Description

本発明は、平面アンテナ等のアンテナの仰角を調整して支柱に取付けるアンテナ用チルト金具に関する。 The present invention relates to an antenna tilt bracket that is attached to a support column by adjusting the elevation angle of an antenna such as a planar antenna.

例えば、アンテナ支持体の上部と下部に所定の間隔をあけて下部支持部材及び上部支持部材を取付け、下部支持部材には回動支持機構を設けて、アンテナの下部側を回動可能に支持する一方、上部支持部材には仰角調整機構を設け、アンテナ上部を支持し、電柱等の支柱に対するアンテナの仰角を調整するようにしたアンテナ用チルト金具がある（例えば、特許文献１参照。）。 For example, a lower support member and an upper support member are attached to the upper and lower portions of the antenna support body with a predetermined interval, and a rotation support mechanism is provided on the lower support member so that the lower side of the antenna is rotatably supported.

しかし、上記アンテナ用チルト金具では、仰角調整機構がシャフトを挟持する位置を変えることにより、アンテナの仰角を無段階で調整していたため、小さな所定角度毎に仰角を精度良く設定することが困難であると共に、広角度な仰角を設定するには長いシャフトが必要になり、金具が大型化する、という課題もある。 However, in the antenna tilt bracket, the elevation angle adjustment mechanism changes the position where the shaft is clamped to adjust the elevation angle of the antenna steplessly, so it is difficult to accurately set the elevation angle for each small predetermined angle. In addition, there is a problem that a long shaft is required to set a wide angle of elevation, and the metal fitting is enlarged.

そこで、本発明は、金具が大型化せずに、所定角度毎の仰角を精度良く設定することができる、アンテナ用チルト金具を提供することを目的とする。 Therefore, an object of the present invention is to provide an antenna tilt bracket that can accurately set the elevation angle for each predetermined angle without increasing the size of the bracket.

さらに、前記調整部金具と前記基部金具の組を前記上側金具または前記下側金具として使用する一方、前記回転部金具と前記基部金具の組を前記下側金具または前記上側金具として使用する、アンテナ用チルト金具であることが望ましい。 In order to solve the above-described problems, an antenna tilt bracket according to the present invention is provided as an upper bracket or a lower bracket at at least one of upper and lower two positions with a predetermined interval in a pole such as a utility pole, and An antenna tilt bracket that adjusts and mounts an elevation angle by a predetermined angle, and includes an adjustment bracket and a base bracket. A plurality of angle setting bolt holes for each angle are arranged in an oblique direction, and the center-to-center distance in the elevation angle adjusting direction between the angle setting bolt holes adjacent to the oblique direction is smaller than the diameter of the angle setting bolt hole. On the other hand, when the base metal fitting is connected to the adjustment metal fitting, the base metal fitting comes into contact with the plurality of angle setting bolt holes formed in the adjustment metal fitting.

以下、本発明に係るアンテナ用チルト金具の実施形態について説明する。
実施形態． Hereinafter, embodiments of a tilt fitting for an antenna according to the present invention will be described.
Embodiment.

図１（ａ），（ｂ）は、それぞれ本発明に係るアンテナ用チルト金具の実施形態の使用態様の一例を示す全体図である。 FIGS. 1A and 1B are overall views showing examples of usage modes of the embodiment of the antenna tilt bracket according to the present invention, respectively.

図１（ａ），（ｂ）に示すように、本発明に係るアンテナ用チルト金具を上部金具Ｕおよび下部金具Ｄとして用いて、平面アンテナ等のアンテナ１裏面の左右上下２箇所のアンテナ取付け部１１ａ，１１ｂ、１２ａ，１２ｂに取り付けている。 As shown in FIGS. 1 (a) and 1 (b), antenna mounting brackets according to the present invention are used as an upper mounting bracket U and a lower mounting bracket D, and antenna mounting portions at two locations on the left and right and up and down on the back surface of the antenna 1 such as a planar antenna. It is attached to 11a, 11b, 12a, 12b.

ここで、図１（ａ）は、アンテナ１側に上部金具Ｕとしてアンテナ１の仰角を調整する調整部金具２を設ける一方、下部金具Ｄとして仰角調整の回転中心となる回転部金具３を設けた場合を示しており、図１（ｂ）は、これとは逆に、アンテナ１側に上部金具Ｕとして仰角調整の回転中心となる回転部金具３を設ける一方、下部金具Ｄとしてアンテナ１の角度を調整する調整部金具２を設けた場合を示している。つまり、図１（ａ），（ｂ）では、上下のアンテナ支持箇所で、調整部金具２と、回転部金具３とを入れ替えている。 Here, in FIG. 1A, an adjustment fitting 2 for adjusting the elevation angle of the antenna 1 is provided as an upper fitting U on the antenna 1 side, while a rotation fitting 3 serving as a rotation center for elevation adjustment is provided as a lower fitting D. On the contrary, FIG. 1B shows a case where the rotating bracket 3 serving as the center of rotation for elevation angle adjustment is provided on the antenna 1 side as the upper bracket U, while the antenna 1 as the lower bracket D is provided. The case where the adjustment part metal fitting 2 which adjusts an angle is shown is shown. That is, in FIG. 1 (a), (b), the adjustment part metal fitting 2 and the rotation part metal fitting 3 are replaced by the upper and lower antenna support location.

そして、図１（ａ），（ｂ）の場合、共に、電柱等の支柱側には、調整部金具２および回転部金具３と連結される同一の基部金具４が設けられている。 1 (a) and 1 (b), the same base metal fitting 4 connected to the adjustment metal fitting 2 and the rotating metal fitting 3 is provided on the side of the support pole such as a utility pole.

したがって、上部金具Ｕおよび下部金具Ｄ側として支柱側には、同一の基部金具４が使用できるので、この点で、従来の場合より部品点数を削減することができる。 Therefore, since the same base metal fitting 4 can be used on the support column side as the upper metal fitting U and the lower metal fitting D side, the number of parts can be reduced in this respect as compared with the conventional case.

なお、基部金具４と、図示しない支柱との間には、Ｍ座５と、バンド６とが設けられており、これらにより、支柱に固定される。 An M seat 5 and a band 6 are provided between the base metal fitting 4 and a post (not shown), and are fixed to the post by these.

また、本実施形態では、アンテナ１として、平面アンテナを使用しているが、これに限るものではない。 In this embodiment, a planar antenna is used as the antenna 1, but the present invention is not limited to this.

図２（ａ）〜（ｄ）は、それぞれ図１に示す実施形態の調整部金具２の一例を示す図である。 FIGS. 2A to 2D are views showing an example of the adjustment fitting 2 of the embodiment shown in FIG.

具体的には、図２（ａ）は、調整部金具２の外観を示す斜視図、同（ｂ）は、調整部金具２の平面図、同（ｃ）は、同（ｂ）調整部金具２の左側面図、同（ｄ）は、調整部金具２の後面図である。なお、調整部金具２を右側面と、調整部金具２を前面図は、それぞれ、図２（ｃ），（ｄ）と同じであるので、省略する。 Specifically, FIG. 2A is a perspective view showing the external appearance of the adjustment fitting 2, FIG. 2B is a plan view of the adjustment fitting 2, and FIG. 2C is the adjustment fitting 2. 2 is a left side view of FIG. 2, and FIG. In addition, since the adjustment part metal fitting 2 is the right side and the adjustment part metal fitting 2 is a front view which is the same as FIGS.

図２から明らかなように、調整部金具２は、断面コ字状の金具であり、上面２１と、両側面２２ａ、２２ｂとを有しており、基部金具４と連結する。 As is clear from FIG. 2, the adjustment member 2 is a metal having a U-shaped cross section, and has an upper surface 21 and both side surfaces 22 a and 22 b and is connected to the base metal 4.

調整部金具２の上面２１には、アンテナ１の仰角を０度〜２０度の範囲で設定するため、複数（ここでは、２０個とする。）の角度設定ボルト孔２１ａ〜２１ｕが、０度〜２０度の間、１度毎にそれぞれに対応して、図上Ａ方向の斜め方向に配列し、かつ、当該斜め方向に隣接する角度設定ボルト孔２１ａ〜２１ｕ間の図上Ｂ方向の仰角調整方向の中心間距離が当該角度設定ボルト孔の直径より小さく形成されている。 In order to set the elevation angle of the antenna 1 in the range of 0 degrees to 20 degrees, a plurality of (here, 20) angle setting bolt holes 21 a to 21 u are formed on the upper surface 21 of the adjustment fitting 2 at 0 degrees. The angle of elevation in the B direction in the figure between the angle setting bolt holes 21a to 21u arranged in an oblique direction in the A direction on the figure and adjacent to the oblique direction corresponding to each degree of ~ 20 degrees. The distance between the centers in the adjustment direction is smaller than the diameter of the angle setting bolt hole.

具体的には、角度設定ボルト孔２１ａが０度、角度設定ボルト孔２１ｂが１度、角度設定ボルト孔２１ｃが２度、・・・、角度設定ボルト孔２１ｓが１８度、角度設定ボルト孔２１ｔが１９度、角度設定ボルト孔２１ｕが２０度、というように図上Ａ方向に５列配列して形成されている。なお、角度設定ボルト孔２１ａ〜２１ｕの所定角度の１度毎は、一例であり、０．５度でも、あるいは２度、３度でも勿論良い。また、０度〜２０度の範囲も一例であり、０度〜１０度でも、０度〜３０度、０度〜４０度の範囲でも勿論よい。 Specifically, the angle setting bolt hole 21a is 0 degree, the angle setting bolt hole 21b is 1 degree, the angle setting bolt hole 21c is 2 degrees,..., The angle setting bolt hole 21s is 18 degrees, and the angle setting bolt hole 21t. Is 19 degrees, and the angle setting bolt holes 21u are 20 degrees. In addition, every 1 degree | times of the predetermined angle of the angle setting bolt holes 21a-21u is an example, and of course, 0.5 degree | times or 2 degree | times and 3 degree | times may be sufficient. Moreover, the range of 0 degree to 20 degrees is also an example, and may be in the range of 0 degree to 10 degrees, 0 degree to 30 degrees, or 0 degree to 40 degrees.

そして、本実施形態では、調整部金具２の上面２１の後端（図上右側端）から、最初の０度の角度設定ボルト孔２１ａまでの距離Ｍと、回転部金具３の上面３１の後端から回転部金具３の上面３１に形成された連結ボルト孔３１ａまでの距離Ｎ（図４参照）とは、同一にしている。これにより、上下２箇所のいずれか一方の位置で、調整部金具２がその角度設定ボルト孔２１ａにより基部金具４と連結し、かつ、他方の位置で、回転部金具３がその連結ボルト孔３１ａまで基部金具４と連結した場合には、支柱に対するアンテナ１の仰角は、０度になる。 In the present embodiment, the distance M from the rear end (right end in the figure) of the upper surface 21 of the adjustment member 2 to the first 0 degree angle setting bolt hole 21a and the rear surface 31 of the rotating member 3 The distance N (see FIG. 4) from the end to the connecting bolt hole 31a formed on the upper surface 31 of the rotating member 3 is the same. As a result, the adjustment fitting 2 is connected to the base fitting 4 by the angle setting bolt hole 21a at one of the upper and lower two positions, and the rotating fitting 3 is connected to the connecting bolt hole 31a at the other position. In the case where the base metal fitting 4 is connected, the elevation angle of the antenna 1 with respect to the support is 0 degree.

そして、調整部金具２の両側面２２ａ，２２ｂには、後述する基部金具４側面の脱落防止ボルト孔と孔同士が出合い、脱落防止用ボルトが止められる図上水平方向の長孔である脱落防止ボルト長孔２２ａ１、２２ｂ１が形成されていると共に、アンテナ１裏面の上下２箇所に調整部金具２および回転部金具３の幅に合わせて設けられた左右のアンテナ取付け部１１ａ，１１ｂ（又は１２ａ，１２ｂ）の連結ボルト孔（図示せず）に出合う、図上垂直方向の長孔である垂直ボルト長孔２２ａ，２２ｂ２が形成されている Further, on both side surfaces 22a and 22b of the adjusting portion metal fitting 2, a drop-off prevention bolt hole on the side surface of the base metal fitting 4 described later comes into contact with each other, and a drop-out prevention which is a long hole in the horizontal direction in FIG. Bolt long holes 22a1 and 22b1 are formed, and left and right antenna mounting portions 11a and 11b (or 12a, 12a, and 12b) are provided at two positions on the back surface of the antenna 1 according to the widths of the adjustment fitting 2 and the rotation fitting 3. Vertical bolt long holes 22a and 22b2, which are long holes in the vertical direction in the figure, are formed to meet the connecting bolt holes (not shown) of 12b).
