ），確実に固定するには最大で上下４箇所（７ａ，８ａ，７ｂ，８ｂ）を固定する必要となることから，アンテナの固定のための手間が面倒であるという問題もあった。
そこで本願においては，上述したような従来技術の問題点を解決し，多様な取付対象に簡単にアンテナを取り付けることができるアンテナ支持装置を提供することを課題としてなされたものであり，

For example, if the planar antenna panel 1 is enlarged in order to increase the gain, Accordingly, there is a problem that the mounting brackets 3 and 4 are also large.
Further, since the mounting brackets 3 and 4 according to this embodiment are separated from each other in the vertical direction, it is necessary to mount them according to the pitch of the flat antenna panel 1, and the mounting of the mounting brackets 3 and 4 to the mounting surface 2 is troublesome. There is a problem that said.
In addition, when the antenna after installation is considered, in this embodiment, as described above, the protrusion serves as a center of the rotating shaft, and the planar antenna panel 1 is guided to the guide rails 5a, 5b, 6a, 6b. It has a role of a guide means for moving along the line, but it should substantially serve as a fixing means for fixing the flat antenna panel 1 after the movement to the mounting brackets 3 and 4. I must. Otherwise, the adjusted orientation of the flat antenna panel 1 cannot be maintained due to the influence of wind or the like. Therefore, in this embodiment, in order to fix the planar antenna panel 1 after the direction adjustment to the position, at least two places (for example, 7b and 8b) at the top and bottom, and four places (7a, Since it is necessary to fix 8a, 7b, 8b), there is also a problem that the trouble of fixing the antenna is troublesome.
Therefore, in the present application, an object of the present invention is to solve the problems of the prior art as described above and provide an antenna support device that can easily attach an antenna to various attachment targets.
An object of the present invention is to provide an antenna support device capable of adjusting the direction over a wide range with a simple configuration.

更に，本発明の実施形態の取付具２０は，少なくとも一方の当付片（この実施形態では下側の当付片２３ｂ）に，当該当付片２３ｂに対向するように設けられた突片であって，前記保持具１０から突設されている挟持片（この実施形態では挟持片１３ｂ）を，挿抜自在に挟み込むように形成された誘導片３０が備えられている。
図１及び図２に示されているように，前記誘導片３０は，その前面側に前記挟持片１３ｂを受け入れるだけの空間３０ａを形成するために，金属体からなる板体３１を階段状になるように段差３２を有した形状に成型されており，この段差３２より前面側にあって一段低く位置する圧接部３３と，段差３２より背面側にあって，前記圧接部３３より一段高い位置にある添付部３４からなる。そして，この誘導片３０は，前記下側当付片２３ｂの外面（図では下面）の背面（図の手前）側に，前記添付部３４を当て付けながら，前記挟持片１３ｂに形成された孔３６ａに対して，タッピングビス３６等を螺合することによって取り付けられる。
Furthermore, the fixture 20 of the embodiment of the present invention is a projecting piece provided on at least one abutting piece (the lower abutting piece 23b in this embodiment) so as to face the abutting piece 23b. There is provided a guide piece 30 formed so as to be able to insert and remove a holding piece (in this embodiment, holding piece 13b) protruding from the holding tool 10 so as to be inserted and removed.
As shown in FIG. 1 and FIG. 2, the guide piece 30 is formed by stepping a plate 31 made of a metal body in order to form a space 30a for receiving the holding piece 13b on the front side. The pressure contact portion 33 is formed in a shape having a step 32 so that it is located on the front side of the step 32 and is located one step lower than the step 32, and is located on the back side of the step 32 and is one step higher than the pressure contact portion 33. The attachment part 34 in FIG. The guide piece 30 has a hole formed in the sandwiching piece 13b while abutting the attachment portion 34 on the back surface (front side of the drawing) of the outer surface (lower surface in the drawing) of the lower contact piece 23b. It is attached to 36a by screwing a tapping screw 36 or the like.

加えて，前記誘導片３０の圧接部３３には，当該誘導片３０を前記挟持片２３ｂに取り付けたときに，前記連結支持具２９の軸心と同一軸心上に位置するように形成された孔であって，前記連結具４５を構成するボルト体４６の先端部が遊挿自在となるような内径を有した貫通孔３９ａが形成されている。更にこの実施例では，前記誘導片３０の外面（図では下面）側には，前記貫通孔３９ａの軸心と一致させるように，前記連結具４５を構成する部品である，内部に目ネジ４７ａが形成されたナット体４７が一体的に連設されている。
尚，本発明の実施形態では，誘導片３０に前記連結具４５のナット体４７を一体的に備えさせた例が示されているが，当該ナット体４７に変えて，誘導片３０に形成された前記貫通孔３９ａの内面に，前記ボルト体４６の雄ネジ部４６ａと螺合する雌ネジ部を形成しても良い。
In addition, the pressure contact portion 33 of the guide piece 30 is formed so as to be positioned on the same axis as the axis of the connection support 29 when the guide piece 30 is attached to the clamping piece 23b. A through hole 39a having an inner diameter is formed so that the tip of the bolt body 46 constituting the connector 45 can be freely inserted. Furthermore, in this embodiment, on the outer surface (lower surface in the figure) side of the guide piece 30 is an internal thread 47a that is a part constituting the connector 45 so as to coincide with the axis of the through hole 39a. The nut body 47 formed with is integrally connected.
In the embodiment of the present invention, an example in which the guide piece 30 is integrally provided with the nut body 47 of the connector 45 is shown. However, instead of the nut body 47, the guide piece 30 is formed on the guide piece 30. Further, a female screw portion that is screwed with the male screw portion 46a of the bolt body 46 may be formed on the inner surface of the through hole 39a.

ここで，前記誘導片３０について更に詳しく説明する。本発明の実施形態の誘導片３０は，図２（ａ）によく示されているように，取付具２０の一方の当付片２３ｂに取り付けられた状態で，前記挟持片１３ｂを受け入れる空間３０ａの開口部が，僅かに大きく開くように揺動自在に蝶着されている。具体的には，例えば前記タッピングビス３６を当付片２３ｂに形成された孔３６ａに完全に締め付けるのではなく，完全に締め付けられる手前，即ち，仮止めの状態にしておくことで実現できる。
このように，誘導片３０が揺動自在に取り付けられていることによって，前記取付具２０と前記保持具１０を組み付けるに当たっては，前記誘導片３０が図２（ａ）のように配設されている場合は，誘導片３０は重力によって自動的に下方に開いた状態にあり，当該誘導片３０の存在があっても，対向配置される前記当付片２３ｂと誘導片３０が形成する空間３０ａ内に，前記挟持片１３ｂを容易に受け入れることができ，組み付けの容易性を損なうことが無い。そして，前記取付具２０と前記保持具１０を組み付けた後に，前記ボルト体４６を前記ナット体４７に螺着して連結具４５を組み付ければ，前記誘導片３０が挟持片１３ｂ側に引き付けられ，当該挟持片１３ｂは当付片２３ｂと誘導片３０とで強固に挟持されることから，高信頼な方向調整構造を提供できる。
また，前記誘導片３０の存在によって，前記連結具４５のナット体４７を当該誘導片３０に一体的に備えさせることができ，前記連結具４５の組み付けにおいては，前記ボルト体４６を誘導片３０に備えられたナット体３０に螺合するだけで行なえることから，簡単且つ素早く組み付けることができる。
Here, the guide piece 30 will be described in more detail. As shown in FIG. 2A, the guide piece 30 according to the embodiment of the present invention is a space 30a for receiving the holding piece 13b in a state of being attached to one abutting piece 23b of the fixture 20. The opening is hinged so as to swing slightly so as to open slightly. Specifically, for example, the tapping screw 36 is not completely tightened into the hole 36a formed in the abutting piece 23b, but can be realized by being in a state before being completely tightened, that is, in a temporarily fixed state.
As described above, when the guide piece 30 is swingably attached, the guide piece 30 is arranged as shown in FIG. 2A when the fixture 20 and the holder 10 are assembled. When the guide piece 30 is in the state of being automatically opened downward by gravity, even if the guide piece 30 is present, the space 30a formed by the abutting piece 23b and the guide piece 30 that are arranged to face each other. The clamping piece 13b can be easily received inside, and the ease of assembly is not impaired. Then, after the mounting tool 20 and the holding tool 10 are assembled, if the bolt body 46 is screwed to the nut body 47 and the coupling tool 45 is assembled, the guide piece 30 is attracted to the clamping piece 13b side. Since the clamping piece 13b is firmly clamped between the contact piece 23b and the guide piece 30, a highly reliable direction adjusting structure can be provided.
Further, due to the presence of the guide piece 30, the nut body 47 of the connector 45 can be provided integrally with the guide piece 30, and when the connector 45 is assembled, the bolt body 46 is connected to the guide piece 30. Since it can be performed simply by screwing into the nut body 30 provided in the above, it can be easily and quickly assembled.

このように構成された保持具１０，取付具３０及び連結具４５の組み付け手順について図２，図３を用いて説明する。保持具１０と取付具２０の組み付けは，前記取付具２０の当付片２３ａ，２３ｂが，前記取付具１０の挟持片１３ａ，１３ｂに間に挟み込まれように，前記スライド溝１４ａ，１４ｂの軸線と，前記連結支持部２９の軸心とを一致するまで，摺動接触させつつ挿着する。この時，本発明の実施形態では，前記当付片２３ａ，２３ｂの外面と，前記挟持片１３ａ，１３ｂに形成された***部１５ａ，１５ｂの先端部とが，丁度接触するような間隔に配列されていることが望ましい。
このように本願発明の実施形態によれば，当付片２３ａ，２３ｂと***部１５ａ，１５ｂの先端部が接触しながら挿着する構成としたことによって，相互に接触する部分の面積が少なくでき，その結果，当付片２３と挟持片１３との摩擦力を小さくすることができるので，保持具１０と取付具２０の組み付けが容易にできるようになる。また，挟持片１３ａ，１３ｂの間隔が寸法公差等によって僅かに狭くなってしまって，***部１５ａ，１５ｂと，当付片２３ａ，２３ｂの先端部が当接してしまうような場合でも，保持具１０と取付具２０を相互に押し付ければ，前記***部１５ａ，１５ｂが前記当付片２３ａ，２３ｂの先端部を容易に乗り越え，前記挟持片１３ａ，１３ｂを僅かに外方向に撓ませながら挿着できることから，前記保持具１０と取付具２０の組み付けの容易性を損なうことは無い。
A procedure for assembling the holder 10, the fixture 30, and the coupler 45 configured as described above will be described with reference to FIGS. The holder 10 and the fixture 20 are assembled in such a manner that the contact pieces 23a and 23b of the fixture 20 are sandwiched between the clamping pieces 13a and 13b of the fixture 10 and the axis of the slide grooves 14a and 14b. And is inserted while being in sliding contact until the axial center of the connection support portion 29 coincides. At this time, in the embodiment of the present invention, the outer surfaces of the abutting pieces 23a and 23b and the tips of the raised portions 15a and 15b formed on the sandwiching pieces 13a and 13b are arranged at intervals so as to be in contact with each other. It is desirable that
As described above, according to the embodiment of the present invention, since the contact pieces 23a and 23b and the tip portions of the raised portions 15a and 15b are inserted in contact with each other, the area of the portions that are in contact with each other can be reduced. As a result, since the frictional force between the abutting piece 23 and the clamping piece 13 can be reduced, the holder 10 and the fixture 20 can be easily assembled. Even when the gap between the sandwiching pieces 13a and 13b is slightly narrowed due to dimensional tolerances or the like, the raised portions 15a and 15b and the tip portions of the contact pieces 23a and 23b come into contact with each other. 10 and fixture 20 are pressed against each other, the raised portions 15a and 15b can easily get over the tips of the abutting pieces 23a and 23b, and be inserted while slightly bending the holding pieces 13a and 13b outward. Since it can be worn, the ease of assembly of the holder 10 and the fixture 20 is not impaired.

次に，スライド溝１４の軸線と連結支持部２９の軸心が略一致したなら，前記ボルト体４６を，上側の当付片１３ａに形成された前記スライド溝１４ａ側から，連結支持部２９の挿通孔２９ａに挿入する。そして挿入が完了したなら，ボルト体４６の先端部に形成された雄ネジ部４６ａを，誘導片２０に一体的に備えられているナット体４７の雌ネジ部４７ａに対して螺合することによって，取付具３０及び連結具４５の組み付けが完了し，図３（ａ）に示すように本発明のアンテナ支持装置５０が完成する。
更に，保持具１０と取付具２０を緊締するときは，前記連結具４５をしっかりと締め付ければ，前記挟持片１３ａ，１３ｂ及び誘導片３０がそれぞれ当付片２３ａ，２３ｂに押圧されることで確実にできる。しかも，上側の当付片２３ａと下側当付片２３ｂの間には，前記ボルト体４６と軸心を一致させるように，連結支持部２９が設けられているので，連結具４５によって挟持片１３ａ，１３ｂ及び誘導片３０が当付片２３ａ，２３ｂをしっかりと押圧しても，当付片２３ａと当付片２３ｂの間隔は所定の寸法を保つため，時間が経過しても連結具４５の締め付け具合が緩むことは無い。
尚，図２及び図３には，前記挟持金具４０の存在が示されていないが，予め取付具１０に対して組み付けておいてアンテナ支持装置５０を構成してもよいし，付属品として備えさせるようにしても良い。
Next, when the axis of the slide groove 14 and the axis of the connection support portion 29 substantially coincide, the bolt body 46 is moved from the slide groove 14a side formed on the upper contact piece 13a to the connection support portion 29. Insert into the insertion hole 29a. When the insertion is completed, the male screw portion 46a formed at the tip of the bolt body 46 is screwed into the female screw portion 47a of the nut body 47 provided integrally with the guide piece 20. Assembling of the fixture 30 and the connector 45 is completed, and the antenna support device 50 of the present invention is completed as shown in FIG.
Further, when the holder 10 and the fixture 20 are tightened, the clamping pieces 13a and 13b and the guide piece 30 are pressed against the contact pieces 23a and 23b, respectively, if the connecting tool 45 is firmly tightened. You can be sure. In addition, since the connection support portion 29 is provided between the upper contact piece 23a and the lower contact piece 23b so that the bolt body 46 and the shaft center coincide with each other, Even if 13a, 13b and the guide piece 30 firmly press the contact pieces 23a, 23b, the distance between the contact piece 23a and the contact piece 23b maintains a predetermined size, so that the connector 45 can be used even if time passes. The tightening condition of will not loosen.
2 and 3 do not show the presence of the holding metal fitting 40, but the antenna support device 50 may be configured by being assembled to the fixture 10 in advance, or provided as an accessory. You may make it let it.

ここで図３（ｂ）と（ｃ）を用いて，組み付けが完了したアンテナ支持装置５０の説明を行う。図３（ａ）は保持具１０と取付具２０を正対させたときのアンテナ支持装置５０を示した図であり，図３（ｃ）は本発明の取付具１０と保持具２０の連結状態の態様を説明するための上面図である。
本発明の実施形態では，前記保持具１０は，図３（ｃ）に良く示されているように，前記連結具４５のボルト体４６を回転軸として図の矢印Ｒのように揺動自在に回転させることができる。更に，本発明の実施形態では，保持具１０にスライド溝１４を備えたことによって，保持具１０はボルト体４６をガイド手段として，前記スライド溝１４の軸線に沿うように，前記スライド溝１４の長さの範囲内の任意の位置に，スライド（図の矢印Ｆ。図では上下方向）可能となり，当該任意の位置において揺動させることができる。
即ち，本発明に係るアンテナ支持装置５０は，アンテナ装置６０を取り付けるための保持具１０が，前記ボルト体４６をガイド手段としてスライド可能に構成されていることによって，アンテナ装置６０の方位角の調整に際し，アンテナ装置６０の回転軸（即ち，ボルト体４６）の位置を，前記スライド溝１４の長さの範囲内の任意の位置で変えることができるように構成されているのである。
Here, the antenna support device 50 that has been assembled will be described with reference to FIGS. FIG. 3A is a view showing the antenna support device 50 when the holder 10 and the fixture 20 are directly opposed, and FIG. 3C is a connection state of the fixture 10 and the holder 20 of the present invention. It is a top view for demonstrating the aspect of.
In the embodiment of the present invention, as shown in FIG. 3 (c), the holder 10 is swingable as indicated by an arrow R in the figure with the bolt body 46 of the connector 45 as a rotation axis. Can be rotated. Furthermore, in the embodiment of the present invention, since the holder 10 is provided with the slide groove 14, the holder 10 uses the bolt body 46 as a guide means and the slide groove 14 extends along the axis of the slide groove 14. Slide (arrow F in the figure, vertical direction in the figure) can be performed at any position within the length range, and can be swung at the arbitrary position.
In other words, the antenna support device 50 according to the present invention adjusts the azimuth angle of the antenna device 60 because the holder 10 for mounting the antenna device 60 is configured to be slidable using the bolt body 46 as a guide means. At this time, the position of the rotating shaft (that is, the bolt body 46) of the antenna device 60 can be changed at an arbitrary position within the range of the length of the slide groove 14.

このように構成されたアンテナ支持装置５０の具体的な使用例について，図４を用いて説明する。この図４は本発明のアンテナ支持装置５０の取り付け対象の一つである壁面１００に，本発明のアンテナ支持装置５０を介してアンテナ装置６０を取り付けた状態を示す上面図である（つまり，図４の上下方向が水平線であり，図の手前側から奥行き方向が鉛直方向を示している。）。尚，この図４において，図の手前側と奥行き方向を水平線，図の上下方向を鉛直方向とすれば，図４は壁面１００に取り付けられた状態を示す側面図に置き換えることができる。
A specific use example of the antenna support device 50 configured as described above will be described with reference to FIG. FIG. 4 is a top view showing a state in which the antenna device 60 is attached to the wall surface 100, which is one of the attachment targets of the antenna support device 50 of the present invention, via the antenna support device 50 of the present invention (that is, FIG. The vertical direction of 4 is a horizontal line, and the depth direction from the near side of the figure indicates the vertical direction. In FIG. 4, if the front side and the depth direction in the figure are horizontal lines and the vertical direction in the figure is a vertical direction, FIG. 4 can be replaced with a side view showing a state attached to the wall surface 100.

図４（ａ）は，電波到来方向が取付面１００の正面（具体的には，方位角が略０°）である場合の設置例を示しており，保持具１０の回転軸であるボルト体４６，即ち，アンテナ装置６０の回転軸が，スライド溝１４の略中央に位置している例が示されている。尚，前記保持体１０をスライドさせて，スライド溝１４の長さの範囲内の何れの位置に回転軸を決めても良い。
次に図４（ｂ）は，電波到来方向が図の上側（即ち，取付面１００から見て左側方向）である場合の設置例を示しており，アンテナ装置６０の回転軸であるボルト体４６の位置はスライド溝１４の図における左斜め上（即ち，取付面１００から見て左端）に位置する例が示されている。この実施例でも，スライド溝１４の長さの範囲内の何れの位置に回転軸を決めても良い。
FIG. 4A shows an installation example when the direction of arrival of radio waves is the front of the mounting surface 100 (specifically, the azimuth angle is approximately 0 °). 46, that is, an example in which the rotating shaft of the antenna device 60 is located at the approximate center of the slide groove 14 is shown. The holding body 10 may be slid to determine the rotation axis at any position within the range of the length of the slide groove 14.
Next, FIG. 4B shows an installation example in the case where the radio wave arrival direction is the upper side of the drawing (that is, the left side as viewed from the mounting surface 100), and the bolt body 46 which is the rotation axis of the antenna device 60 is shown. An example is shown in which the position is located obliquely above and to the left of the slide groove 14 (that is, at the left end when viewed from the mounting surface 100). Also in this embodiment, the rotation axis may be determined at any position within the range of the length of the slide groove 14.

ここで，本発明に係るアンテナ支持装置５０の作用について図５を用いて説明する。図５も図４と同様に上面から見た図である。この図５（ａ）において矢印Ａ°で示されているのが，保持体１０を，ボルト体４６をガイド手段としてスライドさせることによって，保持体１０（即ち，アンテナ装置６０）の回転軸がスライド溝１４の左端側に位置するようにした場合の，アンテナ支持装置５０の方位角調整範囲の左側半分の可変領域である（左右方向には±Ａ°の可変範囲となる）。これに対して，図５（ｂ）で示されている例は，ボルト体４６が保持具１０の中央部にあって，その位置を移動させることができないアンテナ支持装置１５０の例を示しており，図中において矢印Ｂ°で示されているのが，アンテナ支持装置１５０の方位角調整範囲の左側半分の可動領域である（左右方向には±Ｂ°の可変範囲となる）。
Here, the operation of the antenna support device 50 according to the present invention will be described with reference to FIG. FIG. 5 is also a view as seen from the top like FIG. In FIG. 5A, the arrow A ° indicates that the holding body 10 is slid using the bolt body 46 as a guide means, so that the rotation shaft of the holding body 10 (that is, the antenna device 60) is slid. This is a variable region on the left half of the azimuth angle adjustment range of the antenna support device 50 when it is positioned on the left end side of the groove 14 (± A ° variable range in the left-right direction). On the other hand, the example shown in FIG. 5B shows an example of the antenna support device 150 in which the bolt body 46 is in the center of the holder 10 and the position thereof cannot be moved. In the figure, the arrow B ° indicates the movable region in the left half of the azimuth angle adjustment range of the antenna support device 150 (with a ± B ° variable range in the left-right direction).

この例から分かるように，回転軸であるボルト体４６の位置が固定されているアンテナ支持装置１５０に対して，方位角の調整範囲を広くしようとすると，アンテナ装置６０を傾けたときに，アンテナの側端部が取付面に対して重合しないよう，アンテナ装置６０の横幅に応じて，壁面１００からボルト体４６までの距離を増して行く必要がある。具体的には図５（ｂ）に良く示されているように，回転軸が固定されたアンテナ支持装置１５０を用いて，本願発明のアンテナ支持装置５０と同等の方位角調整範囲（略±Ａ°）を持たせようとすると，壁面１００とボルト体４６の距離は，本発明のアンテナ支持装置５０の距離Ｌ１より，更にＬ２だけ距離を増した位置４６´まで前方に突出させる必要が生じる。尚，図５（ｂ）に示されている実施例によれば，その距離（Ｌ１＋Ｌ２）は距離Ｌ１の略１．４５だけ長くなる。
つまり，この実施例のように壁面１００と回転軸であるボルト体４６との距離の増加を認めると，アンテナ支持装置１５０の突出寸法が大きくなって重くなるし，また，アンテナ支持装置１５０の強度は，アンテナ装置６０に加わる風圧によって生じるモーメント力に耐え得る強度にしなければならないと言った問題が生じる。
更に加えて，アンテナ支持装置１５０に加わる力が大きくなれば，壁面１００への取り付け工事もより強度が求められ，壁面１００への設置の困難性が高くなると言った問題が考えられるのである。
As can be seen from this example, when the antenna device 60 is tilted when the antenna device 60 is tilted, the azimuth angle adjustment range is widened with respect to the antenna support device 150 in which the position of the bolt body 46 serving as the rotation shaft is fixed. It is necessary to increase the distance from the wall surface 100 to the bolt body 46 according to the lateral width of the antenna device 60 so that the side end portions of the antenna device 60 do not overlap with the mounting surface. Specifically, as well shown in FIG. 5B, an azimuth adjustment range (approximately ± A) equivalent to that of the antenna support device 50 of the present invention is used by using the antenna support device 150 having a fixed rotation axis. If it is desired to have the angle (°), the distance between the wall surface 100 and the bolt body 46 needs to protrude forward to a position 46 'which is further increased by L2 from the distance L1 of the antenna support device 50 of the present invention. According to the embodiment shown in FIG. 5B, the distance (L1 + L2) is increased by approximately 1.45 of the distance L1.
That is, if the increase in the distance between the wall surface 100 and the bolt body 46 that is the rotating shaft is recognized as in this embodiment, the projecting dimension of the antenna support device 150 becomes large and heavy, and the strength of the antenna support device 150 is increased. Has a problem that it must be strong enough to withstand the moment force generated by the wind pressure applied to the antenna device 60.
In addition, if the force applied to the antenna support device 150 is increased, the installation work on the wall surface 100 is required to have higher strength, and there is a problem that the installation on the wall surface 100 becomes more difficult.

ところが，本願発明のアンテナ支持装置５０によれば，保持具１０が前記ボルト体４６をガイド手段として，前記スライド溝１４に沿うように移動可能にしたことによって，保持具１０の回転軸（つまり，アンテナ装置６０の回転軸）の位置を変えることができることから，例えば，図５（ａ）のように左側に方位角の調整を行なう場合について考えてみると，アンテナ装置６０の側端部が壁面１００と重合しないように，保持体１０つまりはアンテナ装置６０を，壁面１００から図の右斜め下方向にスライドさせながら，スライド溝１４の左端側に，ボルト体４６を位置させることで，壁面１００からボルト体４６の距離を増加させることなく，更に広い方向調整範囲を得ることができるのである。具体的には，図５に示した実施例では，壁面１００とボルト体４６の距離がＬ１で，アンテナ装置６０の大きさも同じである条件では，アンテナ支持装置１５０の方位角調整範囲（±Ｂ°）は略±４０°であったのに対して，本願発明のアンテナ支持装置５０の方位角調整範囲（±Ａ°）は略±６０°となり，調整範囲が約１．５倍に広くすることができる。
However, according to the antenna support device 50 of the present invention, the holder 10 can be moved along the slide groove 14 using the bolt body 46 as a guide means. Since the position of the rotation axis of the antenna device 60 can be changed, for example, in the case of adjusting the azimuth angle on the left side as shown in FIG. In order to prevent the holding body 10, that is, the antenna device 60 from sliding on the wall 100 in the diagonally downward direction in the figure, the bolt body 46 is positioned on the left end side of the slide groove 14 so as not to overlap with the wall 100. Thus, a wider direction adjustment range can be obtained without increasing the distance of the bolt body 46. Specifically, in the embodiment shown in FIG. 5, the azimuth adjustment range (± B) of the antenna support device 150 under the condition that the distance between the wall surface 100 and the bolt body 46 is L1 and the size of the antenna device 60 is the same. Is approximately ± 40 °, whereas the azimuth angle adjustment range (± A °) of the antenna support device 50 of the present invention is approximately ± 60 °, and the adjustment range is widened by about 1.5 times. be able to.

以上のように，本発明のアンテナ支持装置５０によれば，簡単な構成でもって，常時は壁面１００に対して低背で取り付けることができ，しかも，アンテナ装置６０の方位角の調整が必要なときは，壁面１００とアンテナ装置６０の回転軸（ボルト体４６）との距離Ｌ１の増加をすることなしに，広い方位角調整範囲を有するように構成できるのである。
しかもこのように，広い方位角調整範囲を有するように構成しても，壁面１００から回転軸であるボルト体４６までの距離を増して行く必要がないので，アンテナ支持装置５０の突出寸法が小さくでき，延いてはアンテナ装置の小型化，軽量化が図れると言った利点がある。
また，アンテナ支持装置５０の突出寸法が小さくなれば，アンテナ装置６０に加わる風圧によって生じるモーメント力を小さくできるので，アンテナ支持装置５０の構成を簡素化することができ，コストが安価にできる。
更に，アンテナ支持装置５０に加わる力が抑えられることから，壁面１００への取り付け工事がより簡単に行えるようになるし，これに伴い工数の低減が図れる。
As described above, according to the antenna support device 50 of the present invention, the antenna support device 50 can be always attached with a low profile to the wall surface 100 with a simple configuration, and the azimuth angle of the antenna device 60 needs to be adjusted. In some cases, a wide azimuth adjustment range can be provided without increasing the distance L1 between the wall surface 100 and the rotating shaft (bolt body 46) of the antenna device 60.
Moreover, even if it is configured to have a wide azimuth adjustment range in this way, it is not necessary to increase the distance from the wall surface 100 to the bolt body 46 that is the rotating shaft, so the projecting dimension of the antenna support device 50 is small. As a result, there is an advantage that the antenna device can be reduced in size and weight.
Further, if the projecting dimension of the antenna support device 50 is reduced, the moment force generated by the wind pressure applied to the antenna device 60 can be reduced, so that the configuration of the antenna support device 50 can be simplified and the cost can be reduced.
Furthermore, since the force applied to the antenna support device 50 is suppressed, the installation work to the wall surface 100 can be performed more easily, and the number of man-hours can be reduced accordingly.

尚，本発明は，以下に示すように本発明の趣旨を逸脱しない範囲で各部の構成を適宜に変更して実施することも可能である。
上記実施例は，図１のように各構成要素が配置された状態，具体的には，水平偏波で送信されてくる地上デジタル放送の電波を受信する場合のアンテナ支持装置について説明したが，地上デジタル放送の電波が垂直偏波で送信されてくる場合には，図４から図６で示されている図の手前側と奥行き方向を水平線，図の上下方向を鉛直方向と読み替えれば，図４から図６の図は壁面１００や手すり１０１に取り付けられた状態を示す側面図に置き換えることができる。
It should be noted that the present invention can be implemented by appropriately changing the configuration of each part without departing from the spirit of the present invention as described below.
