Embodiments of a rod-shaped antenna mounting bracket according to the present invention will be described below with reference to the drawings.
The rod-shaped antenna mounting bracket according to the present invention is a rod-shaped antenna mounting bracket for mounting two or more rod-shaped antennas to a column, and has a diameter at the upper end of the column 2 as shown in FIGS. Two of the large-diameter rod-shaped antennas (hereinafter sometimes abbreviated as “large-diameter antennas”) 31 and the small-diameter rod-shaped antennas (hereinafter sometimes abbreviated as “small-diameter antennas”) 32 are attached. It is configured. That is, the rod-shaped antenna mounting bracket 1 fixes the long gripping plate 11, the support gripping plate 12, the large-diameter antenna gripping plates 13 and 13 and the small-diameter antenna gripping plates 14 and 14 each prepared. The large-diameter antenna 31 or the small-diameter antenna 32 is attached to both sides of the support column 2 by the square root bolt 41 and the nut 42 one by one. Here, the length in the longitudinal direction of the long gripping plate 11 is equal to the length of two of the support gripping plate 12 and the large-diameter antenna gripping plate 13 as shown in FIGS. 12 and the length of the small-diameter antenna gripping plate 14 so that the ends of the large-diameter antenna gripping plate 13 and the small-diameter antenna gripping plate 14 do not protrude from both sides of the long gripping plate 11.

  As shown in FIGS. 7A to 7D, the long holding plate 11 has a U-shaped cross section composed of upper and lower side surfaces 111 and 112 and a relay side surface 113 therebetween, and the upper and lower side surfaces 111 and 112. The column holding groove portions 111a and 112a having, for example, a V-groove shape in a plan view corresponding to the outer diameter of the column 2 are formed approximately in the middle in the longitudinal direction. Further, on both sides of the column holding groove portions 111a and 112a, antenna holding groove portions (hereinafter referred to as large antennas) having a semicircular shape in plan view corresponding to the outer diameter of the large-diameter rod-shaped antenna 31 to be attached as antenna holding portions, respectively. 111b and 112b are provided. Of course, the column holding groove portions 111a and 112a are not limited to the V-groove shape in a plan view, but may be a semicircular groove in a plan view.

  Further, the relay side surface 113 of the long gripping plate 11 is separated by 2 or more than the outer diameter of the column 2 so that the column 2 can be clamped and fixed by the column holding plate 12 opposed to the column 2 in a sandwiched manner. While two pillar clamping bolt holes 113a and 113a are provided, the large-diameter antenna 31 or the small-diameter antenna 32 is clamped by the antenna gripping plates 13 and 13 that are opposed to each other so as to sandwich the large-diameter antenna 31 or the small-diameter antenna 32. The two antenna clamping bolt holes 113b, 113b spaced apart from the outer diameter of the large-diameter antenna 31 are provided on both sides.

  Here, the antenna clamping bolt holes 113b and 113b are square bolt holes, whereas the column clamping bolt holes 113a and 113a are horizontally long rectangular bolt holes. This absorbs some errors in the outer diameter of the column 2 and secures the mounting and operating area of a tool such as a ratchet spanner. Furthermore, the bracket 1 is not the column 2 but the space between the bolt holes is narrow. This is because it can be attached to other members. In addition, since the pillar clamping bolt holes 113a and 113a and the antenna clamping bolt holes 113b and 113b are not circular but rectangular, the square root bolt 41 can be used as a bolt inserted into these bolt holes.

  Further, since the antenna clamping bolt holes 113b and 113b have a rectangular shape, as shown in FIGS. 4 to 6, when the column 2 is clamped by the long holding plate 11 and the column holding plate 12, While the head of the bolt 41 is located on the long gripping plate 11 side, when the small diameter antenna 32 is sandwiched between the long gripping plate 11 and the small diameter antenna gripping plate 14, the head of the square root bolt 41 is long. The square root bolt 41 is positioned in the opposite direction, being located on the scale grip plate 11 side. Therefore, the nut 42 is positioned on the back side and the front side of the long gripping plate 11, and the nut 42 is disposed on the opposite side via the long gripping plate 11 in the adjacent square root bolt 41. Therefore, it becomes easy to insert a tool such as a ratchet spanner, and the nut 42 is easily tightened. The antenna clamping bolt holes 113b and 113b may be round holes, but this effect cannot be obtained if they are round holes.

  As shown in FIGS. 8A to 8D, the column holding plate 12 has a U-shaped cross section composed of upper and lower side surfaces 121 and 122 and a relay side surface 123 therebetween, as with the long holding plate 11. Thus, in the middle of the longitudinal direction of the upper and lower side surfaces 121 and 122, columnar holding groove portions 121a and 122a having a V-groove shape in a plan view that contact the column 2 are provided. In addition, the relay side surface 113 is provided with two bolt holes 123 a and 123 a that are separated from each other by the outer diameter of the support column 2, and is provided to face the long holding plate 11 so as to sandwich the support column 2. Therefore, the column 2 is clamped from both sides by the column holding groove portions 111a and 112a having the V-groove shape in the plan view of the long holding plate 11 and the column holding groove portions 121a and 122a having the V groove shape in the plan view of the column holding plate 12. This is because the metal fitting 1 can be fixed to the top of the column 2. Even if the outer diameter of the support column 2 is slightly changed, the support column 2 can be securely and evenly held by the support member holding groove portions 111a and 112a having a V-groove shape in plan view and the support member holding groove portions 121a and 122a. Become.

  As shown in FIGS. 9A to 9D, the large-diameter antenna holding plate 13 has a U-shaped cross section composed of upper and lower side surfaces 131 and 132 and a relay side surface 133 therebetween. In the middle of the longitudinal direction of 132, antenna sandwiching groove portions (hereinafter referred to as large-diameter antenna sandwiching groove portions) 131a and 132a having a semicircular shape in plan view corresponding to the outer diameter of the large-diameter rod-shaped antenna 31 are provided. In addition, the relay side surface 133 is provided with square hole-shaped bolt holes 133 a and 133 a that are spaced apart from the outer diameter of the large-diameter antenna 31. Accordingly, as shown in FIGS. 1 to 3, when the column 2 is sandwiched between the long holding plate 11 and the column holding plate 12, the head of the square root bolt 41 is located on the long holding plate 11 side. On the other hand, when the large-diameter antenna 31 is sandwiched between the long gripping plate 11 and the large-diameter antenna gripping plate 13, the head of the square root bolt 41 is located on the large-diameter antenna gripping plate 13 side, The bolt 41 faces in the opposite direction. Therefore, similarly to the case of mounting the small-diameter antenna 32 shown in FIGS. 4 to 6, also in the case of mounting the small-diameter antenna 32 shown in FIGS. 11 is disposed on the opposite side via 11, a tool such as a ratchet spanner can be easily inserted, and the tightening operation of the nut 42 is facilitated. In the present invention, the bolt holes 133a and 133a may be round holes, but this effect cannot be obtained if the bolt holes 133a and 133a are round holes.

  As shown in FIGS. 10A to 10D, the small-diameter antenna holding plate 14 has a U-shaped cross section composed of upper and lower side surfaces 141 and 142 and a relay side surface 143 therebetween. The antenna holding groove portions 141a and 142a having a semicircular shape in plan view corresponding to the outer diameter of the small-diameter rod-shaped antenna 32 (hereinafter referred to as the small-diameter antenna holding groove portions) 141a and 142a are provided in the middle of the longitudinal direction. Are provided with bolt holes 143a and 143a having round holes which are spaced apart from the outer diameter of the small-diameter antenna 32. The bolt holes 143a and 143a may be square holes.

  Here, as is apparent from FIGS. 2B and 5B, the width of the relay side surface 133 of the large-diameter antenna gripping plate 13 in the short direction (up and down in FIG. 2B), that is, up and down The distance between both side surfaces 131 and 132 is substantially the same as the width in the same direction of the relay side surface 113 of the long gripping plate 11 and the width in the same direction of the relay side surface 123 of the column gripping plate 12, whereas the small-diameter antenna The width in the same direction of the relay side surface 143 of the holding plate 14 is smaller than those widths. This is because the large-diameter antenna 31 is heavier than the small-diameter antenna 32 and is more susceptible to wind resistance, so the large-diameter antenna gripping plate 13 that sandwiches the large-diameter antenna 31 sandwiches the small-diameter antenna 32. This is because stress and moment received from the rod-shaped antenna sandwiched from the small-diameter antenna holding plate 14 are increased, and it is necessary to increase the width to increase the proof stress. In addition, the small-diameter antenna 32 is provided with three screws (screws) 32a at the top and bottom at predetermined intervals on the base side as shown in FIGS. 4, 5A, 5B, and 6. Since the head of the screw 32a protrudes to the surface side, the vertical width of the relay side surface 143 of the small-diameter antenna gripping plate 14 is narrowed so that the head of the screw 32a at the base of the small-diameter antenna 32 comes into contact from above and below. In this way, the effect of dropping and retaining the small-diameter antenna 32 can be achieved.

  Further, as shown in FIGS. 9B and 10B, the large-diameter antenna holding groove portions 131a and 132a of the large-diameter antenna holding plate 13 and the small-diameter antenna holding groove portions 141a and 142a of the small-diameter antenna holding plate 14 are Although both have a semicircular shape in plan view, the small-diameter antenna holding groove portions 141a and 142a of the small-diameter antenna holding plate 14 are deeper and larger than the antenna holding groove portions 131a and 132a of the large-diameter antenna holding plate 13, that is, hold the small-diameter antenna. The groove portions 141a and 142a have a longer circumference of the semicircular portion, and the contact portions with the rod-shaped antenna are increased. This effect will be described later.

  Next, a method for attaching the large-diameter antenna 31 and the small-diameter antenna 32 to the column 2 using the above-described rod-shaped antenna mounting bracket 1 will be described.

(Mounting to column 2)
When the rod-shaped antenna mounting bracket 1 is attached to the support 2, similarly in the case of the large-diameter antenna 31 and the small-diameter antenna 32, first, as shown in FIGS. , 112 and the column holding groove portions 121a, 122a of the upper and lower side surfaces 121, 122 of the column holding plate 12 are arranged opposite to each other at positions where the column 2 is clamped from both sides.

  Next, the bolt holes 113a and 113a for holding the pillars on the relay side surface 113 of the long holding plate 11 (see FIG. 7C) and the bolt holes 123a and 123a on the relay side surface 123 of the column holding plate 12 (see FIG. 8). c) and the like.) The square-shaped bolt 41 is passed through and tightened with the nut 42, and the both sides of the support column 2 are clamped to attach the rod-shaped antenna mounting bracket 1 to the support column 2.

(Installation of large-diameter antenna 31)
And when attaching the two large diameter antennas 31 and 31 to the support | pillar 2, as shown in FIGS. 1-3, the large diameter antenna clamping groove part 111b, 112b of the up-and-down both sides 111,112 of the elongate holding plate 11 is shown. The large-diameter antennas 31 and 31 are clamped by the large-diameter antenna clamping grooves 111b and 112b of the upper and lower side surfaces 111 and 112 of the large-diameter antenna holding plates 13 and 13, respectively. Next, the antenna clamping bolt holes 113b and 113b (see FIG. 7C) on the relay side surface 113 of the long grip plate 11 and the bolt holes 133a and 133a on the relay side surface 133 of the large-diameter antenna grip plates 13 and 13 are used. The two large-diameter antennas 31 and 31 can be attached by passing the square root bolt 41 through the nut 42 and clamping both sides of the large-diameter antenna 31 (see FIG. 9C).

(Attaching the small-diameter antenna 32)
On the other hand, when two small-diameter antennas 32 and 32 are attached to the column 2, as shown in FIGS. 4 and 5, the back surface of the relay side surface 113 of the long grip plate 11 and the upper and lower portions of the small-diameter antenna grip plates 14 and 14 are arranged. The small-diameter antennas 32 and 32 are clamped by the small-diameter antenna clamping grooves 141a and 142a on both side surfaces 141 and 142. And antenna clamping bolt holes 113b and 113b (see FIG. 7C) on the relay side surface 113 of the long holding plate 11, and bolt holes 143a and 143a on the relay side surface 143 of the small-diameter antenna holding plates 14 and 14 (see FIG. 7). 10 (c)), and the two small-diameter antennas 32 and 32 can be attached by passing the square bolt 41 and tightening with the nut 42 to sandwich both sides of the small-diameter antenna 32.

  Therefore, according to the rod-shaped antenna mounting bracket 1 and the method of mounting the rod-shaped antennas having different diameters using the bracket 1, the column 2 is sandwiched between the long grip plate 11 and the column grip plate 12, and the column 2 is While the metal fitting 1 is attached, the antenna gripping plates 13 and 14 are prepared for each of the two or more large-diameter antennas 31 and 32 or the small-diameter antennas 32 and 32 to be attached, and the long gripping plate 11 and each antenna gripping plate 13, 14, two or more rod-shaped antennas 31, 32 are attached, so that one long holding plate 11 can be shared for mounting the column 2 and two or more rod-shaped antennas 31, 32. The number of parts can be reduced.

  Further, in this rod-shaped antenna mounting bracket 1, as is clear from a comparison between FIGS. 9A and 9B and FIGS. 10A and 10B, the large-diameter antenna holding groove portion of the large-diameter antenna holding plate 13 is used. Although 131a and 132a and the small-diameter antenna holding groove portions 141a and 142a of the small-diameter antenna holding plate 14 are both semicircular in plan view, the small-diameter antenna holding groove portions 141a and 142a of the small-diameter antenna holding plate 14 are By making the groove deeper than the antenna holding groove portions 131a and 132a of the plate 13 and increasing the circumference of the semicircular portions of the small-diameter antenna holding groove portions 141a and 142a, the number of contact portions with the rod-shaped antenna is increased. ing.

When attaching the large-diameter antenna 31, as shown in FIGS. 1 to 3, the large-diameter antenna holding grooves 111 b and 112 b on the upper and lower side surfaces 111 and 112 of the long grip plate 11, and the large-diameter antenna grip plate Since the large-diameter antenna 31 is clamped by the large-diameter antenna clamping grooves 111b and 112b of the upper and lower side surfaces 111 and 112 of the 13, 13, the portion that is in contact with the outer peripheral surface of the large-diameter antenna 31 is long. Both the large-diameter antenna holding groove portions 111b and 112b of the holding plate 11 and the large-diameter antenna holding groove portions 111b and 112b of the large-diameter antenna holding plates 13 and 13 are used.

  On the other hand, when the small-diameter antenna 32 is attached, as shown in FIGS. 4 to 6, the back surface of the relay side surface 113 of the long gripping plate 11 and the upper and lower side surfaces 141, 142 of the small-diameter antenna gripping plates 14, 14 are used. Since the small-diameter antenna 32 is clamped by the small-diameter antenna clamping grooves 141a and 142a, the contact portion between the back surface of the relay side surface 113 of the long gripping plate 11 and the small-diameter antenna 32 becomes almost a point in plan view and becomes short. This is because the holding force or the frictional force on the long holding plate 11 side is weakened, and this is compensated by the small-diameter antenna holding grooves 141a and 142a of the small-diameter antenna holding plates 14 and 14.

  As a result, according to this rod-shaped antenna mounting bracket 1, in order to sandwich the small-diameter antenna 32, while using the back surface of the relay side surface 113 instead of the large-diameter antenna sandwiching groove portions 111b and 112b of the long gripping plate 11, Since the holding force or the frictional force equivalent to the case of holding the large-diameter antenna 31 can be secured, the small-diameter antenna 32 can also be held similarly to the large-diameter antenna 31.

  In the description of the above embodiment, two rod-shaped antennas having the same diameter are provided on one column 2 such that two large-diameter antennas 31 or two small-diameter antennas 32 are provided by the rod-shaped antenna mounting bracket 1. However, the present invention is not limited to this, and three or more rod-shaped antennas having the same diameter may be attached to one support column 2. Further, different diameters may be attached to one support column 2. These rod-shaped antennas, for example, one large-diameter antenna 31 and one small-diameter antenna 32 may be attached one by one. However, when three or more rod-shaped antennas having the same diameter are attached to one support column 2, the long gripping plate 11 is also lengthened correspondingly, and the large-diameter antenna gripping plate 13 and the small-diameter antenna gripping plate 14 are also of the rod-shaped antenna. It is necessary to prepare only the number. For example, when one large-diameter antenna 31 and one small-diameter antenna 32 are attached to one support 2, the large-diameter antenna 31 is attached to the long-grip plate 11 on one side of the long-grip plate 11. While fixing the large-diameter antenna 31 by the large-diameter antenna holding groove portions 111b and 112b on the upper and lower side surfaces 111 and 112 and the large-diameter antenna holding groove portions 111b and 112b on the upper and lower side surfaces 111 and 112 of the large-diameter antenna holding plate 13, On the other side of the long gripping plate 11, the small-diameter antenna 32 is sandwiched between the back surface of the relay side surface 113 of the long gripping plate 11 and the small-diameter antenna sandwiching grooves 141 a and 142 a on both upper and lower side surfaces 141 and 142 of the small-diameter antenna gripping plate 14. Will do.

  Further, in this rod-shaped antenna mounting bracket 1, the long gripping plate 11 has been described with the large-diameter antenna holding groove portions 111 b and 112 b provided as the antenna holding portions on both sides of the column holding groove portions 111 a and 112 a. The antenna holding grooves 111b and 112b do not need to be provided and may be omitted. However, if omitted, the contact portion between the long holding plate 11 and the large-diameter antenna 31 is reduced, so that the large-diameter antenna holding plate 13 is the same as the small-diameter antenna holding grooves 141a and 142a of the small-diameter antenna holding plate 14. It is preferable that the large-diameter antenna holding groove portions 131a and 132a be deep or large so that the contact portion between the large-diameter antenna gripping plate 13 and the large-diameter antenna 31 increases.
