Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for mounting an antenna on a structure.
[0002]
[Prior art]
The conventional antenna mounting apparatus needs to select an appropriate mounting apparatus for a structure for mounting an antenna such as a wall or a fence.
[0003]
[Problems to be solved by the invention]
However, according to the conventional antenna mounting devices, the main body base is often made of a flat surface and cannot be mounted on the corners or round pillars of fences and walls. Further, since the main body base is flat, it is necessary to increase the thickness of the main body base in order to increase the strength of the main body base portion when the bolt is tightened. Therefore, it is an object to provide a strong and multi-use antenna mounting apparatus that can be mounted not only on a wall surface and a fence but also on a wall surface, a corner portion of a fence, and a round column.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an example of an embodiment embodying the present invention will be described in detail with reference to the drawings. FIG. 1 is an external perspective view showing an example in which the apparatus is attached to a fence. This antenna mounting device includes a main body base 1 that abuts on a vertical bone 50 made of a single circular column from the outside of the fence, a pipe-shaped antenna support 2 that is held by welding on the main body base 1, and an inner side of the fence. Consists of two sets of contact plates 3 that abut the opposite surface of the vertical bone 50, two sets of U-bolts 4 that fasten the base 1 and the contact plate 3, four sets of flat washers 5, spring washers 6 and nuts 7. Has been.
[0007]
The main body base 1 is formed with a protrusion 8 having a substantially square cross section in the vicinity of the approximate center of a substantially square metal plate in parallel with the antenna support 2 toward the outside of the structure. An L-shaped antenna support column is held by welding at a substantially central portion of the outer surface of the main body base.
[0008]
The contact plate 3 is formed in a substantially U-shaped cross-section by bending the long side of the rectangular metal plate toward the longitudinal bone 50 side, and the curved portion 9 is in contact with the round column at the substantially central portion of the bent metal plate. Is forming. Further, U-shaped bolt holes 10 are provided at both ends of the counter plate 3. Then, the main body base 1 and the curved portion 9 of the contact plate 3 are brought into contact with the vertical bone 50 made of a round column, and the U-shaped bolt 4 is applied to the main body base holes 11a, 11b and 11c, 11d from the U-shaped bolt hole of the applied plate 3. The flat washer 5, the spring washer 6, and the nut 7 are tightened and fixed from the front side of the main body base 1.
[0009]
According to the apparatus having the above configuration, the main body base 1 is formed with the protrusion 8 having a substantially square cross section in the vicinity of the approximate center of the substantially square metal plate in parallel with the antenna support 2 toward the outside of the structure. Therefore, even if it is attached to the vertical bone 50 made of a round pillar, the area where the main body base 1 and the round pillar come into contact with each other is increased as compared with the apparatus in which the main body base 1 is flat, and the attachment strength is increased. In addition, since the protrusion is formed on the main body base, the strength of the main body base is also increased.
[0010]
Next, a second example of use of the antenna mounting device of the present invention will be described with reference to FIG. In the following description, the same components as those of the antenna mounting device of the first embodiment are given the same reference numerals, and detailed description thereof is omitted.
[0011]
As described above, the main body base 1 of the device according to the present application has a protrusion 8 formed in a substantially square shape in cross section in the vicinity of the approximate center of a substantially square-shaped metal plate in parallel with the antenna column toward the outside of the structure. Therefore, it can be attached to the corner 51 of a building or a pillar. First, the contact plate 3, U-bolt 4, flat washer 5, spring washer 6, and nut 7 are removed from the main body base 1, and the inner surface side of the protrusion 8 of the main body base 1 is brought into contact with the corner 51 of the column. The inclined portion 15 is provided with a corner attachment hole 12, and is fixed to the corner portion 51 through the corner attachment hole 12 with a wood screw 12 or a nail. The corner attachment holes 12 in the embodiment of the present application are provided at four positions, and the positions are shifted from each other so that they do not collide when tightened with a wood screw 13 or a nail. The corner attachment holes 12 are not limited to the above locations, and may be provided as needed.
[0012]
The main body base 1 of the device of the present application has a protrusion 8 formed in a substantially square shape in cross section in the vicinity of the approximate center of a substantially square metal plate in parallel with the antenna support column toward the outside of the structure. At the same time, the main body base 1 is also provided with a flat surface portion 14, and the flat surface portion 14 forms a wall surface mounting hole 16, so that it can be fixed to a flat surface such as a wall surface or a column with a wood screw 13 or a nail, By reassembling the attachment direction of the contact plate 3 so that the bending direction of the long side of the metal plate is opposite to the longitudinal bone, it can be fixed to a plurality of longitudinal bones of the fence. Although the wall surface mounting holes 16 in the embodiment of the present application are provided at four places, the present invention is not limited to this and may be provided as needed.
In addition, as shown in FIG. 3, the pitch between the main body base holes 11a, 11b and 11c, 11d and the pitch between the main body base holes 11a, 11c and 11b, 11d are formed to be the same. 4 can be fixed to the lateral bone 52 of the fence by passing through the main body base holes 11a, 11c and 11b, 11d.
[0013]
As described above, the main body base 1 of the device of the present application has a protrusion formed in a substantially square cross section in the vicinity of the approximate center of a substantially square metal plate toward the outside of the structure parallel to the antenna column. 8, it is possible to easily install a satellite dish receiving parabolic antenna with one device of the present application regardless of the installation location.
In addition, this application is not limited to the said embodiment, It is also possible to change suitably the shape and structure of each part in the range which does not deviate from the meaning of this invention.
[0014]
As described in detail above, according to the first and second aspects of the present invention, the main body base is extended from the protrusions bent in a mountain shape so that the cross section is substantially perpendicular, and extended from both ends of the protrusions. Since the mounting holes for attaching the main body base directly to the structure are formed in the protrusions and the flat surface of the main body base , the strength and strength of the wall base and fence It is possible to provide an antenna mounting device that can be mounted on the corners and round pillars.
