Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an antenna pole mount for a television antenna.

[Conventional technology]

Generally, as shown in FIG. 7, a conventional antenna pole mount connects a support pipe 51 into which the antenna pole is inserted and supports it, and a mounting plate 52 which is attached to a building wall using two connecting pipes 53. The antenna pole fixing bolt 54 and a stopper (not shown) for supporting the lower end of the antenna pole were attached, and a mounting hole was provided in the mounting plate 52.

[Problem that the invention attempts to solve]

For this reason, since the support pipe 51, the mounting plate 52, and the connecting pipe 53 are manufactured individually, processing is time consuming and processing costs are high, resulting in an expensive product. Furthermore, since these components are joined by welding, the mounting plate 52 and the support pipe 5 may be damaged due to assembly errors, welding distortion, etc.
It was difficult to obtain parallelism with 1 and to achieve uniform quality. In addition, conventional products had uneven welding and cracks due to welding, and there was a risk that the welded parts would corrode and break relatively quickly when exposed to wind and rain.

The present invention was developed in view of the above points, and is an antenna that can improve dimensional accuracy, ensure parallelism between the support pipe and mounting plate, provide long-term use, uniform quality, mass production, and reduce product costs. The purpose is to provide pole attachments.

[Means for solving problems]

The first configuration of the present invention to achieve this purpose is

The mounting surfaces 10', 9' of the wing pieces 8', 7' of the other half-cylindrical member 4', 3' are at right angles to the mounting surfaces 5', 6' of the half-cylindrical member 4', and the half-cylindrical member with two wing pieces is provided. are integrally connected via the arm member 2' so that they are arranged symmetrically, and both mounting surfaces are equidistant from the intersection O of the extension lines of the mounting surfaces 5' and 6' of the half-cylindrical members 3' and 4'. position 11',
Two mounting pieces 1, 1 of a predetermined length are attached from an extruded profile 1' which is integrally formed with a dovetail-shaped protrusion 13' on one side of the extrusion 12' and a groove 14' that fits with the protrusion 13' on the other side. Cut these two mounting pieces 1, the half-cylindrical body 3 of 1,
4 are fitted into the protrusion 13 and the groove 14 and connected by a connector, and the antenna pole mounting bolt 18 is attached to the cylinder body 15 thus formed, and the wing plates 8 and 7 of the half cylinder body which are not connected are each fitted with a bolt 18. mounting hole 16,
form 17.

[Effect]

The present invention consists of two parts cut to a predetermined length from an extruded material 1' whose cross-sectional shape perpendicular to the longitudinal direction is always the same.
By fitting the two mounting pieces 1, 1 through the dovetail-shaped protrusions 13 and grooves 14 of the semi-cylindrical bodies 3, 4 and connecting them with connectors, a cylinder body 15 for the antenna pole is formed, and the connection Since the wing plates 8 and 7 on the side that is not attached serve as mounting seats to the building wall, the number of man-hours required to individually manufacture the cylindrical body part, arm part, and mounting base as in the past can be omitted, and quality can be made uniform and mass production can be achieved. can be achieved. Moreover, since each mounting piece 1, 1 obtained from the extruded section 1' has high dimensional accuracy, the cylindrical body 15
Parallelism between the blades 7 and 8, which serve as wall mounting seats, can be obtained. Furthermore, the mold for the extruded section 1' has a relatively simple shape and only one type of mold is required, so the mold cost is low and it is economical.

Embodiments of the present invention will be described based on the drawings. 6th
In the figure, 1' is a long aluminum alloy extruded section. This aluminum alloy extruded section 1' has two half-cylindrical members 3', 4' integrally connected by an arm member 2', and a mounting surface 5' of the half-cylindrical members 3', 4' on the other side, respectively.
Wing pieces 7', 8' are integrally provided at an obtuse angle with respect to 6', and the mounting surfaces 5', 6' of one half-cylindrical member 3', 4' are attached to the other half-cylindrical member 4', 6'. The mounting surfaces 10', 9' of the wing pieces 8', 7' of 3' are set at right angles, and the two half-cylindrical members with wing pieces are arranged symmetrically, and further,
Both mounting surface positions 11' and 1 are equidistant from the intersection O of the extension lines of the mounting surfaces 5' and 6' of both half-cylindrical members 3' and 4'.
2', for example, a dovetail protrusion 13' in the longitudinal direction at position 11', and a protrusion 13' in the longitudinal direction at position 12'.
3' is integrally formed with a groove 14' to be fitted into the groove 14'.

This aluminum alloy extruded section 1' has two temporary fixing holes 1 at a predetermined distance on both wing pieces 7' and 8'.
6 and three nail holes 17 are repeatedly drilled in succession, and then holes 1 for temporary fixing are made at both ends as shown in Fig. 1.
As shown in FIGS. 1 to 3, the two mounting pieces 1, 1 are cut to a predetermined length so as to have a cross section 6. A cylinder 15 is formed by fitting the mounting piece 1 with the groove 14 of the half cylinder 4 and connecting them integrally with a connector (not shown). The connected wing plates 8 and 7 serve as a mounting seat for mounting on the wall of a building, and a bolt 18 for fixing the antenna pole and a stopper 19 for supporting the lower end of the antenna pole are attached to the cylindrical body 15 of the fixture main body 1a.

The antenna pole fixture configured in this way is assembled by inserting the temporary fixing holes 16 into the temporary fixing screws that attach the pair of wing plates 7 and 8 on the non-connecting side to the building wall surface, and attaching them through the nail holes 17. Attach the antenna pole fixture to the wall of the building by driving a nail into the wall, then insert the antenna pole into the cylindrical body 15 and press the stopper 19.

Note that the present invention is not limited to the embodiments as described above, and may be modified within the scope of the gist of the present invention. For example, in the embodiment, the half cylinders 3 and 4 of the mounting piece 1 are Although a cylindrical surface is formed, this may be formed into an angular shape or other non-circular curved surface.

[Effect of idea]

As is clear from the above explanation, according to the present invention, the mounting piece constituting the antenna pole mount is obtained from an extruded member with a relatively simple cross-sectional shape. Accuracy is improved, and quality can be made uniform and mass production can be achieved. In addition, the mold for the extruded section has a relatively simple shape and only one type of mold is required, so the mold cost is low, and the product cost can be reduced. Also,
This mounting tool has two mounting pieces that are the same in shape and size and have high dimensional accuracy, which are fitted together using a dovetail-shaped protrusion and groove provided on a half cylinder, and are connected by a connector. Parallelism between the axis of the cylindrical body and the wing plate on the non-connected side, which will serve as the wall mounting seat, is obtained.
The antenna pole can be installed vertically, and
The number of man-hours required to separately manufacture the cylindrical body part, arm part, and mounting base as in the past can be omitted. In addition, since welding is not required, there is no welding distortion, corrosion or cracking of the welded parts, and it can withstand long-term use. Note that the use of extruded aluminum alloy shapes provides a beautiful appearance and is lightweight, making installation work easier.
