Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to solve the following problems.

(Field of industrial application) The present invention relates to an antenna support that can be used when an arbitrary antenna, for example, a parabolic antenna is attached to a building.

(Prior Art) Conventionally, there has been provided an antenna support tool in which a peripheral surface of a columnar antenna support member is connected and integrated to one surface of a flat plate-like substrate for mounting on a building (for example, Kokoku Shosho).
60-10094). However, the above-mentioned structure has a drawback that it is difficult to attach the above-mentioned substrate to a columnar column which is a building. It is also known that an U-shaped bolt is used to connect an antenna support member to a cylindrical column as a building (see, for example, Japanese Utility Model Publication No. 37-13341). However, the direction of relation between the columnar column and the antenna support member is fixed, and for example, when the column as a building is lying down, there is a drawback that it is difficult to attach to it.

(Problems to be Solved by the Invention) Except for the above-mentioned conventional problems, the present invention has a structure in which the pillar is a column, and the antenna supporting member is in an upright state or a recumbent state. It is an object of the present invention to provide an antenna support that can be properly fixed and can be attached to a wall of a house even if the column is a prism.

 The configuration of the present invention is as follows.

(Means for Solving Problems) The invention of the present application employs means as described in the claims, and its operation is as follows.

(Function) When the columnar column is in the state shown in FIG. 2, the U bolts are arranged in two steps and fixed. If the pillars are laid horizontally as shown in Fig. 5, install the U bolts in a state that they are installed side by side.
If the column is a prism, the orientation of the receiving member is changed as shown in FIG.

(Example) Hereinafter, drawings showing an example of the present application will be described. First
1 to 3, the antenna support 1 is configured as follows. A main body 1'composed by integrally connecting the peripheral surface of a columnar antenna supporting member 3 with a take-out rod 13 as a connecting member to one surface 2a of a flat plate-like substrate 2 for mounting on a building, for example, a cylinder 25. , Each of which has the substrate 2 on one surface thereof.
A flat attachment surface 18 for attaching to the other surface 10, the other surface having a circular concave surface 19 at the center, and flat attachment surfaces 20 for attaching to the other surface 10 of the substrate on both sides thereof, It has two receiving members 4, 4 provided with 20, in the receiving member 4, 4,
The dimension B between the one surface and the other surface is formed to be larger than the plate thickness F of the substrate, the two attachment surfaces 20 and 20 formed on both sides of the other surface, and the attachment surface 18 formed on the one surface. Through holes 21, 21 for penetrating the leg portion of the U bolt 5 in directions orthogonal to the two attachment surfaces 20, 20, respectively, are provided between
On the other hand, in each of the left and right four positions above and below the substrate 2, the through holes 11 and 8 are provided with the vertical and horizontal spacing dimensions E and E equal to the spacing between the two through holes 21 and 21 provided in the receiving members 4 and 4. 11 are arranged,
Furthermore, two U bolts 5 and 5 are provided, and leg portions 5a and 5a of the U bolts 5 and 5a are inserted between the through hole 21 of the receiving member 4 and the through hole 11 of the substrate 2 so that the space between the receiving member 4 and the head 5b of the U bolt is increased. Structure to be located
Substrate 2 can be attached to 25.

Note that, as shown in FIG. 7, a plurality of holes 12 for inserting the wood screws 40 are provided in the board 2 in consideration of the case where the board 2 is attached to a house. Next, the hollow cylindrical antenna support member 3
Is provided with a female screw hole 14 for attaching a bolt 16 for a push screw. The female screw hole 14 may be formed directly on the cylindrical body, or may be formed by welding a nut 15. Next, the hollow cylindrical support rods 13, 13 are
The one end is welded to the peripheral surface of the antenna support member 3 and the other end is welded to the one surface 2a of the substrate 2, respectively, to connect the two. Next, the receiving member 4 is formed by bending a plate material (iron plate having a thickness of 3.2 mm) into a U-shaped cross section as shown in the drawing. Next, the dimension A in the longitudinal direction of the receiving member 4, the dimension B in the thickness direction, the dimension C in the width direction of the arcuate concave surface 19, the radius of curvature D of the arcuate concave surface, the dimension E between the two through holes 21, 21, the substrate The plate thickness F of 2 and the bending angle G at the head of the U bolt are, for example, 130 mm, 20 mm, 30 mm, 16 mm, 90 mm and 3.2 mm.
If it is formed to have a size of mm and 130 degrees, a practical product can be manufactured. The receiving member 4 is made of a metal material such as aluminum.
The whole may be formed in a block shape as shown by an imaginary line in the figure.

Next, an example in which the parabolic antenna 27 is attached to the columnar pillar 25, which is a building, as shown in FIGS. A veranda 24 in a normal house 23 has a columnar column 25 for supporting a handrail railing or an eaves 25a. On the other hand, when mounting the antenna support 1, first, the receiving members 4, 4 are arranged so as to face the mounting surface 10 of the substrate in the main body 1'of FIG. Next, the outer surface of the cylinder 25 is brought into contact with the arcuate concave surfaces 19 and 19, the U bolts 5 and 5 are mounted in the state as shown in FIGS. 2 and 3, and the nut 6 is tightened. When the antenna support member 3 is short or short, a support column 26 for relay is mounted as shown in FIGS. That is, if the lower end of the support column 26 is inserted into the hollow portion of the antenna support member 3 and the bolt 16 presses it, both are integrated. Then, the parabolic antenna 27 may be attached to the upper part of the support pillar 26. Of course, when the antenna support member 3 extends upward long, the parabolic antenna 27 may be directly attached to the upper end of the antenna support member 3. As a result, the antenna support member 3
The axis 3a of is in a state substantially parallel to the axis of the cylinder 25. In FIG. 2, reference numeral 28 indicates a known supporting device (for example, it is known from JP-A-60-105302). Reference numerals 30, 31, 32, 33, 34 and the like indicate the presence of known reflecting mirrors, supporting arms, converters, primary radiators, and coaxial cables in order. After the antenna supporting member 3 is attached to the pillar 25 as shown in FIG. 2, the antenna supporting member 3 is not only in the left and right X directions but also in the upper and lower Y directions and on the board surface centered on the board 2. A firm supporting state is maintained in each of the following Z directions. Of course, in this mounted state, the receiving members 4 arranged above and below,
The respective arcuate concave surfaces 19 and 19 of 4 correspond to the outer peripheral surface of the cylinder 25 in the upper and lower directions, respectively. The thin plate thickness F is reinforced by the plate thickness B of the upper and lower receiving members 4, 4, respectively.

Next, FIG. 4 shows an example in which the outer peripheral shape of the columnar pillar 25 is square. In this case, if the direction of the receiving members 4, 4 is reversed from the case of FIG.
5'and the attachment surfaces 18 and 18 are in close contact with each other, while the mounting surface on the substrate 2
10 and the attachment surfaces 20 and 20 of the receiving members 4 and 4 are in close contact with each other to perform a reinforcing function, and at the same time, the prism 25 'and the main body 1'are integrated without rattling. The size of the arc concave surface 19 is
There may be a relationship shown by an imaginary line with respect to one side of the prism 25 '. Even in this state, the force applied from the prism 25 ′ to the attachment surface 18 directly from the attachment surface 20 to the attachment surface 10 via the receiving member 4.
In addition, the receiving member 4 reinforces the substrate 2 without bending. It should be noted that the parts and members designated by the same reference numerals as those in the previous figure have the same functions or are understood to be the same members, and therefore, duplicated description is omitted.

Next, FIG. 5 and FIG. 6 show an example of attachment to the horizontal rail 37 on the veranda 36. In this case, the direction of the receiving members 4, 4 and the arrangement of the U bolts 5, 5 are different from those in FIG. 2 as shown. That is, the receiving members 4, 4 are arranged vertically in the longitudinal direction of the receiving members 4, 4, and the U bolts 5, 5 are also arranged side by side in the longitudinal direction of the cross rail 37. This is possible because the left and right dimensions E of the four through holes 11, 11, 11, 11 provided in the substrate 2 and the upper and lower dimensions E are formed to be the same. In addition, in FIGS. 5 and 6, it is to be understood that the portions denoted by the same reference numerals as those in FIGS. 1 and 2 have the same members or functions.

FIG. 7 shows a case where the receiving members 4, 4 and the U-bolt 5 in FIG. 1 are used and the substrate 2 is directly attached to the wall surface 39 of the house 38. The holes 12 or 11 are used as the fastening means, and the wood screws 40 or other fasteners (for example, nails) are used for fastening.

FIG. 8 shows that the length of the take-out rod 13 is increased (the width of the reflecting mirror 30 is not
(1/2 or more) is shown below. If the take-out rod 13 has a sufficiently long take-out dimension, even if the reflecting mirror 30 in the parabolic antenna is rotated in any direction, for example, from the position shown by the solid line to the position shown by the alternate long and short dash line, the wall surface 39 of the house
The following shows an example in which the antenna can be sufficiently separated.

Next, FIG. 9 shows the board 2 of FIG. 1 and the antenna support member 3 which is a separate body from the board 2 as one plate member (for example, an iron plate).
An example of bending and manufacturing is shown below. That is, as the substrate corresponding to the substrate 2, the portion indicated by reference numeral 2e plays its role,
As the antenna support member 3, the portion indicated by 3e has that role. Reference numeral 13e indicates a connecting portion between the two. It should be noted that the members or portions denoted by the same reference numerals as those in FIG. 1 or the reference numerals with the letter “e” can be understood as members or portions having the same configuration or the same function as in the case of FIG. Therefore, redundant description will be omitted.

FIG. 10 shows another example of mounting the antenna 27. The figure is a view of the horizontal cross-shaped umbrella wood 44 provided on the balcony from below. (Baluster 45 and cylinder 43 show cutaway views). When the reinforcing rod 46 is used in such an attached state, even if the supporting member 3 is carried out from the substrate 2 by the carrying-out rod 13, the rolling of the supporting member 3 is strongly restricted, and the parabolic antenna 27 is kept in a stable position. Can be supported. In addition, 47 is a fastener (well-known bolt 47a and nut 4
7b), which is used to attach one end of the reinforcing rod 46 to a fixing hole 17 provided at the lower end of the supporting member 3. The attachment 48 is a reinforcing rod.
It is for fixing the other end of 46 to the handrail 45, and as is clear from the drawing, the handrail 45 and the reinforcing rod 46 are fixed by fastening the band members 49, 49 with the fastener 50. Of course, this reinforcing rod 46 is selectively placed at the position shown by the two-dot chain line on the opposite side,
Alternatively, they may be mounted in duplicate.

(Effects of the Invention) As described above, according to the present invention, when the antenna support is attached to the pillar 25 having a round cross section as shown in FIG. It can be fixed as shown in FIG. 3 with the arcuate concave surfaces 19 and 19 attached, and when the mounting is completed, the antenna support member 3 is attached to the pillar 25.
Has a feature that it can be firmly attached in any of the three-dimensional directions of X, Y, and Z.

Moreover, even when the antenna support is attached to the horizontal rail 37 of the veranda as shown in FIG. 5, the antenna support member 3
The arrangement of U bolts in the axial direction of is 90
As shown in FIGS. 5 and 6, they can be tightened side by side with different degrees, and even in this mounted state, they can be firmly mounted in the three directions of X, Y, and Z respectively.

Of course, in any of the above-mentioned cases, since the attachment surfaces 18, 18 of the receiving members 4, 4 are flat and adhere to the other surface (mounting surface) 10 of the substrate 2, as shown in FIG. Two
Is reinforced by the receiving member 4, and has an excellent feature that even if the substrate 2 is thin (though it is thin for weight reduction), it does not bend and can be kept flat.

Further, according to the present invention, even if the pillar or the horizontal rail 37 of the veranda as a building to be established is a prism as shown in FIG. 4, the receiving member 4 is turned upside down from the above case. When used as shown in FIG. 4, the attachment surface 18 faces the pillar 25 'or the cross rail 37, the arc concave surface 19 is located on the surface 10 side of the substrate, and the attachment surfaces 20, 20 are on the substrate 2. It has a feature that it is brought into contact with and integrated with the substrate 2 and exerts an effect of reinforcing the bending resistance of the substrate 2.

Further, since the substrate 2 and the receiving member 4 are separate bodies, there is an effect that the substrate 2 can be directly attached to the wall surface 39 as shown in FIG. 7 if the receiving member 4 is not used.
